Impact of value similarity on social trust in medical students: a cross-sectional web survey.

BACKGROUND: Social trust in medical students is trust in the cluster of medical students and not individual medical students. Social trust in medical students seems critical in clinical practice since citizens often face unknown medical students for the first time. However, most previous research has focused on interpersonal trust in particular medical professions, and social trust in medical students has not been addressed sufficiently. In social science, the Salient Value Similarity model has demonstrated that the value similarity between professionals and citizens is associated with social trust. This research aimed to explore the relationship between social trust in medical students and the perception of value similarity. This study also aimed to determine whether the information of medical students strengthens social trust in them. METHODS: We conducted a cross-sectional study to investigate how the perception of value similarity affects social trust. The participants answered the social trust questionnaires before and after reading a brief summary of the medical education curriculum and certification via the internet in Japan. The model structure of social trust in medical students, including the perception of value similarity, was investigated using SEM. A paired t-test was used to examine the effect of informing citizens about the knowledge, skills, and professionalism requirements of students attending medical school on social trust by reading the brief summary. RESULTS: The study included 658 participants, who all answered a web questionnaire. Social trust in medical students was associated with the perception of ability and value similarity. Social trust in medical students, the perception of ability, and value similarity were improved by information about medical students. CONCLUSIONS: The perception of ability and value similarity seem to affect social trust in medical students. Information on medical education regarding the knowledge, skills, and professionalism of medical students may improve social trust in these students. Further research is required to sophisticate the model of social trust in medical students by exploring social trust in the medical students' supervisors in clinical settings.

Anterior versus posterior radical antegrade modular pancreatosplenectomy for pancreatic body and tail cancer: an inverse probability of treatment weighting with survival analysis.

PURPOSE: Radical antegrade modular pancreatosplenectomy (RAMPS) is a standard procedure for patients with pancreatic body and tail cancer. There are two types of RAMPS: anterior and posterior, but their indications and surgical outcomes remain unclear. We compared the surgical outcomes, postoperative course, and prognosis between anterior and posterior RAMPS. METHODS: Between 2007 and 2020, 105 consecutive patients who underwent RAMPS for pancreatic body and tail cancers were divided into an anterior RAMPS group (n = 30) and a posterior RAMPS group (n = 75). To adjust for differences in preoperative characteristics and intraoperative procedures, an inverse probability of treatment weighting (IPTW) analysis was done, using propensity scores. RESULTS: After IPTW adjustment, the postoperative body temperature of the posterior RAMPS group and the amount of drain discharge in the anterior RAMPS group were significantly lower, from postoperative days (PODs) 1 to 3, but there were no differences in postoperative complications, recurrence patterns, or prognosis between the two groups. Regarding the diagnostic ability of multidetector-row computed tomography (MD-CT) for direct tumor involvement of the left adrenal gland, the sensitivity and specificity were 100% and 90.0%, respectively. CONCLUSION: Pancreatic body and tail cancer without apparent preoperative direct tumor involvement of the left adrenal gland on MD-CT may be sufficient indication for anterior RAMPS.

Effectiveness of individual nutrition counselling for the prevention of undernutrition among elderly people living in depopulated areas: secondary analysis of a model project in Tsu city.

Objectives: To examine the effectiveness of nutrition counselling (NC) in preventing undernutrition in elderly people living in depopulated areas. Design: Participants were elderly people aged at least 65 years living in a depopulated area. Participants completed self-administered questionnaires evaluating nutritional status, frailty and body composition at the start of the study, after a non-NC period (3-month control) and after an NC period (3-month intervention). During the NC period, participants attended monthly 1-hour NC sessions over 3 months. Sessions were conducted in three areas (A, B and C), and the schedule was staggered so that the NC period in one area was conducted simultaneously with the non-NC period of the next. All sessions within an area were attended by the same registered dietitian. Outcomes were assessed three times: before the non-NC period, after the non-NC period and after the NC period. The effects of NC were assessed by comparing the results between the non-NC and NC periods of all participants, using the Cochran-Mantel-Haenszel stratified test. Outcome measures: The primary outcome was undernutrition, as determined by the Mini Nutritional Assessment-Short Form. Secondary outcomes were Dietary Diversity Score (DVS), body weight and frailty. Body composition was also assessed. Results: Of 106 individuals who joined the project, 61 completed the project and were analysed. The NC in this study had no effect on the primary outcome. DVS in area A was significantly higher after the NC period than after the non-NC period (p=0.012). Frailty in area C was significantly lower after the NC period than after the non-NC period (p=0.025). NC had no significant effects on the other outcomes. Conclusions: NC improved food variety but did not improve nutritional status, frailty or body composition.

