Changes in Infection Prevention Practices and Occurrence of Skin Symptoms among Healthcare Workers, Cleaners and Day-care Workers in Norway during the COVID-19 Pandemic.

The COVID-19 pandemic has resulted in increased attention on infection prevention measures. This study aims to assess whether changes in hand hygiene procedures, use of personal protective equipment and moisturizers during the first year of the COVID-19 pandemic were associated with changes in the occurrence of skin symptoms among healthcare workers, cleaners, and day-care workers. A total of 602 participants (40%) responded to an electronic questionnaire, including questions on previous and current occupational exposure and skin problems. Increased frequency of hand washing, use of hand disinfectants, use of disposable gloves and moisturizers were all associated with an increased symptom score on the hands, wrists, forearms. Participants who increased their use of masks or respirators had a higher risk of facial skin symptoms, compared with those with non-increased occupational exposure. In conclusion, a change of behaviour among healthcare workers, cleaners and day-care workers during the first year of the COVID-19 pandemic, with an increase in occupational exposures and use of moisturizers, was associated with higher occurrence of facial skin symptoms and symptoms on the hands, wrists and forearms.

Cleaning at Home and at Work in Relation to Lung Function Decline and Airway Obstruction.

RATIONALE: Cleaning tasks may imply exposure to chemical agents with potential harmful effects to the respiratory system, and increased risk of asthma and respiratory symptoms among professional cleaners and in persons cleaning at home has been reported. Long-term consequences of cleaning agents on respiratory health are, however, not well described. OBJECTIVES: This study aimed to investigate long-term effects of occupational cleaning and cleaning at home on lung function decline and airway obstruction. METHODS: The European Community Respiratory Health Survey (ECRHS) investigated a multicenter population-based cohort at three time points over 20 years. A total of 6,235 participants with at least one lung function measurement from 22 study centers, who in ECRHS II responded to questionnaire modules concerning cleaning activities between ECRHS I and ECRHS II, were included. The data were analyzed with mixed linear models adjusting for potential confounders. MEASUREMENTS AND MAIN RESULTS: As compared with women not engaged in cleaning (ΔFEV1 = -18.5 ml/yr), FEV1 declined more rapidly in women responsible for cleaning at home (-22.1; P = 0.01) and occupational cleaners (-22.4; P = 0.03). The same was found for decline in FVC (ΔFVC = -8.8 ml/yr; -13.1, P = 0.02; and -15.9, P = 0.002; respectively). Both cleaning sprays and other cleaning agents were associated with accelerated FEV1 decline (-22.0, P = 0.04; and -22.9, P = 0.004; respectively). Cleaning was not significantly associated with lung function decline in men or with FEV1/FVC decline or airway obstruction. CONCLUSIONS: Women cleaning at home or working as occupational cleaners had accelerated decline in lung function, suggesting that exposures related to cleaning activities may constitute a risk to long-term respiratory health.

Prevalence of, and work-related risk factors for, hand eczema in a Norwegian general population (The HUNT Study).

BACKGROUND: Chemical exposures at work and at home may cause hand eczema. However, this has been scarcely described for Norway. OBJECTIVES: To investigate the prevalence of, and occupational risk factors for, hand eczema in Norway. METHODS: Among 50 805 respondents (aged ≥20 years) to the third Nord-Trøndelag Health Study (HUNT3), 5757 persons reported ever having hand eczema, and 4206 answered a hand eczema questionnaire. RESULTS: The lifetime prevalences of hand eczema were 8.4% in men and 13.8% in women (p < 0.001), with onset at age ≤10 years in 24% (men) and 20% (women), and onset at age ≥30 years in 37% (men) and 25% (women) (p < 0.001). Work-related hand eczema affected 4.8% of the population, and was most frequently associated with health/social work (29%) and occupational cleaning (20%) in women, and with farming (26%) and industrial occupations (27%) in men. Cleaning detergents (75%) and other chemicals (36%) were the most common exacerbating factors. CONCLUSIONS: The prevalence of hand eczema was 11.3%, and that of work-related hand eczema was 4.8%. Hand eczema was more common in women than in men, but with a later onset in men. Cleaning detergents were the most common aggravating factors. A large proportion of the Nord-Trøndelag population is employed in farming, providing the possibility to identify farming as an important risk factor for hand eczema.

