TOPLINE:

A high-fiber diet affects small intestine metabolism, spurring release of the appetite-suppressing gut hormone peptide tyrosine tyrosine (PYY) more than a low-fiber diet, and it does so regardless of the food’s structure, new research revealed.

METHODOLOGY:

• Researchers investigated how low- and high-fiber diets affect the release of the gut hormones PYY and glucagon-like peptide 1 (GLP-1).
• They randomly assigned 10 healthy volunteers to 4 days on one of three diets: High-fiber intact foods, such as peas and carrots; high-fiber foods with disrupted structures (same high-fiber foods, but mashed or blended); or low-fiber processed foods. Volunteers then participated in the remaining two diets in a randomized order, with a washout period of at least a week in which they reverted to their normal diet between each session.
• The diets were energy- and macronutrient-matched, but only the two high-fiber diets were fiber-matched at 46.3-46.7 grams daily, whereas the low-fiber diet contained 12.6 grams of daily fiber.
• The researchers used nasoenteric tubes to sample chyme from the participants’ distal ileum lumina in a morning fasted state and every 60 minutes for 480 minutes postprandially on days 3 and 4 and confirmed their findings using ileal organoids. Participants reported their postprandial hunger using a visual analog scale.

TAKEAWAY:

• Both high-fiber diets increased PYY release — but not GLP-1 release — compared with a low-fiber diet during the 0-240-minute postprandial period, when the food was mainly in the small intestine.
• At 120 minutes, both high-fiber diets increased PYY compared with the low-fiber diet, a finding that counteracted the researchers’ hypothesis that intact food structures would stimulate PYY to a larger extent than disrupted food structures. Additionally, participants reported less hunger at 120 minutes with the high-fiber diets, compared with the low-fiber diet.
• High-fiber diets also increased ileal stachyose, and the disrupted high-fiber diet increased certain ileal amino acids.
• Treating the ileal organoids with ileal fluids or an amino acid and stachyose mixture stimulated PYY expression similarly to blood PYY expression, confirming the role of ileal metabolites in the release of PYY.

IN PRACTICE:

“High-fiber diets, regardless of their food structure, increased PYY release through alterations in the ileal metabolic profile,” the authors wrote. “Ileal molecules, which are shaped by dietary intake, were shown to play a role in PYY release, which could be used to design diets to promote satiety.”

The study, led by Aygul Dagbasi, PhD, Imperial College London, England, was published online in Science Translational Medicine

LIMITATIONS:

The study had several limitations, including the small number of participants. The crossover design limited the influence of covariates on the study outcomes. Gastric emptying and gut transit rates differed widely; therefore, food that may have reached and affected the ileum prior to the first postprandial sample point at 60 minutes was not captured. The authors had access to a limited number of organoids, which restricted the number of experiments they could do. Although organoids are useful tools in vitro, they have limitations, the researchers noted.

The research was funded by the Biotechnology and Biological Sciences Research Council (BBSRC), Nestle Research, and Sosei Heptares. The Section for Nutrition at Imperial College London is funded by grants from the UK Medical Research Council, BBSRC, National Institute for Health and Care Research, and UKRI Innovate UK and is supported by the National Institute for Health and Care Research Imperial Biomedical Research Centre Funding Scheme.

An estimated two million people in England and Scotland were experiencing symptoms of long COVID as of March 2024, according to the Office for National Statistics. Of these, 1.5 million said the condition was adversely affecting their day-to-day activities.

As more research emerges about long COVID, some experts are noticing that its trigger factors, symptoms, and causative mechanisms overlap with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

ME/CFS is characterized by severe fatigue that does not improve with rest, in addition to pain and cognitive problems. One in four patients are bed- or house-bound with severe forms of the condition, sometimes experiencing atypical seizures, and speech and swallowing difficulties.

Despite affecting around 250,000 people in the UK and around 2 million people in the European Union (EU), it is a relatively poorly funded disease research area. Increased research into long COVID is thus providing a much-needed boost to ME/CFS research.

“What we already know about the possible causation of ME/CFS is helping research into the causes of long COVID. At the same time, research into long COVID is opening up new avenues of research that may also be relevant to ME/CFS. It is becoming a two-way process,” Dr. Charles Shepherd, honorary medical adviser to the UK-based ME Association, told this news organization.

While funding remains an issue, promising research is currently underway in the UK to improve diagnosis, treatment, and understanding of the pathology of ME/CFS.
 

Viral Reactivation

Dr. David Newton is research director at ME Research UK. “Viral infection is commonly reported as a trigger for [ME/CFS, meaning that the disease] may be caused by reactivation of latent viruses, including human herpes viruses and enteroviruses,” he said.

Herpes viruses can lie dormant in their host’s immune system for long periods of time. They can be reactivated by factors including infections, stress, and a weakened immune system, and may cause temporary symptoms or persistent disease.

A 2021 pilot study found that people with ME/CFS have a higher concentration of human herpesvirus 6B (HHV-6B) DNA in their saliva, and that concentration correlates with symptom severity. HHV-6B is a common virus typically contracted during infancy and childhood.

A continuation of this research is now underway at Brunel University to improve understanding of HHV-6B’s role in the onset and progression of ME/CFS, and to support the development of diagnostic and prognostic markers, as well as therapeutics such as antiviral therapies.
 

Mitochondrial Dysfunction

Dr. Shepherd explained that there is now sound evidence demonstrating that biochemical abnormalities in ME/CFS affect how mitochondria produce energy after physical exertion. Research is thus underway to see if treating mitochondrial dysfunction improves ME/CFS symptoms.

A phase 2a placebo-controlled clinical trial from 2023 found that AXA1125, a drug that works by modulating energy metabolism, significantly improved symptoms of fatigue in patients with fatigue-dominant long COVID, although it did not improve mitochondrial respiration.

“[The findings suggest] that improving mitochondrial health may be one way to restore normal functioning among people with long COVID, and by extension CFS,” study author Betty Raman, associate professor of cardiovascular medicine at the University of Oxford, told this news organization. She noted, however, that plans for a phase III trial have stalled due to insufficient funding.

