Epilepsy affects approximately 50 million people worldwide, yet more than half of individuals with a presumed genetic cause still lack a molecular diagnosis despite the identification of over 1,000 monogenic epilepsy genes. This diagnostic gap is unlikely to be resolved by improved variant detection alone, suggesting that variants affecting the same biological pathway may combine to cause disease. By studying epilepsy-associated actin regulatory genes, we identified a conserved "actin-mitochondria-glutamate (AMG) pathway". We demonstrate that reduced actin polymerization promotes DRP1-mediated mitochondrial fission, increases reactive oxygen species (ROS) levels, and enhances glutamatergic transmission, leading to seizures. The glial innate immune pathway, a …

BACKGROUND

Sepsis is a leading cause of morbidity and mortality in critically ill children, yet heterogeneous immune responses complicate the development of targeted therapies and the host immune factors driving sepsis pathobiology remain unclear.

METHODS

We integrated deep immune phenotyping, plasma proteomics, single-cell transcriptomics, and phosphoflow cytometry in a prospective cohort of 88 critically ill children to elucidate the mechanisms underlying immune heterogeneity.

RESULTS

Unsupervised clustering of plasma cytokines identified 3 immunologic subgroups, including a high-severity group (“Group C”) characterized by hypercytokinemia driven by IL-6 and IFN-γ. Group C exhibited distinct alterations in immune cell frequency and activation, with a …

High Burden Of Elevated Fib-4 In Metabolically At-Risk Primary Care Patients: Simple Predictors To Guide Hepatic Fibrosis Triage, Ridwan Ademola Lawal, Fatimah Bello, Rashmee Patil, Juliana Yang

Research Symposium

Background: Metabolic dysfunction–associated steatotic liver disease (MASLD), including metabolic dysfunction–associated steatohepatitis (MASH), is a leading cause of chronic liver disease worldwide. Current guidelines recommend fibrosis-based risk stratification using noninvasive tools such as the Fibrosis-4 (FIB-4) index in patients with metabolic risk factors, followed by secondary assessment (e.g., transient elastography or enhanced liver fibrosis(ELF) testing) for those with elevated scores. However, data on the real-world prevalence of elevated FIB-4 in U.S. primary care populations, particularly in safety-net settings, and the downstream implications for fibrosis evaluation remain limited. We aimed to quantify the burden of elevated FIB-4 in a primary care setting …

Purpose: Heterozygous pathogenic variants in AXIN2 (HGNC 904) cause oligodontia-colorectal cancer syndrome (ODCRCS). We identified five individuals with de novo, heterozygous variants (NM_004655.4:c.196G>A p.(Glu66Lys), c.197A>G p.(Glu66Gly), and c.199G>A p.(Gly67Arg)) in AXIN2. Common phenotypes among these individuals included ectodermal dysplasia, global developmental delay, microcephaly, and limb, ophthalmologic, and genitourinary abnormalities.

Methods: Structural modeling was performed to predict the impact of these variants on AXIN2. A prime editing N1 screen of mouse embryos was performed to test whether the p.Glu66Lys variant produces a phenotype. Drosophila models were used to test the effect of this variant on Wnt signaling.

Faculty, Staff and Students Publications

Despite the increased risk of invasive pneumococcal disease among pediatric hematopoietic cell transplant (HCT) recipients, pneumococcal colonization has not been evaluated in this population. We prospectively assessed longitudinal pneumococcal colonization in 22 pediatric HCT recipients from conditioning therapy to 100 days post-HCT. A higher likelihood of pneumococcal colonization was observed in the late post-HCT period (weeks 9-14) compared with the early post-HCT period (weeks 1-8), with odds increasing with each additional week after conditioning.IMPORTANCEThis is the first study to longitudinally evaluate pneumococcal colonization in pediatric hematopoietic cell transplant (HCT) recipients from the onset of conditioning therapy to 100 days post-HCT. …

Emerging Strategies For Cardio-Renal Protection Beyond Raas Blockade: Emphasis On Non-Diabetic Ckd And Resistant Hypertension, Fahad S. Alrashidi

