BACKGROUND: There are differences in the literature regarding outcomes of premature small-for-gestational-age (SGA) and appropriate-for gestational-age (AGA) infants, possibly due to failure to take into account gestational age at birth. OBJECTIVE: To compare mortality and respiratory morbidity of SGA and AGA premature newborn infants. DESIGN/METHODS: A retrospective study was done of the 2,487 infants born without congenital anomalies at RESULTS: Controlling for GA, premature SGA infants were at a higher risk for mortality (Odds ratio 3.1, P = 0.001) and at lower risk of respiratory distress syndrome (OR = 0.71, p = 0.02) than AGA infants. However multivariate logistic regression modeling found that the odds of having respiratory distress syndrome (RDS) varied between SGA and AGA infants by GA. There was no change in RDS risk in SGA infants at GA 32 wk (OR = 0.41, 95% CI 0.27 - 0.63; p < 0.01). After controlling for GA, SGA infants were observed to be at a significantly higher risk for developing chronic lung disease as compared to AGA infants (OR = 2.2, 95% CI = 1.2 - 3.9, P = 0.01). There was no significant difference between SGA and AGA infants in total days on ventilator. Among infants who survived, mean length of hospital stay was significantly higher in SGA infants born between 26-36 wks GA than AGA infants. CONCLUSIONS: Premature SGA infants have significantly higher mortality, significantly higher risk of developing chronic lung disease and longer hospital stay as compared to premature AGA infants. Even the reduced risk of RDS in infants born at >/=32 wk GA, (conferred possibly by intra-uterine stress leading to accelerated lung maturation) appears to be of transient effect and is counterbalanced by adverse effects of poor intrauterine growth on long term pulmonary outcomes such as chronic lung disease.

Die gegenwärtigen Bemühungen für ein umfassendes Handels- und Investitionsschutzabkommen zwischen der EU und den USA werden nicht ohne Auswirkungen auf die Schweiz bleiben. Eine Studie des World Trade Institute der Universität Bern im Auftrag des Staatssekretariats für Wirtschaft analysiert die möglichen Auswirkungen eines Abkommens auf die Schweizer Wirtschaft und auf die Handelsbeziehungen der Schweiz. Unterschiedliche Szenarien führen dabei zu unterschiedlichen Auswirkungen.

On 9 February 2014, the Swiss people accepted the popular initiative “against mass immigration” launched by the national-conservative Swiss People’s Party (SVP). This voting outcome has triggered wide-ranging debates about both the policy on immigrants as well as the future of Switzerland within the European context. Against this background, we evaluate attitudes toward immigration in Switzerland. Using hitherto unexplored survey data of MOSAiCH, our empirical analyses show that already in the year 2013, before the debate about the initiative on mass immigration was in full swing, roughly 53 percent of the 1011 interviewed Swiss citizens stated that immigration should be reduced. Moreover, our estimations indicate that the threats and fears induced by immigration and the will to maintain sovereignty and autonomy are particularly relevant for attitudes toward immigration. By contrast, education and national or personal economic conditions are only weakly related to the immigration issue.

Wahlsysteme prägen entscheidend den Charakter eines politischen Systems. Durch sie werden die politischen Präferenzen der Wähler in Mandate für die Repräsentationsorgane wie den Nationalrat übersetzt. Die Gestaltung des Wahlsystems ist damit auch immer eine zentrale Machtfrage, die darüber entscheidet, welche politischen Gruppierungen die Parlamentsmehrheit stellen und welche in der Minderheit sind. Der Artikel sucht nach Antworten auf folgende Fragen: Wie wirkt sich das schweizerische Wahlsystem auf den Erfolg der Parteien bei den Nationalratswahlen aus? Ist eine Systemreform angezeigt?

Der längerfristige Erfolg auf dem Arbeitsmarkt hängt nicht zuletzt vom erlernten Beruf ab. Generell haben Absolventen einer beruflichen Grundbildung deutlich bessere Chancen auf dem Arbeitsmarkt als ungelernte Arbeitskräfte. Aber nicht jede Berufslehre bietet dieselbe Garantie für einen erfolgreichen Erwerbsverlauf. Eine neue Studie des Stellenmarktmonitors Schweiz liefert dazu erstmals informative Kennzahlen. Es lassen sich Berufsfelder mit über- und unterdurchschnittlichen Perspektiven unterscheiden, aber auch solche mit konjunkturell stark schwankenden oder ausgesprochen uneinheitlichen Aussichten auf dem Arbeitsmarkt.

Eosinophils are white blood cells that function in innate immunity and participate in the pathogenesis of various inflammatory and neoplastic disorders. Their secretory granules contain four cytotoxic proteins, including the eosinophil major basic protein (MBP-1). How MBP-1 toxicity is controlled within the eosinophil itself and activated upon extracellular release is unknown. Here we show how intragranular MBP-1 nanocrystals restrain toxicity, enabling its safe storage, and characterize them with an X-ray-free electron laser. Following eosinophil activation, MBP-1 toxicity is triggered by granule acidification, followed by extracellular aggregation, which mediates the damage to pathogens and host cells. Larger non-toxic amyloid plaques are also present in tissues of eosinophilic patients in a feedback mechanism that likely limits tissue damage under pathological conditions of MBP-1 oversecretion. Our results suggest that MBP-1 aggregation is important for innate immunity and immunopathology mediated by eosinophils and clarify how its polymorphic self-association pathways regulate toxicity intra- and extracellularly.

BACKGROUND Deep brain stimulation (DBS) is recognized as an effective treatment for movement disorders. We recently changed our technique, limiting the number of brain penetrations to three per side. OBJECTIVES The first aim was to evaluate the electrode precision on both sides of surgery since we implemented this surgical technique. The second aim was to analyse whether or not the electrode placement was improved with microrecording and macrostimulation. METHODS We retrospectively reviewed operation protocols and MRIs of 30 patients who underwent bilateral DBS. For microrecording and macrostimulation, we used three parallel channels of the 'Ben Gun' centred on the MRI-planned target. Pre- and post-operative MRIs were merged. The distance between the planned target and the centre of the implanted electrode artefact was measured. RESULTS There was no significant difference in targeting precision on both sides of surgery. There was more intra-operative adjustment of the second electrode positioning based on microrecording and macrostimulation, which allowed to significantly approach the MRI-planned target on the medial-lateral axis. CONCLUSION There was more electrode adjustment needed on the second side, possibly in relation with brain shift. We thus suggest performing a single central track with electrophysiological and clinical assessment, with multidirectional exploration on demand for suboptimal clinical responses.
