Five-year follow-up after catheter ablation of persistent atrial fibrillation using the stepwise approach and prognostic factors for success.
2015
Background— In the meantime, catheter ablation is widely used for the treatment of persistent atrial fibrillation (AF). There is a paucity of data about long-term outcomes. This study evaluates (1) 5-year single and multiple procedure success and (2) prognostic factors for arrhythmia recurrences after catheter ablation of persistent AF using the stepwise approach aiming at AF termination. Methods and Results— A total of 549 patients with persistent AF underwent de novo catheter ablation using the stepwise approach (2007–2009). A total of 493 patients were included (Holter ECGs ≥every 6 months). Mean follow-up was 59±16 months with 2.1±1.1 procedures per patient. Single and multiple procedu…
Population-based validation of a German version of the Brief Resilience Scale.
2017
Smith and colleagues developed the Brief Resilience Scale (BRS) to assess the individual ability to recover from stress despite significant adversity. This study aimed to validate the German version of the BRS. We used data from a population-based (sample 1: n = 1.481) and a representative (sample 2: n = 1.128) sample of participants from the German general population (age ≥ 18) to assess reliability and validity. Confirmatory factor analyses (CFA) were conducted to compare one- and two-factorial models from previous studies with a method-factor model which especially accounts for the wording of the items. Reliability was analyzed. Convergent validity was measured by correlating BRS scores …
Risk of Colorectal High-Grade Dysplasia and Cancer in a Prospective Observational Cohort of Patients with Inflammatory Bowel Disease.
2013
International audience; BACKGROUND AND AIMS:: There is an unclear risk of colonic high-grade dysplasia (HGD) and colorectal cancer (CRC) among patients with inflammatory bowel disease (IBD) treated with immunosuppressants. We analyzed data on CRC development among patients with IBD enrolled in the observational cohort Cancers et Surrisque Associé aux Maladies Inflammatoires Intestinales En France (CESAME). METHODS:: We followed and collected data from 19,486 patients with IBD (60.3% with Crohn's disease, 30.1% receiving thiopurine therapy) enrolled in CESAME from May 2004 and June 2005, and followed until December 2007. When the study began, 2841 patients (14.6%) were characterized as havin…
HDL subfractions distribution in renal transplant recipients: Lack of evidence of a reduction of HDL2 particles
1996
Since the high rate of cardiovascular disease in renal transplant recipients, alterations of lipoprotein profile in such patients were extensively evaluated, but the HDL subclass profile was not completely clarified. Renal transplant recipients usually show normal to high plasma levels of HDL cholesterol, even if some investigations suggested a persistence of low HDL2 levels: this was not useful in terms of cardiovascular protection. We designed this study in order to evaluate HDL subfractions distribution in renal transplant recipients. We studied 55 renal transplant recipients, treated with prednisone, azathioprine and/or cyclosporine, and 34 healthy normolipidemics as controls. In all su…
GHPSS multicenter Italian survey: smoking prevalence, knowledge and attitudes, and tobacco cessation training among third-year medical students
2013
Aims and background Healthcare professionals have an important role to play both as advisers – influencing smoking cessation – and as role models. The aims of this study were to examine smoking prevalence, knowledge and attitudes among Italian university students attending medical schools using the Global Health Professions Student Survey (GHPSS) approach. Methods and study design A multicenter cross-sectional study was conducted among University students of 9 Italian medical schools (age ranging between 19 and 29 years). The GHPSS questionnaire was self-administered. A logistic regression model was used to identify possible factors associated with tobacco smoking status. Data were analyzed…
Correlates of victim-blaming attitudes regarding partner violence against women among the Spanish general population.
2014
This article analyzes correlates of victim-blaming attitudes regarding partner violence against women (PVAW) among the Spanish general population ( N = 1,006). Results showed that victim-blaming attitudes were more common among respondents who were older, less educated, and who placed themselves at the bottom of the social scale. Furthermore, the odds of expressing victim-blaming attitudes were higher among respondents who thought that PVAW was common in society, considered it more acceptable, and knew women victims of partner violence in their circle of friends and family. Implications for public education are discussed.
Increased plasma xanthine oxidase activity is related to nuclear factor kappa beta activation and inflammatory markers in familial combined hyperlipi…
2010
Abstract Background and aims Xanthine oxidase (XO) has been described as one of the major enzymes producing free radicals in blood. Oxidative stress and inflammatory processes have been implicated in the pathogenesis of endothelial dysfunction and the progression of atherosclerosis but until now, there is little data about the influence of vascular prooxidant systems and inflammation in familial combined hyperlipidemia (FCH). Our goal was to evaluate whether XO activity was altered in FCH and if it was related to the inflammatory process represented by NFkB, IL-6 and hsCRP, and assessing the correlation between XO activity and insulin resistance (IR). Method and results 40 Non-related subje…
Childhood Environment and Adult Height among Polish University Students
2010
The objective of the study is to assess whether the choice of a childcare type (i.e., a mother giving up a professional career to take care of her child, employing a childminder, day care centre and kindergarten) depends on a child's family socio-economic status and to investigate whether the childcare type affects an adult's height. The material for the study was gathered in the cross-section research carried out among 783 female students and 535 male students of universities in Krakow and Opole (southern Poland). The height was measured with standard anthropometric instruments. To assess a socio-economic status (SES), the following factors were analysed: a place of living before entering …
Prevalence, Phenotype, and Psychosocial Well-Being in Euthyroid/Hypothyroid Thyroid-Associated Orbitopathy.
2015
At the onset of thyroid-associated orbitopathy (TAO), most patients are hyperthyroid, while scarce data are available on euthyroid/hypothyroid TAO. The aim of this study was to assess the prevalence, phenotype, and psychosocial burden of patients with initially euthyroid/hypothyroid TAO.The medical records of 461 consecutive and unselected patients with TAO followed at a specialized joint thyroid-eye clinic were analyzed within this retrospective cross-sectional study. Main outcome measures were the prevalence of initially eu- or hypothyroid TAO as well as ophthalmic signs and symptoms, disease-specific quality of life (QoL), work impairment, and rate of psychotherapy in initially eu-/hypot…
Clinical success of intrauterine insemination cycles is affected by the sperm preparation time.
2013
Objective To determine the impact of the time interval from the end of sperm preparation (TSP) to intrauterine insemination (IUI) on the outcome. Design Prospective multicentre cohort study. Setting Seven French centers (assisted reproduction group in northeastern France, four academic centers, and three clinics). Patient(s) Eight hundred sixty-two IUI cycles (709 patients) managed by gonadotropins were studied. Intervention(s) Cycles were stimulated by either FSH or hMG, and hCG was administrated when the leading follicle diameter measured >15 mm. IUIs were performed ∼36 hours after ovulation triggering. Main Outcome Measure(s) Generalized linear mixed models for binary outcomes were used …
