Prognostic implications of dipyridamole cardiac MR imaging: a prospective multicenter registry
2011
Purpose: To evaluate dipyridamole cardiac magnetic resonance (MR) imaging in the prediction of major events (MEs) in patients with ischemic chest pain in a large multicenter registry. Materials and Methods: Institutional ethics committee approval and written informed consent were obtained. A total of 1722 patients who were undergoing cardiac MR imaging for chest pain were included. Wall motion abnormalities (WMAs) at rest, hyperemia perfusion defect (PD), late gadolinium enhancement (LGE), and inducible WMA were analyzed (abnormal if more than one abnormal segment was seen) with the 17-segment model. A cardiac MR categorization was created: category 1, no PD, LGE, or inducible WMA; category…
Usefulness of a Comprehensive Cardiovascular Magnetic Resonance Imaging Assessment for Predicting Recovery of Left Ventricular Wall Motion in the Set…
2005
ObjectivesWe sought to evaluate the usefulness of a comprehensive assessment of four cardiovascular magnetic resonance imaging (CMR)-derived myocardial viability indexes in the setting of myocardial stunning.BackgroundCardiovascular magnetic resonance imaging allows the simultaneous assessment of several viability indexes.MethodsWe studied 40 patients with a first ST-segment elevation myocardial infarction (MI) and an open infarct-related artery. At the first week, using CMR, wall motion (WM), and four viability indexes were determined: wall thickness, WM improvement with low-dose dobutamine, perfusion, and transmural extent of necrosis. We created a comprehensive score based on the presenc…
Cholesteryl ester transfer protein activity and cardiovascular events in patients with chronic kidney disease stage V.
2008
Background Patients with chronic kidney disease (CKD) have an increased risk for cardiovascular events (CVE). Uraemic dyslipidaemia, which is characterized by low HDL-cholesterol (HDL-C) and elevated triglycerides' levels, may contribute to this elevated cardiovascular risk. Cholesteryl ester transfer protein (CETP) lowers HDL-C by transferring cholesterol esters to LDL and VLDL particles. We tested the hypothesis that CETP activity is associated with CVE in patients with CKD stage V. Methods We measured CETP activity and cholesterol levels in 69 haemodialysis patients. CVE and death were prospectively assessed over a follow-up period of 48 months. Results CETP activity was negatively corre…
Expression of transketolase TKTL1 predicts colon and urothelial cancer patient survival: Warburg effect reinterpreted
2006
Abstract Tumours ferment glucose to lactate even in the presence of oxygen (aerobic glycolysis; Warburg effect). The pentose phosphate pathway (PPP) allows glucose conversion to ribose for nucleic acid synthesis and glucose degradation to lactate. The nonoxidative part of the PPP is controlled by transketolase enzyme reactions. We have detected upregulation of a mutated transketolase transcript (TKTL1) in human malignancies, whereas transketolase (TKT) and transketolase-like-2 (TKTL2) transcripts were not upregulated. Strong TKTL1 protein expression was correlated to invasive colon and urothelial tumours and to poor patients outcome. TKTL1 encodes a transketolase with unusual enzymatic prop…
Amyotrophic lateral sclerosis outcome measures and the role of albumin and creatinine: a population-based study.
2014
Importance There is an urgent need to identify reliable biomarkers of amyotrophic lateral sclerosis (ALS) progression for clinical practice and pharmacological trials. Objectives To correlate several hematological markers evaluated at diagnosis with ALS outcome in a population-based series of patients (discovery cohort) and replicate the findings in an independent validation cohort from an ALS tertiary center. Design, Setting, and Participants The discovery cohort included 712 patients with ALS from the Piemonte and Valle d’Aosta Register for Amyotrophic Lateral Sclerosis from January 1, 2007, to December 31, 2011. The validation cohort comprised 122 patients with ALS at different stages of…
A New Prognosis Score to Predict Mortality After Acute Pneumonia in Very Elderly Patients
2016
International audience; Objectives: Acute pneumonia (AP) induces an excess of mortality among the elderly. We evaluated the value of a new predictive biomarker index compared to usual prognosis scores for predicting in-hospital and 1-year mortalities in elderly inpatients with AP.Design: Retrospective study in 6 clinical departments of a university hospital.Setting: Burgundy university hospital (France).Participants: All patients aged 75 and over with AP and hospitalized between January 1 and June 30, 2013, in the departments of medicine (5) and intensive care (1) of our university hospital.Measurements: A new index, which we named UBMo, was created by multiplying the uremia (U in the formu…
Using the Hemophilia Joint Health Score for assessment of children: Reliability of the Spanish version
2018
Introduction: Numerous measuring instruments for the evaluation of hemophilic arthropathy have been developed. One of the most used systems is the Hemophilia Joint Health Score (HJHS) given its sensitivity to clinical changes appearing in the joints because of recurrent hemarthrosis. Objective: Assessing the interrater reliability, using the Spanish version of the HJHS (version 2.1) in children with hemophilia. Design: Reliability study to assess the interrater reliability of the Spanish version of HJHS. Methods: A sample of 36 children aged 7–13 years diagnosed with hemophilia A or B was used. Two physiotherapists performed physical assessments with the Spanish version of the HJHS. Descrip…
A contemporary assessment of nocturia: definition, epidemiology, pathophysiology, and management--a systematic review and meta-analysis
2012
Abstract Context Nocturia is a common urologic symptom that has been covered in a variety of reported studies in the literature but is not specifically covered in current guidelines. Objective To comprehensively review the literature pertaining to the definition, etiologies, and consequences of nocturia and assess the evidence supporting the use of conservative medical and interventional therapy. Evidence acquisition A literature search was conducted using the keyword nocturia , restricted to articles in the English language, after 2000 and before April 2012, in PubMed/Medline, Embase, Scopus, Web of Science, and Cochrane Library databases. Regarding treatment modalities, studies were inclu…
Simultaneous determination in situ of DNA fragmentation and 8-oxoguanine in human sperm.
2009
Deoxyribonucleic acid fragmentation and oxidative DNA damage were simultaneously determined in the same sperm cell, incubating with an 8-oxoguanine DNA probe on human spermatozoa processed by the sperm chromatin dispersion test. The assay was validated by incubation with agents that induce DNA fragmentation with or without oxidative base damage. In all samples examined, increased levels of 8-oxoguanine were present only in those spermatozoa with fragmented DNA, suggesting a link between both DNA damage types.
The temporal association between executive function and life-space mobility in old age
2018
Background Life-space mobility, an indicator of community mobility, describes person’s movements in terms of the distance from home, the frequency of movement, and the need of assistance for movement. Executive function (EF) is a higher-order cognitive function that supervises motor control and plays a key role in a person’s ability to function independently. Cognitive impairment often co-occurs with restricted life-space mobility; however, the direction of the longitudinal associations between EF and life-space mobility is unclear. The aim of this study was to investigate the temporal associations between EF and life-space mobility among community-dwelling older people. Methods One hundred…
