Transient tachypnea of the newborn (TTN), respiratory distress syndrome (RDS), and persistent pulmonary hypertension of the newborn (PPHN) are the three most common disorders that cause respiratory distress after birth. An understanding of the pathophysiology of these disorders and the development of effective therapeutic strategies is required to control these conditions. Here, we review recent papers on the pathogenesis and treatment of neonatal respiratory disease.

목 적 : TTN은 대부분의 경우 출생 24-72시간 이내에 좋아지는 것으로 알려져 있으나 때로는 72시간 이상 빈호흡이 지속되며 심각한 저산소증과 호흡부전, 기흉 등의 합병증이나 사망에까지 이르기도 한다. 지금까지 이러한 지속성 TTN에 대한 연구가 드물어 이들에 대한 발생 위험인자와 임상경과를 알아보고자 본 연구를 시행하였다. 방 법 : 2001년 1월 1일부터 2007년 9월 30일까지 서울아산 병원에서 출생한 12,021명의 신생아 중 신생아 중환자실에 입원하여 TTN으로 진단받은 재태연령 $35^{+0}$주 이상의 신생아 107명을 대상으로 환아와 그 어머니의 의무기록을 후향적으로 검토, 분석하였다. 빈호흡에 대한 다른 기저 질환 없이 빈호흡이 생후 72시간 이상 지속되는 경우를 PTTN으로 정의하고 빈호흡이 출생 72시간 이전에 호전되는 경우를 STTN으로 구분하여 TTN의 위험인자와 임상경과를 비교하였다. 대조군은 같은 기간 동안 신생아실에 입원한 정상 신생아 126명을 무작위로 선택하여 비교하였다. 결 과 : 전체 TTN환아 107명 중 55명(51%)이 PTTN에 해당하였다. PTTN군에서 출생 6시간 이내 발생하는 끙끙거림(grunting)의 빈도, 분당 90회 이상의 빈호흡, 산소 치료농도 0.4 이상, 기흉, 보조적 호흡기 치료 등이 빈번하였고 출생 첫날 측정한 총 단백과 알부민, 체중 감소 비율이 STTN군에 비해 낮았다. PTTN의 발생과 가장 관련 있는 예측 위험 인자로는 출생 6시간 이내 발생한 끙끙거림, 최대 호흡수가 90회 이상, 산소 치료농도가 0.4 이상인 경우 등이었다. 결 론 : TTN 환아에서 출생 6시간 이내의 끙끙거림, 최대 호흡수 분당 90회 이상, $FiO_2$ 0.4 이상인 경우 등의 위험 인자가 있는 경우 더 나쁜 임상 경과를 보일 것으로 예측할 수 있을 것이다. PTTN의 발생을 낮추고 질환의 빈도와 증상을 줄일 수 있는 방법에 대한 더 많은 연구가 필요하다.

Background: This study was conducted to investigate the epidemiological features, clinical courses, and diagnoses of neonates who are transferred to neonatal intensive care unit of Yeungnam University Hospital due to tachypnea soon after birth. Methods: Based on medical records, we performed a retrospective study of neonatal intensive care unit admissions due to tachypnea from January 2010 to December 2013. Results: A total of 311 neonates were included in this study. The patient characteristics showed male predominance at 2.65:1. Among the 311 neonates with tachypnea, 127 (40.8%) neonates needed oxygen supply, and 54 (17.4%) neonates needed assisted mechanical ventilation. Transient tachypnea of the newborns (TTN) (158, 50.8%) showed the highest incidence, followed by pneumonia (63, 20.3%), extrapulmonary infection (37, 11.9%), respiratory distress syndrome (21, 6.8%), air leak (16, 5.1%), meconium aspiration syndrome (12, 3.9%), congenital heart disease (5, 1.6%), metabolic acidosis (3, 1%), primary pulmonary hypertension of newborns (2, 0.6%) and anemia (2, 0.6%). Conclusion: Although the neonates with tachypnea showed no other respiratory distress symptom, clinicians should be aware of the possibility of other pulmonary diseases as well as TTN and their extra-pulmonary causes. If tachypnea does not improve within a few hours, the clinician should consider further evaluation and management as soon as possible.

