BACKGROUND: COVID-19 convalescent plasma (CCP) is an important therapeutic option for outpatients at high risk of hospitalization from SARS-CoV-2 infection. We assessed the safety of outpatient CCP transfusions administered during clinical trials.

STUDY DESIGN AND METHODS: We analyzed data pertaining to transfusion-related reactions from two randomized controlled trials in the U.S. that evaluated the efficacy of CCP versus control plasma in various ambulatory settings. Multivariable logistic regression was used to assess whether CCP was associated with transfusion reactions, after adjusting for potential confounders.

RESULTS: The combined study reported 79/1351 (5.9%) adverse events during the transfusion visit, with the majority 62/1351 …

Polygenic Genetic Variation Affecting Antibody Formation Underlies Hypertensive Renal Injury In The Stroke-Prone Spontaneously Hypertensive Rat, Isha S Dhande, Yaming Zhu, Aniket S Joshi, M John Hicks, Michael C Braun, Peter A Doris

Faculty, Staff and Students Publications

During development of the spontaneously hypertensive rat (SHR), several distinct but closely related lines were generated. Most lines are resistant to hypertensive renal disease. However, the SHR-A3 line (stroke-prone SHR) experiences end-organ injury (EOI) and provides a model of injury susceptibility that can be used to uncover genetic causation. In the present study, we generated a congenic line in which three distinct disease loci in SHR-A3 are concurrently replaced with homologous loci from an injury-resistant SHR line (SHR-B2). Verification that all three loci were homozygously replaced in this triple congenic line [SHR-A3(Trip B2)] while the genetic background of SHR-A3 was …

Myths And Methodologies: Cardiopulmonary Exercise Testing For Surgical Risk Stratification In Patients With An Abdominal Aortic Aneurysm; Balancing Risk Over Benefit, Damian M Bailey, Richard G Davies, George A Rose, Michael H Lewis, Ahmed Abd Aldayem, Chistopher P Twine, Wael Awad, Matti Jubouri, Idhrees Mohammed, Carlos A Mestres, Edward P Chen, Joseph S Coselli, Ian M Williams, Mohamad Bashir, International Academic Surgical Consortium (Thalamus)

Faculty, Staff and Students Publications

The extent to which patients with an abdominal aortic aneurysm (AAA) should exercise remains unclear, given theoretical concerns over the perceived risk of blood pressure-induced rupture, which is often catastrophic. This is especially pertinent during cardiopulmonary exercise testing, when patients are required to perform incremental exercise to symptom-limited exhaustion for the determination of cardiorespiratory fitness. This multimodal metric is being used increasingly as a complementary diagnostic tool to inform risk stratification and subsequent management of patients undergoing AAA surgery. In this review, we bring together a multidisciplinary group of physiologists, exercise scientists, anaesthetists, radiologists and surgeons to challenge the enduring …

New Records Of Ornithodoros Turicata (Ixodida: Argasidae) In Rural And Urban Sites In The Mexican States Of Aguascalientes And Zacatecas Indicate The Potential For Tick-Borne Relapsing Fever, Edwin Vázquez-Guerrero, José Luis González-Quiroz, María Lilia Domínguez-López, Alexander R Kneubehl, Aparna Krishnavajhala, Michael W Curtis, Alejandro Ponce-Mendoza, Paulina Estrada-De Los Santos, Job E Lopez, J Antonio Ibarra

Faculty, Staff and Students Publications

Soft ticks from the Ornithodoros genus are vectors of relapsing fever (RF) spirochetes around the world. In Mexico, they were originally described in the 19th century. However, few recent surveillance studies have been conducted in Mexico, and regions where RF spirochetes circulate remain vague. Here, the presence of soft ticks in populated areas was assessed in two sites from the Mexican states of Aguascalientes and Zacatecas. Argasidae ticks were collected, identified by morphology and mitochondrial 16S rDNA gene sequencing, and tested for RF borreliae. The specimens in both sites were identified as Ornithodoros turicata but no RF spirochetes were detected. …

Loss Of Stearoyl-Coa Desaturase 2 Disrupts Inflammatory Response In Macrophages, Joseph B Lin, Amy Mora, Tzu Jui Wang, Andrea Santeford, Darksha Usmani, Marianne M Ligon, Indira U Mysorekar, Rajendra S Apte

Faculty, Staff and Students Publications

Macrophages are innate immune cells that patrol tissues and are the first responders to detect infection. They orchestrate the host immune response in eliminating invading pathogens and the subsequent transition from inflammation to tissue repair. Macrophage dysfunction contributes to age-related pathologies, including low-grade inflammation in advanced age that is termed "inflammaging." Our laboratory has previously identified that macrophage expression of a fatty acid desaturase, stearoyl-CoA desaturase 2 (SCD2), declines with age. Herein, we delineate the precise cellular effects of SCD2 deficiency in murine macrophages. We found that deletion of

While pediatric COVID-19 is rarely severe, a small fraction of children infected with SARS-CoV-2 go on to develop multisystem inflammatory syndrome (MIS-C), with substantial morbidity. An objective method with high specificity and high sensitivity to identify current or imminent MIS-C in children infected with SARS-CoV-2 is highly desirable. The aim was to learn about an interpretable novel cytokine/chemokine assay panel providing such an objective classification. This retrospective study was conducted on four groups of pediatric patients seen at multiple sites of Texas Children's Hospital, Houston, TX who consented to provide blood samples to our COVID-19 Biorepository. Standard laboratory markers of …

