RESUMEN

Resumen Objetivo: Describir los conocimientos, las actitudes y las prácticas acerca de la toxoplasmosis en dos comunas de Armenia, Quindío, con alta prevalencia de la infección. Metodología: Estudio descriptivo con población de dos comunas de Armenia, Quindío. Se aplicó un cuestionario autodiligenciado tipo conocimientos, actitudes y prácticas. Esta herramienta incluyó elementos sobre el parásito Toxoplasma gondii, sus vías de transmisión, aspectos clínicos, diagnósticos y de tratamiento generales, así como prácticas para evitar la infección. El instrumento se aplicó antes y después de una intervención educativa. Se describieron las frecuencias en el número de respuestas correctas antes y después de la intervención para cada comuna. Resultados: Participaron 27 personas, con una media de edad de 57 años. El 59 % fueron mujeres. El 48% había completado la educación media y el 40,7 % la primaria. El conocimiento del agente causal antes de la intervención fue del 22 %, mientras que posterior a la intervención fue del 92,3 % en la comuna 1 y del 81,8 % en la comuna 6. Posterior a la intervención, cerca del 90 % de los encuestados reconoció la retina como la principal estructura afectada y todos los encuestados reconocieron el consumo de agua hervida como factor protector. Conclusión: Los conocimientos sobre la toxoplasmosis en las dos comunas eran limitados. Luego de la intervención educativa, se evidenció un aumento en el porcentaje de respuestas correctas en la mayoría de las preguntas. Se recomienda realizar nuevas intervenciones educativas y en salud pública, para evaluar los efectos de estas a largo plazo.

Abstract Objective: To describe knowledge, attitudes and practices related to toxoplasmosis in two districts of high prevalence in Armenia, Quindío. Methodology: descriptive study; the population of two districts of Armenia, Quindío were engaged. A self-administered questionnaire regarding knowledge, attitudes, and practices was applied. This tool included elements related to Toxoplasma gondii, its transmission pathways, general clinical, diagnostic and treatment aspects, as well as practices to prevent infection. The instrument was applied before and after an educational intervention. Frequencies were described as the number of correct answers before and after the intervention for each district. Results: 27 people participated, with an average age of 57 years. 59 % were women; 48 % had completed high school and 40.7 % had completed elementary school. Before the intervention, the knowledge of the causal agent was 22 %, while after the intervention, it was 92.3 % in district 1 and 81.8 % in district 6. After the intervention, about 90 % of participants recognized the retina as the main compromised structure and all participants recognized the consumption of boiled water as a protective factor. Conclusion: The knowledge regarding toxoplasmosis in the two districts was limited. After the educational intervention, there was an increase in the percentage of correct answers in most of the questions. New educational and public health interventions are recommended to assess the long-term effects of these interventions.

RESUMEN

Polymorphic genetic markers and especially microsatellite analysis can be used to investigate multiple aspects of the biology of Plasmodium species. In the current study, we characterized 7 polymorphic microsatellites in a total of 281 Plasmodium vivax isolates to determine the genetic diversity and population structure of P. vivax populations from Sudan, Madagascar, French Guiana, and Armenia. All four parasite populations were highly polymorphic with 3-32 alleles per locus. Mean genetic diversity values was 0.83, 0.79, 0.78 and 0.67 for Madagascar, French Guiana, Sudan, and Armenia, respectively. Significant genetic differentiation between all four populations was observed.

RESUMEN

Paints with high lead concentrations (ppm) continue to be sold around the world in many developing countries and those with economies in transition representing a major preventable environmental health hazard that is being increased as the economies expand and paint consumption is increasing. Prior lead paint testing had been performed in Brazil and India and these countries were selected to examine the impact of a new regulatory limit in Brazil and the impact of efforts of non-governmental organizations and others to stop the use of lead compounds in manufacturing paints. Armenia and Kazakhstan, in Central Asia, were selected because no information on lead concentration in those regions was available, no regulatory activities were evident and non-governmental organizations in the IPEN network were available to participate. Another objective of this research was to evaluate the lead loading (µg/cm(2)) limit determined by X-Ray Fluorescence (XRF) for areas on toys that are too small to obtain a sample of sufficient size for laboratory analysis. The lead concentrations in more than three-fourths of the paints from Armenia and Kazakhstan exceeded 90 ppm, the limit in the United States, and 600 ppm, the limit in Brazil. The percentages were about one-half as high in Brazil and India. The average concentration in paints purchased in Armenia, 25,000 ppm, is among the highest that has been previously reported, that in Kazakhstan, 15,700 ppm, and India, 16,600, about median. The average concentration in Brazil, 5600 ppm, is among the lowest observed. Paints in Brazil that contained an average of 36,000 ppm before the regulatory limit became effective were below detection (< 9 ppm) in samples collected in the current study. The lack of any apparent public monitoring of paint lead content as part of regulatory enforcement makes it difficult to determine whether the regulation was a major factor contributing to the decline in lead use in these paints. Using data from the current study and those available from other studies 24 of 28 paints from major brands in India decreased from high concentrations to 90 ppm or lower. Since lead concentrations in golden yellow paints from these brands were found to decrease to ≤ 90 ppm, it is possible that all 28 of these paints now contain ≤ 90 ppm since yellow paints usually have the highest lead concentrations. Other brands in Brazil and India that have been analyzed only one time had lead concentrations up to 59,000 ppm and 134,000 ppm, respectively. Less than one-third of the paints had notations on their labels with information about lead content and these were sometimes inaccurate. The label from one brand indicating "no added lead" contained paint with 134,000 ppm lead, the highest found in this study. Three percent (3 of 98) of the paints with surface lead loading that did not exceed 2 µg/cm(2), the limit established by the Consumer Product Safety Improvement Act for small areas on toys, contained greater than 90 ppm lead and thus were false negatives. Of the new paint samples that contained ≤ 600 ppm, 88% contained ≤ 90 ppm. Of the samples that contained ≤ 90 ppm, 97% contained ≤ 45 ppm and 92% contained ≤ 15 ppm. Based on these data it appears to be technically feasible to manufacture paints containing ≤ 90 ppm and in many cases to produce paints that have lead concentrations that do not exceed 15 ppm.

