Filter by:The aim of this study is to examine the beneficial effects of Danggui Buxue Tang on blood biochemical parameters in male recreational runners.
The goal of this pilot study is to test whether the microbiome is affected by intravenous iron repletion.
This pilot study is designed to investigate (1) whether getting iron treatment affects iron in the brain and (2) how getting iron treatment affects brain functions when it is performing specific cognitive tasks. By cognitive tasks, it means tasks that involve perceiving, representing, or assessing things. The specific cognitive tasks used here will involve tests of memory and processing speed.
Infants and young children in sub-Saharan Africa have high rates of iron deficiency anemia (IDA), which adversely affects their growth and cognitive development. In-home iron fortification of complementary foods using micronutrient powders (MNPs) reduces risk for IDA by ensuring that the iron needs of infants and young children are met without changing their traditional diet. In order to optimize iron absorption timing of MNP consumption might as well be important. This is because hepcidin, a key regulator of systemic iron balance, shows a circadian increase that may influence morning versus afternoon iron absorption from the MNP. Furthermore, a single dose of iron can increase hepcidin levels and potentially inhibit iron absorption from a second dose, consumed close in time to the first dose. To determine the difference between i) morning versus afternoon iron absorption and ii) consecutive versus alternate day iron absorption, investigators will enrol 20 infants from Kwale County aged 6-14 months and conduct two studies. In study 1, infants will consume 2 test meals consisting of maize porridge containing isotopically labelled Ferrous Sulphate in the morning and afternoon on 2 days. In study 2, infants will consume 3 test meals consisting of maize porridge containing isotopically labelled Ferrous Sulphate on two consecutive days and 1 alternate day. In both studies, fourteen days after the last test meal administration, a whole blood sample will be collected by venipuncture for iron isotopic analysis. Iron and inflammation status parameter will be determined at baseline and endpoint. Hepcidin concentrations will be measured before the morning and afternoon meals (study 1) and after second consecutive meal (study 2). Knowing the effect of time on the expected iron absorption will inform decisions on the ideal timing of MNP to cover the infant's requirement for absorbed iron.
Study to Compare Ferric Carboxymaltose With Placebo in Patients With Acute Heart Failure and Iron Deficiency (Affirm-AHF)
Primary Hypothesis - The 24-hour post-transfusion RBC recovery of units obtained from donors exhibiting iron-deficient erythropoiesis will not meet FDA standards for clinical use. - The 24-hour post-transfusion RBC recovery of units obtained after intravenous iron repletion will improve significantly and will meet FDA standards for clinical use.
The main objective of the study is to compare the impact of oral ferric citrate compared to standard of care oral ferrous sulfate on serum iron, percent transferrin saturation, ferritin, hepcidin and hemoglobin levels in individuals with moderate to severe chronic kidney disease (CKD) and absolute iron deficiency.
This retrospective study is a more extensive, confirmatory analysis of the cognitive and functional outcomes initially seen in 2 groups of MCI/dementia patients in Springfield, MA and compares specialized dementia care and a comprehensive treatment approach versus usual care delivered in a non-specialist setting. The first group of patients (n= 328) was seen by a dementia specialist, who utilized a standardized assessment and treatment protocol (CNS). This included comprehensive identification and treatment of hypoxia, sleep-disorders, and other cognitively-impairing metabolic conditions as well as maximally- dosed FDA-approved medications for dementia, depression, and PBA. The second group of patients (n= 280) was seen by non-dementia specialists in the community and received usual care which did not include comprehensive assessment or treatment of underlying metabolic derangements or maximal utilization of currently available medications. This study, evaluating date from a larger cohort (n>800) of specialist-treated cognitively-impaired patients, will further examine the hypothesis that a comprehensive dementia treatment protocol yields cognitive stabilization and/or improvement using already available dementia drugs when compared with usual community care.
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.
Iron is one of the most vital elements in humans as it plays a role in physiological functions such as transferring and storing oxygen, transporting electrons and catalysing numerous reactions, from oxidative metabolism to cellular proliferation. Iron deficiency can be attributed to poor absorption that leads to insufficient iron to meet body requirements. Oral iron supplements have been extensively used to treat iron deficiency and iron deficiency anaemia. However, the use of iron compounds in fortifying foods is one of the best practical approach to combat iron deficiency, while improving diet and food pattern involves long-term goal which can be challenging. Vitamin D has recently been shown to affect hepcidin levels, which in turn has effects on iron status but there are a limited number of studies investigating the hepcidin profile in humans following iron supplementation, and few data are available, especially in humans, despite its role as a primary iron absorption and homeostasis regulator. Although several studies have been carried out using iron fortified products, there is limited data on the potential effect of vitamin D on iron metabolism amongst iron deficient women in particular. Therefore, the present study aims to investigate the effect of vitamin D3 supplementation (1500 IU) consumed with iron fortified breakfast cereals on haematological indicators and hepcidin response in iron deficient women.
