Filter by:Heavy periods is a significant problem in reproductive age .It affects about a third of women in the childbearing period Any of the following is considered to be heavy menstrual bleeding (Bleeding that lasts more than 7 days,Bleeding that soaks through one or more tampons or pads every hour for several hours in a row.Needing to wear more than one pad at a time to control menstrual flow.,Needing to change pads or tampons during the night or Menstrual flow with blood clots that are as big as a quarter or larger) . Heavy periods can be caused by organic cause as fibroids, adenomyosis, polyps or they can be dysfunctional.Dysfunctional uterine bleeding is irregular uterine bleeding that occurs in the absence of recognisable pelvic pathology, general medical disease, or pregnancy. It reflects a disruption in the normal cyclic pattern of ovulatory hormonal stimulation to the endometrial lining. Several treatment options include: hormonal treatment as norethisterone acetate,oral contraceptive pills, gonadotrophin releasing hormone analogue. ,tranexamic acid or non steroidal anti-inflammatory drugs. The investigators plan to do a comparative study between norethisterone acetate and tranexamic acid regarding their control of the heavy periods as well as their effect on the uterine and endometrial vasculature.
Variceal bleeding is a major complication of cirrhosis, associated with a hospital mortality rate of 10%-20%. Surviving patients are at high risk for recurrent hemorrhage. For these reasons, management should be directed at its prevention. Endoscopic variceal band ligation (EBL) in combination with non-selective β-blocker (NSBB) therapy is the recommended first line therapy. Transjugular intrahepatic portosystemic stent-shunt (TIPS) is the most effective method to prevent rebleeding, however, it is burdened with increased hepatic encephalopathy and deterioration of liver function in patients with advanced cirrhosis. So TIPS placement forms an alternative if first line therapy fails. Hepatic venous pressure gradient (HVPG) is currently the best available method to evaluate the presence and severity of portal hypertension. Patients who experience a reduction in HVPG of ≥20% or to <12mmHg in response to drug therapy are defined as 'responders'. The lowest rebleeding rates are observed in patients on secondary prophylaxis who are HVPG responders. A recent meta-analysis has demonstrated that combination therapy is only marginally more effective than drug therapy. This suggests that pharmacological therapy is the cornerstone of combination therapy. Adding EBL may not be the optimal approach to improve the outcome of HVPG nonresponders and HVPG non-responders are a special high-risk population that may benefit from a more aggressive approach, such as an early decision for TIPS. It recently was shown that TIPS placement within 72 hours after acute bleeding not only prevented recurrent bleeding but also improved survival. These raise the question of whether ligation together with NSBB should remain the first choice for elective secondary prophylaxis. Therefore, the purpose of the study is to compare whether HVPG-guided therapy is superior to standard combination therapy for the prevention of variceal bleeding in patients with decompensated cirrhosis.
This study is a non-inferiority, randomized controlled trial, based on the hypothesis that 4-factor PCC is not inferior to FFP in reducing perioperative blood loss in patients undergoing cardiac surgery under cardiopulmonary bypass. 796 subjects will be randomly divided into 2 groups (group PCC and group FFP), with 398 cases in each group. Patients will be given 8~15 IU/kg 4-factor PCC in group PCC and 6~10 ml/kg FFP in group FFP. All the patients will be followed up respectively at 24 hours, 48 hours, 72 hours and 7 days after the surgery. The primary outcome is the volume of blood loss within 24 hours after surgery. The secondary outcomes include (1) the total units of allogeneic red blood cells (RBCs) transfused within 7 days after surgery and (2) length of intensive care unit (ICU) stay. Adverse events and serious adverse events will be monitored as safety outcomes. Exploratory outcomes include re-exploration due to postoperative bleeding within 7 days after surgery and length of hospital stay.
