Mental health problems in kids linked with school closures

Article Type
Changed

Behavior problems, anxiety, and depression in youths were associated with these individuals participating in remote schooling during broader social lockdowns in a new study.

The systematic review, which was published in JAMA Pediatrics on Jan. 18, 2022, was based on data from 36 studies from 11 countries on mental health, physical health, and well-being in children and adolescents aged 0-18 years. The total population included 79,781 children and 18,028 parents or caregivers. The studies reflected the first wave of pandemic school closures and lockdowns from February to July 2020, with the duration of school closure ranging from 1 week to 3 months.

“There are strong theoretical reasons to suggest that school closures may have contributed to a considerable proportion of the harms identified here, particularly mental health harms, through reduction in social contacts with peers and teachers,” Russell Viner, PhD, of UCL Great Ormond St Institute of Child Health, London, and colleagues wrote in their paper.

The researchers included 9 longitudinal pre-post studies, 5 cohort studies, 21 cross-sectional studies, and 1 modeling study in their analysis. Overall, approximately one-third of the studies (36%) were considered high quality, and approximately two-thirds (64%) of the studies were published in journals. Twenty-five of the reports analyzed focused on mental health and well-being.

Schools provide not only education, but also services including meals, health care, and health supplies. Schools also serve as a safety net and source of social support for children, the researchers noted.

The losses children may have experienced during school closures occurred during a time when more than 167,000 children younger than 18 years lost a parent or caregiver to COVID-19, according to a recent report titled “Hidden Pain” by researchers at the University of Pennsylvania, Nemours Children’s Health, and the COVID Collaborative. Although not addressed in the current study, school closures would prevent bereaved children from receiving social-emotional support from friends and teachers. This crisis of loss also prompted the American Academy of Pediatrics to issue a National State of Emergency in Children’s Mental Health in October 2021.
 

New study results

These studies identified associations between school closures during broader lockdowns and increased emotional and behavioral problems, as well as increased restlessness and inattention. Across these studies, 18%-60% of children and adolescents scored higher than the risk thresholds for diagnoses of distress, especially depressive symptoms and anxiety.

Although two studies showed no significant association with suicide in response to school closures during lockdowns, three studies suggested increased use of screen time, two studies reported increased social media use, and six studies reported lower levels of physical activity.

Three studies of child abuse showed decreases in notifications during lockdowns, likely driven by lack of referrals from schools, the authors noted. A total of 10 studies on sleep and 5 studies on diet showed inconsistent evidence of harm during the specific period of school closures and social lockdowns.

“The contrast of rises in distress with decreases in presentations suggests that there was an escalation of unmet mental health need during lockdowns in already vulnerable children and adolescents,” the researchers wrote. “More troubling still is evidence of a reduction in the ability of the health and social care systems to protect children in many countries, as shown by the large falls in child protection referrals seen in high-quality cohort studies.”
 

 

 

‘Study presents concrete assessments rather than speculation’

“Concerns have been widely expressed in the lay media and beyond that school closures could negatively impact the mental and physical health of children and adolescents,” M. Susan Jay, MD, of the Medical College of Wisconsin, Milwaukee, said in an interview. “The authors presented a narrative synthesis summarizing available evidence for the first wave of COVID-19 on school closures during the broader social lockdown occurring during this period.”

The “importance” of this research is that “it is not a single convenience sample study, but a systematic review from 11 countries including the United States, United Kingdom, China, and Turkey, among others, and that the quality of the information was graded,” Dr. Jay said. “Although not a meta-analysis, the study presents concrete assessments rather than speculation and overviews its limitations so that the clinician can weigh this information. Importantly, the authors excluded closure of schools with transmission of infection.

“Clearly, school lockdowns as a measure of controlling infectious disease needs balance with potential of negative health behaviors in children and adolescents. Ongoing prospective longitudinal studies are needed as sequential waves of the pandemic continue,” she emphasized.

“Clinically, this study highlights the need for clinicians to consider [asking] about the impact of school closures and remote versus hybrid versus in-person education [as part of their] patients and families question inventory,” Dr. Jay said. “Also, the use of depression inventories can be offered to youth to assess their mental health state at a visit, either via telemedicine or in person, and ideally at sequential visits for a more in-depth assessment.”
 

Schools play key role in social and emotional development

“It was important to conduct this study now, because this current time is unprecedented,” Peter L. Loper Jr., MD, of the University of South Carolina, Columbia, said in an interview. “We know based on evolutionary biology, anthropology, and developmental psychology, among other disciplines, that meaningful interpersonal interactions embedded in the context of community are vital to supporting human well-being.

Dr. Peter Loper

“In our current time, the primary framework of community for our children is the school setting; it is the predominant space where they engage in the interpersonal interactions necessary for developing resilience, their sense of purpose, belonging, and fidelity,” he emphasized.

“Rarely in the course of human existence have kids been removed from the broader context of community to this extent and for this duration,” Dr. Loper said. “This study capitalizes on this unprecedented moment to begin to further understand how compromises in our sociocultural infrastructure of community, like school closures and lockdowns, may manifest as mental health problems in children and adolescents. More importantly, it contributes to the exploration of potential unintended consequences of our current infection control measures so we can adapt to support the overall well-being of our children in this ‘new normal.’ ”

Dr. Loper added that he was not surprised by the new study’s findings.

“We were already seeing a decline in pediatric mental health and overall well-being in the years preceding COVID-19 because of the ‘isolation epidemic’ involving many of the factors that this study explored,” he said. “I think this review further illustrates the vital necessity of community to support the health and well-being of humans, and specifically children and adolescents.”

From a clinical standpoint, “we need to be intentional and consistent in balancing infection control measures with our kids’ fundamental psychosocial needs,” Dr. Loper said.

“We need to recognize that, when children and adolescents are isolated from community, their fundamental psychosocial needs go unmet,” he emphasized. “If children and adolescents cannot access the meaningful interpersonal interactions necessary for resilience, then they cannot overcome or navigate distress. They will exhibit the avoidance and withdrawal behaviors that accumulate to manifest as adverse mental health symptoms like anxiety and depression.

“Additional research is needed to further explore how compromises in the psychosocial infrastructure of community manifest as downstream symptom indicators such as anxiety and depression,” which are often manifestations of unmet needs, Dr. Loper said.
 

Limitations and strengths, according to authors

The findings were limited by several factors, including a lack of examination of school closures’ effects on mental health independent of broader social lockdowns, according to the researchers. Other limitations included the authors potentially having missed studies, inclusion of cross-sectional studies with relatively weak evidence, potential bias from studies using parent reports, and a focus on the first COVID-19 wave, during which many school closures were of limited duration. Also, the researchers said they did not include studies focused on particular groups, such as children with learning difficulties or autism.

The use of large databases from education as well as health care in studies analyzed were strengths of the new research, they said. The investigators received no outside funding for their study. The researchers, Dr. Jay, and Dr. Loper had no financial conflicts to disclose. Dr. Jay serves on the editorial advisory board of Pediatric News.

ACP advocates outpatient treatment of uncomplicated diverticulitis

Article Type
Changed

A pair of updated clinical guidelines from the American College of Physicians on the diagnosis and management of diverticulitis emphasized reduced use of antibiotics, outpatient management, and informed decision-making prior to elective surgery.

The estimated prevalence of acute colonic diverticulitis in the United States appears to be on the rise, wrote Amir Qaseem, MD, and members of the ACP Clinical Guidelines Committee. “Approximately 200,000 hospitalizations for acute left-sided colonic diverticulitis occur in the United States each year, with annual costs of more than $8 billion. Timely and correct diagnosis of acute left-sided colonic diverticulitis is essential for the selection of the most appropriate management options.”

Diverticulitis is becoming increasingly common in patients treated by internal medicine physicians, according to the ACP, and the new clinical guidelines specify a course of treatment focused on outpatient management and minimal medications.

The guidelines, published in Annals of Internal Medicine, were based on a systematic review of evidence from studies published between Jan. 1, 1990, and June 1, 2020. Notably, right-sided diverticulitis was excluded because it is rare in Western countries and involves a different natural history and management options, the authors wrote.

In the guidelines, uncomplicated diverticulitis refers to localized inflammation, and complicated diverticulitis refers to “inflammation associated with an abscess, a phlegmon, a fistula, an obstruction, bleeding, or perforation.”
 

Guidance on diagnosis and management

In the first guideline, “Diagnosis and Management of Acute Left-Sided Colonic Diverticulitis”, the authors provided three recommendations. First, they recommended that clinicians use abdominal CT imaging in cases of diagnostic uncertainty for patients with suspected acute left-sided colonic diverticulitis. The evidence showed that abdominal CT was associated with appropriate management in patients with suspected acute left-sided colonic diverticulitis, and that misdiagnosis with CT was rare.

Second, the authors of this guidance recommended management of most patients with acute left-sided colonic diverticulitis in an outpatient setting. Evidence showed that the risk for elective surgery and for recurrence were not significantly different based on inpatient or outpatient management.

The third recommendation advised clinicians to manage most patients without antibiotics. This recommendation was based on data showing no significant difference in quality of life at 3, 6, 12, or 24 months; no difference in diverticulitis-related complications; and no difference in the need for surgery in patients treated with antibiotics and those not treated with antibiotics.

All three recommendations are conditional, with low-certainty evidence, according to the authors.
 

Colonoscopy for diagnostic evaluation and interventions

In the second guideline, “Colonoscopy for Diagnostic Evaluation and Interventions to Prevent Recurrence After Acute Left-Sided Colonic Diverticulitis, the authors advised clinicians to refer patients for a colonoscopy after an initial episode of complicated left-sided colonic diverticulitis if they have not had a recent colonoscopy.

Although acute diverticulitis is usually uncomplicated, approximately 12% of cases are considered complicated, and these patients may have a higher prevalence of colorectal cancer, the authors noted. This recommendation was conditional, with low-certainty evidence. Additional diagnostic colonoscopy is not needed for patients who are up to date on recommended colorectal cancer screening, according to this guideline.

A second recommendation, given as a strong recommendation with high-certainty evidence, advised against using mesalamine to prevent recurrent diverticulitis. Evidence showed that use of mesalamine at doses ranging from 1.2 g/day to 4.8 g/day made no difference in recurrent diverticulitis risk compared with placebo. Mesalamine has no demonstrated clinical benefits, and has been associated with epigastric pain, nausea, diarrhea, dizziness, rash, and renal and hepatic impairment, the authors wrote.

The third recommendation advised the discussion of elective surgery with patients with a history of uncomplicated diverticulitis that persists or recurs frequently. Surgery also may be an option for patients with complicated diverticulitis, according to the guideline. However, “this recommendation does not apply to patients with uncomplicated diverticulitis that is not persistent or frequently recurring,” the authors wrote.

The decision to pursue elective surgery should be informed and personalized according to potential benefits, harms, costs, and patient preferences, they said. This recommendation is conditional, with low-certainty evidence.

This new guideline was designed “to guide care based on the best available evidence and may not apply to all patients or individual clinical situations,” the authors emphasized. “It should not be used as a replacement for a clinician’s judgment.”
 

 

 

Update confirms best practices

“Concerns about inappropriate antimicrobial therapy use and the delay in seeking preventative care such as a colonoscopy have led to poorer outcomes for patients,” ACP president George Abraham, MD, said in an interview. These concerns about a lack of antimicrobial stewardship and of care not being representative of ‘high value care’ “supported the need to reinforce best practices.”

Dr. George Abraham

Although most clinicians are aware of the nature of the recommendations in their own clinical practices, “a systematic review helped confirm and codify best practice that everyone can confidently incorporate into their daily decision-making,” Dr. Abraham said.

Compared with previous guidelines, “the single biggest difference is the fact that antimicrobial therapy is not indicated in mild, uncomplicated diverticulitis; we hope this will lead to lesser and more judicious antimicrobial prescribing,” Dr. Abraham emphasized.

Like all guidelines, the current guidelines are meant to be advisory, not mandatory; “they do not replace good clinical judgment and individual patient care decision-making,” Dr. Abraham said. “These guidelines are useful when they are widely read by clinicians, including physicians and advanced practice clinicians, and incorporated into their daily practice.”
 

Curbing antibiotic use

It is important for clinicians to recognize that uncomplicated diverticulitis in selected patients does not require initial antibiotics, David A. Johnson, MD, chief of gastroenterology at Eastern Virginia School of Medicine, Norfolk, said in an interview. “This paradigm shift began with the AGA guidelines in 2015, and was more recently updated with the 2021 best practice recommendations,” first published in Gastroenterology.

