Filter by:Leptospirosis is a worldwide zoonosis. The mortality of the disease is between 3,6% to 13%, and up to 48% for the severe leptospirosis. Only few studies exist on severe leptospirosis and none major multicentre on leptospirosis in intensive care units in Europe. The investigators conduct a retrospective multi centric study in metropolitan France in order to identify the characteristic, the treatments and the prognostic factors associated with mortality of sever leptospirosis.
This trial aims to assess safety and efficacy of three-row circular staplers compared to two-row surgical stapllers in short-term and long-term perspective in patients with rectal cancer undergoing low anterior resection with stapled colorectal anastomosis. All the patients will undergo a low anterior resection. In a half of patients a colorectal anastomosis will be created with a three-row surgical circular stapler. In another half of patients a colorectal anastomosis will be created with a two-row surgical circular stapler.
The primary objective of this multicentric observational study is to define the role of intraoperative temperature decrease (defined as reduction of at least 1 ° C during surgery) as haemorrhagic risk factor, evaluated as reduction of at least 1 gr / dl of hemoglobin, and to correlate it with the need for transfusion. Secondary objectives are infections and complications affecting other organs and systems incidence in the first week after surgery.
This study aims to determine when during gestation oxytocin receptor (OXTR) expression increases in the myometrium, which will contribute new insight to the management of obstetric hemorrhage and our understanding of normal and abnormal labor.
Anti-Mullerian hormone (AMH) is a marker for ovarian reserve. There are many studies about AMH changes in ovarian surgery, but little is known for other surgeries. We seek to investigate the hormone variations before and after uterine artey ligation for postpartum hemorrage (PPH)
Primary Aim: To determine if apixaban is superior to aspirin for prevention of the composite outcome of any stroke (hemorrhagic or ischemic) or death from any cause in patients with recent ICH and atrial fibrillation (AF). Secondary Aim: To determine if apixaban, compared with aspirin, results in better functional outcomes as measured by the modified Rankin Scale.
In this study, investigators look at a different type of technology that might help to avoid having to perform CT scans in certain patients suspected of having a head injury. Near-infrared spectroscopy (NIRS) uses a specific light wavelength to determine if there is bleeding into the head as a result of trauma. Investigators will study NIRS, using a device called the Infrascanner model 2000, to determine if it is as good at detecting bleeding in the head as CT scan, which is the current gold standard. Investigators will try to determine if NIRS can rule in or rule out bleeding into the head, and perhaps this can help to avoid subjecting these youth to the potentially harmful effects of radiation. Investigators will also study how easy it is to use NIRS so that it might become a standard part of the workup for children with suspected head injury.
Postpartum hemorrhage remains a leading cause of maternal morbidity and mortality worldwide, even in high income countries. Uterine atony is estimated to cause 70-80% of postpartum hemorrhage. Prolonged labor and augmented labor are known risk factors for postpartum hemorrhage. In attempts to reduce the incidence of postpartum hemorrhage, particularly in patients with known risks factors, it is essential to optimize preventative practices in order to reduce the rates postpartum hemorrhage. Although oxytocin is considered the first line therapy for preventing and treating uterine atony, early consideration of additional prophylactic uterotonic agents may be indicated in women with prior oxytocin exposure given oxytocin receptor desensitization and down regulation. As such, investigators sought to examine whether multimodal prophylactic uterotonics (standard oxytocin + methylergonovine), in patients who are increased risk of developing postpartum hemorrhage (specifically laboring patients who ultimately require a cesarean section) would benefit from the addition of prophylactic uterotonics. The clinical rational for administration of multimodal prophylactic uterotonics at the time of cesarean delivery in laboring patients is three-fold: to decrease the incidence of uterine atony, to decrease the incidence of postpartum hemorrhage, decrease the number of uterotonics required at the time of cesarean section. The primary outcome will be to evaluate the need for additional uterotonic agents (Methylergonovine, Carboprost, Misoprostol) at the time of delivery. Secondary outcomes will include the incidence of postpartum hemorrhage (quantitative blood loss >1 liter), surgical assessment of uterine tone four minutes following delivery of the placenta, preoperative and postoperative hemoglobin, the need for a blood transfusion, intensive care unit admission, uterine infection (endometritis).
The aim of this study is to develop a coagulation algorithm based on Quantra POCT for the treatment of coagulopathic cardiac surgery patients.
This study was designed to explore the influencing factors of spontaneous intraparenchymal hemorrhage's prognosis and develop predictive models for poor prognosis by establishing a cohort of spontaneous intraparenchymal hemorrhage (including both of the supratentorial intracerebral hemorrhage and cerebellar hemorrhage), and analyzing the correlation between collected variables and patients' outcomes.
