Researchers found that women are less likely to receive early treatment following a heart attack, including aspirin and thrombolytic therapy. Despite this, there is no apparent effect on 30-day mortality rates when accounting for severity of illness and other factors.
Scientists at Max-Planck-Gesellschaft developed a simple electrochemical procedure to fabricate three-dimensional microstructures. The innovation lies in applying ultrashort voltage pulses between the electrodes, which confines the electrochemical reaction to a small region and enables precise micromachining.
A study published in the Journal of the American Medical Association found that nearly 90% of high-risk patients received antibiotic instructions, while only 60% of moderate-risk patients did. The study also revealed that 25% of low-risk patients incorrectly received antibiotics and 13% chose not to take them.
A randomized controlled trial found that a new anti-inflammatory drug decreased kidney function at the same rate as an older medication. Prompt treatment with three powerful antiretroviral drugs after HIV exposure prevented infection in a young girl, according to researchers.
A broad analysis by UC San Francisco researchers found that oral contraceptives generally double the risk of stroke, especially with high estrogen doses. The added risk is miniscule and remains low even when doubled, but caution is advised for smokers and those with high blood pressure.
A study found that a specialized nurse intervention significantly reduced asthma hospitalizations and missed work days, while also lowering healthcare costs. The program provided social support and education to patients, resulting in improved quality of life and substantial cost savings.
A recent study found that a biological clock gene in honeybees is more active in older bees, especially foragers who perform jobs outside the hive. The discovery suggests molecular connections between the division of labor and biological clocks in social insects.
Researchers found that certain genes in blood vessels produce a protective protein called HO-1, which inhibits atherosclerosis. This discovery provides new leads for treating and preventing heart disease by targeting these genetic pathways.
Researchers at the University of Illinois have developed visual inspection procedures to assess corrosion damage in deck beams, evaluate the remaining service life of bridges, and identify potential safety risks.
