In 2005, colorectal surgery in France represented nearly 40,000 procedures per year, of which 80% were scheduled and 70% were for carcinological purposes. Overall postoperative mortality was estimated at 3.4%, morbidity at 35% and average length of stay at 18 days. In addition, the number of newly diagnosed cases of colorectal cancer was 44,872 in 2017, making it the second leading cause of cancer in women and the third in men. The implementation of colorectal Enhanced Rehabilitation After Surgery (EARS) programs has resulted in a significant reduction in length of stay due to an approximately 50% decrease in postoperative complication rates and a faster return of patients to independence. However, despite the integration of RASC into routine practice, morbidity remains high with an estimated complication rate of 15-20%. The persistence of a high complication rate despite the rehabilitation measures can be explained in part by factors present preoperatively that impair postoperative recovery, such as the existence of comorbidities, low functional capacity, the presence of martial or nutritional deficiencies or glycemic imbalance. Links between the presence of these different "deficits", which may coexist, and postoperative morbidity and mortality have already been shown. Anemia is common in preoperative colorectal surgery and affects approximately one in two patients with cancer. In case of preoperative anemia, the frequency of postoperative complications and the length of stay are increased. Under these conditions, preoperative correction of anemia could facilitate postoperative recovery and reduce the incidence of postoperative complications. In colorectal cancer, anemia is the consequence of an absolute martial deficiency due to iron losses from bleeding and a functional martial deficiency due to decreased availability of iron for erythropoiesis due to inflammation. Correction of preoperative anemia is usually based on 2 types of molecules: iron and erythropoiesis stimulating agents. Erythropoiesis-stimulating agents are not recommended to correct anemia in cancer patients not receiving chemotherapy. Iron can be given orally or intravenously. Intravenous administration is more effective than oral administration in patients with colorectal cancer to correct preoperative anemia. In patients undergoing colon cancer surgery outside of a RAAC program, preoperative iron infusion appears to decrease the incidence of postoperative complications, improve the quality of postoperative recovery, and reduce length of stay. These gains do not appear to be related to correction of preoperative anemia, since preoperative intravenous iron increases hemoglobin levels by only 0.8 g/dl, on average. And, insufficiently to reduce the rate of postoperative transfusion in abdominal or general surgery. Also, the benefits observed with preoperative iron infusion seem to be more related to the direct effects of iron on cardiac and skeletal muscle than by correction of anemia. Since 2016, all patients undergoing scheduled colorectal surgery at the Paris Saint Joseph Hospital Group benefit from the application of a RAAC program. If we do not take into account patients who die during hospitalization (≈ 2%) and patients transferred to Follow-up and Rehabilitation Care (SSR) (≈15%), the impact of the application of a RAAC program is easily measured with the length of stay. Indeed, reducing the frequency of postoperative complications and improving the speed of postoperative recovery translates into reduced lengths of stay. Today, the average length of stay for all patients undergoing colorectal surgery at Saint Joseph Hospital is 7.5 days. The length of stay is longer (8.7 days) in patients with anemia preoperatively compared to those without anemia (7 days). Since 2017, anemic patients scheduled for colorectal surgery, have received intravenous iron infusion preoperatively at Paris Saint Joseph Hospital.
Iron deficiency is defined by insufficient tissue iron stores and anemia is the ultimate stage of iron deficiency. Anemia should never be neglected in an elderly subject because it is associated with an increase in mortality, but also with a increased morbidity in terms of complications Apart from anemia, iron deficiency is common and constitutes a factor of poor prognosis in diseases chronic, all pathologies very frequently found in the elderly. It is the origin of the deterioration in the general condition of patients, their re-hospitalization or even the progression of their pathology. In this context where elderly patients also present a certain number of comorbidities including the pathologies mentioned previously, it is important to better diagnose the deficiency martial in the elderly patient.
As a follow-up to the RAPIDIRON Trial (NCT05358509), this study will follow the previously randomized mothers as well as their offspring after birth to assess neurodevelopmental, hematologic, and health outcomes. The study's overarching goal is to determine if the offspring born to RAPIDIRON Trial mothers in the intravenous iron groups, compared to the oral iron group, will achieve superior neurodevelopment, iron stores, and growth at specific time points during the first three years of life. Differences will be assessed between offspring based on the iron deficiency anemia (IDA) treatment of the mother.
