    Diese Diplomarbeit mit dem Titel „Entwicklung durch HĂ€user? Kann Entwicklung geschenkt werden?“ beschĂ€ftigt sich mit dem brasilianischen Sozialwohnbau als Beispiel fĂŒr Entwicklungshilfe – und Zusammenarbeit. Im Fokus steht das Fallbeispiel der Siedlung Conjunto VitĂłria im Nordosten Brasiliens, welche mit den Theorien des Wissenschaftlers James Fergusons untersucht werden soll. Im vergangenen Jahrhundert versuchte die brasilianische Regierung durch verschiedenste Maßnahmen das Problem der unterentwickelten, subhumanen Gebieten Namens Favelas aus den StĂ€dten zu verbannen. Dies geschah jedoch mit wenig erfolgreichen Konsequenzen. Durch eine kurze Ausarbeitung der Annahmen und Thesen des Post- Developments und der genauen Auseinandersetzung mit den Werken James Fergusons kann das Aufkommen der Probleme innerhalb der staatlichen Maßnahmen im Bereich des Wohnwesens bzw. der Entwicklungspolitiken etwas differenzierter und reflektierter betrachtet werden. Nach der ErlĂ€uterung relevanter Konzepte und historischer Ereignisse des brasilianischen Sozialwohnbaus sollen erste Strukturen und Mechanismen des Entwicklungsdiskurses anhand der brasilianischen Politik erkannt werden, um diese spĂ€ter durch Interviews am Fallbeispiel zu erforschen. Ziel der Arbeit ist es die Schwierigkeiten innerhalb der Entwicklungspolitik am Beispiel des brasilianischen Sozialwohnbaus zu erarbeiten, um damit spĂ€ter die Fragestellung „Warum kann Entwicklung nicht fĂŒr alle Menschen eintreten?“ beantworten zu können.This thesis with ist title „Entwicklung durch HĂ€user? Kann Entwicklung geschenkt werden?“ deals with the brazilian housing politics as an example for aid development or co-operation. Its focus lies on the case study of the residential area Conjunto VitĂłria in the Northeast of Brazil. During the last century the brazilian government attempted to combat the problem of undeveloped, degrading urban areas named Favelas with different interventions. This resulted with few favourable consequences. With a short discussion about the ideas and thesis of the Post- Development studies and an acurate debate of James Ferguson’s books it is possible to have a different and more reflective view on the problems of the governmental interventions of housing and development politics. After an explanation of relevant concepts and historic events of the brazilian housing politics it should be possible to note the structures and mechanism of the development discourse to verify this results afterwards on the case study. The main goal of this thesis is to analyse the difficulties of develpment politics on the case of the brazilian housing politics to answer afterwards the main question of this paper: “Why is development for everybody impossible?

    Clonal hematopoiesis as a pitfall in germline variant interpretation in the context of Mendelian disorders

    Clonal hematopoiesis because of somatic mutations in hematopoietic stem/progenitor cells is an age-related phenomenon and commonly observed when sequencing blood DNA in elderly individuals. Several genes that are implicated in clonal hematopoiesis are also associated with Mendelian disorders when mutated in the germline, potentially leading to variant misinterpretation. We performed a literature search to identify genes associated with age-related clonal hematopoiesis followed by an OMIM query to identify the subset of genes in which germline variants are associated with Mendelian disorders. We retrospectively screened for diagnostic cases in which the presence of age-related clonal hematopoiesis confounded exome sequencing data interpretation. We found 58 genes in which somatic mutations are implicated in clonal hematopoiesis, while germline variants in the same genes are associated with Mendelian (mostly neurodevelopmental) disorders. Using five selected cases of individuals with suspected monogenic disorders, we illustrate how clonal hematopoiesis in either variant databases or exome sequencing datasets poses a pitfall, potentially leading to variant misclassification and erroneous conclusions regarding gene-disease associations

    Profiling endogenous adrenal function during veno-venous ECMO support in COVID-19 ARDS: a descriptive analysis

