BACKGROUND: Chronic stress is increasing in prevalence and is associated with several physical and mental disorders. Although it is proven that acute stress changes physiology, much less is known about the relationship between physiology and long-term stress. Continuous measurement of vital signs in daily life and chronic stress detection...

Obesity and type 2 diabetes (T2D) have become a global health concern. The prevalence of obesity and T2D is significantly higher in shift workers compared to people working regular hours. An accepted hypothesis is that the increased risk for metabolic health problems arises from aberrantly timed eating behavior, that is, eating out of synchrony...

This study examined associations of chronotype and age with shift-specific assessments of main sleep duration, sleep quality and need for recovery in a cross-sectional study among N = 261 industrial shift workers (96.6% male). Logistic regression analyses were used, adjusted for gender, lifestyle, health, nap behaviour, season of assessment and...

Experimental studies in animals indicate that disruption of the circadian rhythm is carcinogenic, and night work has been suggested to be a probable breast cancer cause in humans. Findings among humans, however are inconsistent, often gathered with retrospective study designs, and only based on specific populations, such as nurses. We used data...

Het werken in de gezondheidszorg wordt gekenmerkt door wisselende werkschema’s, nachtdiensten en beschikbaarheiddiensten. De biologische klok van de mens kan zich daar niet voldoende aan aanpassen. Daardoor kunnen deze diensten leiden tot slaapgebrek en kan men tijdens de nachtdienst vermoeid en minder alert zijn. In industriële bedrijfstakken...

This primary objective of this paper is to discuss the usefulness of melatonin for reducing symptoms of circadian rhythm disturbances in aircrew. Literature and own data of circadian disruptions and symptoms of aircrew were analysed. Considerations concerning the use of melatonin by aircrew are discussed. The main outcomes were as follows....

Long-term ozone simulations from seven regional air quality models, the Unified EMEP model, LOTOS-EUROS, CHIMERE, RCG, MATCH, DEHM and TM5, are intercompared and compared to ozone measurements within the framework of the EuroDelta experiment, designed to assess air quality improvement at the European scale in response to emission reduction...

In this study, the within-animal variation in routinely studied continuous toxicological parameters was estimated from temporal fluctuations in individual healthy nonexposed animals. Assuming that these fluctuations are nonadverse, this within-animal variation may be indicative of the minimal magnitude of the critical effect size (CES). The CES...

Objective: To assess the effect of alarm treatment in children with day- and night-time wetting compared to those with night-time wetting only. Material and Methods: A total of 37 consecutive children (25 boys, 12 girls), all of whom suffered from both day- and night-time wetting, were compared to a group of 21 boys and 16 girls with nocturnal...

This article integrates findings from the literature and new results regarding noise sensitivity. The new results are based on analyses of 28 combined datasets (N=23 038), and separate analyses of a large aircraft noise study (N=10939). Three topics regarding noise sensitivity are discussed, namely, its relationship with noise exposure, its...

The endogenous circadian oscillator (the body clock) is slow to adjust to altered rest-activity patterns. As a result, several negative consequences arise during night work and after time-zone transitions. The process of adjustment can be assessed by measurements of the sleep electroencephalogram (EEG), core temperature or melatonin secretion,...

At older ages, the circadian rhythm of body temperature shows a decreased amplitude, an advanced phase, and decreased stability. The present review evaluates to what extent these changes may result from age-related deficiencies at several levels of the thermoregulatory system, including thermoreception, thermogenesis and conservation, heat loss,...

The present study compares the spectral characteristics of 24-h blood pressure variability estimated invasively at the brachial artery level with those estimated by measurement of blood pressure at the finger artery using the non-invasive Portapres device. Broad-band spectra (from 3 x 10<sup>-5</sup> to 0.5 Hz) were derived from both finger and...

OBJECTIVE: To investigate the effect of exercise training and dietary macronutrient composition on 24 h substrate oxidation in male, obese subjects. DESIGN: A 16 month exercise intervention study was executed, including a weight loss period with a very low energy diet (VLED) for 2 months at the start of the study. SUBJECTS: Twelve male, obese...

A high-performance liquid chromatographic assay was developed for pyridinium crosslinks and pentosidine in mature collagen of a wide variety of connective tissue hydrolysates by a simple two-step isocratic assay using a reversed-phase column. The crosslinks (including the internal standard pyridoxine) were optimally detected by their native...

Raised plasma PAI-1 and t-PA antigen levels are known risk factors for acute coronary events. It is not known whether these factors are related to coronary thrombosis or to a possible atherosclerotic background. Both factors show a marked circadian variation in blood. To assess the effect of atherosclerosis on the fibrinolytic balance, we...

In Sweden the use of daytime running lights (DRL) was made mandatory on 1 October 1977 for all motor vehicles at once, during all seasons and for all areas. According to a study conducted by Andersson and Nilsson (1981) the introduction of DRL resulted in a reduction of 11% of multiple accidents during daytime. In many discussions on the...

In previous studies we observed an increased incidence of hyperplasia in the epithelium of the urinary bladder of rats fed cereal-based stock diet supplemented with 6% monosodium glutamate (MSG) for 3 months. Hyperplasia was not enhanced, however, when 6% MSG was fed in a purified casein diet. Further studies have been conducted to identify the...

The urinary excretion of 3-methylhistidine and creatinine and the urinary 3-methylhistidine to creatinine excretion ratio during day and night were investigated in a group of 103 healthy, normally fed Dutch children (52 boys and 51 girls) aged 2-17 years. The 3-methylhistidine to creatinine ratio of the night urine appeared to be significantly...
