Although outcomes of neonatal cardiac surgery have dramatically improved in the last two decades, low body weight still constitutes an important risk factor for morbidity and mortality. In particular, cardiac surgery in neonateswith very low birth weight (${\leq}$1.5 kg) is carried out with greater risk because most organ systems are immature. We report here on a successful case of early one-stage total repair of coarctation of the aorta and a ventricular septal defect in a 1,480 gram neonate.

Purpose: The starting time for probiotic supplementation in preterm infants after birth varies widely. This study aimed to investigate the optimal time for initiating probiotics to reduce adverse outcomes in preterm or very low birth weight (VLBW) infants. Methods: Medical records of preterm infants born at a gestational age (GA) of <32 weeks or VLBW infants in 2011-2020 were reviewed respectively. The infants who received Saccharomyces boulardii probiotics within 7 days of birth were grouped into an early introduction (EI) group, and those who received supplemented probiotics after 7 days of birth were part of the late introduction (LI) group. Clinical characteristics were compared between the two groups and analyzed statistically. Results: A total of 370 infants were included. The mean GA (29.1 weeks vs. 31.2 weeks, p<0.001) and birth weight (1,235.9 g vs. 1491.4 g, p<0.001) were lower in the LI group (n=223) than in the EI group. The multivariate analysis indicated that factors affecting the LI of probiotics were GA at birth (odds ratio [OR], 1.52; p<0.001) and the enteral nutrition start day (OR, 1.47; p<0.001). The late probiotic introduction was associated with a risk of late-onset sepsis (OR, 2.85; p=0.020), delayed full enteral nutrition (OR, 5.44; p<0.001), and extrauterine growth restriction (OR, 1.67; p=0.033) on multivariate analyses after adjusting for GA. Conclusion: Early supplementation of probiotics within a week after birth may reduce adverse outcomes among preterm or VLBW infants.

Objectives : To evaluate the association between working conditions and adverse pregnancy outcomes in Korea. Methods : We obtained data on health history, lifestyle, housework and Working conditions, such as shift work, hours standing, working time, job demand, lifting at work and at home, between August and September 2000, from self-reported questionnaires. A group of 344, occupationally active, pregnant women from 51 industries were studied. Of the women studied, 328 women were further interviewed by telephone between November 2000 and September 2001. Result : Compared with daytime work, shift work increased the risk for preform birth (an adjusted risk ratio of 2.74, 95% CI=1.02-2.62) and low birth weight (an adjusted risk ratio of 2.74,95% CI=1.02-2.02). A significantly increased risk was found for prolonged standing, with an adjusted risk ratio of preform births of 6.80 (95% CI=2.01-23.0). There were no significant differences in the incidence of spontaneous abortion between the occupational working conditions, with the enception of a previous history of spontaneous abortion. Conclusion : These findings suggest that maternal working conditions, such as shift work and prolonged standing, contribute significantly to preterm birth and low birth weight.

Forty-four Javanese thin-tail ewes were used to study the effect of superovulation prior to mating and of ration quality on lamb birth weight at parturition. Twenty-two ewes weaning at least one lamb were used to measure lamb preweaning growth. Prior to mating, the experimental ewes were injected twice with prostaglandin, with an 11 d interval between injections to synchronize the estrous cycle. At the last prostaglandin injection, 24 ewes were also injected with 700 IU of pregnant mare serum gonadotropin (PMSG) to stimulate superovulation and the remainder were injected with saline as control. During pregnancy and lactation, the experimental ewes were fed either on a low (12% CP and 65% TDN) or a high (15% CP and 75% TDN) quality ration. During lactation, the milk was collected twice a day and was refed to the lambs by bottle feeding immediately after collection. Superovulation or ration quality as a main factor did not significantly affect lamb birth weight. Litter size significantly affected lamb birth weight (p<0.05), and there was an interaction of superovulation and litter size. Nonsuperovulated ewes giving birth to multiple lambs had significantly lower average lamb birth weight (1.34 kg) as compared to those giving birth to a single lamb (1.97 kg) (p<0.05). However, superovulated ewes giving birth to multiple lambs had no significant difference in average lamb birth weight (1.68 kg) as compared to those giving birth to a single lamb (1.91 kg) (p>0.05). Superovulation of ewes prior to mating resulted in a significant improvement in lamb birth weight in the multiple litter size, without significant effect on average preweaning daily gain (p=0.07). Superovulation had a promising use in improving animal production through improvement of prenatal growth during pregnancy and milk production during lactation.

