ABSTRACT
BACKGROUND: Neonatal hypoglycemia is tightly related to adverse neurodevelopmental and brain injury outcomes. METHODS: A total of 195 infants who were born from diabetic mothers with a low blood glucose level (< 2.6 mM) within 0.5 h after birth were enrolled in this prospective cohort study. Of these, 157 infants who had neonatal hypoglycemia (group A) were followed up, and this group was further divided into A1 [blood glucose concentration (BGC) < 2.6 mM at < 2 h after birth], A2 (BGC < 2.6 mM at 2-24 h after birth), and A3 (BGC < 2.6 mM at > 24 h after birth). A total of 144 infants whose mothers had no high risk for gestational diabetes mellitus were followed up as the control group during the same period. The neurodevelopment of the infants was evaluated by the Gesell scoring method. RESULTS: The adaptability in the A2 and A3 subgroups was significantly lower than that in the control group (73.9 ± 6.6 vs. 87.9 ± 11.2; 71.5 ± 8.9 vs. 87.9 ± 11.2, respectively). There were significantly more mothers who used insulin during the perinatal period in A3 than in A1 and A2 (31% vs. 2%; 31% vs. 7.9%, respectively). The mothers of babies in subgroups A2 and A3 gained more weight than those of the control group (15.3 ± 1.9 kg vs. 11.1 ± 2.2 kg; 14.8 ± 2.6 kg vs. 11.1 ± 2.2 kg, respectively). CONCLUSIONS: Long and repeated neonatal hypoglycemia caused poor adaptability. The babies of mothers who used insulin or had a high weight gain during pregnancy were associated with severe or persistent neonatal hypoglycemia.

BACKGROUND: This study aimed to evaluate the effect of early probiotic administration on gut microflora and influence on feeding in pre-term infants. METHODS: A double-blind, randomized, controlled clinical study was conducted to assess the effect of probiotics [live, combined lactobacillus and bifidobacterium (LCB)] supplementation in pre-term infants. Sixty hospitalized pre-term babies were randomly assigned to two groups: a probiotics-supplemented group and the control group. The primary endpoint was measurement of lactobacillus and bifidobacterium in the gut. The secondary outcome was the rate of feeding intolerance. RESULTS: In the first weekend, the quantity of gut lactobacillus and bifidobacterium was significantly higher in the probiotics-supplemented group than in the control group [7.84 ± 0.35 versus 6.39 ± 0.53 (log copy number/g wet fecal weight), p = 0.013; 8.52 ± 0.23 versus 7.01 ± 0.48, p = 0.024, respectively]. In the second weekend, the amount of gut lactobacillus and bifidobacterium in the probiotics-supplemented group remained significantly higher (8.62 ± 0.28 versus 7.34 ± 0.59, p = 0.036 and 9.45 ± 0.64 versus 7.85 ± 0.43, p = 0.007, respectively). Fewer patients in the probiotics-supplemented group developed a feeding intolerance (13.3% versus 46.7%, p = 0.013). CONCLUSIONS: Probiotic supplementation in the hospitalized pre-term infants in the first 2 weeks of life resulted in higher amounts of lactobacillus and bifidobacterium in the gut and a concomitant lower rate of feeding intolerance.
