LBW Infants (lbw + infant)
Selected AbstractsPregnancy outcome in congenital dyserythropoietic anemia type IEUROPEAN JOURNAL OF HAEMATOLOGY, Issue 4 2008Hanna Shalev Abstract Objectives:, Congenital dyserythropoietic anemia type I (CDA I) is a rare inherited disease characterized by moderate to severe macrocytic anemia and abnormal erythroid precursors with nuclear chromatin bridges and spongy heterochromatin. Moderate to severe maternal anemia is a recognized independent risk factor for low birth weight (LBW) and complicated delivery. The aim of the study was to review the outcome of pregnancies in women with CDA I. Methods:, The clinical and laboratory records of 28 spontaneous pregnancies in six Bedouin women with CDA I were reviewed. The results were compared with findings from a retrospective review of a large population-based registry including all pregnancies in Bedouin women during the same 15-yr period. Results:, Eighteen pregnancies in women with CDA I (64%) were complicated. One pregnancy was aborted spontaneously in the first trimester and one resulted in a non-viable fetus (stillborn at 26 wk). Cesarean section (CS) was performed in 10 pregnancies (36%). Eleven of the 26 newborns (42%) had a LBW: six were born prematurely and five were small for gestational age. The odds ratio for CS in women with CDA I compared with healthy Bedouin women was 4.5 [95% confidence interval (CI) 1.2,10.3], and for a LBW infant, 5.5 (95% CI 2.4,12.3). Careful follow-up was associated with significantly better fetal outcome (P = 0.05). Conclusions:, Pregnancies in women with CDA I are at high risk for delivery-related and outcome complications. To improve fetal outcome, women with CDA I should be carefully monitored during pregnancy. [source] Marriage still protects pregnancyBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 10 2005Kaisa Raatikainen Objective To assess the risk factors and outcome of pregnancy outside marriage in the 1990s, in conditions of a high percentage of extramarital pregnancies and high standard maternity care, used by the entire pregnant population. Design Hospital-based cohort study. Setting A university-teaching hospital in Finland. Population The 25,373 singleton pregnancies of known marital and cohabiting status. Methods Odds ratios (ORs) with 95% confidence intervals were calculated to estimate the effect of extramarital childbearing on pregnancy outcome. Multiple logistic regression analyses were conducted to control for confounding maternal risk factors. Main outcome measures Small-for-gestational age (SGA) infants, preterm birth (less than 37 completed weeks), low birthweight (LBW; under 2500 g). Results Of the study population, 67.5% were married and 32.5% were unmarried; 24.2% of all mothers were cohabiting. Unmarried status was strongly associated with social disadvantage and particular risk factors, specifically unemployment, smoking and previous pregnancy terminations, which in turn had an impact on obstetric outcome. There were significantly more SGA infants among unmarried mothers (P < 0.001), with an absolute difference of 45%; more preterm deliveries (P= 0.001), with an absolute difference of 17.5%; and more LBW infants (P < 0.001), with an absolute difference of 26%. The differences in adverse pregnancy outcomes between study groups (i) all unmarried women, (ii) cohabiting women and (iii) single women, remained significant after multivariate analysis at adjusted ORs of 1.11, 1.11 and 1.07 for SGA, 1.17, 1.15 and 1.21 for LBW and 1.15, 1.15 and 1.29 for the preterm births, respectively. Conclusion Even in the 1990s when cohabitation was already common, pregnancy outside marriage was associated with an overall 20% increase of adverse outcomes, and free maternity care did not overcome the difference. [source] Earlier versus later continuous Kangaroo Mother Care (KMC) for stable low-birth-weight infants: a randomized controlled trialACTA PAEDIATRICA, Issue 6 2010S Nagai Abstract Aim:, The aim of this study was to examine the effectiveness of earlier continuous Kangaroo Mother Care (KMC) for relatively stable low-birth-weight (LBW) infants in a resource-limited country. Methods:, A randomized controlled trial was performed in LBW infants at a referral hospital in Madagascar. Earlier continuous KMC (intervention) was begun as soon as possible, within 24 h postbirth, and later continuous KMC (control: conventional care) was begun after complete stabilization (generally after 24 h postbirth). Main outcome measure was mortality during the first 28 days postbirth. This trial was registered with ClinicalTrials.gov, NCT00531492. Results:, A total of 73 infants (intervention 37, control 36) were included. Earlier continuous KMC had higher but no statistically different mortality in the first 28 days postbirth (1 vs. 2; risk ratio, 1.95; 95% CIs, 0.18,20.53; p = 1.00). There were no differences in incidence of morbidities. Body weight loss from birth to 24 h postbirth was significantly less in earlier KMC infants compared with later KMC infants. (,34.81 g vs. ,73.97 g; mean difference, 39.16 g; 95% CIs, 10.30,68.03; p = 0.01; adjusted p = 0.02). Adverse events and duration of hospitalization were not different between the two groups. Conclusions:, Further evaluations of earlier continuous KMC including measurement of KMC dose, are needed in resource-limited