Does being from a higher social class lead a person to engage in more or less prosocial behavior? Psychological research has recently provided support for a negative effect of social class on prosocial behavior. However, research outside the field of psychology has mainly found evidence for positive or u-shaped relations. In the present research, we therefore thoroughly examined the effect of social class on prosocial behavior. Moreover, we analyzed whether this effect was moderated by the kind of observed prosocial behavior, the observed country, and the measure of social class. Across eight studies with large and representative international samples, we predominantly found positive effect…

Social Inequalities in French Secondary Schools : From Figures to Theories

1996

In spite of the unified type of junior secondary school (the "college") implemented in France since 1975, significant social inequalities of school careers can be observed today. A specific longitudinal study sheds some light on the variety of mechanisms which generate these social inequalities. Difference in academic progress is one mechanism, but parents' strategies are also important. Finally, another aspect of social inequality arises from the school attended, some schools being more selective at the streaming points, these "school effects' being related to the social characteristics of the pupils of the catchment area. All these facts and figures have some relevance with regard to diff…

From rural studies to the analysis of localized social spaces

2014

Urban society seems to have penetrated every corner of France, reducing the object of rural sociology and ethnology to nothing. These disciplines are built on a sharp rural/urban split, reserving the canonical vocabulary of sociology, such as the analysis of social class, for urban settings. Rural studies were founded on an ad hoc conceptualization borrowed from anthropology (peasant society, community, village collectivity, village interconnaissance or everyone knowing each other, notables). The radical development of contemporary rural worlds has swept this conception away. But are today’s contemporary rural worlds the exact equivalents of urban worlds? In this paper we defend the idea th…

Coronary chronic total occlusions and mortality in patients with ventricular tachyarrhythmias.

2020

Aims This study sought to assess the prognostic impact of coronary chronic total occlusions (CTO) in patients presenting with ventricular tachyarrhythmias on admission. Methods and results A large retrospective registry was used, including all consecutive patients presenting with ventricular tachyarrhythmias on admission and undergoing coronary angiography from 2002 to 2016. Patients with a CTO were compared with all other patients (non-CTO) for prognostic outcomes. Statistics comprised Kaplan-Meier and Cox regression analyses. Within a total of 1,461 consecutive patients included with ventricular tachyarrhythmias on admission, a CTO was present in 20%. At midterm follow-up of 18 months, th…

Definition of tachycardia for risk stratification of pulmonary embolism

2020

Tachycardia is a reliable predictor of adverse outcomes in normotensive patients with acute pulmonary embolism (PE). However, different prognostic relevant heart rate thresholds have been proposed. The aim of the study was to investigate the prognostic performance of different thresholds used for defining tachycardia in normotensive PE patients.We performed a post-hoc analysis of normotensive patients with confirmed PE consecutively included in a single-centre and a multi-centre registry. An adverse outcome was defined as PE-related death, need for mechanical ventilation, cardiopulmonary resuscitation or administration of catecholamines.Of 1567 patients (median age: 72 [IQR, 59-79] years; f…

Predilation, sizing and post-dilation scoring in patients undergoing everolimus-eluting bioresorbable scaffold implantation for prediction of cardiac…

2017

Aims: The aim of the study was to develop a scoring model to evaluate the quality of bioresorbable vascular scaffold (BVS) implantation and determine the model's usefulness in predicting adverse cardiac events. Methods and results: The implantation technique and clinical outcomes of 1,736 lesions treated with BVS were analysed using the GHOST-EU registry. Predilation, scaffold sizing, and post-dilation (PSP) were scored according to the hazard model derived from the weight of these variables. The primary end-point was a one-year device-oriented composite endpoint (DoCE) composed of cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularisation. Def…

Performance of EU-TIRADS in malignancy risk stratification of thyroid nodules. A meta-analysis

2020

Objective: Several thyroid imaging reporting and data systems (TIRADS) have been proposed to stratify the malignancy risk of thyroid nodule by ultrasound. The TIRADS by the European Thyroid Association, namely EU-TIRADS, was the last one to be published. Design: We conducted a meta-analysis to assess the prevalence of malignancy in each EU-TIRADS class and the performance of EU-TIRADS class 5 vs 2, 3 and 4 in detecting malignant lesions. Methods: Four databases were searched until December 2019. Original articles reporting the performance of EU-TIRADS and adopting histology as reference standard were included. The number of malignant nodules in each class and the number of nodules classifi…

Complex regional pain syndrome - phenotypic characteristics and potential biomarkers

2018

Complex regional pain syndrome (CRPS) is a pain condition that usually affects a single limb, often following an injury. The underlying pathophysiology seems to be complex and probably varies between patients. Clinical diagnosis is based on internationally agreed-upon criteria, which consider the reported symptoms, presence of signs and exclusion of alternative causes. Research into CRPS biomarkers to support patient stratification and improve diagnostic certainty is an important scientific focus, and recent progress in this area provides an opportunity for an up-to-date topical review of measurable disease-predictive, diagnostic and prognostic parameters. Clinical and biochemical attribute…

Accuracy of Transient Elastography in Assessing Fibrosis at Diagnosis in Naïve Patients With Primary Biliary Cholangitis: A Dual Cut-Off Approach

2021

Background & aims Liver fibrosis holds a relevant prognostic meaning in primary biliary cholangitis (PBC). Non-invasive fibrosis evaluation using vibration-controlled transient elastography (VCTE) is routinely performed. However, there is limited evidence on its accuracy at diagnosis in PBC. We aimed to estimate the diagnostic accuracy of VCTE in assessing advanced fibrosis at disease presentation in PBC. Approach & results We collected data from 167 consecutive treatment-naive PBC patients who underwent liver biopsy(LB) at diagnosis at six Italian centers. VCTE examinations were completed within 12 weeks of LB. Biopsies were scored by two blinded expert pathologists, according to Ludwig sy…
