Obesity and Obstructive Sleep Apnea

2021

Obstructive sleep apnea (OSA) is characterized by upper airway collapse during sleep. Chronic intermittent hypoxia, sleep fragmentation, and inflammatory activation are the main pathophysiological mechanisms of OSA. OSA is highly prevalent in obese patients and may contribute to cardiometabolic risk by exerting detrimental effects on adipose tissue metabolism and potentiating the adipose tissue dysfunction typically found in obesity. This chapter will provide an update on: (a) the epidemiological studies linking obesity and OSA; (b) the studies exploring the effects of intermittent hypoxia and sleep fragmentation on the adipose tissue; (c) the effects of OSA treatment with continuous positi…

Blood pressure reduction following treatment with positive airway pressure in sleep apnea: data from the European Sleep Apnea Database

2020

Abstract Introduction Positive airway pressure (PAP) treatment modifies blood pressure (BP) in patients with obstructive sleep apnea (OSA). We aimed to explore which factors that influence the BP response to PAP therapy in the European Sleep Apnea Database (ESADA). Methods A total of 2662 OSA patients with PAP therapy ≥90 days were included in the analysis (74% male, age 55±11 years, body mass index 32.3±6.1 kg/m2, 47% hypertensives, apnea-hypopnea index 40±24 events/h, treatment duration 1.0±1.1 years, PAP compliance 5.2±1.9 h/day). Anthropometric data, co-medications and office BP were assessed at baseline and follow-up visit. Results Systolic and diastolic BP were modestly reduced after …

Our Assessment Using Palate Postoperative Problems Score (PPOPS): Tool for the Evaluation of Results in Palatal Surgery Techniques

2018

Obstructive sleep apnoea syndrome is a chronic condition characterized by frequent episodes of collapse of upper airways during sleep. Prevalence of the disease is settled at about 3–7%. Today, palatal surgery is a reference point in OSAHS treatment and there are many different surgical techniques. The purpose of our work is to compare post-operative results of palate surgery techniques used in our practice in OSAHS patients, studying the degree of patients’ satisfaction with a recent score recommended by Rashwan et al. called PPOPS (Palate Post-Operative Problems Score). A retrospective study was performed on a sample of 40 patients subject to different palate surgery techniques for OSAS. …

Obstructive Sleep Apnea and Snoring

2017

Moderate-to-severe sleep-disordered breathing (SDB) is common in the general population, particularly between ages 50 and 70. Obstructive sleep apnea (OSA) is a major public health concern presenting a high associated risk for hypertension, cardiovascular disease, type II diabetes, and motor vehicle accidents. The dentist should always evaluate for the presence of risk factors in patients with any signs of SDB. PSG is the gold standard for the diagnosis of OSA and sleep disorders. The CPAP device is still considered the most effective therapeutic approach for the management of SDB in both adults and children; however, their side effects and low adherence make clinicians look for alternative…

Prevalence of physician-diagnosed asthma in patients with suspected obstructive sleep apnea syndrome: A cross-sectional analysis of the ESADA database

2015

It has been reported that bronchial asthma is often associated with obstructive sleep apnea (OSA) and daytime sleepiness. We analyzed the prevalence of physician-diagnosed asthma in 4929 subjects with suspected obstructive sleep apnea (OSA) in the European Sleep Apnea database (ESADA) Cohort. Patients were studied by respiratory polygraphy (PG: n=1624, 66.6% males) or full polysomnography (PSG: n=3305, 70.4% males), and the clinical characteristics of asthmatic (A) and non-asthmatic (non-A) patients were analyzed according to OSA severity. Significance was at p 2 , p=0.0004) and showed more severe daytime sleepiness (Epworth score: 10.4±5.6 vs 9.5±5.3, p=0.0015) and a trend for worse noctur…

Hypoxic burden and angiogenic factors in patients with myocardial infarction and obstructive sleep apnea

2019

Introduction: The amount and severity of hypoxia have been related to risk of cardiovascular events. Aim: To determine the relationship between nocturnal hypoxic burden and pro- angiogenic factors in patients with obstructive sleep apnea (OSA) and myocardial infarction (MI). Method: A prospective, observational study in patients with a first acute MI. Eligible patients underwent a polysomnography within 30 days after MI, and a serum blood sample was drawn in order to measure a panel of angiogenic factors by Luminex technology. A hypoxic burden index (HBI) was calculated as the integral area under the desaturation curve (obtained by calculating the integral of the oxygen saturation reduction…

A conservative treatment for chronic obstructive sialoadenitis by intraductal instillation of mucolytic, steroids and antibiotic solution

2021

Abstract Purposes Reporting our experience in treating chronic obstructive sialadenitis with a protocol consisting of sialoendoscopy and intraductal instillation of antibiotics, steroids and n-acetyl-cysteine (NAC) solution. Methods Prospective study of patients with chronic obstructive sialadenitis with no apparent lithiasic obstructions, with recurrent non-lithiasic sialoadenitis and patients with lithiasic sialoadenitis not solved with sialoendoscopy. In all cases, a sialoendoscopy was performed. All the patients affected by lithiasic sialoadenitis where the chronic inflammation was resolved with sialoendoscopy were excluded from the study. The mid-term follow-up was performed at 12 mont…

New developments in optimizing bronchodilator treatment of COPD: a focus on glycopyrrolate/formoterol combination formulated by co-suspension deliver…

2018

COPD causes considerable health and economic burden worldwide, with incidence of the disease expected to continue to rise. Inhaled bronchodilators, such as long-acting muscarinic antagonists (LAMAs) and long-acting β2-agonists (LABAs), are central to the maintenance treatment of patients with COPD. Clinical studies have demonstrated that combined LAMA + LABA therapies improve efficacy while retaining a safety profile similar to LAMA or LABA alone. This has led to the development of several LAMA/LABA fixed-dose combination (FDC) therapies, which provide patients with the convenience of two active compounds in a single inhaler. GFF MDI (Bevespi Aerosphere®) is an FDC of glycopyrrolate/formote…

Asthma-COPD overlap syndrome: recent advances in diagnostic criteria and prognostic significance.

2017

The term asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) has been proposed for individuals with features of both asthma and COPD. Several attempts have been done to define ACOS on the basis of medical history, symptoms, and functional findings. The main diagnostic criteria include airflow obstruction with a strong although incomplete reversibility to bronchodilation tests, a significant exposure to cigarette or biomass smoke, and a history of atopy or asthma. Additional diagnostic elements include eosinophilic airway and systemic inflammation, a good response to corticosteroid treatment, and a high concentration of exhaled nitric oxide. ACOS should be distinguish…
