Objetivo: Identificar el valor predictivo de mortalidad de la escala GAP (Escala de coma de Glasgow, Edad y Presión arterial sistólica) medida durante la fase prehospitalaria en pacientes con lesiones por trauma ingresados a la sala de emergencia del Hospital General San Juan de Dios, durante los meses de Agosto a Noviembre de 2018. Materiales y métodos: Estudio, transversal, descriptivo, realizado en lugar y fecha descrita, en 420 pacientes, que cumplen criterios de lesión por trauma con asistencia prehospitalaria; datos recabados por la boleta de recolección de datos. Resultados: El estudio se realizó con la finalidad de evaluar el sistema de puntuación GAP, el cual establece un valor predictivo de mortalidad, siendo estas variables proporcionadas por los cuerpos de socorro en la sala de urgencias del Departamento de Cirugía. Clasificando a los paciente en grupos de bajo, moderado y alto riesgo de mortalidad; siendo 363 pacientes (86.4%) clasificados como bajo riesgo, 46 pacientes (11%) como riesgo moderado y 11 pacientes (2.6%), como alto riesgo de mortalidad. Se analizaron los resultados, indicando que el VPP para la escala GAP es del 100%, mientras que el VPN es del 91%. Con una sensibilidad del 24%, sin embargo, su especificidad es del 100%, por lo que una clasificación apropiada de alto riesgo de mortalidad es un predictor determinante en nuestro contexto hospitalario. Conclusión: El sistema de puntuación GAP es una herramienta útil para el triage objetivo intrahospitalario por su alta precisión en el pronóstico de mortalidad en lesiones por trauma.

Este estudio analiza cómo las adolescentes de niveles socioeconómicos bajos en la ciudad de Cartagena, Colombia, han construido sus creencias y prácticas sobre la sexualidad. El diseño de la investigación es de tipo cualitativo, específicamente con un enfoque etnográfico centrado en lo que las participantes expresaron en cuanto a sus experiencias, actitudes, valores, roles, tradiciones y creencias. Igualmente, se analizó la apropiación de conductas que generan estilos de vida y formas de relacionamiento que inciden sobre la presencia del embarazo a temprana edad. Se observó que las creencias y prácticas de sexualidad de estas jóvenes adolescentes se han construido de lo que culturalmente se ha transmitido de generación en generación, ejerciendo una gran influencia la dinámica social, los mecanismos de ocio y esparcimiento. This study analyzes the way teenagers from low socio-economic levels construct their beliefs and practices on sexuality. The research is qualitative, and specifically designed with an ethnographic approach, which is centered on the participants' description of their experiences, attitudes, values, roles, traditions, and beliefs. Also analyzed was the adoption of lifestyle-forming behaviors that construct relationships and affect the teenage pregnancy rate. That the teenagers' beliefs and practices on sexuality are the result of their cultural and traditional knowledge, the prevalence of their social dynamics, and their leisure and recreation activities was also observed.

espanolEl proposito de esta investigacion es encontrar en que medida la participacion en distintos tipos de voluntariado se asocia con mayores niveles de satisfaccion vital, compromiso organizacional y desempeno civico. La muestra del estudio consta de 49 participantes, voluntarios de proteccion civil, 36.7%, un refugio de animales, 36.7%, y un grupo de teatro, 26.5%, con un rango de edad entre 19 y 58 anos. Los resultados muestran que el tipo de voluntariado no mantiene relacion con la puntuacion en las tres variables, probablemente debido al tamano de la muestra. Se encontro que a medida que aumenta la edad aumenta la puntuacion en desempeno civico y compromiso organizacional, y que existe una correlacion positiva entre desempeno civico y compromiso organizacional. No se encontraron diferencias con respecto al sexo en las distintas variables. EnglishThe purpose of this research study is to determine the extent to which participation in different types of volunteer work is associated with higher levels of life satisfaction, organizational commitment and civic performance. The sample for the study consists of 49 participants, volunteers in civil defense, 36.7%, an animal shelter, 36.7%, and a theater group, 26.5%, with an age range from 19 to 58 years old. The results show no correlation between type of volunteer work and the score on the three variables used, presumably due to the size of the sample. It was found that the older the person the higher the score on organizational commitment and citizenship performance. A correlation was also found between organizational commitment and civic performance. There were no differences between sexes in the variables.

