Eco-Friendly Waterborne Polyurethane Coating Modified with Ethylenediamine-Functionalized Graphene Oxide for Enhanced Anticorrosion Performance.

This study explores the potential of graphene oxide (GO) as an additive in waterborne polyurethane (WPU) resins to create eco-friendly coatings with enhanced anticorrosive properties. Traditionally, WPU's hydrophilic nature has limited its use in corrosion-resistant coatings. We investigate the impact of incorporating various GO concentrations (0.

Is Nipple-Sparing Mastectomy Indicated after Previous Breast Surgery? A Series of 387 Institutional Cases.

Background: Previous breast surgery does not represent an absolute contraindication for nipple-sparing mastectomy, although it may negatively interfere with surgical outcomes. The aim of the authors' study was to confirm the feasibility of nipple-sparing mastectomy after previous breast surgery, focusing on skin incisions and risk factors, complications, and oncologic outcomes.

Methods: The authors retrospectively identified 368 patients who underwent 387 nipple-sparing mastectomies and reconstruction after previous surgery (quadrantectomy, breast resection, augmentation and reduction mammaplasty, mastopexy) at the European Institute of Oncology from January of 2003 to November of 2017.

Educational impact of hand motion analysis in the evaluation of FAST examination skills.

Purpose: Increasing pressure pushes towards the objective competence assessment of clinical operators. Hand motion analysis (HMA) was introduced to measure surgical and clinical procedures; its recent application to FAST examinations leaves unsolved issues. This study aimed at determining optimal HMA parameters to discriminate between operators' skill levels, and which FAST tasks are experience-dependent.

Failure to Rescue, Rescue Surgery and Centralization of Postoperative Complications: A Challenge for General and Acute Care Surgeons.

Purpose Of Review: To explore the current literature on the failure to rescue and rescue surgery concepts, to identify the key items for decreasing the failure to rescue rate and improve outcome, to verify if there is a rationale for centralization of patients suffering postoperative complications.

Recent Findings: There is a growing awareness about the need to assess and measure the failure to rescue rate, on institutional, regional and national basis. Many factors affect failure to rescue, and all should be individually analyzed and considered.

Laparoscopic and ultrasound assisted management of gallstone ileus after biliointestinal bypass Case report and a review of literature.

Aim: To report about an additional case of biliary ileus after bariatric surgery is reported and extensively reviewing the literature on this topic.

Material Of Study: We reviewed the literature and found three cases of gallstone ileus (GI) that occurred after bariatric surgery.

Discussion: A 41 year old patient presented a GI eight years after a biliointestinal bypass (BIB) for morbid obesity.
