‘Exciting’: Post-SCT, antiviral T-cell therapy shows promise

Article Type
Changed

Posoleucel, an investigational off-the-shelf T-cell therapy, showed promising safety and efficacy for eradicating multiple viruses in a phase 2 study of patients who previously underwent allogeneic stem cell transplant (allo-SCT).

Of 58 adult and pediatric patients with a total of 70 viral infections at the time of enrollment in the open-label trial, 55 (95%) had a treatment response within 6 weeks of infusion with posoleucel, and the amount of circulating virus was reduced by an average of 97%, Thomas Pfeiffer, MD, and colleagues reported.

In 12 patients who had more than one viral infection, 10 (83%) had a response against each of the viruses, researchers noted.

The responses were defined as a reduction of viral load to normal range with complete response, or as a viral load reduction of at least 50 percent or a partial response.

The findings were published online in Clinical Cancer Research.

Specifically, the treatment evoked responses to adenovirus in 83% of 12 affected patients, BK virus in all 27 affected patients, CMV in 96% of 24 affected patients, Epstein-Barr virus in both affected patients, and human herpes virus in 75% of 4 patients. Additionally, one patient with JC virus experienced initial stabilization of viral symptoms, although the symptoms ultimately progressed, and the patient died.

“The key finding is that 95% of patients whose infections had been refractory to conventional therapies responded to posoleucel with corresponding reductions in viral load and with limited rates of GvHD [graft-versus-host disease],” Dr. Pfeiffer, a pediatric cancer specialist at Washington University in St. Louis, explained in a prepared statement. “Overall, posoleucel was found to be very effective and had a favorable safety profile in a highly vulnerable patient population.”

Dr. Bilal Omer

“Another exciting observation from this study was that posoleucel could be administered within 24 hours in some cases, with symptom resolution in a matter of days in some patients,” added senior author Bilal Omer, MD, a pediatric hematologist-oncologist at Texas Children’s Hospital and Baylor College of Medicine, Houston. “It was quite impressive how quickly patients could be treated.”

Dr. Omer explained that currently available treatments for patients who develop viral infections after allo-SCT have numerous limitations, including toxicities such as myelosuppression or kidney injury and limited efficacy.

In this study, 13 patients (22% percent) reported acute GvHD, but only 4 of the cases were considered de novo cases; 9 patients had been diagnosed with GvHD prior to posoleucel treatment. The most common GvHD symptoms were skin flares, which were successfully treated in the majority of cases, Dr. Omer explained.

No patients experienced cytokine release syndrome.

“The ability to target six viruses with a single therapy would be beneficial for patients with multiple viral infections,” he said, adding that posoleucel is the first T-cell therapy in development for BK virus, which can cause severe bladder infections.

Posoleucel utilizes healthy donor T cells rather than the patient’s or transplant donor’s T cells, which circumvents the lengthy development process of more customized therapies and allows for earlier treatment of viral infections, he noted.

The investigators are currently evaluating posoleucel in randomized phase 3 clinical trials to confirm these findings.

This study was supported by the National Heart, Lung, and Blood Institute Production Assistance for Cellular Therapies; Conquer Cancer Foundation/American Society for Clinical Oncology; the Dan L. Duncan Comprehensive Cancer Center; and the National Institutes of Health.

Dr. Omer disclosed pending patent applications for engineered T-cell therapies unrelated to this study, and he has received research funding from AlloVir, which manufactures posoleucel. Dr. Pfeiffer declared no conflicts of interest.

Frequent visits to green spaces linked to lower use of some meds

Article Type
Changed

Frequent visits to green spaces such as parks and community gardens are associated with a reduced use of certain prescription medications among city dwellers, a new analysis suggests.

In a cross-sectional cohort study, frequent green space visits were associated with less frequent use of psychotropic, antihypertensive, and asthma medications in urban environments.

Viewing green or so called “blue” spaces (views of lakes, rivers, or other water views) from the home was not associated with reduced medication use.

The growing scientific evidence supporting the health benefits of nature exposure is likely to increase the availability of high-quality green spaces in urban environments and promote the use of these spaces, lead author Anu W. Turunen, PhD, from the Finnish Institute for Health and Welfare, Kuopio, Finland, told this news organization.

This might be one way to improve health and well-being among city dwellers, Dr. Turunen added.

The findings were published online  in Occupational and Environmental Medicine.
 

Nature exposure a timely topic

Exposure to natural environments is thought to be beneficial for human health, but the evidence is inconsistent, Dr. Turunen said.

“The potential health benefits of nature exposure is a very timely topic in environmental epidemiology. Scientific evidence indicates that residential exposure to greenery and water bodies might be beneficial, especially for mental, cardiovascular, and respiratory health, but the findings are partly inconsistent and thus, more detailed information is needed,” she said.

In the current cross-sectional study, the investigators surveyed 16,000 residents of three urban areas in Finland – Helsinki, Espoo, and Vantaa – over the period of 12 months from 2015 to 2016, about their exposure to green and blue spaces.

Of this number, 43% responded, resulting in 7,321 participants.

In the questionnaire, green areas were defined as forests, parks, fields, meadows, boglands, and rocks, as well as any playgrounds or playing fields within those areas, and blue areas were defined as sea, lakes, and rivers. 

Residents were asked about their use of anxiolytics, hypnotics, antidepressants, antihypertensives, and asthma medication within the past 7 to 52 weeks.

They were also asked if they had any green and blue views from any of the windows of their home, and if so, how often did they look out of those windows, selecting “seldom” to “often.”

They were also asked about how much time they spent outdoors in green spaces during the months of May and September. If so, did they spend any of that time exercising? Options ranged from never to five or more times a week.

In addition, amounts of residential green and blue spaces located within a 1 km radius of the respondents’ homes were assessed from land use and land cover data.

Covariates included health behaviors, outdoor air pollution and noise, and socioeconomic status, including household income and educational attainment.

Results showed that the presence of green and blue spaces at home, and the amount of time spent viewing them, had no association with the use of the prescribed medicines.

However, greater frequency of green space visits was associated with lower odds of using the medications surveyed.

For psychotropic medications, the odds ratios were 0.67 (95% confidence interval, 0.55-0.82) for 3-4 times per week and 0.78 (95% CI, 0.63-0.96) for 5 or more times per week.

For antihypertensive meds, the ORs were 0.64 (95% CI, 0.52-0.78) for 3-4 times per week and 0.59 (95% CI, 0.48-0.74) for 5 or more times per week.

For asthma medications, the ORs were 0.74 (95% CI, 0.58-0.94) for 3-4 times per week and 0.76 (95% CI, 0.59-0.99) for 5 or more times per week.

