A systematic literature review and meta-analyses (where appropriate) were performed the GRADE approach was used to update previous American Academy of Sleep Medicine Practice Parameters on treatment intrinsic circadian rhythm sleep-wake disorders.Available data allowed for positive endorsement (at a second-tier degree confi dence) strategically timed melatonin (for DSWPD, blind adults with N24SWD, children/ adolescents ISWRD comorbid neurological disorders), light therapy or without...

Long and short sleep duration are associated with increased risk for coronary heart disease (CHD) cardiovascular (CVD); however, evidence is inconsistent. We sought to identify whether self-reported insomnia, based on a validated questionnaire, incident CHD CVD among postmenopausal women. Women's Health Initiative Observational Study Participants (N=86,329; 50-79 years) who reported at baseline were followed events. Associations of insomnia evaluated using Cox proportional hazards models...

BackgroundThere is no consensus on reporting light characteristics in studies investigating non-visual responses to light. This project aimed develop a checklist for laboratory-based investigations the impact of physiology.MethodsA four-step modified Delphi process (three questionnaire-based feedback rounds and one face-to-face group discussion) involving international experts was conducted reach items be included checklist. Following process, resulting tested pilot phase with independent...

Disturbed sleep and on‐the‐job sleepiness are widespread problems among night shift workers. The pineal hormone melatonin may prove to be a useful treatment because it has both sleep‐promoting circadian phase‐shifting effects. This study was designed isolate melatonin’s effects, determine whether could improve daytime thus time alertness performance during the shift. utilized placebo‐controlled, double‐blind, cross‐over design. Subjects ( n =21, mean age=27.0 ± 5.0 years) participated in two...

There has been scant evidence for a phase-shifting effect of melatonin in shift-work or jet-lag protocols. This study tested whether can facilitate phase shifts simulated night-work protocol. Subjects ( n = 32) slept the afternoons/evenings before night work (a 7-h advance sleep schedule). They took (0.5 mg 3.0 mg) placebo first four eight afternoon/evening episodes at time when shown to circadian clock. Melatonin produced larger advances than rhythms and temperature. Average (±SD) dim light...

Background Universal screening for postpartum depression is recommended in many countries. Knowledge of whether the disclosure depressive symptoms period differs across cultures could improve detection and provide new insights into pathogenesis. Moreover, it a necessary step to evaluate universal use instruments research clinical practice. In current study we sought assess Edinburgh Postnatal Depression Scale (EPDS), most widely used tool depression, measures same underlying construct...

Background: Gender-related differences have been found among invited speakers in select professional and medical societies. We examined whether similar disparities existed keynote speakers, plenary lecturers a broad range of specialty conferences from 2013 to 2017. Materials Methods: A cross-sectional study was performed on 27 U.S. for which data were available and/or lecturers. For each speaker, gender degree(s) determined. Fisher's exact test compare proportions women Association American...

Abstract Later sleep timing, circadian preference, and rhythm timing predict worse outcomes across multiple domains, including mood disorders, substance use, impulse control, cognitive function. Disturbed is common among pregnant postpartum women. We examined whether during third trimester of pregnancy predicted symptoms mania, depression, obsessive-compulsive disorder (OCD). Fifty-one women with a previous, but not active, episode unipolar or bipolar depression had evaluated recorded wrist...

Sex differences in circadian rhythms have been reported with some conflicting results. The timing of sleep and length time bed not considered, however, previous such studies. current study has 3 major aims: (1) replicate studies a large sample young adults for sex patterns dim light melatonin onset (DLMO) phase; (2) subsample constrained by matching across bedtime bed, confirm DLMO phase angle to bedtime; (3) explore the influence on angle. A total 356 first-year Brown University students...

Despite the omnipresence of artificial and natural light exposure, there exists little guidance in United States elsewhere on exposure terms timing, intensity, spectrum, other characteristics known to affect human health, performance, well-being; parallel, is information regarding quantity that people receive. To address this, National Center Sleep Disorders Research, Division Lung Diseases, Heart, Lung, Blood Institute, held a workshop August 2016 circadian health light. Workshop...
