Effects of cardiology review of the electrocardiogram in patients with suspected acute coronary syndromes

Misclassification of the electrocardiogram (ECG) contributes to treatment errors in patients with acute coronary syndrome. We hypothesized that cardiology ECG review could reduce these errors.

Suitability of real-time quantitative PCR to estimate the relative telomere length in European Hake (Merluccius merluccius Linnaeus, 1758)

Telomere length measurement has been proposed as a promising tool to estimate the age of individuals in natural populations. We used real-time quantitative PCR (qPCR) to measure relative telomere length in four tissues (brain, kidney, liver and muscle) of European hake (Merluccius merluccius) in different groups based upon body length an otolith age estimate. We observed a high level of inter-individual differences in the measurements of relative telomere length in hakes of similar age and body length groups. The results of qPCR analysis showed a great variability in all measures and a lack of repeatability and reproducibility with significant statistical differences in the results of the different assays. The paper discusses the technical reasons for the variability in qPCR obtained in this work and by other authors.

Rivastigmine for the prevention of postoperative delirium in elderly patients undergoing elective cardiac surgery--a randomized controlled trial

OBJECTIVE: Cardiac surgery is frequently followed by postoperative delirium, which is associated with increased 1-year mortality, late cognitive deficits, and higher costs. Currently, there are no recommendations for pharmacologic prevention of postoperative delirium. Impaired cholinergic transmission is believed to play an important role in the development of delirium. We tested the hypothesis that prophylactic short-term administration of oral rivastigmine, a cholinesterase inhibitor, reduces the incidence of delirium in elderly patients during the first 6 days after elective cardiac surgery. DESIGN:: Double-blind, randomized, placebo-controlled trial. SETTING: One Swiss University Hospital. PATIENTS: One hundred twenty patients aged 65 or older undergoing elective cardiac surgery with cardiopulmonary bypass. INTERVENTION: Patients were randomly assigned to receive either placebo or 3 doses of 1.5 mg of oral rivastigmine per day starting the evening before surgery and continuing until the evening of the sixth postoperative day. MEASUREMENTS AND MAIN RESULTS: The primary predefined outcome was delirium diagnosed with the Confusion Assessment Method within 6 days postoperatively. Secondary outcome measures were the results of daily Mini-Mental State Examinations and clock drawing tests, and the use of a rescue treatment consisting of haloperidol and/or lorazepam in patients with delirium. Delirium developed in 17 of 57 (30%) and 18 of 56 (32%) patients in the placebo and rivastigmine groups, respectively (p = 0.8). There was no treatment effect on the time course of Mini-Mental State Examinations and clock drawing tests (p = 0.4 and p = 0.8, respectively). There was no significant difference in the number of patients receiving haloperidol (18 of 57 and 17 of 56, p = 0.9) or lorazepam (38 of 57 and 35 of 56, p = 0.6) in the placebo and rivastigmine groups, respectively. CONCLUSION: This negative or, because of methodologic issues, possibly failed trial does not support short-term prophylactic administration of oral rivastigmine to prevent postoperative delirium in elderly patients undergoing elective cardiac surgery with cardiopulmonary bypass.

Zerbrochene Spiegel /1

Der Beitrag beschreibt eine doppelte, verfremdete und letztendlich tragische Spiegelung in der Wahrnehmung von Architektur zwischen Europa und Indien: zwischen 1780 und 1856 entstanden in der nordindischen Stadt Lucknow mehrere große Baukomplexe, die von den indisch-islamischen Herrschern der Stadt in europäisch-klassizistischen Formen gestaltet wurden. Nach dem indischen Aufstand, der in den Jahren 1857 und 1858 gegen die britische Herrschaft in Lucknow losbrach, wurden diese Bauten zum Gegenstand einer scharfen europäischen Architekturkritik. Der erste Abschnitt – "Das Eigene und das Fremde" – betrachtet die westliche Rezeption dieser europäisch-klassizistischen Bauten, die über Jahrzehnte durch ein Negativurteil bestimmt war, das sich aus der politischen Interpretation des indischen Aufstands erklärt. Der zweite Abschnitt – "Kopie und Synthese" – geht auf die Suche nach den Zusammenhängen für die positive Europarezeption in Lucknow und für die negative Kritik dieser Bauten in Europa. Es erweist sich, dass die Praxis von Architekturkopie und die Wahrnehmung europäischer Stilformen bei der Übernahme klassizistischer Motive in Indien deutlich anders war als das exakte und moralisch überhöhte Verständnis von Stilformen im Europa nach 1850.

