Items in AFP with MESH term: Nutritional Status
ABSTRACT: Determining the level of prealbumin, a hepatic protein, is a sensitive and cost-effective method of assessing the severity of illness resulting from malnutrition in patients who are critically ill or have a chronic disease. Prealbumin levels have been shown to correlate with patient outcomes and are an accurate predictor of patient recovery. In high-risk patients, prealbumin levels determined twice weekly during hospitalization can alert the physician to declining nutritional status, improve patient outcome, and shorten hospitalization in an increasingly cost-conscious economy.
ABSTRACT: Newborn infants may be transferred to a special care nursery because of conditions such as prematurity (gestation less than 37 weeks), prolonged resuscitation, respiratory distress, cyanosis, and jaundice, and for evaluation of neonatal sepsis. Newborn infants' core temperature should be kept above 36.4 degrees C (97.5 degrees F). Nutritional requirements are usually 100 to 120 kcal per kg per day to achieve an average weight gain of 150 to 200 g (5 to 7 oz) per week. Standard infant formulas containing 20 kcal per mL and maternal breast milk may be inadequate for premature infants, who require special formulas or fortifiers that provide a higher calorie content (up to 24 kcal per mL). Intravenous fluids should be given when infants are not being fed enterally, such as those with tachypnea greater than 60 breaths per minute. Hypoglycemia can be asymptomatic in large-for-gestational-age infants and infants of mothers who have diabetes. A hyperoxia test can be used to differentiate between pulmonary and cardiac causes of hypoxemia. The potential for neonatal sepsis increases with the presence of risk factors such as prolonged rupture of membranes and maternal colonization with group B streptococcus. Jaundice, especially on the first day of life, should be evaluated and treated. If the infant does not progressively improve in the special care nursery, transfer to a tertiary care unit may be necessary.
ABSTRACT: A pressure ulcer is a localized injury to the skin or underlying tissue, usually over a bony prominence, as a result of unrelieved pressure. Predisposing factors are classified as intrinsic (e.g., limited mobility, poor nutrition, comorbidities, aging skin) or extrinsic (e.g., pressure, friction, shear, moisture). Prevention includes identifying at-risk persons and implementing specific prevention measures, such as following a patient repositioning schedule; keeping the head of the bed at the lowest safe elevation to prevent shear; using pressure-reducing surfaces; and assessing nutrition and providing supplementation, if needed. When an ulcer occurs, documentation of each ulcer (i.e., size, location, eschar and granulation tissue, exudate, odor, sinus tracts, undermining, and infection) and appropriate staging (I through IV) are essential to the wound assessment. Treatment involves management of local and distant infections, removal of necrotic tissue, maintenance of a moist environment for wound healing, and possibly surgery. Debridement is indicated when necrotic tissue is present. Urgent sharp debridement should be performed if advancing cellulitis or sepsis occurs. Mechanical, enzymatic, and autolytic debridement methods are nonurgent treatments. Wound cleansing, preferably with normal saline and appropriate dressings, is a mainstay of treatment for clean ulcers and after debridement. Bacterial load can be managed with cleansing. Topical antibiotics should be considered if there is no improvement in healing after 14 days. Systemic antibiotics are used in patients with advancing cellulitis, osteomyelitis, or systemic infection.
