Abstract Background Congenital limb deficiency is a rare and intractable disease, which impairs both function and appearance of the limbs. To establish adequate medical care, it is necessary to reveal the actual conditions and problems associated with this disease. However, there have been no extensive epidemiological surveys in Japan addressing this disease. This is the first nationwide epidemiological survey of congenital limb deficiency in this country. Methods With the cooperation of epidemiology experts, we performed a two-stage nationwide survey to estimate the number of patients with congenital limb deficiency and reveal basic patient features. We targeted orthopaedic surgery, paediatric, and plastic surgery departments. Hospitals were categorized according to the institution type and the number of hospital beds; hospitals were randomly selected from these categories. We selected 2283 departments from a total 7825 departments throughout Japan. In this study, we defined congenital limb deficiency as partial or total absence of the limbs, proximal to the proximal interphalangeal joint of the fingers/lesser toes or interphalangeal joint of the thumb/great toe. We distributed the first survey querying the number of initial patient visits from January 2014 to December 2015. Targets of the second survey were departments that reported one or more initial patient visits in the first survey. Results In the first survey, 1767 departments responded (response rate: 77.4%). Among them, 161 departments reported one or more initial patient visits. We conducted the second survey among these 161 departments, of which 96 departments responded (response rate: 59.6%). The estimated number of initial visits by patients with congenital limb deficiency was 417 (95% confidence interval: 339–495) per year in 2014 and 2015. The estimated prevalence of congenital limb deficiency in Japan was 4.15 (95% confidence interval: 3.37–4.93) per 10,000 live births. The sex ratio was 1.40. Upper limbs were more affected than lower limbs. Conclusions We revealed the estimated number of initial patient visits per year and birth prevalence of congenital limb deficiency in Japan. Our results will contribute to establishing the disease concept and grades of severity of congenital limb deficiency.

Abstract Purpose To investigate the incidence, etiology, treatment indications, and outcomes regarding infertile male patients in Japan. Methods Between April, 2014 and March, 2015, the authors contacted 47 clinical specialists in male infertility who had been certified by the Japan Society for Reproductive Medicine. The participating clinicians were sent a questionnaire regarding information on their infertile patients, according to etiology and the number and success rates of male infertility operations that had been performed in their practice. Results Thirty‐nine specialists returned the questionnaire and provided information regarding 7268 patients. The etiology of infertility included testicular factors, sexual disorders, and seminal tract obstruction. During the study year, the clinicians performed varicocelectomies, testicular sperm extractions (TESEs), and re‐anastomoses of the seminal tract. The rate of successful varicocelectomies was >70%. The sperm retrieval rates with conventional TESE and microdissection TESE were 98.3% and 34.0%, respectively, while the patency rates with vasovasostomy and epididymovasostomy were 81.8% and 61.0%, respectively. Conclusion Surgical outcomes for infertile male patients are favorable and can be of great clinical benefit for infertile couples. To achieve this, urologists should work in collaboration with gynecological specialists in order to optimize the treatment of both partners.

Objective: The present study aimed to elucidate opinions regarding comprehensibility of audiometry display formats among otolaryngologists in Japan, and to identify the characteristics of otolaryngologists' cognitive processes for audiometry.Methods: We conducted a cross-sectional nationwide questionnaire-based mail survey regarding the comprehensibility of audiometry display formats among 543 Japanese otolaryngologists. Of 543 otolaryngologists to whom the questionnaires were mailed, 137 replied to the questions. For the analysis, the sample size used was 112 participants. The questionnaire contained questions regarding the otolaryngologists' occupational characteristics, and assessed their opinions of four comprehensibility aspects of five display formats.Results: Otolaryngologists in clinics indicated that the passage of time and changes in thresholds of each frequency in numeric tables were ordinary or incomprehensible. More than 60% of otolaryngologists with extensive experience in using electronic medical records indicated that both, the passage of time and change in the thresholds in overlaid thresholds on a chart were comprehensible.Conclusions: Display formats in audiometry influenced the comprehension of pure tone audiometry data. Our results suggest that overlaid thresholds on a chart rather than numeric table or multi-dimensional charts are the primary choice for computerized audiometry display formats in most aspects of audiometry.

Although several pedigrees of familial myelodysplastic syndromes/acute myeloid leukemia (fMDS/AML) have been reported, the epidemiology and clinical features has been poorly understood. To explore the epidemiology of this entity, we performed a retrospective nationwide epidemiological survey in Japan using questionnaire sheets. The questionnaire was sent to 561 institutions or hospitals certified by Japanese Society of Hematology, unearthing the existence of 41 pedigrees of fMDS/AML. Among them, we obtained the clinical information of 31 patients in 20 pedigrees. The median age of the initial diagnosis was 51 years (range 9–88 years) and the WHO classification 2008 ranged from refractory anemia (RA) to AML. Focusing on the familial MDS patients, refractory anemia with excess blasts (RAEB)-2 was the largest group (27.3%). The median overall survival (OS) of fMDS and fAML in this study were 71.6 and 12.4 months, and the five-year OS were 61.3 and 50%, respectively. [ABSTRACT FROM AUTHOR]

Background: Hypertension has remained an imperative risk factor for cardiovascular and cerebrovascular diseases, increasing the national burden of premature deaths over the decades. Purpose: There is limited data on the prevalence of hypertension and its distribution across all geographic regions in India. This nationwide survey was conducted in 2017 to assess the prevalence of hypertension and prehypertension among the Indian adults. Methods: A multilevel stratified cluster sampling technique, with a random selection among the urban and rural populations, was adopted to achieve a sample of 70,031 adults from 24 states and 4 union territories. Blood pressure was measured twice using automated oscillometric machines with a minimum of 3-min gap, and the average was recorded. This was later categorized into prehypertension (elevated blood pressure) and hypertension subgroups as defined by the new 2017 American Heart Association guidelines. Results: The prevalence of prehypertension and hypertension in our study population across all ages was found to be 18.2% and 24%, respectively. Prehypertension was common at a younger age, whereas the prevalence of hypertension was higher in the older age groups. The urban population (24.4%) and males (24.7%) were positively associated with prehypertension and hypertension. The western zone had the highest prevalence of hypertension, whereas the eastern population had the lowest. Conclusion: Our study revealed an alarmingly high prevalence of hypertension, accounting up to one hypertensive in every four adults in India. There is a need for more robust national strategies for identifying and treating hypertension to reduce the national and the global burden of hypertension by 25% before 2025. [ABSTRACT FROM AUTHOR]

Introduction: Considering the increase in the number of patients with diabetes, the quality of diabetes care provided by general practitioners (GP) is critical for preventing complications. We performed a nationwide survey to determine whether the diabetic management provided to patients with type 2 diabetes mellitus (T2DM) by Japanese practitioners is appropriate. Methods: We randomly selected 463 clinics throughout Japan; 8070 patients with T2DM (6525 and 1545 under the care of GP and specialists [SP], respectively) were enrolled. We obtained information on hemoglobin A1c (HbA1c) levels, age, height, body weight, diabetes type and treatment modality, blood pressure (BP), and hypertension or dyslipidemia from each patient. Additionally, we surveyed the collaborations among physicians. Results: The median HbA1c level of patients treated by GP was lower than that of patients treated by SP (6.8 [6.2–7.3], median [interquartile range] vs. 6.9 [6.5–7.5], p < 0.0001). The percentage of patients receiving insulin therapy was also higher (23.8%) among patients treated by SP than among those treated by GP (8.6%). Patients not receiving insulin therapy showed lower median HbA1c levels than those receiving insulin therapy, irrespective of the care provider. The mean body mass index of patients with HbA1c levels < 6.9% or > 9.0% cared for by SP was lower than that of those cared for by GP. The rate of target BP (< 140/90 mmHg) achievement was 73.2% and 73.3% among patients with T2DM and hypertension cared for by GP and SP, respectively. Furthermore, 88.2% of GP reported that consulting with SP was easy. Conclusion: The present study clearly demonstrated that many patients with T2DM are appropriately cared for by general practitioners instead of diabetes specialists in Japan, although the number of diabetes specialists is insufficient to cover all patients with diabetes.

