Interventions during holidays and school vacations can help prevent children and adults gaining weight, according to a recent systematic review and meta-analysis published in Obesity Reviews.

Evidence suggests that certain times of the year, such as the Christmas holidays and summer vacations, are associated with weight gain. In adults, up to 50% of the total annual weight gain occurs during December.

In 2023, the United Nations Children’s Fund reported that more than four million children younger than 5 years and nearly 50 million children and adolescents aged 5-19 years in Latin America and the Caribbean were affected by overweight. Among adults, more than 50% of individuals in every country in the region live with obesity.

These alarming figures call for urgent action from governments, healthcare professionals, and multidisciplinary teams to implement prevention strategies and promote further research.

 

Study Significance

Michelle Maree Haby de Sosa, PhD, an epidemiologist and researcher at the Department of Chemical-Biological and Nutritional Sciences at the University of Sonora, Hermosillo, Mexico, led the study. She explained that the research team first conducted a narrative review on weight gain during the festive season. “We found that the 6 weeks between December and mid-January represent a critical period when people gain half the weight they put on all year. This highlights the importance of addressing obesity and overweight by promoting lifestyle changes and prevention strategies to tackle this public health issue.”

The researchers then conducted a systematic review of global interventions not only to publish findings but also to educate healthcare professionals and stakeholders. They searched databases such as Medline, EMBASE, PsycINFO, SciELO, LILACS, and Cochrane, focusing on randomized controlled trials. These were supplemented with gray literature and references from relevant articles, as well as additional data requested from study authors.

 

Key Findings

The review included studies from the United States (10), the United Kingdom (one), and Chile (one). Of these, two had a low risk for bias, two moderate, seven high, and one critical.

Most interventions targeted school-aged children or adults. According to Haby de Sosa, achieving consistent results in adolescents was challenging due to the difficulty of changing behaviors in this age group. In contrast, interventions for school-aged children were implemented primarily during day camp visits, where participants were divided into control and intervention groups.

The interventions included nutrition classes, physical activity, and the provision of healthy meals, which resulted in less weight gain compared with control groups.

In children, the meta-analysis of four of seven studies conducted during summer vacations (six interventions) found a small but significant reduction in body mass index z-scores in the intervention group (−0.06; 95% CI, −0.10 to −0.01; P = .01; I² = 0%; very low-certainty evidence).

Among adults, interventions also generally proved effective, despite variations in implementation. A meta-analysis of five studies involving 462 participants (234 intervention, 228 control) showed a slight reduction in body weight (−0.99 kg; 95% CI, −2.15 to 0.18; P = 0.10; I² = 89%).

Three key intervention areas were identified: Nutrition, physical activity, and psychological support including behavioral and cognitive elements. Strict diets were generally not a priority; instead, participants were advised to reduce consumption of high-calorie food and sugary beverages while increasing their intake of vegetables.

 

Promising Interventions

The study highlighted specific interventions for children and adults:

  • Children: 6- to 8-week summer camps with daily physical activities such as sports and crafts, complemented by free, nutritious meals.
  • Adults: Daily weight monitoring paired with nutrition counseling based on social cognitive theory. Interventions lasted 4 to 8 weeks, spanning mid-November to early January.

Expert Recommendations

Carlos Cristi-Montero, PhD, a researcher at Pontificia Universidad Católica de Valparaíso, Chile, and an author of a Chilean intervention study, shared insights with this news organization.

He emphasized the importance of portion control for children. “During the holidays, families prepare calorie-rich dishes but often fail to consider portion sizes,” he noted. “Children are treated like adults, which contributes to excessive caloric intake. Our interventions focused on teaching people about portion control, the caloric content of their meals, and the risks of overweight and obesity, as well as the benefits of healthy eating.”

He also stressed the importance of evaluating not just weight but body composition, using tools like dual-energy x-ray absorptiometry to measure fat and muscle mass.

Cristi-Montero also highlighted the importance of physical activity: “We emphasize the value of exercise and staying active as key strategies to prevent weight gain.”

 

Steps for Successful Interventions

Educating teachers and parents to reinforce healthy behaviors is also vital, according to Cristi-Montero, as obesity impacts not only metabolic health but also academic performance and mental health.

Both Haby de Sosa and Cristi-Montero agreed that primary care professionals have an important role in driving effective interventions, alongside participation in research to refine prevention strategies. Multidisciplinary teams — including nutritionists, psychologists, exercise specialists, teachers, and parents — can play a part in preventing weight gain during holidays.

 

Future Directions

The University of Sonora research team is currently conducting a controlled trial in Hermosillo, Mexico, involving adult participants divided into intervention and control groups. Preliminary results, already published online, highlight the effectiveness of strategies such as nutrition education, physical activity, regular weight goals, and psychological support in promoting habit changes.

“Interventions to prevent weight gain during the holidays and summer vacations are necessary,” the authors concluded, emphasizing the need for further research to evaluate their effectiveness in the region.

Haby de Sosa or Cristi-Montero declared no relevant financial conflicts of interest.

‘New Hope’ for Alcohol Use Disorder Treatment

Article Type
Changed
Fri, 12/20/2024 - 09:52

Evidence is mounting that new therapies already used to treat gut diseases, type 2 diabetes, and obesity may help people with alcohol use disorder (AUD).

Glucagon-like peptide 1 (GLP-1) receptor agonists, first used to treat diabetes and now widely used for weight loss, and fecal microbiota transplants (FMTs), used to treat diseases such as recurrent Clostridioides difficile infection, are advancing in clinical trials as potential options for treating AUD.

 

AUD Affects 28.9 Million People in the United States

In 2023, 28.9 million people aged 12 years or older in the United States had AUD (10.2% of the people in this age group). The Food and Drug Administration (FDA) has approved three medical therapiesAcamprosate, naltrexone, and disulfiram to help keep people with the disorder from returning to heavy drinking. Acamprosate’s mechanism of action is not clear, but it is thought to modulate and normalize alcohol-related changes in brain activity, thereby reducing withdrawal symptoms. Naltrexone blocks opioid receptors to reduce alcohol cravings. Disulfiram causes a toxic physical reaction when mixed with alcohol.

Some with AUD also benefit from behavioral therapies and support groups such as Alcoholics Anonymous. But for others, nothing has worked, and that’s part of the reason Lorenzo Leggio, MD, PhD, a scientist in the field of alcohol addiction with the National Institutes of Health (NIH), told this news organization that this is the “most exciting moment” for AUD treatment in his more than 2 decades of research in this area.

 

GLP-1 Agonists Showing Consistent Results

GLP-1 receptor agonists work by modulating the brain’s reward pathways, including the areas that regulate cravings and motivation.

“By dampening the reward signals associated with alcohol consumption, GLP-1 agonists may reduce cravings and heavy drinking episodes,” Fares Qeadan, PhD, MS, associate professor of biostatistics in the Department of Public Health Sciences at Loyola University Chicago in Illinois, told this news organization.

“The unique aspect of GLP-1 agonists is their ability to target both metabolic and reward systems in the brain,” he said. While naltrexone or acamprosate blocks the effects of alcohol or reduces withdrawal symptoms, “GLP-1 agonists approach addiction through a broader mechanism, potentially addressing underlying factors that contribute to cravings and compulsive behaviors,” he said.

As part of a study published in October in Addiction, Qeadan’s team found that people with AUD who were prescribed GLP-1 agonists had a 50% lower rate of severe intoxication than those who were not prescribed those medications.

“While this is observational and not yet definitive, it highlights the potential of these drugs to complement existing treatments for AUD,” he said.

Another study, a nationwide cohort study published in JAMA Psychiatry, found that using the GLP-1 receptor agonists semaglutide and liraglutide was linked to a lower risk for AUD-related hospitalizations than traditional AUD medications.

A systematic review, published last month in eClinical Medicine, concluded that, though there is little high-quality evidence demonstrating the effect of GLP-1 receptor agonists on alcohol use, “subgroup analysis from two [randomized, controlled trials] and supporting data from four observational studies suggest that GLP-1 [receptor agonists] may reduce alcohol consumption and improve outcomes in some individuals.”

Studying individual differences in response may have implications for personalized medicine, Qeadan said, as treatments could be tailored to those most likely to benefit, such as people with both metabolic dysfunction and AUD.

“These medications may offer hope for patients who struggle with addiction and have not responded to traditional therapies,” Qeadan said.

 

Exploring FMT as AUD Treatment

FMT is also a new research focus for treating AUD. Jasmohan Bajaj, MD, a gastroenterologist and liver specialist at Virginia Commonwealth University Medical Center, Richmond, is leading the Intestinal Microbiota Transplant in Alcohol-Associated Liver Disease (IMPACT) trial.

AUD has been linked with gut microbial alterations that worsen with cirrhosis. Research has shown that alcohol consumption changes the diversity of bacteria and can lead to bacterial overgrowth and progression of alcohol-associated liver disease.

