Researchers from Children’s Hospital of Philadelphia (CHOP) affiliated with the CHOP Epilepsy Neurogenetics Initiative (ENGIN) have compiled a complete genetic and clinical analysis of more than 400 individuals with SCN2A-related disorder, which has been linked to a variety of neurodevelopmental disorders, including epilepsy and autism. By linking clinical features to genetic abnormalities in a standardized […]

Heart-healthy lifestyles linked to lower risk of future cancers
In addition to lowering risk of heart disease, maintaining a heart-healthy lifestyle may pay off in lower risk for developing cancer, researchers from Massachusetts General Hospital (MGH) and other centers in the United States and the Netherlands have found. Looking at the potential link between cardiovascular disease (CVD) and cancer among participants in two large […]
Research shows how mutations in SARS-CoV-2 allow the virus to dodge immune defenses
The vast majority of people infected with SARS-CoV-2 clear the virus, but those with compromised immunity—such as individuals receiving immune-suppressive drugs for autoimmune diseases—can become chronically infected. As a result, their weakened immune defenses continue to attack the virus without being able to eradicate it fully. This physiological tug-of-war between human host and pathogen offers […]
WHO experts to meet on AstraZeneca shot as virus cases surge
WHO safety experts prepared to meet Tuesday over the AstraZeneca coronavirus vaccine whose rollout has been halted in several European countries over blood clot fears, imperilling the pandemic fight as infection rates surge. The three largest EU nations—Germany, Italy and France—joined others in suspending the shot Monday, dealing a blow to the global immunisation campaign […]
Ultrasound reveals the human brain vasculature down to the microscopic scale
Mapping the cerebral vascular network in human patients, at unprecedented scales: This tour de force has been achieved by the French laboratory Physics for Medicine Paris (ESPCI Paris-PSL, Inserm, CNRS). In a study published on the front page of Nature Biomedical Engineering, the research team details its method—ultrasound localization microscopy, which combines ultrafast sonography and […]
Experts say getting back to a mask-free norm may take time for some
As more people across the country become vaccinated against COVID-19, the CDC released guidelines last Monday allowing for fully vaccinated people to gather together without masks. But pulling off the mask and adjusting to life before the pandemic will come with a learning curve, according to experts. Dr. Aderonke Pederson, an instructor of psychiatry and […]
Common household chemicals tied to preemie births
Even when women do their best to have a safe pregnancy, chemicals commonly found in the home could still raise their risk for premature delivery, a new study shows. The chemicals—called polybrominated diphenyl ethers (PBDEs)—are used as flame retardants in items like furniture and carpets. For the study, researchers analyzed blood samples from over 3,500 […]
Survivors struggle as scientists race to solve COVID mystery
There was no reason to celebrate on Rachel Van Lear’s anniversary. The same day a global pandemic was declared, she developed symptoms of COVID-19. A year later, she’s still waiting for them to disappear. And for experts to come up with some answers. The Texas woman is one of thousands of self-described long-haulers, patients with […]
Poor survival after heart attack linked to excess levels of signaling protein in heart
About 6.2 million Americans suffer from heart failure, an incurable disease with a staggering mortality rate—some 40 percent of patients die within five years of diagnosis. Heart failure is one form of heart disease for which new therapies are desperately needed. Now, in new work, scientists at the Lewis Katz School of Medicine (LKSOM) at […]
