Educational Prevention Program Of Surgical Site Infections (Ssi), Carena Leung

Master's Projects and Capstones

Surgical site infections (SSI) cause negative health care effects to patients and hospitals. SSI is one of the most common types of healthcare-associated infections (HAI) accounting for 31% among hospitalized patients (Centers for Disease Control and Prevention [CDC], 2012). It is associated with prolonged length of stays (LOS), higher morbidity and mortality, and increased healthcare costs. The purpose of this quality improvement project is to decrease SSI rates by enhancing patient education and engagement in preoperative care and hygiene before surgery. In a metropolitan pediatric hospital, a microsystem analysis of the preoperative unit was conducted before generating the SSI Prevention …

Implementing A Pre-Exposure Prophylaxis Intervention For Safer Conception Among Hiv Serodiscordant Couples: Recommendations For Health Care Providers, Mari-Lynn Drainoni, Dea L. Biancarelli, Ashley A. Leech, Meg Sullivan, Angela R. Bazzi

Journal of Health Disparities Research and Practice

Couples in HIV serodiscordant relationships frequently desire children. Although partners who are virally suppressed pose almost no risk of transmitting HIV to their partners, partners who are inconsistently on therapy may transmit HIV to their partners when attempting to conceive. Pre-exposure prophylaxis (PrEP) is an available safer conception strategy for these couples but is not consistently offered. We sought to better understand barriers to PrEP implementation for couples seeking conception and patient perceptions on what providers could do to encourage use. We conducted in-depth, qualitative interviews with 11 participants representing six couples taking PrEP for safer conception in a safety-net …

Establishing Hematology And Serum Chemistry Reference Intervals For Wild Hawaiian Monk Seals (Neomonachus Schauinslandi), Angela C. Kaufman, Stacie J. Robinson, Dori L. Borjesson, Michelle Barbieri, Charles L. Littnan

United States Department of Commerce: Staff Publications

Hematology and serum chemistry reference intervals have been previously established for the endangered Hawaiian monk seal (Neomonachus schauinslandi) as an imperative measure for health assessments. Monitoring the health of the wild population depends upon reference intervals that are context specific; hence we developed reference intervals from fresh samples, as opposed to frozen, from wild monk seals. This study builds on the number of parameters from previous efforts by using samples collected between 2004 and 2015 from wild monk seals. Blood samples were analyzed by a single veterinary diagnostic laboratory within 24 hr of collection from apparently healthy, wild …

Development And Commissioning Of An Independent Peer Review System For A Small Animal Irradiator, Mary Peters

Dissertations and Theses (Open Access)

Dosimetry for small animal irradiators lacks the standardization of clinical radiotherapy practice, yet plays a central translational role in human trial design. The purpose of this work was to improve the dosimetric accuracy and consistency of animal studies by developing an independent peer review system to verify dose delivery from animal irradiators. This study focused on the development of a mouse phantom and characterization of the thermoluminescent dosimetry system for a commonly used small animal irradiator.

First, a mouse model and irradiation stand were designed with the purpose of being used in a mailable audit. Two mouse phantoms were machined …

Prevalence And Correlates Of Physical And Sexual Intimate Partner Violence Among Women Living With Hiv In Uganda, Cynthia R. Young, Angela Kaida, Jerome Kabakyenga, Winnie R. Muyindike, Nicholas Musinguzi, Jeffrey N. Martin, Peter W. Hunt, David Bangsberg, Jessica E. Haberer, Lynn T. Matthews

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Intimate partner violence (IPV) is a significant global health problem. Women who experience IPV have increased HIV incidence, reduced antiretroviral adherence, and a lower likelihood of viral load suppression. There is a lack of evidence regarding how to effectively identify and support women living with HIV (WLWH) experiencing IPV, including uncertainty whether universal or targeted screening is most appropriate for lower-resourced settings. We examined physical and sexual IPV prevalence and correlates among WLWH in Uganda to understand the burden of IPV and factors that could help identify women at risk.

