Around and Through: Successful Mitral Paravalvular Leakage Closure Using Both Anterograde and Retrograde Approaches

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Paravalvular leak (PVL) is a recognized complication after surgical mitral valve replacement and may cause heart failure, pulmonary hypertension, or hemolysis when moderate or severe. Although redo surgery is the definitive treatment, it carries substantial risk in elderly patients or those with multiple prior cardiac surgeries.

Pre‐Existing and New‐Onset Atrial Fibrillation in Patients Undergoing Transcatheter Aortic Valve Implantation

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Atrial fibrillation (AF) is a frequent comorbidity in patients with severe aortic valve stenosis undergoing transcatheter aortic valve implantation (TAVI). In addition, new‐onset AF can occur after TAVI. However, data on how AF affects outcomes in patients undergoing TAVI remain conflicting.

Two Central Nervous System Tumors in One Catheter Lab: Time to Rethink Radiation Protection

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Very little research has been done on the possible effects that repeated, frequent, and low‐dose ionizing radiation exposure has on the long‐term health of interventional cardiologists. Aims Following the diagnosis in the same year of two central nervous system tumors in two operators working in the same catheter laboratory, we ...

The Asymmetric Self‐Replicative Alkylation of N‐Arylaldimines Using Organolithium Reagents

open access: yesChemistry – A European Journal, EarlyView.
Here, we report a new asymmetric autoinductive reaction; the addition of nBuLi to N‐arylaldimines to form chiral lithium amides. The reaction proceeds with full conversion and complete transfer of chirality, representing the first example of an asymmetric autoinductive reaction with organolithium reagents.

Tetrazine Ligation in Living Systems: Beyond Fast Kinetics to Effective Bioorthogonality

open access: yesChemistry – A European Journal, EarlyView.
Rapid reaction kinetics (k2) alone do not ensure successful tetrazine ligation in living systems. This review introduces ‘effective orthogonality’—focusing on chemical survival, availability, and encounter—as a practical framework. We highlight how bottlenecks shift from cellular sinks to in vivo delivery limits, offering design strategies for reliable

Sudan at War With Itself: Civilian Devastation in the Civil War

open access: yesConflict Resolution Quarterly, EarlyView.
ABSTRACT A civil war is raging in Sudan between the Sudan Armed Forces (SAF) and the Rapid Support Forces (RSF) along with militia groups. Beginning on April 15, 2023, and continuing at least to this writing (October 15, 2025), civilian noncombatants have been subjected to bombings, beatings, torture, shootings, rape, and murder on a large scale. Since

Governance for Pension Plans' Sustainable Transition: The Moderating Role of Corporate Social Identity

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Pension plans may either limit their sustainability approach to commercial purposes or adopt governance practices aligned with sustainability principles, thereby strengthening their Corporate Social Identity (CSI). This paper explores the moderating role of CSI in the relationship between traditional corporate governance mechanisms and pension

Environmental, Social, and Governance (ESG) Performance and Equity Misvaluation: The Moderating Role of Country‐Level Factors

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study explores how corporate environmental, social, and governance (ESG) performance affects equity misvaluation and how country‐level factors—national culture, environmental performance indicators, and world governance indicators (WGIs)—moderate the relationship between corporate ESG performance and misvaluation.
