The U.S. Preventive Services Task Force on Oct. 11 posted final recommendations on screening for anxiety, depression, and suicide risk in children and adolescents.

For the first time, the task force recommended screening for anxiety in children aged 8-18 years who do not have a diagnosed anxiety disorder and are not showing signs or symptoms of anxiety.

This “B” recommendation reflects “moderate certainty” evidence that screening for anxiety in 8- to 18-year-olds has a moderate net benefit, the task force said.

However, the task force found “insufficient” evidence to weigh the balance of benefits and harms of screening for anxiety in children aged 7 and younger and therefore issued an “I” statement.

The task force also recommended screening for children aged 12-18 years for major depressive disorder (“B” recommendation) but said there is insufficient evidence to weigh the balance of benefits and harms of screening for depression in children aged 11 and younger (“I” statement). 

These recommendations are in line with the 2016 recommendations on depression screening from the USPSTF.

“Fortunately, screening older children for anxiety and depression can identify these conditions so children and teens can receive the care that they need,” task force member Martha Kubik, PhD, RN, with George Mason University, Fairfax, Va., said in a statement.

“Unfortunately, there are key evidence gaps related to screening for anxiety and depression in younger children and screening for suicide risk in all youth,” added task force member Lori Pbert, PhD, University of Massachusetts, Worcester.

“We are calling for more research in these critical areas so we can provide health care professionals with evidence-based ways to keep their young patients healthy,” Dr. Pbert said.
 

Suicide screening

Turning to suicide, the task force says there is not enough evidence to recommend for or against screening for suicide risk in children and adolescents, and therefore issued an “I” statement – in line with the 2014 recommendation statement from the task force.

The task force acknowledged that the American Academy of Pediatrics, the American Foundation for Suicide Prevention, and experts from the National Institute of Mental Health have released a “Blueprint for Youth Suicide Prevention” that recommends universal screening for suicide risk in youth 12 years or older, while children aged 8-11 years should be screened as clinically indicated.

The task force’s final recommendation statements and corresponding evidence summaries on screening children and adolescents for anxiety, depression and suicide were published online Oct. 11, 2022, in JAMA and the USPSTF website.

The final recommendations are consistent with the 2022 draft recommendation statements on these topics.

The task force emphasized that screening is only the first step in helping children and adolescents with anxiety and depression. Youth who screen positive need further evaluation to determine if they have anxiety or depression.

After diagnosis, youth should participate in shared decision-making with their parents and healthcare professional to identify the best treatment or combination of treatments.
 

Only a first step

In an accompanying editorial, John Walkup, MD, with Ann and Robert H. Lurie Children’s Hospital, Chicago, and coauthors made the point that, for the potential of screening for pediatric anxiety disorders to be fully realized, research focused on the process of screening from evaluation to treatment needs to be a priority.

“Perhaps most critical is developing a smart and sophisticated process of screening aligned with evidence-based treatment strategies that brings added value to routine pediatric medical care and that improves physical and mental health outcomes for children and adolescents,” they wrote.

Members of the USPSTF disclosed no relevant financial relationships. Dr. Walkup reported serving as an unpaid member of the scientific council of the Anxiety and Depression Association of America, receiving royalties for anxiety-related continuing medical education activities from Wolters Kluwer and honoraria for anxiety presentations from the American Academy of Child and Adolescent Psychiatry and the American Academy of Pediatrics.

A symptom-based screening tool can identify 2-year-olds at increased risk of asthma, persistent symptoms of wheeze, and health care burden by the age of 5, according to researchers.

The validated CHILDhood Asthma Risk Tool (CHART) determines high, moderate, or low risk of asthma based on symptoms reported before the age of 3 years. It also recommends follow-up.

Potentially, CHART could be used “to identify children who need monitoring, timely symptom control, and introduction of preventive therapies,” said Padmaja Subbarao, MD, MSc, associate chief of clinical research at the Hospital for Sick Children, Toronto, and colleagues in JAMA Network Open.

“The implementation of CHART as a first-step screening tool in general practice could promote timely treatment control and, in turn, improve quality of life for patients and reduce the clinical and economic burden of asthma,” they wrote.

Dr. Subbarao and colleagues developed CHART using data from parent questionnaires and 3- and 5-year clinic visits in the CHILD study. Children were categorized as “high risk” when they experienced two or more episodes of wheeze annually at both 3 and 5 years of age, concurrent with ED visits, hospitalizations, asthma medication, or frequent dry cough. Children with only cough episodes or with cough episodes plus one episode of wheeze in the past 12 months were categorized as “low risk.”

“Our unique approach to classification of wheeze symptoms is important because it helps busy practitioners identify the smaller subset of children with more frequent or severe wheezing episodes who have a higher probability of continued symptoms and impaired lung function in adult life among most children with infrequent wheeze,” Dr. Sabbarao and coauthors said.

Their diagnostic study to evaluate CHART’s predictive capacity showed that the tool had the highest proportion of true-positive asthma at 5 years (sensitivity, 50.0%), compared with physicians’ diagnosis at 3 years (sensitivity, 43.5%), and positive standardized modified Asthma Predictive Index (mAPI) at 3 years (sensitivity, 24.4%).

CHART also outperformed physician assessments and mAPI for predicting persistent wheeze at 5 years and provided the highest predictive capacity for subsequent health care use at 5 years of age. The study showed that it identified 20% more children with emergency department visits or hospitalizations than the standardized mAPI (sensitivity 45.5% vs. 25.0%), and approximately 10% more at-risk children than physician diagnosis.

“These findings are especially important given that many hospitalizations are avoidable if appropriate treatment and management of asthma are implemented at primary care,” Dr. Subbarao and colleagues wrote.

CHART has been validated in two external cohorts: a general-population cohort of 2,185 children from the Raine Study in Australia at 5 years of age; and the other a high-risk cohort of 349 children from the Canadian Asthma Primary Prevention Study at 7 years of age.

“We want to highlight the importance of periodic monitoring of wheeze symptoms and simplify the identification of high-risk children for primary care providers and parents or caregivers,” said Dr. Subbarao, who is director of the CHILD study and professor of pediatrics at the University of Toronto.

The tool “does not identify the underlying biology, which could impact the efficacy of our current standard asthma treatment,” Dr. Subbarao emphasized. CHART has not been tested in low-prevalence settings or in countries in which the term “wheeze” is not commonly recognized, she added.

“CHART helps you focus your crystal ball a little bit, look into the future, and see what’s going to happen,” said Harold Farber, MD, a pediatric pulmonologist who was not involved in the study. “It’s useful even if it just confirms what I’m already doing clinically.”

Dr. Farber, who is professor of pediatrics at Baylor College of Medicine and the Texas Children’s Hospital, Houston, cautioned that the predictive value of CHART is based on the diagnosis of asthma, and that this can differ across health care communities. “Between the extremes and what’s considered borderline, there’s a lot of diagnostic variation in what we call asthma,” he explained in an interview. “The diagnosis is, to some extent, subjective.”

However, Dr. Farber agreed that two or more wheezing episodes in the past 12 months – enough to require treatment – puts a child at very high risk for future wheezing. “Kids with a bunch of wheezing problems at 3 years are likely to have wheezing problems at 5. We have to think about what we can do for a toddler today to keep him from wheezing later.”

CHART is simple to use, the investigators said. The information needed can be easily gathered through interviews and parent-reported questionnaires, then put into the electronic medical record to flag children at high risk for further investigation, and well as those at low or moderate risk for monitoring.

