On August 13, 2024, the Food and Drug Administration (FDA) approved nemolizumab for the treatment of adults with prurigo nodularis (PN).

A first-in-class monoclonal antibody specifically designed to inhibit interleukin (IL)–31 signaling, nemolizumab, will be available in a prefilled pen for subcutaneous injection and will be marketed as Nemluvio. It is currently under FDA review for treating atopic dermatitis in adolescents and adults. 

Approval for PN is based on data from the phase 3 OLYMPIA clinical trial program, which evaluated the efficacy and safety of nemolizumab administered subcutaneously every 4 weeks in 560 patients with PN, according to a press release from Galderma, the manufacturer.

According to the press release, in OLYMPIA 1 and OLYMPIA 2, 58% and 56% of patients, respectively, achieved at least a 4-point reduction in itch intensity at week 16 as measured by the Peak Pruritus Numerical Rating Scale, compared with 16% in both placebo groups (P < .0001). At the same time, 26% and 38% of nemolizumab-treated patients reached clearance or almost-clearance of skin lesions on the Investigator Global Assessment score at week 16, compared with 7% and 11% in the placebo groups (P < .0001).

According to the company press release, the most common side effects of nemolizumab are headache and rashes in the form of eczema, atopic dermatitis, and nummular eczema. 

“By inhibiting the signaling of IL-31, Nemluvio addresses a key driver of prurigo nodularis, safely and effectively improving itch as well as skin nodules,” Shawn G. Kwatra, MD, PhD, professor and chair of dermatology at the University of Maryland School of Medicine, Baltimore, and lead investigator of the OLYMPIA program, stated in the press release.

The regulatory submission of nemolizumab in atopic dermatitis is based on data from the phase 3 ARCADIA clinical trial program, which evaluated the efficacy and safety of nemolizumab administered subcutaneously every 4 weeks in adolescents and adults with moderate to severe atopic dermatitis. A decision on approval for this indication from the FDA is expected in December 2024.

In September 2022, dupilumab became the first FDA-approved treatment for PN in the United States.

Preexposure prophylaxis prescription reversals and abandonments were lower for patients seen by primary care clinicians than by other non–infectious disease clinicians, based on data from approximately 37,000 individuals.

Although preexposure prophylaxis (PrEP) has been associated with a reduced risk of HIV (human immunodeficiency virus) infection when used as prescribed, the association between PrEP prescription pickup and specialty of the prescribing clinician has not been examined, wrote Lorraine T. Dean, ScD, an epidemiologist at Johns Hopkins University, Baltimore, Maryland, and colleagues.

“HIV PrEP is highly effective at preventing new HIV cases, and while use is on the rise, is still used much less than it should be by people who are at risk of HIV,” Dr. Dean said in an interview. “This study is helpful in pinpointing who is at risk for not picking up PrEP and in helping us think through how to reach them so that they can be better positioned to get PrEP,” she said.

In a study published in JAMA Internal Medicine, the researchers reviewed data for PrEP care. The study population included 37,003 patients aged 18 years and older who received new insurer-approved PrEP prescriptions between 2015 and 2019. Most of the patients (77%) ranged in age from 25 to 64 years; 88% were male.

Pharmacy claims data were matched with clinician data from the US National Plan and Provider Enumeration System.

Clinicians were divided into three groups: primary care providers (PCPs), infectious disease specialists (IDs), and other specialists (defined as any clinician prescribing PrEP but not classified as a PCP or an ID specialist). The main binary outcomes were prescription reversal (defined as when a patient failed to retrieve a prescription) and abandonment (defined as when a patient neglected to pick up a prescription for 1 year).

Overall, of 24,604 patients 67% received prescriptions from PCPs, 3,571 (10%) received prescriptions from ID specialists, and 8828 (24%) received prescriptions from other specialty clinicians.

The prevalence of reversals for patients seen by PCPs, ID specialists, and other specialty clinicians was 18%, 18%, and 25%, respectively. The prevalence of abandonments by clinician group was 12%, 12%, and 20%, respectively.

In a regression analysis, patients prescribed PrEP by ID specialists had 10% lower odds of reversals and 12% lower odds of abandonments compared to those seen by PCPs (odds ratio 0.90 and 0.88, respectively). However, patients seen by other clinicians (not primary care or ID) were 33% and 54% more likely to have reversals and abandonments, respectively, compared with those seen by PCPs.

Many patients at risk for HIV first see a PCP and then are referred to a specialist, such as an ID physician, Dr. Dean said. “The patients who take the time to then follow up with a specialist may be most motivated and able to follow through with the specialist’s request, in this case, accessing their PrEP prescription,” she said. In the current study, the researchers were most surprised by how many other specialty providers are involved in PrEP care, which is very positive given the effectiveness of the medication, she noted.

“Our results suggest that a wide range of prescribers, regardless of specialty, should be equipped to prescribe PrEP as well as offer PrEP counseling,” Dr. Dean said. A key takeaway for clinicians is that PrEP should have no cost for the majority of patients in the United States, she emphasized. The absence of cost expands the population who should be interested and able to access PrEP, she said. Therefore, providers should be prepared to recommend PrEP to eligible patients, and seek training or continuing medical education for themselves so they feel equipped to prescribe and counsel patients on PrEP, she said.

“One limitation of this work is that, while it can point to what is happening, it cannot tell us why the reversals are happening; what is the reason patients prescribed by certain providers are more or less likely to get their PrEP,” Dr. Dean explained. “We have tried to do interviews with patients to understand why this might be happening, but it’s hard to find people who aren’t showing up to do something, compared to finding people who are showing up to do something,” she said. Alternatively, researchers could interview providers to understand their perspective on why differences in prescription pickups occur across specialties, she said.

Looking ahead, “a national PrEP program that includes elements of required clinician training could be beneficial, and research on how a national PrEP program could be implemented and impact HIV rates would be helpful in considering this strategy of prevention,” said Dr. Dean. 
 

Support All Prescribers to Increase PrEP Adherence

Differences in uptake of PrEP prescriptions may be explained by the different populations seen by various specialties, Meredith Green, MD, of Indiana University School of Medicine, Indianapolis, and Lona Mody, MD, of the University of Michigan, Ann Arbor, wrote in an accompanying editorial. However, the key question is how to support all prescribers and promote initiation and adherence to PrEP, they said.

Considerations include whether people at risk for HIV prefer to discuss PrEP with a clinician they already know, vs. a new specialist, but many PCPs are not familiar with the latest PrEP guidelines, they said.

“Interventions that support PrEP provision by PCPs, especially since they prescribed the largest proportion of PrEP prescriptions, can accelerate the uptake of PrEP,” the editorialists wrote.

“Supporting a diverse clinician workforce reflective of communities most impacted by HIV will remain critical, as will acknowledging and addressing HIV stigma,” they said. Educational interventions, including online programs and specialist access for complex cases, would help as well, they said. The approval of additional PrEP agents since the current study was conducted make it even more important to support PrEP prescribers and promote treatment adherence for those at risk for HIV, Dr. Green and Dr. Mody emphasized.

The study was funded by the National Institutes of Health. Dr. Dean had no financial conflicts to disclose. Dr. Green disclosed grants from Gilead and royalties from Wolters Kluwer unrelated to the current study; she also disclosed serving on the Centers for Disease Control and Prevention/Health Resources and Services Administration advisory committee on HIV, viral hepatitis, and sexually transmitted infection prevention and treatment. Dr. Mody disclosed grants from the US National Institute on Aging, Veterans Affairs, Centers for Disease Control and Prevention, NanoVibronix, and UpToDate unrelated to the current study.

Edema in the feet and legs is a common complaint in our practices. It can cause pain, weakness, heaviness, discomfort, limited movement, and a negative body image. Medications can contribute to edema, either alone or in combination with other health issues.

Edema is also associated with advanced age, female sex, obesity, diabetes, hypertension, pain, lack of physical activity, and mobility limitations. These factors often necessitate medication prescriptions, which can aggravate the problem. Therefore, it is important to know how to treat or prevent medication-induced edema.

There are four main causes of edema, and all can facilitate medication-induced edema.

• Increased capillary pressure. Conditions such as heart failure, renal dysfunction, venous insufficiency, deep vein thrombosis, and cirrhosis can increase capillary pressure, leading to edema.
• Decreased oncotic pressure. Hypoalbuminemia, a primary cause of reduced colloid oncotic pressure, can result from nephrotic syndrome, diabetic nephropathy, lupus nephropathy, amyloidosis, nephropathies, cirrhosis, chronic liver disease, and malabsorption or malnutrition.
• Increased capillary permeability. Vascular injury, often associated with diabetes, can increase capillary permeability and contribute to edema.
• Impaired lymphatic drainage. Lymphatic obstruction is common in patients with lymphedema, tumors, inflammation, fibrosis, certain infections, surgery, and congenital anomalies. Conditions such as thyroid disorders can also cause an increase in interstitial albumin and other proteins without a corresponding increase in lymphatic flow, leading to lymphedema.

