Sleep Duration and Risk of Fatal Coronary Heart Disease, Sudden Cardiac Death, Cancer Death, and All-Cause Mortality

2018

Background: Sleep duration has been shown to be associated with all-cause mortality, however its relationship with cause-specific fatal events remains uncertain. We examined the relationship between sleep duration and risk of fatal coronary heart disease (CHD), sudden cardiac death, cancer related death and all-cause mortality. Methods Sleep duration was self-reported at baseline examinations performed between March 20, 1984 and December 5, 1989 in 2,361 men aged 42-61 years old from the Kuopio Ischemic Heart Disease study. Of these 1734 (73.4%) men were free from CHD and cancer at baseline. Results: A total of 802 all cause deaths, 202 fatal coronary heart disease events, 141 sudden cardia…

Hyperuricemia and non-dipping blood pressure

2013

Oreste Marrone,1 Maria Rosaria Bonsignore1,21National Research Council, Institute of Biomedicine and Molecular Immunology, Palermo, Italy; 2Biomedical Department of Internal and Specialistic Medicine, University of Palermo, Palermo, ItalyThe strong association between the metabolic derangements that characterize the metabolic syndrome with arterial hypertension is very well-known, as it is the common finding of hyperuricemia in the patients with the metabolic syndrome. Besides, hyperuricemia has been found to be associated with cardiovascular, renal, and metabolic diseases; including not only gout but also type 2 diabetes mellitus, although its role as a risk factor is still debated.1 We we…

Volitional components of consciousness vary across wakefulness, dreaming and lucid dreaming

2014

Contains fulltext : 136156.pdf (Publisher’s version ) (Open Access) Consciousness is a multifaceted concept; its different aspects vary across species, vigilance states, or health conditions. While basal aspects of consciousness like perceptions and emotions are present in many states and species, higher-order aspects like reflective or volitional capabilities seem to be most pronounced in awake humans. Here we assess the experience of volition across different states of consciousness: 10 frequent lucid dreamers rated different aspects of volition according to the Volitional Components Questionnaire for phases of normal dreaming, lucid dreaming, and wakefulness. Overall, experienced volitio…

ASSOCIATION BETWEEN OBSTRUCTIVE APNEA SYNDROME DURING SLEEP AND DAMAGES TO ANTERIOR LABYRINTH: OUR EXPERIENCE.

2019

The obstructive sleep apnea syndrome is a chronic condition characterized by frequent episodes of collapse of the upper airways during sleep. It can be considered a multisystem disease. Among the districts involved, even the auditory system was seen to be concerned. It was enrolled a population of 20 patients after polysomnographic diagnosis of OSAS (Apnea Hypopnea Index > 10) and a control group of 28 healthy persons (Apnea Hypopnea Index < 5). Each patient has been subjected to Pure Tone Audiometry, Tympanometry, study of Acoustic Reflex, Otoacoustic Emissions and Auditory Brainstem Response. Moreover they were submitted to endoscopy of upper airway with Muller Maneuver and Epworth Sleepi…

Effects of exercise and dietary interventions on serum metabolites in men with insomnia symptoms: A 6-month randomized controlled trial

2020

Abstract Accumulating evidence show that exercise and diet interventions are associated with improved sleep quality. Studies investigating the effects of exercise and dieting on circulating metabolomics in people with sleep disorders, particularly insomnia, are scarce. This 6-month randomized study aimed to assess the effects of exercise and dietary interventions on serum metabolites in men with insomnia symptoms. Seventy-two Finnish men (age: 51.6 ± 10.1 years) with chronic insomnia symptoms who were assigned to different intervention groups completed this study (exercise, n = 24; diet, n = 27; and control, n = 21). The Shapiro-Wilk W-test, Levene test, Spearman correlation analysis, and a…

Relationship between sleep quality and postural balance in community-dwelling older persons: A cross-sectional study

2019

Objetivo Determinar la relación entre la calidad del sueño y el equilibrio postural en las personas mayores que viven en la comunidad. Métodos Se aplicó un estudio analítico y transversal. Se reclutaron 53 sujetos que cumplían los criterios de selección. Se aplicó el índice de calidad del sueño de Pittsburgh (PSQI) y se realizó una prueba de equilibrio estático a través de una posturografía computarizada para evaluar el equilibrio postural. Resultados Cincuenta y tres sujetos entre 60 y 80 años (M = 70,13; desviación estándar: 6,06) fueron evaluados; 69,8% correspondían a mujeres y 30,2% a hombres. La prueba de correlación encontró una relación estadísticamente significativa y positiva, per…

What Are We Measuring When We Evaluate Digital Interventions for Improving Lifestyle? A Scoping Meta-Review

2022

Background: Lifestyle Medicine (LM) aims to address six main behavioral domains: diet/nutrition, substance use (SU), physical activity (PA), social relationships, stress management, and sleep. Digital Health Interventions (DHIs) have been used to improve these domains. However, there is no consensus on how to measure lifestyle and its intermediate outcomes aside from measuring each behavior separately. We aimed to describe (1) the most frequent lifestyle domains addressed by DHIs, (2) the most frequent outcomes used to measure lifestyle changes, and (3) the most frequent DHI delivery methods.Methods: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA-…

Noninvasive Ventilation in Critically Ill Patients

2015

Since its first application in the late 1980s, noninvasive ventilation (NIV) has been the first-line intervention for certain forms of acute respiratory failure. NIV may be delivered through the patient's mouth, nose, or both using noninvasive intermittent positive pressure ventilation or continuous positive airway pressure. When applied appropriately, NIV may reduce morbidity and mortality and may avert iatrogenic complications and infections associated with invasive mechanical ventilation. This article provides physicians and respiratory therapists with a comprehensive, practical guideline for using NIV in critical care. © 2015 Elsevier Inc.

Convolutional Neural Network Based Sleep Stage Classification with Class Imbalance

2022

Accurate sleep stage classification is vital to assess sleep quality and diagnose sleep disorders. Numerous deep learning based models have been designed for accomplishing this labor automatically. However, the class imbalance problem existing in polysomnography (PSG) datasets has been barely investigated in previous studies, which is one of the most challenging obstacles for the real-world sleep staging application. To address this issue, this paper proposes novel methods with signal-driven and image-driven ways of noise addition to balance the imbalanced relationship in the training dataset samples. We evaluate the effectiveness of the proposed methods which are integrated into a convolut…
