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.
