Los Pioneros del cooperativismo agrario de crédito español (1880-1920)

En las dos últimas décadas del siglo XIX en España el cooperativismo de crédito orientado hacia los pequeños productores agrícolas estuvo bastante ligado a las corrientes del “Regeneracionismo conservador” y el catolicismo social. Hemos estudiado las aportaciones de dos autores: Joaquín Díaz de Rábago y Nicolás Fontes. Díaz de Rábago contó con una fuerte formación teórica y colaboró en la redacción de un proyecto de ley sobre cooperativas, pero a pesar de su influencia no consiguió potenciar ninguna actividad concreta. Nicolás Fontes representa al hombre “práctico”. Sus circunstancias personales, era un importante terrateniente, lo animaron a poner en práctica un sistema de crédito destinado a ayudar a los pequeños arrendatarios. El modelo que puso en práctica se inspiraba en el Raiffeisen System, el mismo que defendía por Rábago. El desconocimiento mutuo de sus actuaciones invita a reflexionar sobre las limitaciones en la difusión del cooperativismo agrícola de crédito en España.

Contribuição para o conhecimento de alguns cestódeos do gênero Raillietina Fuhrmann, 1920, (Cestoda-Davaineidae), parasitos de columbiformes

Contribuindo para o conhecimento de alguns cestódeos do gênero Raillietina Fuhrmann, 1920, parasitos de Columbiformes, são estudadas aqui duas espécies encontradas em intestino delgado de columba livia dom. L. 1758. Uma delas, Raillietina (Raillietina) allomyodes (Kotlan, 1921), originalmente descrita da Nova Guiné, é agora assinalada pela primeira vez no Brasil, em novo hospedeiro. A outra, Raillietina (Fuhrmannetta) crassula (Rudolphi, 1819) apesar de ter sido descrita de material do Brasil e África, não tem uma descrição detalhada.

Studies on Trypanosoma rangeli Tejera 1920. IV - A reconsideration of its systematic position

The systematic positon of Trypanosoma rangeli is reconsidered and the creation of a new subgenus. Tejeraia, is proposed to remove this trypanosome from the subgenus Herptosoma of the section Stercoraria. The characteristics described for the proposed subgenus indicate that it must be located in the section Salivaria rather than in the Stercoraria. The evidence supporting this proposition is discussed in the text.

Studies on Trypanosoma rangeli Tejera, 1920: V - Developmental pattern in the alimentary canal of Rhodnius prolixus

The morphological sequence of Trypanosoma rangeli development in the alimentary canal of Rhodnius prolixus, is described, with observation made in dissected guts from 6 hours to 45 days post-infection. No metacyclic-forms are produced in the digestive tract at any time, and transmission by the contaminative route must be considered atypical. Amastigotes appear to be an essential stage in the development of T. rangeli in the gut of R. prolixus. The epidemiological importance of the developmental pattern of T. rangeli in the vector´s gut is discussed, and its usefulness for aging infection is considered.

Studies on Trypanosoma rangeli Tejera 1920: VI. Developmental pattern in the haemolymph of Rhodnius prolixus

The morphological sequence of Trypanosoma rangeli development in the body cavity of Rhodnius prolixus is described. The metacyclic trypanosome is the product of successive division and transformation during the intra and extracellular development in the haemocoele. The significance of the early invasion of T. rangeli into the haemolymph is discussed. The epidemiological importance of the developmental pattern of T. rangeli in the vectors haemolymph and the host-response to the parasite are considered.

Studies on Trypanosoma rangeli Tejera 1920. VII - Its effect on the survival of infected triatomine bugs

The pathological effects of Trypanosoma rangeli on Rhodnius prolixus and R. robustus, and the relation of mortality to infection, were studied under laboratory conditions. Frequent observations revealed that when the first instar nymphs of R. prolixus and R. robustus were infected with T. rangeli, survival of the bugs during the stages of development to the adult stage decreased. This decrease was statistically significant when compared with uninfected control-bugs, indicating that T. rangeli is pathogenic for both species of triatomine. In R. prolixus the most affected nymphal stages were the first, second and fifth instars, where a higher mortality was also observed. In R. robustus a progressive increase of the mortality from the first to fifth instars, was observed. The pathogenicity of T. rangeli as measured by overall mortality was the same in R. prolixus and R. robustus. The possible pathogenic mechanism of T. rangeli in triatomine-bugs and its epidemiological implications, are discussed.

Estudios sobre Trypanosoma rangeli Tejera, 1920: VIII. Respuesta a las reinfecciones en dos mamíferos

Bajo condiciones experimentales se estudia el curso de la infección primaria y la respuesta a las reinfecciones por Trypanosoma rangeli en ratones albinos y Didelphis marsupialis. Durante el curso de la infección primaria en ratones, se observa una parasitemia relativamente baja y de corta duración. Los mismos muestran durante la primera reinfección una parasitemia escasa de cuatro días de duración, siendo resistentes a las sucesivas reinfecciones con T. rangeli. Los ejemplares de D. marsupialis exhiben una parasitemia de más larga duración, pero con un nivel de parásitos sanguícolas mucho menor que el detectado en el modelo ratón, siendo la respuesta a las reinfecciones similar a la observada en ratones. Se detectan anticuerpos hemaglutinantes en los sueros inmunes de ratones y Didelphis marsupialis, sometidos a la reinfección por T. rangeli. Se especula sobre la posible acción sinérgica de una respuesta inmune en el sitio de deposición en contra de las formas metacíclicas de T. rangeli y la acción de anticuerpos circulantes en contra de las formas sanguícolas, para explicar la resistencia de ambos modelos a las reinfecciones por T. rangeli.