FMT has been effective in rebalancing gut bacteria by transferring healthy stool from screened donors into patients who have developed an overgrowth of harmful bacteria. In the IMPACT trial, participants, who have not previously received traditional treatment for AUD or for whom treatment has not worked, are randomized either to the oral treatment capsule, which contains freeze-dried stool from a donor with healthy gut bacteria, or placebo.

The trial, sponsored by the NIH, is halfway through its target enrollment of 80.

In a previous smaller, placebo-controlled, phase 1 study, also led by Bajaj and published in Hepatology, 9 of the 10 volunteers who had severe AUD and cirrhosis experienced fewer alcohol cravings and had lower consumption after 15 days. Only three of the placebo participants saw similar improvements. Those who received the microbiota transplant also had fewer AUD-related events over 6 months.

Bajaj said that, if trials show FMT is safe and effective, he envisions the treatment as one tool in a multidisciplinary, integrated clinic that would include a hepatologist and mental health clinicians.

One benefit of the FMT treatment approach is it is given once or twice only, rather than administered regularly.

 

Current Treatments Work, But More are Needed

Leggio, who is clinical director of the National Institute on Drug Abuse Intramural Research Program, said: “We know that alcohol use disorder, and addiction in general, is a brain disease. We also know that the brain does not work in isolation. The brain is constantly interacting with the rest of the body, including with the gut.”

Leggio said it’s important to note that the three FDA-approved medications do work for alcohol addiction. He said they work as well as selective serotonin reuptake inhibitors for depression and beta-blockers for chronic heart failure.

But there are only three, and they don’t work for everyone, he noted. Those are among the reasons developing new treatments is important. New treatments could be used as an alternative or in combination with already approved treatments.

FMT is in “the very early stages” of trials testing its use for AUD, Leggio noted, adding that the studies by Bajaj’s team are among the very few addressing gut dysbiosis in AUD, and all have involved small numbers of patients. “It’s promising. It’s intriguing. It’s exciting. But we are just at the beginning.”

 

Results Consistent Across Species, Labs

GLP-1 agonists are further along in trials but still not ready for prescribing for AUD, Leggio said. The positive results have been consistent across species, different labs, and different research teams around the world.

Researchers have also explored through electronic health record emulation trials whether people already taking GLP-1 agonists for diabetes or obesity drink less alcohol compared with matched cohorts not taking GLP-1s. “They consistently show that the people who are on GLP-1s drink less,” he said.

“[Emulation trials] don’t replace the need for randomized controlled trials, Leggio noted. Leggio’s team is currently working on a randomized, placebo-controlled, double-blinded trial studying GLP-1s in relation to AUD.

 

New Directions 20-Year Highlight

This whole line of research represents “new hope” and has many implications, Leggio said. “I have been in this business for 20-plus years, and I think this is themost exciting moment when we have a very promising target in GLP-1s.”

Regardless of efficacy, he said, the focus on GLP-1 agonists and FMT for AUD has people talking more about addiction and the brain-body connection rather than assuming AUD is a result of poor choices and “bad behavior.”

The momentum of new treatments could also lead to patients and physicians having conversations about existing treatments.

“Hopefully, this momentum will help us destigmatize addiction, and by destigmatizing addiction, there will be an uptick in use of currently approved medications,” Leggio said.

Qeadan, Bajaj, and Leggio reported no relevant financial relationships.

The momentum of new treatments could also lead to patients and physicians having conversations about existing treatments.

“Hopefully, this momentum will help us destigmatize addiction, and by destigmatizing addiction, there will be an uptick in use of currently approved medications,” Leggio said.

Evidence is mounting that new therapies already used to treat gut diseases, type 2 diabetes, and obesity may help people with alcohol use disorder (AUD).

Glucagon-like peptide 1 (GLP-1) receptor agonists, first used to treat diabetes and now widely used for weight loss, and fecal microbiota transplants (FMTs), used to treat diseases such as recurrent Clostridioides difficile infection, are advancing in clinical trials as potential options for treating AUD.

 

AUD Affects 28.9 Million People in the United States

In 2023, 28.9 million people aged 12 years or older in the United States had AUD (10.2% of the people in this age group). The Food and Drug Administration (FDA) has approved three medical therapiesAcamprosate, naltrexone, and disulfiram to help keep people with the disorder from returning to heavy drinking. Acamprosate’s mechanism of action is not clear, but it is thought to modulate and normalize alcohol-related changes in brain activity, thereby reducing withdrawal symptoms. Naltrexone blocks opioid receptors to reduce alcohol cravings. Disulfiram causes a toxic physical reaction when mixed with alcohol.

Some with AUD also benefit from behavioral therapies and support groups such as Alcoholics Anonymous. But for others, nothing has worked, and that’s part of the reason Lorenzo Leggio, MD, PhD, a scientist in the field of alcohol addiction with the National Institutes of Health (NIH), told this news organization that this is the “most exciting moment” for AUD treatment in his more than 2 decades of research in this area.

 

GLP-1 Agonists Showing Consistent Results

GLP-1 receptor agonists work by modulating the brain’s reward pathways, including the areas that regulate cravings and motivation.

“By dampening the reward signals associated with alcohol consumption, GLP-1 agonists may reduce cravings and heavy drinking episodes,” Fares Qeadan, PhD, MS, associate professor of biostatistics in the Department of Public Health Sciences at Loyola University Chicago in Illinois, told this news organization.

“The unique aspect of GLP-1 agonists is their ability to target both metabolic and reward systems in the brain,” he said. While naltrexone or acamprosate blocks the effects of alcohol or reduces withdrawal symptoms, “GLP-1 agonists approach addiction through a broader mechanism, potentially addressing underlying factors that contribute to cravings and compulsive behaviors,” he said.

As part of a study published in October in Addiction, Qeadan’s team found that people with AUD who were prescribed GLP-1 agonists had a 50% lower rate of severe intoxication than those who were not prescribed those medications.

“While this is observational and not yet definitive, it highlights the potential of these drugs to complement existing treatments for AUD,” he said.

Another study, a nationwide cohort study published in JAMA Psychiatry, found that using the GLP-1 receptor agonists semaglutide and liraglutide was linked to a lower risk for AUD-related hospitalizations than traditional AUD medications.

A systematic review, published last month in eClinical Medicine, concluded that, though there is little high-quality evidence demonstrating the effect of GLP-1 receptor agonists on alcohol use, “subgroup analysis from two [randomized, controlled trials] and supporting data from four observational studies suggest that GLP-1 [receptor agonists] may reduce alcohol consumption and improve outcomes in some individuals.”

Studying individual differences in response may have implications for personalized medicine, Qeadan said, as treatments could be tailored to those most likely to benefit, such as people with both metabolic dysfunction and AUD.

“These medications may offer hope for patients who struggle with addiction and have not responded to traditional therapies,” Qeadan said.

 

Exploring FMT as AUD Treatment

FMT is also a new research focus for treating AUD. Jasmohan Bajaj, MD, a gastroenterologist and liver specialist at Virginia Commonwealth University Medical Center, Richmond, is leading the Intestinal Microbiota Transplant in Alcohol-Associated Liver Disease (IMPACT) trial.

AUD has been linked with gut microbial alterations that worsen with cirrhosis. Research has shown that alcohol consumption changes the diversity of bacteria and can lead to bacterial overgrowth and progression of alcohol-associated liver disease.

FMT has been effective in rebalancing gut bacteria by transferring healthy stool from screened donors into patients who have developed an overgrowth of harmful bacteria. In the IMPACT trial, participants, who have not previously received traditional treatment for AUD or for whom treatment has not worked, are randomized either to the oral treatment capsule, which contains freeze-dried stool from a donor with healthy gut bacteria, or placebo.

The trial, sponsored by the NIH, is halfway through its target enrollment of 80.

In a previous smaller, placebo-controlled, phase 1 study, also led by Bajaj and published in Hepatology, 9 of the 10 volunteers who had severe AUD and cirrhosis experienced fewer alcohol cravings and had lower consumption after 15 days. Only three of the placebo participants saw similar improvements. Those who received the microbiota transplant also had fewer AUD-related events over 6 months.

Bajaj said that, if trials show FMT is safe and effective, he envisions the treatment as one tool in a multidisciplinary, integrated clinic that would include a hepatologist and mental health clinicians.

One benefit of the FMT treatment approach is it is given once or twice only, rather than administered regularly.

 

Current Treatments Work, But More are Needed

Leggio, who is clinical director of the National Institute on Drug Abuse Intramural Research Program, said: “We know that alcohol use disorder, and addiction in general, is a brain disease. We also know that the brain does not work in isolation. The brain is constantly interacting with the rest of the body, including with the gut.”