The observed associations were attenuated by body mass index.

“We observed that those who reported visiting green spaces often had a slightly lower BMI than those who visited green spaces less often,” Dr. Turunen said. However, no consistent interactions with socioeconomic status indicators were observed.

“We are hoping to see new results from different countries and different settings,” she noted. “Longitudinal studies, especially, are needed. In epidemiology, a large body of consistent evidence is needed to draw strong conclusions and to make recommendations.”
 

 

 

Evidence mounts on the benefits of nature

There is growing evidence that exposure to nature could benefit human health, especially mental and cardiovascular health, says Jochem Klompmaker, PhD, a postdoctoral researcher in the department of environmental health at the Harvard T.H. Chan School of Public Health, Boston.

Dr. Klompmaker has researched the association between exposure to green spaces and health outcomes related to neurological diseases.

In a study recently published in JAMA Network Open, and reported by this news organization, Dr. Klompmaker and his team found that among a large cohort of about 6.7 million fee-for-service Medicare beneficiaries in the United States aged 65 or older, living in areas rich with greenery, parks, and waterways was associated with fewer hospitalizations for certain neurological disorders, including Parkinson’s disease, Alzheimer’s disease, and related dementias.

Commenting on the current study, Dr. Klompmaker noted its strengths.

“A particular strength of this study is that they used data about the amount of green and blue spaces around the residential addresses of the participants, data about green space visit frequency, and data about green and blue views from home. Most other studies only have data about the amount of green and blue spaces in general,” he said.

“The strong protective associations of frequency of green space visits make sense to me and indicate the importance of one’s actual nature exposure,” he added. “Like the results of our study, these results provide clinicians with more evidence of the importance of being close to nature and of encouraging patients to take more walks. If they live near a park, that could be a good place to be more physically active and reduce stress levels.”

The study was supported by the Academy of Finland and the Ministry of the Environment. Dr. Turunen and Dr. Klompmaker report no relevant financial relationships.

Genetic testing in the PICU prompts meaningful changes in care

Article Type
Changed

Two-thirds of children who underwent genetic testing in the pediatric intensive care unit showed a genetic variant, and a third of these children received changes in care as a result, according to a new study presented at the Society of Critical Care Medicine’s 2023 Critical Care Congress.

“We have had a lot of success using genome sequencing to help not only with diagnosis, but also changes in management,” lead author Katherine Rodriguez, MD, a pediatric critical care fellow physician at Rady Children’s Hospital, San Diego, told this news organization.

However, data on the use of rapid whole genome sequencing (rWGS) in the pediatric intensive care unit (PICU) are limited, and data from multiple institutions are lacking, Dr. Rodriguez said. In the current study, data from multiple hospitals allowed the researchers to examine differences in management across institutions, she said.

Dr. Rodriguez, with principal investigator Nicole Coufal, MD, also of Rady Children’s, and colleagues conducted the study at three children’s hospitals from March 2019 to July 2022. The study population included 80 children whose origin of illness was uncertain. The patients underwent rWGS testing in the PICU or cardiac ICU setting. The patients ranged in age from 0 to 17 years; 64% were younger than 1 year, (mean age, 2.8 years); 56% were male, and 59% were White.  

After rWGS testing, 65% of the children were positive for a genetic variant. The data prompted changes to care for 42% of these patients; 38% of the changes occurred during the patient’s PICU stay, including medication changes and procedures that were either avoided or completed.

The remaining 62% of the changes were subacute and affected management for the remainder of the child’s hospitalization and after discharge, Dr. Rodriguez explained in her presentation.

The average turnaround time for the testing was 10 days, which is important to an intensivist, who may have been hesitant to order tests because of the time involved, Dr. Rodriguez said. The current study shows that “we can get test results in a reasonable time to make meaningful changes in care,” she told this news organization.

Choosing which patients to test can be a challenge for clinicians, Dr. Rodriguez acknowledged. “We have gotten a sense of which patients are likely to have diagnostic or not diagnostic genomes, but it is also a gut feeling,” she said.

“If this child is your patient and you are concerned, if they seem sicker than expected, or have a concerning family history, then send the test,” she said. “It is becoming more affordable, and can come back quickly enough to guide treatment while the patient is still in the ICU.”

In the current study, the greatest diagnostic utility appeared in patients with cardiac symptoms, such as congenital heart disease, sudden cardiac arrest, or suspected channelopathy, Dr. Rodriguez said in her presentation.

Patients with suspected neurological disease had a 50% rate of molecular diagnosis. “Interestingly, 74% of patients with respiratory disease where an underlying genetic etiology was suspected received a molecular diagnosis,” although rWGS was not applied to general populations with RSV or other respiratory illnesses, she said.

In her presentation, Dr. Rodriguez shared examples of how genetic testing had a dramatic impact on patient survival. In one case, a 14-year-old girl presented in cardiac arrest and was found to have new-onset dilated cardiomyopathy. Whether the etiology was acquired or infectious and possibly reversible or genetic was unclear, she said.

“A diagnostic genome result within 48 hours indicated a genetic etiology,” she said. The patient was listed for heart transplant despite the incomplete infectious workup, and received a successful heart transplant 1 week after admission, Dr. Rodriguez said.

Guidelines for which PICU patients should undergo genetic testing do not yet exist, Dr. Rodriguez told this news organization. “We are trying to find some more meaningful parameters where we can say that a patient has a high pretest possibility of a genetic condition,” she said.

“Increasing availability of rWGS can significantly impact patient care and assist families in making difficult decisions during times of critical illness,” she said.

Insurance coverage and testing access are improving, said Dr. Rodriguez. Medicaid policies exist for neonates/infants in the ICU in several states, including Oregon, California, Michigan, Maryland, and Louisiana, she said. In some areas, hospitals may pay for testing for these children if insurance will not, she added.

Dr. Rodriguez and colleagues are continuing to enroll patients in a prospective study of the impact of rWGS, with the addition of a fourth study site and inclusion of family surveys. “We also will be looking at a secondary analysis of cost savings and benefits,” she said.

Ultimately, the current study should be empowering to physicians, “especially if they don’t have good access to geneticists,” Dr. Rodriguez said in an interview.

The study received no outside funding. Dr. Rodriguez reports no relevant financial relationships.

Two-thirds of children who underwent genetic testing in the pediatric intensive care unit showed a genetic variant, and a third of these children received changes in care as a result, according to a new study presented at the Society of Critical Care Medicine’s 2023 Critical Care Congress.

“We have had a lot of success using genome sequencing to help not only with diagnosis, but also changes in management,” lead author Katherine Rodriguez, MD, a pediatric critical care fellow physician at Rady Children’s Hospital, San Diego, told this news organization.

