Weekly general vaccination among Medicare beneficiaries aged ≥ 65 year fell by around 80% soon after the national COVID-19 emergency declaration and have recovered only partially and gradually, according to a report by Kai Hong, PhD, and colleagues at the Centers for Disease Control and Prevention, published in the Morbidity and Mortality Weekly Report. “As the pandemic continues,” the investigators stated, “vaccination providers should continue efforts to resolve disruptions in routine adult vaccination.”

The CDC issued guidance recommending postponement of routine adult vaccination in response to the March 13, 2020, COVID-19 national emergency declaration by the U.S. government and also to state and local shelter-in-place orders. Health care facility operations were restricted because of safety concerns around exposure to the SARS-CoV-2 virus. The result was a significant drop in routine medical care including adult vaccinations.

The investigators examined Medicare enrollment and claims data to assess the change in weekly receipt of four routine adult vaccines by Medicare beneficiaries aged ≥65 during the pandemic: (13-valent pneu­mococcal conjugate vaccine [PCV13], 23-valent pneumococ­cal polysaccharide vaccine [PPSV23], tetanus-diphtheria or tetanus-diphtheria-acellular pertussis vaccine [Td/Tdap], and recombinant zoster vaccine [RZV]). The comparison periods were Jan. 6–July 20, 2019, and Jan. 5–July 18, 2020.

Of the Medicare enrollees in the study sample, 85% were White, 7% Black, 2% Asian, 2% Hispanic, and 4% other racial and ethnic groups. For each of the four vaccines overall, weekly rates of vaccination declined sharply after the emergency declaration, compared with corresponding weeks in 2019. In the period prior to the emergency declaration (Jan. 5–March 14, 2020), weekly percentages of Medicare beneficiaries vaccinated with PPSV23, Td/Tdap, and RZV were consistently higher than rates during the same period in 2019.

After the March 13 declaration, while weekly vaccination rates plummeted 25% for PPSV23 and 62% for RZV in the first week, the greatest weekly declines were during April 5-11, 2020, for PCV13, PPSV23, and Td/Tdap, and during April 12-18, 2020, for RZV. The pandemic weekly vaccination rate nadirs revealed declines of 88% for PCV13, 80% for PPSV23, 70% for Td/Tdap, and 89% for RZV.
 

Routine vaccinations increased midyear

Vaccination rates recovered gradually. For the most recently assessed pandemic week (July 12-18, 2020), the rate for PPSV23 was 8% higher than in the corresponding period in 2019. Weekly corresponding rates for other examined vaccines, however, remained much lower than in 2019: 44% lower for RZV, 24% lower for Td/Tdap and 43% lower for PCV13. The CDC Advisory Committee on Immunization Practices voted in June 2019 to stop recommending PCV13 for adults aged ≥65 years and so vaccination with PCV13 among this population declined in 2020, compared with that in 2019.

Another significant drop in the rates of adult vaccinations may have occurred because of the surge in COVID-19 infections in the fall of 2020 and subsequent closures and renewal of lockdown in many localities.
 

Disparities in routine vaccination trends

Dr. Hong and colleagues noted that their findings are consistent with prior reports of declines in pediatric vaccine ordering, administration, and coverage during the pandemic. While the reductions were similar across all racial and ethnic groups, the magnitudes of recovery varied, with vaccination rates lower among racial and ethnic minority adults than among White adults.

Children born to mothers in poor cardiovascular health during pregnancy had an almost eight times higher risk for landing in the poorest cardiovascular health category in early adolescence than children born to mothers who had ideal cardiovascular health during pregnancy.

Doug Brunk/MDedge News

In an observational cohort study that involved 2,302 mother-child dyads, 6.0% of mothers and 2.6% of children were considered to be in the poorest category of cardiovascular health on the basis of specific risk factors.

The children of mothers with any “intermediate” cardiovascular health metrics in pregnancy – for example, being overweight but not obese – were at just more than two times higher risk for poor cardiovascular health in early adolescence.

Although acknowledging the limitations of observational data, Amanda M. Perak, MD, Northwestern University, Chicago, suggested that focusing on whether or not the relationships seen in this study are causal might be throwing the baby out with the bathwater.

“I would suggest that it may not actually matter whether there is causality or correlation here, because if you can identify newborns at birth who have an eight times higher risk for poor cardiovascular health in childhood based on mom’s health during pregnancy, that’s valuable information either way,” said Dr. Perak.

“Even if you don’t know why their risk is elevated, you might be able to target those children for more intensive preventative efforts throughout childhood to help them hold on to their cardiovascular health for longer.”

That said, she thinks it’s possible that the intrauterine environment might actually directly affect offspring health, either through epigenetics modifications to cardiometabolic regulatory genes or possibly through actual organ development. Her group is collecting epigenetic data to study this further.

“We also need to do a study to see if intervening during pregnancy with mothers leads to better cardiovascular health in offspring, and that’s a question we can answer with a clinical trial,” said Dr. Perak.

This study was published on Feb. 16, 2021, in JAMA.
 

Equal footing

“We’ve always talked about cardiovascular health as if everyone is born with ideal cardiovascular health and loses it from there, and I think what this article points out is that not everybody starts on equal footing,” said Stephen R. Daniels, MD, PhD, University of Colorado at Denver, Aurora, who wrote an editorial accompanying the study.

“We need to start upstream, working with mothers before and during pregnancy, but it’s also important to understand, from a pediatric standpoint, that with some of these kids the horse is kind of already out of the barn very early.”

Dr. Daniels is pediatrician in chief and chair of pediatrics at Children’s Hospital Colorado in Aurora.

This study is the first to examine the relevance of maternal gestational cardiovascular health to offspring cardiovascular health and an important first step toward developing new approaches to address the concept of primordial prevention, he said.

“If primary prevention is identifying risk factors and treating them, I think of primordial prevention as preventing the development of those risk factors in the first place,” said Dr. Daniels.

Future trials, he added, should focus on the various mechanistic pathways – biological effects, shared genetics, and lifestyle being the options – to better understand opportunities for intervention.
 

Mother-child pairs

Dr. Perak and colleagues used data from the Hyperglycemia and Adverse Pregnancy Outcomes (HAPO) study and the HAPO Follow-up Study.

Participants were 2,302 mother-child pairs from nine field centers in Barbados, Canada, China, Thailand, United Kingdom, and the United States, and represented a racially and ethnically diverse cohort.

The mean ages were 29.6 years for pregnant mothers and 11.3 years for children. The pregnancies occurred between 2000 and 2006, and the children were examined from 2013 to 2016, when the children were aged 10-14 years.

Using the American Heart Association’s definition of cardiovascular health, the scientists categorized pregnancy health for mothers based on their measures of body mass index, blood pressure, total cholesterol, glucose level, and smoking status at 28 weeks’ gestation. These five metrics of gestational cardiovascular health have been significantly associated with adverse pregnancy outcomes.

They categorized cardiovascular health for offspring at age 10-14 years based on four of these five metrics: body mass index, blood pressure, cholesterol, and glucose.

Only 32.8% of mothers and 42.2% of children had ideal cardiovascular health.

In analyses adjusted for pregnancy and birth outcomes, the associations seen between poor gestational maternal health and offspring cardiovascular health persisted but were attenuated.

Dr. Perak reported receiving grants from the Woman’s Board of Northwestern Memorial Hospital; the Dixon Family; the American Heart Association; and the National Heart, Lung, and Blood Institute. Dr. Daniels reported no conflicts of interest.

The capacity to mount humoral immune responses to COVID-19 vaccinations may be reduced among people who are heavier, older, and male, new findings suggest.

South_agency/Getty Images

The data pertain specifically to the mRNA vaccine, BNT162b2, developed by BioNTech and Pfizer. The study was conducted by Italian researchers and was published Feb. 26 as a preprint.

The study involved 248 health care workers who each received two doses of the vaccine. Of the participants, 99.5% developed a humoral immune response after the second dose. Those responses varied by body mass index (BMI), age, and sex.

“The findings imply that female, lean, and young people have an increased capacity to mount humoral immune responses, compared to male, overweight, and older populations,” Raul Pellini, MD, professor at the IRCCS Regina Elena National Cancer Institute, Rome, and colleagues said.

“To our knowledge, this study is the first to analyze Covid-19 vaccine response in correlation to BMI,” they noted.

