Medical schools with diversity, equity, and inclusion (DEI) initiatives could lose federal funding under a new bill proposed this week in the US House of Representatives. 

The Embracing Anti-Discrimination, Unbiased Curricula, and Advancing Truth in Education (EDUCATE) Act was introduced March 19 by North Carolina Rep. Greg Murphy (R-NC3). It aims to ban what the bill describes as “race-based mandates” at medical schools. 

The legislation highlights a larger national backlash, largely led by conservatives, against considering race and ethnicity in higher education after the Supreme Court overturned affirmative action last summer. 

According to the bill’s text, medical schools must not “establish, maintain, or contract with a [DEI] office, or any other functional equivalent.” They must also agree that they will not force students or faculty to acknowledge that “America is an oppressive nation” or that “individuals should be adversely treated on the basis of their sex, race, ethnicity, religion, color, or national origin.” 

If H.R. 7725 passes, noncompliant medical schools would no longer receive federal funding or be eligible to participate in guaranteed student loan programs. 

Advocating for colorblind medical school admissions overlooks the racism that still exists in society, said Vanessa Grubbs, MD, MPH, nephrologist and cofounder of the nonprofit Black Doc Village. She told this news organization that bills like H.R. 7725 distract from the real work of diversifying the physician workforce to achieve equitable care for all. 

“There’s a huge body of literature that shows when there is racial or cultural concordance, people have better satisfaction and health outcomes,” said Dr. Grubbs. “It’s really telling that the first thing the people dreaming up these bills say is that by having a diverse workforce, it automatically means that you have a less qualified workforce or that you’re lowering standards.”

The bill joins dozens of state legislative actions seeking to ban DEI principles in healthcare.

This week, Alabama legislators passed a bill prohibiting public universities from establishing DEI programs or using state money to sponsor events involving “divisive concepts.” If signed by the governor, the bill would go into effect on October 1, 2024, joining states like Tennessee and Utah with similar laws already on the books.

Industry groups are also grappling with anti-DEI sentiment. Earlier this month, the American Academy of Dermatology’s annual meeting took an unexpected turn when a member physician and 92 colleagues petitioned the academy to end its DEI programs, including scholarships and mentoring. A committee hearing the petition declined to send it to the Academy’s board.

Rep. Murphy, a urology surgeon who wrote a related editorial in the Wall Street Journal, argued that DEI ideology violates freedom of speech and allows medical schools to reject candidates for not being progressive enough. In the opinion piece, he and coauthor nephrologist Stanley Goldfarb, MD, referred to DEI efforts as “quackery” and a form of discrimination. 

Dr. Goldfarb is the chairman of Do No Harm, a Virginia-based advocacy group that has pushed to eradicate “identity politics” in medical education and clinical practice. The group was instrumental in suing the Louisiana governor for a law requiring that minority candidates fill some state medical board positions. It also filed a complaint against the Medical Board of California on behalf of two physicians, claiming the state’s mandated implicit bias training for healthcare professionals violates their First Amendment rights.

Following the Supreme Court’s ruling overturning affirmative action, the American Medical Association (AMA) adopted a policy advising medical schools to consider race as a factor in admissions alongside other criteria such as test scores, grades, and interviews. The policy provides a “necessary safeguard” to diversify the physician workforce and advance health equity, the AMA said at the time. 

The Association of American Medical Colleges supports DEI principles in medical education while advocating for race-neutral admissions practices like holistic review. This method considers the whole applicant, including their experiences, attributes, academic achievements, and the value they bring to the learning environment. 

H.R. 7725 has 35 cosponsors, many of whom are physicians. Podiatrist and Ohio Rep. Brad Wenstrup (R) said in a statement that medical education should be “free of discrimination” and that the bill would prevent physicians from “being forced to pledge, affirm, or adopt tenets that have infiltrated higher education.”

TOPLINE:

The risk for type 2 diabetes (T2D) was higher in individuals who followed a pro-inflammatory diet and had a high habitual salt intake than in those who followed an anti-inflammatory diet and used less salt.

METHODOLOGY:

• High scores on the dietary inflammatory index (DII) — a scoring system that measures the inflammatory potential of an individual’s diet — and high salt intake are associated with increased cardiovascular disease risk; however, studies investigating the association between DII and salt intake with incident T2D risk are scarce.
• Researchers investigated the association between a pro-inflammatory diet, habitual salt intake, and the risk for T2D among 171,094 participants from the UK Biobank (mean age, 55.98 years; 40.7% men).
• Participants were free of diabetes at baseline, had completed at least one dietary recall questionnaire, and were followed up for a median period of 13.5 years.
• The energy-adjusted DII was calculated on the basis of 28 food and nutrient parameter-specific scores, while habitual salt intake was assessed through self-reported frequency of adding salt to foods.
• Any newly diagnosed cases of T2D were considered the first occurrences of health outcomes.

TAKEAWAY:

• Incident cases of T2D were reported in 6216 individuals over the median follow-up period.
• The risk of developing T2D was 18% higher in individuals who followed a pro-inflammatory vs anti-inflammatory diet (adjusted hazard ratio [HR], 1.18; 95% CI, 1.11-1.25); the risk for T2D was elevated by 4% for each one-point increment in the energy-adjusted DII.
• Compared with participants who never or rarely added salt to foods, the risk for T2D increased gradually in those who sometimes (HR, 1.10; 95% CI, 1.04-1.16), usually (HR, 1.14; 95% CI, 1.05-1.24), and always (HR, 1.30; 95% CI, 1.15-1.47) added salt to foods.
• The risk for T2D was the highest in participants who followed a pro-inflammatory diet and always added salt to foods (HR, 1.60; 95% CI, 1.32-1.90) compared with those who followed an anti-inflammatory diet and never or rarely added salt to foods.

IN PRACTICE:

“Our findings indicate that a pro-inflammatory diet and higher habitual salt intake were associated with an increased risk of type 2 diabetes. These results support the public health promotion of an anti-inflammatory diet and reducing salt intake to prevent the onset of type 2 diabetes,” the authors wrote.

SOURCE:

This study was led by Wenqui Shen, MD, from the Department of Endocrinology and Metabolism, Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China, and published online in Diabetes, Obesity and Metabolism.

LIMITATIONS:

Data from a 24-hour dietary recall questionnaire were used to calculate the energy-adjusted DII, which might have led to incidences of incorrect reporting. This study could not measure all components of the DII score. Unmeasured variables and residual confounders might also be present, which were not considered in this analysis.

DISCLOSURES:

This study was supported by grants from the National Natural Science Foundation of China, Science and Technology Commission of Shanghai Municipality, Project of Biobank from the Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine, and other sources. The authors declared no conflicts of interest.

Informing patients of a dire diagnosis — or even one that will require significant lifestyle changes — is never easy. But what’s even more challenging is when patients don’t accept their medical condition or a future that might include a difficult treatment protocol or even new medications or surgery.

“This is a challenging space to be in because this isn’t an exact science,” said Jack Jacoub, MD, medical director of MemorialCare Cancer Institute at Orange Coast Memorial in Fountain Valley, California. “There’s no formal training to deal with this — experience is your best teacher.”

Ultimately, helping a person reconceptualize what their future looks like is at the heart of every one of these conversations, said Sourav Sengupta, MD, MPH, associate professor of psychiatry and pediatrics at the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo, Buffalo, New York. “As physicians, we’re charged with helping our patients navigate a difficult and challenging time in their life,” he told this news organization.

