The Odoribacter splanchnicus strain of human donor-derived bacteria correlated with clinical response to ulcerative colitis in study in which mouse models were colonized with patient-derived strains.

Although some recent trials have shown the effectiveness of fecal microbiota transplantation (FMT) for patients with ulcerative colitis (UC), the current process is limited by the used of crude donor fecal material, which increases the risk of infection and decreases potential effectiveness, Svetlana Lima, MD, of Weill Cornell Medicine, New York, and colleagues wrote.

“Rational selection and production of specific microbial strains or communities could improve efficacy, minimize the risk of adverse reactions as well as increase the acceptance of microbiome-based therapies,” the researchers wrote.

In a study published in Gastroenterology, the researchers used metagenomic analysis and IgA sequencing (for sorting and sequencing IgA-coated microbiota) to identify a core of transferable and IgA-coated microbiota. They conducted metagenomic sequencing on 60 stool samples, including 20 recipient-participants with active UC who were treated with FMT, and another 20 FMT recipients with data from 4 weeks after FMT from a previously reported trial.

The core transferable microbiota (CTM) included 22 species of bacteria at 4 weeks after FMT. To determine a relationship between CTM and clinical response to FMT, the researchers defined clinical response as a decrease in Mayo score of 3 or greater with a rectal bleeding score of 1 or less by 4 weeks after FMT; 35% of study participants met this endpoint.* A total of 20 species were unique to the responders. “Of the donor-derived genera, only the relative abundance of Odoribacter at [week 4] post FMT and its increase post FMT was found to significantly correlate with decrease in Mayo score,” the researchers noted.

The researchers then colonized germ-free or genetically engineered mice with patient-derived bacterial strains.

O. splanchnicus also increased induction of interleukin-10, and increased the production of short-chain fatty acids. Taken together, these factors allowed for O. splanchnicus to limit colitis in the mice.

The study findings represent the first strain-level analysis of FMT in UC participants, and define a transferable microbiota associated with clinical response that could serve as a prognostic biomarker, the researchers noted in their discussion section. Although analysis revealed 12 donor-derived bacterial species that predicted clinical response, further IgA analysis identified O. splanchnicus as “the only microbe within the responders core that correlates with clinical response and highlights the potential impact of this taxa seen in independent cohorts, as well as mouse models of colitis and colorectal cancer,” the researchers emphasized.

The study findings were limited by the small sample size and the lack of prospective data. However, “collectively, this work provides the first evidence of transferable, donor-derived strains that correlate with clinical response to FMT in UC and reveals O. splanchnicus as a key component, which mechanistically promotes protection through both cellular and metabolic function,” the researchers said. “These mechanistic features will help enable desperately needed strategies to enhance therapeutic efficacy of microbial therapy for UC.”
 

Study strains improve effectiveness

“There is an accumulating body of evidence that suggests that gut dysbiosis, or the imbalance between good and bad microbes, plays an important role in the pathogenesis and progression of ulcerative colitis,” Jeffrey Berinstein, MD, of the University of Michigan, Ann Arbor, said in an interview. “It is for this reason that therapeutic manipulation of gut microbiota with fecal microbiota transplant is being explored as a potential treatment option for UC. FMT has demonstrated promise for ulcerative colitis, however little is known about the specific microbiota strains contributing to this observed improvement. In this study, the authors aimed to better understand the mechanisms and the specific strains in FMT contributing to this observed improvement, which is an important step toward improving efficacy and minimizing the risk of adverse events related to FMT in the future.”

Dr. Berinstein was surprised that O. splanchnicus was the only microbe identified that correlated with clinical response. “Previous studies have suggested that microbial diversity is a key factor in successful response to FMT,” he noted. “FMT remains an important potential nonpharmacologic treatment strategy for ulcerative colitis, however more research is needed to understand the mechanism and to develop safer and more efficacious methods for delivering FMT.” Specifically, prospective studies are needed to explore the efficacy and safety of FMT enriched in strains of O. splanchnicus to confirm the current study findings.

The current study is important at this time because, although microbial transferability has emerged as a potential to treat IBD, “the mechanistic understanding of microbial transferability and engraftment has been lacking,” Atsushi Sakuraba, MD, PhD of the University of Chicago, said in an interview. “I was surprised that the effectiveness of FMT in UC could be narrowed down to O. splanchnicus.” The current take-home message for clinicians is that, although FMT currently uses crude donor fecal material, it may soon use more selected microbial strains. However, “whether transfer of O. splanchnicus alone or enriched fecal material provide improved efficacy and safety need to be analyzed,” he added.

The study was supported by Boehringer Ingelheim, the National Institutes of Health, the Kenneth Rainin Foundation, and the Charina Foundation. One coauthor disclosed grant support from Boehringer Ingelheim for this study, and several coauthors are employees of Boehringer Ingelheim. Neither Dr. Berinstein nor Dr. Sakuraba had no financial conflicts to disclose.

Higher poverty concentration at the county level significantly increased the risk of firearm-related deaths in children and youth aged 5-24 years in the United States, based on a review of approximately 67,000 fatalities.

Firearms are the second-leading cause of death in children and young adults in the United States, according to data from the Centers for Disease Control and Prevention, wrote Jefferson T. Barrett, MD, of The Children’s Hospital at Montefiore, New York, and colleagues. County-level poverty has been associated with increased injury mortality in children, but the association between county-level poverty and firearm-related mortality in particular has not been well studied.

