Filamin A Is a Prognostic Serum Biomarker for Differentiating Benign Prostatic Hyperplasia from Prostate Cancer in Caucasian and African American Men.

Prostate cancer represents a significant health risk to aging men, in which diagnostic challenges to the identification of aggressive cancers remain unmet. Prostate cancer screening is driven by the prostate-specific antigen (PSA); however, in men with benign prostatic hyperplasia (BPH) due to an enlarged prostate and elevated PSA, PSA's screening utility is diminished, resulting in many unnecessary biopsies. To address this issue, we previously identified a cleaved fragment of Filamin A (FLNA) protein (as measured with IP-MRM mass spectrometry assessment as a prognostic biomarker for stratifying BPH from prostate cancer and subsequently evaluated its expanded utility in Caucasian (CA) and African American (AA) men.

Study design of a phase 4, real-world study (COMPOSUR) to evaluate vibegron in patients with overactive bladder.

Background: Overactive bladder (OAB) is defined as urinary urgency accompanied by frequency and nocturia, with or without urge urinary incontinence (UUI). Vibegron, a selective β-adrenergic receptor agonist approved in the US in December 2020, demonstrated efficacy in reducing symptoms of OAB and was safe and well tolerated in the 12-week EMPOWUR trial and its 40-week, double-blind extension trial. The goal of the COMPOSUR study is to evaluate vibegron in a real-world setting to assess patient treatment satisfaction, tolerability, safety, duration of treatment, and persistence.

Vibegron for the Treatment of Patients with Dry and Wet Overactive Bladder: A Subgroup Analysis from the EMPOWUR Trial.

Background: Overactive bladder (OAB) is characterized by urgency and frequency with (OAB wet) or without (OAB dry) urge urinary incontinence (UUI). In the phase 3 EMPOWUR trial, vibegron-a selective -adrenergic receptor agonist for the treatment of OAB-significantly improved daily number of urgency episodes and micturitions vs. placebo ( < 0.

Interpretation of the Meaningfulness of Symptom Reduction with Vibegron in Patients with Overactive Bladder: Analyses from EMPOWUR.

Introduction: Reductions in bothersome symptoms of overactive bladder (OAB) demonstrate improvement in clinical trials, but patient perception of meaningfulness of such improvement is lacking. In the 12-week phase 3 EMPOWUR trial, vibegron significantly reduced average daily number of micturitions, urgency episodes, and urge urinary incontinence (UUI) episodes vs placebo (P < 0.01 each).

Role of urinary cations in the etiology of interstitial cystitis: A multisite study.

Objective: To determine whether patients with interstitial cystitis have elevated levels of toxic urinary cations, to identify and quantify these cationic metabolites, and to assess their cytotoxicity.

Methods: Isolation of cationic fraction was achieved by solid phase extraction using an Oasis MCX cartridge on urine specimens from interstitial cystitis patients and controls. C reverse phase high-performance liquid chromatography was used to profile cationic metabolites, and they were quantified by the area under the peaks and normalized to creatinine.

Taking OAB seriously: A qualitative evaluation of primary care education on overactive bladder syndrome management.

Background: Overactive bladder (OAB) syndrome has a diverse etiology that disrupts quality of life domains in affected patients. OAB is significantly under-recognised and undertreated, especially in the primary care setting. In order to educate primary care providers about OAB recognition, evaluation and management, we created a virtual live-streamed and enduring education program.

Cardiovascular risk with androgen deprivation therapy.

Background: From the primary care perspective, many urologists and oncologists appear to be ignoring an FDA warning to assess patients' cardiovascular (CV) risk before instituting androgen deprivation therapy (ADT) with gonadotropin-releasing hormone (GnRH) agonists. A growing body of data suggest an association between ADT and CV/cardiometabolic risk, particularly for GnRH agonists.

Methodology: The author examined available evidence regarding CV side effects with GnRH agonists and antagonists to determine what urologists, medical oncologists, primary care physicians (PCPs) and patients need to know about these risks.

Efficacy of Continuous Dosing of Tadalafil Once Daily vs Tadalafil On Demand in Clinical Subgroups of Men With Erectile Dysfunction: A Descriptive Comparison Using the Integrated Tadalafil Databases.

Introduction: Various factors play a role in the development of erectile dysfunction (ED).

Aim: To provide a descriptive comparison of erectile function response for tadalafil on-demand (PRN) and once-daily (OAD) dosing regimens in patients with common comorbid conditions, treatments, or risk factors that can be considered when treating ED.

Methods: In total, 17 PRN and 4 OAD placebo-controlled studies were included in the integrated database in these pooled analyses.

A practical primary care approach to lower urinary tract symptoms caused by benign prostatic hyperplasia (BPH-LUTS).

In the primary care office the evaluation of prostate related lower urinary tract symptoms (BPH-LUTS) in the male can be confusing. Are the symptoms, in fact, from the prostate or is there another etiology such as the bladder or medical conditions causing or contributing to the problems? If the cause is the prostate, how does the physician choose from the multitude of available treatment options and when is referral appropriate? The prevalence of BPH-LUTS is high and commonly encountered by the primary care physician (PCP). An understanding of the normal prostate is essential to identifying the patient when symptoms do occur.

