A prospective, multi-center, noninferiority randomized controlled trial designed to compare the efficacy of UI-EWD (Nexpowder™) hemostatic powder versus conventional endoscopic hemostatic therapy in patients presenting with acute overt gastrointestinal bleeding which is found at endoscopy to be due to a gastric or duodenal ulcer with active bleeding (spurting or oozing) or a non-bleeding visible vessel.
The investigators plan to study the effects of curcumin, the active ingredient in the spice turmeric, on the irregular bleeding experienced by women who use the contraceptive implant.
This is a Phase II placebo-controlled double-blind study of pomalidomide in patients with hereditary hemorrhagic telangiectasia (HHT) with moderate to severe epistaxis who have anemia and/or require parenteral iron infusions or blood transfusions. A total of 159 patients will be randomized 2:1 to treatment with oral pomalidomide or matching placebo for 24 weeks. Mean change from baseline to 24 weeks in the Epistaxis Severity Score (ESS) will be compared between treatment groups to determine pomalidomide efficacy.
The overall objective is to enroll patients with acquired hemophilia A (AHA) who are prescribed and treated with Obizur, to assess safety, and to describe factors related to safety, utilization and effectiveness in a real-world setting.
This document defines the Clinical Investigation Protocol for a study designed to determine whether blood loss after spontaneous vaginal delivery is altered by the addition of misoprostol administration to the standard use of intravenous oxytocin after delivery. The protocol is an open-label randomized prospective trial to be carried out at Queens Hospital Center. Blood loss will be measured indirectly by comparing the maternal hemoglobin and hematocrit levels on admission in labor to those obtained within 24 hours after delivery.

The aim of this study is to demonstrate that clazosentan, administered as a continuous intravenous infusion at 5 mg/h until Day 14 post aneurysmal subarachnoid hemorrhage (aSAH), reduces the incidence of cerebral vasospasm -related morbidity and all-cause mortality within 6 weeks post-aSAH treated by surgical clipping. The primary endpoint of the study is the occurrence of cerebral vasospasm-related morbidity, and mortality of all-causes within 6 weeks post-aSAH, defined by at least one of the following: 1. Death (all causes). 2. New cerebral infarct(s) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 3. Delayed ischemic neurological deficit (DIND) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 4. Neurological signs or symptoms (depending on state of consciousness), in the presence of confirmed cerebral vasospasm on angiography (DSA or CTA), leading to the administration of a valid rescue therapy. An independent Critical Events Committee (CEC) will adjudicate whether or not patients meet the primary endpoint and its individual morbidity components.
The purpose of this study is to determine whether a brief course of SSKI (saturated solution of potassium iodide) administered preoperatively provides any benefit in the surgical management of patients undergoing thyroidectomy as definitive management of their Graves Disease.
Researchers are looking for a better way to treat hemophilia A. Hemophilia A is a genetic disorder where the body does not create enough of a protein called clotting factor 8 (FVIII) present in the blood. People with hemophilia A may bleed for a long time from minor wounds, have painful bleeding into joints, or have internal bleeding. In severe hemophilia A (clotting factor 8 levels less than 1%) bleedings are more likely to happen. In this study researchers want to learn more about the treatment called BAY94-9027. BAY94-9027 is an injectable medicine used to replace missing clotting factor 8. In BAY94-9027 the clotting factor 8 has been pegylated (combined with a substance called polyethylene glycol (PEG)). This is to make the treatment last longer in the body so that less injections are required. BAY94-9027 is already available for the prevention and treatment of bleeding in adults and children who are 12 years and older. BAY 94-9027 is also called Jivi. BAY94-9027 is not yet available for children aged 7 to less than 12 years. One potential specific risk of pegylated drugs is that proteins in the blood called antibodies are built. These may attach to the pegylation part of the drug and this in turn may lead to allergic reactions and the drug not working as well as it should during first 4 infusions. In studies that have been done so far, this has been seen in some children younger than six years, but not in 29 children aged 6 to less than 12 years treated with BAY94-9027. Further safety information related to how the body reacts to BAY94-9027 is however still needed for this age group. The main purpose of this study is to learn how safe BAY94-9027 is (safety) and how it affects the body (tolerability) in previously treated children with severe hemophilia A who are between 7 to less than 12 years. To answer this question, the researchers will study information about two medical problems of special