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. This review article aims to provide an overview of the current evidences on the role of iron in CRC, discussing the potential mechanisms by which iron may affect CRC development and progression, as well as the implications for prevention and treatment. This review tries to focus on the following aspects: an introduction to iron and its role in CRC, role of heme and non-heme iron in CRC, dietary patterns, nutrition, and CRC, iron overload in CRC, iron deficiency and its role in CRC especially in surgery outcome and iron therapy and blood transfusion in CRC.

Periodontitis is a significant global public health issue associated with the onset and progression of various systemic diseases, thereby requiring additional research and clinical attention. Although ferroptosis and cuproptosis have emerged as significant areas of research in the medical field, their precise roles in the pathogenesis of periodontitis remain unclear. We aim to systematically summarize the current research on ferroptosis and cuproptosis in periodontal disease and investigate the roles of glutathione pathway and autophagy pathway in connecting ferroptosis and cuproptosis during periodontitis.

The north-eastern part of Karnataka lies on the Deccan Plateau of the South Indian Peninsula, characterized by black soil. This region is known for its mineral resources, including a gold ore mine in Hatti (Raichur District), an iron ore mine in Toranagallu (Bellary District), and uranium deposits in Gogi (Yadgir District). However, the soil in this area is deficient in iodine, leading to iodine deficiency disorders such as goiter and hypothyroidism.

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.
