Acute Respiratory Distress Syndrome, Holger K Eltzschig

Faculty, Staff and Student Publications

Acute Respiratory Distress Syndrome (ARDS) is defined as the rapid onset of non-cardiogenic pulmonary edema resulting in respiratory failure and hypoxemia. Efforts over the past 25 years, such as those of the ARDS and Prevention and Early Treatment of Acute Lung Injury (PETAL) Networks, have demonstrated a praiseworthy collaboration to further optimize the management of ARDS. However, improvements have been only moderate and ARDS remains a leading cause of mortality in the perioperative and critical care setting. Recently, the significant morbidity and mortality of ARDS have been emphasized by its high incidence in Coronavirus Disease 2019 (COVID-19) patients. A major …

The Gut Microbiome Contributes To Blood-Brain Barrier Disruption In Spontaneously Hypertensive Stroke Prone Rats, Joseph F Petrosino, David J Durgan, Robert M Bryan

Faculty, Staff and Students Publications

In recent years, it has become apparent that the gut microbiome can influence the functioning and pathological states of organs and systems throughout the body. In this study, we tested the hypothesis that the gut microbiome has a major role in the disruption of the blood-brain barrier (BBB) in the spontaneously hypertensive stroke prone rats (SHRSP), an animal model for hypertensive cerebral small vessel disease (CSVD). Loss of BBB is thought to be an early and initiating component to the full expression of CSVD in animal models and humans. To test this hypothesis, newly born SHRSP pups were placed with …

Prevalence Of Gastric Intestinal Metaplasia In A Multiethnic Us Veterans Population, Massimo Rugge, Aaron P Thrift, Hashem B El-Serag

Faculty, Staff and Students Publications

BACKGROUND & AIMS: There is a need to identify individuals with gastric intestinal metaplasia, a precursor to gastric cancer, so they can be offered screening and surveillance. We examined the prevalence of gastric intestinal metaplasia, detected by upper endoscopy biopsy analysis, in different race and ethnic subgroups. We also investigated the extent to which Helicobacter pylori infection, with or without acute and chronic gastritis, accounts for observed associations between race or ethnicity and risk of gastric intestinal metaplasia.

METHODS: We used data from a cross-sectional study of consecutively recruited patients at the Michael E. DeBakey Veterans Affairs Medical Center in …

Links Between Thrombosis And Inflammation In Traumatic Brain Injury, Rolando E Rumbaut

Faculty, Staff and Students Publications

Traumatic brain injury (TBI) continues to be a major healthcare problem and there is much to be explored regarding the secondary pathobiology to identify early predictive markers and new therapeutic targets. While documented changes in thrombosis and inflammation in major trauma have been well described, growing evidence suggests that isolated TBI also results in systemic alterations in these mechanisms. Here, we review recent experimental and clinical findings that demonstrate how blood-brain barrier dysfunction, systemic immune response, inflammation, platelet activation, and thrombosis contribute significantly to the pathogenesis of TBI. Despite advances in the links between thrombosis and inflammation, there is a …

Relation Of Magnetic Resonance Imaging Based Arterial Signal Enhancement To Markers Of Peripheral Artery Disease, Christina M Short, Addison A Taylor, Vijay Nambi, Joel D Morrisett, Christie M Ballantyne, Jean Bismuth, Dipan J Shah, Gerd Brunner

Faculty, Staff and Students Publications

Peripheral artery disease (PAD) is associated with impaired lower extremity function. We hypothesized that contrast-enhanced magnetic resonance imaging (CE-MRI) based arterial signal enhancement (SE) measures are associated with markers of PAD. A total of 66 participants were enrolled, 10 were excluded due to incomplete data, resulting in 56 participants for the final analyses (36 PAD, 20 matched controls). MR imaging was performed postreactive hyperemia using bilateral thigh blood-pressure cuffs. First pass-perfusion images were acquired at the mid-calf region with a high-resolution saturation recovery gradient echo pulse sequence, and arterial SE was measured for the lower extremity arteries. As expected, peak …

Agammaglobulinemia is the most profound primary antibody deficiency that can occur due to an early termination of B-cell development. We here investigated 3 novel patients, including the first known adult, from unrelated families with agammaglobulinemia, recurrent infections, and hypertrophic cardiomyopathy (HCM). Two of them also presented with intermittent or severe chronic neutropenia. We identified homozygous or compound-heterozygous variants in the gene for folliculin interacting protein 1 (FNIP1), leading to loss of the FNIP1 protein. B-cell metabolism, including mitochondrial numbers and activity and phosphatidylinositol 3-kinase/AKT pathway, was impaired. These defects recapitulated the Fnip1-/- animal model. Moreover, we identified either uniparental disomy …

