INTRODUCTION: Obesity is associated with significantly better outcome after acute myocardial infarction (AMI), a phenomenon known as 'obesity paradox'. Tricuspid annular plane systolic excursion (TAPSE) is an echocardiographic measurement of right ventricular (RV) function and has prognostic implications at the time of AMI. METHODS: We examined the difference in RV function among patients admitted with AMI according to obesity status. In a single center cohort analysis of 105 patients admitted between 2010 and 2011 with the diagnosis of AMI...

Objective: To study the relationship between dilated cardiomyopathy and obstructive sleep apnea-hypopnea syndrome (OSAHS) and to evaluate the curative effects of continuous positive airway pressure (CPAP) in OSAHS complicated with dilated cardiomyopathy. Methods: We reported one case with the symptom of exertional dyspnea for 1 year and aggravating for 1 month. The patient finally was diagnosed with severe OSAHS complicated with dilated cardiomyopathy leading to pulmonary hypertension. A systematic literature review was performed for similar published cases in Pubmed, Wanfang and CNKI database, using the keywords (obstructive sleep apnea) OR(OSA) OR(OSAHS) AND(dilated cardiomyopathy OR DCM)from January 1990 to May 2016...

STUDY OBJECTIVES: Obesity and regional fat distribution, measured by neck fat mass percentage using dual-energy X-ray absorptiometry (DXA), correlate with obstructive sleep apnea (OSA) severity in adults. In obese children, neck-to-waist-circumference ratio predicts OSA. This study examined associations between body fat percentage and distribution and sleep-disordered breathing (SDB) severity in obese youth, measured with DXA. METHODS: Cross-sectional retrospective study conducted at a tertiary children's hospital...

Pregnancy, particularly late gestation, has been associated with a relatively high prevalence of obstructive sleep apnea (OSA). Intermittent hypoxia (IH), a hallmark of OSA, could impose significant long-term effects on somatic growth, energy homeostasis, and metabolic function in offspring. We hypothesized that IH during late pregnancy (LG-IH) may increase the propensity for metabolic dysregulation and obesity in adult offspring via epigenetic modifications. Time-pregnant female C57BL/6 mice were exposed to LG-IH or room air (LG-RA) during days 13-18 of gestation...

BACKGROUND: In moderately to severely obese patients with obstructive sleep apnea (OSA), the effects of long-term positive airway pressure (PAP) treatment on cardiovascular risk are poorly defined. PURPOSE: To assess the effect of continuous positive airway pressure (CPAP) or noninvasive ventilation (NIV) on the occurrence of cardiovascular events in obese OSA patients. METHODS: We performed a noninterventional observational study in obese OSA patients recruited between 2007 and 2010 at the Sleep Center, University of Grenoble, treated with CPAP or NIV, and followed for 5...

PURPOSE: Obesity is commonly associated with poor sleep, excessive daytime sleepiness (EDS) and depressive mood but the impact of bariatric surgery on these conditions is incompletely understood. This study aimed to investigate the course of EDS and sleep quality in bariatric surgery patients in relation with changes in body weight and depressive symptoms. METHODS: In patients consecutively submitted to bariatric surgery, baseline and postoperative sleep quality were evaluated by the Pittsburgh Sleep Quality Index (PSQI), excessive daytime sleepiness by the Epworth Sleepiness Scale (ESS), risk for OSA by the Berlin Questionnaire (BQ), and depressive symptoms by the Beck Depression Inventory-Short Form (BDI)...

BACKGROUND: Obstructive sleep apnea (OSA) is associated with the progression of non-alcoholic fatty liver disease (NAFLD) to steatohepatitis and fibrosis. This progression correlates with the severity of OSA-associated hypoxia. In mice with diet induced obesity, hepatic steatosis leads to liver tissue hypoxia, which worsens with exposure to intermittent hypoxia. Emerging data has implicated hepatocyte cell signaling as an important factor in hepatic fibrogenesis. We hypothesized that hepatocyte specific knockout of the oxygen sensing α subunit of hypoxia inducible factor-1 (HIF-1), a master regulator of the global response to hypoxia, may be protective against the development of liver fibrosis...

