All clinical trials

As a result of increasing adoption of health information systems in hospitals, more and more health records can be gathered and accumulated in the healthcare data repository. For this reason, the opportunity of analyzing and mining the healthcare data for quality improvement is increasing and becoming more and more important. The purpose of the project is to gather the clinical data relevant to liver cancer, and adopt the knowledge discovery and mining modules in information technology (IT) for analyzing and discovering the knowledge from the gathered clinical data. We can analyze the gathered clinical data for comparing the outcomes of different treatment strategies, finding out new diagnosis and staging criteria and factors, and other hidden knowledge included in the clinical data. Afterwards, the discovered results and the mining algorithms can be shared though the sharable knowledge mining platform provided by our project.

Rheumatoid arthritis (RA) is an autoimmune disease of unknown etiology characterized by peripheral polyarthritis, symmetric, which leads to joint destruction and deformity. It is estimated that the RA reaches about 0.5% of the population. According to data from DATASUS, was responsible for 26,671 hospitalizations, 229 deaths and cost exceeding R$ 20 million in 2005-2007. The main bodily changes are related to joint problems, however, systemic manifestations are also found in organs such as lung and heart. Although cardiovascular diseases are the most responsible of the deaths AR, pulmonary complications are common and account for 10% to 15% of all mortality. Anaya and colleagues point out that the pulmonary involvement contributes significant morbidity and mortality in these patients. Although pulmonary involvement is a frequent manifestation in RA, the prevalence and nature of rheumatoid lung disease has not yet been precisely established. Several lung disorders such as interstitial pulmonary fibrosis, pulmonary nodules and bronchiolitis may ocorrer1. Laitinen et al point out that studies of lung function appear to be a valuable helper for radiography in the evaluation of pulmonary involvement in connective tissue diseases. Previous studies indicate that patients with RA have an increased incidence of abnormal lung function, according to assessments including spirometry, lung volume tests and diffusion capacity of carbon monoxide. Thus, the main objective of this study is to analyze the respiratory mechanics of patients with RA. Specific objectives were to seek to understand whether a relationship exists between duration of rheumatoid disease and lung function in these patients. For this, the investigators used 18 subjects in the control group, free of pulmonary disease and / or heart, all nonsmokers. In the RA group, a total of 72 patients divided into 4 groups of 18 volunteers each, classified according to disease duration (0-5 years, 6-10 years, 11-15 years and> or = 16 years). It is noteworthy that all patients in the RA group will also be non-smokers, since it is already known in the literature that smoking impairs lung function. All individuals will perform the function test with a trained technician and qualified to function. The examinations will be conducted: Forced oscillation technique and spirometry, in that order.

Abdominal wall incisional hernia is a common finding in patients who have undergone previous intra-abdominal surgeries. Common methods of abdominal fascial closure include primary closure, mesh inlay versus onlay, with or without component separation. All these methods have been shown to have recurrence rates for hernia between 3%-60% in the literature. The study describes the investigators innovative and preferred method for reconstruction of the abdominal wall as BARS (bony anchoring reinforcement system). This method manages the abdominal fascial integrity to reduce the recurrence of incisional hernia while providing an aesthetically superior abdominal wall contour.

The purpose of this study is to monitor the renal function of patients who have an antibiotic laden spacer in place to treat an infected hip or knee arthroplasty.

To validate the capability of non-invasive bio-image tests in prediction of significant coronary stenosis of symptomatic adults.

In this study we will try to show that performing Doppler of the Spiral arteries is doable. No outcome will be followed at this stage

The purpose of this study is to provide new knowledge about: Integration of rehabilitation in a highly specialized gynaecological department. Development and testing of an individually adapted rehabilitation process. Needs for rehabilitation among women with gynaecological cancer. Connection between adult attachment style for women with gynaecological cancer and their quality of life, rehabilitation needs and symptoms of depression /PTSD.

The purpose of this study is to characterize the behavior of cardiac patients with Mood Disorders and its clinical course, interpreting the results from a theoretical framework of Chaos Theory and Complexity Theory and Systems as well.

Objective: To evaluate and compare the outcome predictive power of Acute Physiologic and Chronic Health Evaluation (APACHE) Ⅳ、Ⅲ、Ⅱ scoring systems for intensive ill patients in an independent medical intensive care unit (MICU), and explore the best time point when they can most accurately predict outcome. Design: Retrospective analysis of medical records. Methods and Materials: Collect data of patients admitted between July 2010 and July 2013 to the medical intensive care unit of the First Affiliated Hospital of Sun Yat-sen University in Guangzhou, China. Patients with an ICU stay less than 4 hours and age less than 16 years were excluded. Calculate the APACHE Ⅳ、Ⅲ、Ⅱ scores and corresponding predictive mortality risks in the first 24 hours of ICU admission and the 3th, 5th, 7th, 14th, 21 th, 28th day or the day of transferred out of ICU or death. The predictive power of each model was assessed through the ratio of observed death rates and predictive death rates (Standardized mortality ratios, SMR), the calibration of observed and predictive death rates and the discriminative ability between survivors and non-survivors. Hosmer-Lemeshow test was employed for assessing the calibration and the discriminative ability was assessed by the area under the receiver operating curve. Compare the predictive power of the three models at different time points and explore the the best time point when they can most accurately predict outcome.

Left ventricular filling pressure (LVFP) has prognostic significance in patients with heart failure. Traditionally, it should be assessed by invasive method, as cardiac catheterization and Swan-Gung catheter. In advance of new techniques and modality, echocardiography provides some useful parameters for assessing LVFP, such myocardial tissue Doppler imaging. Many articles had documented that peak velocity of early-diastolic trans-mitral inflow velocity divided by early-diastolic velocity over mitral annulus correlated closely to LVFP. However, myocardial tissue Doppler only provides the information of regional myocardium, so patients with regional wall motion abnormality, as coronary artery disease, can't be assessed by this method without handicap. In addition, conduction disturbance, like bundle branch block, also influences the result of myocardial tissue Doppler. For resolving those problems, the investigators had designed a new global parameter to assess LVFP. In the investigators prior study, left atrial distensibility correlated logarithmically to LVFP in patients with severe mitral regurgitation and also in patients with acute myocardial infarction. Left atrial distensibility provided a new viewpoint to assess left ventricular diastolic function and to predict prognosis. This time, to extend left atrial distensibility to general population received echocardiographic examination for predicting prognosis is attempted.
