I woke up from a nap on Tuesday, April 20, to a barrage of text messages and social media alerts about the Derek Chauvin verdict. Messages varied in content, from “let’s celebrate,” to “just so exciting,” to “finally.” As I took in the sentiments of others, I could barely sense what, if any, sentiments I had of my own.

There I sat, a Black DEI [diversity, equity, and inclusion] consultant who calls herself a “psychiatrist-activist,” but slept through the landmark court decision for policing African Americans and felt almost nothing about it.

However, I did have feelings about other matters such as the slide decks due for my client, sending reassuring text messages about the hospitalization of a friend’s child, and the 2 weeks of patient notes on my to-do list. So why did I feel emotionally flatlined about an issue that should stimulate the opposite – emotional intensity?

The answer to “why” could be attributed to a number of psychological buzz words like trauma, grief, desensitization, dissociation, numbness, or my new favorite term, languishing.

Despite the applicability of any of the above, I think my emotional flattening has more to do with the fact that in addition to the guilty verdict, I also woke up to news that 16-year-old Ma’Khia Bryant had been shot by a police officer in Columbus, Ohio.

I asked myself: How can anyone find time to grieve, nevertheless celebrate when (young) Black people continue to be killed by the police?

While it hurts to see individuals who look like me being shot by police, or even emboldened citizens, my hurt likely pales in comparison to someone who grew up surrounded by police gun violence. I grew up solidly middle class, lived in a house at the end of a cul-de-sac in a semi-gated community, and have many years ahead of me to reach my earning potential as a physician in one of the most liberal cities in the nation. While I have the skin color that puts me at risk of being shot by police due to racism, I am in a cushy position compared to other Black people who live in cities or neighborhoods with more police shootings.

Given this line of thinking, it seems clearer to me why I do not feel like celebrating, but instead, feel grateful to be alive. Not only do I feel grateful to be alive, but alive with the emotional stamina to help White people understand their contributions to the widespread oppression that keeps our society rooted in white supremacy.

This brings me to my point of what I want people, especially physicians, to know about the guilty verdict of Derek Chauvin: Some of us cannot really celebrate until there is actual police reform. This is not to say that anyone is wrong to celebrate, as long as there is an understanding that a landmark court decision can represent a drop in the bucket for Black and Brown people who risk being shot by the police while unarmed just for being Black or Brown.

Meanwhile, White men like Kyle Rittenhouse who are peaceably arrested after shooting a man with a semi-automatic weapon receive donations from a Virginia police lieutenant; a policeman who, in a possible world, could one day pull me over while driving through Virginia given its proximity to Washington D.C., where I currently live.

Black and Brown people cannot fully celebrate until there is actual police reform, and reform across American institutions like the health care system. Celebration comes when the leaders who run schools, hospitals, and courtrooms look more like the numbers actually reflected in U.S. racial demographics and look less like Derek Chauvin.

Until there are more doctors who look like the racial breakdown of the nation, Black and Brown patients can never fully trust their primary care doctors, orthopedic surgeons, and psychiatrists who are White. While this reality may sound harsh, it is the reality for many of us who are dealing with trauma, grief, desensitization, dissociation, emotional numbness, or languishment resulting from racist experiences.

People of color cannot and will not stop protesting in the streets, being the one who always brings up race in the meeting, or disagreeing that the new changes are “not enough” until there is actual anti-racist institutional reform. More importantly, the efforts of people of color can be made more powerful working collectively with White allies.

But we need White allies who recognize their tendency to perceive “progress” in racial equality. We need White allies who recognize that despite the passage of the Civil Rights Act, the two-time election of a Black president, and the guilty verdict of Derek Chauvin, there is still so much work to do.

Energy drink doom

Who doesn’t need some caffeine to get going in the morning and keep moving throughout the day? Whether it’s tea, coffee, or energy drinks, people can get addicted to caffeinated beverages when there are only so many hours in a day and way too much work to get done.

Alexander Mirokhin/Fotolia.com

That’s what happened to a 21-year-old college student who powered down four 16-ounce cans of energy drink – each with double the amount of caffeine in an ordinary cup of coffee – every day for 2 years. Now, if you’ve ever overdone it with caffeine, you know there are some uncomfortable side effects, like shaking and anxiety. In this case, the student reported migraines, tremors, and heart palpitations. Instead of being able to focus better on his work, he had trouble concentrating.

Over time, after these side effects took a turn for the worse and became shortness of breath and weight loss, he visited St. Thomas’ Hospital in London, where physicians diagnosed him with both heart and renal failure.

Excessive consumption of energy drinks is known to cause issues such as high blood pressure and irregular heart beat, so if that’s your fuel of choice, it might be worth cutting down. Maybe take a morning run to get the blood pumping – in a good way – instead?
 

Loneliness may be hazardous to your health

Sometimes loneliness can feel like it affects your physical health, but according to a study there’s a possibility that it actually does.

Back in the 1980s, researchers from the University of Eastern Finland started monitoring almost 3,000 middle-aged men. They’ve kept up with the participants until the present day, and the results have been staggering. After an average follow-up of over 20 years, 25% of participants developed cancer and 11% died from cancer, and the increase in risk from loneliness was about 10%, regardless of age, lifestyle, and BMI.

What does that say about preventive care? The researchers think these data are cause enough to pay attention to loneliness as a health issue along with smoking and weight.

Social interactions and relationships play important roles in human mental health, of course, but this is pretty solid evidence that they play a role in physical health too. As the researchers said, “Awareness of the health effects of loneliness is constantly increasing. Therefore, it is important to examine, in more detail, the mechanisms by which loneliness causes adverse health effects.”

So, as we progress through this pandemic, maybe you should join that social group on Facebook? Who knows what kind of effect it could have on your health?
 

