AIM: To assess the variation in size of the thymus in vivo in preterm neonates and to identify relations between thymic size and gestational age (GA), birthweight, occurrence of postnatal infections and maternal alcohol and tobacco intake during pregnancy. METHODS: Eighty preterm neonates with a GA between 24 and 36 wk, and a birthweight between 490 and 4110 g were examined between days 0 and 19 after birth. The thymic size was assessed by sonography as a volume estimate, the so-called thymic index (Ti). The median Ti was 5.2 (1.2-17.9). Ti was positively correlated with birthweight and GA and negatively correlated with occurrence of postnatal infection (p < 0.01, p = 0.03, p = 0.05, R2 = 0.68). A correlation between thymic size and maternal alcohol and tobacco intake was not demonstrated. CONCLUSION: It is possible to assess the size of the thymus by sonography in very low-birthweight and preterm neonates. A normal range for Ti in preterm neonates has been established. The sonographic method is a safe and effective technique for measuring the size of the thymus in preterm infants. 相似文献

Aim: To determine whether growth, feeding tolerance and infectious events of preterm infants is related to the proportion of intake of mother’s own raw milk (maternal milk) versus pooled pasteurized banked breast milk (donor milk). Methods: This is a prospective observational study of 55 premature infants born less than 32 weeks of gestational age admitted to the neonatal intensive care unit at the Children’s Hospital of Toulouse during two 6‐month periods from 2003 to 2005. Enrolled infants were exclusively on enteral feeds with maternal milk ± donor milk. Results: Mean gestational age was 28.6 weeks (SD 1.5) and mean birth weight 1105 grams (SD 282). During the time of exclusively breast milk feeds, weight gain (g/kg/day) was correlated to the proportion of maternal milk consumed (p = 0.0048, r = 0.4). Necrotizing enterocolitis was inversely correlated to the amount of maternal milk. The amount of maternal milk did not impact on infectious events. Conclusion: Mother’s own raw milk improves weight gain compared with donor milk in preterm infants. Lactation strategies should be sought that helps mothers to increase their milk production. 相似文献

Human milk (HM) is considered to be the optimal feed of choice for neonates, however, for preterm infants, HM fortifiers are often added to increase growth. If HM is unavailable, preterm formula is the next best option for preterm infants. Choosing which fortifier, if any, to use or which formula can be confusing. In this paper, the composition of milk feeds available in Australia and New Zealand is reviewed with the aim of assisting paediatricians to decide which feed is most appropriate for their patients. 相似文献

The concentrations of protein nitrogen (PN), non-protein nitrogen (NPN), energy, fat, sodium (Na), calcium (Ca), phosphorus (P), magnesium (Mg), and zinc (Zn) were determined in human milk from mothers giving birth to full-term (n = 13) and preterm infants (n = 8). Milk samples were collected under controlled conditions at two-week intervals for 12 weeks postpartum. Statistically significant differences in PN, Ca, and P concentrations were detected between the milk from mothers of preterm and term infants. The mean PN concentration in the preterm milk was statistically higher than that of term milk (198 vs. 164 mg N/dl), in contrast to the lower mean Ca (220 vs. 261 mg/1) and P (125 vs. 153 mg/1) concentrations detected in the preterm milk. No other differences in mean nutrient concentration were observed between the two groups. Concentrations of PN, NPN, Na, P, and Zn decreased over time. The concentration of Mg increased slightly. The content of fat, energy, and Ca did not change. 相似文献

The objective of this prospective, cohort study was to compare the nutritional status of full-term infants who were fed human milk (BF, n = 29). formula (FF, n = 30) or evaporated milk formulae (EM, n = 30) for at least 3 months. Infants were seen at enrollment, 3 and 6 months, at which times a blood sample, diet record and anthropometric data were collected. Infants in the EM group received solids earlier (12 ± 5 weeks) than did FF infants (15 ± 4 weeks), and both were earlier than BF infants (19 ± 4 weeks). Only 26% of the EM fed group received iron supplements as ferrous sulphate drops. Seven BF, 12 FF and 20 EM had abnormal ferritin values (<10ngml-1 ) at 6 months. Copper intake was lower in the EM infants at 3 and 6 months. However, plasma copper and erythrocyte copper zinc superoxide dismutase (ZnCuSOD) levels did not differ between groups. Selenium intake was lower in the EM group (5 ± 1 and 10 ± 5 μg d-1 ; 3 and 6 months) than in the FF infants (13 ± 4 and 19 ± 7 μgd-1 ; 3 and 6 months). Erythrocyte SeGHSPx levels in EM infants were lower at 6 months (EM, 33.2 ± 3.4; FF, 35.2 ± 3.9; BF, 36.1 ± S.SmUmgHb-1 ). Thiamin intake (0.99 ± 0.08 and 1.24 ± 0.32; 3 and 6 months, mg 1000 kcal-1 ) was higher in the FF group than in EM infants (0.38 ± 0.39 and 0.66 ± 0.38; 3 and 6 months). There were more (13%) abnormal thiamin assays in the EM group at 6 months than in the BF and FF infants (0%). In conclusion, infants fed evaporated milk formula receive adequate copper but may not receive enough thiamin or selenium. Unless supplemented from birth with medicinal iron, intakes of iron will be inadequate. 相似文献

