Comparison of musical activities of cochlear implant users with different speech-coding strategies

Speech coding might have an impact on music perception of cochlear implant users. This questionnaire study compares the musical activities and perception of postlingually deafened cochlear implant users with three different coding strategies (CIS, ACE, SPEAK) using the Munich Music Questionnaire. Overall, the self-reported perception of music of CIS, SPEAK, and ACE users did not differ by very much.

Circulating plasma surfactant protein type B as biological marker of alveolar-capillary barrier damage in chronic heart failure

BACKGROUND: Surfactant protein type B (SPB) is needed for alveolar gas exchange. SPB is increased in the plasma of patients with heart failure (HF), with a concentration that is higher when HF severity is highest. The aim of this study was to evaluate the relationship between plasma SPB and both alveolar-capillary diffusion at rest and ventilation versus carbon dioxide production during exercise. METHODS AND RESULTS: Eighty patients with chronic HF and 20 healthy controls were evaluated consecutively, but the required quality for procedures was only reached by 71 patients with HF and 19 healthy controls. Each subject underwent pulmonary function measurements, including lung diffusion for carbon monoxide and membrane diffusion capacity, and maximal cardiopulmonary exercise test. Plasma SPB was measured by immunoblotting. In patients with HF, SPB values were higher (4.5 [11.1] versus 1.6 [2.9], P=0.0006, median and 25th to 75th interquartile), whereas lung diffusion for carbon monoxide (19.7+/-4.5 versus 24.6+/-6.8 mL/mm Hg per min, P<0.0001, mean+/-SD) and membrane diffusion capacity (28.9+/-7.4 versus 38.7+/-14.8, P<0.0001) were lower. Peak oxygen consumption and ventilation/carbon dioxide production slope were 16.2+/-4.3 versus 26.8+/-6.2 mL/kg per min (P<0.0001) and 29.7+/-5.9 and 24.5+/-3.2 (P<0.0001) in HF and controls, respectively. In the HF population, univariate analysis showed a significant relationship between plasma SPB and lung diffusion for carbon monoxide, membrane diffusion capacity, peak oxygen consumption, and ventilation/carbon dioxide production slope (P<0.0001 for all). On multivariable logistic regression analysis, membrane diffusion capacity (beta, -0.54; SE, 0.018; P<0.0001), peak oxygen consumption (beta, -0.53; SE, 0.036; P=0.004), and ventilation/carbon dioxide production slope (beta, 0.25; SE, 0.026; P=0.034) were independently associated with SPB. CONCLUSIONS: Circulating plasma SPB levels are related to alveolar gas diffusion, overall exercise performance, and efficiency of ventilation showing a link between alveolar-capillary barrier damage, gas exchange abnormalities, and exercise performance in HF.

The Diverse Impacts of the Neo-liberal Social Policies on Children’s Welfare and Social Work with Young People: The Finnish Perspective

This article discusses the impacts of globalization, neo-liberal social policies and the Finnish economic recession of the 1990s on children's and young people's welfare. It summarises some of the impacts of Finnish social policies on the everyday lives of families with children and highlights some of the features of the recent and current debates surrounding youth delinquency and the societal reactions to young generations. All this contributes to a contradictory and conflicting societal context which challenges experts in the field of child welfare social work experts to operate - as expected - at the right moment, legally and effectively. Instead of being overly-defensive for the ‘good old’ ways of practicing social work with children, the authors invite social work scholars and practitioners to reconceptualise both the concept of children's citizenship and its position both in child welfare theory and practice in the context of children's global rights.

Scrivere di architettura intorno al 1780: Andrea Memmo e Francesco Milizia tra il Veneto e Roma

Andrea Memmo ist in der Geschichte der Architekturtheorie vor allem deswegen bekannt, weil er durch die Veröffentlichung der 'Elementi d'architettura lodoliana, ossia l'arte del fabricare con solidità scientifica e con eleganza non capricciosa' (Rom 1786) entscheidend dazu beigetragen hat, die originellen architektonischen Konzepte der Nachwelt zu überliefern, die der venezianische Franziskaner Carlo Lodoli zwischen 1730 und 1750 mündlich verbreitet hatte. Der vorliegende Beitrag unternimmt es, anhand des bislang für verloren gehaltenen 'Piano Accademico', den Memmo um 1767 für die venezianische Akademie zum Zwecke der Unterrichtsreform der bildenden Künste (Skulptur, Malerei und Architektur) ausgearbeitet hatte, klarzustellen, welche wichtige Rolle der Aufenthalt in Rom für Memmo gespielt hat. Dies wird auch durch die Briefe belegt, die er während der Ausarbeitung seines Werkes über Lodoli verfasst hatte. Im Rom der 1780er Jahre waren für ihn ausschlaggebend 1. die Beziehungen zur dortigen Accademia di S. Luca und 2. seine Freundschaft zum spanische Botschafter José Nicolas de Azara. Azara hatte ihn dazu ermutigt, über den Padre Lodoli zu schreiben, um dessen Gedanken denen des mit Azara befreundeten Francesco Milizia gegenüberzustellen.

