Identification of Three Families Carrying Hb Anti-Lepore Hong Kong Variant in Guangxi, China, and Analysis of Their Hematological Data.

Thalassemia is a single-gene genetic disease with a high incidence in southern China. To prevent and control thalassemia, the most commonly used procedure is hematology testing and hemoglobin (Hb) analysis, followed by thalassemia gene analysis in positive individuals. During routine testing for thalassemia, we identified three individuals with Hb A levels of >10.

Diagnostic Accuracy of Prenatal Fetal Ultrasound to Detect Cleft Palate in High-Risk Fetuses: A Systematic Review and Meta-Analysis.

Objectives: This systematic review and meta-analysis investigated the accuracy of prenatal fetal ultrasound (US) to detect cleft palate during the second and third trimester (12-36 weeks) of pregnancy in high-risk fetuses.

Methods: Pubmed and Embase databases were searched for studies that performed prenatal fetal US (comparator) and postnatal examination (reference standard) in fetuses at high risk for orofacial clefts. Risk of bias among included studies was assessed using the QUADAS-2.
