Rise in number of unclaimed dead bodies used in medical schools
An increasing number of unclaimed dead bodies went to help train medical students in Texas between 2017 and 2021, new research reveals.
Investigators did not expect to see such an increase, said lead author Eli Shupe, PhD, assistant professor in the department of philosophy and humanities at the University of Texas at Arlington.
The numbers jumped from 64 unclaimed bodies to 446 bodies annually over those 5 years. “People are usually under the impression that this is something that either doesn’t happen anymore or it’s on the decline as more people step up to be willed body donors,” said Dr. Shupe, who is also codirector of the medical humanities and bioethics program at UTA.
The study findings were published in JAMA as a research letter. Researchers said that the number of unclaimed bodies – those not claimed by next of kin for burial or cremation – has dropped significantly across the United States since the middle of the 20th century.
Some people don’t want to discuss the practice because it is controversial, said Matthew DeCamp, MD, PhD, associate professor at the Center for Bioethics and Humanities and Division of General Internal Medicine, University of Colorado Anschutz Medical Campus, Aurora. “But ‘sweeping it under the rug’ means we miss the opportunity for dialogues about respect, consent, social justice, and so on – as well as the opportunity to change policy.”
The study included all medical schools in Texas, and researchers say it’s likely happening elsewhere in the United States and abroad. The practice is legal in most counties and states. One exception is New York, which passed a law in 2016 that does not allow unclaimed bodies to go to medical schools without prior written consent from the deceased.
“Although limited to one state, these findings suggest that use of unclaimed bodies may be both more common than we thought and increasing,” added Dr. DeCamp, who was not affiliated with the current study.
Even doctors can be split on the value to medical training versus the rights of the dead. “I know that medical professionals are divided on the role of dissection and anatomy learning and its necessity,” Dr. Shupe said. She predicted working with cadavers in medical schools will probably continue for the foreseeable future.
The marginalized and the vulnerable
So who are the unclaimed? They can include those who are unhoused and those who do not leave enough money to cover cost of burial or cremation. In some cases, they don’t have a next of kin or their next of kin is unwilling or unable to pay for their burial or cremation.
“Predominantly, these are going to be people who are poor or members of marginalized or vulnerable populations,” Dr. Shupe said. She estimated that about 80% of the people who die in poverty in her region, the Dallas–Fort Worth area, are Black or Hispanic individuals.
“It is alarming that we are going in the wrong direction when it comes to the increasing utility of unclaimed bodies,” said Joy Balta, PhD, associate professor of anatomy and founding director of Anatomy Learning Institute at Point Loma Nazarene University, San Diego, when asked to comment on the study. The hope is to rely solely on donated human bodies to ensure that donors have provided informed consent for their use in education, research, and clinical training.
“These unclaimed bodies did not provide any consent, [which] raises ethical questions,” Dr. Balta said.
Key findings
In Texas in 2021, 43% of the cadavers in 14 medical schools studied came from unclaimed bodies. A total 14% of schools reported that they accepted unclaimed bodies, 28% possibly accepted them because they were transferred from institutions that use them, and the remaining 57% do not accept unclaimed bodies.
The total number and proportion of unclaimed bodies going to medical education in the study increased during the study. The 14% in 2021 was a jump from 2% in 2017, for example.
The 14 medical schools studied included both public and private institutions. The investigators also looked at data from the Texas State Anatomical Board, which tracks how cadavers are attained and distributed in the state, including how many began as unclaimed bodies.
Legal in most jurisdictions
Dr. Shupe first learned about what can happen to unclaimed bodies as a hospice volunteer. She was accompanying the hospice chaplain one day who said: “Poor Mr. Smith [not his real name] doesn’t have long, and then he’s off to the medical school.” Dr. Shupe asked what the chaplain meant because she was unaware of the practice.
“I stumbled on this by chance, and it ended up being a really fruitful research area,” she added.
The bigger picture
Greater awareness is needed and there is not a lot of research out there, Dr. Shupe said. One exception is a 2018 study of medical schools nationwide that found 12.4% reported possible use of unclaimed bodies.
Dr. DeCamp, an author of that previous research, said: “Knowing this practice continues is the most important thing for doctors and medical students to know.”
It remains unclear whether the COVID pandemic or the opioid epidemic contributed to the rise of unclaimed bodies going to medical training. That is a question for future study, Dr. Shupe said.
Most bodies willingly donated
The majority of cadavers that go to medical training in the United States are ‘full body donors,’ people or relatives who agree to voluntarily send a body to medical schools. “We are fortunate to have a lot of people who are willing to become whole body donors,” she said.
Greater awareness about how donated cadavers could make a difference to further increase willful donations, Dr. Shupe said. “Honoring those gifts by allowing them to help train the next generation of doctors is a wonderful thing.”
A May 2023 study from Dr. Balta and colleagues on body donation programs in the United States “found that the number of whole-body donations have decreased in some states and the numbers are not enough to meet the needs for education, research and clinical training,” Dr. Balta said. This could explain the increasing use of unclaimed bodies.
“Some medical schools have explicit educational interventions on this topic, and formally recognize the unclaimed at anatomical gift ceremonies,” Dr. DeCamp said. “More should.”
Research support was provided by the UTA. Dr. Shupe, Dr. Balta, and Dr. DeCamp reported no relevant financial relationships.

Hold Ozempic before surgery to optimize patient safety?
Semaglutide and related drugs for weight loss have co-opted bariatric medicine in recent months. They have also raised serious questions for hospital-based clinicians who wonder whether the drugs may pose risks to surgery patients undergoing anesthesia.
weight loss.
Ozempic is indicated for treating type 2 diabetes but also is prescribed off-label for weight loss. Other GLP-1 agents from Novo Nordisk, Wegovy (semaglutide) and Saxenda (liraglutide) injections, are Food and Drug Administration–approved for weight loss. These medications work by decreasing hunger and lowering how much people eat. Semaglutide also is available as a once-daily tablet for type 2 diabetes (Rybelsus).
The American Society of Anesthesiologists (ASA) has been working on guidance on the drugs. “It’s a really hot issue now. We are getting emails from our members looking for guidance,” ASA president Michael Champeau, MD, said in an interview.
