TOPLINE:

Oral intragastric expandable capsules taken twice daily before meals reduce body weight in adults with overweight or obesity compared with placebo, with mild gastrointestinal adverse events.

METHODOLOGY:

• Numerous anti-obesity pharmacotherapies have demonstrated effectiveness in reducing weight, but they may lead to side effects.
• This 24-week phase 3 randomized placebo-controlled study evaluated 2.24 g oral intragastric expandable capsules for weight loss in 280 adults (ages 18-60 years) with overweight or obesity (body mass index ≥ 24 kg/m2).
• One capsule, taken before lunch and dinner with water, expands to fill about one quarter of average stomach volume and then passes through the body, similar to the US Food and Drug Administration–cleared device Plenity.
• Primary endpoints were the percentage change in body weight from baseline and the weight loss response rate (weight loss of at least 5% of baseline body weight) at week 24.
• Researchers analyzed efficacy outcomes in two ways: Intention to treat (a full analysis based on groups to which they were randomly assigned) and per protocol (based on data from participants who follow the protocol).

TAKEAWAY:

• At 24 weeks, the change in mean body weight was higher with intragastric expandable capsules than with placebo using the per protocol set (estimated treatment difference [ETD], −3.6%; P < .001), with similar results using the full analysis set.
• The weight loss response rate at 24 weeks was higher with intragastric expandable capsules than with placebo using the per protocol set (ETD, 29.6%; P < .001), with similar results using the full analysis set.
• Reduction in fasting insulin levels was higher with intragastric expandable capsules than with placebo (P = .008), while improvements in the lipid profile, fasting plasma glucose levels, and heart rate were similar between the groups.
• Gastrointestinal disorders were reported in 25.0% of participants in the intragastric expandable capsule group compared with 21.9% in the placebo group, with most being transient and mild in severity.

IN PRACTICE:

“As a mild and safe anti-obesity medication, intragastric expandable capsules provide a new therapeutic choice for individuals with overweight or obesity, helping them to enhance and maintain the effect of diet restriction,” wrote the authors.

Difei Lu, MD, Department of Endocrinology, Peking University First Hospital, Beijing, China, led the study, which was published online in Diabetes, Obesity and Metabolism.

LIMITATIONS:

The study included individuals who were overweight or obese, who might have been more willing to lose weight than the general population. Moreover, only 3.25% of the participants had type 2 diabetes, and participants were relatively young. This may have reduced the potential to discover metabolic or cardiovascular improvement by the product.

TOPLINE:

Persistent hypertriglyceridemia is linked to an increased risk for type 2 diabetes (T2D) in young adults, independent of lifestyle factors.

METHODOLOGY:

• This prospective study analyzed the data of 1,840,251 individuals aged 20-39 years from the South Korean National Health Insurance Service database (mean age 34 years, 71% male).
• The individuals had undergone four consecutive annual health checkups between 2009 and 2012 and had no history of T2D.
• The individuals were sorted into five groups indicating the number of hypertriglyceridemia diagnoses over four consecutive years: 0, 1, 2, 3, and 4, defined as serum fasting triglyceride levels of 150 mg/dL or higher.
• Data on lifestyle-related risk factors, such as smoking status and heavy alcohol consumption, were collected through self-reported questionnaires.
• The primary outcome was newly diagnosed cases of T2D. Over a mean follow-up of 6.53 years, a total of 40,286 individuals developed T2D.

TAKEAWAY:

• The cumulative incidence of T2D increased with an increase in exposure scores for hypertriglyceridemia (log-rank test, P < .001), independent of lifestyle-related factors.
• The incidence rate per 1000 person-years was 1.25 for participants with an exposure score of 0 and 11.55 for those with a score of 4.
• For individuals with exposure scores of 1, 2, 3, and 4, the adjusted hazard ratios for incident diabetes were 1.674 (95% CI, 1.619-1.732), 2.192 (2.117-2.269), 2.637 (2.548-2.73), and 3.715 (3.6-3.834), respectively, vs those with an exposure score of 0.
• Exploratory subgroup analyses suggested the risk for T2D in persistent hypertriglyceridemia were more pronounced among people in their 20s than in their 30s and in women.

IN PRACTICE:

“Identification of individuals at higher risk based on triglyceride levels and management strategies for persistent hypertriglyceridemia in young adults could potentially reduce the burden of young-onset type 2 diabetes and enhance long-term health outcomes,” the authors wrote.

SOURCE:

The study, led by Min-Kyung Lee, Division of Endocrinology and Metabolism, Department of Internal Medicine, Myongji Hospital, Hanyang University College of Medicine, Seoul, Republic of Korea, was published online in Diabetes Research and Clinical Practice.

LIMITATIONS:

The scoring system based on fasting triglyceride levels of ≥ 150 mg/dL may have limitations, as the cumulative incidence of T2D also varied significantly for mean triglyceride levels. Moreover, relying on a single annual health checkup for hypertriglyceridemia diagnosis might not capture short-term fluctuations. Despite sufficient cases and a high follow-up rate, the study might have underestimated the incidence of T2D.

DISCLOSURES:

This work was supported by the National Research Foundation of Korea grant funded by the Korean Government and the faculty grant of Myongji Hospital. The authors declared no conflicts of interest.

“New antibiotics discovered using AI!”

That’s how headlines read in December 2023, when MIT researchers announced a new class of antibiotics that could wipe out the drug-resistant superbug methicillin-resistant Staphylococcus aureus (MRSA) in mice.

Powered by deep learning, the study was a significant breakthrough. Few new antibiotics have come out since the 1960s, and this one in particular could be crucial in fighting tough-to-treat MRSA, which kills more than 10,000 people annually in the United States.

But as remarkable as the antibiotic discovery was, it may not be the most impactful part of this study.

The researchers used a method known as explainable artificial intelligence (AI), which unveils the AI’s reasoning process, sometimes known as the black box because it’s hidden from the user. Their work in this emerging field could be pivotal in advancing new drug design.

