Nirmatrelvir-ritonavir (Paxlovid) is associated with a reduced risk for death or hospitalization in the most extremely vulnerable patients with COVID-19, new research suggests.

In a cohort study from British Columbia that included nearly 7,000 patients with COVID-19, nirmatrelvir-ritonavir was associated with a 2.5% reduction in risk for death or emergency hospitalization in clinically extremely vulnerable (CEV) patients who were severely immunocompromised. No significant benefit was observed in patients who were not immunocompromised.

“This finding could help substantially limit unnecessary use of nirmatrelvir and ritonavir in older, otherwise healthy individuals,” lead author Colin R. Dormuth, ScD, associate professor of anesthesiology, pharmacology, and therapeutics at the University of British Columbia, Vancouver, told this news organization. “Another finding that was surprising and might help place the role of nirmatrelvir and ritonavir in context is that even in severely immunocompromised individuals who did not take [the drug], the risk of death or hospitalization with COVID-19 was less than 4% in our study population.”

The study was published online in JAMA Network Open.
 

Who benefits?

The investigators analyzed medical records for 6,866 patients in British Columbia (median age, 70 years; 57% women) who presented between Feb. 1, 2022, and Feb. 3, 2023. Eligible patients belonged to one of four higher-risk groups who received priority for COVID-19 vaccination.

Two groups included CEV patients who were severely (CEV1) or moderately (CEV2) immunocompromised. The CEV3 group was not immunocompromised but had medical conditions associated with a high risk for complications from COVID-19. A fourth expanded eligibility (EXEL) group included higher-risk patients who were not in one of the other groups, such as unvaccinated patients older than age 70 years.

The investigators matched treated patients to untreated patients in the same vulnerability group according to age, sex, and month of infection. The primary outcome was death from any cause or emergency hospitalization with COVID-19 within 28 days.

Treatment with nirmatrelvir-ritonavir was associated with statistically significant relative reductions in the primary outcome, compared with no treatment, for patients in the CEV1 (risk difference, −2.5%) and CEV2 (RD, −1.7%) groups. In the CEV3 group, the RD of −1.3% was not statistically significant. In the EXEL group, treatment was associated with a higher risk for the primary outcome (RD, 1.0%), but the result was not statistically significant.

The results were “robust across sex and older vs. younger age,” the authors note. “No reduction in the primary outcome was observed in lower-risk individuals, including those aged 70 years or older without serious comorbidities.”

The combination of nirmatrelvir-ritonavir was approved for use in Canada based on interim efficacy and safety data from the Evaluation of Inhibition for COVID-19 in High-Risk Patients (EPIC-HR) trial, said Dr. Dormuth.

British Columbia’s eligibility criteria for nirmatrelvir-ritonavir coverage differ substantially from the criteria for participants in the EPIC-HR trial, he noted. Those patients were unvaccinated, had no natural immunity from a previous COVID-19 infection, and were infected with COVID-19 variants that were different from those now circulating. The current study was prompted by the need to look at a broader population of individuals in British Columbia with varying risks of complications from COVID-19 infection.

Before the study, a common view was that patients aged 70 and older would benefit from the drug, said Dr. Dormuth. “Our study, which accounted for medical conditions related to an individual’s vulnerability to complications, showed that older age on its own was not a reason to use nirmatrelvir and ritonavir once relevant medical conditions were taken into consideration.”

The researchers are working on a study to identify with greater specificity which comorbid conditions are most associated with nirmatrelvir-ritonavir effectiveness, he added. “It could be that a relatively small number of conditions can be used to identify most individuals who would benefit from the drug.”
 

‘Signal toward benefit’

Commenting on the findings for this news organization, Abhijit Duggal, MD, vice chair of critical care at the Cleveland Clinic, who was not involved in this study, said, “I’m always very wary when we look at observational data and we start saying the effectiveness is not really as high as was seen in other studies. We are seeing an effect with all these studies that seems to be in the right direction.

“Having said that,” he added, “is the effect going to be potentially more in patients at higher risk? Absolutely. I think these postmarket studies are really showing that after vaccination, if someone does get infected, this is a secondary option available to us that can prevent progression of the disease, which would likely be more severe in immunocompromised patients.”

Dr. Duggal was a coinvestigator on a recent study of more than 68,000 patients that showed that nirmatrelvir-ritonavir or molnupiravir was associated with reductions in mortality and hospitalization in nonhospitalized patients infected with the Omicron variant, regardless of age, race and ethnicity, virus strain, vaccination status, previous infection status, or coexisting conditions.

“In all groups, there was a signal toward benefit,” said Dr. Duggal. “These studies tell us that these drugs do remain valid options. But their use needs to be discussed on a case-by-case basis with patients we feel are deteriorating or at a higher risk because of underlying disease processes.”

The study was supported by funding from the British Columbia Ministry of Health. Dr. Dormuth and Dr. Duggal report no relevant financial relationships.

TOPLINE:

Individuals who visited the ER for substance-induced psychosis had a 160% greater risk of developing a schizophrenia spectrum disorder (SSD), compared with the general population, new research shows. Three years after an initial ER visit, 18.5% of those with substance-induced psychosis were diagnosed with an SSD. Cannabis-induced psychosis was associated with the greatest risk.

