Obstructive sleep apnoea independently predicts lipid levels: Data from the European Sleep Apnea Database
2018
Background and objective: Obstructive sleep apnoea (OSA) and dyslipidaemia are independent risk factors for cardiovascular disease. This study investigates the association between OSA and plasma lipid concentrations in patients enrolled in the European Sleep Apnea Database (ESADA) cohort. Methods: The cross-sectional analysis included 8592 patients without physician-diagnosed hyperlipidaemia or reported intake of a lipid-lowering drug (age 50.1 ± 12.7 years, 69.1% male, BMI: 30.8 ± 6.6 kg/m2, mean apnoea–hypopnoea index (AHI): 25.7 ± 25.9 events/h). The independent relationship between measures of OSA (AHI, oxygen desaturation index (ODI), mean and lowest oxygen saturation) and lipid profil…

Association of lifestyle factors and neuropsychological development of 4-year-old children
2020
Background: We aimed to assess how lifestyle factors such as diet, sleep, screen viewing, and physical activity, individually, as well as in a combined score, were associated with neuropsychological development in pre-school age children. Methods: We conducted a cross-sectional study in 1650 children of 4 years of age, from the Environment and Childhood Project (INMA) population-based birth cohorts in four regions of Spain. Children were classified per a childhood healthy lifestyle score (CHLS) with a range of 0 to 4 that included eating in concordance with the Mediterranean diet (1 point)
Leisure-time physical activity, sedentary behaviors, sleep, and cardiometabolic risk factors at baseline in the PREDIMED-PLUS intervention trial: A c…
2017
Limited data exists on the interrelationships between physical activity (PA), sedentary behaviors and sleep concerning cardiometabolic risk factors in aged adults at high cardiovascular disease risk. Our aim was to examine independent and joint associations between time spent in leisure-time PA, sedentary behaviors and sleep on the prevalence of obesity, type 2 diabetes (T2D) and components of the metabolic syndrome (MetS) in Mediterranean individuals at high cardiovascular risk. Cross-sectional analyses were performed on baseline data from 5776 Spanish adults (aged 55-75y in men; 60-75y in women) with overweight/ obesity and MetS, from October 2013 to October 2016, in the PREDIMED-PLUS tri…
Isotemporal substitution of inactive time with physical activity and time in bed: cross-sectional associations with cardiometabolic health in the PRE…
2019
Background: This study explored the association between inactive time and measures of adiposity, clinical parameters, obesity, type 2 diabetes and metabolic syndrome components. It further examined the impact of reallocating inactive time to time in bed, light physical activity (LPA) or moderate-to-vigorous physical activity (MVPA) on cardio-metabolic risk factors, including measures of adiposity and body composition, biochemical parameters and blood pressure in older adults. Methods: This is a cross-sectional analysis of baseline data from 2189 Caucasian men and women (age 55-75 years, BMI 27-40 Kg/m(2)) from the PREDIMED-Plus study (http://www.predimedplus.com/). All participants had >= 3…
Evaluation of nocturnal vs. morning measures of heart rate indices in young athletes
2022
Purpose The purpose of this study was to compare heart rate (HR) and heart rate variability in young endurance athletes during nocturnal sleep and in the morning; and to assess whether changes in these values are associated with changes in submaximal running (SRT) and counter-movement jump (CMJ) performance. Methods During a three-week period of similar training, eleven athletes (16 ± 1 years) determined daily HR and heart rate variability (RMSSD) during sleep utilizing a ballistocardiographic device (Emfit QS), as well as in the morning with a HR monitor (Polar V800). Aerobic fitness and power production were assessed employing SRT and CMJ test. Results Comparison of the average values fo…
Effects of mandibular setback surgery on upper airway dimensions and their influence on obstructive sleep apnoea - a systematic review.
2015
Abstract Background Mandibular setback used to be the traditional treatment of choice for correcting mandibular prognathism. Nowadays, bimaxillary surgery is preferred. Several authors have asserted that mandibular setback causes a relative narrowing of the upper airway (UA) that could trigger obstructive sleep apnoea (OSA); however, its potential role in OSA development is still much debated. Another controversial subject is whether changes in airway space caused by the procedure are permanent. Objectives To ascertain the consequences for UA size and shape of mandibular setback surgery in comparison with bimaxillary surgery (maxillary advancement with Le Fort I and mandibular setback), and…
The dark side of social media: Stalking, online self‐disclosure and problematic sleep
2021
The proliferation of social media usage has led to the manifestation of certain negative behaviours that are now referred to as the ‘dark side’ of social media use. These behaviours are a matter of concern, as they are detrimental to people's well-being. The present study examines the empirical association among social media stalking, online self-disclosure, social media sleep hygiene, compulsive social media use and problematic sleep, most of which have been previously recognized as key dark side behaviours. While social media stalking is a relatively new and under-explored phenomenon, its predecessor, the much-castigated cyberstalking, has received sufficient scholarly attention. This stu…

One of the most critical aspect for a wide use of neural networks to real world problems is related to the learning process which is known to be computational expensive and time consuming.
Perioperative Adverse Events in Obstructive Sleep Apnea and Use of Noninvasive Mechanical Ventilation: Key Topics and Clinical Implications
2016
Obstructive sleep apnea (OSA) is a common public health care problem and, yet, the perioperative management of OSA remains inadequate. Patients affected by this condition are prone to early postoperative complications, in part due to the negative effects of sedative, analgesic, and anesthetic agents on pharyngeal tone and arousal responses to hypoxia, hypercapnia, and obstruction. The use of opioids may also contribute to late adverse events, mainly by suppressing the rapid eye movement phase of sleep. As a result, preoperative screening of patients at high risk of OSA, as well as the implementation of a perioperative strategy to reduce the risk of complications, should lead to early periop…
