A detailed study of Seabra's lipasic reagent for the diagnostic of tuberculosis has been made. Substrate. The oily emulsion of cotton seed oil containing gum as dispersing agent, presented a pH variation to the ampoulles examined. In these belonging to the same cartoon as well as in those from different cartoons the values obtained electrometrically ranged from pH 5.8-6.4 (Table I). These variations lead us to presuppose: 1) instability of the oily emulsion in gum; 2) spontaneous hydrolysis of the oil; 3) different batches or technique of the oil extraction, or different sources. Buffer: The same variability observed with substrate was found for the buffer. In CHERRY & CRANDALL's method the buffer is pH 7.0. The saline solution from Seabra's oscillated from pH6.25-6.9 (table II). Titration - end point. A colorimetric comparison between the sample and the blank as suggested by Seabra becomes very difficult. The end point in the presence of serum, when phenolphtalein is used as indicator, is very difficult to compare with the blank containing water. Conclusion. The differences observed in the results when the same serum was used, must be due to the variations observed with Seabra's reagents.

The determination of blood lipase has been proposed by SEABRA as a method for detecting predisposition to initial or subsequent stages of tuberculosis; normal subjects having high titers (8-12 units), tuberculous patients low ones (5-7), falling to zero in advanced stages of the disease. An assay of the method has been made by the AA. in sera of 238 non tuberculous subjects (419 tests) and 207 tuberculous ones (456 tests) following the technical procedures described by SEABRA. All of them had their Roentgenographies taken at the same day of blood collection. Factors interfering with blood lipase values in tuberculosis are discussed. A relationship between the course of the disease and the serum lipase could not be confirmed. High and low values were found in initial as well as in advanced cases. Our results are in agreement with those recorded in the literature (Figs. I and II). It seems that the general condition, rather than pulmonary lesions are responsible for the blood lipase values. There was no direct relationship between blood lipase titer and severity of pulmonary tuberculosis; however the data presented in this paper do not agree with such correlation, stated by SEABRA, FERNANDES and VICENTE.

Este artículo expone los aspectos básicos de la elaboración un nuevo, y auténtico, Índice de Precios de Consumo de España para el período 1830-1936. Los distintos apartados en que está organizado se dedican a definir el campo de observación y el ámbito analizados, las fuentes empleadas y la metodología utilizada, así como las similitudes y diferencias con otros índices actualmente disponibles. Contiene, asimismo, un contiene un primer y breve análisis de los resultados. La característica más sobresaliente desde la perspectiva de las tendencias de largo plazo del nuevo IPC es una gran estabilidad, quebrada de forma importante, tan sólo, durante los años 1914-1920 bajo la influencia de la Primera Guerra Mundial. La tasa de crecimiento para el conjunto del período no alcanzó siquiera el uno por cien anual, pese al cambio de nivel registrado en aquel breve brote inflacionista.

La febre neutropènica (FN) en el pacient hematològic és una complicació freqüent i potencialment mortal. Els objectius principals d’aquest estudi són descriure les característiques dels pacients i els episodis de FN i estudiar els possibles factors de risc de mortalitat, entre ells l’escala MASC. Es van incloure prospectivament 129 episodis consecutius de FN en 88 pacients hematològics. Tenint en compte l’escala MASC i altres factors es va disenyar una estratègia per determinar els pacients que van ser tractats ambulatòriament. No es va detectar cap event advers en els pacients tractats ambulatòriament (n=26). En l’anàlsi multivariat, l’únic factor de risc per una menor SG als 30 dies va ser la xifra de creatinina (HR 2.3 [95%CI 1.5-3.5], p&0.001).

L’objectiu de l’estudi va ser la determinació de la prevalença de malaltia arterial perifèrica mitjançant el càlcul de l'Índex turmell-braç (ITB) en pacients sense malaltia vascular associada, no diabètics, amb 2 o més factors de risc cardiovascular (RCV); Determinant la seva concordança amb les taules de RCV de REGICOR i SCORE i veure quina d’elles classifica millor a aquests pacients. Es va seleccionar una mostra aleatòria de pacients entre 50 i 65 anys. El resultat de l’estudi demostra que la prevalença és baixa i no s’estableix concordança entre les taules de RCV de REGICOR i SCORE i el càlcul del ITB.

El presente trabajo tiene por objetivo ofrecer una solución para la creación de un índice espacial para la extensión JASPA (Java SPAtial) sobre la base de datos H2. El algoritmo de indexación elegido para la implementación del índice espacial ha sido el Rtree.La implementación se ha realizado con el lenguaje de programación Java lo que ha facilitado su integración con la extensión JASPA y la base de datos H2, dado que ambos proyectos están codificados en el mismo lenguaje. El índice es persistente en memoria secundaria en una tabla de la propia base de datos H2.La solución que se propone está limitada a operaciones espaciales en dos dimensiones y es lo suficientemente flexible como para que no se haya necesitado modificar ni el código fuente de JASPA, ni de H2. Además, se ha previsto que el algoritmo de indexación se pueda mejorar o sustituir fácilmente.Por último, se ha tenido en cuenta que el proceso de creación y manipulación de los índices espaciales sea intuitivo y fácil de usar.

