    Die Diagnose einer Aufmerksamkeitsdefizit- bzw. Hyperaktivitätsstörung (ADHS) ist wohl die kinderpsychiatrische "Erfolgsgeschichte" des letzten Jahrzehnts. Im vorliegenden Beitrag beschäftigen wir uns mit der Situation "betroffener" Eltern und gehen dabei insbesondere der Frage nach, warum diese das Deutungsangebot ADHS ohne weiteres akzeptieren, ja oft nachgerade darum anstehen. Die hier vorgestellten Ergebnisse einer kritischen Diskursanalyse eines ADHS-Internetforums geben dazu Einblicke in die Lebenswelten der Eltern und zeigen, dass diese das Deutungsangebot ADHS im Kontext gesellschaftlich geforderter Erziehungserwartungen, über die Akzeptanz der Diagnose zugänglich werdender Hilfsangebote und nicht zuletzt auf Grund der damit einhergehende eigenen "Entschuldung" nur schwer ausschlagen können.In the last decade, the diagnosis of an attention deficit hyperactivity disorder (ADHD) has probably been the success story within child psychiatry. This article deals with the situation of 'concerned' parents and asks why they so readily accept the diagnosis, if not well-nigh queue up for it. To address this question, we present results of a critical discourse analysis that we conducted for a highly frequented German ADHS-internet forum. They indicate that, in the context of pervasive societal expectations and demands pertaining to child rearing and education, parents can hardly reject psychiatry's new gift. In particular, this has to do with institutional offers that go along with the diagnosis and promise life-world relief for the parents and, in the symbolic realm, with a - medically sanctioned - opportunity for their own exculpation

    CONAN: copy number variation analysis software for genome-wide association studies

    <p>Abstract</p> <p>Background</p> <p>Genome-wide association studies (GWAS) based on single nucleotide polymorphisms (SNPs) revolutionized our perception of the genetic regulation of complex traits and diseases. Copy number variations (CNVs) promise to shed additional light on the genetic basis of monogenic as well as complex diseases and phenotypes. Indeed, the number of detected associations between CNVs and certain phenotypes are constantly increasing. However, while several software packages support the determination of CNVs from SNP chip data, the downstream statistical inference of CNV-phenotype associations is still subject to complicated and inefficient in-house solutions, thus strongly limiting the performance of GWAS based on CNVs.</p> <p>Results</p> <p>CONAN is a freely available client-server software solution which provides an intuitive graphical user interface for categorizing, analyzing and associating CNVs with phenotypes. Moreover, CONAN assists the evaluation process by visualizing detected associations via Manhattan plots in order to enable a rapid identification of genome-wide significant CNV regions. Various file formats including the information on CNVs in population samples are supported as input data.</p> <p>Conclusions</p> <p>CONAN facilitates the performance of GWAS based on CNVs and the visual analysis of calculated results. CONAN provides a rapid, valid and straightforward software solution to identify genetic variation underlying the 'missing' heritability for complex traits that remains unexplained by recent GWAS.

    Unmanned aircraft systems as a new source of disturbance for wildlife: A systematic review.

    The use of small Unmanned Aircraft Systems (UAS; also known as "drones") for professional and personal-leisure use is increasing enormously. UAS operate at low altitudes (<500 m) and in any terrain, thus they are susceptible to interact with local fauna, generating a new type of anthropogenic disturbance that has not been systematically evaluated. To address this gap, we performed a review of the existent literature about animals' responses to UAS flights and conducted a pooled analysis of the data to determine the probability and intensity of the disturbance, and to identify the factors influencing animals' reactions towards the small aircraft. We found that wildlife reactions depended on both the UAS attributes (flight pattern, engine type and size of aircraft) and the characteristics of animals themselves (type of animal, life-history stage and level of aggregation). Target-oriented flight patterns, larger UAS sizes, and fuel-powered (noisier) engines evoked the strongest reactions in wildlife. Animals during the non-breeding period and in large groups were more likely to show behavioral reactions to UAS, and birds are more prone to react than other taxa. We discuss the implications of these results in the context of wildlife disturbance and suggest guidelines for conservationists, users and manufacturers to minimize the impact of UAS. In addition, we propose that the legal framework needs to be adapted so that appropriate actions can be undertaken when wildlife is negatively affected by these emergent practices

    The Beaker phenomenon and the genomic transformation of northwest Europe

    From around 2750 to 2500 bc, Bell Beaker pottery became widespread across western and central Europe, before it disappeared between 2200 and 1800 bc. The forces that propelled its expansion are a matter of long-standing debate, and there is support for both cultural diffusion and migration having a role in this process. Here we present genome-wide data from 400 Neolithic, Copper Age and Bronze Age Europeans, including 226 individuals associated with Beaker-complex artefacts. We detected limited genetic affinity between Beaker-complex-associated individuals from Iberia and central Europe, and thus exclude migration as an important mechanism of spread between these two regions. However, migration had a key role in the further dissemination of the Beaker complex. We document this phenomenon most clearly in Britain, where the spread of the Beaker complex introduced high levels of steppe-related ancestry and was associated with the replacement of approximately 90% of Britain’s gene pool within a few hundred years, continuing the east-to-west expansion that had brought steppe-related ancestry into central and northern Europe over the previous centuries

    Differential prognostic utility of adiposity measures in chronic kidney disease

    Objective Adipose tissue contributes to adverse outcomes in chronic kidney disease (CKD), but there is uncertainty regarding the prognostic relevance of different adiposity measures. We analyzed the associations of neck circumference (NC), waist circumference (WC), and body mass index (BMI) with clinical outcomes in patients with mild to severe CKD. Methods The German Chronic Kidney Disease (GCKD) study is a prospective cohort study, which enrolled Caucasian adults with mild to severe CKD, defined as estimated glomerular filtration rate (eGFR): 30–60 mL/min/1.73 m2, or >60 mL/min/1.73 m2 in the presence of overt proteinuria. Associations of NC, WC and BMI with all-cause death, major cardiovascular events (MACE: a composite of non-fatal stroke, non-fatal myocardial infarction, peripheral artery disease intervention, and cardiovascular death), kidney failure (a composite of dialysis or transplantation) were analyzed using multivariable Cox proportional hazards regression models adjusted for confounders and the Akaike information criteria (AIC) were calculated. Models included sex interactions with adiposity measures. Results A total of 4537 participants (59% male) were included in the analysis. During a 6.5-year follow-up, 339 participants died, 510 experienced MACE, and 341 developed kidney failure. In fully adjusted models, NC was associated with all-cause death in women (HR 1.080 per cm; 95% CI 1.009–1.155), but not in men. Irrespective of sex, WC was associated with all-cause death (HR 1.014 per cm; 95% CI 1.005–1.038). NC and WC showed no association with MACE or kidney failure. BMI was not associated with any of the analyzed outcomes. Models of all-cause death including WC offered the best (lowest) AIC. Conclusion In Caucasian patients with mild to severe CKD, higher NC (in women) and WC were significantly associated with increased risk of death from any cause, but BMI was not

    Preparation of Novel Enantiopure Ferrocenyl-Based Ligands for Asymmetric Catalysis

    Get PDF
    Novel enantiopure ferrocene-based aminophosphine and diphosphine ligands for asymmetric catalysts have been developed. In all cases a highly flexible synthetic approach allowed access to ligands with different ferrocenyl backbones and with a variety of functional group patterns. Procedures for the synthesis of six families of ligands with either a homo- or heteroannularly bridged ferrocene, ferrocenylmethyl, biferrocene, biferroceno-azepine or ferrocenyl-aryl framework are described in detail
