A Systematic Review and Meta-Analysis of Social Cognition Among People Living with HIV: Implications for Non-Social Cognition and Social Everyday Functioning.

Social cognition-the complex mental ability to perceive social stimuli and negotiate the social environment-has emerged as an important cognitive ability needed for social functioning, everyday functioning, and quality of life. Deficits in social cognition have been well documented in those with severe mental illness including schizophrenia and depression, those along the autism spectrum, and those with other brain disorders where such deficits profoundly impact everyday life. Moreover, subtle deficits in social cognition have been observed in other clinical populations, especially those that may have compromised non-social cognition (i.e., fluid intelligence such as memory). Among people living with HIV (PLHIV), 44% experience cognitive impairment; likewise, social cognitive deficits in theory of mind, prosody, empathy, and emotional face recognition/perception are gradually being recognized. This systematic review and meta-analysis aim to summarize the current knowledge of social cognitive ability among PLHIV, identified by 14 studies focused on social cognition among PLHIV, and provides an objective consensus of the findings. In general, the literature suggests that PLHIV may be at-risk of developing subtle social cognitive deficits that may impact their everyday social functioning and quality of life. The causes of such social cognitive deficits remain unclear, but perhaps develop due to (1) HIV-related sequelae that are damaging the same neurological systems in which social cognition and non-social cognition are processed; (2) stress related to coping with HIV disease itself that overwhelms one's social cognitive resources; or (3) may have been present pre-morbidly, possibly contributing to an HIV infection. From this, a theoretical framework is proposed highlighting the relationships between social cognition, non-social cognition, and social everyday functioning.

Does Olfactory Training Improve Brain Function and Cognition? A Systematic Review.

Olfactory training (OT), or smell training,consists of repeated exposure to odorants over time with the intended neuroplastic effect of improving or remediating olfactory functioning. Declines in olfaction parallel declines in cognition in various pathological conditions and aging. Research suggests a dynamic neural connection exists between olfaction and cognition. Thus, if OT can improve olfaction, could OT also improve cognition and support brain function? To answer this question, we conducted a systematic review of the literature to determine whether there is evidence that OT translates to improved cognition or altered brain morphology and connectivity that supports cognition. Across three databases (MEDLINE, Scopus, & Embase), 18 articles were identified in this systematic review. Overall, the reviewed studies provided emerging evidence that OT is associated with improved global cognition, and in particular, verbal fluency and verbal learning/memory. OT is also associated with increases in the volume/size of olfactory-related brain regions, including the olfactory bulb and hippocampus, and altered functional connectivity. Interestingly, these positive effects were not limited to patients with smell loss (i.e., hyposmia & anosmia) but normosmic (i.e., normal ability to smell) participants benefitted as well. Implications for practice and research are provided.

"As I Grew Older, My Life Got Better": Conceptions of Successful Aging among Older Women Living with or at Risk of HIV.

Successful aging (SA) is an important target for HIV care. However, we have insufficient understanding of how older women living with HIV (OWLH) in the US define SA. We explored conceptions of SA by OWLH and older women at risk of HIV and examined whether SA conceptions differed by (1) HIV serostatus, and (2) participation in the Women's Interagency HIV Study (WIHS). These analyses were part of a larger mixed-methods study with a sequential design. Participants were recruited at two clinical WIHS sites. We enrolled both WIHS participants and non-WIHS clinic patients. Our sample was 84% Black and included 29 OWLH and 15 older women at risk of HIV. We conducted 21 semi-structured interviews and four focus groups. The dataset was analyzed using descriptive, comparative, and relational analysis. We found four interlinked themes: life course perspective, accepting and celebrating aging, taking care of yourself, and looking good. The life course perspective was a core theme: participants assessed their aging in comparison to their earlier life hardships. These themes were similarly present among OWLH and older women at risk of HIV, although OWLH emphasized taking care of HIV. SA conceptualizations by OWLH did not differ whether or not they participated in the WIHS. Women living with or at risk of HIV may experience severe hardships throughout their lives. Overcoming these hardships may be linked to SA. Assessing the needs and connecting women to resources and programs are critical for SA promotion.

