OBJECTIVE To examine clinical correlates of nocturnal eating, a core behavioral symptom of night eating syndrome. METHOD Data from 285 women who had participated in a two-stage screening for binge eating were utilized. Women (n = 41) who reported one or more nocturnal eating episodes in the past 28 days on the eating disorder examination and women who did not report nocturnal eating (n = 244)...

BACKGROUND Although obstructive sleep apnea (OSA) is more common in patients with kidney disease, whether nocturnal hypoxia affects kidney function is unknown. METHODS We studied all adult subjects referred for diagnostic testing of sleep apnea between July 2005 and December 31 2007 who had serial measurement of their kidney function. Nocturnal hypoxia was defined as oxygen saturation (SaO2) ...

There is continuing controversy over whether the pattern of circadian blood pressure (BP) variation that includes a nocturnal decline in BP and a morning pressor surge has prognostic significance for stroke risk. In this study, we followed the incidence of stroke in 1430 subjects aged > or =40 years in Ohasama, Japan, for an average of 10.4 years. The association between stroke risk and the pat...

BACKGROUND Patients with nocturnal hypertension are at higher risk for cardiovascular complications such as myocardial infarction and cerebrovascular insult. Published studies inconsistently reported decreases in nocturnal blood pressure with melatonin. METHODS A meta-analysis of the efficacy and safety of exogenous melatonin in ameliorating nocturnal blood pressure was performed using a rand...

Patients with COPD may show slow, progressive deteriorations in arterial blood gases during the night, particularly during rapid eye movement (REM) sleep. This is mainly due to hypoventilation, while a deterioration of ventilation/perfusion mismatch plays a minor role. The severity of gas exchanges alterations is proportional to the degree of impairment of diurnal pulmonary function tests, part...

BACKGROUND AND OBJECTIVES Nocturnal home hemodialysis provides excellent biochemical and metabolic control of uremia; however, extensive training is necessary and technical barriers exist for intensive home hemodialysis compared with the relative simplicity of peritoneal dialysis. It was hypothesized that nocturnal home hemodialysis is associated with improved quality of life but higher illness...

BACKGROUND Nocturnal desaturation may contribute to long-term pulmonary vascular stress in interstitial lung disease (ILD). We study the prevalence, severity and prognostic utility of nocturnal desaturation across ILD. METHODS ILD patients with overnight oximetry (June 2006-August 2008) were reviewed (n = 134). Significant nocturnal desaturation was considered as > 10% of sleep with SpO2 < 90...

QUESTION In adults who experience nocturnal leg cramps, does stretching of the calf and hamstring muscles each day just before sleep reduce the frequency and severity of the cramps? DESIGN A randomised trial with concealed allocation and intention-to-treat analysis. PARTICIPANTS Eighty adults aged over 55 years with nocturnal leg cramps who were not being treated with quinine. INTERVENTIO...

Nocturnal sleep and daytime napping facilitate memory consolidation for semantically related and unrelated word pairs. We contrasted forgetting of both kinds of materials across a 12-hour interval involving either nocturnal sleep or daytime wakefulness (experiment 1) and a 2-hour interval involving either daytime napping or wakefulness (experiment 2). Beneficial effects of post-learning nocturn...

OBJECTIVE Despite a high incidence of nocturnal hypoglycemia documented by the use of continuous glucose monitoring (CGM), there are no reports in the literature of nocturnal hypoglycemic seizures while a patient is wearing a CGM device. RESEARCH DESIGN AND METHODS In this article, we describe four such cases and assess the duration of nocturnal hypoglycemia before the seizure. RESULTS In t...