“I was surprised to see this current guideline not mentioning that, if antibiotics are to be used, that amoxicillin-clavulanate alone should be favored over combination of fluoroquinolones and metronidazole,” Dr. Johnson noted. “Furthermore, the U.S. Food and Drug Administration has advised that fluoroquinolones should be reserved for conditions with no alternative treatment options.”

“The initial management approach for the AGA guidelines and best practice are comparable with these most recent ACP recommendations,” said Dr. Johnson. However, “I would suggest that clinicians treating diverticulitis also review the AGA best practice recommendations, which build out important other important points for diverticulitis management including timeframes for colonoscopy, strong effect of genetics, dietary effects, recurrence rates, and the role of surgery.”

As for research gaps, “further data on cost savings would be helpful,” as savings may be likely with significant reduction without antibiotics and imaging in select patients, Dr. Johnson said. “Cost savings and risk reduction of adverse implications of antibiotic and radiation risks should be included in these analyses.”

The guidelines were based on systematic reviews conducted by the Evidence-based Practice Center at Brown University, Providence, R.I., funded by the Agency for Healthcare Research and Quality. The development of the guidelines was supported by the ACP operating budget. The authors, Dr. Abraham, and Dr. Johnson had no financial conflicts to disclose.

The decision to pursue elective surgery should be informed and personalized according to potential benefits, harms, costs, and patient preferences, they said. This recommendation is conditional, with low-certainty evidence.

This new guideline was designed “to guide care based on the best available evidence and may not apply to all patients or individual clinical situations,” the authors emphasized. “It should not be used as a replacement for a clinician’s judgment.”
 

 

 

Update confirms best practices

“Concerns about inappropriate antimicrobial therapy use and the delay in seeking preventative care such as a colonoscopy have led to poorer outcomes for patients,” ACP president George Abraham, MD, said in an interview. These concerns about a lack of antimicrobial stewardship and of care not being representative of ‘high value care’ “supported the need to reinforce best practices.”

Although most clinicians are aware of the nature of the recommendations in their own clinical practices, “a systematic review helped confirm and codify best practice that everyone can confidently incorporate into their daily decision-making,” Dr. Abraham said.

Compared with previous guidelines, “the single biggest difference is the fact that antimicrobial therapy is not indicated in mild, uncomplicated diverticulitis; we hope this will lead to lesser and more judicious antimicrobial prescribing,” Dr. Abraham emphasized.

Like all guidelines, the current guidelines are meant to be advisory, not mandatory; “they do not replace good clinical judgment and individual patient care decision-making,” Dr. Abraham said. “These guidelines are useful when they are widely read by clinicians, including physicians and advanced practice clinicians, and incorporated into their daily practice.”
 

Curbing antibiotic use

It is important for clinicians to recognize that uncomplicated diverticulitis in selected patients does not require initial antibiotics, David A. Johnson, MD, chief of gastroenterology at Eastern Virginia School of Medicine, Norfolk, said in an interview. “This paradigm shift began with the AGA guidelines in 2015, and was more recently updated with the 2021 best practice recommendations,” first published in Gastroenterology.

“I was surprised to see this current guideline not mentioning that, if antibiotics are to be used, that amoxicillin-clavulanate alone should be favored over combination of fluoroquinolones and metronidazole,” Dr. Johnson noted. “Furthermore, the U.S. Food and Drug Administration has advised that fluoroquinolones should be reserved for conditions with no alternative treatment options.”

“The initial management approach for the AGA guidelines and best practice are comparable with these most recent ACP recommendations,” said Dr. Johnson. However, “I would suggest that clinicians treating diverticulitis also review the AGA best practice recommendations, which build out important other important points for diverticulitis management including timeframes for colonoscopy, strong effect of genetics, dietary effects, recurrence rates, and the role of surgery.”

As for research gaps, “further data on cost savings would be helpful,” as savings may be likely with significant reduction without antibiotics and imaging in select patients, Dr. Johnson said. “Cost savings and risk reduction of adverse implications of antibiotic and radiation risks should be included in these analyses.”

The guidelines were based on systematic reviews conducted by the Evidence-based Practice Center at Brown University, Providence, R.I., funded by the Agency for Healthcare Research and Quality. The development of the guidelines was supported by the ACP operating budget. The authors, Dr. Abraham, and Dr. Johnson had no financial conflicts to disclose.

A pair of updated clinical guidelines from the American College of Physicians on the diagnosis and management of diverticulitis emphasized reduced use of antibiotics, outpatient management, and informed decision-making prior to elective surgery.

The estimated prevalence of acute colonic diverticulitis in the United States appears to be on the rise, wrote Amir Qaseem, MD, and members of the ACP Clinical Guidelines Committee. “Approximately 200,000 hospitalizations for acute left-sided colonic diverticulitis occur in the United States each year, with annual costs of more than $8 billion. Timely and correct diagnosis of acute left-sided colonic diverticulitis is essential for the selection of the most appropriate management options.”

Diverticulitis is becoming increasingly common in patients treated by internal medicine physicians, according to the ACP, and the new clinical guidelines specify a course of treatment focused on outpatient management and minimal medications.

The guidelines, published in Annals of Internal Medicine, were based on a systematic review of evidence from studies published between Jan. 1, 1990, and June 1, 2020. Notably, right-sided diverticulitis was excluded because it is rare in Western countries and involves a different natural history and management options, the authors wrote.

In the guidelines, uncomplicated diverticulitis refers to localized inflammation, and complicated diverticulitis refers to “inflammation associated with an abscess, a phlegmon, a fistula, an obstruction, bleeding, or perforation.”
 

Guidance on diagnosis and management

In the first guideline, “Diagnosis and Management of Acute Left-Sided Colonic Diverticulitis”, the authors provided three recommendations. First, they recommended that clinicians use abdominal CT imaging in cases of diagnostic uncertainty for patients with suspected acute left-sided colonic diverticulitis. The evidence showed that abdominal CT was associated with appropriate management in patients with suspected acute left-sided colonic diverticulitis, and that misdiagnosis with CT was rare.

Second, the authors of this guidance recommended management of most patients with acute left-sided colonic diverticulitis in an outpatient setting. Evidence showed that the risk for elective surgery and for recurrence were not significantly different based on inpatient or outpatient management.

The third recommendation advised clinicians to manage most patients without antibiotics. This recommendation was based on data showing no significant difference in quality of life at 3, 6, 12, or 24 months; no difference in diverticulitis-related complications; and no difference in the need for surgery in patients treated with antibiotics and those not treated with antibiotics.

All three recommendations are conditional, with low-certainty evidence, according to the authors.
 

Colonoscopy for diagnostic evaluation and interventions

In the second guideline, “Colonoscopy for Diagnostic Evaluation and Interventions to Prevent Recurrence After Acute Left-Sided Colonic Diverticulitis, the authors advised clinicians to refer patients for a colonoscopy after an initial episode of complicated left-sided colonic diverticulitis if they have not had a recent colonoscopy.

Although acute diverticulitis is usually uncomplicated, approximately 12% of cases are considered complicated, and these patients may have a higher prevalence of colorectal cancer, the authors noted. This recommendation was conditional, with low-certainty evidence. Additional diagnostic colonoscopy is not needed for patients who are up to date on recommended colorectal cancer screening, according to this guideline.

A second recommendation, given as a strong recommendation with high-certainty evidence, advised against using mesalamine to prevent recurrent diverticulitis. Evidence showed that use of mesalamine at doses ranging from 1.2 g/day to 4.8 g/day made no difference in recurrent diverticulitis risk compared with placebo. Mesalamine has no demonstrated clinical benefits, and has been associated with epigastric pain, nausea, diarrhea, dizziness, rash, and renal and hepatic impairment, the authors wrote.

The third recommendation advised the discussion of elective surgery with patients with a history of uncomplicated diverticulitis that persists or recurs frequently. Surgery also may be an option for patients with complicated diverticulitis, according to the guideline. However, “this recommendation does not apply to patients with uncomplicated diverticulitis that is not persistent or frequently recurring,” the authors wrote.

The decision to pursue elective surgery should be informed and personalized according to potential benefits, harms, costs, and patient preferences, they said. This recommendation is conditional, with low-certainty evidence.

This new guideline was designed “to guide care based on the best available evidence and may not apply to all patients or individual clinical situations,” the authors emphasized. “It should not be used as a replacement for a clinician’s judgment.”

AI holds its own against pathologists for prostate cancer diagnosis

Article Type
Changed

Artificial intelligence (AI) performs as well as expert uropathologists – and in some cases better than general pathologists – in diagnosing and grading prostate cancer, suggests a new study.

AI has shown promise in the diagnosis and grading of prostate cancer. However studies so far have been siloed, “with limited proof for generalization across diverse multinational cohorts, representing one of the central barriers to implementation of AI algorithms in clinical practice,” the investigators wrote in Nature Medicine.

Wouter Bulten, from the Radboud Institute for Health Sciences, Radboud University Medical Center, Nijmegen, the Netherlands, and coauthors reported the outcomes of the international PANDA histopathology competition, in which 1,290 deep learning algorithm developers were challenged to come up with reproducible algorithms that could match the findings of human experts. Deep learning is a form of machine learning in which artificial neural networks “learn” from large datasets and apply that learning in a similar way to the human brain. At least one AI product for detecting prostate cancer – the Paige Prostate system – has already been approved for clinical use in the United States. The Food and Drug Administration authorized marketing it in September 2021, as an adjunct to – but not replacement for – pathologist review.

The developers of the new algorithms participating in the competition were given a set of 10,616 digitized prostate biopsies to learn from, then were tested against a panel of either one to six – depending on the country – experienced uropathologists on a set of 393 digitized slides. A selection of 15 teams were then invited to take part in a validation phase with an additional 1,616 slides.

Within the first 10 days of the competition, one algorithm already achieved greater than 0.90 agreement with the uropathologists; by day 33, the median performance of all the teams in the competition was greater than 0.85 agreement with the human experts.
 

Algorithms correctly detected tumors in 99.7% of cases

The algorithms selected for validation showed even higher levels of agreement – 0.931 on average (95% confidence interval, 0.918-0.944). These algorithms correctly detected tumors in 99.7% of cases (95% CI, 98.1%-99.7%), and correctly identified 92.9% of negative results (95% CI, 91.9%-96.7%).

When it came to classifying the prostate cancers based on Gleason grade, the algorithms showed significantly more agreement with uropathologists than did an international panel of 13 or 20 general pathologists.

“This higher sensitivity shows promise for reducing pathologist workload by automated identification and exclusion of most benign biopsies from review,” the authors wrote.

The study found that the AI algorithms missed 1%-1.9% of cancers, but the general pathologists missed 1.8%-7.3%. The algorithms demonstrated a sensitivity of 96.4%-98.2% and specificity of 75%-100% for tumors, whereas the pathologists showed a sensitivity of 91.9-96.5% and specificity of 92.3%-95%.
 

Benign cases were misclassified

The main error that the algorithms made was misclassifying benign cases as ISUP GG 1 cancer. The authors commented that this was likely caused by a shift in the distribution of cases between the training data given to the algorithms and the data set they were validated on.

They also noted that, in one validation set, the algorithms overgraded a “substantial proportion” of ISUP GG 3 cases as GG 4, whereas general pathologists tended to undergrade cases, particularly in the higher-grade cancers.

“These differences suggest that general pathologists supported by AI could reach higher agreements with uropathologists, potentially alleviating some of the rater variability associated with Gleason grading,” they wrote.

The authors also pointed out that the algorithms were validated on individual biopsies from each patient, whereas in the clinical context, a pathologist would likely have multiple biopsies from a single patient.

“Future studies can focus on patient-level evaluation of tissue samples, taking multiple cores and sections into account for the final diagnosis,” they wrote.

The study was supported by the Dutch Cancer Society, Netherlands Organization for Scientific Research, Google, Verily Life Sciences, Swedish Research Council, Swedish Cancer Society, Swedish eScience Research Center, EIT Health, Karolinska Institutet, Åke Wiberg Foundation, Prostatacancerförbundet, Academy of Finland, Cancer Foundation Finland, and ERAPerMed. The authors declared a range of grants and funding outside the study, including from Philips Digital Pathology Solutions. Several authors declared patents related to prostate cancer diagnoses, and 10 were employees of Google.

Parent group warns of social media/eating disorders link

Article Type
Changed

A parents’ advocacy group with more than 2.5 million members nationwide sent an advisory to its members on Jan. 11, warning that social media’s January onslaught of messages for dieting and weight loss may be particularly harmful to kids struggling with weight and body image.

The guidance from ParentsTogether noted that such messages can trigger eating disorders and body dysmorphia. But some are particularly dangerous.

A Wall Street Journal investigation recently found that TikTok is distributing videos of rapid-weight-loss competitions and ways to purge food.

