Filter by:This study was conducted to compare the effectiveness of care based on the "Accelerated Recovery After Surgery (ERAS) Protocol" and the traditional method in bariatric surgery and demonstrate the difference the two methods based on evidence.
Investigators are building an empirical evidence base for real world data through large-scale replication of randomized controlled trials. The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.
Depersonalized multi-centered registry initiated to analyze dynamics of non-infectious diseases after SARS-CoV-2 infection in population of Eurasian adult patients.
Comparison of COVID-19 disease course in hospitalized patients infected by SARS-CoV-2 in first and second waves of the novel coronavirus infection
Study investigators will examine the absorption characteristics of apixaban, a direct-acting oral anticoagulation, in patients who have underwent a particular kind of surgery (pancreaticoduodenectomy) which involves resection of the duodenum.
To date, the investigators have successfully employed a radiotracer (18F-sodium fluoride) as a marker of necrotic inflammation in human atherosclerosis. The investigators aim to further the mechanistic understanding of atherothrombosis by studying the activation of glycoprotein IIb/IIIa receptors in cardiovascular thrombus using the novel platelet radiotracer (18F-GP1). Binding of 18F-GP1 to activated platelets in venous and arterial thrombi has already been demonstrated in pre-clinical studies and a phase 1 trial in man. If successful, this study would define the role of the glycoprotein IIb/IIIa receptor within in vivo thrombosis across a range of cardiovascular diseases.
The study is designed as a prospective comparative study. All patients will receive prophylactic anticoagulation according to routine hospital protocol after surgery. A bedside ultrasound examination will be performed by a trained anesthesiologist prior to the surgery and then daily beginning on postoperative day 2 until patient discharge.
Warfarin is an anticoagulant medication that is highly effective at preventing clotting disorders but which has a narrow therapeutic window. If warfarin is under effective patients are at risk of stroke, if it is over effective patients are at risk of bleeding complications. Physicians routinely and regularly measure a blood test (called the "INR") that determines the effectiveness of warfarin and have a range of test values (the "therapeutic range") in which they try to keep the patient. By convention warfarin is taken at dinnertime, however this is the same time of day that highly variable consumption of dietary vitamin K occurs (found largely in green leafy vegetables) and vitamin K alters the effectiveness of warfarin. Given vitamin K has a very short half-life (i.e. it is only active for a short period of time after it is ingested) it may make more sense to take warfarin in the morning (when very little vitamin K is ingested) to produce a more consistent drug effect. The purpose of this study is to determine whether switching current warfarin users from evening to morning dosing decreases time spent outside the therapeutic INR range.
Emergency Medicine (EM) Residents routinely conduct bedside ultrasound exams in the Emergency Department (ED) employing the two point compression method. This study endeavors to investigate the accuracy and utility of bedside ultrasound for Deep Vein Thrombosis (DVT) in the ED by EM Residents by comparing the results of that exam against the gold standard of a DVT ultrasound performed in the Radiology Department and interpreted by a Radiologist.
The goal of this study is to prevent blood clots from forming during surgery and a few days after total knee replacement surgery. This study will help us identify whether using a blood thinner in the operating room will stop blood clots from forming during the operation.
