Ethical Issues Involved In Solid Organ Xenotransplantation., Daniel J Hurst, Chris Bobier, Luz A Padilla

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Xenotransplantation (specifically, genetically modified pig-to-human transplant of organs, tissues, or cells) clinical trials are set to begin in the United States after decades of pre-clinical studies and recent decedent and compassionate use investigations. This article provides a primer on the key ethical issues attendant with this emerging therapy. We explore four central areas of concern: (i) the use of animals to meet human transplant needs, as well as their welfare since they are housed in non-natural conditions, (ii) the risk of infectious disease transfer from the porcine graft to the human recipient, known as xenozoonosis, (iii) patient selection criteria for …

Clinical Pharmacokinetics, Pharmacodynamics, And Drug Interactions Of Remimazolam, Derek E. Murrell, Sam Harirforoosh

Pharmacy Faculty Articles and Research

Remimazolam, an ultrashort-acting benzodiazepine, has emerged as a promising sedative agent for procedural sedation and general anesthesia. It combines the favorable properties of traditional benzodiazepines with a rapid onset and offset of action, largely due to its unique metabolism via hepatic carboxylesterases rather than cytochrome P450 enzymes. This metabolism allows for predictable pharmacokinetics, reducing the risk of prolonged sedation and drug accumulation, particularly in patients with hepatic or renal impairment. Clinically, remimazolam demonstrates non-inferiority to midazolam and propofol, with advantages including a lower incidence of hypotension and respiratory depression. Multiple randomized controlled trials have shown its efficacy in various procedural …

Triple-negative breast cancer (TNBC) is an aggressive, heterogeneous subtype of breast cancer. miRNAs play an essential role in TNBC pathogenesis and prognosis. Obesity is linked with an increased risk for several cancers, including breast cancer. Obesity is also related to the dysregulation of miRNA expression in adipose tissues. However, there is limited knowledge about race- and obesity-specific differential miRNA expression in TNBC. We performed miRNA sequencing of 48 samples (24 tumor and 24 adjacent non-tumor tissues) and RNA sequencing of 24 tumors samples from Black (AA) and White (EA) TNBC patients with or without obesity. We identified 55 miRNAs exclusively …

The spinal cord is a highly dynamic network, playing significant roles in the vital functions of the brain. Disorders of the spinal cord, such as spinal cord injury and amyotrophic lateral sclerosis (ALS), are associated with neurodegeneration, often resulting in morbidity and mortality. The blood-brain barrier (BBB) poses a major challenge to imaging and therapeutic agents because less than 2% of small-molecule drugs and almost no large-molecule drugs can cross the BBB. Furthermore, spatial spectroscopy studies have shown highly heterogeneous BBB crossing with significant accumulation at the unintended brain regions. Thus, targeting systems that can cross the BBB at the …

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) …

Mahesh, Harsheen K. Manaise, Jade Bowers, Angel Aguayo Merly, Emmanuel Gabriel

School of Medicine Faculty Publications

This editorial comment is on the article by Xu et al. It offers an in-depth analysis of liver function assessment tools and their prognostic roles in non-malignant liver diseases, with a focus on the albumin-bilirubin (ALBI) score. ALBI’s components, grading system, and clinical relevance across various liver conditions are reviewed and compared with traditional models such as the Child-Pugh and model for end-stage liver disease scores. We included recent studies evaluating ALBI’s role in estimating liver function, suggesting it may help differentiate patients who appear similar under other staging systems, and assist in guiding clinical decisions. Although ALBI is primarily …

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 …

School of Medicine Faculty Publications

BACKGROUND: Opioids are frequently used intraoperatively and during postanesthesia care unit care in total knee arthroplasty (TKA) cases and are commonly prescribed after surgery despite known adverse effects. This study examined whether in-hospital opioid exposure is related to postoperative opioid prescribing in opioid-naïve TKA patients. METHODS: This retrospective study included opioid-naïve patients (no opioid prescriptions filled during the three months before TKA) who had unilateral primary TKA between May 1, 2020, and November 30, 2023, performed by an orthopaedic surgeon. All patients were treated using the same multimodal pain protocol. Opioid prescriptions filled by patients during the three months following …

Distinct Transcriptional Regulation Of The Wnt And Tgfβ Signaling Families Associated With Wound Healing And Fibrotic Outcomes To Lens Injury, Catherine Lalman, Kylie R. Stabler, Joshua Disatham, Lisa A. Brennan, Marc Kantorow, Janice L. Walker

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Posterior capsule opacification (PCO) is a fibrotic complication of cataract surgery caused by aberrant repair of residual lens cells. It remains unclear how the lens injury response shifts toward a pathological repair process. Here, we performed a transcriptional analysis of two major pro-fibrotic pathways, the TGF-β superfamily and Wnt signaling pathways to determine how they are differentially regulated during regenerative wound healing versus fibrosis in a lens injury model. For these studies, RNA sequencing was performed on an ex vivo lens explant system that models post-surgical healing within regenerative and fibrotic microenvironments, from 0 to 3 days post-injury. Fibrotic conditions …

Title:

Cardiopulmonary Bypass Facilitates Emergent TAVR and Bifurcation PCI in a Highly Comorbid 72-year-old Female with Acute Valvular Shock

Introduction:

Transcatheter aortic valve replacement (TAVR) has emerged as a critical minimally invasive option for patients with severe AS who present in valvular shock, particularly those at prohibitive surgical risk. Multicenter registry data demonstrate that emergent TAVR in this population is associated with promising procedural success, significant improvements in functional status, and lower short- and long-term mortality compared to medical management or balloon aortic valvuloplasty, with outcomes approaching those of surgical aortic valve replacement in selected patients [1] [2]. We present …

Acute Valve Syndrome And 1-Year All-Cause Mortality Post-Avr: A Retrospective Cohort Study, Omar Sale Bs, Nicholas Valle Do, Israa Saleh, Omar Jafar Md, Matthew Summers Md

Cardiovascular Research Symposium

Background: Acute Valve Syndrome (AVS) identifies a high-risk cohort of aortic stenosis (AS) patients with poor outcomes following aortic valve replacement (AVR), but the spectrum of risk within this group has yet to be fully explored. We sought to evaluate whether admission markers facilitated risk stratification of 1-year mortality in an AVS cohort.

Methods: In a retrospective cohort study (MIMIC-IV v3.1), we identified 2,380 adults who underwent AVR between 2008–2019. Patients were classified as AVS or progressive valvular disease (PVD). AVS was defined by criteria of acute decompensation, including advanced heart failure symptoms, cardiogenic shock, or significant hyperlactatemia. The AVS …
