  • The Association Between Ambient PM25 and Low Birth Weight in California
    The Association Between Ambient PM2.5 and Low Birth Weight in California
    Balmes JR ;
    Costello S
    2022/10/19 | National Institute for Occupational Safety and Health (NIOSH)
    Previous studies have shown associations between air pollutants and low birth weight. However, few studies assess whether poverty and race/ethnicity are effect modifiers for this relationship. We used publicly available data on 7785 California census tracts from the California Communities Environmental Health Screening Tool (CalEnviroScreen). Multi ...

    Rader EP
    2022/10/18 | National Institute for Occupational Safety and Health (NIOSH)
    Rodent studies investigating long-term effects following termination of hypertrophy-inducing loading have predominantly involved exposures such as synergist ablation and weighted wheel running or ladder climbing. This research yielded a spectrum of results regarding the extent of detraining in terms of muscle mass and myonuclei number. The studies ...

  • Genomic Basis for Individual Differences in Susceptibility to the Neurotoxic Effects of Diesel Exhaust
    Genomic Basis for Individual Differences in Susceptibility to the Neurotoxic Effects of Diesel Exhaust
    Ashbrook DG ;
    Cormier SA
    2022/10/18 | National Institute for Occupational Safety and Health (NIOSH)
    Air pollution is a known environmental health hazard. A major source of air pollution includes diesel exhaust (DE). Initially, research on DE focused on respiratory morbidities; however, more recently, exposures to DE have been associated with neurological developmental disorders and neurodegeneration. In this study, we investigated the effects of ...

  • A Qualitative Characterization of MesoActivity Factors to Estimate Soil Exposure for Agricultural Workers
    A Qualitative Characterization of Meso-Activity Factors to Estimate Soil Exposure for Agricultural Workers
    Agnew, Jacqueline ;
    Burke, Thomas A.
    2022/10/17 | National Institute for Occupational Safety and Health (NIOSH)
    Background: Agricultural workers' exposure to soil contaminants is not well characterized. Activity pattern data are a useful exposure assessment tool to estimate extent of soil contact, though existing data do not sufficiently capture the range and magnitude of soil contact in the agricultural context. Objective: We introduce meso-activity, or spe ...
  • Revisiting Rockfall Catch Bench Design Criteria Initial Rockfall Testing Results from the Golden Chest Mine ID
    Revisiting Rockfall Catch Bench Design Criteria: Initial Rockfall Testing Results from the Golden Chest Mine, ID
    Armstrong J ;
    Bourgeois J
    2022/10/17 | Mining Publications
    Rockfall in open pit mines presents a continuous hazard to mine workers and is typically mitigated by designing catch benches to empirically determined widths. Industry geotechnical engineers have expressed interest in revisiting traditional bench design guidelines to better balance rockfall catchment performance and pit economics, or at least to q ...

  • Development of a Comprehensive Slope Failure Evaluation Database for Open Pit Mines
    Development of a Comprehensive Slope Failure Evaluation Database for Open Pit Mines
    Bourgeois J ;
    Sbai S
    2022/10/17 | Mining Publications
    Predicting slope behaviour over time is a crucial geotechnical engineering task for open pit mines. Information gathered from monitoring practices is used to anticipate the potential failure of a slope mass, giving mine sites the ability to safely operate with minimal interruption. Correct monitoring procedures and an understanding of failure mecha ...

  • A Test of Social Cognitive Theory to Increase Hearing Protection Use in Swine Buildings
    A Test of Social Cognitive Theory to Increase Hearing Protection Use in Swine Buildings
    Campo S ;
    Janssen B
    2022/10/17 | National Institute for Occupational Safety and Health (NIOSH)
    Farming ranks among the top occupations for which workers are at risk for noise-induced hearing loss (NIHL), an irreversible yet preventable condition. Hearing Protection Devices (HPDs) (i.e., earmuffs and ear plugs) are effective at preventing exposure to noise; however, few farmers report consistent use. The purpose of this study was to test an i ...

  • PostEndotoxin ExposureInduced Lung Inflammation and Resolution Consequences Beneficially Impacted by LungDelivered IL10 Therapy
    Post-Endotoxin Exposure-Induced Lung Inflammation and Resolution Consequences Beneficially Impacted by Lung-Delivered IL-10 Therapy
    Gaurav R ;
    Gleason A
    2022/10/15 | National Institute for Occupational Safety and Health (NIOSH)
    Although lung diseases typically result from long-term exposures, even a robust, one-time exposure can result in long-lasting consequences. Endotoxin is a ubiquitous environmental/occupational inflammatory agent often used to model airway inflammation. Using a murine model, the return to lung homeostasis following high dose inhalant lipopolysacchar ...

    2022/10/14 | Weekly Report: Morbidity and Mortality Weekly Report (MMWR)
    During June-November 2021, multiple cyanobacteria harmful algal blooms (HABs) occurred in Clear Lake, the largest freshwater body of water located entirely within the state of California. During this period, measured chemical concentrations of microcystins (a class of cyanotoxins produced by cyanobacteria) in the water of the Lower and Oaks arms of ...

    Retrospective Analysis of Ulnar Collateral Ligament Reconstructions in Major League Baseball Pitchers: A Comparison of the “Tall and Fall” Versus “Drop and Drive” Pitching Styles
    Baker BA ;
    Beaudry AG
    2022/10/12 | National Institute for Occupational Safety and Health (NIOSH)
    Background: Previous pilot research has investigated differences in elbow valgus torque between the "tall and fall" (TF) and "drop and drive" (DD) pitching styles. Whether one of these pitching styles is associated with a greater rate of ulnar collateral ligament reconstruction (UCLR) is currently unknown. Purpose: To determine the proportion of Ma ...

    Rechargeable Antimicrobial Textiles to Reduce Occupational Risk of Healthcare Personnel
    Goodyear N ;
    Sun Y
    2022/10/12 | Grant Final Reports
    Healthcare personnel (HCP) have a high occupational burden of exposures to infectious agents. Service textiles are high-touch surfaces in the healthcare environment and they play an important role in the acquisition and transmission of pathogenic microorganisms. Extensive studies have shown that in general practice, "clean" healthcare service texti ...
  • Community participatory approaches to Total Worker Health improving structural and social determinants of health through communityled interventions
    Community participatory approaches to Total Worker Health®: improving structural and social determinants of health through community-led interventions.
    Gulliot-Wright S
    2022/10/12 | National Institute for Occupational Safety and Health (NIOSH)
    Community-led interventions that address structural and social determinants of health are lacking among (im)migrant workers, especially seafood workers. This lack of medical attention is especially alarming given their high rate of injury and death. The future of work equity demands a research agenda that looks at occupational health holistically, ...

    Axtell C ;
    Nielsen K
    2022/10/11 | National Institute for Occupational Safety and Health (NIOSH)
    Purpose: Realist evaluation seeks to answer the question of "what works for whom in which circumstances?" through developing and testing middle range theories (MRTs). MRTs are programme theories that outline how certain mechanisms of an intervention work in a specific context to bring about certain outcomes. In this paper, the authors tested an ini ...

  • What Is a Normal Blood Lead Level
    What Is a Normal Blood Lead Level?
    Michigan State University. College of Human Medicine
    2022/10/10 | National Institute for Occupational Safety and Health (NIOSH)
    With the decrease in exposure to lead to the general public after its ban from residential paint in 1978, lead solder in tin cans for food in 1995, and gasoline in 1996 except for fuel in aircraft, racing cars, farm equipment, and marine engines, the average level of lead in the general population has decreased. In 2021, the Centers for Disease Con ...
