Preventing Cognitive Decline in Older Latino Adults With HIV Through a Culturally Tailored Health Promotion Intervention: Protocol for a Single-Arm Pilot Trial.

BACKGROUND: Older Latino adults with HIV are at increased risk for mild cognitive impairment and earlier onset of aging-related cognitive decline. Improvements in cognitive functioning and cognitive outcomes are possible among people with HIV who adopt health promotion behaviors. However, health promotion interventions for older Latino adults with HIV have not been extensively used or widely recognized as viable treatment options. Happy Older Latinos are Active (HOLA) is a multicomponent, health promotion intervention that is uniquely tailored for older Latino adults with HIV. OBJECTIVE: This study aims to (1) determine the feasibility and acceptability of an adapted version of HOLA aimed at improving cognitive functioning among older Latino adults with HIV; (2) explore whether HOLA will produce changes in cognitive functioning; (3) explore whether HOLA will produce changes in activity, psychosocial functioning, or biomarkers of cognition; and (4) explore whether changes in activity, psychosocial functioning or cognitive biomarkers correlate with changes in cognition, while accounting for genetic risk for dementia. METHODS: A single-arm pilot trial with 30 Latino (aged 50 years and older) men and women with HIV was conducted to assess feasibility, acceptability, and preliminary effects on cognition. Participants were assessed at 2 time points (baseline and postintervention) on measures of neurocognitive and psychosocial functioning. In addition, blood samples were collected to determine biomarkers of cognition at baseline and postintervention. Successful recruitment was defined as meeting 100% of the targeted sample (N=30), with 20% (n=6) or less of eligible participants refusing to participate. Adequate retention was defined as 85% (n=25) or more of participants completing the postintervention assessment and acceptability was defined as 80% (n=38) or more of sessions attended by participants. RESULTS: Participant recruitment began on February 22, 2022, and was completed on August 15, 2022. The last study visit took place on February 20, 2023. Data analysis is currently ongoing. CONCLUSIONS: Encouraging findings from this exploratory study may provide a blueprint for scaling up the HOLA intervention to a larger cohort of older Latino adults with HIV who may be currently experiencing or are at risk for HIV-related cognitive challenges.

Substance use moderates relationships between apolipoprotein E genotype, hepatitis C, cognition, and depression in Miami Adult Studies on HIV (MASH) participants.

The impact of APOE on HIV and HCV disease course, cognition, and memory has been understudied in minoritized populations. This study examined whether scores on cognition and depression measures differed by APOE ε4 carrier status while considering HCV and HIV seropositivity and whether these measures were moderated by substance use. A retrospective analysis examined cognitive and psychological data from participants (n = 493) in the Miami Adult Studies on HIV (MASH) cohort. APOE genotyping was performed on banked blood samples. Multiple linear regression was employed to examine differences across participants living with and without HIV and/or HCV and by APOE ε4 genotype. APOE ε4 carriers living with HCV who used cannabis had higher depression scores than non-ε4 carriers, while nonusers had fewer depressive symptoms. APOE ε4 carriers living with HCV had better cognition scores after adjusting for cocaine, opiate, and cannabis use than non-ε4 carriers. Scores on cognitive and depression measures did not differ between APOE ε4 carriers and non-ε4 carriers in participants living with HIV, and substance use did not moderate this relationship. This study was the first of its kind to examine substance use as a moderator for cognition and depression among individuals with HIV and/or HCV stratified by APOE genotype. Findings support further research evaluating the frequency and duration of 1) domains of cognitive functioning impacted by APOE genotype relevant to substance use and 2) the influence of substance use on cognitive and depressive outcomes among adults living with HIV and HCV, HIV, or HCV.

Examining the relationship between anxiety and regional brain volumes in the National Alzheimer's Coordinating Center uniform, imaging, and biomarker datasets.

