General and mental health of poor and multiproblematic families

The main feature of the so called multiproblem families is the persistence along time of a set of problems in various areas of the individual’s functioning in several family members.This research study aims: a) To identify and characterise the major health problems faced by the members of these families; b) To explore the perceived relevance of these problems; c) To explore the perceived effectiveness of health care interventions received by respondents; d) To explore the level of control perceived over these problems.

Nutritional status and specific leaf area of mahogany and tonka bean under two light environments

Studies on nutritional status and leaf traits were carried out in two tropical tree species Swietenia macrophylla King (mahogany) and Dipetryx odorata Aubl. Willd. (tonka bean) planted under contrasting light environments in Presidente Figueiredo-AM, Brazil. Leaves of S. macrophylla and D. odorata were collected in three year-old trees grown under full sunlight (about 2000 µmol m-2 s-1) and natural shade under a closed canopy of Balsa-wood plantation (Ochroma pyramidale Cav. Ex. Lam.Urb) about 260 µmol m-2 s-1. The parameters analysed were leaf area (LA), leaf dry mass (LDM), specific leaf area (SLA) and leaf nutrient contents. It was observed that, S. macrophylla leaves grown under full sunlight showed LA 35% lower than those grown under shade. In D. odorata leaves these differences in LA were not observed. In addition, it was observed that S. macrophylla shade leaves, for LDM, were 50% smaller than sun leaves, while in D. odorata, there differences were not observed. SLA in S. macrophylla presented that sun leaves were three times smaller than those grown under shade. In D. odorata, no differences were observed. Nutrient contents in S. macrophylla, regardless of their light environments, showed higher contents for P and Ca than those found in D. odorata. The N, K, Fe and Mn contents in S. macrophylla leaves decreased under shade. Finally, we suggest that the decreasing in leaf nutrient contents may have a negative influence on leaf growth. The results demonstrated that the tested hypothesis is true for leaf traits, which D. odorata, late-successional species, showed lower plasticity for leaf traits than Swietenia macrophylla, mid-successional species.

Migration and mental health: Japanese Brazilians in Japan and in Brazil

OBJECTIVE: Brazil is the country with the largest community of Japanese descendants in the world, from a migration movement that started in 1908. However, more recently (1988), a movement in the opposite direction began. Many of these descendants went to Japan for work purposes and suffered mental distress. Some of them sought treatment in Japan, while others returned to Brazil to seek treatment. The aim of the present study was to compare the sociodemographic profile and diagnoses of Japanese Brazilian psychiatric outpatients in Japan (remaining group) and in Brazil (returning group). METHOD: All consecutive Japanese Brazilian outpatients who received care from the psychiatric units in Japan and Brazil from April 1997 to April 2000 were compared. The diagnoses were based on ICD-10 and were made by psychiatrists. Sociodemographic data and diagnoses in Brazil and Japan were compared by means of the Chi-Squared Test. RESULTS: The individuals who returned to Brazil were mostly male and unmarried, had lived alone in Japan, had stayed there for short periods and were classified in the schizophrenia group. The individuals who remained in Japan were mostly female and married, were living with family or friends, had stayed there for long periods and were classified in the anxiety group. Logistic regression showed that the most significant factors associated with the returning group were that they had lived alone and stayed for short periods (OR = 0.93 and 40.21, respectively). CONCLUSION: We conclude that living with a family and having a network of friends is very important for mental health in the context evaluated.

