Muscle strength associated with reduced COVID-19 hospitalization in older adults

Exercising more than once a week after 50 years of age is linked to a 60% lower risk of COVID-19 hospitalization. An international team of researchers has found that physical activity involving muscle training can be protective against severe infection.

Study: Semaglutide drug promotes weight loss in patients with type 2 diabetes

Patients with type 2 diabetes that were treated with a weekly injection of the breakthrough drug Semaglutide were able to achieve an average weight loss of nearly 10kg, according to a new study published in The Lancet today.

Placebo-like effects may explain the benefits of psychedelic drugs

Positive psychological effects associated with taking small doses of psychedelic drugs are likely the result of users' expectations, suggests a study published today in eLife.

New tool can define how infectious pathogens transport in the air

In the 1995 movie "Outbreak," Dustin Hoffman's character realizes, with appropriately dramatic horror, that an infectious virus is "airborne" because it's found to be spreading through hospital vents.

Aircraft cabins may have lowest levels of aerosol particles, show’s study

If you're looking for an indoor space with a low level of particulate air pollution, a commercial airliner flying at cruising altitude maybe your best option.

Newly developed maps show how human brains are kept nourished

Our brains are non-stop consumers. A labyrinth of blood vessels, stacked end-to-end comparable in length to the distance from San Diego to Berkeley, ensures a continuous flow of oxygen and sugar to keep our brains functioning at peak levels.

COVID-19 disrupts heart muscle contraction, may lead to heart failure

Since early in the pandemic, COVID-19 has been associated with heart problems, including reduced ability to pump blood and abnormal heart rhythms.

Some types of fat are more resistant to weight loss, shows study

Scientists have mapped out what happens to fat deposits during intermittent fasting (every second day), with an unexpected discovery that some types of fat are more resistant to weight loss.

How SARS-CoV-2 proteins affect vascular functionality

The study, published on the pre-print server medRxiv, can pinpoint and isolate how each of the SARS-CoV-2 proteins independently affects the endothelial response and directly gauge endothelial functionality.

Study demonstrates long-term neuropsychological consequences following SARS-CoV-2 infection

The study, published in the pre-print server medRxiv, demonstrates the presence of long-lasting neuropsychological sequelae after COVID-19, regardless of the respiratory disease's severity.

SARS-CoV-2 viremia predicts severe COVID-19 disease outcomes

The SARS-CoV-2 plasma viremia has been linked to severe disease and death in COVID-19 cases in small-scale cohort studies. The current study, published on the pre-print server medRxiv, aimed to study the mechanisms behind this relationship.

Early antibody response predicts COVID-19 outcome

To address this gap, researchers from the U.S. evaluated the timing of antibody production against SARS-CoV-2 in hospitalized patients. They used a highly sensitive multiplexed bead-based immunoassay that allows for early detection of anti-SARS-CoV-2 antibodies. The study is published on the preprint server medRxiv.

Quantifying SARS-CoV-2 viral load in hospitalized patients

A new paper, published on the medRxiv preprint server, investigates the role of subgenomic RNA transcripts in SARS-CoV-2 infection. Earlier, scientists believed that subgenomic RNA could be traceable infective markers to monitor infectivity.

A model of vaccine-derived herd immunity against COVID-19 in heterogeneous populations

A recent theoretical paper, currently available on the medRxiv preprint server, unveils a novel vaccination model that shows how a herd immunity threshold (HIT) value which considers heterogeneity is substantially lower in comparison with a HIT value of assuming a homogeneous population – with many implications for further vaccination planning.

Concerning mutation in New York SARS-CoV-2 should be monitored, warn researchers

Researchers at the New York State Department of Health in the United States have said concerning mutations within the B.1.526 lineage of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has recently become prevalent in New York State warrant further monitoring.

Survey reveals impact of Pfizer-BioNTech vaccination in the UK

Researchers at Imperial College London in the UK have reported on round five of the REal-time Assessment of Community Transmission-2 (REACT-2) program – a cross-sectional community survey measuring the prevalence of antibodies against the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among adults in England.

Child abuse cases may have declined during the pandemic, study shows

While natural disasters and economic recessions traditionally unleash an uptick in child abuse, a new study suggests that cases may have declined in the first months of the pandemic, compared with the same timeframe in previous years.

Study: The pandemic has worsened the condition of 70% of people with chronic pain

The pandemic has impacted significantly on people who suffer chronic pain. A study performed by the eHealth Lab, a research group affiliated with the Faculty of Health Sciences and the Universitat Oberta de Catalunya's eHealth Center, has shown that 70% of the people with chronic pain have seen their condition worsen in terms of severity, frequency of episodes and interference in their daily activities.

Children with MIS-C have highly activated immune systems, study finds

Taking the first deep dive into how the immune system is behaving in patients with multisystem inflammatory syndrome in children (MIS-C), researchers at Children's Hospital of Philadelphia and the Perelman School of Medicine at the University of Pennsylvania have found that children with this condition have highly activated immune systems that, in many ways, are more similar to those of adults with severe COVID-19.
