Objective: To estimate the incidence of hypophosphatemia in preterm infants according to parenteral nutrition received and to evaluate associated risk factors.
Design: A prospective multicenter cohort study included 111 patients ≤ 1250 g (7 NICUs of the NEOCOSUR Network). Two groups were compared according to the amino-acid supply in the first 48 h: aggressive parenteral group ≥ 3 g/kg/day and standard parenteral group: <2.9 g/kg/day. Hypophosphatemia was defined as serum phosphate < 4 mg/dl. A logistic regression analysis was performed to evaluate associated risk factors.
Results: Fifty-eight infants received aggressive parenteral nutrition. The incidence of hypophosphatemia was significantly higher in the aggressive parenteral group (77.5% vs 53.8%, p = 0.009). Hypophosphatemia was independently associated with aggressive parenteral nutrition (aOR 4.16 95% CI 1.54-12.24) and negatively associated with phosphorous intake (aOR 0.92 95% CI 0.87-0.97).
Conclusion: Both high amino-acid intake and low phosphorus supply during the first days after birth were independently associated with hypophosphatemia.
Objective: Necrotizing enterocolitis (NEC) classically is diagnosed by radiographic demonstration of pneumatosis intestinalis/portal venous gas (PI/PVG). This study examines clinical characteristics of NEC confirmed by independent evaluation of abdominal radiographs, taken for clinical signs of NEC, or by pathologic findings at laparotomy or autopsy (confirmed NEC [cNEC]).
Study Design: The investigated cohort included 1,382 extremely low birth weight (BW) infants (BW range: 500-1,000 g) with median 27 weeks (range: 23-32) gestational age (GA) at birth.
Aim: Late-onset sepsis (LOS) is common in extreme prematurity. These infants are at risk of refeeding syndrome-associated hypophosphataemia. Our objective was to investigate whether hypophosphataemia predisposes to LOS in extremely premature neonates.
High protein intake (HP) versus low protein intake (LP) was evaluated for its effects on neurodevelopment, growth, and biochemical issues in preterm infants, with findings based on 44 studies involving 5,338 children.
HP intake may reduce survival without neurodisability slightly but could increase risks of cognitive impairment and several metabolic complications, including hypophosphatemia and refeeding syndrome.
Overall, HP intake doesn't show significant long-term benefits for growth and may negatively impact neonatal metabolism and neurodevelopment, suggesting it shouldn't be recommended for premature infants.
Objectives: High protein parenteral nutrition (HPPN) in the early postnatal period is a recommended strategy for very low birth weight (VLBW) infants. However, limited data is available on electrolyte changes when HPPN strategy is utilized. We investigated the impact of HPPN on the development of hypophosphatemia and hypokalemia in preterm VLBW newborns.
Objective: The objective was to study the effect of early preventive calcium and phosphorus supplementation on metabolic bone disease in preterm infants.
Methods: A retrospective analysis of 234 preterm infants with a gestational age < 32 weeks or birth weight < 1500 g who were hospitalized in the Neonatology Department of the Second Hospital of Shandong University from 01.2018 to 12.
