Observation of Acoustically Induced Dressed States of Rare-Earth Ions.

Acoustically induced dressed states of long-lived erbium ions in a crystal are demonstrated. These states are formed by rapid modulation of two-level systems via strain induced by surface acoustic waves whose frequencies exceed the optical linewidth of the ion ensemble. Multiple sidebands and the reduction of their intensities appearing near the surface are evidence of a strong interaction between the acoustic waves and the ions. This development allows for on-chip control of long-lived ions and paves the way to highly coherent hybrid quantum systems with telecom photons, acoustic phonons, and electrons.

Rural health dialogue for the sustainability of help-seeking behaviors among older patients: grounded theory approach.

BACKGROUND: Help-seeking behaviors (HSBs) are essential for disease prevention and health promotion. Dialogues with peers and medical professionals can improve HSBs, both qualitatively and quantitatively. Rural communities lacking healthcare resources require effective HSBs for healthcare sustainability. The current study aimed to investigate the effect of health dialogues between medical professionals and rural citizens on their HSBs. METHODS: All procedures complied with the Declaration of Helsinki and its subsequent amendments. The Unnan City Hospital Clinical Ethics Committee approved the study protocol (No. 20,220,002). A grounded theory approach was employed for the health dialogue participants in rural communities. Health dialogues with family physicians were conducted once a month at rural community centers. The dialogues and focus group interviews were recorded and coded to investigate changes in participants' perceptions and behaviors regarding HSBs. RESULTS: Twenty-one dialogues were conducted in two rural community centers, with a total of 112 participants. The average age of the participants was 70.2 years (standard deviation = 5.4), with 24% being males. Analysis of the grounded theory approach revealed four themes, namely joy-driven dialogue driving the realization of HSBs, reflection on personal HSBs through learning from others, revising HSBs based on rural social resources, and familiarity with physicians, hence motivating safe and secure HSBs. CONCLUSIONS: Mitigation of barriers between citizens and medical professionals and improvement of psychological safety in communities can drive effective HSBs in rural communities.

What Do Medical Students Learn about Community Care from Discussions with General Physicians? A Thematic Analysis.

Background and Objectives: Sustainable healthcare is fundamentally rooted in community medicine education. The COVID-19 pandemic disrupted global advancement in integrating traditional teaching and experiential learning. Additionally, an alarming decline in interest in community care has been observed among senior medical students. Here, we examined the perspectives on community care obtained from conversations with general physicians in rural medical universities. Materials and Methods: Using a constructivist lens, a qualitative methodology was employed to examine the perceptions of second-year medical students from Shimane University Medical School regarding community care, informed by dialogues with general physicians. We conducted a thematic analysis at Shimane University, Japan, an area known for its aging population. In 2023, 116 second-year students participated, none of whom had prior formal training in community care. The study was structured into three phases: (1) Pre-education: Students wrote essays about their initial understanding of community care, its advantages, disadvantages, and potential improvements; (2) Dialogue: Grouped by topic, students engaged in discussions that culminated in a comprehensive session with general physicians; and (3) Reflection: After discussions, students wrote essays reflecting any shift in their views on community care. A thematic analysis of essays from the pre-education and reflection phases provided a comparative perspective on the students' understanding. Results: Five dominant themes emerged from the thematic analysis: (1) Re-evaluating community care: Recognizing diversity and addressing societal challenges; (2) Interdisciplinary collaboration: Promoting shared roles and teamwork; (3) Learning and practice: Emphasizing hands-on experience and self-reflection; (4) Technological influence: The mutual relationship between community care and technological advancements; and (5) Challenges and resolutions: Identifying problems and crafting solutions. Conclusions: This study sheds light on the evolution of medical students' views on community care and underscores the importance of continuous adaptation in medical education programs.

Psychological safety and self-regulated learning through near-peer learning for the sustainability of rural community-based medical education: grounded theory approach.

