Abstract Background Neonatal hypothermia, defined as a temperature < 36.5°C, is a major contributor to neonatal mortality and morbidity. Hypothermia in preterm infants remains a challenge in the neonatal intensive care unit (NICU) for many reasons.Objective To investigate the incidence of admission hypothermia (AH) in very low-birth weight (VLBW) infants in multiple NICUs in Shandong Province, China, and to provide clinical evidence for the implementation of quality improvement practices to reduce the incidence of AH in NICU.Methods This retrospective, observational study was carried out over a period of 12 months, from January 1, 2018 to December 31, 2018. The correlations between hypothermia preventive measures and the incidence of AH were analysed by descriptive statistical methods and a Spearman analysis. The associations between AH and maternal and neonatal variables were tested with bivariate analyses, followed by stepwise logistic regression. P <0.05 was considered statistically significant.Results A total of 1639 in-born infants who were born at a weight less than 1500 g were enrolled in the study on their day of birth. Among them, 1295 VLBW infants fulfilled the inclusion criteria. The incidence of AH was 87.9% in VLBW infants among the 28 NICUs. We investigated whether team training and education, such as monthly chart reporting on hypothermia in preterm infants on admission to the NICU, which was associated with 10.7% of all the cases, could decrease the rate of AH. Indeed, transport with a heated transport incubator was associated with 9.3% of the cases. here was a negative correlation between the incidence of AH and the number of quality improvement measures implemented to prevent hypothermia (r= -0.242, p <0.05). A low birth weight, intubation in the delivery room , and a low 5-min Apgar score were significantly associated with AH. Conclusion: The incidence of AH was high. There was a negative correlation between the incidence of AH and the number of quality improvement measures implemented to prevent hypothermia. It is important to monitor for AH in newborns who have a low birth weight, who have a low Apgar score at 5 min and who require intubation in the delivery room.

ABSTRACT Objective: To assess the prevalence of hypothermia in the delivery room, at admission, and 2 to 3 hours after admission in the neonatal intensive care unit (NICU), factors associated and possible relationship with morbidity and mortality in preterm infants with very low birth weight (VLBW). Methods: Cross-sectional study with data collection based on a retrospective review of medical records and including infants born in 2016 and 2017, with birth weights <1500g, and gestational ages <34 weeks. Data about VLBW preterm infants, maternal data and temperature in the delivery room were analyzed. Hypothermia was considered when axillary temperature <36°C. For statistical analysis, the chi-square test or G test, canonical and Spearman correlation, and logistic regression were used. Results: 149 newborns (NB) were included in the study. The prevalence of hypothermia in delivery room, at admission to the NICU and 2 to 3 hours after admission was 25.8%, 41.5% and 40.2%, respectively. The temperature of NBs was directly proportional to gestational age (p<0.010), birth weight (p<0.010), and Apgar score (p<0.050). There was an inverse association with hypothermia in the delivery room and cesarean delivery (OR 0.25; p=0.016). Conclusions: Hypothermia was a prevalent problem in the studied population. The neonatal temperature was directly proportional to gestational age, birth weight and Apgar score. Hypothermia was associated with maternal factors, such as cesarean delivery. It is necessary to implement and improve strategies for its prevention.

Abstract Background: Hypothermia is still a common problem and is associated with increased mortality and morbidity in preterm infants, especially in China. The objective of this study was to evaluate the efficacy of a targeted quality improvement (QI) project of hypothermia preventive measures in very low-birth weight (VLBW) infants in 3 tertiary neonatal intensive care unit (NICU) in China.Methods: Based on the literature, our preliminary findings and the needs of each unit, our team decided to focus efforts on equipment (transport incubator, pre-warmed hats and polyethylene wrap), team training and education, as well as temperature documentation and workflow. The primary outcome measure was the incidence of hypothermia, defined as temperature (rectal temperature) below 36.5ºC on admission to the NICU. This quality improvement (QI) initiative used the rapid cycle Plan - Do - Study - Act (PDSA) approach. The outcomes of pre–quality improvement (pre-QI) group (January 1, 2018– December 31, 2018) were compared with post-QI group (January 1, 2019–December 31, 2019). The study enrolled preterm infants born at less than 32 weeks’ gestation with very low birth weight less than 1500 g born at 3 academic, tertiary-care hospitals including Shandong Provincial Hospital, The First Affiliated Hospital of Shandong First Medical University, LiaoCheng People’s Hospital Affiliated to Shandong First Medical University between January 2018 and December 2019.Results: A total of 636 VLBW infants were included in this analysis, of which 235 infants (36.9%) were included in the pre-QI group and 295 infants (46.4%) in the post-QI group. The incidence of hypothermia decreased significantly from 92.3% to 62% (P < 0.001), and the mean body temperature on admission to NICU increased significantly from 35.5˚C to 36˚C (P < 0.001). There were one cases (0.3%) of neonatal hyperthermia. Infants in the post-QI group had lower rates of mortality (16.1% vs 8.8%, P = 0.01). Conclusions: Targeted interventions can dramatically reduce admission hypothermia and improve the outcome of VLBW infants in China.

