RESUMEN
BACKGROUND: Restless legs syndrome (RLS) is a neurological disorder that causes unpleasant symptoms in the legs when resting, which are relieved by movement. Pharmacotherapy is the standard treatment. However, current treatment provides only symptomatic relief and may result in adverse effects with long-term use. Treatment protocols using herbal medicines have emerged to compensate for this limitation. CASE PRESENTATION: A 70-year-old Asian woman visited our hospital with worsening headaches that had persisted for 30 years. Her headaches were aggravated by night-time lower-extremity discomfort. The patient was diagnosed with RLS based on the 2012 Revised International Restless Leg Syndrome Study Group Diagnostic Criteria (IRIS). The patient was prescribed herbal medicines, Shihogyeji-tang, Gyejibokryeong-hwan, and Jakyakgamcho-tang, all of which contain Paeoniae Radix. Fourteen days after starting herbal medicine treatment, the IRIS score decreased from 30 to 18. The patient experienced less leg discomfort. Moreover, her sleep time increased, and her headaches resolved. After 28 days of herbal treatment, the IRIS score decreased to 9. Importantly, the patient reported no sleep disturbance or headaches. Subsequently, conventional medications were discontinued. The patient remained stable (IRIS score: 9-10). Herbal treatment was discontinued on day 163. At the last follow-up, (day 364), the patient has not reported any symptom recurrence. CONCLUSIONS: We described a female patient with a 30-year history of RLS symptoms and related sleep disturbances that induced chronic uncontrolled headaches, who experienced improvements shortly after using herbal medicines containing Paeoniae Radix. Conventional medications were discontinued and the patient had no recurrence of symptoms. Considering these, herbal medicines containing Paeoniae Radix may be a suitable alternative treatment for RLS and its related symptoms.
RESUMEN
BACKGROUND: Functional gastrointestinal disorders (FGIDs), including functional dyspepsia (FD) and irritable bowel syndrome (IBS), are characterized by chronic and recurrent gastrointestinal symptoms. Clinically, FD and IBS often resemble gastrointestinal dysmotility caused by autoimmune autonomic neuropathy. We examined the seropositive frequency of autoantibodies against ganglionic nicotinic acetylcholine receptors (gnAChRs) in patients presenting with FGIDs. OBJECTIVE: To elucidate the seropositivity of gnAChR antibodies and the clinical features of seropositive FD and IBS. MATERIALS AND METHODS: We measured autoantibodies against the gnAChR α3 and ß4subunits using luciferase immunoprecipitation systems. Serum samples from patients with any autonomic symptoms were obtained from hospitals in Japan between January 2012 and August 2018 (1787 serum samples of 1381 patients). We selected FD and IBS patients and compared the clinical characteristics and prevalence of autonomic symptoms between those with seropositive and seronegative IBS and FD. RESULTS: Nine IBS and two FD cases (one comorbid case with IBS) were found. We found four patients (36.4%) in whom gnAChR antibodies were positive in these eleven patients. Sicca symptoms were observed in three of four cases (75%) of seropositive FGID compared with zero of seven cases (0%) of seronegative FGID. CONCLUSIONS: We found patients with gnAChR antibodies in FD and IBS patients. These data will be valuable for elucidating the pathophysiology of these FGIDs and developing new treatment strategies.
RESUMEN
INTRODUCTION: With an aging global population posing healthcare challenges, especially in community healthcare, training professionals for community healthcare remains a global educational challenge, including in Japan. While previous research shows increased student interest in community healthcare through practical experiences, the focus has primarily been on rural areas, leaving a gap in understanding urban-based community medical education. This study aimed to evaluate the impact of urban community-based medical education on students' understanding and attitudes toward community healthcare. METHODS: This study was conducted at Kyushu University in Fukuoka City, the sixth-largest city in Japan. For fifth-grade medical students, a community-based medical education program is mandatory, with a one-week schedule that includes orientation, one day in a clinic, and three days in a community hospital. The program aimed to expose students to various healthcare settings, emphasizing outpatient care, inpatient management, home health care, home nursing, and rehabilitation. A self-administered questionnaire referencing the Model Core Curriculum for medical education was administered immediately before and after the program, and the differences in students' perceptions were assessed using the Student's t-test. RESULTS: Findings from 188 students completing both pre- and post-program questionnaires revealed significant improvements in perceptions of students' knowledge and skills related to community healthcare. After the training, there was a noteworthy positive shift in attitudes toward community healthcare and increased interest in primary care physicians as a career choice. Although students maintained a preference for urban areas, there was a notable inclination towards rural settings. The study highlights the program's success in enhancing students' understanding and positive attitudes toward community healthcare within an urban context. It challenges prior notions regarding work-life balance and urban-rural preferences in career choices. CONCLUSIONS: Urban community-based medical education significantly improved students' perceptions and attitudes toward community healthcare. It offers valuable insights for curriculum planners, emphasizing the need for continued research into sustained effects and broader applicability.
