RESUMEN

INTRODUCTION: Spine trauma is a common pathology that frequently requires neurosurgical intervention. Few studies have examined short-segment, 360-degree stabilization of traumatic thoracolumbar fractures. METHODS: A retrospective review was completed of adult and pediatric patients who underwent surgical correction for thoracolumbar fractures between December 2011 and December 2021. RESULTS: Forty patients met the inclusion criteria. The majority of patients presented with an American Spinal Injury Association (ASIA) score of D (n = 11) or E (n = 21). The most common level of injury was L1 (n = 20). The average length of stay was 11.7 days. Postoperatively, two patients had pulmonary emboli or deep venous thrombosis, and two had surgical site infections. Most patients were discharged to home (n = 21) or acute rehab (n = 14). The fusion rate at six months was 97.5%. Neurologically, all patients regained ambulation by >18 months follow-up. For the ASIA scale, most had a score of D (n = 4) or E (n = 32) at six months. The same trend was observed with the Frankel score, where most patients had either D (n = 5) or E (n = 31), improving to only two having a score of D at >18 months. CONCLUSIONS: Corpectomy followed by posterior fusion has a number of biomechanical benefits. This construct permits circumferential decompression, larger surface area for fusion, improved reconstitution of vertebral body height, reduced kyphosis, and an overall shorter segment. This results in fewer levels needing to be fused while enabling the greatest changes of successful fusion.

RESUMEN

BACKGROUND: Several modifiable lifestyle factors have been shown to have potential beneficial effects in slowing cognitive decline. Two such factors that may affect cognitive performance and slow the progression of memory loss into dementia in older adults are cognitive training and physical activity. There are currently no effective treatments for dementia; therefore, preventative strategies to delay or prevent the onset of dementia are of critical importance. OBJECTIVE: The aim of this study was to determine the relative effectiveness of simultaneous performance of memory training and aerobic exercise to a sequential performance intervention on memory functioning in older adults. METHODS: 55 older adults (aged 60- 75) with subjective memory impairments (non-demented and non-MCI) completed the intervention that consisted of 90-minute small group classes held twice weekly. Participants were randomized to either 4-weeks of supervised strategy-based memory training done simultaneously while stationary cycling (SIM) or sequentially after the stationary cycling (SEQ). Standardized neurocognitive measures of memory, executive functioning, speed of processing, attention, and cognitive flexibility were assessed at baseline and post-intervention. RESULTS: The SIM group, but not the SEQ group, had a significant improvement on composite memory following the intervention (t(51) = 2.7, p = 0.01, effect size (ES) = 0.42) and transfer to non-trained reasoning abilities (t(51) = 6.0, ES = 0.49) and complex attention (t(51) = 3.1, p = 0.003, ES = 0.70). Conversely, the SEQ group, but not the SIM, showed significant improvement in executive functioning (t(51) = 5.0, p = 0.0001, ES = 0.96). CONCLUSION: These findings indicate that a 4-week simultaneous memory training and aerobic exercise program is sufficient to improve memory, attention, and reasoning abilities in older adults.

RESUMEN

OBJECTIVE: The aim of this study was to determine whether functional status, as measured by the AcuteFIM instrument, can be used to predict discharge destination of stroke patients from the acute hospital setting. DESIGN: A retrospective cohort study was carried out in an urban academic medical center. Data were collected on 481 new-onset stroke patients 18 yrs or older in an acute hospital between January 1 and September 30, 2013. Functional Independence Measure (FIM) instrument data were linked to a subset of 54 patients who received additional services at an inpatient rehabilitation facility. A receiver operator characteristic curve was constructed to validate the predictive ability of the AcuteFIM instrument and to determine the optimal cutoff score associated with discharge to a community setting. RESULTS: All AcuteFIM items in stroke patients at admission demonstrated strong interitem correlation coefficients (all above 0.6) and high internal consistency (Cronbach α = 0.94). The AcuteFIM total score was positively associated with discharge to the community from the acute hospital (odds ratio, 1.06; 95% confidence interval, 1.05-1.07). Receiver operator characteristic curve analysis generated a c statistic of 0.89 (95% confidence interval, 0.87-0.92), indicating that the AcuteFIM instrument is predictive of patient discharge to the community setting. CONCLUSION: This study suggests that the AcuteFIM instrument is a reliable tool that can be used to predict discharge destination from the acute hospital among stroke patients.
