Book Description
J. E. Fischer, M.D. Professor Greep, ladies and gentlemen. It is a great pleasure for me and the participants to be present at this International Meeting of Parenteral Nutri tion. This meeting would not have been possible five years ago. At that time we were still arguing about central vs. peripheral routes, efficacy of the tech nique, and still getting accustomed to our ability to support patients nutri tionally. Within the last five years these discussions, which seem almost futile in retrospect, have been put aside. Both techniques, we know how, work quite well and have their own indications. Having become comfortable with the technique, it is now time to enter the second phase of parenteral nutrition, and that is the differentiation of the technique for the benefit of different patients. Over the next two days we will be discussing several problems which at the present time are central to the entire subject of parenteral nutrition. Is a fat calorie the same as a carbo hydrate calorie? What is the effect on protein metabolism of the fat calorie as opposed to the carbohydrate calorie? Are they equivalent? Are'there situations in which one is superior to the other? Perhaps we will find out tomorrow in the panel.

Book Description
Nearly all medical specialities treat patients whose illnesses necessitate a means of nutrition which bypasses the gastrointestinal tract. Parenteral nutrition consequent ly means the administration of nutrient and building materials in qualitatively utilizable form and in quantitatively adequate amount by the intravenous route. This guarantees the requirements for energy and building materials under a variety of conditions, and compensates for any losses that might occur. The basis for any parenteral nutrition is the knowledge of the biochemical processes of intermediary metabolism under physiological and pathophysiological conditions (e. g. , starvation, post-stress metabolism, hypoxia, microcirculatory disturbances, etc. ). Only taken in these contexts can nutrient and bodybuilding sub stances be combined, measured out, and administered in such a way as to be definitively useful to the body. Research into the biochemistry and the patho biochemistry of intermediary metabolism has demonstrated possibilities, by means of which we may be able to "outwit" (to some extent) disturbances in utilization of certain nutrients under defined pathologic conditions. If the body receives and transforms substrate-precursors (e. g. , sorbitol), it can maintain an adequate level of nutrient and life-support substances; this slow rate of transformation to the substrate makes allowance for the limited utilization capacity, and covers the needs of the body by roundabout means. Some of the problems can now be considered solved, but a great many are still in the very early stages of elucidation, or await basic research.

Book Description
Parenteral nutrition has been one of the most significant therapeutic advances of the past twenty years. Many patients have survived very serious illness only because of intravenous nutrition for either short or very long periods of time. The indications for parenteral nutrition are simple and can be summarised as the inability to ingest necessary nutrients for a significant time during increased metabolic demands. Many problems in the preparation of energy sources and amino acid solutions have been solved so that the time is opportune to review what has been achieved and discuss recent advances and current thinking in the light of future requirements. The next phase in parenteral nutrition will undoubtedly be the provision of regimens designed for specific situations. The needs of the neonate for example are known to differ from adult requirements. The choice of carbohydrate for intravenous use has been a matter of much of glucose both in biochemical and clinical terms discussion. The supremacy now seems well established. The value of intravenous fat is well documented, but the interchange of fat and carbohydrate as calorie sources and the effects of prolonged infusions of fat merit further investigation. The evidence that isotonic amino acids are utilized effectively when given alone due to the availability of endogenous energy sources has led to a greater understanding of the metabolic changes and demands associated with injury and sepsis.

Book Description
Perinatal Medicine: Clinical and Biochemical Aspects of the Evaluation, Diagnosis and Management of the Fetus and Newborn is a collection of papers the details the advances in various areas of perinatal medicine. The materials in the title emphasizes on tackling the clinical and biomedical aspects of perinatal medicine. The coverage of the text includes the endocrine tests in the assessment of pregnancy; role of amniocentesis in elective cesarean section; and pharmacological prevention of premature delivery. The selection also covers the management of diabetes in pregnancy; nutritional management of low birth weight and premature infants; and the immunologic content of human breast milk. The book will be of great use to students, researchers, and practitioners of perinatal medicine. Other health professionals, such as nurses and midwives will also benefit from the text.

Book Description
Containing 45 papers written by outstanding international authors from 14 countries, this three-volume compendium brings together the elements needed to understand the factors which influence the utilization of amino acids. The wide-ranging topics include descriptions of metabolic pathways and mechanisms of the biological utilization of amino acids, as well as factors that influence amino acid bioavailability in enteral and parenteral nutrition. The use of amino acids to improve the quality and safety of the diet is presented. Also discussed are amino acid precursors of biogenic amines and the role of amino acids in atherosclerosis, cancer, and immunity. Scientists from many disciplines will benefit from this broad overview.

Book Description
It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.
