Diabetes Drug Improved Symptoms in Small Study of Women With Central Centrifugal Cicatricial Alopecia
TOPLINE:
in a retrospective case series.
METHODOLOGY:
- Researchers conducted a case series involving 12 Black women in their 30s, 40s, and 50s, with biopsy-confirmed, treatment-refractory CCCA, a chronic inflammatory hair disorder characterized by permanent hair loss, from the Johns Hopkins University alopecia clinic.
- Participants received CCCA treatment for at least 6 months and had stagnant or worsening symptoms before oral extended-release metformin (500 mg daily) was added to treatment. (Treatments included topical clobetasol, compounded minoxidil, and platelet-rich plasma injections.)
- Scalp biopsies were collected from four patients before and after metformin treatment to evaluate gene expression changes.
- Changes in clinical symptoms were assessed, including pruritus, inflammation, pain, scalp resistance, and hair regrowth, following initiation of metformin treatment.
TAKEAWAY:
- Metformin led to significant clinical improvement in eight patients, which included reductions in scalp pain, scalp resistance, pruritus, and inflammation. However, two patients experienced worsening symptoms.
- Six patients showed clinical evidence of hair regrowth after at least 6 months of metformin treatment with one experiencing hair loss again 3 months after discontinuing treatment.
- Transcriptomic analysis revealed 34 up-regulated genes, which included up-regulated of 23 hair keratin–associated proteins, and pathways related to keratinization, epidermis development, and the hair cycle. In addition, eight genes were down-regulated, with pathways that included those associated with extracellular matrix organization, collagen fibril organization, and collagen metabolism.
- Gene set variation analysis showed reduced expression of T helper 17 cell and epithelial-mesenchymal transition pathways and elevated adenosine monophosphate kinase signaling and keratin-associated proteins after treatment with metformin.
IN PRACTICE:
“Metformin’s ability to concomitantly target fibrosis and inflammation provides a plausible mechanism for its therapeutic effects in CCCA and other fibrosing alopecia disorders,” the authors concluded. But, they added, “larger prospective, placebo-controlled randomized clinical trials are needed to rigorously evaluate metformin’s efficacy and optimal dosing for treatment of cicatricial alopecias.”
SOURCE:
The study was led by Aaron Bao, Department of Dermatology, Johns Hopkins University School of Medicine, Baltimore, Maryland, and was published online on September 4 in JAMA Dermatology.
LIMITATIONS:
A small sample size, retrospective design, lack of a placebo control group, and the single-center setting limited the generalizability of the study findings. Additionally, the absence of a validated activity or severity scale for CCCA and the single posttreatment sampling limit the assessment and comparison of clinical symptoms and transcriptomic changes.
DISCLOSURES:
The study was supported by the American Academy of Dermatology. One author reported several ties with pharmaceutical companies, a pending patent, and authorship for the UpToDate section on CCCA.

Short Steroid Treatment May Raise Diabetes Risk: Study
People who received systemic glucocorticoids during short hospital stays were more than twice as likely to develop new onset diabetes than those who didn’t, reported the authors of a large study that analyzed more than a decade’s worth of patient records.
Rajna Golubic, MD, PhD, of the diabetes trials unit at the University of Oxford, United Kingdom, and colleagues did an observational cohort study, using data from electronic healthcare records of more than patients admitted between January 1, 2013, and October 1, 2023.
They looked for patients who didn’t have a diabetes diagnosis at the time of admission and who were not taking a steroid. Their research was presented this month at the 2024 annual meeting of the European Association for the Study of Diabetes (EASD) in Madrid, Spain.
About 1.8%, of 316, of the 17,258 patients who received systemic glucocorticoids (tablets, injections, or infusions) during their hospital stay developed new-onset diabetes, while this happened to only 0.8%, or 3450, of the 434,348 who did not get these drugs, according to an abstract of the EASD presentation.
The median length of stay was 3 days (2-8) for the group of patients who took steroids, compared with 1 day (1-3) in those who did not. Further analysis showed that, when age and sex were factored in, patients receiving systemic glucocorticoids were more than twice as likely (2.6 times) to develop diabetes as those not receiving the treatment, Dr. Golubic said.
This research builds on previous studies that looked at smaller groups of patients and the diabetes risk in patients with specific conditions, including rheumatoid arthritis, Dr. Golubic said. It may prove helpful for clinicians considering when to employ steroids, which are useful medications for managing inflammation associated with many conditions.
“This gives them a very good estimate of how much more likely people treated with systemic glucocorticoids are to develop new-onset diabetes,” Dr. Golubic said.
Glucocorticoids have for decades been used for managing acute and chronic inflammatory diseases. The link to diabetes has been previously reported in smaller studies and in ones linked to specific conditions such as respiratory disease and rheumatoid arthritis.
Carolyn Cummins, PhD, an associate professor at the University of Toronto, Canada, who was not part of this study, told this news organization she was pleased to see a study of diabetes and steroids done with the scope that Dr. Golubic and colleagues undertook. Dr. Cummins in 2022 published an article titled “Fresh insights into glucocorticoid-induced diabetes mellitus and new therapeutic directions” in Nature Reviews Endocrinology.
“We know that this is an issue, but we didn’t necessarily know numerically how significant it was,” Dr. Cummins said. “I would say it wasn’t a surprising finding, but it’s nice to actually have the numbers from a large study.”
Dr. Golubic and Dr. Cummins reported no relevant financial relationships.

FROM EASD 2024
Will New Obesity Drugs Make Bariatric Surgery Obsolete?
MADRID — In spirited presentations at the annual meeting of the European Association for the Study of Diabetes, Louis J. Aronne, MD, of Weill Cornell Medicine in New York City, made a compelling case that the next generation of obesity medications will make bariatric surgery obsolete, and Francesco Rubino, MD, of King’s College London in England, made an equally compelling case that they will not.
In fact, Dr. Rubino predicted that “metabolic” surgery — new nomenclature reflecting the power of surgery to reduce not only obesity, but also other metabolic conditions, over the long term — will continue and could even increase in years to come.
‘Medical Treatment Will Dominate’
“Obesity treatment is the superhero of treating metabolic disease because it can defeat all of the bad guys at once, not just one, like the other treatments,” Dr. Aronne told meeting attendees. “If you treat somebody’s cholesterol, you’re just treating their cholesterol, and you may actually increase their risk of developing type 2 diabetes (T2D). You treat their blood pressure, you don’t treat their glucose and you don’t treat their lipids — the list goes on and on and on. But by treating obesity, if you can get enough weight loss, you can get all those things at once.”
He pointed to the SELECT trial, which showed that treating obesity with a glucagon-like peptide 1 receptor agonist reduced major adverse cardiovascular events as well as death from any cause, results in line with those from other modes of treatment for cardiovascular disease (CVD) or lipid lowering, he said. “But we get much more with these drugs, including positive effects on heart failure, chronic kidney disease, and a 73% reduction in T2D. So, we’re now on the verge of a major change in the way we manage metabolic disease.”
Dr. Aronne drew a parallel between treating obesity and the historic way of treating hypertension. Years ago, he said, “we waited too long to treat people. We waited until they had severe hypertension that in many cases was irreversible. What would you prefer to do now for obesity — have the patient lose weight with a medicine that is proven to reduce complications or wait until they develop diabetes, high blood pressure, heart disease and then have them undergo surgery to treat that?”