According to the ParentsTogether advisory, the Wall Street Journal also found TikTok has sent thousands of videos to teen accounts with messages such as “how to eat only 300 calories a day” or ”how to hide not eating from parents.” The group says similar messages appear on other social media platforms children use daily.

The seasonal January barrage of ads comes on top of a pandemic trend of worsening eating disorder patterns in young people worldwide.

Amanda Kloer, an organizer of the campaign behind the advisory and mother of two teenagers, said in an interview: “We know that January is a particularly sensitive month for this because of the amount of ad spending the wellness industry does.

“We wanted parents to be aware that while these risks exist year round, if they have a kid who is at risk, who is struggling a bit, they should pay particular attention to what they’re seeing on social media in January.”

Ms. Kloer sets up accounts on different platforms to test the messages a teen might receive and says the algorithms ramp up the frequency and the severity of the content as interest by the user grows.

“It sends kids down an extremely dangerous rabbit hole,” she said.

Debra Katzman, MD, with the division of adolescent medicine, department of pediatrics, University of Toronto, wrote in the Journal of Adolescent Health: “The COVID-19 pandemic has had a severe impact on individuals with eating disorders. Since the onset of the COVID-19 pandemic, eating disorder experts from across the globe have observed a substantial increase in the number and severity of new and preexisting young people suffering with eating disorders compared to prior years.”

Contributors beyond social media include lockdowns that bring steady access to food, distancing from peers, anxiety over school closures, and lack of a steady routine.

Eleanor Benner, PsyD, with Children’s Hospital of Philadelphia, said in an interview that awareness is growing regarding the increase in eating disorders correlated with social media use.

Dr. Eleanor Benner


Researchers and experts have acknowledged that social media use has increased and changed during the pandemic. Awareness is heightened as parents have been home with kids and noticing what kids are seeing online.

Dr. Benner, a psychologist for the eating disorder assessment and treatment program at CHOP, said platforms have made attempts to limit eating disorder content, but “the reality is that content producers can find ways around this, and unfortunately, we don’t know for whom exactly that content poses greatest risk of contributing to the onset of an eating disorder.”

The most important change for physicians and families to watch for is weight loss, Dr. Benner said.

“Weight loss or lack of weight in children and teenagers is not okay,” she said. “Kids and adolescents should be continually growing and gaining weight through their early 20s.”

Signs of trouble may include diet changes, rejections of favorite foods, and abnormal changes in physical activity, mood, and personality.

Dr. Benner said parents should feel empowered to share these changes with their pediatrician and request that the doctor not discuss weight in front of their children.

Parents should initiate conversations around what kids are seeing to help encourage critical questioning of social media content, Dr. Benner said.

“Parents can also promote body neutrality, the idea that bodies are neither good nor bad, that we don’t have to love our bodies, but acknowledge what they do for us and go about our lives without getting stuck on what they look or feel like,” she said.

Neutrality also extends to categorizing food, and Dr. Benner advised calling foods what they are – ice cream or broccoli, not “junk” or “healthy,” she said. “Food should not be a moral issue. Moralizing and labeling foods perpetuates diet culture and can contribute to shame and guilt around eating.”

ParentsTogether also called on social media platforms to:
  • Remove extreme content and stop sending weight-loss material to kids’ accounts: Social media platforms should remove the most extreme and dangerous content such as promoting skin lightening, the group said.
  • Create parental account settings. That way, parents can see what their kids see and initiate conversations about bodies and health.
  • Feature diverse content creators. The group urges platforms to promote creators with diverse personal appearances and backgrounds and those who support body acceptance and self-love.

ParentsTogether had collected more than 2,700 signatures by Jan. 13 on an online petition asking Instagram and TikTok to “Stop pushing extreme weight loss and dieting on kids.”

Pinterest became the first major platform to prohibit all weight loss ads, according to its announcement in July 2021.

The platform announced, “It’s an expansion of our ad policies that have long prohibited body shaming and dangerous weight loss products or claims. We encourage others in the industry to do the same and acknowledge, once and for all, that there’s no such thing as one size fits all.”

Ms. Kloer and Dr. Benner report no relevant financial relationships.

The platform announced, “It’s an expansion of our ad policies that have long prohibited body shaming and dangerous weight loss products or claims. We encourage others in the industry to do the same and acknowledge, once and for all, that there’s no such thing as one size fits all.”

Ms. Kloer and Dr. Benner report no relevant financial relationships.

A parents’ advocacy group with more than 2.5 million members nationwide sent an advisory to its members on Jan. 11, warning that social media’s January onslaught of messages for dieting and weight loss may be particularly harmful to kids struggling with weight and body image.

The guidance from ParentsTogether noted that such messages can trigger eating disorders and body dysmorphia. But some are particularly dangerous.

A Wall Street Journal investigation recently found that TikTok is distributing videos of rapid-weight-loss competitions and ways to purge food.

According to the ParentsTogether advisory, the Wall Street Journal also found TikTok has sent thousands of videos to teen accounts with messages such as “how to eat only 300 calories a day” or ”how to hide not eating from parents.” The group says similar messages appear on other social media platforms children use daily.

The seasonal January barrage of ads comes on top of a pandemic trend of worsening eating disorder patterns in young people worldwide.

Amanda Kloer, an organizer of the campaign behind the advisory and mother of two teenagers, said in an interview: “We know that January is a particularly sensitive month for this because of the amount of ad spending the wellness industry does.

“We wanted parents to be aware that while these risks exist year round, if they have a kid who is at risk, who is struggling a bit, they should pay particular attention to what they’re seeing on social media in January.”

Ms. Kloer sets up accounts on different platforms to test the messages a teen might receive and says the algorithms ramp up the frequency and the severity of the content as interest by the user grows.

“It sends kids down an extremely dangerous rabbit hole,” she said.

Debra Katzman, MD, with the division of adolescent medicine, department of pediatrics, University of Toronto, wrote in the Journal of Adolescent Health: “The COVID-19 pandemic has had a severe impact on individuals with eating disorders. Since the onset of the COVID-19 pandemic, eating disorder experts from across the globe have observed a substantial increase in the number and severity of new and preexisting young people suffering with eating disorders compared to prior years.”

Contributors beyond social media include lockdowns that bring steady access to food, distancing from peers, anxiety over school closures, and lack of a steady routine.

Eleanor Benner, PsyD, with Children’s Hospital of Philadelphia, said in an interview that awareness is growing regarding the increase in eating disorders correlated with social media use.

Researchers and experts have acknowledged that social media use has increased and changed during the pandemic. Awareness is heightened as parents have been home with kids and noticing what kids are seeing online.

Dr. Benner, a psychologist for the eating disorder assessment and treatment program at CHOP, said platforms have made attempts to limit eating disorder content, but “the reality is that content producers can find ways around this, and unfortunately, we don’t know for whom exactly that content poses greatest risk of contributing to the onset of an eating disorder.”

The most important change for physicians and families to watch for is weight loss, Dr. Benner said.

“Weight loss or lack of weight in children and teenagers is not okay,” she said. “Kids and adolescents should be continually growing and gaining weight through their early 20s.”

Signs of trouble may include diet changes, rejections of favorite foods, and abnormal changes in physical activity, mood, and personality.

Dr. Benner said parents should feel empowered to share these changes with their pediatrician and request that the doctor not discuss weight in front of their children.

Parents should initiate conversations around what kids are seeing to help encourage critical questioning of social media content, Dr. Benner said.

“Parents can also promote body neutrality, the idea that bodies are neither good nor bad, that we don’t have to love our bodies, but acknowledge what they do for us and go about our lives without getting stuck on what they look or feel like,” she said.

Neutrality also extends to categorizing food, and Dr. Benner advised calling foods what they are – ice cream or broccoli, not “junk” or “healthy,” she said. “Food should not be a moral issue. Moralizing and labeling foods perpetuates diet culture and can contribute to shame and guilt around eating.”

ParentsTogether also called on social media platforms to:
  • Remove extreme content and stop sending weight-loss material to kids’ accounts: Social media platforms should remove the most extreme and dangerous content such as promoting skin lightening, the group said.
  • Create parental account settings. That way, parents can see what their kids see and initiate conversations about bodies and health.
  • Feature diverse content creators. The group urges platforms to promote creators with diverse personal appearances and backgrounds and those who support body acceptance and self-love.

What does a pig-to-human heart transplant mean for medicine?

Article Type
Changed

Scientific achievements usually raise big new questions, and the remarkable surgery that took place on Jan. 7, when Maryland resident David Bennett was transplanted with a genetically modified heart from a pig, has been no different.

The 57-year-old with end-stage heart failure had been repeatedly turned down for a standard transplant and was judged a poor candidate for a ventricular assist device. Now his new heart is beating soundly and apparently accepted by his immune system as Mr. Bennett, his physicians at the University of Maryland where the procedure took place, and indeed the world set out on a journey with far more unknowns than knowns.

“I think even just a couple of years ago, people felt that xenotransplantation for the heart and other organs was still a long way off. And it seems like it’s started to move very quickly,” Larry A. Allen, MD, University of Colorado, Aurora, said in an interview.

Demand for donor hearts far outstrips supply, and despite advances in the development of ventricular assist pumps and artificial hearts, “there are still significant limitations to them in terms of clotting, stroke, and infection. We’ve seen the use of those devices plateau,” Dr. Allen said. “So, the concept of a nonhuman source of organs is exciting and very much in need, if people can get it to work.”

“I really credit the surgeons at the University of Maryland for courageous clinical work and a brilliant scientific innovation,” Clyde W. Yancy, MD, MSc, Northwestern University, Chicago, said in an interview. “But it’s always in the implementation that we have to hold our breath.” Heart xenotransplantation is an old idea that “has never before been successful,” he said. And standard heart transplantation has set a high bar, with a 1-year survival of about 90% and low 1-year risk for rejection. Whether the new procedure can meet that standard is unknown, as is its potential for complications, such as chronic rejection or cancers due to long-term immunosuppression. Those are “major questions requiring more time and careful follow-up.”

Dr. Clyde W. Yancy



 

‘Still a nascent technology’

“This is an exciting and courageous step forward in heart transplantation, and kudos to the team at the University of Maryland,” said Mandeep R. Mehra, MD, Brigham and Woman’s Hospital, Boston. But “there are many challenges here.”

The procedure’s 10 gene modifications were reportedly aimed at preventing hyperacute rejection of the heart and its excessive growth after transplantation, and making the organ less immunogenic, Dr. Mehra said in an interview. But even if those goals are met, could the same changes potentially impede the heart’s adaptation to human physiology, such as during ambulation or stress?

That kind of adaptation may become important. For example, Dr. Mehra observed, normally a pig heart “provides flow in a four-footed configuration, and pig temperature is inherently higher than humans by several degrees, so it will be functioning in a relatively hypothermic environment.”

Transplantation remains the gold standard for patients with advanced heart failure despite modern medical and device therapy, Dr. Allen agreed. But “if we can raise pig hearts that provide the organ, and it can be implanted with a surgery that’s been done for 50 years, and rejection can be managed with gene editing and tailored immunosuppression, then it’s not hard to think about this very rapidly replacing a lot of what we do in the advanced heart failure and transplantation world.”

Certainly, it would be a major advance if the gene editing technique successfully improves the heart’s immunologic compatibility, Dr. Yancy noted. But do we have enough genomic knowledge to select gene deletions and insertions in the safest way for a successful outcome? “We have to appreciate that this is still a nascent technology, and we should be careful that there might be consequences that we haven’t anticipated.”

For example, he said, the xenotransplantation and gene-modifying techniques should be explored in a range of patients, including older and younger people, women and men, and people of different ethnicities and races.

“There may be some differences based on ancestry, based on gender, based on aging, that will influence the way in which these engineered donor hearts are experienced clinically,” Dr. Yancy said.

The xenotransplantation technique’s potential impact on health equity should also be considered, as it “almost assuredly will be a very expensive technology that will be utilized in a very select population,” he noted. “We need to have a really wide lens to think about all of the potential ramifications.”
 

 

 

‘This field needs to evolve’

Dr. Mehra also flagged the procedure’s potential cost should it become mainstream. Perhaps that would promote dialogue on how to primarily use it “after legitimately exhausting all available options, such as total artificial heart support.”

It might also teach the field to take greater advantage of the many donated hearts discarded as suboptimal. “The general usage rate for offered organs is around a third,” despite opportunities to expand use of those that are “less than perfect,” Dr. Mehra said. “I think that the field will grow with the community focusing on reduced discards of current available heart organs, and not necessarily grow because of the availability of ‘xeno-organs.’ ”

“This field needs to evolve because we’re actively transplanting patients today. But in my mind, the real future is to have such a sufficient understanding of the biology of left ventricular dysfunction that transplantation is a rare event,” Dr. Yancy proposed.

