Combating Antibiotic Resistance In The 21st Century, Kevin Krivanek, Brian Heilbronner, Brendan Rasor, Kelsey Lindsley, Andrew Roecker

Pharmacy and Wellness Review

Antibiotic resistance is one of the most significant challenges facing the medical community today. In response, the Centers for Disease Control and Prevention (CDC) created a list of the greatest antibiotic resistance threats, a number of which are gram-positive bacteria. The cell wall of these organisms has long been a favored target of antibiotic therapies, but the development of numerous resistance mechanisms has led to widespread resistance against nearly all major antibiotic compounds on the market. The medical community is faced with the task of developing better antibiotic compounds that preclude the spread of bacterial resistance and also increasing the …

Whooping Cough: A Pharmacist's Role In An Emerging Endemic, Haley Armstrong, Lydia Suchecki, Sarah Lipperman, Taylor Roberson, Andrew M. Roecker

Pharmacy and Wellness Review

Pertussis is an acute infectious disease caused by the organism Bordetella pertussis and characterized by a "whooping cough." Incidence of the disease had declined since the development of a vaccine, but is now increasing in reported cases. This increase has been attributed to both an increased awareness but also surmised to be related to a decrease in vaccinations. The pertussis vaccine is given in conjunction with tetanus and diphtheria vaccines to children before the age of 6 in five separate injections over the course of four to six years. A booster is now recommended for the older child and adults …

Fda Approves New Tuberculosis Drug: Bedaquiline (Sirturo®), Megan Ruffner, Kent Wilin, Charles Hay, Zachary Crawford, Andrew Roecker

Pharmacy and Wellness Review

Tuberculosis (TB), caused by the acid-fast bacilli (AFB) Mycobacterium tuberculosis, is an infectious disease that continues to greatly impact morbidity and mortality worldwide; in 2011 it caused 1.4 million deaths. Some strains of the bacteria have become resistant to current treatment regimens, resulting in multidrug-resistant (MOR) and extensively drugresistant (XOR) TB. The emergence of these resistant strains of bacteria calls for new treatment regimens that can quickly and effectively eradicate the organism. The U.S. Food and Drug Administration (FDA) recently approved Sirturo® (bedaquiline) with the indication of MDR pulmonary TB. Bedaquiline introduces a novel mechanism of action via the inhibition …

Fidaxomicin (Dificid®): New Antibiotic Approved For The Treatment Of Clostridium Difficile Infections, Sara M. Mcallister, Zachary Crawford, Joshua Ilenin, Ellen Hazelet, Andrew M. Roecker

Pharmacy and Wellness Review

Clostridium difficile is a gram-positive, spore forming bacteria normally transmitted by the fecal-oral route. Infection develops in patients with decreased normal gut flora and is typically associated with recent antibiotic use. Other risk factors include bowel surgery, compromised immune system function, extended hospital stays, and other underlying diseases. C. difficile bacteria produce two toxins, which cause increased intestinal fluid secretion and inflammation. Patients commonly present with diarrhea, abdominal discomfort, loss of appetite, and nausea. Current treatment guidelines are to discontinue antimicrobial agents and increase hydration. Less severe C. difficile associated diarrhea (CDAD) cases are treated with metronidazole 500 mg three …

Ecthyma Gangrenosum In An Immunocompromised Patient Without Detectable Bacteremia, Jonathan Miles, Alex Mari, Matthew Crabtree, Vinod Nambudiri, Jilian Sansbury

Dermatology

Ecthyma gangrenosum (EG) is typically pathognomonic of Pseudomonas aeruginosa bacteremia among immunocompromised patients, particularly with underlying malignancy. Recently, other pathogens and clinical histories have been implicated, challenging the classic picture of patients with EG. The cutaneous findings in patients follow a pattern of lesion progression from indurated pustules and hemorrhagic vesicles evolving to necrotic ulcers with central black eschar and surrounding erythema. While lesions typically occur on the perineum or lower extremities, their presence has also been described elsewhere. Herein, we describe a case of an immunocompromised man with chronic lymphocytic leukemia and multiple myeloma actively undergoing chemotherapy presenting with …

Optimizing Antibiotic Management Of Pediatric Acute Otitis Media In An Emergency Department, Alicia Daggett, Alaina N. Burns, Brian R. Lee, Nirav Shastri, Patricia Phillips, Rana E. El Feghaly

Posters

Problem

Children diagnosed with acute otitis media (AOM) at the Children's Mercy Hospital Kansas Emergency Department routinely get antibiotic prescriptions. There is rarely discussion with families about watchful waiting (defined as discussion of observation with parents and providing a safety-net antibiotic prescription that parents can ill if the patient is not improving or is worsening over the next 48 hours).

The aim of this quality improvement project is to increase watchful waiting for AOM at the CMK ED by 20% by March 2020, with an overall goal of decreasing antibiotic use for AOM.

Improving Pneumococcal Vaccination Rates In High Risk Patients Across Multiple Specialty Divisions, Rachel Moran, Julia G. Harris, Claire Olsen, Rana El Feghaly, Liset Olarte, Douglas Blowey, Luke A. Harris

Posters

Pediatric patients with deficient immune systems or certain chronic medical conditions have an increased risk of acquiring invasive pneumococcal disease.

The 23-valent pneumococcal (PPSV23) vaccine provides protection against 23 pneumococcal serotypes and is recommended for patients aged 2 years or older who are high-risk for invasive pneumococcal disease.

Unfortunately, many high-risk patients are not properly vaccinated due to lack of provider knowledge or understanding of accountability between primary care and specialty providers.