“Although further studies are needed, this data may have important implications to the development of vaccination strategies for COVID-19, particularly in obese people,” they wrote. If the data are confirmed by larger studies, “giving obese people an extra dose of the vaccine or a higher dose could be options to be evaluated in this population.”
 

Results contrast with Pfizer trials of vaccine

The BMI finding seemingly contrasts with final data from the phase 3 clinical trial of the vaccine, which were reported in a supplement to an article published Dec. 31, 2020, in the New England Journal of Medicine. In that study, vaccine efficacy did not differ by obesity status.

Akiko Iwasaki, PhD, professor of immunology at the Howard Hughes Medical Institute and an investigator at Yale University, New Haven, Conn., noted that, although the current Italian study showed somewhat lower levels of antibodies in people with obesity, compared with people who did not have obesity, the phase 3 trial found no difference in symptomatic infection rates.

“These results indicate that even with a slightly lower level of antibody induced in obese people, that level was sufficient to protect against symptomatic infection,” Dr. Iwasaki said in an interview.

Indeed, Dr. Pellini and colleagues pointed out that responses to vaccines against influenza, hepatitis B, and rabies are also reduced in those with obesity, compared with lean individuals.

However, they said, it was especially important to study the effectiveness of COVID-19 vaccines in people with obesity, because obesity is a major risk factor for morbidity and mortality in COVID-19.

“The constant state of low-grade inflammation, present in overweight people, can weaken some immune responses, including those launched by T cells, which can directly kill infected cells,” the authors noted.
 

Findings reported in British newspapers

The findings of the Italian study were widely covered in the lay press in the United Kingdom, with headlines such as “Pfizer Vaccine May Be Less Effective in People With Obesity, Says Study” and “Pfizer Vaccine: Overweight People Might Need Bigger Dose, Italian Study Says.” In tabloid newspapers, some headlines were slightly more stigmatizing.

The reports do stress that the Italian research was published as a preprint and has not been peer reviewed, or “is yet to be scrutinized by fellow scientists.”

Most make the point that there were only 26 people with obesity among the 248 persons in the study.

“We always knew that BMI was an enormous predictor of poor immune response to vaccines, so this paper is definitely interesting, although it is based on a rather small preliminary dataset,” Danny Altmann, PhD, a professor of immunology at Imperial College London, told the Guardian.

“It confirms that having a vaccinated population isn’t synonymous with having an immune population, especially in a country with high obesity, and emphasizes the vital need for long-term immune monitoring programs,” he added.
 

Antibody responses differ by BMI, age, and sex

In the Italian study, the participants – 158 women and 90 men – were assigned to receive a priming BNT162b2 vaccine dose with a booster at day 21. Blood and nasopharyngeal swabs were collected at baseline and 7 days after the second vaccine dose.

After the second dose, 99.5% of participants developed a humoral immune response; one person did not respond. None tested positive for SARS-CoV-2.

Titers of SARS-CoV-2–binding antibodies were greater in younger than in older participants. There were statistically significant differences between those aged 37 years and younger (453.5 AU/mL) and those aged 47-56 years (239.8 AU/mL; P = .005), those aged 37 years and younger versus those older than 56 years (453.5 vs 182.4 AU/mL; P < .0001), and those aged 37-47 years versus those older than 56 years (330.9 vs. 182.4 AU/mL; P = .01).

Antibody response was significantly greater for women than for men (338.5 vs. 212.6 AU/mL; P = .001).

Humoral responses were greater in persons of normal-weight BMI (18.5-24.9 kg/m2; 325.8 AU/mL) and those of underweight BMI (<18.5 kg/m2; 455.4 AU/mL), compared with persons with preobesity, defined as BMI of 25-29.9 (222.4 AU/mL), and those with obesity (BMI ≥30; 167.0 AU/mL; P < .0001). This association remained after adjustment for age (P = .003).

“Our data stresses the importance of close vaccination monitoring of obese people, considering the growing list of countries with obesity problems,” the researchers noted.

Hypertension was also associated with lower antibody titers (P = .006), but that lost statistical significance after matching for age (P = .22).

“We strongly believe that our results are extremely encouraging and useful for the scientific community,” Dr. Pellini and colleagues concluded.

The authors disclosed no relevant financial relationships. Dr. Iwasaki is a cofounder of RIGImmune and is a member of its scientific advisory board.

The findings of the Italian study were widely covered in the lay press in the United Kingdom, with headlines such as “Pfizer Vaccine May Be Less Effective in People With Obesity, Says Study” and “Pfizer Vaccine: Overweight People Might Need Bigger Dose, Italian Study Says.” In tabloid newspapers, some headlines were slightly more stigmatizing.

The reports do stress that the Italian research was published as a preprint and has not been peer reviewed, or “is yet to be scrutinized by fellow scientists.”

Most make the point that there were only 26 people with obesity among the 248 persons in the study.

“We always knew that BMI was an enormous predictor of poor immune response to vaccines, so this paper is definitely interesting, although it is based on a rather small preliminary dataset,” Danny Altmann, PhD, a professor of immunology at Imperial College London, told the Guardian.

“It confirms that having a vaccinated population isn’t synonymous with having an immune population, especially in a country with high obesity, and emphasizes the vital need for long-term immune monitoring programs,” he added.
 

Antibody responses differ by BMI, age, and sex

In the Italian study, the participants – 158 women and 90 men – were assigned to receive a priming BNT162b2 vaccine dose with a booster at day 21. Blood and nasopharyngeal swabs were collected at baseline and 7 days after the second vaccine dose.

After the second dose, 99.5% of participants developed a humoral immune response; one person did not respond. None tested positive for SARS-CoV-2.

Titers of SARS-CoV-2–binding antibodies were greater in younger than in older participants. There were statistically significant differences between those aged 37 years and younger (453.5 AU/mL) and those aged 47-56 years (239.8 AU/mL; P = .005), those aged 37 years and younger versus those older than 56 years (453.5 vs 182.4 AU/mL; P < .0001), and those aged 37-47 years versus those older than 56 years (330.9 vs. 182.4 AU/mL; P = .01).

Antibody response was significantly greater for women than for men (338.5 vs. 212.6 AU/mL; P = .001).

Humoral responses were greater in persons of normal-weight BMI (18.5-24.9 kg/m2; 325.8 AU/mL) and those of underweight BMI (<18.5 kg/m2; 455.4 AU/mL), compared with persons with preobesity, defined as BMI of 25-29.9 (222.4 AU/mL), and those with obesity (BMI ≥30; 167.0 AU/mL; P < .0001). This association remained after adjustment for age (P = .003).

“Our data stresses the importance of close vaccination monitoring of obese people, considering the growing list of countries with obesity problems,” the researchers noted.

Hypertension was also associated with lower antibody titers (P = .006), but that lost statistical significance after matching for age (P = .22).

“We strongly believe that our results are extremely encouraging and useful for the scientific community,” Dr. Pellini and colleagues concluded.

The authors disclosed no relevant financial relationships. Dr. Iwasaki is a cofounder of RIGImmune and is a member of its scientific advisory board.

The capacity to mount humoral immune responses to COVID-19 vaccinations may be reduced among people who are heavier, older, and male, new findings suggest.

The data pertain specifically to the mRNA vaccine, BNT162b2, developed by BioNTech and Pfizer. The study was conducted by Italian researchers and was published Feb. 26 as a preprint.

The study involved 248 health care workers who each received two doses of the vaccine. Of the participants, 99.5% developed a humoral immune response after the second dose. Those responses varied by body mass index (BMI), age, and sex.

“The findings imply that female, lean, and young people have an increased capacity to mount humoral immune responses, compared to male, overweight, and older populations,” Raul Pellini, MD, professor at the IRCCS Regina Elena National Cancer Institute, Rome, and colleagues said.

“To our knowledge, this study is the first to analyze Covid-19 vaccine response in correlation to BMI,” they noted.

“Although further studies are needed, this data may have important implications to the development of vaccination strategies for COVID-19, particularly in obese people,” they wrote. If the data are confirmed by larger studies, “giving obese people an extra dose of the vaccine or a higher dose could be options to be evaluated in this population.”
 

Results contrast with Pfizer trials of vaccine

The BMI finding seemingly contrasts with final data from the phase 3 clinical trial of the vaccine, which were reported in a supplement to an article published Dec. 31, 2020, in the New England Journal of Medicine. In that study, vaccine efficacy did not differ by obesity status.

