This patient was given a diagnosis of disseminated granuloma annulare (DGA). While granuloma annulare usually manifests as a single lesion with a raised erythematous border (often with central pallor or hypopigmentation) it can also manifest as multiple large annular lesions on the extremities and occasionally the trunk, as was seen with this case of DGA.

Although the etiology of DGA is unknown, infections including HIV and hepatitis have been reported as possible triggers. Laboratory testing should be considered if the history or physical examination raises suspicion for either condition. Diabetes has also been associated with the disseminated form and the literature suggests a connection with autoimmune diseases of the liver and thyroid.¹

Watchful waiting is usually the best treatment for localized disease, which can spontaneously regress within a year and is usually asymptomatic. Intralesional steroid injections into the raised annulus are more effective than topical steroids, as the effects of the topical steroids are sometimes augmented by occlusion.

Multiple treatments have been proposed for DGA, including UVA treatments, systemic retinoids, doxycycline, and hydroxychloroquine.¹ Unfortunately, the disseminated form can persist for many years—even with treatment.

Due to the extent of the lesions, the patient in this case was not interested in intralesional steroid injections, and she had already tried topical steroids. She was prescribed topical tacrolimus to reduce the highly visible nature of her lesions.

A 64-year-old White woman with very few medical problems complains of bug bites. She had seen no bugs and had no visible bites. There is no rash. “So what bit me?” she asked, pulling her mask down for emphasis. How should I know? I thought, but didn’t say. She and I have been through this many times.

Before I could respond, she filled the pause with her usual complaints including how hard it is to get an appointment with me and how every appointment with me is a waste of her time. Ignoring the contradistinction of her charges, I took some satisfaction realizing she has just given me a topic to write about: The hateful patient.

Hateful patients are not diagnostic dilemmas, they are the patients whose name on your schedule evokes fury. They are frustrating, troublesome, rude, sometimes racist, misogynistic, depressing, hopeless, and disheartening. They call you, email you, and come to see you just to annoy you (so it seems). And they’re everywhere. According to one study, nearly one in six are “difficult patients.” It feels like more lately because the vaccine has brought haters back into clinic, just to get us.

But hateful patients aren’t new. In 1978, James E. Groves, MD, a Harvard psychiatrist, wrote a now-classic New England Journal of Medicine article about them called: Taking Care of the Hateful Patient. Even Osler, back in 1889, covered these patients in his lecture to University of Pennsylvania students, advising us to “deal gently with this deliciously credulous old human nature in which we work ... restrain your indignation.” But like much of Osler’s advice, it is easier said than done.

Dr. Groves is more helpful, and presents a model to understand them. Difficult patients, as we’d now call them, fall into four stereotypes: dependent clingers, entitled demanders, manipulative help-rejectors, and self-destructive deniers. It’s Dr. Groves’s bottom line I found insightful. He says that, when patients create negative feelings in us, we’re more likely to make errors. He then gives sound advice: Set firm boundaries and learn to counter the countertransference these patients provoke. Don’t disavow or discharge, Dr. Groves advises, redirect these emotions to motivate you to dig deeper. There you’ll find clinical data that will facilitate understanding and enable better patient management. Yes, easier said.

In addition to Dr. Groves’s analysis of how we harm these patients, I’d add that these disagreeable, malingering patients also harm us doctors. The hangover from a difficult patient encounter can linger for several appointments later or, worse, carryover to home. And now with patient emails proliferating, demanding patients behave as if we have an inexhaustible ability to engage them. We don’t. Many physicians are struggling to care at all; their low empathy battery warnings are blinking red, less than 1% remaining.

What is toxic to us doctors is the maelstrom of cognitive dissonance these patients create in us. Have you ever felt relief to learn a difficult patient has “finally” died? How could we think such a thing?! Didn’t we choose medicine instead of Wall Street because we care about people? But manipulative patients can make us care less. We even use secret language with each other to protect ourselves from them, those GOMERs (get out of my emergency room), bouncebacks, patients with status dramaticus, and those ornery FTDs (failure to die). Save yourself, we say to each other, this patient will kill you.

Caring for my somatizing 64-year-old patient has been difficult, but writing this has helped me reframe our interaction. Unsurprisingly, at the end of her failed visit she asked when she could see me again. “I need to schedule now because I have to find a neighbor to watch my dogs. It takes two buses to come here and I can’t take them with me.” Ah, there’s the clinical data Dr. Groves said I’d find – she’s not here to hurt me, she’s here because I’m all she’s got. At least for this difficult patient, I have a plan. At the bottom of my note I type “RTC 3 mo.”

Patients with alopecia areata (AA) appear to have a gut dysbiosis not seen in healthy individuals, according to research presented at the annual meeting of the Society for Investigative Dermatology.

There have been reports of gut microbiome dysbiosis associated with autoimmune diseases such as rheumatoid arthritis, diabetes, and celiac disease. “It is now clear that these events not just shape the immune response in the gut, but also distant sites and immune-privileged organs,” Tanya Sezin, a doctor of natural science from the University of Lübeck (Germany) and Columbia University, New York, said in her presentation.

