OBJECTIVE: To evaluate the trends in survival for infants with critical congenital heart defects (CCHDs) and to examine the potential impact of timing of diagnosis and other prognostic factors on survival. METHODS: We performed a retrospective population-based cohort study in infants born with structural congenital heart defects (CHDs) between 1979 and 2005 and ascertained by the Metropolitan Atlanta Congenital Defects Program. We estimated Kaplan-Meier survival probabilities for 12 CCHD phenoty

We suggest that Bayesian filtering (PopBayes) is a customizable and useful tool in establishing a model for the prediction of preterm birth.

본 연구는 여성주의 평등 정치학에서 생물학적 결정론을 극복하기 위해 모성을 거부하는 전략을 취하는데 대한 문제의식에서 출발한다. 연구자는 남성적 ‘개인주의’가 여성에게 씌운 ‘본질적 모성’이라는 함정을 피하기 위해, 모성에 대한 문화적 공명을 만들어 내는 일까지 포기하는 것은 오류라고 본다. ‘모성을 생각할 수 있는 능력’은 남성적 상징 질서를 근본적으로 넘어서려 할 때 꼭 필요한 능력이기 때문이다. 따라서 본 논문은 여성주의 내부의 본질주의 모성론을 비판해내고 모성에 대한 다른 문화적 이미지를 구축하는 것을 목적으로 한다. 그러기 위해 다음과 같은 이론적 작업을 수행하고자 한다. 첫째, 여성주의 평등 정치학의 모성에 대한 거부를 ‘가부장적 자연화’라는 맥락에서 설명하고 그 논리적 오류를 짚는다. 둘째, 모성을 여성이 갖는 하나의 생물학적 차이로서 어떻게 본질주의적이지 않은 방식으로 옹호할 수 있는지를 논한다. 셋째, 개인주의 정치학 안에 내재되어 있는 존재론을 모성과 관련하여 비판

We suggest that urinary nephrin can be used as an early marker in pregnancies at risk for developing PE and SGA infants.

Throughout the COVID-19 pandemic, pregnant women have been classified as a vulnerable population. However, the evidence on the effect of infection during pregnancy on maternal and neonatal outcomes is still uncertain, and related research comprising a large population of pregnant women in Asian countries is limited. We constructed a national cohort including mothers and children (369,887 pairs) registered in the Prevention Agency-COVID-19-National Health Insurance Service (COV-N), from January 1

BACKGROUND: Despite increasing evidence that human parturition is associated with alteration in gene expression in the uteroplacental unit, the precise mechanisms that elicit spontaneous term labor in humans remain unknown. Our goal in this study was to compare the mRNA expression pattern of the trophoblast layer of normal term placenta between women who had given natural birth (labor group) and those who had undergone an elective cesarean section without labor (non-labor group). METHODS: We col

Background: Obstructed hemivagina and ipsilateral renal agenesis (OHVIRA) syndrome, also known as Herlyn-Werner-Wunderlich syndrome, is a rare syndrome characterized by the triad of uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis. Most cases of OHVIRA have been reported in adolescents or adults. Gartner duct cysts, including those manifesting as vaginal wall cysts, are also rare. Fetal OHVIRA syndrome and Gartner duct cysts are difficult to diagnose. Case Presentation: He

2000년대 이후 우리나라는 저개발국가들의 빈곤 퇴치와 경제 성장에 기여하기 위한 방안으로 공적개발원조의 규모를 증가시키고 있다. 본 연구의 목적은 국가간 원조가 수혜국의 경제 성장에 미치는 효과를 실증적으로 분석하는 것이다. 특히 본 연구는 원조 수혜국들을 수출 비중에 따라 두 집단으로 분류하여 원조 유입에 따른 Dutch Disease 현상이 두 집단 간에 어떻게 다르게 나타나는지를 분석한다. 본 연구의 분석 결과에 의하면 첫째, 전반적으로 볼 때 원조는 수혜국의 경제 성장에 긍정적인 효과를 가져 오며, 원조 유입으로 인한 Dutch Disease 현상은 뚜렷하게 관찰되지 않는다. 둘째, 그러나 수출 비중이 높은 수혜국의 경우에는 원조 유입이 실질 환율의 절상을 통하여 수출과 GDP 성장을 저해하는 부정적인 효과도 존재하는 것으로 나타난다. 다만 이 경우에도 원조의 부정적인 효과가 긍정적인 효과를 압도하지는 않는 것으로 보인다.

OBJECTIVES: Although previous epidemiological studies have reported the effects of fetal exposure to phthalates and phenols on birth outcomes, evidence is still limited. The objective of this study was to investigate whether prenatal exposure to endocrine-disrupting chemicals [EDCs; phthalates and bisphenol A (BPA)] is associated with birth outcomes and whether there are sex-specific effects. METHODS: We used data from the Korean CHildren's ENvironmental health Study (Ko-CHENS) cohort. Exposure

Objective: The study aimed to investigate the clinical outcomes of fetuses diagnosed with isolated mega cisterna magna in utero. Methods: A multicenter retrospective cohort study was conducted across 18 university hospitals from 2010 to 2019. Cases diagnosed with isolated mega cisterna magna, defined as a cisterna magna >10 mm with a normal cerebellar vermis and no cystic dilation of the fourth ventricle, were included. Cases with other central nervous system (CNS) anomalies, extra–central ne

Background and Objectives: Preterm birth (PTB), defined as delivery before 37 weeks of gestation, remains a significant public health concern due to its association with neonatal morbidity and mortality. Although studies have suggested that microbial factors in vaginal microbiota (VMB) influence PTB, longitudinal research on Korean women is limited. This study aimed to analyze VMB differences between term and preterm pregnancies in Korean women and their correlation with the cervical length (CL)

Fetal growth restriction (FGR) is one of the leading causes of perinatal morbidity and mortality. Many studies have reported an association between FGR and fetal Doppler indices focusing on umbilical artery (UA), middle cerebral artery (MCA), and ductus venosus (DV). The uteroplacental-fetal circulation which affects the fetal growth consists of not only UA, MCA, and DV, but also umbilical vein (UV), placenta and uterus itself. Nevertheless, there is a paucity of large-scale cohort studies that
