小児急性リンパ性白血病のL-アスパラギナーゼを含む寛解導入療法ではトロンピン・プラスミン生成試験において著明な線溶抑制を主体とする凝固障害を示す。
Get PDFBackground: L-asparaginase (L-Asp)-associated thromboembolisms are serious complications in pediatrics patients with acute lymphoblastic leukemia (ALL), especially at ≥10.0 years old, but the pathogenesis remains to be clarified. Procedure: We conducted a multicenter, prospective study of 72 patients with ALL aged 1.0 to 15.2 years treated with either a Berlin-Frankfurt-Münster (BFM) 95-ALL oriented regimen or Japan Association of Childhood Leukemia Study ALL-02 protocol. We divided patients into each treatment protocol and investigated the dynamic changes in coagulation and fibrinolysis using simultaneous thrombin and plasmin generation assay. Patients' plasma samples were collected at the prephase (T0), intermittent phase (T1), and postphase of L-Asp therapy (T2), and postinduction phase (T3). Measurements of endogenous thrombin potential (T-EP) and plasmin peak height (P-Peak) were compared to normal plasma. Results: None of the cases developed thromboembolisms. Median ratios of T-EP and P-Peak for the controls in the JACLS group were 1.06 and 0.87 (T0), 1.04 and 0.71 (T1), 1.02 and 0.69 (T2), and 1.20 and 0.92 (T3), respectively, while those in the BFM group were 1.06 and 1.00 (T0), 1.04 and 0.64 (T1), 1.16 and 0.58 (T2), and 1.16 and 0.85 (T3), respectively. In particular, P-Peak ratios were depressed at T1 and T2 compared to T0 in the BFM group (P < .01). Moreover, P-Peak ratios in patients ≥10.0 years old were lower at T1 in the BFM group (P = .02). Conclusions: The results demonstrated that hemostatic dynamics appeared to shift to a hypercoagulable state with marked hypofibrinolysis associated with L-Asp therapy, especially in patients ≥10.0 years old following the BFM regimen.博士（医学）・甲第722号・令和元年12月5日© 2019 Wiley Periodicals, Inc.This is the pre-peer reviewed version of the following article: [https://onlinelibrary.wiley.com/doi/full/10.1002/pbc.28016], which has been published in final form at [https://doi.org/10.1002/pbc.28016].

Relationship Between Clinical Competence of Undergraduate Nursing Students and Their Understanding of Children.
Get PDFThe objective of this study is to examine the relationship between clinical competence of undergraduate nursing students and their understanding of children. Study methods consisted of a questionnaire survey that used scales developed to measure nursing students' clinical competence and understanding of children. The study was conducted with the approval of the ethics committee of Nara Medical University. Two hundred and fifty-seven nursing students participated in this survey, and of these, two hundred and thirty-three were subject to analysis. Of the nursing students surveyed, 183 (79%) reported having experience with children, and there was no significant difference in experience with children between students in different years of study.Nursing students' experience with children involved playing with them, helping them with learning or playing sports, and raising them. The children they had experience with were pre-school and school-aged children. The study found a correlation between the nursing students' understanding of children and clinical competence. In addition, there was a significant relationship between nursing students' experience with children and their understanding of children. There was no significant difference in third-year students' understanding of children as compared to that of fourth-year students, who had completed practical training. There was,however, a significant difference in clinical competence between these two groups. These results indicate that nursing students' understanding of children is connected to their clinical competence, and that practical nursing training is necessary to increase the clinical competence of nursing students. In addition, educational intervention that deepens nursing students' understanding of sick children is important to improving clinical competence
インスリン使用患者における新規Self-efficacy質問紙(ITSS)の開発に関する臨床研究
No full textAIMS/INTRODUCTION: Although patient self-efficacy is known to affect adherence to therapy, no available tool measures self-efficacy of insulin therapy administration while addressing the entire therapeutic process and management. In light of this, we developed the 'Insulin Therapy Self-efficacy Scale (ITSS)'. MATERIALS AND METHODS: Development of the ITSS involved three phases: (i) item generation and creation of a questionnaire draft; (ii) testing and correcting the items through interviews with patients; and (iii) a multicenter, single-arm study to validate the questionnaire. RESULTS: A factor analysis and Cronbach's α both confirmed good internal consistency in the patients' confidence regarding the following four factors: the insulin injection procedure, insulin titration, glycemic control and ability to cope with hypoglycemia. Reproducibility was confirmed using weighted κ statistics and intraclass correlations. Good concurrent validity was confirmed with two other questionnaires. The ITSS score was also found to correlate with several patient characteristics and clinical parameters, as well as with a better adherence to injected insulin therapy 6 months later, suggesting the predictive validity of this scale. CONCLUSIONS: The ITSS is a reliable and valid tool for assessing and quantifying patients' self-efficacy. The ITSS estimation of self-efficacy can predict a patient's glycemic control and future adherence to insulin therapy. These characteristics will ensure the usefulness of the ITSS in ensuring a successful therapeutic process for patients and physicians.博士（医学）・甲第711号・令和元年6月26日© 2018 The Authors.

