People Living With, Not Dying From Disease: Patient Empowerment Through Anti-Retroviral Therapy And Possibilities For Social Change, Xin Wei Ngiam

Independent Study Project (ISP) Collection

In South Africa today, it is estimated that there are 6.5 million people living with HIV/AIDS, at least half a million of whom require urgent treatment. On the continent of Africa as a whole the numbers are even more startling. Unfortunately, although the South African government has now committed itself to rolling out anti-retroviral therapy through the public healthcare system, progress has been slower than expected. Yet in numerous sites around South Africa, rollout centres have been established successfully, even in the most rural parts of the country. These programmes rely on existing community initiatives, community health workers and volunteers, …

Bacteriophage-Based Tests For The Detection Of Mycobacterium Tuberculosis In Clinical Specimens: A Systematic Review And Meta-Analysis, Shriprakash Kalantri, Madhukar Pai, Lisa Pascopella, Lee Riley, Arthur Reingold

Public and Community Health Sciences Faculty Publications

Background: Sputum microscopy, the most important conventional test for tuberculosis, is specific in settings with high burden of tuberculosis and low prevalence of non tuberculous mycobacteria. However, the test lacks sensitivity. Although bacteriophage-based tests for tuberculosis have shown promising results, their overall accuracy has not been systematically evaluated.

Methods: We did a systematic review and meta-analysis of published studies to evaluate the accuracy of phage-based tests for the direct detection of M. tuberculosis in clinical specimens. To identify studies, we searched Medline, EMBASE, Web of science and BIOSIS, and contacted authors, experts and test manufacturers. Thirteen studies, all based on …

Primary Prevention Healthcare Among Black American Men: Social Ecological Factors Predictive Of Prostate Cancer Early Detection Access, Virginia Diane Bush Agbonkhese Woods

Loma Linda University Electronic Theses, Dissertations & Projects

Access to healthcare requires individuals to have a place to go, a healthcare provider to see them, resources to obtain proper care, and the appropriate health services given in an appropriate timeframe. Non-Hispanic Black American men have the highest incidence rate of prostate cancer in the world, 180.6 per 100,000 (NCI, 2004). It is not clear as to why high rates persist, but higher death rates are associated with late detection. This mixed-methods ecological study was to investigate physician and Black male perceptions and practices regarding prostate cancer early detection with prostate specific antigen (PSA) blood test, and the digital …

Predictors Of Intention To Use Contraception, Given Alcohol Consumption, Among Women In Southeast Alaska, Donna Louise Hebbeler

Loma Linda University Electronic Theses, Dissertations & Projects

Fetal alcohol exposure is a serious public health problem and is 100% preventable. Traditionally, FASD prevention programs and research recommendations have targeted peri-conceptual or pregnant women. Another approach to the prevention of FASD involves preventing pregnancy in women who use alcohol. The purpose of this cross sectional study was to identify factors that predicted women’s intention to use contraception using the theory of planned behavior (TPB), to determine if predictors of the theoretical constructs varied in women depending on alcohol use, and to examine interactions between alcohol use and TPB constructs. Qualitative data was gathered to triangulate with the quantitative …
