Synopsis The Importance Of Iron In Pathophysiologic Conditions by : Raffaella Gozzelino

The iron element (Fe) is strictly required for the survival of most forms of life, including bacteria, plants and humans. Fine-tuned regulatory mechanisms for Fe absorption, mobilization and recycling operate to maintain Fe homeostasis, the disruption of which leads to Fe overload or Fe depletion. Whereas the deleterious effect of Fe deficiency relies on reduced oxygen transport and diminished activity of Fe-dependent enzymes, the cytotoxicity induced by Fe overload is due to the ability of this metal to act as a pro-oxidant and catalyze the formation of highly reactive hydroxyl radicals via the Fenton chemistry. This results in unfettered oxidative stress generation that, by inducing protein, lipid and DNA oxidation, leads to Fe-mediated programmed cell death and organ dysfunction. Major and systemic Fe overloads occurring in hemochromatosis and Fe-loading anemias have been extensively studied. However, localized tissue Fe overload was recently associated to a variety of pathologies, such as infection, inflammation, cancer, cardiovascular and neurodegenerative disorders. In keeping with the existence of cross-regulatory interactions between Fe homeostasis and the pathophysiology of these diseases, further investigations on the mechanisms that provide cellular and systemic adaptation to tissue Fe overload are instrumental for future therapeutic approaches. Thus, we encourage our colleagues to submit original research papers, reviews, perspectives, methods and technology reports to contribute their findings to a current state of the art on a comprehensive overview of the importance of iron metabolism in pathophysiologic conditions.

Synopsis Iron Physiology and Pathophysiology in Humans by : Gregory J. Anderson

Iron Physiology and Pathophysiology in Humans provides health professionals in many areas of research and practice with the most up-to-date and well-referenced volume on the importance of iron as a nutrient and its role in health and disease. This important new volume is the benchmark in the complex area of interrelationships between the essentiality of iron, its functions throughout the body, including its critical role in erythropoiesis, the biochemistry and clinical relevance of iron-containing enzymes and other molecules involved in iron absorption, transport and metabolism, he importance of optimal iron status on immune function, and links between iron and the liver, heart, brain and other organs. Moreover, the interactions between genetic and environmental factors and the numerous co-morbidities seen with both iron deficiency and iron overload in at risk populations are clearly delineated so that students as well as practitioners can better understand the complexities of these interactions. Key features of the volume include an in-depth index and recommendations and practice guidelines are included in relevant chapters. The volume contains more than 100 detailed tables and informative figures and up-to-date references that provide the reader with excellent sources of information about the critical role of iron nutrition, optimal iron status and the adverse clinical consequences of altered iron homeostasis. Iron Physiology and Pathophysiology in Humans is an excellent new text as well as the most authoritative resource in the field.

Synopsis Nutrition and HIV by : Saurabh Mehta

The world continues to lose more than a million lives each year to the HIV epidemic, and nearly two million individuals were infected with HIV in 2017 alone. The new Sustainable Development Goals, adopted by countries of the United Nations in September 2015, include a commitment to end the AIDS epidemic by 2030. Considerable emphasis on prevention of new infections and treatment of those living with HIV will be needed to make this goal achievable. With nearly 37 million people now living with HIV, it is a communicable disease that behaves like a noncommunicable disease. Nutritional management is integral to comprehensive HIV care and treatment. Improved nutritional status and weight gain can increase recovery and strength of individuals living with HIV/AIDS, improve dietary diversity and caloric intake, and improve quality of life. This book highlights evidence-based research linking nutrition and HIV and identifies research gaps to inform the development of guidelines and policies for the United Nations’ Sustainable Development Goals. A comprehensive approach that includes nutritional interventions is likely to maximize the benefit of antiretroviral therapy in preventing HIV disease progression and other adverse outcomes in HIV-infected men and women. Modification of nutritional status has been shown to enhance the quality of life of those suffering HIV/AIDS, both physically in terms of improved body mass index and immunological markers, and psychologically, by improving symptoms of depression. While the primary focus for those infected should remain on antiretroviral treatment and increasing its availability and coverage, improvement of nutritional status plays a complementary role in the management of HIV infection.

Synopsis Hemochromatosis by : James C. Barton

Once thought rare, hemochromatosis is now acknowledged as one of the commonest inherited disorders, affecting one in two hundred people of western Caucasian descent. It is estimated to affect over one million people in the USA alone. This is the most comprehensive clinical reference yet on hemochromatosis. The international author team includes specialists in internal medicine, hematology, hepatology, genetics, biochemistry and molecular biology, and the contents cover all aspects of pathophysiology, epidemiology, diagnosis and treatment. The latest developments in the genetics of the disorder are well explained, and there are sections on screening, diagnostic techniques, and clinical complications. Social and ethical issues are also considered. Highly illustrated, up-to-date and authoritative, this is the definitive resource for all clinicians involved in the management of hemochromatosis, and will also be invaluable to scientists interested in iron metabolism and iron overload.

Synopsis Iron Metabolism by : Franz Gross

International Symposia sponsored by ClBA Basle have been held once a year since 1959 in various European countries. In con trast to the many scientific meetings organised by the ClBA FOUN DATION either at its headquarters in London or occasionally abroad, the subjects dealt with at these International Symposia have con cerned problems more directly related to ClBA'S own research work in the pharmaceutical field. The various topics covered up to the present reflect the far-reaching interests and the wide spread activities that a pharmaceutical enterprise develops in quite diverse fields of chemical, biological, and medical research, and to which the ba.sic approach is an increasingly important prerequisite for the development of a new and useful therapeutic agent. Iron metabolism came into the sphere of interest in connection with CIBA'S research on antibiotics and related natural products containing iron, substances which act in their metal-free form as strong and specific chelating agents. Of course, these observations, interesting though they are, would not in themselves have justi fied a symposium. It seemed, however, useful to examine the new results from a wider perspective and to attempt to relate them to present-day knowledge of iron metabolism in general its physiology, its pathology, and therapeutic aspects. The success of a scientific symposium depends on the concep tion of the programme and the selection of the participants.

Synopsis Anemia in the Elderly by : Lodovico Balducci

Anemia in the elderly has been properly defined as the silent epidemic, representing 3 million people in the United States aged 65 years and older. Incidence and prevalence of this condition increase with age. It differs in its etiology, pathogenesis and treatment from anemia in children and younger adults. Anemia is associated with reduced survival, increased risk of functional dependence and hospitalization, increased risk of congestive heart failure and stage renal disease and cognitive disorders. Approximately 70% of anemia in older individuals is reversible.

Synopsis Iron Chelation Therapy by : Chaim Hershko

Within the last few years, iron research has yielded exciting new insights into the understanding of normal iron homeostasis. Such development, and the evolution of improved strategies of Iron Chelating Therapy require better understanding of the pathophysiology of iron toxicity and the mechanism of action of iron chelating drugs. The timeliness of the present volume is underlined by several significant developments in recent years. New insights have been gained into the molecular basis of aberrant iron handling in hereditary disorders and the pathophysiology of iron overload. This volume highlights the impact of long term Iron Celating Therapy using deferoxamine or the new, but controversial oral iron chelator deferiprone based on experience gained by multicenter trails, with special emphasis on survival, morbidity and drug toxicity; it reviews the development of the new and improved orally effective chelators suitable for clinical use in the near future and examines novel strategies of iron chelating treatment for the control of cell proliferation in malignant disease or malaria.