RESUMEN
Background: Alzheimer's disease (AD), the most prevalent form of dementia, is a debilitating, progressive neurodegeneration. Amino acids play a wide variety of physiological and pathophysiological roles in the nervous system, and their levels and disorders related to their synthesis have been related to cognitive impairment, the core feature of AD. Our previous multicenter trial showed that hachimijiogan (HJG), a traditional Japanese herbal medicine (Kampo), has an adjuvant effect for Acetylcholine estelase inhibitors (AChEIs) and that it delays the deterioration of the cognitive dysfunction of female patients with mild AD. However, there are aspects of the molecular mechanism(s) by which HJG improves cognitive dysfunction that remain unclear. Objectives: To elucidate through metabolomic analysis the mechanism(s) of HJG for mild AD based on changes in plasma metabolites. Methods: Sixty-seven patients with mild AD were randomly assigned to either an HJG group taking HJG extract 7.5 g/day in addition to AChEI or to a control group treated only with AChEI (HJG:33, Control:34). Blood samples were collected before, 3 months, and 6 months after the first drug administration. Comprehensive metabolomic analyses of plasma samples were done by optimized LC-MS/MS and GC-MS/MS methods. The web-based software MetaboAnalyst 5.0 was used for partial least square-discriminant analysis (PLS-DA) to visualize and compare the dynamics of changes in the concentrations of the identified metabolites. Results: The VIP (Variable Importance in Projection) score of the PLS-DA analysis of female participants revealed a significantly higher increase in plasma metabolite levels after HJG administration for 6 months than was seen in the control group. In univariate analysis, the aspartic acid level of female participants showed a significantly higher increase from baseline after HJG administration for 6 months when compared with the control group. Conclusion: Aspartic acid was a major contributor to the difference between the female HJG and control group participants of this study. Several metabolites were shown to be related to the mechanism of HJG effectiveness for mild AD.
RESUMEN
Objective Patients in whom coronavirus disease 2019 (COVID-19) was suspected or confirmed between January 1, 2020, and October 31, 2021, were enrolled from Japanese hospitals in this multicenter, retrospective, observational study. Methods Data on the treatment administered (including conventional and Kampo medicine) and changes in common cold-like symptoms (such as fever, cough, sputum, dyspnea, fatigue, and diarrhea) were collected from their medical records. The primary outcome was the number of days without a fever (with a body temperature <37°C). The secondary outcomes were symptomatic relief and the worsening of illness, defined as the presence of a condition requiring oxygen inhalation. The outcomes of patients treated with and without Kampo medicine were compared. Patients We enrolled 962 patients, among whom 528 received conventional and Kampo treatment (Kampo group) and 434 received conventional treatment (non-Kampo group). Results Overall, after adjusting for the staging of COVID-19 and risk factors, there were no significant between-group differences in the symptoms or number of days being afebrile. After performing propensity score matching and restricting the included cases to those with confirmed COVID-19 who did not receive steroid administration and initiated treatment within 4 days from the onset, the risk of illness worsening was significantly lower in the Kampo group than in the non-Kampo group (odds ratio=0.113, 95% confidence interval: 0.014-0.928, p=0.0424). Conclusion Early Kampo treatment may suppress illness worsening risk in COVID-19 cases without steroid use. Further randomized controlled studies are needed to confirm the clinical benefit of Kampo medicine for COVID-19.

OBJECTIVE: To develop versatile and interactive model classes by generating the contents of Kampo classroom sessions that can be taught by instructors who are not familiar with Kampo medicine. METHODS: In 2018, we conducted Kampo classroom sessions among fourth-year medical students at Kyushu University in which we incorporated new content. A videotaped digest edition of the classes was sent to Kampo medicine instructors in medical schools throughout Japan. An online questionnaire was given to the instructors regarding effectiveness of the class content (Q1) and whether they would introduce the content in their classes (Q2). We modified the curriculum according to survey responses and conducted revised classroom sessions again in 2019. A second online survey was given and we finalized the model classes. We compared survey responses between staff and instructors (group A) and non-specialists in Kampo medicine (group B). RESULTS: In 2018, there were significant differences between groups A (44) and B (52) regarding a patient's story and case report (Q1). In 2019, there were significant differences between groups A (42) and B (54) regarding the case report using e-learning(Q1) and an instructor's experience (Q2). CONCLUSIONS: We propose that Kampo medicine classes should incorporate an instructor's experience and interactive case report presentation using e-learning.

