The predators were collected in mate crop in Cascavel and São Mateus do Sul, Paraná, Brazil and some other additional specimens in coffee and maize crops in Ribeirão Preto, São Paulo, Brazil. Illustrations obtained by SEM are given by the first time to the principal structures. Three species of Hemerobius were identified: H. bolivari Banks, 1910; H. domingensis Banks, 1941 and H. gaitoi Monserrat, 1996. H. domingensis is recorded for the first time to Brazil.

This research was carried out in order to compare the occurrence of insects in two maté cultivation systems, native and high tree density. It was performed from August/2000 to September/2001, in a private property in São Mateus do Sul county, in Paraná State, Brazil. Visual inspections of trees and light traps were used to evaluate insect populations in both areas. For Hedypathes betulinus (Klug) (Coleoptera, Cerambycidae), only six adults were observed in the dense area. Based on presence of sawdust at the basis of the trunk, it was obtained that the number of attacked trees did not surpass 11% in either area. For Gyropsylla spegazziniana (Lizer y Trelles) (Hemiptera, Psyllidae), the number of galls per tree was counted and it was observed that the population peak occurred from November to January. For Hylesia spp. (Lepidoptera, Saturniidae) and Thelosia camina Schaus (Lepidoptera, Eupterotidae), the presence of caterpillars on the trees was noticed from September to February, with the population peak in November and December. Adults of Hylesia spp. were more numerous in February and March. Two species that were not previously recorded for Brazil on maté were identified: Hylesia paulex Dognin (83%) and Hylesia remex Dyer (17%), collected with light traps. The maté caterpillar, T. camina was not collected with these traps. Nymphs and adults of Ceroplastes grandis Hempel (Hemiptera, Coccidae) were observed along the year on the branches, with population peak between April and June for the nymphs and from September to November for the adults. It should be considered that despite higher insect incidence in the dense area compared to the native area, the first presents higher yield, and that with a good pest management program the insect problems can be minimized.

BACKGROUND: Different studies have shown circadian variation of ischemic burden among patients with ST-Elevation Myocardial Infarction (STEMI), but with controversial results. The aim of this study was to analyze circadian variation of myocardial infarction size and in-hospital mortality in a large multicenter registry. METHODS: This retrospective, registry-based study was based on data from AMIS Plus, a large multicenter Swiss registry of patients who suffered myocardial infarction between 1999 and 2013. Peak creatine kinase (CK) was used as a proxy measure for myocardial infarction size. Associations between peak CK, in-hospital mortality, and the time of day at symptom onset were modelled using polynomial-harmonic regression methods. RESULTS: 6,223 STEMI patients were admitted to 82 acute-care hospitals in Switzerland and treated with primary angioplasty within six hours of symptom onset. Only the 24-hour harmonic was significantly associated with peak CK (p = 0.0001). The maximum average peak CK value (2,315 U/L) was for patients with symptom onset at 23:00, whereas the minimum average (2,017 U/L) was for onset at 11:00. The amplitude of variation was 298 U/L. In addition, no correlation was observed between ischemic time and circadian peak CK variation. Of the 6,223 patients, 223 (3.58%) died during index hospitalization. Remarkably, only the 24-hour harmonic was significantly associated with in-hospital mortality. The risk of death from STEMI was highest for patients with symptom onset at 00:00 and lowest for those with onset at 12:00. DISCUSSION: As a part of this first large study of STEMI patients treated with primary angioplasty in Swiss hospitals, investigations confirmed a circadian pattern to both peak CK and in-hospital mortality which were independent of total ischemic time. Accordingly, this study proposes that symptom onset time be incorporated as a prognosis factor in patients with myocardial infarction.

Background The principal causes of liver enzyme elevation among HIV-hepatitis B virus (HBV) co-infected patients are the hepatotoxic effects of antiretroviral therapy (ART), alcohol abuse, ART-induced immune reconstitution and the exacerbation of chronic HBV infection. Objectives To investigate the incidence and severity of liver enzyme elevation, liver failure and death following lamivudine (3TC) withdrawal in HIV-HBV co-infected patients. Methods Retrospective analysis of the Swiss HIV Cohort Study database to assess the clinical and biological consequences of the discontinuation of 3TC. Variables considered for analysis included liver enzyme, HIV virological and immunological parameters, and medication prescribed during a 6-month period following 3TC withdrawal. Results 3TC was discontinued in 255 patients on 363 occasions. On 147 occasions (109 patients), a follow-up visit within 6 months following 3TC withdrawal was recorded. Among these patients, liver enzyme elevation occurred on 42 occasions (29%), three of them (2%) with severity grade III and five of them (3.4%) with severity grade IV elevations (as defined by the AIDS Clinical Trials Group). Three patients presented with fulminant hepatitis. One death (0.7%) was recorded. Conclusions HBV reactivation leading to liver dysfunction may be an under-reported consequence of 3TC withdrawal in HIV-HBV co-infected patients. Regular monitoring of HBV markers is warranted if active therapy against HBV is discontinued.

Der am ehesten um 1200 entstandene ,Mauritius von Craûn' gilt als Forschungsproblem. Als gemeinsamen Nenner der kontroversen Zugänge zum Text konstatiert der Aufsatz das Bemühen um eine Verbindung der rätselhaften Erzählung mit einem durch die historische Distanz verlorenen oder verwischten Sinnzusammenhang über einen textexternen missing link. Demgegenüber wird ein themen- und handlungsanalytischer Zugriff vorgeschlagen: Thema der Erzählung ist die im 12. Jahrhundert vorrangig in der Lyrik entwickelte strukturelle Figur der Hohen Minne, die ihre Ästhetik aus einem Paradox gewinnt: Die Möglichkeitsbedingung dieser in beständigem Werben bestehenden Liebe, die niemals erfüllt werden darf, ist ihre Unmöglichkeit. Seine ideelle Füllung erhält das Modell durch eine darin vernetzte Ordnung höfischer Werte wie stæte, triuwe, milte oder mâze. Diese Werte, so die These, ,,erzählt" die Handlung des ,Mauritius': Hier wird nicht nur der Versuch unternommen, lyrische Struktur in narrative Struktur zu verwandeln, sondern auch der, eine ins lyrische Modell eingebettete Ordnung ethischen Wissens zu narrativieren. Einzelne Figurenhandlungen erscheinen aus dieser Perspektive weniger als Bestandteile eines inhaltlichen Entwurfs mit dem Anspruch übergreifender Stimmmigkeit und dem Fluchtpunkt eines Deutungsangebots, sondern als Ausdruck verschieden graduierter Negierungen oder Positivierungen eines bestimmtes Wertes. Hierfür sprechen auch die konstanten Über- oder Unterzeichnungen der Figurenhandlungen, die als markantestes Merkmal der narrativen Faktur des Textes beschrieben werden. Die Mikroanalyse einer einzelnen Szene zeigt ferner, wie die Dichotomie von Statik und Dynamik, die schon dem lyrischen Entwurf der Hohen Minne eingeschrieben ist und die durch die Narrativierung des lyrischen Konzepts im ,Mauritius' zunehmend virulent wird, in Sequenzen aufeinanderfolgender Doppelungen von Bewegung und Zustand auserzählt wird. Insgesamt lässt sich der ,Mauritius' als Erprobung von Verfahren verstehen, eine idealisierte höfische Welt in Analogie zum lyrischen Modus auch im narrativen Modus zu literarisieren: als ein Stück Erzählkasuistik.