Akiko Iwasaki, PhD, professor of immunology at the Howard Hughes Medical Institute and an investigator at Yale University, New Haven, Conn., noted that, although the current Italian study showed somewhat lower levels of antibodies in people with obesity, compared with people who did not have obesity, the phase 3 trial found no difference in symptomatic infection rates.

“These results indicate that even with a slightly lower level of antibody induced in obese people, that level was sufficient to protect against symptomatic infection,” Dr. Iwasaki said in an interview.

Indeed, Dr. Pellini and colleagues pointed out that responses to vaccines against influenza, hepatitis B, and rabies are also reduced in those with obesity, compared with lean individuals.

However, they said, it was especially important to study the effectiveness of COVID-19 vaccines in people with obesity, because obesity is a major risk factor for morbidity and mortality in COVID-19.

“The constant state of low-grade inflammation, present in overweight people, can weaken some immune responses, including those launched by T cells, which can directly kill infected cells,” the authors noted.

A 16-minute podcast from JAMA: The Journal of the American Medical Association that attempts to discuss structural racism in the U.S. health care system has stirred conversation on social media about the handling and promotion of the episode.

Published on Feb. 23, the episode is hosted on JAMA’s learning platform for doctors and is available for continuing medical education credits.

“No physician is racist, so how can there be structural racism in health care? An explanation of the idea by doctors for doctors in this user-friendly podcast,” JAMA wrote in a Twitter post to promote the episode. That tweet has since been deleted.

“Systemic and interpersonal racism both still exist in our country — they must be rooted out. I do not share the JAMA host’s belief of doing away with the word ‘racism’ will help us be more successful in ending inequities that exists across racial and ethnic lines,” Dr. Katz said. “Further, I believe that we will only produce an equitable society when social and political structures do not continue to produce and perpetuate disparate results based on social race and ethnicity.”

Dr. Katz reiterated that both interpersonal and structural racism continue to exist in the United States, “and it is woefully naive to say that no physician is a racist just because the Civil Rights Act of 1964 forbade it.”

He also recommended JAMA use this controversy “as a learning opportunity for continued dialogue and create another podcast series as an open conversation that invites diverse experts in the field to have an open discussion about structural racism in healthcare.”

The podcast and JAMA’s tweet promoting it were widely criticized on Twitter. In interviews with WebMD, many doctors expressed disbelief that such a respected journal would lend its name to this podcast episode.

B. Bobby Chiong, MD, a radiologist in New York, said although JAMA’s effort to engage with its audience about racism is laudable, it missed the mark.

“I think the backlash comes from how they tried to make a podcast about the subject and somehow made themselves an example of unconscious bias and unfamiliarity with just how embedded in our system is structural racism,” he said. 

Perhaps the podcast’s worst offense was its failure to address the painful history of racial bias in this country that still permeates the medical community, says Tamara Saint-Surin, MD, assistant professor at the University of North Carolina at Chapel Hill.

“For physicians in leadership to have the belief that structural racism does not exist in medicine, they don’t really appreciate what affects their patients and what their patients were dealing with,” Dr. Saint-Surin said in an interview. “It was a very harmful podcast and goes to show we still have so much work to do.”

Along with a flawed premise, she says, the podcast was not nearly long enough to address such a nuanced issue. And Dr. Livingston focused on interpersonal racism rather than structural racism, she said, failing to address widespread problems such as higher rates of asthma among Black populations living in areas with poor air quality.

The number of Black doctors remains low and the lack of representation adds to an environment already rife with racism, according to many medical professionals.

Shirlene Obuobi, MD, an internal medicine doctor in Chicago, said JAMA failed to live up to its own standards by publishing material that lacked research and expertise.

“I can’t submit a clinical trial to JAMA without them combing through methods with a fine-tooth comb,” Dr. Obuobi said. “They didn’t uphold the standards they normally apply to anyone else.”

Both the editor of JAMA and the head of the American Medical Association issued statements criticizing the episode and the tweet that promoted it.

JAMA Editor-in-Chief Howard Bauchner, MD, said, “The language of the tweet, and some portions of the podcast, do not reflect my commitment as editorial leader of JAMA and JAMA Network to call out and discuss the adverse effects of injustice, inequity, and racism in society and medicine as JAMA has done for many years.” He said JAMA will schedule a future podcast to address the concerns raised about the recent episode.

AMA CEO James L. Madara, MD, said, “The AMA’s House of Delegates passed policy stating that racism is structural, systemic, cultural, and interpersonal, and we are deeply disturbed – and angered – by a recent JAMA podcast that questioned the existence of structural racism and the affiliated tweet that promoted the podcast and stated ‘no physician is racist, so how can there be structural racism in health care?’ ”

He continued: “JAMA has editorial independence from AMA, but this tweet and podcast are inconsistent with the policies and views of AMA, and I’m concerned about and acknowledge the harms they have caused. Structural racism in health care and our society exists, and it is incumbent on all of us to fix it.”

One of the biggest conundrums of the COVID-19 pandemic has been the simultaneous panic-hiring of medical professionals in hot spots and significant downsizing of staff across the country. From huge hospital systems to private practices, the stoppage of breast reductions and knee replacements, not to mention the drops in motor vehicle accidents and bar fights, have quieted operating rooms and emergency departments and put doctors’ jobs on the chopping block. A widely cited survey suggests that 21% of doctors have had a work reduction due to COVID-19.

For many American doctors, this is their first extended period of unemployment. Unlike engineers or those with MBAs who might see their fortunes rise and fall with the whims of recessions and boom times, physicians are not exactly accustomed to being laid off. However, doctors were already smarting for years due to falling salaries and decreased autonomy, punctuated by endless clicks on electronic medical records software.

Now, the twin shock of income loss and feeling unwanted in a pandemic – when, you know, medicine might seem especially essential – has doctors resorting to a bizarre array of side gigs, “fun-employment” activities, or outright career overhauls.

Stephanie Eschenbach Morgan, MD, a breast radiologist in North Carolina, trained for 10 years after college before earning a true physician’s salary.

“Being furloughed was awful. Initially, it was only going to be 2 weeks, and then it turned into 2 months with no pay,” she reflected.

Dr. Eschenbach Morgan and her surgeon husband, who lost a full quarter’s salary, had to ask for grace periods on their credit card and mortgage payments because they had paid a large tax bill right before the pandemic began. “We couldn’t get any stimulus help, so that added insult to injury,” she said.

With her time spent waiting in a holding pattern, Dr. Eschenbach Morgan homeschooled her two young children and started putting a home gym together. She went on a home organizing spree, started a garden, and, perhaps most impressively, caught up with 5 years of photo albums.

A bonus she noted: “I didn’t set an alarm for 2 months.”

Shella Farooki, MD, a radiologist in California, was also focused on homeschooling, itself a demanding job, and veered toward retirement. When one of her work contracts furloughed her (“at one point, I made $30K a month for [their business]”), she started saving money at home, teaching the kids, and applied for a Paycheck Protection Program loan. Her husband, a hospitalist, had had his shifts cut. Dr. Farooki tried a radiology artificial intelligence firm but backed out when she was asked to read 9,200 studies for them for $2,000 per month.

Now, she thinks about leaving medicine “every day.”

Some doctors are questioning whether they should be in medicine in the first place. Family medicine physician Jonathan Polak, MD, faced with his own pink slip, turned to pink T-shirts instead. His girlfriend manages an outlet of the teen fashion retailer Justice. Dr. Polak, who finished his residency just 2 years ago, didn’t hesitate to take a $10-an-hour gig as a stock doc, once even finding himself delivering a shelving unit from the shuttering store to a physician fleeing the city for rural New Hampshire to “escape.”

There’s no escape for him – yet. Saddled with “astronomical” student loans, he had considered grocery store work as well. Dr. Polak knows he can’t work part time or go into teaching long term, as he might like.

Even so, he’s doing everything he can to not be in patient care for the long haul – it’s just not what he thought it would be.

“The culture of medicine, bureaucracy, endless paperwork and charting, and threat of litigation sucks a lot of the joy out of it to the point that I don’t see myself doing it forever when imagining myself 5-10 years into it.”