Background: Alzheimer's disease (AD) is a progressive neurodegeneration and is the most prevalent form of dementia. Intervention at an early stage is imperative. Although three acetylcholinesterase inhibitors (AChEIs) are currently approved for the treatment of mild AD, they are not sufficiently effective. Novel treatments for mild AD are of utmost importance. Objective: To assess the effectiveness of hachimijiogan (HJG), a traditional Japanese herbal medicine (Kampo), in the treatment of mild AD. Methods: This exploratory, open-label, randomized, multicenter trial enrolled patients with mild AD whose score on the Mini Mental State Examination (MMSE) was over 21points. All participants had been taking the same dosage of AChEI for more than 3 months. The participants were randomly assigned to an HJG group taking HJG extract 7.5 g/day in addition to AChEI or to a control group treated only with AChEI. The primary outcome was the change from baseline to 6 months post treatment initiation on the Alzheimer's Disease Assessment Scale-cognitive component- Japanese version(ADAS-Jcog). The secondary outcomes were change from baseline of the Instrumental Activity of Daily Life (IADL), Apathy scale, and Neuropsychiatric Inventory (NPI) -Q score. Results: Among the 77 enrollees, the data of 69(34 HJG and 35 control)were available for analysis. The difference in the change of ADAS-Jcog from baseline to 6 months of the HJG and control groups was 1.29 (90% Confidence interval (CI), -0.74 to 3.32 p = 0.293). In the subgroup analysis, the differences in the change from baseline to 3 and 6 months for women were 3.70 (90% CI ,0.50 to 6.91, p = 0.059) and 2.90 (90% CI,0.09 to 5.71, p = 0.090), respectively. For patients over 65 years, the difference at 3 months was 2.35 (90%CI, 0.01 to 4.68 p = 0.099). No significant differences were found between the HJG and control groups in IADL score, Apathy scale, or NPI-Q score. Conclusion: Although not conclusive, our data indicate that HJG has an adjuvant effect for acetylcholinesterase inhibitors and that it delays the deterioration of the cognitive dysfunction of mild Altzheimer's disease patients.

RESUMEN
OBJECTIVE: We aimed to test our hypothesis that traditional Japanese (Kampo) medicine, hochuekkito (Hochu-ekki-to: HET) has a preventive effect for the symptoms on COVID-19. TRIAL DESIGN: The study is designed as a multi-center, interventional, parallel-group, randomized (1:1 ratio), investigator sponsored, two-arm study. PARTICIPANTS: Six thousand participants will be recruited from healthy hospital workers in 7 Japanese University Hospitals. INCLUSION CRITERIA: 1. Age from 20 to 75 years old at the time of registration 2. Asymptomatic and body temperature below 37°C at the time of registration 3. Capable of eating orally Exclusion criteria: 1. Previous upper respiratory inflammation due to viral infection (including suspected COVID-19) 2. Taking immunosuppressants 3. Allergic to the Kampo medicines used in this study 4. History of hypokalaemia, severe hypertension, severe liver dysfunction, and interstitial pneumonia 5. Regularly taking other Kampo medicines 6. Pregnant or possibly pregnant 7. Participating in other research 8. Judged to be unsuitable for this study by the doctor in charge INTERVENTION AND COMPARATOR: Kampo group: participants receive HET in 9 tablets 2 times per day for 8 weeks. CONTROL GROUP: participants receive placebo in the same dosage as the Intervention group - 9 tablets 2 times per day for 8 weeks. Placebo tablets are identical in appearance and package to HET. Taste of placebo is different from that of HET. The Ohsugi Pharmaceutical Co. Ltd, Osaka, Japan manufactured the placebo and HET. MAIN OUTCOMES: Primary outcome: Number of patients with a SARS-CoV-2 RNA by ploymerase chain reaction (PCR) positive result with at least one symptom (fever, cough, sputum, malaise, shortness of breath) during the 12-week study period (including the 4-week observation period after oral administration). SECONDARY OUTCOMES: 1. Period from infection to onset 2. Period from the appearance of symptoms to the disappearance of PCR positive 3. Number of days until the appearance or improvement of symptoms 4. Severe stage: presence of hospitalization 5. Shock stage: ICU management required for mechanical ventilation, shock vitals or failure of organ(s) other than lungs Safety endpoints include numbness in the hands and/or feet, edema, skin rash or other allergic symptoms, and gastric discomfort. RANDOMISATION: Patients are randomized (1:1 ratio) to each group using minimization implemented with the Electric data capture system (DATATRAK Enterprise Cloud), with balancing of the arms with age range (under 50 years of age or not) and having a history of risk factors for COVID-19 (cardiovascular disease, hypertension, diabetes, respiratory diseases). BLINDING (MASKING): Only participants will be randomized. NUMBERS