Intimin Likely Used To Cause Disease During Competition With Commensal Escherichia Coli, Dominique J. Richburg

Senior Honors Theses

The intimin gene in the Locus of Enterocyte Effacement (LEE) island of pathogenicity is the primary attachment mechanism in Citrobacter rodentium. Intimin is a bacterial adhesin (protein) that attaches to obtain a niche/nutrient and thrive within the intestine. Intimin was deleted within C. rodentium to study colonization and pathogenesis in the murine intestine. Additionally, C. rodentium is an attaching/effacing pathogen, and a useful murine model in understanding Enterohemorrhagic Escherichia coli (EHEC) infection in humans. E. coli and C. rodentium cause gastroenteritis in humans and mice, respectively. C. rodentium is a murine pathogen commonly used to model gastrointestinal disease because …

Targeting Interventions To Reduce Chlamydia-Related Disparities In Kalamazoo County Using Gis And Statistical Analysis, Claudio Owusu

Masters Theses

The annual incident rates of chlamydia continue to rise within Kalamazoo County despite an increase in public health campaign, particularly for persons between the ages of 15-24. This trend in incidence rates of chlamydia by age also shows strong disparities in race/ethnicity and gender at state and county levels. With the increasing burden on the cost of treatment of chlamydia, which is one of the many sexually transmitted infections, targeting high risk populations offers a means of reducing the cost and the spread of the infection. This has shaped attention of researchers and policy makers to the complexity of the …

Bioprosthetic Aortic Valve Endocarditis In Association With Enterococcus Durans, Luca Fallavollita, Lorena Di Gioacchino, Fabrizio Balestrini

The Texas Heart Institute Journal

Enterococci are common organisms associated with endocarditis, but infection by Enterococcus durans is very rare. To our knowledge, only 3 cases have been reported in the medical literature, and all 3 have involved native valves. Here we publish the first reported case (to our knowledge) of E. durans endocarditis in association with a bioprosthetic aortic valve. After the organism and its antibiotic susceptibility were identified, the 74-year-old male patient was treated successfully with teicoplanin and gentamicin, over a course of 6 weeks.

However, the relationship between lactate clearance and occurrence of death in severe septic patients is still unknown. Methods. This is a prospective cohort study that conducted in Ciptomangunkusumo Hospital, from March to May 2011. Patients were categorized into high lactate clearance group if there …

Perforated Small Intestine In A Patient With T-Cell Lymphoma; A Rare Cause Of Peritonitis, Petrisor Banu, Vlad D. Constantin, Florian Popa, Mihaela F. Nistor

Journal of Mind and Medical Sciences

The nontraumatic perforations of the small intestine are pathological entities with particular aspects in respect to diagnosis and treatment. These peculiarities derive from the nonspecific clinical expression of the peritonitis syndrome, and from the multitude of causes that might be the primary sources of the perforation: foreign bodies, inflammatory diseases, tumors, infectious diseases, etc. Accordingly, in most cases intestinal perforation is discovered only by laparotomy and the definitive diagnosis is available only after histopathologic examination. Small bowel malignancies are rare; among them, lymphomas rank third in frequency, being mostly B-cell non Hodgkin lymphomas. Only 10% of non-Hodgkin lymphomas are with …

A 22-Year-Old Man With Pleural Tuberculosis Associated Hydropneumothorax: Case Report And Literature Review., Lauren A Sharan, Thea Price, Md, Boyd Hehn, David Manoff, Md, Scott W. Cowan, Md

Department of Medicine Faculty Papers

A 22-year-old Asian male presented with fever, non-productive cough, right-sided pleuritic chest pain and was found to have a large right hydropneumothorax. A chest tube was placed. Pleural fluid analysis revealed a lymphocytic predominant exudate and he was subsequently started on four-drug daily anti-tuberculosis therapy (isoniazid, ethambutol, rifampin, pyrazinamide). Pleural biopsy revealed acid-fast bacilli. Given his persistent pleural effusion, he was given four doses of intrapleural tissue plasminogen activator (tPA) and dornase alpha (DNase) via his chest tube over a period of 6 days resulting in clinical and radiologic improvement. Pleural biopsy and pleural fluid culture specimens later revealed Mycobacterium …

