Nasal and systemic inflammatory profile after short term smoking cessation.
Smoking cessation promotes health benefits and, despite cigarette smoking be an important pro inflammatory stimulus, there are few studies concerning the nasal and systemic inflammation; as well as the mucociliary clearance behavior in smokers after short period of smoking cessation. ⋯ The short term smoking abstinence decreased systemic inflammation and improved nasal mucociliary clearance, despite not having changed the nasal inflammation.

Effect of CPAP treatment on plasma high sensitivity troponin levels in patients with obstructive sleep apnea.
Obstructive sleep apnea (OSA) is associated with an increased prevalence of cardiovascular diseases. New generations of highly sensitive assays for cardiac troponin (hs-cTnT) have been introduced recently, and a number of clinical observations have challenged the notion that troponins are only increased in blood following irreversible necrosis. ⋯ This study shows that the percentage of subjects with detectable hs-cTnT is associated with the presence of OSA. It also evidences that treatment with CPAP is followed by a rise in hs-cTnT concentrations. It is reasonable to suggest that CPAP therapy might induce a potential degree of cardiac stress, resulting in deleterious consequences for the heart.
