COVID cases spike as questions remain about Omicron’s threat
The best way to stay protected is by getting vaccinated and boosted, they said.
“For the unvaccinated, you’re looking at a winter of severe illness and death – for yourselves, families, and the hospitals who may soon overwhelm,” White House COVID-19 Response Coordinator Jeff Zients said at a news briefing Dec. 17. “We need the American people to do their part.”
The Omicron variant has been detected in at least 39 states and 75 countries, according to CDC director Rochelle Walensky, MD.
The strain is more transmissible than the already highly infectious Delta variant, and although there was early evidence that it caused more mild disease, she said that is likely because many of those infected have been vaccinated and boosted.
“Although Delta continues to circulate widely in the United States, Omicron is increasing rapidly and we expect it to become the dominant strain in the United States, as it has in other countries, in the coming weeks,” Dr. Walensky said.
The United States is averaging close to 1,300 deaths from COVID-19 each day. New cases, deaths, and hospitalizations are higher now than in the previous winter – before vaccines were so widely available. The New York Times reported on Dec. 17 that new infections in Connecticut and Maine have grown 150% in the past 2 weeks, and Ohio and Indiana are seeing hospitalization rates nearing the worst of 2020-2021’s winter surge.
Dueling reports released recently gave cause for relief and concern about Omicron.
A study from South Africa released on Dec. 14 shows lower hospitalizations during the first 3 weeks of the Omicron wave than during earlier waves from other variants. That’s the good news.
The concerning news is out of the United Kingdom, where Imperial College London reported Dec. 17 that the risk of reinfection with COVID-19 from Omicron is more than 5 times as high and that cases of Omicron-based COVID-19 are doubling every 2 days.
What’s more, the study “finds no evidence of Omicron having lower severity than Delta, judged by either the proportion of people testing positive who report symptoms, or by the proportion of cases seeking hospital care after infection. However, hospitalization data remains very limited at this time,” the researchers said.
“We have no evidence that the virus itself is more mild,” Eric Topol, MD, executive vice president of Scripps Research and editor-in-chief of Medscape, told PBS NewsHour. “Until we have that, we have to assume that people who don’t have any protection are highly vulnerable to getting very ill.”
The White House COVID-19 team continues to urge parents and guardians to get their children vaccinated, especially in anticipation of a post-holiday spike. Dr. Walensky said the CDC’s vaccine advisory board met on Dec. 16 to continue the safety discussion about COVID-19 vaccinations in children.
So far, 20 million children under 17 and 5 million under 11 have received their shots.
“Looking specifically at vaccine safety data from over 50,000 children 5-11 years old, we found no evidence of serious safety concerns,” Dr. Walensky said.
Top infectious disease expert Anthony S. Fauci, MD, highlighted the importance of getting vaccinated and boosted to avoid serious disease from Delta and Omicron.
“We’re in a situation where we are now facing a very important Delta surge and we are looking over our shoulder at an oncoming Omicron surge,” he said. “The optimum protection is fully vaccinated plus a boost.”

Small myocarditis risk now seen for adenovirus-based COVID-19 vaccine
The first large population study to investigate the association between different COVID-19 vaccines types and cardiac effects and adverse events shows a small increase in the risk for acute myocarditis with both the mRNA-based vaccines and – in what may a first in the literature – an adenovirus-vector vaccine.
The excess risk was seen following the first dose of the ChAdOc1 (AstraZeneca/Oxford), the adenovirus-based vaccine, and the mRNA-based BNT162b2 (Pfizer/BioNTech). It was observed after first and second doses of the mRNA-1273 (Moderna) vaccine.
The incidence rate ratios for myocarditis 1-7 days after the first AstraZeneca, Pfizer, and Moderna injections were 1.76, 1.45, and 8.38, respectively, and 23.1 after the second dose of the Moderna vaccine.
“There’s a bit more uncertainty and worry about mRNA vaccines because it’s quite a new vector for vaccination and, therefore, there’s been more focus on the potential side effects,” said Nicholas Mills, MD.
“But it doesn’t surprise me the signal is present for all types of vaccines because they’re designed to generate a systemic immune response and that is, unfortunately, where you can cause small risks for immune-mediated illnesses like myocarditis,” Dr. Mills, from the University of Edinburgh, told this news organization. Dr. Mills is a coauthor on the study, published Dec. 14 in Nature Medicine.
To put the risks in context, the group estimated between 1 and 10 additional myocarditis hospitalizations or deaths per 1 million people vaccinated, but 40 excess myocarditis events per million following a positive SARS-CoV-2 test result.
As reported, rates of excess myocarditis events associated with a first dose were 2 per million injections of the AstraZeneca vaccine, 1 per million for the Pfizer vaccine, and 6 per million with the Moderna vaccine.
Following a second dose, there were 10 additional myocarditis events per million people receiving the Moderna vaccine and none among recipients of the AstraZeneca or Pfizer vaccines.
“It was particularly seen within the first 7 days of the first dose, which is very consistent with what we see in people who have viral myocarditis,” Dr. Mills said. “So it looks like a real signal but it’s very small.”
The results are in line with previous studies of the Pfizer vaccine in Israel and studies of the Moderna vaccine in the United States, Biykem Bozkurt, MD, PhD, professor of medicine at Baylor College of Medicine, Houston, told this news organization.
“What this paper does is confirm that cardiovascular complications – and they are only looking at a small component of those cardiovascular complications – are markedly higher with the COVID-19 infection than with the vaccines,” she said.
It also adds a new twist to the search for the mechanisms of myocarditis, which has focused on the immunogenicity of the RNA in the Pfizer and Moderna vaccines but also hypothesized that molecular mimicry between the SARS-CoV-2 spike glycoprotein and cell antigens, antibody production against cardiac proteins, and testosterone may play a role.
“But now it doesn’t look like the risk is solely confined to the mRNA vaccine platform because it’s also happening with the adenovirus,” Dr. Bozkurt said. “The mechanisms require future experimental and clinical research and we’ll need more granular data with cohorts that are closely followed up as well as subclinical follow-up.”
