The Role of Employment on Neurocognitive Reserve in Adults With HIV: A Review of the Literature

Cognitive reserve and individual differences in brain tumour patients

The aim of the paper is to determine the effects of the cognitive reserve on brain tumour patients' cognitive functions and, specifically, if cognitive reserve helps patients cope with the negative effects of brain tumours on their cognitive functions. We retrospectively studied a large sample of around 700 patients, diagnosed with a brain tumour. Each received an MRI brain examination and performed a battery of tests measuring their cognitive abilities before they underwent neurosurgery. To account for the complexity of cognitive reserve, we construct our cognitive reserve proxy by combining three predictors of patients' cognitive performance, namely, patients' education, occupation, and the environment where they live. Our statistical analysis controls for the type, side, site, and size of the lesion, for fluid intelligence quotient, and for age and gender, in order to tease out the effect of cognitive reserve on each of these tests. Clinical neurological variables have the expected effects on cognitive functions. We find a robust positive effect of cognitive reserve on patients' cognitive performance. Moreover, we find that cognitive reserve modulates the effects of the volume of the lesion: the additional negative impact of an increase in the tumour size on patients' performance is less severe for patients with higher cognitive reserve. We also find substantial differences in these effects depending on the cerebral hemisphere where the lesion occurred and on the cognitive function considered. For several of these functions, the positive effect of cognitive reserve is stronger for patients with lesions in the left hemisphere than for patients whose lesions are in the right hemisphere. The development of prevention strategies and personalized rehabilitation interventions will benefit from our contribution to understanding the role of cognitive reserve, in addition to that of neurological variables, as one of the factors determining the patients' individual differences in cognitive performance caused by brain tumours.

Environmental Enrichment Enhances Cerebellar Compensation and Develops Cerebellar Reserve

The brain is able to change its structure and function in response to environmental stimulations. Several human and animal studies have documented that enhanced stimulations provide individuals with strengthened brain structure and function that allow them to better cope with damage. In this framework, studies based on the exposure of animals to environmental enrichment (EE) have provided indications of the mechanisms involved in such a beneficial action. The cerebellum is a very plastic brain region that responds to every experience with deep structural and functional rearrangement. The present review specifically aims to collect and synthesize the evidence provided by animal models on EE exposure effects on cerebellar structure and function by considering the studies on healthy subjects and on animals exposed to EE both before and after damage involving cerebellar functionality. On the whole, the evidence supports the role of EE in enhancing cerebellar compensation and developing cerebellar reserve. However, since studies addressing this issue are still scarce, large areas of inconsistency and lack of clarity remain. Further studies are required to provide suggestions on possible mechanisms of enhancement of compensatory responses in human patients following cerebellar damage.

Biopsychosocial approach to understanding determinants of depression among men who have sex with men living with HIV: A systematic review

INTRODUCTION

Men who have sex with men (MSM) living with HIV are more likely to be depressed than MSM without HIV. The AIDS epidemic will not end if the needs of people living with HIV and the determinants of health are not being addressed. Compared to HIV individuals without depression, depressed HIV individuals have worse clinical outcomes and higher mortality risk. Depression is caused by a complex combination of social, psychological, and biological variables. This systematic review, thereby motivated by the need to address this gap in the literature, aims to articulate determinants of depression among MSM living with HIV according to the biopsychosocial approach.

METHODOLOGY

We systematically searched four databases from 2011 to 2021. We searched for observational studies on determinants of depression among MSM living with HIV. The outcome is depression based on the categorical or numerical outcome. Two reviewers independently extracted data and assessed study risks of bias. Any disagreements are consulted with the third reviewer.

RESULTS

We identified 533 articles, of which only eight studies are included. A total of 3,172 MSMs are included in the studies. We found the determinants of depression and categorized them according to biological, psychological, and social approaches.

CONCLUSION

The determinants of depression with the strongest evidence across studies were enacted HIV-related stigma, unemployment, sleep disturbance, current smoker, black ethnicity, born overseas, ART initiation, and access to mental health care. Despite weaker evidence, the other relevant determinants to be included were older age, internalized stigma, self-efficacy, and social support. Efforts to improve or prevent depression among MSM living with HIV could benefit from addressing the determinants of depression based on the biopsychosocial approach immediately after HIV diagnosis. Integrating mental health screening and care into HIV treatment settings would strengthen HIV prevention and care outcomes and improve access to mental healthcare.