However, data on the use of rapid whole genome sequencing (rWGS) in the pediatric intensive care unit (PICU) are limited, and data from multiple institutions are lacking, Dr. Rodriguez said. In the current study, data from multiple hospitals allowed the researchers to examine differences in management across institutions, she said.

Dr. Rodriguez, with principal investigator Nicole Coufal, MD, also of Rady Children’s, and colleagues conducted the study at three children’s hospitals from March 2019 to July 2022. The study population included 80 children whose origin of illness was uncertain. The patients underwent rWGS testing in the PICU or cardiac ICU setting. The patients ranged in age from 0 to 17 years; 64% were younger than 1 year, (mean age, 2.8 years); 56% were male, and 59% were White.  

After rWGS testing, 65% of the children were positive for a genetic variant. The data prompted changes to care for 42% of these patients; 38% of the changes occurred during the patient’s PICU stay, including medication changes and procedures that were either avoided or completed.

The remaining 62% of the changes were subacute and affected management for the remainder of the child’s hospitalization and after discharge, Dr. Rodriguez explained in her presentation.

The average turnaround time for the testing was 10 days, which is important to an intensivist, who may have been hesitant to order tests because of the time involved, Dr. Rodriguez said. The current study shows that “we can get test results in a reasonable time to make meaningful changes in care,” she told this news organization.

Choosing which patients to test can be a challenge for clinicians, Dr. Rodriguez acknowledged. “We have gotten a sense of which patients are likely to have diagnostic or not diagnostic genomes, but it is also a gut feeling,” she said.

“If this child is your patient and you are concerned, if they seem sicker than expected, or have a concerning family history, then send the test,” she said. “It is becoming more affordable, and can come back quickly enough to guide treatment while the patient is still in the ICU.”

In the current study, the greatest diagnostic utility appeared in patients with cardiac symptoms, such as congenital heart disease, sudden cardiac arrest, or suspected channelopathy, Dr. Rodriguez said in her presentation.

Patients with suspected neurological disease had a 50% rate of molecular diagnosis. “Interestingly, 74% of patients with respiratory disease where an underlying genetic etiology was suspected received a molecular diagnosis,” although rWGS was not applied to general populations with RSV or other respiratory illnesses, she said.

In her presentation, Dr. Rodriguez shared examples of how genetic testing had a dramatic impact on patient survival. In one case, a 14-year-old girl presented in cardiac arrest and was found to have new-onset dilated cardiomyopathy. Whether the etiology was acquired or infectious and possibly reversible or genetic was unclear, she said.

“A diagnostic genome result within 48 hours indicated a genetic etiology,” she said. The patient was listed for heart transplant despite the incomplete infectious workup, and received a successful heart transplant 1 week after admission, Dr. Rodriguez said.

Loneliness risk elevated among young cancer survivors

Article Type
Changed

Young adults who survive cancer are more likely than cancer-free siblings to be lonely and to develop emotional distress, risky behaviors, and new chronic conditions as a result, findings from a large retrospective study suggest.

Young cancer survivors were more than twice as likely to report loneliness at study baseline and follow-up. Loneliness at these times was associated with an almost 10-fold increased risk for anxiety and a nearly 18-fold increased risk for depression.

“We observed an elevated prevalence of loneliness in survivors, compared to sibling controls, and found that loneliness was associated with emotional, behavioral, and physical health morbidities,” lead study author Chiara Papini, PhD, of St. Jude Children’s Research Hospital, Memphis, and her colleagues write. “Our results highlight the importance of identifying and screening young adult survivors of childhood cancer for loneliness and the need for targeted interventions to reduce loneliness.”

The article was published online in the journal Cancer.

Most young cancer survivors in the United States reach adulthood and need to play catch-up: make up for missed school and work, become reacquainted with old friends, and develop new friendships, social networks, and intimate relationships. Meeting these needs may be hindered by adverse physical and psychosocial problems that linger or develop after treatment, which may leave cancer survivors feeling isolated.

“Young adult survivors of childhood cancer are navigating a developmental period marked by increased social expectations, during which loneliness may have significant impact on physical and mental health,” Dr. Papini and colleagues say.

To better understand the risks for loneliness among young cancer survivors, Dr. Papini and her colleagues analyzed data from the retrospective Childhood Cancer Survivor Study, which followed young survivors who had been diagnosed with a range of cancers before age 21 years. Study participants had been treated at one of 31 study sites in North America and had survived 5 years or longer after diagnosis.

The 9,664 survivors and 2,221 randomly sampled siblings ranged in age from 19 to 39 years at the time they completed a survey that assessed emotional distress at baseline and at follow‐up a median of 6.6 years. At baseline, the median age of the survivors was 27 years, and a median of 17.5 years had passed from the time of their diagnosis.

The most common diagnoses were leukemia (35%), Hodgkin lymphoma (15%), central nervous system (CNS) tumors (14%), and bone tumors (10%). More than half (56%) had received radiation therapy.

Using multivariable models, the researchers found that survivors were more likely than siblings to report moderate to extreme loneliness at either baseline or follow‐up (prevalence ratio, 1.04) and were more than two times more likely to report loneliness at both baseline and follow‐up (PR, 2.21).

Loneliness at baseline and follow‐up was associated with a much greater risk for anxiety (relative risk, 9.75) and depression (RR, 17.86). Loneliness at follow‐up was linked with increased risks for suicidal ideation (RR, 1.52), heavy or risky alcohol consumption (RR, 1.27), and any grade 2-4 new‐onset chronic health condition (RR, 1.29), especially those that were neurologic (RR, 4.37).

Survivors of CNS tumors (odds ratio, 2.59) and leukemia (OR, 2.52) were most likely to report loneliness at both baseline and follow‐up, though survivors of four other cancer types also faced an elevated risk for loneliness: neuroblastoma (OR, 2.32), bone tumor (OR, 2.12), soft tissue sarcoma (OR, 1.78), and Hodgkin lymphoma (OR, 1.69).

Treatment type appeared to matter as well. Survivors who underwent amputation (OR, 1.82) or were treated with cranial radiation greater than or equal to 20 Gy (OR, 1.56) or corticosteroids (OR, 1.31) were more likely to report loneliness at baseline and follow‐up, compared with those who reported no loneliness at both time points.

The authors acknowledge limitations to the study, including the fact that roughly 90% of survivors and siblings were White, which limits the applicability of their results to diverse groups. In addition, the responses were self-reported without external validation.

Overall, though, the findings provide a framework for clinicians to understand and identify loneliness among young cancer survivors and help them cope with their emotions.