“Of course, we view the antibiotic-discovery angle to be very important,” said Felix Wong, PhD, a colead author of the study and postdoctoral fellow at the Broad Institute of MIT and Harvard, Cambridge, Massachusetts. “But I think equally important, or maybe even more important, is really our method of opening up the black box.”

The black box is generally thought of as impenetrable in complex machine learning models, and that poses a challenge in the drug discovery realm.

“A major bottleneck in AI-ML-driven drug discovery is that nobody knows what the heck is going on,” said Dr. Wong. Models have such powerful architectures that their decision-making is mysterious.

Researchers input data, such as patient features, and the model says what drugs might be effective. But researchers have no idea how the model arrived at its predictions — until now.

What the Researchers Did

Dr. Wong and his colleagues first mined 39,000 compounds for antibiotic activity against MRSA. They fed information about the compounds’ chemical structures and antibiotic activity into their machine learning model. With this, they “trained” the model to predict whether a compound is antibacterial.

Next, they used additional deep learning to narrow the field, ruling out compounds toxic to humans. Then, deploying their various models at once, they screened 12 million commercially available compounds. Five classes emerged as likely MRSA fighters. Further testing of 280 compounds from the five classes produced the final results: Two compounds from the same class. Both reduced MRSA infection in mouse models.

How did the computer flag these compounds? The researchers sought to answer that question by figuring out which chemical structures the model had been looking for.

A chemical structure can be “pruned” — that is, scientists can remove certain atoms and bonds to reveal an underlying substructure. The MIT researchers used the Monte Carlo Tree Search, a commonly used algorithm in machine learning, to select which atoms and bonds to edit out. Then they fed the pruned substructures into their model to find out which was likely responsible for the antibacterial activity.

“The main idea is we can pinpoint which substructure of a chemical structure is causative instead of just correlated with high antibiotic activity,” Dr. Wong said.

This could fuel new “design-driven” or generative AI approaches where these substructures become “starting points to design entirely unseen, unprecedented antibiotics,” Dr. Wong said. “That’s one of the key efforts that we’ve been working on since the publication of this paper.”

More broadly, their method could lead to discoveries in drug classes beyond antibiotics, such as antivirals and anticancer drugs, according to Dr. Wong.

“This is the first major study that I’ve seen seeking to incorporate explainability into deep learning models in the context of antibiotics,” said César de la Fuente, PhD, an assistant professor at the University of Pennsylvania, Philadelphia, Pennsylvania, whose lab has been engaged in AI for antibiotic discovery for the past 5 years.

“It’s kind of like going into the black box with a magnifying lens and figuring out what is actually happening in there,” Dr. de la Fuente said. “And that will open up possibilities for leveraging those different steps to make better drugs.”

How Explainable AI Could Revolutionize Medicine

In studies, explainable AI is showing its potential for informing clinical decisions as well — flagging high-risk patients and letting doctors know why that calculation was made. University of Washington researchers have used the technology to predict whether a patient will have hypoxemia during surgery, revealing which features contributed to the prediction, such as blood pressure or body mass index. Another study used explainable AI to help emergency medical services providers and emergency room clinicians optimize time — for example, by identifying trauma patients at high risk for acute traumatic coagulopathy more quickly.

A crucial benefit of explainable AI is its ability to audit machine learning models for mistakes, said Su-In Lee, PhD, a computer scientist who led the UW research.

For example, a surge of research during the pandemic suggested that AI models could predict COVID-19 infection based on chest x-rays. Dr. Lee’s research used explainable AI to show that many of the studies were not as accurate as they claimed. Her lab revealed that many models› decisions were based not on pathologies but rather on other aspects such as laterality markers in the corners of x-rays or medical devices worn by patients (like pacemakers). She applied the same model auditing technique to AI-powered dermatology devices, digging into the flawed reasoning in their melanoma predictions. 

Explainable AI is beginning to affect drug development too. A 2023 study led by Dr. Lee used it to explain how to select complementary drugs for acute myeloid leukemia patients based on the differentiation levels of cancer cells. And in two other studies aimed at identifying Alzheimer’s therapeutic targets, “explainable AI played a key role in terms of identifying the driver pathway,” she said.

Currently, the US Food and Drug Administration (FDA) approval doesn’t require an understanding of a drug’s mechanism of action. But the issue is being raised more often, including at December’s Health Regulatory Policy Conference at MIT’s Jameel Clinic. And just over a year ago, Dr. Lee predicted that the FDA approval process would come to incorporate explainable AI analysis.

“I didn’t hesitate,” Dr. Lee said, regarding her prediction. “We didn’t see this in 2023, so I won’t assert that I was right, but I can confidently say that we are progressing in that direction.”

What’s Next?

The MIT study is part of the Antibiotics-AI project, a 7-year effort to leverage AI to find new antibiotics. Phare Bio, a nonprofit started by MIT professor James Collins, PhD, and others, will do clinical testing on the antibiotic candidates.

Even with the AI’s assistance, there’s still a long way to go before clinical approval.

But knowing which elements contribute to a candidate’s effectiveness against MRSA could help the researchers formulate scientific hypotheses and design better validation, Dr. Lee noted. In other words, because they used explainable AI, they could be better positioned for clinical trial success.

Further testing of 280 compounds from the five classes produced the final results: Two compounds from the same class. Both reduced MRSA infection in mouse models.

How did the computer flag these compounds? The researchers sought to answer that question by figuring out which chemical structures the model had been looking for.

A chemical structure can be “pruned” — that is, scientists can remove certain atoms and bonds to reveal an underlying substructure. The MIT researchers used the Monte Carlo Tree Search, a commonly used algorithm in machine learning, to select which atoms and bonds to edit out. Then they fed the pruned substructures into their model to find out which was likely responsible for the antibacterial activity.

“The main idea is we can pinpoint which substructure of a chemical structure is causative instead of just correlated with high antibiotic activity,” Dr. Wong said.