Elevated monocyte phosphorylated p38 in nearby employees after a chemical explosion.

Personalised health surveillance is infrequent or absent in occupational and environmental medicine. The shortage of functional tests in relevant cells and tissues greatly limits our understanding of environmental exposures and associated disease risk. We evaluated single cell signalling in peripheral blood mononuclear cells from 301 individuals in a cross sectional health survey 18 months after a chemical explosion of sulphorous coker gasoline. The accident created a malodourous environment leading to long-term health complaints. Multiple regression analysis revealed T-cell specific elevated phosphorylation of the stress kinase p-p38 (T180/Y182) among tobacco smokers and monocyte-specific elevated phosphorylation in employees at the explosion site. Other studies of the accident reported reduced tear film stability, and more airway obstruction and subjective health complaints among the employees at the accident site. Elevated monocyte p-p38 in the employee group was independent of such health effects, and could therefore be dependent on the sulphuric malodorous environment. The present study proposes signalling status in leukocytes as a scalable biomarker providing information about environmental exposures.

Pain and function in eight hundred and fifty nine patients comparing shoulder hemiprostheses, resurfacing prostheses, reversed total and conventional total prostheses.

PURPOSE: Functional results of reversed total prostheses (RTP) have-to a very limited degree-been compared with those of other shoulder prosthesis types. The aim of our study was to compare results of four different types of shoulder prostheses in terms of function, pain, and quality of life (QoL). METHODS: Questionnaires were completed by 859 patients with shoulder prostheses registered in the Norwegian Arthroplasty Register. Patients with osteoarthritis (OA), rheumatoid arthritis (RA), or fracture sequela (FS) were included. Symptoms and function were assessed using the Oxford Shoulder Score (OSS, scale 0-48), and the EuroQoL-5D (EQ-5D) was used to assess QoL. RESULTS: Best functional results were obtained using conventional total prostheses (TPs) and RTPs -mean OSS improvement 18 and 16 units, respectively, vs 11 with hemiprostheses (HPs). For patients with OA, TPs performed best; for those with RA and FS, RTPs performed best; and those with HPs had the worst results in all diagnostic groups. The greatest improvement in QoL was seen in patients with TPs and RTPs. CONCLUSIONS: Conventional TPs provide the best improvement in pain, function and QoL in OA patients; RTPs are superior in patients with RA and FS.

Good function after shoulder arthroplasty.

BACKGROUND AND PURPOSE: Different results after shoulder arthroplasty have been found for different diagnostic groups. We evaluated function, pain, and quality of life after shoulder arthroplasty in 4 diagnostic groups. PATIENTS AND METHODS: Patients with shoulder arthroplasties registered in the Norwegian Arthroplasty Register from 1994 through 2008 were posted a questionnaire in 2010. 1,107 patients with rheumatoid arthritis (RA), osteoarthritis (OA), acute fracture (AF), or fracture sequela (FS) returned completed forms (65% response rate). The primary outcome measure was the Oxford shoulder score (OSS), which assesses symptoms and function experienced by the patient on a scale from 0 to 48. A secondary outcome measure was the EQ-5D, which assesses life quality. The patients completed a questionnaire concerning symptoms 1 month before surgery, and another concerning the month before they received the questionnaire. RESULTS: Patients with RA and OA had the best results with a mean improvement in OSS of 16 units, as opposed to 11 for FS patients. Both shoulder pain and function had improved substantially. The change in OSS for patients with AF was negative (-11), but similar end results were obtained for AF patients as for RA and OA patients. Quality of life had improved in patients with RA, OA, and FS. INTERPRETATION: Good results in terms of pain relief and improved level of function were obtained after shoulder arthroplasty for patients with RA, OA, and-to a lesser degree-FS. A shoulder arthropathy had a major effect on quality of life, and treatment with shoulder replacement substantially improved it.
