Influence of #sleep problems and co-occurring musculoskeletal pain on long-term prognosis of chronic low #backpain: the HUNT Study

Compared with persons without sleeplessness, persons who often/always experienced sleeplessness had a lower probability of recovery from chronic LBP (RR 0.65, 95% CI 0.57 to 0.74 in women and RR 0.81, 95% CI 0.69 to 0.95 in men). Although there was no clear evidence of statistical interaction between sleeplessness and co-occurring musculoskeletal pain, women and men who often/always experienced sleeplessness and had ≥5 additional chronic pain sites … Continue reading Influence of #sleep problems and co-occurring musculoskeletal pain on long-term prognosis of chronic low #backpain: the HUNT Study

Association of Long-term Ambient #Ozone Exposure With Respiratory Morbidity in #Smokers

..In adjusted analysis, a 5-ppb (parts per billion) increase in ozone concentration was associated with a greater percentage of emphysema (β = 0.94; 95% CI, 0.25-1.64; P = .007) and percentage of air trapping (β = 1.60; 95% CI, 0.16-3.04; P = .03); worse scores for the mMRC Dyspnea Scale (β = 0.10; 95% CI, 0.03-0.17; P = .008), CAT (β = 0.65; 95% CI, 0.05-1.26; P = .04), and SGRQ (β = 1.47; 95% CI, 0.01-2.93; P = .048); lower FEV1% predicted value (β = −2.50; … Continue reading Association of Long-term Ambient #Ozone Exposure With Respiratory Morbidity in #Smokers
