Filter by:Lactoferrin (Lf) is a mammalian cationic iron binding glycoprotein belonging to the transferrin family which was discovered 70 years ago, and isolated simultaneously from human and bovine milks in 1960. It is widely distributed in all biological fluids and is also expressed by immune cells, which release it under stimulation by pathogens
Approximately 20% of patients undergoing elective orthopaedic surgery are anaemic. When not identified and treated before surgery, this can lead to requiring blood transfusions, which brings additional expenses, time and inconvenience to the patient.It is recommended that preoperative assessment involves investigation and where possible, treatment of anaemia. The timescale between assessment and surgery makes it difficult to comply with guidelines without postponing surgery. This study will investigate adult patients scheduled for elective orthopaedic surgery, where a full blood count is to be taken as part of routine care. A paired non-invasive reading of their blood will be taken. It will be conducted at The Royal Infirmary, Edinburgh. This device is not in use within the department currently but has been given free of charge for the study. There are no restrictions placed on the device except that it is not accurate for measuring haemoglobin <8g.dL. Participant care will only be determined by results from the laboratory assay as per routine care, not the noninvasive device. The device is CE marked for haemoglobin determination. Masimo (manufacturer) have released results in the accuracy of their monitor but with very little other information, for example, study population or precision. This study aims to answer how accurate and precise non-invasive measurements are in patients scheduled for orthopaedic surgery (there are no studies with these results) and whether anaemia can be identified earlier in the patient pathway i.e. an anaemia screen at time of surgical listing, therefore leaving ample time for treatment and optimisation of care. The data from the study will not be shared with Masimo. There is ongoing work towards introducing and piloting a new pre-operative triage system where optimisable conditions e.g. anaemia are identified at the time of listing. This study would aid this work.
This study is a nonrandomized, single arm, open-label study stratified by iron-deficiency status.
To combat iron deficiency in Low and Middle-Income Countries, sustainable food-based solutions have to be implemented to serve populations, not only individuals. One solution is the introduction of iron biofortified staple crops on market level. Before market level introduction, the bioavailability of iron in the new biofortified Irish Potato (IP) breed needs to be assessed. In this study the investigator compares the fractional and total iron absorption after extrinsic stable isotope labelling of the new biofortified high iron IP variety and a normal market level IP variety. The study is conducted in Peruvian women of reproductive age with marginal iron status.
Hypoperfusion, hypoxia and ischemia occurs in circulation as a result of anemia. All of these situations lead to oxidative stress and endothelial dysfunction in the organism. In this study, the investigators aimed to investigate the oxidant-antioxidant balance and asymmetric dimethylarginine (ADMA) levels in patients that have symptomatic anemia in need of erythrocyte suspension (ES) transfusion. To the best of the investigators knowledge, there have been few studies in the literature on anemia and total oxidant, total antioxidant and ADMA levels. We aimed to observe changes in oxidative - antioxidant ADMA levels before and after ES transfusion.
The renal Doppler resistive index (RRI) is a noninvasive tool that has been used to assess renal perfusion in the intensive care unit (ICU) setting. It is associated with the occurrence of acute kidney injury (AKI). Many parameters have been described as influential on the values of renal RI. Red blood cell (RBC) transfusion were shown to be able to increase renal oxygenation in animal model, whereas crystalloid resuscitation did not. We sought to describe the different effect of crystalloids infusion and RBC transfusion on renal blood flow, as evaluated with doppler ultrasound
This is an open-label, randomised, multicenter, Mircera-controlled, parallel-group, Phase III study to determine whether subcutaneous administered efepoetin alfa is as effective and well tolerated as subcutaneous Mircera for anaemia correction and maintenance in erythropoiesis stimulating agent (ESA)-naïve subjects who have CKD and are not on dialysis. ESA prior users who have stopped using ESA at least 12 weeks till screening will also be eligible for this study provided they fulfil all the subject entry criteria.
Mixed venous oxygen saturation is known to reflect oxygen delivery and, thus, is frequently monitored in patients undergoing cardiac surgery. Factors that affect mixed venous oxygen saturation include hemoglobin level, arterial oxygen saturation and arterial oxygen partial pressure. Among them, arterial oxygen partial pressure is known to have minimal effect on oxygen delivery compared to hemoglobin and arterial oxygen saturation. However, some argues that in certain clinical setting, such as anemia which is very common in cardiac surgery patients, the contribution of plasma (arterial oxygen partial pressure in this case) to oxygen delivery becomes more significant. Therefore, we planned to perform a pilot clinical trial to observe the change of oxygen delivery, which would be reflected in mixed venous oxygen saturation and cerebral regional oxygen saturation, according to hemoglobin level.
This is an open-label study to understand the safety and tolerability of AXA4010, a novel composition of amino acids in adult and adolescent subjects with sickle cell disease over 12 weeks. The study also assesses the effects of this amino acid composition on the structure and function of the vascular system. Physiological effects on structure and function will be assessed by Magnetic Resonance Imaging (MRI) to assess blood flow in the brain and kidneys and the 6-Minute walk with pulse oximetry. Changes in blood biomarkers of inflammation will also be assessed.
Iron deficiency anemia is a global health problem and the most common cause of anemia worldwide. Patients with iron deficiency and Iron deficiency anemia can present with a multitude of symptoms including fatigue, dyspnea on exertion, dysphagia, pallor, palpitations, headaches, tinnitus, taste disturbance and pica. Oral iron supplementation is associated with increasing hemoglobin in multiple studies in women, pregnant women and elderly patients. However, the optimal dose and frequency of oral iron supplementation for treatment remains unclear. The current proposed study attempts to address this gap in the literature.
