Objective To explore the effect of histologic chorioamnionitis(HCA)on clinical outcomes of preterm infants with a gestational age<34 weeks.Methods This retrospective study enrolled 497 cases of premature infants with a gestational age<34 weeks and their mothers who were hospitalized in the Qingdao Women and Children's Hospital from January 2019 to December 2022.According to whether the pathology of placenta was diagnosed as HCA or not,patients were divided into the HCA group(257 cases)and the control group(240 cases).The propensity score matching analysis was performed at a ratio of 1︰1.Ten items were matched,including gestational age,birth weight,gender,cesarean section,gestational diabetes mellitus,gestational hypertension,placental abruption,premature rupture of membranes,use of antenatal glucocorticoids and assisted reproductive technology.The differences of major complications and survival rate were compared between the two groups.Results A total of 156 pairs premature infants were successfully matched.Before matching,the incidences of early-onset sepsis(EOS)and bronchopulmonary dysplasia(BPD)were higher in the HCA group than those of the control group(26.1%vs.7.5%,45.1%vs.25.8%,P<0.01).The incidence of EOS was higher in the HCA group than that of the control group after matching(24.4%vs.7.7%,P<0.01),and the incidence of neonatal respiratory distress syndrome(NRDS)was significantly lower in the HCA group than that in the control group after matching(34.0%vs.46.8%,P<0.05).There were no significant differences in survival rate and the incidences of other complications between the two groups before and after matching(P>0.05).Conclusion Preterm infants exposed to HCA have a higher risk of EOS and a lower risk of NRDS after propensity score matching.HCA has no significant effect on survival rate and other complications of premature infants.

Objective:To investigate the perinatal risk factors and correlation between bronchopulmonary dysplasia (BPD) and retinopathy of prematurity (ROP).Methods:A retrospective analysis was performed on 173 preterm infants born at less than 32 weeks' gestation with BPD who were admitted to the neonatal intensive care unit (NICU) of the Women and Children's Hospital of Qingdao University from June 2017 to July 2022. According to the diagnostic criteria for ROP, these preterm infants were divided into the ROP group ( n=64) and the non-ROP group ( n=109). Chi-square test, two independent samples t-test, and Mann-Whitney U test were used to compare the general data, treatment, and the incidence of complications between the two groups. Multivariate logistic stepwise regression analysis was used to analyze the independent risk factors of ROP in preterm infants with BPD and the receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of independent risk factors on ROP. The correlation between the severity of BPD and the incidence of ROP was analyzed. Results:The gestational age at birth [(28.0±1.1) vs. (28.8±1.2) weeks, t=4.01], the birth weight [(1 075.9±141.4) vs. (1 143.2±168.6) g, t=2.68], the partial pressure of carbon dioxide [42.5 mmHg (1 mmHg=0.133 kPa) (34.0-51.0 mmHg) vs. 47.0 mmHg (39.0-54.0 mmHg), Z=-2.31], and the total fluid intake on the first day of birth [80.0 ml (72.3-88.7 ml) vs. 83.6 ml (76.6-92.8 ml), Z=-2.28] in the ROP group were all lower than those in the non-ROP group (all P<0.05). While the prothrombin time [15.7 s (14.1-17.7 s) vs. 14.6 s (13.1-16.7 s), Z=-2.17], activated partial thromboplastin time [64.7 s (52.9-77.9 s) vs. 55.8 s (48.4-68.9 s), Z=-2.12], the proportion of patients treated with pulmonary surfactant [71.9% (46/64) vs. 49.5% (54/109), χ 2=8.25], the total duration of oxygen supplementation [50.5 d (40.0-64.0 d) vs. 45.0 d (37.0-52.0 d), Z=-2.77], the duration of invasive ventilation [5.0 d (1.0-11.0 d) vs. 1.0 d (0.0-5.0 d), Z=-4.03], the duration of noninvasive ventilation or high-flow oxygen therapy [(31.7±12.7) vs. (26.4±13.1) d, t=-2.59], and the incidence of neonatal respiratory distress syndrome [76.6% (49/64) vs. 57.8% (63/109), χ 2=6.22] were increased in the ROP group (all P<0.05). There was no significant difference in the proportion of BPD treated with corticosteroids between the ROP and non-ROP groups [60.3% (38/63) vs. 74.3% (81/109), χ 2=3.67, P=0.055]. Multivariate logistic stepwise regression analysis showed that smaller gestational age ( OR=1.599, 95% CI: 1.126-2.272, P=0.009), less fluid intake on the first day ( OR=1.033, 95% CI: 1.004-1.062, P=0.024), and longer duration of invasive ventilation ( OR=1.076, 95% CI:1.017-1.138, P=0.011) were independent risk factors for ROP in BPD infants, while glucocorticoid treatment was an independent protective factor ( OR=0.378, 95% CI:0.173-0.827, P=0.015). Most patients with mild or moderate BPD did not develop ROP [64.6% (73/113) and 66.7% (34/51)], while those with severe BPD were more likely to be complicated by ROP (7/9) ( χ 2=6.84, P=0.033). Conclusions:BPD infants with smaller gestational age, longer duration of invasive ventilation, and less fluid intake on the first day of birth are more likely to develop ROP, while glucocorticoid therapy can reduce the incidence of ROP in this population. Severe BPD may increase the risk of ROP in infants.