Medications That Can Cause Edema

• Calcium channel blockers (CCBs). Drugs such as nifedipine and amlodipine can increase hydrostatic pressure by causing selective vasodilation of precapillary vessels, leading to increased intracapillary pressures. Newer lipophilic CCBs (eg, levamlodipine) exhibit lower rates of edema. Reducing the dose is often effective. Diuretics are not very effective for vasodilation-induced edema. Combining CCBs with angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), which induce postcapillary dilation and normalize intracapillary pressure, may reduce fluid leakage into the interstitial space. This combination may be more beneficial than high-dose CCB monotherapy.
• Thiazolidinedione (eg, pioglitazone). These increase vascular permeability and hydrostatic pressure. They work by stimulating the peroxisome proliferator–activated gamma receptor, increasing vascular endothelial permeability, vascular endothelial growth factor secretion, and renal retention of sodium and fluids. Because of other adverse effects, their use is now limited.
• Agents for neuropathic pain (gabapentin and pregabalin). These drugs can induce selective vasodilation of arterioles through a mechanism similar to that of CCBs, causing increased intracapillary pressures. Edema usually begins within the first month of treatment or dose increase and often regresses after dose reduction or drug discontinuation.
• Antiparkinsonian dopamine agonists. These increase hydrostatic pressure by reducing sympathetic tone and dilating arterioles through alpha-2 adrenergic receptor activity.
• New antipsychotics. Drugs like clozapine, iloperidone, lurasidone, olanzapine, quetiapine, risperidone, and ziprasidone can increase hydrostatic pressure through antagonistic effects on alpha-1 adrenergic receptors, causing vasodilation.
• Nitrates. These drugs increase hydrostatic pressure by causing preferential venous dilation, leading to increased venous pooling.
• Nonsteroidal anti-inflammatory drugs (NSAIDs). These drugs can increase hydrostatic pressure by inhibiting vasodilation of afferent renal arterioles, decreasing the glomerular filtration rate, and stimulating the renin-angiotensin-aldosterone system, which leads to sodium and water retention. These adverse effects warrant cautious use of these agents.
• ACE inhibitors. Drugs such as enalapril and ramipril can increase vascular permeability. They reduce the metabolism and accumulation of bradykinin, which increases vascular permeability and fluid leakage. These effects are rare and are usually related to allergic responses.
• Insulin. Insulin decreases capillary oncotic pressure and increases vascular permeability. Rapid correction of hyperglycemia can cause a loss of oncotic pressure, while chronic hyperglycemia can damage vascular membranes, increasing permeability. These effects are generally benign and can be managed with careful dose titration, sodium restriction, or diuretics.
• Steroids. Steroids with mineralocorticoid activity can increase renal sodium and water retention, leading to increased blood volume. Fludrocortisone has the highest mineralocorticoid activity, while dexamethasone and methylprednisolone have negligible activity.

Implications

Understanding how these medications cause edema is important for effective management. For example, in the case of those causing edema due to reduced oncotic pressure, like insulin, slow dose titrations can help adapt to osmolarity changes. For drugs causing edema due to increased hydrostatic pressure, diuretics are more effective in acute management.

The key takeaways from this review are:

• Awareness of drug-induced edema. Many drugs besides CCBs can cause edema.
• Combination therapy. Combining ACE inhibitors or ARBs with CCBs can prevent or reduce CCB-induced edema.
• Edema management strategies. Strategies to manage or prevent edema should include dose reductions or replacement of the problematic medication, especially in severe or refractory cases.

• ACE inhibitors. Drugs such as enalapril and ramipril can increase vascular permeability. They reduce the metabolism and accumulation of bradykinin, which increases vascular permeability and fluid leakage. These effects are rare and are usually related to allergic responses.
• Insulin. Insulin decreases capillary oncotic pressure and increases vascular permeability. Rapid correction of hyperglycemia can cause a loss of oncotic pressure, while chronic hyperglycemia can damage vascular membranes, increasing permeability. These effects are generally benign and can be managed with careful dose titration, sodium restriction, or diuretics.
• Steroids. Steroids with mineralocorticoid activity can increase renal sodium and water retention, leading to increased blood volume. Fludrocortisone has the highest mineralocorticoid activity, while dexamethasone and methylprednisolone have negligible activity.

Implications

Understanding how these medications cause edema is important for effective management. For example, in the case of those causing edema due to reduced oncotic pressure, like insulin, slow dose titrations can help adapt to osmolarity changes. For drugs causing edema due to increased hydrostatic pressure, diuretics are more effective in acute management.

The key takeaways from this review are:

• Awareness of drug-induced edema. Many drugs besides CCBs can cause edema.
• Combination therapy. Combining ACE inhibitors or ARBs with CCBs can prevent or reduce CCB-induced edema.
• Edema management strategies. Strategies to manage or prevent edema should include dose reductions or replacement of the problematic medication, especially in severe or refractory cases.

Edema in the feet and legs is a common complaint in our practices. It can cause pain, weakness, heaviness, discomfort, limited movement, and a negative body image. Medications can contribute to edema, either alone or in combination with other health issues.

Edema is also associated with advanced age, female sex, obesity, diabetes, hypertension, pain, lack of physical activity, and mobility limitations. These factors often necessitate medication prescriptions, which can aggravate the problem. Therefore, it is important to know how to treat or prevent medication-induced edema.

There are four main causes of edema, and all can facilitate medication-induced edema.

• Increased capillary pressure. Conditions such as heart failure, renal dysfunction, venous insufficiency, deep vein thrombosis, and cirrhosis can increase capillary pressure, leading to edema.
• Decreased oncotic pressure. Hypoalbuminemia, a primary cause of reduced colloid oncotic pressure, can result from nephrotic syndrome, diabetic nephropathy, lupus nephropathy, amyloidosis, nephropathies, cirrhosis, chronic liver disease, and malabsorption or malnutrition.
• Increased capillary permeability. Vascular injury, often associated with diabetes, can increase capillary permeability and contribute to edema.
• Impaired lymphatic drainage. Lymphatic obstruction is common in patients with lymphedema, tumors, inflammation, fibrosis, certain infections, surgery, and congenital anomalies. Conditions such as thyroid disorders can also cause an increase in interstitial albumin and other proteins without a corresponding increase in lymphatic flow, leading to lymphedema.

Medications That Can Cause Edema

• Calcium channel blockers (CCBs). Drugs such as nifedipine and amlodipine can increase hydrostatic pressure by causing selective vasodilation of precapillary vessels, leading to increased intracapillary pressures. Newer lipophilic CCBs (eg, levamlodipine) exhibit lower rates of edema. Reducing the dose is often effective. Diuretics are not very effective for vasodilation-induced edema. Combining CCBs with angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), which induce postcapillary dilation and normalize intracapillary pressure, may reduce fluid leakage into the interstitial space. This combination may be more beneficial than high-dose CCB monotherapy.
• Thiazolidinedione (eg, pioglitazone). These increase vascular permeability and hydrostatic pressure. They work by stimulating the peroxisome proliferator–activated gamma receptor, increasing vascular endothelial permeability, vascular endothelial growth factor secretion, and renal retention of sodium and fluids. Because of other adverse effects, their use is now limited.
• Agents for neuropathic pain (gabapentin and pregabalin). These drugs can induce selective vasodilation of arterioles through a mechanism similar to that of CCBs, causing increased intracapillary pressures. Edema usually begins within the first month of treatment or dose increase and often regresses after dose reduction or drug discontinuation.
• Antiparkinsonian dopamine agonists. These increase hydrostatic pressure by reducing sympathetic tone and dilating arterioles through alpha-2 adrenergic receptor activity.
• New antipsychotics. Drugs like clozapine, iloperidone, lurasidone, olanzapine, quetiapine, risperidone, and ziprasidone can increase hydrostatic pressure through antagonistic effects on alpha-1 adrenergic receptors, causing vasodilation.
• Nitrates. These drugs increase hydrostatic pressure by causing preferential venous dilation, leading to increased venous pooling.
• Nonsteroidal anti-inflammatory drugs (NSAIDs). These drugs can increase hydrostatic pressure by inhibiting vasodilation of afferent renal arterioles, decreasing the glomerular filtration rate, and stimulating the renin-angiotensin-aldosterone system, which leads to sodium and water retention. These adverse effects warrant cautious use of these agents.
• ACE inhibitors. Drugs such as enalapril and ramipril can increase vascular permeability. They reduce the metabolism and accumulation of bradykinin, which increases vascular permeability and fluid leakage. These effects are rare and are usually related to allergic responses.
• Insulin. Insulin decreases capillary oncotic pressure and increases vascular permeability. Rapid correction of hyperglycemia can cause a loss of oncotic pressure, while chronic hyperglycemia can damage vascular membranes, increasing permeability. These effects are generally benign and can be managed with careful dose titration, sodium restriction, or diuretics.
• Steroids. Steroids with mineralocorticoid activity can increase renal sodium and water retention, leading to increased blood volume. Fludrocortisone has the highest mineralocorticoid activity, while dexamethasone and methylprednisolone have negligible activity.

In the 18 months after Francine Milano was diagnosed with a recurrence of the ovarian cancer she thought she’d beaten 20 years ago, she traveled twice from her home in Pennsylvania to Vermont. She went not to ski, hike, or leaf-peep, but to arrange to die.

