Aim: To determine the impact of the protocol change from slow to fast enteral feeding progression on duration of central venous catheter placement, and the rates of late-onset sepsis and necrotising enterocolitis.
Methods: We compared the evolution of all very low-birth-weight infants admitted on their first postnatal day in neonatal intensive care unit during a 12-month period, before (2021 Cohort) and after (2022 Cohort) implementation of a new feeding protocol. Linear regression model was used to adjust for confounding factors.
Background: The presence of veterinary drug residues in food-producing animals and animal products is regulated through the enforcement of maximum residue limits (MRLs). To answer the need of the food sector to monitor these substances in a wide range of food commodities, stakeholders at AOAC INTERNATIONAL identified the need for a reliable confirmatory screening method. Such a qualitative approach is required for compliance checking and to support product release in manufacturing.

In a previous study, we provided as a first modeling approach a hollow fiber solar collector vacuum membrane distillation (VMD) module, considering a constant temperature at the shell side and a pure water feed. Here, a full model is developed to describe the coupled effects of the solar collector and a hollow fiber VMD module operating in an outside/in mode with saline water.

This study describes the extension of a gas chromatography mass spectrometry (GC-MS) method, initially devoted to the analysis of ethylene oxide (EO) in ice cream, to a larger range of food items including herbs, spices, vegetables, inorganic salts, food supplements, thickeners, etc. Results are reported as EO according to EC 2015/868 definition (expressed as EO equivalents as the sum of native EO and 2-chloroethanol (2-CE) after acidic hydrolysis) with a limit of quantification at 0.01 mg/kg regardless of the food item.

Aim: This study investigated whether an infant-cue based nurse educational feeding bundle accelerates the achievement of independent oral feeding in neonates in a neonatal intensive care unit.
Study Design: A quality improvement study with a pre, during and post intervention test design.
We aimed to investigate whether the participation in an observational study on breastfeeding (Doal) modified breastfeeding outcomes in enrolling neonatal intensive care units (NICUs). This bi-centric before-and-after study included neonates who were admitted during a 4-month period before and a 4-month period after the implementation of Doal. Breastfeeding intention and breastfeeding rates at discharge were compared between the two periods.

However, breastfeeding rates and duration are lower than among term infants. It is reported that peer counselling is effective in increasing breast feeding in term infants in low-income and middle-income countries, but results are mixed in high-income countries.

Objectives: This study aimed to describe the use of raw MOM in hospitalised neonates before day 7 (early use), and to investigate: (i) related factors, (ii) maternal satisfaction, and (iii) the association with breastfeeding continuation.
Methods: This prospective cohort included 516 neonates intended to be breastfed in 2 French neonatal units.
Introduction: Preterm neonates are particularly at risk of vitamin D (25-D) deficiency. To prevent rickets and osteopenia in this population, international guidelines vary between 800 and 1000IU per day of vitamin D in Europe and recommend 400IU per day in the USA. Target levels of circulating 25-D are not well identified, with the lower target level 50-75nmol/L and the upper target level probably 120nmol/L.

Studied compounds belong to several families: polybrominated diphenyl ethers, polychlorinated biphenyls, hexachlorobenzene, pentachlorobenzene, phthalates, polyaromatic hydrocarbons, parabens, tetrabromobisphenol A, bisphenol A, hexabromocyclododecane, triclosan, alkylphenols, alkylphenol ethoxylates, synthetic musks (galaxolide and tonalide) and pesticides (lindane and cypermethrin). A medium volume sampling system was used to collect simultaneously these endocrine-disrupting compounds (EDCs) from the gaseous and particulate phases.

Background: Intravenous nutrition preparations that are not photoprotected generate oxidants, which are deleterious for cell survival. The question remains: are these observations of clinical relevance in individuals receiving parenteral nutrition (PN), especially in those who exhibit immature antioxidant defenses such as premature infants?
Objective: To review clinical trials reporting the effect of light-exposed vs light-protected PN to determine whether photoprotection reduces neonatal mortality in preterm infants.
Data Source: Electronic databases, abstracts in relevant journals, and references in manuscripts between 1980 and 2014.
Background & Aims: Hyperglycemia occurs in more than half of the extremely low birth weight (ELBW) neonates during the first weeks of life, and is correlated with an increased risk of morbi-mortality. Hypophosphatemia is another frequent metabolic disorder in this population. Data from animal, adult studies and clinical observation suggest that hypophosphatemia could induce glucose intolerance.

Introduction: Oxidant stress is implicated in the pathogenesis of bronchopulmonary dysplasia (BPD). Light induces peroxide generation in parenteral nutrition (PN) solutions, creating an oxidant stress. Shielding PN from light decreases its peroxide content, which has nutrition and biochemical benefits in animals and humans.

As VMD is a pressure and temperature driven process, the idea of this work is to propose a new water vapour permeability measurement method based on variation of feed temperature at a fixed vacuum pressure. This new method showed a greater stability and simplicity than the existing pressure variation method by not only allowing a wide range of feed temperature (25 °C ÷ 60 °C) to be scanned continuously, but also avoiding fluctuations of the system as observed in the pressure variation test.

Low pressure membrane filtration such as ultrafiltration (UF) has been developed as a pre-treatment before reverse osmosis. However, UF alone may not be an effective enough pre-treatment because of the existence of low-molecular weight dissolved organic matter in seawater.

Regenerated cellulose membrane with 30 kDa and actual seawater from Mediterranean Sea were used. The coagulant was FeCl(3) and adsorbents were two PAC types, with different surface area and pore size distribution.

However, because of limitation by the osmotic pressure, a high recovery factor is not attainable. Consequently, large volumes of brines are discharged into the sea and the flow rate produced (permeate) is limited.

Design: Retrospective cohort study.
Aim: To determine malondialdehyde (MDA) concentrations in parenteral nutrition admixtures exposed to ambient room light, and in the serum of neonates.
Methods: Using a new method to measure MDA specifically, this study analysed MDA of lipid-containing all-in-one admixtures provided by the pharmacy, with a composition identical to that used in routine clinical conditions. First, 12 admixtures were exposed to ambient light for 24 h, in the neonatal intensive care unit.
