Purpose: The purpose of this study was to investigate the effects of anxiety and smartphone dependency on sleep quality in pregnant women with preterm labor. Methods: The participants of this study were 111 pregnant women who were between 20 and 37 weeks of gestation and experienced preterm labor. The data were collected from October 1, 2018 to October 25, 2019. The collected data were analyzed using descriptive statistics (frequency, percentage, and standard deviation), as well as the t-test, Pearson correlation coefficients, and hierarchical multiple regression. Results: Significant negative correlations were found between anxiety and sleep quality and between smartphone dependency and sleep quality. Participants' history of preterm birth, pregnancy method, bowel movements, anxiety, and smartphone dependency significantly affected sleep quality, with an explanatory power of 18%. Conclusion: In order to improve the quality of sleep, which is an important health-related factor for pregnant women experiencing preterm labor, it will be necessary to identify a history of premature birth, pregnancies achieved using artificial reproductive technology, bowel problems, and smartphone dependency in advance and to provide nursing interventions accordingly.
This study was to develop a screening tool to identify the pregnant women who are required to have a concrete checkup or education about preterm birth. The items for the screening tool were drafted from literature review and the result of interviews with women who are hospitalized after preterm delivery based on the biopsychosocial framework. The validity and reliability of the items was performed after the content validity and the pilot survey. The screening tool for the risk of preterm birth in pregnant women was consisted of two parts. One was consisted of 9-items for the biomedical risks and another one was consisted of 17-items for the psycho-physical risks. The screening tool for the risk of preterm birth in pregnant women reveals valid and reliable. It could be applied to identify the pregnant women who have some risks of preterm birth.
Purpose: Preterm infants are at high risk for adverse neurodevelopmental outcomes. Magnetic resonance imaging (MRI) has been proposed as a means of predicting neurodevelopmental outcomes in this population. It is controversial whether diffuse excessive high signal intensity (DEHSI) represents damage to the white matter or delayed myelination in preterm infants. This study investigated MRI findings for predicting the severity of neurodevelopmental outcomes and assessing whether preterm infants with DEHSI near term-equivalent age have abnormal neurodevelopmental outcomes. Materials and Methods: Preterm infants (n = 64, gestational age at birth < 35 weeks) undergoing brain MRI near term-equivalent age and subsequent neurodevelopmental outcomes were evaluated between 18 and 24 months of age. The associations of MRI findings and the risk of severe cognitive delay, severe psychomotor delay, cerebral palsy (CP), and neurosensory impairment were analyzed. The associations of DEHSI with risks of severe cognitive delay, severe psychomotor delay, CP, and neurosensory impairment (hearing or visual impairment) were analyzed. Outcome data were evaluated by logistic regression and the Fisher's exact test. Results: There were significant associations between abnormal white matter findings and delayed mental development, delayed psychomotor development, neurosensory impairment, and presence of CP. The presence of DEHSI was not correlated with delayed neurodevelopmental outcomes or presence of CP. In multivariate logistic regression analyses, cystic encephalomalacia, punctate lesion, loss of white matter volume and ventricular dilation were significantly associated with CP. Conclusion: Abnormal MRI findings near term-equivalent age in preterm infants predict adverse neurodevelopmental outcomes. No significant association between DEHSI and adverse neurodevelopmental outcomes was demonstrated.
Purpose: Meconium-related ileus is common in preterm infants. Without proper management, it can cause necrotizing enterocolitis and perforation requiring emergent operation. This study was conducted to describe the efficacy and safety of ultrasound-guided Gastrografin enema at bedside for preterm infants with meconium-related ileus. Methods: Between March 2013 and December 2014, this study enrolled preterm infants with birth weight <1,500 g, who were diagnosed with meconium-related ileus requiring ultrasound-guided Gastrografin enema refractory to glycerin or warm saline enemas. Gastrografin was infused until it passed the ileocecal valve with ultrasound guidance at bedside. Results: A total of 13 preterm infants were enrolled. Gestational age and birth weight were 28.6 weeks (range, 23.9-34.3 weeks) and 893 g (range, 610-1,440 g), respectively. Gastrografin enema was performed around postnatal day 8 (range, day 3-11). The success rate was 84.6% (11 of 13 cases). Three of these 11 infants received a second procedure, which was successful. Among 2 unsuccessful cases, one failed to pass meconium while the other required surgery due to perforation. The time required to pass meconium was $2.8{\pm}1.5hours$ (range, 1-6 hours). The time until radiographic improvement was $2.8{\pm}3.4days$ (range, 1-14 days) after the procedure. Conclusion: Ultrasound-guided Gastrografin enema at bedside as a first-line treatment to relieve meconium-related ileus was effective and safe for very low birth weight infants. We could avoid unnecessary emergent operation in preterm infants who have high postoperative morbidity and mortality. This could also avoid transporting small preterm infants to fluoroscopy suite.
