Spasticity Predicts Motor Recovery for Patients with Subacute Motor Complete Spinal Cord Injury.

OBJECTIVE: A motor complete spinal cord injury (SCI) results in the loss of voluntary motor control below the point of injury. Some of these patients can regain partial motor function through inpatient rehabilitation; however, there is currently no biomarker to easily identify which patients have this potential. Evidence indicates that spasticity could be that marker. Patients with motor complete SCI who exhibit spasticity show preservation of descending motor pathways, the pathways necessary for motor signals to be carried from the brain to the target muscle. We hypothesized that the presence of spasticity predicts motor recovery after subacute motor complete SCI. METHODS: Spasticity (Modified Ashworth Scale and pendulum test) and descending connectivity (motor evoked potentials) were tested in the rectus femoris muscle in patients with subacute motor complete (n = 36) and motor incomplete (n = 30) SCI. Motor recovery was assessed by using the International Standards for Neurological Classification of Spinal Cord Injury and the American Spinal Injury Association Impairment Scale (AIS). All measurements were taken at admission and discharge from inpatient rehabilitation. RESULTS: We found that motor complete SCI patients with spasticity improved in motor scores and showed AIS conversion to either motor or sensory incomplete. Conversely, patients without spasticity showed no changes in motor scores and AIS conversion. In incomplete SCI patients, motor scores improved and AIS conversion occurred regardless of spasticity. INTERPRETATION: These findings suggest that spasticity represents an easy-to-use clinical outcome that might help to predict motor recovery after severe SCI. This knowledge can improve inpatient rehabilitation effectiveness for motor complete SCI patients. ANN NEUROL 2023.

Occupational Therapy for People with Early Parkinson's Disease: A Retrospective Program Evaluation.

Purpose: Clinical practice guidelines establish that occupational therapy (OT) services are indicated for people with early Parkinson's disease (PD). However, OT is uncommon compared to other rehabilitation services. This study describes the development and evaluation of a proactive, consultative OT program for people with early PD as a part of an integrated care approach. Materials and Methods: The program was developed by an occupational therapist adapting practice guidelines for people with early PD. Retrospective program evaluation occurred at an outpatient rehabilitation clinic. The consultative OT program for early PD includes a 90-minute evaluation with instruction in self-management techniques, individually tailored exercises, and follow-up recommendations. The program was evaluated with the RE-AIM framework. Postprogram semistructured interviews provided patient-reported program effectiveness and satisfaction. Results: In 2018, 23 individuals used OT out of 77 people with early PD who attended the proactive rehabilitation program. Most individuals (n = 16, 69.6%) were within Hoehn and Yahr stages 1-2 and were seen within 3 years of PD diagnosis. Participants presented with deficits in hand strength (60.0 ± 23.4 pounds) and dexterity (right hand 30.0 ± 8.0 seconds) and reported complaints about basic and/or instrumental activities of daily living (n = 15, 65.2%). Semistructured interviews (n = 16) revealed that most individuals (75%) reported high satisfaction. Of the 10 who recalled a home exercise program, 60% reported continued adherence. Consultative OT was delivered with fidelity in 22/23 individuals (96%). After one year, only two occupational therapists at one clinic had adopted the program, and the program is maintained in the organization. Conclusion: Occupational therapists reached people in the early stages of PD when a specific program was tailored to evaluate and target their specific needs. Motor activity deficits noted in individuals with early PD support future scaling and sustainability efforts of OT within this population. Quality improvement suggestions are discussed for future implementation and clinical trials.

Angiography versus FFR guided complete revascularization versus culprit-only revascularization for patients presenting with STEMI: Network meta-analysis.

This study aimed to compare the outcomes of different revascularization strategies among patients presenting with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease (MVD) undergoing primary percutaneous coronary intervention (PCI). MVD is present in about one-half of patients presenting with STEMI. Despite several randomized controlled trials (RCTs) comparing complete revascularization (CR) and culprit-only revascularization (COR), the optimal PCI strategy for STEMI patients with MVD remains unsettled. Moreover, it is unclear whether angiography-guided CR or fractional flow reserve (FFR)-guided CR is associated with better outcomes. PubMed, Scopus, and Cochrane Library were searched for RCTs comparing CR strategies with COR strategy in patients with STEMI between January 1, 2000 and September 30, 2021 were identified. A frequentist network meta-analyses were performed for three PCI strategies: (1) COR; (2) angiography-guided CR; and (3) FFR-guided CR. Ten RCTs including 7979 patients were included. A strategy of angiography-guided CR or FFR-guided CR was associated with a significantly lower rate of major adverse cardiac events (MACE) and unplanned revascularization compared with COR. Although there were no statistical significant difference between angiography-guided CR and FFR-guided CR, P score analysis showed that angiography-guided CR was ranked as the best strategy for reducing MACE, all-cause mortality, cardiovascular death, recurrent myocardial infarction, and unplanned revascularization. In patients presenting with STEMI and MVD undergoing primary PCI, angiography-guided CR or FFR-guided CR improve outcomes compared with COR. Furthermore, the strategy of angiography-guided CR ranked as the best revascularization strategy in those patients.

