Risk of stricture after endoscopic submucosal dissection in the cervical esophagus and efficacy of local steroid injection for stricture prevention.

BACKGROUND AND AIMS: There is a high incidence of stricture after endoscopic submucosal dissection (ESD) for cervical esophageal cancer. We aimed to elucidate the risk factors for stricture and evaluate the efficacy of steroid injection for stricture prevention in the cervical esophagus. METHODS: We retrospectively analyzed 100 patients who underwent ESD for cervical esophageal cancer to: (1) identify the factors associated with stricture among patients who did not receive steroid injection; (2) compare the incidence of stricture between patients with and without steroid injection. RESULTS: Among 48 patients who did not receive steroid injection, there were significant differences in tumor size (P = .026), resection time (P = .028), and circumferential extent of the mucosal defect (P = .005) between patients with stricture (n = 5) and without stricture (n = 43). Compared with patients without steroid injection, patients with steroid injection had a significantly lower incidence of stricture when the post-ESD mucosal defect was < 3/4 and ≥ 1/2 (40% versus 8%, P = .039). As for the patients with a post-ESD mucosal defect of ≥ 3/4 (n = 13), local steroid injection was performed for all the patients, and 6 patients (46%) developed stricture. CONCLUSIONS: Patients who underwent ≥ 1/2 circumferential resection were at high risk of cervical esophageal stricture. Steroid injection had a stricture-prevention effect in patients with < 3/4 and ≥ 1/2 circumferential resection, but seemed to be insufficient in preventing stricture in patients with ≥ 3/4 circumferential resection.

Improved Glycemic Control through Robot-Assisted Remote Interview for Outpatients with Type 2 Diabetes: A Pilot Study.

Background and Objectives: Our research group developed a robot-assisted diabetes self-management monitoring system to support Certified Diabetes Care and Education Specialists (CDCESs) in tracking the health status of patients with type 2 diabetes (T2D). This study aimed to evaluate the impact of this system on glycemic control and to identify suitable candidates for its use. Materials and Methods: After obtaining written informed consent from all participants with T2D, the CDCESs conducted remote interviews with the patients using RoBoHoN. All participants completed a questionnaire immediately after the experiment. HbA1c was assessed at the time of the interview and two months later, and glycemic control status was categorized as either "Adequate" or "Inadequate" based on the target HbA1c levels outlined in the guidelines for adult and elderly patients with type 2 diabetes by the Japan Diabetes Society. Patients who changed their medication regimens within the two months following the interview were excluded from the study. Results: The clinical characteristics of the 28 eligible patients were as follows: 67.9 ± 14.8 years old, 23 men (69%), body mass index (24.7 ± 4.9 kg/m2), and HbA1c levels 7.16 ± 1.11% at interview and two months later. Glycemic control status (GCS) was Adequate (A) to Inadequate (I): 1 case; I to A: 7 cases; A to A good: 14 cases; I to I: 6 cases (p-value = 0.02862 by Chi-square test). Multiple regression analyses showed that Q1 (Did RoBoHoN speak clearly?) and Q7 (Was RoBoHoN's response natural?) significantly contributed to GCS, indicating that the naturalness of the responses did not impair the robot-assisted interviews. The results suggest that to improve the system in the future, it is more beneficial to focus on the content of the conversation rather than pursuing superficial naturalness in the responses. Conclusions: This study demonstrated the efficacy of a robot-assisted diabetes management system that can contribute to improved glycemic control.

Predictors of technical difficulty for trainees in esophageal endoscopic submucosal dissection.

BACKGROUND: Esophageal endoscopic submucosal dissection (ESD) is technically challenging, especially for trainees, and requires a safe training system. This study aimed to identify predictors of technical difficulty facing trainees performing esophageal ESD to establish such system. METHODS: This was a single-center retrospective study of patients with esophageal cancer who underwent ESD performed by trainees between January 2010 and August 2022. Technical difficulties were defined as muscularis propria exposure and long procedure time (≥ 90 min). Factors associated with these technical difficulties were investigated. RESULTS: A total of 798 lesions in 721 patients were evaluated. Muscularis propria exposure occurred in 298 lesions (37.3%), including 10 perforations (1.3%). The procedure time was ≥ 90 min in 134 lesions (16.8%). In the multivariate analysis, tumor size ≥ 20 mm, tumors ≥ 1/2 of the circumference, and those close to previous treatment scars significantly increased the incidence of both difficulties, whereas tumors in the upper esophagus significantly decreased this incidence. Furthermore, female sex and tumors in the left wall were independent predictors of muscularis propria exposure, and elevated morphology was an independent predictor of long procedure time. Muscularis propria exposure and long procedure time occurred in more than half of the cases with three or more predictors of each difficulty. CONCLUSIONS: Large tumors and tumors close to previous treatment scars increase technical difficulties for trainees in esophageal ESD. Conversely, tumors in the upper esophagus reduce these difficulties. These results enable us to predict the difficulty level preoperatively and select appropriate cases in stepwise training.

Support nursing researchers' need from academic societies during COVID-19: A cross-sectional survey.

