Quality of life in simultaneous pancreas-kidney transplant recipients

Currently, simultaneous pancreas-kidney transplantation (SPK Tx) is the treatment of choice in selected patients with type 1 diabetes mellitus (DM1) and terminal kidney failure (TRF). A functioning SPK transplant allows dialysis and insulin therapy to be discontinued and stabilizes or improves the complications of DM1. Nevertheless, to a greater or lesser degree, these complications (physical and psychological alterations, secondary effects of immunosuppressive therapy and the need for lifelong medication and medical follow-up) can persist after SPK Tx. Health professionals have mainly investigated the clinical features of transplant recipients. However, in the last few years, interest in analyzing perceived health and health-related quality of life (QoL) has increased. This latter concept includes the features of QoL most closely associated with a particular disease, its treatment and follow-up and therefore those elements most susceptible to modification by the health system. The general aim of this study was to measure health-related QoL in our population with SPK Tx and to determine whether there are significant differences between these patients and those with DM1 and TRF who continue to receive renal replacement therapy (RRT) and insulin therapy. More specific aims were to evaluate whether there are significant differences between the study groups and the means of the Spanish reference population in the distinct dimensions of a QoL questionnaire and whether other variables such as age, sex, years" duration of DM1, length of dialysis, and time since SPK Tx significantly affect health-related QoL.

Acute and Chronic Altitude-Induced Cognitive Dysfunction in Children and Adolescents.

OBJECTIVE: To assess whether exposure to high altitude induces cognitive dysfunction in young healthy European children and adolescents during acute, short-term exposure to an altitude of 3450 m and in an age-matched European population permanently living at this altitude. STUDY DESIGN: We tested executive function (inhibition, shifting, and working memory), memory (verbal, short-term visuospatial, and verbal episodic memory), and speed processing ability in: (1) 48 healthy nonacclimatized European children and adolescents, 24 hours after arrival at high altitude and 3 months after return to low altitude; (2) 21 matched European subjects permanently living at high altitude; and (3) a matched control group tested twice at low altitude. RESULTS: Short-term hypoxia significantly impaired all but 2 (visuospatial memory and processing speed) of the neuropsychological abilities that were tested. These impairments were even more severe in the children permanently living at high altitude. Three months after return to low altitude, the neuropsychological performances significantly improved and were comparable with those observed in the control group tested only at low altitude. CONCLUSIONS: Acute short-term exposure to an altitude at which major tourist destinations are located induces marked executive and memory deficits in healthy children. These deficits are equally marked or more severe in children permanently living at high altitude and are expected to impair their learning abilities.

Susceptibilidad antibiótica de las bacterias causantes de infecciones odontogénicas

Objetivos: Identificar la flora bacteriana y su susceptibilidad a varios antibióticos utilizados en infecciones odontogénicas de localización periapical y en las pericoronaritis del tercer molar inferior, para poder adaptar convenientemente el tratamiento antibiótico a las exigencias de tales infecciones, y evitar así los efectos secundarios y los sobretratamientos con antibióticos. Material y métodos: Se han seleccionado con unos criterios de inclusión y de exclusión a 64 pacientes que presentaban una infección odontogénica. Se recogieron muestras de las lesiones en condiciones de máxima asepsia, evitando la contaminación por flora saprófita bucal. Las muestras se sembraron en medios de cultivo apropiados y se incubaron en condiciones aeróbicas y anaeróbicas; finalmente se procedió a la identificación de los microorganismos aislados y a la determinación de su susceptibilidad antibiótica, los resultados se analizaron estadísticamente mediante la prueba t-Student (para muestras aparejadas y para una muestra). Resultados: Se aislaron un total de 184 cepas bacterianas, incluyendo cocos Gram positivo anaerobios facultativos (68%), bacilos Gram negativo anaerobios estrictos (30%), y bacilos Gram positivo anaerobios facultativos (2%). Independientemente del origen de la infección odontogénica los antibióticos que obtuvieron los mejores resultados en cuanto a mayor sensibilidad y menor resistencia estadísticamente significativos fueron respectivamente la amoxicilina/clavulánico y la amoxicilina (p<0,05). Discusión: Cada vez hay más estudios que indican el alto índice de resistencias a antibióticos en poblaciones bacterianas patógenas que producen infecciones en territorios no bucodentales. A pesar de ello, los niveles de resistencia a los antibióticos en las infecciones odontogénicas no han seguido la misma tendencia, aunque se ha detectado para ciertos antibióticos un alto índice de resistencia. En nuestro trabajo hemos encontrado que los antibióticos de uso común que han obtenido mayor sensibilidad y menor resistencia han sido la amoxicilina en combinación con ácido clavulánico seguido de la amoxicilina.

