Evaluación e intervención interdisciplinaria del dolor en Unidades de Cuidado Intensivo

El dolor es un problema importante para los pacientes hospitalizados en las UCI porque genera malestar y distrés. Además, la investigación ha demostrado que en algunos pacientes críticos el dolor agudo puede persistir después de alta y convertirse en crónico. La gestión eficaz del dolor en pacientes críticos requiere un enfoque interdisciplinario, que incorpore la visión y trabajo de expertos que representan una amplia variedad de especialidades clínicas. Así, la utilización de la intervención psicológica en el tratamiento del dolor es una parte integral de un enfoque global. Basado en una revisión de la evidencia científica, se identifican y señalan: (1) los tipos de dolor más comunes; (2) las características del dolor; (3) las patologías más frecuentes asociadas con la presencia de dolor; (4) los procedimientos que generan dolor en la UCI; (5) los métodos de evaluación del dolor; (6) la intervención del mismo y; (7) la contribución del psicólogo en la evaluación y manejo del dolor con el paciente, los familiares y los profesionales de la salud. La revisión realizada indica que los procesos psicológicos influyen tanto en la experiencia del dolor como en los resultados del tratamiento, por lo tanto la integración de los principios psicológicos en el tratamiento del dolor parecen tener potencial mejora de los resultados beneficiando la salud del paciente.

Preliminary Study on Safety Conditions in Health Workers Exposed to Antineoplastic Drugs

A study was done to establish work practices and preventive measures for nurses handling antineoplasticdrugs (AND) and to determine the risk of developing AND-related symptoms. A descriptive cross sectional study was made. Workers from 5 health centers in Valencia, Venezuela, were selected. Demography, occupational and clinical history, shift, work practices, safety precautions, antineoplastic drugs used, residues disposal and life styles were obtained via a questionnaire. Most prevalent symptoms were adjusted for age, shift, and smoking. Age was significant for cough and dizziness; smoking was significant for abdomipo seleccionado de trabajadores que manejan FAN en cinco centros de salud de la ciudad de Valencia, Venezuela, con el propósito de evaluar de forma preliminar su riesgo potencial de desarrollar signos-síntomas derivados de este oficio; a su vez, establecer si existe la necesidad de continuar con una evaluación más profunda que permita hacer recomendaciones concluyentes para evitar sus efectos adversos. Metodología La población estuvo constituida por el personal de las unidades de oncología de cinco centros de salud de la ciudad de Valencia, Venezuela. La muestra la conformaron veinte trabajadores que pertenecen a dichos centros. La participación fue voluntaria y mediante firma de una carta de consentimiento. Recolección de datos Se realizó una entrevista a cada participante con información que hizo referencia a datos demográficos, historia ocupacional, turnos de trabajo, entrenamiento en medidas de seguridad para el manejo de este tipo de fármacos, actividades que realizan, uso de equipos de protección personal (EPP), sitio de manipulación de nal pain and shift was significant for nausea and cough. Nauseas were the most prevalent symptom (55%). Dizziness was directly associated with use of gowns and inversely half-face respirator. None of the studied centers had satisfactory working conditions. A follow up study should be made including physical exam and environmental and biological monitoring.

Medical Student’s Use of Time During Clinical Clerkships and the Credits Based System

Introduction: Comprehensive undergraduate education in clinical sciences is grounded on activities developed during clerkships. To implement the credits system we must know how these experiences take place. Objectives: to describe how students spend time in clerkships, how they assess the educative value of activities and the enjoyment it provides. Method: We distributed a form to a random clustered sample of a 100 students coursing clinical sciences, designed to record the time spent, and to assess the educative value and the grade of enjoyment of the activities in clerkship during a week. Data were registered and analyzed on Excel® 98 and SPSS. Results: mean time spent by students in clerkship activities on a day were 10.8 hours. Of those, 7.3 hours (69%) were spent in formal education activities. Patient care activities with teachers occupied the major proportion of time (15.4%). Of the teaching and learning activities in a week, 28 hours (56%) were spent in patient care activities and 22.4 hours (44.5%) were used in independent academic work. The time spent in teaching and learning activities correspond to 19 credits of a semester of 18 weeks. The activities assessed as having the major educational value were homework activities (4.6) and formal education activities (4.5). The graded as most enjoyable were extracurricular activities, formal educational activities and independent academic work. Conclusion: our students spend more time in activities with patients than the reported in literature. The attending workload of our students is greater than the one reported in similar studies.

Occupational therapy and its relevance in social projects. relationships, learning and opportunities: collection of experiences of University of Alberta Mscot students in Bogotá, Colombia