Background: There has been no definitive evidence of chemoradiotherapy being superior to radiotherapy alone in patients aged 80 years or older. The purpose of the present study was to evaluate the results of radiotherapy and chemoradiotherapy in patients aged 80 years or older with esophageal cancer in the Japanese Nationwide Cancer Database. Methods: A total of 358 patients aged 80 years or older who were treated with radiotherapy alone or with chemoradiotherapy for esophageal cancer between 2009 and 2011 were enrolled. Results: The 5-year overall survival (OS) rates in patients with cStages 0–I, II, III and IV were 40.9%, 24.7%, 12.2% and 4.9%, respectively. The 5-year cause-specific survival (CSS) rates in patients aged 80 years or older with cStages 0–I, cStage II, cStage III and cStage IV were 73.5%, 41.4%, 25.3% and 7.4%, respectively. In patients treated with radiotherapy alone, the 5-year OS rates for patients with cStages 0–I, II, III and IV were 36.5%, 12.0%, 5.4% and 0%, respectively. In patients treated with chemoradiotherapy, the 5-year OS rates for patients with cStages 0–I, II, III and IV were 45.0%, 36.1%, 16.4% and 7.1%, respectively. In multivariate analysis, chemoradiotherapy, early stage and squamous cell carcinoma were significantly favorable prognostic factors for OS in patients aged 80 years or older (p < 0.001, p < 0.001 and p = 0.0323, respectively). We were unable to evaluate toxicities, because of lack of information in the registry. Conclusion: Concurrent chemotherapy with radiotherapy for esophageal cancer in patients aged 80 years or older is a significantly favorable prognostic factor for OS. However, chemoradiotherapy should be carefully selected in elderly patients. [ABSTRACT FROM AUTHOR]

Aim: Endometriosis mostly affects the ovary but can also be present outside of the ovary including the pelvic peritoneum, intestine, urinary tract and lung. In case of ovarian endometriotic cyst, an increased risk of ovarian cancer, especially of clear cell and endometrioid histology, has been reported. However, because of the rarity, cancer occurrence from endometriosis at less common sites/rare sites is poorly understood. Methods: We conducted a nationwide survey on the less common/rare site endometriosis in 3539 authorized facilities in Japan. We requested to complete a case report form for each case, including information on the history of endometriosis, treatment for endometriosis, type of surgery, involved site(s) of cancer and endometriosis, histology of cancer, chemotherapy and outcome. Results: Out of 1397 confirmed cases of less common/rare site endometriosis, 11 cases of rare site endometriosis‐associated cancer (RSEAC) were reported: seven of them were associated with intestinal endometriosis, three were associated with urinary tract endometriosis and one was associated with umbilical endometriosis. Interestingly, the histology was endometrioid in seven (64%) cases, and serous, seromucinous borderline, clear cell and mucinous in one case each (10%), differing from the case of ovarian endometriosis‐associated cancer, in which clear cell carcinoma are more common. Conclusion: Our nationwide survey on RSEAC has revealed that: (i) the incidence of malignant transformation may be lower than ovarian endometriosis, (ii) malignant transformation from endometriosis outside the abdominal cavity may be extremely rare and (iii) the histology of RSEAC is predominantly endometrioid type, suggesting an association of a hormonal effect.

Objective(s): Nuclear medicine technologists in Japan often perform additional single-photon emission computed tomography (SPECT) with or without computed tomography (CT) after whole-body imaging for bone scintigraphy. In this study, we wanted to identify the bone scanning protocols used in Japan, together with the current clinical practices. Methods: The study was conducted between October and December 2017. We created a web survey that was hosted by the Japanese Society of Radiological Technology. The questionnaire included 12 items regarding the demographics of the responders, their scan protocols, and the imaging added to, or omitted from, routine protocols. Results: In total, 228 eligible responses were collected from participants with a mean of 11.6±8.4 years' experience in nuclear medicine examination. All responders reported using routine scan protocols that included whole-body imaging. However, only 2%, 4%, 20%, and 14% of the responders also acquired single-field SPECT, singlefield SPECT/CT, multi-field SPECT, and multi-field SPECT/CT, respectively. Conclusion: Our survey results indicate that nuclear medicine practice in Japan is beginning to shift from planar whole-body imaging with additional spot planar images to additional SPECT or SPECT/CT. Further study is required to examine the optimal protocols for bone scintigraphy. [ABSTRACT FROM AUTHOR]

Aims/Introduction: Insulin resistance syndrome (IRS) of type A or B is triggered by gene abnormalities of or autoantibodies to the insulin receptor, respectively. Rabson–Mendenhall/Donohue syndrome is also caused by defects of the insulin receptor gene (INSR), but is more serious than type A IRS. Here, we carried out a nationwide survey of these syndromes in Japan. Materials and Methods: We sent questionnaires to a total of 1,957 academic councilors or responsible individuals at certified facilities of the Japan Diabetes Society, as well as at the department pediatrics or neonatology in medical centers with >300 beds. Results: We received 904 responses with information on 23, 30 and 10 cases of type A or B IRS and Rabson–Mendenhall/Donohue syndrome, respectively. Eight cases with type A IRS‐like clinical features, but without an abnormality of INSR, were tentatively designated type X IRS, with five of these cases testing positive for PIK3R1 mutations. Fasting serum insulin levels at diagnosis (mean ± standard deviation) were 132.0 ± 112.4, 1122.1 ± 3292.5, 2895.5 ± 3181.5 and 145.0 ± 141.4 μU/mL for type A IRS, type B IRS, Rabson–Mendenhall/Donohue syndrome and type X IRS, respectively. Type A and type X IRS, as well as Rabson–Mendenhall/Donohue syndrome were associated with low birthweight. Type B IRS was diagnosed most frequently in older individuals, and was often associated with concurrent autoimmune conditions and hypoglycemia. Conclusions: Information yielded by this first nationwide survey should provide epidemiological insight into these rare conditions and inform better healthcare for affected patients.

Aims: As the number of older people with dementia increases, safe pharmacotherapy in this population has attracted attention in recent years. The aims of this study were to clarify the prescribing patterns in older patients who were prescribed anti-dementia drugs and to investigate the association of potentially inappropriate medications (PIMs) with the use of anti-dementia drugs. Methods: Adults aged ≥65 years, who were prescribed anti-dementia drugs at 585 pharmacies across Japan (N = 7,953), were surveyed. The percentage of prescriptions of anti-dementia drugs and the effect of those prescriptions on PIMs were investigated. Results: Prescriptions of anti-dementia drugs were found in 4.4% of the entire study population. A multiple logistic regression analysis revealed that the use of anti-dementia drugs reduced the risk of prescribing psychotropic drugs, which represented PIMs, and that a combination of anti-dementia drugs (e.g., cholineesterase inhibitor with memantine) may reduce the risk of prescribing PIMs compared with monotherapy. Conclusion: The use of anti-dementia drugs was associated with fewer prescriptions of drugs considered as PIMs. [ABSTRACT FROM AUTHOR]

Context: Better understanding about the attitudes of health-care providers toward end-of-life discussion would facilitate the development of systematic strategies for improving end-of-life care. Objective: To clarify attitudes toward end-of-life discussion with patients near death and explore the factors influencing these attitudes among physicians, nurses, and care staff. Methods: This study was part of a nationwide cross-sectional anonymous survey of the public attitudes toward end-of-life medical care performed in December 2017. The participants were physicians, nurses, and care staff from randomly selected facilities, including hospitals, clinics, home-visit nursing offices, nursing homes, and long-term care facilities throughout Japan. The questionnaire was sent to 4500 physicians, 6000 nurses, and 2000 care staff. We assessed attitudes about end-of-life discussion with patients near death, identification of the proxy decision maker, and sharing documented information on end-of-life discussion with the multidisciplinary team. Results: We analyzed responses from 1012 physicians, 1824 nurses, and 749 care staff. The number of responders who considered they had adequate end-of-life discussion with patients near death was 281 (27.8%), 324 (17.8%), and 139 (18.6%), respectively. Participation in a nationwide education program and caring for at least 1 dying patient per month were factors that showed a significant association with adequate end-of-life discussion and identification of the proxy decision maker. Conclusions: The percentages of physicians, nurses, and care staff involved in adequate end-of-life discussion with patients near death were not high. Participation in a structured education program might have a positive influence on end-of-life discussion with patients. [ABSTRACT FROM AUTHOR]