METHODOLOGY:

• In this retrospective, population-based cohort study, investigators evaluated the risk of transition to a diagnosis of SSD for individuals with an ER visit for substance use versus the general population.
• Investigators at The Ottawa Hospital and the Institute for Clinical Evaluative Sciences, both in Ontario, analyzed data from six linked databases containing health information on nearly 10 million Ontario residents aged 14-65 years eligible for medical coverage.
• Investigators collected the health data between January 2008 and March 2022 on residents with substance use–related ER visits with, and without, psychosis.

TAKEAWAY:

• There were nearly 408,000 individuals with an ER visit for substance use, of which 13,800 (3.4%) of the visits were for substance-induced psychosis.
• Individuals with substance-induced psychosis were at a 163-fold (age- and sex-adjusted hazard ratio, 163.2; 95% confidence interval, 156.1-170.5) increased risk of transitioning to an SSD, relative to the general population (3-year risk, 18.5% vs. 0.1%).
• Individuals with an ER visit for substance use without psychosis had a lower relative risk of transitioning (aHR, 9.8; 95% CI, 9.5-10.2; 3-year risk, 1.4%) but incurred more than three times the absolute number of transitions (9,969 vs. 3,029).
• ER visits related to cannabis use had the highest transition risk among visits with psychosis (aHR, 241.6; 95% CI, 225.5-258.9) and the third-highest risk among visits without psychosis (aHR, 14.3; 95% CI, 13.5-15.2).
• Younger age and male sex were associated with a higher risk of transition, and the risk of male sex was greater in younger, compared with older, individuals particularly for cannabis use.

IN PRACTICE:

“Primary prevention efforts aimed at reducing substance use and substance use disorders could substantially reduce the population-level burden of chronic psychoses,” the investigators write. “Our findings also highlight the need for targeted secondary prevention providing early intervention and reducing substance use in the highest-risk groups, which may delay or prevent transition to schizophrenia spectrum disorders.”

SOURCE:

Daniel T. Myran, MD, MPH, of the Ottawa Hospital Research Institute, led the study, which was funded by the Canadian Institutes of Health Research and the University of Ottawa department of family medicine. The study was published online in JAMA Psychiatry.

LIMITATIONS:

Investigators did not have access to detailed data on substance-related outpatient visits or patterns of substance use, which could provide additional prognostic information.

DISCLOSURES:

Dr. Myran reported receiving grants from the Canadian Institutes of Health Research during the conduct of the study. Dr. Solmi reported receiving honoraria for participation on advisory boards or presentations from AbbVie, Angelini, Lundbeck, and Otsuka outside the submitted work. The remaining authors have disclosed no relevant financial relationships.

TOPLINE:

Research from South Korea provides additional evidence for the connection between COVID-19 and an increased risk for autoimmune conditions post infection.

METHODOLOGY:

• In this retrospective study, researchers identified 354,527 individuals diagnosed with COVID-19 via polymerase chain reaction (PCR) testing from Oct. 8, 2020, to Dec. 31, 2021.
• Researchers compared the COVID-19 group with 6,134,940 healthy individuals who had no evidence of COVID-19 to quantify the risk for autoimmune and autoinflammatory connective tissue disorders.
• Patients were followed until diagnosis, death, or end of study period (Dec. 31, 2021).

TAKEAWAY:

• Risks for alopecia areata, alopecia totalis, antineutrophil cytoplasmic antibody–associated vasculitis, Crohn’s disease, and sarcoidosis were higher in the COVID-19 group.
• Patients with more severe COVID-19 (admitted to the ICU) were at greater risk for many autoimmune conditions, including alopecia totalis, psoriasis, vitiligo, and vasculitis.
•  

IN PRACTICE:

“Our results emphasize the need to focus on managing not only the acute stages of COVID-19 itself but also autoimmune diseases as complications of COVID-19,” the authors wrote.

SOURCE:

Sung Ha Lim, MD, of Yonsei University, Wonju, South Korea, was the first author of the study, published in JAMA Network Open.

LIMITATIONS:

The study was retrospective and was composed almost exclusively of individuals from a single ethnicity. The study could have included individuals with COVID-19 in the control group who did not undergo PCR testing. The analysis did not include detailed information on each patient, including genetic information, that could have contributed to autoimmune disease risk.

DISCLOSURES:

The study was supported by a fund from the research program of the Korea Medical Institute and by grants from the Korea Health Industry Development Institute, the Korean Ministry of Health & Welfare, and the National Research Foundation of Korea.

With physicians under increasing pressure to see more patients in shorter office visits, developing a social media presence may offer valuable opportunities to connect with patients, explain procedures, combat misinformation, talk through a published article, and even share a joke or meme.

But there are caveats for doctors posting on social media platforms. This news organization spoke to four doctors who successfully use social media. Here is what they want you to know before you post – and how to make your posts personable and helpful to patients and your practice simultaneously.
 

Use social media for the right reasons

While you’re under no obligation to build a social media presence, if you’re going to do it, be sure your intentions are solid, said Don S. Dizon, MD, professor of medicine and professor of surgery at Brown University, Providence, R.I. Dr. Dizon, as @DoctorDon, has 44,700 TikTok followers and uses the platform to answer cancer-related questions.

If you don’t know where to start, consider seeking a digital mentor to talk through your options.