“It’s not infrequent that patients are struggling to rethink what it will be like to be a person with an illness that might be chronic and how this will change their life,” he said.

And because denial is commonly the initial way a patient might cope with absorbing news that’s hard to hear, you’ll need to be extremely patient and empathetic.

“The goal is to build trust with this person, including trust in you, the hospital itself, and the entire team treating the patient,” Dr. Jacoub said.

“A diagnosis, especially in my field of oncology, can be scary. Spending time explaining their prognosis is very important. This can’t be a rushed scenario.”

More advice on helping patients who are in denial about their medical condition:
 

Make Sure They Understand What’s Going on

In cardiology, it’s common for patients to be hospitalized when they first learn that they have a disease they must manage for the rest of their life, said Stephanie Saucier, MD, a noninvasive cardiologist and codirector of the Women’s Heart Wellness Program at Hartford Healthcare’s Heart and Vascular Institute.

“Especially after someone has had a heart attack, a stroke, or they had bypass or stents placed, I like to see what their understanding of the disease is,” Dr. Saucier said. “I ask them, ‘What do you understand about what happened to you’. It can get confusing when you’re in the hospital and are told a lot of information in a short period of time.”
 

Share the Data

If a patient remains resistant to the news of a diagnosis, sharing test results can be beneficial. “I’ll often say, ‘here are the scans; this is the path report; this is the bloodwork; this is your biopsy report; these are the things we have’,” Dr. Jacoub said.

“Yes, this is clinical, but it helps to communicate the information you have and do it with data. For example, I might add, ‘Would you like to see some of the things [results, scans, tests] we’re talking about today?’ This also helps establish trust.”
 

Help Them Wrap Their Mind Around a Lifelong Condition

It’s often challenging for patients to accept that what they think is a one-time health issue will affect them for a lifetime. “I use juvenile diabetes as a way to explain this,” Dr. Saucier said. “I ask them what they would do if, say, their child was diagnosed with juvenile diabetes.”

Of course, patients agree that they wouldn’t give a child insulin for only a brief period. They understand that the condition must be treated in the long term. This kind of analogy can help patients understand that they, too, have a disorder requiring lifelong treatment.
 

Be Ready to Respond

Dr. Sengupta says that it’s important to be prepared with an answer if your patient is challenging or suggests that the diagnosis is fake or that you don’t have their best interests in mind.

“It’s understandable that patients might feel frustrated and upset,” he said. “It’s challenging when somehow a patient doesn’t assume my best intent.”

They might say something like, “You’re trying to make more money” or “you’re a shill for a pharma company.” In that case, you must listen. Patiently explain, “I’m your doctor; I work for you; I’m most interested in you feeling healthy and well.”

Occasionally, you’ll need a thick skin when it comes to inaccurate, controversial, or conspiratorial conversations with patients.
 

Acknowledge Differences

News of an illness may clash with a person’s take on the world. “A cancer diagnosis, for example, may clash with religious beliefs or faith-based ideology about the healthcare system,” said Aaron Fletcher, MD, a board-certified otolaryngologist specializing in head and neck surgery at the Georgia Center for Ear, Nose, Throat, and Facial Plastic Surgery in Atlanta, Georgia.

“If you have a patient who is coming to you with these beliefs, you need to have a lot of empathy, patience, and good communication skills. It’s up to you to break through the initial doubt and do your best to explain things in layman’s terms.”
 

Find Mutual Ground

If your patient still denies their health issues, try to find one thing you can agree on regarding a long-term game plan. “I’ll say, ‘Can we at least agree to discuss this with other family members or people who care about you’?” Dr. Jacoub said.

“I always tell patients that loved ones are welcome to call me so long as they [the patient] give permission. Sometimes, this is all that it takes to get them to accept their health situation.”
 

Seven Ways to Cope With Diagnosis  Denial

This news organization asked David Cutler, MD, a board-certified family medicine physician at Providence Saint John›s Health Center in Santa Monica, California, for tips in helping patients who are having a challenging time accepting their condition:

• Listen Actively. Allow the patient to express their feelings and concerns without judgment. Active listening can help them feel heard and understood, which may open the door to discussing their condition more openly.
• Provide Information. Offer factual information about their medical condition, treatment options, and the potential consequences of denial. Provide resources such as pamphlets, websites, or books that they can review at their own pace.
• Encourage Professional Help. You may want to suggest that your patient seek professional help from a therapist, counselor, or support group. A mental health professional can assist patients in processing their emotions and addressing their denial constructively.
• Involve Trusted Individuals. Enlist the support of trusted friends, family members, or healthcare professionals who can help reinforce the importance of facing their medical condition.
• Respect Autonomy. While it’s essential to encourage the person to accept their diagnosis, ultimately, the decision to get treatment lies with them. Respect their autonomy and avoid pushing them too hard, which could lead to resistance or further denial.
• Be Patient and Persistent. Overcoming denial is often a gradual process. Be patient and persistent in supporting the person, even if progress seems slow.
• Set Boundaries. It’s essential to set boundaries to protect your well-being. While you can offer support and encouragement, you cannot force someone to accept their medical condition. Recognize when your efforts are not being productive and take care of yourself in the process.

Occasionally, you’ll need a thick skin when it comes to inaccurate, controversial, or conspiratorial conversations with patients.
 

Acknowledge Differences

News of an illness may clash with a person’s take on the world. “A cancer diagnosis, for example, may clash with religious beliefs or faith-based ideology about the healthcare system,” said Aaron Fletcher, MD, a board-certified otolaryngologist specializing in head and neck surgery at the Georgia Center for Ear, Nose, Throat, and Facial Plastic Surgery in Atlanta, Georgia.

“If you have a patient who is coming to you with these beliefs, you need to have a lot of empathy, patience, and good communication skills. It’s up to you to break through the initial doubt and do your best to explain things in layman’s terms.”
 

Find Mutual Ground

If your patient still denies their health issues, try to find one thing you can agree on regarding a long-term game plan. “I’ll say, ‘Can we at least agree to discuss this with other family members or people who care about you’?” Dr. Jacoub said.

“I always tell patients that loved ones are welcome to call me so long as they [the patient] give permission. Sometimes, this is all that it takes to get them to accept their health situation.”
 

Seven Ways to Cope With Diagnosis  Denial

This news organization asked David Cutler, MD, a board-certified family medicine physician at Providence Saint John›s Health Center in Santa Monica, California, for tips in helping patients who are having a challenging time accepting their condition:

• Listen Actively. Allow the patient to express their feelings and concerns without judgment. Active listening can help them feel heard and understood, which may open the door to discussing their condition more openly.
• Provide Information. Offer factual information about their medical condition, treatment options, and the potential consequences of denial. Provide resources such as pamphlets, websites, or books that they can review at their own pace.
• Encourage Professional Help. You may want to suggest that your patient seek professional help from a therapist, counselor, or support group. A mental health professional can assist patients in processing their emotions and addressing their denial constructively.
• Involve Trusted Individuals. Enlist the support of trusted friends, family members, or healthcare professionals who can help reinforce the importance of facing their medical condition.
• Respect Autonomy. While it’s essential to encourage the person to accept their diagnosis, ultimately, the decision to get treatment lies with them. Respect their autonomy and avoid pushing them too hard, which could lead to resistance or further denial.
• Be Patient and Persistent. Overcoming denial is often a gradual process. Be patient and persistent in supporting the person, even if progress seems slow.
• Set Boundaries. It’s essential to set boundaries to protect your well-being. While you can offer support and encouragement, you cannot force someone to accept their medical condition. Recognize when your efforts are not being productive and take care of yourself in the process.

