Characteristics of Pediatric Mild Traumatic Brain Injury and Recovery in a Concussion Clinic Population.

ABSTRACT: Importance:Pediatric mild traumatic brain injury (TBI) and concussion are a public health challenge with up to 30% of patients experiencing prolonged recovery. Pediatric patients presenting to concussion clinics often have ongoing impairments and may be at increased risk for persistent symptoms. Understanding this population is critical for improved prognostic estimates and optimal treatment. Objective:To describe pediatric patients presenting to concussion clinics and characterize factors associated with their recovery. Design, Setting, and Participants:This prospective cohort study included patients enrolled at multicenter concussion specialty clinics from the Four Corners Youth Consortium from December 2017 to July 2019, with up to 12-month follow-up. Patients were eligible if they were aged 5 to 18.99 years with a diagnosis of mild TBI or concussion presenting to participating clinics within 8 weeks of injury. Patients were excluded if the patient or their parents were unable to read or sign the consent document, or if the patient had a Glasgow Coma Scale score less than 13 or a penetrating injury. Data were analyzed from February 2019 to April 2020. Exposures:Diagnosis of mild TBI or concussion. Main Outcomes and Measures:This study used National Institute of Neurological Disorders and Stroke common data elements, including data on demographic characteristics, injury details, history, neurological and neuropsychological assessments, and treatment. Results:A total of 600 patients were consecutively enrolled, among whom 324 (54.0%) were female and 435 (72.5%) were adolescents (ie, aged 13-18 years). A higher proportion of girls and women (248 patients [76.5%]) were adolescents compared with boys and men (187 patients [67.8%]) (P?=?.02), and girls and women reported significantly more preexisting anxiety compared with boys and men (80 patients [26.7%] vs 46 patients [18.7%]; P?=?.03). Significantly more adolescents reported preexisting migraines compared with preadolescents (82 patients [20.9%] vs 15 patients [10.9%]; P?=?.01). Girls and women recovered more slowly than boys and men (persistent symptoms after injury: week 4, 217 patients [81.6%] vs 156 patients [71.2%]; week 8, 146 patients [58.9%] vs 89 patients [44.3%]; week 12, 103 patients [42.6%] vs 58 patients [30.2%]; P?=?.01). Patients with history of migraine or anxiety or depression recovered more slowly than those without, regardless of sex. Conclusions and Relevance:These findings suggest that identification of subgroups of pediatric patients with mild TBI or concussion at risk for prolonged recovery could aid in better prognostic estimates and more targeted treatment interventions.

Project description:IntroductionMild traumatic brain injury (mTBI) is a complex injury with heterogeneous physical, cognitive, emotional and functional outcomes. Many who sustain mTBI recover within 2 weeks of injury; however, approximately 10%-20% of individuals experience mTBI symptoms beyond this 'typical' recovery timeframe, known as persistent post-concussion symptoms (PPCS). Despite increasing interest in PPCS, uncertainty remains regarding its prevalence in community-based populations and the extent to which poor recovery may be identified using early predictive markers.Objective(1) Establish a research dataset of people who have experienced mTBI and document their recovery trajectories; (2) Evaluate a broad range of novel and established prognostic factors for inclusion in a predictive model for PPCS.Methods and analysisThe Concussion Recovery Study (CREST) is a prospective, longitudinal observational cohort study conducted in Perth, Western Australia. CREST is recruiting adults aged 18-65 from medical and community-based settings with acute diagnosis of mTBI. CREST will create a state-wide research dataset of mTBI cases, with data being collected in two phases. Phase I collates data on demographics, medical background, lifestyle habits, nature of injury and acute mTBI symptomatology. In Phase II, participants undergo neuropsychological evaluation, exercise tolerance and vestibular/ocular motor screening, MRI, quantitative electroencephalography and blood-based biomarker assessment. Follow-up is conducted via telephone interview at 1, 3, 6 and 12 months after injury. Primary outcome measures are presence of PPCS and quality of life, as measured by the Post-Concussion Symptom Scale and the Quality of Life after Brain Injury questionnaires, respectively. Multivariate modelling will examine the prognostic value of promising factors.Ethics and disseminationHuman Research Ethics Committees of Royal Perth Hospital (#RGS0000003024), Curtin University (HRE2019-0209), Ramsay Health Care (#2009) and St John of God Health Care (#1628) have approved this study protocol. Findings will be published in peer-reviewed journals and presented at scientific conferences.Trial registration numberACTRN12619001226190.