Parents and caregivers can also use CHART to document symptoms every 6 months in children older than 1 year of age, said Dr. Subbarao. This information can be brought to the attention of the doctor “to facilitate a deeper discussion,” she suggested.

This study was funded by the Canadian Institutes of Health Research, Allergy, Genes and Environment Network of Centers of Excellence; Don and Debbie Morrison; Women’s and Children Health Research Institute; and Canada Research Chairs. Dr Subbarao reported having no potential conflicts of interest. Coauthor Vanessa Breton, PhD, disclosed being employed by F. Hoffmann-La Roche Ltd., and coauthor Elinor Simons, MD, PhD, reported membership on the Sanofi-Genzyme Data Monitoring Board. No other conflicts of interest were reported by the study authors.

A real-world analysis in the United Kingdom found that a fully covered metal stent is safe and effective at controlling anastomotic strictures (AS) following liver transplants.

Biliary AS occurs in an estimated 5%-32% of patients following a liver transplant. Generally, these have been managed by insertion of side-by-side plastic stents to remodel the stricture, but this often required multiple procedures to resolve the problem. More recently, transpapillary fully covered self-expanding metallic stents (FCSEMSs) have been introduced and they appear to perform equivalently to their plastic counterparts while requiring fewer procedures.

The new study “is yet another large experience demonstrating that use of fully covered metal stents for treating anastomotic biliary strictures is highly effective and also cost-effective because you really decrease the number of ERCPs [endoscopic retrograde cholangiopancreatographies] that are required to treat an anastomotic stricture,” said Vladimir Kushnir, MD, who was asked to comment on the study, which was published in Therapeutic Advances in Gastroenterology.

The researchers analyzed retrospective data from 162 consecutive patients who underwent ERCP with intraductal self-expanding metal stent (IDSEMS) insertion at nine tertiary centers. The procedures employed the Kaffes (Taewoong Niti-S) biliary covered stent, which is not available in the United States. Unlike conventional FCSEMSs, the device does not have to traverse the papilla. It is also shorter and includes an antimigration waist and removal wires that may reduce the risk of silent migration. Small case series suggested efficacy in the treatment of post–liver transplant AS.

There were 176 episodes of stent insertion among the 162 included patients; 62% of patients were male, and the median age at transplant was 54 years. Etiologies included hepatocellular carcinoma (22%), alcohol-related liver disease (18%), and nonalcoholic fatty liver disease (12%). The median time to development of a stricture was 24.9 weeks. Among all patients, 35% had previously received stents; 75% of those were plastic stents.

Overall, 10% of patients experienced stricture recurrence at a median interval of 19 weeks following stent removal. Median stent emplacement was 15 weeks, and 81% of patients had a resolution of their strictures.

Dr. Kushnir, from Washington University in St. Louis, highlighted the differences between the stent used in the study and those currently available in the United States. “This type of stent is a self-expanding metal stent that’s covered, but what’s different about it is that it’s designed to go completely within the bile duct, whereas a traditional fully covered metal stent traverses the major duodenal papilla.”

Despite those differences, he believes that the study can inform current practice in the United States. “In situations where you’re faced with a question of whether or not you leave multiple plastic stents in, or you put a full metal stent in that’s going to be fully within the bile duct, I think this data does provide some reassurance. If you’re using one of the traditional stents that we have in the United States and putting it fully within the bile duct, you do need to be prepared to have a little bit of a harder time removing the stent when the time comes for the removal procedure, which could require cholangioscopy. But this does provide some evidence to back up the practice of using fully covered metal stents fully within the bile duct to remediate anastomotic strictures that may be just a little too high up to treat traditionally with a stent that remains transpapillary,” said Dr. Kushnir.

The study also suggests an avenue for further research. “What’s also interesting about this study is that they only left the stents in for 3 months. In most clinical trials, where we’ve used fully covered metal stents for treating anastomotic biliary strictures, you leave the stent in from anywhere from 6 to 12 months. So with only 3 months dwell time they were able to get pretty impressive results, at least in the short term, in a retrospective study, so it does raise the question of should we be evaluating shorter dwell times for stents in treating anastomotic strictures when we’re using a fully covered metal stent that’s a larger diameter?” said Dr. Kushnir.

The authors noted some limitations, such as the retrospective design, small sample size, and lack of control group. They also noted that the multicenter design may have introduced heterogeneity in patient management and follow-up.

“In conclusion, IDSEMS appear to be safe and highly efficacious in the management of [post–liver transplant] AS,” concluded the authors. “Long-term outcomes appear good with low rates of AS recurrence.”

The authors declare no conflicts of interest. Dr. Kushnir is a consultant for ConMed and Boston Scientific.

If you’re using one of the traditional stents that we have in the United States and putting it fully within the bile duct, you do need to be prepared to have a little bit of a harder time removing the stent when the time comes for the removal procedure, which could require cholangioscopy. But this does provide some evidence to back up the practice of using fully covered metal stents fully within the bile duct to remediate anastomotic strictures that may be just a little too high up to treat traditionally with a stent that remains transpapillary,” said Dr. Kushnir.

The study also suggests an avenue for further research. “What’s also interesting about this study is that they only left the stents in for 3 months. In most clinical trials, where we’ve used fully covered metal stents for treating anastomotic biliary strictures, you leave the stent in from anywhere from 6 to 12 months. So with only 3 months dwell time they were able to get pretty impressive results, at least in the short term, in a retrospective study, so it does raise the question of should we be evaluating shorter dwell times for stents in treating anastomotic strictures when we’re using a fully covered metal stent that’s a larger diameter?” said Dr. Kushnir.

The authors noted some limitations, such as the retrospective design, small sample size, and lack of control group. They also noted that the multicenter design may have introduced heterogeneity in patient management and follow-up.

“In conclusion, IDSEMS appear to be safe and highly efficacious in the management of [post–liver transplant] AS,” concluded the authors. “Long-term outcomes appear good with low rates of AS recurrence.”

The authors declare no conflicts of interest. Dr. Kushnir is a consultant for ConMed and Boston Scientific.

A real-world analysis in the United Kingdom found that a fully covered metal stent is safe and effective at controlling anastomotic strictures (AS) following liver transplants.

Biliary AS occurs in an estimated 5%-32% of patients following a liver transplant. Generally, these have been managed by insertion of side-by-side plastic stents to remodel the stricture, but this often required multiple procedures to resolve the problem. More recently, transpapillary fully covered self-expanding metallic stents (FCSEMSs) have been introduced and they appear to perform equivalently to their plastic counterparts while requiring fewer procedures.

The new study “is yet another large experience demonstrating that use of fully covered metal stents for treating anastomotic biliary strictures is highly effective and also cost-effective because you really decrease the number of ERCPs [endoscopic retrograde cholangiopancreatographies] that are required to treat an anastomotic stricture,” said Vladimir Kushnir, MD, who was asked to comment on the study, which was published in Therapeutic Advances in Gastroenterology.

The researchers analyzed retrospective data from 162 consecutive patients who underwent ERCP with intraductal self-expanding metal stent (IDSEMS) insertion at nine tertiary centers. The procedures employed the Kaffes (Taewoong Niti-S) biliary covered stent, which is not available in the United States. Unlike conventional FCSEMSs, the device does not have to traverse the papilla. It is also shorter and includes an antimigration waist and removal wires that may reduce the risk of silent migration. Small case series suggested efficacy in the treatment of post–liver transplant AS.