An ounce of prevention is worth 12 ounces of lager

COVID-19 vaccine refusal is now a thing, and there’s no law that says people have to be immunized against our newest, bestest buddy, SARS-CoV-2, but the folks who skip it are missing out. And no, we’re not talking about immunity against disease.

Governor Jim Justice

We’re talking … FREE STUFF!

Corporate America has stepped up and is now rewarding those who get the COVID-19 vaccine:

• Budweiser will give a free beer to anyone – anyone over age 21, that is – with proof of vaccination until May 16.
• Show a vaccination card at a Krispy Kreme and you can get a free glazed doughnut, every day. You don’t even need to buy anything.
• White Castle will give you a free dessert-on-a-stick just for showing proof of vaccination. No purchase is required, but the offer ends May 31.

But wait, there’s more!

Even the public sector is getting in on the giveaway action. Gov. Jim Justice announced April 26 that West Virginia will give a $100 savings bond to any resident aged 16-35 years who receives a COVID-19 vaccine. It must make sense, because the governor broke out a white board to show residents he’s done the math.

One closing thought: How cool would it be if he was named to the Supreme Court, so he could be Justice Justice?


 

Where no shirt has gone before

Space. The final frontier, for both humanity and for shirts. Specifically, it’s a new frontier for the Bio-Monitor smart shirt, a tank-top filled with sensors that monitor the wearer’s stats, such as heart and breathing rate, oxygen saturation, skin temperature, and blood pressure. And you thought space was just for finding a new human habitat and growing steak.

This shirt is already used by athletes to assess performance and by people with limited mobility to monitor health, so its potential impending usage by astronauts makes sense. Space is a pretty extreme environment, to put it mildly, and there’s a lot we still don’t know about how the human body reacts to it. Traditionally, astronauts hook themselves up to separate devices so their stats can be measured, a method which captures only snapshots of their bodies. By wearing the shirt constantly, the astronauts can be measured constantly, so scientists and doctors can see how the body deals with microgravity during normal activities and sleep. It also reduces stress, as there is no psychological impact of having to report in for constant health checks.

For the test, astronauts wore the shirt for 72 hours before flight and for 72 hours during flight. The shirts passed this first test with flying colors; in addition to providing accurate and more consistent stats monitoring than traditional methods, scientists on the ground determined that the astronauts recorded far less physical activity during flight than preflight, a finding in line with previous studies.

And before you question whether or not a tank top is really appropriate for space, just remember, Picard pulled it off at the end of “First Contact,” and that’s arguably the best Star Trek movie. So there’s certainly precedent.

Barrett’s esophagus occurred in nearly 12% of patients who underwent esophagogastroduodenoscopy after sleeve gastrectomy, but it was not associated with postoperative gastroesophageal reflux disease (GERD), based on data from 10 studies that totaled 680 adult patients.

ChrisPole/thinkstock

Sleeve gastrectomy has become more popular in recent years as an effective strategy for patients with severe obesity, wrote Bashar J. Qumseya, MD, of the University of Florida, Gainesville, and colleagues. However, GERD is a common concern for patients undergoing sleeve gastrectomy and is the major risk factor for Barrett’s esophagus. However, the prevalence of Barrett’s esophagus in the sleeve gastrectomy population has not been examined.

In a meta-analysis published in Gastrointestinal Endoscopy, the researchers reviewed 10 studies that totaled 680 patients who underwent esophagogastroduodenoscopy 6 months to 10 years after a sleeve gastrectomy procedure. The primary outcome was Barrett’s esophagus prevalence in sleeve gastrectomy patients, with the prevalence of erosive esophagitis and GERD at follow-up as secondary outcomes.

Overall, 54 patients developed Barrett’s esophagus, for a pooled prevalence of 11.6%, and all cases were nondysplastic and de novo. There was no significant association between Barrett’s esophagus and the presence of postoperative GERD, the researchers said (odds ratio, 1.74; P = .37).

However, the rate of erosive esophagitis increased by 86% in five studies with long-term follow-up and by 35% in two studies with short-term follow-up, which suggests an increased risk of 13% each year after sleeve gastrectomy, the researchers noted.

Besides the risk of Barrett’s esophagus after sleeve gastrectomy, “the risk of [erosive esophagitis] is also of significant interest and shares the same pathophysiology with [Barrett’s esophagus] and GERD,” they emphasized.

The study findings were limited by several factors including the small sample size and the focus on Barrett’s esophagus rather than erosive esophagitis or GERD as the primary outcome, the researchers noted. However, the results indicate that sleeve gastrectomy patients are at increased risk for Barrett’s esophagus, and larger studies are needed to better understand the pathophysiology. Furthermore, although there is some debate regarding the risk of GERD and erosive esophagitis after sleeve gastrectomy, the authors wrote that the data from their study showed a “consistent and substantial trend” toward more erosive esophagitis after sleeve gastrectomy.

“Gastroenterologists, primary care providers, and bariatric surgeons should be aware” of the data and should discuss the risks of sleeve gastrectomy with patients before the procedure, including the risks and benefits of postprocedure screening for Barrett’s esophagus, they concluded.
 

Consider surveillance for Barrett’s

The study is important because of the increased rates of GERD and potentially Barrett’s esophagus that have been noted after sleeve gastrectomy, Gyanprakash A. Ketwaroo, MD, of Baylor College of Medicine, Houston, said in an interview.

“Many of these studies have been small, and the findings of meta-analyses have been limited by high heterogeneity,” he noted. “With the rise in popularity of sleeve gastrectomy, it is important to accurately assess potential long-term complications.”

