Retention half times in the skeleton of plutonium and 90Sr from above-ground nuclear tests: a retrospective study of the Swiss population.

Plutonium and (90)Sr are considered to be among the most radiotoxic nuclides produced by the nuclear fission process. In spite of numerous studies on mammals and humans there is still no general agreement on the retention half time of both radionuclides in the skeleton in the general population. Here we determined plutonium and (90)Sr in human vertebrae in individuals deceased between 1960 and 2004 in Switzerland. Plutonium was measured by sensitive SF-ICP-MS techniques and (90)Sr by radiometric methods. We compared our results to the ones obtained for other environmental compartments to reveal the retention half time of NBT fallout (239)Pu and (90)Sr in trabecular bones of the Swiss population. Results show that plutonium has a retention half time of 40+/-14 years. In contrast (90)Sr has a shorter retention half time of 13.5+/-1.0 years. Moreover (90)Sr retention half time in vertebrae is shown to be linked to the retention half time in food and other environmental compartments. These findings demonstrate that the renewal of the vertebrae through calcium homeostatic control is faster for (90)Sr excretion than for plutonium excretion. The precise determination of the retention half time of plutonium in the skeleton will improve the biokinetic model of plutonium metabolism in humans.

Comment to "Weak instruments robust tests in GMM and the New Keynesian Phillips curve" by Frank Kleibergen and Sophocles Mavroeidis

I discuss the identifiability of a structural New Keynesian Phillips curve when it is embedded in a small scale dynamic stochastic general equilibrium model. Identification problems emerge because not all the structural parameters are recoverable from the semi-structural ones and because the objective functions I consider are poorly behaved. The solution and the moment mappings are responsible for the problems.

Predictors and Moderators of Clinical Outcomes in Adolescents with Severe Mental Disorders After an Assertive Community Treatment.

Previous studies have shown that stressful life events (SLEs), gender, social functioning and pretreatment severity are some of the predictors and/or moderators of treatment outcome in psychiatric care. The current study explored the effect of these predictors and moderators on the treatment outcome related to assertive community treatment (ACT) proposed to young people with severe mental disorders. 98 patients were assessed for externalizing and emotional difficulties, at admission and then at discharge of an ACT. Analyses revealed significant improvements in terms of symptomatology. In particular, regression analyses showed that pretreatment severity is a significant predictor of the outcome on emotional symptoms and is moderated by SLE on the outcome on externalizing symptoms. Furthermore, higher social functioning proved to predict better outcome on externalizing symptoms. Our results further evidence that these factors can explain inter-individual differences in outcome related to ACT. The theoretical and clinical implications of these results are discussed.

Representação social da doença mental: o olhar da família do portador de esquizofrenia

Este trabalho de investigação aborda a questão da representação social da doença mental entre familiares de pacientes diagnosticados com esquizofrenia, um aspecto necessário e fundamental para a nossa futura prática clínica. O objectivo era compreender a forma como representam a doença mental e o seu portador, e o trabalho teve como referencial vários autores que retractam a representação social da doença mental nas suas várias dimensões: significado, causas e cura da doença mental, ocupação, tomada da medicação, e futuro do portador de distúrbio psíquico. Os dados foram recolhidos mediante uma entrevista aos familiares, realizada em casa dos pacientes. Para o efeito foi desenvolvido um guião de entrevista. Foram recrutados 6 famílias dos portadores de esquizofrenia entre os utentes actuais do Hospital Agostinho Neto – “Extensão Trindade”. As entrevistas foram posteriormente transcritas e os discursos sobre as várias dimensões da representação social foram categorizados. As famílias se posicionaram caracterizando a doença mental e o seu portador segundo as representações do senso comum, pelo que concluímos que elas têm pouca informação médica e compreensão da real condição psíquica do seu familiar. O significado que a família atribuía à doença mental e à sua causa não foi influenciado pelo nível de escolaridade das famílias, mas sim corresponde aos valores culturais da sociedade cabo-verdiana. A partir desta investigação, percebemos a importância de assistir e informar os familiares que acompanham o doente mental, durante o seu tratamento.

