    We surveyed the nematode assemblages associated with populations of the parthenogenetic whiptail lizard Ameivula nativo from six coastal restinga areas in eastern Brazil: Setiba, Comboios and Guriri (State of Espirito Santo) and Guaratiba, Prado and Maraú (State of Bahia). A total of five nematode species (Physaloptera retusa, Physalopteroides venancioi, Skrjabinelazia intermedia, Subulura lacertilia and Parapharyngodon sp.) were recorded from the six different populations of A. nativo. There was considerable variation in overall prevalence of infection (1-42%) among study sites, but geographical distance among areas did not influence similarity in the composition of nematode assemblages. Overall intensity of infection was not affected by lizard body size and did not seem to affect host body condition, based on pooled data of all populations. The studied populations of the unisexual A. nativo had relatively low prevalences and intensities of infection compared to some bisexual congeners and to sympatric lizards from other families for which such data are available. We believe that the low richness of the nematode fauna associated with A. nativo, both locally and regionally, may reflect its narrow geographic distribution and the low diversity of habitats it occupies.

    A new combinational fungicide formulation trifloxystrobin 25%+tebuconazole 50% (Nativo 75WG), introduced as a part of resistance management strategy, was studied for dissipation behaviour on apple fruits. Nativo 75WG was sprayed twice at the rate of 400 g and 800 g a.i. ha(-1) equal to trifloxystrobin application rate of 100 and 200 g a.i. ha(-1) and tebuconazole at application rate of 200 and 400 g a.i. ha(-1) at four different locations in the Northwest Himalayan region of India. The fruit samples collected at 10d interval and soil samples taken at harvest time were analyzed after second spray. The residual concentrations of trifloxystrobin, its acid metabolite CGA 321113 and tebuconazole were measured. Residues of both fungicides were determined by using gas chromatograph, Agilent 6890N having electron capture detector. The mean initial deposits of trifloxystrobin at four locations were found to be in the range of 0.333-0.387 mg kg(-1) and 0.512-0.714 mg kg(-1) at the application rate of 100 and 200 g a.i. ha(-1), and half-life were found between 19.38-24.93 d and 19.84-28.86 d at the respective doses. The Σ-trifloxystrobin and tebuconazole residues were below determination limit in 40 d apple fruits and soil samples. Initial deposits of trifloxystrobin and tebuconazole were below their Codex MRLs at the respective single doses. The half life value of the tebuconazole deposits ranged between 19.38-25.99 d and 19.84-28.86 d at the respective single and double dose. The study thus suggests 1d pre harvest interval for safe consumption of apple fruit after the application of Nativo 75 WG at single dose. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Objetivos: Este estudio fue diseñado para comparar el riesgo de trastornos de conducta alimentaria (TCA) entre adolescentes nativos e inmigrantes residentes en Madrid, así como para determinar la posible influencia del tiempo de residencia en el riesgo de los inmigrantes. Métodos: Se llevó a cabo un estudio transversal durante el periodo comprendido entre noviembre 2007 y febrero 2008 sobre una muestra representativa de adolescentes residentes en Madrid, con edades de entre 13 y 17 años (n = 2.077, 1.052 mujeres). Los datos se recogieron usando la versión española del cuestionario SCOFF para la detección de trastornos alimentarios. Otros factores considerados fueron el país de nacimiento, el tiempo de residencia y diversas variables biológicas, socio-demográficas, relativas a estilo de vida y la salud. Resultados: Según los tres modelos de regresión logística construidos, las mujeres adolescentes inmigrantes en conjunto mostraron un mayor riesgo de TCA (OR = 1,95; 95%CI 1,29-2,95; p = 0,001) que las nativas. Además, la probabilidad de sufrir TCA fue mayor entre las adolescentes inmigrantes con una residencia en España < 6 años que en las nativas (OR = 2,44; 95%CI 1,42-4,18; p = 0,001), mientras que no se encontraron diferencias entre las adolescentes nativas y las inmigrantes con un tiempo de residencia ≥6 años. No se observaron diferencias en el riesgo de TCA entre los adolescentes varones nativos y los inmigrantes, tanto en conjunto como según tiempo de residencia. Conclusiones: La condición de inmigrante y el tiempo de residencia son factores relevantes a la hora de considerar el riesgo de TCA en adolescentes residentes en Madrid.

