Revista Espa?ola de Enfermedades Digestivas , 2011,
Abstract: Background: chronic radiation proctopathy (CRP) is associated with recurrent rectal bleeding and transfusional requirements. Argon plasma coagulation (APC) and hyperbaric oxygen therapy (HOT) have been shown to be effective in the control of CRP. No prospective comparisons have been reported between these treatments. Aim: the aim was to evaluate the effectiveness, safety and impact on tissue toxicity of APC compared to HOT in patients with CRP. Material and methods: a prospective study for evaluating treatment response was conducted. Patients with cervical cancer and CRP with rectal bleeding were recruited. They had not received previous treatment. Collected data included: demographics, previous radiation dosage, duration and severity of rectal bleeding. Hemoglobin, transfusional requirements, and tissue toxicity (SOMA LENT questionnaire) at baseline and at 1, 2, and 3 months follow up were recorded. Results: thirty-one patients were included, 14 in the APC group and 17 in the HOT group. No response was noted in 13 and 18% of patients in the APC and HOT group respectively (p = NS). At the 1 and 2 months follow-up, the APC group showed a significantly better response in terms of transfusional requirements (0.6 vs. 3.4 and 0.7 vs. 2.5) and tissue toxicity score (5.3 vs. 8.6 and 3.8 vs. 7.248). After 3 months, both groups showed further improvement in all parameters without significant differences between them. Conclusions: APC and HOT were effective, safe and decreased the tissue toxicity scores in patients with CRP. However, response rate was higher and faster in the APC group. Introducción: la proctopatía por radiación (PPR) se asocia con rectorragía recurrente y requerimientos de trasfusiones. La coagulación con argón plasma (APC) y la terapia con oxígeno hiperbárico (HOT) han sido efectivas en el control de la PPR. No hay estudios prospectivos comparativos entre ambas técnicas. Objetivo: el objetivo del estudio es evaluar la efectividad, seguridad y el impacto en la toxicidad tisular de la APC comparado con el HOT en los pacientes con PR. Material y métodos: se realizó un estudio prospectivo para evaluar la respuesta al tratamiento. Se incluyeron a pacientes con cáncer cervicouterino y PPR con rectorragia recurrente, sin haber recibido tratamientos previos. Se tomaron datos demográficos, dosis de radiación, duración y severidad de la rectorragia, niveles de hemoglobina, requerimientos de trasfusiones y la toxicidad tisular (Cuestionario de SOMA-LENT) al inicio, y a los 1, 2 y 3 meses del tratamiento. Resultados: se incluyeron a 31 pacientes con PPR, 1

Revista Espa?ola de Enfermedades Digestivas , 2012,
Abstract: Background: gastric cancer patients are first diagnosed with an unresectable tumor in up to 40% of cases. Gastric outlet obstruction causes nausea, vomiting, dehydration and malnutrition. The aim of the study was to compare self-expanding metal stents to antrectomy and Roux-en Y gastrojejunostomy for palliation of obstructive adenocarcinoma of the gastric antrum. Methods: retrospective study in patients with obstructing cancer of the gastric antrum. Patients were divided into two groups: group A, underwent endoscopic placement of self-expanding metal stents and group B underwent surgical treatment with antrectomy and Roux-en Y gastrojejunostomy. Collected Data included: age, gender, performance status (Karnofsky's score), body mass index, histopathology, clinical stage (TNM classification), technical and clinical success of the procedure, time to oral intake, in-hospital stay, re-intervention rate, and complications related to the treatment and survival. Results: a total of 39 patients with gastric adenocarcinoma were included, 21 male and 18 female. Nineteen patients were assigned to group A and 20 patients to group B. There were no statistically significant differences between groups in regards to age, body mass index, Karnofsky's score and clinical stage. The technical and clinical success was similar for both groups. There was a statistically significant difference between groups favoring Self-expanding metal stent in time to oral intake (1 ± 0 vs. 4.9 ± 0.6 days, p = 0.0001) and in-hospital stay (0.94 ± 1.18 vs. 7.8 ± 7.7 days, p = 0.0005). We did not find statistically significant differences with regards to long-term survival. Conclusions: in patients with malignant gastric outlet obstruction due to gastric cancer, endoscopic palliation with self-expanding metal stents provide a shorter interval to oral intake, shorter in-hospital stay and lower rate of complications. Introducción: los pacientes con cáncer gástrico tienen un tumor irresecable hasta en el 40% de los casos. La obstrucción de salida gástrica ocasiona vómito, deshidratación y desnutrición. El objetivo de este estudio fue comparar las prótesis metálicas autoexpandibles con la antrectomia en el tratamiento paliativo del adenocarcinoma obstructivo del antro gástrico. Método: estudio restrospectivo en pacientes con adenocarcinoma obstructivo del antro gástrico. Los pacientes fueron divididos en dos grupos: grupo A) sujetos que fueron tratados mediante prótesis metálica autoexpandible y grupo B) aquellos que fueron tratados mediante antrectomía y gastroyeyunoanastomosis en Y de Roux.

Julio César Cepeda Ladino
Open Journal of Political Science (OJPS) , 2017, DOI: 10.4236/ojps.2017.71001
Abstract: The Pacific Rim has become a high-value geostrategic region because of the growing interdependence in its dynamics of political and economic cooperation. The international and regional cooperation systems continue their transformation since the early twenty first century, therefore it is quite relevant to be attuned with these processes. In recent years, Colombia has designed various strategies for international integration in the Asia-Pacific region within its Trans-Pacific foreign policy. It is essential for actors and interest groups to make a diagnosis to establish a forward-looking strategy to diversify the agenda of relations with this region. The purpose is to ensure a better understanding of the next transpacific cooperation schemes.

FUNCIONAMIENTO COGNITIVO: UN INEXTRICABLE JUEGO DE PéRDIDAS Y GANANCIAS
OSSA,JULIO CéSAR;
Acta Colombiana de Psicología , 2011,
Abstract: the purpose of this paper is to refer to the lotka-volterra model (predator-prey) in order to address cognitive functioning and particularly classification as a mental operation. logistic regression is used and a model is determined for explaining classification functioning in children four years old. results show evidence pointing to an on linear function of classification. the children’s performance suggests a balance between the number of questions that the child makes and the mental operations that he must display to coordinate such information.
Costos en el Sector Público Importancia de la Relación con la Presupuestación
Tiberio,Julio César;
Visi?3n de futuro , 2009,
Abstract: this paper has the intention to disclose the importance of the treatment of costs in the public sector, making known the necessity to analyze in depth and to think on the importance of its correct use, in order of satisfying the greater amount of possessions and services that the state (nation -provinces - municipalities), through its government programs, included annually in the public budget, allow to make specific the demands that the population has a right to receive, as it contributes the necessary resources for such an aim. for that, papers by distinguished professionals were selected, who have noticed the importance that the subject deserves. also methods or systems of costs were incorporated that will allow to make a specific budgetary proposal whose priority is based in the effectiveness, the efficiency and the economization in the obtaining of the public resources, and the destination of the expenses that allow the fulfillment of the foreseen goals for the fulfillment of the purposes that have as a non delegable objective, to obtain the well-being of the population. considering that the university studies plans, of the economic sciences do not often emphasize the importance of the public sector, specially in the public accountant's one, it is considered necessary that the students and the young professionals notice the importance of handling the public matter has, and the strict relation that exists between paying tribute - evasion - expenses and costs necessary to satisfy the necessities of the community, which is the reason of our preoccupation.
