The Co-Occurrence of Vestibular/Ocular Motor Provocation and State Anxiety in Adolescents and Young Adults with Concussion.

Vestibular/ocular motor provocation and state anxiety are both independently linked to poor recovery outcomes following concussion. However, the relationship between these two clinical presentations and their co-occurring effects on concussion recovery outcomes is understudied. The purpose was to examine the co-occurring effects of vestibular/ocular motor provocation and state anxiety following concussion.

Preexisting antibody assays for gene therapy: Considerations on patient selection cutoffs and companion diagnostic requirements.

Recombinant adeno-associated virus (AAV) vectors are the leading delivery vehicle used for gene therapies. Anti-AAV antibodies (AAV Abs) can interact with the viral capsid component of an AAV-based gene therapy (GT). Therefore, patients with preexisting AAV Abs (seropositive patients) are often excluded from GT trials to prevent treatment of patients who are unlikely to benefit or may have a higher risk for adverse events outweighing treatment benefits.

Effect of silicone oil versus gas tamponade on macular layer microstructure after pars plana vitrectomy for macula on rhegmatogenous retinal detachment.

Purpose: To analyze structural changes in the macular retinal layers and sub-foveal choroidal thickness (SFCT) in eyes after macula-on rhegmatogenous retinal detachment (RRD) repair by pars plana vitrectomy with either silicone oil (SO) or gas tamponade, and the effect of these changes on visual acuity.

Patients And Methods: Retrospective study which included 26 eyes in the SO Group and 32 in the Gas Group. Optical coherence tomography (OCT) scans of the affected eyes were obtained before surgery, and 3 months after PPV in the Gas Group, and during silicone oil in situ and 3 months after SO removal, in the SO Group.

Neurocognitive Concussion Test Performance for Student Athletes on the Autism Spectrum.

Objective: To examine baseline neurocognitive functioning among adolescent athletes on the autism spectrum based on self-reported level of academic performance.

Method: Participants in this cross-sectional, observational study were 6,441 adolescent athletes with a self-reported diagnosis of autism who completed pre-season neurocognitive testing using Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT); 4,742 reported a co-occurring learning disorder (LD), and 6,612 individuals without autism or LD were included as a control group. The majority (57%) self-reported Average Academic Performance, 39% Above Average, and 4% Below Average performance.

Progesterone Levels in Adolescent Female Athletes May Contribute to Decreased Cognitive Performance During Acute Phase of Sports-Related Concussion.

Although many outcome studies pertaining to sports-related concussion exist, female athletes with concussion remain an understudied group. We examined whether neurocognitive performance in adolescent females with sports-related concussion (SRC) is related to menstrual cycle-related hormone levels measured at one-week post-concussion, one-month post-concussion, or both. Thirty-eight female athletes, ages 14-18, were matched into two groups: SRC or healthy control.

Reliable Change Indices for the Serial Administration of the Concussion Clinical Profiles Screening Tool.

Context: The Concussion Clinical Profiles Screening Tool (CP Screen) self-report concussion symptom inventory is often administered at weekly intervals. However, 1-week reliable change indices (RCIs) for clinical cutoffs and the test-retest reliability of the CP Screen are unknown.

Objective: To document RCI cutoff scores and 1-week test-retest reliability for each profile and modifier of the CP Screen for men and women.

The prevalence and correlates of scores falling below ImPACT embedded validity indicators among adolescent student athletes.

Valid performance on preseason baseline neurocognitive testing is essential for accurate comparison between preseason and post-concussion test results. Immediate Post-Concussion and Cognitive Testing (ImPACT) is commonly used to measure baseline neurocognitive function in athletes. We examined the prevalence of invalid performance on ImPACT baseline testing and identified correlates of invalid performance.

Information seeking behaviors and attitudes of wives of former football players regarding chronic traumatic encephalopathy.

This study examines CTE-related knowledge and information-seeking behaviors of caregivers of persons who are at high risk of CTE. Online survey responses were collected from 64 females, ages 18-74, who were married to former college, semiprofessional, or professional football players and were fluent in English. Ranging from 0 to 18, a score was calculated to represent level of CTE knowledge.

Unilateral Retinitis Pigmentosa Associated with Possible Ciliopathy and a Novel Mutation.

Unilateral retinitis pigmentosa (URP) is a rare retinal dystrophy. We describe the clinical course of two patients with (URP) unilateral retinitis pigmentosa confirmed by genetic testing, indicating ciliary dysfunction. Methods: The methods used in this study included a detailed ophthalmic examination, multimodal retinal imaging, Goldmann visual fields, full-field electroretinography (ffERG) and targeted next-generation sequencing.

Electrophysiological Evaluation of Fleck Retina and Temporal Macular Thinning in X-Linked Alport's Syndrome.

We report a 39-year-old with Alport's syndrome. The patient presented with anterior lenticonus, cataract, and a corrected distance visual acuity of 20/25 and 20/60 in the right and left eyes, respectively. Fundus examination revealed generalized retinal flecks sparing the fovea in both eyes.

The Frequency of Low Scores on ImPACT in Adolescent Student-Athletes: Stratification by Race and Socioeconomic Status Using Multivariate Base Rates.

This study examined the associations between the frequency of low scores on the Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) by race and socioeconomic status (SES), using the proxy of Title I school status, among adolescent student-athletes and calculated multivariate base rates. There were 753 participants assigned to groups based on race (White: = 430, 59.8%; Black: = 289, 40.

A Cross-Cultural Examination of Parental Knowledge of Concussion in Three Countries.

The aim of the present study was to examine and compare knowledge regarding concussion among parents of youth soccer players, ages 5-17, from the United States, Israel, and Sicily. Results revealed parents from the United States were more knowledgeable than Israeli and Sicilian parents and were more likely to have a previous history of concussion in their children, themselves, and their social contacts. The success of concussion education, programming, and legislation in the US may account for the greater knowledge of US parents and is reason to advocate for similar resources for youth athletes internationally.

Comparison of Posterior Hyaloid Assessment Using Preoperative Optical Coherence Tomography and Intraoperative Triamcinolone Acetonide Staining During Vitrectomy.

Purpose: To compare the specificity of diagnosing posterior vitreous detachment (PVD) using preoperative optical coherence tomography (OCT) versus intraoperative triamcinolone acetonide (TA) staining in patients undergoing vitrectomy.

The purpose of the study is to report a case of peripheral exudative hemorrhagic chorioretinopathy (PEHCR), managed surgically with favorable visual outcome. A 66-year-old female presented with painless visual loss due to dense vitreous and subretinal hemorrhage extending from the far periphery to the macula. Pars plana vitrectomy (PPV) with subretinal tissue plasminogen activator (TPA) injection was performed resulting in good anatomical and visual outcome.

A Population-Based Study of Pre-Existing Health Conditions in Traumatic Brain Injury.

Health factors impacting both the occurrence of, and recovery from traumatic brain injury (TBI) vary in complexity, and present genuine challenges to researchers and healthcare professionals seeking to characterize injury consequences and determine prognosis. However, attempts to clarify causal links between injury characteristics and clinical outcomes (including mortality) often compel researchers to exclude pre-existing health conditions (PECs) in their samples, including psychiatric history, medication usage, and other comorbid conditions. In this pre-registered population-based study (total starting  = 939,123 patients), we examined trends in PEC incidence over 22 years in the state of Pennsylvania (1997-2019) in individuals sustaining TBI ( = 169,452) and individuals with orthopedic injury ( = 87,637).
