ABSTRACT
Objective: To compare the prognostic value of 3 diagnostic criteria of bronchopulmonary dysplasia (BPD) in preterm infants with gestational age<32 weeks. Methods: The retrospective cohort study was conducted to collect the clinical data of 285 preterm infants with BPD admitted to the Department of Neonatology, Children's Hospital Affiliated to Zhengzhou University from January 2019 to September 2021, who were followed up regularly after discharge. The primary composite adverse outcome was defined as death or severe respiratory morbidity from 36 weeks of corrected gestational age to 18 months of corrected age, and the secondary composite adverse outcome was defined as death or neurodevelopmental impairment. According to the primary or secondary composite adverse outcomes, the preterm infants were divided into the adverse prognosis group and the non-adverse prognosis group. The 2001 National Institute of Child Health and Human Development (NICHD) criteria, 2018 NICHD criteria, and 2019 Neonatal Research Network (NRN) criteria were used to diagnose and grade BPD in preterm infants. Chi-square test, Logistic regression analysis, receiver operating characteristic (ROC) curve and Delong test were used to analyze the prognostic value of the 3 diagnostic criteria. Results: The 285 preterm infants had a gestational age of 29.4 (28.1, 30.6) weeks and birth weight of 1 230 (1 000, 1 465) g, including 167 males (58.6%). Among 285 premature infants who completed follow-up, the primary composite adverse outcome occurred in 124 preterm infants (43.5%), and the secondary composite adverse outcome occurred in 40 preterm infants (14.0%). Multivariate Logistic regression analysis showed that severe BPD according to the 2001 NICHD criteria, gradeâ ¡and â ¢ BPD according to the 2018 NICHD criteria and grade 2 and 3 BPD according to the 2019 NRN criteria were all risk factors for primary composite adverse outcomes (all P<0.05). ROC curve showed that the area under the curve (AUC) of the 2018 NICHD criteria and 2019 NRN criteria were both higher than that of the 2001 NICHD criteria (0.70 and 0.70 vs. 0.61, Z=4.49 and 3.35, both P<0.001), but there was no significant difference between the 2018 NICHD and 2019 NRN criteria (Z=0.38, P=0.702). Multivariate Logistic regression analysis showed that the secondary composite adverse outcomes were all associated with grade â ¢ BPD according to the 2018 NICHD criteria and grade 3 BPD according to the 2019 NRN criteria (both P<0.05). ROC curve showed that the AUC of the 2018 NICHD criteria and 2019 NRN criteria were both higher than that of the 2001 NICHD criteria (0.71 and 0.71 vs. 0.58, Z=2.93 and 3.67, both P<0.001), but there was no statistically significant difference between the 2018 NICHD and 2019 NRN criteria (Z=0.02, P=0.984). Conclusion: The 2018 NICHD and 2019 NRN criteria demonstrate good and comparable predictive value for the primary and secondary composite adverse outcomes in preterm infants with BPD, surpassing the predictive efficacy of the 2001 NICHD criteria.

OBJECTIVE: This study aims to investigate the effect of oral care via the combined use of colostrum and sodium bicarbonate on the prevention of neonatal ventilator-associated pneumonia (VAP). PATIENTS AND METHODS: In accordance with the inclusion and exclusion criteria, 120 infant patients who were hospitalized in the neonatal intensive care unit (NICU) from January to October of 2019 were selected and randomly divided into three groups (40 cases in each group), namely, colostrum combined with sodium bicarbonate nursing (experimental group), colostrum (control group I), and sodium bicarbonate (control group II) groups. The primary outcomes measured included incidence rates of VAP and oral infection, positive rate of pathogenic bacteria after sputum culture, mechanical ventilation time, and length of stay (LOS). RESULTS: The incidence rates of VAP and oral infection and the positive rate of pathogenic bacteria after sputum culture of the experimental group, which were 6.67%, 10.00%, and 10.00%, respectively, were significantly different from those of control groups I and II (p < 0.05). The mechanical ventilation time of the experimental group was 156.07 ± 26.67 h, which was shortened by 9.79% and 9.43% compared with those of control groups I and II, respectively. The LOS of the experimental group was 17.6 ± 1.96 days, which was shortened by 17.74% and 17.50% compared with those of control groups I and II, respectively. The differences were statistically significant (p< 0.05). CONCLUSIONS: Oral care through the combined use of colostrum and sodium bicarbonate can lower the VAP incidence rate of infant patients and shorten their mechanical ventilation time and LOS.

OBJECTIVE: This study aims to discuss the effects of simulation training on improving the pre-examination, triage, prevention, and control of coronavirus disease 2019 (COVID-19), explain the psychological states of pre-examination and triage staff in general hospitals during the COVID-19 epidemic, and analyze relevant influencing factors. This study may serve as a reference of psychological consultation services to medical staff. SUBJECTS AND METHODS: This study included 60 nurses assigned in the pre-examination department, fever clinics, and isolation wards of a general hospital from January 26th to February 1st, 2020. Before assuming the posts, the nurses received simulation training on the clinical reception of suspected patients with COVID-19. Operation skills of the nurses before and after the training were assessed. RESULTS: The percent of passing significantly increased from 65% before the training to 98.33% after training (p<0.05). Training also significantly relieved the anxiety and depression of the nurses (p<0.05). CONCLUSIONS: Scenario-simulation training can increase the emergency abilities of pediatric nurses in the prevention and control of the COVID-19 epidemic and relieve the anxiety of nurses.
