Tanzania: Hiv/Aids, Francis Faasen

Global Public Health

Tanzania has a lot of issues going on in the community, but HIV/AIDS is the number one issue they are facing. Over 5% of their population has the HIV/Aids virus. There are many interventions that have been tried in Tanzania. In the last year there have been over 50,000 new cases of HIV/Aids in Tanzania. The goal is to main those numbers go down dramatically in the coming years. The two most common interventions are trying to educate this subject at a young age and provide condoms to the population. They tried giving condoms out to the people of Tanzania …

Chikungunya: India, Allison Harvey

Global Issues in Public Health

A communicable disease is an infectious disease, transmissible by direct contact with an affected individual or the individual’s discharges, or by indirect means. The more direct contact people have, the more disease spreads explaining why larger populations have more outbreaks of communicable diseases. India, in particular, has one of the biggest population sizes and makes them susceptible to those diseases. Many can be fatal. However, other diseases, such as chikungunya, are also dangerous viruses that put specific populations at risk for health problems if infected. With chikungunya symptoms such as fever or rashes may develop. Some symptoms such as joint …

Hiv/Aids: Nigeria, Lauren Tropinski

Global Issues in Public Health

Nigeria has one of the largest prevalence rates of HIV infections in Africa. HIV is a communicable disease that is transmitted by bodily fluids through unprotected sex, using contaminated needles, or mother to child. The most affected populations include heterosexuals who have unprotected sex, followed by sex workers, and men who have sex with men. People will experience three stages of HIV before the last stage referred to as AIDS. Rapid diagnostic tests are used to diagnose the disease. There is no cure for HIV/AIDS. However, people with HIV are given antiretrovirals to keep HIV at a low level throughout …

Type 1 Diabetes, Dan Bornstein

Global Issues in Public Health

The aim of this research was to increase the awareness of this disease and show the range of which it travels. Type 1 Diabetes, although not as common as Type 2 Diabetes, is a very serious disease present well around the world. Between the two forms, there are nearly 1.5 million people diagnosed with diabetes each year (American Diabetes Association, 2015). Northern European countries tend to have the highest prevalence of Type 1 diabetes. Younger children on average ages of 0-14 years, are most frequently struck with this disease (American Diabetes Association, 2015). With the given amount of symptoms that …

Dengue, Edward Ramos

Global Issues in Public Health

The dengue virus puts one third of the world’s population at risk. Humans carry the virus and mosquitoes pick it up and are able to spread to more people. As long as there are mosquitoes near you there is the possibility that you could become infected with the dengue virus. However, people living in tropical areas that are poverty stricken are much more likely to bit by these mosquitoes and developed dengue fever. Things like mosquito netting and proper plumbing help lower the amount of these mosquitoes from biting people. There are very few treatments for when a person gets …

El Salvador: Zika Virus, Annalia Fowler

Global Public Health

One of the current issues in El Salvador at the moment is the outbreak of Zika virus and the lack of understanding where it came from. Zika virus affects the population in many different ways. One of the most important ways that it affects the population is that it causes birth defects such as microcephaly and fetal death. In a country that already has a declining birth rate this could soon have grave effects on the population. As of right now El Salvador is working on an educational approach to stop the spread of the disease, as there is no …

Impact Of Chronic Sexual Abuse And Depression On Inflammation And Wound Healing In The Female Reproductive Tract Of Hiv-Uninfected And Hiv-Infected Women., Mimi Ghosh, Jason Daniels, Maria Pyra, Monika Juzumaite, Mariel Jais, Kerry Murphy, Tonya N Taylor, Seble Kassaye, Lorie Benning, Mardge Cohen, Kathleen Weber

Epidemiology Faculty Publications

Sexual violence is associated with increased risk of HIV acquisition/transmission in women. Forced sex can result in physical trauma to the reproductive tract as well as severe psychological distress. However, immuno-biological mechanisms linking sexual violence and HIV susceptibility are incompletely understood. Using the Women's Interagency HIV Study repository, a total of 77 women were selected to form 4 groups, stratified by HIV serostatus, in the following categories: 1) no sexual abuse history and low depressive symptom score (below clinically significant cut-off, scores

Epidemiology Faculty Publications

Background

Washington, DC, has one of the highest rates of HIV infection in the United States. Sexual intercourse is the leading mode of HIV transmission, and sexually transmitted infections (STIs) are a risk factor for HIV acquisition and transmission.

