Children affected by armed conflict suffer devastating physical, emotional, and social harm. War uproots families, forcing many to flee as refugees or internally displaced persons, while others remain trapped in dangerous environments. In these crises, children face disproportionate risks-violence, exploitation, disrupted education, and collapsed healthcare systems. Their unique vulnerabilities require urgent, targeted action to protect their health, rights, and development. Beyond immediate care, the humanitarian principle of témoignage-bearing witness-is essential. Rooted in humanitarian ethics, témoignage means speaking out about injustice, amplifying the voices of those affected, and driving systemic change. It challenges traditional notions of neutrality and calls on humanitarian …

Background and objectives: Physical abuse is a common cause of morbidity in infants but is often missed in those with medically minor injuries, increasing the risk for escalating violence. Our objective was to compare the prevalence of abuse-specific injuries among infants with and without prior injuries.

Methods: This is a retrospective, multicenter study of infants (aged < 12 months) undergoing child abuse pediatrics provider (CAP) consultation for suspected physical abuse between 2/2021 and 12/2022 at 10 participating US centers. Encounters were dichotomized into those with and without history of prior injury. The groups were compared for rates of diagnostic screening and prevalence of abuse-specific injuries. The association of prior injuries with identification of abuse-specific injury was assessed using logistic regression controlling for demographics and presence of prior injury.

Results: We identified 2352 eligible encounters (median age: 4.2 months), of which 13% had a history of prior injury. In infants who underwent diagnostic testing, injury identification was significantly higher in those with prior injury (45% vs 22%, P < .05). Adjusting for patient characteristics, the presence of prior injury in infants was associated with higher odds of at least 1 type of abuse-specific injury being identified, compared with those without prior injury (adjusted odds ratio = 2.81, 95% CI = 2.10-3.76).

Conclusion: Infants with prior injury …

Poststroke Impulsivity: A Narrative Review, Melissa B Jones, Dakota E Broadway, Malena Gimenez-Zapiola, Ricardo E Jorge

Faculty, Staff and Students Publications

In this narrative review, the authors examine the multidimensional nature and presentations of impulsivity after stroke. Impulsivity manifests as immediate or premature responses, impaired delayed gratification, perseverance despite punishment, and other displays of impaired emotional and behavioral regulation. The literature on the assessments, outcomes, and treatment of patients with these various manifestations after a cerebrovascular injury is reviewed. Findings from case reports indicate that poststroke impulsivity may manifest across neurobehavioral syndromes that are not well defined in the psychiatric nomenclature, such as alien hand syndrome and atypical impulse control disorders. Overall, impulse control disorders appear to be rare poststroke. Therapeutic …

This process often requires intensive labor, creating barriers for deployment in low- and middle-income countries (LMICs). We aimed to establish the feasibility of implementing knowledge-based auto-planning to facilitate clinical efficiency and increase patient throughput in an LMIC.

Materials and methods: We evaluated 60 randomly selected VMAT manual plans (VMPs), including 10 for each of the following sites: head and neck, oesophagus, breast, prostate, cervical, and rectal cancers. Using the same …

Internal Carotid Artery Sympathetic Plexus Neurofibroma – A Case Report, Pedram Daniel Maleknia, Victor Lara, Ailiang Zeng, Michael Benjamin Larkin, Vijay Nitturi, Diego Rojas, Sean Lau, Elizabeth Ledbetter, Akash J Patel

Faculty, Staff and Students Publications

Background: Neurofibromas are benign peripheral nerve sheath tumors most associated with neurofibromatosis type 1 (NF1 ). NF1 is an autosomal dominant disorder resulting from mutations in the NF1 gene located on chromosome 17. While neurofibromas frequently occur in cutaneous or plexiform forms, neurofibromas arising from the sympathetic plexus of the internal carotid artery (ICA) are rare. Only one case of an intracranial sympathetic plexus neurofibroma has been reported in the literature to date. Since most nerve sheath tumors arising from this region are schwannomas, and given the intimate association with the Internal carotid artery (ICA) and surrounding neurovascular structures of …

Modeling Functional Connectivity With Learning And Memory In A Mouse Model Of Alzheimer’S Disease, Lindsay Fadel, Elizabeth Hipskind, Steen E Pedersen, Jonathan Romero, Caitlyn Ortiz, Eric Shin, Md Abul Hassan Samee, Robia G Pautler

Faculty, Staff and Students Publications

Introduction: Functional connectivity (FC) is a metric of how different brain regions interact with each other. Although there have been some studies correlating learning and memory with FC, there have not yet been, to date, studies that use machine learning (ML) to explain how FC changes can be used to explain behavior not only in healthy mice, but also in mouse models of Alzheimer's Disease (AD). Here, we investigated changes in FC and their relationship to learning and memory in a mouse model of AD across disease progression.

Methods: We assessed the APP/PS1 mouse model of AD and wild-type controls …

Intraocular Lens Power Calculation In Challenging Cases, Jack X Ma, Li Wang, Douglas D Koch

Faculty, Staff and Students Publications

In this article, we reviewed recently published papers of intraocular lens (IOL) power calculation in special eyes. In short eyes, accurate estimation of effective lens position is critical, and the ZEISS artificial intelligence IOL calculator produces the best outcomes. In long eyes, accuracy has been improved with axial length (AL) adjusted formulas such as the Wang-Koch AL adjustment and newer IOL formulas. In keratoconic eyes, hyperopic refractive outcomes increase with steeper keratometric values, and accuracy is poor in eyes with keratometric values ≥50.0 D. Two keratoconus-specific formulas (Barrett True K for keratoconus and Kane keratoconus) have been introduced. In eyes …