INTRODUCTION: Difficulties in improving psychological safety in medical education can be attributed to the hierarchy among medical professionals. Near-peer learning (NPL) can increase learning between students and residents, and improve psychological safety. Rural community-based medical education (CBME) can use an NPL framework to improve psychological safety and compensate for the lack of resources, leading to sustainability. This qualitative study aimed to clarify the effects of NPL on the psychological safety and learning of medical trainees in rural CBME. METHODS: This study used a grounded theory approach. Thirty-eight medical students, 12 second-year residents, and eight family medicine residents participated in this study. Purposive sampling was used to address the research objectives, followed by ethnographic and semi-structured interviews. RESULTS: Three themes were identified: facilitating learning, change in perception, and change in learning. Rural NPL-based CBME drove learners' engagement in clinical practice through constant participation and reflection. Respecting and supporting learners' motivation and participation and effectively accepting them increased their sense of ownership and psychological safety. Furthermore, NPL supported participants in becoming self-regulated learners. CONCLUSION: Rural CBMEs lack healthcare and educational resources, but implementing NPL could make rural medical education sustainable, increasing the motivation of healthcare students and the number of medical staff working in rural contexts.

Risk Factors for Delayed Diagnosis of Acute Cholecystitis among Rural Older Patients: A Retrospective Cohort Study.

Background and objectives: Acute cholecystitis causes acute abdominal pain and may necessitate emergency surgery or intensive antibiotic therapy and percutaneous drainage, depending on the patient's condition. The symptoms of acute cholecystitis in older patients may be atypical and difficult to diagnose, causing delayed treatment. Clarifying the risk factors for delayed diagnosis among older patients could lead to early diagnosis and treatment of acute cholecystitis. This study aimed to explore the risk factors for delayed diagnosis of acute cholecystitis among rural older patients. Material and Methods: This retrospective cohort study included patients aged over 65 years diagnosed with acute cholecystitis at a rural community hospital. The primary outcome was the time from symptom onset to acute cholecystitis diagnosis. We reviewed the electronic medical records of patients with acute cholecystitis and investigated whether they were diagnosed and treated for the condition at the time of symptom onset. Results: The average ages of the control and exposure groups were 77.71 years (standard deviation [SD] = 14.62) and 80.13 years (SD = 13.95), respectively. Additionally, 41.7% and 64.1% of the participants in the control and exposure groups, respectively, were men. The logistic regression model revealed that the serum albumin level was significantly related to a time to diagnosis > 3 days (odds ratio = 0.51; 95% confidence interval, 0.28−0.94). Conclusion: Low serum albumin levels are related to delayed diagnosis of cholecystitis and male sex. The presence of abdominal pain and a high body mass index (BMI) may be related to early cholecystitis diagnosis. Clinicians should be concerned about the delay in cholecystitis diagnosis in older female patients with poor nutritional conditions, including low serum albumin levels, a low BMI, vague symptoms, and no abdominal pain.

Association between Self-Medication for Mild Symptoms and Quality of Life among Older Adults in Rural Japan: A Cross-Sectional Study.

Self-medication, a help-seeking behavior to control individual symptoms, can be promoted to prevent the overuse of medical care and improve self-management among older adults. However, evidence regarding the association between self-medication and quality of life (QOL) is lacking. The purpose of this study is to investigate the association between QOL and the usage of self-medication among rural older adults. This cross-sectional study included participants older than 65 years in rural Japanese communities. Data were collected using a questionnaire regarding self-medication trends, the EQ-5D-5L to assess QOL, and a demographics questionnaire. Participants were divided into exposure and control groups based on their tendencies toward self-medication usage. Differences in the demographics between groups were adjusted using propensity score matching. Results: The health status in the exposure group was statistically significantly better than that in the control group in the dimensions of movement, self-care, and usual activities. Conversely, the pain/discomfort and anxiety/depression dimensions were not statistically significantly different. The quality of self-medication behaviors for mild symptoms can be improved with practical knowledge of and access to home remedies and over-the-counter drugs. Educational interventions and system development for better self-medication for mild symptoms and medical care for critical symptoms in rural contexts can be effective in improving QOL among rural older adults.

Surgical Interventions in Cases of Esophageal Hiatal Hernias among Older Japanese Adults: A Systematic Review.

