Preclinical studies have shown that chronic alcohol abuse leads to alterations in the gastrointestinal microbiota that are associated with behavior changes, physiological alterations, and immunological effects. However, such studies have been limited in their ability to evaluate the direct effects of alcohol-associated dysbiosis. To address this, we developed a humanized alcohol-microbiota mouse model to systematically evaluate the immunological effects of chronic alcohol abuse mediated by intestinal dysbiosis. Germ-free mice were colonized with human fecal microbiota from individuals with high and low Alcohol Use Disorders Identification Test (AUDIT) scores and bred to produce human alcohol-associated microbiota or human control-microbiota F1 progenies. …

Characterization Of A Mycoplasma Pneumoniae Cards Toxin Mutant, Nikaash Pasnoori

Honors Scholar Theses

Mycoplasma pneumoniae is a high-burden pathogen which causes mild to significant infections of the respiratory system. According to the CDC, an estimated two million cases occur yearly in the United States alone, demonstrating the widespread effect of the pathogen. In addition to being the cause of respiratory infections, M. pneumoniae has also been implicated in exacerbating pre-existing asthma conditions. These morbidities make finding a vaccine candidate a vital part of easing the healthcare burden caused by the pathogen. The current mechanism of infection is unknown, but recent evidence points to the Community Acquired Respiratory Distress Syndrome (CARDS) toxin as being …

Community-Acquired Pneumonia In Adults: Diagnostic Reliability Of Physical Examination Techniques And Their Teaching In Academia, Amber Tordoff, Lauren A. Williams

Physician Assistant Capstones, 2016 to 2019

Background: Chest physical examination techniques are taught in academia, but their usefulness in the evaluation and diagnosis of patients in the clinical setting is controversial. Objective: To investigate the accuracy of physical examination techniques and their reliability in diagnosing community acquired pneumonia (CAP) and suggest a modified teaching approach to be used in academia. Design: Systematic Literature Review. Methods: Database search of PubMed and Google Scholar using the search terms “prediction of pneumonia in adults” and “prediction rule for pulmonary infiltrates.” Filters were implemented to include articles that only dealt with human subjects and were full text. Articles …

Mc-Ppea As A New And More Potent Inhibitor Of Clp-Induced Sepsis And Pulmonary Inflammation Than Fk866., Peixin Huang, Mark W Lee, Keivan Sadrerafi, Daniel P. Heruth, Li Q. Zhang, Dev Maulik, Shui Qing Ye

Our previous study indicated that overexpression of nicotinamide phosphoribosyltransferase (NAMPT) aggravated acute lung injury, while knockdown of NAMPT expression attenuated ventilator-induced lung injury. Recently, we found that meta-carborane-butyl-3-(3-pyridinyl)-2E-propenamide (MC-PPEA, MC4), in which the benzoylpiperidine moiety of FK866 has been replaced by a carborane, displayed a 100-fold increase in NAMPT inhibition over FK866. Here, we determined the effects of MC4 and FK866 on cecal ligation and puncture (CLP) surgery-induced sepsis in C57BL/6J mice. MC4 showed stronger inhibitory effects than FK866 on CLP-induced mortality, serum tumor necrosis factor α (TNFα) levels, pulmonary myeloperoxidase activity, alveolar injury, and interleukin 6 and interleukin1β messenger …

Intravenous Versus Oral Antibiotics For Postdischarge Treatment Of Complicated Pneumonia., Samir S. Shah, Rajendu Srivastava, Susan Wu, Jeffrey D. Colvin, Derek J. Williams, Shawn J.

BACKGROUND AND OBJECTIVES: Postdischarge treatment of complicated pneumonia includes antibiotics administered intravenously via a peripherally inserted central venous catheter (PICC) or orally. Antibiotics administered via PICC, although effective, may result in serious complications. We compared the effectiveness and treatment-related complications of postdischarge antibiotics delivered by these 2 routes.

METHODS: This multicenter retrospective cohort study included children ≥2 months andadministration, classified as PICC or oral. The primary outcome was treatment failure. Secondary outcomes included PICC complications, adverse drug reactions, other related revisits, and a composite of all 4 outcomes, termed "all related revisits."

RESULTS: Among 2123 children, 281 (13.2%) received antibiotics …

Executive Summary: The Management Of Community-Acquired Pneumonia In Infants And Children Older Than 3 Months Of Age: Clinical Practice Guidelines By The Pediatric Infectious Diseases Society And The Infectious Diseases Society Of America., John S.

Evidenced-based guidelines for management of infants and children with community-acquired pneumonia (CAP) were prepared by an expert panel comprising clinicians and investigators representing community pediatrics, public health, and the pediatric specialties of critical care, emergency medicine, hospital medicine, infectious diseases, pulmonology, and surgery. These guidelines are intended for use by primary care and subspecialty providers responsible for the management of otherwise healthy infants and children with CAP in both outpatient and inpatient settings. Site-of-care management, diagnosis, antimicrobial and adjunctive surgical therapy, and prevention are discussed. Areas that warrant future investigations are also highlighted.
