Background/Aims:
Although endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is performed globally, the procedure remains challenging. Guidewire manipulation is the most difficult step, and there are few reports on the factors associated with unsuccessful guidewire manipulation. This study aimed to assess the significance of the puncture angle on EUS images and identify the most effective guidewire rescue method for patients with unsuccessful guidewire manipulation.
Methods:
We retrospectively enrolled 115 patients who underwent EUS-HGS between May 2016 and April 2022 at two centers. The puncture angle between the needle and the intrahepatic bile duct was measured through EUS movie records.
Results:
Guidewire manipulation was unsuccessful in 28 patients. Receiver operating characteristic (ROC) curves identified an optimal puncture angle cutoff value of 85° (cutoff value, 85°; area under the ROC curve, 0.826; sensitivity, 85.7%; specificity, 81.6%). Multivariate analysis demonstrated that a puncture angle <85° was a significant risk factor for unsuccessful guidewire manipulation (odds ratio, 19.8; 95% confidence interval, 6.42–61.5; p<0.001). Among the 28 unsuccessful cases, 24 patients (85.7%) achieved successful guidewire manipulation using various rescue methods.
Conclusions
The puncture angle observed on EUS is crucial for guidewire manipulation. A puncture angle of <85° was associated with unsuccessful guidewire manipulation.

Journal of Gastric Cancer 2023;23(4):609-621
Purpose:
Determination of optimal treatment strategies for HER2-positive advanced gastric cancer (AGC) in randomized trials is necessary despite difficulties in direct comparison between trastuzumab deruxtecan (T-DXd) and nivolumab as third or later-line treatments.
Materials and Methods:
This single-institution, retrospective study aimed to describe the real-world efficacy and safety of T-DXd and nivolumab as ≥ third line treatments for HER2-positive AGC between March 2016 and May 2022. Overall, 58 patients (median age, 64 years;69% male) were eligible for the study (T-DXd group, n=20; nivolumab group, n=38).
Results:
Most patients exhibited a HER2 3+ status (72%) and presented metastatic disease at diagnosis (66%). The response rates of 41 patients with measurable lesions in the T-DXd and nivolumab groups were 50% and 15%, respectively. The T-DXd and nivolumab groups had a median progression-free survival of 4.8 months (95% confidence interval [CI], 3.3, 7.0) and 2.3 months (95% CI, 1.5, 3.5), median overall survival (OS) of 10.8 months (95% CI, 6.9, 23.8) and 11.7 months (95% CI, 7.6, 17.1), and grade 3 or greater adverse event rates of 50% and 2%, respectively. Overall, 64% patients received subsequent treatment. Among 23 patients who received both regimens, the T-DXd–nivolumab and nivolumab–T-DXd groups had a median OS of 14.0 months (95% CI, 5.0, not reached) and 19.3 months (95% CI, 9.5, 25.1), respectively.
Conclusions
T-DXd and nivolumab showed distinct efficacy and toxicity profiles as ≥ third line treatments for HER2-positive AGC. Considering the distinct features of each regimen, they may help clinicians personalize optimal treatment approaches for these patients.

Objective:
The objective of this study was to examine the current trends in fertility-sparing (FS) treatment for young atypical endometrial hyperplasia (AEH) and endometrial cancer (EC) patients in Japan.
Methods:
This study was conducted by the Committee on Gynecologic Oncology of the Japan Society of Obstetrics and Gynecology (JSOG) in the 2017–2018 fiscal year. A nationwide, retrospective questionnaire-style survey—as performed. We collected the data of 413 patients from 102 JSOG gynecological cancer registered institutions.
Results:
FS treatment was performed with medroxyprogesterone (MPA) (87.2%) or MPA + metformin (11.6%). Pathological complete remission (CR) after initial treatment was achieved in 78.2% of patients. The significant clinicopathological factors correlated to CR after initial treatment were histology (AEH vs. endometrioid carcinoma grade 1 [ECG1]), body mass index (BMI) (<25 vs. ≥25 kg/m2), and treatment period (<6 vs. ≥6 months). ECG1, time to complete remission (TTCR) ≥6 months, maintenance therapy (−), and pregnancy (−) were associated with a significantly higher risk of recurrence on multivariate analysis. The total pregnancy rate was 47%, and the live birth rate was 40.1%. Patients who received infertility treatments showed a higher live birth rate (50.6%) than those who did not (7.7%).
Conclusion
In this survey, we confirmed that FS treatment in Japan is centered on MPA alone and in combination with metformin, and that the treatment efficacy is similar to that reported in previous reports. A multicenter survey study in Japan showed FS treatment for young AEH and EC patients in compliance with the indications is feasible.

