Brain Health Loss Mediates the Effect of Infarct Volume on Functional Outcome in Ischemic Stroke.

IMPORTANCE: Brain health may facilitate resilience to detrimental consequences from neurological diseases. Infarct volume is associated with poor functional outcome after acute ischemic stroke (AIS), but potential mediating effects through stroke-related brain health loss have not been investigated. OBJECTIVE: To determine whether stroke-related brain health loss, quantified by change in MRI derived effective Reserve (eR), mediates the effect of acute infarct volume on functional outcome after AIS. DESIGN: Observational multicenter cohort study. SETTING: We analyzed data from the GASROS (n=488) and MRI-GENIE (n=560) cohorts, collected 2003-2011. PARTICIPANTS: Adult patients consecutively diagnosed with AIS, with available admission MRI. EXPOSURE: At admission, white matter hyperintensity (WMH) and normal-appearing brain volumes were assessed on T2-FLAIR, and acute infarct volume on diffusion weighted imaging. WMH was normalized by brain volume, creating WMH load. We quantified brain health using eR, a latent variable incorporating age, WMH load, and normal-appearing brain volume. ΔeR reflected the change in eR when acute infarct volume was included, representing stroke-related brain health decline. Mediation analysis was used to determine if ΔeR mediates the effect of infarct volume on functional outcome (modified Rankin Scale [mRS] at 90 days). MAIN OUTCOME MEASURE: Proportion of mediating effect. RESULTS: We included 1,048 patients (median age 67y, 38% females). At baseline, median NIHSS score was 3 (IQR 1-7), median infarct volume 3.1mL (IQR 0.9-15.5). At 90 days, median mRS score was 1 (IQR 1-3) and 51 (5%) patients had died. In mediation analysis, ΔeR significantly mediated 36% (95% CI 16-56%) of the total effect of infarct volume on functional outcome (direct effect (ß=0.15 [95% CI 0.09-0.22], p<0.001; indirect effect mediated through ΔeR: ß=0.09 [95% CI 0.04 to 0.14], p=0.001). In subgroup-analyses, the mediative effect was apparent among female but not male, and among patients aged >67y but not ≤67y. CONCLUSIONS AND RELEVANCE: Stroke-related structural brain health loss mediates about one third of the effect of acute infarct volume on functional outcome after ischemic stroke, with important sex and age differences. Brain health significantly influences outcome and recovery potential, and may be considered a key biomarker when modeling outcome after AIS.

Comparison of the APACHE III, APACHE II and Glasgow Coma Scale in acute head injury for prediction of mortality and functional outcome.