Meanwhile, researchers from the Quadram Institute in Norwich and the University of East Anglia are conducting a pilot study to see if red light therapy can relieve symptoms of ME/CFS. Red light can be absorbed by mitochondria and is used to boost energy production. The trial will monitor patients remotely from their homes and will assess cognitive function and physical activity levels.
 

Gut Dysbiosis

Many studies have found that people with ME/CFS have altered gut microbiota, which suggests that changes in gut bacteria may contribute to the condition. Researchers at the Quadram Institute will thus conduct a clinical trial called RESTORE-ME to see whether fecal microbiota transplants (FMT) can treat the condition.

Rik Haagmans is a research scientist and PhD candidate at the Quadram Institute. He told this news organization: “Our FMT studies, if effective, could provide a longer lasting or even permanent relief of ME/CFS, as restoring the gut microbial composition wouldn’t require continuous medication,” he said.
 

Biobank and Biomarkers

Europe’s first ME/CFS-specific biobank is in the UK and is called UKMEB. It now has more than 30,000 blood samples from patients with ME/CFS, multiple sclerosis, and healthy controls. Uniquely, it includes samples from people with ME/CFS who are house- and bed-bound. Caroline Kingdon, RN, MSc, a research fellow and biobank lead at the London School of Hygiene and Tropical Medicine, told this news organization that samples and data from the UKMEB have been provided to research groups all over the world and have contributed to widely cited literature.

One group making use of these samples is led by Fatima Labeed, PhD, senior lecturer in human biology at the University of Surrey. Dr. Labeed and her team are developing a diagnostic test for ME/CFS based on electrical properties in white blood cells.

“To date, studies of ME/CFS have focused on the biochemical behavior of cells: the amount and type of proteins that cells use. We have taken a different approach, studying the electrical properties,” she explained to this news organization.

Her research builds on initial observations from 2019 that found differences in the electrical impedance of white blood cells between people with ME/CFS and controls. While the biological implications remain unknown, the findings may represent a biomarker for the condition.

Using blood samples from the UKMEB, the researchers are now investigating this potential biomarker with improved techniques and a larger patient cohort, including those with mild/moderate and severe forms of ME/CFS. So far, they have received more than 100 blood samples and have analyzed the electrical properties of 42.

“Based on the results we have so far, we are very close to having a biomarker for diagnosis. Our results so far show a high degree of accuracy and are able to distinguish between ME/CFS and other diseases,” said Dr. Labeed.
 

Genetic Test

Another promising avenue for diagnostics comes from a research team at the University of Edinburgh led by Professor Chris Ponting at the university’s Institute of Genetics and Cancer. They are currently working on DecodeMe, a large genetic study of ME using data from more than 26,000 people.

“We are studying blood-based biomarkers that distinguish people with ME from population controls. We’ve found a large number — including some found previously in other studies — and are writing these results up for publication,” said Ponting. The results should be published in early 2025.
 

The Future

While research into ME/CFS has picked up pace in recent years, funding remains a key bottleneck.

“Over the last 10 years, only £8.05m has been spent on ME research,” Sonya Chowdhury, chief executive of UK charity Action for ME told this news organization. She believes this amount is not equitably comparable to research funding allocated to other diseases.

In 2022, the UK government announced its intention to develop a cross-government interim delivery plan on ME/CFS for England, however publication of the final plan has been delayed numerous times.

Dr. Shepherd agreed that increased funding is crucial for progress to be made. He said the biggest help to ME/CFS research would be to end the disparity in government research funding for the disease, and match what is given for many other disabling long-term conditions.

“It’s not fair to continue to rely on the charity sector to fund almost all of the biomedical research into ME/CFS here in the UK,” he said.

TOPLINE:

Long-term gender-affirming hormone treatment with testosterone increases the risk for metabolic syndromes in transmasculine individuals, whereas transfeminine individuals receiving estradiol have a lower risk.

METHODOLOGY:

• Many transgender individuals receive exogenous sex hormone therapy to reduce gender dysphoria and improve quality of life. These treatments, however, may influence the development of metabolic syndrome.
• This retrospective, longitudinal cohort study investigated the association between gender-affirming hormone treatment and metabolic syndrome scores in transfeminine and transmasculine individuals compared with cisgender men and women not receiving the treatment.
• Overall, 645 transgender participants (mean age at index date, 41.3 years; 494 transfeminine and 151 transmasculine) were matched with 645 cisgender participants (280 women and 365 men) from the Veterans Health Administration.
• Metabolic syndrome scores were calculated based on blood pressure; body mass index (BMI); and levels of high-density lipoprotein (HDL) cholesterol, triglycerides, and blood glucose.
• Changes in metabolic syndrome scores before and after hormonal transition were compared among transgender and cisgender individuals for the corresponding dates.

TAKEAWAY:

• After hormonal transition, all measured metabolic syndrome components significantly worsened in the transmasculine group (P < .05 for all).
• In contrast, the systolic blood pressure and triglyceride levels decreased, HDL cholesterol levels increased, and BMI showed no significant change in the transfeminine group after hormonal transition.
• The increase in metabolic syndrome scores after vs before the date of hormonal transition was the highest for transmasculine individuals (298.0%; P < .001), followed by cisgender women (108.3%; P < .001), cisgender men (49.3%; P = .02), and transfeminine individuals (3.0%; P = .77).

IN PRACTICE:

“This is relevant for the management of metabolic syndrome risk factors in cisgender and transgender individuals and to potentially predict the risk of atherosclerotic cardiovascular disease, type 2 diabetes, systolic hypertension, insulin resistance, and nonalcoholic fatty liver disease,” the authors wrote.

Patients starting first-line endocrine and CDK4/6 inhibition for advanced breast cancer show minimal additional cognitive decline beyond what they had already experienced from their neoadjuvant and adjuvant treatments, according to new results of the SONIA trial.

“Patients who are diagnosed with advanced breast cancer and start their first-line treatment already show cognitive impairments due to their previous treatments. And luckily, our results show that during first-line treatment for advanced breast cancer with endocrine therapy, with or without a CDK4/6 inhibitor, further cognitive decline is minimal,” lead investigator Maryse Luijendijk, said during her presentation at the annual meeting of the American Society of Clinical Oncology (ASCO).

