“After proper evaluation, manufacturers of rapid antigen tests should consider extending their instructions for use to include combined oropharyngeal and nasal self-sampling,” they propose.Ī research letter in the New England Journal of Medicine suggests that autoantibodies towards the interleukin-1 receptor antagonist (IL-1Ra) may explain why some people develop myocarditis after COVID-19 vaccination. The addition of oropharyngeal swabbing, from the back of the throat, improved diagnostics, investigators noted. Īmid growing skepticism of the ability of at-home rapid antigen tests to track infections and transmissions, a Dutch study in the BMJ shows that the sensitivity of “unsupervised self-sampling” in people with symptoms of COVID-19, using three different antigen tests, decreased during the Omicron period. “The vast majority of young people who get COVID-19 will not go on to develop type 1 diabetes, but it is important that clinicians and parents are aware of the signs and symptoms,” the lead author on the latter paper, Hanne Løvdal Gulsethm, MD, PhD, is quoted in a press release. A second study, presented last weekend at the European Association for the Study of Diabetes Annual Meeting, showed that the risk of developing type 1 diabetes among Norwegian youth increased from 0.08% in those who’d earlier tested negative for COVID-19 to 0.13% among those who’d tested positive. One study in JAMA Network Open, using deidentified data from a global collection of electronic health records, points to a roughly twofold higher risk of new-onset type 1 diabetes at 1, 3, and 6 months after COVID-19 infection in pediatric patients as compared with those with non-COVID infections.
There’s more evidence linking SARS-CoV-2 infection to increasing rates of type 1 diabetes in children and adolescents. According to Jennifer Radin, PhD, and colleagues, participants’ daily resting heart rate and step count can be used to identify any “anomalous sensor days, in which resting heart rate was higher than, and step count was lower than, a specified threshold calculated for each individual by use of their baseline data.” Their study describes the development cohort and a validation cohort in which data extracted from digital sources correlated significantly not only with real-time COVID-19 averages reported by the CDC, but also with predicted cases 6 and 12 days in the future. Researchers writing in the Lancet Digital Health are making the case for using “passively collected sensor data” from smartwatches and Fitbits to track and forecast COVID-19 case counts in real time. Other countries, including the Netherlands as of September 17, have made similar recent announcements, while Hong Kong, effective today, has eliminated its quarantine policy for incoming international travelers, although mandatory testing and some restrictions on movement remain in place. “The change is one of the final sets of revisions to overhaul recommendations for COVID-19 since August.”Ĭanada, meanwhile, announced today that it will be dropping all COVID-19 border requirements, including mandatory vaccines, masks on planes and trains, and the need to fill out digital health information prior to arrival in the country as of October 1. In the United States, the Centers for Disease Control and Prevention (CDC) has dropped its requirement for universal masking among healthcare workers “after a weeklong slowdown in COVID-19 hospitalizations and nursing home infections worldwide,” writes Mariah Taylor in Becker’s Hospital Review, citing CBS news as the source. “As it gets colder and we head towards winter, we will start to see respiratory infections pick up-please try to stay at home if you are unwell and avoid contact with vulnerable people.” “All of the available boosters provide good protection against severe illness from COVID-19 and getting your booster sooner rather than later is crucial,” Susan Hopkins, MB BCh, chief medical advisor at the UK Health Security Agency, is quoted. We hope the Dispatch has proved useful to people trying to stay abreast of the research and policy news in this space.ĬOVID-19 hospitalizations are rising in England for the first time since early summer, the Guardian notes, citing the government’s coronavirus dashboard. Today’s Dispatch will be our last: we will continue to cover any SARS-CoV-2 news as it pertains to cardiology care. We’ve decided to press pause on TCTMD’s COVID-19 Dispatch, recognizing that though the pandemic is not yet over, it has entered a different phase, our readership has a wealth of other sources of information, and our primary focus is cardiovascular disease.
