Diagnostic Significance of Absence of Post-Feeding Contraction of the Gallbladder in Biliary Atresia: Two Case Reports.

Ultrasonography is an essential part of the diagnostic process of biliary atresia (BA). The characteristic findings of BA include a hilar hyperechoic zone, the triangular cord sign (TCS), an absence of gallbladder contraction after feeding, and gallbladder atrophy. However, approximately 10% of patients with BA have a normal gallbladder. We herein present two cases of BA with normal morphology of the gallbladder as shown by ultrasonography. In the first case, the patient was positive for the TCS, negative for gallbladder atrophy, and positive for contraction of the gallbladder after feeding; the final diagnosis was hilar obstructive BA complicated by pancreaticobiliary maljunction. In the second case, the patient was positive for the TCS, negative for gallbladder atrophy, and negative for contraction of the gallbladder after feeding; the patient also had common bile duct obstruction and stenosis of the hepatic duct in the hilar region. Based on these two cases, we conclude that gallbladder findings are not diagnostic for BA because in some types, the gallbladder may be normal in morphology and even have the capacity for contraction after feeding.

The academic impact and value of an international online surgery lecture series.

Due to the worldwide travel restrictions caused by the 2019 coronavirus disease pandemic, many universities and students lost opportunities to engage in international exchange over the past 2 years. Teleconferencing systems have thus been developed to compensate for severe travel restrictions. Kansai Medical University in Japan and Vilnius University in Lithuania have a collaborative research and academic relationship. The two universities have been conducting an online joint international surgery lecture series for the medical students of both universities. Fifteen lectures were given from October 2021 to May 2022. The lectures focused on gastrointestinal surgery, gastroenterology, radiology, pathology, genetics, laboratory medicine, and organ transplantation. A survey of the attendees indicated that they were generally interested in the content and satisfied with attending this lecture series. Our efforts were successful in providing Japanese and Lithuanian medical students with the opportunity to engage in international exchange through lectures held in each other's countries.

Identity conflicts of student affairs officers in a medical university.

INTRODUCTION: Collaboration between student affairs officers and the faculty is important in dealing with the recent rapid changes in medical education, and mutual understanding is essential to ensure that participants become a cohesive social group. This study explores the identity conflicts of student affairs officers in medical universities using the figured worlds theory. METHODS: An exploratory qualitative case study was conducted with 24 student affairs officers at a private medical university in Japan. Data were collected through face-to-face, semi-structured interviews and analysed using thematic analysis from the perspective of a social constructivism paradigm. RESULTS: Qualitative analysis revealed the following three themes regarding the identity conflicts of student affairs officers: differences in the perception of medical students, difficulties in building trusting relationships with the faculty, and resistance to the medical university's traditional atmosphere. Student affairs officers tended to provide support from a student-centred perspective when interacting with medical students, while the faculty employed a teacher-centred perspective. DISCUSSION: To promote understanding between professions, it is necessary to set aside certain professional views and welcome dialogue with other professionals with different values, while also understanding the multi-layered context of medical education, so that conflicts can be handled optimally and relationships can be professionalised for social cohesion.

Inter-rater reliability of streetscape audits using online observations: Microscale Audit of Pedestrian Streetscapes (MAPS) global in Japan.

This study aimed to evaluate the inter-rater reliability of streetscape audits among online observations using the Microscale Audit of Pedestrian Streetscapes-Global version (MAPS-Global) in Japan. MAPS-Global observations were conducted on routes with distances ranging from 400 to 725 m from a residence toward a non-residential destination. Google Street View audits were independently conducted by two trained raters on each route. A tiered scoring system was applied to summarize the items at multiple levels of aggregation. Positive and negative valence scores were created based on the expected association with physical activity. Inter-rater reliability analyses were performed using kappa statistics or intraclass correlation coefficients (ICC). Of the 32 older adults participating in an intervention study in the community-wide physical activity promotion project in Fujisawa City, 19 addresses were used, excluding those with nearby addresses. Results demonstrated "excellent" agreement for most of the summary scores analyzed (kappa or ICC values of 0.75 or higher [80.4 %]), while 6.5 % of items exhibited "good" agreement (ICC = 0.60-0.74). By contrast, only 13.0 % of the scales had ICC values lower than 0.60 ("fair" or "poor" reliability). The results illustrated high reliability for the grand summary scores and composite subscale measures. However, caution should be exercised when interpreting subscale scores for less frequently observed negative attributes and aesthetic/social characteristics. The results presented in this study support the application of online observations using MAPS-Global in urban areas of Japan, which could be implemented to inform decisions related not only to physical activity but also to traffic safety.

