Does cognitive intra-individual variability predict change in everyday functioning performance in women with and without HIV in the Women's Interagency HIV Study?

This study examined the association between cognitive intra-individual variability (IIV), a non-mean-based indicator of underlying neuropathology, and self-reported everyday functioning of 1,086 women with HIV (WWH) and 494 socio-demographically similar women without HIV (WWoH). Objective cognitive performance across seven domains and the self-rated Lawton & Brody scale of Instrumental Activities of Daily Living (IADL) were assessed among participants of the Women's Interagency HIV Study. Two types of cognitive IIV were calculated by taking the standard deviation across seven cognitive domains to calculate dispersion: 1) intra-individual standard deviation (denoted as IIV) and 2) coefficient of variation (denoted as IIV).

Patient activation and medication adherence in adults.

Background: Patients' level of medication adherence provides conflicting results in its relationship to patient activation. Multiple factors may be contributing to these mixed results.

Objectives: The primary purpose was to assess the association of patient activation to medication adherence in adults with chronic health conditions and low health literacy (HL).

An Automated Virtual Reality Program Accurately Diagnoses HIV-Associated Neurocognitive Disorders in Older People With HIV.

Background: HIV-associated neurocognitive disorders (HANDs) remain prevalent despite antiretroviral therapy, particularly among older people with HIV (PWH). However, the diagnosis of HAND is labor intensive and requires expertise to administer neuropsychological tests. Our prior pilot work established the feasibility and accuracy of a computerized self-administered virtual reality program (DETECT; Display Enhanced Testing for Cognitive Impairment and Traumatic Brain Injury) to measure cognition in younger PWH.

Mild Cognitive Impairment, But Not HIV Status, is Related to Reduced Awareness of Level of Cognitive Performance Among Older Adults.

Objective: Self-assessment of cognitive abilities can be an important predictor of clinical outcomes. This study examined impairments in self-assessments of cognitive performance, assessed with traditional neuropsychological assessments and novel virtual reality tests among older persons with and without human immunodeficiency virus (HIV) and mild cognitive impairment (MCI).

Methods: One hundred twenty-two participants (82 persons with HIV; 79 MCI+) completed a traditional neuropsychological battery, DETECT virtual reality cognitive battery, and self-reported their general cognitive complaints, depressive symptoms, and perceptions of DETECT performance.

Cogstim: A Shared Decision-making Model to Support Older Adults' Brain Health.

The lack of effective treatments for cognitive decline in older adults has led to an interest in the possibility that lifestyle interventions can help to prevent changes in mental functioning and reduce the risk for dementia. Multiple lifestyle factors have been related to risk for decline, and multicomponent intervention studies suggest that changing older adults' behaviors can have a positive impact on their cognition. How to translate these findings into a practical model for clinical use with older adults, however, is not clear.

e-Health Literacy Scale, Patient Attitudes, Medication Adherence, and Internal Locus of Control.

Background: Health literacy is related to a variety of health outcomes, including disease control, health-related quality of life, and risk for death. Few studies have investigated the relation of electronic health literacy (e-health literacy) to outcomes or the mechanism by which they may be related.

Methods: Secondary data were drawn from participants in a larger study on chronic disease self-management who were age 40 years and older, had at least one chronic health condition and a health literacy score of 8th grade or below on the validated short form of the Rapid Estimate of Adult Literacy in Medicine.

A mobile app for chronic disease self-management for individuals with low health literacy: A multisite randomized controlled clinical trial.

Objective: The purpose of this study was to evaluate the effects of a mobile app designed to improve chronic disease self-management in older adult patients with low health literacy and who had at least one chronic health condition, and to assess the impact of delivering information at different levels of reading difficulty.

Methods: A randomized controlled trial was completed at two sites. Individuals 40 years of age and older screened for low health literacy who had at least one chronic health condition were randomly assigned to a tailored information multimedia app with text at one of three grade levels.

Creating a Tailored Info App to Promote Self-Management Skills in Persons with Chronic Health Conditions: Development Strategies and User Experience.

