Emergency presentations following youth suicide attempts during the COVID-19 pandemic: temporal trends and associations with containment measures

J. Schmier, Paul L. Plener, Diana Klinger

The COVID-19 pandemic has raised concerns about adverse effects on youth mental health, including suicidal behavior. While suicide mortality remained stable in many countries, less is known about temporal changes in suicide attempts presenting to clinical services. This study examined trends in …

Experimental Coronary Artery Bypass Operation

Jens‐Rainer Allenberg, R. D. Braun, Michael Dietze, Rainer Finke et autres

Myocardial blood flow and ventricular function was studied in seven dogs with chronic myocardial ischemia before and after coronary bypass grafting. Restoring blood flow in an area of 25% of the anterior wall of the left ventricle did not significantly improve overall …

Acute Changes in Adhesive Platelet Count and Pulmonary Hemodynamics in Tourniquet Shock of Dogs

K. van Ackern, U. B. Brückner, J. E. Deuster, H. Leinberger et autres

In 14 anesthetized and heparinized dogs, a tourniquet shock is induced by a 4 h lasting ligation of both hindlegs. Investigation of pulmonary artery pressure, cardiac output and platelet count reveals a narrowing of the pulmonary vascular bed. Immediately after release of …

[Pretreatment with heparin in experimental trauma and haemorrhagic shock].

T Klöss, H. Leinberger, Brückner Ub, Saggau Ww et autres

A severe shock is produced in 18 mongrel dogs by standardized bone trauma and haemorrhagic shock. Impairment of microcirculation is demonstrated by acidosis, reduced oxygen uptake and disseminated intravascular coagulation (DIC). Further, a specific increase in pulmonary vascular resistance--independent of the reduction …

Pulmonale Druck-Fluß-Relation nach pulmonaler Mikroembolie: Prophylaktische Therapie mit Heparin und Acetylsalizylsäure/Dipyridamol

H. Leinberger, U. Bleyl, U. B. Brückner, T Klöss et autres

Fibrinhaltige Mikrothromben und Thrombozytenaggregate werden für eine Steigerung des pulmonalen Strömungswiderstandes in verschiedenen Schockzuständen verantwortlich gemacht. Ihre Bedeutung für die pulmonale Hypertonie der Höhenkrankheit und der primären pulmonalen Hypertonie wird diskutiert.

[Effects of dextran, gelatine and homologous plasma on circulation in shock caused by severe anemia in the dog].

Wendel Dietze, P. Rentrop, Schmidt Hd, J. Schmier

Irreversible shock is produced in 28 anaesthetized mongrel dogs by withdrawal of erythrocytes and substitution by dextran, gelatine or plasma to an average Hb of 4.5g%. In contrast to other shock models cardiac output and perfusion pressure are not decreased by this …