Background and Objectives: Given Japan's superaging population, an increasing number of older adults in the country need surgical treatment for esophageal hiatal hernias. Accordingly, this systematic review examines surgical interventions for symptomatic esophageal hiatal hernias in older Japanese patients and explores treatment outcomes. Materials and Methods: Articles on single operations for hiatal hernias published after 1991 were found on Google Scholar and Ichushi using specific keywords. Subsequently, articles fulfilling the predetermined inclusion criteria were considered in the study. Results: The mean patient age was 81.4 years, and the male-to-female ratio was 1:11.5. The main reasons for surgery were vomiting, dyspnea, and chest tightness. In terms of hernia classification, type IV was the most common (48%). Surgical modalities were laparoscopy in 15 cases, and laparotomy in 10 cases. Mean postoperative course was 26.47 days until hospital discharge, and there were no cases of perioperative death. Conclusions: Findings showed that multiple factors were involved in older adults' prognoses, and age was not the only biological factor. Therefore, aggressive surgical intervention should be considered for symptomatic older patients, even in the absence of surgery indicators.

Rare-Earth-Mediated Optomechanical System in the Reversed Dissipation Regime.

Strain-mediated interaction between phonons and telecom photons is demonstrated using excited states of erbium ions embedded in a mechanical resonator. Owing to the extremely long-lived nature of rare-earth ions, the dissipation rate of the optical resonance falls below that of the mechanical one. Thus, a "reversed dissipation regime" is achieved in the optical frequency region. We experimentally demonstrate an optomechanical coupling rate g_{0}=2π×21.7 Hz, and numerically reveal that the interaction causes stimulated excitation of erbium ions. Numerical analyses further indicate the possibility of g_{0} exceeding the dissipation rates of erbium and mechanical systems, thereby leading to single-photon strong coupling. This strain-mediated interaction, moreover, involves the spin degree of freedom, and has a potential to be extended to highly coherent opto-electro-mechanical hybrid systems in the reversed dissipation regime.

What resources do elderly people choose for managing their symptoms? Clarification of rural older people's choices of help-seeking behaviors in Japan.

BACKGROUND: Appropriate help-seeking behavior (HSB) that involves lay and professional care may moderate the usage of medical resources and promote good health, especially among the rural elderly. However, there is little evidence regarding the rural elderly's HSB choices for mild symptoms. Therefore, this study attempts to bridge this gap. METHODS: The participants were patients living in rural areas and over the age of 65, who attended Japanese clinics and general hospitals. In Phase 1, monthly diaries and one-on-one interviews about their mild symptoms and HSB were used to establish HSB items and assess its content validity. Content analysis helped determine the items. In Phase 2, participants were asked to complete the list to measure HSB. The answers to the list and HSB mentioned in the diaries were compared to evaluate concurrent validity. Retests were conducted to examine the content's reliability and test-retest reliability. RESULTS: Phase 1 included 267 participants (average age = 75.1 years, standard deviation [SD] = 4.3; 50.1% male). The diary collection rate was 97.6%. Of the participants, 70.4% used lay care and 25.4% used professional care. Content analysis identified eight types of lay care and four types of professional care. Phase 2 included 315 participants (average age = 77.7 years, SD = 8.27; 46.0% male). In terms of validity, the results of the list and the diaries were correlated (Spearman r 0.704; p < 0.001). The most common behavior with mild symptoms was consulting with primary care physicians, followed by self-care and using home medicine. The test-retest reliability for mild symptoms found kappa values of 0.836 for lay care and 0.808 for professional care. CONCLUSIONS: The choices of HSB for mild symptoms clarified identified in this study have high validity and reliability. Therefore, it can be used to assess the relationships between HSB and health conditions and the effectiveness of health promotion on rural older people's HSB.

Systematic scoping review of factors and measures of rurality: toward the development of a rurality index for health care research in Japan.