“You may never meet this person, but you should choose them if you like their style, their content, their delivery, and their perspective,” Dr. Dizon said. “Find another doctor out there on social media whom you feel you can emulate. Take your time, too. Soon enough, you’ll develop your own style and your own online persona.”
 

Post clear, accurate information

If you want to be lighthearted on social media, that’s your choice. But Jennifer Trachtenberg, a pediatrician with nearly 7,000 Instagram followers in New York who posts as @askdrjen, prefers to offer vaccine scheduling tips, alert parents about COVID-19 rates, and offer advice on cold and flu prevention.

“Right now, I’m mainly doing this to educate patients and make them aware of topics that I think are important and that I see my patients needing more information on,” she said. “We have to be clear: People take what we say seriously. So, while it’s important to be relatable, it’s even more important to share evidence-based information.”
 

Many patients get their information on social media

While patients once came to the doctor armed with information sourced via “Doctor Google,” today, just as many patients use social media to learn about their condition or the medications they’re taking.

Unfortunately, a recent Ohio State University, Columbus, study found that the majority of gynecologic cancer advice on TikTok, for example, was either misleading or inaccurate.

“This misinformation should be a motivator for physicians to explore the social media space,” Dr. Dizon said. “Our voices need to be on there.”
 

Break down barriers – and make connections

Mike Natter, MD, an endocrinologist in New York, has type 1 diabetes. This informs his work – and his life – and he’s passionate about sharing it with his 117,000 followers as @mike.natter on Instagram.

“A lot of type 1s follow me, so there’s an advocacy component to what I do,” he said. “I enjoy being able to raise awareness and keep people up to date on the newest research and treatment.”

But that’s not all: Dr. Natter is also an artist who went to art school before he went to medical school, and his account is rife with his cartoons and illustrations about everything from valvular disease to diabetic ketoacidosis.

“I found that I was drawing a lot of my notes in medical school,” he said. “When I drew my notes, I did quite well, and I think that using art and illustration is a great tool. It breaks down barriers and makes health information all the more accessible to everyone.”
 

Share your expertise as a doctor – and a person

As a mom and pediatrician, Krupa Playforth, MD, who practices in Vienna, Va., knows that what she posts carries weight. So, whether she’s writing about backpack safety tips, choking hazards, or separation anxiety, her followers can rest assured that she’s posting responsibly.

“Pediatricians often underestimate how smart parents are,” said Dr. Playforth, who has three kids, ages 8, 5, and 2, and has 137,000 followers on @thepediatricianmom, her Instagram account. “Their anxiety comes from an understandable place, which is why I see my role as that of a parent and pediatrician who can translate the knowledge pediatricians have into something parents can understand.”

Dr. Playforth, who jumped on social media during COVID-19 and experienced a positive response in her local community, said being on social media is imperative if you’re a pediatrician.

“This is the future of pediatric medicine in particular,” she said. “A lot of pediatricians don’t want to embrace social media, but I think that’s a mistake. After all, while parents think pediatricians have all the answers, when we think of our own children, most doctors are like other parents – we can’t think objectively about our kids. It’s helpful for me to share that and to help parents feel less alone.”

If you’re not yet using social media to the best of your physician abilities, you might take a shot at becoming widely recognizable. Pick a preferred platform, answer common patient questions, dispel medical myths, provide pertinent information, and let your personality shine.

With physicians under increasing pressure to see more patients in shorter office visits, developing a social media presence may offer valuable opportunities to connect with patients, explain procedures, combat misinformation, talk through a published article, and even share a joke or meme.

But there are caveats for doctors posting on social media platforms. This news organization spoke to four doctors who successfully use social media. Here is what they want you to know before you post – and how to make your posts personable and helpful to patients and your practice simultaneously.
 

Use social media for the right reasons

While you’re under no obligation to build a social media presence, if you’re going to do it, be sure your intentions are solid, said Don S. Dizon, MD, professor of medicine and professor of surgery at Brown University, Providence, R.I. Dr. Dizon, as @DoctorDon, has 44,700 TikTok followers and uses the platform to answer cancer-related questions.

“It should be your altruism that motivates you to post,” said Dr. Dizon, who is also associate director of community outreach and engagement at the Legorreta Cancer Center in Providence, R.I., and director of medical oncology at Rhode Island Hospital. “What we can do for society at large is to provide our input into issues, add informed opinions where there’s controversy, and address misinformation.”

In July 2023, nirsevimab (Beyfortus), a monoclonal antibody, was approved by the Food and Drug Administration for the prevention of respiratory syncytial virus (RSV) disease in infants and children younger than 2 years of age. On Aug. 3, 2023, the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention recommended routine use of it for all infants younger than 8 months of age born during or entering their first RSV season. Its use is also recommended for certain children 8-19 months of age who are at increased risk for severe RSV disease at the start of their second RSV season. Hearing the approval, I immediately had a flashback to residency, recalling the multiple infants admitted each fall and winter exhibiting classic symptoms including cough, rhinorrhea, nasal flaring, retractions, and wheezing with many having oxygen requirements and others needing intubation. Only supportive care was available.

