Two Diets Linked to Improved Cognition, Slowed Brain Aging
An intermittent fasting (IF) diet and a standard healthy living (HL) diet focused on healthy foods both lead to weight loss, reduced insulin resistance (IR), and slowed brain aging in older overweight adults with IR, new research showed. However, neither diet has an effect on Alzheimer’s disease (AD) biomarkers.
Although investigators found both diets were beneficial, some outcomes were more robust with the IF diet.
“The study provides a blueprint for assessing brain effects of dietary interventions and motivates further research on intermittent fasting and continuous diets for brain health optimization,” wrote the investigators, led by Dimitrios Kapogiannis, MD, chief, human neuroscience section, National Institute on Aging, and adjunct associate professor of neurology, the Johns Hopkins University School of Medicine.
The findings were published online in Cell Metabolism.
Cognitive Outcomes
The prevalence of IR — reduced cellular sensitivity to insulin that’s a hallmark of type 2 diabetes — increases with age and obesity, adding to an increased risk for accelerated brain aging as well as AD and related dementias (ADRD) in older adults who have overweight.
Studies reported healthy diets promote overall health, but it’s unclear whether, and to what extent, they improve brain health beyond general health enhancement.
Researchers used multiple brain and cognitive measures to assess dietary effects on brain health, including peripherally harvested neuron-derived extracellular vesicles (NDEVs) to probe neuronal insulin signaling; MRI to investigate the pace of brain aging; magnetic resonance spectroscopy (MRS) to measure brain glucose, metabolites, and neurotransmitters; and NDEVs and cerebrospinal fluid to derive biomarkers for AD/ADRD.
The study included 40 cognitively intact overweight participants with IR, mean age 63.2 years, 60% women, and 62.5% White. Their mean body weight was 97.1 kg and mean body mass index (BMI) was 34.4.
Participants were randomly assigned to 8 weeks of an IF diet or a HL diet that emphasizes fruits, vegetables, whole grains, lean proteins, and low-fat dairy and limits added sugars, saturated fats, and sodium.
The IF diet involved following the HL diet for 5 days per week and restricting calories to a quarter of the recommended daily intake for 2 consecutive days.
Both diets reduced neuronal IR and had comparable effects in improving insulin signaling biomarkers in NDEVs, reducing brain glucose on MRS, and improving blood biomarkers of carbohydrate and lipid metabolism.
Using MRI, researchers also assessed brain age, an indication of whether the brain appears older or younger than an individual’s chronological age. There was a decrease of 2.63 years with the IF diet (P = .05) and 2.42 years with the HL diet (P < .001) in the anterior cingulate and ventromedial prefrontal cortex.
Both diets improved executive function and memory, with those following the IF diet benefiting more in strategic planning, switching between two cognitively demanding tasks, cued recall, and other areas.
Hypothesis-Generating Research
AD biomarkers including amyloid beta 42 (Aß42), Aß40, and plasma phosphorylated-tau181 did not change with either diet, a finding that investigators speculated may be due to the short duration of the study. Light-chain neurofilaments increased across groups with no differences between the diets.
In other findings, BMI decreased by 1.41 with the IF diet and by 0.80 with the HL diet, and a similar pattern was observed for weight. Waist circumference decreased in both groups with no significant differences between diets.
An exploratory analysis showed executive function improved with the IF diet but not with the HL diet in women, whereas it improved with both diets in men. BMI and apolipoprotein E and SLC16A7 genotypes also modulated diet effects.
Both diets were well tolerated. The most frequent adverse events were gastrointestinal and occurred only with the IF diet.
The authors noted the findings are preliminary and results are hypothesis generating. Study limitations included the study’s short duration and its power to detect anything other than large to moderate effect size changes and differences between the diets. Researchers also didn’t acquire data on dietary intake, so lapses in adherence can’t be excluded. However, the large decreases in BMI, weight, and waist circumference with both diets indicated high adherence.
The study was supported by the National Institutes of Health’s National Institute on Aging. The authors reported no competing interests.

FROM CELL METABOLISM
Risk of MACE Comparable Among Biologic Classes for Psoriasis, PsA
TOPLINE:
a database analysis finds.
METHODOLOGY:
- Data from the TriNetX health records database included 32,758 patients treated with TNF inhibitors (TNFi, 62.9%), interleukin-17 inhibitors (IL-17i, 15.4%), IL-23i (10.7%), and IL-12i/IL-23i (10.7%).
- The researchers calculated time-dependent risk for MACE using multinomial Cox proportional hazard ratios. The reference was TNFi exposure.
- Subset analyses compared MACE in patients with and without existing cardiovascular disease.
TAKEAWAY:
- Compared with TNFi use, there was no difference in the incidence of MACE events in the IL-17i, IL-23i, or IL-12i/IL-23i group.
- There were also no significant differences between biologic groups in the incidence of congestive heart failure, myocardial infarction, or cerebral vascular accident/stroke.
IN PRACTICE:
Despite some concern about increased risk for MACE with TNFi use, this study suggests no special risk for patients with psoriasis or PsA associated with TNFi vs other biologics. “Given our results, as it pertains to MACE, prescribers shouldn’t favor any one biologic class over another,” said lead investigator Shikha Singla, MD, medical director of the Psoriatic Arthritis Program at Medical College of Wisconsin in Milwaukee, Wisconsin.
SOURCE:
Bonit Gill, MD, a second-year fellow at Medical College of Wisconsin, presented the study as a poster at the annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.
LIMITATIONS:
The study’s retrospective nature makes it impossible to prove causation and the patients included in the study were from Wisconsin, which may limit generalizability.
DISCLOSURES:
Dr. Gill had no relevant financial disclosures. Other study authors participated in trials or consulted for AbbVie, AstraZeneca, Novartis, Eli Lilly, Janssen, and UCB.

Study Links Newer Shingles Vaccine to Delayed Dementia Diagnosis
The study builds on previous observations of a reduction in dementia risk with the older live shingles vaccine and reports a delay in dementia diagnosis of 164 days with the newer recombinant version, compared with the live vaccine.
“Given the prevalence of dementia, a delay of 164 days in diagnosis would not be a trivial effect at the public health level. It’s a big enough effect that if there is a causality it feels meaningful,” said senior author Paul Harrison, DM, FRCPsych, professor of psychiatry at the University of Oxford, Oxford, England.
But Dr. Harrison stressed that the study had not proven that the shingles vaccine reduced dementia risk.
“The design of the study allows us to do away with many of the confounding effects we usually see in observational studies, but this is still an observational study, and as such it cannot prove a definite causal effect,” he said.
The study was published online on July 25 in Nature Medicine.
‘Natural Experiment’
Given the risk for deleterious consequences of shingles, vaccination is now recommended for older adults in many countries. The previously used live shingles vaccine (Zostavax) is being replaced in most countries with the new recombinant shingles vaccine (Shingrix), which is more effective at preventing shingles infection.
The current study made use of a “natural experiment” in the United States, which switched over from use of the live vaccine to the recombinant vaccine in October 2017.
Researchers used electronic heath records to compare the incidence of a dementia diagnosis in individuals who received the live shingles vaccine prior to October 2017 with those who received the recombinant version after the United States made the switch.
They also used propensity score matching to further control for confounding factors, comparing 103,837 individuals who received a first dose of the live shingles vaccine between October 2014 and September 2017 with the same number of matched people who received the recombinant vaccine between November 2017 and October 2020.
Results showed that within the 6 years after vaccination, the recombinant vaccine was associated with a delay in the diagnosis of dementia, compared with the live vaccine. Specifically, receiving the recombinant vaccine was associated with a 17% increase in diagnosis-free time, translating to 164 additional days lived without a diagnosis of dementia in those subsequently affected.
As an additional control, the researchers also found significantly lower risks for dementia in individuals receiving the new recombinant shingles vaccine vs two other vaccines commonly used in older people: influenza and tetanus/diphtheria/pertussis vaccines, with increases in diagnosis-free time of 14%-27%.
Reduced Risk or Delayed Diagnosis?
Speaking at a Science Media Centre press conference on the study, lead author Maxime Taquet, PhD, FRCPsych, clinical lecturer in psychiatry at the University of Oxford, noted that the total number of dementia cases were similar in the two shingles vaccine groups by the end of the 6-year follow-up period but there was a difference in the time at which they received a diagnosis of dementia.
“The study suggests that rather than actually reducing dementia risk, the recombinant vaccine delays the onset of dementia compared to the live vaccine in patients who go on to develop the condition,” he explained.
But when comparing the recombinant vaccine with the influenza and tetanus/diphtheria/pertussis vaccines there was a clear reduction in dementia risk itself, Dr. Taquet reported.
“It might well be that the live vaccine has a potential effect on the risk of dementia itself and therefore the recombinant vaccine only shows a delay in dementia compared to the live vaccine, but both of them might decrease the overall risk of dementia,” he suggested.
But the researchers cautioned that this study could not prove causality.
“While the two groups were very carefully matched in terms of factors that might influence the development of dementia, we still have to be cautious before assuming that the vaccine is indeed causally reducing the risk of onset of dementia,” Dr. Harrison warned.
The researchers say the results would need to be confirmed in a randomized trial, which may have to be conducted in a slightly younger age group, as currently shingles vaccine is recommended for all older individuals in the United Kingdom.
Vaccine recommendations vary from country to country, Dr. Harrison added. In the United States, the Centers for Disease Control and Prevention recommends the recombinant shingles vaccine for all adults aged 50 years or older.
In the meantime, it would be interesting to see whether further observational studies in other countries find similar results as this US study, Dr. Harrison said.
Mechanism Uncertain
Speculating on a possible mechanism behind the findings, Dr. Harrison suggested two plausible explanations.
“First, it is thought that the herpes virus could be one of many factors that could promote dementia, so a vaccine that stops reactivation of this virus might therefore be delaying that process,” he noted.
The other possibility is that adjuvants included in the recombinant vaccine to stimulate the immune system might have played a role.
“We don’t have any data on the mechanism, and thus study did not address that, so further studies are needed to look into this,” Dr. Harrison said.
Stronger Effect in Women
Another intriguing finding is that the association with the recombinant vaccine and delayed dementia diagnosis seemed to be stronger in women vs men.
In the original study of the live shingles vaccine, a protective effect against dementia was shown only in women.
