Background We previously showed that the number of publications in dermatology is increasing year by year, and positively correlates with improved economic conditions in mainland China, a still developing Asian country. However, the characteristics of publications in dermatology departments in more developed Asian countries such as Japan and South Korea are unknown. Methods In the present study, publications from 2003 through 2012 in dermatology in Japan, South Korea and mainland China were characterized. All data were obtained from www.pubmed.com. Results Dermatology departments in Japan published 4,094 papers, while mainland China and South Korea published 1528 and 1,758 articles, respectively. 48% of articles from dermatology in Japan were original research and 36% were case reports; The number of publications in Japan remained stable over time, but the overall impact factors per paper increased linearly over the last 10 year period (p < 0.05). In mainland China, 67% of articles from dermatology were original research, while 19% were case reports; The number of publications and their impact factors per paper increased markedly. In South Korea, 65% of articles from dermatology were original research and 20% were case reports. The impact factors per paper remained unchanged, despite of the fact that the number of publications increased over the last 10 year period (r2 = 0.6820, p = 0.0032). Only mainland China showed a positive correlation of the number of publications with gross domestic product per capita during this study period. Conclusions These results suggest that the total number of publications in dermatology correlates with economic conditions only in developing country, but not in more developed countries in Asia. The extent of economic development could determine both the publication quantity and quality. [ABSTRACT FROM AUTHOR]

Background: More new randomized controlled trials (RCTs) on acupuncture have been published in Japan since our last updated systematic review (2010). This systematic review aimed to evaluate the quality of RCTs on acupuncture conducted in Japan and understand the decade-wise changes in the methodological characteristics of the relevant RCTs. Methods: The literature search was performed using Ichushi Web, the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed and our team's compilation of relevant papers. We included full-length papers reporting RCTs that examined the clinical effects of acupuncture on patients in Japan published in or before 2019. We assessed the risk of bias (RoB), sample size, control setting, negative trial reporting, informed consent, ethics approval, trial registration, and adverse event reporting. Results: A total of 99 articles reporting 108 eligible RCTs were identified. The number of RCTs published in each decade was 1, 6, 9, 5, 40, and 47 in the 1960s, 1970s, 1980s, 1990s, 2000s, and 2010s, respectively. Quality assessment using the Cochrane RoB tool revealed that "sequence generation" improved in and after 1990 (73%–80% of RCTs were rated as "low") and "blinding of outcome assessors" slightly improved in and after the 2000s (40%–50% judged as "low"). However, "high" or "unclear" remained the dominant grades in other domains. Clinical trial registration and adverse events were reported only in 9% and 28% of the included RCTs even in the 2010s, respectively. A different acupuncture method or different point selection (e.g., deep vs. shallow insertion) was the most dominant control setting before 1990, while sham (or "placebo") needling and/or sham acupoints became the most dominant in the 2000s. The proportion of RCTs with positive results was 80% in the 2000s and 69% in the 2010s. Conclusions: The quality of RCTs on acupuncture conducted in Japan did not appear to have improved over the decades except for "sequence generation." While the culture of submitting negative trial reports was prevalent in the Japanese acupuncture research milieu as late as the 1990s, the overall quality of the relevant trials needs to be further improved.

Background: Sparganosis is a rare zoonotic disease caused by plerocercoid larvae of the genera Spirometra or Sparganum (Cestoda: Diphyllobothriidae). The larvae of Spirometra generally do not undergo asexual reproduction, whereas those of Sparganum can induce proliferative lesions in infected tissues. This paper presents an unusual case of proliferative sparganosis due to infection with Spirometra mansoni in a cat, normally considered a definitive host of the species. Case presentation: A 9-year-old male domestic cat was presented with a mass on the right side of the face that underwent progressive enlargement for 1 month. The morphological and histopathological examinations revealed multiple asexual proliferative cestode larvae in the lesions, suggestive of proliferative sparganosis. Next-generation sequencing analysis of formalin-fixed and paraffin-embedded specimens of surgically excised tissue indicated that the worm was Spirometra mansoni. Conclusion: Although S. mansoni a common tapeworm species found in the small intestine of domestic cats and dogs in Japan, proliferative sparganosis is extremely rare. This is the first confirmed case of proliferative sparganosis due to infection with S. mansoni in cat. [ABSTRACT FROM AUTHOR]

