RESUMEN

Introducción: La ciencia argentina ha jugado un papel importante en el estudio de la presión arterial. Sin embargo, esta producción científica no ha sido caracterizada. Nos propusimos: 1) analizar la contribución de las publicaciones científicas indizadas en MEDLINE de autores con filiación argentina en el campo de la presión arterial e hipertensión arterial en los últimos 50 años, y 2) determinar las características de las revistas científicas en las cuales se publicaron. Métodos: Se analizaron cuantitativa y cualitativamente 831 publicaciones indizadas en MEDLINE (periodo 1966-2017) de autores de Argentina. Resultados: El número de publicaciones se incrementaron 5,4 veces en los últimos 20 años. El 80% de las publicaciones fueron manuscritos originales y el 15% revisiones. El 65% de las publicaciones abordaron la investigación clínica y el 33% la investigación básica. El promedio de autores por trabajo fue de 6 (89% como primer autor), el 74% pertenecían a instituciones públicas. Las investigaciones se publicaron en revistas editadas en EE. UU. (36%), Reino Unido (27%), Holanda (12%), España (6%) y Argentina (4%). El 18% de las publicaciones fue en revistas con factor impacto >3,88 (primer cuartil). Solo el 5% accedieron a revistas con factor ≥10. El índice SJR promedio fue 1,66. Conclusiones: La producción científica Argentina en MEDLINE en el campo de la presión arterial e hipertensión arterial presentó un crecimiento constante. La gran mayoría son investigaciones originales, dirigidas por investigadores con filiación en instituciones públicas. Mayormente se accede a revistas extranjeras con aceptables índices de calidad

Introduction: Argentine science has played an important role in the study of blood pressure. However, this scientific production has not been classified. We set out (1) to analyse the contribution of scientific publications indexed in MEDLINE of authors with Argentinean academic affiliation in the field of blood pressure and hypertension in the last 50 years and, (2) determine the characteristics of the scientific journals in which they were published. Methods: The 831 indexed MEDLINE publications by authors from Argentina were analysed quantitatively and qualitatively (period 1966-2017). Results: The number of publications has increased 5.4 times in the last 20 years. Eighty percent of the publications were original manuscripts and 15% reviews. Sixty-five percent of the publications addressed clinical research, 33% basic research. The average authors per paper was 6 (89% as first author), 74% belonged to public institutions. The research was published in journals published in the United States (36%), the United Kingdom (27%), the Netherlands (12%), Spain (6%) and Argentina (4%). Eighteen percent of the publications were in journals with impact factor >3.88 (first quartile). Only 5% accessed journals with a factor ≥10. The average SJR index was 1.66. Conclusions: Argentine scientific production in MEDLINE in the field of blood pressure and hypertension showed constant growth. The vast majority is original research, directed by researchers with affiliation to public institutions. Foreign journals are accessed in the main, with acceptable quality indexes

RESUMEN

Objetivos: Describir la calidad del sueño de los pacientes sometidos a cirugía cardiaca durante las dos primeras noches de postoperatorio e identificar algunos de los factores condicionantes del descanso nocturno de estos pacientes en la Unidad de Cuidados Intensivos. Método: Estudio descriptivo observacional basado en la aplicación del Cuestionario del Sueño de Richards-Campbell mediante un muestreo consecutivo de pacientes sometidos a cirugía cardiaca con ingreso en Unidad de Cuidados Intensivos. Simultáneamente se aplicó un cuestionario que evaluaba diferentes factores ambientales existentes en la unidad como posibles condicionantes del descanso nocturno. Se estudió la asociación entre el consumo de opiáceos y la calidad del sueño. Resultados: Muestra de 66 pacientes con edad media de 65±11,57 años, de los cuales el 73% eran hombres (N=48). El Cuestionario del Sueño de Richards-Campbell obtuvo una puntuación media de 50,33mm (1.a noche) y 53,30mm (2.a noche). Los principales factores perturbadores del sueño fueron el malestar con los diferentes dispositivos 30,91mm y el dolor 30,18mm. Los problemas generados por el ruido ambiental 27,5mm o bien a través de las voces de los profesionales 26,53mm también resultaron elementos de molestia nocturna. No se encontró asociación estadística entre el sueño y la distancia del box del paciente respecto al control de enfermería ni en relación con el consumo de analgésicos opiáceos. Conclusiones: La calidad del sueño durante las dos primeras noches de ingreso en Unidad de Cuidados Intensivos fue ‘regular’. Los factores ambientales que más condicionaron el descanso nocturno de los pacientes fueron el malestar, el dolor y el ruido ambiental (AU)