This could fuel new “design-driven” or generative AI approaches where these substructures become “starting points to design entirely unseen, unprecedented antibiotics,” Dr. Wong said. “That’s one of the key efforts that we’ve been working on since the publication of this paper.”

More broadly, their method could lead to discoveries in drug classes beyond antibiotics, such as antivirals and anticancer drugs, according to Dr. Wong.

“This is the first major study that I’ve seen seeking to incorporate explainability into deep learning models in the context of antibiotics,” said César de la Fuente, PhD, an assistant professor at the University of Pennsylvania, Philadelphia, Pennsylvania, whose lab has been engaged in AI for antibiotic discovery for the past 5 years.

“It’s kind of like going into the black box with a magnifying lens and figuring out what is actually happening in there,” Dr. de la Fuente said. “And that will open up possibilities for leveraging those different steps to make better drugs.”

How Explainable AI Could Revolutionize Medicine

In studies, explainable AI is showing its potential for informing clinical decisions as well — flagging high-risk patients and letting doctors know why that calculation was made. University of Washington researchers have used the technology to predict whether a patient will have hypoxemia during surgery, revealing which features contributed to the prediction, such as blood pressure or body mass index. Another study used explainable AI to help emergency medical services providers and emergency room clinicians optimize time — for example, by identifying trauma patients at high risk for acute traumatic coagulopathy more quickly.

A crucial benefit of explainable AI is its ability to audit machine learning models for mistakes, said Su-In Lee, PhD, a computer scientist who led the UW research.

For example, a surge of research during the pandemic suggested that AI models could predict COVID-19 infection based on chest x-rays. Dr. Lee’s research used explainable AI to show that many of the studies were not as accurate as they claimed. Her lab revealed that many models› decisions were based not on pathologies but rather on other aspects such as laterality markers in the corners of x-rays or medical devices worn by patients (like pacemakers). She applied the same model auditing technique to AI-powered dermatology devices, digging into the flawed reasoning in their melanoma predictions. 

Explainable AI is beginning to affect drug development too. A 2023 study led by Dr. Lee used it to explain how to select complementary drugs for acute myeloid leukemia patients based on the differentiation levels of cancer cells. And in two other studies aimed at identifying Alzheimer’s therapeutic targets, “explainable AI played a key role in terms of identifying the driver pathway,” she said.

Currently, the US Food and Drug Administration (FDA) approval doesn’t require an understanding of a drug’s mechanism of action. But the issue is being raised more often, including at December’s Health Regulatory Policy Conference at MIT’s Jameel Clinic. And just over a year ago, Dr. Lee predicted that the FDA approval process would come to incorporate explainable AI analysis.

“I didn’t hesitate,” Dr. Lee said, regarding her prediction. “We didn’t see this in 2023, so I won’t assert that I was right, but I can confidently say that we are progressing in that direction.”

What’s Next?

The MIT study is part of the Antibiotics-AI project, a 7-year effort to leverage AI to find new antibiotics. Phare Bio, a nonprofit started by MIT professor James Collins, PhD, and others, will do clinical testing on the antibiotic candidates.

Even with the AI’s assistance, there’s still a long way to go before clinical approval.

But knowing which elements contribute to a candidate’s effectiveness against MRSA could help the researchers formulate scientific hypotheses and design better validation, Dr. Lee noted. In other words, because they used explainable AI, they could be better positioned for clinical trial success.

TOPLINE:

Belantamab mafodotin plus a combination of bortezomib and dexamethasone improved median progression-free survival (PFS) by 23 months in patients with relapsed or refractory multiple myeloma, compared with daratumumab alongside the same combination.
 

METHODOLOGY:

• Belantamab mafodotin, a first-in-class anti-BCMA monoclonal antibody conjugate, was approved in the US in 2020 for adult patients with relapsed or refractory multiple myeloma who had received at least 4 prior therapies. However, in February 2023, the FDA withdrew this approval, following disappointing findings from a large confirmatory trial, called DREAMM-3. Although the agent is still being investigated to treat relapsed or refractory multiple myeloma, the current FDA label says the agent is only available in the US through a restricted program.
• Patients with multiple myeloma who relapse often become refractory to frontline triplet or quadruplet regimens and need effective second-line options.
• In the current phase 3 DREAMM-7 study, the researchers evaluated triplet therapy with belantamab mafodotin vs daratumumab as a second-line or later treatment option in patients with relapsed or refractory multiple myeloma.
• In this multicenter, open-label, randomized, phase 3 trial, 494 patients with relapsed/refractory multiple myeloma who previously received at least one prior line of therapy received bortezomib plus dexamethasone with either belantamab mafodotin or daratumumab.
• The primary outcome was PFS; secondary endpoints were overall survival, duration of response, and overall response rate.

TAKEAWAY:

• At a median follow-up of 28.2 months, patients who received belantamab mafodotin demonstrated significantly longer median PFS than those who received daratumumab (36.6 vs 13.4 months; hazard ratio [HR], 0.41). The improvement was evident in all prespecified groups, including patients refractory to lenalidomide (HR, 0.37) and those with a high risk for cytogenetic abnormalities (HR, 0.36).
• The early overall survival trend favored belantamab mafodotin — with 84% of patients alive at 18 months vs 73% in the daratumumab group — but overall survival follow-up is ongoing.
• The overall response rate was 83% in the belantamab mafodotin group vs 71% in the daratumumab group. Complete response rates were also higher in the belantamab mafodotin: 34.6% vs 17.1%. Median duration of response was twice as long in the belantamab mafodotin group (36 vs 18 months).
• Grade 3 or higher non-ocular adverse events in belantamab mafodotin vs daratumumab group included thrombocytopenia (55% vs 35%), infections and infestations (31% vs 20%), neutropenia (12% vs 6%), pneumonia (12% vs 4%), and anemia (8% vs 10%). Grade 3 or higher ocular adverse events were reported in 34% of patients treated with belantamab mafodotin, but ocular toxicities reversed in most patients.

