Anemia is a common complication among cancer patients and is negatively associated with overall prognosis and therapeutic outcomes. The purpose of this study is to see if giving a dose of iron prior to any standard of care chemotherapy treatment will affect the cells that are believed to make treating melanoma harder, making melanoma more responsive to the standard of care immunotherapy.
The FeMicrobiome study will evaluate gut microbiome features and their relationships with dietary iron absorption in healthy adults. The investigators hypothesize that (1) the gut microbiota can be shaped by the heme and non-heme Fe content of the diet and that (2) this will influence individual variation in dietary Fe absorption.
The primary aim of this randomized trial is to assess the efficacy of IV Ferric Derisomaltose vs Oral Iron in the management of women with severe Iron Deficiency Anemia due to Uterine Bleeding in the emergency department.
This study investigates whether intravenous (IV) iron \[Feraheme (ferumoxytol) injection)\] is a better treatment than oral iron pills (ferrous sulfate) for correcting anemia in women who have heavy menstrual bleeding and anemia. Investigators will study whether women's blood counts respond better, respond more quickly, and if women prefer the IV treatment or the oral treatment. Women who have heavy menstrual bleeding and anemia will be randomly assigned to receive treatment with either oral iron pills or IV iron infusions. Investigators will then check whether and how quickly the anemia improves, and survey participants on how satisfied they were with the treatment.
This is a trial with an observational and an interventional arm, in patients with moderate to severe anemia and control subjects. The main purposes of this study is to phenotype the scope of neurocognitive deficits from iron deficiency anemia (IDA) in adult women, determine derangements in cerebral perfusion, vascular reactivity, functional connectivity, and blood brain barrier permeability in adult-onset IDA and relate them to neurocognitive deficits, as well as determine the reversibility and durability of both the physiologic and neurocognitive derangements by iron replacement therapy. All eligible subjects will be asked to provide informed consent before participating in the study.
Diagnostic modalities for the evaluation of small bowel pathology include video capsule endoscopy (VCE), antegrade and retrograde device-assisted enteroscopy, CT and MR enterography (1). Despite VCE being the first-line evaluation modality, it lacks interventional capability. Deep enteroscopy (DE) allows tissue sampling and other therapeutic interventions with real-time endoscopic assessment. DE is usually performed with specific endoscopes (balloon-assisted device or spiral overtube) making it time consuming and there is limited availability since special instruments and accessories are required.(1,2) The through-the-scope (TTS) balloon system consists of a balloon catheter designed for anchoring in the small bowel, inserted through the instrument channel of a standard colonoscope.(3) The catheter is advanced, the balloon is inflated and anchored in the small intestine and the endoscope slides over the guiding catheter to the inflated balloon. The most common indications for DE are obscure GI bleeding, iron deficiency anemia, abnormal capsule endoscopy and chronic diarrhea. As compared to spiral, single-or double-balloon enteroscopy, TTS (NaviAid, SMART Medical Systems Ltd, Ra'anana, Israel) is a simpler technique, which requires less investment in infrastructure. The balloon catheter is advanced blindly in front of a standard adult colonoscope as it bends around the curves of the small bowel. To prevent perforation/trauma the catheter is fitted with a soft silicone tip which easily bends under pressure. Insertion depth can be calculated during the withdrawal of the enteroscope. The Aim of the study: To compare the depth of maximal ileal insertion between through-the-scope balloon enteroscopy (NaviAid) with enteroscopy using the adult colonoscope (Olympus CF-190) alone, in the same patient, in a prospective cohort at University Medical Center of El Paso, Texas.
This is a randomized, controlled multi-site trial of iron therapy in pregnancy. The purpose of this research is to see if second trimester initiation of intravenous (IV) iron therapy is better than oral iron therapy for treatment of anemia in pregnancy by improving blood count, quality of life and reducing side effects.
