Book Description
This volume is a reference handbook focusing on diseases like Marfan syndrome, Ehlers-Danlos syndrome, Loeys-Dietz syndrome and other heritable soft connective tissue diseases. The book presents detailed information for both basic scientists and for clinicians seeing patients. It is also a stepping stone for new investigations and studies that goes beyond the facts about the composition and biochemistry of the connective tissue and extracellular matrix, as the authors connect individual components to specific aspects of various soft tissue disorders and to the actual or potential treatment of them. Progress in Heritable Soft Connective Tissue Diseases features very prominent physicians and scientists as contributors who bring their most recent discoveries to the benefit of readers. Their expertise will help clinicians with proper diagnosis of sometimes elusive and uncommon heritable diseases of soft connective tissues. This book also offers an update on the pathophysiology of these diseases, including an emphasis on unifying aspects such as connections between embryonic development of the different types of connective tissues and systems, and the role of TGF-beta in development and physiology of soft tissues. This new set of data explains, at least in part, why many of these disorders are interconnected, though the primary pathophysiological events, such as gene mutations, may be different for each disorder.

Ehlers-Danlos Syndrome: A Multidisciplinary Approach
Author: J.W.G. Jacobs
Publisher: IOS Press
ISBN: 1614998787
Category : Medical
Languages : en
Pages : 370
Book Description
Generalized hypermobility has been known since ancient times, and a clinical description of Ehlers-Danlos syndrome (EDS) is said to have first been recorded by Hippocrates in 400 BC. Hypermobility syndromes occur frequently, but the wide spectrum of possible symptoms, coupled with a relative lack of awareness and recognition, are the reason that they are frequently not recognized, or remain undiagnosed. This book is an international, multidisciplinary guide to hypermobility syndromes, and EDS in particular. It aims to create better awareness of hypermobility syndromes among health professionals, including medical specialists, and to be a guide to the management of such syndromes for patients and practitioners. It is intended for use in daily clinical practice rather than as a reference book for research or the latest developments, and has been written to be understandable for any healthcare worker or educated patient without compromise to the scientific content. The book is organized as follows: chapters on classifications and genetics are followed by chapters on individual types, organ (system) manifestations and complications, and finally ethics and therapeutic strategies, with an appendix on surgery and the precautions which should attend it. A special effort has been made to take account of the perspective of the patient; two of the editors have EDS. The book will be of interest to patients with hypermobility syndromes and their families, as well as to all those healthcare practitioners who may encounter such syndromes in the course of their work.

Learning from Disease in Pets
Author: Rebecca A. Krimins
Publisher: CRC Press
ISBN: 0429508492
Category : Medical
Languages : en
Pages : 294
Book Description
Learning from Disease in Pets: A ‘One Health’ Model for Discovery is the first encompassing reference guide for veterinarians, researchers and physicians on conducting studies using spontaneous models of disease in animals. The study of naturally occurring disease in (pet) animals can help model our understanding of the biology, prevention and therapy of human and animal diseases. Studies of pet dogs, for instance, can aid treatment of complex medical problems such as cancer, orthopedic, cardiopulmonary, and neuro-inflammatory diseases, and zoonotic infections. Each chapter within this novel cross-species approach is contributed by a leader, or leaders, in their field of research. Using clinical trials to learn how pets with real diseases respond to therapy can lead to breakthroughs in human medicine, as well as benefiting pets suffering from otherwise debilitating illness. Despite similarities of diseases across species, there are very few spontaneous models of disease used in research compared with models where disease is induced in healthy laboratory animals. Many medical researchers and veterinarians have a multitude of questions regarding how to use naturally occurring diseases in pets for the discovery of treatments and diagnostics: this book will demonstrate how to safely make this happen. This book encourages veterinarians to build on and disseminate existing findings for the wider benefit of pets and humans. Many pets suffering from incurable illnesses may benefit from clinical trials; the book includes a section on the imperative communication styles necessary within the research environment and with clients, a compelling discussion on the ethics of using pets in veterinary clinical research, comprehensive tables of diseases that spontaneously occur in animals and humans, the regulatory requirements necessary to move therapy from benchside research to patient bedside, as well as intricate details on how to design a robust clinical study.

