The Impact of Electric Fields on Processes at Electrode Interfaces.
Chem Rev
January 2025
Department of Chemistry, Emory University, Atlanta, Georgia 30322, United States.
The application of external electric fields to influence chemical reactions at electrode interfaces has attracted considerable interest in recent years. However, the design of electric fields to achieve highly efficient and selective catalytic systems, akin to the optimized fields found at enzyme active sites, remains a significant challenge. Consequently, there has been substantial effort in probing and understanding the interfacial electric fields at electrode/electrolyte interfaces and their effect on adsorbates.

Ann Emerg Med
January 2025
Department of Emergency Medicine, Yale School of Medicine, New Haven, CT; Center for Outcomes Research and Evaluation, Yale School of Medicine, New Haven, CT.
Study Objective: Non-physician practitioners, including nurse practitioners and physician assistants, increasingly practice in emergency departments, especially in rural areas, where they help mitigate physician shortages. However, little is known about non-physician practitioner durability and demographic trends in emergency departments. Our objective was to examine attrition rates and ages among non-physician practitioners in emergency medicine.

JACC Clin Electrophysiol
January 2025
Vanderbilt Heart and Vascular Institute, Nashville, Tennessee, USA. Electronic address:
Background: Programmed electrical stimulation (PES) is an essential part of ventricular tachycardia (VT) ablation procedures, but VT is not always inducible, usually for reasons that are not clear.
Objectives: This study sought to review pacing site-specific failure of PES to induce scar-related VT and to provide a potential mechanistic explanation of the phenomena using a computer simulation.
Methods: Six patients in whom aggressive PES from traditional RV pacing sites failed to induce VT, but VT was easily inducible from a nontraditional site, were reviewed.
Adolescent Coronal Shear Fractures of the Distal Humerus: Surgical Approach and Outcomes.
J Hand Surg Am
January 2025
Department of Orthopaedic Surgery, Washington University School of Medicine, Saint Louis, MO. Electronic address:
Purpose: Isolated coronal shear fractures of the distal humerus in adolescents are rare injuries with unique surgical challenges. Respect for the posterior blood supply, open physes, and need for direct visualization to achieve anatomic reduction are critical considerations in surgical fixation. This study presents a case series and a surgical approach used in treating these patients.

J Hand Surg Am
January 2025
Division of Plastic Surgery, Department of Surgery, University of Pennsylvania, Philadelphia; Division of Plastic, Reconstructive and Oral Surgery, Children's Hospital of Philadelphia, Philadelphia, PA. Electronic address:
Purpose: Acute hand infections (AHIs) remain a challenge for hand surgeons and represent a condition for which clinical outcomes are considerably affected by social barriers. We previously described the looped Penrose drainage technique, where a drain is sutured to itself in a loop and the outflow tract of egress is maintained, thus obviating the need for large incisions, wound closure, or repeat packing, thereby reducing the follow-up burden. In the face of escalating numbers of socioeconomically vulnerable patients, especially in urban settings, we aimed to characterize the clinical features and outcomes of this technique in an urban population of patients with AHI.
