Abstract: With 10 million new cases and three million deaths a year,the tuberculosis (TB) is one of the illnesses infectocontagiosasmore important of the world, preceded only by the malaria andthe VIH-SIDA, for what it is supported as one of the illnessestransmissible of big worry and occupation for the systemsof health. But not always it was like that, a moment came in the historyof this illness that one believed inclusive in his eradication, withoutit impeded the appearance of new,and the conjunction of old factorsthey have helped to reposicionar to the TB as a problem of attentionimmediate for the public global health. In this work we developa brief review of four factors that are impactandodeeply in the present and future of the TB: 1) The poverty; 2)The resistance to drugs, 3) The systems of diagnosis, and 4) youraffiliation with the virus of the inmunodefi human science. So much froma global perspective as national, and we conclude with the brief one evaluation on as we are preparing ourselves to face tothe tuberculosis

Abstract: Introducción: Los fitoestrógenos son compuestos naturales que forman parte de numerosos alimentos de origen vegetal y que podrían modular tanto aspectos relacionados con hormonas, como reacciones de tipo antioxidante, por lo que conocer las ingestas de estos compuestos en diferentes poblaciones aclararía aspectos importantes sobre sus respuestas en el organismo. Objetivo: Valorar la exposición de fitoestrógenos por medio de la dieta, en una muestra de mujeres de todas las edades pertenecientes a la comunidad universitaria (docentes, administrativas y estudiantes), residentes en la provincia de Granada, Espa a. Material y método: 52 mujeres adultas, con edades entre 20 y 63 a os completaron individualmente un cuestionario de frecuencia de consumo de alimentos (FFQ) compuesto por un total de 144 alimentos. Se ponderó el consumo diario de fitoestrógenos totales estandarizando los valores refiriendo estos a la daidzeína como sustancia patrón (mg/día). El análisis estadístico se realizó con SPSS 15.0 (SPSS Inc., Chicago, IL, USA), con un nivel de significancia de p < 0,05. Resultados: Muestran que la ingesta total de fitoestrógenos referidos a la daizdeína fue de 0,89 mg/día, y la mayor parte de fitoestrogenos fue consumido en forma de lignanos. El consumo total de isoflavonas, fue de 0,12 mg/día, el de lignanos fue de 1,32 mg/día y la ingesta de coumestrol no fue significativa. Un Análisis de Regresión Lineal, determinó la ecuación para calcular la ingesta de fitoestrógenos, tomando en cuenta 9 grupos de alimentos (R: 0,918; p < 0,001). Discusión: La ingesta media de fitoestrógenos en Espa a, es comparable con las ingestas descritas por estudios similares en Alemania, Inglaterra y Estados Unidos (< 1 mg/d). Conclusiones: No existen diferencias significativas en la ingesta de fitoestrógenos, cuando se compara la muestra por edad, nivel educativo, actividad física o estado civil. La ingesta de fitoestrógenos (mg/día) puede ser estimada a partir de la ingesta (g/día) de 9 grupos de alimentos. Introduction: The phytoestrogens are naturally occurring compounds that are part of many foods of plant origin and could therefore modulate aspects related hormones, such as type of antioxidant reactions, learning about intakes of these compounds in different populations clarify important aspects on their responses on the human body. Objective: To evaluate the exposure of phytoestrogens through diet, in a sample of women of all ages belonging to the university community (teachers, students and administrative), residents in the province of Granada,Spain.

The analysis of variance shows significant differences (P < 0.05) among accessions for titratable acidity, pH, lycopene on wet and dry basis, in the CIE chromaticity coordinates L* , a * b*, and in the maturity index. GTO-11, OAX-115, PH-102 and PH-96 accessions stood out for their lycopene content on wet and dry basis with values above 20 and 300 mg 100 g-1, respectively. Lycopene content in samples of ground tomato fruits decreased after storing them at -20oC; it also decreased in the scalded samples immersed in boiling water. México es un centro de domesticación y diversificación del tomate con diversas poblaciones nativas cultivadas y variantes silvestres, pero poco documentadas en términos de sus características físicas, químicas y nutricionales. Con el objetivo de evaluar el contenido de licopeno, ácido ascórbico y otras características fisicoquímicas de los frutos de una muestra de tomate originaria de diferentes regiones de México, y evaluar el efecto de almacenamiento sobre la pérdida de licopeno, se hizo una colecta y posteriormente la siembra y trasplante en invernadero de trece accesiones bajo un dise o de bloques completos al azar con cuatro repeticiones. El análisis de varianza detecta diferencias significativas (P < 0.05) entre accesiones para acidez titulable, pH, licopeno en base húmeda y seca, en las coordenadas cromáticas CIE L* , a * y b*, y en el índice de madurez. Las accesiones GTO-11, OAX-115, PH-102 y PH-96 sobresalen en contenido de licopeno en base húmeda y seca con valores mayores a 20 y 300 mg 100 g-1, respectivamente. El contenido de licopeno en muestras molidas de frutos de tomate y almacenadas a -20oC, decreció a medida que se incrementó el tiempo de almacenamiento, aún en las muestras escaldadas, inmersión en agua en ebullición.