Background: This study investigates the relationship of socioeconomic status with adverse birth outcomes (low birth weight, preterm birth) and the relationship of socioeconomic status with infant mortality, using the birth cohort in Korea, 1995-2010. Methods: 8,648,035 births from National Statistics Offics, 1995-2010 were studied with respect to social variation in adverse birth outcomes and infant mortality in Korea. The effect of social inequality was examined against adverse birth outcomes and infant mortality using multivariate logistic regression after controlling for other covariates. Results: Social inequality were observed in adverse birth outcomes: low birth weight (LBW, 1,500-2,499 g), very LBW (1,000-1,499 g), and extremely LBW (500-999 g) as well as moderately preterm birth (PTB, 33-36 weeks), very PTB (28-32 weeks), extremely PTB (22-27 weeks), and infant mortality. The effect of social inequality was higher among moderately LBW (1,500-2,499 g) and PTB (33-36 weeks) than very or extremely LBW and PTB. Conclusion: The social inequality in adverse birth outcomes (low birth weight and preterm) and infant mortality existed and increased in Korea from 1995 to 2010. The effect of maternal education on adverse birth outcomes as well as infant mortality was apparent in the study results. Especially, social inequailiy in infant mortality was greater among the sub-normal births (low birth weight [1,500-2,499 g] or preterm birth [33-36 weeks]), which suggests, social interventions should aim at more among the subnormal births. This study suggest that tackling inequality in births as well as infant mortality should be focused on the social inequality itself.

Purpose: In this study, we aimed to review the clinical presentation of preterm infants with gastrointestinal perforations and compare the clinical features of gastric perforation with other intestinal perforations. Methods: The medical records of preterm neonates with pneumoperitoneum, admitted to the neonatal intensive care unit (NICU) between January 1994 and December 2013, were retrospectively reviewed. Results: Twenty-one preterm infants underwent exploratory laparotomy to investigate the cause of the pneumoperitoneum. The sample consisted of five patients (23.8%) with gastric perforation and 16 patients (76.2%) with intestinal perforation. No statistical differences were found in the birth history and other perinatal factors between the two groups. Underlying necrotizing enterocolitis, bilious vomiting, and paralytic ileus preceding the perforation were statistically more common in the intestinal perforation group. All preterm infants with gastric perforation survived to discharge; however, six preterm infants with intestinal perforation expired during treatment in the NICU. In the gastric perforation group, sudden pneumoperitoneum was the most common finding, and the mean age at diagnosis was $4.4{\pm}1.7days$ of life. The location and size of the perforations varied, and simple closure or partial gastrectomy was performed. Conclusion: Patients with gastric perforation did not have a common clinical finding preceding the perforation diagnosis. Although mortality in previous studies was high, all patients survived to discharge in the present study. When a preterm infant aged less than one week presents with sudden abdominal distension and pneumoperitoneum, gastric perforation should first be excluded. Prompt exploratory laparotomy will increase the survival rates of these infants.

Purpose: Frequent desaturation due to immature incoordination of suck-swallow-breathing in preterm infants can influence multiple organs such as the heart, lungs, and brain, which can then affect growth and development. Most notably in preterm infants, feeding desaturation may even affect pulmonary function during gavage feeding. Because respiratory muscle activities may reflect the work required during respiration, we evaluated the differences in these activities between full-term and preterm infants with feeding desaturation, and investigated the correlations with clinical variables. Methods: Nineteen preterm infants with feeding desaturation (group 1) and 19 age-matched full-term infants (group 2) were evaluated. Oromotor function was evaluated using video recording. The root-mean-square (RMS) envelope of the electromyography signal was calculated to quantify the activities of muscles involved in respiration. The differences in RMS between both groups and the correlation with clinical variables including gestational age (GA), birth weight (BW), and Apgar scores (AS) at 1 and 5 minutes after birth were evaluated. Results: The RMS values of the diaphragm (RMS-D) and rectus abdominis (RMS-R) were significantly greater in group 1 compared to group 2, and the 1- and 5-min AS were significantly lower in group 1 compared to group 2. RMS-D and RMS-R were inversely correlated with GA, BW, 1- and 5-min AS in all infants. Conclusion: This study showed that respiratory muscle activities were augmented during feeding in preterm infants compared to full-term infants. Additionally, respiratory muscle activities were inversely correlated with all clinical variables.