But despite the interest in how the medications might affect surgery patients and interact with anesthesia, relatively little evidence exists in the literature beyond case studies. So the society is not issuing official recommendations at this point.
“We’re going to just be calling it ‘guidance’ for right now because of the paucity of the scientific literature,” said Dr. Champeau, adjunct clinical professor of anesthesiology, perioperative, and pain medicine at Stanford (Calif.) University. “It’s probably not going to have words like ‘must; it will probably have words like ‘should’ or ‘should consider.’ “
The ASA guidance could be out in written form soon, Dr. Champeau added.
Meanwhile, whether physicians should advise stopping these medications 24 hours, 48 hours, or up to 2 weeks before surgery remains unknown.
In search of some consensus, John Shields, MD, an orthopedic surgeon at Atrium Health Wake Forest Baptist Davie Medical Center in Bermuda Run, N.C., asked colleagues on #MedTwitter: “Anyone have guidelines for ozempic around time of surgery? – holding med? – how long NPO?”
Because a full stomach can interfere with anesthesia, clinicians often advise people to stop eating and drinking 12-24 hours before elective procedures (NPO). In the case of once-weekly GLP-1 injections, which can slow gastric emptying, the optimal timeframe remains an open question. The main concern is aspiration, where a patient actively vomits while under anesthesia or their stomach contents passively come back up.
Dr. Shields’ Twitter post garnered significant reaction and comments. Within 4 days, the post was retweeted 30 times and received 72 replies and comments. Dr. Shields noted the general consensus was to hold semaglutide for 1-2 weeks before a procedure. Other suggestions included recommending a liquid diet only for 24-48 hours before surgery, recommending an NPO protocol 24-36 hours in advance, or adjusting the weekly injection so the last dose is taken 5-6 days before surgery.
Anesthesiologist Cliff Gevirtz, MD, has encountered only a few surgical patients so far taking a GLP-1 for weight loss. “And thankfully no aspiration,” added Dr. Gevirtz, clinical director of office-based ambulatory anesthesia services at Somnia Anesthesia in Harrison, N.Y.
To minimize risk, some physicians will perform an ultrasound scan to assess the contents of the stomach. If surgery is elective in a patient with a full stomach, the procedure can get postponed. Another option is to proceed with the case but treat the patient as anesthesiologists approach an emergency procedure. To be safe, many will treat the case as if the patient has a full stomach.
Dr. Gevirtz said he would treat the patient as a ‘full stomach’ and perform a rapid sequence induction with cricoid pressure. He would then extubate the patient once laryngeal reflexes return.
A rapid-sequence induction involves giving the medicine that makes a patient go to sleep, giving another medicine that paralyzes them quickly, then inserting a breathing tube – all within about 30 seconds. Cricoid pressure involves pushing on the neck during intubation to try to seal off the top of the esophagus and again minimize the chances of food coming back up.
Giving metoclopramide 30 minutes before surgery is another option, Dr. Gevirtz said. Metoclopramide can hasten the emptying of stomach contents. Administration in advance is important because waiting for the drug to work can prolong time in the operating room.
Is holding semaglutide before surgery a relevant clinical question? “Yes, very much so,” said Ronnie Fass, MD, division director of gastroenterology and hepatology and the medical director of the Digestive Health Center at The MetroHealth System in Cleveland.
Dr. Fass recommended different strategies based on the semaglutide indication. Currently, clinicians at MetroHealth instruct patients to discontinue diabetic medications the day of surgery. For those who take semaglutide for diabetes, and because the medication is taken once a week, “there is growing discussion among surgeons that the medication should not be stopped prior to surgery. This is to ensure that patients’ diabetes is well controlled before and during surgery,” Dr. Fass said.
In patients taking semaglutide for weight loss only, “there is no clear answer at this point,” he said.
Dr. Fass said the question is complicated by the fact that the medication is taken once a week. “It brings up important questions about the use of the medication during surgery, which may increase the likelihood of side effects in general and for certain types of surgery. Personally, if a patient is taking [semaglutide] for weight loss only, I would consider stopping the medication before surgery.”
The ASA was able to act quickly because it already had an expert task force review how long people should fast before surgery last year – before the explosion in popularity of the GLP-1 agonists.
Although it is still a work in progress, Dr. Champeau offered “a peek” at the recommendations. “The guidance is going to look at how far in advance the drugs should be stopped, rather than looking at making people fast even longer” before surgery, he said. “There’s just no data on that latter question.”

Giving metoclopramide 30 minutes before surgery is another option, Dr. Gevirtz said. Metoclopramide can hasten the emptying of stomach contents. Administration in advance is important because waiting for the drug to work can prolong time in the operating room.
Is holding semaglutide before surgery a relevant clinical question? “Yes, very much so,” said Ronnie Fass, MD, division director of gastroenterology and hepatology and the medical director of the Digestive Health Center at The MetroHealth System in Cleveland.
Dr. Fass recommended different strategies based on the semaglutide indication. Currently, clinicians at MetroHealth instruct patients to discontinue diabetic medications the day of surgery. For those who take semaglutide for diabetes, and because the medication is taken once a week, “there is growing discussion among surgeons that the medication should not be stopped prior to surgery. This is to ensure that patients’ diabetes is well controlled before and during surgery,” Dr. Fass said.
In patients taking semaglutide for weight loss only, “there is no clear answer at this point,” he said.
Dr. Fass said the question is complicated by the fact that the medication is taken once a week. “It brings up important questions about the use of the medication during surgery, which may increase the likelihood of side effects in general and for certain types of surgery. Personally, if a patient is taking [semaglutide] for weight loss only, I would consider stopping the medication before surgery.”
The ASA was able to act quickly because it already had an expert task force review how long people should fast before surgery last year – before the explosion in popularity of the GLP-1 agonists.
Although it is still a work in progress, Dr. Champeau offered “a peek” at the recommendations. “The guidance is going to look at how far in advance the drugs should be stopped, rather than looking at making people fast even longer” before surgery, he said. “There’s just no data on that latter question.”

Nearly one in three patients with IBD affected by skin lesions
People with inflammatory bowel disease (IBD) commonly develop skin lesions linked to their condition, but until now few researchers looked at how common they are.
