A Case Study Of The Political Determinant Of Health On The Public Health Crisis Of Malaria In Nigeria, Bisola M. Olumegbon

Electronic Theses and Dissertations

Abstract

Globally, there were about 229 million cases of malaria in 2022. The sub-Saharan African region accounted for 92% of the reported cases and 94% of deaths. Nigeria had the highest number of malaria cases and deaths, representing 27% of global cases. This scholarly project was a case study guided by the political determinants of health. Triangulation of data using thematic analysis was used to identify the political determinants of malaria in Nigeria and to understand how the concept of interaction contributes to the persistence of the disease. The analysis involved a deductive and inductive approach based on the literature …

Geospatial Modelling Of Lymphatic Filariasis And Malaria Co-Endemicity In Nigeria, Obiora A Eneanya, Lisa J Reimer, Peter U Fischer, Gary J Weil

2020-Current year OA Pubs

BACKGROUND: Lymphatic filariasis (LF) and malaria are important vector-borne diseases that are co-endemic throughout Nigeria. These infections are transmitted by the same mosquito vector species in Nigeria and their transmission is similarly influenced by climate and sociodemographic factors. The goal of this study was to assess the relationship between the geospatial distribution of both infections in Nigeria to better coordinate interventions.

METHODS: We used national survey data for malaria from the Demographic and Health Survey dataset and site-level LF mapping data from the Nigeria Lymphatic Filariasis Control Programme together with a suite of predictive climate and sociodemographic factors to build …

A Pathophysiological, Clinical, And Epidemiological View Of Malaria, Alyssa Watt

Senior Honors Theses

Malaria is a parasitic disease that is common among all ages in tropical and subtropical countries. Annually, there are an estimated 3.3 billion people in 97 countries at risk of contracting malaria. Malaria has been a major global health problem throughout history and is a leading cause of death and disease for many within tropical regions. In the past decade, efforts, such advances in medicine and insecticide techniques, have reduced the prevalence of malaria by 50% which suggests that the elimination of this disease is possible. With the prevalence of malaria and recent reduction, it is vital to aid in …

The Development Of Health System Resiliency: How Kenya's Experience With Malaria Impacted Its Reaction To The Covid-19 Pandemic, Zoe A. Ward

Baker Scholar Projects

Public health scholars have recently focused on health system resiliency to explain how previous experiences dealing with public health crises impact the healthcare sector, public behavior, and policy response to novel crises. However, it is unclear how resiliency develops. This study contributes by testing whether a health system’s experience with a health emergency and significant interventions impacts the response to a novel crisis. This research asks, “How has Kenya’s experience with malaria impacted its response to COVID-19?” Using the United States Agency for International Development (USAID) Malaria Indicator Survey (MIS), I develop a malaria adherence score to measure county-level compliance …

Activation Of The Plasmodium Egress Effector Subtilisin-Like Protease 1 Is Mediated By Plasmepsin X Destruction Of The Prodomain, Sumit Mukherjee, Armiyaw S. Nasamu, Kelly C. Rubiano, Daniel E. Goldberg

2020-Current year OA Pubs

Following each round of replication, daughter merozoites of the malaria parasite Plasmodium falciparum escape (egress) from the infected host red blood cell (RBC) by rupturing the parasitophorous vacuole membrane (PVM) and the RBC membrane (RBCM). A proteolytic cascade orchestrated by a parasite serine protease, subtilisin-like protease 1 (SUB1), regulates the membrane breakdown. SUB1 activation involves primary autoprocessing of the 82-kDa zymogen to a 54-kDa (p54) intermediate that remains bound to its inhibitory propiece (p31) postcleavage. A second processing step converts p54 to the terminal 47-kDa (p47) form of SUB1. Although the aspartic protease plasmepsin X (PM X) has been implicated …

Simple Polystyrene Microfluidic Device For Sensitive And Accurate Sers-Based Detection Of Infection By Malaria Parasites, Maria Joao Oliveira, Soraia Caetano, Ana Dalot, Filipe Sabino, Tomas Calmeiro, Elvira Fortunato, Rodrigo Martins, Eulalia Pereira, Miguel Prudencio, Hugh Byrne, Ricardo Franco, Hugo Aguas

Articles

Early and accurate detection of infection by pathogenic microorganisms, such as Plasmodium, the causative agent of malaria, is critical for clinical diagnosis and ultimately determines the patient’s outcome. We have combined a polystyrene-based microfluidic device with an immunoassay which utilises Surface-Enhanced Raman Spectroscopy (SERS) to detect malaria. The method can be easily translated to a point-of-care testing format and shows excellent sensitivity and specificity, when compared to the gold standard for laboratorial detection of Plasmodium infections. The device can be fabricated in less than 30 min by direct patterning on shrinkable polystyrene sheets of adaptable three-dimensional microfluidic chips. To validate …

Apolipoprotein E Genetic Variation, Atherogenic Index And Cardiovascular Disease Risk Assessment In An African Population: An Analysis Of Hiv And Malaria Patients In Ghana, Nicholas Ekow Thomford, Akwasi Anyanful, Richmond Owusu Ateko, Dee Blackhurst, Robert Peter Biney, Dennis Boadi, Samuel Badu Nyarko, Martins Ekor, George Boateng Kyei

2020-Current year OA Pubs

BACKGROUND: Apolipoprotein E is involved in lipid transport and clearance of lipoprotein through low-density lipoprotein receptors (LDLR). ApoE variation has been linked to cardiovascular disease (CVD) risk. There are 3 isoforms of ApoE which originate from two non-synonymous single nucleotide polymorphisms denoted as ε2, ε3 and ε4. The ε2 isoform is implicated in higher levels of atherogenic lipoprotein with the ε4 isoform causing LDLR downregulation. This leads to variable effects and differential CVD risk. Malaria and HIV are life-threatening diseases affecting several countries globally especially in sub-Saharan Africa. Parasite and viral activities have been implicated in lipid dysregulation leading to …

Impact Of Malaria Rapid Diagnostic Test On The Receipt Of Antimalarials Among Children Aged 6-59 Months In Nigeria From 2010 To 2021, Sandra Chibuzor Olisakwe

All ETDs from UAB

Background: Nigeria has the highest malaria burden globally, and antimalarials have been commonly used to treat malaria without parasitological confirmation. In 2012, Nigeria implemented RDTs to reduce use of antimalarials for those without malaria and to increase the use of artemisinin-combination therapies (ACTs) for malaria treatment. In this study, we examined trends in antimalarial receipt among children aged 6-59 months during a 12-year period of increasing RDT availability. Methods: We conducted a cross-sectional analysis using nationally representative Nigeria Malaria Indicator Survey (NMIS) data from 2010 (before RDT implementation), 2015, and 2021. NMIS surveys used histidine-rich protein 2 (HRP2)- based RDTs …
