PURPOSE
Reflux esophagitis is a condition characterized by inflammation and irritation of the esophagus, resulting from the backflow of stomach acid and other gastric contents into the esophagus. Columbianadin is a coumarin derivative that exhibits anti-inflammatory and antioxidant effects. In this study, we tried to scrutinize the protective effect of Columbianadin against acute reflux esophagitis in rats.
METHODS
RAW 264.7 cells were utilized to assess cell viability and measure the production of inflammatory parameters. The rats received anesthesia, and reflux esophagitis was induced via ligation of pylorus and fore stomach and corpus junction. Rats received the oral administration of Columbianadin (25, 50 and 100 mg/kg) and omeprazole (20 mg/kg). The gastric secretion volume, acidity, and pH were measured. Additionally, the levels of oxidative stress parameters, cytokines, and inflammatory markers were determined. At the end of the study, mRNA expression was assessed.
RESULTS
Columbianadin remarkably suppressed the cell viability and production of tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), and prostaglandin (PGE2). Columbianadin treatment remarkably suppressed the secretion of gastric volume, total acidity and enhanced the pH level in the stomach. Columbianadin remarkably altered the level of hydrogen peroxidase, free iron, calcium, and plasma scavenging activity, sulfhydryl group; oxidative stress parameters like malonaldehyde, glutathione, superoxide dismutase, catalase, glutathione peroxidase; inflammatory cytokines viz., TNF-α, IL-6, IL-1β, IL-10, IL-17, and monocyte chemoattractant protein-1; inflammatory parameters including PGE2, iNOS, COX-2, and nuclear kappa B factor (NF-κB). Columbianadin remarkably (P < 0.001) suppressed the mRNA expression TNF-α, IL-6, IL-1β and plasminogen activator inhibitor-1.
CONCLUSIONS
Columbianadin demonstrated a protective effect against acute reflux esophagitis via NF-κB pathway.

INTRODUCTION AND OBJECTIVES
Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide and can progress to non-alcoholic steatohepatitis (NASH) and, ultimately, cirrhosis. Clostridioides difficile is the most common nosocomial cause of diarrhea and is associated with worse clinical outcomes in other liver diseases, including cirrhosis, but has not been extensively evaluated in concomitant NAFLD/NASH.
MATERIALS AND METHODS
We conducted a retrospective cohort study using the National Inpatient Sample database from 2015 to 2017. Patients with a diagnosis of CDI, NAFLD, and NASH were identified using International Classification of Diseases (Tenth Revision) codes. The outcomes of our study include length of stay, hospitalization cost, mortality, and predictors of mortality.
RESULTS
The CDI and NASH cohort had a higher degree of comorbidity burden and prevalence of peptic ulcer disease, congestive heart failure, diabetes mellitus, and cirrhosis. Patients with NASH and CDI had a significantly higher mortality rate compared to the CDI only cohort (mortality, 7.11 % vs. 6.36 %; P = 0.042). Patients with CDI and NASH were at increased risk for liver-related complications, acute kidney injury, and septic shock (P < 0.001) compared to patients with CDI only. Older age, intestinal complications, pneumonia, sepsis and septic shock, and liver failure conferred an increased risk of mortality among the CDI and NASH cohort.
CONCLUSIONS
Patients with NASH had a higher rate of liver-related complications, progression to septic shock, and mortality rate following CDI infection compared to the CDI only cohort.

INTRODUCTION
Marginal ulcers are an acid-related complication of laparoscopic Roux-en-Y gastric bypass. Few cases of acute perforation have been described, and there are few reports on viable surgical management. This case report demonstrates a two-step surgical procedure for treating a perforated late marginal ulcer in a patient with sepsis.
PRESENTATION OF CASE
A 39-year-old smoker presented to the emergency department six years after undergoing a Roux-en-Y gastric bypass. Diagnostic findings revealed ascites and changes in intestinal calibre, indicating the need for surgery. Intraoperatively, a perforated marginal ulcer covered by the liver was observed. Given the extent of the perforation and the patient's increased instability, discontinuity resection was performed. After stabilisation and improvement in the nutritional status, the gastrojejunostomy was restored nine weeks later.
DISCUSSION
Treatment of Marginal ulcers is controversial, with no clear guidelines. However, severe complications require endoscopic or surgical treatment. The literature considers three main surgical treatment options for perforated marginal ulcers: surgical repair, surgical anastomotic revision, and gastric bypass reversal. Complicated situations, significant intraoperative findings, and unstable patients require tailored approaches.
CONCLUSION
A two-step procedure with discontinuity resection for damage control surgery, patient stabilisation, and improvement of nutritional status, followed by elective continuity restoration with a new gastrojejunostomy, is considered feasible in critically ill patients.

BACKGROUND/AIMS
: Bismuth-based quadruple therapy (BQT) is a treatment option for clarithromycin-resistant (HP) infection. The aim of this study was to compare the efficacy of 7-day BQT with that of 14-day BQT as first-line treatment for clarithromycin-resistant HP infection.
METHODS
: A total of 162 treatment-naïve patients with peptic ulcer disease and clarithromycin-resistant HP infection confirmed by real-time polymerase chain reaction (RT-PCR) were enrolled. The enrolled patients were prospectively randomized to receive BQT for either 7 or 14 days of treatment. Eradication of HP infection was assessed using a C-urea breath test. Eradication and adverse event rates of the two groups were assessed.
RESULTS
: The overall eradication rates in the intention-to-treat (ITT) and per-protocol (PP) analyses were 83.0% (95% confidence interval [CI], 77.2% to 88.9%; 132/159) and 89.8% (95% CI, 84.9% to 94.7%; 132/147), respectively. The eradication rates in the ITT analysis were 79.0% (64/81) in the 7-day group and 87.2% (68/78) in the 14-day group (p=0.170). The eradication rates in the PP analysis were 86.5% (64/74) in the 7-day group and 93.2% (68/73) in the 14-day group (p=0.182). Clinically significant adverse events occurred in 18.2% of patients. There was no statistically significant difference in the rates of individual or all adverse events between the two groups.
CONCLUSIONS
: Both 7-day and 14-day BQT were effective and safe as first-line therapy for HP infections identified as resistant to clarithromycin by RT-PCR. For clarithromycin-resistant HP infections, 7-day BQT may be sufficient as first-line therapy.

