Influence of sarcopenia in major pancreatic surgery. A systematic review of the literature.

Post-operative morbidity of pancreatectomies occurs in up to 40-50% of patients, even in modern series. There is a need to find a simple scale in order to identify patients with increased risk of developing major post-operative complications after pancreatic resections. Many studies have been published on sarcopenia and surgical outcomes.

Synthesis of Au@Pt Core-Shell Nanoparticles as Efficient Electrocatalyst for Methanol Electro-Oxidation.

Bimetallic Au@Pt nanoparticles (NPs) with Pt monolayer shell are of much interest for applications in heterogeneous catalysts because of enhanced catalytic activity and very low Pt-utilization. However, precisely controlled synthesis with uniform Pt-monolayers and stability on the AuNPs seeds remain elusive. Herein, we report the controlled deposition of Pt-monolayer onto uniform AuNPs seeds to obtain Au@Pt core-shell NPs and their Pt-coverage dependent electrocatalytic activity for methanol electro-oxidation.

Electrochemical Study of a Hybrid Polymethyl Methacrylate Coating using SiO Nanoparticles toward the Mitigation of the Corrosion in Marine Environments.

The demand for hydrophobic polymer-based protective coatings to impart high corrosion resistance has increased recently. The increase of the hydrophobicity in a hybrid coating is a new challenge, for that reason and in order to protect a metallic surface of oxidant agents, a poly (methyl methacrylate) (PMMA) coating with the addition of a different amount of silicon dioxide (SiO) was developed. The hybrid coating was applied on a sample of stainless steel AISI 304 by the dip-coating method.

Readmission rates after laparoscopic cholecystectomy: are they affected by ERCP prior to surgery?

Aim: the aim of this study was to assess the reasons for and the time of hospital readmissions after cholecystectomy, according to whether an endoscopic retrograde cholangiopancreatography (ERCP) was performed.

Method: all patients that underwent cholecystectomy at the Service of Digestive Diseases and General Surgery of the Hospital Universitario de Guadalajara between January 2011 and December 2016 were retrospectively reviewed. Patients who underwent cholecystectomy and were readmitted to any hospital service within 90 days of surgery were included.

Intrabiliary metastases in colorectal cancer: a systematic review.

Background: Liver metastases emerge during the course of colorectal cancer (CRC) in 25-50% of patients. A small proportion of patients present intrabiliary growth. The absence of large series means that little is known about intrabiliary metastasis (IBM), its radiological diagnosis, the most suitable surgical techniques, and its prognostic implications.

Synthesis of gold nanoparticles supported on functionalized nanosilica using deep eutectic solvent for an electrochemical enzymatic glucose biosensor.

Engineering of nanoparticle (NP) surfaces offers an effective approach for the development of enzymatic biosensors or microbial fuel cells with a greatly enhanced direct electron transport process. However, lack of control over the surface functionalization process and the operational instability of the immobilized enzymes are serious issues. Herein, we demonstrate a facile and green deep eutectic solvent (DES)-mediated synthetic strategy for efficient amine-surface functionalization of silicon dioxide and to integrate small gold nanoparticles (AuNPs) for a glucose biosensor.
