Predicting relapse after a first episode of non-affective psychosis: A three-year follow-up study

2011

Preventing relapse during the first years of illness has a critical impact on lifelong outcomes in schizophrenia. A better understanding and improvement in factors which influence relapse should diminish the risk of relapse and consequently improve the outcome of the illness.To identify factors associated with relapse after 3 years of a first episode in a sample of non-affective psychosis patients who are representative of clinical practice in an epidemiological catchment.We analyzed socio-demographic and clinical data from a cohort of patients who were treated in a specialized early intervention service and who were at risk of relapse during a 3-year follow-up. Univariate analyses, logisti…

Framingham score, renal dysfunction, and cardiovascular risk in liver transplant patients

2015

Cardiovascular (CV) events represent major impediments to the long-term survival of liver transplantation (LT) patients. The aim of this study was to assess whether the Framingham risk score (FRS) at transplantation can predict the development of post-LT cardiovascular events (CVEs). Patients transplanted between 2006 and 2008 were included. Baseline features, CV risk factors, and CVEs occurring after LT (ischemic heart disease, stroke, heart failure, de novo arrhythmias, and peripheral arterial disease) were recorded. In total, 250 patients (69.6% men) with a median age of 56 years (range, 18-68 years) were included. At transplantation, 34.4%, 34.4%, and 33.2% of patients, respectively, ha…

Prognostic Value of a Comprehensive Cardiac Magnetic Resonance Assessment Soon After a First ST-Segment Elevation Myocardial Infarction

2009

ObjectivesTo evaluate the prognostic value of a comprehensive cardiac magnetic resonance (CMR) assessment soon after a first ST-segment elevation myocardial infarction (STEMI).BackgroundCMR allows for a simultaneous assessment of wall motion abnormalities (WMA), WMA with low-dose dobutamine (WMA-dobutamine), microvascular obstruction, and transmural necrosis. This approach has been proven to be useful to predict late systolic recovery soon after STEMI. Its prognostic value and the relative prognostic weight of these indexes are not well-defined.MethodsWe studied 214 consecutive patients with a first STEMI treated with thrombolytic therapy or primary angioplasty discharged from hospital. In …

Lung Preservation With Perfadex or Celsior in Clinical Transplantation: A Retrospective Single-Center Analysis of Outcomes.

2015

BACKGROUND Despite improvement of lung preservation by the introduction of low-potassium dextran (LPD) solution, ischemia-reperfusion injury remains a major contributor to early post-lung transplant graft dysfunction and mortality. After favorable experimental data, Celsior solution was used in our clinical lung transplant program. Data were compared with our historic LPD cohort. METHODS Between January 2002 and January 2005, 209 consecutive lung transplantations were performed with LPD. These were compared to 208 transplants between February 2005 and September 2007 with Celsior. Endpoints included posttransplant PaO2/FiO2 ratio at different timepoints after intensive care unit (ICU) admiss…

Total polyphenol intake, polyphenol subtypes and incidence of cardiovascular disease: The SUN cohort study.

2018

Abstract Background and aims Polyphenol-rich diets have been associated with reduced risk of cardiovascular disease (CVD). However, few prospective epidemiological studies have examined the relationship between classes of ingested polyphenols and risk of CVD. Our aim was to evaluate the association between polyphenol intake and risk of major cardiovascular events in a prospective Spanish cohort. Methods and results We included 17,065 university graduates (60.7% women, mean age: 37.2 years, age range: 20–89) followed-up for a mean of 10.1 years. Polyphenol intake was assessed at baseline using a validated semi-quantitative 136-item food frequency questionnaire and matching food consumption d…

Endarterectomy Versus Angioplasty in Patients with Symptomatic Severe Carotid Stenosis (EVA-3S) trial: results up to 4 years from a randomised, multi…

2008

Summary Background Carotid stenting is a potential alternative to carotid endarterectomy but whether this technique is as safe as surgery and whether the long-term protection against stroke is similar to that of surgery are unclear. We previously reported that in patients in the Endarterectomy Versus Angioplasty in Patients with Symptomatic Severe Carotid Stenosis (EVA-3S) trial, the rate of any stroke or death within 30 days after the procedure was higher with stenting than with endarterectomy. We now report the results up to 4 years. Methods In this follow-up study of a multicentre, randomised, open, assessor-blinded, non-inferiority trial, we compared outcome after stenting with outcome …

Impact of routine angiographic follow-up after angioplasty

1998

Abstract Background There is an ongoing controversy as to whether repeat coronary angiography should be routinely performed after successful percutaneous transluminal coronary angioplasty (PTCA). Methods We examined the 10-year outcome in 400 patients who had or had not undergone an angiographic control 6 months after successful PTCA and a subsequent event-free 6-month period. Our comparison was based on data gathered by questionnaire and telephone interview in 315 patients with (group A) and 85 patients without (group B) a routine 6-month angiographic control. Multivariate analysis (Cox model) was performed to identify predictors of adverse events. Results During the 10-year follow-up peri…

Disease-modifying drugs can reduce disability progression in relapsing multiple sclerosis

2020

Abstract An ever-expanding number of disease-modifying drugs for multiple sclerosis have become available in recent years, after demonstrating efficacy in clinical trials. In the real-world setting, however, disease-modifying drugs are prescribed in patient populations that differ from those included in pivotal studies, where extreme age patients are usually excluded or under-represented. In this multicentre, observational, retrospective Italian cohort study, we evaluated treatment exposure in three cohorts of patients with relapsing-remitting multiple sclerosis defined by age at onset: paediatric-onset (≤18 years), adult-onset (18–49 years) and late-onset multiple sclerosis (≥50 years). We…

Primary HBB gene mutation severity and long-term outcomes in a global cohort of β-thalassaemia

2021

In β-thalassaemia, the severity of inherited β-globin gene mutations determines the severity of the clinical phenotype at presentation and subsequent transfusion requirements. However, data on associated long-term outcomes remain limited. We analysed data from 2109 β-thalassaemia patients with available genotypes in a global database. Genotype severity was grouped as β0 /β0 , β0 /β+ , β+ /β+ , β0 /β++ , β+ /β++ , and β++ /β++ . Patients were followed from birth until death or loss to follow-up. The median follow-up time was 34·1 years. Mortality and multiple morbidity outcomes were analyzed through five different stratification models of genotype severity groups. Interestingly, β0 and β+ mu…