In the current study, the delay in dementia diagnosis was seen in both sexes but was stronger in women, showing a 22% increased time without dementia in women versus a 13% increased time in men with the recombinant versus the live vaccine.
As expected, the recombinant vaccine was associated with a lower risk for shingles disease vs the live vaccine (2.5% versus 3.5%), but women did not have a better response than men did in this respect.
“The better protection against shingles with the recombinant vaccine was similar in men and women, an observation that might be one reason to question the possible mechanism behind the dementia effect being better suppression of the herpes zoster virus by the recombinant vaccine,” Dr. Harrison commented.
Though these findings are not likely to lead to any immediate changes in policy regarding the shingles vaccine, Dr. Harrison said it would be interesting to see whether uptake of the vaccine increased after this study.
He estimated that, currently in the United Kingdom, about 60% of older adults choose to have the shingles vaccine. A 2020 study in the United States found that only about one-third of US adults over 60 had received the vaccine.
“It will be interesting to see if that figure increases after these data are publicized, but I am not recommending that people have the vaccine specifically to lower their risk of dementia because of the caveats about the study that we have discussed,” he commented.
Outside Experts Positive
Outside experts, providing comment to the Science Media Centre, welcomed the new research.
“ The study is very well-conducted and adds to previous data indicating that vaccination against shingles is associated with lower dementia risk. More research is needed in future to determine why this vaccine is associated with lower dementia risk,” said Tara Spires-Jones, FMedSci, president of the British Neuroscience Association.
The high number of patients in the study and the adjustments for potential confounders are also strong points, noted Andrew Doig, PhD, professor of biochemistry, University of Manchester, Manchester, England.
“This is a significant result, comparable in effectiveness to the recent antibody drugs for Alzheimer’s disease,” Dr. Doig said. “Administering the recombinant shingles vaccine could well be a simple and cheap way to lower the risk of Alzheimer’s disease.”
Dr. Doig noted that a link between herpes zoster infection and the onset of dementia has been suspected for some time, and a trial of the antiviral drug valacyclovir against Alzheimer’s disease is currently underway.
In regard to the shingles vaccine, he said a placebo-controlled trial would be needed to prove causality.
“We also need to see how many years the effect might last and whether we should vaccinate people at a younger age. We know that the path to Alzheimer’s can start decades before any symptoms are apparent, so the vaccine might be even more effective if given to people in their 40s or 50s,” he said.
Dr. Harrison and Dr. Taquet reported no disclosures. Dr. Doig is a founder, director, and consultant for PharmaKure, which works on Alzheimer’s drugs and diagnostics. Other commentators declared no disclosures.

The study builds on previous observations of a reduction in dementia risk with the older live shingles vaccine and reports a delay in dementia diagnosis of 164 days with the newer recombinant version, compared with the live vaccine.
“Given the prevalence of dementia, a delay of 164 days in diagnosis would not be a trivial effect at the public health level. It’s a big enough effect that if there is a causality it feels meaningful,” said senior author Paul Harrison, DM, FRCPsych, professor of psychiatry at the University of Oxford, Oxford, England.
But Dr. Harrison stressed that the study had not proven that the shingles vaccine reduced dementia risk.
“The design of the study allows us to do away with many of the confounding effects we usually see in observational studies, but this is still an observational study, and as such it cannot prove a definite causal effect,” he said.
The study was published online on July 25 in Nature Medicine.
‘Natural Experiment’
Given the risk for deleterious consequences of shingles, vaccination is now recommended for older adults in many countries. The previously used live shingles vaccine (Zostavax) is being replaced in most countries with the new recombinant shingles vaccine (Shingrix), which is more effective at preventing shingles infection.
The current study made use of a “natural experiment” in the United States, which switched over from use of the live vaccine to the recombinant vaccine in October 2017.
Researchers used electronic heath records to compare the incidence of a dementia diagnosis in individuals who received the live shingles vaccine prior to October 2017 with those who received the recombinant version after the United States made the switch.
They also used propensity score matching to further control for confounding factors, comparing 103,837 individuals who received a first dose of the live shingles vaccine between October 2014 and September 2017 with the same number of matched people who received the recombinant vaccine between November 2017 and October 2020.
Results showed that within the 6 years after vaccination, the recombinant vaccine was associated with a delay in the diagnosis of dementia, compared with the live vaccine. Specifically, receiving the recombinant vaccine was associated with a 17% increase in diagnosis-free time, translating to 164 additional days lived without a diagnosis of dementia in those subsequently affected.
As an additional control, the researchers also found significantly lower risks for dementia in individuals receiving the new recombinant shingles vaccine vs two other vaccines commonly used in older people: influenza and tetanus/diphtheria/pertussis vaccines, with increases in diagnosis-free time of 14%-27%.
Reduced Risk or Delayed Diagnosis?
Speaking at a Science Media Centre press conference on the study, lead author Maxime Taquet, PhD, FRCPsych, clinical lecturer in psychiatry at the University of Oxford, noted that the total number of dementia cases were similar in the two shingles vaccine groups by the end of the 6-year follow-up period but there was a difference in the time at which they received a diagnosis of dementia.
“The study suggests that rather than actually reducing dementia risk, the recombinant vaccine delays the onset of dementia compared to the live vaccine in patients who go on to develop the condition,” he explained.
But when comparing the recombinant vaccine with the influenza and tetanus/diphtheria/pertussis vaccines there was a clear reduction in dementia risk itself, Dr. Taquet reported.
“It might well be that the live vaccine has a potential effect on the risk of dementia itself and therefore the recombinant vaccine only shows a delay in dementia compared to the live vaccine, but both of them might decrease the overall risk of dementia,” he suggested.
But the researchers cautioned that this study could not prove causality.
“While the two groups were very carefully matched in terms of factors that might influence the development of dementia, we still have to be cautious before assuming that the vaccine is indeed causally reducing the risk of onset of dementia,” Dr. Harrison warned.
The researchers say the results would need to be confirmed in a randomized trial, which may have to be conducted in a slightly younger age group, as currently shingles vaccine is recommended for all older individuals in the United Kingdom.
Vaccine recommendations vary from country to country, Dr. Harrison added. In the United States, the Centers for Disease Control and Prevention recommends the recombinant shingles vaccine for all adults aged 50 years or older.
In the meantime, it would be interesting to see whether further observational studies in other countries find similar results as this US study, Dr. Harrison said.
Mechanism Uncertain
Speculating on a possible mechanism behind the findings, Dr. Harrison suggested two plausible explanations.
“First, it is thought that the herpes virus could be one of many factors that could promote dementia, so a vaccine that stops reactivation of this virus might therefore be delaying that process,” he noted.
The other possibility is that adjuvants included in the recombinant vaccine to stimulate the immune system might have played a role.
“We don’t have any data on the mechanism, and thus study did not address that, so further studies are needed to look into this,” Dr. Harrison said.
Stronger Effect in Women
Another intriguing finding is that the association with the recombinant vaccine and delayed dementia diagnosis seemed to be stronger in women vs men.
In the original study of the live shingles vaccine, a protective effect against dementia was shown only in women.
In the current study, the delay in dementia diagnosis was seen in both sexes but was stronger in women, showing a 22% increased time without dementia in women versus a 13% increased time in men with the recombinant versus the live vaccine.
As expected, the recombinant vaccine was associated with a lower risk for shingles disease vs the live vaccine (2.5% versus 3.5%), but women did not have a better response than men did in this respect.
“The better protection against shingles with the recombinant vaccine was similar in men and women, an observation that might be one reason to question the possible mechanism behind the dementia effect being better suppression of the herpes zoster virus by the recombinant vaccine,” Dr. Harrison commented.
Though these findings are not likely to lead to any immediate changes in policy regarding the shingles vaccine, Dr. Harrison said it would be interesting to see whether uptake of the vaccine increased after this study.
He estimated that, currently in the United Kingdom, about 60% of older adults choose to have the shingles vaccine. A 2020 study in the United States found that only about one-third of US adults over 60 had received the vaccine.
“It will be interesting to see if that figure increases after these data are publicized, but I am not recommending that people have the vaccine specifically to lower their risk of dementia because of the caveats about the study that we have discussed,” he commented.
Outside Experts Positive
Outside experts, providing comment to the Science Media Centre, welcomed the new research.
“ The study is very well-conducted and adds to previous data indicating that vaccination against shingles is associated with lower dementia risk. More research is needed in future to determine why this vaccine is associated with lower dementia risk,” said Tara Spires-Jones, FMedSci, president of the British Neuroscience Association.
The high number of patients in the study and the adjustments for potential confounders are also strong points, noted Andrew Doig, PhD, professor of biochemistry, University of Manchester, Manchester, England.
“This is a significant result, comparable in effectiveness to the recent antibody drugs for Alzheimer’s disease,” Dr. Doig said. “Administering the recombinant shingles vaccine could well be a simple and cheap way to lower the risk of Alzheimer’s disease.”
Dr. Doig noted that a link between herpes zoster infection and the onset of dementia has been suspected for some time, and a trial of the antiviral drug valacyclovir against Alzheimer’s disease is currently underway.
In regard to the shingles vaccine, he said a placebo-controlled trial would be needed to prove causality.
“We also need to see how many years the effect might last and whether we should vaccinate people at a younger age. We know that the path to Alzheimer’s can start decades before any symptoms are apparent, so the vaccine might be even more effective if given to people in their 40s or 50s,” he said.

The Rise of the Scribes
“We really aren’t taking care of records — we’re taking care of people.” — Dr. Lawrence Weed
What is the purpose of a progress note? Anyone? Yes, you there. “Insurance billing?” Yes, that’s a good one. Anyone else? “To remember what you did?” Excellent. Another? Yes, that’s right, for others to follow along in your care. These are all good reasons for a progress note to exist. But they aren’t the whole story. Let’s start at the beginning.
Charts were once a collection of paper sheets with handwritten notes. Sometimes illegible, sometimes beautiful, always efficient. A progress note back then could be just 10 characters, AK, LN2, X,X,X,X,X (with X’s marking nitrogen sprays). Then came the healthcare K-Pg event: the conversion to EMRs. Those doctors who survived evolved into computer programmers, creating blocks of text from a few keystrokes. But like toddler-sized Legos, the blocks made it impossible to build a note that is nuanced or precise. Worse yet, many notes consisting of blocks from one note added awkwardly to a new note, creating grotesque structures unrecognizable as anything that should exist in nature. Words and numbers, but no information.