Anxiety has been associated with a greater risk of Alzheimer's disease (AD). Existing research has identified structural differences in regional brain tissue in participants with anxiety, but results have been inconsistent. We sought to determine the association between anxiety and regional brain volumes, and the moderation effect of APOE ε4. Using data from participants in the National Alzheimer's Coordinating Center (NACC) Uniform Data Set, with complete imaging (MRI) and biomarker data (n = 1533), multiple linear regression estimated the adjusted effect of anxiety on 30 structural MRI regions. The moderation effect of APOE ε4 on the relation between structural MRI regions and anxiety was assessed as was the moderation effect of cognitive status. False discovery rate was used to adjust for multiple comparisons. After controlling for intracranial volume, age, sex, years of education, race, Hispanic ethnicity, and cognitive status, seven MRI regions demonstrated lower volumes among participants with anxiety: total cerebrum gray matter volume, right hippocampus volume, hippocampal volume (total), right and left frontal lobe cortical gray matter volume, and right and total temporal lobe cortical gray matter volume. Findings suggest that anxiety is associated with significant atrophy in multiple brain regions, with corresponding ventricular enlargement. Future research should investigate if anxiety-related changes to brain morphology contribute to greater AD risk.

Financial Planning Among Parents of Children With Intellectual and Developmental Disabilities.

Families of children with intellectual and developmental disabilities (IDD) experience significant financial hardship, which could improve through financial planning and utilization of accounts such as the Achieving a Better Life Experience (ABLE). Unfortunately, current rates of banking are low among individuals with disabilities, and no study has examined this phenomenon specifically among families of children with IDD. In this cross-sectional study, 176 parents shared their financial planning and utilization experience. Findings indicate that parents worry about their child's financial future, however, paradoxically, are not engaging in financial planning. Utilization of ABLE, checking and savings accounts, and special needs trusts are also low. Parents reported several programmatic and personal barriers which could inform immediate programmatic changes and long-term policy considerations.

Stress and Anxiety Among Parents of Transition-Aged Children with Autism Spectrum Disorder: a Systematic Review of Interventions and Scales.

The period between adolescence to young adulthood can be stressful for parents of transition-aged children (14 to 22 years old) with autism spectrum disorder. A systematic review was undertaken to examine if existing interventions address the unique parental stressors of this phase and if the scales used to measure parental stress and anxiety are suitable for this group. Of the 9813 studies screened, only 13 studies met the inclusion criteria. Findings indicated that interventions focused on mindfulness, social functioning, or multiple components, of which only two addressed the transition period and only three specifically targeted parents of this age group. Moreover, of the six scales which assessed stress or anxiety, none were designed for these parents. Findings highlight the urgent need for more suitable scales and targeted interventions.

The Mediating Effect of Maternal Wellbeing on the Association between Neighborhood Perception and Child Wellbeing: A Longitudinal Investigation.

OBJECTIVES: Negative perceptions of one's neighborhood are linked to poor mental and physical health. However, it is unclear how caregiver's neighborhood perception affects health outcomes in children. This study assessed the mediating effect of maternal wellbeing on the association between neighborhood perception and child wellbeing at different time points and overall. METHOD: A structural equation model (SEM) was used to evaluate whether maternal wellbeing mediates the influence of neighborhood perception on child wellbeing at different ages. The Fragile Families and Child Wellbeing Study data from years 3, 5, and 9 was analyzed. The delta method evaluated the mediation effect of maternal wellbeing, controlling for mothers' age. Direct and indirect effects of neighborhood perception at year 3 on child wellbeing at year 9 via maternal wellbeing at year 5 were analyzed via a longitudinal mediation with a two time points lag. RESULTS: Maternal wellbeing partially mediated the effect of neighborhood perception on child wellbeing at different ages. Longitudinal mediation analyses revealed that better neighborhood perception at year 3 improved maternal wellbeing at year 5 and child wellbeing at year 9; maternal wellbeing at year 5 partially mediated the effect of neighborhood perception at year 3 on child wellbeing at year 5. CONCLUSIONS FOR PRACTICE: Our findings suggest that it may be beneficial for mental health practitioners to discuss relationships between neighborhood environment and wellbeing with caregivers, with a focus on reframing negative self-perceptions. Future research should evaluate longitudinal relationships between changes in neighborhood infrastructure and corresponding wellbeing in caregivers and children.

