Rising temperatures and heat events may affect workers, especially women, by increasing the risk of Heat Related Illnesses (HRIs). We conducted a cross-sectional study among 903 women in outdoor and indoor sectors. We measured Wet Bulb Globe Temperature (WBGT) and physiological Heat Strain Indicators (HSI), as well as self-reported symptoms of HRIs using a HOTHAPS questionnaire. Multivariate Logistic Regression models were used to compare the heat risks. WBGT exposures were high in both the outdoor (Avg. WBGT = 28.8 °C ± 2.4 °C) and indoor (Avg. WBGT = 28.7 °C ± 3.5 °C) sectors. Outdoor Women Workers (OWW) reported higher HRI symptoms (94%vs.81%), and heat exposures were positively correlated with HRIs (AOR: 3.7; 95%CI: 2.4-6.1). OWW showed a 1.5-fold higher risk of measured HSI above safe limits (95%CI: 1.1-2.1) and a 2.1-fold higher risk of urogenital issues (95%CI: 2.1-3.8) than Indoor Women Workers (IWW). Due to direct sun exposure, intensive labor, and a lack of welfare facilities, OWW has a higher HRI risk.

Pigeon breeders are exposed to high levels of fine particulate organic matter in the pigeon lofts. A total of 6,704 pigeon breeders and their 1:30 sex and age-matched referents from the general Danish population were followed from 1980 or first year of membership in the Danish Racing Pigeon Association, until first event of myocardial infarction, emigration, death, or end of study, on December 31, 2013. Information on outcomes and covariates was obtained by record linkage with national registers. Stratified Cox regression models estimated the hazard ratio of myocardial infarction, adjusted for occupation and residence at the start of follow-up. Compared with referents, pigeon breeders had an adjusted hazard ratio of 1.14 (95% CI: 1.05-1.22) for myocardial infarction. Exposure to pigeon-derived organic dust may increase the risk of myocardial infarction, but this finding needs to be corroborated.

Purpose: The aim of this study is to determine nurses' awareness, worry and hope levels about climate change.

Design and methods: This cross-sectional study was conducted with 511 nurses. Data were collected using a Personal Information Form, the Global Climate Change Awareness Scale, the Climate Change Worry Scale, and the Climate Change Hope Scale.

Findings: The mean scores of the participating nurses obtained from the Climate Change Awareness Scale (71.72 ± 18.11) and Climate Change Worry Scale (35.36 ± 10.51) and Climate Change Hope Scale (38.67 ± 8.80) were moderate, and there was a significant positive correlation between them.

Conclusions: The nurses who participated in this study had moderate levels of climate change-related awareness, worry, and hope. As their climate change awareness scores increased, their worry and hope scores also increased. Interventions that will raise climate change awareness in nurses such as education programs and awareness campaigns may increase their levels of worry and hope that will mobilize them for the solution to the climate change problem.

Introduction: This study examined emergency physicians across the country in terms of Impostor Phenomenon (IP) and Burnout Syndrome (BoS). We aimed to evaluate the possible relationship between IP and BoS and determine which demographic characteristics pose a risk for IP and BoS.

Methods: This quantitative cross-sectional study consists of Clance Impostor Phenomenon Scale (CIPS) and Maslach Burnout Inventory (MBI) which were filled out online by the participants. A total of 389 volunteers participated in the study.

Results: The median age of participants was 30 years (Q1-Q3=27-35) and 57.3% (223) of them were male. The frequency of significant/intense IP was higher in women (28.9%) than in men (17%) (p=0.020). High emotional exhaustion and low personal accomplishment were more common in women than in men (71.7% vs 60.6% and 50% vs 31%, respectively). The median age of participants classified as none to mild IP was 34 years. It was 28 years in significant/intense IP. It was detected that the severity of IP increased as the participants got younger (p<0.001). Significant/intense IP was most common in residents (29%). The residents also had the highest frequency of depersonalization (73.5%). The frequency of moderate to intense IP was the least in participants who worked at a university hospital (74.6%).

Conclusion: The results of this study indicated that IP and BoS are more common in residency. The increased frequency of IP and BoS in young female physicians may be attributed to hierarchical working arrangements and worry about academic performance. Experienced physicians with high levels of academic self-consciousness exhibited a low frequency of IP. Additionally, this study identified a moderate correlation between IP and BoS.

Hypersensitivity pneumonitis (HP), also known as extrinsic allergic alveolitis, is the most common interstitial lung disease in children, but remains rarely recognized in the pediatric population. Early recognition of triggering factors and a high index of suspicion of HP could lead to timely diagnosis and individualized treatment. This study aimed to present four clinical cases of HP reported between 2012 and 2022 in Lithuania to improve the suspicion of the disease in children.