Abstract Background and aim Human milk has potential protective effects against bronchopulmonary dysplasia (BPD). However, studies on the association between the dose of human milk and BPD in China are limited. This study aimed to evaluate the dose-dependent effects of human milk on BPD and other neonatal morbidities in very low birth weight (VLBW) infants. Methods This retrospective cohort study of preterm infants was conducted on preterm infants of gestational age ≤ 34 weeks and birth weight < 1500 g admitted to the multicenter clinical research database for breastfeeding quality improvement in Jiangsu province. The multivariate analysis was performed to compare the effect outcomes of daily graded doses [1–24 mL/(kg · day), 25–49 mL/(kg · day), and ≥ 50 mL/(kg · day) of body weight] of human milk on neonatal outcomes throughout the first 4 weeks of life versus a reference group receiving no human milk. The models were adjusted for potential confounding variables. Results Of 964 included infants, 279 (28.9%) received exclusive preterm formula, 128 (13.3%) received 1–24 ml/(kg · day), 139 (14.4%) received 25–49 ml/(kg · day), and 418 (43.4%) received ≥50 ml/(kg · day) human milk for the first 4 weeks of life. Compared with infants receiving exclusive formula, those receiving the highest volume of human milk daily [≥50 mL/(kg · day)] had lower incidences of BPD [27.5% in ≥50 mL/(kg · day) vs 40.1% in 0 mL/(kg · day) human milk, P = 0.001)], moderate and severe BPD [8.9% in ≥50 mL/(kg · day) vs 16.1% in 0 mL/(kg · day), P = 0.004], necrotizing enterocolitis [NEC; 3.8% in ≥50 mL/(kg · day) vs 10.8% in 0 mL/(kg · day), P = 0.001], late-onset sepsis [LOS; 9.3% in ≥50 mL/(kg · day) vs 19.7% in 0 mL/(kg · day), P <0.01], and extrauterine growth retardation [EUGR; 38.5% in ≥50 mL/(kg · day) vs 57.6% in 0 mL/(kg · day), P <0.01)]. The logistic regression indicated that those receiving ≥50 ml/kg · day human milk had lower odds of BPD [adjusted odds ratio (AOR) 0.453; 95% confidence interval (CI): 0.309, 0.666], moderate and severe BPD (AOR 0.430; 95% CI: 0.249, 0.742), NEC (AOR 0.314; 95% CI: 0.162, 0. 607), LOS (AOR 0.420; 95% CI: 0.263, 0.673), and EUGR (AOR 0.685; 95% CI: 0.479, 0.979). Conclusions A daily threshold amount of ≥50 ml/(kg · day) human milk in the first 4 weeks of life was associated with lower incidence of BPD as well as NEC, LOS, and EUGR in VLBW infants.

Postnatal growth failure in preterm infants is due to interactions between genetic and environmental factors, which are not fully understood. We assessed dietary supply of nutrients in very-low-birth-weight (VLBW, < 1500 g) infants fed fortified human milk, and examined the association between nutrient intake, medical factors and growth during hospitalisation lasting on average 70 d. We studied 127 VLBW infants during the early neonatal period. Data were obtained from medical records on nutrient intake, growth and growth-related factors. Extra-uterine growth restriction was defined as body weight < 10th percentile of the predicted value at discharge. Using logistic regression, we evaluated nutrient intake and other relevant factors associated with extra-uterine growth restriction in the subgroup of VLBW infants with adequate weight for gestational age at birth. The proportion of growth restriction was 33 % at birth and increased to 58 % at discharge from hospital. Recommended values for energy intake (>500 kJ/kg per d) and intra-uterine growth rate (15 g/kg per d) were not met, neither in the period from birth to 28 weeks post-conceptional age (PCA), nor from 37 weeks PCA to discharge. Factors negatively associated with growth restriction were energy intake (Ptrend = 0·002), non-Caucasian ethnicity (P = 0·04) and weight/predicted birth weight at birth (Ptrend = 0·004). Extra-uterine growth restriction is common in VLBW infants fed primarily fortified human milk. Currently recommended energy and nutrient intake for growing preterm infants was not achieved. Reduced energy supply and non-Caucasian ethnicity were risk factors for growth restriction at discharge from hospital.

