Warfarin is a commonly used blood thinner to treat and prevent blood clots. It is important to take the right dose of warfarin because too much can increase the risk of bleeding and too little can increase the risk of blood clots. This is why patients are closely monitored especially when they begin warfarin therapy. When clinicians prescribe warfarin, they have to consider different factors such as patient's age, body size, diet, and other medications that can interact with warfarin. Certain genes have also been found to affect warfarin dose. Individuals have variations in these genes, which can help explain why some patients need higher dose and others require less. These factors have been used to better predict a patient's warfarin dose requirement. However, these predictions were created based on Caucasian populations and they may not be accurate in predicting a safe warfarin dose if a patient is not Caucasian. This study aims to identify new genetic variation that affects warfarin dosing in Hispanic and Latino populations and try to better predict a Hispanic or Latino patient's warfarin dose requirement.
The purpose of the study is to evaluate the efficacy of Rifaximin in the treatment of cirrhotic gastroesophageal variceal bleeding.
A Prospective Multicenter Randomized Interventional Study. Blood transfusion can be lifesaving in extreme circumstances, in the absence of life threatening hemorrhage, the indications for transfusion are somewhat controversial. The aim of the current study is to determine whether a"liberal" strategy of maintaining Hb concentrations above 9 g/dL would result in a different neurological outcome when compared to a "restrictive" approach to red-cell transfusion to avoid hemoglobin concentrations < 7 g/dL in critically ill anemic patients (i.e. Hb< 9 g/dL) with acute brain injury.
1. To describe the average labor curve and establish new labor progression standards. 2. Cesarean section rates: Based on big data, the investigator will introduce the international advanced Robson class method and identify the appropriate level of cesarean section rate for each type population. 3. Establishment of "Chinese maternal-fetal medical collaboration network" and APP to promote natural childbirth.
The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.
The registry is the main objective exhaustive list of cases validated stroke brain on a geographical area defined to calculate an incidence.
This prospective, observational study aim to identify : - Prognostic factor of patients with subarachnoid haemorrhage in neuro intensive care unit - The impact of standard therapeutic used (surgery, embolization ; medical treatment of vasospasm ; treatment of complications like hyponatremia, stress myocardiopathy, …)
Patients with intracerebral aneurysm will be screened for sleep apnea using out of center polysomnography/polygraphy. Baseline blood pressure and medication will be assessed. Patients will be followed for up to 5 years to examine the increase in aneurysm size, rupture rate and changes in medication.
The primary specific aim is to perform a randomized controlled trial (RCT) to compare rates of delayed hemorrhage after DEP detection of arterial blood flow and focal treatment in PPIU's (treatment arm) with standard treatment using medical guidelines alone (controls) for prevention of delayed bleeding in high risk patients (on anti-coagulants or anti-platelet drugs or with large ulcers) after snare resection of benign colon polyps.