RSV is the leading cause of infant hospitalizations. Annually, the CDC estimates there are 50,000-80,000 RSV hospitalizations and 100-300 RSV-related deaths in the United States in persons younger than 5 years of age. While premature infants have the highest rates of hospitalization (three times a term infant) about 79% of hospitalized children younger than 2 years have no underlying medical risks.¹ The majority of children will experience RSV as an upper respiratory infection within the first 2 years of life. However, severe disease requiring hospitalization is more likely to occur in premature infants and children younger than 6 months; children younger than 2 with congenital heart disease and/or chronic lung disease; children with severe cystic fibrosis; as well as the immunocompromised child and individuals with neuromuscular disorders that preclude clearing mucous secretions or have difficulty swallowing.

Palivizumab (Synagis), the first monoclonal antibody to prevent RSV in infants was licensed in 1998. Its use was limited to infants meeting specific criteria developed by the American Academy of Pediatrics. Only 5% of infants had access to it. It was a short-acting agent requiring monthly injections, which were very costly ($1,661-$2,584 per dose). Eligible infants could receive up to five injections per season. Several studies proved its use was not cost beneficial.

What are the advantages of nirsevimab? It’s a long-acting monoclonal antibody. Only one dose is required per season. Costs will significantly diminish. It is recommended for all infants younger than 8 months of age born during RSV season. Those children 8-19 months at risk for severe RSV disease can receive it prior to the start of their second RSV season. During RSV season (October 1 to March 31), the initial dose should be administered to newborns just prior to hospital discharge. Older infants and newborns who did not receive it prior to hospital discharge can receive it at their medical home. Newborns should receive it within the first week of life. It is covered by the Vaccine for Children Program. Simultaneous administration with routine childhood immunizations is recommended. Finally, RSV season may vary in tropical areas (Southern Florida, Puerto Rico. etc.) and Alaska. The timing of nirsevimab administration should be based on local RSV activity provided by state and local authorities.

In addition, the FDA approved an RSV vaccine (Abrysvo) for use in adults at least 60 years of age and in pregnant women at 32-36 weeks’ gestation. The latter is administered to prevent lower respiratory tract infection in infants from birth to 6 months. Recommendations have been published for administration in nonpregnant adults. Specific information is forthcoming in terms timing of administration of nirsevimab in infants whose mothers receive Abrysvo.

RSV season is quickly approaching. Detailed recommendations for administration and FAQ questions related to nirsevimab and palivizumab can be found at https://www.aap.org or https://www.cdc.gov/vaccines/hcp/acip-recs/index.html.
 

Influenza

So, what about influenza? Vaccine composition has been tweaked to match the circulating viruses but the recommended age for annual routine administration remains unchanged. All persons at least 6 months of age should be vaccinated. Children between 6 months and 8 years need two doses at least 4 weeks apart when receiving vaccine for the first time. Immunizing everyone in the household is encouraged especially if there are household contacts at risk for developing severe disease, including infants too young to be vaccinated. Keep in mind children may be coinfected with multiple viruses. Adams and colleagues reviewed the prevalence of coinfection of influenza and Sars-CoV-2 in persons younger than 18 years reported to three CDC surveillance platforms during the 2021-2022 season.² Thirty-two of 575 hospitalized (6%) coinfections were analyzed and 7 of 44 (16%) deaths. Compared with patients without coinfections, the coinfected patients were more likely to require mechanical ventilation (13% vs. 4%) or CPAP (16% vs. 6%). Only 4 of 23 who were influenza vaccine eligible were vaccinated. Of seven coinfected children who died, none had received influenza vaccine and only one received an antiviral. Only 5 of 31 (16%) infected only with influenza were vaccinated.³

Influenza activity was lower than usual during the 2021-2022 season. However, this report revealed underuse of both influenza vaccine and antiviral therapy, both of which are routinely recommended.
 

COVID-19

What’s new with COVID-19? On Sept. 12, 2023, ACIP recommended that everyone at least 6 months of age receive the 2023-2024 (monovalent, XBB containing) COVID-19 vaccines. Children at least 5 years of age need one dose and those younger need one or two doses depending on the number of doses previously received. Why the change? Circulating variants continue to change. There is a current uptick in cases including hospitalizations (7.7%) and deaths (4.5%) and it’s just the beginning of the season.⁴ Symptoms, risk groups and complications have not changed. The primary goal is to prevent infection, hospitalization, long term complications, and death.

We are now armed with the most up-to-date interventions to help prevent the acquisition of these three viruses. Our next step is recommending and delivering them to our patients.

Only 4 of 23 who were influenza vaccine eligible were vaccinated. Of seven coinfected children who died, none had received influenza vaccine and only one received an antiviral. Only 5 of 31 (16%) infected only with influenza were vaccinated.³

Influenza activity was lower than usual during the 2021-2022 season. However, this report revealed underuse of both influenza vaccine and antiviral therapy, both of which are routinely recommended.
 

COVID-19

What’s new with COVID-19? On Sept. 12, 2023, ACIP recommended that everyone at least 6 months of age receive the 2023-2024 (monovalent, XBB containing) COVID-19 vaccines. Children at least 5 years of age need one dose and those younger need one or two doses depending on the number of doses previously received. Why the change? Circulating variants continue to change. There is a current uptick in cases including hospitalizations (7.7%) and deaths (4.5%) and it’s just the beginning of the season.⁴ Symptoms, risk groups and complications have not changed. The primary goal is to prevent infection, hospitalization, long term complications, and death.

We are now armed with the most up-to-date interventions to help prevent the acquisition of these three viruses. Our next step is recommending and delivering them to our patients.

