Incubation With Porcine Urinary Bladder Matrix Yields A Late-Stage Wound Transcriptome In Endothelial Cells And Keratinocytes Isolated From Both Diabetic And Non-Diabetic Subjects, John T. Paige, Daniel J. Lightell, Hunter F. Douglas, Natasha C. Klingenberg, Thaidan Pham, T. Cooper Woods Jun 2023

Incubation With Porcine Urinary Bladder Matrix Yields A Late-Stage Wound Transcriptome In Endothelial Cells And Keratinocytes Isolated From Both Diabetic And Non-Diabetic Subjects, John T. Paige, Daniel J. Lightell, Hunter F. Douglas, Natasha C. Klingenberg, Thaidan Pham, T. Cooper Woods

School of Medicine Faculty Publications

Proper wound closure requires the functional coordination of endothelial cells (ECs) and keratinocytes. In the late stages of wound healing, keratinocytes become activated and ECs promote the maturation of nascent blood vessels. In diabetes mellitus, decreased keratinocyte activation and impaired angiogenic action of ECs delay wound healing. Porcine urinary bladder matrix (UBM) improves the rate of wound healing, but the effect of exposure to UBM under diabetic conditions remains unclear. We hypothesized that keratinocytes and ECs isolated from both diabetic and non-diabetic donors would exhibit a similar transcriptome representative of the later stages of wound healing following incubation with UBM. …

Association Of Prematurity And Urogenital Comorbidities With Postoperative Outcomes Of Ureteroneocystostomy For Vesicoureteral Reflux, Raeann Dalton, Young Son, Edward Wu, Leah Anderton, Matthew Eximond, Lance Earnshaw, Katelyn Klimowich, Gregory Dean

Rowan-Virtua Research Day

Background: It is estimated that 20-30% of congenital anomalies involve the kidney and ureter, and these rates are even higher in infants with low birth weights. Vesicoureteral reflux (VUR) occurs when there is a backflow of urine from the bladder to the kidney. Depending on severity, this condition may require surgical correction with ureteroneocystostomy (UNC). The impact of premature birth and presence of urogenital comorbidities on outcomes of UNC is not known. The objective of this study is to determine the relationship between premature birth and urogenital comorbidities with operative outcomes of UNC for VUR.

Methods: The 2020 American College …

Thrompella: Acute Impella Thrombosis During Ecpella Support, Faris Araj, Hurst M. Hall, Amy E. Hackmann

The VAD Journal

We present a case of acute Impella thrombosis during Ecpella support in a 48-year-old man listed for a heart transplant. After two weeks of Ecpella support, echocardiography revealed a 2.6 x 1.1 cm mobile thrombus attached to the Impella inlet (Video). The Impella and attached thrombus were pulled across the aortic valve into the descending aorta and removed without systemic thromboembolism. Due to the ongoing need for left ventricular venting, a new Impella CP was placed.


Quality Assurance In Extracorporeal Membrane Oxygenation Patients, Ruzica Mrkonjic Apr 2023

Quality Assurance In Extracorporeal Membrane Oxygenation Patients, Ruzica Mrkonjic

The VAD Journal

The selection of patients for extracorporeal membrane oxygenation (ECMO) support is a critical component of any perfusion program. Teams must evaluate when to start the support, how long to support the patient, and when is the ideal time to wean. The timing of ECMO support is debated. While some programs emphasize prompt timing, others suggest the conservative approach is better (>7 hours). Delaying ECMO support could increase complications; thus, more evidence has been attained for prompt support. Importantly, complications are common with ECMO support. Despite advances in ECMO support over the last ten years, bleeding remains a high risk. …

Department of Biological & Biomedical Sciences

DPP8/9 inhibition induces either pyroptotic or apoptotic cell death in hematological malignancies. We previously reported that treatment with the DPP8/9 inhibitor 1G244 resulted in apoptotic cell death in myeloma, and our current study further evaluates the mechanism of action of 1G244 in different blood cancer cell lines. Specifically, 1G244 inhibited DPP9 to induce GSDMD-mediated-pyroptosis at low concentrations and inhibited DPP8 to cause caspase-3-mediated-apoptosis at high concentrations. HCK expression is necessary to induce susceptibility to pyroptosis but does not participate in the induction of apoptosis. To further characterize this DPP8-dependent broad-spectrum apoptosis induction effect, we evaluated the potential antineoplastic role for …

