    PSA time to nadir as a prognostic factor of first-line docetaxel treatment in castration-resistant prostate cancer: evidence from patients in Northwestern China.
    Asian J Androl 2017 Sep 12. Epub 2017 Sep 12.
    Department of Urology, The First Affiliated Hospital of Xi'an Jiaotong University, Xi'an 710061, China.
    Docetaxel-based chemotherapy remains the first-line treatment for patients with metastatic castration-resistant prostate cancer (mCRPC) in China; however, the prognostic factors associated with effects in these patients are still controversial. In this study, we retrospectively reviewed the data from 71 eligible Chinese patients who received docetaxel chemotherapy from 2009 to 2016 in our hospital and experienced a reduction of prostate-specific antigen (PSA) level ≥50% during the treatment and investigated the potential role of time to nadir (TTN) of PSA. TTN was defined as the time from start of chemotherapy to the nadir of PSA level during the treatment. Read More

    Division of Urology, Department of Surgery, University of Utah, Salt Lake City, Utah 84132, USA.
    Proton-pump inhibitors (PPIs) are among the most widely used drugs worldwide. PPI use has recently been linked to adverse changes in semen quality in healthy men; however, the effects of PPI use on semen parameters remain largely unknown specifically in cases with male factor infertility. We examined whether PPI use was associated with detrimental effects on semen parameters in a large population of subfertile men. Read More

    Andrographolide sensitizes prostate cancer cells to TRAIL-induced apoptosis.
    Asian J Androl 2017 Sep 1. Epub 2017 Sep 1.
    Department of Urology, The First Affiliated Hospital of Xi'an Jiaotong University, Xi'an 710061, China.
    Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising agent for anticancer therapy. The identification of small molecules that can establish the sensitivity of prostate cancer (PCa) cells to TRAIL-induced apoptosis is crucial for the targeted treatment of PCa. PC3, DU145, JAC-1, TsuPr1, and LNCaP cells were treated with Andrographolide (Andro) and TRAIL, and the apoptosis was measured using the Annexin V/PI double staining method. Read More

    Antiarrhythmic drug usage and prostate cancer: a population-based cohort study.
    Asian J Androl 2017 Aug 29. Epub 2017 Aug 29.
    Department of Urology, National Taiwan University Hospital, National Taiwan University College of Medicine, Taipei 110, Taiwan, China.
    Even though the relationship between antiarrhythmic drug usage and subsequent prostate cancer (PCa) risk has recently been highlighted, relevant findings in the previous literature are still inconsistent. In addition, very few studies have attempted to investigate the association between sodium channel blockers or potassium channel blockers for arrhythmia and the subsequent PCa risk. Therefore, this cohort study aimed to find the relationship between antiarrhythmic drug usage and the subsequent PCa risk using a population-based dataset. Read More

    Department of Urology, University Hospital Tuebingen, Hoppe-Seyler-Straße 3, Tuebingen 72076, Germany.
    Circulating tumor cells (CTC) have become an important biomarker in patients with advanced prostate cancer. CTC count has been demonstrated to be a prognostic factor for overall survival in patients with metastatic castration-resistant prostate cancer (mCRPC). In localized prostate cancer, a clear correlation between CTC counts and clinicopathological risk parameters and outcome has not been observed. Read More

    Testosterone treatment and cardiovascular events in prescription database studies.
    Asian J Androl 2017 Aug 11. Epub 2017 Aug 11.
    Department of Psychiatry and Behavioral Sciences, University of Washington School of Medicine, VA Puget Sound Health Care System, 1660 South Columbian Way Seattle, WA 98108, USA.
    Over the past decade, there has been a substantial increase in the number of men who are treated with testosterone. Despite this increase in the use of testosterone, the risks of adverse cardiovascular events are unclear as meta-analyses have reported conflicting findings and no clinical studies have been large enough or long enough to adequately assess for cardiovascular risks. The goal of this paper is to review large prescription database studies of testosterone treatment and adverse cardiovascular events and mortality with the aim of providing some guidance for clinicians and researchers in this controversial area.