IN PRACTICE:

Based on favorable PFS and manageable safety profile, belantamab mafodotin in combination with bortezomib plus dexamethasone has potential to become a new standard of care in the second line or later among patients with relapsed or refractory multiple myeloma, the author concluded.

SOURCE:

This study, led by Maria-Victoria Mateos, MD, PhD, from University Hospital of Salamanca, Salamanca, Spain, was presented at ASCO Plenary Series: February 2024 Session and published in the Journal of Clinical Oncology.

LIMITATIONS:

Open-label design was a limitation of this study. Follow-up for overall survival was ongoing.

DISCLOSURES:

Picture your marriage proposal fantasy. Do you see a beautiful beach at sunset? The place where you first met your partner? Maybe a dream vacation — Paris, anyone? And perhaps most popular of all ... the ER?

Why not? For some couples who share medical careers, the hospital is home, and they turn the moment into something just as romantic as any Eiffel Tower backdrop. (And admittedly, sometimes they don’t.)

Since we’re approaching Valentine’s Day— often the #1 day of the year for engagements — lovestruck healthcare professionals take note. There are good ways to do it and, well, ill-advised ways. We spoke with three couples whose medical-themed proposals ended in the word “yes!” 

Heaven on the Helipad

When emergency medicine physician Anna Darby, MD, heard a trauma patient was arriving and urgently needed to be intubated, she raced up to the rooftop helipad. As soon as the elevator doors opened, she was met with quite a different scene than expected. There were rose petals ... lots and lots of rose petals.

With her best friends and colleagues lining a red carpet, the roof had been turned into a scene from The Bachelor. Each person gave her a rose. A friend even touched up her makeup and handed over her favorite hoop earrings, transforming her from busy doctor to soon-to-be fiancée. Her boyfriend, cardiologist Merije Chukumerije, MD, stood waiting. You can guess what happened next.

Dr. Chukumerije later wrote in an Instagram post, “We met at this hospital. So, it was only right that I bring her to its highest place as we’ve reached the peak of our union.” The couple actually met in the hospital cafeteria “like all the clichés,” Dr. Darby jokes. For them, the helipad experience was just as Insta-worthy as any braggable, grandiose proposal at a fancy restaurant or on a mountaintop.

“Seeing that scene was totally not what I expected,” Dr. Darby says. “I can’t even describe it. It’s like the second biggest hormonal shift, [second only to] having a baby.” She and Dr. Chukumerije now have two babies of their own, aged 2 months and 2 years old.

Good Morning, Doctor

It was February 2021, the height of the pandemic, and Raaga Vemula, MD, now in her palliative care/hospice care fellowship, was “selected” for a local news interview on COVID-19. Except the interview was really with Good Morning America. And the topic was really a proposal. 

Dr. Vemula met Steven Bean, MD, now doing a sleep medicine fellowship, in 2015. “I first saw her, and thought she was one of the prettiest women I’d ever seen. ... We ended up being in the same study group,” he says. “Let’s be honest, I applied to every med school she applied to.” 

Six years later, Dr. Bean connected with GMA through The Knot, a wedding planning website and registry. The made-up interview request for Dr. Vemula came from the residency program director, who was in on the surprise. Dr. Vemula’s family also knew what was up when she called with the “news.” 

The live broadcast took place at the hospital. Dr. Bean had an earpiece for the producers to give him directions. But “I was so nervous, I walked out immediately,” he says. He ended up standing behind Dr. Vemula. The mistake worked well for viewers though, building anticipation while she answered a COVID-19 question. “We got everybody excited,” says Dr. Bean. “So, when they said ’Raaga, turn around’ it worked out perfectly. She was confused as hell.”

Luckily, Dr. Vemula loves a good surprise. “He knows me very well,” she says. 

For her, the proposal was even more meaningful given their background together. “Medicine means so much to both of us and was such a big part of our lives,” she says. “That’s what shaped us to do this. ... I think in our hearts it was meant to be this way.” 

Who Says Masks Don’t Work?

Masks conjure up feelings for anyone living through the pandemic, especially medical personnel. But for Rhett Franklin and wife Lauren Gray, they will always symbolize of one of the biggest days of their lives.

Mr. Franklin worked in registration, often following Ms. Gray, an emergency room nurse, around with a wheeled computer station to gather patient information (what’s known as a “creeper,” which isn’t as creepy as it sounds). Eventually, she offered to grab a coffee with him, and when he suggested another coffee, she said it was time for him to buy her a drink. 

Mr. Franklin, now a manager of business operations for nursing administration, originally planned to propose to Ms. Gray on a trip to England. But the pandemic prevented their vacation with its potential castle backdrop. 

Mr. Franklin often picked up shifts making masks for frontline workers, and an alternate proposal idea started brewing. He schemed to have two very special masks made. “Mine was a black tuxedo that said, ‘Will you marry me?’ and hers resembled a white dress that said, ‘I said yes!’ ” Mr. Franklin says. 

But a text almost ruined the surprise. When Mr. Franklin messaged family members about his proposal plan the day before, one relative responded in a group chat that included Ms. Gray. This was when the busy ER came to the rescue — no time to read texts. Family members also started calling Ms. Gray on the hospital’s phoneline as a distraction. Unfazed, Mr. Franklin simply moved up the proposal to that night. 

At their favorite dog beach, as the sunset gleamed on the water, Mr. Franklin pulled his mask out and took a knee. He can’t recall what he said behind that mask. “It was kind of one of those blackout moments.” But Ms. Gray remembers for him — “You said ‘Let’s do this.’ ”

Warning Label

Everyone has different tastes. Some healthcare professionals have taken the medical theme further than these couples — maybe too far. A few have even faked life-threatening emergencies, showing up in the ER on a gurney with a made-up peanut allergy reaction or a severe injury and then pulling out a ring.

But who’s to judge? For some, thinking your partner is “dying” and then learning you’ve been tricked might not conjure up the warmest feelings. For others, apparently, it’s a virtual bouquet of roses. 