“I really wanted to take control over how I left this world,” said the 61-year-old who lives in Lancaster. “I decided that this was an option for me.”

Dying with medical assistance wasn’t an option when Ms. Milano learned in early 2023 that her disease was incurable. At that point, she would have had to travel to Switzerland — or live in the District of Columbia or one of the 10 states where medical aid in dying was legal.

But Vermont lifted its residency requirement in May 2023, followed by Oregon two months later. (Montana effectively allows aid in dying through a 2009 court decision, but that ruling doesn’t spell out rules around residency. And though New York and California recently considered legislation that would allow out-of-staters to secure aid in dying, neither provision passed.)

Despite the limited options and the challenges — such as finding doctors in a new state, figuring out where to die, and traveling when too sick to walk to the next room, let alone climb into a car — dozens have made the trek to the two states that have opened their doors to terminally ill nonresidents seeking aid in dying.

At least 26 people have traveled to Vermont to die, representing nearly 25% of the reported assisted deaths in the state from May 2023 through this June, according to the Vermont Department of Health. In Oregon, 23 out-of-state residents died using medical assistance in 2023, just over 6% of the state total, according to the Oregon Health Authority.

Oncologist Charles Blanke, MD, whose clinic in Portland is devoted to end-of-life care, said he thinks that Oregon’s total is likely an undercount and he expects the numbers to grow. Over the past year, he said, he’s seen two to four out-of-state patients a week — about one-quarter of his practice — and fielded calls from across the U.S., including New York, the Carolinas, Florida, and “tons from Texas.” But just because patients are willing to travel doesn’t mean it’s easy or that they get their desired outcome.

“The law is pretty strict about what has to be done,” Dr. Blanke said.

As in other states that allow what some call physician-assisted death or assisted suicide, Oregon and Vermont require patients to be assessed by two doctors. Patients must have less than six months to live, be mentally and cognitively sound, and be physically able to ingest the drugs to end their lives. Charts and records must be reviewed in the state; neglecting to do so constitutes practicing medicine out of state, which violates medical licensing requirements. For the same reason, the patients must be in the state for the initial exam, when they request the drugs, and when they ingest them.

State legislatures impose those restrictions as safeguards — to balance the rights of patients seeking aid in dying with a legislative imperative not to pass laws that are harmful to anyone, said Peg Sandeen, CEO of the group Death With Dignity. Like many aid-in-dying advocates, however, she said such rules create undue burdens for people who are already suffering.

Diana Barnard, MD, a Vermont palliative care physician, said some patients cannot even come for their appointments. “They end up being sick or not feeling like traveling, so there’s rescheduling involved,” she said. “It’s asking people to use a significant part of their energy to come here when they really deserve to have the option closer to home.”

Those opposed to aid in dying include religious groups that say taking a life is immoral, and medical practitioners who argue their job is to make people more comfortable at the end of life, not to end the life itself.

Anthropologist Anita Hannig, who interviewed dozens of terminally ill patients while researching her 2022 book, “The Day I Die: The Untold Story of Assisted Dying in America,” said she doesn’t expect federal legislation to settle the issue anytime soon. As the Supreme Court did with abortion in 2022, it ruled assisted dying to be a states’ rights issue in 1997.

During the 2023-24 legislative sessions, 19 states (including Ms. Milano’s home state of Pennsylvania) considered aid-in-dying legislation, according to the advocacy group Compassion & Choices. Delaware was the sole state to pass it, but the governor has yet to act on it.

Ms. Sandeen said that many states initially pass restrictive laws — requiring 21-day wait times and psychiatric evaluations, for instance — only to eventually repeal provisions that prove unduly onerous. That makes her optimistic that more states will eventually follow Vermont and Oregon, she said.

Ms. Milano would have preferred to travel to neighboring New Jersey, where aid in dying has been legal since 2019, but its residency requirement made that a nonstarter. And though Oregon has more providers than the largely rural state of Vermont, Ms. Milano opted for the 9-hour car ride to Burlington because it was less physically and financially draining than a cross-country trip.

The logistics were key because Ms. Milano knew she’d have to return. When she traveled to Vermont in May 2023 with her husband and her brother, she wasn’t near death. She figured that the next time she was in Vermont, it would be to request the medication. Then she’d have to wait 15 days to receive it.

The waiting period is standard to ensure that a person has what Dr. Barnard calls “thoughtful time to contemplate the decision,” although she said most have done that long before. Some states have shortened the period or, like Oregon, have a waiver option.

That waiting period can be hard on patients, on top of being away from their health care team, home, and family. Blanke said he has seen as many as 25 relatives attend the death of an Oregon resident, but out-of-staters usually bring only one person. And while finding a place to die can be a problem for Oregonians who are in care homes or hospitals that prohibit aid in dying, it’s especially challenging for nonresidents.

When Oregon lifted its residency requirement, Dr. Blanke advertised on Craigslist and used the results to compile a list of short-term accommodations, including Airbnbs, willing to allow patients to die there. Nonprofits in states with aid-in-dying laws also maintain such lists, Ms. Sandeen said.

Ms. Milano hasn’t gotten to the point where she needs to find a place to take the meds and end her life. In fact, because she had a relatively healthy year after her first trip to Vermont, she let her 6-month approval period lapse.

In June, though, she headed back to open another 6-month window. This time, she went with a girlfriend who has a camper van. They drove 6 hours to cross the state border, stopping at a playground and gift shop before sitting in a parking lot where Ms. Milano had a Zoom appointment with her doctors rather than driving 3 more hours to Burlington to meet in person.

“I don’t know if they do GPS tracking or IP address kind of stuff, but I would have been afraid not to be honest,” she said.

That’s not all that scares her. She worries she’ll be too sick to return to Vermont when she is ready to die. And, even if she can get there, she wonders whether she’ll have the courage to take the medication. About one-third of people approved for assisted death don’t follow through, Dr. Blanke said. For them, it’s often enough to know they have the meds — the control — to end their lives when they want.

Ms. Milano said she is grateful she has that power now while she’s still healthy enough to travel and enjoy life. “I just wish more people had the option,” she said.

As more data show potentially dangerous effects of climate and weather on individuals with chronic medical conditions, CVS Health has introduced an initiative that uses technology to provide weather alerts and targeted outreach to those at increased risk, according to a press release from the company. Ultimately, the goals of the initiative are to improve health, reduce emergency department visits, hospital stays, and medical costs, according to the press release.

Extreme weather events such as heat waves are becoming more frequent and severe, but most heat-related deaths are preventable with outreach and intervention, Dan Knecht, MD, vice president and chief clinical innovation officer for CVS Caremark, a division of CVS Health, said in an interview. The approach will combine the company’s services, including care managers, health centers, and data, to aid patients vulnerable to severe weather.

The initiative is starting with a focus on extreme heat events and will expand this fall with alerts about high levels of air pollution for individuals with vulnerability to reduced lung function, asthma, and cardiac problems as a result of exposure to high air-pollution levels, according to Dr. Knecht.

For now, the initiative is available to members of Aetna Medicare, according to Dr. Knecht. “Our goal is to expand to other consumers, including those who visit MinuteClinic and CVS Pharmacy locations, where we can provide timely environment-related recommendations at time of care,” he said.

The alert system uses environmental data analytics to pair highly localized forecasts and real-time insights about air quality, wildfires, and high heat with medical and pharmacy data for high-risk patients in areas affected by extreme weather.

For example, for individuals who are at risk and living in areas facing extreme heat, “registered nurse care managers proactively reach out to vulnerable patients up to several days in advance of an extreme weather event and provide them personalized tips and resources,” said Dr. Knecht.

In addition, he added, “we talk to patients about how to manage their medications during periods of extreme heat and, when delivering medications, take weather data into account to determine appropriate packaging materials for shipments.”

These interventions direct patients to CVS Health–linked resources, such as Oak Street Health clinics available as cooling centers, health services provided at MinuteClinic locations, and medication management at CVS pharmacies. Other interventions include virtual or in-person mental health counseling through MinuteClinic.

Dr. Knecht offered additional guidance for clinicians and patients to help manage heat waves. “Heat and certain medications can impair heat tolerance and the ability to regulate body temperature,” he told this news organization. Extreme heat may affect the performance of some medications and their devices, such as inhalers and diabetes supplies, he added.
 

Health Alerts Have Potential, But Comprehensive Approach is Needed

“Patients with chronic lung conditions are highly susceptible to the impact of climate change,” MeiLan K. Han, MD, a pulmonologist and professor of internal medicine at the University of Michigan, Ann Arbor, said in an interview. “Increasing dust, hotter temperatures, and higher levels of air pollution make it more difficult for patients to breathe,” she said. Data also suggest that higher levels of air pollution may not only cause chronic lung disease but also cause worsening symptoms among those with existing disease, she added.

A weather-related health alert could be useful for patients so they can be prepared, Dr. Han told this news organization.

