Abstract Objective We aimed to validate the Japanese version of the Patient Health Questionnaire-4 (PHQ-4-J). People in Japan, especially healthcare workers (HCWs) suffer from high rates of mental health symptoms. The PHQ-4 is an established ultra-brief mental health measure used in various settings, populations and languages. The Japanese version of the PHQ-4 has not been validated. Methods Two hundred eighty people in Japan (142 HCWs and 138 from the general public) responded to the PHQ-4-J. Internal consistency, and factorial validity were assessed using confirmatory factor analysis (CFA) and Multiple Indicators Multiple Causes (MIMIC) models. Results Internal consistency was high (α = 0.70–0.86). CFA yielded very good fit indices for a two-factor solution (RMSEA = 0.04, 95% CI 0.00–0.17) and MIMIC models indicated the performance differed between HCWs and the general population. Conclusions The PHQ-4-J is a reliable ultra-brief scale for depression and anxiety in Japanese, which can be used to meet current needs in mental health research and practice in Japan. Disaster research and gerontology research can benefit from this scale, enabling mental health assessment with little participant burden. In practice, early detection and personalised care can be facilitated by using the scale. Future research should target specific populations in Japan during a non-emergency time.

IntroductionRelocation after a disaster often has negative health effects on vulnerable people, particularly older adults. However, little is known about the number of repeated evacuations and relocations after disasters among those experienced disaster-related deaths. This case series aimed to summarize the secondary problems and mortality risks in patients involved in relocation after disasters.MethodsWe analyzed and summarized the data on 520 disaster-related deaths in Minamisoma City, a municipality near the Fukushima Daiichi Nuclear Power Plant, focusing on the number of relocations. Herein, we describe the cases of three individuals over 80 years old, who died after eight or more relocations, which were certified as disaster-related deaths.ResultsWe discuss following three cases, which are (1) a female patient in her 90s who had a stroke and was completely disabled, (2) a female patient in her 80s whose cancer was detected later due to her failing to see her family doctor, and (3) a male patient in his 80s whose regular postoperative treatment was disrupted following cancer recurrence.DiscussionOur findings indicate that evacuation led to the worsening of chronic diseases and eventually to post-disaster death. Prolonged wide-area evacuation and repeated relocation likely interrupted the continuum of care and led to the failure of adequate care provision. To reduce the loss of human life, it is necessary to review the number of wide-area evacuations and relocations over the medium to long term after large-scale disasters, including nuclear disasters, which may occur in the future. Simultaneously, it is important to establish a medical system at the evacuation site so that disaster victims can continue to receive medical care even after evacuation or relocation.

BackgroundHealth information seeking via the internet among patients with cancer in disaster-affected areas is underresearched. ObjectiveThis study aims not only to assess the extent and means of web-based health information seeking among patients with cancer living in the disaster-affected area of the 2011 Fukushima triple disaster but also to compare these patterns with those without cancer, identifying distinct and shared factors influencing their web-based health information behaviors. MethodsWe surveyed 404 patients (263 with and 141 without cancer) from the surgery department outpatient office at Minamisoma Municipal General Hospital, from October 2016 to January 2017. The survey included self-administered questions on internet and digital device use. Descriptive analyses were performed to examine the use patterns of digital devices and the internet and their impact on health information seeking across different age groups of patients with and without cancer. Multivariable logistic regression was used to examine factors associated with web-based health information seeking, stratifying by cancer diagnosis. ResultsThe proportion of participants who sought health information on the internet was comparable between patients with cancer and patients without cancer (19% vs 17.4%; P=.71). Digital device use varied significantly with age, with peak smartphone use occurring among the youngest cohorts for both groups. Multivariable logistic regression revealed that patients with cancer using smartphones or tablets daily were significantly more likely to gather web-based health information (odds ratio [OR] for smartphones 3.73, 95% CI 1.58-8.80; OR for tablets 5.08, 95% CI 1.27-20.35). Trust in institutional websites also significantly influenced web-based health information gathering among patients with cancer (OR 2.87, 95% CI 1.13-7.25). Conversely, among patients without cancer, unemployment was associated with a lower likelihood of seeking web-based health information (OR 0.26, 95% CI 0.08-0.85), whereas trust in both institutional and personal websites significantly increased this likelihood (OR for institutional websites 6.76, 95% CI 2.19-20.88; OR for personal websites 6.97, 95% CI 1.49-32.58). ConclusionsThis study reveals that a small proportion of both patients with cancer and patients without cancer engage in health information seeking via the internet, influenced by age, digital device use, and trust in institutional websites. Given the growing prevalence of digital literacy, strategies to enhance accessible and reliable web-based health information should be developed, particularly for patients with cancer in postdisaster settings. Future efforts should focus on tailored health communication strategies that address the unique needs of these populations.

Patients undergoing hemodialysis are particularly vulnerable to severe outcomes of SARS-CoV-2 infection, with mortality rates higher than that of the general population. Vaccination reduces the risk of adverse outcomes, with booster doses being particularly beneficial. However, limited data are available on the effectiveness of subsequent vaccinations or their effect on increasing antibody levels. This single-center study aimed to investigate changes in SARS-CoV-2 IgG antibody titers following the fourth vaccination among 28 patients undergoing hemodialysis. Blood tests were conducted at various intervals post-vaccination, with a focus on identifying factors associated with antibody levels. The IgG antibody levels rapidly increased by Day 7 post-vaccination, with a median time to peak of 11 days. Antibody titers tended to be higher in male patients than in female patients. This study sheds light on the immune response to the fourth vaccination in patients undergoing hemodialysis. As this study included a small sample size, with a short observation period, further research is warranted to comprehensively understand the effectiveness of vaccination and the benefits of additional doses of vaccine.

