RESUMEN
INTRODUCTION: Repeat sport-related concussion (SRC) is anecdotally associated with prolonged recovery. Few studies have examined repeat concussion within the same athlete. We sought to explore differences in symptom burden and recovery outcomes in an individual athlete's initial and repeat SRC. METHODS: A retrospective within-subject cohort study of athletes aged 12-23 years diagnosed with two separate SRCs from 11/2017-10/2020 was conducted. Primary outcomes were initial symptom severity and time-to-symptom-resolution. Secondary outcomes included return-to-learn (RTL) and return-to-play (RTP) duration. RESULTS: Of 868 athletes seen, 47 athletes presented with repeat concussions. Median time between concussions was 244 days (IQR 136-395). Comparing initial to repeat concussion, no differences were observed in time-to-clinic (4.3 ± 7.3vs.3.7 ± 4.6 days, p = 0.56) or initial PCSS (26.2 ± 25.3 vs. 30.5 ± 24.1, p = 0.32). While a difference was observed in time-to-symptom resolution between initial/repeat concussion (21.2 ± 16.3 vs. 41.7 ± 86.0 days, p = 0.30), this did not reach statistical significance. No significant differences were observed in time-to-RTL (17.8 ± 60.6 vs. 6.0 ± 8.3 days, p = 0.26) and RTP (33.2 ± 44.1 vs. 29.4 ± 39.1 days, p = 0.75). Repeat concussion was not associated with symptom resolution on univariate (HR 1.64, 95% CI 0.96-2.78, p = 0.07) and multivariable (HR 0.85, 95% CI 0.49-1.46, p = 0.55) Cox regression. CONCLUSION: No significant differences in symptom duration and RTP/RTL were seen between initial/repeat concussion.

OBJECTIVES: 1) Evaluate the frequency of same-year, repeat concussions; (2) assess predictors of sustaining a repeat concussion; and (3) compare outcomes of athletes with repeat concussions with athletes with single concussion. DESIGN: A retrospective, case-control study. SETTING: Regional sports concussion center. PATIENTS: Adolescents sustaining a sport-related concussions (SRC) from November 2017 to October 2020. INDEPENDENT VARIABLES: Participants were dichotomized into 2 groups: (1) athletes with a single concussion; and (2) athletes with repeat concussions. MAIN OUTCOME MEASURES: Between group and within group analyses were completed to look for differences in demographics, personal and family history, concussion history, and recovery metrics between the 2 groups. RESULTS: Of 834 athletes with an SRC, 56 (6.7%) sustained a repeat concussion and 778 (93.3%) had a single concussion. Between group: Personal history of migraines (19.6% vs 9.5%, χ 2 = 5.795, P = 0.02), family history of migraines (37.5% vs 24.5%, χ 2 = 4.621, P = 0.03), and family history of psychiatric disorders (25% vs 13.1%, χ 2 = 6.224, P = 0.01) were significant predictors of sustaining a repeat concussion. Within group: Among those with a repeat concussion, initial symptom severity was greater (Z = -2.422; P = 0.02) during the repeat concussion and amnesia was more common (χ 2 = 4.775, P = 0.03) after the initial concussion. CONCLUSIONS: In a single-center study of 834 athletes, 6.7% suffered a same-year, repeat concussion. Risk factors included personal/family migraine history and family psychiatric history. For athletes with repeat concussions, initial symptom score was higher after the second concussion, yet amnesia was more common after the initial concussion.

