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…

Nonroutine Use of Intra-Aortic Balloon Pump in Cardiogenic Shock Complicating Myocardial Infarction With Successful and Unsuccessful Primary Percutan…

2018

Abstract Objectives The authors sought to compare outcomes of patients with myocardial infarction and cardiogenic shock (CS) treated with percutaneous coronary intervention (PCI) with or without intra-aortic balloon pump (IABP) support according to final epicardial flow in the infarct-related artery. Background A routine use of IABP is contraindicated in patients with myocardial infarction and CS. There are no data regarding the subpopulation of patients who may benefit from such support besides patients with mechanical complications of myocardial infarction. Methods Prospective nationwide registry data of patients with myocardial infarction and CS treated with PCI between 2003 and 2014 wer…

Vasodilator Stress CMR and All-Cause Mortality in Stable Ischemic Heart Disease

2020

Abstract Objectives This study explored the association of ischemic burden, as measured by vasodilator stress cardiovascular magnetic resonance (CMR), with all-cause mortality and the effect of revascularization on all-cause mortality in patients with stable ischemic heart disease (SIHD). Background In patients with SIHD, the association of ischemic burden, derived from vasodilator stress CMR, with all-cause mortality and its role for decision-making is unclear. Methods The registry consisted of 6,389 consecutive patients (mean age: 65 ± 12 years; 38% women) who underwent vasodilator stress CMR for known or suspected SIHD. The ischemic burden (at stress first-pass perfusion imaging) was com…

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…

Treatment of early childhood medulloblastoma by postoperative chemotherapy alone.

2005

The prognosis for young children with medulloblastoma is poor, and survivors are at high risk for cognitive deficits. We conducted a trial of the treatment of this brain tumor by intensive postoperative chemotherapy alone.After surgery, children received three cycles of intravenous chemotherapy (cyclophosphamide, vincristine, methotrexate, carboplatin, and etoposide) and intraventricular methotrexate. Treatment was terminated if a complete remission was achieved. Leukoencephalopathy and cognitive deficits were evaluated.Forty-three children were treated according to protocol. In children who had complete resection (17 patients), residual tumor (14), and macroscopic metastases (12), the five…

The relevance of depressive symptoms for the outcome of patients receiving vitamin K antagonists: results from the thrombEVAL cohort study.

2020

Abstract Aims Although depressive symptoms are highly prevalent in patients receiving oral anticoagulation (OAC), the relevance of depression for the outcome of anticoagulated individuals is unknown. Methods and results We analysed data from the multicentre cohort study thrombEVAL (NCT01809015) investigating the efficacy of OAC with vitamin K antagonists. There was an independent study monitoring, and an independent review panel assessed the endpoints. Out of n = 1558 participants, information about depressive symptoms, as measured by the two-item screener of the patient health questionnaire (PHQ-2), was available in n = 1405 individuals. The mean follow-up period was 28.04 months, with a s…

Central Obesity and Survival in Subjects With Coronary Artery Disease

2011

Objectives The aim of this study was to examine the association of central (waist circumference [WC] and waist-hip ratio [WHR]) and total obesity (body mass index [BMI]) measures with mortality in coronary artery disease (CAD) patients. Background The question of which measure of obesity better predicts survival in patients with CAD is controversial. Methods We searched OVID/Medline, EMBASE, CENTRAL, and Web of Science from 1980 to 2008 and asked experts in the field for unpublished data meeting inclusion criteria, in which all subjects had: 1) CAD at baseline; 2) measures of WC or WHR; 3) mortality data; and 4) a minimum follow-up of 6 months. Results From 2,188 studies found, 6 met inclus…

Weight loss in Alzheimer’s disease, vascular dementia and dementia with Lewy bodies: Impact on mortality and hospitalization by dementia subtype

2021

Objectives Loss of weight is associated with cognitive decline as well as several adverse outcomes in dementia. The aim of this study was to assess whether weight loss is associated with mortality and hospitalization in dementia subtypes. Methods A cohort of 11,607 patients with dementia in Alzheimer's disease (AD), vascular dementia (VD), or dementia with Lewy bodies (DLB) was assembled from a large dementia care health records database in Southeast London. A natural language processing algorithm was developed to established whether loss of weight was recorded around the time of dementia diagnosis. Cox proportional hazard models were applied to examine the associations of reported weight l…
