Soluciones hipertónicas en trauma craneoencefálico: revisión sistemática de la literatura

El traumatismo craneoencefálico, es la epidemia silenciosa de nuestra época, que genera gastos en salud, en países como Estados Unidos, cercanos a los 60 billones de dólares anuales, y cerca de 400 billones en rehabilitación de los discapacitados. El pilar del manejo médico del trauma craneoencefálico moderado o severo, es la osmoterapia, principalmente con sustancias como el manitol y las soluciones hipertónicas. Se realizó la revisión de 14 bases de datos, encontrando 4657754 artículos, quedando al final 40 artículos después de un análisis exhaustivo, que se relacionaban con el manejo de la hipertensión endocraneana y terapia osmótica. Resultados: Se compararon diferentes estudios, encontrando gran variabilidad estos, sin homogenización en los análisis estadísticos, y la poca rigurosidad no permitieron, la recolección de datos y la comparación entre los diferentes estudios, no permitió realizar el meta-análisis y por esto se decidió la realización de una revisión sistemática de la literatura. Se evidenció principalmente tres cosas: la primera es la poca rigurosidad con la que se realizan los estudios clínicos; la segunda, es que aún falta mucha más investigación principalmente, la presencia de estudios clínicos aleatorizados multicéntricos, que logren dar una sólida evidencia y que genere validez científica que se requiere, a pesar de la evidencia clara en la práctica clínica; la tercera es la seguridad para su uso, con poca presencia de complicaciones para las soluciones salinas hipertónicas.

Nivel de escolaridad y consumo de alcohol etílico, cannabinoides y solventes en Colombia año 2014

Introducción: El consumo de sustancias psicoactivas como problema de salud pública, debe ser abordado desde diferentes perspectivas. En la literatura se evidencia factores involucrados como, edad de inicio de consumo, información de riesgo, círculo social y antecedentes personales. Igualmente se ha mostrado la asociación con el deterioro de las capacidades de aprendizaje y la farmacodependencia. En este estudio se determinó la asociación del consumo de inhalantes, cannabis y etanol y el nivel de escolaridad alcanzado. Metodología: Estudio observacional transversal, cross sectional, de los casos reportados al sistema único de indicadores de consumo de sustancias psicoactivas en Colombia en 2014. Muestra 6804 casos. Se realizó análisis univariado y bivariado con valores de p, para significancia estadística. Resultados y discusión: Se identificó comportamiento epidemiológico similar, en concordancia con otros estudios, evidenciándose población entre los 15 y 35 años de edad (76,7%), predominantemente hombres (83,9%) y consumo principal de cannabis (43,9%) y alcohol (23,1%). Se determina asociación estadísticamente significativa entre el consumo de inhalantes, etanol y marihuana y la finalización incompleta de estudios de secundaria (p<0,005), el cannabis con asocio a culminación incompleta de estudios universitarios (p<0,005). Hay plausibilidad biológica y epidemiológica con los hallazgos del estudio y otros trabajos desarrollados con anterioridad.

Correlación y concordancia entre ecocardiografía y cateterismo cardiaco derecho para determinación de la presión sistólica de arteria pulmonar

Introducción. El cateterismo cardiaco derecho representa el estándar de referencia para el diagnóstico de hipertensión pulmonar, sin embargo el rendimiento de la ecocardiografía como estudio inicial ha mostrado buena correlación con las variables medidas por cateterismo. El presente estudio pretende describir el grado de correlación y concordancia entre la ecocardiografía y el cateterismo cardiaco derecho para la medición de la presión sistólica de la arteria pulmonar. Materiales y métodos. Se realizó un estudio observacional retrospectivo de los pacientes sometidos a cateterismo cardiaco derecho entre los años 2009 a 2014 y se compararon con los datos de ecocardiograma más cercano a este cateterismo, teniendo en cuenta la presión sistólica de la arteria pulmonar (PSAP) en las dos modalidades diagnósticas mediante correlación y concordancia estadística según los coeficientes de Pearson y el índice de Lin respectivamente. Resultados. Se recolectaron un total de 169 pacientes con un índice de correlación (r) obtenido para la medición de PSAP del total de la muestra de 0.73 p < 0.0001 mostrando un grado de correlación alto para toda la muestra evaluada. El análisis de concordancia obtenido para toda la población a partir del índice de Lin fue de 0.71 lo que determinó una pobre concordancia. Discusión. Se encontró buena correlación entre ecocardiografía y cateterismo cardiaco derecho para la medición de la PSAP, sin embargo la concordancia entre los métodos diagnósticos es pobre, por tanto el ecocardiograma no reemplaza al cateterismo cardiaco derecho como estudio de elección para diagnóstico y seguimiento de pacientes con hipertensión pulmonar.