DUV coherent light emission from ultracompact microcavity wavelength conversion device.

A unique design of our ultracompact microcavity wavelength conversion device exploits the simple principle that the wavelength conversion efficiency is proportional to the square of the electric field amplitude of enhanced pump light in the microcavity, and expands the range of suitable device materials to include crystals that do not exhibit birefringence or ferroelectricity. Here, as a first step toward practical applications of all-solid-state ultracompact deep-ultraviolet coherent light sources, we adopted a low-birefringence paraelectric SrB4O7 crystal with great potential for wavelength conversion and high transparency down to 130 nm as our device material, and demonstrated 234 nm deep-ultraviolet coherent light generation, whose wavelength band is expected to be used for on-demand disinfection tools that can irradiate the human body.

Improved Q-factors of III-nitride-based photonic crystal nanocavities by optical loss engineering.

III-nitride-based two-dimensional photonic crystal (2D-PhC) cavities with high-quality factors (Q-factors) have a large potential application, however realized Q-factors in the visible wavelength regime have been relatively moderate. In this study, we demonstrate the design and fabrication of 2D-PhC cavities to achieve high Q-factors, especially in the visible range. From the comparison of numerical calculations and the experimental results, we discuss the dominant optical losses that limit the Q-factor of H3-type cavities formed in an Eu,O-codoped GaN film. Based on these results we designed 2D-PhC cavities which can effectively suppress these dominant losses. We fabricated 2D-heterostructures and show a high Q-factor of 10500 at a resonant wavelength of ∼660 nm, which is considerably larger than any existing GaN-based nano/micro-resonators in the visible region. This study provides design guidelines for the realization of high Q-factors in photonic crystal nanocavities based on III-nitride semiconductors.

Relationship between medical students' career priority and specialty choice: A nationwide multicenter survey.

BACKGROUND: The shortage of physicians in several specialties has been brought to public attention in several countries. However, little is known about factors affecting medical students' specialty choice. The objectives of our study were to illustrate medical students' career priority clusters and to assess their association with specialty preference. METHODS: We conducted a nationwide multicenter survey in 2015 at 17 medical schools. The study participants were asked their top three specialty preferences, demographic characteristics, and 14 career priority questions. Multilevel logistic regression models were used to determine the effect of each variable on student career choice. RESULTS: A total of 1264 responses were included in the analyses. The top five specialty choices were internal medicine: 833, general practice: 408, pediatrics: 372, surgery: 344, and emergency medicine: 244. An exploratory factor analysis mapped the 14 career priorities into 3-factor solution: "primary care orientation," "advanced and specific care," and "personal life orientation." Multilevel logistic regression models yielded satisfactory accuracy with the highest ROC curve (AUROC) noted in surgery (0.818), general practice (0.769), and emergency medicine (0.744). The career priorities under "primary care orientation" had positive association with choosing general practice, emergency medicine, internal medicine, and pediatrics. The "advanced and specific care" career priorities facilitated surgery and emergency medicine choice, while reducing the likelihood of choosing less procedure-oriented specialties, such as internal medicine, general practice, and pediatrics. CONCLUSIONS: Our results demonstrated medical students' career priorities and their association with specialty preference. Individualized career support may be beneficial for both medical students and each specialty fields.

The "Healthy Akame!" community - government - university collaboration for health: a community-based participatory mixed-method approach to address health issue in rural Japan.

