Análisis económico de las vacunas 10-valente y 13-valente contra neumococo: revisión sistemática

Introducción: Las vacunas clásicamente han representado un método económico y eficaz para el control y prevención de múltiples enfermedades infecciosas. En los últimos años se han introducido nuevas vacunas contra neumococo a precios elevados, y los diferentes análisis económicos a nivel mundial de estas vacunas no muestran tendencias. El objetivo de este trabajo era resumir la evidencia existente a través de los diferentes estudios económicos evaluando las dos vacunas de segunda generación contra neumococo en la población a riesgo. Metodología: En este trabajo se realizo una revisión sistemática de la literatura en 8 bases de datos localizadas en diferentes partes del mundo y también que tuvieran literatura gris. Los artículos fueron inicialmente evaluados acorde a su titulo y resumen, posteriormente los elegidos se analizaron en su totalidad. Resultados: Se encontraron 404 artículos, de los cuales 20 fueron incluidos en el análisis final. Se encontró que la mayoría de los estudios se realizaron en áreas donde la enfermedad tiene una carga baja, como es Norte América y Europa, mientras que en los lugares del mundo donde la carga es mas alta, se realizaron pocos estudios. De igual manera se observo que la mayoría de los estudios mostraron por los menos ser costo efectivos respecto a la no vacunación, y en su totalidad las dos vacunas de segunda generación mostraron costo efectividad respecto a la vacunación con PCV-7. Los resultados de los estudios son muy heterogéneos, hasta dentro del mismo país, señalando la necesidad de guías para la conducción de este tipo de estudios. De igual manera, la mayoría de los estudios fueron financiados por farmacéuticas, mientras en un numero muy reducido por entes gubernamentales. Conclusiones: La mayoría de los estudios económicos sobre las vacunas de segunda generación contra neumococo han sido realizados en países con un alto índice de desarrollo económico y patrocinados por farmacéuticas. Dado que la mayoría de la carga de la enfermedad se encuentran en regiones con un menor nivel de desarrollo económico se deberían realizar mas en estas zonas. De igual manera, al ser la vacunación un asunto de salud publica y con un importante impacto económico los gobiernos deberían estar mas involucrados en los mismos.

Convergencia de vías de señalización en un modelo de apoptosis

La sepsis es un evento inflamatorio generalizado del organismo inducido por un daño causado generalmente por un agente infeccioso. El patógeno más frecuentemente asociado con esta entidad es el Staphylococcus aureus, responsable de la inducción de apoptosis en células endoteliales debida a la producción de ceramida. Se ha descrito el efecto protector de la proteína C activada (PCA) en sepsis y su relación con la disminución de la apoptosis de las células endoteliales. En este trabajo se analizó la activación de las quinasas AKT, ASK1, SAPK/JNK y p38 en un modelo de apoptosis endotelial usando las técnicas de Western Blotting y ELISA. Las células endoteliales (EA.hy926), se trataron con C2-ceramida (130μM) en presencia de inhibidores químicos de cada una de estas quinasas y PCA. La supervivencia de las células en presencia de inhibidores químicos y PCA fue evaluada por medio de ensayos de activación de las caspasas 3, 7 y 9, que verificaban la muerte celular por apoptosis. Los resultados evidencian que la ceramida reduce la activación de AKT y aumenta la activación de las quinasas ASK, SAPK/JNK y p38, en tanto que PCA ejerce el efecto contrario. Adicionalmente se encontró que la tiorredoxina incrementa la activación/fosforilación de AKT, mientras que la quinasa p38 induce la defosforilación de AKT.

Los clusters como mecanismo para la generación de economías a escala en el sector de medicamentos de alto costo en Colombia

La presente investigación tiene por objeto considerar los cluster en la industria farmacéutica Colombiana, como un mecanismo para la disminución de los sobrecostos de los medicamentos, que han impactado de forma importante, entre otras causas, al sistema de salud, con unos recobros (por concepto de medicamentos No POS) que superan el billón de pesos, situación que dada la crisis que enfrenta al respecto, el Estado Colombiano, ha propuesto una quinta reforma que cursa actualmente en el Congreso de la República. Se trata de una investigación cualitativa tipo estudio de caso, en la que se presenta el modelo Colombiano de Salud y las cifras de recobros de las Empresas Prestadoras de Servicios de Salud (EPS), cantidad que representó el 0.4% del PIB (Producto Interno Bruto) en el 2009. Para tal fin se analizará el comportamiento de los recobros durante el año 2012, en cuarenta y una (41) EPS reconocidas del sector. Subsecuentemente se estudian las diferentes estrategias para la generación de economías de escala y dentro de ellas, los clusters como un posible modelo a seguir hacia la disminución de estos costos en salud, se analizan sus componentes y su posible constitución dentro del entorno Colombiano. Al final del estudio se establece como conclusión, que existen suficiente evidencia para apoyar la implementación de un cluster farmacéutico dentro del territorio Colombiano.

