Active clinical trials for "Anemia"

The purpose of this study is to describe the prevalence of anemia and iron deficiency in pregnancy through a multi-center, prospective follow-up study . To explore the influence factors of anemia and iron deficiency in pregnancy; to explore the influence of anemia and iron deficiency in pregnancy on maternal and fetal outcomes.

Establishing a Data Base for Aplastic Anemia and Other Marrow Failure Syndrome

Both upper gastrointestinal endoscopy and colonoscopy are recommended in men and post-menopausal women with iron deficiency anemia. Due to lack of data on the yield of these endoscopies in young men, they are currently investigated as older men. The aim of this study is to evaluate prospectively the prevalence of various gastrointestinal lesions in young men with iron deficiency anemia. Our hypothesis is that the diagnostic yield of colonoscopy in young anemic men without gastrointestinal symptoms is very low, especially if a potential lesion is detected during upper gastrointestinal endoscopy. Therefore, this study will try to identify predicting factors regarding the yield of both endoscopies. Another purpose is to evaluate the outcome of patients with negative endoscopic results, during a follow-up of two years.

This is a sub-study nested into the existing NICHD Global Network for Women's & Children's Health Research Maternal Newborn Health (MNH) registry that is a prospective, observational population-based registry in Eastern Maharashtra, India. This study will assess the prevalence of iron deficiency anemia (IDA) and non-iron deficiency anemia (NIDA) in Eastern Maharashtra and will assess the association between both conditions and neo-natal and infant health outcomes (birth weight, gestational age at birth, weight-for-gestational-age z-score and infant hemoglobin concentration at 6 weeks). The investigators will also assess the relative strength of the association between anemia in the 1st trimester and 3rd trimester (after iron needs have increased but mothers may have been taking iron folic acid (IFA) supplements for several months) and infant health outcomes.

Anemia is a common pathology in geriatrics. According to the World Health Organization it affects 23.9% of subjects over 60 years in the world, and 8% of patients over 60 years in Europe. A prevalence that increases with the age and twice in individuals over 85 years.

Preoperative anemia is an independent risk factor for the need for allogeneic transfusion during surgery and increased postoperative morbidity. Treatment of preoperative anemia is recommended. However the type of preoperative anemias in elective hip- and knee surgery has only been sparsely studied. This observational study aims to investigate the incidence and type of anemias prior to elective hip- and knee arthroplasty.