“The Childhood Cancer Survivor Study provides the largest and the most comprehensive dataset on childhood cancer survivors and healthy-sibling comparisons, giving us powerful data on survivorship, late effects, and psychosocial and health outcomes,” Rachel M. Moore, PhD, child psychologist at Children’s Mercy Kansas City, Mo., said in an interview.

Asking a simple question – “Are you feeling lonely?” – can identify at-risk survivors and enable health care teams to provide timely interventions that address young patients’ physical and psychological needs, said Dr. Moore, who was not involved in the study.

Dr. Moore noted that within her clinical practice, “adolescent and young adult survivors frequently discuss loneliness in their daily lives. They feel different from their peers and misunderstood. Having a conversation early in survivorship care about the experience of loneliness as a product of cancer treatment can open the door to regular screening and destigmatizing mental health services.”

Supporting young people throughout their survivorship journey is important, said Rusha Bhandari, MD, medical director of the Childhood, Adolescent, and Young Adult Cancer Survivorship Program at City of Hope, Duarte, Calif. This study can help ensure that clinicians “provide comprehensive care, including psychosocial screening and support, to meet the unique needs of our young adult survivors,” said Dr. Bhandari, who also was not involved in the research.

The National Cancer Institute and the American Lebanese Syrian Associated Charities supported the study. One co-author reported receiving corporate consulting fees. Dr. Papini, the remaining co-authors, Dr. Moore, and Dr. Bhandari report no relevant financial involvements.

Eating potatoes is healthy, study finds

Article Type
Changed

Contrary to common belief, potatoes do not have a negative effect on blood glucose levels and can actually help people lose weight, according to researchers at Louisiana State University’s Pennington Biomedical Research Center, Baton Rouge.

What to know

Potatoes are filled with key nutrients, packed with health benefits, and do not increase the risk of type 2 diabetes, as has been assumed.

People tend to eat the same weight of food regardless of calorie content to feel full, so by eating foods that are heavier in weight and that are low in calories, you can reduce the number of calories you consume.

Study participants found themselves fuller, and full more quickly, and often did not even finish their meal when the high-calorie items of their meals were replaced with potatoes.

Participants had overweight, obesity, or insulin resistance, but their blood glucose levels were not negatively affected by the potato consumption, and all of those involved actually lost weight.

People typically do not stick with a diet they don’t like or that isn't varied enough, but potatoes can be prepared in numerous ways for variety in a diet, and they are a fairly inexpensive vegetable to incorporate into a diet.

This is a summary of the article, "Low-Energy Dense Potato- and Bean-Based Diets Reduce Body Weight and Insulin Resistance: A Randomized, Feeding, Equivalence Trial," published in the Journal of Medicinal Food on November 11, 2022. The full article can be found on pubmed.ncbi.nlm.nih.gov.

A Dermatology Hospitalist Team’s Response to the Inpatient Consult Flowchart

To the Editor:

We read with interest the Cutis article by Dobkin et al1 (Cutis. 2022;109:218-220) regarding guidelines for inpatient and emergency department dermatology consultations. We agree with the authors that dermatology training is lacking in other medical specialties, which makes it challenging for teams to assess the appropriateness of a dermatology consultation in the inpatient setting. Inpatient dermatology consultation can be utilized in a hospital system to aid in rapid and accurate diagnosis, avoid inappropriate therapies, and decrease length of stay2 and readmission rates3 while providing education to the primary teams. This is precisely why in many instances the availability of inpatient dermatology consultation is so important because nondermatologists often are unable to determine whether a rash is life-threatening, benign, or something in between. From the perspective of dermatology hospitalists, there is room for improvement in the flowchart Dobkin et al1 presented to guide inpatient dermatology consultation.

To have a productive relationship with our internal medicine, surgery, pediatrics, psychiatry, and other hospital-based colleagues, we must keep an open mind when a consultation is received. We feel that the flowchart proposed by Dobkin et al1 presents too narrow a viewpoint on the utility of inpatient dermatology. It rests on assertions that other teams will be able to determine the appropriate dermatologic diagnosis without involving a dermatologist, which often is not the case.

We disagree with several recommendations in the flowchart, the first being the assertion that patients who are “hemodynamically unstable due to [a] nondermatologic problem (eg, intubated on pressors, febrile, and hypotensive)” are not appropriate for inpatient dermatology consultation.1 Although dermatologists do not commonly encounter patients with critical illness in the outpatient clinic, dermatology consultation can be extremely helpful and even lifesaving in the inpatient setting. It is unrealistic to expect the primary teams to know whether cutaneous manifestations potentially could be related to the patient’s overall clinical picture. On the contrary, we would encourage the primary team in charge of a hemodynamically unstable patient to consult dermatology at the first sign of an unexplained rash. Take for example an acutely ill patient who develops retiform purpura. There are well-established dermatology guidelines for the workup of retiform purpura,4 including prompt biopsy and assessment of broad, potentially life-threatening differential diagnoses from calciphylaxis to angioinvasive fungal infection. In this scenario, the dermatology consultant may render the correct diagnosis and recommend immediate treatment that could be lifesaving.

Secondly, we do not agree with the recommendation that a patient in hospice care is not appropriate for inpatient dermatology consultation. Patients receiving hospice or palliative care have high rates of potentially symptomatic cutaneous diseases,5 including intertrigo and dermatitis—comprising stasis, seborrheic, and contact dermatitis.6 Although aggressive intervention for asymptomatic benign or malignant skin conditions may not be in line with their goals of care, an inpatient dermatology consultation can reduce symptoms and improve quality of life. This population also is one that is unlikely to be able to attend an outpatient dermatology clinic appointment and therefore are good candidates for inpatient consultation.

Lastly, we want to highlight the difference between a stable chronic dermatologic disease and an acute flare that may occur while a patient is hospitalized, regardless of whether it is the reason for admission. For example, a patient with psoriasis affecting limited body surface area who is hospitalized for a myocardial infarction is not appropriate for a dermatology consultation. However, if that same patient develops erythroderma while they are hospitalized for cardiac monitoring, it would certainly be appropriate for dermatology to be consulted. Additionally, there are times when a chronic skin disease is the reason for hospitalization; dermatology, although technically a consulting service, would be the primary decision-maker for the patient’s care in this situation. In these scenarios, it is important for the patient to be able to establish care for long-term outpatient management of their condition; however, it is prudent to involve dermatology while the patient is acutely hospitalized to guide their treatment plan until they are able to see a dermatologist after discharge.

In conclusion, we believe that hospital dermatology is a valuable tool that can be utilized in many different scenarios. Although there are certainly situations more appropriate for outpatient dermatology referral, we would caution against overly simplified algorithms that could discourage valuable inpatient dermatology consultations. It often is worth a conversation with your dermatology consultant (when available at an institution) to determine the best course of action for each patient. Additionally, we recognize the need for more formalized guidelines on when to pursue inpatient dermatology consultation.

