Abstract
Background: Gastrointestinal bleeding is one of the consequences of COVID-19, which is associated with increased hospitalization and patient mortality. This study was conducted to determine the prevalence of endoscopic findings and the outcome of gastrointestinal bleeding in patients with COVID-19 who were hospitalized from September to December 2019 in Al-Zahra Hospital, Isfahan.
Methods: In this cross-sectional study, out of 5800 patients who were admitted to Al-Zahra Hospital in Isfahan from September to December 2019 due to COVID-19 (according to the positive PCR test result), 87 patients who underwent endoscopy due to upper gastrointestinal bleeding by a skilled gastroenterologist, were selected and studied. Demographic characteristics, underlying diseases, use of anticoagulants, and laboratory findings were studied and evaluated and finally, the disease was evaluated and compared based on endoscopic findings.
Results: Based on the results obtained from this research, the patients with endoscopic lesions had higher average age (P=0.041), lower blood oxygen saturation percentage (P=0.028), and higher bleeding intensity (P=0.018). The frequency of using anticoagulant drugs in the group whose endoscopy results were abnormal was higher but insignificant. Hemoglobin, platelet, lymphocyte, and CRP levels were higher in the group whose endoscopy was normal, and NLR, LDH, and D-dimer levels were higher in the group whose endoscopy was abnormal (P<0.050). Three people (11.55%) from the group with normal endoscopy and 18 people (29.5%) from the group with abnormal endoscopy died, but the frequency of death was not significantly different between the two groups (P=0.070).
Conclusion: The findings of the present study showed that the COVID patients with upper gastrointestinal bleeding who had endoscopic lesions had significant differences in some characteristics such as age, bleeding intensity, and blood oxygen saturation percentage with patients with normal endoscopy. Also, the frequency of death in patients with endoscopic lesions was relatively higher. Therefore, COVID patients with gastrointestinal bleeding should undergo endoscopy as soon as possible and necessary measures should be taken to control and prevent gastrointestinal bleeding.

Abstract
Background: Most people often complain of abdominal bloating. The present study was designed and conducted with the purpose of examining the effect of sequential treatment of Metronidazole and Probiotics, and Probiotics alone in reducing the severity of symptoms of functional bloating.
Methods: The present study was a randomized clinical trial that was carried out from March 2022 until June 2023 in Isfahan and Khurshid Hospital. The studied population were suffering from flatulence and were diagnosed with functional bloating by a gastroenterologist based on Rome III criteria. Then they entered one of the two study groups in a double-blind manner. The first group was treated with Metronidazole for two weeks and then with Probiotic for two weeks. The second group was treated with Probiotic for four weeks. The severity of patients' bloating was measured by a 4-question questionnaire in five stages: before the start of the study, two weeks after, four weeks after, six weeks after, eight weeks after and 12 weeks after the start of the study.  Finally, the obtained information was entered into SPSS software version 24 Repeated measures ANOVA was used to investigate the relationship between variables.
Results: After collecting the data, 43 patients in the first group and 44 patients in the second group were examined. 72.1% of the first group were women and 27.9% were men. In group two, this ratio was 72.7% for women and 27.3% for men. In this intervention, it was seen that in the 1st group, the average severity of bloating decreased until the end of the eighth week and after the second week of drug treatment, and then increased. In the second group, the average intensity of bloating decreased until the end of the fourth week and at the same time as the end of drug treatment, and then increased.
Conclusion: It was shown that in the study, the effect of this combined treatment had a greater effect in reducing the severity of functional bloating among patients with functional bloating.
