Treatment options in obstructive sleep apnea

2022

AbstractTreatment of OSA with CPAP is currently the recommended treatment and has the greatest evidence of efficacy on AHI, symptoms and comorbidities. Symptomatic patients with moderate-severe OSA generally have good adherence to CPAP therapy, while those with mild OSA, female, young and generally paucisymptomatic, have lower CPAP adherence, especially in the medium and long term. The recent identification of different clinical and pathophysiological phenotypes of OSA has paved the way for alternative treatments to CPAP, leading to an increasingly personalized therapy. Weight loss and lifestyle modifications are highly recommended in all obese or overweight patients. Mandibular advancement…

Differential electrodermal and phasic heart rate responses to personally relevant information: Comparing sleep and wakefulness

2010

This study examined autonomic physiological responses to personally relevant information presented during sleep and wakefulness. Heart rate and electrodermal reactions to subjects’ own first name and other first names were measured during sleep stage 2, rapid eye movement (REM) sleep, and wakefulness. Across all conditions, larger skin conductance responses were elicited by subjects’ own first name. During REM sleep, personally relevant information led to larger heart rate acceleration, whereas an enhanced deceleration was examined during wakefulness. These findings suggest that auditory information is processed on a semantic level even during sleep. However, personally relevant information…

Possible Role of Glymphatic System of the Brain in the Pathogenesis of High-Altitude Cerebral Edema

2018

Simka, Marian, Paweł Latacz, and Joanna Czaja. Possible role of glymphatic system of the brain in the pathogenesis of high-altitude cerebral edema. High Alt Med Biol. 19:394–397, 2018.—In this article, we suggest that the glymphatic system of the brain can play an important role in the pathogenesis of high-altitude cerebral edema (HACE). Water enters the intercellular space of the brain primarily through aquaporin-4 (AQP-4) water channels, the main component of the glymphatic system, whereas acetazolamide, pharmacological agent used in the prevention of HACE, is the blocker of the AQP-4 molecule. In animal experiments, cerebral edema caused by hypobaric hypoxia was associated with an increa…

Sleep quality does not mediate the association between chronodisruption and metabolic syndrome

2020

ABSTRACTAimsThe objective of the present work was to determine to what extent sleep quality may mediate the association between CD, metabolic syndrome (MS) and body composition (BC).MethodologyCross-sectional study which included 300 adult health workers, 150 of whom were night shift workers and thereby exposed to CD. Diagnosis of MS was made based on Adult Treatment Panel III criteria. Sleep quality was measured using the Pittsburgh Sleep Quality Index. Body mass index (BMI), fat mass percentage, and visceral fat percentage were measured as indicators of BC. Data were analyzed using logistic, linear regression and structural equation models.ResultsThe odds of health workers exposed to CD t…

The Influence of Sports on Cognitive Task Performance – A Critical Overview

2013

The potential effect of different methods on cognitive performance is of great interest to scientific researchers. In addition to drugs, nutrition and sleeping behavior, extensive research has focused on different kinds of sports and exercise and their potential to enhance cognitive task performance. In this chapter, I will give the reader an overview of studies dealing with athletic activities of healthy people and their effects on cognitive task performance. Furthermore, I present and discuss limitations and problems found in these studies. One problem that I point out that makes the comparison of the study results difficult is the heterogeneous study design regarding mode, duration and i…

Non Linear Fitting Methods for Machine Learning

2017

This manuscript presents an analysis of numerical fitting methods used for solving classification problems as discriminant functions in machine learning. Non linear polynomial, exponential, and trigonometric models are mathematically deduced and discussed. Analysis about their pros and cons, and their mathematical modelling are made on what method to chose for what type of highly non linear multi-dimension problems are more suitable to be solved. In this study only deterministic models with analytic solutions are involved, or parameters calculation by numeric methods, which the complete model can subsequently be treated as a theoretical model. Models deduction are summarised and presented a…

Postural changes in patients undergoing hyoid surgery for OSAS

2017

The hyoid bone is the only â suspended boneâ in our body, and its suspension system has an important role in posture maintenance. We studied postural modification in a group of patients affected by Obstructive Sleep Apnea Syndromewho had undergone surgical treatment including hyoid suspension. The surgical procedure performed was section of supra- and infrahyoid muscle and mobilization of the hyoid bone through its suspension to the thyroid cartilage. We studied the postural changes with stabilometric tests. In the early post-operative (one week) follow-up, we performed a posturography test with closed eyes and occlusal disjunction, and saw a worsening of the average parameter of the centre…

Psychomotor slowness is associated with self-reported sleep duration among the general population

2010

Short and long self‐reported sleep durations have been found to be associated with several seemingly disparate health risks and impaired functional abilities, including cognitive functioning. The role of long sleep is especially poorly understood in this context. Psychomotor slowness, shown to have analogous associations with cognitive performance and health risks as self‐reported long sleep duration, has not been studied together with sleep duration in epidemiological settings. We hypothesized that self‐reported habitual sleep duration, especially long sleep, is associated with slow psychomotor reaction time, and that this association is independent of vigilance‐related factors. The hypoth…