There were 176 episodes of stent insertion among the 162 included patients; 62% of patients were male, and the median age at transplant was 54 years. Etiologies included hepatocellular carcinoma (22%), alcohol-related liver disease (18%), and nonalcoholic fatty liver disease (12%). The median time to development of a stricture was 24.9 weeks. Among all patients, 35% had previously received stents; 75% of those were plastic stents.

Overall, 10% of patients experienced stricture recurrence at a median interval of 19 weeks following stent removal. Median stent emplacement was 15 weeks, and 81% of patients had a resolution of their strictures.

Dr. Kushnir, from Washington University in St. Louis, highlighted the differences between the stent used in the study and those currently available in the United States. “This type of stent is a self-expanding metal stent that’s covered, but what’s different about it is that it’s designed to go completely within the bile duct, whereas a traditional fully covered metal stent traverses the major duodenal papilla.”

A new consensus statement summarizes the benefits, limitations, and challenges of using automated insulin delivery (AID) systems and provides recommendations for use by people with diabetes.  

“Automated insulin delivery systems” is becoming the standard terminology – including by the U.S. Food and Drug Administration – to refer to systems that integrate data from a continuous glucose monitoring (CGM) system via a control algorithm into an insulin pump in order to automate subcutaneous insulin delivery. “Hybrid AID” or “hybrid closed-loop” refers to the current status of these systems, which still require some degree of user input to control glucose levels.

The term “artificial pancreas” was used interchangeably with AID in the past, but it doesn’t take into account exocrine pancreatic function. The term “bionic pancreas” refers to a specific system in development that would ultimately include glucagon along with insulin.

The new consensus report, titled “Automated insulin delivery: Benefits, challenges, and recommendations,” was published online in Diabetes Care and Diabetologia.  

The document is geared toward not only diabetologists and other specialists, but also diabetes nurses and specialist dietitians. Colleagues working at regulatory agencies, health care organizations, and related media might also benefit from reading it.

It is endorsed by two professional societies – the European Association for the Study of Diabetes and the American Diabetes Association – and contrasts with other statements about AID systems that are sponsored by their manufacturers, noted document co-author Mark Evans, PhD, professor of diabetic medicine, University of Cambridge, England, in a statement.

“Many clinically relevant aspects, including safety, are addressed in this report. The aim ... is to encourage ongoing improvement of this technology, its safe and effective use, and its accessibility to all who can benefit from it,” Dr. Evans said.

Lead author Jennifer Sherr, MD, PhD, pediatric endocrinology, Yale University, New Haven, Conn., commented that the report “addresses the clinical usage of AID systems from a practical point of view rather than as ... a meta-analysis or a review of all relevant clinical studies. ... As such, the benefits and limitations of systems are discussed while also considering safety, regulatory pathways, and access to this technology.”
 

AID systems do not mean diabetes is “cured”

Separate recommendations provided at the end of the document are aimed at specific stakeholders, including health care providers, patients and their caregivers, manufacturers, regulatory agencies, and the research community.  

The authors make clear in the introduction that, while representing “a significant movement toward optimizing glucose management for individuals with diabetes,” the use of AID systems doesn’t mean that diabetes is “cured.” Rather, “expectations need to be set adequately so that individuals with diabetes and providers understand what such systems can and cannot do.”

In particular, current commercially available AID systems require user input for mealtime insulin dosing and sometimes for correction doses of high blood glucose levels, although the systems at least partially automate that.

“When integrated into care, AID systems hold promise to relieve some of the daily burdens of diabetes care,” the authors write.

The statement also details problems that may arise with the physical devices, including skin irritation from adhesives, occlusion of insulin infusion sets, early CGM sensor failure, and inadequate dosing algorithms.

“Individuals with diabetes who are considering this type of advanced diabetes therapy should not only have appropriate technical understanding of the system but also be able to revert to standard diabetes treatment (that is, nonautomated subcutaneous insulin delivery by pump or injections) in case the AID system fails. They should be able to independently troubleshoot and have access to their health care provider if needed.”

To monitor the impact of the technology, the authors emphasize the importance of the time-in-range metric derived from CGM, with the goal of achieving 70% or greater time in target blood glucose range.

Separate sections of the document address the benefits and limitations of AID systems, education and expectations for both patients and providers, and patient and provider perspectives, including how to handle urgent questions.

Other sections cover special populations such as pregnant women and people with type 2 diabetes, considerations for patient selection for current AID systems, safety, improving access to the technology, liability, and do-it-yourself systems.
 

Recommendations for health care professionals

A table near the end of the document provides specific recommendations for health care professionals, including the following:

• Be knowledgeable about AID systems and nuances of different systems, including their distinguishing features as well as strengths and weaknesses.
• Inform patients with diabetes about AID systems, including review of currently available systems, and create realistic expectations for device use.
• Involve patients with diabetes in shared decision-making when considering use of AID systems.
• Share information with patients with diabetes, as well as their peers, about general standards set by national and international guidelines on AID systems.
• Provide an on-call number or method by which a person with diabetes can always access support from a health care provider at the practice, including weekends and nights.
• Implement, potentially, protocols on times when AID systems should not be used.
• Use an individual’s health data to improve quality of care and health outcomes.

The diversity of neuroendocrine tumors (NETs) – which includes variation in location, mutational profile, and response to therapy – may be due to divergent cellular origins in different tissue sites, according to a new study.

The pathogenesis of gastroenteropancreatic neoplasms (GEP-NENs) is poorly understood, in part because of a lack of modeling systems, according to Suzann Duan, PhD, and colleagues. They are a heterogeneous group of tumors that are increasingly prevalent in the United States. GEP-NENs arise from endocrine-producing cells and include gastric carcinoids, gastrinomas, and pancreatic NETs.

Despite the general mystery surrounding GEP-NENs, there is at least one clue in the form of the MEN1 gene. Both inherited and sporadic mutations of this gene are associated with GEP-NENs. Menin is a tumor suppressor protein, and previous studies have shown that inactivation of MEN1 leads to loss of that protein and is associated with endocrine tumors in the pancreas, pituitary, and upper GI tract.

In new research published in Cellular and Molecular Gastroenterology and Hepatology, researchers investigated the role of MEN1 in neuroendocrine cell development and traced it to a potential role in the development of NETs.

Patients with MEN1 mutations are at increased risk of gastrinomas, which lead to increased production of the peptide hormone gastrin. Gastrin increases acid production and can lead to hyperplasia in parietal and enterochromaffin cells. These generally develop in Brunner’s glands within the submucosa of the duodenum. At time of diagnosis, more than half of such tumors have developed lymph node metastases.

It remains unclear how loss of MEN1 suppresses gastrin production. Previous research showed that homozygous MEN1 deletion in mice is lethal to embryos, while leaving one copy intact leads to heightened risk of endocrine tumors in the pancreas and pituitary gland, but not in the GI tract. The studies did not reveal the tumor’s origin cell.

The researchers developed a novel mouse model in which MEN1 is conditionally deleted from the GI tract epithelium. This led to hyperplasia of gastrin-producing cells (G cells) in the antrum, as well as hypergastrinemia and development of gastric NETs. Exposure to a proton pump inhibitor accelerated gastric NET development, and the researchers identified expansion of enteric glial cells that expressed gastrin and GFAP. Glial cells that differentiated into endocrine phenotype were associated with a reversible loss of menin. “Taken together, these observations suggest that hyperplastic G cells might emerge from reprogrammed neural crest–derived cells in addition to endoderm-derived enteroendocrine cells,” the authors wrote.

That idea is supported by previous research indicating that multipotent glial cells expressing GFAP or SOX10 may play a developmental role in formation of neuroendocrine cells.

