Learning curve analysis of extraperitoneal single-site robotic-assisted radical prostatectomy: a CUSUM-based approach.

This study applied cumulative sum (CUSUM) analysis to evaluate trends in operative time and blood loss, It aims to identify key milestones in mastering extraperitoneal single-site robotic-assisted radical prostatectomy (ss-RARP). A cohort of 100 patients who underwent ss-RARP, performed by a single surgeon at the First Affiliated Hospital of Guangzhou Medical University between March 2021 and June 2023, was retrospectively analyzed. To evaluate the learning curve, the CUSUM (Cumulative Sum Control Chart) technique was applied, revealing the progression and variability over time.

A systematic review of salivary gland hypofunction and/or xerostomia induced by non-surgical cancer therapies: prevention strategies.

Purpose: This systematic review aimed to assess the updated literature for the prevention of salivary gland hypofunction and xerostomia induced by non-surgical cancer therapies.

Methods: Electronic databases of MEDLINE/PubMed, EMBASE, and Cochrane Library were searched for randomized controlled trials (RCT) that investigated interventions to prevent salivary gland hypofunction and/or xerostomia. Literature search began from the 2010 systematic review publications from the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO) up to February 2024.

The Effect of Molten Salt Composition on Carbon Structure: Preparation of High Value-Added Nano-Carbon Materials by Electrolysis of Carbon Dioxide.

The electrochemical conversion of CO into high value-added carbon materials by molten salt electrolysis offers a promising solution for reducing carbon dioxide emissions. This study focuses on investigating the influence of molten salt composition on the structure of CO direct electroreduction carbon products in chloride molten salt systems. Using CaO as a CO absorber, the adsorption principle of CO in LiCl-CaCl, LiCl-CaCl-NaCl and LiCl-CaCl-KCl molten salts was discussed, and the reasons for the different morphologies and structures of carbon products were analyzed, and it was found that the electrolytic efficiency of the whole process exceeded 85%.

Prolonged Ovarian Stimulation Does Not Worsen Neonatal Outcomes After Fresh Embryo Transfers.

Objective: To investigate the relationship between prolonged ovarian stimulation and neonatal outcomes after autologous fresh embryo transfer (fET).

Design: A retrospective cohort study.

Setting: University-affiliated centres.

A Three-Component Reaction of Alkenyl Thianthrenium Salts, Cyclopropanols and Sulfur Dioxide.

A three-component reaction of alkenyl thianthrenium salts, cyclopropan-1-ols and DABCO·(SO) under catalyst- and additive-free conditions, is accomplished. This sulfonylation with the insertion of sulfur dioxide works efficiently under very mild conditions, leading to a wide range of 1-substituted vinyl sulfones in moderate to good yields. In this protocol, the scope generality of alkenyl thianthrenium salts and cyclopropyl alcohols is demonstrated.