IntroductionVaccination has been implemented as a useful measure to combat the COVID-19 pandemic. However, there is a tendency for individuals to avoid vaccination due to the possibility of adverse events, making it important to investigate the relationship between COVID-19 vaccines and their adverse events. This study explored longitudinal adverse event patterns and factors that influence adverse events following the second to fourth doses of the COVID-19 vaccine through a latent class analysis.MethodsParticipants were recruited from the Fukushima Prefecture and included individuals who had completed four doses of the COVID-19 mRNA vaccine. This study utilized data from questionnaire surveys and blood collection conducted between September 2021 and November 2022. In the questionnaire, factors such as sex, age, medical history, medication, type of vaccine administered, and adverse events following vaccination were recorded. Additionally, in the blood data, serological tests [IgG(S)] and cellular immune responses (T-spot) were measured. Descriptive statistics, latent class analysis, multivariable logistic regression, and multiple regression analyses were performed to identify the longitudinal adverse event patterns and influencing factors. By analyzing adverse events over time, we identified two distinct groups: those less prone to experiencing adverse events (Group 1) and those more susceptible (Group 2) to latent class analysis.ResultsA total of 1,175 participants were included after excluding those without any adverse events. The median age of the participants in Group 1 was 70 years, and in Group 2 it was 51 years. The proportion of female participants was 298 in Group 1 and 353 in Group 2. Patients in Group 2 were significantly younger (p

Abstract Regulatory authorities must balance ensuring evidence of efficacy and safety of new drugs. Various regulatory pathways, such as the accelerated approval program in the United States (US), allow authorities to quickly approve drugs for severely ill patients by granting market authorization based on surrogate end points and pending confirmatory trials. In this cross‐sectional study, we considered 23 indications of cancer drugs that received accelerated approval by the US Food and Drug Administration (FDA) but were subsequently withdrawn as of April 2023. Our investigation extended to assessing the regulatory status of these accelerated approvals in the European Union (EU) and Japan, examining relevant regulatory documents and identifying factors contributing to the withdrawal in the United States. Comparing regions, we found that for 52% (12/23) and 30% (7/23) of withdrawn accelerated approvals in the United States, sponsors had also sought marketing authorization from the European Medicines Agency (EMA) and Japan's Pharmaceuticals and Medical Devices Agency (PMDA), respectively. As of the April 30, 2023 study cutoff date, 83% (10/12) of drug–indication pairs remained approved by the EMA, while the PMDA retained 100% (7/7). For these indications, the time from FDA withdrawal until the study cutoff date ranged from 0.23 years to 11.45 years for EMA approvals (median: 1.28 years) and 1.10 years to 11.45 years for PMDA approvals (median: 3.22 years). These findings highlight substantial regulatory discrepancies concerning cancer drugs with unconfirmed benefits. Addressing these discrepancies may involve requiring pharmaceutical companies to confirm clinical benefits using more robust end points and fostering international harmonization in regulators' assessment.

Natural disasters pose significant challenges to affected communities, particularly vulnerable populations such as older adults. The aftermath of the Great East Japan Earthquake highlighted the necessity of welfare shelters to provide essential care. However, little is known about the specific role of physical therapists in these shelters. The aim of this article is to share the experiences and contributions of physical therapists in a welfare shelter in Wajima, Ishikawa Prefecture, immediately after the 2024 Noto Peninsula earthquake. The earthquake, with a magnitude of 7.6, damaged 76,589 houses, injured over 1,100 people, resulting in 245 deaths. The authors comprised a multidisciplinary team, including physical therapists, that provided short-term medical support at a welfare shelter in Wajima. Through several examples, we describe the contribution of physical therapists to evacuees' health outcomes. Physical therapists played multifaceted roles in the welfare shelter, optimizing living environments, conducting physical screenings, and delivering continuous medical care, including respiratory care and exercise programs. The involvement of physical therapists in post-disaster evacuation shelters is crucial for enhancing emergency health care delivery and promoting community resilience.

Following the Great East Japan Earthquake (GEJE) and the Fukushima Daiichi nuclear power plant accident in 2011, mandatory evacuation orders were issued to residents living near the nuclear power plant in Fukushima prefecture, including some patients receiving home oxygen therapy. Although the vulnerability of patients with home oxygen therapy (one of the population groups most vulnerable to disasters) has been noted, there is little information on the health effects of evacuation in the event of a radiation disaster. A 90-year-old man diagnosed with chronic obstructive pulmonary disease since the age of 70, and lived in a town located approximately 20 km south of the nuclear power plant, died 8 months after the disaster due to worsening health conditions. This case reveals the potential for both physical and psychological burdens experienced by vulnerable groups like patients undergoing home oxygen therapy during evacuations in times of disaster. Although it is only a case report and the information is limited, severe respiratory distress requiring home oxygen therapy may present a significant risk factor for disaster-related deaths, especially in cases where evacuations are prolonged, such as in nuclear disasters. Due to the challenge of obtaining prompt public support immediately after a disaster, home oxygen therapy patients may need to prioritize self-help and mutual assistance in their disaster preparedness efforts.

Abstract The medical situation during disasters often differs from that at usual times. Disasters can lead to significant mortality that can be difficult to monitor. The types of disaster-related deaths are largely unknown. In this study, we conducted a survey to categorize the disaster-related deaths caused by a radiation disaster. A total of 520 people living in Minamisoma City, Fukushima Prefecture, at the time of the Fukushima Daiichi Nuclear Power Plant accident, who were certified to have died due to disaster-related causes were surveyed. We divided the participants into those who were at home at the time of the earthquake and those who were in hospitals or facilities when the disaster struck and conducted a hierarchical cluster analysis of the two groups. Disaster-related deaths could be divided into seven groups for those who were at home at the time of the disaster and five groups for those who were in hospitals or facilities at the time of the disaster. Each group showed different characteristics, such as "the group with disabilities," "the group receiving care," and "the group with depression," and it became evident that not only uniform post-disaster support, but support tailored to the characteristics of each group is necessary.