With this in mind, the researchers deleted MEN1 in GFAP-expressing cells to see if it would promote neuroendocrine cell development.

The result was hyperplasia in the gastric antrum and NETs in the pituitary and pancreas. To the researchers’ surprise, NET development was associated with loss of GFAP expression as well as activation of neuronal and neuroendocrine-related genes in the stomach, pancreas, and pituitary. There was universal reduction of GFAP protein expression in pituitary and pancreatic NETs, but GFAP transcript levels stayed steady in the gastric antra despite a reduction in GFAP-reporter expression. This could indicate that the menin protein interacts with GFAP. If so, eliminating menin in GFAP-positive cells could change the localization of GFAP, which may in turn lead to changes in glial cell identity.

When the researchers compared transcriptomes of hyperplastic antral tissues to well-differentiated NETs, they found that NETs exhibited a greater loss of glial-restricted progenitor lineage–associated genes as well as more downregulation of gliogenesis-directing factors. “Thus, the transition from a glial-to-neuronal cell phenotype appears to promote the progression from neuroendocrine cell hyperplasia to tumor development,” the authors wrote. They also found that NETs have higher levels of expression of genes associated with neural stem and progenitor cells, as well as upregulation of factors secreted from neural crest cells that promote neurogenesis and restrict the glial cell fate. Many of these factors are part of the Hedgehog signaling pathway, and menin is known to repress Hedgehog signaling.

Intestinal glial cells have a high degree of plasticity. They can become neuronal progenitor cells and yet they can dedifferentiate to differentiate again into other cell lineages.

The research could eventually lead to identification of unique cells-of-origin for these tumors. The authors say that the diversity of the tumors – which includes variation in location, mutational profile, and response to therapy – may be due to divergent cellular origins in different tissue sites. “Defining the cells-of-origin and the events preceding neoplastic transformation will be critical to informing molecular signaling pathways that can then be targeted therapeutically,” the authors wrote.

The authors disclosed no conflicts of interest.

Previous research showed that homozygous MEN1 deletion in mice is lethal to embryos, while leaving one copy intact leads to heightened risk of endocrine tumors in the pancreas and pituitary gland, but not in the GI tract. The studies did not reveal the tumor’s origin cell.

The researchers developed a novel mouse model in which MEN1 is conditionally deleted from the GI tract epithelium. This led to hyperplasia of gastrin-producing cells (G cells) in the antrum, as well as hypergastrinemia and development of gastric NETs. Exposure to a proton pump inhibitor accelerated gastric NET development, and the researchers identified expansion of enteric glial cells that expressed gastrin and GFAP. Glial cells that differentiated into endocrine phenotype were associated with a reversible loss of menin. “Taken together, these observations suggest that hyperplastic G cells might emerge from reprogrammed neural crest–derived cells in addition to endoderm-derived enteroendocrine cells,” the authors wrote.

That idea is supported by previous research indicating that multipotent glial cells expressing GFAP or SOX10 may play a developmental role in formation of neuroendocrine cells.

With this in mind, the researchers deleted MEN1 in GFAP-expressing cells to see if it would promote neuroendocrine cell development.

The result was hyperplasia in the gastric antrum and NETs in the pituitary and pancreas. To the researchers’ surprise, NET development was associated with loss of GFAP expression as well as activation of neuronal and neuroendocrine-related genes in the stomach, pancreas, and pituitary. There was universal reduction of GFAP protein expression in pituitary and pancreatic NETs, but GFAP transcript levels stayed steady in the gastric antra despite a reduction in GFAP-reporter expression. This could indicate that the menin protein interacts with GFAP. If so, eliminating menin in GFAP-positive cells could change the localization of GFAP, which may in turn lead to changes in glial cell identity.

When the researchers compared transcriptomes of hyperplastic antral tissues to well-differentiated NETs, they found that NETs exhibited a greater loss of glial-restricted progenitor lineage–associated genes as well as more downregulation of gliogenesis-directing factors. “Thus, the transition from a glial-to-neuronal cell phenotype appears to promote the progression from neuroendocrine cell hyperplasia to tumor development,” the authors wrote. They also found that NETs have higher levels of expression of genes associated with neural stem and progenitor cells, as well as upregulation of factors secreted from neural crest cells that promote neurogenesis and restrict the glial cell fate. Many of these factors are part of the Hedgehog signaling pathway, and menin is known to repress Hedgehog signaling.

Intestinal glial cells have a high degree of plasticity. They can become neuronal progenitor cells and yet they can dedifferentiate to differentiate again into other cell lineages.

The research could eventually lead to identification of unique cells-of-origin for these tumors. The authors say that the diversity of the tumors – which includes variation in location, mutational profile, and response to therapy – may be due to divergent cellular origins in different tissue sites. “Defining the cells-of-origin and the events preceding neoplastic transformation will be critical to informing molecular signaling pathways that can then be targeted therapeutically,” the authors wrote.

The authors disclosed no conflicts of interest.

ANAHEIM, CALIF. – Opioids are the most common cause of fatal poisonings in young children, and their contribution to children’s deaths has been increasing, according to research presented at the American Academy of Pediatrics National Conference.

The study found that the proportion of deaths in U.S. children linked to opioids has doubled since the mid-2000s, tracking the course of the epidemic in adults in this country.

“What is striking about our study is how the opioid epidemic has not spared our nation’s infants or young children,” Christopher Gaw, MD, MA, a pediatric emergency medicine fellow physician at Children’s Hospital of Philadelphia, said in an interview. “There is important work being done to reduce unnecessary opioid prescribing, drug diversion, and treatment of substance use disorders. These efforts – though not directly related to children – also help protect them, since they can reduce the chance of exposure to opioids in the home.”

Dr. Gaw and his colleagues analyzed data in Child Death Reviews from 40 states that participate in the National Fatality Review Case Reporting System, focusing on children aged 5 years and younger who died from a poisoning between 2005 and 2018. During that time, 731 child poisoning deaths were reported to the system – of which nearly half (47%) involved opioids as the poisoning agent – up from 24% in 2005. More than 4 in 10 deaths (42%) involved children under age 1.

Most of the deaths (61%) occurred in the child’s home, and in even more cases (71%) the child was being supervised when the poisoning occurred, most often by a parent (58.5%). The others supervising children were usually a grandparent (11%) or another relative (5.5%). The child was in view of the supervising individual in 28.5% of the deaths. A child protective services case was opened in 13% of the cases.

“Supervising a child is hard. Kids are constantly exploring and moving,” Dr. Gaw said. “A child may find a dropped medication on the floor that a caregiver doesn’t see, or a child may get into a bag or a purse when a caregiver is looking the other way. Poisonings can happen in a split second.”

Expecting caregivers to be able to watch kids every moment and always be within arm’s reach to prevent an accident is unrealistic, Dr. Gaw said, so families should focus on preparedness.

“Young children can’t tell the difference between a deadly substance versus a substance that is harmless or would only cause some harm. The best way to protect children is to prevent the poisoning from happening in the first place,” Dr. Gaw said. ”

It is recommended that caregivers keep the Poison Control Center’s national 24/7 hotline in their phones: (800) 222-1222.

Two-thirds of the cases Dr. Gaw examined did not involve a call to a poison control center, but most did involve a call to 911.

“My guess is that caregivers likely called 911 instead of poison control because the child was likely critically ill or deceased when found,” Dr. Gaw said, noting that his group did not have access to descriptive information about 911 calls. “If a child is critically ill and a caregiver called poison control first, they would be referred to 911.”

