This book examines a range of contemporary ideas and arguments concerning the core yet unsettled clinical issues. Important aspects of pulmonary disorders are tackled such as occupational and environmental respiratory health hazards, the role of vitamin D supplementation in airway allergy, or nutritional aspects of care for lung cancer patients. Metabolic disorders affecting the processes of atherogenesis and systemic inflammation also are tackled. Attention is directed to rare but severe pediatric disease entities. Articles give readers practice at analyzing clinical data. The practical insights emphasize the role of science in transforming biomedical knowledge and care. This volume will be essential reading for clinicians, researchers, and other healthcare professionals engaged in effective patient care and therapy.
