However, EOS has a high mortality rate, and its clinical symptoms are variable and often atypical, posing significant challenges for early identification and treatment. This study aims to evaluate the performance of an EOS risk calculator in combination with inflammatory markers for predicting EOS in infants born to mothers with intrapartum fever while maintaining neonatal safety in China.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This was a retrospective cohort study involving 265 term neonates (gestational age: 37\u201341\u2076\/\u2087 weeks) born between the 1st of January 2024 and the 30th of June at the International Peace Maternity and Child Health Hospital. Eligible neonates were admitted to the neonatal intensive care unit (NICU) due to a intrapartum maternal fever (temperature &amp;gt;37.5\u2005\u00b0C). We collared and reviewed laboratory data and medical charts of all included neonates. EOS risk scores for all neonates were calculated using the EOS risk calculator, and the results were analyzed and compared with blood biomarkers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of the 265 neonates, 61 (23.0%) were diagnosed with EOS. Among the 204 (77.0%) low-risk newborns predicted by the EOS risk calculator, none developed culture-confirmed sepsis. Infected neonates exhibited significantly higher levels (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.01) of inflammatory markers, including C-reactive protein (CRP) and Interleukin 6 (IL-6), compared to uninfected counterparts. Receiver Operating Characteristic (ROC) Curve analysis revealed that when the EOS risk calculator was combined with inflammatory markers, CRP had the highest discriminative capacity [Area Under Curve (AUC): 0.84], while IL-6 exhibited moderate accuracy (AUC: 0.72). The combination of CRP and IL-6 further improved diagnostic performance (AUC: 0.85).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
