There are about 7997 clinical studies being (or have been) conducted in Japan. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Any platelet function tests have not been widely used in the clinical practice of acute cerebrovascular disease because of the concerns in repeatability, economic performance, and simplicity. Soluble C-type lectin-like receptor 2 (sCLEC-2) is a new marker for platelet activation, which can be easily measured by usual blood collection in routine clinical practice. We planned the sCLEC-2 in Stroke (CLECSTRO), which is a prospective cohort study in patients with acute ischemic stroke (AIS) and transient ischemic attack (TIA). We planned the sCLEC-2 in Stroke (CLECSTRO), which is a prospective cohort study in patients with acute ischemic stroke (AIS) and transient ischemic attack (TIA). The purpose of this study is to evaluate the clinical utility of sCLEC-2 as a biomarker for pathophysiology, differential diagnosis, prediction of prognosis, and monitoring of antiplatelet therapy in patients with AIS and TIA. Subjects are patients with AIS or TIA and control patients required for differentiation from AIS or TIA. The target population is 600 including the patients and the controls. The outcomes include difference in plasma sCLEC-2 level between patients with AIS or TIA and patient controls, correlation between sCLEC-2 after antithrombotic therapy and recurrence or worsening of stroke, difference in sCLEC-2/D-dimer ratio between non-cardioembolic and cardioembolic AIS or TIA, and correlation between baseline sCLEC-2 and outcome (modified Rankin scale score) after 3 months. sCLEC-2 could be a widely useful biomarker to contribute to the progress of precision medicine in clinical practice of AIS and TIA.
Prompt identification of allograft failure (AF) is highly desirable to address patients to liver retransplantation, in order to maximize results and preserve patients safety. Recently, sophisticated kinetic models became available, offering the possibility to predict 90-day AF with unprecedented accuracy, by computing data from the first 10 days after liver transplant (LT). The growing utilization of extended criteria and cardiac death donors stimulates the transplant community to further refine such predictive models and validate them on a larger scale population of patients across the nations. This study aims to develop new algorithms for the timely prediction of AF at 90 and 365 days using a prospective international cohort from high-volume centers, to validate them on a large retrospective cohort, to identify the best time for retransplantation, to stratify the risk of AF according to the graft type (i.e. DBD, ECD, DCD, LD), to weigh the effect of risk-mitigation strategies, and to assess the correlation with post-LT morbidity and mortality.
Compensated advanced chronic liver disease (cACLD) was associated with a high rate of variceal bleeding, ascites, and hepatic encephalopathy due to portal hypertension. In these patients, esophagogastroduodenoscopy and hepatic venous pressure gradient were recommended methods to evaluate portal hypertension. However, non-invasive predictors of outcomes to stratify care remains needed. Although the updated EASL guideline has recommended that patients with liver stiffness >20kPa or platelets <150*10^9/L had the high risk of decompensation, the criteria remains to be validated. This international multicenter study aims to develop a novel CHESS-SAVE score to further predict the risk of liver decompensation in cACLD patients.
Anti-neutrophil cytoplasm antibodies (ANCA) are defined as important serological markers for the diagnosis of some forms of small vessel vasculitis, including granulomatosis with polyangiitis (GPA) , microscopic polyangiitis(MPA) and to a lesser extent Churg -Strauss syndrome or Eosinophilic granulomatosis with polyangiitis (EGPA).So they are called ANCA-associated vasculitis(AAV). An international consensus statement for ANCA testing statement was issued in 2017 and states that the antigen specific immunoassays can be used for the accurate diagnosis of ANCA-associated vasculitis without the need for indirect immunofluorescence(IIF). In the present study we will test whether the antigen specific assays screening is a valuable alternative to IIF confirming with immunoassay for the diagnosis of AAV on a number of patients and controls. Aim To evaluate the performance of the recommended strategy for the detection of ANCA based on screening with antigen specific immunoassays on a number of AAV patients and relevant disease controls In Kagawa university hospital (rheumatology department). Patients and methods This is a prospective study will be conducted at the department of rheumatology in Kagawa university hospital in which consecutive samples will be included from patients suspected to have AAV; patients subsequently identified as having AAV will be included as AAV patients, while patients in which the diagnosis AAV is rejected, will be included as disease controls. PR3-and MPO-ANCA will be performed using assays from Medical & Biological Laboratories Co (Anchor CLEIA) isayama.takuya@mbl.co.jp
This study is to detect the infertile couple (women) Anti-Mullerian Hormone (AMH) profile in major subgroups such as Poly Cystic Ovarian Syndrome (PCOS), Endometriosis, etc via age intervals and ethnic difference.
This study aim is to evaluate the additional effect of eicosapentaenoic acid and dose up effect of rosuvastatin for neoatherosclerosis in coronary artery disease patients.
Background: Dynamic balance keeps the vertical projection of the center of mass within the base of support while the center of mass moves. The age-related decrease in dynamic balance is a risk factor for falls. Dynamic balance tests are used to predict the risks for falls and eventual falls but the psychometric properties of most tests assessing dynamic balance are unsatisfactory and comprise no actual loss of balance while walking. Objectives: Using beam walking distance as a measure of dynamic balance, we will determine the psychometric properties, lifespan and patient reference values, the relationship with selected 'dynamic balance tests', and the accuracy of beam walking distance to predict falls. Methods: This cross-sectional observational study will examine healthy adults in 7 decades (n=432) at 4 centers. Center 5 will examine patients (n=100) diagnosed with Parkinson's disease, multiple sclerosis, stroke, and balance disorders. At Test 1, all participants will be measured for demographics, medical history, grip and leg strength, short physical performance battery, static balance on a force platform, and dynamic balance using beam walking (4m-long, 4, 8, and 12 cm wide) under single (beam walking only) and dual task conditions (beam walking while concurrently performing an arithmetic task). In addition, cognitive function (global cognition, attention, executive function, processing speed, memory) will be assessed. Patients and healthy participants age 50+ will be additionally measured for fear of falling, history of falls, miniBESTest, functional reach on a force platform, timed up and go, and reactive balance. At Test 2, 7-10 days after Test 1, healthy adults young and age 50+ (n=40) will be re-tested for reliability of beam walking performance. All participants age 50+ will be re-called to report fear of falling and fall history 6 and 12 months after Test 1. Conclusion: The investigators expect to find that beam walking performance vis-à-vis the traditionally used balance outcomes predicts more accurately fall risks and falls.

The design of this study is multicenter randomized clinical trial, comparing oncological and surgical outcomes between mesenteric approach and conventional approach during PD for PDAC.

The main purpose of this study for patients with gastric or gastroesophageal cancer is to evaluate how well the tumor is responding to treatment with nivolumab by itself, or in combination with ipilimumab. For patients with esophageal cancer, the main purpose is to evaluate how well the tumor is responding to treatment with the combination of nivolumab and ipilimumab.
