Study Design Goal: Evaluate the efficacy of UCM in 35-42 week neonates who are non-vigorous at birth compared to Early Cord Clamping (ECC). Specifically, level of H&H, outcomes of cardiac ultrasound or echo, and up to 2 years neonatal developmental outcomes. Participants: Obstetrics Gynecologists Contributions & Accomplishments Assisted with recruitment of 200+ term mothers, consenting of 50+ mothers, and the extraction of 1000+ patient data out of Cerner charts, our EHR system, into RedCap Performed 200+ open and close ended in person and phone surveys at 3, 9, 12, 18, and 24 month children enrolled in the study to evaluate their developmental outcomes https://static1.squarespace.com/static/606a4a049d38ba04fb739e9a/t/606ace2b1253c858d4ac9ea1/1617612341742/newborn-cord-cutting.jpeg Work - Sharp Mary Birch Hospital: Neonatal Research Institute - PREMOD - Premature Infants Receiving Milking or Delayed Cord Clamping Background Role: Research Associate Methods: Randomized Control Trial, prospective chart review, and close and open ended surveys Timeline: April 2017- Present (Estimated 5 years) Goals Client’s Goal: Should Physicians practice umbilical cord milking or delayed cord clamping in preterm neonates? Study Design Goal: This study is being done to find out whether umbilical cord milking (UCM) is at least as good as or better than delayed cord clamping (DCC) to reduce bleeding in the brain or prevent death in premature newborns. We will study short and long term outcomes of infants delivered before 32 weeks gestation that receive either UCM or DCC. Participants: Obstetrics Gynecologists Contributions & Accomplishments Assisted with recruitment of 200+ term mothers, consenting of 50+ mothers, and the extraction of 500+ patient data out of Cerner charts, our EHR system, into RedCap Performed 10+ open and close ended phone surveys in mandarin at 12, 18, and 24 month children enrolled in the study to evaluate their developmental outcomes https://static1.squarespace.com/static/606a4a049d38ba04fb739e9a/t/606ad2dc4da8764cfc69cfe5/1617613538306/bag-of-transfusion-blood-bank-transfusion-shut-.jpeg Work - Sharp Mary Birch Hospital: Neonatal Research Institute - Two-year neuro-developmental outcomes of preterm infants who received red blood cell transfusion Background Role: Research Associate Methods: Retrospective Cohort Chart Review Timeline: February 2020- January 2021 (11 months) Goals Client’s Goal: Should physicians decrease the amount of red blood cell transfusions in preterm infants? Study Design Goal: Our primary aim was to examine the relationship between receipt of RBC transfusion in preterm infants and their subsequent neurodevelopment at two years of age. We also conducted secondary analyses of: 1) cumulative number of transfusions 2) transfusions received in the first week of life 3) transfusions in a subcohort of extremely preterm infants with a gestational age <28 weeks. Participants: Obstetrics Gynecologists, Registered nurses Contributions & Accomplishments Assisted with research design and met with physicians, nurses, data scientists, and others to determine scope, purpose of the project Input 1000+ neonatal charts into RedCap database Used logistic and linear regression models, chi squared test, and other analytical models to identify associations between blood transfusion and neurodevelopmental outcomes in 654 study participants Impact Our research concluded that physicians should attempt to decrease the amount of red blood cell transfusions in preterm neonates. Our study demonstrates an association between RBC transfusion and lower cognitive and motor outcomes at two-years after adjustment for prematurity and illness at birth. Increasing number of transfusions was associated with an even greater severity of NDI. Prospective studies utilizing blood-saving strategies (placental transfusion or minimal blood draws) to avoid blood transfusion and improve long term outcomes are needed to confirm this association. https://static1.squarespace.com/static/606a4a049d38ba04fb739e9a/t/606ad060ff6586124031f9e6/1617613226529/35671740_154578837289432_r.jpeg Work - Sharp Mary Birch Hospital: Neonatal Research Institute - Association Between Umbilical Cord Management and 5 Minute Peripheral Oxygenation In Preterm Infants Background Role: Research Associate Methods: Retrospective Cohort Chart Review Timeline: October 2020 - January 2021 (4 months) Goals Client’s Goal: Should Physicians practice umbilical cord milking or delayed cord clamping in preterm infants? Study Design Goal: To compare 5 minute SpO2 and FiO2 levels between two different placental transfusion techniques in 23 to 31 weeks of gestation resuscitated premature infants in the delivery room. Participants: Obstetrics Gynecologists Contributions & Accomplishments Lead research design and met with physicians, nurses, data scientists, and others to determine scope, purpose of the project, and start a new delivery room database for the NRI Watched 30+ videos to collect quantitative data crucial for data analysis Used Python and Pycharm to combine 3 previous multi-centered data sets to total 328 preterm babies used in this study Impact Our research concluded that physicians should consider administering higher oxygenation (FiO2) during DCC due to low SpO2 levels and reserve prospective UCM techniques for more mature infants.
