Comparison Of Maldi-Tof Ms And 16s Rrna Sequencing For Identification Of A Collection Of Clinical Isolates Of Nonntuberculous Mycobacteria In Kenya And Describing Their Antimicrobial Susceptibilities, David Enoch Kawalya

Master of Medicine in Clinical Pathology

Study background: non-tuberculous mycobacteria (NTM) are members of the genus Mycobacteria that are ubiquitous in the environment. They are increasingly documented to cause multi-drug resistant human and animal infections in immunocompromised as well as immunocompetent hosts and thus, they are a huge burden on public health resources. Diagnosis and treatment of these infections is particularly challenging due to their variable clinical presentation and the lack of easily accessible identification methods. MALDI-TOF MS is a proteomic method that has gained traction in the identification of microbial organisms in clinical practice due to its fast turn-around time, high resolution, and cost-effectiveness but …

Randomized Controlled Trial Comparing Post Operative Pain Outcome Between Suture And Tissue Glue Wound Apposition Post-Circumcision In The Pediatric Age Group, Happiness Obare

Master of Medicine in General Surgery

Introduction: Circumcision is one of the oldest and most common surgical procedures in the male population. Of the various circumcision techniques, sutures and tissue glue are utilized for wound closure in the free-hand techniques. Locally, sutures are routinely used for wound closure in the free-hand techniques. Whilst there are studies comparing the two wound apposition techniques using various outcomes, pain as a primary outcome comparing the two has been poorly researched. One hypothesis is that local ischemia at the suture site contributes to post-circumcision pain. It is against this background that we sought to explore differences in pain between these …

Tooth development anomalies can happen at many stages of cell development and are relatively common. These anomalies can be isolated findings however, they may also indicate minor or major associated syndromes and identification of these findings are essential to providing comprehensive care for patients. Dentin Dysplasia Type II is a rare autosomal dominant disease resulting from a disruption in the apposition stage of cell development. This disease affects the primary teeth and clinical manifestations can include bulbous crowns, cervical constriction, mild discoloration (amber color) and pulp obliteration. Permanent teeth tend to look typical but can demonstrate thistle-tube shaped pulps and/or …

Applying Mci-062, A Novel Pan-Ras Inhibitor, To Treat Kras-Mutant Lung Cancer., Richard Fu

Poster Presentations

Honors thesis poster presentation.

RAS, one of the most prevalent oncogenes, is mutated in 27% of human cancers. Gainof- function RAS mutations activate multiple downstream pathways, including the RASRAF- MEK-ERK and PI3K/AKT/mTOR pathways, which are critical in tumorigenesis and cancer cell proliferation. The RAS proteins KRAS, HRAS, and NRAS along with their downstream effectors are attractive targets for cancer therapy since they act as frequent drivers in lung, colorectal, and pancreatic cancers. However, RAS proteins have relatively smooth surfaces that lack traditional binding pockets, making inhibitors specific to RAS difficult to create. Recently, a novel small molecule pan-RAS inhibitor named …

Pain Assessment Policy Update And Nursing Education On Best Practices For Pain Assessment: A Quality Improvement Project, Jennifer Zhang

DNP Projects

Significance and Background: Chronic pain assessment should focus on patients' functional status, quality of life (QOL), and pain control. A tool to assess pain intensity and biopsychosocial impacts of pain for patients with chronic pain was needed in a Federally Qualified Health Center (FQHC). The Defense and Veterans Pain Rating Scale (DVPRS) incorporates a numeric rating scale with four functional questions on pain interference on ADLs. DVPRS design stimulates communication between patients and providers about their pain, its impact on function, and state of mind. Treatments are focused on making the pain tolerable and optimizing patient function while avoiding unwanted …

Intestinal Tuberculosis Presenting With Gastrointestinal Bleeding In Patient On Warfarin Therapy, Pascal Kuka, Joe Rakiro, Joseph Gatheru, Felix Riunga

Internal Medicine, East Africa

Background: Intestinal tuberculosis (ITB) constitutes less than 5% of overall cases of extrapulmonary disease and mostly affects the ileocecal region. The presentation and radiologic findings in enteric tuberculosis can mimic Crohn’s disease (CD).

Case Pre- sentation: We present a case report of an African woman who presented to a Kenyan hospital with lower gastrointestinal bleeding while on anticoagulation for valvular atrial fibrillation, and was diagnosed with intestinal tuberculosis after colonoscopy, biopsy, and positive staining for tuberculous bacilli.

Conclusion: Intestinal tuberculosis causing gastrointestinal bleeding is rare but should be suspected in patients living in TB endemic regions.