BACKGROUND: Although Japan has a decentralized public health system, local governments have considered expert opinions over those of the community in decisions about public health programs. Differences in communities' interests may create gaps between health program objectives and implementation. We hypothesized that community-based participatory research (CBPR), which involves the community at every step, promotes effective program implementation and community empowerment. This study addressed the first step of CBPR, assessing community needs and developing tailored health program for a rural community in Japan. METHODS: In this sequential exploratory mixed-method study (qualitative followed by quantitative), we first formed a community advisory board (CAB) representing community organizations, city officials, and university researchers. The CAB conducted group discussions with community residents to identify the community's health issues and strengths. These group discussions were analyzed using thematic analysis, and the results were used to develop a questionnaire, which was subsequently sent to all households in the community to obtain priority scores for health issues and proposed action and to assess willingness to participate in community health program. The CAB then designed a program using the overall study results. RESULTS: Ten group discussions with 68 participants identified the following health issues: 1) diseases; 2) unhealthy behaviors; and 3) unsupportive environment. Nature, vacant lots, and local farms were considered local strengths. Of a total of 1470 households in the community, questionnaires were collected from 773 households. Cancer, lifestyle-related diseases, and cerebrovascular diseases were ranked as the most important health problems. Improving services and access to medical checkups, use of public space for exercise, local farming, and collaboration with the community health office were considered necessary to address these health problems. Considering feasibility and the availability of resources in the community, the CAB decided to focus on lifestyle-related diseases and designed activities centered on health awareness, nutrition, and exercise. These activities drew on community's strengths and were adapted to Japanese culture. CONCLUSIONS: The community's priority health problem was closely related to the epidemiology of diseases. The CBPR approach was useful for identifying community's needs and for designing a unique community health program that made use of local strengths.

Clinical impact of perinephric fat stranding detected on computed tomography in patients with acute pyelonephritis: a retrospective observational study.

Perinephric fat stranding (PFS) is often detected on computed tomography (CT) in patients with acute pyelonephritis (APN). However, its clinical impact remains unclear. This study aimed to evaluate the clinical impact of PFS detected on CT in patients with APN. This retrospective observational study included patients with APN who underwent CT (median age, 79.5 years). Patients were classified into PFS (patients with PFS observed on CT) and non-PFS (patients without PFS observed on CT) groups, which were further classified into bacteraemia and non-bacteraemia groups. Clinical findings between the groups were compared. Among 194 patients who underwent CT, 111 (57.2%) patients demonstrated PFS. The rate of bacteraemia was significantly higher in the PFS group than in the non-PFS group (55.2 vs. 23.1%, p < 0.001). CT findings other than PFS were not associated with bacteraemia. The median peak body temperature was significantly higher in the PFS group than in the non-PFS group (38.8 vs. 38.5 °C, p < 0.001); however, the duration of fever and in-hospital mortality rates were not significantly different between the groups. Concordance between blood and urine culture results was observed in 75.0% of the patients; the presence of PFS was not different between patients with concordant and discordant results, regardless of the pre-treatment antibiotic used. Our findings suggest that the presence of PFS in patients with APN predicts bacteraemia; thus, clinicians should consider obtaining blood cultures if PFS is found on CT in patients with APN, even if the patients had received antibiotics prior to admission.

Effectiveness of monthly and bimonthly follow-up of patients with well-controlled type 2 diabetes: a propensity score matched cohort study.

BACKGROUND: On average, patients in Japan with type 2 diabetes mellitus have a clinical consultation every month, although evidence for a favorable follow-up interval is lacking. This study investigated whether the follow-up interval can be extended by comparing the clinical outcomes and cost for monthly versus bimonthly follow-up of patients with well-controlled diabetes mellitus. METHODS: We combined administrative claims data from the National Health Insurance and the Health Checkups Program data of Tsu city, Japan between 2011 and 2014 to conduct a retrospective cohort study of patients with well-controlled type 2 diabetes mellitus. Propensity scores were used to assemble a matched-pairs cohort from patients who had monthly and bimonthly follow-up. Equivalence between two groups was assessed by designating the proportion of patients who maintained good control of their diabetes in the subsequent year as a primary outcome. The proportion achieving target blood pressure and lipid levels, favorable lifestyle, and annual cost were compared as secondary outcomes. RESULTS: Of 12,145 participants, 693 with monthly follow-up and 693 with bimonthly follow-up were matched using propensity scores. In the monthly follow-up group 654 (94.4%) remained under good diabetic control, versus 658 (95.0%) in the bimonthly group (difference: 0.6%; 95% confidence interval: - 1.8 to 2.9%). All secondary outcomes were equivalent for the monthly and bimonthly follow-up groups except the proportion achieving target blood pressure, the proportion engaging in regular exercise, and annual cost. CONCLUSIONS: For patients with well-controlled diabetes mellitus, although frequent follow-up by a physician does not affect the control of blood glucose level in the subsequent year, the annual treatment cost becomes much higher. We suggest that patients with well-controlled diabetes can be followed up less often.