Abstract Predicting the transition of kidney function in chronic kidney disease is difficult as specific symptoms are lacking and often overlooked, and progress occurs due to complicating factors. In this study, we applied time-series cluster analysis and a light gradient boosting machine to predict the trajectories of kidney function in non-dialysis dependent chronic kidney disease patients with baseline estimated glomerular filtration rate (GFR) ≥ 45 mL/min/1.73 m2. Based on 5-year changes in estimated GFR, participants were stratified into groups with similar trajectories by cluster analysis. Next, we applied the light gradient boosting machine algorithm and Shapley addictive explanation to develop a prediction model for clusters and identify important parameters for prediction. Data from 780 participants were available for analysis. Participants were classified into five classes (Class 1: n = 78, mean [± standard deviation] estimated GFR 100 ± 19.3 mL/min/1.73 m2; Class 2: n = 176, 76.0 ± 9.3 mL/min/1.73 m2; Class 3: n = 191, 59.8 ± 5.9 mL/min/1.73 m2; Class 4: n = 261, 52.7 ± 4.6 mL/min/1.73 m2; and Class 5: n = 74, 53.5 ± 12.0 mL/min/1.73 m2). Declines in estimated GFR were 8.9% in Class 1, 12.2% in Class 2, 4.9% in Class 3, 12.0% in Class 4, and 45.1% in Class 5 during the 5-year period. The accuracy of prediction was 0.675, and the top three most important Shapley addictive explanation values were 1.61 for baseline estimated GFR, 0.12 for hemoglobin, and 0.11 for body mass index. The estimated GFR transition of patients with preserved chronic kidney disease mostly depended on baseline estimated GFR, and the borderline for estimated GFR trajectory was nearly 50 mL/min/1.73 m2.

Background Financial relationships between healthcare institutions and pharmaceutical companies can lead to conflicts of interest (COIs), potentially compromising patients’ care. In Japan, scholarship donations, unique type of payments made to healthcare institutions and their subunits by pharmaceutical industries without restricting their use including non-educational or research purpose, may often have implicit promotional purposes. However, detailed information about these payments remains scarce.Methods This study employed a cross-sectional design to analyse the extent and distribution of all scholarship donations made by all 73 pharmaceutical companies belonging to the Japan Pharmaceutical Manufacturers Association (JPMA) to healthcare institutions in 2017. Data were obtained from publicly available sources from the companies, and the totalnumber of payments, their distributions across various institutions and specialties were analysed.Results A total of 27 007 payment contracts amounting to $178 703 721 in scholarship donations were made to 4839 specific departments and laboratories at 251 different institutions by 67 pharmaceutical companies. National universities received 50.8% of total payments. All universities setting medical school in Japan received one or more payments. Domestic pharmaceutical companies contributed to $137 797 302 (77.1%) in total. Clinical medicine departments received 89.6% ($160 113 147) with 6.2% ($11 011 946) and 2.0% ($3 600 456) allocated to basic medicine and social medicine specialties, respectively.Conclusion This study provided a comprehensive overview of scholarship donations from pharmaceutical companies to healthcare institutions in Japan, revealing significant financial support primarily directed to national universities and clinical medicine departments. Japanese policy-makers should consider implementing regulations that promote transparency and mitigate potential COIs arising from scholarship donations, which may be useful in other countries with similar schemes.

Idiopathic normal pressure hydrocephalus in elderly people is considered a form of glymphopathy caused by malfunction of the waste clearance pathway, called the glymphatic system. Tau is a representative waste material similar to amyloid-β. During neurodegeneration, lipocalin-type prostaglandin D synthase (L-PGDS), a major cerebrospinal fluid (CSF) protein, is reported to act as a chaperone that prevents the neurotoxic aggregation of amyloid-β. L-PGDS is also a CSF biomarker in idiopathic normal pressure hydrocephalus and significantly correlates with tau concentration, age, and age-related brain white matter changes detected by magnetic resonance imaging. To investigate this glymphopathy, we aimed to analyze white matter changes and contributing factors in vivo and their interactions ex vivo. Cerebrospinal tap tests were performed in 60 patients referred for symptomatic ventriculomegaly. Patients were evaluated using an idiopathic normal pressure hydrocephalus grading scale, mini-mental state examination, frontal assessment battery, and timed up-and-go test. The typical morphological features of high convexity tightness and ventriculomegaly were measured using the callosal angle and Evans index, and parenchymal white matter properties were evaluated with diffusion tensor imaging followed by tract-based spatial statistics. Levels of CSF biomarkers, including tau, amyloid-β, and L-PGDS, were determined by ELISA, and their interaction, and localization were determined using immunoprecipitation and immunohistochemical analyses. Tract-based spatial statistics for fractional anisotropy revealed clusters that positively correlated with mini-mental state examination, frontal assessment battery, and callosal angle, and clusters that negatively correlated with age, disease duration, idiopathic normal pressure hydrocephalus grading scale, Evans index, and L-PGDS. Other parameters also indicated clusters that correlated with symptoms, microstructural white matter changes, and L-PGDS. Tau co-precipitated with L-PGDS, and colocalization was confirmed in postmortem specimens of neurodegenerative disease obtained from the human Brain Bank. Our study supports the diagnostic value of L-PGDS as a surrogate marker for white matter integrity in idiopathic normal pressure hydrocephalus. These results increase our understanding of the molecular players in the glymphatic system. Moreover, this study indicates the potential utility of enhancing endogenous protective factors to maintain brain homeostasis.

IntroductionPrevious studies demonstrated that the surgical productivity regressed in 2020. This study therefore explored whether the COVID-19 pandemic had any significant lasting effect of reducing the surgical productivity in Japan. This is a retrospective observational study which is an extension of the previous ones.MethodsThe authors analyzed 18,805 surgical procedures performed during the study period from April 1 through September 30 in 2016–22. A non-radial and non-oriented Malmquist model under the variable returns-to-scale assumptions was employed. The decision-making unit (DMU) was defined as a surgical specialty department. Inputs were defined as (1) the number of assistants, and (2) the surgical duration. The output was defined as the surgical fee. The study period was divided into 42 one-month periods. The authors added all the inputs and outputs for each DMU during these study periods, and computed its Malmquist index, efficiency change and technical change. The outcome measures were its annual productivity, efficiency, and technical changes between the same months in each year.ResultsThere was no statistically significant difference in annual productivity, efficiency, and technical changes between pre-pandemic and post-pandemic periods.DiscussionNo evidence was found to suggest that the COVID-19 pandemic has any significant lasting effect of reducing the surgical productivity.