Objective:To analyze the risk factors of pulmonary hemorrhage in very low and extremely low birth weight, and to provide reference for the treatment of pulmonary hemorrhage.Methods:The clinical data of very low and extremely low birth weight infants hospitalized in Qingdao Women and Children′s Hospital NICU from January 2017 to December 2021 were retrospectively analyzed.Eighty-six infants who were diagnosed with pulmonary hemorrhage were selected as the pulmonary hemorrhage group, and two hundred and two infants without pulmonary hemorrhage were selected as the control group.The differences of the survival rates, complications and parameters of platelet between the two groups were compared, and the risk factors of pulmonary hemorrhage by multivariate Logistic regression were analyzed.Results:The survival rate of pulmonary hemorrhage group and control group were 65.1%(56/86) and 90.1%(182/202), respectively.The survival rate of control group was significantly higher than that in the pulmonary hemorrhage group( χ2=26.241, P<0.01). There was no significant difference in fluid intake between the two groups within three days after birth( t=0.936, 1.811, 1.840, P=0.350, 0.073, 0.069). The multivariate Logistic regression analysis showed hemodynamically significant patent ductus arteriosus( OR=2.304, 95% CI: 0.213~1.564, P=0.010), disseminated intravascular coagulation( OR=3.143, 95% CI: 0.061~2.521, P=0.028), thrombocytopenia( OR=0.991, 95% CI: -0.015~-0.005, P=0.001) and low mean platelet volume( OR=0.337, 95% CI: -1.657~-0.739, P=0.001) were the risk factors of pulmonary hemorrhage. Conclusion:Hemodynamically significant patent ductus arteriosus, disseminated intravascular coagulation, thrombocytopenia and low mean platelet volume were associated with increased risks for pulmonary hemorrhage in very low and extremely low birth weight.These risk factors should be actively monitored and treated, which is helpful to early identify and prevent pulmonary hemorrhage.

Objective:To evaluate the predictive values of the Status Epilepticus in Pediatric Patients Severity Score (STEPSS) and END-IT score in the short-term prognosis of children with status epilepticus (SE).Methods:It was a retrospective study involving 103 children with SE who were admitted to the Qingdao Women and Children′s Hospital Affiliated to Qingdao University from January 1, 2012 to January 1, 2022.Glasgow Outcome Scale was used to evaluate the prognosis at discharge, and the children were divided into good prognosis group ( n=78) and poor prognosis group ( n=25). Risk factors for poor prognosis of SE in children were analyzed by Logistic regression.Receiver operating characteristic (ROC) curve was used to evaluate the prognostic values of STEPSS and END-IT score in children with SE. Results:Compared with those of the good prognosis group, significantly younger age [16 (9, 58) months vs.56 (21, 84) months, Z=-3.068, P=0.002], higher blood lactic acid levels [3.16 (2.43, 4.01) mmol/L vs.1.67 (1.32, 2.10) mmol/L, Z=-6.085, P<0.001], STEPSS scores [3.0(3.0, 4.0) points vs.1.0(1.0, 2.0) points, Z=-6.956, P<0.001], END-IT scores [3.0(1.5, 4.0) points vs.1.0(0, 1.0) points, Z=-5.502, P<0.001], proportion of developmental delay ( χ2=16.756, P<0.001), abnormal brain magnetic resonance imagine examination ( χ2=5.860, P=0.015), use of ventilator and multiple drugs (all P<0.001), and longer duration of anti-SE therapy time( Z=1.488, P=0.024) were detected in the poor prognosis group. Logistic regression analysis indicated that increased blood lactic acid ( OR=7.975, 95% CI: 2.705-23.518), increased drug types ( OR=14.562, 95% CI: 2.035-104.173), STEPSS scores( OR=8.914, 95% CI: 2.824-28.140) and END-IT scores ( OR=2.209, 95% CI: 1.046-4.667) were risk factors for the poor prognosis of SE in children.The area under the curve (AUC) of STEPSS in predicting the poor prognosis of SE in children was 0.939, with the cut-off value, sensitivity, specificity and Youden index of 2.5 points, 96.0%, 85.9% and 0.82, respectively.AUC of END-IT scores in predicting the poor prognosis of SE in children was 0.853, with the cut-off value, sensitivity, specificity and Youden index of 1.5 points, 76.0%, 75.6% and 0.52, respectively.AUC of STEPSS in predicting the poor prognosis of SE in children was significantly higher than that of END-IT scores ( U=36.91, P<0.05). The predictive value of STEPSS combined with END-IT was higher, and the sensitivity and negative predictive value of parallel test were 100.0%, while the specificity and positive predictive value of series test were 94.9% and 81.8%, respectively. Conclusions:STEPSS and END-IT scores may be used as predictors for the poor prognosis of SE in children.Their combination provides a better prediction.

