Evaluation of the clinical effect of a nationwide implementation of targeted routine antenatal anti-D prophylaxis in Denmark.

Background: In 2010, Denmark was the first country to implement a targeted routine antenatal anti-D prophylaxis (tRAADP) program, offering fetal RHD genotyping to all nonimmunized D negative pregnant women. The program represented a shift from only postnatal prophylaxis to a combined antenatal and postnatal prophylaxis. This study aimed to evaluate the clinical effect of tRAADP in Denmark.

Adverse Obstetric Outcomes in Pregnancies With Major Fetal Congenital Heart Defects.

Importance: Understanding the risk profile of obstetric complications in pregnancies with fetal major congenital heart defects (MCHDs) is crucial for obstetric counseling and care.

Objective: To investigate the risk of placenta-related adverse obstetric outcomes in pregnancies complicated by fetal MCHDs.

Design, Setting, And Participants: This cohort study retrieved data from June 1, 2008, to June 1, 2018, from the Danish Fetal Medicine Database, which includes comprehensive data on more than 95% of all pregnancies in Denmark since the database was instituted in 2008.

The Prevalence and Spontaneous Closure of Ventricular Septal Defects the First Year of Life.

Introduction: Ventricular septal defect (VSD) is one of the most common congenital heart defects. We aimed to determine the prevalence of VSD in a population-based cohort of newborns and assess the rate of spontaneous closure during the first 12 months of life.

Methods: The Copenhagen Baby Heart Study (CBHS) is a population-based cohort study, including more than 25,000 newborns born in the greater Copenhagen area.

Clinical implementation of first trimester screening for congenital heart defects.

Objective: To examine the feasibility and performance of implementing a standardized fetal cardiac scan at the time of a routine first-trimester ultrasound scan.

Method: A retrospective, single-center study in an unselected population between March 2021 and July 2022. A standardized cardiac scan protocol consisting of a four-chamber and 3-vessel trachea view with color Doppler was implemented as part of the routine first-trimester scan.

The use of paracetamol during pregnancy: A qualitative study and possible strategies for a clinical trial.

Paracetamol (N-acetyl-p-aminophenol (APAP), also known as acetaminophen) is used to relieve mild to moderate pain and reduce fever. APAP is widely used during pregnancy as it is considered safe when used as directed by regulatory authorities. However, a significant amount of epidemiological and experimental research suggests that prenatal exposure potentially alters fetal development.

Second-trimester cardiovascular biometry in growth-restricted fetuses; a multicenter cohort study.

Background: Intrauterine growth restriction is associated with an increased risk of cardiovascular changes neonatally. However, the underlying pathways are poorly understood, and it is not clear whether the dysfunction is already present in the fetus.

Objective: This study aimed to investigate fetal cardiac dimensions assessed from images at the second trimester anatomy scan from fetuses classified postnatally as small for gestational age and intrauterine growth restricted and compare them with appropriate for gestational age fetuses.

Prevalence of Bicuspid Aortic Valve and Associated Aortopathy in Newborns in Copenhagen, Denmark.

Importance: The prevalence and characteristics of bicuspid aortic valve (BAV) are mainly reported from selected cohorts. BAV is associated with aortopathy, but it is unclear if it represents a fetal developmental defect or is secondary to abnormal valve dynamics.

Objective: To determine the prevalence of BAV and BAV subtypes and to describe the associated aortopathy in a large, population-based cohort of newborns.

Prenatally detected isolated ventricular septum defects and the association with chromosomal aberrations-A nationwide register-based study from Denmark.

Objective: To evaluate the association between prenatally detected isolated ventricular septum defects (VSDs) and chromosomal aberrations in a nationwide study in Denmark.

Method: Nationwide, register-based study with prospectively collected data including all singleton pregnancies from 2014-2018. From the Danish Fetal Medicine Database, we retrieved data on maternal characteristics, first-trimester biomarkers, pre- and postnatal diagnoses, genetic test results, and pregnancy outcomes.

Refractory Fetal Supraventricular Tachycardia with Hydrops Successfully Converted by Intraperitoneal Flecainide in the Fetus: A Case Report.

Introduction: Supraventricular tachycardia is the most common fetal tachyarrhythmia and if persistent often associated with fetal hydrops which can cause intrauterine and neonatal death.

Case Presentation: We present a case of early second trimester supraventricular tachycardia in a hydropic fetus, initially refractory to transplacental treatment.

Conclusion: The supraventricular tachycardia was successfully treated when supplemented with intraperitoneal flecainide in the fetus.

Neonatal complications and neurophysiological development in twins - a long-term follow-up study.

Objectives: To investigate the association between neonatal complications and neurophysiological development in twins at 18 and 48-60 months of age.

Methods: This was a secondary analysis of 841 Danish mono- and dichorionic diamniotic twins from a randomized controlled trial (PREDICT study), which included an assessment of the twin's neurophysiological development using the Ages and Stages Questionnaire (ASQ) that had been filled out by the parents at 18 and 48 or 60 months. The correlation within twin pairs was accounted for by the method of generalized estimating equation.

Copenhagen Baby Heart Study: a population study of newborns with prenatal inclusion.

Congenital heart diseases (CHDs) are reported in 0.8% of newborns. Numerous factors influence cardiovascular development and CHD prevalence, and possibly also development of cardiovascular disease later in life.

Short- and long-term perinatal outcome in twin pregnancies affected by weight discordance.

Introduction: The objective was to investigate the association between chorionicity-specific intertwin birthweight discordance and adverse outcomes including long-term follow up at 6, 18, and 48-60 months after term via Ages and Stages Questionnaire.

Material And Methods: In this secondary analysis of a cohort study (Oldenburg et al., n = 1688) and a randomized controlled trial (PREDICT study, n = 1045) twin pairs were divided into three groups according to chorionicity-specific birthweight discordance: <75th percentile, 75th-90th percentile and >90th percentile.

Medical students as facilitators for laparoscopic simulator training.

Background: Teaching basic clinical skills to student peers and residents by medical students has previously been shown effective. This study examines if medical students can facilitate laparoscopic procedural tasks to residents using a virtual reality simulator.

Methods: This was a retrospective study comparing 2 groups of gynecology residents.