Still, he recently took an 18-month hospital contract that will force him to move to Florida, but he’s also been turning himself into a veritable Renaissance man; composing music, training for an ultramarathon, studying the latest medical findings, roadtripping, and launching a podcast about dog grooming with a master groomer. “We found parallels between medicine and dog grooming,” he says, somewhat convincingly.

Also working the ruff life is Jen Tserng, MD, a former forensic pathologist who landed on news websites in recent years for becoming a professional dogwalker and housesitter without a permanent home. Dr. Tserng knows doctors were restless and unhappy before COVID-19, their thoughts wandering where the grass might be greener.

As her profile grew, she found her inbox gathering messages from disaffected medical minions: students with a fear of failing or staring down residency application season and employed doctors sick of the constant grind. As she recounted those de facto life coach conversations (“What do you really enjoy?” “Do you really like dogs?”) by phone from New York, she said matter-of-factly, “They don’t call because of COVID. They call because they hate their lives.”

Michelle Mudge-Riley, MD, a physician in Texas, has been seeing this shift for some time as well. She recently held a virtual version of her Physicians Helping Physicians conference, where doctors hear from their peers working successfully in fields like pharmaceuticals and real estate investing.

When COVID-19 hit, Dr. Mudge-Riley quickly pivoted to a virtual platform, where the MDs and DOs huddled in breakout rooms having honest chats about their fears and tentative hopes about their new careers.

“There has been increased interest in nonclinical exploration into full- and part-time careers, as well as side hustles, since COVID began,” she said. “Many physicians have had their hours or pay cut, and some have been laid off. Others are furloughed. Some just want out of an environment where they don’t feel safe.”

An ear, nose, and throat surgeon, Maansi Doshi, MD, from central California, didn’t feel safe – so she left. She had returned from India sick with a mystery virus right as the pandemic began (she said her COVID-19 tests were all negative) and was waiting to get well enough to go back to her private practice job. However, she said she clashed with Trump-supporting colleagues she feared might not be taking the pandemic seriously enough.

Finally getting over a relapse of her mystery virus, Dr. Doshi emailed her resignation in May. Her husband, family practice doctor Mark Mangiapane, MD, gave his job notice weeks later in solidarity because he worked in the same building. Together, they have embraced gardening, a Peloton splurge, and learning business skills to open private practices – solo primary care for him; ENT with a focus on her favorite surgery, rhinoplasty, for her.

Dr. Mangiapane had considered editing medical brochures and also tried to apply for a job as a county public health officer in rural California, but he received his own shock when he learned the county intended to open schools in the midst of the pandemic despite advisement to the contrary by the former health officer.

He retreated from job listings altogether after hearing his would-be peers were getting death threats – targeting their children.

Both doctors felt COVID-19 pushed them beyond their comfort zones. “If COVID hadn’t happened, I would be working. ... Be ‘owned.’ In a weird way, COVID made me more independent and take a risk with my career.”

Obstetrician Kwandaa Roberts, MD, certainly did; she took a budding interest in decorating dollhouses straight to Instagram and national news fame, and she is now a TV-show expert on “Sell This House.”

Like Dr. Doshi and Dr. Mangiapane, Dr. Polak wants to be more in control of his future – even if selling T-shirts at a mall means a certain loss of status along the way.

“Aside from my passion to learn and to have that connection with people, I went into medicine ... because of the job security I thought existed,” he said. “I would say that my getting furloughed has changed my view of the United States in a dramatic way. I do not feel as confident in the U.S. economy and general way of life as I did a year ago. And I am taking a number of steps to put myself in a more fluid, adaptable position in case another crisis like this occurs or if the current state of things worsens.”

Some doctors are questioning whether they should be in medicine in the first place. Family medicine physician Jonathan Polak, MD, faced with his own pink slip, turned to pink T-shirts instead. His girlfriend manages an outlet of the teen fashion retailer Justice. Dr. Polak, who finished his residency just 2 years ago, didn’t hesitate to take a $10-an-hour gig as a stock doc, once even finding himself delivering a shelving unit from the shuttering store to a physician fleeing the city for rural New Hampshire to “escape.”

There’s no escape for him – yet. Saddled with “astronomical” student loans, he had considered grocery store work as well. Dr. Polak knows he can’t work part time or go into teaching long term, as he might like.

Even so, he’s doing everything he can to not be in patient care for the long haul – it’s just not what he thought it would be.

“The culture of medicine, bureaucracy, endless paperwork and charting, and threat of litigation sucks a lot of the joy out of it to the point that I don’t see myself doing it forever when imagining myself 5-10 years into it.”

Still, he recently took an 18-month hospital contract that will force him to move to Florida, but he’s also been turning himself into a veritable Renaissance man; composing music, training for an ultramarathon, studying the latest medical findings, roadtripping, and launching a podcast about dog grooming with a master groomer. “We found parallels between medicine and dog grooming,” he says, somewhat convincingly.

Also working the ruff life is Jen Tserng, MD, a former forensic pathologist who landed on news websites in recent years for becoming a professional dogwalker and housesitter without a permanent home. Dr. Tserng knows doctors were restless and unhappy before COVID-19, their thoughts wandering where the grass might be greener.

As her profile grew, she found her inbox gathering messages from disaffected medical minions: students with a fear of failing or staring down residency application season and employed doctors sick of the constant grind. As she recounted those de facto life coach conversations (“What do you really enjoy?” “Do you really like dogs?”) by phone from New York, she said matter-of-factly, “They don’t call because of COVID. They call because they hate their lives.”

Michelle Mudge-Riley, MD, a physician in Texas, has been seeing this shift for some time as well. She recently held a virtual version of her Physicians Helping Physicians conference, where doctors hear from their peers working successfully in fields like pharmaceuticals and real estate investing.

When COVID-19 hit, Dr. Mudge-Riley quickly pivoted to a virtual platform, where the MDs and DOs huddled in breakout rooms having honest chats about their fears and tentative hopes about their new careers.

“There has been increased interest in nonclinical exploration into full- and part-time careers, as well as side hustles, since COVID began,” she said. “Many physicians have had their hours or pay cut, and some have been laid off. Others are furloughed. Some just want out of an environment where they don’t feel safe.”

An ear, nose, and throat surgeon, Maansi Doshi, MD, from central California, didn’t feel safe – so she left. She had returned from India sick with a mystery virus right as the pandemic began (she said her COVID-19 tests were all negative) and was waiting to get well enough to go back to her private practice job. However, she said she clashed with Trump-supporting colleagues she feared might not be taking the pandemic seriously enough.

Finally getting over a relapse of her mystery virus, Dr. Doshi emailed her resignation in May. Her husband, family practice doctor Mark Mangiapane, MD, gave his job notice weeks later in solidarity because he worked in the same building. Together, they have embraced gardening, a Peloton splurge, and learning business skills to open private practices – solo primary care for him; ENT with a focus on her favorite surgery, rhinoplasty, for her.

Dr. Mangiapane had considered editing medical brochures and also tried to apply for a job as a county public health officer in rural California, but he received his own shock when he learned the county intended to open schools in the midst of the pandemic despite advisement to the contrary by the former health officer.

He retreated from job listings altogether after hearing his would-be peers were getting death threats – targeting their children.

Both doctors felt COVID-19 pushed them beyond their comfort zones. “If COVID hadn’t happened, I would be working. ... Be ‘owned.’ In a weird way, COVID made me more independent and take a risk with my career.”

Obstetrician Kwandaa Roberts, MD, certainly did; she took a budding interest in decorating dollhouses straight to Instagram and national news fame, and she is now a TV-show expert on “Sell This House.”

Like Dr. Doshi and Dr. Mangiapane, Dr. Polak wants to be more in control of his future – even if selling T-shirts at a mall means a certain loss of status along the way.

“Aside from my passion to learn and to have that connection with people, I went into medicine ... because of the job security I thought existed,” he said. “I would say that my getting furloughed has changed my view of the United States in a dramatic way. I do not feel as confident in the U.S. economy and general way of life as I did a year ago. And I am taking a number of steps to put myself in a more fluid, adaptable position in case another crisis like this occurs or if the current state of things worsens.”

One of the biggest conundrums of the COVID-19 pandemic has been the simultaneous panic-hiring of medical professionals in hot spots and significant downsizing of staff across the country. From huge hospital systems to private practices, the stoppage of breast reductions and knee replacements, not to mention the drops in motor vehicle accidents and bar fights, have quieted operating rooms and emergency departments and put doctors’ jobs on the chopping block. A widely cited survey suggests that 21% of doctors have had a work reduction due to COVID-19.