If a child looks healthy but has just swallowed something dangerous or deadly, Dr. Gaw said poison control can guide the family to getting prompt medical attention that could be lifesaving.

“We don’t expect the public to know what substances are harmless, harmful, or deadly,” he said. “People should always call poison control if there is any concern, even if the child looks well.”

Some poison control centers are working to increase the ways people can reach them, including through texting, apps, or online chat, he added.

Gary A. Smith, MD, DrPH, president of the nonprofit Child Injury Prevention Alliance in Columbus, Ohio, and director of the Center for Injury Research and Policy at Nationwide Children’s Hospital, said the high level of supervision in these cases was not surprising.

”We have shown that most children are being directly supervised at the moment of injury for baby walker–related injuries, firework-related injuries, and other types of injuries that we have studied,” Dr. Smith said in an interview. “Injuries happen quickly and generally do not give a parent or caregiver time to react.”

“This dispels the myth that parental supervision is the key to injury prevention,” Dr. Smith said. “Although supervision helps, it is not adequate. These injuries occur to children of good and caring parents. The message for pediatricians is that we must create safe environments for children and design hazards out of existence to effectively prevent poisoning and other injuries.”

That preventive approach has been used for infectious disease and other public health problems, he added.

“Prescription opioids must be kept in their original containers with children-resistant closures and be stored up, away, and out of sight of children, preferably in a locked location,” Dr. Smith said. “If adults use illicit opioids or any other illicit substances – which are commonly laced with fentanyl – they should not use or store them in the home where children can access them.”

Over-the-counter pain, cold, and allergy medications were the second most common cause of death, occurring in 15% of cases.

“There has been a lot of work over the years among health care providers to counsel families on the proper dosing and use of medications such as Tylenol, Motrin, and Benadryl,” Dr. Gaw said. “There has also been a push to educate families that using antihistamines, such as Benadryl, to sedate their children can be dangerous and, depending on the dose, potentially deadly.”

Another 14% of cases were an unspecified illicit drug, and 10% were an unspecified over-the-counter or prescription medication. Carbon monoxide poisoning made up 6% of cases, and the remaining substances included amphetamines, antidepressants, cocaine, and alcohol.

Over half the deaths in 1-year-olds (61%) and children aged 2-5 (54%) were due to opioid poisoning, as were a third of deaths in infants (34%). Most of the poisonings involving amphetamines (81%), cocaine (84%), and alcohol (61.5%) occurred in infants under age 1.

Dr. Smith said that harm-reduction strategies, such as having naloxone on hand and using fentanyl test strips, can reduce the likelihood of death from illicit drugs.
 

Reducing stigma can save lives

“Referring parents to services for individuals who use drugs is key,” Dr. Smith said. “Treating this as a public health problem without stigmatizing the behavior is something that pediatricians and other health care professionals must remember.” As a resource for other pediatricians, Dr. Gaw noted that CHOP’s poison control center medical director Kevin Osterhoudt, MD produced a 25-minute podcast that covers common causes of poisonings, use of naloxone in children, and prevention tips.

“Naloxone is an effective antidote to opioid poisonings,” Dr. Gaw said. “We often think of using it in adults, but this is also a lifesaving medication for children poisoned by opioids. Educating people on recognizing the signs and symptoms of opioid poisoning and helping them feel empowered to use naloxone is something the public health world is working on.”

Dr. Gaw and Dr. Smith had no relevant disclosures. No external funding was noted for the study.

Big-name hospital chains across the United States are opening dedicated centers to help patients dealing with long COVID. But so are the lower-profile clinics and hospitals run by cities, counties and states – including Harborview Medical Center in Seattle.

The Harborview clinic, operated by King County, is an example of how public health agencies are stepping up to treat people experiencing long COVID.

They serve areas ranging from Campbell County, Wyo., with 47,000 residents, to New York City, with its 8.4 million people. Many providers working there are searching for innovative ways to approach this lingering illness with its variety of symptoms, from brain fog to shortness of breath to depression and more.

Their efforts often fall below the radar, with still-scant serious media attention to long COVID or the public health employees working to treat ailing patients.

Why are state and local health agencies taking on these duties?

They’re leading the way in part because the federal government has made only limited efforts, said Lisa McCorkell, a cofounder of the Patient-Led Research Collaborative. The international group was founded in spring 2020 by researchers who are also long COVID patients.

“It’s a big reason why long COVID isn’t talked about as much,” Ms. McCorkell said. “It’s definitely a national issue. But it trickles down to state and local health departments, and there’s not enough resources.”

The government clinics may be accessible to people without insurance and often are cheaper than clinics at private hospitals.

Harborview has treated more than 1,000 patients with long COVID, and another 200 patients are awaiting treatment, said Jessica Bender, MD, a codirector of the University of Washington Post-COVID Rehabilitation and Recovery Clinic in Seattle’s First Hill neighborhood.

The group Survivor Corps offers lists by states of clinics. While the publicly run clinics may be less expensive or even free for some patients, methods of payment vary from clinic to clinic. Federally qualified health clinics offer treatment on a sliding scale. For instance, the Riverside University Health System in California has federally qualified centers. And other providers who are not federally qualified also offer care paid for on a sliding scale. They include Campbell County Health, where some residents are eligible for discounts of 25%-100%, said spokesperson Norberto Orellana.

At Harborview, Dr. Bender said the public hospital’s post-COVID clinic initially began with a staff of rehabilitation doctors but expanded in 2021 to include family and internal medicine doctors. And it offers mental health programs with rehabilitation psychologists who instruct on how to deal with doctors or loved ones who don’t believe that long COVID exists.

“I have patients who really have been devastated by the lack of support from coworkers [and] family,” Dr. Bender said.

In Campbell County, Wyo., the pandemic surge did not arrive in earnest until late 2021. Physical therapists at Campbell County’s Health Rehabilitation Services organized a rehabilitation program for residents with long COVID after recognizing the need, said Shannon Sorensen, rehabilitation director at Campbell County Health.

“We had patients coming in showing chest pain, or heart palpitations. There were people trying to get back to work. They were frustrated,” Ms. Sorensen said.

Myalgic encephalomyelitis and chronic fatigue syndrome activists have embraced the fight to recognize and help long COVID patients, noting the similarities between the conditions, and hope to help kickstart more organized research, treatment and benefits for long COVID sufferers and myalgic encephalomyelitis/chronic fatigue syndrome patients alike.

In Ft. Collins, Colo., disability activist Alison Sbrana has long had myalgic encephalomyelitis. She and other members of the local chapter of ME Action have met with state officials for several years and are finally seeing the results of those efforts.

Colorado Gov. Jared Polis has created the full-time position of policy adviser for long COVID and post–viral infection planning.

“This is one way forward of how state governments are (finally) paying attention to infection-triggered chronic illnesses and starting to think ahead on them,” Ms. Sbrana said.

New York City’s Health + Hospitals launched what may be the most expansive long COVID treatment program in the nation in April 2021. Called AfterCare, it provides physical and mental health services as well as community support systems and financial assistance.

A persistent issue for patients is that there isn’t yet a test for long COVID, like there is for COVID-19, said Amanda Johnson, MD, assistant vice president for ambulatory care and population health at New York Health + Hospitals. “It’s in many ways a diagnosis of exclusion. You have to make sure their shortness of breath isn’t caused by something else. The same with anemia,” she said.

California’s Department of Public Health has a detailed website devoted to the topic, including videos of “long haulers” describing their experiences.

