Aim Neuroendocrine neoplasms (NENs) are a heterogeneous group of tumours with varying clinical expression and behaviour. Because of indolent behaviour of NENs, reviewing and evaluation of epidemiological characteristics is a challenge. The aim of this study was to assess prevalence of NENs at tertiary hospitals considering age, gender, location, and grade. Methods Electronic files were used for a retrospective assessment of the patients with NENs of the gastroenteropancreatic tract and bronchopulmonary system in tertiary hospitals in Bosnia and Herzegovina over the past 15 years (2005-2020). Results Among 438 patients, 291(66.4%) were males and 147 (33.6%) females; the median age was 62 years. The lungs were the most frequent site, 304 (69.4%), followed by the pancreas, 22 (5.0%), colon, 14 (3.2%), stomach, 13 (2.9%), appendix, 13 (2.9%), rectum,11 (2.5%), small intestine, eight (1.8%) and gallbladder, one (0.2%). Metastases were most frequently found in the liver, 35 (8%) and lymph nodes, 15 (3.42%). Conclusion The results were largely consistent with those in literature, including age, gender, location, and the degree of differentiation. Most metastases originated from high-grade tumours and greater impairment of the liver. The objective of this study was to systematically review the literature regarding the effect of root coverage procedures on tooth survival and periodontal outcomes. A systematic search of the literature was performed according to the PRISMA guidelines. OSI-027 nmr A PICO-based search strategy was performed in six databases. Eligibility criteria included studies comparing tooth survival and periodontal outcomes of teeth treated with root coverage procedures versus teeth that had no treatment. The search resulted in 3,646 articles; 212 articles were downloaded for review, and six articles (three studies) were included. Only a single study reported on tooth survival and found no difference between teeth that underwent root coverage procedures versus those that did not. Although the surgeries described in each study were mostly successful in reducing recession and increasing keratinized gingiva, teeth which did not undergo surgery did not seem to have a clinically significant change in recession. The study with the longety. Furthermore, the amount of recession does not appear to increase a clinically significant amount over time without surgical intervention in the presence of proper maintenance and home care.Uncontrolled movements of laparoscopic instruments can lead to inadvertent injury of adjacent structures. The risk becomes evident when the dissecting instrument is located outside the field of view of the laparoscopic camera. Technical solutions to ensure patient safety are appreciated. The present work evaluated the feasibility of an automated binary classification of laparoscopic image data using Convolutional Neural Networks (CNN) to determine whether the dissecting instrument is located within the laparoscopic image section. A unique record of images was generated from six laparoscopic cholecystectomies in a surgical training environment to configure and train the CNN. By using a temporary version of the neural network, the annotation of the training image files could be automated and accelerated. A combination of oversampling and selective data augmentation was used to enlarge the fully labeled image data set and prevent loss of accuracy due to imbalanced class volumes. Subsequently the same approach was applied to the comprehensive, fully annotated Cholec80 database. The described process led to the generation of extensive and balanced training image data sets. The performance of the CNN-based binary classifiers was evaluated on separate test records from both databases. On our recorded data, an accuracy of 0.88 with regard to the safety-relevant classification was achieved. The subsequent evaluation on the Cholec80 data set yielded an accuracy of 0.84.
