PURPOSE: The purpose of this study was to evaluate the effects of a communication course with lecture, small group activity and music therapy for nursing students, compared to a conventional lecture course. METHODS: The design of this study was a nonequivalent control group with a pre-post test. Data were collected by questionnaires from 166 nursing students from Y University, Seoul, Korea, with 92 in the experimental group and 74 in the control group. A 13 session program with lecture, small group activity and music therapy was given to the experimental group in 2008, while a conventional lecture course was given to the control group in 2007. The data were analyzed using descriptive statistics, and independent/paired t-tests. RESULTS: There were no significant differences in interpersonal communications or relationships change between the experimental and control group. We found that which area in interpersonal communication and relationships had a positive effect in each course. CONCLUSION: The results indicate a need to consider the characteristics of students and thoroughly prepare for operational difficulties in advance of effectively administering various instructional methods in communication courses for nursing students in the second year.

PURPOSE: To analyze and compare the clinical factors and neurodevelopmental outcomes compare early- and late-onset periventricular leukomalacia (PVL) in very low birth weight infants (VLBWI). METHODS: We performed a retrospective study involving 199 newborn infants weighing < 1,500 g admitted to the neonatal intensive care unit between March 2009 and December 2015. VLBWI with PVL were categorized into early- and late-onset PVL groups based on the time of diagnosis based on 28 days of age. We analyzed the clinical factors and neurodevelopmental outcomes between the groups. RESULTS: The incidence rate of PVL was 10.1% (16/158). The Apgar score at 1 minute and the mean duration of tocolytic therapy were associated with the development of PVL. The incidence rate of premature rupture of membranes (PROM) was significantly higher in the early-onset PVL group (P=0.041). No significant differences were observed in neurodevelopmental outcomes between the early- and late-onset PVL groups. CONCLUSION: Results suggest that a higher incidence of PROM was associated with clinical characteristics in the early-onset PVL group. No significant intergroup differences were observed in neurodevelopmental outcomes; however, the Bayley Scales of Infant Development-III scores were lower in the early-onset PVL group.

PURPOSE: This study aimed to investigate the prevalence of delayed thyroid dysfunction based on iodine disinfectant use and to analyze associated risk factors.METHODS: A retrospective study was conducted on late preterm infants admitted to the neonatal intensive care unit between January 2010 and June 2018, who underwent neonatal thyroid screening (NTS) and ≥2 thyroid function tests (TFTs). NTS was performed 3 days after birth, with at least two TFTs 1 week and 2 to 4 weeks after birth. To distinguish between normal and dysfunctional thyroid levels, we reviewed TFT results at 2 to 4 weeks and examined possible risk factors for the development of thyroid dysfunction.RESULTS: Of 295 late preterm infants, 262 were enrolled with a mean gestational age and birth weight of 34.8±0.7 weeks and 2,170±454 g, respectively. A total of 7.6% developed hyperthyrotropinemia at the age of 24.3±14.6 days (range, 12 to 69). The incidence of hyperthyrotropinemia during iodine use was approximately 12.6%, while that during discontinuation was 2.4% (P=0.002). Multivariate analysis revealed that small for gestational age (SGA), iodine disinfectant use, and abnormal NTS results were significant risk factors for delayed hyperthyrotropinemia (adjusted odds ratio [AOR]: 4.27, P=0.008; AOR: 8.24, P=0.003; and AOR: 7.80, P=0.002, respectively).CONCLUSION: Delayed hyperthyrotropinemia was prevalent in late preterm infants exposed to topical iodine and those identified as being SGA. Secondary TFTs should be considered 2 to 4 weeks after birth for this population at risk.

