Estrogen possible risk factor in disturbed heart rhythm

Researchers from Linköping University found that estrogen impairs the function of a specific ion channel, Kv7.1/KCNE1, which is associated with long QT syndrome and arrhythmia. This suggests that estrogen may be a risk factor for certain types of heart rhythm disturbances in women with hereditary mutations.

PCR panels reduce costs, hospitalizations and antibiotic use for acute GI infections

A new study published in Journal of Clinical Microbiology shows that using multiple PCR panels can identify more pathogens, notably diarrhea-causing E. coli and enteric viruses, and do so more rapidly than a conventional workup. This results in lower healthcare costs, reduced hospitalizations, and decreased antibiotic use.
