The Twin Interdisciplinary Neuroticism Study
Authors: Riese Harriëtte , Rijsdijk Frühling V. , Snieder Harold , Ormel Johan
Published: November 2012

The Twin Interdisciplinary Neuroticism Study (TWINS) is a three-wave study including >800 twin pairs from the northern part of the Netherlands. The aim of the study is to unravel why neuroticism reflects vulnerability to mental disorders. In this study, we focus on possible mechanisms underlying this vulnerability and their genetic and environmental origins. In total, 125 female twin pairs visited our psychophysiological laboratory. From these twin pairs DNA was isolated and both candidate gene and genome-wide genotyping were conducted. Future work includes studies of candidate genes. The study also participates in several meta-genome-wide association study (GWAS) consortia.

Published: November 2012

Twin studies of Africans have been scarce although Africans have shown the highest twin birth rate in the world. As a parallel study of the South Korean Twin Registry, the Nigerian Twin and Sibling Registry (NTSR) was developed to understand causal influences on the development of cognitive abilities, personality, and mental health among Nigerians. Currently, 1,134 twins and 404 full- and half-siblings have been registered with NTSR. This article describes research background, goals, major recruitment strategies, measures, and future directions of the NTSR.

We describe the importance of the Norwegian Twin Registry (NTR) for research in public health and provide examples from several programs of twin research at the Norwegian Institute of Public Health (NIPH), including the Nordic Twin Study of Cancer, our epigenetics platform, and our large program of research in mental health. The NTR has become an integral component of a national strategy for maximizing the research potential from Norwegian registries and biobank-based studies. The information provided herein builds upon and complements our recent report describing the establishment of the NTR and the cohorts comprising it. Although Norway has a long tradition in twin research, the centralization and administration of the twin data through a single register structure is fairly recent. The NTR was established in 2009 and currently includes 47,989 twins covering birth years 1895–1960 and 1967–1979; 31,440 of these twins have consented to participate in medical research (comprising 5,439 monozygotic pairs, 6,702 dizygotic same-sexed pairs, and 1,655 dizygotic opposite-sexed pairs). DNA from approximately 4,800 twins is banked at the NIPH biobank and new studies continuously add new data to the registry. The value of NTR data is greatly enhanced through record linkage possibilities offered by Norway's many nation-wide registries (medical, demographic, and socio-economic) and several studies are already taking advantage of these linkage opportunities for research.

The Netherlands Twin Register (NTR) began in 1987 with data collection in twins and their families, including families with newborn twins and triplets. Twenty-five years later, the NTR has collected at least one survey for 70,784 children, born after 1985. For the majority of twins, longitudinal data collection has been done by age-specific surveys. Shortly after giving birth, mothers receive a first survey with items on pregnancy and birth. At age 2, a survey on growth and achievement of milestones is sent. At ages 3, 7, 9/10, and 12 parents and teachers receive a series of surveys that are targeted at the development of emotional and behavior problems. From age 14 years onward, adolescent twins and their siblings report on their behavior problems, health, and lifestyle. When the twins are 18 years and older, parents are also invited to take part in survey studies. In sub-groups of different ages, in-depth phenotyping was done for IQ, electroencephalography , MRI, growth, hormones, neuropsychological assessments, and cardiovascular measures. DNA and biological samples have also been collected and large numbers of twin pairs and parents have been genotyped for zygosity by either micro-satellites or sets of short nucleotide polymorphisms and repeat polymorphisms in candidate genes. Subject recruitment and data collection is still ongoing and the longitudinal database is growing. Data collection by record linkage in the Netherlands is beginning and we expect these combined longitudinal data to provide increased insights into the genetic etiology of development of mental and physical health in children and adolescents.
Long-term Effects of a Multimodal Behavioural ADHD Training: a fMRI Study
Authors: Sotnikova Anna , Steinmann Elisabeth , Wendisch Vanessa , Müller Gabriele Gerber-von , Stephani Ulrich , Petermann Franz , Gerber Wolf-Dieter , Siniatchkin Michael
Published: November 2012