Background: In definitive chemoradiotherapy (CRTx) for esophageal cancer, a radiotherapy (RT) dose of 50.4 Gy in 28 fractions has been the standard in many countries, while 60 Gy in 30 fractions has been frequently used in Japan. To clarify the optimal RT dose in CRTx for esophageal cancer, we compared clinical outcomes with the two doses using data from the Comprehensive Registry of Esophageal Cancer in Japan by the Japan Esophageal Society (JES). Methods: Of the patients enrolled in the registry for 2015–2017 surveys (patients treated between 2009 and 2011), 996 patients who received definitive CRTx with 50.4 Gy or 60 Gy for thoracic esophageal cancer were eligible for analysis. Results: The complete response (CR) rates in the 50.4 Gy and 60 Gy groups were 49.1% and 46.4%, respectively (p = 0.5851). The 5-year overall survival (OS) rates in the 50.4 Gy group and 60 Gy group for stages I, II/III and IV were 64.2% and 57.2%, 35.0% and 27.0%, and 18.0% and 15.3%, respectively. Since no significant difference was found between the two groups, the 50.4 Gy group was not inferior to the 60 Gy group with regard to OS. Conclusions: The analysis revealed that the 50.4 Gy group had a non-inferior outcome in comparison with the 60 Gy group for stages I, II/III and IV thoracic esophageal cancer. These results were obtained from a large database for the first time in Japan. [ABSTRACT FROM AUTHOR]

Background: A better understanding of differences between the preferences of the general public and the recommendations of healthcare providers with regard to end-of-life (EOL) care may facilitate EOL discussion. Methods: The aim of this study was to clarify differences between preferences of the general public and recommendations of healthcare providers with regard to treatment, EOL care, and life-sustaining treatment (LST) based on a hypothetical scenario involving a patient with advanced cancer. This study comprised exploratory post-hoc analyses of "The Survey of Public Attitude Towards Medical Care at the End of life", which was a population based, cross-sectional anonymous survey in Japan to investigate public attitudes toward medical care at the end of life. Persons living in Japan over 20 years old were randomly selected nationwide. Physicians, nurses, and care staff were recruited at randomly selected facilities throughout Japan. The general public data from the original study was combined to the data of healthcare providers in order to conduct exploratory post-hoc analyses. The preferences of the general public and recommendations of healthcare providers with regard to EOL care and LST was assessed based on the hypothetical scenario of an advanced cancer patient. Results: All returned questionnaires were analyzed: 973 from the general public, 1039 from physicians, 1854 from nurses, and 752 from care staff (response rates of 16.2, 23.1, 30.9, and 37.6%, respectively). The proportion of the general public who wanted "chemotherapy or radiation", "ventilation", and "cardiopulmonary resuscitation" was significantly higher than the frequency of these options being recommended by physicians, nurses, and care staff, but the general public preference for "cardiopulmonary resuscitation" was significantly lower than the frequency of its recommendation by care staff. Conclusion: Regarding a hypothetical scenario for advanced cancer, the general public preferred more aggressive treatment and more frequent LST than that recommended by healthcare providers.

Background: To assess the recent real-world changes in the etiologies of liver cirrhosis (LC) in Japan, we conducted a nationwide survey in the annual meeting of the Japan Society of Hepatology (JSH).Methods: We investigated the etiologies of LC patients accumulated from 68 participants in 79 institutions (N = 48,621). We next assessed changing trends in the etiologies of LC by analyzing cases in which the year of diagnosis was available (N = 45,834). We further evaluated the transition in the real number of newly identified LC patients by assessing data from 36 hospitals with complete datasets for 2008-2016 (N = 18,358).Results: In the overall data, HCV infection (48.2%) was the leading cause of LC in Japan, and HBV infection (11.5%) was the third-most common cause. Regarding the transition in the etiologies of LC, the contribution of viral hepatitis-related LC dropped from 73.4 to 49.7%. Among the non-viral etiologies, alcoholic-related disease (ALD) and nonalcoholic steatohepatitis (NASH)-related LC showed a notable increase (from 13.7 to 24.9% and from 2.0 to 9.1%, respectively). Regarding the real numbers of newly diagnosed patients from 2008 to 2016, the numbers of patients with viral hepatitis-related LC decreased, while the numbers of patients with non-viral LC increased.Conclusions: HCV has remained the main cause of LC in Japan; however, the contribution of viral hepatitis as an etiology of LC is suggested to have been decreasing. In addition, non-viral LC, such as ALD-related LC and NASH-related LC, is suggested to have increased as etiologies of LC in Japan. [ABSTRACT FROM AUTHOR]

Background: The proportion of elderly patients undergoing surgery for gastric cancer is increasing. However, limited number of therapeutic outcomes in the elderly has been reported. Here we examined the surgical results based on a nationwide survey of elderly patients who underwent surgery for Stage I gastric cancer. Methods: Data from 68,353 Stage I patients who underwent gastrectomy between 2001 and 2007 were retrospectively collected. The accumulated data were reviewed and analyzed by the Japanese Gastric Cancer Association registration committee. We first classified the patients as those aged ≤ 74 years and ≥ 75 years. We further classified those patients aged ≥ 75 years into groups by 5-year increments to examine their short- and long-term postoperative outcomes. Results: Patients aged ≥ 75 years accounted for 46.5%. The 30-day mortality rate was < 0.7% for any age group, but for those aged ≥ 75 years, the 60-day and 90-day mortality rates were 0.9–2.3% and 1.2–5.1%, respectively. An examination of long-term survival indicated that, as the class of age increased, the 5-year overall survival (OS) was 47.0–93.1% and disease-specific survival (DSS) was 91.4–98.2%, respectively. Although high DSS rates of ≥ 90% were found for all age groups, OS only accounted for ≤ 82% of patients aged ≥ 75 years. Conclusion: Among elderly patients with Stage I gastric cancer, deaths due to other diseases were frequently observed in the long term. Thus, for elderly patients, it may be appropriate to reconsider the treatment strategy with respect to the balance between the invasiveness of the treatment and the prognosis. [ABSTRACT FROM AUTHOR]

To investigate the effect of guidelines for management of febrile seizures on the clinical practice, we conducted a nationwide survey in Japan. The Japanese guidelines for management of febrile seizures 2015 (GL2015) was released in 2015. In 2016, a questionnaire was sent to all 512 certified hospitals (3 pediatricians each) of the Japan Pediatric Society and all 47 prefecture Pediatric Associations (10 private pediatricians each) in Japan asking about management policies for febrile seizures (FSs) during 2013–2014 and 2016. The questionnaires were about the following procedures: (1) lumbar punctures, blood examinations, and diazepam suppositories for children after a first simple FS at emergency departments; and (2) prophylactic diazepam during febrile illnesses in children with two or three past simple FSs, with no known predictors of recurrence. A total of 1327 pediatricians (66.2%) answered the questionnaire. Numbers of pediatricians performing lumbar punctures and blood examinations, and giving diazepam suppositories after a first simple FS were less in 2016 than in 2013–2014 (1.2% and 2.0%, 53.1% and 61.3%, and 36.7% and 51.9%, respectively). Pediatricians recommending prophylactic diazepam for children with two and three FSs decreased from 45.7% and 82.4% in 2013–2014 to 31.0% and 65.0% in 2016, respectively. GL2015 had an effect on the clinical practices of pediatricians. On the other hand, 65% recommended prophylactic diazepam to children with three simple FSs even though GL2015 did not recommend use of diazepam based on number of previous FS. Anxiety about frequent seizures may affect pediatricians′ clinical practice. [ABSTRACT FROM AUTHOR]

Study Objective: To identify the clinical presentation, diagnostic evaluation, operative or medical management, and postoperative recurrence of umbilical endometriosis.Design: A retrospective national survey.Setting: Obstetrics and Gynecology and Plastic Surgery Departments at a teaching hospital in Japan.Patients: Patients with umbilical endometriosis or malignant transformation.Interventions: A national survey was conducted to identify and evaluate cases of umbilical endometriosis or malignant transformation documented between 2006 and 2016.Measurements and Main Results: The following were evaluated for each patient: age at diagnosis, body mass index, medical history, presence of extragenital endometriosis, surgical history, symptoms, imaging modalities, surgical therapy, hormonal therapy, follow-up period, postoperative recurrence, and time to recurrence. Ninety-six patients were identified with pathologically diagnosed benign umbilical endometriosis. The patients frequently had swelling (86.5%), pain (81.3%), or bleeding (44.8%) in the umbilicus. Sensitivity was 87.1% for physical examination, 76.5% for transabdominal ultrasonography, 75.6% for computed tomography, and 81.8% for magnetic resonance imaging. The cumulative recurrence rate was 1.34% at 6 months, 6.35% at 12 months, and 6.35% at 60 months after surgery. Importantly, there was no recurrence after wide resection including of the peritoneum (0 of 37 cases). The efficacy of dienogest (an oral progestin), gonadotropin-releasing hormone agonists, and oral contraceptives was 91.7%, 81.8%, and 57.1%, respectively. Finally, 2 cases of malignant transformation were identified.Conclusion: There was a low recurrence rate following surgery, and hormonal treatment is an option, although the current findings suggest surgical therapy as the first choice of treatment for umbilical endometriosis.