Informing patients of a dire diagnosis — or even one that will require significant lifestyle changes — is never easy. But what’s even more challenging is when patients don’t accept their medical condition or a future that might include a difficult treatment protocol or even new medications or surgery.

“This is a challenging space to be in because this isn’t an exact science,” said Jack Jacoub, MD, medical director of MemorialCare Cancer Institute at Orange Coast Memorial in Fountain Valley, California. “There’s no formal training to deal with this — experience is your best teacher.”

Ultimately, helping a person reconceptualize what their future looks like is at the heart of every one of these conversations, said Sourav Sengupta, MD, MPH, associate professor of psychiatry and pediatrics at the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo, Buffalo, New York. “As physicians, we’re charged with helping our patients navigate a difficult and challenging time in their life,” he told this news organization.

“It’s not infrequent that patients are struggling to rethink what it will be like to be a person with an illness that might be chronic and how this will change their life,” he said.

And because denial is commonly the initial way a patient might cope with absorbing news that’s hard to hear, you’ll need to be extremely patient and empathetic.

“The goal is to build trust with this person, including trust in you, the hospital itself, and the entire team treating the patient,” Dr. Jacoub said.

“A diagnosis, especially in my field of oncology, can be scary. Spending time explaining their prognosis is very important. This can’t be a rushed scenario.”

More advice on helping patients who are in denial about their medical condition:
 

Make Sure They Understand What’s Going on

In cardiology, it’s common for patients to be hospitalized when they first learn that they have a disease they must manage for the rest of their life, said Stephanie Saucier, MD, a noninvasive cardiologist and codirector of the Women’s Heart Wellness Program at Hartford Healthcare’s Heart and Vascular Institute.

“Especially after someone has had a heart attack, a stroke, or they had bypass or stents placed, I like to see what their understanding of the disease is,” Dr. Saucier said. “I ask them, ‘What do you understand about what happened to you’. It can get confusing when you’re in the hospital and are told a lot of information in a short period of time.”
 

Share the Data

If a patient remains resistant to the news of a diagnosis, sharing test results can be beneficial. “I’ll often say, ‘here are the scans; this is the path report; this is the bloodwork; this is your biopsy report; these are the things we have’,” Dr. Jacoub said.

“Yes, this is clinical, but it helps to communicate the information you have and do it with data. For example, I might add, ‘Would you like to see some of the things [results, scans, tests] we’re talking about today?’ This also helps establish trust.”
 

Help Them Wrap Their Mind Around a Lifelong Condition

It’s often challenging for patients to accept that what they think is a one-time health issue will affect them for a lifetime. “I use juvenile diabetes as a way to explain this,” Dr. Saucier said. “I ask them what they would do if, say, their child was diagnosed with juvenile diabetes.”

Of course, patients agree that they wouldn’t give a child insulin for only a brief period. They understand that the condition must be treated in the long term. This kind of analogy can help patients understand that they, too, have a disorder requiring lifelong treatment.
 

Be Ready to Respond

Dr. Sengupta says that it’s important to be prepared with an answer if your patient is challenging or suggests that the diagnosis is fake or that you don’t have their best interests in mind.

“It’s understandable that patients might feel frustrated and upset,” he said. “It’s challenging when somehow a patient doesn’t assume my best intent.”

They might say something like, “You’re trying to make more money” or “you’re a shill for a pharma company.” In that case, you must listen. Patiently explain, “I’m your doctor; I work for you; I’m most interested in you feeling healthy and well.”

Occasionally, you’ll need a thick skin when it comes to inaccurate, controversial, or conspiratorial conversations with patients.

A recent study linking a niacin derivative to an increased risk for cardiovascular events has raised questions about the safety of this B vitamin, which is added to many food staples in the Western diet and taken in the form of supplements.

The findings, which were published in Nature Medicine, may also help explain why taking niacin, which lowers low-density lipoprotein cholesterol and raises high-density lipoprotein cholesterol, did not lead to a reduction in cardiovascular events in major clinical trials.

But could this essential micronutrient really have an adverse effect on cardiovascular risk, and what are the implications for niacin intake?

Senior author of the new study Stanley Hazen, MD, believes some prudence on excessive niacin intake may be justified.

“I’m not suggesting we should completely avoid niacin — it is an essential nutrient, but our results suggest that too much may be harmful,” Dr. Hazen said.

Niacin supplements are also sold with claims of antiaging effects, arthritis relief, and boosting brain function, although none of these claims have been proven. And the related compound, nicotinamide, is recommended to prevent skin cancer in high-risk patients; however, a recent study questioned that guidance.

“I would say to the general public that avoiding supplements containing niacin or related compounds could be a sensible approach at present, while these findings are investigated further.”

Other experts are unsure if such action is justified on the basis of this single study.
 

Residual Cardiovascular Risk

Dr. Hazen, who is chair of the Department of Cardiovascular & Metabolic Sciences, at the Lerner Research Institute, Cleveland Clinic, Cleveland, Ohio, explained to this news organization that they did not set out to study niacin.

“It began as a study to look for novel pathways involved in residual cardiovascular disease risk — the risk for cardiovascular events after adjusting for traditional risk factors such as cholesterol, blood pressure, and diabetes.”

The researchers began looking for compounds in plasma that predicted future adverse cardiovascular events in individuals undergoing elective diagnostic cardiac evaluation. Two of the leading candidates identified were niacin derivatives — 2PY and 4PY — that are only formed in the presence of excess niacin.

They then developed assays to measure 2PY and 4PY and conducted further studies in two validation cohorts — 2331 US individuals and a European cohort of 832 individuals. In both cohorts, elevated plasma levels of 2PY and 4PY predicted future adverse cardiovascular events, with a doubling in cardiovascular risk seen in those with levels in the highest vs the lowest quartile.

To move beyond these observational studies and to explore a potentially causal relationship, Dr. Hazen’s team went on to perform genome-wide association studies and found that genetic variants that tracked with higher levels of 4PY also linked to levels of the inflammatory marker, vascular cell adhesion molecule 1 (VCAM-1).

And in cell culture and animal studies, they found that 4PY was a driver of inflammation, upregulating VCAM-1 and eliciting vascular inflammation responses.

“So, we have shown in several different ways that the niacin derivative, 4PY, is linked to increased cardiovascular risk,” Dr. Hazen commented.
 

Significant Health Implications?

Dr. Hazen believed these findings could have significant health implications.

He noted that Western populations have been consuming large amounts of niacin ever since World War 2 when we began to fortify many foods with essential vitamins to avoid diseases caused by deficiencies. Niacin was added to foods to prevent pellagra — a disease characterized by inflamed skin, diarrhea, and dementia, that was often fatal.

“While we may have eliminated pellagra, have we, as a consequence, increased the prevalence of cardiovascular disease many years later?” Dr. Hazen asked.

This may be a clue to why niacin does not lower cardiovascular risk as much as would be expected from the degree of cholesterol lowering it brings about. “This is the niacin paradox and has led to the thought that there could be some kind of adverse effect that niacin is promoting. I think we may have found something that contributes to the niacin paradox,” he said.