Obstructive sleep-disordered breathing (SDB) can result in cardiovascular and neurocognitive morbidity as well as adversely affect behavior, growth, quality of life, and nocturnal continence. This article summarizes the latest evidence regarding the morbidity related to obstructive SDB, commenting on the impact of severity of obstruction, that is, the difference in effects seen of moderate to severe obstructive sleep apnea syndrome (OSAS) compared to those of mild OSAS or primary snoring. The impact of therapy is discussed, focusing on which children are likely to benefit from treatment interventions; namely those with moderate or severe OSAS irrespective of the presence of morbidity, children with mild OSAS with associated morbidity or predictors of SDB persistence such as obesity, and children with complex conditions accompanied by upper airway obstruction like craniosynostosis and Prader-Willi syndrome...

BACKGROUND: Morbidly obese patients with excessive concomitant disease carry a significantly increased perioperative risk. Although they may benefit most from a bariatric intervention, they are often denied surgery. Laparoscopic sleeve gastrectomy (LSG), as it is less complication-prone than other bariatric procedures, suits the needs of those patients. OBJECTIVE: To review the short-term outcome of LSG for high-risk patients SETTING: University hospital, Switzerland...

INTRODUCTION: Pediatric obesity is a leading risk factor for obstructive sleep apnea (OSA), a condition commonly treated with adenotonsillectomy (T&A). It has been hypothesized that obesity increases a child's risk of failing T&A for OSA, however this relationship has not yet been quantified. The primary objective of this study was to investigate the relationship between obesity as measured by perioperative Body Mass Index (BMI) and persistent OSA following T&A as measured by polysomnography (PSG)...

BACKGROUND: Obstructive sleep apnea (OSA) is now being recognized as an additional contributing factor to the pathogenesis of obesity-related comorbidities. At the same time, there is now increasing evidence to suggest that intestinal wall permeability plays a role in the development of metabolic syndrome. In the present study, circulating zonulin and fatty acid binding protein (I-FABP) were measured in association with metabolic, hepatic, and inflammatory parameters. RESULTS: Compared with controls, plasma I-FABP levels were significantly higher in patients with OSA (571 pg/mL [IQR 290-950] vs 396 pg/mL [IQR 234-559], p = 0...

Obstructive sleep apnoea (OSA), common in children with obesity, is associated with cardiovascular morbidity. Autonomic dysfunction has been suggested to be a key player in the development of these complications. We investigated the relationship between obesity, OSA and sympathetic activity in children. 191 children with obesity were included and distributed into two groups: 131 controls and 60 with OSA. Beat-to-beat RR interval data were extracted from polysomnography for heart rate variability analysis. Urinary free cortisol levels were determined...

The diagnosis and management of obstructive sleep apnea (OSA) are increasingly being performed in the home. In the home management pathway, patients with high pretest probability for OSA are first tested using home sleep apnea testing and if positive for OSA, are treated with automatic positive airway pressure (APAP). The home management pathway has been validated by multiple investigators1-3 and is considered an alternative pathway in guidelines for the evaluation and management of OSA.4 However, there are limitations to the routine use of this pathway...

OBJECTIVE: The aim of this study was to evaluate the effect of one-year useful continuous positive airway pressure (CPAP) treatment on serum vitamin D levels in middle-aged men affected by obstructive sleep apnea syndrome (OSAS). METHODS: This is a secondary investigation related to a previously published observational study about the effect of short-term CPAP therapy on serum vitamin D levels in severe OSAS (Apnea-Hypopnea Index - AHI- >30/h) patients. In the present study, we included patients participating to the previous investigation who repeated serum vitamin D assessment after one year of useful CPAP treatment, and compared to control a group of OSAS patients with scarce compliance to CPAP treatment...

Obstructive sleep apnoea (OSA) is associated with a rise in cardiovascular risk in which increased sympathetic activity and depressed baroreceptor reflex sensitivity (BRS) have been proposed. We examined this association in a sample of healthy elderly subjects with unrecognised OSA. 801 healthy elderly (aged ≥65 years) subjects undergoing clinical, respiratory polygraphy and vascular assessment were examined. According to the apnoea-hypopnoea index (AHI), the subjects were stratified into no OSA, mild-moderate OSA and severe OSA cases...

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is an effective treatment for morbid obesity resulting in approx. 70% excess weight loss (EWL) at 1-2 years. The aim of this study was to identify factors predictive of inadequate EWL following primary LRYGB. METHODS: Data on consecutive patients who underwent primary LRYGB between September 2009 and March 2013 were collected prospectively. The effects of age, gender, baseline body mass index (BMI), preoperative EWL, length of time between initial consultation and surgery (TtS), presence of diabetes mellitus (DM), arthritis, obstructive sleep apnea (OSA) and postoperative length of hospital stay (LOS) on EWL at 12 months were studied...