Cognitive prescriptions for reducing dementia risk factors among Black/African Americans: feasibility, acceptability, and preliminary efficacy.

OBJECTIVES: Black/African Americans (B/AAs) have double the risk of Alzheimer's disease and related dementia than Whites, which is largely driven by health behaviors. This study examined the feasibility, acceptability, and preliminary efficacy of a pilot randomized clinical trial of an individualized multidomain health behavior intervention among middle-aged and older B/AAs (dubbed Cognitive Prescriptions [CogRx]). DESIGN: Thirty-nine community-dwelling B/AA participants aged 45-65 without significant cognitive impairment were randomized to one of three groups: CogRx, Psychoeducation, or no-contact control. The Psychoeducation and CogRx groups received material on dementia prevalence, prognosis, and risk factors, while the CogRx group additionally received information on their risk factor profile across the five CogRx domains (physical, cognitive, and social activity, diet, sleep). This information was used for developing tailored 3-month goals in their suboptimal areas. RESULTS: The CogRx program had high retention (all 13 CogRx participants completed the 3-month program and 97% of the full sample completed at least 1 follow-up) and was well-received as exhibited by qualitative and quantitative feedback. Themes identified in the positive feedback provided by participants on the program included: increased knowledge, goal-setting, personalization, and motivation. The COVID-19 pandemic was a consistent theme that emerged regarding barriers of adherence to the program. All three groups improved on dementia knowledge, with the largest effects observed in CogRx and Psychoeducation groups. Increases in cognitive, physical, and overall leisure activities favored the CogRx group, whereas improvements in sleep outcomes favored Psychoeducation and CogRx groups as compared to the control group. CONCLUSION: The CogRx program demonstrated feasibility, acceptability, and preliminary efficacy in increasing dementia knowledge and targeted health behaviors. Further refinement and testing of the implementation and effectiveness of similar person-centered dementia prevention approaches are needed on a larger scale in diverse populations. Such findings may have implications for clinical and public health recommendations. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03864536.

Chronic Pain Resilience Across Clinical Populations: A Concept Analysis.

BACKGROUND: Chronic pain resilience is a concept that is frequently used in research but lacks theoretical clarity. Understanding chronic pain resilience is germane to developing interventions to improve it and the overall quality of life among individuals with chronic pain. AIMS: To uncover and clarify the unique characteristics of the concept of chronic pain resilience. DESIGN: A concept analysis using Rodgers' evolutionary method. METHODS: Full-text articles published after 2000 in English were used to inform the concept analysis. Scopus, PubMed, PsychINFO, Embase, and CINAHL Plus with Full Text were utilized for literature searches. Rodgers' evolutionary approach was used to clarify the attributes, antecedents, and consequences. RESULTS: The search yielded 31 articles that were used in the analysis. The key attributes of chronic pain resilience included engagement in meaningful activities despite pain, maintaining positive psychological homeostasis, buffering against negative mental outcomes, seeking support, and self-empowerment. After considering surrogate terms, antecedents, attributes, and consequences, chronic pain resilience may be defined as the development of the capacity to successfully adapt to chronic pain. This adaptation results in a move toward optimal social, physical, mental, and behavioral functioning by balancing negative and positive psychosocial factors, despite the additional challenges brought about by living with chronic pain.

Tools for Screening and Measuring Anxiety Among Women Living with HIV of Reproductive Age: A Scoping Review.

Emerging evidence suggests that women living with HIV (WLWH) may experience higher rates of anxiety than men living with HIV and women living without HIV. To date, relatively little knowledge exists on valid anxiety screening and diagnostic tools and how they are used among WLWH, specifically WLWH of reproductive age. Thus, the purpose of this scoping review was to describe what is known in the published literature about anxiety among WLWH and the tools used to measure and screen for anxiety in clinical and research contexts. The Arksey and O'Malley methodological framework was used to guide a scoping review of published articles in PsycINFO, Scopus, Sociological Abstracts, and PubMed databases. Twenty-one measures of anxiety were used across the 52 articles identified in the search. Most measures used were self-report. Inconsistencies in standardized screening tools and cutoff scores were observed across studies. Further, measures to assess anxiety varied among studies focused on WLWH. Based on the results from this review, there is a need for consistent, valid measures of anxiety to advance research and clinical practice to support the well-being of WLWH.

