  • The Alcohol Exposome
    The Alcohol Exposome
    Sabet NH ;
    Wyatt TA
    2025/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Alcohol misuse is long established as a contributor to the pathophysiology of the lung. The intersection of multi-organ responses to alcohol-mediated tissue injury likely contributes to the modulation of lung in response to injury. Indeed, the negative impact of alcohol on susceptibility to infection and on lung barrier function is now well documen ...

    Sleep Disturbances Across 2 Weeks Predict Future Mental Healthcare Utilization
    Kotov R ;
    Luft B
    2025/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Study Objectives: Insufficient sleep costs the US economy over $411 billion per year. However, most studies investigating the economic costs of sleep rely on one-time measures of sleep, which may be prone to recall bias and cannot capture variability in sleep. To address these gaps, we examined how sleep metrics captured from daily sleep diaries pr ...
