ABSTRACT
Neonatal nutritional supplements are widely used to improve growth and development but may increase risk of later metabolic disease, and effects may differ by sex. We assessed effects of supplements on later development and metabolism. We searched databases and clinical trials registers up to April 2019. Participant-level data from randomised trials were included if the intention was to increase macronutrient intake to improve growth or development of infants born preterm or small-for-gestational-age. Co-primary outcomes were cognitive impairment and metabolic risk. Supplementation did not alter cognitive impairment in toddlers (13 trials, n = 1410; adjusted relative risk (aRR) 0.88 [95% CI 0.68, 1.13]; p = 0.31) or older ages, nor alter metabolic risk beyond 3 years (5 trials, n = 438; aRR 0.94 [0.76, 1.17]; p = 0.59). However, supplementation reduced motor impairment in toddlers (13 trials, n = 1406; aRR 0.76 [0.60, 0.97]; p = 0.03), and improved motor scores overall (13 trials, n = 1406; adjusted mean difference 1.57 [0.14, 2.99]; p = 0.03) and in girls not boys (p = 0.03 for interaction). Supplementation lowered triglyceride concentrations but did not affect other metabolic outcomes (high-density and low-density lipoproteins, cholesterol, fasting glucose, blood pressure, body mass index). Macronutrient supplementation for infants born small may not alter later cognitive function or metabolic risk, but may improve early motor function, especially for girls.

Neonatal nutritional supplements may improve early growth for infants born small, but effects on long-term growth are unclear and may differ by sex. We assessed the effects of early macronutrient supplements on later growth. We searched databases and clinical trials registers from inception to April 2019. Participant-level data from randomised trials were included if the intention was to increase macronutrient intake to improve growth or development of infants born preterm or small-for-gestational-age. Co-primary outcomes were cognitive impairment and metabolic risk. Supplementation did not alter BMI in childhood (kg/m2: adjusted mean difference (aMD) -0.11[95% CI -0.47, 0.25], p = 0.54; 3 trials, n = 333). Supplementation increased length (cm: aMD 0.37[0.01, 0.72], p = 0.04; 18 trials, n = 2008) and bone mineral content (g: aMD 10.22[0.52, 19.92], p = 0.04; 6 trials, n = 313) in infancy, but not at older ages. There were no differences between supplemented and unsupplemented groups for other outcomes. In subgroup analysis, supplementation increased the height z-score in male toddlers (aMD 0.20[0.02, 0.37], p = 0.03; 10 trials, n = 595) but not in females, and no significant sex interaction was observed (p = 0.21). Macronutrient supplementation for infants born small may not alter BMI in childhood. Supplementation increased growth in infancy, but these effects did not persist in later life. The effects did not differ between boys and girls.

Levetiracetam is a new anti-epileptic drug that is currently not licensed for use in children. Studies in adults suggest that it may be a useful adjunctive treatment both in partial onset and generalised epilepsy. A retrospective case notes review of 26 children age 10 years and under with refractory epilepsy was undertaken to evaluate the efficacy and safety of the drug. The drug appeared to be most effective in children with partial onset seizures and least effective in those with myoclonic seizures. Sixty-one percent of patients showed a good response to levetiracetam with at least a 50% reduction in seizure frequency with two of these 26 children with previously refractory epilepsy becoming seizure-free. Levetiracetam was also found to be well-tolerated with very few reported side-effects.

A 7-year-old female presented with Mycoplasma pneumoniae pneumonitis and a progressive ascending limb paralysis. She developed severe respiratory distress, requiring ventilation, and became apparently unresponsive with fixed dilated pupils. Peripheral nerves were inexcitable in nerve-conduction studies. Magnetic resonance imaging of the brain revealed evidence of extensive demyelination. Anti-GM1 immunoglobulin M antibody titers were raised. She improved after a second course of intravenous immunoglobulin and eventually made a full recovery.
