ABSTRACT

Abstract The Toltén river is located in the 137 years old Araucania region, Chile (38° S), and is characterized by low alterations through human interference due agriculture and towns in its surrounding basin, the presence of native fishes and salmonids, and by its lake effluent regime originated from Villarrica lake. The aim of the present study was to make a review of ecological role of the benthic inland water macroinvertebrates as preys for native fishes of the River Toltén, in order to understand their importance in the ecosystem of the river. The literature revealed that the main prey for native fishes are Chironomidae larvae, nevertheless there are not specific reports for Tolten river. The exposed results are similar with similar native species for Patagonia, and these native species would have prey for introduced salmonids, or these species would have prey competition with introduced salmonids in according to the literature descriptions for Argentinean and Chilean Patagonia.


Resumo O rio Toltén está localizado na região da Araucanía, com 137 anos de idade, Chile (38° S), e é caracterizado por baixas alterações por interferência humana devido à agricultura e cidades da bacia circundante, pela presença de salmonídeos e pelo regime de efluentes dos lagos. do lago Villarrica. O objetivo do presente estudo foi fazer uma revisão do papel ecológico dos macroinvertebrados bentônicos de águas interiores do rio Toltén, a fim de entender sua importância no ecossistema do rio. A literatura revelou que as principais presas de peixes nativos são as larvas de Chironomidae, no entanto, não há relatos específicos para o rio Tolten. Os resultados expostos são semelhantes com espécies nativas semelhantes para a Patagônia, e essas espécies nativas teriam presa por salmonídeos introduzidos, ou essas espécies teriam competição de presas com salmonídeos introduzidos de acordo com as descrições da literatura para a Patagônia Argentina e Chilena.

ABSTRACT

Abstract The management and use of native species under laboratory conditions is the main difficult for species proposal for its use in bioassays. The present study showed the results about management under controlled conditions of Paratanytarsus grimmii (Diptera: Chironomidae), that is a parthenogenetic species with wide geographical distribution. It obtained its eggs from a pre Andean river from Araucania region (39° S), and it determined the conditions for larval rearing under artificial food, adults getting (manipulation), eggs (hatching sincronization) and larvae getting after hatching. The P.grimmii life cycle had larvae that late 23 days in get the pupa stage (stage I to IV), the adult within the next 48 hours deposits the eggs that hatched at 72 hours. It stablished laboratory conditions: incubation room temperature, water pH, and artificial feeding, photoperiod and larvae and eggs management techniques. In according to obtained results it managed all life cycles under laboratory conditions that can propose the use of this species as potential biological material for toxicity bioassays.


Resumo O manejo e o uso de espécies nativas em condições de laboratório são as principais dificuldades para a proposta de uso de espécies em bioensaios. O presente estudo mostrou os resultados acerca do manejo sob condições controladas de Paratanytarsus grimmii (Diptera: Chironomidae), espécie partenogenética com ampla distribuição geográfica. Foram obtidos seus ovos de um rio pré-andino da região de Araucanía (39º S) e determinadas as condições para criação de larvas sob alimentação artificial, obtenção de adultos (manipulação), de ovos (sincronização de eclosão) e de larvas após a eclosão. O ciclo de vida de P. grimmii teve larvas que, ao final dos 23 dias, atingiram o estágio de pupa (estágio I a IV). O adulto depositou nas 48 horas seguintes os ovos que eclodiram às 72 horas. Foram estabelecidas condições laboratoriais: temperatura da sala de incubação, pH da água e alimentação artificial, fotoperíodo e técnicas de manejo de larvas e ovos. De acordo com os resultados obtidos, foram gerenciados todos os ciclos de vida em condições de laboratório que podem propor o uso dessa espécie como material biológico potencial para bioensaios de toxicidade.

