Race, ethnicity, and clinical outcome following sport-related concussion: a systematic review.

Introduction: This systematic review examined whether race or ethnicity are associated with clinical outcomes (e.g., time to return to school/sports, symptom duration, vestibular deficits, and neurocognitive functioning) following sport-related concussion among child, adolescent, or college-aged student athletes.

Constraining the formation and transport of lunar impact glasses using the ages and chemical compositions of Chang'e-5 glass beads.

Impact glasses found in lunar soils provide a possible window into the impact history of the inner solar system. However, their use for precise reconstruction of this history is limited by an incomplete understanding of the physical mechanisms responsible for their origin and distribution and possible relationships to local and regional geology. Here, we report U-Pb isotopic dates and chemical compositions of impact glasses from the Chang'e-5 soil and quantitative models of impact melt formation and ejection that account for the compositions of these glasses.

Longitudinal evaluation of neurologic-post acute sequelae SARS-CoV-2 infection symptoms.

Objective: To assess the initial features and evolution of neurologic Postacute Sequelae of SARS-CoV-2 infection (neuro-PASC) in patients with and without prior neurologic disease.

Methods: Participants with neurologic symptoms following acute SARS-CoV-2 infection were recruited from October 9, 2020 to October 11, 2021. Clinical data included a SARS-CoV-2 infection history, neurologic review of systems, neurologic exam, Montreal cognitive assessment (MoCA), and symptom-based self-reported surveys at baseline (conducted after acute infection) and 6-month follow-up assessments.

Multiple Sclerosis Performance Test (MSPT): Normative study of 428 healthy participants ages 18 to 89.

Background: The Multiple Sclerosis Performance Test (MSPT) is a self-administered, iPad®-based, computerized system for quantifying neuroperformance (cognition, upper and lower extremity motor function, and vision) in patients with multiple sclerosis (MS).

Objective: The goal of the study is to provide regression-based norms for the four MSPT test modules to adjust for the influence of demographic variables (age, education, and sex).

Methods: The MSPT was administered to 428 cognitively intact, healthy adults (ages 18 to 89 years).

Association of Historic Housing Policy, Modern Day Neighborhood Deprivation and Outcomes After Inpatient Hospitalization.

Objective: To evaluate the association of historical racist housing policies and modern-day healthcare outcomes.

Summary Of Background Data: In 1933 the United States Government Home Owners Loan Corporation (HOLC) used racial composition of neighborhoods to determine creditworthiness and labeled them "Best", "Still Desirable", "Definitely Declining", and "Hazardous." Although efforts have been made to reverse these racist policies that structurally disadvantage those living in exposed neighborhoods, the lasting legacy on modern day healthcare outcomes is uncertain.

Age and composition of young basalts on the Moon, measured from samples returned by Chang'e-5.

Orbital data indicate that the youngest volcanic units on the Moon are basalt lavas in Oceanus Procellarum, a region with high levels of the heat-producing elements potassium, thorium, and uranium. The Chang’e-5 mission collected samples of these young lunar basalts and returned them to Earth for laboratory analysis. We measure an age of 1963 ± 57 million years for these lavas and determine their chemical and mineralogical compositions.

Addressing neuropsychological diagnostics in adults with epilepsy: Introducing the International Classification of Cognitive Disorders in Epilepsy: The IC CODE Initiative.

This paper addresses the absence of an international diagnostic taxonomy for cognitive disorders in patients with epilepsy. Initiated through the 2020 Memorandum of Understanding between the International League Against Epilepsy and the International Neuropsychological Society, neuropsychological representatives from both organizations met to address the problem and consequences of the absence of an international diagnostic taxonomy for cognitive disorders in epilepsy, overview potential solutions, and propose specific solutions going forward. The group concluded that a classification of cognitive disorders in epilepsy, including an overall taxonomy and associated operational criteria, was clearly lacking and sorely needed.

Multimodal imaging of language reorganization in patients with left temporal lobe epilepsy.

This study explored the relationships among multimodal imaging, clinical features, and language impairment in patients with left temporal lobe epilepsy (LTLE). Fourteen patients with LTLE and 26 controls underwent structural MRI, functional MRI, diffusion tensor imaging, and neuropsychological language tasks. Laterality indices were calculated for each imaging modality and a principal component (PC) was derived from language measures.

Extensive wet episodes in Late Glacial Australia resulting from high-latitude forcings.