OBJECTIVES: This study examines the efficacy of the predicting power for hospital mortality and functional outcome of three different scoring systems for head injury in a neurosurgical intensive care unit (NICU). DESIGN: On the day of admission, data were collected from each patient to compute the Acute Physiology, Age, and Chronic Health Evaluation (APACHE) II and III, and Glasgow Coma Scale (GCS) scores. Hospital mortality was defined as the deaths of patients before discharge from hospital. Early mortality was defined as death before the 14th day after admission. Late mortality was defined as death after the 15th day from admission. Functional outcome was evaluated by Index of Independence in Activities of Daily Living (Index of ADL). SETTING: An 8-bed NICU in a 1270-bed medical center in Taichung Veterans General Hospital. PATIENTS AND PARTICIPANTS: Two hundred non-selected patients with acute head injury were included in our study in a consecutive period of 2 years. Patients less than 14 years old were not included. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: Sensitivity, specificity and correct prediction outcome were measured by the chi-square method in three scoring systems. The Youden index was also obtained. The best cut-off point in each scoring system was determined by the Youden index. The difference in Youden index was calculated by Z score. A difference was also considered if the probability value was less than 0.05. The area under Receiver Operating Characteristic (ROC) curve was computed. Then the area under ROC of each scoring system was compared by Z score. There was statistical significance if p was less than 0.05. For prediction of hospital mortality, the best cut-off points are 55 for APACHE III, 17 for APACHE II and 5 for GCS. The correct prediction outcome is 82.4% in APACHE III, 78.4% in APACHE II and 81.9% in the GCS. The Youden index has best cut-off points at 0.68 for APACHE III 0.59 for APACHE II, and 0.56 for GCS. The area under Receiver Operating Characteristic (ROC) curve is 0.90 in the APACHE III, 0.84 in the APACHE II and 0.86 in the GVS. There are no statistical differences among APACHE III and II, and GCS in terms of correct prediction outcome, Youden Index and the area under the ROC curve. Other physiological variables excluding GCS in APACHE III and II (AP III-GCS, AP II-GCS) have less statistical value in the determination of mortality for acute head injury. For the prediction of late mortality, APACHE III and II yield significantly better results in the area under the ROC curve, correct prediction and Youden index than those of GCS. Other physiological variables (AP III-GCS and AP II-GCS) play an important role in the prediction of late mortality in APACHE scores. For prediction of the functional outcome of surviving patients with acute head injury, the APACHE III yields the best results of correct prediction outcome, Youden index and the area under the ROC curve. CONCLUSION: The APACHE III and II may not replace the role of GCS in cases of acute head injury for hospital or early mortality assessment. But for prediction of the late mortality, the APACHE III and II have better accuracy than GCS. Other physiological variables excluding GCS in the APACHE system play a crucial contribution for late mortality. GCS is simple, less time-consuming and economical for patients with acute head injury for the prediction of hospital and early mortality. The APACHE III provides better prediction for severe morbidity than GCS and APACHE II. Therefore, the APACHE III provides a good assessment not only for hospital and late mortality, but also for functional outcome.

Symptomatic and functional outcome of bipolar disorder in Butajira, Ethiopia.

BACKGROUND: Limited information is available on the outcome of bipolar disorder in developing countries. OBJECTIVE: To describe the symptomatic and functional outcome of bipolar disorder. METHODS: The psychoses and affective disorder modules of the CIDI were used to screen 68,378 individuals by a door-to-door survey of a defined district in Ethiopia. In addition, key informants were used to identify individuals with probable major mental illnesses. SCAN interviews were completed at the second stage to confirm the diagnosis. A total of 315 cases of bipolar disorder were identified, of which 264 (69 recent-onset and 195 prevalent cases) were prospectively followed for a mean of 2.5 (range 1-4) years by baseline and annual clinical assessments using symptom rating scales. Functional dimensions of the SF-36 scale were used to describe functional outcome. Random coefficient analyses were used to evaluate potential correlates of outcome. RESULTS: The magnitudes of mania and depression symptoms were elevated at baseline but improved with follow-up, although the improvement was less marked for depression. Sociodemographic or clinical variables were not associated with the improvements in symptomatic outcome. Between 35% and 47% of the recent-onset cases had functional role restrictions, while 42-52% of long-standing cases had such restrictions during the follow-up years. Similarly, social and physical functioning deficits were also present in 52-86% and 35-47% of recent-onset and long-standing cases, respectively. The magnitude of depression and mania symptoms was associated with poor functional outcome, while male sex, rural residence and being married were associated with better functional outcome. CONCLUSION: Although there were improvements in function with follow-up, between one-third and one-half of cases continued to have functional deficits.

Discharge destination and motor function outcome in severe stroke as measured by the functional independence measure/function-related group classification system.

OBJECTIVES: Function-related groups based on the Functional Independence Measure have been proposed as a model for a prospective payment system for medical rehabilitation. This study describes discharge destination and motor function outcomes in a sample of patients with stroke from the FIM-FRG STR1 classification. STUDY DESIGN: A retrospective review of 293 cases of stroke from the years 1993 to 1995. The demographic and outcome characteristics of this sample were described. RESULTS/CONCLUSIONS: Forty-five percent of the patients were discharged to home after a mean length of stay of 23.8 days in acute medical rehabilitation. Patients who were discharged home had higher admission and discharge motor FIM scores than those discharged to a subacute facility or long-term care facility, although the correlation between motor FIM score and discharge destination was low to moderate. Median discharge motor FIM scores indicate considerable residual disability in this classification after rehabilitation. Research problems that address methods to improve the usefulness of the FIM-FRG system in a prospective payment system are discussed.

