Metabolomic profiling of cardiac allografts after controlled circulatory death.

Background: Assessment of myocardial viability during ex situ heart perfusion (ESHP) is based on the measurement of lactate concentrations. As this provides with limited information, we sought to investigate the metabolic signature associated with donation after circulatory death (DCD) and the impact of ESHP on the myocardial metabolome.

Methods: Porcine hearts were retrieved either after warm ischemia (DCD group, N = 6); after brain-stem death (BSD group, N = 6); or without DCD nor BSD (Control group, N = 6).

Risk stratification and treatment of pulmonary embolism with intermediate-risk of mortality.

Purpose Of Review: Intermediate-risk pulmonary embolisms (PE) represent a heterogeneous group at the high end of hemodynamically stable patients, characterized by a higher mortality rate. This challenging population gathers many unsolved question regarding its therapeutic management. The purpose of this review is to provide an updated overview of the literature regarding further risk stratification and treatment options in this population.

Lung cancer is also a hereditary disease.

Pathogenic genetic variants (formerly called mutations) present in the germline of some individuals are associated with a clinically relevant increased risk of developing lung cancer. These germline pathogenic variants are hereditary and are transmitted in an autosomal dominant fashion. There are two major lung cancer susceptibility syndromes, and both seem to be specifically associated with the adenocarcinoma subtype.

Encephalitis related to immunotherapy for lung cancer: Analysis of a multicenter cohort.

Introduction: Using immune-checkpoint inhibitors (ICIs) to manage cancer is associated with various immune-related adverse events. Central and/or peripheral neurological disorders are rare and potentially serious. We analyzed the characteristics of non-small-cell lung cancer (NSCLC) patients who developed immune-related encephalitis under anti-programmed-death protein-1 or its ligand (PD-1/PD-L1).

Heterogeneity of mutational mechanisms and modes of inheritance in auriculocondylar syndrome.

Background: Auriculocondylar syndrome (ACS) is a rare craniofacial disorder consisting of micrognathia, mandibular condyle hypoplasia and a specific malformation of the ear at the junction between the lobe and helix. Missense heterozygous mutations in the phospholipase C, β 4 (PLCB4) and guanine nucleotide binding protein (G protein), α inhibiting activity polypeptide 3 (GNAI3) genes have recently been identified in ACS patients by exome sequencing. These genes are predicted to function within the G protein-coupled endothelin receptor pathway during craniofacial development.
