KNOW-CKD (KoreaN cohort study for Outcome in patients With Chronic Kidney Disease) is a nation-wide, ten-year longitudinal cohort study, launched in 2011. The aim of the study is to assess the characteristics and risk factors of progression and complications of CKD of Korea. Pediatric sub-cohort of KNOW-CKD is planned to enroll 450 children with CKD, stage I to V (pre-dialysis).

The goal of this study is to compare the characteristics of echocardiography and different monitoring devices in shock patients, the relationship of device parameters to biomarkers associated with shock, and determine if these any of these add clinical utility when predicting the cause of shock. We will perform a prospective, observational study of patients found to have shock physiology in the ED and follow them to determine the final shock category and ultimate outcomes.

The purpose of this study is to characterize the circadian rhythm disruption experienced by patients as determined by plasma melatonin, cortisol, and other circadian analytes

Stress hyperglycaemia is commonly observed during hospitalization in the intensive care unit (ICU) and has been shown to adversely influence outcome. It has been hypothesized that, when it occurs in previously non-diabetic patients, it reflects a latent disturbance of the glucose metabolism. Assessing the incidence of this phenomenon and identifying its risk factors could support prevention, detection and early treatment of impending diabetes mellitus type 2. We will perform a glucose tolerance test approximately 6-9 months post-ICU admission to screen for disorders of glucose metabolism. Furthermore, we examined characteristics that could have predicted the post-discharge disturbances: patient characteristics, parameters of disease severity and of glucose metabolism, as well as the FINDRISC (Finnish Diabetes Risc Score). We plan to enroll 400 patients.

Laryngeal cancer is common in the Taiwanese populations. Before early 80's, open laryngectomy was the suggested treatment modality for laryngeal cancer. Patients of laryngectomy lost speech and should communicate by using prosthesis. So after 90's, medical organ preservation by chemoradiation therapy took the place of operation. Unfortunately, from the recent review, five-year survival rate was decreasing and is even lower than that reported 10 years ago. In 1983-1985 it was 68.1% but decreased to 64.7% in 1992-1999. It is the only cancer type of decreasing survival in 24 index cancers. Laser resection of laryngeal tumor was first reported by Jako and Strong and widely used in the Europe. Dr Steiner and his colleagues developed a non-en block resection technique made microscopic resection more easily and would not be limited by tumor location or size so much. The investigators used transoral microscopic laser (TLM) in early glottic cancer and reported five-year overall survival as 97%. TLM five-year disease control rate was reported as 85%. There are some reports about TLM in advanced stage laryngeal cancer and overall 5-year survival rate can be achieved as high as 55%. Present project is planning to develop a comprehensive organ preservation protocol based on microinvasive TLM as primary treatment modality for early glottic cancer without neck or distant metastasis. The objects of the project are as followed. Long term outcomes by performing the treatment protocol. The outcome measurements include local control rate, overall and disease specific survival, larynx preservation rate. The difference between surgical samples and pretreatment imaging examination. The role of adjuvant therapy. Management and follow-up in neck metastasis. Searching for risk factors and predictor factors. Adequate salvage treatments in local or regional recurrence. Realizing failure patterns and appropriate follow-up protocol according to it.

The major purpose of this study is to evaluate a laboratory developed test that measures multiple breast cancer-specific biomarker proteins in your blood samples. The biomarker results along with your personal medical profile will be evaluated to determine your risk for the presence of a malignancy in the breast as compared to your breast evaluation assessment conducted by your physician.

The rate of cognitive decline due to ageing is increased 1.5-fold to 2.0-fold in individuals with type 2 diabetes.There are no established specific treatment measures to prevent or ameliorate cognitive impairments in patients with diabetes. we want to detecte early clinical dementia in diabete.

Congenital solitary kidney (CSK) is a disorder caused by an abnormal development of one of the two kidneys. The reported incidence ranges between 1:450-3200. It is debated whether CSK is a benign condition or not. A variable risk of developing proteinuria (11-27%), hypertension (0-60%) and chronic kidney damage (3.5-30%) is described. This knowledge derives mainly from retrospective studies performed in tertiary medical centers which is difficult to compare for the following reasons: the number of individuals evaluated, the length of follow-up and the outcome studied. The aim of this longitudinal study is to assess, in a cohort of children with congenital solitary kidney, during a 10 year follow-up period: 1) the rates of developing proteinuria, hypertension and chronic kidney disease and the corresponding potential prognostic factors. 2) the role of new biomarkers of glomerular (Cystatin C) or tubular damage (NGAL, NAG, B2-microglobulin) in predicting the appearance of chronic kidney damage.

The purpose of this study is to assess fusion status in patients who underwent spinal fusion with Actifuse synthetic bone graft versus other bone graft material (including autograft) in achieving lumbar spinal fusion.

The BAP1 trial will examine the blood of patients diagnosed with choroidal nevi or uveal melanoma for a germline BAP1 mutation and other genetic markers associated with developing malignancy as well as additional sequencing of the uveal melanoma genome.
