Background: Electronic waste (e-waste) recycling workers in low and middle-income countries have the potential for occupational injuries due to the nature of their work at informal e-waste sites. However, limited research exists on stress, noise, occupational injuries, and health risks associated with this work environment. This study evaluated injury experience, noise exposures, and stress risk factors among e-waste workers at the large recycling site in the Agbogbloshie market, Accra, Ghana.
Methods: Participants completed a survey addressing their work, health status, stress, exposures to several occupational hazards (including noise), use of personal protective equipment at work, and injury experience. A subset of participants also completed personal noise dosimetry measurements. Poisson regression was used to evaluate the association between the number of injuries experienced by participants and various factors evaluated in the survey.
Results: Forty-six male e-waste workers completed the survey, and 26 completed a noise dosimetry measurement. Participants experienced an average of 9.9 ± 9.6 injuries per person in the previous 6 months (range: 1-40). The majority of injuries were lacerations (65.2%), and the most common injury location was the hand (45.7%). Use of personal protective equipment was rare. The mean time-weighted average noise level was 78.8 ± 5.9 dBA. Higher perceived stress, greater age, poorer health status, not using gloves, and involvement in dismantling activities were associated with an increased number of injuries. After controlling for each of these risk factors, perceived stress level and perceived noise exposure were associated with a significantly greater number of injuries.
Conclusions: Our study identified a large number of injuries among informal e-waste recyclers, and we found that higher levels of perceived stress and perceived noise were associated with an increased number of occupational injuries, even after controlling for other injury risk factors.

Purpose: This study aimed to explore the narratives of people with acquired brain injury (ABI) who participated in the Unmasking Brain Injury project. Through this inquiry, the multifaceted nature of wellbeing after ABI was described in the narratives, which were characterized by identifying facilitators and barriers to overall wellness.
Methods: A mixed-methods approach was utilized for this study.
The therapeutic alliance is central to occupational rehabilitation, particularly for immigrant workers who face unique challenges of migration and of social and occupational integration. This study explores the development and maintenance of this alliance between immigrant workers with compensated work injuries and their care providers during work rehabilitation. Using ethnography, semi-structured interviews, and focus groups, the qualitative case study involved 7 injured immigrant workers and their interdisciplinary clinical team.

Introduction: Electrical injuries (EIs) represent a significant clinical challenge due to their complex pathophysiology and variable presentation, ranging from minor burns to severe internal organ damage. Despite their prevalence in both; domestic and occupational settings, there remains a rareness of systematic guidelines and comprehensive literature to aid clinicians in effectively managing these injuries. Understanding these factors is crucial for developing protocols that can mitigate the risk of delayed complications, such as cardiac arrhythmias, in patients who initially appear stable.

Background: Occupational accidents, injuries, and diseases remain critical health concerns. Designing and implementing checklists for occupational risk prevention are key strategies to mitigate these accidents and their adverse effects. However, due to the diverse nature of occupational hazards, these checklists tend to encompass a substantial number of prevention practices, making their full implementation challenging in terms of financial and human resources.
