Abstract
OBJECTIVES Gastroesophageal reflux may exacerbate chronic lung disease in preterm infants. We evaluated the short-term effects of transpyloric feeding on respiratory status in preterm infants during mechanical ventilation. METHODS We retrospectively collected data from the hospital information management system. To evaluate the effect of transpyloric feeding on oxygenation, we compared changes in SpO2/FiO2 ratios before and after commencing transpyloric feeding by a piecewise linear regression model. RESULTS We examined 33 infants (median gestational age, 25.4 weeks; median birth weight, 656 g) who underwent transpyloric feeding. All tubes were placed at the bedside without fluoroscopy. No cases of unsuccessful placement, gastroduodenal perforation, or tracheal misinsertion occurred. Transpyloric feeding began at a median age of 18 (interquartile range, 15-23) days. Mean SpO2/FiO2 (±SD) ratios were 391 (±49), 371 (±51), 365 (±56), and 366 (±53) 72-96 h before, 0-24 h before, 48-72 h after, and 96-120 h after starting transpyloric feeding, respectively. The rate of change per hour of SpO2/FiO2 ratios increased 48-120 h after compared with 0-96 h before transpyloric feeding (0.03 [95% confidence interval, -0.10 to 0.17] vs. -0.29 [-0.47 to -0.12]) (p=0.007). No apparent changes occurred in the mean airway pressure, amplitude pressure, or pCO2. CONCLUSIONS Transpyloric feeding during mechanical ventilation can prevent the deterioration of oxygenation without major complications at the stage of respiratory exacerbation in preterm infants.

Abstract
BACKGROUND Mother's own milk does not provide enough nutrients to feed a preterm baby born before 32 weeks' gestation; therefore, human milk fortifiers are needed. However, human milk fortifiers increase the osmolality, and enteral administration of high osmolality fluids has been associated with gastrointestinal symptoms. For this reason, it is necessary for laboratories to have a validated system in order to measure human milk osmolality. RESEARCH AIM The aim of this study was to validate the OM-6050 Station System for measuring the osmolality of fortified mother's milk samples. METHODS Osmolality was measured using the osmometer OM-6050 Station System. Milk samples from healthy mothers (N = 3) unfortified and with two fortifiers (Almirón Fortifier® or NAN FM85®), as well as a nutritional supplement (Duocal MCT®) were used in the validation study through precision and linearity analysis. RESULTS In the precision study the mean intra-assay coefficient of variation was 1.2% and 1.7% for mother's milk and fortified mother's milk, respectively. The mean inter-assay coefficient of variation was ≤ 1% in both cases. In the linearity study the regression analysis had a linear response to fortified mother's milk osmolality between 294 mOsm/kg and 539 mOsm/kg. CONCLUSION The osmometer OM-6050 Station was reliable for determining the osmolality of fortified and unfortified mother's milk. It may be useful in the clinical practices within Neonatal Intensive Care Units.

Abstract
Very low birth weight infants often demonstrate poor postnatal longitudinal growth, which negatively impacts survival rates and long-term health outcomes. Improving extrauterine growth restriction (EUGR) among extremely premature infants has become a significant focus of quality improvement initiatives. Prior efforts in the University of Massachusetts Memorial Medical Center neonatal intensive care unit were unsuccessful in improving the EUGR rate at discharge.

Effects on Gastroesophageal Reflux of Donkey Milk-Derived Human Milk Fortifier Versus Standard Fortifier in Preterm Newborns: Additional Data from the FortiLat Study. Nutrients 2020; 12:nu12072142. [PMID: 32708446 PMCID: PMC7400944 DOI: 10.3390/nu12072142] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 07/11/2020] [Accepted: 07/16/2020] [Indexed: 02/08/2023] Open
Abstract
Background: Feeding intolerance is a frequent diagnosis in very preterm infants. As seen in the FortiLat trial, human milk fortification with the new donkey milk-derived human milk fortifier (DF) seems to improve feeding tolerance in these infants. The aim of this study was to evaluate the effects of using the DF compared with bovine milk-derived fortifier (BF) on gastroesophageal reflux (GER) in very low birth weight (VLBW) infants. Methods: Over a total of 156 preterm infants were enrolled into the FortiLat trial (GA <32 weeks and birth weight <1500 g) and randomized into the BF arm or DF arm, and we selected all infants with clinical signs of GER and cardiorespiratory (CR) symptoms. All the infants underwent CR and multichannel intraluminal impedance and pH (MII/pH) monitoring associated with gastric ultrasound to evaluate GER and gastric emptying time. Results: 10 infants were enrolled, and 5 were in the DF arm. At MII/pH, infants enrolled into the DF arm showed a lower GER frequency than BF arm infants (p = 0.036). Half gastric emptying time was similar in DF and BF arm infants (p = 0.744). Conclusion: The use of donkey-derived human milk fortifier reduced the GER frequency and consequently should be recommended in infants with feeding intolerance.

