Cognitive reserve is associated with education, social determinants, and cognitive outcomes among older American Indians in the Strong Heart Study.

Cognitive reserve, a component of resilience, may be conceptualized as the ability to overcome accumulating neuropathology and maintain healthy aging and function. However, research measuring and evaluating it in American Indians is needed. We recruited American Indians from 3 regional centers for longitudinal examinations (2010-13, n = 818; 2017-19, n = 403) including MRI, cognitive, clinical, and questionnaire data.

Epidemiology of Head Injury and Associations with Clinical and Neuropsychological Test Scores in Older American Indians: Data from the Strong Heart Study.

Background: American Indians have the highest mortality and hospitalizations from head injury of all US groups; however, little is known about prevalence, risk, or outcomes in this population.

Methods: The Strong Heart Study recruited American Indians representing 11 tribes and communities across three regions for two sequential examinations in 2010-2019. Participants were asked to self-report prior head injury, loss of consciousness (LOC), cause, sociodemographics, and behaviors (age, sex, education, bilingual, smoking, alcohol use, stroke).

Psychometric Reliability, Validity, and Generalizability of MoCA in American Indian Adults: The Strong Heart Study.

Standardized neuropsychological instruments are used to evaluate cognitive impairment, but few have been psychometrically evaluated in American Indians. We collected Montreal Cognitive Assessment (MoCA) in 403 American Indians 70 to 95 years, as well as age, sex, education, bilingual status, depression symptoms, and other neuropsychological instruments. We evaluated inferences of psychometric validity, including scoring inference using confirmatory factor analysis and structural equation modeling, generalizability inference using reliability coefficient, and extrapolation inference by examining performance across different contexts and substrata.

Algorithm-defined memory impairment in older American Indians: The Strong Heart Study.

Objective: Assessment of cognition in American Indians poses challenges, including barriers to healthcare, unvalidated clinical standards, and confounding social determinants of health. Alternative strategies for case identification include algorithmic methods, which can outperform clinical judgment in some circumstances.

Method: Algorithmic methods can be maximized using single-domain tests with multiple-serial trial tasks, such as the California Verbal Learning Test II-Short Form (CVLT-SF).

The state of cancer-focused community outreach and engagement (COE): reflections of Black COE directors.

The requirement of community outreach and engagement (COE) as a major component of the National Cancer Institute (NCI) Cancer Center Support Grant has had an enormous impact on the way NCI-designated cancer centers identify, investigate, and address the needs of their catchment area (CA) communities. Given the wide-ranging diversity of our nation, COE's scope of work (SOW) is extremely demanding and complex. Yet, COE is often marginalized and viewed as void of scientific methods when, in fact, it requires specialized scientific knowledge and a broad range of proficiencies.

Epidemiology and prevalence of dementia and Alzheimer's disease in American Indians: Data from the Strong Heart Study.

Introduction: Accurate epidemiologic estimates for dementia are lacking for American Indians, despite substantive social and health disparities.

Methods: The Strong Heart Study, a population-based cohort of 11 American Indian tribes, conducted detailed cognitive testing and examinations over two visits approximately 7 years apart. An expert panel reviewed case materials for consensus adjudication of cognitive status (intact; mild cognitive impairment [MCI]; dementia; other impaired/not MCI) and probable etiology (Alzheimer's disease [AD], vascular bain injury [VBI], traumatic brain injury [TBI], other).

Engaging communities to inform the development of a diverse cohort of cancer survivors: formative research for the eat move sleep study (EMOVES).

Psychometric Properties of Controlled Oral Word Association (COWA) Test and Associations With Education and Bilingualism in American Indian Adults: The Strong Heart Study.

The Controlled Oral Word Association (COWA) test is used to assess phonemic fluency and executive function. Formal validation of test scores is important for accurate cognitive evaluation. However, there is a dearth of psychometric validation among American Indian adults.

Electrosprayed Mesenchymal Stromal Cell Extracellular Matrix Nanoparticles Accelerate Cellular Wound Healing and Reduce Gram-Negative Bacterial Growth.

Treatments for acute respiratory distress syndrome are still unavailable, and the prevalence of the disease has only increased due to the COVID-19 pandemic. Mechanical ventilation regimens are still utilized to support declining lung function but also contribute to lung damage and increase the risk for bacterial infection. The anti-inflammatory and pro-regenerative abilities of mesenchymal stromal cells (MSCs) have shown to be a promising therapy for ARDS.

Exploring the complexity and spectrum of racial/ethnic disparities in colon cancer management.

Background: Colorectal cancer is a leading cause of morbidity and mortality across U.S. racial/ethnic groups.

Trust in and Use of COVID-19 Information Sources Differs by Health Literacy among College Students.

People's health information-seeking behaviors differ by their health literacy levels. This study assessed the relationship between health literacy and college students' levels of trust in and use of a range of health information sources of COVID-19. We collected data from August to December 2020 among college students ( = 763) through an online survey.

Effects of feast-famine nutrient regimes on wastewater algal biofuel communities.

Microalgae accumulate lipids in response to nutrient deprivation, and these lipids are a biodiesel fuel stock. Algal cultivation with secondary wastewater effluent is one proposed platform for biofuel production, which provides nutrients to algae while further polishing wastewater effluent. Algal bioreactors were tested using a feast-famine feeding regiment in simulated secondary wastewater effluent to evaluate the effects on lipid content and algal community structure.