Leggio said it’s important to note that the three FDA-approved medications do work for alcohol addiction. He said they work as well as selective serotonin reuptake inhibitors for depression and beta-blockers for chronic heart failure.

But there are only three, and they don’t work for everyone, he noted. Those are among the reasons developing new treatments is important. New treatments could be used as an alternative or in combination with already approved treatments.

FMT is in “the very early stages” of trials testing its use for AUD, Leggio noted, adding that the studies by Bajaj’s team are among the very few addressing gut dysbiosis in AUD, and all have involved small numbers of patients. “It’s promising. It’s intriguing. It’s exciting. But we are just at the beginning.”

 

Results Consistent Across Species, Labs

GLP-1 agonists are further along in trials but still not ready for prescribing for AUD, Leggio said. The positive results have been consistent across species, different labs, and different research teams around the world.

Researchers have also explored through electronic health record emulation trials whether people already taking GLP-1 agonists for diabetes or obesity drink less alcohol compared with matched cohorts not taking GLP-1s. “They consistently show that the people who are on GLP-1s drink less,” he said.

“[Emulation trials] don’t replace the need for randomized controlled trials, Leggio noted. Leggio’s team is currently working on a randomized, placebo-controlled, double-blinded trial studying GLP-1s in relation to AUD.

 

New Directions 20-Year Highlight

This whole line of research represents “new hope” and has many implications, Leggio said. “I have been in this business for 20-plus years, and I think this is themost exciting moment when we have a very promising target in GLP-1s.”

Regardless of efficacy, he said, the focus on GLP-1 agonists and FMT for AUD has people talking more about addiction and the brain-body connection rather than assuming AUD is a result of poor choices and “bad behavior.”

The momentum of new treatments could also lead to patients and physicians having conversations about existing treatments.

“Hopefully, this momentum will help us destigmatize addiction, and by destigmatizing addiction, there will be an uptick in use of currently approved medications,” Leggio said.

What’s the Best Way to Combat Diet Fatigue?

Article Type
Changed
Wed, 12/18/2024 - 16:54

Every year, an estimated 45 million Americans attempt some kind of diet to shed weight, especially after the holidays. Whether or not an individual is on a successful weight loss journey, at some point they probably will experience “diet fatigue.” This is the mental and emotional exhaustion associated with engaging in dieting behaviors like calorie counting, weighing and measuring food, meal planning and prepping, and restricting certain foods. 

Diet fatigue is a huge reason (but certainly not the only reason) why diets fail, as dieters can become so burned out that they ditch their diet, return to their former eating habits, blame themselves for their diet failure, and then repeat the cycle.

Alison* became my client just as her diet fatigue was starting to settle in. She had already lost 25 pounds in the prior 6 months while in a coaching program that focused primarily on hitting calorie and macro targets. She had been following an extremely high-protein regimen that relied heavily on animal sources and protein powders. I’m not against using powders to supplement protein needs, but in Alison’s case, she was consuming a powder-and-milk concoction twice per day in place of a meal with actual food. Not only had she become plain sick of the powder, but she was also concerned that all the protein was pushing vegetables off her plate. Alison had been following this plan quite strictly but admitted to indulging in weekend sweets. She recognized that this occasional indulgence could quickly morph into a full-on habit and undo her progress. While Alison had not yet reached her goal weight, we both agreed that she needed to change up her eating routine. 

Getting a patient through diet fatigue involves identifying which dieting behaviors are causing them the most angst and then guiding them toward a more sustainable approach that provides a similar benefit. For example, many dieters develop a huge disdain for calorie tracking, which they most often describe as tedious. One alternative to tracking calories is food journaling, which encourages accountability and mindfulness but is not as time-consuming as plugging every single ingredient you ingest into an app. Alison, however, didn’t have a problem with tracking, nor with weighing her food (as a Type A personality, she preferred having this kind of control). But she was clearly lacking a few things in her previous diet: variety, fiber, and flavor. In short, Alison was not enjoying her food — hence, her increased desire for treats on weekends, which she saw as a kind of reward for “being good” all week. 

To keep Alison from slipping into a weekend bingeing pattern, we discussed a few tweaks to her regimen. First, we had to ditch the protein powder in favor of balanced meals. I recommended reducing her daily protein target, which I felt was unnecessarily high. This provided some wiggle room to add a well-rounded dinner. I encouraged her to start adding spices and herbs to make dishes more exciting. 

Finally — and this one might be controversial — I encouraged Alison to actually plan for a weekly indulgence. In my experience working in the weight management space, complete restriction of a desired food always backfires, so it made sense for Alison to simply build the chocolate into her plan in a reasonable way. 

I’m confident that Alison will reach her weight loss goal (and keep the weight off) if food continues to bring her pleasure. When it comes to weight loss, I believe that if the solution is temporary, success will also be temporary. As a dietitian, preaching sustainable, long-term habit changes is my priority, not just because it’s responsible, but because it’s the only approach that truly works.

A New Weight Loss Drug With No Side Effects? Yes... So Far

Article Type
Changed
Thu, 12/19/2024 - 06:04

For people with obesity or type 2 diabetes, glucagon-like peptide 1 (GLP-1) agonists (including Mounjaro, Wegovy, and Ozempic) have been labeled miracle drugs. But they aren’t miraculous for everyone. Research indicates a significant portion of people discontinue using them within a year.

The main problems with GLP-1 agonists are that they are expensive and have a fairly high rate of side effects — such as nausea, vomiting, diarrhea, or constipation. Another big one is muscle loss.

A new study, published in Nature, shows a potential alternative to GLP-1 agonists with fewer side effects, at least in mice and nonhuman primates.

This lack of side effects, particularly in how the potential drug causes no muscle loss — and in fact engages muscle for some of its effect — sets it apart and makes it a potential alternative to GLP-1s. The key is not just reducing appetite but also increasing energy expenditure.

 

How It Works

The new approach targets a protein called NK2R — a member of the neurokinin receptor family, which has a role in a variety of physiological processes, including pain sensation, anxiety, and inflammation. 

“We were looking to see genetic linkages to metabolic health, and there NK2R was,” said Zach Gerhart-Hines, PhD, a professor studying molecular metabolism at the University of Copenhagen in Denmark and principal investigator of the study. The group then created a few long-acting agonists that are selective for NK2R. So far, they’ve tested them in mice and nonhuman primates.

“The data on new medicines targeting NK2R is very promising and highlights the potential of both reducing food intake and increasing energy expenditure,” said Daniel Drucker, MD, an endocrinologist and researcher at Lunenfeld-Tanenbaum Research Institute in Toronto who was not involved in the study.

“The drug activates a certain region in the hindbrain of the animal, which is controlling food intake, and it does so by reducing appetite without increasing nausea or vomiting,” explained Frederike Sass, a research assistant at the University of Copenhagen in Copenhagen, Denmark, who led the study.

Gerhart-Hines said that even at the highest dose, there were no incidents of vomiting among the nonhuman primates. Mice can’t vomit, but there are ways to tell if they feel unwell from a drug. One way researchers test that is to start feeding the mice sweetened water at the same time they’re given a drug. Then later, when the mice are no longer on the drug, they’re given a choice between sweetened and unsweetened water. If they weren’t feeling well on the drug, they’ll choose plain water because they associate the sweet water with feeling bad, otherwise mice prefer sweet water. Sass said that with the NK2R agonist, they continued to drink sweet water after the treatment, whereas when they gave the mice semaglutide, the mice preferred plain water posttreatment.

The researchers also monitored the animals’ psychological health, as NK2R has been associated with anxiety, but they observed no behavioral changes.

 

The Key Mechanism at Work

One big question is how the NK2R agonists work. The amphetamines people used for weight loss during the 1950s and 1960s worked by making people more active. GLP-1 agonists reduce appetite and lower blood sugar. This is not that. In their studies with animals, the researchers didn’t observe that the animals were more active nor were there changes in other biomarkers like insulin. So far, the main difference they found with the NK2R agonists is an increase in thermogenesis in certain muscles.

Another benefit of the NK2R treatments is that they don’t seem to have a big impact on lean mass — the nonfat component of body weight, namely muscle, bones, and organs. Studies indicate that 25%-39% of weight loss on GLP-1 agonists is lost muscle. According to DEXA scans of the mice, Gerhart-Hines said they observed no lean mass loss. (In mice, he noted, GLP-1 agonists can cause up to 50% lean mass loss).

And for people with both diabetes and obesity, “what we found with NK2R is that obese and diabetic models, whether mice or monkeys, respond much better to that treatment in terms of glucose control and body weight loss,” Gerhart-Hines said. He explained that GLP-1 agonists don’t work quite as well for weight loss in people with diabetes because the drug stimulates insulin production in a system that already has insulin issues and can cause more sugar to be stored as fat.

Further, GLP-1 agonists are peptide drugs, which are expensive to make. The NK2R agonists are small molecules that would be cheaper to produce, Gerhart-Hines believes. One candidate they’re testing would likely be given once daily, another once weekly.