Entre la gobernanza social e institucional: Una mirada al fenómeno de la trata de personas en Colombia en el período entre 2000 y 2012

La presente monografía tiene por objetivo identificar la influencia de las acciones emprendidas por la sociedad civil y las organizaciones internacionales frente a la problemática de la trata de personas en Colombia, durante el período comprendido entre los años 2000 y 2012. En este sentido, la investigación constituye un esfuerzo por develar las transformaciones en las narrativas institucionales que han posibilitado el reconocimiento de los elementos de prevención y centralidad de las víctimas, como ejes articuladores del discurso gubernamental frente a la trata de personas. Para ello, se hace uso de la teoría de la gobernanza global enmarcada en el enfoque constructivista de las Relaciones Internacionales, en tanto permite establecer una relación entre las acciones de los diferentes actores y el impacto de estas en la construcción de estrategias nacionales para hacer frente a problemáticas que, como la trata de personas, se encuentran en estrecha relación con el mundo globalizado.

NANA: Novel assessment of nutrition and ageing

Purpose NANA is a 3-year project using sensitively-designed technology to improve data collection and integrate information on nutrition, physical and cognitive function and mental health to identify individuals at risk of under-nourishment and improve targeting of interventions. This research will also improve our understanding of the interactions between these factors, in order to better medical treatment and social provision. The toolkit has potential for commercial development for additional segments of the population. Method This is a multi-disciplinary program involving psychology, nutrition, engineering and software engineering. The first phase is a user needs analysis and will involve consulting with a broad cross-section of older people, caregivers, and health professionals, to establish what technical approaches would be useful and acceptable. The second phase focuses on the development of an integrated measurement toolkit. There are three inter-related subsections: (i) an iterative program to develop the assessment technology, (ii) techniques for dietary assessment in older people, and (iii) a parallel investigation of measures of cognition and mental health in older people. It includes a full validation of the assessment toolkit and will comprise a comparison of the new, integrated assessment with traditional 'pen and paper' methods with volunteers having the equipment installed in their homes.

The neuropsychology of male adults with High-Functioning Autism or Asperger Syndrome

Autism Spectrum Disorder (ASD) is diagnosed on the basis of behavioral symptoms, but cognitive abilities may also be useful in characterizing individuals with ASD. One hundred seventy-eight high-functioning male adults, half with ASD and half without, completed tasks assessing IQ, a broad range of cognitive skills, and autistic and comorbid symptomatology. The aims of the study were, first, to determine whether significant differences existed between cases and controls on cognitive tasks, and whether cognitive profiles, derived using a multivariate classification method with data from multiple cognitive tasks, could distinguish between the two groups. Second, to establish whether cognitive skill level was correlated with degree of autistic symptom severity, and third, whether cognitive skill level was correlated with degree of comorbid psychopathology. Fourth, cognitive characteristics of individuals with Asperger Syndrome (AS) and high-functioning autism (HFA) were compared. After controlling for IQ, ASD and control groups scored significantly differently on tasks of social cognition, motor performance, and executive function (P's < 0.05). To investigate cognitive profiles, 12 variables were entered into a support vector machine (SVM), which achieved good classification accuracy (81%) at a level significantly better than chance (P < 0.0001). After correcting for multiple correlations, there were no significant associations between cognitive performance and severity of either autistic or comorbid symptomatology. There were no significant differences between AS and HFA groups on the cognitive tasks. Cognitive classification models could be a useful aid to the diagnostic process when used in conjunction with other data sources-including clinical history.

Liquidity effects and FFA returns in the international shipping derivatives market

The study examines the impact of liquidity risk on freight derivatives returns. The Amihud liquidity ratio and bid–ask spreads are utilized to assess the existence of liquidity risk in the freight derivatives market. Other macroeconomic variables are used to control for market risk. Results indicate that liquidity risk is priced and both liquidity measures have a significant role in determining freight derivatives returns. Consistent with expectations, both liquidity measures are found to have positive and significant effects on the returns of freight derivatives. The results have important implications for modeling freight derivatives, and consequently, for trading and risk management purposes.

