Trajectòries de la psicomotricitat: la vivència corporal com a accés a la pròpia identitat i a la representació mental

En aquest article es realitza una descripció històrica i una crítica de les diferents tendències que ha seguit l'estudi i desenvolupament de les teoríes psicomotrius en la infància, així com una proposta que enfoca la psicomotricitat des d'un plantejament bàsicament preventiu i educador.

Utilité de la recherche des autoanticorps dans la pratique quotidienne [Use of autoantibodies in clinical practice]

Autoantibodies are frequently determined in unclear clinical situations and in the context of an inflammatory syndrome. The aim of this article is not to review all autoantibodies in details, but to discuss those used in clinical practice by describing their methods of detection and interpretation. Thus we will focus on antinuclear antibodies (ANA), which are typically associated with connective tissue diseases, as well as anti-neutrophil cytoplasmic antibodies (ANCA), which are useful in the diagnosis of ANCA-associated vasculitides. Due to its high sensitivity indirect immunofluorescence is used as a screening test; when positive, ELISA is performed to search for antibodies more specifically associated with certain auto-immune diseases.

Small farmers of the Florida Province (Bolivia) : Reciprocity in Practice

Peasant societies are often seen by neoliberal or Marxist theorists as passive subjects of political-economic transformations occurring at a higher level, only surviving through acculturation to market requirements. By analyzing agricultural work organization in highland communities and a local system of water management called Acuerdos Reciprocos por el Agua (Reciprocal Agreements for Water), developed in 2003 by the Natura Bolivia foundation in Florida Province in Bolivia, we show that, contrary to this perception, traditional reciprocal norms still play an essential role in decision making. This suggests the agency of rural societies and the resilience of traditional reciprocity-based norms in mountain regions.

La pratique infirmière avancée [Advanced practice nursing].

Dans les sociétés contemporaines axées sur le savoir, plus grande sera la proportion de leur population détentrice d'une formation supérieure et engagée en recherche, plus avancé sera leur développement économique et social.1,2 Par contre, dans ces sociétés, le vieillissement de la population, l'importance ccordée aux soins de santé axés sur les maladies chroniques et les coûts financiers de ceux-ci exercent une forte pression sur les systèmes de santé. Les nterventions doivent donc être les plus efficaces possible, avec un rapport coût/efficacité optimal. Cela requiert que les infirmières soient capables d'oeuvrer en pratique avancée, c'est-à-dire capables de développer, implémenter et évaluer des approches cliniques infirmières basées sur des preuves, de tester de nouvelles interventions potentiellement plus efficientes et de promouvoir un programme de recherche portant explicitement sur l'amélioration de la qualité et sécurité des soins en contexte d'interdisciplinarité.

Composição corporal e exigências nutricionais em magnésio, potássio e sódio de cordeiros Santa Inês

O trabalho objetivou determinar a composição corporal de cordeiros Santa Inês e estimar suas exigências de magnésio, potássio e sódio, para ganho de peso. Foram conduzidos dois experimentos com 18 cordeiros machos em cada um, com peso médio inicial de 25 e 15 kg no primeiro e no segundo experimentos, respectivamente. Em cada experimento, seis animais foram abatidos, para determinação das quantidades de cada mineral retido no corpo, servindo como animais-referência para a técnica do abate comparativo. Os doze animais remanescentes em cada experimento foram divididos em dois grupos: seis animais receberam alimentação ad libitum e seis receberam alimentação restrita. Os cordeiros do grupo ad libitum e restrito foram abatidos quando os do grupo ad libitum atingiram 35 e 25 kg de peso vivo no primeiro e segundo experimentos, respectivamente. A composição corporal em Ca, P, Mg, K e Na foi estimada a partir de equações de regressão do logaritmo da quantidade desses minerais presentes no corpo vazio dos animais, em razão do peso corporal vazio. As exigências líquidas desses minerais por kg de ganho de peso vivo, obtidas a partir da derivação das equações de predição da composição corporal foram: 0,47 e 0,41 g de Mg, 2,32 e 2,05 g de K e 1,33 e 0,55 g de Na, respectivamente, em animais com 15 e 35 kg.

