En este estudio de caso pretende dar respuesta a que factores vitalizan la cooperación Española en Mozambique a través del análisis de programas como el VITA, dirigidos específicamente al desarrollo y mejoramiento de la salud en el continente Africano. Este estudio de caso se centra en el investigación de los discursos de desarrollo que se fundamentan en las políticas internacionales de cooperación , basadas en la existencia de una enfermedad como el VIH que ha puesto en manifiesto la interacción entre la esfera biológica y social , social e individual entre el fenómeno existencial y cultural, lo que fundamenta su importancia y estudio. Se ha escogido esta herramienta de investigación social, en este estudio de caso, para abordar la forma en que funciona y opera la AECID en Mozambique a través de los programas con enfoque de género encaminados al problema del VIH. Se pretende dar a conocer el desarrollo en materia de la cooperación internacional de una organización tan importante como la AECID, cuyos proyectos gozan de una gran credibilidad en cuanto a la ejecución de sus acciones y que en general dichos proyectos se adecuan a las necesidades de la población, a los objetivos de desarrollo nacionales y a las prioridades de la cooperación española.

El propósito central del artículo es el de analizar qué tipo de sentimientos morales serían los que deberían despertar los testimonios de las víctimas en los miembros de una comunidad política que pretende ser democrática, incluyente y respetuosa de los derechos humanos. De la mano de Avishai Margalit, Tzvetan Todorov, Peter Strawson, Martha Nussbaum, Elizabeth Spelman y Manuel Reyes Mate, a lo largo del texto defenderemos la tesis de que las narraciones y representaciones del sufrimiento injusto padecido por las víctimas son aquellas que son capaces de despertar una indignación y compasión informada en los ciudadanos. Para mostrar el alcance y significado de esta tesis, nos centraremos en analizar dos de los problemas más serios a los que se enfrenta una política de la memoria que privilegia a las víctimas. El primero de ellos tiene que ver con los riesgos que se presentan por las distorsiones que son usuales en los relatos de las víctimas y que en buena parte están ligadas a una especie de sacralidad que se les atribuye a quienes atestiguan acerca de la violencia que han padecido. El segundo problema que analizaremos está relacionado con la recepción e interpretación que hacen los miembros de la comunidad política acerca de ese sufrimiento. En concreto, discutiremos los distintas formas de banalización que pueden darse entre los ciudadanos al momento de interpretar las narraciones que representan el daño. En la última parte del texto, analizaremos el testimonio ejemplar de Harriet Jacobs con el fin de mostrar de que manera un testimonio puede generar en su audiencia sentimientos de indignación y compasión informadas.

Introducción: La melatonina, una sustancia cronobiótica endógena, es cada vez más empleada para el manejo de los problemas del sueño en adultos mayores por su aparente eficacia y buen perfil de eventos adversos. En este sentido, se intentó evaluar la eficacia de la melatonina en el tratamiento del insomnio primario en el adulto mayor (≥55 años) comparado con benzodiacepinas, zopiclona y placebo a la luz de la evidencia disponible en los últimos cinco años. Métodos: Revisión sistemática de la literatura. Resultados: En comparación con placebo, al parecer la melatonina mejora la calidad y los hábitos de sueño, no así la latencia de inicio de sueño en mediciones subjetivas ni objetivas (polisomnografía); a diferencia de otros medicamentos hipnóticos, no altera la arquitectura del sueño ni genera síntomas diurnos. Conclusiones: No se encontró evidencia que soporte el uso de melatonina en adultos mayores de 55 años para la reducción de la latencia de sueño, aumento del tiempo total de sueño, mejoría de la eficiencia del sueño, disminución de despertares nocturnos o mejoría de la calidad de sueño. Es necesario adelantar más estudios en comparación con placebo y otros medicamentos.

El problema del cambio climático ha llegado a formar parte prioritaria de las agendas políticas. Se trata de un Cambio Global que está interconectado a otras cuestiones globales y debe ser abordado con las herramientas que permitan observar su carácter complejo. Las transformaciones en curso están causadas fundamentalmente por la acción humana, por lo que deben ser afrontadas por la sociedad convirtiendo los desafíos del cambio climático en desafíos sociales. La confirmación de que existen otras maneras de entender la relación entre naturaleza y sociedad puede ayudar a solucionar el problema de forma integral e interdisciplinar.

Using a free-air CO2 enrichment (FACE) experiment, poplar trees (Populus · euramericana clone I214) were exposed to either ambient or elevated [CO2] from planting, for a 5-year period during canopy development, closure, coppice and re-growth. In each year, measurements were taken of stomatal density (SD, number mm2) and stomatal index (SI, the proportion of epidermal cells forming stomata). In year 5, measurements were also taken of leaf stomatal conductance (gs, lmol m2 s1), photosynthetic CO2 fixation (A, mmol m2 s1), instantaneous water-use efficiency (A/E) and the ratio of intercellular to atmospheric CO2 (Ci:Ca). Elevated [CO2] caused reductions in SI in the first year, and in SD in the first 2 years, when the canopy was largely open. In following years, when the canopy had closed, elevated [CO2] had no detectable effects on stomatal numbers or index. In contrast, even after 5 years of exposure to elevated [CO2], gs was reduced, A/E was stimulated, and Ci:Ca was reduced relative to ambient [CO2]. These outcomes from the long-term realistic field conditions of this forest FACE experiment suggest that stomatal numbers (SD and SI) had no role in determining the improved instantaneous leaf-level efficiency of water use under elevated [CO2]. We propose that altered cuticular development during canopy closure may partially explain the changing response of stomata to elevated [CO2], although the mechanism for this remains obscure.

