Donor human milk versus mother's own milk in preterm VLBWIs: a case control study.

As for term infants, over the past decades there has been increasing evidence of the benefits of human milk in the feeding of Very Low Birth Weight Infants (VLBWI), influencing not only short-term health outcomes but also long-term neurodevelopmental, metabolic outcomes, and growth. Mother's own milk is the first choice for all neonates including preterm infants, when it is unavailable or in short supply, pasteurized donor breast milk offers a safe alternative and is considered the next best choice. The main aim of this case-control retrospective analysis was to evaluate short term advantages of mother's own milk as a sole diet compared to donor milk as a sole diet, in terms of growth, antiinfectious properties, feeding tolerance, NEC and ROP prevention in a population of VLBWI born in a tertiary center. We did not find significant differences in clinical outcome from mother's own milk compared with pasteurized donor milk. Only a slight and statistically not significant difference in growth could be observed, in favour of maternal milk. We conclude that the maximum effort should always be put in supporting and promoting breastfeeding and donor milk used not only as an alternative to mother's milk but also as a breastfeeding promotion and support strategy.

Auxological evaluation of newborns.

Auxological evaluation of the newborn should be based on accurate anthropometry at birth and a reliable estimate of gestational age (GA). However, a comprehensive evaluation of the neonate should consider not only anthropometric traits at birth, but also fetal ultrasound biometry and Doppler velocimetry. Many charts have been proposed, but they are hardly comparable with each other, due to numerous methodological problems. The Italian Societies of Neonatology, of Pediatric Endocrinology and Diabetology and the Italian Society of Medical Statistics and Clinical Epidemiology promoted a multicenter survey with the aim to produce an Italian neonatal anthropometric reference (Italian Neonatal Study [INeS] charts) fulfilling the set of the criteria that a reliable neonatal chart should possess. In order to construct an international standard, an international project (INTERGROWTH-21st) has started a study aiming to create a prescriptive standard. Until an international standard is developed, the use of national updated reference charts is recommended.

Critical appraisal of different anthropometric charts to evaluate postnatal growth of preterm infants.

Preterm infants' survival has greatly increased in the last few decades thanks to the improvement in obstetrical and neonatal care. The correct evaluation of postnatal growth of these babies is nowadays of primary concern, although the definition of their optimal postnatal growth pattern is still controversial. Concerns have also been raised about the strategies to monitor their growth, specifically in relation to the charts used. At present, the charts available in clinical practice are fetal growth charts, neonatal anthropometric charts and postnatal growth charts for term infants. None of these, for different reasons, is suitable to correctly evaluate preterm infant growth. Recently, an international project has recently started aiming to create prescriptive standard for the evaluation of postnatal growth of preterm infants (INTERGROWTH-21st). Alternatively, at present, while specific charts for evaluating preterm infant postnatal growth are lacking, the best compromise is likely to be as follows: from birth to term neonatal anthropometric charts; International longitudinal charts WHO 2006 or CDC 2002 from term to childhood.

Hyperbilirubinemia and management of breastfeeding.

Hyperbilirubinemia and jaundice are natural, physiological phenomena which are only to be expected in the neonatal period, within certain limits. The highest percentage of jaundice in breastfed newborns should be evaluated in connection with inadequate management of breastfeeding rather than a direct effect of breast milk. Breastfeeding is also linked to visible jaundice persisting beyond the first two weeks of life (“breast milk jaundice”), but the appearance of skin jaundice is not a reason for interrupting breastfeeding which can and should continue without any interruption in most cases. There have been numerous contributions to the literature which have rescaled the direct role of breast milk both in early jaundice and in the more severe cases of late jaundice. The reviewed guidelines for detection and management of hyperbilirubinemia underline how prevention of badly managed breastfeeding and early support for the couple mother-child are effective prevention measures against severe early-onset jaundice; furthermore, the breastfeeding interruption is no longer recommended as a diagnostic procedure to identify breast milk jaundice because of its low specificity and the risk to disregarding the detection of a potentially dangerous disease.

Metabolism and biological functions of human milk oligosaccharides.

