Project Title: A Randomized, Placebo-Controlled Trial of HPV Vaccination to Reduce Cervical High-Grade Squamous Intraepithelial Lesions among HIV-Infected Women Participating in an HPV Test-and-Treat Program (COVENANT)
- To determine if HPV vaccination reduces the occurrence of cervical HSIL among HIV-infected women participating in an HPV test-and-treat strategy for cervical cancer prevention.
- To describe occurrence of cervical HSIL from week 52 to week 104.
- To examine the predictors of sustained absence of cervical HSIL through week 104 and clearance of HPV infections after cervical treatment, including: baseline types and quantity of HPV, presence of HSIL at baseline, cryotherapy vs. LEEP, CD4+ cell count, plasma HIV-1 RNA, ART use, age, sexual behavior, and vaccination use.
- To compare, between study arms, incident cervical vaccine type HPV infections and cervical cytology results.
- To describe prevalent and incident vulvar HSIL or cancer in this population.

- To evaluate the feasibility of an OC and OSD screening program within the high risk population.
- To determine the levels of PAH and acetaldehyde contained in food and drinking water, respectively.
- To assess the levels of PAH and acetaldehyde in human blood, urine, and mouthwash samples to determine their association with the presence of OSD.
- To investigate the association between OSD and genetic variants of PAH and alcohol metabolizing genes.
- To determine the nutritional status of participants by evaluating the vitamin B12 and folate levels in collected blood samples.
- To determine the levels of selenium in collected blood samples.
- To determine the level of nitrates/nitrites/nitrosamines in the water sources used by the community.
- To investigate the presence of antibodies to H. pylori and HPV in serum, and to assess current H. pylori status using the urease test.
- To determine the risk profile related to mild, moderate and severe dysplasia and resultant progression to OC, hence facilitating the placement of an early detection and screening policy for OC in the Eastern Cape Province.

Project Title: Patient’s Decisional Control Preferences in the Palliative Care Setting: A Multi-Center Survey
Aim: The overall purpose of this study is to collect preliminary data so as to compare the decisional control preference across the various countries and cultures.
- To describe the proportions of passive decision making for individual
- countries throughout the world.
- To compare the proportion of passive decision making in developed and developing countries.
- To determine the agreement between patients’ decisional control preferences and their self-reported actual decision-making experiences regarding cancer care
- To identify associations among patients’ decisional control preferences with their socio-demographic and clinical characteristics.
- To identify the factors that influence patient satisfaction with the decision-making process.
- To determine patients’ level of understanding of their illness and prognosis.