Background: Phospholipids (PLs) play an essential role in the growth and brain development of infants. Aim: To investigate PL composition in human milk (HM), including lysophosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylserine, phosphatidylcholine (PC) and sphingomyelin (SM), from healthy Japanese mothers. Analyses were performed on colostrum, transitional milk and mature milk from mothers of preterm and term infants. Methods: HM samples were collected from mothers of 15 term infants (term group) and of 19 preterm infants (preterm group). PL composition was determined by two-dimensional thin-layer chromatography in conjunction with phosphorus analysis. Results: In both groups, the PL content (% of total lipid) of mature milk was significantly lower than in colostrum. SM and PC were the main PLs in HM, but in the preterm group, the percentage of SM in mature milk was significantly higher and PC in mature milk was significantly lower than in the term group.
Conclusion: The transition from colostrum to mature milk leads to an increase in SM and a decrease in PC in the HM of preterm infants, along with a decrease in PL content. This is the first report to demonstrate the differences in PL composition in HM between mothers of preterm and term infants. 相似文献

The study was designed to compare two different human milk fortifiers in a group of very low birth weight (VLBW) infants by analysing nitrogen and fat balances, serum concentrations of alpha-amino-nitrogen, urea, and prealbumin as well as growth rates when human milk enriched with one of the two studied fortifiers was fed to the infants. Fortifier A contained different bovine proteins, peptides and amino acids and had an amino acid composition comparable to that of the nutritional available proteins in human milk, with carbohydrates, and minerals. Fortifier B was composed of freeze-dried skimmed human milk and minerals to achieve a similar macronutrient composition in both fortifiers.Eleven infants were fed with human milk enriched with fortifier A and 13 with fortifier B. After a 10-day equilibration period, a 3-day metabolic balance was performed. On the 14th day of the study blood was obtained preprandially for serum analysis and growth rates were estimated. The nitrogen absorption rate (93.8% vs 93.5%) as well as the retention rate (80.8% vs 78.5%) were no different between the groups. The fat absorption rate (92.3% vs 91.5%) as well as the weight gain (32.1 vs 31.1 g/day) were similar and there were no differences in the serum parameters studied. The results indicate that feeding VLBW infants with human milk enriched with a well-balanced bovine fortifier fulfil their nutritional requirements as well as diets composed exclusively of human milk protein. 相似文献

BACKGROUND: Despite the protective effects of human milk against necrotizing enterocolitis, the incidence is highest in the extremely premature infant, and only minimally decreased with feeding human milk. This suggests that certain protective agents may be lower in milk from mothers delivering extremely premature infants. The anti-inflammatory cytokine IL-10 was one possibility. AIM: We hypothesized that low concentrations of IL-10 in preterm milk contribute to the development of necrotizing enterocolitis in extremely premature infants. METHODS: IL-10 in human milk collected at weeks 1, 2, and 4 postpartum was measured by ELISA in mothers of infants born extremely premature at 23-27 wk gestation (group EP), premature at 32-36 wk gestation (group P), and term at 38-42 wk gestation (group T). Single milk samples were collected from a separate group of mothers whose infants developed necrotizing enterocolitis. RESULTS: There were no significant differences in concentrations of milk IL-10 among groups EP, P, or T. Concentrations of IL-10 declined as lactation progressed (p < 0.001). IL-10 in milk was frequently undetected in all groups, but even more so in the milk of the group of women whose infants had necrotizing enterocolitis (86%) than in groups EP (40%) and P (27%) (p < 0.01). CONCLUSION: IL-10 was present in preterm milk from most women, and the concentrations in preterm and term milk were not significantly different. A paucity of IL-10 in human milk was found in certain mothers in each group, especially in those whose infants developed necrotizing enterocolitis. 相似文献