Development and Validation of a Cognitive Reserve Index in HIV

OBJECTIVES

In the neuroHIV literature, cognitive reserve has most often been operationalized using education, occupation, and IQ. The effects of other cognitively stimulating activities that might be more amenable to interventions have been little studied. The purpose of this study was to develop an index of cognitive reserve in people with HIV, combining multiple indicators of cognitively stimulating lifetime experiences into a single value.

METHODS

The data set was obtained from a Canadian longitudinal study (N = 856). Potential indicators of cognitive reserve captured at the study entry included education, occupation, engagement in six cognitively stimulating activities, number of languages spoken, and social resources. Cognitive performance was measured using a computerized test battery. A cognitive reserve index was formulated using logistic regression weights. For the evidence on concurrent and predictive validity of the index, the measures of cognition and self-reported everyday functioning were each regressed on the index scores at study entry and at the last follow-up [mean duration: 25.9 months (SD 7.2)], respectively. Corresponding regression coefficients and 95% confidence intervals (CIs) were computed.

RESULTS

Professional sports [odds ratio (OR): 2.9; 95% CI 0.59-14.7], visual and performance arts (any level of engagement), professional/amateur music, complex video gaming and competitive games, and travel outside North America were associated with higher cognitive functioning. The effects of cognitive reserve on the outcomes at the last follow-up visit were closely similar to those at study entry.

CONCLUSION

This work contributes evidence toward the relative benefit of engaging in specific cognitively stimulating life experiences in HIV.

Socioeconomic, Psychosocial, and Clinical Factors Associated With Employment in Women With HIV in the United States: A Correlational Study

ABSTRACT

Employment is a social determinant of health, and women living with HIV (WLWH) are often underemployed. This correlational study examined the socioeconomic, psychosocial, and clinical factors associated with employment among WLWH (n = 1,357) and women at risk for HIV (n = 560). Descriptive and inferential statistics were used to evaluate factors associated with employment status. Employment was associated (p ≤ .05) with better socioeconomic status and quality of life (QOL), less tobacco and substance use, and better physical, psychological, and cognitive health. Among WLWH, employment was associated (p ≤ .05) with improved adherence to HIV care visits and HIV RNA viral suppression. Using multivariable regression modeling, differences were found between WLWH and women at risk for HIV. Among WLWH, household income, QOL, education, and time providing childcare remained associated with employment in adjusted multivariable analyses (R2 = .272, p < .001). A better understanding of the psychosocial and structural factors affecting employment is needed to reduce occupational disparities among WLWH.

Driving habits, cognition, and health-related quality of life in middle-aged and older adults with HIV

Cognitive impairment is known to increase with aging in people living with HIV (PLWH). Impairment in cognitive domains required for safe driving may put PLWH at risk for poor driving outcomes, decreased mobility, and health-related quality of life (HRQoL). This study described the driving behaviors of middle-aged and older PLWH and examined correlations between driving behaviors and cognitive functioning (Aim 1), and driving behaviors and HRQoL domains (Aim 2). A sample of 260 PLWH ages 40 and older completed a comprehensive assessment including a battery of cognitive tests, an HRQoL measure, and a measure of self-reported driving habits. Associations between driving habits, cognitive function, and HRQoL domains were examined. While 212 (81.54%) participants reported currently driving, only 166 (63.85%) possessed a driver's license. Several significant correlations emerged between driving habits and both cognitive and HRQoL variables, with a general pattern suggesting that current greater driving exposure was associated with better cognitive functioning and HRQoL. Given consistent associations that emerged between the social functioning HRQoL domain and several driving habits, multivariable regression was conducted to examine the unique association between an index of greater driving exposure (i.e., days driven per week) and social functioning, adjusting for potential confounders (race, income, education, depression, and global cognition). Results showed that more days driven per week was a significant, independent correlate of higher social functioning. Understanding the factors underlying driving behaviors in PLWH may contribute to interventions to promote better mobility and improved access to care.