Hcv-Induced Mir146a Controls Socs1/Stat3 And Cytokine Expression In Monocytes To Promote Regulatory T-Cell Development, Junping Ren, Rue S. Ying, Yong Q. Cheng, Ling Wang, Mohamed A. El Gazzar, Guang Y. Li, Shun B. Ning, Jonathon P. Moorman, Zhi Q. Yao

ETSU Faculty Works

Host innate and adaptive immune responses must be tightly regulated by an intricate balance between positive and negative signals to ensure their appropriate onset and termination while fighting pathogens and avoiding autoimmunity; persistent pathogens may usurp these regulatory machineries to dampen host immune responses for their persistence in vivo. Here, we demonstrate that miR146a is up‐regulated in monocytes from hepatitis C virus (HCV )‐infected individuals compared to control subjects. Interestingly, miR146a expression in monocytes without HCV infection increased, whereas its level in monocytes with HCV infection decreased, following Toll‐like receptor (TLR ) stimulation. This miR146a induction by HCV infection …

Tuberculosis is a major cause of morbidity and mortality in women of childbearing age (15-44 years). Despite increased tuberculosis risk during pregnancy, optimal clinical treatment remains unclear: safety, tolerability, and pharmacokinetic data for many tuberculosis drugs are lacking, and trials of promising new tuberculosis drugs exclude pregnant women. To advance inclusion of pregnant and postpartum women in tuberculosis drug trials, the US National Institutes of Health convened an international expert panel. Discussions generated consensus statements (>75% agreement among panelists) identifying high-priority research areas during pregnancy, including: (1) preventing progression of latent tuberculosis infection, especially in women coinfected with human …

Expression Of Complement And Toll-Like Receptor Pathway Genes Is Associated With Malaria Severity In Mali: A Pilot Case Control Study, Rafal S. Sobota, Antoine Dara, Jessica E. Manning, Amadou Niangaly

Dartmouth Scholarship

Background: The host response to infection by Plasmodium falciparum, the parasite most often responsible for severe malaria, ranges from asymptomatic parasitaemia to death. The clinical trajectory of malaria is influenced by host genetics and parasite load, but the factors determining why some infections produce uncomplicated malaria and some proceed to severe disease remain incompletely understood.

Methods: To identify molecular markers of severe falciparum malaria, human gene expression patterns were compared between children aged 6 months to 5 years with severe and uncomplicated malaria who were enrolled in a case–control study in Bandiagara, Mali. Microarrays were used to obtain expression …

The Association Between Vitamin A Status Or Supplementation And Hiv/Aids, Mikaela Kathleen Curtis

Food Science and Nutrition

The human immunodeficiency virus (HIV) has infected millions of people since the start of the epidemic in the early 1980s. HIV is the etiologic agent of the acquired immunodeficiency syndrome (AIDS), which has taken millions of lives. It is extremely difficult for particular populations to receive medication to treat HIV infection and prevent the progression of HIV to AIDS. Multiple studies have examined the effect of vitamin A on HIV infection, due to its immune stimulating effects. It is unclear whether an association exists between vitamin A and different aspects of HIV. This review examined the effect of vitamin A …

Micro-Rna And Mrna Profiles Associated With Ectopic Germinal Center Formation In Thymus Samples Of Patients With Autoimmune Myas, Manjistha Sengupta, Bi-Dar Wang, Norman H. Lee, Gary Cutter, Linda Louise Kusner, Henry J. Kaminski

GW Research Days 2016 - 2020

Myasthenia gravis (MG) is an autoimmune neuromuscular disorder caused by antibodies directed against proteins present at the post-synaptic surface of neuromuscular junction (NMJ). A characteristic pathology of patients with early onset MG is thymic hyperplasia with ectopic germinal centers (GC). However, mechanisms that trigger and maintain thymic hyperplasia are poorly characterized. Micro-RNAs (miRNA) are small, non-coding RNAs that are increasingly appreciated to be involved in the pathology of several autoimmune diseases. In order to determine the central mechanisms involved in the pathology, thymus samples from MG patients were assessed by histology and grouped based on appearance of GC compared to …

