Japanese Initiative for Education in Pharmaceutical Medicine and Clinical Research Training

Development of new medicines has become increasingly difficult with less possibility of success in seeds-finding and ever rising operational costs. Failure to comply with ethical standards for human research protection also erodes social trust in clinical development. In order to develop competence of professionals in medicines development such as clinical investigators and drug development scientists, a variety of educational courses and training programs have been developed and executed worldwide. As Japan is no exception and shares the same concerns, significant governmental and non-governmental efforts have been made to invest in the development of academic educational courses and adherence to international standards. This article introduces examples of the adoption of technologies to realize a user-friendly and sustainable learning management as well as an adaptation of syllabuses and core curricula to meet international standards in the era of global medicines development

Transcriptional repression and DNA hypermethylation of a small set of ES cell marker genes in male germline stem cells

BACKGROUND: We previously identified a set of genes called ECATs (ES cell-associated transcripts) that are expressed at high levels in mouse ES cells. Here, we examine the expression and DNA methylation of ECATs in somatic cells and germ cells. RESULTS: In all ECATs examined, the promoter region had low methylation levels in ES cells, but higher levels in somatic cells. In contrast, in spite of their lack of pluripotency, male germline stem (GS) cells expressed most ECATs and exhibited hypomethylation of ECAT promoter regions. We observed a similar hypomethylation of ECAT loci in adult testis and isolated sperm. Some ECATs were even less methylated in male germ cells than in ES cells. However, a few ECATs were not expressed in GS cells, and most of them targets of Oct3/4 and Sox2. The Octamer/Sox regulatory elements were hypermethylated in these genes. In addition, we found that GS cells express little Sox2 protein and low Oct3/4 protein despite abundant expression of their transcripts. CONCLUSION: Our results suggest that DNA hypermethylation and transcriptional repression of a small set of ECATs, together with post-transcriptional repression of Oct3/4 and Sox2, contribute to the loss of pluripotency in male germ cells

International Perception of Competence, Education, and Training Needs Among Biomedical Professionals Involved in Medicines Development

The development of new medicines today, requires a multi-professional workforce, both in industry and the clinical research arena. Pharmaceutical physicians (PPs) and medicines development scientists (MDS) need a certain level of competence, achieved through on-the-job experience, with a postgraduate education foundation and continuous professional development programs. In order to assess the self-perception of competence, education and training needs, an on-line questionnaire based on the seven domains of competence, developed by IFAPP-PharmaTrain, was prepared and distributed among PPs and MDS members of IFAPP’s affiliated professional associations in countries with facilities for postgraduate education. The data collection was run over a fixed period of three months in Japan, Italy, Brazil, and Spain during 2017. Results indicate low but variable levels of perceived competence for the various domains as well as seniority in the job. All respondents declared a significant need for continuing professional development in all domains. These results corroborate and support the continuous efforts, put in place by IFAPP and the PharmaTrain Federation, to foster the development of accredited education and training among professionals involved in medicines development

Fostering Competence in Medicines Development: The IFAPP Perspective

IFAPP (International Federation of Associations of Pharmaceutical Physicians and Pharmaceutical Medicine) is a nonprofit organization with the mission to promote Pharmaceutical Medicine & Medicines Development (PM&MD) by enhancing the competencies and maintaining high research ethical standards of Pharmaceutical Physicians and other professionals involved in medicines development worldwide, leading to the availability and appropriate use of medicines for the benefit of patients and society(1). About 30 national professional associations related to PM&MD, involving 7000 professionals, are affiliated to IFAPP Medicines development has traditionally been a challenging enterprise, with high risk, high investment, and potentially high returns in the lengthy and complex process of identifying a new chemical entity as a candidate for development and possibly succeeding in bringing it as a pharmaceutical product to the market. However, the emergence of genomics, translational research, biomarkers, and precision medicine pose challenges going forward involving allocation of resources, price, market access, and cost-effectiveness as opposed to the traditional concepts of "efficacy" and "safety." Education and Continuing Professional Development (CPD) are a major focus of IFAPP. The International Conference on Pharmaceutical Medicine (ICPM) is the largest event for our organization; ICPM is held every 2 or 3 years and is aimed to provide the state of the art in key areas for our discipline and profession. The paper is a reflection on the role of competency-based education and training for Pharmaceutical Physicians and medicines development scientists, as was discussed during the recent ICPM 2016 held in Sao Paulo, Brazil on April 18-19, with the support of the Brazilian Association of Pharmaceutical Medicine, and gathered around 200 representatives from the pharmaceutical, clinical research and regulatory arenas from all over the world(2,3)