Background: Necrotizing enterocolitis (NEC) is the leading cause of gastrointestinal morbidity in preterm infants, and prevention and treatment strategies have remained largely unchanged over the past several decades. As understanding of the microbiome has increased, probiotics have been hypothesized as a possible strategy for decreasing rates of NEC, and several studies have noted significant decreases in rates of NEC after initiation of probiotics in preterm infants. However, a recent AAP report cited caution on the use of probiotic use in part because studies of probiotic use in ELBW infants are lacking. As our unit began routine use of probiotics for all infants &lt;33 weeks in 2015 and we are a leading institution for intact survival of ELBW infants, we attempted to answer if probiotic use can impact the rate of NEC in VLBW and ELBW infants.Methods: We conducted a single-center retrospective chart review of infants with modified Bell's stage ≥2a NEC for the 4 years prior to and 5 years after initiation of a protocol involving routine supplementation of a multispecies probiotic to premature infants at the University of Iowa, Stead Family Children's Hospital. The primary outcome measures were rates of modified Bell's stage ≥2a NEC and all-cause pre-discharge mortality at our institution before and after initiation of routine probiotic supplementation in 2015.Results: In our institution, neither the rates of modified Bell's stage ≥2a NEC, nor the rates of all-cause mortality were significantly altered in very low birth weight (VLBW) infants by the initiation of routine probiotic use (NEC rates pre-probiotic 2.1% vs. post-probiotic 1.5%; all-cause mortality rates pre-probiotic 8.4% vs. post-probiotic 7.4%). Characteristics of our two cohorts were overall similar except for a significantly lower 5-minute APGAR score in infants in the post-probiotic epoch (pre-probiotic 8 vs. post-probiotic 6 p = 0.0316), and significantly more infants in the post-probiotic epoch received probiotics (pre-probiotics 0% vs. post-probiotics 65%; p &lt; 0.0001). Similarly, probiotic use had no impact on the incidence of NEC when we restricted our data to only extremely low birth weight (ELBW) infants (pre-probiotics 1.6% vs post-probiotics 4.1%). When we restricted our analysis to only inborn infants, probiotics still had no impact on NEC rates in VLBW infants (1.5% pre- and 1.1% post-probiotic, p = 0.61) or ELBW infants (2% pre- and 2.1% post-probiotic, p = 0.99)Conclusions: Contrary to other studies, we found no significant difference in rates of modified Bell's stage ≥2a NEC or all-cause pre-discharge mortality in VLBW infants following routine administration of a multispecies probiotic supplement.

Necrotizing enterocolitis (NEC) is one of the most common and serious gastrointestinal diseases in preterm infants. The aim of this systematic review examines the effects of probiotics on preventing NEC in very-low birth weight (VLBW) infants with a focus on the Bifidobacterium species and its strains. A systematic review of randomized trials and retrospective studies analyzing the use of probiotics to prevent NEC in VLBW infants was conducted using PubMed, Cochrane Central Registry of Controlled Trials, and Google Scholar (1996–2016). Trials reporting NEC involving preterm infants who were given Bifidobacterium alone in the first month of life were included in the systematic review. Nine studies were suitable for inclusion. Nine studies involving VLBW infants were analyzed for strain specific effects of Bifidobacterium for the prevention of NEC ≥ Stage II. B breve showed some benefit in infants &lt; 34 weeks GA with relative risk (RR) of 0.43 (95% confidence interval [CI]: 0.21–0.87) p = 0.019, but not in neonates &lt; 28 weeks. B lactis greatly reduced the incidence of NEC with a RR 0.11 (95% CI: 0.03–0.47), p = &lt; 0.001. B bifidum was not widely studied but resulted in no cases of NEC. Bifidobacterium proved to be statistically significant in reducing the incidence of NEC in preterm infants.