Composição corporal e exigências nutricionais de cálcio e fósforo de cordeiros Santa Inês em crescimento

Dois experimentos foram conduzidos com o objetivo de determinar a composição corporal e estimar as exigências de Ca e P, para ganho em peso, de cordeiros Santa Inês em crescimento. Em cada experimento foram usados 18 animais com 25 a 35 kg de peso vivo (PV), no primeiro, e com 15 a 25 kg no segundo experimento. Seis animais foram abatidos no início de cada experimento para avaliar o conteúdo de Ca e P corporal, servindo como animais referência para o método do abate comparativo, seis animais receberam alimentação ad libitum e seis, alimentação restrita. As exigências líquidas de Ca e P para o ganho em peso foram estimadas a partir da derivação de equações de regressão do logaritmo da quantidade desses minerais presentes no corpo vazio, em função do peso do corpo vazio. As exigências líquidas por quilo de ganho de PV para animais com 15, 25 e 35 kg de PV foram, respectivamente: 11,63, 10,52 e 9,82 g de Ca e 5,82, 4,99 e 4,28 g de P.

Traitements de fer: preuves de t'efficacité et bonne pratique clinique [Iron therapy: proof of efficacy and good clinical practice].

Efficacy of iron therapy, whether oral or intravenous, on biological markers of body iron stores is well recognized in medical literature, but current studies are heterogeneous, of sometimes dubious quality, and rarely address clinical outcomes. Precise practical guidelines appear available only for indications related to kidney disease. First-line intravenous use is reserved for situations comprising chronic renal failure, or patients presenting with malabsorption syndromes such as in inflammatory bowel disease. In all other situations, because of the non-negligible risk of hypersensitivity reactions, intravenous iron use is considered justified only in clinically sustained indications, for patients in whom oral administration of iron is unsatisfactory or impossible.

EASL Clinical Practice Guidelines: Wilson's disease.

This Clinical Practice Guideline (CPG) has been developed to assist physicians and other healthcare providers in the diagnosis and management of patients with Wilson's disease. The goal is to describe a number of generally accepted approaches for diagnosis, prevention, and treatment of Wilson's disease. Recommendations are based on a systematic literature review in the Medline (PubMed version), Embase (Dialog version), and the Cochrane Library databases using entries from 1966 to 2011. The Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) system used in other EASL CPGs was used and set against the somewhat different grading system used in the AASLD guidelines (Table 1A and B). Unfortunately, there is not a single randomized controlled trial conducted in Wilson's disease which has an optimal design. Thus, it is impossible to assign a high or even a moderate quality of evidence to any of the questions dealt with in these guidelines. The evaluation is mostly based on large case series which have been reported within the last decades.

Nature conservation efforts by forest owners : intentions and practice in a Swedish case study

Abstract

Prescription du monitoring pratique médicate: de l'empirisme eclairé aux stratégies rationnelles [Prescribing monitoring in clinical practice: from enlightened empiricism to rational strategies].

Monitoring of a medical condition is the periodic measurement of one or several physiological or biological variables to detect a signal regarding its clinical progression or its response to treatment. We distinguish different medical situations between diagnostic, clinical and therapeutic process to apply monitoring. Many clinical, variables can be used for monitoring, once their intrinsic properties (normal range, critical difference, kinetics, reactivity) and external validity (pathophysiological importance, predictive power for clinical outcomes) are established. A formal conceptualization of monitoring is being developed and should support the rational development of monitoring strategies and their validation through appropriate clinical trials.

The social disembedding of business theory and practice. A (neo-)institutional analysis of the homo economicus and corporate social responsibility, and the inherent responsibility of business scholars

Aim Structure of the Thesis In the first article, I focus on the context in which the Homo Economicus was constructed - i.e., the conception of economic actors as fully rational, informed, egocentric, and profit-maximizing. I argue that the Homo Economicus theory was developed in a specific societal context with specific (partly tacit) values and norms. These norms have implicitly influenced the behavior of economic actors and have framed the interpretation of the Homo Economicus. Different factors however have weakened this implicit influence of the broader societal values and norms on economic actors. The result is an unbridled interpretation and application of the values and norms of the Homo Economicus in the business environment, and perhaps also in the broader society. In the second article, I show that the morality of many economic actors relies on isomorphism, i.e., the attempt to fit into the group by adopting the moral norms surrounding them. In consequence, if the norms prevailing in a specific group or context (such as a specific region or a specific industry) change, it can be expected that actors with an 'isomorphism morality' will also adapt their ethical thinking and their behavior -for the 'better' or for the 'worse'. The article further describes the process through which corporations could emancipate from the ethical norms prevailing in the broader society, and therefore develop an institution with specific norms and values. These norms mainly rely on mainstream business theories praising the economic actor's self-interest and neglecting moral reasoning. Moreover, because of isomorphism morality, many economic actors have changed their perception of ethics, and have abandoned the values prevailing in the broader society in order to adopt those of the economic theory. Finally, isomorphism morality also implies that these economic actors will change their morality again if the institutional context changes. The third article highlights the role and responsibility of business scholars in promoting a systematic reflection and self-critique of the business system and develops alternative models to fill the moral void of the business institution and its inherent legitimacy crisis. Indeed, the current business institution relies on assumptions such as scientific neutrality and specialization, which seem at least partly challenged by two factors. First, self-fulfilling prophecy provides scholars with an important (even if sometimes undesired) normative influence over practical life. Second, the increasing complexity of today's (socio-political) world and interactions between the different elements constituting our society question the strong specialization of science. For instance, economic theories are not unrelated to psychology or sociology, and economic actors influence socio-political structures and processes, e.g., through lobbying (Dobbs, 2006; Rondinelli, 2002), or through marketing which changes not only the way we consume, but more generally tries to instill a specific lifestyle (Cova, 2004; M. K. Hogg & Michell, 1996; McCracken, 1988; Muniz & O'Guinn, 2001). In consequence, business scholars are key actors in shaping both tomorrow's economic world and its broader context. A greater awareness of this influence might be a first step toward an increased feeling of civic responsibility and accountability for the models and theories developed or taught in business schools.

