A Novel Arthroscopic-Assisted Fibular-Based Dual Reconstruction With Popliteus Repair Technique For Posterolateral Corner Injury: A Cadaveric And Functional Anatomic Study, S. Ali Ghasemi, Ahmad Naja, Benjamin C. Murray, Arthur Bartolozzi, Gene Shaffer, James Raphael

Einstein Health Papers

The structures of the posterolateral corner (PLC) work together as a single unit to provide both static and dynamic functions to the knee. Multiple techniques have been described for PLC reconstruction, however most of these techniques re-establish the static function of the PLC without addressing dynamic components. The popliteus muscle serves an important role in providing dynamic stability to the PLC, but this function is often not restored in reconstruction techniques. We describe a novel technique for PLC reconstruction that includes popliteus repair, and review the functional anatomy and biomechanics of the PLC. We also confirm the dynamic stabilizing role …

Radiotherapy is a pillar of breast cancer treatment; however, it remains unclear how radiotherapy modulates the tumor microenvironment. We investigated this question in a cohort of 20 patients with estrogen-receptor positive (ER+) breast tumors who received neoadjuvant radiotherapy. Tumor biopsies were collected before and 7 days postradiation. Single-cell DNA sequencing (scDNA-seq) and scRNA-seq were conducted on 8 and 11 patients, respectively, at these two time points. The scRNA data showed increased infiltration of naive-like CD4 T cells and an early, activated CD8 T cell population following radiotherapy. Radiotherapy also eliminated existing cytotoxic T cells and resulted in myeloid cell increases. …

Heterozygous Kmt2d Loss Diminishes Enhancers To Render Medulloblastoma Cells Vulnerable To Combinatory Inhibition Of Lsd1 And Oxphos, Shilpa S Dhar, Calena Brown, Ali Rizvi, Lauren Reed, Sivareddy Kotla, Constantin Zod, Janak Abraham, Jun-Ichi Abe, Veena Rajaram, Kaifu Chen, Min Gyu Lee

Faculty, Staff and Student Publications

The histone H3 lysine 4 (H3K4) methyltransferase KMT2D (also called MLL4) is one of the most frequently mutated epigenetic modifiers in many cancers, including medulloblastoma (MB). Notably, heterozygous KMT2D loss frequently occurs in MB and other cancers. However, its oncogenic role remains largely uncharacterized. Here, we show that heterozygous Kmt2d loss in murine cerebellar regions promotes MB genesis driven by heterozygous loss of the MB-suppressor gene Ptch via the upregulation of tumor-promoting programs (e.g., oxidative phosphorylation [OXPHOS]). Downregulation of the transcription-repressive tumor suppressor NCOR2 by heterozygous Kmt2d loss, along with Ptch

Overcoming Nk-Mediated Rejection By Anti-3rd-Party Central Memory Veto Cd8 T Cells Through Downregulation Of Dnam-1 On Alloreactive Nk Cells, Wei-Hsin Liu, Aloukick Kumar Singh, Christa Blagdon, Sandeep Kumar Yadav, Einav Shoshan, Esther Bachar-Lustig, Yair Reisner

Faculty, Staff and Student Publications

Anti-3rd-party central memory veto CD8 T (veto Tcm) cells can overcome T cell-mediated graft rejection under mild conditioning without causing significant graft versus host disease (GVHD). We previously demonstrated that these veto Tcm cells can effectively delete anti-donor T cell clones through a Fas-FasL mechanism, whereas their ability to neutralize alloreactive natural killer (NK) cells and the mechanism of such potential activity remained unknown. Using “nude” mice as recipients of allogeneic T cell-depleted hematopoietic stem cell transplantation (HSCT), we demonstrate effective inhibition of NK-mediated rejection by Tcm cells. Ex vivo studies revealed that Tcm cells express high levels of CD155, …

Biofilms are an important colonization mechanism employed by several microbial species to better establish themselves and monopolize the acquisition of resources across different environs. Some bacteria have evolved specialized metabolites that, when secreted, disrupt the formation and stability of biofilms generated by competing heterospecies, providing the producing organism with an ecological advantage. Soil-derived species are probable candidates for the identification of such compounds, given the intense level of competition that occurs within the terrestrial ecosystem. The MS14 strain of Burkholderia contaminans isolated from soil in Mississippi has previously been shown to produce antimicrobial compounds like occidiofungin and ornibactin. In this …

Revisiting Traumatic Intracerebral Hemorrhage In The Context Of Enrich: Illustrative Cases, Erik Werheim, Brendan Mcshane, Zachary Sokol, Theodore Hannah, Robert Ziechmann, Phillip Villaneuva

Department of Surgery Faculty Papers

BACKGROUND: Traumatic intracerebral hemorrhage (tICH) is a common form of intracranial hemorrhage after traumatic brain injury (TBI). The role of surgical intervention in tICH remains a subject of discussion. Recent trials, such as Early Minimally Invasive Removal of Intracerebral Hemorrhage (ENRICH), have shown the efficacy of minimally invasive clot evacuation for non-tICH for hemorrhages with volumes of 30-80 mL. The generalizability of ENRICH to tICH remains unclear; however, it demonstrates the need for rigorous studies evaluating the efficacy of surgical intervention in tICH versus medical management.