“Skin lesions in IBD patients are much more prevalent than it is generally accepted. The lesions may be related to the pathogenesis of IBD, but it is very important to know that the modern biological therapies may also cause skin lesions,” said senior study author Laimas Jonaitis, MD, PhD, professor in the department of gastroenterology at Lithuanian University of Health Sciences in Kaunas.
“If the gastroenterologist is experienced and has enough competence, he or she may establish the diagnosis, but in all other cases it is wise and advisable to refer the patient to the dermatologist,” Dr. Jonaitis said. A referral should include the history and full treatment for IBD.
The results were presented as a poster at the annual congress of the European Crohn’s and Colitis Organisation, held in Copenhagen and virtually.
Dr. Jonaitis and colleagues conducted a literature analysis to determine the prevalence of extra-abdominal manifestations of IBD. The lack of published data prompted them to survey 152 consecutive patients with IBD receiving outpatient treatment at their institution. The patients completed questionnaires from January to October 2022 about any cutaneous lesions.
The mean age of patients was 42 years, and 58% were men. A majority, 72%, had ulcerative colitis, and 28% had Crohn’s disease.
Prevalence of skin lesions
A total of 43% of participants reported skin lesions, but only 30% of patients had lesions considered related to IBD or IBD therapy due to their emergence after the patient’s IBD diagnosis.
By IBD diagnosis, 29% of patients with ulcerative colitis and 33% of patients with Crohn’s disease had lesions related to their condition. The difference in skin lesion prevalence between the two groups was not significant (P > .05), the researchers noted.
The team further investigated the types of skin lesions deemed to be associated with IBD or IBD therapy.
Overall, they found psoriasis in nine patients, eczema in nine, erythema nodosum in six, pyoderma gangrenosum in five, allergic rash in four, and vitiligo in two. They found acne, epidermolysis bullosa acquisita, and hemorrhagic vasculitis in one patient each.
Specifically, among patients with ulcerative colitis, skin lesions were reported in 8 of 27 with left-sided colitis, 2 of 15 with ulcerative colitis proctitis, and 22 of 67 patients with pancolitis. The difference between the groups of proctitis and pancolitis was significant (P = .03).
Within the group with Crohn’s disease, skin lesions were reported in 3 of 15 patients with ileitis, 4 of 10 with colitis, and 7 of 17 with ileocolitis. The difference among these groups was not significant (P > .05).
The most common skin lesions observed in Crohn’s disease were erythema nodosum and eczema, and in ulcerative colitis, psoriasis and eczema, the researchers reported.
They also noted that the cutaneous lesions were significantly more prevalent in extensive ulcerative colitis compared with distal disease.
Skin lesions add to patient misery
“Skin lesions are considered a burden to patients with IBD and add to their suffering,” said Sara Mesilhy, MBBS, a gastroenterologist with the Royal College of Physicians in the United Kingdom, who was not affiliated with the research.
The severity and location of the disease appears to play a role because researchers found extensive ulcerative colitis may carry a higher risk for the development of skin lesions, Dr. Mesilhy noted.
The first step when facing skin lesions is to control the disease activity via the best treatment option, Dr. Mesilhy suggested.
The study was independently supported. Dr. Jonaitis and Dr. Mesilhy have disclosed no relevant financial relationships.

AI-assisted colonoscopy in IBD: Not all it’s cut out to be?
Within the rising tide of studies extolling the benefits of artificial intelligence for improving adenoma detection during colonoscopy comes new research suggesting the contrary, at least among people with inflammatory bowel disease (IBD).
Researchers retrospectively studied almost 1,000 colonoscopies before and after introduction of an AI system (GI Genius, Medtronic) at a tertiary medical center in Israel in which a large volume of endoscopies was performed.
The lower ADR rate in AI-assisted procedures could be the result of an overreliance on the AI technology and shorter procedure times, which may have led to an underrecognition of adenomas, lead investigator Asaf Levartovsky, MD, said in an interview.
“AI is an aid to the endoscopist, not a replacement to the endoscopist,” added Dr. Levartovsky, a gastroenterologist at Sheba Medical Center, Tel Aviv.
The results were presented as a poster at the annual congress of the European Crohn’s and Colitis Organisation, held in Copenhagen and virtually.
Key findings
The use of AI has recently been shown to improve colorectal cancer screening overall, the authors note. ADR is a measure of the quality of screening colonoscopies. Detection rates were at least 20% among women and 30% among men, “indicative of adequate performance.”
The ADR for people with IBD can be lower than it is for average-risk patients, however, owing to a difference in age in the two populations and the presence of dysplasia-associated lesions, as opposed to sporadic adenomas, for patients with IBD, the researchers note. There is no consensus on an acceptable ADR target for patients with IBD, and the impact of AI-assisted colonoscopy in this patient population hasn’t been explored, they add.
To learn more, Dr. Levartovsky and colleagues compared 237 screening colonoscopies conducted in the 11 months before AI was introduced at the medical center in July 2021 to 759 colonoscopies performed in the 15 months after its introduction.
The pre-AI patient group and the AI patient group were similar (mean age, 44-45 years; about 55% men in each group). Crohn’s disease was more common than ulcerative colitis (63% in the pre-AI cohort and 57% in the AI-assisted cohort).
The ADR in the pre-AI group was 6.3%, compared with 4% in the AI-assisted group (P = .15). The distinction became significant, at 7.6% versus 3.8% (P = .035), when researchers evaluated colonoscopies performed by gastroenterologists who had 5 or more years of experience.
Total procedure time was longer for the patients in the pre-AI group, at 25 minutes, compared with 21 minutes in the AI-assisted group. This difference was statistically significant (P < .0001).
“I think this poster raises questions regarding the real-world utility of AI for adenoma detection [in patients with IBD],” Dr. Levartovsky said.
Dr. Levartovsky said he was not surprised by their findings, because they are similar to those reported in a recent article from his group, although this earlier study did not focus on patients with IBD.
The research had some limitations. The study was not case-control matched, and the pre-AI group was considerably smaller than the AI group.
Study design a factor
The study design could account for the difference in its findings, compared with research indicating that AI-assisted colonoscopies improve ADR, Cesare Hassan, MD, associate professor of gastroenterology at Humanitas University, Milan, said in an interview.