BACKGROUND: Rural-urban health care disparities are an important topic in health services research. Hence, developing valid and reliable tools to measure rurality is needed to support high quality research. However, Japan, has no index to measure rurality for health care research. In this study, we conducted a systematic scoping review to identify the important factors and methodological approaches to consider in a rurality index to inform the development of a rurality index for Japan. METHODS: For our review, we searched six bibliographic databases (MEDLINE, PubMed, CINAHIL, ERIC, Web of Science and the Grey Literature Report) and official websites of national governments such as Government and Legislative Libraries Online Publications Portal (GALLOP), from 1 January 1989 to 31 December 2018. We extracted relevant variables used in the development of rurality indices, the formulas used to calculate indices, and any measures for reliability and validity of these indices. RESULTS: We identified 17 rurality indices from 7 countries. These indices were primarily developed to assess access to health care or to determine eligibility for incentives for health care providers. Frequently used factors in these indices included population size/density and travel distance/time to emergency care or referral centre. Many indices did not report reliability or validity measures. CONCLUSIONS: While the concept of rurality and concerns about barriers to access to care for rural residents is shared by many countries, the operationalization of rurality is highly context-specific, with few universal measures or approaches to constructing a rurality index. The results will be helpful in the development of a rurality index in Japan and in other countries.

Realist evaluation of interprofessional education in primary care through transprofessional role play: what primary care professionals learn together.

Interprofessional collaboration (IPC) is vital to primary care. Improving IPC requires cooperation between medical and other healthcare professionals. Transprofessional role plays can enhance the quality of IPC; thus, in this study, we conducted transprofessional role plays, based on existing theories regarding IPC and medical education, with healthcare professionals in primary care. As a study design, the realist approach was used to clarify the effectiveness of transprofessional role plays. Five Likert-scale questionnaires regarding the competency of IPC were used to assess the change in perception of medical and care professionals through educational intervention. The realist approach was employed for the clarification of contexts, mechanisms and outcomes of transprofessional role play using one-on-one interview data. Sixty-two medical care professionals participated in the transprofessional role plays, and 31 participants were interviewed. The difference in the score of the competency scale of IPC was statistically significant in all six competencies (p-value <0.001). Three context, mechanism and outcome theories were clarified from the qualitative analysis of the interviews: reflection on others, realisation of own roles and driving humanistic relationship. Additionally, contextual factors, the mechanisms that facilitated them and the clarified outcomes were identified. Ultimately, in this realist evaluation transprofessional role plays proved to be effective in driving IPC in primary care through improving compassion and reliability across professions. The constant provision of the role play and mutual discussion of each professional's role can facilitate effective IPC in primary care.

Improvement in palliative care quality in rural nursing homes through information and communication technology-driven interprofessional collaboration.

INTRODUCTION: Information and communication technology (ICT) can facilitate long-term care. In long-term care, effective communication among healthcare professionals is vital to reduce inappropriate emergency transfer and eventual death in hospitals. As nursing homes in rural areas lack adequate healthcare resources, ICT can reduce the burden on professionals, leading to adequate long-term care. This study investigated whether the application of ICT-based communication can reduce the number of emergency transportations to, and death in, hospitals in rural facilities. METHODS: This was an interventional study. Participants were patients living in a rural nursing home in the westernmost part of Unnan City in Shimane prefecture, Japan. The intervention group was defined as patients living therein after application of the ICT system and the control group as patients living therein before application of the ICT system. The primary outcome was the rate of emergency transportation to hospitals and the secondary outcome was the rate of death in the nursing home. RESULTS: The total number of participants was 96 (48 in the ICT usage group and 48 in the control group), and the average age of this sample was 89.5 years. The rate of emergency transportation was 54.2% (26/48) in the control group and 29.2% (14/48) in the intervention group (p=0.022). The rate of end-of-life care in the nursing home was 33.3% (3/9) in the control group and 84.6% (11/13) in the intervention group (p<0.001). CONCLUSION: ICT-driven nursing home care can reduce emergency transportation from nursing homes and enable patients in nursing homes to remain there longer, leading to an increase in end-of-life care in nursing homes, which provides hope to patients and their families. Therefore, these findings highlight that the continuous provision of ICT can facilitate end-of-life care in nursing homes.

Predicting factors of elderly patients' discharge to home after rehabilitation in rural Japan: a retrospective cohort study.

