Pulmonary function studies in obese individuals have alerted the pathophysiological changes due to weight gain. However, these changes are not fully explained yet. Objective: To evaluate and analyze the pulmonary function of obese adults in the city of Manaus (AM, Brazil) and to correlate the parameters of spirometry with weight and BMI. Method: A descriptive cross-sectional study, in which pulmonary function of 22 adults with grade III obesity was evaluated pre and post bronchodilator administration, performed at the Adriano Jorge Hospital Foundation—FHAJ. Results: Of the 22 patients evaluated, 6 were male and 16 were female; mean age was 37.1 ± 7.4 years, with a weight of 134.2 ± 28.6 kg and a BMI of 51.1 ± 9.4 kg/m2, corresponding to grade III obesity. Spirometry showed a reduction in values obtained from Forced Vital Capacity (FVC), Forced Expiratory Volume in the first second (FEV1) and Peak Expiratory Flow (PEF) in relation to those predicted, with 23% of restrictive disorders. There were negative correlations between BMI and PEF, weight and FVC, weight and PEF. The P value for correlation of weight and FEV1 is not statistically significant. Conclusion: Restrictive and obstructive disorders are prevalent in the population with grade III obesity. Correlations between pulmonary function and BMI/weight were negative for this specific population.

Introduction: Obesity has been considered a global epidemic and a serious public health problem closely related to other diseases. Moreover, obese individuals have limitations in physical capacity and pulmonary function. Weight loss induced by bariatric surgery appears to help reverse this situation. However, questions about physical capacity and lung function, and its relationship with body composition remain to be clarified. Objective: To evaluate the physical capacity, body composition and lung function in women undergoing bariatric surgery. Methods: Twenty five women who underwent bariatric surgery between 6 and 24 months ago, and 10 non-obese women were evaluated for exercise capacity by the six minutes walk test (6 MWT), body composition by bio-electrical impedance analysis and lung function by spirometry and measurement of maximal static respiratory pressures. Results: Subjects with BMI <30 kg/m2 were found to have better physical performance, demonstrated by increased 6 MWT distance, not differing from non-obese women. When compared with non-obese women, there were no significant differences in body composition and lung function. Higher BMI was correlated with shorter distances in 6 MWT. Conclusion: 6 to 24 months after surgery, when the weight loss of patients who underwent bariatric surgery reaches levels considered non-obese, it provides improvement in physical performance to a level similar to that of non-obese patients.

Open Journal of Thoracic Surgery (OJTS) , 2013, DOI: 10.4236/ojts.2013.32008

Objective: To assess preoperative and postoperative spirometry values in patients undergoing lobectomy for sequelae of pulmonary tuberculosis. Method: A total of 20 patients (10 males) with history of treatment for tuberculosis and presenting with symptomatic sequelae (repeat infection or hemoptysis) who sought assistance at the chest surgery outpatient clinic between 11.09.07 and 04.02.10, were selected for the study. Only patients that met theeligibility criteria (symptomatic, submitted to tuberculosis treatment) were included in the study. The age of patients ranged from 15 to 56 years (mean: 35.75 years). The average treatment time for tuberculosis was 6 months and onset of symptoms occurred between 01 and 32 years after treatment. To assess the impact of surgery on the variables VC, FVC, FEV1, FEV1/FVC, FEF and PEF preoperative values were compared with postoperative values at 1st, 3rd, 6th and 12th month using the paired t test. The level of significance (α) applied for all tests was 5% where a value of p < 0.05 was considered significant. Results: 11 patients were treated because of recurrent infections and 9 because of haemoptysis. The most common lobectomy was right upper lobectomy (7 patients), followed by left upper lobectomy (6 patients), left lower lobectomy (6 patients), and right middle lobectomy (1 patient). There were no postoperative complications. There was no postoperative mortality. Conclusion: Based on the results of the present study, it can be concluded that, at the 12th postoperative month, spirometric parameters of patients with tuberculosis sequelae submitted to lobectomy had returned to preoperative levels.

Pharmacology & Pharmacy (PP) , 2013, DOI: 10.4236/pp.2013.42019
Abstract: Bronchial asthma may result in oxidant/antioxidant imbalance. Antioxidant vitamins E and C concentrations were estimated in plasma of asthmatics that were also simultaneously subjected to spirometry and matched with healthy controls showing significant changes in both the vitamin concentrations. Vitamin C showed strong correlation whereas vitamin E was not correlated with spirometry.

