Laboratory Assessment of Vitamin Status provides a comprehensive understanding of the limitations of commonly used approaches used for the evaluation of vitamin status, reducing harm in the general health setting. It outlines the application of 'Best Practice' approaches to the evaluation of vitamin status, giving physicians and other healthcare professionals the opportunity to make evidence-based interventions. Nearly every metabolic and developmental pathway in the human body has a dependency on at least one micronutrient. Currently, the clinical utility of approaches taken by laboratories for the assessment of vitamin status is generally poorly understood, missing the opportunity to diagnosis vitamin deficiencies. This essential reference gives clinical and biomedical scientists an understanding of the limitations of commonly used approaches to the evaluation of vitamin status in the general health setting through change in practice. Nutritionists and dietitians gain an understanding of more sophisticated markers of vitamin status. - Describes specialist assays in sufficient detail to enable laboratories to replicate what is being performed by expert groups - Provides detailed information that supports laboratories in the setting up of methods for the evaluation of vitamin status - Informs laboratories looking for third party providers of specialist investigations - Provides an essential overview of reference ranges for each vitamin

As aging trends in the United States and Europe in particular are strongly suggestive of increasingly older society, it would be prudent for health care providers to better prepare for such changes. By including physiology, disease, nutrition, pharmacology, pathology, radiology and other relevant associated topics, Geriatric Gastroenterology fills the void in the literature for a volume devoted specifically to gastrointestinal illness in the elderly. This unique volume includes provision of training for current and future generations of physicians to deal with the health problems of older adults. It will also serve as a comprehensive guide to practicing physicians for ease of reference. Relevant to the geriatric age group, the volume covers epidemiology, physiology of aging, gastrointestinal physiology, pharmacology, radiology, pathology, motility disorders, luminal disorders, hepato-biliary disease, systemic manifestations, neoplastic disorders, gastrointestinal bleeding, cancer and medication related interactions and adverse events, all extremely common in older adults; these are often hard to evaluate and judge, especially considering the complex aging physiology. All have become important components of modern medicine. Special emphasis is be given to nutrition and related disorders. Capsule endoscopy and its utility in the geriatric population is also covered. Presented in simple, easy to read style, the volume includes numerous tables, figures and key points enabling ease of understanding. Chapters on imaging and pathology are profusely illustrated. All chapters are written by specialists and include up to date scientific information. Geriatric Gastroenterology is of great utility to residents in internal medicine, fellows in gastroenterology and geriatric medicine as well as gastroenterologists, geriatricians and practicing physicians including primary care physicians caring for older adults.

This review updates the report by the Committee on Medical Aspects of Food Policy (COMA) "Folic acid and the prevention of disease" (Report on health and social subjects no. 50, 2000, ISBN 0113223048). The Committee has weighed the evidence which shows significant benefits of folic acid fortification in reducing the risk of pregnancies affected by a neural tube defect (NTD) against the evidence of potential harm in fortification in relation to delaying diagnosis of vitamin B12 deficiency and increasing the progression of bowel cancer. It recommends mandatory fortification of flour with folic acid as the most effective way to increase folate intakes of women most at risk of NTD-affected pregnancies, provided voluntary fortification is controlled and advice is given about supplement use. Such a policy is judged to be of net benefit to the UK population as it would lead to a redistribution of folic acid intakes, improving the folate intake of low consumers while reducing the intakes of high consumers.

Explaining the practical implications of new discoveries in 'life-course biology', Nutrition and Lifestyle for Pregnancy and Breastfeeding is an informed resource on factors that affect offspring development. The impact of parental lifestyle and behavioural choices influence not only fetal development and birth outcomes, but also postnatal development, yet guidance on appropriate diet, behaviour, and exposures during pregnancy is often confusing and contradictory. With accessible explanations of the latest scientific research, and clear summaries and recommendations, this book is a valuable and authoritative guide for all levels of health care providers. The authors provide an overview of the background evidence, highlighting the importance of lifestyle choices prior to and during pregnancy. In-depth discussions of nutritional and lifestyle factors that impact on pregnancy and offspring outcomes are based on the latest research and exploration of key scientific studies. Nutrition and Lifestyle for Pregnancy and Breastfeeding is a manual offering both scientific and clinical evidence to empower health care providers and ensure they have the information necessary to confidently care for prospective and new parents.

Understand the rapidly growing complexities of obstetric hematology and high-risk pregnancy management, with experts in the field. Now in its second edition, this comprehensive and essential guide focuses on providing the best support for patients and clinical staff, to prevent serious complications in pregnancy and the post-partum period for both mother and baby. Wide-ranging and detailed, the guide offers discussions on basic principles of best care, through to tackling lesser-known hematological conditions, such as cytopenias and hemoglobinopathies. Updated with color illustrations, cutting-edge research, accurate blood film reproductions, and practical case studies, the revised edition places invaluable advice into everyday context. This unique resource is essential reading for trainees and practitioners in obstetrics, anesthesia, and hematology, as well as midwives, nurses, and laboratory staff. Clarifying difficult procedures for disease prevention, the guide ensures safety when the stakes are high. Reflecting current evidence-based guidelines, the updated volume is key to improving pregnancy outcomes worldwide.
