Abstract: to evaluate the impact on access to, and use of, health services in colombia's new national health insurance system, the authors compared two cross sections of the population: before (1993) and after (1997), with the approval of act 100, creating the general system for social security in health (sgsss). two equity indicators were assessed: concentration curves (cc) and concentration indices (ci), summarizing the distribution of access to health care and utilization of health care services provided by the sgsss according to income deciles. between 1993 and 1997, the ci for access to insurance halved from 0.34 to 0.17; simultaneously, coverage increased from 23% to 57%, especially among the poorest segments of the population, where it increased from 3.7% to 43.7% as a result of subsidies provided by local governments. the ci for utilization of health care services did not vary significantly. increased disease prevalence and utilization of services among the insured, due to biased selection of risks and moral hazards, were also documented. these findings suggest a positive impact by the reform on inequalities in access to health care insurance; however, a similar effect on inequities in utilization of health services is not clear.

Abstract: Para evaluar el impacto sobre la equidad en el acceso y en la utilización de servicios de salud del nuevo Sistema General de Seguridad Social en Salud Colombiano (SGSSS), se compararon dos cortes transversales de la población, antes (1993) y después (1997) de promulgada la Ley 100, de 1993, que lo creó, con respecto a dos indicadores de equidad: las curvas (CC) e índices de concentración (IC) correspondientes a la distribución del aseguramiento y a la utilización de servicios. Entre 1993 y 1997, el IC en el aseguramiento se redujo a la mitad, del 0,34 al 0,17; simultáneamente, la cobertura del SGSSS se incrementó del 23% al 57%, sobretodo entre los segmentos más pobres de la población, donde pasó del 3,1% al 43,7%, como resultado de los subsidios otorgados por los gobiernos locales. Los IC en la utilización de servicios variaron muy poco. Adicionalmente, se detectó una mayor prevalencia de enfermedad y utilización de servicios entre los asegurados, debido a selección sesgada de riesgos y riesgo moral. Estos resultados sugieren un impacto positivo del SGSSS sobre las inequidades en el acceso al aseguramiento; sin embargo, no se evidenció un impacto claro sobre la equidad en la utilización final de servicios.

Abstract: De las 27 especies de primates colombianos, 19 están bajo algún tipo de amenaza debido principalmente a la pérdida de hábitat y al comercio ilegal de al menos 13 especies. Debido al alto número de individuos decomisados que resultan de los controles oficiales al tráfico ilegal, se ha planteado como alternativa de manejo su introducción o reintroducción en zonas protegidas. Hace siete a os, se introdujo una población de Saimiri sciureus, en 60 ha de bosque seco dentro de un parque recreativo, los cuales se mantuvieron en semicautiverio condicionado por suministro de alimento que implicaba un alto costo económico. En este trabajo se evaluó el efecto de la disminución progresiva de alimento sobre el comportamiento y la composición del grupo de primates. Se contrastaron los valores grupales con suministro y sin suministro de alimento artificial. La disminución gradual de alimento permitió al grupo adecuarse y aprovechar los recursos del medio a través también de un aumento progresivo en la exploración del hábitat. Se plantea esta estrategia como una alternativa viable de rehabilitación biológica.

Abstract: Acetaminophen is a drug used to treat many conditions as headache, muscle aches, arthritis, backache, toothache, and fever between others, but collateral effects of this drug are not well known yet. Here is tested its effect on proximal tubule epithelium. Acetaminophen (APAP) at doses of 200, 500, 1000 and 1500 mg/Kg i.p. caused cell damage and changes in F-actin distribution in the proximal tubule of male Wistar rats. After 48 hours of treatment, the proximal tubule epithelium showed tumefaction and necrosis. Dose of 200 mg/kg decreased the F-actin and was observed a structure in patches in the basal cytoplasm of epithelial cells of the proximal tubule. This effect was increased depending on the administered dose. Dose of 1000 mg/kg produced the highest histological damage and changes in the actin cytoskeleton. Results of this study suggested that nephrotoxic damage produced by high doses of APAP included breakdown of cytoskeleton in proximal tubule epithelium.

Abstract: objetive: to establish the effects on plasma osmolality and serum and urine electrolyte composition of the intake of three beverages with different osmolarities after a high intensity, long duration run in endurance athletes. methodology: nine long-distance runners performed 88 minutes of running on a treadmill (1% of inclination at a speed equivalent to 80% of the reserve heart rate), followed by 90 minutes of recovery; at the beginning there was no fluid replacement -dehydrated treatment- (dh); later on three sequential and randomized procedures were used, drinking equal volumes of one of three beverages, namely: hyperosmolar (hyper), hyposmolar (hypo) and isosmolar (iso). plasmatic osmolality and urinary osmolarity were measured by means of standard laboratory techniques, before and after the running period. results: in dh, at the end of the exercise period, a hypernatremic and hyperchloremic dehydration was observed (p < 0.05); throughout the procedure there was hyperkaliemia (p < 0.011); at the end of the recovery period there were an urinary volume reduction (p< 0.05) and hyperkaliuria (p < 0.001). partial replacement of the water loss, with beverages of different osmolarity, attenuated dehydration and the plasmatic changes of sodium and chloride, but not those of potassium at the end of the exercise period, or those of urinary potassium at the end of the recovery period. all studied variables, except for the urinary concentration of chlorine, were associated with the duration of the physical activity (p < 0.03); only the weight loss showed time-treatment association (p < 0.001). there were correlations with all treatments and during all procedures between plasmatic sodium and chloride (r: 0.85-0.96) and between urinary osmolarity and sodium (r: 0.50-0.83). conclusions: at the end of the physical activity there was, in the dh group, a hypernatremic, hyperchloremic and hyperkaliemic type of dehydration; partial replacement of the water loss, although in the low

