Comprehensive data regarding the epidemiology and prevalence of thalassemia in mainland China are lacking. To assess the prevalence of thalassemia, we performed a meta-analysis including 16 articles published from 1981 to 2015. The overall prevalence of α-thalassemia, β-thalassemia and α + β-thalassemia was 7.88%, 2.21% and 0.48%, respectively. Trends in thalassemia prevalence in mainland China were not steady; a prevalence map based on a geographic information system (GIS) showed that the geographic distribution of thalassemia was highest in the south of China and decreased from south to north. Additionally, the most common α- and β-globin gene mutation was -- and CD41/42, respectively. The current study provides valuable information regarding epidemiology and intervention and supports the planning, implementation and management of prevention programmes for public health.

Objectives: To determine the prevalence of family planning practice among the parents of children affected with beta thalassemia major (BTM) and to determine the relationship between various factors and family planning practice in Makran division Balochistan.
Methods: A cross-sectional observational study was conducted on 190 parents having BTM children registered in thalassemia care centers throughout the Makran division from May 2023 to October 2023. The structured questionnaire was used and data was collected using the non-probability convenience technique.
Non-Invasive Determination of the Paternal Inheritance in Pregnancies at Risk for β-Thalassaemia by Analyzing Cell-Free Fetal DNA Using Targeted Next-Generation Sequencing.

Non-invasive prenatal testing (NIPT) has been widely adopted for the screening of chromosomal abnormalities; however, its adoption for monogenic disorders, such as β-thalassaemia, has proven challenging. Haemoglobinopathies are the most common monogenic disorders globally, with β-thalassaemia being particularly prevalent in Cyprus. This study introduces a non-invasive prenatal haplotyping (NIPH) assay for β-thalassaemia, utilizing cell-free DNA (cfDNA) from maternal plasma.

Background: This study aimed to describe Sickle Cell Disease (SCD) phenotypes, sociodemographic characteristics, healthcare, and clinical outcomes of patients with SCD attending Mnazi Mmoja Hospital (MMH) in Zanzibar.
Methods: Individuals who visited MMH between September 2021 and December 2022 and were known or suspected to have SCD were enrolled in the clinic. Sociodemographic characteristics and clinical features were documented, and laboratory tests were performed.
Barriers to Blood Donation: Donor Deferrals in a Saudi Hospital Setting.

Department of Clinical Laboratory Sciences, College of Applied Medical Sciences-Al-Qurayyat, Jouf University, Saudi Arabia.
Objective: Blood donation plays a critical role in healthcare systems by supplying blood and blood products for surgeries, emergency care, and chronic disease management. In Saudi Arabia, the prevalence of genetic disorders, like sickle cell disease and thalassemia, further increase the need for a stable blood supply. However, high rates of donor deferrals remain a significant barrier to maintaining a reliable blood supply.

Thalassemia is an inherited blood disorder and traditionally considered more prevalent in Southern China. However, with increased migration and intermarriage, more and more thalassemia carriers had been reported in Northern China. The lack of screening for thalassemia carriers may also result in missed diagnosis in Northern China.