James de Lemos, MD, professor of medicine at the University of Texas Southwestern Medical Center, Dallas, and cochair of the American Heart Association’s COVID-19 CVD Registry, said he was also not surprised by a myocarditis signal with AstraZeneca’s adenovirus vaccine.
“Looking at relative risks has biological implications, but the clinical and public health implications are that the absolute risk with the adenovirus is trivial. And you see that with their estimations of absolute risk where it’s literally sort of a needle in the haystack of 1 or 2 per million,” he said in an interview.
Large-scale data
The investigators examined the rates of hospital admission or death from myocarditis, pericarditis, and cardiac arrhythmia in the 28 days following SARS-CoV-2 vaccination or infection by linking the English National Immunisation Database of COVID-19 vaccination with a national patient-level health care database of 38.6 million people, aged 16 years or older, vaccinated from Dec.1, 2020, to Aug. 24, 2021.
The number of people admitted to the hospital or who died during the study period was 1,615 for myocarditis, 1,574 for pericarditis, and 385,508 for cardiac arrhythmia.
There was no evidence of an increased risk for pericarditis or cardiac arrhythmia following vaccination, except for arrhythmia in the 28 days following a second dose of the Moderna vaccine (IRR, 1.46).
In contrast, the risk was increased for pericarditis (IRR, 2.79) and cardiac arrhythmia (IRR, 5.35) in the 28 days following a positive SARS-CoV-2 test result.
Although the scale of the analysis allows for more precise estimates than what’s been possible in smaller data sets, there is the challenge of diagnosing COVID-19 from billing codes and the potential for ascertainment bias, noted Dr. de Lemos.
“Having said that, I think it’s a really important study, because it’s the first study to put the incidence in context in the same general population the risks of myocarditis with various vaccines and with COVID-19,” he said.
“That’s really important and provides a lot of reassurance for those who are trying to balance the risks and benefits of vaccination.”
Analyses by sex and age
A subgroup analysis by age showed increased risks for myocarditis with the mRNA vaccines only in those younger than 40, whereas no association was found with the Oxford adenovirus vaccine.
“We’re not seeing any signal here that would make us change the recommendation for vaccination in children as a consequence of this risk,” Dr. Mills said during a press briefing.
Dr. Bozkurt pointed out, however, that the estimated excess in myocarditis events following a second dose of the Moderna vaccine in these younger adults reportedly exceeded that for SARS-CoV-2 infection (15 per million vs. 10 per million).
“For that age group, it’s concerning and needs further clarification. This hasn’t been seen before,” she said.
The average age was 39 years for those receiving two doses of the Moderna vaccine and 55 for recipients of the Pfizer and Oxford vaccines. The Moderna vaccine wasn’t rolled out until April 2021 in the United Kingdom, the authors noted, so the number of patients who received this vaccine is lower.
Although reports have suggested young males are at greater risk for myocarditis after vaccination, an analysis by sex found that women had an increased risk for myocarditis after a first dose of the AstraZeneca (IRR, 1.40) and Pfizer (IRR, 1.54) vaccines and following a positive COVID-19 test result (IRR, 11.00).
“Women being at increased risk is rather a new message,” Dr. Bozkurt said. “But the incidence rate ratios are being compared against the unvaccinated, so when you see the increase in women, it doesn’t mean it’s increased against men. It would be helpful for sex-specific incidence rate ratios to be reported for younger age subgroups, such as ages 16-20 and 20-30, to determine whether there’s an increased risk for males compared to females at younger ages.”
Age and sex differences are huge questions, but “I think we’ll learn a lot about myocarditis in general from what is going to be an explosion of research into the vaccine-associated causes,” Dr. de Lemos said.
“That will help us understand myocarditis more broadly and prepare us for the next generation of vaccines, which inevitably will be mRNA based.”
Dr. Mills reported having no relevant disclosures. Dr. Bozkurt reported consulting for Bayer and scPharmaceuticals and serving on a clinical-events committee for a trial supported by Abbott Pharmaceuticals and on a data and safety monitoring board for a trial supported by Liva Nova Pharmaceuticals. Dr. De Lemos reported having no relevant conflicts of interest.

Advisory on youth mental health crisis gets mixed reviews
The advisory on youth mental health from Surgeon General Vivek Murthy, MD, casts a necessary spotlight on the crisis, clinical psychiatrists say. But some think it could have produced more specifics about funding and payment parity for reimbursement.
The 53-page advisory says that about one in five U.S. children and adolescents aged 3-17 suffer from a mental, emotional, developmental, or behavioral disorder. In the decade before COVID, feelings of sadness and hopelessness, as well as suicidal behaviors, were on the rise. The pandemic has exacerbated symptoms of anxiety, depression, and other mental health issues in young people. Compared with 2019, ED visits in early 2021 for suspected suicide attempts rose 51% in adolescent girls and 4% in boys. “Depressive and anxiety symptoms doubled during the pandemic,” the advisory said.
Scope of the advisory
The advisory, released Dec. 7, covers all sectors and considers all social and policy factors that might be contributing to this crisis, said Jessica (Jessi) Gold, MD, MS, an assistant professor in the department of psychiatry at Washington University, St. Louis.
“It is always possible to reimagine health care to be more patient centered and mental health forward.” But changes of this magnitude take time, Dr. Gold, also director of wellness, engagement, and outreach at the university, said in an interview.
She has seen the impact of the pandemic firsthand in her clinic among students and frontline health care workers aged 18-30. People in that age group “feel everything deeply,” Dr. Gold said. Emotions tied to COVID-19 are just a part of it. Confounding factors, such as climate change, racism, and school shootings all contribute to their overall mental health.
Some children and adolescents with social anxiety have fared better during the pandemic, but those who are part of demographic groups such as racial and ethnic minorities, LGBTQ individuals, low-income youth, and those involved in juvenile justice or welfare systems face a higher risk of mental health challenges, the pandemic notwithstanding.