In a cross-sectional study published in JAMA Pediatrics, 67,905 firearm-related deaths in children and youth aged 5-24 years that occurred between Jan. 1, 2007, and Dec. 31, 2016 were analyzed. The deaths included 42,512 homicides (62.6%), 23,034 suicides (33.9%), and 1,627 unintentional deaths (2.4%).

County poverty data were acquired from the U.S. Census Bureau. County-level poverty was divided into five categories based on percentage of the population living below the federal poverty level: 0%-4.9%, 5%-9.9%, 10%-14.9%, 15%-19.9%, and 20% or more.

Overall, 88.6% of the total deaths were in males. Notably, 44.8% of total firearm-related deaths and 63.9% of homicides occurred in non-Hispanic Blacks, who make up only 14% of the youth population in the United States, the researchers wrote.

The total number of firearm-related deaths was 248 in the lowest quintile of poverty concentration, followed by 6,841, 18,551, 27,305, and 14,960 in the remaining quintiles.

In a multivariate regression model that included demographics, urban versus rural, and statewide firearm prevalence, youth in counties with the highest quintile of poverty concentration had an increased rate of total firearm-related deaths (adjusted incidence rate ratio, 2.29), as well as increased rates of homicides, suicides, and unintentional deaths (aIRR, 3.55, 1.45, and 9.32, respectively), compared with those living in the lowest quintile of poverty concentration. Individuals in the highest poverty quintile accounted for 22.0% of total firearm-related deaths, 25.5% of homicides, 15.3% of suicides, and 25.1% of unintentional deaths.

The researchers also calculated the population-attributable fraction (PAF) and years of potential life lost. “The PAF represents the proportion of deaths associated with a particular exposure, which was concentrated county poverty in this study,” they explained. The PAF for all firearm-related deaths was 0.51, PAFs for homicides, suicides, and unintentional deaths were 0.66, 0.30, and 0.86, respectively. The PAF calculation translated to 34,292 firearm-related deaths that may not have occurred if youth in all counties had the same risk as those in counties with the lowest poverty concentration.

“Over the 10-year study period, we observed 3,833,105 years of potential life lost in youth aged 5-24 years from firearm-related deaths,” the researchers wrote.

The study findings were limited by several factors including the potential bias of a cross-section design, and inability to account for all the ways that county-level poverty might increase the risk of firearm-related death in children and teens, the researchers noted. Other potential limitations include possible misclassification of death, lack of data on individual family incomes, shifts in counties in the poverty categories over time, and the use of statewide, rather than countywide, estimates of firearm ownership.

However, the results are consistent with those of previous studies, and add that “mortality rates were consistent even after controlling for demographic variables, county urbanicity, and statewide firearm prevalence,” the researchers concluded.
 

Address structural racism to reduce disparities

“Firearm-related homicides among youth aged 5-24 years are among the causes of death with the greatest disparities,” based on CDC fatal injury reports, wrote Alice M. Ellyson, PhD, Frederick P. Rivara, MD, and Ali Rowhani-Rahbar, MD, all of the University of Washington, Seattle, in an accompanying editorial.

The current study builds on previous research, including studies showing an association between income inequality and firearm-related homicide, they said. More research is needed to determine how to intervene in the pathways between poverty and firearm-related death. For example, if access to high-quality health care is a factor, programs to increase access to health insurance, such as the Affordable Care Act and Children’s Health Insurance Program, or to increase access to high-quality trauma care may help reduce firearm-related death in youth.

“The study of where, how, and why racism operates as a factor in both poverty and firearm-related death must continue, especially considering the disparities consistently documented in Alaska Native or American Indian, Black, and Hispanic communities,” the editorialists wrote.

“Key potential mechanisms for reducing the consequences of poverty for firearm-related death are often denied to racial and ethnic minority groups through a variety of structures, policies, and systems in health care, employment, housing, transportation, and education,” they emphasized, and the impact of racism, not only on the pathways to poverty, but also on mediators between poverty and firearm-related death, must be explored.

Findings spotlight need to for poverty programs

The study was an interesting look at the specific relationship between poverty and firearm-related deaths in people aged younger than 25 years in the United States, Tim Joos, MD, of Seattle said in an interview.

“Although America is not a poor country, the combination of poverty within America and its unique gun culture seems to prove deadly for its youth,” Dr. Joos said. “The strongest relationship is between firearm-related homicide and poverty, but unintentional firearm deaths and poverty also are clearly linked, whereas the link between firearm-related suicide and poverty appears to be present, but small.”.

In the current study, “the authors note that firearm deaths are the second-leading cause of death among all people ages 15-24 years,” said Dr. Joos. “Many of us have followed children from infancy just to have them meet this untimely end as adolescents, wishing we had a vaccine or other remedy in our toolbelt for this particular scourge.

“As our country currently debates the size of the social safety net, this study is one of many that suggests government programs aimed at poverty alleviation would substantially contribute to the health of American youth,” Dr. Joos added.

The study received no outside funding. Lead author Dr. Barrett had no financial conflicts to disclose. Dr. Ellyson disclosed funds from the CDC, the state of Washington, and the Grandmothers Against Gun Violence Foundation for research outside the submitted work. Dr. Rivara disclosed funds from the National Institutes of Health, the State of Washington, and the National Collaborative on Gun Violence Research for research outside the submitted work.

Other potential limitations include possible misclassification of death, lack of data on individual family incomes, shifts in counties in the poverty categories over time, and the use of statewide, rather than countywide, estimates of firearm ownership.

However, the results are consistent with those of previous studies, and add that “mortality rates were consistent even after controlling for demographic variables, county urbanicity, and statewide firearm prevalence,” the researchers concluded.
 

