Injectable Hydrogel Electrodes As Conduction Highways To Restore Native Pacing, Gabriel J Rodriguez-Rivera, Allison Post, Mathews John, Skylar Buchan, Drew Bernard, Mehdi Razavi, Elizabeth Cosgriff-Hernandez

Faculty, Staff and Students Publications

There is an urgent clinical need for a treatment regimen that addresses the underlying pathophysiology of ventricular arrhythmias, the leading cause of sudden cardiac death. The current report describes the design of an injectable hydrogel electrode and successful deployment in a pig model with access far more refined than any current pacing modalities allow. In addition to successful cardiac capture and pacing, analysis of surface ECG tracings and three-dimensional electroanatomic mapping revealed a QRS morphology comparable to native sinus rhythm, strongly suggesting the hydrogel electrode captures the deep septal bundle branches and Purkinje fibers. In an ablation model, electroanatomic mapping …

Is Long-Term Survival Higher In Patients Who Receive Propofol-Based Total Intravenous Anesthesia During Colorectal Cancer Surgery Compared To Volatile Anesthesia, Shad Anthony Mitchell

Theses, Dissertations and Capstones

The study reviewed several retrospective cohort studies that examined the impact of propofol-based total intravenous anesthesia (TIVA) versus volatile anesthesia (VA) on the long-term survival of colorectal cancer (CRC) surgery patients. Eight studies found no significant difference in mortality between the two anesthesia types, while three studies indicated a significant decrease in all-cause mortality favoring propofol TIVA. The studies had varying follow-up periods, with some extending to five years. Notably, two studies controlled the type of volatile anesthetic used, specifically sevoflurane and desflurane. The findings suggest a potential survival advantage for propofol TIVA, warranting further investigation.

Antiseptic preparation of surgical sites is known to reduce the rate of infective complications. However, surgical site infections (SSI) remain a leading cause of post-operative hospitalizations, increasing patient stress and cost for the healthcare system.1-7 In gynecologic surgery, preparation of the vagina is performed to reduce bacterial load prior to surgery, though it is known to remain contaminated.3 In the US, only solutions containing povidone-iodine (PI) are FDA approved for vaginal preparation; though, a 2018 ACOG Practice Bulletin lists chlorhexidine gluconate (CHG) with low (<4%) alcohol concentrations as a reasonable option for off-label use.3 Other preparations for vaginal surgery have been reported including baby shampoo (BS) and a commercially available preparation, containing PCMX (para-chloro-meta-xylenol, Techni-care®, chloroxylenol), that is marketed specifically for use with mucous membranes.8-12 There is a growing need to establish evidence-based alternatives to iodine for vaginal preparation for patients with allergies or sensitivity to iodine-containing products while minimizing postoperative irritation. One retrospective study comparing BS to PI in gynecologic surgeries showed a non-significant lower rate of surgical site infection with BS.9 One major challenge for determining effectiveness of surgical scrubs for reducing SSI is the relatively rare occurrence of postoperative infection. As an alternative proxy for infection colony counts of bacteria/fungi, before and after preparation, have been used.12,13 BS has been shown to reduce bacterial loads in non-gynecologic surgery, but there is limited data regarding its use in vaginal surgery, even though surgeons have been using BS in cases of iodine allergy or intolerance to other antiseptics.9-12CHG use in vaginal surgery has been debated due to concerns about vaginal irritation, however studies have demonstrated that alteration of the solution to 2-4% chlorhexidine with low (4%) alcohol concentration was associated with mild to no vaginal irritation. CHG showed similar reduction in post-incision bacterial counts and wound infections in cesarean delivery, and reduced colony counts during hysterectomy (when compared to PI).14-20 PCMX and CHG were shown to significantly reduce bacterial colonization of extracted root canals, and PCMX has been marketed specifically for vaginal antiseptic preparation.21 While some information on the effectiveness of these four antiseptic preparations has been documented in the literature, at this time there are no randomized controlled trials comparing these solutions in the context of vaginal surgery. Further evaluation and research of antiseptic solutions is warranted to provide evidence for best practices in minimizing infection and irritation. The purpose of this study was to compare the effectiveness of three antiseptic solutions with the standard, PI, for reducing bacterial colonies as a proxy for SSI, and to assess postoperative irritation and infection symptoms.