Assessing cardiorespiratory capacity in older adults with major depression and Alzheimer disease

ABSTRACT Objective To assess cardiorespiratory capacity through subjective and objective tests in older adults diagnosed with major depression (MDD), Alzheimer disease (AD) and healthy older adults. Methods Fifty seven subjects (72 ± 7.9 years) were divided into three groups: MDD (n = 20), AD (n = 17) and Healthy (n = 20). The subjects answered Hamilton Scale (HAM-D), Mini-Mental State Examination (MMSE), Veterans Specific Activity Questionnaire (VSAQ) and 2-minute Step test. Results MDD and AD showed lower scores than healthy group for Nomogram VSAQ (p < 0.001) and 2-minute Step (p = 0.009; p = 0.008, respectively). Adjusted for age and educational level, no differences among groups were observed for Step (MDD, p = 0.097; AD, p = 0.102). AD group did not present differences to healthy group for Step, when adjusting for MMSE (p = 0.261). Conclusions Despite the lower cardiorespiratory fitness of elderly patients with DM and DA have been found in both evaluations, the results should be viewed with caution, since the tests showed low correlation and different risk classifications of functional loss. In addition, age, level educational and cognitive performance are variables that can influence the performance objective evaluation.

Producción de información para las políticas públicas: observatorio de salud mental y derechos humanos en la provincia de córdoba. Documented information and indicators for the pubic policies in mental health: human rights obseratory in córdoba

El problema que enfrenta la institucionalidad estatal argentina es que existe un serio déficit de información no solamente en el momento de evaluar un resultado, sino ya al momento de diseñar la política. Las estadísticas oficiales de hechos vitales, salud y educación son difundidas en el mejor de los casos con un año de atraso. La información de indicadores de salud por su nivel de desagregación no permite conocer las realidades locales. Es posible constatar la falta de información sobre las medidas tomadas para asegurar el cumplimiento de las obligaciones del Estado en lo relativo a políticas y programas de salud mental. Del mismo modo que los organismos internacionales determinan los deficits de los sistemas de atención a la salud mental a través de las brechas de tratamiento y aun cuando no se dispone de estimaciones precisas se habla de brechas de información, que expresarían la distancia entre la información necesaria y la efectivamente disponible (OPS, 2009). Desde el mes de diciembre de 2007 se conforma la Mesa de Trabajo Permanente en Salud Mental y Derechos Humanos, con el objeto de instalar en agenda la necesidad de contar con una legislación que brinde el marco normativo para la transformación del sector. En los meses de octubre y noviembre de 2010 se aprobaron sendas leyes de salud mental en la Provincia de Córdoba y a nivel nacional. Ambas proponen la transformación progresiva en los sistemas de atención a los problemas de salud mental de la población. Desde la Mesa de Trabajo Permanente en Salud Mental y Derechos Humanos se afirma que la legislación es un marco necesario pero no suficiente, en tanto se constata que las princiales violaciones a los derechos humanos se producen en situaciones concretas. El presente proyecto nace de la necesidad de contar con un sistema de información que permita conocer la transformación de los servicios de salud mental en la provincia de Córdoba a partir de la sanción de la ley 9848 de Salud Mental en el mes de octubre de 2010. Una vez logrado este objetivo legislativo, se pretende monitorear la gestión con la formulación de los siguientes interrogantes: ¿a través de qué indicadores medir, evaluar y monitorear si la producción de los servicios de salud mental se lleva adelante desde la perspectiva del enfoque de derechos sancionada en el marco normativo vigente?; ¿cuáles son los indicadores que desde dicha perspectiva los organismos estatales de producción de servicios deben elaborar para el compromiso de acción y la rendición de cuentas frente a la ciudadanía? ¿cuáles son los indicadores que la ciudadanía debe reclamar a los fines de monitorear el cumplimiento de dichos compromisos? La puesta en marcha del Observatorio de Salud Mental y Derechos Humanos permitirá analizar las políticas y programas de salud mental desde la perspectiva de los derechos humanos y avanzar en el monitoreo de la producción de los servicios de salud mental. Objetivo General: analizar y hacer visible el cumplimiento de los objetivos sancionados en la ley 9848 de Salud Mental a través de la observación, el monitoreo y la incidencia en las políticas de salud mental de la provincia de Córdoba. Metodología: la construcción de indicadores de derechos humanos para la salud mental. El Observatorio de Salud Mental y Derechos Humanos pretende dar cuenta de las transformaciones que van a ocurrir a partir de la sanción de la ley 9848. Los resultados esperados están ligados a la producción y difusión de información sistematizada sobre las transformaciones en salud mental, a la vigilancia y el análisis del efecto/impacto de las políticas e incidir en las decisiones. El Observatorio pretende reconocer e integrar la información disponible y proponer indicadores que den cuenta de la situación inicial al momento de la implementación de los marcos normativos y permitir el monitoreo de las transformaciones emergentes. This project stems from the need for an information system designed to show the transformation of mental health services in the province of Cordoba after the enactment of the Mental Health Act 9848 in October 2010. Once achieved this legislative objective is to monitor the management with the formulation of the following questions: through which indicators to measure, evaluate and monitor whether the production of mental health services are carried forward from the perspective of rights-based approach enacted in two laws?, What are the indicators from that perspective the production agencies should develop services for the commitment to action and accountability to the public? What are the indicators that the public should demand that the purpose of monitoring compliance with these commitments? The launch of the Centre for Mental Health and Human Rights will review the policies and mental health programs from the perspective of human rights and progress in monitoring the production of mental health services. General Objective: to analyze and highlight the achievement of the objectives sanctioned by the Mental Health Act 9848 through the observation, monitoring and impact on mental health policy in the province of Cordoba. Methodology: building human rights indicators for mental health Mental Observatory Health and Human Rights aims to account for the changes that will occur after the enactment of Law 9848. The expected results are linked to production and dissemination of systematic information about changes in mental health, surveillance and analysis of the effect / impact and influence policy decisions. The Centre aims to recognize and integrate the available information and propose indicators that account for the initial situation at the time of implementation of regulatory frameworks and allow monitoring of change emerging.