Methods

We evaluated the incidence and demographic factors associated with chlamydia, gonorrhea, and syphilis among HIV-infected persons enrolled at 13 DC Cohort sites from 2011 to 2015. Using Poisson regression, we assessed covariates of risk for incident STIs. We also examined HIV viral loads (VLs) at the time of STI diagnosis as a proxy for HIV transmission risk.

Surveillance Of South Dakota Mosquito Abundance, Infection Rate, And Insecticide Susceptibility, Geoffrey P. Vincent

Electronic Theses and Dissertations

The aim of this dissertation was to survey and evaluate the abundance, infection rate, and insecticide susceptibility of mosquito fauna present in South Dakota. Mosquito surveillance has been conducted across South Dakota to record and track potential West Nile virus (WNV) vectors from 2004 to 2017. The nuisance mosquito Aedes vexans was found to be the most abundant species overall in the state and most abundant in many of the regions. The WNV vector, Culex tarsalis, was found to be the second most abundant mosquito and the most abundant vector mosquito across the state. However, geospatial variation did exist between …

Cellular And Molecular Basis Of Equine Arteritis Virus Persistent Infection In The Stallion Reproductive Tract: Characterization Of Local Host-Pathogen Interactions Mediating Long-Term Viral Persistence, Mariano Carossino

Theses and Dissertations--Veterinary Science

Equine arteritis virus (EAV) has a global impact on the equine industry being the causative agent of equine viral arteritis (EVA), a reproductive, respiratory, and systemic disease of equids. A distinctive feature of EAV infection is that it establishes long-term persistent infection in the reproductive tract of stallions and is continuously shed in the semen (carrier state). Recent studies showed that long-term persistence is associated with a specific allele of the CXCL16 gene (CXCL16S). However, the cellular and molecular mechanisms underlying the establishment and maintenance of persistent infection are yet to be determined. The studies were undertaken herein …

Actual Vs. Perceived Hiv Testing Norms, And Personal Hiv Testing Uptake: A Cross-Sectional, Population-Based Study In Rural Uganda, Jessica M. Perkins, Viola N. Nyakato, Bernard Kakuhikire, Pamela K. 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 …

OHSU-PSU School of Public Health Faculty Publications and Presentations

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 …

This cross-sectional study recruited 200 HIV-infected patients from the Saint Francis Xavier Hospital, Assin Fosu, Ghana. Complete blood count, CD4 count, and urine dipstick analysis were measured for participants. The threshold values were determined as/

Comparative Genetic And Genomic Analysis Of The Novel Fusellovirus Sulfolobus Spindle-Shaped Virus 10, David Andrew Goodman, Kenneth M. Stedman

Biology Faculty Publications and Presentations

Viruses that infect thermophilic Archaea are unique in both their structure and genetic makeup. The lemon-shaped fuselloviruses—which infect members of the order Sulfolobales, growing optimally at 80 C and pH 3—are some of the most ubiquitous and best studied viruses of the thermoacidophilic Archaea. Nonetheless, much remains to be learned about these viruses. In order to investigate fusellovirus evolution, we have isolated and characterized a novel fusellovirus, Sulfolobus spindle-shaped virus 10 (formerly SSV-L1). Comparative genomic analyses highlight significant similarity with both SSV8 and SSV9, as well as conservation of promoter elements within the Fuselloviridae. SSV10 encodes five ORFs with no …

Of Rats And Men, Thomas S. Walsh

Capstones

This capstone is a data-driven investigation into New York City's rat problem. By using publicly available government data to map rat activity in NYC, I identified several socio-economic variables that correlate with rat populations at the community district, borough, and city-scale. I used these findings (mainly that rat problems are linked to lower incomes) as the basis of an investigation, which includes interviews with residents, experts, and city officials. Prof. Bobby Corrigan, urban rodentologist and formerly with the NYC Department of Health criticizes the city's efforts for the first time on the record.