Looking ahead, “the trend could be to treat obesity before it gets out of hand,” he suggested. Treatment might start in people with a body mass index (BMI) of 27 kg/m2, who would be treated to a target BMI of 25. “That’s only a 10% or so change, but our goal would be to keep them in the normal range so they never go above that target. In fact, I think we’re going to be looking at people with severe obesity in a few years and saying, ‘I can’t believe someone didn’t treat that guy earlier.’ What’s going to happen to bariatric surgery if no one gets to a higher weight?”
The plethora of current weight-loss drugs and the large group on the horizon mean that if someone doesn’t respond to one drug, there will be plenty of other choices, Dr. Aronne continued. People will be referred for surgery, but possibly only after they’ve not responded to medical treatment — or just the opposite. “In the United States, it’s much cheaper to have surgery, and I bet the insurance companies are going to make people have surgery before they can get the medicines,” he acknowledged.
A recent report from Morgan Stanley suggests that the global market for the newer weight-loss drugs could increase by 15-fold over the next 5 years as their benefits expand beyond weight loss and that as much as 9% of the US population will be taking the drugs by 2035, Dr. Aronne said, adding that he thinks 9% is an underestimate. By contrast, the number of patients treated by his team’s surgical program is down about 20%.
“I think it’s very clear that medical treatment is going to dominate,” he concluded. “But, it’s also possible that surgery could go up because so many people are going to be coming for medical therapy that we may wind up referring more for surgical therapy.”
‘Surgery Is Saving Lives’
Dr. Rubino is convinced that anti-obesity drugs will not make surgery obsolete, “but it will not be business as usual,” he told meeting attendees. “In fact, I think these drugs will expedite a process that is already ongoing — a transformation of bariatric into metabolic surgery.”
“Bariatric surgery will go down in history as one of the biggest missed opportunities that we, as medical professionals, have seen over the past many years,” he said. “It has been shown beyond any doubt to reduce all-cause mortality — in other words, it saves lives,” and it’s also cost effective and improves quality of life. Yet, fewer than 1% of people globally who meet the criteria actually get the surgery.
Many clinicians don’t inform patients about the treatment and don’t refer them for it, he said. “That would be equivalent to having surgery for CVD [cardiovascular disease], cancer, or other important diseases available but not being accessed as they should be.”
A big reason for the dearth of procedures is that people have unrealistic expectations about diet and exercise interventions for weight loss, he said. His team’s survey, presented at the 26th World Congress of the International Federation for the Surgery of Obesity and Metabolic Disorders, showed that 43% of respondents believed diet and exercise was the best treatment for severe obesity (BMI > 35). A more recent survey asked which among several choices was the most effective weight-loss intervention, and again a large proportion “believed wrongly that diet and exercise is most effective — more so than drugs or surgery — despite plenty of evidence that this is not the case.”
In this context, he said, “any surgery, no matter how safe or effective, would never be very popular.” If obesity is viewed as a modifiable risk factor, patients may say they’ll think about it for 6 months. In contrast, “nobody will tell you ‘I will think about it’ if you tell them they need gallbladder surgery to get rid of gallstone pain.”
Although drugs are available to treat obesity, none of them are curative, and if they’re stopped, the weight comes back, Dr. Rubino pointed out. “Efficacy of drugs is measured in weeks or months, whereas efficacy of surgery is measured in decades of durability — in the case of bariatric surgery, 10-20 years. That’s why bariatric surgery will remain an option,” he said. “It’s not just preventing disease, it’s resolving ongoing disease.”
Furthermore, bariatric surgery is showing value for people with established T2D, whereas in the past, it was mainly considered to be a weight-loss intervention for younger, healthier patients, he said. “In my practice, we’re operating more often in people with T2D, even those at higher risk for anesthesia and surgery — eg, patients with heart failure, chronic kidney disease, on dialysis — and we’re still able to maintain the same safety with minimally invasive laparoscopic surgery that we had with healthier patients.”
A vote held at the end of the session revealed that the audience was split about half and half in favor of drugs making bariatric surgery obsolete or not.
“I think we may have to duke it out now,” Dr. Aronne quipped.
Dr. Aronne disclosed being a consultant, speaker, and adviser for and receiving research support from Altimmune, Amgen, AstraZeneca, Eli Lilly, Intellihealth, Janssen, Novo Nordisk, Pfizer, Senda, UnitedHealth Group, Versanis, and others; he has ownership interests in ERX, Intellihealth, Jamieson, Kallyope, Skye Bioscience, Veru, and others; and he is on the board of directors of ERX, Jamieson Wellness, and Intellihealth/FlyteHealth. Dr. Rubino disclosed receiving research and educational grants from Novo Nordisk, Ethicon, and Medtronic; he is on the scientific advisory board/data safety advisory board for Keyron, Morphic Medical, and GT Metabolic Solutions; he receives speaking honoraria from Medtronic, Ethicon, Novo Nordisk, and Eli Lilly; and he is president of the nonprofit Metabolic Health Institute.

Dr. Aronne drew a parallel between treating obesity and the historic way of treating hypertension. Years ago, he said, “we waited too long to treat people. We waited until they had severe hypertension that in many cases was irreversible. What would you prefer to do now for obesity — have the patient lose weight with a medicine that is proven to reduce complications or wait until they develop diabetes, high blood pressure, heart disease and then have them undergo surgery to treat that?”
Looking ahead, “the trend could be to treat obesity before it gets out of hand,” he suggested. Treatment might start in people with a body mass index (BMI) of 27 kg/m2, who would be treated to a target BMI of 25. “That’s only a 10% or so change, but our goal would be to keep them in the normal range so they never go above that target. In fact, I think we’re going to be looking at people with severe obesity in a few years and saying, ‘I can’t believe someone didn’t treat that guy earlier.’ What’s going to happen to bariatric surgery if no one gets to a higher weight?”
The plethora of current weight-loss drugs and the large group on the horizon mean that if someone doesn’t respond to one drug, there will be plenty of other choices, Dr. Aronne continued. People will be referred for surgery, but possibly only after they’ve not responded to medical treatment — or just the opposite. “In the United States, it’s much cheaper to have surgery, and I bet the insurance companies are going to make people have surgery before they can get the medicines,” he acknowledged.
A recent report from Morgan Stanley suggests that the global market for the newer weight-loss drugs could increase by 15-fold over the next 5 years as their benefits expand beyond weight loss and that as much as 9% of the US population will be taking the drugs by 2035, Dr. Aronne said, adding that he thinks 9% is an underestimate. By contrast, the number of patients treated by his team’s surgical program is down about 20%.
“I think it’s very clear that medical treatment is going to dominate,” he concluded. “But, it’s also possible that surgery could go up because so many people are going to be coming for medical therapy that we may wind up referring more for surgical therapy.”
‘Surgery Is Saving Lives’
Dr. Rubino is convinced that anti-obesity drugs will not make surgery obsolete, “but it will not be business as usual,” he told meeting attendees. “In fact, I think these drugs will expedite a process that is already ongoing — a transformation of bariatric into metabolic surgery.”
“Bariatric surgery will go down in history as one of the biggest missed opportunities that we, as medical professionals, have seen over the past many years,” he said. “It has been shown beyond any doubt to reduce all-cause mortality — in other words, it saves lives,” and it’s also cost effective and improves quality of life. Yet, fewer than 1% of people globally who meet the criteria actually get the surgery.
Many clinicians don’t inform patients about the treatment and don’t refer them for it, he said. “That would be equivalent to having surgery for CVD [cardiovascular disease], cancer, or other important diseases available but not being accessed as they should be.”
