Nutritional Anemias

Anemias resulting from nutritional factors constitute the largest nutrition health problem affecting populations in both developed and developing nations. Nutritional Anemias examines these anemias in detail and offers a balanced approach that includes current research findings on the etiology and consequences of this important problem. Th

"This major new comprehensive guide focuses on particular topics in the field of nutritional anemias, with in-depth coverage on each relevant nutrient whose deficiency can cause anemia, their metabolism, dietary requirements and related information. This book presents the unique hematological, and non-hematological, manifestations of each deficiency, the varied settings and causes of deficiency, interactions with other problems, diagnostic approaches and tools, synthesizing the perspectives of epidemiology, public health, and clinical hematology. Covering approaches to medical management in individuals, as well as in susceptible populations such as children, pregnant women and the elderly; and preventive strategies, such as supplementation and fortification, this exceptional text will appeal to a wide audience, from the clinician learning about the epidemiology and public health aspects of food fortification, to the public health practitioner who needs to understand clinical approaches to key nutritional anemia issues"--Site web de l'éditeur

Understanding the causes of anemia is critical to inform appropriate strategies to prevent and treat anemia, particularly to reduce the risk of anemia and the burden of disease. The strength of this book lies in its cross-disciplinary nature. This publication summarizes the current state of evidence on the multifactorial causes of anemia, with a specific focus on nutritional anemia. The chapter authors are leading experts in nutrition and global health. The introductory chapters provide an overview of the global burden of anemia prevalence, the economic implications and functional consequences of anemia, and the significance of these factors to guide policy and programs. Subsequent chapters provide current evidence on iron and other micronutrient metabolism and homeostasis in regards to anemia, the multifactorial contributors to anemia (e.g. infection and genetics), and the interactions between nutrients that may contribute to anemia. The summarizing chapters detail program and policy approaches to treat, prevent and reduce anemia in the global context. Nutritional Anemia is a comprehensive resource for those involved in global health and nutrition policy, strategy, programming, or research, and serves as a guide for how government, NGO, and international agencies can effectively treat, prevent and reduce anemia globally.

This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

This book provides a comprehensive overview of benign hematologic disorders in children. Divided into nine sections, the text reviews common hematologic disorders or conditions that affect children, while providing state-of-the-art information on pathophysiology, diagnosis, treatment, and management strategies. The text begins with a section on hematopoiesis, and the next section covers red blood cell disorders. The following sections provide overviews of platelet disorders, white blood cell disorders, and coagulation disorders. The sixth and seventh sections discuss neonatal hematology and bone marrow failure syndrome. The eighth section reviews supportive care, while the final section covers miscellaneous subjects including pediatric vascular anomalies and complement dysregulation syndromes. Written by experts in the field, Benign Hematologic Disorders in Children: A Clinical Guide is a valuable resource for clinicians and practitioners who treat children afflicted with these disorders.

Each year thousands are told they suffer from anemia, but most have only a vague understanding of the condition. In fact, "anemia" is a generic term that includes myriad specific diseases, each of which has its own story regarding cause, manifestations, and treatments. Understanding Anemia gently builds upon elementary knowledge of biology to provide the general reader with a fairly sophisticated understanding of the various causes of anemia, of the methods used to make diagnoses, and of the principles of treatment. The book begins with a definition of anemia and a brief history of the scientific study of blood. It explains how the doctor makes the diagnosis and details the main types of anemia. Since the different conditions result from the failure of various organs, the reader will come away with a surprisingly broad understanding of human anatomy and physiology, encompassing the digestive, circulatory, and immune systems, nutrition, biochemistry, and heredity. Features: Specific anemias: iron deficiency, vitamin deficiencies, hemolytic anemias, hereditary anemias, and others Helpful appendices: a practical guide to the metric system, a brief review of general cell biology, a table of normal values in commonly ordered lab tests, a description of the bone marrow biopsy procedure, a list of pitfalls a doctor faces during the evaluation of the anemic patient, resources for further study (both in print and on the Internet)

Investigations of nutritional anemias of pregnancy made by WHO in India, Israel, Mexico, Poland and Venezuela have shown that the prevalence of anemia in pregnant women ranges from 21% to 80%. Iron deficiency was present in 40-99% of these women and has been responsible for the major occurrences of anemia. Studies on the absorption of iron from various foods indicated that it is necessary to express dietary iron intake in terms of both total iron intake and its absorbability. Loss of body iron occurs in the gastrointestinal tract, urine, sweat, by exfoliation of skin, and through blood loss attributed to parasitic infection. The optimum dietary requirements of iron when absorbed cover physiological losses and conditions such as growth and pregnancy. The total iron demanded during pregnancy is about 900 mg of which 200 mg is lost during and immediately following delivery. The iron requirement increases greatly during pregnancy and since the high requirment during the last trimester cannot be met from consumed food, the diet must be supplemented by administration of medicinal iron. The strengthening of education programs for mothers, sanitary measures particularly in rural areas, the supplementing of foods with iron by enriching wheat flour and baby foods, the supplementing of medicinal iron during pregnancy, the daily administration of small amounts of iron to schoolchildren and further studies on nutritional anemias are all means of changing the present nutritional status.
