Association between the use of proton pump inhibitors and serum PSA levels in the general U.S. population.

Background: Proton pump inhibitors (PPIs) are widely prescribed drugs that have been associated with increased prostate cancer (PCa) cell proliferation in vitro and worse oncological outcomes in vivo. However, data on their influence on PSA levels in the general population are lacking.

Methods: We extracted individual participant data from the 2001-2010 cycles of the National Health and Nutrition Examination Survey (NHANES), in which PSA levels were measured in all male participants aged 40 years or older.

The efficacy of intra-articular corticosteroid injections for elbow arthritis: a retrospective cohort study.

Purpose: The goal of this study was to report the duration of pain relief and need for subsequent surgical intervention following intra-articular steroid injection of the elbow in the setting of arthritis.

Methods: The authors' institutional database was accessed to identify patients who underwent a corticosteroid injection of the elbow for arthritis. For included patients, demographic information, steroid dosage, duration of symptoms relief, complications, and progression to surgical management were recorded.

Purpose: To assess the survival outcomes of adjuvant radiation therapy (aRT) vs observation with or without early salvage RT (Obs ± esRT) for cN0M0 pN1 prostate cancer (PCa) and to create a model for clinical decision-making.

Materials And Methods: We retrospectively identified 1103 patients with cN0M0 PCa with pN1 PCa after surgery (2000-2021) at 18 referral centers. Kaplan-Meier curves and Cox proportional hazards models were used.

TIME-CoExpress: Temporal Trajectory Modeling of Dynamic Gene Co-expression Patterns Using Single-Cell Transcriptomics Data.

The rapid advancements of single-cell RNA sequencing (scRNAseq) technology provide high-resolution views of transcriptomic activity within a single cell. Most routine analyses of scRNAseq data focus on individual genes; however, the one-gene-at-a-time analysis is likely to miss meaningful genetic interactions. Gene co-expression analysis addresses this issue by identifying coordinated gene expression changes in response to cellular conditions, such as developmental or temporal trajectory.

External Validation of Nomograms for the Identification of Pelvic Nodal Dissection Candidates Among Prostate Cancer Patients with Negative Preoperative Prostate-specific Membrane Antigen Positron Emission Tomography.

Patients: Patients from the IDENTIFY dataset; Patients referred to secondary care with suspected urinary tract cancer and found to have isolated de novo red patches on cystoscopy.

Methods: We reported the unadjusted cancer prevalence in isolated de novo red patches that were biopsied; multivariable logistic regression was used to explore cancer-associated risk factors including age, sex, smoking, type of haematuria, LUTS, UTIs and a suspicious-looking red patch (as reported by the cystoscopist).

Characterisation of the optical response to seismic waves of submarine telecommunications cables with distributed and integrated fibre-optic sensing.

We present the first controlled-environment measurements of the optical path-length change response of telecommunication submarine cables to active seismic and acoustic waves. We perform the comparison among integrated (optical interferometry) and distributed (distributed acoustic sensing, DAS) fibre measurements and ground truth data acquired by 58 geophones, 20 three-axis seismometers and 7 microphones. The comparison between different seismic acquisition methods is an essential step towards full validation and calibration of the data acquired using novel cable-based sensing techniques.

Histopathologic Features and Transcriptomic Signatures Do Not Solve the Issue of Magnetic Resonance Imaging-Invisible Prostate Cancers: A Matched-Pair Analysis.

Background: Multiparametric magnetic resonance imaging (mpMRI) is pivotal in prostate cancer (PCa) diagnosis, but some clinically significant (cs) PCa remain undetected. This study aims to understand the pathological and molecular basis for csPCa visibility at mpMRI.

Prostate cancer in solid organ transplant recipients: Results from a multicenter series.

Introduction: Prostate cancer incidence in immunosuppressed transplant recipients increases as life expectancy improves in this population. However, the management of treatments and immunosuppressive (IS) regimens for solid organ transplant recipients diagnosed with prostate cancer remains poorly defined. Therefore, we conducted a multicentric study to investigate these parameters more thoroughly.

The Added Value of Prostate-specific Membrane Antigen Positron Emission Tomography/Computed Tomography to Magnetic Resonance Imaging for Local Staging of Prostate Cancer in Patients Undergoing Radical Prostatectomy.

Background And Objective: The role of prostate-specific membrane antigen (PSMA)-based positron emission tomography (PET)/computed tomography (CT) in addition to magnetic resonance imaging (MRI) for local staging of prostate cancer (PC) has been poorly addressed so far. Our aim was to assess the diagnostic accuracy of PSMA PET/CT and MRI, alone and combined, for detection of extraprostatic extension (EPE) and seminal vesicle invasion (SVI) in PC.

Methods: We conducted a multicenter retrospective study evaluating patients undergoing PSMA PET/CT and MRI before radical prostatectomy.

Follow-up on patients with initial negative mpMRI target and systematic biopsy for PI-RADS ≥ 3 lesions - an EAU-YAU study enhancing prostate cancer detection.