Die einfachen Leute werden für Gerechtigkeit sorgen!: Die deutsch-britischen Verhandlungen über ein Abkommen zur Entschädigung von Opfern nationalsozialistischer Verfolgung, 1956-64

Das Entschädigungsabkommen zwischen der Bundesrepublik Deutschland und Großbritannien von 1964 war eins von insgesamt elf Globalabkommen, die um 1960 zwischen der Bundesrepublik und verschiedenen westeuropäischen Staaten zur Wiedergutmachung nationalsozialistischen Unrechts geschlossen wurden. In der britischen Erinnerungskultur spielten die NS-Verbrechen damals nach wie vor eine große Rolle. Breite Teile der Öffentlichkeit – mobilisiert durch Presse und Wohlfahrtsorganisationen – verfolgten die Verhandlungen und kritisierten die Haltung vor allem der deutschen, aber auch der britischen Regierung. Strittig war besonders die Frage, welche Opferkategorien in das Abkommen miteinbezogen werden sollten. Dies betraf vor allem staatenlose Verfolgte, die erst nach Kriegsende die britische Staatsbürgerschaft erhalten hatten. Während Großbritannien die Berücksichtigung dieser Gruppe forderte, verwies die Bundesregierung auf den UN-Fonds für staatenlose Opfer. 1964 zahlte die Bundesrepublik schließlich eine Pauschalsumme an Großbritannien, über deren Verteilung die britische Regierung selbst bestimmen konnte.

Laribacter hongkongensis: a potential cause of infectious diarrhea

In this study, we describe the isolation of Laribacter hongkongensis, a recently described genus and species of bacterium, in pure culture on charcoal cefoperazone deoxycholate agar from the stool of six patients with diarrhea. Three patients were residents of Hong Kong, and three of Switzerland. In none of the stool samples obtained from these six patients was Salmonella, Shigella, enterohemorrhagic Escherichia coli, Vibrio, Aeromonas, Plesiomonas, or Campylobacter recovered. Rotavirus antigen detection, electron microscopic examination for viruses, and microscopic examinations for ova and cysts were all negative for the stool samples obtained from the three patients in Hong Kong. Enterotoxigenic E. coli was recovered from one of the patients in Hong Kong. Unlike L. hongkongensis type strain HKU1, all the six strains were motile with bipolar flagellae. Sequencing of the 16S ribosomal RNA genes of the six strains showed that they all had sequences with only 0-2 base differences to that of the type strain. Pulsed field gel electrophoresis of the SpeI digested genomic DNA of the six isolates and that of the type strain revealed that the seven isolates were genotypically unrelated strains. More extensive epidemiologic studies should be carried out to ascertain the causative association between L. hongkongensis and diarrhea and to define the reservoir and modes of transmission of L. hongkongensis.

The small SLC43 family: facilitator system l amino acid transporters and the orphan EEG1

The SLC43 family is composed of only three genes coding for the plasma membrane facilitator system l amino acid transporters LAT3 (SLC43A1; TC 2.A.1.44.1) and LAT4 (SLC43A2; TC 2.A.1.44.2), and the orphan protein EEG1 (SLC43A3; TC 2.A.1.44.3). Besides the known mechanism of transport of LAT3 and LAT4, their physiological roles still remain quite obscure. Morphants suggested a role of LAT3 in renal podocyte development in zebrafish. Expression in liver and skeletal muscle, and up-regulation by starvation suggest a role of LAT3 in the flux of branched-chain amino acids (BCAAs) from liver and skeletal muscle to the bloodstream. Finally, LAT3 is up-regulated in androgen-dependent cancers, suggesting a role in mTORC1 signaling in this type of tumors. In addition, LAT4 might contribute to the transfer of BCAAs from mother to fetus. Unfortunately, the EEG1 mouse model (EEG1(Y221∗)) described here has not yet offered a clue to the physiological role of this orphan protein.

