The aim of this study is to investigate the effects of intravenous (IV) iron therapy compared to alternate-day oral iron treatment and no supplementation in older patients with hip fractures. This study will examine the impact of iron treatment on fatigue, functional decline, fear of falling, cognitive impairment, and quality of life, as well as its effects on iron stores and hemoglobin levels, with the overall goal of improving postoperative rehabilitation. The trial will be conducted on five different hospitals in the Central Region of Denmark (Region Midtjylland).
NCT05087303
The purpose of this study is to learn more about how the use of two different types of telemedicine (distance medical care) can address barriers to receiving comprehensive sickle cell care, and whether care can be improved. Aim 1: Adapt two telemedicine models (i.e., hub-and-spoke; direct-to-consumer) for use with children with SCD using caregiver input from our preliminary K12 work. Aim 2: Demonstrate the feasibility of the telemedicine models developed in Aim 1 as the models undergo successive stakeholder refinement during use in actual clinical care. Aim 3: Evaluate the effectiveness of the refined models from Aim 2 in a pre/post study by assessing (a) process of care measures, (b) provider satisfaction, (c) caregiver/patient-centered outcomes, and (d) clinical outcomes and healthcare utilization.

NCT06622551
This clinical trial aims to learn if there is a relationship between OWT/OB and IDA in nonpregnant women of reproductive age and its impact on iron supplementation. The main questions it aims to answer are: * Is there any independent association between overweight/obesity and iron deficiency anemia in nonpregnant women after controlling for potential confounding factors? * Does the effect of iron supplementation on iron status vary between overweight/obese and normal-weight nonpregnant women (as measured by multiple iron biomarkers)? Researchers will compare several biomarkers between the case and control groups after the intervention is given for 90 days. Participants will: * Visit the research center before the intervention given and after 90 days * Take daily iron-folic acid supplements for 90 days * Keep a diary of their supplement's intake
NCT05675436
Background: Sickle cell disease (SCD) is an inherited blood disorder. The disease affects the ability of red blood cells to carry oxygen; this in turn can injure organs including the heart, lungs, and kidneys. SCD can lead to serious illness and death. Treatments such as bone marrow transplants and gene therapies can cure SCD, but they are not widely available. Current drug treatments for SCD are not always effective. This natural history study will examine how a study drug (mitapivat) affects red blood cells in people with SCD. Objective: To learn how mitapivat affects red blood cells in people with SCD. Eligibility: People with SCD who are enrolled in the parent study, NIH protocol IRB001565-H. Design: Procedures for this study will be done during visits already scheduled for the parent study. Participants will have additional blood drawn during study visits. The additional amount will be about 3.5 teaspoons. Participants will undergo a test called near infrared spectroscopy (NIRS) up to 9 times. Probes will be placed on their skin. A blood pressure cuff will be placed on their arm. The cuff will be filled with air for up to 5 minutes and then released. Participants may be asked to breathe at a certain rate or to hold their breath during these measurements. NIRS measures oxygen levels, blood flow, and the makeup of skin and muscle. Researchers will draw additional information for this study from participants medical records.
NCT07522996
This study aimed to compare the efficacy and safety of enarodustat combined with cyclosporine versus cyclosporine alone in the treatment of TD-NSAA.
NCT07623161
The main aim of this study is to find out how well elritercept works to improve anemia in participants with myelofibrosis (MF) who are taking ruxolitinib when compared to placebo. Other aims are to learn how elritercept improves anemia compared to placebo; to learn if elritercept reduces tiredness, improves symptoms related to MF, and helps participants do physical activities more easily. The study also aims to find out how elritercept affects the bone marrow, the spleen, and whether participants develop antibodies to the study drug. The study will also check how safe elritercept is compared to placebo, and if elritercept stays safe over a long period of time. Participants will receive study treatment for at least 9 months (36 weeks). After this period, participants who received placebo will have the option to switch to elritercept.
