Researchers examine unintentional drug overdose mortality in Years of Life Lost among adolescents

In a first-ever study, researchers at The Ohio State University Wexner Medical Center and College of Medicine examined the unintentional drug overdose mortality in Years of Life Lost among adolescents and young people in the United States.

New toolkit helps practitioners to deliver effective remote assessments for people with physical impairments

Appointments for people with physical impairments were quickly made remote during the pandemic – with a lack of consistency or guidance around what could take place remotely and what would need to wait for an in-person visit.

Drugs derived from activated protein C may limit ischemia and reperfusion injury, study suggests

A University of South Florida Health preclinical study offers molecular insight into how activated protein C (APC) may improve aging patients' tolerance to reperfusion injury – a potentially adverse effect of treatment for ischemic heart disease.

States were sharing covid test kits. Then omicron hit.

In a few short months, states have gone from donating surplus rapid covid-19 tests to states with shortages to hoarding them as demand driven by the spike in cases strains supplies.

It’s Day 6 of covid, and a rapid antigen test comes back positive. stay home, say virologists.

What does it mean if a person's rapid antigen test result comes back positive after five days of isolation due to covid-19? According to the experts, that person is most likely still carrying a viral load high enough to infect others.

In California nursing homes, omicron is bad, but so is the isolation

Dina Halperin had been cooped up alone for three weeks in her nursing home room after her two unvaccinated roommates were moved out at the onset of the omicron surge. "I'm frustrated," she said, "and so many of the nursing staff are burned out or just plain tired."

Accurate prediction of COVID-19 outbreaks using location data from mobile devices

Researchers at the Yale School of Public Health were able to accurately predict outbreaks of COVID-19 in Connecticut municipalities using anonymous location information from mobile devices, according to a new study published in Science Advances.

Estimating the impending endemic seasonality of SARS-CoV-2 in global population centers

A new study uses long-term data on the incidence of circulating coronaviruses and estimates the endemic seasonality of SARS-CoV-2 in global population centers.

Immunity based upon “mild" Omicron infection is weak for Omicron reinfection

Researchers evaluate antibody responses in vaccinated individuals who subsequently developed Delta and Omicron SARS-CoV-2 breakthrough infections.

Using lateral flow testing to define COVID-19 self-isolation period

A recent study discusses the role of lateral flow device testing in potentially improving COVID-19 isolation policies.

Researchers develop a real-time method for projecting COVID-19 quarantine housing needs

It's difficult to plan ahead when SARS-CoV-2, the virus that causes COVID-19, is so unpredictable. But, there is now a straightforward method for predicting one of the resources needed to slow the spread of COVID-19 in communities.

A synthesis of evidence sheds light on major immune components and mechanisms involved in COVID-19

New research highlights principal host factors that may explain the immune responses to SARS-CoV-2 and its variants in the context of infection susceptibility, disease severity, and previous immunity.

Evidence on intra-host recombination of SARS-CoV-2 during superinfection by Alpha and Epsilon variants in USA

A new study captured an instance of SARS-CoV-2 superinfection in an individual, simultaneously infected by two SARS-CoV-2 variants, Alpha and Epsilon during the second COVID-19 wave in New York City in early 2021.

In super-vaxxed Vermont, covid strikes — but packs far less punch

Even Eden, a snow-covered paradise in northern Vermont, is poisoned by omicron.

Airborne SARS-CoV-2 transmission beyond home isolation rooms may pose infection risk to others

A Rutgers study has detected tiny airborne particles containing RNA from the SARS-CoV-2 that causes COVID-19, both inside and outside of the rooms in which infected people were self-isolating at home. This finding suggests that airborne transmission beyond the isolation rooms in homes may pose a risk of infection to other home occupants.

Bisphenol A's effects are much worse than previously thought, experts say

The Endocrine Society joined a coalition of physicians, scientists and public health and environmental organizations to send a formal petition to the Food and Drug Administration (FDA), calling on the agency to rescind its approvals for bisphenol A (BPA) in adhesives and coatings and set strict limits on its use in plastics that contact food.

Desipramine and L-cycloserine together reduce ceramide levels in the retina and enhance vision

Researchers from the University of California, Irvine have discovered that the absence of Adiponectin receptor 1 protein (AdipoR1), one of the principal enzymes regulating ceramide homeostasis in the retina, leads to an accumulation of ceramides in the retina, resulting in progressive photoreceptor cell death and ultimately vision loss.

Banning tobacco products leads to a 4% decline in gross sales, finds study

New research in the INFORMS journal Marketing Science shows that doing something positive for public health can be costly. The researchers say that banning tobacco products means retailers may see as much as a 4% decline in gross sales.