Functional outcomes after ileal pouch-anal anastomosis for chronic ulcerative colitis.

OBJECTIVE: To assess long-term outcomes after ileal pouch-anal anastomosis (IPAA) for chronic ulcerative colitis (CUC) with specific emphasis on patient sex, childbirth, and age. SUMMARY BACKGROUND DATA: Childbirth and the process of aging affect pelvic floor and anal sphincter function independently. Early function after IPAA is good for most patients. Nonetheless, there are concerns about the impact of the aging process as well as pregnancy on long-term functional outcomes after IPAA. METHODS: Functional outcomes using a standardized questionnaire were prospectively assessed for each patient on an annual basis. RESULTS: Of the 1,454 patients who underwent IPAA for CUC between 1981 and 1994, 1,386 were part of this study. Median age was 32 years. Median length of follow-up was 8 years. Pelvic sepsis was the primary cause of pouch failure irrespective of sex or age. Functional outcomes were comparable between men and women. Eighty-five women who became pregnant after IPAA had pouch function, which was comparable with women who did not have a child. Daytime and nocturnal incontinence affected older patients more frequently than younger ones. Incontinence became more common the longer the follow-up in older patients, but this was not found in younger patients. Poor anal function led to pouch excision in only 3 of 204 older patients. CONCLUSIONS: Incontinence rates were significantly higher in older patients after IPAA for CUC compared with younger patients. However, this did not contribute to a greater risk of pouch failure in these older patients. Patient sex and uncomplicated childbirth did not affect long-term functional outcomes.

Survival and functional outcome after prolonged intensive care unit stay.

OBJECTIVE: To examine the functional outcome and costs of a prolonged illness requiring a stay in the surgical intensive care unit (SICU) of 7 of more days. SUMMARY BACKGROUND DATA: The long-term benefits and costs after a prolonged SICU stay have not been well studied. METHODS: All patients with an SICU length of stay of 7 or more days from July 1, 1996, to June 30, 1997, were enrolled. One hundred twenty-eight patients met the entry criteria, and mortality status was known in 127. Functional outcome was determined at baseline and at 1, 3, 6, and 12 months using the Sickness Impact Profile score, which ranges from 0 to 100, with a score of 30 being severely disabled. Hospital costs for the index admission and for all readmissions to Johns Hopkins Hospital were obtained. All data are reported as median values. RESULTS: For the index admission, age was 57 and APACHE II score was 23. The initial length of stay in the ICU was 11 days; the hospital length of stay was 31 days. The Sickness Impact Profile score was 20.2 at baseline, 42.9 at 1 month, 36.2 at 3 months, and 20.3 at 6 months, and was lower than baseline at 1 year. The actual 1-year survival rate was 45.3%. The index admission median cost was $85,806, with 65 total subsequent admissions to this facility. The cost for a single 1-year survivor was $282,618 (1996). CONCLUSIONS: An acute surgical illness that results in a prolonged SICU stay has a substantial in-hospital death rate and is costly, but the functional outcome from both a physical and physiologic standpoint is compatible with a good quality of life.

Functional outcome of myositis patients: can a low-dose glucocorticoid regimen achieve good functional results?