Vermont is one of several states studying long COVID, said Mark Levine, MD, the state health commissioner. The state, in collaboration with the University of Vermont, has established a surveillance project to determine how many people have long COVID, as well as how severe it is, how long it lasts, and potential predispositions.

The University of Utah, Salt Lake City, established a comprehensive COVID-19 clinic more than a year ago that also handles long COVID patients, said Jeannette Brown, MD, PhD, an associate professor at the school and director of the COVID-19 clinic.

Jennifer Chevinsky, MD, MPH, already had a deep understanding of long COVID when she landed in Riverside County, Calif., in the summer of 2021. She came from Atlanta, where as part of her job as an epidemic intelligence service officer at the CDC, she heard stories of COVID-19 patients who were not getting better.

Now she is a deputy public health officer for Riverside County, in a region known for its deserts, sizzling summer temperatures and diverse populations. She said her department has helped launch programs such as post–COVID-19 follow-up phone calls and long COVID training programs that reach out to the many Latino residents in this county of 2.4 million people. It also includes Black and Native American residents.

“We’re making sure information is circulated with community and faith-based organizations, and community health workers,” she said.

Ms. McCorkell said there is still much work to do to raise public awareness of the risks of long COVID and how to obtain care for patients. She would like to see a national public health campaign about long COVID, possibly spearheaded by the Centers for Disease Control and Prevention in partnership with local health workers and community-based organizations.

“That,” she said, “could make a big difference.”

A persistent issue for patients is that there isn’t yet a test for long COVID, like there is for COVID-19, said Amanda Johnson, MD, assistant vice president for ambulatory care and population health at New York Health + Hospitals. “It’s in many ways a diagnosis of exclusion. You have to make sure their shortness of breath isn’t caused by something else. The same with anemia,” she said.

California’s Department of Public Health has a detailed website devoted to the topic, including videos of “long haulers” describing their experiences.

Vermont is one of several states studying long COVID, said Mark Levine, MD, the state health commissioner. The state, in collaboration with the University of Vermont, has established a surveillance project to determine how many people have long COVID, as well as how severe it is, how long it lasts, and potential predispositions.

The University of Utah, Salt Lake City, established a comprehensive COVID-19 clinic more than a year ago that also handles long COVID patients, said Jeannette Brown, MD, PhD, an associate professor at the school and director of the COVID-19 clinic.

Jennifer Chevinsky, MD, MPH, already had a deep understanding of long COVID when she landed in Riverside County, Calif., in the summer of 2021. She came from Atlanta, where as part of her job as an epidemic intelligence service officer at the CDC, she heard stories of COVID-19 patients who were not getting better.

Now she is a deputy public health officer for Riverside County, in a region known for its deserts, sizzling summer temperatures and diverse populations. She said her department has helped launch programs such as post–COVID-19 follow-up phone calls and long COVID training programs that reach out to the many Latino residents in this county of 2.4 million people. It also includes Black and Native American residents.

“We’re making sure information is circulated with community and faith-based organizations, and community health workers,” she said.

Ms. McCorkell said there is still much work to do to raise public awareness of the risks of long COVID and how to obtain care for patients. She would like to see a national public health campaign about long COVID, possibly spearheaded by the Centers for Disease Control and Prevention in partnership with local health workers and community-based organizations.

“That,” she said, “could make a big difference.”

Big-name hospital chains across the United States are opening dedicated centers to help patients dealing with long COVID. But so are the lower-profile clinics and hospitals run by cities, counties and states – including Harborview Medical Center in Seattle.

The Harborview clinic, operated by King County, is an example of how public health agencies are stepping up to treat people experiencing long COVID.

They serve areas ranging from Campbell County, Wyo., with 47,000 residents, to New York City, with its 8.4 million people. Many providers working there are searching for innovative ways to approach this lingering illness with its variety of symptoms, from brain fog to shortness of breath to depression and more.

Their efforts often fall below the radar, with still-scant serious media attention to long COVID or the public health employees working to treat ailing patients.

Why are state and local health agencies taking on these duties?

They’re leading the way in part because the federal government has made only limited efforts, said Lisa McCorkell, a cofounder of the Patient-Led Research Collaborative. The international group was founded in spring 2020 by researchers who are also long COVID patients.

“It’s a big reason why long COVID isn’t talked about as much,” Ms. McCorkell said. “It’s definitely a national issue. But it trickles down to state and local health departments, and there’s not enough resources.”

The government clinics may be accessible to people without insurance and often are cheaper than clinics at private hospitals.

Harborview has treated more than 1,000 patients with long COVID, and another 200 patients are awaiting treatment, said Jessica Bender, MD, a codirector of the University of Washington Post-COVID Rehabilitation and Recovery Clinic in Seattle’s First Hill neighborhood.

The group Survivor Corps offers lists by states of clinics. While the publicly run clinics may be less expensive or even free for some patients, methods of payment vary from clinic to clinic. Federally qualified health clinics offer treatment on a sliding scale. For instance, the Riverside University Health System in California has federally qualified centers. And other providers who are not federally qualified also offer care paid for on a sliding scale. They include Campbell County Health, where some residents are eligible for discounts of 25%-100%, said spokesperson Norberto Orellana.

At Harborview, Dr. Bender said the public hospital’s post-COVID clinic initially began with a staff of rehabilitation doctors but expanded in 2021 to include family and internal medicine doctors. And it offers mental health programs with rehabilitation psychologists who instruct on how to deal with doctors or loved ones who don’t believe that long COVID exists.

“I have patients who really have been devastated by the lack of support from coworkers [and] family,” Dr. Bender said.

In Campbell County, Wyo., the pandemic surge did not arrive in earnest until late 2021. Physical therapists at Campbell County’s Health Rehabilitation Services organized a rehabilitation program for residents with long COVID after recognizing the need, said Shannon Sorensen, rehabilitation director at Campbell County Health.

“We had patients coming in showing chest pain, or heart palpitations. There were people trying to get back to work. They were frustrated,” Ms. Sorensen said.

Myalgic encephalomyelitis and chronic fatigue syndrome activists have embraced the fight to recognize and help long COVID patients, noting the similarities between the conditions, and hope to help kickstart more organized research, treatment and benefits for long COVID sufferers and myalgic encephalomyelitis/chronic fatigue syndrome patients alike.

In Ft. Collins, Colo., disability activist Alison Sbrana has long had myalgic encephalomyelitis. She and other members of the local chapter of ME Action have met with state officials for several years and are finally seeing the results of those efforts.

Colorado Gov. Jared Polis has created the full-time position of policy adviser for long COVID and post–viral infection planning.

“This is one way forward of how state governments are (finally) paying attention to infection-triggered chronic illnesses and starting to think ahead on them,” Ms. Sbrana said.

A small increase in new cases brought COVID-19’s latest losing streak to an end at 4 weeks, based on data from the American Academy of Pediatrics and the Children’s Hospital Association.

After the 57% decline in cases seen during those 4 weeks of September, new cases rose by 3.7% during the week of Sept. 30 to Oct. 6. The 40,656 new cases reported bring the U.S. cumulative count of child COVID-19 cases to over 14.8 million since the pandemic began, which represents 18.4% of all cases, the AAP and CHA said in their weekly report based on state-level data.

The increase in new cases was not reflected in emergency department visits or hospital admissions, which both continued sustained declines that started in August. In the week from Sept. 27 to Oct. 4, the 7-day averages for ED visits with diagnosed COVID were down by 21.5% (age 0-11), 27.3% (12-15), and 18.2% (16-17), the Centers for Disease Control and Prevention said, while the most recent 7-day average for new admissions – 127 per day for Oct. 2-8 – among children aged 0-17 years with confirmed COVID was down from 161 per day the previous week, a drop of over 21%.