“For a patient with chronic lung disease, a hot weather alert may mean that it will be harder for patients to breathe, and [they] may [be] more susceptible to heat stroke and dehydration if they do not have access to air conditioning,” she said. “At a minimum, patients should ensure they are on their controller medications, which often means a daily inhaler for patients with conditions such as asthma and chronic obstructive pulmonary disease (COPD). However, patients also should have access to their short-term reliever medications so they can be prepared for increased shortness of breath that may accompany a hot weather day,” Dr. Han explained.

However, not all patients have access to technology such as smartphones or other devices that will alert them to impending weather events, such as heat waves, said Dr. Han. “For these patients, a standard phone call may be beneficial,” she said.

Looking ahead, “programs for weather-related health alerts will need to be comprehensive, focusing not only on access to needed medications but also climate-controlled settings for temporary relief of heat,” said Dr. Han. “For some of our most vulnerable patients, while they may have air conditioning, they may not be able to afford to run it, so this needs to be considered in developing a comprehensive program,” she emphasized.

As more data show potentially dangerous effects of climate and weather on individuals with chronic medical conditions, CVS Health has introduced an initiative that uses technology to provide weather alerts and targeted outreach to those at increased risk, according to a press release from the company. Ultimately, the goals of the initiative are to improve health, reduce emergency department visits, hospital stays, and medical costs, according to the press release.

Extreme weather events such as heat waves are becoming more frequent and severe, but most heat-related deaths are preventable with outreach and intervention, Dan Knecht, MD, vice president and chief clinical innovation officer for CVS Caremark, a division of CVS Health, said in an interview. The approach will combine the company’s services, including care managers, health centers, and data, to aid patients vulnerable to severe weather.

The initiative is starting with a focus on extreme heat events and will expand this fall with alerts about high levels of air pollution for individuals with vulnerability to reduced lung function, asthma, and cardiac problems as a result of exposure to high air-pollution levels, according to Dr. Knecht.

For now, the initiative is available to members of Aetna Medicare, according to Dr. Knecht. “Our goal is to expand to other consumers, including those who visit MinuteClinic and CVS Pharmacy locations, where we can provide timely environment-related recommendations at time of care,” he said.

The alert system uses environmental data analytics to pair highly localized forecasts and real-time insights about air quality, wildfires, and high heat with medical and pharmacy data for high-risk patients in areas affected by extreme weather.

For example, for individuals who are at risk and living in areas facing extreme heat, “registered nurse care managers proactively reach out to vulnerable patients up to several days in advance of an extreme weather event and provide them personalized tips and resources,” said Dr. Knecht.

In addition, he added, “we talk to patients about how to manage their medications during periods of extreme heat and, when delivering medications, take weather data into account to determine appropriate packaging materials for shipments.”

These interventions direct patients to CVS Health–linked resources, such as Oak Street Health clinics available as cooling centers, health services provided at MinuteClinic locations, and medication management at CVS pharmacies. Other interventions include virtual or in-person mental health counseling through MinuteClinic.

Dr. Knecht offered additional guidance for clinicians and patients to help manage heat waves. “Heat and certain medications can impair heat tolerance and the ability to regulate body temperature,” he told this news organization. Extreme heat may affect the performance of some medications and their devices, such as inhalers and diabetes supplies, he added.
 

Health Alerts Have Potential, But Comprehensive Approach is Needed

“Patients with chronic lung conditions are highly susceptible to the impact of climate change,” MeiLan K. Han, MD, a pulmonologist and professor of internal medicine at the University of Michigan, Ann Arbor, said in an interview. “Increasing dust, hotter temperatures, and higher levels of air pollution make it more difficult for patients to breathe,” she said. Data also suggest that higher levels of air pollution may not only cause chronic lung disease but also cause worsening symptoms among those with existing disease, she added.

A weather-related health alert could be useful for patients so they can be prepared, Dr. Han told this news organization.

Having an ostomy is a dreaded prospect for many patients with rectal cancer.

To defer, and potentially avoid, this life-altering surgery, the watch-and-wait approach has become increasingly common among patients with locally advanced disease who have a complete response to neoadjuvant chemoradiation.

About 80% of these patients who have a complete clinical response — a perfectly healed scar where the tumor used to be and other favorable features — can forgo total mesorectal excision and preserve their rectum.

The success of watch-and-wait among complete responders has led some centers to offer the approach in patients with near-complete responses to neoadjuvant chemoradiation.

But watch-and-wait for near-complete clinical responders “is very controversial,” Alan P. Venook, MD, a gastrointestinal oncologist at the University of California, San Francisco (UCSF), told this news organization.

“You sure as hell don’t want to miss a chance to cure a patient,” Dr. Venook said.

A near-complete clinical response essentially means there is no sign of the tumor 8 weeks after total neoadjuvant therapy, but the tumor bed hasn’t completely healed.

The goal of watch-and-wait in this scenario is to give near-complete response lesions time to become complete responses.

But there’s no clear way to predict which tumors will evolve into a clinical complete response.

Recent studies evaluating the conversion rate have reported that anywhere from 39% to about 90% of near-complete responders became complete responders. Some of the variation likely comes down to differences in the clinical stage of patients evaluated in each study as well as the limited number of patients who achieve a near-complete response overall.

Other concerns have emerged that waiting for near-complete responses to become complete leaves extra time for some tumors to metastasize and that tumor regrowth is much higher compared with complete responders.

A recent study found that 13% of near-complete responders who preserved their rectum on watch-and-wait developed distant metastases vs about 5% of long-term complete responders. The study also found that just over half of near-complete responders have tumor regrowth compared with about one in five complete responders.

But even with regrowth, “surgery is still curative,” explained Julio Garcia-Aguilar, MD, PhD, a pioneer of watch-and-wait for rectal cancer.

And overall, around 50%-60% of patients with a near-complete response can avoid surgery and preserve their rectum.
 

Selecting Patients for Watch-and-Wait

The key to deciding which patients are right for watch-and-wait is to understand how a near-complete clinical response was defined in the OPRA trial, a landmark randomized trial led by Dr. Garcia-Aguilar that helped establish watch-and-wait as an option in rectal cancer.

OPRA defined a near-complete response as no visible tumor but, in the tumor bed, mild erythema, superficial ulceration, minor mucosal abnormality or small nodules, and an irregular mucosa. The criteria also included no palpable tumor with smooth induration or a minor mucosal abnormality on the digital rectal exam.

The National Comprehensive Cancer Network mirrored the definition when, for the first time, it recommended watch-and-wait as an option for near-complete response in its 2023 rectal cancer guidelines. The group also added a few MRI requirements.

UCSF offers the watch-and-wait option to some patients with near-complete responses, but each decision is made on a case-by-case basis by a tumor board considering numerous measures of tumor aggressiveness.

Even then, “we have, in many cases, struggled to figure out what the right choices are,” Dr. Venook said.

For those chosen for watch-and-wait, Dr. Venook noted that UCSF has top-notch surgeons, radiation oncologists, medical oncologists, and pathologists who have the resources to follow patients closely.

For community practices without the resources of a major cancer center, watch-and-wait for near-complete response to rectal cancer “is really asking a lot,” Dr. Venook said.

Dr. Garcia-Aguilar, a colorectal surgeon at Memorial Sloan Kettering Cancer Center in New York City, explained that after years of studying the issue, he is comfortable with watch-and-wait in near-complete responders as long as it’s done carefully and in patients who will comply with ongoing surveillance.

Dr. Garcia-Aguilar explained that, after diagnosing a near-complete response 8 weeks following total neoadjuvant therapy, the patient needs to come back 6 weeks later. At that point, it’s time to assess whether that near-complete response is evolving into a complete response or not evolving into a complete response.

If it’s evolving into a complete response, surveillance continues about every 8 weeks, but if the tumor has stopped responding, “you take [the patient] to the operating room,” Dr. Garcia-Aguilar said.

As for the bigger safety concern — that near clinical complete response tumors will metastasize — Dr. Garcia-Aguilar’s opinion is that micrometastases are probably already there when the rectal cancer is first diagnosed and will manifest themselves “no matter what happens to the primary tumor.”

Because of that, he noted, “I don’t think the risk is very high” when surgery is delayed a few months to give near-complete response patients a chance to keep their rectum.

The way to answer the metastasis question is to do a randomized trial pitting surgery against watch-and-wait in patients with near-clinical complete response rectal cancer.

However, Dr. Garcia-Aguilar doesn’t think that trial will ever happen. Patients won’t allow themselves to be randomized to surgery once they find out they might be able to avoid a permanent ostomy, he said.

Dr. Venook had no disclosures. Dr. Garcia-Aguilar reported personal fees from Medtronic, Johnson & Johnson, and Intuitive Surgical.

STOCKHOLM — At the American Society of Retina Specialists (ASRS) 2024 Annual Meeting, researchers discussed how insights into potential risk factors and new treatments could improve outcomes for patients with diabetic retinopathy.

Jennifer Lim, MD, an ophthalmologist and director of the Retina Service at the University of Illinois Hospital & Health Sciences System in Chicago, told this news organization that emerging approaches to treating diabetic retinopathy offer hope because they address the root causes of the disease beyond just targeting vascular endothelial growth factor (VEGF). She said innovative methods and add-on treatments could lead to more durable and effective drugs.