Anaprazole sodium enteric-coated tablet is a novel proton pump inhibitor which has been approved for the treatment of duodenal ulcer. The aim of this study is to provide reliable information for the design of an optimal dosage regimen. Population pharmacokinetics and exposure-response models were integrated to evaluate the pharmacokinetic parameters and covariates of Anaprazole and its metabolite M21-1, and subsequently provided dosage suggestions based on clinical trials and simulation data. A pharmacokinetic model incorporating two-compartment for the parent drug and one-compartment for the metabolite, with both first-order and zero-order mixed absorption was used to describe the pharmacokinetics of Anaprazole and M21-1. Age emerged as a significant covariate affecting the elimination rate constant of M21-1, with clearance decreasing as age advances. No correlation was observed between the pharmacokinetics of Anaprazole or M21-1 and the adverse reactions under the current dosages. BMI might be the influence factor of the mild gastrointestinal adverse reactions. Meanwhile, Anaprazole had a good healing rate (94.0 %) in duodenal ulcer patients and the exposure-response analysis indicated that the cured results were not influenced by the exposure parameters of parent drug or metabolite. In conclusion, the drug is safe when dosing between 20 and 100 mg once a day.

OBJECTIVE
To improve the biological and toxicological properties of Mefenamic acid (MA), the galactosylated prodrug of MA named MefeGAL was included in polymeric solid dispersions (PSs) composed of poly(glycerol adipate) (PGA) and Pluronic® F68 (MefeGAL-PS). MefeGAL-PS was compared with polymeric solid formulations of MA (MA-PS) or a mixture of equal ratio of MefeGAL/MA (Mix-PS).
METHODS
The in vitro and in vivo pharmacological and toxicological profiles of PSs have been investigated. In detail, we evaluated the anti-inflammatory (carrageenan-induced paw edema test), analgesic (acetic acid-induced writhing test) and ulcerogenic activity in mice after oral treatment. Additionally, the antiproliferative activity of PSs was assessed on in vitro models of colorectal and non-small cell lung cancer.
RESULTS
When the PSs were resuspended in water, MefeGAL's, MA's and their mixture's apparent solubilities improved due to the interaction with the polymeric formulation. By comparing the in-vivo biological performance of MefeGAL-PS with that of MA, MefeGAL and MA-PS, it was seen that MefeGAL-PS exhibited the same sustained and delayed analgesic and anti-inflammatory profile as MefeGAL but did not cause gastrointestinal irritation. The pharmacological effect of Mix-PS was present from the first hours after administration, lasting about 44 hours with only slight gastric mucosa irritation. In-vitro evaluation indicated that Mix-PS had statistically significant higher cytotoxicity than MA-PS and MefeGAL-PS.
CONCLUSIONS
These preliminary data are promising evidence that the galactosylated prodrug approach in tandem with a polymer-drug solid dispersion formulation strategy could represent a new drug delivery route to improve the solubility and biological activity of NSAIDs.

Gastric ulcer is a common disease affecting pigs worldwide, with a prevalence reported as high as 93%. The cause of porcine gastric ulcer is multifactorial, with Helicobacter suis (H. suis) being considered as the primary pathogenic factor. To date, prevalence of H. suis resulting in porcine gastric ulcer in Taiwan has not been investigated. In this study, we collected 360 pig stomachs from the slaughterhouses. In addition, stomach tissues from the 88 diseased pigs submitted for necropsy were divided into symptomatic and asymptomatic groups. Gastric lesions were scored, and polymerase chain reaction was used to determine the occurrence of gastric ulcer and the prevalence of H. suis. The positive rate of H. suis in the samples from slaughtered pigs was 49.7%, and both infection of H. suis and the presence of gastric lesions were prone to occur in autumn. The positive rates of H. suis infection in the symptomatic and asymptomatic groups were 59.1% and 31.8%, respectively. Moreover, the proportion of the samples with gastroesophageal ulcer in the symptomatic group was 68.2%, predominantly observed in growing pigs. The incidence of the samples from the slaughterhouses with gastroesophageal erosion to ulceration revealed a significant difference between H. suis -infected and H. suis -uninfected pigs; however, there is no significant difference in the samples of diseased pigs. In conclusion, H. suis infection was associated with gastric ulcer in slaughtered pigs, but it was not the primary cause of gastroesophageal ulcer in diseased pigs with clinical symptoms.

Review
Functional dyspepsia is defined as persistent symptoms of postprandial bloating, early satiety, or pain in the center of the upper abdomen, without findings on upper endoscopy such as peptic ulcer disease to explain these symptoms. It is common, affecting up to 30% of the global population, but it often goes undiagnosed for years. There are 2 subtypes: epigastric pain syndrome (burning and pain) and postprandial distress syndrome (bloating and satiety). The authors discuss how to diagnose and treat both subtypes.