Purpose: We used the Bayley Scales of Infant and Toddler Development (BSID)-III to analyze the incidence and risk factors of developmental delay in very-low-birth-weight infants without severe brain lesions. We further examined the correlation between the cumulative dexamethasone dose and developmental assessment results. Methods: We retrospectively analyzed data of preterm infants (birth weight <1,500 g) admitted to our neonatal intensive care unit between January 2014 to December 2020. The BSID-III scores obtained between the corrected ages of 12 and 24 months and after 24 months were analyzed. Developmental delay was defined as a composite score of <85 for the cognition, language, and motor domains. Univariate and multivariate analyses of developmental delay risk factors and developmental changes from the first to second BSID-III were performed. Correlations between the accumulated dexamethasone dose used for bronchopulmonary dysplasia (BPD) and the first and second test scores were analyzed. Results: Seventy-one and thirty-six infants completed the first and second tests, respectively. In both tests, developmental delay was most commonly observed in the language domain (26.8%, 47.2%). In multivariate analysis, mild BPD was identified as a developmental delay risk factor (P<0.05), whereas prenatal steroid use reduced the developmental delay risk (P<0.05). All domain scores were lower in the second test than in the first test. The cognition and language domain scores in the second test decreased with increasing cumulative dexamethasone doses. Conclusion Very-low-birth-weight infants typically experience language delay, which can persist as they age.

Purpose: Since premature infants are sensitive to the changes in blood glucose levels and body temperature, maintaining these parameters is important to avoid the risk of infections. The authors implemented the Golden Hour protocol (GHP) that aims to close the final incubator within one hour of birth by implementing early treatment steps for premature infants after birth, such as maintaining body temperature, securing airway, and rapidly administering glucose fluid and prophylactic antibiotics by securing breathing and rapid blood vessels. This study investigated the effect of GHP application on the short- and long-term clinical outcomes. Methods: We retrospectively analyzed the medical records between 2017 and 2018 before GHP application and between 2019 and 2020 after GHP application in preterm infants aged 24 weeks or older and those aged less than 33 weeks who were admitted to the neonatal intensive care unit. Results: Overall, 117 GHP patients and 81 patients without GHP were compared and analyzed. Peripheral vascularization time and prophylactic antibiotic administration time were shortened in the GHP-treated group (P=0.007 and P=0.008). In the short-term results, the GHP-treated group showed reduced hypothermia upon arrival at the neonatal intensive care unit (P=0.002), and the blood glucose level at 1 hour of hospitalization was higher (P=0.012). Furthermore, the incidence of neonatal necrotizing enteritis decreased (P=0.043). As a long-term result, the incidence of BPD was reduced (P=0.004). Conclusion We confirmed that applying GHP improved short- and long-term clinical outcomes in premature infants aged <33 weeks age of gestation, and we expect to improve the treatment quality by actively using it for postnatal treatment.

Purpose: Syphilis infections are becoming more prevalent in the Republic of Korea, and inadequately treated syphilis can lead to congenital syphilis (CS) in newborns. This study aimed to analyze the clinical manifestations of syphilis in mothers and newborns and to make suggestions to improve disease prognosis. Methods: This single-center study was performed between August 2009 and August 2019 and included 29 newborns with CS. We retrospectively evaluated the clinical features, rapid plasma reagin (RPR) card test, fluorescent treponemal antibody absorption test (FTA-ABS), morbidity, and treatment regimen of all the syphilis-affected mothers and their newborns. Results: At the time of delivery, mean maternal age was 29.0±6.1 years old, and newborn gestational age was 38.0 weeks. In cases when syphilis was confirmed during the second and third trimesters of pregnancy, the newborn with CS had morbidity (p=0.004). The mean RPR titer was related to morbidity (p= 0.036). Positive results of FTA-ABS IgM (p<0.001) and pleocytosis in the cerebrospinal fluid (CSF) (p= 0.020) also increase morbidity. The most common symptoms were desquamation and skin rash, followed by hepatomegaly, neurodevelopmental disability, and bone abnormalities. The highest number of CS cases per 1,000 live births in this hospital was in 2014. Conclusion CS is a preventable and treatable disease if physicians detect symptoms and provide appropriate treatment through RPR examinations during every trimester. General practitioners should be widely trained on various aspects including early detection, formal treatment, and regular follow-up. Additionally, medical services should be provided for the entire childbearing population regardless of the socioeconomic status.