Comparison of counseling methods to promote employment for HIV+ ADULTS

BACKGROUND

Despite improved health and during a strong job market (pre-COVID-19), a substantial proportion of HIV+ adults remained unemployed. This study sought to provide time-limited counseling to promote employment goals.

OBJECTIVE

To determine whether behavioral activation (BA) or supportive counseling (SC), would be more effective in promoting vocational goals (full or part-time, paid or volunteer).

METHODS

The study included two groups: those with clinically significant fatigue, who were first treated with armodafinil. Once their fatigue diminished, they were enrolled in the counseling program. Those without fatigue were enrolled directly. Both BA and SC interventions were manualized, consisting of eight individual sessions plus a follow-up.

RESULTS

116 participants entered counseling, including 87 assigned to BA and 29 to SC. Of these, 79 completed counseling or found a job by session eight. By follow-up, 51%of BA versus 41%of SC participants had found jobs, a non-significant difference either clinically or statistically.

CONCLUSIONS

Multiple issues contributed to difficulty in employment, including gaps in resumes, loss of contact with former colleagues, and uncertainty about career direction. Ongoing barriers included substance use, housing instability, ambivalence about forfeiting government benefits, as well as inadequately treated depression. Success in employment for about half of participants is, in this context, a reasonable outcome.

The Impact of HIV-Associated Neurocognitive Impairment on Driving Performance in Commercial Truck Drivers

Driving ability can be diminished amongst people with HIV with associated neurocognitive impairment (NCI). We explore the relationship between HIV status, NCI and driving ability in professional truck drivers. Forty male professional drivers (20 HIV-positive; mean age = 39.20 ± 7.05) completed a neuropsychological test battery, two driving simulator tasks that assessed driving ability, and a driving history and habits questionnaire. A higher proportion of HIV-positive drivers exhibited impaired overall cognitive performance (p ≤ 0.001). Overall, drivers with NCI (defined as z ≤ 1.00) were more likely than those without NCI to crash (p = 0.002). There were no significant between-group (HIV-positive versus HIV-negative) differences with regard to self-reported on-road driving events. Professional drivers with NCI, as measured on a driving simulator, are at increased risk of making driving errors under high-risk conditions compared to their neurocognitively normal counterparts. These data should inform driver health management with regard to annual medical screening and surveillance.

Employment and Occupational Productivity Among Women Living With HIV: A Conceptual Framework

ABSTRACT

Women living with HIV (WLWH) have lower employment rates and more difficulty finding and keeping employment compared with their counterparts without HIV. These disparities affect physical, psychological, and socioeconomic outcomes, and they may compound the disadvantages associated with living with HIV. Although historical literature has emphasized the impact of clinical factors on employment, current evidence suggests that socioeconomic and psychosocial factors associated with HIV should be included for a more comprehensive view. Based on this broader inclusion, a conceptual framework is presented describing how socioeconomic and psychosocial characteristics influence employment acquisition and maintenance among WLWH. The framework posits that there is a reciprocal relationship between employment acquisition and occupational productivity, and psychological health, physical health, social support, and empowerment. Implications for future research and interventions include (a) an extended conceptualization of vocational rehabilitation and (b) the use of peer support groups to increase social capital, empowerment, knowledge, and resources among WLWH.

A supervised exercise intervention fails to improve subjective and objective sleep measures among older adults with and without HIV

BACKGROUND

Chronic sleep disruption can have significant negative health effects and prior studies suggest that people with HIV (PWH) have disproportionately higher rates of sleep problems.

METHODS

We evaluated baseline sleep of sedentary, older adults (50-75 years) with (n = 28) and without HIV (n = 29) recruited into a 24-week exercise study. Subjective sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI); objective sleep parameters were assessed using wrist-worn actigraphy. Regression models were used to investigate changes in outcomes.

