Influence of Pulmonary Hypertension on Intrahospital Mortality in Lung Transplantation for Interstitial Lung Disease

Background

Pulmonary hypertension (PH) is a comorbidity associated with interstitial lung disease (ILD). The purpose of this study was to evaluate the influence of PH on intrahospital mortality in lung transplantation (LT) for ILD.

During the last few years, the number of patients receiving anticoagulant and antiplatelet therapy has increased worldwide. Since this is a chronic treatment, patients receiving it can be expected to need some kind of surgery or intervention during their lifetime that may require treatment discontinuation. The decision to withdraw antithrombotic therapy depends on the patient's thrombotic risk versus hemorrhagic risk. Assessment of both factors will show the precise management of anticoagulant and antiplatelet therapy in these scenarios. The aim of this consensus document, coordinated by the Cardiovascular Thrombosis Working Group of the Spanish Society of Cardiology, and endorsed by most of the Spanish scientific societies of clinical specialities that may play a role in the patient-health care process during the perioperative or periprocedural period, is to recommend some simple and practical guidelines with a view to homogenizing daily clinical practice.Full English text available from: www.revespcardiol.org/en     

Serotoninergic activation and inhibition: effects on carbohydrate tolerance and plasma insulin and glucagon.

Glucose and arginine infusion tests were performed on 12 healthy volunteers (8 males, 4 females) before and after serotoninergic activation [oral administration of L-5-hydroxytryptophan (5-HTP-) for 6 days] and serotoninergic inhibition (oral treatment with D,L-p-chloropenylalanine for 6 days). 5-HTP treatment markedly increased urinary 5-hydroxyindoleacetic acid excretion, increased the mild hyperglycemic effect of arginine infusion, and lowered the glucose disposal rate constant. The adverse effect of serotoninergic activation on glucose tolerance is not sufficiently explained by the observed changes in insulin and glucagon secretion during the fasting state and after intravenous glucose and arginine infusions. Serotoninergic inhibition did not affect the carbohydrate tolerance of normal individuals. The results of this work supports the idea that excessive indoleamine production is probably the main cause for carbohydrate intolerance in carcinoid tumors.     

Short-term Results of Liver Transplantation With Octogenarian Donors

Background

There are increasingly more patients awaiting liver transplantation while the number of donors has remained stable. It has been proven that grafts from donors older than 60 years have comparable results with those from younger donors. It is unclear whether this is so with donors older than 80 years old.

Functional Results of Renal Preservation in Hypothermic Pulsatile Machine Perfusion Versus Cold Preservation: Systematic Review and Meta-Analysis of Clinical Trials

Background

Hypothermic pulsatile machine perfusion (HPMP) decreases the rate of delayed graft function (DGF) in kidney grafts, compared with cold storage. However, it is not clear its use in the different subgroups of grafts. The objective was to review systematically all studies with better methodologic quality that compare HPMP versus cold storage.
