A novel upflow microaerobic sludge reactor (UMSR) was constructed to treat manure-free piggery wastewater with high NH4(+)-N and low COD/TN ratio. In the light of the potential effect of effluent reflux ratio (RR) on nitrogen removal, performance of the UMSR was evaluated at 35°C and hydraulic retention time 8h with RR decreased from 45 to 25 by stages. A COD, NH4(+)-N and TN removal of above 77.1%, 80.0% and 86.6%, respectively, was kept with a RR over 35. To get an effluent of TN not more than 80mg/L with a TN load removal above 0...

OBJECTIVES: Feeding difficulties are frequent in children with neurological impairments and can be associated with undernutrition, growth failure, micronutrients deficiencies, osteopenia, and nutritional comorbidities. Gastrointestinal problems including gastroesophageal reflux disease, constipation, and dysphagia are also frequent in this population and affect quality of life and nutritional status. There is currently a lack of a systematic approach to the care of these patients. With this report, European Society of Gastroenterology, Hepatology and Nutrition aims to develop uniform guidelines for the management of the gastroenterological and nutritional problems in children with neurological impairment...

INTRODUCTION: Laparoscopic fundoplication is the gold standard treatment for gastroesophageal reflux disease (GERD) refractory to medical management. Although many studies have compared Nissen fundoplication (NF) to Toupet fundoplication (TF), it is unclear which operation provides the best long-term reflux control. The objective of this study was to evaluate long-term quality-of-life (QoL) outcomes after NF versus TF. METHODS: Clinical data from our single academic institutional foregut database were used to identify patients who underwent NF or TF (June 2010 to May 2016)...

BACKGROUND & AIMS: Little is known about the causes of heartburn in patients with gastro-esophageal reflux disease (GERD). Visible epithelial damage is seldom associated with symptom severity, evidenced by the significant symptom burden in patients with non-erosive reflux disease (NERD) compared to patients with erosive reflux disease (ERD) or Barrett's esophagus (BE). We studied the distribution of mucosal nerve fibers in patients with NERD, ERD, and BE, and compared the results with those of healthy subjects...

Patients affected by gastroesophageal reflux disease (GERD) have a poor quality of life caused by several manifestations such as cough, asthma, laryngitis and dental erosion. The clinical conditions are highly disabling for patients and symptoms are difficult to manage. These conditions lead to many discomforts which contribute to an increase of the disease perception. For these reasons, it is important to improve the interventions on psychological aspects that ameliorate the patients' quality of life. The application of IARA model has proven useful to decrease GERD symptoms, distress and medication intake and to increase adherence to care, improving the patient's quality of life...

Hamish Philpott, Rami Sweis
PURPOSE OF REVIEW: This review aims to discuss the putative relationship between hiatus hernia and dysphagia. RECENT FINDINGS: Proposed mechanisms of dysphagia in patients with hiatus hernia are usually difficult to identify, but recent advances in technology (high-resolution manometry with or without concomitant impedance, ambulatory pH with impedance, videofluoroscopy, and the endoluminal functional lumen imaging probe (EndoFLIP)) and methodology (inclusion of swallows of various consistencies and volumes or shifting position during the manometry protocol) can help induce symptoms and identify the underlying disorder...

Purpose To elaborate on a planar anatomic variant of great saphenous vein as a potential therapeutic pitfall in the treatment of venous reflux. Materials and methods Lower extremity veins in 568 limbs with great saphenous vein insufficiency were sonographically mapped. A rather overlooked variation, the saphenous bow, was studied with emphasis on anatomic clarification and its involvement in venous insufficiency. Results This variation, observed in 5.1% (n = 29) of limbs, comprised two segments; one uninterrupted great saphenous vein proper coursing throughout saphenous compartment and one extra-compartmental segment originating distally from and proximally fusing with it...

REVIEW
Young Kwang Shim, Nayoung Kim
The first histamine H2 receptor antagonists (H2RAs) were developed in the early 1970s. They played a dominant role in treating peptic ulcer disease and gastroesophageal reflux disease (GERD). H2RAs block the production of acid by H(+), K(+)-ATPase at the parietal cells and produce gastric luminal anacidity for varying periods. H2RAs are highly selective, and they do not affect H1 receptors. Moreover, they are not anticholinergic agents. Sequential development of H2RAs, proton pump inhibitors (PPIs), and discovery of Helicobacter pylori infection changed the paradigm of peptic ulcer disease with marked decrease of morbidity and mortality...

Nardostachyos Radix et Rhizoma (NR), the root and rhizome from either Nardostachys jatamansi Batal or Nardostachys jatamansi DC, is known to have biological functions including neuro-protective and anti-pancreatitis activity. The main bioactive compounds within NR are all classified as sesquiterpenes, and include desoxo-narchinol A, nardosinonediol, and nardosinone. Although NR is a valuable herb that is widely used in many Asian countries, robust quality control protocols for NR are still in question, especially those that can analyze the three main active compounds...
