Background: Pesticide exposure may contribute to cognitive decline, but empirical evidence is limited. We examined high pesticide exposure events (HPEE) in relation to subjective cognitive decline among farmers in the Pesticide and Sense of Smell Study (PASS), a sub-cohort of the Agricultural Health Study (AHS).

Method: This analysis included 2365 predominantly white male farmers from Iowa and North Carolina (aged 70±10 years) who enrolled in AHS from 1993-1997 and participated in PASS in 2020-2021.

Estimated exposure to endotoxin and circulating immunological markers among male farmers in the Biomarkers of Exposure and Effect in Agriculture study.

Background: Occupational exposure to endotoxin has been associated with reduced lung cancer risk. The mechanisms underlying this association are unclear, though immunological alterations likely play a role. Farmers who perform certain tasks (eg, raising hogs) can be highly exposed to endotoxin.

Volatile hydrocarbon exposures and immune-related illnesses among Deepwater Horizon oil spill workers.

Background: Despite evidence from experimental studies linking some petroleum hydrocarbons to markers of immune suppression, limited epidemiologic research exists on this topic.

Objective: The aim of this cross-sectional study was to examine associations of oil spill related chemicals (benzene, toluene, ethylbenzene, xylene, and n-hexane (BTEX-H)) and total hydrocarbons (THC) with immune-related illnesses as indicators of potential immune suppression.

Methods: Subjects comprised 8601 Deepwater Horizon (DWH) oil spill clean-up and response workers who participated in a home visit (1-3 years after the DWH spill) in the Gulf Long-term Follow-up (GuLF) Study.

Posterior Vault Distraction Osteogenesis for Craniosynostosis-Surgical Outcomes Over 12 Years.

Introduction: Posterior vault distraction osteogenesis (PVDO) allows significant increase in intracranial volume but is associated with complications including cerebrospinal fluid (CSF) leaks, infection and device failure. The authors outline their outcomes over 12 years and the impact of PVDO on pre-existing Chiari malformation type 1 (CM).

Method: Retrospective review of all PVDOs in our unit over a period of 12 years from 2011 to 2023.

Influence of occupational stress on breast cancer incidence in the Women's Health Initiative.

Objective: Psychological stress has long been posited as a potential risk factor for breast cancer. We aimed to examine the relationship between occupational stress and the incidence of invasive breast cancer among postmenopausal women from the Women's Health Initiative Observational Study.

Method: Occupational stress was characterized through linkage of Standard Occupational Classification codes for participants' jobs to the Occupational Information Network.