OBJECTIVE: To identify risk factors and generate hypotheses for pediatric persistent postconcussion symptoms (PPCS). SETTING: A regional healthcare system in the Southeastern United States. PARTICIPANTS: An electronic health record-based algorithm was developed and validated to identify PPCS cases and controls from an institutional database of more than 2.8 million patients. PPCS cases (n = 274) were patients aged 5 to 18 years with PPCS-related diagnostic codes or with PPCS key words identified by natural language processing of clinical notes. Age, sex, and year of index event-matched controls (n = 1096) were patients with mild traumatic brain injury codes only. Patients with moderate or severe traumatic brain injury were excluded. All patients used our healthcare system at least 3 times 180 days before their injury. DESIGN: Case-control study. MAIN MEASURES: The outcome was algorithmic classification of PPCS. Exposures were all preinjury medical diagnoses assigned at least 180 days before the injury. RESULTS: Cases and controls both had a mean of more than 9 years of healthcare system use preinjury. Of 221 preinjury medical diagnoses, headache disorder was associated with PPCS after accounting for multiple testing (odds ratio [OR] = 2.9; 95% confidence interval [CI]: 1.6-5.0; P = 2.1e-4). Six diagnoses were associated with PPCS at a suggestive threshold for statistical significance (false discovery rate P < .10): gastritis/duodenitis (OR = 2.8; 95% CI: 1.6-5.1; P = 5.0e-4), sleep disorders (OR = 2.3; 95% CI: 1.4-3.7; P = 7.4e-4), abdominal pain (OR = 1.6; 95% CI: 1.2-2.2; P = 9.2e-4), chronic sinusitis (OR = 2.8; 95% CI: 1.5-5.2; P = 1.3e-3), congenital anomalies of the skin (OR = 2.9; 95% CI: 1.5-5.5; P = 1.9e-3), and chronic pharyngitis/nasopharyngitis (OR = 2.4; 95% CI: 1.4-4.3; P = 2.5e-3). CONCLUSIONS: These results support the strong association of preinjury headache disorders with PPCS. An association of PPCS with prior gastritis/duodenitis, sinusitis, and pharyngitis/nasopharyngitis suggests a role for chronic inflammation in PPCS pathophysiology and risk, although results could equally be attributable to a higher likelihood of somatization among PPCS cases. Identified risk factors should be investigated further and potentially considered during the management of pediatric mild traumatic brain injury cases.

BACKGROUND: Following aneurysmal subarachnoid hemorrhage (SAH), patients are monitored closely for vasospasm in the intensive care unit. Conditional vasospasm-free survival describes the risk of future vasospasm as a function of time elapsed without vasospasm. Conditional survival has not been applied to this clinical scenario but could improve patient counseling and intensive care unit use. The objective of this study was to characterize conditional vasospasm-free survival following SAH. METHODS: This was a single institution, retrospective cohort study of patients treated for aneurysmal SAH between 1/1/2000-6/1/2020. The primary outcome was the development of vasospasm defined by the first instance of either radiographic vasospasm on computed tomography angiography, Lindegaard Index > 3.0 by transcranial doppler ultrasonography, or vasospasm-specific intraarterial therapy. Multivariable Cox regression was performed, and conditional vasospasm-free survival curves were constructed. RESULTS: A total of 528 patients were treated for aneurysmal SAH and 309 (58.5%) developed vasospasm. Conditional survival curves suggest patients who survive to postbleed day 10 without vasospasm have a nearly 90% chance of being discharged without vasospasm. The median onset of vasospasm was postbleed day 6. Age more than 50 years was associated with a lower risk (hazard ratio [HR] = .76; 95% confidence interval [CI] 0.64-0.91; p < 0.001). Higher initial systolic blood pressure (HR = 1.18; 95% CI 1.046-1.350; p = .008), Hunt-Hess grades 4 or 5 (HR = 1.304; 95% CI 1.014-1.676), and modified Fisher scale score of 4 (HR = 1.808; 95% CI 1.198-2.728) were associated with higher vasospasm than the respective lower grades. CONCLUSION: Conditional survival provides a useful framework for counseling patients and making decisions around vasospasm risk for patients with aneurysmal SAH, while risk factor-stratified plots facilitate a patient-centric, evidence-based approach to these conversations and decisions.