Sex differences in atherosclerosis and exercise effects
Author: Liam Ward
Publisher: Linköping University Electronic Press
ISBN: 9176850978
Category :
Languages : en
Pages : 81
Book Description
Cardiovascular disease (CVD) is the leading cause of death globally, with atherosclerosis being the main cause of cardiovascular diseases. Atherosclerosis is an inflammatory disease of the blood vessel wall, which over time will cause thickening and hardening of the vessel wall. Atherosclerosis can result in catastrophic vascular events, such as myocardial infarction and stroke. There are distinct sex differences in CVD mortality at different ages, before menopause women have a lower mortality of CVD in comparison to men, which equalises after menopause. In addition to sex differences in the incidence of CVD, there are also distinct sex differences in the phenotype of atherosclerotic plaques, with men generally developing more severe and vulnerable plaques that are at risk of rupture. This thesis aimed to investigate the sex differences in atherosclerosis, in particular how the proteome and pathophysiology differs. In addition, we sought to investigate the potential benefit of an exercise programme, in reducing CVD risks, using a randomised controlled trial including postmenopausal women. Sex differences in atherosclerosis were first investigated via proteomic analysis of human carotid endarterectomy samples. Initially, five intraplaque biopsies were taken from distinct atheroma regions, including; internal control, fatty streak, plaque shoulder, plaque centre, and fibrous cap. Protein extracts from these biopsies were subjected to analysis by mass spectrometry. The novel sampling method was successful in reducing the effect of plaque heterogeneity, a limitation in previous proteomic studies of atherosclerosis, and a number of previously unreported proteins were identified in human carotid atheroma. In addition to this, with the inclusion of multivariate statistical modelling, it was found that 43 proteins significantly discriminated the carotid atheroma between men and women. These proteins were grouped by function, and it was found that atheroma from men was associated with the increased abundance of inflammatory response proteins, including phospholipase-A2 membrane associated and lysozyme C, and atheroma from women was associated with increased abundance of blood coagulation, complement activation, and transport proteins, notably including; antithrombin-III, coagulation factor XII, and afamin. In addition, differences were also ii observed in the abundance of iron metabolism related proteins. These sex differences were further expanded upon from a pathophysiological perspective. Immunohistochemistry stainings of ferritin and transferrin receptor 1 were found significantly increased in the atheroma from men. Moreover, the levels of plasma haemoglobin were also significantly increased in men and were associated with the development of more vulnerable and severe plaque types. The more vulnerable and severe plaque types were also associated with significantly greater macrophage infiltration. In summary, these results are indicative of men developing atheroma with greater inflammation that are more vulnerable, due to increased iron and inflammatory proteins and macrophage infiltration, whereas atheroma from women develop with less inflammation and a more stable phenotype. The randomised controlled clinical trial aimed at investigating the effects of resistance training (RT), over a 15-week period, in postmenopausal women. Plasma samples were obtained at week-0 and week-15 of the study period, and analyses were performed primarily using a series of immunoassays. Results showed that women participating in RT, with good compliance, were associated with significant decreases in plasma levels of ferritin, lipids, and inflammatory adipokines. These results suggest that the use of regular RT may be a beneficial intervention in reducing the levels of body iron, lipids, and inflammation, all of which are risk factors for the development of CVD. However, validation studies are required in a larger cohort of postmenopausal women, in addition to the inclusion or complementary studies in middle-aged men. In summary, the works included in this thesis further expand on the current knowledge of sex differences in atherosclerosis, and also provides information on the potential of an exercise intervention to beneficially reduces the effects of known risk factors of CVD.
