The Landscape of Vascular Endothelial Growth Factor Inhibition in Retinal Diseases.

Invest Ophthalmol Vis Sci

January 2025

John F. Hardesty, MD, Department of Ophthalmology and Visual Sciences, Washington University School of Medicine in St. Louis, St. Louis, Missouri, United States.

Ever since the US Food and Drug Administration (FDA) approved the first vascular endothelial growth factor (VEGF) antagonist 2 decades ago, inhibitors of VEGF have revolutionized the treatment of a variety of ocular disorders involving pathologic neovascularization and retinal exudation. In this perspective, we evaluate the current status of anti-VEGF therapies and the real-world challenges encountered with maintaining therapeutic outcomes. Finally, we describe novel VEGF-based and combinatorial approaches that are in clinical development.

Introduction: In current and anticipated future conflicts, including large-scale combat operations, medical teams are tasked to provide prolonged casualty care (PCC) or extended patient care that occurs when delays in evacuation exceed the team's capabilities. Although the principles of PCC are often taught to military medical providers using simulation, educators rarely dedicate the time to training required to simulate the prolonged nature of these encounters. Therefore, a lack of knowledge exists regarding which aspects of extended care may be lost in an accelerated training scenario.

Rare cancer survivorship research funding at the National Institutes of Health (NIH), 2017 to 2023.

Cancer Causes Control

January 2025

Office of Cancer Survivorship, Division of Cancer Control and Population Sciences, National Cancer Institute, Bethesda, MD, USA.

Purpose: Rare cancers are defined as those for which there are less than 15 cases per 100,000 in the population annually. While much progress in detection and treatment has been made over the past decade for many rare cancers, less progress has been made in understanding survivorship needs. The objective of this study was to characterize the National Institutes of Health (NIH) cancer survivorship grant portfolio focused on rare cancers and to identify gaps specific to this area of science.

Navigating Copyright Law and Fair Use in the Age of Digital Education.

J Physician Assist Educ

January 2025

Diana T. Noller, DHSc, MMS, MSPT, PA-C, is a founding director, Austin College PA Program, Austin College, Denison, Texas. Legal review of this article was provided by Gregg Shalan, MD, JD, LL.M, Medical Director, Neurocritical Unit, Methodist Dallas Medical Center.

Intellectual property laws were not originally designed to address digital classrooms and shared online learning environments, but these concerns are now relevant to many educational institutions. The recent expansion of technology utilization in health professions education presents educators with the challenges to accurately interpret copyright law and implement best practices under the tenets of fair use. Discerning legal and ethical parameters relevant to copyright law will encourage the implementation of best practices in disseminating information and creating appropriate learning activities in the age of digital education.

Juan M. Salgado, MD, Department of Anesthesiology, University of Kansas School of Medicine-Wichita, Wichita, Kansas. He was responsible for concept initiation, presenting the seminar and workshop, data collection and analysis, drafting the manuscript, and approval of the final manuscript.

Introduction: Physician assistants (PAs) should understand the implications and risks involved with airway management. Our study aimed to facilitate PA students' familiarity with airway management with instruction from anesthesiology residents. We assessed the students' knowledge of airway management both before and after a seminar to see if knowledge was retained.

From molecular dynamics (MD) simulations of melt-quenching and thermal aging procedures in pure Ag, Cu, Ag-Cu binary alloys, and Cu-Zr binary alloys, we have identified two distinct amorphous phases for a metastable undercooled liquid: the homogeneous L-phase with low shear rigidity and the heterogenous G-phase with much higher shear rigidity and a heterogeneity length scale Λ. Here, we examine two-phase equilibration studies showing that the G-phase melts to form the L-phase above ~1,000 K, which then transforms to form the crystal (X) phase; however, below the melting point of the G-Phase (~990 K), the X- and G-phases do not transform into each other. We suggest the presence of a G-phase is likely responsible for embrittlement often observed in metallic glasses.

Bone metastases can disseminate to secondary sites and promote breast cancer progression creating additional clinical challenges. The mechanisms contributing to secondary metastasis are barely understood. Here, we evaluate the prediction power of Her2-expressing (Her2E) circulating tumor cells (CTCs) after analyzing over 13,000 CTCs from a cohort of 137 metastatic breast cancer (MBC) patients with initial HR+/Her2- status and employ preclinical models of bone metastasis (BM) to validate the role of Her2E CTCs in multi-organ metastases.

Macrophages play a crucial role in the immune response during allograft rejection in organ transplantation. Therefore, our study aimed to explore the genomic features of macrophages in mouse heart transplants and use single-cell RNA sequencing to investigate Galectin-9 (Gal-9, Lgals9), a lectin that can mediate the activation and differentiation of immune cells through ligand-receptor interactions, and the effects of its regulation in transplantation. We discovered a new subset of macrophages called "Myoz2+ macrophages", which specifically expressed genes related to myocardial contraction.

In the era of big data, increasing availability of data makes combining different data sources to obtain more accurate estimations a popular topic. However, the development of data integration is often hindered by the heterogeneity in data forms across studies. In this paper, we focus on a case in survival analysis where we have primary study data with a continuous time-to-event outcome and complete covariate measurements, while the data from an external study contain an outcome observed at regular intervals, and only a subset of covariates is measured.

Natural killer (NK) cells can control metastasis through cytotoxicity and IFN-γ production independently of T cells in experimental metastasis mouse models. The inverse correlation between NK activity and metastasis incidence supports a critical role for NK cells in human metastatic surveillance. However, autologous NK cell therapy has shown limited benefit in treating patients with metastatic solid tumors.

In recent years, antimicrobial peptides (AMPs) have emerged as a potent weapon against the growing threat of antibiotic resistance. Among AMPs, the ones containing tryptophan (W) and arginine (R) exhibit enhanced antimicrobial properties, benefiting from the unique physicochemical features of the two amino acids. Herein, we designed three hexapeptides, including WR, DWR (D-isomer), and RF, derived from the original sequence, RWWRWW-NH2 (RW).

Topographic Analysis of the Periorbital Region Including Orbicularis Oculi Muscle Based on Ultrasonography Interpretation.

J Cosmet Dermatol

January 2025

Division in Anatomy and Developmental Biology, Department of Oral Biology, Human Identification Research Institute, BK21 FOUR Project, Yonsei University College of Dentistry, Seoul, South Korea.

Objective: Ultrasonographic examination is easy, fast, safe, and used in various fields; however, its application to the facial area has been limited. Complex anatomical structures are mixed within thin, soft tissues in the facial region; therefore, understanding their structural characteristics is crucial. This study aimed to use ultrasonography to obtain information on the layered structure and soft tissue thickness of the eye area around the orbicularis oculi muscle and provide guidance for clinical practice.

Neighborhood opportunity and residential instability: associations with mental health in middle childhood.

J Child Psychol Psychiatry

January 2025

Epidemiology Branch, Division of Population Health Research, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD, USA.

Background: Neighborhood quality may contribute to child mental health, but families with young children often move, and residential instability has also been tied to adverse mental health. This study's primary goal was to disentangle the effects of neighborhood quality from those of residential instability on mental health in middle childhood.

Methods: 1,946 children from 1,652 families in the Upstate KIDS cohort from New York state, US, were followed prospectively from birth to age 10.
