Revista Colombiana de Psiquiatría , 2002,
Abstract: Objetivos: describir y analizar el perfil epidemiológico y los factores asociados al intento de suicidio en una muestra de la población Colombiana. Dise o: análisis secundario de la base de datos de la Primera encuesta nacional de salud mental y consumo de sustancias psicoactivas. Muestra: 25.135 personas fueron encuestadas. Se escogieron 21.988 personas de ambos sexos con edades entre 16 y 60 a os, a quienes se les aplicó la escala de Zung para ansiedad y depresión. Se midieron 240 variables independientes. Medida de desenlace principal: reporte de intentos de suicidio en el último a o y en la vida. Resultados: la prevalencia para intentos de suicidio en el último a o y a través de toda la vida fue de 1,2% (IC 95%: 1,06-1,34) y 4,25% (IC 95%: 4,25-4,81) respectivamente. Con la técnica de regresión logística para variables policótomas, los intentos de suicidio en el último a o estaban asociados con: edades de 16 a 21 a os OR = 2,5 (IC 95% 1,5-4,2), depresión grave OR = 11,8 (5,1-27,3), moderada OR = 5,3 (3,1-9,0) y leve OR = 3,6 (2,4-5,8), niveles moderados y graves de ansiedad OR = 3,4 (1,8-6,7). Se encontraron resultados similares cuando se consideraron los intentos de suicidio a lo largo de la vida. Conclusiones: el intento de suicidio en Colombia tiene una prevalencia similar a la de otros países, la población con mayor riesgo tiene entre 16 y 21 a os, presenta depresión o ansiedad, consulta al médico por 'nervios', es objeto de abuso verbal (particularmente en las mujeres) o tiene diferentes valores morales a los de su familia. Objectives: To describe and analyze the epidemiological profile and the associated factors to suicide attempt in a sample of the Colombian Population. Design: Secondary analysis of the First National Mental Health and Psychoactive Drugs Consumption Survey database. Sample: 25.135 persons were interviewed. The sample was chosen to be between 16 to 60 years old with a total group of 21.988 persons for this analysis. ZUNG anxiety and depression scales were applied. Two hundred and forty independent variables were measured. Principal end measurement: Self-report of suicide attempt in the last year and lifetime prevalence. Results: Prevalence for suicide attempt in the last year and lifetime prevalence were 1.2% (95% CI: 1.06- 1.34) and 4.25% (95% CI: 4.25-4.81) respectively. When a multiple logistic regression model was conducted, the suicide attempt in the last year was associated with: ages from 16 to 21 years (OR=2.5;CI 95% 1.5-4.2), severe (OR 11.8; 5.1-27.3) moderate (OR = 5.3; 3.1-9.0) and mild depression (OR = 3.6 ; 2.4-5

PhytoKeys , 2012, DOI: 10.3897/phytokeys.16.3186
Abstract: The páramos and high Andean forests of the tropical Andes are largely dominated by frailejones (Espeletiinae Cuatrec., Asteraceae). These plants are ecologically and culturally essential for both ecosystems and local inhabitants. The frailejones have been studied for over two centuries, but the taxonomic knowledge is still sparse and incomplete. The inedited monograph by Cuatrecasas contains only ca. 70% of the species known today, and publications in the last decade disagree regarding the number of taxa within the group, with estimates ranging from 3 genera and 90 species to 8 genera and 154 species. Moreover the literature contains inexact information about their distribution. As part of a study of the phylogenetic and biogeographic relationships of the group, a thorough revision of the nomenclature was needed as a first step. Currently the subtribe has 8 recognized genera, 141 species, 17 subspecies, 22 varieties, 8 forms, 33 recognized hybrids, 142 synonyms and 5 invalid names, for a total of 368 names (autonyms not counted). The most current list of taxa is presented here, along with some notes and Spanish names. Tamananthus crinitus V.M.Badillo is not included within the subtribe. Various previous species or infraspecific taxa (i.e. Carramboa tachirensis (Aristeg.) Cuatrec., Espeletia algodonosa Aristeg., E. aurantia Aristeg., E. brassicoidea var. macroclada, E. brassicoidea var. pedunculata, E. garcibarrigae Cuatrec. and Espeletiopsis cristalinensis (Cuatrec.) Cuatrec.) are proposed or confirmed as hybrids. Two new records for Colombia are mentioned: Ruilopezia cardonae (Cuatrec.) Cuatrec., which is the first report of Ruilopezia for that country, and Espeletia steyermarkii Cuatrec. Observations regarding the frequency of hybrids in the subtribe are also given.