Translation and cultural adaptation of the Japanese version of the interprofessional facilitation scale.

Effective interaction in interprofessional collaboration requires skills in interprofessional facilitation. The need for interprofessional learning and practice in Japan is highlighted by Japan's status as one of the most rapidly aging societies because good care for elderly people with complex needs requires effective collaboration between different professional groups. The development of interprofessional facilitation skills (including management of the additional complexities) among learners or professionals enhances interprofessional learning and consensus building and empowers them to make appropriate commitments when faced with difficult challenges. The 18-item interprofessional facilitation scale (IPFS) can be used to enhance interprofessional facilitation skills. Here, we aimed to develop a Japanese adapted version of the IPFS and to validate it for use with Japanese healthcare professionals. Consistent with guidelines for cross-cultural adaptation, three translators translated the original IPFS from English into Japanese, and an expert and all authors confirmed its face and content validity. The translated items were amended during backtranslation and expert reviews. Exploratory factor analysis was performed with 167 healthcare professionals to explore the underlying structure of the items. This analysis revealed two factors with good internal consistency (Cronbach's alpha > 0.8), which were labelled as: (1) encouraging interprofessional interaction and (2) respect for each professional. The original factor 'Encouraging interprofessional interaction' was divided into two factors in the study. One reason for this division might be related to the behaviour of Japanese health professionals, that is, most Japanese might understand that 'facilitation' encourages relationships as contextual belonging that are distinct from relationships based on respect for others. This mindset is likely based on the notion of 'relationalism', which is fundamental in Japanese culture. Further investigation of this Japanese version of the IPFS will strengthen factor construction and improve scrutiny of the relationships between factors.

Social jetlag affects subjective daytime sleepiness in school-aged children and adolescents: A study using the Japanese version of the Pediatric Daytime Sleepiness Scale (PDSS-J).

The aim of this study was to elucidate the level of daytime sleepiness in Japanese school-aged children and adolescents, and to examine associated factors including sleep loss and social jetlag using the Japanese version of the Pediatric Daytime Sleepiness Scale (PDSS-J). After the linguistic validation of the PDSS-J with a multi-step translation methodology, consisting of forward translation, back translation, expert review and cognitive debriefing interviews, we conducted a psychometric validation for 492 students aged 11-16 years (46.7% boys) of public elementary school, junior high school and high school, using the PDSS-J, the Karolinska Sleepiness Scale (KSS), and bedtimes and wake-up times on school days and free days. Internal consistency (Cronbach's alpha) of the PDSS-J was 0.77, and the test-retest reliability demonstrated by the intraclass coefficient was 0.88. Multivariate logistic regression analysis revealed that both short sleep duration and social jetlag were identified as factors associated with daytime sleepiness, after adjustment for age and sex. PDSS-J scores were significantly higher in the group with large social jetlag with or without sufficient sleep duration than in the group with sufficient sleep duration and small social jetlag. The PDSS-J is an important tool for assessing daytime sleepiness, given its ease of administration and robust psychometric properties. The impact of not only sleep loss but also social jetlag on daytime sleepiness among school-aged children and adolescents must be fully taken into account.

Validation of the Mongolian version of the SF-36v2 questionnaire for health status assessment of Mongolian adults.

BACKGROUND: Ulaanbaatar, Mongolia, is one of the world's worst air-polluted cities, but effects of this air pollution on the population health status have not yet been evaluated. Therefore, we developed a Mongolian version of the SF-36v2 questionnaire to investigate the health status of Mongolian population. METHODS: Health checkups were conducted in Ulaanbaatar and the health status was measured using a Mongolian translated version of the SF-36v2 questionnaire. The reliability and validity of the Mongolian SF-36v2 questionnaire, and the relationship between health status and respiratory condition were examined. RESULTS: Factor analysis of the Mongolian SF-36v2 questionnaire showed that the "Role-physical" and "Role-emotional" were classified into a single subscale. The "Mental health" and "Vitality" were each divided into two subscales. Cronbach's alpha and intraclass correlation coefficient (ICC) for reproducibility were >0.7, except for "General health perceptions" (Cronbach's alpha and ICC < 0.7), "Social functioning" (Cronbach's alpha < 0.7), and "Vitality" (ICC < 0.7). The SF-36v2 subscales and the corresponding items of the COOP/WONCA charts were correlated, and subjects with respiratory symptoms showed lower SF-36v2 scores compared to normal subjects, suggesting external validity. Subjects with respiratory symptoms showed significantly lower scores for the majority of the SF-36v2 subscales than those with normal lung function. In subjects with combined ventilatory impairment, "Physical functioning", "Role-physical", "Bodily pain", and "Vitality" scores were significantly lower than those with normal lung function. CONCLUSIONS: The Mongolian version of the SF-36v2 questionnaire provides substantial reliability and validity, and is useful for evaluating the health status of Mongolian adults with ventilatory impairment. Health status measured by SF-36v2 was significantly aggravated by combined ventilatory impairment when compared with normal lung function.