IntroductionThe health of patients with mental disorders, such as alcohol-related diseases, often deteriorates after disasters. However, the causes of death among those with alcohol-related diseases during and after radiation disasters remain unclear.MethodsTo minimize and prevent alcohol-related deaths in future radiation disasters, we analyzed and summarized six cases of alcohol-related deaths in Minamisoma City, a municipality near the Fukushima Daiichi nuclear power plant.ResultsPatients were generally treated for alcohol-related diseases. In one case, the patient was forced to evacuate because of hospital closure, and his condition worsened as he was repeatedly admitted and discharged from the hospital. In another case, the patient’s depression worsened after he returned home because of increased medication and drinking for insomnia and loss of appetite.DiscussionThe overall findings revealed that, in many cases, evacuation caused diseases to deteriorate in the chronic phase, which eventually resulted in death sometime after the disaster. To mitigate loss of life, alcohol-related diseases must be addressed during the chronic phases of future large-scale disasters, including nuclear disasters.

Abstract Background Tuberculosis (TB) is endemic in many low‐income countries, which can affect the spine in 1%–5% of those with an active infection. This study reports the clinical characteristics of patients admitted for spinal TB in Kabul, Afghanistan, a country with very limited resources. Methods This was a descriptive study among 26 patients treated for spinal TB in three major referral hospitals in Kabul, Afghanistan, between March 2019 and April 2020. The sociodemographic and clinical details, gender, age, site of infection, presenting complaints, signs, and symptoms of the patients were retrieved from their medical records. Summary statistics were analyzed using SPSS version 20. Ethics approval was obtained from the ethics committee of Shahid Beheshti University of Medical Sciences in Tehran, Iran. Results Data were available for 26 patients with spinal TB admitted consecutively. The mean age of the sample was 38.2 years (SD 17.5), and there were 16 males and 10 females. Median time from symptom onset to hospital admission was 60 days. The most common diagnostic imaging technique used was magnetic resonance imaging (92.3%), followed by computed tomography (7.7%). The majority of the lesions involved the lumbar spine (61.4%), followed by the thoracolumbar spine (30.8%). Back pain was the most common manifestation in 21 patients (80.8%), and varying degrees of neurological impairment were found in 16 (61.5%) patients. There were no deaths among the patients up to the discharge date. Conclusions This study describes the clinical characteristics of spinal TB among patients in Kabul, Afghanistan. It is essential to strengthen preventive strategies and to improve health awareness about clinical features of spinal TB in patients with chronic back pain even in the absence of signs of TB.

The COVID-19 pandemic and the shift of power to the Taliban have negatively affected women-owned companies. This study aimed to explore the external and internal challenges of women-owned businesses from March 2020 to January 2022 in Afghanistan. In-depth semi-structured interviews were conducted from December 2021 to January 2022 with 29 women-owned company owners and chief executive officers (CEOs) based in five provinces of Afghanistan. Data were analyzed using thematic analysis. The themes are COVID-19 external challenges: movement restriction, inability to access the market, and financial issues. COVID-19 internal challenges: financial and production problems. Taliban governance external challenges: regulation on women’s activities, economic crisis, and market downturn, and Taliban governance internal challenges: financial issues, production issues, and staff mental wellbeing. The study concluded that challenges due to the COVID-19 and Taliban governance presented strong shocks to women-owned companies that may precipitate the closure of these companies or the immigration of businesswomen.

Abstract There are prevalent financial relationships between dermatologists and pharmaceutical companies in Japan. However, little was known about the extent of whole picture of the personal payments made to dermatologists by pharmaceutical companies. This study aimed to examine the personal payments to the board-certified dermatologists by the Japanese Dermatological Association from the pharmaceutical companies between 2016 and 2019. Using the publicly disclosed payments data by the pharmaceutical companies between 2016 and 2019, we evaluated the magnitude, prevalence, and trends in the personal payments made to all board-certified dermatologists for the lecturing, writing, and consulting compensations. The payments were descriptively analyzed overall and by dermatologist demographics. Additionally, the payment trends were assessed by generalized estimating equation models. Of 6883 active board-certified dermatologists, 3121 (45.3%) received a total of $33,223,806 personal payments between 2016 and 2019. The median per-physician payments and number of payments (interquartile range) were $1737 ($613–$5287) and 4.0 (2.0–10.0) over the 4 years, respectively. Only top 1%, 5%, 10% of dermatologists received 41.7% (95% confidence interval [CI] 38.2–45.1%), 76.9% (95% CI 74.7–79.1%), and 87.6% (95% CI 86.2–88.9%) of overall payments. The number of dermatologists receiving payments and per-dermatologist payments increased by 4.3% (95% CI 3.1‒5.5%, p

Abstract Little is known about how crises might affect the long-term uptake of breast cancer screening programs. This study aimed to clarify the long-term trend of breast cancer screening program uptake in Minamisoma City following the 2011 Triple Disaster in Fukushima, Japan (earthquake, tsunami, and nuclear disaster), and to evaluate the factors associated with this uptake. This study retrospectively analyzed data from the Basic Resident Registry and Breast Cancer Screening Program in Minamisoma City following the Triple Disaster. We calculated the annual breast cancer screening uptake rate for women aged 40–74 years who were of an even-numbered age at the end of each fiscal year and the incidence of at least one instance of uptake of the breast cancer screening initiative during the biennial intervals. We further performed cross-sectional and longitudinal regression analyses for the biannual screening uptake and investigated its associated factors. Breast cancer screening participation rates were 19.8% and 18.2% in 2009 and 2010, respectively. They decreased to 4.2% in 2011, and gradually increased thereafter, reaching the pre-disaster level of 20.0% in 2016. Similar but longer decrease of the uptake was observed in the biannual screening uptake rate. No pre-disaster screening uptake between 2009 and 2010, those living alone, or those who were evacuated, were factors that were found to be associated with non-uptake of the breast cancer screening program following the 2011 disaster. This study showed a long-term decline in breast cancer screening uptake in the area affected by the Triple Disaster, which was the most severe among those under evacuation, those who were isolated, and those without previous uptake. The insights emerging from this study could be used to increase awareness of this issue and establish potential countermeasures.