Authors’ Response

We appreciate the letter in response to our commentary on the appropriateness of inpatient dermatology consultations. It is the continued refining and re-evaluation of concepts such as these that allow our field to grow and improve knowledge and patient care.

We sought to provide a nonpatronizing yet simple consultation flowchart that would help guide triage of patients in need or not in need of dermatologic evaluation by the inpatient teams. Understandably, the impressions of our flowchart have been variable based on different readers’ medical backgrounds and experiences. It is certainly possible that our flowchart lacked certain exceptions and oversimplified certain concepts, and we welcome further refining of this flowchart to better guide inpatient dermatology consultations.

We do, however, disagree that the primary team would not know whether a patient is intubated in the intensive care unit for a dermatology reason. If the patient is in such a status, it would be pertinent for the primary team to conduct a timely workup that could include consultations until a diagnosis is made. We were not implying that every dermatology consultation in the intensive care unit is unwarranted, especially if it can lead to a primary dermatologic diagnosis. We do believe that a thorough history could elicit an allergy or other chronic skin condition that could save resources and spending within a hospital. Likewise, psoriasis comes in many different presentations, and although we do not believe a consultation for chronic psoriatic plaques is appropriate in the hospital, it is absolutely appropriate for a patient who is erythrodermic from any cause.

Our flowchart was intended to be the first step to providing education on when consultations are appropriate, and further refinement will be necessary.

Dermatology Articles in Preprint Servers: A Cross-sectional Study

Dermatology Articles in Preprint Servers: A Cross-sectional Study

To the Editor:

Preprint servers allow researchers to post manuscripts before publication in peer-reviewed journals. As of January 2022, 41 public preprint servers accepted medicine/science submissions.1 We sought to analyze characteristics of dermatology manuscripts in preprint servers and assess preprint publication policies in top dermatology journals.

Thirty-five biology/health sciences preprint servers1 were searched (March 3 to March 24, 2021) with keywords dermatology, skin, and cutaneous. Preprint server, preprint post date, location, metrics, journal, impact factor (IF), and journal publication date were recorded. Preprint policies of the top 20 dermatology journals—determined by impact factor of the journal (https://www.scimagojr.com/)—were reviewed. Two-tailed t tests and χ2 tests were performed (P<.05).

Characteristics of Dermatology Articles by Preprint Server

A total of 1420 articles were posted to 11 preprint servers between June 20, 2007, and February 15, 2021 (Table 1); 377 (27%) were published in peer-reviewed journals, with 350 (93%) of those published within 1 year of preprint post. Preprints were published in 203 journals with a mean IF of 6.2. Growth in preprint posts by year (2007-2020) was exponential (R2=0.78)(Figure). On average, preprints were viewed 424 times (Table 2), with published preprints viewed more often than unpublished preprints (596 vs 362 views)(P<.001). Only 23 of 786 (3%) preprints with comments enabled had feedback. Among the top 20 dermatology journals, 18 (90%) allowed preprints, 1 (5%) evaluated case by case, and 1 (5%) prohibited preprints.

Distribution of dermatology preprint articles posted by year. One dermatology preprint was posted in 2007; this data point has been excluded.
Distribution of dermatology preprint articles posted by year. One dermatology preprint was posted in 2007; this data point has been excluded.

Our study showed exponential growth in dermatology preprints, a low proportion published in peer-reviewed journals with high IFs, and a substantial number of page views for both published and unpublished preprints. Very few preprints had feedback. We found that most of the top 20 dermatology journals accept preprints. An analysis of 61 dermatology articles in medRxiv found only 51% (31/61) of articles were subsequently published.2 The low rate of publication may be due to the quality of preprints that do not meet criteria to be published following peer review.

Characteristics of Dermatology Preprint Articles

Preprint servers are fairly novel, with a majority launched within the last 5 years.1 The goal of preprints is to claim conception of an idea, solicit feedback prior to submission for peer review, and expedite research distribution.3 Because preprints are uploaded without peer review, manuscripts may lack quality and accuracy. An analysis of 57 of thelargest preprint servers found that few provided guidelines on authorship, image manipulation, or reporting of study limitations; however, most preprint servers do perform some screening.4 medRxiv requires full scientific research reports and absence of obscenity, plagiarism, and patient identifiers. In its first year, medRxiv rejected 34% of 176 submissios; reasons were not disclosed.5

The low rate of on-site comments suggests that preprint servers may not be effective for obtaining feedback to improve dermatology manuscripts prior to journal submission. Almost all of the top 20 dermatologyjournals accept preprints. Therefore, dermatologists may use these preprint servers to assert project ideas and disseminate research quickly and freely but may not receive constructive criticism.

Our study is subject to several limitations. Although our search was extensive, it is possible manuscripts were missed. Article metrics also were not available on all servers, and we could not account for accepted articles that were not yet indexed.

There has been a surge in posting of dermatology preprints in recent years. Preprints have not been peer reviewed, and data should be corroborated before incorporating new diagnostics or treatments into clinical practice. Utilization of preprint servers by dermatologists is increasing, but because the impact is still unknown, further studies on accuracy and reliability of preprints are warranted.

Preprint servers allow researchers to post manuscripts before publication in peer-reviewed journals. As of January 2022, 41 public preprint servers accepted medicine/science submissions.1 We sought to analyze characteristics of dermatology manuscripts in preprint servers and assess preprint publication policies in top dermatology journals.

Thirty-five biology/health sciences preprint servers1 were searched (March 3 to March 24, 2021) with keywords dermatology, skin, and cutaneous. Preprint server, preprint post date, location, metrics, journal, impact factor (IF), and journal publication date were recorded. Preprint policies of the top 20 dermatology journals—determined by impact factor of the journal (https://www.scimagojr.com/)—were reviewed. Two-tailed t tests and χ2 tests were performed (P<.05).

Characteristics of Dermatology Articles by Preprint Server

A total of 1420 articles were posted to 11 preprint servers between June 20, 2007, and February 15, 2021 (Table 1); 377 (27%) were published in peer-reviewed journals, with 350 (93%) of those published within 1 year of preprint post. Preprints were published in 203 journals with a mean IF of 6.2. Growth in preprint posts by year (2007-2020) was exponential (R2=0.78)(Figure). On average, preprints were viewed 424 times (Table 2), with published preprints viewed more often than unpublished preprints (596 vs 362 views)(P<.001). Only 23 of 786 (3%) preprints with comments enabled had feedback. Among the top 20 dermatology journals, 18 (90%) allowed preprints, 1 (5%) evaluated case by case, and 1 (5%) prohibited preprints.

