cfDNA fragmentation patterns correlate with tumor burden measured via PSMA PET/CT volumetric parameters in patients with biochemical recurrence of prostate cancer.

Background: Prostate cancer recurrence following primary treatment poses a significant clinical challenge, particularly when detected through biochemical recurrence at low PSA levels. Conventional imaging modalities often fail to localize the disease at this early stage. PSMA PET has demonstrated superior sensitivity in detecting recurrent lesions, even in patients with low PSA.

Definition of Progressive Keratoconus: A Systematic Review.

Purpose: To identify the definitions used for progressive keratoconus in the literature.

Methods: A systematic literature review aimed to identify the definitions used for "progressive keratoconus" in the published articles. A comprehensive search from January 2018 to May 2023 was conducted across Cochrane Library, PubMed, Taylor & Francis, Web of Science, and other bibliographic databases at Oftalmosalud, Lima, Peru.

Enhancing corneal ectasia susceptibility detection: analysis of a new algorithm (BAD-D v4).

Accurate detection of post-refractive ectasia susceptibility is essential during preoperative evaluation for laser vision correction (LVC) due to the risk of progressive corneal ectasia and vision decline post-surgery. Despite improved screening and a reduced incidence from 0.66 to 0.

Role of Liquid Biopsy in Progressive PSA Patients after Radical Prostatectomy.

Currently, the prediction of disease recurrence after radical prostatectomy (RP) in localized prostate cancer (PCa) relies on clinicopathological parameters, which lack accuracy in predicting clinical outcomes. This study focused on evaluating the utility of cfDNA levels and fragmentation patterns as prognostic biomarkers in progressive prostate-specific antigen (PSA) patients, including those with persistent PSA and biochemical recurrence (BR), after primary treatment in localized PCa patients. Twenty-nine high-risk localized PCa patients were enrolled in the study between February 2022 and May 2023.

Intravenous indocyanine green to evaluate distal ureteral vascularity during robot-assisted radical cystectomy with intracorporeal urinary diversion.

Purpose: The aim of the present study is to assess the role of indocyanine green (ICG) to evaluate distal ureteral vascularity during robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion and its impact on the incidence of benign ureteroenteric strictures (UES).

Methods: The study included patients who underwent RARC for bladder cancer between 2018 and 2023. All patients included underwent intracorporeal urinary diversion with ileal conduit or neobladder.