Family Caregivers' Perspectives for the Effect of Social Support on their Care Burden and Quality of Life: A Mixed-Method Study in Rural and Sub-Urban Central Japan.

Japan has adopted community-based integrated long-term care, which has shifted the burden of care from institutions to the home. However, family caregivers have received less attention compared with care recipients. Many family caregivers are also older adults, and it is important that caregivers receive appropriate support to alleviate the burden of care. In rural and sub-urban area with limited resources compared to urban area, it is necessary to know which support to be prioritized. Therefore, this study aimed to understand family caregivers' perceptions of social support, the type and source of support which were considered important, and how it affected their caregiving burden and quality of life (QOL). We conducted a convergent mixed-method study with 174 primary family caregivers of older adults receiving home care in rural and suburb area of Central Japan. The mixed-method approach enabled qualitative data to complement quantitative results. Strong family support and higher education had positive effects on QOL, while higher caregiving burden and longer duration of care had negative effects on QOL. Provision of tangible support from family and healthcare professionals was central in reducing caregiving burden and improving caregivers' QOL. Support from distant relatives or neighbors, which was deemed inappropriate by caregivers, had a negative effect on caregivers' emotional status. In conclusion, family caregivers perceived support positively, but the effects depended on who provided support. While tangible support from close family and professionals was perceived positively, support from neighbors or distant relatives should consider caregivers' needs and condition to avoid a negative impact.

Children and adolescents in institutional care versus traditional families: a quality of life comparison in Japan.

BACKGROUND: A good quality of life (QOL) is important for the physical and mental well-being of all children. However, young people who live in an institutional setting may face different challenges than those who are raised in a traditional family. While a few quantitative studies of institutionalized children's QOL have been conducted, no research has investigated the QOL of young people living in Children's Homes (CHs) in Japan. This research compared the QOL of children and adolescents in Japan who live in CHs with that of children and adolescents living in traditional families. METHODS: A cross-sectional study was conducted in July 2016 with 204 students (grades three through nine), 47 of whom lived in a CH, and 157 of whom lived in a traditional family. Ages ranged from 8 to 15 years (CH: 55.8% Female, 44.2% Male; Traditional: 54.1% Female, 45.9% Male). Participants answered the kid-Kinder Lebensqualität Fragebogen (Translated from German: Children's quality of life questionnaire; KINDL®) Japanese Version, which covers six subscales of QOL; they filled in the questionnaires at home. Analysis of variance was used to compare QOL between the two samples. RESULTS: The total QOL score for all students (combined elementary school students and junior high school students) from CHs was statistically significantly lower than that for students from traditional families. Scores for the subscales, emotional well-being and family, were also significantly lower for CH young people than for those in traditional families. While elementary pupils in CHs reported lower QOL than those in traditional families, no significant differences in QOL were seen between junior high school students from CHs and their peers from traditional families. CONCLUSIONS: The findings presented support previous research showing that the QOL of elementary school students living in CHs is significantly lower than that of their peers in traditional families. However, this difference was not observed among junior high school students. This contrast suggests that QOL changes with age. Future research is needed to evaluate the determinants of QOL among all generations and family contexts.

What determines medical students' career preference for general practice residency training?: a multicenter survey in Japan.