Background: Although esophagectomy is the standard treatment for resectable esophageal cancer, chemoradiotherapy or radiotherapy alone is also selected for some cases. However, there have been very few detailed studies conducted on a large scale on the efficacy of these treatments in Japan. Methods: Of the patients enrolled in the Comprehensive Registry of Esophageal Cancer in Japan by the Japan Esophageal Society for the 2015–2017 surveys (patients treated between 2009 and 2011), the data of 388 patients treated by definitive radiotherapy alone (RTx) and 1964 patients treated by definitive chemoradiotherapy (CRTx) were analyzed. Results: The median age of the patients was 78 years in the RTx group and 69 years in the CRTx group; thus, the proportion of elderly patients was significantly higher in the RTx group than in the CRTx group (p < 0.0001). With regard to the rates of treatment by the two modalities according to the depth of invasion, extent of lymph node metastasis, and disease stage, the treatment rate by CRTx increased more significantly than that by RTx as the disease progressed (p < 0.0001). With regard to the distribution of the total irradiation dose, 11.4% and 2.3% of patients in the RTx and CRTx groups, respectively, received a dose of 67 Gy or more; thus, the RTx group received significantly higher total irradiation doses (p < 0.0001). In the RTx group, the 5-year overall survival rate was 23.2%, and the rates in patients with cStage 0–I, II, III, and IV disease were 41.8%,18.5%, 9.3%, and 13.9%, respectively. In the patients of the RTx group showing complete response (CR), the 5-year overall survival rate was 46.6% and the rates in patients with cStage 0–I, II, III, and IV disease were 54.8%, 39.6%, 32.4%, and 38.9%, respectively. In the CRTx group, the 5-year overall survival rate was 30.6% and the rates in patients with cStage 0–I, II, III, and IV disease were 57.8%, 47.8%, 23.4%, and 13.0%, respectively. In the patients of the CRTx group showing CR, the 5-year overall survival rate was 59.2% and the rates in patients with cStage 0–I, II, III, and IV disease were 67.9%, 59.5%, 56.5%, and 39.6%, respectively. Conclusion: This study revealed the current status of treatment of esophageal cancer in Japan, and we think that we have been able to establish the grounds for explaining to patients with esophageal cancer and their families the treatment decisions made for them in daily clinical practice.

Background: Almost a quarter century has passed since the first nationwide survey on ulcerative colitis (UC) and Crohn's disease (CD) was conducted in Japan. In this study, we used a nationwide survey to estimate the number of patients and prevalence of these diseases in Japan in 2014.Methods: We conducted a mail-based survey targeting hospitals to estimate the annual numbers of patients with UC and CD in 2014. Respondents were asked to report the numbers of patients who met specific diagnostic criteria for these two conditions. A stratified random sampling method was used, and a total of 3712 departments (internal medicine, surgery, pediatrics, and pediatric surgery) were selected for analysis. The overall and sex-specific annual numbers of UC and CD patients were estimated. The corresponding prevalence rates per 100,000 population were calculated by dividing the number of patients with each disease by the mid-year population of Japan in 2014.Results: The overall survey response rate was 56.7% (2016 departments). The estimated numbers of patients with UC and CD were 219,685 (95% confidence interval: 183,968-255,403) and 70,700 (56,702-84,699), respectively. The annual prevalence rates of UC and CD per 100,000 population were 172.9 (men: 192.3; women: 154.5) and 55.6 (men: 79.5; women: 33.1), respectively. These numbers are almost tenfold increase in comparing the previous survey (22,300 in UC and 7,400 in CD). The male-to-female ratios were 1.24 for UC and 2.40 for CD, and the UC-to-CD ratio was 3.11.Conclusions: The prevalence of UC and CD in Japan has risen substantially over the past two decades, and their disease burden requires further examination.

Background and purpose: A nationwide survey was conducted to understand the epidemiology of cerebral amyloid angiopathy‐related intracerebral hemorrhage (CAA‐related ICH) and cerebral amyloid angiopathy‐related inflammation/vasculitis (CAA‐ri) in Japan. Methods: To estimate the total number and clinical features of patients with CAA‐related ICH and CAA‐ri between January 2012 and December 2014 and to analyze their clinical features, questionnaires were sent to randomly selected hospitals in Japan. Results: In the first survey, 2348 of 4657 departments responded to the questionnaire (response rate 50.4%). The total numbers of reported patients with CAA‐related ICH and CAA‐ri were 1338 and 61, respectively, and their total numbers in Japan were estimated to be 5900 [95% confidence interval (CI) 4800–7100] and 170 (95% CI 110–220), respectively. The crude prevalence rates were 4.64 and 0.13 per 100 000 population, respectively. The clinical information of 474 patients with CAA‐related ICH obtained in the second survey was as follows: (i) the average age of onset was 78.4 years; (ii) the prevalence increased with age; (iii) the disease was common in women; and (iv) hematoma most frequently occurred in the frontal lobe. Sixteen patients with CAA‐ri for whom data were collected in the second survey had the following characteristics: (i) median age of onset was 75 years; (ii) cognitive impairment and headache were the most frequent initial manifestations; and (iii) focal neurological signs, such as motor paresis and visual disturbance, were frequently observed during the clinical course. Conclusions: The numbers of patients with CAA‐related ICH and CAA‐ri in Japan were estimated. [ABSTRACT FROM AUTHOR]

Although the mucosectomy-commencing points on transanal endorectal pull-through (TAEPT) differ among reports, the optimal point is unclear. This study assessed the outcomes among different mucosectomy-commencing points. We conducted a nationwide survey from 2008 to 2012. The data of 1,087 Hirschsprung's disease patients were collected, and data on those who underwent TAEPT were extracted. The patients were divided according to the mucosectomy-commencing points into two groups: in Group A, mucosectomy was started ≥ 5 mm from the dentate line (DL), and in Group B, mucosectomy was started < 5 mm from the DL. The extent of the aganglionic segment and postoperative complications in the month after TAEPT were compared. The data of 327 patients were extracted (Group A, n = 155; B, n = 172). Aganglionosis extending to the sigmoid colon was the most frequent in both groups. Regarding postoperative complications, the patients of each group experienced enterocolitis (Group A: 8.4%; B: 7.6%) and incontinence (A: 3.9%; B: 2.9%). The incidence of rectal mucosal prolapse was significantly greater in Group B (4.1%); (A: 0%, p = 0.02). Although the outcomes of TAEPT were comparable in both groups, rectal mucosal prolapse was significantly frequent in patients in whom the commencing point was < 5 mm from the DL.