TO BE RANDOMISED (SAMPLE SIZE): The main research hypothesis of this study is that Kampo medicines significantly prevent the onset of COVID-19. It is assumed that the infection rate before the administration of the drug under consideration will be 0% and that the incidence of COVID-19 thereafter will be 2- 3%, of which 70%-80% will show symptoms of COVID-19. Assuming that the pharmaceutical effect of the drug will be effective in 50% of patients and that the incidence rates in the placebo and drug groups will be 1.4%-2.4% and 0.7%-1.2%, respectively, the placebo is calculated at 2%, and the study drug at 1%. Since the frequency of verification is low and the number of cases will be large, we set a total of 10 analyses (9 interim analyses and a final analysis). Since the number of cases at the time of the final analysis will be 4,986 under the conditions of α = 0.05 and a power of 80% by the Peto method. We set at 600 cases in each interim analysis with an estimated dropout rate of 16.9%. Finally, the total number of cases is set to 6,000 with 3,000 in the placebo group and 3,000 in the HET group. TRIAL STATUS: Protocol version 1.3 of October 23rd , 2020. Recruitment start (expected): December 1st, 2020. Recruitment finish (expected): December 31st, 2022. TRIAL REGISTRATION: This trial is registered in the Japan Registry of Clinical Trials (jRCT) ( jRCTs031200150 ) on 14 October 2020. FULL PROTOCOL: The full protocol is attached as an additional file, accessible from the Trials website (Additional file 1). In the interest of expediting dissemination of this material, the familiar formatting has been eliminated; this Letter serves as a summary of the key elements of the full protocol.

OBJECTIVES: We aimed to test our hypothesis that additional administration of traditional Japanese (Kampo) medicine, kakkonto (kakkon-to: KT) and shosaikotokakikyosekko (sho-saiko-to-ka-kikyo-sekko: SSKKS), is more effective in relieving symptoms and preventing the onset of severe infection in mild-to-moderate COVID-19 patients compared to those treated only with conventional treatment. TRIAL DESIGN: The study is designed as a multi-center, interventional, parallel-group, randomized (1:1 ratio), investigator-sponsored, two-arm study. PARTICIPANTS: Patients and inpatients will be recruited from 8 Japanese academic and non-academic hospitals. The inclusion and exclusion criteria are as follows: Inclusion criteria: 1. Diagnosed as positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) 2. Clinical stages of mild-to-moderate COVID-19 3. Symptomatic 4. ≥ 20 years of age 5. Male or female 6. Ability to communicate in Japanese 7. Outpatients and inpatients 8. Provided informed consent Exclusion criteria: 1. Difficulty in providing informed consent due to dementia, psychosis, or psychiatric symptoms 2. Allergic to Kampo or Western medicines used in this study 3. Pregnant and lactating 4. Unable to follow up 5. Participating in another clinical trial or interventional study 6. Hypokalemic or taking oral furosemide or steroids 7. Determined unsuitable for this study by the physician INTERVENTION AND COMPARATOR: Patients in the control group will receive conventional treatment with antipyretics, painkillers, or antitussives for symptoms that occurred after they contracted the SARS-CoV-2 infection. Patients in the Kampo group will receive 2.5 g of KT (TJ-1@TSUMURA and Co.) and 2.5 g of SSKKS (TJ-109@TSUMURA and Co.) 3 times a day, orally, for 14 days in addition to the conventional treatment as mentioned above. MAIN OUTCOMES: The number of days till at least one of the symptoms (fever, cough, sputum, malaise, shortness of breath) improves in the first 14 days of treatment. To assess the cough, sputum, malaise, and shortness of breath, a numeric rating scale will be used to define improvement in terms of a 2-point decrease in the number of days from the start of treatment for at least 2 days. Fever will be defined as an improvement when the temperature is less than 37 °C. RANDOMIZATION: Patients are randomized (1:1 ratio) to each group using the minimization method, with balancing of the arms with severity of disease stage and patient age (< 65, 65 to < 75, or ≥ 75 years). Computer-generated random numbers will be used for the minimization method. BLINDING (MASKING): Open-label with no blinding NUMBERS TO BE RANDOMIZED (SAMPLE SIZE): The main research hypothesis of this study is that the combination of Kampo medicine and conventional treatment will significantly improve the patients' symptoms (fever, fatigue, cough, sputum, and shortness of breath) during the first 14 days of treatment as compared with conventional treatment alone. Concerning the analysis of the primary endpoint, the duration of time before improvement of at least one of the common cold-like symptoms (fever, malaise, cough, sputum, and shortness of breath) will be estimated using the Kaplan-Meier