Millennial-scale cooling events termed Heinrich Stadials punctuated Northern Hemisphere climate during the last glacial period. Latitudinal shifts of the intertropical convergence zone (ITCZ) are thought to have rapidly propagated these abrupt climatic signals southward, influencing the evolution of Southern Hemisphere climates and contributing to major reorganisation of the global ocean-atmosphere system. Here, we use neodymium isotopes from a marine sediment core to reconstruct the hydroclimatic evolution of subtropical Australia between 90 to 20 thousand years ago.

Psychiatric Disease Preceding Intracranial Tumor Diagnosis: Investigating the Association.

Objective: Here, we examine rates of intracranial tumor diagnoses in patients with and without comorbid psychiatric diagnoses to better understand how psychiatric disease may alter risk profiles for brain tumor diagnosis.

Methods: We used a longitudinal version of the California Office of Statewide Health Planning and Development (OSHPD) database, which includes all inpatient admissions in California from 1995 to 2010. We examined patients with confirmed hospital admissions from 1997 to 2004.

Improving Social Security's Financial Capability Assessments.

When Social Security beneficiaries are incapable of managing their benefits, the agency can appoint a representative payee to administer benefits on their behalf. A committee of the Institute of Medicine was asked by the Social Security Administration to review the process by which financial capability determinations are made and to recommend improvements. The committee's conclusions and recommendations include the following: giving priority to real-world financial performance in assessing capability, providing clearer instructions to informants, developing systematic approaches to identifying beneficiaries at risk of incapability, exploring the use of a supervised direct payment option, and instituting regular data collection to assist in improving operations.

Syndrome of acute anxiety among marines after recent arrival at high altitude.

Management of mental health is critical for maintenance of readiness in austere military environments. Emerging evidence implicates hypoxia as an environmental trigger of anxiety spectrum symptomatology. One thousand thirty-six unacclimatized infantry Marines ascended from sea level to the Marine Corps Mountain Warfare Training Center (2,061-3,383 m) for a 30-day exercise.

The discovery of kimberlites in Antarctica extends the vast Gondwanan Cretaceous province.

Kimberlites are a volumetrically minor component of the Earth's volcanic record, but are very important as the major commercial source of diamonds and as the deepest samples of the Earth's mantle. They were predominantly emplaced from ≈2,100 Ma to ≈10 ka ago, into ancient, stable regions of continental crust (cratons), but are also known from continental rifts and mobile belts. Kimberlites have been reported from almost all major cratons on all continents except for Antarctica.

Demographically corrected norms for African Americans and Caucasians on the Hopkins Verbal Learning Test-Revised, Brief Visuospatial Memory Test-Revised, Stroop Color and Word Test, and Wisconsin Card Sorting Test 64-Card Version.

Memory and executive functioning are two important components of clinical neuropsychological (NP) practice and research. Multiple demographic factors are known to affect performance differentially on most NP tests, but adequate normative corrections, inclusive of race/ethnicity, are not available for many widely used instruments. This study compared demographic contributions for widely used tests of verbal and visual learning and memory (Brief Visual Memory Test-Revised, Hopkins Verbal Memory Test-Revised) and executive functioning (Stroop Color and Word Test, Wisconsin Card Sorting Test-64) in groups of healthy Caucasians (n = 143) and African Americans (n = 103).

Association between dyads and correct responses on the Paced Auditory Serial Addition Task (PASAT).

The sensitivity of the Paced Auditory Serial Addition Task (PASAT) to working memory deficits may be enhanced by examining "dyads" (i.e., correct responses immediately preceded by a correct response) as a complement to the traditional total correct summary score.

Demographically adjusted normative standards for new indices of performance on the Paced Auditory Serial Addition Task (PASAT).

The Paced Auditory Serial Addition Task (PASAT) is a complex cognitive test sensitive to neuropsychological disorders. Its traditional Total Correct score seemingly reflects multiple cognitive abilities, including attention, working memory, and processing speed. Snyder, Aniskiewicz, and Snyder (1993) modified scoring guidelines for the PASAT to give credit only for "dyads.

Isotopic enhancements of 17O and 18O from solar wind particles in the lunar regolith.

Differences in isotopic abundances between meteorites and rocks on Earth leave unclear the true composition of the gas out of which the Solar System formed. The Sun should have preserved in its outer layers the original composition, and recent work has indicated that the solar wind is enriched in 16O, relative to Earth, Mars and bulk meteorites. This suggests that self-shielding of CO due to photo-dissociation, which is a well understood process in molecular clouds, also led to evolution in the isotopic abundances in the early Solar System.