“It is well known that cancer patients can experience cognitive problems, such as memory loss, problems with concentration or with planning, during or following their treatment,” explained Ms. Luijendijk, a PhD candidate in the department of Psychosocial Research and Epidemiology at the Netherlands Cancer Institute, in Amsterdam. “Much is known about the effects of chemotherapy or irradiation to the brain, but evidence into endocrine therapy is scarce, which is surprising because cognitive effects are biologically plausible.

“We know that estrogen plays an important role in neuronal functioning and that certain types of endocrine therapies are able to cross the blood-brain barrier, where they may interact with estrogen receptors distributed widely throughout the brain … We know that CDK4/6 inhibitors may either negatively affect cognitive function by increased fatigue due to cytokine release or by interrupting the cell cycle of healthy cells, or positively, as they have been associated with reduced inflammation and remyelination.”

Initial results of the SONIA trial, reported at ASCO last year, examined overall and progression-free survival in patients with HR-positive, HER2-negative metastatic breast cancer and no prior treatment for advanced disease. Findings for those who were randomized to treatment with nonsteroidal aromatase inhibition either with or without the addition of CDK4/6 inhibitors showed no between-group differences, explained Ms. Luijendijk.

The new results, described as being from the SONIA-EfFECT (Evaluation of cognitive functioning in patients with metastatic breast cancer treated with endocrine or combined therapy) trial, were based on the authors investigating cognitive functioning in the same cohort used in the SONIA trial plus a control group.

In SONIA-EfFECT, patients who participated in SONIA were asked to identify a female relative or friend without cancer to serve as a cancer-free control. Members of the 130-patient control group were matched for age, education, and computer use.

Participants in the SONIA trial and control group were asked to complete the Amsterdam Cognition Scan, an online neuropsychological test battery at baseline and again after 9 months of treatment. Of those patients from SONIA, 130 had received first-line treatment with aromatase inhibitors with CDK4/6 inhibition (Arm A) and 130 had received aromatase inhibitors without CDK4/6 inhibition (Arm B).

Baseline assessments for SONIA-EfFECT were completed for 260 patients from SONIA and the full 130-person control group. Follow-up assessments were completed for 119 members of the control group and 199 patients from the original SONIA trial (108 from Arm A, and 91 from Arm B). Patients from SONIA who switched to second-line treatment within 9 months were not retested.

Patients in both SONIA arms performed significantly worse than the controls on the domains of verbal memory, working memory, processing speed, executive function, and motor function. In both patient arms and the controls, standardized regression-based change scores showed limited decline in cognitive function over the 9-month interval. Minimal differences in cognitive change were observed between the patients treated with and without CDK4/6 inhibitors, and between patients and the controls, according to the abstract for SONIA-EfFECT, published in the program for the annual meeting of ASCO.

“At baseline, patients show worse cognitive function across all domains compared to the controls. And as expected, there were no differences between the two treatment arms,” Ms. Luijendijk explained. After 9 months of treatment, the testing showed limited further decline among patients, “and even some improvement on some tests,” with minimal differences between treatment arms “implying that cognitive function does not need to be an aspect when deciding on treatment.”

Ms. Luijendijk reported no relevant disclosures.

HELSINKI, FINLAND — A new gene for early-onset Parkinson’s disease has been identified, a discovery that experts believe will have important clinical implications in the not-too-distant future.

A variant in PMSF1, a proteasome regulator, was identified in 15 families from 13 countries around the world, with 22 affected individuals.

“These families were ethnically diverse, and in all of them, the variant in PMSF1 correlated with the neurologic phenotype. We know this is very clear cut — the genotype/phenotype correlation — with the patients carrying the missense mutation having ‘mild’ symptoms, while those with the progressive loss-of-function variant had the most severe phenotype,” she noted. 

“Our findings unequivocally link defective PSMF1 to early-onset PD and neurodegeneration and suggest mitochondrial dysfunction as a mechanistic contributor,” study investigator Francesca Magrinelli, MD, PhD, of University College London (UCL) Queen Square Institute of Neurology, UCL, London, told delegates at the 2024 Congress of the European Academy of Neurology.
 

Managing Patient Expectations

Those “mildly” affected had an early-onset Parkinson’s disease starting between the second and fifth decade of life with pyramidal tract signs, dysphasia, psychiatric comorbidity, and early levodopa-induced dyskinesia. 

In those with the intermediate type, Parkinson’s disease symptoms start in childhood and include, among other things, global hypokinesia, developmental delay, cerebellar signs, and in some, associated epilepsy.

In most cases, there was evidence on brain MRI of a hypoplasia of the corpus callosum, Dr. Magrinelli said. In the most severely affected individuals, there was perinatal lethality with neurologic manifestations.

While it may seem that the genetics of Parkinson’s disease is an academic exercise for the most part, it won’t be too much longer before it yields practical information that will inform how patients are treated, said Parkinson’s disease expert Christine Klein, MD, of the Institute of Neurogenetics and Department of Neurology, University of Lübeck, Helsinki, Finland. 

The genetics of Parkinson’s disease are complicated, even within a single family. So, it’s very important to assess the pathogenicity of different variants, Dr. Klein noted. 

“I am sure that you have all had a Parkinson’s disease [gene] panel back, and it says, ‘variant of uncertain significance.’ This is the worst thing that can happen. The lab does not know what it means. You don’t know what it means, and you don’t know what to tell the patient. So how do you get around this?”

Dr. Klein said that before conducting any genetic testing, clinicians should inform the patient that they may have a genetic variant of uncertain significance. It doesn’t solve the problem, but it does help physicians manage patient expectations. 
 

Clinical Relevance on the Way?

While it may seem that all of the identified variants that predict Parkinson’s disease which, in addition to PSMF1, include the well-established LRRK2 and GBA1, may look the same, this is not true when patient history is taken into account, said Dr. Klein.

For example, age-of-onset of Parkinson’s disease can differ between identified variants, and this has led to “a paradigm change” whereby a purely genetic finding is called a disease. 

This first occurred in Huntington’s disease, when researchers gave individuals at high genetic risk of developing the illness, but who currently had no clinical symptoms, the label of “Stage Zero disease.”

