MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by CTE?
Response: CTE, or chronic traumatic encephalopathy, is a progressive neurodegenerative disorder that is linked to prior exposure to repetitive traumatic brain injuries. CTE pathology, characterized by a distinct deposition pattern of the protein ‘tau’, is most often observed in the brains former contact sport athletes and military veterans. The public health impacts of this disorder are largely unknown, as this disease is often studied in individuals which advanced levels of exposure, particularly professional American football player.
This study aimed to understand what the presence of this disorder might be in the general population by studying athletes and non-athletes, a number of different sports, different levels of participation, and both males and females.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: An excess incidence of prostate cancer has been identified among World Trade Center responders. We wanted to study if this excess was associated with exposure to WTC dust
The results suggest that respiratory exposure to WTC dust can induce inflammatory and immune responses in prostate tissue. Chronic inflammation could facilitate prostate cancer development
Taken together, our results suggest that World Trade Center prostate cancer cases have a distinct gene expression pattern that may be the result of exposure to specific carcinogens during the WTC attacks. WTC dust-exposed rat prostate displayed unique changes in gene expression and immune cell infiltrates after acute dust exposure, suggesting that the effect of exposure may be measured locally in target organs such as prostate. In addition, some of the genes overexpressed in rat normal prostates as a consequence of exposure are also overexpressed in human prostate cancer tissues, suggesting a link between exposure, local immune dysregulation, and prostate cancer development
