TL;DR: Early assigned parenteral intake of Ca 75 mg ·kg−1 · day−1 and P 44 mg · kg−1· day −1 significantly contributed to preventing short-term bone strength decline in preterm infants.
Abstract: Background and Aim:Very premature newborns have an increased risk of low bone mass and metabolic bone disease. Most longitudinal studies report a significant decline in bone strength in the first weeks after birth. The aim of the study was to evaluate whether higher early calcium (Ca) and ph

TL;DR: A practical approach for nutritional assessment in preterm infants under intensive care, based on anthropometric measurements and commonly used biochemical markers, is suggested, which could be proxies of body composition but need validation.
Abstract: A practical approach for nutritional assessment in preterm infants under intensive care, based on anthropometric measurements and commonly used biochemical markers, is suggested. The choice of anthropometric charts depends on the purpose: Fenton 2013 charts to assess intrauterine growth, an online growth calculator to monitor intra-hospital weight gain, and Intergrowth-21st standards to monitor growth after discharge. Body weight, though largely used, does not inform on body compartment sizes. Mid-upper arm circumference estimates body adiposity and is easy to measure. Body length reflects skeletal growth and fat-free mass, provided it is accurately measured. Head circumference indicates brain growth. Skinfolds estimate reasonably body fat. Weight-to-length ratio, body mass index, and ponderal index can assess body proportionality at birth. These and other derived indices, such as the mid-upper arm circumference to head circumference ratio, could be proxies of body composition but need validation. Low blood urea nitrogen may indicate insufficient protein intake. Prealbumin and retinol binding protein are good markers of current protein status, but they may be affected by non-nutritional factors. The combination of a high serum alkaline phosphatase level and a low serum phosphate level is the best biochemical marker for the early detection of metabolic bone disease.

TL;DR: This document provides evidence-based guidance for clinical practices involving PN prescribing, order review, and preparation using consensus prior to review and approval by the American Society for Parenteral and Enteral Nutrition Board of Directors.
Abstract: Background Parenteral nutrition (PN) is a high-alert medication available for patient care within a complex clinical process. Beyond application of best practice recommendations to guide safe use and optimize clinical outcome, several issues are better addressed through evidence-based policies, procedures, and practices. This document provides evidence-based guidance for clinical practices involving PN prescribing, order review, and preparation. Method A systematic review of the best available evidence was used by an expert work group to answer a series of questions about PN prescribing, order review, compounding, labeling, and dispensing. Concepts from the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) format were applied as appropriate. The specific clinical guideline recommendations were developed using consensus prior to review and approval by the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) Board of Directors. The following questions were addressed: (1) Does education of prescribers improve PN ordering? (2) What is the maximum safe osmolarity of PN admixtures intended for peripheral vein administration? (3) What are the appropriate calcium intake and calcium-phosphate ratios in PN for optimal neonatal bone mineralization? (4) What are the clinical advantages or disadvantages of commercially available premade ("premixed") multichambered PN formulations compared with traditional/customized PN formulations? (5) What are the clinical (infection, catheter occlusion) advantages or disadvantages of 2-in-1 compared with 3-in-1 PN admixtures? (6) What macronutrient dosing limits are expected to provide for the most stable 3-in-1 admixtures? (7) What are the most appropriate recommendations for optimizing calcium (gluconate) and (Na- or K-) phosphate compatibility in PN admixtures? (8) What micronutrient contamination is present in parenteral stock solutions currently used to compound PN admixtures? (9) Is it safe to use the PN admixture as a vehicle for non-nutrient medication delivery? (10) Should heparin be included in the PN admixture to reduce the risk of central vein thrombosis? (11) What methods of repackaging intravenous fat emulsion (IVFE) into smaller patient-specific volumes are safe? (12) What beyond-use date should be used for (a) IVFE dispensed for separate infusion in the original container and (b) repackaged IVFE?

Abstract: Некротизирующий энтероколит (НЭК) новорожденных — наиболее частая причина постнатальной критической ситуации воспалительного генеза. Долгое время в качестве синонимов НЭК фигурировали такие патологические состояния, как функциональная кишечная непроходимость, внутрибрюшной абсцесс, спонтанная перфорация подвздошной кишки, аппендицит, некротический колит новорожденных с перфорацией, ишемический энтероколит, инфаркт кишечника новорожденных. Таким образом, почти до второй половины прошлого века данное патологическое состояние не было очерчено как нозологическая форма. В настоящее время НЭК нашел свое место в МКБ-10 под рубрикой Р.77. С клинической точки зрения НЭК представляет собой широкий спектр вариантов течения заболевания: от случаев, заканчивающихся благополучно, без каких-либо последствий, до тяжелых форм, осложняющихся некрозом кишечника, перфорацией, перитонитом и сепсисом, приводящим, как правило, к летальному исходу.
