INTRODUCTION: Erythropoietin (EPO) is a commonly used option in the treatment of chemotherapy-induced anaemia (CIA). However, ∼30-50% of patients fail to achieve an adequate response after initial treatment. Prior studies have demonstrated that intravenous iron might synergistically improve therapeutic response to EPO treatment in this patient population. METHODS AND ANALYSIS: We will perform this multicentre, randomised, open-label, parallel-group, active controlled non-inferiority study to compare the two combination therapies of EPO plus intravenous iron regimen versus doubling the dose of EPO in patients with CIA who have an inadequate response to initial EPO treatment at a routine dose...

BACKGROUND: Quantitative susceptibility mapping (QSM) and R2* relaxation rate mapping have demonstrated increased iron deposition in the substantia nigra of patients with idiopathic Parkinson's disease (PD). However, the findings in other subcortical deep gray matter nuclei are converse and the sensitivity of QSM and R2* for morphological changes and their relation to clinical measures of disease severity has so far been investigated only sparsely. METHODS: The local ethics committee approved this study and all subjects gave written informed consent...

Recent cases involving biosamples taken from indigenous tribes and newborn babies reveal the emptiness of informed consent. This venerable doctrine often functions as a charade, a collective fiction which thinly masks the uncomfortable fact that the subjects of human research are not actually afforded full information regarding the types of research that may be contemplated, nor do they provide meaningful consent. But if informed consent fails to provide adequate protection to the donors of biological materials, why not turn to principles of property law? Property is power, yet current law permits everyone except for those who donate biological materials to possess property rights...

BACKGROUND: In research ethics, the most basic question would always be, "which is an ethical issue, which is not?" Interestingly, depending on which ethics guideline we consult, we may have various answers to this question. Though we already have several international ethics guidelines for biomedical research involving human participants, ironically, we do not have a harmonized document which tells us what these various guidelines say and shows us the areas of consensus (or lack thereof)...

Serum ferritin is an excellent marker for total iron content in the body and is essential for the diagnosis of iron deficiency or iron overload. Recently, a simple and rapid method, which utilizes immunochromatography for the quantification of serum ferritin, was developed. However, the range of measurement in previous reagents was limited (10-500 ng/mL). This range is rather narrow and is not fully helpful for the diagnosis of iron overload which sometimes occurs as a result of prolonged transfusions, or for monitoring iron contents during iron chelation therapy against iron overload...

OBJECTIVES: There is a need to remove excess iron with iron chelation therapy (ICT) to avoid the serious clinical sequelae associated with iron overload in patients with beta thalassemia major (BTM) and sickle cell anemia (SCA). Due to the effects of the diseases and their treatments, ICT is still a major reason for unsatisfactory compliance. The aim of this single-center observational study was to evaluate the quality of life, clinical effectiveness, and satisfaction in pediatric and adult patients with BTM and SCA receiving deferasirox (DFX) chelation therapy...

The Collegium Ramazzini reaffirms its long-standing position that responsible public health action is to ban all extraction and use of asbestos, including chrysotile. This current statement updates the Collegium's earlier statements with a focus on global health dimensions of asbestos and asbestos-related diseases (ARD). The ARD epidemic will likely not peak for at least a decade in most industrialized countries and for several decades in industrializing countries. Asbestos and ARD will continue to present challenges in the arena of occupational medicine and public health, as well as in clinical research and practice, and have thus emerged as a global health issue...