Dr. Ketwaroo said he was not surprised by the study findings given several reports of increased GERD after sleeve gastrectomy. “Given the accepted pathophysiology of Barrett’s esophagus, I anticipated increased risk of Barrett’s esophagus after sleeve gastrectomy as well.

“Clinicians should consider surveillance for Barrett’s esophagus after sleeve gastrectomy, and possible early proton pump inhibitor use for both GERD/erosive esophagitis and Barrett’s esophagus chemoprophylaxis. Patients with longer-segment or dysplastic Barrett’s esophagus prior to sleeve gastrectomy may have to be monitored more closely after surgery,” he said.

Dr. Ketwaroo noted that the study was limited by the small sample size, “with only approximately 50 patients with Barrett’s esophagus after surgery among 680 overall.” He emphasized that “we will need a much larger prospective study to confirm this finding. Additionally, I would want to explore if sleeve gastrectomy increases rate of progression of dysplasia in those who develop Barrett’s esophagus.”

The study received no outside funding. Lead author Dr. Qumseya had no financial conflicts to disclose. Dr. Ketwaroo serves on the GI & Hepatology News editorial advisory board.

Qumseya, MD, of the University of Florida, Gainesville, and colleagues. However, GERD is a common concern for patients undergoing sleeve gastrectomy and is the major risk factor for Barrett’s esophagus. However, the prevalence of Barrett’s esophagus in the sleeve gastrectomy population has not been examined.

In a meta-analysis published in Gastrointestinal Endoscopy, the researchers reviewed 10 studies that totaled 680 patients who underwent esophagogastroduodenoscopy 6 months to 10 years after a sleeve gastrectomy procedure. The primary outcome was Barrett’s esophagus prevalence in sleeve gastrectomy patients, with the prevalence of erosive esophagitis and GERD at follow-up as secondary outcomes.

Overall, 54 patients developed Barrett’s esophagus, for a pooled prevalence of 11.6%, and all cases were nondysplastic and de novo. There was no significant association between Barrett’s esophagus and the presence of postoperative GERD, the researchers said (odds ratio, 1.74; P = .37).

However, the rate of erosive esophagitis increased by 86% in five studies with long-term follow-up and by 35% in two studies with short-term follow-up, which suggests an increased risk of 13% each year after sleeve gastrectomy, the researchers noted.

Besides the risk of Barrett’s esophagus after sleeve gastrectomy, “the risk of [erosive esophagitis] is also of significant interest and shares the same pathophysiology with [Barrett’s esophagus] and GERD,” they emphasized.

The study findings were limited by several factors including the small sample size and the focus on Barrett’s esophagus rather than erosive esophagitis or GERD as the primary outcome, the researchers noted. However, the results indicate that sleeve gastrectomy patients are at increased risk for Barrett’s esophagus, and larger studies are needed to better understand the pathophysiology. Furthermore, although there is some debate regarding the risk of GERD and erosive esophagitis after sleeve gastrectomy, the authors wrote that the data from their study showed a “consistent and substantial trend” toward more erosive esophagitis after sleeve gastrectomy.

“Gastroenterologists, primary care providers, and bariatric surgeons should be aware” of the data and should discuss the risks of sleeve gastrectomy with patients before the procedure, including the risks and benefits of postprocedure screening for Barrett’s esophagus, they concluded.
 

Consider surveillance for Barrett’s

The study is important because of the increased rates of GERD and potentially Barrett’s esophagus that have been noted after sleeve gastrectomy, Gyanprakash A. Ketwaroo, MD, of Baylor College of Medicine, Houston, said in an interview.

“Many of these studies have been small, and the findings of meta-analyses have been limited by high heterogeneity,” he noted. “With the rise in popularity of sleeve gastrectomy, it is important to accurately assess potential long-term complications.”

Dr. Ketwaroo said he was not surprised by the study findings given several reports of increased GERD after sleeve gastrectomy. “Given the accepted pathophysiology of Barrett’s esophagus, I anticipated increased risk of Barrett’s esophagus after sleeve gastrectomy as well.

“Clinicians should consider surveillance for Barrett’s esophagus after sleeve gastrectomy, and possible early proton pump inhibitor use for both GERD/erosive esophagitis and Barrett’s esophagus chemoprophylaxis. Patients with longer-segment or dysplastic Barrett’s esophagus prior to sleeve gastrectomy may have to be monitored more closely after surgery,” he said.

Dr. Ketwaroo noted that the study was limited by the small sample size, “with only approximately 50 patients with Barrett’s esophagus after surgery among 680 overall.” He emphasized that “we will need a much larger prospective study to confirm this finding. Additionally, I would want to explore if sleeve gastrectomy increases rate of progression of dysplasia in those who develop Barrett’s esophagus.”

The study received no outside funding. Lead author Dr. Qumseya had no financial conflicts to disclose. Dr. Ketwaroo serves on the GI & Hepatology News editorial advisory board.

Barrett’s esophagus occurred in nearly 12% of patients who underwent esophagogastroduodenoscopy after sleeve gastrectomy, but it was not associated with postoperative gastroesophageal reflux disease (GERD), based on data from 10 studies that totaled 680 adult patients.

Pfizer CEO Albert Bourla, DVM, PhD, says an oral drug the company is developing to treat COVID-19 symptoms could be available to the public by the end of the year.

“If all goes well, and we implement the same speed that we are, and if regulators do the same, and they are, I hope that (it will be available) by the end of the year,” Dr. Bourla said on CNBC’s Squawk Box.

So far, the only antiviral drug authorized for use with COVID-19 is remdesivir, which is produced by Gilead Sciences and must be administered by injection in a health care setting.

An oral drug like the one Pfizer is developing could be taken at home and might keep people out of the hospital.