The current surge in obesity and diabetes may be a direct consequence of our bodies’ decreased energy expenditure. “Compared to 80s and 90s, the average person is more physically active, but the overarching basal resting energy expenditure has gone down,” said Gerhart-Hines, according to research by John Speakman at the University of Aberdeen, Scotland. We don’t know why, though, he said, but guesses it could be our diets or climate controlled environments.

But the NK2R agonists are among the many currently being studied for weight loss, and it may be hard to compete with the GLP-1 agonists. “As GLP-1 medicines will soon achieve 25% weight loss and have an extensively studied safety profile, the task of producing better drugs that work well in most people, are well tolerated and also reduce the complications of cardiometabolic disease, is challenging but not impossible,” said Drucker.

Gerhart-Hines said they plan to start trials in humans in the next year, but he suspects it will be another 6 or 7 years before it comes to market, if the trials are successful.

“There’s people who want [a GLP-1 agonist] and can’t even get it,” Gerhart-Hines said. As far as weight loss drugs, he noted, “we are not even saturating the market right now.”

“The data on new medicines targeting NK2R is very promising and highlights the potential of both reducing food intake and increasing energy expenditure,” said Daniel Drucker, MD, an endocrinologist and researcher at Lunenfeld-Tanenbaum Research Institute in Toronto who was not involved in the study.

“The drug activates a certain region in the hindbrain of the animal, which is controlling food intake, and it does so by reducing appetite without increasing nausea or vomiting,” explained Frederike Sass, a research assistant at the University of Copenhagen in Copenhagen, Denmark, who led the study.

Gerhart-Hines said that even at the highest dose, there were no incidents of vomiting among the nonhuman primates. Mice can’t vomit, but there are ways to tell if they feel unwell from a drug. One way researchers test that is to start feeding the mice sweetened water at the same time they’re given a drug. Then later, when the mice are no longer on the drug, they’re given a choice between sweetened and unsweetened water. If they weren’t feeling well on the drug, they’ll choose plain water because they associate the sweet water with feeling bad, otherwise mice prefer sweet water. Sass said that with the NK2R agonist, they continued to drink sweet water after the treatment, whereas when they gave the mice semaglutide, the mice preferred plain water posttreatment.

The researchers also monitored the animals’ psychological health, as NK2R has been associated with anxiety, but they observed no behavioral changes.

 

The Key Mechanism at Work

One big question is how the NK2R agonists work. The amphetamines people used for weight loss during the 1950s and 1960s worked by making people more active. GLP-1 agonists reduce appetite and lower blood sugar. This is not that. In their studies with animals, the researchers didn’t observe that the animals were more active nor were there changes in other biomarkers like insulin. So far, the main difference they found with the NK2R agonists is an increase in thermogenesis in certain muscles.

Another benefit of the NK2R treatments is that they don’t seem to have a big impact on lean mass — the nonfat component of body weight, namely muscle, bones, and organs. Studies indicate that 25%-39% of weight loss on GLP-1 agonists is lost muscle. According to DEXA scans of the mice, Gerhart-Hines said they observed no lean mass loss. (In mice, he noted, GLP-1 agonists can cause up to 50% lean mass loss).

And for people with both diabetes and obesity, “what we found with NK2R is that obese and diabetic models, whether mice or monkeys, respond much better to that treatment in terms of glucose control and body weight loss,” Gerhart-Hines said. He explained that GLP-1 agonists don’t work quite as well for weight loss in people with diabetes because the drug stimulates insulin production in a system that already has insulin issues and can cause more sugar to be stored as fat.

Further, GLP-1 agonists are peptide drugs, which are expensive to make. The NK2R agonists are small molecules that would be cheaper to produce, Gerhart-Hines believes. One candidate they’re testing would likely be given once daily, another once weekly.

The current surge in obesity and diabetes may be a direct consequence of our bodies’ decreased energy expenditure. “Compared to 80s and 90s, the average person is more physically active, but the overarching basal resting energy expenditure has gone down,” said Gerhart-Hines, according to research by John Speakman at the University of Aberdeen, Scotland. We don’t know why, though, he said, but guesses it could be our diets or climate controlled environments.

But the NK2R agonists are among the many currently being studied for weight loss, and it may be hard to compete with the GLP-1 agonists. “As GLP-1 medicines will soon achieve 25% weight loss and have an extensively studied safety profile, the task of producing better drugs that work well in most people, are well tolerated and also reduce the complications of cardiometabolic disease, is challenging but not impossible,” said Drucker.

Gerhart-Hines said they plan to start trials in humans in the next year, but he suspects it will be another 6 or 7 years before it comes to market, if the trials are successful.

“There’s people who want [a GLP-1 agonist] and can’t even get it,” Gerhart-Hines said. As far as weight loss drugs, he noted, “we are not even saturating the market right now.”

Diabetes Drugs and Eye Disease: These Protect, These Don’t

Article Type

Thu, 12/19/2024 - 06:05

TOPLINE:

Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) and fenofibrates are associated with a reduced risk for diabetic macular edema (DME) in patients with type 2 diabetes, while calcium channel blockers appear to increase the risk.

METHODOLOGY:

  • Researchers conducted a retrospective analysis of electronic medical records from the TriNetX health research network to evaluate how systemic medications, such as GLP-1 RAs, fenofibrates, thiazolidinediones, and calcium channel blockers, influence the risk of developing DME in patients with type 2 diabetes.
  • They included patients with a 5-year history of type 2 diabetes and an absence of DME at baseline.
  • The treatment group included patients who initiated treatment with calcium channel blockers (n = 107,193), GLP-1 RAs (n = 76,583), thiazolidinediones (n = 25,657), or fenofibrates (n = 18,606) after a diagnosis of diabetes. The control group received none of these medications within 1 year of being diagnosed with the condition.
  • The researchers used propensity score matching to balance baseline characteristics and comorbidities between both groups.
  • The primary outcome was the incidence of diagnoses of DME within a 2-year follow-up period after the initiation of systemic medications.

TAKEAWAY:

  • Patients treated with calcium channel blockers showed an increased risk for incident DME (hazard ratio [HR], 1.66; 95% CI, 1.54-1.78) compared with control individuals.
  • Treatment with GLP-1 RAs was associated with a reduced risk for DME (HR, 0.77; 95% CI, 0.70-0.85), as was treatment with fenofibrates (HR, 0.83; 95% CI, 0.68-0.98).
  • No significant difference in risk for DME was observed between patients taking thiazolidinediones and control individuals.

IN PRACTICE:

“We found a possible protective effect for GLP-1 RA medications and fenofibrate for DME and an adverse effect for calcium channel blockers with regard to the development of DME in patients” with type 2 diabetes, the authors wrote.

“Our preliminary data suggests a protective effect with regard to GLP-1 RA drugs and the development of DME. Clinical studies examining a potential therapeutic effect of GLP-1 RA drugs on DME do seem warranted. A single orally administered drug could conceivably lower blood sugar, reduce weight, offer cardiovascular protection, and treat DME” in patients with type 2 diabetes, they added.

 

SOURCE:

The study was led by Jawad Muayad, BS, of the School of Medicine at Texas A&M University, in Houston. It was published online on December 5, 2024, in Ophthalmology Retina.

LIMITATIONS:

The study was retrospective in nature. It relied on electronic medical records for the diagnosis of DME instead of directly assessing retinal images or measuring retinal thickness. Moreover, patients on certain medications may have been monitored more closely, potentially influencing the likelihood of a diagnosis of DME being recorded.

DISCLOSURES:

The study did not receive any funding support. One author disclosed receiving consulting fees from various institutions and pharmaceutical companies. The other authors reported no relevant conflicts of interest.

This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication. A version of this article first appeared on Medscape.com.

Obesity Medications: Could Coverage Offset Obesity Care Costs?

Article Type
Changed
Thu, 12/12/2024 - 16:58


The question may seem simple: Could paying for weight loss medications — especially the pricey glucagon-like peptide 1 receptor agonists (GLP-1s), tirzepatide (Zepbound) and semaglutide (Wegovy) — be more cost-effective than paying for obesity care and the complications of obesity, such as cardiovascular disease and diabetes?

It’s a question that’s getting an increased amount of attention.

And for good reason — more than two in five US adults have obesity, according to the Centers for Disease Control and Prevention, and costs to treat obesity, in 2019 dollars, approached $173 billion, including productivity losses. Adults with obesity have annual healthcare costs of $1861 more than those at healthier weights.

