Human immunodeficiency virus (HIV) is a retrovirus that attacks the immune system leading to people living with HIV (PLHIV) immunodeficient and more susceptible to other infections or diseases (UNAIDS, 2023b). This can lead to acquired immunodeficiency syndrome (AIDS) within 8-10 years of infection (UNAIDS, 2023b). HIV does not always present symptoms, making it hard for people to identify their HIV status without proper screening. The lack of awareness around a person’s status has led HIV to spread worldwide. In addition to the worldwide spread of HIV, there is no cure for the disease, however, antiretroviral therapy (ART) is mainly used …

INTRODUCTION: Little is known about the effects of universal test and treat (UTT) policies on HIV care outcomes among youth living with HIV (YLHIV). Moreover, there is a paucity of information regarding when YLHIV are most susceptible to disengagement from care under the newest treatment guidelines. The longitudinal HIV care continuum is an underutilized tool that can provide a holistic understanding of population-level HIV care trajectories and be used to compare treatment outcomes across groups. We aimed to explore effects of the UTT policy on longitudinal outcomes among South African YLHIV and identify temporally precise opportunities for re-engaging this priority …

Institute for Human Development

Genetic association studies have made significant contributions to our understanding of the etiology of neurodevelopmental disorders (NDDs). However, these studies rarely focused on the African continent. The NeuroDev Project aims to address this diversity gap through detailed phenotypic and genetic characterization of children with NDDs from Kenya and South Africa. We present results from NeuroDev’s first year of data collection, including phenotype data from 206 cases and clinical genetic analyses of 99 parent-child trios. Most cases met criteria for global developmental delay/intellectual disability (GDD/ID, 80.3%). Approximately half of the children with GDD/ID also met criteria for autism. Analysis of exome-sequencing …

Health Care In South Africa: An Overview Of Past And Current Challenges, Silas Westers Apr 2022

Health Care In South Africa: An Overview Of Past And Current Challenges, Silas Westers

Senior Honors Theses

The health care system in South Africa is a living remnant of apartheid. Divided and disjointed, the system is unable to cope with the significant challenges that exist in the public health of South Africa. Social issues such as poverty, inequality, and xenophobia influence how the health system operates. Health care workers face challenges such as communicable diseases, particularly HIV. Moving forward, the government plans to transition to a single payer nationalized health insurance (NHI) system. NHI will not solve all the problems the system faces, and the government must be diligent in rooting out corruption, incentivizing quality care, and …

Department of Pathology and Laboratory Medicine

Pneumococcal serotype 35B is an important non-conjugate vaccine (non-PCV) serotype. Its continued emergence, post-PCV7 in the USA, was associated with expansion of a pre-existing 35B clone (clonal complex [CC] 558) along with post-PCV13 emergence of a non-35B clone previously associated with PCV serotypes (CC156). This study describes lineages circulating among 35B isolates in South Africa before and after PCV introduction. We also compared 35B isolates belonging to a predominant 35B lineage in South Africa (GPSC5), with isolates belonging to the same lineage in other parts of the world. Serotype 35B isolates that caused invasive pneumococcal disease in South Africa in …

The Relationships Between Stress, Psychosocial Resources, And Mental Health And Adherence Outcomes Among Perinatally Hiv-Infected Adolescents In South Africa, Thabani Nyoni

Brown School Theses and Dissertations

Adolescents living with perinatally acquired HIV (APHs) in sub-Saharan Africa (SSA) constitute a significant population group that is experiencing poor HIV treatment outcomes (CIPHER Global Cohort Collaboration, 2018). Compared to younger children and older adults within the SSA sub-region, APHs experience poorer health outcomes, including retention in care, virologic treatment failure, and mortality rates (Anderson et al., 2019). Among countries in the SSA sub-region, South Africa has 360,000 adolescents living with HIV (ages 10-19), a disproportionate burden, accounting for 20% of the global adolescents living with HIV (UNAIDS, 2019a). The public health costs of suboptimal antiretroviral treatment (ART) adherence in …
