Filter by:The investigators plan a study to randomize 540 children in Nepal to early (≤30 seconds) or late (≥180 seconds) clamping of the umbilical cord at birth. The children will be followed with blood tests (hemoglobin and ferritin) at 8 and 12 months of age, and their development is evaluated by questionnaire (Ages & Stages Questionnaire ) at 12 months of age, and by testing (Bayley -III) at 18-24 months of age. By implementing the project in a country with a high proportion of anemia at one year of age (about 75%), we can reduce the number of children in the study and still achieve significant results. Iron deficiency is a global health problem and causes anemia and impaired neurodevelopment in children. Anemia is estimated by WHO to occur among 25% of all children before school age, and the corresponding figure in Europe is 3-9 %. By waiting 3 minutes to clamp the cord after birth, a large part of the child's blood volume remaining in the placenta is transfused over to the child's body. Research shows that the neonate's blood volume can increase by about 40% and this blood contains 3 to 4 months' supply of iron. In Sweden, we have shown that late clamping of the umbilical cord could reduce iron deficiency in children at four months of age by 90%. Globally, most countries practice early cord clamping and the child is deprived of the placental blood transfusion. The hypothesis of the study is that by delaying the clamping of the umbilical cord, anemia at 8 and 12 months will be reduced an this in turn will be beneficial for the childrens development. The project will be implemented at Paropakar Maternity and Women 's Hospital, Kathmandu. It hosts approximately 23,000 births annually.
According to a national study in 2002, the prevalence of ID, IDA, and ID+IDA among pregnant women in China was 42.6%, 9.1%, and 61.7% respectively. A similar study in Hebei province at the same time showed that the prevalence of IDA among pregnant and lactating mothers was 46.39% and 47.21% respectively. There was a significant difference between urban and rural areas. Women living in rural areas had higher chances of having IDA (p<0.01). WHO and UNICEF recommend taking iron, folic acid and multiple micronutrients during pregnancy. However, we don't know much about their influence on maternal and infant health and their clinical effectiveness. Health Department of China recommends taking 400ug folic acid before pregnancy and during early pregnancy. But for various reasons, not all expecting mothers take this advice. Besides, we don't have a national level technical standard of how to take nutrition supplements during pregnancy. Therefore, it's crucial for us to study if iron/folic acid or folic acid only can prevent perinatal complications, as well as their influences on infant and toddler health. The purpose of this study is to test whether taking iron/folic acid and folic acid only from early pregnancy until delivery will lower the chances of pregnancy complications, and to see how supplements affect gestation results. As well, it will evaluate a) whether taking iron supplement during pregnancy can prevent IDA during pregnancy; b) whether taking iron supplement can increase mother and fetus iron storage; and c) how mother's iron level affects newborn's iron level. We hope to understand nutrition conditions during pregnancy and investigate the relations between pregnancy diet and complications during pregnancy, weight gain during pregnancy, and newborn birth weight. We will evaluate the influence of taking iron and folic acid during pregnancy on the health of infants and toddlers.
The purpose of this study is to determine whether cholecalciferol supplementation decrease the blood concentrations of hepcidin-25 in hemodialysis patients.
The investigators clinical trials will be for a medical device that is non-invasive in nature. The investigators will be studying whether their non-invasive medical device gets data that is as good as, or better than, an FDA previously approved, blood analysis device. There is no study hypothesis for this study.
Severe acquired aplastic anaemia (SAA) is a bone marrow failure disease characterized by pancytopenia and a hypocellular bone marrow. The corn pathophysiological mechanism is the destruction of hematopoietic stem/progenitor cells mediated by auto-reactive effector T cells. Immunosuppressive therapy with horse antithymocyte globulin (ATG) plus cyclosporine (CSA) is currently the standard of treatment in patients with aplastic anaemia who are not eligible for bone marrow transplantation and with response rates from 40% to 70%. Previous studies showed that horse ATG (hATG) is apparently more effective than rabbit ATG (rATG) as the latter has higher treatment related mortality (TRM). Unfortunately hATG is unavailable in China, so we conduct a optimized standard treatment (9 days protocol) of rATG plus CSA and Levamisole (LMS) Sequential maintaining (termed Optimized Standard Protocol, OSP) for severe aplastic anemia. This prospective study is designed to evaluate the efficacy and safety of Optimized Standard Protocol as first line therapy in newly diagnosed severe aplastic anemia patients.