The Association Between Objectively-Measured Physical Activity and Cognitive Functioning in Middle-Aged and Older People Living with HIV.

Middle-aged and older people living with HIV (PWH) are at higher risk for cognitive impairment and engage in lower levels of physical activity (PA) than seronegative counterparts. Research examining the association between objectively-measured PA and cognitive function in this population is scarce. This cross-sectional study examined the association between accelerometry-measured PA and cognitive functioning among 75 PWH (mean age 55.63). Light PA was the PA variable with the most consistent associations with cognition, with more minutes per week of light PA (performed in bouts of ≥ 10 min) being associated with better executive function, working memory/attention, and speed of processing performance, adjusted for age and current CD4 count. Findings suggest that although middle-aged and older PWH engage in more light than moderate-to-vigorous PA, light PA may be beneficial to cognition. Longitudinal studies are needed to understand PA dose-response associations with cognitive trajectories, cognitive domain specificity of PA effects, and underlying neural mechanisms of PA.

Resilience in the context of dementia family caregiver mental health: A concept analysis.

Resilience has been identified as a key concept for dementia family caregiver mental health; however, the concept is not well defined. A concept analysis examining dementia caregiver resilience was conducted using Rodger's Evolutionary Method. The aim of this concept analysis was to describe the historical perspective, attributes, antecedents, and consequences of resilience as it relates to dementia caregiver mental health. Key attributes of dementia caregiver resilience were acceptance, coping strategies, social support, self-appraisal, and spirituality. The results from this concept analysis provide the foundation for the development of resilience-based interventions to support the well-being of dementia family caregivers.

Cognitive Intra-individual Variability in HIV: an Integrative Review.

Nearly 30-50% of people living with HIV experience HIV-Associated Neurocognitive Disorder (HAND). HAND indicates performance at least one standard deviation below the normative mean on any two cognitive domains. This method for diagnosing or classifying cognitive impairment has utility, however, cognitive intraindividual variability provides a different way to understand cognitive impairment. Cognitive intraindividual variability refers to the scatter in cognitive performance within repeated measures of the same cognitive test (i.e., inconsistency) or across different cognitive tests (i.e., dispersion). Cognitive intraindividual variability is associated with cognitive impairment and cognitive decline in various clinical populations. This integrative review of 13 articles examined two types of cognitive intraindividual variability in people living with HIV, inconsistency and dispersion. Cognitive intraindividual variability appears to be a promising approach to detect subtle cognitive impairments that are not captured by traditional mean-based neuropsychological testing. Greater intraindividual variability in people living with HIV has been associated with: 1) poorer cognitive performance and cognitive decline, 2) cortical atrophy, both gray and white matter volume, 3) poorer everyday functioning (i.e., driving simulation performance), specifically medication adherence, and 4) even mortality. This inspires future directions for research. First, greater cognitive intraindividual variability may reflect a greater task demand on executive control to harness and regulate cognitive control over time. By improving executive functioning through cognitive training, it may reduce cognitive intraindividual variability which could slow down cognitive decline. Second, cognitive intraindividual variability may be reconsidered in prior cognitive intervention studies in which only mean-based cognitive outcomes were used. It is possible that such cognitive interventions may actually improve cognitive intraindividual variability, which could have clinical relevance.

Transportation Barriers and Health-Related Quality of Life in a Sample of Middle-Aged and Older Adults Living with HIV in the Deep South.

