Physical Activity, Screen Time and Sleep among Youth Participating and Non-Participating in Organized Sports : The Finnish Health Promoting Sports Cl…

2016

Objectives: The aim of this Health Promoting Sport Club (HPSC) study was to compare physical activity (PA), sleep time and screen time (ST) between sports club participants (n = 1200) and non-participants (n = 913). Design: A cross-sectional survey design was employed to assess PA, sleep and ST of adolescents. Methods: Information on these was collected from 14 to 16 year old adolescents (1200 sport club participants and 913 non-participants) through a standardized questionnaire. Results: Boys were more physically active than girls and met the PA guidelines more often than girls (p < 0.001). The proportion of youth reaching the PA guidelines was significantly higher among youth participants…

Granger causality analysis of sleep brain-heart interactions

2014

We studied the networks of Granger causality (GC) between the time series of cardiac vagal autonomic activity and brain wave activities, measured respectively as the normalized high frequency (HF) component of heart rate variability and EEG power in the δ, θ, α, σ, β bands, computed in 10 healthy subjects during sleep. GC analysis was performed by vector autoregressive modeling, and significance of each link in the network was assessed using F-statistics. The whole-night analysis revealed the existence of a fully connected network of brain-heart and brain-brain interactions, with the ß EEG power acting as a hub which conveys the largest number of GC links between the heart and brain n…

Adolescent use of social media and associations with sleep patterns across 18 European and North American countries

2023

Objective Over the past decade, concurrent with increasing social media use (SMU), there has been a shift toward poorer sleep among adolescents in many countries. The purpose of this study was to examine the cross-national associations between adolescent SMU and sleep patterns, by comparing 4 different categories of SMU (nonactive, active, intense, and problematic use). Design, setting, and participants Data were from 86,542 adolescents in 18 European and North American countries that participated in the 2017/18 Health Behaviour in School-aged study. Measurements Mixed-effects linear regression models were used to examine cross-national associations between 4 SMU categories and adolescent s…

Neuroplasticity and environment: A pharmacotherapeutic approach toward preclinical and clinical understanding

2021

International audience; Emerging research in the field of behavioral neuroscience has demonstrated the fundamental role of the cerebral organization. For brain development, various important functions are required for instance synaptic plasticity and neurogenesis. This property is described in terms of neuroplasticity. Neuroplasticity denotes the extraordinary ability of the brain for the recognition of its structure and function after an experience with some external stimuli and involves in the various behavioral processes of the brain such as cognitive functions. It has multiple factors that can range from gene alteration to environmental factors. Environmental factors exert both negative…

Cognitive and Physical Activity-Related Aspects of Children Associated to the Performance of the Crunning Movement

2021

The aim of this investigation was to identify possible related factors associated to the performance of the crunning test in European children and adolescents. A total number of 559 children and adolescents (age range 6&ndash

T helper 1 response is correlated with widespread pain, fatigue, sleeping disorders and the quality of life in patients with fibromyalgia and is modu…

2019

Hyperbaric oxygen therapy (HBOT) has been used as treatment for different clinical conditions, including fibromyalgia (FM). HBOT modulates brain activity, ameliorates chronic pain and modifies the ratio of immune cells. Clinical studies have provided evidence that FM is associated with immune system dysregulation. In the present study we aimed to evaluate the effect of HBOT on immune system and on the quality of life-style of FM patients.Patients with primary FM and controls were treated with HBOT. Physical, emotional and social assessment, quality of sleep, tender points, intensity score, WPI and symptom severity were evaluated before and after HBOT. Furthermore, a characterisation of CD4 …

Misdiagnosis and pitfalls in Panayiotopoulos syndrome

2019

Abstract Panayiotopoulos syndrome (PS) is a frequent (6% among children of 1–15 years) and benign epileptic syndrome, characterized by predominantly autonomic symptoms (emesis, pallor, flushing, cyanosis, mydriasis/miosis, cardiorespiratory and thermoregulatory alterations, incontinence of urine and/or feces, hypersalivation, and modifications of intestinal motility) associated with simple motor focal seizures, which can be followed by secondary generalization. Panayiotopoulos syndrome can be extremely insidious, because it can mimic several condition, such as gastroenteritis, gastroesophageal reflux disease, encephalitis, syncope, migraine, sleep disorders, or even metabolic diseases. This…

The role of reactive oxygen species in obesity therapeutics.

2019

Obesity is a major risk factor for multiple severe health conditions, including cardiovascular diseases, diabetes and cancer. It is often related to an increased risk of morbidity and mortality and, as it can be accompanied by non-fatal health problems, quality of life is seriously reduced due to related conditions including hypertension, sleep apnea, osteoarthritis, respiratory problems and infertility. Evidence suggests that oxidative stress is related to obesity and its complications. In obese patients, there is an increase in levels of reactive oxygen species and nitrogen species and antioxidant defenses are undermined in comparison to normal-weight counterparts. In addition, these para…

Information Transfer Between Respiration and Heart Rate During Sleep Apnea

2016

It is well-known that sleep apnea affects the respiration and the heart rate (HR), and studies have shown that the cardiorespiratory coupling is also compromised during obstructive sleep apnea (OSA). Furthermore, the classification of hypopneas is challenging, in particular when only ECG-derived features are used. In this context, this study investigates how different ECG-derived respiratory (EDR) signals resemble the respiratory effort during different types of apneas, and how the amount of information transferred from respiration to HR varies according to the respiratory signal used, real or ECG-derived. ECG and respiratory signals of 10 patients suffering from sleep apnea were analysed, …