Asma ocupacional en peluquería: una revisión de la literatura

Este artículo pretende realizar una revisión de la literatura vigente acerca del asma ocupacional secundaria a la exposición de los factores de riesgo identificados en peluquería. Se realizó una búsqueda sistemática en las bases de datos PubMed y Cochrane de artículos de revistas indexadas con las palabras claves “Asthma occupational, hairdressers, hairdresser, work related asthma”. Aplicando los criterios de selección descritos, se revisaron 26 artículos en total donde se incluían reportes de casos, estudios de prevalencia, incidencia, corte transversa y revisiones, abarcando principalmente los temas de epidemiologia, fisiopatología, diagnóstico y prevención. Se agruparon según la metodología PRISMA para su respectiva comparación. Se concluyó que a pesar de la importancia de esta patología en el sector de peluquería, existen factores asociados como la informalidad del sector, la falta de estudios de investigación originales de cohorte o el desconocimiento de un protocolo claro de diagnóstico en este tipo de trabajadores, que limitan datos concluyentes acerca de la misma. Sin embargo, la mayoría de los autores concluye la relación entre la patología y la labor de peluquería, así falte esclarecer los mecanismos fisiopatológicos relacionados con los alérgenos identificados.

PINCER trial: a cluster randomised trial comparing the effectiveness and cost-effectiveness of a pharmacist-led IT-based intervention with simple feedback in reducing rates of clinically important errors in medicines management in general practices

Background: Medication errors in general practice are an important source of potentially preventable morbidity and mortality. Building on previous descriptive, qualitative and pilot work, we sought to investigate the effectiveness, cost-effectiveness and likely generalisability of a complex pharm acist-led IT-based intervention aiming to improve prescribing safety in general practice. Objectives: We sought to: • Test the hypothesis that a pharmacist-led IT-based complex intervention using educational outreach and practical support is more effective than simple feedback in reducing the proportion of patients at risk from errors in prescribing and medicines management in general practice. • Conduct an economic evaluation of the cost per error avoided, from the perspective of the National Health Service (NHS). • Analyse data recorded by pharmacists, summarising the proportions of patients judged to be at clinical risk, the actions recommended by pharmacists, and actions completed in the practices. • Explore the views and experiences of healthcare professionals and NHS managers concerning the intervention; investigate potential explanations for the observed effects, and inform decisions on the future roll-out of the pharmacist-led intervention • Examine secular trends in the outcome measures of interest allowing for informal comparison between trial practices and practices that did not participate in the trial contributing to the QRESEARCH database. Methods Two-arm cluster randomised controlled trial of 72 English general practices with embedded economic analysis and longitudinal descriptive and qualitative analysis. Informal comparison of the trial findings with a national descriptive study investigating secular trends undertaken using data from practices contributing to the QRESEARCH database. The main outcomes of interest were prescribing errors and medication monitoring errors at six- and 12-months following the intervention. Results: Participants in the pharmacist intervention arm practices were significantly less likely to have been prescribed a non-selective NSAID without a proton pump inhibitor (PPI) if they had a history of peptic ulcer (OR 0.58, 95%CI 0.38, 0.89), to have been prescribed a beta-blocker if they had asthma (OR 0.73, 95% CI 0.58, 0.91) or (in those aged 75 years and older) to have been prescribed an ACE inhibitor or diuretic without a measurement of urea and electrolytes in the last 15 months (OR 0.51, 95% CI 0.34, 0.78). The economic analysis suggests that the PINCER pharmacist intervention has 95% probability of being cost effective if the decision-maker’s ceiling willingness to pay reaches £75 (6 months) or £85 (12 months) per error avoided. The intervention addressed an issue that was important to professionals and their teams and was delivered in a way that was acceptable to practices with minimum disruption of normal work processes. Comparison of the trial findings with changes seen in QRESEARCH practices indicated that any reductions achieved in the simple feedback arm were likely, in the main, to have been related to secular trends rather than the intervention. Conclusions Compared with simple feedback, the pharmacist-led intervention resulted in reductions in proportions of patients at risk of prescribing and monitoring errors for the primary outcome measures and the composite secondary outcome measures at six-months and (with the exception of the NSAID/peptic ulcer outcome measure) 12-months post-intervention. The intervention is acceptable to pharmacists and practices, and is likely to be seen as costeffective by decision makers.

