    2023/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Nitric oxide can interact with a wide range of proteins including many that are involved in metabolism. In this review we have summarized the effects of NO on glycolysis, fatty acid metabolism, the TCA cycle, and oxidative phosphorylation with reference to skeletal muscle. Low to moderate NO concentrations upregulate glucose and fatty acid oxidatio ...

    2023/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Wastewater surveillance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be useful for monitoring population-wide coronavirus disease 2019 (COVID-19) infections, especially given asymptomatic infections and limitations in diagnostic testing. We aimed to detect SARS-CoV-2 RNA in wastewater and compare viral concentrations to COVID ...
  • Investigation of a RiverTunnel Effect on PM25 Concentrations in New York City Subway Stations
    Investigation of a River-Tunnel Effect on PM2.5 Concentrations in New York City Subway Stations
    Gordon T ;
    Huynh T
    2023/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    It is well-documented that subway stations exhibit high fine particulate matter (PM2.5) concentrations. Little is known about the potential of river-tunnels to increase PM2.5 concentrations in subways. We hypothesized a "river-tunnel" effect exists: Stations adjacent to poorly ventilated tunnels that travel beneath rivers exhibit higher PM2.5 conce ...
  • Workplace Violence Prevalence and Reporting in Home Health Care A Cross Sectional Survey
    Workplace Violence Prevalence and Reporting in Home Health Care: A Cross Sectional Survey
    Davis, Kermit G. ;
    Gillespie GL
    2023/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Workplace violence (WV) is a significant occupational hazard for home health care workers (HHCWs). HHCWs are frequently exposed to Type II (customer/client) WV incidents but minimal evidence exists about exposure to Type III (coworker) WV and exposure to Type IV (personal relationship) WV is unknown. Furthermore, exposure to WV incidents is often u ...

    Gambatese JA ;
    Karakhan AA
    2023/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Due to the dynamic and recurring nature of construction operations, employee turnover rates remain relatively high. This high employee turnover rate presents challenges to the industry, the economy, and society as a whole. In addition, this high turnover rate leads to a significant shortage of skilled laborers given the reduced interest of new gene ...

    2023/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Bladder cancer is the sixth most common cancer in the United States. Night shift work has previously been linked with cancer risk. Whether there is an association between rotating night shift work and bladder cancer in women has not been studied previously. Eligible participants in the Nurses' Health Study (NHS, n = 82,147, 1988-2016) and Nurses' H ...
  • Investigating Gripping Force During Lifting Tasks Using a Pressure Sensing Glove System
    Investigating Gripping Force During Lifting Tasks Using a Pressure Sensing Glove System

    Yu D
    2023/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Lifting tasks remain one of the leading causes of musculoskeletal disorders (MSDs), primarily in the low back region. Lifting analysis tools are, therefore, designed for assessing the risk of low back pain. Shoulder musculoskeletal problems have emerged as common MSDs associated with manual handling tasks. It is hypothesized that gripping force is ...

    2023/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Fifty-one percent of construction workers are exposed to hazardous noise that can cause permanent noise induced hearing loss (NIHL), and 52% do not wear a hearing protection device (HPD). Hearing loss could be reduced more effectively with more accurate measurements of noise exposure. The common occupational noise exposure measurement devices are s ...

    2023/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Many respiratory diseases, including COVID-19, can be spread by aerosols expelled by infected people when they cough, talk, sing, or exhale. Exposure to these aerosols indoors can be reduced by portable air filtration units (air cleaners). Homemade or Do-It-Yourself (DIY) air filtration units are a popular alternative to commercially produced devic ...

    2023/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Purpose of review: Upper airway nitric oxide (NO) is physiologically important in airway regulation and defense, and can be modulated by various airway inflammatory conditions, including allergic rhinitis and chronic rhinosinusitis - with and without polyposis. Paranasal sinuses serve as a NO 'reservoir', with concentrations typically exceeding tho ...
  • Exposure to the Antimicrobial Chemical Triclosan Disrupts Keratinocyte Function and Skin Integrity in a Model of Reconstructed Human Epidermis (Dataset)
    National Institute for Occupational Safety and Health
    2023/01/31 | National Institute for Occupational Safety and Health (NIOSH)
    Triclosan is an antimicrobial chemical incorporated into products that are applied to the skin of healthcare workers. Exposure to triclosan has previously been shown to be immunomodulatory and associated with allergic disease. Additionally, we have shown that exposure to triclosan dermally activates the NLRP3 inflammasome and disrupts the skin barr ...

    2023/01/31 | National Institute for Occupational Safety and Health (NIOSH)
    Dust is an inherent byproduct of mining activities that raises notable health and safety concerns. Cumulative inhalation of respirable coal mine dust (RCMD) and respirable crystalline silica (RCS) can lead to obstructive lung diseases. Despite considerable efforts to reduce dust exposure by decreasing the permissible exposure limits (PEL) and impro ...
  • Β-Defensin-1 Regulates Influenza Virus Infection in Human Bronchial Epithelial Cells Through the STAT3 Signaling Pathway (Dataset)
    National Institute for Occupational Safety and Health
    2023/01/30 | National Institute for Occupational Safety and Health (NIOSH)
    Understanding the host response to influenza A virus (IAV) infection is vital for developing intervention strategies. The primary barriers for invading respiratory pathogens are the airway epithelial cells of the respiratory tract and antimicrobial peptides produced by these cells. The antimicrobial peptide, ß-defensin-1, has antiviral activity aga ...

    Hood S
    2023/01/30 | National Institute for Occupational Safety and Health (NIOSH)
    After above-knee amputation, the missing biological knee and ankle are commonly replaced with a passive prosthesis, which cannot provide net-positive energy to assist the user. During activities such as sit-to-stand, above-knee amputees must compensate for this lack of power using their upper body, intact limb, and residual limb, resulting in slowe ...
