Towards universal social protection: Latin American pathways and policy tools

This book reflects on the public policies, programmes and regulatory frameworks that are taking a rights-based approach to expanding social protection coverage and benefits in Latin America, with a view to achieving universal coverage. The book’s discussion of the policy tools and programmes pursued in the region aims to provide the reader with technical and programmatic insights for assembling and coordinating public policies within consistent and sustainable social protection systems. The combination of normative orientations and stock of technical knowledge, together with advances regarding the rights-based approach to social protection within a life cycle framework, afford the reader not only a tool box of specific social protection instruments, but also an in-depth examination of related political economy aspects.

Proteins of Leishmania (Viannia) shawi confer protection associated with Th1 immune response and memory generation

Background: Leishmania (Viannia) shawi parasite was first characterized in 1989. Recently the protective effects of soluble leishmanial antigen (SLA) from L. (V.) shawi promastigotes were demonstrated using BALB/c mice, the susceptibility model for this parasite. In order to identify protective fractions, SLA was fractionated by reverse phase HPLC and five antigenic fractions were obtained. Methods: F1 fraction was purified from L. (V.) shawi parasite extract by reverse phase HPLC. BALB/c mice were immunized once a week for two consecutive weeks by subcutaneous routes in the rump, using 25 mu g of F1. After 1 and 16 weeks of last immunization, groups were challenged in the footpad with L. (V.) shawi promastigotes. After 2 months, those same mice were sacrificed and parasite burden, cellular and humoral immune responses were evaluated. Results: The F1 fraction induced a high degree of protection associated with an increase in IFN-gamma, a decrease in IL-4, increased cell proliferation and activation of CD8(+)T lymphocytes. Long-term protection was acquired in F1-immunized mice, associated with increased CD4(+) central memory T lymphocytes and activation of both CD4+ and CD8(+) T cells. In addition, F1-immunized groups showed an increase in IgG2a levels. Conclusions: The inductor capability of antigens to generate memory lymphocytes that can proliferate and secrete beneficial cytokines upon infection could be an important factor in the development of vaccine candidates against American Tegumentary Leishmaniasis.

Structural and mechanical analysis for the optimization of PVD oxide coatings for protection against metal dusting

The evolution of the structure and properties of Cr/Cr oxide thin films deposited on HK40 steel substrates by reactive magnetron sputtering (RMS) was investigated and linked to their potential protective behavior against metal dusting. Deposition time, mode of oxygen feeding, and application of bias voltage were varied to assess their effect on the density, adhesion, and integrity of the films. All the films showed a very fine columnar microstructure and the presence of amorphous Cr oxide. Both, an increasing time and a constant oxygen flow during deposition led to the development of relatively low density films and mud-like cracking patterns. A graded oxygen flow resulted in films with fewer cracks, but a careful control of the oxygen flow is required to obtain films with a truly graded structure. The effect of the bias voltage was much more significant and beneficial. An increasing negative bias voltage resulted in the development of denser films with a transition to an almost crack-free structure and better adhesion. The amorphous oxide resulted in low values of hardness and Young's modulus. (C) 2012 Elsevier B.V. All rights reserved.

Definitions and outcome measures for bullous pemphigoid: recommendations by an international panel of experts

Our scientific knowledge of bullous pemphigoid (BP) has dramatically progressed in recent years. However, despite the availability of various therapeutic options for the treatment of inflammatory diseases, only a few multicenter controlled trials have helped to define effective therapies in BP. A major obstacle in sharing multicenter-based evidences for therapeutic efforts is the lack of generally accepted definitions for the clinical evaluation of patients with BP. Common terms and end points of BP are needed so that experts in the field can accurately measure and assess disease extent, activity, severity, and therapeutic response, and thus facilitate and advance clinical trials. These recommendations from the International Pemphigoid Committee represent 2 years of collaborative efforts to attain mutually acceptable common definitions for BP and proposes a disease extent score, the BP Disease Area Index. These items should assist in the development of consistent reporting of outcomes in future BP reports and studies.

Control of HIV-1 viremia and protection from AIDS are associated with HLA-Bw4 homozygosity

Certain HLA-B antigens have been associated with lack of progression to AIDS. HLA-B alleles can be divided into two mutually exclusive groups based on the expression of the molecular epitopes HLA-Bw4 and HLA-Bw6. Notably, in addition to its role in presenting viral peptides for immune recognition, the HLA-Bw4, but not HLA-Bw6, motif functions as a ligand for a natural killer cell inhibitory receptor (KIR). Here, we show that profound suppression of HIV-1 viremia is significantly associated with homozygosity for HLA-B alleles that share the HLA-Bw4 epitope. Furthermore, homozygosity for HLA-Bw4 alleles was also significantly associated with the ability to remain AIDS free and to maintain a normal CD4 T cell count in a second cohort of HIV-1-infected individuals with well defined dates of seroconversion. This association was independent of the presence of a mutation in CC chemokine receptor 5 (CCR5) associated with resistance to HIV-1 infection, and it was independent of the presence of HLA alleles that could potentially confound the results. We conclude that homozygosity for HLA-Bw4-bearing B alleles is associated with a significant advantage and that the HLA-Bw4 motif is important in AIDS pathogenesis.

The Lack of a Structured Universal Healthcare System in the United States: How This Affects the Lives of Millions of Americans and What Can Be Done About It

The purpose of this research is to explore on a deeper level the healthcare system of the United States, its background, and other factors that could provide possible solutions to simplify the fragmented healthcare system. The ultimate goal is the formation of concise ideas that could make the system, which prevents millions of Americans from obtaining adequate medical attention, substantially better. The paper will offer a better insight into the four different models of healthcare insurance found around the world in other developed countries with the purpose of establishing a comparison with that of the United States. The changes implemented by the Patient Protection and Affordable Care Act of 2010 are also analyzed to arrive at the conclusion of whether it has helped more American citizens get access to medical attention. Quality Improvement tools and thorough analysis of different methods from a financial, managerial, legal, and administrative perspective are used to provide valuable information that could aid in the implementation of modifications to the healthcare system of the United States in the near future.

Point of View: The importance of Leadership towards universal health coverage in Low Income Countries

Universal health coverage—defined as access to the full range of the most appropriate health care and technology for all people at the lowest possible price or with social health protection—was the goal of the 1978 Alma-Ata Conference on Primary Health Care in Kazakhstan. Many low-income (developing) countries are currently unable to reach this goal despite having articulated the same in their health-related documents. In this paper we argue that, over 30 years on, inadequate political and technical leadership has prevented the realization of universal health coverage in low-income countries.