Access to reliable transportation is a social determinant of health imperative for disease management for those aging with HIV/AIDS. To what degree transportation barriers are associated with health-related quality of life (HRQOL) in middle-aged and older people living with HIV (PWH) in the Deep South region of the United States is presently unknown. PWH (n = 261, age range = 39 to 73 years old, 80.1% African American, 64.4% male) were recruited from an academic medical center in the Deep South. Variables included sociodemographics, HIV characteristics, depressive symptoms, HRQOL, and perceived transportation barriers. Spearman rho correlations and linear regressions accounting for covariates were conducted. After accounting for covariates, greater perceived transportation barriers were associated with worse health perceptions, pain, social functioning, health distress, and health transitions. Access to reliable transportation is a key factor in improving health for PWH. Considerations for healthcare and traffic safety are discussed.

Emerging directions of cognitive aging with HIV: practice and policy implications for social work.

Cognitive impairments have been endemic to the HIV epidemic since its beginning and persist to this day. These impairments are attributed to HIV-induced neuroinflammation, the long-term effects of combination antiretroviral therapy, lifestyle factors (e.g., sedentary behavior, substance use), neuro-comorbidities (e.g., depression), age-associated comorbidities (e.g., heart disease, hypertension), and others causes. Normal aging and lifestyle also contribute to the development of cognitive impairment. Regardless of the etiology, such cognitive impairments interfere with HIV care (e.g., medication adherence) and everyday functioning (e.g., driving safely, financial management). With more than half of people with HIV (PWH) 50 years and older, and ~45% of all PWH meeting the criteria for HIV-Associated Neurocognitive Disorder (HAND), those aging PWH are more vulnerable for developing cognitive impairment. This article provides an update to a social work model to identify and monitor PWH for cognitive impairment. Within this update, the state of the science on protecting brain health and cognitive reserve within the context of neuroHIV is also presented. From this, implications for practice and policy to promote successful cognitive functioning in older PWH are provided.

Psychosocial Mechanisms of Self-rated Successful Aging with HIV: A Structural Equation Model.

This study tested a conceptual psychosocial model of self-rated successful aging (SRSA) with HIV. Our sample (n = 356) included older women living with HIV (OWLH): average age 56.5 years, 73% Black. SRSA was assessed using a research-based 10-point scale (higher scores = better outcomes). We conducted adjusted structural equation modeling. The global model included two latent variables-protective attributes (composite of positive psychosocial factors: resilience, personal mastery, optimism, spirituality) and psychological distress (composite of negative psychosocial factors: anxiety, depression, loneliness, internalized HIV-related stigma). The model showed good fit (χ2(58) = 76, p = 0.06; RMSEA = 0.03; CFI = 0.99). Increased protective attributes were associated with improved SRSA both directly and mediated by improved coping with stress. While psychological distress did not have a direct effect on SRSA, it was indirectly associated with worsened SRSA via diminished protective attributes and via decreased coping with stress. Findings suggest the need for interventions enhancing positive and mitigating negative psychosocial factors in OWLH.

Can Individualized-Targeted Computerized Cognitive Training Benefit Adults with HIV-Associated Neurocognitive Disorder? The Training on Purpose Study (TOPS).

Half of people with HIV (PWH) have HIV-associated neurocognitive disorder (HAND). This study examined whether cognition can be improved using a framework targeting impaired individual cognitive domains in PWH with HAND. In this two-group pre-post experimental design study, 88 adults with HAND were randomized to either: (1) a no-contact control group (n = 40) or (2) the Individualized-Targeted Cognitive Training group (n = 48). Baseline cognitive performance was assessed on eight cognitive domains. A theoretical framework was used to determine the two cognitive domains selected for training. With priority on speed of processing (SOP) and attention impairments, participants received SOP and/or attention training if such impairments were detected; if not, participants were assigned to cognitive training in one/two of the least impaired cognitive domains contributing to their HAND diagnosis. Global cognitive score was slightly improved following training (p = 0.256; d = - 0.21), but it was not significant. Significant improvements were observed on SOP following training in that domain (SOP; d = - 0.88; p = 0.011). SOP training also improved functioning in other cognitive domains. This individualized cognitive intervention did not change HAND status, but it did result in improved SOP, in turn yielding improvement in other cognitive domains.

Intracellular Tenofovir and Emtricitabine Concentrations in Younger and Older Women with HIV Receiving Tenofovir Disoproxil Fumarate/Emtricitabine.

