DNA damage in prepared semen is negatively associated with semen quality and fertilisation rate in assisted reproduction technology (ART) treatment.

Sperm DNA contains strand breaks and base damage that can potentially affect reproductive health. This study aims to determine to what extent sperm DNA integrity and alkylation is associated with semen quality and assisted reproduction technology (ART) treatment outcomes, in particular fertilisation and cleavage rates. Male partners of couples attending for infertility treatment were recruited.

Mortality and cancer incidence in the UK glass reinforced plastics manufacturing industry: a cohort study.

Objectives: According to the International Agency for Research on Cancer, styrene is probably carcinogenic for lymphohaematopoietic neoplasms, with insufficient evidence for other cancer sites. We compared mortality and cancer incidence (for the first time) in a UK cohort occupationally exposed to high levels of styrene to that of the general population of England and Wales.

Methods: The follow-up for mortality ran from 1969 to 2022, while the follow-up for cancer incidence ran from 1971 to 2020.

Efficacy and safety of a whole lung lavage program for artificial stone silicosis.

Background: The incidence of silicosis has increased due to occupational silica exposure from artificial stone, with no treatments proven to halt or reverse the disease. Whole lung lavage (WLL) involves the instillation of fluid into the lungs to wash out silica particles and disease-causing inflammatory cells. This study aimed to determine the feasibility, safety, and possible benefit of WLL in patients with artificial stone silicosis.

Assessing occupational styrene exposure in the European and US Glass Reinforced Plastics Industry for the period between 1947 and 2020.

Background: We aimed to develop a method for assessing occupational styrene exposures for application in epidemiological studies on risks of lymphohematopoietic neoplasms and other malignant and non-malignant diseases in the European and the US glass reinforced plastics industries.

Method: We estimated a linear mixed effects model based on individual airborne personal measurements of styrene from the glass reinforced plastics industry in Denmark, Norway, Sweden, UK, and the US. The most suitable model was chosen based on its predictive power as assessed using cross validation with different combinations of predictors; and by comparing their prediction errors.

COVID-19 risk by work-related factors: pooled analysis of individual linked data from 14 cohorts.

Background: SARS-CoV-2 infection rates vary by occupation, but the association with work-related characteristics (such as home working, keyworker or furlough) are not fully understood and may depend on ascertainment approach. We assessed infection risks across work-related characteristics and compared findings using different ascertainment approaches.

Methods: Participants of 14 UK-based longitudinal cohort studies completed surveys before and during the COVID-19 pandemic about their health, work and behaviour.

Impact of extreme bushfire seasons on rates of occupational injury and disease compensation claims in first responders.

Purpose: This study aimed to use workers' compensation (WC) data to explore the impact of the extreme bushfires on injury/disease claim rates amongst first responders (FR) compared with other occupations and off-seasons.

Methods: Data on WC claims for FR (ambulance officers, paramedics, firefighters, police) and other occupations were obtained from WorkSafe Victoria 2005-2022. Negative binomial regression models adjusting for age, gender and number of employed people were used to estimate incident rate ratios of all injury/disease, mental, musculoskeletal and respiratory claims among FR in summer and extreme bushfires compared to off-season/summer and other occupations.

Diagnosis and management of hypersensitivity pneumonitis in adults: A position statement from the Thoracic Society of Australia and New Zealand.

Hypersensitivity pneumonitis (HP) is an immune-mediated interstitial lung disease (ILD) relating to specific occupational, environmental or medication exposures. Disease behaviour is influenced by the nature of exposure and the host response, with varying degrees of lung inflammation and fibrosis seen within individuals. The differentiation of HP from other ILDs is important due to distinct causes, pathophysiology, prognosis and management implications.

Nightshift Rotation Schedule and Fatigue in U.K. and Italian Nurses.

Background: Whether hours on shift might impact adaptation to night shift work is still controversial.

Methods: We conducted a pooled analysis of two studies, including 170 hospital nurses working night shifts, 116 from a United Kingdom study working 12-hour rotating shifts, and 54 from Italy working 8-hour shifts. Both studies used the Epworth Sleepiness Scale (ESS) to detect sleepiness during routine daytime activities as an indicator of fatigue.

Systematic review of impacts of occupational exposure to wildfire smoke on respiratory function, symptoms, measures and diseases.