Abstract Background Self-regulation of payment disclosure by pharmaceutical industry trade groups is a major global approach to increasing transparency of financial relationships between drug companies and healthcare professionals and organisations. Nevertheless, little is known about the relative strengths and weaknesses of self-regulation across countries, especially beyond Europe. To address this gap in research and stimulate international policy learning, we compare the UK and Japan, the likely strongest cases of self-regulation of payment disclosure in Europe and Asia, across three dimensions of transparency: disclosure rules, practices, and data. Results The UK and Japanese self-regulation of payment disclosure had shared as well unique strengths and weaknesses. The UK and Japanese pharmaceutical industry trade groups declared transparency as the primary goal of payment disclosure, without, however, explaining the link between the two. The rules of payment disclosure in each country provided more insight into some payments but not others. Both trade groups did not reveal the recipients of certain payments by default, and the UK trade group also made the disclosure of some payments conditional on recipient consent. Drug company disclosure practices were more transparent in the UK, allowing for greater availability and accessibility of payment data and insight into underreporting or misreporting of payments by companies. Nevertheless, the share of payments made to named recipients was three times higher in Japan than in the UK, indicating higher transparency of disclosure data. Conclusions The UK and Japan performed differently across the three dimensions of transparency, suggesting that any comprehensive analysis of self-regulation of payment disclosure must triangulate analysis of disclosure rules, practices, and data. We found limited evidence to support key claims regarding the strengths of self-regulation, while often finding it inferior to public regulation of payment disclosure. We suggest how the self-regulation of payment disclosure in each country can be enhanced and, in the long run, replaced by public regulation to strengthen the industry’s accountability to the public.

Abstract Overactive bladder (OAB) significantly reduces quality of life. The primary goal of this study was to determine whether the gender combination of patient and physician may be associated with satisfaction with OAB treatment. This questionnaire survey was conducted at Jyoban Hospital. We considered the adult patients aged 18 years or older who attended the outpatient office of the urology department of the hospital, were diagnosed with OAB and had been taking anticholinergics or β3‐receptor stimulants, or both, for at least 3 months. In addition to the OAB treatment satisfaction, the questionnaire covered OABSS, IPSS, oral medications, effectiveness of OAB treatment, response to OAB symptoms, and the medium and extent of information collection. A total of 147 patients participated in the study. In summary, 91 (61.9%) were male, and the mean age was 73.5 years. Compared to when the gender of doctor and patient was not the same, female patients tended to be significantly more satisfied when they were treated by female doctors (OR 10.79, 95% CI 1.27–92.05). On the other hand, no similar trend was observed when male patients were treated by male doctors (OR 1.26, 95% CI 0.25–6.34). In the present study, which examined doctor–patient gender combinations in satisfaction with OAB treatment, as hypothesized, satisfaction was higher for female doctor–female patient combinations compared to different doctor–patient genders. A notable fact was that similar associations were not observed among the male doctor–patient combination. This means that an embarrassment of female patients could be stronger than male patients particularly in disclosing urinary symptoms to healthcare providers. The percentage of female urologists in Japan is only 8.2%, and it will be necessary to further promote the recruitment of female doctors in urology fields in order to encourage female patients with OAB to more actively visit doctors.

IntroductionFollowing the Great East Japan Earthquake, the living environment of socially isolated older adults has become a pressing concern. In response, Nagaya, a collective housing program, was established in Soma City, Fukushima, Japan to address social isolation among older adults and support their long-term health. This study aimed to identify characteristics of individuals in Nagaya and examine the sustainability of this initiative.MethodsWe conducted a retrospective analysis of residents who were relocated to Nagaya, emphasizing their characteristics, the continuity of their stay in Nagaya, and their care certification levels, using data up to December 31, 2022. We employed Kaplan–Meier curves to analyze the duration for which residents continued to reside in Nagaya and the time leading up to the requiring care-level certification.ResultsOf 65 people who moved to Nagaya after the disaster, 30 people (46.2%) continued to live there, 21 (32.3%) died during their stay, and 14 (21.5%) moved out. The overall duration of occupancy averaged 6.39 years (SD 3.83 years). The proportion of requiring care-level certification occurrences per person-year was 0.0577 for those without care certification and 0.3358 for those with requiring support level at the time of moving in.ConclusionIn summary, Nagaya-style communal housing may offer suitable living environments for older adults with diverse needs during disasters and serve as a valuable tool for developing public policies in aging societies.

In breast cancer surgery, some medical facilities lack the necessary resources to conduct sentinel lymph node biopsy and its intraoperative frozen section consultation. In the coastal rural area of Fukushima, Japan, which has suffered from physician undersupply following the 2011 triple disaster of earthquake, tsunami and nuclear disaster, we explored the feasibility of telepathology by evaluating the diagnostic accuracy in remote intraoperative frozen section consultation of sentinel lymph node biopsy and its required time. Although examination time has room for improvement, telepathology can be one possible solution in resource-limited areas.

Key Clinical Message During disasters, multiple factors can cause significant delays in medical visits. Regular patient monitoring, high‐risk individual alerts, and telemedicine enhancements can potentially alleviate these issues and ensure timely interventions. Abstract During the COVID‐19 pandemic, a Japanese woman in her 70s delayed her regular breast cancer checkup for over 2 years. During disasters, health priorities tend to decline, necessitating proactive measures from healthcare providers, such as augmenting collaboration among healthcare professionals and identifying high‐risk individuals.

Abstract Background After a disaster, it is essential to maintain the health care supply levels to minimize the health impact on vulnerable populations. During the 2011 Fukushima Daiichi Nuclear Power Plant accident, hospitals within a 20 km radius were forced to make an immediate evacuation, causing a wide range of short- and long-term health problems. However, there is limited information on how the disaster disrupted the continuity of health care for hospitalized patients in the acute phase of the disaster. Case presentation An 86-year-old Japanese man who needed central venous nutrition, oxygen administration, care to prevent pressure ulcers, skin and suctioning care of the trachea, and full assistance in the basic activities of daily living had been admitted to a hospital within 5 km radius of Fukushima Daiichi Nuclear Power Plant and experienced Fukushima Daiichi Nuclear Power Plant accident. After the accident, the hospital faced a manpower shortage associated with hospital evacuation, environmental changes caused by infrastructure and medical supply disruptions, and the difficulty of evacuating seriously ill patients. As a result, antibiotics and suction care for aspiration pneumonia could not be appropriately provided to the patient due to lack of caregivers and infrastructure shortages. The patient died before his evacuation was initiated, in the process of hospital evacuation. Conclusions This case illustrates that decline in health care supply levels to hospitalized patients before evacuation during the acute phase of a radiation-released disaster may lead to patient fatalities. It is important to maintain the health care supply level even in such situations as the radiation-released disaster; otherwise, patients may experience negative health effects.