Revista de Estudios Sociales , 2004,
Abstract: The present study tried to establish the attachment style, presence and severity of simple and complex posttraumatic stress, and the quality and quantity of relationships in the net of support of 15 soldiers that were kidnapped 3 years by las FARC, 14 months after their release. The following instruments were used: 1) Bartholomew Attachment Scale, 2) SIDES-CR self report Scale; 3) The Trauma Center Symptom Scale for PTSD; 4) Net of support format; and 5) A semi-structured interview format. Two profiles are proposed, based on the results. Significative differences (p>.05) were found between attachment styles, and a) The severity of Simple PTSD, intrusion and constriction symptoms, b) Presence and severity of Complex PTSD, and alterations in attention and consciousness, self-perception, and system of meanings. Also, between the presence and severity of simple and complex PTSD symptoms and: a) Attachment styles, b) Size of the net of support; and c) Communication quality, and tendency of family relationships. Relationships with captivity partners were the best ones and more solid of the net of support.

Abstract: a 46% of regeneration was obtained for explants without co-cultive using the cip-ms medium (2 mg· l-1 zr, 0,02 mg· l-1 ana, and 0,02 mg· l-1 ag3) developed in the international potato center. in order to improve the regeneration percentages, it was modified the proportion cytokinins:auxins of the cip-ms medium, obtaining 55% callus formation having a concentration of 2 mg· l-1 zr and 0.04 mg· l-1 ana. afterwards the effect of gibberellic acid was evaluated in this medium with 3 concentrations (0.02, 0.05, and 0.1 mg· l-1) obtaining 87.6% callus formation and 48.6% regeneration using the medium 2 mg· l-1 zr, 0,04 mg· l-1 ana, 0.02 mg· l-1 ag3 in explants under co-cultive conditions. this results were corroborated in a second regeneration assay under the co-cultive conditions with agrobacterium tumefaciens lba4404 transformed by the binary vector pnov022: similar callus formation and regeneration percentages where obtained. it has been reported an average 4 ± 3.3 regenerants/ callus using s. phureja stems, whereas, in the present research, an average of 15.2 ± 3 regenerants/callus was reported.
Interpretación clínica de los experimentos clínicos en cáncer
Torregroza-Diazgranados,Eduardo;
Revista Colombiana de Cirugía , 2005,
Abstract: the evaluation of the beneficial effects of a particular therapy is mandatory before deciding on a new treatment modality. clinicians that utilize the results of clinical trials to guide their practice need reliable tools for the evaluation of the clinical relevance of statistically significant results prior to the introduction of new cancer therapies. the purpose of this review is to propose the confidence intervals as useful tools to determine the clinical relevance of a treatment modality. the confidence interval attenuates the interpretation of clinical experiments solely on the basis of statistical criteria.

Interpretación clínica de los experimentos clínicos en cáncer Clinical interpretation of the clinical experiments in cancer
Eduardo Torregroza-Diazgranados
Revista Colombiana de Cirugía , 2005,
Abstract: La evaluación del beneficio de una terapia es crucial para decidir si un nuevo tratamiento debe ser usado. Los clínicos que utilizan los resultados de los experimentos clínicos para guiar su práctica médica necesitan herramientas útiles para evaluar la importancia clínica de los resultados estadísticamente significativos antes de introducir una nueva terapia en cáncer en la práctica clínica. El objetivo de esta revisión es proponer a los intervalos de confianza como los instrumentos útiles para juzgar la importancia clínica de un tratamiento, dado que éstas hacen explícita la evaluación del beneficio de una terapia y permiten atenuar el énfasis de la interpretación de los experimentos clínicos sólo con base en el criterio estadístico. The evaluation of the beneficial effects of a particular therapy is mandatory before deciding on a new treatment modality. Clinicians that utilize the results of clinical trials to guide their practice need reliable tools for the evaluation of the clinical relevance of statistically significant results prior to the introduction of new cancer therapies. The purpose of this review is to propose the confidence intervals as useful tools to determine the clinical relevance of a treatment modality. The confidence interval attenuates the interpretation of clinical experiments solely on the basis of statistical criteria.

Abstract: In this research, floristic composition and structure of vegetation of forests in the low basin of the SanSalvador River (Sierra Nevada de Santa Marta) were studied. Through the analysis of a satellite imageIKONOS, two types of forested cover were identified. Fifteen sample areas of 0.1 ha (15 000 m2) werelocated in the largest fragments of forest. 809 individuals with DBH = 10cm, belonging to 74 species and33 families were registered. According to the results, species diversity in the area is low with regard toother moist tropical forests and species richness varied from 7 to 19 species per plot. Distribution ofindividuals in DBH classes showed in the majority of sampled areas an inverted “J” shape trend, as it hasbeen reported in other tropical forests. The richest genera in terms of species were: Brosimum (Moraceae),Ficus (Moraceae), Licania (Chrysobalanaceae), Saurauia (Actinidiaceae) and Vismia (Guttiferae), eachof them with 2 species. These results represent a successful first phase to establish priorities for conservationof San Salvador river basin.