Whether the gut microbiome may also play a role as an environmental factor in alopecia areata, another T-cell–mediated autoimmune disease for which there are few available treatment options, is being evaluated at the Christiano Laboratory at Columbia University, Dr. Sezin noted. “Much of the difficulty underlying the lack of an effective treatment has been the incomplete understanding of the pathogenesis of AA.”

She also referred to several case reports describing hair growth in patients who received fecal microbiota transplantation (FMT), including a 20-year-old with alopecia universalis, who experienced hair growth after receiving FMT for Crohn’s disease.

Dr. Sezin and colleagues at the lab first performed a study in mice to test whether the gut microbiome was involved in the pathogenesis of AA. Mice given an antibiotic cocktail of ampicillin, neomycin, and vancomycin prior to or at the time of a skin graft taken from a mouse model of AA to induce AA were protected from hair loss, while mice given the antibiotic cocktail after skin grafting were not protected from hair loss.

“16S rRNA sequencing analysis of the gut microbiota revealed a significant shift in gut microbiome composition in animals treated with antibiotics and protected from hair loss, as reflected by significant changes in alpha and beta diversity,” Dr. Sezin explained. “In AA mice, we also observed differential abundance of families from the Bacteroidetes and Firmicutes phyla.” Specifically, Lactobacillus murinus and Muribaculum intestinale were overrepresented in mice with AA.

The investigators then performed 16S rRNA sequencing on 26 patients with AA, who stopped treatment for 30 days beforehand, and 9 participants who did not have AA as controls. “Though we did not observe difference in alpha and beta diversity, we see changes in the relative abundance of several families belonging to the Firmicutes phyla,” in patients with AA, Dr. Sezin said.

In another cohort of 30 patients with AA and 20 participants without AA, who stopped treatment before the study, Dr. Sezin and colleagues found “differences in the relative abundance of members of the Firmicutes and Bacteroides phyla,” including Bacteroides caccae, Prevotella copri, Syntrophomonas wolfei, Blautia wexlerae, and Eubacterium eligens, she said. “Consistent with our findings, there are previous reports in the literature showing gut dysbiosis in several other autoimmune diseases associated with differential regulation of some of the top species we have identified.”

Dr. Sezin said her group is recruiting patients for a clinical trial evaluating FMT in patients with AA. “We plan to study the association between changes in the gut microbiome and immune cell composition in AA patients undergoing FMT,” she said. “Additionally, functional studies in mice are also currently [being conducted] to further pinpoint the contribution of gut microbiome to the pathogenesis of AA.”

When asked during the discussion session if there was any relationship between the skin microbiome and AA, Dr. Sezin said there was no connection found in mice studies, which she and her colleagues are investigating further. “In the human samples, we are currently recruiting more patients and healthy controls to try to get a better understanding of whether we see differences in the skin microbiome,” she added.

Dr. Sezin explained that how the gut microbiota “is really remediated in alopecia areata” is not well understood. “We think that it is possible that we see intestinal permeability in the gut due to the gut dysbiosis that we see in alopecia areata patients, and this might lead to systemic distribution of bacteria, which might cross-react or present cross reactivity with the antigens” identified in AA, which is also being investigated, she said.

FMT not a ‘simple fix’ for AA

Leslie Castelo-Soccio, MD, PhD, a dermatologist at the Children’s Hospital of Philadelphia, who was not involved with the research, said in an interview that the findings presented by Dr. Sezin show how AA shares similarities with other autoimmune diseases. “It does highlight how important the gut microbiome is to human disease, and that differences in relative abundance of bacteria play one part as a trigger in a genetically susceptible person.”

However, while some autoimmune diseases have a big difference in alpha and beta diversity, for example, “this has not been seen in people with alopecia areata,” Dr. Castelo-Soccio pointed out. “The differences are more subtle in terms of amounts of certain bacteria,” she said, noting that, in this study, the biggest differences were seen in the studies of mice.

Dr. Castelo-Soccio also said there may be also be differences in the gut microbiome in children and adults. “The gut microbiome shifts in very early childhood from a very diverse microbiome to a more ‘adult microbiome’ around age 4, which is the age we see the first peak of many autoimmune diseases, including alopecia areata. I think microbiome work in humans needs to focus on this transition point.”

As for the clinical trial at Columbia that is evaluating FMT in patients with AA, Dr. Castelo-Soccio said she is excited. “There is much to learn about fecal transplant for all diseases and about the role of the gut microbiome and environment. Most of what we know for fecal transplant centers on its use for Clostridium difficile infections.”

Patients and their families have been asking about the potential for FMT in alopecia area, Dr. Castelo-Soccio said, but some believe it is a “simple fix” when the reality is much more complex.

“When I speak to patients and families about this, I explain that currently the ‘active ingredient’ in fecal transplants is not definitively established. In any one donor, the community of bacteria is highly variable and can be from batch to batch. While the short-term risks are relatively low – cramping, diarrhea, discomfort, mode of delivery – there are reports of transmission of infectious bacteria from donors like [Escherichia] coli, which have led to severe infections.”