This is important to note “because if we get to the stage of having drugs that can slow down, or even prevent, progression to Parkinson’s disease, then it will be key to have patients we know are going to develop it to participate in clinical trials for such agents,” said Dr. Klein. 

She cited the example of a family that she recently encountered that had genetic test results that showed variants of unknown significance, so Dr. Klein had the family’s samples sent to a specialized lab in Dundee, Scotland, for further analysis.

“The biochemists found that this variant was indeed pathogenic, and kinase-activating, so this is very helpful and very important because there are now clinical trials in Parkinson’s disease with kinase inhibitors,” she noted. 

“If you think there is something else [over and above the finding of uncertain significance] in your Parkinson’s disease panel, and you are not happy with the genetic report, send it somewhere else,” Dr. Klein advised. 

“We will see a lot more patients with genetic Parkinson’s disease in the future,” she predicted, while citing two recent preliminary clinical trials that have shown some promise in terms of neuroprotection in patients with early Parkinson’s disease.

“It remains to be seen whether there will be light at the end of the tunnel,” she said, but it may soon be possible to find treatments that delay, or even prevent, Parkinson’s disease onset.

She cited the example of a family that she recently encountered that had genetic test results that showed variants of unknown significance, so Dr. Klein had the family’s samples sent to a specialized lab in Dundee, Scotland, for further analysis.

“The biochemists found that this variant was indeed pathogenic, and kinase-activating, so this is very helpful and very important because there are now clinical trials in Parkinson’s disease with kinase inhibitors,” she noted. 

“If you think there is something else [over and above the finding of uncertain significance] in your Parkinson’s disease panel, and you are not happy with the genetic report, send it somewhere else,” Dr. Klein advised. 

“We will see a lot more patients with genetic Parkinson’s disease in the future,” she predicted, while citing two recent preliminary clinical trials that have shown some promise in terms of neuroprotection in patients with early Parkinson’s disease.

“It remains to be seen whether there will be light at the end of the tunnel,” she said, but it may soon be possible to find treatments that delay, or even prevent, Parkinson’s disease onset.

It’s the difference between running a marathon and taking a leisurely stroll. That’s how recent pediatrics resident Joey Whelihan, MD, compared an 11-hour inpatient hospital day with an 8-hour outpatient shift where residents see patients in a clinic.

With inpatient training, “you are lucky if you have time to cook dinner, go to bed, and get ready for the next day,” said Dr. Whelihan, who recently started his adolescent medicine fellowship at Children’s Hospital of Philadelphia after 3 years of residency there. Some residents have call every fourth day during inpatient rotations, working 24-28 hours at a time. They come in one morning and go home the next, he told this news organization.

“Outpatient blocks give you more time to catch your breath and feel somewhat refreshed and ready to take care of patients.”

Longer stretches of inpatient rotations are not sustainable, Dr. Whelihan added, and residents are likely to become exhausted. Fatigue is a leading cause of burnout, a mental, physical, and emotional challenge that residency programs and national medical organizations have been struggling to address.

In recent years, there has been a movement to reduce the maximum consecutive duration of resident duty hours in residency programs across the country. Fueled by resident health and patient safety concerns, the movement is a shift from the previous 24- to 36-hour call duty schedules.
 

Improved Call Systems = Better Residents

The connection between burnout, well-being, and work schedules appears regularly in national program standards. “Residents and faculty members are at risk for burnout and depression,” according to the current Accreditation Council for Graduate Medical Education’s standard residency program requirements.

“Programs, in partnership with their sponsoring institutions, have the same responsibility to address well-being as other aspects of resident competence,” the guidelines state. That charge includes “attention to scheduling, work intensity, and work compression that impacts resident well-being.”

In Medscape’s Residents Lifestyle & Happiness Report 2023, a third of residents surveyed rarely or never paid attention to their well-being, which closely mirrors the 31% who rarely or never had time for a social life. Slightly more residents (37%) said their work-life balance was “somewhat worse” or “much worse” than they expected.

“I think everyone has burnout as a resident, regardless of the type of program they are in,” Dr. Whelihan said. He described the experience as when you lack fulfillment and empathy and feel exhausted, callous, and removed from interactions with colleagues and patients.

The American Medical Association’s recently released report on the state of residency well-being in 2023 also found that about 43% of residents and fellows had at least one symptom of burnout, about a 2% increase from 2022.
 

Efforts to Combat Burnout

One residency program found a way to reduce burnout by changing its block scheduling from 4 inpatient weeks followed by 1 outpatient week (4 + 1) to 4 inpatient call-based weeks and 4 outpatient ambulatory, non-call weeks (4 + 4), according to a survey study published recently in JAMA Network Open. The initiative drew praise from some residents and a med school professor who studies wellness issues.

In the survey of postgraduate year (PGY) 1 and PGY-2 hospitalist and primary care residents from the University of Colorado’s Internal Medicine Residency Program, Aurora, between June 2019 and June 2021, the schedule change resulted in improved burnout scores and self-reported professional, educational, and health benefits.

As part of the survey, residents rated symptoms on a 7-point scale on the basis of how frequently they experienced emotional exhaustion, depersonalization, and personal accomplishment.

Investigators also used a questionnaire to evaluate how participants perceived the rotation structure with various outcomes, including the ability to acquire clinical skills, access educational and scholarly opportunities, job satisfaction, and health.

The study concluded that the schedule change improved burnout, health, wellness, and professional development without weakening residents perceived clinical skills or standardized exam scores.

Still, the study authors acknowledged that several factors, including the pandemic, may have limited the findings. During that time, the study transitioned from in-person to electronic submissions, resulting in reduced response rates because of changes in staffing needs and fewer research and scholarly activities.

“One of the things we worried about was that the pandemic would make [burnout findings] look worse,” said lead author Dan Heppe, MD, a hospitalist and associate director of the CU Internal Medicine Residency Program. “Anecdotally, residents may have had more support in our program than perhaps some other programs. Though they had long hours with very sick patients, we tried to keep going in a positive direction.”

Dr. Heppe said in an interview that the purpose of the schedule change was to space out more intense rotations and build in more time for research, leadership, teaching, and professional development. He suggested the new schedule could help with other aspects of residents’ careers, exposing them to alternate avenues earlier in their training and in a more structured way.