Among recent developments:

  • A proposed new rule, announced on November 26 by the Biden administration, expands coverage of anti-obesity medication for Americans who have Medicare and Medicaid. If it takes effect, an estimated 3.4 million Medicare recipients and about 4 million adult Medicaid enrollees could get access to the medications.
  • As Medicare coverage goes, private insurers often follow. Observers predict that if the Centers for Medicare & Medicaid Services (CMS) covers anti-obesity drugs, more private employers may soon do the same. Recently, however, some private plans have done the opposite and dropped coverage of the pricey GLP-1s, which can cost $1000 a month or more out-of-pocket, citing excess costs for their company.
  • Among the analyses about the value of weight loss on healthcare cost savings is a report published on December 5 in JAMA Network Open. Emory University experts looked at privately insured adults and adult Medicare beneficiaries with a body mass index (BMI) of ≥ 25 (classified as overweight). The conclusion: Projected annual savings from weight loss among US adults with obesity were substantial for both employee-based insurance and Medicare recipients.
  • Besides helping obesity and obesity-related conditions, access to GLP-1s could have a favorable effect on productivity, others claim. That’s one focus of a 5-year partnership between the University of Manchester in England, and Eli Lilly and Company. Called SURMOUNT-REAL UK, the study will evaluate the effectiveness of tirzepatide in weight loss, diabetes prevention, and prevention of obesity-related complications in adults with obesity. It also aims to look at changes in health-related quality of life with weight loss and with changes in employment status and sick days.

CMS Proposal

In a statement announcing the proposal for Medicare and Medicaid to offer weight loss drugs, the White House noted that “tens of millions of Americans struggle with obesity” but that currently Medicare only covers the anti-obesity medications for certain conditions such as diabetes. The new proposal would expand that access to those with obesity. As of August, just 13 states cover GLP-1s in Medicaid programs, and North Carolina was the latest to do so.

Organizations advocating for health equity and recognition that obesity is a chronic disease came out in strong support of the proposal.

Kenneth E. Thorpe, PhD, a health policy expert at Emory University in Atlanta, who coauthored the recent analysis finding that weight loss offsets healthcare costs on an individual basis, told this news organization: “If finalized, this broad new coverage [by Medicare and Medicaid] would have a profound impact on the ability of Americans to access these novel medications that could significantly reduce obesity-related healthcare spending and improve overall health.”

The proposal “is modernizing the coverage of Medicare and Medicaid for obesity treatment,” agreed John Cawley, PhD, professor of economics and public policy at Cornell University in Ithaca, New York, who has researched the direct medical costs of obesity in the United States. “In this HHS rule, they talk about the scientific and medical consensus that having obesity is a chronic condition.”

The proposal requires a 60-day comment period that ends January 27, 2025, taking the timeline into the beginning of the Trump administration. Cawley and others pointed out that Trump’s pick for Health and Human Services Secretary, Robert F. Kennedy Jr, has been an outspoken opponent of the anti-obesity medicines, suggesting instead that Americans simply eat better.

 

Expert Analyses: Emory, Cornell, Southern California

So would paying for the pricey GLP-1s be smart in the long term? Analyses don’t agree.

Weight loss among those with obesity produces healthcare cost savings, said Thorpe and Peter Joski, MSPH, an associate research professor at Emory University. The two compared annual healthcare spending among privately insured adults and adult Medicare beneficiaries with a BMI of ≥ 25, using data from the Medical Expenditure Panel Survey — Household Component from April 1 to June 20, 2024.

The researchers looked at 3774 adults insured with Medicare and 13,435 with employer-sponsored insurance. Overall, those with private insurance with a weight loss of 5% spent an estimated average of $670 less on healthcare. Those with a weight loss of 25% spent an estimated $2849 less on healthcare. Among those with Medicare who had one or more comorbidities, a 5% weight loss reduced spending by $1262 on average; a 25% loss reduced it by an estimated $5442, or 31%.

Thorpe called the savings substantial. In an email interview, Thorpe said, “So yes, weight loss for people living with obesity does lower healthcare costs, as my research shows, but it also lowers other costs as well.”

These include costs associated with disability, workers’ compensation, presenteeism/absenteeism, and everyday costs, he said. He contends that “those other costs should factor into decisions about preventing and treating obesity of payors and policymakers and enhance the case for cost-effectiveness of treating obesity.”

Other research suggests it’s important to target the use of the anti-obesity medications to the BMI range that would get the most benefit. For people just barely above the BMI threshold of 30, no cost savings are expected, Cawley found in his research. But he has found substantial cost reduction if the BMI was 35-40.

However, as Cawley pointed out, as the drugs get cheaper and more options become available, the entire scenario is expected to shift.

 

The Congressional Budget Office View

In October, the nonpartisan Congressional Budget Office issued a report, “How Would Authorizing Medicare to Cover Anti-Obesity Medications Affect the Federal Budget?” Among the conclusions: Covering the anti-obesity medications would increase federal spending, on net, by about $35 billion from 2026 to 2034. Total direct federal costs of covering the medication would increase from $1.6 billion in 2026 to $7.1 billion in 2034. And it said total savings from improved health of the beneficiaries would be small, less than $50 million in 2026 and rising to $1 billion in 2034.

Covering the medications would cost $5600 per user in 2026, then down to $4300 in 2034. The offset of savings per user would be about $50 in 2026, then $650 in 2034.

 

Expert Analysis: USC Schaeffer Center

“The costs offsets come over time,” said Alison Sexton Ward, PhD, an economist at the University of Southern California’s Leonard D. Schaeffer Center, Los Angeles, and an expert on the topic. “If we look at the average annual medical cost over a lifetime, we do see cost offsets there.”

However, treating obesity means people will live longer, “and living longer costs more,” she said.

She took issue with some of the calculations in the CBO report, such as not considering the effect of semaglutide’s patent expiring in 2033.

In a white paper published in April 2023, Sexton Ward and her coauthors modeled potential social benefits and medical cost offsets from granting access to the newer weight loss drugs. The cumulative social benefits of providing coverage over the next decade would reach nearly $1 trillion, they said. Benefits would increase if private insurance expanded coverage. “In the first 10 years alone, covering weight loss therapies would save Medicare $175 billion-$245 billion, depending on whether private insurance joins Medicare in providing coverage for younger populations.”

While much focus is on Medicare coverage, Sexton Ward and others pointed out the need to expand coverage to younger ages, with the aim of preventing or delaying obesity-related complications.

 

Lilly UK Trial

A spokesperson for Lilly declined to comment further on the UK study, explaining that the study was just launching.

Besides tracking weight loss, researchers will evaluate the effect of the weight loss on sick days from work and employment. Obesity is shown to affect a person’s ability to work, leading to more absenteeism, so treating the obesity may improve productivity.

 

Beyond Health: The Value of Weight Loss

“I love the idea of studying whether access to obesity medications helps people stay employed and do their job,” said Cristy Gallagher, associate director of Research and Policy at STOP Obesity Alliance at the Milken Institute School of Public Health, George Washington University, Washington, DC. The alliance includes more than 50 organizations advocating for adult obesity treatment.

“One of our big arguments is [that] access to care, and to obesity care, will also help other conditions — comorbidities like heart disease and diabetes.”

However, access to the anti-obesity medications, by itself, is not enough, Gallagher said. Other components, such as intensive behavioral therapy and guidance about diet and exercise, are needed, she said. So, too, for those who need it, is access to bariatric surgery, she said. And medication access should include other options besides the GLP-1s, she said. “Not every medication is right for everybody.”

Cawley, Gallagher, Thorpe, and Sexton Ward had no disclosures.

In a white paper published in April 2023, Sexton Ward and her coauthors modeled potential social benefits and medical cost offsets from granting access to the newer weight loss drugs. The cumulative social benefits of providing coverage over the next decade would reach nearly $1 trillion, they said. Benefits would increase if private insurance expanded coverage. “In the first 10 years alone, covering weight loss therapies would save Medicare $175 billion-$245 billion, depending on whether private insurance joins Medicare in providing coverage for younger populations.”

While much focus is on Medicare coverage, Sexton Ward and others pointed out the need to expand coverage to younger ages, with the aim of preventing or delaying obesity-related complications.

 

Lilly UK Trial

A spokesperson for Lilly declined to comment further on the UK study, explaining that the study was just launching.

Besides tracking weight loss, researchers will evaluate the effect of the weight loss on sick days from work and employment. Obesity is shown to affect a person’s ability to work, leading to more absenteeism, so treating the obesity may improve productivity.

 

Beyond Health: The Value of Weight Loss

“I love the idea of studying whether access to obesity medications helps people stay employed and do their job,” said Cristy Gallagher, associate director of Research and Policy at STOP Obesity Alliance at the Milken Institute School of Public Health, George Washington University, Washington, DC. The alliance includes more than 50 organizations advocating for adult obesity treatment.

“One of our big arguments is [that] access to care, and to obesity care, will also help other conditions — comorbidities like heart disease and diabetes.”

