Bronchopulmonary dysplasia (BPD) is characterized by arrest of vascular and alveolar development in premature infants. Recent advances in neonatology have increased the survival of immature babies. Consequently, the prevalence of BPD is increasing. Animal studies and autopsy findings of BPD have demonstrated interruption in vascular development and reversal of lung injury through promotion of vasculogenesis. Normal lung development is driven by temporal and spatial specific growth factors and cell- to- cell signaling in vascular development. Lung injury through various pathways causes disruption in this complex interactive process and results in aberrant vascular development and subsequent BPD. By understanding the regulation of vascular growth of the lung, it would be possible to find new targets in the treatment and prevention of BPD in premature infants.

Early nutritional support for preterm infants is critical because such support influences long-term outcome. Minimal enteral feeding should be initiated as soon as possible if an infant is stable and if feeding advancement is recommended as relevant to the clinical course. Maternal milk is the gold standard for enteral feeding, but fortification may be needed to achieve optimal growth in a rapidly growing premature infant. Erythromycin may aid in promoting gastrointestinal motility in cases that exhibit feeding intolerance. Selected preterm infants need vitamins, mineral supplements, and calorie enhancers to meet their nutritional needs. Despite all that is known about this topic, additional research is needed to guide postdischarge nutrition of preterm infants in order to maintain optimal growth and neurodevelopment.

Debriefing is a conversational session that revolves around the sharing and examining of information after a specific event has taken place. Debriefing may follow a simulated or actual experience and provides a forum for the learners to reflect on the experience and learn from their mistakes. Originating from the military and aviation industry, it is used on a daily basis to reflect and improve the performance in other high-risk industries. Expert debriefers may facilitate the reflection by asking open-ended questions to probe into the framework of the learners and apply lessons learned to future situations. Debriefing has been proven to improve clinical outcomes such as the return of spontaneous circulation after cardiac arrest and the teaching of teamwork and communication in pediatrics. Incorporating debriefing into clinical practice would facilitate the cultural change necessary to talk more openly about team performance and learn from near misses, errors, and successes that will improve not only clinical outcome but also patient safety.

Clinical trials in neonates of different gestational age, birth weight, postnatal age and general health status are needed to assure safe and optimal evidence-based-therapy to this special population. Pharmacodynamic maturation must be considered in grouping the neonates for clinical trials. Informed consent from the parents, protection of the neonates participating in the clinical trials, adherence to good clinical practice guidelines, and designation of short term and long term outcomes must be taken into consideration from the beginning of the trials. Collaboration between centers will be helpful in overcoming the problem with small patient size. Many of these challenges are surmountable and an well-designed clinical trial will improve the mortality and morbidity in these very small children.

Breast milk is the gold standard for full term babies as well as premature babies. Breast milk provides nutritional, gastroenterological, immunological, neurodevelopmental and psychological benefits to the premature baby. These benefits decrease acute morbidities and provide long term benefits. Despite the knowledge that breast milk is best, many obstacles must be overcome for a premature infant to receive optimal nutrition from breast milk. Insufficient amount and difficulty in pumping are some issues that are easily solved with education and support. Inadequacy of minerals and electrolytes in breast milk after one month may be overcome with the use of commercial fortifiers for the optimal growth of the growing premature baby. The use of donor breast milk is increasing. It is the responsibility of the medical personnel to promote breast milk in premature babies by being concerned about the obstacles and preventing problems from arising beforehand.

