- Item805 Complications of Gastrointestinal Endoscopy in 85,391 Procedures(Mosby-Elsevier, 2012) Espino Espino, Alberto Antonio; García Astorquiza, Ximena Andrea; Mac Namara, Macarena; Richter Roca, Hugo Michael; Pimentel Muller, Fernando; Biel Morales, Francisco Javier; Robles García, Camila Fernanda; Callejas, Matías F.; Sharp Pittet, Allan Carlos; Donoso, Andrés; Candia Balboa, Roberto Andrés; González Donoso, Robinson; Jarufe Cassis, Nicolás; Arrese, Marco; Álvarez Lobos, Manuel; Padilla Pérez, OslandoBackground: Complications are inherent to GI endoscopy (GIE) and do not necessarily imply endoscopist's negligence. They may occur even using highest standards of practice. Objectives: To analyze the frequency and severity of complications occurring within 30 days after of the GIE at a single university hospital in Chile. Methods: We reviewed the records about patients who underwent GIE from January 2001 through May 2011. Results: A total of 85,391 GIE were evaluated. Procedures: 46,928 (55%) esophagogastroduodenoscopy (EGD); 27,993 (32.8%) diagnostic colonoscopies; 1427 (1.7%) polypectomies; and other procedures (hemostasis, variceal band ligation (VBL), foreign-body removal, dilation, stents, PEG, ERCP, EUS and double balloon endoscopy) 9043 (10.5%). A total of 299 complications were associated with GIE (59 % female, mean age 63 years, range 5 - 99). The overall complications rate was 0.35% (cardiopulmonary (CP) 0.1%, bleeding 0.07%, perforation 0.06%, infection 0.04%, pancreatitis 0.03% and other). The overall complication rate was higher in therapeutic procedures (TP) vs diagnostic procedures (DP) (2.7% v/s 0.16%, p<0.0001). The percentage of severe complications was higher in TP vs DP (52.3% vs 28.4%, p<0.0001). The overall complication rate for EGD was 0.14% (CP 0.07%, perforation 0.017%, bleeding 0.019%); diagnostic colonoscopy, 0.27% (CP 0.1%, perforation 0.06%, bleeding 0.02%); and polypectomy, 1.8% (CP 0.14%, perforation 0.28%, bleeding 0.98%). A total of 15 deaths occurred (overall rate 0.018%, 83% in TP). The overall mortality rate was higher in TP vs DP (0.2% v/s 0.003%, p<0.0001). The mortality rate for PEG was 0.7%; VBL 0.4%; ERCP 0.2%; diagnostic colonoscopy 0.004%; EGD 0.004%; and polypectomy 0%. Conclusions: GIE is associated with complications and mortality. The severity and risk of complications are higher in therapeutic procedures. These risks should be clearly explained to patients and their family before the procedure.

- ItemAdaptation process of multimodal books for deaf people(2017) Veliz, Soledad; Espinoza, Victoria; Sauvalle, Ignacia; Arroyo, Rodrigo; Garolera, Marion; Aviles, FP; Sanchez, R; Bykbaev, VR; Guerra, PIIn this study, we present the systematized results of the experience of adapting three multimodal digital books for deaf and hard of hearing (D/HH) children and young people. A five-phase methodology is proposed and challenges, problems and possible solutions are put forward. It is expected that the systematization results useful for other educative resources teams developing fot D/HH children and young people.

- ItemAn Empirical Analysis of Rumor Detection on Microblogs with Recurrent Neural Networks(SPRINGER INTERNATIONAL PUBLISHING AG, 2019) Bugueno, Margarita; Sepulveda Villalobos Gabriel Andres; Mendoza Rocha Marcelo Gabriel; Meiselwitz, GThe popularity of microblogging websites makes them important for information dissemination. The diffusion of large volumes of fake or unverified information could emerge and spread producing damage. Due to the ever-increasing volume of data and the nature of complex diffusion, automatic rumor detection is a very challenging task. Supervised classification and other approaches have been widely used to identify rumors in social media posts. However, despite achieving competitive results, only a few studies have delved into the nature of the problem itself in order to identify key empirical factors that allow defining both the baseline models and their performance. In this work, we learn discriminative features from tweets content and propagation trees by following their sequential propagation structure. To do this we study the performance of a number of architectures based on recursive neural networks conditioning for rumor detection. In addition, to ingest tweets into each network, we study the effect of two different word embeddings schemes: Glove and Google news skip-grams. Results on the Twitter16 dataset show that model performance depends on many empirical factors and that some specific experimental configurations consistently drive to better results.

- ItemAn extension of SPARQL for RDFS(SPRINGER-VERLAG BERLIN, 2008) Arenas, Marcelo; Gutierrez, Claudio; Perez, Jorge; Christophides, V; Collard, M; Gutierrez, CRDF Schema (RDFS) extends RDF with a schema vocabulary with a predefined semantics. Evaluating queries which involve this vocabulary is challenging, and there is not yet consensus in the Semantic Web community on how to define a query language for RDFS. In this paper, we introduce a language for querying RDFS data. This language is obtained by extending SPARQL with nested regular expressions that allow to navigate through an RDF graph with RDFS vocabulary. This language is expressive enough to answer SPARQL queries involving RDFS vocabulary, by directly traversing the input graph.