    BackgroundProlonged critical illness is often accompanied by an impairment of adrenal function, which has been frequently related to conditions complicating patient management. The presumed connection between hypoxia and the pathogenesis of this critical- illness- related corticosteroid insufficiency (CIRCI) might play an important role in patients with severe acute respiratory distress syndrome (ARDS). Since extracorporeal membrane oxygenation (ECMO) is frequently used in ARDS, but data on CIRCI during this condition are scarce, this study reports the behaviour of adrenal function parameters during oxygenation support with veno-venous (vv)ECMO in coronavirus disease 2019 (COVID-19) ARDS.MethodsA total of 11 patients undergoing vvECMO due to COVID-19 ARDS at the Medical University of Vienna, who received no concurrent corticosteroid therapy, were retrospectively included in this study. We analysed the concentrations of cortisol, aldosterone, and angiotensin (Ang) metabolites (Ang I–IV, Ang 1–7, and Ang 1–5) in serum via liquid chromatography/tandem mass spectrometry before, after 1 day, 1 week, and 2 weeks during vvECMO support and conducted correlation analyses between cortisol and parameters of disease severity.ResultsCortisol concentrations appeared to be lowest after initiation of ECMO and progressively increased throughout the study period. Higher concentrations were related to disease severity and correlated markedly with interleukin-6, procalcitonin, pH, base excess, and albumin during the first day of ECMO. Fair correlations during the first day could be observed with calcium, duration of critical illness, and ECMO gas flow. Angiotensin metabolite concentrations were available in a subset of patients and indicated a more homogenous aldosterone response to plasma renin activity after 1 week of ECMO support.ConclusionOxygenation support through vvECMO may lead to a partial recovery of adrenal function over time. In homogenous patient collectives, this novel approach might help to further determine the importance of adrenal stress response in ECMO and the influence of oxygenation support on CIRCI

    Monogenic variants in dystonia: an exome-wide sequencing study

    Background Dystonia is a clinically and genetically heterogeneous condition that occurs in isolation (isolated dystonia), in combination with other movement disorders (combined dystonia), or in the context of multisymptomatic phenotypes (isolated or combined dystonia with other neurological involvement). However, our understanding of its aetiology is still incomplete. We aimed to elucidate the monogenic causes for the major clinical categories of dystonia. Methods For this exome-wide sequencing study, study participants were identified at 33 movement-disorder and neuropaediatric specialty centres in Austria, Czech Republic, France, Germany, Poland, Slovakia, and Switzerland. Each individual with dystonia was diagnosed in accordance with the dystonia consensus definition. Index cases were eligible for this study if they had no previous genetic diagnosis and no indication of an acquired cause of their illness. The second criterion was not applied to a subset of participants with a working clinical diagnosis of dystonic cerebral palsy. Genomic DNA was extracted from blood of participants and whole-exome sequenced. To find causative variants in known disorder-associated genes, all variants were filtered, and unreported variants were classified according to American College of Medical Genetics and Genomics guidelines. All considered variants were reviewed in expert round-table sessions to validate their clinical significance. Variants that survived filtering and interpretation procedures were defined as diagnostic variants. In the cases that went undiagnosed, candidate dystonia-causing genes were prioritised in a stepwise workflow. Findings We sequenced the exomes of 764 individuals with dystonia and 346 healthy parents who were recruited between June 1, 2015, and July 31, 2019. We identified causative or probable causative variants in 135 (19%) of 728 families, involving 78 distinct monogenic disorders. We observed a larger proportion of individuals with diagnostic variants in those with dystonia (either isolated or combined) with coexisting non-movement disorder-related neurological symptoms (100 [45%] of 222;excepting cases with evidence of perinatal brain injury) than in those with combined (19 [19%] of 98) or isolated (16 [4%] of 388) dystonia. Across all categories of dystonia, 104 (65%) of the 160 detected variants affected genes which are associated with neurodevelopmental disorders. We found diagnostic variants in 11 genes not previously linked to dystonia, and propose a predictive clinical score that could guide the implementation of exome sequencing in routine diagnostics. In cases without perinatal sentinel events, genomic alterations contributed substantively to the diagnosis of dystonic cerebral palsy. In 15 families, we delineated 12 candidate genes. These include IMPDH2, encoding a key purine biosynthetic enzyme, for which robust evidence existed for its involvement in a neurodevelopmental disorder with dystonia. We identified six variants in IMPDH2, collected from four independent cohorts, that were predicted to be deleterious de-novo variants and expected to result in deregulation of purine metabolism. Interpretation In this study, we have determined the role of monogenic variants across the range of dystonic disorders, providing guidance for the introduction of personalised care strategies and fostering follow-up pathophysiological explorations

    was previously implicated in periventricular nodular heterotopia (PVNH) in only five individuals and systematic clinical characterisation was not available. The aim of this study is to provide a comprehensive description of the phenotypic and genotypic spectrum of -related neurodevelopmental disorder. We collected detailed phenotypes of an international cohort of individuals (n=17) with variants assembled through the GeneMatcher platform. Missense variants were structurally modelled, and the impact of several were functionally validated. De novo variants (10 missense, 1 frameshift, 1 splice altering resulting in 9 residues insertion) in were identified among 17 unrelated individuals. Detailed phenotypes included intellectual disability (ID), microcephaly, seizures and PVNH. No specific facial characteristics were consistent across all cases, however microretrognathia was common. Various hearing and visual defects were recurrent, and interestingly, some inflammatory features were reported. MRI of the brain frequently showed abnormalities consistent with a neuronal migration disorder. We confirm the role of in an autosomal dominant syndrome with a phenotypic spectrum including severe ID, microcephaly, seizures and PVNH due to impaired neuronal migration
