BackgroundTransabdominal ultrasonography (US) has been reported to be a useful tool for evaluating ulcerative colitis (UC) although with less well-established data than for Crohn’s disease. This prospective multicenter study aimed to establish the usefulness of US compared with colonoscopy (CS) for assessing disease extent and activity of UC.MethodsAltogether, 173 patients with UC were prospectively enrolled, among whom 156 were eligible for this study. All patients underwent US and CS within 2 days at five facilities. We divided the colon into six segments and examined each segment and the rectum using US and CS. US severity was graded 1–4 regarding bowel wall thickness, stratification, and ulceration. CS severity was also graded 1–4 according to Matts’ endoscopic classification. Concordance between US and CS grades for all colonic segments was analyzed using kappa statistics. US and CS findings were also compared with the clinical disease activity index (CAI) and histological grade using Spearman's correlation coefficient.ResultsThere was moderate concordance between US and CS grades in all colonic segments (weighted κ = 0.55, p < 0.001). Concordance was rated moderate for each colonic segment but only slight for the rectum. The US grade was significantly correlated with the CAI score (r = 0.40, p < 0.001) and histological grade (r = 0.35, p < 0.001).ConclusionsThis prospective multicenter study showed moderate concordance between US and CS for assessing the disease activity of UC. Hence, US may be used more generally for evaluating UC in daily clinical practice.

Background Controversy exists over the preferred technique of preoperative biliary drainage (PBD) in patients with hilar cholangiocarcinoma (HCA). The goal of this retrospective study was to identify the preferred technique of PBD for HCA. Methods A total of 128 consecutive patients with HCA diagnosed between September 1999 and December 2009 who underwent PBD were included in this study. The study compared outcomes of endoscopic nasobiliary drainage (ENBD), endoscopic biliary stenting (EBS), and percutaneous transhepatic biliary drainage (PTBD) in patients with HCA. Results There were no significant differences in preoperative laboratory data, rates of major hepatectomy, or decompression periods among the 3 groups. Complications were significantly more frequent in the EBS group compared with either the ENBD or PTBD group (p < 0.05). Drainage tube occlusion with cholangitis was significantly more common in the EBS group compared with either the ENBD or PTBD group (p < 0.0001). Patients in the PTBD group experienced serious complications including vascular injury (8%) and cancer dissemination (4%). Patients in the ENBD and EBS groups had mild post-endoscopic retrograde cholangiopancreatography pancreatitis (5%). Conversion procedures were significantly more common in the EBS group compared with the ENBD and PTBD groups (p < 0.05). There was no significant difference in postsurgical morbidity or mortality among the 3 groups. Conclusions Drainage tube occlusion with cholangitis was a frequent complication associated with EBS. PTBD was associated with serious complications such as vascular injury and cancer dissemination. ENBD was found to be the most suitable method for initial PBD management in patients with HCA.

The purpose of this study is to compare the efficacy of a single administration of dexamethasone (DEX) on day 1 against DEX administration on days 1–3 in combination with palonosetron (PALO), a second‐generation 5‐HT3 receptor antagonist, for chemotherapy‐induced nausea and vomiting (CINV) in non‐anthracycline and cyclophosphamide (AC) moderately‐emetogenic chemotherapy (MEC). This phase III trial was conducted with a multi‐center, randomized, open‐label, non‐inferiority design. Patients who received non‐AC MEC as an initial chemotherapy were randomly assigned to either a group administered PALO (0.75 mg, i.v.) and DEX (9.9 mg, i.v.) prior to chemotherapy (study treatment group), or a group administered additional DEX (8 mg, i.v. or p.o.) on days 2–3 (control group). The primary endpoint was complete response (CR) rate. The CR rate difference was estimated by logistic regression with allocation factors as covariates. The non‐inferiority margin was set at −15% (study treatment group − control group). From April 2011 to March 2013, 305 patients who received non‐AC MEC were randomly allocated to one of two study groups. Overall, the CR rate was 66.2% in the study treatment group (N = 151) and 63.6% in the control group (N = 154). PALO plus DEX day 1 was non‐inferior to PALO plus DEX days 1–3 (difference, 2.5%; 95% confidence interval [CI]: −7.8%–12.8%; P‐value for non‐inferiority test = 0.0004). There were no differences between the two groups in terms of complete control rate (64.9 vs 61.7%) and total control rate (49.7% vs 47.4%). Anti‐emetic DEX administration on days 2–3 may be eliminated when used in combination with PALO in patients receiving non‐AC MEC. In this study, we evaluated the efficacy of a single administration of dexamethasone (DEX) on day 1 against DEX administration on days 1–3 with palonosetron (PALO), for chemotherapy‐induced nausea and vomiting (CINV) in non‐AC (anthracycline and cyclophosphamide) moderately‐emetogenic chemotherapy (MEC) in the phase III study. Our randomized phase III study successfully demonstrated non‐inferiority of DEX administration only on day 1 compared to days 1–3 when used in combination with PALO during non‐AC MEC.

