Filter by: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.
We are performing the above prospective randomized trial in 1'000 patients undergoing cardiac surgery. The study will answer the question of whether preoperative treatment of anemia or iron deficiency indeed improves transfusion needs (primary outcome) and important clinical outcomes (secondary outcome) in a large group of cardiac surgical patients. The list of inclusion and exclusion criteria was deliberately chosen short so that this patient group largely reflects today's clinical practice . - Trial with medical product
Previous studies on iron absorption have focused on the effects on the addition of iron absorption enhancers like ascorbic acid and EDTA to a meal and more recently the enzymatic phytic acid removal through phytase. The investigators want here to investigate the effects of fat on iron absorption with and without the addition of exogenous phytase as a potential iron absorption enhancer in lipid nutrient supplements (LNS) products compared to micronutrient powder(MNP) products. Furthermore the investigators will evaluate the effects of Lipids- on iron absorption to induce the ileal brake by ingestion of a fat emulsion prior to a meal. Increasing the caloric density of a meal by increasing its fat content might enhance iron absorption by delaying gastric emptying, gastric acid secretion and increasing Fe stomach residence time.
Slow release iron capsules containing ferrous sulfate have been designed based on the gastric delivery system. Iron absorption from those capsules administered with and without meals will be measured using stable iron isotopes.
Heart failure (HF) is a major global public health issue which also affects Asia. Data from the National Registry of Disease in Singapore shows a 9.4% rise in HF admissions in public hospitals from 2008 to 2009 (4140 to 4530). Anaemia (low blood Haemoglobin level) is a common problem occurring in HF, ranging from 14% to 56% in outpatient registries and clinical trials. Anaemia exacerbates the basic symptoms of HF of dyspnea and exercise intolerance, thereby reducing quality of life (QoL). However, recent approaches aimed at improving and normalizing Haemoglobin have been unsuccessful.Novel approaches are required to address this problem. Iron deficiency (ID) is a well-understood cause of anaemia. ID without overt anaemia may be present in HF patients. A recent study by Jankowska et al published in 2010 of 546 HF patients showed a 37% prevalence of ID, regardless of Haemoglobin level. This was associated with worse outcomes including impaired exercise capacity. The presence of ID indicates a higher likelihood of deteriorating and dying early. A landmark study published in the New England Journal of Medicine (The Ferinject Assessment in Patients with Iron Deficiency and Chronic Heart Failure (FAIR-HF) study) showed that HF patients who were treated with IV iron in the form of Ferric Carboxymaltose (FCM) had better outcomes, including improved exercise capacity, overall function, and quality of life. There is a lack of contemporary data on ID in HF patients in Asia, including data on treatment with this novel IV iron FCM. Hypothesis We hypothesise that treating ID in HF patients in Asia using FCM will improve outcomes including exercise capacity, quality of life, overall functional status, and the need to be hospitalised for complications arising from HF.
The primary purpose of the study is to evaluate the effect of IV iron isomaltoside 1000 compared with placebo on Hb in first-time female donors with p-ferritin below 30 µg/L
Slow release iron capsules have been designed based on the gastric delivery system. Iron absorption from those capsules administered with and without meals will be measured using stable iron isotopes.
This is a pilot study designed to compare the tolerance of ionic iron (ferrous sulphate) with heme iron polypeptide. Subjects will take one week of one product followed by a week with no product followed by a week with the other product. Subjects will complete a daily diary to assess side effects. Hypothesis: Heme iron polypeptide is associated with fewer gastrointestinal side effects than ionic iron.
On exposure to hypoxia (low oxygen) the normal response is for pulmonary arterial systolic blood pressure (PASP, blood pressure through the lungs) to increase. We have previously shown that raising iron by giving an infusion of iron into a vein reduces this pressure rise and that lowering iron by giving a drug that binds iron, magnifies this response. This is potentially a clinically important observation since iron-deficient people may be at increased risk of pulmonary hypertension if exposed transiently or permanently to hypoxia due to lung disease or residence at high altitude; furthermore if this were true then intravenous iron could be an important treatment in this patient group in the event of hypoxic exposure. The observed effects of iron on PASP are likely to be because iron levels affect oxygen sensing. Low iron levels make the body behave as if exposed to low oxygen by inhibiting the breakdown of the family of oxygen-sensing transcription factors, 'hypoxia inducible factor' or HIF. This includes one of the body's normal responses to low oxygen levels - raising blood pressure through the lungs. This study will answer the question (1) do iron-deficient volunteers have a greater rise in PASP with hypoxia than those who are iron-replete, and (2) does giving intravenous iron cause a greater reduction in the rise in PASP in those who are iron-deficient than iron-replete? The purpose of this study is not to test the safety or clinical efficacy of iron which is already known.
Problematic and state of the art Obesity and its associated non communicable diseases (NCDs) are rising rapidly in middle income countries, such as those in the Maghreb (North Africa). This progression is related to the context of a nutrition transition (changing food and physical activity environment) and profound changes in technological advances and in society. These societies and their health systems are insufficiently prepared for this evolution, which has enormous health and socioeconomic consequences. In the context of limited resources, the priority has been given on an international level to prevention. But several problems arise: - these countries are still confronted by undernutrition in terms of micronutrient deficiencies, which coexist with obesity and NCDs, including at a family level and also individual level. Known as the 'double burden', this coexistence is relatively new and has been rarely documented until recently. Educational measures could be ineffective in a society where cultural norms do not recognise obesity and where changes in lifestyle are possibly not seen as acceptable. As well as information about citizen's knowledge of risk factors, data on their perceptions and attitudes are indispensable. Policies that involve changing the 'obesogenic' environment that individuals occupy is a priority. Objectives of the project Overall aim: to contribute to the development of preventive strategies for obesity and chronic NCDs in the context of a nutrition transition. Specific objectives: characterise the nature and size of the double burden (obesity/undernutrition) in regions, families and individuals; estimate the prevalence of biological and behavioural risk factors; characterise the psycho-sociocultural determinants of behaviour.