Thanks to the eternity of EMR, these creations live on, hideous and useless. They waste not only the server’s energy but also our time. Few things are more maddening than scrolling to reach the bottom of another physician’s note only to find there is nothing there.
Whose fault is this? Anyone? Yes, that’s right, insurers. As there are probably no payers in this audience, let’s blame them. I agree, the crushing burden of documentation-to-get-reimbursed has forced us to create “notes” that add no value to us but add up points for us to get paid for them. CMS, payers, prior authorizations, and now even patients, it seems we are documenting for lots of people except for us. There isn’t time to satisfy all and this significant burden for every encounter is a proximate cause for doctors despair. Until now.
A fully formed, comprehensive, sometimes pretty note that satisfies all audiences. Dr. Larry Weed must be dancing in heaven. It was Dr. Weed who led us from the nicotine-stained logs of the 1950s to the powerful problem-based notes we use today, an innovation that rivals the stethoscope in its impact.
Professor Weed also predicted that computers would be important to capture and make sense of patient data, helping us make accurate diagnoses and efficient plans. Again, he was right. He would surely be advocating to take advantage of AI scribes’ marvelous ability to capture salient data and present it in the form of a problem-oriented medical record.
AI scribes will be ubiquitous soon; I’m fast and even for me they save time. They also allow, for the first time in a decade, to turn from the glow of a screen to actually face the patient – we no longer have to scribe and care simultaneously. Hallelujah. And yet, lest I disappoint you without a twist, it seems with AI scribes, like EMRs we lose a little something too.
Like self-driving cars or ChatGPT-generated letters, they remove cognitive loads. They are lovely when you have to multitask or are trying to recall a visit from hours (days) ago. Using them, you’ll feel faster, lighter, freer, happier. But what’s missing is the thinking. At the end, you have an exquisite note, but you didn’t write it. It has the salient points, but none of the mental work to create it. AI scribes subvert the valuable work of synthesis. That was the critical part of Dr. Weed’s discovery: writing problem-oriented notes helped us think better.
Writing allows for the friction that helps us process what is going on with a patient. It allows for the discovery of diagnoses and prompts plans. When I was an intern, one of my attendings would hand write notes, succinctly showing what he had observed and was thinking. He’d sketch diagrams in the chart, for example, to help illustrate how we’d work though the toxic, metabolic, and infectious etiologies of acute liver failure. Sublime.
The act of writing also helps remind us there is a person attached to these words. Like a handwritten sympathy card, it is intimate, human. Even using our EMR, I’d still often type sentences that help tell the patient’s story. “Her sister just died. Utterly devastated. I’ll forward chart to Bob (her PCP) to check in on her.” Or: “Scratch golfer wants to know why he is getting so many SCCs now. ‘Like bankruptcy, gradually then suddenly,’ I explained. I think I broke through.”
Since we’ve concluded the purpose of a note is mostly to capture data, AI scribes are a godsend. They do so with remarkable quality and efficiency. We’ll just have to remember if the diagnosis is unclear, then it might help to write the note out yourself. And even when done by the AI machine, we might add human touches now and again lest there be no art left in what we do.

New Criteria Distinguish Memory Disorder Often Misdiagnosed as Alzheimer’s
Proposed clinical criteria for a memory loss disorder that is often misdiagnosed as Alzheimer’s disease (AD) have been published.
The new criteria for limbic-predominant amnestic neurodegenerative syndrome (LANS) provide a framework for neurologists and other experts to classify the condition and offer a more precise diagnosis and potential treatments.
“In our clinical work, we see patients whose memory symptoms appear to mimic Alzheimer’s disease, but when you look at their brain imaging or biomarkers, it’s clear they don’t have Alzheimer’s. Until now, there has not been a specific medical diagnosis to point to, but now we can offer them some answers,” senior investigator David T. Jones, MD, said in a release.
The proposed criteria and the research behind it were published online in Brain Communications and will be presented at the Alzheimer›s Association International Conference in Philadelphia.
Already in Use
Predominant limbic degeneration has been linked to various underlying etiologies, older age, predominant impairment of episodic memory, and slow clinical progression, the investigators noted. However, they added, the neurologic syndrome associated with predominant limbic degeneration is undefined.
Developing clinical criteria and validating them “is critical to distinguish such a syndrome from those originating from neocortical degeneration, which may differ in underlying etiology, disease course, and therapeutic needs,” the investigators wrote.
The newly proposed clinical criteria apply to LANS, which is “highly associated with limbic-predominant age-related TDP-43 encephalopathy but also other pathologic entities.”
The criteria incorporate core, standard, and advanced features including older age at evaluation, mild clinical syndrome, disproportionate hippocampal atrophy, impaired semantic memory, limbic hypometabolism, absence of endocortical degeneration, and low likelihood of neocortical tau with highest, high, moderate, and low degrees of certainty.
“A detailed history of the clinical symptoms, which may be supported by neuropsychological testing, with the observation of disproportionate hippocampal atrophy and limbic degeneration on MRI/FDG yields a high confidence in a diagnosis of LANS, where the most likely symptom-driving proteinopathy is TDP-43 and not Alzheimer’s associated proteins,” the first author, Nick Corriveau-Lecavalier, PhD, assistant professor of neurology and psychology at Mayo Clinic, Rochester, Minnesota, told this news organization.
To validate the criteria, the investigators screened autopsied patients from Mayo Clinic and Alzheimer’s Disease Neuroimaging Initiative cohorts and applied the criteria to those with a predominant amnestic syndrome and those who had AD neuropathologic change, limbic-predominant age-related TDP-43 encephalopathy, or both pathologies at autopsy.
“The criteria effectively categorized these cases, with Alzheimer’s disease having the lowest likelihoods, limbic-predominant age-related TDP-43 encephalopathy patients having the highest likelihoods, and patients with both pathologies having intermediate likelihoods,” the investigators reported.
“Patients with high likelihoods had a milder and slower clinical course and more severe temporo-limbic degeneration compared to those with low likelihoods,” they added.
Dr. Corriveau-Lecavalier said the team is currently analyzing longitudinal cognitive and imaging trajectories in LANS over several years. “This will help us better understand how LANS and Alzheimer’s differ in their sequence of symptoms over time.”
It is important to understand that memory symptoms in old age are not “unequivocally” driven by Alzheimer’s and that LANS progresses more slowly and has a better prognosis than AD, he noted.
In addition, in vivo markers of TDP-43 are “on the horizon and can hopefully make their way to human research settings soon. This will help better understand the underlying molecular etiologies causing LANS and associated symptoms,” he said.
Dr. Corriveau-Lecavalier said the LANS criteria are ready for clinical use by experts in neurologic care. These criteria can be used to inform not only diagnosis but also prognosis, where this syndrome is associated with slow and mild progression and a memory-dominant profile.
He added that “the new criteria are also routinely used in our practice to make decisions about anti-amyloid treatment eligibility.”
Commenting on the research for this news organization, Rebecca M. Edelmayer, PhD, Alzheimer’s Association senior director of scientific engagement, said the research “exemplifies the great need to develop objective criteria for diagnosis and staging of Alzheimer’s and all other types of dementia and to create an integrated biological and clinical staging scheme that can be used effectively by physicians.”
“Advances in biomarkers will help to differentiate all types of dementia when incorporated into the diagnostic workup, but until those tools are available, a more succinct clinical criteria for diagnosis can be used to support a more personalized medicine approach to treatment, care, and enrollment into clinical studies,” said Dr. Edelmayer, who wasn’t involved in the research.
The research was funded in part by the National Institutes of Health and by the Robert Wood Johnson Foundation, the Elsie & Marvin Dekelboum Family Foundation, the Liston Family Foundation, the Edson Family, the Gerald A. and Henrietta Rauenhorst Foundation, and the Foundation Dr Corinne Schuler. Dr. Corriveau-Lecavalier and Dr. Edelmayer had no relevant conflicts of interest.

Developing clinical criteria and validating them “is critical to distinguish such a syndrome from those originating from neocortical degeneration, which may differ in underlying etiology, disease course, and therapeutic needs,” the investigators wrote.
The newly proposed clinical criteria apply to LANS, which is “highly associated with limbic-predominant age-related TDP-43 encephalopathy but also other pathologic entities.”
The criteria incorporate core, standard, and advanced features including older age at evaluation, mild clinical syndrome, disproportionate hippocampal atrophy, impaired semantic memory, limbic hypometabolism, absence of endocortical degeneration, and low likelihood of neocortical tau with highest, high, moderate, and low degrees of certainty.
“A detailed history of the clinical symptoms, which may be supported by neuropsychological testing, with the observation of disproportionate hippocampal atrophy and limbic degeneration on MRI/FDG yields a high confidence in a diagnosis of LANS, where the most likely symptom-driving proteinopathy is TDP-43 and not Alzheimer’s associated proteins,” the first author, Nick Corriveau-Lecavalier, PhD, assistant professor of neurology and psychology at Mayo Clinic, Rochester, Minnesota, told this news organization.
To validate the criteria, the investigators screened autopsied patients from Mayo Clinic and Alzheimer’s Disease Neuroimaging Initiative cohorts and applied the criteria to those with a predominant amnestic syndrome and those who had AD neuropathologic change, limbic-predominant age-related TDP-43 encephalopathy, or both pathologies at autopsy.
“The criteria effectively categorized these cases, with Alzheimer’s disease having the lowest likelihoods, limbic-predominant age-related TDP-43 encephalopathy patients having the highest likelihoods, and patients with both pathologies having intermediate likelihoods,” the investigators reported.
“Patients with high likelihoods had a milder and slower clinical course and more severe temporo-limbic degeneration compared to those with low likelihoods,” they added.
Dr. Corriveau-Lecavalier said the team is currently analyzing longitudinal cognitive and imaging trajectories in LANS over several years. “This will help us better understand how LANS and Alzheimer’s differ in their sequence of symptoms over time.”
It is important to understand that memory symptoms in old age are not “unequivocally” driven by Alzheimer’s and that LANS progresses more slowly and has a better prognosis than AD, he noted.
In addition, in vivo markers of TDP-43 are “on the horizon and can hopefully make their way to human research settings soon. This will help better understand the underlying molecular etiologies causing LANS and associated symptoms,” he said.