Distribution of dermatology preprint articles posted by year. One dermatology preprint was posted in 2007; this data point has been excluded.

Our study showed exponential growth in dermatology preprints, a low proportion published in peer-reviewed journals with high IFs, and a substantial number of page views for both published and unpublished preprints. Very few preprints had feedback. We found that most of the top 20 dermatology journals accept preprints. An analysis of 61 dermatology articles in medRxiv found only 51% (31/61) of articles were subsequently published.2 The low rate of publication may be due to the quality of preprints that do not meet criteria to be published following peer review.

Characteristics of Dermatology Preprint Articles

Preprint servers are fairly novel, with a majority launched within the last 5 years.1 The goal of preprints is to claim conception of an idea, solicit feedback prior to submission for peer review, and expedite research distribution.3 Because preprints are uploaded without peer review, manuscripts may lack quality and accuracy. An analysis of 57 of thelargest preprint servers found that few provided guidelines on authorship, image manipulation, or reporting of study limitations; however, most preprint servers do perform some screening.4 medRxiv requires full scientific research reports and absence of obscenity, plagiarism, and patient identifiers. In its first year, medRxiv rejected 34% of 176 submissios; reasons were not disclosed.5

The low rate of on-site comments suggests that preprint servers may not be effective for obtaining feedback to improve dermatology manuscripts prior to journal submission. Almost all of the top 20 dermatologyjournals accept preprints. Therefore, dermatologists may use these preprint servers to assert project ideas and disseminate research quickly and freely but may not receive constructive criticism.

Our study is subject to several limitations. Although our search was extensive, it is possible manuscripts were missed. Article metrics also were not available on all servers, and we could not account for accepted articles that were not yet indexed.

There has been a surge in posting of dermatology preprints in recent years. Preprints have not been peer reviewed, and data should be corroborated before incorporating new diagnostics or treatments into clinical practice. Utilization of preprint servers by dermatologists is increasing, but because the impact is still unknown, further studies on accuracy and reliability of preprints are warranted.

The long-range thrombolysis forecast calls for tiny ultrasonic tornadoes

Article Type
Changed

 

Sticks and stones may break my bones, but clots will never hurt me

You’ve probably seen “Ghostbusters” or at least heard the theme song. Maybe you even know about the Discovery Channel’s “Mythbusters.” But now there’s a new buster in town, and it eats platitudes for breakfast: Meet Cliche-busters, LOTME’s new recurring feature.

This week, Cliche-busters takes on “Two wrongs don’t make a right.” Yum.

We start with blood clots, which are bad. Doctors go to a lot of trouble to get rid of the things because they are dangerous. A blood clot, then, is a bodily function gone wrong.

Tornadoes are also bad. Out there in the world, these violently rotating columns of air can destroy buildings, toss large objects long distances, and inspire mediocre action movies. They are examples of nature gone wrong.

Seemingly, these two wrongs – blood clots and tornadoes – are not about to make a right. Has Cliche-busters bitten off more than it can chew?

Not according to Xiaoning Jiang of North Carolina State University, Raleigh, and his team of researchers. They’ve figured out a way to use a tiny ultrasonic tornado to break down clots in the brain. “Our new work uses vortex ultrasound, where the ultrasound waves have a helical wavefront. In other words, the ultrasound is swirling as it moves forward,” he said in a statement from the university.

Xiaoning Jiang and Chengzhi Shi

Their new tool’s single transducer is small enough to fit in a catheter, and its “vortex ultrasound-induced shear force has the potential to break down clots safely and improve the efficacy of thrombolysis,” they explained in the open-access journal Research.

The investigators used cow blood in a 3D-printed model of the cerebral venous sinus for the proof-of-concept study and were able to dissolve an acute blood clot in less than 30 minutes, compared with the 15-30 hours needed with a pharmaceutical intervention, according to the written statement.

Can you hear the sound of two wrongs making a right? We can, and that closes the curtain on this cliche.
 

With age does not come wisdom

We’ve all met this person before. The sort of person who takes a 10-minute IQ test on a shifty-looking website and then proceeds to brag about a 180 IQ until the heat death of the universe. The one who worships at the altar of Mensa. Yeah, that guy. They’re never as smart as they think they are, but they’ll never, ever admit it.

It’s not exactly a secret that IQ as a measurement of intelligence is highly overrated. A lot of scientists doubt we should bother measuring it at all. That said, a higher IQ is associated with greater success in academic and financial endeavors, so it’s not absolutely worthless. And if we’re stuck with it, we may as well study it.

That brings us neatly to new research published in Brain and Behavior. Most studies into IQ and self-estimated intelligence have focused on younger adults, and the author of this study was curious if the stereotype of young men inflating their IQ, a stereotype backed up by research, persisted into older adulthood. So she conducted a survey of 159 younger adults and 152 older adults to find out.

The results in younger adults were not surprising: Younger men overestimated their actual IQ by 5-15 points, which tracks with previous research. We’re in for a bit of a surprise with the older adults, though, because the older men were more humble about their intelligence, with their estimation falling in line with their actual IQ. Older women, however, not so much. In fact, they overestimated their intelligence just as much as the younger men.

In addition, older women who perceived themselves as more attractive reported the highest self-estimated intelligence of all. That isn’t how intelligence works, but honestly, if Grandma’s out and about thinking she looks good and has the brains to go and win “Jeopardy!” do you really have the heart to tell her otherwise?
 

 

 

Fight temptation with empathy … and shoes

Relationships are tough. They all go through their respective ups and downs, but what happens when one person is feeling so down in the partnership that cheating comes to mind? Is there any way to stop it from happening?

Rawpixel

Well, a recent study suggests that there is, and it’s as simple as putting yourself in the other person’s shoes. By observing 408 heterosexual, monogamous participants in a series of experiments, psychologists in Israel and New York found that practicing empathy and “perspective taking” doesn’t necessarily stop people from cheating but it does reduces the desire.

People cheat on their significant others for many different reasons – men for a lack of sexual needs being met and women for shortfalls regarding emotional needs – but prioritizing the other person’s perspective gives the idea of being unfaithful a different view and could make one act differently, the investigators said.

Perspective taking also promotes other positive attributes to the relationship, such as the promotion of compassion and the feeling of being understood, lead author Gurit Birnbaum of Reichman University in Herzliya, Israel, said in a written statement. These things ultimately help couples navigate the rough patches and strengthen bonds, making them even less likely to cheat.

The researchers noted that even people in satisfying relationships do cheat, but this approach does encourage people to stop and think before they act. It could ultimately prevent what might be a huge mistake.

Think before they act. Hmm, that’s kind of like look before they leap, right? Sounds like a job for the Cliche-busters.

