Iron supplementation of low birth weight infants reduces the risk of behavioral problems. However, due to the risk of adverse effects, iron supplementation of very preterm infants in the NICU should be individualized, considering birth weight, postnatal age, diet, and serum ferritin concentrations. Sodium intakes should be minimized during the first 3 days of life in very preterm infants to avoid hypernatremia. However, after 4 days of age, sodium supplements can reduce hyponatremia and improve growth. Adequate parenteral and enteral calcium and phosphorus intakes are crucial for the prevention of osteopenia of prematurity. Screening of serum phosphate concentrations is useful. Deficiencies of docosahexaenoic acid (DHA) and arachidonic acid (AA) are frequently observed in extremely preterm infants. A recent Swedish study suggests that combined DHA and AA supplementation may reduce the risk of severe ROP. When prescribing enteral and parenteral nutrition for preterm infants, it is important to consider micronutrients. Many preterm infants will need different micronutrient supplements.","PeriodicalId":18986,"journal":{"name":"Nestle Nutrition Institute workshop series","volume":"30 1","pages":"130-137"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90845310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of HMOs represents one of the largest differences in composition between breast milk and infant formula. Currently, progress in biotechnology allows the production of selected HMOs such as 2'-fucosyllactose (2'-FL) and lacto-N-neotetraose (LNnT), which are increasingly being added to infant formulas to narrow the difference between breast milk and formula. It is important to differentiate HMOs naturally occurring in human breast milk from those biotechnologically produced, which, while identical to HMOs in breast milk, do not originate from breast milk. This chapter summarizes basic facts about HMOs, findings from observational studies assessing the relationship between specific HMOs and clinical effects, and evidence from randomized controlled trials with structures identical to HMOs in breast milk added to infant formulas. Overall, the findings from some recently published trials provide reassurance that infant formulas supplemented with selected structures identical to HMOs, specifically 2'-FL with/out LNnT, are safe and well tolerated, and may have favorable effects on some health outcomes and medication usage.

Safe access requires special infrastructure, trained staff, sophisticated algorithms, and standard operating procedures as well as quality control measures. DM has limitations like low protein content and unpredictable composition of the other macronutrients, despite fortification frequently not meeting recommendations - both of them compromising growth. The first paragraph is devoted to COVID-19 and how it impacts processes of DM banking. The following paragraphs review aspects of \"pasteurization,\" \"safety audits/donor screening,\" and \"DM nutrient variability.\" In summary, (i) Holder pasteurization still is the most suitable procedure for milk banks, but high-pressure pasteurization or ultraviolet C irradiation conserve the unique properties of DM better and deserve more research to make it suitable for clinical routine. (ii) In regard to safety/screening, guidelines are valuable for safe DM bank operation, but they differ between legislations. There is a surprisingly high rate of non-disclosed donor smoking (0.3%, p > 0.05) and of adulteration of delivered DM (up to 2%, p < 0.05) not detected by standard donor screening procedures. Frequencies differ between remunerated and non-remunerated programs. (iii) Neonatal caregivers should be aware of unpredictable composition of DM. They should be trained on how these can be overcome to avoid negative impact on growth and long-term outcomes like (a) measuring and disclosing nutrient contents of delivered DM batches to customers, (b) implementing certain types of donor pooling to reduce the risk of macronutrient depleted DM, (c) additional supplementation using 0.3-0.5 g protein/100 mL seems to be reasonable, (d) adjusted fortification may help to improve growth, but is not efficient in all preterm infants, (e) target fortification seems to improve growth (and probably also neurodevelopmental index) compared to standard fortification, (f) more research and clinical studies are needed.","PeriodicalId":18986,"journal":{"name":"Nestle Nutrition Institute workshop series","volume":"76 1","pages":"57-71"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76082742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this narrative review, we provide an overview on the macronutrient content in mother's own milk and donor milk and how this can be enhanced by the various available multi-nutrient fortifiers. We describe their general compositions and formulation, as well as several of their theoretical and practical advantages and drawbacks. In addition, differences between standardized fortification, or a more individualized approach like adjusted and targeted fortification are discussed. The optimal strategy however remains to be elucidated, and more experimental well-powered studies are therefore urgently needed.