A big reason for the dearth of procedures is that people have unrealistic expectations about diet and exercise interventions for weight loss, he said. His team’s survey, presented at the 26th World Congress of the International Federation for the Surgery of Obesity and Metabolic Disorders, showed that 43% of respondents believed diet and exercise was the best treatment for severe obesity (BMI > 35). A more recent survey asked which among several choices was the most effective weight-loss intervention, and again a large proportion “believed wrongly that diet and exercise is most effective — more so than drugs or surgery — despite plenty of evidence that this is not the case.”
In this context, he said, “any surgery, no matter how safe or effective, would never be very popular.” If obesity is viewed as a modifiable risk factor, patients may say they’ll think about it for 6 months. In contrast, “nobody will tell you ‘I will think about it’ if you tell them they need gallbladder surgery to get rid of gallstone pain.”
Although drugs are available to treat obesity, none of them are curative, and if they’re stopped, the weight comes back, Dr. Rubino pointed out. “Efficacy of drugs is measured in weeks or months, whereas efficacy of surgery is measured in decades of durability — in the case of bariatric surgery, 10-20 years. That’s why bariatric surgery will remain an option,” he said. “It’s not just preventing disease, it’s resolving ongoing disease.”
Furthermore, bariatric surgery is showing value for people with established T2D, whereas in the past, it was mainly considered to be a weight-loss intervention for younger, healthier patients, he said. “In my practice, we’re operating more often in people with T2D, even those at higher risk for anesthesia and surgery — eg, patients with heart failure, chronic kidney disease, on dialysis — and we’re still able to maintain the same safety with minimally invasive laparoscopic surgery that we had with healthier patients.”
A vote held at the end of the session revealed that the audience was split about half and half in favor of drugs making bariatric surgery obsolete or not.
“I think we may have to duke it out now,” Dr. Aronne quipped.
Dr. Aronne disclosed being a consultant, speaker, and adviser for and receiving research support from Altimmune, Amgen, AstraZeneca, Eli Lilly, Intellihealth, Janssen, Novo Nordisk, Pfizer, Senda, UnitedHealth Group, Versanis, and others; he has ownership interests in ERX, Intellihealth, Jamieson, Kallyope, Skye Bioscience, Veru, and others; and he is on the board of directors of ERX, Jamieson Wellness, and Intellihealth/FlyteHealth. Dr. Rubino disclosed receiving research and educational grants from Novo Nordisk, Ethicon, and Medtronic; he is on the scientific advisory board/data safety advisory board for Keyron, Morphic Medical, and GT Metabolic Solutions; he receives speaking honoraria from Medtronic, Ethicon, Novo Nordisk, and Eli Lilly; and he is president of the nonprofit Metabolic Health Institute.

Hot Flashes: Do They Predict CVD and Dementia?
This transcript has been edited for clarity.
I’d like to talk about a recent report in the journal Menopause linking menopausal symptoms to increased risk for cognitive impairment. I’d also like to discuss some of the recent studies that have addressed whether hot flashes are linked to increased risk for heart disease and other forms of cardiovascular disease (CVD).
Given that 75%-80% of perimenopausal and postmenopausal women have hot flashes and vasomotor symptoms, it’s undoubtedly a more complex relationship between hot flashes and these outcomes than a simple one-size-fits-all, yes-or-no question.
Increasing evidence shows that several additional factors are important, including the age at which the symptoms are occurring, the time since menopause, the severity of the symptoms, whether they co-occur with night sweats and sleep disruption, and the cardiovascular status of the woman.
Several studies suggest that women who have more severe hot flashes and vasomotor symptoms are more likely to have prevalent cardiovascular risk factors — hypertension, dyslipidemia, high body mass index, endothelial dysfunction — as measured by flow-mediated vasodilation and other measures.
It is quite plausible that hot flashes could be a marker for increased risk for cognitive impairment. But the question remains, are hot flashes associated with cognitive impairment independent of these other risk factors? It appears that the associations between hot flashes, vasomotor symptoms, and CVD, and other adverse outcomes, may be more likely when hot flashes persist after age 60 or are newly occurring in later menopause. In the Women’s Health Initiative observational study, the presence of hot flashes and vasomotor symptoms in early menopause was not linked to any increased risk for heart attack, stroke, total CVD, or all-cause mortality.
However, the onset of these symptoms, especially new onset of these symptoms after age 60 or in later menopause, was in fact linked to increased risk for CVD and all-cause mortality. With respect to cognitive impairment, if a woman is having hot flashes and night sweats with regular sleep disruption, performance on cognitive testing would not be as favorable as it would be in the absence of these symptoms.
This brings us to the new study in Menopause that included approximately 1300 Latino women in nine Latin American countries, with an average age of 55 years. Looking at the association between severe menopausal symptoms and cognitive impairment, researchers found that women with severe symptoms were more likely to have cognitive impairment.
Conversely, they found that the women who had a favorable CVD risk factor status (physically active, lower BMI, healthier) and were ever users of estrogen were less likely to have cognitive impairment.
Clearly, for estrogen therapy, we need randomized clinical trials of the presence or absence of vasomotor symptoms and cognitive and CVD outcomes. Such analyses are ongoing, and new randomized trials focused specifically on women in early menopause would be very beneficial.
At the present time, it’s important that we not alarm women about the associations seen in some of these studies because often they are not independent associations; they aren’t independent of other risk factors that are commonly linked to hot flashes and night sweats. There are many other complexities in the relationship between hot flashes and cognitive impairment.
We need to appreciate that women who have moderate to severe hot flashes (especially when associated with disrupted sleep) do have impaired quality of life. It’s important to treat these symptoms, especially in early menopause, and very effective hormonal and nonhormonal treatments are available.
For women with symptoms that persist into later menopause or who have new onset of symptoms in later menopause, it’s important to prioritize cardiovascular health. For example, be more vigilant about behavioral lifestyle counseling to lower risk, and be even more aggressive in treating dyslipidemia and diabetes.
JoAnn E. Manson, Professor of Medicine and the Michael and Lee Bell Professor of Women’s Health, Harvard Medical School; Chief, Division of Preventive Medicine, Brigham and Women’s Hospital, Boston, Massachusetts; and Past President, North American Menopause Society, 2011-2012, has disclosed the following relevant financial relationships: Received study pill donation and infrastructure support from Mars Symbioscience (for the COSMOS trial).

SGLT2 Inhibitor Reduces Risk for Neurodegenerative Diseases in T2D
MADRID — Patients with type 2 diabetes treated with sodium-glucose cotransporter 2 inhibitors (SGLT2is) show significant reductions in the risk of developing neurodegenerative disorders including Alzheimer’s disease, vascular dementia, and Parkinson’s disease, compared with those treated with other antidiabetic drugs, results from a large population-based cohort show.
“This was the largest nationwide population-based longitudinal cohort study to investigate the association between the use of SGLT2 inhibitors and the incidence of all-cause dementia and Parkinson’s disease,” said first author Hae Kyung Kim, MD, of the Department of Internal Medicine, Yonsei University College of Medicine, Seoul, South Korea, in presenting the findings at the annual meeting of the European Association for the Study of Diabetes.
Type 2 diabetes is known to increase the risk for neurodegenerative diseases such as dementia or Alzheimer’s disease, said Dr. Kim. Key factors attributed to the risk include shared pathophysiological mechanisms such as central nervous system insulin resistance and reduced cerebral glucose metabolism.
While research is lacking on the role of antidiabetic drugs in the treatment of neurodegenerative diseases, the researcher noted that “SGLT2 inhibitors, which have shown significant cardiorenal benefits and enhanced energy metabolism through ketogenesis, offer promise.”