BACKGROUND: Few studies have systematically explored factors affecting medical students' general practice career choice. We conducted a nationwide multicenter survey (Japan MEdical Career of Students: JMECS) to examine factors associated with students' general practice career aspirations in Japan, where it has been decided that general practice will be officially acknowledged as a new discipline. METHODS: From April to December 2015, we distributed a 21-item questionnaire to final year medical students in 17 medical schools. The survey asked students about their top three career preferences from 19 specialty fields, their demographics and their career priorities. Multivariable logistic regression was used to determine the effect of each item. RESULTS: A total of 1264 responses were included in the analyses. The top three specialty choice were internal medicine: 833 (65.9%), general practice: 408 (32.3%), and pediatrics: 372 (29.4%). Among demographic factors, "plan to inherit other's practice" positively associated with choosing general practice, whereas "having physician parent" had negative correlation. After controlling for potential confounders, students who ranked the following items as highly important were more likely to choose general practice: "clinical diagnostic reasoning (adjusted odds ratio (aOR): 1.65, 95% CI 1.40-1.94)", "community-oriented practice (aOR: 1.33, 95% CI 1.13-1.57)", and" involvement in preventive medicine (aOR: 1.18, 95% CI 1.01-1.38)". On the contrary, "acute care rather than chronic care", "mastering advanced procedures", and "depth rather than breadth of practice" were less likely to be associated with general practice aspiration. CONCLUSIONS: Our nationwide multicenter survey found several features associated with general practice career aspirations: clinical diagnostic reasoning; community-oriented practice; and preventive medicine. These results can be fundamental to future research and the development of recruitment strategies.

Development of an interprofessional competency framework for collaborative practice in Japan.

Rapid aging of the population necessitates improved collaboration among healthcare professionals. Unfortunately, interprofessional collaboration has yet to be implemented effectively in Japan. Therefore, we aimed to develop an interprofessional competency framework for Japanese healthcare professionals. The project was conducted as a four-step process, starting with initial categorization of potential competency domains,, followed by guiding principle and prototype development, feedback on the prototype, and final consensus. First, authors (JH and MO) collected opinions about competency in interprofessional collaboration at two academic meetings of the Japan Association for Interprofessional Education (JAIPE) and then analyzed the data thematically. Second, a project team consisting of JAIPE and University representatives extracted the domains and statements as prototype 1. Third, seven representatives from professional organizations joined the project team and developed prototype 2. We then called for feedback on the revised prototype 2 at both an open symposium and via public comments. Following revision of prototype 2, a new project team including 20 university, professional organization and health practitioner representatives finally discussed prototype 3, developed the final draft and reached a consensus. In analysis after collecting the data, we extracted 11 themes. We developed four key principles which applied to six domains as prototype 1-3. Finally, our competency framework included two core domains of "Patient-/client-/family-/community-centered" and "Interprofessional communication", and four peripheral domains of "Role contribution", "Facilitation of relationships", "Reflection" and "Understanding of others". We developed an interprofessional competency framework in Japan which consists of two core and four peripheral domains. The interprofessional competency framework is likely to affect the understanding of "high-context" and "relationalism" in Japanese healthcare. We hope that our interprofessional competency framework will encourage the systematic implementation of interprofessional education and collaboration in Japan.

Development of a questionnaire to measure primary care physicians' scope of practice.

BACKGROUND: Despite an increase in research devoted to primary care attributes, the patient benefits and educational aspects of broad scope practice of primary care physicians (PCPs) have not been well studied, due to a lack of validated measurement in each country. The objective of this study was to develop and validate the Scope of Practice Inventory (SPI) to measure physicians' scope of practice within the Japanese primary care setting. METHODS: The questionnaire was developed in seven phases: 1) item generation, 2) consensus method for necessity of each item, 3) Delphi process for the importance of each item, 4) pilot tests to limit the number of items, 5) preliminary cross-sectional study to examine factor structure and to validate the construct validity, 6) evaluation of internal consistency and intra-class reliability, and 7) evaluation of external validity. To confirm the interpretability of the SPI, the determinants of the SPI using a generalized linear model were evaluated. RESULTS: Among 359 items generated by a focus group, 180 reached a defined consensus on face and content validity after the Delphi process. After deletion of items with Kappa values less than 0.6, 120 items were selected for the preliminary study. The principle component analysis using responses from 451 PCPs eliminated 52 items. The final 68-point SPI had three subdomains: Inpatient care, 25 items; Urgent care and minor procedures, 27 items; and Ambulatory care, 16 items. Internal consistency and test-retest reliability for total SPI and each subdomain revealed acceptable reliability. Male sex, less years since graduation, working in a hospital, sub-urban or rural setting, having remote experience, and having board certification as a PCP were positively associated with higher SPI. CONCLUSIONS: We developed a self-administered 68-point scale, the SPI, which had satisfactory validity and reliability. Primary care quality and educational research using SPI are expected to contribute to comprehensive and efficient health care systems in the future.