She went by the name “Dr. Roxy” on social media and became something of a sensation on TikTok, where she livestreamed her patients’ operations. Ultimately, however, plastic surgeon Katharine Roxanne Grawe, MD, lost her medical license based partly on her “life-altering, reckless treatment,” heightened by her social media fame. In July, the Ohio state medical board permanently revoked Dr. Grawe’s license after twice reprimanding her for her failure to meet the standard of care. The board also determined that, by livestreaming procedures, she placed her patients in danger of immediate and serious harm.

Although most doctors don’t use social media to the degree that Dr. Grawe did, using the various platforms – from X (formerly Twitter) to Facebook, Instagram, and TikTok – can be a slippery slope. Medscape’s Physician Behavior Report 2023 revealed that doctors have seen their share of unprofessional or offensive social media use from their peers. Nearly 7 in 10 said it is unethical for a doctor to act rudely, offensively, or unprofessionally on social media, even if their medical practice isn’t mentioned. As one physician put it: “Professional is not a 9-to-5 descriptor.”

In today’s world, social media use is almost a given. Doctors must tread cautiously when they approach it – maybe even more so. “There’s still a stigma attached,” said Liudmila Schafer, MD, an oncologist with The Doctor Connect, a career consulting firm. “Physicians face a tougher challenge due to societal expectations of perfection, with greater consequences for mistakes. We’re under constant ‘observation’ from peers, employers, and patients.”

Beverly Hills plastic surgeon Jay Calvert, MD, says he holds firm boundaries with how he uses social media. “I do comedy on the side, but it’s not acceptable for me as a doctor to share that on social media,” he said. “People want doctors who are professional, and I’m always concerned about how I present myself.”

Dr. Calvert said it is fairly easy to spot doctors who cross the line with social media. “You have to hold yourself back when posting. Doing things like dancing in the OR are out of whack with the profession.”

According to Dr. Schafer, a definite line to avoid crossing is offering medical advice or guidance on social media. “You also can’t discuss confidential practice details, respond to unfamiliar contacts, or discuss institutional policies without permission,” she said. “It’s important to add disclaimers if a personal scientific opinion is shared without reference [or] research or with unchecked sources.”
 

Navigating the many social media sites

Each social media platform has its pros and cons. Doctors need to determine why to use them and what the payback of each might be. Dr. Schafer uses multiple sites, including LinkedIn, Facebook, Instagram, X, Threads, YouTube, and, to a lesser degree, Clubhouse. How and what she posts on each varies. “I use them almost 95% professionally,” she said. “It’s challenging to meet and engage in person, so that is where social media helps.”

Stephen Pribut, MD, a Washington-based podiatrist, likes to use X as an information source. He follows pretty simple rules when it comes to what he tweets and shares on various sites: “I stay away from politics and religion,” he said. “I also avoid controversial topics online, such as vaccines.”

Joseph Daibes, DO, who specializes in cardiovascular medicine at New Jersey Heart and Vein, Clifton, said he has changed how he uses social media. “Initially, I was a passive consumer, but as I recognized the importance of accurate medical information online, I became more active in weighing in responsibly, occasionally sharing studies, debunking myths, and engaging in meaningful conversations,” he said. “Social media can get dangerous, so we have a duty to use it responsibly, and I cannot stress that enough.”

For plastic surgeons like Dr. Calvert, the visual platforms such as Instagram can prove invaluable for marketing purposes. “I’ve been using Instagram since 2012, and it’s been my most positive experience,” he said. “I don’t generate business from it, but I use it to back up my qualifications as a surgeon.”

Potential patients like to scroll through posts by plastic surgeons to learn what their finished product looks like, Dr. Calvert said. In many cases, plastic surgeons hire social media experts to cultivate their content. “I’ve hired and fired social media managers over the years, ultimately deciding I should develop my own content,” he said. “I want people to see the same doctor on social media that they will see in the office. I like an authentic presentation, not glitzy.”
 

Social media gone wrong

Dr. Calvert said that in the world of plastic surgery, some doctors use social media to present “before and after” compilations that in his opinion aren’t necessarily fully authentic, and this rubs him wrong. “There’s a bit of ‘cheating’ in some of these posts, using filters, making the ‘befores’ particularly bad, and other tricks,” he said.

Dr. Daibes has also seen his share of social media misuse: ”Red flags include oversharing personal indulgences, engaging in online spats, or making unfounded medical claims,” he said. “It’s essential to remember our role as educators and advocates, and to present ourselves in a way that upholds the dignity of our profession.”

At the end of the day, social media can have positive uses for physicians, and it is clearly here to stay. The onus for responsible use ultimately falls to the physicians using it.

Dr. Daibes emphasizes the fact that a doctor’s words carry weight – perhaps more so than those of other professionals. “The added scrutiny is good because it keeps us accountable; it’s crucial that our information is accurate,” he said. “The downside is that the scrutiny can be stifling at times and lead to self-censorship, even on nonmedical matters.”

Physicians have suggested eight guidelines for doctors to follow when using social media:

• Remember that you represent your profession, even if posting on personal accounts.
• Never post from the operating room, the emergency department, or any sort of medical space.
• If you’re employed, before you post, check with your employer to see whether they have any rules or guidance surrounding social media.
• Never use social media to badmouth colleagues, hospitals, or other healthcare organizations.
• Never use social media to dispense medical advice.
• Steer clear of the obvious hot-button issues, like religion and politics.
• Always protect patient privacy when posting.
• Be careful with how and whom you engage on social media.

