Sleep duration linked to lung cancer risk
As reported in BMC Public Health, men (age range, 42-60 years) who slept < 7 h/night or > 8 h/night are at increased risk for lung cancer. Specifically, amongst current smokers, the HR for lung cancer in men who slept < 6.5 h/night or > 8 h/night was 2.23 and 2.09, respectively. It is thought that melatonin excretion and/or low-grade inflammation account for this observation.
Muscle strength in adolescence decreases CVD risk
As reported in BMC Medicine, adolescents (n=38588) with the highest tertile of muscle strength had a decreased risk of CVD (HR=0.88) compared to adolescents with the lowest tertile of muscle strength after 42 y of follow-up. Of note, low muscle strength in adolescence by itself had no effect on CVD risk in middle age (HR=0.99). In contrast, high muscle strength in adolescence significantly decreased the risk of CVD in middle age (HR=1.31).
Mean platelet volume predicts silent cerebral infarction
As reported in the Internal Medicine Journal, the mean platelet volume is increased in patients with a silent cerebral infarction than in those without (10.4 vs. 9.2 fL). The OR for silent cerebral infarction was 7.822 in patients in the highest mean platelet volume quartile compared to the lowest quartile.