Long-term safety and durability of effects are also unclear, “so we do not know if a patient receiving one [FMT] will need many in the future. We do not know how changing the microbiome could affect the transplant recipient in terms of noninfectious diseases/disorders. We are learning about the role of microbiome in obesity, insulin resistance, mood disorders. We could be ‘fixing’ one trigger of alopecia but setting up [the] patient for other noninfectious conditions,” Dr. Castelo-Soccio said.

Dr. Sezin and Dr. Castelo-Soccio reported no relevant financial disclosures.

However, while some autoimmune diseases have a big difference in alpha and beta diversity, for example, “this has not been seen in people with alopecia areata,” Dr. Castelo-Soccio pointed out. “The differences are more subtle in terms of amounts of certain bacteria,” she said, noting that, in this study, the biggest differences were seen in the studies of mice.

Dr. Castelo-Soccio also said there may be also be differences in the gut microbiome in children and adults. “The gut microbiome shifts in very early childhood from a very diverse microbiome to a more ‘adult microbiome’ around age 4, which is the age we see the first peak of many autoimmune diseases, including alopecia areata. I think microbiome work in humans needs to focus on this transition point.”

As for the clinical trial at Columbia that is evaluating FMT in patients with AA, Dr. Castelo-Soccio said she is excited. “There is much to learn about fecal transplant for all diseases and about the role of the gut microbiome and environment. Most of what we know for fecal transplant centers on its use for Clostridium difficile infections.”

Patients and their families have been asking about the potential for FMT in alopecia area, Dr. Castelo-Soccio said, but some believe it is a “simple fix” when the reality is much more complex.

“When I speak to patients and families about this, I explain that currently the ‘active ingredient’ in fecal transplants is not definitively established. In any one donor, the community of bacteria is highly variable and can be from batch to batch. While the short-term risks are relatively low – cramping, diarrhea, discomfort, mode of delivery – there are reports of transmission of infectious bacteria from donors like [Escherichia] coli, which have led to severe infections.”

Long-term safety and durability of effects are also unclear, “so we do not know if a patient receiving one [FMT] will need many in the future. We do not know how changing the microbiome could affect the transplant recipient in terms of noninfectious diseases/disorders. We are learning about the role of microbiome in obesity, insulin resistance, mood disorders. We could be ‘fixing’ one trigger of alopecia but setting up [the] patient for other noninfectious conditions,” Dr. Castelo-Soccio said.

Dr. Sezin and Dr. Castelo-Soccio reported no relevant financial disclosures.

Spending more free time seated combined with engaging in low physical activity is associated with an increased risk of stroke in adults aged between 40 and 60 years, according to a new analysis.

While the risk of stroke increased more than fourfold among sedentary people under the age of 60, no significant increase in risk was observed among older individuals, according to the study based on self-reported data from more than 140,000 people. This highlights the need for relevant public health messaging directed at younger people, reported lead author, Raed A. Joundi, MD, DPhil, a stroke fellow at the University of Calgary (Alta.), and colleagues, in the paper published in Stroke.

“Sedentary time has increased over the past 2 decades in the United States and Canada, particularly in the young, raising the importance of characterizing its effect on long-term health , ” the investigators wrote. “A better understanding of the risk of sedentary time specific to stroke may be important for public health campaigns to reduce sedentary behavior.” Dr. Joundi and colleagues reviewed data from the Canadian Community Health Survey, including 143,180 healthy individuals without baseline history of cancer, heart disease, or stroke. Those under the age of 40 years were also excluded from the analysis.

Excess sedentary leisure time was defined as 8 or more hours of sedentary leisure time per day, whereas low physical activity was defined as less than 3.5 metabolic equivalent hours per week. The analysis also included a range of demographic and medical covariates, such as age, sex, marital status, smoking status, presence of hypertension, and others.

After a median follow-up of 9.4 years, 2,965 stroke events occurred, with a median time from survey response of 5.6 years. Risk of stroke among individuals aged younger than 60 years who engaged in low physical activity and excess sedentary leisure time was increased 4.5-fold, compared with individuals with low physical activity who were sedentary less than 4 hours per day (fully adjusted hazard ratio, 4.50; 95% confidence interval, 1.64-12.3).
 

Findings highlight benefits of physical activity

Similar risk elevations were not observed among individuals aged 60-79 years, or those older than 80. And among people younger than 60, high physical activity appeared to eliminate the additional risk imposed by excess sedentary leisure time.

“Sedentary time is associated with higher risk of stroke in inactive individuals, but not an active individual, ” Dr. Joundi said in an interview. “So it suggests that there’s two ways to lower risk: One would be to lower your sedentary time, and the other would be to engage in physical activity.”

These interpretations are speculative, Dr. Joundi cautioned, as the study was not interventional. Even so, he said that the findings “bring the spotlight back on physical activity,” thereby aligning with previous research.

“The more you exercise, the more that relationship between sedentary time and poor health outcomes is blunted, and in fact, can be completely negated with enough physical activity,” he said.

How exactly physical activity offers such protection remains unclear, Dr. Joundi added. He speculated that regularity of exercise may be key, with each session counteracting the adverse effects of prolonged sedentary time, which may include reduced blood flow, increased insulin resistance, and inflammatory changes that can affect blood vessels.

“This study is particularly a message for younger individuals,” Dr. Joundi said, suggesting that the findings may alter behavior, as many people have witnessed, or are aware of, the long-term impacts of stroke.