How do case presentation teaching methods affect learning outcomes?--SNAPPS and the One-Minute preceptor.

BACKGROUND: Various techniques have been developed to enable preceptors to teach residents effectively in outpatient settings to promote active learning, including SNAPPS and the One-Minute Preceptor (OMP). This study aimed to ascertain the differences between SNAPPS and the OMP in case presentation content and learner evaluation when used to teach residents about case presentation. METHODS: From 2011 to 2013, participants were 71 junior clinical residents employed in two hospitals for clinical training. They were randomly allocated to two groups, one using SNAPPS and the other the OMP. From recorded discussions, the "differential diagnoses", "questions and uncertainties", "treatment plans", and "learning issues" were counted. Also, a self-evaluation form was distributed at the end of the study to evaluate the residents' satisfaction with the case presentation. RESULTS: Members of the SNAPPS group used significantly more meaning units related to questions and uncertainties compared with those of the OMP group (P < 0.001). Self-evaluation sheets revealed that members of the SNAPPS group had significantly higher positive responses than those of the OMP group in terms of the following evaluations: "It was easy to bring up questions and uncertainties" (P = 0.046), "It was easy to present the case efficiently" (P = 0.002), "It was easy to present the case in the sequence given" (P = 0.029), and "I was able to give an in-depth case presentation" (P = 0.005). CONCLUSIONS: SNAPPS may induce more meaning units related to questions and uncertainties and give more satisfaction to residents than the OMP.

Japanese version of the Munich Parasomnia Screening: translation and linguistic validation of a screening instrument for parasomnias and nocturnal behaviors.

OBJECTIVE: There is no broad screening instrument that can comprehensively assess parasomnias and sleep-related movement disorders listed in the International Classification of Sleep Disorders. The aim of this study was to develop the Japanese version of the Munich Parasomnia Screening (MUPS), a screening instrument for parasomnias and nocturnal behaviors, which was developed and validated at the Max Planck Institute of Psychiatry. METHODS: A multi-step translation methodology consisting of forward translation, back translation, expert review, and cognitive debriefing interviews was performed between June and November 2011. RESULTS: The English version of the MUPS was translated into Japanese, and the original author performed an expert review on the basis of a detailed report on the forward and back translation steps. The cognitive debriefing was carried out in five patients with parasomnia. The mean time to fill out the questionnaire was 8 minutes (ranging from 2 to 17 minutes). The authors reviewed and discussed the results of the cognitive debriefing interviews and modified the Japanese version. The final Japanese version was confirmed to be conceptually equivalent to the original English version. CONCLUSION: The Japanese version of the MUPS is an easy-to-use self-rating instrument for parasomnia and nocturnal behavior screening, consistent with the original version. The usage of this instrument would enable clinicians to quickly screen the past history and current frequency of nocturnal behaviors.

Development of a novel, short, self-completed questionnaire on empowerment for patients with type 2 diabetes mellitus and an analysis of factors affecting patient empowerment.

BACKGROUND: Patient empowerment has recently been proposed as an important concept in self-management for effective glycemic control. A concise self-completed questionnaire for patients with type 2 diabetes mellitus was created to comprehensively evaluate their empowerment on the basis of self-managed dietary/exercise behaviors, psychological impact, and family support. The reliability and validity of this short questionnaire were tested and factors relating to patient empowerment were analyzed. METHODS: The self-completed empowerment questionnaire was based on questionnaires for self-managed dietary and exercise behaviors, the Appraisal of Diabetes Scale, and the Diabetes Family Behavior Checklist. The questionnaire was trialed on 338 male and female patients with type 2 diabetes mellitus who lived with family. The validity and reliability of the questionnaire were investigated and stepwise multiple linear regression analysis was used to identify factors that affect patient empowerment. RESULTS: The self-completed patient empowerment questionnaire included 13 questions on background data (e.g., age, gender, and HbA1c) and 18 questions within five scales to assess self-managed dietary behaviors, self-managed exercise behaviors, and psychological impact of diabetes, as well as positive and negative feedback in patient-family communication. The questionnaire showed sufficient internal consistency, construct validity, reproducibility, factorial construct validity, and concurrent validity. The results were generally satisfactory, and the questionnaire reflected the particular characteristics of treatment methods. Multiple linear regression analysis showed that patient empowerment was strongly affected by the number of disease-related symptoms, age, and gender. CONCLUSIONS: The results suggest that the concise self-completed empowerment questionnaire developed here is useful for measuring the empowerment of individual patients and evaluating the impact of symptoms and therapies on empowerment.