Exploration of risk factors and treatment options for diabetic retinopathy could lead to more effective management strategies for the condition, agreed David Boyer, MD, an ophthalmologist at Retina Vitreous Associates Medical Group in Los Angeles, speaking with this news organization.
 

Risk Factors for Diabetic Retinopathy

Sodium-glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide 1 receptor agonists (GLP-1 RAs) have gained popularity because of their benefits beyond glycemic control, including weight loss, and cardiovascular and kidney protection. However, the impact of these medications on vision-threatening retinal complications is not fully understood. “There has always been a question about whether these newer diabetes medications might exacerbate diabetic eye disease,” said Dr. Boyer.

In a retrospective observational study, researchers included adults with type 2 diabetes and moderate cardiovascular disease risk who had no history of advanced diabetic retinal complications. These patients initiated treatment with GLP-1 RA, SGLT2 inhibitors, DPP-4 inhibitors, or sulfonylureas. The study used inverse probability of treatment weighting to mimic randomization and compared the time to the first treatment for diabetic macular edema or proliferative diabetic retinopathy across the treatment groups.

Results, presented by Andrew J. Barkmeier, MD, an associate professor of ophthalmology at the Mayo Clinic, showed that among 371,698 patients, those who initiated therapy with SGLT2 inhibitors had a lower risk of requiring treatment for sight-threatening retinopathy compared with those using other medication classes. GLP-1 RA did not increase retinopathy risk relative to dipeptidyl peptidase 4 inhibitors and sulfonylurea medications.

“[This study] told us that we do have to keep an eye on patients’ retinopathy when they start on these new inhibitors. But the progression is minimal and, overall, I think most people today favor keeping blood sugar levels as good as possible,” said Dr. Boyer, who was not involved in the study.

Another factor that might increase diabetic retinopathy progression is obstructive sleep apnea. This underdiagnosed condition is linked to several health issues, including dementia, stroke, and myocardial infarctions. Although not easily treated, obstructive sleep apnea is manageable, Dr. Boyer explained.

Researchers utilized the TriNetX electronic health records research network to identify patients with nonproliferative diabetic retinopathy, both with and without obstructive sleep apnea. 

The results, presented by Ehsan Rahimy, MD, a retinal specialist at Palo Alto Medical Foundation and a professor at Stanford University, showed that patients with obstructive sleep apnea had a significantly higher risk of progressing to proliferative diabetic retinopathy and developing new-onset diabetic macular edema. These patients were more likely to require ocular interventions, such as intravitreal injections and laser photocoagulation. They also had greater risks for stroke, myocardial infarction, and death compared with those who did not have obstructive sleep apnea.

“It was good to bring this to everybody’s attention,” said Dr. Boyer, who was not involved in the study. “It’s an easy question to ask someone if they snore.”
 

New Treatments on the Horizon

In another presentation, Nathan C. Steinle, MD, of California Retina Consultants, presented a study that assessed the durability of response to sozinibercept in patients with retinal vascular diseases. This novel therapeutic agent is designed to inhibit VEGF-C and VEGF-D in conditions where VEGF-A suppression alone is insufficient. 

Sozinibercept was combined with standard anti–VEGF-A therapies such as ranibizumab or aflibercept. It involved a prospective, post hoc analysis of two phase 1b, open-label, dose-escalation studies, including 40 patients with neovascular age-related macular degeneration (nAMD; 31 patients) or diabetic macular edema (nine patients). These patients, either treatment-naive or previously treated, received three intravitreal injections of ranibizumab or aflibercept in combination with sozinibercept at various doses.

Results indicated that sozinibercept combination therapy was well tolerated, with no dose-limiting toxicities. In treatment-naive nAMD patients, the mean best-corrected visual acuity (BCVA) improved significantly from baseline at months 3 and 6. Previously treated nAMD patients also showed BCVA improvements, although to a lesser extent. For patients with persistent diabetic macular edema, switching to sozinibercept plus aflibercept resulted in notable BCVA gains. The mean time to requiring retreatment was longer in treatment-naive patients than in those previously treated, indicating a durable response. 

“Combination therapy with sozinibercept is going to be really important,” said Dr. Lim, who was not involved in the study, “because it attacks with a dual mechanism of action.”

Oral agents promise a potentially easier alternative for patients compared with frequent injections. CU06-1004 is a novel orally administered endothelial dysfunction blocker that has shown promise in stabilizing damaged capillaries, reducing abnormal angiogenesis, and inhibiting inflammatory activation in preclinical studies. “CU06 is very interesting to me because by preventing endothelial loss, it gets to the pathophysiology of why the blood vessels break down,” Dr. Lim said.

In a proof-of-concept phase 2a, multicenter, open-label, parallel-group trial, investigators randomly assigned 67 patients with diabetic macular edema to receive 100 mg, 200 mg, or 300 mg of CU06-1004 once daily for 12 weeks, followed by a 4-week follow-up. 

Results presented by Victor Gonzalez, MD, of Valley Retina Institute in Texas, indicated that the oral agent improved BCVA, stabilized central subfield thickness, and showed positive anatomical changes in optical coherence tomography images. CU06-1004 was well tolerated, with no drug-related serious adverse events. 

“The number [of patients] was very small, and we will need a much longer, larger trial to see if [CU06-1004] has benefits long term,” said Dr. Boyer, who was not involved in the study. “But I think we’re all very excited if we can find an oral agent for treating diabetic retinopathy. It would be easier for the patient to take a pill than having to come in for injections.” 

The sustained-release axitinib implant, OTX-TKI, is also generating significant interest, particularly for nonproliferative diabetic retinopathy. Axitinib, a tyrosine kinase inhibitor (TKI), targets signaling pathways crucial in cellular processes, providing a novel approach to managing diseases where traditional therapies might fall short. Unlike traditional anti-VEGF treatments that focus solely on cytokine levels, TKIs block the activation of signaling pathways, preventing downstream signaling regardless of cytokine levels. This mechanism is particularly important because it effectively inhibits disease progression even if levels of VEGF are high, Dr. Lim explained.

In the phase 1 HELIOS trial, OTX-TKI was assessed in patients with nonproliferative diabetic retinopathy. This multicenter, double-masked, parallel-group clinical study included 21 patients who had not received anti-VEGF treatment, dexamethasone intravitreal implants in the previous 12 months, or intraocular steroid injections in the prior 4 months. Patients were randomly assigned to receive either OTX-TKI or sham treatment.

Results presented by Dilsher S. Dhoot, MD, of California Retina Consultants, indicated that OTX-TKI was generally well tolerated, with no serious ocular adverse events. At 48 weeks, 46.2% of eyes treated with OTX-TKI showed a 1- or 2-step improvement on the Diabetic Retinopathy Severity Scale (DRSS) compared with none in the sham arm. Additionally, no eyes treated with OTX-TKI experienced a worsening on the DRSS, whereas 25% of eyes in the sham arm did. Vision-threatening complications, such as proliferative diabetic retinopathy or diabetic macular edema, developed in 37.5% of the sham group but in none of the OTX-TKI treated eyes. A single injection of OTX-TKI provided durable DRSS improvement for up to 48 weeks, with no patients in either arm requiring rescue therapy.

“This is a really exciting add-on treatment,” Dr. Lim said, who was not involved in the study. She explained that it is initially necessary to control the disease with standard treatments, because TKIs may take longer to exhibit their effects. Once the disease is stabilized, TKIs can be used alongside other therapies, potentially reducing the reliance on frequent anti-VEGF injections. “These are preliminary results, but that’s the hope going forward.”

STOCKHOLM — At the American Society of Retina Specialists (ASRS) 2024 Annual Meeting, researchers discussed how insights into potential risk factors and new treatments could improve outcomes for patients with diabetic retinopathy.

Jennifer Lim, MD, an ophthalmologist and director of the Retina Service at the University of Illinois Hospital & Health Sciences System in Chicago, told this news organization that emerging approaches to treating diabetic retinopathy offer hope because they address the root causes of the disease beyond just targeting vascular endothelial growth factor (VEGF). She said innovative methods and add-on treatments could lead to more durable and effective drugs.

Exploration of risk factors and treatment options for diabetic retinopathy could lead to more effective management strategies for the condition, agreed David Boyer, MD, an ophthalmologist at Retina Vitreous Associates Medical Group in Los Angeles, speaking with this news organization.
 

Risk Factors for Diabetic Retinopathy

Sodium-glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide 1 receptor agonists (GLP-1 RAs) have gained popularity because of their benefits beyond glycemic control, including weight loss, and cardiovascular and kidney protection. However, the impact of these medications on vision-threatening retinal complications is not fully understood. “There has always been a question about whether these newer diabetes medications might exacerbate diabetic eye disease,” said Dr. Boyer.

In a retrospective observational study, researchers included adults with type 2 diabetes and moderate cardiovascular disease risk who had no history of advanced diabetic retinal complications. These patients initiated treatment with GLP-1 RA, SGLT2 inhibitors, DPP-4 inhibitors, or sulfonylureas. The study used inverse probability of treatment weighting to mimic randomization and compared the time to the first treatment for diabetic macular edema or proliferative diabetic retinopathy across the treatment groups.