The altered immune states of aging and HIV infection may affect intracellular metabolism of tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC); increased cellular senescence decreases FTC-triphosphate (FTCtp) concentrations. The effects of age and inflammation on the ratio of intracellular metabolites (IMs; tenofovir diphosphate [TFVdp] and FTCtp) to their endogenous nucleotides (ENs; dATP and dCTP), a potential treatment efficacy marker, were assessed among participants of the Women's Interagency HIV Study (WIHS), who ranged from 25 to 75 years. Samples from women receiving TDF-FTC with viral loads of <200 copies/ml were dichotomized by age at collection into two groups (≤45 years and ≥60 years). IM/EN concentrations were measured in peripheral blood mononuclear cell (PBMC) pellets; interleukin-6 (IL-6) and sCD163 were measured in plasma; senescent CD8+ T cells were measured in viable PBMCs. The TFVdp:dATP and FTCtp:dCTP ratios had statistically significantly different distributions in older and younger women (log-rank test, P = 0.0023 and P = 0.032, respectively); in general, IM and EN concentrations were higher in the older women. After adjusting for potential confounders, these findings were not significant. In women aged ≤45 years, TFVdp was negatively associated with IL-6 and sCD163, while FTCtp was positively associated with sCD163 and IL-6 in women aged ≥60 years. Body mass index (BMI) was positively associated with IL-6 in both age groups and negatively associated with TFVdp in women aged ≤45 years. After adjustment, age remained significant for sCD163, while black race, BMI, and renal function remained significant for several IMs and ENs, suggesting that factors associated with aging, but not age itself, govern intracellular TDF-FTC pharmacology.

Successful Functional Aging in Middle-Aged and Older Adults with HIV.

People living with HIV (PLWH) experience greater everyday functioning impairment. We examined frequency and correlates of successful functional aging (SFA) in PLWH. Using gold-standard questionnaires, SFA was defined in 174 HIV+ and 71 HIV- adults as absence of significant everyday cognitive symptoms and declines in instrumental activities of daily living. More HIV- (45%) than HIV+ (18%) adults met SFA criteria (p < 0.01). Depression, cognitive functioning, socioeconomic status, and HIV status were independent correlates of SFA (p values < 0.05). Motor ability, learning, and verbal fluency were associated with SFA. SFA was associated with health-related quality of life (HRQoL). PLWH are three times less likely to achieve SFA than HIV- adults, a phenotype that translates to HRQoL. While SFA is multifactorial, driven by clinico-demographic factors, HIV may pose additional risk to achieving SFA. Further work should examine other mechanisms whereby HIV hinders SFA (e.g., biomarkers, stress, mental health) and ultimately inform interventions to facilitate SFA.

Critical, and not functional, health literacy is associated with missed HIV clinic visits in adults and older adults living with HIV in the Deep South.

Engagement in care is a key component of the HIV treatment cascade and is influenced by biopsychosocial factors. Little is known about the association of health literacy with this impactful outcome in people living with HIV (PLWH). Ninety-five PLWH completed a comprehensive battery including health literacy measures covering several domains (i.e., numeracy, reading, self-efficacy, and ability to appraise and access health information). Engagement in care was operationalized as missed clinic visits (i.e., proportion of clinic visits in the prior 24 months where the participant did not attend and did not cancel or reschedule). The ability to appraise health information (measured by the Newest Vital Sign [NVS]) was the only significant health literacy predictor of missed clinic visits. Hierarchical linear regression including clinico-demographics and all health literacy variables showed that age, depression, neurocognition, and NVS were significant (p < 0.05) correlates of missed clinic visits. The ability to appraise health information was a strong and independent predictor of missed clinic visits in PLWH, even in the context of traditional correlates. Such measures may be useful in identifying PLWH with low health literacy who may be at risk for poorer engagement in care. Future research developing interventions targeting this health literacy dimension are warranted.

Barriers to HIV Testing: Patient and Provider Perspectives in the Deep South.

