Populations in high infectious exposure countries are at low risk of some immune-mediated diseases such as Crohn's disease and allergy. This low risk is maintained upon immigration to an industrialized country, but the offspring of such immigrants have a higher immune-mediated disease risk than the indigenous population. We hypothesize that early life exposures in a developing country shape the maternal immune system, which could have implications for the offspring born in a developed country with a low infectious load. The aim of this study was to investigate if exposures in childhood (indicated by country of origin) and subsequent exposures influence immunologic characteristics relevant to stimulation of offspring. Breast milk components among 64 mothers resident in Sweden, 32 of whom immigrated from a developing country, were examined using the ELISA and Cytometric Bead Array methods. Immigrants from a developing country had statistically significantly higher levels of breast milk interleukin-6 (IL-6), IL-8 and transforming growth factor-β1. A larger number of previous pregnancies were associated with down-regulation of several substances, statistically significant for soluble CD14 and IL-8. The results suggest that maternal country of birth may influence adult immune characteristics, potentially relevant to disease risk in offspring. Such a mechanism may explain the higher immune-mediated disease risk among children of migrants from a developing to developed country. Older siblings may influence disease risk through the action of previous pregnancies on maternal immune characteristics. 相似文献

The neutrophil oxidative burst is a product of the regulated assembly of the multicomponent oxidase enzyme. Our aim was to compare the oxidative burst in term (n = 10) and preterm newborns <31 wk gestational age (n = 10) after stimulation with coagulase-negative staphylococci in vitro. Strains of Streptococcus epidermidis with different invasive and slime-producing properties, one strain of S. haemolyticus, and one strain of group B-streptococcus were investigated. A whole-blood flow cytometric assay using the oxidation of hydroethidine to ethidium bromide was used. The oxidative activity in unstimulated neutrophil granulocytes [polymorphonuclear leukocytes (PMNLs)] was similar in term and preterm newborns, but the preterm newborns showed a significantly lower capacity to up-regulate the oxidative burst intensity after bacterial stimulation (p = 0.004). In the term but not in the preterm group, the oxidative burst intensity after bacterial stimulation correlated with the baseline oxidative burst intensity. After bacterial stimulation, there was a trend toward a greater percentage of activated neutrophils in the term group than in the preterm group, but the difference was less pronounced than that in oxidative burst intensity. Significant differences in oxidative burst response to different bacterial strains were observed (p < 0.001), but the differences could not be correlated exclusively to invasive capacity or slime-producing properties. It is concluded that the baseline oxidative activity is similar in term and preterm PMNLs but that preterm PMNLs have a decreased capacity to increase the oxidative burst in response to bacterial stimulation. 相似文献

AIMS: The aims of this study were to compare the pain reducing effect of oral glucose with that of being breast-fed shortly before venipuncture in newborns, and also the pain score and crying time with parents' assessment. DESIGN: Randomised, controlled trial. SUBJECTS: 120 full term newborns undergoing venipuncture randomly assigned to on of four groups: I, Breast-fed and 1-ml placebo; II, Breast-fed and 1-ml 30% glucose; III, Fasting and 1-ml placebo; and IV, Fasting and 1-ml 30% glucose. OUTCOME MEASURES: Pain during venipuncture was measured with the Premature Infant Pain Profile (PIPP). Crying time was recorded. The parents assessed their babies' pain on a Visual Analogue Scale (VAS). RESULTS: The PIPP score was significantly lower in the infants receiving glucose, than in those not given glucose (p=0.004). There was no significant difference in PIPP score between the infants who were fed and the fasting infants. The PIPP score was lower in group II (median 7) than in group I (md 10). There was a similar difference between group IV (md 9) and group III (md 11). The median crying times during the first 3 min in groups I, II, III, and IV were 63, 18, 142 and 93 s, respectively. There was low agreement between the parents' assessment of pain and the PIPP score and crying time. CONCLUSION: Breast-feeding shortly before venipuncture has no major impact on the pain score but on crying time. The combination of oral glucose and breast-feeding shows the lowest pain score and significantly shorter duration of crying. 相似文献