interest, if allergic reactions occur (also called hypersensitivity) and if the drug is not working as well as it should (also called loss of efficacy) during the first 4 infusions. Allergic reactions may range from mild local reactions to widespread effects such as shortness of breath, skin rashes and low blood pressure. Only allergic reactions related to the study treatment will be considered. The assessment if loss of efficacy occurred will be based on the occurrence of bleeding, the clotting factor 8 level in blood after injection called recovery, clotting factor 8 inhibitor tests and measurement of antibodies against the PEG. The study has two parts, A and B. Part A takes 6 months and part B takes 18 months. In part A the participants will receive two injections of BAY94-9027 per week. In part B, the number of injections may be decreased, with up to five days between the injections. The participants in this study will visit the study site around 14 times and will have 15 phone visits. In part A, visit 1 is for screening. Visits 2 to 5 take place twice a week for two weeks. Visit 6 two weeks after visit 5, visits 7 to 10 take place monthly with visit 11 six weeks after visit 10. In part B, site visits will occur on month 9, 12, 18 and 24 and phone calls every month between the site visits. The participants' and their caregivers will record in an electronic patient diary information about when the study treatment was given and bleeding episodes that have happened. During the study, the study doctors and their team will * take blood samples, * do physical examinations, * review the participants' electronic diary * ask questions about the participants' quality of life, * ask the participants questions about how they are feeling and what adverse events they are having An adverse event is a medical problem that happens during the study. Doctors keep track of all adverse events that happen in study, even if they do not think the adverse events might be related to the study treatments.

This study will define the limits of subretinal hemorrhage parameters that are consistent with a good visual outcome with aggressive anti-VEGF treatment in patients with neovascular age-related macular degeneration (NVAMD).
Pulmonary hemorrhage can be severe and life-threatening. In children, etiologies of pulmonary hemorrhage include respiratory infection, foreign bodies, bronchiectasis, pulmonary vascular disorders, parenchymal lung disease, and post-surgical complications. Initial management of pulmonary hemorrhage includes stabilization of the patient, securing the airway, initiative high positive end-expiratory pressure to attempt to tamponade the source of hemorrhage and repletion with blood products. Following stabilization of the patient, investigation and further management of hemorrhage includes bronchoscopy, surgery, or catheterization. Sources of bleeding such as endobronchial lesions are often identified and managed with bronchoscopy and the instillation of vasoactive medications or cold water to induce vasospasm and/or balloon tamponade. Vascular bleeding can be surgically ligated or embolized via catheterization. Unidentifiable bleeding occurs with distal vascular injury and is limited to attempted catheter guided embolization of bleeding vessels if found, supportive treatment, and correction of a coagulopathy if present. As etiologies of pulmonary hemorrhage vary, outcomes and prognosis in pediatric pulmonary hemorrhage are difficult to determine, however, mortality still remains a risk. Tranexamic acid (TXA) is a lysine analog that blocks the conversion of plasminogen to plasmin and the interaction with fibrin, preventing blood clot breakdown, thereby reducing bleeding. The United States (US) Food and Drug Administration approved the intravenous formulation of TXA for the treatment of bleeding patients with hemophilia in 1986 and the oral formulation for the use of severe menorrhagia in 2009. In 2011, The World Health Organization listed TXA as an essential medication based on its successful use in adult trauma-related hemorrhage. Studies show the successful off-label use of TXA in children for congenital heart surgery, orthopedic procedures, neurosurgical procedures, trauma, immune thrombocytopenic purpura, epistaxis, hemorrhage complicating a procedure, bilateral lung transplantation, chemotherapy injections, and bone marrow biopsies among other diagnoses and procedures. Very little data on the use of TXA for pediatric pulmonary hemorrhage exists. Only two case reports show TXA controlling hemoptysis in children with cystic fibrosis-related hemoptysis. A systematic review concluded that the use of TXA for hemoptysis was associated with a significant reduction in length of bleeding. A recent randomized control trial showed the TXA decreased the severity of the hemoptysis and may be used as a bridge to other interventions. The powerful anti-fibrinolytic properties and relatively low side-effect profile lend TXA to the off-label use in children to reduce bleeding in other diagnoses. There are not enough studies and data, however, to recommend the routine use of TXA in hemoptysis.