Persons with chronic health conditions, such as heart disease, diabetes, hypertension, and others, often experience self-management problems that are not disease specific. These include disrupted sleep, pain, memory issues, and challenges in working with healthcare providers. These patients may benefit from information and skill development for these problems, but simply providing them information in brief sessions during clinical appointments or in handouts or pamphlets may not have a substantial impact on their behavior.

Training Clinical Researchers with Design Thinking to To Develop Dementia Caregiving Research Initiatives.

Training healthcare professionals with Design Thinking (DT) can support patient-centred care by recognizing patient/care provider needs through empathizing. This article explored the Design Thinking in improving clinical researchers' understanding of relatively unexplored and understudied dementia caregiving problems. Following the Double-Diamond, a Design Thinking process model, we conducted a series of workshops and invited family caregivers of patients with dementia as active participants to provide training to clinical researchers on Design Thinking.

Durable viral suppression among persons with HIV in the deep south: an observational study.

This study assessed predictors of stable HIV viral suppression in a racially diverse sample of persons living with HIV (PWH) in the southern US. A total of 700 PWH were recruited from one of four HIV clinics in Metro Atlanta, GA. Data were collected from September 2012 to July 2017, and HIV viral loads were retrieved from EMR for 18 months.

Loneliness Mediates the Effect of HIV-related Stigma on Depressive Symptoms among Older Persons Living with HIV.

Studies have shown associations among stigma, loneliness, and depressive symptoms in older persons living with HIV (PWH) but research assessing the mediating pathway among these variables is sparse. Building on this prior work, the aim of this study was to test the mediating effects of loneliness. A sample of 146 older PWH (≥50 years old) from an outpatient HIV clinic in Atlanta, GA, completed a cross-sectional survey.

Social network size and its relationship to domains of quality-of-life among older persons living with HIV.

Gerontological research suggests that social network characteristics are key elements of successful aging as they are related to a positive quality-of-life (QoL). Less is known about the social networks of persons aging with HIV. To describe social network characteristics and assess the effect of social network size on QoL, a sample of 146 OPWH (age ≥50) was recruited from an outpatient HIV clinic in Atlanta, GA.

Barriers to Pain Management: Incongruence in Black Cancer Caregiving Dyads.

Context: To effectively manage cancer pain, there is a need to understand how caregiving dyads appraise symptoms. Dyadic appraisal of symptoms influences whether the dyad perceives the patient's pain is managed well and whether they are on the same page with their appraisal. Beliefs can act as barriers to the dyadic appraisal.

Congruence of pain perceptions between Black cancer patients and their family caregivers.

Purpose: This cross-sectional study evaluated congruence in pain assessment among Black cancer patients taking opioids for pain and their family caregivers and the effects of patient-reported depressive symptoms and cognitive complaints on the congruence.

Methods: Patient-reported pain scores (current, average, and worst pain severity and pain interference) and caregiver proxy scores were independently assessed (Brief Pain Inventory). Patient-reported depressive symptoms (Patient Health Questionnaire-8) and cognitive complaints (Cognitive Difficulties Scale) were also assessed.

A Preliminary Test of an mHealth Facilitated Health Coaching Intervention to Improve Medication Adherence among Persons Living with HIV.

This study examined feasibility, acceptability, and preliminary efficacy of an mHealth facilitated health coaching antiretroviral therapy (ART) adherence intervention. Persons living with HIV (n = 53) were randomized to an in-person adherence session and 12 months of app access and health coaching via the app (Fitbit Plus) versus single adherence session (SOC). At baseline and 1, 3, 6, and 12 months, we measured ART adherence, substance use, and depressive symptoms.

Patterns and Predictors of Cognitive Function Among Virally Suppressed Women With HIV.

Cognitive impairment remains frequent and heterogeneous in presentation and severity among virally suppressed (VS) women with HIV (WWH). We identified cognitive profiles among 929 VS-WWH and 717 HIV-uninfected women from 11 Women's Interagency HIV Study sites at their first neuropsychological (NP) test battery completion comprised of: Hopkins Verbal Learning Test-Revised, Trail Making, Symbol Digit Modalities, Grooved Pegboard, Stroop, Letter/Animal Fluency, and Letter-Number Sequencing. Using 17 NP performance metrics (T-scores), we used Kohonen self-organizing maps to identify patterns of high-dimensional data by mapping participants to similar nodes based on T-scores and clustering those nodes.