INTRODUCTION: The aging of society continues to progress in Japan. As aging is more pronounced in rural than in urban societies, rehabilitation can contribute to rural elderly patients' discharge to home after hospitalization for various causes. The relationship between rural elderly patients' improvement of motor and cognitive function in relation to activities of daily life (ADL) through rehabilitation and their discharge to home has not been clarified in rural communities. The purpose of this study was to clarify whether an improvement of ADL can enable elderly hospitalized patients to discharge to their homes in a rural community. METHODS: This retrospective cohort study included 783 consecutive patients aged over 65 years with frailty and multimorbidity who were admitted with acute diseases and underwent active rehabilitation at a rural community hospital. This study was conducted from April 2016 to March 2020. The following patient data were collected from the electronic medical records: age, sex, body mass index, serum albumin, diagnosis on admission, the Charlson Comorbidity Index, living with family or alone, duration of disease from the onset of symptoms to the start of rehabilitation, duration of rehabilitation, care level based on the Japanese insurance system, cognitive and motor components of the functional independence measure (FIM) as the measurement of the level of ADL at both admission and discharge, change in these components of the FIM, and the place to which patients were discharged (home or facility). Two groups of patients were distinguished based on whether the discharge was to home or a facility. Logistic regression was performed to investigate the relationships between patients' characteristics and the effects of rehabilitation determined as a change in the FIM on one hand and to where patients were discharged on the other. The variables with statistically significant differences in the logistic regression were further analyzed to calculate sensitivity, specificity and likelihood ratio with the area under the curve for predicting discharge to home. RESULTS: Patients' average age was 82.1 years, and 33.5% were male. A high score in the motor component of the FIM after rehabilitation and short duration of rehabilitation were statistically related to discharge to home. The cognitive component of the FIM was not associated with discharge to home. The motor-FIM cutoff after rehabilitation was calculated to be 60, resulting in sensitivity, specificity and positive likelihood ratio to predict discharge to home of 0.86, 0.78, and 4.00, respectively. CONCLUSION: This study showed that elderly patients' motor aspect of ADL after rehabilitation in rural community hospitals might predict discharge to home in rural settings. Rehabilitation in rural community hospitals can be effective in rural elderly patients with frailty and multimorbidity. The improvement in physical abilities was more important than cognitive functions for the effective discharge of the elderly patients in this study to their rural homes. By respecting patients' and their families' desires, effective rehabilitation may enable elderly patients to live at home.

Home care workers' judgments about users' acute conditions: A qualitative study on interprofessional collaboration.

Home care workers' (HCWs) approaches to home care users' acute symptoms are critical for users' safety and quality of life. However, the processes of these approaches are unclear. This study investigates how HCWs assess users' conditions. Focus group discussions and semi-structured interviews with HCWs were conducted in a rural Japanese city. HCWs' decisions were affected by interactions and previous relationships with care managers, home care nurses, physicians, and users' families. Rural HCWs act flexibly, changing the professionals and families they consult with. Understanding HCWs' behaviors and improving relationships among medical/care professionals and families can improve management of users' acute conditions.

Challenges and solutions in the continuity of home care for rural older people: A thematic analysis.

Home care is essential for the continuity of care, but rural communities struggle to procure these services regularly. As rural populations age, these difficulties may be exacerbated. This study examines the challenges and solutions for offering home care in rural areas. Healthcare professionals held focus groups and one-on-one interviews in rural communities, and these interviews were recorded and analyzed using thematic analysis. Changing rural contexts, stakeholder relationships, and sustainable communities were the primary themes. Increasing knowledge, sharing information, and dialogue among stakeholders were also crucial. Collaboration between professions may also create more sustainable home care in rural communities.

Gatekeeping function of primary care physicians under Japan's free-access system: a prospective open cohort study involving 14 isolated islands.

