Chlamydia trachomatis infection among asymptomatic pregnant women attending
Cueva Gómez Janeth, Mezones Holguín Edward, La Madrid Razurí Francisco, Castro Cruz Miguel, Holguín Mauricci Carlos, Valdes García Patricio, Arria Melissa, Rodríguez Morales Alfonso J.
Acta Cientifica Estudiantil , 2009,
Abstract: A cross-sectional descriptive study was conducted among asymptomatic pregnant women attending an antenatal clinic in Piura, northern Peru. Structured questionnaires were used to collect demographic and behavioral information, and clinical and gynecologic examinations were performed to detect clinical signs of infection. Cervical swabs were collected to detect the infection due to C. trachomatis using the direct immunofluorescence technique.C. trachomatis infection was detected in 11 (22%) of the 50 asymptomatic pregnant women. Multiple logistic regression analysis indicated that history of previous abortions (OR = 7.73) and history of previous sexually transmitted infections (STI) (OR = 4.45) were significant independent risk factors for chlamydial infection (P<0.05).A substantial prevalence of C. trachomatis infection in this asymptomatic pregnant women population was found in the study area. These results support a strategy of screening pregnant women for bacterial STIs (followed by treatment of infections), which could be integrated into routine pregnancy care in northern Peru.

Abstract: El suicidio es un fenomeno complejo que involucra aspectos psicológicos, biológicos y sociales. En Colombia, los datos reportados en Forensis 2004, muestran que si bien el número de suicidas disminuyó, aunque no significativamente con respecto al a o anterior, sigue en aumento la proporción de jóvenes que se quitan la vida.
Reformas comerciales y cambios en el precio al productor de maíz en México
Contreras Castillo, José María;Gómez Uribe, Janeth Magdalena;
Perfiles latinoamericanos , 2009,
Abstract: this paper uses a method to break down the changes in domestic prices for maize producers in mexico during the 1994-2005 period as well as to measure the relative contribution of the variations in the international price, the exchange rate movements and the modification of the trade policy. one can conclude that the elimination of import permits, combined with the mexican government's decision to apply zero import fees and not to implement the agreed import duty elimination timeline, are the main factors that explain the reduction of domestic prices for maize producers. nevertheless, in the context of a greater transmission of prices, the reduction in the maize international price and the appreciation of the real exchange rate also contribute to this fall.
Differences in behavior associated to anxiety in male and Female rats exposed to a chronic stress protocol: Early maternal separation

Suma Psicológica , 2009,
Abstract: During the first stages of life, the environment and maternal interactions are essential for normal mammalian neuronal maturity and behavior. In fact, it has been demonstrated that disruption of mother-pup interaction during early life exert long-lasting effects on the development of central nervous, endocrine, and immune systems and behavioral responses. The principal aim of our work was to study the consequences of early maternal separation (EMS) on adult male and female anxiety. The behaviors was evaluated using the Elavated Plus-Maze (EPM). Separation procedure was carried out in postnatal days 1 to 21 twice daily: three hours in the morning and three hours in the afternoon. As a control group we used animals that stayed with the mother but were manipulated daily for one minute in the morning and in the afternoon. In postnatal day 22, animals were distributed by sex and then kept in standard lab conditions. Behavioral testing in the EPM was performed at 90/95 days of age. All subjects were videotaped. Records included number of entries, time spent in each arm, and the frequency and time stretching, deeping, rearing, and grooming. Our results showed that separated females have more open arm entries and spent more time there, and exhibit more deeping and less grooming compared to females in the control group and males of the experimental and control group. Thus, based on the anxiolytic profile that female rat shows in the EPM, these data suggest that EMS affects differentially male and female adult rats
Use of results of public health research in a governmental institution of Colombia

Abstract: Background: Research is an essential function of public health. Great amounts of resources are spent in health research that should contribute to improve people’s health. However, impact or social gains of health research have been insufficiently measured. Objectives: To explore perceptions of policy-makers and researchers about research use in public health and to identify barriers and facilitators for using research results at a Departmental Secretariat of Health, in Colombia. Methods: We carried out a case-study about perceptions of use of research results in the Valle del Cauca Secretariat of Health using a semi-structured interview with 17 health policy makers and researchers. Researchers in health research institutions and health officials in the Secretariat of Health were selected by purposing sample. We identified preliminary and emergent categories; relations between them and suggested explanations of the issues under study were established. Main results: Policy makers to guide decisions in public health at the Departmental Secretariat of Health do not use research results. Barriers for using research results are associated with the lack of a research policy, deficiencies in research management structure and exclusive contractual relationships established between researchers and policy-makers. There are few experiences in using research results and they were facilitated by a better knowledge of health officials about research process, a participative role of them in research, and by characteristics of research development. Conclusions: Research results do not contribute to make decisions at the Secretariat of Health.

