BACKGROUND/OBJECTIVE: Little is known about the relationship between proton pump inhibitors use and pyogenic liver abscess. The objective of this study was to evaluate the correlation between proton pump inhibitors use and pyogenic liver abscess in Taiwan. METHODS: This was a population-based case-control study using the database of the Taiwan National Health Insurance Program since 2000 to 2011. Subjects aged 20 to 84 who experienced their first episode of pyogenic liver abscess were enrolled as the case group (n = 1372)...

Palbociclib free base capsule is a weak base drug with highly pH-dependent solubility. In vitro and in vivo studies evaluated the impact of acid-reducing agents on exposure of palbociclib and determined whether the impact, if any, can be mitigated by food. A drug-drug interaction study (study 1) was conducted first under fasted conditions and showed that coadministration of multiple doses of the proton-pump inhibitor rabeprazole substantially reduced palbociclib mean area under the concentration-time curve from time 0 to infinity and maximum observed plasma concentration by 62% and 80%, respectively...

Proton pump inhibitors (PPIs) are known as a class of pharmaceutical agents that target H(+)/K(+)-ATPase, which is located in gastric parietal cells. PPIs are widely used in the treatment of gastric acid-related diseases including peptic ulcer disease, erosive esophagitis and gastroesophageal reflux disease, and so on. These drugs present an excellent safety profile and have become one of the most commonly prescribed drugs in primary and specialty care. Except for gastric acid-related diseases, PPIs can also be used in the treatment of Helicobacter pylori infection, viral infections, respiratory system diseases, cancer and so on...

PURPOSE OF REVIEW: Lymphocytic esophagitis (LE) is an unusual esophageal condition defined by an increased number of lymphocytes in the esophageal epithelium. With few published studies of LE available, it is unclear whether LE is a truly distinct clinical entity or a histological manifestation of other known gastrointestinal disorders. This review summarizes recent studies of lymphocytic esophagitis. RECENT FINDINGS: Studies have suggested that LE may be related to eosinophilic esophagitis (EoE) or a manifestation of gastroesophageal reflux disease (GERD)...

Laparoscopic sleeve gastrectomy (LSG) has reached wide popularity during the last 15 years, due to the limited morbidity and mortality rates, and the very good weight loss results and effects on comorbid conditions. However, there are concerns regarding the effects of LSG on gastroesophageal reflux disease (GERD). The interpretation of the current evidence is challenged by the fact that the LSG technique is not standardized, and most studies investigate the presence of GERD by assessing symptoms and the use of acid reducing medications only...

Gastroesophageal reflux disease (GERD) defined as heartburn and/or regurgitation is one of the most common gastrointestinal disorder managed by gastroenterologists and primary care physicians. There is an increase in GERD prevalence since 1995 particularly in North America and East Asia. Over the past three decades proton pump inhibitors (PPIs) had become the mainstay medical therapy for management of GERD. However, over the last decade there is an increasing awareness amongst physicians and patient population regarding the side effects of otherwise considered safe PPIs...

Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the oesophagus. Recognized as a distinct entity only two decades ago, the emergence of the disease along with the availability of new technologies has rapidly opened new research avenues and outlined the main features of the pathogenesis of EoE. Yet, each advance in our understanding of the disease has raised new questions about the previous consensus. Currently, new subsets of the disease challenge our diagnostic criteria. For instance, it was believed that EoE did not respond to proton pump inhibitor (PPI) therapy; however, it has now been shown that a substantial proportion of EoE patients indeed respond to PPIs...

PURPOSE: The impact of proton pump inhibitors (PPIs) on the pharmacokinetics (PK) and efficacy of ceritinib was evaluated. METHODS: A healthy subject drug-drug interaction (DDI) study was conducted to assess the effect of esomeprazole on the PK of a single 750 mg dose of ceritinib. To further investigate the impact of PPIs on the PK and efficacy of ceritinib in ALK-positive cancer patients, two subgroup analyses were performed. Analysis 1 evaluated ceritinib steady-state trough concentration (Ctrough,ss) and overall response rate (ORR) by concomitant use of PPIs in patients from the ASCEND-1, -2, and -3 studies; analysis 2 evaluated ceritinib single-dose and steady-state AUC0-24h and C max by concomitant PPI use in patients from ASCEND-1 using a definition of PPI usage similar to that used in the healthy subject study...