Several studies have demonstrated that behavioural therapy oriented interventions exert a positive influence on the clinical course of the attention-deficit hyperactivity disorder (ADHD). However, the long-term effects of the behavioral treatment in ADHD, especially those on neuronal mechanisms underlying this disorder, have been studied insufficiently. Functional MRI (Go-NoGo paradigm) was carried out in 9 children with ADHD before and 1.5 years after a response cost and token-based training. In the follow-up, patients were still characterized by a significant increase in activation in the anterior cingulate and in the precentral gyrus compared with recordings done before the training. It seems likely that the behavioural training elicits stable neuronal changes in children with ADHD which correspond with an improvement of neuropsychological functioning and clinical symptoms.

Bei der ADHS handelt es sich um eine psychische Krankheit, die sich über die Lebenspanne erstreckt und durch einen Symptomwandel im Zeitverlauf gekennzeichnet ist. Eine notwendige Differenzierung der Symptome und Erscheinungsformen wurde durch neuropsychologische und neurobiologische Methoden möglich. Idealerweise sollte eine neurowissenschaftlich orientierte Diagnostik multimodal ausgerichtet sein ( = neuropsychologische Testverfahren, Bildgebung).
Risiken in Familien

Published: November 2012

Risiken in der Familie werden unter dem Blickwinkel der elterlichen Erziehungskompetenz und Sensitivität für die Bedürfnisse von Kindern betrachtet. Als besondere Belastungen in der kindlichen Entwicklung sind Misshandlungen/Missbrauch durch die eigenen Eltern und psychische Krankheiten der Eltern anzuführen. Solche Extremsituationen für Kinder können durch neue familienorientierte Behandlungsansätze in ihren Auswirkungen begrenzt werden. Die Kenntnis von familiären Risikofaktoren ermöglicht auch den Einsatz von Präventionsmaßnahmen.

Published: November 2012

Die elterliche Sensitivität gegenüber Kleinkindern ist eine zentrale Erziehungsfertigkeit und trägt wesentlich zur gesunden Entwicklung des Kindes bei. In der bisherigen Forschung wurden einige Risiko- und Schutzfaktoren der elterlichen Sensitivität ermittelt. Ergänzend zu bestehenden Studien wurden die Determinanten der Sensitivität von jeweils 91 Müttern und Vätern derselben Familien im Quer- und Längsschnitt erforscht. Die Datenerhebung erfolgte im Alter des Kindes von fünf und 15 Monaten mittels Fragebogen. Die Ergebnisse der Querschnitterhebung replizierten mehrheitlich die Befunde der Literatur, jedoch nur für die Mütter und nicht für die Väter. Weitere Unterschiede fanden sich zwischen den Quer- und Längsschnittergebnissen. Die Befunde lassen auf grundlegende Unterschiede in den Determinanten der Sensitivität von Müttern und Vätern schliessen.
Wer wird Kinder- und Jugendlichenpsychotherapeut?
Authors: Jungbauer Johannes , Berg Mathias , Düvel Julia , Kahl Yvonne
Published: November 2012

In diesem Beitrag werden Ergebnisse einer Studie vorgestellt, bei der n=272 Kinder- und Jugendlichenpsychotherapeuten in Ausbildung befragt wurden. Zusätzlich wurden statistische Daten der kooperierenden Ausbildungsinstitute in die Auswertung einbezogen. Neben dem Anteil der unterschiedlichen Berufsgruppen unter den Ausbildungsteilnehmern sollten deren berufsbezogene Motive und Zielperspektiven untersucht werden, ferner ihre Bewertungen bezüglich der im Studium erworbenen berufsrelevanten Kompetenzen. Bei der Datenauswertung wurden unterschiedliche prüfstatistische Verfahren eingesetzt (Varianzanalyse, Faktorenanalyse). Die Ergebnisse zeigen, dass es sowohl generelle als auch berufsgruppenspezifische Motive gibt, eine KJP-Ausbildung zu beginnen. Psychologen und (Sozial‐)Pädagogen bewerten ihre im jeweiligen Studium erworbenen KJP-relevanten Kenntnisse und Kompetenzen sehr unterschiedlich. Aus den Ergebnissen werden abschließend einige Empfehlungen hinsichtlich der Zulassungskriterien für die KJP-Ausbildung und die curriculare Entwicklung der zur KJP-Ausbildung berechtigenden Studiengänge abgeleitet.
Carbonate leaching processes in the Red Clay Formation, Chinese Loess Plateau: Fingerprinting East Asian summer monsoon variability during the late Miocene and Pliocene