    Resumen Introducción: Los aneurismas asociados a malformaciones arteriovenosas (MAV) son lesiones vasculares que suelen encontrarse hasta en el 15% de los casos, incrementando el riesgo global de hemorragia. La conducta frente a los aneurismas asociados es dicotómica en la literatura, mientras existen reportes de la desaparición de los mismos luego de la exéresis de la MAV, otros artículos enfatizan su tratamiento precoz. El síndrome del acento extranjero es un raro trastorno neurológico en el que el paciente habla su lengua materna como lo haría una persona extranjera y suena con “acento” extranjero a oídos de los oyentes nativos. Objetivo: Presentar un paciente que desarrolla el síndrome del acento extranjero posterior a la exéresis de una MAV y la evolución de un aneurisma asociado. Presentación de caso: Paciente pediátrico que luego de la exéresis de una MAV fronto-opercular posterior izquierda remite por completo un aneurisma de hiperflujo asociado, presentando en el postquirúrgico el síndrome del acento extranjero. Conclusión: Queda reportado el caso de este raro síndrome y la resolución espontánea de un aneurisma proximal luego de la exéresis de una MAV. PMID:28480115

    The persistence and dissipation kinetics of trifloxystrobin and tebuconazole on onion were studied after application of their combination formulation at a standard and double dose of 75 + 150 and 150 + 300 g a.i. ha(-1). The fungicides were extracted with acetone, cleaned-up using activated charcoal (trifloxystrobin) and neutral alumina (tebuconazole). Analysis was carried out by gas chromatograph (GC) and confirmed by gas chromatograph mass spectrometry (GC-MS). The recovery was above 80% and limit of quantification (LOQ) 0.05 mg kg(-1) for both fungicides. Initial residue deposits of trifloxystrobin were 0.68 and 1.01 mg kg(-1) and tebuconazole 0.673 and 1.95 mg kg(-1) from standard and double dose treatments, respectively. Dissipation of the fungicides followed first-order kinetics and the half life of degradation was 6-6.6 days. Matured onion bulb (and field soil) harvested after 30 days was free from fungicide residues. These findings suggest recommended safe pre-harvest interval (PHI) of 14 and 25 days for spring onion consumption after treatment of Nativo 75 WG at the standard and double doses, respectively. Matured onion bulbs at harvest were free from fungicide residues.

    Dissipation of trifloxystrobin and tebuconazole were studied following two applications of a combination formulation of Nativo 75 WG (trifloxystrobin 25% + tebuconazole 50%) @ 250 and 500 g ha(-1) at 10 days interval. Samples of chili were collected at 0, 1, 3, 5, 7, 10 and 15 days after the last application. Red chili and soil samples were collected after 20 days of last application. Half-life period for trifloxystrobin were found to be 1.81 and 1.58 days and for tebuconazole these values were observed to be 1.37 and 1.41 days, respectively, at single and double the application rates. Trifloxystrobin residues dissipated below its limit of quantification (LOQ) of 0.01 mg kg(-1) after 5 and 7 days, respectively, at single and double the application dosages whereas tebuconazole residues took 7 and 10 days, respectively. Red chili & soil samples collected after 20 days did not reveal the presence of trifloxystrobin and tebuconazole at their determination limit of 0.01 mg kg(-1).

    Introdução: Perdas de peso melhoram o controlo da tensão arterial em indivíduos hipertensos. As intervenções comportamentais para a perda de peso parecem ser menos eficazes nos imigrantes de origem africana (IOA). Os principais objetivos foram avaliar os efeitos no peso de uma intervenção alimentar em hipertensos nativos de origem portugueses (NOP) e IOA; identificar fatores de sucesso na perda de peso; avaliar a evolução dos conhecimentos e adesão às recomendações alimentares. Material e Métodos: Foram selecionados aleatoriamente hipertensos medicados seguidos nos cuidados de saúde primários para um estudo de duas fases, observacional (15 meses) e de intervenção comportamental (seis meses). Os participantes foram divididos em dois grupos: IOA e NOP. Foram dadas recomendações alimentares e de estilos de vida em sessões individuais presenciais e telefónicas. Resultados: Dos 110 participantes, com IMC médio de 31,6 ± 3,7 kg/m2 e idade média 61,3 ± 10,0 anos, 60 eram imigrantes. Durante a intervenção os NOP perderam 1,4 ± 2,7% do peso e os IOA 0,8 ± 3,6%, sendo a perda superior comparativamente com a fase observacional. Ser do sexo masculino e consumir pelo menos duas porções de lacticínios magros por dia associou-se a maior perda de peso durante a intervenção, independentemente da idade e origem. Houve um aumento significativo no número de recomendações dietéticas conhecidas e cumpridas, com os NOP a cumprirem em média mais recomendações. Discussão: A intervenção foi bem sucedida relativamente à perda de peso, especialmente no grupo dos NOP, confirmando outros estudos. Conclusão: A intervenção aumentou os conhecimentos e adesão às recomendações, realçando a pertinência da educação alimentar, culturalmente adaptada, nos cuidados de saúde primários.

