Systemic Vascular Dysregulation And Retinal Microvascular Alterations In Glaucoma, Amin Ibrahim, Tori Sayers, Alexa Nichols, Igor Zwir, Andrew Tsin, Lorena Flores-Hernandez, Gladys E. Maestre, Jesus D. Melgarejo

Research Colloquium

Background: Glaucoma is a multifactorial, progressive optic neuropathy, for which both mechanical and vascular mechanisms of pathogenesis have been proposed. Optical coherence tomography angiography (OCTA) enables noninvasive visualization of the choroidal and retinal vasculature and may be used to quantify vascular changes associated with glaucoma. Systemic risk factors, including variations in blood pressure (BP), whether low or elevated, have been associated with the vascular pathogenesis of glaucoma. This systematic review aims to synthesize the current evidence on the relationship between systemic vascular dysregulation and OCTA-derived retinal vascular markers in glaucomatous eyes.

Methods: Following PRISMA guidelines, we conducted a systematic search …

Treatment Evolution In Paroxysmal Nocturnal Hemoglobinuria: A Case Series Of Sequential Treatment Versus Early Iptacopan Use, Alyssa L. Sepulveda, Ronald Shaju, Yolanda Gutierrez, Francisco Arias Reyes, Daniela Hernandez

Research Colloquium

Introduction: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired hematopoietic stem cell disorder characterized by complement-mediated intravascular hemolysis, bone marrow failure, and a heightened risk of thrombosis. Prior to targeted therapies, management of PNH was largely supportive, focusing on transfusions, anticoagulation, and bone marrow transplantation. Thromboembolic events were the leading cause of mortality, accounting for approximately 40-67% of deaths prior to the introduction of complement inhibitors such as eculizumab, a monoclonal antibody targeting terminal complement protein C5. In December 2023, iptacopan, an oral factor B inhibitor that targets the alternative complement pathway, was approved for PNH, offering improved patient compliance …

Einstein Health Papers

BACKGROUND: Tricuspid regurgitation (TR) is a common occurrence in patients with heart failure (HF), and its role in disease progression has gained attention in recent years. Although TR can worsen clinical outcomes in HF patients, the impact of gender, racial, and socioeconomic factors remains largely unexplored. With growing evidence supporting the role of percutaneous interventions for the treatment of significant TR, understanding these disparities is more crucial than ever.

METHODS: Data were extracted from the National Inpatient and National Readmission 2016-2020 Databases. We used ICD-10 code I50 to identify the patients primarily admitted for HF and subdivided the cohort into …


Bard1: A Friend Or Foe In Pancreatic Ductal Adenocarcinoma?, Lily Zekavat, Aditi Jain Sep 2025

Bard1: A Friend Or Foe In Pancreatic Ductal Adenocarcinoma?, Lily Zekavat, Aditi Jain

Department of Surgery Faculty Papers

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive solid malignancy with poor overall prognosis and limited response to standard treatments. Growing interest in the modulation of DNA repair mechanisms, including the homologous recombination (HR) repair pathway, has opened new avenues for therapeutic development. BARD1 (BRCA1-Associated RING Domain 1) plays a complex role in tumor biology, functioning either as a tumor suppressor or as an oncogenic driver, depending on isoform expression, cellular context, and regulatory environment. In this review, we examine the dual roles of BARD1, focusing on its regulation and paradoxical activities in PDAC. We summarize evidence that BARD1 and BARD1 …

Early Definitive Fusion Versus Magnetic Growing Rods In "Tweeners": What Do Parents Prefer?, Sylvia Culpepper, Ravi Rajendra, Brett Lullo, Anthony A. Catanzano, Tyler C. Mcdonald, R Carter Clement

School of Medicine Faculty Publications

INTRODUCTION: In treating early-onset scoliosis (EOS), pediatric orthopaedic surgeons and families must often choose between growth-friendly interventions such as magnetically controlled growing rods (MCGR) and early definitive posterior spinal fusion (PSF). While each strategy has associated pros and cons, little is understood about the specific preferences of patients' families. Addressing potential nuances in these preferences is crucial for meaningful shared decision-making (SDM). To better understand the factors influencing family decisions, we conducted a choice-based conjoint (CBC) analysis to explore parents' preferences for PSF and MCGR as treatment options. METHODS: A survey was developed using Sawtooth Software (Lighthouse Studio version 9.2.0) …

