Longitudinal recovery of executive functions and social participation prediction following traumatic brain injury

There is heterogeneity across studies and a lack of knowledge about recovery of EFs over time following traumatic brain injury (TBI). Also, EFs are associated with functional outcome, but there is still a gap in knowledge concerning the association between EFs and social participation following TBI. For this reason, we aim to (1) measure the recovery of the three executive function subcomponents of Miyake's model, namely flexibility, updating and inhibition between the acute phase (T1) and 6 months post TBI (T2) and (2) measure the relationship between EFs and social participation after TBI. Thus, a prospective longitudinal study that included 75 patients with TBI (mild and moderate-severe) and 50 patients with orthopedic injuries (controls) without brain damage was carried out. An extensive EFs test battery was administered at T1 and T2 whereas the Mayo-Portland Adaptability Inventory-4 (MPAI-4) was administered only at T2. In contrast with the controls, both TBI groups improved significantly between T1 and T2 on WMS-III Mental Control test (MC) and the D-KEFS Category Switching Condition of the Verbal Fluency task (SVF). Results also showed a simple time effect for the WAIS-IV Digit span and the Hayling tests. Moreover, there was an association between the SVF test and social participation (MPAI-4) at T2. In conclusion, the MC and SVF tests were found to be the best tools for measuring recovery of EFs following TBI. The SVF test was the most likely measure of EFs to give the neuropsychologist an idea of the patient's social participation.

Dancers' Perceptions of Accessibility and Quality of the Relationship with Healthcare Professionals in Quebec

OBJECTIVE

To understand dancers' perception of accessibility to care and quality of the relationship with healthcare practitioners in Quebec; to identify the key elements of an optimal dancer-physician relationship; and to propose recommendations for improvement.

METHODS

An online questionnaire consisting of multiple choice, "yes/no," and short answer questions was sent to professional dance organizations, companies, agencies, and schools in Quebec, Canada. Information regarding the dance artists' sociodemographics, dance background, dance-related injuries, and access to a primary care physician were collected. Experiences and expectations regarding the dancer-physician relationship were surveyed. One-way ANOVA analyses and Pearson correlations were performed to assess differences of perception between dancers' demographic characteristics and associations between the variables.

RESULTS

Out of 161 participants, 144 met inclusion criteria, consisting of largely French-speaking females, North American or European decent, self-employed contemporary dancers with an average age of 33.13 ± 10.81 yrs. Dance artists sought medical care from osteopaths (47.9%) and physiotherapists (36.1%) more frequently than from physicians (8.3%). Fully employed dancers had more favorable perceptions of the dancer-physician relationship compared to self-employed dancers and those who had mixed streams of income. The perception of most participants was that physicians do not comprehend the unique dance-associated impacts on health (81.8%). The most important aspect affecting perception of the relationship with the physician was diagnostic acumen (41.3%). Most participants (79.0%) selected "works with other health professionals [...] and gives expert advice" as an important expectation from physicians.

CONCLUSION

This research is the first investigation of the dancer-physician relationship in Quebec. It reveals a desire amongst the dance artist community to improve the dancer-physician relationship and the overall quality of their unique healthcare requirements.

Brain stimulation in attention deficits after traumatic brain injury: a literature review and feasibility study

BACKGROUND

After a traumatic brain injury, disturbances in the attentional processes have a direct negative effect on functional recovery and on return to complex activities. To date, there is no good attention remediation treatment available. The primary objective of this review and pilot study is to provide an overview of the research evidence and to evaluate the feasibility of implementing a tDCS protocol to improve attention disorders in patients with mild complicated to severe subacute TBI, hospitalized in an inpatient rehabilitation facility. Our secondary objective is to extract preliminary data and observational information on participants' response to treatment.

METHODS

Participants were recruited from a consecutive series of patients admitted to the TBI unit of a subspecialized regional rehabilitation center. They received a 20-min tDCS stimulation 3 times a week for 3 weeks. A neuropsychological evaluation was performed before and after the intervention. We collected participants' sociodemographic and clinical characteristics as well as information about satisfaction, tolerability, and adverse effects.

RESULTS

One hundred sixty-four patients were admitted between September 2018 and January 2020. One hundred fifty-eight were excluded, and 6 patients with presumed attentional deficits were enrolled. None completed the protocol as intended. No major side effects occurred.

CONCLUSION

Non-invasive brain neurostimulation is promising to enhance attention deficits in patients with TBI. Implementation of a tDCS protocol to fulfill this purpose in an intensive inpatient rehabilitation center has its limitations. We made recommendations to facilitate the implementation of similar projects in the future.