“Particular attention is on the oral because it provides several advantages,” Dr. Bourla said. “One of them is that you don’t need to go to the hospital to get the treatment, which is the case with all the injectables so far. You could get it at home, and that could be a game-changer.”

The drug might be effective against the emerging variants, he said. Pfizer is also working on an injectable antiviral drug.

Pfizer, with its European partner BioNTech, developed the first coronavirus vaccine authorized for use in the United States and Europe. The Pfizer pill under development would not be a vaccine to protect people from the virus but a drug to treat people who catch the virus.

The company announced in late March that it was starting clinical trials on the oral drug.

In a news release, the company said the oral drug would work by blocking protease, a critical enzyme that the virus needs to replicate. Protease inhibitors are used in medicines to treat HIV and hepatitis C.

A coronavirus vaccine that could be taken as a pill may enter clinical trials in the second quarter of 2021. The oral vaccine is being developed by Oravax Medical, a new joint venture of the Israeli-American company Oramed and the Indian company Premas Biotech. So far, all coronavirus vaccines are injectable.

People with psoriasis have a higher risk of infection with COVID-19 than the general population, but some systemic treatments appear to lower risk in patients, compared with those on topical therapy, a new study finds.

“Our study results suggest that psoriasis is an independent risk factor for COVID-19 illness,” study coauthor Jeffrey Liu, a medical student at the University of Southern California, Los Angeles, said in an interview after he presented the findings at the American Academy of Dermatology Virtual Meeting Experience. “And our findings are consistent with the hypothesis that certain systemic agents may confer a protective effect against COVID-19 illness.”

Mr. Liu and coinvestigators used a Symphony Health dataset to analyze the health records of 167,027 U.S. patients diagnosed with psoriasis and a control group of 1,002,162 patients. The participants, all at least 20 years old, had been treated for psoriasis or psoriatic arthritis from May 2019 through Jan. 1, 2020, and were tracked until Nov. 11, 2020.

The ages and races of peoples in the two groups were roughly similar. Overall, 55% were women and 75% were White, and their average age was 58 years. Type 2 diabetes was more common in the psoriasis group than the control group (23% vs. 16%), as was obesity (27% vs. 15%). Of the patients with psoriasis, 60% were on topical treatments, 19% were on oral therapies, and 22% were on biologic therapy, with only a few taking both oral and biologic therapies.

After adjustment for age and gender, patients with psoriasis were 33% more likely than the control group to develop COVID-19 (adjusted incidence rate ratio, 1.33; 95% confidence interval, 1.23-1.38; P < .0001).

In a separate analysis, the gap persisted after adjustment for demographics and comorbidities: Patients with psoriasis had a higher rate of COVID-19 infection vs. controls (adjusted odds ratio, 1.18; 95% CI, 1.13-1.23; P < .0001). Among all patients, non-White race, older age, and comorbidities were all linked to higher risk of COVID-19 (all P < .0001).

Psoriasis might make patients more vulnerable to COVID-19 because the presence of up-regulated genes in psoriatic skin “may lead to systemic hyperinflammation and sensitization of patients with psoriasis to proinflammatory cytokine storm,” Mr. Liu said. This, in turn, may trigger more severe symptomatic disease that requires medical treatment, he said.

Reduced risk, compared with topical therapies

After adjustment for age and gender, those treated with TNF-alpha inhibitors, methotrexate, and apremilast (Otezla) all had statistically lower risks of COVID-19 vs. those on topical therapy (aIRR, 0.82; 95% CI, 0.69-0.95; P < .0029 for TNF-alpha inhibitors; aIRR, 0.75; 95% CI, 0.67-0.86; P < .0001 for methotrexate; and aIRR, 0.69; 95% CI, 0.55-0.85; P < .0006 for apremilast).

Reduced risk held true for those in the separate analysis after adjustment for comorbidities and demographics (respectively, aOR, 0.87; 95% CI, 0.77-1.00; P < .0469; aOR, 0.81; 95% CI, 0.71-0.92; P < .0011; and aOR, 0.70; 95% CI, 0.57-0.87; P < .0014).

Apremilast and methotrexate may boost protection against COVID-19 by inhibiting the body’s production of cytokines, Mr. Liu said.

One message of the study is that “dermatologists should not be scared of prescribing biologics or oral therapies for psoriasis,” the study’s lead author Jashin J. Wu, MD, of the Dermatology Research and Education Foundation in Irvine, Calif., said in an interview.

However, the results on the effects of systemic therapies were not all positive. Interleukin (IL)–17 inhibitors were an outlier: After adjustment for age and gender, patients treated with this class of drugs were 36% more likely to develop COVID-19 than those on oral agents (aIRR, 1.36; 95% CI, 1.13-1.63; P < .0009).

Among patients on biologics, those taking IL-17 inhibitors had the highest risk of COVID-19, Mr. Liu said. “The risk was higher in this class regardless of reference group – general population, the topical cohort, and the oral cohort,” he said. “This may relate to the observation that this biologic class exerts more broad immunosuppressive effects on antiviral host immunity. Notably, large meta-estimates of pivotal trials have observed increased risk of respiratory tract infections for patients on IL-17 inhibitors.”

In an interview, Erica Dommasch, MD, MPH, of the department of dermatology at Beth Israel Deaconess Medical Center, Boston, cautioned that “the data from this study is very hard to interpret.”

It’s likely that some patients with psoriasis on systemic medications “may have been the most careful about limiting exposures,” she said. “Thus, it’s hard to account for behavioral changes in individuals that may have led to the decreased incidence in psoriasis in patients on systemic agents versus topical therapy alone.”