Esophageal atresia (EA) with proximal tracheoesophageal fistula (TEF; gross type B) is a rare defect. Although most patients have long-gap EA, there are still no established surgical guidelines. A premature male infant with symmetric intrauterine growth retardation (birth weight, 1,616 g) was born at 35 weeks and 5 days of gestation. The initial diagnosis was pure EA (gross type A) based on failure to pass an orogastric tube and the absence of stomach gas. A “feed and grow” approach was implemented, with gastrostomy performed on postnatal day 2. A fistula was detected during bronchoscopy for recurrent pneumonia; thus, we confirmed type B EA and performed TEF excision and cervical end esophagostomy. As the infant's stomach volume was insufficient for bolus feeding after reaching a body weight of 2.5 kg, continuous tube feeding was provided through a gastrojejunal tube. On the basis of these findings, esophageal reconstruction with gastric pull-up was performed on postnatal day 141 (infant weight, 4.7 kg), and he was discharged 21 days postoperatively. At 12 months after birth, there was no catch-up growth; however, he is currently receiving a baby food diet without any complications. In patients with EA, bronchoscopy is useful for confirming TEF, whereas for those with long-gap EA with a small stomach volume, esophageal reconstruction with gastric pull-up after continuous feeding through a gastrojejunal tube is worth considering.

Purpose: This study aimed to identify prognostic factors based on treatment outcomes for congenital diaphragmatic hernia (CDH) at a single-center and to identify factors that may improve these outcomes. Methods: Thirty-five neonates diagnosed with CDH between January 2011 and December 2021 were retrospectively analyzed. Pre- and postnatal factors were correlated and analyzed with postnatal clinical outcomes to determine the prognostic factors. Highest oxygenation index (OI) within 24 hours of birth was also calculated. Treatment strategy and outcome analysis of published literatures were also performed. Results: Overall survival rate of this cohort was 60%. Four patients were unable to undergo anesthesia and/or surgery. Three patients who commenced extracorporeal membrane oxygenation (ECMO) post-surgery were non-survivors. Compared to the survivor group, the non-survivor group had a significantly higher occurrence of pneumothorax on the first day, need for high-frequency ventilator and inhaled nitric oxide use, and high OI within the first 24 hours. The non-survivor group showed an early trend towards the surgery timing and a greater number of patch closures. Area under the receiver operating characteristic curve was 0.878 with a sensitivity of 76.2% and specificity of 92.9% at an OI cutoff value of 7.75. Conclusion OI within 24 hours is a valuable predictor of survival. It is expected that the application of ECMO based on OI monitoring may help improve the opportunity for surgical repair, as well as the prognosis of CDH patients.

Bone diseases such as osteoporosis and periodontitis are induced by excessive osteoclastic activity, which is closely associated with inflammation. Benzydamine (BA) has been used as a cytokine-suppressive or non-steroidal anti-inflammatory drug that inhibits the production of pro-inflammatory cytokines or prostaglandins. However, its role in osteoclast differentiation and function remains unknown. Here, we explored the role of BA in regulating osteoclast differentiation and elucidated the underlying mechanism. BA inhibited osteoclast differentiation and strongly suppressed interleukin-1 (IL-1) production. BA inhibited osteoclast formation and bone resorption when added to bone marrow-derived macrophages and differentiated osteoclasts, and the inhibitory effect was reversed by IL-1 treatment. The reporter assay and the inhibitor study of IL-1 transcription suggested that BA inhibited nuclear factor-B and activator protein-1 by regulating IB kinase, extracellular signal regulated kinase and P38, resulting in the down-regulation of IL-1 expression. BA also promoted osteoblast differentiation. Furthermore, BA protected lipopolysaccharide- and ovariectomy-induced bone loss in mice, suggesting therapeutic potential against inflammation-induced bone diseases and postmenopausal osteoporosis.