ABSTRACT

Abstract Studies in Salvelinus alpinus, Arctic charr, indicate that it has a low capacity to hyposmorregulatory or adaption to sea in winter periods in Arctic waters. The investigation finds to determinate the rank optimum of salinity to can cultivate this species at Chile. The weight adequate was determined to join on the sea by analysis of gill Na+, K+-ATPase activity, that it was found between the ranks 80-130 g, with 14.5 U/mg. It underwent evaluation of fish growth of 72 g salinities from 0 (control), 18, 25 and 33 g/L (sea water) for 94 days. The results indicate that the largest increases were obtained in brackish water. T18 g/L and T25 g/L achieved growth of 25% and 19% on day 94 and term sampling respectively. It is important to mention that the 8% that survived in seawater introduced percentages growth 16.6% equivalent to brackish water and control. These results suggest that Salvelinus alpinus can grow in seawater, with levels of Na+, K+-ATPase similar to those submitted by Salmo salar with a weight not less than 80 g.


Resumo Estudos em Salvelinus alpinus, Charr Ártico, indicam que tem baixa capacidade de hiposmorregulação ou adaptação ao mar em períodos de inverno nas águas do Ártico. A investigação determina o melhor nível de salinidade para cultivar esta espécie no Chile. Determinou-se o peso adequado para se unir ao mar pela análise da atividade da Na +, K + -ATPase das brânquias, que foi encontrada entre as faixas de 80 a 130 g, com 14,5 U/mg. Foi avaliado o crescimento de 72 g salinidades de 0 (controle), 18, 25 e 33 g/L (água do mar) por 94 dias. Os resultados indicam que os maiores aumentos foram obtidos em água salobra. T18 g/L e T25 g/L alcançaram crescimento de 25% e 19% no dia 94 e amostragem a termo, respectivamente. É importante mencionar que os 8% que sobreviveram na água do mar apresentaram percentuais de crescimento de 16,6% equivalentes a água salobra e controle. Estes resultados sugerem que o Salvelinus alpinus pode crescer em água do mar, com níveis de Na +, K + -ATPase semelhantes aos apresentados por Salmo salar com um peso não inferior a 80 g.

ABSTRACT

Abstract The Cautin river is located in the 137 years old Araucania region, Chile (38°S), and is characterized by alterations through human interference due agriculture and towns in its surrounding basin, the presence of salmonids, and by its mixed regime, originated from snow melting in summer and rains in winter. The aim of the present study was to make a review of the inventory and ecological role of the benthic inland water macroinvertebrates of the River Cautin, in order to understand their importance in the ecosystem of the river. The fauna of this river includes a fauna composed of endemic and introduced fish, which has, however, been only poorly studied until now. The literature revealed the presence of abundant populations of Diptera, Trichoptera and Ephemeroptera larval stages, and few crustaceans specifically amphipods and freshwater crabs along the river's course. Many of these macroinvertebrates are prey for both introduced salmonids and native fishes. Similar results have been reported for other southern Argentinean and Chilean Patagonian rivers.


Resumo O rio Cautin está localizado na região de Araucania, no Chile (38°S), é caracterizado por alterações através da interferência humana devido à agricultura e as cidades da bacia circundante, a presença de salmonídeos e pelo seu regime misto, originado pela queda de neve verão e chuvas no inverno. O objetivo do presente estudo foi fazer uma revisão do papel ecológico dos macroinvertebrados bentônicos das águas interiores do rio Cautin, para entender sua importância no ecossistema do rio. A fauna deste rio inclui uma fauna composta de espécies de peixes endêmicos e introduzidos, que, no entanto, tem sido mal estudada até agora. A literatura revelou a presença de abundantes populações de estádios de larvas Diptera, Trichoptera e Ephemeroptera, e poucos crustáceos especificamente anfípodes e caranguejos de água doce ao longo do curso do rio. Muitos desses macroinvertebrados são presas tanto para salmonídeos introduzidos quanto para peixes nativos. Resultados semelhantes foram relatados para outros rios sul da Patagônia Chilena e Argentina.