Project description:BACKGROUND:The American Congress of Rehabilitation Medicine (ACRM) in 2010 called for more head injury research on gender disparities to bridge the gender gap for the short-and long-term effects of TBI, including sexual and reproductive outcomes. In this paper, we review the state of the literature before and after the ACRM announcement, and evaluate how research teams have considered females and mildly injured TBI(mTBI)/concussion groups in post-TBI-related changes in sexual functioning. METHODS:The research question for this scoping review was "what is the state of the literature in the evaluation of post-TBI sexual changes for women, and individuals with mTBI?" Using the 2010 ACRM call for action as a line of demarcation, we compared our findings before and after the 2010 announcement. RESULTS:We identified 9 research studies that addressed sexual functioning changes in females and mTBI/concussion groups. Four of the nine were published before the 2010 ACRM announcement, and five were published after. The representation of female research participants increased steadily over the 28-year timespan. The proportion of individuals with mTBI included in the post-2010 era was higher than the earlier time period. Consistently, women with mTBI reported more adverse sexual outcomes compared to male cohorts, orthopaedic, and non-injured comparison groups. This observation persisted regardless of recruitment site (rehabilitation center/Emergency Department (ED)/Community) or time of outcome assessment (acute versus chronic). The findings also remained despite the heterogeneity of survey questionnaires used to evaluate sexual functioning outcomes. Excluding the most recent 2019 study, none of the research groups compared the findings by TBI severity, making it difficult to fully understand how concussion-related sexual changes compare to more severe forms of the head injury. The long term impacts of the sexual changes, such as infertility and relationship discord were also absent across all studies; even though most evaluated outcomes chronically (some as far out as 20?years post injury). CONCLUSION:The number of publications in the era before the ACRM call for action and afterwards were almost identical. In order to tailor interventions for the appropriate groups of TBI patients, more neurosexuality research is needed to increase awareness of the importance of sexuality as a health outcome for individuals with neurodisabilities.

Project description:All work was performed at the Barrow Neurological Institute at Phoenix Children's Hospital. Objective: Investigate injury severity, neuroimaging, physiology, and outcomes with bolus hyperosmolar therapy (HT) of 3% hypertonic saline or mannitol. Methods: Retrospective cohort analysis was performed. Physiologic variables included intracranial pressure (ICP), arterial blood pressure (ABP), and heart rate (HR). Volume-pressure compensation (PVC) indices included ICP pulse amplitude (AMP) and correlation of AMP and ICP (RAP). Cerebrovascular pressure reactivity (CVPR) indices included pressure reactivity index (PRx), pulse amplitude index (PAx), wavelet PRx (wPRx), and correlation of AMP and cerebral perfusion pressure (RAC). Heart rate variability (HRV) indices included heart rate standard deviation (HRsd), heart rate root mean square of successive differences (HRrmssd) and low-high frequency ratio (LHF). Outcome was assessed using Glasgow Outcomes Scale Extended Pediatrics, 12-months post-injury. Generalized estimating equations was applied to investigate associations of physiologic changes and pre-treatment indices with HT efficacy. Repeated measures analysis of variance was applied to investigate changes after HT without intracranial hypertension (ICH). Wilcoxon rank-sum was applied to investigate HT responsiveness with age, injury severity, neuroimaging, and outcomes. Results: Thirty children received bolus HT. ICH reduction after HT was associated with reduced ICP (p = 0.0064), ABP (p = 0.0126), PRx (p = 0.0063), increased HRsd (p = 0.0408), and decreased pretreatment RAC (p = 0.0115) and wPRx (p = 0.0072). HT-responsive patients were older and had improved outcomes (p = 0.0394). HT without ICH was associated with increased ICP (P < 0.0001) and ABP (P < 0.0001), increases in all HRV indices and decreases in all PVC indices. Conclusion: After pediatric TBI, efficacious HT is associated with decreased ICP and ABP, pre-treatment indices suggesting efficient CVPR, and potentially improved outcomes.
