The purpose of this study was to determine if a genetic counseling student's perception of the supervisory working alliance (SWA) is related to their self-efficacy on select clinical practice-based competencies (PBCs), evaluating the second tenet of the Reciprocal Engagement Model of Supervision (REM-S) from a student perspective. Second year genetic counseling students (N = 168) completed a survey containing demographic and clinical rotation experience questions, the Supervisory Working Alliance Inventory-Trainee Form (SWAI-T), and the Genetic Counseling Self-Efficacy Scale (GCSES)...

Emotional events are preferentially retained in episodic memory. This effect is commonly attributed to enhanced consolidation and has been linked specifically to rapid eye movement (REM) sleep physiology. While several studies have demonstrated an enhancing effect of REM sleep on emotional item memory, it has not been thoroughly explored whether this effect extends to the retention of associative memory. Moreover, it is unclear how non-rapid eye movement (NREM) sleep contributes to these effects. The present study thus examined associative recognition of emotional and non-emotional material across an early morning nap (N= 23) and sustained wakefulness (N= 23)...

Introduction: Rapid eye movement (REM) sleep-related bradyarrhythmia syndrome is characterized by pathological asystoles during the REM sleep phase. It is a rare rhythm disorder, being reported only few times in the literature. Due to non-specific symptoms, REM sleep-related bradyarrhythmia might be often underdiagnosed. Other cardiac diseases associated with pathological sinus arrests must be excluded to establish the correct diagnosis of and appropriate therapy for REM sleep-related bradyarrhythmia...

Biallelic GBA mutations cause Gaucher disease (GD), and heterozygous carriers are at risk for synucleinopathies. No founder GBA mutations in French-Canadians are known. GBA was fully sequenced using targeted next generation and Sanger sequencing in French-Canadian Parkinson disease (PD) patients (n=436), REM-sleep behavior disorder (RBD) patients (n=189) and controls (n=891). Haplotype, identity by descent (IBD) and principal component analyses (PCA) were performed using SNP-chip data. Data on GD patients from Toronto and Montreal were collected from patients' files...

Rapid eye movement (REM) sleep has an essential role in the process of learning and memory in the hippocampus. It has been reported that linalool, a major component of Lavandula angustifolia , has antioxidant, anti-inflammatory, and neuroprotective effects, along with other effects. However, the effect of linalool on the cognitive impairment and behavioral alterations that are induced by REM-sleep deprivation has not yet been elucidated. Several studies have reported that REM-sleep deprivation-induced memory deficits provide a well-known model of behavioral alterations...

Background Sleep deprivation as well as peripheral neuropathy and cutaneous neurogenic inflammation has a facilitatory effect on pain perception. Here we studied whether oxidative stress-related mechanisms in the spinal cord that have been shown to contribute to pain facilitation in peripheral neuropathy and cutaneous neurogenic inflammation play a role in sleep deprivation-induced pain hypersensitivity Methods Flower pot method was used to induce rapid eye movement sleep deprivation (REMSD) of 48 h duration in the rat that had a chronic intrathecal (i...

Brain oscillations in the gamma frequency band of the electroencephalogram (EEG) have been implicated in several sensory and cognitive processes, and have also been associated with numerous neuropsychiatric disorders, including depression. The widely prescribed selective serotonin reuptake inhibitors (SSRIs), similarly to other antidepressants, are known to produce markedly different effects on sleep and behavioral measures with acute and chronic administration. Although there are studies examining the acute effect of escitalopram on slower (<30 Hz) oscillations, we hardly could find any data about the effect of the drug on higher-frequency EEG oscillations (>30 Hz) in different sleep-wake stages, particularly comparing the acute and chronic effects of the drug concerning gamma oscillations...

Serotonin (5-HT) neurons are involved in wake promotion and exert a strong inhibitory influence on rapid eye movement (REM) sleep. Such effects have been ascribed, at least in part to the action of 5-HT at post-synaptic 5-HT1A receptors (5-HT1A R) in the brainstem, a major wake/REM sleep regulatory center. However, the neuroanatomical substrate through which 5-HT1A R influence sleep remains elusive. We therefore investigated whether a brainstem structure containing a high density of 5-HT1A R mRNA, the GABAergic Gudden's dorsal tegmental nucleus (DTg), may contribute to 5-HT-mediated regulatory mechanisms of sleep-wake stages...

