Filter by:Acute upper gastrointestinal bleeding (UGIB) is one of the commonest medical emergencies. The condition accounts for 150 per 100,000 populations. A National United Kingdom reported a crude overall mortality rate of 10%. While bleeding stops spontaneously in majority of patients at their presentation, there remains a subgroup of patients who continue to bleed or develop recurrent bleeding. In these patients, the mortality increases manifolds. If these high-risk patients can be identified, early interventions may improve their outcomes. Several prognostic indices are in use for the purpose of patient stratification. They include the Rockall, Glasgow-Blatchford (GBS) and the Baylor scores. The Rockall score is a composite score which incorporates clinical parameters as well as findings during endoscopy which was derived to predict mortality. The GBS is a pre-endoscopy or a clinical score for the prediction for the need of further intervention loosely defined as the need for transfusion, endoscopy or surgery. It has been shown to be accurate in identifying low risk patients for early discharge.
This is a prospective cohort study investigating cardiac function and cardiac biomarkers in patients with acute Aneurysmal Subarachnoid Haemorrhage (aSAH). The aims of the study are to document the incidence of myocardial dysfunction,to find the predictive factors of myocardial dysfunction, describe heart rate variability and to assess the impact of all cardiac problems on morbidity and mortality.
Kenya is one of the countries in sub-Saharan Africa that still experience high maternal mortality. For instance, in 2008/09 maternal mortality ratio was estimated to be 488/100,000 live births. Direct obstetric complications such as puerperal sepsis, postpartum hemorrhage, pre-eclampsia and eclampsia, obstructed labor and indirect causes including HIV, malaria and anemia in pregnancy are responsible for the majority of these cases. Just under 44% of births in Kenya are delivered under the supervision of a skilled birth attendant. The overall objective of this study is to determine the effect of provider type in the occurrence and management of serious childbirth related complications among postpartum women at the community level in Bungoma and Lugari Districts of Western Province, Kenya. The proposed study will employ a case control study design in which women with obstetric complication(s)will be cases and women without obstetric complications will be controls. Controls will be sampled concurrently with the cases. Each time a new case is diagnosed, a control is selected from the population at risk in the neighborhood at that point in time. The study population will consist of women aged 15-49 years with a delivery in the past 12 months. A woman who reports having experienced a birth-related complication will be recruited as a case while woman who reports having experienced no complication during child-birth will be recruited as a control.
The purpose of this study is to investigate how dexmedetomidine affects static and dynamic autoregulation, intracranial pressure (ICP) and cerebral oxygenation in aneurysmal subarachnoid haemorrhage (SAH) patients.
This is a double-blinded, randomized, prospective placebo-controlled clinical trial to be conducted within the Mayo Clinic and the Mayo Clinic Health System. The goal of the research study is to gather information to determine whether Doxycycline is effective for the treatment of unacceptable bleeding associated with the etonogestrel subdermal implant (ESI), as compared to placebo.
Severe bleeding in the digestive system is a common symptom of many diseases. Each year, about 50,000 people end up in British hospitals because of this problem and about 5,000 of them die. The most common cause of this bleeding is stomach ulcers. In sub-Saharan Africa, schistosomiasis (parasitic worms) is responsible for about 130,000 deaths from stomach bleeding each year. From previous research in other bleeding conditions such as surgery and trauma, we know that a drug called tranexamic acid can reduce bleeding and save lives. We now want to do the HALT-IT trial to see if giving tranexamic acid can save lives and if there are any complications in people with severe bleeding from the digestive system.
The study's main objective will be to assess which effect early initiated rehabilitation has on the frequency of complications and the level of physical and cognitive functioning after aneurysmal subarachnoid hemorrhage (SAH). To this end the following aspects will be investigated: The frequency of complications (with special emphasis on pulmonary complications,thromboembolic events, cerebral vasospasm, unintended discontinuation of drains and lines) - Length of stay in hospitals and socio-economic impact - Physical and cognitive function in the early and chronic phase after SAH - Health-related quality of life and participation in society in the chronic phase
Surgery on the aorta can be associated with significant blood loss. Most commonly this is due to bleeding at the site of aortic anastomosis. Surgical bleeding is associated with significant morbidity. One way to prevent bleeding is to use a special glue (sealant) after performing large connections on the aorta. The goal of this study is to compare the different methods surgeons use to stop/prevent bleeding. The study team will collect medical information about patients before, during, and after surgery on their aortas, including the methods used to prevent bleeding. This information may help doctors improve the way that they care for these patients.
Post-partum hemorrhage (PPH) is a major cause of maternal death worldwide. Oxytocin is the most common uterotonic drug used to prevent and treat PPH in North America, however, there are some limitations to its use. Oxytocin has a very short duration of action, which requires a continuous infusion to achieve sustained uterotonic activity. The Society of Obstetricians and Gynecologists of Canada (SOGC) has recently recommended a single 100mcg dose of carbetocin at elective Cesarean delivery to promote uterine contraction and prevent post partum hemorrhage (PPH), in lieu of the more traditional oxytocin regimens. Carbetocin lasts 4 to 7 times longer than oxytocin, with a similar side effect profile and apparent greater efficacy rate. However, a dose response study to determine the minimum effective dose of carbetocin has not yet been published. The investigators hypothesize that the minimum effective dose (ED90) is at least 20mcgs (or perhaps below) in women undergoing elective Cesarean delivery.
A randomized trial aimed at determining whether or not hemoclips are effective in preventing post-polypectomy bleeds on polyps that are 10mm in size or greater.
