24 April 2017 Cryoablation in the management of Barrett's esophagus. "The concept of cryotherapy is appealing.

20 April 2017 Endoscopic gastric mucosal atrophy distinguishes the characteristics of superficial esophagogastric junction adenocarcinoma. "Two distinct types of EGJ cancer were identified, with and without endoscopic gastric mucosal atrophy. These types were associated with different tumor locations." (Digestive Endoscopy)

These BE subjects may be candidates for endoscopic therapy. LGD was a marker of prevalent HGD/EAC in 18% of patients." (American Journal of Gastroenterology)

3 April 2017 Gastroesophageal reflux disease-related symptom recurrence in patients discontinuing proton pump inhibitors for Bravo esophageal wireless pH monitoring study. "Symptom exacerbation following PPI cessation for at least 7 days correlated with acid reflux severity assessed by Bravo testing. Patients off PPIs for 7 days had a higher likelihood of experiencing worsening symptoms, compared with those off PPIs for more than 7 days. These findings suggest that when PPIs are held for 7 days or less prior to Bravo testing, acute worsening of upper GI symptoms due to the abrupt discontinuation of therapy may influence the Bravo results. The etiology of this may be related to rebound acid hypersecretion and needs to be further elucidated in future studies." (Revista de Gastroenterologia de Mexico)

Very few data were available to make a conclusion regarding long-term benefits and harms of PPI reduction or discontinuation." (Cochrane)

15 March 2017 Determinants of reflux-induced chronic cough. "The presence of a larger volume of refluxate and oesophageal exposure to reflux for a longer period of time seems to play an important role in inducing cough, while the acidity of the refluxate seems to be less relevant. This helps explain the observation that most patients with chronic cough tend not to benefit from acid inhibitory treatment." (Gut)

February 2017 Risk of oesophageal adenocarcinoma in individuals with Barrett's oesophagus. "This population-based study indicates that OAC is primarily diagnosed during the first months following an initial diagnosis of BO. This could justify a changed surveillance strategy of BO with a repeated thorough endoscopy shortly after initial BO diagnosis to identify prevalent early OAC or HGD." (European Journal of Cancer)

19 February 2017 The risk of oesophageal adenocarcinoma in a prospectively recruited Barrett's oesophagus cohort.  "Patients with BO had a modest increase in all-cause mortality and a large increase in OAC mortality, particularly if fit for surveillance. Low-grade dysplasia and the length of the BO segment were associated with developing OAC." (United european Gastroenterology Journal)

19 February 2017 Acid reflux and coughing: What's the connection? "A cough associated with other symptoms of acid reflux or LPR should also be seen by a doctor." (Medical News Today)

17 February 2017 Epidemiology and natural history of gastro-esophageal reflux disease. "[Data from medical literature] seem to suggest that both NERD and mild esophagitis tend to remain as such over time and the progression from NERD to ERD, from mild to severe ERD and from ERD to Barrett's esophagus may occur only in a small number of cases, ranging from 0% to 30%, 10%-22% and 1%-13%, respectively."

14 February 2017 Body weight trajectories and risk of oesophageal and gastric cardia adenocarcinomas  "Being overweight in early adulthood and weight gain later in life were each associated with increased risks of EA and GCA. This underscores the potential of weight control programs for reducing EA and GCA risk." (BJC)

14 February 2017 Recurrence of Barrett's Esophagus is Rare Following Endoscopic Eradication Therapy Coupled With Effective Reflux Control. "The current study highlights the importance of reflux control in patients with BE undergoing EET. In this setting, EET has long-term durability with low recurrence rates providing early evidence for extending endoscopic surveillance intervals after EET." (American Journal of Gastroenterology)

March 2017 Candidate serum metabolite biomarkers for differentiating gastroesophageal reflux disease, Barrett's esophagus, and high-grade dysplasia/esophageal adenocarcinoma.  "Serum metabolite differences can be detected between individuals with GERD versus BE, and between those with BE versus HGD/EA, and may help differentiate patients at different stages of progression to EA." (Metabolomics)

13 February 2017 A Double-blind, Randomized, Multicenter Clinical Trial Investigating the Efficacy and Safety of Esomeprazole Single Therapy Versus Mosapride and Esomeprazole Combined Therapy in Patients with EsophagealReflux Disease. "The combination proton pump inhibitor with mosapride showed a tendency for upper abdominal pain, belching, and total GERD symptoms scores to improve more rapidly. This suggests that combination therapy with esomeprazole and mosapride will be useful for rapid improvement of specific GERD symptoms such as upper abdominal pain and belching in ERD patients." (Journal of Neurogastroenterology & Motility)

(Journal of Digestive Diseases)

10 February 2017 Risk of malignant progression in Barrett's esophagus indefinite for dysplasia. "Risk of progression to advanced neoplasia after the first year following IND diagnosis is lower than previously thought and similar to other recent studies. Longer BE segment and smoking history may help predict which IND patients are more likely to progress to HGD/EAC and therefore identify patients who may warrant closer monitoring." (Diseases of the Esophagus)

7 February 2017 Bile salt receptor TGR5 is highly expressed in esophageal adenocarcinoma and precancerous lesions with significantly worse overall survival and gender differences. "Our findings indicated that TGR5 may play an important role in the development and prognosis of EAC through a bile acid ligand. Gender differences in TGR5 and VDR expression may explain why males have a higher incidence of EAC compared to females." (Clinical & Experimental Gastroenterology)

February 2017 Discordance Among Pathologists in the United States and Europe in Diagnosis of Low-Grade Dysplasia for Patients With Barrett's Esophagus "In an analysis of criteria used in histopathologic diagnosis of LGD, we did not observe improvement in level of agreement among experienced pathologists, even after accounting for inflammation. The level of inter-observer agreement increased with level of pathologist confidence. There was also a difference in reading of histopathology samples of BE tissues between US and European pathologists." (Gastroenterology)

February 2017 Outcomes of Pregnancies for Women Undergoing Endoscopy While They Were Pregnant: A Nationwide Cohort Study "Adverse pregnancy outcomes are rare in women undergoing endoscopy during pregnancy. Potential excess risks, if any, seem minimal and should be weighed against the need for timely investigation and treatment of women where an underlying GI disease may be a more severe threat to pregnancy outcome than the endoscopy." (Gastroenterology)

1 February 2017 Adam, Eve and the reflux enigma: age and sex differences across the gastro-oesophageal reflux spectrum. "Two views may explain our findings. First, women have either milder reflux, or reduced mucosal sensitivity hence reflux remains silent for longer. Alternatively, women genuinely develop reflux later, that is, are more protected and for longer from developing GORD and its complications. Early evidence is emerging that female sex hormones may indeed have a protective role in GORD during the reproductive period."  (European Journal of Gastroenterology & Hepatology)