Although CDC guidelines call for universal, "opt-out" HIV testing, barriers to testing continue to exist throughout the United States, with the rural South particularly vulnerable to both HIV infection and decreased awareness of status. Therefore, the objectives of this study were to evaluate uptake of "opt-out" HIV testing and barriers to testing within the primary care setting in the South. A concurrent triangulation design guided the collection of quantitative data from patients (N = 250) and qualitative data from providers (N = 10) across three primary health clinics in Alabama. We found that 30% of patients had never been tested for HIV, with the highest ranked barrier among patients being perceived costs, access to specialty care, and not feeling at risk. Significant differences existed in perceived barriers between patients and providers. Increased provider-patient engagement and the routine implementation of "opt-out" HIV testing would effectively reveal and mitigate barriers to testing, thus, increasing awareness of status.

Resilience attenuates the association between neurocognitive functioning and everyday functioning in individuals aging with HIV in the Deep South.

OBJECTIVES: Adults aging with HIV are at risk for poorer neurocognitive and daily functioning. Identifying factors to protect such outcomes is a significant research priority. The aim of this study was to explore the role of resilience in cognitive and everyday functioning in a largely African American and low socioeconomic status sample of adults and older adults with HIV in the Deep South. METHODS/DESIGN: In this cross-sectional study 100 HIV+ middle-aged and older adults (range 40-73; 61% aged 50+) completed a comprehensive neurocognitive battery along with self-reported measures of resilience and everyday functioning. RESULTS: Higher resilience was associated with better global neurocognitive functioning (rho = 0.31, P < 0.01), as well as better functioning in all domains (verbal fluency, executive functioning, speed of information processing, learning, working memory) except recall and motor skills. Resilience was also significantly associated with instrumental activities of daily living (IADL) dependence, with lower resilience observed in those with IADL dependence compared with those who were IADL independent (P < 0.01). In a multiple regression adjusting for data-driven covariates (verbal IQ, income, depression), and global neurocognitive impairment, resilience was the only significant (P = 0.02) correlate of IADL dependence. A follow-up mediation showed that the direct relationship between neurocognitive functioning and IADL declines was fully attenuated after accounting for shared variance with resilience. CONCLUSIONS: Resilience is associated with better cognitive and functional outcomes in people aging with HIV. While further work is needed to understand these associations over time, results suggest interventions to build resilience may promote successful aging in this vulnerable population.

Sleep following traumatic brain injury (TBI): experiences and influencing factors.

Objective: This study aimed to 1) describe and explore the experiences of sleep following a moderate or severe traumatic brain injury (TBI) in community-dwelling adults, 2) elicit factors that positively or negatively impact the sleep experience, and 3) understand sleep-related education provided to survivors.Design: Qualitative description.Methods: Face-to-face interviews with 16 individuals using a semi-structured interview guide. Transcripts were systematically coded and common themes were identified. The final sample consisted of primarily Caucasian men with average age of 32.4 years (SD = 9.9), and average of 2.6 years (SD = .89) years post injury.Results: Community-dwelling survivors of TBI experienced poor sleep quality and quantity post-injury and described a variety of approaches to manage their sleep. Survivors described coping with sleep changes and using sleep as a coping mechanism for TBI. Additionally, survivors' responses indicated perceived lack of resources and preference for receiving education from knowledgeable, familiar clinicians during face-to-face encounters.Conclusions: This study provides a description of reported sleep experiences following TBI and adds new knowledge regarding sleep management strategies and preferences for resources. The findings suggest a need for education regarding sleep for rehabilitation professionals and long-term sleep support after discharge from rehabilitation.

Anxiety of Active and Passive Role Groups in Clinical Simulation: A Pilot Study.

Clinical simulation within nursing programs is a hallmark teaching strategy. With faculty challenged to design effective simulations for large groups of students, students are often divided into an active or passive role group. This study examined the anxiety levels experienced by students in the two roles. Results indicated that trait anxiety was similar in both groups before and after the simulation; however, there was a significant decrease in state anxiety ratings in the active role group following the simulation. The finding that students in the active role group experienced reduced state anxiety can theoretically facilitate learning.
