Sudden cardiac death due to anomalous origin of the right coronary artery: A case report in a child

2006

Potential role of the neuropeptide CGRP in the induction of differentiation of rat hepatic portal vein wall.

2005

The media of the rat hepatic portal vein is composed of an internal circular muscular layer (CL) and an external longitudinal muscular layer (LL). These two perpendicular layers differentiate progressively from mesenchymal cells within the first month after birth. In this paper, we studied the development of calcitonin gene-related peptide (CGRP) innervation during post-natal differentiation of the vessel. We show that CGRP innervation is already present around the vessel at birth in the future adventitia but far from the lumen of the vessel. Progressively, CGRP immunoreactive fibers reached first LL then CL. CL by itself become only innervated at day 14 after birth. This corresponds to the…

Insulin resistance aggravates atherosclerosis by reducing vascular smooth muscle cell survival and increasing CX3CL1/CX3CR1 axis.

2014

Aims Insulin resistance (IR) is a major risk factor for cardiovascular disease and atherosclerosis. Life-threatening acute events are mainly due to rupture of unstable plaques, and the role of vascular smooth muscle cells (VSMCs) in this process in IR, Type 2 diabetes mellitus, and metabolic syndrome (T2DM/MetS) has not been fully addressed. Therefore, the role of VSMC survival in the generation of unstable plaques in T2DM/MetS and the involvement of inflammatory mediators was investigated. Methods and results Defective insulin receptor substrate 2 (IRS2)-mediated signalling produced insulin-resistant VSMCs with reduced survival, migration, and higher apoptosis than control cells. Silencing…

Impact of Residual Mitral Regurgitation on Survival After Transcatheter Edge-to-Edge Repair for Secondary Mitral Regurgitation.

2021

OBJECTIVES The aim of this study was to assess the impact of residual mitral regurgitation (resMR) on mortality with respect to left ventricular dilatation (LV-Dil) or right ventricular dysfunction (RV-Dys) in patients with secondary mitral regurgitation (SMR) who underwent mitral valve transcatheter edge-to-edge repair (TEER). BACKGROUND The presence of LV-Dil and RV-Dys correlates with advanced stages of heart failure in SMR patients, which may impact the outcome after TEER. METHODS SMR patients in a European multicenter registry were evaluated. Investigated outcomes were 2-year all-cause mortality and improvement in New York Heart Association functional class with respect to MR reduction…

Is GH dosing optimal in female patients with adult-onset GH deficiency? An analysis from the NordiNet® International Outcome Study

2017

SummaryObjective To evaluate gender differences in GH dosing, IGF-I and cardiovascular risk markers in adults with GH deficiency (GHD). Design NordiNet® International Outcome Study (NCT00960128), a noninterventional, multicentre study, evaluates the long-term effectiveness and safety of Norditropin® (Novo Nordisk A/S) in the real-life clinical setting. Patients Nondiabetic patients (n = 252; 41·7% female) with adult-onset GHD (age ≥20 years at GH start), ≥4 years’ GH therapy and glycosylated haemoglobin (HbA1c) data at baseline and 4 years. Measurements Effects of gender (adjusted for baseline age and body mass index [BMI], average GH dose, treatment duration and concomitant medication) on …

Grip strength predicts cardiac adverse events in patients with cardiac disorders: an individual patient pooled meta-analysis.

2019

ObjectiveGrip strength is a well-characterised measure of weakness and of poor muscle performance, but there is a lack of consensus on its prognostic implications in terms of cardiac adverse events in patients with cardiac disorders.MethodsArticles were searched in PubMed, Cochrane Library, BioMed Central and EMBASE. The main inclusion criteria were patients with cardiac disorders (ischaemic heart disease, heart failure (HF), cardiomyopathies, valvulopathies, arrhythmias); evaluation of grip strength by handheld dynamometer; and relation between grip strength and outcomes. The endpoints of the study were cardiac death, all-cause mortality, hospital admission for HF, cerebrovascular accident…

Noninvasive Positive Pressure Ventilation in Amyotrophic Lateral Sclerosis

2010

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease of unknown origin that affects approximately 1.5 individuals per 100,000 every year; usually, these individuals are between 55 and 75 years of age [1]. ALS causes progressive weakness of voluntary muscle groups, including respiratory ones, and respiratory failure or pneumonia related to respiratory muscle weakness is the most frequent cause of death.

Modified cryopreservation and xenotransplantation of human parathyroid tissue.

1999

Introduction: A modified cryopreservation technique for human parathyroid tissue was compared with the standard method using a programmed freezer. Methods: Total parathyroidectomy was performed in three groups of 6-week-old Rowett nude rats. Group I (control) underwent no transplantation of parathyroid tissue (n=9). After 10 days, the rats of groups II (n=15) and III (n=15) underwent xenotransplantation of 20 mg cryopreserved human parathyroid tissue, which had been stored in liquid nitrogen at –196°C for 1–22 months prior to xenotransplantation. The parathyroid tissue was derived from 15 parathyroidectomized patients with renal hyperparathyroidism. Two tissue samples were obtained from eve…

Esthesioneuroblastoma presenting with epifora in a young child

1997

Esthesioneuroblastoma (ENB) is an uncommon tumor believed to arise from the olfactory epithelium. 1 This neoplasm has rarely been reported in children, with only 12 cases reported to date among patients younger than 10 years. 2 The usual initial symptom in children, as in older patients, is nasal obstruction or epistaxis 3 ; consequently, the tumor is often first seen by an otorhinolaryngologist. We report a case of ENB in a young child in whom the initial symptom was epiphora; to our knowledge, this initial symptom is previously unreported, and ENB must now be considered in the differential diagnosis of epiphora in childhood. Report of a Case. A white 6-year-old male child was seen on Janu…
