AIM To evaluate differences in capsule endoscopy(CE) performed in the setting of obscure gastrointestinal bleeding(OGIB) among premenopausal women(PMW) and menopausal women(MW).METHODS Retrospective, single-center study, including female patients submitted to CE in the setting of OGIB between May 2011 and December 2016. Patients were divided into 2 groups according to age, considering fertile age as ≤ 55 years and postmenopausal age as > 55 years. The diagnostic yield(DY), the rebleeding rate and the time to rebleed were evaluated and compared between groups. Rebleeding was defined as a drop of Hb > 2 g/dL or need for transfusional support or presence of melena/*** A hundred and eighty three female patients underwent CE for OGIB, of whom 30.6%(n = 56) were PMW and 69.4%(n = 127) were MW. The DY was 30.4% in PMW and 63.8% in MW. The most common findings were angiodysplasias in both groups(PMW: 21.4%, MW: 44.9%)(P = 0.003). In PMW, only 1.8% required therapeutic endoscopy. In 17.3% of MW, CE findingsled to additional endoscopic treatment. Rebleeding at 1, 3 and 5 years in PMW was 3.6%, 10.2%, 10.2% and 22.0%, 32.3% and 34.2% in MW. Postmenopausal status was significantly associated with higher DY(P < 0.001), TY(P = 0.003), rebleeding(P = 0.031) and lower time to rebleed(P = 0.001).CONCLUSION PMW with suspected OGIB are less likely to have significant findings in CE. In MW DY, need for endoscopic treatment and rebleeding were significantly higher while time to rebleed was lower.

AIM To evaluate the impact of the timing of capsule endoscopy(CE) in overt-obscure gastrointestinal bleeding(OGIB). METHODS Retrospective, single-center study, including patients submitted to CE in the setting of overt-OGIB between January 2005 and August 2017. Patients were divided into 3 groups according to the timing of CE(≤ 48 h; 48 h-14 d; ≥ 14 d). The diagnostic and therapeutic yield(DY and TY), the rebleeding rate and the time to rebleed were calculated and compared between groups. The outcomes of patients in whom CE was performed before(≤ 48 h) and after 48 h(> 48 h), and before( 48 h groups(P = 0.03).CONCLUSION Performing CE within 48 h from overt-OGIB is associated to a higher TY and a lower rebleeding rate and longer time to rebleed.

Vadose Zone Heterogeneity Effect on Unsaturated Water Flow Modeling at Meso-Scale

引用

Journal of Water Resource and Protection 2015年第4期7卷 353-368页

作者： Artur Paiva Coutinho Laurent Lassabatere Thierry Winiarski jaime Joaquim da Silva pereira Cabral Antonio Celso Dantas Antonino Rafael Angulo-Jaramillo LEHNA UMR 5023 CNRS ENTPE UCB-Lyon-1 Vaulx-en-Velin France Universidade Federal de Pernambuco Centro de Tecnologia e Geociências Programa de Pós Graduacao em Engenharia Civil/Tecnologia Ambiental e Recursos Hídricos Recife Brasil

The understanding of unsaturated flow in heterogeneous formations is a prerequisite to the understanding of pollutant transfer in the vadose zone and the proper management of infiltration basins settled over such heterogeneous formations. This study addresses the effect of lithological heterogeneity of a glaciofluvial deposit on flow in the vadose zone underneath an infiltration basin settled in the Lyon suburbs. The basin had already been the subject of several previous studies, some of which demonstrated the impact of soil heterogeneity. But all of them were only based on the sedimentological study of a trench and no study addressed the potential spatial variability of results due to the spatial variability of soil heterogeneity. In this study, we model flow in the vadose zone for several case studies, including drainage, water infiltration during a rainfall event, and a complete meteorological chronic. These calculations were conducted for several sections, previously characterized in the basin using GPR and sedimentological study and compared with a blank (homogeneous section). The results clearly show that heterogeneity impacts unsaturated flow and that these impacts depend upon the section considered. Some geometrical architectural and textural parameters were proposed to explain the spatial variability and effect of the soil heterogeneity on unsaturated flow, thus establishing the first step towards modeling unsaturated flow in the basin at the meso-scale.