Address structural racism to reduce disparities

“Firearm-related homicides among youth aged 5-24 years are among the causes of death with the greatest disparities,” based on CDC fatal injury reports, wrote Alice M. Ellyson, PhD, Frederick P. Rivara, MD, and Ali Rowhani-Rahbar, MD, all of the University of Washington, Seattle, in an accompanying editorial.

The current study builds on previous research, including studies showing an association between income inequality and firearm-related homicide, they said. More research is needed to determine how to intervene in the pathways between poverty and firearm-related death. For example, if access to high-quality health care is a factor, programs to increase access to health insurance, such as the Affordable Care Act and Children’s Health Insurance Program, or to increase access to high-quality trauma care may help reduce firearm-related death in youth.

“The study of where, how, and why racism operates as a factor in both poverty and firearm-related death must continue, especially considering the disparities consistently documented in Alaska Native or American Indian, Black, and Hispanic communities,” the editorialists wrote.

“Key potential mechanisms for reducing the consequences of poverty for firearm-related death are often denied to racial and ethnic minority groups through a variety of structures, policies, and systems in health care, employment, housing, transportation, and education,” they emphasized, and the impact of racism, not only on the pathways to poverty, but also on mediators between poverty and firearm-related death, must be explored.

Findings spotlight need to for poverty programs

The study was an interesting look at the specific relationship between poverty and firearm-related deaths in people aged younger than 25 years in the United States, Tim Joos, MD, of Seattle said in an interview.

“Although America is not a poor country, the combination of poverty within America and its unique gun culture seems to prove deadly for its youth,” Dr. Joos said. “The strongest relationship is between firearm-related homicide and poverty, but unintentional firearm deaths and poverty also are clearly linked, whereas the link between firearm-related suicide and poverty appears to be present, but small.”.

In the current study, “the authors note that firearm deaths are the second-leading cause of death among all people ages 15-24 years,” said Dr. Joos. “Many of us have followed children from infancy just to have them meet this untimely end as adolescents, wishing we had a vaccine or other remedy in our toolbelt for this particular scourge.

“As our country currently debates the size of the social safety net, this study is one of many that suggests government programs aimed at poverty alleviation would substantially contribute to the health of American youth,” Dr. Joos added.

The study received no outside funding. Lead author Dr. Barrett had no financial conflicts to disclose. Dr. Ellyson disclosed funds from the CDC, the state of Washington, and the Grandmothers Against Gun Violence Foundation for research outside the submitted work. Dr. Rivara disclosed funds from the National Institutes of Health, the State of Washington, and the National Collaborative on Gun Violence Research for research outside the submitted work. Dr. Rowhani-Rahbar disclosed funds from the CDC, National Institutes of Health, National Collaborative on Gun Violence Research, Fund for a Safer Future, and state of Washington for research outside the submitted work. Dr. Joos had no financial conflicts to disclose, but serves on the editorial advisory board of Pediatric News.

The negative emotions stemming from teens’ involvement with social media have been grabbing the headlines. But adults may also be experiencing depression because of their use of social media, suggests a new study.

Use of social media has been linked to increased anxiety and depression, as well as reduced well-being in adolescents and young adults, but similar associations in older adults have not been well studied, and longitudinal data are lacking, Ron H. Perlis, MD, of Massachusetts General Hospital, Boston, and colleagues wrote in their paper, which was published in JAMA Network Open.

To examine the association between social media use and depressive symptoms in older adults, the researchers reviewed data from 13 waves of an internet survey conducted each month between May 2020 and May 2021. The survey respondents included individuals aged 18 years and older, with a mean age of 56 years.

In the study the researchers analyzed responses from 5,395 individuals aged 18 years and older, with a mean age of 56 years. The study participants had minimal or no depressive symptoms at baseline, according to scores on the nine-item Patient Health Questionnaire (PHQ-9).

Overall, 8.9% of the respondents reported a worsening of 5 points or more on the PHQ-9 score on a follow-up survey, which was the primary outcome. Participants who reported using social media platforms Snapchat, Facebook, or TikTok were significantly more likely to report increased depressive symptoms, compared with those who did not report use of social media. The fully adjusted odds ratio was largest for Snapchat (aOR, 1.53), followed by Facebook (aOR, 1.42), and TikTok (aOR, 1.39).

Incorporating recent television and internet news terms, such as COVID-19, changed the association for Snapchat, for which the aOR decreased from 1.53 to 1.12 when news source terms were included in the survey. TikTok and Facebook associations remained similar.

When the results were further stratified by age, use of TikTok and Snapchat was associated with depressive symptoms in those aged 35 years and older, but not in those younger than 35 years. However, the opposite pattern emerged for Facebook; use was associated with depressive symptoms for individuals younger than 35 years, but not in those aged 35 years and older (aOR, 2.60 vs. aOR, 1.12).

The association between increased self-reported depressive symptoms and use of certain social media platforms was not impacted by baseline social support or face-to-face interactions, the researchers noted.
 

Family physician was surprised results weren’t more significant

In the current study, “I was honestly surprised the results weren’t more significant,” Mary Ann Dakkak, MD, of Boston University said in an interview. “That said, social media uses during the COVID pandemic may have been a necessary social outlet and form of connection for many people who were otherwise isolated.”

To still see a significant increase in depression when social media could have been a positive force may suggest a heavier impact during “normal” times, she added.

“It is not surprising that what we see in youth is shown among adults,” noted Dr. Dakkak, who was not involved with this study. “I always tell my patients that what is good for their children is good for the adults too, and vice versa.