A integração do portador de transtorno mental na família

O presente estudo visa reflectir sobre a percepção do portador de transtorno mental sobre a sua integração na família, identificando e analisando vários factores que podem exercer um papel determinante na sua integração. Neste sentido, buscamos problematizar a integração do portador de transtorno mental, tendo em vista o funcionamento da família e as suas condições socioeconómicas, a relação que mantém com os serviços cuidadores, bem como as políticas públicas implementadas, com o objectivo de debelar o problema de transtorno mental. A nossa pesquisa foi realizada no Hospital Trindade, situada na cidade da Praia, extensão do Hospital Agostinho Neto e que tem acolhido e tratado sobretudo os portadores de transtorno mental. Para a colecta de dados, realizamos entrevistas a quinze portadores de transtorno mental e às respectivas famílias, onde focamos os aspectos cruciais para o nosso intento: na entrevista aos pacientes, realçamos a forma como convivem com os outros, com especial atenção para a relação familiar, já que pretendemos elucidar a forma como percebem a sua integração na família; na entrevista aos familiares, sublinhamos também a forma como vêm a relação com o seu portador de transtorno mental, mas quisemos dar um enfoque especial à forma como a família percebe os vários apoios, quer das diferentes instituições, quer do Estado, na medida em que sozinha, tendo em vista uma grande sobrecarga – frise-se os aspectos emocionais e socioeconómicos – não poderá tratar do seu familiar portador de transtorno mental. Assim, a partir dos aspectos supracitados, inferimos que, não obstante os preconceitos socialmente arraigados, apesar de o Estado estar aquém do seu papel, seja na implementação de políticas públicas direccionadas ao portador de transtorno mental, seja no apoio às famílias, e, ainda, apesar de não haver uma verdadeira inclusão da família, no processo de tratamento, os portadores de transtorno mental, em geral, querem estar no seu próprio seio familiar, o que nos leva a pensar que é o espaço onde, de facto, se sentem bem.

Governor's Task Force on Dependent Adults with Mental Retardation Final Report, 2009

On February 17, 2009, Governor Culver signed Executive Order No. 11 to create a Task Force on Dependent Adults with Mental Retardation. The executive order charges the Task Force with the responsibility of recommending steps to strengthen and improve state laws and regulations on the care and treatment of dependent adults with mental retardation. The Final Report includes recommendations that establish or improve systems of coordination between government entities. The report includes a series of proposals from the Department of Human Services (DHS) that redesign the adult abuse assessment process that are necessary for long-term reform. Included in them is a proposal to enhance a community’s capacity to provide a safety net of services, as well as formal and informal supports for vulnerable adults through partnerships among multiple local stakeholders.

Extra burden of psychosomatic complaints among adolescents suffering from chronic conditions.

OBJECTIVE:: To determine whether there are differences in health perception and health care use among adolescents with psychosomatic symptoms (PS), with chronic conditions (CCs), and with both conditions compared with healthy controls. METHODS:: By using the SMASH02 database, 4 groups were created: youths with PS but no CCs (N = 1010); youths with CCs but no PS (N = 497); youths with both psychosomatic symptoms and chronic conditions (PSCC, N = 213); and youths with neither PS nor CC (control, N = 5709). We used χ tests and analysis of variance to compare each variable between the 4 groups. In a second step, all health and health care use variables were included in a multinomial regression analysis controlling for significant (p < .05) background variables and using the control group as the reference. RESULTS:: Overall, PS and PSCC youths were significantly more likely to rate their health as poor, to be depressed, and to have consulted several times their primary health care provider or a mental health professional than their healthy peers. With the exception of being depressed, PSCC adolescents reported worse health perception and higher health care use than CC and PS. CONCLUSIONS:: Although PS youths do not define PS as a CC, it should be considered as one. Moreover, having PS represents an additional burden to chronically ill adolescents. Health professionals dealing with adolescents must be aware of the deleterious health effects that PS can have on adolescents and have this diagnosis in mind to better target the treatment and improve their management.

