Assessing Dietary Intake of Selected Food Components Using Short Questionnaires

The aim of the study is to validate short questionnaires for assessing dietary intake of selected food components, with a focus on dietary fibre and iron. Two internationally developed short questionnaires (FiberScreen \[for dietary fibre\] and IRONQ-FFQ \[for iron\]) were adapted to the Slovenian context and will be compared with the standard 24-hour dietary recall method.

Impact of Intravenous Iron Repletion On Mechanisms of Exercise InTolerance in HFpEF (IRONMET-HFpEF)

The primary objective of this study is to determine if the correction of functional iron deficiency by administering a single dose of intravenous iron (ferric derimaltose or Monoferric®) in participants with heart failure with preserved ejection fraction (HFpEF) will improve exercise capacity as measured by the change in peak oxygen uptake (peak VO2) from baseline to 12 weeks.

Darbe Plus IV Iron to Decrease Transfusions While Maintaining Iron Sufficiency in Preterm Infants

In this phase II trial, the investigators overarching goal is to demonstrate the feasibility and potential benefit of darbepoetin (Darbe) plus slow-release intravenous (IV) iron to decrease transfusions, maintain iron sufficiency and improve the neurodevelopmental outcomes of preterm infants. Investigators hypothesize that in infants \< 32 completed weeks of gestation, combined treatment with Darbe plus Ferumoxytol (FMX) or Darbe plus low molecular weight iron dextran (LMW-ID) will: 1) be safe, 2) decrease or eliminate transfusions, 3) maintain iron sufficiency, 4) result in higher hematocrit and 5) improve neurodevelopment. Investigators further hypothesize that when compared to oral iron supplementation (standard care), IV iron will be better tolerated, with less effect on the gastrointestinal (GI) microbiome

Effect of Oral sucRosomIal Iron on exerciSE Capacity and Quality of Life in Patients With Heart Failure

The goal of this study is to investigate the effect of oral sucrosomial iron on exercise capacity and quality of life in patients with heart failure (HF) and iron deficiency (ID). The main question the study aims to answer is whether oral sucrosomial iron improved exercise capacity, assessed by six-minute walk test, and quality of life, assessed by Kansas City Cardiomyopathy Questionnaire, compared with placebo. One group of participants will receive treatment with oral sucrosomial iron and the other group will receive treatment with placebo.

PEPPI Study: Identification of Women at Risk for Placental Dysfunction

The main purpose of this study is to evaluate Fetal Medicine Foundation's pre-eclampsia risk calculator using maternal characteristics, first trimester serum placental growth factor (PlGF) and mean arterial pressure (MAP) in a Finnish general population. Condition or disease: pre-eclampsia, intrauterine growth restriction, polycystic ovary syndrome

Non-invasive Detection of Iron Deficiency in Obstetrics

Validation of non-invasive measurement of zinc protoporphyrin for detection of iron deficiency in pregnancy. In addition, the impact of iron deficiency on the incidence of postpartum depression, restless legs syndrome, obstetric complications and quality of life will be examined.

Effects of IV Iron Replacement on Exercise Capacity in Individuals With Heart Failure

Patients with heart failure with reduced ejection fraction and iron deficiency will be randomized to either receive iron infusion or be in the control group. The study is looking at how iron replacement affects exercise capacity as measured by peak oxygen uptake.

Ferric Derisomaltose and Outcomes in the Recovery of Gynecologic Oncology: ERAS (Enhanced Recovery After Surgery)

Iron deficiency has been reported in approximately 35% of patients with a gynecologic malignancy. Blood transfusions are known to be immunosuppressive and carry immediate and long-term risks. Pre-operative blood transfusion in gynecologic oncology patients is associated with higher rates of surgical site infection, length of stay, composite morbidity, cancer recurrence, and mortality. Pre-operative intravenous iron formulations have been shown in benign gynecology and other surgical specialities to increase pre-operative hemoglobin and decrease post-operative transfusion rates. This is a randomized double-blinded clinical trial evaluating the effects of treating patients undergoing gynecologic oncology surgery with intravenous ferric derisomaltose to correct pre-operative iron-deficiency anemia. The 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.

Challenges in Achieving Adequate Dietary Status of Women

The aim of the study is to investigate the dietary habits of women of reproductive age (20-49 years). We aim to obtain epidemiological data on the intake and adequacy of key macronutrients and micronutrients, as well as to explore associations with various health indicators. Additionally, we will focus on the nutritional status of subgroups with specific dietary practices, such as vegetarians and vegans.

Iron Isomaltide for Iron-deficiency Anemia Patients With Locally Advanced Nasopharyngeal Carcinoma

Primary purpose： To evaluate the difference of hematopoietic response rate at 1 month after concurrent chemoradiotherapy between iron isomaltide and oral iron supplement for treating iron-deficiency anemia patients with locally advanced nasopharyngeal carcinoma. Secondary purpose: To evaluate the difference of hematopoietic response rate, tolerance, acute side effects, qualtiy of life at 2 months and 3 months after concurrent chemoradiotherapy between Iron Isomaltide and oral iron supplement for treating iron-deficiency anemia patients with locally advanced nasopharyngeal carcinoma.

Effects of Intravenous Administered Iron in Non-anemic Iron Deficient Patients With Colorectal Cancer

This double-blinded clinical randomized trial with a 1:1 recruitment ratio between placebo and the active group will aim to investigate the effects of intravenously administered iron in non-anemic iron deficient patients on physical capacity, immunological cells and their function prior to surgery. A total of 134 patients with colorectalcancer will be included in the study. Study outline: After initial inclusion the patient will undergo baseline testing with cardiopulmonary exercise test (CPET), then followed by an infusion of a weight dependent dosage of iron(III)isomaltoside or placebo. Then at the closest possible time to the surgery the patient will have drawn bloodwork and be re-tested by (CPET). The patient will be followed after surgery with evaluation of several outcomes including quality of recovery and complications. Further, the effects of the intervention on the patients immune function will be evaluated by two different methods: 1) by changes in neutrophil-to-lymphocyte ratio between baseline and preoperative bloodwork and 2) by evaluation mRNA expression in the tumor specimen by the Nanostring pancancer immune panel