Published: November 2012

High‐resolution variations in carbonate minerals from the Jiaxian Red Clay section, located at the northern limit of the present East Asian summer monsoon (EASM) on Chinese Loess Plateau were quantified using Fourier transform infrared spectroscopy. We analyzed a large quantity of sediments dated from the late Miocene to Pliocene (8.2–2.6 Ma). The carbonates in this interval show high‐frequency variations alternating between leached and calcareous horizons. The low carbonate contents and high values of magnetic susceptibility and high Rb/Sr ratios were found in the leached zones, a pattern that is consistent with that observed in the overlying Quaternary loess‐paleosol sequences. This pattern suggests that East Asian Monsoon (EAM) rainwater enhanced leaching and accumulation processes of carbonate minerals in the Red Clay Formation in a way similar to the loess‐paleosol sequence. Seven alternating leached and calcareous zones are identified, suggesting oscillations of the EASM and East Asian winter monsoon intervals. The calcareous zones were also found to have high Zr/Rb ratio. These indications of shifts from a strong EASM to East Asian winter monsoon dominance correlate well with the cooling transition indicated by deep sea δ18O isotopes. This evidence suggests that the EAM was active during the late Miocene and Pliocene and was similar to the Quaternary monsoon. The presence of a strong EAM during the Pliocene Warm Period also raises questions about the hypothesis that past and future warm climate conditions could produce a permanent El Niño‐like state.
Subsurface mass transport affects the radioxenon signatures that are used to identify clandestine nuclear tests
Authors: Lowrey J. D. , Biegalski S. R. , Osborne A. G. , Deinert M. R.
Published: November 2012

The ratios of noble gas radioisotopes can provide critical information with which to verify that a belowground nuclear test has taken place. The relative abundance of anthropogenic isotopes is typically assumed to rely solely on their fission yield and decay rate. The xenon signature of a nuclear test is then bounded by the signal from directly produced fission xenon, and by the signal that would come from the addition of xenon from iodine precursors. Here we show that this signal range is too narrowly defined. Transport simulations were done to span the range of geological conditions within the Nevada Test Site. The simulations assume a 1 kt test and the barometric history following the nuclear test at Pahute Mesa in March 1992. Predicted xenon ratios fall outside of the typically assumed range 20% of the time and situations can arise where the ground level signal comes entirely from the decay of iodine precursors.
How stationary is the relationship between Siberian snow and Arctic Oscillation over the 20th century?
Authors: Peings Y. , Brun E. , Mauvais V. , Douville H.
Published: November 2012

Both observational and numerical studies suggest that fall snow cover extent over Eurasia is linked to subsequent winter variations in the predominant Northern Hemisphere teleconnection pattern, known as the Arctic Oscillation (AO). The present study uses the recent 20th Century Reanalysis to explore the snow‐AO relationship over the entire 20th century for the first time. 20th Century Reanalysis is first shown to have a consistently realistic simulation of the onset of the Eurasian snow cover compared to a large number of in situ observations. It is then used to explore the snow‐AO relationship over both the satellite and presatellite periods. Results show that this teleconnection is not stationary and did not emerge until the 1970s. The possible modulation of the teleconnection by the Quasi‐Biennal Oscillation is then discussed, because it could have favored the influence of snow anomalies on the Arctic Oscillation in recent decades. These results have important implications for seasonal forecasting and suggest, in particular, that statistical predictions of the wintertime AO should not be based on snow predictors alone.
