Other Uses. Other uses of hGH, eg, for bums, wound healing, cachexia, osteoporosis, aging, malnutrition, and obesity, are being investigated. These uses are ia various stages of development and trials are being carried out by several different pharmaceutical companies. 

Pantothenic acid is found in extracts from nearly all plants, bacteria, and animals, and the name derives from the Greek pantos, meaning everywhere. It is required in the diet of all vertebrates, but some microorganisms produce it in the rumens of animals such as cattle and sheep. This vitamin is widely distributed in foods common to the human diet, and deficiencies are only observed in cases of severe malnutrition. The eminent German-born biochemist Fritz Lipmann was the first to show that a coenzyme was required to facilitate biological acetylation reactions. (The A in... 

Organoselenium compounds in particular, once ingested, are slowly released over prolonged periods and result in foul-smelling breath and perspiration. The element is also highly toxic towards grazing sheep, cattle and other animals, and, at concentrations above about 5 ppm, causes severe disorders. Despite this, Se was found (in 1957) to play an essential dietary role in animals and also in humans — it is required in the formation of the enzyme glutathione peroxidase which is involved in fat metabolism. It has also been found that the Incidence of kwashiorkor (severe protein malnutrition) in children is associated with inadequate uptake of Se, and it may well be involved in protection... 

In arterioles, the hydrostatic pressure is about 37 mm Hg, with an interstitial (tissue) pressure of 1 mm Hg opposing it. The osmotic pressure (oncotic pressure) exerted by the plasma proteins is approximately 25 mm Hg. Thus, a net outward force of about 11 mm Hg drives fluid out into the interstitial spaces. In venules, the hydrostatic pressure is about 17 mm Hg, with the oncotic and interstitial pressures as described above thus, a net force of about 9 mm Hg attracts water back into the circulation. The above pressures are often referred to as the Starling forces. If the concentration of plasma proteins is markedly diminished (eg, due to severe protein malnutrition), fluid is not attracted back into the intravascular compartment and accumulates in the extravascular tissue spaces, a condition known as edema. Edema has many causes protein deficiency is one of them. 

Hepatobiliary disease occurs due to bile duct obstruction from abnormal bile composition and flow. Hepatomegaly, splenomegaly, and cholecystitis may be present. Hepatic steatosis may also be present due to effects of malnutrition. The progression from cholestasis (impaired bile flow) to portal fibrosis and to focal and multilobar cirrhosis, esophageal varices, and portal hypertension takes several years. Many patients are compensated and asymptomatic but maybe susceptible to acute decompensation in the event of extrinsic hepatic insult from viruses, medications, or other factors.7...

Hyperemesis gravidarum A rare disorder of severe and persistent nausea and vomiting during pregnancy that can result in dehydration, malnutrition, weight loss, and hospitalization. 

Essential fatty acid deficiency is rare but can occur with prolonged lipid-free parenteral nutrition, very low fat enteral formulas, severe fat malabsorption, or severe malnutrition. The body can synthesize all fatty acids except for linoleic and linolenic acid, which should constitute approximately 2% to 4% of total calorie intake. 

Eating disorders PN should be considered for patients with anorexia neivosa and severe malnutrition who are unable or unwilling to ingest adequate nutrition. 

Some dmgs are bound to plasma proteins in blood. Plasma protein levels in blood may be decreased in the elderly, but this is most often not clinically relevant since a drug s elimination increases when the free, unbound drug concentration is enhanced (Turnheim 1998). The plasma albumin level may however be markedly decreased in elderly suffering from malnutrition or severe disease. For those patients the concentration of the free unbound drug can reach toxic levels (Waiter-Sack and Klotz 1996). 

Malnutrition can also cause secondary osteoporosis in persons with different deficiencies of substances such as calcium and vitamin D. Malnutrition due to starvation caused by most severe or terminal chronic diseases and malabsorption due to inflammatory bowel diseases (colitis, Mb Crohn) can give rise to rapidly diminishing bone tissue. 

Delirium often has a multifactorial cause (Box 6.1). Elderly patients with severe illness or who are already cognitively impaired are vulnerable to delirium. Malnutrition or dehydration may further enhance the risk. The most common causes for delirium are drugs and diseases. Frail elderly who are vulnerable to delirium may be pushed into delirium by one dose of an inappropriate drug or by e.g. urinary retention whereas younger individuals are far more resistant. 

Several circumstances developed during the field test that necessitated repeating the ANOVA after certain data were omitted. For a series of samples, more than one child used the same sample number. This problem is understandable in a setting with a high incidence of protein-calorie malnutrition (19). There were also a few children in the study who were above tRe originally set upper age limit of five years. ANOVAs were made excluding both...

The amonnt of protein synthesised and then released in (iv) and (v) is abont 70 g each day. Even under conditions of starvation or malnutrition, proliferation and differentiation of stem cells located in the crypts of the villi are important to provide the cells necessary for replenishment of those lost from the villi. New cells move up the villus to replace those lost at the top. Under these conditions, amino acids are not available from the intestine and have to be taken up from the blood across the basolateral membrane. A low level of amino acids in the blood, due to chronic malnutrition, will prevent or reduce the rate of proliferation of these cells, so that digestion of even the small amount of food ingested during malnutrition, or refeeding after starvation, is difficult. A vicious circle thus results from protein-deficient diets which increase the risk of development of protein-energy-malnutrition. This is especially severe in children but may also contribute to the clinical problems that occur in the elderly whose diets are of low quality.