Worldwide trends in diabetes since 1980: a pooled analysis of 751 population-based studies with 4.4 million participants.

One of the global targets for non-communicable diseases is to halt, by 2025, the rise in the age-standardised adult prevalence of diabetes at its 2010 levels. We aimed to estimate worldwide trends in diabetes, how likely it is for countries to achieve the global target, and how changes in prevalence, together with population growth and ageing, are affecting the number of adults with diabetes. We pooled data from population-based studies that had collected data on diabetes through measurement of its biomarkers. We used a Bayesian hierarchical model to estimate trends in diabetes prevalence-defined as fasting plasma glucose of 7.0 mmol/L or higher, or history of diagnosis with diabetes, or use of insulin or oral hypoglycaemic drugs-in 200 countries and territories in 21 regions, by sex and from 1980 to 2014. We also calculated the posterior probability of meeting the global diabetes target if post-2000 trends continue. We used data from 751 studies including 4,372,000 adults from 146 of the 200 countries we make estimates for. Global age-standardised diabetes prevalence increased from 4.3% (95% credible interval 2.4-7.0) in 1980 to 9.0% (7.2-11.1) in 2014 in men, and from 5.0% (2.9-7.9) to 7.9% (6.4-9.7) in women. The number of adults with diabetes in the world increased from 108 million in 1980 to 422 million in 2014 (28.5% due to the rise in prevalence, 39.7% due to population growth and ageing, and 31.8% due to interaction of these two factors). Age-standardised adult diabetes prevalence in 2014 was lowest in northwestern Europe, and highest in Polynesia and Micronesia, at nearly 25%, followed by Melanesia and the Middle East and north Africa. Between 1980 and 2014 there was little change in age-standardised diabetes prevalence in adult women in continental western Europe, although crude prevalence rose because of ageing of the population. By contrast, age-standardised adult prevalence rose by 15 percentage points in men and women in Polynesia and Micronesia. In 2014, American Samoa had the highest national prevalence of diabetes (>30% in both sexes), with age-standardised adult prevalence also higher than 25% in some other islands in Polynesia and Micronesia. If post-2000 trends continue, the probability of meeting the global target of halting the rise in the prevalence of diabetes by 2025 at the 2010 level worldwide is lower than 1% for men and is 1% for women. Only nine countries for men and 29 countries for women, mostly in western Europe, have a 50% or higher probability of meeting the global target. Since 1980, age-standardised diabetes prevalence in adults has increased, or at best remained unchanged, in every country. Together with population growth and ageing, this rise has led to a near quadrupling of the number of adults with diabetes worldwide. The burden of diabetes, both in terms of prevalence and number of adults affected, has increased faster in low-income and middle-income countries than in high-income countries. Wellcome Trust.

Danza movimiento terapia y abuso sexual

L'organització mundial de la salut, assenyala que la major part de les agressions sexuals tenen com a víctimes a dones i nenes, i són perpetrades per homes i nens. En alguns països, gairebé una de cada quatre dones ha estat víctima de violència sexual per part de la seva parella i fins a una tercera part de les adolescents han sofert una iniciació sexual forçada. Estudis especialitzats fan referència al percentatge de dones que han sofert alguna forma d'abús sexual abans dels 18 anys. En el mateix sentit, enquestes mundials assenyalen que entre el 10% i el 69% de les dones diuen haver estat agredides físicament per una parella masculina en algun moment de la seva vida. La violència sexual infantil provoca a les seves víctimes una sèrie de repercussions i seqüeles, psicològiques, emocionals, socials; compromet el desenvolupament integral de l'individu, i provoca l'aparició d'una sèrie de patologies a l'edat adulta. La present investigació fa una revisió teòrica de la violència sexual, de la violència de gènere, i de les aportacions del procés de recuperació a través de la dansa moviment teràpia d'aquesta població. També es mostra el recorregut del marc d'actuació dels organismes d'ordre públic de la ciutat de Barcelona per a l'atenció i detecció en casos d'abús sexual