Patients with psoriasis may also be tested more often for COVID-19, and unmeasured comorbidities like chronic kidney disease may play a role too, she said. Still, she added, “it’s reassuring that the authors did not find an increased rate of COVID among psoriasis patients on systemic agents versus topicals alone.” And she agreed with Dr. Wu about the importance of treating psoriasis with therapy beyond topical treatments during the pandemic: “Providers should feel comfortable prescribing systemic medications to psoriasis patients when otherwise appropriate.”

As for the next steps, Dr. Wu said, “we will be exploring more about the prognosis of COVID-19 infection in psoriasis patients. In addition, we will be exploring the relationship of COVID-19 infection with other inflammatory skin diseases, such as atopic dermatitis.”

No study funding is reported. Dr. Wu discloses investigator, consultant, or speaker relationships with AbbVie, Almirall, Amgen, Arcutis, Aristea Therapeutics, Boehringer Ingelheim, Bristol-Myers Squibb, Dermavant, Dr. Reddy’s Laboratories, Eli Lilly, Galderma, Janssen, LEO Pharma, Mindera, Novartis, Regeneron, Sanofi Genzyme, Solius, Sun Pharmaceutical, UCB, Valeant Pharmaceuticals North America, and Zerigo Health.

After hinting that new guidelines on outdoor mask-wearing were coming, the Centers for Disease Control and Prevention on April 27 officially gave a green light to fully vaccinated people gathering outside in uncrowded activities without the masks that have become so common during the COVID-19 pandemic.

It is a minor – but still significant – step toward the end of pandemic restrictions.

“Over the past year, we have spent a lot of time telling Americans what they cannot do, what they should not do,” CDC director Rochelle Walensky, MD, MPH, said at a White House press briefing. “Today, I’m going to tell you some of the things you can do if you are fully vaccinated.”

President Joe Biden affirmed the new guidelines at a press conference soon after the CDC briefing ended.

“Starting today, if you are fully vaccinated and you’re outdoors and not in a big crowd, you no longer need to wear a mask,” he said, adding “the bottom line is clear: If you’re vaccinated, you can do more things, more safely, both outdoors as well as indoors.”

President Biden emphasized the role science played in the decision, saying “The CDC is able to make this announcement because our scientists are convinced by the data that the odds of getting or giving the virus to others is very, very low if you’ve both been fully vaccinated and are out in the open air.”

President Biden also said these new guidelines should be an incentive for more people to get vaccinated. “This is another great reason to go get vaccinated now. Now,” he said.

The CDC has long advised that outdoor activities are safer than indoor activities.

“Most of transmission is happening indoors rather than outdoors. Less than 10% of documented transmissions in many studies have occurred outdoors,” said Dr. Walensky. “We also know there’s almost a 20-fold increased risk of transmission in the indoor setting, than the outdoor setting.”

Dr. Walensky said the lower risks outdoors, combined with growing vaccination coverage and falling COVID cases around the country, motivated the change.

The new guidelines come as the share of people in the United States who are vaccinated is growing. About 37% of all eligible Americans are fully vaccinated, according to the CDC. Nearly 54% have had at least one dose.

The new guidelines say unvaccinated people should continue to wear masks outdoors when gathering with others or dining at an outdoor restaurant.

And vaccinated people should continue to wear masks outdoors in crowded settings where social distancing might not always be possible, like a concert or sporting event. People are considered fully vaccinated when they are 2 weeks past their last shot

The CDC guidelines say people who live in the same house don’t need to wear masks if they’re exercising or hanging out together outdoors.

You also don’t need a mask if you’re attending a small, outdoor gathering with fully vaccinated family and friends, whether you’re vaccinated or not.

The new guidelines also say it’s OK for fully vaccinated people to take their masks off outdoors when gathering in a small group of vaccinated and unvaccinated people, but suggest that unvaccinated people should still wear a mask.

A cohort study of psoriasis patients in Denmark found that a nonmedical switch from brand name adalimumab to adalimumab biosimilars was not associated with drug retention at 1 year. And another study, a small, single-center retrospective study of patients with hidradenitis suppurativa (HS), found that administration of infliximab and biosimilar infliximab were associated with similar and significant improvement in disease.

Both studies were published online in April in JAMA Dermatology and add to mounting evidence that biosimilars may be interchangeable in certain dermatologic conditions.

“Biosimilars are an exciting innovation in the field,” Joseph Zahn, MD, assistant professor of dermatology at George Washington University, Washington, said in an interview. “Their efficacy and price point will allow patients greater access to effective treatment.” To date, biosimilars approved in the United States that could be prescribed by dermatologists include those for rituximab, etanercept, adalimumab, and infliximab.

In the trial from Denmark, Nikolai Loft, MD, of the University of Copenhagen and colleagues evaluated outcomes following a mandatory medical switch from the brand name adalimumab, referred to as adalimumab originator, to adalimumab biosimilars among 726 individuals who were enrolled in a Danish nationwide registry of patients treated with biologics since 2007. The primary outcome was 1-year drug retention in patients switching to adalimumab biosimilars compared with patients treated with adalimumab originator.

The study population consisted of 348 patients with at least 2 years of exposure to adalimumab who had switched from originator to adalimumab biosimilars (a mean age of 52 and 72% male) and 378 patients who served as the adalimumab cohort (a mean age of 51 and 71% male). When the researchers compared the 1-year drug retention rates between the adalimumab biosimilar cohort and the adalimumab originator cohort, the rates were similar (92% vs. 92.1%, respectively).

The hazard ratios for other outcomes were similar as well. Specifically, the crude hazard ratios were 1.02 (P = .94) for all causes of drug discontinuation, 0.82 (P = .60) for insufficient effect, and 1.41 (P = .50) for adverse events (AEs) in the adalimumab biosimilar cohort, compared with the adalimumab originator cohort.

