OBJECTIVE: To study the risk of Trypanosoma cruzi domestic transmission using an entomological index and to explore its relationship with household's characteristics and cultural aspects. METHODS: There were studied 158 households in an endemic area in Argentina. Each household was classified according to an entomological risk indicator (number of risky bites/human). A questionnaire was administered to evaluate risk factors among householders. RESULTS: Infested households showed a wide range of risk values (0 to 5 risky bites/human) with skewed distribution, a high frequency of lower values and few very high risk households. Of all collected Triatoma infestans, 44% had had human blood meals whereas 27% had had dogs or chickens blood meals. Having dogs and birds sharing room with humans increased the risk values. Tidy clean households had contributed significantly to lower risk values as a result of low vector density. The infested households showed a 24.3% correlation between time after insecticide application and the number of vectors. But there was no correlation between the time after insecticide application and T. infestans' infectivity. The statistical analysis showed a high correlation between current values of the entomological risk indicator and Trypanosoma cruzi seroprevalence in children. CONCLUSIONS: The risk of T. cruzi domestic transmission assessed using an entomological index show a correlation with children seroprevalence for Chagas' disease and householders' habits.

OBJECTIVE: To determine the intensity of Pediculus capitis infestation (abundance) among Argentinean schoolchildren. Children's sex and social stratum were analyzed as modifiers of the general prevalence and degree of parasitism. METHODS: The study included 1,370 schoolchildren (692 girls, 678 boys) from 26 schools of the province of La Rioja (21 public schools, five private schools). Classic prevalence was obtained as the percentage of children with nits and/or lice. Moreover, five degrees of parasitism were classified: 0) children with no signs of pediculosis; 0+) children with evidence of past infestation; 1) children with a recent infestation and low probability of active parasitism; 2) children with a recent infestation and high probability of active parasitism; 3) children with mobile lice (active pediculosis). RESULTS: The general prevalence was 61.4% (girls: 79%; boys: 44%, p<0.001). Private schools showed lower prevalence than public schools (p=0.02), especially due to the low prevalence in boys. Fifty percent of children were classified in classes 0 and 0+, 22% in class 1; and 28% in grades 2 and 3. The proportion of children in grade 3 was higher in public schools than in private schools. There were significant sexual differences in the intensity of parasitism for grades 2 and 3, where girls' rates exceeded twice those of boys'. CONCLUSIONS: Sex and social stratum are important modifiers of P. capitis general prevalence and degree of infestation. The classification of children by intensity of infestation allowed a more precise delimitation of this condition, which is especially important for disease surveillance and application of control measures.

Every month we see to be published dozens of scientific papers about etiology and physiopathology of CP, imaging, treatment, survival, quality of life of patients and of mothers (just a few) and so on. Papers dealing with the feelings and the problems of siblings of children and adults with CP in the most important scientific journals are extremely rare. However in internet we can find the sites of the most important Cerebral Palsy Societies, like the British, the Australian and the American ones already devoting a special attention to the issue of siblings; we also can see several interesting blogs of parents sharing their experiences not only with the handicapped child but also with the siblings, even counseling some books written for children giving practical advices how to deal and live with a handicapped sibling. What was a surprise to me were the several sites of adults having a disabled sibling, frequently with CP, in a new situation: without parents to care them.

Introduction In Triatominae, reproductive efficiency is an important factor influencing population dynamics, and a useful parameter in measuring a species' epidemiological significance as a vector of Trypanosoma cruzi (Chagas, 1909). The reproductive efficiency of triatomines is affected by food availability; hence, we measured and compared the effects of feeding frequency on the reproductive parameters of Triatoma patagonica (Del Ponte, 1929) and Triatoma infestans (Klug, 1934), and the effects of starvation on T. patagonica. Methods Couples from both species were fed weekly, or every 3 weeks; in addition, females in couples of T. patagonica were not fed. Each couple was observed weekly and reproductive efficiency was assessed on the following parameters: fecundity (eggs/female), fertility (eggs hatched/eggs laid), initiation and end of oviposition, initiation of mating, number of matings/week, and number of reproductive weeks. Relative meal size index (RMS), blood consumption index (CI), and E values (eggs/mg blood) were also calculated. Results Changes in feeding frequency affected the reproductive parameters of T. patagonica only, with a decrease in fecundity and number of reproductive weeks for those fed every 3 weeks, or not fed. The reproductive period, RMS index, and CI were lower for T. patagonica than T. infestans. However, despite the lower fecundity of T. patagonica, this species required less blood to produce eggs, with an E values of 2 compared to 2.94 for T. infestans. Conclusions Our results suggest that the differences in fecundity observed between species reflect the availability of food in their natural ecotopes.

Abstract: INTRODUCTION : Insects of the subfamily Triatominae are vectors of Trypanosoma cruzi , the Chagas disease parasite, and their flying behavior has epidemiological importance. The flying capacity is strikingly different across and within Triatominae species, as well as between sexes or individuals. Many Triatoma infestans individuals have wings but no flying muscles. In other Triatominae species, no clear relationships were found between wing length and flying behavior. If wing presence or size is not reflective of the flying behavior, which other parts of the body could be considered as reliable markers of this important function? METHODS : The genus Mepraia has exceptional characteristics with invariably wingless females and wingless or winged males. We calculated the porous surface exposed to odorant molecules to estimate the olfactory capacity of Mepraia spinolai . The head shape and thorax size were estimated using the geometric morphometric approach and traditional morphometric techniques, respectively. RESULTS : Alary polymorphism in M. spinolai was significantly associated with consistent modification of the thorax size, head shape, and notable change in the estimated olfactory capacity. The macropterous individuals had a larger olfactory surface and thorax size and significantly different head shape compared to those of the micropterous individuals. CONCLUSIONS: We concluded that these structural changes could be associated with the flying potential of Triatominae. Thus, morphological attributes not found on wings could help determine the likely flying potential of the bugs.

