研究室紹介
Professor Young Hwa Jung's research lab specializes in neonatal intensive care, focusing on improving outcomes for preterm infants through innovative respiratory support strategies, immunomodulatory interventions, and data-driven clinical prediction models. The lab investigates non-invasive ventilation techniques such as neurally adjusted ventilatory assist (NAVA) and pressure support to enhance patient-ventilator synchrony and facilitate weaning. It also explores the immunologic benefits of oropharyngeal colostrum administration and develops machine learning-based models using noninvasive vital signs to predict neonatal sepsis and severe bronchopulmonary dysplasia. Additionally, the lab emphasizes multidisciplinary nutritional support to optimize growth and development in extremely low birth weight infants.

15OBJECTIVE: To determine the immunologic effects of oropharyngeal colostrum administration in extremely premature infants. METHODS: We conducted a double-blind, randomized, placebo-controlled trial involving 48 preterm infants born before 28 weeks' gestation. Subjects received 0.2 mL of their mother's colostrum or sterile water via oropharyngeal route every 3 hours for 3 days beginning at 48 to 96 hours of life. To measure concentrations of secretory immunoglobulin A, lactoferrin, and several imm
OBJECTIVE: To compare non-invasive ventilation neurally adjusted ventilatory assist (NIV-NAVA) and non-invasive pressure support (NIV-PS) in preterm infants on patient-ventilator synchrony. DESIGN: A randomised phase II crossover trial. SETTING: Neonatal intensive care units of two tertiary university hospitals in Korea. PATIENTS: Preterm infants born <32 weeks. INTERVENTION: NIV-NAVA and NIV-PS were applied in random order after ventilator weaning. Data were recorded for sequential 5 min period
Strong correlations were observed between the RSSs on PND 14, 21, and 28 and death or subsequent severe BPD. The RSS could provide a simple estimate of severe BPD or death., Further research with a larger study population is necessary to validate the usefulness of the RSS for predicting severe BPD or death.
The data in the present showed promising implications for using NIV-NAVA over NCPAP to facilitate extubation.
BACKGROUND: Neonatal sepsis is associated with most cases of mortalities and morbidities in the neonatal intensive care unit (NICU). Many studies have developed prediction models for the early diagnosis of bloodstream infections in newborns, but there are limitations to data collection and management because these models are based on high-resolution waveform data. OBJECTIVE: The aim of this study was to examine the feasibility of a prediction model by using noninvasive vital sign data and machin
<b><i>Background:</i></b> White matter injury (WMI) is the most common form of brain injury in preterm infants. It could be induced by a systemic inflammatory response in preterm infants. <b><i>Objectives:</i></b> We hypothesized that surgical necrotizing enterocolitis (surgNEC) results in more severe WMI than spontaneous intestinal perforation (SIP) on brain magnetic resonance imaging (MRI) at term-equivalent age (TEA). <b><i>Methods:&
BACKGROUND: Nutritional support is critical for preterm infants in the neonatal intensive care unit (NICU). A multidisciplinary nutritional support team (NST) that focuses on providing optimal and individualized nutrition care could be helpful. We conducted a thorough evaluation of clinical and nutritional outcomes in a tertiary NICU following the implementation of an NST. METHODS: This study used a retrospective approach with historical comparisons. Preterm neonates < 30 weeks gestational age o
The presence of an atrial left-to-right shunt was associated with PH in preterm infants with moderate or severe BPD. Close follow up is needed for infants with interatrial shunts, and a more tailored prognostic evaluation and treatment are recommended.
BACKGROUND: Several studies have suggested that adverse neurodevelopment could be induced by systemic inflammation in preterm infants. We aimed to investigate whether preterm infants with systemic inflammation would have impaired neurodevelopment and which biomarkers and neurophysiologic studies during inflammation are associated with poor neurodevelopment. METHODS: This prospective cohort study enrolled infants born before 30 weeks of gestation or with birth weight < 1250 g. Infants were groupe
Noninvasive Hb measurements with Pulse CO-Oximetry provide clinically acceptable accuracy, and they were significantly correlated with laboratory Hb measurement in neonates. In terms of the clinical applicability, noninvasive Hb monitoring with a pulse CO-oximeter could be useful in the early detection of Hb changes in neonates.
BACKGROUND: Thyroid hormones are critical for growth and brain development during the newborn period and infancy. Because of delayed maturation of the hypothalamic-pituitary-thyroid axis in preterm infants, thyroid dysfunction is common, and thyroid stimulating hormone (TSH) elevation is often delayed in preterm infants. The objective of this study was to determine the incidence of thyroid dysfunction requiring levothyroxine treatment and to identify its risk factors in preterm infants. METHODS:
The BK virus (BKV) can be reactivated with immunosuppressive treatment in renal allograft recipients, which can result in interstitial nephritis (BKV-associated nephropathy, BKVAN) and lead to renal allograft failure. Recently, leflunomide has been reported in some case series of BKVAN with favorable results. Most studies have included only adult patients, we herein report a pediatric case and include a literature review. The patient was a nine-yr-old female with end-stage renal disease due to h
Abstract The immature preterm kidney is likely to be vulnerable to acute kidney injury (AKI). However, the biomarkers currently used for AKI are not sensitive or specific and are also inadequate for the timely detection of AKI in preterm infants. The objectives of this study were to identify novel urinary biomarkers of AKI using proteomic techniques, and to verify and validate that the candidates can serve as early predictive biomarkers for AKI. In total, 1,810 proteins were identified in the di
BACKGROUND: Severe bronchopulmonary dysplasia often leads to prolonged mechanical ventilation lasting several months. Cyanotic episodes frequently occur in these patients, necessitating long-term sedation and/or intermittent muscle paralysis. Neurally adjusted ventilatory assist (NAVA) might provide precisely the amount of support that these patients need without sedation. METHODS: We reviewed the medical records of preterm infants who underwent tracheostomy and required mechanical ventilation f
OBJECTIVES: The aim of the present study was to report possible improvements in ventilator variables associated with a transition from synchronized intermittent mandatory ventilation to neurally adjusted ventilatory assist in preterm infants with bronchopulmonary dysplasia who required a high level of mechanical ventilatory support in a single center. DESIGN: Retrospective study. SETTING: Neonatal ICU. PATIENTS: Twenty-nine preterm infants with a median gestational age of 25.4 weeks (range, 23.4
