Field-Directed Motion, Cargo Capture, and Closed-Loop Controlled Navigation of Microellipsoids.

Microrobots have the potential for diverse applications, including targeted drug delivery and minimally invasive surgery. Despite advancements in microrobot design and actuation strategies, achieving precise control over their motion remains challenging due to the dominance of viscous drag, system disturbances, physicochemical heterogeneities, and stochastic Brownian forces. Here, a precise control over the interfacial motion of model microellipsoids is demonstrated using time-varying rotating magnetic fields.

Selective Vapor Condensation for the Synthesis and Assembly of Spherical Colloids with a Precise Rough Patch.

Patchy particles occupy an increasingly important space in soft matter research due to their ability to assemble into intricate phases and states. Being able to fine-tune the interactions among these particles is essential to understanding the principles governing the self-assembly processes. However, current fabrication techniques often yield patches that deviate chemically and physically from the native particles, impeding the identification of the driving forces behind self-assembly.

Dalbavancin Sequential Therapy for Gram-Positive Bloodstream Infection: A Multicenter Observational Study.

Introduction: Long-acting lipoglycopeptides such as dalbavancin may have utility in patients with Gram-positive bloodstream infections (BSI), particularly in those with barriers to discharge or who require prolonged parenteral antibiotic courses. A retrospective cohort study was performed to provide further multicenter real-world evidence on dalbavancin use as a sequential therapy for Gram-positive BSI.

Methods: One hundred fifteen patients received dalbavancin with Gram-positive BSI, defined as any positive blood culture or diagnosed with infective endocarditis, from 13 centers geographically spread across the United States between July 2015 and July 2021.

Sacituzumab Govitecan for Treatment of Refractory Triple-Negative Metastatic Breast Cancer.

Sacituzumab govitecan was initially approved in April 2020 under accelerated approval for the treatment of patients with metastatic triple-negative breast cancer who received at least two prior therapies for metastatic disease. A confirmatory phase III trial evaluating sacituzumab govitecan vs. chemotherapy of the provider's choice was published in April 2021.

Functional Outcomes After Gunshot Wounds to the Foot and Ankle.

The peer-reviewed, clinical data focusing on foot and ankle gunshot wounds are limited. The present study aimed to evaluate functional outcomes in a case series according to the area of injury, articular involvement, and the presence of infection. From January 2003 through February 2011 (8 years), 37 patients treated at Sinai-Grace Hospital (Detroit, MI) for civilian gunshot wounds localized to the foot and/or ankle were reviewed.