Results, presented by Andrew J. Barkmeier, MD, an associate professor of ophthalmology at the Mayo Clinic, showed that among 371,698 patients, those who initiated therapy with SGLT2 inhibitors had a lower risk of requiring treatment for sight-threatening retinopathy compared with those using other medication classes. GLP-1 RA did not increase retinopathy risk relative to dipeptidyl peptidase 4 inhibitors and sulfonylurea medications.

“[This study] told us that we do have to keep an eye on patients’ retinopathy when they start on these new inhibitors. But the progression is minimal and, overall, I think most people today favor keeping blood sugar levels as good as possible,” said Dr. Boyer, who was not involved in the study.

Another factor that might increase diabetic retinopathy progression is obstructive sleep apnea. This underdiagnosed condition is linked to several health issues, including dementia, stroke, and myocardial infarctions. Although not easily treated, obstructive sleep apnea is manageable, Dr. Boyer explained.

Researchers utilized the TriNetX electronic health records research network to identify patients with nonproliferative diabetic retinopathy, both with and without obstructive sleep apnea. 

The results, presented by Ehsan Rahimy, MD, a retinal specialist at Palo Alto Medical Foundation and a professor at Stanford University, showed that patients with obstructive sleep apnea had a significantly higher risk of progressing to proliferative diabetic retinopathy and developing new-onset diabetic macular edema. These patients were more likely to require ocular interventions, such as intravitreal injections and laser photocoagulation. They also had greater risks for stroke, myocardial infarction, and death compared with those who did not have obstructive sleep apnea.

“It was good to bring this to everybody’s attention,” said Dr. Boyer, who was not involved in the study. “It’s an easy question to ask someone if they snore.”
 

New Treatments on the Horizon

In another presentation, Nathan C. Steinle, MD, of California Retina Consultants, presented a study that assessed the durability of response to sozinibercept in patients with retinal vascular diseases. This novel therapeutic agent is designed to inhibit VEGF-C and VEGF-D in conditions where VEGF-A suppression alone is insufficient. 

Sozinibercept was combined with standard anti–VEGF-A therapies such as ranibizumab or aflibercept. It involved a prospective, post hoc analysis of two phase 1b, open-label, dose-escalation studies, including 40 patients with neovascular age-related macular degeneration (nAMD; 31 patients) or diabetic macular edema (nine patients). These patients, either treatment-naive or previously treated, received three intravitreal injections of ranibizumab or aflibercept in combination with sozinibercept at various doses.

Results indicated that sozinibercept combination therapy was well tolerated, with no dose-limiting toxicities. In treatment-naive nAMD patients, the mean best-corrected visual acuity (BCVA) improved significantly from baseline at months 3 and 6. Previously treated nAMD patients also showed BCVA improvements, although to a lesser extent. For patients with persistent diabetic macular edema, switching to sozinibercept plus aflibercept resulted in notable BCVA gains. The mean time to requiring retreatment was longer in treatment-naive patients than in those previously treated, indicating a durable response. 

“Combination therapy with sozinibercept is going to be really important,” said Dr. Lim, who was not involved in the study, “because it attacks with a dual mechanism of action.”

Oral agents promise a potentially easier alternative for patients compared with frequent injections. CU06-1004 is a novel orally administered endothelial dysfunction blocker that has shown promise in stabilizing damaged capillaries, reducing abnormal angiogenesis, and inhibiting inflammatory activation in preclinical studies. “CU06 is very interesting to me because by preventing endothelial loss, it gets to the pathophysiology of why the blood vessels break down,” Dr. Lim said.

In a proof-of-concept phase 2a, multicenter, open-label, parallel-group trial, investigators randomly assigned 67 patients with diabetic macular edema to receive 100 mg, 200 mg, or 300 mg of CU06-1004 once daily for 12 weeks, followed by a 4-week follow-up. 

Results presented by Victor Gonzalez, MD, of Valley Retina Institute in Texas, indicated that the oral agent improved BCVA, stabilized central subfield thickness, and showed positive anatomical changes in optical coherence tomography images. CU06-1004 was well tolerated, with no drug-related serious adverse events. 

“The number [of patients] was very small, and we will need a much longer, larger trial to see if [CU06-1004] has benefits long term,” said Dr. Boyer, who was not involved in the study. “But I think we’re all very excited if we can find an oral agent for treating diabetic retinopathy.

Take a look at any of the evidence-based US obesity treatment guidelines. The key criteria for diagnosing overweight and obesity is based on the body mass index (BMI). 

The guidelines also use BMI to stratify care options to decrease cardiovascular risk. For example, persons with BMI ≥30 are classified as having obesity, and antiobesity medications are recommended. Those with BMI ≥ 40 are classified as having severe obesity, and metabolic bariatric surgery may be appropriate. 

But where did these cutoff points for more and less aggressive treatments come from? These BMI cutoffs are based primarily on mortality data collected from large non-Hispanic White populations, without data on potential differences by gender and ethnicity. In fact, by itself, BMI is an incomplete measure of cardiometabolic risk, especially in a multiethnic clinic with all genders represented.

For example, it is certainly true that those with BMI ≥ 30 have more cardiovascular risk factors than those with BMI < 30. But Asian American individuals have more risk factors at lower BMIs than do White or African American individuals likely because of more visceral fat accumulation at lower BMIs.

Besides the variation in gender and ethnicity, BMI does not take the type and location of body fat into consideration. Adipose tissue in visceral or ectopic areas have much higher risks for disease than subcutaneous adipose tissue because of the associated inflammation. Measures such as waist circumference, waist-to-hip ratio, and skinfold measurements aim to capture this aspect but often fall short because of variation in techniques.

BMI does not account for muscle mass either, so fit athletes and bodybuilders can be classified as having obesity by BMI alone. More accurate body fat percent measures, such as dual-energy X-ray absorptiometry or MRI specifically for ectopic fat, are labor intensive, expensive, and not feasible to perform in a busy primary care or endocrinology clinic.
 

Assessing Risks From Obesity Beyond BMI

Clearly, better risk measures than BMI are needed, but until they are available, supplemental clinical tools can aid diagnosis and treatment decisions at obesity medicine specialty centers, endocrinology and diabetes centers, and those centers that focus on the treatment of obesity.

For example, a seca scale can measure percent body fat by bioelectric impedance analysis. This technique also has its limitations, but for persons who are well hydrated, it can be used as a baseline to determine efficacy of behavioral interventions, such as resistance-exercise training and a high-protein diet to protect muscle mass as the patient loses weight.

A lot also can be gleaned from diet and exercise history, social history, family history, and physical exam as well as laboratory analyses. For example, an Asian American patient with a BMI of 26 who has been gaining weight mostly in the abdominal region after age 35 years is likely to have cardiometabolic risk, and a family history can solidify that. An exam can show signs of acanthosis nigricans or an enlarged liver and generous abdominal adipose tissue. This would be the patient in whom you would want to obtain a hemoglobin A1c measurement in the chance that it is elevated at > 5.7 mg/dL, suggesting high risk for type 2 diabetes. 

A Fibrosis-4 score can assess the risk for liver disease from aspartate transaminase and alanine aminotransferase and platelet count and age, providing clues to cardiometabolic disease risk.

In the next 10, years there may be a better measure for cardiometabolic risk that is more accurate than BMI is. It could be the sagittal abdominal diameter, which has been purported to more accurately measure visceral abdominal fat. But this has not made it to be one of the vital signs in a busy primary care clinic, however. 
 

Will New Body Fat Tools Change Practice?

In the next 10 years, there may be an affordable gadget to scan the body to determine visceral vs subcutaneous deposition of fat — like radiography for tissue. Now, three-dimensional (3D) total-body scanners can obtain body composition, but they are extremely expensive. The more important clinical question is: How will the use of these imaging modalities change your practice protocol for a particular patient? 

Think about the FibroScan, a type of ultrasound used to determine fatty liver disease and fibrosis. We order the test for those patients in whom we already have a strong suspicion for liver disease and, in obesity practices, for fatty liver and metabolic-associated fatty liver disease or metabolic associated steatohepatitis.

The test results do much to educate the patient and help the patient understand the need for aggressive treatment for their obesity. But it doesn’t necessarily change the clinician’s practice protocols and decisions. We would still recommend weight management and medications or surgery to patients regardless of the findings. 

A FibroScan is an expense, and not all primary care or endocrine practitioners may feel it necessary to purchase one for the added benefit of patient education. And I would argue that a 3D body scanner is a great tool but more for educational purposes than to really determine practice decision-making or outcomes. 

In the meantime, an old-fashioned physical examination, along with a thorough medical, social, and family history should give even the busiest primary care provider enough information to decide whether their patient is a candidate for preventive measures to reduce body fat with diet, exercise, and medication as well as whether the patient is a candidate for metabolic bariatric surgery. Higher suspicion of cardiovascular risk at lower BMI ranges for various ethnicities can help primary care providers pick up on the patients with low BMI but who are at higher risk for type 2 diabetes or prediabetes and cardiovascular disease. 