“There’s a sort of social or cognitive aversion to stroke, I think, in the general population, because of how disabling it can be, and how it can lower your quality of life,” he said.
 

Subtle lifestyle changes may be enough.

For those aiming to lower their risk of stroke, Dr. Joundi suggested that subtle lifestyle changes may be enough.

“Ultimately, what we saw is that even minimal amounts of physical activity – walking 3 hours a week, for example – could blunt the impact of sedentary time,” he said. “Doing what you can, even if it’s a small amount, tends to be quite meaningful over a long period of time.”

Daniel T. Lackland, DrPH, professor of epidemiology in the department of neurology at the Medical University of South Carolina, Charleston, offered a similar takeaway, noting that small efforts can lead to great benefits.

“Less intense activity is still better than being sedentary,” he said in an interview. “For many people, if you do get up and you just walk around, move your arms around – do any kind of movement – that’s better than being sedentary.”

Dr. Lackland applauded the practicality of studying sedentary leisure time, versus overall leisure time, as many people can’t control their work environment.

“You can’t do very much about how you work your job,” Dr. Lackland said. “Sometimes we have to sit, and I guess there are things you can do – you can put a treadmill instead of a chair and that kind of thing – but more often than not, you don’t really have that choice to do something. With leisure time, though, you’re in full control. And so what do you do with your leisure time? Do you sit and watch TV, or do you engage in some type of activity? Not necessarily aerobic activity, but some type of activity that would not let you be sedentary. You want to be active as much as you possibly can.”

Dr. Joundi disclosed grant support from the Canadian Institutes of Health Research. The other investigators and Dr. Lackland reported no relevant disclosures.

The U.S. Food and Drug Administration has expanded the indication for the noninvasive BrainsWay Deep Transcranial Magnetic Stimulation (Deep TMS) System to include treatment of comorbid anxiety symptoms in adult patients with depression, the company has announced.

As reported by this news organization, the neurostimulation system has previously received FDA approval for treatment-resistant major depression, obsessive-compulsive disorder, and smoking addiction.

In the August 18 announcement, BrainsWay reported that it has also received 510(k) clearance from the FDA to market its TMS system for the reduction of anxious depression symptoms.

“This clearance is confirmation of what many have believed anecdotally for years – that Deep TMS is a unique form of therapy that can address comorbid anxiety symptoms using the same depression treatment protocol,” Aron Tendler, MD, chief medical officer at BrainsWay, said in a press release.

‘Consistent, robust’ effect

Before receiving approval, the company submitted data on 573 patients who underwent this treatment while participating in 11 studies, which included both randomized controlled trials and open-label studies.

“The data demonstrated a treatment effect that was consistent, robust, and clinically meaningful for decreasing anxiety symptoms in adult patients suffering from major depressive disorder [MDD],” the company said in its release.

Data from three of the randomized trials showed an effect size of 0.3 when compared with a sham device and an effect size of 0.9 when compared with medication. The overall, weighted, pooled effect size was 0.55.

The company noted that in more than 70 published studies with about 16,000 total participants, effect sizes have ranged from 0.2-0.37 for drug-based anxiety treatments.

“The expanded FDA labeling now allows BrainsWay to market its Deep TMS System for the treatment of depressive episodes and for decreasing anxiety symptoms for those who may exhibit comorbid anxiety symptoms in adult patients suffering from [MDD] and who failed to achieve satisfactory improvement from previous antidepressant medication treatment in the current episode,” the company said.

Booster shots to ramp up protection against COVID-19 infection are slated to begin the week of Sept. 20, the Biden administration announced at a press briefing August 18.

Those who received the Pfizer-BioNTech and Moderna vaccines would be eligible to get a booster shot 8 months after they received the second dose of those vaccines, officials said. Information on boosters for those who got the one-dose Johnson & Johnson vaccine will be forthcoming.

“We anticipate a booster will [also] likely be needed,” said U.S. Surgeon General Vivek Murthy, MD. The J&J vaccine was not available in the U.S. until March, he said, and ‘’we expect more data on J&J in the coming weeks, so that plan is coming.”

The plan for boosters for the two mRNA vaccines is pending the FDA’s conducting of an independent review and authorizing the third dose of the Moderna and Pfizer-BioNTech vaccines, as well as an advisory committee of the CDC making the recommendation.

“We know that even highly effective vaccines become less effective over time,” Dr. Murthy said. “Having reviewed the most current data, it is now our clinical judgment that the time to lay out a plan for the COVID-19 boosters is now.”

Research released Aug. 18 shows waning effectiveness of the two mRNA vaccines.

At the briefing, Dr. Murthy and others continually reassured listeners that while effectiveness against infection declines, the vaccines continue to protect against severe infections, hospitalizations, and death.

“If you are fully vaccinated, you still have a high degree of protection against the worst outcomes,” Dr. Murthy said.
 

Data driving the plan

CDC Director Rochelle Walensky, MD, cited three research studies published Aug. 18 in the CDC’s Morbidity and Mortality Weekly Report that helped to drive the decision to recommend boosters.