ABSTRACT

Abstract Deionized ammonium (NH3) acute toxicity (LC50-96h) in Patagonian blenny juveniles (Eleginops maclovinus) was assessed. Concentrations of deionized ammonium in salt water were prepared by using 24.09 ± 2.1 g ammonium chloride (NH4Cl). Fish were exposed in triplicates to different ammonium concentrations: 0.05; 0.094; 0.175; 0.325 and 0.605 mg NH3 L-1. Additionally, a control group was included. Experimental fish were kept at a photoperiod of 16:8h. Average temperatures were 16.24 ± 1.40 °C. Oxygen concentration was 7.16 ± 0.40 mg L -1. Water pH was 7.89 ± 0.2. LC50-96 h, was estimated by using Probit statistical method (95% intervals) using EPA software (1993). Juveniles of E. maclovinus showed a LC50-96h of 0.413mg NH3 L-1 value, different from most marine species. This study presents the first record of ammonium toxicity in marine species of Chile.

ABSTRACT

Abstract The present study assessed the percentage of survival and metamorphosis of larval stages of Caligus rogercresseyi (Boxshall and Bravo, 2000) nauplius I, nauplius II to and nauplius II to copepodite, conducting bioassays in triplicate with 50 larvae each, nauplius I or nauplius II, at temperature of 12 °C, 15 °C and 18 °C; salinity 20, 23, 25, 2729, 31, 33 and 35 g/L and oxygen saturation with ranges between 30-60%, 90-100% and 190 - 200%. Bioassays were performed in station Quillaipe of Fundación Chile, Puerto Montt, Chile. It is concluded that the temperature is inversely proportional to the time of metamorphosis and survival of the larvae of Caligus rogercresseyi . In salinity is observed that increased this, greater is the percentage of survival and metamorphosis is faster, while the larvae do not survive less than 20g/L. Oxygen saturation ranges indicate that the larvae do not survive at saturations between 30-60%, and it had no differences between 90-100% saturation and 190-200%.


Resumo O presente estudo avaliou a percentagem de sobrevivência e metamorfose dos estádios larvais de Caligus rogercresseyi (Boxshall and Bravo, 2000) nauplio I, nauplio II ae nauplio II a copepodita, realizando bioensaios em triplicado com 50 larvas cada, nauplio I ou nauplio II, À temperatura de 12 °C, 15 °C e 18 °C; Salinidade 20, 23, 25, 2729, 31, 33 e 35 g / L e saturação de oxigénio com variações entre 30-60%, 90-100% e 190-200%. Os bioensaios foram realizados na estação Quillaipe da Fundação Chile, Puerto Montt, Chile. Conclui - se que a temperatura é inversamente proporcional ao tempo de metamorfose e sobrevivência das larvas de Caligus rogercresseyi. Na salinidade observa-se que aumentou esta, maior é a percentagem de sobrevivência e metamorfose é mais rápida, enquanto as larvas não sobrevivem menos de 20g / L. Os intervalos de saturação de oxigénio indicam que as larvas não sobrevivem a saturações entre 30-60% e não têm diferenças entre 90-100% de saturação e 190-200%.

