Hide Abstract
We constructed a simulation model with a geographic information system (GIS) to predict the future shortage of beds in the Tokyo Metropolitan Area. With a grid square method, we calculated patient numbers for every 500 square meters of the Tokyo Metropolitan Area until 2040 and estimated whether those in need could be admitted to hospitals within an hour's drive from their homes. The simulation demonstrates that after 2025 many patients may not be able to find hospitals within this time framework. The situation will be especially serious in the center of Tokyo and along the railway lines, where many senior citizens reside. We can now apply this innovative GIS method in many fields and especially for the precise estimation of future demands for and supply of medical assistance.

More than 10 years ago Haux et al. tried to answer the question how health care provision will look like in the year 2013. A follow-up workshop was held in Braunschweig, Germany, for 2 days in May, 2013, with 20 invited international experts in biomedical and health informatics. Among other things it had the objectives to discuss the suggested goals and measures of 2002 and how priorities on MI research in this context should be set from the viewpoint of today. The goals from 2002 are now as up-to-date as they were then. The experts stated that the three goals: "patient-centred recording and use of medical data for cooperative care"; "process-integrated decision support through current medical knowledge" and "comprehensive use of patient data for research and health care reporting" have not been reached yet and are still relevant. A new goal for ICT in health care should be the support of patient centred personalized (individual) medicine. MI as an academic discipline carries out research concerning tools that support health care professionals in their work. This research should be carried out without the pressure that it should lead to systems that are immediately and directly accepted in practice.

Hide Abstract
Health care and information technology in health care is advancing at tremendous speed. We analysed whether the prognoses by Haux et al. - first presented in 2000 and published in 2002 - have been fulfilled in 2013 and which might be the reasons for match or mismatch. Twenty international experts in biomedical and health informatics met in May 2013 in a workshop to discuss match or mismatch of each of the 71 prognoses. After this meeting a web-based survey among workshop participants took place. Thirty-three prognoses were assessed matching; they reflect e.g. that there is good progress in storing patient data electronically in health care institutions. Twenty-three prognoses were assessed mismatching; they reflect e.g. that telemedicine and home monitoring as well as electronic exchange of patient data between institutions is not established as widespread as expected. Fifteen prognoses were assessed neither matching nor mismatching. ICT tools have considerably influenced health care in the last decade, but in many cases not as far as it was expected by Haux et al. in 2002. In most cases this is not a matter of the availability of technical solutions but of organizational and ethical issues. We need innovative and modern information system architectures which support multiple use of data for patient care as well as for research and reporting and which are able to integrate data from home monitoring into a patient centered health record. Since innovative technology is available the efficient and wide-spread use in health care has to be enabled by systematic information management.

Hide Abstract
Abstract Objective. Anti-ribosomal P protein antibody (anti-P) is detected in a fraction of systemic lupus erythematosus (SLE) patients, especially with lupus psychosis, lupus nephritis, and lupus hepatitis. However, it has been unclear whether anti-P testing is specific for SLE. The current studies were designed to examine the efficacy of serum anti-P testing in diagnosis of SLE. Method. Multicenter retrospective study was performed with 102 SLE patients, 102 patients with non-SLE rheumatic diseases, and 100 normal healthy subjects, who gave informed consents. The diagnosis of SLE was confirmed according to the 1982 ACR revised criteria. Serum IgG anti-P was determined by ELISA using the C-terminal 22 amino-acids of ribosomal P protein conjugated to human serum albumin. The specificity and sensitivity of anti-P were compared with those of anti-DNA, anti-Sm, and anti-cardiolipin (CL) antibodies. Results. Serum anti-P was positive in 38 of 102 SLE patients (37.3%), in 4 of 102 patients with non-SLE rheumatic diseases (3.9%), and in none of 100 normal subjects. Receiver operating characteristic (ROC) curve analysis revealed that anti-P provided higher AUC (area under the curve) than anti-Sm or anti-CL. Consistently, the sensitivity of anti-P (37.3%) was superior to that of anti-Sm (27.5%) and anti-CL (24.5%), but inferior to that of anti-DNA (51.0%), whereas the specificity of anti-P (96.1%) was superior to that of anti-CL (86.3%) and comparable to that of anti-DNA (96.1%) and anti-Sm (96.1%). Conclusion. These results indicate that serum anti-P testing might be an effective measure in diagnosing SLE, providing better diagnostic efficiency than anti-Sm and anti-CL.