Avoiding the Fog of Crisis: A Protocol for the Proper Domestic Use of the Military

Failure to contemplate and define an appropriate role for the armed forces of the national government in domestic crises of this sort is a serious problem. It is all the more serious now as these potential crises seem to multiply in character and scope. This thesis will explore the history of this problem and its recent implications. It will argue the need for a comprehensive, operational framework, codified in law, which defines the various alternative uses of all emergency services, both civilian and military, and is applicable to “all hazards.” I will attempt to provide a blue-print for what such a framework should look like.

Supervision, control and regulation of land transport

The first Latin American meeting of bodies responsible for the supervision, control and regulation of land transport, organized jointly by the Economic Commission for Latin America and the Caribbean (ECLAC) and the National Transport Regulation Commission of Argentina (CNRT), was held in Buenos Aires from 5 to 7 November 1997. Representatives of public- and private-sector bodies connected with land transport in Latin America, the United States of America and Europe took part in the meeting, in an atmosphere which was highly interactive owing to the numerous questions asked and the enriching discussions.

Aplicação dos princípios de radioproteção em medicina nuclear

The Nuclear Medicine is a medical specialty which uses different radioisotopes for diagnostic and therapeutic purposes. The isotopes are radioactive elements which are administered in vivo and present distribution to specific organs or cell types. The knowledge of radioactivity and notions related to ionizing radiation allow to contextualize the radiological protection measures to be taken in Nuclear Medicine. So it is possible to minimize unnecessary exposure to patients, the public, and individuals occupationally exposed and the environmental. For this it is necessary to relate the physical and technological bases apply to this mode with the standards established by regulatory agencies, including the CNEN (National Nuclear Energy Commission) and ANVISA (National Agency for Sanitary Vigilance). In this scenario, it is important that the theoretical endorse the activities which are periodically audited for verification of compliance with the standards that aim to radioprotection. One role of the Medical Physicist in these services is, therefore, act as Radiation Protection Supervisor exerting numerous activities and ensuring compliance with these standards. In this context the stage in the area of Nuclear Medicine was developed in many customers of the enterprise Rad Dimenstein & Associados LTDA, among them the hospitals Israelita Albert Einstein (HIAE), Nossa Senhora de Lourdes (HNSL), Santa Paula (HSP), Cruz Azul (CRAZ), Grupo Fleury, among other clinics. Following the routine and then carrying out various activities pertaining to the Medical Physicist in the area, it was noted that the measures and actions are extremely effective and fundamental in terms of radiological protection

Gamma Irradiation of in-Shell and Blanched Peanuts Protects against Mycotoxic Fungi and Retains Their Nutraceutical Components during Long-Term Storage

Peanut samples were irradiated (0.0, 5.2, 7.2 or 10.0 kGy), stored for a year (room temperature) and examined every three months. Mycotoxic fungi (MF) were detected in non-irradiated blanched peanuts. A dose of 5.2 kGy was found suitable to prevent MF growth in blanched samples. No MF was detected in in-shell peanuts, with or without irradiation. The colors of the control in-shell and blanched samples were, respectively, 44.72 and 60.21 (L *); 25.20 and 20.38 (Chroma); 53.05 and 86.46 (degrees Hue). The water activities (Aw) were 0.673 and 0.425. The corresponding fatty acids were 13.33% and 12.14% (C16:0), 44.94% and 44.92% (C18:1,omega 9) and 37.10% and 37.63% (C18: 2,omega 6). The total phenolics (TP) were 4.62 and 2.52 mg GAE/g, with antioxidant activities (AA) of 16.97 and 10.36 mu mol TEAC/g. Storage time negatively correlated with Aw (in-shell peanuts) or L *, linoleic acid, TP and AA (in-shell and blanched peanuts) but positively correlated with Aw (blanched peanuts), and with oleic acid (in-shell and blanched peanuts). Irradiation positively correlated with antioxidant activity (blanched peanuts). No correlation was found between irradiation and AA (in-shell samples) or fatty acids and TP (in-shell and blanched peanuts). Irradiation protected against MF and retained both the polyunsaturated fatty acids and polyphenols in the samples.
