Do 5-Alpha Reductase Inhibitors Influence the Features of Suspicious Lesions on Magnetic Resonance Imaging and Targeted Biopsy Results for Prostate Cancer Diagnosis?

Background: 5-alpha reductase inhibitors (5-ARIs) change hormonal pathways and reduce prostate size. We evaluated the effects of 5-ARIs on prostatic multiparametric magnetic resonance imaging (mpMRI) suspicious findings and in the identification of prostate cancer using targeted biopsies.

Methods: We conducted a retrospective study including 600 consecutive patients who, between 2017 and 2021, underwent combined transperineal fusion biopsies.

Parental regret following decision for sons to undergo elective post-neonatal circumcision.

Introduction: The reasons for performing a circumcision among males after the neonatal period are usually cultural or medical. We aimed to evaluate parental regret for providing consent and to identify factors associated with such regret.

Methods: Included were the parents of males aged 6 months to 18 years who underwent circumcision under general anesthesia at a single center between 2/2017 and 01/2023.

Face naming and recollection represent key memory deficits in developmental prosopagnosia.

Previous studies have found that face perception deficits do not fully account for the severity of face recognition deficits in developmental prosopagnosia (DP). Researchers have begun identifying deficient memory mechanisms such as impaired face recollection, but these findings require replication, and further characterization of additional memory deficits is necessary. Our goals were to replicate prior findings of face recollection impairment in DP and extend these findings to assess different types of face associative memory.

Interpersonal emotion regulation and depressive symptoms in parent-adolescent dyads: A daily-diary investigation.

Deficient parental extrinsic (IER, how people regulate others' emotions) is a known risk factor for adolescent depression. Although IER and depression development are transactional, dyadic processes, previous work has almost exclusively focused on how parental IER is associated with adolescent depression. The association between parental IER and adolescent depression, and the associations between adolescent IER and adolescent and parental depression have received little attention.

MRI-based PI-RADS score predicts ISUP upgrading and adverse pathology at radical prostatectomy in men with biopsy ISUP 1 prostate cancer.

Introduction: Most men diagnosed with very-low and low-risk prostate cancer are candidates for active surveillance; however, there is still a misclassification risk. We examined whether PI-RADS category 4 or 5 combined with ISUP 1 on prostate biopsy predicts upgrading and/or adverse pathology at radical prostatectomy.

Materials And Methods: A total of 127 patients had ISUP 1 cancer on biopsy after multiparametric MRI (mpMRI) and then underwent radical prostatectomy.

Increased prevalence of non-E. coli bacteria-caused urinary infection in neonates delivered by cesarian section.

Objectives: to assess the association between delivery mode and causative pathogens of infants with urinary tract infections.

Materials And Methods: We conducted a retrospective analysis of the medical records of neonates delivered in a tertiary academic pediatric hospital and diagnosed with urinary tract infections between January 1,2013 and December 31,2017. Excluded were newborns with urinary tract infections post-urological procedures or neurogenic bladders.

Optimizing Colon Identification by Window Setting Modulation on Noncontrast Computed Tomography Prior to Percutaneous Nephrolithotomy.

Preoperative identification of the bowel on imaging is essential in planning renal access during percutaneous nephrolithotomy (PCNL) and avoiding colonic injury. We aimed this study to assess which noncontrast computed tomography (NCCT) window setting provides the optimal colonic identification for PCNL preoperative planning. Ten urologic surgeons (four seniors, six residents) reviewed 22 images of NCCT scans in both abdomen and lung window settings in a randomized blinded order.

Association between White Matter T2 Hyper-Intense Signals in Fetal Brain Magnetic Resonance Imaging and Neurodevelopment of Fetuses with Cytomegalovirus Infection.

An association between subtle changes in T2 white matter hyper-intense signals (WMHSs) detected in fetal brain magnetic resonance imaging (fbMRI) and congenital cytomegalovirus (CMV) infection has been established. The research aim of this study is to compare children with congenital CMV infection with neurodevelopment outcome and hearing deficit with and without WMHSs in a historic prospective case study cohort of 58 fbMRIs. Of these, in 37 cases, fbMRI was normal (normal group) and WMHSs were detected in 21 cases (WMHS group).

Diverging co-translational protein complex assembly pathways are governed by interface energy distribution.

Protein-protein interactions are at the heart of all cellular processes, with the ribosome emerging as a platform, orchestrating the nascent-chain interplay dynamics. Here, to study the characteristics governing co-translational protein folding and complex assembly, we combine selective ribosome profiling, imaging, and N-terminomics with all-atoms molecular dynamics. Focusing on conserved N-terminal acetyltransferases (NATs), we uncover diverging co-translational assembly pathways, where highly homologous subunits serve opposite functions.

Exploring the Possible Role of Cannabinoids in Managing Post-cardiac Surgery Complications: A Narrative Review of Preclinical Evidence and a Call for Future Research Directions.

Open-heart surgery with cardiopulmonary bypass often leads to complications including pain, systemic inflammation, and organ damage. Traditionally managed with opioids, these pain relief methods bring potential long-term risks, prompting the exploration of alternative treatments. The legalization of cannabis in various regions has reignited interest in cannabinoids, such as cannabidiol, known for their anti-inflammatory, analgesic, and neuroprotective properties.