Impact of Left Ventricular Systolic Function After Moderate-to-Severe Isolated Traumatic Brain Injury: A Systematic Review and Meta-Analysis.

Traumatic brain injury (TBI) can result in left ventricular dysfunction, which can lead to hypotension and secondary brain injuries. However, the association between left ventricular systolic dysfunction (LVSD) and in-hospital mortality in patients with moderate-to-severe isolated TBI is controversial. Therefore, we conducted a systematic review and meta-analysis to identify the prevalence of LVSD and evaluate whether LVSD following moderate-to-severe isolated TBI increases the in-hospital mortality. We searched PubMed, EMBASE, and the Cochrane Library database from January 1, 2010, through June 30, 2020. Meta-analysis was performed to determine the incidence of LVSD and related mortality in patients with moderate-to-severe isolated TBI. A systematic review identified 5 articles appropriate for meta-analysis. The total number of patients pooled was 256. LVSD was reported in 4 studies, of which the estimated incidence of patients with LVSD was 18.7% (95% confidence interval, 11.9-26.6). Five studies reported on in-hospital mortality, and the estimated in-hospital mortality was 14.1% (95% confidence interval, 5.3-25.6). Finally, 3 studies were eligible for analyzing the association of LVSD and in-hospital mortality. On meta-analysis, in-hospital mortality was significantly higher in patients with LVSD (risk ratio, 6.57; 95% confidence interval, 3.71-11.65; P < 0.001). In conclusion, LVSD after moderate-to-severe TBI is common and may be associated with worse in-hospital outcomes.

Fluorescein-Guided Resection of High Grade Gliomas: A Meta-Analysis.

BACKGROUND: High-grade gliomas (HGGs) have a poor prognosis despite current standard of care of surgery, chemotherapy, and radiation therapy. Achieving gross total resection (GTR) has been found to prolong survival in these patients. Intraoperative fluorescent agents are often used to aid in the resection of HGGs. One commonly used fluorescent agent is fluorescein sodium, which is U.S. Food and Drug Administration-approved for ocular surgeries and has a better side effect profile and is less costly than 5-aminolevulinic acid (5-ALA). In this meta-analysis, we provide statistical evidence of the efficacy in using fluorescein for HGG resection. METHODS: Following the PRISMA framework, we assessed 119 reports from PubMed, Medline (Ovid), and BIOSIS Citation Index and found 21 eligible studies for meta-analysis, assessing the rates of GTR with fluorescein-guided resection of HGGs. RESULTS: A pooled cohort of 336 patients underwent fluorescein-guided HGG resection with a GTR rate of 81% (95% confidence interval 73%-89%; P < 0.001). Ten case-controlled studies were analyzed, showing a 29.5% increase in GTR rate in the fluorescein group compared with non-fluorescein-guided surgeries. CONCLUSIONS: This meta-analysis shows that fluorescein-guided surgery improves GTR rates of HGGs when compared with non-fluorescence guided surgery and has similar GTR rates when compared with reported 5-ALA-guided resection rates.

Impact of systematic cavity shave margins in breast-conserving surgery at a large community hospital with a low baseline re-excision rate.

Systematic cavity shave margins (CSM) can decrease rate of positive margins and re-excision beyond that of selective CSM. The objective of this study was to determine whether systematic CSM decreased re-excision rate in a population with a low baseline re-excision rate. We conducted a retrospective chart review of patients who underwent breast-conserving surgery (BCS) from November 2013 to November 2017. Primary end points were re-excision rate and margin status. Secondary end points were total volume of tissue excised, operative time, and concordance of core needle biopsy (CNB) pathology with final surgical pathology. The re-excision rates were 14.29% in the no shave margin group; 15.38% in the selective CSM; and 14.59% in the systematic CSM (P = .985). Odds of re-excision with ductal carcinoma in situ (DCIS) was 5.04 times greater than with invasive cancer (INV) and 1.94 times higher than with INV and DCIS. There was no significant difference in positive margins between groups (P = .362). Mean specimen volume was lowest in the systematic CSM group (64.6 cm3 ), compared to no CSM and selective CSM (94.6 cm3 and 91.8 cm3 , respectively). With inclusion of shave margin volumes, total volume removed was not significantly different between no shave margin group (94.6 cm3 ) and systematic CSM (89.7 cm3 ) (P = .949). For patients with invasive ductal carcinoma (IDC) alone on their initial biopsy pathology, 69% were discovered to also have DCIS upon final pathology. Re-excision rate and specimen volume between all groups were not statistically different. There was a higher re-excision rate when DCIS was present, especially when not identified on CNB. As systematic CSM is most impactful when DCIS is involved, it is important to establish its presence for proper surgical planning.