The study was retrospective, so researchers could not randomly assign people to the AI or the no-AI group. It therefore was not possible to ensure that the prevalence of disease was equivalent between the two groups, he said.
By comparison, the previous studies showing the benefits of AI-assisted colonoscopy with regard to ADR were randomized, controlled clinical trials, Dr. Hassan said.
The study was independently supported. Dr. Levartovsky and Dr. Hassan report no relevant financial relationships.

Mental health risks higher among young people with IBD
, a new U.K. study suggests.
The retrospective, observational study of young people with IBD versus those without assessed the incidence of a wide range of mental health conditions in people aged 5-25 years.
“Anxiety and depression will not be a surprise to most of us. But we also saw changes for eating disorders, PTSD, and sleep changes,” said Richard K. Russell, MD, a pediatric gastroenterologist at the Royal Hospital for Sick Children, Edinburgh.
Dr. Russell presented the research at the annual congress of the European Crohn’s and Colitis Organisation, held in Copenhagen and virtually.
The findings indicate an unmet need for mental health care for young patients with IBD, he said. “All of us at ECCO need to address this gap.”
Key findings
Dr. Russell and colleagues identified 3,898 young people diagnosed with IBD in the 10-year period Jan. 1, 2010, through Jan. 1, 2020, using the Optimum Patient Care Research Database, which includes de-identified data from more than 1,000 general practices across the United Kingdom. They used propensity score matching to create a control group of 15,571 people without IBD, controlling for age, sex, socioeconomic status, ethnicity, and health conditions other than IBD.
Median follow-up was about 3 years.
The cumulative lifetime risk for developing any mental health condition by age 25 was 31.1% in the IBD group versus 25.1% in controls, a statistically significant difference.
Compared with the control group, the people with incident IBD were significantly more likely to develop the following:
- PTSD.
- Eating disorders.
- Self-harm.
- Sleep disturbance.
- Depression.
- Anxiety disorder.
- ‘Any mental health condition.’
Those most are risk included males overall, and specifically boys aged 12-17 years. Those with Crohn’s disease versus other types of IBD were also most at risk.
In a subgroup analysis, presented as a poster at the meeting, Dr. Russell and colleagues also found that mental health comorbidity in children and young adults with IBD is associated with increased IBD symptoms and health care utilization, as well as time off work.
Children and young adults with both IBD and mental health conditions should be monitored and receive appropriate mental health support as part of their multidisciplinary care, Dr. Russell said.
Dr. Russell added that the study period ended a few months before the COVID-19 pandemic began, so the research does not reflect its impact on mental health in the study population.
“The number of children and young adults we’re seeing in our clinic with mental health issues has rocketed through the roof because of the pandemic,” he said.
Dr. Russell suggested that the organization create a psychology subgroup called Proactive Psychologists of ECCO, or Prosecco for short.
Clinical implications
The study is important for highlighting the increased burden of mental health problems in young people with IBD, said session comoderator Nick Kennedy, MD, a consultant gastroenterologist and chief research information officer with the Royal Devon University Healthcare NHS Foundation Trust in England.
Dr. Kennedy, who was not affiliated with the research, is also supportive of the idea of a psychological subgroup within ECCO.
The peak age for developing mental health disorders found by the study (12-17 years) “is a unique and very sensitive time,” said Sara Mesilhy, MBBS, a gastroenterologist with the Royal College of Physicians in London.
“These results highlight the need for development of early screening psychiatric programs starting from time of diagnosis and continuing on periodic intervals to offer the best management plan for IBD patients, especially those with childhood-onset IBD,” said Dr. Mesilhy, who was not affiliated with the research.
Such programs would “improve the patient’s quality of life, protecting them from a lot of suffering and preventing the bad sequelae for these disorders,” said Dr. Mesilhy. “Moreover, we still need further studies to identify the most efficient monitoring and treatment protocols.”
Dr. Kennedy applauded the researchers for conducting a population-based study because it ensured an adequate cohort size and maximized identification of mental health disorders.
“It was interesting to see that there were a range of conditions where risk was increased, and that males with IBD were at particularly increased risk,” he added.
Researchers’ use of coded primary care data was a study limitation, but it was “appropriately acknowledged by the presenter,” Dr. Kennedy said.
The study was supported by Pfizer. Dr. Russell disclosed he is a consultant and member of a speakers’ bureau for Pfizer outside the submitted work. Dr. Kennedy and Dr. Mesilhy report no relevant financial relationships.

Dr. Russell presented the research at the annual congress of the European Crohn’s and Colitis Organisation, held in Copenhagen and virtually.
The findings indicate an unmet need for mental health care for young patients with IBD, he said. “All of us at ECCO need to address this gap.”
Key findings
Dr. Russell and colleagues identified 3,898 young people diagnosed with IBD in the 10-year period Jan. 1, 2010, through Jan. 1, 2020, using the Optimum Patient Care Research Database, which includes de-identified data from more than 1,000 general practices across the United Kingdom. They used propensity score matching to create a control group of 15,571 people without IBD, controlling for age, sex, socioeconomic status, ethnicity, and health conditions other than IBD.
Median follow-up was about 3 years.
The cumulative lifetime risk for developing any mental health condition by age 25 was 31.1% in the IBD group versus 25.1% in controls, a statistically significant difference.
Compared with the control group, the people with incident IBD were significantly more likely to develop the following:
- PTSD.
- Eating disorders.
- Self-harm.
- Sleep disturbance.
- Depression.
- Anxiety disorder.
- ‘Any mental health condition.’
Those most are risk included males overall, and specifically boys aged 12-17 years. Those with Crohn’s disease versus other types of IBD were also most at risk.
In a subgroup analysis, presented as a poster at the meeting, Dr. Russell and colleagues also found that mental health comorbidity in children and young adults with IBD is associated with increased IBD symptoms and health care utilization, as well as time off work.
Children and young adults with both IBD and mental health conditions should be monitored and receive appropriate mental health support as part of their multidisciplinary care, Dr. Russell said.
Dr. Russell added that the study period ended a few months before the COVID-19 pandemic began, so the research does not reflect its impact on mental health in the study population.
“The number of children and young adults we’re seeing in our clinic with mental health issues has rocketed through the roof because of the pandemic,” he said.