Hide Abstract
Introduction. This study aimed to investigate the efficacy of abatacept for arthritis in patients with rhupus, an overlap syndrome between rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Methods. Patients who fulfilled both the 2010 ACR/EULAR criteria for RA classification and the 1997 ACR revised criteria for classification of SLE and received abatacept treatment for arthritis were retrospectively studied. Results. Six rhupus patients who fulfilled the inclusion criteria above were identified. All patients had active arthritis despite receiving antirheumatic drugs including methotrexate when abatacept was initiated. Clinical Disease Activity Index (CDAI) significantly decreased between baseline and 12 weeks (P = 0.028) and remained low through 24 weeks. All patients achieved either a good or moderate response according to the EULAR response criteria at 24 weeks. Health Assessment Questionnaire-Disability Index (HAQ-DI) also significantly decreased between baseline and 24 weeks (P = 0.043). In addition, the levels of immunoglobulin G and anti-DNA antibody significantly decreased between baseline and 24 weeks (P = 0.028 and P = 0.043, resp.). Conclusions. Treatment with abatacept is likely to be efficacious in patients with rhupus whose arthritis is refractory to methotrexate. In addition, abatacept may have a moderate effect on abnormal antibody production in rhupus patients.

Hide Abstract
We started a multi-year project to collect discharge summaries from multiple hospitals and create a big text database to build a common document vector space, and develop various applications such as the autoselection of the disease. As the first step, we extracted discharge summary from two hospitals. Using a text mining method, we carried out a DPC selection. There was a difference in term structure and number of terms between the discharge summaries from both hospitals. Nevertheless, the selection rate of the disease is resembled closely.

We have to create a new paradigm for home medical care system towards a historical increase of elderly population in Japan. Tokyo University and Chiba University have been collaborating to erect a home medical care support center in Kashiwa, Chiba prefecture. We have been constructing a support center as well as a home care doctor system, and also created a teaching course for GPs to learn a home care doctor activity. We have also been constructing a regional network system called IT Net in Chiba, which connects all the entire medical and care staff. We will expand this model in many places and to instruct medical students and residents there in the near future.

Hide Abstract
The prevalence of electronic medical record in Japan varies according to the size of the hospital which is 62.5% in major hospitals, 21.7% in medium, 9.1% in small size hospitals, and 16.5% in clinics. The complete paperless system is very limited, though some major hospitals are aiming at this system. Several regional network systems which connect different platforms of EMRs, have been developing in many districts, while the final picture of a regional network has not been clearly proposed. To develop a whole electronic health record or personal health records system from the regional network data, we have several obstacles to overcome such as standardization, a privacy act, unique national health number.

Recently, electronic medical record (EMR) systems have become popular in Japan, and number of discharge summaries is stored electronically, though they have not been reutilized yet. We performed text mining with Tf-idf method and morphological analysis in the discharge summaries from three Hospitals (Chiba University Hospital, St. Lukes International Hospital and Saga University Hospital). We showed differences in the styles of summaries, between hospitals, while the rate of properly classified DPC (Diagnosis Procedure Combination) codes were almost the same. Beyond different styles of the discharge summaries, text mining method could obtain proper extracts of proper DPC codes. Improvement was observed by using integrated model data between the hospitals. It seemed that huge database which contains the data of many hospitals can improve the precision of text mining.

Hide Abstract
Systemic lupus erythematosus (SLE) is a multisystem, autoimmune, connective-tissue disorder with a broad range of clinical presentations. SLE predominantly affects women, especially from ethnic groups with African and Asian ancestry. This disorder is a chronic illness that can be life threatening when major organs are affected, but more commonly results in debilitating condition and affects employment and fertility. This article summarizes the recent advances in our understanding of the genetics, epidemiology and pathogenesis of SLE. In addition, progress in the assessment and management of serious complications such as lupus nephritis and CNS lupus is reviewed. New therapeutic approaches, such as low-dose cyclophosphamide regimens, mycophenolate mofetil and biological agents are also discussed.

Hide Abstract
Due to the rapidly increasing super-aging society, medical policy in Japan should be redefined. Therefore, the medical and nursing home care system should now be revised greatly. We need to change the current principle that is based on cure only. The patients should receive hospitable care closely connected with their life in their home-town(region)throughout their lifetime. This is termed as "home medical care system". Here, we promote patient-centered medical home care, which implements the chronic and/or End-Of-Life care models, in Kashiwa city, Chiba prefecture. This system is a promising framework for primary care transformation. There is a need for a multidisciplinary team-based care system using information and communication technology(ICT)with smooth and seamless cooperation. However, increased awareness among the workers engaged in home medical care is first required.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