“I’m not certain that heart transplantation per se is the endgame. I think the avoidance of transplantation is the real endgame,” he said. “This may be controversial, but my vision of the future is not one where we have a supply of animals that we can use for transplantation. My vision of the future is that heart transplantation becomes obsolete.”

Despite the stigma, ECT remains a gold standard

Article Type
Changed

For Clayton Lively, electroconvulsive therapy, or ECT, has been a lifesaver.

“ECT was like a last resort to treat mania and psychosis for bipolar disorder,” said the 31-year-old financial firm associate who lives in Silver Spring, Md. “I had tried lots of different medications.”

The first course of treatments – three times per week for several weeks – was in 2005. They helped tremendously. “I came down from my mania,” Mr. Lively said. “The hallucinations stopped. The psychosis disappeared.”

Thomas Northcut/Thinkstock

He reached a point where medications and psychotherapy worked again. And for a decade, his condition was under control.

But in 2017, another episode of hallucinations and mania jolted him off course. Intrusive thoughts returned. For instance, while driving, he would visualize veering off the road. The thoughts were jarring, and yet, he couldn’t stop them from recurring.

“I wasn’t sleeping, and it just kind of wreaked havoc on my life,” Mr. Lively recalled. “I ended up being hospitalized again.”

Once again, ECT came to the rescue – and yet again, in 2018. Now, he’s on an effective maintenance regimen, receiving ECT once every 4 weeks, after tapering down from more frequent sessions.

When a combination of antidepressants and psychotherapy fails to control severe mental illness, there’s hope on the horizon. ECT can be a reliably safe and effective option.

For some patients, using it as maintenance therapy makes sense, said Vaughn McCall, MD, editor-in-chief of The Journal of ECT and professor and chairman of psychiatry at the Medical College of Georgia in Augusta. “I would think of it the same way as you have to treat any chronic illness,” such as blood pressure medicine to keep hypertension in check and dialysis to prevent kidney failure.

Despite a cacophony of contrarian voices – mainly from the Church of Scientology – “the number of psychiatrists who see controversy in ECT is vanishingly small,” Dr. McCall said. “Within the discipline of psychiatry itself, there really is no controversy.”

In weighing the pros and cons of ECT, he noted that “when you’re trying to decide if it’s worth doing a treatment, you’re looking at the effectiveness on one hand and the side effects on the other hand.”

The answer to that emerges from several scales measuring patients’ quality of life by posing questions such as: “After receiving ECT, are you more able or less able to take care of yourself, to work, and enjoy the company of other people?”

In the end, Dr. McCall said, “we’ve applied these scales in probably half a dozen studies or more, and they always show that the patients’ qualify of life as a group is improved.”

recent study published in The Lancet Psychiatry provides a significant degree of reassurance that ECT – also called “electroshock” or colloquially just “shock” therapy – does not increase the risk of serious medical side effects. In fact, the study suggests a potential benefit in reducing suicide risk.

First performed in 1938, the treatment has been well documented in the medical literature. But negative portrayals in books and movies, such as the 1975 film “One Flew Over the Cuckoo’s Nest,” have contributed to casting it in an unfavorable light.

“Unfortunately, over the past decades and years, there’s a lot of stigma and fear around the treatment,” said the study’s lead author, Tyler Kaster, MD, a psychiatrist and clinical fellow in brain stimulation at the University of Toronto.

For the study, Canadian investigators reviewed the admission records of 10,000 patients hospitalized for at least 3 days because of a severe depressive episode. Nearly two-thirds of the patients were women, and the average age for the entire group approached 57 years.

While half of the patients underwent ECT, the others received medication and psychotherapy. Researchers found that the group undergoing ECT did not have a heightened risk of death over the next 30 days and were not any more likely to be hospitalized for a medical problem.

Previous ECT comparative studies were at high risk of bias because of their inability to sufficiently account for confounding variables and differences between those who received the treatment and those who did not. The current study employed “rigorous methods with careful attention to bias and confounding to overcome limitations of previous work,” the authors wrote.

They used propensity score matching, which included more than 75 variables, such as measures of cognitive impairment, depression severity, medication use, other illnesses, and use of psychiatric and various medical services, capacity to consent to treatment, and sociodemographic factors.

“This is really a landmark study in terms of showing the medical safety of ECT,” said Mark S. George, MD, professor of psychiatry and neurology at the Medical University of South Carolina, Charleston, who was not involved in the study.

Dr. Mark S. George

He added that “ECT is a life-saving treatment” for individuals with severe depression. “It’s good that we have this option for our patients.”

The authors highlight that depression is a major cause of illness and disability worldwide, with many individuals failing to achieve remission from initial therapies. Treatment-resistant depression is often described as being nonresponsive “to two or more medication trials of adequate dose and duration from different classes,” they wrote. In these instances, the authors point out, there is little evidence that psychotherapy would be helpful.

“The reason we consider ECT is someone has very severe depression that hasn’t responded to medications and talk therapy,” Dr. Kaster said. “The advantage of ECT is that it’s very effective in those circumstances.”

Of all therapies for treatment-resistant depression, ECT has the highest success rate, with 60% of patients attaining remission, according to the study, which cites prior research.

Compared with neurosurgery, the procedure is not invasive but requires general anesthesia. While the patient is asleep, Dr. Kaster said, the treating clinician places an electrical stimulus on the patient’s scalp, causing a generalized seizure inside the brain that lasts from 15 seconds to 2 minutes. 

A course of ECT usually takes a total of 8-12 treatments, delivered two to three times per week over a month to a month and a half, Dr. George said. 

Some patients need a new course of ECT if they relapse after several months. Others are unable to control their depression between courses and require repeated doses for maintenance. The time between these ECT sessions varies for each individual, Dr. George said, but is typically one session every 3-4 weeks. 

To improve the odds of staying well, patients typically need to continue taking antidepressants and engaging in psychotherapy.

“It helps improve the efficacy of ECT and also down the road helps prevent relapse,” Dr. Kaster said, noting that “depression is, unfortunately, a chronic illness. We don’t have a cure.”

Murat Altinay, MD, associate professor of psychiatry at the Cleveland Clinic and a mood disorders specialist, said his patients generally need to demonstrate a lack of response to at least three or four antidepressants before he considers recommending ECT.

Confusion, short-term memory impairment, and muscle aches and pains may occur after the procedure, but they are relatively mild. Patients are monitored in a recovery room before discharge from the hospital, Dr. Altinay said.

The first few treatments will affect everyday function. After that initial period, however, people can resume most of their daily activities, he said.

“Maybe they won’t be able to work full-time right away, but anecdotally, we have had patients who were able to go back to the workforce relatively quickly or while they’re getting ECT,” Dr. Altinay said.

More significant adverse events are very rare, he noted, although heart rate and blood pressure can become elevated because of the electrical stimulus.

Dr. Altinay said he is pleased that the large-scale journal article has been published to help dispel myths surrounding ECT. While psychiatrists feel that ECT is generally safe and effective, the public maintains a negative view.

“It is an underutilized treatment,” he said. “In the media, it is almost depicted as a barbaric and archaic treatment in psychiatry.”

Patients are afraid of major side effects such as personality changes. Some fear they will forget someone’s birthday or other important factual information, “but that kind of stuff obviously does not happen,” Dr. Altinay said.

Sometimes it’s not only the patients who are hesitant to try ECT; it’s the family members who express concerns, said Irving Reti, MBBS, professor of psychiatry and neuroscience and director of the brain stimulation program at the Johns Hopkins University, Baltimore.

“It varies from one patient to another how agreeable or reluctant or cautious they are about their treatment if the doctor thinks it’s indicated for them,” Dr. Reti said. “Family members’ concerns may be very legitimate but may also be influenced by stigma and misunderstanding about the treatment. They may also not fully appreciate the severity of their loved one’s depression that warrants the administration of ECT.”  

Hospitalized patients who are at risk of suicide have benefited from ECT. “It’s very effective,” he said. “I think it’s still the gold standard for severe treatment-resistant depression and also particularly helpful in people who are acutely suicidal.”

Dr. George cautioned that psychiatrists and the public should beware of questionable online sources that attempt to discredit ECT. “A quick Google search will find plenty of nonmedical doctors, many funded through Scientology, who will speak poorly of ECT. But they do not use evidence-based arguments and commonly do not treat patients,” he said.

“All good practicing psychiatrists that I know are in favor of ECT, as it clearly saves lives,” Dr. George added. “We all hope that the future will provide refinements of ECT, or even disruptive technologies that are more effective and with less hassle and will make ECT as we do it now obsolete. But we are not there yet.”

Once again, ECT came to the rescue – and yet again, in 2018. Now, he’s on an effective maintenance regimen, receiving ECT once every 4 weeks, after tapering down from more frequent sessions.

When a combination of antidepressants and psychotherapy fails to control severe mental illness, there’s hope on the horizon. ECT can be a reliably safe and effective option.

For some patients, using it as maintenance therapy makes sense, said Vaughn McCall, MD, editor-in-chief of The Journal of ECT and professor and chairman of psychiatry at the Medical College of Georgia in Augusta. “I would think of it the same way as you have to treat any chronic illness,” such as blood pressure medicine to keep hypertension in check and dialysis to prevent kidney failure.

Despite a cacophony of contrarian voices – mainly from the Church of Scientology – “the number of psychiatrists who see controversy in ECT is vanishingly small,” Dr. McCall said. “Within the discipline of psychiatry itself, there really is no controversy.”

In weighing the pros and cons of ECT, he noted that “when you’re trying to decide if it’s worth doing a treatment, you’re looking at the effectiveness on one hand and the side effects on the other hand.”

The answer to that emerges from several scales measuring patients’ quality of life by posing questions such as: “After receiving ECT, are you more able or less able to take care of yourself, to work, and enjoy the company of other people?”

In the end, Dr. McCall said, “we’ve applied these scales in probably half a dozen studies or more, and they always show that the patients’ qualify of life as a group is improved.”

recent study published in The Lancet Psychiatry provides a significant degree of reassurance that ECT – also called “electroshock” or colloquially just “shock” therapy – does not increase the risk of serious medical side effects. In fact, the study suggests a potential benefit in reducing suicide risk.

First performed in 1938, the treatment has been well documented in the medical literature. But negative portrayals in books and movies, such as the 1975 film “One Flew Over the Cuckoo’s Nest,” have contributed to casting it in an unfavorable light.

“Unfortunately, over the past decades and years, there’s a lot of stigma and fear around the treatment,” said the study’s lead author, Tyler Kaster, MD, a psychiatrist and clinical fellow in brain stimulation at the University of Toronto.

For the study, Canadian investigators reviewed the admission records of 10,000 patients hospitalized for at least 3 days because of a severe depressive episode. Nearly two-thirds of the patients were women, and the average age for the entire group approached 57 years.

While half of the patients underwent ECT, the others received medication and psychotherapy. Researchers found that the group undergoing ECT did not have a heightened risk of death over the next 30 days and were not any more likely to be hospitalized for a medical problem.

Previous ECT comparative studies were at high risk of bias because of their inability to sufficiently account for confounding variables and differences between those who received the treatment and those who did not. The current study employed “rigorous methods with careful attention to bias and confounding to overcome limitations of previous work,” the authors wrote.

They used propensity score matching, which included more than 75 variables, such as measures of cognitive impairment, depression severity, medication use, other illnesses, and use of psychiatric and various medical services, capacity to consent to treatment, and sociodemographic factors.

“This is really a landmark study in terms of showing the medical safety of ECT,” said Mark S. George, MD, professor of psychiatry and neurology at the Medical University of South Carolina, Charleston, who was not involved in the study.

He added that “ECT is a life-saving treatment” for individuals with severe depression. “It’s good that we have this option for our patients.”

The authors highlight that depression is a major cause of illness and disability worldwide, with many individuals failing to achieve remission from initial therapies. Treatment-resistant depression is often described as being nonresponsive “to two or more medication trials of adequate dose and duration from different classes,” they wrote. In these instances, the authors point out, there is little evidence that psychotherapy would be helpful.

“The reason we consider ECT is someone has very severe depression that hasn’t responded to medications and talk therapy,” Dr. Kaster said. “The advantage of ECT is that it’s very effective in those circumstances.”

Of all therapies for treatment-resistant depression, ECT has the highest success rate, with 60% of patients attaining remission, according to the study, which cites prior research.