Background: Although internet-based stress management programs are proven effective in improving mental health among workers, micro- and small-sized enterprises (MSEs), lacking in occupational healthcare services, face challenges implementing them. To address this gap, this study will develop the program with stakeholders at MSEs to aim for real-world implementation. Objectives: This paper describes a study protocol for a pre-post feasibility study of an effectiveness-implementation hybrid type 2 trial of text-based internet-based programs ("WellBe-LINE") in MSEs with less than 50 employees. This feasibility study primarily aims to evaluate trial methods for future effectiveness-implementation hybrid type 2 trials. Methods: For this study protocol, an internet- and text-based self-care intervention program using the LINE app (a popular message tool in Japan) will be prepared according to evidence-based psychoeducational topics. Based on our online survey findings, personalized algorithms will be implemented according to employees' gender, age, and psychological distress levels. A personalized program using a popular pre-existing text app is expected to reduce employees' burdens and be attractive to them, resulting in successful implementation outcomes and mental health benefits. A pre-post design feasibility study will be conducted on ten companies to evaluate trial methods (e.g., recruitment and procedures). The primary outcome will involve individual-level penetration, defined as the proportion of the number of employees who register for the program divided by the total number of invited employees at the company. The progression criterion to go next trial specifies that more than 50% of the recruited companies obtain 60% individual penetration, which is set based on the findings of the prior survey of employees at MSEs and of interviews of stakeholders involved in this study, and will be measured by LINE system. Finally, acceptability, appropriateness, and feasibility will be measured using internet-based questionnaires and interviews. Discussion: This pre-post feasibility study for future effectiveness-implementation hybrid type 2 trials will provide in-depth knowledge about the successful implementation of text-based, semi-personalized, self-care mental health interventions in real-world settings using both quantitative and qualitative data. Conclusions: This feasibility study will help validate the effectiveness of text-based interventions using a widely used social networking service (SNS) tool for employees in MSEs.

Background: Preoperative education can improve postoperative quality of life in patients undergoing stoma surgery. However, the prevalence and when, where, and how preoperative education is implemented are unclear. Therefore, this study aimed to assess the current status of outpatient preoperative education for patients undergoing stoma surgery for rectal cancer as perceived by nurses. Additionally, it sought to identify the information provided by Japanese healthcare providers as a part of preoperative education. Methods: This cross-sectional study included 1,716 wound, ostomy, and continence nurses (WOCNs) in charge of stoma clinics at Japanese hospitals. Unsigned self-administered survey forms were mailed to the participants, and paper- or web-based responses were obtained. The main questions included: overview of the participants and their facilities, provision of outpatient preoperative education, status of implementation, and preoperative education components. To examine the factors associated with preoperative education, the independent variable was the presence or absence of preoperative education in the clinic, and the explanatory variables were the years of experience as a nurse, years of experience as a WOCN, type of hospital, number of beds, and number of intestinal stoma surgeries per year. Regression analysis was performed. Results: We received 773 valid responses (valid response rate: 45%). Duration of experience as a nurse and as a WOCN were 24.6 and 10.9 years, respectively. Outpatient preoperative education was provided by 24% of the participants. Most preoperative education sessions were conducted for patients or caregivers. Preoperative education took 31–60 min per patient, and one to five patients received preoperative education each month. Booklets, ostomy appliances, and stoma models/dolls were used as supplementary materials for preoperative education. The most frequently mentioned components of preoperative education were stoma care, daily life, social security, stoma clinic, traveling and going out, quality of life after stoma surgery, and precautions for medical treatment. In addition, education on the use of restrooms on the go, disaster preparedness, defecation disorders after restorative proctectomy, and complications after stoma closure were considered necessary. Conclusions: The implementation rate of outpatient preoperative education was low (24%). Future challenges include the development of specific educational content and procedures suitable for the Japanese medical environment and the establishment of preoperative medical care teams for stoma surgery to promote the provision of outpatient preoperative education.

Background: While research has explored the risk of periodontal disease in various eye conditions, the link between dry eye and periodontal disease remains underexplored, especially in Japanese adults. This study aims to investigate the association between dry eye and periodontal disease in community-dwelling Japanese adults. Methods: This study is a subset of the Uonuma cohort study, which includes Japanese adults aged 40 years and older residing in the Uonuma area of Niigata Prefecture, Japan. Participants completed a self-administered, paper-based questionnaire. Statistical analyses, including the chi-square test, independent t test, ANOVA test, and logistic regressions, were employed to assess the association of periodontal disease with independent variables. Results: Among 36,488 participants (average age 63.3 years, 47.4% men), 39.3% had a history of periodontal disease, and gender differences were statistically significant (p < 0.001). Significant associations were found between periodontal disease and dry eye diagnosis or symptoms. Univariable logistic regression revealed links between periodontal disease and age, gender, living status, alcohol consumption, remaining teeth, bite molar availability, and history of dry eye disease or symptoms. Multiple-adjusted regression found that doctor-diagnosed dry eye was associated with a higher likelihood of periodontal disease (odds ratio, 1.12; 95% confidence interval, 1.03–1.22). Participants who never experienced dryness or foreign body sensation had lower ORs of periodontal disease than those who always experienced such symptoms across all models. Conclusion: A significant correlation was found between dry eye and periodontal disease in Japanese adults. Regular check-ups, early detection, and effective management of both conditions are strongly recommended. [ABSTRACT FROM AUTHOR]