OBJECTIVE: To evaluate the variables associated with additional concussion clinic visits before discharge to athletic trainer (AT). DESIGN: Retrospective cohort study. SETTING: Multidisciplinary Sports Concussion Center. PATIENTS: Patients ages 12 to 23 years presenting with a sport-related concussion between January 11, 2017, and January 10, 2020, and were discharged to an AT. METHODOLOGY: Our main outcome variable was being discharged to AT after the initial clinic visit versus those who attended additional clinic visits before AT discharge. We examined the influence of age, sex, initial visit symptom score, family and personal history of psychiatric disorders and migraines, history of prior concussions, and other variables on this outcome. RESULTS: Of 524 patients, 236 were discharged to AT after the initial clinic visit, while 288 patients required additional clinic visits. The additional visit group had higher initial visit symptom scores ( P = 0.002), head imaging performed more frequently ( P < 0.02), a family history of psychiatric disorders and/or migraines ( P < 0.001, P < 0.001), more often reported a prior concussion ( P = 0.02), and was younger ( P = 0.014) compared with the one visit group. In a multiple variable model, the family history of psychiatric disorders [odds ratio (OR), 3.12 (95% CI, 1.531-6.343), P = 0.002], prior concussions [OR, 1.39 (95% CI, 1.020-1.892), P = 0.037], greater initial symptom score [OR, 1.05 (95% CI, 1.031-1.058), P < 0.001], and younger age [OR, 0.87 (95% CI, 0.773-0.979), P = 0.021] were strongly associated with additional visits. CONCLUSIONS: Among athletes treated at a regional sports concussion center, family history of psychiatric disorders, increased symptom score at initial visit, prior concussions, and younger age were each uniquely associated with needing additional clinic visits at the time of initial assessment. Understanding these variables may guide treatment protocols for optimal care.

Primary brain tumors diagnosed during infancy present several challenges for the pediatric neurosurgeon including the management of tumor-related hydrocephalus. Infant tumor-related hydrocephalus (iTRH) is present in over 70% of new diagnoses overall and in over 90% of infants with infratentorial neoplasms. iTRH may be related to direct obstruction of cerebrospinal fluid (CSF) pathways, shedding of protein and/or cells leading to dysfunctional subarachnoid, tumor-related CSF production, or, most frequently, a combination of these mechanisms. Treatment plans must consider the acuity of presentation, the mechanism of iTRH, and the additional neoadjuvant or adjuvant therapies required to treat the neoplasm. This narrative review provides a broad reference on the epidemiology, pathophysiology, and treatment of iTRH.

OBJECTIVE: Craniosynostosis (CS) affects about 1 in 2500 infants and is predominantly treated by surgical intervention in infancy. Later in childhood, many of these children wish to participate in sports. However, the safety of participation is largely anecdotal and based on surgeon experience. The objective of this survey study was to describe sport participation and sport-related head injury in CS patients. METHODS: A 16-question survey related to child/parent demographics, CS surgery history, sport history, and sport-induced head injury history was made available to patients/parents in the United States through a series of synostosis organization listservs, as well as synostosis-focused Facebook groups, between October 2019 and June 2020. Sports were categorized based on the American Academy of Pediatrics groupings. Pearson's chi-square test, Fisher's exact test, and the independent-samples t-test were used in the analysis. RESULTS: Overall, 187 CS patients were described as 63% male, 89% White, and 88% non-Hispanic, and 89% underwent surgery at 1 year or younger. The majority (74%) had participated in sports starting at an average age of 5 years (SD 2.2). Of those participating in sports, contact/collision sport participation was most common (77%), and 71% participated in multiple sports. Those that played sports were less frequently Hispanic (2.2% vs 22.9%, p < 0.001) and more frequently had undergone a second surgery (44% vs 25%, p = 0.021). Only 9 of 139 (6.5%) sport-participating CS patients suffered head injuries; 6 (67%) were concussions and the remaining 3 were nondescript but did not mention any surgical needs. CONCLUSIONS: In this nationwide survey of postsurgical CS patients and parents, sport participation was exceedingly common, with contact sports being the most common sport category. Few head injuries (mostly concussions) were reported as related to sport participation. Although this is a selective sample of CS patients, the initial data suggest that sport participation, even in contact sports, and typically beginning a few years after CS correction, is safe and commonplace.

Objective: To determine chronic traumatic encephalopathy (CTE)-related publication characteristics associated with higher Altmetric scores.Methods: A systematic review of the CTE literature was conducted using PubMed. Publications were coded for: journal impact factor (JIF); publication type (primary versus non-primary data collection); discussion of American football; contact sport-CTE association conclusion (yes versus no/neutral); and Altmetric score. Multivariable ordinal logistic regression identified predictors of higher Altmetric scores.Results: Most of the 270 CTE-related publications did not include primary data collection (60%). The median Altmetric score was 12 (range = 0-3745). Higher Altmetric scores were associated with primary data collection [Odds ratio (OR)Adjusted = 2.29; 95% confidence interval (CI) = 1.35-3.89] and discussing American football (ORAdjusted = 2.11; 95%CI = 1.24-3.59). Among publications concluding contact sport-CTE associations, higher Altmetric scores were associated with higher JIF (3-point-JIF-increase ORAdjusted = 2.11; 95%CI = 1.24-3.59); however, the association of higher Altmetric scores with higher JIF was not found among neutral publications or those concluding no contact sport-CTE associations (3-point-JIF-increase ORAdjusted = 1.07; 95%CI = 0.94-1.22).Conclusions: Most CTE-related publications (60%) did not involve primary data collection. Publication characteristics such as higher JIF and concluding contact sport-CTE associations were associated with higher Altmetric scores. It is important for the academic community to consider strategies to counter publication and promotion bias in the presentation of CTE literature.