PURPOSE: There have been limited studies investigating the relationship between high-sensitivity C-reactive protein (hsCRP), metabolic diseases, and dietary factors in Korean adults. Here, we examined the association between nutrient intake and serum hsCRP among Korean adults. METHODS: Using data on 2,624 healthy Korean adults (1,537 women and 1,087 men) from the 2015 Korea National Health and Nutrition Examination Survey, demographic, anthropometric, biochemical, and dietary factors were analyzed once the subjects were grouped into either sex, age, or BMI. Nutrient intake was evaluated using the dietary data obtained by one-day 24-hour recall. Based on the guidelines of the US Centers for Disease Control and Prevention and the American Heart Association, hsCRP level was classified as HCRPG (High CRP Group, hsCRP > 1 mg/L) and LCRPG (Low CRP Group, hsCRP ≤ 1 mg/L). Proc surveyreg procedure was performed to examine the associations between nutrient intake and hsCRP after adjustment for potential confounding variables. RESULTS: The average hsCRP level of healthy Korean adults was 0.95 ±0.03 mg/L (0.97 ±0.04 mg/L in men, 0.92 ±0.05 mg/L in women). Obese subjects had significantly higher hsCRP than non-obese subjects in both sexes. The hsCRP level was positively associated with current smoking, physical inactivity, BMI, waist circumference, fasting blood glucose, triglycerides, total cholesterol, LDL-cholesterol, and blood pressure and inversely associated with HDL-cholesterol. LCRPG had significantly higher intake of dietary fiber compared to HCRPG in women. High hsCRP level was associated with more dietary cholesterol intake but less omega-3 fatty acid intake among subjects aged ≥ 50y. HCRPG of obese subjects had higher intakes of fat and saturated fatty acid than LCRPG. CONCLUSION: The hsCRP level is closely associated with several lifestyle variables and nutrient intake in healthy Korean adults. Individuals with high hsCRP level show low intakes of dietary fiber and omega-3 fatty acids but high intakes of dietary fat and cholesterol. Our findings suggest that a potential anti-inflammatory role for nutrients and lifestyle in the Korean adult population.

PURPOSE: An increase in the breastfeeding rate has been followed by an increase in the number of mothers seeking help in relactation. We investigated the factors related to successful relactation by assessing the impact of medications, supplementer, consultations, and family support. METHODS: A retrospective review of the medical records and telephone survey of mothers who had visited the relactation clinic were conducted from January 2004 to April 2007. RESULTS: Data from 84 mothers were analyzed to identify the factors associated with success in relactation. Seventy-five percent of the mothers succeeded in obtaining exclusive breastfeeding. Success in relactation was associated with informed referral from medical personnel, the use of galactogogues, and family support. CONCLUSION: This study provides new and noteworthy insights concerning relactation. This highlights the need to inform the mothers about the data of relactation, to use galactogogues, and to have their families involved for psychological support and endurance during visits to the relactation clinic.

Group B Streptococcus (GBS) commonly causes neonatal meningitis and sepsis. In infants with late-onset meningitis, fever, irritability or lethargy or both, poor feeding, and tachypnea are common initial signs. Major neurologic sequelae are observed in 29% of children, the most serious including global or profound mental retardation, spastic quadriplegia, cortical blindness, deafness, uncontrolled seizures, hydrocephalus, and hypothalamic dysfunction. We report a 14-day-old full-term female infant who presented with grunting and irritability to the emergency room and was diagnosed with GBS meningitis subsequently complicated with central diabetes insipidus and secondary hypopituitarism. Central diabetes insipidus should be ruled out in infants with complicated GBS meningitis.

PURPOSE: Nephrocalcinosis (NC) is frequently observed in premature infants. Small-scale studies have suggested that NC adversely affects renal function; however, the etiologic factors are still unclear. This prospective observational study aimed to identify the factors that influence the development of NC, through urine analysis. METHODS: In total, 99 preterm infants (gestational age <34 weeks) diagnosed with NC in the neonatal intensive care unit (NICU) from October 2010 to March 2014 were evaluated. Data regarding perinatal characteristics, respiratory support, total parenteral nutrition (TPN), and use of nephrotoxic drugs were analyzed. After an ultrasonographic diagnosis of NC, the infants were subjected to biweekly urine tests along with ultrasonographic follow-ups until the resolution of NC, in the outpatient department. RESULTS: NC was diagnosed in 23% (99/432) of the preterm infants admitted to the NICU. Their median gestational age and birth weight were 28?³ (range:23??-35?²) weeks and 1,120 (range: 560-1,950) g, respectively. NC was diagnosed an average of 26.4±2.8 (range: 2-82) days after birth, and the corrected gestational age at that time was 32.4±2.0 weeks. Preterm infants with NC had hyperoxaluria (oxalate/Cr=4.1 [oxalate/Cr<0.3]), and low urinary citrate levels (citrate/Cr=0.03 [citrate/Cr>0.51]). The follow-up rate was 52% (27/52) and symptoms in none of the infants had progressed to nephrolithiasis. In the infants that were followed up, NC was resolved at a mean age of 7.7 (range: 2-32) months. CONCLUSION: Our results suggest that hyperoxaluria is a significant risk factor for the development of NC.
