The heart effects of antidepressants may depend as much on the patient as the drug

Antidepressants differed in their effects on QTc, with amitriptyline and escitalopram producing small average increases, and the magnitude of changes varying according to individual patient characteristics. The trials did not detect an increase in early major cardiovascular events or non-suicidal sudden death, but they were not large or long enough to rule out rare or later cardiovascular events.

Beetroot juice may make swimming feel easier without making swimmers faster

A systematic review and meta-analysis of 12 studies, with nine contributing data from 120 swimmers, found no significant improvement in swimming time-trial performance or post-exercise blood lactate with beetroot juice or dietary nitrate supplementation. Supplementation produced a small reduction in perceived exertion, but the effect varied across studies, and the certainty of evidence for swimming performance was low.

Happy at work, better at the job? A study of young employees offers clues

Researchers studying 412 employees aged 35 or younger in Spain found that higher job satisfaction was associated with better task and contextual performance. Work that negatively affected mental health and personal life was associated with poorer contextual performance and more counterproductive behavior, while supervisor emotional accessibility and organizational respect showed no significant direct links to performance.

Rising prescription and supplement use poses health risks for seniors

Older Americans are increasingly taking multiple prescription medications and dietary supplements. Although the prevalence of potentially major drug-drug interactions has declined slightly, more than 1 in 5 older adults are potentially at risk, according to a USC-led study published September 24 in JAMA.