Neonatal diabetes mellitus can be categorized as transient, permanent, or syndromic, and approximately half of the cases are transient. We present a case involving a term newborn who showed overt progression of transient neonatal diabetes mellitus, with complete remission within 6 months. On the second day of life, the patient presented with tachypnea, hyperglycemia, and decreased serum levels of C-peptide and insulin. Continuous subcutaneous infusion of insulin and continuous glucose monitoring were well tolerated. The patient showed a normal growth pattern, with no hyperglycemic or hypoglycemic episodes at 6 months of age. As it is rare and often asymptomatic, hyperglycemia may be attributed to various factors, including intrauterine environment, perinatal stress, and diverse genetic background. Therefore, consistent blood glucose monitoring and prompt early insulin therapy are crucial for any term newborns with persistent hyperglycemia, to prevent further diabetic complications. Moreover, continuous subcutaneous insulin infusion and the utilization of continuous glucose monitoring devices are the most effective and practical management strategies.

Purpose: Respiratory morbidity is the most common problem among neonates admitted to neonatal intensive care units. Therefore, the aim of this study was to make a differential diagnosis between transient tachypnea of the newborn (TTN), respiratory distress syndrome (RDS), and pneumonia through comparison of clinical features and test results. Methods: This retrospective study was conducted in 86 infants with TTN, RDS, or pneumonia. These were infants who had respiratory distress, were born after ${\geq}34$ weeks of gestation, and transferred to the neonatal intensive care unit of Kosin University Gospel Hospital between June 1, 2011 and June 30, 2016. Results: The numbers (percentage) of infants with TTN, RDS, and pneumonia were 51 (59.3%), 20 (23.3%), and 15 (17.4%), respectively. Late-preterm and early-term newborns accounted for 65.1% of the infants. Tachypnea was observed in 74.4% of the neonates. The median age at admission was 4 hours (0 to 116) after birth. The infants with RDS had significantly lower birth weights, pH levels, base excess and oxygen saturation levels at admission, longer duration of total ventilator therapy, and hospital stay than those in the other two groups. The infants with pneumonia showed significantly high initial high-sensitivity C-reactive protein levels and significant chest radiographic findings. Conclusion: Early differential diagnosis for TTN, RDS, and pneumonia is challenging because they show similar respiratory symptoms at an early stage. Clinical features and test results can be used to determine the etiology of respiratory distress and early antibiotic treatment.

The purpose of this study is to understand the effects of simulation-based practice education on critical thinking disposition, clinical performance ability, and self-confidence. Using the method of one-group pretest-posttest experimental research, this study selected total 70 nursing students (3^rd year) as research subjects. The final research subjects were total 63 students excluding seven people with insufficient responses. From March to April 2023, total eight sessions of simulation practice education (4 hours per session) were conducted once a week. In the effects of the program, the critical thinking disposition, clinical performance ability, and self-confidence were measured. Using the SPSS Window Version 25.0, the critical thinking disposition, clinical performance ability, and self-confidence were analyzed through the mean, standard deviation, and paired t-test. In the results of this study, the critical thinking disposition (t=-10.61, p<.001), clinical performance ability (t=-3.06, p=.003), and self-confidence (t=-15.97, p<.001) were statistically significant. In the results of analyzing the correlations of clinical performance ability, and self-confidence after the simulation practice education, the learning satisfaction showed significantly positive correlation with immersion (r= .647, p<.001). The results of this study verified the improvement of critical thinking disposition, clinical performance ability, and self-confidence of nursing students after the simulation-based practice education. Thus, it would be necessary to develop the educational contents for various subjects, and also to expansively apply the simulation practice education.

Objective: To compare neonatal respiratory morbidity of twins according to birth order related to gestational age and mode of delivery. Methods: We performed the retrospective research of the medical records of 3,224 neonates (1,612 twin pairs) born in a single center from January 2011 to December 2015. Subjects were classified into four gestational age groups: very (<32 weeks), moderate (32-33 weeks), late (34-36 weeks) preterm, and term (${\geq}37weeks$) groups. We investigated clinical characteristics and respiratory morbidity according to birth order related to gestational age group and mode of delivery. Results: We found increased risk of respiratory morbidity in second-born twin than first-born twin (P=0.039). Second-born twin was associated with increased risk of respiratory distress syndrome (RDS) in late preterm group (odds ratio [OR] 2.8, 95% confidence interval [CI] 1.30-5.95), and transient tachypnea of newborn in term group (OR 1.4, 95% CI 1.03-1.81). In vaginal delivery mode, there was no difference of respiratory morbidity between first and second-born twin in each group, but in cases of Cesarean delivery, second-born twin was related with a greater risk of RDS in late preterm group (OR 2.3, 95% CI 1.07-5.09). Birth order and Cesarean section independently increased the risk of RDS (adjusted OR [aOR] 1.69, 95% CI 1.12-2.54; aOR 2.14, 95% CI 1.25-3.66, respectively). Conclusion: Second-born twin and Cesarean delivery are associated with increased risk of RDS, especially in late preterm twins.