Aims: The aims of the study were to determine human breast milk adiponectin concentration and to investigate its relationship with serum adiponectin concentration in lactating mothers and their infants and also to evaluate the relationship between serum adiponectin concentration and anthropometric parameters in nurses and infants. Methods: We enrolled 60 healthy term breastfed (BF) infants and their lactating mothers. Adiponectin was determined by radioimmunoassay test in serum and by enzyme‐linked immunosorbent assay test in human milk (HM). Infants’ and mothers’ anthropometric parameters were measured. Results: Median (25‰, 75‰) adiponectin concentration in HM was 9.99 (3.59, 20.52) ng/mL. Serum adiponectin concentration in infants was 60.49 (45.76, 74.24) μg/mL and in lactating mothers 21.14 (12.61, 29.66) μg/mL. Adiponectin concentration in HM correlated positively with adiponectin in mothers’ serum; r = 0.60 (p < 0.001) and in infants’ serum r = 0.37 (p = 0.015). Adiponectin in HM correlated negatively with infants’ age r = ?0.3 (p = 0.04). Infants’ serum adiponectin correlated negatively with their weight r = ?0.35 (p = 0.005), length r = ?0.35 (p = 0.006) and age r = ?0.46 (p < 0.001) and mothers’ serum adiponectin with their weight r = ?0.37 (p = 0.02) and body mass index r = ?0.45 (p = 0.004). Conclusions: The observed correlations between adiponectin in mothers, HM and BF infants may be suggestive for a metabolic link between nurses and infants through milk. 相似文献

At present, not much is known about the absorption and metabolism of human milk (HM) oligosaccharides in term and preterm infants. We investigated the renal excretion of lactose and complex oligosaccharides in preterm infants fed HM ( n = 9, mean actual body weight 2290 g) or a cow's milk-based infant formula ( n = 9, mean actual body weight 2470 g). We found that the renal excretion of lactose in HM-fed infants was slightly lower than in formula-fed infants (14.0 ± 7.4 versus 20.4 ± 8.7 mg kg-1 day-1 , mean ± SD). The excretion of neutral sugars deriving from oligosaccharides was similar in HM-fed and formula-fed infants (3.8 ± 2.1 versus 2.9 ± 0.9mgkg-1 day1- ); the difference between means was not statistically significant. The separation and characterization of oligosaccharides by high-pH anion exchange chromatography with pulsed amperometric detection (HPAE-PAD) and subsequent analysis by fast atom bombardment-mass spectrometry (FAB-MS) revealed a more complex pattern in HM-fed infants compared to the formula-fed group. Lactose-derived oligosaccharides characteristic for HM (e.g lacto- N -tetraose, and lacto- N -fucopentaoses I and II) were excreted in HM-fed but not in formula-fed infants. These results indicate that nutrition has a significant impact on the oligosaccharide composition in urine of preterm infants. 相似文献

Human milk (HM) banks provide pasteurised milk from screened donors for infants in many countries but not in Australia. There are potential benefits and risks from feeding donor milk with the benefits most likely for preterm infants. A randomized clinical trial is required to provide conclusive evidence. Promotion of breast-feeding with the establishment of HM banks may prove to be an important primary health care activities for infants in Australia. 相似文献

Aim: To evaluate the enteral feeding practice of preterm infants <32 weeks (W) gestational age (GA) or <1500 g birth weight (BW) from human cytomegalovirus (HCMV)‐seropositive mothers in Germany, Austria and Switzerland. Methods: This prospective cross‐sectional study included all neonatal units (NU) admitting preterm infants <32W or <1500 g BW in Germany, Austria and Switzerland. In June and July 2009, an anonymized questionnaire was sent via e‐mail, asking whether mothers of the above patients were screened for HCMV, and about the enteral feeding protocol for preterm infants <32W GA or <1500 g BW from HCMV‐seropositive mothers. Results: During the study period, 58.6% of the questionnaires (123/210) from Germany, 50% (13/26) from Austria and 50% (6/12) from Switzerland were returned, yielding a total of 6232 preterm infants for analysis. Formula was given to the mentioned preterm infants in 28.5% (35/123) of the German NUs but not in Austria or Switzerland. Untreated breast milk was given in 66.6% (4/6) of the Swiss, 14.6% (18/123) of the German and no Austrian NU. Long‐term pasteurized breast milk was given in 32.5% (40/123) of the German and 38.5% (5/13) of the Austrian NUs, but not in Switzerland. Short‐term pasteurized breast milk was given only in 5.7% (7/123) of German NUs. Freeze‐thawed breast milk was given in Germany (4.9%; 6/123), Austria (61.5%; 8/13) and Switzerland (16.7%; 1/6). Conclusion: Preterm infants <32W GA or <1500 g BW born to HCMV‐seropositive mothers are fed according to different regimes in German‐speaking countries. About 28.5% of the German VLBW‐infants receive formula, which is not recommended. 相似文献