OBJECTIVES: To describe historic baseline session administration practices, to assess the utility of a practice trial (an acclimation trial) before the official balance session, and to examine the within-session reliability of the Sway Balance Mobile Application (SBMA). DESIGN: Retrospective observational study. SETTING: Middle schools, high schools, and colleges across the United States. PARTICIPANTS: More than 17 000 student-athletes were included in the Sway Medical database with 7968 individuals meeting this study's inclusion criteria. INDEPENDENT VARIABLES: The Sway Medical database included the following subject characteristics for each student-athlete: age, sex, weight, and height. MAIN OUTCOME MEASURES: Balance assessment score generated by the SBMA. RESULTS: Variable administration practices with significant differences between baseline session averages across methods were found. Individuals who performed an acclimation trial had a significantly higher baseline session average than those who did not. Within-session reliability estimates were in the low to adequate range (r = 0.53-0.78), with higher estimates found for 2 consecutive baseline tests (r = 0.75-0.78). CONCLUSIONS: For maximum clinical utility, a standardized protocol for postural control baseline acquisition is necessary. Acclimation trial should be administered before a baseline session to minimize variability, especially with only 1 to 2 baseline tests. The highest reliability was observed across 2 consecutive baseline tests within the same baseline session. We suggest obtaining baseline balance measurements with an acclimation trial followed by a baseline session with 2 baseline tests. Prospective studies are required for validation.

A positive relationship between sport-related concussion (SRC) history and depressive symptoms in retired National Football League (NFL) athletes has been observed, with self-rated physical functioning identified as a confounding factor. The authors examined the influence of somatic symptom endorsement on the relationship between SRC history and self-reported depressive symptom severity in retired NFL athletes. Forty-three former NFL athletes completed self-report inventories of depression (with the Beck Depression Inventory II) and somatic symptoms (with the adjusted Patient Health Questionnaire-15). A moderation analysis examined the influence of somatic symptoms on the relationship between SRC history and depressive symptom severity. SRC history and somatic symptoms accounted for a significant amount of depressive symptomology. SRC history was not significantly associated with depressive symptom severity at low levels of somatic symptoms but was significant at the mean and high levels. The effect of somatic symptoms on depressive symptoms was nearly twice that of SRC history. The relationship between SRC and depression is complex, and treatment of depression in retired athletes should address comorbid somatic symptoms.

OBJECTIVES: This study investigated the relationship between on-field, objective signs immediately following sport-related concussion and self-reported symptom endorsement within 1 day post injury. METHODS: A retrospective case series of 237 concussed high school athletes was performed. On-field signs were evaluated immediately post injury. Self-reported symptoms (2 clusters) were collected within 1 day post injury. A two-step structural equation model and follow-up bivariate regression analyses of significant on-field signs and symptom clusters were performed. RESULTS: Signs of immediate memory, ß=0.20, p=.04, and postural instability, ß=0.19, p < .01, significantly predicted a greater likelihood of endorsing the cognitive-migraine-fatigue symptom cluster within 1 day post injury. Regarding signs correlated with specific symptoms, immediate memory was associated with symptoms of trouble remembering, χ 2 =37.92, p < .001, odds ratio (OR)=3.89 (95% confidence interval (CI) [2.47, 6.13]), and concentration difficulties, χ 2 =10.84, p=.001, OR=2.13 (95% CI [1.37, 3.30]). Postural instability was associated with symptom endorsement of trouble remembering, χ 2 =12.08, p < .001, OR=1.76 (95% CI [1.29, 2.40]). CONCLUSIONS: Certain post-concussion on-field signs exhibited after injury were associated with specific symptom endorsement within 1 day post injury. Based on these associations, individualized education-based interventions and academic accommodations may help reduce unanticipated worry from parents, students, and teachers following a student-athlete's sport-related concussion, especially in cases of delayed onset symptoms.