This study aims to explore the barriers that prevent the implementation of occupational health and safety regulations in Lebanon. A qualitative approach was adopted including a document analysis of the available legal documents pertaining to occupational health and safety at the national level and ten in-depth interviews with professionals in the field of occupational health and safety in Lebanon. Our findings show that the implementation of the occupational health and safety regulations in Lebanon is hindered by several barriers including the lack of a holistic legal framework, lack of promotion of a health and safety culture at work, insufficient number of labor inspectors, insufficient training for labor inspectors, lack of necessary tools and equipment, lack of an adequate documentation system, hierarchy within the Ministry of Labor, weak compliance, and the influence of the informal sector.

Asbestos is a mineral with unique physical and chemical properties that make it highly resistant to heat, fire, and corrosion. Nevertheless, exposure to asbestos fibers has been linked to serious health problems, including lung cancer, mesothelioma, and asbestosis. Despite the ban on asbestos usage, asbestos-related diseases are still a major cause of morbidity and mortality worldwide. Analyzing the mineralogical features and fiber analysis of asbestos in biological materials is critical for scenarios where an asbestos exposure history cannot be obtained, a clinical diagnosis cannot be made, or legal aspects necessitate further investigation. This review outlines the mineralogical features and fiber analysis techniques of asbestos in biological materials.

Environmental risk factors associated with malignancy of pediatric neuroblastic tumours are not well-known and few studies have examined the relationship between industrial emissions and neuroblastic tumour diagnosis. A retrospective case series of 310 patients was evaluated at a tertiary hospital in Toronto, Canada between January 2008, and December 2018. Data from the National Pollutant Release Inventory (NPRI) were used to estimate exposure for a dozen chemicals with known or suspected carcinogenicity or embryotoxicity. Comparative analysis and predictive logistic regression models for malignant versus benign neuroblastic tumours included variables for residential proximity, number, and type of industries, mean total emissions within 2 km, and inverse distance weighted (IDW) quantity of chemical-specific industrial emissions estimated within 10 and 50 km of cases. No significant difference was seen between malignant and benign cases with respect to the mean nearest residential distance to industry, the number or type of industry, or the mean total quantity of industrial emissions within a 2 km radius of residential location of cases. However, there were statistically significant differences in the interpolated IDW emissions of dioxins and furans released between 1993 and 2019 within 10 km. Concentrations were significantly higher in malignant neuroblastic tumours at 1.65 grams (g) toxic equivalent (TEQ) (SD 2.01 g TEQ) compared to benign neuroblastic tumours at 1.13 g TEQ (SD 0.84 g TEQ) (p = 0.05). Within 50 km 3 years prior to diagnosis, malignant cases were exposed to higher levels of aluminum, benzene, and nitrogen dioxide (p = 0.02, p = 0.04, and p = 0.02 respectively). Regression analysis of the IDW emissions within a 50 km radius revealed higher odds of exposure to benzene for malignant neuroblastic tumours (OR = 1.03, CI: 1.01-1.05, p = 0.01). These preliminary findings suggest a potential role of industrial emissions in the development of malignant pediatric neuroblastic tumours and underscore the need for further research to investigate these associations.

This study sought to investigate the evolution of cardiovascular disease (CVD) risk factors in career firefighters. A questionnaire was sent to a cohort of 233 Québec career firefighters in 2015 and 2021 to collect demographic and occupational information and the presence of CVD risk factors. Ninety-six (96) firefighters (1 female) responded to the questionnaire in 2015 and 2021. Body weight (2015: 88.3 ± 10.9, 2021: 89.6 ± 10.7 kg, p = 0.01), body mass index (2015: 27.6 ± 3.2, 2021: 28.0 ± 3.0 kg/m², p = 0.01), number of CVD risk factors (2015: 1.1 ± 1.0, 2021: 1.3 ± 0.9 CVD risk factors, p = 0.05), and proportion of firefighters with at least 1 CVD risk factor (2015: 71, 2021: 82%, p = 0.02) increased. Overall, our results highlight an aggravation of several CVD risk factors in Québec career firefighters over the years.

There are concerns over traffic-related air pollution in Uganda's capital, Kampala. Individuals in the transportation sector are hypothesized to be at greater risk for exposure to volatile organic compounds, given their proximity to vehicle exhaust. Silicone wristbands are a wearable technology that passively sample individuals' chemical exposures. We conducted a pilot cross sectional study to measure personal exposures to volatile organic compounds among 14 transportation workers who wore a wristband for five days. We analyzed for 75 volatile organic compounds; 33 chemicals (35%) were detected and quantified in at least 50% of the samples and 15 (16%) chemicals were detected and quantified across all the samples. Specific chemicals were associated with participants' occupation. The findings can guide future large studies to inform policy and practice to reduce exposure to chemicals in the environment in Kampala.
