Associations of Prostate Tumor Immune Landscape with Vigorous Physical Activity and Prostate Cancer Progression.

Background: Vigorous physical activity has been associated with lower risk of fatal prostate cancer. However, mechanisms contributing to this relationship are not understood.

Methods: We studied 117 men with prostate cancer in the University of North Carolina Cancer Survivorship Cohort (UNC CSC) who underwent radical prostatectomy and 101 radiation-treated patients with prostate cancer in FASTMAN.

Vaccinations and childhood type 1 diabetes mellitus: a meta-analysis of observational studies.

Aims/hypothesis: The aim of this study was to investigate the association between routine vaccinations and the risk of childhood type 1 diabetes mellitus by systematically reviewing the published literature and performing meta-analyses where possible.

Methods: A comprehensive literature search was performed of MEDLINE and EMBASE to identify all studies that compared vaccination rates in children who subsequently developed type 1 diabetes mellitus and in control children. ORs and 95% CIs were obtained from published reports or derived from individual patient data and then combined using a random effects meta-analysis.