Can genetic algorithms explain experimental anomalies? An application to common property resources

It is common to find in experimental data persistent oscillations in the aggregate outcomes and high levels of heterogeneity in individual behavior. Furthermore, it is not unusual to find significant deviations from aggregate Nash equilibrium predictions. In this paper, we employ an evolutionary model with boundedly rational agents to explain these findings. We use data from common property resource experiments (Casari and Plott, 2003). Instead of positing individual-specific utility functions, we model decision makers as selfish and identical. Agent interaction is simulated using an individual learning genetic algorithm, where agents have constraints in their working memory, a limited ability to maximize, and experiment with new strategies. We show that the model replicates most of the patterns that can be found in common property resource experiments.

The role of Notch in the differentiation of CD4⁺ T helper cells.

CD4⁺ T helper cells are playing critical roles in host defense to pathogens and in the maintenance of immune homeostasis. Naïve CD4⁺T cells, upon antigen-specific recognition, receive signals to differentiate into distinct effector T helper cell subsets characterized by their pattern of cytokine production and specific immune functions. A tight balance between these different subsets ensures proper control of the immune response. There is increasing evidence revealing an important role for Notch signaling in the regulation of CD4⁺T helper cell differentiation or function in the periphery. However, the exact mechanisms involved remain unclear and appear contradictory. In this review, we summarize current knowledge and discuss recent advances in the field to reconcile different views on the role of Notch signaling in the differentiation of functional T helper subsets.

Involvement of PPARβ/δ in mesenchymal-epidermal interactions during skin wound healing