출생시 체중변화의 양상과 산모의 연령 및 출산순위와의 관계를 알아보기 위하여 1977년 1월부터 1986년 12월까지 부산시내 1개 종합병원에서 총 14,346건의 분만 가운데 20주이후에 출생한 단태아 13,634명을 대상으로 산실의 분만대장에서 신생아의 출생순위분포, 산모의 연령분포, 신생아의 체중분포와 평균체중, 산모의 연령과 출산순위에 따른 저 체중아와 과체중아의 출생을, 유산경험율과 사산율을 조사하였다. 신생아의 평균체중은 1979년에는 남아 3074gm, 여아 2985gm에서 1986년에는 남아 3266gm, 여아 3210gm 으로 증가하였고, 저체중아의 발생율은 1977년 7.2%에서 점차 증가하여 1980년에는 10.4%였으나 그후 점점 감소하여 1986년에는 6.5%였다. 과체중아의 발생율은 2,9%에서 4.6%사이로 평균 3.9%였으며 특별한 변화 양상은 볼 수 없었다. 유산을 경험 한 산모의 비율은 1979년에 51.6%에서 1986년에는 45.1%로 감소하였고, 사산율도 1977년에는 2.6%에서 1986년에는 1.5%로 감소했다. 이와같은 변화에는 가족계획 실천율의 증가와 결혼연령의 상승으로 $25{\sim}34$세사이 산모의 1과 2순위 출생아가 차지하는 비율이 증가한 것이 크게 영향을 미친 것으로 생각되며, 과체중아의 비율은 늘지 않고 오히려 저체중아의 출생율은 감소되어 전체적으로 신생아의 건강이 향상되고 있는 것으로 나타났다.

Purpose: The aim of this study is to examine the tolerability and effect of early high-dose amino acid administration in extremely low birth weight infants (ELBWIs). Methods: This retrospective cohort study included ELBWI (birth weight <1,000 g, n=142). Biochemical, nutritional, and neurodevelopmental data were compared between infants who received conventional low amino acid (LAA; 1.5 g/kg/day) and those who received high amino acid (HAA; 3 g/kg/day) within the first 48 hours after birth. Neurodevelopmental data included weight, height, and head circumference at discharge, 12 to 14 and 18 to 24 months of corrected age and the Korean Bayley Scale of Infant Development II (K-BSID-II) score at 18 to 24 months of corrected age. Results: The HAA group demonstrated higher peak plasma albumin ($3.0{\pm}0.4$ vs. $3.2{\pm}0.5$, P<0.05) and lower serum creatinine ($1.7{\pm}0.9$ vs. $1.4{\pm}0.8$, P<0.05) during the first 14 days than the LAA group. Full enteral feeding was achieved significantly earlier in infants in the HAA group than in infants in the LAA group ($46.2{\pm}23.0days$ vs. $34.3{\pm}21days$, P<0.01). There was no difference between the two groups in the z score changes in all growth indicators from birth to discharge and at 12 to 14 and 18 to 24 months of corrected age, as well as in the K-BSID-II score at 18 to 24 months of corrected age. Conclusion: Aggressive administration of amino acids during the first 2 days of life in ELBWI was well tolerated and correlated with earlier full enteral feeding, but did not improve growth and neurodevelopment.

Purpose: This paper reports the results of a hospital centered follow-up program on parenting stress, parenting efficacy and coping for mothers with very low birth weight (VLBW) infants. Methods: The follow-up program consisted of home visiting by an expert group and self-help program for 1 year. A non-equivalent control group pre-post quasi-experimental design was used. Participants were 70 mothers with low birth weight infants and were assigned to one of two groups, an experimental groups (n=28), which received the family support program; and a control group (n=27), which received the usual discharge education. Data were analyzed using ${\chi}^2$-test, t-test, and ANCOVA with IBM SPSS statistics 20.0. Results: Mothers' parenting stress (F=5.66, p=.004) was significantly decreased in the experimental group. There were also significant increases in parenting efficacy (F=13.05, p<.001) and coping (F=8.91, p=.002) in the experimental group. Conclusion: The study findings suggest that a follow-up program for mothers with VLBW infants is an effective intervention to decrease mothers' parenting stress and to enhance parenting efficacy and coping.

The purpose of this study is to develop a system dynamics model for growth prediction of low birth weight infants(LBWIs) based on nutrition. This growth prediction model consists of 9 modules; body weight, height, carbohydrate, protein, lipid, micronutrient, water, activity and energy module. The results of the model simulation match well with the percentiles of weights and heights of the Korean infants, also with the growth records of 55 LBWIs, under 37 weeks of gestational age, whose weights are appropriate for their gestational age. This model can be used to understand the current growth mode of LBWIs, predict the future growth of LBWIs, and be utilized as a tool for controlling the nutrient intake for the optimal growth of LBWIs in actual practice.
