Light physical activity such as gardening, strolling through a park, and folding clothes might be enough to significantly lower the risk of cardiovascular disease among women 63 and older, a new study has found. This kind of activity, researchers said, appears to reduce the risk of cardiovascular disease events such as stroke or heart failure by up to 22 percent, and the risk of heart attack or coronary death, by as much as 42 percent.

A sound, a smell, a word can all flood our minds with memories of past experiences. In a study of epilepsy patients, researchers at the National Institutes of Health found that split seconds before we recall these events tiny electrical waves, called ripples, may flow through key parts of our brains that help store our memories, setting the stage for successful retrieval.

Researchers say a widely-used antifungal drug may hold promise for treating people with cystic fibrosis, a life-threatening genetic disorder that causes serious damage to the lungs. In studies using human cells and animals models, the researchers found that the medication, called amphotericin, helps lung cells function in a way that could make it easier for patients to fight chronic bacterial lung infections that are a hallmark of the disease.

Researchers have identified changes in brain connectivity and brain activity during rest and reward anticipation in children with anhedonia, a condition where people lose interest and pleasure in activities they used to enjoy. The study, by scientists at the National Institute of Mental Health (NIMH), part of the National Institutes of Health, sheds light on brain function associated with anhedonia and helps differentiate anhedonia from other related aspects of psychopathology.

An analysis of a previous study has found more evidence to support giving the steroid betamethasone to pregnant women at risk of late-preterm delivery (between 34 and 36 weeks of gestation), according to a network funded by the National Institutes of Health. Hospital stays for infants whose mothers received the drug cost less on average, compared to stays for infants whose mothers did not take the drug. The study appears in JAMA Pediatrics.

A new study finds vitamin D may be protective among asthmatic obese children living in urban environments with high indoor air pollution. The study out of John Hopkins University School of Medicine, funded by the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health, was published in The Journal of Allergy and Clinical Immunology: In Practice.

Eighty-six percent of individuals who entered HIV care soon after diagnosis maintained viral suppression after 48 weeks during a clinical trial conducted at four National Institutes of Health-funded Centers for AIDS Research (CFARs) across the United States. Participants in the clinical trial, called iENGAGE, achieved viral suppression in an average of just 63 days. The findings were presented in a poster at the Conference on Retroviruses and Opportunistic Infections(link is external) (CROI 2019) in Seattle.

Among people with HIV in Latin America, those diagnosed with tuberculosis (TB) at an initial clinic visit were about twice as likely to die within 10 years as people not initially diagnosed with TB, according to findings from a large observational study.

HIV prevention study finds universal “test and treat” approach can reduce new infections

New HIV infections declined by 30 percent in southern African communities where health workers conducted house-to-house voluntary HIV testing, referred people who tested positive to begin HIV treatment according to local guidelines, and offered other proven HIV prevention measures to those who tested negative. Local guidelines evolved during the study from offering HIV treatment based on immune health to offering immediate treatment for all.