Compared with neurosurgery, the procedure is not invasive but requires general anesthesia. While the patient is asleep, Dr. Kaster said, the treating clinician places an electrical stimulus on the patient’s scalp, causing a generalized seizure inside the brain that lasts from 15 seconds to 2 minutes. 

A course of ECT usually takes a total of 8-12 treatments, delivered two to three times per week over a month to a month and a half, Dr. George said. 

Some patients need a new course of ECT if they relapse after several months. Others are unable to control their depression between courses and require repeated doses for maintenance. The time between these ECT sessions varies for each individual, Dr. George said, but is typically one session every 3-4 weeks. 

To improve the odds of staying well, patients typically need to continue taking antidepressants and engaging in psychotherapy.

“It helps improve the efficacy of ECT and also down the road helps prevent relapse,” Dr. Kaster said, noting that “depression is, unfortunately, a chronic illness. We don’t have a cure.”

Murat Altinay, MD, associate professor of psychiatry at the Cleveland Clinic and a mood disorders specialist, said his patients generally need to demonstrate a lack of response to at least three or four antidepressants before he considers recommending ECT.

Confusion, short-term memory impairment, and muscle aches and pains may occur after the procedure, but they are relatively mild. Patients are monitored in a recovery room before discharge from the hospital, Dr. Altinay said.

The first few treatments will affect everyday function. After that initial period, however, people can resume most of their daily activities, he said.

“Maybe they won’t be able to work full-time right away, but anecdotally, we have had patients who were able to go back to the workforce relatively quickly or while they’re getting ECT,” Dr. Altinay said.

More significant adverse events are very rare, he noted, although heart rate and blood pressure can become elevated because of the electrical stimulus.

Dr. Altinay said he is pleased that the large-scale journal article has been published to help dispel myths surrounding ECT. While psychiatrists feel that ECT is generally safe and effective, the public maintains a negative view.

“It is an underutilized treatment,” he said. “In the media, it is almost depicted as a barbaric and archaic treatment in psychiatry.”

Patients are afraid of major side effects such as personality changes. Some fear they will forget someone’s birthday or other important factual information, “but that kind of stuff obviously does not happen,” Dr. Altinay said.

Sometimes it’s not only the patients who are hesitant to try ECT; it’s the family members who express concerns, said Irving Reti, MBBS, professor of psychiatry and neuroscience and director of the brain stimulation program at the Johns Hopkins University, Baltimore.

“It varies from one patient to another how agreeable or reluctant or cautious they are about their treatment if the doctor thinks it’s indicated for them,” Dr. Reti said. “Family members’ concerns may be very legitimate but may also be influenced by stigma and misunderstanding about the treatment. They may also not fully appreciate the severity of their loved one’s depression that warrants the administration of ECT.”  

Hospitalized patients who are at risk of suicide have benefited from ECT. “It’s very effective,” he said. “I think it’s still the gold standard for severe treatment-resistant depression and also particularly helpful in people who are acutely suicidal.”

Dr. George cautioned that psychiatrists and the public should beware of questionable online sources that attempt to discredit ECT. “A quick Google search will find plenty of nonmedical doctors, many funded through Scientology, who will speak poorly of ECT. But they do not use evidence-based arguments and commonly do not treat patients,” he said.

“All good practicing psychiatrists that I know are in favor of ECT, as it clearly saves lives,” Dr. George added. “We all hope that the future will provide refinements of ECT, or even disruptive technologies that are more effective and with less hassle and will make ECT as we do it now obsolete. But we are not there yet.”

For Clayton Lively, electroconvulsive therapy, or ECT, has been a lifesaver.

“ECT was like a last resort to treat mania and psychosis for bipolar disorder,” said the 31-year-old financial firm associate who lives in Silver Spring, Md. “I had tried lots of different medications.”

The first course of treatments – three times per week for several weeks – was in 2005. They helped tremendously. “I came down from my mania,” Mr. Lively said. “The hallucinations stopped. The psychosis disappeared.”

He reached a point where medications and psychotherapy worked again. And for a decade, his condition was under control.

But in 2017, another episode of hallucinations and mania jolted him off course. Intrusive thoughts returned. For instance, while driving, he would visualize veering off the road. The thoughts were jarring, and yet, he couldn’t stop them from recurring.

Health issues in women midlife linked with health decline at 65

Article Type
Changed

Having specific health issues, including depressive symptoms and cardiovascular disease, as a middle-aged woman was associated with experiencing clinically important declines in health later in life, a new study finds.

The most predictive parameters of poorer health at age 65 were cardiovascular disease, clinically significant depressive symptoms, and current smoking. Osteoarthritis, lower education level, and higher body mass index (BMI) also were associated with poorer health status 10 years on, Daniel H. Solomon, MD, MPH and colleagues wrote in their observational study, which was published in JAMA Network Open.

Dr. Daniel H. Solomon

Determining a patient’s score on a health-related quality of life measure based on these variables might be useful in clinical practice to recognize midlife patients at increased risk for later health deterioration, Dr. Solomon, of the division of rheumatology, inflammation, and immunity at Brigham and Women’s Hospital, Boston, said in a statement. This measure is called the Short Form 36 (SF-36), and the researchers specifically focused on the physical component summary score (PCS) of this measure. The SF-36 is similar to the Framingham 10-year coronary heart disease risk prediction score, according to Dr. Solomon, who is a professor of medicine at Harvard Medical School, also in Boston.

Based on their risk scores, women could preemptively target modifiable risk factors before they enter old age, the investigators wrote.

“Age 55-65 may be a critical decade. A person’s health and factors during this period may set them on a path for their later adult years,” Dr. Solomon said in a statement. “The good news is that a large proportion of women at midlife are very stable and will not go on to experience declines. But being able to identify women at higher risk could help lead to interventions targeted to them.”
 

Study details

The study included a cohort of 1,091 women drawn from the 3,302-participant Study of Women’s Health Across the Nation (SWAN), a racially and ethnically diverse group enrolled from six U.S. sites at or immediately before transition to menopause and followed for 10 years from age 55 to 65. The study sample, consisting of 24.6% Black, 24% Japanese or Chinese, and 51.9% White, had a median baseline age of 54.8 years and median BMI of 27 kg/m2 at entry. The median baseline PCS score was 53.1 (interquartile range, 46.8-56.7).

Over 10 years, 206 (18.9%) of the women in the study experienced clinically important declines of at least 8 points in baseline characteristics at around age 55. The following were significantly associated with these declines:

  • Having a higher BMI.
  • Having osteoarthritis.
  • Having a lower educational level.
  • Being a current smoker.
  • Having clinically significant depressive symptoms.
  • Having cardiovascular disease.
  • Having better (or higher) physical health and function score on the PCS.

The association between a higher PCS score and a greater decline might seem like an anomaly, Dr. Solomon said in an interview, but one interpretation of this finding is that women with higher or better scores at baseline have further to fall once other risk factors take effect.

With data analyzed from October 2020 to March 2021, the median 10-year change in PCS was –1.02 points, but 206 women experienced declines of 8 points or more.

Those with health declines were more likely to be Black and less likely to be Japanese. They were also more likely to have other comorbidities such as diabetes, hypertension, and osteoporosis, and to report less physical activity.
 

 

 

Scoring system should not replace individualized evaluation, outside expert said

Commenting on the findings, Margaret J. Nachtigall, MD, a clinical associate professor in the department of obstetrics and gynecology at New York University Langone Health, cautioned that a generalized scoring system should not replace individualized evaluation of women at midlife.

Dr. Margaret J. Nachtigall

“I assess women around age 55 on a daily basis for health risk factors going forward. And while a number such as BMI can be helpful, I worry that reliance on a score could miss treating the individual,” Dr. Nachtigall said an interview. For instance, one woman might have a high BMI owing to greater muscle mass, which is heavy, while another may have a lower BMI but more fat-related weight, as well as exacerbating conditions such as hypertension that would elevate her risk. “You have to make the calculation for each person.”

Dr. Nachtigall, who was not involved in the SWAN analysis, noted, however, that a big-data scoring system might be a useful adjunct to individual patient evaluation in that “it would make physicians look at all these many risk factors to identify those prone to decline.”
 

Study includes racially diverse population

According to the authors, while other studies have identified similar and other risk factors such as poor sleep, most have not included such a racially diverse population and have focused on women already in their senior years when the window of opportunity may already have closed.

“As a clinician and epidemiologist, I often think about the window of opportunity at midlife, when people are vital, engaged, and resilient,” said Dr. Solomon in the statement. “If we can identify risk factors and determine who is at risk, we may be able to find interventions that can stave off health declines and help put people on a better health trajectory.”

Dr. Eric M. Ascher

Eric M. Ascher, DO, who practices family medicine at Lenox Hill Hospital in New York and was not involved in the SWAN research, agreed with Dr. Solomon.

“Doctors who treat chronic conditions often meet patients when they are already suffering from a medical problem,” he said in an interview. “It is key to decrease your risk factors before it is too late.”

Dr. Ascher added that many primary care providers already rely heavily on scoring systems when determining level of risk and type of intervention. “Any additional risk factor-scoring systems that are easy to implement and will prevent chronic diseases would be something providers would want to use with their patients.”

Detailed analyses of larger at-risk populations are needed to validate these risk factors and identify others, the authors said.

SWAN is supported by the National Institute on Aging, the National Institute of Nursing Research, and the National Institutes of Heath’s Office of Research on Women’s Health. Dr. Solomon reported financial ties to Amgen, AbbVie and Moderna, UpToDate, and Arthritis & Rheumatology; as well as serving on the board of directors for the Childhood Arthritis and Rheumatology Research Alliance and an advisory committee for the Food and Drug Administration outside of this work. Dr. Nachtigall and Dr. Ascher disclosed no conflicts of interest with regard to their comments.

  • Having better (or higher) physical health and function score on the PCS.

The association between a higher PCS score and a greater decline might seem like an anomaly, Dr. Solomon said in an interview, but one interpretation of this finding is that women with higher or better scores at baseline have further to fall once other risk factors take effect.

With data analyzed from October 2020 to March 2021, the median 10-year change in PCS was –1.02 points, but 206 women experienced declines of 8 points or more.

Those with health declines were more likely to be Black and less likely to be Japanese. They were also more likely to have other comorbidities such as diabetes, hypertension, and osteoporosis, and to report less physical activity.
 

 

 

Scoring system should not replace individualized evaluation, outside expert said

Commenting on the findings, Margaret J. Nachtigall, MD, a clinical associate professor in the department of obstetrics and gynecology at New York University Langone Health, cautioned that a generalized scoring system should not replace individualized evaluation of women at midlife.

Dr. Margaret J. Nachtigall

“I assess women around age 55 on a daily basis for health risk factors going forward. And while a number such as BMI can be helpful, I worry that reliance on a score could miss treating the individual,” Dr. Nachtigall said an interview. For instance, one woman might have a high BMI owing to greater muscle mass, which is heavy, while another may have a lower BMI but more fat-related weight, as well as exacerbating conditions such as hypertension that would elevate her risk. “You have to make the calculation for each person.”

Dr. Nachtigall, who was not involved in the SWAN analysis, noted, however, that a big-data scoring system might be a useful adjunct to individual patient evaluation in that “it would make physicians look at all these many risk factors to identify those prone to decline.”
 

Study includes racially diverse population

According to the authors, while other studies have identified similar and other risk factors such as poor sleep, most have not included such a racially diverse population and have focused on women already in their senior years when the window of opportunity may already have closed.

“As a clinician and epidemiologist, I often think about the window of opportunity at midlife, when people are vital, engaged, and resilient,” said Dr. Solomon in the statement. “If we can identify risk factors and determine who is at risk, we may be able to find interventions that can stave off health declines and help put people on a better health trajectory.”

Dr. Eric M. Ascher

Eric M. Ascher, DO, who practices family medicine at Lenox Hill Hospital in New York and was not involved in the SWAN research, agreed with Dr. Solomon.

“Doctors who treat chronic conditions often meet patients when they are already suffering from a medical problem,” he said in an interview. “It is key to decrease your risk factors before it is too late.”

Dr. Ascher added that many primary care providers already rely heavily on scoring systems when determining level of risk and type of intervention. “Any additional risk factor-scoring systems that are easy to implement and will prevent chronic diseases would be something providers would want to use with their patients.”

Detailed analyses of larger at-risk populations are needed to validate these risk factors and identify others, the authors said.

SWAN is supported by the National Institute on Aging, the National Institute of Nursing Research, and the National Institutes of Heath’s Office of Research on Women’s Health. Dr. Solomon reported financial ties to Amgen, AbbVie and Moderna, UpToDate, and Arthritis & Rheumatology; as well as serving on the board of directors for the Childhood Arthritis and Rheumatology Research Alliance and an advisory committee for the Food and Drug Administration outside of this work. Dr. Nachtigall and Dr. Ascher disclosed no conflicts of interest with regard to their comments.