A Few Proposal Pointers

If you’re planning to pop the question, this group says, “go for the medical setting!” But according to them, there are other must-haves to get that “yes” and the lifetime of wedded bliss, of course:

• Make it a hospital-wide morale-booster. “Everyone loves surprises,” Dr. Bean maintains. So, why not bring your colleagues in on the conspiracy? “Involving coworkers will strengthen relationships with their work family by leaving lasting memories for everyone,” he says. “In a busy medical setting, it’s usually unexpected, so it makes it extra special.” 
• Have a backup plan. As healthcare professionals, you know that schedules get in the way of everything. So, practice that flexibility you will need as a marriage skill. When Mr. Franklin’s first two engagement locations fell though, he says, it was important to adapt and not panic when things went awry.
• Seize the moment. Think you can’t get engaged during residency? “Planning a proposal during intern year of residency is totally manageable,” Dr. Vemula says. “That way as residency progresses and you have more time, there is more time to focus on the wedding planning.” But she cautions that, “wedding planning during the intern year would be quite difficult.”

Six years later, Dr. Bean connected with GMA through The Knot, a wedding planning website and registry. The made-up interview request for Dr. Vemula came from the residency program director, who was in on the surprise. Dr. Vemula’s family also knew what was up when she called with the “news.” 

The live broadcast took place at the hospital. Dr. Bean had an earpiece for the producers to give him directions. But “I was so nervous, I walked out immediately,” he says. He ended up standing behind Dr. Vemula. The mistake worked well for viewers though, building anticipation while she answered a COVID-19 question. “We got everybody excited,” says Dr. Bean. “So, when they said ’Raaga, turn around’ it worked out perfectly. She was confused as hell.”

Luckily, Dr. Vemula loves a good surprise. “He knows me very well,” she says. 

For her, the proposal was even more meaningful given their background together. “Medicine means so much to both of us and was such a big part of our lives,” she says. “That’s what shaped us to do this. ... I think in our hearts it was meant to be this way.” 

Who Says Masks Don’t Work?

Masks conjure up feelings for anyone living through the pandemic, especially medical personnel. But for Rhett Franklin and wife Lauren Gray, they will always symbolize of one of the biggest days of their lives.

Mr. Franklin worked in registration, often following Ms. Gray, an emergency room nurse, around with a wheeled computer station to gather patient information (what’s known as a “creeper,” which isn’t as creepy as it sounds). Eventually, she offered to grab a coffee with him, and when he suggested another coffee, she said it was time for him to buy her a drink. 

Mr. Franklin, now a manager of business operations for nursing administration, originally planned to propose to Ms. Gray on a trip to England. But the pandemic prevented their vacation with its potential castle backdrop. 

Mr. Franklin often picked up shifts making masks for frontline workers, and an alternate proposal idea started brewing. He schemed to have two very special masks made. “Mine was a black tuxedo that said, ‘Will you marry me?’ and hers resembled a white dress that said, ‘I said yes!’ ” Mr. Franklin says. 

But a text almost ruined the surprise. When Mr. Franklin messaged family members about his proposal plan the day before, one relative responded in a group chat that included Ms. Gray. This was when the busy ER came to the rescue — no time to read texts. Family members also started calling Ms. Gray on the hospital’s phoneline as a distraction. Unfazed, Mr. Franklin simply moved up the proposal to that night. 

At their favorite dog beach, as the sunset gleamed on the water, Mr. Franklin pulled his mask out and took a knee. He can’t recall what he said behind that mask. “It was kind of one of those blackout moments.” But Ms. Gray remembers for him — “You said ‘Let’s do this.’ ”

Warning Label

Everyone has different tastes. Some healthcare professionals have taken the medical theme further than these couples — maybe too far. A few have even faked life-threatening emergencies, showing up in the ER on a gurney with a made-up peanut allergy reaction or a severe injury and then pulling out a ring.

But who’s to judge? For some, thinking your partner is “dying” and then learning you’ve been tricked might not conjure up the warmest feelings. For others, apparently, it’s a virtual bouquet of roses. 

A Few Proposal Pointers

If you’re planning to pop the question, this group says, “go for the medical setting!” But according to them, there are other must-haves to get that “yes” and the lifetime of wedded bliss, of course:

• Make it a hospital-wide morale-booster. “Everyone loves surprises,” Dr. Bean maintains. So, why not bring your colleagues in on the conspiracy? “Involving coworkers will strengthen relationships with their work family by leaving lasting memories for everyone,” he says. “In a busy medical setting, it’s usually unexpected, so it makes it extra special.” 
• Have a backup plan. As healthcare professionals, you know that schedules get in the way of everything. So, practice that flexibility you will need as a marriage skill. When Mr. Franklin’s first two engagement locations fell though, he says, it was important to adapt and not panic when things went awry.
• Seize the moment. Think you can’t get engaged during residency? “Planning a proposal during intern year of residency is totally manageable,” Dr. Vemula says. “That way as residency progresses and you have more time, there is more time to focus on the wedding planning.” But she cautions that, “wedding planning during the intern year would be quite difficult.”

TOPLINE:

A universal cardiovascular disease (CVD) prediction tool performs well in patients with and without atherosclerotic CVD (ASCVD), a new study showed, suggesting this model could facilitate transition from primary to secondary prevention by streamlining risk classification.

METHODOLOGY:

• Researchers used different models to evaluate whether established CVD predictors, including age, sex, race, diabetes, systolic blood pressure, or smoking, are associated with major adverse cardiovascular events (MACEs), including myocardial infarction (MI), stroke, and heart failure (HF), among 9138 patients, mean age 63.8 years, in the Atherosclerosis Risk in Communities (ARIC) study.
• Of these, 609 had ASCVD (history of MI, ischemic stroke, or symptomatic peripheral artery disease) and 8529 did not.
• They extended their exploration to other predictors available in clinical practice, including family history of premature ASCVD, high-sensitivity C-reactive protein, lipoprotein(a), triglycerides, and apolipoprotein B, as well as predictors of HF such as body mass index and heart rate and blood-based cardiac biomarkers.
• An external validation analysis included 5322 participants in the Multi-Ethnic Study of Atherosclerosis (MESA).
• Over a median follow-up of 18.9 years, 3209 ARIC participants (35%) developed MACE for an incidence rate per 1000 person-years of 21.3 for MACE, 12.6 for MI/stroke, and 13.8 for HF.