Attending to the Psychosocial Needs of Older Hispanic, Black and Non-Hispanic White Women and Their Breast Cancer Screening Behaviors.

BACKGROUND: Cancer risk increases with age. Despite breast cancer screening guidelines, older minorities are less likely to obtain screenings. Many factors influence cancer screening participation, though the literature rarely examines factors influencing cancer screening in older adult minority populations. METHODS: Using 2008 and 2012 waves of data from the Health and Retirement study, we examined and compared the relationships between psychosocial factors and breast screening participation among older African American, Hispanic and non-Hispanic White women. We utilized logistic regression to determine the influence of psychosocial factors (satisfaction with aging, religiosity, perceived control, emotions, purpose in life) in 2008 predicting breast cancer screening participation in 2012, given the increasing importance of understanding health behaviors as predicted by prior circumstances. While controlling for other variables, the major findings demonstrated that the odds of having a mammogram among Hispanics decreased as feelings that 'things were getting worse' with age intensified; and screening was more likely among Hispanic religious women. The odds of obtaining a mammogram increased with increasing purpose in life for Hispanics. CONCLUSIONS AND IMPLICATIONS: These findings suggest the need for comprehensive geriatric assessments to understand the perspectives of older minority women, and provides formative data to inform shared decision-making interventions.

Examining the Family Support Role of Older Hispanics, African Americans, and Non-Hispanic Whites and Their Breast Cancer Screening Behaviors.

Disparities in breast cancer mortality rates among older Black and Hispanic women are due in part to low participation in cancer screening. Participation in cancer screening could be affected by an array of factors, including social support. Understanding the complex interplay between social support and breast cancer screening among older female adults, specifically among groups with higher mortality rates, is extremely important for timely and appropriate interventions to increase survival rates. Thus, utilizing the social network theory as the conceptual framework, this study aims to examine effects of social support on receiving a mammogram among a representative sample of older adults, specifically African American and Hispanic populations in the United States. Logistic regression models were conducted using the 2008 and 2012 Health and Retirement Study data. Findings from this study indicate that specific aspects of social support influence breast cancer screening participation among older Hispanic and non-Hispanic White women. However, this was not the case for the older Black women after adjusting for the sociodemographic factors. Given the role that family members play in the care of older adults, it is critical that social workers consider both the possible positive and negative interactions older women may have and how these interactions may affect their cancer screening behaviors. Findings can provide formative data to develop public health and social work interventions to increase positive social support and reduce negative social support by spouses and children to enhance breast cancer screening among older adults.

How Robust is the Evidence for a Role of Oxidative Stress in Autism Spectrum Disorders and Intellectual Disabilities?

Growing interest in the pathogenesis of autism spectrum disorders (ASDs) and other intellectual and developmental disabilities (IDD) has led to emerging evidence implicating a role for oxidative stress. However, understanding the strength of this association is made challenging by the use of a variety of purported biomarkers of oxidative stress, many of which have either uncertain specificity or flawed methods of analysis. This review aims to address this issue, which is widespread in the ASD and IDD literature, by providing readers with information concerning the strengths and limitations of the choice and analysis of biomarkers of oxidative stress. We highlight that biomarkers and assays should be specific, sensitive, reproducible, precise, robust, and chosen with careful consideration. Future studies should be sufficiently powered and address sample collection, processing, and storage which are, additionally, poorly considered, sources of bad practice, and potential errors. Only with these issues considered, will the data lead to conclusions as to the precise role of oxidative stress in ASDs and IDD.

The Utility of Cognitive Screeners in the Detection of Dementia Spectrum Disorders in Spanish-Speaking Populations.