A practical primary care approach to overactive bladder.

The evaluation and treatment of overactive bladder (OAB) starts in the primary care office and can be accomplished efficiently, effectively and, most importantly, safely. With appropriate knowledge of the disease and an understanding of what to look for the primary care physician (PCP) can readily make the empiric diagnosis and initiate treatment. The key for the PCP is to be able to distinguish the uncomplicated patient from the complicated one and know when to refer, if necessary.

Stopwatch-assessed duration of erection: a new measure of the efficacy of erectile dysfunction treatments.

Results are reported from the first two adequate trials of the PDE-5 inhibitor vardenafil using a stopwatch to precisely measure erection duration in men with ED. Two randomized, multicenter, double-blind, placebo-controlled trials were conducted: a crossover 4-week treatment in men with ED (ENDURANCE) and a parallel group, 12-week treatment in men with ED and dyslipidemia (the dyslipidemia study). Stopwatch-assessed duration of erection leading to successful intercourse measured by Sexual Encounter Profile question-3 (SEP-3) was the primary end point in ENDURANCE and one of the secondary end points in the dyslipidemia study.

Biology and natural history of prostate cancer and the role of chemoprevention.

Androgens not only play an important role in the development and function of the prostate but they are also intimately involved in the development and progression of prostate cancer (PCa). Within the prostate, testosterone is converted to the more potent androgen dihydrotestosterone (DHT) via the action of 5α-reductase enzymes. DHT is the primary prostatic androgen and promotes the growth and survival of normal, hyperplastic and malignant prostate tissues.

STEP: simplified treatment of the enlarged prostate.

We propose a simple and practical approach to the identification, evaluation and treatment of lower urinary tract symptoms (LUTS) resulting from an enlarging and obstructive prostate. The proposed Simplified Treatment for Enlarged Prostate (STEP) plan is a logical guide to patient management by the primary care provider (PCP). Symptoms of enlarged prostate (EP) are common and may frequently progress into a condition with profound adverse effects on quality of life.

The role of tramadol ER in the treatment of chronic pain.

Despite its high prevalence, chronic pain is suboptimally treated in approximately one half of affected patients. Failure to recognise and manage comorbid physical and psychosocial impairments may contribute to the perpetuation of chronic pain. Knowledge of the potential advantages and disadvantages of available analgesic medications will permit informed selection of the appropriate medication for the individual chronic pain patient.

Improvement in duration of erection following phosphodiesterase type 5 inhibitor therapy with vardenafil in men with erectile dysfunction: the ENDURANCE study.

Objective: The ENDURANCE study evaluated the efficacy of vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor, in men with erectile dysfunction (ED), by measuring the duration of erection leading to successful intercourse using a stopwatch as the assessment instrument.

Methods: This was a randomised, multicentre, double-blind, placebo-controlled, crossover study consisting of a 4-week treatment-free run-in phase after which patients were randomised to either fixed-dose vardenafil 10 mg or placebo (to be administered 60 min prior to intercourse) and entered the first of the two 4-week double-blind treatment periods, separated by a 1-week washout. The primary efficacy end-point was the stopwatch-assessed duration of erection, which was defined as the time from erection perceived hard enough for penetration until withdrawal from the partner's vagina leading to successful intercourse as measured by Sexual Encounter Profile Question 3 (SEP-3).

Patient response in a screened population for interstitial cystitis.

The purpose of this study was to screen a general patient population for interstitial cystitis (IC) and to determine the outcome of combination therapy (pentosan polysulfate sodium [PPS] and hydroxyzine) in newly diagnosed patients. Screening for IC symptoms was performed on 3883 patients (>or=18 yr of age). After further evaluation, a diagnosis of IC was made in 160 patients.

A practical guide to the evaluation and treatment of male lower urinary tract symptoms in the primary care setting.

Aims: Lower urinary tract symptoms (LUTS) are common in both men and women, and are among the most prevalent patient complaints heard by primary care physicians (PCPs). This article aims to provide PCPs with a logical algorithm for the assessment and initiation of treatment for LUTS in the male patient.

Results: Management of LUTS involves a focused history and physical, as well as the assessment of bother.

Diagnosis and management of erectile dysfunction in the primary care setting.

Recent advances in the management of erectile dysfunction (ED) involve the use of oral phosphodiesterase type-5 (PDE-5) inhibitor therapies which have transformed the perception of ED for both the patient and the healthcare provider. Recent treatment guidelines, including the American Urological Association (AUA) 2005 guidelines, promote a goal-oriented approach to therapy and emphasise that PDE-5 therapy should be offered to patients with ED as a first-line treatment option, unless contraindicated. Evidence-based studies have identified an association between ED and the presence of risk factors for cardiovascular and other vascular diseases, implicating ED as a marker for other vascular conditions.