Chronic renal failure is commonly related to hyponutrition, affecting approximately on third of patients with advanced renal failure. We carried out a longitudinal study to assess nutritional evolution of 73 patients on a regular hemodialysis program, assessing changes in the anthropometrical parameter body mass index (BMI) and its correspondence to biochemical nutritional parameters such as total protein (TP) levels and serum albumin (Alb). Every three months plasma TP and albumin levels were collected and BMI was calculated by the standard formula: post-dialysis weight in kg/height in m2. For classifying by BMI categories, overweight and low weight were defined according to the WHO Expert Committee. Studied patients had a mean age of 53 years, 43 were male and 30 were female patients. BMI in women was lower than that in men (p < 0.001), as well as TP (p < 0.001) and Alb (p < 0.001) levels. Mean BMI was 29.3 kg/m2. Three point two percent of the determinations showed low weight, 12.16% overweight, and 83.97% normal BMI. TP were normal in 90.76% and decreased in 9.24%. Alb was normal in 82.2% and low in 17.78%. After the follow-up time (21.6 months, minimum 18 months, maximum 53 months), the Kruskal-Wallis test did not show a statistically significant change for BMI but it did show a change for the biochemical parameters albumin and total proteins (p < 0.05): nutritional impairment in CRF patients is manifested on biochemical parameters (TP and Alb) with no reflection on anthropometrical data.

INTRODUCCIÓN: La asociación entre la arteriopatía periférica y los nuevos eventos cardiovasculares ya es conocida, no así, en función del Índice tobillo-brazo (ITB). OBJETIVOS: Identificar los valores a partir de los que un ITB patológico se correlaciona con la aparición de eventos cardiovasculares. PACIENTES Y MÉTODOS: Se analiza el resgistro FRENA de pacientes a los que se realiza una única medición del ITB. CONCLUSIONES: No hemos encontrado un valor a partir del cual el ITB se asocie significativamente a un peor pronóstico pero sí una asociación entre un ITB & 0.6 y el riesgo de IAM.

INTRODUCTION: Gain weight after transplantation is relatively common, also tends to be multifactorial and can be influenced by glucocorticoids and immunosuppressive medications, delayed graft function and cause serious health complications. OBJECTIVES: Assess changes in weight, degree of obesity and body mass index as well as the effect of immunosuppressive treatment over these 5 years after kidney transplantation. METHODS: The samples were 119 kidney transplant recipients, 70 men and 49 women, that attended the query post for five years. All patients were measured Pretransplant and post (from 1st year to the 5th year) weight, height and body mass index calculated by the formula weight/size2 relating it to immunosuppressive treatment taking. RESULTS: There is a considerable increase of body mass index, weight and degree of obesity in the first year after transplantation to increase more slowly in the next four years. The type of immunosuppressive treatment influence the weight and degree of obesity that occurs in this period of time. CONCLUSIONS: A high prevalence there are overweight and obesity after the transplant especially during the first year. A year patients earn an average of 6.6 kg in weight and an average of 2.5 kg/m2 in their BMI. During treatment should minimize doses of steroids and include dietary treatment and adequate physical exercise

Introduction: The quality of life assessment means investigating how patients perceive their disease. Malnutrition-specific characteristics make patients more vulnerable, so it is important to know how these factors impaction patients’ daily life. Aim: To assess the quality of life in malnourished patients who have had hospital admission, and to determine the relationship of the quality of life with age, body mass index, diagnosis of malnutrition, and dependency. Method: Multicenter transversal descriptive study in 106 malnourished patients after hospital admission. The quality of life (SF-12 questionnaire), BMI, functional independency (Barthel index), morbidity, and a dietary intake evaluation were assessed. The relationship between variables was tested by using the Spearman correlation coefficient Results: The patients of the present study showed a SF-12 mean of 38.32 points. The age was significantly correlated with the SF-12 (r= -0.320, p= 0.001). The BMI was correlated with the SF-12 (r= 0.251, p= 0.011) and its mental component (r= 0.289, p= 0.03). It was also reported a significant correlation between the Barthel index and the SF-12 (r= 0.370, p< 0.001). Conclusions: The general health perception in malnourished patients who have had a hospital admission was lower than the Spanish mean. Moreover, the quality of life in these patients is significantly correlated with age, BMI and functional independency.