Validity of direct ophthalmoscopy skill evaluation with ocular fundus examination simulators.

OBJECTIVE: We examined how direct ophthalmoscopy (DO) skills can be evaluated in a clinical setting using a simulator, and determined the appropriate assessment criteria for the DO skills in practical tests such as the Objective Structured Clinical Examination (OSCE). DESIGN: Cross-sectional study. PARTICIPANTS: Medical students, residents, and attending physicians (73 total participants). METHODS: We selected the following 3 factors that may indicate the ability to perform nonmydriatic direct funduscopy: (i) experience: total number of cases examined (without mydriasis); (ii) frequency: number of cases examined during the previous month; and (iii) range: viewable fundus field range. We used a fundus simulator with 3-level adjustable pupil sizes (2, 3.5, and 5 mm) and created original test slides for use in the simulator. We counted the number of correct answers of each participant for each pupil size using the simulator and test slides. RESULTS: There were significant differences in the median number of correct answers for pupil diameters of 2 (p = 0.008) and 3.5 mm (p = 0.007) among groups divided according to the total number of cases examined (without mydriasis). There were no significant differences among groups divided according to the viewable fundus field range (2 mm: p = 0.103, 3.5 mm: p = 0.083, 5 mm: p = 0.347). CONCLUSIONS: The results suggest a possible relation between the surrogate indicators "experience" and "range" and DO skills using a fundus simulator. The surrogate indicator experience showed a strong relation to DO skills using a fundus simulator.

The reliability and validity of the Japanese version of the Diabetes Family Behavior Checklist (DFBC) for assessing the relationship between type 2 diabetes mellitus patients and their families with respect to adherence to treatment regimen.

AIMS: An appropriate questionnaire for assessing family support of self-management behavior of Japanese Type 2 diabetes patients has yet to be developed. We produced a Japanese version of the Diabetes Family Behavior Checklist (DFBC) and tested its reliability and validity. METHODS: The study enrolled Japanese patients with Type 2 diabetes mellitus who were living with their families: 158 patients in the Insulin Group and 169 in the Oral Hypoglycemic Agents Group. The external validity of the DFBC was tested with questionnaires of self-managed dietary and exercise behaviors, the Appraisal of Diabetes Scale (ADS), and HbA1c. RESULTS: The DFBC comprised two components: "Negative" and "Positive" feedbacks. Cronbach's alpha in the subcategories was ≥0.93, and the test-retest showed an intraclass correlation coefficient of 0.89. "Positive" and "Negative" scores correlated with self-managed dietary and/or exercise behaviors, the ADS scores in the both Groups. For patients having HbA1c levels of ≤6.8% there was a correlation between their "Positive" and "Negative" scores and the scores of their families in both Groups. CONCLUSION: The DFBC showed evidence of validity and reliability and may be a useful tool for quick assessment of self-managed treatment behavior of Japanese Type 2 diabetes patients and support received from their family.

The reliability and validity of the Japanese version of the Appraisal of Diabetes Scale for type 2 diabetes patients.

AIMS: An appropriate questionnaire for measurement of the psychological burden of self-management or behavior modification in type-2 diabetes patients has yet to be developed in Japan. This study was conducted to test the reliability and validity of the Japanese version of the Appraisal of Diabetes Scale (ADS). METHODS: the study enrolled 346 Japanese patients with type 2 diabetes: 200 men and 146 women who were 63.2 ± 10.1 and 62.2 ± 11.9 years of age and had HbA1c levels of 6.9 ± 1.2% and 7.3 ± 1.9%, respectively. RESULTS: the questionnaire was divided into three components: "Psychological impact of diabetes", "Sense of self-control", and "Efforts for symptom management". Cronbach's alpha was 0.746-0.628. Significant correlations were observed between "Sense of self-control" and self-managed dietary and exercise behaviors and HbA1c levels; between "Psychological impact of diabetes" and various treatments, symptoms causing anxiety, and HbA1c levels; and between "Efforts for symptom management" and dietary and nutritional behaviors. The questionnaire showed better evidence of internal consistency, test-retest reliability and validity. CONCLUSION: our results suggested that the Japanese version of ADS may be a useful tool for the quick assessment of common anxieties and motivation toward treatment in patients with type 2 diabetes.
