“Objective. We have designed
the present study to compare prevalent lifetime cases of diagnosed asthma or exercise-induced asthma, as well as current related respiratory symptoms, across two different levels of former athletes and non-athletes. Methods. Demographic, behavioral, and AZD6738 purchase asthma history information, as well as current related respiratory symptoms, were obtained through a questionnaire from 627 subjects (290 former elite and 201 non-elite athletes that competed between 1969 and 2005, and 136 control subjects that had never been athletes). Results. Non-athletes presented a higher percentage of subjects reporting the existence of symptoms associated with exercise or vigorous activities. Former athletes who reported having practiced mostly in indoor facilities presented significant lower risk for asthma than outdoor athletes (Odds Ratio = 0.48, 95% CI = 0.25-0.94). Multiple regression analysis (where “”B”" refers to unstandardized coefficients) showed that former elite (B = -0.85, p < .001) and non-elite athletes (B =
Lapatinib molecular weight -0.70, p < .001) were less prone to be affected by asthma-related symptoms than non-athletes. Athletes with careers that lasted more than 20 years were more likely to possess asthma-related symptoms than the ones with shorter careers (3-7 years, B = -0.47, p < .001; 8-14 years, B = -0.42, p < .01; 15-20, B = -0.32, p < .05). Conclusions. Non-athletes seem to have a higher prevalence of respiratory symptoms. Among former athletes, career characteristics seem to play a crucial role, with special emphasis to its duration, where the most lengthy seem to be more associated with respiratory symptoms.”
“Objectives: In the first place, to evaluate skeletal changes of the maxilla and mandible induced by surgical-orthodontic correction of malocclusions class III with long-face syndrome and secondly, to analyze the stability of these skeletal changes in the long term (more than 6 years).
Design of Study: A retrospective, unicentric and longitudinal study of 19 patients
who had undergone surgical and orthodontic therapy for selleck compound class III skeletal malocclusion with long-face syndrome was undertaken. A cephalometric analysis based on 8 angle measurements, and statistical analyses at three different points in time (before orthodontic treatment, after orthognathic surgery and after a retention period of at least 6 years) were carried out.
Results: The changes produced following surgery show that, with the exception of the maxillary plane and the facial axis, all other variables presented changes of great statistical difference.
Conclusions: Skeletal changes after orthodontic-surgical correction present maxillary advance, mandibular regression and mandibular anterorotation.
