obesity, OSA

Obstructive sleep apnea (OSA) is a sleep-related breathing disorder associated with obesity markers such as neck circumference (NC), waist circumference (WC), and body mass index (BMI). A greater NC has been linked to a higher risk of OSA. To date, the largest reported NC has been 20.5 inches. We present a case of a patient who came to our clinic for OSA management and was found to have an NC of 25 inches, the largest reported to date. The primary objective of this case is to stimulate discussion and research on the specific limits of NC that indicate a higher risk of OSA, the impact of extreme obesity on the severity of the condition and its treatment challenges, and the importance of basic physical measurements of NC in assessing a patient's level of risk and providing appropriate care...

INTRODUCTION: Down syndrome (DS) is associated with multiple comorbid conditions and chronic immune dysfunction. Persons with DS who contract COVID-19 are at high risk for complications and have a poor prognosis. We aimed to study the clinical symptoms, laboratory and biochemical profiles, radiologic findings, treatment, and outcomes of patients with DS and COVID-19. METHOD: We systematically searched PubMed, MEDLINE, Web of Science, Scopus, and the Cochrane Library using the keywords COVID-19 or coronavirus or SARS-CoV-2 and DS or trisomy 21...

We investigated blood pressure (BP) variability as assessed by beat-to-beat, reading-to-reading and day-to-day BP variability indices in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). In 786 hospitalized hypertensives (mean age, 53.2 years; 42.2% women), we performed 10-min beat-to-beat (n = 705), 24-h ambulatory (n = 779), and 7-day home BP (n = 445) measurements and the full overnight polysomnography. Mild, moderate and severe OSAHS were defined as an apnea-hypopnea index of 5-14, 15-29, and ≥ 30 events per hour, respectively...

INTRODUCTION: Heavy truck drivers with untreated obstructive sleep apnea (OSA) are at higher risk of driving accidents. This study aims to estimate the prevalence of OSA and to identify the most frequent symptoms and comorbidities in heavy truck drivers. METHODS: This cohort study included the employees of a Portuguese transport company between 2019 and 2022. A home sleep apnea test (HSAT) was performed on all patients. SPSS® was used for statistical analysis, and a p-value lower than 0...

Obesity is the primary risk factor for the development of obstructive sleep apnea, and physical inactivity plays an important role. However, most studies have either only evaluated physical activity subjectively or objectively in obstructive sleep apnea. The objectives of this study were: (i) to assess the relationship between obstructive sleep apnea severity (both apnea-hypopnea index and desaturation parameters) and both objectively and subjectively measured physical activity after adjustment for anthropometry and body composition parameters; and (ii) to assess the relationship between objective and subjective physical activity parameters and whether obstructive sleep apnea severity has a modulatory effect on this relationship...

BACKGROUND AND AIMS: The use of a face mask while inducing general anaesthesia (GA) in obese patients is often ineffective in providing adequate ventilation. Although nasal mask ventilation has demonstrated effectiveness for continuous positive airway pressure (CPAP) in obese patients with obstructive sleep apnoea (OSA), it has not yet been applied to the induction of anaesthesia. This study evaluated the efficacy of nasal mask ventilation against standard face mask ventilation in anaesthetised obese patients with body mass index (BMI)>25 kg/m2 ...

Sleep apnea presents as recurrent respiratory arrests or shallow breathing during sleep, resulting in decreased oxygen saturation and sleep disruption. Among its various types, obstructive sleep apnea is the most common. Over the past few decades, the prevalence of sleep apnea has been on the rise, drawing increasing attention, particularly with the growing obesity and aging population. Prolonged exposure to a hypoxic environment due to sleep apnea not only damages multiple systems throughout the body but may also pose a threat to vision...

BACKGROUND: The prevalence of obstructive sleep apnea (OSA) is high among the bariatric surgery candidates. Obesity is the most important 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 5 years after the surgery. PATIENTS AND METHODS: In this prospective multicenter study, standard overnight cardiorespiratory recording was conducted to 150 patients at baseline prior to bariatric surgery...

Obstructive sleep apnea (OSA) is the most common sleep-disordered breathing disease. Continuous positive airway pressure (CPAP) is the gold standard for treatment, but compliance is suboptimal. Therefore, new therapeutic strategies need to be explored. OSA is often associated with multiple comorbidities, particularly type 2 diabetes and obesity. Effective weight loss is known to be crucial in reversing OSA and its associated comorbidities. However, sustained weight loss is difficult to achieve with lifestyle changes alone...