Low malathion concentrations influence metabolism in Chironomus sancticaroli (Diptera, Chironomidae) in acute and chronic toxicity tests

Low malathion concentrations influence metabolism in Chironomus sancticaroli (Diptera, Chironomidae) in acute and chronic toxicity tests. Organophosphate compounds are used in agro-systems, and in programs to control pathogen vectors. Because they are continuously applied, organophosphates often reach water sources and may have an impact on aquatic life. The effects of acute and chronic exposure to the organophosphate insecticide malathion on the midge Chironomus sancticaroli are evaluated. To that end, three biochemical biomarkers, acetylcholinesterase (AChE), alpha (EST-α) and beta (EST-β) esterase were used. Acute bioassays with five concentrations of malathion, and chronic bioassays with two concentrations of malathion were carried out. In the acute exposure test, AChE, EST-α and EST-β activities declined by 66, 40 and 37%, respectively, at 0.251 µg L-1 and more than 80% at 1.37, 1.96 and 2.51 µg L-1. In chronic exposure tests, AChE and EST-α activities declined by 28 and 15% at 0.251 µg L-1. Results of the present study show that low concentrations of malathion can influence larval metabolism, indicating high toxicity for Chironomus sancticaroli and environmental risk associated with the use of organophosphates.

Enfermagem e reinserção da pessoa portadora de doença mental institucionalizada na família

Com este trabalho científico pretendeu-se examinar o contributo da enfermagem na reinserção da pessoa portadora da doença mental institucionalizada na família. É um estudo exploratório descritivo de natureza qualitativa, direccionada às famílias das ppdm institucionalizadas no Centro de Apoio de Doentes Mentais de São Vicente. Neste sentido, participaram do estudo 5 famílias das respectivas ppdm institucionalizadas e o estudo decorreu nos domicílios das respectivas famílias. As informações foram colhidas através de uma entrevista semiestruturada e os dados tratados com base na análise de conteúdo. Os resultados apontam que existem um leque de factores que dificultam a reinserção, nomeadamente a carência da informação por parte dos familiares da ppdm e a consequente falta de envolvimento da família no seu tratamento, o impacto da sobrecarga de diversa ordem e a necessidade de um trabalho por parte dos cuidadores de saúde no sentido de auxiliarem e apoiarem estas famílias, com maior proximidade e de forma holística. Este trabalho trouxe um contributo a nível teórico no sentido de promover futuros trabalhos ligados a esta problemática e a necessidade de investir em trabalhos mais direccionadas às comunidades, sendo um ponto que precisa de ser trabalhado. Em termos práticos a pesquisa veio expor a necessidade de uma intervenção multidisciplinar em prol da reinserção da pessoa portadora da doença mental institucionalizada na família, tanto no sentido de promover a socialização e reduzir as consequências de uma institucionalização prolongada. Conclui-se, finalmente que existe uma necessidade de um trabalho de Enfermagem em Saúde Mental e Psiquiatria mais virada as famílias em suas próprias comunidades/residências, tanto de promoção a saúde e de prevenção em todos os níveis.

Nitric oxide mediates the blood pressure response to mental stress in humans.

OBJECTIVE: Nitric oxide (NO) regulates arterial pressure by modulating peripheral vascular tone and sympathetic vasoconstrictor outflow. NO synthesis is impaired in several major cardiovascular disease states. Loss of NO-induced vasodilator tone and restraint on sympathetic outflow could result in exaggerated pressor responses to mental stress. METHODS: We, therefore, compared the sympathetic (muscle sympathetic nerve activity) and haemodynamic responses to mental stress performed during saline infusion and systemic inhibition of NO-synthase by NG-monomethyl-L-arginine (L-NMMA) infusion. RESULTS: The major finding was that mental stress which during saline infusion increased sympathetic nerve activity by ~50 percent and mean arterial pressure by ~15 percent had no detectable sympathoexcitatory and pressor effect during L-NMMA infusion. These findings were not related to a generalised impairment of the haemodynamic and/or sympathetic responsiveness by L-NMMA, since the pressor and sympathetic nerve responses to immersion of the hand in ice water were preserved during L-NMMA infusion. CONCLUSION: Mental stress causes pressor and sympathoexcitatory effects in humans that are mediated by NO. These findings are consistent with the new concept that, in contrast to what has been generally assumed, under some circumstances, NO has a blood pressure raising action in vivo.