The state-level data that are currently available (several states are no longer reporting) show Alaska (25.5%) and Vermont (25.4%) have the highest proportions of cumulative cases in children, and Florida (12.3%) and Utah (13.5%) have the lowest. Rhode Island has the highest rate of COVID-19 per 100,000 children at 40,427, while Missouri has the lowest at 14,252. The national average is 19,687 per 100,000, the AAP and CHA reported.
 

Taking a look at vaccination

Vaccinations were up slightly in children aged 12-17 years, as 20,000 initial doses were given during the week of Sept. 29 to Oct. 5, compared with 17,000 and 18,000 the previous 2 weeks. Initial vaccinations in younger children, however, continued declines dating back to August, the AAP said in its weekly vaccination trends report.

The District of Columbia and Massachusetts have the most highly vaccinated groups of 12- to 17-year-olds, as 100% and 95%, respectively, have received initial doses, while Wyoming (39%) and Idaho (42%) have the lowest. D.C. (73%) and Vermont (68%) have the highest proportions of vaccinated 5- to 11-year-olds, and Alabama (17%) and Mississippi (18%) have the lowest. For children under age 5 years, those in D.C. (33%) and Vermont (26%) are the most likely to have received an initial COVID vaccination, while Alabama, Louisiana, and Mississippi share national-low rates of 2%, the AAP said its report, which is based on CDC data.

When all states and territories are combined, 71% of children aged 12-17 have received at least one dose of vaccine, as have 38.6% of all children 5-11 years old and 6.7% of those under age 5. Almost 61% of the nation’s 16- to 17-year-olds have been fully vaccinated, along with 31.5% of those aged 5-11 and 2.4% of children younger than 5 years, the CDC said on its COVID Data Tracker.

About 42 million children – 58% of the population under the age of 18 years – have not received any vaccine yet, the AAP noted. Meanwhile, CDC data indicate that 36 children died of COVID in the last week, with pediatric deaths now totaling 1,781 over the course of the pandemic.

Pregnant or postpartum women with disabilities are at relatively high risk of experiencing violence, often from the people closest to them, new research suggests.

The researchers set out to measure risk of interpersonal violence, which the World Health Organization defines as “the intentional use of physical force or power against an individual by an intimate partner, family member, or other community member.”

Hilary K. Brown, PhD, with the department of health & society, University of Toronto, led the study published online in Obstetrics and Gynecology.

Large, population-based dataset

The population study included people 15-49 years old with births in Ontario from 2004 to 2019. They included 147,414 people with physical disabilities; 47,459 people with intellectual disabilities; 2,557 with developmental disabilities; and 9,598 with multiple disabilities.

The control group was 1,594,441 million people without disabilities.

The outcome measured was “any emergency department visit, hospital admission, or death related to physical, sexual, or psychological violence between fertilization and 365 days post partum.”

Researchers found that the adjusted relative risk of interpersonal violence for those with disabilities, compared with those with no disabilities was 1.40 (95% confidence interval, 1.31-1.50) in those with physical disabilities; 2.39 (95% CI, 1.98-2.88) in those with intellectual or developmental disabilities; and 1.96 (95% CI, 1.66-2.30) in those with multiple disabilities.
 

History of violence means higher risk

Those with a history of interpersonal violence and a disability were at particularly high risk for perinatal violence.

The authors note that pregnancy is a high-risk period for interpersonal violence for all women, particularly by an intimate partner.

“More than 30% of intimate partner violence begins during pregnancy, and preexisting violence tends to escalate perinatally,” they write.

The authors cite previous research that found women with disabilities experience higher rates of abuse overall and by an intimate partner – two to four times rates reported by those without disabilities.
 

Opportunities for provider intervention

Since the period surrounding pregnancy is a time of increased contact with medical providers and resources, there may be opportunities for identifying abuse and providing interventions.

Those might include better screening, access to violence-related information and services, and education of health care professionals to support people with disabilities. For example, “Tools used for violence screening perinatally do not include items about forms of violence that are unique to individuals with disabilities, such as refusal to assist with activities of daily living.”

The authors add: “[G]iven that the strongest risk factor for interpersonal violence in the perinatal period, particularly in those with disabilities, was a prepregnancy history of interpersonal violence, our findings suggest that more could be done before pregnancy to offer screening and support at the index encounter.”
 

Violence can lead to adverse outcomes

Implications are important as the violence can result in barriers to care and adverse perinatal outcomes.

Jeanne L. Alhusen, PhD, CRNP, RN, University of Virginia Medical Center professor of nursing and associate dean for research, was not part of this research but wrote a paper earlier this year on the subject and had similar conclusions.

She said before this study by Brown et al., “our understanding of the risk of violence by disability type throughout the perinatal period, on a population-based level, was quite limited.”

With the size of this dataset, she said, this paper provides critical information for health care providers. It extends physicians’ ability to examine risk of violence by disability type as well as these patients’ risk of experiencing different types of violence.

She pointed out that the Pregnancy Risk Assessment Monitoring System (PRAMS) recently incorporated a disability supplement that allows better understanding of pregnancy risks in people with disabilities.

“It will be critical that U.S. states continue to incorporate the disability questions into their PRAMS administration [because] without that information, persons with disabilities will continue to experience unconscionable inequities,” she said.
 

Barriers to equitable care

Dr. Alhusen added that people with disabilities experience significant barriers in accessing equitable care – both at the provider and the system level.

She said it is critical that we recognize and address the sexual and reproductive health needs of all persons with disability. “This includes screening every person for violence and [ensuring] the tools we utilize are accessible and include items specific to disability-related abuse. In our qualitative studies, we have heard from pregnant persons that they were never screened or that they were screened with their abusive partner sitting next to them.”
 

Screening questions to ask

The American College of Obstetricians and Gynecologists provides examples of screening questions that are specific to people with disabilities such as asking if a partner has ever prevented the individual from using an assistive device (for example, a wheelchair, cane, or respirator) or refused to help with an important personal need, such as taking medication or getting out of bed.

“For many reasons, people with disabilities are less likely to disclose violence, and health care professionals are less likely to ask them about it,” said coauthor of the current study, Yona Lunsky, PhD, clinician-scientist, Centre for Addiction and Mental Health, Toronto, in a statement. Based on the findings, she said, she hopes clinicians will see the need to develop disability-informed screening tools to capture abuse and identify the appropriate resources for this population before, during, and after pregnancy.

The authors add: “[G]iven that the strongest risk factor for interpersonal violence in the perinatal period, particularly in those with disabilities, was a prepregnancy history of interpersonal violence, our findings suggest that more could be done before pregnancy to offer screening and support at the index encounter.”
 

Violence can lead to adverse outcomes

Implications are important as the violence can result in barriers to care and adverse perinatal outcomes.

Jeanne L. Alhusen, PhD, CRNP, RN, University of Virginia Medical Center professor of nursing and associate dean for research, was not part of this research but wrote a paper earlier this year on the subject and had similar conclusions.

She said before this study by Brown et al., “our understanding of the risk of violence by disability type throughout the perinatal period, on a population-based level, was quite limited.”

With the size of this dataset, she said, this paper provides critical information for health care providers. It extends physicians’ ability to examine risk of violence by disability type as well as these patients’ risk of experiencing different types of violence.