Occupational therapists are equipped to promote wellbeing through occupation and to enable participation and meaningful engagement of people in their social and physical environments (WFOT, 2012). As such, the role of the occupational therapists is profoundly linked to the social, cultural and environmental characteristics of the contexts in which occupations take place. The central role that context plays in occupational performance creates an interesting dichotomy for the occupational therapist: on one hand, a profound understanding of cultural and social factors is required from the Occupational Therapy (OT) in order to develop a meaningful and successful collaboration with the person; on the other hand, the ability of the occupational therapists to recognize and explore the contextual factor of an occupation-person dyad transcends cultural and spatial barriers. As a result, occupational therapists are equipped to engage in international collaboration and practice, and as such face unique and enriching challenges. International fieldwork experiences have become a tool through which occupational therapists in training can develop the critical skills for understanding the impact of cultural and social factors on occupation. An OT student in an international fieldwork experience faces numerous challenges in leading a process that is both relevant and respectful to the characteristics of the local context: language, cultural perceptions of occupation and personhood, religious backgrounds, health care access, etc. These challenges stand out as ethical considerations that must be considered when navigating an international fieldwork experience (AOTA, 2009). For more than five years now, the Faculty of Rehabilitation Medicine (FRM) of the University of Alberta (UoFA) and the School of Medicine and Health Sciences at the Universidad del Rosario (UR), Bogota, Colombia, have sustained a productive and meaningful international collaboration. This collaboration includes a visit by Dr. Albert Cook, professor of the FRM and former dean, to the UR as the main guest speaker in the International Congress of Technologies for Disability Support (IBERDISCAP) in 2008. Furthermore, Dr. Cook was a speaker in the research seminar of the Assistive Technology Research Group of the Universidad del Rosario. Following Dr. Cook’s visit, Professors Liliana Álvarez and Adriana Ríos travelled to Edmonton and initiated collaboration with the FRM, resulting in the signing of an agreement between the FRM and the UR in 2009, agreement that has been maintained to this day. The main goal of this agreement is to increase academic and cultural cooperation between the UR and the UofA. Other activities have included the cooperation between Dr. Kim Adams (who has largely maintained interest and effort in supporting the capacity building of the UR rehabilitation programs in coordinating the provision of research placement opportunities for UR students at the UofA), an Assistive Technology course for clinicians and students led by Dr. Adams, and a research project that researched the use of basic cell phones to provide social interaction and health information access for people with disabilities in a low-income community in Colombia (led by Tim Barlott, OT, MSc, under the supervision of Dr. Adams). Since the beginning, the occupational therapy programs of the Universidad del Rosario and the University of Alberta have promoted this collaboration and have strived to engage in interactions that provide further development opportunities for students and staff. As part of this process, the international placement experience of UofA OT students was born under the leadership of: Claudia Rozo, OT program director at UR, placement and academic leadership of Elvis Castro and Angélica Monsalve, professors of the occupational therapy program at UR; and Dr. Lili Liu, OT department director at UofA, Cori Schmitz, Academic coordinator of clinical education at the UofA; and Tim Barlott and Liliana Álvarez leading the international and cross-cultural aspect of this collaboration.This publication summarizes and illustrates the process of international placement in community settings in Colombia, undertaken by occupational therapy students of the University of Alberta. It is our hope that this document can provide and document the ethical considerations of international fieldwork experience, the special characteristics of communities and the ways in which cultural and social competences are developed and help international students navigate the international setting. We also hope that this document will stimulate discussion among professional and academic communities about the importance and richness of international placement experiences and encourage staff and students to articulate their daily efforts with the global occupational therapy agenda.

Terapias no farmacológicas en el manejo del dolor en neonatos pretérmino. revisión sistemática de la literatura

Antecedentes El dolor en neonatos ha sido un problema poco explorado. Se ha propuesto el uso de las terapias no farmacológicas para su tratamiento, sin embargo existen pocas aproximaciones sistemáticas para la evaluación de su eficacia. Objetivos Determinar la eficacia de las terapias no farmacológicas en el manejo del dolor en neonatos pretérmino a través de una revisión sistemática. Metodología Se realizó una revisión sistemática de la literatura para evaluar la eficacia de las terapias no farmacológicas en el manejo del dolor en el recién nacido petérmino. La búsqueda se realizó a través de las bases de datos Embase, Cochrane, Bireme y Embase. Se identificaron estudios publicados inglés y español. Se realizó un análisis cualitativo y cuantitativo. Resultados Se incluyeron 10 ensayos clínicos. La solución de sacarosa administrada por vía oral mostró reducir la intensidad del dolor en el recién nacido. La intubación y toma de muestras facilitada por el cuidador mostró también reducir la intensidad del dolor. Conclusión Se recomienda la administración solución de sacarosa y acompañamiento del cuidador durante los procedimientos como medidas para reducir el dolor en el recién nacido pretérmino.

The use of insect cells to identify potent and selective inhibitors of the replication of the Dengue and Chikungunya viruses and unravel their molecular mechanism of action

Dengue and Chikungunya viruses cause the most important arthropod-borne viral infections for humans. These viruses are predominant in tropical and subtropical regions. In addition, these viruses are predominant in tropical and subtropical regions. Dengue mortality rate is around 1.2 to 3.5% and deaths due to chikungunya fever are around 1 in 1000; however, half of chikungunya-infected patients evolve into a chronic state that can persist for months up to years. There are no antiviral drugs available for DENV and CHIKV treatment and prevention. Moreover, vector control strategies have failed so far. Thus, the development of potent inhibitors for a broad spectrum of RNA viruses is urgently needed. We established and characterized a new embryonic insect cell line from Culex quinquefasciatus mosquito. Also we established the flaviviruses and alphavirus replication, both in C6/36 and Lulo insect cell lines, as well as in Vero cell line. In addition we carried out a reference compound library and reference panel of assays and data for DENV, which provides a benchmark for further studies. During this study, a panel of 9 antiviral molecules, with proven in vitro anti-dengue virus activity and that act at different stages of the DENV life cycle, was selected. Finally, Favipiravir or T-705, was identified as inhibitor in vitro and in vivo of alphaviruses and the mutation K291R in nsP4, which is responsible of the polymerase activity, was found as the mode of action in CHIKV. Interestingly, lysine in motif F1 is also highly conserved in positive-stranded RNA viruses and this might explain the broad spectrum of T-705 antiviral activity.