Saudi Medical Journal

Non-diabetic chronic kidney disease (ND-CKD) complicated by resistant hypertension remains a high-risk phenotype even when renin–angiotensin system blockade is optimized. This review synthesizes contemporary evidence for cardio-renal protection beyond traditional renin-angiotensin-aldosterone system inhibition (RAASi), with emphasis on mechanisms, clinical trial data, and pragmatic sequencing. Sodium–glucose cotransporter 2 inhibitors provide hemodynamic and tubular benefits that translate into renal and heart failure risk reduction in many patients with ND-CKD. Non-steroidal mineralocorticoid receptor antagonism (MRA) like finerenone targets inflammatory and fibrotic signaling and may add incremental benefit when potassium is proactively managed. The GLP-1 receptor agonists offer cardiometabolic advantages with emerging kidney signals, …

The Use Of Platelet-Rich Plasma For De Quervain's Tenosynovitis: A Systematic Review With Limited Meta-Analysis, Abdullah W. Abumadian, Mohanad I. Binibrahim, Abdurrahman H. Sultan, Mohammed A. Addas, Hattan Y. Bamagaus, Sultan K. Alhaddad, Motasem O. Bamabad, Bayan A. Ghalimah

Saudi Medical Journal

Introduction: De Quervain's tenosynovitis (DQT) is a painful wrist condition that impairs daily activities. Corticosteroid (CS) injections are commonly used for symptom relief, but their effects may diminish over time. Platelet-rich plasma (PRP) has emerged as a regenerative alternative that promotes tissue healing rather than merely suppressing inflammation. This systematic review and limited meta-analysis compare the efficacy and safety of PRP versus CS injections in DQT. A limited meta-analysis was chosen due to the high heterogeneity between studies (I² = 98.7%). Methodology: A comprehensive literature search identified six studies comparing PRP and CS injections. Pain and functional outcomes …

High-Order Brain Interactions During Ketamine-Induced State Changes: A Functional Marker Of Response In Late-Life Treatment-Resistant Depression?, Krisha Shah, Rubén Herzog, Alan C Swann, Brittany O'Brien, Rahul Balakrishnan, Sanjay J Mathew, Nicholas Murphy

Faculty, Staff and Students Publications

Ketamine is a fast-acting intervention for treatment-resistant depression (TRD), yet only a subset of patients show robust clinical response, and the underlying neural mechanisms remain unclear. High-order interactions (HOI) derived from multivariate information theory provide a framework for examining nonlinear dependencies among brain regions beyond pairwise connectivity. One such metric, the O-information, captures the balance between synergistic and redundant interactions across three or more variables. In this secondary analysis of a randomized, double-blind, midazolam-controlled trial (NCT02556606), we examined EEG-derived HOI in 30 late-life veterans with TRD following a single 40-minute intravenous infusion of ketamine (0.1, 0.25, 0.5 mg/kg; n = …

Multiplexed Plasmon-Enhanced Lateral Flow Assay For Early Diagnosis Of Acute Kidney Injury, Heng Guo, Yuxiong Liu, Ravi Jada, Ying Liu, Carissa Ng, Aquiles Payte, Jiaying Xu, Connor Malone, Jie Zhao, Kedhareswara Sairam Pasupuleti, Arda Aidan Arikan, Sameer Thadani, Srikanth Singamaneni, Ayse Akcan Arikan, Limei Tian

Faculty, Staff and Students Publications

Early diagnosis of acute kidney injury (AKI) remains a major clinical challenge due to the delayed and insensitive nature of conventional markers such as serum creatinine. Urinary protein biomarkers, including neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C (CysC), provide earlier and complementary information on kidney injury, but their clinical translation is limited by the lack of rapid, quantitative, and multiplexed point-of-care (POC) diagnostic tests. Here, we report a multiplexed plasmonic-fluor-based lateral flow assay (p-LFA) that enables sensitive, quantitative, and simultaneous detection of NGAL and CysC. By harnessing ultrabright plasmonic-fluor nanolabels and ratiometric fluorescence analysis, the p-LFA achieves picogram-per-milliliter analytical sensitivity …