Dr. Corriveau-Lecavalier said the LANS criteria are ready for clinical use by experts in neurologic care. These criteria can be used to inform not only diagnosis but also prognosis, where this syndrome is associated with slow and mild progression and a memory-dominant profile.
He added that “the new criteria are also routinely used in our practice to make decisions about anti-amyloid treatment eligibility.”
Commenting on the research for this news organization, Rebecca M. Edelmayer, PhD, Alzheimer’s Association senior director of scientific engagement, said the research “exemplifies the great need to develop objective criteria for diagnosis and staging of Alzheimer’s and all other types of dementia and to create an integrated biological and clinical staging scheme that can be used effectively by physicians.”
“Advances in biomarkers will help to differentiate all types of dementia when incorporated into the diagnostic workup, but until those tools are available, a more succinct clinical criteria for diagnosis can be used to support a more personalized medicine approach to treatment, care, and enrollment into clinical studies,” said Dr. Edelmayer, who wasn’t involved in the research.
The research was funded in part by the National Institutes of Health and by the Robert Wood Johnson Foundation, the Elsie & Marvin Dekelboum Family Foundation, the Liston Family Foundation, the Edson Family, the Gerald A. and Henrietta Rauenhorst Foundation, and the Foundation Dr Corinne Schuler. Dr. Corriveau-Lecavalier and Dr. Edelmayer had no relevant conflicts of interest.

Will Treating High Blood Pressure Curb Dementia Risk?
High blood pressure is an established risk factor for neurodegeneration and cognitive decline.
Valentin Fuster, MD, president of Mount Sinai Fuster Heart Hospital in New York City, told this news organization. “There is no question in the literature that untreated high blood pressure may lead to dementia,” he said. “The open question is whether treating blood pressure is sufficient to decrease or stop the progress of dementia.”
Studies are mixed, but recent research suggests that addressing hypertension does affect the risk for dementia. A secondary analysis of the China Rural Hypertension Control Project reported at the American Heart Association (AHA) Scientific Sessions in 2023 but not yet published showed that the 4-year blood pressure–lowering program in adults aged 40 or older significantly reduced the risk for all-cause dementia and cognitive impairment.
Similarly, a post hoc analysis of the SPRINT MIND trial found that participants aged 50 or older who underwent intensive (< 120 mm Hg) vs standard (< 140 mm Hg) blood pressure lowering had a lower rate of probable dementia or mild cognitive impairment.
Other studies pointing to a benefit included a pooled individual participant analysis of five randomized controlled trials, which found class I evidence to support antihypertensive treatment to reduce the risk for incident dementia, and an earlier systematic review and meta-analysis of the association of blood pressure lowering with newly diagnosed dementia or cognitive impairment.
How It Might Work
Some possible mechanisms underlying the connection have emerged.
“Vascular disease caused by hypertension is clearly implicated in one form of dementia, called vascular cognitive impairment and dementia,” Andrew Moran, MD, PhD, associate professor of medicine at Columbia University Vagelos College of Physicians and Surgeons in New York City, told this news organization. “This category includes dementia following a stroke caused by uncontrolled hypertension.”
“At the same time, we now know that hypertension and other vascular risk factors can also contribute, along with other factors, to developing Alzheimer dementia,” he said. “Even without causing clinically evident stroke, vascular disease from hypertension can lead to subtle damage to the brain via ischemia, microhemorrhage, and atrophy.”
“It is well known that hypertension affects the vasculature, and the vasculature of the brain is not spared,” agreed Eileen Handberg, PhD, ARNP, a member of the Hypertension Workgroup at the American College of Cardiology (ACC) and a professor of medicine and director of the Cardiovascular Clinical Trials Program in the University of Florida, Gainesville, Florida. “Combine this with other mechanisms like inflammation and endothelial dysfunction, and add amyloid accumulation, and there is a deterioration in vascular beds leading to decreased cerebral blood flow,” she said.
Treating hypertension likely helps lower dementia risk through “a combination of reduced risk of stroke and also benefits on blood flow, blood vessel health, and reduction in neurodegeneration,” suggested Mitchell S.V. Elkind, MD, chief clinical science officer and past president of the AHA and a professor of neurology and epidemiology at Columbia University Irving Medical Center in New York City. “Midlife blood pressure elevations are associated with deposition of amyloid in the brain, so controlling blood pressure may reduce amyloid deposits and neurodegeneration.”
Time in Range or Treat to Target?
With respect to dementia risk, does treating hypertension to a specific target make a difference, or is it the time spent in a healthy blood pressure range?
“Observational studies and a post hoc analysis of the SPRINT MIND trial suggest that more time spent in a healthy blood pressure range or more stable blood pressure are associated with lower dementia risk,” Dr. Moran said. Citing results of the CHRC program and SPRINT MIND trial, he suggested that while a dose-response effect (the lower the blood pressure, the lower the dementia risk) hasn’t been definitively demonstrated, it is likely the case.
In his practice, Dr. Moran follows ACC/AHA guidelines and prescribes antihypertensives to get blood pressure below 130/80 mm Hg in individuals with hypertension who have other high-risk factors (cardiovascular disease, diabetes, chronic kidney disease, or high risk for these conditions). “The treatment rule for people with hypertension without these other risk factors is less clear — lowering blood pressure below 140/90 mm Hg is a must; I will discuss with patients whether to go lower than that.”
“The relative contributions of time in range versus treating to a target for blood pressure require further study,” said Dr. Elkind. “It is likely that the cumulative effect of blood pressure over time has a big role to play — and it does seem clear that midlife blood pressure is even more important than blood pressure late in life.”
That said, he added, “In general and all things being equal, I would treat to a blood pressure of < 120/80 mmHg,” given the SPRINT trial findings of greater benefits when treating to this systolic blood pressure goal. “Of course, if patients have side effects such as lightheadedness or dizziness or other medical conditions that require a higher target, then one would need to adjust the treatment targets.”
According to Dr. Fuster, targets should not be the focus because they vary. For example, the ACC/AHA guidelines use < 130/80 mm Hg, whereas the European Society of Hypertension guidelines and those of the American Academy of Family Physicians specify < 140/90 mm Hg and include age-based criteria. Because there are no studies comparing the outcomes of one set of guidelines vs another, Dr. Fuster thinks the focus should be on starting treatment as early as possible to prevent hypertension leading to dementia.
He pointed to the ongoing PESA trial, which uses brain MRI and other tests to characterize longitudinal associations among cerebral glucose metabolism, subclinical atherosclerosis, and cardiovascular risk factors in asymptomatic individuals aged 40-54. Most did not have hypertension at baseline.
A recently published analysis of a subcohort of 370 PESA participants found that those with persistent high cardiovascular risk and subclinical carotid atherosclerosis already had signs of brain metabolic decline, “suggesting that maintenance of cardiovascular health during midlife could contribute to reductions in neurodegenerative disease burden later in life,” wrote the investigators.
Is It Ever Too Late?
If starting hypertension treatment in midlife can help reduce the risk for cognitive impairment later, can treating later in life also help? “It’s theoretically possible, but it has to be proven,” Dr. Fuster said. “There are no data on whether there’s less chance to prevent the development of dementia if you start treating hypertension at age 70, for example. And we have no idea whether hypertension treatment will prevent progression in those who already have dementia.”
“Treating high blood pressure in older adults could affect the course of further progressive cognitive decline by improving vascular health and preventing strokes, which likely exacerbate nonvascular dementia,” Dr. Elkind suggested. “Most people with dementia have a combination of vascular and nonvascular dementia, so treating reversible causes wherever possible makes a difference.”
Dr. Elkind treats older patients with this in mind, he said, “even though most of the evidence points to the fact that it is blood pressure in middle age, not older age, that seems to have the biggest impact on later-life cognitive decline and dementia.” Like Dr. Fuster, he said, “the best strategy is to identify and treat blood pressure in midlife, before damage to the brain has advanced.”
Dr. Moran noted, “The latest science on dementia causes suggests it is difficult to draw a border between vascular and nonvascular dementia. So, as a practical matter, healthcare providers should consider that hypertension treatment is one of the best ways to prevent any category of dementia. This dementia prevention is added to the well-known benefits of hypertension treatment to prevent heart attacks, strokes, and kidney disease: ‘Healthy heart, healthy brain.’ ”
“Our BP [blood pressure] control rates overall are still abysmal,” Dr. Handberg added. Currently around one in four US adults with hypertension have it under control. Studies have shown that blood pressure control rates of 70%-80% are achievable, she said. “We can’t let patient or provider inertia continue.”
Dr. Handberg, Dr. Elkind, Dr. Moran, and Dr. Fuster declared no relevant conflicts of interest.

The Disturbing Sexual Trend With Real Health Consequences
This transcript has been edited for clarity.
Rachel S. Rubin, MD: I have an interesting topic for you — kind of shocking, actually. Some of you may have read a story earlier this year in The New York Times about the alarming rise among young people of choking or strangulation during sex. I spoke recently with Dr. Debby Herbenick about this concerning and violent trend. Dr. Herbenick is a well-known sexuality researcher and professor at the Indiana University School of Public Health. Welcome, Dr. Herbenick. Can you tell us about your research into this new trend?
Debby Herbenick, PhD: This is some of the most important research that I’ve done. I’ve been studying sexual behaviors and trends for about 14 years in terms of nationally representative studies that we do. Over time, we noticed a trend of increasing prevalence of rough sex practices.
Now, there’s always been a lot of sexual diversity in the world throughout history. But . The increase is mostly seen in teenagers and young adults.
We’ve done US nationally representative surveys as well as college campus representative surveys. We find that consistently across four campus representative surveys that 64% of women report having ever been choked during sex, and around 1 in 3 women (aged 18-24 years) throughout the whole country report having been choked during their most recent sexual activity with another person. They call it choking, but because it involves usually one hand — sometimes two hands or a forearm or an object, like a belt or a cord to tie around the neck — it is technically strangulation, because it’s external pressure to the neck to reduce or stop airflow or blood flow.
Dr. Rubin: These numbers are staggering, right? Everyone listening now is taking care of someone who has been strangled as a form of sexual pleasure. What does this mean from a safety perspective? And as doctors who are working these patients up for migraines and other health problems, what is the research showing?
Dr. Herbenick: We certainly are seeing people report recurrent headaches and ringing in the ears. There are things we’ve just barely scratched the surface on. Those of us working in this space believe that for anybody coming in for an unexplained stroke (for example, under age 50), you might consider some imaging to see if they have a dissection. We are hearing about people who, when you really probe to find out whether they’ve had pressure on the neck, they report that indeed that they have. So, we have to be thinking about neurologic symptoms. We know that they’re experiencing these at a pretty high rate.
