La teoría de las transiciones como paradigma de apoyo al automanejo en personas con condiciones crónicas / Transitions theory as a paradigm for supporting self-management in people with chronic conditions / A teoria das transições como paradigma para apoiar a autogestão em pessoas com condições crónicas

Resumen Introducción: La experiencia de vivir con una enfermedad crónica no es una tarea sencilla, se requiere de herramientas que permitan aumentar el grado de conciencia para enfrentar las necesidades y superar desafíos sobre el estado de salud y enfermedad. En los últimos años, se ha instaurado el apoyo al automanejo, con la finalidad de potenciar las habilidades en personas con este tipo de afecciones. Resulta trascendental considerar como desde enfermería se puede contribuir al logro de aquello. El objetivo del presente ensayo es reflexionar acerca de la teoría de las transiciones de Meléis como paradigma de apoyo al automanejo en personas con condiciones crónicas. Desarrollo: La teoría de las transiciones de Meléis establece que las personas están en constante cambio, tal como ocurre en el proceso de transición de salud-enfermedad. Recibir el diagnóstico de una enfermedad crónica, conlleva una serie de procesos complejos para la persona, debido a la multiplicidad de variables que ello implica. La teoría de Meléis entrega lineamientos para orientar a la persona profesional de enfermería sobre elementos claves e interrelacionados, como la concepción previa de la naturaleza de la transición y sus condiciones, lo que servirá para la planificación de modalidades de intervención congruentes con las experiencias de la persona y su evaluación en el transcurso del proceso de salud y enfermedad. Conclusión: El paradigma ofrecido por Meléis puede ser considerado un enfoque clave para emprender el proceso de cuidado de enfermería tendiente a apoyar a las personas con enfermedad crónica en el logro del automanejo.

Abstract Introduction: The experience of living with a chronic disease is not a simple task, since it requires tools that allow increasing the degree of awareness to face the needs and overcome challenges about the state of health and disease. In recent years, support for self-management has been established, with the aim of enhancing the skills of people with this type of condition. It is important to consider how the nursing discipline can contribute to achieve this. The aim of this paper is to reflect on Meléis' theory of transitions as a paradigm to support self-management in people with chronic conditions. Development: Meléis' theory of transitions establishes that people are in constant change, as occurs in the health-illness transition process. Receiving the diagnosis of a chronic disease involves a series of complex processes for the person, due to the multiplicity of variables involved. Meléis' theory provides guidelines to orient the nursing professional on key and interrelated elements, such as the previous conception of the nature of the transition and its conditions, which will serve for the planning of intervention modalities congruent with the person's experiences and their evaluation in the course of the health and disease process. Conclusion: The paradigm offered by Meléis can be considered a key approach to undertake the nursing care process aimed at supporting people with chronic illness in achieving self-management.

Aislación relativa comparada con absoluta en restauraciones de resina compuesta en pacientes con dentición permanente / Relative isolation versus rubber dam isolation for composite resin restorations in patients with permanent dentition

RESUMEN: Introducción: La técnica de restauración con resina compuesta requiere un adecuado control de la humedad durante el procedimiento. Para ello, puede realizarse aislación relativa (con tórulas de algodón y eyector de saliva) o aislación absoluta con goma dique de la o las piezas dentarias. Sin embargo, no está claro cuál de estos protocolos sería más efectivo. Métodos: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metaanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. Resultados y conclusiones: Identificamos tres revisiones sistemáticas que en conjunto incluyeron dos estudios primarios, todos correspondientes a ensayos aleatorizados. Concluimos que realizar aislación relativa comparado con aislación absoluta podría aumentar el riesgo de falla de restauración a los 6 meses, pero la certeza de la evidencia es baja. No es posible establecer con claridad si la aislación relativa disminuye el riesgo de falla de la restauración a 10 años, debido a que la certeza de la evidencia existente ha sido evaluada como muy baja. No se encontraron estudios que evaluaran los desenlaces caries secundaria, sensibilidad postoperatoria y tinción.

