The most common nutritional problems in nursing home residents are weight loss and concomitant protein energy undernutrition. Although the causes of weight loss in these patients can usually be treated, they are rarely identified in the nursing home. Depression and adverse drug effects are the most common causes of weight loss. We discuss the appropriate use of feeding tubes in the nursing home and the early use of enteral feeding to prevent the development of severe protein energy undernutrition. Vitamin deficiencies, especially folate and pyridoxine deficiencies, frequently develop in nursing home residents. Hip fractures are often associated with vitamin D deficiency. Trace mineral deficiencies (for example, zinc deficiency) can aggravate immune deficiency and slow wound healing. Inadequate fluid intake leads to dehydration, hypotension, and, in persons with diabetes mellitus, hyperosmolarity. Finally, food intake itself can cause postprandial hypotension (which in turn may precipitate falls), produce electrolyte shifts, and result in aspiration pneumonia. Physical activity programs are an important component of nursing home care that may have an effect on nutritional status, and simple, cost-effective programs may be as beneficial as high-technology programs. Careful attention to the nutritional intake of nursing home residents is both a clinical and a quality-of-life issue.

Hip fractures on the paretic side are a serious post-stroke complication and may result from disuse hemiosteopenia, hypovitaminosis D, and an increasing risk of falls. To evaluate short-term immobilization effects, we assessed calcium metabolism in 89 patients 1 week after the hemiplegic stroke and in 36 controls. Patient activity was rated using the Barthel index (BI). Sera from stroke patients and control subjects were assayed for ionized calcium, parathyroid hormone (PTH), 25-hydroxyvitamin D (25-OHD), 1, 25-dihydroxyvitamin D (1,25-(OH)(2)D), bone Gla protein (BGP; a bone formation marker) and pyridinoline cross-linked carboxy-terminal telopeptide of type I collagen (ICTP; a bone resorption marker). Patients' serum concentrations of ionized calcium and ICTP were higher than in controls and correlated negatively with BI; their BGP concentrations were low, correlating positively with BI. Concentrations of serum 25-OHD, 1,25-(OH)(2)D, and PTH also were low; serum 25-OHD was at a deficient level (<10 ng/ml) in nine patients (10%), an insufficient level (10-20 ng/ml) in 56 (63%), and a sufficient level (>20 ng/ml) in only 24 (27%). PTH correlated negatively with calcium and 1,25-(OH)(2)D. Hypovitaminosis D is common in acute stroke patients. Immobilization from acute hemiplegia can increase bone resorption and serum calcium, and inhibit PTH secretion and 1,25-(OH)(2)D production to add to the effects of hypovitaminosis D.
