Prediction of adenoma recurrence after piecemeal endoscopic mucosal resection: interobserver agreement and utilization of the Sydney EMR recurrence tool.

Prediction of adenoma recurrence after piecemeal endoscopic mucosal resection: interobserver agreement and utilization of the Sydney EMR recurrence tool. Scand J Gastroenterol. 2020 Apr 23;:1-5 Authors: Silva JC, Pinho R, Fernades C, Proença L, Rodrigues A, Silva AP, Ponte A, Rodrigues J, Sousa M, Gomes AC, Afecto E, Carvalho J Abstract Background and aims: Piecemeal endoscopic mucosal resection (pEMR) allows resection of larger non-invasive colorectal lesions. Adenoma recurrence is an important limitation and occurs in ≤20%. The present study aimed to validate the Sydney EMR recurrence tool (SERT) score as a predictor of both endoscopic and histologic recurrence and evaluate interobserver agreement in adenoma recurrence based on endoscopic scar assessment, among nonexperts in EMR.Methods: Retrospective cohort and cross-sectional study, in which all patients submitted to pEMR in a tertiary care center in Portugal, between 2012 and 2018 were included. SERT-score was calculated for all lesions and compared with the SMSA (size, morphology, site, access) score already validated as a predictor of adenoma recurrence. Image based offline analysis was performed to evaluate adenoma recurrence prediction and assess the interobserver agreement within a heterogeneous group of participants, mostly composed by nonexperts in EMR.Results: There was a moderate positive correlation between the SERT and SMSA scores (p

Discussion Biometrics uses “biological characteristics or behavioral features to recognize an individual.” Using biometric data requires acquisition of data of sufficient quantity and quality for recognition and comparison, and the biometric data needs to remain stable over time (i.e. – the person should be able to be recognized in the future using the data. Data acquisition and storage cost and size are also important variables. Privacy and security are also paramount considerations. Biometrics use in pediatric patients has several applications including: Newborn tracking -using biometrics for iden...

CONCLUSIONS: 131I-therapy can induce salivary gland toxicity with high inter- but also high intrapatient variation among separate gland locations, which can be assessed with PSMA PET/CT. This new technique offers potential to guide further development and evaluation of protective measures in patients receiving 131I-therapy. PMID: 32619138 [PubMed - as supplied by publisher]

Credit: Holy Family Hospital.By Nachiket MorBANGALORE, India, Jul 5 2020 (IPS) Universal healthcare (UHC) is an important global goal because of its close links to poverty reduction and enhancement of the growth potential of countries. While several countries can now be said to be well on their way towards achieving this goal, several others, most notably large ones such as India and Nigeria, are decidedly not. Though there are a number of reasons for this, perhaps the most important one has been the position taken by the international development commun...

We describe two rapid assessment techniques that allow for elucidation of the cell wall polymers of root hairs and high-resolution analysis of surface features of various vegetative organs. Live organism immunolabeling of cell wall polymers employing light microscopy and confocal laser scanning microscopy can be effectively performed using a large microplate-based screening strategy (see Figs. 1 and 2). Rapid cryofixation and imaging of variable pressure scanning electron microscopy also allows for imaging of surface features of all portions of the plant as clearly seen in Fig. 3.

Abstract The importance of lignocellulosic materials in various research areas including for example biorefinery processes and new biomaterials is constantly rising. Therefore, a detailed knowledge on the macromolecular assembly of plant cell walls is needed. However, despite the tremendous progress in the structural and chemical analysis of plant cell walls there are still uncertainties concerning the ultrastructure. This is either due to Rayleigh criterion based limitations of the analytical methods or the relatively low chemical information gained with high spatial resolution techniques. In this chapter scannin...

Abstract Field emission scanning electron microscopy (FESEM) is a powerful tool for analyzing surface structures of biological and nonbiological samples. However, when it is used to study fine structures of nanometer-sized microfibrils of epidermal cell walls, one often encounters tremendous challenges to acquire clear and undistorted images because of two major issues: (1) Preparation of samples suitable for high resolution imaging; due to the delicateness of some plant materials, such as onion epidermal cell walls, many things can happen during sample processing, which subsequently result in damaged samples or i...

Authors: Andriotis EG, Monou PK, Louka A, Papaefstathiou E, Eleftheriadis GK, Fatouros DG Abstract In the current study a 3D-printable system was developed, based on natural, food-grade and non-toxic materials that may be used as a platform technology to host cannabinoids, and more specifically CBD for medicinal purposes. Pectin and honey were combined towards the fabrication of 3D printable inks that form solid structures upon drying. This model food-grade 3D-printed system was evaluated as a host matrix for the incorporation of CBD, in the form of inclusion complexes with β-cyclodextrins. The prepared solid ...

Authors: de Oliveira FAB, Mazo DF Abstract Background: Direct access endoscopy (DAE) is the procedure performed without the pre-evaluation of the patient by a specialist. It is widely available in many medical services around the world, but there is lack of data about this strategy in the setting of the public health system in Brazil. Therefore, the aim of this study is to compare the main endoscopic findings of upper gastrointestinal endoscopy requested through DAE and by specialists.Methods: Longitudinal, retrospective single center study in patients who underwent upper digestive endoscopy in a public healthcare ...

Radical changes occurred in the Italian NHS and thus in GI departments, as only urgent endoscopies were guaranteed. The study aimed to report how the demand for urgent endoscopy changed during the COVID-19 pandemic in Italy and to evaluate the appropriateness of urgent referrals in the Endoscopy Unit.Material and methods: Nation-wide, cross-sectional survey study in 54 Italian GI Units. Data were collected regarding urgent endoscopies (EGD, CS, ERCP) in two dif...