Dr. Russell suggested that the organization create a psychology subgroup called Proactive Psychologists of ECCO, or Prosecco for short.
Clinical implications
The study is important for highlighting the increased burden of mental health problems in young people with IBD, said session comoderator Nick Kennedy, MD, a consultant gastroenterologist and chief research information officer with the Royal Devon University Healthcare NHS Foundation Trust in England.
Dr. Kennedy, who was not affiliated with the research, is also supportive of the idea of a psychological subgroup within ECCO.
The peak age for developing mental health disorders found by the study (12-17 years) “is a unique and very sensitive time,” said Sara Mesilhy, MBBS, a gastroenterologist with the Royal College of Physicians in London.
“These results highlight the need for development of early screening psychiatric programs starting from time of diagnosis and continuing on periodic intervals to offer the best management plan for IBD patients, especially those with childhood-onset IBD,” said Dr. Mesilhy, who was not affiliated with the research.
Such programs would “improve the patient’s quality of life, protecting them from a lot of suffering and preventing the bad sequelae for these disorders,” said Dr. Mesilhy. “Moreover, we still need further studies to identify the most efficient monitoring and treatment protocols.”
Dr. Kennedy applauded the researchers for conducting a population-based study because it ensured an adequate cohort size and maximized identification of mental health disorders.
“It was interesting to see that there were a range of conditions where risk was increased, and that males with IBD were at particularly increased risk,” he added.
Researchers’ use of coded primary care data was a study limitation, but it was “appropriately acknowledged by the presenter,” Dr. Kennedy said.
The study was supported by Pfizer. Dr. Russell disclosed he is a consultant and member of a speakers’ bureau for Pfizer outside the submitted work. Dr. Kennedy and Dr. Mesilhy report no relevant financial relationships.

DNA panels could predict endoscopic response to biologics in Crohn’s disease
Prescribing a biologic for people with Crohn’s disease is a complicated process that includes consideration of previous therapy, the severity of disease, cost, and other factors. Missing, however, has been the ability to accurately predict endoscopic response to a specific biologic agent to guide choice of therapy.
Although the biomarker panels are not yet clinically available, researchers demonstrated that they are accurate, valid, stable over time, and largely specific to each of the three biologic agents.
“Evidence over the last 10 years has shown a consistent difference in DNA methylation between people with IBD [inflammatory bowel disease] and healthy controls. Many of these studies suggest a role for DNA methylation for treatment response prediction,” Vincent Joustra, PhD, said when presenting results of the EPIC-CD trial at the annual congress of the European Crohn’s and Colitis Organisation.
After comparing endoscopic responders to nonresponders in different datasets. researchers found that “DNA methylation profiles are, in fact, associated with response to adalimumab, vedolizumab, and ustekinumab,” added Dr. Joustra, visiting fellow in the department of gastroenterology and hepatology at Amsterdam University Medical Centers.
DNA methylation – the presence or absence of a methyl group on a specific DNA location called a CpG – does not change a person’s genotype. Rather, the methylation process either activates or deactivates a gene’s expression. It can be used to predict treatment response.
Within the past 2 decades, “biologics have revolutionized care of IBD patients. Yet, despite their clinical efficacy, treatment choice is currently based on trial and error, which is suboptimal,” Dr. Joustra said.
Adding biomarkers to improve biologic medication selection is “urgently needed,” he added. “However, such biomarkers are not available for practice today.”
Methylation methodology
Dr. Joustra and colleagues prospectively studied DNA methylation in the peripheral blood samples of 184 adults with Crohn’s disease. They compared the biomarkers at baseline in people set to start biologic therapy and again at a median of 28 weeks following treatment with adalimumab (58 patients), vedolizumab (64 patients), and ustekinumab (62 patients).
Participants were divided into a discovery cohort to identify relevant biomarkers and a validation cohort to confirm the findings. Results were validated against a separate cohort of patients at Oxford (England) University.
Response was strictly defined as a decrease of at least 50% in a simple endoscopic score for Crohn’s disease, corticosteroid-free clinical response or remission using the Harvey Bradshaw Index, and/or biochemical response or remission.
Before patients were treated, the investigators created three epigenetic panels. The CpG loci of interest were identified using the Infinium MethylationEPIC BeadChip array, which measures over 850,000 CpG sites across the whole genome.
Key findings
One epigenetic panel featured 100 CpG loci relevant for adalimumab that correlated to an “endoscopic response with high accuracy,” with an area under the curve of 0.73 upon validation. A second panel, created for vedolizumab, included 22 CpG loci and had an AUC accuracy of 0.89. The third panel, specific to ustekinumab, had 68 CpG loci and an AUC accuracy of 0.94.
The markers are largely unique to each agent. Only two CpG loci overlapped between adalimumab and ustekinumab, Dr. Joustra said.
“Importantly, our model was able to predict response prior to treatment in a completely different set of patients from the Oxford validation cohort with an AUC of 0.75,” Dr. Joustra said.
A secondary analysis revealed no differences in the stability and robustness of the methylation markers between baseline and 28 weeks. This finding implies that the biomarkers are stable during the induction and maintenance phases of treatment.
“Of course, we need to clinically validate our findings in a clinical trial, which is ongoing,” Dr. Joustra said. This work will continue in the EPIC-CD study, as well as in the OMICROHN clinical trial.
Promising start
“These are really interesting findings that address an area of importance in treating patients with Crohn’s disease,” said ECCO session comoderator Tim Raine, PhD, who was not affiliated with the research.
“The team found a signature that appears to provide helpful prediction of response to specific treatments. Importantly, this signature appeared to be stable over time, to be specific to individual drugs, and could be validated in an external cohort of patients,” added Dr. Raine, consultant gastroenterologist at Cambridge (England) University Hospitals NHS Trust.
Although the technologies used in EPIC-CD are not yet routinely available in clinical practice, “the methodologies are well established, and with appropriate development in a validated laboratory, as well as further validation work, could form a useful test for gastroenterologists treating patients with Crohn’s disease,” Dr. Raine said.
The study was independently supported. Dr. Joustra and Dr. Raine reported no relevant financial relationships.

COVID emergency orders ending: What’s next?
It’s the end of an era.