Segmenting the Italian coffee market: marketing opportunities for economic agents working along the international coffee chain

Globalization, either directly or indirectly (e.g. through structural adjustment reforms), has called for profound changes in the previously existing institutional order. Some changes adversely impacted the production and market environment of many coffee producers in developing countries resulting in more risky and less remunerative coffee transactions. This paper focuses on customization of a tropical commodity, fair-trade coffee, as an approach to mitigating the effects of worsened market conditions for small-scale coffee producers in less developed countries. fair-trade labeling is viewed as a form of “de-commodification” of coffee through product differentiation on ethical grounds. This is significant not only as a solution to the market failure caused by pervasive information asymmetries along the supply chain, but also as a means of revitalizing the agricultural-commodity-based trade of less developed countries (LDCs) that has been languishing under globalization. More specifically, fair-trade is an example of how the same strategy adopted by developed countries’ producers/ processors (i.e. the sequence product differentiation - institutional certification - advertisement) can be used by LDC producers to increase the reputation content of their outputs by transforming them from mere commodities into “decommodified” (i.e. customized and more reputed) goods. The resulting segmentation of the world coffee market makes possible to meet the demand by consumers with preference for this “(ethically) customized” coffee and to transfer a share of the accruing economic rents backward to the Fair-trade coffee producers in LDCs. It should however be stressed that this outcome cannot be taken for granted since investments are needed to promote the required institutional innovations. In Italy FTC is a niche market with very few private brands selling this product. However, an increase of FTC market share could be a big commercial opportunity for farmers in LDCs and other economic agents involved along the international coffee chain. Hence, this research explores consumers’ knowledge of labels promoting quality products, consumption coffee habits, brand loyalty, willingness to pay and market segmentation according to the heterogeneity of preferences for coffee products. The latter was assessed developing a D-efficient design where stimuli refinement was tested during two focus groups.

The Snake Venom Peptide Bj-PRO-7a Is a M1 Muscarinic Acetylcholine Receptor Agonist

Proline-rich peptides from Bothrops jararaca venom (Bj-PRO) were characterized based on the capability to inhibit the somatic angiotensin-converting enzyme. The pharmacological action of these peptides resulted in the development of Captopril, one of the best examples of a target-driven drug discovery for treatment of hypertension. However, biochemical and biological properties of Bj-PROs were not completely elucidated yet, and many recent studies have suggested that their activity relies on angiotensin-converting enzyme-independent mechanisms. Here, we show that Bj-PRO-7a (International Society for Advancement of Cytometry

Factors associated with increased prevalence of human papillomavirus infection in a cohort of HIV-Infected Brazilian women

Objectives: Human papillomavirus (HPV) infection is a major risk factor for cervical disease. Using baseline data from the HIV-infected cohort of Evandro Chagas Clinical Research Institute at Fiocruz, Rio de Janeiro, Brazil, factors associated with an increased prevalence of HPV were assessed. Methods: Samples from 634 HIV-infected women were tested for the presence of HPV infection using hybrid capture 11 and polymerase chain reaction. Prevalence ratios (PR) were estimated using Poisson regression analysis with robust variance. Results: The overall prevalence of HPV infection was 48%, of which 94% were infected with a high-risk HPV. In multivariate analysis, factors independently associated with infection with high-risk HPV type were: younger age (<30 years of age; PR 1.5, 95% confidence interval (CI) 1.1-2.1), current or prior drug use (PR 1.3, 95% CI 1.0-1.6), self-reported history of HPV infection (PR 1.2, 95% CI 0.96-1.6), condom use in the last sexual intercourse (PR 1.3, 95% CI 1.1-1.7), and nadir CD4+ T-cell count <100 cells/mm(3) (PR 1.6, 95% CI 1.2-2.1). Conclusions: The estimated prevalence of high-risk HPV-infection among HIV-infected women from Rio de Janeiro, Brazil, was high. Close monitoring of HPV-related effects is warranted in all HIV-infected women, in particular those of younger age and advanced immunosuppression.

