There is a relatively high incidence rate of invasive fungal infection (IFI) in preterm infants admitted to the neonatal intensive care unit (NICU), and early diagnosis of IFI is difficult in clinical practice. The patients developing IFI tend to have severe conditions, a long course of treatment, high hospital costs, high mortality, and poor prognosis, and therefore, the prevention of IFI is of particular importance. At present, fluconazole is often used as the first-line drug for the prevention of IFI in preterm infants, but no consensus has been reached on the specific dose and course of treatment, and there are still controversies over the targeted population and prophylactic effect. This article reviews the recent research on the pharmacological prevention strategies for IFI in preterm infants in the NICU, so as to provide a reference for clinicians.

OBJECTIVES: To investigate the risk factors for necrotizing enterocolitis (NEC) in preterm infants, and to establish a scoring model that can predict the development and guide the prevention of NEC. METHODS: A retrospective analysis was performed on the medical data of preterm infants who were admitted to the Department of Neonatology,Bethune First Hospital of Jilin University, from January 2011 to December 2020. These infants were divided into two groups: NEC (298 infants with Bell II stage or above) and non-NEC (300 infants). Univariate and multivariate analyses were performed to identify the factors influencing the development of NEC. A nomogram for predicting the risk of NEC was established based on the factors. The receiver operator characteristic (ROC) curve and the index of concordance (C-index) were used to evaluate the predictive performance of the nomogram. RESULTS: The multivariate logistic regression analysis showed that grade ≥2 intracranial hemorrhage, peripherally inserted central catheterization, breast milk fortifier, transfusion of red cell suspension, hematocrit >49.65%, mean corpuscular volume >114.35 fL, and mean platelet volume >10.95 fL were independent risk factors for NEC (P<0.05), while the use of pulmonary surfactant, the use of probiotics, and the platelet distribution width >11.8 fL were protective factors against NEC (P<0.05). The nomogram showed good accuracy in predicting the risk of NEC, with a bootstrap-corrected C-index of 0.844. The nomogram had an optimal cutoff value of 171.02 in predicting the presence or absence of NEC, with a sensitivity of 74.7% and a specificity of 80.5%. CONCLUSIONS The prediction nomogram for the risk of NEC has a certain clinical value in early prediction, targeted prevention, and early intervention of NEC.

OBJECTIVES: To systematically evaluate the effect of prophylactic use of hydrolyzed protein formula on gastrointestinal diseases and physical development in preterm infants. METHODS: A computerized search was performed in the databases including China National Knowledge Infrastructure, Wanfang Data, Weipu, PubMed, Embase, and the Cochrane Library to identify randomized controlled trials of the effect of prophylactic use of hydrolyzed protein formula on gastrointestinal diseases and physical growth in preterm infants. RevMan 5.3 software was used to perform a Meta analysis for the included studies. RESULTS: A total of 7 randomized controlled studies were included. The results of Meta analysis showed that compared with the whole protein formula, the prophylactic use of hydrolyzed protein formula could reduce the risk of neonatal necrotizing enterocolitis (RR=0.40, P=0.04) and feeding intolerance (RR=0.40, P=0.005), and had no significant effect on the growth of weight, length and head circumference (P>0.05). CONCLUSIONS Compared with the whole protein formula, the prophylactic use of hydrolyzed protein formula in preterm infants may reduce the occurrence of necrotizing enterocolitis and feeding intolerance, and can meet the nutrient requirement of physical development. However, the evidence is limited, and the results of this study cannot support the routine prophylactic use of hydrolyzed protein formula in preterm infants.

With the increase in the rescue success rate of critically ill preterm infants and extremely preterm infants, the incidence rate of bronchopulmonary dysplasia (BPD) is increasing year by year. BPD has a high mortality rate and high possibility of sequelae, which greatly affects the quality of life of preterm infants and brings a heavy burden to their families, and so the treatment of BPD is of vital importance. At present, no consensus has been reached on the treatment measures for BPD. However, recent studies have shown that early application of caffeine can prevent BPD. With reference to the latest studies on the effect of caffeine in the prevention of BPD, this article reviews the mechanism of action of caffeine in reducing pulmonary inflammation, improving morphological abnormalities of lung injury, reducing oxidative stress injury, and improving pulmonary function.

The gastrointestinal structure, function and immunity of preterm infants are immature. Furthermore the gastrointestinal microbe colonization is abnormal. Therefore the preterm infants are prone to a variety of gastrointestinal diseases. Probiotics can regulate gastrointestinal microbe constitute, improve gastrointestinal barrier function, reduce gastrointestinal inflammation response and regulate the immunity. At present, it is used for the prevention of necrotizing enterocolitis, late-onset sepsis, and feeding intolerance. The safety and efficacy of probiotics for preterm infants are still controversial.

OBJECTIVEThis study aimed to evaluate the effectiveness of multi-disciplinary treatment approaches in reducing neurological disabilities in premature infants.

METHODSA total of 117 infants who were born premature in our hospital between March 2008 and February 2010 but had no congenital malformations and no severe neonatal complications, were enrolled in this study. They were randomly allocated to a multi-disciplinary treatment group (n=63) and a control group (n=54). While patients in the control group underwent an early conventional treatment, those in the multi-disciplinary treatment group were subjected to regular development monitoring, neurological examination and screening for brain injury, neuro-nutrition and neurodevelopment therapies, and rehabilitation training.

RESULTSThe incidence rates of abnormalities in posture, reflex, sleep, muscle tone and EEG were significantly lower in the multi-disciplinary treatment group than in the control froup (P<0.05) at corrected postnatal ages of 6-12 months. At corrected postnatal ages of 6, 12, 18 and 24 months, both mental development index (MDI) and psychomotor development index (PDI) scores were significantly higher in the multi-disciplinary treatment group than in the control group (P<0.05). At corrected postnatal age of 3 years, incidence rates of cerebral palsy, language barrier, abnormal muscle tone and hearing impairment were significantly lower in the multi-disciplinary treatment group than in the control group (P<0.05).

CONCLUSIONSEarly multi-disciplinary intervention approaches may significantly improve mental and motor developments and reduce the incidence of cerebral palsy-associated neurological disabilities in premature infants.