Background: Wildfire smoke contains numerous hazardous air pollutants which pose serious health risks to humans. Despite this, there has been a limited focus on the assessment of the acute physiological and longer-term respiratory effects of wildfire exposure on firefighters and other emergency workers. Therefore, we undertook a systematic review of the evidence about the respiratory impacts of occupational wildfire smoke exposure among wildfire fighters (WFF).

How can exposure assessment for pesticides in epidemiological studies be improved? Insights from the IMPRESS project.

The IMPRoving Exposure aSSessment Methodologies for Epidemiological Studies on Pesticides (IMPRESS) project (http://www.impress-project.org/) aimed to further the understanding of the performance of pesticide exposure assessment methods (EAMs).

A Longitudinal Study on the Impact of Working From Home During the COVID-19 Pandemic: Self-Rated General Health, Stress, and Work-Family and Family-Work Conflict-Are There Gender and Parental Status Differences?

Objective: The aim of the study is to examine the impact of working from home during the COVID-19 pandemic on general health, stress, work-family, and family-work conflict over-time and identify differences by gender and parental status.

Methods: Trajectory analyses described outcomes over time. Multinomial logistic regression relates the effects of gender, children, and the interaction between them, on group membership based on the latent class growth analyses.

Respiratory and Other Hazard Characteristics of Substances in Cleaning Products Used in Healthcare Centres in England and Wales.

Occupational use of cleaning products can cause asthma in healthcare workers but the cleaning agents responsible are not yet known. This study aimed to identify respiratory and other hazards in cleaning products on the National Health Service (NHS) supply chain online catalogue and used in the NHS. Information on cleaning products, their composition, and H-statements that identified hazard characteristics of chemical substances in them was obtained from chemical safety data sheets (SDSs).

The changing contributory role to infections of work, public transport, shopping, hospitality and leisure activities throughout the SARS-CoV-2 pandemic in England and Wales.

Background: Understanding how non-household activities contributed to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections under different levels of national health restrictions is vital.

Methods: Among adult Virus Watch participants in England and Wales, we used multivariable logistic regressions and adjusted-weighted population attributable fractions (aPAF) assessing the contribution of work, public transport, shopping, and hospitality and leisure activities to infections.

Results: Under restrictions, among 17,256 participants (502 infections), work [adjusted odds ratio (aOR) 2.

Inconsistent health hazard information across safety data sheets for substances in cleaning products used in healthcare centres.

Safety Data Sheets (SDSs) are used to inform downstream users of any hazardous substances in chemical products and advise on how to manage the risks from using these products. It is therefore important that information on the SDS is accurate and consistent. This study investigates the accuracy and consistency of hazard information included in the SDSs of cleaning products used in the healthcare sector in England and Wales.

Trends in occupational respiratory conditions with short latency in the UK.

Background: Occupational short-latency respiratory disease (SLRD; predominantly asthma, rhinitis, hypersensitivity pneumonitis, and occupational infections) prevalence is difficult to determine but certain occupations may be associated with increased susceptibility.

Aims: This study aimed to examine which occupations and industries are currently at high risk for SLRD and determine their respective suspected causal agents.

Methods: SLRD cases reported to the SWORD scheme between 1999 and 2019 were analysed to determine directly standardized rate ratios (SRR) by occupation against the average rate for all other occupations combined.

Thyroid cancer incidence in cohorts exposed in childhood to I released during the Windscale nuclear reactor accident at Sellafield, England, in 1957.

A fire in one of the Windscale nuclear reactors at Sellafield (Cumbria, England) in October 1957 released 1,800 TBq of I (half-life, 8 days) to atmosphere. Measurements of I activity in thyroids of exposed children showed typical thyroid doses of tens of milligray, but with some exceeding 100 mGy. Radiation exposure in childhood is known to increase the risk of thyroid cancer.

Supporting the working life exposome: Annotating occupational exposure for enhanced literature search.

An individual's likelihood of developing non-communicable diseases is often influenced by the types, intensities and duration of exposures at work. Job exposure matrices provide exposure estimates associated with different occupations. However, due to their time-consuming expert curation process, job exposure matrices currently cover only a subset of possible workplace exposures and may not be regularly updated.