    Trials of testosterone replacement reporting cardiovascular adverse events.
    Asian J Androl 2017 Aug 4. Epub 2017 Aug 4.
    Research Program in Men's Health: Aging and Metabolism, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115, USA.
    The numbers of testosterone prescriptions written have increased several-fold worldwide, but the incidence of pathological hypogonadism due to hypothalamic, pituitary, and testicular disease has remained unchanged. Most of these prescriptions are being dispensed to middle-aged and older men who have experienced age-related decline in serum testosterone levels; a subset of the population in which benefits of testosterone replacement is at best, modest. Recently, some randomized controlled trials have reported increased cardiovascular events in men (mainly older men and those with prevalent cardiovascular disease) with testosterone use, and a few recent meta-analyses have confirmed these findings.

    Section of Pathological Anatomy, Polytechnic University of the Marche Region, School of Medicine, United Hospitals, Ancona, Italy.
    The Gleason grading system for prostate cancer (PCa) was developed in the 1960s by DF Gleason. Due to changes in PCa detection and treatment, the application of the Gleason grading system has changed considerably in pathology routine practice. Two consensus conferences were held in 2005 and in 2014 to update PCa Gleason grading. Read More

    The role of the serum testosterone levels as a predictor of prostate cancer in patients with atypical small acinar proliferation at the first prostate biopsy.
    Asian J Androl 2017 Jul 11. Epub 2017 Jul 11.
    Department of Urology, Polytechnic University of Marche, Ancona 60126, Italy.
    The current literature does not support the usefulness of clinical markers on predicting which patients with atypical small acinar proliferation (ASAP) are more likely to progress to prostate cancer (PCa). Androgens have long been considered to be the potential risk factors for PCa. However, the role of testosterone is controversial. Read More

    Sperm DNA damage has a negative effect on early embryonic development following in vitro fertilization.

    Reproductive Medicine Center, Family Planning Research Institute of Guangdong Province, Guangzhou 510060, China.
    Sperm DNA damage is recognized as an important biomarker of male infertility. To investigate this, sperm DNA damage was assessed by the sperm chromatin dispersion (SCD) test in semen and motile spermatozoa harvested by combined density gradient centrifugation (DGC) and swim-up in 161 couples undergoing in vitro fertilization (IVF). Semen analysis and sperm DNA damage results were compared between couples who did or did not achieve pregnancy. Read More

    The role of peroxisome proliferator-activated receptor gamma in prostate cancer.
    Asian J Androl 2017 Jun 9. Epub 2017 Jun 9.
    Department of Medical Oncology, City of Hope National Medical Center, Duarte, CA91010, USA.
    Despite great progress in the detection and treatment of prostate cancer, this disease remains an incredible health and economic burden. Although androgen receptor (AR) signaling plays a key role in the development and progression of prostate cancer, aberrations in other molecular pathways also contribute to the disease, making it essential to identify and develop drugs against novel targets, both for the prevention and treatment of prostate cancer. One promising target is the peroxisome proliferator-activated receptor gamma (PPARγ) protein. Read More

    Association between diacylglycerol kinase kappa variants and hypospadias susceptibility in a Han Chinese population.
    Asian J Androl 2017 Jun 9. Epub 2017 Jun 9.
    Department of Urology, Shanghai Children's Hospital, Shanghai Jiao Tong University, Shanghai 200062, China.
    Previous genome-wide association studies have identified variants in the diacylglycerol kinase kappa (DGKK) gene associated with hypospadias in populations of European descent. However, no variants of DGKK were confirmed to be associated with hypospadias in a recent Han Chinese study population, likely due to the limited number of single-nucleotide polymorphisms (SNPs) included in the analysis. In this study, we aimed to address the inconsistent results and evaluate the association between DGKK and hypospadias in the Han Chinese population through a more comprehensive analysis of DGKK variants.