Rationalities, Practices, and Resistance in Post-Welfarism. A Comment on Kevin Stenson

The former welfare arrangements are, according to Stenson, in a process of fundamental re-structuring. Or regarding the topic of this SW&S-Special Issue (was meint ihr genau mit dem vorhergehenden Satz? Man sollte einen Satz besser nicht mit ‘or’ anfangen): the spatial scales of the welfare states are under siege. With this advice Stenson assents to the prevalent description of a fundamental shift of former welfare arrangements since the last third of the 20th century (see for welfare policy research, research on human services and social work: Castel 2003; Clarke 2004; Gilbert 2004; Lessenich 2008/forthcoming; Marston/McDonald 2006; Webb 2006).

The Yanque prospect (Peru): from polymetallic Zn-Pb mineralization to a nonsulfide deposit

The Yanque nonsulfide Pb-Zn deposit (inferred resources 12.5 Mt @ 3.7% Pb and @ 3.5% Zn) is located in the Andahuaylas-Yauri ore province (Cuzco, southern Peru). The deposit occurs within a base metal mineralized district, centered on the medium-sized Dolores porphyry copper. A thorough geological, mineralogical and geochemical study has carried out in order to define: the relationships between the Dolores Cu-porphyry ore and the Yanque Zn-Pb polymetallic mineralization, and the characteristics of the economic nonsulfide concentrations. Both sedimentary and igneous rocks constitute the backbone of the Yanque-Dolores area. The sedimentary lithologies belong to the Soraya, Mara and Ferrobamba Fms. (upper Jurassic-middle Cretaceous). The Yanque orebody is hosted by the Mara Fm., which prevailingly consists of a siliciclastic sedimentary breccia. The original sulfide mineralization consisted of galena, pyrite and sphalerite. The host rock has been affected by a strong hydrothermal alteration, characterized by prevailing sericite/illite, as in the typical porphyry-related phyllic-argillic alteration stage, and by minor kaolinite, dolomite and quartz. Minor element geochemistry, characterized by Sb, As, Mn, Ag and locally also by Cu, points to magmatic-hydrothermal related mineralizing fluids. The Pb isotopic compositions from Dolores and Yanque sulfides are similar, and are typical of the Tertiary magmatically-derived ores in this part of Peru. The hydrothermally altered rocks at Yanque have the same Pb isotopic compositions as the sulfides, thus confirming the hypothesis that the Yanque primary Zn-Pb mineralization may have been produced by hydrothermal circulation related to the emplacement of the Dolores Cu-porphyry, as it is the case of other porphyry Cu systems associated with polymetallic mineralization elsewhere. However, no simple genetic model for the mineralization involving just one fluid circulation episode is able to explain the data. The Yanque economic nonsulfide ore association consists of sauconite, hemimorphite, smithsonite and cerussite, which result from the weathering and alteration of the original sulfide mineralization. Zinc is allocated mainly in sauconite (Zn-smectite), rather than in carbonates: a factor strictly related to the prevailing siliciclastic character of the host rock. Distinctive features of the Yanque orebody are the comparable ore grades for both Pb and Zn (3.5% Zn and 3.7% Pb), and the inverse supergene chemical zoning. In fact, contrary to other supergene ores of this type, zinc prevails in the top zone of the Yanque deposit, whereas lead content increases with depth. Considering the different mobility of the two metals in solution, it may be assumed that most of the primary zinc that was the source for the Yanque nonsulfides was originally located far from the position occupied by the galena mineralization, whose remnants have been observed on site. Zinc sulfides may have been originally contained in the eroded rock volumes that surrounded the actual deposit: the zinc-rich solutions have possibly migrated through the siliciclastic Mara Fm. and precipitated the nonsulfide minerals by porosity filling and replacement processes. In this sense, the Yanque secondary Zn-Pb deposit could be considered as a special type of “Exotic” mineralization.