Psychiatric illnesses share common brain network

Article Type
Changed

A network of neural connections is linked to six psychiatric disorders: schizophrenia, bipolar disorder (BD), depression, addiction, obsessive-compulsive disorder (OCD), and anxiety, new research shows.

Investigators used coordinate and lesion network mapping to assess whether there was a shared brain network common to multiple psychiatric disorders. In a meta-analysis of almost 200 studies encompassing more than 15,000 individuals, they found that atrophy coordinates across these six psychiatric conditions all mapped to a common brain network.

Dr. Joseph Taylor

Moreover, lesion damage to this network in patients with penetrating head trauma correlated with the number of psychiatric illnesses that the patients were diagnosed with post trauma.

The findings have “bigger-picture potential implications,” lead author Joseph Taylor, MD, PhD, medical director of transcranial magnetic stimulation at Brigham and Women’s Hospital’s Center for Brain Circuit Therapeutics, Boston, told this news organization.

“In psychiatry, we talk about symptoms and define our disorders based on symptom checklists, which are fairly reliable but don’t have neurobiological underpinnings,” said Dr. Taylor, who is also an associate psychiatrist in Brigham’s department of psychiatry.

By contrast, “in neurology, we ask: ‘Where is the lesion?’ Studying brain networks could potentially help us diagnose and treat people with psychiatric illness more effectively, just as we treat neurological disorders,” he added.

The findings were published online in Nature Human Behavior.
 

Beyond symptom checklists

Dr. Taylor noted that, in the field of psychiatry, “we often study disorders in isolation,” such as generalized anxiety disorder and major depressive disorder.

“But what see clinically is that half of patients meet the criteria for more than one psychiatric disorder,” he said. “It can be difficult to diagnose and treat these patients, and there are worse treatment outcomes.”

There is also a “discrepancy” between how these disorders are studied (one at a time) and how patients are treated in clinic, Dr. Taylor noted. And there is increasing evidence that psychiatric disorders may share a common neurobiology.

This “highlights the possibility of potentially developing transdiagnostic treatments based on common neurobiology, not just symptom checklists,” Dr. Taylor said.

Prior work “has attempted to map abnormalities to common brain regions rather than to a common brain network,” the investigators wrote. Moreover, “prior studies have rarely tested specificity by comparing psychiatric disorders to other brain disorders.”

In the current study, the researchers used “morphometric brain lesion datasets coupled with a wiring diagram of the human brain to derive a convergent brain network for psychiatric illness.”

They analyzed four large published datasets. Dataset 1 was sourced from an activation likelihood estimation meta-analysis (ALE) of whole-brain voxel-based studies that compared patients with psychiatric disorders such as schizophrenia, BD, depression, addiction, OCD, and anxiety to healthy controls (n = 193 studies; 15,892 individuals in total).

Dataset 2 was drawn from published neuroimaging studies involving patients with Alzheimer’s disease (AD) and other neurodegenerative conditions (n = 72 studies). They reported coordinates regarding which patients with these disorders had more atrophy compared with control persons.

Dataset 3 was sourced from the Vietnam Head Injury study, which followed veterans with and those without penetrating head injuries (n = 194 veterans with injuries). Dataset 4 was sourced from published neurosurgical ablation coordinates for depression.
 

 

 

Shared neurobiology

Upon analyzing dataset 1, the researchers found decreased gray matter in the bilateral anterior insula, dorsal anterior cingulate cortex, dorsomedial prefrontal cortex, thalamus, amygdala, hippocampus, and parietal operculum – findings that are “consistent with prior work.”

However, fewer than 35% of the studies contributed to any single cluster; and no cluster was specific to psychiatric versus neurodegenerative coordinates (drawn from dataset 2).

On the other hand, coordinate network mapping yielded “more statistically robust” (P < .001) results, which were found in 85% of the studies. “Psychiatric atrophy coordinates were functionally connected to the same network of brain regions,” the researchers reported.

This network was defined by two types of connectivity, positive and negative.

“The topography of this transdiagnostic network was independent of the statistical threshold and specific to psychiatric (vs. neurodegenerative) disorders, with the strongest peak occurring in the posterior parietal cortex (Brodmann Area 7) near the intraparietal sulcus,” the investigators wrote.

When lesions from dataset 3 were overlaid onto the ALE map and the transdiagnostic network in order to evaluate whether damage to either map correlated with number of post-lesion psychiatric diagnosis, results showed no evidence of a correlation between psychiatric comorbidity and damage on the ALE map (Pearson r, 0.02; P = .766).

However, when the same approach was applied to the transdiagnostic network, a statistically significant correlation was found between psychiatric comorbidity and lesion damage (Pearson r, –0.21; P = .01). A multiple regression model showed that the transdiagnostic, but not the ALE, network “independently predicted the number of post-lesion psychiatric diagnoses” (P = .003 vs. P = .1), the investigators reported.

All four neurosurgical ablative targets for psychiatric disorders found on analysis of dataset 4 “intersected” and aligned with the transdiagnostic network.

“The study does not immediately impact clinical practice, but it would be helpful for practicing clinicians to know that psychiatric disorders commonly co-occur and might share common neurobiology and a convergent brain network,” Dr. Taylor said.

“Future work based on our findings could potentially influence clinical trials and clinical practice, especially in the area of brain stimulation,” he added.
 

‘Exciting new targets’

In a comment, Desmond Oathes, PhD, associate director, Center for Neuromodulation and Stress, University of Pennsylvania, Philadelphia, said the “next step in the science is to combine individual brain imaging, aka, ‘individualized connectomes,’ with these promising group maps to determine something meaningful at the individual patient level.”

Dr. Desmond Oathes

Dr. Oathes, who is also a faculty clinician at the Center for the Treatment and Study of Anxiety and was not involved with the study, noted that an open question is whether the brain volume abnormalities/atrophy “can be changed with treatment and in what direction.”

A “strong take-home message from this paper is that brain volume measures from single coordinates are noisy as measures of psychiatric abnormality, whereas network effects seem to be especially sensitive for capturing these effects,” Dr. Oathes said.

The “abnormal networks across these disorders do not fit easily into well-known networks from healthy participants. However, they map well onto other databases relevant to psychiatric disorders and offer exciting new potential targets for prospective treatment studies,” he added.

The investigators received no specific funding for this work. Dr. Taylor reported no relevant financial relationships. Dr. Oathes reported no relevant financial relationships.

A network of neural connections is linked to six psychiatric disorders: schizophrenia, bipolar disorder (BD), depression, addiction, obsessive-compulsive disorder (OCD), and anxiety, new research shows.