TAKEAWAY:

• Of all candidate predictors, 10 variables (including established predictors and cardiac biomarkers) were included in the universal prediction model, which demonstrated good calibration in both those with ASCVD (hazard ratio [HR] C-statistic, 0.692; 95% CI, 0.650-0.735) and without ASCVD (HR C-statistic, 0.748; 95% CI, 0.726-0.770).
• As anticipated, the risk for MACE was generally lower in those with no prior ASCVD, but the 5-year risk in the highest quintile of predicted risk in those without ASCVD was higher than that in the lowest two quintiles of the ASCVD group.
• The universal risk prediction model was validated in the MESA community–based cohort; over a median follow-up of 13.7 years, 12% of participants with and without prior ASCVD developed MACE for an incidence rate per 1000 person-years of 10.2 for MACE, 7.4 for MI/stroke, and 4.3 for HF.
• The results were generally similar when examining individual outcomes (MI/stroke and HF) and for both no ASCVD and ASCVD groups across demographic subgroups by age, sex, and race.

IN PRACTICE:

The findings “support the importance of established predictors for classifying long-term CVD risk in both primary and secondary prevention settings,” the authors wrote, adding an advantage to this risk prediction approach could be to help providers and patients “further personalize secondary prevention.”

In an accompanying editorial, Pier Sergio Saba, MD, PhD, Clinical and Interventional Cardiology, Sassari University Hospital, Sassari, Italy, and others said the universal risk assessment approach “is conceptually promising” but noted patients with ASCVD represented only 7% of the study population, and this population was relatively young, potentially limiting the applicability of this risk model in older individuals. Before the risk model can be used in clinical settings, results need to be validated and given incorporation of cardiac biomarkers, “careful cost-benefit analyses may also be needed,” the editorial writers added.

SOURCE:

The study was conducted by Yejin Mok, PHD, MPH, Department of Epidemiology, Johns Hopkins Bloomberg School of Public Health, Baltimore, and colleagues. It was published online on January 29, 2024, in the Journal of the American College of Cardiology (JACC).

LIMITATIONS:

The somewhat limited number of study participants with prior ASCVD precluded researchers from quantifying the prognostic impact of ASCVD subtypes (eg, history of MI vs stroke vs peripheral artery disease). The study didn’t have data on some predictors recognized in guidelines (eg, coronary artery calcium and left ventricular ejection fraction). The ARIC analysis included only Black and White participants, and although models were validated in MESA, which included Chinese and Hispanic adults, extrapolation of results to more racially/ethnically diverse populations should be done with care.

DISCLOSURES:

The ARIC study received funding from the National Heart, Lung, and Blood Institute (NHLBI), National Institutes of Health, and Department of Health and Human Services. The MESA study was supported by the NHLBI and National Center for Advancing Translational Sciences. The study authors and editorial writers had no relevant conflicts of interest.

Replacing regular salt with a salt substitute reduced the incidence of new hypertension compared with a usual salt group, without provoking hypotension, new data showed.

Among a group of older adults with normal blood pressure (BP), those who swapped table salt for a salt substitute — consisting of 62.5% sodium chloride, 25% potassium chloride, and 12.5% flavorings — were 40% less apt to develop hypertension over 2 years than were peers who continued with regular salt.

“From a public health perspective, our study results indicate that everyone in the whole population, either hypertensive or normotensive, can benefit from replacing regular salt with potassium-enriched salt substitute,” lead author Yangfeng Wu, MD, PhD, professor and executive associate director, Peking University Clinical Research Institute, Beijing, China, told this news organization.

“Thus, salt substitution should be considered and promoted as a whole-population strategy for prevention and control of hypertension and cardiovascular disease,” Dr. Wu said.

The study was published online on February 12 in the Journal of the American College of Cardiology.

“Considering the failing strategy to reduce the intake of salt worldwide, salt substitution is an attractive alternative. The food industry and authorities should prepare strategies for wide-scale implementation of salt substitutes,” Rik Olde Engberink, MD, PhD, with Amsterdam University Medical Center, wrote in a linked editorial.

Population Strategy for Hypertension Prevention

The DECIDE-Salt clinical trial was a cluster-randomized trial conducted in 48 residential elderly care facilities in China with 1612 participants (1230 men and 382 women) aged 55 years or older. The trial assessed the effect of two sodium reduction strategies in lowering BP — replacing salt with a salt substitute and progressive restriction of the salt supply.

In the original study, the salt substitute intervention lowered systolic/diastolic BP significantly by 7.1/1.9 mm Hg vs the usual salt group. The progressive restriction of salt had no impact on BP vs usual salt or salt substitute groups.

This post hoc analysis of DECIDE-Salt focused on 609 participants (mean age, 71 years; 74% men) who were normotensive at baseline (mean BP, 122/74 mm Hg), with 298 in the usual salt group and 313 in the salt substitute group.

Compared with the usual salt group, the salt substitute group had a lower incidence of hypertension over 2 years (adjusted hazard ratio [HR], 0.60; 95% CI, 0.39-0.92; P = .02), with no increase in episodes of hypotension (P = .76).

From baseline to 2 years, there was no change in mean systolic/diastolic BP in the salt substitution group, whereas the usual salt group experienced a significant increase in systolic/diastolic BP (mean, 7.0/2.1 mm Hg).

The post hoc results from DECIDE-Salt are in line with a previous study from Peru, which also investigated mostly normotensive participants and reported a 51% lower risk of developing hypertension in the salt substitute group, as reported previously by this news organization.