PURPOSE OF REVIEW: Sport-related concussion (SRC) and mild traumatic brain injury (mTBI) have been thrust into the national spotlight, with youth athletes bearing the burden of this public health problem. The current review aims to provide a practical summary of pediatric SRC, including key terminology, return to play/school, and risk factors for post-concussion syndrome (PCS). RECENT FINDINGS: While the majority of youth athletes recover within 2 to 4 weeks, approximately 10% of athletes experience a protracted recovery with symptoms lasting months, impacting social, scholastic, and sporting activities. In the pediatric population, the strongest predictors of PCS are initial symptom burden and prior concussion, with mixed results behind the factors of gender, headaches, and learning disability. The role of psychiatric, family history, sports, and socioeconomic factors remain in their infancy.

This study aimed to determine if gameplay performance in the National Football League (NFL) is adversely affected after returning to play from a sport-related concussion (SRC). Players who sustained a SRC between the 2007-2008 and 2013-2014 seasons were identified. Concussed players were matched to nonconcussed control players in a 2:1 (control-case) fashion by position, season, experience, age, body mass index, and time missed. Gameplay statistics were recorded for the three games before and after returning from SRC. When compared with the control group, the majority of NFL players did not demonstrate any performance-based deficits on returning to play after SRC. However, concussed quarterbacks (QBs) displayed a reduced QB rating compared with controls. These results indicate that performance immediately following return from SRC may be adversely affected in certain populations and circumstances, though the overwhelming majority of players showed no decline in performance.

OBJECTIVE Sport-related concussion (SRC) has emerged as a public health problem, especially among student-athletes. Whereas most concussions resolve by 2 weeks, a minority of patients experience postconcussion syndrome (PCS), in which symptoms persist for months. The objective of this study was to elucidate factors predictive of PCS among a sample of National Collegiate Athletic Association (NCAA) student-athletes in the academic years 2009-2010 to 2014-2015. METHODS The SRC data originated from the NCAA Injury Surveillance Program (ISP) in the 2009-2010 to 2014-2015 academic seasons. The NCAA ISP is a prospective database made up of a convenience sample of schools across all divisions. All SRCs are reported by certified athletic trainers. The PCS group consisted of concussed student-athletes with concussion-related symptoms that lasted ≥ 4 weeks. The non-PCS group consisted of concussed student-athletes with symptom resolution in ≤ 2 weeks. Those with symptoms that resolved in the intermediate area of 2-4 weeks were excluded. Odds ratios (ORs) were estimated using logistic regression. RESULTS During the 2009-2010 to 2014-2015 seasons, 1507 NCAA student-athletes sustained an SRC, 112 (7.4%) of whom developed PCS (i.e., concussion-related symptoms that lasted ≥ 4 weeks). Men's ice hockey contributed the largest proportion of concussions to the PCS group (28.6%), whereas men's football contributed the largest proportion of concussions in the non-PCS group (38.6%). In multivariate analysis, recurrent concussion was associated with increased odds of PCS (OR 2.08, 95% CI 1.28-3.36). Concussion symptoms that were also associated with increased odds of PCS included retrograde amnesia (OR 2.75, 95% CI 1.34-5.64), difficulty concentrating (OR 2.35, 95% CI 1.23-4.50), sensitivity to light (OR 1.97, 95% CI 1.09-3.57), and insomnia (OR 2.19, 95% CI 1.30-3.68). Contact level, sex, and loss of consciousness were not associated with PCS. CONCLUSIONS Postconcussion syndrome represents one of the most impactful sequelae of SRC. In this study of exclusively collegiate student-athletes, the authors found that recurrent concussions and various concussion-related symptoms were associated with PCS. The identification of initial risk factors for the development of PCS may assist sports medicine clinicians in providing timely interventions and treatments to prevent morbidity and shorten recovery time after SRC.

