PROBLEM: Abstract: BACKGROUND Confocal laser endomicroscopy (CLE) is rapidly emerging as a valuable tool for gastrointestinal endoscopic imaging. Fluorescent contrast agents are used to optimize imaging with CLE, and intravenous fluorescein is the most widely used contrast agent. Fluorescein is FDA-cleared for diagnostic angiography of the retina. For these indications, the safety profile of fluorescein has been well-documented; however, to date, fluorescein is not cleared for use with CLE. AIMS To estimate the rate of serious and total adverse events attributable to intravenous fluorescein when used for gastrointestinal CLE.
METHODS We performed a cross sectional survey of 16 International Academic Medical Centres with active research protocols in CLE that involved intravenous fluorescein. Centres using i.v. fluorescein for CLE who were actively monitored for adverse events were included.
RESULTS Sixteen centres performed 2272 gastrointestinal CLE procedures. The most common dose of contrast agent was 2.5-5 mL of 10% sodium fluorescein. No serious adverse events were reported. Mild adverse events occurred in 1.4% of individuals, including nausea/vomiting, transient hypotension without shock, injection site erythema, diffuse rash and mild epigastric pain. The limitation is that only immediate post procedure events were actively monitored.
CONCLUSIONS Use of intravenous fluorescein for gastrointestinal CLE appears to be safe with few acute complications.. Title: The safety of intravenous fluorescein for confocal laser endomicroscopy in the gastrointestinal tract.

PROBLEM: Abstract: Cellular circular RNAs (circRNAs) are generated by head-to-tail splicing and are present in all multicellular organisms studied so far. Recently, circRNAs have emerged as a large class of RNA which can function as post-transcriptional regulators. It has also been shown that many circRNAs are tissue- and stage-specifically expressed. Moreover, the unusual stability and expression specificity make circRNAs important candidates for clinical biomarker research. Here, we present a circRNA expression resource of 20 human tissues highly relevant to disease-related research: vascular smooth muscle cells (VSMCs), human umbilical vein cells (HUVECs), artery endothelial cells (HUAECs), atrium, vena cava, neutrophils, platelets, cerebral cortex, placenta, and samples from mesenchymal stem cell differentiation. In eight different samples from a single donor, we found highly tissue-specific circRNA expression. Circular-to-linear RNA ratios revealed that many circRNAs were expressed higher than their linear host transcripts. Among the 71 validated circRNAs, we noticed potential biomarkers. In adenosine deaminase-deficient, severe combined immunodeficiency (ADA-SCID) patients and in Wiskott-Aldrich-Syndrome (WAS) patients' samples, we found evidence for differential circRNA expression of genes that are involved in the molecular pathogenesis of both phenotypes. Our findings underscore the need to assess circRNAs in mechanisms of human disease. KEY MESSAGES: circRNA resource catalog of 20 clinically relevant tissues. circRNA expression is highly tissue-specific. circRNA transcripts are often more abundant than their linear host RNAs. circRNAs can be differentially expressed in disease-associated genes..

PROBLEM: Abstract: The mucin profiles of the gastric mucosa in Lundehunds suffering from intestinal lymphangiectasia were examined and compared to the mucin profiles in control dogs from other breeds. A previous study performed on this material had shown that all examined Lundehunds had gastritis and about 30% had gastric carcinoma. Neutral and acid mucins were identified using the periodic acid-Schiff (PAS) and Alcian blue (pH 2.5) periodic acid-Schiff (AB-PAS) methods. The acid mucins were divided into sialomucins and sulfomucins based on their reaction with high-iron diamine Alcian blue, pH 2.5 (HID-AB). In Lundehunds with chronic atrophic gastritis in the fundic and body regions the surface and foveolar epithelium showed a predominantly normal mucin profile although some Lundehunds had a reduced mucin content. The mucous neck cells extended from below the gastric foveolae towards the muscularis mucosae. Morphometric examination showed that the abnormal presence of mucous neck cells occupied 41% of the height of the gastric mucosa in Lundehunds compared to only 19% in the control dogs (p<0.05). Of the four Lundehunds with gastric carcinoma, two possessed neoplastic cells that contained minimal or no mucins. The amount and type of mucin in the neoplastic cells of the remaining two Lundehunds varied both between individuals and within a neoplasm. This study shows that the abnormal presence of mucous neck cells and the associated pseudopyloric metaplasia comprised the predominant changes in the gastric mucin profiles of Lundehunds..