“Overall, results for any AEs were contradicting, but certain AEs were more prevalent in the adalimumab biosimilar cohort,” the authors wrote. Dermatologic AEs and AEs in the “other” category “were more prevalent, which could be attributable to more patients experiencing injection site reactions as a result of larger volumes and differences in excipients and syringes in the adalimumab biosimilars and the adalimumab originator.” Other potential explanations they offered were the nocebo effect and greater awareness of AEs among practitioners and patients.

“This study concludes that, when switched to a biosimilar medication, patients do not have worse control of their psoriasis nor do they switch to other medications,” Dr. Zahn, who was asked to comment about these results, said in the interview. “However, there was a trend toward a higher number of side effects in the biosimilar group. The main takeaway point from this study is that biosimilars of adalimumab seem to be relatively interchangeable in patients with psoriasis without loss of efficacy or significant increase in side effects that lead to a medication change for the patient.”

The researchers acknowledged certain limitations of their study, including the fact that it was limited to Danish patients and that individual AEs could not be examined. “Moreover, the surveillance of AEs is not as vigilant as in clinical trials, and AEs are most likely underreported,” they wrote. “Although no major differences were found when switching from adalimumab originator to adalimumab biosimilar versions, it was not possible to assess the performance of individual adalimumab biosimilar versions in this study.”

In the second study, Christopher Sayed, MD, associate professor of dermatology, University of North Carolina, Chapel Hill, and colleagues retrospectively evaluated the effectiveness of infliximab-abda versus infliximab administration in the treatment of 34 patients with HS who were cared for at the university’s dermatology clinic. Patients were treated with either agent for at least 10 weeks. The infliximab treatment group consisted of 20 patients with a mean age of 42 years who were mostly female (17; 85%), while the infliximab-abda treatment group included 14 patients with a mean age of 36 years who also were mostly female (13; 93%).

Both groups received loading doses of 10 mg/kg at weeks 0, 2, and 6, and treatment was continued with a maintenance dose administered every 4-8 weeks. The patients were followed between February 2016 and June 2020 and the primary outcome measure was Hidradenitis Suppurative Clinical Response (HiSCR), which was defined as at least a 50% decrease in inflammatory nodule count without any increase in the number of abscesses or draining sinuses.

The researchers found that 71% of patients in the infliximab-abda treatment group achieved a HiSCR, compared with 60% of their counterparts in the infliximab treatment group, a difference that did not reach statistical significance (P = .47). Three patients in the infliximab treatment group experienced AEs, compared with none in the infliximab-abda treatment group.

“The data are promising,” Dr. Zahn said. “Although this is a small study with a limited number of patients, it suggests that this particular biosimilar may be a reasonable or possibly even equivalent alternative to infliximab. A larger, prospective trial will be needed before we can be sure the results are equivalent.”

Dr. Sayed and colleagues noted certain limitations of their study, including the retrospective design and the use of concomitant medications by some participants. “There is also a risk of selection bias because copay and medication assistance programs are not available for infliximab-abda for patients with HS,” they wrote.

In an editorial accompanying the two studies, Mark Lebwohl, MD, professor of dermatology, Icahn School of Medicine at Mount Sinai, New York, wrote that the introduction of biosimilars have been justified by “the hope that lower costs” will increase availability of treatments to patients with moderate to severe psoriasis. “Inroads in the U.S. market, however, have been limited,” he added, and there is concern that they “may be used to prevent access to newer interleukin-17 blockers and interleukin-23 blockers for which biosimilars are available and that do not carry the boxed warnings found on tumor necrosis factor blockers.”

Dr. Loft reported receiving personal fees from Eli Lilly and Janssen outside of the submitted work. Many of his coauthors reporting having numerous financial conflicts of interest with the pharmaceutical industry. The HS study was supported by a public health service research award from the National Institutes of Health. Dr. Sayed reported receiving personal fees or personal fees paid to the institution from AbbVie, Novartis, Chemocentryx, GlaxoSmithKline, Incyte, InflaRx, and UCB. No other disclosures were reported. Dr. Lebwohl disclosed receiving research funds from companies including AbbVie, Amgen, Boehringer Ingelheim, Eli Lilly, and Incyte; and receiving personal fees from multiple companies, outside of the submitted work. Dr. Zahn reported having no disclosures.

Use of the Johnson & Johnson COVID-19 vaccine should resume in the United States for all adults, the Food and Drug Administration and Centers for Disease Contol and Prevention said April 23, although health care providers should warn patients of the risk of developing the rare and serious blood clots that caused the agencies to pause the vaccine’s distribution earlier this month.

Do your patients think that getting COVID-19 is fully protective against subsequent reinfection? Tell it to the Marines.

A study of U.S. Marine recruits on their way to boot camp at Parris Island, S.C., showed that those who were seropositive at baseline, indicating prior exposure to SARS-CoV-2, remained at some risk for reinfection. They had about one-fifth the risk of subsequent infection, compared with seronegative recruits during basic training, but reinfections did occur.

The study, by Stuart C. Sealfon, MD, of Icahn School of Medicine at Mount Sinai in New York, and colleagues, was published in The Lancet Respiratory Medicine.

“Although antibodies induced by initial infection are largely protective, they do not guarantee effective SARS-CoV-2 neutralization activity or immunity against subsequent infection,” they wrote.

An infectious disease specialist who was not involved in the study said that the findings provide further evidence about the level of immunity acquired after an infection.

“It’s quite clear that reinfections do occur, they are of public health importance, and they’re something we need to be mindful of in terms of advising patients about whether a prior infection protects them from reinfection,” Mark Siedner, MD, MPH, a clinician and researcher in the division of infectious diseases at Massachusetts General Hospital, Boston, said in an interview.