The activities of nursing researchers have been constrained by the COVID-19 pandemic. Therefore, this study aimed to investigate the types of support and related factors that nursing researchers hope to receive from academic societies during the pandemic and to obtain suggestions for the role of academic societies in supporting nursing researchers and expanding research. An online survey was conducted with 1532 Japan Academy of Nursing Science members. The survey included 19 items of potential support from the society during the COVID-19 pandemic as well as open-ended questions. Data were analyzed statistically and qualitatively. For 9 of the 19 items, over 50% of respondents reported that they "needed" or "very much needed" support. Multivariate analysis results showed that younger respondents and those with family members requiring care were significantly more likely to report needs for some items. In the open-ended comments, there were several suggestions for activities, including "Lobbying for revision of regulations on research implementation." Nursing researchers expressed needs for support that reflect their demographic characteristics and situations, including collaboration across organizations and securing research-promotion and skill-development opportunities online.

[A case of rectovaginal metastasis 6 years after initial resection of extra-gastrointestinal stromal tumor of vulvar origin].

A 53-year-old woman who had undergone excision of KIT-positive extra-gastrointestinal stromal tumor (EGIST) of the vulva 6 years ago presented to our hospital due to a positive fecal occult blood test. Colonoscopy revealed a submucosal tumor in the rectum ventral side. In addition, computed tomography and magnetic resonance imaging revealed a tumor in the rectovaginal septum. For diagnostic and therapeutic purposes, the tumor was resected via the perineal approach. The resected specimen analysis revealed a KIT-positive gastrointestinal stromal tumor (GIST). Following immunopathological and genetic mutation identifications, GIST of the rectovaginal septum from vulva EGIST metastasis was diagnosed. It is important to consider primary GIST and metastatic GIST as differential diagnoses in the case of a rectal submucosal tumor detected by endoscopy.

[Hematemesis due to rupture of splenic artery pseudoaneurysm in association with segmental arterial mediolysis:a case report].

A gastric ulcer was detected in a 54-year-old man who underwent upper gastrointestinal endoscopy for hematemesis. An abdominal contrasted computed tomography scan detected a splenic artery aneurysm adjacent to the gastric wall. Endoscopic hemostasis was thought to be risky owing to possible rupture of the aneurysm. Rupture of a splenic artery pseudoaneurysm due to segmental arterial mediolysis (SAM) was diagnosed by abdominal angiography, and subsequently transcatheter arterial embolization was performed. In cases of upper gastrointestinal hemorrhage, hemostasis is often performed during the emergency endoscopic examination. However, in cases of massive gastrointestinal bleeding, the possibility of a splenic artery aneurysm, in association with SAM, should be recognized. The risk of rupturing the aneurysm should be considered in selecting the most suitable treatment.

Potential role of a novel endoscopic retrieval bag for large colorectal resected specimen: a proof-of-concept study.

Endoscopic submucosal dissection enables en bloc resection of large superficial colorectal neoplasms. However, it is sometimes challenging to retrieve a large resected specimen via the anus without sample fragmentation. A novel "bag-type" retrieval device has been developed to accomplish complete isolation and non-destructive delivery of oversized specimens. This single-center retrospective study was performed to demonstrate the efficacy of this device for large colorectal resected specimens. Among 17 patients, we identified 18 superficial colorectal lesions for which the use of a novel retrieval device (Endo Carry Large Type) was indicated at specimen delivery at a referral cancer institute from March 2021 to July 2022. The median (interquartile range) tumor size was 62.5 (52.0-79.5) mm. Retrieval of 17 (94%) of 18 resected specimens was performed using the Endo Carry Large Type, and 16 (89%) were successfully retrieved without sample fragmentation. The median (interquartile range) retrieval time was 4 (4-8) minutes, and no apparent adverse events were observed. The novel Endo Carry Large Type device can accomplish colorectal specimen retrieval safely and quickly without specimen damage and therefore may contribute to accurate pathological diagnosis.

Development of a Family Support Scale for Diet Therapy for Male Workers with type 2 diabetes.

AIM: Dietary self-care for patients with type 2 diabetes can be improved with family support. The purpose of this study was to develop a scale to assess family support for diet therapy for male workers with type 2 diabetes and to examine its reliability and validity. METHODS: In this cross-sectional study, we collected data from 110 Japanese male workers with type 2 diabetes. Data were analyzed using exploratory factor analysis, reliability testing, and validity testing. RESULTS: The resultant Family Support Scale for Diet Therapy for Male Workers (FSS-DMW) with type 2 diabetes consisted of 31 items and a six-factor structure. The six factors explained 72.9% of the variance, and Cronbach's alpha for the total scale was .964. The scale correlated as expected with the Social Support Scale for Chronic Illness and the dietary subscale of the Japanese version of the Summary of Diabetes Self-Care Activities Measure. CONCLUSION: The FSS-DMW is a reliable and valid measure which can be used to assess family support for diet therapy for male workers with type 2 diabetes and has the potential to be used as a clinical instrument for family guidance.