“We expect to see outcomes of this on youth and adults who have been more isolated, who have used more screen time for learning, work, connection and boredom, in the near future,” she said. “The complex nature of why social media may have been used more heavily for connection during a time when in-person meetings were not possible may be a heavy confounder as the typical profile of heavy social media users may have differed during the COVID shutdowns.”
 

Psychiatrist: Balance benefits of social media with mental health risks

The current study was likely conducted before the recent news on “hidden” Facebook data and the implications that Facebook knew it was contributing to worsened mental health in teens, particularly around self-esteem, Jessica “Jessi” Gold, MD, a psychiatrist at Washington University, St. Louis, said in an interview.

“If you look more specifically at other studies, however, the data around social media and mental health is constantly varied, with some showing benefits and some showing negatives, and none conclusively suggesting either way,” said Dr. Gold, who also was not involved with the new research. “More data are needed, especially longitudinally and on a broader age group, to understand social media’s impact on mental health over time.

“It is also even more important in the wake of COVID-19, as so many people have turned to social media as a primary source of social support and connection, and are using it even more than before,” she emphasized.

In the current study, “I think the most interesting information is that, for TikTok and Snapchat, the effects seemed to be more pronounced in those older than 35 years who used social media,” said Dr. Gold.

What this study leaves unanswered is “whether people who might develop depression are simply more prone to use social media in the first place, such as to seek out social support,” Dr. Gold said. “Also, we don’t know anything about how long they are using social media or what they are using it for, which to me is important for understanding more about the nuance of the relationship with mental health and social media.”
 

Experts advise clinicians to discuss social media with patients

This new research suggests that clinicians should be talking to their patients about how social media impacts their emotional reactions, as well as their sleep, Dr. Gold said.

“Patients should be asking themselves how they are feeling when they are on social media and not using it before sleep. They should also be considering time limits and how to effectively use social media while taking care of their mental health,” she said. This conversation between clinician and patient should be had with any patient of any age, who uses social media, not only with teenagers.

“This is also a conversation about moderation, and knowing that individuals may feel they benefit from social media, that they should balance these benefits with potential mental health risks,” she said.

“Studies such as this one shed light onto why social media consumption should be at least a point of discussion with our patients,” said Dr. Dakkak.

She advised clinicians to ask and listen to patients and their families when it comes to screen time habits. “Whenever I see a patient with mood symptoms, I ask about their habits – eating, sleeping, socializing, screen time – including phone time. I ask about the family dynamics around screen time.

“I’ve added screen time to my adolescent assessment. Discussing safe use of cell phones and social media can have a significant impact on adolescent behavior and wellbeing, and parents are very thankful for the help,” she said. “This study encourages us to add screen time to the assessments we do at all adult ages, especially if mood symptoms exist,” Dr. Dakkak emphasized.
 

Suggestions for future research

Dr. Dakkak added that more areas for research include the differences in the impact of social media use on content creators versus content consumers. Also, “I would like to see research using the real data of use, the times of use, interruptions in sleep and use, possible confounding variables to include exercise, presence of intimate relationship and school/job performance.”

Given the many confounding variables, more controlled studies are needed to examine mental health outcomes in use, how long people use social media, and the impact of interventions such as time limits, Dr. Gold said.

“We can’t ignore the benefits of social media, such as helping those with social anxiety, finding peer support, and normalizing mental health, and those factors need to be studied and measured more effectively as well, she said.
 

Take-home message

It is important to recognize that the current study represents a correlation, not causality, said Dr. Gold. In addressing the issues of how social media impact mental health, “as always, the hardest thing is that many people get their news from social media, and often get social support from social media, so there has to be a balance of not removing social media completely, but of helping people see how it affects their mental health and how to find balance.”

The study findings were limited by several factors, including the inability to control for all potential confounders, the inability to assess the nature of social media use, and the lack of dose-response data, the researchers noted. Although the surveys in the current study were not specific to COVID-19, the effects of social media on depression may be specific to the content, and the findings may not generalize beyond the COVID-19 pandemic period.

Approximately two-thirds (66%) of the study participants identified as female, and 76% as White; 11% as Black; 6% as Asian; 5% as Hispanic; and 2% as American Indian or Alaska Native, Pacific Islander or Native Hawaiian, or other.

The National Institute of Mental Health provided a grant for the study to Dr. Pelis, who disclosed consulting fees from various companies and equity in Psy Therapeutics. The study’s lead author also serves as associate editor for JAMA Network Open, but was not involved in the decision process for publication of this study. Dr. Gold disclosed conducting a conference for Johnson & Johnson about social media and health care workers, and was on the advisory council.

A study on the role of the ocular surface microbiome in rosacea pathogenesis and an investigation of elevated intracellular signals in rosacea lesions earned new research funding from the National Rosacea Society (NRS) this year, as part of the organization’s research grants program.

National Rosacea Society

The NRS research grants program was created to increase knowledge and understanding of not only the potential causes of rosacea, but other aspects of the disease that may inform prevention, treatment, or a potential cure, according to the press release announcing the recipients.

New research grant recipient Sezen Karakus, MD, of the Johns Hopkins Wilmer Eye Institute, Baltimore, received $15,000 for a study on the contribution of the ocular surface microbiome to the development of rosacea. Ocular rosacea can result in corneal complications severe enough to affect vision, and identifying the microorganisms on the ocular surface may lead to new treatment strategies, Dr. Karakus said in the release. He will collaborate on this research with dermatologist Noori Kim, MD, of Johns Hopkins University, Baltimore.

A second new research grant went to Emmanuel Contassot, MD, project leader in the dermatology department at of the University Hospital of Basel, Switzerland, who received $5,000 to investigate whether certain elevated intracellular signals in rosacea lesions may promote the skin inflammation that may be a root cause of the condition.