Low muscle strength is an important heritable indicator of poor health linked to morbidity and mortality in older people. In a genome-wide association study meta-analysis of 256,523 Europeans aged 60 years and over from 22 cohorts we identify 15 loci associated with muscle weakness (European Working Group on Sarcopenia in Older People definition: n = 48,596 cases, 18.9% of total), including 12 loci not implicated in previous analyses of continuous measures of grip strength. Loci include genes reportedly involved in autoimmune disease (HLA-DQA1 p = 4 × 10

The Impact Of Hurricane Harvey On The Wellbeing Of Hospitalized Children And Their Families, Bryan J. Vonasek, Christopher Greeley, Claire Elizabeth Bocchini, Michelle Lopez

Journal of Applied Research on Children: Informing Policy for Children at Risk

Hurricane Harvey (HH) devastated Houston, Texas in August 2017. During October and November 2017, English speaking caregivers of hospitalized pediatric patients were surveyed on sociodemographic characteristics and how they were impacted by HH. One hundred caregivers were surveyed with 27% ‘severely impacted’ by HH. Approximately 75% of those severely impacted had a reported annual income ≤$50,000. Subjects in this lower income group were more likely to report increased worry about food for the household following HH and someone in the family losing their job due to HH. Those expressing that they were severely impacted by HH were more likely to …

New Insights And Enhanced Human Norovirus Cultivation In Human Intestinal Enteroids, Sue E Crawford, Frederick H Neill, Xi-Lei Zeng, Xiaomin Yu, B Vijayalakshmi Ayyar, Douglas Burrin, Sasirekha Ramani, Robert L Atmar, Mary K Estes

Faculty, Staff and Students Publications

Human noroviruses (HuNoVs) are the leading cause of epidemic and sporadic acute gastroenteritis worldwide. We previously demonstrated human intestinal stem cell-derived enteroids (HIEs) support cultivation of several HuNoV strains. However, HIEs did not support virus replication from every HuNoV-positive stool sample, which led us to test and optimize new medium conditions, identify characteristics of stool samples that allow replication, and evaluate consistency of replication over time. Optimization of our HIE-HuNoV culture system has shown the following: (i) a new HIE culture medium made with conditioned medium from a single cell line and commercial media promotes robust replication of HuNoV strains …

Many oncogenic insults deregulate RNA splicing, often leading to hypersensitivity of tumors to spliceosome-targeted therapies (STTs). However, the mechanisms by which STTs selectively kill cancers remain largely unknown. Herein, we discover that mis-spliced RNA itself is a molecular trigger for tumor killing through viral mimicry. In MYC-driven triple-negative breast cancer, STTs cause widespread cytoplasmic accumulation of mis-spliced mRNAs, many of which form double-stranded structures. Double-stranded RNA (dsRNA)-binding proteins recognize these endogenous dsRNAs, triggering antiviral signaling and extrinsic apoptosis. In immune-competent models of breast cancer, STTs cause tumor cell-intrinsic antiviral signaling, downstream adaptive immune signaling, and tumor cell death. Furthermore, RNA …

Decreased Inr On Lvad Support: To Bridge Or Not To Bridge?, Maya Guglin

The VAD Journal

In volume 6, issue 2 of The VAD Journal, we published a paper by Rainess et al. who reported their experience with managing subtherapeutic INRs, mostly in patients with HeartMate II (Thoratec, Pleasanton, CA). Although, the cohort did include some HeartMate 3-supported patients. In their program (Wake Forest University), pharmacists manage anticoagulation according to the institutional protocol, which allows bridging with low molecular weight heparin when INR decreases to less than 1.8. The study is unique because the patients did NOT require interruption of anticoagulation for any purpose. In all instances, the INR decreased because of dietary variations, recent …

Faculty, Staff and Students Publications

BACKGROUND: In August 2017, Hurricane Harvey caused unprecedented flooding across the greater Houston area. Given the potential for widespread flood-related exposures, including mold and sewage, and the emotional and mental toll caused by the flooding, we sought to evaluate the short- and long-term impact of flood-related exposures on the health of Houstonians. Our objectives were to assess the association of flood-related exposures with allergic symptoms and stress among Houston-area residents at two time points: within approximately 30 days (T1) and 12 months (T2) after Hurricane Harvey's landfall.

