PURPOSE: The role of insomnia in chronic kidney disease (CKD) is controversial. To date, there have been no prospective studies investigating insomnia, CKD and the effect of shift work. We assessed insomnia and CKD risk in a prospective, occupational cohort study. METHODS: A total of 3600 participants with normal kidney function were followed for an average of 4.4 years. Insomnia was assessed using the Athens Insomnia Scale (AIS). CKD was defined as an estimated glomerular filtration rate of <60 mL/min/1...

In mammals, the rhythmic secretion of melatonin from the pineal gland is driven by the circadian clock in the suprachiasmatic nucleus (SCN) of the hypothalamus. The robust nightly peak of melatonin secretion is an output signal of the circadian clock and is supposed to deliver the circadian message to the whole of the organism. Since the circadian system regulates many behavioral and physiological processes, its disruption by external (shift-work, jet-lag) or internal desynchronization (blindness, aging) causes many different health problems...

REVIEW
Manfred Weiss, Rolf Rossaint, Thomas Iber
Anesthesiologists perform a broad spectrum of tasks. However, in many countries, there is no legal basis for personnel staffing of physicians in anesthesia. Also, the German diagnosis related groups system for refunding does not deliver such a basis. Thus, in 2006 a new calculation base for the personnel requirement that included an Excel calculation sheet was introduced by the German Board of Anesthesiologists (BDA) and the German Society of Anesthesiology and Intensive Care Medicine (DGAI), and updated in 2009 and 2015...

Adverse workplace factors such as job stress are reported to be associated with poor physical and mental health of nurses. However, associations between occupational factors and sexual life satisfaction (SLS) of nurses remain understudied. This study investigated SLS of Chinese female nurses of tertiary general hospitals and socio-demographic and occupational factors associated with reduced SLS of nurses. In this cross-sectional survey, 393 Chinese female nurses of four tertiary general hospitals completed a standardized socio-demographic and occupational characteristics questionnaire, Zung's Self-rating Scale for Depression, Job Content Questionnaire, and a self-report SLS question...

BACKGROUND: Postgraduate medical education has undergone significant reorganisation in recent years, with changes to the traditional apprenticeship model and an increasing reliance on shift working. The importance of teamwork in clinical care is well established; however, there is little literature on the extent to which trainees actually feel part of a team in the context of current working patterns. METHOD: This is a qualitative study using semi-structured interviews of medical and surgical trainees...

Work in repeated changing shifts, in general, and night-shifts, in particular, is considered a necessity, encompassing many professions, among them physicians and nurses. This type of work has been shown to adversely affect the normal function of the human body circadian rhythm. This negative influence in turn, is considered to increase characteristic types of morbidity such as metabolic syndrome, type 2 diabetes and increased rate of cardiovascular morbidity. Women working in night-shifts in particular, have been found to face increased rates of breast cancer, as well as menstrual disturbances and decreased fertility...

Bus drivers often work irregular hours or split shifts and their work involves high levels of stress. These factors can lead to severe sleepiness and dangerous driving. This study examined how split shift working affects sleepiness and performance during afternoon driving. An experiment was conducted on a real road with a specially equipped regular bus driven by professional bus drivers. The study had a within-subject design and involved 18 professional bus drivers (9 males and 9 females) who drove on two afternoons; one on a day in which they had driven early in the morning (split shift situation) and one on a day when they had been off duty until the test (afternoon shift situation)...

PURPOSE: The accuracy of a Six Degree of Freedom (6DoF) couch was evaluated using a novel method. METHODS: Cone beam CT (CBCT) images of a 3D phantom (IsoCal) were acquired with different, known combinations of couch pitch and roll angles. Pitch and roll angles between the maximum allowable values of 357 and 3 degrees were tested in one degree increments. A total of 49 combinations were tested at zero degrees of yaw (couch rotation angle). The 3D positions of 16 tungsten carbide BBs, each 4 mm in diameter and arranged in a known geometry within the IsoCal phantom, were determined in the 49 image sets with in-house software...

Fast rotation three-shift working schedules are common in the medical field in Taiwan. This study investigated whether 24 hours off is sufficient for re-adaptation to a daytime routine after working two night shifts (NSs) by comparing changes in cognitive function, anxiety state, and objectively-measured sleep propensity between those working two NSs followed by 24 hours off (n=21, 2NS-off) and an off-duty group (n=21, OD). The results showed that nurses in the 2NS-off group were less alert and had decreased visual attention performance and executive function ability than the OD group during the daytime...

INTRODUCTION: Night-shift works are basically accompanied by reduced cognitive performance, sleepiness, and higher possibility for human error and related incidents. It is therefore crucial to improve individuals' performance and alertness in sensitive places like industries' control room with the ultimate goal of increasing efficiency and reducing the number of possible incidents. Previous research has indicated that blue light is a critical cue for entraining circadian rhythm. As a result, the present study was an attempt to investigate whether blue-enriched white light illumination was a practical strategy to decrease sleepiness and improve cognitive performance during night shifts...

BACKGROUND: Unhealthy eating and physical activity behaviours are common among nurses but little is known about determinants of eating and physical activity behaviour in this population. The present study used a theoretical framework which summarises the many possible determinants of different health behaviours (the Theoretical Domains Framework; TDF) to systematically explore the most salient determinants of unhealthy eating and physical activity behaviour in hospital-based nurses. METHODS: Semi-structured qualitative interviews based on the TDF were conducted with nurses (n = 16) to explore factors that behavioural theories suggest may influence nurses' eating and physical activity behaviour...

Biological evidence suggests that ethno-racial differences in morning-evening type are possible, whereby Blacks may be more likely to be morning type compared to Whites. However, population-level evidence of ethno-racial difference in morning-evening type is limited. In an earlier study, we reported that morning type was more prevalent in Blacks compared to Whites in the United Kingdom (UK) Biobank cohort (N = 439 933). This study aimed to determine if these ethno-racial differences persisted after accounting for an even broader range of social, environmental and individual characteristics and employing an analytic approach that simulates randomization in observational data, propensity score modeling...

Deficits in cognitive functioning associated with shift work are particularly relevant to occupational performance; however, few studies have examined how cognitive functioning is associated with specific components of shift work. This observational study examined how circadian phase, nocturnal sleepiness, and daytime insomnia in a sample of shift workers ( N = 30) were associated with cognitive flexibility during the night shift. Cognitive flexibility was measured using a computerized task-switching paradigm, which produces 2 indexes of flexibility: switch cost and set inhibition...

Light is the most potent time cue that synchronizes (entrains) the circadian pacemaker to the 24-h solar cycle. This entrainment process is an interplay between an individual's daily light perception and intrinsic pacemaker period under free-running conditions. Establishing individual estimates of circadian phase and period can be time-consuming. We show that circadian phase can be accurately predicted (SD = 1.1 h for dim light melatonin onset, DLMO) using 9 days of ambulatory light and activity data as an input to Kronauer's limit-cycle model for the human circadian system...

The endogenous circadian clock drives oscillations that are completely synchronized with the environmental day-night rhythms with a period of approximately 24 hours. Temporal misalignment between one's internal circadian clock and the external solar time often occurs in shift workers and long-distance travelers; such misalignments are accompanied by sleep disturbances and gastrointestinal distress. Repeated exposure to jet lag and rotating shift work increases the risk of lifestyle-related diseases, such as cardiovascular complaints and metabolic insufficiencies...