ABSTRACT

Al revisar la literatura nacional chilena no se vislumbra claramente cuál es el rol que debe cumplir el fonoaudiólogo en el ámbito educativo, aceptando que este sector tiene características particulares que implican otros desafíos además de la rehabilitación de alteraciones asociadas al lenguaje, la comunicación y/o la deglución. El presente estudio tiene como objetivos establecerla relación existente entre los años de experiencia del profesional fonoaudiólogo(a) en el sector educativo y su nivel de desempeño profesional y establecerla relación entre el sector de trabajo (educación especial, proyectos de integración y subvención escolar preferencial)y el desempeño profesional reportado por los especialistas en cada uno de ellos. El estudio utilizó un enfoque cuantitativo y un diseño no experimental descriptivo correlacional de corte transversal. Se aplicó el protocolo Autorreflexión del desempeño profesional del fonoaudiólogo en educación a 59 fonoaudiólogos(as). Los resultados indican que los fonoaudiólogos(as) reportan fortaleza en funciones de identificación, evaluación, intervención y gestión, declarando un menor desarrollo en ámbitos de prevención, conocimiento de la cultura escolar e investigación; no existe una relación significativa entre el nivel de desempeño declarado por los profesionales y los años de experiencia, así como tampoco entre el ámbito de trabajo del fonoaudiólogo(a)en educación y su rendimiento profesional. Se discute el rol educativo nacional desde una perspectiva internacional. Como conclusión se destaca la necesidad de iniciar una autorreflexión como gremio que permita retroalimentar a la academia y al propio sector educativo, facilitando la descripción y delimitación de la práctica fonoaudiológica en este ámbito...


The Chilean national literatura does not clearly show the role that the speech and language therapist has to accomplish in education, accepting that this area has specific characteristics which go beyond the intervention of language, communication or swallowing impairments. This study aims to establish the relation between years of professional experience as speech and language therapist in education with the standard of professional performance; and to establish the relation between such areas as special education, integration programs and preferential school subsidy with the professional performance reported by specialists working in each one of them. The study adopted a quantitative approach, with a non-experimental descriptive correlational and cross-sectional design. The protocol Self-reflection of the professional practice of the speech and language therapist in education was applied to 59speech and language therapists. The results showed that speech and language therapists stated strength in functions of identification, assessment, intervention and management. At the same time they declared less development in areas of prevention, school culture knowledge and research. There is no significant relation between the standards of performance declared by the professionals and the years of experience, or between the work area in education and professional performance. The national educational role is discussed from an international perspective. In conclusion, it is highlighted the need to initiate a self-reflection as a professional union allowing to provide feedback to the academy and to the educational area. This would also facilitate the description of the speech and language therapy practice in the educational area...

ABSTRACT

Obejtivos: Analizar los problemas de la política de focalización y las caracteristicas de la toma de decisiones para asignar subsidios en salud a la población de los niveles 3 y 4 del SISBEN de cuatro localidades de bogotá, buscando aportar elementos de juicio para transformar los procesos de formulación de políticas y corregir sus defectos en materia de marginalización y exclusión. Metodos: Se asumió un enfoque metodológico crítico, participativo y pluralista que combinó múltiples métodos y técnicas de investigación desde una perspectiva sistémica y pos-estructuralista. Se realizaron cuatro subproyectos. Se analizó la política de focalización de subsidios en Colombia con base en el análisis del discurso de los principales actores sociopolíticos que participaron en su formulación. Se realizó un estudio cualitativo para establecer como es percibida la política de focalización del gasto en salud por la población excluída, por los prestadores publicos y las autoridades locales, con base en grupos focales y entrevistas a profundidad. Se hizo también un seguimiento del acceso y uso de servicios medicos a partir de la definición de una condición trazadora. Finalmente, se formularon recomendaciones colectivas de política desde la perspectiva de la población excluída, de los prestadores y de las autoridades.

ABSTRACT

Background: Little information is available in Chile about hepatitis C virus (HCV) in hematological and oncohematological patients. Aim: To evaluate the prevalence of hepatitis C virus markers in a group of hematological and oncohematological pediatric patients seen at Valdivia Regional Hospital. Patients and methods: Antibodies against virus C, determined by ELISA and viral RNA, determined using RT-polymerase chain reaction, were measured in 54 blood samples from children with hematological diseases (34 with Acute Lymphoblastic Leukaemia, 4 with Hodgkin Diseases, 4 with Haemolytic Anemia, 5 with Sarcomas, 2 with Non-Hodgkin Lymphoma, 2 with Thrombocytopenic Purpura, 1 with an Ependimoma, one with a Wilms Tumor and 1 with a Von Willebrand Disease). Results: All samples were negative for antibodies against hepatitis C virus. Viral RNA was found in four children, all with a diagnosis of acute lymphoblastic leukemia and who received chemotherapy and multiple transfusions. Conclusions: The prevalence of Viral RNA for hepatitis C virus in oncohematological patients in our study is high and associated with the use of chemotherapy and multiple transfusions