Background: Clinical studies on the effects of thalidomide‐induced damage on thalidomide victims as they age have only recently started to be conducted, but no studies have examined socioeconomic differences in terms of healthcare and social status between thalidomiders and the age‐matched general population in Japan. Therefore, we carried out a nationwide survey focusing on the life situations of thalidomiders. Method: Questionnaires were sent to 274 thalidomiders in Japan. The questionnaire items basically matched those of the Comprehensive Survey of Living Conditions (CSLC) in the general population conducted by the Japanese Government. The results were compared with those of the CSLC for individuals aged 55–59 years, which was the cohort most similar in age to the average thalidomider living in Japan. Results: More thalidomiders rated their health condition as relatively bad or bad compared with the general population (20.2% vs. 13.3%, respectively). A much higher percentage of thalidomiders reported having some health or physical problem caused by a disease or injury (68.8% vs. 32.6%, respectively), and thalidomiders reported visiting medical and healthcare‐related facilities more frequently. A higher proportion of thalidomiders (9.2%) were unemployed, and thalidomiders tended to feel higher levels of worry and stress, especially in terms of the future. Conclusions: The results of this nationwide survey of the life situations of thalidomiders in Japan clarified their health conditions and the related associations with socioeconomic status. These findings could be expected to help improve the provision of medical and healthcare, welfare measures, and financial support for thalidomiders in the near future. [ABSTRACT FROM AUTHOR]

Spasmodic dysphonia (SD) is a rare voice disorder caused by involuntary and intermittent spasms of the laryngeal muscles. Both diagnosis and treatment have been controversial. Therefore, a series of clinical studies has recently been conducted in Japan. A nationwide epidemiological survey revealed that adductor SD predominated (90–95% of all cases; 3.5–7.0/100,000), principally among young women in their 20s and 30s. To facilitate early diagnosis, we created diagnostic criteria for SD and a severity grading system. The diagnostic criteria include the principal and accompanying symptoms, clinical findings during phonation, the treatment response, and the differential diagnoses. The severity grade is determined using a combination of subjective and objective assessments. Botulinum toxin (BT) injection is the treatment of choice; however, there have been few high-quality clinical studies and BT has been used off-label. We conducted a placebo-controlled, randomized, double-blinded clinical trial of BT therapy; this was effective and safe. BT treatment is now funded by the Japanese medical insurance scheme. Studies thus far have facilitated early diagnosis and appropriate therapy; they have fostered patient awareness of SD.

Abstract Background Schistosomiasis and soil-transmitted helminthiasis (STHs) are target neglected tropical diseases (NTDs) of preventive chemotherapy, but the control and elimination of these diseases have been impeded due to resource constraints. Few reports have described study protocol to draw on when conducting a nationwide survey. We present a detailed methodological description of the integrated mapping of schistosomiasis and STHs on the basis of our experiences, hoping that this protocol can be applied to future surveys in similar settings. In addition to determining the ecological zones requiring mass drug administration interventions, we aim to provide precise estimates of the prevalence of these diseases. Methods A school–based cross-sectional design will be applied for the nationwide survey across Sudan. The survey is designed to cover all districts in every state. We have divided each district into 3 different ecological zones depending on proximity to bodies of water. We will employ a probability-proportional-to-size sampling method for schools and systematic sampling for student selection to provide adequate data regarding the prevalence for schistosomiasis and STHs in Sudan at the state level. A total of 108,660 students will be selected from 1811 schools across Sudan. After the survey is completed, 391 ecological zones will be mapped out. To carry out the survey, 655 staff members were recruited. The feces and urine samples are microscopically examined by the Kato-Katz method and the sediment smears for helminth eggs respectively. For quality control, a minimum of 10% of the slides will be rechecked by the federal supervisors in each state and also 5% of the smears are validated again within one day by independent supervisors. Discussion This nationwide mapping is expected to generate important epidemiological information and indicators about schistosomiasis and STHs that will be useful for monitoring and evaluating the control program. The mapping data will also be used for overviewing the status and policy formulation and updates to the control strategies. This paper, which describes a feasible and practical study protocol, is to be shared with the global health community, especially those who are planning to perform nationwide mapping of NTDs by feces or urine sampling.

Abstract Background Medical students present higher numbers of physician relatives than expectable from the total population prevalence of physicians. Evidence for such a familial aggregation effect of physicians has emerged in investigations from the Anglo-American, Scandinavian, and German-speaking areas. In particular, past data from Austria suggest a familial aggregation of the medical, as well as of the psychological and psychotherapeutic, professions among medical and psychology undergraduates alike. Here, we extend prior related studies by examining (1) the extent to which familial aggregation effects apply to the whole nation-wide student census of all relevant (eight) public universities in Austria; (2) whether effects are comparable for medical and psychology students; (3) and whether these effects generalize to relatives of three interrelated health professions (medicine, psychology, and psychotherapy). Methods We investigated the familial aggregation of physicians, psychologists, and psychotherapists, based on an entire cohort census of first-year medical and psychology students (n = 881 and 920) in Austria with generalized linear mixed models. Results For both disciplines, we found strong familial aggregation of physicians, psychologists, and psychotherapists. As compared with previous results, directionally opposite time trends within disciplines emerged: familial aggregation of physicians among medical students has decreased, whilst familial aggregation of psychologists among psychology students has increased. Further, there were sex-of-relative effects (i.e., more male than female physician relatives), but no substantial sex-of-student effects (i.e., male and female students overall reported similar numbers of relatives for all three professions of interest). In addition, there were age-benefit effects, i.e., students with a relative in the medical or the psychotherapeutic profession were younger than students without, thus suggesting earlier career decisions. Conclusions The familial aggregation of physicians, psychologists, and psychotherapists is high among medical and psychology undergraduates in Austria. Discussed are implications of these findings (e.g., gender equity, feminization of the medical field, ideas for curricular implementation and student counselling), study limitations, and avenues for future research.

Nana Brochmann,1 Esben Meulengracht Flachs,2 Anne Illemann Christensen,3 Christen Lykkegaard Andersen,1 Knud Juel,3 Hans Carl Hasselbalch,1 Ann-Dorthe Zwisler4 1Department of Hematology, Zealand University Hospital, University of Copenhagen, Roskilde, 2Department of Occupational and Environmental Medicine, Bispebjerg University Hospital, Copenhagen, 3National Institute of Public Health, University of Southern Denmark, Copenhagen, 4Danish Knowledge Centre for Rehabilitation and Palliative Care, University of Southern Denmark and Odense University Hospital, Odense, Denmark Objective: The Department of Hematology, Zealand University Hospital, Denmark, and the National Institute of Public Health, University of Southern Denmark, created the first nationwide, population-based, and the most comprehensive cross-sectional health-related quality of life (HRQoL) survey of patients with myeloproliferative neoplasms (MPNs). In Denmark, all MPN patients are treated in public hospitals and treatments received are free of charge for these patients. Therefore, MPN patients receive the best available treatment to the extent of its suitability for them and if they wish to receive the treatment. The aims of this article are to describe the survey design and the characteristics of respondents and nonrespondents. Material and methods: Individuals with MPN diagnoses registered in the Danish National Patient Register (NPR) were invited to participate. The registers of the Danish Civil Registration System and Statistics Denmark provided information regarding demographics. The survey contained 120 questions: validated patient-reported outcome (PRO) questionnaires and additional questions addressing lifestyle. Results: A total of 4,704 individuals were registered with MPN diagnoses in the NPR of whom 4,236 were eligible for participation and 2,613 (62%) responded. Overall, the respondents covered the broad spectrum of MPN patients, but patients 70–79 years old, living with someone, of a Danish/Western ethnicity, and with a higher level of education exhibited the highest response rate. Conclusion: A nationwide, population-based, and comprehensive HRQoL survey of MPN patients in Denmark was undertaken (MPNhealthSurvey). We believe that the respondents broadly represent the MPN population in Denmark. However, the differences between respondents and nonrespondents have to be taken into consideration when examining PROs from the respondents. The results of the investigation of the respondents’ HRQoL in this survey will follow in future articles.