Increasing rates of dementia spectrum disorders among Spanish-speaking geriatric populations necessitate the development of culturally appropriate cognitive screening tests that can identify neurodegenerative disorders in their earliest stages when emerging disease-modifying treatments are most likely to be effective. This scoping review identified 26 brief Spanish language cognitive screening tools (<20 minutes) by searching academic databases using a combination of search terms. Results suggest that the Mini-Mental Status Examination and Montreal Cognitive Assessment appear to be less valid than other screeners. Instruments such as the 7-Minute Screen and Mini-Cog evidence higher classification rates of dementia, while Phototest detected mild cognitive impairment at higher rates more consistently than other screeners. Different sensitivity and specificity outcomes and cutoffs were observed when the same cognitive screener was evaluated in different countries. Results indicate that it is imperative to increase nation-specific validation and normative data for these instruments to best serve diverse populations.

Mentoring Students with Intellectual and Developmental Disabilities: Evaluation of Role-Specific Workshops for Mentors and Mentees.

Transitioning to post-secondary education is often challenging for students with intellectual and developmental disabilities (IDD). To address this, Florida International University, specifically FIU Embrace, piloted the Embrace Mentoring Program (EMP), which provided unique role-specific workshops to both faculty/staff mentors, and student mentees with IDD. A mixed-method design was used to analyze knowledge acquisition and participant perceptions of the workshops. Quantitative findings indicated knowledge improvement in a key area for mentors, while qualitative data demonstrated a positive response to workshop content, and highlighted areas of improvement for future workshops. Ultimately, the results from the pilot EMP demonstrated promise in supporting students with IDD towards academic and career-related goals, by providing mentorship training to both mentors and mentees.

Brief Report: Improving Employment Interview Self-efficacy Among Adults with Autism and Other Developmental Disabilities Using Virtual Interactive Training Agents (ViTA).

This study evaluated the measurable impact of the use of virtual interactive training agents (ViTA) as a way to practice interviewing and gain confidence in responding to questions asked during job interviews. Of the total participants (n = 153), the majority were male (72.55%) with an average age of 21.71 years old (SD = 3.14 years). Autism spectrum disorders (ASDs; 64.71%) and intellectual disability (40%) were the most frequently reported diagnoses. Using a within-subjects repeated measures design, the repeated measures linear regression analysis found that the average self-efficacy score increased by 0.31 (p = 0.002), and statistically significant increases were found in all three subscales. Further development of virtual reality interventions like ViTA, that improve outcomes for adults with ASDs and other developmental disabilities, is warranted.

Timing of Immigration Effects Asset Change Among Hispanic Caregivers of Older Family Members.

Given the cultural value of family in Hispanic culture, older Hispanic immigrants are likely to have family caregivers. This study examined the economic implications of caring for older Hispanic adults regarding non-housing financial wealth over time. Using the 2008, 2010, and 2012 waves of the Health and Retirement Study (HRS) and RAND HRS data files, this study compares changes in the non-housing financial wealth between 2008 and 2012 by caregiving and immigration status among Hispanics. This study examined differences in assets between Hispanic caregivers and non-caregivers and more specifically examined the subpopulation of Hispanic caregivers who immigrated prior to and after 1968 as compared to U.S.-born caregivers to better understand the effect of the Immigration and Nationality Amendment Act of 1965 on asset change. Results indicate that caregiving itself did not have a statistically significant association with wealth, but the timing of immigration to the US had a statistically significant correlation (p < .05) with changes in the financial wealth. The findings of this study have implications for policy and program development targeting older adults and caregiving for this population.

Evaluating a Postsecondary Education Program for Students with Intellectual Disabilities: Leveraging the Parent Perspective.

Postsecondary education (PSE) programs serving individuals with intellectual disabilities (ID) aim to improve life outcomes by increasing skills in three key areas: academics, independent living, and employment. To ensure that PSE programs are successful, ongoing evaluations are necessary. It is particularly important to gather parental perspectives given the integral role they play regarding decision making for students with ID. This qualitative study analyzed data from 58 interviews conducted with parents whose child was enrolled in a PSE program nested within a large public university. Thematic analysis with a deductive approach was the established theoretical model used to guide the analysis. Themes related to capability, opportunity, motivation, and behavior are presented, and future recommendations for PSE programs are discussed.