The study results reinforce that “not all antibodies are the same,” said Sachin Gupta, MD, an attending physician in pulmonary and critical care medicine at Alameda Health System in Oakland, Calif. “We’re seeing still that 10% of folks who have antibodies can get infected again,” he said in an interview.

CHARM initiative

Dr. Sealfon and colleagues presented an analysis of data from the ironically named CHARM (COVID-19 Health Action Response for Marines) prospective study.

CHARM included U.S. Marine recruits, most of them male, aged 18-20 years, who were instructed to follow a 2-week unsupervised quarantine at home, after which they reported to a Marine-supervised facility for an additional 2-week quarantine.

At baseline, participants were tested for SARS-CoV-2 immunoglobulin G (IgG) seropositivity, defined as a dilution of 1:150 or more on receptor-binding domain and full-length spike protein enzyme-linked immunosorbent assay (ELISA).

The recruits filled out questionnaires asking them to report any of 14 specific COVID-19–related symptoms or any other unspecified symptom, as well as demographic information, risk factors, and a brief medical history.

Investigators tested recruits for SARS-CoV-2 infection by polymerase chain reaction (PCR) assay at weeks 0, 1, and 2 of quarantine, and any who had positive PCR results during quarantine were excluded.

Participants who had three negative swab PCR results during quarantine and a baseline serology test at the beginning of the supervised quarantine period – either seronegative or seropositive – then went on to enjoy their basic training at the Marine Corps Recruit Depot, Parris Island, S.C.

The participants were followed prospectively with PCR tests at weeks 2, 4, and 6 in both the seropositive and seronegative groups, and sera were obtained at the same time.
 

Holes in immunologic armor

Full data were available for a total of 189 participants who were seropositive and 2,247 who were seronegative at enrollment.

In all, 19 of 189 seropositive recruits (10%) had at least one PCR test positive for SARS-CoV-2 infection during the 6-week follow-up period. This translated into an incidence of 1.1 cases per person-year.

Of the 2,247 participants seronegative at baseline, 1,079 tested positive (6.2 cases per person-year; incidence rate ratio 0.18).

It appeared that antibodies provided some protection for seropositive recruits, as evidenced by a higher likelihood of infection among those with lower baseline full-length spike protein IgG titers than in those with higher baseline titers (hazard ratio 0.4, P < .001).

Among the seropositive participants who did acquire a second SARS-CoV-2 infection, viral loads in mid-turbinate nasal swabs were about 10-fold lower than in seronegative recruits who acquired infections during follow-up.

“This finding suggests that some reinfected individuals could have a similar capacity to transmit infection as those who are infected for the first time. The rate at which reinfection occurs after vaccines and natural immunity is important for estimating the proportion of the population that needs to be vaccinated to suppress the pandemic,” the investigators wrote.

Baseline neutralizing antibody titers were detected in 45 of the first 54 seropositive recruits who remained PCR negative throughout follow-up, but also in 6 of 19 seropositive participants who became infected during the 6 weeks of observation.
 

Lessons

Both Dr. Siedner and Dr. Gupta agreed with the authors that the risks for reinfection that were observed in young, physically fit people may differ for other populations, such as women (only 10% of seropositive recruits and 8% of seronegative recruits were female), older patients, or those who are immunocompromised.

Given that the adjusted odds ratio for reinfection in this study was nearly identical to that of a recent British study comparing infection rates between seropositive and seronegative health care workers, the risk of reinfection for other young adults and for the general population may be similar, Dr. Sealfon and colleagues wrote.

Adding to the challenge of reaching herd immunity is the observation that some patients who have recovered from COVID-19 are skeptical about the need for further protection.

“There are patients who feel like vaccination is of low benefit to them, and I think these are the same people who would be hesitant to get the vaccine anyway,” Dr. Gupta said.

Although no vaccine is perfect – the vaccine failure rate from the mRNA-based vaccines from Moderna and Pfizer/Biontech is about 5% – the protections they afford are unmistakable, Dr. Siedner said.

“I think it’s important to make the distinction that most postvaccination infections by and large have been very mild,” he said. “In people with normal immune systems, we have not seen an onslaught of postvaccination infections requiring hospitalization. Even if people do get infected after vaccination, the vaccines protect people from severe infection, and that’s what we want them to do.”

The investigators stated, “Young adults, of whom a high proportion are asymptomatically infected and become seropositive in the absence of known infection, can be an important source of transmission to more vulnerable populations. Evaluating the protection against subsequent SARS-CoV-2 infection conferred by seropositivity in young adults is important for determining the need for vaccinating previously infected individuals in this age group.”

The study was funded by the Defense Health Agency and Defense Advanced Research Projects Agency. Dr. Sealfon, Dr. Siedner, and Dr. Gupta have no conflicts of interest to report. Dr. Gupta is a member of the editorial advisory board for this publication.

Do your patients think that getting COVID-19 is fully protective against subsequent reinfection? Tell it to the Marines.

A study of U.S. Marine recruits on their way to boot camp at Parris Island, S.C., showed that those who were seropositive at baseline, indicating prior exposure to SARS-CoV-2, remained at some risk for reinfection. They had about one-fifth the risk of subsequent infection, compared with seronegative recruits during basic training, but reinfections did occur.

The study, by Stuart C. Sealfon, MD, of Icahn School of Medicine at Mount Sinai in New York, and colleagues, was published in The Lancet Respiratory Medicine.

“Although antibodies induced by initial infection are largely protective, they do not guarantee effective SARS-CoV-2 neutralization activity or immunity against subsequent infection,” they wrote.

An infectious disease specialist who was not involved in the study said that the findings provide further evidence about the level of immunity acquired after an infection.