ABSTRACT

Background: As sanitary and economic conditions improve, the prevalence of antibodies to hepatitis A is now significantly lower. Aim: To evaluate the prevalence of hepatitis A virus antibodies in healthy Chilean adults. Material and methods: Antibodies to hepatitis A virus were measured, using a commercial ELISA assay, in 215 voluntary blood donors (163 male, aged 19 to 30 years old) and 295 medical students and health personnel (156 male, aged 19 to 39 years old), residing in Valdivia, Chile. Results: Antibodies against hepatitis A virus were found in 68,2 percent of the total sample (351/510). Ninety percent of flood donors and 54 percent of health personnel and students were positive (p <0.01). Age specific prevalence in blood donors 19 to 22, 23 to 29 and 27 to 30 years old was 81,0 percent, 95,2 percent and 95,6 percent respectively. Among the same age groups in medical students, the prevalence was 47,9 percent, 53,2 percent and 61,9 percent respectively (p <0.01). Conclusions: This study indicates a reduction in the prevalence of hepatitis A virus antibodies among adults in Valdivia (Chile). Differences detected between individuals are probably related to different socioeconomic levels. Medical students have an increased risk for hepatitis A infections than the general population

ABSTRACT

Actualmente se considera que un tercio de la población humana se encuentra infectado por Mycobacterium tuberculosis. La tuberculosis mimetiza toda una variedad de padecimientos y, en el caso de su variante peritoneal que comprende del 0.7 al 2 por ciento de todos los casos registrados, puede comportarse clinicamente como cualquier otra patología abdominal. Por su parte, el vólvulo de sigmoides constituye una entidad con amplias variaciones geográficas, con una prevalencia de 0.2 por ciento en Occidente y con una tasa de mortalidad considerable del 30 por ciento. De etiología incierta, se relaciona con variaciones anatómicas, régimen dietético, constipación crónica, procesos inflamatorios localizados, enfermedades neurológicos, adherencias posquirúrgicas, embarazo, toxinas y enfermedades metabólicas. Presentamos un caso clínico en el que se conjugan estas dos patologías

ABSTRACT

Antecedentes: El objetivo de este estudio fue evaluar la utilidad de la irrigación a presión de la herida quirúrgica para disminuir su infección en enfermos apendicectomizados. Para ello se realizó un ensayo clínico aleatorio en enfermos con apendicitis. Material y métodos: Fueron incluidos 95 enfermos con apendicitis complicada. Los enfermos fueron asignados aleatoriamente a uno de dos grupos: Grupo I:40 pacientes apendicectomizados en los que sólo se empleó antibioticoprofilaxis y grupo II:55 enfermos apendicectomizados en los que además se realizó irrigación a presión de la herida quirúrgica. En ambos grupos se determinó la frecuencia de infección de la herida. Resultados: De los 95 casos incluidos, 67 correspondieron al sexo masculino (70.5 por ciento) y 28 al femenino (29.5 por ciento); la edad promedio fue de 28 años. Veintinueve casos (72.5 por ciento) presentaron infección de la herida quirúrgica en el grupo I y sólo nueve (16 por ciento) en el grupo II; esta diferencia fue estadísticamente significativa (p= 0.000001). Conclusiones: la irrigación a presión de la herida quirúrgica en enfermos con apendicitis complicada contribuye a disminuir la frecuencia de infección de la misma. Es barata, segura y accesible en cualquier quirófano