Abstract: A test has been developed for early identification of the casual agent for potato powdery scab (Spongospora subterranea fs subterranea). Identification was carried out in seeds and soil where this tuber is grown. A polymerase chain reaction (PCR) was set up for detecting 372, 390 and 391 bp ribosomal DNA internal transcribed spacer sequences (ITS) in the S. subterraneagenome. A method for extracting and purifying DNA from infected plant material (potato root nodes and pustules on the potato) was standardised. Plant tissue was obtained by potato tuber propagation using an inoculum from the pathogen in greenhouse conditions. After the PCR had been optimised and its sensitivity determined, a molecular methodology was validated by examining plant material infected with S. subterranea and soil samples infested with the pathogen obtained from the departments of Cundinamarca and Nari o. The PCR detected S. subterranea DNA from infected material and soil samples (all thirty samples from the experimental area analysed proved PCR positive). These results show that this molecular method was not just useful for the early detection of the pathogen in soil samples but as a tool for detecting or determining the possible presence of this micro-organism in places that have been declared f ree of S. subterranea and an effective form of quality control in producing the certif ied potato seed. Key words: Powdery scab, cystosori, internal transcribed spacer, PCR, plasmodiophorid. Con el fin de identificar de manera precoz el agente causal de la sarna polvosa de la papa (Spongospora subterranea fs subterranea) tanto en semillas como en suelos aptos para el cultivo de este tubérculo, se ha desarrollado una prueba basada en la reacción en cadena de la polimerasa (PCR) para la detección de tres secuencias ITS (espaciadores de transcripción interna específicos del ADNr) de 372,390 y 391 pb presentes en el genoma de S. subterranea. Para ello se estandarizó una metodología de extracción y purificación de ADN del microorganismo a partir de tejido vegetal infectado (agallas de raíz de papa y pústulas en papa) obtenido en pruebas de propagación del patógeno en invernadero. Una vez optimizada la PCR y determinada su sensibilidad, se validó la metodología molecular examinando muestras de tejido vegetal infectado y suelo infestado por el patógeno, provenientes de los departamentos de Cundinamarca y Nari o. La PCR detectó ADN del microorganismo tanto en el material vegetal infectado, como en las muestras de suelo analizadas (las 30 submuestras del área experimental fueron PCR positivas).

Abstract: En 1992, Stephen R. Barley y Gideon Kunda, profesores de la universidad deStanford y de la universidad de Tel Aviv respectivamente, publicaron un estudiotitulado: “Desing and devotion: surges of rational and normative ideologies ofcontrol in managerial discourse”* en el que encontraron que en Estados Unidos,las teorías administrativas se presentan en oleadas de retórica en correspondenciadirecta con los ciclos económicos. De esta manera, las teorías de contenido racional(dirigidas al control del trabajo) sobresalen en períodos de crecimiento, y las decontenido normativo (dirigidas al control del trabajador) prevalecen en contraccióneconómica. Partiendo de estos resultados, y retomando la esquematizaciónhistórica del surgimiento de las oleadas de ideología administrativa en Colombiaplanteada por el profesor Francisco López G. (1998), aquí se realizó un estudiosimilar y se encontró que el desarrollo del pensamiento administrativo en Colombiatiene igualmente relación con el ciclo económico, emerge en oleadas y presentacaracterísticas particulares. Professors Stephen R. Barley and Gideon Kunda (1992) conducted a study titled: “Design and Devotion: Surges of Rational and Normative Ideologies of Control in Managerial Discourse” in which they found that in the United States management theories are presented in waves of rhetoric which corresponded directly with economic cycles. In this way, theories with rational content (those directed at controlling work) stand out in periods of growth, while those with normative content (those directed at controlling the worker) prevail in times of economic shrinking. Based on these results, and returning to the historical scheme of the appearance of waves of management ideology in Colombia proposed by professor Francisco López G. (1998), a similar study was conducted in which the development of management thinking in Colombia was found to also have a relation to the economic cycle, to emerge in waves, and to have particular characteristics.

Abstract: Resumen SummaryAntecedentes: Las lesiones hematooncológicas son un grupo de neoplasias generadas por alteraciones células progenitoras hematopoyéticas. Este tipo de lesiones afectan a la población en general, con un porcentaje importante de ocurrencia en la población infantil. En el área Metropolitana de Bucaramanga (AMB) estos trastornos se ubican dentro de las lesiones malignas más frecuentes region (2000 - 2004). Metodología: El Registro Poblacional del AMB realiza un proceso de búsqueda y verificación IACR, activa de los casos de cáncer en la población residente AMB desde el 2000. Luego de los procesos de validación, los casos son codificados y digitados en CanReg-4 con el cual se estiman frecuencias y tasas de software. Este informe tiene datos verificados y actualizados que incluyen los obtenidos en el proceso de validación de egreso hospitalario y registros de mortalidad. Resultados: Entre 2000 y 2004 se captaron 620 casos de neoplasias hematolinfoides ubicándose en los primeros lugares tanto en hombres como en mujeres, con un mayor número de casos en los hombres especialmente por casos de leucemia linfoide. Se encuentra tasa cruda de 10.9 casos Conclusión: Comparando con las cifras del proyecto , el comportamiento de las neoplasias hematológicas en esta región es similar a lo estimado para el área Metropolitana de Bucaramanga