Introduction: For more than two decades, integrated care initiatives have been considered and implemented throughout Europe and North America to overcome challenges linked to chronic disease care in communities [1, 2]. These initiatives aim at reorganizing healthcare systems and services to foster care continuity, coordination and integration. Amongst other authors, Suter and collaborators state that the involvement of “interprofessional teams [3]” is a key element to such models of care. Nevertheless, the benefits of interprofessional collaboration (IPC) remain unclear in published literature, and results arising from IPC in integrated care initiatives are scarce [4]. Our study had two aims: First, to explore whether IPC in integrated care initiatives was associated with reported improvements at the organizational level and at patient care level. Second, to assess whether existing barriers to the implementation of integrated care initiatives moderated those associations. Methods: We used self-reported data from the Swiss Integrated Care Survey [5], a cross-sectional study that identified and described all Swiss integrated care initiatives meeting four eligibility criteria (i.e. using some type of formalization, considering >2 different groups of healthcare professionals, integrating >2 healthcare levels, and was ongoing at data collection time). Moderated mediation analyses were conducted by using perceived care improvement as outcome, IPC implementation as independent variable, perceived organizational improvement as mediator, and professional, patient and financial barriers (i.e. inadequate initiative funding and inadequate patient reimbursement) as moderators. Results: 153 representatives of the initiatives identified in the Swiss Integrated Care Survey returned a valid questionnaire (response rate 92.7%).Analyses showed that IPC implementation was associated with perceived improvements at the organizational level, which in turn was associated with perceived improvements in patient care. However, the positive association between IPC implementation and perceived improvements at the organizational level no longer existed when financial barriers to funding initiatives or to patients’ reimbursement were reported. Discussion. According to the representatives of integrated care initiatives,financial barriers were the most deleterious ones influencing the positive impact of IPC on integrated care functioning. Conclusion: Lessons learned: To our knowledge, this study is the first to investigate the role of financial barriers in IPC implementation within integrated care initiatives. The implementation of IPC in practice, which may reduce long-term costs of integrated care initiatives [6], requires initial financial resources. This forefront investment is crucial since the success of integrated care initiatives including IPC depend on it [3]. Limitations: The cross-sectional design of the study limits causal inferences; and only representatives of initiatives were contacted. Suggestion for future research: Future research should include a follow-up of integrated care initiatives to assess longer-term effects of IPC and financial barriers on the effectiveness of these initiatives.

Adult T-cell leukemia/lymphoma (ATL) is a rare and aggressive T-cell malignancy with a high mortality rate, resulting in a lack of information among ophthalmologists. Here, we investigated the state of ophthalmic medical care for ATL and ATL-related ocular manifestations by conducting the first large-scale nationwide survey in Japan. A total of 115 facilities were surveyed, including all university hospitals in Japan that were members of the Japanese Ophthalmological Society and regional core facilities that were members of the Japanese Ocular Inflammation Society. The collected nationwide data on the state of medical care for ATL-related ocular manifestations and ATL-associated ocular findings were categorized, tallied, and analyzed. Of the 115 facilities, 69 (60%) responded. Overall, 28 facilities (43.0%) had experience in providing ophthalmic care to ATL patients. ATL-related ocular manifestations were most commonly diagnosed “based on blood tests and characteristic ophthalmic findings.” By analyzing the 48 reported cases of ATL-related ocular manifestations, common ATL-related ocular lesions were intraocular infiltration (22 cases, 45.8%) and opportunistic infections (19 cases, 39.6%). All cases of opportunistic infection were cytomegalovirus retinitis. Dry eye (3 cases, 6.3%), scleritis (2 cases, 4.2%), uveitis (1 case, 2.1%), and anemic retinopathy (1 case, 2.1%) were also seen. In conclusion, intraocular infiltration and cytomegalovirus retinitis are common among ATL patients, and ophthalmologists should keep these findings in mind in their practice.

Background: Human milk (HM) has been proven to provide immunological and nutritional advantages to neonates; however, acquired cytomegalovirus (CMV) infection can be associated with raw HM. In Japan, there are no standardized guidelines concerning HM handling. This cross-sectional survey was performed to reveal specific trends in HM handling in neonatal intensive care units (NICUs) in Japan., Methods: A questionnaire was sent to 255 NICUs participating in the Japanese Neonatologist Association in May 2020. It involved HM handling practices, such as maternal screening, pasteurization, storage, and the workforce., Results: Of 255 NICUs, 174 (67.8%) responded to the survey. Maternal CMV screening was carried out in 37 units (22.2%), and CMV inactivation in HM was performed in 44 units (26.5%). For CMV inactivation, a freeze-thawing method was employed in about 90% of units. In 70% of units providing CMV inactivation, CMV inactivation was conducted regardless of bodyweight and corrected gestational age of infants until the infants' discharge. Acquired CMV infection in preterm neonates was observed in 43 units (25.7%) in the survey period., Conclusion: A wide range of HM handling practices are used in Japanese NICUs. A national guideline for handling HM in NICUs should be created to promote the infection control of CMV., (© 2024 Japan Pediatric Society.)

Introduction: We aimed to evaluate the safety and short-term outcomes of robotic-assisted transabdominal preperitoneal repair for inguinal hernia in 12 pioneering hospitals in Japan., Methods: Clinical data of patients who underwent robotic-assisted transabdominal preperitoneal repair between September 1, 2016, and December 31, 2021 were collected. Primary outcome measures were intra-operative adverse events and post-operative complications, whereas secondary outcomes were surgical outcomes, including chronic pain, recurrence, and learning curve., Results: In total, 307 patients were included. One case of inferior epigastric arterial injury was reported; no cases of bowel or bladder injury were reported. Thirty-five seromas were observed, including four (1.3%) cases that required aspiration. The median operative time of a unilateral case was 108 minutes (interquartile range: 89.8-125.5), and post-operative pain was rated 1 (interquartile range: 0-2) on the numerical rating scale. In complicated cases, such as recurrent inguinal hernias and robotic-assisted radical prostatectomy-associated hernias, dissection and suture were safely achieved, and no complications were observed, except for non-symptomatic seroma. All patients underwent robotic procedures, and there was no chronic post-operative inguinal pain, although one case of hernia recurrence was reported. Regarding the learning curve, plateau performance was achieved after 7-10 cases in terms of operative time (P < .001)., Conclusion: Robotic-assisted transabdominal preperitoneal repair can be safely introduced in Japan. Regardless of the involvement of many surgeons, the mastery of robotic techniques was achieved relatively quickly. The advantage of robotic technology such as wristed instruments may expand the application of minimally invasive hernia repair for complicated cases., (© 2023 Asia Endosurgery Task Force and Japan Society of Endoscopic Surgery and John Wiley & Sons Australia, Ltd.)

In Japan, the Pharmaceutical and Medical Device Act was amended in December 2019, and now requires pharmacists to follow-up on patients during treatment. Although there have been some studies on the effectiveness of follow-ups by pharmacists, there are no reports on the status of implementation in clinical practice. We conducted a nationwide survey on follow-up care to investigate the actual situation. We randomly selected 10% of community pharmacies in each prefecture and conducted a survey. We built a web-based system for the collection of basic information on the pharmacies and follow-up cases. A total of 561 pharmacies were pre-entered. Of these, 110 pharmacies (19.6%) reported 326 follow-up cases. Information was provided to doctors in 129 cases (39.6%), of which prescription proposals were made in 10 (7.8%) instances. The follow-up implementation rate based on the number of prescriptions dispensed was estimated to be 0.84% (95% confidence interval: 0.76-0.94%). This study revealed the status of follow-ups in clinical practice. Pharmacists can contribute to the optimization of drug treatment by providing follow-up information to doctors and making prescription proposals.

Introduction: Acute stroke rehabilitation is crucial for achieving good functional recovery, even during the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to clarify the impact of the COVID-19 pandemic on acute stroke rehabilitation and identify which components in the acute stroke rehabilitation provision system were susceptible to the pandemic., Methods: A web-based questionnaire survey was conducted in all primary stroke centers (PSCs) in Japan between February 7 and April 21, 2022. The survey included questions about the current status of acute stroke rehabilitation and the influence of the pandemic. We classified the influences and investigated the relationship between the influence of the pandemic and the provision of rehabilitation. Additionally, we investigated a group of prefectures divided according to the grade of the pandemic., Results: The survey response rate was 67% (639 of 959 PSCs). Among them, 387 PSCs (61%) reported that the COVID-19 pandemic affected acute stroke rehabilitation. In PSCs affected by the pandemic, more rehabilitation-related staff were working, and the proportion of weekend/holiday rehabilitation implementation was higher compared to those unaffected. In PSCs from highly infected prefectures, no significant relationship was observed between the influence of the pandemic and the rehabilitation provision system., Conclusions: PSCs that provide denser acute stroke rehabilitation may be affected to a greater extent by the pandemic. We conclude that stroke hospitals should formulate infection control procedures for acute stroke rehabilitation in advance, depending on the conditions of the region and facility., (© 2024 S.