The orders spanned two presidencies. The Trump administration’s Health and Human Services Secretary Alex Azar issued a public health emergency in January 2020. Then-President Donald Trump declared the COVID-19 pandemic a national emergency 2 months later. Both emergency declarations – which remained in effect under President Joe Biden – are set to expire May 11.
Read on for an overview of how the end of the public health emergency will trigger multiple federal policy changes.
Changes that affect everyone
- There will be cost-sharing changes for COVID-19 vaccines, testing, and certain treatments. One hundred–percent coverage for COVID testing, including free at-home tests, will expire May 11.
- Telemedicine cannot be used to prescribe controlled substances after May 11, 2023.
- Enhanced federal funding will be phased down through Dec. 31, 2023. This extends the time states must receive federally matched funds for COVID-related services and products, through the Consolidated Appropriations Act of 2023. Otherwise, this would have expired June 30, 2023.
- Emergency use authorizations for COVID-19 treatments and vaccinations will not be affected and/or end on May 11.
Changes that affect people with private health insurance
- Many will likely see higher costs for COVID-19 tests, as free testing expires and cost-sharing begins in the coming months.
- COVID-19 vaccinations and boosters will continue to be covered until the federal government’s vaccination supply is depleted. If that happens, you will need an in-network provider.
- You will still have access to COVID-19 treatments – but that could change when the federal supply dwindles.
Changes that affect Medicare recipients
- Medicare telehealth flexibilities will be extended through Dec. 31, 2024, regardless of public health emergency status. This means people can access telehealth services from anywhere, not just rural areas; can use a smartphone for telehealth; and can access telehealth in their homes.
- Medicare cost-sharing for testing and treatments will expire May 11, except for oral antivirals.
Changes that affect Medicaid/CHIP recipients
- Medicaid and Children’s Health Insurance Program (CHIP) recipients will continue to receive approved vaccinations free of charge, but testing and treatment without cost-sharing will expire during the third quarter of 2024.
- The Medicaid continuous enrollment provision will be separated from the public health emergency, and continuous enrollment will end March 31, 2023.
Changes that affect uninsured people
- The uninsured will no longer have access to 100% coverage for these products and services (free COVID-19 treatments, vaccines, and testing).
Changes that affect health care providers
- There will be changes to how much providers get paid for diagnosing people with COVID-19, ending the enhanced Inpatient Prospective Payment System reimbursement rate, as of May 11, 2023.
- Health Insurance Portability and Accountability Act (HIPAA) potential penalty waivers will end. This allows providers to communicate with patients through telehealth on a smartphone, for example, without violating privacy laws and incurring penalties.
What the experts are saying
This news organization asked several health experts for their thoughts on ending the emergency health declarations for COVID, and what effects this could have. Many expressed concerns about the timing of the ending, saying that the move could limit access to COVID-related treatments. Others said the move was inevitable but raised concerns about federal guidance related to the decision.
Question: Do you agree with the timing of the end to the emergency order?
Answer: Robert Atmar, MD, professor of infectious diseases at Baylor College of Medicine in Houston: “A lead time to prepare and anticipate these consequences may ease the transition, compared to an abrupt declaration that ends the declaration.”
Answer: Georges C. Benjamin, MD, executive director of the American Public Health Association: “I think it’s time to do so. It has to be done in a great, thoughtful, and organized way because we’ve attached so many different things to this public health emergency. It’s going to take time for the system to adapt. [Centers for Disease Control and Prevention] data collection most likely will continue. People are used to reporting now. The CDC needs to give guidance to the states so that we’re clear about what we’re reporting, what we’re not. If we did that abruptly, it would just be a mess.”
Answer: Bruce Farber, MD, chief public health and epidemiology officer at Northwell Health in Manhasset, N.Y.: “I would have hoped to see it delayed.”
Answer: Steven Newmark, JD, chief legal officer and director of policy at the Global Healthy Living Foundation: “While we understand that an emergency cannot last forever, we hope that expanded services such as free vaccination, promotion of widespread vaccination, increased use of pharmacists to administer vaccines, telehealth availability and reimbursement, flexibility in work-from-home opportunities, and more continues. Access to equitable health care should never backtrack or be reduced.”
Q: What will the end of free COVID vaccinations and free testing mean?
A: Dr. Farber: “There will likely be a decrease in vaccinations and testing. The vaccination rates are very low to begin with, and this will likely lower it further.”
A: Dr. Atmar: “I think it will mean that fewer people will get tested and vaccinated,” which “could lead to increased transmission, although wastewater testing suggests that there is a lot of unrecognized infection already occurring.”
A: Dr. Benjamin: “That is a big concern. It means that for people, particularly for people who are uninsured and underinsured, we’ve got to make sure they have access to those. There’s a lot of discussion and debate about what the cost of those tests and vaccines will be, and it looks like the companies are going to impose very steep, increasing costs.”
Q: How will this affect higher-risk populations, like people with weakened immune systems?
A: Dr. Farber: “Without monoclonals [drugs to treat COVID] and free Paxlovid,” people with weakened immune systems “may be undertreated.”
A: Dr. Atmar: “The implications of ongoing widespread virus transmission are that immunocompromised individuals may be more likely to be exposed and infected and to suffer the consequences of such infection, including severe illness. However, to a certain degree, this may already be happening. We are still seeing about 500 deaths/day, primarily in persons at highest risk of severe disease.”
A: Dr. Benjamin: “People who have good insurance, can afford to get immunized, and have good relations with practitioners probably will continue to be covered. But lower-income individuals and people who really can’t afford to get tested or get immunized would likely become underimmunized and more infected.
“So even though the federal emergency declaration will go away, I’m hoping that the federal government will continue to encourage all of us to emphasize those populations at the highest risk – those with chronic disease and those who are immunocompromised.”
A: Mr. Newmark: “People who are immunocompromised by their chronic illness or the medicines they take to treat acute or chronic conditions remain at higher risk for COVID-19 and its serious complications. The administration needs to support continued development of effective treatments and updated vaccines to protect the individual and public health. We’re also concerned that increased health care services - such as vaccination or telehealth – may fall back to prepandemic levels while the burden of protection, such as masking, may fall to chronic disease patients alone, which adds to the burden of living with disease.”