RESULTS

Fifty-seven participants completed the intervention. At baseline, PWH had significantly lower sleep efficiency (88.7 [95% CI 86, 91]%) compared to controls (91.8 [95% CI 91, 93]%; p = 0.02); other sleep measures indicated poorer sleep among PWH but did not reach statistical significance (p ≥ 0.12). Overall, sleep outcomes did not significantly change with the exercise intervention (all p > 0.05). In adjusted analyses, PWH demonstrated a decrease in total sleep time (-22.1 [-43.7, -0.05] p = 0.045) and sleep efficiency (-1.3 [-2.5, -.01], p = 0.03) during the 24 weeks of exercise; these differences were attenuated and no longer significant after adjusting for exercise intensity. At the completion of the intervention, compared to controls, PWH had significantly poorer sleep by PSQI score (2.2 [0.6, 3.8]; p = 0.006) and sleep efficiency (-2.8 [-5.4,-0.2]%; p = 0.04).

CONCLUSIONS

In this study, sleep disturbance was more prevalent in sedentary older PWH compared to uninfected controls. An exercise intervention had minimal effect on sleep impairments among PWH nor controls. Among older adults, interventions beyond cardiovascular and resistance exercise may be needed to significantly alter subjective and objective sleep outcomes.

A Scoping Review of Employment and HIV

Employment is a social determinant of health that is important for understanding health behaviors, health outcomes and HIV transmission among people living with HIV. This study is a scoping review of the literature that addresses (a) the relationship between employment and the HIV continuum of care, (b) determinants of employment among PLWH and (c) experiences with employment. We searched two databases, PubMed and Embase, and identified a total of 5622 articles that were subjected to title and abstract review. Of these, 5387 were excluded, leaving 235 articles for full-text review. A total of 66 articles met inclusion criteria and were included in the study. The literature suggests that employment status is positively associated with HIV testing, linkage to HIV care, retention in HIV care, and HIV medication adherence. Guided by a social-ecological framework, we identified determinants of employment at the individual, interpersonal, organizational, community, and policy levels that are amenable to public health intervention. Experiences with employment, including barriers, facilitators, advantages, disadvantages, and needs, provide additional insight for future research and programs.

Cognitive Reserve Over the Lifespan: Neurocognitive Implications for Aging With HIV

Approximately 59% of adults living with HIV experience HIV-associated neurocognitive disorder, a collection of symptoms and cognitive deficits in various cognitive domains. As the HIV population ages, the prevalence and severity of such cognitive deficits are expected to grow. Understanding how these cognitive deficits manifest is important for nurses and health care providers. This article provides an overview of cognitive reserve and evidence of how it is compromised by HIV, aging, and individual characteristics. Within this context of cognitive reserve, the role of neuroinflammation, neurotoxicity, substance use, comorbidities, depression and anxiety, social isolation, and sedentary lifestyle is reviewed. From this, strategies used to address cognitive deficits are provided, including topics such as psychostimulants, cognitive training, multimodal lifestyle interventions, and compensation strategies. Scenarios of successful and unsuccessful cognitive aging are presented to provide a lifespan perspective of cognitive reserve. Implications for clinical practice and research are provided, as it relates to aging.

Returning to work after fatigue treatment and counseling in HIV/AIDS

BACKGROUND

Employment rates for people with HIV/AIDS are low, compared to the general population. One widespread barrier is fatigue, accompanied by daytime sleepiness and a lack of stamina. Previous pharmacological studies have demonstrated improvement of fatigue-related symptoms without affecting work-related goal attainmentOBJECTIVE:In this pilot study, we sought to determine whether a pharmacologic-behavioral two-phase combined approach could facilitate returning to work.

METHODS

HIV+ participants with fatigue were treated with armodafinil. If energy improved, 8 sessions of biweekly manualized Behavioral Activation (BA) counseling were added to medication maintenance. Outcome was assessed on a 3-point scale along with clinician and self-ratings.

RESULTS

Of the 46 participants enrolled in BA, 15 (33%) did not complete all 8 sessions: 6 got jobs so they no longer needed counseling; 4 did not like BA, and 5 dropped out for reasons such as moving away or substance use relapse. Of the 46, 29 (63%) attained their vocational goal and showed significant changes on self-report scales.

CONCLUSIONS

Our integrated treatment including armodafinil plus BA counseling significantly increased the success of achieving work-related goals. The two-phase medication plus counseling program was well-tolerated by participants and the manualized BA counseling was readily applied by counselors without advanced mental health training, making the method potentially feasible in community settings.