countries. [source] Interactions among peripheral perfusion, cardiac activity, oxygen saturation, thermal profile and body position in growing low birth weight infantsACTA PAEDIATRICA, Issue 1 2010R Sahni Abstract Aims:, To investigate the correlation between the ,perfusion index' (PI) and other commonly used estimates of cutaneous blood flow [heart rate (HR), surface temperatures (ST) and central-to-peripheral thermal gradients (C-P grad)] and to use this new non-invasive tool to compare differences between prone and supine sleep position in low birth weight (LBW) infants. Methods:, Six-hour continuous recordings of pulse oximetry, cardiac activity and absolute ST from three sites (flank, forearm and leg), along with minute-to-minute assessment of behavioural states were performed in 31 LBW infants. Infants were randomly assigned to the prone or supine position for the first 3 h and then reversed for the second 3 h. PI data were correlated with HR and C-P grad, and compared across sleep positions during quiet sleep (QS) and active sleep (AS). Results:, Perfusion index correlated significantly with HR (r2 = 0.40) and flank-to-forearm thermal gradient (r2 = 0.28). In the prone position during QS, infants exhibited higher PI (3.7 ± 0.9 vs. 3.1 ± 0.7), HR (158.4 ± 8.9 vs. 154.1 ± 8.8 bpm), SpO2 (95.8 ± 2.6 vs. 95.2 ± 2.6%), flank (36.7 ± 0.4 vs. 36.5 ± 0.4°C), forearm (36.1 ± 0.6 vs. 35.5 ± 0.4°C) and leg (35.4 ± 0.7 vs. 34.7 ± 0.7°C) temperatures and narrower flank-to-forearm (0.6 ± 0.4 vs. 0.9 ± 0.3°C) and flank-to-leg (1.3 ± 0.6 vs. 1.8 ± 0.7°C) gradients, compared to those of the supine position. Similar differences were observed during AS. Conclusion:, Perfusion index is a good non-invasive estimate of tissue perfusion. Prone sleeping position is associated with a higher PI, possibly reflecting thermoregulatory adjustments in cardiovascular control. The effects of these position-related changes may have important implications for the increased risk for sudden infant death syndrome in prone position. [source] Trends in the prevalence of low birth weight in Okinawa, Japan: a public health perspectiveACTA PAEDIATRICA, Issue 2 2009T Hokama Abstract Aim: To review the trends in low birth weight (LBW) in Japan and Okinawa and to discuss the public health implications of the trend. Methods: The statistical records of Japan and the Okinawa prefecture were reviewed to observe secular trends of LBW incidence rate and other health indicators. Literature researches were undertaken of English and Japanese language publications to complete the review. Results: The LBW rate in Japan declined until the 1970s, reaching a low point for the whole country in 1978,1979 when it was 5.2% (7.2% in Okinawa). In Okinawa the proportion of LBW declined from 8.1% in 1973 to 7.2 in 1978. Since 1980 the LBW rate has steadily increased to its current level of 9.3% in Japan and 10.9% in Okinawa. During this period, the prematurity rate has not increased and other indicators of child health have continued to improve. Conclusion: Japan is unique among developed countries in that the LBW rate has almost doubled in the past three decades and the rate in Okinawa is 20% greater than the mainland. The health costs of this trend include the neonatal care of LBW infants and the increased risk of chronic disease in later life. [source] Postnatal peer counselling on exclusive breastfeeding of low-birthweight infants: A randomized, controlled trialACTA PAEDIATRICA, Issue 8 2005Grace V Agrasada Abstract Aim: Exclusive breastfeeding increases survival and optimizes growth of low-birthweight (LBW) infants. If supported, mothers can overcome the unique difficulties associated with breastfeeding from birth to 6 mo. We tested the efficacy of postnatal peer counselling among first-time mothers that aimed to increase exclusive breastfeeding of term LBW infants. Methods: In a Manila hospital, 204 mothers were randomized into three groups. Two intervention groups receiving home-based counselling visits, one by counsellors trained in breastfeeding counselling (n=68), the other by counsellors trained in general childcare (n=67), were compared with a control group of mothers (n=69) who did not receive counselling. Results: Eighty-eight per cent of the participating pairs completed the trial. At 6 mo, 44% of the breastfeeding counselled mothers, 7% childcare-counselled mothers and none of the mothers in the control group were exclusively breastfeeding. More mothers in the breastfeeding counselled group than in the other groups were still breastfeeding at 6 mo. Twenty-four infants who were exclusively breastfed for 6 mo did not have any diarrhoea. All groups had improved mean weight-for-age Z-scores at 6 mo. Conclusion: This study has provided fundamental evidence of successful intervention to achieve 6 mo of exclusive breastfeeding among term LBW infants. By improving health outcomes, enhanced breastfeeding offers a distinct possibility of disrupting the intergenerational cycle of undernourished women giving birth to LBW infants. [source] Postnatal and postprandial changes in plasma concentrations of glicentin in term and preterm infantsACTA PAEDIATRICA, Issue 10 2003R Tadokoro Aim: To examined the changes in basal plasma concentrations of glicentin in developing children and the postnatal and postprandial changes in plasma glicentin levels in