It is well known that breastfeeding is beneficial both for its nutritional properties and for the presence of biologically active compounds. Among these, human milk oligosaccharides (HMOs), representing the third largest fraction of human milk, have been assigned important biological functions, such as prebiotic and immunomodulatory and antimicrobial effects. HMOs are synthesized in the mammary gland by glycosyltransferase enzymes and can be divided in core-oligosaccharides, sialo-oligosaccharides, fucosyl-oligosaccharides and sialo-fucosyl-oligosaccharides on the basis of their chemical structure. Glycosyltransferases enzymes are partially regulated by genetic mechanisms; according to the expression of secretory and Lewis' genes, it is possible to classify human milk in 4 different secretory groups. We hereby present a review of the current knowledge concerning HMOs, their metabolism and main biological functions.

Functional Improvement After Outpatient Cardiac Rehabilitation in Acute Coronary Syndrome Patients is Not Related to Improvement in Left Ventricular Ejection Fraction.

INTRODUCTION: Cardiac rehabilitation (CR) improves the functional capacity and the prognosis of patients with coronary artery disease. AIM: Our study was aimed at assessing the relationship between functional improvement (evaluated with 6-min Walk Test-6MWT) and the improvement in left ventricular ejection fraction (LVEF) after CR. METHODS: We collected data from 249 patients (age 66.79 ± 11.06 years; males 81.52%) with a recent history of Acute Coronary Syndrome that performed CR. The functional improvement after CR was expressed as the Δ between distance covered at the final versus the initial 6-min Walking Test (6-MWT), while LVEF was calculated with transthoracic echocardiogram at the beginning and at the end of the CR. RESULTS: Patients were divided accordingly to their pre-rehab LVEF (≥ 55% vs < 55%). With superimposable age and baseline 6MWT distance covered (434.58 vs 405.12 m, p = 0.08), the latter group presented higher Δ meter values at 6MWT (167.93 vs 193.97 m, p = 0.018). However, no statistically significant positive correlation between Δ meters and Δ LVEF was found. Moreover, linear regression analyses found that nor baseline LVEF nor Δ LVEF were significant determinants of Δ meters when considering the whole group, with age, basal 6MWT and peak CK-MB as additional covariates in the model. CONCLUSION: Although it could be expected that an increase in LVEF is related to the functional improvement after CR, no significant correlation was found in our population.

Is breastfeeding duration influenced by maternal attitude and knowledge? A longitudinal study during the first year of life.

OBJECTIVE: To discuss the duration and types of breastfeeding and to identify the factors associated with the early introduction of formula milk. MATERIALS AND METHODS: This longitudinal study was conducted in the largest birthing centre of Turin. 562 mother-infant pairs were selected randomly and enrolled from among all the births that occurred in our Hospital from January to December 2009. Data was collected by means of a questionnaire filled out by the researcher during a face-to-face interview at mother's bed side during her hospital stay. This questionnaire included data regarding maternal socio-demographic, biomedical and hospital-related characteristics and some questions regarding family support, maternal attitude and current knowledge on breastfeeding. Mothers were interviewed by telephone at 1, 3, 6 and 12 months postpartum using the 24-h recall technique and definitions recommended by the WHO to investigate the type of breastfeeding adopted. RESULTS: At the age of 6 months only 8.9% of the infants involved were still exclusively breastfed and 44.3% had discontinued breastfeeding. By the age of 12 months 25.3% of infants were still receiving some breast milk. The main factors that had a negative impact on the duration of breastfeeding included maternal smoking habits, early pacifier introduction and the maternal infant feeding attitude. CONCLUSIONS: The rate of initiation and overall duration of breastfeeding reached the WHO objectives, but exclusive breastfeeding duration has still not reached satisfactory levels at 6 months. Given that the maternal infant feeding attitude is the only factor independently related to breastfeeding duration for the whole first year of life, reliable measures of maternal attitude could be used as a first step in targeting and assessing interventions that promote and sustain breastfeeding.

Drugs and breastfeeding: instructions for use.

It's universally well known that breastfeeding, due to its numerous beneficial effects on child and maternal health, is the best feeding method for infants. The use of medication by the nursing mother and the physician's advice to stop nursing are the most common reasons for the cessation of breastfeeding. The physician plays an extremely delicate role and should be able to assess risks and benefits for both mother and child. The issue of which drugs are safe to take during lactation is quite complicated. Three main factors must be taken into account: pharmacokinetics, assessment of the risk to the infant and to the lactation. Excellent sources of reliable information are the reference books. For the most up-to-date information it would be useful to consult the online medical literature. Few drugs have been demonstrated to be absolutely contraindicated during breastfeeding. Clear, safe and reliable information is still lacking for most drugs. It would be desirable to see an improvement in knowledge about mechanisms for transfer of drugs into milk, to analyze the biotransformation process for a given drug and to study the clinical consequences of infant exposure to drugs present in milk.