A Gly98Val mutation in the N-Myc downstream regulated gene 1 (NDRG1) in Alaskan Malamutes with polyneuropathy.

The first cases of early-onset progressive polyneuropathy appeared in the Alaskan Malamute population in Norway in the late 1970s. Affected dogs were of both sexes and were ambulatory paraparetic, progressing to non-ambulatory tetraparesis. On neurologic examination, affected dogs displayed predominantly laryngeal paresis, decreased postural reactions, decreased spinal reflexes and muscle atrophy. The disease was considered eradicated through breeding programmes but recently new cases have occurred in the Nordic countries and the USA. The N-myc downstream-regulated gene (NDRG1) is implicated in neuropathies with comparable symptoms or clinical signs both in humans and in Greyhound dogs. This gene was therefore considered a candidate gene for the polyneuropathy in Alaskan Malamutes. The coding sequence of the NDRG1 gene derived from one healthy and one affected Alaskan Malamute revealed a non-synonymous G>T mutation in exon 4 in the affected dog that causes a Gly98Val amino acid substitution. This substitution was categorized to be "probably damaging" to the protein function by PolyPhen2 (score: 1.000). Subsequently, 102 Alaskan Malamutes from the Nordic countries and the USA known to be either affected (n = 22), obligate carriers (n = 7) or healthy (n = 73) were genotyped for the SNP using TaqMan. All affected dogs had the T/T genotype, the obligate carriers had the G/T genotype and the healthy dogs had the G/G genotype except for 13 who had the G/T genotype. A protein alignment showed that residue 98 is conserved in mammals and also that the entire NDRG1 protein is highly conserved (94.7%) in mammals. We conclude that the G>T substitution is most likely the mutation that causes polyneuropathy in Alaskan Malamutes. Our characterization of a novel candidate causative mutation for polyneuropathy offers a new canine model that can provide further insight into pathobiology and therapy of human polyneuropathy. Furthermore, selection against this mutation can now be used to eliminate the disease in Alaskan Malamutes.

Concept, design and implementation of a cardiovascular gene-centric 50 k SNP array for large-scale genomic association studies.

A wealth of genetic associations for cardiovascular and metabolic phenotypes in humans has been accumulating over the last decade, in particular a large number of loci derived from recent genome wide association studies (GWAS). True complex disease-associated loci often exert modest effects, so their delineation currently requires integration of diverse phenotypic data from large studies to ensure robust meta-analyses. We have designed a gene-centric 50 K single nucleotide polymorphism (SNP) array to assess potentially relevant loci across a range of cardiovascular, metabolic and inflammatory syndromes. The array utilizes a "cosmopolitan" tagging approach to capture the genetic diversity across approximately 2,000 loci in populations represented in the HapMap and SeattleSNPs projects. The array content is informed by GWAS of vascular and inflammatory disease, expression quantitative trait loci implicated in atherosclerosis, pathway based approaches and comprehensive literature searching. The custom flexibility of the array platform facilitated interrogation of loci at differing stringencies, according to a gene prioritization strategy that allows saturation of high priority loci with a greater density of markers than the existing GWAS tools, particularly in African HapMap samples. We also demonstrate that the IBC array can be used to complement GWAS, increasing coverage in high priority CVD-related loci across all major HapMap populations. DNA from over 200,000 extensively phenotyped individuals will be genotyped with this array with a significant portion of the generated data being released into the academic domain facilitating in silico replication attempts, analyses of rare variants and cross-cohort meta-analyses in diverse populations. These datasets will also facilitate more robust secondary analyses, such as explorations with alternative genetic models, epistasis and gene-environment interactions.

Fluktuierende Kopfschmerzen und Wesensveränderung bei einem 63-jährigen Patienten

We present a 63 year old man with new onset of fluctuating headache and behavioural changes showing marked inhibition and disorientation. After non invasive and invasive diagnostics an isolated cerebral vasculitis was found. Key results have been found in cerebral MRI and cerebral digital subtraction angiography with irregularities of vessel calibre of the intracerebral arteries. During treatment with high-dose corticosteroid therapy and Cyclophosphamid pulse therapy qualitative disorders and headache rapidly regressed. We discuss differential diagnosis of secondary headache, etiology of cerebral vasculitides, diagnostic challenge and therapy in isolated cerebral vasculitis.
