Complementary Therapeutic Effect of Fecal Microbiota Transplantation in Ulcerative Colitis after the Response to Anti-Tumor Necrosis Factor Alpha Agent Was Lost: A Case Report.

In patients with ulcerative colitis (UC), the development of an antidrug antibody (ADA) to anti-tumor necrosis factor (TNF)α agent is a crucial problem which aggravates the clinical course of the disease, being cited as one of the most common causes for discontinuing anti-TNFα treatment. This is due to ADA eventually causing secondary LOR, leading to discontinuation of anti-TNFα treatment. Recently, research on the microbiome and relationship between worsening UC and dysbiosis has been conducted.

Effect of altered gene expression in lipid metabolism on cognitive improvement in patients with Alzheimer's dementia following fecal microbiota transplantation: a preliminary study.

Background: The brain-gut axis has emerged as a potential target in neurodegenerative diseases, including dementia, as individuals with dementia exhibit distinct gut microbiota compositions. Fecal microbiota transplantation (FMT), the transfer of fecal solution from a healthy donor to a patient, has shown promise in restoring homeostasis and cognitive enhancement.

Objective: This study aimed to explore the effects of FMT on specific cognitive performance measures in Alzheimer's dementia (AD) patients and investigate the relationship between cognition and the gut microbiota by evaluating changes in gene expression following FMT.

Role of Probiotics in Preventing Carbapenem-Resistant Colonization in the Intensive Care Unit: Risk Factors and Microbiome Analysis Study.

Older patients with multiple comorbidities often necessitate prolonged hospital stays and antibiotic treatment in the intensive care unit (ICU), leading to a rise in multidrug-resistant organisms like carbapenem-resistant (CRE). This study examined risk factors for carbapenem-resistant Enterobacteriaceae colonization in the ICU and assessed probiotics' preventive role. In this single-center, retrospective study, 9099 ICU patients were tested for stool CRE culture from March 2017 to April 2022.

Effect of a Proton Pump Inhibitor on the Duodenum Microbiome of Gastric Ulcer Patients.

The gut microbiota are regarded as a functional organ that plays a substantial role in human health and disease. Proton pump inhibitors (PPIs) are widely used in medicine but can induce changes in the overall gut microbiome and cause disease-associated dysbiosis. The microbiome of the duodenum has not been sufficiently studied, and the effects of PPIs on the duodenal microbiome are poorly understood.

A prospective non-randomized comparative study was performed with 48 patients.

Long-term prognosis of curative endoscopic submucosal dissection for early colorectal cancer according to submucosal invasion: a multicenter cohort study.

Background: Endoscopic submucosal dissection (ESD) can provide a high en bloc resection rate and has been widely applied as curative treatment for early colorectal cancer (ECC). However, surgical treatment is occasionally required, and reports on the long-term prognosis of ESD are insufficient. This study aimed to investigate the long-term outcomes of ECC removal by ESD, including local recurrence and metastasis.

Fecal microbiota transplantation can improve cognition in patients with cognitive decline and infection.

After fecal microbiota transplantation (FMT) to treat infection (CDI), cognitive improvement is noticeable, suggesting an essential association between the gut microbiome and neural function. Although the gut microbiome has been associated with cognitive function, it remains to be elucidated whether fecal microbiota transplantation can improve cognition in patients with cognitive decline. The study included 10 patients (age range, 63-90 years; female, 80%) with dementia and severe CDI who were receiving FMT.

Prognosis of incompletely resected small rectal neuroendocrine tumor using endoscope without additional treatment.

Background: In recent years, the incidence of rectal neuroendocrine tumors (NET)s has markedly increased due to the widespread use of screening colonoscopy. However, many patients are referred from local clinics after undergoing conventional endoscopic mucosal resection (EMR) for polyps without perceived NET, with a pathological report of incomplete resection. We evaluated the prognosis of incompletely resected small rectal NET without additional endoscopic resection for small rectal NET less than 10 mm in diameter present within the submucosal layer showing good prognosis, due to its rare metastatic potential.

Hemostatic efficacy and safety of the hemostatic powder UI-EWD in patients with lower gastrointestinal bleeding.

Background And Aims: Acute lower gastrointestinal bleeding (LGIB) is a common cause of emergency hospitalization and may require readmission for re-bleeding. Recently, a novel endoscopic hemostatic powder (UI-EWD/Nexpowder™, Nextbiomedical, Incheon, South Korea) was developed and applied for the control of LGIB. The aim of this study was to evaluate the hemostatic efficacy and long-term safety of UI-EWD in LGIB.

The first report on effect of fecal microbiota transplantation as a complementary treatment in a patient with steroid-refractory Cronkhite-Canada syndrome: A case report.

Rationale: Cronkhite-Canada syndrome (CCS) is a rare non-hereditary disease of unknown etiology that is characterized by the appearance of multiple polyps in the entire gastrointestinal (GI) tract, except in the esophagus, with GI and non-GI symptoms. Various factors are associated with the pathogenesis of CCS. Immune dysregulation has been discussed as one of the pathogeneses of CCS, and dysbiosis of the gut microbiota can affect the immune system.

Cognitive function improvement after fecal microbiota transplantation in Alzheimer's dementia patient: a case report.

After fecal microbiota transplantation (FMT) to treat infection (CDI), cognitive improvement is noticeable, suggesting an essential association between the gut microbiome and neural function. Although it is known that the gut microbiome is linked with cognitive function, whether FMT may lead to cognitive improvement in patients with neurodegenerative disorders remains to be elucidated. We present the case of a 90-year-old woman with Alzheimer's dementia and severe CDI who underwent FMT.

Clinical Significance of Residual Nonrectal Inflammation in Ulcerative Colitis Patients in Clinical Remission.

Background/aims: The treatment goal of ulcerative colitis (UC) has been changed to achieve endoscopic remission (ER). However, there is insufficient clinical evidence to determine whether a step-up treatment should be performed to achieve ER in clinical remission (CR) without ER, and there are inadequate data on the need to consider the distribution and severity of residual inflammation. This retrospective study aimed to evaluate the prognostic significance of the distribution and severity of residual inflammation in UC patients in CR.

What is the appropriate cut-off value of CRP to predict endoscopic remission in patients with ulcerative colitis in clinical remission?

Purpose: Noninvasive markers for predicting endoscopic remission (ER) in patients with ulcerative colitis (UC) who are in clinical remission (CR) are important for the determination of appropriate treatment modality. C-reactive protein (CRP) is a surrogate marker for assessing disease activity, albeit with a low sensitivity and specificity when the cut-off value is 0.3 or 0.

Comparison of survival outcomes of alcohol-related hepatocellular carcinoma with or without liver cirrhosis; a ten-year experience.

We evaluated overall survivals (OSs) of alcohol-related hepatocellular carcinoma (HCC) patients without LC compared to those with LC.Between 2005 and 2015, 1343 patients were initially diagnosed as having HCC in our hospital. Of these, 186 alcohol-related HCC patients were enrolled in this study, and their medical records were retrospectively analyzed.

Comparison of the Clinical Outcomes of Suprapapillary and Transpapillary Stent Insertion in Unresectable Cholangiocarcinoma with Biliary Obstruction.

Background And Aims: To prevent stent migration, transpapillary stent placement has been recommended for the endoscopic treatment of malignant hilar biliary stricture. However, recent studies have suggested that placement above the papilla achieves better results, because it is believed to prevent reflux and prolong stent patency. The aim of this study was to compare the efficacy and safety aspects of transpapillary and suprapapillary stent placement.