OBJECTIVE: During the last few years, in an attempt to reduce the side effects of glucocorticoid (GC) therapy, we have been treating polymyositis-dermatomyositis (PM-DM) patients with a lower starting dose of GC than is classically recommended. In order to validate this approach, we performed a functional re-evaluation of these PM-DM patients. METHODS: A comprehensive protocol evaluating muscle strength, muscle function, CK levels, persistence of spontaneous activity on electromyography, disability in daily life activities and degree of dependence was applied in 25 non-cancer-associated biopsy-proven PM-DM patients, 15 of whom had been treated with a high-dose regimen (i.e. > 0.5 mg prednisolone/kg/day) and 10 with a low-dose regimen (i.e. < or = 0.5 mg prednisolone/kg/day). RESULTS: Our results indicate that the functional outcome of PM-DM patients given a low-dose starting regimen of GC does not differ from that observed in patients given higher doses. Interestingly, vertebral fractures were less common in patients treated with lower GC doses. CONCLUSIONS: Although our analysis has certain shortcomings, including the small number of patients investigated and their uncontrolled assignment to a low-dose or a high-dose GC regimen, the results of this retrospective study suggest that a low-dose starting regimen of GC can achieve a good functional outcome in PM-DM patients, with a reduction of treatment-related disability. This approach would be welcome as a step forward should it be validated by a longitudinal study.

Plasma homocysteine level and functional outcome of patients with ischemic stroke.

OBJECTIVE: To investigate the possible relationships between total plasma homocysteine level (tHcy) and functional outcome of stroke patients as evaluated by the FIM instrument. DESIGN: Retrospective chart analysis. SETTING: Inpatient stroke rehabilitation ward of a university-affiliated referral hospital. PARTICIPANTS: Consecutive patients (N=113) presenting with acute ischemic stroke. Patients were divided into 2 groups according to their tHcy levels (< or = 15 micromol/L, >15 micromol/L) and into 3 groups according to their FIM scores (low, < or =40; moderate, 41-80; high, >80). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The tHcy level was determined shortly after stroke onset by a high performance liquid chromatography method with fluorescence detection. Functional outcome was measured by the FIM instrument at admission and discharge. The tHcy level and FIM scores were obtained for all patients. Data outcomes were analyzed by t tests, 1-way analysis of variance, Mann-Whitney U, and Fisher exact tests, as well as by the 2 ordered polytomous logistic regression model. RESULTS: The 2 tHcy groups were similar in demographic, stroke, and comorbidity characteristics, differing only by higher frequency of hypertension in those with a tHcy greater than 15 micromol/L (51.7% vs 80.8%, respectively, P=.01). Compared with patients who had tHcy levels at 15 micromol/L or lower and were discharged from rehabilitation being in the highest FIM score group (>80), higher tHcy levels were not associated with a discharge FIM score of less than 40 (odds ratio [OR]=.77; 95% confidence interval [CI], 0.13-4.65; P=.77) or with a better functional outcome FIM score between 40 and 80 (OR=3.71; 95% CI, 0.73-18.99; P=.11). CONCLUSIONS: Our findings suggest that determination of tHcy level does not correlate with functional outcome in patients presenting for rehabilitation after acute ischemic stroke.

Anatomical and functional outcome of surgery of primary rhegmatogenous retinal detachment in high myopic eyes.

PURPOSE: To analyse the anatomical and functional outcome of surgery for primary rhegmatogenous retinal detachment (RRD) in highly myopic eyes. METHODS: We retrospectively reviewed the medical records of 111 high myopic patients (111 eyes) with primary RRD treated by scleral buckling or pars plana vitrectomy in a tertiary referral university hospital. The postoperative retinal status and best-corrected visual acuity were recorded. Risk factors including age, refractive error, duration of retinal detachment, preoperative visual acuity, extent of detachment, and intraoperative and postoperative complications were evaluated. Multiple logistic regression analysis was used to determine the independent correlation of each variable on anatomical and functional outcome. RESULTS: Primary surgery resulting in retinal reattachment was achieved in 96 (86.5%) eyes with more than 6 months follow-up (range, 6-60 months). Sixty-eight (61.3%) eyes had postoperative corrected visual acuity 20/50 or more. Postoperative complications in high myopic eyes were variable, and the most common was cataract progression (19.8%). Upon multiple logistic regression analysis, young patients had significantly better anatomical outcome, although the variables including less refraction error, better preoperative visual acuity, scleral buckling procedure, and less surgical intervention showed better functional outcome in our series. CONCLUSIONS: The anatomical outcome of surgery for primary RRD in highly myopic eyes was favourable, and young patients tended to have a higher success rate. Functional outcome was significantly correlated with refractive error, preoperative visual acuity, surgical procedure, and number of vitreoretinal surgery.

