Summary: This study using the Th3/+ mouse model found that altered lipid metabolism and gut microbiota may be related to the development of cardiomyopathy in thalassemia. These findings are important for understanding the early biomarkers and therapeutic targets for the development of cardiomyopathy in thalassemia.

Summary: Using global proteomics, we found significant impairment in mitochondrial oxidative phosphorylation in the skeletal muscle of thalassemia mice, along with a shift in muscle fiber types and increased capillary density. These alterations led to metabolic dysfunction and reduced glucose handling capacity.

Summary: This article proposes a general framework for estimating iron overload in the liver using magnetic resonance imaging (MRI), considering various liver models. The iron overload estimation is formulated as a minimization problem with regularization functions assigned to unknown model parameters. An alternating direction method of multipliers (ADMM) is applied for parameter estimation. Three models were tested and compared using synthetic datasets, showing good correlation with ground truth T2* measurements. The proposed approaches were also evaluated using MRI scans of patients, demonstrating better performance than existing methods.

Summary: Iron homeostasis is regulated by hepcidin, which is influenced by factors such as iron stores, hypoxia, inflammation, and erythropoiesis. Beta-thalassemia patients exhibit iron deficiency, iron overload, and ineffective erythropoiesis. Recent research has identified new diagnostic markers and therapeutic targets for beta-thalassemia.

Summary: This study compared two methods for preparing optimal P-RBCs products for beta-thalassemia major patients, finding that method 1 resulted in higher RBC count and Hb content, while method 2 produced P-RBCs with lower levels of K+, iron, and storage lesions markers. Further clinical studies are needed to determine the impact of these differences on transfusion-related complications and the quality of life of beta TM patients.

Summary: Management of beta-thalassemia in the West Bank presents challenges due to the lack of available therapies, leading to recurrent transfusions. Characteristics of patients include anemia, iron overload, and abnormal liver function tests. Iron chelation medication choice is associated with serum ferritin levels, highlighting the need for personalized assessment and follow-up protocols.

Summary: This study suggests that vascular complications in patients with beta-thalassemia are associated with oxidative modification of lipoproteins. The modification of lipid components may alter lipid peroxidation rate and products. Core lipids and cholesteryl esters levels determine the rate and total production of L center dot. Overall, lipoproteins in beta-thalassemia patients are more susceptible to lipid peroxidation.

Summary: The study identifies an association between three iron-related miRNAs and tissue iron overload in transfusion-dependent beta-thalassemia major patients. Results suggest that circulating miR-let-7d and miR-200b are downregulated, while miR-122 is upregulated in TDT patients. Aberrant expression of miRNAs is significantly associated with increased iron accumulation in hepatic and cardiac tissues, making them potential predictive biomarkers for tissue iron excess.

Summary: Combination chelation therapy is a viable option for transfusion-dependent thalassemia patients who have not achieved iron balance with monotherapy or need intensified treatment for rapid iron reduction. It allows for a more personalized approach, improving tolerability, adherence, and quality of life. Real-life data highlights the importance of compliance in achieving meaningful reduction in iron overload compared to monotherapy.

Summary: The study demonstrates that curcuminoids have significant therapeutic effects on non-transfused beta-thalassemia/Hb E patients, including reducing oxidative stress, hypercoagulability, and inflammation markers levels, especially in the 1000 mg/day dosage group. Furthermore, the baseline ferritin levels also impact the efficacy of curcuminoids supplementation.

Summary: Renal iron accumulation is not common in sickle/beta-thalassemia patients, with a significantly lower frequency compared to homozygous SCD patients. Kidney T2* values are similar between sickle/beta-thalassemia and TM patients, but significantly lower in regularly transfused homozygous SCD patients. Age, gender, splenectomy, and transfusion or chelation therapy are not associated with global renal T2* values, but there is a significant inverse correlation with serum lactate dehydrogenase and indirect bilirubin.

Summary: This study investigated the changes in gut microbiota and metabolites in iron-overload thalassemia, as well as the effect of an iron chelator on gut dysbiosis and inflammation. The results showed that iron-overload led to gut dysbiosis, inflammation, and disturbance of metabolites, and treatment with the iron chelator deferiprone alleviated these conditions more effectively in wild-type mice than in thalassemic mice. The study suggests that deferiprone may be a potential therapeutic drug for iron-related gut diseases.

Summary: According to a systematic review of human clinical literature, antenatal corticosteroids (ACS) exposure does not have long-term effects on cardiovascular function in human offspring. However, due to the limited number, heterogeneity, and mixed quality of studies, the effects on cardiac structure and other measures of cardiac function remain unclear. Further research is needed to assess central cardiac function in human offspring exposed to ACS.

Summary: Challenges in haematopoietic stem cell transplantation, such as low bone marrow engraftment, graft versus host disease, and the need for long-term immunosuppression, could be addressed using tissue-resident T regulatory cells (Tregs), specifically bone marrow Tregs. Controlling adverse immune response and reducing risks associated with long-term immunosuppression is crucial in clinical practice. Tregs have shown promise as a safe and effective therapy, and their potential in haematopoietic stem cell transplantation is being explored.

Summary: Fetoscopic video mosaicking can create an expanded field-of-view image of the fetoscopic intraoperative environment to support surgeons during twin-to-twin transfusion syndrome treatment. However, existing methods relying on vessel presence have limitations. We propose a vessel-guided hybrid fetoscopic mosaicking framework that combines placental vessel-based registration and deep learning-based dense matching to improve overall performance. Experimental results demonstrate the robustness of the proposed framework over state-of-the-art methods, even in vessel-free and low-textured fetoscopic views.

Summary: Placental examination is of great importance as it provides valuable clinical information related to fetal development, neonatal morbidity and mortality, and future health outcomes. The examination can identify intrinsic or secondary placental lesions that are directly associated with adverse neonatal outcomes or indicate an unfavorable intrauterine environment. This article describes the clinical value of placental examination, common pathological findings, how to interpret key findings, as well as the medico-legal and financial implications and current and future clinical considerations.

Summary: Fetal gene therapy was proposed in the late 1990s when gene therapy was at its peak of inflated expectations. Over the years, gene therapy matured and became a clinical and market reality. The trajectory of treatment for genetic diseases is now focused on earlier intervention, with increasing ability to diagnose genetic diseases in utero. Recent clinical trials have pointed towards the potential for fetal gene therapy. This review summarizes the history of fetal gene therapy, advancements in fetal surgery and diagnosis, and the scope of preclinical gene therapy for inherited metabolic diseases.

Summary: This study analyzes the trends in feticide in singleton pregnancy in England and Wales between 2012 and 2020. The prevalence of feticide fluctuated, but there was an overall decrease over the years. Intracardiac injection of potassium chloride was the most common method used for feticide. Most feticides took place at 23 weeks, followed by 22 weeks and between 20 and 21 weeks.
