The Neuroprotective Effects Of Targeted Temperature Management On Post-Cardiac Arrest Patients, Timothy Hovde

Physician Assistant Scholarly Project Papers

Novel methods of ensuring survival following cardiac arrest and resuscitation are of supreme importance to the medical community. Targeted temperature management (TTM) has become increasingly utilized pre-hospital, in emergency departments, and within intensive care units to increase the likelihood of survival to hospital discharge. TTM has further been used to attempt to improve neurological functioning. The efficacy and mechanism behind TTM remains poorly understood. In several patient populations it also remains unproven. The purpose of this study is to assess the physiological mechanism, survival, neurological recovery and methodology of TTM use and implementation.

Modernization and globalization are two of many factors to blame for lifestyle changes resulting in circadian disruption. The purpose of this literature review is to explore circadian misalignment with regards to its mechanism and impact on cardiometabolic health and to determine possible interventional measures. The primary focus is on lifestyle change, particularly …

Pre-Participation Physical Examination: Are Current Cardiovascular Recommendations Enough?, Steven Jacob Pietrusza

Physician Assistant Scholarly Project Papers

Inclusion of screening electrocardiograms (EKGs) during pre-participation physical examination has been a topic of debate for some time. There is unquestioned usefulness in the ability of a well-trained health care provider in using EKG to identify cardiac abnormalities. Further, there have been several contemporary EKG criteria published that increase specificity and sensitivity of detection of disease. However, these criteria do not account for athletes less than 14 years of age, and that demographic represents a large portion of patients seeking pre-participation screenings in the United States. The lack of research into pediatric cardiac remodeling secondary to activity, coupled with the …

Comparing The Effectiveness Of A Low Carbohydrate Diet And Metformin On Glycosylated Hemoglobin Reduction In Type Two Diabetes Mellitus, Ashley Schultz

Physician Assistant Scholarly Project Papers

In this study, a low carbohydrate diet and metformin pharmacotherapy were compared to determine their effect on HbA1c in the type two diabetic patient. Several high quality studies were examined along with each treatment's effect on mainly HbA1c, but also other parameters such as body weight, cholesterol, and fasting and post prandial blood glucose levels. The study showed that both the low carbohydrate diet and metformin pharmacotherapy were effective at lowering HbA1c in the type two diabetic patient. The low carbohydrate diet showed a 0.2% increase in HbA1c all the way to a 2.2% decrease in baseline HbA1c in the …

Associations Among Acne Vulgaris And Western Diet, Kate Meredith Suda

Physician Assistant Scholarly Project Papers

Acne vulgaris is one of the most common dermatologic conditions, especially among the adolescent population. The pathogenesis of acne is largely multifactorial, with heredity and hormones strongly contributing to one’s risk of developing the chronic inflammatory skin condition; it is related to excess sebum production by sebaceous glands, inflammation within comedones, and hyperproliferation of Propionibacterium acnes. High prevalence rates of acne in the adolescent population cannot be attributed to heredity alone, but by the influence of Western diet that overstimulates a key conductor of metabolism, the growth factor-sensitive kinase known as mTORC1. Many investigations show associations between acne and Western …

Mbabazi, H. Wesley Perkins, Alexander C. Tsai, Sv Subramanian, Nicholas A. Christakis, David Bangsberg

OHSU-PSU School of Public Health Faculty Publications and Presentations

HIV testing is an essential part of treatment and prevention. Using population-based data from 1664 adults across eight villages in rural Uganda, we assessed individuals’ perception of the norm for HIV testing uptake in their village and compared it to the actual uptake norm. In addition, we examined how perception of the norm was associated with personal testing while adjusting for other factors. Although the majority of people had been tested for HIV across all villages, slightly more than half of men and women erroneously thought that the majority in their village had never been tested. They underestimated the prevalence …

Background

Approaches to screening for active tuberculosis (TB) among people living with HIV are inadequate, leading to missed diagnoses and poor implementation of preventive therapy.

Methods

Consecutive HIV-infected adults hospitalized at Mulago Hospital (Kampala, Uganda) between June 2011 and July 2013 with a cough ≥ 2 weeks were enrolled. Patients underwent extensive evaluation for pulmonary TB. Concentrations of 43 cytokines/chemokines were measured at the same time point as C-reactive protein (CRP) in banked plasma samples using commercially-available multiplex kits. Advanced classification algorithms were used to rank cytokines/chemokines for their ability to identify TB, and to model the specificity of the …

Analysis Of Ocular Changes In A Cyp1b1-/- Mouse, Kylie Barto

Williams Honors College, Honors Research Projects

The goal of the research is to investigate the structural changes seen in Primary Congenital Glaucoma using a mouse model. Eye sections of a Cyp1b1-/- mouse were compared to eye sections of a healthy normal mouse (wild type, WT). Initial examination of the cornea, iris, and irodocorneal angle showed structural changes in Cyp1b1-/-. These changes were similar to those described in the literature using other animal models. This suggests that a mutation in Cyp1b1-/- in a mouse results in a phenotype similar to that seen in PCG human patients and this model could be used to investigate the pathophysiology of …