Introduction: Many guidelines now recommend early rehabilitation for acute stroke patients. However, evidence remains lacking regarding the specific timings for initiation of various rehabilitation steps and management when complications are encountered in acute stroke rehabilitation. This survey aimed to investigate actual clinical situations in acute stroke rehabilitation in Japan and to improve the medical systems for rehabilitation and plan further studies., Methods: This nationwide, cross-sectional, web-based questionnaire survey was administered between February 7, 2022, and April 21, 2022, targeting all primary stroke centers (PSCs) in Japan. Among several components of the survey, this paper focused on the timing of the initiation of three rehabilitation steps (passive bed exercise; head elevation; and out-of-bed mobilization), along with the management of rehabilitation (continued or suspended) in the event of complications during acute stroke rehabilitation. We also investigated the influence of facility features on these contents., Results: Responses were obtained from 639 of the 959 PSCs surveyed (response rate: 66.6%). In cases of ischemic stroke and intracerebral hemorrhage, most PSCs initiated passive bed exercise on day 1, head elevation on day 1, and out-of-bed mobilization on day 2 (with day of admission defined as day 1). In cases with subarachnoid hemorrhage, rehabilitation steps were delayed compared to other stroke subtypes or showed wide variation depending on the facility. Passive bed exercise was accelerated by the presence of protocols for rehabilitation and weekend rehabilitation. Out-of-bed mobilization was accelerated by the presence of a stroke care unit. Facilities with board-certified rehabilitation doctors were cautious regarding the initiation of head elevation. Most PSCs suspended rehabilitation training in the event of symptomatic systemic/neurological complications., Conclusion: Our survey revealed the actual situation of acute stroke rehabilitation in Japan and indicated that some facility features appear to influence early increases in physical activity levels and early mobilization. Our survey provides fundamental data to improve the medical systems for acute stroke rehabilitation in the future., (© 2023 S. Karger AG, Basel.)

Reintroducing apex predators is an important approach in ecosystem restoration; however, it is challenging. Wolves (Canis lupus) were exterminated in Japan around 1900, and since then, there has been a lack of top predators throughout the country. Currently, the wild ungulate population is increasing, causing agricultural and forest damage. This has triggered an ongoing debate among researchers and nongovernmental organizations on whether wolves should be reintroduced to promote self-regulating biodiverse ecosystems. We conducted a nationwide survey to examine public attitudes toward wolf reintroduction (WR) in Japan. We sent online questionnaires to 88,318 citizens across the country. Among the 12,028 respondents, excluding those with invalid or incomplete answers and unqualified respondents, we obtained and analyzed 7500 responses that were representative of Japanese citizens in terms of some key sociodemographic attributes. More respondents disagreed with WR (39.9%) than agreed (17.1%), and many respondents (43.0%) were undecided. Structural equation modeling revealed that risk perceptions affected public attitudes, implying that the greater the perceived threat of wolf attacks, the less likely people are to support WR. In contrast, attitudes toward wolves (e.g., "I like wolves.") influenced by wildlife value orientation and beliefs about the ecological role of wolves (e.g., controlling deer populations) positively affected public attitudes toward WR. Those who had a positive attitude toward WR showed intentions to engage in behaviors that support WR. Our results suggest that the dissemination of information related to the ecological role of wolves and the development of a more mutualistic mindset in people could positively influence public support for WR in Japan., (© 2023 The Authors.

Objectives: This study aimed to investigate the performance of oral assessment and health care education at nursing schools across Japan to identify problems and the need for oral health professional support., Methods: The participants were the academic staff in charge of oral health care education in the basic, adult, gerontological, and home nursing fields of 295 schools in Japan that offered a bachelor's degree in nursing. A questionnaire was sent to 1180 heads of the nursing fields of these schools. They were requested to have oral health care educators complete the survey; data on the performance of oral assessment and health care education and human resources allocated were collected through a questionnaire., Results: A total of 311 (26%) questionnaires were returned, 196 (63%) of which were completed by oral health care educators. Regarding the performance of oral assessment education, the majority (71%) of them spent less than 2 hours in teaching, and only 24.5% taught the usage of oral assessment tools. Regarding the performance of oral health care education, more than 90% spent less than 2 hours in lecture-based and practical oral health care education, respectively. Less than half taught the association of periodontal diseases with diabetes and cardiovascular diseases and use of fluoride for caries prevention in the lectures, and only approximately 30% taught the usage of an interspace brush or dental floss. Moreover, less than 10% of oral health professionals taught oral health care in lectures or practical oral health care., Conclusions: This study revealed problems associated with oral assessment and health care education in Japanese nursing schools. To address these, support from oral health care professionals is required. Further studies are also required to reveal problems in oral assessment and health care education in other nursing schools that do not offer a bachelor's degree programme in Japan and other countries., Competing Interests: Conflict of interest None disclosed., (Copyright © 2022 The Authors.

Background: Internet addiction (IA) has been drawing attention to mental health. However, few reports have been found on the related factors of at-risk IA among regular workers by a nationwide survey. The study aimed to evaluate the characteristics of at-risk IA and identify related factors among senior high school teachers in Japan., Methods: This survey was a cross-sectional survey of high schools across Japan in 2017. There were 3189 teachers (2088 males and 1098 female) who participated in this survey. The questionnaire asked about their devices, both the time and the activities of using their internet, and sociodemographic factors. IA was measured by the internet addiction test (IAT) by which 40-79 points were classified as at-risk IA, and more as IA. We compared the related factors of at-risk IA and non-IA using descriptive analysis and multivariable regression analysis., Results: The rates of IA and at-risk IA were 0.09% (n = 3) and 6.91% (n = 220), respectively. At-risk IA was positively associated with activities on the internet for gaming, entertainment, net-surfing, and younger ages. In addition, the at-risk IA group had a longer time spent on the internet than the non-IA group., Conclusions: Around 7% of high school teachers are at-risk IA in this survey, though they have regular work. Our results suggest that at-risk IA may be reinforced not only by the active internet use such as gaming, but also by purposeless behaviors, such as net-surfing. Managing time on the internet may support preventing at-risk IA among senior high school teachers., (© 2023 The Authors.

Aim: The aim of this study was to investigate epidemiological and clinical aspects of severe postpartum hemorrhage (PPH) in Japan. Methods: We used national health insurance claims from 2011 to 2014 provided by the Ministry of Health, Labour and Welfare. The data included randomly selected claims that covered 10% of all inpatients in October, a so-called sampling dataset (covering 1/120 inpatients per year). We extracted claims for transfused blood, and further narrowed down the claims by names of diseases linked to PPH. As most referral obstetric facilities have adopted the diagnosis procedure combination (DPC)-based payment system while small-scale obstetric facilities have not (non-DPC facilities), the claims were also analyzed separately for DPC and non-DPC facilities. We assessed the incidence and causes of PPH, transfusion volume of red blood cells (RBC) and fresh frozen plasma (FFP), and surgical hemostatic management. Results: The number of PPH cases that required blood transfusion in the sampling dataset was 29, 29, 32, and 36 in 2011, 2012, 2013, and 2014, respectively. The leading cause of PPH was uterine atony followed by placental abruption. Although no specific trends were observed for the volume of transfused RBC (1467 ± 234 ml in 2014), there was a steady increase in the rate of FFP utilization in non-DPC facilities from 37% to 79% over the 4-year sampling period. Intrauterine balloon tamponade emerged in 2014. Conclusion: This nationwide survey indicates that the annual incidence of severe PPH is increasing. Furthermore, FFP has become more prevalent in small-scale obstetric facilities. [ABSTRACT FROM AUTHOR]

Patient safety is a major healthcare challenge. Due to a lack of safety culture knowledge among dental professionals, our objectives were to measure the level of patient safety culture using the Safety Attitude Questionnaire in Chinese (SAQ-C) and identify factors associated with positive attitudes toward patient safety. A nationwide cross-sectional survey was conducted within dentistry departments of 20 hospitals and in 40 dental clinics, from which were randomly chosen. The survey (SAQ-C) comprised of 32 items and reflects five dimensions of patient safety culture. The second section collects demographic information that supposedly affects attitudes toward patient safety. Logistic regression analyses were used to identify factors that supposedly influenced positive attitudes toward patient safety. Mean SAQ-C scores were significantly higher in respondents who were male, older, dentists, supervisors, and working in clinics. Positive attitudes toward patient safety were found in 172 participants (55.7%). Multivariate analyses revealed age and place of work are significantly associated with positive safety attitudes. A limitation of this study is that the association between SAQ-C scores and patient outcomes could not be examined. With a lack of research in the dental field, our study provides important information on patient safety attitudes for dental healthcare workers. Results from this study present the current status of patient safety culture and help raise awareness of it. Most notably, the study identified several factors associated with positive attitudes toward patient safety. The information can be used to improve patient safety in the future.