In her work with schools, Denese Shervington, MD, MPH, has witnessed more mental health challenges related to isolation and separation. “There’s an overall worry about the loss of what used to be, the seeming predictability and certainty of prepandemic life,” said Dr. Shervington, clinical professor of psychiatry at Tulane University, and president and CEO of the Institute for Women and Ethnic Studies, both in New Orleans.
A systems of care plan
The advisory lists actionable items for health care and 10 other industry sectors to improve mental health of children and young adults.
Health care organizations and professionals were advised to take the following six steps:
- Implement trauma-informed care principles and other prevention strategies. This may involve referring patients to resources such as economic and legal supports, school enrichment programs, and educating families on healthy child development in the clinic.
- Routinely screen children for mental health challenges and risk factors such as adverse childhood experiences during primary care well-visits or annual physicals, or at schools or EDs. Primary care physicians should use principles of trauma-informed care to conduct these screenings.
- Screen parents, caregivers, and other family members for depression, intimate partner violence, substance use, and other challenges. These can be done in tandem with broader assessments of social determinants of health such as food or housing insecurity.
- Combine efforts of clinical staff with trusted community partners and child welfare and juvenile justice. Hospital-based violence intervention programs, for example, identify patients at risk of repeat violent injury and refer them to hospital- and community-based resources.
- Build multidisciplinary teams, enlisting children and families to develop services that are tailored to their needs for screening and treatment. Such services should reflect cultural diversity and offered in multiple languages.
- Support the well-being of mental health workers and community leaders to foster their ability to help youth and their families.
Dr. Murthy is talking about a “systems of care” approach, in which all sectors that touch children and youth – not just health care – must work together and do their jobs effectively but collaboratively to address this public health crisis, said Aradhana (Bela) Sood MD, MSHA, FAACAP, senior professor of child mental health policy at Virginia Commonwealth University, Richmond. “An investment in infrastructure support of positive mental health in early childhood, be it in schools, communities, or family well-being will lead to a future where illness is not the result of major preventable societal factors, such as a lack of social supports and trauma.”
Changes will ‘take a lot of buy-in’
The recommendations are actionable in the real world – but there are a lot of them, said Dr. Gold. Dr. Murthy doesn’t specify what the plan is to accomplish these metrics or fund them, she added. He “has money and funders like foundations as steps, but foundations have also suffered in the pandemic, so it is not that simple.” Many of these changes are wide in scope and will take a lot of buy-in.
Dr. Shervington would like to have seen more of a focus on educator well-being, given that young people spend a lot of time in educational settings.
“My organization just completed a study in New Orleans that showed teachers having elevated levels of trauma-based conditions since the pandemic,” she said. Schools are indeed a key place to support holistic mental health by focusing on school climate, Dr. Sood added. “If school administrators became uniformly consistent with recognizing the importance of psychological wellness as a prerequisite of good learning, they will create environments where teachers are keenly aware of a child’s mental wellness and make reduction of bullying, wellness check-ins, [and] school-based mental health clinics a priority.
“These are ways nonmedical, community-based supports can enhance student well-being, and reduce depression and other mental health conditions,” Dr. Sood added.
Child psychiatrists stretched ‘even thinner’
Despite mental health parity rules, health plans have not been held accountable. That failure, combined with excessive demands for prior authorization for mental health treatments “have led to dangerous shortages of psychiatrists able to accept insurance,” said Paul S. Nestadt, MD, an assistant professor and public mental health researcher at Johns Hopkins University, Baltimore.
“This is particularly true for child psychiatrists, who are stretched even thinner than those of us in general practice,” Dr. Nestadt said.
While he doesn’t address it head on, Dr. Murthy uses classic parity language when he states that “mental health is no less important than physical health,” said Dr. Nestadt, who consulted with the surgeon general on developing this advisory. “While many of us would have liked to see parity highlighted more directly, this advisory was designed to be an overview.”
Highlighting social media, gun violence
Dr. Nestadt said he was pleased that the advisory emphasized the importance of restricting access to lethal means in preventing youth suicide.
“With youth suicide rates rising faster than in other age groups, and suicide mortality tied so closely to method availability, the surgeon general made the right choice in highlighting the role of guns in suicide,” he said.
The advisory also discussed the role of media and social media companies in addressing the crisis, which is important, said Dr. Gold.
“I believe very strongly that the way we talk about and portray mental health in the media matters,” she said. “I have seen it matter in the clinic with patients. They’ll wonder if someone will think they are now violent if they are diagnosed with a mental illness. Stories change the narrative.”
While the advisory isn’t perfect, the state of youth mental health “will only get worse if we don’t do something,” noted Dr. Gold. “It is critical that this is validated and discussed at the highest level and messages like Dr. Murthy’s get heard.”
Dr. Gold, Dr. Shervington, and Dr. Sood had no disclosures. Dr. Nestadt disclosed serving as a consultant to the surgeon general advisory.
The advisory on youth mental health from Surgeon General Vivek Murthy, MD, casts a necessary spotlight on the crisis, clinical psychiatrists say. But some think it could have produced more specifics about funding and payment parity for reimbursement.

CDC panel backs mRNA COVID vaccines over J&J because of clot risk
because the Johnson & Johnson shot carries the risk of a rare but potentially fatal side effect that causes blood clots and bleeding in the brain.
In an emergency meeting on December 16, the CDC’s Advisory Committee on Immunization Practices, or ACIP, voted unanimously (15-0) to state a preference for the mRNA vaccines over the Johnson & Johnson shot. The vote came after the panel heard a safety update on cases of thrombosis with thrombocytopenia syndrome, or TTS, a condition that causes large clots that deplete the blood of platelets, resulting in uncontrolled bleeding.
The move brings the United States in line with other wealthy countries. In May, Denmark dropped the Johnson & Johnson shot from its vaccination program because of this risk. Australia and Greece have limited the use of a similar vaccine, made by AstraZeneca, in younger people because of the TTS risk. Both vaccines use the envelope of a different kind of virus, called an adenovirus, to sneak the vaccine instructions into cells. On Dec. 16, health officials said they had determined that TTS was likely due to a class effect, meaning it happens with all adenovirus vector vaccines.
