[How I explore… intrauterine growth restriction].

Intrauterine growth restriction (IUGR) is a common obstetrical condition (10 % of all pregnancies). Its origin is most often vascular, but it may also be a symptom of another fetal pathology (infectious, genetic, syndromic). Screening may be complicated due to the low sensitivity of the clinical examination as well as ultrasound.

Growth Benefits of Own Mother's Milk in Preterm Infants Fed Daily Individualized Fortified Human Milk.

The influence of types of human milk (HM)-raw own mother's milk (OMM), pasteurized OMM, and donor milk (DM)-was evaluated for growth in premature infants fed exclusively HM with controlled nutritional intakes using daily individualized HM fortification (IHMF). Growth and nutritional intakes were prospectively collected in preterm infants (<32 weeks) fed IHMF and compared in infants fed predominantly (≥75%) OMM and DM. The influence of HM types (raw OMM, pasteurized OMM, and DM) on growth were also evaluated in the whole population.

Serum Magnesium Levels in Preterm Infants Are Higher Than Adult Levels: A Systematic Literature Review and Meta-Analysis.

Magnesium (Mg) is an essential mineral in the body, impacting the synthesis of biomacromolecules, bone matrix development, energy production, as well as heart, nerve, and muscle function. Although the importance of Mg is evident, reference values for serum Mg (sMg) in pediatric patients (more specifically, in neonates) are not well established. This systematic literature review and meta-analysis (using 47 eligible studies) aims to quantify normal and tolerable ranges of sMg concentrations during the neonatal period and to highlight the factors influencing Mg levels and the importance of regulating sMg levels during pregnancy and birth.

[Newborn infants' first outpatient visit].

The focus on outpatient follow-up of newborn infants increases as the duration of hospital stay after birth decreases. The first outpatient visit addresses the adequacy of the home transition. Appropriate feedings are checked.

Use of donor milk in the neonatal intensive care unit.

Own mother's milk is the first choice in feeding preterm infants and provides multiple short- and long-term benefits. When it is unavailable, donor human milk is recommended as the first alternative. Donor milk undergoes processing (i.

[CA, P, AND MG POSTNATAL METABOLISM AND REQUIREMENTS IN PARENTERAL AND ENTERAL NUTRITION OF PREMATURE INFANTS].

During the last trimester of gestation, transplacental mineral transfer and fetal mineral accretion is particularly high: 2.3-3.2 mmol/kg/day (90-130 mg/kg/d) of calcium, 2.

Electrolyte and Mineral Homeostasis After Optimizing Early Macronutrient Intakes in VLBW Infants on Parenteral Nutrition.

Objectives: The aim of the present study was to evaluate electrolyte and mineral homeostasis in very-low-birth-weight (VLBW) infants who received high protein and energy intakes with a unique standardized parenteral nutrition solution containing electrolytes and minerals from birth onward.

Methods: Prospective cohort study in 102 infants with birth weight <1250 g. The evolution of plasma biochemical parameters was described during the first 2 weeks of life.

[How I explore and treat a neonatal renal vein thrombosis: a case report].

Neonatal renal vein thrombosis is a rare condition. The present case is rather unfrequent and particularly educative since it shows the complete diagnostic triad including hematuria, flank mass and thrombocytopenia. The diagnosis relies on the demonstration, by Doppler ultrasound, of an obstructed renal venous bed.

Prematurity and bone health.

Recent advances in neonatal care significantly increases survival rate in preterm and particularly in extremely low birth weight infants (ELBW infants) and nutrition is becoming one of the most challenging issue to improve short and long term health and developmental outcomes. Nutrition is also relevant for bone development and mineralization reducing the risk of osteopenia and metabolic bone disease (MBD). Osteopenia of prematurity is a multifactorial disease including predominantly nutritional but also biomechanical and environmental factors.

Evaluation of specificity of tuberculosis diagnostic assays in caprine flocks under different epidemiological situations.

The aim of this study was to evaluate the specificity of the most widely used tuberculosis (TB) diagnostic tests, single intradermal tuberculin (SIT) and single comparative intradermal tuberculin (SCIT) tests and interferon-gamma (IFN-γ) assay in 937 animals from eight TB-free caprine flocks under different epidemiological situations. Maximum specificity was found using SCIT test (99.4-100% depending on the interpretation criteria) while SIT test and IFN-γ assay showed a slightly lower overall specificity (97.

[Early nutrition, postnatal growth retardation and outcome of VLBW infants].

Early nutrition is an important determinant of growth, morbidity and psychomotor development in very low birth weight infants. Recent data suggest that "aggressive nutrition" providing early and high protein supply from the first hours of life improves nitrogen balance, reduces postnatal growth retardation, decreases morbidity and is positively related to psychomotor development. This paper will summarize the metabolic bases of this optimal nutrition for preterm infants.

Enteral calcium, phosphate and vitamin D requirements and bone mineralization in preterm infants.

