We aimed to assess the short-term outcomes of per-oral endoscopic myotomy (POEM) compared with laparoscopic Heller myotomy (LHM) for achalasia through a meta-analysis of nonrandomized comparative studies.We searched PubMed, Embase, Medline, Cochrane Library, and Google Scholar for studies that compared POEM and LHM for achalasia and were published between January 1, 2008 and December 31, 2014. ...

Sundown of the twentieth century saw the emergence of the World Wide Web. A decade later, semantic web (SW) envisioned enriching of web-accessible information and services with machine-processable semantics to solve the problems of information management and sharing which are aroused by the success of the web. However, success of the SW largely depends on the availability of formal ontologies f...

Despite renewed interest in roles played by Christianity in the poetry of Elizabeth Barrett Browning (EBB), few scholars have discussed her treatment of the body of Christ—understood as both the figure of Christ and his body of followers—in her antislavery poem, “The Runaway Slave at Pilgrim’s Point”. This article argues that “The Runaway Slave” reworks portrayals of the body of Christ in trans...

BACKGROUND High-resolution manometry (HRM) has improved the accuracy of manometry in detecting achalasia and has helped distinguish between clinically relevant subtypes. This study investigated whether HRM metrics correlate with the achalasia symptoms and symptomatic outcomes of peroral esophageal myotomy (POEM). METHODS Of the 30 patients who were enrolled, 25 were treated with POEM, 12 of w...

Unsupervised dependency parsing is one of the most challenging tasks in natural languages processing. The task involves finding the best possible dependency trees from raw sentences without getting any aid from annotated data. In this paper, we illustrate that by applying a supervised incremental parsing model to unsupervised parsing; parsing with a linear time complexity will be faster than th...

BACKGROUND AND STUDY AIMS Although peroral endoscopic myotomy (POEM) is being performed more frequently, the learning curve for gastroenterologists performing the procedure has not been well studied. The aims of this study were to define the learning curve for POEM and determine which preoperative and intraoperative factors predict the time that will be taken to complete the procedure and its d...

is an idiopathic motility disorder that results from degeneration of the myenteric plexus in the wall of the esophagus and the lower esophageal sphincter (LES). 1 In esopha-geal manometry, achalasia is characterized by impaired relaxation of LES and loss of peristalsis in the body of the esophagus. Achalasia results in severe dysphagia for solids and liquids. Additional symptoms can also develo...

BACKGROUND Although there are screening tools to aid clinicians in assessing the risk of opioid misuse, an instrument to assess opioid-related knowledge is not currently available. The purpose of this study was to develop a content-valid, understandable, readable, and reliable Patient Opioid Education Measure (POEM). METHODS Using concept mapping, clinicians caring for patients with chronic p...
