In order to describe the prevalence of hypercholesterolemia and hypertriglyceridemia in a cohort of HIV-infected children and adolescents in Latin America and to determine associations with highly active antiretroviral therapy (HAART), we performed this cross-sectional analysis within the NICHD International Site Development Initiative pediatric cohort study. Eligible children had to be at least 2 years of age and be on HAART. Among the 477 eligible HIV-infected youth, 98 (20.5%) had hypercholesterolemia and 140 (29.4%) had hypertriglyceridemia. In multivariable analyses, children receiving protease inhibitor (PI)-containing HAART were at increased risk for hypercholesterolemia [adjusted odds ratio (AOR) = 2.7, 95% confidence interval (CI) 1.3-5.6] and hypertriglyceridemia (AOR = 3.5, 95% CI 1.9-6.4) compared with children receiving non-nucleoside reverse transcriptase inhibitor (NNRTI)-containing HAART. In conclusion, HIV-infected youth receiving PI-containing HAART in this Latin American cohort were at increased risk for hypercholesterolemia and hypertriglyceridemia compared with those receiving NNRTI-containing HAART.

Early diagnosis and appropriate therapy are essential for the best prognosis and quality of life in patients with primary immunodeficiency diseases (PIDDs). Experts from several Latin American countries have been meeting on a regular basis as part of an ongoing effort to improve the diagnosis and treatment of PIDD in this region. Three programmes are in development that will expand education and training and improve access to testing facilities throughout Latin America. These programmes are: an educational outreach programme (The L-Project); an immunology fellowship programme; and the establishment of a laboratory network to expand access to testing facilities. This report provides the status of these programmes based on the most recent discussions and describes the next steps toward full implementation of these programmes. (C) 2010 SEICAP.

Three Latin American oilseeds obtained from native fruits: nopal (tuna) (Opuntia ficus-indica), cherimoya (chirimoya) (Annona cherimola), and papaya, Chilean variety (Carica pubescens or C. candamarcensis) were studied for their fatty acid composition and bioactive compounds, such as tocols and phytosterols, looking for new sources of special oilseeds for this region. The results indicated that each species represents an interesting possibility. Nopal oilseed is a good source of linoleic acid (62%), with a good balance between SFA and MUFA (1: 1.3). Cherimoya oilseed presents quite a different composition, with 24% SFA, 43% MUFA and 33% PUFA. Palmitic and stearic acids (15% and 7.6%, respectively) are the main SFA. A good balance between oleic acid (42.7%) and linoleic acid (31%) was observed. Papaya oilseed is a highly MUFA oil (72% with 71% oleic acid), with a very interesting composition, according to the new nutritional and technological recommendations.With respect to bioactive compounds, the main tocol in these three oilseeds was gamma-tocopherol, with 136, 300 and 317 mg/kg for cherimoya, papaya and nopal oilseeds, respectively. According to the total tocol content, papaya oilseed presented the highest value with 384 mg/kg. The total amount and distribution of phytosterols was different, with values of 3092, 3554 and 5474 mg/kg for nopal, cherimoya and papaya oilseeds, respectively, with beta-sitosterol forming 47.6%, 65.0 % and 78.7% of the total phytosterol fractions, respectively. From the results obtained, Chilean papaya oilseed can be considered as a very promising new source of special plant oil for different applications, followed by cherimoya and nopal oilseeds.

Monte Carlo and molecular dynamics simulations and neutron scattering experiments are used to study the adsorption and diffusion of hydrogen and deuterium in zeolite Rho in the temperature range of 30-150 K. In the molecular simulations, quantum effects are incorporated via the Feynman-Hibbs variational approach. We suggest a new set of potential parameters for hydrogen, which can be used when Feynman-Hibbs variational approach is used for quantum corrections. The dynamic properties obtained from molecular dynamics simulations are in excellent agreement with the experimental results and show significant quantum effects on the transport at very low temperature. The molecular dynamics simulation results show that the quantum effect is very sensitive to pore dimensions and under suitable conditions can lead to a reverse kinetic molecular sieving with deuterium diffusing faster than hydrogen.

This thesis theoretically and critically examines the move towards people-centred approaches to development. It offers a critical examination of the work of Amartya Sen using theoretical resources emerging from Latin American traditions. Amartya Sen’s calls to understand Development as Freedom (1999) have significantly influenced mainstream development thinking and practice, constituting the clearest example of people-centred approaches to development today. Overcoming the limitations of previous state-centred notions of development articulated around ideas of economic growth, in Sen’s Capability Approach (CA) development is seen as a process of expanding the real freedoms that people enjoy. In this understanding, the agency of development shifts from the state to individuals and the analytic focus moves from economic growth to individual capabilities. In this manner, this framework is structured towards the central goal of empowerment, wherein the expansion of capabilities is seen both as the means and end of development. Since its inception, the widespread support for the CA has allowed for the expansion of ethical considerations within mainstream development thinking. Even while the remarkable advances offered by Sen’s work should be praised, this thesis argues that these have come with new limitations. These limitations stem from, what is termed here, a “Paradox of Empowerment” that effectively encloses Sen’s approach within Western notions of development. While Sen’s approach is poised to provide a theoretical framework that is built on the expansion of freedom and individual agency, there is little agency here to move beyond the ideas of development fundamentally linked to liberal democracies and market economies. This thesis engages with several critical traditions from Latin America, recovering their often undervalued insights for development thinking. Crucially, this engagement provides the critical framework to illustrate the aforementioned paradox and explore multiple dimensions of empowerment central for contemporary development thinking and practice. In this, the thesis engages Sen’s work with the Liberation Theology of Gustavo Gutierrez, with Paulo Freire’s Critical Pedagogy and with the contemporary discussions of ‘Buen Vivir’ associated with Indigenous philosophies of the Andean region. Throughout its chapters,it uncovers the conceptual baggage within the Paradox of Empowerment in Sen’s work and examines the ethical challenges and boundaries of this approach in relation to the collective dimension of development processes, the possibilities for structural transformation and concerns for sustainability. Progressively engaging the different dimensions of this paradox, this thesis advances the recovery of the transformative potential of the ideas of empowerment for development.