The Predilection Of Specific Diseases To Affect Different Sections Of The Esophagus, Monjur Ahmed

Division of Gastroenterology and Hepatology Faculty Papers

Certain esophageal diseases have a predilection for affecting different parts of the esophagus. This predilection is noted in our clinical practice as we investigate various esophageal diseases using multiple imaging and motility studies, as well as endoscopic procedures with biopsies. Clinical presentations vary with the stage and location of the disease. Clinicians can suspect certain diseases when a particular part of the esophagus is involved and then can perform appropriate investigations. Esophageal diseases with section involvement, with their symptomatology, diagnostic tests, and management, have been discussed in this narrative review. This review aims to revisit those diseases with a current …

Isolated Transaminitis As A Sentinel Sign Of Duchenne Muscular Dystrophy In An Infant: A Case Report, Ayesha Khalid, Tuba Chaudhry, Ayesha Liaqat, Lauren Tufts

School of Medicine Faculty Publications

Duchenne muscular dystrophy (DMD) is an X-linked recessive muscular dystrophy (MD) that typically presents after ambulation due to progressive proximal muscle weakness. The average age of diagnosis is 4.83 years. However, there are some subtle signs that can help in early diagnosis and delay the progression of the disease. We present a non-classical DMD case in a six-month-old infant with failure to thrive, persistent emesis, transaminitis, and truncal weakness, leading to an early diagnosis of DMD. Initial workup for failure to thrive was unremarkable, other than persistently elevated liver enzymes aspartate aminotransferase (AST) and alanine transaminase (ALT) with normal alkaline …

Targeting Kinin B1r Attenuates Hypertension Through At1r-Dependent Mechanisms, Drew Theobald, Riley N. Bessetti, Yumei Feng Earley, Eric Lazartigues, Karen Litwa, Srinivas Sriramula

School of Medicine Faculty Publications

BACKGROUND: Neurogenic hypertension is chronically high blood pressure that is initiated and maintained through excessive sympathetic nervous system activity and has been associated with increased B1R (kinin B1 receptor) activation. We previously reported a central role for B1R in mediating inflammatory pathways in the development of deoxycorticosterone acetate salt hypertension. Additionally, we identified a causal relationship between B1R expression after Ang II (angiotensin II) stimulation, and that B1R can mediate the bidirectional interaction between neuroinflammation and oxidative stress. However, whether there are any interactions between AT1R (Ang II-type I receptor) and B1R, and if B1R can mediate the effects of …

Altered cell surface glycosylation is a hallmark of cancer; among aberrant glycan structures, hypersialylated proteins contribute to disease progression. The enzyme ST6 β-galactoside α2,6-sialyltransferase 1 (ST6GAL1) mediates α2,6-linked sialylation of N-glycosylated proteins and is upregulated in many cancers, including prostate cancer (PrCa). We propose that ST6GAL1 may be released by cancer cells in small extracellular vesicles (sEVs) in the PrCa tumor microenvironment to potentially modulate cell surface sialylation in recipient cells. We isolated sEVs from PrCa cells by density gradient separation and characterized them by nanoparticle tracking analysis using ZetaView and immunoblotting analysis. We identified ST6GAL1 in both its membrane-bound …

Farber Institute for Neuroscience Faculty Papers

Temporal lobe epilepsy (TLE) patients experience shifts between non-seizing and seizing brain states, but the structural networks underlying these transitions remain undefined and poorly characterized. We detected dynamic brain states in resting-state fMRI and constructed linked structural networks utilizing multi-shell diffusion-weighted MR data. Leveraging network control theory, we interrogated the structural data for all possible brain state transitions, identifying those requiring abnormal levels of transition energy (low or high) in TLE compared to matched healthy participants (n's = 25). Results revealed three transitions requiring significantly higher energy in TLE; no abnormally low-energy transitions were observed. In HPs, transitions relied on …