Like most of the study authors, Dr. Heppe is a graduate of the residency program. He recalled how the program changed from multiple inpatient months in a row with clinic half days during those rotations to a 4 + 1 schedule. But the 1 week between inpatient rotations wasn’t enough time to recover or catch up on clinical work, said Dr. Heppe, who is also an associate professor of medicine at CU.

“It was too erratic,” he said of his former residency schedule. “There was a month of research here or there and clinic and then right back to the ICU for a couple of months without a break, and it was less predictable.”

Dr. Heppe said other residency programs have expressed interest in duplicating CU’s schedule change. He admits it may be difficult because of intensive schedule coordination, and some hospitals may not want to reduce clinical services.

The Yale Internal Medicine Traditional Residency Program also recently ended its 28-hour call, during which residents worked 24 hours with an additional 4 hours to transfer the patient to the incoming team. The move was made in response to residents’ requests, saying that the grueling call rotation’s time had come. The reaction has been overwhelmingly positive.

Proponents of alternate scheduling blocks [4 + 4 or 6 + 2] say that they improve residents’ educational experience, patient care, and continuity of care, reduce burnout, and guarantee residents time off.
 

Advancing Resident Well-Being

“The premise of looking at scheduling in a more intentional way is a sound one in the process of trying to support and advance resident well-being,” said Mark Greenawald, MD, vice chair of academic affairs, well-being, and professional development for the Virginia Tech Carilion School of Medicine’s Department of Family and Community Medicine in Roanoke.

He said it’s up to residency program directors or graduate medical education departments within a specialty to determine whether such scheduling changes fit their requirements for inpatient and outpatient care and training electives. Requirements may limit some scheduling changes, but within the specialty, there’s some flexibility to be creative with rotations. The CU study considered how to create a residency rhythm without stacking inpatient rotations so there’s recovery time.

“Human beings need a break. If residents work 80 hours continually, they will start to experience greater distress, which for many leads to burnout,” he said

Still, the study includes design flaws because it doesn’t explain how call times and hours differ between inpatient and outpatient rotations. “My own [family medicine] program also does outpatient clinics when we have inpatient service. We have half days in the clinic, which ensures better continuity care with the patient.”

Dr. Greenawald has yet to see much research published about the impact of resident schedule changes. By taking an experimental approach, the CU study showed that their particular change positively affected burnout. If the study leads to improvements in rotation schedules or encourages other programs to experiment with their schedules, it will be a step in the right direction.
 

How Residents Respond

Haidn Foster, MD, a third-year internal medicine resident at Penn State Health Milton S. Hershey Medical Center, Hershey, remembered experiencing burnout as an intern. At that time, he occasionally dealt with poor patient outcomes and sick patients while working long hours with only 1 day off each week. During a particularly challenging rotation, he felt overwhelmed and numb, which was exacerbated if a patient’s condition worsened or they passed away, he said.

His program follows a schedule of 6 weeks of inpatient training and 2 weeks of outpatient rotations (6 + 2). He said that restructuring residents’ schedules may be more effective than commonly used individual wellness modules, referring to the CU study. “The authors tried out a novel systematic way to tackle the epidemic of physician burnout overwhelming people in the medical community.”

Although the study found that schedule changes don’t affect standardized exam scores, Dr. Foster wondered about preceptor ratings, another marker for clinical competency.

He said future studies should attempt to change the structure of medical training delivery by evaluating models that best reduce burnout, are consistent with residents’ career goals, and produce competent physicians. “Burnout plagues our medical system and leads to too many physicians and physicians-in-training leaving the field or taking their lives. I’m not sure this particular mechanism gets us there, but it’s a step, and so that’s very important.”

Like Dr. Foster, Dr. Whelihan follows a 6 + 2 schedule. He said he would have welcomed a schedule that included more outpatient and less inpatient training and can see how changes in scheduling could reduce burnout. “More outpatient time gives you an opportunity to breathe. You get a little more time off working in clinic with less sick people at a slower pace.”

Ally Fuher, MD, said she chose CU’s Internal Medicine Residency Program 4 years ago largely because of its innovative schedule. Now the program’s chief medical resident, she knew the structure would give her more time to pursue other nonclinical interests including research and medical education, meet regularly with mentors, visit family in another state, and attend important life events.

She acknowledged that the alternative would have meant a more irregular schedule with the possibility of working as many as 80 hours a week on back-to-back inpatient rotations with only 1 day off a week, leaving minimal time to plan other activities, let alone rest and recover.

Dr. Fuher said a balanced schedule made her a more well-rounded person excited to engage in her profession. While she hasn’t personally experienced burnout, she realizes a schedule change may not completely solve the issue for others. However, it shows what progress programs can make when they create systemic structural change.

During a lecture at the 2024 International Congress on Obesity in São Paulo, Brazil, Dr. Carel Le Roux, a South African researcher, reflected on the Stratification of Obesity Phenotypes to Optimize Future Therapy (SOPHIA) project. The effort, of which Dr. Le Roux is a leader, involves using federated data and reframing obesity as a set of diseases, each with its own peculiarities and treatment needs.

A collaborative research initiative led by the European Union, the SOPHIA project is a public-private partnership that brings together healthcare professionals, universities, industry leaders, and patient organizations to rethink how we understand and treat obesity, considering factors beyond body mass index (BMI).

“We need to ask ourselves, ‘Is obesity a disease? Or, in fact, does ‘obesity’ refer to multiple diseases that lead to excess adipose tissue?’ ” Dr. Le Roux asked at the beginning of his presentation.

The researcher, who is also the director of the Obesity and Metabolic Medicine Group, stated that obesity can no longer be seen as a single homogeneous pathology but rather should be viewed as clinical conditions affecting various subpopulations that respond differently to treatments.

Patients are currently diagnosed with obesity based on BMI value or waist measurement, as recommended by current clinical guidelines, but this method contributes to treating obesity subtypes as if they were identical.

“By taking into account the patient’s specificities, we can identify individuals who are likely to progress rapidly with the disease and those who will respond well to targeted interventions,” said Dr. Le Roux, emphasizing that this approach also contributes to reducing public health system costs.

