Introduction: Little is known about discrepancies between patients who present with or without STEMI following out-of-hospital cardiac arrest (OHCA). Material and Methods: All patients with OHCA who were admitted to our hospital between January 1st 2008 and December 31st 2013 were classified according to their initial laboratory and electrocardiographic findings into STEMI, NSTEMI or no ACS. Results: Overall, 147 patients [32 STEMI (21.8%), 28 NSTEMI (19.0%) and 87 no ACS (59.2%)] were included with a mean age of 63.7 ± 13.3 years;there were 84 men (57.1%) and 63 (42.9%) women. Of these, 63 patients (51.7%) received coronary angiography [29 STEMI (90.6%), 9 NSTEMI (32.1%) and 38 no ACS (43.7%)] showing a high prevalence of coronary artery disease (CAD) [28 STEMI (96.6%), 9 NSTEMI (100.0%) and 26 no ACS (68.4%)] requiring percutaneous coronary intervention (PCI) in 52 cases [28 STEMI (96.6%), 8 NSTEMI (88.9%) and 16 no ACS (42.1%)]. Discussion: Coronary angiography immediately after hospital admission is feasible if all are prepared for potential further resuscitation efforts during cardiac catheterization. Primary focus on haemodynamic stabilisation may reduce the rates of coronary angiographies in patients following OHCA. Altogether, our data support the call for immediate coronary angiography in all patients following OHCA irrespective of their initial laboratory or electrocardiographic findings.

Revealing the control of migratory fueling： An integrated approach combining laboratory and field studies in northern wheatears Oenanthe oenanthe

Migratory birds rely on fueling prior to migratory flights. Fueling in migrants is controlled by intrinsic as well as ex- trinsic factors. From captive studies we have started understanding the internal mechanisms controlling bird migration. Field studies have demonstrated the effects of external factors, such as food availability, weather, competitors, parasites or diseases, on the stopover behavior of migrants. However, an integrated approach is still missing to study coherently how the innate migration program interacts with the varying environmental cues and to estimate the contribution of the innate migration program and the environment to realized migration. The northern wheatear Oenanthe oenanthe offers a unique opportunity for integrated studies. It breeds across almost the whole Holarctic with just a ＂gap＂ between eastern Canada and Alaska. All breeding populations over- winter in sub-Saharan Africa which makes the northern wheatear one of the most long-distant migratory songbirds with extraor- dinary long non-stop flights across oceans. It is a nocturnal migrant which travels without parental or social aid/guidance. Thus, young birds rely entirely on endogenous mechanisms of timing, route selection and fueling on their first outbound migration. By establishing indoor housing under controlled conditions the endogenous control mechanisms of northern wheatear migration could be revealed. At the same time, environmental factors controlling fueling could be investigated in the field. On migration wheatears occur in a variety of habitats with sparse vegetation where their stopover behavior could be quantitatively studied in the light of ＂optimal migration＂ theory by the use of remote balances, radio-tagging and even experimentally manipulated food availability. The present paper summarizes our approach to understand the control of migration in northern wheatears by combin- ing field and laboratory studies at various spatial and temporal scales, and linking vario

Factors determining stopover decisions in migrating passerines on a small island

＜正＞ During migration between breeding and wintering areas, many passerines stop over on the small offshore island Helgoland （North Sea） in spring and autumn. There, about 50 km offshore, a bird of passage has no opportunity to search for any suitable surrounding habitat, and has to decide whether local conditions for resting/refuelling are adequate or to depart and continue migration forthwith. Several factors possibly influencing this decision were investigated in a five-year study of several species, the main target of which was the Northern Wheatear
