Molecular typing of Candida albicans isolates from patients and health care workers in a neonatal intensive care unit

2011

Aims:  The aim of this study was to investigate the genetic relatedness between Candida albicans isolates and to assess their nosocomial origin and the likeliness of cross-transmission between health care workers (HCWs) and hospitalized neonates in a neonatal intensive care unit (NICU). Methods:  We retrospectively analysed 82 isolates obtained from 40 neonates and seven isolates from onychomycosis of the fingers of five HCWs in a Tunisian NICU by using pulsed-field gel electrophoresis (PFGE) and randomly amplified polymorphic DNA (RAPD) analysis with CA1 and CA2 as primers. Results:  In RAPD analysis, the discriminatory power (DP) of CA1 and CA2 primers was 0·86 and 0·81, respectively. A h…

Early Effects of Sacubitril/Valsartan on Exercise Tolerance in Patients with Heart Failure with Reduced Ejection Fraction.

2019

Background. Sacubitril/valsartan in heart failure (HF) with reduced ejection fraction (HFrEF) was shown to be superior to enalapril in reducing the risk of death and hospitalization for HF. Our aim was to evaluate the cardiopulmonary effects of sacubitril/valsartan in patients with HFrEF. Methods. We conducted an observational study. Ninety-nine ambulatory patients with HFrEF underwent serial cardiopulmonary exercise tests (CPET) after initiation of sacubitril/valsartan in addition to recommended therapy. Results. At baseline, 37% of patients had New York Heart Association (NYHA) class III. After a median follow-up of 6.2 months (range 3&ndash

Effect of gender and obesity on electrical current thresholds

2011

Introduction: In this study we investigated the influence of gender and obesity on electrical current thresholds in an attempt to optimize the application of skeletal muscle electrical stimulation (ES) in clinical practice. Methods: Thirty- two obese and 35 age-matched, non-obese men and women received graded ES to the quadriceps muscle for sensory (detection) and motor (contraction) threshold assessment. Con- comitant pain and tolerance to ES were recorded. Results: Sen- sory threshold was lower in women than in men (P < 0.001), both obese and non-obese. Sensory and motor thresholds were higher in obese than in non-obese subjects (P < 0.05), and body mass index was a strong predictor of mo…

Anxiety, depression, chronic inflammation and aortic stiffness in Crohn's disease: the brain--gut--vascular axis.

2020

Background Patients with Crohn's disease have an increased aortic stiffness, a known cardiovascular risk factor. Anxiety, a key factor of the brain--gut axis in patients with Crohn's disease, is implicated in the pathogenesis and progression of the disease, and is linked with aortic stiffening in other clinical settings. Objectives Considering that depression is frequently linked to anxiety in Crohn's disease, we performed a mediation analysis to reveal the potential link between anxiety, depression and aortic stiffness in these patients. Methods Multicentre observational cross-sectional study of 86 consecutive patients with Crohn's disease and 86 matched control individuals. The connection…

Peripheral Intravenous Access in Preterm Neonates during Postnatal Stabilization: Feasibility and Safety

2017

Background Current European Guideline for resuscitation recommends a centrally positioned umbilical venous catheter as the best option for administering necessary drugs. Especially in preterm infants, a frequently used alternative is the peripheral venous catheter. Methods Two randomized controlled studies were conducted at the Division of Neonatology, Medical University of Graz. During neonatal resuscitation, a standardized protocol was filled out by an uninvolved observer including time points after birth of all attempts of venous puncture, time point of successful venous puncture, and total number of needed attempts. Arterial oxygen saturation (SpO2) and heart rate (HR) were measured usi…

Endothelial function, adipokine serum levels and white matter hyperintesities in subjects with diabetic foot syndrome.

2019

Abstract Context No study has analyzed the prevalence of white matter hyperintensities (WMHs) in subjects with diabetic foot syndrome (DFS) and their relationship to adipokine serum levels and indexes of endothelial and cognitive performance. Objective To evaluate omentin and vaspin serum levels and the prevalence of WMHs in subjects with DFS and to analyze their relationship with other endothelial, arterial stiffness, and cognitive functions. Design Case-control study enrolling 40 subjects with DFS, 40 diabetic subjects without foot complications, 40 controls with foot lesions without diabetes, and 40 patients without diabetes mellitus. Main Outcome Measures Pulse wave velocity (PWV), augm…

Inflammation and Aortic Stiffness: An Individual Participant Data Meta‐Analysis in Patients With Inflammatory Bowel Disease

2017

Background The recent finding that aortic pulse wave velocity ( aPWV ) is increased in patients with inflammatory bowel disease may explain why the cardiovascular risk is increased despite the low prevalence of traditional cardiovascular risk factors. We aimed to test whether inflammation is associated with aortic stiffening in this setting after adjustment for major confounders and to perform subgroup analyses. Methods and Results A systematic literature search for aPWV in inflammatory bowel disease was performed using PubMed, Scopus, Web of Science, and Google Scholar databases (last accessed May 7, 2017). Inclusion criterion was peer‐reviewed publications on clinical studies reporting o…

Cardiovascular magnetic resonance-derived aortic compliance, distensibility and pulse wave velocity at rest and during a supine bicycle exercise in y…

2014

Background Purpose: Risk of aortic rupture is evaluated based on the vessel diameter; this parameter is probably insufficient. In vivo evaluation of biomechanical property of the aortic tissue might be of interest to discriminate between normal and altered aortic tissue (A Lalande et al, JMRI 2008). The purpose of this study was to describe a technique to measure regional aortic compliance (AC), aortic distensibility (AD) and aortic stiffness with 1.5 T MRI in young individuals under resting conditions and during supine bicycle exercise.