So the answer to whether we need a better measure than the BMI: Yes, we do. We need a physical examination on all patients.

This technique also has its limitations, but for persons who are well hydrated, it can be used as a baseline to determine efficacy of behavioral interventions, such as resistance-exercise training and a high-protein diet to protect muscle mass as the patient loses weight.

A lot also can be gleaned from diet and exercise history, social history, family history, and physical exam as well as laboratory analyses. For example, an Asian American patient with a BMI of 26 who has been gaining weight mostly in the abdominal region after age 35 years is likely to have cardiometabolic risk, and a family history can solidify that. An exam can show signs of acanthosis nigricans or an enlarged liver and generous abdominal adipose tissue. This would be the patient in whom you would want to obtain a hemoglobin A1c measurement in the chance that it is elevated at > 5.7 mg/dL, suggesting high risk for type 2 diabetes. 

A Fibrosis-4 score can assess the risk for liver disease from aspartate transaminase and alanine aminotransferase and platelet count and age, providing clues to cardiometabolic disease risk.

In the next 10, years there may be a better measure for cardiometabolic risk that is more accurate than BMI is. It could be the sagittal abdominal diameter, which has been purported to more accurately measure visceral abdominal fat. But this has not made it to be one of the vital signs in a busy primary care clinic, however. 
 

Will New Body Fat Tools Change Practice?

In the next 10 years, there may be an affordable gadget to scan the body to determine visceral vs subcutaneous deposition of fat — like radiography for tissue. Now, three-dimensional (3D) total-body scanners can obtain body composition, but they are extremely expensive. The more important clinical question is: How will the use of these imaging modalities change your practice protocol for a particular patient? 

Think about the FibroScan, a type of ultrasound used to determine fatty liver disease and fibrosis. We order the test for those patients in whom we already have a strong suspicion for liver disease and, in obesity practices, for fatty liver and metabolic-associated fatty liver disease or metabolic associated steatohepatitis.

The test results do much to educate the patient and help the patient understand the need for aggressive treatment for their obesity. But it doesn’t necessarily change the clinician’s practice protocols and decisions. We would still recommend weight management and medications or surgery to patients regardless of the findings. 

A FibroScan is an expense, and not all primary care or endocrine practitioners may feel it necessary to purchase one for the added benefit of patient education. And I would argue that a 3D body scanner is a great tool but more for educational purposes than to really determine practice decision-making or outcomes. 

In the meantime, an old-fashioned physical examination, along with a thorough medical, social, and family history should give even the busiest primary care provider enough information to decide whether their patient is a candidate for preventive measures to reduce body fat with diet, exercise, and medication as well as whether the patient is a candidate for metabolic bariatric surgery. Higher suspicion of cardiovascular risk at lower BMI ranges for various ethnicities can help primary care providers pick up on the patients with low BMI but who are at higher risk for type 2 diabetes or prediabetes and cardiovascular disease. 

So the answer to whether we need a better measure than the BMI: Yes, we do. We need a physical examination on all patients.

The allegations against Algerian boxer Imane Khelif at the Paris Olympics raised the questions of intersexuality and its implications in competitive sports. This news organization has decided to delve into the topic to assist doctors who suspect a similar condition in their patients. No certain clinical data about Ms. Khelif have been made public, so this article does not concern the boxer but rather takes inspiration from the media controversy.

What Is Intersexuality?

Intersexuality encompasses a spectrum of variations in sexual development that lead to the simultaneous presence of typical male and female characteristics. As reiterated by the United Nations Office of the High Commissioner for Human Rights, the medical definition does not affect the patient’s self-identification of gender or sexual orientation.

“The percentage of people who fall within the intersexuality spectrum is less than 0.5 per thousand of the general population, but there are no precise statistics, given the difficulty of definition,” said Roberto Lala, MD, pediatric endocrinologist and president of the Federation of Rare Childhood Diseases.

Indeed, there is not only a strict definition of intersexuality that involves a significant presence of these mixed physical characteristics in a way that conditions the self-image of the subject but also a broad definition, said Dr. Lala. “For example, clitoral hypertrophy in a female otherwise conforming to the female gender, which does not raise doubts about identity,” he said.
 

Chromosomes, Genes, and Hormones

A patient’s sexual characteristics are determined by the complex interaction of chromosomal, genetic, and hormonal factors. “The human body is, so to speak, programmed to take on female appearances in development and shifts toward male ones only if exposed to testosterone and other factors. For this to happen, testosterone must be produced during embryonic development, and it must function properly,” said Paolo Moghetti, full professor of endocrinology at the University of Verona, Italy.

The protein encoded by SRY, which is located on the Y chromosome, determines the development of the testicles from undifferentiated tissue of the embryonic gonads. The testicles of the embryo then produce testosterone. The absence of the Y chromosome is a common characteristic of most female individuals. However, there are individuals with a female phenotype who have X and Y chromosomes but lack SRY or have a variant of it that is not entirely functional.

Numerous other chromosomal or genetic variations can lead to alterations in sexual differentiation. “In phenotypically male adult subjects (with a chromosomal makeup of 46XY) with complete androgen insensitivity (so-called Morris syndrome), testosterone levels in the blood are elevated, above normal even for a male, but the hormone is totally ineffective, and the phenotype is totally female at birth, with completely female development of secondary sexual characteristics at puberty,” said Dr. Moghetti.

This means that affected individuals have well-developed breasts and a complete lack or extremely reduced presence of hair, including underarm and pubic hair. Menstruation is also completely absent because there is no uterus, and there are testes, not visible because they are considered in the abdomen.

“There are syndromes that are currently considered congenital but not genetic, of which a genetic origin will probably be identified in the future,” said Dr. Lala.

Some variations in sexual development can be diagnosed prenatally, such as an alteration of the number of sex chromosomes or a discordance between the morphologic characteristics highlighted by ultrasound and the genotype detected by amniocentesis. Some variations are evident at birth because of atypical anatomical characteristics. Others are diagnosed during puberty or later in adulthood, in the presence of infertility. The Italian National Institute of Health details these variations on its website, describing the characteristics that determine diagnosis and treatment.
 

Pathologies or Variations?

Some anomalies in sexual development negatively affect the patient’s physical health. One example is congenital adrenal hyperplasia. “It results from an inherited defect of the adrenal glands, which reduces cortisol production while increasing testosterone production,” said Dr. Lala. “In addition to the appearance of male characteristics in females, in more severe forms, it carries the risk of collapse and shock and requires pharmacological treatment.” It is undoubtedly a pathology.

Other variations in sexual characteristics do not affect the patient’s physical health negatively. They may, however, have a psychologic effect, sometimes a significant one, because of the lack of social acceptance of a person who cannot be classified within the binary classification of sexes.

“Conditions in which mixed male and female aspects are clearly evident have been and are still pathologized by the family, the treating physician, and society,” said Dr. Lala. “In the late 1970s, when a child was born with intersexual anatomical characteristics, it was common practice to surgically intervene, making them female, because it was technically easier.”

Over the years, patients who, as they grew up, were dissatisfied with the solution adopted at birth began to make their voices heard, Dr. Lala added. Scientific societies and international organizations have spoken out against subjecting intersexual newborns to surgical interventions that are not medically necessary. “Nowadays, decisions are made on a case-by-case basis, taking into account the families’ wishes. Interventions are justified with medical reasons, which are often very nuanced,” Dr. Lala concluded.
 

Implications for Sports

Traditionally, athletes participating in competitions in certain sports have been divided into male and female categories to ensure a certain equity and uniformity in performance. Over the years, the emergence of new information about sexual development has made it necessary to update the criteria used in this division.

The main factor responsible for the performance diversity between males and females is the action of testosterone on the male and female organism. “Testosterone has important effects on muscle mass and enhances training results,” said Dr. Moghetti. “As a demonstration of this fact, before puberty, the best performances in athletics or swimming by males and females are similar, then males gain a significant advantage of around 10%-20%.”

A few years ago, the World Athletics Federation conducted widespread screening of athletes participating in its world championships. “It identified a small group of individuals with potentially abnormal testosterone levels for the female sex,” said Dr. Moghetti. “Some were found to be doping, others had genetic defects, and for some, an interpretation was not even possible.”

Some of the individuals had a male genotype but a defect in 5-alpha-reductase, an enzyme essential for the formation of male genitals and hair growth. An athlete with these characteristics, assigned female sex at birth, has a male level of testosterone that stimulates the accumulation of muscle mass, Dr. Moghetti explained. Therefore, the individual has a considerable advantage in performances influenced by this hormone.

“In the end, the Federation decided to set limits on the testosterone levels of athletes participating in certain types of races, especially those in middle distance, that appeared to be more sensitive to differences in hormone levels,” said Dr. Moghetti. “The limitation does not apply to athletes with Morris syndrome, ie, with a male genotype and complete resistance to testosterone, for whom the high level of this hormone does not provide any advantage.” Given the complexity of the problem, he hopes for a case-by-case policy that considers the needs of patients with genetic alterations and those of athletes who have to compete with them.
 

Not the First Time

A recent incident underscored the difficulty of regulating such complex issues. The World Athletics Federation excluded South African middle-distance runner Caster Semenya from competitions years ago because of excessively high testosterone levels.