However, the niacin pathway is complicated. Niacin is the major source of nicotinamide adenine dinucleotide (NAD), an integral molecule that allows cells to create energy. “Because it is so important, our bodies are designed to salvage and retain NADs, but once storage capacity is exceeded, then these 4PY and 2PY derivatives are generated,” Dr. Hazen explained. “But you have to really eat a lot of niacin-rich foods for this to happen.”

He is not claiming that niacin causes cardiovascular disease. “It is 4PY that appears to be the driver of vascular inflammation. And 4PY is a breakdown product of niacin. But there is more than one pathway that could lead to 4PY generation. There is a whole interconnecting network of compounds that interchange with each other — known as the niacin pool — any one or more of these compounds can be ingested and raise pool levels and ultimately 4PY levels. However, by far and away, niacin is one of the major sources,” Dr. Hazen commented.
 

Are High-Protein Diets Also Implicated?

Other sources of NADs include tryptophan, present in protein. And one of the genetic variants linked to changes in 4PY levels is connected to how dietary protein is directed into the niacin pool, raising the possibility that a high-protein diet may also raise cardiovascular risk in some people, Dr. Hazen noted.

Dr. Hazen estimated that about 3% of the niacin pool in a normal diet comes from protein intake, but that the percentage could increase substantially in very high–protein diets.

“Our data support the concept that if we lower our 4PY level long-term, then that would result in a reduction in cardiovascular disease. But this is still just a hypothesis. If we lower niacin intake, we will lower 4PY,” Dr. Hazen stated.

He said that this research is at too early a stage to give firm recommendations in what this means for the consumer.

“Based on these findings, I would advise people to avoid taking niacin or nicotinic acid or nicotinamide supplements and to eat a sensible balanced diet — maybe not to overdo the high protein–type diets. That’s all we can really say at the moment.”

Noting that niacin can also be one of the major components in energy drinks, he suggested it may be prudent to limit consumption of these products.
 

What Is the Optimum Niacin Intake?

Dr. Hazen noted that the recommended dietary allowance (RDA) for niacin is well known — between 14 and 18 mg, but he said the average American ingests four times that amount, and some people have substantially higher intakes — up to 50 times the RDA if taking supplements.

While food fortification with niacin may have been useful in the past, Dr. Hazen questioned whether it should still be mandated.

“In the US, you cannot buy flour or cereal or rice that is not fortified. And if you look closely, some products have much higher levels than those that are mandated. The food companies advertise this as a benefit, but there is no good data in support of that. What if several decades of eating excessive amounts of niacin has led to an increase in cardiovascular disease?”

He does not propose stopping all niacin fortification, “but maybe, we could have the choice of selecting an unfortified option,” he said.
 

Causal Link Not Proven

Commenting for this news organization, John Guyton, MD, Professor Emeritus of Medicine, Duke University Medical Center, Durham, North Carolina, who has been involved in niacin research for many years, said the Nature Medicine study showed “interesting and important results,” but they do not at this point prove a causal link between niacin intake and risk for cardiovascular disease.

“These findings need to be investigated further, and more studies are certainly justified, but I don’t think that this study alone makes an adequate case for restricting niacin intake, or thinking about stopping niacin fortification of foodstuffs,” Dr. Guyton said.

Noting that niacin is present in large quantities in many fast foods, he suggested the researchers may have just picked up the consequences of eating an unhealthy diet.

“If you look at foods that contain high quantities of niacin, red meat is at the top of the list. And if you think of a hamburger, niacin is present in relatively large quantities both the burger and the bun. So, these findings may just be a reflection of an overall unhealthy diet,” he commented.

Dr. Guyton also pointed out that major clinical trials with niacin have shown mixed results, and its effect on cardiovascular risk is still not completely understood. While the HPS2-THRIVE and AIM-HIGH trials did not show benefits in reducing cardiovascular events, an earlier study, the Coronary Drug Project in which the agent was given with food, did show some positive effects with substantial reductions in myocardial infarction and stroke, and there was the suggestion of a reduction in long-term mortality in the niacin group several years after the trial had ended.
 

Nicotinamide in Skin Cancer Prevention

What about the use of nicotinamide in skin cancer prevention?

Addressing this question, Kristin Bibee, MD, assistant professor of dermatology at Johns Hopkins University School of Medicine, Baltimore, pointed out that nicotinamide, although closely related to niacin, may have different effects. “This study does not specifically address nicotinamide supplementation and 4PY levels,” she said.

Diona Damian, MD, professor of dermatology at the University of Sydney, Camperdown, Australia, told this news organization that it was hard to extrapolate these findings on basal levels of niacin in a cardiac cohort to the administration of supra-physiological doses of nicotinamide for skin cancer prevention.

There may be different effects of supplemental niacin compared to nicotinamide, which lacks the vasodilatory effects seen with niacin, Dr. Damian said, adding that it would be interesting to see the results from higher, therapeutic nicotinamide doses in patients with and without cardiac disease.

She pointed out that high vs low levels of nicotinamide supplementation can have different and even opposite effects on cellular processes, such as upregulating or inhibiting DNA repair enzymes. At high doses, nicotinamide is anti-inflammatory in skin.

Dr. Damian noted that two phase 3 studies (ONTRAC and ONTRANS) of nicotinamide 500 mg twice daily for skin cancer prevention did not find a significant increase in cardiovascular events compared to placebo over 12 months.

“Oral nicotinamide has been shown to reduce nonmelanoma skin cancer by about a quarter in patients with normal immunity and multiple skin cancers. The doses used for skin cancer prevention are well above daily dietary levels, and treatment needs to be ongoing for the protective effects to continue. Nicotinamide should not be recommended as a preventive agent for people who have not had multiple skin cancers but should be reserved for those with a heavy burden of skin cancers,” she commented.

“For now, it would be reasonable to balance the benefits of skin cancer reduction against possible effects on inflammatory markers in patients with cardiac risk factors, when helping patients to decide whether or not nicotinamide therapy is appropriate for them,” she added.

Meanwhile, Dr. Hazen said the most exciting part of this new research is the discovery of a new pathway that contributes to cardiovascular disease and potentially a new target to treat residual cardiovascular risk.

“I believe our results show that we should be measuring 4PY levels and individuals with high levels need to be extra vigilant about lowering their cardiovascular risk.”

The next step will be to confirm these results in other populations and then to develop a diagnostic test to identify people with a high 4PY level, he said.

“So, we have shown in several different ways that the niacin derivative, 4PY, is linked to increased cardiovascular risk,” Dr. Hazen commented.
 

Significant Health Implications?

Dr. Hazen believed these findings could have significant health implications.

He noted that Western populations have been consuming large amounts of niacin ever since World War 2 when we began to fortify many foods with essential vitamins to avoid diseases caused by deficiencies. Niacin was added to foods to prevent pellagra — a disease characterized by inflamed skin, diarrhea, and dementia, that was often fatal.

“While we may have eliminated pellagra, have we, as a consequence, increased the prevalence of cardiovascular disease many years later?” Dr. Hazen asked.

This may be a clue to why niacin does not lower cardiovascular risk as much as would be expected from the degree of cholesterol lowering it brings about. “This is the niacin paradox and has led to the thought that there could be some kind of adverse effect that niacin is promoting. I think we may have found something that contributes to the niacin paradox,” he said.