Health Factors as Potential Mediators of the Longitudinal Effect of Loneliness on General Cognitive Ability.

OBJECTIVE: Higher levels of loneliness in older adulthood predict cognitive decline, but research on mediating mechanisms is sparse. We examine multisystemic physiological risk, functional ability, self-rated health, depressive symptoms, and social participation as mediating processes for the association between loneliness and general cognitive ability over a 10-year follow-up in an older adult sample. METHODS: Three waves of data from 3,005 individuals (mean intake age: 69.30 (SD: 7.85) years; female = 51.61%) recruited during Wave 1 of the National Social Life, Health, and Aging Project were used to test whether hypothesized mediators collected at the 5-year follow-up explained effects of baseline loneliness on 10-year general cognitive ability. RESULTS: The relationship between baseline loneliness and 10-year general cognitive ability was not mediated by multisystemic physiological risk. Functional ability (b = -0.24, SE = 0.05, p <0.001), self-rated health (b = -0.08, SE = 0.02, p <0.001), depressive symptoms (b= -0.20, SE = 0.05, p <0.001), and social participation (b = -0.03, SE = 0.01, p = 0.016) significantly mediated effects. Indirect effects remained significant after adjusting for demographic covariates and 5-year general cognitive ability, except social participation. DISCUSSION: Loneliness may influence cognitive ability indirectly, signaling waning physical and psychiatric health more proximally correlated with cognitive ability. These mechanisms may serve as targets of intervention for cognitive maintenance in lonely older adults.

Disparities in healthcare transition support received by adolescents with special healthcare needs.

BACKGROUND: Transitioning to adult healthcare systems can be challenging, especially if left unaddressed for adolescents with special healthcare needs (ASHCN), such as those with autism spectrum disorder and attention-deficit/ hyperactivity disorder. While there is evidence of disparities between different demographics regarding general healthcare services, research on healthcare-specific transition planning is lacking. Thus, there is a critical need to continually investigate these disparities. METHOD: Using nationally representative data from the 2016 National Survey for Children's Health, several analyses were conducted to examine doctor-patient interactions and discussions about transitioning to adult health care. Accounting for demographic and diagnostic indicators allowed for the assessment of disparities. RESULTS: Findings revealed significant disparities between age, disability and race relative to various healthcare transition support services. CONCLUSIONS: Findings provide valuable information that can inform the development of training programmes for healthcare providers, influence policy, modify procedures and interventions and highlight the need for increased advocacy for ASHCN.

Evaluation of the Major Steps in the Conventional Protocol for the Alkaline Comet Assay.

Single cell gel electrophoresis, also known as the comet assay, has become a widespread DNA damage assessment tool due to its sensitivity, adaptability, low cost, ease of use, and reliability. Despite these benefits, this assay has shortcomings, such as long assay running time, the manipulation of multiple slides, individually, through numerous process steps, the challenge of working in a darkened environment, and reportedly considerable inter- and intra-laboratory variation. All researchers typically perform the comet assay based upon a common core approach; however, it appears that some steps in this core have little proven basis, and may exist, partly, out of convenience, or dogma. The aim of this study was to critically re-evaluate key steps in the comet assay, using our laboratory's protocol as a model, firstly to understand the scientific basis for why certain steps in the protocol are performed in a particular manner, and secondly to simplify the assay, and decrease the cost and run time. Here, the shelf life of the lysis and neutralization buffers, the effect of temperature and incubation period during the lysis step, the necessity for drying the slides between the electrophoresis and staining step, and the need to perform the sample workup and electrophoresis steps under subdued light were all evaluated.

Dementia-Related Neuropsychological Testing Considerations in Non-Hispanic White and Latino/Hispanic Populations.