Researchers proposed creating a map that allows the visualization of the distinct characteristics of patients with obesity, such as the presence of associated diseases like hypertension and diabetes. One of the main challenges of the project was finding a way to share sensitive data among SOPHIA partners without compromising individual privacy. The solution was the creation of a federated database.

In practice, this system allows academic and industry partners to send data to a central server, which keeps them protected. “We wanted to reach the optimal point, where we can have maximum utility and maximum privacy protection using technology. Researchers can then obtain statistics, enabling the analysis of large data sets without compromising security,” Dr. Le Roux explained.

Most patients analyzed in the project fall into the main group, where “the higher the weight, the greater the risk” for associated diseases, he added. However, the project allows for specifically visualizing patients with alterations related to high blood pressure, liver function, lipid profile, blood glucose, and inflammation.

“Subclassifying diseases helps us better understand the various mechanisms by which these pathologies arise and why some individuals exhibit unexpected phenotypic patterns of increased susceptibility or resilience. For example, patients with inflammation changes have a much higher risk for developing type 2 diabetes, rheumatoid arthritis, and liver failure,” said Dr. Le Roux.

In addition to visualizing the associated diseases of each participant, SOPHIA, in which 30 partners in Europe, the Middle East, and the United States participate, also features treatment overlap, which allows researchers to track individual responses to the treatment.

“With this overlap, we confirm something that many know: When treating people with type 2 diabetes, whether through lifestyle changes, medication, or surgery, weight loss is lower. But, to our surprise, we found that patients with inflammation-related changes had greater weight loss. This finding tells us that some groups benefit more, and others less,” said Dr. Le Roux.

This analysis is particularly interesting when it comes to bariatric surgery, he continued. “Often, the surgeon performs an incredibly well-done gastric bypass, and the response is not as expected. In this case, we can say that it is purely biology,” said Dr. Le Roux, who concluded the presentation by discussing the benefits of this approach for good patient counseling.

“When we talk about ‘obesities’ and not ‘obesity,’ we can also conduct our consultations more carefully by explaining to our patients that if they do not respond to treatment, it is not their fault, not because they did something wrong, but because of something that is not usually taken into account, such as the presence of comorbidities, or even personal characteristics and lifestyle, such as age and smoking,” said Dr. Le Roux.

During a lecture at the 2024 International Congress on Obesity in São Paulo, Brazil, Dr. Carel Le Roux, a South African researcher, reflected on the Stratification of Obesity Phenotypes to Optimize Future Therapy (SOPHIA) project. The effort, of which Dr. Le Roux is a leader, involves using federated data and reframing obesity as a set of diseases, each with its own peculiarities and treatment needs.

A collaborative research initiative led by the European Union, the SOPHIA project is a public-private partnership that brings together healthcare professionals, universities, industry leaders, and patient organizations to rethink how we understand and treat obesity, considering factors beyond body mass index (BMI).

“We need to ask ourselves, ‘Is obesity a disease? Or, in fact, does ‘obesity’ refer to multiple diseases that lead to excess adipose tissue?’ ” Dr. Le Roux asked at the beginning of his presentation.

The researcher, who is also the director of the Obesity and Metabolic Medicine Group, stated that obesity can no longer be seen as a single homogeneous pathology but rather should be viewed as clinical conditions affecting various subpopulations that respond differently to treatments.

Patients are currently diagnosed with obesity based on BMI value or waist measurement, as recommended by current clinical guidelines, but this method contributes to treating obesity subtypes as if they were identical.

“By taking into account the patient’s specificities, we can identify individuals who are likely to progress rapidly with the disease and those who will respond well to targeted interventions,” said Dr. Le Roux, emphasizing that this approach also contributes to reducing public health system costs.

Researchers proposed creating a map that allows the visualization of the distinct characteristics of patients with obesity, such as the presence of associated diseases like hypertension and diabetes. One of the main challenges of the project was finding a way to share sensitive data among SOPHIA partners without compromising individual privacy. The solution was the creation of a federated database.

In practice, this system allows academic and industry partners to send data to a central server, which keeps them protected. “We wanted to reach the optimal point, where we can have maximum utility and maximum privacy protection using technology. Researchers can then obtain statistics, enabling the analysis of large data sets without compromising security,” Dr. Le Roux explained.

Most patients analyzed in the project fall into the main group, where “the higher the weight, the greater the risk” for associated diseases, he added. However, the project allows for specifically visualizing patients with alterations related to high blood pressure, liver function, lipid profile, blood glucose, and inflammation.

Rural regions like the one surrounding a southern Iowa town used to have a lot more babies and many more places to give birth to them.

At least 41 Iowa hospitals have shuttered their labor and delivery units since 2000. Those facilities, representing about a third of all Iowa hospitals, are located mostly in rural areas where birth numbers have plummeted. In some Iowa counties, annual numbers of births have fallen by three quarters since the height of the baby boom in the 1950s and 1960s, when many rural hospitals were built or expanded, state and federal records show.

Similar trends are playing out nationwide, as hospitals struggle to maintain staff and facilities to safely handle dwindling numbers of births. More than half of rural US hospitals now lack the service.

“People just aren’t having as many kids,” said Addie Comegys, who lives in southern Iowa and has regularly traveled 45 minutes each way for prenatal checkups at Oskaloosa’s hospital this summer. Her mother had six children, starting in the 1980s, when big families didn’t seem so rare.

“Now, if you have three kids, people are like, ‘Oh my gosh, are you ever going to stop?’ ” said Ms. Comegys, 29, who is expecting her second child in late August.

These days, many Americans choose to have small families or no children at all. Modern birth control methods help make such decisions stick. The trend is amplified in small towns when young adults move away, taking any childbearing potential with them.

Hospital leaders who close obstetrics units often cite declining birth numbers, along with staffing challenges and financial losses. The closures can be a particular challenge for pregnant women who lack the reliable transportation and flexible schedules needed to travel long distances for prenatal care and birthing services.

The baby boom peaked in 1957, when about 4.3 million children were born in the United States. The annual number of births dropped below 3.7 million by 2022, even though the overall US population nearly doubled over that same period.

West Virginia has seen the steepest decline in births, a 62% drop in those 65 years, according to federal data. Iowa’s births dropped 43% over that period. Of the state’s 99 counties, just four — all urban or suburban — recorded more births.