Total pelvic exenteration (TPE) is sometimes required for radical treatment of locally advanced or recurrent gynecologic cancer [1]. However, TPE with a transabdominal approach requires highly advanced techniques in the case of repeated surgery due to the effects of primary surgery and/or chemoradiotherapy, especially when a transabdominal approach is used. Recent technical advances in transanal/transperineal endoscopic surgery have proved beneficial for complicated surgery in the deep pelvis [2]. Here we introduce our surgical procedure for combined laparoscopic and transperineal endoscopic TPE (TpTPE) for pelvic recurrence of cervical cancer. A 42-year-old woman was diagnosed with vaginal stump recurrence of cervical cancer involving the rectum, bladder, and ureters following hysterectomy and pelvic lymph node dissection as primary surgery and chemotherapy/chemoradiotherapy for previous recurrences. We decided to perform TpTPE with a combined laparoscopic approach. The GelPOINT advanced access platform was fixed through a perineal skin incision around the tightly closed anus, external urethral orifice, and vagina. With sufficient pneumopelvic pressure (12 mmHg), TpTPE was performed under a good surgical view without any effect of the primary surgery. A ureterostomy and sigmoid colostomy were created and a right gracilis muscle flap was used to reconstruct the pelvic defect. The total operative time and estimated blood loss were 887 minutes and 497 mL, respectively. Histopathological examination revealed recurrent cervical cancer invading the rectum, bladder, and bilateral ureters with negative surgical margins. The postoperative course was uneventful except for paralytic ileus. The patient was discharged on postoperative day 18. TpTPE is a technically feasible and effective approach for locally advanced pelvic tumors.

This study aimed to examine characteristics of physical functions, physical activity, and cognitive functions among community-dwelling older people who stopped driving automobiles. Participants were 589 community-dwelling older people (age: 65–89, 71.4 ± 5.1 years; 403 men, 186 women). The participants underwent nine physical assessments—hand grip strength, knee extension strength, timed up-and-go test, chair stand, one leg standing with open eyes, functional reach, vertical jump, preferred gait speed, maximal gait speed—and were evaluated for physical activity; and five cognitive assessments—the Mini-Mental State Examination (MMSE), Logical Memory I and II (WMS-R LM-I, LM-II) subtests of the Wechsler Memory Scale-Revised; and Trail Making Test A and B (TMT-A, TMT-B). They were divided into current driver (379 men, 169 women) and driving cessation (24 men, 17 women) groups. Among men, the driving cessation group had poorer vertical jump, TMT-A, and TMT-B results, while women had poorer hand grip strength, one leg standing with open eyes, WMS-R LM-II, and LM-II results, and longer inactivity time, compared with the current driver group and adjusted for covariates (P < 0.05 for all). The findings suggest driving cessation among community-dwelling older people is significantly associated with poorer physical functions, physical activity, and cognitive functions compared with those in current drivers.

Medical Education 2020;51(2):109-121
Introduction・Purpose: We conducted qualitative research to explore the psychosocial processes by which dental trainees overcome difficulties during clinical training. Our focus was on their resilience. Methods: Semi-structured interviews with nine trainee dentists were conducted. For the data analysis, we used Modified Grounded Theory Approach. Results: The three factors, namely, “relationships with others” , “inner strengths” , and “acting autonomously” , contributed to the processes by which negative effects of trainee dentists changed into positive ones. Discussion: It was suggested that these factors could provide clues to understanding the psychological burden of dental trainees and how to support them in gaining self-confidence.

