STUDY OBJECTIVES To evaluate vitamin D (25(OH)D) levels in obstructive sleep apnea syndrome (OSAS) and possible relationships to OSAS severity, sleepiness, lung function, nocturnal heart rate (HR), and body composition. We also aimed to compare the 25(OH)D status of a subset of OSAS patients compared to controls matched for important determinants of both OSAS and vitamin D deficiency (VDD). M...

background and objective: obstructive sleep apnea syndrome (osas) is a prevalent disease in adults. limited evidence regarding the effect of severity of sleep apnea and depression on heart rate variability (hrv) indices exists. hence, we decided to focus on the association between hrv and severity of osas based on depression score. materials and methods: a total of 193 patients with confirmed o...

BACKGROUND Obstructive sleep apnea syndrome (OSAS) is associated with cardiovascular diseases, in particular systemic arterial hypertension. We postulated that intermittent nocturnal hypoxia in OSAS may be associated to decreased fractional exhaled nitric oxide (FENO) levels from distal airspaces. METHODS Multiple flow rate measurements have been used to fractionate nitric oxide (NO) from alv...

INTRODUCTION The aim of this study was to evaluate the serum paraoxonase (PON), arylesterase activities, lipid hydroperoxide (LOOH), sulfhydryl (-SH), and ceruloplasmin (Cp) levels, total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) in adults with obstructive sleep apnea syndrome (OSAS) and to determine whether these oxidant and antioxidant levels can b...

OBJECTIVE To investigate the impact of obstructive sleep apnea syndrome (OSAS) on night-time secretion of brain natriuretic peptide (BNP) and antidiuretic hormone (ADH) in older men with nocturia accompanied by nocturnal polyuria. MATERIALS AND METHODS One hundred six men with nocturia aged ≥ 60 years underwent full-night polysomnography to determine whether they had OSAS. Blood count, standa...

Hội chứng ngưng thở khi ngủ tắc nghẽn (OSAS) là bệnh lý có tần suất mắc khá phổ biến nhưng thường bị bỏ qua và ít được quan tâm. Bệnh do nhiều nguyên nhân gây nên thể đơn độc hay phối hợp. Chẩn đoán không phải quá khó nếu điều trị các nghiêm trọng, đặc biệt trên tim mạch mà rối loạn nhịp vai trò chủ yếu trong việc tử vong cố ở OSAS. Việc OSAS trước hết giải quyết sau đó mới theo hướng dẫn phù

Children with the obstructive sleep apnea syndrome (OSAS) have impaired respiratory afferent cortical processing during sleep that persists after treatment of OSAS. However, it is unknown whether this impairment is present during wakefulness and, if so, whether it improves after OSAS treatment. We hypothesized that children with OSAS, during wakefulness, have abnormal cortical processing of res...

The aim of this study was to review the literature to evaluate the association between allergic rhinitis (AR) and obstructive sleep apnea syndrome (OSAS) in childhood. A PubMed literature search (January 1970 to February 2005) was conducted using the following key words: obstructive sleep apnea, allergic rhinitis, and mouth breathing. The retrieved articles were reviewed and the levels of evide...

OBJECTIVE A consensus has not been reached regarding the association of several different gene polymorphisms and susceptibility to obstructive sleep apnea syndrome (OSAS). We performed a meta-analysis to better evaluate the associations between 5-HT2A, 5-HTT, and LEPR polymorphisms, and OSAS. METHOD 5-HT2A, 5-HTT, and LEPR polymorphisms and OSAS were identified in PubMed and EMBASE. The poole...