METHODS: The Houston Hurricane Harvey Health (Houston-3H) Study enrolled a total of 347 …

An Economic And Disease Transmission Model Of Human Papillomavirus And Oropharyngeal Cancer In Texas, Li Xu, Shuangshuang Fu, Wenyaw Chan, Erich M Sturgis, Lois M Ramondetta, Libin Rong, David R Lairson, Hongyu Miao

Faculty, Staff and Student Publications

In 2017, 46,157 and 3,127 new oropharyngeal cancer (OPC) cases were reported in the U.S. and Texas, respectively. About 70% of OPC were attributed to human papillomavirus (HPV). However, only 51% of U.S. and 43.5% of Texas adolescents have completed the HPV vaccine series. Therefore, modeling the demographic dynamics and transmission of HPV and OPC progression is needed for accurate estimation of the economic and epidemiological impacts of HPV vaccine in a geographic area. An age-structured population dynamic model was developed for the U.S. state of Texas. With Texas-specific model parameters calibrated, this model described the dynamics of HPV-associated OPC …

Advantages Of Bridging To Durable Left Ventricular Assist Device With The Impella 5.0, Manish K. Patel

The VAD Journal

The mainstay therapy for patients in critical cardiogenic shock (CS) is temporary mechanical circulatory support. Although there is a trend toward use of durable left ventricular assist devices (LVAD) in patients that are less ill, we present our experience with using the Impella 5.0 (Abiomed) to illustrate the potential benefits of supporting patients with critical CS before durable LVAD implantation. Since 2012, our use of the Impella has increased from 5 to 38 per year. Mortality is highest early after LVAD implantation, but our long-term survival is better than data reported to the INTERMACS registry. Use of an Impella 5.0 …

Multicomponent lipid emulsions are available for critical care of preterm infants. We sought to determine the impact of different lipid emulsions on early priming of the host and its response to an acute stimulus. Pigs delivered 7d preterm (n = 59) were randomized to receive different lipid emulsions for 11 days: 100% soybean oil (SO), mixed oil emulsion (SO, medium chain olive oil and fish oil) including 15% fish oil (MO15), or 100% fish oil (FO100). On day 11, pigs received an 8-h continuous intravenous infusion of either lipopolysaccharide (LPS—lyophilized Escherichia coli) or saline. Plasma was collected for …

A "Blinking" Left Ventricular Assist Device, Maya Guglin, Roopa Rao

The VAD Journal

A 61-year-old male with history of coronary artery disease and end stage ischemic cardiomyopathy underwent a successful implantation of a HeartMate 3 device with an uneventful recovery. However, after 6 months, he complained of increased fatigue, intermittent dizziness, and weakness after minor exertion. The pulsatility index was increased to 8, but the left ventricular assist device (LVAD) was otherwise functioning properly. No major changes in either medications or laboratory results were noted. The patient started getting low flow alarms seven months after the procedure and the dizziness increased. On the controller, a continuously changing (“blinking”) speed was noted (Supplemental Video …

Central Nervous System Intravascular Lymphoma Leading To Rapidly Progressive Dementia, S Richard Dunham, Karen Nunez-Wallace, Shital M Patel, Priti Dangayach, Stephanie Holdener, Weei-Chin Lin

Faculty, Staff and Students Publications

Intravascular lymphoma is an uncommon subtype of B-cell lymphoma with neoplastic cells limited to the lumen of small blood vessels. We report a case of a 52-year-old man who presented with constitutional symptoms and rapidly progressive dementia. He was found to have diffuse leptomeningeal and faint parenchymal enhancement on magnetic resonance imaging and was subsequently diagnosed with intravascular lymphoma following a brain biopsy. He responded remarkably well to systemic and intrathecal chemotherapy. The diagnosis and treatment of intravascular lymphoma have been guided by a few case reports and are largely based on expert opinion.

Plasmid-Based Reverse Genetics For Probing Phosphorylation-Dependent Viroplasm Formation In Rotaviruses

Faculty, Staff and Students Publications

Rotavirus (RV) replication occurs in cytoplasmic compartments, known as viroplasms, that are composed of viral and cellular proteins. Viroplasm formation requires RV nonstructural proteins NSP2 and NSP5 and cellular lipid droplets (LDs); however, the mechanisms required for viroplasm assembly remain largely unknown. We previously identified two conformationally-distinct forms of NSP2 (dNSP2, vNSP2) found in RV-infected cells that interact differentially with hypo- and hyperphosphorylated NSP5, respectively, and indicate a coordinated phosphorylation-dependent mechanism regulating viroplasm assembly. We also reported that phosphorylation of dNSP2 on serine 313 by the cellular kinase CK1α triggers the localization of vNSP2 to sites of viroplasm assembly and …
