Continuous ADR50 monitoring through automated linkage between endoscopy and pathology: a quality improvement initiative in a Brussels public hospital.

Background And Study Aim: Adenoma detection rate in patients aged 50 years or older (ADR50) is considered by the European Society of Gastrointestinal Endoscopy (ESGE) a key performance measures for lower gastrointestinal endoscopy. Technical and human resources constrain implementation of recording quality monitoring. The aim was to deploy an infrastructure for continuous monitoring of endoscopy quality indicators.

Layer- and cell-type-specific differences in neural activity in mouse barrel cortex during a whisker detection task.

To address the question which neocortical layers and cell types are important for the perception of a sensory stimulus, we performed multielectrode recordings in the barrel cortex of head-fixed mice performing a single-whisker go/no-go detection task with vibrotactile stimuli of differing intensities. We found that behavioral detection probability decreased gradually over the course of each session, which was well explained by a signal detection theory-based model that posits stable psychometric sensitivity and a variable decision criterion updated after each reinforcement, reflecting decreasing motivation. Analysis of multiunit activity demonstrated highest neurometric sensitivity in layer 4, which was achieved within only 30 ms after stimulus onset.

Multi-state study of Enterobacteriaceae harboring extended-spectrum beta-lactamase and carbapenemase genes in U.S. drinking water.

Community-associated acquisition of extended-spectrum beta-lactamase- (ESBL) and carbapenemase-producing Enterobacteriaceae has significantly increased in recent years, necessitating greater inquiry into potential exposure routes, including food and water sources. In high-income countries, drinking water is often neglected as a possible source of community exposure to antibiotic-resistant organisms. We screened coliform-positive tap water samples (n = 483) from public and private water systems in six states of the United States for bla, bla, bla, bla, bla, and bla-type genes by multiplex PCR.

Traditional fermentation of tef injera: Impact on in vitro iron and zinc dialysability.

Tef [Eragrostis tef (Zucc.) Trotter], an ancient cereal mainly produced in Ethiopia, is increasingly getting higher acceptance in the global market because it is gluten free and has high iron content. The aim of this study was to evaluate the in vitro dialysability of Fe and Zn in a backslop fermented gluten free flat bread known as injera.

Effects of chemical pretreatments on the hydrogen isotope composition of 2:1 clay minerals.

Rationale: Clays are a commonly occurring authigenic mineral within soils, and the hydrogen isotope ratios of their structural hydroxyl groups can serve as a useful environmental proxy. Chemical and physical treatments are necessary to eliminate contaminating materials from clays, but they have the potential to alter their isotopic composition.

Methods: Several pure, commonly occurring 2:1 clay mineralogies were treated with typical chemical procedures for the removal of carbonates, organic matter, and amorphous hydroxides.