To further investigate, Dr. Kim and her colleagues conducted the retrospective study, evaluating data on more than 1.3 million enrollees in Korea’s National Health Insurance Service Database who were aged 40 years or older, diagnosed with type 2 diabetes, and had initiated antidiabetic drugs between September 2014 and December 2019.
In the propensity score analysis, 358,862 patients were matched 1:1, in groups of 179,431 participants each, based on whether they were treated with SGLT2is or other oral antidiabetic drugs. Patients with a history of neurodegenerative disease, cancer, or use of glucagon-like peptide 1 receptor agonists were excluded.
The patients had a mean age of 57.8 years, 57.9% were men, and 6837 had incident dementia or Parkinson’s disease events reported.
With a mean follow-up of 2.88 years, after adjustment for key variables, those treated with SGLT2is had a 19% reduced risk of developing Alzheimer’s disease (adjusted hazard ratio [aHR], 0.81), a 31% reduced risk for vascular dementia (aHR, 0.69), and a 20% reduced risk for Parkinson’s disease (aHR, 0.80) compared with the non-SGLT2i group.
Furthermore, those receiving SGLT2i treatment had a 21% reduced risk for all-cause dementia (aHR, 0.79) and a 22% reduced risk for all-cause dementia and Parkinson’s disease compared with the oral antidiabetic drug group (aHR, 0.78) with a 6-month drug use lag period.
The association was observed regardless of SGLT2i exposure duration. Subgroup analyses indicated that the reductions in neurodegenerative disorders among those receiving SGLT2is were not associated with factors including age, sex, body mass index, blood pressure, glucose, lipid profiles, kidney function, health behaviors, comorbidities, diabetic complications, or other medication use.
Dr. Kim speculated that mechanisms underlying the reduced dementia risk could include SGLT2i effects of mitigating the common severe risk factors of type 2 diabetes and neurodegenerative diseases, including hypertension, heart failure, and chronic kidney disease, and improving hyperperfusion in the heart and cerebral vascular insufficiency.
Commenting on the study to this news organization, Erik H. Serné, MD, of the VU University Medical Centre, Amsterdam, the Netherlands, who comoderated the session, noted that “people with type 2 diabetes have a 50%-100% increased risk of developing dementia, particularly Alzheimer’s disease and vascular dementia.”
“The increasing prevalence of both conditions poses significant public health challenges, highlighting the need for effective prevention strategies and interventions.”
Currently, treatments for dementia are limited, with most primarily addressing symptoms and not the underlying cause of the neurodegenerative disease, he said.
He noted that, in addition to the effects mentioned by Dr. Kim, SGLT2is are also speculated to provide potential neuroprotective effects through improved glycemic control and insulin sensitivity, reduced inflammation and oxidative stress, enhanced mitochondrial function and energy metabolism, and reduced beta-amyloid and tau pathology.
“These mechanisms collectively may reduce the risk of cognitive decline, particularly in diabetic patients, and warrant further investigation in clinical trials to solidify the neuroprotective role of SGLT2 inhibitors,” said Dr. Serné.
In addition to their benefits in type 2 diabetes, SGLT2is “now offer hope in the prevention of dementia, a disease that has very limited therapeutic options thus far. The current data [presented by Dr. Kim] seem to corroborate this,” he added.
Dr. Kim and Dr. Serné had no disclosures to report.

‘Remarkable’ Weight Loss Seen With Safe, Tolerable Novel Oral Combination
MADRID — Amycretin, a dual-pathway, oral weight loss drug, led to up to 13% body weight loss in participants with overweight or obesity according to phase 1, first-in-human study data presented at the European Association for the Study of Diabetes (EASD) 2024 annual meeting.
Body weight loss was “remarkable for an orally delivered biologic,” said Agnes Gasiorek, PhD, senior clinical pharmacology specialist at Novo Nordisk, Måløv, Denmark, who presented the results. And “there was no plateauing of weight loss in the treatment period.”
With respect to the primary endpoint, stepwise dose escalation demonstrated that all tested dose levels up to and including 2 × 50 mg over a 12-week escalation period were safe and tolerable, Dr. Gasiorek reported.
The adverse events were in line with what was expected from targeting these receptors, and no new safety signals appeared during the study, she added.
Dual Pathways
Amycretin is a novel protein-based unimolecular amylin combined with a glucagon-like peptide 1 receptor agonist (GLP-1 RA) and is the first oral formulation of this combination under development.
The two components are both known to reduce appetite and energy intake and increase satiety, said Dr. Gasiorek, but amylin is considered to potentially increase leptin sensitivity and GLP-1 RAs are known to increase insulin secretion and biosynthesis. Together, the two components improve insulin sensitivity, decrease glucagon secretion, and lead to acute delay in gastric emptying.
The single-center, placebo-controlled, double-blind phase 1 study enrolled men and women aged 18-55 years (mean, 38-42 years across groups) with a body mass index of 25.0-39.9, without diabetes, and considered otherwise healthy.
Participants were randomly assigned to receive to receive oral amycretin (n = 95) or placebo (n = 29) once a day for up to 12 weeks. Study arms comprised single-ascending dosing (increasing from 1 mg/d to 25 mg), and multiple-ascending dosing. The latter consisted of multiple ascending doses (from 3 to 12 mg) over 10 days and multiple ascending doses (stepwise dose escalation, from 3 mg up to a final dose of 2 × 50 mg) over 12 weeks.
In her presentation at the EASD meeting, Dr. Gasiorek focused on results of the 12-week multiple ascending dose schedule with amycretin 50 mg (n = 16), amycretin 2 × 50 mg (n = 16), and placebo (n = 12).
The primary endpoint of the study was the number of treatment-emergent adverse events, while the area under the amycretin plasma concentration time curve and the maximum plasma concentration of amycretin were secondary endpoints.
The researchers also added percentage change in body weight after 12 weeks of treatment as an exploratory endpoint.
Safety Findings of Multiple Dosing
A total of 242 treatment-emergent adverse events were reported in the combined active and placebo groups and were of mild to moderate severity.
Treatment-emergent adverse events were found in 75% of the amycretin 50 mg group, 93.8% of the amycretin 2 × 50 mg group, and 33.3% of placebo recipients.
“Most adverse events reported were mild to moderate in severity and related to gastrointestinal discomfort (nausea and vomiting) and occurred in a dose-proportional manner,” reported Dr. Gasiorek.
Gastrointestinal events were experienced by 50%, 87.5%, and 16.7% of participants receiving amycretin 50 mg, amycretin 2 × 50 mg, and placebo, respectively (112 in total).
Decreased appetite was also found in 56.3%, 81.3%, and 16.7% of the amycretin 50 mg, amycretin 2 × 50 mg, and placebo groups, respectively.
Two serious adverse events occurred, one of which was acute cholecystitis and the other diabetic ketoacidosis; “however, the [latter] participant was found to have autoantibodies for beta cells before treatment and was later diagnosed with type 1 diabetes,” Dr. Gasiorek said.
Body Weight Reduction
Participants on 50 mg amycretin lost an average of 10.4% of their body weight (estimated treatment difference vs placebo, –9.2; 95% CI, –12.0 to –6.5), whereas those on 2 × 50 mg amycretin lost 13.1% of their body weight (estimated treatment difference vs placebo, –11.8; 95% CI, –14.6 to –9.0). Placebo group participants lost 1.2% of their body weight over the 12 weeks.
Although no plateauing of weight loss was seen, said Dr. Gasiorek, it is important to consider the relatively short treatment duration and the limited time on the final dose, which could potentially introduce bias.