Innate Chemical Resistance Of Virginia Big-Eared Bats (Corynorhinus Townsendii Virginianus) To White-Nose Syndrome, Daniel S. Danford, Leah Shriver, Hazel A. Barton

Williams Honors College, Honors Research Projects

White-nose Syndrome (WNS) is an emergent epidemic disease of bats in North America. Caused by the novel fungal pathogen Pseudogymnoascus destructans, with a mortality rate of >75%, in the last decade WNS has led to the local extinction of numerous bat species. Despite this high mortality, one species, the Virginia big-eared bat (Corynorhinus townsendii virginianus) remains unaffected. Virginia big-eared bats (VBEs) are commonly found covered in a yellow, oily substance, with a pelage commensal population dominated by the yeast, Debaryomyces udenii. As D. udenii is an oleaginous yeast that produces yellow colonies, the fungus may be responsible …

Controlling Platelet Secretion To Modulate Hemostasis And Thrombosis, Smita Joshi

Theses and Dissertations--Molecular and Cellular Biochemistry

Upon vascular injury, activated blood platelets fuse their granules to the plasma membrane and release cargo to regulate the vascular microenvironment, a dynamic process central to platelet function in many critical processes including hemostasis, thrombosis, immunity, wound healing, angiogenesis etc. This granule- plasma membrane fusion is mediated by a family of membrane proteins- Soluble N-ethyl maleimide Attachment Receptor Proteins(SNAREs). SNAREs that reside on vesicle (v-SNAREs) /Vesicle-Associated Membrane Proteins(VAMPs) interact with target/t-SNAREs forming a trans-bilayer complex that facilitates granule fusion. Though many components of exocytic machinery are identified, it is still not clear how it could be manipulated to prevent …

Department of Nutrition and Health Sciences: Faculty Publications

Background: In the US, the percentage of adults with diagnosed diabetes are higher in members of racial and ethnic minority groups compared to non-Latino Whites. Understanding why such disparities exist has been less forthcoming.

Methods: Secondary data analysis was conducted using the National Health and Nutrition Examination Survey (NHANES) 1999-2000 cross-sectional data.

Results: H.pylori seropositivity was highest in Mexican Americans (43.7%), lowest in non- Hispanic Whites (18.1%). Diabetes was highest in non-Hispanic Blacks (5.9%); lowest in non-Hispanic whites (4.3%). H.pylori seropositivity was associated with greater likelihood of having type 2 diabetes (1.927, 95% CI 1.142, 3.257) compared to H.pylori negative …

Evaluation Of A Handheld Gluten Detection Device, Steve L. Taylor, Julie A. Nordlee, Shyamali Jayasena, Joseph L. Baumert

Department of Food Science and Technology: Faculty Publications

A portable, handheld gluten detection device, the Nima sensor, is now available for consumers wishing to determine if gluten is present in food. By United States regulation, gluten-free foods should contain < 20 ppm of gluten. Thirteen gluten-free foods (muffins, three different types of bread, three different types of pasta, puffed corn snack, ice cream, meatballs, vinegar and oil salad dressing, oatmeal, and dark chocolate) were prepared; each food was spiked on a weight-to-weight basis with gluten levels of 0, 5, 10, 20, 30, 40, and 100 ppm before processing or preparation. Unprocessed and processed foods were tested with the handheld gluten sensor and by two gluten-specific enzyme-linked immunosorbent assays (ELISAs) on the basis of the R5 and G12 monoclonal antibodies, respectively. The portable gluten detection device detected gluten in all food types at the 30-ppm addition level, failing to detect gluten in only 5 (6.4%) of 78 subsamples. At the 20-ppm addition level, the portable gluten detection device failed to detect gluten in one type of pasta but detected gluten residues in 63 (87.5%) of 72 other subsamples. The device was able to detect gluten at the 10-ppm addition level in 9 of the 13 food matrices (41 of 54 subsamples, 75.9%) but not in the three types of pasta and the puffed corn snack. The gluten-sensing device did not perform reliably at the 5-ppm addition level in 11 of 13 food matrices (exceptions: ice cream and muffins). In contrast, the ELISA methods were highly reliable at gluten addition levels of ≥ 10 ppm in all food matrices. The portable gluten detection device yielded a low percentage of false-positive results (4 of 111, 3.6%) in these food matrices. Thus, this handheld portable gluten sensor performed reliably in the detection of gluten in foods having ≥ 20 ppm of added gluten with only 18 (5.9%) of 306 failures, if results of the one type of pasta are excluded. The device worked with greater reliability as the gluten levels in the foods increased.