The risk of dying from TTS after a Johnson & Johnson shot is extremely rare. There is an estimated 1 death for every 2 million doses of the vaccine given in the general population. That risk is higher for women ages 30 to 49, rising to about 2 deaths for every 1 million doses given in this age group. There’s no question that the Johnson & Johnson shot has saved many more lives than it has taken, experts said
Still, the committee previously paused the use of the Johnson & Johnson vaccine in April after the first cases of TTS came to light. That pause was lifted just 10 days later, after a new warning was added to the vaccine’s label to raise awareness of the risk.
In updating the safety information on Johnson & Johnson, the panel noted that the warning label had not sufficiently lowered the risk of death from TTS. Doctors seem to be aware of the condition because none of the patients who had developed TTS had been treated with the blood thinner heparin, which can make the syndrome worse. But patients continued to die even after the label was added, the panel noted, because TTS can progress so quickly that doctors simply don’t have time to treat it.
For that reason, and because there are other, safer vaccines available, the panel decided to make what’s called a preferential statement, saying the Pfizer and Moderna mRNA vaccines should be preferred over Johnson & Johnson.
The statement leaves the J&J vaccine on the market and available to patients who are at risk of a severe allergic reaction to the mRNA vaccines. It also means that people can still choose the J&J vaccine if they still want it after being informed about the risks.
About 17 million first doses and 900,000 second doses of the Johnson & Johnson vaccine have been given in the United States. Through the end of August, 54 cases of thrombosis with thrombocytopenia syndrome (TTS) have occurred after the J&J shots in the United States. Nearly half of those were in women ages 30 to 49. There have been nine deaths from TTS after Johnson & Johnson shots.

Telemedicine helps SCD patients survive COVID, but more need access
ATLANTA – , according to an investigator at the annual meeting of the American Society of Hematology.
During the first COVID-19 wave in the summer of 2020, Atlanta’s Grady Sickle Cell Center, the nation’s largest adult sickle cell center, recorded two deaths among the 20 COVID-19_infected patients seen there, said Fuad El Rassi, MD, of Emory University, Atlanta.
Virtual visits, launched to deliver health care needs in the wake of a Georgia’s 2020 statewide shelter-in-place order, helped protect patients from COVID-19 infection, Dr. El Rassi said in a press conference at the meeting.
“The patients’ diligence and awareness to stay home during the pandemic have proven crucial to reducing morbidity and mortality in this vulnerable population,” he said. “The option of having virtual visits for health care delivery was key and should be utilized further in sickle cell care.”
However, virtual visits and other best practices to prevent and treat COVID-19 in patients with sickle cell disease can be challenging to implement outside of large, specialized centers such as Grady.
“The majority of sickle cell patients in major metropolitan areas are not plugged into dedicated sickle cell centers, and that’s a key issue,” said Dr. El Rassi.
“There’s a huge shortage of such clinics around major metropolitan areas, and that restricts things for the general population, unfortunately.”
COVID-19 prevention remains a challenge, no matter where patients are treated. Only about 50% of the center’s sickle cell disease patients are immunized, according to Dr. El Rassi, who added that assessment of vaccine response among those patients is ongoing.
Ifeyinwa (Ify) Osunkwo, MD, MPH, a sickle cell disease specialist, said long-term sustainability of virtual visits depends greatly on states’ continuation of laws or policies that facilitate access to telemedicine. A total of 22 states changed laws or policies during the pandemic to promote access to telemedicine, according to the Commonwealth Fund.
Virtual care is more challenging in states where expanded telemedicine coverage is not available or is ended, said Dr. Osunkwo, director of the Sickle Cell Enterprise at Levine Cancer Institute. The institute is part of Atrium Health, a large health system that operates in four states.
“We are no longer able to do virtual visits for our South Carolinian patients, even though across the border in North Carolina, you can still provide virtual care,” Dr. Osunkwo said in an interview.
“Sickle cell patients suffer from social determinants [of health], so getting to their doctor when they have a regular outpatient visit is kind of hard,” she added. “And having that virtual option actually makes them more adherent, and they have better access to care overall.”
In the study presented at the ASH meeting by Dr. El Rassi and colleagues, there were a total of 55 patients with COVID-19 among the 1,343 sickle cell disease patients they tracked. Of the 55 patients with COVID-19, 28 were female and 27 were male, and 35% were on hydroxyurea for disease modification.
Among these 55 patients with COVID-19, 44 (80%) were hospitalized, and the hospitalizations of 15 (27%) were deemed related to COVID-19 signs and symptoms, Dr. El Rassi said. Twelve of the 55 patients (22%) had emergency visits, including 5 (9%) because of COVID-19 symptoms, he added.
The two deaths from COVID-19 occurred in June and July 2020, said Dr. El Rassi, adding that those patients were among 20 total cases diagnosed from March to September of 2020.
Over the second reported wave of COVID-19, from October 2020 to March 2021, there were no deaths seen among 35 total COVID-19 cases, according to the report at the ASH meeting.
In an interview, Kaitlin Strumph, MD, a sickle cell disease specialist at the Children’s Hospital at Montefiore in New York, noted that patients with sickle cell disease who contract COVID-19 are considered at high risk for morbidity and mortality.
“Patients and providers should not let down their guard,” Dr. Strumph said in an interview. “The best way to protect people from COVID-19 right now is prevention, and vaccinations are the key to further improving outcomes.”
Virtual visits can help bridge gaps in care for patients with sickle cell disease, said Dr. Strumph, given that limited access to care is a large driver of health disparities in this population.
“Telemedicine allows patients to stay home and limit their exposure to COVID-19 out in the community and at the hospital,” she said. “I think most providers feel confident that virtual visits are a huge benefit for the community, and we hope they are here to stay.”

