The US National Library of Medicine and National Institutes of Health manage PubMed.gov which comprises of more than 29 million records, papers, reports for biomedical literature, including MEDLINE, life science and medical journals, articles, reviews, reports and books.
BioPortfolio aims to cross reference relevant information on published papers, clinical trials and news associated with selected topics - speciality.
For example view all recent relevant publications on Epigenetics and associated publications and clincial trials.
Obstructive sleep apnea (OSA) has many effects on subjective parameters of the disease, such as reduction in quality of life (QoL), sleep quality (SQ), and increases in daytime sleepiness. Studies have reported the beneficial effect of exercise training on OSA severity; however, whether it improves subjective parameters remains unclear. The purpose of the present review was to investigate the effect of exercise training on QoL, daytime sleepiness, and SQ in adults with OSA by summarizing the results of clin...
Restless legs syndrome (RLS) is a common neurological disorder but it is not sufficiently recognized in children and adolescents. It often overlaps with growing pains in children, and as a result the clinical characteristics of pediatric RLS are not well studied, especially in Asia. The purpose of this study is to investigate the clinical characteristics of pediatric RLS patients in Korea and compare it to those of adult RLS patients.
While positive airway pressure (PAP) is effective for treating sleep-disordered breathing (SDB) in children, adherence is poor. Studies evaluating predictors of PAP adherence have inconsistent findings, and no rigorous reviews have been conducted. This systematic review aims to summarize the literature on predictors of PAP therapy adherence in children.
Brain iron deposition in hemodialysis (HD) patients increases over time. Iron deficiency in gray matter nuclei has been reported to lead to idiopathic restless legs syndrome (RLS) symptoms. Regardless of unpleasant RLS sensations, the patterns of iron deposition between hemodialysis patients with RLS (HD-RLS) and hemodialysis patients without RLS (HD-nRLS) are still unclear. To evaluate the differences in iron deposition patterns between HD-RLS and HD-nRLS patients, we utilized quantitative susceptibility m...
To assess the effectiveness and safety of Zao Ren An Shen (ZRAS), a Chinese herbal medicine formula, for the treatment of insomnia.
To develop an algorithm for improving apnea hypopnea index (AHI) estimation which includes event by event validation and event duration estimation. The algorithm uses breathing sounds, respiratory related movements and blood oxygen saturation (SaO).
We determined the relationships among the subjective symptoms of sleep apnea and daytime sleepiness, depressive symptoms, and anxiety in adults with obstructive sleep apnea (OSA).
To investigate the validity of the Brief Infant Sleep Questionnaire (BISQ), in assessing sleep quality in childhood.
To analyze the association between sleep-related symptoms and sleep length in parents and their children in relation to other risk factors in both generations.
This population-based study aimed to determine the effects of sleep deprivation and compensatory weekend catch-up sleep on the risk of falls in adolescents.
Sleep-disordered breathing (SDB) in children is common. Interest in sleep tests, such as polygraphy (PG), which can be performed in a non-attended setting, are gaining is increasing. PG has, however, been little studied in children with co-morbidities other than obstructive sleep apnea (OSA), and in particular, if performed in a non-attended setting. We report on the feasibility and interpretability of implementing PGs at home versus in hospital.
Previous studies comparing objective sleep measures between patients with Parkinson's disease (PD) and control participants were limited by their small sample size. The purpose of this study was to compare objective sleep measures between large-scale cohorts of PD outpatients and community-based older adults.
Fibrinogen is believed to play a role in the pathophysiology of obstructive sleep apnea (OSA) and many studies have assessed circulating fibrinogen concentrations in OSA patients. However, the results from these studies were not consistent. To assess the association of circulating fibrinogen levels and OSA, a meta-analysis was performed.
Sleep disordered breathing (SDB) causes sleep disturbance and daytime symptoms in children with neuromuscular disorders. Although polysomnography (PSG) findings are well described in many neuromuscular disorders, there are limited reports from children with spinal muscular atrophy (SMA). The aim of this study was to determine the sleep architecture and breathing characteristics and non-invasive ventilation (NIV) use in our pediatric SMA cohort.
The coexistence of sleep-related breathing disorders (SRBD) and sleep bruxism (SB) is often mentioned in the literature. Polysomnography (PSG) with video recording gives the best opportunity to identify both of these phenomena. This study aimed to evaluate the relationship between SRBD and SB.
Narcolepsy is a chronic, debilitating neurological disorder of sleep-wake state instability. This instability underlies all narcolepsy symptoms, including excessive daytime sleepiness (EDS), symptoms of rapid eye movement (REM) sleep dysregulation (ie, cataplexy, hypnagogic/hypnopompic hallucinations, sleep paralysis), and disrupted nighttime sleep. Several neurotransmitter systems promote wakefulness, and various neural pathways are involved in regulating REM sleep-related muscle atonia, providing multiple...
Currently, little is known regarding whether changes in physical activity are associated with changes in sleep in general population. The aim of this study was to examine the association between changes in physical activity and changes in sleep duration and difficulties at retirement transition point.
Prior evidence suggests that sleep duration and sleep difficulties may be associated with cognitive function in old age, but little is known about the sleep-cognition association in late mid-life. Our aim was to examine the associations of accelerometer-based sleep duration as well as subjective sleep difficulties with different domains of cognitive function among aging workers.
To determine if nigrostriatal dopaminergic system function, evaluated by aromatic l-amino acid decarboxylase (AADC) activity using 6-[F]fluoro-meta-tyrosine brain positron emission tomography (FMT-PET) can accurately and efficiently identify idiopathic rapid-eye-movement behavior disorder (IRBD) individuals at risk for conversion to a clinical diagnosis of Parkinson's disease (PD) or dementia with Lewy bodies (DLB).
Sleep bruxism, a major sleep disorder that causes serious harm to oral health, is considered a multifactorial disease. Sleep bruxism can be induced by smoking, which also adversely affects sleep quality. The objective of present study was to clarify the associations between sleep bruxism, sleep quality, and exposure to secondhand smoke (SHS).
The association between self-reported sleep dissatisfaction after the Great East Japan Earthquake, and a deteriorated socioeconomic status in the evacuation area: the Fukushima Health Management Survey.
Currently, few studies have thoroughly investigated the socioeconomic factors related to sleep problems among evacuees following a disaster.
Evidence on sex differences in the association between obstructive sleep apnea (OSA) and cardiovascular outcomes is limited and controversial. We conducted a historical cohort study to investigate this relationship.
