The contribution of low Apgar scores in identifying neonates with short-term morbidities in a large single center cohort.

Objective: To evaluate the association and utility of low 1- and 5-min Apgar scores to identify short-term morbidities in a large newborn cohort.

Methods: 15,542 infants >22 weeks gestation from a single center were included. Clinical data and low Apgar scores were analyzed for significance to ten short-term outcomes and were used to construct Receiver Operating Characteristic Curves and the AUC calculated for ten outcomes.

Resonance Raman Spectroscopy Tissue Oxygenation Measurements in Neonates.

Introduction: Current oxygen monitoring by pulse oximetry has limitations and cannot provide estimates of the oxygen content in the microvasculature, where oxygen is used. Resonance Raman spectroscopy (RRS) provides noninvasive microvascular oxygen measurement. The objectives of this study were to (i) measure the correlation between preductal RRS microvascular oxygen saturations (RRS-StO2) and central venous oxygen saturation (SCVO2), (ii) develop normative data for RRS-StO2 measurements in healthy preterm infants, and (iii) determine the effect of blood transfusion on RRS-StO2.

The Apgar score in clinical research: for what, how and by whom it is used.

Objectives: To review how the Apgar score is used in published clinical research as well as who uses it, and how this may have changed between 1989-90 and 2018-19.

Methods: Pubmed search for English publications using MeSH Terms "apgar score" OR "apgar" AND "score" AND "humans" for epochs 1989-90 & 2018-19. The location and specialty of first author, primary purpose and how the Apgar score was used was recorded.