SUMMARY : Skin wound repair is a complex and highly coordinated process, where a variety of cell types unite to regenerate the damaged tissue. Several works have elucidated cellular and molecular mechanisms, in which mesenchymal-epidermal interactions play an essential role for the regulation of skin homeostasis and repair. Peroxisome Proliferator-Activated Receptors (PPARs) are ligand-activated transcription factors that belong to the nuclear receptor superfamily. Three related isotypes (PPARα, PPARß/δ and PPARγ) have been found, which exhibit distinct tissue distribution and specific physiological functions. PPARß/δ was identified as a crucial player of skin homeostasis. In the mouse skin, PPARß/δ has been described to control proliferation-differentiation state, adhesion and migration, and survival of the keratinocytes during healing. PPARß/δ has been implicated as well in the development of the hair follicles, in which mesenchymal-secreted hepatocyte growth factor (HGF) is involved. These data suggest that the biological activity of PPARß/δ is modulated by mesenchymal-epidermal interactions and that, in turn, PPARß/δ also modulates some of these signals. The aim of the present work was to elucidate the nature of the signals exchanged between the epidermis and dermis compartments, and more particularly those which are under the control of PPARß/δ. In the first part of the study, we showed that PPARß/8 in dermal fibroblasts down-regulates the mitotic activity of keratinocytes by inhibiting the IL-1 signalling pathway via the production of secreted IL-1 receptor antagonist (sIL-1Ra), a natural antagonist of this signalling. The regulation of IL-1 signalling by PPARß/δ is required for anon-pathological skin wound repair. These findings provide evidence for a novel homeostatic control of keratinocyte proliferation and differentiation mediated by the regulation of IL-1 signalling via dermal PPARß/δ fibroblasts. Proteolysis of the extracellular matrix (ECM) is a key process involved in wound repair and modifications in its activity are often associated with an alteration óf the wound closure. This process implies specific proteinases, as matrix metalloproteinases (MMPs), which are finely modulated by IL-1 signalling. In line with the first results, the second part of the work showed that MMP8 and MMP13, which are two important collagenases involved in mouse skin wound repair, are regulated by PPARß/δ. Their expression is indirectly down-regulated by dermal PPARß/δ, via the production of sIL-1Ra, resulting in the inhibition of IL-1 signalling, known to regulate the expression of numerous MMPs. We suggest that, in absence of PPARß/δ, the positive regulation of these two collagenases could participate to the delay of skin wound healing, which has been observed in mice deleted for PPARßlS. The potential therapeutic role of PPARß/b could be as well extending to inflammatory and hyperproliferative skin diseases involving IL-1 signalling, such as psoriasis or skin cancers. Quite interestingly, MMP1 (analogue of mouse MMP13) plays an essential role in human photoaging, suggesting that PPARß/δ could as well be an attractive target for photoprotection. RESUME : La cicatrisation est un processus complexe et extrêmement organisé, impliquant un grand nombre de cellules qui s'unissent pour régénérer le tissu endommagé. De nombreux travaux nous ont éclairés sur les mécanismes cellulaires et moléculaires, dans lesquels les interactions épidermo-mésenchymateuses détiennent un rôle capital à la fois dans la régulation de l'homéostasie et dans la réparation de la peau. PPAR (Peroxisome proliferatar-activated receptor), qui appartient à la superfamille des récepteurs nucléaires, se définit comme un facteur de transcription activé par des ligands très spécifiques. Trois isotypes (PPARa, PPARß/δ et PPARy) ont été décrits et sont caractérisés par une distribution tissulaire et des fonctions physiologiques clairement définies. PPARß/δ a été identifié comme étant un important acteur dans l'homéostasie de la peau. Chez la souris, il a été décrit comme contrôlant l'état de prolifération et de différenciation, le processus d'adhésion et de migration, ainsi que la survie des kératinocytes au cours de la cicatrisation. PPARßIS a également été défini comme contrôlant le développement des follicules pileux, impliquant la sécrétion par le mésenchyme du facteur de croissance HGF. Ces données suggèrent que l'activité biologique de PPARß/δ est modulée par des interactions épidermo-mésenchymateuses, et qu'en retour, il possède la capacité de moduler certains de ces signaux. L`objectif de ce travail a été d'élucider la nature des signaux échangés entre les compartiments épidermique et dermique, et plus particulièrement ceux qui sont sous le contrôle de PPARß/δ. Dans la première partie de l'étude, nous avons montré que les fibroblastes exprimant PPARß/δ réduisent l'activité mitotique des kératinocytes en inhibant la voie de signalisation IL-1, via la production de sIL-1Ra (secreted IL-1 receptor antagonist), défini comme un antagoniste naturel de cette voie de signalisation. La régulation de cette dernière par PPARß/δ est donc nécessaire pour une cicatrisation de type non pathologique. Ces résultats offrent donc une nouvelle preuve du contrôle de l'homéostasie et de l'état de prolifération/différenciation des kératinocytes par les fibroblastes exprimant PPARß/δ, en régulant la voie de signalisation IL-1. Le mécanisme de dégradation de la matrice extracellulaire (MEC) est une étape essentielle lors du processus de cicatrisation. Ainsi des modifications de cette activité protéolytïque sont souvent associées à une altération de la fermeture de la plaie. Ce processus implique des protéinases, comme les MMPs, qui sont finement modulés par la voie de signalisation IL-1. En accord avec les premiers résultats, la seconde partie des nos travaux a montré que les collagénases MMP8 et MMP13, connues pour être d'importantes molécules impliquées lors de la réparation tissulaire chez la souris, sont modulées par l'activité de PPARß/δ. Leurs expressions sont indirectement régulées par PPARß/δ, via la production. de sIL-1 Ra, entraînant ainsi l'inhibition de la voie de signalisation IL-1, décrite pour réguler l'expression de nombreuses MMPs, Nous suggérons donc qu'en absence de PPARß/δ, la régulation de ces deux collagénases pourrait être impliquée dans le retard de cicatrisation, observé chez les souris déficientes pour PPARß/δ. L'activité biologique de PPARß/δ pourrait être ainsi étendue à des maladies hyperproliferatives et inflammatoires de la peau, impliquant la voie de signalisation IL-1, comme le psoriasis ou certains cancers de la peau, et ce à des fins thérapeutiques. Il est aussi intéressant de relever que chez l'homme, MMP1 (présenté comme l'analogue de MMP13 de la souris} joue un rôle primordial dans le photo-vieillissement, nous suggérons donc que PPARß/δ pourrait ainsi être une cible attrayante concernant la photoprotection.