Stress and resilience among women living with HIV in Nigeria

Background

Psychological morbidities concurrent with HIV have been the focus of considerable scientific investigations. However, researchers have largely overlooked HIV-related stress and resilience among women living with HIV in rural communities.

Aim

This study explored the associations between psychological resilience and HIV-related stress among women living with HIV.

Setting

The study was conducted in three randomly selected hospitals that provide primary HIV care in Niger state, Nigeria.

Methods

A predictive cross-sectional design was used to describe the relationship between perceived stress and resilience among the study population.

Results

Out of 748 participants who completed the Connor–Davidson resilience scale and the perceived stress scale questionnaires, 676 returned the questionnaire in usable form. While the results showed moderate levels of perceived stress and a high level of psychological resilience, there was a significant and negative relationship between HIV-related stress and psychological resilience (r = -0.601, p = < 0.001). Also, higher resilience was significantly associated with decreased perceived stress.

Conclusion

It is concluded that measures to promote resilience and employment opportunity may ameliorate HIV-related stress among women living with HIV.

Differential effects of unemployment on depression in people living with HIV/AIDS: a quantile regression approach

Unemployment is associated with depression in people living with HIV (PLWH). However, few studies have examined the effects of unemployment on PLWH with different levels of depression. The current study explores the plausible differential effects of unemployment on the different percentiles of depression in PLWH employing a quantile regression (QR) approach, based on a recent survey of 411 PLWH in China. Among participants, 47.7% had elevated depressive symptoms, and 23.8% were unemployed. The effects of unemployment on depression were statistically significant with a trend of initial increase followed by a decline at the quantile levels of 0.51-0.90 of depression. The maximum effect of unemployment status on depression was statistically significant at the 70th and 75th percentiles of depression (coefficient = 7.0, p < .01). Tailored strategies and interventions should be implemented to address the differential needs of PLWH with various levels of depressive symptoms.

Frequency and Correlates of Subjective Cognitive Impairment in HIV Disease

The increasing prevalence of older adults living with HIV has raised growing concerns about a possible rise in the incidence of neurocognitive disorders due to HIV and other age-related factors. In typical aging, subjective cognitive impairment (SCI) among individuals with normal neurocognitive functioning may be an early manifestation of an incipient neurocognitive disorder. The current study examined the frequency and correlates of SCI in 188 HIV-infected adults without performance-based neurocognitive deficits or a current psychiatric disorder and 133 HIV seronegative comparison participants. All participants completed the Prospective and Retrospective Memory Questionnaire and Profile of Mood States Confusion/Bewilderment scale. Consistent with the diagnostic criteria proposed by Jessen et al. (Alzheimers Dement 10(6):844-852, 2014), participants were classified with SCI if their scores on either of the self-reported measures was greater than 1.5 SD above the normative mean. A logistic regression controlling for current mood complaints and lifetime history of substance use disorders revealed that HIV infection increased the odds of SCI (odds ratio= 4.5 [1.6, 15.4], p = 0.004). Among HIV+ individuals, SCI was associated with lower performance-based learning and delayed memory scores (Cohen's d range 0.41-0.42.) and poorer global everyday functioning (odds ratio= 8.5 [2.6, 15.9]), but not HIV disease severity (ps > 0.10). In a sample of individuals without neurocognitive impairment or elevated mood symptoms, HIV disease was associated with a nearly fivefold increased odds of SCI compared to seronegative individuals, which may indicate an increased risk for developing major neurocognitive disorders as these HIV+ individuals age.