BACKGROUND:
The gender-specific characteristics of individuals at an increased risk of developing depression currently remain unclear despite a higher prevalence of depression in women than in men. This study clarified socioeconomic and lifestyle factors associated with an increased risk of subclinical depression in general Japanese men and women.
METHODS:
Study participants were residents not receiving psychiatric treatments in 300 sites throughout Japan in 2010 (1152 men, 1529 women). Multivariable-adjusted odds ratios (OR) and 95% confidence intervals (95%CIs) for socioeconomic factors and lifestyle factors were calculated using a logistic regression analysis.
RESULTS:
Risk of depressive tendencies was significantly higher in men who were single and living alone (OR, 3.27; 95% CI, 1.56-6.88) than those married. The risk was significantly lower in women who were not working and aged ≥ 60 years (OR, 0.39; 95% CI, 0.22-0.68) and higher in men who were not working and aged < 60 years (OR, 3.57; 95%CI, 1.31-9.72) compared with those who were working. Current smoking was also associated with a significantly increased risk of depressive tendencies in women (OR, 2.96; 95% CI, 1.68-5.22) but not in men.
CONCLUSIONS
Socioeconomic and lifestyle factors were associated with an increased risk of depressive tendencies in general Japanese. Related factors were different by sex.

BACKGROUND:
Oral health is thought to be associated with diet quality, and socioeconomic status (SES) affects both oral health and diet. The aim of this study was to investigate the association between the number of teeth and dietary intake as well as nutritional biomarker, considering the subjects' SES.
METHODS:
We conducted a cross-sectional analysis of data from 2049 individuals aged ≥ 50 years from the National Integrated Project for Prospective Observation of Non-communicable Disease and its Trends in the Aged 2010. The number of remaining teeth was categorized into age-specific quartiles (Q1 to Q4). We assessed the adjusted means and 95% confidence intervals for dietary variables by the number of teeth using analysis of covariance. Stratified analyses by SES were also conducted.
RESULTS:
The intake of grain products was 31 g higher, and those of vegetables and meat were 30 g and 8 g lower, respectively, in Q1 (fewer teeth) than in Q4 (more teeth). Carbohydrate intake was higher whereas protein, minerals (potassium, magnesium, and zinc), vitamins (vitamins A, E, B, B, β-carotene, and folic acid), and dietary fiber intakes were lower among individuals with fewer teeth. Adjusted mean serum albumin levels were low in Q1. The associations between the number of teeth and dietary intake were more evident in individuals with a low SES.
CONCLUSIONS
Having few remaining teeth was associated with a low nutrient intake and low serum albumin levels in middle-aged and older Japanese adults, and these associations were more evident in individuals with low SES.

BACKGROUND/AIMS: Decreased trough levels of infliximab (TLI) and antibodies to infliximab (ATI) are associated with loss of response (LOR) in Crohn's disease. Two prospective studies were conducted to determine whether TLI or ATI better correlates with LOR (Study 1), and whether TLI could become a predictor of mucosal healing (MH) (Study 2). METHODS: Study 1 was conducted in 108 patients, including those with LOR and remission to compare ATI and TLI in discriminating the 2 conditions based on receiver operating characteristic (ROC) curve analyses. Study 2 involved 35 patients who were evaluated endoscopically. RESULTS: In Study 1, there were no differences between the 2 assays in ROC curve analyses; the TLI cutoff value for LOR was 2.6 µg/mL (sensitivity, 70.9%; specificity, 79.2%), and the ATI cutoff value was 4.9 µg/mL (sensitivity, 65.5%; specificity, 67.9%). The AUROC (area under the ROC curve) of TLI was greater than that of ATI. AUROC was useful for discriminating between the 2 conditions. In Study 2, the TLI was significantly higher in the colonic MH group than in the non-MH group (2.7 µg/mL vs. 0.5 µg/mL, P=0.032). CONCLUSIONS: TLI is better than ATI for clinically diagnosing LOR, and a correlation was observed between TLI and colonic MH.

Medical Education 2018;49(1):23-33
Introduction: This study aims to explore the processes by which trainee dentists are able to autonomously engage in clinical practice.Methods: Semi-structured interviews with 16 trainee dentists were conducted. For the data analysis, Modified Grounded Theory Approach was employed in this study.Results: At the early stage of clinical education, trainees tended to passively receive and follow the supervisor's instruction. However, through their reiterative reflection on clinical experience and feedback from their supervisor, they gradually established a proper way of treating and caring for patients. They also understood their own abilities. Furthermore, they could obtain a holistic viewpoint of dental treatment. Their experiences led to active engagement with dental practice.Discussion: In order for the learners to be autonomously involved in their practice, educators need to provide scaffolding and support that encourage them to solve individual problems in the given context.