The NRS also renewed its support of a pair of ongoing studies. Michelle Trautwein, MD, of the Institute for Biodiversity Science and Sustainability at the California Academy of Sciences, continues her work on the first study to sequence the genome of Demodex mites; the study also identifies associated bacteria that may play a role in rosacea.

Michelle Trautwein, MD, of the Institute for Biodiversity Science and Sustainability at the California Academy of Sciences, continues her work on the first study to sequence the genome of Demodex mites; the study also identifies associated bacteria that may play a role in rosacea.

Treatment with intravenous ferric carboxymaltose significantly improved symptoms in restless legs syndrome (RLS) patients with iron-deficiency anemia (IDA), data from 29 adults show.

RLS occurs among individuals with normal iron but is at least six times higher among individuals with IDA, Hyoeun Bae, MD, of Keimyung University, Daegu, South Korea, and colleagues wrote. Previous studies have explored iron treatments for RLS patients with IDA, however, guidelines for treatment have not yet been published.

In a study published in Sleep Medicine, the researchers randomized 29 RLS patients with IDA to either 1,500 mg IV ferric carboxymaltose (FCM) or placebo for a short-term period of 6 weeks, followed by a phase 2 study for responders that lasted for 52 weeks. Baseline characteristics, including age, gender, iron parameters, and sleep and mood scales were similar between the groups.

At 6 weeks, patients in the FCM group showed significant improvement in RLS symptom severity based on changes from baseline International Restless Legs Syndrome Study Group scale (IRLS) scores, compared with placebo patients (–13.47 vs. 1.36, P < .001). A secondary outcome of sleep quality also improved significantly in the FCM group, compared with the placebo group.

After 6 weeks, 11 of the 14 patients in the placebo group also received 1,500 mg FCM for an open-label study. These patients also showed significant improvement in IRLS scores from baseline to 6 weeks.

All 23 responders from the short-term studies (13 who received FCM initially and 10 from the postplacebo group) enrolled in a phase 2 long-term study that lasted for 52 weeks; 14 of these completed the full 52-week study period.

Overall, 61% of participants in phase 2 of the study remained off their RLS medications at 52 weeks, and no serious adverse events were reported during the study period. Of these, 10 received one additional dose of FCM and 4 received more than one additional dose. The median change in IRLS score at 4 weeks after treatment was –4.00, compared with the score prior to treatment.

The study is the first of its design to show benefits of intravenous iron therapy for RLS in patients with IDA, the researchers said, noting that the findings of improved, but not cured, RLS symptoms might suggest that more than 1,500 mg of iron is needed to fully treat RLS in this patient population. “A second interpretation is that the RLS and IDA were separate events: a patient with idiopathic RLS who subsequently developed anemia,” they said. “Treating the IDA might improve symptoms but may not eliminate the symptoms.”

The study findings were limited by several factors, including the relatively small study population and inability to know the time frame for the development of IDA, the researchers noted. However, the results support the use of intravenous iron therapy for relief of RLS in IDA patients.

“Since IDA could result in epigenetic changes leading to irreversible state of RLS, then urgent and adequate management of the IDA in RLS patients would seem a very prudent and important clinical approach to this specific clinical condition,” they concluded.

The study received no outside funding. The researchers had no disclosures.

Use of a transdermal blonanserin patch significantly improved extrapyramidal symptoms (EPS), compared with oral blonanserin tablets in patients with schizophrenia, according to results of an open-label study of 155 adults.

Blonanserin, a second-generation antipsychotic, has been shown to reduce extrapyramidal symptoms when used to treat schizophrenia, but the impact of switching to a patch on extrapyramidal symptoms and on the use of antiparkinson drugs has not been well studied, Kazutaka Ohi, MD, of Gifu University Graduate School of Medicine, Seki, Japan, and colleagues wrote. Advantages of the patch include the ability to provide stable blood concentrations and the ability to be concealed under clothing to avoid patients’ embarrassment at taking oral medications.

In a study published in Progress in Neuropsychopharmacology & Biological Psychiatry, the researchers identified 155 adults aged 18 years and older diagnosed with schizophrenia who were treated at 37 medical institutions in Japan between February 2015 and May 2017.

The first cohort of 97 patients received blonanserin tablets (8-16 mg/day) for 6 weeks, followed by blonanserin transdermal patches (40-80 mg/day) once daily for 1 year. The second cohort of 58 patients received continuous blonanserin patch therapy. Extrapyramidal symptoms were assessed using the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS); individual scores ranged from a 0 for normal to a 4 for severe.

Overall, DIEPSS scores decreased significantly in both cohorts after switching from blonanserin tablets or powders to transdermal patches. The average DIEPSS change from baseline at 3, 6, and 12 months was –0.44, –0.07, and –0.14, respectively, in cohort 1, and –0.16, –0.74, and –0.81, respectively, in cohort 2.

The researchers also assessed the impact of transition to transdermal patches on the use of antiparkinsonism drugs using the biperiden equivalents of total antiparkinsonian drugs (BPD-eq) measure. At baseline, about 22% of patients used concomitant antiparkinsonism drugs, compared with 25.8% at 1 year after starting patch treatment. The dose of antiparkinson drugs was not significantly decreased after switching to transdermal patches, in part because of psychiatrists’ prescribing behaviors, Dr. Ohi and colleagues noted.