The goal of this project was to improve PPSV23 vaccination rates by 10-20% across multiple Children's Mercy Kansas City specialty divisions.

A Challenging Case Of Spontaneous Bacterial Empyema In A Cirrhotic Patient, Saad Emhmed Ali, Olalekan Akanbi, Macy Godman, Mohanad Soliman, Wesam M. Frandah, Karim Benrajab

Internal Medicine

Spontaneous Bacterial Empyema (SBEM) is distinguished as a primary infection of pre-existing hepatic hydrothorax in the absence of cardiopulmonary or pleural disease. It is an under-recognized complication of cirrhosis and is associated with high morbidity and mortality. The diagnosis requires chest imaging to rule out underlying pneumonia as an etiology; a diagnostic thoracentesis is crucial to make the diagnosis and should be obtained in any patient with pleural effusion and evidence of infection. Expeditious administration of antibiotics is essential to ameliorate the outcome. We present an interesting case of spontaneous bacterial empyema in a cirrhotic patient with hepatic hydrothorax.

Incidence And Prevalence Of Francisella Noatunensis Subsp. Orientalis (Fno) Pathogenic Infections In Feral Hawaiian Tilapia, Daquille Peppers

Biology Theses

Aquaculture has become a major food source for many countries and continues to grow each year. However, many of the fishes that are farmed are susceptible to pathogenic infections such as Francisellosis, a bacterial infection that contributes to disease and high mortality rate in many populations of farmed and wild fish around the world. In 1994, feral and farmed populations of tilapia (e.g. Oreochromis mossambicus) on Oahu, Hawaii were found to be infected with a novel Francisellosis strain, Francisella noatunensis subsp. orientalis (Fno). To prevent the spread of this pathogen, the Hawaii Department of Aquaculture (HDOA) initiated …

Elucidating Immune Signaling Of Influenza A Virus And Aspergillus Fumigatus Co-Infections Through Pioneered Model Development, Meagan Danyelle Rippee-Brooks

Graduate Theses/Dissertations

Bacterial co-infections with influenza A virus (IAV) are extremely serious and life-threatening. However, there exists limited understanding about the importance of fungal infections with IAV. Clinical case reports indicate that fungal co-infections do occur and suggest the IAV pandemic of 2009 had a propensity to predispose patients to secondary fungal infections more than previous IAV strains. IAV-fungal co-infections are marked by high mortality rates of 47 to 61% in previously healthy individuals between the ages of 20 and 60. Yet, the variables involved in this co-infection remain undetermined. I achieved effective recapitulation of this co-infection using a C57Bl/6 murine (mouse) …

Development Of Novel Zika And Anthrax Viral Nanoparticle Vaccines, Elizabeth Henderson

KGI Theses and Dissertations

Vaccines protect against numerous infectious diseases and prevent millions of deaths annually, but there are still many infectious diseases for which no licensed vaccine exists. Developing a new vaccine requires balancing safety and efficacy, and viral nanoparticle (VNP) vaccines possess both of these characteristics. The work herein demonstrates how tobacco mosaic virus (TMV) nanoparticles can serve as a platform to create candidate vaccines for Zika virus (ZIKV) and anthrax. In the first study, a ZIKV-specific epitope was genetically fused to TMV to create a safe and inexpensive vaccine that proved highly immunogenic in mice and led to the discovery of …

Transmissible Dermatological Diseases Affecting Syrian Refugees In Lebanon, Nisrine Kawa, Edith Hanna, Abdul Rahman Bizri

Journal of Refugee & Global Health

The Syrian war led many to seek shelter in Lebanon, creating a major refugee crisis. Displaced populations in crowded unequipped settlements are vulnerable to infectious diseases. The burden and incidence of various transmissible skin conditions affecting Syrian refugees in Lebanon and their impact on the Lebanese public health system were evaluated. Literature regarding these conditions among Syrian refugees in host countries, and epidemiological data from the Lebanese Ministry of Public Health Surveillance Unit and primary health-care network were reviewed. Lebanon has witnessed skin disorder outbreaks associated with the Refugee crisis, mainly leishmaniasis, scabies and lice infestations with little data about …

The Wet Bridge Transfer System: An Novel In Vitro Tool For Assessing Exogenous Surfactant As A Pulmonary Drug Delivery Vehicle, Brandon J. Baer

Western Research Forum

Background:

Due to its complex branching structure, direct drug delivery to the remote areas of the lung is a major challenge. Consequently, most therapies, such as those treating pulmonary infection and inflammation, must utilize large systemic dosing, with the potential for adverse side effects. A novel alternative strategy is to use exogenous surfactant, a material capable of distributing throughout the lung, as a pulmonary drug delivery vehicle.

Objective:

Utilize an in vitro transferring system to assess exogenous surfactant (BLES) as a pulmonary delivery vehicle for different therapeutics.

Methods:

An in vitro technique was developed to simultaneously study surfactant delivery and …

Group A Beta-Hemolytic Streptococcus Toxic Shock Syndrome Following Elective Termination Of Pregnancy: A Review Of Current Literature And Recommendations, Shannon Alexa, Jandie Schwartz

Rowan-Virtua Research Day

Group A Streptococcal Toxic Shock Syndrome (STSS) occurs as a subset of invasive Group A Streptococcal (GAS) infections accounting for roughly 10% of cases yearly. Of those, Puerpural Streptococcal infections occur only 0.5/10,000 live births but has a mortality rate of nearly 38% if management does not occur early^1,3,4. Despite the overall lower incidence of disease when compared to noninvasive forms, infection rates have started to rise over the last 10 years making it a necessity that practitioners be able to efficiently diagnose and treat infection. Presented here is the case of a 30 year old female who …