Effects of speed of processing training and transcranial direct current stimulation on global sleep quality and speed of processing in older adults with and without HIV: A pilot study

Some older adults with human immunodeficiency virus (HIV) experience poor sleep which can worsen cognition. Transcranial direct current stimulation (tDCS) and cognitive training have improved sleep and cognition in studies of older adults; yet, their combined influence is unknown in adults with HIV. Older adults with HIV (n = 33) and without HIV (n = 33) were randomized to receive 10 one-hour sessions of speed of processing (SOP) training with tDCS or sham tDCS over approximately 5 weeks. tDCS with SOP training did not improve sleep. Omitting correction of multiple comparisons for this exploratory pilot study, main effects for HIV (F[1, 59] = 5.26, p = .03, η_p² = .082) and tDCS (F[1, 59] = 5.16, p = .03, η_p² = .080) on the Digit Copy Test were detected. A HIV × tDCS interaction was detected on the Letter Comparison Test (F[1, 59] = 5.50, p = .02, η_p² = .085). Useful Field of View scores improved across all four groups (F[1, 59] = 64.76, p < .001, η_p² = .523). No significant effects for HIV (F[1, 59] = 1.82, p = .18) and tDCS (F[1, 59] = .01, p = .94) were detected on the Useful Field of View test. While the current study did not show effects of combined tDCS and SOP training on sleep quality, future studies are needed to examine the effects of such interventions on sleep-related cognitive functions among cognitively impaired adults with HIV.

Revisiting Successful Aging With HIV Through a Revised Biopsychosocial Model: An Update of the Literature

The concept of successful aging was recognized only recently by HIV researchers because people living with HIV (PLWH) in the early epidemic were not expected to survive. With the introduction of antiretrovirals that block viral replication, PLWH are now aging with HIV. Given the complex nature of HIV within the social, economic, and political climates in which it occurs, a holistic model of successful aging is needed to guide researchers and clinicians. Several overarching models exist, but must be updated for rapidly advancing HIV and aging research agendas. We provide an updated, adapted, and integrated biopsychosocial model of successful aging with HIV based on the principles of Baltes and Baltes (1998) on 8 essential components of successful aging: (a) length of life, (b) biological health, (c) mental health, (d) cognitive efficiency, (e) social competence, (f) productivity, (g) personal control, and (h) life satisfaction. Clinical practice and research implications are highlighted.

The effects of aging and HIV disease on employment status and functioning

OBJECTIVE

As the prevalence of older adults living with HIV disease increases, questions are emerging regarding the extent to which older age amplifies the adverse effects of HIV on employment status and functioning. This cross-sectional study sought to (1) investigate the combined effects of HIV and older age on employment status, (2) identify clinicodemographic correlates of employment status among older HIV+ persons, and (3) examine the combined effects of HIV and age on workplace performance among employed participants.

METHOD

The sample was 358 HIV+ (163 older, 195 younger) and 193 HIV- (94 older, 99 younger) adults, who completed a comprehensive neurocognitive research assessment that included measures of employment status and current workplace functioning.

RESULTS

We observed main effects of HIV and age on employment status, but no interaction. The older HIV+ sample demonstrated particularly high rates of disability, rather than elective retirement or unemployment. Among older HIV+ adults significant predictors of employment status included age, global neurocognitive functioning, combination antiretroviral therapy status, age at HIV infection, and hepatitis C coinfection. Finally, self-reported work functioning of older HIV+ adults differed only from the younger HIV- group.

CONCLUSION

Findings suggest that older age and HIV disease have additive adverse effects on employment status, but not work functioning, and that employment status is associated with both neurocognitive and medical risk factors among older HIV+ adults. Further longitudinal research is needed to elucidate specific disease and demographic characteristics that may operate as protective factors for retaining gainful employment among older HIV+ adults.

Employment as a Social Determinant of Health: Exploring the Relationship Between Neurocognitive Function and Employment Status

Purpose:

To explore employment as a social determinant of health through examining the relationship between neurocognitive function and employment status.

Method:

The authors explored the causal relationship between employment status and neurocognitive function by conducting a systematic review of 15 longitudinal studies. The identified studies were conducted in Australia, Denmark, Norway, and the United States.

Results:

Five neurocognitive function domains were identified (i.e., complex attention, executive function, learning and memory, language, perceptual-motor function) across diagnosis (i.e., bipolar disorder, first-episode psychosis, human immunodeficiency virus, major depression, schizophrenia-spectrum disorders, traumatic brain injury). Unemployment was correlated with poorer attention, executive function, learning and memory, perceptual-motor function, and language. Employment was correlated with better attention, executive function, learning and memory, perceptual-motor function.