Q: What effect will ending Medicaid expansion money have?
A: Dr. Benjamin: Anywhere from 16 to 20 million people are going to lose in coverage. I’m hoping that states will look at their experience over these last 2 years or so and come to the decision that there were improvements in healthier populations.
Q: Will this have any effect on how the public perceives the pandemic?
A: Dr. Farber: “It is likely to give the impression that COVID is gone, which clearly is not the case.”
A: Dr. Benjamin: “It’ll be another argument by some that the pandemic is over. People should think about this as kind of like a hurricane. A hurricane comes through and tragically tears up communities, and we have an emergency during that time. But then we have to go through a period of recovery. I’m hoping people will realize that even though the public health emergencies have gone away, that we still need to go through a period of transition ... and that means that they still need to protect themselves, get vaccinated, and wear a mask when appropriate.”
A: Dr. Atmar: “There needs to be messaging that while we are transitioning away from emergency management of COVID-19, it is still a significant public health concern.”

It’s the end of an era.
The orders spanned two presidencies. The Trump administration’s Health and Human Services Secretary Alex Azar issued a public health emergency in January 2020. Then-President Donald Trump declared the COVID-19 pandemic a national emergency 2 months later. Both emergency declarations – which remained in effect under President Joe Biden – are set to expire May 11.
Read on for an overview of how the end of the public health emergency will trigger multiple federal policy changes.
Changes that affect everyone
- There will be cost-sharing changes for COVID-19 vaccines, testing, and certain treatments. One hundred–percent coverage for COVID testing, including free at-home tests, will expire May 11.
- Telemedicine cannot be used to prescribe controlled substances after May 11, 2023.
- Enhanced federal funding will be phased down through Dec. 31, 2023. This extends the time states must receive federally matched funds for COVID-related services and products, through the Consolidated Appropriations Act of 2023. Otherwise, this would have expired June 30, 2023.
- Emergency use authorizations for COVID-19 treatments and vaccinations will not be affected and/or end on May 11.

Long COVID affecting more than one-third of college students, faculty
With a median age of 23 years, the study is unique for evaluating mostly healthy, young adults and for its rare look at long COVID in a university community.
The more symptoms during a bout with COVID, the greater the risk for long COVID, the researchers found. That lines up with previous studies. Also, the more vaccinations and booster shots against SARS-CoV-2, the virus that causes COVID, the lower the long COVID risk.
Women were more likely than men to be affected. Current or prior smoking, seeking medical care for COVID, and receiving antibody treatment also were linked to higher chances for developing long COVID.
Lead author Megan Landry, DrPH, MPH, and colleagues were already assessing students, staff, and faculty at George Washington University, Washington, who tested positive for COVID. Then they started seeing symptoms that lasted 28 days or more after their 10-day isolation period.
“We were starting to recognize that individuals ... were still having symptoms longer than the typical isolation period,” said Dr. Landry. So they developed a questionnaire to figure out the how long these symptoms last and how many people are affected by them.
The list of potential symptoms was long and included trouble thinking, fatigue, loss of smell or taste, shortness of breath, and more.
The study was published online in Emerging Infectious Diseases. Results are based on records and responses from 1,388 students, faculty, and staff from July 2021 to March 2022.
People had a median of four long COVID symptoms, about 63% were women, and 56% were non-Hispanic White. About three-quarters were students and the remainder were faculty and staff.
The finding that 36% of people with a history of COVID reported long COVID symptoms did not surprise Dr. Landry.
“Based on the literature that’s currently out there, it ranges from a 10% to an 80% prevalence of long COVID,” she said. “We kind of figured that we would fall somewhere in there.”
In contrast, that figure seemed high to Eric Topol, MD.
“That’s really high,” said Dr. Topol, founder and director of the Scripps Research Translational Institute in La Jolla, Calif. He added most studies estimate that about 10% of people with a history of acute infection develop long COVID.
Even at 10%, which could be an underestimate, that’s a lot of affected people globally.
“At least 65 million individuals around the world have long COVID, based on a conservative estimated incidence of 10% of infected people and more than 651 million documented COVID-19 cases worldwide; the number is likely much higher due to many undocumented cases,” Dr. Topol and colleagues wrote in a long COVID review article published in Nature Reviews Microbiology.
About 30% of study participants were fully vaccinated with an initial vaccine series, 42% had received a booster dose, and 29% were not fully vaccinated at the time of their first positive test for COVID. Those who were not fully vaccinated were significantly more likely to report symptoms of long COVID.
“I know a lot of people wish they could put COVID on the back burner or brush it under the rug, but COVID is still a real thing. We need to continue supporting vaccines and boosters and make sure people are up to date. Not only for COVID, but for flu as well,” Dr. Topol said
Research continues
“Long COVID is still evolving and we continue to learn more about it every day,” Landry said. “It’s just so new and there are still a lot of unknowns. That’s why it’s important to get this information out.”
People with long COVID often have a hard time with occupational, educational, social, or personal activities, compared with before COVID, with effects that can last for more than 6 months, the authors noted.
“I think across the board, universities in general need to consider the possibility of folks on their campuses are having symptoms of long COVID,” Dr. Landry said.
Moving forward, Dr. Landry and colleagues would like to continue investigating long COVID. For example, in the current study, they did not ask about severity of symptoms or how the symptoms affected daily functioning.
“I would like to continue this and dive deeper into how disruptive their symptoms of long COVID are to their everyday studying, teaching, or their activities to keeping a university running,” Dr. Landry said.

“At least 65 million individuals around the world have long COVID, based on a conservative estimated incidence of 10% of infected people and more than 651 million documented COVID-19 cases worldwide; the number is likely much higher due to many undocumented cases,” Dr. Topol and colleagues wrote in a long COVID review article published in Nature Reviews Microbiology.
About 30% of study participants were fully vaccinated with an initial vaccine series, 42% had received a booster dose, and 29% were not fully vaccinated at the time of their first positive test for COVID. Those who were not fully vaccinated were significantly more likely to report symptoms of long COVID.