In the US, research has established that a funding relationship exists between pharmaceutical industries and physicians, particularly cardiologists. This study aimed to fill a research gap via an in-depth data analysis of the impact that the coronavirus 2019 restrictions had on this dynamic. The payments per cardiologist declined by 55.7% (95% confidence interval: 52.0%‒-59.0%, P < 0.001) in monetary amounts, and by 66.6% (95% confidence interval: 66.1%-67.1%, P < 0.001) in the number of payments right after the COVID-19 pandemic onset, respectively. Cardiologists must consider the ethical implications of the potential for their clinical practice to be influenced by industry payments. Résumé: Aux États-Unis, la recherche a établi l’existence d’une relation de financement entre l’industrie pharmaceutique et les médecins, particulièrement les cardiologues. Cette étude visait à combler une lacune dans la recherche grâce à une analyse approfondie des données concernant les répercussions des restrictions relatives à la COVID-19 sur cette dynamique. Les rétributions versées par cardiologue ont baissé de 55,7 % (intervalle de confiance [IC] à 95 % : 52,0 % à 59,0 %, p < 0,001) en argent et de 66,6 % (IC à 95 % : 66,1 % à 67,1 %, p < 0,001) en nombre de versements, juste après le début de la pandémie de COVID-19. Les cardiologues doivent considérer les implications éthiques liées à l’influence potentielle de ces versements sur leur pratique.

Abstract Background The purpose of this study is to compute surgical total factor productivity with Malmquist index, and to evaluate the effects of states of emergency against the novel coronavirus disease 2019 (COVID-19) pandemic on its productivity change. We hypothesized that the states of emergency significantly reduced surgical total factor productivity in Japan. Methods The authors collected data from all the surgical procedures performed in Teikyo University Hospital from April 1 through September 30 in 2019–21. Non-radial and non-oriented Malmquist model under the variable returns-to-scale assumptions was employed. The decision making unit (DMU) was defined as a surgical specialty department. Inputs were defined as (1) the number of medical doctors who assisted surgery, and (2) the duration of surgical operation from skin incision to closure. The output was defined as the surgical fee for each surgery. The study period was divided into fifty-one ten- (or eleven-) day periods. We added all the inputs and outputs of the surgical procedures for each DMU during these study periods, and computed its Malmquist index, efficiency change and technical change. Results Seven thousand nine hundred and thirty-one surgical procedures were analyzed. The overall productivity and efficiency progressed significantly both during states of emergency and during no states of emergency. Our subgroup analysis demonstrated that there were no surgical specialties that had significantly different productivity, efficiency or technical changes between states of emergency and no states of emergency. Conclusions We demonstrated that the surgical productivity did not suffer despite the states of emergency against the COVID-19 pandemic in Japan.

Epstein-Barr virus (EBV) encephalitis is caused by initial infection or reactivation of EBV. In adults, the risk factors of EBV encephalitis include human immunodeficiency virus infection, immunosuppressant drugs, congenital immune deficiencies, post-stem cell transplantation, and post-solid organ transplantation. However, a few cases of adult-onset EBV encephalitis without these risk factors were also reported. The efficacy of steroid or intravenous immunoglobulin remains unclear in the treatment of EBV encephalitis. Herein, we report a case of an 82-year-old man with fever and disturbance of consciousness who was diagnosed as having EBV encephalitis. Gadolinium-enhanced magnetic resonance imaging showed punctate enhancement in the bilateral basal ganglia, which resembled chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS). Symptoms and enhanced lesions improved after immunotherapy. Immunotherapy may be effective in the treatment of EBV encephalitis with CLIPPERS-like lesions.

BackgroundDistributing COVID-19 vaccines to the public was an important task for the governments of each country. Because of various limitations, priority settings for vaccination were determined at the time of mass vaccination. However, trends between vaccine intention and uptake, as well as reasons for getting vaccinated or not getting vaccinated, among these groups were understudied, undermining verification of the legitimacy of priority selection. ObjectiveThis study aims to illustrate a trend from prior COVID-19 vaccine intention, when the vaccine was not available, to the actual uptake within 1 year when all residents had access to the vaccine, to illustrate a change of reason for getting vaccinated or not getting vaccinated and to examine whether priority settings predicted subsequent vaccination uptake. MethodsProspective cohort, web-based, self-administered surveys were conducted in Japan at 3 time points: February 2021, September to October 2021, and February 2022. In total, 13,555 participants (age: mean 53.1, SD 15.9 years) provided valid responses, with a 52.1% follow-up rate. On the basis of the information obtained in February 2021, we identified 3 types of priority groups: health care workers (n=831), people aged ≥65 years (n=4048), and those aged 18 to 64 years with underlying medical conditions (n=1659). The remaining patients were treated as nonpriority (n=7017). Modified Poisson regression analysis with a robust error estimated the risk ratio for COVID-19 vaccine uptake after adjusting for socioeconomic background, health-seeking behavior, attitude toward vaccines, and COVID-19 infection history. ResultsIn February 2021, a total of 5182 out of 13,555 (38.23%) respondents expressed their intention to get vaccinated. In February 2022, a total of 1570 out of 13,555 (11.6%) respondents completed the third dose and 10,589 (78.1%) respondents completed the second dose. Prior vaccine intention and subsequent vaccine coverage rates were higher in the priority groups. Protection of themselves and their families from potential infection was the most frequent reason for getting vaccinated, whereas concern about side effects was the most frequent reason for hesitation across the groups. Risk ratios for received, reserved, or intended for vaccination in February 2022 were 1.05 (95% CI 1.03-1.07) for the health care worker group, 1.02 (95% CI 1.005-1.03) for the older adult group, and 1.01 (95% CI 0.999-1.03) for the preexisting conditions group compared with the nonpriority group. Prior vaccine intention and confidence in vaccines were strong predictors of vaccine uptake. ConclusionsThe priority settings at the start of the COVID-19 vaccination program had a significant impact on vaccine coverage after 1 year. The priority group for vaccination achieved higher vaccination coverage in February 2022. There was room for improvement among the nonpriority group. The findings of this study are essential for policy makers in Japan and other countries to develop effective vaccination strategies for future pandemics.

