Comparative Study
The influence of a whole food vegan diet with Nori algae and wild mushrooms on selected blood parameters.
Vegan and vegetarian diets could overcome many diseases of civilization. This study examines whether a whole food vegan diet with Nori algae and wild mushrooms can provide a sufficient quantity of critical nutrients. ⋯ Vegans following a whole food diet had a borderline supply of vitamin B12. Folic acid, vitamin B6, TSH, iron metabolism, and the blood count were in the normal range. Vegans taking dietary supplements demonstrated satisfactory overall results. An ingestion of sundried mushrooms can contribute to the supply of vitamin D.

Intraosseous (IO) access is a valuable tool in prehospital locations and in emergency departments when other forms of vascular access are unavailable. Creatinine is often used for dose adjustment of drugs that may be administered through intraosseous cannulae. We aimed to study the possibility of analysing creatinine in intraosseous samples and study the accuracy and precision of such measurements. ⋯ Based on our findings intraosseous samples can be used for creatinine determination in emergency settings.

In patients undergoing cardiac surgery, perioperative coagulopathy and the use of allogenic blood products are independently associated with increased mortality and major perioperative cardiac and non-cardiac adverse events. Hemotherapy should be based on specific hemotherapy algorithms rather than "clinical judgments". However, whether hemotherapy should be based on "classical" conventional laboratory coagulation analyses or Point-of-Care (POC) measures is discussed controversially. ⋯ Unfortunately, the studied hemotherapy--algorithms are very complex and thus hard to integrate into daily practice. In close cooperation of three German University Hospitals, the authors developed and implemented two more comprehensive and practical hemotherapy algorithms that are based on either POC measures or conventional coagulation testing. Here we present and discuss the structure and limitations of these algorithms.

The transfusion efficacy of ATK, which contain fully functional platelets, is beyond all doubt. The equivalence of ATK and PTK has been subject of many studies. Some of those studies show the superiority of ATK's, while others do not, but there have been no studies that demonstrated a superiority of PTK's. ⋯ Through pathogen reduction, in parallel with platelet loss (Apoptosis), the function of the treated platelets is impaired. Alternatively, the cell destruction caused during this process could result in a release of platelet microRNA directly into the supernatant or in microvesicles. This reduction of microRNA will affect the storage of the platelets. (ABSTRACT TRUNCATED)

Observational Study
Aggregometric assessment of clonidine's impact on the efficacy of dual platelet inhibition.
Clonidine is commonly used as a calmative and antihypertensive agent in perioperative care. Due to the drug's alpha-2-agonistic effects, it has recently been hypothesised that clonidine may affect platelet aggregability. The present investigation aimed to study the potential impact of clonidine on the efficacy of dual antiplatelet therapy. ⋯ The results of this study indicate that clonidine does not affect platelet aggregability in patients treated with dual antiplatelet therapy. The findings of the study also indicate that ex vivo induced platelet aggregation in the ASPItest and ADPtest increases with the duration between blood drawing and MEA analyses.
