Book Description
Introduction. Les anticoagulants sont l'une des classes médicamenteuses les plus fréquemment responsable d'accidents iatrogènes comme les saignements. Malheureusement, très peu de données sont disponibles concernant les caractéristiques et la gestion des patients admis en réanimation pour un saignement grave sous anticoagulant. Méthodologie. Une étude observationnelle rétrospective a été menée dans 4 services de réanimation de CHU français. De janvier 2007 à décembre 2018, tous les patients âgés de plus de 18 ans, admis en réanimation pour saignement extra-cérébral lié à l'anticoagulation, ont été inclus. Résultats. Au total, 393 patients ont été inclus dans les 4 unités françaises de réanimation. L'âge moyen était de 73 ± 13 ans, 38 % étaient des femmes et la plupart des patients présentaient des comorbidités (hypertension artérielle 70 %, cardiopathies 58 %, diabète 36 %). Les anticoagulants responsables du saignement étaient les anti-vitamines K (AVK : 53 %), les héparines (25 %) et les anticoagulants oraux directs (AOD : 7 %). L'incidence des saignements sous anticoagulants a augmenté au cours de la période 2007-2018, passant de 3.7/1000 admissions en 2007 à 5.5/1000 admissions en 2018, avec une stabilité de la responsabilité des AVK et une augmentation des saignements sous AOD. La mortalité en réanimation était d'environ 30%. En analyse multivariée, les facteurs associés à la mortalité étaient : Glasgow 12, TCA1.2, hyperlactatémie et support ventilatoire. La gestion médicale des hémorragies liées à l'anticoagulation et notamment l'antagonisation était peu conforme aux recommandations françaises et internationales, avec l'utilisation des concentrés de vitamine K et de complexe prothrombique perfusés uniquement chez 60 % des patients traités par AVK, et l'utilisation des concentrés de complexe prothrombique chez 25 % des patients traités par AOD. Conclusion. Les hémorragies extra-cérébrales sous anticoagulant admises en réanimation sont des complications graves responsables de défaillances d'organes et d'une mortalité importante. Leur incidence est en augmentation. La formation des cliniciens pour la prise en charge thérapeutique de ces accidents doit être améliorée.

Book Description
12 The average human body has in the order of 10 circulating platelets. They are crucial for hemostasis, and yet excessive platelet activation is a major cause of m- bidity and mortality in western societies. It is therefore not surprising that platelets have become one of the most extensively investigated biological cell types. We are, however, far from understanding precisely how platelets become activated under physiological and pathophysiological conditions. In addition, there are large gaps in our knowledge of platelet production from their giant precursor cell, the megakar- cyte. Understanding megakaryocyte biology will be crucial for the development of platelet gene targeting. The aim of Platelets and Megakaryocytes is therefore to bring together established and recently developed techniques to provide a comprehensive guide to the study of both the platelet and the megakaryocyte. It consists of five s- tions split between two volumes. The more functional assays appear in Volume 1, whereas Volume 2 includes signaling techniques, postgenomic methods, and a n- ber of key perspectives chapters. Part I of Volume 1, Platelets and Megakaryocytes: Functional Assays, describes many well established approaches to the study of platelet function, including aggregometry, secretion, arachidonic acid metabolism, procoagulant responses, pla- let adhesion under static or flow conditions, flow cytometry, and production of microparticles. Although one would ideally wish to perform experiments with human platelets, studies within the circulation using intravital microscopy require the use of animal models, which are described in Chapter 16, vol. 1.

Book Description
This book describes in detail the clinical presentation, diagnosis, and management of a wide range of congenital bleeding disorders. It will assist readers in overcoming the significant challenges involved in clinical and laboratory diagnosis and in providing effective clinical care that makes optimal use of new products, including recombinant factor concentrate. The coverage ranges from hemophilia A and B and von Willebrand disease to rare bleeding disorders such as congenital factor V, factor X, factor XI, and factor XIII deficiency and inherited platelet function disorders. The exceptional attention to rarer conditions is of particular importance given the considerable risk of overlooking them during diagnosis, with potential consequences for disease-related morbidity and mortality. The authors are acknowledged specialists in the field from across the world who have particular expertise in the disorder that they discuss. The book will be of value to hematologists, oncologists, pediatricians, laboratory specialists and technicians, general physicians, and trainees.

Book Description
Color Atlas of Equine Pathology offers a practical guide to identifying equine diseases, presenting a single resource with more than 1000 images showing predominantly gross pathology. Organized by body systems, the book allows for picture matching during or after an equine necropsy. In this user-friendly atlas, each chapter takes a common format, presenting the disease process as well as congenital, degenerative, inflammatory, and neoplastic sequences, with text boxes offering quick reference to key information. The book begins with an introductory chapter summarizing the principles of the equine field necropsy, and subsequent organ-based chapters depict gross features of disease, focusing on macroscopic digital images supplemented by histology and immunohistochemistry when necessary. Some clinical information for correlation with pathology is included. Color Atlas of Equine Pathology is an essential resource for diagnostic veterinary pathologists and pathology residents, as well as for equine practitioners performing necropsies in the field.

Book Description
Statins are widely prescribed to lower blood cholesterol levels and claim to offer unparalleled protection against heart disease. Believed to be completely safe and capable of preventing a whole series of other conditions, they are the most profitable drug in the history of medicine. In this groundbreaking book, GP Malcolm Kendrick exposes the truth behind the hype. He will change the way we think about cholesterol forever. Rubbishing the diet-heart hypothesis, in which clinical trials 'prove' that high cholesterol causes heart disease and a high-fat diet leads to heart disease, Kendrick lambastes a powerful pharmaceutical industry and unquestioning medical profession, who, he claims, perpetuate the madcap concepts of 'good' and 'bad' cholesterol and cholesterol levels to convince millions of people to unnecessarily spend billions of pounds on statins. Clearly and comprehensively debunking assumptions on what constitute a healthy lifestyle and diet, "The Great Cholesterol Con" is the accessible, indispensable and absorbing case against statins and for a more common-sense approach to heart disease and general wellbeing. No more over-hyped miracle drugs; no more garlic, red wine, anti-oxidants, fruit or vegetables; even a vegetarian diet is rejected in this controversial yet authoritative critique of how we have been mislead over how food and drugs affect our coronary health. Here, for the first time, is the invaluable guide for anyone who though there was a miracle cure for heart disease, "The Great Cholesterol Con" is a fascinating breakthrough that will set dynamite under the whole area.

Book Description
"The Yosephs have written the most stunning expose. In plain language they reveal the science, the corruption and the enormous conspiracy it took to bring statins to market. As fast paced as a Mickey Spillane novel they report the research, the fraud and the facts like a detective in hot pursuit of a Nazi war criminal. It is riveting. They have accomplished the impossible: they have made both complex science and medical history fascinating to read. What could not be done in an expose they accomplished with almost unbelievablable ease. It will change your paradigms about medicine forever."--p.[4] of cover.

Book Description
Endogenous neuoprotection is a phenomenon where a brief episode of ischemia renders the brain resistant against a subsequent longer-asting ischemia event. Experimentally, the author was able to model hypoxic preconditioning in animal model. Increasing knowledge of this endogenous neuroprotectin by ischemic tolerance may help to minimize neuronal damage following ischemic stroke and hypoxic encephalopathy. This book is, therefore, the first overview of this important topic and will certainly influence further investigations in clinical and neuroscience research.