The American Heart Association has released a focused update on managing patients with cardiac arrest or life-threatening toxicity due to poisoning.

The update reflects treatment advances and new knowledge, including the use of venoarterial extracorporeal membrane oxygenation (VA-ECMO) for patients whose condition is refractory to poison antidotes and other therapies.

The new guidelines are designed primarily for North American health care professionals who treat adults and children who are critically ill because of poisoning, including intentional and unintentional drug overdose, chemical exposure, and drug-drug interactions, the authors note.

Published online in Circulation, the update was endorsed by the American Academy of Pediatrics.
 

‘Nearly miraculous’

“It’s been 13 years since the poisoning treatment guidelines had a comprehensive update,” lead author Eric J. Lavonas, MD, professor of emergency medicine at Denver Health and the Rocky Mountain Poison and Drug Center, Colo., told this news organization. “In that time, we’ve learned a lot about how to best use antidotes and other treatments to save the most critically poisoned patients.”

Highlighting a few key points from the update, he said, “For those rare situations when antidotes aren’t enough, the new guidelines include the use of heart-lung machines (VA-ECMO) for patients with beta-blocker, calcium channel blocker, or sodium channel blocker poisoning causing cardiogenic shock.”

Furthermore, he said, “High-dose insulin treatment for patients with beta-blocker and calcium channel blocker poisoning [also recommended in the update] has really become mainstream. The doses are up to 10 times higher than the amount used to treat diabetic emergencies.

“Some excellent science has shown that giving IV lipid emulsion can save the life of someone with an accidental overdose of local anesthetic medications, particularly bupivacaine,” he added. “The result is sometimes nearly miraculous.

“But when this treatment is extended to poisoning from other medications, it often doesn’t work as well, and in some situations may make things worse,” he said. “The issue may be that giving lipids increases absorption of drug from the stomach and intestines, which can be dangerous when the patient took an overdose of pills.”
 

Low level of evidence

The guidelines were compiled by the Critical Poisoning Writing Group, which includes experts from emergency medicine, pediatrics, medical toxicology, pharmacology, critical care, emergency medical services, education, research, and nursing. Group members were appointed by the AHA Emergency Cardiovascular Care Science Subcommittee and were approved by the AHA Manuscript Oversight Committee.

First and foremost, the group recommends timely consultation with a medical toxicologist, a clinical toxicologist, or a regional poison center to facilitate rapid, effective therapy, because treatment of cardiac arrest and toxicity from poisoning often requires treatments that most clinicians don’t use frequently.

Other key points include the following:

• Naloxone administration may reverse respiratory arrest due to opioid overdose, preventing progression to cardiac arrest.
• Give high-dose insulin therapy early in the treatment of patients with beta-blocker and calcium channel blocker poisoning, Dr. Lavonas noted.
• Standard advanced life support plus sodium bicarbonate is appropriate for life-threatening dysrhythmias caused by cocaine or other sodium channel blockers.
• If cyanide poisoning is suspected, clinicians should not wait for confirmatory testing; treatment should begin immediately with hydroxocobalamin (preferred) or sodium nitrite plus sodium thiosulfate.
• Digoxin-specific immune antibody fragments can reverse life-threatening dysrhythmias from digoxin poisoning.
• Use of 20% intravenous lipid emulsion can be efficacious in the resuscitation of life-threatening local anesthetic toxicity, especially from bupivacaine, Dr. Lavonas indicated.
• Sedation is recommended for patients with severe agitation from sympathomimetic poisoning to manage hyperthermia and acidosis, prevent rhabdomyolysis and injury, and allow evaluation for other life-threatening conditions.
• Although flumazenil reverses central nervous system and respiratory depression from benzodiazepine poisoning, risks and contraindications, provided in the guidelines, limit its use.
• VA-ECMO can be lifesaving for patients with cardiogenic shock or dysrhythmias that are refractory to other treatments.

“Unfortunately, despite improvements in the design and funding support for resuscitation research, the overall certainty of the evidence base for resuscitation science and management of critical poisoning is low,” the group acknowledges.

Of the 73 guideline recommendations, only 2 are supported by level A evidence; 3 are supported by level B-randomized evidence, 12 by level B-nonrandomized evidence, and the rest by level C evidence.

“Accordingly, the strength of recommendations is weaker than optimal,” they write. “Clinical trials in resuscitation and the management of critical poisoning are sorely needed.”
 

‘Don’t go it alone!’

“Most critical poisonings are pretty uncommon, and each patient is different,” Dr. Lavonas said. “Even in the emergency department or ICU, most physicians will treat a patient who is critically ill with any given poison less than once a year. The antidotes and medication doses needed to effectively treat these patients are often very different than everyday medical practice.

“Don’t try to go it alone!” he urges. “Poisoning cases are complex, and the treatments work best when they are implemented quickly and assertively. A toxicologist can help sort through complex situations and get effective treatment started without delay.”

Every certified poison center has a medical toxicologist or clinical toxicologist on call 24/7 to give advice to physicians and hospitals about patients who are critically ill after being poisoned, he added. “Everyone in the U.S. has access to a poison center by calling one number: 1-800-222-1222.”