    Introducción: el colágeno hidrolizado (CH) es una mezcla de péptidos de colágeno con un peso molecular (PM) inferior a 5.000 Da. Se obtiene de la gelatinización y posterior hidrólisis enzimática de colágeno nativo procedente de tejidos animales ricos en esta proteína. Existe abundante evidencia científica sobre el efecto positivo que la toma de CH ejerce sobre las patologías osteoarticulares degenerativas y el envejecimiento dérmico. Objetivo: revisar los estudios científicos existentes actualmente sobre el CH y evaluar su acción terapéutica sobre algunos tejidos colaginosos como cartílagos, huesos y piel. Resultados: hasta la fecha se han realizado más de 60 estudios científicos (in vitro, in vivo, clínicos y de biodisponibilidad) sobre la efectividad del CH a la hora de reducir las consecuencias del deterioro y pérdida de colágeno tisular como son el dolor y el desgaste articular (artrosis), la pérdida de masa ósea (osteoporosis) y el envejecimiento dérmico. Conclusiones: los estudios preclínicos indican que el CH estimula la regeneración de los tejidos colaginosos, potenciando la síntesis de colágeno tisular y también de los restantes componentes minoritarios de dichos tejidos (proteoglicanos y ácido hialurónico). Los estudios clínicos demuestran que la ingesta continuada de CH ayuda a reducir el dolor articular de desgaste, a ralentizar la pérdida de masa ósea y a atenuar los signos de envejecimiento dérmico. Estos resultados, junto con su alto nivel de seguridad y tolerancia, hacen del CH un suplemento adecuado para tomar a largo plazo, indicado para prevenir y tratar enfermedades crónicas degenerativas (artrosis y osteoporosis), así como para prevenir y atenuar el envejecimiento dérmico.

    Land managers and policymakers need information about soil change caused by anthropogenic and non-anthropogenic factors to predict the effects of management on soil function, compare alternatives, and make decisions. This is particularly relevant in highly fragile ecosystems such as wetlands or humid systems. The wetlands require the presence of three key components: hydric soils, hydrophytic vegetation and wetland hydrology. Therefore, the presence of hydric soils in humid systems is essential for the existence of a wetland. In Chile, one of the geographic zones with the greatest diversity of humid systems is the coast of the Araucanía Region, which contains one of the largest and most threatened humid systems of the region, Puren Marshes, whose soils are only generically described as alluvial terraces and miscellaneous swamp. In this area, studies have reported a high intensity of anthropogenic activity, generating soil erosion, loss of wetland coverage and landscape alteration. For this first stage of a main investigation about the vulnerability of hydric soils to changes in patterns of soil use, the objective was to characterize the variables of soil use in the Puren Marshes and determinate the direction and magnitude of change in soil use in the study area for the period between 1994 and 2007 (the official reports indicate that until 1994, the total area of Puren Marshes was 1147 ha). For the analyses, were used official reports of soil use, the coverages were obtained from the project map databases "Catastro y Evaluación de los Recursos Vegetacionales Nativos de Chile" 1993 and its update for La Araucanía, Regional Government of La Araucanía 2011, DMF CONAF 2010 and IGM 2007. The map information was processed in ARCGIS 9.3.1 software under UTM coordinates, datum WGS 84 and 18 South Time extended. Was developed a multitemporal analysis by construction of transition matrix and confusion matrix. The results obtained show that for the period analysed, the

    To translate and perform the cultural adaptation of the tool Functional Assessment of Chronic Illness Therapy - Cervical Dysplasia (FACIT-CD) to the Portuguese language. A descriptive cross-sectional study, with translation and cultural adaptation of the assessment tool performed according to international guidelines and the Functional Assessment of Chronic Illness Therapy (FACIT) protocol group. It involved eight experts, six from Brazil, one from Portugal and one from the United States. After translation and back-translation of the tool, the semantic analysis process was carried out. We randomly included 20 women aged between 18 and 70 years with altered cervical cytology exam, seen at the Department of Prevention and Gynecologic Oncology - Hospital de Câncer de Barretos. The sample consisted of women with low education level. In the first pre-test, ten women participated and half of them considered the questions CD1, CD2 and CD3 as difficult, because they did not understand the meaning of the term "pelvic area". The question CD5, "I worry about spreading the infection", was also considered difficult to understand by five women. After the reconsideration of the expert committee and FACIT group, the second pre-test was performed. At this stage, we concluded that the previously raised understanding problems had been solved. The translated version of FACIT-CD in universal Portuguese language is equivalent to the original version in English and was easily understood by patients with cervical intraepithelial neoplasia.