For many American doctors, this is their first extended period of unemployment. Unlike engineers or those with MBAs who might see their fortunes rise and fall with the whims of recessions and boom times, physicians are not exactly accustomed to being laid off. However, doctors were already smarting for years due to falling salaries and decreased autonomy, punctuated by endless clicks on electronic medical records software.

Now, the twin shock of income loss and feeling unwanted in a pandemic – when, you know, medicine might seem especially essential – has doctors resorting to a bizarre array of side gigs, “fun-employment” activities, or outright career overhauls.

Stephanie Eschenbach Morgan, MD, a breast radiologist in North Carolina, trained for 10 years after college before earning a true physician’s salary.

“Being furloughed was awful. Initially, it was only going to be 2 weeks, and then it turned into 2 months with no pay,” she reflected.

Dr. Eschenbach Morgan and her surgeon husband, who lost a full quarter’s salary, had to ask for grace periods on their credit card and mortgage payments because they had paid a large tax bill right before the pandemic began. “We couldn’t get any stimulus help, so that added insult to injury,” she said.

With her time spent waiting in a holding pattern, Dr. Eschenbach Morgan homeschooled her two young children and started putting a home gym together. She went on a home organizing spree, started a garden, and, perhaps most impressively, caught up with 5 years of photo albums.

A bonus she noted: “I didn’t set an alarm for 2 months.”

Shella Farooki, MD, a radiologist in California, was also focused on homeschooling, itself a demanding job, and veered toward retirement. When one of her work contracts furloughed her (“at one point, I made $30K a month for [their business]”), she started saving money at home, teaching the kids, and applied for a Paycheck Protection Program loan. Her husband, a hospitalist, had had his shifts cut. Dr. Farooki tried a radiology artificial intelligence firm but backed out when she was asked to read 9,200 studies for them for $2,000 per month.

Now, she thinks about leaving medicine “every day.”

Exercise training – but not testosterone therapy – improved vascular health in aging men with widening midsections and low to normal testosterone, new research suggests.

“Previous studies have suggested that men with higher levels of testosterone, who were more physically active, might have better health outcomes,” Bu Beng Yeap, MBBS, PhD, University of Western Australia, Perth, said in an interview. “We formulated the hypothesis that the combination of testosterone treatment and exercise training would improve the health of arteries more than either alone.”

To test this hypothesis, the investigators randomly assigned 80 men, aged 50-70 years, to 12 weeks of 5% testosterone cream 2 mL applied daily or placebo plus a supervised exercise program that included machine-based resistance and aerobic (cycling) exercises two to three times a week or no additional exercise.

The men (mean age, 59 years) had low-normal testosterone (6-14 nmol/L), a waist circumference of at least 95 cm (37.4 inches), and no known cardiovascular disease (CVD), type 1 diabetes, or other clinically significant illnesses. Current smokers and men on testosterone or medications that would alter testosterone levels were also excluded.

High-resolution ultrasound of the brachial artery was used to assess flow-mediated dilation (FMD) and sublingual glyceryl trinitrate (GTN) responses. FMD has been shown to be predictive of CVD risk, with a 1% increase in FMD associated with a 9%-13% decrease in future CVD events.

Based on participants’ daily dairies, testosterone adherence was 97.6%. Exercise adherence was 96.5% for twice-weekly attendance and 80.0% for thrice-weekly attendance, with no between-group differences.

As reported Feb. 22, 2021, in Hypertension, testosterone levels increased, on average, 3.0 nmol/L in both testosterone groups by week 12 (P = .003). In all, 62% of these men had levels of the hormone exceeding 14 nmol/L, compared with 29% of those receiving placebo.

Testosterone levels improved with exercise training plus placebo by 0.9 nmol/L, but fell with no exercise and placebo by 0.9 nmol/L.

In terms of vascular function, exercise training increased FMD when expressed as both the delta change (mm; P = .004) and relative rise from baseline diameter (%; P = .033).

There was no effect of exercise on GTN%, which is generally in line with exercise literature indicating that shear-mediated adaptations in response to episodic exercise occur largely in endothelial cells, the authors noted.

Testosterone did not affect any measures of FMD nor was there an effect on GTN response, despite previous evidence that lower testosterone doses might enhance smooth muscle function.

“Our main finding was that testosterone – at this dose over this duration of treatment – did not have a beneficial effect on artery health, nor did it enhance the effect of exercise,” said Dr. Yeap, who is also president of the Endocrine Society of Australia. “For middle-aged and older men wanting to improve the health of their arteries, exercise is better than testosterone!”

Shalender Bhasin, MBBS, director of research programs in men’s health, aging, and metabolism at Brigham and Women’s Hospital and professor of medicine at Harvard Medical School, both in Boston, said the study is interesting from a mechanistic perspective and adds to the overall body of evidence on how testosterone affects performance, but was narrowly focused.

“They looked at very specific markers and what they’re showing is that this is not the mechanism by which testosterone improves performance,” he said. “That may be so, but it doesn’t negate the finding that testosterone improves endurance and has other vascular effects: it increases capillarity, increases blood flow to the tissues, and improves myocardial function.”

Although well done, the study doesn’t get at the larger question of whether testosterone increases cardiovascular risk, observed Dr. Bhasin. “None of the randomized studies have been large enough or long enough to determine the effect on cardiovascular events rates. There’s a lot of argument on both sides but we need some data to address that.”

The 6,000-patient TRAVERSE trial is specifically looking at long-term major cardiovascular events with topical testosterone, compared with placebo, in hypogonadal men aged 45-80 years age who have evidence of or are at increased risk for CVD. The study, which is set to be completed in April 2022, should also provide information on fracture risk in these men, said Dr. Bhasin, one of the trial’s principal investigators and lead author of the Endocrine Society’s 2018 clinical practice guideline on testosterone therapy for hypogonadism in men.

William Evans, MD, adjunct professor of human nutrition, University of California, Berkley, said in an interview that the positive effects of testosterone occur at much lower doses in men and women who are hypogonadal but, in this particular population, exercise is the key and the major recommendation.

“Testosterone has been overprescribed and overadvertised for essentially a lifetime of sedentary living, and it’s advertised as a way to get all that back without having to work for it,” he said. “Exercise has a profound and positive effect on control of blood pressure, function, and strength, and testosterone may only affect in people who are sick, people who have really low levels.”

The study was funded by the Heart Foundation of Australia. Lawley Pharmaceuticals provided the study medication and placebo. Dr. Yeap has received speaker honoraria and conference support from Bayer, Eli Lilly, and Besins Healthcare; research support from Bayer, Lily, and Lawley; and served as an adviser for Lily, Besins Healthcare, Ferring, and Lawley. Dr. Shalender reports consultation or advisement for GTx, Pfizer, and TAP; grant or other research support from Solvay and GlaxoSmithKline; and honoraria from Solvay and Auxilium. Dr. Evans reported having no relevant conflicts of interest.

In patients with acute ischemic stroke, the use of thrombolysis in the late window of 4.5-9 hours after symptom onset was not associated with an increase in clot migration that would cause reduced clot accessibility to endovascular therapy, a new analysis from the EXTEND trial shows.

“There was no significant difference in the incidence of clot migration leading to clot inaccessibility in patients who received placebo or (intravenous) thrombolysis,” the authors report.

“Our results found no convincing evidence against the use of bridging thrombolysis before endovascular therapy in patients with acute ischemic stroke who present outside the 4.5-hour window,” they conclude.

“This information is important because it provides some comfort for neurointerventionists that IV thrombolysis does not unduly increase the risk of clot migration,” senior author, Bernard Yan, DMedSci, FRACP, told this news organization.

The study was published online in Stroke on Feb. 16.

The Australian researchers explain that endovascular thrombectomy is the standard of care in patients presenting with acute ischemic stroke caused by large-vessel occlusion, and current treatment guidelines recommend bridging thrombolysis for all patients receiving thrombectomy within the 4.5-hour time window.

While thrombectomy is also recommended in selected patients up to 24 hours after onset of symptoms, it remains unclear whether thrombolysis pretreatment should be administered in this setting.

