Purpose: To increase awareness of nurse practitioners (NPs) about the dangers of iron overload and to review common hematologic conditions where transfusions are essential, iron mechanism and transport within the body, effects of iron overload on the body, and treatment options available. Finally, the process for development of a protocol for monitoring such patients will be introduced.
Data Sources: Review of existing literature, myelodysplastic syndrome guidelines, sickle cell guidelines, thalassemia guidelines.
Conclusions: Transfusions of packed red blood cells save lives. There are many hematologic conditions for which packed red blood cell transfusions are required as a result of bone marrow suppression. However, extended exposure to red blood cell transfusions places the patient at an additional risk of iron overload. Iron overload is a real concern for patients who become transfusion dependent, with increased risks of liver cirrhosis and cardiac arrhythmias.
Implications For Practice: NPs in all areas of practice can increase awareness of the dangers of transfusional iron overload, and become familiar with the treatment options available. Additionally, NPs can institute a monitoring program based on the protocol suggested here within their own practices to prevent poor outcomes for patients with transfusion-related iron overload.

Atherosclerosis (AS)-related cardiovascular disease and depression are often comorbid, with patients with cardiovascular disease facing an increased risk of depression, which worsens AS. Both diseases are characterized by oxidative stress and lipid metabolism disorders. Ferroptosis, a form of cell death characterized by iron overload and harmful lipid peroxide accumulation, is found in various diseases, including AS and depression.

However, data regarding the prevalence of anemia, iron deficiency, and iron overload among outpatients in real-world clinical settings remain limited. Moreover, the influence of specific diseases on iron kinetics within the CVD spectrum has not been fully elucidated.

Colorectal cancer (CRC) is a common and lethal malignancy that affects millions of people worldwide. Iron is an essential micronutrient that plays a vital role in various biological processes, but also has pro-oxidant and pro-inflammatory effects that may contribute to carcinogenesis. The relationship between iron and CRC is complex and influenced by multiple factors, such as dietary intake, absorption, storage, metabolism, and excretion of iron, as well as genetic and environmental factors that modulate iron homeostasis.

Oxidative stress in sporadic amyotrophic lateral sclerosis (ALS) has been evidenced by accumulation of oxidatively modified products of nucleic acids, lipids, sugars, and proteins in the motor neuron system of brains and spinal cords obtained at autopsy from the patients. We recently demonstrated soluble iron accumulation in activated microglia of sporadic ALS spinal cords. This finding could indicate that iron-mediated Fenton reaction is most likely to be responsible for oxidative stress associated with this disease.

Background: Iron overload cardiomyopathy is a significant cause of morbidity and mortality in transfusion-dependent thalassemia patients. Standard iron chelation therapy is less efficient in alleviating iron accumulation in many organs, especially when iron enters the cells specific calcium channels.
Aim: To validate our hypothesis that adding amlodipine to the iron chelation regimen is more efficient in alleviating myocardial iron overload.
