Prevalence Of Sensorineural Hearing Loss In Children With Palliated Or Repaired Congenital Heart Disease., Lalitha Gopineti, Mane Paulpillai, Andrea Rosenquist, Andrew H. Van Bergen

Manuscripts, Articles, Book Chapters and Other Papers

Background Children with congenital heart disease (CHD) are at increased risk of neurodevelopmental deficits, and the presence of sensorineural hearing loss (SNHL) may further lead to poor language skills acquisition and speech delays. Prevalence of SNHL in the general pediatric population is estimated to be 0.2% at birth to 0.35% during adolescence. Very few studies have attempted to estimate SNHL prevalence in children who have undergone congenital heart surgery. Methods This retrospective study aimed to estimate SNHL prevalence in children who underwent congenital heart surgery in our institution and were followed up in our high-risk pediatric cardiology clinics for four …

Grk6 Regulates The Hemostatic Response To Injury Through Its Rate-Limiting Effects On Gpcr Signaling In Platelets., Xi Chen, Shuchi Gupta, Matthew Cooper, Daniel Dehelian, Xuefei Zhao, Meghna U.

G protein-coupled receptors (GPCRs) mediate the majority of platelet activation in response to agonists. However, questions remain regarding the mechanisms that provide negative feedback toward activated GPCRs to limit platelet activation and thrombus formation. Here we provide the first evidence that GPCR kinase 6 (GRK6) serves this role in platelets, using GRK6-/- mice generated by CRISPR-Cas9 genome editing to examine the consequences of GRK6 knockout on GPCR-dependent signaling. Hemostatic thrombi formed in GRK6-/- mice are larger than in wild-type (WT) controls during the early stages of thrombus formation, with a rapid increase in platelet accumulation at the site of injury. …

The Need For A Physical Therapy Clinic In Pucallpa, Peru, Isabella M. Sutton, Abby M. Waldek, Brylie M. Wiedmaier

All Electronic Theses and Dissertations

In developing countries, complications from traumatic injuries account for a significantly higher number of deaths annually compared to developed countries. Not only are traumatic injuries more likely to occur in developing countries, but limited access to quality healthcare and adequate funds to pay for services make it much more likely for individuals to be left with lifelong disabilities. With that, this community service project worked with Scalpel at the Cross (SATC), an orthopedic medical ministry based in Pucallpa, Peru to expand their ability to provide free orthopedic surgeries and physical therapy following traumatic injuries. The community service project will help …

Journal Articles

This article is protected by copyright. All rights reserved. A hallmark of severe COVID-19 is coagulopathy, with 71.4% of patients who die of COVID-19 meeting ISTH criteria for disseminated intravascular coagulation (DIC) while only 0.6% of patients who survive meet these criteria (1). Additionally, it has become clear that this is not a bleeding diathesis but rather a predominantly pro-thrombotic DIC with high venous thromboembolism rates, elevated D-dimer levels, high fibrinogen levels in concert with low anti-thrombin levels, and pulmonary congestion with microvascular thrombosis and occlusion on pathology in addition to mounting experience with high rates of central line thrombosis …

Two-Needle Technique For Lumbar Radiofrequency Medial Branch Denervation: A Technical Note, K. B. Chapman, F. Schirripa, T. Oud, P. S. Groenen, R. R. Ramsook, N. Van Helmond

Journal Articles

© 2020, American Society of Interventional Pain Physicians. All rights reserved. Background: Radiofrequency ablation (RFA) of the medial branches of the dorsal rami has been reported to relieve facet joint–related back pain for 6 months to 1 year in 60% of patients. Although providing benefit in a significant proportion of patients, there remains a group of patients who do not experience any pain relief from RFA or experience only benefit from the ablation for a short period. Failure of RFA has been attributed to technical failure of coagulating the nerve or coagulation of a minimal section of the nerve, allowing …

Gut Microbiota Metabolite Fights Against Dietary Polysorbate 80-Aggravated Radiation Enteritis, Y. Li, H. Xiao, J. Dong, D. Luo, H. Wang, S. Zhang, T. Zhu, C. Zhu, M. Cui, S. Fan

Journal Articles

© Copyright © 2020 Li, Xiao, Dong, Luo, Wang, Zhang, Zhu, Zhu, Cui and Fan. Radiation therapy is a cornerstone of modern management methods for malignancies but is accompanied by diverse side effects. In the present study, we showed that food additives such as polysorbate 80 (P80) exacerbate irradiation-induced gastrointestinal (GI) tract toxicity. A 16S ribosomal RNA high-throughput sequencing analysis indicated that P80 consumption altered the abundance and composition of the gut microbiota, leading to severe radiation-induced GI tract injury. Mice harboring fecal microbes from P80-treated mice were highly susceptible to irradiation, and antibiotics-challenged mice also represented more sensitive to …

Time To Develop Therapeutic Antibodies Against Harmless Proteins Colluding With Sepsis Mediators?, J. Li, G. Bao, H. Wang