Establishing prognosis and maximizing functional outcomes after spinal cord injury: a review of current and future directions in rehabilitation management.

STUDY DESIGN: Review article. OBJECTIVES: To review the medical literature and provide a framework for predicting neurorecovery and functional outcomes after spinal cord injury based on injury severity. SUMMARY OF BACKGROUND DATA: The ability to accurately predict the magnitude of neurorecovery and expected functional outcomes after spinal cord injury is of great importance. This information is needed to justify medical and rehabilitation interventions to third party payers as well as to begin the process of planning for postdischarge care. Over the past several decades, significant progress has been made in accurately predicting neurorecovery and its impact on functional outcomes. METHODS: Structured review of published reports obtained through MED-LINE search and texts. RESULTS/CONCLUSION: Within 72 hours to 1 month after a spinal cord injury, it is possible to predict with reasonable accuracy the magnitude of expected recovery based on physical examination. The impact of motor level on long-term functional outcomes is also clear and has remained relatively unchanged for several decades. Functional outcomes are likely to improve in upcoming years as novel interventions, such as drugs and functional neuromuscular stimulation, are developed with the goals of limiting secondary injury and restoring neurologic function. New training methods, such as body weight support, that use activity-dependent neuroplasticity will also have a more prominent role.

Determinants of functional outcome after revascularization for critical limb ischemia: an analysis of 1000 consecutive vascular interventions.

BACKGROUND: When reporting standards for successful lower extremity revascularization were established, it was assumed that arterial reconstruction, patency, and limb salvage would correlate with the ultimate goal of therapy: improved functional performance. In reality, factors determining improvement of ambulation and maintenance of independent living status after revascularization have been poorly studied. The purpose of this study was to assess the important determinants of functional outcome for patients after intervention for critical limb ischemia. METHODS: The results of 1000 revascularized limbs from 841 patients were studied. Indications were rest pain, 41.1%; ischemic ulceration, 35.6%; gangrene, 23.3%; infrainguinal, 70.9%; aortoiliac, 24.2%; and both, 4.9%. Treatment was by endovascular intervention, 35.5%; open surgery, 61.7%; and both, 2.8%. Patient were mean age of 68 +/- 12 years, and 56.6% were men, 74.7% were white, 54.2% had diabetes mellitus, 67% were smokers, 13.4% had end-stage renal disease and were on dialysis, and 36% had prior vascular surgery. Patients were treated with conventional therapy by fellowship-trained vascular specialists at a single center and were analyzed according to the type of intervention, the arterial level treated, age, race, gender, presentation, the presence of diabetes, smoking history, end-stage renal disease, coronary disease, hypertension, hyperlipidemia, obesity, chronic obstructive pulmonary disease, previous stroke, dementia, prior vascular surgery, preoperative ambulatory status, limb loss <or=1 year of treatment, and independent living status. The technical outcomes of reconstruction patency and limb salvage as well as the functional outcomes of survival, maintenance of ambulation, and independent living status were measured for each variable using Kaplan-Meier life-table analysis, and differences were assessed using the log-rank test. A Cox proportional hazards model was used to assess independent predictors of outcome and obtain adjusted hazard ratios and 95% confidence intervals. RESULTS: At 5 years, 72.4% of the entire cohort had a patent reconstruction and 72.1% had an intact limb. Overall 5-year functional outcomes were 41.9% for survival, 70.6% for maintenance of ambulation, and 81.3% for independent living status. Outcome was not significantly affected by the type of treatment (endovascular or open surgery) or by the level of disease treated (aortoiliac, infrainguinal, or both). The most important independent, statistically significant predictors of particularly poor functional outcome were impaired ambulatory ability at the time of presentation (70% 5-year mortality, hazard ratio, 3.34; 39.5% failure to eventually ambulate, hazard ratio, 2.83; 30% loss of independent living status, hazard ratio, 7.97), and the presence of dementia (73% late mortality, hazard ratio, 1.57; 41.2% failure to eventually ambulate, hazard ratio, 2.20; 46.4% loss of independent living status, hazard ratio, 5.44). These factors were even more predictive than limb amputation alone. CONCLUSION: Functional outcome for patients undergoing intervention for critical limb ischemia is not solely determined by the traditional measures of reconstruction patency and limb salvage, but also by certain intrinsic patient comorbidities at the time of presentation. These findings question the benefit of our current approach to critical limb ischemia in functionally impaired, chronically ill patients--patients who undoubtedly will be more prevalent as our population ages.