“Although the study involved only participants aged 55 years and above, the epidemic of hypertension and its relations with sodium and potassium intake are not limited to older adults. Thus, we believe the salt substitution should also be beneficial to younger adults,” Dr. Wu said.

Notable Analysis

Reached for comment, Ankur Shah, MD, Division of Kidney Disease and Hypertension, Warren Alpert Medical School of Brown University, Providence, Rhode Island, said the study is “notable due to the limited and conflicting reports on the effects of salt substitution in individuals with normal blood pressure.”

“There is a growing body of literature on the impact of salt substitution in controlling hypertension, but less is known about prevention,” Dr. Shah, who was not involved in the study, told this news organization.

“The study certainly has population-level implications, as the design of a cluster-randomized trial at the facility level makes for a clear path to implementation — sodium substitution in elderly care facilities. That said, this is also the greatest limitation — extrapolating to the general population may not be accurate,” Dr. Shah noted.

There is also a potential concern with salt substitutes in patients with kidney disease, who typically are advised to lower potassium intake.

“Supplementing potassium could result in hyperkalemia, which can be life-threatening if severe, and patients taking medications that interfere with the kidney’s ability to excrete potassium should be cautious as well,” Dr. Shah said.

This research was supported by a grant from the National Key Research and Development Program, Ministry of Science and Technology of China. China Salt General Company at Yulin provided the usual salt and salt substitute used in the study free of charge. Dr. Wu, Dr. Engberink, and Dr. Shah had no relevant conflicts of interest.

For active-duty service members, dermatologic conditions are among the most common presenting concerns, comprising 15% to 75% of wartime outpatient visits.¹ In general, there are unique considerations when caring for active-duty service members, including meeting designated active-duty retention and hierarchical standards.² We present a hypothetical case: An active-duty military patient presents to a new dermatologist for cosmetic enhancement of facial skin dyspigmentation. The patient will be leaving soon for deployment and will not be able to follow up for 9 months. How should the dermatologist treat a patient who cannot follow up for so long?

The therapeutic modalities offered can be impacted by forthcoming deployments³ that may result in delayed time to administer repeat treatments or follow-up. The patient may have high expectations for a single appointment for a condition that requires prolonged treatment courses. Because there often is no reliable mechanism for patients to obtain refills during deployment, any medications prescribed would need to be provided in advance for the entire deployment duration, which often is 6 to 9 months. Additionally, treatment monitoring or modifications are severely limited, especially in the context of treatment nonresponse or adverse reactions. Considering the unique limitations of this patient population, both military and civilian physicians are faced with a need to maximize beneficence and autonomy while balancing nonmaleficence and justice.

One possible option is to decline to treat until the patient can follow up after returning from deployment. However, denying a request for an active treatable indication for which the patient desires treatment compromises patient autonomy and beneficence. Further, treatment should be provided to patients equitably to maintain justice. Although there may be a role for discussing active monitoring with nonintervention with the patient, denying treatment can negatively impact their physical and mental health and may be harmful. However, the patient should know and fully understand the risks and benefits of nonintervention with limited follow-up, including suboptimal outcomes or adverse events.

Another possibility for the management of this case may be conducting a one-time laser or light-based therapy or a one-time superficial- to medium-depth chemical peel before the patient leaves on deployment. Often, a series of laser- or light-based treatments is required to maximize outcomes for dyspigmentation. Without follow-up and with possible deployment to an environment with high UV exposure, the patient may experience disease exacerbation or other adverse effects. Treatment of those adverse effects may be delayed, as further intervention is not possible during deployment. Lower initial laser settings may be safer but may not be highly effective initially. More rigorous treatment upon return from deployment may be considered. Similar to laser therapies, chemical peels usually require several treatments for optimal outcomes. Without follow-up and with potential deployment to remote environments, there is a risk for adverse events that outweighs the minimal benefit of a single treatment. Therefore, either intervention may violate the principle of nonmaleficence.

A more reasonable approach may be initiating topical therapy and following up via telemedicine evaluation. Topical therapy often is the least-invasive approach and carries a reduced risk for adverse effects. Triple-combination therapy with topical retinoids, hydroquinone, and topical steroids is a common first-line approach.⁴ Because this approach is patient dependent, therapy can be more easily modulated or halted in the context of undesired results. Additionally, if internet connectivity is available, an asynchronous telemedicine approach could be utilized during deployment to monitor and advise changes as necessary, provided the regulatory framework allows for it.⁵

Although there is no uniformly correct approach in a scenario of limited patient follow-up, the last solution may be most ethically favorable: to begin therapy with milder and safer therapies (topical) and defer higher-intensity regimens until the patient returns from deployment. This allows some treatment initiation to preserve justice, beneficence, and patient autonomy. Associated virtual follow-up via telemedicine also allows avoidance of nonmaleficence in this context.

For active-duty service members, dermatologic conditions are among the most common presenting concerns, comprising 15% to 75% of wartime outpatient visits.¹ In general, there are unique considerations when caring for active-duty service members, including meeting designated active-duty retention and hierarchical standards.² We present a hypothetical case: An active-duty military patient presents to a new dermatologist for cosmetic enhancement of facial skin dyspigmentation. The patient will be leaving soon for deployment and will not be able to follow up for 9 months. How should the dermatologist treat a patient who cannot follow up for so long?

The therapeutic modalities offered can be impacted by forthcoming deployments³ that may result in delayed time to administer repeat treatments or follow-up. The patient may have high expectations for a single appointment for a condition that requires prolonged treatment courses.

TOPLINE:

Spinal cord injury (SCI) is associated with a significantly greater risk for heart disease than that of the general non-SCI population, especially among those with severe disability, new observational data suggest.

METHODOLOGY:

• Researchers analyzed data from Korea’s National Health Insurance Service on 5083 patients with cervical, thoracic, or lumbar SCI (mean age, 58; 75% men) and 1:3 age- and sex-matched non-SCI controls.
• The study endpoint was new-onset myocardial infarction (MI), heart failure (HF), or atrial fibrillation (AF) during a mean follow-up of 4.3 years.
• Covariates included low income, living in an urban or rural area, alcohol consumption, smoking status, physical activity engagement, body mass index, and blood pressure; comorbidities included hypertension, type 2 diabetes, and dyslipidemia.