El conflicto de Gamonal

En la provincia de Burgos, España, un movimiento vecinal en contra de un proyecto urbanístico acabó derivando en Enero de 2014 en un acontecimiento político con gran seguimiento por parte de los medios de comunicación tradicionales y las redes sociales. La relevancia política de un conflicto en un primer momento local empezó a aumentar y a generar diferentes lecturas e interpretaciones, tanto desde dentro del movimiento como en el resto del Estado español. En este trabajo analizamos las redes de interacciones, los marcos interpretativos del movimiento de protesta y cómo éstos fueron modulándose con base a las distintas fases del conflicto. El análisis sistemático del contenido y las redes sociales de Twitter se ha combinado con siete entrevistas realizadas a participantes en el conflicto. A partir de los datos obtenidos y su análisis, se puede concluir que se dieron cambios importantes en los marcos del movimientohacia perspectivas nacionales y globales en relación con una expansión ydesbordamiento de las redes de interacción que sustentaban el movimiento.

Understanding Flood Regime Changes in Europe: a state-of-the-art assessment

There is growing concern that flooding is becoming more frequent and severe in Europe. A better understanding of flood regime changes and their drivers is therefore needed. The paper reviews the current knowledge on flood regime changes in European rivers that has traditionally been obtained through two alternative research approaches. The first approach is the data-based detection of changes in observed flood events. Current methods are reviewed together with their challenges and opportunities. For example, observation biases, the merging of different data sources and accounting for nonlinear drivers and responses. The second approach consists of modelled scenarios of future floods. Challenges and opportunities associated with flood change scenarios are discussed such as fully accounting for uncertainties in the modelling cascade and feedbacks. To make progress in flood change research, we suggest that a synthesis of these two approaches is needed. This can be achieved by focusing on long duration records and flood-rich and flood-poor periods rather than on short duration flood trends only, by formally attributing causes of observed flood changes, by validating scenarios against observed flood regime dynamics, and by developing low-dimensional models of flood changes and feedbacks. The paper finishes with a call for a joint European flood change research network.

Evaluación de la sintomatología negativista desafiante en niños de 6 a 8 años: concordancia entre padres y maestros

El objetivo principal de este estudio es conocer el grado de concordancia entre los informes proporcionados por padres y maestros acerca de la sintomatología negativista desafiante en niños en edad escolar (6-8 años). Además, se pretende analizar si la edad y el sexo del niño afectan el nivel de acuerdo entre informantes. Padres y maestros evaluaron a 702 niños y niñas de 25 escuelas de la Comarca de Osona, Barcelona (España), mediante el Child Sympton Inventory-4 (versión padres y maestros). Los resultados indican una concordancia muy baja, casi nula, entre las valoraciones de ambos informantes; además, las variables edad y sexo de los niños no representan una diferencia significativa en dichas valoraciones. Los padres tienden a evaluar más síntomas del Trastorno Negativista Desafiante como presentes, y a percibir con mayor intensidad su severidad

Heterogeneidade de álcoois secundários em aguardentes brasileiras de diversas origens e processos de fabricação

Secondary alcohol concentrations in sugar cane spirits from different origins were determined by gas chromatography. A great variation in the concentration of the secondary alcohols was found in these spirits. Of the 33 brands analyzed, 8 of them were found to be out of conformity with the legislation. Sec butanol, for which the maximum allowed concentration level is 100 mg.L-1 in absolute ethanol, was found within a concentration range between 5 mg.L-1, the limit of quantitation (LQ) and 408 mg.L-1 in absolute ethanol. Sugar cane samples from Salinas, MG, were the only ones that exhibited self similarity because of the low concentrations of n-butanol and n-amylic alcohol (< limit of detection LD).