Background Endoscopic ultrasound (EUS)-guided drainage is widely used to manage pancreatic pseudocysts. Several studies have reported the use of EUS-guided drainage for pancreatic fistula and stasis of pancreatic juice caused by stricture of the pancreatic duct after pancreatic resection. Methods At the authors’ hospital, 262 patients underwent surgery involving pancreatic resection from April 2005 to March 2010. In 90 of these patients (34%), a grade B or C postoperative pancreatic fistula developed that required additional treatment. The authors performed EUS-guided transmural drainage (EUS-TD) for six patients (2.1%) with a pancreatic fistula or dilation of the main pancreatic duct visible by EUS. Percutaneous drainage was provided for 18 patients (6.8%). The success rates for EUS-TD and percutaneous drainage were compared in a retrospective analysis. Results In all six cases, EUS-TD was performed successfully without complications. Five of the six patients were successfully treated with only one trial of EUS-TD. The final technical success rate was 100% for both EUS-TD and percutaneous drainage. Both the short- and long-term clinical success rates for EUS-TD were 100% and those for percutaneous drainage were 61.1 and 83%, respectively. The differences in these rates were not significant (short-term success, P  = 0.091 vs. long-term success, P  = 0.403). However, the time to clinical success was significantly shorter with EUS-TD (5.8 days) than with percutaneous drainage (30.4 days; P  = 0.0013) in the current series. Conclusions The EUS-TD approach appears to be a safe and technically feasible alternative to percutaneous drainage and may be considered as first-line therapy for pancreatic fistulas visible by EUS.

Background: Pancreatic ductal carcinoma (PDC) is one of the most lethal human carcinomas. Expression patterns of some genes may predict gemcitabine (GEM) treatment efficacy. We examined predictive indicators of survival in GEM-treated patients by quantifying the expression of several genes in pre-treatment endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) samples from patients with PDC. Methods: The expressions of human equilibrative nucleoside transporter 1 ( hENT1 ), deoxycitidine kinase, ribonucleoside reductase 1, ribonucleoside reductase 2 and Notch3 in EUS-FNA tissue samples from 71 patients with unresectable PDC were quantified using real-time reverse transcription–polymerase chain reactions and examined for correlations with GEM sensitivity. Results: The log-rank test detected no significant differences in overall survival between GEM-treated patients with low and high mRNA levels of all genes examined. However, low Notch3 mRNA expression was significantly associated with longer overall survival in a multivariate analysis for survival ( P =0.0094). High hENT1 expression level was significantly associated with a longer time to progression ( P =0.039). Interaction tests for GEM administration and hENT1 or Notch3 mRNA expression were statistically significant ( P =0.0054 and 0.0047, respectively). Conclusion: hENT1 and Notch3 mRNA expressions in EUS-FNA specimens were the key predictive biomarkers of GEM effect and GEM sensitivity in patients with unresectable PDC.

Background Endoscopic retrograde cholangiopancreatography (ERCP) and related procedures can cause abdominal pain and discomfort. Two clinical trials have indicated, using the visual analogue scale (VAS) score, that CO 2 insufflation during ERCP ameliorates the suffering of patients without complications, compared with air insufflation. However, differences in patient suffering between CO 2 and air insufflation after ERCP under deep conscious sedation have not been reported. We focused on the gas volume score (GVS) as an objective indicator of gas volume, and designed a multicenter, prospective, double-blind, randomized, controlled study with CO 2 and air insufflation during ERCP. Methods Between March 2010 and August 2010, 80 patients who required ERCP were enrolled and evenly randomized to receive CO 2 insufflation (CO 2 group) or air insufflation (air group). ERCP and related procedures were performed under deep conscious sedation with fentanyl citrate or pethidine and midazolam or diazepam. The GVS was evaluated as the primary endpoint in addition to the VAS score as the secondary endpoint. Results The GVS after ERCP and related procedures in the CO 2 group was significantly lower than that in the air group (0.14 ± 0.06 vs. 0.31 ± 0.11, P  < 0.01), as well as the rate of increase in GVS ([GVS after − GVS before]/[GVS before ERCP and related procedures] × 100) (3.8 ± 5.9 vs. 21 ± 11.1%, P  < 0.01). VAS scores 3 and 24 h after ERCP and related procedures were comparable between the CO 2 and air groups for abdominal pain, abdominal distension, and nausea. Additionally, VAS scores were not correlated with the GVS. Conclusions CO 2 insufflation during ERCP reduces GVS (bowel gas volume) but not the VAS score of suffering compared with air insufflation. Deep and sufficient sedation during ERCP and related procedures is important for the palliation of patients’ pain and discomfort.