For people who are engaging in these practices, they should know about the health risks, but we find that most don’t. They may have heard that if it’s really intense high pressure, that in rare cases people can die, but most have never heard of anything in between. So, they’re not necessarily connecting their voice hoarseness, or the recurrent headaches or the sensitivity to light they are having, to an experience of being choked. We need to be paying attention to neurologic symptoms.
Most physicians I speak with at conferences say that where they feel like they can step into this conversation is through anticipatory guidance and letting their patients know that they may have heard about this trend, and a lot of people are talking about the health consequences, and I want to share some information with you — not coming at it from a place of shame or judgment, but providing some information so that [patients] actually get some medical facts about this that could be lifesaving.
Dr. Rubin: I see such a big gap in my medical training. I was taught to say, “Hey, do you smoke, do you drink, do you do drugs? Do you have sex? Men, women, or both?”And that’s it. And then maybe use birth control, and don’t get an STD, thinking about herpes, syphilis, gonorrhea, and chlamydia. We weren’t really trained to talk to patients about what kind of sex they are having, or how to talk to patients in a way that is open-minded but also safety-conscious and how the concept of safe sex is more than wear a condom and use birth control.
This idea of rough sex practices and how to talk to teenagers — maybe our pediatricians should be talking about this. Where do we start in terms of how to bring up these conversations and with what level of detail?
Dr. Herbenick: We find that some young people are already being asked about some of the effects that might be showing on their bodies. It might be that their provider notices some bruising, or marks on their bodies from other types of rough sex practices like hitting and spanking. So that could be an entry point there. Choking is far more prevalent than slapping, so if you’re seeing some marks on the body, then it’s also a good time to ask about other practices they might be engaging in, especially higher risk ones like choking or strangulation. It’s offering some information and even saying, “Look, I’m not here to shame or judge you. I just want you to have some information about this” and giving them an opportunity to ask questions, too.
We have found that almost nobody talks with their nurse or doctor, even if they have symptoms after being choked or strangled during sex. Just 1% of women with choking-related symptoms, 7% of men, and far fewer trans and nonbinary young people report talking with a nurse or doctor, mostly because they say it doesn’t seem like a big deal. The symptoms got better quickly. Sometimes they’re afraid of being shamed for their sexual behavior, and that’s why they say they don’t talk with somebody.
They need some type of open-door anticipatory guidance as a way forward. Not everyone is comfortable directly asking whether a patient is engaging in this, but at least letting people know that you’ve heard of this behavior and providing some medical facts can give us a step forward with creating these conversations.
Dr. Rubin: Can you tell us where is this research going in terms of next steps? Other things that you’re looking at? And what are you excited about?
Dr. Herbenick: I’m excited about some work I did with a collaborator and colleague of mine, Dr. Keisuke Kawata, that he led a couple of years ago. He’s a neuroscientist. We were looking at potential cumulative effects on the brain. Now we’re taking some of that research into its next steps. We’re also doing more focused studies on other health consequences and hopefully finding out how we can test different educational messages and get people to learn more fact-based information about this, and then see if that is effective in prevention.
Dr. Rubin: It sounds like a public health campaign is really needed about how to get the word out there about the health consequences of these activities. We’re asking people often enough. In my clinic, I try to keep it open-ended — tell me what sex looks like. What does it look like, and what do you want it to look like? Because I see a lot of people with problems, but if they don’t bring it to me, I don’t necessarily bring it up to them. Until I heard your lecture, and I thought, oh my gosh, I’m not even asking the right questions. Are you hopeful that there will be more public health messaging out there?
Dr. Herbenick: I am. Years ago, when the child and adolescent choking game became a thing, the Centers for Disease Control and Prevention (CDC) issued reports about it and warnings to parents. And this is a far, far higher prevalence than that ever was. So, I would love to see organizations like the CDC and medical groups getting involved and educating their members and making statements. This is really impacting a huge generation of girls and women, because when it happens during sex between women and men, the choking is mostly happening to the girls and women. It’s also prevalent among sexual minority individuals. But we are talking about this whole generation of young women and what’s happening to their bodies and their brain health. We really need to step into this conversation.
Dr. Rubin: Very few of us are sexual medicine–trained physicians, and very few of us feel confident and comfortable talking about sexual health issues. But people are getting hurt. People are having real consequences of these behaviors because of our lack of education, knowledge, and even discussion around it. So thank you for doing this research, because had you not done this research, we wouldn’t have found out that 64% of people are engaging in these types of activities. That is not rare.

Rachel S. Rubin, MD: I have an interesting topic for you — kind of shocking, actually. Some of you may have read a story earlier this year in The New York Times about the alarming rise among young people of choking or strangulation during sex. I spoke recently with Dr. Debby Herbenick about this concerning and violent trend. Dr. Herbenick is a well-known sexuality researcher and professor at the Indiana University School of Public Health. Welcome, Dr. Herbenick. Can you tell us about your research into this new trend?
Debby Herbenick, PhD: This is some of the most important research that I’ve done. I’ve been studying sexual behaviors and trends for about 14 years in terms of nationally representative studies that we do. Over time, we noticed a trend of increasing prevalence of rough sex practices.
Now, there’s always been a lot of sexual diversity in the world throughout history. But . The increase is mostly seen in teenagers and young adults.
We’ve done US nationally representative surveys as well as college campus representative surveys. We find that consistently across four campus representative surveys that 64% of women report having ever been choked during sex, and around 1 in 3 women (aged 18-24 years) throughout the whole country report having been choked during their most recent sexual activity with another person. They call it choking, but because it involves usually one hand — sometimes two hands or a forearm or an object, like a belt or a cord to tie around the neck — it is technically strangulation, because it’s external pressure to the neck to reduce or stop airflow or blood flow.
Dr. Rubin: These numbers are staggering, right? Everyone listening now is taking care of someone who has been strangled as a form of sexual pleasure. What does this mean from a safety perspective? And as doctors who are working these patients up for migraines and other health problems, what is the research showing?
Dr. Herbenick: We certainly are seeing people report recurrent headaches and ringing in the ears. There are things we’ve just barely scratched the surface on. Those of us working in this space believe that for anybody coming in for an unexplained stroke (for example, under age 50), you might consider some imaging to see if they have a dissection. We are hearing about people who, when you really probe to find out whether they’ve had pressure on the neck, they report that indeed that they have. So, we have to be thinking about neurologic symptoms. We know that they’re experiencing these at a pretty high rate.
For people who are engaging in these practices, they should know about the health risks, but we find that most don’t. They may have heard that if it’s really intense high pressure, that in rare cases people can die, but most have never heard of anything in between. So, they’re not necessarily connecting their voice hoarseness, or the recurrent headaches or the sensitivity to light they are having, to an experience of being choked. We need to be paying attention to neurologic symptoms.
Most physicians I speak with at conferences say that where they feel like they can step into this conversation is through anticipatory guidance and letting their patients know that they may have heard about this trend, and a lot of people are talking about the health consequences, and I want to share some information with you — not coming at it from a place of shame or judgment, but providing some information so that [patients] actually get some medical facts about this that could be lifesaving.
Dr. Rubin: I see such a big gap in my medical training. I was taught to say, “Hey, do you smoke, do you drink, do you do drugs? Do you have sex? Men, women, or both?”And that’s it. And then maybe use birth control, and don’t get an STD, thinking about herpes, syphilis, gonorrhea, and chlamydia. We weren’t really trained to talk to patients about what kind of sex they are having, or how to talk to patients in a way that is open-minded but also safety-conscious and how the concept of safe sex is more than wear a condom and use birth control.
This idea of rough sex practices and how to talk to teenagers — maybe our pediatricians should be talking about this. Where do we start in terms of how to bring up these conversations and with what level of detail?
Dr. Herbenick: We find that some young people are already being asked about some of the effects that might be showing on their bodies. It might be that their provider notices some bruising, or marks on their bodies from other types of rough sex practices like hitting and spanking. So that could be an entry point there. Choking is far more prevalent than slapping, so if you’re seeing some marks on the body, then it’s also a good time to ask about other practices they might be engaging in, especially higher risk ones like choking or strangulation. It’s offering some information and even saying, “Look, I’m not here to shame or judge you. I just want you to have some information about this” and giving them an opportunity to ask questions, too.
We have found that almost nobody talks with their nurse or doctor, even if they have symptoms after being choked or strangled during sex. Just 1% of women with choking-related symptoms, 7% of men, and far fewer trans and nonbinary young people report talking with a nurse or doctor, mostly because they say it doesn’t seem like a big deal. The symptoms got better quickly. Sometimes they’re afraid of being shamed for their sexual behavior, and that’s why they say they don’t talk with somebody.
They need some type of open-door anticipatory guidance as a way forward. Not everyone is comfortable directly asking whether a patient is engaging in this, but at least letting people know that you’ve heard of this behavior and providing some medical facts can give us a step forward with creating these conversations.
Dr. Rubin: Can you tell us where is this research going in terms of next steps? Other things that you’re looking at? And what are you excited about?
Dr. Herbenick: I’m excited about some work I did with a collaborator and colleague of mine, Dr. Keisuke Kawata, that he led a couple of years ago. He’s a neuroscientist. We were looking at potential cumulative effects on the brain. Now we’re taking some of that research into its next steps. We’re also doing more focused studies on other health consequences and hopefully finding out how we can test different educational messages and get people to learn more fact-based information about this, and then see if that is effective in prevention.
Dr. Rubin: It sounds like a public health campaign is really needed about how to get the word out there about the health consequences of these activities. We’re asking people often enough. In my clinic, I try to keep it open-ended — tell me what sex looks like. What does it look like, and what do you want it to look like? Because I see a lot of people with problems, but if they don’t bring it to me, I don’t necessarily bring it up to them. Until I heard your lecture, and I thought, oh my gosh, I’m not even asking the right questions. Are you hopeful that there will be more public health messaging out there?