Stroke is a major cause of disability and death in the United States and across the world, and the incidence and prevalence of stroke are expected to rise significantly due to an aging population. Obstructive sleep apnea, an established independent risk factor for stroke, is a highly prevalent disease that is estimated to double the risk of stroke. It remains uncertain whether non-apnea sleep disorders increase the risk of stroke. Areas covered: This paper reviews the literature describing the association between incident stroke and sleep apnea, REM sleep behavior disorder, restless legs syndrome, periodic limb movements of sleep, insomnia, and shift work...

OBJECTIVE: To describe clinical and pathologic characteristics of diffuse Lewy body disease (DLBD) manifesting as corticobasal syndrome (CBS). METHODS: In 523 autopsy-confirmed cases of DLBD, we identified 11 patients diagnosed with CBS. For comparison, we studied 22 DLBD brains with antemortem presentation of dementia with Lewy bodies (DLB). Given previous studies suggesting the importance of pathology in peri-Rolandic cortices in CBS, we used digital pathology to count Lewy bodies and to quantify intracytoplasmic and neuritic α-synuclein and phospho-tau burden in the motor cortex...

BACKGROUND: Chikungunya virus (CHIKV) is an emerging arboviral infection with a global distribution and may cause fetal and neonatal infections after maternal CHIKV-infections during gestation. METHODOLOGY: We performed a systematic review to evaluate the risk for: a) mother-to-child transmission (MTCT), b) antepartum fetal deaths (APFD), c) symptomatic neonatal disease, and d) neonatal deaths from maternal CHIKV-infections during gestation. We also recorded the neonatal clinical manifestations after such maternal infections (qualitative data synthesis)...

Patients with movement disorders have a high prevalence of sleep disturbances that can be classified as (1) nocturnal sleep symptoms, such as insomnia, nocturia, restless legs syndrome (RLS), periodic limb movements (PLM), obstructive sleep apnea (OSA), and REM sleep behavior disorder; and (2) diurnal problems that include excessive daytime sleepiness (EDS) and sleep attacks. The objective of this review is to provide a practical overview of the most relevant scales that assess these disturbances to guide the choice of the most useful instrument/s depending on the line of research or clinical focus...

Repeated corticosterone (CORT) injections reliably produce depressive-like behavior in rodents. Our previous study showed that sleep parameters were altered in rats after daily injections of CORT for 7 days, and sleep disturbances appeared to be correlated with depressive-like behavior. The aim of the present study was to investigate time-dependent correlations between changes in sleep parameters and the formation of depressive-like behavior in rats after more prolonged treatment with CORT. Rats received daily injections of CORT (40 mg/kg, s...

Mammalian sleep comprises the stages of slow-wave sleep (SWS) and rapid eye movement (REM) sleep. Additionally, a transition state is often discriminated which in rodents is termed intermediate stage (IS). Although these sleep stages are thought of as unitary phenomena affecting the whole brain in a congruent fashion, recent findings have suggested that sleep stages can also appear locally restricted to specific networks and regions. Here, we compared in rats sleep stages and their transitions between neocortex and hippocampus...

BACKGROUND: Obesity and anthropometric measurements predict more severe sleep-disordered breathing (SDB) in children, and are associated with cardiovascular risk factors in children without SDB. We aimed to investigate whether anthropometric measurements predicted autonomic control in children with SDB. We hypothesised that anthropometric measures would be significant predictors of decreased heart rate variability. METHODS: Children (3-17 years) with SDB (n = 298) and non-snoring controls (n = 126) underwent polysomnography...

Some shiftwokers in the long-haul transportation industries (i.e. road, rail, sea, air) have the opportunity to sleep in on-board rest facilities during duty periods. These rest facilities are typically fitted with a seat with a maximum back angle to the vertical of 20°, 40°, or 90°. The aim of this study was to examine the impact of "back angle" on the quantity and quality of sleep obtained in a seat during a daytime nap. Six healthy adults (3 females aged 27.0 years and 3 males aged 22.7 years) each participated in three conditions...