To date, weight loss medications based on GLP-1 RA technology are injectables. A combination of the injectable amylin analogue cagrilintide and the GLP-1 RA semaglutide is also being explored as a subcutaneous treatment solution.
In a comment, Martin Holst Lange, MD, PhD, executive vice president of development at Novo Nordisk, said that “amycretin is the first treatment to harness the two distinct biological pathways stimulated by amylin and GLP-1 in a single molecule.”
The safety and tolerability profiles and the magnitude of weight loss support further development of amycretin in patients with overweight or obesity, said Dr. Lange, who noted that the company was awaiting data from the ongoing phase 1 trial with subcutaneous amycretin, expected in 2025.
Having heard the presentation, co-moderator Timo Müller, PhD, professor at Ludwig Maximilian University of Munich, Germany, gave a considered response. “The drug was relatively well tolerated, with the typical GLP-1–induced GI [gastrointestinal] adverse effects being the most frequently reported.”
But he pointed out that questions remain. “We still need to know whether, at the given dose, the drug outperforms best-in-class drugs like semaglutide or tirzepatide at the highest approved doses. Furthermore, it warrants clarification if and to what extent the activation of the amylin receptor contributes to the shown effect and if and to what extent the glycemic benefits result from activation of the glucagon receptor (amylin improved glycemia by decreasing the secretion of glucagon). In any way, the current data remain friendly and support phase 2 development.”
Oral Meds Could Bring Down Cost
Commenting on the data, Nerys Astbury, PhD, associate professor of diet and obesity at Nuffield Department of Primary Health Care Sciences, University of Oxford, England, said, “It is important to note that whilst the participants in this trial did lose weight over the 12-week study — and this was statistically more weight than in the placebo group — this study was not designed or powered to detect differences in body weight over longer periods of time.”
If the results are confirmed in future studies, amycretin might widen the treatment options and introduce competition, probably bringing down the costs in the longer-term, said Dr. Astbury, who welcomes the prospect.
“It is possible that some people might find the oral medications more acceptable than the injectable GLP-1 agonists currently available,” she said. And the current options are expensive, “which raises challenges to a taxpayer-funded health system like the NHS [National Health Service].”
“Furthermore, if the growing number of oral obesity medications prove safe, tolerable, and effective ... they are likely to significantly reduce the risks of developing many complications of obesity.”
Naveed Sattar, MD, professor of cardiometabolic medicine and honorary consultant, University of Glasgow, Scotland, agreed. “The more medicines coming forward to treat obesity, the better,” he said. In particular, oral medications would be more easily available, and cheaper, “for the many millions around the world struggling with obesity and its complications.”
Dr. Gasiorek declares she is an employee of and a shareholder in Novo Nordisk. Dr. Astbury declares no financial disclosures. Dr. Sattar declares having consulted for several companies that make diabetes medicines but also contributed to several lifestyle trials. For Novo Nordisk, he has consulted for the company on advisory boards, but not on any of their weight loss drug trial committees, and he is on the steering committee for the ZEUS trial, which is not a weight loss trial product but an anti-inflammatory. He does not have any shares for any product in health etc. He declares consulting fees and/or speaker honoraria from Abbott Laboratories, Afimmune, Amgen, AstraZeneca, Boehringer Ingelheim, Eli Lilly, Hanmi Pharmaceuticals, Janssen, Merck Sharp & Dohme, Novartis, Novo Nordisk, Pfizer, and Sanofi, and grant support paid to his university from AstraZeneca, Boehringer Ingelheim, Novartis, and Roche Diagnostics.

MADRID — Amycretin, a dual-pathway, oral weight loss drug, led to up to 13% body weight loss in participants with overweight or obesity according to phase 1, first-in-human study data presented at the European Association for the Study of Diabetes (EASD) 2024 annual meeting.
Body weight loss was “remarkable for an orally delivered biologic,” said Agnes Gasiorek, PhD, senior clinical pharmacology specialist at Novo Nordisk, Måløv, Denmark, who presented the results. And “there was no plateauing of weight loss in the treatment period.”
With respect to the primary endpoint, stepwise dose escalation demonstrated that all tested dose levels up to and including 2 × 50 mg over a 12-week escalation period were safe and tolerable, Dr. Gasiorek reported.
The adverse events were in line with what was expected from targeting these receptors, and no new safety signals appeared during the study, she added.
Dual Pathways
Amycretin is a novel protein-based unimolecular amylin combined with a glucagon-like peptide 1 receptor agonist (GLP-1 RA) and is the first oral formulation of this combination under development.
The two components are both known to reduce appetite and energy intake and increase satiety, said Dr. Gasiorek, but amylin is considered to potentially increase leptin sensitivity and GLP-1 RAs are known to increase insulin secretion and biosynthesis. Together, the two components improve insulin sensitivity, decrease glucagon secretion, and lead to acute delay in gastric emptying.
The single-center, placebo-controlled, double-blind phase 1 study enrolled men and women aged 18-55 years (mean, 38-42 years across groups) with a body mass index of 25.0-39.9, without diabetes, and considered otherwise healthy.

FROM EASD 2024
Genitourinary Symptoms in Men: Canaries in the Coal Mine for Underlying Chronic Disease
At age 57, a senior scientific researcher in Santa Barbara, California, complained of chronic erectile dysfunction (ED) in what had been a sexually active marriage. “I just couldn’t get an erection, let alone sustain one. Apart from that, I maybe felt a bit tired but generally okay,” he said. Though seemingly well otherwise, 18 months later he was dead of a hereditary right-sided colon cancer.
While not all cases of ED are associated with a dire outcome, the genitourinary signals of ED and lower urinary tract symptoms (LUTS), especially nocturia, serve as sentinel indicators of the presence of, or risk factors for, serious chronic conditions. These commonly include cardiovascular disease (CVD), diabetes, and metabolic syndrome and are associated with obesity, depression, and obstructive sleep apnea.
Sometimes these serious conditions may stay under the radar until men seek help for ED or LUTS.
“We know that among men who had a heart attack, 50% had some degree of ED within 3 years of their cardiac event,” Sam Tafari, MBBS, of the Endocrine and Metabolic Unit at Royal Adelaide Hospital in Adelaide, South Australia, said in an interview.
That’s the bad news. The good news is that these two problems may specifically incentivize men to seek timely care for serious conditions they might otherwise not get, according to Dr. Tafari. And primary care doctors are ideally positioned to get men early multifaceted care. He recently coauthored a call to action on this issue in a review appearing in the Journal of Men’s Health.
In Dr. Tafari’s experience, most patients seeking urological care are unaware of the multiple conditions linked to ED and LUTS. “Many consider these to be due to issues like low testosterone, which actually make up a very small proportion of cases of ED,” he said. Aging, obesity, inactivity, smoking, alcohol abuse, and prescription and street drugs can also contribute to the development of ED.
In most affected men, ED is of vascular etiology, with endothelial dysfunction of the inner lining of blood vessels and smooth muscle the common denominator.
This dysfunction causes inadequate blood supply to both the coronary and the penile arteries, so ED and CVD are considered different manifestations of the same systemic disorder. Because the tumescence-controlling cavernosal vessels of the penis are considerably smaller, the same level of arteriopathy causes a more severe reduction in blood in the erectile tissue. As a result, ED often precedes CVD and presents an early opportunity to screen men for CVD.