One of the issues that might affect use of thrombolysis is distal clot migration. As proximal clot location is a crucial factor determining suitability for endovascular clot retrieval, distal migration may prevent successful thrombectomy, they note.   

“Clot migration can happen any time and makes life more difficult for the neurointerventionist who performs the endovascular clot retrieval,” added Dr. Yan, who is a neurologist and neurointerventionist at the Royal Melbourne Hospital, Australia.

In the current paper, the researchers report a retrospective analysis of data from the EXTEND trial of late thrombolysis, defined as 4.5-9 hours after symptom onset, to investigate the association between thrombolysis and clot migration leading to clot irretrievability.

The analysis included a total of 220 patients (109 patients in the placebo group and 111 in the thrombolysis group).

Results showed that retrievable clot was seen on baseline imaging in 69% of patients in the placebo group and 61% in the thrombolysis group. Clot resolution occurred in 28% of patients in the placebo group and 50% in the thrombolysis group. 

No significant difference was observed in the incidence of clot migration leading to inaccessibility between groups. Clot migration from a retrievable to nonretrievable location occurred in 19% of the placebo group and 14% of the thrombolysis group, with an odds ratio for clot migration in the thrombolysis group of 0.70 (95% confidence interval, 0.35-1.44). This outcome was consistent across subgroups.

The researchers note that, to their knowledge, this is the first randomized controlled study to assess the effect of thrombolysis on clot migration and accessibility in an extended time window.

They acknowledge that a limitation of this study is that they only assessed clot migration from a retrievable to a nonretrievable location; therefore, the true frequency of any clot migration occurring was likely to be higher, and this could explain why other reports have found higher odds ratios of clot migration.

But they point out that they chose to limit their analysis in this way specifically to guide decision-making regarding bridging thrombolysis incorporating endovascular therapy in the extended time window.

“The findings of this study are highly relevant in the current clinical environment, where there are multiple ongoing trials looking at removing thrombolysis pretreatment within the 4.5-hour time window in thrombectomy patients,” the authors write.  

“We have demonstrated that thrombolysis in the 4.5- to 9-hour window is not associated with reduced clot accessibility, and this information will be useful in future trial designs incorporating this extended time window,” they add.

Commenting on the study for this news organization, Michael Hill, MD, University of Calgary (Alta.), said: “Thrombus migration does happen and is likely part of the natural history of ischemic stroke, which may be influenced by therapeutics such as thrombolysis. This paper’s top-line result is that thrombus migration occurs in both treated and untreated groups – and therefore that this is really an observation of natural history.”

Dr. Hill says that, at present, patients should be treated with thrombolysis before endovascular therapy if they are eligible, and these results do not change that recommendation. 

“The results of the ongoing trials comparing direct thrombectomy with thrombolysis plus thrombectomy will help to understand the potential clinical outcome relevance of this phenomenon,” he added.

The EXTEND trial was supported by grants from the Australian National Health and Medical Research Council of Australia and the Commonwealth Scientific and Industrial Research Organization Flagship Program. Dr. Yan reported no relevant financial relationships.

In patients with acute ischemic stroke, the use of thrombolysis in the late window of 4.5-9 hours after symptom onset was not associated with an increase in clot migration that would cause reduced clot accessibility to endovascular therapy, a new analysis from the EXTEND trial shows.

“There was no significant difference in the incidence of clot migration leading to clot inaccessibility in patients who received placebo or (intravenous) thrombolysis,” the authors report.

“Our results found no convincing evidence against the use of bridging thrombolysis before endovascular therapy in patients with acute ischemic stroke who present outside the 4.5-hour window,” they conclude.

“This information is important because it provides some comfort for neurointerventionists that IV thrombolysis does not unduly increase the risk of clot migration,” senior author, Bernard Yan, DMedSci, FRACP, told this news organization.

The study was published online in Stroke on Feb. 16.

The Australian researchers explain that endovascular thrombectomy is the standard of care in patients presenting with acute ischemic stroke caused by large-vessel occlusion, and current treatment guidelines recommend bridging thrombolysis for all patients receiving thrombectomy within the 4.5-hour time window.

While thrombectomy is also recommended in selected patients up to 24 hours after onset of symptoms, it remains unclear whether thrombolysis pretreatment should be administered in this setting.

One of the issues that might affect use of thrombolysis is distal clot migration. As proximal clot location is a crucial factor determining suitability for endovascular clot retrieval, distal migration may prevent successful thrombectomy, they note.   

“Clot migration can happen any time and makes life more difficult for the neurointerventionist who performs the endovascular clot retrieval,” added Dr. Yan, who is a neurologist and neurointerventionist at the Royal Melbourne Hospital, Australia.

In the current paper, the researchers report a retrospective analysis of data from the EXTEND trial of late thrombolysis, defined as 4.5-9 hours after symptom onset, to investigate the association between thrombolysis and clot migration leading to clot irretrievability.

The analysis included a total of 220 patients (109 patients in the placebo group and 111 in the thrombolysis group).

Results showed that retrievable clot was seen on baseline imaging in 69% of patients in the placebo group and 61% in the thrombolysis group. Clot resolution occurred in 28% of patients in the placebo group and 50% in the thrombolysis group. 

No significant difference was observed in the incidence of clot migration leading to inaccessibility between groups. Clot migration from a retrievable to nonretrievable location occurred in 19% of the placebo group and 14% of the thrombolysis group, with an odds ratio for clot migration in the thrombolysis group of 0.70 (95% confidence interval, 0.35-1.44). This outcome was consistent across subgroups.

The researchers note that, to their knowledge, this is the first randomized controlled study to assess the effect of thrombolysis on clot migration and accessibility in an extended time window.

They acknowledge that a limitation of this study is that they only assessed clot migration from a retrievable to a nonretrievable location; therefore, the true frequency of any clot migration occurring was likely to be higher, and this could explain why other reports have found higher odds ratios of clot migration.

People who mostly ate foods with a low glycemic index had a lower likelihood of premature death and major cardiovascular disease (CVD) events, compared with those whose diet included more “poor-quality” food with a high glycemic index.

The results from the global PURE study of nearly 120,000 people provide evidence that helps cement glycemic index as a key measure of dietary health.

This new analysis from PURE (Prospective Urban and Rural Epidemiological Study) – a massive prospective epidemiologic study – shows people with a diet in the highest quintile of glycemic index had a significant 25% higher rate of combined total deaths and major CVD events during a median follow-up of nearly 10 years, compared with those with a diet in the lowest glycemic index quintile, in the report published online on Feb. 24, 2021, in the New England Journal of Medicine.

David J.A. Jenkins, MD, PhD, DSc, lead author, said people do not necessarily need to closely track the glycemic index of what they eat to follow the guidance that lower is better.

The link between lower glycemic load and fewer CVD events was even stronger among people with an established history of CVD at study entry. In this subset, which included 9% of the total cohort, people in the highest quintile for glycemic index consumption had a 51% higher rate of the composite primary endpoint, compared with those in the lowest quintile, in an analysis that adjusted for several potential confounders.

A simple but accurate and effective public health message is to follow existing dietary recommendations to eat better-quality food – more unprocessed fruits, vegetables, legumes, and whole grains – Dr. Jenkins advised. Those who prefer a more detailed approach could use the comprehensive glycemic index tables compiled by researchers at the University of Sydney.
 

‘All carbohydrates are not the same’

“What we’re saying is that all carbohydrates are not the same. Some seem to increase the risk for CVD, and others seem protective. This is not new, but worth restating in an era of low-carb and no-carb diets,” said Dr. Jenkins.

Low-glycemic-index foods are generally unprocessed foods in their native state, including fruits, vegetables, legumes, and unrefined whole grains. High-glycemic-index foods contain processed and refined carbohydrates that deliver jolts of glucose soon after eating, as the sugar in these carbohydrates quickly moves from the gut to the bloodstream.

An association between a diet with a lower glycemic index and better outcomes had appeared in prior reports from other studies, but not as unambiguously as in the new data from PURE, likely because of fewer study participants in previous studies.

Another feature of PURE that adds to the generalizability of the findings is the diversity of adults included in the study, from 20 countries on five continents.

“This clinches it,” Dr. Jenkins declared in an interview.
 

New PURE data tip the evidence balance

The NEJM article includes a new meta-analysis that adds the PURE findings to data from two large prior reports that were each less conclusive. The new calculation with the PURE numbers helps establish a clearer association between a diet with a higher glycemic index and the endpoint of CVD death, showing an overall 26% increase in the outcome.

