Article Abstract
Background And Purpose: Serum ferritin, a well-established biomarker of iron status, has been inconsistently linked to stroke risk in previous studies. This meta-analysis aims to systematically evaluate the association between serum ferritin levels and the risk of stroke.
Methods: We conducted a systematic literature search across the PubMed and Embase databases to identify relevant studies. Studies meeting predefined eligibility criteria were selected, and relevant data were extracted. Statistical analysis was performed using Stata 12.0.
Results: Ten studies, including eight longitudinal and three cross-sectional, were included in our meta-analysis. Cross-sectional studies showed that stroke patients had significantly higher serum ferritin levels than controls. Longitudinal studies suggested a 22% increase in stroke risk in individuals with higher serum ferritin. Subgroup analysis indicated that further high-quality population-based cohort studies are warranted to validate these findings. Dose-response meta-analysis confirmed a positive association between serum ferritin levels and stroke risk.
Conclusion: This meta-analysis provides evidence of a positive association between increased serum ferritin levels and stroke incidence. While these results are promising, definitive conclusions cannot be drawn at this time. Therefore, additional robust, prospective cohort studies are imperative to substantiate this relationship.

Clinicians need a good understanding of available tools to diagnose iron deficiency (ID). Interpretation of commonly used laboratory tests can be challenging due to the dynamic nature of iron homeostasis and concurrent inflammation, which influence results. The misinterpretation of iron studies, inconsistencies in ID diagnostic guidelines, and low awareness of non-anaemic ID may lead to missed diagnoses and opportunities for treatment.

Background: Severe polytrauma is one of the leading causes of death and disability worldwide. Hyperferritinemia is increasingly recognized as a biomarker of critical illness, yet its prognostic significance in polytrauma remains underexplored. This multicenter study investigates the temporal dynamics of serum ferritin in polytrauma patients and its association with systemic inflammation, organ dysfunction, and mortality.

This study investigated the prevalence of Thalassemia (Thal) gene in pregnant women in the Quanzhou area, China. And explored the clinical application value of Erythroferrone (ERFE) and Hepcidin in screening pregnant women with Thal complicated by Iron-deficiency anemia (IDA, defined as serum ferritin (SF) < 20 μg/L). From January 2020 to December 2022, the detection rate of Thal in suspected Thal populations was 35.

Background: Thalassemias are inherited red blood cell disorders characterized by defective globin production, resulting in microcytic hypochromic anemia. Severe variants lead to transfusion dependence and consequent iron overload, often despite chelation therapy. The role of automated red blood cell exchange (RBCX) for transfusion-dependent thalassemia (TDT) is unclear and previously there was no specific apheresis parameters specific for thalassemia defined.

Objective: Ferritin is independently associated with oxidized Low-Density Lipoprotein (LDL). While high LDL levels are known independent risk factors for cardiovascular diseases, few studies have investigated the relationship between serum ferritin levels and long-term outcomes in CAD patients.
Methods: A prospective cohort study of CAD participants was performed in Xinjiang Medical University Affiliated First Hospital from December 2016 to October 2021.
