  • Perception of Whole Day Workload as a Mediator Between Activity Engagement and Stress in Workers with Type 1 Diabetes
    Perception of Whole Day Workload as a Mediator Between Activity Engagement and Stress in Workers with Type 1 Diabetes
    Gonzalez JS ;
    Hernandez R
    2024/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    Associations between various forms of activity engagement (e.g. work, leisure) and the experience of stress in workers have been widely documented. The mechanisms underlying these effects, however, are not fully understood. Our goal was to investigate if perceived whole day workload accounted for the relationships between daily frequencies of activ ...

    2024/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    Background: People with chronic obstructive pulmonary disease (COPD) occasionally develop acute exacerbation of COPD-a potentially fatal condition. Psychological distress was associated with acute exacerbation of COPD. However, the evidence on the effect of psychological distress on acute exacerbation of COPD remains unclear. Objective: The aim of ...

    Battram T
    2024/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    Circulating vitamin B12 concentrations during pregnancy are associated with offspring health. Foetal DNA methylation changes could underlie these associations. Within the Pregnancy And Childhood Epigenetics Consortium, we meta-analysed epigenome-wide associations of circulating vitamin B12 concentrations in mothers during pregnancy (n=2,420) or cor ...

  • Prospective Validity Assessment of a Friction Prediction Model Based on Tread Outsole Features of SlipResistant Shoes
    Prospective Validity Assessment of a Friction Prediction Model Based on Tread Outsole Features of Slip-Resistant Shoes
    Beschorner KE ;
    Deschler C
    2024/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    Shoe outsole design strongly influences slip and fall risk. Certain tread features that can be readily measured have been shown to predict friction performance. This research aimed to replicate those findings and quantify their ability to predict slipping. Participants (n = 34) were exposed to a low friction oil-coated floor surface, while wearing ...

    2024/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    In 2023, the National Institute for Occupational Safety and Health (NIOSH) Total Worker Health® (TWH) Program will mark two decades since its inception as a simple, yet paradigm-shifting, concept that all work should both be safe and enhance the health and well-being of workers. Since its founding, the NIOSH TWH Program has strived to be evergreen, ...

  • Molecular Activation of NLRP3 Inflammasome by Particles and Crystals A Continuing Challenge of Immunology and Toxicology
    Molecular Activation of NLRP3 Inflammasome by Particles and Crystals: A Continuing Challenge of Immunology and Toxicology
    Lim CS ;
    Ma Q
    2024/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    Particles and crystals constitute a unique class of toxic agents that humans are constantly exposed to both endogenously and from the environment. Deposition of particulates in the body is associated with a range of diseases and toxicity. The mechanism by which particulates cause disease remains poorly understood due to the lack of mechanistic insi ...

    2024/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    Both pre-race meet and daily turf surface condition measurements are required by regulations adopted as part of the Horseracing Integrity and Safety Act (HISA). The Orono Biomechanical Surface Tester (OBST) is the primary device used for characterizing a racing surface and is used for the pre-meet inspections. Tools that are better suited for the d ...

    Grajewski, Barbara A. ;
    Johnson CY
    2024/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    Objectives Flight attendants perform physically demanding work such as lifting baggage, pushing service carts and spending the workday on their feet. We examined if more frequent exposure to occupational physical demands could explain why previous studies have found that flight attendants have a higher reported prevalence of menstrual cycle irregul ...

  • SexSpecific DNA Methylation in Saliva from the MultiEthnic Future of Families and Child Wellbeing Study
    Sex-Specific DNA Methylation in Saliva from the Multi-Ethnic Future of Families and Child Wellbeing Study
    Bakulski KM ;
    Dou JF
    2024/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    The prevalence and severity of many diseases differs by sex, potentially due to sex-specific patterns in DNA methylation. Autosomal sex-specific differences in DNA methylation have been observed in cord blood and placental tissue but are not well studied in saliva or in diverse populations. We sought to characterize sex-specific DNA methylation on ...

    2024/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    Difference-in-differences is undoubtedly one of the most widely used methods for evaluating the causal effect of an intervention in observational (i.e., nonrandomized) settings. The approach is typically used when pre- and postexposure outcome measurements are available, and one can reasonably assume that the association of the unobserved confounde ...

    January 2024 | National Institute for Occupational Safety and Health (NIOSH)
    "Poor mental health has a significant negative impact on the US economy, costing $193.2 billion annually, and increasing the risk of suicide. There are more than ten million construction workers in the United States, and prior research has shown that their mental health is often neglected, making them more susceptible to substance misuse, drug over ...
  • Effect of EpithelialSpecific MyD88 Signaling Pathway on Airway Inflammatory Response to Organic Dust Exposure
    Effect of Epithelial-Specific MyD88 Signaling Pathway on Airway Inflammatory Response to Organic Dust Exposure
    Dickinson J ;
    Evans SE
    2023/12/31 | National Institute for Occupational Safety and Health (NIOSH)
    The Toll-like receptor (TLR) adaptor protein MyD88 is integral to airway inflammatory response to microbial-enriched organic dust extract (ODE) exposures. ODE-induced airway neutrophil influx and release of pro-inflammatory cytokines was essentially abrogated in global MyD88-deficient mice, yet these mice demonstrate an increase in airway epithelia ...