Objectives: To describe the quality of sleep of patients undergoing cardiac surgery during the first two nights following surgery and identify some of the factors conditioning the nightly rest of these patients in the Intensive Care Unit. Method: Observational descriptive study based on applying the Richards-Campbell Sleep Questionnaire through a consecutive sample of patients undergoing cardiac surgery with Intensive Care Unit admission. Simultaneously, a questionnaire assessing different environmental factors existing in the unit as possible conditioning of the night's rest was applied. The association between consumption of opioid and sleep quality was studied. Results: Sample of 66 patients with a mean age of 65±11.57 years, of which 73% were men (N=48). The Richards-Campbell sleep questionnaire garnered average scores of 50.33mm (1.st night) and 53.30mm (2.nd night). The main sleep disturbing factors were discomfort with the different devices, 30.91mm and pain, 30.18mm. The problems caused by environmental noise, 27.5mm or through the voices of the professionals, 26.53mm were also elements of nocturnal discomfort. No statistical association was found between sleep and the distance of the patient with respect to the nursing control area or related to opioid analgesics. Conclusions: The quality of sleep during the first two nights of Intensive Care Unit admission was ‘regular’. The environmental factors that conditioned the night-time rest of patients were discomfort, pain and ambient noise (AU)

RESUMEN

El dolor es uno de los principales síntomas referidos por los pacientes sometidos a cirugía cardiaca. Objetivos Describir el dolor y explicar la posible asociación entre determinadas variables sociodemográficas, psicológicas y biológicas de los pacientes sometidos a cirugía cardiaca con la intensidad de dolor durante el postoperatorio en UCI. Pacientes y método Estudio descriptivo longitudinal entre febrero de 2008 y enero de 2009 sobre pacientes sometidos a cirugía cardiaca con ingreso en la UCI del Hospital de Navarra previo consentimiento informado. Entrevista preoperatoria con registro de variables sociodemográficas, biológicas, psicológicas y de morbilidad. Dolor monitorizado durante las primeras 48 horas de estancia en UCI a través de la Escala Verbal Numérica (EVN) del dolor. Nivel de significación aceptado p<0,05.ResultadosMuestra de 69 pacientes con media de edad de 62 años; el 74%, hombres y el 26%, mujeres. Encontramos asociación estadística entre niveles de dolor postoperatorio superiores para las variables edad < 65 años, cirugía de revascularización con injerto de arteria mamaria interna y ansiedad preoperatoria. Existió un aumento significativo en el consumo analgésico para las variables renta > 1.400 euros/mes, cirugía de revascularización con injerto de arteria mamaria y ansiedad preoperatoria. Conclusiones El dolor postoperatorio tras cirugía cardiaca está sujeto a una gran variabilidad individual. En nuestro estudio, edad, cirugía de revascularización con injerto de arteria mamaria y ansiedad preoperatoria se mostraron como variables predictivas del dolor postoperatorio de los pacientes sometidos a cirugía cardiaca

Pain is one of the main symptoms reported by patients who have had heart surgery. Objectives To describe the pain and explain the possible association among demographics, psychological and biological variables of the patients subjected to heart surgery with pain intensity during the postoperative in the ICU. Patients and method A descriptive, longitudinal study conducted between February 2008 and January 2009 on patients subjected to heart surgery with admission to the ICU of the Hospital of Navarra was conducted. A preoperatory interview was made with registration of sociodemographic, biological and psychological variables. Pain intensity was monitored during the first 48hours of ICU stay with the Verbal Numeric Scale (VNS) of pain. Accepted level of significance was p<0.05.ResultsA sample of 69 patients with mean age of 62, 26% women and 74% men was included. A superior statistical association was found between postoperative pain levels for age<65 years, bypass grafting with internal mammary artery and preoperatory anxiety variables.