OBJECTIVE Over the last 2 decades, sport-related concussion (SRC) has garnered significant attention. Even with increased awareness and athlete education, sideline recognition and real-time diagnosis remain crucial. The need for an objective and standardized assessment of concussion led to the eventual development of the Sport Concussion Assessment Tool (SCAT) during the Second International Conference on Concussion in Sport in 2004, which is now in its third iteration (SCAT3). In an effort to update our understanding of the most well-known sideline concussion assessment, the authors conducted a systematic review of the SCAT and the evidence supporting its use to date. METHODS English-language titles and abstracts published between 1995 and October 2015 were searched systematically across 4 electronic databases and a review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines adapted for the review of a heterogeneous collection of study designs. Peer-reviewed journal articles were included if they reported quantitative data on any iteration of the SCAT, Standardized Assessment of Concussion (SAC), or modified Balance Error Scoring System (mBESS) data at baseline or following concussion in an exclusively athlete population with any portion older than 13 years of age. Studies that included nonathletes, only children less than 13 years old, exclusively BESS data, exclusively symptom scale data, or a non-SCAT-related assessment were excluded. RESULTS The database search process yielded 549 abstracts, and 105 full-text articles were reviewed with 36 meeting criteria for inclusion. Nineteen studies were associated with the SAC, 1 was associated with the mBESS exclusively, and 16 studies were associated with a full iteration of the SCAT. The majority of these studies (56%) were prospective cohort studies. Male football players were the most common athletes studied. An analysis of the studies focused on baseline differences associated with age, sex, concussion history, and the ability to detect an SRC. CONCLUSIONS Looking toward the upcoming Concussion in Sport Group meeting in fall 2016, one may expect further revision to the SCAT3. However, based on this systematic review, the authors propose further, in-depth study of an already comprehensive concussion test, with acute, diagnostic, as well as long-term use.

OBJECTIVE Arachnoid cysts (ACs) are congenital lesions bordered by an arachnoid membrane. Researchers have postulated that individuals with an AC demonstrate a higher rate of structural brain injury after trauma. Given the potential neurological consequences of a structural brain injury requiring neurosurgical intervention, the authors sought to perform a systematic review of sport-related structural-brain injury associated with ACs with a corresponding quantitative analysis. METHODS Titles and abstracts were searched systematically across the following databases: PubMed, Embase, CINAHL, and PsycINFO. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Peer-reviewed case reports, case series, or observational studies that reported a structural brain injury due to a sport or recreational activity (hereafter referred to as sport-related) with an associated AC were included. Patients were excluded if they did not have an AC, suffered a concussion without structural brain injury, or sustained the injury during a non-sport-related activity (e.g., fall, motor vehicle collision). Descriptive statistical analysis and time to presentation data were summarized. Univariate logistic regression models to assess predictors of neurological deficit, open craniotomy, and cystoperitoneal shunt were completed. RESULTS After an initial search of 994 original articles, 52 studies were found that reported 65 cases of sport-related structural brain injury associated with an AC. The median age at presentation was 16 years (range 4-75 years). Headache was the most common presenting symptom (98%), followed by nausea and vomiting in 49%. Thirteen patients (21%) presented with a neurological deficit, most commonly hemiparesis. Open craniotomy was the most common form of treatment (49%). Bur holes and cyst fenestration were performed in 29 (45%) and 31 (48%) patients, respectively. Seven patients (11%) received a cystoperitoneal shunt. Four cases reported medical management only without any surgical intervention. No significant predictors were found for neurological deficit or open craniotomy. In the univariate model predicting the need for a cystoperitoneal shunt, the odds of receiving a shunt decreased as age increased (p = 0.004, OR 0.62 [95% CI 0.45-0.86]) and with male sex (p = 0.036, OR 0.15 [95% CI 0.03-0.88]). CONCLUSIONS This systematic review yielded 65 cases of sport-related structural brain injury associated with ACs. The majority of patients presented with chronic symptoms, and recovery was reported generally to be good. Although the review is subject to publication bias, the authors do not find at present that there is contraindication for patients with an AC to participate in sports, although parents and children should be counseled appropriately. Further studies are necessary to better evaluate AC characteristics that could pose a higher risk of adverse events after trauma.