Sodium-ion-pump rhodopsin (NaR) is a microbial rhodopsin that transports Na(+) during its photocycle. Here we explore the photocycle mechanism of NaR from Indibacter alkaliphilus with transient absorption and transient resonance Raman spectroscopy. The transient absorption data indicate that the photocycle of NaR is K (545 nm) → L (490 nm)/M (420 nm) → O1 (590 nm) → O2 (560 nm) → NaR, where the L and M are formed as equilibrium states. The presence of K, L, M, and O intermediates was confirmed by the resonance Raman spectra with 442 and 532 nm excitation...

BACKGROUND: Previous Japanese trials of the docetaxel, cisplatin, and 5-fluorouracil regimen for oesophageal cancer have demonstrated that a large proportion of patients also develop grade IV neutropenia. Our aim was to examine the risk factors for neutropenia in patients treated with this regimen. METHODS: We retrospectively analysed the risk factors for developing grade IV neutropenia in 66 patients with oesophageal cancer using a multivariate analysis. RESULTS: After administering the docetaxel, cisplatin, and 5-fluorouracil regimen, 49 patients (74...

We have created a 4 × 4 droplet bilayer array comprising light-activatable aqueous droplet bio-pixels. Aqueous droplets containing bacteriorhodopsin (bR), a light-driven proton pump, were arranged on a common hydrogel surface in lipid-containing oil. A separate lipid bilayer formed at the interface between each droplet and the hydrogel; each bilayer then incorporated bR. Electrodes in each droplet simultaneously measured the light-driven proton-pumping activities of each bio-pixel. The 4 × 4 array derived by this bottom-up synthetic biology approach can detect grey-scale images and patterns of light moving across the device, which are transduced as electrical current generated in each bio-pixel...

Since the publication of the 2007 dyspepsia guidelines of the Asociación Mexicana de Gastroenterología, there have been significant advances in the knowledge of this disease. A systematic search of the literature in PubMed (01/2007 to 06/2016) was carried out to review and update the 2007 guidelines and to provide new evidence-based recommendations. All high-quality articles in Spanish and English were included. Statements were formulated and voted upon using the Delphi method. The level of evidence and strength of recommendation of each statement were established according to the GRADE system...

BACKGROUND: Present guidelines are conflicting for patients at high risk of both cardiovascular and gastrointestinal events who continue to require non-steroidal anti-inflammatory drugs (NSAIDs). We hypothesised that a cyclooxygenase-2-selective NSAID plus proton-pump inhibitor is superior to a non-selective NSAID plus proton-pump inhibitor for prevention of recurrent ulcer bleeding in concomitant users of aspirin with previous ulcer bleeding. METHODS: For this industry-independent, double-blind, double-dummy, randomised trial done in one academic hospital in Hong Kong, we screened patients with arthritis and cardiothrombotic diseases who were presenting with upper gastrointestinal bleeding, were on NSAIDs, and require concomitant aspirin...

Chromosomally-encoded low membrane permeability and highly efficient efflux systems are major mechanisms by which Pseudomonas aeruginosa evades antibiotic actions. Our previous reports have shown that amphiphilic tobramycin-fluoroquinolone hybrids can enhance efficacy of fluoroquinolone antibiotics against multidrug-resistant (MDR) P. aeruginosa isolates. Herein, we report on a novel class of tobramycin-lysine conjugates containing an optimized amphiphilic tobramycin-C12 tether which sensitize Gram-negative bacteria to legacy antibiotics...

BACKGROUND AND AIMS: Histopathology is the most accurate test to detect H. pylori when performed correctly with unknown validity in daily practice clinic settings. We aimed to determine the rate of potentially false-negative H. pylori results that might be due to continued use of proton pump inhibitors (PPIs) in routine endoscopy practice. We also aimed to establish whether gastroenterologists recommend routine cessation of PPIs before esophagogastroduodenoscopy (EGD) and whether they regularly document that biopsies for H...

Under fluctuating ambient conditions, the ability of plants to maintain hydromineral homeostasis requires the tight control of long distance transport. This includes the control of radial transport within leaves, from veins to mesophyll. The bundle sheath is a structure that tightly wraps around leaf vasculature. It has been suggested to act as a selective barrier in the context of radial transport. This suggestion is based on recent physiological transport assays of bundle sheath cells (BSCs), as well as the anatomy of these cells...

INTRODUCTION: In patients with gastroesophageal reflux disease (GORD), co-existence of functional dyspepsia (FD) is known to be associated with poor response to proton pump inhibitors (PPIs), but the contribution of specific dyspepsia symptoms has not yet been systematically investigated. OBJECTIVE: We aimed to characterize the impact of dyspepsia symptoms on response to PPIs in patients with GORD. METHODS: The enrolled subjects were consecutive patients with a diagnosis of GORD...