The Intersection of Cognitive Ability and HIV: A Review of the State of the Nursing Science.

Neurocognitive problems have been endemic to the HIV epidemic since its beginning. Four decades later, these problems persist, but currently, they are attributed to HIV-induced inflammation, the long-term effects of combination antiretroviral therapy, lifestyle (i.e.

Cognitive changes during the menopausal transition: a longitudinal study in women with and without HIV.

Objective: To assess longitudinal changes in cognitive performance across menopause stages in a sample comprised primarily of low-income women of color, including women with HIV (WWH).

Methods: A total of 443 women (291 WWH; 69% African American; 18% Hispanic; median age = 42 y) from the Women's Interagency HIV Study completed tests of verbal learning and memory, attention/working memory, processing speed, verbal fluency, motor skills, and executive function first at an index premenopausal visit and thereafter once every 2 years for up to six visits (mean follow-up = 5.7 y).

Factors Predicting Detrimental Change in Declarative Memory Among Women With HIV: A Study of Heterogeneity in Cognition.

Objective: Statistical techniques used to study cognitive function in HIV typically yield normative estimates and can mask the heterogeneity in cognitive trajectories over time. We applied a novel statistical approach to identify clusters of individuals with distinct patterns of change in declarative memory in HIV-seropositive (HIV+) and HIV-seronegative (HIV-) women.

Methods: 1731 women from the Women's Interagency HIV Study, a multi-center, prospective cohort study, completed the Hopkins Verbal Learning Test-Revised (HLVT-R) at >2 visits.

Exercise and Cognitive Training Intervention Improves Self-Care, Quality of Life and Functional Capacity in Persons With Heart Failure.

This study evaluated a 12-week, home-based combined aerobic exercise (walking) and computerized cognitive training (EX/CCT) program on heart failure (HF) self-care behaviors (Self-care of HF Index [SCHFI]), disease specific quality of life (Kansas City Cardiomyopathy Questionnaire [KCCQ]), and functional capacity (6-minute walk distance) compared to exercise only (EX) or a usual care attention control (AC) stretching and flexibility program. Participants ( = 69) were older, predominately female (54%) and African American (55%). There was significant improvement in self-care management, (2, 13) = 5.

Serial position effects in HIV-infected injecting drug users.

This study examined memory and serial position effects in HIV-positive injecting drug users (IDUs), HIV-negative IDUs, and nondrug using control participants. Exploratory analyses investigating a possible mediating role of executive functions with HIV infection, drug use, and memory were also performed. Control participants showed stronger primacy effects than did both HIV-positive and HIV-negative IDUs and also outperformed the drug using groups on all memory measures.

HIV-1 infection and its impact on the HPA axis, cytokines, and cognition.

Immediately after infection, Human immunodeficiency virus, type 1 (HIV-1) enters the central nervous system (CNS) and is localized in highest concentration in the hippocampus and basal ganglia. Since these areas are associated with HPA axis and autonomic activities as well as cognition, it has been hypothesized that these functions will be impacted adversely in HIV-1 infection. In the treatment of HIV infection, although the highly potent antiretroviral (HAART) drugs have been effective in reducing peripheral viral load and prolonging life expectancy, these drugs do not cross the blood-brain barrier in therapeutic concentrations.

The HPA axis in HIV-1 infection.

Several lines of evidence suggest that neuroendocrine abnormalities in general and HPA axis activity in particular occur in both HIV-1 infection and individuals engaging in chronic drug use. For instance, our studies showing attenuated norepinephrine as well as ACTH and cortisol responses to a cold pressor challenge in asymptomatic HIV-1 persons support such a concept. Furthermore, our data on investigations on mirror-star tracing and speech challenges also support the finding that neuroendocrine responses are compromised in HIV-1 infection.
