Parasomnias in Post-Secondary Students: Prevalence, Distress, and Coping Strategies.

Parasomnias are a group of sleep disorders characterized by abnormal and unpleasant motor, verbal, or behavioral events that occur during sleep or during transitions between wake and sleep states. They disrupt sleep and can have a detrimental impact on the individual experiencing them. Our goal was to identify types of parasomnias and their prevalence in the current and recent post-secondary student population and to explore their coping strategies for parasomnias they found distressing.

Alternative splicing decouples local from global PRC2 activity.

The Polycomb repressive complex 2 (PRC2) mediates epigenetic maintenance of gene silencing in eukaryotes via methylation of histone H3 at lysine 27 (H3K27). Accessory factors define two distinct subtypes, PRC2.1 and PRC2.

Sleep and Well-Being during the COVID-19 Remote and In-Person Periods: Experiences of College Faculty and Staff with and without Disabilities.

We explored the impacts of the remote and return-to-in-person work periods on sleep and well-being as reported by faculty ( = 22) and non-teaching staff ( = 21) with and without disabilities. Participants were recruited through college platforms and personal contacts. Our results show that contrary to expectations, the COVID-19 remote teaching/working period resulted in better sleep, as well as greater well-being, than the return-to-in-person work period.

Impact of the COVID-19 pandemic on obstructive sleep apnea: recommendations for symptom management.

Study Objectives: In the context of the current COVID-19 pandemic situation, we address the following important questions: (1) How can patients be identified for possible OSA while sleep clinic testing is temporarily unavailable or limited? and (2) What measures can be suggested to improve sleep health until proper diagnosis and treatment become safe and available again?

Methods: As a proxy for home or in-laboratory testing, validation of a symptom-based measure of OSA risk is presented, based on an ongoing larger prospective study of 156 family medicine patients with OSA (88 women, 68 men; mean age, 57 years) and 60 control participants (36 women, 24 men; mean age, 54 years) recruited from the community. Participants completed the Sleep Symptom Checklist (SSC) and a range of other self-report measures; primary care patients also underwent a polysomnographic sleep study.

Results: Results showed that (1) individuals with OSA reported more symptoms on the SSC related to insomnia, daytime symptoms, sleep disorders, and psychological maladjustment than did the control group (all P < .

Disordered sleep is related to delusional ideation and depression during the perinatal period.

Objectives: This study investigates the associations between sleep disturbances, delusional ideation (DI), and depressive symptomatology across the perinatal period.

Methods: A community sample of 316 mothers completed the Sleep Symptom Checklist, Peters Delusional Inventory, and Edinburgh Postnatal Depression Scale at three time points: second trimester of pregnancy (12-14 weeks gestation), third trimester (32-34 weeks gestation), and two months postpartum.

Results: Longitudinal path analysis revealed a bidirectional relationship between sleep disturbance and DI across pregnancy.

Sleep quality is associated with vasopressin methylation in pregnant and postpartum women with a history of psychosocial stress.

Background: The relationship between disturbed sleep and stress is well-documented. Sleep disorders and stress are highly prevalent during the perinatal period, and both are known to contribute to a number of adverse maternal and foetal outcomes. Arginine vasopressin (AVP) is a hormone and a neuropeptide that is involved in stress response, social bonding and circadian regulation of the sleep-wake cycle.

Sleep in the Postpartum: Characteristics of First-Time, Healthy Mothers.

Goals for the present study were to (a) describe the sleep of healthy new mothers over a 6-month postpartum period, (b) examine how sleep quality relates to daytime levels of fatigue and sleepiness, and (c) evaluate the relationship between mothers' and infants' sleep parameters. The sample consisted of 37 healthy, partnered, first-time mothers who had experienced full-term vaginal birth and had a healthy infant. We investigated infants' sleep parameters and mothers' sleep, mood, and daytime functioning 2 and 6 months postpartum.

Determinants of policy decisions for non-commercial drivers with OSA: An integrative review.

Excessive daytime sleepiness and reduced cognitive functioning secondary to obstructive sleep apnea (OSA) have been identified as an important health-related risk in commercial transportation with, possibly, an increased chance of road accidents. This has resulted in a variety of policies and restrictions imposed on commercial drivers. Here we review current knowledge to assess whether available data are sufficient to guide policy decisions concerning restrictions for non-commercial drivers.

CPAP Treatment Adherence in Women with Obstructive Sleep Apnea.

Untreated obstructive sleep apnea (OSA) has numerous negative health-related consequences. Continuous positive airway pressure (CPAP) is generally considered the treatment of choice for OSA, but rates of nonadherence are high. It is believed that OSA is more prevalent among men; therefore understanding how OSA presents among women is limited and treatment adherence has received little research attention.

The challenge of identifying family medicine patients with obstructive sleep apnea: addressing the question of gender inequality.

Purpose: The purpose of this study was to examine the sleep characteristics, metabolic syndrome disease and likelihood of obstructive sleep apnea in a sample of older, family medicine patients previously unsuspected for sleep apnea.

Methods: A total of 295 participants, minimum age 45, 58.7% women, were recruited from two family medicine clinics.

Prevalence and Determinants of Insomnia After a Myocardial Infarction.

Objectives: This study analyzed cross-sectional data to examine the prevalence of insomnia and to identify factors associated with insomnia after a myocardial infarction (MI).

