Patients with advanced dementia frequently develop eating difficulties and weight loss. Enteral feeding tubes are often used in this situation, yet benefits and risks of this therapy are unclear. We searched MEDLINE, 1966 through March 1999, to identify data about whether tube feeding in patients with advanced dementia can prevent aspiration pneumonia,(More)
The purpose of the current study was to evaluate the effectiveness of a multidisciplinary Hip Fracture Service in the treatment of hip fractures in elderly patients. Baseline information and hospital outcomes were compared for 510 patients over the age of 65 with hip fracture treated before and after the institution of the Hip Fracture Service. Data(More)
Aging is associated with reduced GH, IGF-I, and sex steroid axis activity and with increased abdominal fat. We employed a randomized, double-masked, placebo-controlled, noncross-over design to study the effects of 6 months of administration of GH alone (20 microg/kg BW), sex hormone alone (hormone replacement therapy in women, testosterone enanthate in(More)
OBJECTIVE To better understand and characterize clinical excellence in academia by exploring the perspectives of clinically excellent faculty in the top American departments of medicine. PARTICIPANTS AND METHODS Between March 1 and May 31, 2007, 2 investigators conducted in-depth semistructured interviews with 24 clinically excellent Department of(More)
UNLABELLED Postoperative delirium is a major problem in elderly patients undergoing surgical repair of hip fracture. It is imperative to identify potentially treatable preoperative factors associated with the onset of postoperative delirium to optimize outcome. We sought to determine what preoperative variables are associated with postoperative delirium in(More)
CONTEXT Hormone administration to elderly individuals can increase lean body mass (LBM) and decrease fat, but interactive effects of growth hormone (GH) and sex steroids and their influence on strength and endurance are unknown. OBJECTIVE To evaluate the effects of recombinant human GH and/or sex steroids on body composition, strength, endurance, and(More)
The records of 510 elderly patients with hip fractures admitted to our institution between January 1995 and December 2000 were retrospectively reviewed to determine the incidence and type of developed medical complications and their economic implications. Of those 510 patients, 217 (43%) developed at least 1 medical complication, most frequently electrolyte(More)
UNLABELLED It is unclear how brief postoperative delirium (DEL) affects functional outcomes. In this study, we sought to determine if patients with brief postoperative DEL (<6-wk duration) have different living situations when compared with non-DEL patients after hip fracture repair. In a prospective study, patients admitted to the geriatric hip fracture(More)
BACKGROUND Aging is associated with concomitant declines in activity of the growth hormone (GH) and gonadal steroid axes, and in bone mineral density (BMD), in both sexes. Long-term estrogen replacement slows bone loss and prevents fractures in postmenopausal women, whereas the effects of supplementation of GH or testosterone on bone metabolism and BMD in(More)