ATLANTA – , according to an investigator at the annual meeting of the American Society of Hematology.
During the first COVID-19 wave in the summer of 2020, Atlanta’s Grady Sickle Cell Center, the nation’s largest adult sickle cell center, recorded two deaths among the 20 COVID-19_infected patients seen there, said Fuad El Rassi, MD, of Emory University, Atlanta.
Virtual visits, launched to deliver health care needs in the wake of a Georgia’s 2020 statewide shelter-in-place order, helped protect patients from COVID-19 infection, Dr. El Rassi said in a press conference at the meeting.
“The patients’ diligence and awareness to stay home during the pandemic have proven crucial to reducing morbidity and mortality in this vulnerable population,” he said. “The option of having virtual visits for health care delivery was key and should be utilized further in sickle cell care.”
However, virtual visits and other best practices to prevent and treat COVID-19 in patients with sickle cell disease can be challenging to implement outside of large, specialized centers such as Grady.
“The majority of sickle cell patients in major metropolitan areas are not plugged into dedicated sickle cell centers, and that’s a key issue,” said Dr. El Rassi.
“There’s a huge shortage of such clinics around major metropolitan areas, and that restricts things for the general population, unfortunately.”
COVID-19 prevention remains a challenge, no matter where patients are treated. Only about 50% of the center’s sickle cell disease patients are immunized, according to Dr. El Rassi, who added that assessment of vaccine response among those patients is ongoing.
Ifeyinwa (Ify) Osunkwo, MD, MPH, a sickle cell disease specialist, said long-term sustainability of virtual visits depends greatly on states’ continuation of laws or policies that facilitate access to telemedicine. A total of 22 states changed laws or policies during the pandemic to promote access to telemedicine, according to the Commonwealth Fund.
Virtual care is more challenging in states where expanded telemedicine coverage is not available or is ended, said Dr. Osunkwo, director of the Sickle Cell Enterprise at Levine Cancer Institute. The institute is part of Atrium Health, a large health system that operates in four states.
“We are no longer able to do virtual visits for our South Carolinian patients, even though across the border in North Carolina, you can still provide virtual care,” Dr. Osunkwo said in an interview.
“Sickle cell patients suffer from social determinants [of health], so getting to their doctor when they have a regular outpatient visit is kind of hard,” she added. “And having that virtual option actually makes them more adherent, and they have better access to care overall.”
In the study presented at the ASH meeting by Dr. El Rassi and colleagues, there were a total of 55 patients with COVID-19 among the 1,343 sickle cell disease patients they tracked. Of the 55 patients with COVID-19, 28 were female and 27 were male, and 35% were on hydroxyurea for disease modification.
Among these 55 patients with COVID-19, 44 (80%) were hospitalized, and the hospitalizations of 15 (27%) were deemed related to COVID-19 signs and symptoms, Dr. El Rassi said. Twelve of the 55 patients (22%) had emergency visits, including 5 (9%) because of COVID-19 symptoms, he added.

FDA updates risks, cautions for clotting-bleeding disorder on Janssen COVID-19 vaccine
Updated Janssen/Johnson & Johnson COVID-19 vaccine fact sheets for health care professionals and the general public now include a contraindication to its use in persons with a history of thrombosis with thrombocytopenia after receiving it “or any other adenovirus-vectored COVID-19 vaccine,” the U.S. Food and Drug Administration has announced.
Thrombosis with thrombocytopenia syndrome (TTS) – thrombocytopenia and increased bleeding risk along with documented thrombosis – after administration of the Janssen Ad26.COV2.S vaccine remains rare. But over all age groups, about one in seven cases have been fatal, said the agency.
the provider fact sheet states.
Although TTS associated with the Janssen COVID-19 vaccine has been reported in men and women aged 18 and older, the highest reported rate has been for women aged 30-49, the agency states. The rate in that group has been about 1 case per 100,000 doses administered.
Symptoms of TTS may occur 1-2 weeks after administration of the Janssen COVID-19 vaccine, the FDA says, based on data from the Vaccine Adverse Events Reporting System (VAERS).
Its clinical course shares features with autoimmune heparin-induced thrombocytopenia. In individuals with suspected TTS following receipt of the Janssen COVID-19 vaccine, the agency cautions, the use of heparin “may be harmful and alternative treatments may be needed. Consultation with hematology specialists is strongly recommended.”
The apparent excess risk of TTS remains under investigation, but “the FDA continues to find that the known and potential benefits of the Janssen COVID-19 vaccine outweigh its known and potential risks in individuals 18 years of age and older,” the agency states.

A pandemic silver lining? Dramatic drop in teen drug use
Illicit drug use among U.S. teenagers dropped sharply in 2021, likely because of stay-at-home orders and other restrictions on social activities due to the COVID-19 pandemic.
The latest findings, from the Monitoring the Future survey, represent the largest 1-year decrease in overall illicit drug use reported since the survey began in 1975.
“We have never seen such dramatic decreases in drug use among teens in just a 1-year period,” Nora Volkow, MD, director of the National Institute on Drug Abuse (NIDA), said in a news release.
“These data are unprecedented and highlight one unexpected potential consequence of the COVID-19 pandemic, which caused seismic shifts in the day-to-day lives of adolescents,” said Dr. Volkow.
The annual Monitoring the Future survey is conducted by researchers at the University of Michigan, Ann Arbor, and funded by NIDA, to assess drug and alcohol use and related attitudes among adolescent students across the United States.
This year’s self-reported survey included 32,260 students in grades 8, 10, and 12 across 319 public and private schools.
Compared with 2020, the percentage of students reporting any illicit drug use (other than marijuana) in 2021 decreased significantly for 8th graders (down 5.4%), 10th graders (down 11.7%), and 12th graders (down 4.8%).
For alcohol, about 47% of 12th graders and 29% of 10th graders said they drank alcohol in 2021, down significantly from 55% and 41%, respectively, in 2020. The percentage of 8th graders who said they drank alcohol remained stable (17% in 2021 and 20% in 2020).