“I know a lot of people wish they could put COVID on the back burner or brush it under the rug, but COVID is still a real thing. We need to continue supporting vaccines and boosters and make sure people are up to date. Not only for COVID, but for flu as well,” Dr. Topol said
Research continues
“Long COVID is still evolving and we continue to learn more about it every day,” Landry said. “It’s just so new and there are still a lot of unknowns. That’s why it’s important to get this information out.”
People with long COVID often have a hard time with occupational, educational, social, or personal activities, compared with before COVID, with effects that can last for more than 6 months, the authors noted.
“I think across the board, universities in general need to consider the possibility of folks on their campuses are having symptoms of long COVID,” Dr. Landry said.
Moving forward, Dr. Landry and colleagues would like to continue investigating long COVID. For example, in the current study, they did not ask about severity of symptoms or how the symptoms affected daily functioning.
“I would like to continue this and dive deeper into how disruptive their symptoms of long COVID are to their everyday studying, teaching, or their activities to keeping a university running,” Dr. Landry said.

Rise of ‘alarming’ subvariants of COVID ‘worrisome’ for winter
It’s a story perhaps more appropriate for Halloween than for the festive holiday season, given its scary implications.
Not too dire so far, until the researchers’ other findings are considered.
The BQ.1, BQ1.1, XBB, and XBB.1 subvariants are the most resistant to neutralizing antibodies, researcher Qian Wang, PhD, and colleagues wrote in a study published online in the journal Cell. This means people have no or “markedly reduced” protection against infection from these four strains, even if they’ve already had COVID-19 or are vaccinated and boosted multiple times, including with a bivalent vaccine.
On top of that, all available monoclonal antibody treatments are mostly or completely ineffective against these subvariants.
What does that mean for the immediate future? The findings are definitely “worrisome,” said Eric Topol, MD, founder and director of the Scripps Translational Research Institute in La Jolla, Calif.
But evidence from other countries, specifically Singapore and France, show that at least two of these variants turned out not to be as damaging as expected, likely because of high numbers of people vaccinated or who survived previous infections, he said.
Still, there is little to celebrate in the new findings, except that COVID-19 vaccinations and prior infections can still reduce the risk for serious outcomes such as hospitalization and death, the researchers wrote.
In fact, Centers for Disease Control and Prevention data released on Dec. 16 shows that people who have received four shots of the original COVID-19 vaccines as well as the bivalent booster were 57% less likely to visit an urgent care clinic or emergency room, regardless of age.
It comes at a time when BQ.1 and BQ.1.1 account for about 70% of the circulating variants, data show. In addition, hospitalizations are up 18% over the past 2 weeks and COVID-19 deaths are up 50% nationwide, The New York Times reported.
Globally, in many places, an “immunity wall” that has been built, Dr. Topol said. That may not be the case in the United States.
“The problem in the United States, making it harder to predict, is that we have a very low rate of recent boosters, in the past 6 months, especially in seniors,” he said. For example, only 36% of Americans aged 65 years and older, the group with highest risk, have received an updated bivalent booster.
An evolving virus
The subvariants are successfully replacing BA.5, which reigned as one of the most common Omicron variants over the past year. The latest CDC data show that BA.5 now accounts for only about 10% of the circulating virus. The researchers wrote: “This rapid replacement of virus strains is raising the specter of yet another wave of infections in the coming months.”
BQ.1 and BQ.1.1 evolved directly from BA.5 – adding more and some novel mutations to the SARS-CoV-2 virus. XBB and XBB.1 are the “offspring” of a combination of two other strains, known as BJ.1 and BA.2.75.
The story sounds familiar to the researchers. “The rapid rise of these subvariants and their extensive array of spike mutations are reminiscent of the appearance of the first Omicron variant last year, thus raising concerns that they may further compromise the efficacy of current COVID-19 vaccines and monoclonal antibody therapeutics,” they wrote. “We now report findings that indicate that such concerns are, sadly, justified, especially so for the XBB and XBB.1 subvariants.”
To figure out how effective existing antibodies could be against these newer subvariants, Dr. Wang and colleagues used blood samples from five groups of people. They tested serum from people who had three doses of the original COVID-19 vaccine, four doses of the original vaccine, those who received a bivalent booster, people who experienced a breakthrough infection with the BA.2 Omicron variant, and those who had a breakthrough with a BA.4 or BA.5 variant.
Adding the new subvariants to these serum samples revealed that the existing antibodies in the blood were ineffective at wiping out or neutralizing BQ.1, BQ.1.1, XBB, and XBB.1.
The BQ.1 subvariant was six times more resistant to antibodies than BA.5, its parent strain, and XBB.1 was 63 times more resistant compared with its predecessor, BA.2.
This shift in the ability of vaccines to stop the subvariants “is particularly concerning,” the researchers wrote.
Wiping out treatments too
Dr. Wang and colleagues also tested how well a panel of 23 different monoclonal antibody drugs might work against the four subvariants. The therapies all worked well against the original Omicron variant and included some approved for use through the Food and Drug Administration emergency use authorization (EUA) program at the time of the study.
They found that 19 of these 23 monoclonal antibodies lost effectiveness “greatly or completely” against XBB and XBB.1, for example.
This is not the first time that monoclonal antibody therapies have gone from effective to ineffective. Previous variants have come out that no longer responded to treatment with bamlanivimab, etesevimab, imdevimab, casirivimab, tixagevimab, cilgavimab, and sotrovimab. Bebtelovimab now joins this list and is no longer available from Eli Lilly under EUA because of this lack of effectiveness.
The lack of an effective monoclonal antibody treatment “poses a serious problem for millions of immunocompromised individuals who do not respond robustly to COVID-19 vaccines,” the researchers wrote, adding that “the urgent need to develop active monoclonal antibodies for clinical use is obvious.”
A limitation of the study is that the work is done in blood samples. The effectiveness of COVID-19 vaccination against the BQ and XBB subvariants should be evaluated in people in clinical studies, the authors noted.
Also, the current study looked at how well antibodies could neutralize the viral strains, but future research, they added, should look at how well “cellular immunity” or other aspects of the immune system might protect people.
Going forward, the challenge remains to develop vaccines and treatments that offer broad protection as the coronavirus continues to evolve.
In an alarming ending, the researchers wrote: “We have collectively chased after SARS-CoV-2 variants for over 2 years, and yet, the virus continues to evolve and evade.”
