1. Como investigar um resultado de ferritina elevado?
Os casos de hiperferritinemia devem ser inicialmente investigados repetindo-se a dosagem de ferritina, além da dosagem de saturação de transferrina e hemograma com plaquetas. Deve-se investigar se o paciente tem história familiar de sobrecarga de ferro ou cirrose, história de reposição de ferro em excesso ou sobrecarga secundária a transfusões, u

2. Quando e como fazer a reposição de ferro endovenosa?
A reposição endovenosa de ferro é uma alternativa de tratamento da ferropenia quando houver:
•intolerância ao tratamento com ferro por via oral;
•falha de tratamento com ferro por via oral, geralmente por má absorção:
•gastrectomia;
•gastroplastia redutora;
•doença celíaca;
•gastrite atrófica;

3. Quais as causas de aumento da ferritina sérica?
A ferritina sérica elevada é encontrada em um grande espectro de condições, tanto genéticas como adquiridas 3. Pode estar elevada em condições como hepatopatias, alcoolismo, malignidades, doenças infecciosas e inflamatórias (ex artrite reumatoide), hipertireoidismo, infarto agudo do miocárdio, doença renal avançada e sobrecarga de ferro (hemos

4. Hereditary hemochromatosis beyond hyperferritinemia: Clinical and laboratory investigation of the patient’s profile submitted to phlebotomy in two reference centers in southern Brazil
Abstract Hereditary Hemochromatosis is a disorder characterized by iron deposition in several organs and hyperferritinemia. The most studied variants are linked to the HFE gene. In Brazil, surveys that characterize this population are scarce, with no sampling in the state of Rio Grande do Sul. Our objective is to carry out a data collection focusing on the p

5. Ultra-processed foods and the nutritional quality of the diet of Brazilian pregnant women
SUMMARY OBJECTIVE: The aim of this study was to evaluate the consumption of ultra-processed foods by Brazilian pregnant women and its association with the nutritional quality of the diet. METHODS: This is a prospective and cross-sectional study with food consumption data of Brazilian pregnant women from the 2017 to 2018 Family Budgets Survey (Pesquisa de O

6. Development of innovation routes for iron ore using high intensity magnetic separators
Abstract The mineral processing of low-grade iron ores commonly generates large volumes of slime, which are disposed as tailings. Modern mining requires strives to eliminate the use of tailings dams in a maximum effort to increase metallurgical recovery, the security and reduction of the operational cost. This research aims for the recovery of iron contained

7. HFE hemochromatosis: an overview about therapeutic recommendations
Abstract Hemochromatosis is currently characterized by the iron overload caused by hepcidin deficiency. Large advances in the knowledge on the hemochromatosis pathophysiology have occurred due to a better understanding of the protein of the iron metabolism, the genetic basis of hemochromatosis and of other iron overload diseases or conditions which can lead

8. Optical sorting technology for waste management from the Boukhadra iron ore mine (NE Algeria)
Abstract Mining processes in the iron ore mine of Boukhadra, Tebessa (NE Algeria) generated thousands of tons of mining wastes every year, which represents a real threat to the environment, leading to hazardous effects for the resident population of the region. The aim of this study is the selective sorting of the Boukhadra mining wastes for valorization. Th

9. Selective formation of neodymium phosphate from iron-neodymium magnet waste
Abstract Neodymium-iron-boron alloy, Nd2Fe14B, is used as a material for magnets. Neodymium is one of the valuable and expensive rare earth elements and is often recovered to reduce costs and environmental impact. Recently, a method for recovering neodymium as neodymium phosphate from mixed solutions was reported. This method was very useful because the main

10. Collector mixtures and their synergistic effect on quartz floatability
Abstract Sinergy is the interaction of two or more agents to produce a combined effect greater than the sum of their separate effects. Etherdiamine yields superior results for quartz floatability in a Hallimond tube and higher selectivity in the reverse bench scale cationic flotation of an iron ore, when compared to ethermonoamine. Blending these collectors

12. MLA and optical microscopy as complementary techniques to the iron ore geometallurgical studies
Abstract Mineral liberation is an important variable to be considered in the iron ore geometallurgical studies, especially since it provides information leading to the understanding of the ore’s behaviour in the beneficiation process, mainly when harder ores are concerned. Nowadays, the professionals and researchers in the mineral industry have been using
