Abstract

Parenteral nutrition (PN) must be initiated as soon as possible after delivery in very low birth weight (VLBW) preterm infants in order to prevent postnatal growth failure and improve neurodevelopmental outcome. When administered early, high levels of parenteral amino acids (AA) are well tolerated and prevent negative nitrogen balance. Although proteins are the driving force for growth, protein synthesis is energy demanding. Intravenous lipid emulsions (ILE) constitute a good energy source because of their high energy density and provide essential fatty acids (FA) along with their long-chain polyunsaturated fatty acid (LC-PUFA) derivatives necessary for central nervous system and retinal development. Early supply of ILE is not associated with increased morbidity. No significant differences were found between ILE based on soybean oil only and mixed ILE containing soybean oil in combination with other fat sources, except for a reduction in the incidence of sepsis with non-pure soybean ILE, and possibly less PN-associated liver disease with mixed ILE containing some fish oil. In preterm infants glucose homeostasis is still immature in the first days of life and abnormalities of glucose homeostasis are common. VLBW infants may not tolerate high levels of glucose infusion without hyperglycemia. Administering lower levels of glucose infusion as part of full early PN seems more successful than insulin at this stage. Postpartum there is a transition period when the water and electrolyte balance may be severely disturbed and should be closely monitored. Avoiding fluid overload is critical for preventing respiratory and other morbidities

Pressure sores are a well-recognized problem, with an etiology that is multifactorial and not solely a consequence of pressure itself. Malnutrition is one of the factors involved, namely low calorie and protein intake. Mainly elderly patients, patients after hip fracture, but also patients after trauma, burns or extended surgery require additional nutritional support to reduce the possibility of pressure ulcers developing. Evidence has shown the efficacy of percutaneous endoscopic gastrostomy in elderly patients with malnutrition and dementia. Nutritional support should include sufficient calories, protein, fat, carbohydrates, vitamins and minerals. Arginine is the main amino acid required and is essential for collagen deposition and wound healing. Vitamin A and zinc should be added to nutritional support.

Background: A beneficial effect was observed in patients with psoriasis vulgaris following balneotherapy with Dead Sea bath salt.

Objectives: To evaluate the possible role of trace elements in the effectiveness of balneotherapy. 

Methods: Serum levels of 11 trace elements were analyzed in 23 patients with psoriasis vulgaris who participated in a double-blind controlled study of balneotherapy, with either Dead Sea bath salt (12 patients) or common salt (11 patients). Thirteen healthy volunteers served as controls.

Results: The mean pre-treatment serum levels of boron, cadmium, lithium and rubidium were significantly lower in patients compared to controls, whereas the mean pre-treatment serum level of manganese was significantly higher in patients compared to controls. Balneotherapy with Dead Sea bath salt resulted in a significant decrease (P = 0.0051) in the mean serum level of manganese from 0.10 ± 0.05 mmol/L to 0.05 ± 0.02 mmol/L. The mean reduction in the serum level of manganese differed significantly (P = 0.002) between responders (% Psoriasis Area and Severity Index score reduction ³ 25) and non-responders (% PASI score reduction < 25). Following balneotherapy with Dead Sea bath salt the mean serum level of lithium decreased in responders by 0.01 ± 0.02 mmol/L whereas its level in non-responders increased by 0.03 ± 0.03 mmol/L. (P = 0.015).
Conclusions: Manganese and lithium may play a role in the effectiveness of balneotherapy with Dead Sea bath salt for psoriasis.
