Filter by:Portal hypertension (PH) is a common complication of chronic liver disease and a major cause of morbidity and mortality in cirrhotic patients. One of the most serious complications of liver cirrhosis is esophageal varices (EV) bleeding. The hepatic venous pressure gradient (HVPG) is the gold standard for detecting portal hypertension and its complications. Furthermore, HVPG is the most reliable method for assessing the efficacy of treatment with nonselective -blockers (NSBB), which is the preferred therapy in patients with EV who are at high risk of bleeding (HRV) and as a secondary prophylaxis in the prevention of rebleed. However, the HVPG is an invasive method that is not widely used and necessitates specialized skills. For these reasons, clinical research over the last decade has been focused on identifying non-invasive tests (NITs) capable of evaluating the PH degree and its changes. The most investigated non-invasive tests are liver and splenic stiffness measurement. In advanced cirrhosis, the increase in portal pressure is less dependent on intrahepatic resistance to portal flow due to fibrosis progression and more dependent on extra-hepatic factors such as hyperdynamic circulation and splanchnic vasodilation hence correlation between LSM and PH decreases for HVPG values higher than 12 mmHg.
The aim of our study is to determine whether the use of a tourniquet during TKA would affect total measured blood loss , operation time, postoperative complications; hemoglobin concentration; limb swelling and postoperative pain.
The objective of this study is to evaluate the hemostatic capacity of two types of collagen hemostatic sponges in nail surgery. It is a randomized triple-blind clinical trial with two experimental groups (medium porosity collagen and high porosity collagen) and control group ( non collagen).
This is a feasibility study trial to determine whether hyperacute (≤8 hour) mechanical Minimal Invasive Surgical (MIS) management is feasible and secondarily improves outcome in patients with spontaneous supratentorial intracranial hemorrhage (ICH). Patients meeting the inclusion and exclusion criteria, will be enrolled and randomized to either minimally invasive hematoma evacuation (MIS) or best medical management alone (MM). Subjects will be randomly assigned by a central web-based system in a 3:1 manner to treatment with MIS or MM. Data for each subject will be collected at the time of enrollment and treatment, and at subsequent follow-up visits.
Postpartum hemorrhage is the leading cause of maternal morbidity and mortality throughout the world. Rapid diagnosis and early management improve maternal prognosis. Postpartum hemorrhage is defined by a blood loss exceeding 500 ml during the 24 h after delivery. There are many causes of postpartum hemorrhage. Most cases develop from uterine atony, which accounts for 75% of cases. Even though there are risk factors for postpartum hemorrhage, it is still an unpredictable obstetric emergency. Coagulation plays an important role in postpartum hemostasis. Primary and especially secondary coagulation disorders are risk factors for Postpartum hemorrhage. When bleeding occurs, the decrease in fibrinogen levels is the most rapid change observed among markers of coagulation. Recent studies show that fibrinogen concentration during the initial management of Postpartum hemorrhage is the most informative biological marker for the severity of the hemorrhage. Various methods are used to record coagulation profile. One of them is estimation by sonoclot. Viscoelastic hemostatic assays devices (such as sonoclot) have practical advantages as point-of-care devices for monitoring major hemorrhage including a set of parameters that assesses a global coagulation profile like fibrinogen and platelet count. Identification of coagulopathy by viscoelastic point-of-care testing can be helpful in guiding management of Postpartum hemorrhage and preventing severe maternal outcomes.
In this study, researchers want to find out more about how the Etonogestrel (ENG) contraceptive implant device (also known as Nexplanon) changes people's periods. Study subjects will self select into an exposure group- starting combined hormonal contraceptive pills (COC) on the same day as Nexplanon placement or a "delayed initiation" of COC when/if bleeding concerns develop. Patients will be followed for 12 months.
In the present study, we test the ability of AMSS as a simple tool to identify women with HMB who have ID/ IDA. We will compare the AMSS score to patients' hemoglobin and serum ferritin in women with self-reported HMB and women with normal menstrual flow.
The objective of the randomized controlled study is to compare combination of sublingual misoprostol and routine uterotonics versus routine uterotonics alone on PPH in low risk women after vaginal delivery. The hypothesis is that combination of sublingual misoprostol and routine uterotonics is more effective than routine uterotonics alone in reduction of PPH in low risk women after vaginal delivery.
Researchers sought to see how oxytocin versus, sublingual misoprostol affected estimated and measured blood loss during vaginal delivery in women who had blood loss >300 ml .
Disc hemorrhages are a known risk factor for progression of glaucoma. A positive water drinking test is also associated with progression of primary open glaucoma. The purpose of this study is to determine if patients with normal tension glaucoma and disc hemorrhages have a positive water drinking test. Patients with normal tension glaucoma and a disc hemorrhage will be recruited to undergo a water drinking test prior to any change in their treatment.