AIM: To determine whether sepsis caused by coagulase-negative staphylococci (CoNS) is a risk factor for developing bronchopulmonary dysplasia (BPD) in premature newborns. METHODS: All newborns born at < or = 30 wk of gestation at Orebro University Hospital during 1994-2001 with clinical sepsis caused by CoNS (group A, n = 22) or by other bacteria (group B, n = 17) were included and compared with premature newborns without sepsis (group C, n = 53). Clinical sepsis was defined as a positive blood culture (monoculture) plus clinical symptoms and laboratory findings. BPD was defined as treatment with oxygen > 21% for at least 28 d. RESULTS: The incidence of BPD differed between the three groups, as follows: CoNS sepsis (A) 64%, other sepsis (B) 41% and control (C) 24%. The difference between the control group and the sepsis groups was highly significant (p = 0.006). In a univariate model the crude estimates of relative risk (RR) for occurrence of BPD increased with presence of sepsis and particularly with presence of sepsis with CoNS (A: RR 2.6, 95% CI 1.5-4.6, p = 0.001; B: RR 1.7, CI 0.8-3.5, p = 0.17). When regression was performed with two additional predictive variables in multivariate models including sepsis, gestational age and mechanical ventilation (group A: RR 1.5, CI 1.1-2.0, p = 0.004; group B: RR 0.9, CI 0.6-1.4, p = 0.67), the estimates were lower. CONCLUSION: The relative risk for BPD is significantly increased in premature newborns with sepsis caused by CoNS compared with those with sepsis caused by other bacteria and compared with premature newborns with no sepsis. 相似文献

BACKGROUND: The birth of a preterm infant has a long-term impact on both parents. Mothers report more stress and poor adjustment compared with fathers. Influencing factors, such as family situation and health status of the child, can support or weaken the coping ability of the parents. Studies on experiences of fathers are sparse. AIM: The aim of this research was to study how mothers and fathers of preterm infants describe their experiences of parenthood during the infant's first 18 months of life. METHODS: Seven consecutively selected sets of parents of preterm infants born at =34 weeks of gestation with no serious congenital defects were interviewed 1-2 weeks after the infant's birth and at 2, 6 and 18 months of age, and the findings were analysed using a phenomenological method. FINDINGS: Internalization of parenthood was described as a time-dependent process, with four syntheses of experiences - alienation, responsibility, confidence and familiarity. Within the syntheses, similarities in how mothers and fathers described their parental roles involved concern for the child, insecurity, adjustment and relationship with the child. Regarding differences, mothers experienced having more responsibility and control of the care and a need to be confirmed as a mother, while fathers described confidence in leaving the care to the staff and wanted to find a balance between work and family life. Important turning points in parenthood experiences often occurred when the infant could be removed from the incubator, discharged from the ward, and when the infant looked normal compared to full-term infants. CONCLUSIONS: The structure of the phenomenon of parenthood was formed by the integration of the syntheses of alienation, responsibility, confidence and familiarity. The structure seems to be based on the parents' expectations of the parental role, the infant's health condition and the health care environment. These interacting factors are influenced by cultural beliefs. 相似文献

Congenital myotonic dystrophy (CMD) is characterized by hypotonia, facies myopathica, feeding and respiratory problems, skeletal deformities and polyhydramniosis. It is an autosomal-dominant disorder transmitted via the mother. The diagnosis can as a role be confirmed by examining the mother, but can fail as she might be asymptomatic. During a nine year period, eight children were diagnosed as CMD which means an incidence of one case per approximately 3,500 live births. The diagnosis was confirmed in six of the mothers. The two floppy infants, where positive inheritance could not be proven, showed most of the signs and symptoms described in CMD. Four children died, two from respiratory insufficiency and two suddenly and unexpectedly. CMD may be one less common cause of sudden infant death syndrome (SIDS). The four children who survived displayed delayed psychomotor development. 相似文献

All cases of neonatal septicaemia during 1981-94 were studied at Örebro Medical Centre Hospital, Sweden. One hundred and thirty-two children fulfilled laboratory and clinical criteria for neonatal septicaemia and were included. Staphylococcus aureus ( n = 41), Group B streptococcus (GBS) ( n = 32) and coagulase-negative staphylococci (CoNS) ( n = 27) were the dominating aetiologies. The annual incidence of septicaemia increased significantly, from 2.3 cases during the first 7-year period to 3.3 per 1000 live births during 1988-94. This increase was caused by S. aureus and CoNS, which mainly affected premature children and had an onset more than 48 h after delivery. GBS, on the other hand, slightly decreased and affected full-term children within 48 h. The overall mortality was 11%. CoNS isolated during the latter 7-year period were more resistant to antibiotics than those isolated during 1981-87; resistance to methicillin increased from 14 to 45% and to gentamicin from 0 to 20%. These changes in aetiology and antibiotic susceptibility should be considered when selecting antibiotic treatment in neonatal septicaemia. 相似文献