Aproximadamente 2500 alevinos de matrinchã com comprimento padrão de 0,8 a 5,0cm foram coletados no lago Catalão, margem direita do rio Negro e no rio Solimões, próximo a ilha da Marchantaria, Estado do Amazonas. Uma subamostra de 136 peixes foi retirada para exames parasitológicos e o restante foi colocado em tanques em uma estação de piscicultura, durante 30 dias. Após esse período uma segunda amostra foi retirada e examinada. Dos 136 peixes: 49 (36%) estavam parasitados com metacercárias de trematódeos; 32 (23,5%) com nematóides Spirocamallanus inopinatus; 26 (19%) com monogenóideos Jainus amazonensis; 3 (2%) com protozoários Trichodina sp.; 1 (0,7%) com acantocéfalo Echinorhynchus sp. e 2 (1,5%) com estágios larvais de cestóides. Dos peixes mantidos nos tanques, após 30 dias foi examinada uma subamostra de 60 peixes: 42 (70%) estavam parasitados com J. amazonensis; 14 (23%) com S. inopinatus; 9 (15%) com metacercárias de trematódeos e 2 (3%) com Echinorhynchus sp. A intensidade média e abundância média foram maiores em J. amazonensis (342 e 65), seguido por cestóides (70 e 1), Trichodina sp. (13 e 0,3), trematódeos (5 e 2), S. inopinatus (1 e 0,3) e Echinorhynchus sp. (1 e 0,007). Na estação de piscicultura a intensidade média e abundância média também foram maiores para o J. amazonensis (222 e 115) em relação aos demais grupos. A espécie J. amazonensis apresentou maior intensidade média e menor prevalência na natureza. Houve variação na composição da fauna parasitógica e nos índices de infestação, após 30 dias de permanência na estação de piscicultura.

Cátions e ânions majoritários são espécies químicas de grande importância nos diversos compartimentos aquáticos, porém, pouco abordados de forma exclusiva na bacia amazônica. Neste sentido, o objetivo deste estudo foi avaliar a dinâmica espacial de Na+, Ca2+, K+, Mg2+, Cl- e SO4 2- em um trecho do rio Solimões-Amazonas, levando-se em consideração a alcalinidade, potencial hidrogeniônico (pH), condutividade elétrica (CE), sólidos totais em suspensão (STS) e carbono orgânico total (COT). As coletas foram realizadas em maio, julho e setembro de 2012 em sete pontos na calha principal do rio Solimões-Amazonas e na foz de alguns dos principais tributários: rios Jutaí, Juruá, Japurá e Purus. Os cátions e ânions foram analisados por cromatografia de íons, STS por gravimetria, pH por potenciometria, alcalinidade por titulação potenciométrica, CE por condutimetria e o COT por oxidação catalítica por combustão. As concentrações médias dos cátions seguiram esta ordem Ca2+>Na+>Mg2+>K+ e dos ânions SO4 2->Cl-. De montante à jusante a tendência foi diminuição nas concentrações de cátions e ânions, das variáveis pH, CE, STS e alcalinidade, além do aumento das concentrações de COT. O presente estudo evidenciou mudanças nas características químicas sofridas pelo rio Solimões em seu curso. O aporte dos tributários pode ser apontado como um dos fatores responsáveis por essas modificações.

Si tenim en compte que el procés de traducció és un procés complex, el procés de traducció d'un text audiovisual encara ho és més. A part dels problemes tècnics com per exemple la sincronització labial i temporal hi ha altres factors a tenir en compte com és l'ús d'estructures lingüístiques i textuals específiques d'aquest canal de comunicació. Moltes de les pel·lícules que sovint podem veure a la pantalla estan produïdes als Estats Units, i per tant estan en anglès, i hi ha una necessitat imperiosa de traduir-les al català i castellà. A part d'això, en algunes ocasions el text audiovisual original conté més d'una llengua; aquest és el cas de Raid on Rommel i Butch Cassidy and the Sundance Kid, entre d'altres. En aquests casos, ens trobem amb una nova dificultat: el traductor ha de traduir aquesta tercera llengua (o dialecte) a la corresponent cultura d'arribada. Aquest article vol presentar i exposar alguns exemples d'aquest tipus de dificultats així com també les diferents solucions que s'han aportat davant una "tercera" llengua.

Les polítiques ambientals són el resultat d’un gran nombre de factors: el context social, el moment polític, el marc internacional, etc. En l’àmbit català s’ha demostrat que un factor que pot impactar de manera rellevant és l’aflorament de moviments ciutadans que reclamen canvis en les formes de fer política, encaminant-les cap a models més sostenibles. Malgrat sembli complicat que en el cas de l’energia es donin les condicions que van permetre el pas a la Nova Cultura de l’Aigua, no es descarta la possibilitat que s’arribi per altres mitjans a un canvi del paradigma energètic, ja que no tots els canvis són sempre apreciables des dels seus inicis.