For teen vaping, about 27% of 12th graders and 20% of 10th graders said they had vaped nicotine in 2021, down significantly from nearly 35% and 31%, respectively, in 2020. Fewer 8th graders also vaped nicotine in 2021 compared with 2020 (12% vs. 17%).
For marijuana, use dropped significantly for all three grades in 2021 compared with 2020. About 31% of 12th graders and 17% of 10th graders said they used marijuana in 2021, down from 35% and 28% in 2020. Among 8th graders, 7% used marijuana in 2021, down from 11% in 2020.
The latest survey also shows significant declines in use of a range of other drugs for many of the age cohorts, including cocaine, hallucinogens, and nonmedical use of amphetamines, tranquilizers, and prescription opioids.
“We knew that this year’s data would illuminate how the COVID-19 pandemic may have impacted substance use among young people, and in the coming years, we will find out whether those impacts are long-lasting as we continue tracking the drug use patterns of these unique cohorts of adolescents,” Richard A. Miech, PhD, who heads the Monitoring the Future study at the University of Michigan, said in the news release.
“Moving forward, it will be crucial to identify the pivotal elements of this past year that contributed to decreased drug use – whether related to drug availability, family involvement, differences in peer pressure, or other factors – and harness them to inform future prevention efforts,” Dr. Volkow added.
In 2021, students across all age groups reported moderate increases in feelings of boredom, anxiety, depression, loneliness, worry, difficulty sleeping, and other negative mental health indicators since the beginning of the pandemic.

Even COVID-19 can’t stop a true optimist
Squeezing a little lemonade out of COVID-19
We like to think of ourselves as optimists here at LOTME. A glass is half full, the sky is partly sunny, and our motto is “Always look on the bright side of insanity.” Then again, our motto before that was “LOTME: Where science meets stupid,” so what do we know?
Anyway, it’s that upbeat, can-do attitude that allows us to say something positive – two somethings, actually – about the insanity that is COVID-19.
Our journey to the bright side begins, oddly enough, in the courtroom. Seems that our old friend, the face mask, is something of a lie-detector aid for juries. The authors of a recent literature review of studies on deception “found that facial expressions and other forms of nonverbal behaviour are an unreliable indicator of deceit,” according to a statement from the University of Portsmouth, where the analysis was conducted.
The one study that directly examined the role of face coverings in court proceedings showed that, “by taking away the distraction of nonverbal behaviours, observers had to rely on speech content, which turned out to be better for detecting lies,” the university said.
The second stage of our positivity trek brings us to the National Trends in Disability Employment monthly update, where we see a fourth consecutive month of gains for people with disabilities despite the larger trend of declines among those without disabilities.
Here are some numbers from the Kessler Foundation and the University of New Hampshire’s Institute on Disability to tell the story: From October to November, the employment-to-population ratio increased 4.2% for working-age people with disabilities, compared with 0.4% for people without disabilities. At the same time, the labor force participation rate rose 2.4% for working-age people with disabilities and just 0.1% for working-age people without disabilities.
Both indicators surpassed their historic highs, Andrew Houtenville, PhD, director of the Institute on Disability, said in the update. “These gains suggest that the restructuring resulting from the pandemic may be benefiting people with disabilities. Ironically, it may have taken a pandemic to shake the labor market loose for people with disabilities.”
And that is how a world-class optimist turns one gigantic lemon into lemonade.
Cut the cheese for better sleep
So, we’ve already talked about the TikTok lettuce tea hack that’s supposed to help us sleep better. Well, there’s another food that could have the opposite effect.
According to an article from the BBC, cheese has something of a reputation. Ever since the 1960s, when a researcher noted that one patient’s nightmares stopped after he quit eating an ounce or two of cheddar each night, there’s been speculation that cheese gives you weird dreams. Another study in 2005 suggested certain types of cheese cause certain types of dreams. Blue cheese for vivid dreams and cheddar cheese for celebrity cameos.
But is there any truth to it at all?
Regardless of what we eat, going to bed hungry could cause vivid dreams, according to research by Tore Nielsen, director of the University of Montreal’s dream and nightmare lab. The 2015 study showed that high lactose could have an effect on dreams.
In that study, 17% of participants said their dreams were influenced by what they ate, but the kicker was that dairy products were the foods most reported as causing the weird dreams, the BBC noted.
“It’s likely an indirect effect in that lactose produces symptoms like gas, bloating and diarrhoea and influences dreams, as dreams draw on somatic sources like this. And if you have certain kinds of intolerances, you still may be likely to eat those foods sometimes,” Mr. Nielsen told the BBC.
There’s also the theory that it’s all in the timing of consumption. Are you the type of person to sneak a slice of cheese from the fridge late at night? (Nods.) Same.
“One reason cheese and nightmares come about is that eating later before bed is more likely to disrupt sleep, and cheese can be hard to digest,” said Charlotte Gupta, a research fellow at Central Queensland University in Australia and a coauthor of a 2020 review on how diet affects our sleep.
So as tempting as it is, maybe skip sprinkling Parmesan cheese shreds into your mouth at the open fridge before bed.
Teeing up against Parkinson’s
For the nearly 1 million people in the United States with Parkinson’s disease, tai chi is one of the best ways to alleviate the symptoms. The average Parkinson’s patient, however, is going to be on the older side and more likely to view the martial art as some sort of communist plot. And would you participate in a communist plot? We don’t think so.
One group of researchers saw that patients weren’t keeping up with their therapy and decided to try a different activity, something that older people would be more likely to stick with. Something a bit more stereotypical. No, not shuffleboard. They tried golf.
“Golf is popular – the most popular sport for people over the age of 55 – which might encourage people to try it and stick with it,” study author Anne-Marie A. Wills, MD, of Massachusetts General Hospital, Boston, said in a Study Finds report.
In a small study, the investigators had a group of patients with Parkinson’s regularly go to a driving range for 10 weeks to hit golf balls (all expenses paid too, and that’s a big deal for golf), while another group continued with their tai chi.
