Inflammation, atherosclerotic burden and cardiovascular prognosis.

2006

The aim of this study was to evaluate the impact of various inflammatory markers on atherosclerotic burden and cardiovascular prognosis.In a prospective study 720 patients preceding coronary angiography were enrolled. In all patients carotid and leg arteries were examined using sonographic methods and C-reactive protein, fibrinogen, interleukin-18 (IL-18) and interleukin-6 have been determined. Patients were compared with regard to atherosclerotic burden: no clinically significant stenosis (N=57, 7.9%), coronary artery disease only (N=362, 50.3%), coronary artery disease with peripheral atherosclerosis (=multi-vascular atherosclerosis, N=301, 41.8%).Follow-up data after a median of 6.5 year…

A quality improvement study on the reduction of central venous catheter-associated bloodstream infections by use of self-disinfecting venous access c…

2020

Background Contamination of the catheter hub is an important source of central line-associated bloodstream infections (CLABSI); catheter hub caps incorporating a 70% isopropyl alcohol aim are designed to reduce contamination and hence CLABSI rates. Supporting data in high-risk hematological and oncological patients on the clinical effectiveness of this approach are sparse. Methods We conducted a before-after single center study accompanying the introduction of such caps at our department. Retrospective data from the year prior to the introduction were compared to 1 year of prospective data. Results The control and antiseptic barrier cap (ABC) groups consisted of 309 and 289 patients present…

A Nomogram-Based Prognostic Model for Advanced Hepatocellular Carcinoma Patients Treated with Sorafenib: A Multicenter Study

2021

Simple Summary Accurate prognostic systems capable of predicting the survival of patients with advanced hepatocellular carcinoma undergoing Sorafenib therapy are still lacking. The search for the ideal predictive tool for survival and drug response is justified by the recent availability of several other drugs effective for these patients, licensed as first- and second-line treatment, other than reducing adverse events and costs. In this study, we aimed to identify simple demographic and clinical parameters able to predict survival and Sorafenib response in a large multicenter cohort. In this study, we showed that patient’s general status, liver function and damage laboratory parameters and…

The multidimensional prognostic index (MPI) for the prognostic stratification of older inpatients with COVID-19: A multicenter prospective observatio…

2021

Background: The topic of prognosis in COVID-19 research may be important in adopting appropriate clinical decisions. Multidimensional prognostic index (MPI) is a frailty assessment tool widely used for stratifying prognosis in older people, but data regarding inpatients, affected by COVID-19, are not available. Objectives: To evaluate whether MPI can predict in-hospital mortality and the admission to intensive care unit (ICU) in older inpatients hospitalized for COVID-19 infection. Methods: In this longitudinal, Italian, multi-center study, older patients with COVID-19 were included. MPI was calculated using eight different domains typical of comprehensive geriatric assessment and categoriz…

Association between dietary fibre intake and fruit, vegetable or whole-grain consumption and the risk of CVD: results from the PREvención con DIeta M…

2016

Prospective studies assessing the association between fibre intake or fibre-rich food consumption and the risk of CVD have often been limited by baseline assessment of diet. Thus far, no study has used yearly repeated measurements of dietary changes during follow-up. Moreover, previous studies included healthy and selected participants who did not represent subjects at high cardiovascular risk. We used yearly repeated measurements of diet to investigate the association between fibre intake and CVD in a Mediterranean cohort of elderly adults at high cardiovascular risk. We followed-up 7216 men (55-80 years) and women (60-80 years) initially free of CVD for up to 7 years in the PREvención con…

One swallow does not make a summer: episodes and persistence in high growth

2021

This paper analyzes firms’ episodes (spells) of high growth (HG) using a sample of Spanish manufacturing firms observed over two decades. The use of duration models allows us to investigate the following: (i) the probability of experiencing HG episodes, (ii) persistence in HG, and (iii) the determinants of the transitions in and out of the HG state and whether their impact varies over the business cycle. We find that about half of the firms experience at least one HG episode, but they seldom experience more than one. Moreover, high-growth status is rarely repeated due to high first-year selection. Yet, in subsequent years beyond the first one, the hazard rate from HG status falls substantia…

New Firm Survival in Developing Countries: Evidence From Kosovo

2019

This paper examines both newborn firm survival and firm turnover in Kosovo using the population of new firms and registry information on active firms from 2008 to 2012. Survival analysis is employed to analyze the impact of firm- and industry-level characteristics on survival. We find that the hazard rate has an inverted U-shape relationship with both firm age and firm size. The risk of failure increases over the first two years and later decreases. In addition, firms with one employee and more than 10 employees enjoy better survival prospects than medium-sized companies. Interestingly, very large firms do not face fewer risks than very small companies. When compared to other developing cou…

Predictive value of heart failure with reduced versus preserved ejection fraction for outcome in pulmonary embolism

2020

Abstract Aims This study aimed to investigate whether the risk of short‐term mortality is different in pulmonary embolism (PE) patients who have heart failure with reduced ejection fraction (HFrEF) as compared with those with heart failure with preserved ejection fraction (HFpEF). Methods and results Predictive value of HFrEF or HFpEF for 7‐day (intrahospital) and 30‐day all‐cause mortality was determined in the cohort of 1055 out of 1201 consecutive acute PE patients from the Serbian multicentre PE registry. Patients were classified into either HFrEF or HFpEF group, according to guideline‐proposed criteria. A 7‐day (intrahospital) and 30‐day all‐cause mortality was 18.5% vs. 7.3% vs. 4.5% …

Genome-wide promoter methylation analysis in neuroblastoma identifies prognostic methylation biomarkers.

2012

Background: Accurate outcome prediction in neuroblastoma, which is necessary to enable the optimal choice of risk-related therapy, remains a challenge. To improve neuroblastoma patient stratification, this study aimed to identify prognostic tumor DNA methylation biomarkers.Results: To identify genes silenced by promoter methylation, we first applied two independent genome-wide methylation screening methodologies to eight neuroblastoma cell lines. Specifically, we used re-expression profiling upon 5-aza-2'-deoxycytidine (DAC) treatment and massively parallel sequencing after capturing with a methyl-CpG-binding domain (MBD-seq). Putative methylation markers were selected from DAC-upregulated …