Analysis of nursing home COVID-19 data from the CDC’s National Healthcare Safety Network showed a significant decline in the effectiveness of the full mRNA vaccine against lab-confirmed COVID-19 infection, from 74.7% before the Delta variant (March 1-May 9, 2021) to 53% when the Delta variant became predominant in the United States. The analysis during the Delta dominant period included 85,000 weekly reports from nearly 15,000 facilities.

Another study looked at more than 10 million New York adults who had been fully vaccinated with either the Moderna, Pfizer, or J&J vaccine by July 25. During the period from May 3 to July 25, overall, the age-adjusted vaccine effectiveness against infection decreased from 91.7% to 79.8%.

Vaccine effectiveness against hospitalization remains high, another study found. An analysis of 1,129 patients who had gotten two doses of an mRNA vaccine showed vaccine effectiveness against hospitalization after 24 weeks. It was 86% at weeks 2-12 and 84% at weeks 13-24.
 

Immunologic facts

Immunologic information also points to the need for a booster, said Anthony Fauci, MD, the chief medical advisor to the president and director of the National Institute of Allergy and Infectious Diseases.

“Antibody levels decline over time,” he said, “and higher antibody levels are associated with higher efficacy of the vaccine. Higher levels of antibody may be needed to protect against Delta.”

A booster increased antibody levels by ‘’at least tenfold and possibly more,” he said. And higher levels of antibody may be required to protect against Delta. Taken together, he said, the data support the use of a booster to increase the overall level of protection.
 

Booster details

“We will make sure it is convenient and easy to get the booster shot,” said Jeff Zients, the White House COVID-19 response coordinator. As with the previous immunization, he said, the booster will be free, and no one will be asked about immigration status.

The plan for booster shots is an attempt to stay ahead of the virus, officials stressed
 

Big picture

Not everyone agrees with the booster dose idea. At a World Health Organization briefing Aug. 18, WHO’s Chief Scientist Soumya Swaminathan, MD, an Indian pediatrician, said that the right thing to do right now ‘’is to wait for the science to tell us when boosters, which groups of people, and which vaccines need boosters.”

Like others, she also broached the ‘’moral and ethical argument of giving people third doses, when they’re already well protected and while the rest of the world is waiting for their primary immunization.”

Dr. Swaminathan does see a role for boosters to protect immunocompromised people but noted that ‘’that’s a small number of people.” Widespread boosters ‘’will only lead to more variants, to more escape variants, and perhaps we’re heading into more dire situations.”

“We know that even highly effective vaccines become less effective over time,” Dr. Murthy said. “Having reviewed the most current data, it is now our clinical judgment that the time to lay out a plan for the COVID-19 boosters is now.”

Research released Aug. 18 shows waning effectiveness of the two mRNA vaccines.

At the briefing, Dr. Murthy and others continually reassured listeners that while effectiveness against infection declines, the vaccines continue to protect against severe infections, hospitalizations, and death.

“If you are fully vaccinated, you still have a high degree of protection against the worst outcomes,” Dr. Murthy said.
 

Data driving the plan

CDC Director Rochelle Walensky, MD, cited three research studies published Aug. 18 in the CDC’s Morbidity and Mortality Weekly Report that helped to drive the decision to recommend boosters.

Analysis of nursing home COVID-19 data from the CDC’s National Healthcare Safety Network showed a significant decline in the effectiveness of the full mRNA vaccine against lab-confirmed COVID-19 infection, from 74.7% before the Delta variant (March 1-May 9, 2021) to 53% when the Delta variant became predominant in the United States. The analysis during the Delta dominant period included 85,000 weekly reports from nearly 15,000 facilities.

Another study looked at more than 10 million New York adults who had been fully vaccinated with either the Moderna, Pfizer, or J&J vaccine by July 25. During the period from May 3 to July 25, overall, the age-adjusted vaccine effectiveness against infection decreased from 91.7% to 79.8%.

Vaccine effectiveness against hospitalization remains high, another study found. An analysis of 1,129 patients who had gotten two doses of an mRNA vaccine showed vaccine effectiveness against hospitalization after 24 weeks. It was 86% at weeks 2-12 and 84% at weeks 13-24.
 

Immunologic facts

Immunologic information also points to the need for a booster, said Anthony Fauci, MD, the chief medical advisor to the president and director of the National Institute of Allergy and Infectious Diseases.

“Antibody levels decline over time,” he said, “and higher antibody levels are associated with higher efficacy of the vaccine. Higher levels of antibody may be needed to protect against Delta.”

A booster increased antibody levels by ‘’at least tenfold and possibly more,” he said. And higher levels of antibody may be required to protect against Delta. Taken together, he said, the data support the use of a booster to increase the overall level of protection.
 

Booster details

“We will make sure it is convenient and easy to get the booster shot,” said Jeff Zients, the White House COVID-19 response coordinator. As with the previous immunization, he said, the booster will be free, and no one will be asked about immigration status.

The plan for booster shots is an attempt to stay ahead of the virus, officials stressed
 

Big picture

Not everyone agrees with the booster dose idea. At a World Health Organization briefing Aug. 18, WHO’s Chief Scientist Soumya Swaminathan, MD, an Indian pediatrician, said that the right thing to do right now ‘’is to wait for the science to tell us when boosters, which groups of people, and which vaccines need boosters.”

