Nurse initiated and managed anti-retroviral treatment: An ethical and legal analysis in South Africa.Ford, Pelisa 28 March 2014 (has links)
This research investigated the ethical and legal issues that impact on the urgent
implementation of Nurse Initiated and Managed Anti-Retroviral Treatment (NIMART) in
South Africa, which is part of the task-shifting strategy recommended by the World Health
Organization (WHO) to deal with the human resource shortage that has negatively impacted access to Anti-Retroviral Treatment (ART) in developing countries (WHO;2006). The objectives were to review and analyse the existing legal framework and provisions for
NIMART in South Africa; and to identify ethical issues and implications of NIMART within the current legal framework. It analysed the legal issues that impact on the implementation of NIMART within the public health service in South Africa, as well as the ethical basis and implications of NIMART on the practice of nurses in the scale-up of Anti-Retroviral Treatment in Primary Health Care (PHC). A comparative analysis was done with case studies of task-shifting in other developing countries and evidence-based recommendations for an enabling and long-term sustainable ethico-legal approach to task-shifting were established. The research concluded that despite the existing legal framework for NIMART in South Africa being firmly founded in the Constitution and further enabled by health policy, challenges exist in implementation of certain critical aspects of the enabling legislation relating to nurse training and accreditation required for full authorization to practice NIMART and that these technical challenges if not attended to could threaten the long-term sustainability of NIMART.

Utilizing cytotoxic lymphocytes for indirect shock-and-kill strategy in HIV-1 treatmentFurtado Milão, Joana FIlipa January 2021 (has links)
Despite the existence of a treatment, there is still not a cure for HIV-1 infection and there arearound 700 000 deaths per year from AIDS-related diseases. A major barrier for a cure is theestablishment of latent reservoirs that are impossible to distinguish from healthy cells and thuscan escape the immune system. One potential solution is called shock-and-kill strategy, whichaims to induce HIV-1 reactivation, exposing latently infected cells to the immune system andmaking them susceptible to cell death. In our lab, it was seen that when NK cells are stimulatedwith a pan-caspase inhibitor, they acquire the “shock” ability, but it is still unknown how. Inthis project, we observed that the supernatant from pan-caspase inhibitor-stimulated NK cellscan increase HIV-1 reactivation in two different latency models. Furthermore, the protein levelsof three HIV-1 suppressors were found to be increased in the same supernatant. For this reason,their effect in HIV-1 reactivation in latently infected cells was analysed. Although we did notobserve an increase in HIV-1 reactivation, the upregulation of these three proteins can be usefulin the clinical context. Since they are HIV-1 suppressors, their presence can prevent theinfection from spreading after latent cells are reactivated. Altogether, our results show that NKcells stimulated with a pan-caspase inhibitor are secreting a biological product that inducesHIV-1 reactivation. This indicates that there is a pathway in NK cells that can potentially beexploited in order for them to be able to induce HIV-1 reactivation.
