The Development Of Environmental Dna (Edna) Sampling For Arbovirus Vector Surveillance In Southern Nevada, Katharine Brooke Major

UNLV Theses, Dissertations, Professional Papers, and Capstones

Vector-borne diseases account for 17% of all infectious diseases worldwide and are responsible for more than 700,000 deaths annually. Two-thirds of the global population are at risk of arthropod-borne RNA viruses (arboviruses), spread by mosquitoes, ticks, and sandflies, with these pathogens accounting for 37% of all emerging human diseases. Arboviruses are becoming increasingly important causes of neurological disease in the United States, presenting a significant public health problem. In the absence of available vaccines and efficacious treatment options, accurate, rapid, and cost-effective surveillance of arbovirus vectors is critical for monitoring species distribution and mitigating disease transmission risk. Currently, mosquito vector …

Modeling The Transmission Dynamics Of Tuberculosis In Humans, Farida Kisinda, Joshua A. Mwasunda, Mbwiga S. Aloni Apr 2024

Modeling The Transmission Dynamics Of Tuberculosis In Humans, Farida Kisinda, Joshua A. Mwasunda, Mbwiga S. Aloni

Tanzania Journal of Science

Tuberculosis (TB) is a major threat to human health particularly in most of developing countries. In this article, we formulate and analyze a deterministic model for the transmission dynamics of pulmonary and extra-pulmonary tuberculosis. The next generation method is employed to find the basic reproduction number which helps to determine whether TB clears or persists in the human population. Global stability of model equilibria is done through Lyapunov functions whereas the normalized forward sensitivity index method is adopted to determine parameters that drive tuberculosis. Analysis shows that both TB free and endemic equilibria exist. The TB free equilibrium is globally …

Modelling The Combined Use Of Long-Lasting Insecticidal Nets And Insecticides Zooprophylaxis Against The Resilience Of Anopheles Arabiensis For Effective Malaria Control, Watson Levens

Tanzania Journal of Science

Malaria is a significant public health concern, especially in tropical regions. It remains endemic in many areas where malaria mosquitoes are prevalent. This study investigates the viability of insecticide zooprophylaxis (IZ) in conjunction with Long Lasting Insecticidal Nets (LLINs) as a strategic approach to combat malaria transmission, particularly in regions dominated by zoophagic vectors. Through the presentation and analysis of a mathematical model that integrates IZ and LLINs for the control of Anopheles arabiensis (An. arabiensis), the research underscores IZ's role in reducing zoophagic vector populations and enhancing malaria control efforts. Notably, the study reveals that achieving comprehensive coverage of …


Dispelling The Malaria-Typhoid Co-Infection Myth In Nigeria. A Literature Review, Olawale Akinola Apr 2024

Dispelling The Malaria-Typhoid Co-Infection Myth In Nigeria. A Literature Review, Olawale Akinola

Dartmouth Library Staff Publications

Malaria and typhoid fever are public health concerns in Nigeria, with high prevalence rates. The perception of a widespread co-infection between these diseases may be misleading, due to limitations in diagnostic methods, particularly the Widal test for typhoid fever. This literature review examines the prevalence of malaria-typhoid co-infection in Nigeria and identifies factors contributing to misdiagnosis, including non-specific symptoms, limited diagnostic resources, and the diagnostic accuracy of tests employed. Additionally, the review discusses the implications of misdiagnosis, such as the overuse of broad-spectrum antibiotics leading to a rising incidence of antimicrobial resistance. Strategies to address this issue are explored, emphasizing …

International Journal of Aquatic Research and Education

The primary goal of this two-part project is to answer the rhetorical question of which strokes should be taught first, and which later (Langendorfer, 2013, Stallman, 2014a). As you have seen in Part One, we emphasize (as have many others) the need for a firm foundation before any stroke is introduced. When the learner is ready for propulsive motor competencies, there is no stroke which suits all as their first. In Part One we explored the “beginning strokes” all of which are candidates for any given learner’s first stroke. We also argued that after mastering their very first stroke the …

International Journal of Aquatic Research and Education

The aim of this article is to address the familiar question “Which swimming stroke should be taught first?” The discussion is usually focused on breaststroke versus crawl. Provoked by these naïve discussions of which stroke should be taught first (as if stroking equals swimming, which it emphatically does NOT), the question was answered metaphorically in an earlier article “No Stroke First – All Strokes First” (Stallman, 2008a). Here in Part I we identify and describe six strokes, all of which might be a candidate for any learners ‘very first’ stroke. We describe them as beginning strokes. Having identified and learned …

Tanzania Journal of Science

This study aimed to compare the dose distributions of three-dimensional conformal treatment planning using two and six radiation beams among paediatric patients receiving radiotherapy for Wilms tumour at Ocean Road Cancer Institute. CT scans of 53 patients were used to generate 106 treatment plans, 53 plans for two beams, and 53 plans for six beams. Planning target volumes and organs at risk parameters were compared between both plans using paired samples t-test.  A p-value < 0.05 was considered statistically significant. The findings showed that the D95% and Dmean of the target are better with six beams than with the two-beam plans (p ˂ 0.001). The conformity index and monitor unit are significantly better with two-beam plans than with six-beam plans (p ˂ 0.001). No volume of the contralateral kidney received more than 12 Gy for both two and six plans. There were no differences in Dmax for the spinal cord (p = 0.208), while Dmean was observed to be lower in two compared to six beams (p ˂ 0.001) for the liver. Six beam plans have good target coverage, while two beam plans have good conformity index and monitor unit. The observed doses to the organs at risk in both plans were lower than their normal tolerance.
