Objectives: The objectives of this study are to compare the accuracy of warm ischemia times (WITs) derived by a surgical artificial intelligence (AI) software to those documented in surgeon operative reports during partial nephrectomy procedures and to assess the potential of this technology in evaluating postoperative renal function.

Patients And Methods: A surgical AI software (Theator Inc., Palo Alto, CA) was used to capture and analyse videos of partial nephrectomies performed between October 2023 and April 2024.

Purpose: In patients with prostate cancer (PCa), focal therapy with High-Intensity Focused Ultrasound (HIFU) combined with benign prostatic hyperplasia (BPH) surgery has been used to improve immediate post-operative voiding symptoms. Our study aimed to evaluate the functional outcomes of patients undergoing simultaneous holmium laser enucleation of the prostate (HoLEP) + HIFU and compare them to those who underwent HoLEP for bladder outlet obstruction secondary to BPH.

Methods: We performed retrospective review of patients who underwent HoLEP + HIFU or HoLEP between June 2017 and May 2024.

Purpose: Craniopharyngiomas (CPs) often lead to growth hormone deficiency (GHD) in children. Growth hormone replacement therapy (GHRT) is essential for managing GHD but its impact on body mass index (BMI) and metabolic outcomes is controversial. Concerns exist that GHRT might contribute to tumor recurrence, with guidelines varying on when to start therapy post-surgery.

Introduction: Treatment of type 2 diabetes (T2DM) in patients with obesity can be challenging. Metabolic and bariatric surgery (MBS) has shown promising results in improving glycemic control and even achieving remission in T2DM patients with obesity. However, the durability of glycemic improvements in T2DM patients following MBS remains insufficiently studied.

Thiadiazines are heterocyclic compounds known for some pharmacological activities. However, the ability of these compounds and their derivatives to act as antibacterial agents and inhibitors of the efflux system in resistant bacteria remains unknown. This study aims to evaluate the antibacterial and NorA efflux pump inhibitory activities of thiadiazine-derived compounds (IJ14, IJ15, IJ16, IJ17, IJ18, IJ19, and IJ20) against the Staphylococcus aureus 1199B strain.
