The incidence of cardiovascular disease and mortality rates are high among patients with left ventricular hypertrophy (LVH). Obstructive sleep apnea (OSA) has been reported to increase left ventricular mass (LVM) and cause LVH. The prevalence of hypertension, a major cause of increased LVM, is high in OSA; however, it is still unknown whether OSA is an independent factor that increases LVM in addition to triggering LVH. This study investigated out-of-office blood pressure (BP) via ambulatory BP monitoring (ABPM) in patients with OSA diagnosed by polysomnography (PSG) and sought to determine the effects of OSA and hypertension on LVM...

The classical definition of Chronic Obstructive Pulmonary Disease (COPD) as a lung condition characterized by irreversible airway obstruction is outdated. The systemic involvement in patients with COPD, as well as the interactions between COPD and its comorbidities, justify the description of chronic systemic inflammatory syndrome. The pathogenesis of COPD is closely linked with aging, as well as with cardiovascular, endocrine, musculoskeletal, renal, and gastrointestinal pathologies, decreasing the quality of life of patients with COPD and, furthermore, complicating the management of the disease...

Among patients with sleep apnea the reported prevalence of precapillary pulmonary hypertension (PH) has varied largely, depending on patient selection, disease definition, and associated conditions, in particular chronic pulmonary disease. However, in the absence of comorbidities, PH seems to be rare in patients with sleep apnea. Conversely, sleep-related breathing disorders have been commonly found in patients with PH and they have been associated with an impaired quality of life. Since sleep-related breathing disorders may affect the pulmonary circulation and vice versa, patients with sleep-related breathing disorders should be evaluated for risk factors, symptoms and clinical signs of PH and right ventricular heart failure and patients with PH should be evaluated for sleep apnea...

Purpose. To evaluate alteration in serum TSH in hypertensives with OSA and its relation with cardiometabolic risk factors. Methods. 517 hypertensives were cross-sectionally studied. OSA was determined by polysomnography and thyroid function by standard methods. Results. OSA was diagnosed in 373 hypertensives (72.15%). Prevalence of subclinical hypothyroidism was significantly higher in OSA hypertensives than in non-OSA ones (15.0% versus 6.9%, P = 0.014). Serum LnTSH in hypertensives with severe OSA was significantly higher (0...

Sleeve gastrectomy (SG) has become one of the most commonly used bariatric procedures worldwide. However, data regarding long-term results remain insufficient. The aim of this study was to review the long-term results after SG. We conducted a comprehensive literature search of Medline and the Cochrane Library for articles published until May 2016 on the long-term results (>5 yr) after SG. Studies representing outcomes of SG were included if they reported≥5-year results that contained at least one outcome of interest-weight loss, co-morbidities, long-term complications, or quality of life-and SG was performed as a primary procedure...

Objective: To assess the association between daytime sleepiness and hypertension among patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods: A total of 1 958 patients from Sleep Medicine Center of West China Hospital between January 2015 and January 2016 were included in the study. All subjects underwent one night polysomnography (PSG) and Epworth sleep scale (ESS) was estimated. The patients were divided into non-OSAHS group[apnea-hypopnea index (AHI)<5/h]and OSAHS group (AHI≥5/h) based on PSG, and then OSAHS group was further divided into those with and without daytime sleepiness groups according to ESS score (the cut point of ESS was 14)...

The control mechanisms of respiration as a vital function are complex: voluntary - cortical, and involuntary - metabolic, neural, emotional and endocrine. Hormones and hypothalamic neuropeptides (that act as neurotrasmitters and neuromodulators in the central nervous system) play a role in the regulation of respiration and in bronchopulmonary morphology. This article presents respiratory manifestations in adult endocrine diseases that evolve with hormone deficit or hypersecretion. In hyperthyroidism, patients develop ventilation disorders, obstructive and central sleep apnea, and pleural collection...

Behrouz Jafari, Vahid Mohsenin
BACKGROUND: Obstructive sleep apnea (OSA) is a highly prevalent disorder affecting 15-24% of adults and triples the risk for hypertension independent of other risk factors. The exact mechanisms of endothelial dysfunction and variable susceptibility to hypertension in OSA are not entirely clear. No biomarker to date has been found to be associated with hypertension in OSA. Chitinase-3-like protein-1(YKL-40) is a circulating moiety with roles in injury, repair and angiogenesis that is dysregulated in atherosclerosis and correlates with increased cardiovascular morbidity and mortality...

: Obstructive sleep apnea (OSA) is characterized by repeated involuntary closure of the pharyngeal airspace during sleep. Normal activity of the genioglossus (GG) muscle is important in maintaining airway patency, and inhibition of GG activity can contribute to airway closure. Neurons in the hypoglossal motor nucleus (HMN) regulate GG activity. Adrenergic tone is an important regulator of HMN neuronal excitability. In laboratory models α1-adrenergic antagonists inhibit HMN neurons and GG activity, suggesting that α1-adrenergic antagonism might adversely affect patients with OSA...