Dr. Lavonas has disclosed no relevant financial relationships.

First and foremost, the group recommends timely consultation with a medical toxicologist, a clinical toxicologist, or a regional poison center to facilitate rapid, effective therapy, because treatment of cardiac arrest and toxicity from poisoning often requires treatments that most clinicians don’t use frequently.

Other key points include the following:

• Naloxone administration may reverse respiratory arrest due to opioid overdose, preventing progression to cardiac arrest.
• Give high-dose insulin therapy early in the treatment of patients with beta-blocker and calcium channel blocker poisoning, Dr. Lavonas noted.
• Standard advanced life support plus sodium bicarbonate is appropriate for life-threatening dysrhythmias caused by cocaine or other sodium channel blockers.
• If cyanide poisoning is suspected, clinicians should not wait for confirmatory testing; treatment should begin immediately with hydroxocobalamin (preferred) or sodium nitrite plus sodium thiosulfate.
• Digoxin-specific immune antibody fragments can reverse life-threatening dysrhythmias from digoxin poisoning.
• Use of 20% intravenous lipid emulsion can be efficacious in the resuscitation of life-threatening local anesthetic toxicity, especially from bupivacaine, Dr. Lavonas indicated.
• Sedation is recommended for patients with severe agitation from sympathomimetic poisoning to manage hyperthermia and acidosis, prevent rhabdomyolysis and injury, and allow evaluation for other life-threatening conditions.
• Although flumazenil reverses central nervous system and respiratory depression from benzodiazepine poisoning, risks and contraindications, provided in the guidelines, limit its use.
• VA-ECMO can be lifesaving for patients with cardiogenic shock or dysrhythmias that are refractory to other treatments.

“Unfortunately, despite improvements in the design and funding support for resuscitation research, the overall certainty of the evidence base for resuscitation science and management of critical poisoning is low,” the group acknowledges.

Of the 73 guideline recommendations, only 2 are supported by level A evidence; 3 are supported by level B-randomized evidence, 12 by level B-nonrandomized evidence, and the rest by level C evidence.

“Accordingly, the strength of recommendations is weaker than optimal,” they write. “Clinical trials in resuscitation and the management of critical poisoning are sorely needed.”
 

‘Don’t go it alone!’

“Most critical poisonings are pretty uncommon, and each patient is different,” Dr. Lavonas said. “Even in the emergency department or ICU, most physicians will treat a patient who is critically ill with any given poison less than once a year. The antidotes and medication doses needed to effectively treat these patients are often very different than everyday medical practice.

“Don’t try to go it alone!” he urges. “Poisoning cases are complex, and the treatments work best when they are implemented quickly and assertively. A toxicologist can help sort through complex situations and get effective treatment started without delay.”

Every certified poison center has a medical toxicologist or clinical toxicologist on call 24/7 to give advice to physicians and hospitals about patients who are critically ill after being poisoned, he added. “Everyone in the U.S. has access to a poison center by calling one number: 1-800-222-1222.”

Dr. Lavonas has disclosed no relevant financial relationships.

TOPLINE:

A new study finds SARS-CoV-2 directly infects the coronary vasculature and causes plaque inflammation, which could help explain why people with COVID-19 have an increased risk for ischemic cardiovascular complications up to 1 year after infection.

METHODOLOGY:

• Researchers obtained 27 coronary autopsy specimens from eight patients who died from COVID-19, mean age 70 years and 75% male. All had coronary artery disease and most had cardiovascular risk factors such as hypertension, were overweight or obese, and had hyperlipidemia and type 2 diabetes.
• All but one patient, who was pronounced dead before hospital admission, were hospitalized for an average of 17.6 days.
• To identify SARS-CoV-2 viral RNA (vRNA) in the autoptic coronary vasculature, researchers performed RNA fluorescence in situ hybridization (RNA-FISH) analysis for the vRNA encoding the spike (S) protein; they also probed the antisense strand of the S gene (S antisense), which is only produced during viral replication.

TAKEAWAY:

• The study found evidence of SARS-CoV-2 replication in all analyzed human autopsy coronaries regardless of their pathological classification, although viral replication was highest in early-stage lesions that progress to more advanced atherosclerotic plaques.
• Findings indicated that more than 79% of macrophages (white blood cells that help remove lipids) and more than 90% of foam cells (lipid-laden macrophages that are a hallmark of atherosclerosis at all stages of the disease) are S+, and more than 40% of both cell types are S antisense+, indicating SARS-CoV-2 can infect macrophages at a high rate.
• SARS-CoV-2 induced a strong inflammatory response as evidenced by release of cytokines (including interleukin-1 beta and interluekin-6 that are linked to myocardial infarction) in both macrophages and foam cells, which may contribute to the ischemic cardiovascular complications in patients with COVID-19.

IN PRACTICE:

“Our data conclusively demonstrate that SARS-CoV-2 is capable of infecting and replicating in macrophages within the coronary vasculature of patients with COVID-19,” write the authors, adding that SARS-CoV-2 preferentially replicates in foam cells, compared with other macrophages, suggesting these cells “might act as a reservoir of SARS-CoV-2 viral debris in the atherosclerotic plaque.”