Dr. Herbenick: I am. Years ago, when the child and adolescent choking game became a thing, the Centers for Disease Control and Prevention (CDC) issued reports about it and warnings to parents. And this is a far, far higher prevalence than that ever was. So, I would love to see organizations like the CDC and medical groups getting involved and educating their members and making statements. This is really impacting a huge generation of girls and women, because when it happens during sex between women and men, the choking is mostly happening to the girls and women. It’s also prevalent among sexual minority individuals. But we are talking about this whole generation of young women and what’s happening to their bodies and their brain health. We really need to step into this conversation.
Dr. Rubin: Very few of us are sexual medicine–trained physicians, and very few of us feel confident and comfortable talking about sexual health issues. But people are getting hurt. People are having real consequences of these behaviors because of our lack of education, knowledge, and even discussion around it.

Atogepant May Prevent Rebound Headache From Medication Overuse in Chronic Migraine
The oral calcitonin gene-related peptide receptor antagonist atogepant is effective in preventing rebound headache related to medication overuse in patients with chronic migraine (CM), new research suggested.
Results of a subgroup analysis of a phase 3, 12-week randomized, double-blind, placebo-controlled trial showed up to a 62% reduction in the proportion of atogepant-treated participants who met acute medication overuse criteria.
“Based on our findings, treatment with atogepant may potentially decrease the risk of developing rebound headache by reducing the use of pain medications,” principal investigator Peter Goadsby, MD, PhD, of King’s College London, London, England, said in a news release.
The study was published online in Neurology.
Effective Prevention Needed
Acute treatments for migraine can mitigate symptoms and reduce disability but can also be ineffective and even result in increased dosing and overuse of these medications, the investigators noted.
Acute medication overuse is defined as “taking simple analgesics for ≥ 15 days per month or taking triptans, ergots, opioids, or combinations of medications for ≥ 10 days per month.”
“There is a high prevalence of pain medication overuse among people with migraine as they try to manage what are often debilitating symptoms,” Dr. Goadsby said. “However, medication overuse can lead to more headaches, called rebound headaches, so more effective preventive treatments are needed.”
Atogepant was developed for migraine prevention in adults. It had been studied in the phase 3 PROGRESS trial, which showed it significantly reduced monthly migraine days (MMDs) compared with placebo during the 12-week trial.
The new subgroup analysis of the study focused specifically on the efficacy and safety of atogepant vs placebo in participants with CM with, and without, medication overuse.
Participants (mean age, 42.1 years; 87.6% women) were randomized to receive either atogepant 30 mg twice daily (n = 253), atogepant 60 mg once daily (n = 256), or placebo (n = 240), with baseline demographics and clinical characteristics similar across all treatment arms. A total of 66.2% met baseline acute medication overuse criteria.
Participants were asked to record migraine and headache experiences in an electronic diary.
‘Effective and Safe’
Participants in both atogepant groups experienced fewer monthly headache days (MHDs) than those in the placebo group, with a least squares mean difference (LSMD) of −2.7 (95% confidence interval [CI], −4.0 to −1.4) in the atogepant 30 mg twice daily group and −1.9 (95% CI, −3.2 to −0.6) in the atogepant 60 mg once daily group.
MHDs were also reduced in both treatment groups, with LSMDs of −2.8 (95% CI, −4.0 to −1.5) and −2.1 (95% CI, −3.3 to −0.8), respectively. Mean acute medication use days were lower in both the treatment groups, with LSMDs of −2.8 (95% CI, −4.1 to −1.6) and −2.6 (95% CI, −3.9 to −1.3), respectively.
A higher proportion of participants achieved a ≥ 50% reduction in MMDs with atogepant 30 mg twice daily (odds ratio [OR], 2.5; 95% CI, 1.5-4.0) and atogepant 60 mg once daily (OR, 2.3; 95% CI, 1.4-3.7).
Notably, the researchers found a 52.1%-61.9% reduction in the proportion of atogepant-treated participants meeting acute medication overuse criteria during the study period vs 38.3% in the placebo group.
Similar results were observed in the subgroup without acute medication overuse.
Treatment-emergent adverse events were reported by 55.8% of participants treated with atogepant 30 mg twice daily, 66.1% with atogepant 60 mg once daily, and 48.5% with placebo in the acute medication overuse subgroup, with similar reports in the non-overuse subgroup.
A limitation cited by the authors was that participants’ self-report of migraines and headaches via electronic diaries might have been inaccurate.
Nevertheless, they concluded that the results showed atogepant to be an “effective and safe” preventive treatment for patients with CM with, and without, acute medication overuse.

FROM NEUROLOGY
Treatable Condition Misdiagnosed as Dementia in Almost 13% of Cases
The study of more than 68,000 individuals in the general population diagnosed with dementia between 2009 and 2019 found that almost 13% had FIB-4 scores indicative of cirrhosis and potential hepatic encephalopathy.
The findings, recently published online in The American Journal of Medicine, corroborate and extend the researchers’ previous work, which showed that about 10% of US veterans with a dementia diagnosis may in fact have hepatic encephalopathy.
“We need to increase awareness that cirrhosis and related brain complications are common, silent, but treatable when found,” said corresponding author Jasmohan Bajaj, MD, of Virginia Commonwealth University and Richmond VA Medical Center, Richmond, Virginia. “Moreover, these are being increasingly diagnosed in older individuals.”
“Cirrhosis can also predispose patients to liver cancer and other complications, so diagnosing it in all patients is important, regardless of the hepatic encephalopathy-dementia connection,” he said.
FIB-4 Is Key
Dr. Bajaj and colleagues analyzed data from 72 healthcare centers on 68,807 nonveteran patients diagnosed with dementia at two or more physician visits between 2009 and 2019. Patients had no prior cirrhosis diagnosis, the mean age was 73 years, 44.7% were men, and 78% were White.
The team measured the prevalence of two high FIB-4 scores (> 2.67 and > 3.25), selected for their strong predictive value for advanced cirrhosis. Researchers also examined associations between high scores and multiple comorbidities and demographic factors.
Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and platelet labs were collected up to 2 years after the index dementia diagnosis because they are used to calculate FIB-4.
The mean FIB-4 score was 1.78, mean ALT was 23.72 U/L, mean AST was 27.42 U/L, and mean platelets were 243.51 × 109/µL.
A total of 8683 participants (12.8%) had a FIB-4 score greater than 2.67 and 5185 (7.6%) had a score greater than 3.25.
In multivariable logistic regression models, FIB-4 greater than 3.25 was associated with viral hepatitis (odds ratio [OR], 2.23), congestive heart failure (OR,1.73), HIV (OR, 1.72), male gender (OR, 1.42), alcohol use disorder (OR, 1.39), and chronic kidney disease (OR, 1.38).
FIB-4 greater than 3.25 was inversely associated with White race (OR, 0.76) and diabetes (OR, 0.82).
The associations were similar when using a threshold score of greater than 2.67.
“With the aging population, including those with cirrhosis, the potential for overlap between hepatic encephalopathy and dementia has risen and should be considered in the differential diagnosis,” the authors wrote. “Undiagnosed cirrhosis and potential hepatic encephalopathy can be a treatable cause of or contributor towards cognitive impairment in patients diagnosed with dementia.”
Providers should use the FIB-4 index as a screening tool to detect cirrhosis in patients with dementia, they concluded.
The team’s next steps will include investigating barriers to the use of FIB-4 among practitioners, Dr. Bajaj said.
Incorporating use of the FIB-4 index into screening guidelines “with input from all stakeholders, including geriatricians, primary care providers, and neurologists … would greatly expand the diagnosis of cirrhosis and potentially hepatic encephalopathy in dementia patients,” Dr. Bajaj said.
The study had a few limitations, including the selected centers in the cohort database, lack of chart review to confirm diagnoses in individual cases, and the use of a modified FIB-4, with age capped at 65 years.
‘Easy to Miss’
Commenting on the research, Nancy Reau, MD, section chief of hepatology at Rush University Medical Center in Chicago, said that it is easy for physicians to miss asymptomatic liver disease that could progress and lead to cognitive decline.
“Most of my patients are already labeled with liver disease; however, it is not uncommon to receive a patient from another specialist who felt their presentation was more consistent with liver disease than the issue they were referred for,” she said.
Still, even in metabolic dysfunction–associated steatotic liver disease, which affects nearly one third of the population, the condition isn’t advanced enough in most patients to cause symptoms similar to those of dementia, said Dr. Reau, who was not associated with the study.
“It is more important for specialists in neurology to exclude liver disease and for hepatologists or gastroenterologists to be equipped with tools to exclude alternative explanations for neurocognitive presentations,” she said. “It is important to not label a patient as having HE and then miss alternative explanations.”
“Every presentation has a differential diagnosis. Using easy tools like FIB-4 can make sure you don’t miss liver disease as a contributing factor in a patient that presents with neurocognitive symptoms,” Dr. Reau said.
This work was partly supported by grants from Department of Veterans Affairs merit review program and the National Institutes of Health’s National Center for Advancing Translational Science. Dr. Bajaj and Dr. Reau reported no conflicts of interest.

The study of more than 68,000 individuals in the general population diagnosed with dementia between 2009 and 2019 found that almost 13% had FIB-4 scores indicative of cirrhosis and potential hepatic encephalopathy.
The findings, recently published online in The American Journal of Medicine, corroborate and extend the researchers’ previous work, which showed that about 10% of US veterans with a dementia diagnosis may in fact have hepatic encephalopathy.
“We need to increase awareness that cirrhosis and related brain complications are common, silent, but treatable when found,” said corresponding author Jasmohan Bajaj, MD, of Virginia Commonwealth University and Richmond VA Medical Center, Richmond, Virginia. “Moreover, these are being increasingly diagnosed in older individuals.”
“Cirrhosis can also predispose patients to liver cancer and other complications, so diagnosing it in all patients is important, regardless of the hepatic encephalopathy-dementia connection,” he said.

Greater Transparency of Oncologists’ Pharma Relationships Needed
The findings reflect limited awareness in low-income countries about what scenarios constitute a conflict of interest, first author, Khalid El Bairi, MD, said during an interview. “There is a lack of training in ethics and integrity in medical schools [in countries in Africa], so people are not informed about conflicts of interest,” continued Dr. El Bairi, who presented the new research at the annual meeting of the American Society of Clinical Oncology. “There is also a lack of policies in universities and hospitals to guide clinicians about conflict of interest reporting.”
