Introduction: Due to the growing medical need for gynecologic robotic surgery, several robotic surgeries may be performed in a single day at high-volume centers. This study evaluated the safety of performing multiple robot-assisted hysterectomies (RAHs) per day by the same surgeon.
Methods: We reviewed the clinical data of patients who underwent robotic surgery from April 2018 to September 2024 at the Department of Gynecology, Yamanashi Central Hospital, and also examined the surgical type, order, and surgeon for each procedure.
Article Synopsis
- * A study on mice with reduced mitochondrial superoxide dismutase (SOD2) showed that a lack of this enzyme led to increased muscle glycogen and motor dysfunction, indicating a link between mitochondrial health and muscle performance.
- * The research found that the enzyme responsible for breaking down glycogen (GP-M) was less active in these mice and could be restored by antioxidants, suggesting that maintaining mitochondrial redox balance is crucial for proper glycogen metabolism and muscle function.
Pulmonary valve replacement for porcelain right ventricular outflow tract following repeated surgical intervention.
Gen Thorac Cardiovasc Surg Cases
January 2024
Article Synopsis
- * A 43-year-old patient with a history of multiple valve replacements experienced severe heart failure and protein loss, but was successfully treated with additional valve replacements using a mechanical valve despite significant surgical risks due to adhesions and calcification.
- * The surgery provided relief from heart failure and related symptoms, demonstrating that this approach can yield better results compared to traditional methods when dealing with severe complications in the right ventricular outflow tract.
Insights of energy potential in thermophilic sugarcane vinasse and molasses treatment: does two-stage codigestion enhance operational performance?
Biodegradation
October 2024
The study evaluated the performance of thermophilic co-digestion in both single-stage methanogenic reactors (TMR) and two-stage systems, consisting of a thermophilic acidogenic reactor and a thermophilic sequential methanogenic reactor (TSMR). A 1:1 mixture of sugarcane vinasse and molasses was codigested in anaerobic fluidized bed reactors, with varying organic matter concentrations based on chemical oxygen demand (COD) ranging from 5 to 22.5 g COD L.

This study assessed the impact of organic loading rate (OLR) on methane (CH) production in the anaerobic co-digestion (AcoD) of sugarcane vinasse and molasses (SVM) (1:1 ratio) within a thermophilic fluidized bed reactor (AFBR). The OLR ranged from 5 to 27.5 kg COD.