Hispanic individuals are at greater risk for health disparities, less than optimal health care, and are diagnosed at later stages of cognitive impairment than white non-Hispanics. Acculturation and different attitudes toward test-taking may result in decrements in performance, especially on unfamiliar measures that emphasize speed and accuracy. Non-Hispanic individuals often outperform Hispanic individuals on cognitive and neuropsychological measures in community and clinical populations. Current neuropsychological testing may not provide accurate data related to monolingual and bilingual individuals of Hispanic descent. Testing instruments were identified by searching academic databases using combinations of relevant search terms. Neuropsychological instruments were included if they were designed to detect cognitive impairment, had an administration time of less than 45 minutes, and were available in English. Validity studies were required to employ gold standard comparison diagnostic criteria. Twenty-nine instruments were evaluated in dementia staging, global cognition, memory, memory and visual abilities, working memory and attention, verbal learning and memory, recall, language, premorbid intelligence, literacy/cognitive reserve, visuospatial, attention, problem-solving, problem solving and perception, functional assessment, and mood/daily functioning domains. Spanish-language neuropsychological instruments need to be made widely available and existing instruments to be normed in Spanish to best serve and assess diverse populations. Psychometric data were reported for neuropsychological instruments, which may be administered to Hispanic older adults presenting for evaluation related to dementia-spectrum disorders. This is one of the few reviews to provide an overview of the sensitivity and specificity of available Spanish translated neuropsychological instruments.

Current state of evidence of cannabis utilization for treatment of autism spectrum disorders.

The core symptoms and co-morbidities associated with autism spectrum disorders (ASD) affect daily living and quality of life. Existing pharmacological interventions are only able to attenuate some related symptoms but are unable to address the underlying etiologies associated with ASD. Anecdotal evidence, which claims benefit from the use of cannabis to treat symptoms among this population, has been gaining popularity as families seek solutions.This paper analyzed recent peer-reviewed literature to identify the current state of evidence regarding cannabis use for the ASD population. Systematic reviews, reports, and experimental studies were assessed to understand the current extent and nature of the evidence on the risks and benefits of cannabis use for ASD. At this time, three large-scale clinical trials are currently at varying stages of progress and publication of results. Only five small studies were identified that have specifically examined cannabis use in ASD. Given the sparse state of evidence directly assessed in this population, studies which examined effects of cannabis on shared pathological symptoms of ASD such as hyperactivity, sleep disorders, self-injury, anxiety, behavioral problems, and communication were also reviewed.Studies revealed mixed and inconclusive findings of cannabis effects for all conditions, except epilepsy. Adverse outcomes were also reported, which included severe psychosis, increased agitation, somnolence, decreased appetite, and irritability. In addition, a wide range of cannabis compositions and dosage were identified within the studies, which impact generalizability.There is currently insufficient evidence for cannabis use in ASD, which creates an urgent need for additional large-scale controlled studies to increase understanding of risks and benefits and also to examine the impact of "entourage effects." This will support discussions of treatment options between health care providers and ASD patients and their families. Evidence may lead to a desired new line of treatment or prevent adverse outcomes from unsubstantiated use amongst families aiming for symptom reduction.

Utilization of Complementary and Alternative Therapies in Youth with Developmental Disabilities.

Oxidative stress is understood to be involved in the ontology and maintenance of different developmental disabilities. Some complementary and alternative medicine (CAM) therapies have been proposed to modify this relationship by affecting oxidative stress pathways. However, it is unclear which of these CAM therapies are used among children with different developmental disabilities. This study examines the use of these therapies among 10,218 children between the ages of 4 and 17 using the 2012 Child Complementary and Alternative Medicine (CAM) Supplement of the National Health Interview Survey (NHIS) to highlight a potential avenue for intervention and prevention efforts. The results suggest that children with developmental disabilities are more likely to utilize particular CAM therapies that may alter oxidative stress pathways. Future work is needed to assess the potential moderating effect of these CAM therapies and oxidative stress levels among children with different developmental disabilities.
