All clinical trials

Data reported by the international registry of acute aortic dissection (IRAD) in not sufficient to reflect clinical characteristics of acute aortic dissection in China. Moreover, clinical characteristics of Acute aortic dissection have not evaluated to data. The aim of this study is analyze changing trend of clinical characteristics of Chinese patients with acute aortic dissection.

Using an adaptive optics imaging device, retinal structures are observed in healthy and diseased subjects.

Collect the real clinical background of advanced colorectal cancer c of China.

The purpose of this study is to find out if we can predict the progress of acute upper respiratory tract infection to acute bacterial rhinosinusitis in Finnish conscripts by symptoms, clinical, endoscopic or radiological findings, middle meatal swab samples or nitric oxide measurement.

Corneal diseases are a major cause of blindness worldwide, and corneal infections are a substantial cause of blindness in Asia. The aim of the Asia Cornea Society Infectious Keratitis Study (ACSIKS) is to study infectious keratitis (corneal infections) in Asian countries, so as to improve strategies for prevention and treatment, and to reduce the burden of blindness in Asia. The first phase of ACSIKS is an 18-month observational study involving 11 eye hospitals in 8 Asian countries; these hospitals manage more than 6700 cases of corneal infections every year. From the first quarter of 2012, all patients with a corneal infection will be recruited and a standard ACSIKS protocol will be applied; this protocol includes the use of a common set of study forms and a suggested panel of microbiological examinations. However, each centre will be continue to treat their patients with the anti-infective therapy standard for their centre. Data will be recorded for each patient for a period of six months, including their medical and surgical management, the final clinical outcome and vision. Bacterial and fungal growths from patients will also be stored for further research during a second phase of ACSIKS. These studies will focus on evaluating the resistance of the most common bacterial infections to the current available antibiotics, performing DNA testing to compare our strains with bacterial infections in the West, and to developing new diagnostic tests and anti-infective therapies tailored to corneal infections in Asia.

Previous cross-sectional studies have demonstrated that blood pressure (BP) measurements at home (HBP) in the morning offer stronger predictive power for micro- and macrovascular complications in patients with type 1 and 2 diabetes than casual/clinic blood pressure measurements (CBP) (Kamoi K et al, 2002-2003). Further, a prospective, longitudinal study for 6 years in patients with type 2 diabetes also demonstrated that control of wakening-up HBP provides the stronger predictive power for the outcomes than that of CBP did (Kamoi et al, 2010). However, it is not clear to show which of BP measurement provides the stronger predictive power for outcomes by comparing cumulative events over a longer time than 6 years. Therefore, the investigators examined which of HBP or CBP provides the stronger predictive power for outcomes in addition of renal anemia reported previously over 10 years in the patients with type 2 diabetes.

The Parkinson's Genetic Research Study (PaGeR), headed by Dr. Cyrus Zabetian, is searching for genes that increase the risk of developing Parkinson's disease (PD) and related disorders. The study is a joint effort by neurologists and researchers across the United States and is sponsored by the National Institutes of Health. The coordinating center for PaGeR is located at the University of Washington and the VA Puget Sound Health Care System in Seattle.

The objective of this study is to use a DEK ELISA to quantitatively measure DEK protein in the urine of patients suspected of having bladder cancer. The measurement of urine DEK protein, relative to an established cut-off, is correlated with the presence or absence of bladder cancer.

Patients who have scheduled a gastric bypass (RYGB) in UZ Leuven, will be questioned preoperatively and one, three, six and twelve months after gastric bypass surgery. The purpose of this study is to explore current practice regarding the use of medication and medication counseling after RYGB and to examine the changes in dietary pattern before and after RYGB.

The purpose of this study is to measure prothrombin time (PT) on an experimental device and a commercially available device on persons receiving coumadin (warfarin)treatment.
