Prostate cancer is a common cancer among males in the US, but little is known about its risk factors, including trace elements. The primary aim of this study was to examine prostate cancer and its association with arsenic and selenium in toenails. We conducted a small, nested case-control study of men residing in Iowa within the Agricultural Health Study cohort, where we also collected toenail samples to test for arsenic and other trace elements.

- A narrative review was conducted to assess how race and socioeconomic status impact penile cancer rates, revealing higher incidence in underdeveloped regions.
- HPV-related tumors are more common globally in areas with high rates of HPV and HIV, with socioeconomic factors worsening these disparities.
- In the U.S., racial disparities were evident, particularly for black men, highlighting the need for targeted education and interventions like HPV vaccination to reduce penile cancer burdens in at-risk populations.
Article Synopsis
- A recent study investigated how MRI-visible perivascular spaces (MV-PVS) develop in adolescents and young adults, focusing on their volume and how factors like age, sex, and BMI affect these changes.
- The study analyzed data from 783 healthy participants aged 12-21 over five years, revealing that males consistently had larger MV-PVS volumes than females.
- It was found that for females, increases in body mass index (BMI) were linked to increases in MV-PVS volume, suggesting a relationship between sex, BMI, and MV-PVS that could inform future research.
Article Synopsis
- New technologies are being developed that can detect tiny pieces of tumor DNA in blood, which could help doctors make better treatment decisions for cancer patients.
- A new test called FoundationOne®Tracker can track changes in this tumor DNA without needing extra samples from patients, which makes it easier and faster to get results.
- The test is really accurate, with 99.6% specificity and over 97% sensitivity, meaning it works well to find the tumor DNA in blood samples.