RESUMEN

Se planteó indagar acerca de la existencia de trastorno de personalidad antisocial en consumidores de heroína, tomando una muestra de 10 heroinómanos, con edades comprendidas entre los 18 y 45 años, para lo cual se realiza un estudio cuantitativo ­ descriptivo de corte transversal, cuya población era de estrato socio-económico bajo, perteneciente a 4 barrios de la ciudad de Armenia. Para ello, se empleó un cuestionario elaborado bajo los criterios del Trastorno de Personalidad DisociaI/Antisocial evaluados por el Manual Diagnóstico y Estadístico de Trastornos Mentales (DSM-IV TR), valorado por expertos antes de su aplicación. Teniendo en cuenta los resultados más representativos, el 90% coincidió en ser impulsivos/agresivos y permaneció fuera de casa por un largo periodo de tiempo a pesar de las prohibiciones paternas, iniciando este comportamiento antes de los 13 años de edad. Asimismo el 80% hurtóobjetos sin generar daño a otro, presentó dificultad para mantener un empleo y mintió para satisfacer necesidades personales. De acuerdo a las cifras encontradas se sugiere la implementación de estrategias de prevención e intervención en políticas de salud mental.

One considered to investigate about the existence of upheaval of antisocial personality in heroin consumers, taking a sample from 10 heroin addicts,with ages between the 18 and 45 years, for which a quantitative study is realised - descriptive of it cross section, whose population era of low socio-economic layer, pertaining to 4 districts of the city of Armenia. For it, a questionnaire made under the criteria of the Upheaval of Antisocial DisociaI Personality was used/evaluated by the Manual Statistical Diagnosis and of Mental Upheavals (DSM-IV TR), valued by experts before its application. Considering the most representative results, 90% agreed in being impulsive/aggressive and remained abroad by a long period of time in spite of the paternal prohibitions, initiating this behavior before the 13 years of age. Also 80% stole objects without generating damage to another one, presented/displayed difficulty to maintain a use and lay to satisfy personal needs. According to the found numbers the implementation of strategies of prevention and intervention in policies of mental health is suggested.

RESUMEN

Spatio-temporal distribution of epifauna collected with a sledge was studied on the Cilician shelf of the Mediterranean Sea. There were two different communities: the shallow community was restricted to water at 5 and 10 m deep with sandy bottom inhabited abundantly by Conomurex persicus, Arnoglossus laterna and Murex trunculus. Conomurex persicus, an introduced tropical species predominated the shallow zone and distinguished it from the deep zone. The deep community (25-150 m) lacked shallow water species and was dominated by Arnoglossus laterna, Goneplax rhomboides and Parapenaeus longirostris. Seasonality was not a major factor in the epibenthic community structure of the entire shelf, but it is in the shallow waters. Bottom depth was main factor for structuring the community on the shelf. Sediment size and organic content is also a controlling factor for the distribution of the epibenthic fauna. Rev. Biol. Trop. 56 (4): 1919-1946. Epub 2008 December 12.

Se estudió la distribución espacio-temporal de la epifauna recolectada con un trineo en la plataforma de Armenia Menor, Mar Mediterráneo. Hubo dos comunidades diferentes: una comunidad de aguas someras entre los 5 y 10 metros de profundidad con fondo arenoso habitado en forma abundante por Conomurex persicus, Arnoglossus laterna y Murex trunculus. Conomurex persicus, una especie tropical introducida, predominó en la zona de aguas someras, y la diferenció de la zona profunda. La comunidad profunda (25-150 m) no presentaba especies de aguas someras y estaba dominada por Arnoglossus laterna, Goneplax rhomboides y Parapenaeus longirostris. La estacionalidad no fue un factor importante en la estructura de la comunidad epibentónica presente en toda la plataforma, pero sí lo fue en las aguas someras. La profundidad del fondo del mar fue el factor principal en la estructura de la comunidad en la plataforma. El tamaño del sedimento y el contenido de materia orgánica es también un factor que controla la distribución de la fauna epibentónica.