ABSTRACT: Introduction: Resin composite restorations technique requires effective control of moisture during the procedure. Isolation and moisture control can be performed by relative isolation (use of cotton rolls combined with aspiration by saliva ejector) or rubber dam isolation. However, there is uncertainty regarding which one of these protocols would be most beneficial. Methods: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. Results and conclusions: We identified three systematic reviews including two studies overall, of which all were randomized trials. We conclude that relative isolation may increase the risk of failure of the restorations at 6 months. We are uncertain whether relative reduces the risk of failure of the restorations at 10 years as the certainty of the evidence has been assessed as very low. No studies were found that looked at secondary caries, post-operative sensitivity or stained margins.

Infarto agudo al miocardio en el adulto mayor: Características clínicas, evolución hospitalaria y a 5 años plazo / Features of acute myocardial infarction among aged patients

Background: Among aged patients, acute myocardial infarction has more complications and there is a tendency to underuse proven treatments. Aim: To report the features of acute myocardial infarction among aged patients. Material and Methods: Analysis of a registry of patients with acute myocardial infarction admitted to a coronary unit. For the purposes of analysis, patients aged 65 years or more were selected. Follow up was made consulting medical records, calling patients by telephone or consulting death records at the National Identification Service. Results: A total of 1.358 patients were admitted in the study period with a diagnosis of acute myocardial infarction and 580 (43%) were aged 65years or more. On admission, this age group had a higher frequency of hemodynamic instability and anterior wall infarctions. Reperfusion therapy and beta blockers were used less commonly in this group. Hospital mortality among patients younger or older than 65 year was 8 and 25%, respectively (p < 0.01). Among aged patients, five years mortality was 33%. Conclusions: Among aged patients, acute myocardial infarction has a higher risk profile on admission, is usually undertreated and has higher mortality than younger subjects.

Angioplastía primaria en infarto agudo al miocardio en arteria coronaria derecha con origen anómalo: Caso clínico / Primary angioplasty for acute myocardial infarction with an anomalous origin of right coronary artery: Report of one case

Anomalous origin of coronary arteries is a rare anatomical defect and its association with acute myocardial infarction is unusual. We report a 58-year-old male with ST-Segment elevation. Myocardial infarction of the inferior wall caused by a total occlusion on the proximal third of an anomalous right coronary artery, that was effectively treated with primary angioplasty with stent placement. The patient had a favorable outcome and is asymptomatic after five years of follow up.

Terapia de reperfusión en infarto agudo al miocardio: Comparación entre trombolisis endovenosa y angioplastía coronaria / Angioplasty compared to thrombolysis as the initial reperfusion therapy in acute myocardial infarction

Background: Primary angioplasty is superior to intravenous thrombolysis as reperfusion therapy for acute myocardial infarction. Aim: To compare the results of available reperfusion strategies for initial management of acute myocardial infarction during hospitalization and 5 years follow up. Patients and Methods: Historical cohort study from a prospective registry of patients admitted with acute myocardial infarction to our center. Patients treated with primary angioplasty were identified and were then matched by age, sex and date of event with patients treated with throm-bolysis. The clinical outcomes were compared including hospitalization and 5-years follow-up. Results: From March 1993 to August 2001, 98 patients were treated with primary angioplasty and matched with 98 thrombolyzed patients. The groups were comparable. Compared to thrombolysis, angioplasty had a higher success rate (68 and 91% respectively), resulted in less complications and reduced mortality (11 and 2% respectively), required less revascularization procedures and shorter hospital stay (17 and 13 days, respectively). During the follow-up of survivors, no differences in events or additional mortality were detected at 1 or 5years. Conclusions: Primary angioplasty is superior as treatment in terms of achieving success and reducing mortality during hospitalization. Evolution after hospitalization is independent of initial therapy.

Hematoma subcapsular esplénico en paciente portador de rasgo falciforme / Sub capsular splenic hematoma in a sickle cell trait carrier. Case report

Drepanocytic anemia is an uncommon hereditary disease in Chile. The heterozygous state of drepanocytic anemia or "sickle trait" has a frequency of 8 percent among Afro-Americans. A small number of patients carrying hemoglobin S are homozygous, with clinical manifestations of hemolytic anemia and thrombotic disease. Sickle trait is usually asymptomatic. We report a 59-year-old male who presented an acute abdominal pain and dyspnea while staying at high altitude. Six days later, an angio CAT scan showed the presence of a subcapsular splenic hematoma that was managed conservatively. Sickle cell induction with sodium metabisulphite was positive. Hemoglobin electrophoresis confirmed the sickle trait.
