AI Article Synopsis

  • The study aimed to determine normal reference values for fetal middle cerebral artery peak systolic velocity (MCA PSV) between 20 to 37 weeks of gestation at Srinagarind Hospital.
  • A descriptive cross-sectional study was conducted using gray scale ultrasonography and Doppler imaging on normal fetuses at various gestational ages.
  • The findings indicated an increase in MCA PSV from 24.34 cm/sec at 20 weeks to 59.04 cm/sec at 37 weeks, leading to the creation of a normogram for fetal MCA PSV for this gestational period.

Article Abstract

Objective: To establish normal references of fetal middle cerebral artery peak systolic velocity (MCA PSV) at 20 to 37 weeks of gestation at Srinagarind Hospital.

Material And Method: A descriptive cross-sectional study was performed Normal fetuses at 20 to 37 weeks of gestation were studied by gray scale ultrasonography initially and then Doppler of MCA PSV.

Results: At least 18 pregnant women of each gestational age with an uncomplicated singleton were enrolled The MCA PSV was increased as gestational age advanced from 24.34 cm/sec (SD 3.91) at 20 weeks to 59.04 cm/sec (SD 10.80) at 37 weeks.

Conclusion: A normogram of fetal MCA PSV at 20 to 37 weeks of gestation at Srinagarind hospital was generated.

Objective: Cesarean sections (CS) are among the most performed surgical procedures in the world. Small variations in surgical techniques could have a significant impact on a global scale, for example, in postoperative complications. In the present study we aimed to observe and audit every single step used during first time CS.

Purpose: Human brain development during gestation is complex, as both structure and function are rapidly forming. Structural imaging methods using MRI are well developed to explore these changes, but functional imaging tools are lacking. Low-field MRI is a promising modality to bridge this gap.

Introduction Respiratory distress syndrome (RDS) is a leading cause of morbidity and mortality among preterm infants, necessitating effective treatment strategies. This study compared the efficacy of Beractant (SURVANTA®) to Poractant alfa (CUROSURF®) in treating RDS in preterm infants admitted to Tawam Hospital in the UAE. Methodology This retrospective study included preterm infants from 23+0 to 36+6 weeks of gestation with a diagnosis of RDS and treatment by Beractant or Poractant alfa within 48 hours of life between January 2020 and March 2023.

Thrombotic thrombocytopenic purpura (TTP) is an exceptionally rare complication during pregnancy and even rarer when it coincides with severe preeclampsia in the same index pregnancy. We report the case of a 36-year-old female who presented with confusion at 38 weeks of gestation. Although her signs and symptoms strongly suggested severe preeclampsia, she was expected to make a full recovery after an emergency C-section.