Educational and Clinical Associations With Longitudinal Cognitive Function and Brain Imaging in American Indians: The Strong Heart Study.

Background And Objectives: Little is known about incidence of vascular and Alzheimer dementias in American Indians.

Methods: We conducted a large, heterogeneous, population-based, longitudinal cohort study of brain aging in community-dwelling American Indians aged 64-95 years from 11 tribes across 3 states, with neurologic examinations, 1.5T MRI, and extensive cognitive testing.

Racial Disparities in Pulse Oximeter Device Inaccuracy and Estimated Clinical Impact on COVID-19 Treatment Course.

Arterial blood oxygen saturation as measured by pulse oximetry (peripheral oxygen saturation (SpO2)) may be differentially less accurate for people with darker skin pigmentation, which could potentially affect the course of coronavirus disease 2019 (COVID-19) treatment. We analyzed pulse oximeter accuracy and its association with COVID-19 treatment outcomes using electronic health record data from Sutter Health, a large, mixed-payer, integrated health-care delivery system in Northern California. We analyzed 2 cohorts: 1) 43,753 non-Hispanic White (NHW) or non-Hispanic Black/African-American (NHB) adults with concurrent arterial blood gas oxygen saturation/SpO2 measurements taken between January 2020 and February 2021; and 2) 8,735 adults who went to a hospital emergency department with COVID-19 between July 2020 and February 2021.

Implementation of a Multisite Financial Reimbursement Program in Cancer Clinical Trials Integrated With Patient Navigation: A Pilot Randomized Clinical Trial.

Purpose: Cancer clinical trial participants face considerable indirect costs associated with participation, such as travel and lodging, which may contribute to poor enrollment. Here, we report the findings in IMproving Patient Access to Cancer clinical Trials, a pilot feasibility study investigating the efficacy of offering a financial reimbursement program (FRP) during a therapeutic clinical trial discussion with or without additional outreach in improving patient enrollment.

Methods: Study participants for this study were recruited at two National Cancer Institute-designated comprehensive cancer centers (CCCs) from April 8, 2019, to September 19, 2019.

UW Project ECHO-Dementia: Implementation of a virtual clinic and telementoring program to improve dementia diagnosis and treatment in rural and under-resourced primary care settings.

Background: Primary care providers are on the front lines of dementia care and frequently the first point of contact for individuals and families concerned about changes in memory and thinking. In addition to the challenges of managing complex medical comorbidities, primary care providers in rural or lower-resource settings often lack access to specialists, interdisciplinary teams or other programs and services to aid in diagnosis and care of individuals with mild cognitive impairment and dementia. The current project extends an existing technology-based hub and spoke model virtual clinic, Project ECHO (Extension for Community Healthcare Outcomes, University of New Mexico), to improve diagnosis and care of dementia in primary care.

COVID-19 Related Experiences Among College Students With and Without Disabilities: Psychosocial Impacts, Supports, and Virtual Learning Environments.

Alzheimer's Disease Diagnostics Must Be Globally Accessible.

Dementia and Alzheimer's disease (AD) are global health crises, with most affected individuals living in low- or middle-income countries. While research into diagnostics and therapeutics remains focused exclusively on high-income populations, recent technological breakthroughs suggest that low-cost AD diagnostics may soon be possible. However, as this disease shifts onto those with the least financial and structural ability to shoulder its burden, it is incumbent on high-income countries to develop accessible AD healthcare.

Rural College Students' Amenability Toward Using At-Home Human Immunodeficiency Virus and Sexually Transmitted Infection Testing Kits.

Background: College students residing in rural areas of the United States have limited access to human immunodeficiency virus (HIV) and sexually transmitted infection (STI) screening programs; yet, have increased rates of infection.

Methods: Students (N = 326), attending a state university located within a rural community, completed an online survey containing open-ended questions that gauged their perceptions and experiences with HIV/STI testing, amenability to at-home testing technology, and preferences for obtaining at-home testing kits. Inductive coding was used to create themes for each open-ended question.

Loneliness and symptom burden in oncology patients during the COVID-19 pandemic.

Background: Loneliness and social isolation are significant public health problems that are being exacerbated during the coronavirus disease 2019 pandemic. Little is known about the associations between loneliness and symptom burden in oncology patients before and during the pandemic. Study purposes include determining the prevalence of loneliness in a sample of oncology patients; evaluating for differences in demographic, clinical, and symptom characteristics between lonely and nonlonely patients; and determining which demographic, clinical, and symptom characteristics were associated with membership in the lonely group.

Stress and Symptom Burden in Oncology Patients During the COVID-19 Pandemic.

Context: No information is available on oncology patients' level of stress and symptom burden during the coronavirus disease 2019 (COVID-19) pandemic.

Objectives: To evaluate for differences in demographic and clinical characteristics, levels of social isolation and loneliness, and the occurrence and severity of common symptoms between oncology patients with low vs. high levels of COVID-19 and cancer-related stress.

Assessing models of concurrent substance use and sexual consent cues in mainstream films.

College students may not view sexual consent communication while under the influence of substances (i.e., alcohol and drugs) as problematic if media models the co-occurrence of these behaviors.
