    2023/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    Recent technological developments in remote sensing and image analysis and their introduction into the mining industry have opened the door for updating risk analysis techniques. The R&D team of the Mining Automation Lab of the University of Nevada-Reno develops UAV-based photogrammetry and image analysis technologies to address the geotechnical ri ...
  • Associations Between Obstructive Sleep Apnea and COVID19 Infection and Hospitalization Among US Adults
    Associations Between Obstructive Sleep Apnea and COVID-19 Infection and Hospitalization Among US Adults
    Barger LK ;
    Booker LA
    2023/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    STUDY OBJECTIVES: Medical comorbidities increase the risk of severe COVID-19 infection. In some studies, obstructive sleep apnea (OSA) has been identified as a comorbid condition that is associated with an increased prevalence of COVID-19 infection and hospitalization, but few have investigated this association in a general population. This study a ...
  • How Client Death Impacts Home Care Aides Workforce Outcomes An Exploratory Analysis of Return to Work and Job Retention
    How Client Death Impacts Home Care Aides’ Workforce Outcomes: An Exploratory Analysis of Return to Work and Job Retention
    Baron, Sherry L. ;
    Beato L
    2023/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    Home health aides face a range of stressors that may result in departing the workforce. One stressor that has emerged in multiple qualitative studies as potentially influencing retention is client death. Using 2019 data from a single agency in New York City employing approximately 1700 aides, we used logistic and linear regression to explore case a ...

    Supporting the Resilience and Mental Health of Missouri Healthcare Workers Through COVID-19 and Beyond: The Gateway2Wellness Program
    Colvin R ;
    Douglas C
    2023/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    The COVID-19 pandemic is over, but US healthcare workers (HCWs) continue to report high levels of work-related exhaustion and burnout but are unlikely to seek help. Digital tools offer a scalable solution. Between February and June 2022, we surveyed Missouri hospital administrators to assess HCW mental health and identify related evidence-based or ...
  • Understanding the Influence of Atomizing Power on Electronic Cigarette Aerosol Size and Inhalation Dose Estimation
    Understanding the Influence of Atomizing Power on Electronic Cigarette Aerosol Size and Inhalation Dose Estimation
    Han I ;
    Lee J
    2023/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    Although many studies have estimated the inhalation dose of aerosols emitted from electronic cigarettes (e-cigs), the association between the atomizing power and inhalation dose of e-cig aerosols has not been fully examined. The aim of this study was to determine the mass and inhalation doses of e-cig aerosols and their association with the atomizi ...

    Is It Time to Revisit OSHA Requirements/Guidance on CPR in the Workplace?
    Heaton K
    2023/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    On January 2, 2023, spectators and horrified TV viewers witnessed a workplace cardiac arrest when Buffalo Bills safety Damar Hamlin collapsed on the football field. On any given NFL gameday, there are at least 27 medical personnel, including paramedics and an "airway physician"-anesthesiologist and/or emergency medicine physician available on the f ...
  • Sharps Injuries Among Medical Trainees and Attending Physicians
    Sharps Injuries Among Medical Trainees and Attending Physicians
    Kasteler SD ;
    Laramie AK
    2023/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    Purpose: Sharps injuries are a particularly concerning occupational hazard faced by physicians and are largely preventable. This study compared the proportion and rate of sharps injuries among medical trainees with those among attending physicians by sharps injury characteristics. Method: The authors used data reported to the Massachusetts Sharps I ...

  • Numerical Investigation of Powder Aerosolization in a Mining Rock Dust Dispersion Chamber
    Numerical Investigation of Powder Aerosolization in a Mining Rock Dust Dispersion Chamber
    Chen H ;
    Ghia U
    2023/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    We have conducted numerical simulations of dust dispersion within the NIOSH Rock Dust Dispersion Chamber. The apparatus consists of a low-speed background ventilation flow down a long box in which is placed a tray containing a rock dust powder. A nozzle upstream of the tray introduces a short pulse of a turbulent horizontal jet flow just above the ...

  • Purification and Characterization of a Serine Protease from Organic Dust and Elucidation of Its Inductive Effects on Lung Inflammatory Mediators
    Purification and Characterization of a Serine Protease from Organic Dust and Elucidation of Its Inductive Effects on Lung Inflammatory Mediators
    Boggaram V ;
    Keshava S
    2023/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    Organic dust inhalation is associated with the development of respiratory diseases. Serine protease activities in organic dusts were previously reported to contribute to the induction of lung inflammatory mediators however, the identities of the proteases and the mechanisms by which they induce inflammatory mediators are unknown. The goal of this s ...
  • Bone Lead Variability in Bone Repository Skeletal Samples Measured with Portable XRay Fluorescence
    Bone Lead Variability in Bone Repository Skeletal Samples Measured with Portable X-Ray Fluorescence
    Bartell SM ;
    Davis M
    2023/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    Bone lead serves as a better, more accessible biomarker to many communities experiencing chronic exposure to lead. A new method using low energy x-ray fluorescence in a handheld device (portable XRF) allows us to measure this chronic biomarker in only a few minutes. However, many unknowns remain about this biomarker measured using a new low energy ...
  • Modeling Brazilian Tensile Strength Tests on a Brittle Rock Using Deterministic SemiDeterministic and Voronoi Bonded Block Models
    Modeling Brazilian Tensile Strength Tests on a Brittle Rock Using Deterministic, Semi-Deterministic, and Voronoi Bonded Block Models

  • Formation of Protein Adducts with HydroperoxyPE Electrophilic Cleavage Products During Ferroptosis
    Formation of Protein Adducts with Hydroperoxy-PE Electrophilic Cleavage Products During Ferroptosis
    Amoscato AA ;
    Anthonymuthu T
    2023/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    Ferroptosis is an iron dependent form of cell death, that is triggered by the discoordination of iron, lipids, and thiols. Its unique signature that distinguishes it from other forms of cell death is the formation and accumulation of lipid hydroperoxides, particularly oxidized forms of polyunsaturated phosphatidylethanolamines (PEs), which drives c ...

    2023/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    Silicosis is a preventable occupational lung disease caused by inhaled silica dust. Solutions to prevent silicosis ranging from engineering controls to respirator use have been validated for nearly a century, but many workers are still at-risk of this preventable disease. We characterized how the physical, social, and institutional environments con ...
