Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Occurrence of at least one episode of alimentary intolerance, defined as the necessity to interrupt enteral feeding for more than 8 consecutive hours during the study period from T0 to T3 (day 21) | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Short-term outcome measures: 1.1. Number of alimentary intolerance episodes, measured using clinical protocol focused on feeding tolerance every day during observational period (T0-T3) 1.2. Number of feeding interruption episodes (even for periods shorter than 8 hours) , measured using clinical protocol focused on feeding tolerance every day during observational period (T0-T3) 1.3. Total hours of enteral feeding interruption, measured using clinical protocol focused on feeding tolerance every day during observational period (T0-T3) 1.4. Time required to reach full enteral feeding (150 ml/kg/d of enteral feeding), measured using evaluation of clinical records at discharge 1.5. Variation of anthropometric indices (weight, length and cranial circumference), measured using weight, length, cranial circumference scale during the study period and at 40 ± 1 weeks of postmenstrual age 1.6. Hospitalization duration, measured using evaluation of clinical records at discharge 2. Clinical indices, measured using clinical evaluation at discharge: 2.1. Necrotizing enterocolitis (NEC), classified following Bell stages 2.2. Suspected or diagnosed sepsis 2.3. Death 3. Analytical parameters, measured using specific tests conducted in laboratory analysis: 3.1. Calcium, phosphorus, alkaline phosphatase, BUN, creatinine and albumin, measured at T0, T1, T2 and T3 3.2. Amino acid profile in plasma and urine, measured at T0 and T3 3.3. Indices of metabolic acidosis (pH, BE, bicarbonates), measured at T0, T1, T2 and T3 4. Gastic emptying time, assessed using echography at T3 in patients with GERD symptoms 5. Gastroesophageal reflux, assessed using pH-impedance monitoring at T3 in patients with GERD symptoms 6. Urinary metabolomic profile, measured using NMR metabolomics at T0 and T3 7. Faecal analysis (calprotectin), measured using specific tests conducted in laboratory analysis at T0 and T3 8. Occurrence of other pathological events, measured using clinical evaluation during the study | — |
