Atrial fibrillation (AF) is a really uncommon arrhythmia in newborns. Here, we report the case of a 1-day-old infant who was recovered in Neonatal Intensive Care Unit for a twin-to-twin transfusion. The appearance of an unexpected AF was registered at his continuous electrocardiographic monitoring. Both chest X-ray and echocardiographic examination revealed the anomalous insertion of the tip of a central venous catheter (CVC) into the heart ('umbilical artery → inferior vena cava → right atrium → patent foramen ovale → left atrium')...

BACKGROUND: Twin-Twin Transfusion Syndrome (TTTS) is associated with an increased risk of perinatal mortality and morbidity. Several treatment interventions have been described for TTTS, including fetoscopic laser surgery, amnioreduction, septostomy, expectant management, and pregnancy termination. Over the last decade, fetoscopic laser surgery has become the primary treatment. The literature to date reports on many different outcomes, making it difficult to compare results or combine data from individual studies, limiting the value of research to guide clinical practice...

BACKGROUND: Aggregation of end-stage renal disease (ESRD) has been observed in families of European origin, as well as those of African origin. However, it is not well documented if this disease aggregates in Asian families. Furthermore, the contribution of genetic factors and shared environmental factors to family aggregation remains unclear. STUDY DESIGN: Population-based cross-sectional cohort study. SETTING & PARTICIPANTS: All 23,422,955 individuals registered in the Taiwan National Health Insurance Research Database in 2013...

BACKGROUND: Ecstasy is a widely used psychoactive drug that users often take because they experience positive effects such as increased euphoria, sociability, elevated mood, and heightened sensations. Ecstasy use is not harmless and several immediate and long term side effects have been identified. Lifetime ecstasy use is likely to be partly influenced by genetic factors, but no twin study has determined the heritability. Here, we apply a classical twin design to a large sample of twins and siblings to estimate the heritability of lifetime ecstasy use...

PURPOSE: Work-home interference has been proposed as an important explanation for sickness absence (SA). Previous studies show mixed results, have not accounted for familial factors (genetics and shared everyday environment), or investigated diagnosis specific SA. The aim was to study whether work-home interference and perceived total workload predict SA due to stress-related mental diagnoses, or SA due to other mental diagnoses, among women and men, when adjusting for various confounders and familial factors...

BACKGROUND: There is limited information regarding the association between youth mental health problems and work incapacity in adulthood. We investigated whether internalizing (depressive, anxious, somatic complaints) and externalizing (aggressive, rule-breaking) behavior problems in childhood and adolescence were associated with sickness absence (SA) and disability pension (DP) in young adulthood. METHODS: Data were used from the population-based and prospective Twin Study of Child and Adolescent Development (TCHAD) which includes all Swedish twins born in 1985-1986 (N = 2570)...

Conduct problems in children and adolescents can predict antisocial personality disorder and related problems, such as crime and conviction. We sought an explanation for such predictions by performing a genetic longitudinal analysis. We estimated the effects of genetic, shared environmental, and unique environmental factors on variation in conduct problems measured at childhood and adolescence and antisocial personality problems measured at adulthood and on the covariation across ages. We also tested whether these estimates differed by sex...

OBJECTIVE: Resting heart rate (RHR) possibly has a hereditary component and is associated with longevity. We used the classical biometric twin study design to investigate the heritability of RHR in a population of middle-aged and elderly twins and, furthermore, studied the association between RHR and mortality. METHODS: In total, 4282 twins without cardiovascular disease were included from the Danish Twin Registry, hereof 1233 twin pairs and 1816 'single twins' (twins with a non-participating co-twin); mean age 61...

Yaniv Zipori, Jigal Haas, Howard Berger, Eran Barzilay
The current systematic review and meta-analysis evaluate the perinatal outcomes in twin pregnancies following multifetal pregnancy reduction (MPR) compared with non-reduced triplet pregnancies. All studies comparing perinatal outcome of twin pregnancies following MPR to non-reduced triplet pregnancies were considered. MEDLINE, non-indexed MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and Web of Science were searched for relevant published articles up to August 2016. The search yielded 653 publications of which 92 were assessed for eligibility...

Obese individuals are characterized by altered brain reward responses to food. Despite the latest discovery of obesity-associated genes, the contribution of environmental and genetic factors to brain reward responsiveness to food remains largely unclear. Sixteen female monozygotic twin pairs with a mean BMI discordance of 3.96 ± 2.1 kg/m(2) were selected from the Netherlands Twin Register to undergo functional MRI scanning while watching high- and low-calorie food and non-food pictures and during the anticipation and receipt of chocolate milk...

