INTRODUCTION: Prostate cancer is the most common cancer in men and patients treated with androgen deprivation therapy (ADT) experience unfavourbale changes in body composition and associated metabolic complications, which can increase the risk of cardiovascular disease. We examined the effect of a 6-month program of aerobic and resistance exercise aimed at improving body composition and cardiorespiratory health in this population. METHODS: Ninety-seven men (43-90 years) with localized prostate cancer receiving ADT were randomized to either exercise (EX, n=50) or usual care (CON, n=47)...

BACKGROUND: Ketamine is commonly used for procedural sedation and analgesia (PSA) in children. Evidence suggests it can be administered intranasally (IN). We sought to review the evidence for IN ketamine for PSA in children. METHODS: We performed a systematic review of randomized trials of IN ketamine in PSA that reported any sedation-related outcome in children 0 to 19 years. Trials were identified through electronic searches of MEDLINE (1946-2016), EMBASE (1947-2016), Google Scholar (2016), CINAHL (1981-2016), The Cochrane Library (2016), Web of Science (2016), Scopus (2016), clinical trial registries, and conference proceedings (2000-2016) without language restrictions...

A rapid and sensitive method based on modified QuEChERS for hymexazol determination in 26 plant-derived foods using liquid chromatography tandem-mass spectrometry (LC-MS/MS) was developed. Variables affecting the separation (LC column, mobile phase additives) and clean-up effects of various dispersive phases, such as PSA, C18, GCB, MWCNTs, PEP-2, Al2O3, Florisil, and PVPP were evaluated. The method was validated using 26 matrices at spiked levels of 0.01 or 0.02, 0.05, 0.1, and 0.5mg/kg (0.05, 0.2, 0.5, and 1...

BACKGROUND: (68) Ga-PSMA-PET imaging is a novel promising diagnostic tool to locate early biochemical failure after radical prostatectomy (RP) in prostate cancer (PC) patients. Exact knowledge of the relapse location may result in changes of the therapy concept aside from changes to the TNM stage. To gain data for this approach, we evaluated PC patients receiving (68) Ga-PSMA-PET imaging before salvage radiotherapy (RT). METHODS AND MATERIALS: In this study, 100 patients with biochemical failure after RP± prior RT who underwent (68) Ga-PSMA PET/CT or PET/MRI were evaluated undergoing salvage RT in our department...

BACKGROUND: We reported that some, but not all single nucleotide polymorphisms (SNPs) in select immune response genes are associated with prostate cancer, but not individually with the prevalence of intraprostatic inflammation in the Prostate Cancer Prevention Trial (PCPT) placebo arm. Here, we investigated whether these same SNPs are associated with risk of lower- and higher-grade prostate cancer in men randomized to finasteride, and with prevalence of intraprostatic inflammation among controls...

BACKGROUND: Recent improvements in imaging diagnostics has led to a rising incidence of oligometastatic prostate cancer and, most notably, an increasing incidence of nodal-only biochemical recurrences. In this clinical setting, systemic therapy is still the treatment of choice. However, there is increasing evidence for surgical approaches in this challenging clinical setting. AIM OF THE STUDY: In this comprehensive review article, current evidence regarding surgical approaches of primary nodal metastases, nodal-only biochemical recurrence following radical prostatectomy, and osseous metastatic prostate cancer will be discussed...

We present two cases of pseudoaneurysm (PSA) about the shoulder mimicking more common clinical entities-soft tissue neoplasm and septic arthritis-for which biopsy of the mass and joint aspiration were requested respectively. We review the imaging findings of PSA with emphasis on findings in musculoskeletal protocol MRI, including the identification of pulsation artifact in both cases, which was critical to establishing the correct diagnosis. In the proper clinical setting, with imaging findings demonstrating a complex mass or fluid collection, MR images should be scrutinized for the presence of pulsation artifact, which can help diagnose a high-flow vascular lesion and avoid a potentially harmful invasive procedure such as biopsy...

LESSONS LEARNED: The combination of standard dose abiraterone acetate and BEZ235, a pan-class I PI3K and mTORC1/2 inhibitor, was poorly tolerated in men with progressive mCRPC.Although the clinical development of BEZ235 has been discontinued in prostate cancer, agents that more selectively target PI3K-AKT-mTOR signaling may have a more favorable therapeutic index and should continue to be explored. BACKGROUND: Androgen receptor (AR) and phosphatidylinositol-3 kinase (PI3K) signaling are two commonly perturbed pathways in prostate cancer...

In the COU-AA-302 trial, abiraterone acetate plus prednisone significantly increased overall survival for patients with chemotherapy-naïve metastatic castration-resistant prostate cancer (mCRPC). Limited information exists regarding response to subsequent androgen signaling-directed therapies following abiraterone acetate plus prednisone in patients with mCRPC. We investigated clinical outcomes associated with subsequent abiraterone acetate plus prednisone (55 patients) and enzalutamide (33 patients) in a post hoc analysis of COU-AA-302...

Androgen receptor (AR) is a member of the steroid receptor family and a therapeutic target for all stages of prostate cancer. AR is activated by ligand binding within its C-terminus ligand-binding domain (LBD). Here we show that overexpression of the AR NTD to generate decoy molecules inhibited both the growth and progression of prostate cancer in castrated hosts. Specifically, it was shown that lentivirus delivery of decoys delayed hormonal progression in castrated hosts as indicated by increased doubling time of tumor volume, prolonged time to achieve pre-castrate levels of serum prostate-specific antigen (PSA) and PSA nadir...

ABCG2 is a membrane transport protein that effluxes growth-promoting molecules, such as folates and dihydrotestosterone, as well as chemotherapeutic agents. Therefore it is important to determine how variants of ABCG2 affect the transporter function in order to determine whether modified treatment regimens may be necessary for patients harboring ABCG2 variants. Previous studies have demonstrated an association between the ABCG2 Q141K variant and overall survival after a prostate cancer diagnosis. We report here that in patients with recurrent prostate cancer, those who carry the ABCG2 Q141K variant had a significantly shorter time to PSA recurrence post-prostatectomy than patients homozygous for wild-type ABCG2 (P=0...

PURPOSE: We have previously demonstrated that transperineal template prostate biopsy (TPTPB) has a significantly higher cancer detection rate compared to transrectal ultrasound guided (TRUS) biopsy in biopsy naive men with a PSA < 20 ng/mL. We, therefore, performed a prospective study to determine whether TPTPB is still superior to TRUS biopsy in the detection of prostate cancer in men with persistently elevated PSA after one previous negative set of TRUS biopsies. MATERIALS AND METHODS: 42 patients with a background of one previous negative set of TRUS biopsy, persistently elevated PSA (but < 20 ng/mL) and benign feeling digital rectal examination (DRE) underwent simultaneous standard 12-core TRUS biopsy and 36-core TPTPB under general anaesthesia...