Conclusion:

The acknowledgment of the relationship between neurocognitive function and employment status can assist service providers in assessing and developing strategies to enhance and maintain employment outcomes. The assessment of neurocognitive function could be further explored by identifying standard measures and assessment timelines to assess the six domains across diagnosis. Vocational rehabilitation services could integrate cognitive interventions (cognitive rehabilitation, cognitive enhancement therapy, cognitive remediation) to explore the effect on neurocognitive function and employment outcomes. Further longitudinal research studies are needed, for both persons with disabilities and persons without disabilities, to elucidate the relationship between employment status and neurocognitive function.

Are people living with HIV less productive at work?

Health problems may cause decreased productivity among working people. It is unclear if this also applies for people living with HIV (PLWH). This cross-sectional study compares data of PLWH of one of the main HIV treatment centres in the Netherlands (n = 298) to data of the general working population from a previously conducted study (n = 986). We investigate whether productivity at work differs between these groups. The questionnaires used in these studies contained a core of identical questions regarding productivity losses, in the form of absenteeism and presenteeism, over a four-week period and a variety of baseline characteristics, including health status measured with EQ-5D. For PLWH additional clinical data were collected from patient records. From the data, descriptive statistics were computed to characterize the samples. Pearson correlations were used to explore significant associations of productivity with baseline characteristics. A two-part model was used to evaluate both the occurrence and of size of productivity losses in working PLWH and an aggregated sample of PLWH and the general population. It was observed that, on average, total productivity losses do not differ significantly between working PWLH and the general working population, but that the occurrence and size of absenteeism and presenteeism were different. Furthermore, more health problems were associated with higher productivity losses. HIV status was not significantly associated with productivity losses. We conclude that among working people, health status was related to productivity losses but HIV status was not. However, further research is needed into the relation between HIV status and unemployment.

Aging and Neurocognitive Functioning in HIV-Infected Women: a Review of the Literature Involving the Women's Interagency HIV Study

HIV-infected women may be particularly vulnerable to certain types of neurocognitive impairments which may be exacerbated by aging and other predictors. Within the context of cognitive reserve, this article examines issues surrounding women as they age with HIV. For this, a review of 12 recent studies (2013-2016) using data from the Women's Interagency HIV Study (WIHS), the largest cohort study comparing HIV-infected and demographically matched uninfected women, is presented that specifically examines neurocognition. In general, HIV-infected women are more vulnerable to developing neurocognitive impairments than uninfected women; other factors that may contribute to these neurocognitive impairments include recent illicit drug use, reading level (educational quality/cognitive reserve), stress, PTSD, insulin resistance, liver fibrosis, and age. Surprisingly, when examined in some analyses, age × HIV interactions were not observed to impact neurocognitive performance, findings largely consistent in the literature; however, longitudinal analyses of these data have yet to be performed which may yield future insights of how cognitive reserve may be compromised over time. Yet, with insulin resistance, liver fibrosis, stress, and other known predictors of poorer neurocognition also occurring more with advanced age, in time, the synergistic effect of age and HIV may be more robust and observable as this population ages.

Feasibility and Acceptability of Ecological Momentary Assessment of Daily Functioning Among Older Adults with HIV

OBJECTIVE

This study aimed to examine the feasibility, acceptability, and initial validity of using smartphone-based ecological momentary assessment (EMA) to assess daily functioning and other behavioral factors among older HIV+ adults.

METHODS

Twenty older HIV+ adults (mean age: 59 years) completed laboratory-based neurobehavioral and functional assessments then completed EMA surveys via smartphones five times per day for one week.

RESULTS

Excellent EMA adherence (86.4%) was found, and participants rated their experience with EMA methods positively. Time-use data indicated participants were spending 74% of their waking-sampled time at home, 63% of their time alone, and 32% of their time engaged in passive leisure activities (e.g., watching TV). Better neurocognitive and functional capacity abilities were correlated with less time spent in passive leisure activities. Lastly, mood and cognitive symptom data collected via EMA were significantly associated with scores from laboratory-based assessments of these same constructs.

