PSA screening for prostate cancer
Summary Screening of prostate cancer with prostate-specific antigen (PSA) is a highly controversial issue. One part of the controversy is due to the confusion between population screening and early diagnosis, another derives from problems related to the quality of existing screening studies, the results of radical curative treatment for low grade tumors and the complications resulting from treatments that affect the patient ’ s quality of life. Our review aimed to critically analyze the current recommendations for PSA testing, based on new data provided by the re-evaluation of the ongoing studies and the updated USPS...

Association between physical activity and vitamin D: A narrative literature review
Summary This narrative review of the medical literature assessed whether outdoor and indoor physical activity would increase the plasma levels of vitamin D.