infants. Methods: Glicentin, an active component of enteroglucagon, is considered to have a significant trophic action on the intestinal mucosa. Fasting plasma concentrations of glicentin in healthy children and in term and preterm infants were measured before and 30 min after feeding during the first 14 d of life. Results: Plasma basal concentrations of glicentin in children under 1 y of age were significantly higher than those in children aged 1 to 15 y. Plasma basal concentrations of glicentin at 5 or 6 d (2496 and 2190 pg/ml) and at 14 d (2987 and 2817 pg/ml) after birth were significantly higher than those at 1 or 2 d (1098 and 1240 pg/ml) after birth in normal birthweight (NBW) and low-birthweight (LBW) infants. There was no significant difference in the glicentin level between infants at 1 or 2 d (1864 pg/ml) and at 5 or 6 d (1910 pg/ml) after birth in very-low birthweight (VLBW) infants, but the levels at 14 d (3310 pg/ml) after birth were significantly higher than either of those levels. Plasma glicentin concentrations after feeding were significantly higher than those before feeding at 1 or 2 d and at 5 or 6 d after birth in NBW and LBW infants, but a significant increase in the plasma glicentin level after feeding was first observed at 14 d after birth in VLBW infants. There were no significant differences in the basal plasma (2401 and 2718 pg/ml) and postprandial (3007 and 3912 pg/ml) glicentin levels between breastfed and formula-fed infants. Conclusion: The results of the study suggest that glicentin may play an important role in intestinal mucosal growth in the early period of life, although its role in VLBW infants should be further investigated. [source] Late-onset neutropenia in very low birthweight infantsACTA PAEDIATRICA, Issue 2002G Chirico Aim: To evaluate the incidence and duration of late-onset neutropenia (defined as an absolute neutrophil count (ANC) <1500 mm,3 at a postnatal age of >3 wk) in a population of infants with birthweight <2000 g, and to determine whether copper deficiency, a possible cause of both anemia and neutropenia, may be associated with this complication. Methods: Complete blood cell count and differential were assessed in 247 low (LBW) and very low birthweight (VLBW) infants who were discharged after 3 wk of life. In neutropenic infants plasma copper and ceruloplasmin levels were also measured. Results: Late-onset neutropenia was detected in 11 out of 147 VLBW infants (7.5%) and in 7 out of 127 LBW infants (5.5%). A neutrophil count of <1000 mm,3 was observed in 14 infants (5.1%). A significantly lower gestational age was found in neutropenic infants compared with non-neutropenic infants. In neutropenic infants ANCs were significantly correlated with hemoglobin and hematocrit. In addition, a significant negative correlation was found between neutrophil and reticulocyte counts. Plasma copper concentration was significantly correlated with birthweight. Oral copper sulfate was administered to infants with plasma copper concentration <50 ,g dl,1, and did not seem to affect ANC, hemoglobin, hematocrit or reticulocyte counts. Conclusion: Late-onset neutropenia appears to be a benign condition that is not associated with any particular complication and does not require specific treatment. Reference ranges after the early neonatal period and during the first few months of life in LBW and VLBW infants should probably be set at lower values. [source] The association between maternal periodontitis and low birth weight infants among Malay womenCOMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 4 2008Norkhafizah Saddki Abstract,,, Objectives:, Maternal periodontitis has been suggested as one of the risk factors for low birth weight (LBW) infants. The objective of this study was to determine the association between maternal periodontitis and LBW infants among Malay women. Methods:, Screening periodontal examinations were carried out on all eligible Malay pregnant women in the second trimester of pregnancy attending two randomly selected community maternal and child health clinics in Kota Bharu, Kelantan. Patients with four or more sites with pocket depth 4 mm or higher, and clinical attachment loss 3 mm or higher at the same site with presence of bleeding on probing were diagnosed as having periodontitis in this study. Using this definition, systematic random sampling was utilized for selection of 250 subjects for each exposed and non-exposed group. Of 500 subjects enrolled in the study, 28 (5.6%) were either dropped or lost to follow-up. Of the remaining 472 subjects, 232 with periodontitis were in the exposed group and 240 with healthy periodontium were in the nonexposed group. Results:, The incidence of LBW was 14.2% (95% CI: 9.70,18.75) in women with periodontitis, and 3.3% (95% CI: 1.05,5.62) in women without periodontitis. The relative risk of having LBW infants was 4.27 times higher for women with periodontitis compared with those without periodontitis (95% CI: 2.01,9.04). After adjustment for potential confounders using multiple logistic regression analysis, significant association was found between maternal periodontitis and LBW (OR = 3.84; 95% CI: 1.34,11.05). Conclusion:, The results of this study provide additional evidence that pregnant women with periodontitis are at a significantly higher risk of delivering LBW infants. [source] | ||||||||||