She pointed out that the Pregnancy Risk Assessment Monitoring System (PRAMS) recently incorporated a disability supplement that allows better understanding of pregnancy risks in people with disabilities.

“It will be critical that U.S. states continue to incorporate the disability questions into their PRAMS administration [because] without that information, persons with disabilities will continue to experience unconscionable inequities,” she said.
 

Barriers to equitable care

Dr. Alhusen added that people with disabilities experience significant barriers in accessing equitable care – both at the provider and the system level.

She said it is critical that we recognize and address the sexual and reproductive health needs of all persons with disability. “This includes screening every person for violence and [ensuring] the tools we utilize are accessible and include items specific to disability-related abuse. In our qualitative studies, we have heard from pregnant persons that they were never screened or that they were screened with their abusive partner sitting next to them.”
 

Screening questions to ask

The American College of Obstetricians and Gynecologists provides examples of screening questions that are specific to people with disabilities such as asking if a partner has ever prevented the individual from using an assistive device (for example, a wheelchair, cane, or respirator) or refused to help with an important personal need, such as taking medication or getting out of bed.

“For many reasons, people with disabilities are less likely to disclose violence, and health care professionals are less likely to ask them about it,” said coauthor of the current study, Yona Lunsky, PhD, clinician-scientist, Centre for Addiction and Mental Health, Toronto, in a statement. Based on the findings, she said, she hopes clinicians will see the need to develop disability-informed screening tools to capture abuse and identify the appropriate resources for this population before, during, and after pregnancy.

People who develop long COVID may be responding more strongly to a non–SARS-CoV-2 virus they encountered in the past than to SARS-CoV-2, a study by researchers at Harvard Medical School suggests.

Long COVID, also called postacute sequelae of COVID-19 (PASC), causes various symptoms that persist at least 4 weeks after the initial SARS-CoV-2 infection, they write in the preprint server medRxiv. Four authors explained their research into possible mechanisms of long COVID in an interview.

“Immunity to non-COVID endemic coronaviruses may play a role in who develops PASC,” co–lead author Jonathan D. Herman, MD, PhD, said. “There’s still so much more we need to understand, but it is striking that back-boosting of immune responses to coronavirus OC43 was uniquely enriched in individuals with PASC.”

“In the study, individuals with PASC preferentially generated stronger responses to previously encountered cold-causing coronaviruses,” co–senior author Galit Alter, PhD, said.

“Instead of generating strong SARS-CoV-2 immunity, they bolstered a response to a different coronavirus, potentially making their response less effective in clearing SARS-CoV-2. Surprisingly, most of the individuals had been vaccinated – and they still maintained this unusual antibody response – pointing to new therapeutic pathways to treat PASC,” Dr. Alter said.
 

Humoral immunity offers a clue to long-COVID origins

One-fifth of COVID-19 patients progress to long COVID, but which patients develop PASC and why are not well understood, the authors write.

“Antibodies represent powerful biomarkers that have been used for decades to diagnose disease. However, antibodies also provide a powerful source of information on previous infections. The use of antibody profiling, here, pointed to the presence of incomplete antibody responses to SARS-CoV-2 in individuals with PASC,” Dr. Alter said.

The researchers reviewed the medical records of patients in the Mass General Brigham health care system in Boston, including referrals from rheumatologists of participants diagnosed with COVID-19 outside the MGB system, starting on March 1, 2020.

They focused on patients with systemic autoimmune rheumatic diseases (SARDs) because their tendency toward inflammation and autoantibody production may make them more susceptible to PASC and enrich for specific inflammatory-driven endotypes.

All 43 participants had COVID-19 without hospital admission and SARDs. Patients treated only for fibromyalgia, osteoarthritis, mechanical back pain, gout, or pseudogout without a SARD were excluded from the study.

Overall, 79% of participants were female, 35% had rheumatoid arthritis, 19% had psoriatic arthritis, and 95% had received a COVID-19 vaccine.

The researchers used systems serology to perform comprehensive antibody profiling against SARS-CoV-2 and a panel of endemic pathogens or routine vaccine antigens.
 

Long-COVID patients had a distinct immune response

Overall, 17 patients developed PASC and 26 did not, and in those with PASC, they found a distinct humoral immune response. Patients with PASC:

• harbored less inflamed and weaker Fc-gamma receptor–binding anti–SARS-CoV-2 antibodies;
• showed a significantly expanded and more inflamed antibody response against endemic coronavirus OC43; and
• mounted more avid IgM responses and developed expanded inflammatory OC43 S2–specific Fc-receptor–binding responses, which were linked to cross reactivity across SARS-CoV-2 and common coronaviruses.

“Strengths of the study include the detailed phenotypes of cases after COVID-19, particularly to classify PASC presence or absence, as well as the depth and breadth of antibody profiling. This allowed us to identify a humoral immune signature of PASC,” said co–senior author Jeffrey A. Sparks, MD, MMSc.

“However, the study was limited in its size to investigate different types of PASC, such as fatigue or lung symptoms, that may have biologic differences. Also, all patients in the study had a preexisting rheumatic disease,” he acknowledged.

“A substantial portion of patients with COVID-19 will develop PASC, which can have substantial impact on health and quality of life,” said co–senior author Zachary S. Wallace, MD, MS. “Given the higher risk of COVID-19 in many patients with rheumatic disease, it is important to understand the etiology of PASC in this vulnerable population, to enable future diagnostic and therapeutic advances.”

Davey Smith, MD, professor of medicine and head of infectious diseases and global public health at the University of California, San Diego, in La Jolla, who was not involved in the study, called the findings interesting even though the results will not immediately affect patient care.

“There may be a link between previous non–SARS-CoV-2 coronavirus infection and PASC,” he added. “Perhaps, by understanding why some people do and do not get PASC, we can develop treatments for the condition.

“This paper is a preprint and will need to go through peer review,” Dr. Smith said. “There are many elements that need to be scrutinized. For example, there is no definition of PASC that is universally accepted, so how did that play into this study?”

Mark Cameron, PhD, associate professor in the department of population and quantitative health sciences at Case Western Reserve University, Cleveland, called this a strong study from a strong group, although it is a preprint prior to peer review.

“In this initial study, the scientists focused on people who had rheumatic disease before getting COVID-19, knowing they are at higher risk for lasting complications and hopefully are more immunologically similar when diagnosed with long COVID – a single ‘endotype’ or group of patients with similar clinical symptoms and background,” he noted.

“Our immune system’s memory sometimes fails to effectively fight a new virus that looks too much like a virus it saw before. This ineffective immune response can set up various problems, including the poor recoveries we see in people with long COVID,” he said.

“OC43 probably emerged in the late 1800s and probably caused a pandemic of severe respiratory illness between 1889 and 1890, previously thought to be a flu,” Dr. Cameron recalled. “OC43 is still around as an endemic coronavirus, usually causing mild or moderate upper-respiratory infections.”

COVID-19 immunity is complex, and previous SARS-CoV-2 infection doesn’t guarantee we won't get COVID-19 again, especially as new variants emerge, added Dr. Cameron, who also was not involved in the study.

“This study may help us better understand the risks and possible mechanisms associated with COVID-19 and long COVID in the face of previous coronavirus infections,” he said. “It may also help guide future COVID-19 therapies and vaccines.”

The authors plan further related research.

The study received grant support and an anonymous donation. Dr. Alter, Dr. Sparks, and Dr. Wallace report financial relationships with the pharmaceutical industry. All other authors, and Dr. Davey and Dr. Cameron, report no conflicts of interest with the study. All experts commented by email.
