Efficacy and safety of intravenous meropenem and tobramycin versus ceftazidime and tobramycin in cystic fibrosis

BACKGROUND: Cystic fibrosis (CF) is characterized by chronic bacterial broncho-pulmonary infection. Although intravenous (IV) antibiotic therapy is regarded as standard treatment in CF, only few randomised trials comparing different antibiotic compounds exist. METHODS: We report on a prospective multicenter interventional trial of IV meropenem (120 mg/kg/day) or IV ceftazidime (200-400 mg/kg/day), each administered together with IV tobramycin (9-12 mg/kg/day). Outcome measures were changes in lung function, microbiological sputum burden and blood inflammatory marker. Liver and renal function values were measured to assess safety. RESULTS: One hundred eighteen patients (59/59) were included into the study with the following indications: first infection of P. aeruginosa (n=6), acute pulmonary exacerbation (n=34) and suppression therapy of chronic P. aeruginosa colonization (n=78). Both treatments improved lung function measures, bacterial sputum burden and CRP levels with no differences between treatment groups observed. A significant higher elevation for alkaline phosphatase (p<0.0001) was observed for patients in the meropenem/tobramycin group. CONCLUSIONS: IV antibiotic therapy in CF patients with meropenem/tobramycin is as effective as with ceftazidime/tobramycin regarding lung function, microbiological sputum burden and systemic inflammatory status. Hepato-biliary function should be monitored carefully during IV treatment, possibly important in CF patients with pre-existing liver disease.

Architektura a ideologie. Výchovné instituce Adolfa Hitlera v protektorátu Čechy a Morava a v Říšské župě Sudety

This article examines the architecture of the Nazi regime in two occupied cities of Czechoslovakia, Praha/Prag and Jihlava/Iglau (the latter being one of the traditionally German-speaking island in the bohemia country), and focuses specifically on the process by which Hitler youth organisations (Hitlerjugend) in case of ‘education’ and indoctrination of youth were or were not successfully established in these cities. As comparison, he takes the political-administrative centres of the Sudeten Reichsgau, Ústí/Aussig, Opava/Troppau, Karlovy Vary/Karlsbad and Liberec/Reichenberg. Drawing on Czech and German archive materials, the extensive body of modern analytical literature, and propagandist literature from the period studied, the author examines the extent to which architecture served as a projection screen for Fascist propaganda in the Occupied Eastern territories. He describes the role played by the Reichsstelle für Raumordnung and shows how the Reich’s propagandist objectives came to be reflected in a high specific typology and stylistic lexicon/configuration for the architecture of Hitler youth hostels and homes He examines the process by which these organisations were powerful implanted into the space of occupied Czechoslovakia (and Sudeten) too, a topic that has not yet been addressed in (art) history too. The building projects developed for the Protectorate (published here for the first time) and managed by the Reich’s Hitler Youth Leadership in Berlin (Kulturamt, Reichsjugendführung, RJF, Abteilung HJ) reveal the ties that existed between the construction authorities in the Reich and the Protectorate, including the Planning Committee for the City of Prague. The author asks how many German and Czech architects participated for their own profit in the Nazi system, and for future research raises the hitherto taboo question of guilt and collaboration with the Nazis and the perception of this phenomenon in art history, i.e. the measure of active cooperation of not just German but also Czech architects who contributed to the planning and implementation of projects and thereby unequivocally had a hand in consolidating the totalitarian regime and de facto in the forced „Germanification” of their own people under occupation.

Vegetation and fire history of coastal north-eastern Sardinia (Italy) under changing Holocene climates and land use

Little is known about the vegetation and fire history of Sardinia, and especially the long-term history of the thermo-Mediterranean belt that encompasses its entire coastal lowlands. A new sedimentary record from a coastal lake based on pollen, spores, macrofossils and microscopic charcoal analysis is used to reconstruct the vegetation and fire history in north-eastern Sardinia. During the mid-Holocene (c. 8,100–5,300 cal bp), the vegetation around Stagno di Sa Curcurica was characterised by dense Erica scoparia and E. arborea stands, which were favoured by high fire activity. Fire incidence declined and evergreen broadleaved forests of Quercus ilex expanded at the beginning of the late Holocene. We relate the observed vegetation and fire dynamics to climatic change, specifically moister and cooler summers and drier and milder winters after 5,300 cal bp. Agricultural activities occurred since the Neolithic and intensified after c. 7,000 cal bp. Around 2,750 cal bp, a further decline of fire incidence and Erica communities occurred, while Quercus ilex expanded and open-land communities became more abundant. This vegetation shift coincided with the historically documented beginning of Phoenician period, which was followed by Punic and Roman civilizations in Sardinia. The vegetational change at around 2,750 cal bp was possibly advantaged by a further shift to moister and cooler summers and drier and milder winters. Triggers for climate changes at 5,300 and 2,750 cal bp may have been gradual, orbitally-induced changes in summer and winter insolation, as well as centennial-scale atmospheric reorganizations. Open evergreen broadleaved forests persisted until the twentieth century, when they were partly substituted by widespread artificial pine plantations. Our results imply that highly flammable Erica vegetation, as reconstructed for the mid-Holocene, could re-emerge as a dominant vegetation type due to increasing drought and fire, as anticipated under global change conditions.