Introduction: Classical twin studies show that smoking is heritable. To determine if shared family environment plays a role in addition to genetic factors, and if they interact (GxE), we use a children-of-twins design. In a second sample, we measure genetic influence with polygenic risk scores (PRS) and environmental influence with a question on exposure to smoking during childhood. Methods: Data on smoking initiation were available for 723 children of 712 twins from the Netherlands Twin Register (NTR;64...

BACKGROUND: Severe preeclampsia is a disorder of pregnancy characterized by high blood pressure and significant proteinuria after 20 weeks gestation. Severe preeclampsia and eclampsia have considerable adverse impacts on maternal, fetal, and neonatal health especially in low-resource countries. Hypertensive disorders of pregnancy are the third leading cause of maternal deaths in Sub-Saharan Africa. Significant avoidable maternal and neonatal morbidity and mortality may result. OBJECTIVES: This study aimed 1) to determine the incidence of severe preeclampsia/eclampsia in a low-resource setting; 2) to determine the maternal complications of severe preeclampsia/eclampsia in a low-resource setting; 3) to determine the perinatal outcomes of severe preeclampsia/eclampsia in a low-resource setting...

PURPOSE: Nationwide data have been lacking on drug abuse (DA)-associated mortality. We do not know the degree to which this excess mortality results from the characteristics of drug-abusing individuals or from the effects of DA itself. METHOD: DA was assessed from medical, criminal, and prescribed drug registries. Relative pairs discordant for DA were obtained from the Multi-Generation and Twin Registers. Mortality was obtained from the Swedish Mortality registry...

BACKGROUND: Monochorionic twin pregnancies are at increased risk of complications due to sharing a single placenta and potentially developing unbalanced vascular anastomoses. Complications include twin-twin transfusion syndrome (TTTS) which affects 10-15% monochorionic twins, and if untreated has a 70-90% perinatal loss rate. We are currently unable to predict which twins will develop complications or to what severity. We have previously shown differences in angiogenic and placental growth factors in maternal blood in pregnancies complicated by TTTS compared to twin pregnancies not complicated by TTTS but matched for gestation...

BACKGROUND: Autism Spectrum Disorders (ASD) are highly heritable, but the exact etiological mechanisms underlying the condition are still unclear. METHODS: Using a multiple rater twin design in a large sample of general population preschool twins, this study aimed to (a) estimate the contribution of genetic and environmental factors to autistic traits, controlling for the possible effects of rater bias, (b) to explore possible sex differences in etiology and (c) to investigate the discordance in autistic traits in monozygotic and same-sex dizygotic twin pairs...

BACKGROUND: Hall (Embryologic development and monozygotic twinning. Acta Geneticae Medicae et Gemellologiae, Vol. 45, 1996, pp. 53-57) hypothesized that chromosomal aberrations can lead to monozygotic (MZ) twinning. However, twinning and chromosomal aberrations increase prenatal mortality and could reduce the prevalence of chromosomal aberrations in live-born twins. We compared prevalence proportion ratios (PPR) of chromosomal aberrations and trisomy 21 (T21) in live-born twins versus singletons born in Denmark during 1968-2009...

STUDY QUESTION: Is pregnancy outcome in triplet pregnancies improved with embryo reduction (ER) to twins compared to expectant management? SUMMARY ANSWER: In trichorionic triplet pregnancies, ER to twins reduces the risk of preterm birth (<34 weeks) without significantly increasing the risk of miscarriage (<24 weeks), whereas in dichorionic triplet pregnancies, the results are inconclusive. WHAT IS KNOWN ALREADY: Triplet pregnancies are associated with a high risk of miscarriage and preterm birth...

BACKGROUND: Early age at illness onset has been viewed as an important liability marker for schizophrenia, which may be associated with an increased genetic vulnerability. A twin approach can be valuable, because it allows for the investigation of specific illness markers in individuals with a shared genetic background. METHODS: We linked nationwide registers to identify a cohort of twin pairs born in Denmark from 1951 to 2000 (N=31,524 pairs), where one or both twins had a diagnosis in the schizophrenia spectrum...

Congenital heart defects (CHD) constitute the largest group of congenital malformations. In most families, only one person has CHD; however, the risk of CHD increases for children born into families already affected. In this study, all births from 1994 through 2009 were identified in the Medical Birth Registry of Norway, including supplemental information on CHD from clinical and administrative registers, as part of the CVDNOR project. By using the unique personal identification number of each parent we were able to link 16,078 pairs of twins, 445,584 pairs of full siblings, and 106,840 pairs of half-siblings...