However, access to the anti-obesity medications, by itself, is not enough, Gallagher said. Other components, such as intensive behavioral therapy and guidance about diet and exercise, are needed, she said. So, too, for those who need it, is access to bariatric surgery, she said. And medication access should include other options besides the GLP-1s, she said. “Not every medication is right for everybody.”

Cawley, Gallagher, Thorpe, and Sexton Ward had no disclosures.

The question may seem simple: Could paying for weight loss medications — especially the pricey glucagon-like peptide 1 receptor agonists (GLP-1s), tirzepatide (Zepbound) and semaglutide (Wegovy) — be more cost-effective than paying for obesity care and the complications of obesity, such as cardiovascular disease and diabetes?

It’s a question that’s getting an increased amount of attention.

And for good reason — more than two in five US adults have obesity, according to the Centers for Disease Control and Prevention, and costs to treat obesity, in 2019 dollars, approached $173 billion, including productivity losses. Adults with obesity have annual healthcare costs of $1861 more than those at healthier weights.

Among recent developments:

  • A proposed new rule, announced on November 26 by the Biden administration, expands coverage of anti-obesity medication for Americans who have Medicare and Medicaid. If it takes effect, an estimated 3.4 million Medicare recipients and about 4 million adult Medicaid enrollees could get access to the medications.
  • As Medicare coverage goes, private insurers often follow. Observers predict that if the Centers for Medicare & Medicaid Services (CMS) covers anti-obesity drugs, more private employers may soon do the same. Recently, however, some private plans have done the opposite and dropped coverage of the pricey GLP-1s, which can cost $1000 a month or more out-of-pocket, citing excess costs for their company.
  • Among the analyses about the value of weight loss on healthcare cost savings is a report published on December 5 in JAMA Network Open. Emory University experts looked at privately insured adults and adult Medicare beneficiaries with a body mass index (BMI) of ≥ 25 (classified as overweight). The conclusion: Projected annual savings from weight loss among US adults with obesity were substantial for both employee-based insurance and Medicare recipients.
  • Besides helping obesity and obesity-related conditions, access to GLP-1s could have a favorable effect on productivity, others claim. That’s one focus of a 5-year partnership between the University of Manchester in England, and Eli Lilly and Company. Called SURMOUNT-REAL UK, the study will evaluate the effectiveness of tirzepatide in weight loss, diabetes prevention, and prevention of obesity-related complications in adults with obesity. It also aims to look at changes in health-related quality of life with weight loss and with changes in employment status and sick days.

CMS Proposal

In a statement announcing the proposal for Medicare and Medicaid to offer weight loss drugs, the White House noted that “tens of millions of Americans struggle with obesity” but that currently Medicare only covers the anti-obesity medications for certain conditions such as diabetes. The new proposal would expand that access to those with obesity. As of August, just 13 states cover GLP-1s in Medicaid programs, and North Carolina was the latest to do so.

Organizations advocating for health equity and recognition that obesity is a chronic disease came out in strong support of the proposal.

Kenneth E. Thorpe, PhD, a health policy expert at Emory University in Atlanta, who coauthored the recent analysis finding that weight loss offsets healthcare costs on an individual basis, told this news organization: “If finalized, this broad new coverage [by Medicare and Medicaid] would have a profound impact on the ability of Americans to access these novel medications that could significantly reduce obesity-related healthcare spending and improve overall health.”

The proposal “is modernizing the coverage of Medicare and Medicaid for obesity treatment,” agreed John Cawley, PhD, professor of economics and public policy at Cornell University in Ithaca, New York, who has researched the direct medical costs of obesity in the United States. “In this HHS rule, they talk about the scientific and medical consensus that having obesity is a chronic condition.”

The proposal requires a 60-day comment period that ends January 27, 2025, taking the timeline into the beginning of the Trump administration. Cawley and others pointed out that Trump’s pick for Health and Human Services Secretary, Robert F. Kennedy Jr, has been an outspoken opponent of the anti-obesity medicines, suggesting instead that Americans simply eat better.

 

Expert Analyses: Emory, Cornell, Southern California

So would paying for the pricey GLP-1s be smart in the long term? Analyses don’t agree.

Weight loss among those with obesity produces healthcare cost savings, said Thorpe and Peter Joski, MSPH, an associate research professor at Emory University. The two compared annual healthcare spending among privately insured adults and adult Medicare beneficiaries with a BMI of ≥ 25, using data from the Medical Expenditure Panel Survey — Household Component from April 1 to June 20, 2024.

The researchers looked at 3774 adults insured with Medicare and 13,435 with employer-sponsored insurance. Overall, those with private insurance with a weight loss of 5% spent an estimated average of $670 less on healthcare. Those with a weight loss of 25% spent an estimated $2849 less on healthcare. Among those with Medicare who had one or more comorbidities, a 5% weight loss reduced spending by $1262 on average; a 25% loss reduced it by an estimated $5442, or 31%.

Thorpe called the savings substantial. In an email interview, Thorpe said, “So yes, weight loss for people living with obesity does lower healthcare costs, as my research shows, but it also lowers other costs as well.”

These include costs associated with disability, workers’ compensation, presenteeism/absenteeism, and everyday costs, he said. He contends that “those other costs should factor into decisions about preventing and treating obesity of payors and policymakers and enhance the case for cost-effectiveness of treating obesity.”

Other research suggests it’s important to target the use of the anti-obesity medications to the BMI range that would get the most benefit. For people just barely above the BMI threshold of 30, no cost savings are expected, Cawley found in his research. But he has found substantial cost reduction if the BMI was 35-40.

However, as Cawley pointed out, as the drugs get cheaper and more options become available, the entire scenario is expected to shift.

 

The Congressional Budget Office View

In October, the nonpartisan Congressional Budget Office issued a report, “How Would Authorizing Medicare to Cover Anti-Obesity Medications Affect the Federal Budget?” Among the conclusions: Covering the anti-obesity medications would increase federal spending, on net, by about $35 billion from 2026 to 2034. Total direct federal costs of covering the medication would increase from $1.6 billion in 2026 to $7.1 billion in 2034. And it said total savings from improved health of the beneficiaries would be small, less than $50 million in 2026 and rising to $1 billion in 2034.

Covering the medications would cost $5600 per user in 2026, then down to $4300 in 2034. The offset of savings per user would be about $50 in 2026, then $650 in 2034.

 

Expert Analysis: USC Schaeffer Center

“The costs offsets come over time,” said Alison Sexton Ward, PhD, an economist at the University of Southern California’s Leonard D. Schaeffer Center, Los Angeles, and an expert on the topic. “If we look at the average annual medical cost over a lifetime, we do see cost offsets there.”

However, treating obesity means people will live longer, “and living longer costs more,” she said.

She took issue with some of the calculations in the CBO report, such as not considering the effect of semaglutide’s patent expiring in 2033.

In a white paper published in April 2023, Sexton Ward and her coauthors modeled potential social benefits and medical cost offsets from granting access to the newer weight loss drugs.

Bariatric Surgery Better Than Obesity Drugs for Some Patients With MASLD

Article Type
Changed
Thu, 12/12/2024 - 16:19

In patients with metabolic dysfunction–associated steatotic liver disease (MASLD), bariatric surgery appears to carry a lower risk for mortality after 5 years than treatment with pharmacologic therapies such as glucagon-like peptide 1 (GLP-1) receptor agonists or sodium-glucose cotransporter 2 (SGLT2) inhibitors, new study results showed.

In a separate analysis of data from the same study, researchers also found that bariatric surgery alone had lower risks for major adverse cardiovascular events (MACEs) than GLP-1 or SGLT2 inhibitor use or a combination of surgery and medications.

“While weight loss medications have demonstrated notable success, especially in managing diabetes and aiding weight loss, bariatric surgery offers more significant and varied benefits for weight and metabolic health, making it a better option for some patients,” said Leith Ghani, DO, an internal medicine resident at The University of Arizona College of Medicine – Phoenix.

Ghani presented the findings about mortality at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD). His co-author and fellow internal medicine resident Qumber Ali, DO, presented the findings about MACEs.

These findings highlight “the need for personalized treatment plans, allowing the decision between surgery and medication to be customized according to each patient’s specific situation and health goals,” Ghani said. “It also emphasizes the importance of a multidisciplinary approach to patient management.”

 

Comparing Bariatric Interventions and Pharmacologic Treatments

The retrospective, multicenter study of hospital admissions data from the Banner Health system in Phoenix included more than 8600 patients who had MASLD-related diagnostic codes and metabolic criteria. Patients were divided into four groups according to the treatment they received: Bariatric surgery alone (5.8%), GLP-1 medications (39.3%), SGLT2 inhibitor medications (23.4%), or a combination of surgery and medications (31.5%).

In the mortality analysis, Ghani and colleagues looked at data for patients who died between 12 and 60 months after surgery or starting medication. They found that patients who underwent bariatric surgery had a significantly higher chance of survival at 5 years.