TAKEAWAY:

• A total of 169 MI events (7.3 per 1000 person-years), 426 HF events (18.8 per 1000 person-years), and 158 AF events (6.8 per 1000 person-years) occurred among SCI survivors.
• After adjustment, SCI survivors had a higher risk for MI (adjusted hazard ratio [aHR], 2.41), HF (aHR, 2.24), and AF (aHR, 1.84) than that of controls.
• Among SCI survivors with a disability, the risks increased with disability severity, and those with severe disability had the highest risks for MI (aHR, 3.74), HF (aHR, 3.96), and AF (aHR, 3.32).
• Cervical and lumbar SCI survivors had an increased risk for heart disease compared with controls regardless of disability, and the risk was slightly higher for those with a disability; for cervical SCI survivors with a disability, aHRs for MI, HF, and AF, respectively, were 2.30, 2.05, and 1.73; for lumbar SCI survivors with a disability, aHRs were 2.79, 2.35, and 2.47.
• Thoracic SCI survivors with disability had a higher risk for MI (aHR, 5.62) and HF (aHR, 3.31) than controls.

IN PRACTICE:

“[T]he recognition and treatment of modifiable cardiovascular risk factors must be reinforced in the SCI population, [and] proper rehabilitation and education should be considered to prevent autonomic dysreflexia or orthostatic hypotension,” the authors wrote.

In an accompanying editorial, Christopher R. West, PhD, and Jacquelyn J. Cragg, PhD, both of the University of British Columbia, Vancouver, Canada, noted that clinical guidelines for cardiovascular and cardiometabolic disease after SCI don’t include approaches to help mitigate the risk for cardiac events such as those reported in the study; therefore, they wrote, the findings “should act as ‘call-to-arms’ to researchers and clinicians to shift gears from tradition and begin studying the clinical efficacy of neuraxial therapies that could help restore autonomic balance [in SCI], such as targeted neuromodulation.”

SOURCE:

The study was led by Jung Eun Yoo, MD, PhD of Seoul National University College of Medicine, Seoul, South Korea, and published online on February 12 in the Journal of the American College of Cardiology.

LIMITATIONS:

The database was not designed for the SCI population, so data are incomplete. The incidence of thoracic SCI was particularly low. Because SCI survivors may have impaired perception of chest pain in ischemic heart disease, those with asymptomatic or silent heart disease may not have been captured during follow-up. All study participants were Korean, so the findings may not be generalizable to other ethnicities.

DISCLOSURES:

This research was partially supported by a grant from the Korea Health Technology R&D Project through the Korea Health Industry Development Institute, funded by the Ministry of Health and Welfare, South Korea. The study authors and the editorialists had no relevant relationships to disclose.

The US Food and Drug Administration has expanded its guidance on medical device sterilization to include vaporized hydrogen peroxide, according to an agency press release issued on January 8.

The update is intended to promote wider use of vaporized hydrogen peroxide (VHP) as a viable alternative to ethylene oxide (EtO). The FDA guidance on sterile devices has been revised to include VHP.

The acceptance of VHP as an Established Category A method of sterilization is another step toward the FDA’s larger goal of reducing EtO, according to the release.

Sterilization is essential for certain medical devices, but the use of EtO, currently the most common method, involves the release of emissions that are potentially harmful to health, and the FDA seeks to identify safe and effective alternatives to reduce risk to the environment and communities where device sterilization occurs. Current Established Category A sterilization methods include moist heat, dry heat, EtO, and radiation. 

FDA

“Vaporized hydrogen peroxide’s addition as an established sterilization method helps us build a more resilient supply chain for sterilized devices that can help prevent medical device shortages,” Suzanne Schwartz, MD, director of the Office of Strategic Partnerships and Technology Innovation in the FDA’s Center for Devices and Radiological Health, said in the press release. “As innovations in sterilization advance, the FDA will continue to seek additional modalities that deliver safe and effective sterilization methods that best protect public health,” she said.

The FDA has supported the development of EtO alternatives since 2019, and remains committed to reducing EtO emissions and also to avoiding potential device shortages, according to the release.

“Ethylene oxide is highly flammable and carcinogenic and poses exposure-related safety concerns for reprocessing staff, as well as environmental risks,” said Venkataraman R. Muthusamy, MD, AGAF, of the University of California, Los Angeles, in an interview. “These risks have led some states or regions to ban or limit its use, but despite these risks, it is currently the most commonly used sterilization technique for medical devices in the United States,” he said. Therefore, coming up with alternatives has been a high priority for the FDA, he added.

VHP has several advantages over EtO, Dr. Muthusamy said. VHP breaks down safely into water and oxygen, with low residual levels after exposure, and has no known oxidation or discoloration effects. In addition, VHP has a low temperature, and should theoretically be safe to use with endoscopes, although data are lacking, he said.

Dr. Muthusamy said that he was not yet too familiar with VHP as a technique, in part because most accessories in GI are single-use.

Primary issues to expanding the use of vaporized hydrogen peroxide as a sterilizing agent in GI clinical practice include availability and the cost of acquiring the devices needed, Dr. Muthusamy told GI & Hepatology News. “Also, the comparative efficacy of this technique in sterilizing GI endoscopes to ethylene oxide and the impact of VHP on scope durability and performance will need to be assessed, and the impact of VHP on the health and safety of reprocessing staff will need to be assessed and monitored,” he said.

There is an interest in the GI community in “green” endoscopy and reducing waste, Dr. Muthusamy said. If an inexpensive, safe, and cost-effective option for sterilization of other devices beyond endoscopes exists, “perhaps we could reduce our use of some disposables as well,” he said.

Dr. Muthusamy had no financial conflicts to disclose.
