iScore for predicting institutional care after ischemic stroke: a population-based study.
2015
Background We assessed whether the iScore could predict the need for poststroke institutional care. Methods Patients with acute ischemic stroke living in Dijon, France, were recorded between 2006 and 2011, using a population-based stroke registry. The iScore was calculated for each patient. A logistic regression model was used to assess the performance of the iScore for predicting the need for placement in a care institution. The discrimination and calibration of the model were assessed using the c statistic and the Hosmer–Lemeshow goodness-of-fit test, respectively. Results Of the 1199 patients recorded, 124 were excluded because of early death and 95 because of missing for variables inclu…
Impact of coronary calcium score on diagnostic accuracy for the detection of significant coronary stenosis with multislice computed tomography angiog…
2005
One hundred twenty patients in sinus rhythm with suspected coronary artery disease who underwent multislice computed tomography of the heart and conventional coronary angiography were retrospectively selected. The population was divided into 2 groups depending on their calcium score (CS) (e.g., low CS and high CS). The diagnostic accuracy of multislice computed tomographic scans for detecting significant lesions (>50% lumen reduction) in both groups was compared with quantitative coronary angiography. The sensitivity and specificity of multislice computed tomography were 90% and 92%, and 97% and 91% for low and high CS groups, respectively.
Indications for preoperative prostate biopsy in patients undergoing radical cystoprostatectomy for bladder cancer.
2008
We determined indications for preoperative prostate biopsy in patients undergoing radical cystoprostatectomy for bladder cancer.Of 316 cystoprostatectomy specimens concomitant prostate cancer was diagnosed in 21.5%. Prostate cancer was diagnosed preoperatively in 24% of cases (evident prostate cancer), 32% were suspicious for prostate cancer but no biopsy was done (suspected prostate cancer) and in 44% prostate cancer was incidental. Patients were stratified into probability groups of intermediate/high risk prostate cancer by digital rectal examination and prostate specific antigen. The incidence of unfavorable histopathology was determined in each group.Of prostate cancers 85% were organ c…
Differences in axial segment reorientation during standing turns predict multiple falls in older adults
2011
Author's version of an article in the journal: Gait and Posture. Also available from the publisher at: http://dx.doi.org/10.1016/j.gaitpost.2012.05.013 Background: The assessment of standing turning performance is proposed to predict fall risk in older adults. This study investigated differences in segmental coordination during a 360° standing turn task between older community-dwelling fallers and non-fallers. Methods: Thirty-five older adults age mean (SD) of 71 (5.4) years performed 360° standing turns. Head, trunk and pelvis position relative to the laboratory and each other were recorded using a Vicon motion analysis system. Fall incidence was monitored by monthly questionnaire over the…
Designing a new scoring system (QualyP Score) correlating the management of cardiopulmonary bypass to postoperative outcomes
2014
Aim: The aim of this study was to ascertain if a score, directly derived from CPB records, could correlate to major postoperative outcomes. Methods: An additive score (QualyP Score) was created from 10 parameters: peak lactate value during CPB, peak VCO2i, lowest DO2i/VCO2i, peak respiratory quotient, CPB time, cross-clamp time, lowest CPB temperature, circulatory arrest, ultrafiltration during CPB, number of packed red cells transfused intraoperatively. The PerfSCORE was calculated, as well. Multivariable logistic regression models were built to detect the independent predictors of: peak lactate >3 mmol/L during the first three postoperative days; the incidence of acute kidney injury ne…
Assessment of hepatitis C virus-RNA clearance under combination therapy for hepatitis C virus genotype 1: performance of transcription-mediated ampli…
2007
Monitoring of HCV-RNA in blood during antiviral therapy is performed mostly by commercially available reverse transcription polymerase chain reaction-based (RT-PCR) assays, with a lower detection limit of 30-50 IU/mL of HCV-RNA. Use of different tests in the pivotal trials of combination therapy has generated some discordance, in terms of predictive value of the early virological response (EVR). To evaluate whether the use of a more sensitive test, as a qualitative assay based on transcription mediated amplification (TMA) with a lower detection limit of 5-10 IU/mL of HCV-RNA, may obtain a better prediction of EVR and of the ultimate virological outcome, we retrospectively evaluated serial s…
Heart rate variability in sick sinus syndrome: does it have a diagnostic role?
2019
BACKGROUND: Hypothesis of our study was that the irregular rhythm of sick sinus syndrome (SSS) was characterized by an augmented HRV. Objective was to assess whether SSS patients had a typical HRV profile. METHODS: We screened all 1947 consecutive Holter ECGs performed in our Units of Vascular Medicine and Internal Medicine and Cardioangiology at the University of Palermo (Italy) from April 2010 to September 2014. Among these, we selected 30 patients with ECG criteria of SSS. They were compared to 30 patients without SSS matched for age, sex and comorbidities. RESULTS: The SSS group had a lower mean heart rate (HR) (P=0.003), and a longer mean NN max-min longer (P<0.0005) compared to con…
The predictive role of C-reactive protein in patients with hypertension and subclinical atherosclerosis.
2009
Recent guidelines published by the joint European Society of Hypertension/European Society of Cardiology have suggested the inclusion of C-reactive protein (CRP) in the standard assessment of cardiovascular risk in hypertensive patients, but little data is available on the role of CRP in patients with carotid lesions. We studied in 472 subjects, 236 with and 236 without hypertension, gender- and age-matched, with and without early stages of atherosclerosis (e.g. those with asymptomatic intima-media thickness >0.9 mm), the influence of all the other traditional cardiovascular risk factors (e.g. older age, male gender, obesity, diabetes, smoking habit, family history of coronary artery diseas…
Sentinel lymph node biopsy in malignant melanoma of the head and neck
2018
Abstract Background The aim of this retrospective study was to investigate sentinel lymph node biopsy in patients with head and neck melanoma. Materials and methods Patients who underwent SLNB between 2010 and 2016 were comprised. Epidemiological, radiological, and surgical data were collected and compared to histological findings. Patients who underwent primary complete lymph node dissection were excluded. Results 74 patients underwent SLNB during this period. The most common tumor localizations were the cheek (20.4%) and ears (20.4%). Overall, 256 sentinel lymph nodes (SLN) were detected and removed, most frequently in Robbins-levels IIA and IIB as well as in the surrounding of the paroti…
Three-Dimensional Analysis of Component Stability of the Nellix Endovascular Aneurysm Sealing System After Treatment of Infrarenal Abdominal Aortic A…
2016
Purpose: To assess short-term stability and conformational changes of the Nellix EndoVascular Aneurysm Sealing (EVAS) System using 3-dimensional (3D) analysis. Methods: Postoperative computed tomography (CT) scans obtained at 0, 3, and 12 months in 24 patients (mean age 75±7 years; 22 men) who underwent EVAS between December 2013 and December 2014 for intact abdominal aortic aneurysm (within the instructions for use) were evaluated for stent-graft deviation in multiple planes using dedicated 3D analysis software. In addition, 2D analysis using an anatomically fixed reference landmark was performed to assess craniocaudal migration. Clinical and follow-up data of the patients were recorded a…
