    Flint MS ;
    Morgan J
    2000/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    The interaction between stress-induced activation of the hypothalamic-pituitary-adrenal axis (HP AA) and the immune system is well established. Several researchers have localized many components of the HPAA in the skin, including corticotropin releasing hormone receptor, proopiomelanocortin (POMC), adrenocorticotropic hormone and alpha-melanocortic ...

    Occupational Injuries and the Older Worker: Challenges in Research, Policy and Practice
    Benjamin KL ;
    Pransky-G
    2000/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    Little is known about the outcomes of occupational injuries and illnesses in older workers. While employers, benefits managers and policy makers are increasingly aware of the present and future growth of this segment of the workforce, they have not yet focused upon this issue. They may be influenced by the common research finding that older workers ...

    Effects of Omitting a Covariate in Poisson Models When the Data Are Balanced
    Deddens JA ;
    Petersen, Martin R.
    2000/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    The authors show that for balanced data, the estimate of effects of interest and of their standard errors are unaffected when a covariate is removed from a multiplicative Poisson model. As they point out, this is not verified in the analogous linear model, nor in the logistic model. In the first case, only the estimated coefficients remain the same ...

    2000/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    It is important to understand a medical testis performance characteristics, so that it can be used appropriately. Performance characteristics of tests for antibodies specific to low-molecular-weight (LMW) agents in predicting asthma caused by these agents differ in the study population. In general, currently published data supporting the use of tes ...

    Too Hot to Handle: An Unusual Exposure of HDI in Specialty Painters
    Ducatman AM ;
    Franklin E
    2000/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    Hexamethylene Diisocyanate (HDI) is a color stable aliphatic isocyanate that is used in specialty paints as a hardener. Due to the lower vapor pressure of its commercial biuret form, it is considered a relatively "safe" isocyanate from an exposure standpoint. This case series reports on an unusual toxic exposure to HDI. Between November 1993 and Ma ...
