Dimensions of sleepiness and their correlations with sleep-disordered breathing in mild sleep apnea.
There are many ways of assessing sleepiness, which has many dimensions. In patients presenting a borderline apnea-hypopnea index (AHI, expressed as events/hour of sleep), the mechanisms of excessive daytime sleepiness (EDS) remain only partially understood. In the initial stages of sleep-disordered breathing, the AHI might be related to as-yet-unexplored EDS dimensions. ⋯ Our results underscore the multidimensionality of EDS in mild sleep apnea.

Randomized Controlled Trial
Physical therapy in the immediate postoperative period after abdominal surgery.
A series of pulmonary complications can occur after abdominal surgery. Therefore, it is necessary to introduce appropriate treatment early in order to minimize postoperative complications. ⋯ This was a randomized clinical trial, in which one group of patients was submitted to physical therapy in the postoperative recovery room and, subsequently, in the infirmary, whereas another group was submitted to physical therapy in the infirmary exclusively. We conclude that physical therapy performed in the immediate postoperative period minimizes losses in lung function and respiratory muscle strength, as well as shortening recovery room stays.

To determine the prevalence of and factors associated with smoking among medical students, as well as to evaluate the profile of this group. ⋯ The prevalence of smoking remains significant among medical students. Therefore, it is fundamental that we develop more effective strategies for smoking prevention and cessation in order to reduce the number of smokers among future doctors.

To identify associations between genetic polymorphisms (in the MBL2, TGF-beta1 and CD14 genes) and the severity of the lung disease in patients with cystic fibrosis (CF), as well as between the presence of DeltaF508 alleles and lung disease severity in such patients. ⋯ There was an association between the TC genotype of the T869C polymorphism (TGF-beta1) and mild pulmonary disease in CF patients. In the CD14 gene, the TT genotype seems to be a risk factor for pulmonary disease but is not a modulator of severity. We found no association between being a DeltaF508 homozygote and presenting severe lung disease.