Abstract: objetive: to establish the influence of ad libitum intake of hydrating beverages with different osmolarities on the percentage of body weight loss (%bw), the increase of heart rate (hr), and the percentage of plasma volume decrease (%pv) in athletes during a high-intensity and long-time run. methodology: after 9 warm-up minutes on a treadmill at a speed equivalent to 50% of the heart rate reserve, the athletes performed a run at 80% of the heart rate reserve speed, followed by 90 minutes of recovery. during the ' dehydrated treatment ' no fluid replacement was given, but during the ' hydrated treatments ' similar volumes were ad libitum drunk of each of three hydrating beverages, namely hyperosmolar (hiper), hypoosmolar (hipo) and isoosmolar (iso). results: in all treatments there were increases of the percentage of body weight loss (%bw) (p < 0.001) and of the hr (p < 0.05), and there was a correlation between the %bw and the increase of hr (p < 0.000); in the dh and hyper treatments a decrease of the percentage of plasma volume loss (%pv) (p < 0.05) was observed. an interaction treatment-time with the %wb was observed. conclusions: ad libitum intake of rehydrating beverages was less than the amount recommended in the international literature. that may have been the reason why the effects of osmolarity of such beverages on the analyzed parameters could not be determined. the amount of the %bw, the hr increase and the %pv decrease were proportional to the duration of physical activity. the relationship between the % bw and the %pv was modified by the osmolarity of beverages.

Abstract: Objetivo: establecer la influencia de la ingesta ad libitum de diferentes bebidas hidratantes sobre el porcentaje de pérdida del peso corporal (%PC), el aumento de la frecuencia cardíaca (FC) y la reducción porcentual del volumen plasmático (%VP) en deportistas sometidos a una actividad física de alta intensidad y larga duración. Metodología: luego de nueve minutos de calentamiento, en banda rodante con velocidad equivalente al 50% de la frecuencia cardíaca de reserva (FCR), siguieron 88 minutos de carrera, durante la cual la velocidad se incrementó al 80% de la FCR; al final, 90 minutos de recuperación. No se hizo reposición hídrica durante el tratamiento deshidratado (DH); durante los tratamientos con hidratación se emplearon volúmenes similares, ingeridos ad libitum, de cada una de tres bebidas, a saber: hiperosmolar (Hiper), hipoosmolar (Hipo) e isoosmolar (Iso). Resultados: se observó en cada uno de los tratamientos un aumento del porcentaje de pérdia del peso corporal (%PC) (p<0,001) y de la FC (p< 0,05) al igual que una correlación entre el %PC y el incremento de la FC (p<0,000); en los tratamientos DH e Hiper hubo una reducción del volumen plasmático (%VP) (p<0,05). Se observó interacción tiempo-tratamiento con el %PC. Conclusiones: la ingesta ad libitum fue menor que la cantidad recomendada en la literatura internacional, por lo que, probablemente, no se pudieron establecer los efectos de la osmolaridad de las bebidas hidratantes sobre las variables estudiadas. La magnitud del %PC, del incremento de la FC y de la reducción del %VP fueron proporcionales a la duración de la actividad física; la relación existente entre el %PC y la %VP se modificó por la osmolaridad de la bebida. Objetive: To establish the influence of ad libitum intake of hydrating beverages with different osmolarities on the percentage of body weight loss (%BW), the increase of heart rate (HR), and the percentage of plasma volume decrease (%PV) in athletes during a high-intensity and long-time run. Methodology: After 9 warm-up minutes on a treadmill at a speed equivalent to 50% of the heart rate reserve, the athletes performed a run at 80% of the heart rate reserve speed, followed by 90 minutes of recovery. During the “dehydrated treatment” no fluid replacement was given, but during the “hydrated treatments” similar volumes were ad libitum drunk of each of three hydrating beverages, namely hyperosmolar (Hiper), hypoosmolar (Hipo) and isoosmolar (Iso). Results: In all treatments there were increases of the percentage of body weight loss (%BW) (p < 0.001) and of the HR (p < 0.05),

Abstract: introduction: hepatocarcinoma generally develops in cirrhotic patients and its management depends both on the stage of the cirrhotic process and the stage of the tumor, with a registered world-wide increasing incidence. liver transplant is considered by many the best treatment option with curative intent in those patients that fulfill the corresponding inclusion criteria. materials and methods: all patients that received hepatic transplant at the liver transplant unit of the universidad de antioquia-pablo tobón uribe hospital (medellín, colombia) in the period april 2004-april 2008 were prospectively collected for analysis of diagnostic images and histopathology. included in the study were patients with the diagnosis of hepatocarcinoma and also those in which the hepatocarcinoma was an incidental finding. results: of the 153 transplants performed in the study period, 25 had the diagnosis of hepatocarcinoma established prior to transplantation, and in three patients it was an incidental finding. there were 21 men and 7 women. the etiology of the cirrhotic process was: hepatitis b, 28.6%, hepatitis c, 17.9%, followed by alcoholism, autoimmune disease, and others. in seven patients no hepatocarcinoma was found in the explant, although all had shown a single lesion diagnosed by images as hepatocarcinoma; since none were child a, the indication for transplantation was a complication of cirrhosis and not the tumor. correlation between images and pathology in the excised livers was better for mri than for ct, 53.8% versus 38.8%. discussion: liver transplant is the ideal treatment modality for patients with hepatocarcinoma and cirrhosis. it is clear that transplantation is restricted to patients with early stages of the tumor, according to the milano criteria. in spite of the refinement in the diagnostic imaging techniques, there is still frequent discrepancy between the preoperative imaging findings and the final pathology reports. however, this does not mean that there sh