OBSERVATIONS: Here the authors present 2 cases of tICH, both in the dominant temporal …

Image guided radiotherapy (IGRT) using kilovoltage cone-beam CT (CBCT) has become an indispensable tool to ensure the geometric accuracy of radiotherapy treatment delivery. Although significant technical advances have been made in reducing imaging dose, the repeated imaging procedures can still accumulate significant dose to healthy tissues. Despite the widespread use, we still lack clear guidance for optimisation and widely accepted frameworks for evaluating the quality and suitability of CBCT imaging protocols. To address this gap, the 2022 European Society for Radiotherapy and Oncology (ESTRO) Physics Workshop focused on image-quality and imaging-dose optimisation for IGRT using CBCT. This publication represents a …

Steps Toward Clinical Validation Of Exhaled Volatile Organic Compound Biomarkers For Hypoglycemia In Persons With Type 1 Diabetes., Mark Woollam, Paula Angarita-Rivera, Sanskar Thakur, Ali Daneshkhah, Amanda P Siegel, Dana S Hardin, Mangilal Agarwal

Ambulatory and Primary Care Articles

Persons with type 1 diabetes (T1D) must track/control their blood glucose (BG) levels to avoid hypoglycemic events (BG <  70 mg/dL), which in the most severe cases can lead to seizures or even death. Canines may lead the way toward innovative testing solutions, as they can be trained to identify hypoglycemia simply and noninvasively by smelling exhaled volatile organic compounds (VOCs). To identify breath-based biomarkers of hypoglycemia, samples were collected during two consecutive summers at a diabetes camp (Cohort 1 and Cohort 2), and VOCs were analyzed by gas chromatography-mass spectrometry. Conserved VOCs between the two cohorts were identified, but individual VOCs alone had low accuracies for detection. Therefore, supervised multivariate statistical analysis was undertaken to identify a biosignature in the training data set (Cohort 1) that could detect hypoglycemia with higher accuracy (sensitivity = 94.8%/specificity = 95.0%). When this model was blindly tested on Cohort 2, hypoglycemia was classified with sensitivity = 90.0%/specificity = 89.9%. Ultimately, this study makes strides toward clinical validation through verifying biomarkers of hypoglycemia in hundreds of breath samples. These results may be translated to design a sensor array that could be integrated into a portable breathalyzer to increase glycemic control in persons with T1D.

The Cgas/Sting Pathway: Friend Or Foe In Regulating Cardiomyopathy, Weiyue Wang, Yuanxu Gao, Hyun Kyoung Lee, Albert Cheung-Hoi Yu, Markus Kipp, Hannes Kaddatz, Jiangshan Zhan

Duncan NRI Faculty and Staff Publications

Inflammation is a central hallmark of cardiomyopathy, where misdirected immune responses contribute to chronic myocardial dysfunction. Among the emerging molecular mechanisms implicated in this process, the cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING) signaling pathway has garnered increasing attention. Acting as a key cytosolic DNA sensor, the cGAS/STING pathway orchestrates inflammatory responses triggered by microbial infections or endogenous cellular stressors such as autophagy and apoptosis. Despite its pivotal role, the precise molecular mechanisms regulating this pathway and its role in cardiomyopathy-associated inflammation remain poorly understood and subject to ongoing debate. To address this scientific gap, we first reviewed key …

Pharmacy Faculty Articles and Research

Background and Objectives: Neuronal nitric oxide synthase (nNOS) overexpressed in melanoma plays a critical role in disease progression. Our previous studies demonstrated that nNOS inhibitors exhibited potent anti-melanoma activity and regulated PD-L1 expressions in the presence of interferon-gamma (IFN-γ). However, the role of nNOS in the melanoma immune response has not been well defined. Methods: Changes in gene expression profiles after nNOS inhibitor treatment were determined by transcriptomic analysis. A melanoma mouse model was used to determine the effects of nNOS inhibition on peripheral T cells and the in vivo anti-tumor activity of combining nNOS inhibitors with immune …

Implementation Of A Tracheostomy Discharge Education Class For Nicu Nurses, Todd N. Chamoy

Doctor of Nursing Practice Final Manuscripts

Infants who are ventilator-dependent or have anatomic anomalies of their airway frequently require tracheostomy placement prior to discharge from the hospital in order to be cared for safely at home. At this large quaternary children’s hospital in Southern California, preparing these infants for discharge after tracheostomy placement has not been the role of the NICU nurse. There was no system in place on how to train caregivers, and the NICU staff felt unprepared. Evidence supports use of intensive educational programs to improve nurse knowledge and skills of tracheostomy care, allowing NICU nurses to provide improved care and pre-discharge teaching.

Implementing The Fib-4 Tool For Liver Fibrosis Screening In Diabetic Patients In Primary Care, Robert I. Montillano

Doctor of Nursing Practice Final Manuscripts

Abstract

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly non-non-alcoholic fatty liver disease (NAFLD), affects over 1 in 3 adults with type 2 diabetes mellitus (T2DM) and is a leading cause of advanced liver fibrosis. Despite guideline support from the American Diabetes Association (ADA) and American Association for the Study of Liver Diseases (AASLD), screening practices remain inconsistent in primary care. The Fibrosis-4 (FIB-4) index is a validated, low-cost, noninvasive tool for fibrosis risk stratification, yet it remains underutilized despite its availability in many electronic health record (EHR) systems.

Purpose: This Doctor of Nursing Practice (DNP) evidence-based practice (EBP) project …