BACKGROUND: Gatekeeping is important for strong primary care and cost containment. Under Japan's free-access system, patients can access any medical institution without referral, which makes it difficult to evaluate the gatekeeping function of primary care physicians (PCPs). OBJECTIVES: To examine the gatekeeping function of PCPs in Japan, we compared the frequencies of visits to primary care clinics, referrals to advanced care and hospitalizations between 14 remote islands and a nationwide survey. METHODS: This study was a prospective, open cohort study involving 14 isolated islands (12 238 inhabitants) in Okinawa, Japan. Participants were all patients who visited the clinics on these islands in 1 year. Main outcome measures were the incidence of on-island clinic visits and referrals to off-island advanced care. RESULTS: There were 54 741 visits to the islands' clinics with 2045 referrals to off-island medical facilities, including 549 visits to emergency departments and 705 hospitalizations. The age- and sex-standardized incidences of healthcare use per 1000 inhabitants per month were: 360.0 (95% confidence interval: 359.9 to 360.1) visits to primary care clinics, 11.6 (11.0 to 12.2) referrals to off-island hospital-based outpatient clinics, 3.3 (2.8 to 5.2) visits to emergency departments and 4.2 (3.1 to 5.2) hospitalizations. Comparison with the nationwide survey revealed a lower incidence of visits to hospital-based outpatient clinics in this study, while more patients had visited PCPs. CONCLUSIONS: The lower incidence of visits to secondary care facilities in this study might suggest that introduction of a gatekeeping system to Japan would reduce the incidence of referral to advanced care.

Care managers in rural Japan: Challenges to interprofessional collaboration.

Effective interprofessional collaboration for care managers is vital for the care of older people. This study's aim was to inquire into the obstacles to interprofessional collaboration faced by care managers in rural areas of Japan. Forty-six care managers participated in group discussions and semi-structured interviews, and the qualitative data were analyzed using thematic analysis. Five themes related to obstacles emerged from the analysis regarding relationships with physicians, professional competency, relationships among other professionals, environmental constraints, and relationships with nonprofessionals. Other professionals' unfamiliarity with the care manager's role and a lack of mutual understanding, boundaries, and information sharing among medical professionals were also cited as issues.

Inquiry into short-term learning on Japanese rural islands: a qualitative study.

BACKGROUND: Community-based medical education (CBME) improves the learning of medical students. The outcomes depend on the circumstances in which students learn. So far, there has been no study on the short-term learning experienced by medical students on rural islands in Japan; hence, we specifically explored this in the case of islands in Okinawa. METHODS: We conducted one-on-one semi-structured interviews with seven medical students and three focus groups, each comprising three medical students. All subjects underwent a three-day clinical training on the rural islands of Okinawa, Japan. All sessions were audio-recorded and transcribed verbatim. We analysed the contents of the interview using the Steps for Coding and Theorisation. RESULTS: Ten concepts were extracted and four themes generated: 1) rural resources and environments, 2) interaction with inhabitants, 3) rural physicians' skills, and 4) proposed revisions. These themes and concepts provide valuable insights into the dynamics of medical care on rural islands as well as the benefit of this experience for students trained in urban contexts. The participants learned the importance of collaborating with multiple professionals in ways specific to each rural context. By interacting with various islanders, they developed an understanding of the different cultural backgrounds in which rural physicians work and their ability to adapt to each. This experience motivated them to pursue studies on rural medicine upon return to the mainland. CONCLUSION: This study shows that a short-term learning experience on rural islands in Japan may help medical students understand specific rural resources and their importance, the interconnections among the inhabitants, and the competency of primary care physicians.

Dynamic Control of the Coupling between Dark and Bright Excitons with Vibrational Strain.

We numerically and experimentally investigate strain-induced coupling between dark and bright excitons and its dynamic control using a gallium arsenide (GaAs) micromechanical resonator. Uniaxial strain induced by the mechanical resonance efficiently detunes the exciton energies and modulates the coupling strength via the deformation potential in GaAs. This allows optical access to the long-lived dark states without using any external electromagnetic field. This field-free approach could be expanded to a wide range of solid-state materials, leading to on-chip excitonic memories and circuits based on micromechanical resonators.

Challenges for Japanese rural home care workers in interprofessional collaboration: a qualitative study.

Among medical professionals, the role of home care workers is crucial in the care of patients in their homes. In Japan, however, research on the difficulties home care workers face while working in rural zones is limited. Using thematic analysis, a qualitative study was conducted with 57 home care workers in a rural area of Japan. Findings revealed the difficulties they experienced regarding the medical problems of their patients and in their relationships with other professionals. The old customs of rural medicine and the system of long-term care insurance strongly influence relationships among multiprofessionals, leading to conflict and hierarchy.
