Feasibility and Efficacy of Magnetic Sphincter Augmentation for the Management of Gastroesophageal Reflux Disease Post-Sleeve Gastrectomy for Obesity.

Background: Patients with medically intractable GERD after laparoscopic sleeve gastrectomy (LSG) have limited surgical options. Fundoplication is difficult post-LSG. Roux-en-Y gastric bypass may be used as a conversion procedure but is more invasive with potential for serious complications.

Advances in the observation and understanding of changes in sea level and tides.

Climate change, of which sea level change is one component, is seldom out of the news. This paper reviews developments in the measurement and understanding of changes in sea level and tides, focusing on the changes during the past century. The main aim has been to demonstrate how sea level and tidal science are now connected intimately with the fields of climate change and geodesy.

Multicenter randomized controlled trial comparing forceps biopsy sampling with wide-area transepithelial sampling brush for detecting intestinal metaplasia and dysplasia during routine upper endoscopy.

Background And Aims: Intestinal metaplasia (IM) in the esophagus is a potentially premalignant mucosal change. The aim of this study was to compare the frequency of IM detection during upper endoscopy by forceps biopsy sampling (FB) versus wide-area transepithelial sampling (WATS) brush.

Methods: Patients presenting for upper endoscopy for foregut symptoms or surveillance of Barrett's esophagus (BE) at 9 centers in the United States were randomized to either FB or WATS.

Assessment of Tidal Range Changes in the North Sea From 1958 to 2014.

We document an exceptional large-spatial scale case of changes in tidal range in the North Sea, featuring pronounced trends between -2.3 mm/yr at tide gauges in the United Kingdom and up to 7 mm/yr in the German Bight between 1958 and 2014. These changes are spatially heterogeneous and driven by a superposition of local and large-scale processes within the basin.

Non-linear interaction modulates global extreme sea levels, coastal flood exposure, and impacts.

We introduce a novel approach to statistically assess the non-linear interaction of tide and non-tidal residual in order to quantify its contribution to extreme sea levels and hence its role in modulating coastal protection levels, globally. We demonstrate that extreme sea levels are up to 30% (or 70 cm) higher if non-linear interactions are not accounted for (e.g.

Comment on "A semi-empirical approach to projecting future sea-level rise".

Rahmstorf (Reports, 19 January 2007, p. 368) presented an approach for predicting sea-level rise based on a proposed linear relationship between global mean surface temperature and the rate of global mean sea-level change. We find no such linear relationship.

Some important issues to do with long-term sea level change.

This paper gives an overview of several important issues concerned with the measurement and understanding of long-term sea level change, which is one of the most important topics in sea level science. The issues discussed span science, technology and our ability to fund and operate the national and global observation networks required for a proper understanding of long-term change and its impacts. Many of these topics were explored at a 'Celebration of UK sea level science' at the Royal Society on 16-17 February 2004, and are discussed further in a number of papers in this volume.
