| The association of BDNF gene polymorphism with cognitive impairment in insomnia patients. | |
|
Abstract: BACKGROUND: Reductions in BDNF activity have shown associations with depressed mood. Other evidence has demonstrated that the BDNF Val66Met polymorphism (rs6265) appears to reduce neural plasticity. A limited number of studies have investigated the influence of these genetic polymorphisms in insomnia. The present study sought to confirm the presence of associations between BDNF Val66Met polymorphism (rs6265) occurrence in normal sleepers and those with insomnia...

| Psychometric properties of the severity of the dependence scale for Khat (SDS-Khat) in polysubstance users. | |
|
 |
Abstract: Background: Current evidence suggests that the addiction on one substance may underpin or affect addiction on another in polysubstance users. However, there is no tool that has been shown to have psychometric validation for assessment of the severity of khat addiction in polysubstance users...| Validation of the adapted Leeds sleep evaluation questionnaire in Ethiopian university students. | |
|
Abstract: Background: Current evidence supports the applicability of the Leeds Sleep Evaluation Questionnaire (LSEQ) in screening for insomnia. The psychometric properties of the LSEQ have never been investigated in an African population. Therefore, this study aimed to validate the adapted version of the LSEQ-Mizan (LSEQ-M) in Ethiopian university students...

| Kleine-Levin syndrome is associated with LMOD3 variants. | |
|
|
Abstract: Kleine‐Levin syndrome (KLS) is a rare periodic hypersomnia with associated behavioural abnormalities but with often favourable prognosis. There is excess risk of KLS in first‐degree relatives, suggesting a strong genetic contribution. So far, no mutation is identified in KLS and comprehensive genetic analysis of affected individuals is lacking. Here we performed whole genome single‐nucleotide polymorphism (SNP) genotyping and exome sequencing in a large family with seven affected members. The identified gene with a mutation was resequenced in 38 sporadic KLS patients and the expression of the gene product was mapped in the mouse brain...| Left ventricular diastolic dysfunction in patients with obesity hypoventilation syndrome. | |
|
Abstract: Background: Obesity hypoventilation syndrome (OHS) can be complicated by several cardiovascular conditions. We assessed the prevalence and factors associated with left ventricular diastolic dysfunction (LVDD) in patients with OHS. Methods: In this prospective observational study, all consecutive OHS patients referred to the sleep disorders clinic between January 2002 to December 2016 were included (n=113). Demographic data, echocardiography, sleep parameters, arterial blood gases (ABGs), and lung functions were recorded... |
| How does diurnal intermittent fasting impact sleep, daytime sleepiness, and markers of the biological clock? Current insights. | |
|
Abstract: Mealtimes and feeding schedules may interfere with the circadian system and impact sleep. The practice of intermittent fasting (IF) in its different formats is increasing worldwide. However, most studies addressing the effect of IF on circadian rhythms, daytime sleepiness, and sleep architecture have been conducted during diurnal IF for Ramadan...

| Intermittent Fasting, Insufficient Sleep, and Circadian Rhythm: Interaction and Effects on the Cardiometabolic System. | |
|
|
Abstract: Purpose of Review: Sleep, circadian rhythms, and fasting/feeding are important factors that affect cardiometabolic function. Here, we review recent studies that assessed the role of intermittent fasting, short sleep duration, and circadian rhythm disruption, as well as their interactions, on the risk of cardiometabolic dysfunction...| The effect of air conditioner sound on sleep latency, duration, and efficiency in young adults. | |
|
Abstract: BACKGROUND: Many individuals complain of disturbed sleep during the wintertime when their air conditioner (AC) is off. Therefore, we conducted this study to objectively assess the impact of AC sound on sleep latency, sleep duration, and sleep efficiency. METHODS: An experimental study was conducted on 48 healthy young adults, in their homes, to assess the effect of a standardized AC white noise, on sleep latency, duration, and efficiency, while simultaneously monitoring light intensity and room temperature. The study was conducted during the winter months. Sleep quality was objectively assessed using sleep actigraphy...