Correlates of frailty, prediction of functional decline and preventative approaches - selected results from the lausanne cohort 65+ (lc65+) study (Switzerland) (Lausanne) and the longitudinal urban cohort ageing study (Lucas) (Germany)

Overall introduction.- Longitudinal studies have been designed to investigate prospectively, from their beginning, the pathway leading from health to frailty and to disability. Knowledge about determinants of healthy ageing and health behaviour (resources) as well as risks of functional decline is required to propose appropriate preventative interventions. The functional status in older people is important considering clinical outcome in general, healthcare need and mortality. Part I.- Results and interventions from lucas (longitudinal urban cohort ageing study). Authors.- J. Anders, U. Dapp, L. Neumann, F. Pröfener, C. Minder, S. Golgert, A. Daubmann, K. Wegscheider,. W. von Renteln-Kruse Methods.- The LUCAS core project is a longitudinal cohort of urban community-dwelling people 60 years and older, recruited in 2000/2001. Further LUCAS projects are cross-sectional comparative and interventional studies (RCT). Results.- The emphasis will be on geriatric medical care in a population-based approach, discussing different forms of access, too. (Dapp et al. BMC Geriatrics 2012, 12:35; http://www.biomedcentral.com/1471-2318/12/35): - longitudinal data from the LUCAS urban cohort (n = 3.326) will be presented covering 10 years of observation, including the prediction of functional decline, need of nursing care, and mortality by using a self-filling screening tool; - interventions to prevent functional decline do focus on first (pre-clinical) signs of pre-frailty before entering the frailty-cascade ("Active Health Promotion in Old Age", "geriatric mobility centre") or disability ("home visits"). Conclusions.- The LUCAS research consortium was established to study particular aspects of functional competence, its changes with ageing, to detect pre-clinical signs of functional decline, and to address questions on how to maintain functional competence and to prevent adverse outcome in different settings. The multidimensional data base allows the exploration of several further questions. Gait performance was exmined by GAITRite®-System. Supported by the Federal Ministry for Education and Research (BMBF Funding No. 01ET1002A). Part II.- Selected results from the lausanne cohort 65+ (Lc65 + ) Study (Switzerland). Authors.- Prof Santos-Eggimann Brigitte, Dr Seematter-Bagnoud Laurence, Prof Büla Christophe, Dr Rochat Stéphane. Methods.- The Lc65+ cohort was launched in 2004 with the random selection of 3054 eligible individuals aged 65 to 70 (birth year 1934-1938) in the non-institutionalized population of Lausanne (Switzerland). Results.- Information is collected about life course social and health-related events, socio-economics, medical and psychosocial dimensions, lifestyle habits, limitations in activities of daily living, mobility impairments, and falls. Gait performance are objectively measured using body-fixed sensors. Frailty is assessed using Fried's frailty phenotype. Follow-up consists in annual self-completed questionnaires, as well as physical examination and physical and mental performance tests every three years. - Lausanne cohort 65+ (Lc65 + ): design and longitudinal outcomes. The baseline data collection was completed among 1422 participants in 2004-2005 through self-completed questionnaires, face-to-face interviews, physical examination and tests of mental and physical performances. Information about institutionalization, self-reported health services utilization, and death is also assessed. An additional random sample (n = 1525) of 65-70 years old subjects was recruited in 2009 (birth year 1939-1943). - lecture no 4: alcohol intake and gait parameters: prevalent and longitudinal association in the Lc65+ study. The association between alcohol intake and gait performance was investigated.
