The purpose of this study was to determine the relationship between insulin resistance, obesity and serum prostate-specific antigen (PSA) levels in healthy men with serum PSA level below 4 ng mL(-1). The men included in the study cohort were 11 827 healthy male employees of the Korea Hydro and Nuclear Power Co., LTD who had undergone medical checkups including fasting glucose, fasting insulin a...

background: the normal prostate-specific antigen (psa) level in patients with urethral catheterization is a controversy. we designed this study to investigate the effect of nontraumatic urethral catheterization without urinary retention on serum psa. materials and methods: seventy patients scheduled for urethral catheterization before elective surgeries were randomly selected and included in th...

The main objective of the present study was to determine the potential of n-3 and n-6 fatty acids or coenzyme Q10 (CoQ10) to alter serum prostate-specific antigen (PSA) levels in normal healthy men. A total of 504 healthy men with serum PSA level ≤ 2·5 ng/ml were recruited into the study. Serum PSA values were not segregated by decade of age. Participants were randomly assigned to a daily dieta...

This study is to assess the potential factors that could affect the serum prostate-specific antigen (PSA) level in healthy younger men. We evaluated the associations of age, body mass index (BMI) and serum lipid profile with serum PSA level in 6774 Chinese men (aged 20-49 years) who received a routine health examination. Eligible men were classified into 10-year age groups. BMI was categorized ...

OBJECTIVE The aims of this study were to examine if serum prostate-specific antigen (PSA) levels are lower in men with type 2 diabetes compared with those in healthy men and to investigate what factors may be associated with serum PSA levels in men with type 2 diabetes. RESEARCH DESIGN AND METHODS We compared the serum PSA levels in 224 diabetic men with those in 1,293 healthy men and investi...

OBJECTIVES This study measures serum prostate-specific antigen (PSA) levels in tire-manufacturing workers, and attempts to find occupational or non-occupational factors that related to their PSA levels. METHODS A total of 1,958 healthy male workers (1,699 were production workers and 259 were office workers) took PSA measurement for analysis. RESULTS After adjusting for age, body mass index,...

The objective of this study was to determine whether there is any beneficial effect of oral 13-cis-retinoic acid (isotretinoin) on prostate cancer, using serum prostate-specific antigen (PSA) levels as a surrogate end point in patients with a rising serum PSA after radical prostatectomy. In the first phase, the effect of the drug on the serum PSA level was tested in 14 control patients with nor...

background: breast cancer is the most common cancer in women. prostate‑specifc antigen  (psa) is a marker of prostate gland malignancy, which has been considered in cases with breast cancer in recent years. the goal of this study was to determine total and free psa levels in cases with malignant and benign breast lesions. methods:   in  this case–control study, ninety women with histological pr...

To clarify the recent trends in prostate-specific antigen (PSA) distribution in men in Japan, we analyzed the PSA distributions of men undergoing PSA-based population screening. We summarized the annual individual data of PSA-based population screening in Kanazawa, Japan, from 2000 to 2011, and analyzed baseline serum PSA values of the participants at the first population screening. Serum PSA d...