However, the niacin pathway is complicated. Niacin is the major source of nicotinamide adenine dinucleotide (NAD), an integral molecule that allows cells to create energy. “Because it is so important, our bodies are designed to salvage and retain NADs, but once storage capacity is exceeded, then these 4PY and 2PY derivatives are generated,” Dr. Hazen explained. “But you have to really eat a lot of niacin-rich foods for this to happen.”

He is not claiming that niacin causes cardiovascular disease. “It is 4PY that appears to be the driver of vascular inflammation. And 4PY is a breakdown product of niacin. But there is more than one pathway that could lead to 4PY generation. There is a whole interconnecting network of compounds that interchange with each other — known as the niacin pool — any one or more of these compounds can be ingested and raise pool levels and ultimately 4PY levels. However, by far and away, niacin is one of the major sources,” Dr. Hazen commented.
 

Are High-Protein Diets Also Implicated?

Other sources of NADs include tryptophan, present in protein. And one of the genetic variants linked to changes in 4PY levels is connected to how dietary protein is directed into the niacin pool, raising the possibility that a high-protein diet may also raise cardiovascular risk in some people, Dr. Hazen noted.

Dr. Hazen estimated that about 3% of the niacin pool in a normal diet comes from protein intake, but that the percentage could increase substantially in very high–protein diets.

“Our data support the concept that if we lower our 4PY level long-term, then that would result in a reduction in cardiovascular disease. But this is still just a hypothesis. If we lower niacin intake, we will lower 4PY,” Dr. Hazen stated.

He said that this research is at too early a stage to give firm recommendations in what this means for the consumer.

“Based on these findings, I would advise people to avoid taking niacin or nicotinic acid or nicotinamide supplements and to eat a sensible balanced diet — maybe not to overdo the high protein–type diets. That’s all we can really say at the moment.”

Noting that niacin can also be one of the major components in energy drinks, he suggested it may be prudent to limit consumption of these products.
 

What Is the Optimum Niacin Intake?

Dr. Hazen noted that the recommended dietary allowance (RDA) for niacin is well known — between 14 and 18 mg, but he said the average American ingests four times that amount, and some people have substantially higher intakes — up to 50 times the RDA if taking supplements.

While food fortification with niacin may have been useful in the past, Dr. Hazen questioned whether it should still be mandated.

“In the US, you cannot buy flour or cereal or rice that is not fortified. And if you look closely, some products have much higher levels than those that are mandated. The food companies advertise this as a benefit, but there is no good data in support of that. What if several decades of eating excessive amounts of niacin has led to an increase in cardiovascular disease?”

He does not propose stopping all niacin fortification, “but maybe, we could have the choice of selecting an unfortified option,” he said.
 

Causal Link Not Proven

Commenting for this news organization, John Guyton, MD, Professor Emeritus of Medicine, Duke University Medical Center, Durham, North Carolina, who has been involved in niacin research for many years, said the Nature Medicine study showed “interesting and important results,” but they do not at this point prove a causal link between niacin intake and risk for cardiovascular disease.

“These findings need to be investigated further, and more studies are certainly justified, but I don’t think that this study alone makes an adequate case for restricting niacin intake, or thinking about stopping niacin fortification of foodstuffs,” Dr. Guyton said.

Noting that niacin is present in large quantities in many fast foods, he suggested the researchers may have just picked up the consequences of eating an unhealthy diet.

“If you look at foods that contain high quantities of niacin, red meat is at the top of the list. And if you think of a hamburger, niacin is present in relatively large quantities both the burger and the bun. So, these findings may just be a reflection of an overall unhealthy diet,” he commented.

Dr. Guyton also pointed out that major clinical trials with niacin have shown mixed results, and its effect on cardiovascular risk is still not completely understood. While the HPS2-THRIVE and AIM-HIGH trials did not show benefits in reducing cardiovascular events, an earlier study, the Coronary Drug Project in which the agent was given with food, did show some positive effects with substantial reductions in myocardial infarction and stroke, and there was the suggestion of a reduction in long-term mortality in the niacin group several years after the trial had ended.
 

Nicotinamide in Skin Cancer Prevention

What about the use of nicotinamide in skin cancer prevention?

Addressing this question, Kristin Bibee, MD, assistant professor of dermatology at Johns Hopkins University School of Medicine, Baltimore, pointed out that nicotinamide, although closely related to niacin, may have different effects. “This study does not specifically address nicotinamide supplementation and 4PY levels,” she said.

Diona Damian, MD, professor of dermatology at the University of Sydney, Camperdown, Australia, told this news organization that it was hard to extrapolate these findings on basal levels of niacin in a cardiac cohort to the administration of supra-physiological doses of nicotinamide for skin cancer prevention.

There may be different effects of supplemental niacin compared to nicotinamide, which lacks the vasodilatory effects seen with niacin, Dr. Damian said, adding that it would be interesting to see the results from higher, therapeutic nicotinamide doses in patients with and without cardiac disease.

She pointed out that high vs low levels of nicotinamide supplementation can have different and even opposite effects on cellular processes, such as upregulating or inhibiting DNA repair enzymes. At high doses, nicotinamide is anti-inflammatory in skin.

Dr. Damian noted that two phase 3 studies (ONTRAC and ONTRANS) of nicotinamide 500 mg twice daily for skin cancer prevention did not find a significant increase in cardiovascular events compared to placebo over 12 months.

“Oral nicotinamide has been shown to reduce nonmelanoma skin cancer by about a quarter in patients with normal immunity and multiple skin cancers. The doses used for skin cancer prevention are well above daily dietary levels, and treatment needs to be ongoing for the protective effects to continue. Nicotinamide should not be recommended as a preventive agent for people who have not had multiple skin cancers but should be reserved for those with a heavy burden of skin cancers,” she commented.

“For now, it would be reasonable to balance the benefits of skin cancer reduction against possible effects on inflammatory markers in patients with cardiac risk factors, when helping patients to decide whether or not nicotinamide therapy is appropriate for them,” she added.

Meanwhile, Dr. Hazen said the most exciting part of this new research is the discovery of a new pathway that contributes to cardiovascular disease and potentially a new target to treat residual cardiovascular risk.

“I believe our results show that we should be measuring 4PY levels and individuals with high levels need to be extra vigilant about lowering their cardiovascular risk.”

The next step will be to confirm these results in other populations and then to develop a diagnostic test to identify people with a high 4PY level, he said.

A new study raises a cautionary note on time-restricted eating (TRE), a type of intermittent fasting that is gaining popularity.

The observational analysis of over 20,000 US adults showed that those who limited their eating to a period of less than 8 hours per day had a higher risk for cardiovascular mortality compared with peers who ate across the typical 12-16 hours per day. This was the case in the overall sample and in those with cardiovascular disease (CVD) or cancer.

Lead author Victor Wenze Zhong, PhD, cautioned that the findings “require replication and we cannot demonstrate 8-hour TRE causes cardiovascular death in this observational study.

“However, it’s important for patients, particularly those with existing heart conditions or cancer, to be aware of the positive association between an 8-hour eating window and cardiovascular death,” Dr. Zhong, professor and chair, Department of Epidemiology and Biostatistics, School of Public Health, Shanghai Jiao Tong University School of Medicine, Shanghai, China, told this news organization. 

The results (Abstract P192) were presented March 18 at the American Heart Association (AHA) Epidemiology and Prevention/Lifestyle and Cardiometabolic Health Scientific Sessions 2024.
 

