Long-Term Follow-Up of Repeat Endoscopic Third Ventriculostomy in Obstructive Hydrocephalus.
2017
Endoscopic third ventriculostomy (ETV) is a safe and less-invasive treatment strategy for patients with obstructive hydrocephalus and provides excellent outcome. Nevertheless, repeat ETV in cases of ETV failure is a controversial issue.Between 1993 and 1999, 113 patients underwent a total of 126 ETVs at the Department of Neurosurgery, Mainz University Hospital. Obstructive hydrocephalus was the causative pathology in all cases. A very long-term follow-up of up to 16 years could be achieved. All medical reports of patients who received ETV were reviewed and analyzed with focus on ETV failure with following repeat ETV and its initial as well as very long-term success.Thirty-one events of ETV …
Endovascular Aneurysm Sealing (EVAS) and Chimney EVAS in the Treatment of Failed Endovascular Aneurysm Repairs
2016
Purpose: To assess the technical success and clinical outcome of reinterventions using the Nellix Endovascular Aneurysm Sealing (EVAS) System to treat complications after endovascular aneurysm repair (EVAR). Methods: Fifteen consecutive patients (mean age 79 years; 14 men) with prior EVAR were treated with EVAS between March 2014 and December 2015 at 2 institutions. The failed prior EVARs included 13 bifurcated endografts, 1 bifurcated graft plus fenestrated cuff, and 1 tube endograft. Endoleaks were the predominant indications: type Ia in 10 and type III in 5 (3 type IIIa and 2 type IIIb). All patients presented with progressive aortic aneurysms (median 7.85-cm diameter; range 6.5–11). Ei…
Liver transplantation with grafts from septuagenarians.
2008
Abstract Background The purpose of this study was to evaluate our experience with orthotopic liver transplantation (OLT) using grafts from septuagenarians. Patients and Methods Seventeen adult patients underwent transplantation with grafts from donors 70 years of age or older during an 8-year period. Results The median donor age was 73 years (range, 70–83). Eleven (64.7%) donors had experienced at least 1 hypotensive period and received vasoactive drugs. Median cold and warm ischemia times were 7.25 hours and 35 minutes, respectively. Two recipients underwent retransplantation because of dysfunction or primary nonfunction. Morbidity rate was 47% and hospital mortality rate was 23.5%. After …
Prognostic Implications of Tissue Doppler Imaging-Derived E/Ea Ratio in Acute Heart Failure Patients
2014
Background Tissue Doppler–derived transmitral to mitral annular early diastolic velocity ratio (E/Ea), as a noninvasive estimation of left ventricular (LV) filling pressures, is a strong prognosticator in various cardiac scenarios including chronic heart failure; nevertheless, its utility for risk stratification in the whole spectrum of acute heart failure (AHF) patients remains elusive. Thus, the aim of this study was to determine the association between E/Ea ratio and 1-year mortality in nonselected patients with AHF. Methods The study included 417 consecutive patients admitted for AHF. Twenty-two patients were excluded due to nonaccurate Ea measurements, leaving the final sample to be 39…
Usefulness of Right Ventricular to Pulmonary Circulation Coupling as an Indicator of Risk for Recurrent Admissions in Heart Failure With Preserved Ej…
2019
In recent years, the study of right ventricular (RV) to pulmonary circulation (PC) coupling in heart failure with preserved ejection fraction (HFpEF) has been a matter of special interest. Tricuspid annular plane systolic excursion (TAPSE) to pulmonary artery systolic pressure (PASP) ratio has emerged as a reliable noninvasive index of RV to PC coupling. Thus, we hypothesized that TAPSE/PASP would be a predictor of readmission burden in HFpEF. One thousand one hundred and twenty seven consecutive HFpEF patients discharged for acute HF were included. In 367 patients (32.6%), PASP could not be accurately measured by echocardiography, leaving the final sample size to be 760 patients. Negative …
Ejection Fraction by Echocardiography for a Selective Use of Magnetic Resonance After Infarction
2020
[EN] Background Cardiac magnetic resonance (CMR) permits robust risk stratification of discharged ST-segment-elevation myocardial infarction patients, but its indiscriminate use in all cases is not feasible. We evaluated the utility of left ventricular ejection fraction (LVEF) by echocardiography for a selective use of CMR after ST-segment-elevation myocardial infarction. Methods Echocardiography and CMR were performed in 1119 patients discharged for ST-segment-elevation myocardial infarction included in a multicenter registry. The prognostic power of CMR beyond echocardiography-LVEF was assessed using adjusted C statistic, net reclassification improvement index, and integrated discriminati…
Cardiovascular Efficacy and Safety of Bococizumab in High-Risk Patients
2017
Item does not contain fulltext BACKGROUND: Bococizumab is a humanized monoclonal antibody that inhibits proprotein convertase subtilisin-kexin type 9 (PCSK9) and reduces levels of low-density lipoprotein (LDL) cholesterol. We sought to evaluate the efficacy of bococizumab in patients at high cardiovascular risk. METHODS: In two parallel, multinational trials with different entry criteria for LDL cholesterol levels, we randomly assigned the 27,438 patients in the combined trials to receive bococizumab (at a dose of 150 mg) subcutaneously every 2 weeks or placebo. The primary end point was nonfatal myocardial infarction, nonfatal stroke, hospitalization for unstable angina requiring urgent re…
Fetuin-A serum levels are not correlated to kidney function in long-lived subjects
2012
Objectives: Serum Fetuin A has been identified as an inhibitor of ectopic calcification. It is reduced in subjects with chronic kidney disease (CKD) and it has been proposed as a potential link between CKD and the higher prevalence of arterial calcification observed in these patients. During ageing both the stiffening of arterial wall due to calcification and a decline in kidney function are frequent. The aim of the study is to investigate if Fetuin A serum levels are associated with ageing and with AHSG T256S polymorphism. Moreover, we aim at investigate whether serum Fetuin A is correlated to kidney function in this setting of senescence. Design and Methods: 256 health long-lived subjects…
Effectiveness of assisted and unassisted cough capacity in amyotrophic lateral sclerosis patients.
2017
Decreased cough capacity during a respiratory infection is one of the main causes of acute respiratory failure and hospitalisation in amyotrophic lateral sclerosis (ALS).To determine whether a respiratory measurement could identify the effectiveness of cough capacity in ALS during a respiratory infection.This was a prospective study of all ALS patients who were treated at a respiratory care unit due to a respiratory infection from 2012 to 2016. The effectiveness of unassisted and assisted coughing was evaluated and respiratory function tests were performed during the acute episode.Forty-eight ALS patients were enrolled, with only four having an effective unassisted cough. The variable which…
Liraglutide and Renal Outcomes in Type 2 Diabetes.
2017
BACKGROUND: In a randomized, controlled trial that compared liraglutide, a glucagon-like peptide 1 analogue, with placebo in patients with type 2 diabetes and high cardiovascular risk who were receiving usual care, we found that liraglutide resulted in lower risks of the primary end point (nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes) and death. However, the long-term effects of liraglutide on renal outcomes in patients with type 2 diabetes are unknown. METHODS: We report the prespecified secondary renal outcomes of that randomized, controlled trial in which patients were assigned to receive liraglutide or placebo. The secondary renal outcome was a co…
