Abstract	Background: Gastric cancer remains the fourth leading cause of cancer-related death worldwide. Significant number of gastric cancer patients presented with bleeding. Objective: This study aimed to identify risk factors and overall survival rates of bleeding gastric cancer patients. Methods: This retrospective cohort study was conducted between 2007-2022 at tertiary care center in Thailand. Clinical information, endoscopic findings and histological type were extensively reviewed and were compared between bleeders and non-bleeders. Patients were monitored for at least 5 years. Results: There were 20,981 patients who underwent upper gastrointestinal endoscopy during study period. Total of 201 gastric cancer patients were included in this study, 21 were excluded due to incomplete medical records. 180 gastric cancer patients were included with mean age of 60.5±14.3 years. There were 65 (36.1%) patients with gastrointestinal bleeding. Hypertension and chronic kidney disease were significantly more common in bleeders than non-bleeders (43.1% vs 23.5%, OR2.51, 95%CI 1.14.-5.52, p = 0.022; and 16.9% vs 5.2%, OR2.00, 95%CI 1.56-6.63, p = 0.025, respectively). current H. pylori infection was also significantly more common in bleeders than non-bleeders (84.6% vs. 55.7%, OR 4.39, 95%CI 1.90-10.12, p<0.001). Median overall survival of bleeders was significantly lower than non-bleeders (7±0.93 vs 10±2.10 months, p = 0.001). Conclusions: Bleeding gastric cancer was not an uncommon condition. Majority of patients presented at advanced stage with grave prognosis. Male gender, hypertension, chronic kidney disease, and current H. pylori infection were reliable predictors for bleeding. Early diagnosis and prompt treatment are the key to improve clinical outcome.

Abstract	Background: Helicobacter pylori treatment failure remains a challenging problem. This study aimed to identify predictive factors for successful eradication in patients following treatment failures. Methods: This was a retrospective cohort study. This study included 1,050 dyspeptic patients diagnosed with H. pylori infection at tertiary care center in Thailand between March 2014 and October 2021. Patients' demographic data, endoscopic findings, H. pylori culture, antimicrobial susceptibility testing (AST), treatment regimens and outcomes were analysed. Results: Of 1,050 patients with H. pylori infections, 302 (28.7%) experienced treatment failure (mean age 58.4 years; 44.7% males). AST was performed in 192. Resistance was observed for metronidazole (43.2%), levofloxacin (33.9%), clarithromycin (24%), and amoxicillin (2.1%). There was no tetracycline resistance. Multidrug-resistance (MDR) was significantly more common following treatment failure (45.5% vs. 15.7%, p<0.001). Baseline characteristics were similar between treatment successes and failures. Eradication rates after first-line and second-line regimens were 71.2% and 54.5%, respectively. Medication nonadherence [OR 36.6 (95%CI 8.65-155.03, p<0.001)] and MDR [OR 4.49 (95%CI 2.29-8.81, p<0.001)] were associated with treatment failure. Over time, resistance increased for metronidazole, levofloxacin, and clarithromycin, while eradication rates with triple therapy declined. Tailored antibiotic therapy [OR 4.92 (95%CI 1.61-14.99, p = 0.005)] and a regimen including 4-times-daily dosing of amoxicillin (2 grams/day) [OR 3.05 (95%CI 1.10-8.41, p = 0.032)] were significantly associated with treatment success after first-line failure. Eradication rates when using tailored therapy and 4-times-daily dosing of amoxicillin (2 grams/day) were 91.1% and 89.4%, respectively. Performing AST before first-line therapy resulted in the highest cure rates. AST performed after multiple treatment failures was also associated with higher eradication rates compared with the group without AST (94.4% vs. 50%,p = 0.008). Conclusions: AST either before or after treatment failure correlated with a higher proportion of successful eradication. Nonadherence and the MDR infections predicted treatment failure. Tailored therapy and 4-times-daily dosing of amoxicillin after treatment failure were likely to be successful.