HMF provides a means to add additional protein, energy, and micronutrients, while maintaining HM as the main source of nutrition. Because of their rapid increase of lean body mass, preterm infants have much higher protein requirements than term infants. Recommendations on protein requirements of preterm infants are available, but protein quality - i.e. the amino acid (AA) profile in HMFs has not been systematically assessed. Present guidelines for enteral nutrition recommend protein intakes around 4 g/kg body weight (BW) for preterm infants <1,500 g, an intake that is not achievable with unfortified HM intakes <200 mL/kg BW/day. It is generally assumed that the AA profile of HM is the best reference for the AA profile of HMF. We calculated advisable intakes of AAs for preterm infants between 400-2,500 g which are based on AA increments of the fetus. Corrections for absorption, inevitable losses, oxidation, and variation of AAs in HM were introduced. Our calculations indicate that extremely low birth weight (ELBW <1,000 g) and very low birth weight (VLBW <1,500 g) infants have substantially higher AA requirements than low birth weight (LBW) infants growing from 1,900 to 2,400 g. In ELBW infants, daily intakes of the different indispensable AAs (IAA) with 4 g of (term) HM protein/kg BW range between 59 and 125% of the respective advisable intakes. Intakes of 7 IAAs and 3 conditionally indispensable AAs (CIAA) are below advisable intakes. On the other hand, with 4 g HM protein per kg BW/day, the IAAs isoleucine and leucine and some dispensable AAs are already supplied in abundance. In VLBW infants, daily intakes of the IAA methionine and 3 CIAAs are still below the advisable intakes. In LBW infants (<2,000 g) receiving 3.5 g HM protein per kg BW daily intakes of 1 IAA and 3 CIAAs would be too low. Preterm infants should receive HMFs which provide adequate amounts of AAs which are needed for their rapid growth and development while avoiding excessive intakes. In particular, very high AA requirements of ELBW infants are a challenge. AA composition of present HMFs for preterm infants should be reconsidered: spiking HMF protein with the AAs which are presently undersupplied or providing targeted AA-based HMF are options to further improve the AA profile in fortifiers.","PeriodicalId":18986,"journal":{"name":"Nestle Nutrition Institute workshop series","volume":"96 1","pages":"86-100"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86718336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fortification is recommended up to term for the normal-growing infant and up to 3 months in growth-retarded infants. After hospital discharge, some mothers may not want to pump, fortify, and bottle-feed the fortifier-milk mixture any longer. They desire to breastfeed their infants directly from the breast, but unfortunately, fortification often interferes with direct breastfeeding. Cup feeding is the most researched fortification method and appears to be safe but cannot be applied during nursing. Another alternative is the supplemental nursing systems, but only a few low-quality studies investigated the method, which is difficult to handle and requires a lot of nursing experience. The use of a finger feeder to administer a fortifier to preterm infants is a new method that enables mothers to exclusively breastfeed their infants and meet their nutritional needs. Mothers reported easy preparation and handling of the fortifier. More than 67% of the infants accepted the device and fortifier application during nursing very well. However, the development of further methods to augment preterm infant nutrition that does not interfere with breastfeeding is of great interest. Future efforts to enable fortification during breastfeeding must be linked to the development of ready-to-use devices containing liquid human milk fortification mixtures.","PeriodicalId":18986,"journal":{"name":"Nestle Nutrition Institute workshop series","volume":"IA-20 1","pages":"101-106"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84603930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Strategies maximizing early maternal breast milk (MOM) exposure and duration of MOM use are key given global health benefits of MOM, but few feeding trials use these as outcomes.

Little evidence supports choosing between route of gastric tube placement, bolus, or continuous feed delivery. Individual infants may have specific features that require individualized feed management, such as combinations of growth restriction, antenatal blood flow concerns, intensive supportive needs (including inotropes), and large open patent ductus arteriosus, currently poorly represented in feeding trials.