When compared to bariatric surgery, the adjusted hazard ratio (aHR) for GLP-1 medications was 2.99, followed by an aHR of 2.96 for SGLT2 inhibitor medications, and an aHR of 1.78 for a combination of treatments.

In the MACE analysis, Ali and colleagues looked at data for patients who were followed for 12 months or more after intervention or initiation of treatment, identifying MACE diagnostic codes for coronary artery disease, cerebrovascular disease, and congestive heart failure. They found that patients who underwent bariatric surgery alone had a significantly lower rate of MACEs.

When compared to bariatric surgery, the aHR was 1.83 for GLP-1 medications, 1.72 for SGLT2 inhibitor medications, and 1.91 for a combination of treatments.

Regarding both analyses, patients taking GLP-1 or SGLT2 inhibitor medications may face higher risks for mortality or serious heart problems due to existing metabolic disorders or heart disease, Ali said.

Future studies could look at other risk factors that make these patients more vulnerable, he added. For instance, factors related to body mass index, glucose control, other medications, different clinical settings, and race/ethnicity can contribute to different treatment responses, as could the decision to take medication or undergo surgery in the first place.

“This emphasizes the need for additional, prospective randomized clinical trial research to explore why these differences exist,” Ali said. “While progress has been made, there is still much to learn about the optimal management of patients with metabolic and cardiovascular disorders.”

 

Considering a Multidisciplinary Approach to MASLD Treatment

Ghani and Ali also called for personalized treatment plans for metabolic-related disorders such as MASLD, as well as strong communication among specialists and with patients about the benefits and risks of choosing certain medications and procedures.

“Bariatric surgery is not a universal solution, and not all patients are suitable for surgery,” Ghani said. “We also can’t say at this point that drug treatments are worse than bariatric surgery. The effectiveness of these therapies can vary greatly depending on a patient’s health, lifestyle, and preferences.”

Looking ahead, MASLD studies should investigate long-term weight loss seen with bariatric surgery and different medications, said Katherine Schwenger, PhD, RD, a scientific associate at Toronto General Hospital in Toronto, Ontario, Canada.

“GLP-1s are a hot topic right now,” said Schwenger, who wasn’t involved with the study. But “we need to look at factors such as the longevity of weight loss. It’s hard to beat the success and sustainability of bariatric surgery.”

Ghani, Ali, and Schwenger reported no relevant disclosures.

CGM Use, GLP-1s, Drinking Water Key of 2025 ADA Standards

Article Type
Changed
Tue, 12/17/2024 - 06:52

The American Diabetes Association (ADA)’s Standards of Care — 2025 offer new guidance on broader use of continuous glucose monitoring (CGM), use of glucagon-like peptide 1 receptor agonists (GLP-1 RAs) beyond weight loss, management of metabolic dysfunction-associated liver disease (MAFLD), plus a strong endorsement for drinking water and much more. 

The Standards of Care — 2025 were published December 9 as a supplement to Diabetes Care. The standards “incorporate the latest information from clinical trial data and knowledge of diabetes management into a comprehensive guidelines document that will assist physicians in managing patients with diabetes in their practices,” said Mandeep Bajaj, MBBS, ADA’s President, Medicine & Science.

In an interview, Bajaj highlighted some of the most important of the clinical updates in 2024, including the following: 

  • Consideration of the use of continuous glucose monitoring devices in adults with type 2 diabetes (T2D) who don’t use insulin. Medicare and many other payers currently only cover CGM for people who use insulin or are otherwise at risk for hypoglycemia. However, some CGMs are now available over the counter, Bajaj pointed out.
  • Actions to be taken in the event of medication shortages. The ADA published guidance for this in the case of GLP-1 RAs on December 2. Essentially ADA advised substituting a different GLP-1 RA if possible. Nonapproved products aren’t recommended, but guidance is provided for people who choose to use them.
  • Use of GLP-1 RAs for heart and kidney health. Recommendations were revised to explicitly advise on choice of pharmacotherapy for individuals with T2D, based on new data on those with established or high risk for atherosclerotic cardiovascular disease, heart failure with preserved ejection fraction, and chronic kidney disease.
  • Treatment of MAFLD with moderate or advanced liver fibrosis. A new recommendation for use of a thyroid hormone receptor–beta agonist is based on trial data for resmetirom. Moreover, Bajaj noted, “we’ve adopted the new nomenclature, which was previously NAFLD and NASH, and now is MAFLD and MASH [metabolic-associated steatohepatitis].”
  • Advice to continue weight management therapy beyond achieving weight loss goals. This is based on a large amount of evidence that “stopping these therapies are associated with weight regain and increased cardiovascular risk,” Bajaj said, adding that this recommendation was made in collaboration with the Obesity Society.
  • Antibody-based screening for presymptomatic T1D in family members of people with T2D and others who may be at risk. “Individuals who test autoantibody positive should be provided with or referred for counseling about the risk of developing diabetes, diabetes symptoms, and [diabetic ketoacidosis] prevention and should be given consideration for referral to a specialized center for further evaluation and/or consideration of a clinical trial or approved therapy to potentially delay development of clinical diabetes,” the document says.
  • Screen for psychosocial issues. People with diabetes should be screened for concerns including diabetes distress, depression, anxiety, fear of hypoglycemia, and disordered eating behaviors. “People on insulin or sulfonylureas may have fear of hypoglycemia, but diabetes distress can happen to anyone with diabetes,” Bajaj pointed out. Caregivers and family members should be screened as well, the document advises.
  • Drink water, not soda. In the nutrition section, a new recommendation strongly advises drinking water instead of nutritive or nonnutritive sweetened beverages. “This is an important recommendation. So, when patients ask what’s the best thing to drink, our answer is drink water rather than Coca Cola or Diet Coke,” Bajaj said. But, what about people with diabetes who can’t quit their diet soda habit? “We’ve said that the nonnutritive sweetener is preferred over sugar sweetener, provided it’s in moderation and short term ... but the best is water.”

Bajaj has received grant support from ADA. He had no further disclosures.

Caregivers and family members should be screened as well, the document advises.
  • Drink water, not soda. In the nutrition section, a new recommendation strongly advises drinking water instead of nutritive or nonnutritive sweetened beverages. “This is an important recommendation. So, when patients ask what’s the best thing to drink, our answer is drink water rather than Coca Cola or Diet Coke,” Bajaj said. But, what about people with diabetes who can’t quit their diet soda habit? “We’ve said that the nonnutritive sweetener is preferred over sugar sweetener, provided it’s in moderation and short term ... but the best is water.”

Bajaj has received grant support from ADA. He had no further disclosures.

The American Diabetes Association (ADA)’s Standards of Care — 2025 offer new guidance on broader use of continuous glucose monitoring (CGM), use of glucagon-like peptide 1 receptor agonists (GLP-1 RAs) beyond weight loss, management of metabolic dysfunction-associated liver disease (MAFLD), plus a strong endorsement for drinking water and much more. 

The Standards of Care — 2025 were published December 9 as a supplement to Diabetes Care. The standards “incorporate the latest information from clinical trial data and knowledge of diabetes management into a comprehensive guidelines document that will assist physicians in managing patients with diabetes in their practices,” said Mandeep Bajaj, MBBS, ADA’s President, Medicine & Science.

In an interview, Bajaj highlighted some of the most important of the clinical updates in 2024, including the following: 

  • Consideration of the use of continuous glucose monitoring devices in adults with type 2 diabetes (T2D) who don’t use insulin. Medicare and many other payers currently only cover CGM for people who use insulin or are otherwise at risk for hypoglycemia. However, some CGMs are now available over the counter, Bajaj pointed out.
  • Actions to be taken in the event of medication shortages. The ADA published guidance for this in the case of GLP-1 RAs on December 2. Essentially ADA advised substituting a different GLP-1 RA if possible. Nonapproved products aren’t recommended, but guidance is provided for people who choose to use them.
  • Use of GLP-1 RAs for heart and kidney health. Recommendations were revised to explicitly advise on choice of pharmacotherapy for individuals with T2D, based on new data on those with established or high risk for atherosclerotic cardiovascular disease, heart failure with preserved ejection fraction, and chronic kidney disease.
  • Treatment of MAFLD with moderate or advanced liver fibrosis. A new recommendation for use of a thyroid hormone receptor–beta agonist is based on trial data for resmetirom. Moreover, Bajaj noted, “we’ve adopted the new nomenclature, which was previously NAFLD and NASH, and now is MAFLD and MASH [metabolic-associated steatohepatitis].”
  • Advice to continue weight management therapy beyond achieving weight loss goals. This is based on a large amount of evidence that “stopping these therapies are associated with weight regain and increased cardiovascular risk,” Bajaj said, adding that this recommendation was made in collaboration with the Obesity Society.
  • Antibody-based screening for presymptomatic T1D in family members of people with T2D and others who may be at risk. “Individuals who test autoantibody positive should be provided with or referred for counseling about the risk of developing diabetes, diabetes symptoms, and [diabetic ketoacidosis] prevention and should be given consideration for referral to a specialized center for further evaluation and/or consideration of a clinical trial or approved therapy to potentially delay development of clinical diabetes,” the document says.
  • Screen for psychosocial issues. People with diabetes should be screened for concerns including diabetes distress, depression, anxiety, fear of hypoglycemia, and disordered eating behaviors. “People on insulin or sulfonylureas may have fear of hypoglycemia, but diabetes distress can happen to anyone with diabetes,” Bajaj pointed out.

