BACKGROUND: Obstructive sleep apnea (OSA) is a highly prevalent sleep disorder, particularly in bariatric patients. It is known to be tightly linked with metabolic abnormalities and cardiovascular morbidity. Obesity is the most noteworthy individual risk factor for OSA. The aim of this study was to investigate the effect of a laparoscopic Roux-en-Y gastric bypass (LRYGB) on OSA one year after surgery. METHODS: In this prospective multicenter study standard overnight cardiorespiratory recording was conducted 12 months after bariatric surgery in 132 patients who had OSA in the baseline recording prior to the operation...

OBJECTIVE: Body mass index (BMI) has been shown to be strongly correlated with severity of OSA. However, BMI has not been shown to be correlated with sleep apnea in all patients studied. The purpose of this study was to evaluate the relationship between various anthropometric measures and severity of OSA according to BMI in men. METHODS: We conducted a retrospective analysis of the medical records of patients who visited for evaluation of OSA. Polysomnography results, height, weight, neck circumference, waist circumference, and hip circumference were obtained in all subjects...

HIV-associated lipodystrophy syndrome (HALS) is characterized by body fat redistribution as a consequence of the antiretroviral therapy (ART) introduction, associated with an increased risk of cardiovascular disease development. Subjective diagnosis, classified between three subtypes according to the body region on which fat is lost and/or accumulated, named lipoatrophy, lipohypertrophy, and mixed lipodystrophy, is possibly accompanied with metabolic alterations. Forty people living with HIV/AIDS (PLHA), with clinical diagnosis of HALS and from both genders, were assessed...

CONTEXT: The increased fracture risk associated with type 1 diabetes mellitus (T1DM) remains unexplained by traditional risk factors such as low areal bone mineral density (aBMD). Nonetheless, few data exist on other determinants of bone strength in T1DM, including volumetric BMD (vBMD) and bone geometry. OBJECTIVE: We compared areal and volumetric bone parameters and cortical bone geometry in adult T1DM patients and gender- and age-matched controls. DESIGN: Cross-sectional study including 64 adult T1DM patients (38 men, 41...

The combination of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) is associated with substantial morbidity and mortality. We hypothesized that predictors of OSA among patients with COPD may be distinct from OSA in the general population. Therefore, we investigated associations between traditional OSA risk factors (e.g. age), and sleep questionnaires [e.g. Epworth Sleepiness Scale] in 44 patients with advanced COPD. As a second aim we proposed a pilot, simplified screening test for OSA in patients with COPD...

BACKGROUND: The greater omentum is supplied by the right, middle, and left omental arteries, which arise from the right and left gastroepiploic arteries. All or part of the greater omentum can be harvested based on this blood supply for free tissue transfer. It has stimulated new interest in its use as the donor site in the treatment of lymphedema. For patients who have failed other management options or have limited peripheral lymph node donor sites, the greater omental lymph node flap may offer the best chance for lymphedema treatment...

Obstructive sleep apnea syndrome (OSAS) is a common clinical condition. The way that OSAS risk factors associate and converge is not a random process. As such, defining OSAS phenotypes fosters personalized patient management and population screening. In this paper, we present a network-based observational, retrospective study on a cohort of 1,371 consecutive OSAS patients and 611 non-OSAS control patients in order to explore the risk factor associations and their correlation with OSAS comorbidities. To this end, we construct the Apnea Patients Network (APN) using patient compatibility relationships according to six objective parameters: age, gender, body mass index (BMI), blood pressure (BP), neck circumference (NC) and the Epworth sleepiness score (ESS)...

BACKGROUND: The objective of the study was to investigate the association of neck circumference (NC) to parameters of glucose homeostasis compared to classical anthropometric parameters of lean and obese children. METHODS: Three dimensional (3D)-body scanning quantified anthropometric (height, weight, NC, hip/waist circumference, BMI) and metabolic parameters (fasting plasma glucose [FPG], insulin, HbA1c, oGTT, HOMA-IR) were determined cross-sectionally in 1542 participants (5-18 years)...

To develop an applicable prediction for obstructive sleep apnea (OSA) is still a challenge in clinical practice. We apply a modern machine learning method, the support vector machine to establish a predicting model for the severity of OSA. The support vector machine was applied to build up a prediction model based on three anthropometric features (neck circumference, waist circumference, and body mass index) and age on the first database. The established model was then valided independently on the second database...

