Associations Between Objective Sleep and Ambulatory Blood Pressure in a Community Sample

Objective Epidemiologic data increasingly support sleep as a determinant of cardiovascular disease risk. Fewer studies have investigated the mechanisms underlying this relationship using objective sleep assessment approaches. Therefore, the aim of this study was to examine associations between daily blood pressure (BP) and both objectively assessed sleep duration and efficiency. Methods A diverse community sample of 300 men and women aged 21 to 70 years, enrolled in the North Texas Heart Study, participated in the study. Actigraphy-assessed sleep was monitored for two consecutive nights with ambulatory BP sampled randomly within 45-minute blocks on the first and second day as well as the second night. Results Overall, sleep duration results paralleled those of sleep efficiency. Individuals with lower sleep efficiency had higher daytime systolic (B = −0.35, SE = 0.11, p = .0018, R2 = 0.26) but not diastolic BP (B = −0.043, SE = 0.068, p = .52, R2 = 0.17) and higher nighttime BP (systolic: B = −0.37, SE = 0.10, p

rno R Abstract While evidence-based interventions can help the substantial number of veterans diagnosed with comorbid PTSD and depression, an emerging literature has identified sleep disturbances as predictors of treatment nonresponse. More specifically, predicting effects of residual insomnia and nightmares on postintervention PTSD and depressive symptoms among veterans with comorbid PTSD and depression has remained unclear. The present study used data from a clinical trial of Behavioral Activation and Therapeutic Exposure (BA-TE), a combined approach to address comorbid PTSD and depression, administered to veter...

tter TC Abstract Discrepancy between objective and subjective sleep parameters is a frequent symptom in persons suffering from insomnia. Since it has an impairing effect on daytime well-being and neglects possible positive objective improvements, it would be useful if it was treated. Apart from hypnotics, cognitive behavior therapy (CBT-I) is the therapy of choice for chronic forms of insomnia. However, there is limited information about whether CBT-I can also improve subjective-objective sleep discrepancy. We investigated a large sample of patients showing chronic forms of insomnia regarding their subjective-obje...

ntilde;as R Abstract The pentapeptides methionine-enkephalin and leucine-enkephalin belong to the opioid family of peptides, and the non-opiate peptide adrenocorticotropin hormone (ACTH) to the melanocortin peptide family. Enkephalins/ACTH are derived from pro-enkephalin, pro-dynorphin or pro-opiomelanocortin precursors and, via opioid and melanocortin receptors, are responsible for many biological activities. Enkephalins exhibit the highest affinity for the δ receptor, followed by the μ and κ receptors, whereas ACTH binds to the five subtypes of melanocortin receptor, and is the only member of the ...

ConclusionsAccording to this study, in our institution, in cases of major tonsillar hypertrophy, simultaneous soft palate surgery had no significant impact on the success rate, regardless of soft palate length. Associating soft palate surgery with palatine tonsillectomy does not seem mandatory to increase the success rate.Level of evidenceIII. Retrospective comparative study

ConclusionHigh prevalence of particularly cardiovascular comorbidity among patients with insomnia-like symptoms was linked to nocturnal hypoxemia. Considerable differences in clinical presentation were found among OSA patients across Europe. Our data underline that physicians should ask their patients with suspected OSA also for insomnia symptoms. It remains to be explored if a reduction of nocturnal hypoxemia predicts the improvement of insomnia symptoms.

This study aimed to explore the association between thyroid dysfunction and OSA in the adults with prediabetes or diabetes mellitus type 2, who have very high prevalence of OSA.MethodsOSA was assessed using an in-home monitoring device, WatchPAT200. OSA severity was measured using apnea-hypopnea index (AHI), oxygen desaturation index (ODI), minimum oxygen saturation (minO2), and time spent under oxygen saturation

There is emerging evidence of a relationship between short sleep duration and poor quality of sleep with overweight and obesity. This has been clearly demonstrated in adults and there is increasing evidence of this relationship in children and adolescents. One area that needs more study is whether sleep patterns early in life are important for the development of subsequent obesity. This may be complicated because sleep in infants is more fragmented because it is interspersed with feedings. In this volume of The Journal, Tuohino et al report the results of their study that evaluated whether shorter sleep duration at 3 and 8...