At the end of the study, the 8 patients who went to the driving range had significantly better results in a Parkinson’s mobility test than those of the 12 patients in the tai chi group. In addition, the golf-group participants said they were more likely to continue with their therapy than were those who did tai chi.
Despite the small size of the study, the research team said the results certainly warrant further research. After all, the best sort of therapy is the kind that actually gets done. And golf just gets in your head. The eternal quest to add distance, to straighten out that annoying slice, to stop thinning half your chips, to make those annoying 4-footers. ... Maybe that’s just us.

Both indicators surpassed their historic highs, Andrew Houtenville, PhD, director of the Institute on Disability, said in the update. “These gains suggest that the restructuring resulting from the pandemic may be benefiting people with disabilities. Ironically, it may have taken a pandemic to shake the labor market loose for people with disabilities.”
And that is how a world-class optimist turns one gigantic lemon into lemonade.
Cut the cheese for better sleep
So, we’ve already talked about the TikTok lettuce tea hack that’s supposed to help us sleep better. Well, there’s another food that could have the opposite effect.
According to an article from the BBC, cheese has something of a reputation. Ever since the 1960s, when a researcher noted that one patient’s nightmares stopped after he quit eating an ounce or two of cheddar each night, there’s been speculation that cheese gives you weird dreams. Another study in 2005 suggested certain types of cheese cause certain types of dreams. Blue cheese for vivid dreams and cheddar cheese for celebrity cameos.
But is there any truth to it at all?
Regardless of what we eat, going to bed hungry could cause vivid dreams, according to research by Tore Nielsen, director of the University of Montreal’s dream and nightmare lab. The 2015 study showed that high lactose could have an effect on dreams.
In that study, 17% of participants said their dreams were influenced by what they ate, but the kicker was that dairy products were the foods most reported as causing the weird dreams, the BBC noted.
“It’s likely an indirect effect in that lactose produces symptoms like gas, bloating and diarrhoea and influences dreams, as dreams draw on somatic sources like this. And if you have certain kinds of intolerances, you still may be likely to eat those foods sometimes,” Mr. Nielsen told the BBC.
There’s also the theory that it’s all in the timing of consumption. Are you the type of person to sneak a slice of cheese from the fridge late at night? (Nods.) Same.
“One reason cheese and nightmares come about is that eating later before bed is more likely to disrupt sleep, and cheese can be hard to digest,” said Charlotte Gupta, a research fellow at Central Queensland University in Australia and a coauthor of a 2020 review on how diet affects our sleep.
So as tempting as it is, maybe skip sprinkling Parmesan cheese shreds into your mouth at the open fridge before bed.
Teeing up against Parkinson’s
For the nearly 1 million people in the United States with Parkinson’s disease, tai chi is one of the best ways to alleviate the symptoms. The average Parkinson’s patient, however, is going to be on the older side and more likely to view the martial art as some sort of communist plot. And would you participate in a communist plot? We don’t think so.
One group of researchers saw that patients weren’t keeping up with their therapy and decided to try a different activity, something that older people would be more likely to stick with. Something a bit more stereotypical. No, not shuffleboard. They tried golf.
“Golf is popular – the most popular sport for people over the age of 55 – which might encourage people to try it and stick with it,” study author Anne-Marie A. Wills, MD, of Massachusetts General Hospital, Boston, said in a Study Finds report.
In a small study, the investigators had a group of patients with Parkinson’s regularly go to a driving range for 10 weeks to hit golf balls (all expenses paid too, and that’s a big deal for golf), while another group continued with their tai chi.
At the end of the study, the 8 patients who went to the driving range had significantly better results in a Parkinson’s mobility test than those of the 12 patients in the tai chi group. In addition, the golf-group participants said they were more likely to continue with their therapy than were those who did tai chi.
Despite the small size of the study, the research team said the results certainly warrant further research. After all, the best sort of therapy is the kind that actually gets done. And golf just gets in your head. The eternal quest to add distance, to straighten out that annoying slice, to stop thinning half your chips, to make those annoying 4-footers. ... Maybe that’s just us.
Squeezing a little lemonade out of COVID-19
We like to think of ourselves as optimists here at LOTME. A glass is half full, the sky is partly sunny, and our motto is “Always look on the bright side of insanity.” Then again, our motto before that was “LOTME: Where science meets stupid,” so what do we know?
Anyway, it’s that upbeat, can-do attitude that allows us to say something positive – two somethings, actually – about the insanity that is COVID-19.
Our journey to the bright side begins, oddly enough, in the courtroom. Seems that our old friend, the face mask, is something of a lie-detector aid for juries. The authors of a recent literature review of studies on deception “found that facial expressions and other forms of nonverbal behaviour are an unreliable indicator of deceit,” according to a statement from the University of Portsmouth, where the analysis was conducted.
The one study that directly examined the role of face coverings in court proceedings showed that, “by taking away the distraction of nonverbal behaviours, observers had to rely on speech content, which turned out to be better for detecting lies,” the university said.
The second stage of our positivity trek brings us to the National Trends in Disability Employment monthly update, where we see a fourth consecutive month of gains for people with disabilities despite the larger trend of declines among those without disabilities.
Here are some numbers from the Kessler Foundation and the University of New Hampshire’s Institute on Disability to tell the story: From October to November, the employment-to-population ratio increased 4.2% for working-age people with disabilities, compared with 0.4% for people without disabilities.

COVID-19 asymptomatic infection rate remains high
Based on data from a meta-analysis of 95 studies that included nearly 30,000,000 individuals, the pooled percentage of asymptomatic COVID-19 infections was 0.25% in the tested population and 40.5% among confirmed cases.
, wrote Qiuyue Ma, PhD, and colleagues of Peking University, Beijing.
In a study published in JAMA Network Open the researchers identified 44 cross-sectional studies, 41 cohort studies, seven case series, and three case series on transmission studies. A total of 74 studies were conducted in developed countries, including those in Europe, North America, and Asia. Approximately one-third (37) of the studies were conducted among health care workers or in-hospital patients, 17 among nursing home staff or residents, and 14 among community residents. In addition, 13 studies involved pregnant women, eight involved air or cruise ship travelers, and six involved close contacts of individuals with confirmed infections.
