Abstract
BACKGROUND Advances in chromatography and mass spectrometry have allowed us to develop a novel technique for measuring intraprostatic hormone concentrations directly on prostate needle biopsies, rather than using traditional punch excision. This has significant clinical implications as intraprostatic dihydrotestosterone and testosterone levels could help monitor prostate growth, neoplasia and castration resistance. METHODS Patients undergoing radical cystoprostatectomy for bladder cancer were prospectively included. Each prostate specimen received one 90mg punch excision and six needle biopsies. Intraprostatic hormones were dosed through gas chromatography-mass spectrometry. RESULTS We included twenty patients, of which eleven were incidentally diagnosed with prostate cancer; four had ISUP 1 (20%) and seven had ISUP 2 (35%). The prostate biopsy technique was unable to obtain measures for testosterone, Delta-4-androsterone and androstenedione. Tissue concentrations of DHEA, DHT, E1 and E2 can be obtained with no significant difference from the reference established on a punch from a single biopsy core sample. CONCLUSIONS Our study demonstrates that intraprostatic concentrations of DHEA, DHT, E1 and E2 can be measured without significant difference from the reference established on a single punch excision. This finding opens the way to research on the interactions between endocrinology and prostate oncogenesis and particularly on the mechanisms of resistance to hormone therapies in vivo.

Abstract
Unconjugated sex steroids in human serum play a crucial role in physiological and pathological studies and are frequently considered as biomarkers in clinical diagnosis. Because of their low polarity, poor volatility, and low concentration, the rapid and highly sensitive analysis of sex steroids in real serum matrix by ambient mass spectrometry is still challenging. Here, Leidenfrost effect-assisted thermal desorption atmospheric pressure photoionization orbitrap mass spectrometry (LETD-APPI-MS) was developed and applied to quantify free sex steroids in human serum without derivatization and chromatography separation within a few minutes. The concentration of target analyte could be increased by approximately two orders during the LETD process. The limit of quantifications and detections of endogenous sex steroids in human serum were measured at the ppt level. In contrast with commonly used immunoassays in clinical laboratories, LETD-APPI-MS enables the accurate measurements of multiple free sex steroids without the interference of cross-reactions. The endogenous sex steroids of 38 female serums at four physiological stages during pregnancy were rapidly tested by LETD-APPI-MS, whose results were highly consistent with that using liquid chromatography-atmospheric pressure chemical ionization mass spectrometry (LC-APCI-MS), indicating LETD-APPI-MS has a strong clinical application potential in steroid analysis.

Abstract
BACKGROUND Although they are involved in the progression of PCa, the use of sex steroid hormones in urinary exosomes as biomarkers for PCa remains obscure. Here, the potential use of sex steroid hormones in urinary exosomes as biomarkers was investigated for the prediction of early-stage PCa to assist in clinical diagnosis. METHODS Two hundred and eighty-six participants were randomly recruited, 231 patients with PCa and 55 healthy controls. According to their Gleason scores (GSs), the patients with PCa were divided into two groups, mild PCa (GS6) (n=116) and severe (≥ GS7) group (n=115),. The concentrations of 8 sex steroid hormones in urinary exosomes were quantitated using liquid chromatography tandem mass spectrometry with atmospheric pressure chemical ionization (LC-APCI-MS/MS). RESULTS The results showed that the levels of 7 out of 8 sex steroids including dehydroepiandrosterone (DHEA), dehydroepiandrosteronesulfate (DHEAS), androstenedione (A4), testosterone (T), progesterone (P), dihydrotestosterone (DHT), and estrone (E1), but not estradiol (E2) in urinary exosomes, were not only distinguished the PCa patients from healthy controls, can also differentiate between patients with mild and severe PCa. Of the 8 selected urinary exosomal biomarkers, DHEA, DHEAS, T, and DHT were finally screened further to build the regression model, and the detection method of the 4 biomarkers-combined achieved an area under the ROC curve (AUC) of 0.854 and predictive accuracy of 78.2%. CONCLUSION Our data showed the use of exosomal sex steroids in urine could be as biomarkers for predicting PCa for the first time. This finding would supply a novel insight for PCa diagnosis.

Abstract
BACKGROUND AND OBJECTIVE Lower Urinary Tract Symptoms (LUTS) and Benign Prostatic Hyperplasia (BPH) are progressive ailments resulting from androgenic imbalances and aging that can lead to serious long term complications. Objective of this study was to determine the relationship between prostate-specific antigens and testosterone hormone levels in patients with BPH before transurethral surgery. MATERIALS AND METHODS This case control study was done on 112 serum samples collected from two secondary care centres in Khartoum, Sudan. Collected serum samples were analyzed by ELISA and fluorescence enzymes immunoassay to measure testosterone, total PSA level and free PSA levels, respectively. RESULTS Out of 112 patients, 56 BPH diagnosed patients were included in the study with mean age 67.10±7.90 years. Total PSA (T. PSA) levels were higher in patients (14.1±10.6 ng mL-1) than the control group (2.21±1.01 ng mL-1). Total 52% of patients had total PSA level in the gray zone (4-10 ng mL-1) and 33% had total PSA more than 10 ng mL-1. Testosterone levels were low in patients 3.97±2.84 ng mL-1 when compared to the control group 4.95±0.59 ng mL-1. CONCLUSION The present study revealed that, there was a strong association between T. PSA level and testosterone hormone in BPH patients, which suggested that monitoring of testosterone level is useful in patients with prostate enlargement.

Abstract
In routine hormonology, liquid chromatography mass spectrometry (LCMS) is now an established technique for androgen, urinary cortisol and metanephrine assay. It has the undeniable advantage of great analytical specificity, but with sensitivity that clearly depends on financial investment in a very high-end spectrometer. We describe the general principles of LCMS and the routine applications so far developed in hormonology. The purpose is to familiarise endocrinologists with the techniques under development and their pros and cons.

Abstract
In recent years, the progress of science and medicine greatly has influenced human life span and health. However, lifestyle habits, like physical activity, smoking cessation, moderate alcohol consumption, diet, and maintaining a normal body weight represent measures that greatly reduce the risk of various diseases. The type of diet is very important for disease development. Numerous epidemiological clinical data confirm that longevity is linked to predominantly plant-based diets and it is related to a long life; whereas the western diet, rich in red meat and fats, increases the risk of oxidative stress and thus the risk of developing various diseases and pre-aging. This review is focused on the bioavailability of polyphenols and the use of polyphenols for the prevention of prostate diseases. Special focus in this paper is placed on the isoflavonoids and flavan-3-ols, subgroups of polyphenols, and their protective effects against the development of prostate diseases.
