Esophagectomy in the Older Adult: A Systematic Review.

Current management of esophageal carcinoma (EC) involves combining different modalities, offering the opportunity of personalized strategies. This is particularly enticing in the geriatric population, where tailoring treatment modalities remains key to achieve good outcomes in terms of both quality of life and survival. Primary outcomes of our review included (1) evidence on short-term outcomes following esophagectomy, and (2) evidence on long-term outcomes following esophagectomy.

Quality of life, post-operative complications, and hernia recurrence following enhanced-view Totally Extra-Peritoneal (eTEP) Rives-Stoppa for incisional and primary ventral hernia repair.

The purpose of this study was to evaluate the quality of life (QoL), early post-operative complications, and hernia recurrence rate following laparoscopic enhanced-view Totally Extra-Peritoneal (eTEP) Rives-Stoppa (RS) for incisional and primary ventral hernia repair. Retrospective review of a prospectively maintained database of all patients undergoing eTEP-RS between 2017 and 2020. Data retrieved included demographics, and clinical and operative variables.

Bariatric Surgery in Severely Obese Kidney Donors Before Kidney Transplantation: A Retrospective Study.

Background: Bariatric surgery (BS) is the optimal approach for sustained weight loss and may alter donation candidacy in potential donors with obesity. We evaluated the long-term effects of nephrectomy after BS on metabolic profile, including body mass index, serum lipids and diabetes, and kidney function of donors.

Methods: This was a single-center retrospective study.

Unidirectional rotation of micromotors on water powered by pH-controlled disassembly of chiral molecular crystals.

Biological and synthetic molecular motors, fueled by various physical and chemical means, can perform asymmetric linear and rotary motions that are inherently related to their asymmetric shapes. Here, we describe silver-organic micro-complexes of random shapes that exhibit macroscopic unidirectional rotation on water surface through the asymmetric release of cinchonine or cinchonidine chiral molecules from their crystallites asymmetrically adsorbed on the complex surfaces. Computational modeling indicates that the motor rotation is driven by a pH-controlled asymmetric jet-like Coulombic ejection of chiral molecules upon their protonation in water.