Class-Driven Synergy And Antagonism Between A Pseudomonas Phage And Antibiotics, Paul Nicholls, Justin R Clark, Carmen Gu Liu, Austen Terwilliger, Anthony W Maresso

Faculty, Staff and Students Publications

The ubiquitous bacterial pathogen Pseudomonas aeruginosa is responsible for severe infections in patients with burns, cystic fibrosis, and neutropenia. Biofilm formation gives physical refuge and a protected microenvironment for sessile cells, rendering cure by antibiotics a challenge. Bacteriophages have evolved to prey on these biofilms over millions of years, using hydrolases and depolymerases to penetrate biofilms and reach cellular targets. Here, we assessed how a newly discovered KMV-like phage (ΦJB10) interacts with antibiotics to treat P. aeruginosa more effectively in both planktonic and biofilm forms. By testing representatives of four classes of antibiotics (cephalosporins, aminoglycosides, fluoroquinolones, and carbapenems), we demonstrated …

The development of SARS-CoV-2 main protease (Mpro) inhibitors for the treatment of COVID-19 has mostly benefitted from X-ray structures and preexisting knowledge of inhibitors; however, an efficient method to generate Mpro inhibitors, which circumvents such information would be advantageous. As an alternative approach, we show here that DNA-encoded chemistry technology (DEC-Tec) can be used to discover inhibitors of Mpro. An affinity selection of a 4-billion-membered DNA-encoded chemical library (DECL) using Mpro as bait produces novel non-covalent and non-peptide-based small molecule inhibitors of Mpro with low nanomolar Ki values. Furthermore, these compounds demonstrate efficacy against mutant forms of Mpro that …

Fecal microbiota transplantation (FMT) has proven to be an effective treatment for recurrent Clostridioides difficile infection (rCDI) in both adult and pediatric patients. However, as microbiome development is a critical factor in children, it remains unclear whether adult fecal donors can provide age-appropriate functional restoration in pediatric patients. To address this issue, we conducted an integrated systems approach and found that concordant donor strain engraftment, along with metabolite restoration, are associated with FMT outcomes in both adult and pediatric rCDI patients. Although functional restoration after FMT is not strain-specific, specialized metabolic functions are retained in pediatric patients when adult fecal …

Comparison Of Random Urine Protein/Creatinine Ratio With 24-Hour Urine Protein In Suspected Pre-Eclampsia, Lily Olayinka, Emily Garnett, Brian Burnett, Sridevi Devaraj

Faculty, Staff and Students Publications

INTRODUCTION: Proteinuria is one of the classical criteria for the diagnosis of pre-eclampsia. The gold standard remains the measurement of 24-h urine protein which is time consuming and prone to preanalytical errors. Random urine protein creatinine ratio (UPCR) is endorsed by clinical practice guidelines as a faster alternative. The aim of this study was to evaluate the correlation between the 24-h urine protein excretion and UPCR in the identification of proteinuria in suspected preeclamptic patients.

METHOD: A total of 51 women with suspected pre-eclampsia from the maternal fetal clinic of our institution were retrospectively studied. The correlation between the UPCR …

BACKGROUND: Immune checkpoint inhibitors have revolutionized cancer treatment. However, they are associated with a unique spectrum of side effects, called immune-related adverse events (irAEs), which can cause significant morbidity and quickly progress to severe or life-threatening events if not treated promptly. Identifying predictive biomarkers for irAEs before immunotherapy initiation is therefore a critical area of research. Polymorphisms within the T-cell receptor beta (TCRB) variable (TRBV) gene have been implicated in autoimmune disease and may be mechanistically linked to irAEs. However, the repetitive nature of the TCRB locus and incomplete genome assembly has hampered the evaluation of TRBV polymorphisms in the …

Faculty, Staff and Students Publications

Osteosarcoma is the most frequent primary malignant bone tumor with an annual incidence of about 400 cases in the United States. Osteosarcoma primarily metastasizes to the lungs, where FAS ligand (FASL) is constitutively expressed. The interaction of FASL and its cell surface receptor, FAS, triggers apoptosis in normal cells; however, this function is altered in cancer cells. DNA methylation has previously been explored as a mechanism for altering FAS expression, but no variability was identified in the CpG island (CGI) overlapping the promoter. Analysis of an expanded region, including CGI shores and shelves, revealed high variability in the methylation of …

Nanoparticle-Mediated Therapy With Mir-198 Sensitizes Pancreatic Cancer To Gemcitabine Treatment Through Downregulation Of Vcp-Mediated Autophagy, Christian Marin-Muller, Dali Li, Jian-Ming Lü, Zhengdong Liang, Osvaldo Vega-Martínez, Sue E Crawford, Mary K Estes, William E Fisher, Changyi Chen, Qizhi Yao

Faculty, Staff and Students Publications

Pancreatic ductal adenocarcinoma (PDAC) remains an extremely aggressive disease characterized by rapidly acquired multi-drug resistance, including to first-line chemotherapeutic agent gemcitabine. Autophagy is a process that is often exploited by cancer and is one of several intrinsic factors associated with resistance to gemcitabine. We have previously found that miR-198 acts as a tumor suppressor in PDAC through the targeting of factors including Valosin-containing protein (VCP). VCP has been reported to play an important role in autophagic flux. In this study, we investigated whether the repression of VCP through miR-198 administration disrupts the autophagy process and sensitizes PDAC cells to gemcitabine …
