ABSTRACT Introduction: obstructive Sleep Apnea Syndrome (OSAS) is a serious confition that compromises the quality of life and survival of patients. Its main risk fator in adults is obesity and the gold standard test for diagnosis is polysomnography (PSG), mainly through the apneia-hypopnea index (AHI). Objective: to analyze the sleep pattern of obese patients with indication for bariatric surgery, determining the main polisomnographic parameters compromised by obesity. Methods: This work is a cross-sectional study with analysis of polysomnography perfomed in patients with obesity in the peroperative period of bariatric surgery at a clinic in Vitória da Conquista/BA during 2017. The Epi Info 7 platform was used for analysis of the data. Results: 58 polysomnographic reports were analyzed, with 56,9% morbdly obese and 43,1% non-morbid. The prevalence of OSAS was 70,68% and de AHI ranged from zero to 84,6 with a mean of 19,47±22,89 e/h. morbidly obese, compared to “non-morbid”, had a longer saturation time below 80% and 90% (0,4±0,93 vs. 0,12±0,45 e 4,87±7,38 vs. 1,36±2,87 respectively; p-value=0,02 in both), worse index respiratory disorders ((29,24±25,36 vs. 16,88±16,21; p-value=0,02), higher AHI (24,71±25,68 vs. 12,56±16,67; p-value=0,02), higher hypopnea index values (16,41±17,10 vs. 6,99±8,52; p-value=0,006) and lower minimum saturation (78,24±9,80 vs. 85,24±6,33; p-value=0,004). Conclusions: the high prevalence of OSAS found confirms its indication in the preoperative period of bariatric surgery. The main respiratory event involved in most individuals with OSAS was the hypopnea index.

Summary Introduction: The obstructive sleep apnea syndrome (OSAS) is a respiratory illness, characterized by recurrent episodes of apnea and hypopnea, leading to reduction or cessation of the airflow. Obesity is one of the major risk factors for the development of OSAS. To help in the diagnosis of this disease, easily applicable and low-cost questionnaries were developed, such as the Berlin Questionnaire (BQ). Objective: To evaluate the efficacy of the BQ for the screening of OSAS among candidates to bariatric surgery in a multidisciplinary preoperative program. Method: This is an observational, descriptive and cross-sectional study which evaluated obese individuals that were being prepared for bariatric surgery by means of the BQ. Results: BQ was able to detect that minimal variations in the body mass index, neck circumference and hip-to-waist ratio lead to changes in the risk to develop OSAS; the higher the values of these variables, the higher the risk for OSAS development. Conclusion: BQ was an efficient and reliable tool to demonstrate the high risk for OSAS development in individual with obesity.

<b><i>Background:</i></b> Obesity is associated with a higher risk of work disability and premature early retirement. <b><i>Objective:</i></b> The aim of this study was to examine psychosocial predictors for work ability prior to surgery. <b><i>Methods:</i></b> Based on a sample of 197 surgery-seeking obese patients (preoperative body mass index [BMI] above 35 kg/m<sup>2</sup>) from a German bariatric surgery unit, the present cross-sectional study examined based on standardized self-rating measures whether depressive symptoms, dysfunctional eating behaviors, relationship satisfaction, and life satisfaction have a predictive value for work ability. <b><i>Results:</i></b> Considerable impairment of work ability was found in 51.8% of morbidly obese participants (<i>n</i> = 102). Multiple regression analyses revealed that older age, greater depressive symptoms, and lower life satisfaction were significant predictors of preoperative work ability. BMI, gender, relationship satisfaction, and dysfunctional eating behaviors did not predict work ability. <b><i>Conclusions:</i></b> Our findings might indicate the use of further psychosocial measures following bariatric surgery to increase work ability.

Objective: To correlate anatomical and functional changes of the oral cavity, pharynx and larynx to the severity of obstructive sleep apnea syndrome (OSAS). Methods : We conducted a cross-sectional study of 66 patients of both genders, aged between 21 and 59 years old with complaints of snoring and / or apnea. All underwent full clinical evaluation, including physical examination, nasolarybgoscopy and polisonography. We classified individuals into groups by the value of the apnea-hypopnea index (AHI), calculated measures of association and analyzed differences by the Kruskal-Wallis and chi-square tests. Results : all patients with obesity type 2 had OSAS. We found a relationship between the uvula projection during nasoendoscopy and OSAS (OR: 4.9; p-value: 0.008; CI: 1.25-22.9). In addition, there was a major strength of association between the circular shape of the pharynx and the presence of moderate or severe OSAS (OR: 9.4, p-value: 0.002), although the CI was wide (1.80-53.13). The septal deviation and lower turbinate hypertrophy were the most frequent nasal alterations, however unrelated to gravity. Nasal obstruction was four times more common in patients without daytime sleepiness. The other craniofacial anatomical changes were not predictors for the occurrence of OSAS. Conclusion : oral, pharyngeal and laryngeal disorders participate in the pathophysiology of OSAS. The completion of the endoscopic examination is of great value to the evaluation of these patients.

Long Term Follow Up

Objective: The aim of this paper is to analyze the outcome of major comorbidities and body mass index during long-term follow-up in patients undergoing bariatric surgery. Material and methods: A retrospective cross-sectional study was conducted on a sample of 28 patients (32 women and 6 men; mean age: 43.52 years) undergoing bariatric surgery between 2008 and 2011. The surgical procedures performed were adjustable gastric banding (n =8), sleeve gastrectomy (n = 8) and gastric bypass (n = 22). Results: Diabetes mellitus was resolved in 73.43% of cases, hypertension in 47.05%, dyslipidemia in 75% and obstructive sleep apnea syndrome in 70%. Five years after surgery, 28.9% of the patients had obesity class I, 23.7% had overweight, 23.7% had obesity class II and 23.7% had obesity class III. Conclusion: bariatric surgery achieves resolution of comorbidities associated with obesity in a high percentage of cases. This effect is more effective in dyslipidemia. Weight regain in the long-term and follow-up beyond five years after surgery are still pending issues.

Abstract Background Obesity, through its numerous complications, influences the functional and vital prognosis, especially in situations of massive or morbid obesity. The aim of our study was to study the metabolic complications associated with obesity. Methods This was a descriptive cross-sectional study carried out in the first half of 2018 involving 100 obese patients attending the Obesity Unit of the National Institute of Nutrition in Tunis. Each patient received a complete clinical examination with a standard biological assessment. Obesity is defined by a body mass index ≥ 30 Kg / m2. Results The average age of our patients was 45.08 ± 13.9 years with a female predominance of 88%. The average weight was 103.76 ± 17.9 Kg. The average BMI was 38.95 ± 5.72 Kg / m2. The average waist circumference was 123.88 ± 13.13 cm and the average fat mass was 45.98 ± 12.22 kg. Twenty percent of our population was diabetic with an average duration of progression of 6.6. ± 4.04 years. The prevalence of dyslipidemia was high in morbidly obese patients with a rate of 18.6% compared to moderate to severe obesity at 6.4%. Arterial hypertension was noted in 33% of our population. The presence of moderate sleep apnea syndrome was noted in 31.3% of cases. Hyperuricemia was found in 8.6% of cases. Rheumatologic complications were marked by gonalgia in 26% of cases and low back pain in 6.8% of our patients. Conclusions Screening for complications related to obesity is necessary and essential for the comprehensive care of the obese person. Their treatment must be specific and it should not be limited to weight loss. Key messages Obesity. Metabolic complications.