Efeito do peso corporal na fecundidade e na longevidade do percevejo predador Podisus rostralis

Considerando a importância dos percevejos predadores como agentes de controle biológico e a necessidade de se otimizar sua produção massal, realizou-se o presente trabalho para avaliar a influência do peso corporal sobre a sobrevivência e a reprodução de fêmeas de Podisus rostralis (Stål) (Hemiptera: Pentatomidae). Os tratamentos foram constituídos por fêmeas desse predador com peso médio de: 39,5 mg, 45,5 mg, 51,5 mg, 57,5 mg e 63,5 mg. O período de preoviposição foi menor nas fêmeas mais pesadas, enquanto o número de ovos e de ninfas por dia apresentou relação linear positiva com o peso das fêmeas de P. rostralis. A longevidade das fêmeas desse predador foi semelhante entre tratamentos, porém não apresentou tendência de variação em razão do seu peso corporal. Como o objetivo de uma criação massal é produzir o maior número possível de ninfas por dia, recomenda-se o uso de fêmeas de P. rostralis com peso acima de 60,0 mg.

From evidence to clinical practice: effective implementation of therapeutic hypothermia to improve patient outcome after cardiac arrest.

OBJECTIVES: Therapeutic hypothermia has been recommended for postcardiac arrest coma due to ventricular fibrillation. However, no studies have evaluated whether therapeutic hypothermia could be effectively implemented in intensive care practice and whether it would improve the outcome of all comatose patients with cardiac arrest, including those with shock or with cardiac arrest due to nonventricular fibrillation rhythms. DESIGN: Retrospective study. SETTING: Fourteen-bed medical intensive care unit in a university hospital. PATIENTS: Patients were 109 comatose patients with out-of-hospital cardiac arrest due to ventricular fibrillation and nonventricular fibrillation rhythms (asystole/pulseless electrical activity). INTERVENTIONS: We analyzed 55 consecutive patients (June 2002 to December 2004) treated with therapeutic hypothermia (to a central target temperature of 33 degrees C, using external cooling). Fifty-four consecutive patients (June 1999 to May 2002) treated with standard resuscitation served as controls. Efficacy, safety, and outcome at hospital discharge were assessed. Good outcome was defined as Glasgow-Pittsburgh Cerebral Performance category 1 or 2. MEASUREMENTS AND MAIN RESULTS: In patients treated with therapeutic hypothermia, the median time to reach the target temperature was 5 hrs, with a progressive reduction over the 18 months of data collection. Therapeutic hypothermia had a major positive impact on the outcome of patients with cardiac arrest due to ventricular fibrillation (good outcome in 24 of 43 patients [55.8%] of the therapeutic hypothermia group vs. 11 of 43 patients [25.6%] of the standard resuscitation group, p = .004). The benefit of therapeutic hypothermia was also maintained in patients with shock (good outcome in five of 17 patients of the therapeutic hypothermia group vs. zero of 14 of the standard resuscitation group, p = .027). The outcome after cardiac arrest due to nonventricular fibrillation rhythms was poor and did not differ significantly between the two groups. Therapeutic hypothermia was of particular benefit in patients with short duration of cardiac arrest (<30 mins). CONCLUSIONS: Therapeutic hypothermia for the treatment of postcardiac arrest coma can be successfully implemented in intensive care practice with a major benefit on patient outcome, which appeared to be related to the type and the duration of initial cardiac arrest and seemed maintained in patients with shock.
