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).
Soluble TNF receptor II increased in MS patients
As reported in the Journal of Neuroimmunology, soluble tumor necrosis factor receptor II levels are increased in patients with untreated multiple sclerosis (n-161) compared to healthy controls (n=46), and the levels increased over a 2-year follow-up, but were not associated with the severity of disability.
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.