Facilitated glucose transporters in epithelial cells.

The molecular cloning of facilitated sugar transporters has led to the identification of a family of transport molecules having similar functions, but possessing specific kinetic and regulatory properties. These transporter isoforms are characterized by different primary structures, specific tissue localization, and polarized expression within the same epithelial cells. The use of Xenopus oocytes for the functional expression of different members of this transporter family has been of considerable value in defining the kinetic properties and sugar specificities of the different isoforms. The expression of chimeric or variously mutated transporters should, in the near future, permit the determination of the structural basis for their kinetic properties and sugar specificities. cDNA probes and antipeptide antibodies specific for each isoform are now being used to determine their specific regulation during development and in different states of altered glucose homeostasis. The variety of molecular forms implicated in the apparently simple task of sugar uptake or transepithelial transport has been surprising. With the available molecular tools now in hand, it will be possible to study these mechanisms in much greater detail.

The yellow fever 17D vaccine virus as a vector for the expression of foreign proteins: development of new live flavivirus vaccines

The Flaviviridae is a family of about 70 mostly arthropod-borne viruses many of which are major public health problems with members being present in most continents. Among the most important are yellow fever (YF), dengue with its four serotypes and Japanese encephalitis virus. A live attenuated virus is used as a cost effective, safe and efficacious vaccine against YF but no other live flavivirus vaccines have been licensed. The rise of recombinant DNA technology and its application to study flavivirus genome structure and expression has opened new possibilities for flavivirus vaccine development. One new approach is the use of cDNAs encopassing the whole viral genome to generate infectious RNA after in vitro transcription. This methodology allows the genetic mapping of specific viral functions and the design of viral mutants with considerable potential as new live attenuated viruses. The use of infectious cDNA as a carrier for heterologous antigens is gaining importance as chimeric viruses are shown to be viable, immunogenic and less virulent as compared to the parental viruses. The use of DNA to overcome mutation rates intrinsic of RNA virus populations in conjunction with vaccine production in cell culture should improve the reliability and lower the cost for production of live attenuated vaccines. The YF virus despite a long period ignored by researchers probably due to the effectiveness of the vaccine has made a come back, both in nature as human populations grow and reach endemic areas as well as in the laboratory being a suitable model to understand the biology of flaviviruses in general and providing new alternatives for vaccine development through the use of the 17D vaccine strain.

