Abstract: introduction: haemodialysis (hd) lines are traditionally primed with sodium heparin and saline solution, which entails the haemorrhagic risk associated to the passing of heparin into the blood. aim: to compare hd dialyser priming with and without sodium heparin, in terms of coagulation, dialytic efficacy, and economic efficacy. material and method: a randomized, prospective studio of 3482 sessions with 109 hd patients (x 66.8±15 years, 40% women, 44% diabetic, 45% with high-flow tunnelled catheter, 50% native iaf, 5% prosthetic iaf). 1827 sessions carried out with fifty-nine patients were included in the control group (primed with saline solution + sodium heparin) and 1455 sessions with patients in the study group (primed with saline solution). the monitoring period was 5 months. variables related to the coagulation of the circuit and the efficacy of the dialysis were analysed: selected blood flow (qb) and effective qb, final status of the dialyser, number of changes of dialyser, number of changes of the arterial line, number of changes of the venous, average kt/hour measured by ionic dialysance and heparinization of the circuit. the efficacy in economic terms was also studied. results: there are no significant differences in the results related to coagulation and efficacy of the dialysis obtained in both groups, except x of heparin with low molecular weight (2476±1089 iu in the study group compared to 2854±1414 iu in the control group). priming without heparin represents a saving of 0.50 € per session. conclusions: priming with saline solution does not affect the hd dose, and does not entail a greater risk of coagulation of the system compared to a priming solution to which heparin has been added, avoids the risk of heparin passing into the bloodstream, reduces handling in the connection protocols and reduces costs.

Revista Cubana de Pediatr?-a , 2001,
Abstract: La miastenia gravis es una entidad clínica de origen autoinmune, cuya terapia habitual se realiza con drogas anticolinérgicas, la timectomía o la terapia con esteroides. Fue el objetivo del trabajo el conocer los cambios que se producen en el tama o del área tímica, con el uso de esteroides, en una paciente de 2 a os de edad, que presentaba miastenia gravis juvenil, con una hiperplasia tímica. Esta glándula alcanzó un área máxima de 1 928 mm. Con el uso de la prednisona a 60 mg por semanas se produjo una timectomía medicamentosa, con la reducción del área tímica a 439 mm y remisión total de la sintomatología. Se realizaron las mediciones periódicamente durante un a o de los cambios del área de este órgano. No se produjeron recaídas de la enfermedad de base. La ultrasonografía demostró ser un método útil, por ser rápido, barato y no invasiva y permite un ajuste adecuado de la dosis de esteroides que se administrará. Myasthenia gravis is a clinical agent of autoimmune origin, whose habitual therapy includes anticholinergic drugs, thymectomy, or therapy with steroids. The objective of this paper was to know the changes that occur in the size of the thymic area in a 2-year-old patient with juvenile myasthenia gravis and with thymic hyperplasia. This gland reached a maximum area of 1 928 mm and with the use of 60 mg of prednisone per week a medicamentosus thymectomy was performed with the reduction of the thymic area to 439 mm and total remission of the symptomatology. The changes of the area of this organ were periodically measured during a year. There were no relapses of the base disease. The ultrasonography proved to be a useful method, since it is fast, cheap and noninvasive and allows an adequate control of the steroids dose to be administered.

Abstract: Introducción: las enfermedades trasmitidas por los alimentos (ETA) constituyen el problema de salud pública más extendido en el mundo, por lo que es necesario mantener una vigilancia epidemiológica de estas para aplicar medidas oportunas que permitan su control y prevención. Objetivo: elevar el nivel de conocimiento sobre las enfermedades transmitidas por alimentos, en estudiantes de la Facultad de Tecnología de la Salud en la provincia de Camagüey. Métodos: se realizó un estudio experimental de intervención educativa en la Facultad de Tecnología de la Salud en la Provincia de Camagüey desde el 31 de diciembre de 2008 al 30 de abril de 2009. Para la ejecución del estudio en una primera etapa se estableció la comunicación con los estudiantes, lo que quedó validado a través del consentimiento informado. El universo fue de 421 jóvenes de los cuales se seleccionó una muestra (n = 110 estudiantes), a través de un muestreo aleatorio simple, a los que se les aplicó un cuestionario. Toda la información se conservó bajo los principios de máxima confiabilidad. Se empleó la técnica de McNemar para la validación estadística de las tablas sobre el nivel de conocimiento, con el fin de mostrar los cambios ocurridos antes y después, con un nivel de significación de p < 0,05. Resultados: el grupo de edad que predominó fue el de 17 a 21 a os del sexo femenino para el 53,5 %. Antes de la intervención los estudiantes tenían conocimientos escasos sobre qué son las enfermedades transmitidas por alimentos (47,2 %), así como los agentes causales y los métodos que podrían tomarse para disminuir o erradicar las enfermedades trasmitidas por los alimentos. Conclusiones: la intervención educativa aplicada demuestra ser eficaz; por tanto, creemos necesario extender las intervenciones educativas a las instituciones escolares de salud en las cuales las enfermedades de transmisión por alimentos constituyen un riesgo para la salud de los propios estudiantes y trabajadores. Introduction: Food-borne diseases (FBD) are the most widely spread public health problem worldwide. Therefore, it is necessary to keep them under epidemiological surveillance in order to apply timely measures allowing their control and prevention. Objective: Expand the knowledge of food-borne diseases among students from the School of Health Technology in the province of Camagüey. Methods: An educational intervention experimental study was conducted at the School of Health Technology in the province of Camagüey from 31 December 2008 to 30 April 2009. In the first stage of the study, communication was established with t

Abstract: An analysis of chemical composition data of particulate matter samples (TSP, PM10 and PM2.5) collected from 2002 to 2008 in the North Atlantic free troposphere at the Iza a Global Atmospheric Watch (GAW) observatory (Tenerife, Canary Islands) shows that desert dust is very frequently mixed with particulate pollutants in the Saharan Air Layer (SAL). The study of this data set with Median Concentrations At Receptor (MCAR) plots allowed the identification of the potential source regions of the dust and particulate pollutants. Areas located at the south of the southern slope of the Atlas mountains emerge as the most frequent source of the soil desert dust advected to the northern edge of the SAL in summer. Industrial emissions occurring in Northern Algeria, Eastern Algeria, Tunisia and the Atlantic coast of Morocco appear as the most important source of the nitrate, ammonium and a fraction of sulphate (at least 60 % of the sulphate <10 μm transported from some regions) observed in the SAL. These emissions are mostly linked to crude oil refineries, phosphate-based fertilizer industry and power plants. Although desert dust emissions appear as the most frequent source of the phosphorous observed in the SAL, high P concentrations are observed when the SAL is affected by emissions from open mines of phosphate and phosphate based fertilizer industry. The results also show that a significant fraction of the sulphate (up to 90 % of sulphate <10 μm transported from some regions) observed in the SAL may be influenced by soil emissions of evaporite minerals in well defined regions where dry saline lakes (chotts) are present. These interpretations of the MCAR plots are consistent with the results obtained with the Positive Matrix Factorization (PMF2) receptor modelling. The results of this study show that North African industrial pollutants may be mixed with desert dust and exported to the North Atlantic in the Saharan Air Layer.
