National Institute on Aging's 50th Anniversary: Advancing Cognitive Aging Research and the Cognitive Health of Older Adults.

In celebration of the National Institute on Aging's (NIA) 50th anniversary, this paper highlights the significant advances in cognitive aging research and the promotion of cognitive health among older adults. Since its inception in 1974, the NIA has played a pivotal role in understanding cognitive aging, including cognitive epidemiology, interventions, and methods, for measuring cognitive change. Key milestones include the shift toward understanding cognitive impairment and Alzheimer's disease and Alzheimer's disease-related dementias (AD/ADRD), the development of large-scale longitudinal studies, and the incorporation of AD/ADRD-related biomarkers in cognitive aging cohorts.

Phenotypic and Genotypic Characterizations of Antimicrobial-Resistant Isolates from Diverse Retail Meat Samples in North Carolina During 2018-2019.

Surveillance of antimicrobial-resistant pathogens in U.S. retail meats is conducted to identify potential risks of foodborne illness.

Characteristics of antimicrobial resistance in Escherichia coli isolated from retail meat products in North Carolina.

Background: Escherichia coli is commonly used as an indicator for antimicrobial resistance (AMR) in food, animal, environment, and human surveillance systems. Our study aimed to characterize AMR in E. coli isolated from retail meat purchased from grocery stores in North Carolina, USA as part of the National Antimicrobial Resistance Monitoring System (NARMS).

Comparing the effectiveness of two theory-based strategies to promote cognitive training adherence.

This study compared the effectiveness of two theory-based strategies to promote cognitive training adherence among older adults ( = 70 years, = 4.42, range = 64-84). Strategies incorporated either (a) elements of implementation intention formation or (b) positive message framing, both of which have been found to promote adherence to health behaviors in other domains.

Family caregiver roles and challenges in assisting patients with cancer treatment decision-making: Analysis of data from a national survey.

Background: We aimed to describe the roles and challenges of family caregivers involved in patients' cancer treatment decision-making.

Methods: Family caregiver-reported data were analyzed from a national survey conducted in the United States by CancerCare® (2/2021-7/2021). Four select-all-that-apply caregiver roles were explored: (1) observer (patient as primary decision-maker); (2) primary decision-maker; (3) shared decision-maker with patient and (4) decision delegated to healthcare team.

Decision support training for advanced cancer family caregivers: Study protocol for the CASCADE factorial trial.

Background: Patients with advanced cancer face numerous decisions when diagnosed and often receive decision support from family caregivers. The CASCADE (CAre Supporters Coached to be Adept DEcision partners) factorial trial intervention aims to train caregivers in skills to provide effective decision support to patients and identify most effective intervention components.

Methods: This is a 2-site, single-blind, 2 factorial trial to test components of the CASCADE decision support training intervention for family caregivers of patients with newly-diagnosed advanced cancer delivered by specially-trained, telehealth, palliative care lay coaches over 24 weeks.

Quinolone-resistant Escherichia coli at the interface between humans, poultry and their shared environment- a potential public health risk.

Background: Commensal Escherichia coli residing in the guts of humans and animals are reservoirs of multidrug resistance (MDR) genes, including quinolone resistance genes, in humans and poultry. This study aimed to characterize quinolones resistance in E. coli recovered from poultry workers, chickens, and poultry farm/market environments in Abuja, Nigeria.

Deep learning-based predictions of older adults' adherence to cognitive training to support training efficacy.

As the population ages, the number of older adults experiencing mild cognitive impairment (MCI), Alzheimer's disease, and other forms of dementia will increase dramatically over the next few decades. Unfortunately, cognitive changes associated with these conditions threaten independence and quality of life. To address this, researchers have developed promising cognitive training interventions to help prevent or reverse cognitive decline and cognitive impairment.

Toward the Adoption of Loop-Mediated Isothermal Amplification for Screening at the National Antimicrobial Resistance Monitoring System's Retail Meat Sites.