Evaluation épidémiologique du programme genevois de dépistage du cancer du sein : 2007-2011

A l'instar de nombreux pays industrialisés, le cancer du sein est à Genève le cancer le plus fréquent (environ 460 cas par an) et la première cause de décès chez les femmes entre 45 et 55 ans. Depuis mars 1999, le Programme genevois de dépistage du cancer du sein a pour missions de promouvoir, d'organiser et de mener une action de prévention auprès de la population féminine du canton âgée de 50 à 69 ans. Ce rapport décrit l'évolution de 15 ans d'activité de dépistage (chapitre 2) et analyse l'utilisation (chapitre 3), la qualité (chapitre 4) et l'efficacité (chapitre 5) du programme genevois entre 2007 et 2011. Couvrant 86'720 mammographies et près de 37'000 femmes, ce rapport s'intéresse aussi, au-delà des indicateurs usuels de performance, à mieux estimer certains effets indésirables comme les résultats faussement positifs ou les cancers survenant entre 2 examens de dépistage (dits cancers d'intervalle).

Studies on Trypanosoma rangeli Tejera, 1920: IX. Course of infection in different stages of Rhodnius prolixus

Frequent individual observations od different stages of Rhodnius prolixus exposed to Trypanosoma rangeli, revealed a higher susceptibility to infection in the bugs exposed during the two first instars. The mortality rate in infected bugs was significantly higher than in controls, indicating that the parasite was responsible for the majority of deaths. An analysis of the mortality distribution, per instar, is presented. Statistical analysis of deaths among the different infected instars, showed that T. rangeli produces its pathological effect in any stage of R. prolixus independently of its susceptibility to the parasite. The survival to adult decreased in all the infected instar bugs. A significant longer time to reach the adult stage was observed in the infected bugs when compared with controls, excepting for specimens exposed in the third instar. The epidemiological significance of the present results is discussed.

Programme cantonal Diabète: bilan de la première phase du programme (2010-2011) et construction d'une théorie d'action.

Le Programme cantonal diabète (PCD) du canton de Vaud a pour objectifs de réduire durablement l'impact du diabète sur la population vaudoise. Il a été élaboré à l'initiative du Service de la santé publique du canton de Vaud et la stratégie du programme a été construite sur la base des propositions de plusieurs groupes de travail. Ce programme inclut divers projets complémentaires qui ont été progressivement mis sur pied à partir de 2010. 2012 marque la fin de la première phase du programme et une évaluation-bilan du programme est demandée. Cette évaluation-bilan fait suite à une première phase de travaux qui ont consisté en une évaluation de l'évaluabilité du programme. Les résultats de cette première phase ont été délivrés en décembre 2011 au groupe de pilotage et consignés dans un rapport en février 2012. L'IUMSP propose donc pour 2012 des travaux en continuité de ce qui a été fait en 2011 et qui vont dans le sens d'un bilan critique et de propositions pour un système de monitoring à long terme du programme, comportant des indicateurs d'activité (à harmoniser lorsque c'est possible dans des projets similaires), des indicateurs de couverture et de résultats.

Development of the First Disease Activity Index for Eosinophilic Esophagitis: Update on the EEsAI in 2011

Background a nd Aims: T he international E EsAI study g roupis currently developing the first activity index (EEsAI) specificfor Eosinophilic Esophagitis (EoE). Goal: To develop, evaluateand validate the EEsAI.Methods: T he d evelopment comprises three phases: 1.Selection of candidate items; 2. Evaluation of the activity indexin a f irst patient cohort; and 3. V alidation in a s econd EoEpatient cohort. Focus group interviews with patients were usedin p hase 1 to generate p atient r eported outcomes ( PRO)according to guidelines o f regulatory authorities ( FDA andEMA), whereas the section of biologic items was developed byDelphi r ounds of i nternational E oE experts from E urope andNorth America.Results: The EEsAI has a modular composition to assess thefollowing components o f EoE activity: p atient reportedoutcomes, endoscopic activity, histologic activity, laboratoryactivity, a nd quality of life. D efinitions f or all aspects o fendoscopic and histologic appearance were established byconsensus rounds among EoE experts. Symptom assessmenttools were created that take into account d ifferent foodconsistencies as w ell as f ood avoidance and specificprocessing strategies. T he EEsAI is evaluated in a c ohort ofadult EoE patients since March 2011.Conclusions: After successful validation, the EEsAI will allowto standardize outcome assessment in E oE t rials which w illlikely lead to its wide applicability.