In recent years, environmental issues emerging from per- and polyfluoroalkyl substances (PFAS) have raised high concern worldwide. Levels of human exposure to PFAS remain unknown in India. Biomonitoring data obtained from hair analysis have been evidenced to provide insight into retrospective human exposure to PFAS. In this study, 25 PFAS, including perfluoroalkyl acids and their precursors, were measured in 39 human hair samples collected from 14 cities in India. The inuflence of gender on the PFAS levels was also examined. To our knowledge, this is the first attempt to provide preliminary indicative data (due to the limited sample size and variability in hair-length sampling) on the levels of PFAS in Indian hair. The concentrations of total PFAS in hair varied from below matrix-specific limit of quantification (<0.02 ng/g) to 3.78 ng/g. Among 9 PFAS quantified, perfluorohexanesulfonic acid (PFHxS), perfluorooctanesulfonic acid (PFOS), and perfluorooctanoic acid (PFOA) were the predominant compounds. Categorized into 4 regions, PFAS contamination exhibited certain regional difference where South India may show higher levels than the other regions. Highly significant positive correlation was observed between PFHxS and PFOS (p ≪ 0.001; r = 0.644), suggesting similar pathways of exposure to the two compounds. Higher PFAS occurrence was generally observed in the hair of females. Our results highlighted the urgent need to investigate the deposition mechanism of PFAS in hair. Image 1 • This is the first nationwide biomonitoring of PFAS in Indians. • PFHxS, PFOS, and PFOA were predominant in hair samples collected in India. • N -EtFOSA and 6:2 FTUCA were firstly detected in human hair samples. • Regional difference in PFAS levels was found in Indian hair. • Gender might influence PFAS accumulation in hair.

Background: Fetal surgery for myelomeningocele (MMC) has yet not been performed in Japan, and the clinical background of fetal MMC in Japan remains poorly described. We examined the prenatal characteristics and perinatal outcomes of fetal MMC to prepare for the introduction of fetal surgery. Methods: A nationwide questionnaire survey was conducted with regard to fetuses with MMC between January 2012 and December 2014 at perinatal centers in Japan. Results: In 50 tertiary centers, 188 cases of MMC were identified, of which 126 (67%) were isolated cases. Only half of the cases involved referral to tertiary centers with a diagnosis of MMC. The median time point for a prenatal diagnosis was 26 weeks' gestation (range, 12–38 weeks); in 54% of cases the diagnosis occurred after 26 gestational weeks, which is over the limit for fetal surgery for MMC. Furthermore, in 22% of cases the diagnosis was made before 22 gestational weeks, and in three‐quarters of these cases termination of pregnancy was selected. No fetal or neonatal deaths were observed in the isolated MMC group. MMC repair, ventriculoperitoneal shunt and clean intermittent catheterization were required after birth in 100%, 73% and 55% of isolated MMC cases, respectively. In total, 96% of the tertiary centers cared for <5 cases of fetal MMC per year. Conclusions: Gestational age at MMC diagnosis was late mid‐gestation, therefore earlier detection is essential when considering fetal treatment of MMC in Japan. Although the survival rate was excellent, in three‐quarters of isolated MMC cases ventriculoperitoneal shunt was required. Early detection and centralization of MMC cases at specialized centers should be considered. [ABSTRACT FROM AUTHOR]

Objective: This study was undertaken to determine the characteristics of congenital cholesteatoma (CC) in Japan, via a nationwide survey using staging and classification criteria for middle ear cholesteatoma, as proposed by the Japan Otological Society (JOS).Methods: A nationwide survey regarding middle ear cholesteatoma treated in 2015 was performed. There were 1787 registrations from 74 facilities, among which, CC accounted for 12.9% (231 cases) of all middle ear cholesteatoma cases. The extent of the disease was classified according to the classification and staging of cholesteatoma proposed by JOS in 2015.Results: The age of the patients ranged from 1 to 55 years (mean, 8.2 years; median, 6 years; 149 ears of males; 82 ears of females). Among these cases, 105 (45.5%) were classified as stage I, 121 (52.4%) as stage II, and 5 (2.1%) as stage III, with no cases in stage IV. In the sub classification of stage I, 35 (33%), 43 (41%) and 27 (26%) ears were classified as stages I-a, I-b and I-c, respectively. Stage I-b (cholesteatoma confined to the posterior half of the tympanic cavity) was more frequent than stage I-a (the anterior half of tympanic cavity). Pre-operative hearing level of air-conduction was 20.5dB for stage I-a, 34.5dB for stage I-b, 30.5dB for stage I-c, 38.6dB for stage II, and 59.0dB for stage III. The rate of missing stapes superstructure increased as the disease progressed. In the same way, the mastoid development lowered as the stage of the disease progressed. There were significant differences in the age at operation, pre-operative hearing level, status of stapes, and major ossiculoplasty, between stage l-a and l-b.Conclusions: The current condition of CC in Japan was been evaluated; in particular, it was observed that the cases limited to the posterior part of tympanic cavity were not rare. The JOS stage classification based on the progression of the disease seemed simple and efficient. [ABSTRACT FROM AUTHOR]

Enteral feeding is critical for postnatal growth of very low birthweight infants (VLBWI); however, a standard feeding strategy has not been established in Japan. A 2- or 3-h feeding interval is generally used, but no clear evidence supports either approach. Additionally, there is no nationwide breast milk bank in Japan and no consensus exists on the use of donor breast milk (DBM). To clarify the current feeding strategies for VLBWI in Japan, we undertook a nationwide survey. We sent a questionnaire to the 382 NICUs included in the Neonatal Research Network in Japan. We sought information on NICU size, number of admissions, necrotizing enterocolitis (NEC) incidence, feeding interval, and use of DBM. We received responses from 217 NICUs (56.8%), including 76 tertiary centers and 140 regional centers. We only analyzed data obtained from tertiary perinatal centers with a high response rate (77.6%) owing to the insufficient response rate of lower-level facilities (<50%). Most NICUs (71.1%) used a 3-h feeding interval. Only 9.2% used a 2-h interval for all VLBWI. Most NICUs (64.5%) never used DBM, which is not routinely pasteurized. DBM was used in 27 NICUs (35.5%), with and without limitations. Data from 14,233 VLBWI were analyzed; 258 infants (1.8%) were diagnosed with NEC from 2011 to 2015. The incidence of NEC was higher in NICUs that used a 2-h interval (2.7%) than in others. No association was found between NEC and the use of DBM. The NEC incidence did not differ between centers using the most common strategy of a 3-h interval without DBM and those using other strategies. Most NICUs in Japan use a 3-h feeding interval and do not use DBM for VLBWI. Further prospective studies including multiple confounders are required to clarify the relationship between feeding strategy and the incidence of NEC. [ABSTRACT FROM AUTHOR]

Highlights • Omega-3 index in the Czech population is low. • There is no difference between urban and rural areas. • Higher intake of omega-3 PUFA is suggested. Abstract Naturally occurring long-chain omega-3 PUFA such as eicosapentaenoic acid (EPA; 20:5 ω-3) and docosahexaenoic acid (DHA; 22:6 ω-3) exert multiple effects on health, which are related to the intake of these lipids in the diet and correlate with the levels of omega-3 PUFA in the body. These levels are reflected by the omega-3 PUFA index, i.e. the EPA and DHA content as % of all fatty acids in red blood cells. The aim of this study was to evaluate omega-3 index in the Czech Republic, using blood samples collected from the capital city (n = 476) and the rural region (n = 388). The mean omega-3 index was 3.56 mol % with a maximal value of 8.10% and a minimal value of 1.12%. There was no difference in the index value between rural and urban / industrial regions, but this value was higher in subjects who reported eating fish or omega-3 PUFA supplements. In conclusion, the results indicated suboptimal values of the omega-3 index in the Czech population independent of the sampling region. [ABSTRACT FROM AUTHOR]