Improved functional outcome after spinal cord injury in iNOS-deficient mice.

STUDY DESIGN: Functional outcome was evaluated following experimental compression-type spinal cord injury (SCI) in wild-type mice and knockout mice, lacking the inducible nitric oxide synthase (iNOS) gene. OBJECTIVES: To evaluate the role of the nitric oxide generating enzyme iNOS in SCI. METHODS: The experimental animals were subjected to an extradural compression of the thoracic spinal cord. Functional outcome was studied during the first 2 weeks post-injury using a scoring system for assessment of hind limb motor function. RESULTS: Injury resulted in initial paraplegia followed by gradual improvement of motor function in most cases. Mice lacking the iNOS gene (iNOS-/-) clearly tended to have a better functional outcome than wild-type mice. The difference was significant on day 14 after injury. CONCLUSION: In accordance with a few earlier experimental studies, showing beneficial effects of pharmacological iNOS inhibition, the present report would indicate a destructive influence of iNOS following spinal cord trauma.

The functional outcome of children after a burn injury: a pilot study.

Assessment of functional outcome can be used as a measure of the effectiveness of intervention during recovery from a burn injury. This pilot study identifies the factors that are likely to be most important for determining standardized functional outcome measures for children after a burn injury; it highlights the contribution of these factors to variations in children's postburn outcomes. A focus group of 8 parents and a self-report questionnaire administered to 12 children and 13 parents were the means of obtaining information for this exploratory study. Itching was found to be one of the primary impairments that contributed to reduced functional outcome during skin healing after a burn injury. The activities of children who had been burned that were most frequently affected by the injury (as reported by parents) were schoolwork and sports; these were closely followed by sleeping, playing with other children, and unliked activities. Least affected activities were enjoying the family, eating, seeing friends, watching television, and bathing or showering. Eighty-five percent of parents reported at least some level of interference with the listed daily activities. Burn injuries are likely to cause interference with several aspects of a patient's daily life. As a result, families require ongoing support and monitoring. Further research should longitudinally compare the performance of children who have been burned with other children and adolescents.

Operative correction of adolescent idiopathic scoliosis in male patients. A radiographic and functional outcome comparison with female patients.