Journal Articles

Sepsis refers to a systemic inflammatory response syndrome resulting from microbial infections, and is partly attributable to dysregulated inflammation and associated immunosuppression. A ubiquitous nuclear protein, HMGB1, is secreted by activated leukocytes to orchestrate inflammatory responses during early stages of sepsis. When it is released by injured somatic cells at overwhelmingly higher quantities, HMGB1 may induce macrophage pyroptosis and immunosuppression, thereby impairing the host's ability to eradicate microbial infections. A number of endogenous proteins have been shown to bind HMGB1 to modulate its extracellular functions. Here, we discuss an emerging possibility to develop therapeutic antibodies against harmless proteins that collude …

In the brain, compact clusters of neuron cell bodies, termed nuclei, are essential for maintaining parameters of host physiology within a narrow range optimal for health. Neurons residing in the brainstem dorsal motor nucleus (DMN) project in the vagus nerve to communicate with the lungs, liver, gastrointestinal tract, and other organs. Vagus nerve-mediated reflexes also control immune system responses to infection and injury by inhibiting the production of tumor necrosis factor (TNF) and other cytokines in the spleen, although the function of DMN neurons in regulating TNF release is not known. Here, optogenetics and functional mapping reveal cholinergic neurons in …

An Oxygen-Rich Atmosphere Or Systemic Fluoxetine Extend The Time To Respiratory Arrest In A Rat Model Of Obstructive Apnea, S. Mooney, R. Kollmar, R. Gurevich, J. Tromblee, A. Banerjee, K. Sundaram, J. B. Silverman, M. Stewart

Journal Articles

© 2019 Elsevier Inc. Audiogenic seizure-prone mice can be protected from seizure-associated death by exposure to an oxygen atmosphere or treatment with selective serotonergic reuptake inhibitors (SSRIs). We have shown previously in a rat model that epileptic seizure activity can spread through brainstem areas to cause sufficient laryngospasm for obstructive apnea and that the period of seizure-associated obstructive apnea can last long enough for respiratory arrest to occur. We hypothesized that both the oxygen-rich atmosphere and SSRIs function by prolonging the time to respiratory arrest, thus ensuring that seizure activity stops before the point of respiratory arrest to allow recovery …

Gut Microbiota-Derived Indole 3-Propionic Acid Protects Against Radiation Toxicity Via Retaining Acyl-Coa-Binding Protein, H. W. Xiao, M. Cui, Y. Li, J. L. Dong, S. Q. Zhang, C. C. Zhu, M. Jiang, T. Zhu, H. C. Wang, S. J. Fan, +1 Additional Author

Journal Articles

© 2020 The Author(s). Background: We have proved fecal microbiota transplantation (FMT) is an efficacious remedy to mitigate acute radiation syndrome (ARS); however, the mechanisms remain incompletely characterized. Here, we aimed to tease apart the gut microbiota-produced metabolites, underpin the therapeutic effects of FMT to radiation injuries, and elucidate the underlying molecular mechanisms. Results: FMT elevated the level of microbial-derived indole 3-propionic acid (IPA) in fecal pellets from irradiated mice. IPA replenishment via oral route attenuated hematopoietic system and gastrointestinal (GI) tract injuries intertwined with radiation exposure without precipitating tumor growth in male and female mice. Specifically, IPA-treated mice represented …

Targeting Inflammation Driven By Hmgb1, H. Yang, H. Wang, U. Andersson

Journal Articles

© Copyright © 2020 Yang, Wang and Andersson. High mobility group box 1 (HMGB1) is a highly conserved, nuclear protein present in all cell types. It is a multi-facet protein exerting functions both inside and outside of cells. Extracellular HMGB1 has been extensively studied for its prototypical alarmin functions activating innate immunity, after being actively released from cells or passively released upon cell death. TLR4 and RAGE operate as the main HMGB1 receptors. Disulfide HMGB1 activates the TLR4 complex by binding to MD-2. The binding site is separate from that of LPS and it is now feasible to specifically interrupt …

Monoclonal Antibodies Capable Of Binding Sars-Cov-2 Spike Protein Receptor Binding Motif Specifically Prevent Gm-Csf Induction., X. Qiang, S. Zhu, J. Li, P. Wang, K. J. Tracey, H. Wang

Journal Articles

A severe acute respiratory syndrome (SARS)-like coronavirus (SARS-CoV-2) has recently caused a pandemic COVID-19 disease that infected more than 25.6 million and killed 852,000 people worldwide. Like the SARS-CoV, SARS-CoV-2 also employs a receptor-binding motif (RBM) of its envelope spike protein for binding the host angiotensin-converting enzyme 2 (ACE2) to gain viral entry. Currently, extensive efforts are being made to produce vaccines against a surface fragment of a SARS-CoV-2, such as the spike protein, in order to boost protective antibody responses. It was previously unknown how spike protein-targeting antibodies would affect innate inflammatory responses to SARS-CoV-2 infections. Here we generated …