“It’s quite clear that reinfections do occur, they are of public health importance, and they’re something we need to be mindful of in terms of advising patients about whether a prior infection protects them from reinfection,” Mark Siedner, MD, MPH, a clinician and researcher in the division of infectious diseases at Massachusetts General Hospital, Boston, said in an interview.

The study results reinforce that “not all antibodies are the same,” said Sachin Gupta, MD, an attending physician in pulmonary and critical care medicine at Alameda Health System in Oakland, Calif. “We’re seeing still that 10% of folks who have antibodies can get infected again,” he said in an interview.

CHARM initiative

Dr. Sealfon and colleagues presented an analysis of data from the ironically named CHARM (COVID-19 Health Action Response for Marines) prospective study.

CHARM included U.S. Marine recruits, most of them male, aged 18-20 years, who were instructed to follow a 2-week unsupervised quarantine at home, after which they reported to a Marine-supervised facility for an additional 2-week quarantine.

At baseline, participants were tested for SARS-CoV-2 immunoglobulin G (IgG) seropositivity, defined as a dilution of 1:150 or more on receptor-binding domain and full-length spike protein enzyme-linked immunosorbent assay (ELISA).

The recruits filled out questionnaires asking them to report any of 14 specific COVID-19–related symptoms or any other unspecified symptom, as well as demographic information, risk factors, and a brief medical history.

Investigators tested recruits for SARS-CoV-2 infection by polymerase chain reaction (PCR) assay at weeks 0, 1, and 2 of quarantine, and any who had positive PCR results during quarantine were excluded.

Rat-ting out coronavirus

Did you know there is a possibility that giant rodents could rat out coronavirus? Not many people are keen on the presence of a 3-foot-long African giant pouched rat, but they have already been trained to sniff out diseases that are dangerous to humans, such as brucellosis and tuberculosis, according to researchers at the University of Glasgow.

Professor Dan Haydon and his associates believe there is a good possibility that the rats can be trained to sniff out COVID-19. Dogs have been helpful in sniffing for COVID-19 at airports and are being trained to detect it through armpit sweat, making detection of the virus easier for travelers and staff. Even robots have gotten into the COVID-19 detecting act.

Since African giant pouched rats can grow to be the size of a small dog and “are easily tamed as companion animals,” it seems likely that they have the potential to do the same. That is, sniffing for COVID-19, not appearing at your local airport. That’s still gross.
 

Stay healthy, get a parasite bestie

The key to health could actually be swimming around in your gut. Researchers from University College London have found that a parasitic worm could be the answer to longevity and avoidance of chronic diseases.

The seeming immunity from inflammatory diseases such as arthritis, diabetes, and multiple sclerosis may come from helminth parasites, or hookworms – parasites that have been coexisting harmlessly with the human body for thousands of years. The investigators went so far as to call them “old friends,” but the kind that you rarely see at reunions or call up for a favor.

As a result of modern sanitation and improved hygiene, humans and hookworms are seeing much less of each other, which may be a factor in the rise of “aging-associated inflammation” such as COVID-19 symptoms, they suggested. So is there a way to get these old friends back?

“Restorative hookworm treatments” could help with heart disease or dementia, according to the investigators, but maybe you’re not totally on board with getting an actual parasite in your system. We get it. There are helminth-derived proteins that have already been tested to get the job done.

Maybe old friends really do make the best friends.
 

I love the smell of microbe-infected aerosols in the morning

Have you gone into a public restroom and just stood around for a while appreciating the fine aromas? No? You haven’t? You do your business and get out? Well, it’s a good thing you act like a normal person, because the aerosols released when toilets flush can contain all sorts of nasty bacteria and viruses.

©fasterhorses/Thinkstock

The authors of a new study published in Physics of Fluids came to this groundbreaking conclusion by going to a public bathroom, sticking particle counters above a urinal and a toilet, and letting them sit for a while. After 3 hours and 100 flushes, the ambient level of particles 0.3-3 mcm in diameter had increased dramatically, with particles sized 0.5-1 mcm particularly prone to lingering. For those particles, the level from baseline increased by over 200%.

This is a major concern, the researchers said, because the sort of microbes that are expelled through feces, urine, and vomit can include some pretty nasty things. Ebola, noroviruses that can cause food poisoning, and even good old SARS-CoV-2 can be expelled from the body but remain viable for a time in these aerosols. The researchers recommended improving the ventilation systems in restrooms so that aerosols don’t hang around for hours at a time. Plus, it might make the place not smell like a, uh, public restroom.

Not to question the research and the people behind it, but we’re not sure how necessary it was to give people another reason not to hang out in a place where hundreds, if not thousands, of people come to relieve themselves. There’s a reason we’re supposed to “stop and smell the roses” and not “stop and smell the public bathroom.”
 

World ends not with a bang but with a cheeseburger

Speaking of old sayings, one of our favorites, “You are what you eat,” may offer a culinary explanation for those who do enjoy the ambiance of a fine, aerosol-infested public restroom.

That explanation involves the high-calorie, high-fat smorgasbord known as the Western diet and some mice who were forced to consume it. Those mice, it turns out, were more anxious and less cognitively advanced than their counterparts who were not eating “highly palatable, energy dense foods (e.g., high saturated fat, high sugar) that are commonly consumed by humans,” according to the authors of a recent literature review.

“Consumption of a Western diet is related to poorer cognitive performance across the lifespan,” the investigators said, adding that consumption of a Western diet “during critical early life stages of development has negative consequences on various cognitive abilities later in adulthood.”

To show their appreciation for the sacrifices these brave test subjects had made in the name of science, the scientists released the Western diet–addled rodents from captivity. Not only did they survive and thrive in the wilds of darkest suburbia, but within 6 months almost half of them were running for Congress.