As to the mechanisms behind LUTS, Peter N. Tsambarlis, MD, a urologist at Northwestern Medicine in Chicago, subscribes to the inflammation theory. “Suboptimal health issues such as high [blood] pressure, blood lipids, and blood glucose lead to chronic widespread inflammation, which makes the bladder less flexible as a storage vessel,” he explained. “It’s not able to stretch adequately overnight to hold the urine until morning.”
Ask Early, Ask Often
Jeffrey P. Weiss, MD, PhD, chair of the Department of Urology at SUNY Downstate Health Sciences University in Brooklyn, New York, has done research that uncovered a relationship between structural cardiac disease and nocturia. “So if you had to ask a patient a single question that would point to a global health issue, it would be ‘Do you have frequent nighttime urination,’ ” he said.
It’s never too soon to ask men about these symptoms, said Dr. Tsambarlis. The best time to raise issues of ED and LUTS is when a man enters primary care — regardless of age or absence of symptoms. “That way you have a baseline and can watch for changes and do early intervention as needed. Men don’t usually want to bring up sexual dysfunction or urinary health, but asking doesn’t need to dominate the visit,” he said.
Dr. Tafari recommends that primary care physicians adopt a targeted approach using ED and nocturia as entry points for engaging men in their healthcare. While acknowledging that primary care physicians have an ever-growing checklist of questions to ask patients and hardly need one more thing to screen for, he suggests asking two quick, and easy “before you go” genitourinary queries:
- Are you having trouble with erections or having sex?
- Are you getting up at night to pass urine more than once?
“The men really appreciate being asked,” he said. “But what worries me is all the men we don’t see who have these symptoms but don’t know they’re important, and no one is asking about them.”
Gideon Richards, MD, a urologist at the Northwell Health Physician Partners Smith Institute for Urology at Garden City, and director of Men’s Health, Central Region, for Northwell Health in New Hyde Park, both in New York, said erectile problems should not wait for specialty care. By the time men with ED are referred to urology, they may already have failed treatment with first-line phosphodiesterase 5 inhibitor therapy, he said. “A significant proportion will have arteriogenic erectile dysfunction, a measurable decrease in the amount of blood flow into the erectile bodies.”
Addressing the Issue
Addressing genitourinary-signaled issues has the double benefit of easing ED and LUTS and improving men’s health and longevity and may help narrow the worldwide gender gap in life expectancy. As a recent global analysis found, there’s a 5-year longevity disparity favoring women over men. Biology aside, men do not access healthcare as often as women, who consult their general practitioners regularly throughout their lifespan for multiple reasons, including reproductive care, and more screening programs are aimed at women.
Added Dr. Tsambarlis, “Men should know that losing weight and switching to a healthy lifestyle can improve sexual function about half as much as phosphodiesterase 5 inhibitors such as sildenafil [Viagra] or tadalafil [Cialis].”
“Many, however, would prefer just to take drugs rather than change their lifestyle and lose weight. There are certainly effective options available, but these are not uniformly effective,” said Dr. Weiss.
Dr. Tafari’s group is designing a short, simple, culturally acceptable screening tool for use in primary care practice and will monitor its impact on physician prescribing habits and overall men’s health outcomes.
Dr. Tafari received funding from the Hospital Research Foundation and Freemasons Centre for Male Health and Wellbeing in Adelaide, South Australia. Dr. Tafari, Dr. Tsambarlis, Dr. Weiss, and Dr. Richards had no relevant conflicts of interest to declare.

It’s never too soon to ask men about these symptoms, said Dr. Tsambarlis. The best time to raise issues of ED and LUTS is when a man enters primary care — regardless of age or absence of symptoms. “That way you have a baseline and can watch for changes and do early intervention as needed. Men don’t usually want to bring up sexual dysfunction or urinary health, but asking doesn’t need to dominate the visit,” he said.
Dr. Tafari recommends that primary care physicians adopt a targeted approach using ED and nocturia as entry points for engaging men in their healthcare. While acknowledging that primary care physicians have an ever-growing checklist of questions to ask patients and hardly need one more thing to screen for, he suggests asking two quick, and easy “before you go” genitourinary queries:
- Are you having trouble with erections or having sex?
- Are you getting up at night to pass urine more than once?
“The men really appreciate being asked,” he said. “But what worries me is all the men we don’t see who have these symptoms but don’t know they’re important, and no one is asking about them.”
Gideon Richards, MD, a urologist at the Northwell Health Physician Partners Smith Institute for Urology at Garden City, and director of Men’s Health, Central Region, for Northwell Health in New Hyde Park, both in New York, said erectile problems should not wait for specialty care. By the time men with ED are referred to urology, they may already have failed treatment with first-line phosphodiesterase 5 inhibitor therapy, he said. “A significant proportion will have arteriogenic erectile dysfunction, a measurable decrease in the amount of blood flow into the erectile bodies.”
Addressing the Issue
Addressing genitourinary-signaled issues has the double benefit of easing ED and LUTS and improving men’s health and longevity and may help narrow the worldwide gender gap in life expectancy. As a recent global analysis found, there’s a 5-year longevity disparity favoring women over men. Biology aside, men do not access healthcare as often as women, who consult their general practitioners regularly throughout their lifespan for multiple reasons, including reproductive care, and more screening programs are aimed at women.
Added Dr. Tsambarlis, “Men should know that losing weight and switching to a healthy lifestyle can improve sexual function about half as much as phosphodiesterase 5 inhibitors such as sildenafil [Viagra] or tadalafil [Cialis].”
“Many, however, would prefer just to take drugs rather than change their lifestyle and lose weight. There are certainly effective options available, but these are not uniformly effective,” said Dr. Weiss.
Dr. Tafari’s group is designing a short, simple, culturally acceptable screening tool for use in primary care practice and will monitor its impact on physician prescribing habits and overall men’s health outcomes.

At age 57, a senior scientific researcher in Santa Barbara, California, complained of chronic erectile dysfunction (ED) in what had been a sexually active marriage. “I just couldn’t get an erection, let alone sustain one. Apart from that, I maybe felt a bit tired but generally okay,” he said. Though seemingly well otherwise, 18 months later he was dead of a hereditary right-sided colon cancer.
While not all cases of ED are associated with a dire outcome, the genitourinary signals of ED and lower urinary tract symptoms (LUTS), especially nocturia, serve as sentinel indicators of the presence of, or risk factors for, serious chronic conditions. These commonly include cardiovascular disease (CVD), diabetes, and metabolic syndrome and are associated with obesity, depression, and obstructive sleep apnea.
Sometimes these serious conditions may stay under the radar until men seek help for ED or LUTS.
“We know that among men who had a heart attack, 50% had some degree of ED within 3 years of their cardiac event,” Sam Tafari, MBBS, of the Endocrine and Metabolic Unit at Royal Adelaide Hospital in Adelaide, South Australia, said in an interview.
That’s the bad news. The good news is that these two problems may specifically incentivize men to seek timely care for serious conditions they might otherwise not get, according to Dr. Tafari. And primary care doctors are ideally positioned to get men early multifaceted care. He recently coauthored a call to action on this issue in a review appearing in the Journal of Men’s Health.
In Dr. Tafari’s experience, most patients seeking urological care are unaware of the multiple conditions linked to ED and LUTS. “Many consider these to be due to issues like low testosterone, which actually make up a very small proportion of cases of ED,” he said. Aging, obesity, inactivity, smoking, alcohol abuse, and prescription and street drugs can also contribute to the development of ED.
In most affected men, ED is of vascular etiology, with endothelial dysfunction of the inner lining of blood vessels and smooth muscle the common denominator.