Pig heart successfully transplanted to man

Article Type
Changed

A genetically modified pig heart has been successfully transplanted into a 57-year-old man who had no other treatment options but is “doing well” 3 days after the procedure, officials at the University of Maryland Medical Center (UMMC), Baltimore, announced Jan. 10.

“This organ transplant demonstrated for the first time that a genetically modified animal heart can function like a human heart without immediate rejection by the body,” they said.

Three genes associated with antibody-mediated rejection had been knocked out in the pig supplying the transplanted heart, and six human genes associated with immune acceptance of the organ had been inserted into the pig’s genome, notes a UMMC press release.

“Lastly, one additional gene in the pig was knocked out to prevent excessive growth of the pig heart tissue, which totaled 10 unique gene edits made in the donor pig,” the release states.

The patient, Maryland resident David Bennett, had required mechanical circulatory support to stay alive but was rejected for standard heart transplantation at UMMC and other centers. He was ineligible for an implanted ventricular assist device due to ventricular arrhythmias.

Mr. Bennett “is being carefully monitored over the next days and weeks to determine whether the transplant provides lifesaving benefits,” the announcement says.

“We are proceeding cautiously, but we are also optimistic that this first-in-the-world surgery will provide an important new option for patients in the future,” notes a quote from Bartley P. Griffith, MD, the UMMC surgeon who performed the procedure.

The pig supplying the heart was provided to the center by Revivicor (Blacksburg, Virginia), a regenerative medicine company. An experimental antirejection medication (Kiniksa Pharmaceuticals; Lexington, Massachusetts) was also used, in addition to standard immunosuppressants.

Palliative care specialists seek greater role in lung disease

Article Type
Changed

Mrs. S.’s long-term chronic obstructive pulmonary disease (COPD) prognosis was grim, and she faced a harder time getting through each day. But neither she nor her primary care physician was willing to embrace strategies other than drugs.

“She felt guilty for continuing to smoke, but also expressed a need to smoke to help her deal with her husband’s cancer and eventual death,” recalled Georgia Narsavage, PhD, RN, ANP-BC, professor emerita of nursing at West Virginia University. “Her primary care physician was reluctant to introduce any treatment other than medications because her family was resistant to facing ‘mother dying.’ ”

SDI Productions/E+

But things changed when Mrs. S. was referred to a palliative-care clinical nurse specialist following a hospitalization. “The goal of palliative care is to support quality of life by relieving symptoms and decreasing suffering. She was assisted to improve functioning overall, and home support services were provided,” Dr. Narsavage said. “They allowed her to live at home relatively pain free with decreased dyspnea for 3 more years until her transition to hospice care a few months before death.

It wasn’t quite a happy ending. But it was a happier ending, and one that palliative care (PC) advocates hope will become more common in pulmonary care. They’re working to convince colleagues that PC is neither another word for hospice nor a sign that anyone is giving up on a patient.
 

Underutilized but beneficial

“Palliative care is underutilized in patients with chronic pulmonary disease, and it’s a missed opportunity to potentially alleviate symptoms and improve quality of life,” said Hilary DuBrock, MD, an internist and critical care pulmonologist with the Mayo Clinic in Rochester, Minn. “Chest physicians should know that it’s important to recognize your limitations in addressing all aspects of a chronic disease, and it’s OK to ask for help from a specialty multidisciplinary team of palliative care providers.”

Statistics back up Dr. DuBrock’s perspective about how PC isn’t common in pulmonary care. A 2017 study examined 181,689 U.S. adult patients who had COPD, received oxygen at home, and were hospitalized for exacerbations from 2006-2012. Just 1.7% received PC, although the number grew over the study period.

Another study published in 2017 examined 3,166 patients over the same period with end-stage idiopathic pulmonary fibrosis (IPF) who were on ventilators. The use of PC is group rose from 2.3% in 2006 to 21.6% in 2012.

More recently, a 2020 meta-analysis examined 19 studies and found that patients with lung cancer were much more likely to receive PC than were those with COPD (odds ratio (OR) = 9.59, P < .001, for hospital-based PC and OR = 8.79, P < .001, for home-based PC).

Patients with lung cancer vs. COPD were also less likely to receive invasive ventilation (OR = .26, P < .001), noninvasive ventilation (OR = .63, P = .009) or CPR (OR = .29, P < .001) or die at a nursing home/long-term care facility (OR = .32, P < .001).

Other studies support PC in COPD: Research in Europe has linked PC in COPD to fewer in-hospital deaths and lower end-of-life expenses. A Canadian study also linked PC to fewer in-hospital deaths in COPD.

Dr. DuBrock said she believes there are a couple reasons why PC isn’t more widely accepted in pulmonology. “There has been little evidence in chronic pulmonary disease regarding the role of PC, and there is a lack of standardized guidelines to help clinicians determine appropriate timing and patient selection for referral,” she said. “There is also a reluctance to refer patients to palliative care since some may think that referral implies that they are giving up on their patients.”

In fact, she said, “if appropriately explained and discussed with patients, PC does not necessarily need to imply to patients that you are giving up on them, but rather that you care enough about them to try to find novel ways to improve their quality of life and relieve their symptoms. Additionally, palliative care can be provided alongside ongoing medical care and treatment of their chronic lung disease.”
 

 

 

More than standard care

Another obstacle comes from pulmonologists who claim PC isn’t necessary because they’re handling patient care themselves, said University of Alabama at Birmingham critical care pulmonologist Anand S. Iyer, MD. “They’ll say: ‘I do palliative care, I palliate their breathing. I treat breathlessness and cough, that’s what I do.’ ”

But these symptoms only brush the surface of patient needs, he said. “I don’t think that the average pulmonologist goes beyond that to comprehensive symptom assessment and management of a whole host of symptoms beyond those limited to the lungs – depression, anxiety, fatigue, malnutrition.”

On that latter front, he said, pulmonologists “are really good at having end-of-life conversations at the end of life. We do that every day in the ICU.” Advocates for PC, he said, “want to push that to the clinic a year or two earlier.”
 

Timing and use of PC

When should pulmonologists call in a PC team? Specialists recommend early consultations, even right after a pulmonary disease is diagnosed. “When a pulmonologist diagnoses a condition as a serious illness – especially chronic pulmonary disease – a consultation with a palliative care physician or advanced practice registered nurse” can help assess the need for care and the best time to introduce palliative care to the patient and family “to provide relief and enhance quality of life,” West Virginia University’s Dr. Narsavage said. “Initial diagnosis is not too early to think about the trajectory.

Dr. Iyer agreed that early PC consultation is key. “We’re talking about comprehensive support for the physical, emotional, and spiritual needs of patients and their families. It can grow as needs of patients become more severe.”

For her part, Dr. DuBrock urged colleagues to focus on patient experiences. “The exact timing of when to refer patients with pulmonary disease is not well established,” she said. “Thus, it’s important to take cues from our patients. If they are experiencing significant symptom burden or impaired quality of life or having difficulty coping with their lung disease, then it may be helpful to call in palliative care to address these issues alongside education and discussion with the patient about the role of palliative care to address their unmet needs.”

As an example, Dr. DuBrock spoke of one of her own patients who has pulmonary hypertension (PH), connective tissue disease, and interstitial lung disease. “Her hypertension was relatively well controlled, but she was still quite symptomatic as well as depressed and having difficulty sleeping. I struggled with wanting to help her feel better but I also recognized that more PH therapy wasn’t necessarily the answer,” Dr. Dubrock said. “After some discussions, I referred her to palliative care, and they were extremely helpful with addressing her symptoms with a combination of pharmacologic and nonpharmacologic therapy and also addressing some of her underlying concerns and fears regarding her prognosis and issues related to advance-care planning. Social work was also helpful with addressing some of her financial concerns. I continue to see her on regular basis and treat her PH, but her overall quality of life, sleep, and mood have improved substantially.”
 

 

 

First steps

According to specialists, the first step in the PC process with patients is to make sure they understand their conditions, their prognoses, and the role of palliative care itself.

Kathleen Oare Lindell, PhD, RN, associate professor of nursing at Medical University of South Carolina, Charleston, who specializes in PC in pulmonary disease, remembers taking the histories of patients with grim prognoses and “their look on their face was like, ‘I just have a common cold.’ ” In other cases, she said, patients may fear they’ll die immediately when they have 3-5 years to live.

Dr. Lindell, who has worked at a specialty center for patients with interstitial lung disease (ILD), emphasized the importance of speaking in layperson terms that patients understand, such as referring to idiopathic pulmonary fibrosis as “unknown lung scarring.” She also said it’s crucial to be up front about their prognoses.

As for patient understanding of PC, she said, “people think it’s hospice that they’re giving. Palliative care is neither. Instead, it helps to address symptom management, I always tell patients, ‘You’ll be scared, you’ll have a cough. There are medicines and nonpharmacological therapies [that can help], and that’s what palliative care does.’ ”

Keith Swetz, MD, an internist and palliative care specialist at the University of Alabama at Birmingham, agreed that a concise discussion of prognosis is vital. “What do they know about their illness, and what do they understand about what will happen when things get worse?” he said.

“With pulmonary disease, they may be looking at months to years punctuated with a lot of ICU admissions, trips to the hospital, symptom burden, and decline in function. Some will want aggressive treatment and say they’re fine being in the hospital, while others will say being comfortable at home is more important.”

Dr. Swetz’s patients commonly have COPD, interstitial lung disease, pulmonary fibrosis, or PH, and some may have concurrent heart failure. While their prognoses may be poor, he said, discussion about their wishes probably aren’t happening outside of the PC setting.

Or if they are happening, he said, they’re lower quality, boiling down complicated care questions to “Do you want us to do everything yes, or no?

“A lot of it has to do with time,” he said. “Clinicians are busy, they might have a full ICU or pulmonary clinic with 15 minutes to see patients. Sitting down and talking about these things isn’t something that’s prioritized or fits into the work stream very well, and often it hasn’t been reimbursed.”

There typically aren’t insurance hassles regarding referrals for PC, Dr. Iyer said, although finding available specialists may be challenging. A 2019 study projected a wave of retirements of older PC physicians over the next few years, and the ratio of patients to PC specialists may not return to 2019 levels for decades. Rural areas are especially shorthanded. But telehealth may improve access, Dr. Iyer said.

What’s next? Specialists are trying to pin down guidelines for when PC consultation is appropriate in pulmonary disease.
 

Triggers to PC

Dr. Iyer, Dr. Lindell and others authored a 2021 report in the journal CHEST that offers guidance about triggers for PC consultation. The authors cited four “levers” or triggers that are important: worsening lung function, severe symptoms or high burden of care needs, poor prognosis, and frequent severe exacerbations.

“The overall point here is that integrating palliative care into COPD practice isn’t an on-off switch; rather, it should be based upon multiple factors and can evolve over time,” they wrote.

They noted that, “patients with COPD accept palliative care as early as moderate COPD (FEV1 < 80%), so patients may be ready sooner than clinicians think.”

They added that, “if prognosis is such a concern that a clinician is considering referral for lung transplant evaluation, then concurrent referral to specialist palliative care should be routine practice.

Finally, frequent severe exacerbations, i.e. those that require hospitalization or an emergency room visit, carry a high risk for posthospitalization mortality and are ideal inflection points in the illness trajectory of COPD.”

In the big picture, the authors contend, “palliative care should be integrated early and concurrently with COPD-directed therapies, and its intensity should increase over time as symptoms, needs, and exacerbations worsen approaching EOL [end of life].”

None of the interviewees or other authors reported having any relevant conflicts for this story.

A 2017 study examined 181,689 U.S. adult patients who had COPD, received oxygen at home, and were hospitalized for exacerbations from 2006-2012. Just 1.7% received PC, although the number grew over the study period.

Another study published in 2017 examined 3,166 patients over the same period with end-stage idiopathic pulmonary fibrosis (IPF) who were on ventilators. The use of PC is group rose from 2.3% in 2006 to 21.6% in 2012.

More recently, a 2020 meta-analysis examined 19 studies and found that patients with lung cancer were much more likely to receive PC than were those with COPD (odds ratio (OR) = 9.59, P < .001, for hospital-based PC and OR = 8.79, P < .001, for home-based PC).

Patients with lung cancer vs. COPD were also less likely to receive invasive ventilation (OR = .26, P < .001), noninvasive ventilation (OR = .63, P = .009) or CPR (OR = .29, P < .001) or die at a nursing home/long-term care facility (OR = .32, P < .001).