Selective hydrogenation of furfural on Ir/TiO2 catalysts

Titania-supported Ir catalysts were used in the hydrogenation of furfural. Reactions were carried out in a stirred batch type reactor at 0.62MPa and 363K using a 0.10M solution of furfural in a 1:1 mixture n-heptane -ethanol as solvent. Catalysts containing 2 wt% of Ir were reduced in H2 flow at different temperatures in the range 473-773K. The catalysts were characterized by H2 chemisorption, TEM, TPR, TPD of NH3 and XPS. Conversion of furfural is higher at lower reduction temperatures, but leads to byproducts whereas reduction at higher temperatures shows selectivity to furfuryl alcohol close to 100%.

Preparation of association compound between rhodium(II) citrate and β-cyclodextrin

Inclusion compound of rhodium(II) citrate with β-cyclodextrin in a 1:1 molar ratio was prepared using freeze-drying method. X-ray diffactometry, thermal analysis (TG/DTG/DSC), infrared and ¹H-NMR with ¹H spin lattice relaxation (¹H T1) measurements and 13C techniques were used to characterize the system prepared. The results indicated the formation of inclusion or association compounds between rhodium(II) citrate and β-cyclodextrin.

Quantitative control of Lettuce mosaic virus fitness and host defence inhibition by P1-HCPro

Two Lettuce mosaic virus isolates capable of overcoming the resistance afforded by the resistance gene mo1² in lettuce, LMV-AF199 from Brazil, and LMV-E, an European isolate, were evaluated for the rapidity and severity of symptoms induced on the lettuce variety Salinas 88 (mo1²). The mosaic symptoms on Salinas 88 plants inoculated with LMV-AF199 appeared 7 days post-inoculation (dpi) and 15 dpi for LMV-E. The symptoms induced by LMV-AF199 in this cultivar were also more severe than those induced by LMV-E. In order to identify the region of the viral genome responsible for this phenotype, recombinant viruses were constructed between these isolates and the phenotype of each recombinant was analysed. The region encoding proteins P1 and HcPro from LMV-AF199 was associated with the increased virulence in Salinas 88.

Avaliação das propriedades higroscópicas da madeira de Eucalyptus saligna Sm., em diferentes condições de umidade relativa do ar

O estudo da higroscopicidade é indispensável para o entendimento da trabalhabilidade, estabilidade dimensional, resistência mecânica e durabilidade natural da madeira. Neste trabalho objetivou-se a avaliação do teor de equilíbrio higroscópico para diversas condições de umidade relativa do ar, bem como da retratibilidade linear e volumétrica e da densidade básica da madeira de Eucalyptus saligna Sm. A madeira utilizada foi proveniente de árvores com 16 anos de idade, procedentes de talhões experimentais da EMBRAPA Florestas de Colombo, Paraná. Amostras com dimensões de 1,0x2,0x3,0 cm, sendo a última na direção longitudinal, foram colocadas em uma câmara fechada, sob ventilação, próximas de recipientes com soluções salinas supersaturadas, a fim de atingir determinada condição preestabelecida de teor de equilíbrio higroscópico. Após o equilíbrio da umidade da madeira nas distintas condições de umidade relativa, as amostras foram secas em estufa, para posterior avaliação. Os dados relativos à umidade de equilíbrio ajustaram-se muito bem às condições de umidade relativa adotadas neste estudo, tendo sido possível estimar com grande precisão o teor de equilíbrio higroscópico, para a faixa de aproximadamente 20 até 100% de umidade relativa. A madeira em estudo apresentou dados de retratibilidade bastante elevados, se comparados aos de outras da mesma faixa de densidade. Apesar dos elevados coeficientes de contração, o fator anisotrópico ou relação T/R mostrou-se próximo daquele encontrado na grande maioria das madeiras comerciais brasileiras. Verificaram-se ainda coeficientes de contrações mais suaves nos teores de umidade abaixo de 17%.
