The risk factors for the cooccurrence of head and neck cancer and that of gastric cancer in patients with ESCC differ. This information will likely be useful for managing patients who have been treated with ER for ESCC and who possess carcinogenic potential throughout the upper gastrointestinal tract.

<b><i>Background:</i></b> Gastrointestinal bleeding (GIB) is one of the most common medical emergencies. We investigated the overall mortality after GIB in our institute and analyzed the prognostic factors in upper GIB (UGIB) and lower GIB (LGIB) separately. <b><i>Summary:</i></b> Between January 2010 and December 2018, 190 patients diagnosed with GIB in our hospital were retrospectively enrolled. Clinical records and biological data were collected. Risks for rebleeding and in-hospital mortality were assessed by a logistic regression analysis. Overall, the rebleeding rate and in-hospital mortality were 22.6 and 7.6%, respectively. GIB itself was not the direct cause of death in any cases. While older age (&#x3e;65 years) was a significant risk factor for rebleeding in UGIB with an OR of 6.1 and 95% CI of 1.3–29.1, a poorer performance status (PS; ≥3) was a strong risk factor for rebleeding in LGIB, with an OR of 11.8 and 95% CI of 1.7–83.8. Poor PS and tachycardia (&#x3e;100/min) were significantly associated with mortality in both UGIB and LGIB. In contrast, hypoalbuminemia (&#x3c;3.0 g/dL) was associated with the mortality in LGIB alone. <b><i>Key Messages:</i></b> There were considerable differences in the risk factors for rebleeding and in-hospital mortality between UGIB and LGIB. The overall in-hospital mortality was 7.9% after GIB, including that a substantial portion of patients with GIB died from systemic complications after successful endoscopic hemostasis. Physicians need to diligently perform systematic treatment for GIB, which may be particularly important in societies of advancing aging, like Japan.

Objects Ultrashort‐segment Barrett’s esophagus (USSBE; length of <1 cm) is very frequently diagnosed in Japan, but the cancer risk of USSBE is unknown. In this study, by retrieving endoscopic images, we retrospectively investigated the incidence of esophageal adenocarcinoma (EAC) by the grade of Barrett’s esophagus (BE) and compared the findings with those of gastric cancer by the degree of endoscopic gastric atrophy in the same population. Methods Among consecutive participants who had undergone endoscopy for an annual health checkup in 2014, the 9121 who had received at least one follow‐up endoscopy by December 2020 were enrolled in this study. Using the retrieved endoscopic images, we retrospectively evaluated BE and gastric atrophy. Information on the subsequent occurrence of EAC and gastric cancer as of December 2020 was also collected. The incidence of cancer by the extent of BE and gastric atrophy was calculated and expressed as the percentage per year. Results On reviewing the endoscopic image in 2014, 4190 (45.9%) were found to have been diagnosed with BE, of whom 3318 (36.4%) were judged to have USSBE. During an observation period of 54.1 (17.9) months, 89 gastric cancers and only two EACs were identified. The incidence of EAC in USSBE was 0.0068%/year, which was nearly as low as the incidence of gastric cancer in atrophy‐free patients (0.0068% vs. 0.0059%/year). Conclusions Although the prevalence of USSBE is quite high (36.4%), the incidence of EAC in USSBE is very low (0.0068%/year). Accordingly, USSBE can be excluded from targets for endoscopic surveillance in Japan.