Like others, she also broached the ‘’moral and ethical argument of giving people third doses, when they’re already well protected and while the rest of the world is waiting for their primary immunization.”

Dr. Swaminathan does see a role for boosters to protect immunocompromised people but noted that ‘’that’s a small number of people.” Widespread boosters ‘’will only lead to more variants, to more escape variants, and perhaps we’re heading into more dire situations.”

Pfizer has recalled four more lots of the smoking cessation drug varenicline (Chantix), according to an Aug. 16 update on the U.S. Food and Drug Administration website.

In a new FDA MedWatch, the agency notes that these 0.5 mg/1 mg tablets are being recalled because of the presence of N-nitroso-varenicline, a nitrosamine impurity, at a level higher than Pfizer’s acceptable intake limit.

On July 2, the FDA reported that Pfizer had voluntarily recalled nine lots of the drug for this reason. As reported by this news organization, the company added three more lots to the recall a few weeks later. The new recall now brings to 16 the number of lots that have been recalled.

In the update, the FDA noted that, although long-term ingestion of the impurity “may be associated with a theoretical potential increased cancer risk in humans,” there is no immediate risk in taking this medication. The agency added that no related adverse events (AEs) have been reported.

The four additional lots included in the newest recall are as follows:

• 00018522 (expiration date: August 2021).
• 00018523 (expiration date: August 2021).
• 00018739 (expiration date: August 2021).
• 00018740 (expiration date: August 2021).

The recalled lots were distributed in the United States and Puerto Rico from June 2019 to June 2021.

As before, the FDA noted that the benefits of stopping smoking “outweigh the theoretical potential cancer risk” from varenicline’s impurity.

It added that, although the impurities may increase risk for cancer if a high level of exposure continues over a long period, the drug is intended as a short-term treatment to aid in smoking cessation.

For now, clinicians should report any AEs from varenicline to the FDA’s MedWatch program, and patients taking this treatment should consult with their health care practitioner or pharmacy, the update notes.

Preliminary data from seven states suggests that breakthrough COVID-19 infections among vaccinated people may be on the rise because of the more contagious Delta variant.

Breakthrough cases accounted for about one in five newly diagnosed cases in six of the states, according to the New York Times. Hospitalizations and deaths among vaccinated people may be higher than previously thought as well.

“Remember when the early vaccine studies came out, it was like nobody gets hospitalized, nobody dies,” Robert Wachter, MD, chairman of the department of medicine at the University of California, San Francisco, said in an interview. “That clearly is not true.”

The New York Times analyzed data in seven states – California, Colorado, Massachusetts, Oregon, Utah, Vermont, and Virginia – that are tracking the most detailed information. The trends in these states may not reflect the numbers throughout the country, the newspaper reported.

Even still, the numbers back up the idea that vaccinated people may need booster shots this fall to support their earlier vaccine doses. Federal health officials are scheduled to approve the extra shots in coming weeks, potentially in September. The first people to receive booster shots will likely be health care workers and nursing home residents who took the first vaccines in December and January.

“If the chances of a breakthrough infection have gone up considerably, and I think the evidence is clear that they have, and the level of protection against severe illness is no longer as robust as it was, I think the case for boosters goes up pretty quickly,” Dr. Wachter said.

Previous analyses of breakthrough cases included data from June and earlier, the newspaper reported. But since July, COVID-19 cases have soared again because of the Delta variant, and the most recent numbers show an uptick among vaccinated people. In Los Angeles County, for instance, fully vaccinated people account for 20% of new COVID-19 cases, which is up from 11% in May, 5% in April, and 2% in March, according to a late July report from the Los Angeles County Department of Public Health.

What’s more, breakthrough infections in the seven states accounted for 12%-24% of COVID-19 hospitalizations in those states. About 8,000 breakthrough hospitalizations have been reported to the CDC. Still, the overall numbers remain low – in California, for instance, about 1,615 people have been hospitalized with breakthrough infections, which accounts for 0.007% of the state’s 22 million vaccinated people, the Times reported.

The breakthrough infections appear to be more severe among vaccinated people who are older or have weakened immune systems. About 74% of breakthrough cases are among adults 65 or older, the CDC reported.

The increase may shift how vaccinated people see their risks for infection and interact with loved ones. Public health officials have suggested that people follow some COVID-19 safety protocols again, such as wearing masks in public indoor spaces regardless of vaccination status.

As the Delta variant continues to circulate this fall, public health researchers will be researching more about breakthrough cases among vaccinated people, including whether they have prolonged symptoms and how easily they may pass the virus to others.

“I think some of us have been challenged by the numbers of clusters that we’ve seen,” Michael Osterholm, PhD, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, told this news organization.

“I think that really needs to be examined more,” he said.

It is well known that survivors of critical care are at heightened risk of mental health disorders even months afterward they are discharged, but it’s less clear what factors might contribute to those outcomes. A new attempt to identify risk factors for post-ICU depression, anxiety, or posttraumatic stress disorder, as well as worse quality of life, paints a complex picture.