RESUMEN. Antecedentes: Se busca desarrollar injertos oseos biocompatibles capaces de regenerar defectos oseos de tamano critico. Objetivo: Evaluar la biocompatibilidad in vivo del fosfato tricalcico con quitosano (FTQ) en piel, musculo y hueso. Metodologia: Se asignaron 15 ratas Wistar a grupos A (piel), B (musculo), C, D y E (defectos oseos de tamano critico). Se implanto FTQ en cada tejido. Como control se colocaron esponjas de colageno adyacente a los sitios evaluados. Las ratas de los grupos A y B se sacrificaron a los 20 dias, mientras que las de los grupos C, D y E se sacrificaron a los 20, 40 y 80 dias respectivamente. Para confirmar la biocompatibilidad del FTQ, se evaluo la respuesta inflamatoria en terminos de porcentaje: ninguna (0 %), leve (˂30 %), moderada (30-50 %) y alta (˃50 %), despues de 20, 40 y 80 dias en el tejido oseo. Resultados: No se encontro ulceracion ni supuracion en piel, musculo o hueso. Despues de 80 dias, el FTQ se observaba incorporado a tejido fibrotico y oseointegrado al hueso nativo. Conclusion: El FTQ fue biocompatible in vivo en piel, musculo y hueso. ABSTRACT. Background: It is necessary to develop bone grafts capable to regenerate critical size bone defects. Objective: To evaluate the biocompatibility in vivo of tricalcium phosphate with chitosan (TPC) in skin, muscle, and bone. Methods: 15 Wistar rats were assigned to groups A (skin), B (muscle), C, D, and E (bone). TPC was placed in each tissue. In groups C-E, critical size bone defect was grafted with TPC and collagen sponge was placed adjacent to test sites as a control. Animals from groups A and B were sacrificed after 20 days, while groups C-E at days 45, 60, and 80. Inflammatory response was evaluated in all tissues. To assess biocompatibility, the percentage of cells was evaluated as none (0 %), low (˂ 30 %), moderate (30- 50 %), and high (˃50 %). Results: There were no signals of ulceration or suppuration in skin, muscle, and bone. After 80 days, TPC was incorporated into a fibrotic structure and osseointegrated to native bone. Conclusion: TPC was biocompatible with skin, muscle, and bone.

Objective: to measure the effect of partner’ s violence on women’s mental health asking help to the Family Commissaries of Cali, Colombia. Methodology: cross-sectional design with a sample of women that denounce their situation to the Family Commissaries of Cali. The Check List of Symptom -SCL-90R, the Conflict Resolution Tactics and the Resilience scales are applied. Results: the sample comprises 100 women. The Global Distress Index is 1.36; the Distress Index for Positive Symptom is 2.27; nine dimensions of symptoms obtain high scores. Comparison with normative samples of psychiatric out-patients do not show statistical significant differences for most of the indexes; 60% of women present post-traumatic stress disorder. Discussion: the findings are similar to normative samples from psychiatric out – patients. The partner’s violence effect on mental health is considerable and calls for action. Women have needs related with care. They need help to gain or develop personal skills and external resources to handle partner’s violence.

BACKGROUND Glutathione (GSH) is the principal intracellular defense against oxidants, and HIV-infected individuals tend to have subnormal concentrations in plasma. This GSH deficiency may contribute to the pathogenesis of disease progression. In the pediatric population correlations between GSH concentrations with clinical, immunologic and virologic disease profiles are scarce. OBJECTIVES The main objectives of this study were (1) to compare plasma GSH concentrations of HIV-infected children and healthy controls and (2) to correlate GSH values with clinical, immunologic and virologic disease indices. METHODS Twenty-four HIV-infected and 24 healthy control children entered the study. Plasma concentrations of total glutathione and related thiols were determined. RESULTS The difference in mean plasma GSH concentrations between HIV-infected (2.96 +/- 0.31 microM) and control (6.62 +/- 0.58 microM) groups was highly significant (P < 0.0001). Linear regression analyses in HIV-infected patients revealed significant correlations between GSH and both absolute CD4+ cell counts (r = 0.56, P = 0.004) and viral load measured as log HIV-RNA PCR (r = -0.49, P = 0.018). GSH concentrations did not significantly correlate with CDC clinical stage but were lower in HIV-infected patients with growth failure (1.60 +/- 0.54 microM) vs. non-growth failure (3.23 +/- 0.33 microM); P = 0.05. CONCLUSIONS This study confirmed that HIV-infected children are deficient in plasma GSH concentrations compared with healthy controls. We documented that low GSH concentrations in HIV-infected children are directly correlated with CD4+ cell counts and inversely correlated with viral loads. These findings support a possible role of GSH in the pathogenesis of HIV disease progression.