The National Antimicrobial Resistance Monitoring System (NARMS) is a One Health program in the United States that collects data on antimicrobial resistance in enteric bacteria from humans, animals, and the environment. is a major pathogen tracked by the NARMS retail meat arm but currently lacks a uniform screening method. We evaluated a loop-mediated isothermal amplification (LAMP) assay for the rapid screening of from 69 NARMS retail meat and poultry samples.

Bias reported by family caregivers in support received when assisting patients with cancer-related decision-making.

Background: Family caregivers play an increasing role in cancer treatment decision-making. We examined bias reported by family caregivers in the support they and their patient received from their healthcare team when making these decisions, including associations with distress.

Methods: Analysis of 2021 national survey data of family caregivers of patients with cancer (N = 2703).

A Machine-Learning Based Approach for Predicting Older Adults' Adherence to Technology-Based Cognitive Training.

Adequate adherence is a necessary condition for success with any intervention, including for computerized cognitive training designed to mitigate age-related cognitive decline. Tailored prompting systems offer promise for promoting adherence and facilitating intervention success. However, developing adherence support systems capable of just-in-time adaptive reminders requires understanding the factors that predict adherence, particularly an imminent adherence lapse.

Multidrug resistance and virulence genes carried by mobile genomic elements in Salmonella enterica isolated from live food animals, processed, and retail meat in North Carolina, 2018-2019.

An estimated 1000,000 domestic salmonellosis cases are attributed to food as a vehicle of exposure. Among Food Safety and Inspection Service (FSIS)-regulated products, approximately 360,000 salmonellosis cases are associated with consumption of meat, poultry, and egg products. Salmonella vaccination programs instituted in U.

The Project ENABLE Cornerstone randomized controlled trial: study protocol for a lay navigator-led, early palliative care coaching intervention for African American and rural-dwelling advanced cancer family caregivers.

Background: Family caregivers play a vital, yet stressful role in managing the healthcare needs and optimizing the quality of life of patients with advanced cancer, from the time they are newly diagnosed until end of life. While early telehealth palliative care has been found to effectively support family caregivers, little work has focused on historically under-resourced populations, particularly African American and rural-dwelling individuals. To address this need, we developed and are currently testing Project ENABLE (Educate, Nurture, Advise, Before Life Ends) Cornerstone, a lay navigator-led, early palliative care coaching intervention for family caregivers of African American and rural-dwelling patients with newly diagnosed advanced cancer.

The Impact of the COVID-19 Pandemic on Business Ownership Across Racial/Ethnic Groups and Gender.

This study examined the economic impact of the COVID-19 pandemic on US older entrepreneurs' businesses using the Health and Retirement Study. We estimated logistic regression models to document the odds of experiencing economic impact. The COVID-19 pandemic has affected nearly 76% of US older entrepreneurs but has disproportionately impacted the businesses of Black, Hispanic, Asian/other races, and women entrepreneurs.

Rural-Urban Differences in Cognition: Findings From the Advanced Cognitive Training for Independent and Vital Elderly Trial.

ObjectivesWe examined associations between three geographic areas (urban, suburban, rural) and cognition (memory, reasoning, processing speed) over a 10-year period. Data were obtained from 2539 participants in the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) trial. Multilevel, mixed-effects linear regression was used to estimate cognitive trajectories by geographical areas over 10 years, after adjusting for social determinants of health.

Cognitive differences across ethnoracial category, socioeconomic status across the Alzheimer's disease spectrum: Can an ability discrepancy score level the playing field?

An ability discrepancy (crystallized minus fluid abilities) might be a personally relevant cognitive marker of risk for Alzheimer's disease (AD) and might help reduce measurement bias often present in traditional measures of cognition. In a large national sample of adults aged 60-104 years (N = 14,257), we investigated whether the intersectionality of group characteristics previously shown to pose a risk for AD including ethnoracial category, socioeconomic status, and sex (a) differed in ability discrepancy compared to traditional neuropsychological tests and (b) moderated the relationship between an ability discrepancy and AD symptom severity. In cognitively normal older adults, results indicated that across each decade, fluid and memory composite scores generally exhibited large group differences with sex, education, and ethnoracial category.