Resistance Training Effectiveness On Body Composition And Body Weight Outcomes In Individuals With Overweight And Obesity Across The Lifespan: A Systematic Review And Meta-Analysis, Pedro Lopez, Dennis R. Taaffe, Daniel A. Galvão, Robert U. Newton, Elisa R. Nonemacher, Victória M. Wendt, Renata N. Bassanesi, Douglas J. P. Turella, Anderson Rech

Research outputs 2022 to 2026

To systematically review and analyze the effects of resistance-based exercise programs on body composition, regional adiposity, and body weight in individuals with overweight/obesity across the lifespan. Using PRISMA guidelines, randomized controlled trials were searched in nine electronic databases up to December 2020. Meta-analyses were performed using random-effects model. One-hundred sixteen articles describing 114 trials (n = 4184 participants) were included. Interventions involving resistance training and caloric restriction were the most effective for reducing body fat percentage (ES = −3.8%, 95% CI: −4.7 to −2.9%, p < 0.001) and whole-body fat mass (ES = −5.3 kg, 95% CI: −7.2 to −3.5 kg, p < 0.001) compared with groups without intervention. Significant results were also observed following combined resistance and aerobic exercise (ES = −2.3% and −1.4 kg, p < 0.001) and resistance training alone (ES = −1.6% and −1.0 kg, p < 0.001) compared with no training controls. Resistance training alone was the most effective for increasing lean mass compared with no training controls (ES = 0.8 kg, 95% CI: 0.6 to 1.0 kg, p < 0.001), whereas lean mass was maintained following interventions involving resistance training and caloric restriction (ES = ~ − 0.3 kg, p = 0.550–0.727). Results were consistently observed across age and sex groups (p = 0.001–0.011). Reductions in regional adiposity and body weight measures were also observed following combined resistance and aerobic exercise and programs including caloric restriction (p < 0.001). In conclusion, this study provides evidence that resistance-based exercise programs are effective and should be considered within any multicomponent therapy program when caloric restriction is utilized in individuals with overweight or obesity.

Atr-Mediated Cd47 And Pd-L1 Upregulation Restricts Radiotherapy-Induced Immune Priming And Abscopal Responses In Colorectal Cancer, Cheng-En Hsieh, Cheng-En Hsieh

Dissertations and Theses (Open Access)

Radiotherapy of colorectal cancer (CRC) can prime adaptive immunity against tumor-associated antigen (TAA)-expressing CRC cells systemically. However, incidences of abscopal tumor remission are extremely rare, and the post-irradiation immune escape mechanisms in CRC remain elusive. We report that CRC cells utilize a common DNA repair signaling pathway — ATR/Chk1/STAT3 — to upregulate both CD47 and PD-L1 in response to radiotherapy, which through engagement of SIRPα and PD-1 suppresses the capacity of antigen-presenting cells to phagocytose them thereby preventing TAA cross-presentation and innate immune activation. This post-irradiation CD47 and PD-L1 upregulation can be observed across various human solid tumor cells. Concordantly, …

Clinical Pathways Leading To Antibiotic Initiation In Patients With Suspected Infection And Their Association With Delays And Mortality, X Han, C Lopez-Espina, P A. Verhoef, A Spicer, A Bhargava, L Schmalz, Matthew Sims, Alexandra Halalau, Nicholas Maddens, Aimee Espinosa

Conference Presentation Abstracts

Rationale: Delayed antibiotic therapy is associated with increased mortality in patients hospitalized with infection. The decision toinitiate therapy in patients with suspected infection is influenced by a variety of information, such as vital signs, and laboratoryresults. Identifying different patterns of events that lead to initiation is necessary to discover factors that could serve as targets forinterventions to expedite this process. We aimed to identify the most common sequences of events that precede antibioticordering and to quantify the time intervals between each event that contribute to antibiotic delays. Methods: This was aretrospective study of adult patients hospitalized at 4 community hospitals …

Community Health Worker Intervention To Improve Hba1c In Adult Diabetic Patients, Megan Wojtko

Doctor of Nursing Practice Projects

Type 2 Diabetes Mellitus (T2DM) is a disease that disproportionally impacts patients with multiple socioeconomic barriers that are often difficult to address during a primary care visit. Several provider and practice-level barriers also exist including time limitations within the visit and lack of trained staff to help with patient education and case management. Uncontrolled T2DM leads to poor health outcomes and increased healthcare costs. Community Health Workers (CHW) are trained lay persons that can successfully address the patient’s unmet needs and assist with the provider’s recommendations. The purpose of this project was to explore if a CHW led intervention focused …

Identification Of Ciprofloxacin Resistance Factors Via In Vivo Evolution Of Aeromonas Veronii In The Medicinal Leech, Lauren Daddi

Honors Scholar Theses

Infections from ciprofloxacin (Cp) resistant (Cp^R) Aeromonas veronii have been reported in increasing numbers among patients receiving leech therapy in recent years. Mutations in DNA gyrase, gyrA S83I, and DNA topoisomerase IV, parC E91K, along with acquisition of the qnrS2 gene located on the pAv42 plasmid, have been identified as genetic factors contributing to Cp^R in A. veronii. A strain of A. veronii harboring all known resistance factors was previously constructed and has a Cp minimum inhibitory concentration (MIC) of 3 µg/ml, which remains below the resistance threshold of 4 µg/ml and well below the high …
