Filter by:1. Determine the "dose-response" relationship between a cash transfer amount and HIV viral suppression at 6 months 2. Identify the most effective cash transfer size to increase the proportion of people living with HIV infection (PLHIV) retained in care and with suppressed viral load (<1000 copies/ml) after 6 months. (This amount will be further evaluated in a cluster randomized trial in Phase 2).
Retrospective cohort of virologically suppressed HIV-infected patients who received the combination of Raltegravir plus Darunavir boosted with cobicistat or ritonavir, as dual therapy, because or toxicity or intolerance to nucleoside analogues
Introduction: It is well known that the infection caused by the Human Immunodeficiency Virus (HIV) is associated to a higher cardiovascular event risk. On the other hand, it is clear that the aerobic exercise training induces improvements in autonomic control and vascular function, through increases in vasodilator agents and blood vessels number. However, the investigators could not find previous works that studied the microvascular function in response to exercise training in HIV patients. Objectives: To study the impact of aerobic exercise training in endothelial function of HIV patients. In addition, the investigators will verify the association of the physical fitness to the nitric oxide bioavailability, angiogenesis and lipid profile in HIV patients. Methods: The study subjects will be composed by HIV patients, that will be randomly divided in two different groups: exercised and sedentary. The subjects will be tested before and after training in regards to endothelial function, nitric oxide bioavailability, physical fitness and lipid profile, through flowmetry, colorimetric essays, maximal cardiopulmonary exercise test, and biochemical tests; respectively. The exercise training will be performed in a treadmill for 12 weeks, 3 times a week, 40 minutes each section. Expected Results: The investigators expect to achieve markers that will help in understanding the interaction of HIV with several factors that contribute to an increased endothelial function after exercise training.
The goal of this research study is to evaluate the preliminary impact of a public-health-partnered tele-pharmacist model for pre-exposure prophylaxis (PrEP) delivery in a rural state ("TelePrEP"). In brief, PrEP involves daily use of a medication (i.e. Truvada) to prevent HIV infection among people at risk for infection due to sexual exposure or needle sharing. In this study, PrEP eligible rural and small urban-dwelling public health clients wil be enrolled in a prospective study to follow their progression through PrEP care following public health referrals. The study will involve a baseline survey to gather data on participant beliefs and attitudes about PrEP and a follow up telephone survey 30-40 days later to ascertain whether participants have engaged in PrEP. Medical records will be requested as a second method to determine whether participants have started PrEP and whether they are still using PrEP after six months. The hypotheses that PrEP initiation and retention are higher in regions with TelePrEP programs will be tested against control regions.
Randomized controlled trial of housing placement assistance for homeless persons with HIV
In natural HIV disease, a small fraction (1-2%) of infected individuals develops exceptionally high titres of HIV-1 neutralizing serum activity. Antibodies isolated from these individuals have been shown to be highly active against a broad range of different HIV strains and are therefore called broadly neutralizing antibodies (bNAbs). These antibodies are in fact able to prevent (S)HIV infection in animal models and therefore of great interest for the development of an HIV vaccine. Information of neutralizing antibodies in patients from Africa is still scarce and would be of great value in the development of adapted HIV vaccine strategies in these regions. This study aims to investigate African HIV-infected individuals, who have developed neutralizing antibodies using highly specialized laboratory methodologies.
Project Rise is a randomized controlled trial (RCT) of an innovative, culturally congruent treatment education (TE) intervention for African Americans with HIV that targets cultural and social issues contributing to health disparities.
Background: Love, Sex, and Choices (LSC) is a soap opera video series created to reduce HIV sex risk in women. Methods: LSC was compared to text messages in a randomized trial in 238 high-risk mostly Black young urban women. 117 received 12-weekly LSC videos, 121 received 12-weekly HIV prevention messages on smartphones. Changes in unprotected sex with high risk partners were compared by mixed models.
Cervical cancer is the leading cause of cancer death among women in Botswana. The burden of cervical cancer is largely related to the high prevalence of HIV in Botswana (22%), as HIV is known to be a significant risk factor for cervical cancer. Cervical cancer screening is life-saving and has been shown to reduce cervical cancer incidence in multiple settings. Yet, there is no consensus on appropriate screening algorithms for women living with HIV, across resource settings. Botswana is in a unique position, relative to its neighbors in Sub-Saharan Africa, in that there exists capacity for advanced screening modalities, including primary high risk human papilloma virus (hrHPV) testing and cytology-based screening. To address this issue, this study seeks to evaluate two-stage cervical cancer screening algorithms for women living with HIV in Botswana using hrHPV testing. The protocols include hrHPV testing followed by Pap Smear evaluation, VIA and colposcopy. These same participants will be invited back at one-year for cervical cancer screening using hrHPV testing (followed by triage testing) in order to inform guidelines on the frequency of HPV testing in women living with HIV. The evidence generated will be critical to guiding cervical cancer screening in HIV-infected women across resource settings.
The objective of the study is to evaluate the effectiveness of a HIV risk assessment tool to promote HIV testing and to reduce high risk sexual behaviors among men who have sex with men (MSM). It hypothesizes that the social media-based HIV risk assessment tool can increase 20% HIV testing proportion during the six months follow-up period.