Abstract
BACKGROUND Human breast milk (BM) fortification is required to feed preterm newborns with less than 32 weeks of gestation. However, addition of fortifiers increases osmolarity and osmolarity values higher than 450 mOsm/kg may be related to gastrointestinal pathology. Hence, fortifier selection and dosage are key to achieve optimal feeding. OBJECTIVES To compare the effect on osmolality of adding different fortifications, including recently developed formulations, to BM and to study evolution of osmolarity over time in supplemented BM. METHODS Frozen mature BM from 10 healthy mothers of premature newborns was fortified with each of the following human milk fortifiers (HMF): AlmirónFortifier®, NANFM85®, or PreNANFM85®. In addition, fortified BMs were modified with one of the following nutritional supplements (NS): Duocal MCT®, Nutricia® AminoAcids Mix, or Maxijul®. Osmolality of BM alone, fortified and/or supplemented was measured at 1 and 22 hours after their preparation. All samples were kept at 4°C throughout the study. RESULTS Osmolality of BM alone was close to 300 mOsm/kg and did not change over 22 hours. When equicaloric amounts of HMF AlmirónFortifier®, NANFM85®, and PreNANFM85® were added to BM, osmolality increased roughly to 480 mOsm/kg with the first two fortifiers and only to 433±6 mOsm/kg with the third one. Upon addition of any of four different NSs to BM modified with AlmirónFortifier® and NANFM85®, osmolality reached values greater than 520 mOsm/kg, while osmolality of PreNANFM85® with two out of the four NSs remained below 490 mOsm/kg. NSs supplementing carbohydrates and hydrolysed proteins resulted into a higher increase of BM osmolarity. Osmolality increased significantly with time and, after 22h, only BM modified with PreNANFM85® remained below 450 mOsm/kg. CONCLUSIONS Upon addition of the HMFs tested, BM osmolality increases significantly and keeps raising over time. All HMFs but the recently developed PreNAN FM85® at 4% exceed the AAP recommended threshold for osmolarity of 450 mOsm/kg. Addition of NSs to PreNAN FM85® at 4% significantly increases osmolality above 450 mOsm/Kg. Thus, using PreNAN FM85® at 5% may be preferable to adding nutritional supplements since nutritional recommendations by the ESPGHAN are reached with a lower increase in osmolality.

Abstract
OBJECTIVE In preterm neonates fed human milk, fortification may be adjusted by (1) optimization, based on growth rate and serum nutrient analyses, or (2) individualization, based on serial milk nutrient analyses. The primary aim was to determine whether individualized plus optimized nutrition (experimental) improves velocity of weight gain and linear growth from birth to endpoint (36 weeks postmenstrual age or discharge) when compared with optimized nutrition alone (controls). STUDY DESIGN Double-blinded parallel group randomized trial in 120 neonates <29 weeks gestational age (GA) or <35 weeks and small for GA (birth weight < 10th centile). RESULT Weight-gain velocity (13.1 ± 2.1, n = 57 controls, vs. 13.0 ± 2.6 g kg-1 day-1, n = 59 experimental, P = 0.87), linear growth (0.9 ± 0.2, n = 55, vs. 0.9 ± 0.2 cm week-1, n = 52, P = 0.90) and frequency of weight/length disproportion (2% vs. 2%, P = 0.98) were similar in both groups. CONCLUSIONS Individualized plus optimized nutrition does not improve weight gain, linear growth, or weight/length disproportion at endpoint versus optimized nutrition alone.

Abstract
Gastroesophageal reflux is common in young infants, particularly those born prematurely or with a history of medical complexity. The most recent clinical practice guidelines recommend the use of nonpharmacologic management strategies because of concerns about the safety of acid-reducing medications and a lack of evidence of their effectiveness. Our purpose in this article is to holistically review the pathophysiology of gastroesophageal reflux disease, identify symptom management targets, and describe nonpharmacologic strategies that nurses can implement and/or teach to parents to manage symptoms of gastroesophageal reflux. Strategies targeting stress, dysbiosis, food intolerances, feeding difficulties, and positioning are discussed. Nurses can work with families to identify factors contributing to gastroesophageal reflux disease and determine individualized strategies that can be used in lieu of, or in addition to, medication.