International conference site selection criteria : And a case study of Stockholm as an international conference city

The purpose of this thesis is to identify the destination site selection criteria for internationalconferences from the perspectives of the three main players of the conference industry,conference buyers (organizers and delegates) and suppliers. Additionally, the researchidentifies the strengths and weaknesses of the congress cities of Stockholm and Vienna.Through a comparison with Vienna, the top city for hosting international conferences, a roadmap for Stockholm has been designed, to strengthen its congress tourism opportunities, thus,obtaining a higher status as an international congress city. This qualitative research hascombined both primary and secondary data methods, through semi-standardized expertinterviews and secondary studies respectively, to fulfil the study’s aim. The data have beenanalysed by applying the techniques of qualitative content analysis; the secondary dataadopting an inductive approach according to Mayring (2003) while the expert interviewsusing a deductive approach according to Meuser & Nagel (2009). The conclusions of thesecondary data have been further compared and contrasted with the outcomes of the primarydata, to propose fresh discoveries, clarifications, and concepts related to the site selectioncriteria for international conferences, and for the congress tourism industry of Stockholm. Theresearch discusses the discoveries of the site selection criteria, the implications of thestrengths and weaknesses of Stockholm in comparison to Vienna, recommendations forStockholm via a road map, and future research areas in detail. The findings andrecommendation, not only provide specific steps and inceptions that Stockholm as aninternational conference city can apply, but also propose findings, which can aid conferencebuyers and suppliers to cooperate, to strengthen their marketing strategies and developsuccessful international conferences and destinations to help achieve a greater competitiveadvantage.

O Trabalho e o labirinto da responsabilidade socioempresarial:a experiência da cidadania empresarial do Banco do Brasil

In the current systemic crisis, economic policy is directed to correct the consequences of the functioning of this metabolism, but within the limits of the capital. From this perspective, decision makers propose trade policies, agricultural and industrial to ensure conditions for economic growth. However, as a dead end, there is failure of the State in giving efficacy to the operation of all segments of the economy, especially given the budget constraint. Public managers are forced to seek external resources, resuming the cycle of political allegiance to the interests of international financial and banking representatives, installed in so-called multilateral. The complex ideological capital comes into play in trying to convince society that the paths taken by governments are inevitable, and that capitalism can be "humanized", even with the realization of the growing inequalities caused by historical irrationalism of the production process of capital . In this sense, emerging concepts that attempt to demonstrate the compatibility of the system to real human needs. This ideological offensive is intended to legitimize the capital. The so-called third sector has a special highlight with the concept of corporate social responsibility. It creates a political environment in which the inevitable mix-up with new illusions offered by and often funding the metabolism of capital in order to perpetuate this system. In this context, political elites, and considerable portions of the academy, embark on "waves of capitalist optimism," while the sociometabolismo capital expands its historical limits, driving forces postponing their collapse, but that cause human suffering and ecological stress. Wars are disseminated to strengthen the deadly war industry and the automobile industry; and devastating the environment of which depends the capital system. In this scenario disassemble, propositions emerge around a "new social pact" in order to minimize the adverse effects of the dynamics of reproduction of capital. The business class is called to exercise its role through the discourse that appeals to social responsibility programs, in order to intervene directly in the "social question". The core of this research is precisely this point. Although there is considerable scholarship on the phenomenon of Social Responsibility and Corporate Citizenship, there is also an evident lack of this approach focused on the banking sector in Brazil. The importance of rentier capital increased ownership of shares in the wealth produced by all of Brazilian society, justifies a sociological research project on Social Responsibility in the domestic financial sector. In this sense, it was decided to perform a dynamic approach to the "Corporate Citizenship" in the banking industry, specifically in the Bank of Brazil. As this is a key institution, is important analyze of the impacts of this strategy fetish of capitalist reproduction, in order to evaluate the social legitimization of rentier capital in Brazil. In this scenario of the abundance of the discourse on social responsibility there exist a progressive impoverishment of professional work in this segment in Brazil. There is a dramatic mismatch between rhetoric and practice because of the trend of deepening vulnerability of the working conditions of the Brazilian bank worker, from the 1990's. In the specific case of the Bank of Brazil, the first initiative of the institution was to conform to the principles of the UNO and the Ethos Institute, aiming to align their domestic policies to this new strategy of domination of capital. The purpose is to place the Bank in the ideological sphere of corporate social responsibility, just as with its partners in the private financial intercapitalist competition. Indeed, in the internal ambit of the Bank of Brazil, there is a policy to adjust its functional segments to the doctrine of Social Corporate Responsibility. The concepts of this doctrine is presented as something inexorable. There are no alternatives. The Bank of Brazil operates in a highly competitive market, the segment featuring the dominance of financial capital accumulation today. For this reason it can not fail to incorporate the technological advances organizational. For employees there is no alternative but to adapt to this new set of ideas proposed by the metabolism of capital