Metabolism Shapes Immune Responses To Staphylococcus Aureus., Prabhakar Arumugam, Tammy Kielian

Journal Articles: Pathology and Microbiology

BACKGROUND: Staphylococcus aureus (S. aureus) is a common cause of hospital- and community-acquired infections that can result in various clinical manifestations ranging from mild to severe disease. The bacterium utilizes different combinations of virulence factors and biofilm formation to establish a successful infection, and the emergence of methicillin- and vancomycin-resistant strains introduces additional challenges for infection management and treatment.

SUMMARY: Metabolic programming of immune cells regulates the balance of energy requirements for activation and dictates pro- versus anti-inflammatory function. Recent investigations into metabolic adaptations of leukocytes and S. aureus during infection indicate that metabolic crosstalk plays a crucial role in …

Elucidating Granulocytic Myeloid-Derived Suppressor Cell Heterogeneity During Staphylococcus Aureus Biofilm Infection, Blake P. Bertrand, Cortney E. Heim, Scott A. Koepsell, Tammy Kielian

Journal Articles: Pathology and Microbiology

Myeloid-derived suppressor cells (MDSCs) are pathologically activated immature myeloid cells with immunosuppressive activity that expand during chronic inflammation, such as cancer and prosthetic joint infection (PJI). Myeloid-derived suppressor cells can be broadly separated into 2 populations based on surface marker expression and function: monocytic myeloid-derived suppressor cells (M-MDSCs) and granulocytic myeloid-derived suppressor cells (G-MDSCs). Granulocytic myeloid-derived suppressor cells are the most abundant leukocyte infiltrate during PJI; however, how this population is maintained in vivo and cellular heterogeneity is currently unknown. In this study, we identified a previously unknown population of Ly6G+Ly6C+F4/80+MHCII+ MDSCs during PJI that displayed immunosuppressive properties ex vivo. …

Antimicrobial Activity Of Gallium(Iii) Compounds: Pathogen-Dependent Targeting Of Multiple Iron/Heme-Dependent Biological Processes, Seoung-Ryoung Choi, Mohammed A. Hassan, Bradley E. Britigan, Prabagaran Narayanasamy

Journal Articles: Pathology and Microbiology

Metals play vital roles in biological systems, with iron/heme being essential for cellular and metabolic functions necessary for survival and/or virulence in many bacterial pathogens. Given the rise of bacterial resistance to current antibiotics, there is an urgent need for the development of non-toxic and novel antibiotics that do not contribute to resistance to other antibiotics. Gallium, which mimics iron, has emerged as a promising antimicrobial agent, offering a novel approach to combat bacterial infections. Gallium does not have any known functions in biological systems. Gallium exerts its effects primarily by replacing iron in redox enzymes, effectively inhibiting bacterial growth …

Background: Environmental lipopolysaccharide (LPS) and microbial component-enriched organic dusts cause significant lung disease. These environmental exposures induce the recruitment and activation of distinct lung monocyte/macrophage subpopulations involved in disease pathogenesis. Aconitate decarboxylase 1 (Acod1) was one of the most upregulated genes following LPS (vs. saline)exposure of murine whole lungs with transcriptomic profiling of sorted lung monocyte/macrophage subpopulations also highlighting its significance. Given monocyte/macrophage activation can be tightly linked to metabolism, the objective of these studies was to determine the role of the immunometabolic regulator ACOD1 inenvironmentalexposure-induced lung inflammation.

The Impact Of Local Physiology On The Corrosion Of Orthopedic Alloys, Madison Nicole Brown

Theses and Dissertations (ETD)

Introduction. Total knee arthroplasty (TKA) is used in the treatment of end-stage osteoarthritis of the knee. It is one of the most common elective surgeries performed with predictions expecting significant increases in the number of procedures performed over the next decade. However, the patient satisfaction rate after TKA is as low as 80%. Cobalt-chromium-molybdenum (CoCrMo) is regularly used for TKA protheses due to the alloy’s mechanical strength, biocompatibility, and corrosion resistance. The corrosion resistance of this alloy relies on a passive oxide layer. This oxide layer can be impacted by phagocytic cells which can leave pits and craters on implant …