Investigators used coordinate and lesion network mapping to assess whether there was a shared brain network common to multiple psychiatric disorders. In a meta-analysis of almost 200 studies encompassing more than 15,000 individuals, they found that atrophy coordinates across these six psychiatric conditions all mapped to a common brain network.

Dr. Joseph Taylor

Moreover, lesion damage to this network in patients with penetrating head trauma correlated with the number of psychiatric illnesses that the patients were diagnosed with post trauma.

The findings have “bigger-picture potential implications,” lead author Joseph Taylor, MD, PhD, medical director of transcranial magnetic stimulation at Brigham and Women’s Hospital’s Center for Brain Circuit Therapeutics, Boston, told this news organization.

“In psychiatry, we talk about symptoms and define our disorders based on symptom checklists, which are fairly reliable but don’t have neurobiological underpinnings,” said Dr. Taylor, who is also an associate psychiatrist in Brigham’s department of psychiatry.

By contrast, “in neurology, we ask: ‘Where is the lesion?’ Studying brain networks could potentially help us diagnose and treat people with psychiatric illness more effectively, just as we treat neurological disorders,” he added.

The findings were published online in Nature Human Behavior.
 

Beyond symptom checklists

Dr. Taylor noted that, in the field of psychiatry, “we often study disorders in isolation,” such as generalized anxiety disorder and major depressive disorder.

“But what see clinically is that half of patients meet the criteria for more than one psychiatric disorder,” he said. “It can be difficult to diagnose and treat these patients, and there are worse treatment outcomes.”

There is also a “discrepancy” between how these disorders are studied (one at a time) and how patients are treated in clinic, Dr. Taylor noted. And there is increasing evidence that psychiatric disorders may share a common neurobiology.

This “highlights the possibility of potentially developing transdiagnostic treatments based on common neurobiology, not just symptom checklists,” Dr. Taylor said.

Prior work “has attempted to map abnormalities to common brain regions rather than to a common brain network,” the investigators wrote. Moreover, “prior studies have rarely tested specificity by comparing psychiatric disorders to other brain disorders.”

In the current study, the researchers used “morphometric brain lesion datasets coupled with a wiring diagram of the human brain to derive a convergent brain network for psychiatric illness.”

They analyzed four large published datasets. Dataset 1 was sourced from an activation likelihood estimation meta-analysis (ALE) of whole-brain voxel-based studies that compared patients with psychiatric disorders such as schizophrenia, BD, depression, addiction, OCD, and anxiety to healthy controls (n = 193 studies; 15,892 individuals in total).

Dataset 2 was drawn from published neuroimaging studies involving patients with Alzheimer’s disease (AD) and other neurodegenerative conditions (n = 72 studies). They reported coordinates regarding which patients with these disorders had more atrophy compared with control persons.

Dataset 3 was sourced from the Vietnam Head Injury study, which followed veterans with and those without penetrating head injuries (n = 194 veterans with injuries). Dataset 4 was sourced from published neurosurgical ablation coordinates for depression.
 

 

 

Shared neurobiology

Upon analyzing dataset 1, the researchers found decreased gray matter in the bilateral anterior insula, dorsal anterior cingulate cortex, dorsomedial prefrontal cortex, thalamus, amygdala, hippocampus, and parietal operculum – findings that are “consistent with prior work.”

However, fewer than 35% of the studies contributed to any single cluster; and no cluster was specific to psychiatric versus neurodegenerative coordinates (drawn from dataset 2).

On the other hand, coordinate network mapping yielded “more statistically robust” (P < .001) results, which were found in 85% of the studies. “Psychiatric atrophy coordinates were functionally connected to the same network of brain regions,” the researchers reported.

This network was defined by two types of connectivity, positive and negative.

“The topography of this transdiagnostic network was independent of the statistical threshold and specific to psychiatric (vs. neurodegenerative) disorders, with the strongest peak occurring in the posterior parietal cortex (Brodmann Area 7) near the intraparietal sulcus,” the investigators wrote.

When lesions from dataset 3 were overlaid onto the ALE map and the transdiagnostic network in order to evaluate whether damage to either map correlated with number of post-lesion psychiatric diagnosis, results showed no evidence of a correlation between psychiatric comorbidity and damage on the ALE map (Pearson r, 0.02; P = .766).

However, when the same approach was applied to the transdiagnostic network, a statistically significant correlation was found between psychiatric comorbidity and lesion damage (Pearson r, –0.21; P = .01). A multiple regression model showed that the transdiagnostic, but not the ALE, network “independently predicted the number of post-lesion psychiatric diagnoses” (P = .003 vs. P = .1), the investigators reported.

The future of GI

Article Type
Changed

Dear friends,

Since the last issue of The New Gastroenterologist, the GI Fellowship Match has occurred and CONGRATULATIONS to the Class of 2026! You’ve all been on an arduous journey to get here, and it’s really time to slow down and soak up as much as you can. For those who did not match, do not give up, because you are still the future of GI!

Dr. Judy A. Trieu

This issue of TNG is particularly special to me, because it marks my first official selection of articles as I embark on my own TNG journey, and the theme is the future of GI. In the “In Focus” article this quarter, Dr. Eugenia N. Uche-Anya and Dr. Tyler M. Berzin review the vast and emerging advances of artificial intelligence (AI) in colonoscopy, its role in augmenting patient care, obstacles in incorporating AI into current practice, and the future of AI in gastroenterology and hepatology. One important aspect of developing our future in these technologies includes getting involved with industry. Dr. Raman Muthusamy gives practical tips on developing and navigating relationships with industry, with highlights on understanding intellectual property and conflicts of interest.

Continuing our trek into the future of GI, telemedicine came into the fold with the COVID-19 pandemic, and it is clearly here to stay. Dr. Russ R. Arjal repositions telemedicine as a way to increase access to care and optimize practice revenue, with the aim of improving patient outcomes in the future.

Last, to ground this issue clinically, Dr. Jason Kwon and Dr. Paul T. Kroner review the gastrointestinal, hepatic, and pancreaticobiliary adverse manifestations and management of immune checkpoint inhibitors, especially now that immunotherapies have revolutionized the treatment of cancer. As gastroenterologists, we are and will be seeing more and more of these adverse events.

If you are interested in contributing or have ideas for future TNG topics, please contact me (jtrieu23@gmail.com). You may also contact Jillian Schweitzer (jschweitzer@gastro.org), managing editor of TNG.

Until next time, I leave you with a historical fun fact: Philipp Bozzini is credited with having developed the first endoscope in 1805, called the Lichtleiter (German for “light conductor”), using a candle as its light source. Adolf Kussmaul, however, developed the first rigid gastroscope in 1868, recruiting a sword-swallower in his first demonstration.
