It is well established that the SARS-CoV-2 virus responsible for the COVID-19 disease is transmitted via respiratory droplets that infected people eject when they cough, sneeze or talk. Consequently, much research targets better understanding droplet motion and evaporation to understand transmission more deeply. In a paper in Physics of Fluids, researchers developed a mathematical model, proceeding from...
While the use of face masks in public has been widely recommended by public health officials during the current COVID-19 pandemic, there are relatively few specific guidelines pertaining to mask materials and designs. A study from Florida Atlantic University, in the Physics of Fluids, looks to better understand which types are best for controlling respiratory droplets...
East Germany has many more hospitalisations for heart failure compared to West Germany despite a nationwide healthcare system, according to research presented today on HFA Discoveries, a scientific platform of the European Society of Cardiology (ESC). Heart failure is the most common reason for hospital admissions and is responsible for a large part of the total...
Lifetime discrimination is a chronic stressor that may increase the risk for hypertension also known as high blood pressure, in African Americans, according to new research published today in Hypertension, an American Heart Association journal. “Previous studies have shown that discrimination affects African Americans’ health; however, this research is one of the first large, community-based studies...
In April, Gov. Gavin Newsom launched a multimillion-dollar state initiative to bring COVID-19 testing to the people and places with the least access: rural towns and disadvantaged inner-city neighborhoods. California is now halting its expansion, citing costs, even as the state is getting walloped by record-setting spikes in new infections and double-digit increases in hospitalizations....
Office visits for ongoing prescribing of skeletal muscle relaxant drugs tripled from 2005 to 2016, according to a new study from researchers in the Perelman School of Medicine at the University of Pennsylvania. Moreover, in 2016, nearly 70 percent of patients prescribed muscle relaxants were simultaneously prescribed an opioid — a combination that has the...
The study, published recently in Circulation Research and led by a team from King’s College London, has investigated how nitrogen dioxide can impact the cardiovascular system. The study examined the blood chemistry and cardiovascular changes of 12 healthy volunteers. They sat next to a domestic gas cooker for ninety minutes followed by ninety minutes with normal background...
The majority of children with COVID-19 in 26 countries fared well clinically compared to adults during the first four months of the pandemic, a newly released study shows. Researchers from the Long School of Medicine at The University of Texas Health Science Center at San Antonio prepared the study, which is the largest systematic review...
Analysis from the University of Surrey suggests that the economies of countries such as America, the United Kingdom and Germany should prepare for a long slow recovery with prolonged periods of instability. Rates of growth across member states of Organisation for Economic Co-operation and Development (OECD) have been in decline since the 1970s, a phenomenon...
Kindergartners in face masks. Closed playground structures. Random COVID-19 testing. They are among the long list of hypothetical scenarios for school in the pandemic era. And as lawmakers and educators reimagine the K-12 model for fall, a new survey assessed parents’ plans for in-person school and support for 15 potential measures to reduce the risk...