OBJECTIVE: Nocturnal symptoms are common in the asthmatic population, reflecting an exaggerated airway narrowing overnight due to several factors; it is questioned to what extent the awakenings documented in the clinical assessment of asthma control are due to the disease itself or to comorbidities. To answer this question, we aimed to evaluate to what proportion rhinitis, gastroesophageal reflux and the likelihood of being affected by OSAS were related to poor asthma control, by means of ACT evaluation...

OBJECTIVE: Obstructive sleep apnea (OSA) is a disorder characterized by disruption in breathing and hypoventilation. In parallel, metabolic syndrome (MetS) mainly co-occur with OSA, however, their association has not been fully elucidated. Therefore, this study aimed to reveal the relationship between OSA and MetS using data from the National Health And Nutrition Examination Survey (NHANES) database and pooled data from Genome-Wide Association Studies (GWAS). MATERIAL AND METHODS: Data from the National Health and Nutrition Examination Survey and pooled data from genome-wide association analysis (GWAS) were used univariate and multivariate logistic regression analyses were carried out to evaluate the correlation between OSA and MetS, and multivariate logistic regression models were utilized for adjusting for potential confounders...

INTRODUCTION: Obstructive sleep apnoea (OSA) and obesity commonly coexist. Weight loss and exercise are recommended management options for OSA. However, most of the current evidence on diet and OSA is focused on calorie restriction rather than diet quality. The aim of the present study was to determine the association of plant-based dietary indices (PDI) with OSA risk. METHODS: Cross-sectional data from 14 210 participants of the National Health and Nutrition Examination Survey who provided dietary information using the 24-hour recall method were used...

METHODS: This opinion article is a narrative review based on the expertise and consensus of a variety of key opinion leaders, in combination with an extensive literature review. This literature search included a thorough analysis of potential publications on both the PubMed Database and the Web of Science and was conducted between November 2022 and December 2022...

OBJECTIVE: Numerous studies have reported the close association of depression with obstructive sleep apnea (OSA). However, the causal nature and direction remain unclear. This study aimed to identify the genetic causal relationship between depression and OSA using Mendelian randomization (MR). METHODS: Based on publicly available genome-wide association studies data of depression and OSA, we conducted a bidirectional two-sample MR study. The inverse-variance weighted (IVW) was used as the main analysis method...

Objectives: Obstructive sleep apnea (OSA) is a prevalent sleep disorder that can increase the risk of hypertension, diabetes, obesity, and cardiovascular diseases. Hypoglossal nerve stimulation (HGNS) is an alternative therapy for OSA in patients who cannot tolerate continuous positive airway pressure. Understanding the impact of HGNS on blood pressure, hemoglobin A1C (A1C), and body mass index (BMI) currently remains limited. Methods: A retrospective review study of HGNS outcomes at a single practice from January 2020 to November 2022 was conducted...

OBJECTIVES: Noninvasive ventilation (NIV) is an effective treatment for chronic respiratory failure (CRF). Patient-centered outcomes need to be evaluated regularly and the S3 -NIV questionnaire seems an applicable tool. We translated this short, self-administered questionnaire into a Dutch version and tested its construct validity and reliability. METHODS: An observational study was conducted, including 127 stable long-term NIV users with CRF or complex sleep related breathing disorders due to different underlying diseases: chronic obstructive pulmonary disease (25%), slowly progressive neuromuscular disorders (35%), rapidly progressive neuromuscular disorders (12%) and 'other disorders' (28%) including complex sleep apnea and obesity hypoventilation syndrome...

Obstructive sleep apnea is a common comorbidity that occurs in individuals with obesity. It classically manifests with excessive daytime sleepiness, resulting in reduced quality of life, workplace productivity, and an increased risk of motor vehicle accidents. Weight gain plays an important role in its pathogenesis through worsening upper airway collapsibility, and current treatment options are targeted towards mechanically overcoming upper airway obstruction and weight loss. Continuous positive airway pressure therapy remains the most widely prescribed treatment for obstructive sleep apnea but poor tolerance is a common barrier to effective treatment...

Introduction Difficulties with tracheal intubation contribute to the morbidity and mortality associated with anesthesia. Suggested predictors for difficult airway include, history of obstructive sleep apnea, high Mallampati score, elderly, male, short neck, and high Wilson score. However, none of these has high diagnostic accuracy particularly in obese population. Parameters used to quantify obesity such as Body Mass Index(BMI), mid arm circumference, skin fold thickness, etc. have not been used as independent predictors of difficult airway...