One of the most common nutritional deficiencies worldwide is iron deficiency. Iron deficiency is considered the main cause of anaemia in developing countries, including those in South America. The most recent surveys report that the prevalence of anaemia is as high as, 40 and 25% in Peru. Populations living at higher altitudes may have higher iron requirements, as body iron is naturally increased in long-term high-altitude residents to compensate for the lower oxygen in the air at high altitudes. However, the effects of chronic exposure to high altitude on iron status, body iron compartments and dietary iron requirements are incompletely understood. The primary objective of the proposed research is to determine iron bioavailability of iron from biofortified potatoes at different altitudes in populations of Andean descent. Human trials will be undertaken with volunteers in the Huancavelica region of Peru (elevation: 3676 meters) as well as in Lima (elevation close to sea level). The aim is to assess the effect of altitude on the absorption from a promising iron biofortified potato cultivar. These trials require incorporation of iron stable isotopes into the meals of the bio fortified potato and the analysis of the isotopes in subsequent blood (red blood cells) samples. Stable iron istotopes are considered the golden standard to assess human iron absorption and can be safely used as tracer substances in humans. The objective of the study is to compare, in volunteer females of childbearing age, the bioavailability of iron from bio-fortified potatoes in two locations of different altitudes and quantify the effect of altitude on iron bioavailability from a potato meal consumed over 5 consecutive days.
The study will be conducted by the Indonesia Nutrition Association that led by a Principle Investigator and supported by the study team consisted of Nutritionists. The aims of the study are to reduce iron deficiency by increasing iron intake in children 1-3 years by providing interventions in the form of increasing iron intake from growing up milk for four months and nutrition education for the intervention group and nutrition education only for the control group.
Iron deficiency has been reported in up to 35% of patients with a gynecologic malignancy. These patients often require surgical intervention to determine the stage and to treat their illness. Blood transfusions occur in approximately 14% of these surgeries and carry immediate and long-term risks, including surgical site infection, cancer recurrence, and increased surgical length of stay. Intravenous iron formulations have the potential to rapidly correct anemia in patients with gynecologic malignancy and potentially decrease blood transfusion and complications following surgery. This prospective, randomized, placebo-controlled, double blind study aims to assess the effectiveness of preoperative ferric derisomaltose/iron isomaltoside compared to placebo in correcting preoperative hemoglobin in patients undergoing surgery for gynecologic malignancy. The primary outcome is to assess the effectiveness of this formulation on pre-operative hemoglobin, and the feasibility of a larger, outcomes based, study in the future. Exploratory outcomes are to assess the effect of preoperative intravenous iron on surgical length of stay, complications, and patient-reported quality of life.
Double blind, placebo controlled, multicenter randomized trial in pregnant women in the U.S. (N=746) to test the central hypothesis that IV iron in pregnant women with moderate-to-severe IDA (Hb<10 g/dL and ferritin<30 ng/mL) at 13 - 30 weeks will be effective, safe and cost-effective in reducing severe maternal morbidity-as measured by peripartum blood transfusion-and will also improve offspring neurodevelopment.
Iron deficiency anemia is the most common systemic manifestation of Inflammatory Bowel Diseases (IBD)-Crohn's disease and ulcerative colitis. Iron deficiency with or without anemia poses a diagnostic and therapeutic challenge due to chronic gastrointestinal blood loss and the inflammatory nature of IBD. Recent illumination of iron metabolism has brought attention to the systemic iron regulator-hepcidin, a peptide hormone that regulates intestinal iron absorption and systemic iron availability. Elevated hepcidin is associated with oral iron malabsorption in IBD. This study aims to evaluate whether hepcidin concentration at baseline can predict response to oral and intravenous iron therapy in patients with IBD and concomitant iron deficiency with or without anemia.
The objective is to investigate the treatment of non-anemic iron deficiency (NAID) and the impact on development of anemia later in pregnancy. Anemia in the third trimester has been identified as a risk factor for maternal and fetal morbidity that might lead to mortality. Due to the high incidence of NAID in pregnancy, there is an opportunity for early screening and treatment to decrease progression to anemia. The primary aim of this study is to establish if treatment of NAID will result in higher third trimester hemoglobin values and decrease incidence of anemia at term.
