Active clinical trials for "Anemia, Iron-Deficiency"

Iron deficiency affects the opioid and dopamine systems in rodent models, with a higher pain threshold. The opioid system is involved in sucrose's ability to reduce pain and distress during neonatal procedures. Thus, prenatal iron deficiency might affect response to pain and sucrose analgesia. In order to compare response to pain and sucrose during heel stick in neonates with and without iron deficiency, healthy full-term Chinese infants were randomized to receive sucrose or water by syringe beforehand, in conjunction with heel stick for metabolic screening.

This study investigates the effects of intravenous (IV) iron sucrose therapy on blood levels of Fibroblast Growth Factor 23 (FGF23, a protein that regulates the amount of phosphate in the body) in iron deficiency anemia in healthy participants, participants with Congestive Heart Failure (CHF, where the heart does not pump adequate blood supply to the body), participants with Chronic Kidney Disease (CKD, where the kidney function is reduced), and participants with CKD and CHF.

This is a single center, prospective, observational study to demonstrate the clinical validity of the Intrinsic LifeSciences (ILS) Intrinsic Hepcidin IDx™ Test in the diagnosis and management of iron deficiency (ID) in adolescents and young adults. This test is considered non-significant risk.

The objective of the study is to assess the acceptability, feasibility, and barriers to Lucky Iron Fish™ (LIF) utilization among families with young children in a Latin American community with a high prevalence of iron deficiency and iron-deficiency anemia. .

Iron is involved in essential functions of the body. It allows the transport of oxygen in the blood, via hemoglobin, at the muscular level, via myoglobin, and it is also involved in cellular metabolism in general, in particular for the production of ATP at the mitochondrial level, within the cytochromes and iron-sulfur proteins of the respiratory chain. Recently, iron deficiency has been identified as an important prognostic factor in heart failure patients. Iron therapy improves symptoms and physical performances of heart failure patients, even in the absence of anemia. As a result, the correction of iron deficiency is now proposed as one of the therapies for heart failure. However, the pathophysiology of the association between cardiac dysfunction and iron deficiency is still poorly understood. The investigators previously developed a mouse model of iron deficiency without anemia, in which the investigators observed impaired physical performances, a decrease of left ventricular ejection fraction, and a decrease in mitochondrial complex I activity. These abnormalities were normalized after iron injection. These animal data suggest that iron deficiency is responsible for left ventricular dysfunction secondary to mitochondrial I complex abnormalities, and that iron therapy corrects them. Iron deficiency is very common in the preoperative period of cardiac surgery, affecting 40 to 50% of patients. During this surgery, it is possible to perform a myocardial biopsy without risk to the patient. The purpose of this study is to verify in patients requiring valvular heart surgery, if iron deficiency is responsible for a decrease in mitochondrial complex I activity and a decrease in cardiac function during the perioperative period, and to verify whether iron treatment improves these abnormalities.

Iron deficiency anemia affects over half of girls and young women with heavy periods and is the most common cause of anemia worldwide. Most girls with heavy periods who also have iron deficiency anemia are prescribed iron to take by mouth every day by their doctor. There are some studies showing that taking iron every other day may actually help the iron be absorbed into the bloodstream better. This study is trying to compare how taking iron every other day compares to taking iron daily for treatment of anemia. The goal of this clinical research study is to learn which of the two methods of care will be the best way for girls and young women with iron deficiency anemia to take iron supplementation.

In total 50 subjects with iron deficiency anemia treated with intravenous iron are planned for inclusion in this trial. After signing an informed consent a blood sample will be obtained from each participant before iron treatment. The investigators will measure the thrombin generation in plasma assessed by the calibrated automated thrombogram (CAT). patient will go face to face interview and will be asked to answer structured questionnaire which will include information on demographics, clinical data ( fever, allergies , etc.) and comorbidities Two weeks after completing intravenous iron administration additional blood samples will be taken: thrombin generation will be measured