Specific antibody levels and antigenic recognition of Wistar rats inoculated with distinct isolates of Trypanosoma evansi

"Mal de Cadeiras", an enzootic disease caused by Trypanosoma evansi, is one of the most important trypanosomiases in the Brazilian Pantanal region. The disease affects mainly horses, which are widely used in extensive cattle production, an activity of greatest economical significance for the region. The parasite also infects sylvan (coatis and capybaras) and domestic (dogs) animals, respectively considered wild and domestic reservoirs of T. evansi. For a better understanding of the interaction of T. evansi with its rodent host, we evaluated the differences in the specific antibody level patterns and in the parasitic peptides recognition patterns of experimentally infected Wistar rats. The rats experimentally infected with T. evansi isolates obtained from coatis, dogs and horses were submitted to indirect immunofluorescence test (IgM e IgG) and Western blotting. The serological titers for IgM and IgG ranged between 1:40 and 1:160. The most recognized polypeptide profiles were in a range of 17 and 74 kDa. Our data suggest that the humoral immune response in Wistar rats is not sufficient for granting an effective control of T. evansi infections.

Classification of human astrocytic gliomas on the basis of gene expression: a correlated group of genes with angiogenic activity emerges as a strong predictor of subtypes.

The development of targeted treatment strategies adapted to individual patients requires identification of the different tumor classes according to their biology and prognosis. We focus here on the molecular aspects underlying these differences, in terms of sets of genes that control pathogenesis of the different subtypes of astrocytic glioma. By performing cDNA-array analysis of 53 patient biopsies, comprising low-grade astrocytoma, secondary glioblastoma (respective recurrent high-grade tumors), and newly diagnosed primary glioblastoma, we demonstrate that human gliomas can be differentiated according to their gene expression. We found that low-grade astrocytoma have the most specific and similar expression profiles, whereas primary glioblastoma exhibit much larger variation between tumors. Secondary glioblastoma display features of both other groups. We identified several sets of genes with relatively highly correlated expression within groups that: (a). can be associated with specific biological functions; and (b). effectively differentiate tumor class. One prominent gene cluster discriminating primary versus nonprimary glioblastoma comprises mostly genes involved in angiogenesis, including VEGF fms-related tyrosine kinase 1 but also IGFBP2, that has not yet been directly linked to angiogenesis. In situ hybridization demonstrating coexpression of IGFBP2 and VEGF in pseudopalisading cells surrounding tumor necrosis provided further evidence for a possible involvement of IGFBP2 in angiogenesis. The separating groups of genes were found by the unsupervised coupled two-way clustering method, and their classification power was validated by a supervised construction of a nearly perfect glioma classifier.

Implementing A vision for change: moving towards a modern, quality and responsive mental health service. Carlow / Kilkenny / South Tipperary.

The key element of the HSE South’s Programme is to enhance and develop community mental health services in Carlow, Kilkenny and South Tipperary, to enable the service user to remain in the community to the greatest extent possible. HSE South has prioritised the implementation of the change programme and has allocated more than €20m capital funding and over €1.75m revenue funding to support this comprehensive development programme. Speaking at the briefings Mr. Pat Healy, Regional Director of Operations, HSE South said, “When this plan is delivered, clients will have access to the highest standards of services in all three counties, which should significantly improve these clients’ treatment programmes and quality of life. The National Service Users Executive are supporting the change programme, which is of immense importance to HSE South. The programme heralds the enhancement and development of community mental health services, the closure of old long stay institutions, the separation of North and South Tipperary acute inpatient mental health services and development of appropriate acute inpatient services, for the extended catchment area, in line with the national strategy for mental health “A Vision for Change”. The programme also acts on recommendations of the Mental Health Commission.”This resource was contributed by The National Documentation Centre on Drug Use.