CONCLUSIONS

EMA via smartphones is a feasible and acceptable data collection method among older HIV+ adults and appears to be a promising mobile tool to assess daily functioning behaviors in HIV. These preliminary findings indicate older HIV+ adults are spending a considerable amount of time at home, alone, and engaged in passive leisure activities, primarily watching TV. EMA may contribute to future research examining functional disability among the growing population of older HIV+ adults.

Physical Activity and Cognitive Function in Older Adults: The Mediating Effect of Depressive Symptoms

Depressive symptoms and social networks may influence the relationship between physical activity and cognition. Using structural equation modeling, depressive symptoms and social networks were examined as mediators between physical activity and cognition in community-dwelling older adults (N = 122), with a range of cognitive abilities (e.g., normal, mild cognitive impairment). The model included age, physical activity, sedentary behavior, sleeping, social networks, depressive symptoms, and cognitive function. A path was observed between physical activity, depressive symptoms, and cognition; specifically, those who were more physically active experienced less depression and better cognitive functioning. No relationship between social networks and cognition was found. This model fits the data well (goodness-of-fit index = .93, adjusted goodness-of-fit index = .90, root mean square error of approximation = .06). Results suggest that physical activity may mitigate depressive symptoms, with beneficial effects on cognitive functioning in both those with and without mild cognitive impairment. Suggestions for managing depression and improving cognitive functioning are provided.

Feedback on a Multimodal Cognitive Intervention for Adults Aging With HIV: A Focus Group Study

Nearly 50% of adult persons living with HIV (PLWH) experience HIV-associated neurocognitive disorder (HAND), which is associated with deteriorating brain health and cognitive functioning. Multimodal interventions that simultaneously improve physical activity, nutrition, and sleep hygiene may be of value for adult PLWH, especially as they age and become vulnerable to HAND. We used four focus groups of PLWH (N = 30; ages ≥ 50 years) to solicit feedback about Cognitive Prescriptions, a multimodal cognitive intervention. Lifestyle and health behaviors pertaining to Cognitive Prescriptions were assessed, including: (a) physical activity, (b) mental activity, (c) nutrition, (d) social engagement, (e) emotional health, (f) sleep hygiene, and (g) substance use. When presented a template of the intervention, participants expressed favorable opinions and remarked they would want to work with a clinician, paraprofessional, or peer to implement such a program into their own daily routines. From this, implications for practice and research are provided.

Self-reported adherence to oral cancer therapy: relationships with symptom distress, depression, and personal characteristics

BACKGROUND

Therapeutic cancer chemotherapy is most successful when complete dosing is achieved. Because many newer therapeutic agents are oral and self-administered by the patient, adherence is a concern. The purpose of our analysis was to explore relationships between adherence, patient characteristics, and barriers to adherence.

METHODS

This secondary analysis utilized self-reported data from a randomized trial of self-care management conducted at two cancer centers in the US. Symptom distress was measured using the 15-item Symptom Distress Scale (SDS-15) and depression with the Patient Health Questionnaire-9 (PHQ-9). Adherence to oral medication was self-reported using the 8-item Morisky Medication Adherence Scale (MMAS-8). Measures were collected via Web-based, study-specific software ~8 weeks after treatment start date. Odds of low/medium adherence (score <8) were explored using univariate logistic regression. Given the number of factors and possible relationships among factors, a classification tree was built in lieu of a multivariable logistic regression model.

RESULTS

Of the eligible participants enrolled, 77 were on oral therapy and 70 had an MMAS score. Forty-nine (70%) reported a high adherence score (=8). Higher odds of low/medium adherence were associated with greater symptom distress (P=0.09), more depression (P=0.05), chemotherapy vs hormonal oral medication (P=0.03), being female (P=0.02), and being randomized to the control group in the parent trial (P=0.09). Conversely, high adherence was associated with working (P=0.08), being married/partnered (P=0.004), and being older (P=0.02). Factors identified as significantly related to low/medium adherence from the univariate logistic regression analyses were supported by the classification tree results.

CONCLUSION

Nonadherence to therapeutic oral medications in patients with cancer was associated with being unmarried/unpartnered, symptom distress, younger age, not working, and female sex. These findings may help to identify patients at risk for nonadherence and for whom supportive interventions to enhance adherence may be needed.