Purpose: We investigated the vitamin D status of preterm infants to determine the incidence of vitamin D deficiency. Methods: A total of 278 preterm infants delivered at Kyungpook National University Hospital between January 2013 and May 2015 were enrolled. The serum concentrations of calcium, phosphorous, alkaline phosphatase, and 25-hydroxyvitamin D (25-OHD) were measured at birth. We collected maternal and neonatal data such as maternal gestational diabetes, premature rupture of membranes, maternal preeclampsia, birth date, gestational age, and birth weight. Results: Mean gestational age was $33^{+5}{\pm}2^{+2}$ weeks of gestation and mean 25-OHD concentrations were $10.7{\pm}6.4ng/mL$. The incidence of vitamin D deficiency was 91.7%, and 51.1% of preterm infants were classified as having severe vitamin D deficiency (25-OHD<10 ng/mL). The serum 25-OHD concentrations did not correlate with gestational age. There were no significant differences in serum 25-OHD concentrations or incidence of severe vitamin D deficiency among early, moderate, and late preterm infants. The risk of severe vitamin D deficiency in twin preterm infants was significantly higher than that in singletons (odds ratio, 1.993; 95% confidence interval [CI], 1.137-3.494, P=0.016). In the fall, the incidence of severe vitamin D deficiency decreased 0.46 times compared to that in winter (95% CI, 0.227-0.901; P=0.024). Conclusion: Most of preterm infants (98.9%) had vitamin D insufficiency and half of them were severely vitamin D deficient. Younger gestational age did not increase the risk of vitamin D deficiency, but gestational number was associated with severe vitamin D deficiency.
The purpose of this study is to provide basic data for preventing preterm delivery in the aspects of blood pressure and hematic parameters. The blood pressure, hematic parameters, relationship between hematic parameters and nutritional intakes and pregnancy outcomes were compared between a preterm delivery group and a normal term delivery group. The results obtained are summarized as follows. Diastolic blood pressure was statistically higher in the preterm delivery group. White blood cells (p < 0.005) and alanine amino transferase (p < 0.05) of 3rd trimester in pregnancy were statistically higher in the preterm delivery group. Alkaline phosphatase (p < 0.0001) and lactate dehydrogenase (p < 0.05) were statistically lower in the preterm delivery group. Inverse relationships between niacin, vitamin B6 and zinc intakes and bilirubin (p < 0.05) were shown. Vitamin A intakes (p < 0.05) were significantly negatively correlated with blood protein, but zinc intakes (p < 0.05) were significantly positively correlated with blood protein. Vitamin B6 intakes (p < 0.05) were significantly negatively correlated with blood albumin. Calcium intakes (p < 0.005) and iron intakes (p < 0.05) were significantly positively correlated with blood lactate dehydrogenase. Also, vitamin A intakes (p < 0.05) were significantly positively correlated with blood glucose. Normal spontaneous vaginal delivery (p < 0.005) was statistically lower in the preterm delivery group. Birth weight (p < 0.0001) and birth length (p < 0.005) of the neonates were all statistically lower in the preterm delivery group.

Objectives: We aimed to compare preterm, neurodevelopmentally disordered and healthy full-term children. Methods: We enrolled 47 children who were born preterm, 40 neurodevelopmentally disordered children, and 80 healthy children as control participants, in order to assess the cognitive functioning and the risk of behavioral problems at the age of 5. Children were assessed using the Korean Wechsler Preschool and Primary Scale of Intelligence-4th edition (K-WPPSI-IV), the Child Behavior Checklist (CBCL), and the Temperament and Character Inventory (TCI). Results: The mean K-WPPSI-IV score of the preterm group was $87.19{\pm}17.36$, which was significantly higher than that of the neurodevelopmental disorder group ($69.98{\pm}28.63$; p<0.001) but lower than that of the control group ($107.74{\pm}14.21$; p<0.001). The cumulative CBCL scores of the preterm children were not significantly different from those of the control group. Additionally, the TCI scores for reward dependence of the preterm children were higher than those of the control group. Conclusion: The cognitive performance of preterm infants was lower than that of healthy full-term infants at the age of 5, and there was an association between slower growth and decreased cognitive ability.