Sesquiterpenoids, and specifically sesquiterpene lactones from Asteraceae, may play a highly significant role in human health, both as part of a balanced diet and as pharmaceutical agents, due to their potential for the treatment of cardiovascular disease and cancer. This review highlights the role of sesquiterpene lactones endogenously in the plants that produce them, and explores mechanisms by which they interact in animal and human consumers of these plants. Several mechanisms are proposed for the reduction of inflammation and tumorigenesis at potentially achievable levels in humans. Plants can be classified by their specific array of produced sesquiterpene lactones, showing high levels of translational control. Studies of folk medicines implicate sesquiterpene lactones as the active ingredient in many treatments for other ailments such as diarrhea, burns, influenza, and neurodegradation. In addition to the anti-inflammatory response, sesquiterpene lactones have been found to sensitize tumor cells to conventional drug treatments. This review explores the varied ecological roles of sesquiterpenes in the plant producer, depending upon the plant and the compound. These include allelopathy with other plants, insects, and microbes, thereby causing behavioural or developmental modification to these secondary organisms to the benefit of the sesquiterpenoid producer. Some sesquiterpenoid lactones are antimicrobial, disrupting the cell wall of fungi and invasive bacteria, whereas others protect the plant from environmental stresses that would otherwise cause oxidative damage. Many of the compounds are effective due to their bitter flavor, which has obvious implications for human consumers. The implications of sesquiterpenoid lactone qualitiesfor future crop production are discussed.

Older people increasingly want to remain living independently in their own homes. The aim of the ENABLE project is to develop a wearable device that can be used to support older people in their daily lives and which can monitor their health status, detect potential problems, provide activity reminders and offer communication and alarm services. In order to determine the specifications and functionality required for the development of the device, user surveys and focus groups were undertaken, use case analysis and scenario modeling carried out. The project has resulted in the development of a wrist-worn device and mobile phone combination that can support and assist older and vulnerable wearers with a range of activities and services both inside their home and as they move around their local environment. The device is currently undergoing pilot trials in five European countries. The aim of this paper is to describe the ENABLE device, its features and services, and the infrastructure within which it operates.

Objective: Obsessive-compulsive disorder (OCD) in young people can be effectively treated with Cognitive Behavior Therapy (CBT). Practice guidelines in the United Kingdom recommend that CBT be delivered with parental or family involvement; however, there is no evidence from randomized trials that this enhances effectiveness. The aim of this trial was to assess if CBT with high parental involvement was more effective than CBT with low parental involvement (individual CBT) in reducing symptoms of OCD. Method: Fifty young people ages 12–17 years with OCD were randomly allocated to individual CBT or parent-enhanced CBT. In parent-enhanced CBT parents attended all treatment sessions; in individual CBT, parents attended only Sessions 1, 7, and the final session. Participants received up to 14 sessions of CBT. Data were analyzed using intent-to-treat and per-protocol methods. The primary outcome measure was the Children’s Yale-Brown Obsessive Compulsion Scale (Scahill et al., 1997). Results: Both forms of CBT significantly reduced symptoms of OCD and anxiety. Change in OCD symptoms was maintained at 6 months. Per-protocol analysis suggested that parent-enhanced CBT may be associated with significantly larger reductions in anxiety symptoms. Conclusions: High and low parental involvement in CBT for OCD in young people were both effective, and there was no evidence that 1 method of delivery was superior on the primary outcome measure. However, this study was small. Future trials should be adequately powered and examine interactions with the age of the young person and comorbid anxiety disorders.

Background Major Depressive Disorder (MDD) is among the most prevalent and disabling medical conditions worldwide. Identification of clinical and biological markers (“biomarkers”) of treatment response could personalize clinical decisions and lead to better outcomes. This paper describes the aims, design, and methods of a discovery study of biomarkers in antidepressant treatment response, conducted by the Canadian Biomarker Integration Network in Depression (CAN-BIND). The CAN-BIND research program investigates and identifies biomarkers that help to predict outcomes in patients with MDD treated with antidepressant medication. The primary objective of this initial study (known as CAN-BIND-1) is to identify individual and integrated neuroimaging, electrophysiological, molecular, and clinical predictors of response to sequential antidepressant monotherapy and adjunctive therapy in MDD. Methods CAN-BIND-1 is a multisite initiative involving 6 academic health centres working collaboratively with other universities and research centres. In the 16-week protocol, patients with MDD are treated with a first-line antidepressant (escitalopram 10–20 mg/d) that, if clinically warranted after eight weeks, is augmented with an evidence-based, add-on medication (aripiprazole 2–10 mg/d). Comprehensive datasets are obtained using clinical rating scales; behavioural, dimensional, and functioning/quality of life measures; neurocognitive testing; genomic, genetic, and proteomic profiling from blood samples; combined structural and functional magnetic resonance imaging; and electroencephalography. De-identified data from all sites are aggregated within a secure neuroinformatics platform for data integration, management, storage, and analyses. Statistical analyses will include multivariate and machine-learning techniques to identify predictors, moderators, and mediators of treatment response. Discussion From June 2013 to February 2015, a cohort of 134 participants (85 outpatients with MDD and 49 healthy participants) has been evaluated at baseline. The clinical characteristics of this cohort are similar to other studies of MDD. Recruitment at all sites is ongoing to a target sample of 290 participants. CAN-BIND will identify biomarkers of treatment response in MDD through extensive clinical, molecular, and imaging assessments, in order to improve treatment practice and clinical outcomes. It will also create an innovative, robust platform and database for future research.