We designed a double-blind, community-based, cluster-randomized control trial which will test to establish novel evidence on the efficacy of iron-fortified lentil in improving body Fe status of non-pregnant adolescents in rural Mymensingh district of Bangladesh. Lentils will be fortified with iron in the lab setting at the Crop Development Center (CDC) of the University of Saskatchewan in Canada. There will be three lentils based dietary intervention arm in this efficacy trial. Arm 1 will be intervened with iron-fortified lentils, Arm 2 will be non-iron fortified lentils, and Arm 3 arm will be the usual intake of lentil (no additional lentil). Arm 2 will be served as a comparison group and arm 3 will be served as control group. A total of 420 adolescent girls (including 20% drop-outs) - aged 10 - 17y; non-smoking, not pregnant, not breastfeeding, and generally healthy will be included in each arm - a total of 1260 adolescent girls in all three arms. Participating adolescents will be served thick preparation of cooked lentils (37.5gm raw lentil) 5 days a week for 85 feeding days (around 4+months). Socio-demographic characteristics, household food security status, and adolescent food habits will be collected at baseline and endline data point. Furthermore, venous blood will be collected to measure adolescents' Fe status at baseline, midline, and endline for 85 feeding days (5 days a week)- approx. 4+ months. In addition, Ravens Progressive Matrices will be used for non-verbal measurement of the cognitive ability of advanced observation and thinking skills specific to capacity for analyzing and solving problems, abstract reasoning, and the ability to learn of the adolescents. Both descriptive and inferential statistics will be used for this study. Serum ferritin level and cognitive performance is the primary outcome. The trial expects that the supplemental Fe from the iron-fortified lentils will improve body Fe status and cognitive performance after controlling for baseline Fe status and dietary Fe intake in this group of adolescent girls. The secondary outcome is the participants' anthropometries. Considering the amount of plant protein from lentils that need to be consumed to for the study, it is expected to have significant improvement in growth of the participants which will lead to increased productivity.

ID/IDA affects many young children in Africa. Vaccines provide tremendous benefits in LMIC; however, they currently fail to reach their full potential. We need to better understand the causes of vaccine failure, in order to develop new strategies to improve vaccine immunogenicity. This study will contribute to children's health by: (1) providing updated guidelines to better define the prevalence of ID/IDA in early infancy, and its safe and effective control using iron; and (2) providing a new approach to improve response to pediatric vaccines in LMIC, by ensuring adequate iron status at time of vaccination.

Scoliosis is a condition in which there is curvature of the spine occurring in the lateral plane. It occurs in structural forms, characterized by a fixed curve, and "functional" forms, characterized by a flexible or correctable curve. By anatomic necessity, this lateral deviation is associated with vertebral rotation, such that when this deformity occurs in the thoracic spine, a chest wall deformity, or "rib hump," develops. Often there is a primary structural curve with an adjacent secondary compensatory curve. Most cases of structural scoliosis are idiopathic and have their onset in early adolescence. Females are affected more often than males, and their curvature is more likely to worsen. Lumbar fusion surgery is usually associated with massive blood loss. In clinical practice the surgeon might measure the visible peri-operative bleeding including intra- and post-operative drainage, but ignore blood component penetration into the tissues, residual blood in vertebral canal and loss due to haemolysis, which are also known as hidden blood loss. In patients with adolescent idiopathic scoliosis (AIS), surgical treatment involves a posterior approach with multi-segmental pedicle screw fixation. Although this procedure is generally considered safe with few surgical complications, there are considerable variations in fusion length, surgical time, and the extent of soft-tissue exposure. Consequently, perioperative blood loss can be substantial, and the use of intraoperative and postoperative RBC transfusions are frequently required. Patient blood management (PBM) is an evidence-based, multidisciplinary approach developed over the last 10 years focusing on improving patient outcomes as well as reducing the use of RBC transfusions. PBM includes several preventive measures to manage bleeding risks, reduce iatrogenic blood loss, and modify decision thresholds for the appropriate administration of blood therapy. All patients for elective surgery in whom blood loss is expected to be > 500 ml should have their hemoglobin checked pre-operatively and be investigated if they are found to be anemic. In the general population, anemia is defined as a hemoglobin less than 130 g. in men and less than 120g. in women by the WHO. It was proposed that the cut-off value/trigger be changed to hemoglobin more than 130 g for both men and women. Women with hemoglobin levels between 120 and 129 g. are not considered to be anemic according to the WHO definition, leaving them at a potential disadvantage when undergoing major surgery