The PURE data are especially informative because the investigators collected additional information on a range of potential confounders they incorporated into their analyses.

“We were able to include a lot of documentation on many potential confounders. That’s a strength of our data,” noted Dr. Jenkins, a professor of nutritional science and medicine at the University of Toronto.

Higher BMI associated with greater glycemic index effect

Another important analysis in the new report calculated the impact of a higher glycemic index diet among people with a body mass index (BMI) of less than 25 kg/m2 as well as higher BMIs.

Among people in the lower BMI subgroup, greater intake of high-glycemic-index foods showed slightly more incident primary outcome events. In contrast, people with a BMI of 25 or greater showed a steady increment in primary outcome events as the glycemic index of their diet increased.

People with higher BMIs in the quartile that ate the greatest amount of high-glycemic =-index foods had a significant 38% higher rate of primary outcome events, compared with people with similar BMIs in the lowest quartile for high-glycemic-index intake.

However, the study showed no impact on the primary association of high glycemic index and increased adverse outcomes by exercise habits, smoking, use of blood pressure medications, or use of statins. 

The new report complements a separate analysis from PURE published just a few weeks earlier in the BMJ that established a significant association between increased consumption of whole grains and fewer CVD events, compared with people who had more refined grains in their diet, as reported by this news organization.

This prior report on whole versus refined grains, which Dr. Jenkins coauthored, looked at carbohydrate quality using a two-pronged approach, while glycemic index is a continuous variable that provides more nuance and takes into account carbohydrates from sources other than grains, Dr. Jenkins said.

PURE enrolled roughly 225,000 people aged 35-70 years at entry. The glycemic index analysis focused on 119,575 people who had data available for the primary outcome. During a median follow-up of 9.5 years, these people had 14,075 primary outcome events, including 8,780 deaths.

Analyses that looked at the individual outcomes that comprised the composite endpoint showed significant associations between a high-glycemic-index diet and total mortality, CVD death, non-CVD death, and stroke, but showed no significant link with myocardial infarction or heart failure. These findings are consistent with prior results of other studies that showed a stronger link between stroke and a high glycemic index diet, compared with other nonfatal CVD events.

Dr. Jenkins suggested that the significant excess of non-CVD deaths linked with a high-glycemic-index diet may stem from the impact of this type of diet on cancer-associated mortality.

PURE received partial funding through unrestricted grants from several drug companies. Dr. Jenkins has reported receiving gifts from several food-related trade associations and food companies, as well as research grants from two legume-oriented trade associations.

A study of post–COVID-19 patients in the United Kingdom who developed severe lung inflammation after they left the hospital may provide greater clarity on which patients are most likely to have persistent lung dysfunction.

In addition to pinpointing those most at risk, the findings showed that conventional corticosteroid treatment is highly effective in improving lung function and reducing symptoms.

Researchers from Guy’s and St. Thomas’ National Health Foundation Trust in London reported that a small percentage of patients – 4.8%, or 35 of 837 patients in the study – had severe persistent interstitial lung disease (ILD), mostly organizing pneumonia, 4 weeks after discharge. Of these patients, 30 received steroid treatment, all of whom showed improvement in lung function.

Lead author Katherine Jane Myall, MRCP, and colleagues wrote that the most common radiologic finding in acute COVID-19 is bilateral ground-glass opacification, and findings of organizing pneumonia are common. However, no reports exist of the role of inflammatory infiltrates during recovery from COVID-19 or of the effectiveness of treatments for persistent ILD. “The long-term respiratory morbidity remains unclear,” Dr. Myall and colleagues wrote.

The study findings are significant because they quantify the degree of lung disease that patients have after COVID-19, said Sachin Gupta, MD, FCCP, a pulmonologist and critical care specialist at Alameda Health System in Oakland, Calif. He added that the disease course and presentation followed the pattern of organizing pneumonia in some patients, and traditional corticosteroid therapy seemed to resolve symptoms and improve lung function.

“This is a really important piece to get out there because it describes what a lot of us are worried about in patients with post-COVID lung disease and about what type of lung disease they have. It offers a potential treatment,” he said.

Dr. Myall and colleagues noted that even a “relatively small proportion” of patients with persistent, severe ILD – as reported in this study – pose “a significant disease burden.” They added: “Prompt therapy may avoid potentially permanent fibrosis and functional impairment.”

The single-center, prospective, observational study followed discharged patients with telephone calls 4 weeks after discharge to determine their status. At that point, 39% of the study cohort (n = 325) reported ongoing symptoms.

The patients had outpatient examinations at 6 weeks post discharge, at which time 42.9% (n = 138) had no signs or symptoms of persistent disease; 33.8% (n = 110) had symptoms but no radiologic findings and received referrals to other departments; and 24% (n = 77) were referred to the post-COVID lung disease multidisciplinary team. A total of 59 were diagnosed with persistent post-COVID interstitial change, 35 of whom had organizing pneumonia, hence the rationale for using steroids in this group, Dr. Myall and colleagues stated.

The 30 patients treated with corticosteroids received a maximum initial dose of 0.5 mg/kg prednisolone, which was rapidly weaned over 3 weeks. Some patients received lower doses depending on their comorbidities.

Treatment resulted in an average relative increase in transfer factor of 31.6% (P < .001) and forced vital capacity of 9.6% (P = .014), along with significant improvement in symptoms and x-ray signs.

The study identified some key characteristics of the patients who had persistent post–COVID-19 inflammatory ILD. They were mostly male (71.5%) and overweight with an average body mass index of 28.3, but only 26% were obese. Most had at least one comorbidity, with the most common being diabetes and asthma (22.9%). Their average hospital stay was 16.9 days, 82.9% required oxygen, 55% were in the ICU, and 46% needed invasive mechanical ventilation.

The patients most vulnerable to ILD and organizing pneumonia were the “sicker” of the whole cohort, Dr. Gupta said. “In one sense, it’s reassuring that this is not just happening in anyone; this is happening in patients who had the worst course and were hospitalized in the ICU for the most part.”

The study shows that identifying these patients early on and initiating steroid therapy could avoid persistent lung injury and scarring, Dr. Gupta said.

The London researchers noted that theirs wasn’t a radiologic study, so CT scans weren’t formally scored before and after treatment. They also acknowledged vagueness about imaging and clinical findings representing “nothing other than slow ongoing recovery.”

Patients with post–COVID-19 ILD will require ongoing follow-up to better understand the disease course, Dr. Myall and colleagues stated, although they predicted organizing pneumonia is unlikely to recur once it resolves.

Dr. Myall and coauthors had no relevant relationships to disclose. Dr. Gupta disclosed he is also an employee and shareholder at Genentech.

A study of post–COVID-19 patients in the United Kingdom who developed severe lung inflammation after they left the hospital may provide greater clarity on which patients are most likely to have persistent lung dysfunction.

Of these patients, 30 received steroid treatment, all of whom showed improvement in lung function.

Lead author Katherine Jane Myall, MRCP, and colleagues wrote that the most common radiologic finding in acute COVID-19 is bilateral ground-glass opacification, and findings of organizing pneumonia are common. However, no reports exist of the role of inflammatory infiltrates during recovery from COVID-19 or of the effectiveness of treatments for persistent ILD. “The long-term respiratory morbidity remains unclear,” Dr. Myall and colleagues wrote.

The study findings are significant because they quantify the degree of lung disease that patients have after COVID-19, said Sachin Gupta, MD, FCCP, a pulmonologist and critical care specialist at Alameda Health System in Oakland, Calif. He added that the disease course and presentation followed the pattern of organizing pneumonia in some patients, and traditional corticosteroid therapy seemed to resolve symptoms and improve lung function.

“This is a really important piece to get out there because it describes what a lot of us are worried about in patients with post-COVID lung disease and about what type of lung disease they have. It offers a potential treatment,” he said.

Dr. Myall and colleagues noted that even a “relatively small proportion” of patients with persistent, severe ILD – as reported in this study – pose “a significant disease burden.” They added: “Prompt therapy may avoid potentially permanent fibrosis and functional impairment.”

The single-center, prospective, observational study followed discharged patients with telephone calls 4 weeks after discharge to determine their status. At that point, 39% of the study cohort (n = 325) reported ongoing symptoms.