Objectives Limited evidence is available regarding the financial relationships between gastroenterologists and pharmaceutical companies in Japan. This study analysed the magnitude, prevalence and trends of personal payments made by major pharmaceutical companies to board-certified gastroenterologists in Japan in recent years.Design Cross-sectional analysisSetting and participants Using payment data publicly disclosed by 92 major pharmaceutical companies, this study examined the non-research payments made to all board-certified gastroenterologists by the Japanese Society of Gastroenterology.Primary and secondary outcome measures The primary outcomes were payment amounts, the prevalence of gastroenterologists receiving payments, yearly trends in per-gastroenterologist payment values and the number of gastroenterologists with payments. Additionally, we evaluated the differences in payments among influential gastroenterologists, including clinical practice guideline authors, society board member gastroenterologists and other general gastroenterologists.Results Approximately 52.8% of all board-certified gastroenterologists received a total of US$89 151 253, entailing 134 249 payment contracts as the reimbursement for lecturing, consulting and writing, from 84 pharmaceutical companies between 2016 and 2019. The average and median payments per gastroenterologist were US$7670 (SD: US$26 842) and US$1533 (IQR: US$582–US$4781), respectively. The payment value per gastroenterologist did not significantly change during the study period, while the number of gastroenterologists with payments decreased by −1.01% (95% CI: −1.61% to −0.40%, p

Objectives This study aimed to identify factors that delayed emergency medical services (EMS) in evacuation order zones after the 2011 Great East Japan Earthquake and Fukushima Daiichi Nuclear Power Plant accident and to investigate how the lifting of the evacuation affected these factors over time.Design This research was a retrospective observational study. The primary outcome measure was onsite EMS time. A gradient boosting model and a decision tree were used to find the boundary values for factors that reduce EMS.Setting The target area was Minamisoma City, Fukushima, Japan that was partly designated as an evacuation order zone after the 2011 Fukushima disaster, which was lifted due to decreased radiation.Participants This study included patients transferred by EMS from 1 January 2013 through 31 October 2018. Patients who were not transported and those transported for community events, interhospital patient transfer and natural disasters were excluded.Outcome measures This study evaluated the total EMS time using on-site time which is the time from arrival at the scene to departure to the destination, and other independent factors.Results The total number of transports was 12 043. The decision tree revealed that the major factors that prolonged onsite time were time of day and latitude, except for differences by year. While latitude was a major factor in extending on-site time until 2016, the effect of latitude decreased and that of time of day became more significant since 2017. The boundary was located at N37.695° latitude.Conclusions The onsite time delay in EMS in evacuation order zones is largely due to regional factors from north to south and the time of day. However, the north-south regional factor decreased with the lifting of evacuation orders.

Highlights Whether the incidence and timing of dementia is affected by an interaction of sex with cardiovascular diseases (CVD) events is unclear. We evaluated the sex-specific difference in dementia risk associated with CVDs, including its unique interaction with social, behavioral, genetic, and medical factors. Women with coronary heart disease and heart failure were 1.6 and 1.3 times more likely to develop Alzheimer’s disease than men with the same condition. Men with heart failure had 1.4 times higher risk of having vascular dementia than women. Socioeconomic, lifestyle, genetic, and medical factors moderated the sex-specific association between CVD and dementia.

Abstract Background Afghanistan, a low-income landlocked country, is continuously suffering from domestic war and conflicts; the country struggles to provide quality healthcare services, including affordable medicinal products in the required quantity. Moreover, the quality standards of domestic pharmaceutical companies have not been established yet. One of the internationally recognized guidelines for monitoring manufacturing processes in pharmaceutical companies is Good Manufacturing Practice (GMP), recommended by World Health Organization (WHO). Therefore, this study aimed to assess whether a pharmaceutical company in Kabul, Afghanistan adheres to the GMP standards established by WHO. Method A descriptive cross-sectional study was conducted to assess the WHO-delineated GMP compliance of 25 pharmaceutical companies in Kabul, Afghanistan. The inspection checklist was developed by Afghanistan's National Medicine and Healthcare Products Regulatory Authority (NMHRA) using the WHO-delineated GMP guidelines. In addition, direct observation, interviews with respective delegates, and documentation reviews were conducted to collect research data. Result Only 38.33% (1.14 ± 1.08) of GMP contents were complied. Personnel 66.67% (2 ± 1.15) and materials 58.67% (1.76 ± 1.11) were the most commonly complied components, whereas the product recall 12.98% (0.39 ± 0.85), quality assurance 16.44% (0.49 ± 0.81) and quality control laboratory 28.35% (0.85 ± 1.12) were the least complied ones. Conclusion None of the GMP components was fully adhered to by the pharmaceutical companies in Kabul, Afghanistan. Quality control and assurance should be implemented immediately, including validation and qualification practices.

Abstract Objective To evaluate the magnitude, prevalence, and trend of the financial relationship between Japanese head and neck surgeons and pharmaceutical companies between 2016 and 2019. Study Design Cross‐sectional analysis. Setting Japan. Methods This study evaluated personal payments concerning lecturing, consulting, and writing paid by 92 major pharmaceutical companies to all Japanese head and neck surgeons board‐certified by the Japan Society for Head and Neck Surgery between 2016 and 2019. The payments were descriptively analyzed and payment trend were assessed using population‐averaged generalized estimating equations. Further, the payments to board executive board members with specialist certification were also evaluated separately. Results Of all 443 board‐certified head and neck surgeons in Japan, 365 (82.4%) received an average of $6443 (standard deviation: $12,875), while median payments were $2002 (interquartile ranges [IQR] $792‐$4802). Executive board specialists with a voting right received much higher personal payments (median $26,013, IQR $12,747‐$35,750) than the non‐executive specialists (median $1926, IQR $765‒$4134, p

Background. Mental health problems can significantly impact a student’s academic performance, career, health, and future if they are not identified and managed in time. The poor mental health of young people is a global problem, including in Nepal. However, the scenario of perceived stress among adolescent students residing in academic hostels is not explored in Nepal. Therefore, this study aimed at determining the prevalence of perceived stress with its associated predictors, experienced stressors, and coping mechanisms among adolescent students residing in private hostels in Nepal. Methods. A cross-sectional study design was employed among all adolescent students of grades six to ten who resided in eight school hostels in Nepal. A total of 209 students responded to self-administered validated questionnaires for perceived stress (PSS-10) and coping scales. Results. More than half (51.67%) of the students experienced symptoms of perceived stress. Strict discipline in the hostel (77.03%) and groupism based on religion (5.26%) were the most common and least common stressors experienced, respectively. One-third of the students (n=70, 33.5%) very often felt confident about handling personal problems. The presence of a mischievous element and neglect from friends were significant stressors determined. Seeking social support was the most used coping strategy over externalizing behaviours such as using bad words, yelling, and shouting. Conclusion. The study confirmed the presence of perceived stress among students living in hostels, where hostel residential factors were the predominant predictors. As a minority of the students can properly manage their stress, it is necessary to provide students with the appropriate educational counselling to help them deal with potential obstacles. Additionally, monitoring, increased communication with family and friends, and improving the hostel environment can be important in addressing students’ perceived stress.