Other studies support PC in COPD: Research in Europe has linked PC in COPD to fewer in-hospital deaths and lower end-of-life expenses. A Canadian study also linked PC to fewer in-hospital deaths in COPD.

Dr. DuBrock said she believes there are a couple reasons why PC isn’t more widely accepted in pulmonology. “There has been little evidence in chronic pulmonary disease regarding the role of PC, and there is a lack of standardized guidelines to help clinicians determine appropriate timing and patient selection for referral,” she said. “There is also a reluctance to refer patients to palliative care since some may think that referral implies that they are giving up on their patients.”

In fact, she said, “if appropriately explained and discussed with patients, PC does not necessarily need to imply to patients that you are giving up on them, but rather that you care enough about them to try to find novel ways to improve their quality of life and relieve their symptoms. Additionally, palliative care can be provided alongside ongoing medical care and treatment of their chronic lung disease.”
 

 

 

More than standard care

Another obstacle comes from pulmonologists who claim PC isn’t necessary because they’re handling patient care themselves, said University of Alabama at Birmingham critical care pulmonologist Anand S. Iyer, MD. “They’ll say: ‘I do palliative care, I palliate their breathing. I treat breathlessness and cough, that’s what I do.’ ”

But these symptoms only brush the surface of patient needs, he said. “I don’t think that the average pulmonologist goes beyond that to comprehensive symptom assessment and management of a whole host of symptoms beyond those limited to the lungs – depression, anxiety, fatigue, malnutrition.”

On that latter front, he said, pulmonologists “are really good at having end-of-life conversations at the end of life. We do that every day in the ICU.” Advocates for PC, he said, “want to push that to the clinic a year or two earlier.”
 

Timing and use of PC

When should pulmonologists call in a PC team? Specialists recommend early consultations, even right after a pulmonary disease is diagnosed. “When a pulmonologist diagnoses a condition as a serious illness – especially chronic pulmonary disease – a consultation with a palliative care physician or advanced practice registered nurse” can help assess the need for care and the best time to introduce palliative care to the patient and family “to provide relief and enhance quality of life,” West Virginia University’s Dr. Narsavage said. “Initial diagnosis is not too early to think about the trajectory.

Dr. Iyer agreed that early PC consultation is key. “We’re talking about comprehensive support for the physical, emotional, and spiritual needs of patients and their families. It can grow as needs of patients become more severe.”

For her part, Dr. DuBrock urged colleagues to focus on patient experiences. “The exact timing of when to refer patients with pulmonary disease is not well established,” she said. “Thus, it’s important to take cues from our patients. If they are experiencing significant symptom burden or impaired quality of life or having difficulty coping with their lung disease, then it may be helpful to call in palliative care to address these issues alongside education and discussion with the patient about the role of palliative care to address their unmet needs.”

As an example, Dr. DuBrock spoke of one of her own patients who has pulmonary hypertension (PH), connective tissue disease, and interstitial lung disease. “Her hypertension was relatively well controlled, but she was still quite symptomatic as well as depressed and having difficulty sleeping. I struggled with wanting to help her feel better but I also recognized that more PH therapy wasn’t necessarily the answer,” Dr. Dubrock said. “After some discussions, I referred her to palliative care, and they were extremely helpful with addressing her symptoms with a combination of pharmacologic and nonpharmacologic therapy and also addressing some of her underlying concerns and fears regarding her prognosis and issues related to advance-care planning. Social work was also helpful with addressing some of her financial concerns. I continue to see her on regular basis and treat her PH, but her overall quality of life, sleep, and mood have improved substantially.”
 

 

 

First steps

According to specialists, the first step in the PC process with patients is to make sure they understand their conditions, their prognoses, and the role of palliative care itself.

Kathleen Oare Lindell, PhD, RN, associate professor of nursing at Medical University of South Carolina, Charleston, who specializes in PC in pulmonary disease, remembers taking the histories of patients with grim prognoses and “their look on their face was like, ‘I just have a common cold.’ ” In other cases, she said, patients may fear they’ll die immediately when they have 3-5 years to live.

Dr. Lindell, who has worked at a specialty center for patients with interstitial lung disease (ILD), emphasized the importance of speaking in layperson terms that patients understand, such as referring to idiopathic pulmonary fibrosis as “unknown lung scarring.” She also said it’s crucial to be up front about their prognoses.

As for patient understanding of PC, she said, “people think it’s hospice that they’re giving. Palliative care is neither. Instead, it helps to address symptom management, I always tell patients, ‘You’ll be scared, you’ll have a cough. There are medicines and nonpharmacological therapies [that can help], and that’s what palliative care does.’ ”

Keith Swetz, MD, an internist and palliative care specialist at the University of Alabama at Birmingham, agreed that a concise discussion of prognosis is vital. “What do they know about their illness, and what do they understand about what will happen when things get worse?” he said.

“With pulmonary disease, they may be looking at months to years punctuated with a lot of ICU admissions, trips to the hospital, symptom burden, and decline in function. Some will want aggressive treatment and say they’re fine being in the hospital, while others will say being comfortable at home is more important.”

Dr. Swetz’s patients commonly have COPD, interstitial lung disease, pulmonary fibrosis, or PH, and some may have concurrent heart failure. While their prognoses may be poor, he said, discussion about their wishes probably aren’t happening outside of the PC setting.

Or if they are happening, he said, they’re lower quality, boiling down complicated care questions to “Do you want us to do everything yes, or no?

“A lot of it has to do with time,” he said. “Clinicians are busy, they might have a full ICU or pulmonary clinic with 15 minutes to see patients. Sitting down and talking about these things isn’t something that’s prioritized or fits into the work stream very well, and often it hasn’t been reimbursed.”

There typically aren’t insurance hassles regarding referrals for PC, Dr. Iyer said, although finding available specialists may be challenging. A 2019 study projected a wave of retirements of older PC physicians over the next few years, and the ratio of patients to PC specialists may not return to 2019 levels for decades. Rural areas are especially shorthanded. But telehealth may improve access, Dr. Iyer said.

What’s next? Specialists are trying to pin down guidelines for when PC consultation is appropriate in pulmonary disease.
 

Triggers to PC

Dr. Iyer, Dr. Lindell and others authored a 2021 report in the journal CHEST that offers guidance about triggers for PC consultation. The authors cited four “levers” or triggers that are important: worsening lung function, severe symptoms or high burden of care needs, poor prognosis, and frequent severe exacerbations.

“The overall point here is that integrating palliative care into COPD practice isn’t an on-off switch; rather, it should be based upon multiple factors and can evolve over time,” they wrote.

They noted that, “patients with COPD accept palliative care as early as moderate COPD (FEV1 < 80%), so patients may be ready sooner than clinicians think.”

They added that, “if prognosis is such a concern that a clinician is considering referral for lung transplant evaluation, then concurrent referral to specialist palliative care should be routine practice.

Finally, frequent severe exacerbations, i.e. those that require hospitalization or an emergency room visit, carry a high risk for posthospitalization mortality and are ideal inflection points in the illness trajectory of COPD.”

In the big picture, the authors contend, “palliative care should be integrated early and concurrently with COPD-directed therapies, and its intensity should increase over time as symptoms, needs, and exacerbations worsen approaching EOL [end of life].”

None of the interviewees or other authors reported having any relevant conflicts for this story.

COVID-vaccine myocarditis: Rare, mild, and usually in young men

Article Type
Changed

The risk of myocarditis after immunization with mRNA-based vaccines against SARS-CoV-2 raised concerns when it came to light in early 2021. But as report after report showed such cases to be rare and usually mild and self-limited, focus has turned to the “how and why.”  

The mechanism linking the BNT162b2 (Pfizer-BioNTech) and especially mRNA-1273 (Moderna) vaccines to the occurrence of myocarditis is unclear for now, but one potential driver may be tied to a peculiarity that became apparent early: It occurs overwhelmingly in younger males, from 16 to perhaps 40 or 50 years of age. Excess risk has not been consistently seen among women, girls, and older men.

That observation has led to speculation that higher testosterone levels in adolescent boys and young men may somehow promote the adverse vaccine effect, whereas greater levels of estrogen among girls and women in the same age range may be cardioprotective.
 

Unlikely, brief, and ‘benign’

“Most of the myocarditis is benign, by which I mean that maybe the patients are admitted due to chest pain, but without reduction in ventricular function,” Enrico Ammirati, MD, PhD, a myocarditis expert at De Gasperis Cardio Center and Transplant Center, Niguarda Hospital, Milan, said in an interview.

In a Nov. 14 address on this topic at the annual scientific sessions of the American Heart Association, Dror Mevorach, MD, described the typical case presentation as “mild” and one that clears in fairly short order based on resolution of “clinical symptoms, inflammatory markers and troponin decline, EKG normalization, echo normalization, and a relatively short length of hospital stay.”

Dr. Mevorach, of Hadassah Hebrew University Medical Center, Jerusalem, subsequently published the findings in a report in the New England Journal of Medicine that described 136 confirmed myocarditis cases among more than 5 million people in Israel immunized with the Pfizer-BioNTech vaccine. Myocarditis was considered “mild” in 129 cases, or 95%.

And the risk is tiny, compared with myocarditis from infection by SARS-CoV-2, not to mention the possibility of nasty clinical COVID-19 complications such as pneumonia and pulmonary embolism, Dr. Mevorach observed.

Many other reports agree that the incidence is minimal, especially given the rewards of vaccination. In a separate NEJM publication in September 2021 – from Noam Barda, MD, Clalit (Israel) Research Institute, and colleagues on 1.7 million people in that country, about half unvaccinated and half given the Pfizer-BioNTech vaccine – there were an estimated 2.7 cases of  myocarditis per 100,000 vaccinated persons. There were also 11 cases of myocarditis per 100,000 persons who were positive for SARS-CoV-2 infection.

And in a recent case series of vaccinated people aged 16 or older, the myocarditis rate after a first or second Pfizer-BioNTech or Moderna injection was estimated at 1 or fewer per 100,000. The corresponding estimate was 4 such cases per 100,000 after a positive SARS-CoV-2 test among the same population, notes a report published Dec.14, 2021, in Nature Medicine.

In general, “the risk of any kind of cardiac injury is vastly lower with a vaccine than it is with the actual viral infection,” Leslie T. Cooper Jr., MD, a myocarditis expert and clinical trialist at the Mayo Clinic, Jacksonville, Fla., said in an interview. With the mRNA-based vaccines, “we do not have any conceivable danger signal that would outweigh the benefit of vaccination.”
 

 

 

Males of a certain age

Evidence that such myocarditis predominates in young adult men and adolescent boys, especially following a second vaccine dose, is remarkably consistent.

The risk was elevated only among mRNA-based vaccine recipients who were younger than 40 in the recent Nature Medicine analysis. Among that group, estimates after a second dose numbered fewer than 1 case per 100,000 for Pfizer-BioNTech and 1.5 per 100,000 for Moderna.

In a third analysis from Israel – also in NEJM, from Guy Witberg, MD, Rabin Medical Center, Petah Tikva, and colleagues, based on 2.5 million people aged 16 and older with at least one Pfizer-BioNTech injection – 2.1 cases per 100,000 were estimated overall, but the number rose to 10.7 per 100,000 among those aged 16-29 years.

In Dr. Mevorach’s NEJM report, estimates after a second Pfizer-BioNTech vaccine dose were 1 per 26,000 males versus 1 in 218,000 females, compared with 1 myocarditis case in 10,857 persons among “the general unvaccinated population.”

Most recipients of a first vaccine dose were younger than 50, and 16- to 29-year-olds accounted for most who completed two doses, noted Dr. Mevorach. Younger males bore the brunt of any myocarditis: the estimated prevalence after a second dose among males aged 16-19 was 1 per 6,637, compared with 1 per 99,853 females in the same age range, the group reported.

In the BMJ report, based on about 5 million people 12 years of age or older in Denmark, the estimated rates of myocarditis or pericarditis associated with Moderna immunization were 2 per 100,000 among women but 6.3 per 100,000 for men. The incidence and sex difference was much lower among those getting the Pfizer-BioNTech vaccine: 1.3 per 100,000 and 1.5 per 100,000 in women and men, respectively.
 

Sex hormones may be key

The predominance of vaccine-associated myocarditis among adolescent and young adult males is probably more about the myocarditis itself than the vaccines, observed Biykem Bozkurt, MD, PhD, who has been studying COVID-related myocarditis at Baylor College of Medicine, Houston.

Male sex historically is associated in both epidemiologic studies and experimental models with a greater propensity for most any form of myocarditis, Dr. Bozkurt said in an interview. Given that males aged 16-19 or so appear to be at highest risk of myocarditis as a complication of SARS-CoV-2 vaccination, the mechanism may well be related to sex hormones.  

