Naamapadam: A Large-Scale Named Entity Annotated Data for Indic Languages
We present, Naamapadam, the largest publicly available Named Entity
Recognition (NER) dataset for the 11 major Indian languages from two language
families. The dataset contains more than 400k sentences annotated with a total
of at least 100k entities from three standard entity categories (Person,
Location, and, Organization) for 9 out of the 11 languages. The training
dataset has been automatically created from the Samanantar parallel corpus by
projecting automatically tagged entities from an English sentence to the
corresponding Indian language translation. We also create manually annotated
testsets for 9 languages. We demonstrate the utility of the obtained dataset on
the Naamapadam-test dataset. We also release IndicNER, a multilingual IndicBERT
model fine-tuned on Naamapadam training set. IndicNER achieves an F1 score of
more than for out of test languages. The dataset and models are
available under open-source licences at

Maximizing success in single-session EUS-directed transgastric ERCP: a retrospective cohort study to identify predictive factors of stent migration
BACKGROUND AND AIMS: EUS-directed transgastric ERCP (the EDGE procedure) is a simplified method of performing ERCP in Roux-en-Y gastric bypass patients. The EDGE procedure involves placement of a lumen-apposing metal stent (LAMS) into the excluded stomach to serve as a conduit for passage of the duodenoscope for pancreatobiliary intervention. Originally a multistep process, urgent indications for ERCP have led to the development of single-session EDGE (SS-EDGE) with LAMS placement and ERCP performed in the same session. The goal of this study was to identify predictive factors of intraprocedural LAMS migration in SS-EDGE.
METHODS: We conducted a multicenter retrospective review that included 9 tertiary medical centers across the United States. Data were collected and analyzed from 128 SS-EDGE procedures. The primary outcome was intraprocedural LAMS migration. Secondary outcomes were other procedural adverse events such as bleeding and perforation.
RESULTS: Eleven LAMS migrations were observed in 128 procedures (8.6%). Univariate analysis of clinically relevant variables was performed, as was a binary logistic regression analysis of stent diameter and stent dilation. This revealed that use of a smaller (15 mm) diameter LAMS was an independent predictor of intraprocedural stent migration (odds ratio, 5.36; 95% confidence interval, 1.29-22.24; P = .021). Adverse events included 3 patients who required surgery and 2 who experienced intraprocedural bleeding.
CONCLUSIONS: Use of a larger-diameter LAMS is a predictive factor for a nonmigrated stent and improved procedural success in SS-EDGE. Although larger patient cohorts are needed to adequately assess these findings, performance of LAMS dilation and fixation may also decrease risk of intraprocedural LAMS migration and improve procedural success
