Thalassemia is an inherited hematological disorder characterized by a decrease in the synthesis of or absence of one or more globin chains. Hepatitis E virus (HEV) is a major cause of acute viral hepatitis, constituting a major global health burden and emerging as a critical public health concern. HEV infection is mainly transmitted via the fecal-oral route; however, parenteral transmission through blood components has been reported in both developing and developed countries.

Introduction: Sickle cell disease (SCD) is the most common hemoglobinopathy in North America. The life expectancy of SCD has extended into adulthood with screenings, preventative care, and hydroxyurea. However, comorbidities arise as adults with SCD age, leading to early mortality.

Background: We sought to determine whether transamniotic stem cell therapy (TRASCET) could be a viable alternative for the fetal administration of genetically modified hematopoietic stem cells (HSCs) carrying a human hemoglobin subunit beta gene (hHBB) in a healthy syngeneic rat model.
Methods: Time-dated pregnant Lewis dams underwent volume-matched intra-amniotic injections in all their fetuses (n = 61) of a suspension of donor HSCs genetically modified with either both a hHBB gene and a firefly luciferase reporter gene (n = 42) or the firefly luciferase reporter gene alone to control for HBB-derived protein interspecies homology (n = 19) on gestational day 17 (E17; term = E21). Donor HSCs consisted of syngeneic cells phenotyped by flow cytometry with successful hHBB transduction confirmed by ELISA prior to administration in vivo.

Article Synopsis
- The study investigates the prevalence and genotypes of thalassemia in Lingui District, Guilin City, helping to inform prevention strategies.
- A retrospective analysis of 1,501 suspected cases revealed a 45.17% carrier rate, with 379 α-thalassemia and 270 β-thalassemia cases identified.
- The findings highlight the complexity of thalassemia genotypes in the region, underscoring the need for genetic counseling and prenatal testing efforts.

Objective: To analyze the application value of MCV, MCH and HbA in screening for thalassemia in the population of childbearing age in Quanzhou area, and to determine the optimal screening cut-off value of relevant indicators in this area.
Methods: 2 725 couples of childbearing age were included in the study and underwent routine blood test, capillary hemoglobin electrophoresis, and α and β thalassemia gene test. Statistical methods were used to analyze the distribution of thalassemia genotypes, and compare the performance of MCV, MCH, and HbA in screening various types of thalassemia.