As a secondary outcome, the researchers examined psychotic symptoms and found that Positive and Negative Syndrome Scale (PANSS) negative symptom scores decreased significantly in patients in cohort 1 who switched from tablets or powders to patches. Changes in scores from baseline to 3, 6, and 12 months were –0.7, –1.0, and –1.3, respectively. Positive PANSS scores did not change significantly in cohort 1. In cohort 2, both positive and negative PANSS scores decreased significantly over 12 months after switching from blonanserin tablets/powders to patches. The mean changes in scores from baseline to 3, 6, and 12 months were –1.6, –2.3, and –2.4, respectively, for PANSS positive symptom scores, and –1.4, –2.7, and –2.8, respectively, for negative symptom scores.

A total of 41.2% of cohort 1 patients and 44.8% of cohort 2 patients discontinued patch treatments by 1 year. Four patients discontinued the patch because of EPS during the treatment period in cohort 1; no patients in cohort 2 discontinued because of EPS.

The study findings were limited by several factors, including the open-label design and lack of controls; also, the study did not examine crossover changes in patients who switched from tablets or powders to patches, the researchers noted.

However, the results indicate that direct switching from blonanserin tablets or powders to transdermal patches reduced EPS and psychotic symptoms in schizophrenia and may be more acceptable to patients, compared with oral medications, as well as more effective, they concluded.

The study received no outside funding, and Dr. Ohi and colleagues had no disclosures.

Women with a history of stage III to stage IV breast cancer had significantly more pathologic vertebral fractures compared to those with stage I and stage II disease, based on data from approximately 5,000 adult women.

Breast cancer remains associated with increased fracture risk in part because of estrogen deficiency, aromatase inhibitors, frailty, and skeletal metastases, wrote Joan C. Lo, MD, of Kaiser Permanente Northern California, Oakland, and colleagues. Fractures associated with these factors have been studied, but many of the existing epidemiologic studies lack detail on fractures related to cancer, they noted. The researchers examined the association between pathologic fractures and major osteoporotic fractures in women with invasive breast cancer who received endocrine therapy.

In a study published in JAMA Network Open (2021 Nov 18. doi: 10.1001/jamanetworkopen.2021.33861), the researchers reviewed data from 5,010 women enrolled in the Pathways Study (3,312 women) or Research Program on Genes, Environment, and Health (RPGEH) study (1,698 women) with newly diagnosed invasive breast cancer who received endocrine therapy. The women were followed for up to 10 years for incident fracture, with a median follow-up period of 6.7 years.

The average age of the women was 60.2 years; 73.3% were non-Hispanic White, 4.9% were Black, 9.4% were Hispanic, and 1.6% were women whose ethnicity was unknown. Approximately 90% of the women were at stage I to stage II at initial diagnosis.

Overall, 340 (6.8%) had incident fractures during the follow-up period. The incident fractures included 46 hip, 104 vertebral, 78 humerus, and 137 wrist fractures. Significantly more women with hip fracture (43.5%) were age 80 years or older, compared with less than 25% of women with vertebral fractures (22.1%), humerus (19.2%), or wrist fracture (15.3%).

Pathologic fractures accounted for 22 of 104 incident vertebral fractures (21.2%) and fewer than 5 of 46 incident hip fractures (8.7%); few wrist and humerus fractures were pathologic. According to tumor stage, 15 of 87 (17.2%) vertebral fractures in women with initial stage I and II were pathologic, compared to 7 of 17 (41.2%) in women with initial stage III to stage IV breast cancer (P < .05).

The results emphasized the need to consider vertebral fracture risk in women with breast cancer, notably advanced stage cancer, as approximately one-third of the incident vertebral fractures in this subset of patients was deemed cancer-related, the researchers noted.

“As the axial skeleton is a common site for breast cancer metastasis and vertebrae a common site for pathologic fracture, primary care physicians should consider the possibility of pathologic fracture in women with higher risk based on advanced-stage cancer history,” the researchers wrote.

The study findings were limited by several factors, including the lack of data on fracture risk factors, treatment, and chemotherapy, and the inclusion only of clinically diagnosed fractures and not asymptomatic vertebral fractures, the researchers noted. However, the results were strengthened by the large sample size and comprehensive fracture assessment, they said. Additional studies to examine nonpathologic fracture risk according to breast cancer treatment, such as the use of aromatase inhibitors versus cytotoxic chemotherapy, may inform which women would benefit from more aggressive osteoporotic fracture prevention, they concluded.
 

Findings inform shared decision-making

“This study highlights the apparent association between an initial diagnosis of stage III or IV breast cancer and an increased risk for pathologic vertebral fracture,” said Constance Bohon, MD, a gynecologist in private practice in Washington, D.C., in an interview. “Most likely this finding is secondary to breast cancer metastases,” Dr. Bohon noted. However, she questioned whether there is a difference in fracture rates between women who received only aromatase inhibitors, those who received tamoxifen, and those who received both treatments.

“Additional data to determine the age of menopause, exercise frequency, current weight, and family history of osteoporosis may serve to identify those at highest risk for pathologic vertebral fracture,” said Dr. Bohon. “Until further data are available, clinicians should review this study and counsel their patients regarding options to potentially mitigate their apparent increased risk for pathologic vertebral fracture,” she emphasized.

The study was supported by the National Cancer Institute, National Institutes of Health, and the Research Program on Genes, Environment, and Health of Kaiser Permanente Northern California. The researchers had no financial conflicts to disclose. Dr. Bohon had no financial conflicts to disclose but serves on the Editorial Advisory Board of Ob.Gyn. News.