Relative effectiveness of general versus specific cognitive training for aging adults.

In the present study, we examined three experimental cognitive interventions, two targeted at training general cognitive abilities and one targeted at training specific instrumental activities of daily living (IADL) abilities, along with one active control group to compare benefits of these interventions beyond expectation effects, in a group of older adults ( = 230). Those engaged in general training did so with either the web-based brain game suite BrainHQ or the strategy video game Rise of Nations, while those trained on IADL skills completed instructional programs on driving and fraud awareness. Active control participants completed sets of puzzles.

Protecting our Elders and Developing Equitable Policies During Public Health Emergencies: Ethical Recommendations.

Purpose Of The Review: Experiences of patients, families, healthcare workers and health systems during the COVID-19 pandemic and recent national focus on racial justice have forced a reconsideration of policies and processes of providing care in crisis situations when resources are scarce. The purpose of this review is to present recent developments in conceptualizing ethical crisis standards.

Recent Findings: Several recent papers have raised concerns that "objective" scarce resource allocation protocols will serve to exacerbate underlying social inequities.

Health Professionals Palliative Care Education for Older Adults: Overcoming Ageism, Racism, and Gender Bias.

Purpose Of Review: Most aging Americans lack access to specialist palliative care aimed at those experiencing serious illness and/or high symptom burden at end of life. The curricula used by training programs for all healthcare professions should focus on helping learners develop the primary palliative care skills and competencies necessary to provide compassionate bias-free care for adults with serious illness. We believe there is much opportunity to improve this landscape via the incorporation of palliative care competencies throughout generalist healthcare professional programs.

Rural Older Adults in Disasters: A Study of Recovery From Hurricane Michael.

Objective: This study aims for a greater understanding of how older adults (age 65 and older) in Jackson County, Florida, are prepared for and cope with the effects of a natural disaster.

Methods: A multidisciplinary, international research team developed a survey examining: (1) resources available to individuals aged 65+ in rural communities for preparing for a disaster; (2) challenges they face when experiencing a disaster; and (3) their physical, social, emotional, and financial needs when it strikes. The survey was administered with older adults (65+) in Jackson County, Florida, following Hurricane Michael in 2018.

A Mixed-Effects Model of Associations Between Interleukin-6 and Hippocampal Volume.

Previous studies report hippocampal volume loss can help predict conversion from normative aging to mild cognitive impairment to dementia. Additionally, a growing literature indicates that stress-related allostatic load may increase disease vulnerability. The current study examined the relationship between stress-related cytokines (ie, interleukin-6 [IL-6]), cognition as measured by Mini-Mental State Examination (MMSE) scores, and hippocampal volume.

Exploring Individuals' Willingness to Engage in Interventions to Improve Cognitive Health and Prolong Late-Life Independence: An Extension of Harrell, Kmetz, and Boot (2019).

Interventions designed to preserve cognition have become increasingly popular as our population ages. In exploring intervention effectiveness, however, researchers have often overlooked a potentially important factor: willingness to engage. Recent findings from Harrell, Kmetz, Boot (2019) showed that perceived cognitive deficits and perceived training efficacy were significant predictors of willingness to engage in a brain training intervention designed to preserve cognition.

Investigating message framing to improve adherence to technology-based cognitive interventions.

A cognitive intervention study was conducted with the purpose of exploring methods to improve adherence to a technology-based cognitive intervention and uncover individual differences that predict adherence (N = 120). The study was divided into two phases: Phase 1, in which participants were asked to follow a prescribed schedule of training that involved gamified neuropsychological tests administered via tablet, and Phase 2, in which participants were asked to play as frequently as they wished. Positive- and negative-framed messages about brain health were delivered via the software program, and measures of cognition, technology proficiency, self-efficacy, technology attitudes, and belief in the benefits of cognitive training were collected.
