“…The proportions found regarding AHI agreed with the findings of Weingarten et al 16 , who classified 22.45% as non-apneic, 30.99% with mild apnea, 15.93% moderately apneic, and 30.61% affected by severe apnea. Aguiar et al 17 , on their turn, showed very similar values in all groups: 23.68% non-apneic patients, 26.31% with mild AHI, 23.68% moderately affected, and 26.31% with severe apnea. Finally, of the apneic patients studied by Tangerina et al 15 , 34.3% had mild disease, 25.7% moderate, and 40% severe ( Table 6 ).…”

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.

“…A ventilação mecânica não invasiva (VNI) é definida como um suporte ventilatório que não necessita de tubo orotraqueal (TOT) ou traqueostomia, utilizada por meio de uma interface, com o objetivo de promover a ventilação adequada, diminuir o trabalho respiratório, prevenir a fadiga muscular respiratória, aumentar a ventilação alveolar e melhorar as trocas gasosas, evitando, assim, a intubação e promovendo, em alguns casos, uma extubação precoce [8]. Considerando esses achados, é possível sugerir o uso da pressão positiva na via aérea superior (PAP), com a finalidade de melhorar os marcadores inflamatórios e a qualidade de vida [9]. Já a pressão positiva contínua nas vias aéreas (CPAP) é uma ferramenta que permite a oferta de ar em pressões maiores que a atmosférica [10].…”

Considerando a Síndrome de Hipoventilação da Obesidade (SHO) como potencialmente tratável, encontra-se dificuldade em comparar ensaios clínicos devido às diferentes titulações da ventilação mecânica não invasiva (VNI) e da pressão positiva contínua nas vias aéreas (CPAP). Objetivou-se realizar uma revisão integrativa da literatura com utilização de pressão positiva como método terapêutico. Foram incluídos ensaios clínicos randomizados, utilizando CPAP comparado a VNI como tratamento. A busca ocorreu nas bases de dados PubMed e Web of Science, incluindo-se estudos publicados entre 2008 e 2017. Foram selecionados 4 artigos, dois estudos comparando CPAP e binível. Apresentaram semelhança na melhora entre os grupos. O terceiro estudo comparou com grupo controle, sendo ambas eficientes em relação ao GC com melhora na PaCO2, Bic, sintomas clínicos, parâmetros polissonográficos e efeitos secundários. O quarto estudo apresentou para Suporte de Pressão Assegurada de Volume Médio (AVAPS-AE), eficácia de CPAP e binível na redução de surtos noturnos de pressão arterial. Dessa forma observa-se similar eficácia entre ambas as estratégias, e ambas são mais eficazes quando comparadas a um grupo controle.

Background: High neck circumference (NC) is associated with high burden diseases in Latin American and the Caribbean (LAC). NC complements established anthropometric measurements for early identification of cardio-metabolic and other illnesses. However, evidence about NC has not been systematically studied in LAC. We aimed to estimate the mean NC and the prevalence of high NC in LAC. Methods: We conducted a systematic review in MEDLINE, Embase, Global Health and LILACS. Search results were screened and studied by two reviewers independently. To assess risk of bias of individual studies, we used the Hoy et al. scale and the Newcastle-Ottawa scale. We conducted a random-effects meta-analysis. Results: In total, 182 abstracts were screened, 96 manuscripts were reviewed and 85 studies (n= 51,978) were summarized. From all the summarized studies, 14 were conducted in a sample of the general population, 23 were conducted with captive populations and 49 studies were conducted with patients. The pooled mean NC in the general population was 35.69 cm (95% IC: 34.85cm-36.53cm; I²: 99.6%). In our patient populations, the pooled mean NC in the obesity group was 42.56cm (95% CI 41.70cm-43.42cm; I²: 92.40%). Across all studied populations, there were several definitions of high NC; thus, prevalence estimates were not comparable. The prevalence of high NC ranged between 37.00% and 57.69% in the general population. The methodology to measure NC was not consistently reported. Conclusions: Mean NC in LAC appears to be in the range of estimates from other world regions. Inconsistent methods and definitions hamper cross-country comparisons and time trend analyses. There is a need for consistent and comparable definitions of NC so that it can be incorporated as a standard anthropometric indicator in surveys and epidemiological studies.
