Overview

Keiya Ozawa is affiliated with Jichi Medical University in Japan and specializes in the field of medicine, with a focused expertise in pediatrics, perinatology, child health, surgery, obstetrics and gynecology, pulmonary and respiratory medicine, and molecular biology. Their research work predominantly addresses topics related to assisted reproductive technology and twin pregnancy, pregnancy and preeclampsia studies, prenatal screening and diagnostics, congenital diaphragmatic hernia studies, neonatal respiratory health, birth, development, health, and tracheal and airway disorders.

Their recent publications reflect a consistent involvement in perinatal and prenatal diagnostics research, including studies on twin-to-twin transfusion syndrome and neurodevelopmental outcomes following fetal surgeries. Key recent papers include:

  • "Omalizumab concentrations in pregnancy and lactation: A case study" (2020) published in The Journal of Allergy and Clinical Immunology In Practice
  • "Risk Profiling of the Solomon Technique versus Selective Technique of Fetoscopic Laser Surgery for Twin-Twin Transfusion Syndrome" (2021) published in Twin Research and Human Genetics
  • "Molecular Mechanisms Underlying Twin-to-Twin Transfusion Syndrome" (2022) published in Cells
  • "Neurodevelopmental impairment at 3 years of age after fetoscopic laser surgery for twin-to-twin transfusion syndrome" (2020) published in Prenatal Diagnosis
  • "Long-term neurodevelopmental outcomes of the pump twin in twin reversed arterial perfusion sequence treated by radiofrequency ablation" (2021) also published in Prenatal Diagnosis

Ozawa collaborates frequently with several coauthors, notably including Seiji Wada, Haruhiko Sago, Jin Muromoto, Rika Sugibayashi, and Yushi Ito. These ongoing collaborations underline a network of researchers focused on prenatal health and fetal medicine.

Their research is regularly published in journals such as the Journal of Obstetrics and Gynaecology Research, Ultrasound in Obstetrics and Gynecology, Prenatal Diagnosis, Journal of Medical Ultrasonics, and Twin Research and Human Genetics. These venues are well-regarded within medical and perinatal research communities and reflect the primary dissemination outlets for Ozawa's work.