Soft and rigid tissue mass prediction equations have been previously developed and validated for the segments of the upper and lower extremities in living humans using simple anthropometric measurements. The reliability of these measurements has been found to be good to excellent for all measurement types (segment lengths, circumferences, breadths, skinfolds). However, the reliability of the measurements needed to develop corresponding equations for the head, neck and trunk has yet to be determined. The purpose of this study was to quantify the inter- and intra-measurer reliability of 34 surface anthropometric measurements of the head, neck and trunk segments...

PURPOSE: To analyse the short-term effectiveness of an intensive multidimensional inpatient programme specifically developed for patients with severe obesity. METHODS: A multidisciplinary team managed a 3-week residential programme characterised by the integration of nutritional and physical rehabilitation with psychological and educational intervention. All patients consecutively admitted in 10 months were analysed at admission and discharge for changes in the following domains: anthropometry (weight, body mass index (BMI), waist and neck circumferences), cardiovascular risk factors (glycaemia, HbA1c, lipid profile, blood pressure), quality of life, eating behaviour, and physical performance (VO2peak by incremental cycle ergometer test, 6-min walking test (6MWT), chair stands test)...

Background: Neck circumference (NC) is a predictor of cardiometabolic risk. The objective of this study was to explore the relationship of NC to muscle sympathetic nerve activity (MSNA) within an overweight and obese population. Methods: The study design was a retrospective cross-sectional analysis. Un-medicated persons (72 men, 53 postmenopausal women) aged 56 ± 1 years (mean ± SEM) with body mass index (BMI) 32.8 ± 0.4 kg/m(2), were studied. NC was measured together with traditional anthropometric measures, supine blood pressure, fasting blood lipids, insulin, and glucose...

BACKGROUND: Screening instruments for obstructive sleep apnea (OSA), as used routinely to guide clinicians regarding patient referral for polysomnography (PSG), rely heavily on symptomatology. We sought to develop and validate a cerebrovascular disease-specific OSA prediction model less reliant on symptomatology, and to compare its performance with commonly used screening instruments within a population with ischemic stroke or transient ischemic attack (TIA). METHODS: Using data on demographic factors, anthropometric measurements, medical history, stroke severity, sleep questionnaires, and PSG from 2 independently derived, multisite, randomized trials that enrolled patients with stroke or TIA, we developed and validated a model to predict the presence of OSA (i...

Obstructive sleep apnea (OSA) is the leading sleep disordered breathing condition, with a prevalence rate of moderate to severe OSA of approximately 10 - 17% in the general population. Its prevalence in the surgical population seems to be higher. However, a proportion of up to 60% of patients may not have a formal diagnosis at the moment of preoperative visit. OSA is associated with a number of comorbidities and increased perioperative risks. However, most interventions for the perioperative management of OSA patients lack high quality evidence...

OBJECTIVE: Obstructive sleep apnea (OSA) has been identified as the most common secondary contributing factor for the development and worsening of hypertension. However, the underlying relationships between blood pressure variability (BPV) and OSA are still not very clear. Therefore, we investigated the influences of OSA on BPV in hypertensive patients and explored the potential pathophysiologic mechanisms. PARTICIPANTS AND METHODS: Ambulatory blood pressure (BP) monitoring was carried out and polysomnography was performed to detect sleep apnea...

Obstructive sleep apnoea (OSA) is known to commonly co-exist with primary aldosteronism (PA), but it is unknown if treatment of PA improves sleep apnoea parameters in these patients. We therefore aimed to determine whether specific medical or surgical treatment of PA improves OSA, as measured by the apnoea-hypopnoea index (AHI). We recruited patients undergoing diagnostic workup for PA if they had symptoms suggestive of OSA. Patients with confirmed PA underwent polysomnography (PSG) at baseline and again at least 3 months after specific treatment for PA...

OBJECTIVE: Although many studies worldwide have focused on the relationship between vitamin D and insulin resistance, results remain controversial. Furthermore, concentrations of serum 25-hydroxyvitamin D (25(OH)D) in the Chinese population are unclear. We aimed to investigate vitamin D status and its correlation with insulin resistance among a Chinese adult population. DESIGN: Serum 25(OH)D, fasting blood glucose, fasting insulin, glycated Hb (HbA1c) and other metabolic parameters were assessed...