Primary Objective: To identify the optimal interval to restart oral anticoagulation after traumatic intracranial hemorrhage that will minimize thrombotic events and major bleeding by performing a response adaptive randomized (RAR) PROBE clinical trial of restarting in anticoagulant-associated traumatic intracranial hemorrhage patients, comparing restart at 1 week to restart at 2 weeks or at 4 weeks, with a primary composite outcome of major thrombotic events and bleeding. Primary Outcome: 60-day composite of thromboembolic events, defined as DVT, pulmonary emboli, myocardial infarctions, ischemic strokes and systemic emboli, and bleeding events defined as non-CNS major bleeding events (modified BARC3 or above) and worsening index tICrH or new intracranial hemorrhage (ICrH). Secondary objectives of this trial include: 1. To use the Trauma Quality Improvement Program (TQIP) of the American College of Surgeons - Committee on Trauma (ACS-COT), a well-established and highly respected trauma center oversight mechanism, to translate findings of the trial into practice in a closed loop. 2. To establish a relationship between time of restarting and overall secondary events, i.e. a dose response, that favors early restarting (1 week is better than 2 weeks and 2 weeks is better than 4 weeks. 3. To explore patient centered utility weighting of thrombotic versus bleeding composite endpoint components by: A) 60-day Disability Rating Scale (DRS) 24,25 and modified Rankin Scale (mRS)26; B) Trial patient-reported standard gamble utilities including by race, gender and ethnicity. 4. To explore the composite without DVT in the thrombotic component
Variceal bleeding (VB) is a life-threatening complication of cirrhosis with a 6-week mortality of approximately 15%-20%. The 1-year rate of recurrent VB is approximately 60% in patients without prophylaxis treatment. Therefore, all patients who survive VB must receive active treatments to prevent rebleeding. Usually, these patients are submitted to rebleeding prophylaxis with endoscopic band ligation (EBL) combined with non-selective beta-blockers (NSBB). Transjugular intrahepatic portosystemic shunts (TIPS) are reserved for those who failed endoscopic plus medical treatment. A recent meta-analysis comparing combination therapy to monotherapy with EBL or drug therapy has demonstrated that combination therapy is only marginally more effective than NSBB alone. This suggests that NSBB is the cornerstone of combination therapy. The lowest rebleeding rates are observed in patients on secondary prophylaxis who are hepatic venous pressure gradient (HVPG) responders (defined as a reduction in HVPG below 12 mm Hg or > 20% from baseline). A recent study demonstrated that patients who have their first episode of variceal bleeding while on primary prophylaxis with NSBB have an increased risk of further bleeding and death, despite adding EBL. These patients possibly require alternative treatment approaches, such as TIPS. The aim of the present study was to compare the effect of TIPS vs. EBL + NSBB for the prevention of rebleeding in NSBB non-responder for primary prophylaxis.
The study is an investigator-sponsored, prospective, multicenter, randomized, open-label study designed to compare efficacy and safety between bivalirudin and heparin in patients with non-valvular atrial fibrillation undergoing percutaneous left atrial appendage occlusion.
Patients with subarachnoid haemorrhage frequently develop cardiac complications affecting their outcome
Spontaneous cerebral hemorrhage is one of the main causes of death and disability all over the world, accounting for 20%-30% of all cerebrovascular diseases. Minimally invasive surgery of cerebral hemorrhage, especially puncture aspiration, can improve early and long-term neurological recovery in patients with cerebral hemorrhage. Until now, no standardized practice for minimally invasive surgery of spontaneous cerebral hemorrhage has been established. Hematoma puncture and drainage based on CT scans without precise localization and personalized approach design, which may lead to poor efficacy and high risk of complications. The investigators' hospital has much experience in treating cerebral hemorrhage with stereotactic puncture and aspiration. So the investigators conduct a prospective multicenter randomized controlled clinical trial across the country to determine the therapeutic effects of puncture aspiration plus thrombolysis treatment for the perioperative and long-term recovery of patients with small hematoma in deep basal ganglia via computerized precision coordinates and personalized approach design.
Find out if there is a significant difference between clinical outcome among the patients with bleeding peptic ulcer treated with oral omeprazole compared to those treated with intravenous omeprazole.
Intracerebral hemorrhage (ICH) is one of the most devastating nontraumatic cerebral vascular diseases. Its exacerbation is often related to a mass effect because of hematoma formation and edema in the perihematoma, which plays a key role in disease deterioration. Perihematoma edema is an important contributor to brain injuries secondary to ICH and one of the risk factors that leads to disease deterioration and high mortality. Brain edema following ICH was believed to be induced by the breakdown of the blood-brain barrier and ischemia and hypoxia of the perihematoma. Normobaric oxygen (NBO) therapy is a treatment that delivers high-flow oxygen at normobaric pressure through a facemask to supplement the oxygen supply,which maintain the oxygen concentration of typically 40-100% ,can increase the arterial oxygen content, and alleviate tissue hypoxia. NBO therapy has been shown to provide neuroprotection against ischemic stroke in an experimental study and a clinical trial. To the best of our knowledge, the potential of NBO therapy for neuroprotection against human hemorrhagic stroke has not been investigated. There are two studies about NBO interventions in the rat model of intracerebral hemorrhage.The one showed NBO did not worsen hemorrhage severity or brain edema. There were no significant differences in hemorrhagic blood volumes or brain water content. NBO did not affect any of the neurological outcome tests in the primary or secondary studies. Another one showed NBO groups improved NSSs,decreased contents of brain water, HIF-1α and VEGF, and fewer apoptotic cells in the perihematoma at 72 h after ICH compared with the ICH control group. These results suggest that NBO therapy with oxygen delivered at 90% conferred best neuroprotection to ICH rats, potentially through amelioration of brain edema by suppressing HIF-1α and VEGF expression in the perihematoma. But there is no clinical study on the safety and efficacy of NBO in patients with intracerebral hemorrhage.NBO has the advantages of simple operation, non-invasiveness and early application, which makes it have great application prospects in the treatment of ICH.