Societal cost of traumatic brain injury: A comparison of cost-of-injuries related to biking with and without helmet use

OBJECTIVE

The goal of this study is to determine if a difference in societal costs exists from traumatic brain injuries (TBI) in patients who wear helmets compared to non-wearers.

METHODS

This is a retrospective cost-of-injury study of 128 patients admitted to the Montreal General Hospital (MGH) following a TBI that occurred while cycling between 2007-2011. Information was collected from Quebec Trauma Registry. The independent variables collected were socio-demographic, helmet status, clinical and neurological patient information. The dependent variables evaluated societal costs.

RESULTS

The median costs of hospitalization were significantly higher (p = 0.037) in the no helmet group ($7246.67 vs. $4328.17). No differences in costs were found for inpatient rehabilitation (p = 0.525), outpatient rehabilitation (p = 0.192), loss of productivity (p = 0.108) or death (p = 1.000). Overall, the differences in total societal costs between the helmet and no helmet group were not significantly different (p = 0.065). However, the median total costs for patients with isolated TBI in the non-helmet group ($22, 232.82) was significantly higher (p = 0.045) compared to the helmet group ($13, 920.15).

CONCLUSION

Cyclists sustaining TBIs who did not wear helmets in this study were found to cost society nearly double that of helmeted cyclists.

Transforaminal versus intra-articular facet corticosteroid injections for the treatment of cervical radiculopathy: a randomized, double-blind, controlled study

BACKGROUND AND PURPOSE

Transforaminal corticosteroid injections can be performed in the management of cervical radiculopathy but carry the risk of catastrophic complications. This study compares the efficacy of transforaminal and facet corticosteroid injections at 4 weeks' follow-up.

MATERIALS AND METHODS

We randomly assigned 56 subjects to receive CT-guided transforaminal (15 men, 13 women; mean age, 52 years; range, 28-72 years) or facet (8 men, 20 women; mean, 44 years; range, 26-60 years) injections. The primary outcome was pain severity rated on a Visual Analog Scale (0-100). Secondary outcomes were the Neck Disability Index and the Medication Quantitative Scale.

RESULTS

In the intention-to-treat and as-treated analyses, for a mean baseline score, facet injections demonstrated a significant pain score reduction of 45.3% (95% CI, 21.4-69.2) and 37.0% (95% CI, 9.2-64.7), while transforaminal injections showed a nonsignificant pain score reduction of 9.8% (95% CI, +11.5-31.2) and 17.8% (95% CI, +6.6-42.2). While facet injections demonstrated an improvement in the Neck Disability Index score of 24.3% (95% CI, +2.9-51.5) and 20.7% (95% CI, +6.2-47.6) as opposed to transforaminal injections of 9.6% (95% CI, +15.2-34.4) and 12.8% (95% CI, +11.2-36.7), the results were not statistically significant. Noninferiority of facet to transforaminal injections was demonstrated for baseline pain scores of ≤60, while noninferiority analysis was inconclusive for baseline pain scores of ≥80 and for the Neck Disability Index. Neither intervention showed a significant medication-intake score reduction with time.

CONCLUSIONS

Facet injections are effective for the treatment of cervical radiculopathy and represent a valid and safer alternative to transforaminal injections.

Global outcome in acute phase of treatment following moderate-to-severe traumatic brain injury from motor vehicle collisions vs assaults

PRIMARY OBJECTIVE

To compare socio-demographic, medical characteristics and acute outcomes between patients with traumatic brain injuries (TBIs) from motor vehicle collision (MVC) or assault in an acute care setting.

RESEARCH DESIGN

This descriptive, comparative retrospective cohort study included 415 patients with moderate and severe TBI secondary to an assault (n¼91) vs a motor vehicle collision (n=324).

METHODS AND PROCEDURES

Outcome measures were length of stay (LOS) in the intensive care unit and in hospital, Extended Glasgow Outcome Scale (GOS-E), FIM® instrument (‘FIM’) and discharge destination.

MAIN OUTCOMES AND RESULTS

Patients with TBI from MVC had a higher percentage of polytrauma, higher injury severity scores, required more orthopaedic surgeries and thoracic drain insertions. Patients with TBI from assault were more often non-Caucasian, young single men, less educated with higher unemployment rates and criminal records, with a history of alcohol and drug abuse and were more often intoxicated on admission. There was no significant group difference in the LOS and FIM ratings, but patients with assault-related TBI were more often discharged home and had a more favourable GOS-E.

CONCLUSION

Variables such as injury severity, age, level of intoxication on admission and presence of surgeries should be considered when determining acute outcome.