This dysfunction causes inadequate blood supply to both the coronary and the penile arteries, so ED and CVD are considered different manifestations of the same systemic disorder. Because the tumescence-controlling cavernosal vessels of the penis are considerably smaller, the same level of arteriopathy causes a more severe reduction in blood in the erectile tissue. As a result, ED often precedes CVD and presents an early opportunity to screen men for CVD.
As to the mechanisms behind LUTS, Peter N. Tsambarlis, MD, a urologist at Northwestern Medicine in Chicago, subscribes to the inflammation theory. “Suboptimal health issues such as high [blood] pressure, blood lipids, and blood glucose lead to chronic widespread inflammation, which makes the bladder less flexible as a storage vessel,” he explained. “It’s not able to stretch adequately overnight to hold the urine until morning.”
Ask Early, Ask Often

Early vs Late Fast Window: Is One More Effective?
MADRID — A daily 8-hour eating window controls blood glucose whether followed early or late in the day by people at risk for type 2 diabetes, showed a time-restricted eating (TRE) study presented at the European Association for the Study of Diabetes (EASD) 2024 Annual Meeting.
The study, examining shifting the time of day for the 8-hour eating window along with a tightly controlled diet, found that 8 hours of TRE — whether early or late in the day — led to a significant improvement in the time spent within a normal daily blood glucose range and in glycemic variability.
“We didn’t show a benefit in terms of early versus late TRE, but we did show a benefit of time-restricted eating within a window of 8 h/d,” said study lead Kelly Bowden Davies, MSc, PhD, from Manchester Metropolitan University, Manchester, England, when presenting the work. “It doesn’t matter when you restrict eating, but if you restrict it to 8 hours then, according to our study, it benefits glycemic control in people at risk of type 2 diabetes.”
The researcher added that the effect was seen after only 3 days, and “demonstrates its therapeutic role in adults at risk of type 2 diabetes, which warrants investigation in the longer term.”
The current study examined the effect of shifting the time of day for the TRE window from early (8 AM-4 PM) to late (12 PM-8 PM) in people at risk of developing type 2 diabetes due to a lifestyle characterized as sedentary and poor diet.
Previous studies indicate that TRE, which limits when, but not what, individuals eat, can improve insulin sensitivity and A1c in people at risk for type 2 diabetes.
But Dr. Bowden Davies pointed out that the effect of TRE on glycemic variability remained unclear. While prior work had attributed the positive effects of TRE to reduced energy intake, this study provided a diet where energy consumption matched energy expenditure — taking into account sex, age, weight, height, and activity level, termed a “eucaloric” diet.
“Some research groups recognize that if we manipulate the time at which we eat, then we can better align with circadian metabolic rhythms to improve whole body insulin sensitivity and glycemic variability,” explained Dr. Bowden Davies. “It may be that eating in the morning may be better aligned [with circadian rhythms] and cause greater improvement in glucose control.”
Three-Day TRE Plan Led to Blood Glucose Control
In a cross-over study design, all 15 participants were randomized to follow the early and late TRE regimens with a 7-day washout period in the middle. Participants had a mean body mass index (BMI) of 27.7 kg/m2, had a mean waist circumference of 73 cm, were sedentary, and followed a poor diet.
“Participants were normoglycemic so had good glucose control, but due to having overweight and obesity, they are considered as having risk factors for the development of type 2 diabetes,” noted Dr. Bowden Davies.
Before the TRE period, participants provided researchers with a dietary record. If they started on the early TRE, they crossed over to the late TRE after the washout period, and vice versa, she explained.
Continuous glucose monitoring (FreeStyle Libre 2, Abbott Laboratories) was carried out across the study to assess the daily time spent in euglycemia (3.9-7.8 mmol/L) and provide markers of glycemic variability, including mean absolute glucose, coefficient of variation, and mean amplitude of glucose excursions. Blood draws both pre- and post-TRE period provided biochemical measurements, and anthropometric readings were also taken.
There were nine female participants, with a mean age of 52 years, a BMI of 28 kg/m2, and an A1c level of 37.9 mmol/mol (5.6%). They tended to snack across an eating period of 14 h/d or more (habitual eating). They were assigned to two different investigational eating patterns for 3-day durations: Early or late, and these findings were compared with those from participants who continued their habitual eating.
Participants were provided with a eucaloric, standardized diet [50% carbohydrates, 30% fat, and 20% protein] to be eaten during the TRE period, whereas they ate as usual (ie, as and what they wanted) when not on the TRE regimen.
No changes were seen in the biochemistry markers assessed. “Given they only followed the TRE for 3 days, this is unsurprising,” remarked Dr. Bowden Davies. “We did see weight loss after only 3 days of TRE of around 1.1 kg across the two interventions,” she reported.
Referring to the early vs late TRE regimen, she added that “we didn’t see a benefit [no significant differences in glycemic control] of early compared with late TRE, but we did see a benefit of restricting the eating window to 8 h/d, so both conditions [early and late TRE regimens] had a benefit on glucose control.”
Variables of blood glucose control were also reduced while on the TRE regimen compared with habitual eating (more than 14 h/d), with significantly increased time spent within the normal blood glucose range on average by 3.3%, and also reduced mean absolute glucose by 0.6 mmol/L, coefficient of variation by 2.6%, and mean amplitude of glucose excursions by 0.4 mmol/L.
“Within 3 days, this is quite striking,” Dr. Bowden Davies pointed out.
She added that these data were interim analyses, but “these are positive in terms of participants seeing a benefit in glucose control and glycemic variability, which is a risk factor for developing type 2 diabetes but also for microvascular complications. We also saw improved time in range in terms of tight glucose control.
“Even in 3 days, there were small, subtle differences which are subclinical — but this is not a clinical cohort. The results are statistically significant and a promising piece of data to suggest a feasible intervention that could be translated across different populations,” she said, adding that over a longer time period, changes between TRE timing might show changes in people at risk for type 2 diabetes who don’t have compromised circadian rhythms.
Moderating the session was Lutgarda Bozzetto, MD, from the University of Naples Federico II, Naples, Italy. She told this news organization, “It’s a hot topic right now, and the finding that there’s no difference in the time of day when the restricted eating is done suggests that in people at risk of diabetes, the hormonal flux and cycle involved in blood glucose control is not so strong or sensitive.”
Using a continuous glucose monitor, they can look at their blood glucose levels after eating, and this might “be powerful in guiding behavioral change,” said Dr. Bozzetto.
Abbott Laboratories funded the continuous glucose monitoring. Neither Dr. Bowden Davies nor Dr. Bozzetto had any other relevant financial disclosures.

Beyond Weight Loss, Limited Bariatric Surgery Benefits in Older Adults
TOPLINE:
For older adults with obesity, bariatric surgery does not appear to significantly reduce the risk for obesity-related cancer and cardiovascular disease (CVD), as it does in younger adults.
METHODOLOGY:
- Bariatric surgery has been shown to decrease the risk for obesity-related cancer and CVD but is typically reserved for patients aged < 60 years. Whether the same holds for patients who undergo surgery at older ages is unclear.
- Researchers analyzed nationwide data from three countries (Denmark, Finland, and Sweden) to compare patients with no history of cancer or CVD and age ≥ 60 years who underwent bariatric surgery against matched controls who received nonoperative treatment for obesity.
- The main outcome was obesity-related cancer, defined as a composite outcome of breast, endometrial, esophageal, colorectal, and kidney cancer. The secondary outcome was CVD, defined as a composite of myocardial infarction, ischemic stroke, and cerebral hemorrhage.