BACKGROUND: The outcomes following surgical treatment of adolescent idiopathic scoliosis have traditionally been assessed on the basis of radiographic parameters and, more recently, functional outcome measures. However, we know of no published studies in which radiographic and functional outcomes following surgery were compared between male and female patients. METHODS: Fifty-two male patients who had had surgery for adolescent idiopathic scoliosis were compared retrospectively with two groups of female patients: a random sample of 130 female patients who had had surgical treatment for adolescent idiopathic scoliosis during the same time period and a subgroup of fifty-two of these female patients who had been matched to the male patients with regard to curve type and magnitude. Radiographic parameters were compared between the male and female patients, and the Scoliosis Research Society outcome questionnaire was used to compare functional results between the male patients and the matched female group. RESULTS: Compared with the random sample of female patients, the male patients were older at the time of presentation (average [and standard deviation], 13.9 +/- 1.9 compared with 12.8 +/- 1.4 years) and at the time of surgery (average, 15.9 +/- 2.0 compared with 14.2 +/- 1.4 years) (p < 0.05). The male and female patients presented with primary coronal curves of similar magnitudes (average, 48 degrees +/- 19 degrees compared with 47 degrees +/- 13 degrees ), but the male patients had larger curves at the time of surgery (average, 62 degrees +/- 11 degrees compared with 56 degrees +/- 10 degrees ) with greater coronal plane imbalance. Compared with the subset of female patients matched for curve type and magnitude, the male patients had, on average, a longer surgical time (263 +/- 61 compared with 202 +/- 40 minutes), greater intraoperative blood loss (1148 +/- 660 compared with 944 +/- 408 mL), and less curve correction in the coronal plane (from 62 degrees +/- 11 degrees to 31 degrees +/- 11 degrees compared with from 59 degrees +/- 10 degrees to 23 degrees +/- 9 degrees ) (p < 0.05). The loss of coronal plane correction, the final coronal balance, all measured sagittal plane parameters, and the prevalence of complications were the same in these two groups. With regard to functional outcome, the scores were similar with the exception that the male patients had lower scores in the category of "function from back condition" when compared with the matched female patients (3.8 +/- 0.2 compared with 4.3 +/- 0.3 points) (p < 0.05). CONCLUSIONS: Adolescent idiopathic scoliosis is identified at a later age in male patients than in female patients with similar curve types. The curve magnitudes in the male patients are greater at the time of surgery. When surgeons are planning operative correction of adolescent idiopathic scoliosis in male patients, they should expect longer operative time, greater blood loss, and less coronal plane correction of the primary curve. However, balance in the coronal and sagittal planes should be achieved and complication rates and functional outcomes can be expected to be similar to those in female patients.

Protein S-100b for individual prediction of functional outcome in spinal epidural empyema.

STUDY DESIGN: A study correlating protein S-100b serum levels with postoperative functional outcome in patients with spinal cord compression resulting from epidural empyema. OBJECTIVES: To evaluate the potential value of protein S-100b for prediction of individual functional outcome in medullary lesions resulting from spinal epidural empyema. SUMMARY OF BACKGROUND DATA: Despite modern medical advances, a reliable individual prediction of functional outcome in case of spinal epidural empyema is still not possible. METHODS: Forming two outcome groups, clinical outcome following surgery was considered to be favorable in case of neurologic improvement with preservation or retrieval of walking ability, whereas nonimprovement without restoration of gait function was regarded to be unfavorable. Venous blood samples for protein S-100b were taken from all patients immediately after admission and regularly after operative decompression. Initial levels of S-100b were correlated with preoperative degree and duration of paresis, and the individual time course of S-100b measurements was correlated with clinical outcome. RESULTS: The initial level of protein S-100b is not correlated with preoperative degree and duration of paresis or with functional outcome. The individual time course of S-100b measurements, however, is different in both outcome groups. Levels of protein S-100b that were either always normal or that were initially increased but normalized rapidly within 3 days were invariably associated with retrieval of gait function, whereas none of those patients recovered in whom increased levels of S-100b persisted beyond the third postoperative day (P < 0.003). CONCLUSIONS: Protein S-100b might be a promising serum marker with prognostic significance in the event of spinal cord compression resulting from epidural empyema.

Prognostic value of the Island sign for hematoma expansion and functional outcome after intracerebral hemorrhage: a systematic review and meta-analysis.