method, and the survival curves will be compared between groups using the log-rank test. Assuming this method of analysis and based on previous studies reporting the efficacy of Kampo medicine for COVID-19 and H1N1 influenza patients, the median survival time in the Kampo medicine group is estimated as 3 days; this time will be 1.5 times longer in the control group. Assuming a one-sided significance level of 5%, a power of 70%, and an allocation ratio of 1:1, the required sample size is calculated as 126 cases. To compensate for a loss in follow-up, we plan to include 150 cases in both groups (Kampo group = 75, control group = 75). TRIAL STATUS: Protocol version 1.2 as of August 20, 2020 Recruitment start (expected): October 1, 2020 Recruitment finish (expected): October 31, 2023 TRIAL REGISTRATION: Japan Registry of Clinical Trials (jRCT) jRCTs021200020 .

BACKGROUND: Dementia among the Japanese aged 65 years or over population is estimated to approach about 700 million cases by 2025, and a corresponding rapid increase in Alzheimer disease (AD) can also be expected. The ballooning number of dementia patients, including AD, is creating major medical and social challenges. At present, only 3 drugs are recognized for the treatment of mild AD, and these are only used to alleviate symptoms. Although new therapies are needed to treat mild AD, insufficient development of disease-modifying drugs is being done. METHODS/DESIGN: The aim of this exploratory, open standard, treatment-controlled, randomized allocation, multicenter trial is to determine the efficacy of the traditional Japanese Kampo medicine hachimijiogan (HJG) on the cognitive dysfunction of mild AD.Eighty-six patients with AD diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 and as mild AD according to the Mini Mental State Examination (MMSE ≥21) will be included. All will already have been taking the same dose of Donepezil, Galantamine, or Rivastigmine for more than 3 months. The patients will be randomly assigned to receive additional treatment with HJG or to continue mild AD treatment without additional HJG. The primary endpoint is the change from baseline of the Alzheimer's Disease Assessment Scale-cognitive component- Japanese version (ADAS-Jcog). ADAS-Jcog is a useful index for detecting change over time that investigates memory and visuospatial cognition injury from the early stage. The secondary endpoints are the changes from baseline of the Instrumental Activity of Daily Life, Apathy scale, and Nueropsychiatric Inventory scores. In this protocol, we will examine the Geriatric depression scale and do Metabolome analysis as exploratory endpoints. The recruitment period will be from August 2019 to July 2021. DISCUSSION: This is the first trial of Kampo medicine designed to examine the efficacy of HJG for the cognitive dysfunction of patients with mild AD. TRIAL REGISTRATION: This trial was registered on the Japan Registry of Clinical trials on 2 August 2, 2019 (jRCTs 071190018).

OBJECTIVES: To clarify competencies for inclusion in our curriculum that focuses on developing leaders in community medicine. DESIGN: Qualitative interview study. SETTING: All six regions of Japan, including urban and rural areas. PARTICIPANTS: Nineteen doctors (male: 18, female: 1) who play an important leadership role in their communities participated in semistructured interviews (mean age 48.3 years, range 34-59; mean years of clinical experience 23.1 years, range 9-31). METHOD: Semistructured interviews were held and transcripts were independently analysed and coded by the first two authors. The third and fourth authors discussed and agreed or disagreed with the results to give a consensus agreement. Doctors were recruited by maximum variation sampling until thematic saturation was achieved. RESULTS: Six themes emerged: (1)'Medical ability': includes psychological issues and difficult cases in addition to basic medical problems. High medical ability gives confidence to other medical professionals. (2)'Long term perspective': the ability to develop a long-term, comprehensive vision and to continuously work to achieve the vision. Cultivation of future generations of doctors is included. (3) 'Team building':the ability to drive forward programmes that include residents and local government workers, to elucidate a vision, to communicate and to accept other medical professionals. (4)'Ability to negotiate': the ability to negotiate with others to ensure that programmes and visions progress smoothly (5) 'Management ability': the ability to run a clinic, medical unit or medical association. (6) 'Enjoying oneself': doctors need to feel an attraction to community medicine, that it be fun and challenging for them. CONCLUSIONS: We found six competencies that are needed by leaders in the field of community medicine. The results of this study will contribute to designing a curriculum that develops such leaders.