NCT06125860
The goal of this randomized effectiveness study is to evaluate the different targeting strategies for the delivery of balanced energy and protein (BEP) supplements among pregnant women in Addis Ababa, Ethiopia. The main goals of the study are to: 1) determine the effectiveness of two individual-based antenatal BEP targeting strategies for preventing adverse pregnancy outcomes; 2) compare the cost-effectiveness of the universal BEP provision with two individual-based targeting strategies for preventing adverse pregnancy outcomes; and 3) generate implementation evidence regarding the feasibility and acceptability of different antenatal BEP targeting strategies. Pregnant women will be enrolled during pregnancy, assigned to different strategies of BEP supplementation, and followed from pregnancy through six weeks postpartum to evaluate the impacts of different BEP targeting strategies on pregnancy, maternal, and child outcomes.
NCT03520647
Background: Severe aplastic anemia (SAA), and myelodysplastic syndrome (MDS), and paroxysmal nocturnal hemoglobinuria (PNH) cause serious blood problems. Stem cell transplants using bone marrow or blood plus chemotherapy can help. Researchers want to see if using peripheral blood stem cells (PBSCs) rather than bone marrow cells works too. PBSCs are easier to collect and have more cells that help transplants. Objectives: To see how safely and effectively SAA, MDS and PNH are treated using peripheral blood hematopoietic stem cells from a family member plus chemotherapy. Eligibility: Recipients ages 4-60 with SAA, MDS or PNH and their relative donors ages 4-75 Design: Recipients will have: * Blood, urine, heart, and lung tests * Scans * Bone marrow sample Recipients will need a caregiver for several months. They may make fertility plans and a power of attorney. Donors will have blood and tissue tests, then injections to boost stem cells for 5-7 days. Donors will have blood collected from a tube in an arm or leg vein. A machine will separate stem cells and maybe white blood cells. The rest of the blood will be returned into the other arm or leg. In the hospital for about 1 month, recipients will have: * Central line inserted in the neck or chest * Medicines for side effects * Chemotherapy over 8 days and radiation 1 time * Stem cell transplant over 4 hours Up to 6 months after transplant, recipients will stay near NIH for weekly physical exams and blood tests. At day 180, recipients will go home. They will have tests at their doctor s office and NIH several times over 5 years.
NCT07578675
Anemia is a global public health concern and is closely linked to dysfunction of brain cognitive neural networks, a key mechanism underlying cognitive impairment. Such deficits-including declines in memory, learning, processing speed, and executive function-reduce daily living abilities and increase risks of falls and depression. Functional near-infrared spectroscopy (fNIRS) enables real-time monitoring of oxygenated and deoxygenated hemoglobin fluctuations, reflecting brain network function. This study aims to identify affected neural network regions in anemic patients and visualize connectivity changes using heatmaps and arc-based mapping. The findings will support early detection of cognitive impairment and guide precise clinical interventions, ultimately informing individualized treatment strategies to enhance therapeutic outcomes and quality of life.

This phase II trial studies the effect of acalabrutinib in treating autoimmune hemolytic anemia that has come back (relapsed) or has not responded to previous treatment (refractory) in patients with chronic lymphocytic leukemia. Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
NCT05012111
Background: Bone marrow failure diseases are rare. Much is known about the diseases at the time of diagnosis, but long-term data about the effects of the diseases and treatments are lacking. Researchers want to better understand long-term outcomes in people with these diseases. Objective: To follow people diagnosed with acquired or inherited bone marrow failure disease and study the long-term effects of the disease and its treatments on organ function. Eligibility: People aged 2 years and older who have been diagnosed with acquired or inherited bone marrow failure or Telomere Biology Disorder. First degree family members may also be able to take part in the study. Design: Participants will be screened with a medical history, physical exam, and blood tests. They may have a bone marrow biopsy and aspiration. For this, a large needle will be inserted in the hip through a small cut. Marrow will be drawn from the bone. A small piece of bone may be removed. Participants may also be screened with some of the following: Cheek swab or hair follicle sample Skin biopsy Urine or saliva sample Evaluation by disease specialists (e.g., lung, liver, heart) Imaging scan of the chest Liver ultrasounds Six-Minute Walk Test Lung function test Participants will be put into groups based on their disease. They will have visits every 1 to 3 years. At visits, they may repeat some screening tests. They may fill out yearly surveys about their medicines, transfusions, pregnancy, bleeding, and so on. They may have other specialized procedures, such as imaging scans and ultrasounds. Participation will last for up to 20 years. ...