A combined MRI-PSAD risk stratification system for prioritizing prostate biopsies.

Introduction:   Prostate cancer screening with PSA is associated with low specificity; furthermore, little is known about the optimal timing of biopsy.  We aimed to evaluate whether a risk classification system combining PSA density (PSAD) and mpMRI can predict clinically significant cancer and determine biopsy timing.

Materials And Methods:  We reviewed the medical records of 256 men with a PI-RADS ≥ 3 lesion on mpMRI who underwent transperineal targeted and systematic biopsies of the prostate between 2017-2019.

Megameatus intact prepuce variant reconstruction: Long-term outcomes and comparison to post-circumcision hypospadias repair.

Background: Megameatus intact prepuce (MIP) variant is considered a surgical challenge with associated high complication rates. It is usually diagnosed and corrected only after neonatal circumcision, which is discouraged in non-MIP hypospadias.

Objective: In order to determine whether the features of the MIP variant or the performance of a secondary reconstruction following circumcision comprise the cause of higher complication rates, we now compared the results of post-circumcision MIP hypospadias repair to the results of children who underwent repair of non-MIP hypospadias following neonatal circumcision.

Mini-HoLEP (MILEP) vs HoLEP: a propensity score-matched analysis.

Background And Purpose: Minimal invasiveness improves outcome in many surgical fields including urology. We aimed to assess intraoperative performance and clinical outcome of miniaturized holmium laser enucleation of prostate (MiLEP) (22FR).

Methods: We ran a propensity score-matched analysis among all consecutive laser enucleations of prostate performed between 9/2022 and 2/2023.

Complete Blood Count Markers and C-Reactive Protein as Predictors of Testicular Viability in the Event of Testicular Torsion in Adults.

Introduction: The association between blood markers and testicular viability after testicular torsion (TT) is not well known. We evaluated the role of complete blood count markers and C-reactive protein (CRP) in predicting testicular viability after TT.

Methods: Fifty men, ≥18 years of age, operated for TT between the years 2015-2020 were enrolled.

The role of tumor density in predicting significant cancer on targeted biopsy of the prostate.

Objective: Multiparametric magnetic resonance imaging (mpMRI) is central to diagnosing prostate cancer; however, not all imaged lesions represent clinically significant tumors. We aimed to evaluate the association between the relative tumor volume on mpMRI and clinically significant prostate cancer on biopsy.

Materials And Methods: We retrospectively reviewed the medical records of 340 patients who underwent combined transperineal targeted and systematic prostate biopsies between 2017 and 2021.

Periprocedural antibiotics for urodynamic studies of pediatric neurogenic bladder, empiric or culture-guided? A retrospective cohort study.

Introduction: Urodynamic studies are fundamental in the care of children with neurogenic bladder. Children with neurogenic bladder who perform clean intermittent catheterization (CIC) are considered a high-risk group for infection after urodynamic studies. Current guidelines are not uniform regarding the duration, type, the need of prophylactic antibiotic treatment or performance of urine culture before urodynamic studies.

Congenital hypotonia: systematic approach for prenatal detection.

Objectives: Congenital hypotonic conditions are rare and heterogeneous, and some are severely debilitating or lethal. Contrary to its prominent postnatal manifestation, the prenatal presentation of hypotonia is frequently subtle, inhibiting prenatal detection. We aimed to characterize the prenatal sonographic manifestation of congenital hypotonia throughout pregnancy, evaluate the yield of diagnostic tests and propose diagnostic models to increase its prenatal detection.

Exstrophy-epispadias complex: are the kidneys and kidney function spared?

Background: Exstrophy-epispadias complex (EEC) is a complex malformation of the lower abdominal wall, bladder, and pelvic floor, which necessitates multiple successive reconstruction procedures. Surgical and infectious complications are frequent. Our aim was to evaluate kidney function in these patients.

Implementing a screening algorithm for early recognition of sepsis in hospitalized children: a quality improvement project.

Sepsis is a leading cause of mortality in children. Utilizing a screening tool for early recognition of sepsis is recommended. Our centre had no screening tool for sepsis nor a standardized protocol for sepsis management.

External validation of a simplified prognostic model for survival in patients with extrinsic malignant ureteral obstruction treated with tandem ureteral stents - a retrospective cohort study.

Introduction: Prognostic models of survival can identify patients with extrinsic malignant ureteral obstruction who will benefit from long-term drainage as offered by tandem ureteral stents. The study aims to validate a simplified prognostic model published by Cordeiro et al. and to identify additional prognostic predictors in a cohort of patients drained solely with tandem ureteral stents.

The role of serum and urinary markers in predicting obstructing ureteral stones and reducing unjustified non-contrast computerized tomographic scans in emergency departments.

Introduction: The reported yield of non-contrast computed tomography (NCCT) in assessing flank pain and obstructive urolithiasis (OU) in emergency departments (EDs) is only ~ 50%. We investigated the potential capability of serum and urinary markers to predict OU and improve the yield of NCCT in EDs.

Methods: All consecutive ED patients with acute flank pain suggestive of OU and assessed by NCCT between December 2019 and February 2020 were enrolled.