The patients had outpatient examinations at 6 weeks post discharge, at which time 42.9% (n = 138) had no signs or symptoms of persistent disease; 33.8% (n = 110) had symptoms but no radiologic findings and received referrals to other departments; and 24% (n = 77) were referred to the post-COVID lung disease multidisciplinary team. A total of 59 were diagnosed with persistent post-COVID interstitial change, 35 of whom had organizing pneumonia, hence the rationale for using steroids in this group, Dr. Myall and colleagues stated.

The 30 patients treated with corticosteroids received a maximum initial dose of 0.5 mg/kg prednisolone, which was rapidly weaned over 3 weeks. Some patients received lower doses depending on their comorbidities.

Treatment resulted in an average relative increase in transfer factor of 31.6% (P < .001) and forced vital capacity of 9.6% (P = .014), along with significant improvement in symptoms and x-ray signs.

The study identified some key characteristics of the patients who had persistent post–COVID-19 inflammatory ILD. They were mostly male (71.5%) and overweight with an average body mass index of 28.3, but only 26% were obese. Most had at least one comorbidity, with the most common being diabetes and asthma (22.9%). Their average hospital stay was 16.9 days, 82.9% required oxygen, 55% were in the ICU, and 46% needed invasive mechanical ventilation.

The patients most vulnerable to ILD and organizing pneumonia were the “sicker” of the whole cohort, Dr. Gupta said. “In one sense, it’s reassuring that this is not just happening in anyone; this is happening in patients who had the worst course and were hospitalized in the ICU for the most part.”

The study shows that identifying these patients early on and initiating steroid therapy could avoid persistent lung injury and scarring, Dr. Gupta said.

The London researchers noted that theirs wasn’t a radiologic study, so CT scans weren’t formally scored before and after treatment. They also acknowledged vagueness about imaging and clinical findings representing “nothing other than slow ongoing recovery.”

Patients with post–COVID-19 ILD will require ongoing follow-up to better understand the disease course, Dr. Myall and colleagues stated, although they predicted organizing pneumonia is unlikely to recur once it resolves.

Dr. Myall and coauthors had no relevant relationships to disclose. Dr. Gupta disclosed he is also an employee and shareholder at Genentech.

A study of post–COVID-19 patients in the United Kingdom who developed severe lung inflammation after they left the hospital may provide greater clarity on which patients are most likely to have persistent lung dysfunction.

New guidelines from the American Society of Hematology “strongly recommend” using no thromboprophylaxis over using parenteral thromboprophylaxis in ambulatory patients receiving cancer chemotherapy who have low venous thromboembolism (VTE) risk, and using no thromboprophylaxis over oral thromboprophylaxis with vitamin K antagonists in those at any VTE risk level.

The evidence-based guidelines for the prevention and treatment of VTE in patient with cancer, published online in Blood Advances, also include a “conditional recommendation” for using either thromboprophylaxis with the direct oral anticoagulants (DOACs) apixaban or rivaroxaban or using no thromboprophylaxis in ambulatory patients with intermediate risk and using the DOACs over no thromboprophylaxis in those with high VTE risk.

The purpose of the guidelines, which also address VTE prophylaxis in hospitalized patients with cancer and the use of anticoagulation for VTE treatment in patients with cancer, is to provide clinical decision support for shared decision-making by patients and clinicians, Gary H. Lyman, MD, of Fred Hutchinson Cancer Research Center, Seattle and Marc Carrier, MD, of the University of Ottawa, and their colleagues from the multidisciplinary guidelines panel explained.

“The recommendations take into consideration the strength of the evidence, risks of mortality, VTE, and bleeding, as well as quality of life, acceptability, and cost considerations,” they wrote, noting that VTE is a common complication in patients with cancer, who are at markedly increased risk for morbidity and mortality from VTE.
 

Levels of evidence

The panel members relied on updated and original systematic evidence reviews. Conditional recommendations, as opposed to strong recommendations, are defined by the panel as “suggestions,” and all 33 recommendations that make up the guidelines include a statement on the strength of the relevant evidence.

For example, the thromboprophylaxis recommendations for low, intermediate, and high VTE risk are made based on “moderate certainty in the evidence of effects,” and the recommendation for no thromboprophylaxis over oral thromboprophylaxis with vitamin K antagonists is a strong recommendation based on “very low certainty in the evidence of benefits, but high certainty about the harms.”

The guidelines panel also strongly recommends, based on moderate certainty in the evidence of effects, using low-molecular-weight heparin over unfractionated heparin for the initial treatment of VTE in patients with cancer, and suggests, based on “very low certainty in the evidence of effects,” using LMWH over fondaparinux in this setting.

In addition to primary prophylaxis in ambulatory and hospitalized patients and initial VTE treatment, they also address primary prophylaxis for patients with cancer who have a central venous catheter, VTE treatment in surgical patients with cancer, short-term VTE treatment, and long-term VTE treatment.

For example, the guidelines panel conditionally recommends:

• Not using parenteral or oral thromboprophylaxis in patients with cancer and a central venous catheter
• Using LMWH or fondaparinux for surgical patients with cancer
• Using DOACS for the short-term treatment of VTE, and LMWH or DOACs for the long-term treatment of VTE in patients with cancer.

The perils of VTE

VTE in patients with cancer can interfere with treatment, increase mortality risk, and increase costs, the authors noted, adding that VTE can also adversely affect cancer patients’ quality of life.

“Some have even reported the experience of VTE to be more upsetting than that of the cancer,” they wrote. “More than 50% of thrombotic events occur within 3 months of the cancer diagnosis, a time when most cancer treatments will be underway. Patients, who are still coming to terms with a recent cancer diagnosis, often view the occurrence of VTE as a further threat to life, confirmation of the severity of their condition, and a poor prognostic sign.”

Therefore, the new guidelines aim to reduce VTE frequency, risk of bleeding complications, morbidity, and costs, thereby improving quality of life and the patient experience, the authors said, noting that three other recent guidelines on VTEs in patients with cancer have been published: the 2019 American Society of Clinical Oncology guidelines, the 2019 International Initiative on Thrombosis and Cancer guidelines, and the 2020 National Comprehensive Cancer Network guidelines.

The ASH guidelines are similar in many ways to the other guidelines, but differ in some ways, as well. An example is the timing of initiation of pharmacological thromboprophylaxis in patients undergoing cancer-related major abdominal surgery. The ASCO and ITAC guidelines advise starting thromboprophylaxis preoperatively, whereas the ASH guidelines recommend initiating thromboprophylaxis postoperatively, citing “the limited advantages to initiating thromboprophylaxis preoperatively, in addition to the potential bleeding and logistical considerations associated with neuraxial anesthesia.”

These differences highlight a lack of data in that setting and the need for additional studies, the authors said.
 

ASH vs. ASCO

James Douketis, MD, a practicing clinician and professor of medicine at McMaster University, Hamilton, Ont., highlighted another difference between the ASH and ASCO guidelines.

“For the treatment of [cancer-associated thrombosis], ASCO gives a strong recommendation to use LMWH or DOACs (with some caveats), which is easy to follow. ASH, on the other hand, suggests LMWH or a DOAC for the first 7-10 days, DOACs for the first 3-6 months, and back to LMWH or DOACs after 6 months,” he said in an interview.

The recommendation is “very evidence based but ambiguous and not helpful for the practicing clinician,” added Dr. Douketis, who helped develop the ITAC guidelines, but was not part of the ASH or ASCO guideline panels.

ASCO also provides a clear recommendation for giving VTE prophylaxis for 4 weeks after cancer surgery in patients with high VTE risk, whereas ASH gives “a somewhat vague recommendation” for thromboprophylaxis after hospital discharge.

The guidelines are “pretty well aligned” with respect to recommendations on VTE prophylaxis in medical cancer patients receiving chemotherapy, and although the “extremely academic” ASH guidelines were developed by “a superb team using the same evidence and excellent methodology,” they are interpreted in slightly different ways and fall short when it comes to being clinician friendly, Dr. Douketis said.

“At the end of day, for practicing clinicians, the ASH guidelines don’t provide a message that’s easy to digest,” he added.

ASH has, however, provided a resource page that includes tools and information for implementing the guidelines in clinical practice, and will maintain the guidelines “through surveillance for new evidence, ongoing review by experts, and regular revisions,” the authors said.
