Associations of objective sleep duration and physical activity with risk of heart failure: A prospective cohort study.

Objective: This study aimed to investigate the independent and joint associations of accelerometer-derived sleep duration and physical activity (PA) in different intensities with the risk of incident heart failure (HF).

Methods: The study included 89,572 participants (mean age 62.2 ± 7.

Associations of accelerometer-measured sleep duration with incident cardiovascular disease and cardiovascular mortality.

Study Objectives: This study aimed to determine the associations between accelerometer-measured sleep durations and the risks of incident cardiovascular disease (CVD) and CVD-related mortality.

Methods: A total of 92 261 participants (mean age: 62.4 ± 7.

Circadian rhythm dysfunction and psychopathology in the offspring of parents with bipolar disorder: a high-risk study in the Chinese population.

Background: Understanding the evolution of circadian rhythm dysfunction and psychopathology in the high-risk population has important implications for the prevention of bipolar disorder. Nevertheless, some of the previous studies on the emergence of psychopathologies and circadian dysfunction among high-risk populations were inconsistent and limited.

Aims: To examine the prevalence rates of sleep and circadian dysfunctions, mental disorders and their symptoms in the offspring of parents with (O-BD) and without bipolar disorder (O-control).

Association between accelerometer-measured amplitude of rest-activity rhythm and future health risk: a prospective cohort study of the UK Biobank.

Background: The health effects of rest-activity rhythm are of major interest to public health, but its associations with health outcomes remain elusive. We aimed to examine the associations between accelerometer-measured rest-activity rhythm amplitude and health risks among the general UK population.

Methods: We did a prospective cohort analysis of UK Biobank participants aged 43-79 years with valid wrist-worn accelerometer data.

Association of accelerometer-derived circadian abnormalities and genetic risk with incidence of atrial fibrillation.

Evidence suggests potential links between circadian rhythm and atrial fibrillation (AF). However, whether circadian disruption can predict the onset of AF in the general population remains largely unknown. We aim to investigate the association of accelerometer-measured circadian rest-activity rhythm (CRAR, the most prominent circadian rhythm in humans) with the risk of AF, and examine joint associations and potential interactions of CRAR and genetic susceptibility with AF incidence.

Mechanical properties and acoustic emission characteristics of deep hard coal after segmented high-temperature treatment.

Based on engineering background that local heating of coal seam is uneven due to underground coal gasification, coal-bed gas exploitation via heat injection, spontaneous combustion of coal seam, etc., segmented heating coal sample was used to simulate coal seam under uneven heating condition, and experimental study on mechanical behaviors of coal sample after segmented heat treatment at high temperatures was conducted. Test results show that temperature at 100 °C ~ 400 °C did not reach ignition temperature of deep hard coal for the experiment and was not enough to change main ingredients of coal sample, which less affected compression strength, elastic modulus, acoustic emission behavior of coal sample.

Dim light melatonin patterns in unaffected offspring of parents with bipolar disorder: A case-control high-risk study.

Background: Circadian dysregulation has long been thought to be a key component in the pathophysiology of bipolar disorder (BD). However, it remains unclear whether this dysregulation constitutes a risk factor, manifestation, or consequence of BD. This study aimed to compare dim light melatonin secretion patterns between unaffected offspring of parents with BD (OBD) and offspring of control parents (OCP).

Night Shift Work, MTNR1B rs10830963 Polymorphism, and Prostate Cancer Risk: Findings from a Prospective, Population-Based Study.

Background: The association between night shift work and prostate cancer is controversial. Evidence shows that genetic and environmental factors both contribute to the development of prostate cancer. It is well known that melatonin plays a protective role in prostate cancer.

Posttraumatic stress disorder symptoms in parents and adolescents after the Wenchuan earthquake: A longitudinal actor-partner interdependence model.

Background: Previous research has examined the association between parents' and children's posttraumatic stress disorder symptoms (PTSS) after a variety of traumatic events. However, longitudinal parent-child dyadic studies are scarce.

Methods: Independent self-reports were collected from parent-adolescent dyads (n = 688) after the 2008 Wenchuan earthquake.
