Ghrelin is a peptide hormone mainly produced by the stomach, which strongly stimulates the release of growth hormone (GH) via the GH secretagogue receptor 1a (GHSR-1a) located in the hypothalamus. It has been reported to exert performance-enhancing effects on myocardial function, and as both ghrelin and GHSR-1a are expressed in myocardial tissues, the(More)
Survivors of the acute respiratory distress syndrome (ARDS) often report traumatic memories from the intensive care unit (ICU) and display a high incidence of post-traumatic stress disorder (PTSD). As it is known that subjects with PTSD often show sustained reductions in circulating cortisol concentrations, we examined the relationship between serum(More)
The aim of this review is to summarize the historical background of drug resistance of Gram-positive pathogens as well as to describe in detail the novel lipopeptide antibiotic daptomycin. Pharmacological and pharmacokinetic aspects are reviewed and the current clinical use of daptomycin is presented. Daptomycin seems to be a reliable drug in the treatment(More)
BACKGROUND Endocannabinoids (ECs) are rapidly acting immune-modulatory lipid-signaling molecules that are important for adaptation to stressful and aversive situations.They are known to interact with glucocorticoids and other stress-responsive systems. Maladaptation to acute or chronic stress represents a major risk factor for the development of psychiatric(More)
BACKGROUND Mediastinitis is a severe complication after cardiac surgery. While improvement of prophylaxis and of medical and surgical therapy has reduced its incidence, the treatment of mediastinitis continues to be a challenging problem. Within this study, we report the successful use of daptomycin as supportive therapy in patients developing mediastinitis(More)
BACKGROUND Infection is a main cause of morbidity and mortality after heart surgery, with multi-resistant pathogens increasingly representing a challenge. Daptomycin provides bactericidal activity against gram-positive organisms that are resistant to standard treatment including vancomycin. METHODS A cohort of cardiac surgical patients, treated with(More)
We are presenting the case of a 76-year-old female scheduled for major abdominal surgery. Her past medical history was remarkable for a three-vessel coronary artery disease, with a severely impaired left ventricular function. She had already undergone complex coronary artery bypass surgery. Currently, she presented with the rare constellation of a(More)
BACKGROUND Kidney transplantation is the gold standard of therapy in patients with terminal renal insufficiency. Living donor transplantation is a well-established option in this field. Enlarging the donor's pool implicates the acceptance of an increased rate of comorbidities. Among them, coronary artery disease is a growing problem. An increasing number of(More)
Vasodilatory shock frequently occurs after cardiac surgery, particularly after cardiac assist device implantation. This complication is often associated with high mortality, especially if refractory to conventional vasoconstrictor treatment. Methylene blue, a guanylate cyclase inhibitor, has been successfully used in the management of vasodilatory shock(More)
