BACKGROUND: Duty hour limits have shortened intern shifts without concurrent reductions in workload, creating work compression. Multiple admissions during shortened shifts can result in poor training experience and patient care. OBJECTIVE: To relieve work compression, improve resident satisfaction, and improve duty hour compliance in an academic internal medicine program. METHODS: In 2014, interns on general ward services were allotted 90 minutes per admission from 3 pm to 7 pm, when the rate of admissions was high...

So-called CO2 flux partitioning algorithms are widely used to partition the net ecosystem CO2 exchange into the two component fluxes, gross primary productivity and ecosystem respiration. Common CO2 flux partitioning algorithms conceptualize ecosystem respiration to originate from a single source, requiring the choice of a corresponding driving temperature. Using a conceptual dual-source respiration model, consisting of an above- and a below-ground respiration source each driven by a corresponding temperature, we demonstrate that the typical phase shift between air and soil temperature gives rise to a hysteresis relationship between ecosystem respiration and temperature...

OBJECTIVE: We aimed to compared sleep characteristics associated with quick returns (QRs, <11 hours between shift intervals) with those associated with other common shift transitions. METHODS: Sixty-seven nurses completed a 2-week work and sleep diary (94.0% female, mean age 47.7 years). A multilevel fixed effects model was used to examine the sleep in QRs compared with two consecutive night shifts, two consecutive evening shifts, and two consecutive day shifts, respectively...

Vocational reintegration provides a key goal for patients after myocardial infarction both from social as well as from individual perspective. Return to work rate is determined by medical parameters such as left ventricular function, residual ischemia and rhythm stability, as well as by occupational requirement profile such as the blue or white collar work, night shifts and the way capacity. Psycho-social factors including depression, self-assessment of their own situation and pre-existing cognitive impairment to a large extent determine the reintegration...

Exposure to workplace hazards, such as dust, solvents, and fumes, has the potential to adversely affect the health of people. However, the effects of workplace hazards on health may differ when exposure occurs at different times in the circadian cycle, and among people who work longer hours or who do not obtain adequate sleep. The aim of the present study was to document exposures to workplace hazards across a national sample of New Zealanders, comparing people who work a standard 08:00 -17:00 h Monday-to-Friday working week (Std hours) and those who do not (N-Std hours)...

This study aimed to evaluate the effects of an intervention on objective working-hour characteristics. The intervention involved making modifications to the collective agreement that would limit employees' entitlement to time off as compensation. The intervention group consisted of 493 and the control group of 2303 health and social care shift workers, respectively. We analysed the objective pay roll-based working-hour data for 2012-2013, which we obtained from employers' records, using the repeated measures mixed model...

Pelteobagrus vachellii, an important freshwater fish in China, shows predominantly nocturnal behavior. To better understand the growth and molecular mechanisms underlying altered feeding times in this species, we studied the growth and liver transcriptome of P. vachellii with shifted feeding times. In this study, a 9-week growth trial was conducted on male P. vachellii (mean weight±S.E.=1.05±0.36g) with commercial feed. Two triplicate groups of fish were fed either at 0800 (day group, control) or at 2000 (night group) with the same amount of feed...

BACKGROUND. In humans, a single light exposure of 12 minutes and multiple-millisecond light exposures can shift the phase of the circadian pacemaker. We investigated the response of the human circadian pacemaker to a single 15-second or 2-minute light pulse administered during the biological night. METHODS. Twenty-six healthy individuals participated in a 9-day inpatient protocol that included assessment of dim light melatonin onset time (DLMO time) before and after exposure to a single 15-second (n = 8) or 2-minute (n = 12) pulse of bright light (9,500 lux; 4,100 K fluorescent) or control background dim light (<3 lux; n = 6)...

OBJECTIVE: This study assessed the degree of interindividual responses in energy intake (EI) to an imposed sleep restriction versus habitual sleep duration protocol. It also investigated participant (age, sex, ethnicity, and BMI) and study (study site and protocol order) characteristics as potential contributors to the variance in EI responses to sleep restriction between individuals. METHODS: Data from two randomized crossover trials were combined. All participants (n = 43; age: 31 ± 7 years, BMI: 23 ± 2 kg/m(2) ) were free of medical/sleep conditions, were nonsmokers, reported not performing shift work, and had an average sleep duration of 7 to 9 hours per night...

BACKGROUND: Obesity has been cited as a public health problem in both developing and developed countries. There is evidence that rates of obesity have increased among healthcare workers (HCWs) in South Africa (SA), especially those who do night shifts, with a negative effect on health. Perceptions of body weight contribute significantly to the desire to lose weight or not to do so. OBJECTIVE: To determine perceptions of HCWs regarding their own body weight in selected public hospitals in Mpumalanga Province, SA...

PURPOSE: This study aimed to identify risk factors of unplanned extubation in intensive care unit (ICU) patients with mechanical ventilation using a patient safety model. METHODS: This study was designed to be a case-control study. Data collection sheets, including 29 risk factors of unplanned extubation in mechanically ventilation patients were retrospectively collected based on a patient safety model over 3 years. From 41,207 mechanically ventilated patients, 230 patients were identified to have unplanned extubation during their ICU stay...

Various lines of research have identified a number of factors that can impair a person's ability and motivation to exercise self-control, here self-regulation, in the face of a tempting object (e.g., food, sex, alcohol/drugs, smoking). Each of these in-situ factors-the availability of the tempting object, one's desire for it, and impaired affective and cognitive functioning (most notably from sleep-related fatigue, daily 'wear and tear', and intoxication)-makes self-regulation more difficult, and even more so when they co-occur...

The characteristics of the cycles of activity and rest stand out among the most intensively investigated aspects of circadian rhythmicity in humans and experimental animals. Alterations in the circadian patterns of activity and rest are strongly linked to cognitive and emotional dysfunctions in severe mental illnesses such as Alzheimer's disease (AD) and major depression (MDD). The proinflammatory cytokine interleukin 6 (IL-6) has been prominently associated with the pathogenesis of AD and MDD. However, the potential involvement of IL-6 in the modulation of the diurnal rhythms of activity and rest has not been investigated...

Since the publication of the IARC Monograph in 2007 classifying night shift work leading to a disruption of circadian rhythm as probably carcinogenic to humans, there is an increasingly growing interest in understanding how circadian disruption may play a role in cancer development. This systematic review provides a comprehensive update on epidemiological evidences on circadian disruption and prostate cancer since the last review published in 2012. We identified 12 new studies evaluating the effects of several circadian disruptors such as night shift work, sleep patterns, and circadian genes in prostate cancer risk...

Food intake during the rest phase promotes circadian desynchrony, which has been associated with metabolic diseases. However, the link between circadian rhythm and metabolic alterations is not well understood. To investigate this issue, we explored the circadian rhythm of c-Fos immunoreactivity (IR) in rats fed during the day, during the night or with free access to food for 3 weeks. The analysis was focused on the hypothalamic nuclei, which are interconnected and involved in the control of energy homeostasis and/or arousal: lateral hypothalamus (LH), perifornical area, arcuate, ventrolateral pre-optic (VLPO) and tuberomammillary nuclei...