Open Journal of Respiratory Diseases (OJRD) , 2013, DOI: 10.4236/ojrd.2013.34025
Abstract: Background: Spirometric reference values vary substantially across ethnic groups, and remain largely poorly characterized among Africans. We derived spirometric reference equations for adult Cameroonians and compared their performance with those derived from other ethnic groups. Methods: Spirometric variables according to the American Thoracic Society/European Respiratory Society 2005 guidelines were acquired in voluntary healthy non-smoker subjects in Yaounde (Capital City) and Foumbot (semi-urban area in West Region), in Cameroon during November 2011 to January 2012 (Yaounde) and August 2012 (Foumbot). Reference equations were derived separately for men and women from multiple linear regressions. Results: A total of 411 subjects (206 men) met the inclusion criteria. The mean age was 39.5 ± 16.1 years (min - max: 18 - 85 years) for men and 39.2 ± 14.1 years (18 - 90 years) for women. Age and height were the only variables significantly associated with spirometric values in the final linear regression models. Derived reference values were lower than those derived from Global Lung Initiative 2012 equations for different ethnic groups, except for the forced expiratory volume in 1 second/forced vital capacity ratio (FEV1/FVC ratio). The mean FEV1/FVC ratio was 0.88 ± 0.07 for Cameroonian men and 0.89 ± 0.07 for Cameroonian women. Variations in the performance of derived models in bootstrap internal validation were marginal. Conclusion: This study highlights the importance of deriving specific predictive equations for each ethnic group. The use of adjustment factors applied to Caucasian equations when compared with the values derived in our study leads to an overestimation of the values for FEV1 and FVC.

Abstract: A cross sectional study conducted among volunteers healthy non-smoking adults Subjects. We divided the subjects into two groups according to their BMI. The first group consisted of non-obese subjects with BMI of 18 to 24.9 kg/m2 and the second group consisted of obese subjects with BMI of 30 kg/m2 and above. Subjects underwent spirometry tests according to American thoracic society standards with measurement of the following values: the forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow rate (PEF) and forced mid-expiratory flow (FEF25-75).The total subjects were 294 with a mean age of 32 years. There were 178 males and 116 females subjects. We found no significant differences in FEV1 (p value = 0.686), FVC (p value = 0.733), FEV1/FVC Ratio (p value = 0.197) and FEF25-75 (p value = 0.693) between the obese and non-obese subjects. However, there was significantly difference in PEF between the two groups (p value < 0.020).Obesity does not have effect on the spirometry tests (except PEF) among health non-smoking adults. We recommend searching for alternative diagnosis in case of findings abnormal spirometry tests results among obese subjects.Obesity is a chronic medical condition characterized by an excessive accumulation of fat on human body that causes a generalized increase in body mass. It is measured by using body mass index (BMI) which is a reflection of weight and height. Body mass index (BMI) is calculated as the weight in kilograms divided by the square of the height in meters (BMI = weight (kg)/height (m2)). The world Health Organization (WHO) classified obesity using BMI cut-off values of 25 and 30 kg/m2. Body mass index (BMI) of 18 to 24.9 kg/m2 is considered normal weight, a BMI of 25.0-29.9 kg/m2 is considered overweight and a BMI of 30 kg/m2 or higher is considered obesity [1].Obesity has been associated with many health consequences, including but not limited to diabetes, hypertension, hyperlpidemia, ischemic

Abstract: In this cross-sectional study, a questionnaire focusing on respiratory symptoms and smoking habits was administered to all participants who accepted to join the study.All subjects also underwent a physical examination and a pulmonary function test performed with portable spirometer. According to GOLD criteria, subjects who had post-bronchodilator FEV1/FVC < 70% and negative reversibility test were classified as COPD.A total of 685 teachers were included [female n = 307 (45%), male n = 378 (55%)] with mean age 38.9 ± 8.9 years. Smoking habit was evaluated in 660 subjects: 291 (44.1%) were smokers, 252 (38.2%) were non-smokers and 117 (17.7%) were ex-smokers. Pulmonary function test was available in 651 subjects and 510 (78.3%) were defined as normal on spirometric analysis. Small airway obstruction was found in 115 of the cases (17.7%) in whom FEF25-75 level was found to be lower than 70% predicted. FEV1/FVC level was lower than 70% in 16 subjects (2.5%). Five subjects who had positive reversibility test were excluded from the study. The remaining 11 subjects who were considered as COPD consisted of 2 (18%) females and 9 (82%) males. Six of these subjects were aged over 40 years.Spirometry has an important role in early diagnosis of COPD. Spirometric evaluation of cases with risk factors for COPD could be helpful in diagnosing patients before the progressive decline in lung function begins. Further studies are needed to evaluate whether the interventional strategies at this stage such as smoking cessation could prevent the progression of disease.Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease characterized by chronic progressive airflow limitation that is not fully reversible. As a global health problem, COPD is a major cause of morbidity and mortality worldwide. Today, COPD ranks 6th among all causes of death and it is projected to be the 3rd leading cause of death in 2020 [1].COPD prevalence is below 1% in all age groups accordin
