Sleep apnea and kidney transplant outcomes: findings from a 20-year (1997-2017) historical cohort study.

Objective/background: A historic cohort single-center study of kidney transplant recipients with graft loss examined the associations between sleep apnea and two transplant outcomes, death with a functioning graft (DWFG), and graft survival time.

Patient/methods: Adult patients who received transplants and experienced graft failure or DWFG from January 1, 1997 to January 1, 2017 constituted the cohort (n = 322). Data for the study were obtained by merging two secondary data sources: the Organ Procurement and Transplantation Network (OPTN) database and the transplant center's medical records.

The deterioration of driving performance over time in drivers with untreated sleep apnea.

Sleep apnea increases risk of driving crashes when left untreated. This study examined the driving performance decrements of untreated, undiagnosed sleep apnea drivers compared with healthy controls in a monotonous highway driving simulator task. It was hypothesized that the sleep apnea group would perform worse during a driving simulator test compared with the control group.

National Sleep Foundation's updated sleep duration recommendations: final report.

Objective: To make scientifically sound and practical recommendations for daily sleep duration across the life span.

Methods: The National Sleep Foundation convened a multidisciplinary expert panel (Panel) with broad representation from leading stakeholder organizations. The Panel evaluated the latest scientific evidence and participated in a formal consensus and voting process.

National Sleep Foundation's sleep time duration recommendations: methodology and results summary.

Objective: The objective was to conduct a scientifically rigorous update to the National Sleep Foundation's sleep duration recommendations.

Methods: The National Sleep Foundation convened an 18-member multidisciplinary expert panel, representing 12 stakeholder organizations, to evaluate scientific literature concerning sleep duration recommendations. We determined expert recommendations for sufficient sleep durations across the lifespan using the RAND/UCLA Appropriateness Method.

Adolescent crash rates and school start times in two central Virginia counties, 2009-2011: a follow-up study to a southeastern Virginia study, 2007-2008.

Background And Objective: Early high school start times (EHSST) may lead to sleep loss in adolescents ("teens"), thus resulting in higher crash rates. (Vorona et al., 2011).

Hypnotic hiccups.

Our patient presented with repetitive, self-limited bouts of forceful hiccups in sleep. Eszopiclone, a commonly prescribed hypnotic, appeared to cause these intermittent hiccups. This case is a reminder that eszopiclone may cause this adverse effect, and that it may be the bed partner and not the patient who furnishes critical sleep medicine history.

Nocturnal diaphoresis secondary to mild obstructive sleep apnea in a patient with a history of two malignancies.

Numerous medical disorders, including obstructive sleep apnea, may cause nocturnal diaphoresis. Previous work has associated severe obstructive sleep apnea with nocturnal diaphoresis. This case report is of import as our patient with severe nocturnal diaphoresis manifested only mild sleep apnea, and, for years, his nocturnal diaphoresis was ascribed to other causes, i.

Dissimilar teen crash rates in two neighboring southeastern Virginia cities with different high school start times.

Study Objectives: Early high school start times may contribute to insufficient sleep leading to increased teen crash rate. Virginia Beach (VB) and Chesapeake are adjacent, demographically similar cities. VB high schools start 75-80 minutes earlier than Chesapeake's.

Effects of call on sleep and mood in internal medicine residents.

Residents on call experience decreased total sleep time (TST) and increased dysphoria. This study monitored changes in mood and sleepiness for 3 post-call days. Fifty-two internal medicine residents participated in the study.

A survey of subjective sleepiness and consequences in attending physicians.

This article surveyed attending physicians on their work hours, sleep schedule, daytime sleepiness, and the perceived relation of these factors to patient safety, quality of care, and personal well-being. Physicians answered demographic and workload questions and attitudinal questions regarding work-hour limitations; the Epworth Sleepiness Scale (ESS) was used to measure subjective sleepiness, and an 18-item Impact Questionnaire was also used. Of 180 participants, 41 (23%) attending physicians manifested abnormal ESS scores (11 or greater).

Treatment of severe obstructive sleep apnea syndrome with a chinstrap.

A chinstrap alone improved severe obstructive sleep apnea as well as or better than the use of CPAP.

Medical resident driving simulator performance following a night on call.

This study compared driving simulation performance after night call and after being off call in 22 medical residents and 1 medical student in a prospective within-subjects counterbalanced design. The results demonstrated an unexpected interaction between call and sex wherein men performed more poorly after night call than women as measured by lane variance and crash frequency. Secondary measures, including caffeine, actigraphy, and subjective total sleep time, did not differ between men and women.

Valerian-hops combination and diphenhydramine for treating insomnia: a randomized placebo-controlled clinical trial.

Context: Insomnia is a prevalent health complaint associated with daytime impairments, reduced quality of life, and increased health-care costs. Although it is often self-treated with herbal and dietary supplements or with over-the-counter sleep aids, there is still little evidence on the efficacy and safety of those products.

Objective: To evaluate the efficacy and safety of a valerian-hops combination and diphenhydramine for the treatment of mild insomnia.

Symptoms of gastro-oesophageal reflux disease and the severity of obstructive sleep apnoea syndrome are not related in sleep disorders center patients.

Background: Studies suggest obstructive sleep apnea syndrome (OSAS) frequently manifests in patients with gastroesophageal reflux disease (GERD) and that there may be a causal relationship.

Aim: To determine the relationship between OSAS and symptoms of GERD.

Methods: Consecutive patients referred to the Sleep Disorders Center (SDC) 18 years and older with polysomnographically defined OSAS were evaluated prospectively for GERD using a validated symptoms questionnaire.

Overweight and obese patients in a primary care population report less sleep than patients with a normal body mass index.

Background: Insufficient sleep and obesity are common in the United States. Restricted sleep causes important neurocognitive changes, including excessive daytime sleepiness and altered mood. This may result in work-related injuries and automotive crashes.

Marital satisfaction of wives of untreated sleep apneic men.

Objectives: The purpose of this study was to assess marital satisfaction of the wives of untreated sleep apnea patients.

Design And Methods: A prospective study was carried out that compared the marital satisfaction of wives of men with sleep apnea to the marital satisfaction of wives of men presenting to a primary care physician's office. The study examined three patient groups: 26 wives of men with severe sleep apnea, 19 wives of men with mild sleep apnea, and 19 controls from a primary care physician's office.
