Underreporting of Work-Related COVID-19 Cases in Norway.

Background: This register-based study provides a profile of work-related Covid-19 cases reported by physicians to the Norwegian Labor Inspection Authority (NLIA). Methods: All the reports of work-related Covid-19 cases reported by a physician to the NLIAs Registry for Work-Related Diseases (RAS) between February 2020 and February 2022 were included. Descriptive statistics and the incidence rate of reported cases were computed for age, gender, and occupation. Results: Two hundred and seventeen work-related Covid-19 cases were reported to RAS during the study period. Sixty-five percent of the cases were females (n = 141), and 35 percent (n = 76) were males. Doctors, nurses, and ambulance personnel yielded higher incidence rates than other healthcare and nonhealthcare occupations. Conclusions: This study indicates that women aged 25-39 and employed in the healthcare sector had the highest reported incidence and number of work-related Covid-19 cases. Physician underreporting of work-related Covid-19 cases is an important finding. Plausibly, underreporting is more substantial for at-risk non-healthcare occupations such as waiters, bartenders, food couriers, and taxi drivers than occupations in healthcare.

Physician Notified Work-Related Diseases Among Farmers in Norway: Data from 2007 - 2016.

Introduction: This study provided a profile of work-related diseases in the farming sector notified by physicians to the Norwegian Labor Inspection Authority's (NLIA) Registry for Work-Related Diseases (RAS) over a 10-year period.Methods: Data for the occupational code "farmers" were extracted from RAS for the period 2007-2016. We performed a descriptive analysis to obtain frequency, percentage, and incidence distribution of the data. We also explored the relationship of the notified diagnosis with gender, age, occupational exposures and the type of reporting physicians.Results: Four hundred and sixty-nine cases of work-related diseases among farmers were notified in the period 2007-2016. Eighty-seven percent of the reported cases were males. The incidence of work-related diseases for the entire study period was computed to be 114/100 000 workers. The incidence and number of cases notified were highest among males and for the age group 55-74 years. Noise was the most frequently reported occupational exposure accounted for 291 cases. Hearing loss constituted for 62% of the notified cases, followed by respiratory diseases that accounted for 20% of the cases. Forty-eight cases of skin diseases, while only a few cases of musculoskeletal (n = 7) and mental disorders (n = 1) were notified. There was a strong association (λ = 0.51) between occupational exposure and notified diagnosis, and a moderate association (λ = 0.32) between type of reporting physician and the notified diagnosis.Conclusion: This profile of the physician notified work-related diseases among farmers in Norway yielded a suppressed estimate of the actual incidence of cases. The biased distribution of nature and number of work-related diseases amongst farmers is primarily attributed to the significant undercount of cases. Physician underreporting of cases to the NLIA coupled with lack of Occupational Health Services coverage of workers in the farming sector contributes to this undercount of cases.

Work environment factors and work sustainability in Norwegian cooks.

OBJECTIVES: Cooks have increased morbidity and mortality. A high turnover has also been reported. We aimed to elucidate work environment and work sustainability in Norwegian cooks. MATERIAL AND METHODS: A questionnaire inquiring about working conditions and work participation was sent to 2082 cooks who had qualified from 1988 onwards. Of these, 894 responded. Time at work was analyzed with Kaplan-Meier plots and possible determinants for quitting work as a cook was analyzed with Cox regression. RESULTS: The median time at work was 16.6 years. There were differences in sustainability between types of kitchens for both sexes (p = 0.00). The median time in the profession was 9.2 years for the cooks in restaurants, while the cooks in institutions and canteens showed a substantially higher sustainability with 75.4% still at work after 10 years, and 57% still at work after 20 years in the profession. Of those still at work as a cook, 91.4% reported a good or very good contentment, and the 67.4% who expected to stay in the profession the next 5 years frequently answered that excitement of cooking, the social working environment, and the creative features of cooking were reasons to continue. Musculoskeletal complaints were the most common health-related reason for leaving work as a cook, while working hours was the most common non-health-related reason. CONCLUSIONS: There are significant differences in work sustainability between the cooks in the different types of kitchens. The identified determinants for length of time in the occupation can be used for preventive purposes.

Psychosocial working conditions and sickness absence in a general population: a cohort study of 21,834 workers in Norway (The HUNT Study).

OBJECTIVE: To examine the associations between psychosocial working conditions and sickness absence. METHODS: Data for 21,834 employed adults from the Nord-Trøndelag Health Study (HUNT) were linked to the sickness benefit register and sickness absence during 1 year after survey participation was analyzed with logistic regression. RESULTS: A one unit change on a 0 to 3 self-reported job demand scale was associated with a fully adjusted 24% and 25% increased odds of sickness absence in men and women, respectively. A one unit change on a 0 to 3 scale for self-reported support at work was associated with a fully adjusted 13% and 17% reduced odds of sickness absence in men and women, respectively. CONCLUSIONS: The results of this study indicate that demands, and to some extent support, at work might influence sickness absence-also when adjusting for a detailed categorization of occupations.

Intestinal injury after thoracic aortic cross-clamping in the pig.

BACKGROUND: The mucosal surface epithelium is an essential part of the functional intestinal barrier, but its structural response to ischemia/reperfusion is only partly characterized. The purpose of this study was to provide a detailed morphological evaluation of intestinal surface epithelium after aortic cross-clamping. MATERIAL AND METHODS: Pigs were subjected to thoracic aortic cross-clamping for 60 min and subsequent reperfusion for 120 min. Tissue blood flow and high-energy phosphates were measured with microspheres and HPLC, respectively. Urinary excretion of (14)C polyethylene glycol (MW 4000 Da) (PEG-4000), loaded into an intestinal loop, provided an index of intestinal permeability. RESULTS: Jejunal blood flow was restored at 10 min after aortic declamping. Denudation of the basement membrane of the intestinal villi tips, as a consequence of epithelial shedding, increased markedly during the initial 60 min of reperfusion (P = 0.002). During the following 45 min, the denuded basement membrane was partly covered with low cuboidal and squamous-shaped cells extending lamellipodia over a wavy basement membrane. Restoration of ATP at 60 min after aortic declamping correlated inversely to the extent of denuded basement membrane (r = 0.75, P = 0.032). Permeability of PEG-4000 increased markedly after aortic declamping and was linearly correlated to the area of denuded basement membrane (r = 0.87, P = 0.01). CONCLUSIONS: Reperfusion for 2 h after aortic cross-clamping is associated with initial aggravation of ischemia-induced injury in the porcine jejunum, but thereafter with restitution of the surface epithelium. Restoration of ATP may be important to avoid intestinal injury after ischemia. Increased permeability of a macromolecule in response to reperfusion is closely correlated to injury of the surface epithelium.
