Filter by:Iron is very important for our body and performs vital tasks. Iron deficiency is a worldwide health problem. The prevalence of anemia in women of reproductive age in Southeast Asia is estimated to be 46.6% in 2019, with iron deficiency being one of the main reasons for anemia. There are different approaches to treat iron deficiency. One of them is the use of iron supplements. Recommended iron supplement treatments today often differ in dose, regimen and length. Experts recommend a dose of 80-200 mg of iron taken either daily or on several days per week, depending on the severity of the iron deficiency (with or without anemia). From certain guidelines lower amounts of iron are also recommended, as this could lead to fewer side effects.Previous studies have shown that both daily and multiple days per week administration can be effective in treating iron deficiency. Recently, several successive iron supplementation studies in Zurich showed that 24 h after ingestion of an oral dose of >60mg iron, the absorption of iron in the body is impaired. In addition it was measured that iron supplements taken only every other day instead of every day are absorbed about 30-50% better and have fewer side effects. Little is known about the long-term effect of this alternating regimen on iron status and side effects.With this 6-months study in the Philippines, the investigators want to compare two different supplementation regimens with oral iron to see if there is any difference in the iron status, intestinal inflammation levels, and side effects, and therefore if it would be better to take the iron supplements every 2 days instead of daily.
Participants are required to undergo a screening and qualification before beginning the study. Once qualified, baseline testing is completed in the laboratory. This testing includes: body composition measurements, a blood draw, questionnaires, a VO2 max test, and a time to exhaustion trial. This testing is repeated during week 4 and week 12. At week 8, subjects complete a blood draw and questionnaires only. During the 12 week period, participants will follow an endurance exercise program in which they will train 4 days per week. This is a double-blind study in which participants are randomized into either the placebo or supplement group. They are instructed to ingest the supplement once a day at breakfast. Diet logs are also monitored throughout the duration of the study with the restriction of no red meat.
The purpose of this study is to better understand how body levels of iron affect the ability to exercise in patients with heart failure (HF). Heart failure is a condition in which abnormal pumping action of the heart reduces the flow of blood to the body. Patients with heart failure may feel shortness of breath or leg fatigue when they exercise. Iron is an essential nutrient in the diet. In heart failure patients, low body levels of iron might increase shortness of breath and fatigue.
In this study the investigators aim at addressing potential relationships between iron stores and glucose homeostasis. Iron (i.e. Ferric Carboxymaltose) will be perfused to pre-menopausal, iron-deficient non-anaemic women suffering from a chronic fatigue syndrome and parameters related to glucose homeostasis, parameters related to metabolic syndrome and inflammation will be measured before and after the intervention.
When immediate clamping of the umbilical cord (ICC) occurs at birth, 20 to 30% of the fetal-placental blood volume is left behind in the placenta. Preliminary results from our current study comparing effects of ICC versus placental transfusion from delayed cord clamping (DCC) show that infants who have DCC have higher ferritin levels at 4 months of age and more myelin in important regions of the brain. Our objective for this follow-up study is to see if the effects of placental transfusion persist to three and four years of age. The investigators plan to enroll only children who participated in the previous trial (Infant Brain Study/NCT01620008) at birth for assessments at three and four years of age. Assessments include MRIs and neurodevelopmental testing to examine cognitive, motor, visual, and behavioral outcomes. The proposed research addresses two central questions regarding the potential benefits of DCC on brain myelin development in children who were born healthy at term: 1. Does DCC result in increased brain myelin deposition at three and four years of age? and 2) Are DCC, iron stores, and brain myelin content in infancy associated with improved cognitive, motor, and socio-behavioral outcomes at three and four years of age?
The purpose of this study is to determine if patients with unexplained iron deficiency have underlying diseases processes such as celiac disease. It is hypothesized that selectively screening patients with unexplained iron deficiency will reveal previously undiagnosed etiologies, including celiac disease and other causes of iron malabsorption along with various sources of occult GI blood loss.
The hypothesis to be tested is whether treatment with intravenous iron (ferric carboxymaltose) will improve left-ventricular ejection fraction in patients with heart failure and iron deficiency as determined by cardiac magnetic resonance imaging.
This study is designed to assess, relative to placebo, the effects on the evolution of exercise capacity and symptomatic status of the addition of iron treatment with FCM (ferric carboxymaltose) to the basic regimen of ambulatory patients with stable symptomatic chronic CHF (congestive heart failure) and iron deficiency.
