    ABSTRACT: Objective To investigate the efficacy of a proactive feeding regimen (PFR) in reducing hospital length of stay in a population of moderately preterm small for gestational age (SGA) infants. Study design SGA infants (z-score <−1.28) of gestational age (GA) 32-36 weeks and birth weight (BW) >1499 g were allocated at random to receive either a PFR, starting with 100 mL/kg/day and gradually increasing to 200 mL/kg/day by day 4, or a standard feeding regimen, starting with 60 mL/kg/day and gradually increasing to 170 mL/kg/day by day 9. All infants received human milk. Results A total of 72 infants were randomized to the 2 groups, 36 to the PFR group (mean GA, 35.1 ± 0.7 weeks; mean BW, 1761 ± 177 g) and 36 to the standard feeding regimen group (mean GA, 35.5 ± 1.2 weeks; mean BW, 1754 ± 212 g). Infants in the PFR group were discharged significantly earlier (mean, 9.8 ± 3.1 days vs 11.9 ± 4.7 days; P = .029). The need for intravenous fluids (2.8% vs 33.3%; P = .0013) and the incidence of hypoglycemia (0 vs 33.3%; P = .00016) were significantly lower in the PFR group. Feeding intolerance and fecal calprotectin levels did not differ between the 2 groups. Conclusion A PFR in moderately preterm SGA infants is well tolerated and significantly reduces both the length of stay and the risk of neonatal hypoglycemia.

    ABSTRACT: Whenever possible, oral feeding is the preferred method in neonatal feeding. However, many premature infants are unable to suck and swallow effectively; in these cases alternative methods of nutrient delivery must be used. We briefly review the different feeding methods used in neonatal units, with particular attention to their theoretical advantages, disadvantages and to the current best evidence available.

    ABSTRACT: Increased activity of the renin-angiotensin-aldosterone system (RAAS) has been reported in the neonatal period. Until now, it has been demonstrated that the RAAS of healthy neonates responds to acute furosemide challenge while no data concerning the responsiveness of RAAS in extremely low birth weight (ELBW) infants are available. To assess urinary aldosterone excretion (UAE) and renal function in ELBW infants who received diuretics for the purpose of reducing the incidence of chronic lung disease (CLD). Infants with birth weights < or =1,000 g, at high risk to develop CLD, were studied in a prospective observational study. UAE and renal function were investigated before and after administration of furosemide given in a single dose of 2 mg/kg. UAE and renal function were evaluated in 20 ELBW infants. Diuretic administration resulted in a significant rise in UAE and urinary sodium, potassium and chloride excretion. No change occurred in creatinine clearance, while urine volume increased significantly. ELBW infants respond to acute furosemide challenge by increasing urine volume, urinary electrolytes and UAE.

    ABSTRACT: Early provision of protein has been shown to limit catabolism and could improve growth. Our objective was to determine whether early aggressive protein intake improved growth outcomes of extremely low birth weight (ELBW) infants. ELBW infants were included in the study if they had no major congenital anomalies or renal failure and were still hospitalized at 36 weeks postmenstrual age. In 25 infants (HP) the early protein intake was planned to be 20% greater than in 31 historical controls (SP). The 2 groups were similar in the baseline characteristics. The mean protein intake during the first 14 days of life was significantly greater in the HP group (3.1 +/- 0.2 vs 2.5 +/- 0.2 g/kg/d; P<0.0001). HP group showed lower postnatal weight loss (-3.1%; 95% confidence interval [CI] -5.9, -0.2) and earlier regain of birth weight (-4.1 days; 95% CI -6.6, -1.7). Mean blood urea nitrogen and bicarbonate levels were similar; mean serum glucose level was lower in the HP group (-21,7 mg/dL; 95% CI -41.9,-1.5). HP infants had a reduced fall in weight z score (-0.57; 95% CI -1.01, -0.12) and in length z score (-0.51; 95% CI -0.97, -0.05) from birth to discharge. Early high protein intake was associated with improved weight and length growth outcomes at discharge. These findings highlight the benefits of aggressive protein intake immediately after birth.

    ABSTRACT: Background: Intraventricular hemorrhage (IVH), a common event in preterm infants, may also occur in utero with a suggested estimate of 1–5 in 10000 pregnancies. A high incidence of sequelae is reported in survivors but the data available so far have not been sistematically and prospectively collected with a structered assessment. The aim of this prospective study was to evaluate the presence and the severity of neurological and neurovisual impairment in a cohort of 13 infants with antenatal IVH and post-haemorrhagic ventriculomegaly.