Methods: The participants were 209 individuals with a recent MI. At approximately 5 weeks post-MI, participants completed standardized self-report measures assessing insomnia (Insomnia Severity Index) and various sociodemographic, clinical, behavioral, and psychosocial variables, including stressful life events, depressive symptoms, and dysfunctional beliefs about sleep.

Refreshing Sleep and Sleep Continuity Determine Perceived Sleep Quality.

Sleep quality is a construct often measured, employed as an outcome criterion for therapeutic success, but never defined. In two studies we examined appraised good and poor sleep quality in three groups: a control group, individuals with obstructive sleep apnea, and those with insomnia disorder. In Study 1 we used qualitative methodology to examine good and poor sleep quality in 121 individuals.

Manifestations of Insomnia in Sleep Apnea: Implications for Screening and Treatment.

The aims of this study were to examine the presence, type, and severity of insomnia complaints in obstructive sleep apnea (OSA) patients and to assess the utility of the Sleep Symptom Checklist (SSC) for case identification in primary care. Participants were 88 OSA patients, 57 cognitive-behavioral therapy for insomnia (CBT-I) patients, and 14 healthy controls (Ctrl). Each completed a sleep questionnaire as well as the SSC, which includes insomnia, daytime functioning, psychological, and sleep disorder subscales.

Doxepin and cognitive behavioural therapy for insomnia in patients with Parkinson's disease -- a randomized study.

Introduction: Although a variety of pharmacologic and non-pharmacologic treatments are effective for insomnia in the general population, insomnia in Parkinson's disease differs in important ways and may need different treatments. No studies have conclusively demonstrated effective insomnia treatments in Parkinson's disease.

Methods: We conducted a three-arm six-week randomized pilot study assessing non-pharmacologic treatment (cognitive behavioural therapy with bright light therapy) or doxepin (10 mg daily), compared to an inactive placebo in Parkinson's patients with insomnia.

Do all individuals with sleep apnea suffer from daytime sleepiness? A preliminary investigation.

We derived descriptive characteristics related to habitual sleep duration and insomnia for individuals newly diagnosed with sleep apnea/hypopnea syndrome and evaluated how sleep apnea/hypopnea syndrome, insomnia, depression, and sleep duration relate to sleepiness and fatigue. In total, 100 participants were divided into three sleep groups: short (<7 hours), long (≥ 8 hours), and midrange (7-7.9 hours).

Release of serine/threonine-phosphorylated adaptors from signaling microclusters down-regulates T cell activation.

Antigen recognition within immunological synapses triggers and sustains T cell activation by nucleating protein microclusters that gather T cell receptors (TCRs), kinases, and adaptors. Dissipation of these microclusters results in signal termination, but how this process is regulated is unclear. In this paper, we reveal that release of the adaptors SLP76 and GADS from signaling microclusters is induced by the serine/threonine protein kinase HPK1 and that phosphorylation of GADS plays a major role in this process.

Fatigue: The forgotten symptom of sleep apnea.

Objective: The present investigation was designed to explore the role and implications of both daytime sleepiness and fatigue in obstructive sleep apnea syndrome with respect to sleep, perceived health quality, and psychological functioning.

Methods: Our participants consisted of two groups: 124 older community volunteers who completed a polysomnographic sleep study and were diagnosed with sleep apnea, and 19 healthy controls. All participants completed self-report measures of sleepiness, fatigue, sleep quality, health quality, and psychological functioning.

Classifying medication use in clinical research.

Background: Medication use data are usually collected in clinical research. Yet no standardized method for categorizing these exists, either for sample description or for the study of medication use as a variable.

Objective: The present investigation was designed to develop a simple, empirically based classification scheme for medication use categorization.

Impaired sleep in chronic fatigue syndrome: how is it best measured?

The goal was to examine comparative efficacy of polysomnography, actigraphy, and self-report in evaluating the sleep/wake experience of individuals with chronic fatigue syndrome (CFS). Sleep parameters were evaluated by the three measurement modalities for the same night in 49 participants with CFS. Psychological and daytime functioning were measured by self-report.

Sleep apnea and psychological functioning in chronic fatigue syndrome.

Objectives were to explore: (1) whether sleep apnea/hypopnea syndrome (SAHS) should be considered a chronic fatigue syndrome (CFS) comorbidity, rather than a diagnostic exclusion criterion; and (2) to compare sleep/wake/ psychopathology in individuals with CFS, controls and another illness. Participants (CFS, SAHS, controls) completed questionnaires and were evaluated for SAHS; 68 percent were subsequently diagnosed with SAHS. CFS participants with and without SAHS did not differ.

Sleep disorder symptoms are common and unspoken in Canadian general practice.

Objective: Primary care patients were surveyed for what sleep disorder symptoms they discussed with their physicians. Their responses were compared with those of new Sleep clinic patients. The goal was to discover what symptom presentation leads to a successful referral to a sleep clinic.

A diagnostic symptom profile for sleep disorder in primary care patients.

Objective: The aim of the present study was (1) to evaluate the extent and nature of sleep disorder-related symptoms in the older primary care patient population and (2) to differentiate a pattern of self-reported symptoms that identify patients who should be referred to the sleep clinic for further evaluation.

Method: One hundred ninety-six older adults recruited from family practice centers were administered a brief symptom survey measure. All were invited to participate in an extensive self-report evaluation, consultation with a sleep medicine specialist, and an overnight polysomnographic study.