“The Federation’s regulations recommend that athletes in these cases reduce hormone levels to values below the threshold of 5 nmol/L of blood for a period of at least 6 months before the race by using hormonal contraceptives. The use of such drugs does not pose a health risk, as they are substances normally taken by women for contraception purposes,” said Amelia Filippelli, a pharmacologist at the University of Salerno in Italy. The South African middle-distance runner refused the drug and appealed to the Court of Arbitration for Sport and later to the Swiss Federal Court. Both rejected her appeal. Finally, Ms. Semenya appealed to the European Court of Human Rights, which in 2023 recognized a violation of her rights but does not have the authority to order a change in the Federation’s regulations.

Beyond the ideologic positions of nonexperts, therefore, the issue is still the subject of debate in the scientific community, which is evaluating not only its medical aspects but also its ethical implications.

Since the COVID-19 pandemic, alcoholic hand sanitizers have become widely accessible nationwide. They can pose a problem, especially for emergency departments, when alcohol-dependent patients start drinking them. One example that demonstrates the challenge of diagnosing alcohol abuse is the medical history of a young man, as reported by Mahmoud El Hussein, MD, and colleagues from Hôpital Lariboisière in Paris, France.

Presentation and History

A 26-year-old man presented with severe abdominal pain at the emergency department. Upon arrival, he was hemodynamically stable but nervous and verbally aggressive at times. The patient reported no relevant preexisting conditions and was not taking any medications.

Findings

Upon initial physical examination, the patient had a soft, diffusely tender abdomen; tachycardia; and notably poor hygiene. The patient was afebrile. An ECG confirmed the tachycardia but showed no signs of ischemia. Blood work, except for slightly elevated liver values, did not reveal any abnormalities, particularly ruling out bleeding or kidney disease.

A urease rapid test to rule out kidney stones also showed no pathologic findings. In consultation with the surgical department, a CT scan of the abdomen was performed to rule out organ perforation, volvulus, or mesenteric ischemia. Only signs of fatty liver were found.
 

A Neighbor’s Tip

During all examinations, the patient’s abdomen was repeatedly palpated to promptly detect signs of an acute abdomen. However, there was never any defense tension at any point.

Intravenous analgesics and proton pump inhibitors (ie, paracetamol, phloroglucin, and pantoprazole) did not relieve the patient’s symptoms. Morphine was administered intravenously for sedation.

Only after a frustrating diagnostic process did a neighbor of the patient inform a nurse that he suspected the patient of stealing and consuming hand sanitizer. With the patient’s consent, a blood alcohol test was performed, revealing a blood alcohol concentration of 0.2% (2 g/L). A urine test, also conducted with the patient’s consent, tested positive for tetrahydrocannabinol. Additional tests showed the following results:

• Venous pH: 7.29 (normal, 7.32-7.38)
• Anion gap (mEq/L): 14 (normal, 3-9)
• Ketone bodies (mmol/L): 0.2 (normal, < 0.6)
• Calculated serum osmolality (mOsm/kg): 292 (normal, 285-295)
• Measured serum osmolality (mOsm/kg): 320 (normal, 285-295)
• Osmolality gap (mOsm/kg): 2 (normal, < 10)

The patient was informed of the test results and confessed to feigning abdominal pain. He was dependent on alcohol and experiencing withdrawal symptoms. The patient had stolen seven 475-mL bottles of hand sanitizer and consumed one and a half in the past 4-6 hours. According to the authors, the sanitizer consisted of 80% ethanol, 1.45% glycerol, and 0.13% hydrogen peroxide.
 

Discussion

In Germany, alcohol consumption results in approximately €57 billion in direct economic costs annually, according to data from the Federal Ministry of Health. In 2021, about 7.9 million people aged 18-64 years consumed alcohol in a risky manner (approximately 9.6% of the German population). About 9 million people (approximately 11%) were classified as alcoholics.

The authors of the case report pointed out that those in the advanced stages of alcohol addiction often consume any alcoholic liquid they can access. This includes alcoholic hand sanitizers commonly used in hospitals. Therefore, staff in emergency departments, where potential abusers encounter a wide range of potential abuse items, should exercise caution.

Although hand sanitizers are mainly composed of ethanol, they may also contain isopropanol, methanol, or acetone. Methanol poisoning can cause abdominal pain, visual disturbances, central nervous system damage, and death. Other alcohols such as ethylene glycol, commonly found in antifreeze, can distort blood values (lactate) and complicate a correct diagnosis.

Physicians working in emergency departments should proceed with caution when suspecting alcohol abuse. Questioning the patient’s environment and determining additional laboratory parameters (such as osmolality gap in the case report) can help unmask substance abuse if it is in doubt.

• Calculated serum osmolality (mOsm/kg): 292 (normal, 285-295)
• Measured serum osmolality (mOsm/kg): 320 (normal, 285-295)
• Osmolality gap (mOsm/kg): 2 (normal, < 10)

The patient was informed of the test results and confessed to feigning abdominal pain. He was dependent on alcohol and experiencing withdrawal symptoms. The patient had stolen seven 475-mL bottles of hand sanitizer and consumed one and a half in the past 4-6 hours. According to the authors, the sanitizer consisted of 80% ethanol, 1.45% glycerol, and 0.13% hydrogen peroxide.
 

Discussion

In Germany, alcohol consumption results in approximately €57 billion in direct economic costs annually, according to data from the Federal Ministry of Health. In 2021, about 7.9 million people aged 18-64 years consumed alcohol in a risky manner (approximately 9.6% of the German population). About 9 million people (approximately 11%) were classified as alcoholics.

The authors of the case report pointed out that those in the advanced stages of alcohol addiction often consume any alcoholic liquid they can access. This includes alcoholic hand sanitizers commonly used in hospitals. Therefore, staff in emergency departments, where potential abusers encounter a wide range of potential abuse items, should exercise caution.

Although hand sanitizers are mainly composed of ethanol, they may also contain isopropanol, methanol, or acetone. Methanol poisoning can cause abdominal pain, visual disturbances, central nervous system damage, and death. Other alcohols such as ethylene glycol, commonly found in antifreeze, can distort blood values (lactate) and complicate a correct diagnosis.

Physicians working in emergency departments should proceed with caution when suspecting alcohol abuse. Questioning the patient’s environment and determining additional laboratory parameters (such as osmolality gap in the case report) can help unmask substance abuse if it is in doubt.

Since the COVID-19 pandemic, alcoholic hand sanitizers have become widely accessible nationwide. They can pose a problem, especially for emergency departments, when alcohol-dependent patients start drinking them. One example that demonstrates the challenge of diagnosing alcohol abuse is the medical history of a young man, as reported by Mahmoud El Hussein, MD, and colleagues from Hôpital Lariboisière in Paris, France.

Presentation and History

A 26-year-old man presented with severe abdominal pain at the emergency department. Upon arrival, he was hemodynamically stable but nervous and verbally aggressive at times. The patient reported no relevant preexisting conditions and was not taking any medications.

Findings

Upon initial physical examination, the patient had a soft, diffusely tender abdomen; tachycardia; and notably poor hygiene. The patient was afebrile. An ECG confirmed the tachycardia but showed no signs of ischemia. Blood work, except for slightly elevated liver values, did not reveal any abnormalities, particularly ruling out bleeding or kidney disease.

A urease rapid test to rule out kidney stones also showed no pathologic findings. In consultation with the surgical department, a CT scan of the abdomen was performed to rule out organ perforation, volvulus, or mesenteric ischemia. Only signs of fatty liver were found.
 

A Neighbor’s Tip

During all examinations, the patient’s abdomen was repeatedly palpated to promptly detect signs of an acute abdomen. However, there was never any defense tension at any point.

Intravenous analgesics and proton pump inhibitors (ie, paracetamol, phloroglucin, and pantoprazole) did not relieve the patient’s symptoms. Morphine was administered intravenously for sedation.

Only after a frustrating diagnostic process did a neighbor of the patient inform a nurse that he suspected the patient of stealing and consuming hand sanitizer. With the patient’s consent, a blood alcohol test was performed, revealing a blood alcohol concentration of 0.2% (2 g/L). A urine test, also conducted with the patient’s consent, tested positive for tetrahydrocannabinol. Additional tests showed the following results:

• Venous pH: 7.29 (normal, 7.32-7.38)
• Anion gap (mEq/L): 14 (normal, 3-9)
• Ketone bodies (mmol/L): 0.2 (normal, < 0.6)
• Calculated serum osmolality (mOsm/kg): 292 (normal, 285-295)
• Measured serum osmolality (mOsm/kg): 320 (normal, 285-295)
• Osmolality gap (mOsm/kg): 2 (normal, < 10)

The patient was informed of the test results and confessed to feigning abdominal pain. He was dependent on alcohol and experiencing withdrawal symptoms. The patient had stolen seven 475-mL bottles of hand sanitizer and consumed one and a half in the past 4-6 hours. According to the authors, the sanitizer consisted of 80% ethanol, 1.45% glycerol, and 0.13% hydrogen peroxide.