Abstract: To evaluate the effects of dietary protein levels and probiotic supplementation on microbial intestinal fermentation, diarrhea incidence, and performance in weaned piglets, 162 piglets were randomly assigned to three treatments: high-protein diet (20%), with antibiotics (HPa); high-protein diet (20%), without antibiotics (HP); and low-protein diet, without antibiotics but with probiotics (LPpb). Piglets and feed were weighed weekly to calculate the average daily gain (ADG), average daily feed intake (ADFI), and gain: feed ratio (G:F). Four piglets per treatment were killed on day 21 postweaning to collect ileal and colon digesta for measurement of short-chain fatty acids (SCFAs), branched-chain fatty acids (BCFAs), lactic acid (LA), and ammonia (AM). In the digesta collected from the ileum and colon, piglets fed the HPa diet had the lowest concentration of volatile fatty acids. Additionally, the HP diet produced the highest concentration of BCFAs, while the LPpb diet produced moreacetic, propionic, and butyric acids than the HPa and HP diets. Piglets fed the HP diet had higher incidence and severity of diarrhea than piglets fed LPpb and HPa diets, and similar values were observed between these two groups. The second week postweaning was the most critical for diarrhea measurements; during the second week, animals had higher incidence and severity of diarrhea. Piglets fed the HPa and LPpb diets had similar ADGs, while those fed the HP diet had the poorest ADG. Similar results were observed with ADFI and G:F. A low-protein diet supplemented with probiotics changed the fermentation profile, reducing toxic metabolites, promoting gut health, decreasing the incidence and severity of postweaning diarrhea, and improving the performance of piglets.

Abstract: Se realizó una investigación descriptiva, cualicuantitativa, de corte transversal y prospectiva con el objetivo de evaluar el efecto de la percepción del riesgo en el cuidado enfermero en paciente viviendo con VIH-sida. El universo fue de 3067 enfermeros (as) siendo la muestra de 613 enfermeros (as) lo que representa un 20 % del universo, teniendo como criterio de inclusión que el personal seleccionado estuviera vinculado directamente a labores asistenciales y representadas las diferentes categorías ocupacionales. Se obtuvo como resultados que el porciento reflejado a la no percepción fue de 18,4 % y predominó la categoría técnica para un 41,5 %. En relación al cumplimiento de seguridad ante los incidentes y el uso de dispositivos dispuestos, el 5.5% no lo tienen en cuenta y al relacionar como lo asumen con las categorías profesionales, los enfermeros básicos representaron el 7,3 % y le siguieron los licenciados para un 6,2 %. El 25,3 % de la muestra han sufrido accidentes o incidentes que propician a la exposición del riesgo. Se refleja en el análisis de la percepción de ser contaminado el 24,6 %, no lo siente a pesar de que incide en el paciente o individuo supuestamente sano. We performed a descriptive, quali-quantitative, cross-sectional and prospective in order to evaluate the effect of risk perception in nursing care in patient living with HIV-AIDS. The universe was 3067 nurses (as) being the sample of 613 nurses (as) representing 20% of the universe, with the inclusion criteria were selected personnel work directly linked to welfare and represented different occupational categories. Such analysis indicated that the percent reflected a failure to collect was 18.4%, predominantly technical category to 41.5%. Regarding compliance to security incidents and the use of devices located, 5.5% is not taken into account and assumed to relate as professional categories, basic nurses accounted for 7.3% and was followed for graduates 6.2%. The 25.3% of the sample have had accidents or incidents that lead to risk exposure. It is reflected in the analysis of the perception of being contaminated by 24.6%, although it does not feel that affects the individual patient or supposedly healthy.