Body mass index >= 23 is a risk factor for insulin resistance and diabetes in Japanese people: A brief report

Background: Screening for undiagnosed type 2 diabetes mellitus is recommended for Asian Americans with a body mass index ≥23. However, the optimal body mass index cut-off score for predicting the risk of diabetes mellitus in Japanese people is not well known. The aim of this study was to determine the best body mass index cut-off score for predicting insulin resistance and diabetes mellitus in the Japanese population. Methods: This study had two parts, a clinical investigation and a retrospective observational investigation. In the clinical part of the study, 58 participants (26 with type 2 diabetes mellitus and 32 non-diabetics) underwent a hyperinsulinemic-euglycemic clamp from which their glucose disposal rate was measured. For the retrospective part of the study, medical check-up data from 88,305 people in the Tottori Prefecture were analyzed for clinical evidence of diabetes mellitus. The optimal BMI cut-off scores for prediction of insulin resistance and diabetes mellitus were determined. Results: In the clamp study, the optimal body mass index cut-off score to predict insulin resistance in non-diabetic patients was 22.7. All participants with type 2 diabetes mellitus were insulin resistant, and the optimal body mass index cut-off score for prediction of severe insulin resistance was 26.2. When the data from the type 2 diabetic and the non-diabetic participants were combined, the optimal body mass index cut-off score for prediction of insulin resistance was 23.5. Analysis of 88,305 medical check-up records yielded an optimal body mass index cut-off score for prediction of diabetes mellitus of 23.6. Conclusions: These results suggest that having a body mass index ≥23 is a risk factor for insulin resistance and diabetes mellitus in the Japanese population

CPR-IR is an insulin resistance index that is minimally affected by hepatic insulin clearance-A preliminary research

Background: Increased hepatic insulin clearance (HIC) is important in the pathophysiology of type 2 diabetes mellitus (T2DM). The aim of this study is to analyze an effective insulin resistance (IR) index that is minimally affected by HIC. Methods: Our study involved 20 participants with T2DM and 21 healthy participants without diabetes (Non-DM). Participants underwent a meal tolerance test from which plasma glucose, insulin and serum C-peptide immunoreactivity (CPR) were measured, and HOMA-IR and HIC were calculated. Participants then underwent a hyperinsulinemic-euglycemic clamp from which the glucose disposal rate (GDR) was measured. Results: The index CPR-IR = 20/(fasting CPR × fasting plasma glucose) was correlated more strongly with GDR, than was HOMA-IR, and CPR-IR could be used to estimate GDR. In T2DM participants with HIC below the median, HOMA-IR and CPR-IR were equally well correlated with GDR. In T2DM with high HIC, CPR-IR correlated with GDR while HOMA-IR did not. In Non-DM, CPR-IR and HOMA-IR were equally well correlated with GDR regardless of HIC. The mean HIC value in T2DM was significantly higher than that of Non-DM. Conclusions: CPR-IR could be a simple and effective index of insulin resistance for patients with type 2 diabetes that is minimally affected by HIC

The impact of comorbidity on the outcome of total hip replacement in Japan and the United Kingdom.

The impact of comorbidity on patient outcomes following an intervention has been largely ignored. No studies have been reported in the UK or Japan. The aim of this thesis was to assess the impact of comorbidity on the outcome of a common major surgical operation - total hip replacement. Comorbidity was measured using the Index of Co-Existent Disease developed in the USA, which reliability was assessed. Two retrospective cohorts, one in Japan and one in the UK were studied. Data were collected from patients' case notes extraction and by postal questionnaire to patients one year after surgery. After THR, patient's health status was improved in both countries and satisfaction for care was high. Significant differences in in-hospital complications were observed between Japan and the UK in terms of complication rate. type and severity, and their association with independent variables. Comorbidity was significantly associated with serious complications and with change in health status in the UK and with minor complications in Japan. A logistic regression model using the ICED and independent confounding factors suggested a significant relationship between comorbidity and complications. However, the model did not fit the data well. A multiple regression model for change in health status showed that much of the variance was explained by the preoperative health status but not by comorbidity. The low number of serious complications in Japan and the high complication rate in patients in the lowest comorbidity severity level in the UK made the predictive power weak. Finally, through the experience of this study, some recommendations for clinical practice and further research are discussed