NCT07565701
The goal of this study is to assess if patients can be retained on long-term vadadustat therapy (and thus potentially benefit from the favorable safety profile) by incorporating a phased transition from Epogen to three times per week vadadustat (TIW-V), reducing the likelihood of GI intolerance through use of a lower vadadustat starting dose, and also reducing or eliminating the initial reduction in hemoglobin through the maintenance of low dose Epogen until target hemoglobin stability is achieved on a tolerable dose of TIW-V.

This is a phase I/II protocol investigating whether Nelfinavir can improve anemia and lower serum fibrosis biomarkers in Myelofibrosis patients.
NCT04610866
Background: Sickle cell disease (SCD) is a disorder that causes episodes of acute pain and progressive organ damage. Ways to manage SCD have evolved slowly. Treatments do not always work. Researchers want to see if a drug called mitapivat can help people with SCD. Objective: To test the long-term tolerability and safety of mitapivat (or AG-348) in people with SCD. Eligibility: Adults age 18-70 with SCD who took part in and benefited from NIH study #19H0097. Design: Participants will be screened with a medical history and physical exam. They will give a blood sample. They will have an electrocardiogram to test heart function. Participants will repeat some of the screening tests during the study. Participants will complete 6-minute walk tests to measure mobility and function. They will have transthoracic echocardiograms to measure heart and lung function. They will have dual-energy X-ray absorptiometry scans to measure bone health. They will complete online questionnaires that measure their overall health and well-being. Participants will take the study drug in the form of a tablet twice a day. Participants will keep a study diary. They will record any symptoms they may have. Participation will last for about 54 weeks. After 48 weeks, participants can either keep taking the study drug for 48 more weeks or be tapered off of the study drug to complete the study. Those who are on the study for 1 year will have 10 study visits. Those who are on the study for 2 years will have 14 study visits.
NCT05144256
ACTIVATE-KidsT (AG348-C-022) is a multicenter study designed to evaluate the efficacy and safety of treatment with mitapivat compared with placebo in pediatric participants with pyruvate kinase deficiency (PK deficiency) who are regularly receiving blood transfusions. Participants will be randomized 2:1 to receive either mitapivat or matching placebo. Randomization will be stratified by age (1 to \< 6 years, 6 to \< 12 years, 12 to \< 18 years) and splenectomy status. Participants will be dosed by age and weight during a double-blind period consisting of an 8-week dose titration period followed by a 24-week fixed-dose period. Participants who complete the double-blind period will be eligible to receive mitapivat in the open-label extension (OLE) period.

NOTE: This is a research study and is not meant to be a substitute for clinical genetic testing. Families may never receive results from the study or may receive results many years from the time they enroll. If you are interested in clinical testing please consider seeing a local genetic counselor or other genetics professional. If you have already had clinical genetic testing and meet eligibility criteria for this study as shown in the Eligibility Section, you may enroll regardless of the results of your clinical genetic testing. While it is well recognized that hereditary factors contribute to the development of a subset of human cancers, the cause for many cancers remains unknown. The application of next generation sequencing (NGS) technologies has expanded knowledge in the field of hereditary cancer predisposition. Currently, more than 100 cancer predisposing genes have been identified, and it is now estimated that approximately 10% of all cancer patients have an underlying genetic predisposition. The purpose of this protocol is to identify novel cancer predisposing genes and/or genetic variants. For this study, the investigators will establish a Data Registry linked to a Repository of biological samples. Health information, blood samples and occasionally leftover tumor samples will be collected from individuals with familial cancer. The investigators will use NGS approaches to find changes in genes that may be important in the development of familial cancer. The information gained from this study may provide new and better ways to diagnose and care for people with hereditary cancer. PRIMARY OBJECTIVE: * Establish a registry of families with clustering of cancer in which clinical data are linked to a repository of cryopreserved blood cells, germline DNA, and tumor tissues from the proband and other family members. SECONDARY OBJECTIVE: * Identify novel cancer predisposing genes and/or genetic variants in families with clustering of cancer for which the underlying genetic basis is unknown.
