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.
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.
Relationship benefit in women with IHD
As reported in Clinical Infectious Diseases, HIV-infected patients are at increased risk for non-Hodgkin‘s lymphoma (NHL). Of 6036 patients with 21607 person-years of follow-up, there were 37 incident cases of NHL. Compared to patients with ≤ 50 copies/mL, patients with 51-500 and > 500 copies/mL had HRs of 1.66 and 2.39 for NHL, respectively.