‘Provocative’ Results 

Short-term randomized controlled trials have suggested that 8-hour TRE may improve cardiometabolic risk profiles, but the potential long-term effects of this eating pattern are unknown. 

The observation that TRE may have short-term benefits but long-term adverse effects is “interesting and provocative” and needs further study, Christopher D. Gardner, PhD, professor of medicine at Stanford University in California, who wasn’t involved in the study, said in a conference statement, and he agreed that much more research is needed. 

The researchers analyzed data on dietary patterns for 20,078 adults (mean age, 48 years; 50% men; 73% non-Hispanic White) who participated in the 2003-2018 National Health and Nutrition Examination Surveys (NHANES). All of them completed two 24-hour dietary recall questionnaires within the first year of enrollment. Deaths through the end of 2019 were determined via the National Death Index.

During a median follow-up of 8 years, there were 2797 deaths due to any cause, including 840 CV deaths and 643 cancer deaths. 

In the overall sample, compared with an eating duration of 12-16 hours, 8-hour TRE was significantly associated with an increased risk for CV mortality (hazard ratio [HR], 1.91; 95% CI, 1.20-3.03).

This association was also observed in adults with CVD (HR, 2.07; 95% CI, 1.14-3.78) and adults with cancer (HR, 3.04; 95% CI, 1.44-6.41). 

Other eating durations were not associated with CV mortality, except for eating duration of 8 to less than 10 hours in people with CVD (HR, 1.66; 95% CI, 1.03-2.67). 

No significant associations were found between eating duration and all-cause or cancer mortality in the overall sample and CVD/cancer subsamples, except that eating duration of more than 16 hours was associated with a lower risk for cancer mortality in people with cancer (HR, 0.47; 95% CI, 0.23-0.95).
 

Quality More Important Than Timing 

Dr. Zhong noted that the study doesn’t address the underlying mechanisms driving the observed association between 8-hour TRE and CV death. 

“However, we did observe that people who restricted eating to a period less than 8 hours per day had less lean muscle mass compared with those with typical eating duration of 12-16 hours. Loss of lean body mass has been linked to higher risk of cardiovascular mortality,” Dr. Zhong said. 

“Based on the evidence as of now, focusing on what people eat appears to be more important than focusing on the time when they eat. There are certain dietary approaches with compelling health benefits to choose, such as DASH diet and Mediterranean diet,” Dr. Zhong said.

Intermittent fasting is “certainly an interesting concept and one on which the potential mechanisms underlying the improvements in short outcome studies and preclinical studies in animals are strongly being pursued,” Sean P. Heffron, MD, cardiologist at the Center for the Prevention of Cardiovascular Disease at NYU Langone Heart, New York, who wasn’t involved in the study, told this news organization. 

Dr. Heffron expressed skepticism about the study results calling them “far from complete” and noted that data on diet was based on only 2-day diet records without correction for confounding variables. 

Dr. Heffron also noted that the restricted diet group has more smokers and more men. “I would “strongly anticipate that once appropriate corrections are made, the findings will no longer persist in statistical significance,” Dr. Heffron said.

He emphasized the need for more rigorous research before making clinical recommendations. When patients ask about intermittent fasting, Dr. Heffron said he tells them, “If it works for you, that’s fine,” but he doesn’t provide a recommendation for or against it. 

Funding for the study was provided by the National Key Research and Development Program of China and the National Science Foundation of China. Zhong, Dr. Heffron and Dr. Gardner have no relevant disclosures.

The following scenario was discussed during a forum at a meeting recently:

Two employees managing the front desk are clock watchers, always the first to leave at 11:59 a.m. for lunch and at 4:59 p.m. for the end of the day no matter what is happening. This leaves the other employees stuck with their work.

I have seen clock watching often enough to know that it is widely practiced, and widely reviled by coworkers and managers alike. Generally, clock watchers — sometimes referred to in modern parlance as “quiet quitters” — radiate a palpable sense of “I don’t want to be here.”

Physicians typically can’t identify with clock watching behavior, because we learned early on that patient-care tasks must be pursued to completion; if that involves working past the usual “quitting time,” so be it. So your first task in dealing with this problem is to determine its cause. The clock watcher label may be unfair. There may be legitimate reasons for certain employees to leave work at precisely 4:59 every day. Perhaps they must pick up children, or they have a second job to get to. The label usually comes from a pattern of consistent, repeated behavior. And if more than one employee is exhibiting the same behavior in the same office, the likelihood of a valid explanation decreases proportionally.

A common cause of clock watching is a lack of employees’ commitment to their jobs. They don’t see the point in putting in extra effort, so they run out the door as soon as possible. There are many reasons why this might be the case. For example, the workload in your office may be too large to be accomplished in the time available by the number of people you employ. The solution might be to simply hire additional personnel.

Another common cause is a lack of communication between physicians, managers, and lower-level employees. If staffers are raising concerns or potential solutions, and management is not listening to their opinions or ideas, they will stop offering them. Alternatively, other staff members may not be pulling their weight. When there is a large imbalance in the contribution of team members, the higher performers will stop trying.

Over my 40 plus years in practice, I have had my share of clock watchers. I try the best I can not to let employees’ time commitment practices impact my valuation of their work. I always attempt to focus on quality and productivity. It isn’t easy, but I always try to address the issues behind clock watching behavior. As such, I can’t recall ever having to fire anyone for clock watching. Here are some of the strategies that have worked for me over the years:

1. Set clear expectations. Clearly communicate job responsibilities and expectations regarding time management and patient care. Ensure that all staff understand the importance of dedicating the necessary time to each patient, regardless of the time of day.

2. Foster a patient-centered culture. Cultivate a work environment that prioritizes patient care above all. This can help shift the focus from watching the clock to ensuring high-quality patient care.

3. Provide adequate breaks. Ensure that staff schedules include sufficient breaks. Overworked staff are more likely to watch the clock. Adequate rest periods can help alleviate this issue.

4. Offer flexibility where possible. If feasible, offer some degree of scheduling flexibility. This can help staff manage their personal time more effectively, potentially reducing the tendency to watch the clock.

5. Implement time management training. Offer training sessions focused on time management and efficiency. This can help staff manage their duties more effectively, reducing the need to constantly check the time.

6. Encourage open communication. Create an environment where staff feel comfortable discussing their concerns, including issues related to workload and time management. This can help identify and address specific factors contributing to clock watching.

7. Monitor and provide feedback. Regularly monitor staff performance and provide constructive feedback. If clock watching is observed, discuss it directly with the employee, focusing on the impact on patient care and the work environment.

8. Recognize and reward. Acknowledge and reward staff who consistently provide high-quality care and demonstrate effective time management. Recognition can motivate others to adjust their behavior.

9. Evaluate workloads. Regularly assess staff workloads to ensure they are manageable. Overburdened employees are more likely to engage in clock watching.

10. Lead by example. Management should model the behavior they wish to see in their staff. Demonstrating a commitment to patient care and effective time management can set a positive example.

A common cause of clock watching is a lack of employees’ commitment to their jobs. They don’t see the point in putting in extra effort, so they run out the door as soon as possible. There are many reasons why this might be the case. For example, the workload in your office may be too large to be accomplished in the time available by the number of people you employ. The solution might be to simply hire additional personnel.

Another common cause is a lack of communication between physicians, managers, and lower-level employees. If staffers are raising concerns or potential solutions, and management is not listening to their opinions or ideas, they will stop offering them. Alternatively, other staff members may not be pulling their weight. When there is a large imbalance in the contribution of team members, the higher performers will stop trying.