Births have increased in only 13 states since 1957. Most of them, such as Arizona, California, Florida, and Nevada, are places that have attracted waves of newcomers from other states and countries. But even those states have had obstetrics units close in rural areas.

In Iowa, Oskaloosa’s hospital has bucked the trend and kept its labor and delivery unit open, partly by pulling in patients from 14 other counties. Last year, the hospital even managed the rare feat of recruiting two obstetrician-gynecologists to expand its services.

The publicly owned hospital, called Mahaska Health, expects to deliver 250 babies this year, up from about 160 in previous years, CEO Kevin DeRonde said.

“It’s an essential service, and we needed to keep it going and grow it,” Mr. DeRonde said.

Many of the US hospitals that are now dropping obstetrics units were built or expanded in the mid-1900s, when America went on a rural-hospital building spree, thanks to federal funding from the Hill-Burton Act.

“It was an amazing program,” said Brock Slabach, chief operations officer for the National Rural Health Association. “Basically, if you were a county that wanted a hospital, they gave you the money.”

Mr. Slabach said that in addition to declining birth numbers, obstetrics units are experiencing a drop in occupancy because most patients go home after a night or two. In the past, patients typically spent several days in the hospital after giving birth.

Dwindling caseloads can raise safety concerns for obstetrics units.

A study published in JAMA in 2023 found that women were more likely to suffer serious complications if they gave birth in rural hospitals that handled 110 or fewer births a year. The authors said they didn’t support closing low-volume units because that could lead more women to have complications related to traveling for care. Instead, they recommended improving training and coordination among rural health providers.

Stephanie Radke, MD, a University of Iowa obstetrics and gynecology professor who studies access to birthing services, said it is almost inevitable that when rural birth numbers plunge, some obstetrics units will close. “We talk about that as a bad event, but we don’t really talk about why it happens,” she said.

Dr. Radke said maintaining a set number of obstetrics units is less important than ensuring good care for pregnant women and their babies. It’s difficult to maintain quality of care when the staff doesn’t consistently practice deliveries, she said, but it is hard to define that line. “What is realistic?” she said. “I don’t think a unit should be open that only delivers 50 babies a year.”

In some cases, she said, hospitals near each other have consolidated obstetrics units, pooling their resources into one program that has enough staffers and handles sufficient cases. “You’re not always really creating a care desert when that happens,” she said.

The decline in births has accelerated in many areas in recent years. Kenneth Johnson, a sociology professor and demographer at the University of New Hampshire, said it is understandable that many rural hospitals have closed obstetrics units. “I’m actually surprised some of them have lasted as long as they have,” he said.

Dr. Johnson said rural areas that have seen the steepest population declines tend to be far from cities and lack recreational attractions, such as mountains or large bodies of water. Some have avoided population losses by attracting immigrant workers, who tend to have larger families in the first generation or two after they move to the United States, he said.

Katy B. Kozhimannil, a University of Minnesota health policy professor who studies rural issues, said declining birth numbers and obstetric unit closures can create a vicious cycle. Fewer babies being born in a region can lead a birthing unit to shutter. Then the loss of such a unit can discourage young people from moving to the area, driving birth numbers even lower.

In many regions, people with private insurance, flexible schedules, and reliable transportation choose to travel to larger hospitals for their prenatal care and to give birth, Dr. Kozhimannil said. That leaves rural hospitals with a larger proportion of patients on Medicaid, a public program that pays about half what private insurance pays for the same services, she said.

Iowa ranks near the bottom of all states for obstetrician-gynecologists per capita. But Oskaloosa’s hospital hit the jackpot last year, when it recruited Taylar Swartz Summers, DO, and Garth Summers, DO, a married couple who both recently finished their obstetrics training. Dr. Swartz Summers grew up in the area, and she wanted to return to serve women there.

She hopes the number of obstetrics units will level off after the wave of closures. “It’s not even just for delivery, but we need access just to women’s healthcare in general,” she said. “I would love to see women’s healthcare be at the forefront of our government’s mind.”

Dr. Swartz Summers noted that the state has only one obstetrics training program, which is at the University of Iowa. She said she and her husband plan to help spark interest in rural obstetrics by hosting University of Iowa residency rotations at the Oskaloosa hospital.

Ms. Comegys, a patient of Dr. Swartz Summer’s, could have chosen a hospital birthing center closer to her home, but she wasn’t confident in its quality. Other hospitals in her region had shuttered their obstetrics units. She is grateful to have a flexible job, a reliable car, and a supportive family, so she can travel to Oskaloosa for checkups and to give birth there. She knows many other women are not so lucky, and she worries other obstetrics units are at risk.

“It’s sad, but I could see more closing,” she said.

Almost 1 in 10 pregnant people infected with COVID-19 end up developing long COVID, according to a study published in Obstetrics & Gynecology.

Researchers at University of Utah Health looked at the medical records of more than 1500 people who got COVID-19 while pregnant and checked their self-reported symptoms at least 6 months after infection, according to a news release from the school.

The scientists discovered that 9.3% of those people reported long COVID symptoms, such as fatigue and issues in their gut. 

To make sure those long COVID symptoms were not actually symptoms of pregnancy, the research team did a second analysis of people who reported symptoms more than 12 weeks after giving birth. The risk of long COVID was about the same as in the first analysis.

“It was surprising to me that the prevalence was that high,” Torri D. Metz, MD, vice chair for research of obstetrics and gynecology at the school and co-leader of the study, said in the release. “This is something that does continue to affect otherwise reasonably healthy and young populations.”

The school said this is the first study to look at long COVID risks in pregnant people. Previous research found other dangers for pregnant people who get COVID, such as a higher chance of hospitalization or death, or complications such as preterm birth.

In the general population, research shows that 10%-20% of people who get COVID develop long COVID.

Dr. Metz said healthcare providers need to remain alert about long COVID, including in pregnant people.

“We need to have this on our radar as we’re seeing patients. It’s something we really don’t want to miss. And we want to get people referred to appropriate specialists who treat long COVID,” she said.

Almost 1 in 10 pregnant people infected with COVID-19 end up developing long COVID, according to a study published in Obstetrics & Gynecology.