Delayed Thoracodorsal Artery Perforator Free Flap For Calcaneal Degloving Injury Reconstruction, Mallorie L. Huff, Ahmed M. Mansour, Mamtha S. Raj, Robert J. Allen, Sean J. Wallace

School of Medicine Faculty Publications

The thoracodorsal artery perforator (TDAP) flap has a long vascular pedicle that is ideal for lower extremity reconstruction, but it generally relies on the presence of a dominant septocutaneous perforator vessel. Surgical delay optimizes flap survival by creating relative ischemia to augment perforator vessels. In this report, we describe the use of a delayed free TDAP flap in the setting of an absent dominant perforator vessel for the reconstruction of a calcaneal degloving injury. A 22-year-old actively smoking patient with a body mass index of 33.5 presented with a nonhealing left heel wound with overlying necrotic changes after traumatic degloving …

Greenwood, Candace Fanale, Cody Gustaveson, Brian Jaski, Hirsch S. Mehta, Peter Hoagland, Kristine Ortiz, Marc Verlasky, Robert Adamson, Walter Dembitsky

The VAD Journal

Objective: Durable mechanical circulatory support is a proven therapy to extend survival for patients with end-stage heart failure (HF). The International Society for Heart and Lung Transplantation guidelines recommend a detailed psychosocial assessment when selecting candidates for durable mechanical circulatory support. Currently, there are no formally validated psychosocial evaluation tools for left ventricular assist device (LVAD) candidacy. The Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) uses a multidisciplinary algorithm to evaluate the impact of pre-transplant risk factors on post-transplant outcomes. Emerging literature suggests that the SIPAT might be useful for assessing psychosocial risk factors for LVAD outcomes.

Left Atrial Veno-Arterial Extracorporeal Membrane Oxygenation (Lava-Ecmo): Percutaneous Bi-Atrial Drainage To Avoid Pulmonary Edema In A Patient With Left Ventricular Systolic Dysfunction, Kenneth R. Dulnuan, Joseph B. Zwischenberger, John G. Gurley, Maya Guglin

The VAD Journal

Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is used in patients with severe cardiogenic shock refractory to medical therapy. During V-A ECMO, retrograde flow in the aorta towards the left ventricle (LV) causes increased left-sided filling pressures, which may lead to pulmonary edema. Different strategies have been proposed to decompress the left heart, including placement of an intraaortic balloon pump (IABP), Impella® (Abiomed), or TandemHeart® (Cardiac Assist). Percutaneous decompression of the left atrium via placement of a transseptal cannula incorporated into the existing venous limb had also been previously done. We describe the novel use of the VFEM venous femoral cannula …

The VAD Journal

The use of a left ventricular assist device has increased and is a primary surgical treatment for heart failure. However, one major complication of left ventricular assist device support is an obstruction in the blood flow pathway. Pump thrombosis and outflow graft occlusion are some of the common causes of such obstructions. Here, we describe a unique case of HeartMate II (Abbott Laboratories) inflow cannula obstruction from a membranous structure without evidence of thrombus. The histology showed evidence of fibrous tissue and heart muscle tissue in the membrane. The patient underwent a successful device exchange with a HeartMate 3 (Abbott …


Intra-Aortic Balloon Pump May Attenuate Adverse Hemodynamic Effects Of Negative Intrathoracic Pressure In Cardiogenic Shock, Faris Araj Sep 2022

Intra-Aortic Balloon Pump May Attenuate Adverse Hemodynamic Effects Of Negative Intrathoracic Pressure In Cardiogenic Shock, Faris Araj

The VAD Journal

High negative intrathoracic pressure (NIP), as occurs during obstructive sleep apnea or hiccups, results in adverse hemodynamic consequences, specifically a decrease in left ventricle (LV) performance. These untoward effects can potentially be catastrophic in the case of an already compromised LV in cardiogenic shock. The interplay of intra-aortic balloon pump counter pulsation during abrupt high NIP in cardiogenic shock is described.