Abstract Background The present study aimed to develop and test an extended theory of planned behavior (TPB), which includes attitudes, subjective norms and perceived behavioral control, oral health knowledge, and past oral health behavior on the intention to improve oral health behaviors among primary school students in Shanghai, China. Methods A school-based cross-sectional study was conducted with 414 students in the third-grade from 10 classes of Mingqiang Primary School located in Shanghai, China. Participants were recruited in October 2019. Data were collected through self-reported questionnaires, consisting of demographic characteristics, TPB variables, oral health knowledge and past oral health behaviors. Exploratory factor analysis was used to analyze TPB items. Pearson’s correlation and hierarchical regression analyses were conducted to identify the associated factors of intention to improve oral health behaviors. Results The study showed that among students in the third grade, attitudes, subjective norms, perceived behavioral control, and past oral health behaviors were associated with the intention to improve oral health behaviors. In the hierarchical regression analysis, age and sex were entered in Model 1 which significantly explained 3.00% of the variance (F = 6.26, p

Abstract Colorectal cancer (CRC) screening is a well-established cancer screening method, and its effectiveness depends on maintaining a high participation rate in the target population. In this study, we analyzed the trends in CRC screening participation rates over 10 years in Minamisoma City, where residents were forced to evacuate after the 2011 triple disaster in Fukushima, Japan. The immunochemical fecal occult blood test is provided as municipal CRC screening. We calculated the annual CRC screening participation rate and analyzed the factors associated with participation in screening. Overall, 4069 (12.3%) and 3839 (11.7%) persons participated in CRC screening in 2009 and 2010, respectively; however, the number decreased significantly to 1090 (3.4%) in 2011 when the earthquake occurred. Over the following 3 years, the rate gradually recovered. Multivariable logistic analysis showed that age

Abstract Little is known about how the psychological stress of having experienced a natural disaster affects cancer patients. We experienced a patient who was treated with breast cancer after having been stricken by a typhoon, which resulted in significant psychological damage. Treatment strategies should incorporate patients' mental health appropriately after disasters.

Introduction An easy-to-access and effective psychotherapy for bereaved informal caregivers has not been established.

This study aimed to examine the feasibility of online self-compassion focused psychotherapy for bereaved informal caregivers.Method and analysis A total of 60 study participants will undergo an intervention programme comprising online sessions of 2 hours per week for five consecutive weeks and undertake postsession work. The intervention personnel will comprise psychologists who have received more than 10 hours of structured training. The primary endpoint will be assessed on the intervention completion rate, with secondary endpoints consisting of the Complicated Grief Questionnaire, Patient Health Questionnaire-9, Generalised Anxiety Disorder-7, Brief Resilience Scale and Self-Compassion Scale. Evaluations will be conducted preintervention, immediately after intervention, and 4 and 12 weeks after intervention.Ethics and dissemination This study has been reviewed and approved by the Ethics Committee of the Kyoto University Graduate School and Faculty of Medicine, Kyoto University Hospital, Japan (Approved ID: C1565). The results of this study will be disseminated through publication in a peer-reviewed journal and conference presentations.Trial registration number UMIN000048554.

Objectives: This study aims to clarify the financial burden of health on the elderly. Out-of-pocket payment (OOPP) in a major private general hospital in Phnom Penh was considered an indicator of financial burden. Study design: This study is a three-year cross-sectional study. Methods: To investigate the characteristics of patients who visited the Sunrise Japan Hospital (SJH), their data were obtained from the electronic reception database. Results: A total of 119,938 patients who visited SJH from January 2017 to September 2019 were included. The median age (25th, 75th centiles) was 52 years (36, 66) and 38.31% of patients were aged over 60 years. The OOPP median (25th, 75th centiles was 73.78 USD (32, 161.89). The median OOPP was the lowest in the 20s and highest in the 90s. The OOPP of an emergency patient was the highest in the consultation classifications. Conclusions: The need to raise public awareness regarding the financial burden on the elderly is becoming increasingly urgent. It is vital to establish a social system to prevent the medical catastrophes.

Abstract The health status of healthy decontamination workers employed after the Fukushima nuclear disaster remains unclear. This study aimed to evaluate the prevalence of non-communicable diseases among such workers. In this observational study, questionnaires on lifestyle and social factors were administered as part of a health promotion program for decontamination workers in 2016 in Minamisoma City, Fukushima. The questionnaires and health check-up results were compared with those of the 2016 National Health and Nutrition Examination Survey (NHANES) in Japan. Overall, 123 male decontamination workers were enrolled; 93 (75.6%) were drinkers, and 84 (68.3%) were current smokers. The age-adjusted prevalence (95% confidence interval) of hypertension, dyslipidemia, diabetes mellitus, and obesity were 27.2% (20.1–34.4%), 30.4% (22.6–38.2%), 11.3% (5.5–17.1%), and 49.0% (39.0–58.9%), respectively. The age-adjusted prevalence in the NHANES were 32.8% (31.1–34.5%), 16.1% (14.5–17.6%), 7.0% (6.2–7.7%), and 31.2% (29.9–32.5%), respectively. The prevalence of obesity, dyslipidemia, binge drinking, and smoking were higher in healthy male decontamination workers than in the general population. Decontamination workers in disaster-struck areas may have higher risks of developing non-communicable diseases, possibly due to their original health status. Continuous monitoring of their health status and proper interventions are warranted.