A 39-year-old Japanese man presented to our hospital complaining of left chest pain and rash on the hands and feet. Plain thoracic computed tomography (CT) revealed multiple nodular shadows in the left lower lobe of the lung. A diagnosis of secondary syphilis was made based on the appearance of the rash and positive serologic tests for syphilis. The patient was started on amoxicillin but was switched to minocycline due to amoxicillin-induced rash on both forearms. Thoracic CT after five months of treatment revealed that the multiple lung nodular shadows had contracted, and secondary syphilis with pulmonary involvement was diagnosed.

Hachimijiogan (HJG) is a traditional herbal medicine that improves anxiety disorders in patients with dementia. In this study, we tested the hypothesis that HJG exerts neurotrophic factor-like effects to ameliorate memory impairment in Alzheimer disease (AD) model rats. First, we describe that HJG acts to induce neurite outgrowth in PC12 cells (a rat pheochromocytoma cell line) like nerve growth factor (NGF) in a concentration-dependent manner (3 µg/ml HJG, p < 0.05; 10-500 µg/ml HJG, p < 0.001). While six herbal constituents of HJG, Rehmannia root, Dioscorea rhizome, Rhizoma Alismatis, Poria sclerotium, Moutan bark, and Cinnamon bark, could induce neurite outgrowth effects, the effect was strongest with HJG (500 µg/ml). Second, we demonstrated that HJG-induced neurite outgrowth was blocked by an inhibitor of cAMP response element binding protein (CREB), KG-501 (10 µM, p < 0.001). Moreover, HJG was observed to induce CREB phosphorylation 20-90 min after treatment (20 min, 2.50 ± 0.58-fold) and CRE-mediated transcription in cultured PC12 cells (500 µg/ml, p < 0.01; 1000 µg/ml, p < 0.001). These results suggest a CREB-dependent mechanism underlies the neurotrophic effects of HJG. Finally, we examined improvements of memory impairment following HJG treatment using a Morris water maze in AD model animals (CI + Aß rats). Repeated oral administration of HJG improved memory impairment (300 mg/kg, p < 0.05; 1000 mg/kg, p < 0.001) and induced CREB phosphorylation within the hippocampus (1000 mg/kg, p < 0.01). Together, our results suggest that HJG possesses neurotrophic effects similar to those of NGF, and can ameliorate cognitive dysfunction in a rat dementia model via CREB activation. Thus, HJG could potentially be a substitute for neurotrophic factors as a treatment for dementia.
RESUMEN
BACKGROUND: In Japanese Kampo medical practice, suidoku (fluid disturbance) is one of the most important concepts for selecting the proper medication. Suidoku is an excessive or uneven distribution of fluid that is indicated by splashing sounds and pitting edema. However, few objective reports about suidoku have been published. Bioelectrical impedance analysis (BIA) uses resistance values obtained from weak electrical currents to estimate body composition, including intracellular and extracellular water and muscle and fat mass. In this study, we used BIA to search for objective factors that can discriminate the various types of suidoku. METHODS: Two hundred twenty-nine patients who visited the Kampo Medicine Clinic of Kyushu University Hospital from June 2010 to August 2015 were divided into non-suidoku (n = 180, 80 male and 100 female), splashing sound (n = 32, 8 male and 24 female) and edema groups (n = 17, 5 male and 12 female). Body composition values were taken from the electronic medical records of InBody730 (a vertical, segmental, multi-frequency analyzer by InBody, Tokyo Japan) testing done at the initial visit. Various parameters of the body composition values of female in the non-suidoku and suidoku groups (splashing sound and edema groups) were compared: there were too few male patients to provide significance. RESULTS: The age and body weight were significantly lower in the splashing sound group than in the non-suidoku group (p < 0.05). In contrast, the body weight of the edema group was significantly heavier than that of the non-suidoku group (p < 0.05). In ROC analysis, the percent Body Fat ≤ 27.8 %, Muscle Mass Index of the Trunk ≤ 6.5 kg/m2, VFA (Visceral fat area) ≤ 5.4 and BMI ≤ 19.2 kg/m2 were associated with splashing sound, and Muscle Mass Index of Legs ≥ 4.8 kg/m2 and BMI ≥ 21.4 kg/m2 were associated with edema. CONCLUSION: Our data suggest that the use of this type of BIA to estimate body composition would be a useful tool for the diagnosis of suidoku for women.

