Nontraumatic vs. traumatic spinal cord injury: a rehabilitation outcome comparison.

OBJECTIVE: Nontraumatic spinal cord injury (SCI) represents a significant proportion of individuals admitted for SCI rehabilitation; however, there is limited literature regarding their outcomes. As our society continues to age and nontraumatic injuries present with greater frequency, further studies in this area will become increasingly relevant. The objective of this study was to compare outcomes of patients with nontraumatic SCI with those with traumatic SCI after inpatient rehabilitation. DESIGN: A longitudinal study with matched block design was used comparing 86 patients with nontraumatic SCI admitted to a SCI rehabilitation unit and 86 patients with traumatic SCI admitted to regional model SCI centers, controlling for age, neurologic level of injury, and American Spinal Injury Association impairment classification. Main outcome measures included acute and rehabilitation hospital length of stay, FIM scores, FIM change, FIM efficiency, rehabilitation charges, and discharge-to-home rates. RESULTS: Results indicate that when compared with traumatic SCI, patients with nontraumatic SCI had a significantly (P < 0.01) shorter rehabilitation length of stay (22.38 vs. 41.35 days) and lower discharge FIM scores (57.3 vs. 65.6), FIM change (18.6 vs. 31.0), and rehabilitation charges ($25,050 vs. $64,570). No statistical differences were found in acute care length of stay, admission FIM scores, FIM efficiency, and community discharge rates. CONCLUSIONS: The findings indicate that patients with nontraumatic SCI can achieve rates of functional gains and community discharge comparable with traumatic SCI. Whereas patients with traumatic SCI achieved greater overall functional improvement, patients with nontraumatic SCI had shorter rehabilitation length of stay and lower rehabilitation charges. These findings have important implications for the interdisciplinary rehabilitation process in the overall management and outcome of individuals with nontraumatic SCI.

Neoplastic vs. traumatic spinal cord injury: an inpatient rehabilitation comparison.

OBJECTIVE: To compare demographics, injury characteristics, and functional outcomes of patients with neoplastic spinal cord compression with those with traumatic spinal cord injuries. DESIGN: A prospective 5-yr comparison was undertaken comparing 34 patients with neoplastic spinal cord compression with 159 patients with traumatic spinal cord injury. RESULTS: Patients with neoplastic spinal cord compression were significantly older, more often female, and unemployed than patients with traumatic spinal cord injury. Neoplastic spinal cord compression presented more often with paraplegia involving the thoracic spine, and injuries were more often incomplete compared with traumatic spinal cord injury. Patients with neoplastic spinal cord compression had a significantly shorter rehabilitation length of stay compared with those with traumatic spinal cord injury. The neoplastic group had significantly lower FIM change scores. Both groups had similar FIM efficiencies and discharge to home rates. CONCLUSIONS: Patients with neoplastic spinal cord compression have different demographic and injury characteristics but can achieve comparable rates of functional gains as their traumatic spinal cord injury counterparts. Although patients with traumatic injuries achieve greater functional improvement, patients with neoplasms have a shorter rehabilitation length of stay and comparable FIM efficiencies and home discharge rates.

Predictors for return to work after spinal cord injury: a 3-year multicenter analysis.

OBJECTIVE: To examine the ability of the Motor Index Score (MIS), in combination with demographic variables, to predict return to work during a 3-year period for individuals with spinal cord injury (SCI). METHODS: Prospectively collected data, between 1986 and 1995, submitted to the National Spinal Cord Injury Statistical Center were analyzed to determine the prediction of return to work utilizing variables of education, ethnicity, age, marital status, gender, and MIS. Individuals, aged 18 to 65 yrs, employed at the time of their injury, were evaluated at discharge from rehabilitation and at 1 (YR1), 2 (YR2), and 3 (YR3) years postinjury (sample sizes of 1,857, 1,486, and 1,177, respectively). RESULTS: The most important predictors of return to work were education, MIS, ethnicity, and age at onset of SCI. These variables resulted in a high rate of accuracy for predicting across all 3 yrs (YR1, 81%; YR2, 82%; YR3, 77%). CONCLUSIONS: The ability to predict return to work after SCI was shown utilizing MIS and demographic variables, with nearly 80% accuracy. This suggests that return to work after SCI is a dynamic process, with the level of importance of each variable changing with time postinjury.

A double-blind, placebo-controlled study of sucrose polyester in hypercholesterolemic outpatients.

Sucrose polyester (SPE) was studied in a double-blind, placebo-controlled trial in 91 outpatients with primary hypercholesterolemia. All patients maintained an isocaloric diet with cholesterol intake of 400 mg/day and a polyunsaturated to saturated fat ratio of 0.8 to 1.2 for the duration of the study. The study sequence consisted of a diet lead-in period, a first 8-wk treatment period, a 4-wk washout period, and a second 8-wk treatment period. Subjects were randomly assigned to six groups that differed by SPE dose (8, 16, and 32 g/day) and by the treatment period in which either SPE or an olive oil placebo was given in a bread spread formulation. Compared to placebo, the 8, 16, and 32 g/day doses of SPE decreased low-density lipoprotein cholesterol by 2%, 4% (p less than 0.05), and 5% (p less than 0.05) respectively, without changing high-density lipoprotein cholesterol. On SPE, 14/91 (15%) of the subjects experienced a decrease in low-density lipoprotein cholesterol greater than or equal to 10%, while only 2/91 (2%) showed this decrease with placebo.

Sucrose polyester: substitution for dietary fats in hypocaloric diets in the treatment of familial hypercholesterolemia.

In five obese women heterozygous for familial hypercholesterolemia, we assessed the combination of weight loss and sucrose polyester (SPE) in lowering low-density lipoprotein cholesterol (LDLC). After a 10-day basal hypocaloric (1426 cal/day), 270 mg cholesterol, P/S 1.2:1 diet, an average of 36 g of dietary fat/day was replaced by 36 g of an 80/20 SPE-hydrogenated palm oil mixture, providing 30 g SPE for 30 days; during the SPE substitution period mean dietary cholesterol and P/S were unchanged, mean caloric intake was 1104 cal/day. During the hypocaloric basal diet, mean weight fell 1.2 kg, p less than 0.02, total plasma cholesterol fell 8% from 358 +/- 46 to 330 +/- 47 mg/dl, p less than 0.01, LDLC fell 4% from 264 +/- 37 to 254 +/- 44 mg/dl, p greater than 0.1, and mean high-density lipoprotein cholesterol fell 11%, from 52 +/- 4 to 46 +/- 4, p less than 0.05. Over the 30-day SPE substitution, mean cholesterol fell 20% from 330 +/- 47 at the end of the basal diet to 265 +/- 42 mg/dl, p less than 0.001; mean LDLC fell 23%, from 254 +/- 44 to 195 +/- 41 mg/dl (p less than 0.01); weight fell 4%, p less than 0.01, from 91 +/- 7 to 87 +/- 7 kg, and mean high-density lipoprotein cholesterol fell 11% from 46 +/- 4 to 41 +/- 2, p less than 0.05. Hypocaloric removal of dietary fat by SPE, an artificial fat with culinary properties of conventional dietary fats, effectively reduces LDLC (by 23%) in familial hypercholesterolemia subjects, with additive effects of SPE and weight loss.