季節と天候による骨折リスクの差 : 日本のレセプト情報データベースを用いた、全ての年齢・部位に関する包括的な分析
Get PDFAlthough age- and season-specific effects on fracture risk have been reported, the effects of seasonality across different age groups and for different fracture sites have not yet been clarified. Therefore, our study aimed to comprehensively investigate the effects of seasonality on fracture risk across age and fracture sites using a large-scale population database of fracture incidence. Fracture data were accumulated over a 3-year period in the region of Tokyo and in surrounding areas, which accounts for a total population of 42 million. Information on fracture occurrence, fracture site, and patient demographics were obtained from the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB). Over the study period, 508,051 fractures were identified across the following five age groups: 0-19, 20-39, 40-64, 65-79, and 80+ years. The incidence rate for fractures in 10 site groups was calculated. Fracture risk was the highest in the spring and autumn for children aged 0-19 years and was the highest in the winter for elderly individuals (65-79 and 80+ years). Toe fractures, which occurred more frequently in the summer, were the most notable exception. The risk of fracture of the distal radius and hip was associated with daily temperature and rainfall and was elevated on days with a mean temperature higher than that of the previous day. Fracture risk exhibited seasonal variations that differed between children and elderly individuals and between toe fractures and fractures at other sites. These findings can help us understand the epidemiology of fractures and develop preventive strategies, as well as aid in the allocation of healthcare resources.博士（医学）・甲第718号・令和元年9月27
ダパグリフロジン投与における肥満２型糖尿病患者の治療満足度への影響：a patient reported outcome study (PRO study).
Get PDFBackground: The benefits of sodium glucose cotransporters 2 (SGLT2) inhibitors in patients with type 2 diabetes mellitus include plasma glucose control, reduction in body weight and blood pressure, and low risk of hypoglycemia, although they may also cause genitourinary infections, polyuria, or volume depletion. It is not clear whether dapagliflozin, an SGLT2 inhibitor, improves treatment satisfaction among patients in a comprehensive way despite the negative side effects. This study assessed the effect of dapagliflozin on glycosylated hemoglobin (HbA1c), body weight, and treatment satisfaction in overweight patients with type 2 diabetes mellitus treated with oral hypoglycemic agents. Methods: This multicenter, open-label, single-arm observational study included patients with type 2 diabetes mellitus administering dapagliflozin 5 or 10 mg per day for 14 weeks. Changes in treatment satisfaction were evaluated using a new version of the Oral Hypoglycemic Agent-Questionnaire (OHA-Q ver. 2) consisting of 23 items. Correlation between treatment satisfaction and HbA1c levels and body weight were analyzed using the Spearman's rank-correlation coefficient. Results: Of the 221 patients enrolled, 188 completed the study. Mean HbA1c decreased from 7.8 ± 0.7% (62.1 ± 7.5 mmol/mol) to 7.3 ± 0.8% (55.9 ± 8.7 mmol/mol) (change - 0.6 ± 0.7%, P < 0.001) and body weight decreased from 82.5 ± 14.6 to 80.7 ± 14.8 kg (change - 2.3 ± 2.8 kg, P < 0.001). OHA-Q ver. 2 was validated as well, the mean OHA-Q ver. 2 total score increased from 44.3 ± 9.4 to 46.6 ± 9.8 (best score 69, worst score 0; change 2.3 ± 6.6, P < 0.001). The change in body weight significantly correlated with the OHA-Q ver. 2 total score (Spearman's ρ = - 0.17, P = 0.035). The change in HbA1c levels significantly correlated with the satisfaction subscale score (Spearman's ρ = - 0.19, P = 0.011). Conclusions: Dapagliflozin significantly improved treatment satisfaction among patients with type 2 diabetes mellitus for 14 weeks. Body weight loss significantly correlated with treatment satisfaction.Trial registration UMIN-CTR: UMIN000016304.博士（医学）・甲第694号・平成31年3月15日© The Author(s) 2018.

人工膝関節置換術後の関節周囲感染が疑われる症例の発生頻度は、術中麻酔維持使用薬剤の選択と関連するか（プロポフォールによる全静脈麻酔と、セボフルランでの麻酔維持での比較）：後ろ向きコホート研究
Get PDFPURPOSE: Periprosthetic joint infection is a serious complication of total knee arthroplasty. Though there are many factors that might increase its risk, the use of propofol for maintaining general anesthesia could theoretically increase the incidence of infection because of its lipid component that supports bacterial growth. Nevertheless, the relationship between anesthetic maintenance agents and the occurrence of periprosthetic joint infection remains uncertain. The purpose of this study was to compare the incidence of suspected early-onset periprosthetic joint infection between patients undergoing total knee arthroplasty under propofol vs sevoflurane anesthesia. METHODS: We conducted a retrospective cohort study of patients in the national inpatient Diagnosis Procedure Combination database in Japan who underwent total knee arthroplasty. Suspected periprosthetic joint infection was surrogately defined as the need for arthrocentesis or debridement within 30 days of surgery. Propensity score matching was performed between patients who received either propofol or sevoflurane for anesthetic maintenance to determine the proportion of those with infection. RESULTS: Eligible patients (n = 21,899) were categorized into either the propofol (n = 7,439) or sevoflurane (n = 14,460) groups. In the 5,140 propensity-matched patient pairs, there was no significant difference in the proportion of arthrocentesis or debridement [1.3% propofol vs 1.7% sevoflurane; respectively (relative risk, 0.76; 95% CI, 0.55 to 1.04; P = 0.10)] between the groups. The mean (SD) length of stay in the propofol group was significantly longer than in the sevoflurane group [32.5 (18.4) days vs 31.4 (14.4) days, respectively; mean difference, 1.1; 95% CI, 0.5 to 1.8; P < 0.001]. CONCLUSION: Propensity score analysis suggested no significant association between the choice of anesthetic maintenance agent and the occurrence of suspected early-onset periprosthetic joint infection in patients undergoing total knee arthroplasty.博士（医学）・甲第700号・平成31年3月15日© Canadian Anesthesiologists' Society 2018This is a post-peer-review, pre-copyedit version of an article published in Canadian journal of anaesthesia.
