According to the Risk-Need-Responsivity model, criminogenic needs are important in predicting violent behavior. Eight criminogenic needs are considered strong predictors: history of antisocial behavior, antisocial personality traits, criminal attitudes, criminal associates, substance abuse, family problems, poor work performance, and lack of involvement in prosocial leisure/recreation activities. The purpose of the current study was to examine whether seven criminogenic needs predict institutional misconduct in the first year of admission of Dutch patients who were admitted to a forensic hospital.

Structural, architectural, contractile or electrophysiological alterations may occur in the left atrium (LA). The concept of LA cardiopathy is supported by accumulating scientific evidence demonstrating that LA remodeling has become a cornerstone diagnostic and prognostic marker. The structure and the function of LA and left atrial appendage (LAA) which is an integral part of the LA, are key elements for a better understanding of multiple clinical conditions, most notably atrial fibrillation (AF), cardioembolism, heart failure and mitral valve diseases.

Hybrid polyionic complexes (HPICs) are colloidal structures with a charged core rich in metal ions and a neutral hydrophilic corona. Their properties, whether as reservoirs or catalysts, depend on the accessibility and environment of the metal ions. This study demonstrates that modifying the coordination sphere of these ions can tune the properties of HPICs by altering the composition of the complexing block or varying formulation conditions.

Persistent, Private and Mobile genes: a model for gene dynamics in evolving pangenomes.

Mol Biol Evol

January 2025

Center for Interdisciplinary Research in Biology (CIRB), College de France, CNRS, INSERM, Université PSL, Paris, France.

The pangenome of a species is the set of all genes carried by at least one member of the species. In bacteria, pangenomes can be much larger than the set of genes carried by a single organism. Many questions remain unanswered regarding the evolutionary forces shaping the patterns of presence/absence of genes in pangenomes of a given species.

Hybrid Arch Aneurysm Repair With Ascending Aortic Wrap and TEVAR.

J Endovasc Ther

January 2025

Aortic Center, Hôpital Marie-Lannelongue, Groupe Hospitalier Paris Saint Joseph, Université Paris-Saclay, INSERM UMR_S 999, Le Plessis Robinson, France.

Introduction: Management of patients with large aortic arch aneurysms who are considered high risk for frozen elephant trunk technique have been challenging, especially when they have a dilated ascending aorta (AA) that precludes total endovascular branched repair (arch BEVAR). A viable option in our armamentarium is wrapping of the AA (AW), and zone 0 Ishimaru TEVAR.

Methods: Retrospective analysis of our aortic database from 2013 to 2024 to select high-risk patients with aortic arch aneurysm that had an AW and TEVAR.