Methods: We utilized data from women receiving …

OBJECTIVE: To develop standardized treatment regimens for chronic nonbacterial osteomyelitis (CNO), also known as chronic recurrent multifocal osteomyelitis (CRMO), to enable comparative effectiveness treatment studies.

METHODS: Virtual and face-to-face discussions and meetings were held within the CNO/CRMO subgroup of the Childhood Arthritis and Rheumatology Research Alliance (CARRA). A literature search was conducted, and CARRA membership was surveyed to evaluate available treatment data and identify current treatment practices. Nominal group technique was used to achieve consensus on treatment plans for CNO refractory to nonsteroidal antiinflammatory drug (NSAID) monotherapy and/or with active spinal lesions.

RESULTS: Three consensus treatment plans (CTPs) were developed …

Limiting Antibiotic Use In Acute Sinusitis: Partly A Matter Of Vocabulary?, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

In his issue introduction, the editor-in-chief of Journal of Patient-Centered Research and Reviews comments on an included article that describes the successful use of an electronic medical record best practice alert to reduce the rate of antibiotic prescription for acute sinusitis. Various methods previously tried to improve antibiotic stewardship in this illness are briefly reviewed. Borrowing on the model of acute bronchitis, it is suggested that a change in conveyed diagnostic vocabulary to “sinus cold” when describing acute sinusitis may help limit antibiotics for this predominantly viral infection.

Using Clinical Decision Support Within The Electronic Health Record To Reduce Incorrect Prescribing For Acute Sinusitis, Regina Ginzburg, Justin J. Conway, Eve Waltermaurer, Wendy Song, Samantha P. Jellinek-Cohen

Journal of Patient-Centered Research and Reviews

Purpose: Acute sinusitis has viral etiology in more than 90% of cases, but antibiotics are prescribed for more than 80% of adults in the United States. While applications of computer-assisted guidelines have been found effective in reducing inaccurate prescribing for acute respiratory infections, there is a paucity of research focused specifically on the utilization of electronic best practice alerts (BPA) in improving treatment for acute sinusitis.

Methods: This observational cohort study examined prescribing behavior for sinusitis at a single Federally Qualified Health Center 1 year prior and during the first year of implementation of a BPA in the electronic health …

Neurosyphilis: A Simulation Case For Emergency Medicine Residents., Chana Rich, Dimitrios Papanagnou, David Curley, Xiao Chi Zhang

Department of Emergency Medicine Faculty Papers

Neurosyphilis is a dangerous and increasingly more prevalent sexually transmitted infection of the central nervous system caused by the bacterium Treponemapallidum that can present during the advanced stages of the disease (tertiary syphilis). Health care providers must remain vigilant in screening for syphilis in patients with high-risk behaviors as a delay in diagnosis and treatment may lead to symptom progression and debilitating sequelae years later. To date, there have been no published simulation case studies on neurosyphilis. This simulation case, based on a real patient encounter, is written for emergency medicine residents to diagnose and manage a patient …

Transplant Critical Care: Is There A Need For Sub-Specialized Units? — A Perspective, Sujit Vijay Sakpal, Suresh Kumar Agarwal, Hector Saucedo-Crespo, Christopher Auvenshine, Robert N. Santella, Steven Donahue, Jeffery Steers

Department of Surgery

The critical care involved in solid-organ transplantation (SOT) is complex. Pre-, intra- and post-transplant care can significantly impact both – patients’ ability to undergo SOT and their peri-operative morbidity and mortality. Much of the care necessary for medical optimization of end-stage organ failure (ESOF) patients to qualify and then successfully undergo SOT, and the management of peri-operative and/or long-term complications thereafter occurs in an intensive care unit (ICU) setting. The current literature specific to critical care in abdominal SOT patients was reviewed. This paper provides a contemporary perspective on the potential multifactorial advantages of sub-specialized transplant critical care units in …

Bowel Preparation Quality Scales For Colonoscopy., David Kastenberg, Gerald Bertiger, Stuart Brogadir