Unlabelled: With major advances in life-support measures, nutrition has become one of the most debated issues in the care of very low birth-weight (VLBW) infants. Current nutritional recommendations are based on healthy premature infants and designed to provide postnatal nutrient retention during the 'stable-growing' period equivalent to the intrauterine gain of a normal foetus. However, this reference is still a matter of discussion, especially in the field of the mineral requirements.

[Evaluation of the bacteriologic quality of breast milk in a neonatology service in Belgium].

Many studies demonstrated that human milk is the recommended source of enteral nutrition in preterm infants providing several benefits with regards to feeding tolerance, immunity and cognitive development However, neurological immaturity and associated clinical conditions prevent them from suckling effectively. Therefore, mother's milk must be expressed, stored and transported to the neonatal unit and could be contaminated. The microbiological quality of human milk was evaluated on each donation to the neonatal intensive care unit of the University of Liege, Belgium from November 1, 2003 to January 31, 2005.

[Prader-Willi syndrome: specific management by a multidisciplinary team].

Prader Willi syndrome can be viewed as a physiopathological model of obesity. Such patients deserve specific management, preferably in a multidisciplinary setting. The paper reports on 6 patients followed in the paediatric endocrine service at the University of Liege.

Software and scan acquisition technique-related discrepancies in bone mineral assessment using dual-energy X-ray absorptiometry in neonates.

Aim: In adults, whole-body mineralization assessment by dual-energy X-ray absorptiometry can be affected by the densitometer and/or the software used. As there are no published data on neonates, the aim of this study was to evaluate the magnitude of such effects in growing preterm infants.

Methods: We analysed the absorptiometry results obtained from 44 preterm infants scanned at discharge and again 6 wk later using densitometers from the same manufacturer equipped with "Pediatric" (Group A, n = 24) or with "Infant" (Group B, n = 20) packages.

Body composition in preterm infants fed standard term or enriched formula after hospital discharge.

Background: Most preterm infants are still preterm and have a low birth weight when they are discharged from the hospital. An important issue is whether the long-term consequences of early growth restriction can be diminished by nutritional intervention in preterm infants after discharge from the hospital.

Aim: To evaluate differences in growth and in weight gain composition of preterm infants fed standard term formula (SF) or enriched formula (PDF) after discharge from hospital during the first 2 months of life.

Nutritional assessment in preterm infants with special reference to body composition.

In recent years, improvements in care have significantly improved survival in preterm and, particularily, the very low birth weight infant (VLBW). While immediate survival can be directly related to pulmonary maturity, several studies stress the importance of timely and adequate nutrition in these high-risk infants on a short- and long-term [1]. Yet, nutritional support remains a very controversial issue in these high-risk infants.

Evaluation of weight gain composition during the first 2 months of life in breast- and formula-fed term infants using dual energy X-ray absorptiometry.

Healthy term breast- and adapted formula-fed infants show similar weight gain and weight gain composition during the first months of life.

Weight gain composition in preterm infants with dual energy X-ray absorptiometry.

Whole body composition was investigated using dual energy x-ray absorptiometry in 54 healthy preterm infants, birth weight < 1750 g, who were fed fortified human milk (n = 20) and preterm formula (n = 34) when full enteral feeding was attained and then again 3 wk later at around the time of discharge. Weight gain composition was calculated from the difference between the earlier and later measurement. The minimal detectable changes in whole body composition over time according to the variance of the population (within groups of 20 infants) and the minimal detectable changes according to the dietary intervention (between two groups of 20 infants) were determined at 5% significance and 80% power.

Bone mineral metabolism in the micropremie.

Environmental factors, nutritional supplies, hormonal status, diseases, and treatments appear to affect postnatal skeletal growth and mineralization in VLBW infants. Compared with their term counterparts, ELBW infants are at risk of postnatal growth deficiency and osteopenia at the time of hospital discharge. From recent data, DXA is becoming one of the reference techniques to evaluate mineral status, whole-body composition, and effects of dietary manipulations on weight gain composition and mineral accretion in preterm infants.

Effect of fortification on the osmolality of human milk.

Aim: To evaluate the effect of fortification on the osmolality of human milk.

Methods: The osmolality of 47 samples of human milk was determined at baseline, just after, and 24 hours after supplementation with five different human milk fortifiers (HMF) at 4 degrees C.

Results: Ten minutes after HMF supplementation the osmolality of human milk was significantly higher than the sum of the respective values of HMF dissolved in water and human milk, measured separately at baseline (p<0.

[Surveillance of the very-low birthweight infant: growth and nutrition].

In very low birth weight (VLBW) infants careful growth and nutritional supervision are necessary in order to reduce the incidence of persistent growth retardation after 2 to 3 years of age. Recently, post-discharge formulas with higher protein, energy and mineral content has been developed with the aim to promote catch up growth and mineral accretion during the first months of life. Based upon the most recent nutritional and growth data, the authors propose guidelines for the nutrition and growth follow-up of VLBW infants after discharge from the neonatal unit.