- Analyses were adjusted for diabetes, hypertension, peripheral vascular disease, chronic obstructive pulmonary disease, kidney disease, and frailty.
TAKEAWAY:
- Of the 15,300 patients (66.4% women) included, 2550 underwent bariatric surgery (including gastric bypass in 1930) and 12,750 matched controls received nonoperative treatment for obesity.
- During a median 5.8 years of follow-up, 658 (4.3%) people developed obesity-related cancer and 1436 (9.4%) developed CVD.
- Bariatric surgery in adults aged ≥ 60 years was not associated with a reduced risk for obesity-related cancer (hazard ratio [HR], 0.81) or CVD (HR, 0.86) compared with matched nonoperative controls.
- Bariatric surgery appeared to be associated with a decreased risk for obesity-related cancer in women (HR, 0.76).
- There was a decreased risk for both obesity-related cancer (HR, 0.74) and CVD (HR, 0.82) in patients who underwent gastric bypass.
IN PRACTICE:
“The findings from this study suggest a limited role of bariatric surgery in older patients for the prevention of obesity-related cancer or cardiovascular disease,” the authors wrote, noting that this “may be explained by the poorer weight loss and resolution of comorbidities observed in patients who underwent surgery at an older age.”
SOURCE:
The study, with first author Peter Gerber, MD, PhD, Department of Surgery, Capio St Göran’s Hospital, Stockholm, Sweden, was published online in JAMA Network Open.
LIMITATIONS:
Data on smoking status and body mass index were not available. The observational design limited the ability to draw causal inferences. The null association between bariatric surgery and outcomes may be due to limited power.
DISCLOSURES:
The study was funded by the Swedish Society of Medicine. The authors reported no conflicts of interest.

METHODOLOGY:
- Bariatric surgery has been shown to decrease the risk for obesity-related cancer and CVD but is typically reserved for patients aged < 60 years. Whether the same holds for patients who undergo surgery at older ages is unclear.
- Researchers analyzed nationwide data from three countries (Denmark, Finland, and Sweden) to compare patients with no history of cancer or CVD and age ≥ 60 years who underwent bariatric surgery against matched controls who received nonoperative treatment for obesity.
- The main outcome was obesity-related cancer, defined as a composite outcome of breast, endometrial, esophageal, colorectal, and kidney cancer. The secondary outcome was CVD, defined as a composite of myocardial infarction, ischemic stroke, and cerebral hemorrhage.
- Analyses were adjusted for diabetes, hypertension, peripheral vascular disease, chronic obstructive pulmonary disease, kidney disease, and frailty.
TAKEAWAY:
- Of the 15,300 patients (66.4% women) included, 2550 underwent bariatric surgery (including gastric bypass in 1930) and 12,750 matched controls received nonoperative treatment for obesity.
- During a median 5.8 years of follow-up, 658 (4.3%) people developed obesity-related cancer and 1436 (9.4%) developed CVD.
- Bariatric surgery in adults aged ≥ 60 years was not associated with a reduced risk for obesity-related cancer (hazard ratio [HR], 0.81) or CVD (HR, 0.86) compared with matched nonoperative controls.
- Bariatric surgery appeared to be associated with a decreased risk for obesity-related cancer in women (HR, 0.76).
- There was a decreased risk for both obesity-related cancer (HR, 0.74) and CVD (HR, 0.82) in patients who underwent gastric bypass.
IN PRACTICE:
“The findings from this study suggest a limited role of bariatric surgery in older patients for the prevention of obesity-related cancer or cardiovascular disease,” the authors wrote, noting that this “may be explained by the poorer weight loss and resolution of comorbidities observed in patients who underwent surgery at an older age.”
SOURCE:
The study, with first author Peter Gerber, MD, PhD, Department of Surgery, Capio St Göran’s Hospital, Stockholm, Sweden, was published online in JAMA Network Open.
LIMITATIONS:
Data on smoking status and body mass index were not available. The observational design limited the ability to draw causal inferences. The null association between bariatric surgery and outcomes may be due to limited power.
DISCLOSURES:
The study was funded by the Swedish Society of Medicine. The authors reported no conflicts of interest.

Diabetes Increases Injury Risk: A Troubling Trend
In 2024, a record number of people are celebrating their 65th birthdays. Increasing age is associated with a higher risk for falls, fractures, and other injuries that may require hospitalization.
In older adults with type 1 and type 2 diabetes, the risk for falls is double that seen in older people without these conditions. Increased clinician awareness of the many factors that result in this higher risk in people with diabetes, and timely implementation of strategies to prevent falls, are essential.
The annual incidence of falls in people with diabetes older than 65 years is about 39%, compared with 19% among those without diabetes. People with diabetes on insulin face an even greater increased risk for falls compared with those who are not using insulin (94% vs 27% increased risk).
Many well-known aspects of diabetes contribute to this greater risk. These include decreased sensorimotor function, musculoskeletal and neuromuscular deficits, foot and body pain, poor vision, hypoglycemic episodes, pharmacologic complications, and problems with hearing and balance.
Optimal management of diabetes and its complications is essential, and the American Diabetes Association has developed clear guidelines for clinicians to follow to reduce the risk for diabetes related complications and manage these conditions.
The prevalence of diabetic peripheral neuropathy increases with age and duration of diabetes. People with diabetic peripheral neuropathy and diminished sensation on their feet are at increased risk for loss of postural control. Loss of proprioceptive feedback (the ability to sense movement, action and location) during standing and walking leads increases the risk for falls.
In addition, less physical activity, impaired muscle strength, and suboptimal postural control all influence gait patterns and increase the risk for falling. Adults with diabetes have a two to three times higher risk for sarcopenia (decreased muscle strength and muscle mass). They also have low plantar flexion strength, causing increased displacement of their center of gravity, which in turn reduces their maximum forward stride and may result in falls and injury.
Many people with diabetes experience neuropathic foot and body pain, requiring psychotropic and other medications that may exacerbate the risk, such as amitriptyline and duloxetine. Furthermore, older adults with diabetes are more likely to take more prescription medications and may be more sensitive to effects of multiple medications than are individuals without diabetes.
A hazard of managing diabetes, particularly with insulin, is the increased risk for unexpected low blood glucose levels. These episodes can also occur in patients taking certain kinds of oral diabetes medications, but they are more common in those on insulin. Low blood glucose can cause dizziness, confusion, and postural instability, increasing the risk for falling.
Diabetic eye complications include retinopathy, macular edema, cataracts, and glaucoma. In a study of close to 10,000 middle-aged and older adults with diabetes, those with moderate eye complications had almost double the risk of falls as those without eye complications.
Another concern with diabetes is its effect on nerves and blood vessels in the inner ear, leading to a negative effect on balance and hearing loss, both of which are also associated with a higher risk for falling and injury.
Clinicians can reduce the risk for falls in patients by taking measures to improve diabetes control and reduce the risk for microvascular disease affecting the nerves, eyes, and ears.
In addition, exercises that optimize muscle mass, bone strength, gait, and balance, and use of specialized footwear in people with neuropathy, may reduce fall risk. Chair yoga and tai chi have also been shown to be helpful. Clinicians can also advise patients on commonsense strategies to implement in their homes, such as ensuring proper lighting, reducing, clutter and minimizing the use of floor rugs.
The risk for falls and the associated risk for fracture and possible hospitalization are of significant concern in older adults — particularly those with diabetes, and even more so in those with diabetes who are on insulin. It is our responsibility as clinicians to implement strategies to optimize diabetes control in our patients and monitor them for microvascular and other complications that may increase this risk, and manage them appropriately if and when these complications occur.
