In Korea, the birth rate is declining at an alarming pace. This study aimed to investigate changes and trends in population count, number of births, past future.Data regarding total crude rate, fertility were collected from "Statistics Korea Census" national statistical portal, census report, Statistics Korea's "2020 Population Trend Survey for 1981-2020, provisional results death statistics." We used Organisation Economic Co-operation Development 2019 Family Database TFR. To develop a...

The purpose of this study was to evaluate the importance collateral vessels in CT diagnosis superior vena cava syndrome. Forty-seven patients with evidence obstruction or compression its major tributaries were included study. Contrast-enhanced scans had been obtained a combined bolus and drip-infusion technique. We evaluated scans, particular attention presence (and if present, their location), without knowing patients' clinical histories. On reviewing charts, we found 23 signs symptoms then...

Background: As the aging society progresses, average age of mothers is also increasing.Advanced maternal has been known to be associated with perinatal outcomes, as well birth weight (BW).In this study, we aimed investigate factors low infants (LBWIs) using statistics Korean population.Methods: Birth between 1993 and 2016 from Statistical Information Service were reviewed.We investigated 12,856,614 data points, which included number births, BWs, percentage preterm births LBWIs, multiple...

Human milk banks are a solution for mothers who cannot supply their own breast to sick or hospitalized infants; premature infants, in particular, unable receive full volume of numerous reasons. As December 2015, there was only one bank university hospital Korea. We reviewed the basic characteristics donors and recipients, amounts contamination donated at Milk Bank Kyung Hee University Hospital Gangdong Korea from 2008 2015. The donor pool consisted 463 first-time 452 repeat made 1,724...

The Pediatric Growth Chart (2007) is used as a standard reference to evaluate weight and height percentiles of Korean children adolescents. Although several previous studies provided useful range newborn birth (BW) by gestational age (GA), the BW analyzed sex plurality not currently available. Therefore, we aimed establish national neonatal considering GA, sex, newborns in Korea. raw data all (470,171 2010, 471,265 2011, 484,550 2012) were analyzed. Using Statistical Information Service...

Pulmonary surfactants, a complex assembly of phospholipids and surfactant proteins such as SP-B SP-C, are critical for maintaining respiratory system functionality by lowering surface tension (ST) preventing alveolar collapse. Our study introduced five synthetic peptides one SP-C peptide, leading to the synthesis CHAsurf candidates (CHAsurf-1 CHAsurf-5) evaluation. We utilized modified Wilhelmy balance test assess properties measuring spreading rate, adsorption, ST-area diagrams...

The risks and benefits of feeding preterm formula (PF) versus donor human milk (DHM) in infants are uncertain, studies evaluating the efficacy DHM to morbidities growth neonatal intensive care unit confused by need for fortification. We aimed determine compare outcome short-term between premature fed exclusively only until a volume 130 mL/kg/d enteral was achieved with PF mix after birth. data 132 low birth weight <1500 g gestational age less than 32 weeks were considered. Ninety analyzed,...

Neonatal mortality rate (NMR) or infant (IMR) are the of deaths per 1,000 live births at which babies either less than four weeks one year age die, respectively. The NMR and IMR commonly accepted as a measure general health wellbeing population. Korea's fell significantly between 1993 2009 from 6.6 9.9 to 1.7 3.2, Common causes infantile death in 2008 had decreased compared with those 1996 such other disorders originating perinatal period, congenital malformation heart, bacterial sepsis...

Risk Factors for Cause-specific Mortality of Very-Low-Birth-Weight Infants in the Korean Neonatal NetworkThis study attempted to assess risk factors mortality very-low-birth-weight (VLBW) infants neonatal intensive care unit (NICU, n = 2,386).Using data from Network, we investigated with birth weights < 1,500 g and gestational ages (GAs) 22-31 weeks born between January 2013 June 2014.Cases were defined as death at NICU discharge.Controls randomly selected live VLBW frequency matched case...

Hypernatremic dehydration is an important cause of intracranial hemorrhage. A possible association intraventricular hemorrhage (IVH) with hypernatremia and/or high sodium intake has been suggested in preterm infants. To investigate the associations early fluid and or serum concentrations severe extremely low birth weight (ELBW) infants, we reviewed medical records 169 inborn ELBW Daily intake, urine output, loss concentration during first 4 days life were obtained. Patients divided into IVH...

Respiratory distress syndrome (RDS) is a disease that commonly affects premature infants whose lungs are not fully developed. RDS results from lack of surfactant in the lungs. The more infant is, greater likelihood having RDS. However, even though all have RDS, preemptive treatment with artificial pulmonary administered most cases.We aimed to develop an intelligence model predict avoid unnecessary treatment.In this study, 13,087 very low birth weight who were newborns weighing less than 1500...

Rationale: Persistent pulmonary hypertension of the newborn (PPHN) is a syndrome failed circulatory adaptation at birth with persisting increased vascular resistance that associated high mortality rates especially in preterm infants. Patient concerns: We reported 2 cases PPHN infants respiratory distress and early onset sepsis refractory to therapy vasopressors, inotropes, inhaled nitric oxide (iNO), whom treatment treprostinil was successful. Diagnoses: Infants showed difference more than...

Air pollution has become a global concern due to its association with numerous health effects. We aimed assess associations between birth outcomes in Korea, such as preterm births and weight term infants, particulate matter &lt; 10 µm (PM10). Records from 1,742,183 single 2010–2013 were evaluated. Mean PM10 concentrations during pregnancy calculated matched data by registered regions. analyzed the frequency of groups using WHO criteria for effect sizes estimated multivariate logistic...

&lt;b&gt;&lt;i&gt;Background:&lt;/i&gt;&lt;/b&gt; Management of newborn infants with congenital anomalies is challenging and requires a multidisciplinary approach. The prevalence in very-low-birth-weight (VLBWIs; birth weight &amp;#x3c;1,500 g) has been rarely reported. &lt;b&gt;&lt;i&gt;Objectives:&lt;/i&gt;&lt;/b&gt; aim this study was to investigate the epidemiology VLBWIs association early mortality major morbidities. &lt;b&gt;&lt;i&gt;Study Design:&lt;/i&gt;&lt;/b&gt; A prospective...