Overall, 58.5% of survey participants categorized honoraria as a conflict of interest that required disclosure, while 50% said the same of gifts from pharmaceutical representatives, and 44.5% identified travel grants for attending conferences as conflicts of interests. The report was published in JCO Global Oncology. Less often considered conflicts of interest were personal and institutional research funding, trips to conferences, consulting or advisory roles, food and beverages, expert testimony, and sample drugs provided by the pharmaceutical industry.
Just 24% of participants indicated that all of the listed items were deemed conflicts of interest. The survey — called Oncology Transparency Under Scrutiny and Tracking, or ONCOTRUST-1 — considered the perceptions of 200 oncologists, about 70% of whom practice in low- and middle-income countries.
What’s more, 37.5% of respondents identified fear of losing financial support as a reason not to report a conflict of interest. Still, 75% indicated that industry-sponsored speaking does not affect treatment decisions, and 60% said conflicts of interest do not impair objective appraisal of clinical trials.
Dr. El Bairi, a research associate in the department of medical oncology at Mohammed VI University Hospital, Oujda, Morocco, and his colleagues undertook the study in part because of an editorial published in The Lancet Oncology last year. First author Fidel Rubagumya, MD, a consultant oncologist and director of research at Rwanda Military Hospital, Kigali, and colleagues called for more research on the ties between oncologists and industry in Africa. The ONCOTRUST-1 findings set the stage for a planned follow-up study, which aims to compare views surrounding conflicts of interests between oncologists in different economic settings.
Open Payments Houses US Physicians’ Conflicts of Interest
To be sure, many authors of research published in major US journals are based outside of the United States. According to JAMA Network Open, 69% of submissions to the journal are from international authors. However, Dr. El Bairi also raised other potential signs of industry influence that he said need global discussion, such as the role of pharmaceutical companies in presentations of clinical trial findings at large cancer societies’ conferences, a shift toward progression-free survival as the endpoint in clinical cancer trials, and the rise of third-party writing assistance.
“There are two sides of the story,” Dr. El Bairi said. “The good side is that unfortunately, sometimes [industry money is] the only way for African oncologists to go abroad for training, to conferences for their continuous medical education. The bad is now we may harm patients, we might harm science by having conflicts of interest not reported.”
Unlike other countries, the United States has plentiful data on the scale of physicians’ financial conflicts of interest in the form of the Open Payments platform. Championed by Sen. Chuck Grassley (R-Iowa), the federal repository of payments to doctors and teaching hospitals by drug and medical device companies was established as part of the Affordable Care Act (ACA).
The health care reform law, which passed in 2010, requires pharmaceutical companies and medical device makers to report this information.
From 2013 to 2021, the pharmaceutical and medical device industry paid physicians $12.1 billion, according to a research letter published in JAMA in March of 2024 that reviewed Open Payments data.
Ranked by specialty, hematologists and oncologists received the fourth-largest amount of money in aggregate, the study shows. Their total of $825.8 million trailed only physicians in orthopedics ($1.36 billion), neurology and psychiatry ($1.32 billion) and cardiology ($1.29 billion). What’s more, this specialty had the biggest share of physicians taking industry money, with 74.2% of hematologists and oncologists receiving payments.
The payments from industry include fees for consulting services and speaking, as well as food and beverages, travel and lodging, education, gifts, grants, and honoraria.
Joseph S. Ross, MD, MHS, one of the JAMA study’s coauthors, said in an interview that the continued prevalence of such funding runs counter to the expectation behind the measure, which was that transparency would lead to physicians’ becoming less likely to accept a payment.
“We as a profession need to take a cold hard look in the mirror,” he said, referring to physicians in general.
Dr. Ross, professor of medicine at Yale University School of Medicine, New Haven, Connecticut, said he hopes that the profession will self-police, and that patients will make a bigger deal of the issue. Still, he acknowledged that “the vast majority” of patient advocacy groups, too, are funded by the pharmaceutical industry.
Exposing Industry Payments May Have Perverse Effect
A growing body of research explores the effect that physicians’ financial relationships with pharmaceutical companies can have on their prescribing practices. Indeed, oncologists taking industry payments seem to be more likely to prescribe nonrecommended and low-value drugs in some clinical settings, according to a study published in The BMJ last year.
That study’s first author, Aaron P. Mitchell, MD, a medical oncologist and assistant attending physician at Memorial Sloan Kettering Cancer Center, New York City, suggested in an interview that exposing industry payments to the sunlight may have had a perverse effect on physicians.
“There’s this idea of having license to do something,” Dr. Mitchell said, speaking broadly about human psychology rather than drawing on empirical data. “You might feel a little less bad about then prescribing more of that company’s drug, because the disclosure has already been done.”
The influence of pharmaceutical industry money on oncologists goes beyond what’s prescribed to which treatments get studied, approved, and recommended by guidelines, Dr. Mitchell said. He was also first author of a 2016 paper published in JAMA Oncology that found 86% of authors of the National Comprehensive Cancer Network guidelines had at least one conflict of interest reported on Open Systems in 2014.
Meanwhile, the fact that physicians’ payments from industry are a matter of public record on Open Systems has not guaranteed that doctors will disclose their conflicts of interest in other forums. A study published in JAMA earlier this year, for which Dr. Mitchell served as first author, found that almost one in three physicians endorsing drugs and devices on the social media platform X failed to disclose that the manufacturer paid them.
The lack of disclosure seems to extend beyond social media. A 2018 study published in JAMA Oncology found that 32% of oncologist authors of clinical drug trials for drugs approved over a 20-month period from 2016 to 2017 did not fully disclose payments from the trial sponsor when checked against the Open Payments database.
A lion’s share of industry payments within oncology appears to be going to a small group of high-profile physicians, suggested a 2022 study published in JCO Oncology Practice. It found that just 1% of all US oncologists accounted for 37% of industry payments, with each receiving more than $100,000 a year.
Experts: Professional Societies Should Further Limit Industry Payments
While partnerships between drug companies and physicians are necessary and have often been positive, more than disclosure is needed to minimize the risk of patient harm, according to an editorial published in March in JCO Oncology Practice. In it, Nina Niu Sanford, MD, a radiation oncologist UT Southwestern Medical Center, Dallas, and Bishal Gyawali, MD, PhD, a medical oncologist at Queen’s University, Kingston, Ontario, Canada, argue that following a specific blueprint could help mitigate financial conflicts of interest.
For starters, Dr. Sanford and Dr. Gyawali contend in the editorial that the maximum general payment NCCN members are allowed to receive from industry should be $0, compared with a current bar of $20,000 from a single entity or $50,000 from all external entities combined. They also urge professional societies to follow the current policy of the American Society of Clinical Oncology and ban members serving in their leadership from receiving any general payments from the industry.
The authors further suggest that investigators of clinical trials should be barred from holding stock for the drug or product while it is under study and that editorialists should not have conflicts of interest with the company whose drug or product they are discussing.
Pharmaceutical money can harm patients in ways that are not always obvious, Dr. Gyawali said in an interview.
“It can dominate the conversation by removing critical viewpoints from these top people about certain drugs,” he said. “It’s not always about saying good things about the drug.”
For instance, he suggested, a doctor receiving payments from Pfizer might openly criticize perceived flaws in drugs from other companies but refrain from weighing in negatively on a Pfizer drug.
From 2016 to 2018, industry made general payments to more than 52,000 physicians for 137 unique cancer drugs, according to a separate 2021 study published in the Journal of Cancer Policy, for which Dr. Gyawali served as one of the coauthors.
The results suggest that pharmaceutical money affects the entire cancer system, not relatively few oncology leaders. The amounts and dollar values grew each year covered by the study, to nearly 466,000 payments totaling $98.5 million in 2018.
Adriane Fugh-Berman, MD, professor of pharmacology and physiology at Georgetown University, Washington, DC, and director of PharmedOut, a Georgetown-based project that advances evidence-based prescribing and educates healthcare professionals about pharmaceutical marketing practices, has called for a ban on industry gifts to physicians.
When a publication asks physicians to disclose relevant conflicts of interest, physicians may choose not to disclose, because they don’t feel that their conflicts are relevant, Dr. Fugh-Berman said. Drug and device makers have also grown sophisticated about how they work with physicians, she suggested. “It’s illegal to market a drug before it comes on the market, but it’s not illegal to market the disease,” said Dr. Fugh-Berman, noting that drugmakers often work on long timelines.
“The doctor is going around saying we don’t have good therapies. They’re not pushing a drug. And so they feel totally fine about it.”
Anecdotally, Dr. Fugh-Berman noted that, if anything, speaking fees and similar payments only improve doctors’ reputations. She said that’s especially true if the physicians are paid by multiple companies, on the supposed theory that their conflicts of interest cancel each other out.
“I’m not defending this,” added Dr. Fugh-Berman, observing that, at the end of the day, such conflicts may go against the interests of patients.
“Sometimes the best drugs are older, generic, cheap drugs, and if oncologists or other specialists are only choosing among the most promoted drugs, they’re not necessarily choosing the best drugs.”
Beyond any prestige, doctors have other possible nonfinancial incentives for receiving industry payments. “It’s the relationships,” Dr. Fugh-Berman said. “Companies are very good at offering friendship.”
Dr. El Bairi reported NCODA leadership and honoraria along with expert testimony through techspert.io. Dr. Ross reported that he is a deputy editor of JAMA but was not involved in decisions regarding acceptance of or the review of the manuscript he authored and discussed in this article. Dr. Ross also reported receiving grants from the Food and Drug Administration, Johnson & Johnson, the Medical Device Innovation Consortium, the Agency for Healthcare Research and Quality, and the National Heart, Lung, and Blood Institute. He was an expert witness in a qui tam suit alleging violations of the False Claims Act and Anti-Kickback Statute against Biogen that was settled in 2022. Dr. Mitchell reported no relevant financial relationships. Dr. Gyawali reported a consulting or advisory role with Vivio Health. Dr. Fugh-Berman reported being an expert witness for plaintiffs in complaints about drug and device marketing practices.
The findings reflect limited awareness in low-income countries about what scenarios constitute a conflict of interest, first author, Khalid El Bairi, MD, said during an interview. “There is a lack of training in ethics and integrity in medical schools [in countries in Africa], so people are not informed about conflicts of interest,” continued Dr. El Bairi, who presented the new research at the annual meeting of the American Society of Clinical Oncology. “There is also a lack of policies in universities and hospitals to guide clinicians about conflict of interest reporting.”

For instance, he suggested, a doctor receiving payments from Pfizer might openly criticize perceived flaws in drugs from other companies but refrain from weighing in negatively on a Pfizer drug.
