- Objectives The present pilot study attempted to investigate the diurnal pattern of cortisol, subjective activation, and mental fatigue among workers scoring high for burnout. The purpose was also to relate the cortisol data to objective sleep data.Methods One group with high (N=9) burnout scores and one with low (N=11) such scores were compared during a workday and a day off.Results The high-burnout group showed higher awakening cortisol during the workday than during the weekend. They also showed higher ratings for activation and mental fatigue during the weekend than the low-burnout group. A higher frequency of arousals during the prior sleep was associated with a higher diurnal amplitude and an earlier diurnal peak of cortisol during the workday.Conclusions The present results, which, due to the small sample size, should be interpreted with caution, may indicate that stress-induced frequency of arousal during sleep could contribute to the diurnal amplitude of cortisol. Furthermore, increased activation and mental fatigue during the weekend may reflect impaired recovery, which is of possible importance in the burnout process.

Prevalence of antibodies specific to Puumala virus among farmers in Sweden

Journal article (peer-reviewed)abstract
- Serological evidence confirmed that the exposure of humans to Puumala virus is firmly restricted to the northern and central parts of Sweden. In addition the evidence indicated that, in this region, farming is associated with an increased risk of contracting hantavirus infection.

Occupational exposure to endocrine-disrupting compounds and biliary tract cancer among men

In: Scandinavian Journal of Work, Environment and Health. - : Scandinavian Journal of Work, Environment and Health. - 0355-3140 .- 1795-990X. ; 33:5, s. 387-396

Journal article (peer-reviewed)abstract
- Objectives This study investigated the association between cancer of the extrahepatic biliary tract and exposure to endocrine-disrupting compounds. Methods Altogether 183 men with histologically confirmed carcinoma of the extrahepatic biliary tract and 1938 matched controls were interviewed between 1995 and 1997 in the frame of an international multicenter case-control study in six European countries (Denmark, France, Germany, Italy, Spain, and Sweden). Selfreported job descriptions were converted to semiquantitative variables (intensity, probability, and duration of exposure) for 14 endocrine-disrupting compounds. The cases were compared with 1421 population controls and 517 colon adenocarcinoma patients. Odds ratios (OR) and 95% confidence intervals (95% CI) were obtained with unconditional logistic regression and adjusted for age, country, and gallstones. Results Occupational exposure to endocrine-disrupting compounds resulted in an OR of 1.4 (95% CI 1.0-2. 1) with no dose-effect relationship for cumulative exposure (low: OR 1.3, 95% CI 0.6-3.0; medium: OR 1.5, 95% CI0.8-2.7; high: OR 1.4, 95% CI 0.9-2.4) (only index participants). The elevated risk was restricted to extrahepatic bile ducts and ampulla Vateri (OR 1.7, 95% CI 1.0-2.6). The adjusted OR for cancer of the extrahepatic biliary tract after exposure to polychlorinated biphenyls was 2.8 (95% CI 1.3-5.9, only index participants). Conclusions The data show some associations between exposure to endocrine-disrupting compounds in the workplace and the risk for cancer of the extrahepatic biliary tract among men, particularly for the extrahepatic bile duct and ampulla of Vater. Polychlorinated biphenyls could possibly be a strong risk factor.

Targeting workload to ameliorate risk of heat stress in industrial sugarcane workers
- 2023

Journal article (peer-reviewed)abstract
- Objective The aim of this study was to quantify the physiological workload of manual laborers in industrial sugarcane and assess the effect of receiving a rest, shade, and hydration intervention to reduce heat stress exposure risk.Methods In an observational study, physiological workload was evaluated for burned cane cutters (BCC), seed cutters (SC) and drip irrigation repair workers (DIRW) using heart rate (HR) recorded continuously (Polar (R)) across a work shift. Workers' percentage of maximal HR (%HRmax), time spent in different HR zones, and estimated core temperature (ECTemp) were calculated. The effect of increasing rest across two harvests was evaluated for BCC and SC.Results A total of 162 workers participated in this study [52 BCC (all male), 71 SC (13 female) and 39 DIRW (16 female)]. Average %HRmax across a work shift was similar between BCC and SC (BCC: 58%, SC: 59%), but lower in DIRW (51%). BCC and SC spent similar proportions of work shifts at hard/very hard intensities (BCC: 13%, SC: 15%), versus DIRW who worked mostly at light (46%) or light-moderate (39%) intensities. SC maximum ECTemp reached 38.2 degrees C, BCC 38.1 degrees C; while DIRW only reached 37.7 degrees C. Females performed at a higher %HRmax than males across work shifts (SC 64% versus 58%; DIRW 55% versus 49%). An additional rest period was associated with a lower average %HRmax across a work shift in BCC.Conclusion In this setting, BCC and SC both undertake very physiologically demanding work. Females maintained a higher workload than male co-workers. Regulated rest periods each hour, with water and shade access, appears to reduce physiological workload/strain.