Background: Subjective well-being (SWB) is an essential indicator of successful aging. Although social connections enhance SWB among older adults, few interventions have integrated community-based approaches with information and communication technology (ICT). This study evaluated the Chofu–Digital–Choju (CDC) project, a multi-component community intervention fostering in-person and online social connections among community-dwelling older adults in urban Japan. Methods: This quasi-experimental study (January 2022 to March 2024) included community-dwelling older adults aged 65–84 years in Chofu City, Tokyo, Japan. The intervention consisted of online classes, community hubs as local third places, and community events. Baseline and follow-up data were collected using self-administered questionnaires. Propensity score matching (1:1) was used to reduce selection bias, and generalized estimating equations were applied to evaluate the intervention effects. The primary outcome was SWB (Cantril Ladder). The secondary outcomes included social isolation, neighborhood relationships, social participation, health literacy, psychological health, physical activity, and ICT use. Results: Among the 1599 participants who completed both surveys, 209 (13.1%) participated in at least one CDC intervention component. After propensity score matching, 195 pairs were analyzed. No significant interaction effect was observed for SWB (β = 0.08, 95% confidence interval [CI]: −0.20, 0.37; p = 0.565). However, a significant interaction effect favored the intervention group for Internet usage frequency (odds ratio = 1.53, 95% CI: 1.08, 2.16; p = 0.016). A significant borderline interaction was also observed in health literacy (β = 0.13, 95% CI: −0.00, 0.26; p = 0.056), which reached significance in covariate-adjusted sensitivity analysis (p = 0.044). Subgroup analyses revealed that community hub participants showed significant interaction effects in health literacy (p = 0.021) and a trend toward reduced depressive symptoms (p = 0.084). Conclusions: The CDC intervention did not improve SWB over 2 years but enhanced Internet use and supported health literacy and depressive symptoms, particularly among hub participants. Community-based, multi-component interventions that integrate online and in-person activities may foster digital inclusion and specific health behaviors. Although SWB did not change in this study, these proximal gains may serve as foundational steps for long-term improvement. The study protocol was preregistered in the UMIN Clinical Trials Registry (UMIN000051393; Registered on 21 June 2023).

The association between patterns of internet use for older adults’ well-being is unclear. We examined the association between the frequency and purpose of internet use and subjective well-being in older Japanese adults. We analyzed cross-sectional data from 2343 community-dwelling older adults (aged 65–84 years). Subjective well-being was measured using the World Health Organization Well-Being Index as a continuous score, and internet use was categorized by frequency and purpose. Hierarchical linear regression analysis was controlled for sociodemographic and health-related covariates. After full adjustment, only daily (B = 1.04, 95% CI [0.53, 1.56]) and dual-purpose use (i.e., for both practical and social communication purposes; B = 0.80, 95% CI [0.28, 1.31]) were independently associated with higher well-being. The analysis of the combined patterns further suggested that daily use was the primary factor. For older adults, regularity of internet use was more strongly associated with well-being than diversity of purpose. Daily integration appears to be a key factor for realizing benefits, suggesting that sustained practice is the foundational step in building the digital capital necessary for a flourishing later life. Longitudinal studies are needed to confirm these findings and untangle the causal relationship between sustained internet use and improved well-being among older adults.

Promoting subjective well-being is a crucial challenge in aging societies. In 2022, we launched a community-based intervention trial (the Chofu-Digital-Choju Movement). This initiative centered on fostering in-person and online social connections to enhance the subjective well-being of older adults. This paper describes the study design and baseline survey. This quasi-experimental study involved community-dwelling older adults aged 65–84 years in Chofu City, Tokyo, Japan. A self-administered questionnaire was distributed to 3742 residents (1681 men and 2061 women), and a baseline survey was conducted in January 2022. We assessed subjective well-being (primary outcome); psychosocial, physical, and dietary factors; and the use of information and communication technology variables (secondary outcomes) among the participants. After the intervention involving online classes, community hubs, and community events, a 2-year follow-up survey will be conducted to evaluate the effects of the intervention, comparing the intervention group (participants) with the control group (non-participants). We received 2503 questionnaires (66.9% response rate); of these, the analysis included 2343 questionnaires (62.6% valid response rate; mean age, 74.4 (standard deviation, 5.4) years; 43.7% male). The mean subjective well-being score was 7.2 (standard deviation, 1.9). This study will contribute to the development of a prototype subjective well-being strategy for older adults.