Over my 40 plus years in practice, I have had my share of clock watchers. I try the best I can not to let employees’ time commitment practices impact my valuation of their work. I always attempt to focus on quality and productivity. It isn’t easy, but I always try to address the issues behind clock watching behavior. As such, I can’t recall ever having to fire anyone for clock watching. Here are some of the strategies that have worked for me over the years:

1. Set clear expectations. Clearly communicate job responsibilities and expectations regarding time management and patient care. Ensure that all staff understand the importance of dedicating the necessary time to each patient, regardless of the time of day.

2. Foster a patient-centered culture. Cultivate a work environment that prioritizes patient care above all. This can help shift the focus from watching the clock to ensuring high-quality patient care.

3. Provide adequate breaks. Ensure that staff schedules include sufficient breaks. Overworked staff are more likely to watch the clock. Adequate rest periods can help alleviate this issue.

4. Offer flexibility where possible. If feasible, offer some degree of scheduling flexibility. This can help staff manage their personal time more effectively, potentially reducing the tendency to watch the clock.

5. Implement time management training. Offer training sessions focused on time management and efficiency. This can help staff manage their duties more effectively, reducing the need to constantly check the time.

6. Encourage open communication. Create an environment where staff feel comfortable discussing their concerns, including issues related to workload and time management. This can help identify and address specific factors contributing to clock watching.

7. Monitor and provide feedback. Regularly monitor staff performance and provide constructive feedback. If clock watching is observed, discuss it directly with the employee, focusing on the impact on patient care and the work environment.

8. Recognize and reward. Acknowledge and reward staff who consistently provide high-quality care and demonstrate effective time management. Recognition can motivate others to adjust their behavior.

9. Evaluate workloads. Regularly assess staff workloads to ensure they are manageable. Overburdened employees are more likely to engage in clock watching.

10. Lead by example. Management should model the behavior they wish to see in their staff. Demonstrating a commitment to patient care and effective time management can set a positive example.

Unwanted weight gain is a common problem for women after menopause. Primary care clinicians have likely heard from patients that attempts at shedding extra pounds are not working.

Nearly three fourths of women aged 60 years and older in the United States are overweight. Some may blame menopause for this trend. But the life stage itself does not cause weight gain. Aging does: Women gain about 1.5 pounds per year on average starting almost a decade prior to menopause to a decade after their final menstrual cycle, according to research.

“A lot of women are in tears because they have gained 10 or 15 pounds,” said Stephanie Faubion, MD, medical director of The Menopause Society and director of the Mayo Clinic Center for Women’s Health in Jacksonville, Florida.

A shortage of obesity and menopause specialists means primary care clinicians must understand the intersection of weight management and how the body functions after menopause.

“The importance of weight management in midlife cannot be overemphasized,” Dr. Faubion said. “Excess weight around the middle increases the risk of diabetes and heart disease and that is directly related to the loss of estrogen.”

The loss of estrogen due to menopause also causes the redistribution of fat from the thighs, hips, and buttocks to the midsection, which can be more difficult to trim. And women naturally lose muscle mass as they age, in part because the hormone is important to muscle functioning, according to Maria Daniela Hurtado Andrade, MD, PhD, assistant professor of medicine at Mayo Clinic Alix School of Medicine in Jacksonville, Florida.

“Menopause compounds the changes associated with aging: It makes them worse,” Dr. Hurtado Andrade said.

Mounting evidence has linked obesity-related systemic inflammation with an increased risk for cardiovascular disease, including heart attacks and vascular damage.

Michael Knight, MD, clinical associate professor of medicine and a weight loss specialist at the George Washington University in Washington, DC, estimated that more than half of his patients are postmenopausal women.

He recommended clinicians look for adipose tissue dysfunction, which can cause localized insulin resistance and affect metabolic health. Research suggests clinicians can perform a basic metabolic panel, in addition to testing for triglyceride, low-density lipoprotein, and renal function levels. Several other recent studies have pointed to using waist circumference, insulin resistance, or presence of metabolic syndrome to diagnose adipose tissue dysfunction.

Beyond Diet and Exercise

Physicians should ask their patients about physical activity, the type of foods they are eating, and changes in day-to-day movement, Dr. Knight advised.

Pharmacotherapy or surgical options should be considered for some patients, according to Karen Adams, MD, clinical professor of obstetrics and gynecology and a lifestyle medicine specialist at Stanford Medicine in Palo Alto, California. Postmenopausal women who want to lose more than 5%-10% of their body weight likely will need another modality in addition to diet and exercise.

“What’s important is transitioning the patient from feeling like they’ve failed to a mindset of seeking help or seeking care for this condition,” she said. Dr. Adams, a certified menopause specialist, uses the idea of “good enough” with her patients and suggests they think of weight loss as a journey, which may require different tools at various points.

Glucagon-like peptide 1 receptor agonists like semaglutide or tirzepatide are some of the most effective drugs for obesity, according to Dr. Knight.

In addition to these drugs, hormone replacement therapy in combination with the weight loss drug semaglutide may improve weight loss and reduce cardiometabolic risk in postmenopausal women compared with semaglutide alone, as reported in a study Dr. Hurtado Andrade and Dr. Faubion recently coauthored. Improving vasomotor symptoms improved sleep, physical activity, and quality of life, which all can affect efforts to lose weight.

Most patients who struggle to lose weight using diet and exercise methods alone usually do not maintain a healthy weight long term, according to Knight. Physicians need a comprehensive strategy to introduce options like medications or surgery when indicated for long-term, weight management solutions.

Tips for primary care clinicians in helping postmenopausal women lose weight:

• Develop an effective solution that works for your patient’s lifestyle. If you don’t have one, make a referral to a weight loss specialist.
• Educate patients about obesity and postmenopausal weight loss challenges, to help destigmatize the condition. Explain that obesity is a chronic disease, like hypertension or diabetes.
• Exercise suggestions should consider issues like walkable neighborhoods, access and affordability of gym membership, and home broadband access.
• Strength training should be recommended to counter loss of muscle mass that comes with aging.
• Consider a patient’s culture when discussing healthier alternatives to their usual diet.
• Suggest simple changes to start, like eliminating simple carbohydrates — white bread, pasta, and white rice — as a good place to start.

Body mass index was not designed to be a clinical tool and does not fully assess weight in many populations. Risk for chronic diseases and obesity varies depending on whether a person carries weight centrally or on the hips and thighs.

But well before menopause, clinicians can educate their female patients on what body changes to expect and be more mindful about which medications to not prescribe.

People in menopause or perimenopause are frequently prescribed weight-promoting drugs like antidepressants for mood swings or gabapentin for hot flashes. Clinicians should conduct a medication review and look for alternatives to drugs that are associated with weight gain.

The best approach is to try to avoid weight gain in the first place, which can be easier than trying to lose later, Dr. Faubion said. “You can’t just exercise your way out of it,” she said.

Dr. Adams, Dr. Faubion, and Dr. Hurtado Andrade reported no disclosures. Dr. Knight is a former consultant with Novo Nordisk.

TOPLINE:

Methylphenidate was associated with a small increased risk for cardiovascular events in individuals taking the drug for more than 6 months in a new cohort study.