Use Of Concomitant Antibiotics During Treatment For Clostridium Difficile Infection (Cdi) In Pediatric Inpatients: An Observational Cohort Study., Vanessa W. Stevens, Cary Thurm, Elyse M. Schwab, Matthew P. Kronman, Jeffrey S. Gerber, Samir S. Shah, Jason G. Newland, Joshua Courter, Sarah Parker, Thomas V. Brogan, Adam L. Hersh

Manuscripts, Articles, Book Chapters and Other Papers

Concomitant antibiotic use during treatment for Clostridium difficile infection (CDI) increases the risk of recurrence. Across a network of children's hospitals, 46% of patients treated for CDI received concomitant antibiotics for a median of 7 days. Concomitant antibiotic use was more common among patients with malignancies, and solid organ or bone marrow transplant. Unnecessary concomitant antibiotic use in CDI patients is a potential target for pediatric antimicrobial stewardship.

Sepsis Management: An Evidence-Based Approach., Muhammad Akbar Baig, Hira Shahzad, Bushra Jamil, Erfan Hussain

Department of Medicine

The Surviving Sepsis Campaign (SSC) guidelines have outlined an early goal directed therapy (EGDT) which demonstrates a standardized approach to ensure prompt and effective management of sepsis. Having said that, there are barriers associated with the application of evidence-based practice, which often lead to an overall poorer adherence to guidelines. Considering the global burden of disease, data from low- to middle-income countries is scarce. Asia is the largest continent but most Asian countries do not have a well-developed healthcare system and compliance rates to resuscitation and management bundles are as low as 7.6% and 3.5%, respectively. Intensive care units are …

Manuscripts, Articles, Book Chapters and Other Papers

Many people living with HIV desire childbearing, but low cost safer conception methods (SCM) such as timed unprotected intercourse (TUI) and manual self-insemination (MSI) are rarely used. We examined awareness and attitudes towards SCM, and the correlates of these constructs among 400 HIV clients with fertility intentions in Uganda. Measures included awareness, self-efficacy, and motivation regarding SCM, as well as demographics, health management, partner and provider characteristics. Just over half knew that MSI (53%) and TUI (51%) reduced transmission risk during conception, and 15% knew of sperm washing and pre-exposure prophylaxis. In separate regression models for SCM awareness, motivation, and …

Conjugate Haemophilus Influenzae Type B Vaccines For Sickle Cell Disease., Slimane Allali, Martin Chalumeau, Odile Launay, Samir K. Ballas, Mariane De Montalembert

Cardeza Foundation for Hematologic Research

BACKGROUND: People affected with sickle cell disease are at high risk of infection from Haemophilus influenzae type b. Before the implementation of Haemophilus influenzae type b conjugate vaccination in high-income countries, this was responsible for a high mortality rate in children under five years of age. In African countries, where coverage of this vaccination is still extremely low, Haemophilus influenzae type b remains one of the most common cause of bacteraemias in children with sickle cell disease. The increased uptake of this conjugate vaccination may substantially improve the survival of children with sickle cell disease.

OBJECTIVES: The primary objective was …

Schuster, Ari Simenauer, Rangaraj Selvarangan, Rebecca A. Halpin, Xudong Lin, Nadia Fedorova, Timothy B. Stockwell, Tommy Tsan-Yuk Lam, James D. Chappell, Tina V. Hartert, Edward C. Holmes, Suman R. Das

Manuscripts, Articles, Book Chapters and Other Papers

In August 2014, an outbreak of enterovirus D68 (EV-D68) occurred in North America, causing severe respiratory disease in children. Due to a lack of complete genome sequence data, there is only a limited understanding of the molecular evolution and epidemiology of EV-D68 during this outbreak, and it is uncertain whether the differing clinical manifestations of EV-D68 infection are associated with specific viral lineages. We developed a high-throughput complete genome sequencing pipeline for EV-D68 that produced a total of 59 complete genomes from respiratory samples with a 95% success rate, including 57 genomes from Kansas City, MO, collected during the 2014 …

The Significance Of A Common Idiotype (1f7) On Antibodies Against Human Immune Deficiency Virus Type 1 And Hepatitis C Virus, Sybille Muller, Matthew S. Parsons, Heinz Kohler, Michael Grant

