Abstract Background The best maintenance therapy after a steroid-responsive acute severe ulcerative colitis (ASUC) episode remains poorly studied and is not addressed in current guidelines. We aimed to compare the impact of different treatment strategies following hospitalization for ASUC. Methods Multicentric, multinational, retrospective cohort study including patients hospitalized with ASUC, between 2010-2021, who responded intravenous steroids (Oxford Criteria). Patients were categorized...
Milk and cheese products serve an important economic social function in Brazil, as most of the production is carried out on small-scale family farms. Farmers who fail to meet institutional market requirements related scale milk quality often abandon activity or turn selling raw unlicensed cheese. In this research, we adopted theory planned behavior (TPB) a theoretical framework investigate farmers' intention regularize production. Interviews were conducted site with 286 producers Paraná...
Abstract Background The use of oral iron in deficiency (ID) and ID anemia IBD is controversial. Its lower costs ease application have to be weighed against the fear side effects questions about its efficacy. aim this study was assess efficacy tolerability Sucrosomial® correcting IBD. As a secondary objective we aimed impact ID, disability Methods This prospective bicentric study. patients diagnosed with or between november 2022 2023 treated were included. Half physicians instructed prescribe...
Abstract Background Corticosteroids (CS) are effective in induction of remission inflammatory bowel disease (IBD), but should be used sparingly, given their unfavourable safety profile. In fact, CS excess has been incorporated quality care standards IBD, highlighting the importance auditing use. A sparing strategy is frequently recommended due to risk side effects, its consequences IBD outcomes have less studied. Our primary aim was evaluate current use and patients, compare them with a...
Background: Universal adhesive systems used for restorative clinical procedures are like orthodontics and may be a viable option.This study evaluated the effectiveness of universal in enhancing durability shear bond strength (SBS) remnant index (ARI) orthodontic brackets to enamel.Material Methods: 100 bovine incisors were divided into five groups (n=20), according applied systems: Primer Transbond XT; Ambar; Ambar Universal; Single Bond Adper 2. Bracket from each tooth submitted SBS test...
Nanoparticles with size in the range from 10 nm to 300 and three different materials (Au nm, Ag 20 PSL 30 100 nm) were used this supplementary comparison. The selected nanoparticles meet requirements of measurement methods such as Atomic Force Microscopy (AFM), Transmission Electron (TEM), Scanning (SEM), Dynamic Light Scattering (DLS), Differential Mobility Analyzer (DMA), Small Angle X-Ray for forth. All 37 participating laboratories returned results, but not all able perform 5...
pH is a widely used control parameter for several industrial processes. Thus, its correct determination and uncertainty estimation are extremely important. The Guide to the Expression of Uncertainty in Measurement (ISO-GUM) has been extensively estimation. This work uses Monte Carlo simulation estimate primary system measurements regional comparison (SIM 8.11P-1) which INMETRO participated. results compared with ISO-GUM analytical approach good agreement was found.
Currently, the use of algorithms and computer vision systems for metrological purposes has increased in different areas knowledge to reduce human error process deviations, consequently increasing reliability reducing measurement uncertainties. This study presents a model estimating uncertainty Feret's diameter (DF ) measurements scanning electron microscopy (SEM) images from regular irregular gunshot residue (GSR) particles at magnifications. The data were extracted using automatic algorithm...
Main text A pilot study for the thickness measurement of HfO 2 films was performed by Surface Analysis Working Group (SAWG) Consultative Committee Amount Substance (CCQM). The aim this to ensure equivalency in capability national metrology institutes films. In study, thicknesses six with nominal from 1 nm 4 were measured X-ray Photoelectron Spectroscopy (XPS), Reflectometry(XRR), Fluorescence (XRF), Transmission Electron (TEM), Spectroscopic Ellipsometry (SE) and Rutherford Backscattering...
CCQM key comparison K-129 for the quantitative analysis of Cu(In,Ga)Se 2 (CIGS) films has been performed by Surface Analysis Working Group (SAWG) Consultative Committee Amount Substance (CCQM). The objective this is to compare equivalency National Metrology Institutes (NMIs) and Designated (DIs) measurement mole fractions Cu, In, Ga Se in a thin CIGS film. measurand average test alloy film unit fraction (mol/mol). Mole with metrological % mol/mol can be practically converted atomic at %. In...
Main text The CCQM-K172 key comparison on measurement of Specific Adsorption A [mol/kg] Ar zeolite at liquid argon temperature (to enable a traceable determination the Surface Area by following ISO 9277) has been performed Analysis Working Group (SAWG) Consultative Committee for Amount Substance (CCQM). objective this is to compare equivalency National Metrology Institutes (NMIs) and Designated (DIs) specific adsorption Ar, BET surface area) microporous substances (zeolites, sorbents,...
