Active clinical trials for "Hemorrhage"

Kidney biopsy represents the criterion standard to obtain information on diagnosis and prognosis of renal dysfunctions . Many patients with kidney disease have a predisposition to bleed, especially when they undergo an invasive procedure such as renal biopsy. The predominant factor is abnormal platelet function. Therefore, the aim of this study is to evaluate whether the platelet function analyzer (PFA-100), a very reliable test to investigate primary hemostasis, can be useful in predicting the risk of bleeding complications in patients undergoing renal biopsy.

Aim of this study is to describe clinical and procedural characteristics of real-world population initiated on triple antithrombotic therapy (double antiplatelet therapy+anticoagulant) or double antithrombotic therapy (single antiplatelet therapy+anticoagulant) after percutaneous coronary intervention (PCI). Investigator's driven trial, retrospective (2015-2019), multicenter Italian registry. Baseline clinical characteristics as well as procedural details will be collected retrospectively. Follow-up data (minimum 6 months and maximum 5 years follow-up) will focus on combined rates of stent thrombosis and myocardial infarction (primary endpoint).

Stroke is the first most common cause of death in China and one of the major causes of functional disability in the adult population.The burden of stoke is significantly increased in China in recent years. In order to investigate the prognosis of stroke, with diagnostic and treatment information of traditional Chinese medicine (TCM), and assess the effectiveness and safety of TCM for stroke in southern China, the investigators will conduct this multicenter prospective registry study in southern China. This study will recruit 10,000 consecutive eligible patients with acute stroke from more than 50 hospitals. 24 months follow-up will be carried out on-site in hospitals and by telephone to track endpoint (including all-cause mortality, composite cerebrovascular and cardiovascular events at one and two year follow up, and neurological and functional assessments).

From patient charts we will review patients who had undergone cesarean section within the last 6 months and identify those who received a The Hayman uterine compression suture for uterine atony. We will also select patients who delivered a baby without recieving a Hayman suture to create a control group. Patietns will be grouped as Hayman Group if they recevied a Hayman suture during C/S and control group if thay had not recevied a Hayman suture. We will then check patient charts for post-cesarean outpatient clinic visit and select those who received ovarian reserve evaluation via hormones and antral follicle count during the visits. Finally, we are planning to investigate any correlation between Hayman suture and ovarian dysfunction.

Vitamin D has been promoted to vascular regeneration in non-cerebral arteries because of its anti-inflammatory properties. Cerebral vasospasm (CVS) as the most feared complication after subarachnoid hemorrhage (SAH), correlated with higher mortality and poor outcome, is the result of a multifactorial mechanism with inflammation as one of the main role players. The investigators therefore hypothesized that vitamin D attenuates cerebral vasospasm and increases the chance for favorable outcome after SAH.

To find superiority relationship between oral and intravenous administration of tranexamic acid on peroperative and postoperative blood loss, haemarthrosis prevalence and improvement functional prognosis in anterior cruciate ligament arthroscopy.

To compare the prognosis of patients with hypertensive intracerebral hemorrhage treated by two different surgical methods, and to clarify the therapeutic effect of minimally invasive surgery, so as to find a better surgical method that can reduce surgical trauma and mortality and improve the prognosis of patients

Aim of the study The investigators aim to establish: Whether noradrenaline (NA) infusion has a significant effect on coagulation and fibrinolysis in patients with severe traumatic brain injury (TBI). Whether disruption of haemostasis can be recorded with a computerized tomography (CT) scan. Whether there is a significant difference between the values of haemostasis parameters in the internal jugular vein and the radialis artery. The hypotheses In the early stage of treatment (1-3 hours), an increased formation of thrombin occurs in patients with severe isolated TBI that are treated with NA; consequently, platelet use increases in comparison with patients who don't need NA, as do coagulation factors and hyperfibrinolysis. The concentration of NA correlates with thrombin formation and the correlation is stronger in higher doses of NA. Thrombin formation will decrease more slowly in the group that will receive NA therapy in comparison to the group that will not receive NA therapy.

Autoimmune diseases are diseases in which inappropriate immune responses that have the capability of harming host cells play an important role. Evidence suggests that the presence of certain autoimmune diseases such as rheumatoid arthritis or systematic lupus erythematosus increase the risk of cardiovascular disease (CVD). However, this evidence is inconsistent for autoimmune disorders and no systematic approach has been previously used to study the relationship between a range of common autoimmune disorders and specific forms of cardiovascular diseases such as myocardial infarction, intracerebral and subarachnoid haemorrhage, or venous thrombosis. The investigators will use linked electronic health records to investigate whether commonly diagnosed autoimmune disorders are associated with increased risk of CVD development and whether effects differ in men and women and change with age.