OBJECTIVE: Most studies regarding sport-related concussion (SRC) focus on high school and collegiate athletes; however, little has been published on children younger than 12 years of age. In a cohort of children aged 8-12 years with SRC, the authors sought to describe demographics, initial presentation, and recovery in this understudied population. METHODS: A retrospective cohort study of children aged 8-12 years who sustained an SRC between November 2017 and April 2022 and were treated at a regional sports concussion center was conducted. Demographic information, injury characteristics, traditional Sport Concussion Assessment Tool 5 (SCAT5) and Child/Parent SCAT5 scores, and outcomes, defined as days to return to learn (RTL), symptom resolution, and return to play (RTP), were reported. Outcomes in boys and girls were compared using effect size analyses given sample size constraints. RESULTS: Forty-seven athletes were included. The mean age was 11.0 ± 0.8 years, and the majority were male (34, 72.3%). A sizable proportion of patients visited an emergency department (19, 40.4%), and many received head imaging (16, 34.0%), mostly via CT (n = 13). The most common sport for boys was football (15, 44.1%), and the most common sports for girls were soccer (4, 30.8%) and cheerleading (4, 30.8%). These athletes reported a variety of symptoms on presentation. It took a mean of 8.8 ± 10.8 days to RTL, 27.3 ± 38.3 days to reach symptom resolution, and 35.4 ± 41.9 days to RTP. When comparing boys versus girls, there appeared to be moderate differences in symptom severity scores (Cohen's d = 0.44 for SCAT5, 0.13 for Child SCAT5, and 0.38 for Parent SCAT5) and minimal differences in recovery (Cohen's d = 0.11 for RTL, n = 35; 0.22 for symptom resolution, n = 22; and 0.12 for RTP, n = 21). CONCLUSIONS: In this cohort of concussed athletes aged 8-12 years, a little less than half of the athletes initially presented to the emergency department, and approximately one-third received acute head imaging. Across all athletes, the mean RTL was slightly more than a week and the mean symptom resolution and RTP were both approximately 1 month; however, much of the cohort is missing recovery outcome measures. This study demonstrated a strong positive correlation between Child SCAT5 and Parent SCAT5 symptom reporting. Future efforts are needed to evaluate differences in clinical presentation and outcomes following SRC between children and older populations.

CONTEXT: People with diabetes mellitus (DM) are at increased risk for adverse health events and complications throughout their lifetime. Whether DM significantly affects collegiate athletes' concussion baseline testing performance remains unclear. OBJECTIVES: To (1) describe the prevalence of DM and associated comorbidities and (2) compare concussion baseline testing performance between student-athletes with DM and student-athletes without DM (NoDM). DESIGN: Retrospective, cross-sectional study. SETTING: University. PATIENTS OR OTHER PARTICIPANTS: Using the Concussion, Assessment, Research and Education (CARE) Consortium research database, we matched athletes with self-reported DM (N = 229) by institution, sex, age, sport, position, testing year, and concussion history to athletes with NoDM (N = 229; total sample mean age = 19.6 ± 1.4 years, women = 42%). MAIN OUTCOME MEASURE(S): Descriptive statistics and χ2 tests of independence with subsequent odds ratios were calculated. Independent-samples t tests compared baseline symptoms, neurocognitive testing, and balance performance between athletes with DM and athletes with NoDM. Effect sizes were determined for significant group differences. RESULTS: At baseline, athletes with DM had higher rates of self-reported pre-existing balance disorders, sleep disorders, seizure disorders, motion sickness, learning disorders, vision and hearing problems, psychiatric disorders, depression, bipolar disorder, nonmigraine headaches, and meningitis than athletes with NoDM (P values < .05). We found balance differences between groups (P = .032, Cohen d = 0.17) such that, on average, athletes with DM had 1 additional error on the Balance Error Scoring System (DM = 13.4 ± 6.5; NoDM = 12.1 ± 5.9). No other comparisons yielded significant results. CONCLUSIONS: Although athletes with DM had high rates of self-reported balance disorders, sleep disorders, seizures, and meningitis, their baseline neurocognitive testing results were largely identical to those of athletes with NoDM. Our findings suggested that nonclinically meaningful differences were present in concussion baseline balance testing but no significant differences were noted in cognitive testing; however, the effect of DM on concussion recovery remains unknown.

