Filter by:With evolving endovascular technologies there is a growing debate centered on the relative safety and efficacy of the currently accepted alternatives for the treatment of ruptured cerebral aneurysms in the face of acute subarachnoid hemorrhage (SAH). The purpose of this study is to compare the safety and efficacy of microsurgical clipping and endovascular coiling of acutely ruptured cerebral aneurysms in a prospective, randomized fashion.
Low-dose aspirin (ASA) has emerged as the most important cause of peptic ulcer bleeding worldwide. In western countries, ASA has overtaken non steroidal antiinflammatory drugs (NSAIDs) as a major cause of peptic ulcer bleeding in the elderly population [1,2]. Management of peptic ulcer bleeding in patients receiving ASA for cardiothrombotic diseases is a clinical dilemma. In a randomized trial of continuous versus interrupted ASA therapy after endoscopic treatment of peptic ulcer bleeding, patients who discontinued ASA had a 10-fold increased incidence of all-cause mortality compared to those who received continuous ASA therapy. On the other hand, patients receiving continuous ASA therapy had a two-fold increased risk of early rebleeding [3]. Thus, preventing the occurrence of peptic ulcer bleeding in ASA users is important in reducing morbidity and mortality. Given the uncertain clinical utility of Helicobacter Pylori (Hp) testing in ASA users, this prospective cohort study aims to determine whether testing for Hp will have any impact on the long-term incidence of ulcer bleeding in ASA users with high ulcer risk. The investigators hypothesize that among ASA users with Hp infection and ulcer bleeding, the long-term incidence of recurrent ulcer bleeding with ASA use will be low after eradication of Hp alone.
The aim of this study is to evaluate the prophylactic effects of Ranolazine on new onset atrial fibrillation in post-operative coronary artery bypass graft and valve surgery patient population at Staten Island University hospital.
The postpartum hemorrhage (PPH) is the major complication of the delivery. In clinical practice, if after giving birth, the placenta is not expelled naturally, an active management should be triggered. Escalating therapy after obstetric maneuvers (placenta, uterus, examination of the birth canal), begins with uterotonic treatments for invasive treatments lead to embolization, vessel ligation and hysterectomy. However, the morbidity of these techniques and the desire to preserve fertility required to devise new therapeutic solutions, which have recently led to the development of an innovative medical device intrauterine hemostasis. The postpartum haemorrhage are mainly the result of weak and bleeding from the surface corresponds to the placental insertion, which is no longer localized. With the innovative medical device, our main hypothesis is that the uterine walls will append to the walls of the cup after depressurization of the latter. The actuation of the suction cup will lead to aspiration of all sides of the uterus (it is mostly the anterior and posterior that are important). The suction cup is flexible to adapt to the size of the uterus in order to be placed and removed easily from the uterine cavity.
Victims of trauma with severe head injury who have bled into their brains are at high risk of developing blood clots in their legs. These blood clots can break off and travel through the bloodstream to the lungs causing death. Blood thinners can be given to patients to prevent blood clots from developing but this can leave patients at risk for additional bleeding in the brain causing further damage or death. The earlier blood thinners are started the more effective they are at preventing blood clots but some patients with severe head injury who have bled into their brains will develop further bleeding even if they do not receive blood thinners. Even though a growing body of research has shown that the majority of bleeding in the brain stops within the first 24 hours after injury and that it is safe to start blood thinners as early as 24 hours after injury, doctors are still waiting longer than 4 days to start blood thinners in these patients over concerns of worsening bleeding. In Canada, almost half of the patients with severe head injury do not receive blood thinners until at least five days after injury. Delays in starting blood thinners appear to put patients at increased risk of developing blood clots, unnecessarily. This study will compare the benefits of starting low-molecular weight heparin (LMWH), a type of blood thinner, early (less than 48 hours) versus the current practice (waiting until the 5th day after being injured) in preventing blood clots in patients who have bled into their brains after severe head injury. The investigators believe that starting LMWH earlier will be more effective in preventing blood clots without worsening any bleeding when compared to waiting to start blood thinners. This study is called OPTTTICH (Optimal Timing of Thromboprophylaxis in Traumatic IntraCranial Haemorrhage) and will be the largest Canadian investigator-initiated randomized control trial on blood clot prevention in trauma patients with severe head injury who have bled into their brains.
Use of risk scoring systems in the assessment of patients presenting with upper gastrointestinal haemorrhage is increasing. Comparative studies have intended to identify the system of choice, but the majority of these are characterized by retrospective designs, small sample sizes, low rate of severe bleeding, or low mortality. The main aim of this study was to identify the optimal scoring system.
The purpose of this retrospective study is to test the hypothesis that uncontrolled tachycardia serves as a risk factor for adverse cardiovascular events and poor outcome after Subarachnoid Hemorrhage (SAH).
Primary objective: Evaluation of capsule endoscopy in the emergency setting of severe GI-Bleeding.
Intraventricular hemorrhage (IVH) in preterm infants is one of many devastating consequences of prematurity that have both acute and long-term sequelae. Turning a preterm infant's head to one side may increase intracranial pressure and occlude major ipsilateral veins in the neck, which could increase cerebral venous pressure and decrease cerebral venous drainage. Keeping preterm infants' heads in a slightly elevated midline position (side or supine) during the first 168 hours(HOL) has been recommended as one of the 10 potentially better practices to reduce the incidence of IVH in preterm infants. To the best of our knowledge, there has been no systematically collected clinical data quantifying the relationship between IVH and head position in preterm infants. However, the midline head position may challenge the well-known right neonatal head position preference. This preference continues until 3-6 months of age, after which preterm neonates keep their heads mainly in midline. The best head position for preterm neonates is still to be determined. Therefore, the investigators are aiming to conduct a large scale multicenter randomized control trial on order to answer the following research question: Does keeping heads of preterm infants less than 30 weeks of gestation in flat midline (FM) throughout the first 168 HOL reduce the risk of IVH compared to right flat lateral (rFL)? We hypothesized that keeping heads of preterm infants less than 30 weeks of gestation in FM throughout the first 168 HOL would reduce the risk of IVH compared to rFL.
The purpose of this trial is to determine the effective dose of carbetocin which would prevent the occurrence of postpartum uterine atony in 90% of women undergoing an elective cesarean delivery.
