Researchers Challenge New Guidelines on Aspirin in Primary Prevention

New guidelines recommend aspirin use in primary prevention for people ages 40 to 70 years old who are at higher risk of a first cardiovascular event, but not for those over 70. Yet, people over 70 are at higher risks of cardiovascular events than those under 70. As a result, health care providers are understandably confused about whether or not to prescribe aspirin for primary prevention of heart attacks or strokes, and if so, to whom.

Combination Drug Therapy For Childhood Brain Tumors Shows Promise In Laboratory Models

In experiments with human cells and mice, researchers at the Johns Hopkins Kimmel Cancer Center report evidence that combining the experimental cancer medication TAK228 (also called sapanisertib) with an existing anti-cancer drug called trametinib may be more effective than either drug alone in decreasing the growth of pediatric low-grade gliomas. These cancers are the most common childhood brain cancer, accounting for up to one-third of all cases. Low grade pediatric gliomas arise in brain cells (glia) that support and nourish neurons, and current standard chemotherapies with decades-old drugs, while generally effective in lengthening life, often carry side effects or are not tolerated. Approximately 50% of children treated with traditional therapy have their tumors regrow, underscoring the need for better, targeted treatments.

Recommended diuretic causes more side effects than similar hypertension drug

Chlorthalidone, the guideline-recommended diuretic for lowering blood pressure, causes more serious side effects than hydrochlorothiazide, a similarly effective diuretic, according to a new study led by researchers at Columbia University Irving Medical Center. The findings, published in JAMA Internal Medicine…

Zooming in on breast cancer reveals how mutations shape the tumour landscape

Scientists have created one of the most detailed maps of breast cancer ever achieved, revealing how genetic changes shape the physical tumour landscape, according to research funded by Cancer Research UK and published in Nature Cancer today (Monday). An international…

Organic-cation intercalation: An effective strategy for manipulating band topology and superconductivity

In the recent article published in Science Bulletin , the researchers develop an effective organic-cation intercalation strategy to manipulate the interlayer coupling of layered materials, and obtain a class of organic-inorganic hybrid crystals with tailored topological properties and enhanced superconductivities.…

Visualizing diffusive dynamics beyond tracking limit with standard optical microscope

Evaluating the spatio-temporal distribution of diffusion coefficients for high-concentration Brownian particles without fluorescent labeling nor tracking them from microscopy movie data analysis based on the statistical physics

Antioxidant in mushrooms may relieve features of ‘pregnancy hypertension’

Pregnancy hypertension, or Pre-eclampsia, is a complex disorder of pregnancy. Treatment of elevated blood pressure can manage the condition in the mother, but in severe cases delivery is needed, which can present a major problem to the baby if it…