Researchers at University of Utah Health looked at the medical records of more than 1500 people who got COVID-19 while pregnant and checked their self-reported symptoms at least 6 months after infection, according to a news release from the school.

The scientists discovered that 9.3% of those people reported long COVID symptoms, such as fatigue and issues in their gut.

Ovarian cancer risk was higher in women with endometriosis overall and markedly increased in those with severe forms, a large population-based cohort study found.

The findings, published in JAMA, suggest these women may benefit from counseling on ovarian cancer risk and prevention and potentially from targeted screening, according to a group led by Mollie E. Barnard, ScD, of the Huntsman Cancer Institute at the University of Utah in Salt Lake City.

While the absolute increase in number of cases was small, endometriosis patients overall had a more than fourfold higher risk for any type of ovarian cancer. Those with more severe forms, such as ovarian endometriomas or deep infiltrating endometriosis, had a nearly 10-fold higher risk of any type of ovarian cancer. In addition, those with more severe endometriosis had a 19-fold higher risk of type 1 (slow-growing) ovarian cancer and almost three times the risk of the more aggressive type 2.

“Given the rarity of ovarian cancer, the excess risk was relatively small, with 10-20 additional cases per 10,000 women. Nevertheless, women with endometriosis, notably the more severe subtypes, may be an important population for targeted cancer screening and prevention studies,” said corresponding author Karen C. Schliep, PhD, MSPH, associate professor in the university’s Division of Public Health.

Prior studies have shown modest associations between endometriosis and ovarian cancer, Dr. Schliep said in an interview. A 2021 systematic review and meta-analysis found endometriosis conferred nearly double the risk of ovarian cancer, although associations varied by ovarian cancer histotype. Few studies have been large enough to assess associations between endometriosis types — including superficial or peritoneal endometriosis vs ovarian endometriomas or deep infiltrating endometriosis and ovarian cancer histotypes such as low-grade serous, endometrioid, clear cell, and mucinous carcinomas (type 1), and the most aggressive and lethal form, high-grade serous type 2, she said in an interview. “Our large health administrative database of over 11 million individuals with linked electronic health and cancer registry data allowed us to answer this as yet poorly studied research question.”
 

Study Details

Drawing on Utah electronic health records from 1992 to 2019, the investigators matched 78,893 women with endometriosis in a 1:5 ratio to unaffected women. Cases were categorized as superficial endometriosis, ovarian endometriomas, deep infiltrating endometriosis, or other, and the types of endometriosis were matched to ovarian cancer histotypes.

The mean age of patients at first endometriosis diagnosis was 36 and the mean follow-up was 12 years. Compared with controls, endometriosis patients were more likely to be nulliparous (31% vs 24%) and to have had a hysterectomy (39% vs 6%) during follow-up.

There were 596 reported cases of ovarian cancer in the cohort. Those with incident endometriosis were 4.2 times more likely to develop ovarian cancer (95% CI, 3.59-4.91), 7.48 times more likely to develop type 1 ovarian cancer (95% CI, 5.80-9.65), and 2.70 times more likely to develop type 2 ovarian cancer (95% CI, 2.09-3.49) compared with those without endometriosis.

The magnitudes of these associations varied by endometriosis subtype. Individuals diagnosed with deep infiltrating endometriosis and/or ovarian endometriomas had 9.66 times the risk of ovarian cancer vs individuals without endometriosis (95% CI, 7.77-12.00). “Women with, compared to without, more severe endometriosis had a 19-fold higher risk of type 1 ovarian cancer, including endometrioid, clear cell, mucinous, and low-grade serous,” Dr. Schliep said, with associated risk highest for malignant subtypes such as clear cell and endometrioid carcinoma (adjusted hazard ratios, 11.15 and 7.96, respectively.

According to Dr. Schliep, physicians should encourage endometriosis patients to be aware of but not worry about ovarian cancer risk because the likelihood of developing it remains low. For their part, patients can reduce their risk of cancer through a balanced diet with low intake of alcohol, regular exercise, a healthy weight, and abstention from smoking.

Her message for researchers is as follows: “We need more studies that explore how different types of endometriosis impact different types of ovarian cancer risk. These studies will guide improved ovarian cancer screening and prevention strategies among women with severe endometriosis, with or without other important ovarian cancer risk factors such as BRCA 1/2 variations.”

An accompanying editorial called the Utah study “eloquent” and noted its distinguishing contribution of observing associations between subtypes of endometriosis with overall risk for ovarian cancer as well as histologic subtypes of epithelial ovarian cancer.

Nevertheless, Michael T. McHale, MD, of the Department of Obstetrics, Gynecology, and Reproductive Sciences at Moores Cancer Center, UC San Diego Health, University of California, expressed some methodological concerns. Although the authors attempted to control for key confounders, he noted, the dataset could not provide details on the medical management of endometriosis, such as oral contraceptives or gonadotropin-releasing hormone agonists. “Additionally, there is a possibility that women in the control cohort could have had undiagnosed endometriosis,” he wrote.

Furthermore, making clinical recommendations from these reported observations, particularly with respect to deep infiltrating endometriosis, would require a clear and consistent definition of this type in the dataset over the entire study interval from 1992 to 2019 and for the state of Utah, which the authors did not provide.

“Despite this potential challenge, the increased risk associated with deep infiltrating and/or ovarian endometriosis was clearly significant,” Dr. McHale wrote.

And although the absolute number of ovarian cancers is limited, in his view, the increased risk is sufficiently significant to advise women who have completed childbearing or have alternative fertility options to consider “more definitive surgery.”

This study was supported by multiple not-for-profit agencies, including the National Cancer Institute, the University of Utah, the National Center for Research Resources, the Utah Department of Health and Human Services, the Utah Cancer Registry, the US Centers for Disease Control and Prevention, the Huntsman Cancer Foundation, the National Institutes of Health, and Doris Duke Foundation. Dr. Barnard reported grants from the National Cancer Institute during the conduct of the study and personal fees from Epi Excellence LLC outside the submitted work. Other coauthors reported similar funding from nonprofit agencies or private research organizations. Dr Schliep disclosed no competing interests. Dr McHale reported educational consulting for Eisai Training outside the submitted work.