Postnatal growth of preterm infants: which reference charts?

Preterm Infants' survival has greatly increased in the last few decades thanks to the improvement in obstetrical and neonatal care. These neonates constitute the large majority of the population in neonatal intensive care units. The correct evaluation of postnatal growth of these babies is nowadays of primary concern, although the definition of their optimal postnatal growth pattern is still controversial. Concerns have also been raised about the strategies to monitor their growth,specifically in relation to the charts used. At present the available charts in clinical practice are fetal growth charts, neonatal anthropometric charts and postnatal growth charts for term infants. None of these, for different reasons, is suitable to correctly evaluate preterm infant growth. An international multicentric project has recently started a study aiming at building a prescriptive standard for the evaluation of postnatal growth of preterm infants and it will be available in the next years. At present, while an international longitudinal standard for evaluating preterm infant postnatal growth is lacking, in Italy the best compromise in clinical practice is likely to be as follows: new Italian INeS (Italian Neonatal Study) charts up to term; International longitudinal charts WHO 2006 or CDC 2002 from term to two years; finally, the Italian Society for Pediatric Endocrinology and Diabetes (SIEDP) 2006 growth charts could be suitable for monitoring the growth of these infants from two years up to 20 years of age.

Benign transient blueberry muffin baby.

In this case-report a case of severe fetal anemia of unknown origin is presented. Diagnosis of fetal anemia was made at 24 weeks of gestational age, when fetal ascites was identified. Doppler sonography of medium cerebral artery showed a high systolic speed velocity (ACM-PSV), of 65 cm/s (>1.55 MoM). This value predicts a severe fetal anemia. Funicolocentesis confirmed hyporegenerative anemia, low reticulocytosis and low erythroblastosis. A fetal transfusion was performed. At birth anemia was still present and the baby presented blueberry muffin and liver erythropoietic foci. The blueberry muffin morphology presents as non-blanching, blue-red macules or firm, dome-shaped papules (2-8 mm in diameter). The eruption is often generalized but favors the trunk, head, and neck. Infectious (Toxoplasmosis, Cytomegalovirus, Rubella, Herpes, Parvo, Coxackievirus, Ebstein Barr, Syphilis), hematologic (sferocytosis, alloimmunization, foeto-maternal transfusion), metabolic, neoplastic (congenital leukemia, neuroblastome, congenital rhabdomyosarcome) and systemic (histiocytosis, lupus) pathologies indicated until now as possible disease causes were excluded. In the first day of life the neonate received a RBC transfusion for anemia (Hb=5.1 g/dL; Hct 15,7% at birth), followed within 48-72 hours by rapid disappearance of the rash, that wasn't then histologically examined. During two weeks of hospitalization reticulocytes raised spontaneously from 0.8% to 3.17%. Until two years of age the auxologic and clinical course was regular and the child is now in good health conditions. Due to the absence of systematic disease and the complete regression, no exact diagnosis and prognosis could be established in this case.

Communicative strategies in a neonatal intensive care unit.

Counseling is a professional intervention based on skills to communicate and to build relationships. The project 'Not alone', related to counseling at our Neonatal Intensive Care Unit, is aimed to let counseling become a 'shared culture' for all the care givers. The first essential aspect is to form the ability of counseling through periodic courses for all professionals of the department (physicians, nurses, and physiotherapists). In our department, a professional counselor is present assisting the medical staff in direct counseling. The counselor's intervention allows a better parent orientation in the situation. A more effective sharing of these rules also facilitates the communication among parents and medical staff. Periodic meetings are established among the medical staff, in which the professional counselor discusses difficult situations to share possible communicative strategies. We wanted to have not only a common communicative style, but also common subjects, independent from the characteristics of each of us. Individuals are often faced with diverse situations. For every setting that we more frequently face in communication (for example the first interview with a parent of a very preterm infant) we have built an 'algorithm' that follows a pattern: (1) information always given; (2) frequent questions from parents; and (3) frequent difficulties in the communication. We also need to record important moments, for instance the 'case history of the communication': in fact it would be desirable to have the case history, a sheet dedicated to important communications that are absolutely to be shared with other professionals.
