RESUMO

INTRODUCTION: Endoscopy plays a fundamental role in inflammatory bowel disease (IBD), and becomes essential in diagnosis, treatment monitoring, and detection and management of complications. MATERIALS AND METHODS: The Pan American Crohn's and Colitis Organization (PANCCO) and the Inter-American Society of Endoscopy (SIED) appointed 22 Latin American experts in IBD to develop a consensus study using the modified Delphi method, based on the best available evidence. A working group of 22 members from 9 countries identified 15 topics and formulated 98 statements, who participated in 2 rounds of voting. It was defined as agreement of ≥80% of experts for each statement. RESULTS: After the voting of all the statements, 8 statements were obtained that did not reach 80% consensus among the participants, so the questions were reconsidered in the Coordinating Committee of the consensus with the participation of the expert reviewers of these questions and 7 final statements were voted again by all the experts in a second round and 1 was eliminated with consensus. After two rounds of voting, the experts reached consensus with literature review with the best available evidence, the most important issues were developed with scientific evidence supporting each of the statements around the topic of endoscopy in IBD. CONCLUSIONS: Consensus statements were developed and based on the best available evidence about endoscopy in inflammatory bowel disease.

RESUMO

Abstract Geographical variation on hip fractures (HF) may be related to the geographical variation of drinking water composition (DWC); minerals in drinking water may contribute to its fragility. We aim to investigate the effects of DWC on HF risk in Portugal (2000-2010). From National Hospital Discharge Register we selected admissions of patients aged ≥50 years, diagnosed with HF caused by low/moderate energy traumas. Water components and characteristics were selected at the municipality level. A spatial generalized additive model with a negative binomial distribution as a link function was used to estimate the association of HF with variations in DWC. There were 96,905HF (77.3% in women). The spatial pattern of HF risk was attenuated after being adjusted for water parameters. Results show an indirect association between calcium, magnesium, and iron and HF risk but no clear relation between aluminum, cadmium, fluoride, manganese, or color and HF risk. Regarding pH, the 6.7pH and 7pH interval seems to pose a lower risk. Different dose-response relationships were identified. The increase of calcium, magnesium, and iron values in DWC seems to reduce regional HF risk. Long-term exposure to water parameters, even within the regulatory limits, might increase the regional HF risk.

Resumo A variabilidade espacial existente na fratura do colo do fêmur (FCF) pode estar relacionada com a variabilidade geográfica da composição da água para consumo (CAC), devido à ação dos minerais na fragilidade óssea. O objetivo do artigo foi investigar o efeito da CAC no risco de FCF em Portugal (2000-2010). Do registo nacional de altas hospitalares, foram selecionadas todas as admissões em indivíduos ≥50, com diagnóstico de FCF causado por trauma de baixo/moderado impacto. Os componentes e características da água foram usados ao nível do município. Um modelo espacial aditivo generalizado, com a distribuição binomial negativa como função de ligação, foi usado para estimar a associação de FCF e as variações da CAC. Foram selecionadas 96.905 FCF (77,3% em mulheres). O padrão espacial de risco de FCF foi atenuado após ser ajustado pelos parâmetros da CAC. Os resultados mostraram uma associação indireta com cálcio, magnésio e ferro. No entanto, com alumínio, cádmio, fluoreto, manganês e cor, a associação com o risco não foi clara. O intervalo de pH de 6,7 a 7 parece apresentar um menor risco. Foram identificadas diferentes dose-resposta. O aumento do cálcio, magnésio e ferro na CAC parece reduzir o risco regional de FCF. Uma exposição a longo prazo, mesmo obedecendo aos limites impostos por lei, parece aumentar o risco regional de FCF.

RESUMO

PURPOSE: To investigate, through a spatio-temporal analysis, the association between the percentages of live births of adolescent mothers (LBAM) and the human development index (HDI), including the three components: income, education and longevity. METHODS: The percentage of LBAM was obtained from the Brazilian Live Births Information System for the state of Minas Gerais, Brazil in the period 2000-2015 and the HDI data and its components were obtained from United Nations Development Program's (UNDP) Human Development Reports. A generalized additive model (GAM) was used to estimate the relative risk of LBAM in relation to the HDI and to identify spatial clusters of the geographical distribution of LBAM, the Moran global and local index was used. RESULTS: There is an association between the HDI and its components with LBAM. The high values of relative risk are spatially concentrated in the northern part of the state of Minas Gerais. The graphs indicated a nonlinear relationship between LBAM over the years. CONCLUSIONS: There is a strong spatial dependence of LBAM in Minas Gerais, which suggests that a geographical location plays a fundamental role in understanding it. The regional disparity confirmed in this study is inherent in the process of human development, it is important for planning actions aimed at the development of these regions in order to minimize existing disparities.

RESUMO

Determinar la utilidad del azul de metileno en el diagnóstico endoscópico de la duodenitis por Giardia. Se realizó un estudio prospectivo, aleatorio, donde se incluyeron 52 pacientes sintomáticos (9 hombres y 43 mujeres), mayores de 18 años del Hospital Dr. Domingo Luciani en el lapso entre julio y octubre de 2001. A toda la población se le realizó una historia clínica, examen seriado de heces y duodenoscopia durante la cual se tomó muestra de aspirado duodenal, citología-cepillado de la mucosa duodenal y biopsia. Se realizó cromoendoscopia con azul de metileno y se observaron los diferentes patrones de la mucosa duodenal. Se estableció el diagnóstico de giardiasis en 8 de los 52 pacientes (15,38 por ciento). Los síntomas de mayor sensibilidad para el diagnóstico de Giardia fueron: epigastralgia (100 por ciento), distensión abdominal (75 por ciento) y flatulencia (75 por ciento), sin embargo el valor predictivo positivo fue bajo: 17,34, 15,78, y 13,33 por ciento respectivamente. Encontramos que para la detección de granulaciones la concordancia interobservador era moderada con un promedio de Kappa de 0,56 y que aumentaba con la tinción a un rango sustancial 0,65. El patrón endoscópico grado 4 tiene la mayor sensibilidad y especificidad (37,5 y 81,81 por ciento) respectivamente con un valor predictivo positivo de 27,27 por ciento y un valor predictivo negativo de 87,87 por ciento. Posterior a la tinción la sensibilidad del patrón de granulaciones se mantuvo en 37,5 por ciento con un descenso en la especificidad a 75 por ciento. La cromoendoscopia con azul de metileno de la mucosa duodenal no mejora significativamente el diagnóstico endoscópico de duodenitis giardiásica