Purpose Self-stigma negatively influences self-esteem, quality of life, self-efficacy, treatment adherence, and recovery in psychiatric patients. By revealing personality traits that influence self-stigma, we can gain useful knowledge for the management of self-stigma. A previous meta-analysis indicated that patients with schizophrenia have higher scores on the Autism-Spectrum Quotient (AQ) than healthy controls. However, the relationship between autistic symptoms and self-stigma in patients with schizophrenia spectrum disorders remains unclear. Therefore, the present study aimed to reveal the association between autistic symptoms and self-stigma in patients with schizophrenia spectrum disorders. Patients and Methods We recruited 127 patients with schizophrenia spectrum disorders (schizophrenia, schizoaffective disorder, and delusional disorder). We assessed participants’ self-stigma and autistic symptoms using the Internalized Stigma for Mental Illness (ISMI) scale and the Autism-Spectrum Quotient (AQ), respectively. The differences in the scores of ISMI and AQ according to patient characteristics were investigated. Multiple regression analysis controlling for age and gender was performed to determine the relationship between the total scores on the AQ and IMSI scale. Results Female patients showed a higher level of self-stigma than males. Unmarried patients showed a significantly higher score on the AQ than married patients. Multiple regression analysis adjusted for age and gender indicated that the total score on AQ might be a predictor of the overall rating on ISMI in patients with schizophrenia spectrum disorders. Conclusion This study is the first to reveal the association between autistic symptoms and self-stigma in patients with schizophrenia spectrum disorders. Our results highlight the importance of considering autistic symptoms in the assessment and management of self-stigma in patients with schizophrenia spectrum disorders.

INTRODUCTION: Proton pump inhibitors (PPIs) are associated with the onset of Clostridioides difficile infection (CDI). Although a new potassium-competitive acid blocker, vonoprazan, consistently shows a more potent acid inhibitory effect in comparison to PPIs, the risk of CDI in vonoprazan-treated patients relative to those treated with PPIs is unknown. In this retrospective case-control study, using a nationwide hospital-based administrative database in Japan, we investigated the association of the onset of CDI in patients treated with vonoprazan. METHODS: A CDI case was defined as a case in which a patient was diagnosed and treated for CDI. For each CDI case, 3 non-CDI patients were extracted as controls. Information on the usage of acid suppressants in the 2 months before the onset of CDI and other confounding factors was collected. Relative associations of gastric acid suppressants with the onset of CDI were estimated. RESULTS: A total of 4,466 CDI cases and 13,220 of non-CDI controls were extracted. A multivariate conditional regression analysis revealed that PPI or vonoprazan use was modestly, but significantly associated with CDI (odds ratio [95% confidence interval]: PPI, 1.3 [1.2–1.4]; vonoprazan, 1.4 [1.2–1.7]). With PPI users as a reference, vonoprazan did not show a stronger association with CDI (odds ratio [95% confidence interval]: 1.07 [0.91–1.26]). DISCUSSION: We found a significant positive association between vonoprazan use and CDI; however, the magnitude of the association was not beyond that in PPI users. This is the first report on any potential adverse effects of vonoprazan.

Background Various molecular-targeted therapeutic agents that inhibit cytokines and immune checkpoints are used in clinical practice. Some of these biologics that control immunity, such as anti-interleukin-17, anti-programmed cell death protein-1, and anti-cytotoxic T-lymphocyte-associated protein antibodies, affect intestinal immune homeostasis and cause intestinal inflammation. Development of enteritis due to dupilumab (an anti-IL-4Ralpha monoclonal antibody) therapy is not yet reported in the literature. Case presentation A 17-year-old man was administered an injection of dupilumab and continued to receive it for refractory atopic dermatitis. After 3 months of initiating dupilumab therapy, he developed intermittent abdominal pain, tenesmus, and had diarrhea. Colonoscopy examination showed decreased vascularity, mild friability, and erythema in the cecum, part of the ascending colon, sigmoid colon, and rectum without any pathogenic bacteria. Histological examination revealed moderate mixed inflammatory cell infiltration, cryptitis, destruction of the crypt, decreased goblet cells, mucosal erosions, and edema. He was diagnosed with UC and was prescribed oral mesalazine (4800 mg/day) treatment. Within a month of the treatment, his diarrhea improved and the frequency of defecation decreased. Conclusions This is a first report that dupilumab mimicked ulcerative colitis. Careful monitoring for adverse effects with the onset of an intestinal inflammation will be recommended after dupilumab administration.