Findings inform shared decision-making

“This study highlights the apparent association between an initial diagnosis of stage III or IV breast cancer and an increased risk for pathologic vertebral fracture,” said Constance Bohon, MD, a gynecologist in private practice in Washington, D.C., in an interview. “Most likely this finding is secondary to breast cancer metastases,” Dr. Bohon noted. However, she questioned whether there is a difference in fracture rates between women who received only aromatase inhibitors, those who received tamoxifen, and those who received both treatments.

“Additional data to determine the age of menopause, exercise frequency, current weight, and family history of osteoporosis may serve to identify those at highest risk for pathologic vertebral fracture,” said Dr. Bohon. “Until further data are available, clinicians should review this study and counsel their patients regarding options to potentially mitigate their apparent increased risk for pathologic vertebral fracture,” she emphasized.

The study was supported by the National Cancer Institute, National Institutes of Health, and the Research Program on Genes, Environment, and Health of Kaiser Permanente Northern California.

A majority of healthy preschoolers were able to recognize emotions shown in static pictures of adults with and without face masks, based on data from a cross-sectional study of 276 children.

Some are concerned about the effects of adults working in preschools wearing face masks on the ability of young children to learn to recognize emotions, study author Juliane Schneider, MD, of University Hospital Lausanne (Switzerland), and colleagues wrote. Previous studies using photographs of faces with digitally added masks have suggested that young children’s emotional recognition was worse with masked faces.

In the study published in JAMA Pediatrics, the researchers tested the impact of masks on the ability of preschool children to identify joy, anger, and sadness. The study included 135 girls and 141 boys aged 36-72 months with a mean age of 52.4 months. The tests were conducted at nine daycare centers.

Children were shown photographs of 15 actors (5 men and 10 women) with and without surgical face masks. The total data set included 90 pictures illustrating joy, anger, and sadness. The children were shown the pictures at random, and they could either name the emotion, point to a card with emoticons showing the three emotions, or respond “I don’t know” or “quit the experiment.” Test sessions lasted approximately 7 minutes per child. Effect sizes were calculated using X² and Cramer V tests.

Overall, 68.8% of the children correctly identified the emotion portrayed; the correct response rate was 70.6% for faces without face masks and 66.9% for those with face masks. Correct recognition of joy was significantly higher for faces without masks than for those with masks (94.8% vs. 87.3), as was correct recognition of sadness (54.1% vs. 48.9%; P < .001 for both). Recognition of anger was not significantly different for unmasked and masked faces (62.2% vs. 64.6%, P = .10).

No significant differences in correct responses appeared between boys and girls and the rate of correct responses increased significantly with age. The rates of “I don’t know,” and “quit the experiment” responses were 3.1% and 2.2%, respectively. In an analysis of incorrect responses, approximately 25% of the children confused anger and sadness, and 21% misidentified joy for images of anger or sadness.

“Overall, participants in this study, who had been exposed to face masks for nearly a year, recognized emotions on pictures better than has been reported in previous research, even with face masks,” the researchers wrote.

The study findings were limited by several factors including the use of static pictures versus real individuals, which limits generalizability, and the lack of data on children with developmental issues, the researchers noted.

Despite relatively small differences and weak effect size (Cramer V scores of 0.2 or less for all), the results show a stronger recognition of emotion, compared with other studies, and highlight the importance of investigating the impact of face masks on other aspects of child development as the COVID-19 pandemic persists, the researchers concluded.

The study received no outside funding. The researchers had no relevant financial conflicts to disclose.

Reducing the dose of tumor necrosis factor inhibitors by approximately one-third did not increase disease activity in adults with psoriatic arthritis (PsA) or axial spondyloarthritis (axSpA) in a stable low–disease activity state, according to findings from two parallel controlled retrospective cohort studies.

Disease activity–guided dose optimization (DAGDO) can reduce drug exposure in patients with PsA or axSpA who have low disease activity, but its impact on increased disease activity has not been as well studied as full-dose continuation, Celia A.J. Michielsens, MD, of Sint Maartenskliniek, Nijmegen, the Netherlands, and colleagues wrote.

“DAGDO or discontinuation of bDMARDs [biologic disease-modifying antirheumatic drugs] as a standard of care in adults with stable axSpA is currently discouraged by” the American College of Rheumatology, the researchers said. However, guidelines from the European Alliance of Associations for Rheumatology allow for the slow tapering of bDMARDs in patients with sustained remission.

In a controlled, retrospective cohort study published in Rheumatology, the researchers analyzed data from their outpatient clinic, which initiated a specific TNF inhibitor DAGDO protocol in 2010 for patients with RA, PsA, and axSpA. Disease activity was measured using the Disease Activity Score in 28 joints with C-reactive protein (DAS28-CRP) for patients with PsA and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) for patients with axSpA.

The study population included 153 patients with PsA who had a mean DAS28-CRP of 6.5 and 171 with axSpA who had a similar mean number of disease activity measurements (6.5 with DAS28-CRP and 6.4 with BASDAI). Median follow-up time was several months short of 4 years in each group. Treatment was divided into three periods: continuation of full TNF inhibitor dose, TNF inhibitor DAGDO, and a period with stable TNF inhibitor dose after DAGDO.

Overall, no significant differences appeared in mean DAS28-CRP and BASDAI over the course of the study between the period of the full TNF inhibitor dose continuation and both the TNF inhibitor DAGDO period and the stable TNF inhibitor dose period. Among PsA patients, the mean DAS28-CRP was 1.94 for the full-dose period, 2.0 in the TNF inhibitor DAGDO period, and 1.97 in the stable TNF inhibitor dose after DAGDO period. For axSpA patients, the mean BASDAI was 3.44, 3.47, and 3.48, respectively, for the three periods. Older age, longer disease duration, and longer follow-up were significantly associated with higher DAS28-CRP scores in patients with PsA, and older age and female gender were significantly associated with higher BASDAI scores in patients with axSpA.

