Tuberculosis Prevention: Current Strategies And Future Directions, Anca Vasiliu, Leonardo Martinez, Rishi K Gupta, Yohhei Hamada, Tara Ness, Alexander Kay, Maryline Bonnet, Martina Sester, Stefan H E Kaufmann, Christoph Lange, Anna M Mandalakas

Faculty, Staff and Students Publications

BACKGROUND: An estimated one fourth of the world's population is infected with Mycobacterium tuberculosis, and 5-10% of those infected develop tuberculosis in their lifetime. Preventing tuberculosis is one of the most underutilized but essential components of curtailing the tuberculosis epidemic. Moreover, current evidence illustrates that tuberculosis manifestations occur along a dynamic spectrum from infection to disease rather than a binary state as historically conceptualized. Elucidating determinants of transition between these states is crucial to decreasing the tuberculosis burden and reaching the END-TB Strategy goals as defined by the WHO. Vaccination, detection of infection, and provision of preventive treatment are key …

Evaluating Attitudes On Health-Seeking Behavior Among A Network Of People Who Inject Drugs, Ayako Shimada, Ashley Buchanan, Natallia Katenka, Benjamin Skov, Gabrielle Lemire, Stephen Kogut, Samuel Friedman

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

People who inject drugs (PWID) are often members of HIV/AIDS risk networks, where individuals engage in sexual and injection risk behavior. Engagement in HIV care is important for this population. Low socioeconomic status, stigmatization, and lack of access to medical care often complicate successful engagement in the HIV cascade of care for PWID. This study investigates how individual’s attitudes about how much control they have over HIV/AIDS risk in their life (i.e., locus of control and self-blame) affect health-seeking behavior in PWID participants and their community members. We applied causal inference methodology to PWID HIV risk networks ascertained from the …

Analyzing The Message Complexity, Signal Words, And Readability Of Medical Tourism Warning Messages, Alicia Mason, Sakshi Bhati

Faculty Submissions

Medical tourists are deemed to be a vulnerable patient population because they often have limited knowledge of the specialized health care treatment and services they seek. They are also frequently unfamiliar with the medical tourism physicians, providers, and facilitators with whom they interact. As a result, travel, biomedical, and procedural risks are often difficult to define and estimate. This analysis uses computer-automated technology to analyze the risk and warning messages distributed by government and private medical associations to medical tourists. Results show these messages are often complex and highly textual with little visual graphic elements. The messages frequently lack key …

Canine Parasites In Southern Nevada Urban Dog Parks: Paravec Study, Miklo Azrael A. Alcala

UNLV Theses, Dissertations, Professional Papers, and Capstones

While dogs are one of humans’ greatest companions, they also serve as hosts for a multitude of parasites. Urban dog parks serve as environments where the transmission of diseases is likely to occur. Exposure to infective agents, contained within the soil, intermediate hosts (e.g., rodents, rabbits), and feces, can directly affect the health of dogs and their owners. Other factors that can further influence canine health include age, previous diagnoses of parasites/diseases, and migration. Many dog owners visit dog parks to encourage socialization and exercise. Such activities are meant to improve health, but unawareness of microbiological organisms can lead to …

The Impact Of The Covid-19 Pandemic On Device-Associated Healthcare-Associated Infections In Nevada, Gabriela Bran

UNLV Theses, Dissertations, Professional Papers, and Capstones

Healthcare-associated infections or hospital-acquired infections (HAIs) have remained prevalent despite the growth of infection control programs in healthcare facilities and are a large cause of morbidity and mortality. Device-associated HAIs (DA-HAIs) make up a large portion of HAIs. The devices include central line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), and ventilator-associated events (VAEs). DA-HAIs became a large concern during the COVID-19 pandemic as many healthcare facilities became overwhelmed by the influx of COVID-19 cases, illuminating the importance of studies to examine these changes. Therefore, this study aimed to evaluate how DA-HAI rates have changed during and after the …
