Experiencias sobre la implementación del Expediente Clínico Electrónico / Experiences on the implementation of the Electronic Medical Record

Resumen Introducción. Un elemento de la e-salud que ha cobrado gran relevancia es el Expediente Clínico Electrónico (ECE) ya que es un medio para lograr mejores resultados en la práctica médica. Al momento, han sido pocas las investigaciones que se han centrado en analizar e identificar la situación de esta estrategia en el mundo. Por ello, el objetivo de esta investigación es analizar el panorama actual del ECE en diversos países considerando las ventajas, desventajas, desafíos y factores de éxito en su implementación. Metodología: Se realizó una revisión de la literatura existente sobre el ECE en base de datos especializadas. Para obtener estos estudios se utilizó la base de datos de scopus y sciencedirect , utilizando palabras de búsqueda como como registro electrónico de salud, registro médico electrónico o expediente clínico electrónico; se seleccionaron solamente aquellos estudios con un alto factor de impacto, mismo que se refiere al número de veces que se hayan citado los artículos consultados. Se seleccionaron y analizaron 64 estudios académicos. Resultados. Se encontró que aún existen importantes desafíos y desventajas en la implementación del ECE como la interoperabilidad semántica y el estrés laboral que genera en los usuarios este sistema. Conclusiones. Existen cuestiones importantes que aún quedan por resolver para una implementación eficaz del ECE. Es necesario integrar a todos los involucrados en el proceso de cambio, así como establecer las medidas de seguridad necesarias para garantizar la privacidad de la información.

Abstract Introduction. An element of e-health that has gained great relevance is the Electronic Medical Record (ECE) since it is a means to achieve better results in medical practice. At the moment, few investigations have focused on analyzing and identifying the situation of this strategy in the world. Therefore, the objective of this research is to analyze the current panorama of ECE in various countries considering the advantages, disadvantages, challenges and success factors in its implementation. Methodology. A review of the existing literature on ECE was carried out in specialized databases. To obtain these studies, the scopus and sciencedirect databases were used, using search words such as "electronic health record", "electronic medical record" or "electronic medical record"; Only those studies with a high impact factor were selected, which refers to the number of times the articles consulted have been cited. 64 academic studies were selected and analyzed. Results. It was found that there are still important challenges and disadvantages in the implementation of ECE such as semantic interoperability and the work stress that this system generates in users. Conclusions. There are important issues that remain to be resolved in the effective implementation of the ECE. It is necessary to integrate all those involved in the change process as well as to establish the necessary security measures to guarantee the privacy of the information.

Effects of post-mastectomy radiation therapy on T1-2 stage and one to three positive lymph node breast cancer patients with differ-ent risk factors / 中国肿瘤临床

Objective:To retrospectively evaluate the prognostic risk factors of T1-2 stage breast cancer patients with one to three positive node(s) and their effects on the benefits of post-mastectomy radiation therapy (PMRT). Methods:We retrospectively analyzed 457 breast cancer patients with T1-2 stage and one to three positive axillary lymph nodes treated in our hospital between 2000 and 2002. The independent prognostic factors of the patients were calculated by the Cox proportional hazards model. The patients were fur-ther classified into high-risk and low-risk subgroups according to the risk factors to explore the benefit of PMRT on the prognosis of dif-ferent subgroups using survival analysis. Results:PMRT was not an independent beneficial factor of overall survival (OS) (HR=0.949;CI:0.435-2.074;P=0.896) or loco-regional recurrent free survival (LRRFS) (HR=0.611;CI:0.231-1.614;P=0.320) in all patients. Ex-tracapsular extension (ECE) and pathological grades were independent prognostic risk factors, and the benefits of PMRT were signifi-cantly different on the prognosis of high-risk subgroup patients (group ECE+OS:P=0.020, LRRFS:P=0.014;group GradeⅢOS:P=0.002, LRRFS:P<0.001). Meanwhile, PMRT failed to prolong the OS and LRRFS of low-risk subgroup patients (group ECE+OS:P=0.353, LRRFS:P=0.796;group GradeⅠtoⅡOS:P=0.267, LRRFS:P=0.589). Conclusion:ECE and gradeⅢwere the independent risk factors of death and loco-regional recurrence in the T1-2 breast cancer patients with one to three positive lymph node(s). PMRT was an effective adjuvant therapy to improve the prognosis of patients with high-risk factors. However, the benefit of PMRT had no sig-nificance in patients with ECE-or gradeⅠ-Ⅱ.

Effects of triptolide on endothelin-1 and its gene expression in lung of asthmatic guinea-pigs / 中国药理学通报

AIM To explore the effects of trip-tolide on endothelin-1 and its gene expression in lung of asthmatic guinea-pigs. METHODS The contents of ET-1 in lung of asthmatic guinea-pigs were measured with radioimmunoassay, and the expressions of ET-1, ETA, ETB and ECEmRNA with reverse transcription DNA polymerase chain reaction (RT-PCR). RESULTS 0 All of the indexes were increased after guinea-pigs were induced asthma. At the 4th hour after first induction of asthma, ET-1 reached the top, but at the 2rd hour, ET-1mRNA, ETAmRNA and ECEmRNA were markedly higher than control group (P
