Body mass index and severe COVID-19

French researchers led by first author Abdallah Al-Salameh from the Department of Endocrinology, Diabetes Mellitus and Nutrition, Amiens University Hospital, Amiens, France, have published findings of their study titled, “The association between body mass index class and coronavirus disease 2019 outcomes,” in the latest issue of the International Journal of Obesity.

Researchers develop synthetic defective SARS-CoV-2 genome that inhibits viral replication

A shorter genome comprising only a part of the SARS-CoV-2's RNA genome competes with the normal virus for growth and can potentially prevent viral replication.

Antihypertensive drugs may reduce COVID-19 mortality in at-risk patients

A new multicenter study that recently appeared on the medRxiv* preprint server in November 2020 has found a lower or equal risk of fatal COVID-19 in hypertensive patients, depending on the type of medication they are on.

Getting adequate sleep may help teens with migraines

Research indicates that starting school later in the morning yields health and academic benefits for high schoolers, whose natural body clock tends toward late-to-bed, late-to-rise habits.

Study shows how high frequency sound waves could revolutionize ultrasound-driven chemistry

Researchers have revealed how high-frequency sound waves can be used to build new materials, make smart nanoparticles and even deliver drugs to the lungs for painless, needle-free vaccinations.

Dynamic interplay of brain wave frequencies may guide humans in highlighting surprises

If you open your office door one morning and there is a new package waiting on your desk, that's what you will notice most in the otherwise unchanged room.

25 Nov 2020

Researchers describe a simple, inexpensive way to measure drug dissolution

When you take a time-release drug, you count on it doing what the package says: release the drug slowly into your bloodstream to provide benefits over the specified period of time.

Multimodal ion-electronic skin can measure tactile sensation and temperature at the same time

What if we didn't have skin? We would have no sense of touch, no detection of coldness or pain, leaving us inept to respond to any situation.

Scientists show SARS-CoV-2's viral replication with 3D integrative imaging

A team of researchers at Heidelberg University in Germany have performed a detailed imaging analysis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection to determine how the virus reprograms infected cells.

24 Nov 2020

Researchers recommend antibody cocktail to tackle SARS-CoV-2 mutations

A new study released on the medRxiv* preprint server indicates that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the current coronavirus disease 2019 (COVID-19) pandemic – is developing multiple mutations that affect neutralization by antibodies.

24 Nov 2020

COVID-19: HLA class I genotypes and mortality

The study, published on the preprint server medRxiv, explores the ability of HLA class I molecules to mediate the outcome in COVID-19 patients.

24 Nov 2020

Thromboembolism in COVID-19 patients associated with higher risk of mortality

While respiratory issues continue to be the most common symptom of a COVID-19 infection, new research indicates the disease could also be associated with hypercoagulability, or increased tendency of the blood to clot.

23 Nov 2020

Mildly symptomatic COVID-19 patients may be contagious for longer than previously thought

Researchers in Brazil have reported two cases of people with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) shedding infectious virus for a significantly longer period than has previously been reported.

23 Nov 2020

Speed of test results and frequency of testing are paramount for effective COVID-19 surveillance

For COVID-19 Surveillance, Test Frequency and Turnaround Time Are Paramount, Modeling Suggests Speed of test results and frequency of testing are paramount for effective COVID-19 surveillance, suggests a new study that modeled trade-offs in test sensitivity, test frequency, and sample-to-answer reporting time, in select scenarios.

23 Nov 2020

Study recommends key factors to address U.S. health care costs

Structuring negotiations between insurers and providers, standardizing fee-for-service payments and negotiating prices can lower the United States' health care spending by slowing the rate at which healthcare prices increase, according to a Rutgers study.

Researchers investigate SARS-CoV-2 transmission chain dynamics in the Nordic countries

To date, the coronavirus disease (COVID-19) pandemic has affected over 58.52 million individuals and led to more than 1.38 million deaths worldwide. Second waves of the pandemic are still ongoing in many countries with a massive impact on health care systems and economies.

22 Nov 2020

Inexpensive, rapid-turnaround COVID-19 tests could eliminate the virus within weeks

Testing half the population weekly with inexpensive, rapid-turnaround COVID-19 tests would drive the virus toward elimination within weeks-- even if those tests are significantly less sensitive than gold-standard clinical tests, according to a new study published today by University of Colorado Boulder and Harvard University researchers.

SARS-CoV-2 transmission model predicts when schools can be safely reopened

Can schools safely remain open or reopen during periods of significant community spread of COVID-19? According to predictions from a model of SARS-CoV-2 transmission in the school setting, yes - if appropriate precautions are followed both in school and in the community.

20 Nov 2020

Universal screening for SARS-CoV-2 may be an ineffective mitigation strategy, says study

A team of researchers in the Netherlands have reported that regular, universal and random screening and isolation of infectious individuals may not be a viable strategy for reopening society after bringing a wave of SARS-CoV-2 under control.