From 2016 to 2018, industry made general payments to more than 52,000 physicians for 137 unique cancer drugs, according to a separate 2021 study published in the Journal of Cancer Policy, for which Dr. Gyawali served as one of the coauthors.
The results suggest that pharmaceutical money affects the entire cancer system, not relatively few oncology leaders. The amounts and dollar values grew each year covered by the study, to nearly 466,000 payments totaling $98.5 million in 2018.
Adriane Fugh-Berman, MD, professor of pharmacology and physiology at Georgetown University, Washington, DC, and director of PharmedOut, a Georgetown-based project that advances evidence-based prescribing and educates healthcare professionals about pharmaceutical marketing practices, has called for a ban on industry gifts to physicians.
When a publication asks physicians to disclose relevant conflicts of interest, physicians may choose not to disclose, because they don’t feel that their conflicts are relevant, Dr. Fugh-Berman said. Drug and device makers have also grown sophisticated about how they work with physicians, she suggested. “It’s illegal to market a drug before it comes on the market, but it’s not illegal to market the disease,” said Dr. Fugh-Berman, noting that drugmakers often work on long timelines.
“The doctor is going around saying we don’t have good therapies. They’re not pushing a drug. And so they feel totally fine about it.”
Anecdotally, Dr. Fugh-Berman noted that, if anything, speaking fees and similar payments only improve doctors’ reputations. She said that’s especially true if the physicians are paid by multiple companies, on the supposed theory that their conflicts of interest cancel each other out.
“I’m not defending this,” added Dr. Fugh-Berman, observing that, at the end of the day, such conflicts may go against the interests of patients.
“Sometimes the best drugs are older, generic, cheap drugs, and if oncologists or other specialists are only choosing among the most promoted drugs, they’re not necessarily choosing the best drugs.”
Beyond any prestige, doctors have other possible nonfinancial incentives for receiving industry payments. “It’s the relationships,” Dr. Fugh-Berman said. “Companies are very good at offering friendship.”
Dr. El Bairi reported NCODA leadership and honoraria along with expert testimony through techspert.io. Dr. Ross reported that he is a deputy editor of JAMA but was not involved in decisions regarding acceptance of or the review of the manuscript he authored and discussed in this article. Dr. Ross also reported receiving grants from the Food and Drug Administration, Johnson & Johnson, the Medical Device Innovation Consortium, the Agency for Healthcare Research and Quality, and the National Heart, Lung, and Blood Institute. He was an expert witness in a qui tam suit alleging violations of the False Claims Act and Anti-Kickback Statute against Biogen that was settled in 2022. Dr. Mitchell reported no relevant financial relationships. Dr. Gyawali reported a consulting or advisory role with Vivio Health. Dr. Fugh-Berman reported being an expert witness for plaintiffs in complaints about drug and device marketing practices.
The findings reflect limited awareness in low-income countries about what scenarios constitute a conflict of interest, first author, Khalid El Bairi, MD, said during an interview. “There is a lack of training in ethics and integrity in medical schools [in countries in Africa], so people are not informed about conflicts of interest,” continued Dr. El Bairi, who presented the new research at the annual meeting of the American Society of Clinical Oncology. “There is also a lack of policies in universities and hospitals to guide clinicians about conflict of interest reporting.”
Overall, 58.5% of survey participants categorized honoraria as a conflict of interest that required disclosure, while 50% said the same of gifts from pharmaceutical representatives, and 44.5% identified travel grants for attending conferences as conflicts of interests. The report was published in JCO Global Oncology. Less often considered conflicts of interest were personal and institutional research funding, trips to conferences, consulting or advisory roles, food and beverages, expert testimony, and sample drugs provided by the pharmaceutical industry.
Just 24% of participants indicated that all of the listed items were deemed conflicts of interest. The survey — called Oncology Transparency Under Scrutiny and Tracking, or ONCOTRUST-1 — considered the perceptions of 200 oncologists, about 70% of whom practice in low- and middle-income countries.
What’s more, 37.5% of respondents identified fear of losing financial support as a reason not to report a conflict of interest. Still, 75% indicated that industry-sponsored speaking does not affect treatment decisions, and 60% said conflicts of interest do not impair objective appraisal of clinical trials.
Dr. El Bairi, a research associate in the department of medical oncology at Mohammed VI University Hospital, Oujda, Morocco, and his colleagues undertook the study in part because of an editorial published in The Lancet Oncology last year. First author Fidel Rubagumya, MD, a consultant oncologist and director of research at Rwanda Military Hospital, Kigali, and colleagues called for more research on the ties between oncologists and industry in Africa. The ONCOTRUST-1 findings set the stage for a planned follow-up study, which aims to compare views surrounding conflicts of interests between oncologists in different economic settings.
Open Payments Houses US Physicians’ Conflicts of Interest
To be sure, many authors of research published in major US journals are based outside of the United States. According to JAMA Network Open, 69% of submissions to the journal are from international authors. However, Dr. El Bairi also raised other potential signs of industry influence that he said need global discussion, such as the role of pharmaceutical companies in presentations of clinical trial findings at large cancer societies’ conferences, a shift toward progression-free survival as the endpoint in clinical cancer trials, and the rise of third-party writing assistance.
“There are two sides of the story,” Dr. El Bairi said. “The good side is that unfortunately, sometimes [industry money is] the only way for African oncologists to go abroad for training, to conferences for their continuous medical education. The bad is now we may harm patients, we might harm science by having conflicts of interest not reported.”
Unlike other countries, the United States has plentiful data on the scale of physicians’ financial conflicts of interest in the form of the Open Payments platform. Championed by Sen. Chuck Grassley (R-Iowa), the federal repository of payments to doctors and teaching hospitals by drug and medical device companies was established as part of the Affordable Care Act (ACA).
The health care reform law, which passed in 2010, requires pharmaceutical companies and medical device makers to report this information.
From 2013 to 2021, the pharmaceutical and medical device industry paid physicians $12.1 billion, according to a research letter published in JAMA in March of 2024 that reviewed Open Payments data.
Ranked by specialty, hematologists and oncologists received the fourth-largest amount of money in aggregate, the study shows. Their total of $825.8 million trailed only physicians in orthopedics ($1.36 billion), neurology and psychiatry ($1.32 billion) and cardiology ($1.29 billion). What’s more, this specialty had the biggest share of physicians taking industry money, with 74.2% of hematologists and oncologists receiving payments.
The payments from industry include fees for consulting services and speaking, as well as food and beverages, travel and lodging, education, gifts, grants, and honoraria.
Joseph S. Ross, MD, MHS, one of the JAMA study’s coauthors, said in an interview that the continued prevalence of such funding runs counter to the expectation behind the measure, which was that transparency would lead to physicians’ becoming less likely to accept a payment.
“We as a profession need to take a cold hard look in the mirror,” he said, referring to physicians in general.
Dr. Ross, professor of medicine at Yale University School of Medicine, New Haven, Connecticut, said he hopes that the profession will self-police, and that patients will make a bigger deal of the issue. Still, he acknowledged that “the vast majority” of patient advocacy groups, too, are funded by the pharmaceutical industry.
Exposing Industry Payments May Have Perverse Effect
A growing body of research explores the effect that physicians’ financial relationships with pharmaceutical companies can have on their prescribing practices. Indeed, oncologists taking industry payments seem to be more likely to prescribe nonrecommended and low-value drugs in some clinical settings, according to a study published in The BMJ last year.
That study’s first author, Aaron P. Mitchell, MD, a medical oncologist and assistant attending physician at Memorial Sloan Kettering Cancer Center, New York City, suggested in an interview that exposing industry payments to the sunlight may have had a perverse effect on physicians.
“There’s this idea of having license to do something,” Dr. Mitchell said, speaking broadly about human psychology rather than drawing on empirical data. “You might feel a little less bad about then prescribing more of that company’s drug, because the disclosure has already been done.”
The influence of pharmaceutical industry money on oncologists goes beyond what’s prescribed to which treatments get studied, approved, and recommended by guidelines, Dr. Mitchell said. He was also first author of a 2016 paper published in JAMA Oncology that found 86% of authors of the National Comprehensive Cancer Network guidelines had at least one conflict of interest reported on Open Systems in 2014.
Meanwhile, the fact that physicians’ payments from industry are a matter of public record on Open Systems has not guaranteed that doctors will disclose their conflicts of interest in other forums. A study published in JAMA earlier this year, for which Dr. Mitchell served as first author, found that almost one in three physicians endorsing drugs and devices on the social media platform X failed to disclose that the manufacturer paid them.
The lack of disclosure seems to extend beyond social media. A 2018 study published in JAMA Oncology found that 32% of oncologist authors of clinical drug trials for drugs approved over a 20-month period from 2016 to 2017 did not fully disclose payments from the trial sponsor when checked against the Open Payments database.
A lion’s share of industry payments within oncology appears to be going to a small group of high-profile physicians, suggested a 2022 study published in JCO Oncology Practice. It found that just 1% of all US oncologists accounted for 37% of industry payments, with each receiving more than $100,000 a year.
Experts: Professional Societies Should Further Limit Industry Payments
While partnerships between drug companies and physicians are necessary and have often been positive, more than disclosure is needed to minimize the risk of patient harm, according to an editorial published in March in JCO Oncology Practice. In it, Nina Niu Sanford, MD, a radiation oncologist UT Southwestern Medical Center, Dallas, and Bishal Gyawali, MD, PhD, a medical oncologist at Queen’s University, Kingston, Ontario, Canada, argue that following a specific blueprint could help mitigate financial conflicts of interest.
For starters, Dr. Sanford and Dr. Gyawali contend in the editorial that the maximum general payment NCCN members are allowed to receive from industry should be $0, compared with a current bar of $20,000 from a single entity or $50,000 from all external entities combined. They also urge professional societies to follow the current policy of the American Society of Clinical Oncology and ban members serving in their leadership from receiving any general payments from the industry.
The authors further suggest that investigators of clinical trials should be barred from holding stock for the drug or product while it is under study and that editorialists should not have conflicts of interest with the company whose drug or product they are discussing.
Pharmaceutical money can harm patients in ways that are not always obvious, Dr. Gyawali said in an interview.
“It can dominate the conversation by removing critical viewpoints from these top people about certain drugs,” he said. “It’s not always about saying good things about the drug.”
