Adipose tissue depot-specific intracellular and extracellular cues contributing to insulin resistance in obese individuals.

Adipose tissue dysregulation in obesity strongly influences systemic metabolic homeostasis and is often linked to insulin resistance (IR). However, the molecular mechanisms underlying adipose tissue dysfunction in obesity are not fully understood. Herein, a proteomic analysis of subcutaneous (SC) and omental (OM) fat from lean subjects and obese individuals with different degrees of insulin sensitivity was performed to identify adipose tissue biomarkers related to obesity-associated metabolic disease.

Detecting Mental Workload in Surgical Teams Using a Wearable Single-Channel Electroencephalographic Device.

Objective: To assess the sensitivity of an electroencephalographic (EEG)-based index, the prefrontal beta power, to quantify the mental workload in surgeons in real scenarios. Such EEG-based index might offer unique and unbiased measures of overload, a crucial factor when designing learning and training surgical programs.

Design: The experiment followed a 2 × 2 × 2 within subjects design with 3 factors: (1) Surgical Role during the surgery (primary surgeon vs.

Preliminary results from the use of intraoperative real-time biliary oxygen monitoring in liver transplantation.

Background And Aims: Biliary anastomosis is a frequent area of complications after liver transplantation (LT) and a potential area of "microangiopathy". The concept of a "marginal bile duct" is unexplored. The main aim was to make a preliminary evaluation of the utility of an innovative real-time oxygen microtension (pO2mt) testing device for the assessment of bile duct viability during LT and to correlate these pO2mt values with microvascular tissue quality by histopathology and outcomes.

Pancreas Donor Hypernatremia: Is it Really a Risk Factor for Simultaneous Pancreas-kidney Transplantation?

Introduction: Solid organ donor hypernatremia has been classically reported to be a risk factor for cell lysis and graft damage. National criteria for pancreatic donation consider severe hypernatremia (sodium level more than 160 mEq/L) to be relative exclusion criteria. The aim of our study is to review the postoperative outcomes of our simultaneous pancreas-kidney transplantation (SPKT) sample in terms of pancreatic fistula, intra-abdominal abscesses, pancreatitis, pancreas graft thrombosis, early pancreatectomy, and reoperation rates regarding different ranges of donor sodium levels.

Intraoperative Heparinization During Simultaneous Pancreas-Kidney Transplantation: Is It Really Necessary?

Introduction: The use of intraoperative sodium heparin during simultaneous pancreas-kidney transplantation (SPKT) remains as a routine practice in some referral centers to minimize pancreatic graft thrombosis rate. One of its disadvantages is the theoretical increased risk of postoperative bleeding. In our center, we have abandoned its use since 2011.