Division of Gastroenterology and Hepatology Faculty Papers

Colorectal cancer (CRC) is the third most common cancer and second leading cause of cancer-related death in the United States. Colonoscopy is widely preferred for CRC screening and is the most commonly used method in the United States. Adequate bowel preparation is essential for successful colonoscopy CRC screening. However, up to one-quarter of colonoscopies are associated with inadequate bowel preparation, which may result in reduced polyp and adenoma detection rates, unsuccessful screens, and an increased likelihood of repeat procedure. In addition, standardized criteria and assessment scales for bowel preparation quality are lacking. While several bowel preparation quality scales are referred …

Background: Pakistan’s population is ethnically diverse with distinct ethnic groups inhabiting various parts of the country. Cancer statistics obtained from specific regions populated by distinct ethnic groups may vary considerably. There is no national cancer registry. To determine whether there are indeed significant statistical differences in cancer incidence and prevalence, data was recorded from different parts of Pakistan based on the ethnic composition of the population in those parts.
Methods: Ten papers (original articles) on cancer incidence and prevalence in Pakistan published in the last two decades were selected from PubMed and Google Scholar. Meta-analysis of findings of these studies …

The Utilization Of Laryngeal Mask Airways Vs. Endotracheal Tubes In Pediatrics With Upper Respiratory Tract Infection In Reducing Airway Complications, Ruby Foster

Nurse Anesthesia MSNA Student Capstones

According to Tait & Malviya, (2005) children typically experience six to eight upper respiratory infections (URIs) per year with ninety-five percent being viral in etiology (Tait & Malvia, 2005). URIs commonly occur in the pediatric population (Bernando-Ocampo, 2012). An issue surrounding the debate on whether a child with upper respiratory infection (URI) should proceed with surgery or cancel surgery is a debate that has been ongoing for several years (Tait el al. 2005). This review examines whether children who have an URI scheduled for surgery are at an increased risk for adverse respiratory complications when the laryngeal mask airway (LMA) …

Synovial sarcoma is a soft-tissue sarcoma. Its involvement of the spine is extremely rare. We report a 40 year old male who presented with shoulder pain and progressive weakness in all four limbs for six months with a visible, slowly growing bulge in his upper back. On examination he had quadriparesis and diffuse sensory deficit. MRI of the cervical spine showed a large soft tissue mass, iso to hypointense, extending into the neural canal, compressing the cord. The mass had a few internal areas of contrast enhancement with extension into the right paraspinal regions involving the vertebral bodies. Sub-periosteal spine …

Type 2 Bovine Viral Diarrhea Virus NPro Suppresses Type I Interferon Pathway Signaling In Bovine Cells And Augments Bovine Respiratory Syncytial Virus Replication, Abdulrahman Abdulaziz A. Alkheraif

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Bovine viral diarrhea virus (BVDV) and bovine respiratory syncytial virus (BRSV) infections contribute to the bovine respiratory disease complex (BRDC), which is a multi-factorial disorder involving co-infections of viruses and bacteria including mycoplasma. BRDC causes great economic losses to the United States feedlot industry. BVDV infection induces immunosuppression in infected animals. BVDV N^pro binds and degrades the transcription factor interferon regulatory factor-3 (IRF-3) and effectively blocks type I interferon (type I IFN) expression in host cells. BRSV nonstructural proteins, NS1 and NS2, block activation of IRF-3. In calves, concurrent infection with BVDV and BRSV resulted in more severe clinical …

Characterizing The Activity Of Antimicrobial Peptides Against The Pathogenic Bacterium Clostridium Difficile In An Anaerobic Environment, Adenrele Mojeed Oludiran

Chemistry & Biochemistry Theses & Dissertations

Clostridium difficile is an anaerobic Gram-positive pathogen with high treatment costs and mortality and very high antibiotic tolerance. Antimicrobial host-defense peptides (HDPs) produced naturally by animal immune systems are promising candidates to develop novel therapies for bacterial infection because they cause oxidative stress that damages multiple targets in bacterial cells, so it is difficult for bacteria to evolve resistance to these attacks.

Piscidins, fish-derived HDPs that can also form complexes with copper (Cu) to enhance their activities, are very active against multiple bacterial species in an aerobic environment. We examined their activity against C. difficile and other species in an …