Learning-Associated Astrocyte Ensembles Regulate Memory Recall, Michael R Williamson, Wookbong Kwon, Junsung Woo, Yeunjung Ko, Ehson Maleki, Kwanha Yu, Sanjana Murali, Debosmita Sardar, Benjamin Deneen

Faculty, Staff and Students Publications

The physical manifestations of memory formation and recall are fundamental questions that remain unresolved1. At the cellular level, ensembles of neurons called engrams are activated by learning events and control memory recall1-5. Astrocytes are in close proximity to neurons and engage in a range of activities that support neurotransmission and circuit plasticity6-10. Moreover, astrocytes exhibit experience-dependent plasticity11-13; however whether specific ensembles of astrocytes participate in memory recall remains obscure. Here we show that learning events induce c-Fos expression in a subset of hippocampal astrocytes, which subsequently …

Placentas From Sars-Cov-2 Infection During Pregnancy Exhibit Foci Of Oxidative Stress And Dna Damage, Guilherme M Nobrega, Eliza R Mccoll, Arthur Antolini-Tavares, Renato T Souza, José Guilherme Cecatti, Maria Laura Costa, Indira U Mysorekar

Faculty, Staff and Students Publications

Problem: COVID-19 during pregnancy is linked to increased maternal morbidity and a higher incidence of preterm births (PTBs), yet the underlying mechanisms remain unclear. Cellular senescence, characterized by the irreversible cessation of cell division, is a critical process in placental function, and its dysregulation has been implicated in pregnancy complications like PTB. Senescence can be induced by various stressors, including oxidative stress, DNA damage, and viral infections.

Method of study: In this study, we determined whether COVID-19 had an impact on placental senescence. We examined placentas from women infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (n = 10 …

High Tumor Cd161 Expression Predicts A Survival Advantage And Marks A Th1-Skewed Microenvironment, Briana Amicarella Burns, Manasvi Chandra, Vanaja Konduri, William K Decker

Faculty, Staff and Students Publications

CD8+CD161+ T-cells exhibit augmented memory and cytolytic properties, mediating enhanced immunity in murine tumor models and improved survival in human non-small cell lung cancer. This T-cell subset might serve as a biomarker of positive response to therapy or even be isolated to augment current immunotherapeutic approaches yet limited knowledge of CD161 expression in human cancers restricts practical application. Here we bioinformatically tested the hypothesis that CD161 expression may be associated with positive outcomes in human cancers and investigated mechanisms underlying any observed advantages. Using TCGA-PANCAN dataset, we analyzed expression of CD161 in over 10,000 human tumors, correlating expression levels with …

The Reprogramming Factor Klf4 In Normal And Malignant Blood Cells, H Daniel Lacorazza

Faculty, Staff and Students Publications

The Krüppel-like factor 4 (KLF4) is an evolutionarily conserved zinc finger transcription factor that regulates cellular processes in stem cells, epithelial cells, and immune blood cells by controlling gene expression through genetic, epigenetic, and chromatin remodeling. The landmark 2006 publication identified KLF4 as one of the factors involved in reprogramming differentiated cells into pluripotent stem cells, sparking increased interest in KLF4 research a decade after its discovery, particularly in the fields of stem cell research, epithelial cell biology, endothelial cell function, and tumorigenesis. Over the years, KLF4 has emerged as a key transcription factor in modulating innate and adaptive immunity, …

Faculty, Staff and Students Publications

Patients with immune dysregulation may present with varying combinations of autoimmunity, autoinflammation, immunodeficiency, atopy, lymphoproliferation, and/or malignancy, often with multisystem involvement. Recognizing specific patterns of immune dysregulation, coordinating and interpreting complex diagnostic testing, and choosing initial (often empiric) treatment can be challenging. Centers are increasingly assembling multidisciplinary teams (MDTs) to standardize evaluation and optimize treatment of patients with complex immune dysregulation (immune dysregulation MDTs [immMDTs]). However, published information on the composition and function of immMDTs is sparse, and there is little guidance for those seeking to establish or optimize an immMDT. To inform this review, we assembled a panel of …

Two-Dimensional Speckle Tracking Of The Ascending Aorta: A Novel Approach To Evaluate Arterial Stiffness In Pediatric Patients With Repaired Conotruncal Anomalies Using Echocardiography, Anmol Goyal, Anitha Parthiban, David A White, Daniel Forsha, Doaa Aly

Faculty, Staff and Students Publications

Background: Children with repaired conotruncal abnormalities (CTA) are at risk of progressive aortic dilation and deteriorating aortic elasticity even after surgical correction. Strain imaging, using a 2-dimensional speckle tracking echocardiography (2D-STE), has been used for arterial stiffness assessment, but pediatric data are still lacking. We investigated the feasibility, reproducibility, and clinical value of 2D-STE derived ascending aorta (AAo) stiffness in children with repaired CTA.

Methods: 22 pediatric patients with repaired CTA were included along with 25 age- and sex- matched healthy controls (mean age 10.2 ± 4.5 years). Conventional 2D echocardiographic and 2D-STE assessment of AAo mechanics was performed. M-mode …

A New Interpolated Pseudodifferential Preconditioner For The Helmholtz Equation In Heterogeneous Media, Sebastian Acosta, Tahsin Khajah, Benjamin Palacios

Faculty, Staff and Students Publications

This paper introduces a new pseudodifferential preconditioner for the Helmholtz equation in variable media with absorption. The pseudodifferential operator is associated with the multiplicative inverse to the symbol of the Helmholtz operator. This approach is well suited for the intermediate and high-frequency regimes. The main novel idea for the fast evaluation of the preconditioner is to interpolate its symbol, not as a function of the (high-dimensional) phase-space variables, but as a function of the wave speed itself. Since the wave speed is a real-valued function, this approach allows us to interpolate in a univariate setting even when the original problem …
