Disaster medicine faces complex challenges and will play an increasing role in the future. Disaster medicine is dominated by a phased imbalance of available and required resources. Various factors, such as a possible hazard for the rescue forces, inaccessible terrain or even destroyed infrastructure increase the complexity enormously. For casualties, this can mean a concentration of medical care on life-threatening conditions. The primary goal of emergency planning is to ensure standard or contingency care and to avoid crisis care.Hospitals and the preclinical emergency organizations must prepare for possible major emergencies or disasters. Easy-to-understand and just as easy to apply emergency plans are an important prerequisite for successful emergency management. These plans can only be guiding structures; the adaptation to the actual circumstances of the incident and the situation-adapted interpretation of the plans is the responsibility of the operational commanders. A clear leadership structure is essential for both preclinical and clinical operations. In this article, we describe important basic principles of disaster medicine mission planning and management.  Mortality in sepsis remains high. Various techniques for extracorporeal cytokine removal have been investigated as additional therapeutic measures in sepsis and septic shock.  To summarize a selection of extracorporeal blood purification techniques, with a special focus on therapeutic plasma exchange, and their current evidence in clinical use.  Non-systematic literature review.  Various extracorporeal blood purification techniques with different levels of evidence regarding cytokine removal, vasopressor sparing effects and reduction of mortality are currently in clinical use. Most extensively studied modalities include high-volume hemofiltration/dialysis with and without high cut-off filters a well as hemoadsorption techniques (including CytoSorb, and polymyxin-B filters). Despite partly encouraging observations regarding removal of inflammatory cytokines and hemodynamic stabilization, results from randomized studies did not show an effect on survival. Due to use of donor plasma as substitution fluid, therapeutic plasma exchange represents the only modality able to additionally replace protective and consumed factors.  The use of extracorporeal blood purification methods cannot be recommended for sepsis patients outside of clinical trials given the current lack of evidence of their efficacy. Future investigations should aim to homogenize the studied patient collective in respect to clinical sepsis severity, time point of intervention and different inflammatory (sub-)phenotypes.  The use of extracorporeal blood purification methods cannot be recommended for sepsis patients outside of clinical trials given the current lack of evidence of their efficacy.

Causes of AKI include patient specific factors (susceptibility e.g. age, pre-existing chronic kidney disease, chronic heart failure, diabetes) and patient unspecific factors (exposure e.g. sepsis, hypovolemia, cardiac surgery, nephrotoxin application). Mortality of severe AKI is in the range of 40 - 50%.AKI is accompanied by volume overload, electrolyte disorders, acidosis, and uremia. The diagnosis of AKI is based on an increase of creatinine levels and/or a decrease in urine output within 7 days after an insult. These 2 markers are late und unspecific, especially with regard to early identification of patients at risk of AKI. New AKI markers have been investigated within the last decade including NGAL (neutrophil gelatinase-associated lipocalin), the product of IGFBP-7 (insulin like growth factor binding protein 7) and TIMP-2 (tissue inhibitor of metalloproteinase 2), KIM-1 (kidney injury molecule 1) and the cysteine-protease-inhibitor cystatin C. New markers or a panel of new markers might improve the diagnosis of patients at risk of AKI in the future.There are currently no specific therapeutics in the treatment of AKI. Therefore, the prevention of AKI is of an utmost importance. The recommended preventive measures include optimization of hemodynamics and volume status, close monitoring of creatinine levels and urine output, avoidance or discontinuation of nephrotoxic drugs, normoglycemia and the application of alternatives to radiocontrast agents if possible.As the long term prognosis of AKI highly depends on renal recovery, the 2 major goals for the future will be 1) the early identification of patients at AKI risk and 2) the support of renal recovery of AKI patients.Concussion is the most common match injury in rugby union. Some players wear padded headgear, but whether this protects against concussion is unclear. https://www.selleckchem.com/products/talabostat.html In professional male rugby union players, we examined (i) the association between the use of headgear and match concussion injury incidence, and (ii) whether wearing headgear influenced time to return to play following concussion. Using a nested case-control within a cohort study, four seasons (2013-2017) of injury data from 1117 players at the highest level of rugby union in England were included. Cases were physician-diagnosed concussion injuries. Controls were other contact injuries (excluding all head injuries). We determined headgear use by viewing video footage. Sixteen percent of cases and controls wore headgear. Headgear use had no significant effect on concussion injury incidence (adjusted odds ratio=1.05, 95% CI 0.71-1.56). Median number of days absent for concussion whilst wearing headgear was 8 days, compared with 7 days without headgear. Having sustained a concussion in the current or previous season increased the odds of concussion more than four-fold (odds ratio=4.55, 95% CI 3.77-5.49). Wearing headgear was not associated with lower odds of concussions or a reduced number of days' absence following a concussion.