Introduction The middle fossa craniotomy (MFCs) is commonly utilized for spontaneous cerebrospinal fluid (CSF) leaks, encephaloceles, and superior semicircular canal dehiscence (SSCD). This study compares postoperative outcomes of MFCs with and without LD use. Methods A retrospective cohort study of adults over the age of 18 years presenting for the repair of nonneoplastic CSF leak, encephalocele, or SSCD via MFC from 2009 to 2021 was conducted. The main exposure of interest was the placement of an LD. The primary outcome was the presence of postoperative complications (acute/delayed neurologic deficit, meningitis, intracranial hemorrhage, and stroke). Secondary outcomes included operating room (OR) time, length of stay, recurrence, and need for reoperation. Results In total, 172 patients were included, 96 of whom received an LD and 76 who did not. Patients not receiving an LD were more likely to receive intraoperative mannitol ( n = 24, 31.6% vs. n = 16, 16.7%, p = 0.02). On univariate logistic regression, LD placement did not influence overall postoperative complications (OR: 0.38, 95% confidence interval [CI]: 0.05-2.02, p = 0.28), CSF leak recurrence (OR: 0.75, 95% CI: 0.25-2.29, p = 0.61), or need for reoperation (OR: 1.47, 95% CI: 0.48-4.96, p = 0.51). While OR time was shorter for patients not receiving LD (349 ± 71 vs. 372 ± 85 minutes), this difference was not statistically significant ( p = 0.07). Conclusion No difference in postoperative outcomes was observed in patients who had an intraoperative LD placed compared to those without LD. Operative times were increased in the LD cohort, but this difference was not statistically significant. Given the similar outcomes, we conclude that LD is not necessary to facilitate safe MCF for nonneoplastic skull base pathologies.
RESUMEN
OBJECTIVE: The aim of this study was to compare clinical and craniometric outcomes of patients treated for hydrocephalus following fetal myelomeningocele repair (fMMR) via a ventriculoperitoneal shunt (VPS) or endoscopic third ventriculostomy with choroid plexus cauterization (ETV/CPC). METHODS: This was a retrospective cohort study of children who were treated for hydrocephalus following fMMR via VPS or ETV with or without CPC (ETV ± CPC) at Vanderbilt between 2012 and 2021. The primary outcomes were treatment failure and time to failure (TTF). Secondary outcomes included changes in hydrocephalus metrics (fronto-occipital horn ratio [FOHR] and head circumference measurements) and healthcare resource utilization (number of hospital admissions, clinic visits, and neuroimaging findings). RESULTS: Among 88 patients who underwent fMMR, 37 (42%) required permanent CSF diversion, of whom 19 received treatment at the authors' institution. Twelve patients underwent ETV ± CPC, and 7 underwent VPS placement at a median corrected age of 23 weeks versus 1 week (p = 0.002). The preoperative median head circumference percentiles and z-scores for patients in the ETV ± CPC cohort were similar to those of the VPS cohort (percentiles: 98.5 vs 94.0, p = 0.064; z-scores: 2.32 vs 1.60, p = 0.111). There was no difference in preoperative median FOHR measurements between the two cohorts (0.57 vs 0.59, p = 0.53). At 6 months postoperatively, the median head circumference percentile and z-score for the ETV ± CPC cohort remained similar between the two cohorts (percentiles: 98.0 vs 67.5, p = 0.315; z-scores: 2.12 vs 0.52, p = 0.307). There was no difference in the change in FOHR (-0.06 vs -0.09, p = 0.37) and change in head circumference percentile (-1.33 vs -28.6, p = 0.058) between the cohorts 6 months after the index CSF diversion procedure. One patient in the ETV ± CPC cohort experienced a seizure and a nonoperative subdural hemorrhage postoperatively; no other complications were observed. Six of the 7 patients in the VPS cohort required shunt revision with a median TTF of 9.8 months while 2 of the 12 ETV ± CPC patients required a repeat ETV at a median of 17.5 months (86% vs 17%, p = 0.013). The median number of hydrocephalus-related hospital readmissions was significantly lower in the ETV ± CPC cohort than in the VPS cohort (0 vs 1, p = 0.006). The ETV ± CPC cohort had fewer CT scans (0 vs 2, p = 0.004) and radiographs (0 vs 2, p < 0.001) than the VPS cohort. CONCLUSIONS: In a single-center cohort, hydrocephalic fMMR patients treated via ETV ± CPC remained shunt free, while a majority of patients receiving an upfront shunt required revision. This is the first study comparing ETV ± CPC with VPS in the fMMR hydrocephalus population. While larger, multicenter studies are needed, these results suggest that ETV/CPC may be a preferred means of CSF diversion following fMMR.