The mean percentage of daily defined dose (%DDD) for patients with PsA was 108% during the full dose period, 62% in the TNF inhibitor DAGDO period, and 78% with stable TNF inhibitor after DAGDO, and nearly the same for patients with axSPA at 108%, 62%, and 72%, respectively.

The %DDD represents “a modest degree of tapering,” compared with studies in RA patients, the researchers noted. “Explanations for this difference could be that the full dose-reduction potential was not met due to suboptimal execution of the local protocol, whereas in prospective intervention trials, protocol adherence is likely higher.”

The study findings were limited by several factors including the open-label design and potential for nocebo effects, possible incorrect attribution, and information bias, as well as the use of DAS28-CRP and BASDAI rather than more modern measurement tools, the researchers noted.

However, the results were strengthened by the large sample size and real-world clinical setting, frequent assessment of disease activity, long-term follow-up, and the performance of DAGDO by rheumatologists familiar with the measuring tools, they said. The results suggest that DAGDO is safe and effective for patients with low disease activity in either condition, but randomized, prospective studies can provide more definitive evidence.

The study received no outside funding. One author disclosed relationships with multiple pharmaceutical companies.

Chemical peels are an effective and well-tolerated field treatment for actinic keratoses (AKs), according to the authors of a systematic review of five studies including 88 patients.

AKs remain an ongoing health concern because of their potential to become malignant, and chemical peels are among the recommended options for field therapy, wrote Angela J. Jiang, MD, from the department of dermatology at the Henry Ford Health System, Detroit, and colleagues. “Although most dermatologists agree on the importance of field treatment, cryotherapy still remains the standard of care for treatment of AKs,” they noted, adding that the safety and efficacy of chemical peels for AK field therapy have not been well studied.

Chemical peels offer the benefit of a single treatment for patients, which eliminates the patient compliance issue needed for successful topical therapy, the researchers said. In fact, “patients report preference for the tolerability of treatment with chemical peels and the shorter downtime, compared with other field treatments,” they added.

In the study published in Dermatologic Surgery, they reviewed data from five prospective studies on the safety and efficacy of chemical peels as AK field treatments published from 1946 to March 2020 in the National Library of Medicine’s PubMed database. Of the 151 articles on the use of chemical peels for AKs, the 5 studies met the criteria for their review.

One split-face study evaluated glycolic acid peels (published in 1998), two split-face studies evaluated a combination of Jessner’s and 35% trichloroacetic acid (TCA) peels (published in 1995 and 1997), and two randomized studies evaluated TCA peels alone (published in 2006 and 2016).

Overall, the studies showed efficacy of peels in reducing AK counts, with minimal adverse events. In the glycolic acid study, 70% glycolic acid plus 5-fluorouracil (5-FU) yielded a 91.9% mean reduction in AKs at 6 months’ follow-up. A combination of Jessner’s solution and 35% TCA showed a significant reduction in AKs at 12 and at 32 months post treatment – a 75% reduction at 12 months in one study and 78% at 32 months in the other – similar to results achieved with 5-FU.

In studies of TCA alone, 30% TCA peels were similar in AK reduction (89%) to 5-FU (83%) and carbon dioxide laser resurfacing (92%). In another TCA study, 35% TCA was less effective at AK reduction at 12 months, compared with aminolevulinic acid photodynamic therapy (ALA-PDT), but the 35% peel was applied at a more superficial level than in the study of 30% TCA, the authors wrote.

Chemical peels also demonstrated effectiveness in preventing keratinocytic carcinomas, the researchers wrote. In the 30% TCA study, the rate of keratinocyte carcinoma development was 3.75-5.25 times lower in patients treated with 30% TCA peels, compared with 5-FU and carbon dioxide laser resurfacing (CO₂) after 5 years.

Chemical peels were well tolerated overall, although side effects varied among the studies. Patients in one study reported no side effects, while patients in other studies reported transient erythema and discomfort. In the study comparing TCA with PDT treatment, PDT was associated with greater pain, erythema, and pustules, the researchers wrote; however, patients treated with 35% TCA reported scarring.

From patients’ perspectives, chemical peels were preferable because of the single application, brief downtime, and minimal adverse effects. From the provider perspective, chemical peels are a more cost-effective way to treat large surface areas for AKs, compared with 5-FU or lasers, the researchers said.

The study findings were limited by several factors including the small number of prospective studies and relatively small number of patients, they noted. “The small number of included studies is partially due to the lack of studies that performed AK counts before and after treatments,” they said. The dearth of literature on chemical peels for AKs may stem from lack of residency training on the use of peels, they added.

However, the results support the use of chemical peels as an effective option for field treatment of AKs, with the added benefits of convenience and cost-effectiveness for patients, they concluded.

From the provider perspective, chemical peels are a more cost-effective way to treat large surface areas for AKs, compared with 5-FU or lasers, the researchers said.

The study findings were limited by several factors including the small number of prospective studies and relatively small number of patients, they noted. “The small number of included studies is partially due to the lack of studies that performed AK counts before and after treatments,” they said. The dearth of literature on chemical peels for AKs may stem from lack of residency training on the use of peels, they added.

However, the results support the use of chemical peels as an effective option for field treatment of AKs, with the added benefits of convenience and cost-effectiveness for patients, they concluded.

The study received no outside funding. The researchers had no financial conflicts to disclose.