SOURCE:

The study was led by Natalia Eberhardt, PhD, postdoctoral fellow, department of medicine, division of cardiology, New York University, and colleagues. It was published online in Nature Cardiovascular Research.

LIMITATIONS:

Findings are relevant only to the original strains of SARS-CoV-2 that circulated in New York between May 2020 and May 2021, and are not generalizable to patients younger and healthier than those from whom samples were obtained for the study.

DISCLOSURES:

The study received support from the National Institutes of Health. The authors report no relevant financial relationships.

The artificial intelligence chatbot ChatGPT (OpenAI) may serve as a reliable clinical decision-support tool for assessing patients who present to the emergency department with acute ulcerative colitis (UC).

In a small study, ChatGPT version 4 (GPT-4) accurately gauged disease severity and made decisions about the need for hospitalization that were largely in line with expert gastroenterologists.

“Our findings suggest that GPT-4 has potential as a clinical decision-support tool in assessing UC severity and recommending suitable settings for further treatment,” say the authors, led by Asaf Levartovsky, MD, department of gastroenterology, Sheba Medical Center, Tel Aviv University.

The study was published online in the American Journal of Gastroenterology.
 

Assessing its potential

UC is a chronic inflammatory bowel disease known for episodes of flare-ups and remissions. Flare-ups often result in a trip to the ED, where staff must rapidly assess disease severity and need for hospital admission.

Dr. Levartovsky and colleagues explored how helpful GPT-4 could be in 20 distinct presentations of acute UC in the ED. They assessed the chatbot’s ability to determine the severity of disease and whether a specific presentation warranted hospital admission for further treatment.

They fed GPT-4 case summaries that included crucial data such as symptoms, vital signs, and laboratory results. For each case, they asked the chatbot to assess disease severity based on established criteria and recommend hospital admission or outpatient care.

The GPT-4 answers were compared with assessments made by gastroenterologists and the actual decision regarding hospitalization made by the physician in the ED.

Overall, ChatGPT categorized acute UC as severe in 12 patients, as moderate in 7, and as mild in 1. In each case, the chatbot provided a detailed answer depicting severity of every variable of the criteria and an overall severity classification.

ChatGPT’s assessments were consistent with gastroenterologists’ assessments 80% of the time, with a “high degree of reliability” between the two assessments, the study team reports.

The average correlation between ChatGPT and physician ratings was 0.839 (P < .001). Inconsistencies in four cases stemmed largely from inaccurate cut-off values for systemic variables (such as hemoglobin and tachycardia).

Following severity assessment, ChatGPT leaned toward hospital admission for 16 patients, whereas in actual clinical practice, only 12 patients were hospitalized. In one patient with moderate UC who was discharged, ChatGPT was in favor of hospitalization, based on the patient’s age and comorbid conditions. For two moderate UC cases, the chatbot recommended consultation with a health care professional for further evaluation and management, which the researchers deemed to be an indecisive response.

Based on their findings, the researchers say ChatGPT could serve as a real-time decision support tool – one that is not meant to replace physicians but rather enhance human decision-making.

They note that the small sample size is a limitation and that ChatGPT’s accuracy rate requires further validation across larger samples and diverse clinical scenarios.

The study had no specific funding. The authors report no relevant financial relationships.

The hugely popular weight loss agent semaglutide (approved as Wegovy for weight loss; Ozempic for type 2 diabetes; Novo Nordisk) received a pair of drug safety–related labeling additions from the Food and Drug Administration in late September for the Ozempic formulation.

The FDA added a warning to the drug-interaction section of the Ozempic label that reiterates a warning that is already in place in other label sections, reinforcing the message that the glucagon-like peptide-1 (GLP-1) receptor agonist Ozempic can potentially interact with the action of certain other agents to increase a person’s risk for hypoglycemia.

The added text says: “Ozempic stimulates insulin release in the presence of elevated blood glucose concentrations. Patients receiving Ozempic in combination with an insulin secretagogue (for instance, sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia.”

This text was already included in both the “Warning and Precautions” and the “Adverse Reactions” sections of the label. The warning also advises, “The risk of hypoglycemia may be lowered by a reduction in the dose of sulfonylurea (or other concomitantly administered insulin secretagogue) or insulin. Inform patients using these concomitant medications of the risk of hypoglycemia and educate them on the signs and symptoms of hypoglycemia.”

Reports of ileus episodes after approval

The second addition concerns a new adverse reaction that was identified during the postmarketing experience.

The FDA has received more than 8,500 reports of gastrointestinal issues among patients prescribed glucagon-like peptide-1 (GLP-1) receptor agonists. Ileus is mentioned in 33 cases, including two deaths, associated with semaglutide. The FDA stopped short of saying there is a direct link between the drug and intestinal blockages.

“Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure,” the FDA stated in its approval of the label update.

The same warning for the risk of intestinal blockages is already listed on the labels for tirzepatide (Mounjaro, Lilly) and semaglutide injection 2.4 mg (Wegovy, Novo Nordisk).

The label change comes after a Louisiana woman filed a lawsuit in August that claims she was “severely injured” after using Mounjaro and Ozempic. She claimed the drug makers failed to disclose risks of vomiting and diarrhea due to inflammation of the stomach lining, as well as the risk of gastroparesis.

*Correction, 10/3/23: An earlier version of this article misstated the semaglutide formulation that received the updates.