The meta-analysis included 29,776,306 tested individuals; 11,516 of them had asymptomatic infections.
Overall, the pooled percentage of asymptomatic infections among the tested population was 0.25%. In an analysis of different study populations, the percentage was higher in nursing home residents or staff (4.52%), air or cruise ship travelers (2.02%), and pregnant women (2.34%), compared against the pooled percentage.
The pooled percentage of asymptomatic infections among the confirmed population was 40.50%, and this percentage was higher in pregnant women (54.11%), air or cruise ship travelers (52.91%), and nursing home residents or staff (47.53%).
The pooled percentage in the tested population was higher than the overall percentage when the mean age of the study population was 60 years or older (3.69%). By contrast, in the confirmed population, the pooled percentage was higher than the overall percentage when the study population was younger than 20 years (60.2%) or aged 20 to 39 years (49.5%).
The researchers noted in their discussion that the varying percentage of asymptomatic individuals according to community prevalence might impact the heterogeneity of the included studies. They also noted the high number of studies conducted in nursing home populations, groups in which asymptomatic individuals were more likely to be tested.
The study findings were limited by several factors, including the potential for missed studies that were not published at the time of the meta-analysis, as well as the exclusion of studies written in Chinese, the researchers noted. Other limitations included lack of follow-up on presymptomatic and covert infections, and the focus on specific populations, factors that may limit the degree to which the results can be generalized.
However, the results highlight the need to screen for asymptomatic infections, especially in countries where COVID-19 has been better controlled, the researchers said. Management strategies for asymptomatic infections, when identified, should include isolation and contact tracing similar to strategies used with confirmed cases, they added.
More testing needed to catch cases early
“During the initial phase of [the] COVID-19 pandemic, testing was not widely available in the United States or the rest of the world,” Setu Patolia, MD, of Saint Louis University School of Medicine, Missouri, said in an interview. Much of the world still lacks access to COVID-19 testing, and early in the pandemic only severely symptomatic patients were tested, he said. “With new variants, particularly the Omicron variant, which may have mild or minimally symptomatic disease, asymptomatic carriers play an important role in propagation of the pandemic,” he explained. “It is important to know the asymptomatic carrier rate among the general population for the future control of [the] pandemic,” he added.
Dr. Patolia said he was surprised by the study finding that one in 400 people in the general population could be asymptomatic carriers of COVID-19.
“Also, nursing home patients are more at risk of complications of COVID, and I expected that they would have a higher rate of symptomatic disease as compared to [the] general population,” said Dr. Patolia. He was also surprised by the high rate of asymptomatic infections in travelers.
“Physicians should be more aware about the asymptomatic carrier rate, particularly in travelers and nursing home patients,” he noted. “Travelers carry high risk of transferring infection from one region to another region of the world, and physicians should advise them to get tested despite the absence of symptoms,” Dr. Patolia emphasized. “Similarly, once any nursing home patient has been diagnosed with COVID-19, physicians should be more careful with the rest of the nursing home patients and test them despite the absence of the symptoms,” he added.
Dr. Patolia also recommended that pregnant women wear masks to help prevent disease transmission when visiting a doctor’s office or labor unit.
Looking ahead, there is a need for cheaper at-home testing kits so that all vulnerable populations can be tested fast and frequently, Dr. Patolia said.
The study was supported by the National Natural Science Foundation of China. The researchers had no financial conflicts to disclose. Dr. Patolia has disclosed no relevant financial relationships.

Children and COVID: Weekly cases resume their climb
After a brief lull in activity, weekly COVID-19 cases in children returned to the upward trend that began in early November, based on data from the American Academy of Pediatrics and the Children’s Hospital Association.
according to the Centers for Disease Control and Prevention.
New COVID-19 cases were up by 23.5% for the week of Dec. 3-9, after a 2-week period that saw a drop and then just a slight increase, the AAP and CHA said in their latest weekly COVID report. There were 164,000 new cases from Dec. 3 to Dec. 9 in 46 states (Alabama, Nebraska, and Texas stopped reporting over the summer of 2021 and New York has never reported by age), the District of Columbia, New York City, Puerto Rico, and Guam.
The increase occurred across all four regions of the country, but the largest share came in the Midwest, with over 65,000 new cases, followed by the West (just over 35,000), the Northeast (just under 35,000), and the South (close to 28,000), the AAP/CHA data show.
The 7.2 million cumulative cases in children as of Dec. 9 represent 17.2% of all cases reported in the United States since the start of the pandemic, with available state reports showing that proportion ranges from 12.3% in Florida to 26.1% in Vermont. Alaska has the highest incidence of COVID at 19,000 cases per 100,000 children, and Hawaii has the lowest (5,300 per 100,000) among the states currently reporting, the AAP and CHA said.
State reporting on vaccinations shows that 37% of children aged 5-11 years in Massachusetts have received at least one dose, the highest of any state, while West Virginia is lowest at just 4%. The highest vaccination rate for children aged 12-17 goes to Massachusetts at 84%, with Wyoming lowest at 37%, the AAP said in a separate report.
Nationally, new vaccinations fell by a third during the week of Dec. 7-13, compared with the previous week, with the largest decline (34.7%) coming from the 5- to 11-year-olds, who still represented the majority (almost 84%) of the 430,000 new child vaccinations received, according to the CDC’s COVID Data Tracker. Corresponding declines for the last week were 27.5% for 12- to 15-year-olds and 22.7% for those aged 16-17.
Altogether, 21.2 million children aged 5-17 had received at least one dose and 16.0 million were fully vaccinated as of Dec. 13. By age group, 19.2% of children aged 5-11 years have gotten at least one dose and 9.6% are fully vaccinated, compared with 62.1% and 52.3%, respectively, among children aged 12-17, the CDC said.