Cinnamon bark is commonly used in traditional Japanese herbal medicines (Kampo medicines). The coumarin contained in cinnamon is known to be hepatotoxic, and a tolerable daily intake (TDI) of 0.1 mg/kg/day, has been quantified and used in Europe to insure safety. Risk assessments for hepatotoxicity by the cinnamon contained in foods have been reported. However, no such assessment of cinnamon bark has been reported and the coumarin content of Kampo medicines derived from cinnamon bark is not yet known. To assess the risk for hepatotoxicity by Kampo medicines, we evaluated the daily coumarin intake of patients who were prescribed Kampo medicines and investigated the relation between hepatotoxicity and the coumarin intake. The clinical data of 129 outpatients (18 male and 111 female, median age 58 years) who had been prescribed keishibukuryogankayokuinin (TJ-125) between April 2008 and March 2013 was retrospectively investigated. Concurrent Kampo medicines and liver function were also surveyed. In addition to TJ-125, the patients took some of the other 32 Kampo preparations and 22 decoctions that include cinnamon bark. The coumarin content of these Kampo medicines was determined by high performance liquid chromatography (HPLC). TJ-125 had the highest daily content of coumarin (5.63 mg/day), calculated from the daily cinnamon bark dosage reported in the information leaflet inserted in each package of Kampo medicine. The coumarin content in 1g cinnamon bark decoction was 3.0 mg. The daily coumarin intake of the patients was 0.113 (0.049-0.541) mg/kg/day, with 98 patients (76.0%) exceeding the TDI. Twenty-three patients had an abnormal change in liver function test value, but no significant difference was found in the incidence of abnormal change between the group consuming less than the TDI value (6/31, 19.4%) and the group consuming equal to or greater than the TDI value (17/98, 17.3%). In addition, no abnormal change related to cinnamon bark was found for individual patients. This paper was done to assess the risk of hepatotoxicity by the coumarin contained in Kampo medicines and to clarify whether or not the Kampo preparations in general use that contain cinnamon bark may be safely used in clinical practice.
RESUMEN
BACKGROUND: Previous clinical studies have shown that the circulating level of endostatin is related to kidney injury. We hypothesized that the impact of HbA1c, fasting, and postprandial plasma glucose on urinary albumin excretion would be related to the serum endostatin level. METHODS: A cross-sectional, community-based population study of 1057 Japanese residents was conducted. Of these subjects, 162 with a fasting plasma glucose value between 5.5 and 6.9 mmol/L and an HbA1c level of <6.5 % received an oral glucose tolerance test, had serum endostatin measured, and had the urinary albumin/creatinine ratio (UACR) calculated. RESULTS: In multivariate analysis, 2-h postprandial plasma glucose (ß = 0.26, P < 0.01) was significantly associated with log-transformed UACR, independently of fasting plasma glucose (ß = 0.14, P = 0.28) and HbA1c (ß = -0.08, P = 0.57). When divided by the median value of endostatin (82.2 ng/mL), 2-h postprandial plasma glucose (ß = 0.38, P = 0.01) remained significantly associated with the log-transformed UACR of the participants below the median, while the fasting plasma glucose (ß = 0.34, P = 0.046) was independently associated with the log-transformed UACR of participants above the median. CONCLUSION: Postprandial plasma glucose was independently associated with the urinary albumin excretion of the residents with prediabetes. Moreover, this relationship was limited to residents with a serum endostatin level below the median.

Hepatitis C virus (HCV) infection is a serious global health problem. Previous studies have suggested that the interleukin 28B (IL28B) rs8099917 genotype is related to spontaneous clearance of HCV in Caucasian populations. Our objective was to investigate the association of the IL28B rs8099917 genotype with spontaneous clearance of HCV by community-dwelling Japanese. A cross-sectional community-based population study of 993 Japanese residents was conducted. Based on anti-HCV antibody and HCV RNA levels, 50 subjects were assigned to the spontaneous-clearance group, 155 to the chronic-infection group, and 788 to the control group. Logistic regression analysis was done to examine the roles of the IL28B rs8099917 genotype and sex. To analyze the interactions between these factors, an "IL28B rs809991 genotype × sex" interaction term was included in the multivariate analysis. Significantly more subjects in the spontaneous-clearance group than in the chronic-infection group had the favorable IL28B rs8099917 genotype and were female. Multivariate logistic regression analysis extracted the favorable IL28B rs8099917 TT genotype (odds ratio [OR] 9.39; 95% confidence interval [CI], 2.16-40.83, P = 0.003) and female sex (OR, 2.27; 95% CI, 1.16-4.45, P = 0.017) as factors contributing to the spontaneous clearance of HCV. No significant interaction was found between the IL28B rs8099917 genotype and sex (P for interaction = 0.428). Both the favorable IL28B rs8099917 genotype and female sex were associated with the spontaneous clearance of HCV in this Japanese population.