“Therefore, testosterone is implicated as a player in their higher risk of inflammation and injury and lack of adaptive response in terms of healing, and in terms of prevention of injury,” Dr. Bozkurt said. For its part, estrogen inhibits proinflammatory processes and, in particular, “blunts cell-mediated immune responses.”

“We don’t know the mechanism, but a theory that attributes a protective role to estrogen, or a risk associated with testosterone, is reasonable. It makes sense, at least based on epidemiological data,” Dr. Ammirati agreed. Still, “we do not have any direct evidence in human beings.”

Sex-associated differences in experimental myocarditis have been reported in the journals for at least 70 years, but “the testosterone literature and the estrogen literature have not been evaluated in detail in vaccine-associated myocarditis,” Dr. Cooper said.

Most myocarditis in the laboratory is viral, Dr. Cooper observed, and “the links between testosterone, viruses, and inflammation have been pretty well worked out, I would say, if you’re a mouse. If you’re a human, I think it’s still a bit uncertain.”

Were it to apply in humans, greater testosterone levels might independently promote myocarditis, “and if estrogen is cardioprotective, it would be another mechanism,” Dr. Cooper said. “That would translate to slight male predominance in most kinds of myocarditis.”

In males, compared with females, “the heart can be more vulnerable to events such as arrhythmias or to immune-mediated phenomena. So, probably there is also higher vulnerability to myocarditis in men,” Dr. Ammirati noted.

Male predominance in vaccine-related myocarditis is provocative, so it’s worth considering whether testosterone is part of the mechanism as well as the possibility of estrogen cardioprotection, Dr. Ammirati said. But given limitations of the animal models, “we don’t really have robust data to support any part of that.”

Although myocarditis is in some way immune mediated, “and hormones can modulate the response,” the mechanism has to be more than just sex hormones, he said. “They probably cannot explain the specificity for the heart. It’s not a systemic response, it’s an organ-specific response.”
 

 

 

Modulation of immune responses

Details about the immune processes underlying mRNA-vaccine myocarditis, hormone modulated or not, have been elusive. The complication doesn’t resemble serum sickness, nor does it seem to be a reaction to infection by other cardiotropic viruses, such as coxsackie virus B, a cause of viral myocarditis, Dr. Bozkurt said. The latter had been a compelling possibility because such hypersensitivity to smallpox vaccination is well recognized.

“We don’t know the mechanism, that’s the short answer. But there are many hypotheses,” she said. One candidate widely proposed in the literature: autoantibodies driven by molecular mimicry between the SARS-CoV-2 spike protein targeted by the mRNA vaccines and a structurally similar myocardial protein, possibly alpha-myosin, noted Dr. Bozkurt and colleagues in a recent publication.

But elevations in specific “antiheart antibodies” have not been documented in recipients of the two mRNA-based vaccines, said Dr. Cooper. “So, I would say that – although molecular mimicry is a well-established mechanism of, for example, rheumatic carditis after a streptococcal A infection – that has not been demonstrated yet for COVID-19 mRNA vaccination–related myocarditis.”

“We probably won’t know, ever, with a huge level of certainty, the exact mechanisms,” Dr. Cooper added. There is no animal model for vaccine-induced myocarditis, and “We’re still talking very, very small numbers of patients. The vast majority of them recover,” and so don’t generally provide mechanistic clues.  
 

Prospects for younger children

Vaccination against SARS-CoV-2 has now been authorized by the Centers for Disease Control and Prevention for kids as young as 5-11 years, using the Pfizer-BioNTech vaccine. Experience so far suggests the immunization is safe in that age group with negligible risk of myocarditis or other complications. But with prospects of possible authorization in children younger than 5, should myocarditis be a concern for them?

Probably not, if the complication is driven primarily by sex hormones, Dr. Cooper proposed. “One would predict that before puberty you would have a lower – much, much lower – rate of myocarditis in males than you would in the 16- to 19-year-old range, and that it would be roughly equal to females.” Dr. Ammirati and Dr. Bozkurt largely agreed.

It remains to be seen whether the vaccine-related myocarditis risk applies to children younger than 12, “but I doubt it. I think it’s going to be puberty-related,” Dr. Bozkurt said. Still, “I don’t want to hypothesize without data.”

In a Nov. 14 address on this topic at the annual scientific sessions of the American Heart Association, Dror Mevorach, MD, described the typical case presentation as “mild” and one that clears in fairly short order based on resolution of “clinical symptoms, inflammatory markers and troponin decline, EKG normalization, echo normalization, and a relatively short length of hospital stay.”

Dr. Mevorach, of Hadassah Hebrew University Medical Center, Jerusalem, subsequently published the findings in a report in the New England Journal of Medicine that described 136 confirmed myocarditis cases among more than 5 million people in Israel immunized with the Pfizer-BioNTech vaccine. Myocarditis was considered “mild” in 129 cases, or 95%.

And the risk is tiny, compared with myocarditis from infection by SARS-CoV-2, not to mention the possibility of nasty clinical COVID-19 complications such as pneumonia and pulmonary embolism, Dr. Mevorach observed.

Many other reports agree that the incidence is minimal, especially given the rewards of vaccination. In a separate NEJM publication in September 2021 – from Noam Barda, MD, Clalit (Israel) Research Institute, and colleagues on 1.7 million people in that country, about half unvaccinated and half given the Pfizer-BioNTech vaccine – there were an estimated 2.7 cases of  myocarditis per 100,000 vaccinated persons. There were also 11 cases of myocarditis per 100,000 persons who were positive for SARS-CoV-2 infection.

And in a recent case series of vaccinated people aged 16 or older, the myocarditis rate after a first or second Pfizer-BioNTech or Moderna injection was estimated at 1 or fewer per 100,000. The corresponding estimate was 4 such cases per 100,000 after a positive SARS-CoV-2 test among the same population, notes a report published Dec.14, 2021, in Nature Medicine.

In general, “the risk of any kind of cardiac injury is vastly lower with a vaccine than it is with the actual viral infection,” Leslie T. Cooper Jr., MD, a myocarditis expert and clinical trialist at the Mayo Clinic, Jacksonville, Fla., said in an interview. With the mRNA-based vaccines, “we do not have any conceivable danger signal that would outweigh the benefit of vaccination.”
 

 

 

Males of a certain age

Evidence that such myocarditis predominates in young adult men and adolescent boys, especially following a second vaccine dose, is remarkably consistent.

The risk was elevated only among mRNA-based vaccine recipients who were younger than 40 in the recent Nature Medicine analysis. Among that group, estimates after a second dose numbered fewer than 1 case per 100,000 for Pfizer-BioNTech and 1.5 per 100,000 for Moderna.

In a third analysis from Israel – also in NEJM, from Guy Witberg, MD, Rabin Medical Center, Petah Tikva, and colleagues, based on 2.5 million people aged 16 and older with at least one Pfizer-BioNTech injection – 2.1 cases per 100,000 were estimated overall, but the number rose to 10.7 per 100,000 among those aged 16-29 years.

In Dr. Mevorach’s NEJM report, estimates after a second Pfizer-BioNTech vaccine dose were 1 per 26,000 males versus 1 in 218,000 females, compared with 1 myocarditis case in 10,857 persons among “the general unvaccinated population.”

Most recipients of a first vaccine dose were younger than 50, and 16- to 29-year-olds accounted for most who completed two doses, noted Dr. Mevorach. Younger males bore the brunt of any myocarditis: the estimated prevalence after a second dose among males aged 16-19 was 1 per 6,637, compared with 1 per 99,853 females in the same age range, the group reported.

In the BMJ report, based on about 5 million people 12 years of age or older in Denmark, the estimated rates of myocarditis or pericarditis associated with Moderna immunization were 2 per 100,000 among women but 6.3 per 100,000 for men. The incidence and sex difference was much lower among those getting the Pfizer-BioNTech vaccine: 1.3 per 100,000 and 1.5 per 100,000 in women and men, respectively.
 

Sex hormones may be key

The predominance of vaccine-associated myocarditis among adolescent and young adult males is probably more about the myocarditis itself than the vaccines, observed Biykem Bozkurt, MD, PhD, who has been studying COVID-related myocarditis at Baylor College of Medicine, Houston.

Male sex historically is associated in both epidemiologic studies and experimental models with a greater propensity for most any form of myocarditis, Dr. Bozkurt said in an interview. Given that males aged 16-19 or so appear to be at highest risk of myocarditis as a complication of SARS-CoV-2 vaccination, the mechanism may well be related to sex hormones.  

“Therefore, testosterone is implicated as a player in their higher risk of inflammation and injury and lack of adaptive response in terms of healing, and in terms of prevention of injury,” Dr. Bozkurt said. For its part, estrogen inhibits proinflammatory processes and, in particular, “blunts cell-mediated immune responses.”

“We don’t know the mechanism, but a theory that attributes a protective role to estrogen, or a risk associated with testosterone, is reasonable. It makes sense, at least based on epidemiological data,” Dr. Ammirati agreed. Still, “we do not have any direct evidence in human beings.”

Sex-associated differences in experimental myocarditis have been reported in the journals for at least 70 years, but “the testosterone literature and the estrogen literature have not been evaluated in detail in vaccine-associated myocarditis,” Dr. Cooper said.

Most myocarditis in the laboratory is viral, Dr. Cooper observed, and “the links between testosterone, viruses, and inflammation have been pretty well worked out, I would say, if you’re a mouse. If you’re a human, I think it’s still a bit uncertain.”

Were it to apply in humans, greater testosterone levels might independently promote myocarditis, “and if estrogen is cardioprotective, it would be another mechanism,” Dr. Cooper said. “That would translate to slight male predominance in most kinds of myocarditis.”

In males, compared with females, “the heart can be more vulnerable to events such as arrhythmias or to immune-mediated phenomena. So, probably there is also higher vulnerability to myocarditis in men,” Dr. Ammirati noted.

Male predominance in vaccine-related myocarditis is provocative, so it’s worth considering whether testosterone is part of the mechanism as well as the possibility of estrogen cardioprotection, Dr. Ammirati said. But given limitations of the animal models, “we don’t really have robust data to support any part of that.”

Although myocarditis is in some way immune mediated, “and hormones can modulate the response,” the mechanism has to be more than just sex hormones, he said. “They probably cannot explain the specificity for the heart. It’s not a systemic response, it’s an organ-specific response.”
 

 

 

Modulation of immune responses

Details about the immune processes underlying mRNA-vaccine myocarditis, hormone modulated or not, have been elusive. The complication doesn’t resemble serum sickness, nor does it seem to be a reaction to infection by other cardiotropic viruses, such as coxsackie virus B, a cause of viral myocarditis, Dr. Bozkurt said. The latter had been a compelling possibility because such hypersensitivity to smallpox vaccination is well recognized.

“We don’t know the mechanism, that’s the short answer. But there are many hypotheses,” she said. One candidate widely proposed in the literature: autoantibodies driven by molecular mimicry between the SARS-CoV-2 spike protein targeted by the mRNA vaccines and a structurally similar myocardial protein, possibly alpha-myosin, noted Dr. Bozkurt and colleagues in a recent publication.

But elevations in specific “antiheart antibodies” have not been documented in recipients of the two mRNA-based vaccines, said Dr. Cooper. “So, I would say that – although molecular mimicry is a well-established mechanism of, for example, rheumatic carditis after a streptococcal A infection – that has not been demonstrated yet for COVID-19 mRNA vaccination–related myocarditis.”

“We probably won’t know, ever, with a huge level of certainty, the exact mechanisms,” Dr. Cooper added. There is no animal model for vaccine-induced myocarditis, and “We’re still talking very, very small numbers of patients. The vast majority of them recover,” and so don’t generally provide mechanistic clues.  
 

Prospects for younger children

Vaccination against SARS-CoV-2 has now been authorized by the Centers for Disease Control and Prevention for kids as young as 5-11 years, using the Pfizer-BioNTech vaccine. Experience so far suggests the immunization is safe in that age group with negligible risk of myocarditis or other complications. But with prospects of possible authorization in children younger than 5, should myocarditis be a concern for them?

Probably not, if the complication is driven primarily by sex hormones, Dr. Cooper proposed. “One would predict that before puberty you would have a lower – much, much lower – rate of myocarditis in males than you would in the 16- to 19-year-old range, and that it would be roughly equal to females.” Dr. Ammirati and Dr. Bozkurt largely agreed.

It remains to be seen whether the vaccine-related myocarditis risk applies to children younger than 12, “but I doubt it. I think it’s going to be puberty-related,” Dr. Bozkurt said. Still, “I don’t want to hypothesize without data.”