Objective:To investigate the prognosis value of the Child-Turcotte-Pugh (CTP), pediatrics end-stage liver disease/model for end-stage liver disease(PELD/MELD) and sequential organ failure assessment (SOFA) scores in pediatric acute liver failure (PALF) at 28 th day. Methods:Fifty-four PALF patients admitted in the Pediatric Intensive Care Unit (PICU) and Infection Department of Pediatrics, Qingdao Women′s and Children′s Hospital from June 1, 2012 to June 1, 2019 were included in the study.According to the survival of PALF patients on the 28 th day, they were divided into the survival group (28 cases) and the death group (26 cases). Baseline characte-ristics and laboratory examination data of PALF patients in both groups were collected and compared.Receiver operating characteristic (ROC) curve was used to evaluate the prognostic value of CTP, PELD/MELD and SOFA scores in PALF. Results:The mortality rate of 54 PALF patients was 48.1%.Compared with the survival group, PALF patients in the death group were significantly younger than those in survival group [11.0(3.8-39.0) months vs.14.5(7.3-84.0) months]( Z=-2.145, P=0.020). In addition, CTP, PELD/MELD and SOFA scores were significantly higher in the death group than those in survival group [14.0(11.7-15.0) vs.9.0(7.0-10.0), 32.0(29.0-36.0) vs.25.0(22.0-26.0), 13.0(11.0-16.0) vs.6.0(4.0-7.0)]( Z=-5.095, -4.894, -5.502, all P<0.05). Serum lactate level, blood ammonia level, total bilirubin, direct bilirubin and international normalized ratio were significantly higher in the death group than those in survival group [3.4(2.1-5.3) mmol/L vs.1.5(0.8-2.3) mmol/L, 69.5(46.9-102.9) μmol/L vs.41.7(27.3-50.3) μmol/L, 173.0(97.0-237.2) μmol/L vs.71.9(62.0-136.9) μmol/L, 132.3(53.6-206.2)μmol/L vs.59.3(62.0-99.7) μmol/L, 2.6(1.8-3.5) vs.1.7(1.5-1.9)]( Z=-4.027, -3.220, -2.649, -2.648, -3.807, all P<0.05). Prothrombin time (PT) was significantly prolonged in the death group than that of survival group [27.5(19.2-41.9)s vs.17.8(16.9-22.2)s]( Z=-3.489, P<0.05). Compared with those of survival group, serum albumin, alanine transaminase (ALT) and alpha fetoprotein (AFP) levels were significantly lower in the death group [(30.9±1.0) g/L vs.(33.6±0.9) g/L, 379.2(163.3-880.3) U/L vs.962.5(457.0-1 657.3) U/L, 7.5(0.7-115.8) μg/L vs.22.1(7.9-91.3) μg/L]( t=2.049, Z=-2.510, -2.342, respectively, all P<0.05). The incidence of alimentary tract hemorrhage was significantly higher in the death group than that of survival group (22/26 cases vs.11/28 cases)( χ2=13.340, P<0.05). The cut-off value of CTP, PELD/MELD and SOFA scores in predicting the prognosis of PALF were 11.5, 28.5 and 10.0, respectively.Among the three scoring systems, the specificity and positive predictive value of SOFA scores remained the highest.The sensitivity and specific of a combination of three scoring systems in predicting the prognosis of PALF were 92.3% and 89.3%, respectively, and its Youden index was the highest than that of a single scoring of either CTP, PELD/MELD or SOFA ( Z=2.19, P<0.05). Conclusions:CTP, PELD/MELD and SOFA scores have high predictive value for the short-term prognosis of PALF.The combined detection of the three scoring systems can improve the forecasting efficiency of PALD.
