BACKGROUND: Men diagnosed with localized prostate cancer must make a choice between treatment strategies that differ considerably in their side effects and have different long-term requirements for coping with the disease. The aim of this study was to describe how men perceive their treatment decision retrospectively and which coping strategies they use. MATERIAL & METHODS: Fifteen men (age mean=67.13±9.38 years) diagnosed with localized prostate cancer participated in three focus groups, grouped according to the treatment strategies radical prostatectomy, radiotherapy, and active surveillance...

Benign prostatic hyperplasia (BPH) is an age-related disease, affecting a majority of elderly men worldwide. Medical management of BPH is an alternative to surgical treatment of this disease. Currently, α1-adrenergic receptor (α1-AR) antagonists are among the first line drugs to treat BPH by reducing the tension of urinary track and thus the obstructive symptoms in voiding. In drug development, old male dogs with spontaneous BPH are considered the golden standard of the animal models. However, old dogs (>6 years) are expensive and not all old dogs develop BPH...

Regulator of G protein signaling (RGS) proteins temporally regulate heterotrimeric G protein signaling cascades elicited by G protein-coupled receptor activation and thus are essential for cell homeostasis. The dysregulation of RGS protein expression has been linked to several pathologies, spurring discovery efforts to identify small-molecule inhibitors of these proteins. Presented here are the results of a high-throughput screening (HTS) campaign targeting RGS17, an RGS protein reported to be inappropriately upregulated in several cancers...

OBJECTIVE: Benefit finding (BF) has exhibited a salutary effect on psychological adjustment to cancer. However, few studies have examined its relationship with physiology or have examined BF in men with cancer. This study investigated whether BF is associated with Hypothalamic-Pituitary-Adrenal (HPA) axis activity (i.e., diurnal salivary cortisol) in men treated for prostate cancer. Positive affect (PA) is proposed as a potential pathway linking BF to diurnal salivary cortisol. METHODS: A sample of 66 men treated for localized prostate cancer within the prior two years completed questionnaires and collected salivary cortisol three times per day over three consecutive days...

INTRODUCTION: Transurethral resection is currently considered as standard endoscopic treatment for lower urinary tract obstruction due to benign hyperplasia under 80 cc. Monopolar resection loops has been traditionally used but bipolar energy has recently displaced precedent technology. The purpose of this summary is to evaluate the efficacy and safety of both technologies. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others...

Prostate cancer is one of the most common forms of cancer in men, and research to find more effective and less toxic drugs has become necessary. In the frame of our ongoing program on traditionally used Salvia species from the Mediterranean Area, here we report the biological activities of Salvia aurea, S. judaica and S. viscosa essential oils against human prostate cancer cells (DU-145). The cell viability was measured by 3(4,5-dimethyl-thiazol-2-yl)2,5-diphenyl-tetrazolium bromide (MTT) test and lactate dehydrogenase (LDH) release was used to quantify necrosis cell death...

Conventional beam orientation optimization (BOO) algorithms for IMRT assume that the same set of beam angles is used for all treatment fractions. In this paper we present a BOO formulation based on group sparsity that simultaneously optimizes non-coplanar beam angles for all fractions, yielding a fraction-variant (FV) treatment plan. Beam angles are selected by solving a multi-fraction fluence map optimization problem involving 500-700 candidate beams per fraction, with an additional group sparsity term that encourages most candidate beams to be inactive...

Abiraterone acetate, which targets enzymatic complexes playing a central role in steroidogenesis, demonstrated to increase survival significantly in both chemo-naive and docetaxel pretreated, becoming one of the drugs of choice for metastatic castration-resistant prostate cancer. More recently, this agent in combination to androgen deprivation therapy demonstrated to be efficacious also in metastatic castration-sensitive prostate cancer. The present review is aimed to outline the clinical development of abiraterone acetate, the pivotal trials which led to its approval for the clinical practice, new evidence about its efficacy in metastatic castration-sensitive prostate cancer, its place in the therapeutic landscape of prostate cancer and future directions of development...

Quantitative biomarker detection methods featured with rapidity, high accuracy, and label-free are demonstrated for the development of point-of-care (POC) technologies or "beside" diagnostics. Microbead aggregation via protein-specific linkage provides an effective approach for selective capture of biomarkers from the samples, and can directly readout the presence and amount of the targets. However, sensors or microfluidic analyzers that can accurately quantify the microbead aggrega-tion are scared. In this work, we demonstrate a microwell-based microbeads analyzing system, by which online manipula-tions of microbeads including trapping, arraying, and rotations can be realized, providing a series of microfluidic approaches to layout the aggregated microbeads for further convenient characterizations...

The effect of treatment with combined butylparaben and triclosan on male gonadal toxicity in weanling rats was investigated. All treated groups experienced atrophy in the ventral prostate and seminal vesicle, likewise significant depletion in the number and motility of sperm. Given individually or combined butylparaben and triclosan, significantly decreased testosterone, luteinizing hormone, and follicle-stimulating hormone levels. Individual treatment with tested compounds caused significant elevation in the E2 level, whereas combined treatment did not alter the E2 level...

Proanthocyanidins are polymers of monomeric unit flavan-3-ols with antioxidant, anti-inflammatory and free radical scavenging activities. We investigated the association between proanthocyanidin intake and prostate cancer risk through data that were collected between 1991 and 2002 in an Italian case-control study, including a total of 1,294 incident, histologically confirmed cases of prostate cancer and 1,451 controls admitted to hospital for acute, non-neoplastic, and non-hormone-related diseases. We estimated odds ratios (ORs) and their 95% confidence intervals (CIs) using multiple logistic regression models, and computed energy-adjusted proanthocyanidin intakes using the residual method...

Pu Yuan, Dongkui Song
To reduce the side effects of chemotherapy and reach effective and safe therapy of prostate cancer, herein, a simple but multifunctional system TiO2:Gd@DOX/FA motivated by ultrasound was developed for MRI guided multi-mechanism therapy of prostate cancer. TiO2 nanoparticles served as a sonosensitizer as well as a nanocarrier with pH-responsive release of DOX. Doping of Gd could not only endow TiO2 the ability of magnetic resonance imaging (MRI), but also further improve sonodynamic ability of TiO2. The characterization revealed the as-prepared TiO2:Gd@DOX/FA showed sensitive pH-responsive drug release, high ROS production, T1-MRI contrast performance and excellent biocompatibility...

Genome-scale metabolic models have provided valuable resources for exploring changes in metabolism under normal and cancer conditions. However, metabolism itself is strongly linked to gene expression, so integration of gene expression data into metabolic models might improve the detection of genes involved in the control of tumor progression. Herein, we considered gene expression data as extra constraints to enhance the predictive powers of metabolic models. We reconstructed genome-scale metabolic models for lung and prostate, under normal and cancer conditions to detect the major genes associated with critical subsystems during tumor development...

Burkholderia pseudomallei is recognized to cause severe and fatal infections. Most of the infections caused by this facultative intracellular gram-negative bacterium are pneumonia, soft tissue, genito-urinary and central nervous system infection. We report an unusual case of primary prostatic abscess complicated by perianal abscess caused by Burkholderia pseudomallei. Melioidosis related anorectal infections have not been previously reported in the literature.