PURPOSE: The Island Sign (IS) is a radiological finding observed in patients with intracerebral hemorrhage (ICH). This meta-analysis aimed to evaluate the association between IS and both hematoma expansion (HE) and functional outcomes by comparing ICH patients with and without IS. METHODS: We searched PubMed, Embase and Cochrane Library for studies of intracerebral hemorrhage reporting the IS. The primary outcomes were functional status and hematoma expansion, secondary outcome was mortality. Statistical analysis was performed using RStudio, effect sizes were calculated as odds ratios (ORs) with 95% confidence interval (95% CIs), and heterogeneity was assessed with I2 statistics. In addition, meta-regression and sensitivity analyses were performed, and publication bias was assessed through funnel plots and Egger's regression test. RESULTS: We included 21 observational studies with a total of 9,459 patients with spontaneous ICH, 1,769 of them had IS, while 7,690 did not. The mean age was 63.5 ± 13.2 and 5,835 (61.7%) were male. Poor functional outcomes (OR 2.77, 95% CI: 2.14-3.58, p < 0.0001, I2 = 4.9%) and hematoma expansion (OR 2.75, 95% CI: 1.87-4.03, p < 0.0001, I2 = 77.4%) were substantially higher in patients with IS, as well as the overall mortality rate (OR 2.54, 95% CI: 1.55-4.17, p = 0.0002, I2 = 0%). Meta-regression analysis showed no statistically significant association between imaging-related timing variables and hematoma expansion. Furthermore, the leave-one-out sensitivity analyses showed that no single study exerted a disproportionate influence on the overall effect for the examined outcomes, and Egger's linear regression tests were not statistically significant for both outcomes. CONCLUSION: Patients with the Island Sign are associated with higher rates of poor functional outcomes and hematoma expansion. Thus, IS is a relevant radiological finding with potential to support early risk stratification and optimize patient management and treatment selection.

Longitudinal studies of cognition and functional outcome in schizophrenia: implications for MATRICS.

It is generally accepted that cognitive deficits in schizophrenia are related to functional outcome. However, support for longitudinal relationships between cognition and functional outcome has not been as well documented. The current paper presents a review of 18 recently published longitudinal studies (minimum 6-month follow up) of the relationships between cognition and community outcome in schizophrenia. Results from these studies reveal considerable support for longitudinal associations between cognition and community outcome in schizophrenia. These studies demonstrate that cognitive assessment predict later functional outcome and provide a rationale for psychopharmacological interventions for cognitive deficits in schizophrenia. Although the relationships between cognition and community outcome are well-supported, it is clear that community functioning is also affected by a host of factors apart from cognition that are usually not considered in clinical trial studies (e.g., psychosocial rehabilitation and educational/vocational opportunities). In the second part of the paper, we consider intervening steps between cognitive performance measures and community outcome. These steps are apt to have important implications for clinical trials of cognition-enhancing agents in schizophrenia.

Does increasing age have a negative impact on six-month functional outcome after coronary artery bypass?

BACKGROUND: Advances in medical care and improvements in catheter-based interventions for coronary artery disease have advanced the age at which patients present for coronary artery bypass graft (CABG) operations. The impact of age on functional outcome after CABG is unclear. METHODS: Functional outcome was assessed at baseline and at 6 months using the Duke Activity Status Index (DASI) in 337 consecutive patients undergoing primary or redo CABG. Complete functional outcome data were available in 292 patients (86%). RESULTS: The mean baseline DASI score was significantly lower in patients > or = 70 years of age (24.8 +/- 14.5 vs 30.9 +/- 17.8, P =.002) and at 6 months (29.6 +/- 16.5 vs 38.0 +/- 17.1, P =.0001); however, the 6-month change in DASI score (7.2 +/- 17.5 in patients < 70 years of age vs 4.9 +/- 14.0 in patients > or = 70 years of age, P =.23) was comparable. When examined in terciles of age, the 6-month change in DASI score was not significantly different (P =.11) in patients aged 31 to 60 years (5.8 +/- 18.0), aged 61 to 71 years (8.7 +/- 15.7), or aged 72 to 91 years (4.0 +/- 14.6). CONCLUSIONS: These functional outcome results demonstrate that older patients present for CABG at a significantly lower functional level and remain at a significantly lower functional level 6 months after CABG. However, the functional improvement after CABG is not significantly different across age groups.