METHODOLOGY:

• The retrospective, population-based cohort study was based on national Swedish registry data and included 26,710 patients with attention-deficit/hyperactivity disorder (ADHD) aged 12-60 years (median age 20) who had been prescribed methylphenidate between 2007 and 2012. They were each matched on birth date, sex, and county with up to 10 nonusers without ADHD (a total of 225,672 controls).
• Rates of cardiovascular events, including ischemic heart disease, venous thromboembolism, heart failure, or tachyarrhythmias 1 year before methylphenidate treatment and 6 months after treatment initiation were compared between individuals receiving methylphenidate and matched controls using a Bayesian within-individual design.

TAKEAWAY:

• The overall incidence of cardiovascular events was 1.51 per 10,000 person-weeks for individuals receiving methylphenidate and 0.77 for the matched controls.
• Individuals treated with methylphenidate had an 87% posterior probability of having a higher rate of cardiovascular events after treatment initiation (incidence rate ratio [IRR], 1.41) than matched controls (IRR, 1.18).
• Individuals taking methylphenidate had a 70% posterior probability for a greater than 10% increased risk for cardiovascular events than controls and a 49% posterior probability for an increased risk larger than 20%.
• No difference was found in this risk between individuals with and without a history of cardiovascular disease.

IN PRACTICE:

The researchers concluded that these results support a small (10%) increased risk for cardiovascular events in individuals receiving methylphenidate compared with matched controls after 6 months of treatment. The probability of finding a difference in risk between users and nonusers decreased when considering risk for 20% or larger, with no evidence of differences between those with and without a history of cardiovascular disease. They said the findings suggest the decision to initiate methylphenidate should incorporate considerations of potential adverse cardiovascular effects among the broader benefits and risks for treatment for individual patients.

SOURCE:

The study, led by Miguel Garcia-Argibay, PhD, Örebro University, Örebro, Sweden, was published online in JAMA Network Open on March 6.

LIMITATIONS:

The data were observational, and thus, causality could not be inferred. Lack of information on methylphenidate dose meant that it was not possible to assess a dose effect. Compliance with the medication was also not known, and the association may therefore have been underestimated. The findings of this study were based on data collected from a Swedish population, which may not be representative of other populations.

DISCLOSURES:

The study received funding from the European Union’s Horizon 2020 research and innovation program and the Swedish Research Council for Health, Working Life, and Welfare.

TOPLINE:

Depression is linked to a significantly increased risk for cardiovascular disease (CVD), particularly in women, new data from a large retrospective cohort study show. Researchers suggest that screening and treating patients for depression may lead to a decreased incidence of CVD.

METHODOLOGY:

• Researchers analyzed health insurance claims from more than 4 million Japanese patients filed between 2005 and 2022.
• Participants were 18-75 (median age, 44) without a history of CVD or stroke, heart failure, or atrial fibrillation.
• Investigators followed participants for a mean period of 2.5-3.5 years to observe the number of CVD events in those who had a diagnosis of depression.
• During the follow-up period, there were 119,000 CVD events in men (14 per 10,000 person-years) and 61,800 CVD events in women (111 per 10,000 person-years).

TAKEAWAY:

• Compared with women without depression, those with depression had a 64% higher risk for CVD (hazard ratio [HR], 1.64), while men with depression had a 39% higher risk for CVD vs their counterparts without depression (HR, 1.39; P < .001).
• This association was significant even after controlling for various factors such as body mass index, diabetes, smoking, alcohol consumption, and physical inactivity.
• Investigators offered several theories about the increased risk for CVD in women with depression, including how depression during hormonal shifts can contribute to a greater impact on cardiovascular health.

IN PRACTICE:

“Healthcare professionals must recognize the important role of depression in the development of CVD and emphasize the importance of a comprehensive, patient-centered approach to its prevention and management,” study author Hidehiro Kaneko, MD, said in a press release. “Assessing the risk of CVD in depressed patients and treating and preventing depression may lead to a decrease of CVD cases.”

SOURCE:

Keitaro Senoo, MD, of the Kyoto Prefectural University of Medicine, Kyoto, Japan, led the study, which was published online on March 12 in JACC: Asia.

LIMITATIONS:

The study is observational, so causality between depression and subsequent CVD events cannot be established. In addition, depression severity is unknown.

DISCLOSURES:

The study was funded by the Ministry of Health, Labour, and Welfare, Japan, and the Ministry of Education, Culture, Sports, Science, and Technology, Japan. There were no disclosures reported.

• This association was significant even after controlling for various factors such as body mass index, diabetes, smoking, alcohol consumption, and physical inactivity.
• Investigators offered several theories about the increased risk for CVD in women with depression, including how depression during hormonal shifts can contribute to a greater impact on cardiovascular health.

IN PRACTICE:

“Healthcare professionals must recognize the important role of depression in the development of CVD and emphasize the importance of a comprehensive, patient-centered approach to its prevention and management,” study author Hidehiro Kaneko, MD, said in a press release. “Assessing the risk of CVD in depressed patients and treating and preventing depression may lead to a decrease of CVD cases.”

SOURCE:

Keitaro Senoo, MD, of the Kyoto Prefectural University of Medicine, Kyoto, Japan, led the study, which was published online on March 12 in JACC: Asia.

LIMITATIONS:

The study is observational, so causality between depression and subsequent CVD events cannot be established. In addition, depression severity is unknown.

DISCLOSURES:

The study was funded by the Ministry of Health, Labour, and Welfare, Japan, and the Ministry of Education, Culture, Sports, Science, and Technology, Japan. There were no disclosures reported.

Silence Therapeutics shared positive topline 36-week data from its ongoing phase 2 study of zerlasiran, a long-acting agent directed at lowering Lp(a) levels. 

In a statement, the company said the study shows a highly significant reduction from baseline in Lp(a) levels with zerlasiran compared with placebo at 36 weeks, the primary endpoint.

Zerlasiran (formerly known as SLN360), is a short interfering RNA (siRNA) agent, or “ gene silencing” therapy. It binds to and temporarily blocks the action of the LPA gene which encodes for apolipoprotein(a), a dominant and a rate-limiting component in the hepatic synthesis of the Lp(a) particle.

A previous phase 1 study showed that single subcutaneous doses of the drug, ranging from 30 mg to 600 mg, produced a dose-dependent reduction in Lp(a) plasma levels at 45-60 days.

The current double-blind placebo-controlled phase 2 trial — known as ALPACAR-360 — enrolled 178 patients at high risk for atherosclerotic cardiovascular events who had elevated levels of Lp(a), ie, ≥ 125 nmol/L (median baseline Lp(a) was approximately 215 nmol/L). They were randomized to zerlasiran or placebo. 

Zerlasiran was administered at 300 mg subcutaneously every 16 or 24 weeks or at 450 mg every 24 weeks. 

Results reported by the company show a median percentage reduction in Lp(a) of ≥ 90% for both doses at week 36, with no new safety concerns identified during this treatment period.

The 60-week study is ongoing, and secondary endpoints, including change in Lp(a) from baseline to 48 weeks (end of treatment period) and 60 weeks (end of study) and potential effects on other lipids/lipoproteins, will be evaluated.

Silence says it plans to report topline 48-week data from the ALPACAR-360 study in the second quarter of this year.

Elevated levels of Lp(a) represent a genetic risk factor for cardiovascular disease, which is believed to affect approximately 20% of the population. Although there are currently no approved Lp(a)-lowering therapies, several drug candidates are in late-stage clinical testing.