Abstract
Human milk analyzers can measure macronutrient content in native breast milk to tailor adequate supplementation with fortifiers. This article reviews all studies using milk analyzers, including (i) evaluation of devices, (ii) the impact of different conditions on the macronutrient analysis of human milk, and (iii) clinical trials to improve growth. Results lack consistency, potentially due to systematic errors in the validation of the device, or pre-analytical sample preparation errors like homogenization. It is crucial to introduce good laboratory and clinical practice when using these devices; otherwise a non-validated clinical usage can severely affect growth outcomes of infants.

Abstract
Gastroesophageal reflux and gastroesophageal reflux disease symptoms are common challenges for very low-birth-weight infants (<1500 g). These symptoms frequently result in feeding difficulties and family stress. Management of symptoms across healthcare disciplines may not be based on current evidence, and inconsistency can result in confusion for families and delayed interventions. The feeding relationship between infant and caregivers may be impaired when symptoms are persistent and poorly managed. An algorithm for managing gastroesophageal reflux-like symptoms in very low-birth-weight infants (from hospital discharge to 12 months corrected age) was developed through the formation of a multidisciplinary community of practice and critical appraisal of the literature. A case study demonstrates how the algorithm results in a consistent approach for identifying symptoms, applying appropriate management strategies, and facilitating appropriate timing of medical consultation. Application to managing gastroesophageal reflux symptoms in the neonatal intensive care unit will be briefly addressed.

Abstract
Gastroesophageal reflux (GOR) is very common among preterm infants, due to several physiological mechanisms. Although GOR should not be usually considered a pathological condition, its therapeutic management still represents a controversial issue among neonatologists; pharmacological overtreatment, often unuseful and potentially harmful, is increasingly widespread. Hence, a stepwise approach, firstly promoting conservative strategies such as body positioning, milk thickening, or changes of feeding modalities, should be considered the most advisable choice in preterm infants with GOR. This review focuses on the conservative management of GOR in the preterm population, aiming to provide a complete overview, based on currently available evidence, on potential benefits and adverse effects of nonpharmacological measures. Nonpharmacological management of GOR might represent a useful tool for neonatologists to reduce the use of antireflux medications, which should be limited to selected cases of symptomatic babies.

Abstract
Although gastroesophageal reflux (GER) is a very common phenomenon among preterm infants, its therapeutic management is still an issue of debate among neonatologists. A step-wise approach should be advisable, firstly promoting nonpharmacological interventions and limiting drugs to selected infants unresponsive to the conservative measures or who are suffering from severe GER with clinical complications. Despite of this, a concerning pharmacological overtreatment has been increasingly reported. Most of the antireflux drugs, however, have not been specifically assessed in preterm infants; moreover, serious adverse effects have been noticed in association to their administration. This review mainly aims to draw the state of the art regarding the pharmacological management of GER in preterm infants, analyzing the best piecies of evidence currently available on the most prescribed anti-reflux drugs. Although further trials are required, sodium alginate-based formulations might be considered promising; however, data regarding their safety are still limited. Few piecies of evidence on the efficacy of histamine-2 receptor blockers and proton pump inhibitors in preterm infants with GER are currently available. Nevertheless, a significantly increased risk of necrotizing enterocolitis and infections has been largely reported in association with their use, thereby leading to an unfavorable risk-benefit ratio. The efficacy of metoclopramide in GER's improvement still needs to be clarified. Other prokinetic agents, such as domperidone and erythromycin, have been reported to be ineffective, whereas cisapride has been withdrawn due to its remarkable cardiac adverse effects.

Abstract
OBJECTIVE Once critically ill, preterm infants have transitioned to enteral or oral feedings, it is common to mix oral medications with milk feedings. The osmolality of oral and intravenous drugs were tested in the 1980s and many were found to exceed the American Academy of Pediatrics (AAP) recommended limit (400 mOsm kg(-1) H(2)O). Many new milks and medications have entered the neonatal intensive care unit (NICU) since then. The objective of this study was to measure the osmolality of common milk-medication combinations administered in the NICU. STUDY DESIGN Common milk-medication mixtures were analyzed for osmolality by freezing point depression. RESULT Only Elecare (30 kcal per oz) exceeded AAP recommendations for osmolality in its unadulterated state. The addition of multivitamins alone resulted in an osmolality that exceeded 400 mOsm kg(-1) H(2)O. The cumulative addition of other medications resulted in some osmolalities >1000 mOsm kg(-1) H(2)O. CONCLUSION The coadministration of medications with milk products should be evaluated as a potential contributor to gastrointestinal intolerance of feedings in preterm infants.