The etonogestrel (ENG) subdermal contraceptive implant (ENG implant) is a highly effective method of preventing pregnancy, but it has bleeding side effects that make it unappealing for many women. The only study to demonstrate a sustained reduction in bleeding lasting for two months was the selective estrogen receptor modulator (SERM) tamoxifen in users of the levonogestrel (LNG) contraceptive implant. Based on the investigators encouraging preliminary data of tamoxifen and ENG implant users, the investigators plan to perform additional studies on the impact of tamoxifen on the breakthrough bleeding experience by ENG implant users.
The purpose of the study is to evaluate the safety and effectiveness of the Cerene Cryotherapy Device in reducing menstrual bleeding in women with heavy menstrual bleeding (menorrhagia) due to benign causes for whom child bearing is complete.

The purpose of this study is to determine if the AEGEA Vapor System for endometrial ablation is safe and effective for reducing menstrual blood loss in women with excessive uterine bleeding (menorrhagia)
This double-blinded, placebo-controlled, randomized trial will compare the effects of the use of a combined oral contraceptive pill to a placebo pill for women who are experiencing irregular and/or heavy bleeding associated with the use of an etonogestrel (ETG) implant. The hypothesis of the study is: * Use of combined oral contraceptive will significantly improve bleeding patterns for users of ETG implant * Continuation rate of ETG implant users will be increased by use of combined oral contraceptive in women desiring ETG implant removal because of the undesirable bleeding * Adverse events will be uncommon and acceptable to women who use a combined oral contraceptive with the ETG implant
The purpose of the study is to determine the efficacy and safety of rFVIIa BI as part of a six-month on-demand treatment regimen in hemophilia A or B subjects with inhibitors.
The proposed study was set up to evaluate the tolerability and safety of 25% human albumin (HA) therapy in patients with subarachnoid hemorrhage (SAH). It is estimated that 37,500 people in the USA have SAH every year. SAH is associated with a 51% mortality rate and one third of survivors are left functionally dependent. Cerebral vasospasm (CV) has been identified as the most important reason for neurological deterioration. CV may be due to multiple molecular mechanisms. The use of a neuroprotective agent with various actions, likes HA, would be important for prevention of CV and improved clinical outcome in patients with SAH. The proposed open-label, dose-escalation study will have important public health implications by providing necessary information for a definitive phase III clinical trial regarding the efficacy of treatment with HA in patients with SAH. The study was to enroll a maximum of 80 patients with SAH who meet the eligibility criteria. Four dosages of HA (0.625, 1.25, 1.875, and 2.5 g/kg) administered daily for seven days will be evaluated. The lowest dosage was to be evaluated in the first group of 20 subjects. A specific safety threshold was defined based on data from previous studies. The Data and Safety Monitoring Board approved or disapproved advancing to the next higher HA dosage based on the evaluation of the rate of congestive heart failure (CHF). The study assessed three outcomes: safety and tolerability of the HA dosages and the functional outcome. The primary tolerability outcome was defined as the subject's ability to receive the full allocated dose of HA without incurring frank CHF that requires termination of treatment. Secondary safety outcomes were serious adverse events (including neurological and medical complications, and anaphylactic reactions). Neurological complications comprise incidence of CV, rebleeding, hydrocephalus, and seizures after treatment. The three-month functional outcome determined, by Glasgow Outcome Scale, Barthel Index, modified Rankin Scale, NIH Stroke Scale and Stroke Impact Scale was measured to obtain a preliminary estimate of the treatment effect of HA. The timeline of the study is three years.