Age, mental preexisting mental health concerns, acute emotional stress at the time of critical care, and post-care physical impairment all may play a role, according to the multicenter, prospective cohort study conducted in Brazil, which was published in CHEST .

Previous systematic reviews have shown raised frequencies mental health disorders following ICU discharge, including anxiety (32%-40%), depression (29%-34%), and PTSD (16%-23%). Few studies have looked at the potential impact of preexisting conditions or post-ICU disability on these outcomes, yet that information is critical to key to designing effective prevention and rehabilitation interventions.

The results suggest that preexisting mental health and factors associated with the critical illness, which have gained attention as potential factors, aren’t sufficient to explain these outcomes. “Our data suggest that the network of potential risk factors for mental illness among patients who have been discharged from the ICU is much more complex and may involve risk factors from multiple domains. ... Long-term mental health disorders after critical illness may be the result of the interaction among stressors before ICU stay, during ICU stay, and after ICU stay, calling attention to the need for interdisciplinary and multifaceted strategies aimed at preventing and screening for mental health disorders after ICU discharge,” Cassiano Teixeira, MD, PhD, of the Postgraduation of Pulmonology–Federal University of Rio Grande do Sul, Brazil, and colleagues wrote.

The researchers also noted that some risk factors could be screened and may be modifiable, including anxiety and depression symptoms at ICU discharge, as well as reduced physical function status.
 

Complications or risk factors?

The findings are significant, though they may represent complications of emotional distress following ICU stays, rather than risk factors that predict it, according to an accompanying editorial. The author, O. Joseph Bienvenu III, MD, PhD, who is a professor of psychiatry and behavioral sciences at Johns Hopkins Medicine, Baltimore. He called for prospective studies to determine the predictive value of these factors. “If we are to improve long-term mental health after critical illnesses, this predictive information will be vital to selective prevention efforts.”

Dr. O. Joseph Bienvenu

Potential interventions could include psychological treatment in the ICU, ICU follow-up clinics, support groups, and cognitive-behavioral therapy, among others. Whichever approach is used, it should be targeted, according to Dr. Bienvenu, since patients who have greater emotional distress seem to gain the most benefit from such interventions.

The researchers examined outcomes among 579 adults who had spent at least 72 hours in the ICU. The median age was 61 years, and 47% were women.

Six months after release from the ICU, telephone assessments by trained researchers revealed that 48% had impairment in physical function, compared with the time preceding ICU admission. 36.2% of participants had a mental health disorder: 24.2% reported anxiety, 20.9% had depression, and 15.4% had PTSD.

Increasing numbers of psychiatric syndromes, from 0 to 3, was associated with worse scores on the mental dimension on the health-related quality of life (HRQoL) score, but there was no relationship with scores on the physical dimension.
 

Risks to mental health

Clinical characteristics associated with risk of anxiety at 6 months post discharge included being 65 years or older (prevalence ratio, 0.63; P = .009), a history of depression (PR, 1.52; P = .009), anxiety at discharge (PR, 1.65; P = .003), depression at discharge (HR, 1.44; P = .02), physical dependence (PR, 1.48; P = .01), and reduced physical functional status at 6 months post discharge (PR, 1.38; P = .04).

Characteristics associated with depression at 6 months post discharge included a history of depression (PR, 1.78; P = .001), symptoms of depression at discharge (PR, 3.04; P < .001), and reduced physical functional status at 6 months (PR, 1.53; P = .01).

Characteristics associated with PTSD at 6 months post discharge were depression symptoms at discharge (PR, 1.70; P = .01), physical dependence (PR, 1.79; P = .01), and reduced physical status at 6 months (PR, 1.62; P = .02).

Characteristics associated with any mental health disorder included higher education (PR, 0.74; P = .04), a history of depression (PR, 1.32; P = .02), anxiety symptoms at discharge (PR, 1.55; P = .001), depression symptoms at discharge (PR, 1.50; P = .001), and physical dependence at 6 months following discharge (PR, 1.66; P < .001).

“The lower HRQoL found in ICU survivors with mental health disorders in comparison with those without is a reason for concern. This finding, in association with the higher prevalence of psychiatric syndromes among ICU survivors, reinforces the importance of assessing anxiety, depression, and PTSD symptoms among ICU survivors, because these syndromes typically are long lasting and underdiagnosed, and their occurrence may affect quality of life, survival, and costs in the context of care after ICU discharge,” according to the researchers.

The authors of the study and Dr. Bienvenu have no relevant financial disclosures.

Clinical characteristics associated with risk of anxiety at 6 months post discharge included being 65 years or older (prevalence ratio, 0.63; P = .009), a history of depression (PR, 1.52; P = .009), anxiety at discharge (PR, 1.65; P = .003), depression at discharge (HR, 1.44; P = .02), physical dependence (PR, 1.48; P = .01), and reduced physical functional status at 6 months post discharge (PR, 1.38; P = .04).

Characteristics associated with depression at 6 months post discharge included a history of depression (PR, 1.78; P = .001), symptoms of depression at discharge (PR, 3.04; P < .001), and reduced physical functional status at 6 months (PR, 1.53; P = .01).