Abstract	Background and aim: Coronavirus disease 19 (COVID-19) has caused over 200 000 deaths worldwide. Thailand announced the first confirmed case outside mainland China in January 2020. The disease also spread widely across Association of Southeast Asian Nations (ASEAN). Gastrointestinal manifestations could be presenting symptoms of COVID-19. This study aimed to determine the prevalence of gastrointestinal manifestations of COVID-19 patients in Thailand and review important aspects of this disease in ASEAN. Methods: Thai patients diagnosed with COVID-19 at Thammasat University Hospital, Thailand, were evaluated between 1 January 2020 and 30 April 2020. Patients' data, clinical presentation, exposure risk, past medical history, laboratory results, and treatment outcomes were extensively reviewed. Results: A total of 352 COVID-19 tests were performed, and 40 patients with positive tests were studied. The mean age was 30.5 years, and 55% were female. Most (82.5%) had no underlying diseases. Comorbidities were associated with severe COVID-19 (odds ratio [OR] 29.93; 95% confidence interval [CI] 2.31-388.40, Conclusions: Gastrointestinal manifestations in COVID-19 patients are common symptoms and can occur anytime during the disease course. Patients presenting with only gastrointestinal symptoms should raise clinical suspicion for COVID-19 in areas with high disease incidence. Clinically severe COVID-19 was associated with comorbidities and diarrhea.

Abstract	Background: Gastric cancer ranks as a leading cause of cancer deaths worldwide. Information of prognostic factors related to gastric cancer are limited. Aim: This study aimed to gather clinical data and prevalence of prognostic factors related to gastric adenocarcinoma in Thailand. Methods and results: This retrospective cohort study was conducted at Thammasat University Hospital, Thailand between January 2010 and July 2018. Gastric adenocarcinoma patients were enrolled and followed up for at least 5 years. Total of 210 gastric tumor patients were enrolled. One hundred patients were diagnosed with gastric adenocarcinomas (57 men and 43 women, mean age = 61.1 years). The leading presenting symptoms were weight loss (65%), followed by dyspepsia (54%) and UGI bleeding. Common clinical manifestations were thrombocytosis (26%), followed by syndrome of inappropriate antidiuretic hormone (SIADH; 15%). Eosinophilia was present in early cancer (25.0% vs 6.5%, P = .123), while SIADH and thrombocytosis were more common in advanced stages (16.3% vs 0%, P = .602, and 28.3% vs 0%, P = .108, respectively). SIADH was significantly related to reduced 1-year survival rate compared to normal serum sodium levels (21.4% vs 71.4%, OR 0.109, 95% CI 0.024-0.497, P = .004). Five-year survival rates were worse in patients with SIADH, but better in patients with eosinophilia compared to patients without these conditions (0% vs 27.8%, P = .058 and 20.0% vs 7.8%, P = .375, respectively). Conclusion: Thrombocytosis and SIADH were common in gastric cancer. SIADH was significantly correlated with poor 1-year survival. These clinical manifestations might be useful for predicting gastric cancer prognosis.

Abstract	Introduction: Association of Southeast Asian Nations (ASEAN) countries have high Methods: This retrospective cohort study was conducted between 2007 and 2022 at a tertiary care center in Thailand. All clinical information, endoscopic findings, and histological types were extensively reviewed. Furthermore, all qualified studies in ASEAN published in PubMed and Scopus between 2000 and 2022 were extracted and thoroughly analyzed. Young female GC patients are defined as those ≤50 years of age. Results: A total of 98 Thai female GC patients were included, with a mean age of 58.99 ± 14 years; 70.4% were elderly women. The common presenting symptoms were weight loss (69.4%) and dyspepsia (68.4%). Younger female GC patients had significantly more common diffuse-type GC than elderly female GC patients (82.8% vs. 53.6%, Conclusion: GC in women is not uncommon in ASEAN and presents at an advanced stage with a grave prognosis. This study showed that ASEAN countries with the highest disease burden were Indonesia, Thailand, and Singapore. Overall, survival rates for female GC patients in ASEAN countries were relatively low, highlighting the need for proactive measures such as intensive