Background: Patients with Gaucher disease (GD), a rare lysosomal storage disorder, have reduced health-related quality of life (HRQOL). A patient-reported outcome measure (PROM) for HRQOL developed for type 1 GD (GD1) is not appropriate for patients with neuronopathic GD (nGD) types 2 (GD2) and 3 (GD3). In this study, we developed a new PROM for use in all GD types. We previously reported the qualitative analysis of interviews with Japanese patients with nGD, which was used to create nGD-specific PROM items. Here we evaluated the full PROM combining the type 1 questionnaire with the new nGD-specific items. Methods: Patients with confirmed GD were recruited (Association of Gaucher Disease Patients in Japan or leading doctors) for pre-testing (May 2021) or the main survey (October–December 2021). The PROM had three parts: Parts 1 and 2 were translated into Japanese from the pre-existing GD1 PROM, whereas Part 3 was newly developed. Patients (or their caregivers, where necessary) completed the PROM questionnaire on paper and returned it by mail. Mean scores were determined overall and by GD type. Inter-item correlations, content consistency (Cronbach's alpha), and test–retest reliability (Cohen's kappa; main survey only, taken 2 weeks apart) were calculated. Results: Sixteen patients (three with GD1; six with GD2; seven with GD3) and 33 patients (nine with GD1; 13 with GD2; 11 with GD3) participated in the pre-test and main survey, respectively. All GD2 patients and one-third (6/18) of GD3 patients required caregivers to complete the questionnaire. Mean scores indicated that the burden was highest in GD2 and lowest in GD1. In the main survey, internal consistency was high (Cronbach's alpha = 0.898 overall, 0.916 for Part 3), and test–retest reliability was high for Part 3 (kappa > 0.60 for 13/16 items) but low for Part 1 (kappa < 0.60 for 12/15 items). Conclusions: We have developed a flexible and reliable PROM that can be tailored for use in all types of GD and propose using Parts 1 and 2 for GD1, Parts 2 and 3 for GD2, and Parts 1, 2, and 3 for GD3.

Background: The Targeted Learning roadmap provides a systematic guide for generating and evaluating real-world evidence (RWE). From a regulatory perspective, RWE arises from diverse sources such as randomized controlled trials that make use of real-world data, observational studies, and other study designs. This paper illustrates a principled approach to assessing the validity and interpretability of RWE. Methods: We applied the roadmap to a published observational study of the dose–response association between ritodrine hydrochloride and pulmonary edema among women pregnant with twins in Japan. The goal was to identify barriers to causal effect estimation beyond unmeasured confounding reported by the study's authors, and to explore potential options for overcoming the barriers that robustify results. Results: Following the roadmap raised issues that led us to formulate alternative causal questions that produced more reliable, interpretable RWE. The process revealed a lack of information in the available data to identify a causal dose–response curve. However, under explicit assumptions the effect of treatment with any amount of ritodrine versus none, albeit a less ambitious parameter, can be estimated from data. Conclusions: Before RWE can be used in support of clinical and regulatory decision-making, its quality and reliability must be systematically evaluated. The TL roadmap prescribes how to carry out a thorough, transparent, and realistic assessment of RWE. We recommend this approach be a routine part of any decision-making process.

Background: Although midwives are expected to play a key role for psychological support throughout perinatal periods, their educational chances are limited. Versatile teaching strategies such as e-learning may be promising in expanding education. The objective of our study was to clarify the effects of an e-learning educational programme on midwives' empathic communication skills. Methods: From April 2019 to September 2019, a randomised controlled trial of a 1-day e-learning educational programme on perinatal psychological issues (both perinatal mental health assessment and empathic communication) was conducted to improve empathic communication skills of midwives and perinatal healthcare workers. Two types of measurements (paper-and-pencil multiple-choice test and video-viewing tests of simulated patient) were used to measure the competency of empathic communication skills. Results: Participants (N = 115) were randomly allocated to two groups (Intervention: n = 58, Control: n = 57). The intervention group was at a significantly higher level for both post-tests of empathic communication skills compared with the control group. Both intervention and control groups showed improvements in acquiring knowledge about perinatal mental health assessments. Conclusions: The results of our study show that a 1-day e-learning programme helped improve the midwives' empathic communications skills. Therefore, an effective 1-day e-learning educational programme of perinatal mental health will expand opportunity to learn about empathic communication skills for midwives and perinatal healthcare workers.

The public enquiry into the mass casualty incident at the Manchester Arena in the UK in which 23 people died and over 1000 were injured, identified the need for timely intramuscular administration of tranexamic acid to trauma patients. Since then, a number of studies and trials have been carried out and UK paramedics are now authorized to give intramuscular tranexamic acid in the pre-hospital setting. In Japan, pre-hospital administration by emergency life-saving technicians is not yet authorized, despite the fact that tranexamic acid was invented by Japanese scientists. In Japan, the need for the pre-hospital administration of tranexamic acid has been raised on several occasions, where a patient died from traumatic bleeding prior to hospital admission. This paper summarizes the evidence on the use of tranexamic acid in patients with traumatic bleeding, including new evidence on the intramuscular route. [ABSTRACT FROM AUTHOR]
