Publikováno v: EClinicalMedicine, Vol 64, Iss , Pp 102223- (2023)

Summary: Background: Poor functional capacity has been identified as an important modifiable risk factor for postoperative complications. Cardiopulmonary exercise testing (CPET) provides objective parameters of functional capacity (e.g., oxygen consu

Point-of-care detection and differentiation of anticoagulant therapy - development of thromboelastometry-guided decision-making support algorithms

Autor: Simon T. Schäfer, Anne-Christine Otto, Alice-Christin Acevedo, Klaus Görlinger, Steffen Massberg, Tobias Kammerer, Philipp Groene

Publikováno v: Thrombosis Journal, Vol 19, Iss 1, Pp 1-11 (2021)

Abstract Background DOAC detection is challenging in emergency situations. Here, we demonstrated recently, that modified thromboelastometric tests can reliably detect and differentiate dabigatran and rivaroxaban. However, whether all DOACs can be det

Viscoelastometry for detecting oral anticoagulants

Autor: Philipp Groene, Daniela Wagner, Tobias Kammerer, Lars Kellert, Andreas Giebl, Steffen Massberg, Simon Thomas Schäfer

Publikováno v: Thrombosis Journal, Vol 19, Iss 1, Pp 1-8 (2021)

Abstract Background Determination of anticoagulant therapy is of pronounced interest in emergency situations. However, routine tests do not provide sufficient insight. This study was performed to investigate the impact of anticoagulants on the result

Acute Exercise in Hypobaric Hypoxia Attenuates Endothelial Shedding in Subjects Unacclimatized to High Altitudes

Autor: Julia M. Kröpfl, Tobias Kammerer, Valentina Faihs, Hans-Jürgen Gruber, Jan Stutz, Markus Rehm, Ingeborg Stelzer, Simon T. Schäfer, Christina M. Spengler

Publikováno v: Frontiers in Physiology, Vol 10 (2020)

Travel of unacclimatized subjects to a high altitude has been growing in popularity. Changes in endothelial shedding [circulating endothelial cells (ECs)] and hematopoietic stem and progenitor cells (CPCs) during physical exercise in hypobaric hypoxi

Changes of hemodynamic and cerebral oxygenation after exercise in normobaric and hypobaric hypoxia: associations with acute mountain sickness

Autor: Tobias Kammerer, Valentina Faihs, Nikolai Hulde, Andreas Bayer, Max Hübner, Florian Brettner, Walter Karlen, Julia Maria Kröpfl, Markus Rehm, Christina Spengler, Simon Thomas Schäfer

Publikováno v: Annals of Occupational and Environmental Medicine, Vol 30, Iss 1, Pp 1-7 (2018)

Abstract Objective Normobaric (NH) and hypobaric hypoxia (HH) are associated with acute mountain sickness (AMS) and cognitive dysfunction. Only few variables, like heart-rate-variability, are correlated with AMS. However, prediction of AMS remains di

The impact of phosphate-balanced crystalloid infusion on acid-base homeostasis (PALANCE study): study protocol for a randomized controlled trial

Autor: Judith-Irina Pagel, Nikolai Hulde, Tobias Kammerer, Michaela Schwarz, Daniel Chappell, Alexander Burges, Klaus Hofmann-Kiefer, Markus Rehm

Publikováno v: Trials, Vol 18, Iss 1, Pp 1-10 (2017)

Abstract Background This study aims to investigate the effects of a modified, balanced crystalloid including phosphate in a perioperative setting in order to maintain a stable electrolyte and acid-base homeostasis in the patient. Methods/design This

Hypoxic-Inflammatory Responses under Acute Hypoxia: In Vitro Experiments and Prospective Observational Expedition Trial

Autor: Tobias Kammerer, Valentina Faihs, Nikolai Hulde, Manfred Stangl, Florian Brettner, Markus Rehm, Mareike Horstmann, Julia Kröpfl, Christina Spengler, Simone Kreth, Simon Schäfer

Publikováno v: International Journal of Molecular Sciences, Vol 21, Iss 3, p 1034 (2020)

Induction of hypoxia-inducible-factor-1α (HIF-1α) pathway and HIF-target genes allow adaptation to hypoxia and are associated with reduced incidence of acute mountain sickness (AMS). Little is known about HIF-pathways in conjunction with inflammati

Omission of tranexamic acid does not increase the amount of perioperative blood transfusions in patients undergoing one-level spinal fusion surgery: a retrospective propensity score-matched noninferiority study

Autor: Jonas Alfitian, Max Joseph Scheyerer, Axel Rohde, Volker Schick, Tobias Kammerer, Robert Schier

Publikováno v: Archives of Orthopaedic and Trauma Surgery. 143:2943-2950

Introduction Application of tranexamic acid (TXA) in spine surgery is very frequent even without signs of hyperfibrinolysis, although its beneficial blood-saving effects are offset by harmful adverse events such as thromboembolic incidents. Thus, we
