What makes a ‘wave’ of disease? An epidemiologist explains

Panic about a second wave of coronavirus cases is “overblown,” Vice President Mike Pence wrote in June, implying the U.S. has COVID-19 under control. On the other hand, Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, warns that the U.S. is still firmly within a first wave of cases. As media

Genetic tests may differ in their interpretation of certain variants

(HealthDay)—Different genetic test interpretations have been identified for genetic variants, and some of these can impact patient management, according to a research letter published online June 30 in the Annals of Internal Medicine. Jeffrey A. SoRelle, M.D., from the University of Texas Southwestern Medical Center in Dallas, and colleagues examined the prevalence of different interpretations

Cancer survivors overestimate the quality of their diets, finds first study on the topic

There are 15 million cancer survivors in the United States, and prior research has provided strong evidence that lifestyle interventions, such as diet and physical activity, are especially important in the long-term recovery of cancer survivors. Energy imbalance—when energy expenditure does not equal energy intake- and metabolic changes after cancer treatment can directly affect the

Tracking mobility of individuals offers clues to finding COVID

Harvard scientists are leading a global research network that is using data from mobile devices and social media to document people’s movements during the COVID-19 outbreak and translate that information to help government officials set pandemic policy worldwide. The effort, called the COVID-19 Mobility Data Network, involves about 60 academic research labs working with officials

Pandemic becomes a patchwork of small successes and setbacks

Authorities in China appeared to be winning their battle against an outbreak of coronavirus in Beijing on Saturday, but in parts of the Americas the pandemic raged unabated. Brazil surpassed 1 million confirmed infections, second only to the United States. Europe, in contrast, continued to emerge warily from lockdown, with hard-hit Britain considering easing social

New Beijing outbreak raises virus fears for rest of world

China raised its emergency warning to its second-highest level and canceled more than 60% of the flights to Beijing on Wednesday amid a new coronavirus outbreak in the capital. It was a sharp pullback for the nation that declared victory over COVID-19 in March and a message to the rest of the world about how

Risk of preterm births falls under new initiative

The rate of potentially fatal preterm births in Western Australian hospitals can be safely reduced by up to 20% when a coordinated series of interventions is applied to pregnant women, according to researchers at The University of Western Australia. The detailed research findings, published in PLOS ONE, reveal a 7.6% reduction in preterm births across the

Study underlines importance of adequate PPE and training to prevent COVID-19 infection

Despite being at high risk of exposure to COVID-19, frontline healthcare professionals who were appropriately protected did not contract infection or develop protective immunity against the virus, finds a study from China published by The BMJ today. The researchers acknowledge that the healthcare professionals were working away from home, so had limited social interactions after

Study finds our visual world of color is largely incorrect

Color awareness has long been a puzzle for researchers in neuroscience and psychology, who debate over how much color observers really perceive. A study from Dartmouth in collaboration with Amherst College finds that people are aware of surprisingly limited color in their peripheral vision; much of our sense of a colorful visual world is likely