Incidence of thrombocytopenia in infants born to mothers with idiopathic thrombocytopenic purpura 总被引:2,自引:0,他引:2

Abstract Neonatal thrombocytopenia related to maternal idiopathic thrombocytopenic purpura (ITP) is reportedly uncommon but may have severe complications. The present report reviews records of 15 infants born to mothers with ITP during a 10-year period, and the incidence of neonatal thrombocytopenia and the risk of hematological complications is examined. Severe thrombocytopenia (platelets < 50 000/μL) was seen in three infants despite successful therapy with high-dose gamma globulin prior to delivery, which elevated maternal platelet counts. Although the platelet counts of these three infants fell to < 10 000/μL, none had severe complications. Moreover, no infants required treatment such as adrenocorticosteroids, platelets transfusion, or high doses of gamma globulin. No maternal markers predicted the degree of neonatal thrombocytopenia. The risk of complications arising from neonatal thrombocytopenia is low, but careful observation is required for the thrombocytopenic newborn of ITP mothers even when the infant has no bleeding complications at delivery. 相似文献

Human milk is often inadequate nutritionally for preterm infants. We investigated the effect of adding a commercially prepared milk fortifier to human (maternal or bank) milk and measured changes in lower leg length velocity (LLLvel) using knemometry, weight gain and biochemical indices of nutrition. Babies were allocated to one of three feed groups, in a semi-randomized fashion, to receive human milk alone (group I), fortified human milk (group II) or a preterm formula (group III). The birthweights (median and R) and birth gestations (median and R) of the three groups were as follows: group I 1099 g (654-1248 g) and 28 wk (26-32 wk); group II 838 g (742-1340g) and 31 wk (28-36); group III 1136g (624-1552g) and 32 wk (27-36 wk). All babies who received fortified milk either showed significant (p = 0.0004) acceleration in LLLvel during the period studied, or maintained their pre-study period velocity. This increase in LLLvel was comparable to that achieved by a group of babies given a standard preterm infant formula (p < 0.001). By comparison, the control group's change in LLLvel was more modest (p = 0.04). Babies who received human milk with the fortifier added had the lowest serum levels of alkaline phosphatase at the end of the study period when compared to the other two groups. Other biochemical indices were similar in the three feed groups. No adverse clinical events were encountered which could be attributed to the use of the breast milk fortifier. 相似文献

Human milk is the preferred feeding for all infants, including premature and sick newborns, with rare exceptions. However, modern technology has produced alternative, "humanized formulae", which closely mimic the composition of human milk. The ingestion of human milk, "humanized formulae" or whole cow's milk has consequences for human nutrition. Gastroesophageal reflux, iron deficiency, calcium and sodium excesses or deficiencies may be influenced by the type and amount of milk fed to the infant. Likewise, neurological development and the likelihood of developing diabetes or cancer may also be influenced by early dietary practices. Until new information is available, we should continue to pattern formulae for older infants after breast milk, but with sufficient protein, calories, lipid and minerals to support optimal growth. 相似文献

Infants born small for gestational age (SGA) show some forms of developmental delay throughout paediatric age, and up to adolescence. The positive effect of breastfeeding on development, observed in most studies on healthy, term infants, seems to be further stressed in the group of SGA infants, particularly if breastfeeding is protracted. Besides the close maternal-infant contact of breastfeeding, the nutritional factors of human milk, above all long-chain polyunsaturated fatty acids, including docosahexaenoic acid, may at least partly account for the observed association.
Conclusion: SGA infants represent a high-risk group, not only for developmental delay, but also for long-term, unfavourable metabolic consequences. Breastfeeding and human milk quality together could help to prevent some of the neurological and metabolic sequelae of being born growth retarded. 相似文献
