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.
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.
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.