Anti-inflammatory tablets (non-steroidal anti-inflammatory drugs) continue to be used commonly worldwide to relieve pain caused by arthritis. Likewise, aspirin is used by many patients in order to prevent blood clots. Despite their desired benefits, these medicines can cause internal bleeding from the digestive system. The source of this bleeding can be obvious (overt), or obscure and thought to come from the small intestine. Obscure bleeding can show as anemia due to lack of iron in the blood. Small intestine ulcers are now easily diagnosed using an endoscope the size of a big pill (video capsule endoscopy). Small bowel ulcers are not related to stomach acid and therefore do not heal using remedies usually taken to stop acid formation. A different drug, misoprostol, consists of a chemical (prostaglandin) that is usually lacking in patients using aspirin or anti-inflammatory drugs. Misoprostol is licenced to heal stomach and duodenal ulcers in patients using these drugs. Our hypothesis is that misoprostol might be effective in healing small bowel ulcers as suggested by pilot studies; however, such works only included small numbers of patients, did not include control groups and both patients and investigators knew the nature of the tablets used. To test this hypothesis, we propose to compare misoprostol to a dummy tablet. The numbers of subjects to be studied have been calculated using established statistical methods
Patients with end-stage kidney disease on maintenance hemodialysis frequently require iron supplementation to compensate for ongoing iron losses, and to maintain hemoglobin levels with or without additional use of erythropoiesis-stimulating agents (ESA). The investigators aim to compare two different intravenous iron preparations, ferric carboxymaltose and iron sucrose in 140 hemodialysis patients. The investigators primary objective is to assess whether both agents are equally effective to maintain a target haemoglobin within 10-12 mg/dl. The investigators will also measure ferritin, transferrin, transferrin saturation, and how much ESA therapy is administered. Patients will be randomly assigned to either treatment group and followed in parallel over an active study period of 40 weeks.
Study Hypotheses: 1. Anaemia, which is frequent before conception as well as during early pregnancy, affects metabolism and foetal growth trajectories, influencing the risk of NCDs in the offspring. 2. Anaemia from conception till end of 2nd trimester is most detrimental for foetal and newborns' health, compared to 3rd trimester anaemia. 3. Anaemia from conception till end of 2nd trimester affects foetal and newborns health through poor placental development reflected in increased villous branching and changed umbilical and uterine blood flow. 4. Anaemia in early pregnancy disrupts the vascular endothelial growth factor A (VEGF-A)/placental growth factor (PlGF) balance and the insulin-like growth factor (IGF) axis resulting in poor placental development, and poor health of newborns. This may be reflected in specific methylation patterns. 5. Anaemia's impact on the risk for NCDs in the offspring may be mediated via epigenetic mechanisms, including changes in DNA methylation patterns.
Anemia which is a decreased blood count or lower than normal hemoglobin (hgb), is a major health problem for patients having heart surgery. Hemoglobin is the part of our blood that carries oxygen from the lungs to the rest of the body. Anemia that is present before surgery, called preoperative anemia, is a risk factor for an increased chance of morbidity (illness) and/or mortality (death) after heart surgery. It is also an important indicator of blood transfusion necessity. Recent clinical research investigations done to study preoperative anemia suggest a blood transfusion can damage the immune system (the system that protects us from disease) which can lead to infection, organ dysfunction (especially of the heart, kidney, brain), prolonged hospital stays, as well as increased supplies, resources and cost in surgical patients. Comprehensive anemia management can reduce or eliminate the need for blood transfusions and provide better outcomes after surgery. Therefore, controlling anemia before surgery is extremely important, and could be a lifesaving measure. This pilot, feasibility study is being done for several reasons. First of all, it will test the the safety and effectiveness of using a short-course of two medications, erythropoietin (EPO) and Feraheme (iron given intravenously [IV]), to increase hemoglobin levels in order to improve preoperative anemia, reduce transfusions and lower postoperative complications in anemic patients undergoing heart surgery. Secondly, findings will be used to design a large randomized controlled trial (RCT). The RCT will establish a protocol to actively manage anemia before surgery, thus reducing transfusions during surgery and improving recovery afterwards. It will also help identify valuable information regarding what needs to be done for timely completion of the planned RCT. EPO is a medication approved by the Food and Drug Administration (FDA) used to treat anemia in patients with certain conditions in order to reduce blood transfusions. And although approved for use during surgery, it has not been FDA approved for use in cardiac (heart) or vascular (blood vessels, including veins and arteries) surgery. Common side effects include nausea, vomiting, itching, headache, injection site pain, chills, deep vein thrombosis (blood clot), cough, and changes in blood pressure (BP). Feraheme is an iron replacement product approved for the treatment of low iron anemia in adult patients. It may cause serious allergic reactions, including anaphylaxis (severe, whole body allergic reaction), as well as low BP and excessive iron storage. Patients meeting all eligibility requirements that consent to participate will be randomized into the study. Randomization is being placed by chance (like a flip of a coin) into one of two study groups, the treatment group or the control group. There is an equal chance of being placed into either group, which will be done by a computer. 1. The Treatment Group will receive a 300 unit (U) per kilogram (kg) injection of EPO and a 510 milligram (mg) IV infusion of Feraheme 7-28 days before the day of surgery. And again 1-7 days before the day of surgery, a second dose of both of these medications will be given. The third dose, of EPO only, will be administered 2 days after surgery. Before initiating a dose or giving a subsequent dose, laboratory parameters will be measured to assess the hemoglobin level and response to the medication. If blood values increase too rapidly or are too high, the meds will not be started or, if already dosed, they will not be given again. 2. The Control Group will receive no preoperative intervention for anemia unless lab results show iron deficiency anemia. The control group will be screened for the presence of iron deficiency anemia by evaluating blood laboratory values drawn during the baseline or preoperative visit. If lab results indicate iron deficiency anemia, over-the-counter oral iron will be recommended, to take until the day of surgery. In doing so, patients may benefit by potentially reducing the need for blood transfusions. Data will be collected from all participants from the preoperative visits throughout the admission, including lab results, medications, vital signs, information about the procedure, transfusions, and any problems or adverse events.