BACKGROUND: The relation between tongue color and gastroesophageal disease is unclear. This study was done to investigate the associations between tongue color (TC), endoscopic findings, Helicobacter.pylori infection status, and serological atrophic gastritis (SAG). METHODS: The participants were 896 residents of Ishigaki Island, Okinawa, aged 28-86 years. The tongue was photographed, esophagogastroduodenoscopy was done, and serum antibody to H.pylori was measured. SAG was defined as a serum Pepsinogen (PG)Ilevel ≤70 ng/ml and a PGI/IIratio ≤3.0. TC was measured by the device-independent international commission on Illumination 1976 L*a*b* color space standards at four points: (1) edge, (2) posterior, (3) middle, and (4) apex. We also calculated the ratio of the tongue edge to the three other measured points to examine the association between the coating of the tongue and the endoscopic and laboratory findings. RESULTS: Participants were excluded who had two or more endoscopic findings (n = 315) or who had SAG without seropositivity to H.pylori (n = 33). The remaining 548 participants were divided into three groups: SAG and seropositive to H.pylori (n = 67), seropositive to H.pylori alone (n = 56), and without SAG and seronegative for H.pylori (n = 425). We divided 425 residents into a single endoscopic finding positive group (n = 207) and a negative group, which served as a control (n = 218). The most frequent single endoscopic finding was esophageal hernia (n = 110), followed by erosive esophagitis (n = 35) and erosive gastritis (EG) (n = 45). EH was significantly associated with TC (2b*/1b*) (P < 0.05). EG was significantly associated with TC (3a*, 3b*) (P < 0.05). Seropositivity to H.pylori was significantly associated with TC (3 L*, 3 L*/1 L*) (P < 0.05, <0.01), and seropositivity to both H.pylori and SAG was significantly associated with TC (3 L*/1 L*) (P < 0.05). Multivariate analysis extracted TC (3a*, 3b*) as an independent factor associated with a differential diagnosis of EG (Odds ratio (OR) 2.66 P = 0.008, OR 2.17 P = 0.045). CONCLUSIONS: The tongue body color of the middle area reflects acute change of gastric mucosa, such as erosive gastritis. Tongue diagnosis would be a useful, non-invasive screening tool for EG.

RESUMEN
OBJECTIVE: To examine whether or not subclinical atherosclerosis independently predicts the incidence of chronic kidney disease (CKD) in the Japanese general population. METHODS: This study is part of the Kyushu and Okinawa Population Study (KOPS), a survey of vascular events associated with lifestyle-related diseases. Participants who attended both baseline (2004-2007) and follow-up (2009-2012) examinations were eligible. The common carotid intima-media thickness (IMT) was assessed for each participant at baseline. The end point was the incidence of CKD, defined as an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m(2) during the follow-up of participants without CKD at baseline. RESULTS: During the five-year follow-up, 224 of the 1824 participants (12.3%) who developed CKD had higher carotid IMT (0.74 ± 0.22 vs. 0.65 ± 0.14 mm, P < 0.001), higher triglycerides (1.6 ± 0.8 vs. 1.3 ± 0.7 mmol/L, P < 0.001), and lower high density lipoprotein cholesterol (1.5 ± 0.4 vs. 1.6 ± 0.4 mmol/L, P < 0.001) at baseline than those who did not. In logistic regression analysis adjusted for significant covariates, eGFR (Odds ratio [OR] 0.83, 95% confidence interval (CI) 0.80-0.85, P < 0.001), carotid IMT (0.10 mm increase: OR 1.17, 95% CI 1.04-1.33, P = 0.010), and triglycerides (OR 1.35, 95% CI 1.06-1.73, P = 0.015) at baseline were independent predictors for the development of CKD. CONCLUSIONS: Higher carotid IMT and hypertriglyceridemia were independently associated with the development of CKD in the population studied.