Purpose: To investigate the detection and predictors of prostate cancer (PCA) and clinically significant prostate cancer (csPCA) in patients with positive multiparametric MRI (mpMRI) followed by a negative MRI - guided target biopsy (TB) and systematic biopsy (SB).

Materials And Methods: This retrospective multicenter study included 694 patients from 10 tertiary referral centers with an initial positive mpMRI (PI-RADS ≥ 3) and negative results on both MRI-TB and SB. Patients were classified into three groups based on follow-up: Group 1 (prostate re-biopsy without new mpMRI), Group 2 (standardized second prostate mpMRI and subsequent re-biopsy), and Group 3 (follow-up with mpMRIs and biopsy based on clinical and radiological triggers).

The Critical Shoulder Angle as a Highly Specific Predictor of a Full-Thickness Rotator Cuff Tear: A Case-Control Study.

Background: The critical shoulder angle (CSA) has become an important topic of study in patients with rotator cuff tears (RCTs). However, there are conflicting data on whether the CSA can differentiate between patients with normal shoulder pathology and full-thickness RCTs on shoulder radiographs.

Purpose/hypothesis: The purpose of this study was to define the relationship between full-thickness RCTs and the CSA.

Combined Role of {001} Facet-Enriched Morphology and Gold Nanoparticle Deposition on Anatase TiO Photoactivity.

The interplay on anatase TiO photoactivity between particle morphology and gold nanoparticles (NPs) deposition, via either deposition-precipitation (DP) or photodeposition (P), is here investigated by evaluating the photoactivity of Au modified anatase (Au/TiO) nanocrystals with either a pseudospherical shape or a nanosheet structure in both reduction and oxidation test reactions. The presence of Au NPs on the anatase surface only slightly affects its photoactivity in Cr(VI) reduction, which is kinetically limited by the anodic half-reaction, whereas a larger exposure of highly oxidant {001} facets is beneficial for overcoming this rate-determining step. In the photocatalytic oxidation of both formic acid, proceeding through a direct mechanism, and rhodamine B (RhB) on surface fluorinated photocatalysts, occurring through a hydroxyl-radical-mediated mechanism, the presence of gold NPs produces a significant photoactivity increase only with spherically shaped photocatalysts, mainly exposing {101} facets.

Surveillance after Focal Therapy - a Comprehensive Review.

Background: to date, no standardized, evidence-based follow-up schemes exist for the monitoring of patients who underwent focal therapy (FT) and expert centers rely mainly on their own experience and/or institutional protocols. We aimed to perform a comprehensive review of the most advantageous follow-up strategies and their rationale after FT for prostate cancer (PCa).

Methods: a narrative review of the literature was conducted to investigate different follow-up protocols of FT for PCa.

Observation With or Without Subsequent Salvage Therapy for Pathologically Node-positive Prostate Cancer With Negative Conventional Imaging: Results From a Large Multicenter Cohort.

Background And Objective: More than 10% of patients with negative clinical metastatic status (cN0M0) on conventional imaging for prostate cancer (PCa) harbor lymph node involvement (pN+) at final pathology following radical prostatectomy (RP) and lymphadenectomy. Our aim was to assess outcomes of initial observation for cN0M0 pN+ PCa and identify prognostic factors that may help in clinical decision-making.

Methods: We performed a retrospective multicenter study of patients with cN0M0 PCa on conventional imaging (computed tomography and/or magnetic resonance imaging, and a bone scan) who were found to have pN+ disease at RP between 2000 and 2021.

Global Health Inequities in Orthopaedic Care: Perspectives Beyond the US.

Purpose Of Review: The burden of musculoskeletal disease is increasing globally and disproportionately affecting people in low and middle income countries (LMIC). We sought to review global access to orthopaedic care, burden of trauma, research infrastructure, impact of surgical mission trips, implant availability, and the effect of COVID-19 upon the delivery of orthopaedic care worldwide.

Recent Findings: The majority of people in LMIC do not have access to safe, quality surgical care, and there are few fellowship-trained orthopaedic traumatologists.

Local salvage therapies in patients with radio-recurrent prostate cancer following external beam radiotherapy: a systematic review and meta-analysis.

Introduction: To date, radio-recurrent prostate cancer (PCa) ranks as the fourth most common urological malignancy when considering the number of men with localized PCa who undergo radiation treatment and subsequently experience a biochemical recurrence. This systematic review aimed to summarize available evidence about the outcomes of local salvage strategies in patients with local PCa recurrence following primary external-beam radiation therapy (EBRT).

Methods: We conducted a comprehensive bibliographic search on MEDLINE, Scopus, and Web of Science Core Collection databases in October 2023 to identify studies published in the last 20 years evaluating outcomes of local salvage procedures in patients with locally radio-recurrent PCa following EBRT.

Testing for similarity of multivariate mixed outcomes using generalized joint regression models with application to efficacy-toxicity responses.

A common problem in clinical trials is to test whether the effect of an explanatory variable on a response of interest is similar between two groups, for example, patient or treatment groups. In this regard, similarity is defined as equivalence up to a pre-specified threshold that denotes an acceptable deviation between the two groups. This issue is typically tackled by assessing if the explanatory variable's effect on the response is similar.