Microbiology, Immunology, and Molecular Genetics Faculty Publications

In this review, we trace the concept and potential functional role of regulatory idiotypes in the immune response to human immunodeficiency virus type 1 (HIV-1), simian immunodeficiency virus, and hepatitis C virus (HCV). A major idiotype involved in these viral infections is recognized and defined by a murine monoclonal antibody (1F7). Antibodies expressing the idiotype defined by 1F7 are dominant in HIV-1 infection and are also found on many broadly neutralizing antibodies against HIV-1. This regulatory idiotypic axis offers opportunities for exploitation in vaccine development for HIV-1, HCV, and other chronic viral infections.

Structural And Evolutionary Analyses Show Unique Stabilization Strategies In The Type Iv Pili Of Clostridium Difficile, Kurt H. Piepenbrink, Grace A. Maldarelli, Claudia F. Martinez De La Pena, Tanis C. Dingle, George L. Mulvey, Amanda Lee, Erik Von Rosenvinge, Glen D. Armstrong, Michael S. Donnenberg, Eric J. Sundberg

Food for Health: Publications

Type IV pili are produced by many pathogenic Gram-negative bacteria and are important for processes as diverse as twitching motility, biofilm formation, cellular adhesion and horizontal gene transfer. However, many Gram-positive species, including C. difficile, also produce Type IV pili. Here, we identify the major subunit of the Type IV pili of C. difficile, PilA1, and describe multiple three-dimensional structures of PilA1, demonstrating the diversity found in three strains of C. difficile. We also model the incorporation of both PilA1 and a minor pilin, PilJ, into the pilus fiber. Although PilA1 contains no cysteine residues, and therefore cannot form the …

Edwards, Vteu Rotavirus Vaccine Study Work Group

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND AND OBJECTIVES: Although both licensed rotavirus vaccines are safe and effective, it is often not possible to complete the schedule by using the same vaccine formulation. The goal of this study was to investigate the noninferiority of the immune responses to the 2 licensed rotavirus vaccines when administered as a mixed schedule compared with administering a single vaccine formulation alone.

METHODS: Randomized, multicenter, open-label study. Healthy infants (6-14 weeks of age) were randomized to receive rotavirus vaccines in 1 of 5 different schedules (2 using a single vaccine for all doses, and 3 using mixed schedules). The group receiving …

The Gras Sensor In Staphylococcus Aureus Mediates Resistance To Host Defense Peptides Differing In Mechanisms Of Action, Siyang Chaili, Ambrose L. L. Cheung, Arnold S. Bayer, Yan Q. Xiong, Alan Waring, Guido Memmi, Niles Donegan

Dartmouth Scholarship

Staphylococcus aureus uses the two-component regulatory system GraRS to sense and respond to host defense peptides (HDPs). However, the mechanistic impact of GraS or its extracellular sensing loop (EL) on HDP resistance is essentially unexplored. Strains with null mutations in the GraS holoprotein (ΔgraS) or its EL (ΔEL) were compared for mechanisms of resistance to HDPs of relevant immune sources: neutrophil α-defensin (human neutrophil peptide 1 [hNP-1]), cutaneous β-defensin (human β-defensin 2 [hBD-2]), or the platelet kinocidin congener RP-1. Actions studied by flow cytometry included energetics (ENR); membrane permeabilization (PRM); annexin V binding (ANX), and cell death protease activation (CDP). …

Tough Decisions For Premature Triplets., Ashley Hurst, Scott And Emily (Parents), Brooke D. Vergales, Alix Paget-Brown, Mark Mercurio, John Lantos

Manuscripts, Articles, Book Chapters and Other Papers

When infants are born at the borderline of viability, doctors and parents have to make tough decisions about whether to institute intensive care or provide only palliative care. Often, these decisions are made in moments of profound emotional turmoil, and parents receive different information from different health professionals. Communication can become garbled. It may be difficult to tell when and whether the patient's clinical condition has changed enough so that certain choices that had once been permissible become impermissible. In this "Ethics Rounds," we present a case of triplets born at the borderline of viability. We sought comments from the …
