A score model for the continuous grading of early allograft dysfunction severity

2014

Early allograft dysfunction (EAD) dramatically influences graft and patient outcomes. A lack of consensus on an EAD definition hinders comparisons of liver transplant outcomes and management of recipients among and within centers. We sought to develop a model for the quantitative assessment of early allograft function [Model for Early Allograft Function Scoring (MEAF)] after transplantation. A retrospective study including 1026 consecutive liver transplants was performed for MEAF score development. Multivariate data analysis was used to select a small number of postoperative variables that adequately describe EAD. Then, the distribution of these variables was mathematically modeled to assig…

Abstract 412: The Sodium-Glucose Cotransporter 2 Inhibitor Empagliflozin Improves Diabetic Complications in the Streptozotocin Type 1 Diabetes Mellit…

2014

Objectives: In diabetes, cardiovascular complications are associated with endothelial dysfunction and oxidative stress. Empagliflozin (Empa), as a selective sodium-glucose co-transporter 2 inhibitor (SGLT2i) in clinical development, offers a promising novel approach for the treatment of type 2 diabetes by enhancing urinary glucose excretion. The aim of the present study was to test whether treatment with Empa could improve endothelial dysfunction in type I diabetic rats via reduction of glucotoxicity and associated oxidative stress. Research Design and Methods: Type I diabetes in Wistar rats was induced by an intravenous injection of streptozotocin (60 mg/kg). One week after injection Empa…

Objective: Radical prostatectomy (RP) is a frequent treatment for men suffering from localized prostate cancer (PCa). Whilst offering a high chance for cure, it does not come without a significant impact on health-related quality of life. Herein we review the common adverse effects RP may have over the course of time.Methods: A collaborative narrative review was performed with the identification of the principal studies on the topic. The search was executed by a relevant term search on PubMed from 2010 to February 2021.Results: Rates of major complications in patients undergoing RP are generally low. The main adverse effects are erectile dysfunction varying from 11 to 87% and urinary incont…

Safety of agalsidase alfa in patients with Fabry disease under 7 years

2011

Aim:  To evaluate the safety and explore the efficacy of enzyme replacement therapy (ERT) for Fabry disease with agalsidase alfa in young children enrolled in the Fabry Outcome Survey (FOS). Methods:  This retrospective chart review identified eight children (mean age = 5.0 ± 1.6 [mean ± SD]) in FOS who began treatment with agalsidase alfa (0.2 mg/kg, i.v., every other week) when <7 years old. Vital signs and adverse events were monitored throughout the study period. Glomerular filtration rate (GFR) was estimated, and left ventricular mass indexed to height2.7 (LVMi) was assessed with echocardiography. Patients received 1.2–6.7 years of treatment (mean = 4.2 years). Results:  Infusion react…

Transpenile Venenokklusion zur Therapie der erektilen Impotenz

1989

In 15 of 18 patients, 2 of them with previous surgery, transpenile venoablation was performed for treatment of erectile dysfunction due to cavernous leakage. In 4 this was combined with retrograde venooclusion via the internal iliac vein. In 4 patients normal erectile status could be obtained. In 3 other patients erections became possible with use of intracavernous vasoactive agents. In two only mild amelioration, and in two others no change of erectile dysfunction were obtained. Follow-up studies are yet missing in 3 patients. Complications of the procedure were not observed.

Right ventricular function and iron deficiency in acute heart failure

2021

Abstract Aims Iron deficiency (ID) is a frequent finding in patients with chronic and acute heart failure (AHF) along the full spectrum of left ventricular ejection fraction (LVEF). Iron deficiency has been related to ventricular systolic dysfunction, but its role in right ventricular function has not been evaluated. We sought to evaluate whether ID identifies patients with greater right ventricular dysfunction in the setting of AHF. Methods and results We prospectively included 903 patients admitted with AHF. Right systolic function was evaluated by tricuspid annular plane systolic excursion (TAPSE) and the ratio TAPSE/pulmonary artery systolic pressure (TAPSE/PASP). Iron deficiency was de…

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…

Right Heart Dysfunction and Readmission Risk Across Left Ventricular Ejection Fraction Status in Patients With Acute Heart Failure.

2021

BACKGROUND: Right heart dysfunction (RHD) parameters are increasingly important in heart failure (HF). This study aimed to evaluate the association of advanced RHD with the risk of recurrent admissions across the spectrum of left ventricular ejection fraction (LVEF). METHODS AND RESULTS: We included 3383 consecutive patients discharged for acute HF. Of them, in 1435 patients (42.4%), the pulmonary artery systolic pressure could not be measured accurately, leaving a final sample size of 1948 patients. Advanced RHD was defined as the combination of a ratio of tricuspid annular plane systolic excursion/pulmonary artery systolic pressure of less than 0.36 and significant tricuspid regurgitation…

Defining right ventricular dysfunction by the use of echocardiography in normotensive patients with pulmonary embolism

2020

Although the prognostic value of various echocardiographic parameters of right ventricular dysfunction (RVD) was reported in normotensive patients with acute pulmonary embolism (PE), there is no generally accepted definition of RVD.The aim of the study was to compare echocardiographic parameters for the prediction of an adverse 30‑day outcome and create an optimal definition of RVD.                                     Patients and methods: Echocardiographic parameters including the right ventricular to left ventricular diameter ratio (RV to LV ratio) and tricuspid annular plane systolic excursion (TAPSE) to predict PE‑related mortality, hemodynamic collapse, or rescue thrombolysis within th…

Application of Supervised Machine Learning for Behavioral Biomarkers of Autism Spectrum Disorder Based on Electrodermal Activity and Virtual Reality

2020

[EN] Objective: Sensory processing is the ability to capture, elaborate, and integrate information through the five senses and is impaired in over 90% of children with autism spectrum disorder (ASD). The ASD population shows hyper¿hypo sensitiveness to sensory stimuli that can generate alteration in information processing, affecting cognitive and social responses to daily life situations. Structured and semi-structured interviews are generally used for ASD assessment, and the evaluation relies on the examiner¿s subjectivity and expertise, which can lead to misleading outcomes. Recently, there has been a growing need for more objective, reliable, and valid diagnostic measures, such as biomar…