Noise and Artificial Light

Article Type
Changed
Tue, 12/10/2024 - 15:01

If you’ve ever taken a red-eye flight you have probably received a little packet of items the airline hopes will make your night flight more comfortable. If you had shelled out for “extra leg room” or “more comfort” seating, your little kit may have included some one-size-never-fits-all socks, a toothbrush large enough to brush one tooth at a time, and a miniature tube of toothpaste the GEICO gecko would laugh at. I have no personal knowledge what the folks in first class are getting, but I suspect it comes in a calf skin Gucci pouch. But, regardless of where you are sitting, at a minimum your night comfort kit will come with an eye mask and ear plugs. Unfortunately, these freebies are wasted on me because I already use a sleep mask every night and simply turn off my hearing aids to mute the noise. But I appreciate their effort.

Light and sound are well-known sleep disruptors. Temperature gets less attention, but is nonetheless a potent contributor to a poor night’s sleep in my experience. Just by chance while I was recovering from my most recent jet lag, I encountered two papers from investigators who were curious about the association between healthy sleep and ambient light and noise.

 

Dr. William G. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years.

The first paper looked at the relationship between artificial light at night (ALAN) and the incidence of insomnia. Looking at more than 300 Chinese cities, the investigators measured ALAN using satellite images and correlated the data with insomnia-related posts on social media. The researchers found when ALAN increased insomnia, related posts also increased. Not surprisingly, this relationship was greater in less populated cities during extreme temperatures and when air quality was poor. 

The second paper came from University of Texas at Houston. Using Fitbit data from more than 3000 adolescents, the researchers looked for correlations between blood pressure, sleep health, and “median nighttime anthropogenic noise levels by ZIP code.” Turns out the Federal Highway Administration has a readily available map of these noise levels. 

What the investigators found was that adequate sleep significantly reduces the risk of hypertension in adolescents. Not an unexpected finding to an ex-pediatrician like myself who is obsessed with the importance of sleep deprivation. However, the investigators and I were surprised that they had found no association between neighborhood noise alone or in combination with sleep health. I still suspect there is an association lurking there in the weeds of their data, but obviously it is not robust enough to float to the surface. It may be that in an acute situation noise can contribute to hypertension, but over time individuals adjust to the new sound level and their blood pressure settles down. Sleep is such a critical factor that it is not something our cardiovascular system can adapt to so easily. For various reasons most of us may already be functioning at the margins of sleep deprivation.

How then do we respond to observations by these two research teams? Do we take an approach similar to that the airlines have taken and prescribe, hand out, or sell ear plugs and sleep masks to every patient, or at least those with hypertension? This is what we could call the put-the-onus-on-the-patient approach, which seems to be the default when we lack the political will to take a bolder step.

The other path we could call the socio-environmental approach. The airlines have made a passing attempt at this by turning the cabin lights down on red-eye flights. I recently wrote about the “exposome,” which some investigators define as the total non-genetic exposures an individual endures during a lifetime and which in many situations has a negative effect on the individual’s health. These two papers clearly demonstrate that noise and nighttime artificial light are potent features of an uncountable number of individuals’ exposomes.

Noise and artificial light are both things that as a society we have the power to control if we could only muster up the political will to do so. Unfortunately, it is going to require something far beyond these two relatively obscure studies to move the needle in the direction of a healthier population. It’s is not a stretch to put obesity and the attention deficit phenomenon under this same umbrella where our society needs to look at itself for the answers.

 

Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

No, Diet and Exercise Are Not Better Than Drugs for Obesity

Article Type
Changed
Fri, 12/06/2024 - 13:46

They’re literally not better. Idealistically, sure, but literally not. And there’s really no debate. Meaning there’s never been a reproducible diet and exercise intervention that has led to anywhere near the average weight lost by those taking obesity medications. Furthermore, when it comes to the durability of weight lost, the gulf between outcomes with diet and exercise vs obesity medications is even more dramatic.

Looking to the literature, one of the most trotted out studies on lifestyle’s impact on weight over time is the Look AHEAD trial. Before useful obesity medications came on the scene, I trotted it out myself. Why? Because it was heartening when faced with the societal refrain that diet and exercise never worked to be able to show that yes, in fact they do. But how well?

Looking to Look AHEAD’s 4-year data (Obesity [Silver Spring]. 2011 Oct;19[10]:1987-1998), those randomized to the intensive lifestyle initiative arm averaged a 4.7% total body weight loss – an amount that remained the same at 8 years. But I chose 4 years because that’s a better comparison with the semaglutide SELECT trial that revealed at 4 years, the average sustained weight lost was more than double that of Look AHEAD’s, at 10.2%. Meanwhile the recently released SURMOUNT-4 study on tirzepatide reported that at 88 weeks, the average weight lost by participants was a near bariatric surgery level of 25.3% with no signs suggestive of pending regains.

Now maybe you want to cling to the notion that if you just try hard enough, your diet and exercise regime can beat our new meds. Well, it’s difficult to think of a more miserable, often actual vomit-inducing intervention, than the spectacle that used to air weekly on prime time called The Biggest Loser, where participants lived on a ranch and were berated and exercised all day long for the chance to lose the most and win a quarter of a million dollars. But even there, the meds prove to be superior. Although the short-term Biggest Loser data do look markedly better than meds (and than bariatric surgery), whereby the average participant lost 48.8% of their body weight during the grueling 7-month long, 24/7 competition, by postcompetition year 6, the average weight lost dropped to 12.7%.

Yet on November 26, when word came out that Medicare is likely to extend coverage to obesity medications for far more Americans, one of the most common refrains was something along the lines of yes, lifestyle modification is the best choice for dealing with obesity but it’s good that there will be medication options for those where that’s insufficient.

What?

The only reason that the world isn’t comfortable with the eminently provable truth that diet and exercise are inferior to obesity medications for weight management is weight bias. The message is that people simply aren’t trying hard enough. This despite our comfort in knowing that medications have more of an impact than lifestyle on pretty much every other chronic disease. Nor can I recall any other circumstance when coverage of a remarkably effective drug was qualified by the suggestion that known-to-be-inferior interventions are still the best or favored choice.

At this point, obesity medications are plainly the first-line choice of treatment. They provide not only dramatically greater and more durable weight loss than lifestyle interventions, they have also been shown to very significantly reduce the risk for an ever-growing list of other medical concerns including heart attacks, strokes, type 2 diabetes, hypertension, sleep apnea, fatty liver disease, and more, while carrying minimal risk.

Let it also be said that improvements to diet and exercise are worth striving for at any weight, though one should not lose sight of the fact that perpetual, dramatic, intentional, behavior change in the name of health requires vast amounts of wide-ranging privilege to enact — amounts far beyond the average person’s abilities or physiologies (as demonstrated with obesity by decades of disappointing long-term lifestyle outcome data). 

Let it also be said that some people will indeed find success solely through lifestyle and that not every person who meets the medical criteria for any medication’s prescription, including obesity medications, is required or encouraged to take it. The clinician’s job, however, at its most basic, is to inform patients who meet medical use criteria of their options, and if a medication is indicated, to inform them of that medication’s risks and benefits and expected outcomes, to help their patients come to their own treatment decisions.

It’s not a bad thing that we have medications that deliver better outcomes than lifestyle — in fact, it’s terrific, and thankfully that they do is true for pretty much every medical condition for which we have medication. That’s in fact why we have medications! And so this constant refrain of golly-gee wouldn’t it be better if we could just manage obesity with lifestyle changes needs to be put to rest — we literally know it wouldn’t be better, and it’s only weight bias that would lead this evidence-based statement to seem off-putting.

The clinician’s job, however, at its most basic, is to inform patients who meet medical use criteria of their options, and if a medication is indicated, to inform them of that medication’s risks and benefits and expected outcomes, to help their patients come to their own treatment decisions.

It’s not a bad thing that we have medications that deliver better outcomes than lifestyle — in fact, it’s terrific, and thankfully that they do is true for pretty much every medical condition for which we have medication. That’s in fact why we have medications! And so this constant refrain of golly-gee wouldn’t it be better if we could just manage obesity with lifestyle changes needs to be put to rest — we literally know it wouldn’t be better, and it’s only weight bias that would lead this evidence-based statement to seem off-putting.