Characteristics associated with PTSD at 6 months post discharge were depression symptoms at discharge (PR, 1.70; P = .01), physical dependence (PR, 1.79; P = .01), and reduced physical status at 6 months (PR, 1.62; P = .02).

Characteristics associated with any mental health disorder included higher education (PR, 0.74; P = .04), a history of depression (PR, 1.32; P = .02), anxiety symptoms at discharge (PR, 1.55; P = .001), depression symptoms at discharge (PR, 1.50; P = .001), and physical dependence at 6 months following discharge (PR, 1.66; P < .001).

“The lower HRQoL found in ICU survivors with mental health disorders in comparison with those without is a reason for concern. This finding, in association with the higher prevalence of psychiatric syndromes among ICU survivors, reinforces the importance of assessing anxiety, depression, and PTSD symptoms among ICU survivors, because these syndromes typically are long lasting and underdiagnosed, and their occurrence may affect quality of life, survival, and costs in the context of care after ICU discharge,” according to the researchers.

Preterm and early birth is associated with an increased risk of autism independent of genetic or environmental factors, according to new research published in Pediatrics.

Although previous studies have linked preterm births to an increased risk of autism – one 2017 study published in Cerebral Cortex found that 27.4% of the children born extremely preterm were diagnosed with autism – Casey Crump, MD, PhD, said potential causality, sex-specific differences, and association with early-term births were still unclear.

“Preterm birth had previously been linked with higher risk of autism; however, several important questions remained unanswered,” said Dr. Crump, professor and vice chair for research at the department of family medicine and community health and professor of epidemiology in the department of population health science and policy at Icahn School of Medicine at Mount Sinai New York. “To our knowledge, [our study] is the largest to date of gestational age at birth in relation to autism, and one of the first to investigate sex-specific differences, early term birth, or the influence of shared familial factors.”

Dr. Crump and colleagues examined data from more than 4 million infants born in Sweden between 1973 and 2013 who were followed-up for autism spectrum disorder identified from nationwide outpatient and inpatient diagnoses through December 2015. Children born between 22 and 27 weeks were considered extremely preterm, those born between 28 and 33 week were characterized as very to moderate preterm, and those born between 34 and 36 weeks were considered late preterm. Early-term births are characterized as infants born between 37 and 38 weeks and children born between 39 and 41 weeks were considered term births.

They found that 6.1% of those born extremely preterm were diagnosed with autism. Meanwhile, autism spectrum disorder prevalences were 2.6% for very to moderate preterm, 1.9% for late preterm, 2.1% for all preterm, and 1.6% for early term, compared with 1.4% for term birth.

The researchers’ analysis showed that preterm and early birth were associated with a significantly increased risk of autism in males and females. Children who were born extremely preterm had an approximately fourfold increased risk of autism. Researchers also found that each additional week of gestation was associated with a 5% lower prevalence of autism spectrum disorder (ASD) on average.

“The elevated risk even in [late preterm] infants is not completely surprising because a number of investigators have shown higher incidences of early cognitive, language motor and impairment, and school problems ... and psychiatric disorders, some of which may extend to adulthood,” Elisabeth McGowan, MD, who was not involved in the study, said in a solicited editorial commentary about the study.

Dr. Crump believes the association between preterm birth and autism may be because of increased inflammatory marker levels. A 2009 study published in Reproductive Sciences found that increased proinflammatory cytokine levels have been associated with the timing and initiation of preterm birth, and also have been detected in the brain and cerebrospinal fluid of individuals with autism “and may play a key role in its pathogenesis,” Dr. Crump said.

“Inflammatory-driven alteration of neuronal connections during critical periods of brain development may be central to the development of autism,” Dr. Crump explained.

However, Dr. Crump said that, although the relative risks of autism were higher in those born preterm, the absolute risk of the condition is low.

“The report by Crump is in many ways a definitive accounting of the elevated rates of ASD in preterm infants,” said Dr. McGowan, associate professor of pediatrics at the Women and Infants Hospital, Providence, R.I. “And although the impact of prematurity on brain development may be part of the causal chain resulting in ASD (or other neurodevelopmental outcomes), these factors are operating in a complex biological landscape, with pathways to ASD outcomes that can be expected to be heterogeneous.”

ASD is a developmental condition that affects about 1 in 54 children, according to the Centers for Disease Control and Prevention. Many children are not diagnosed with ASD until later in childhood, which in some cases delays treatment and early intervention. ASD may be detected as early as 18 months, but the average age of diagnosis for ASD is 4.3 years, according to the CDC.

“Children born prematurely need early evaluation and long-term follow-up to facilitate timely detection and treatment of autism, especially those born at the earliest gestational ages,” Dr. Crump said in an interview. “In patients of all ages, gestational age at birth should be routinely included in history-taking and medical records to help identify in clinical practice those born preterm or early term. Such information can provide additional valuable context for understanding patients’ health and may facilitate earlier evaluation for autism and other neurodevelopmental conditions in those born prematurely.”

Dr. Crump and colleagues said more research is needed to understand the biologic mechanisms linking preterm birth with higher risks of autism, which “may reveal new targets for intervention at critical windows of neurodevelopment to improve the disease trajectory.”

Experts interviewed did not disclose any relevant financial relationships.
