OBJECTIVES: To assess the impact of high body mass index (BMI) on patient-reported outcomes in sarcoidosis patients and healthy persons. METHODS: In this case-control study, we investigated symptoms of fatigue and dyspnoea, health status, BMI and spirometric tests in 184 sarcoidosis patients and the same number of sex- and age-matched healthy subjects. Fatigue was assessed using the fatigue scale (FS), dyspnoea was determined by the baseline dyspnoea index (BDI) and health status was measured using the respiratory-specific St George's Respiratory Questionnaire (SGRQ). RESULTS: There were significantly more subjects with increased BMI (>25 kg /m2) among the sarcoidosis patients than among the healthy volunteers (>237.675, P < 0.01). Sarcoidosis patients also had a greater probability of having a higher BMI (P < 0.01, OR 1.18, 95%CI 1.07-1.3). We found significantly lower BDI scores and forced expiratory volume in 1 s/ forced vital capacity, as well as higher total SGRQ and total FS scores in sarcoidosis patients than in healthy individuals (P < 0.01 for all differences). CONCLUSION: Sarcoidosis significantly reduces patients' health status, both independently and also due to increased BMI. Reduction in BMI may contribute to improved spirometry results and health status of patients with sarcoidosis. © 2013 The Union.

SETTING: The Institute for Pulmonary Diseases of Serbia, which specialises in diagnosis and treatment of lung diseases in a region with approximately 550-600 TB admissions per year. OBJECTIVE: To assess the occupational risk of tuberculosis (TB) among health care workers (HCWs) employed at this institution. DESIGN: Retrospective analysis of morbidity of TB among HCWs over a 12-year period (1986-1997). The incidence of TB among HCWs was estimated by the frequency of bacteriologically or histologically confirmed active disease. All HCWs at our institution underwent routine pre-employment screening, consisting of verification of BCG vaccination, PPD tuberculin reactivity, chest X-ray and laboratory evaluation. RESULTS: Of an average 267 employed HCWs, pulmonary TB occurred in nine (six nurses and three laboratory technicians). Cumulative incidence for HCWs was 3451/100000, compared to 454/100000 in the general population, for an incidence rate ratio of 7.6. CONCLUSION: The risk of TB among HCWs employed at the Institute for Pulmonary Diseases of Serbia in Belgrade is 7.6 times higher than that observed in the general population, suggesting occupational acquisition of TB.

OBJECTIVE: Recent studies demonstrated that current European Respiratory Society/American Thoracic Society spirometric reference equations, used in general population, may not be applicable in population of elite athletes. Althought it is well known that physical activity may affect lung volumes, the effect of sporting activity on pulmonary function testing indices was never examined. The aim of this study was to examine the differences in functional respiratory parameters in various types of sports by measuring lung volumes and to extend the existing factors as well as sport disciplines which affect respiratory function the most. SUBJECTS AND METHODS: A total of 1639 elite male athletes, aged 18-35 years were divided in 4 groups according to the predominant characteristics of training: skill, power, mixed and endurance athletes. They performed basic anthropometric measurements and spirometry. Groups were compared, and Pearson's simple correlation was performed to test the relation between anthropometric and spirometric characteristics of athletes. RESULTS: All anthropometric characteristics significantly differed among groups and correlate with respiratory parameters. The highest correlation was found for body height and weight. CONCLUSIONS: Sports participation is associated with respiratory adaptation, and the extent of adaptation depends on type of activity. Endurance sports athletes have higher lung volumes in comparison with skill, mixed and power group of sport.

Introduction: Unlike large population studies about cardiovascular components and how they adapt to intensive physical activity, there is less research into the causes of enlargement of the respiratory system in athletes (e.g. vital capacity, maximum flow rates and pulmonary diffusion capacity). The purpose of this research was to study and compare pulmonary function in different types of sports and compare them with controls in order to find out which sports improve lung function the most. Materials and method: Pulmonary functional capacities, vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and maximum voluntary ventilation (MVV) of 493 top athletes belonging to 15 different sports disciplines and of 16 sedentary individuals were studied. Pulmonary function test was performed according to ATS/ERS guidelines. Results: Basketball, water polo players and rowers had statistically higher vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1) than the healthy sedentary control individuals. Football and volleyball players had lower VC while FVC was higher in the football group compared to controls. Peak expiratory flow was lower in boxing, kayak, rugby, handball, taekwondo and tennis. The maximum voluntary ventilation (MVV) was significantly higher in water polo players and rowers. Boxers had statistically lower MVV than the controls. Players of other sports did not differ from the control group. Conclusion: The study suggests that specific type of training used in basketball, water polo or rowing could have potential for improving pulmonary function and rehabilitation. © 2014 Sociedade Portuguesa de Pneumologia.

Background: Physical activity has a positive effect on the function of the whole human body system. The influence of physical activity on the development of the respiratory system is still a matter for debate. Swimming is considered the sport with the most profound effect on the lungs. Aim: The first aim was to determine pulmonary function and to correlate it with anthropometric features of sportsmen, represented by land- and the water-based elite athletes comparing with their sedentary counterparts; the second aim was to examine whether the training factors (frequency and amount) influence pulmonary function in swimmers, when controlled for anthropometric features. Methods: Thirty-eight elite male swimmers were matched for age and sex with two hundred and seventy-one elite football players and one hundred controls who were not involved in any routine exercise. Lung volumes were recorded by Pulmonary Function test and analyzed statistically. Results and conclusion: Swimmers had statistically higher values of VC, FVC, FEV1 and FEV1/FVC when compared to both the football players and the controls, as the latter two showed no in-between differences. There was significant positive correlation between age, body weight and body height and each of the above named pulmonary parameters, when presented separately for swimmers, football players and the control group. When controlled for the anthropometric features, larger lung volumes in swimmers were not influenced by training period, age at the beginning of training and weekly extent of personal training. Further comprehensive longitudinal studies are needed to confirm these observations. © 2015 Sociedade Portuguesa de Pneumologia.
