RESUMEN

People with HIV now have increased longevity; however, their health-related quality of life (HRQoL) still lags significantly compared to people without HIV. Perceived stress negatively impacts HRQoL, whereas psychosocial resources are linked to better HRQoL. This longitudinal analysis aims to explore the buffering role of psychosocial resources on the relationship between HRQoL and perceived stress. Participants (N = 240) included 142 persons with HIV (PwH) and 98 without HIV, M(SD) = 50.9(8.1) years. Multilevel models over four study years examined longitudinal relationships between HRQoL (outcome) and perceived stress (predictor) and potential moderation by psychosocial resources (personal mastery, social support, and resilience) by HIV serostatus. Among PwH only, personal mastery (p = 0.001), social support (p = 0.015), and resilience (p = 0.029) were associated with an attenuated effect of perceived stress (less negative slopes) for physical HRQoL over time. Bolstering personal mastery, social support, and resilience may have relevance for improving physical well-being among PwH.

RESUMEN

Objective: To assess the frequency of suicidal ideation (SI) among individuals with chronic spinal cord injury (SCI) and to identify risk factors associated with SI. Design: Cross-sectional. Setting: Community setting. Participants: Two hundred and forty-six individuals with chronic SCI participating in the Spinal Cord Injury Model Systems at a Level 1 Trauma center. Interventions: Not applicable. Main Outcome Measure: SI, as assessed by question 9 of the Patient Health Questionnaire-9. Results: Twenty-seven (11.0%) participants endorsed SI; 6 (22.2%) of whom endorsed active SI with a plan of self-harm. Participants who endorsed SI had significantly higher depressive symptoms, lower resilience, and lower satisfaction with life (all Ps<.001). They also had lower perceived health (P<.001), Craig Handicap Assessment & Reporting Technique Short Form (CHART-SF) physical independence (P=.013), and Spinal Cord Injury - Functional Index with Assistive Technology domains of basic mobility (P=.003), self-care (P=.042), and fine motor skills (P=.035). However, participants who endorsed SI were not significantly different in re-hospitalization rates and in other domains of CHART-SF and SCI-AT. Logistic regression, with a forward selection procedure, was used to identify significant predictors of endorsing SI in the context of multiple associated variables. Depressive symptoms (odds ratio [OR]=1.18, P=.020), resilience (OR=0.85, P=.003), and physical independence (OR=0.98, P=.019) remained significant predictors of SI. Conclusion: Study findings suggest higher levels of SI among people with SCI, a substantial proportion of whom have active SI. Individuals with SCI who endorse SI have greater burden of poor physical and mental health, as well as poorer functional status and adaptation. Interventions targeting multiple dimensions of quality of life may help reduce risk of SI and suicide among individuals with SCI.

RESUMEN

OBJECTIVE: This study compared rates of suicide attempt (SA) and suicidal ideation (SI) during the first 5 years after traumatic brain injury (TBI) among veterans and service members (V/SMs) in the Veterans Affairs (VA) and the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR) Model Systems National Databases to each other and to non-veterans (non-Vs) in the NIDILRR database. SETTING: Twenty-one NIDILRR and 5 VA TBI Model Systems (TBIMS) inpatient rehabilitation facilities in the United States. PARTICIPANTS: Participants with TBI were discharged from rehabilitation alive, had a known military status recorded (either non-V or history of military service), and successful 1-, 2-, and/or 5-year follow-up interviews completed between 2009 and 2021. The year 1 cohort included 8737 unique participants (8347 with SA data and 3987 with SI data); the year 2 (7628 participants) and year 5 (4837 participants) cohorts both had similar demographic characteristics to the year 1 cohort. DESIGN: Longitudinal design with data collected across TBIMS centers at 1, 2, and 5 years post-injury. MAIN OUTCOMES AND MEASURES: History of SA in past year and SI in past 2 weeks assessed by the Patient Health Questionnaire-9 (PHQ-9). Patient demographics, injury characteristics, and rehabilitation outcomes were also assessed. RESULTS: Full sample rates of SA were 1.9%, 1.5%, and 1.6%, and rates of SI were 9.6%, 10.1%, and 8.7% (respectively at years 1, 2, and 5). There were significant differences among groups based on demographic, injury-related, mental/behavioral health, and functional outcome variables. Characteristics predicting SA/SI related to mental health history, substance use, younger age, lower functional independence, and greater levels of disability. CONCLUSIONS: Compared with participants with TBI in the NIDILRR system, higher rates of SI among V/SMs with TBI in the VA system appear associated with risk factors observed within this group, including mental/behavioral health characteristics and overall levels of disability.

RESUMEN

Black/African American communities continue to be disproportionately impacted by HIV with Black people with HIV (PWH) exhibiting poorer outcomes along the HIV treatment cascade. Psychosocial burden may, in part, explain these health disparities among PWH. We implemented a culturally adapted intervention [individualized Texting for Adherence Building (iTAB)] to improve ART adherence among 89 Black PWH in San Diego, CA. We aimed to (1) characterize psychosocial risk factors (depression, negative life events, discrimination, medical mistrust) hypothesized to be barriers to HIV outcomes among Black PWH and (2) determine if these factors influence intervention engagement, HIV outcomes, and self-reported physical and mental health. We identified three levels of psychosocial burden (low, moderate, high) through hierarchical cluster analysis. Participants in the high burden cluster (n = 25) experienced the highest levels of depression, negative life events, and discrimination, in addition to the poorest intervention outcomes, HIV outcomes, and physical and mental health compared to low and moderate burden clusters. Participants in the low (n = 29) burden cluster had less medical mistrust than the moderate (n = 34) and high burden clusters, but low and moderate clusters did not differ on any outcomes. Overall, self-reported ART adherence was 83%, which is above estimates of ART adherence in the Western region of the United States. The iTAB intervention shows promise in improving HIV-related outcomes among Black PWH with low to moderate psychosocial burden; however, additional supports may need to be identified for those with high psychosocial burden.

RESUMEN

OBJECTIVE: To identify profiles of acute traumatic brain injury (TBI) severity and relate profiles to functional and well-being outcomes. SETTING: Acute inpatient rehabilitation and general community settings. PARTICIPANTS: Three hundred and seventy-nine individuals with moderate-severe TBI participating in the Traumatic Brain Injury Model Systems. DESIGN: Longitudinal observational study. MAIN MEASURES: At discharge-length of stay, Functional Independence Measure (FIM), and Disability Rating Scale (DRS). One-year post-injury-Glasgow Outcome Scale-Extended (GOS-E), FIM, and Satisfaction with Life Scale (SWLS). RESULTS: Latent profile analysis (LPA) was used to identify subgroups with similar patterns across 12 indicators of acute injury severity, including duration of posttraumatic amnesia, Glasgow Coma Scale, time to follow commands, and head CT variables. LPA identified 4 latent classes, least to most severe TBI (Class 1: n = 75, 20.3%; Class 2: n = 124, 33.5%; Class 3: n = 144, 38.9%; Class 4: n = 27, 7.3%); younger age, lower education, rural residence, injury in motor vehicle accidents, and earlier injury years were associated with worse acute severity. Latent classes were related to outcomes. Compared with Class 1, hospital stays were longer, FIM scores lower, and DRS scores larger at discharge among individuals in Class 3 and Class 4 (all P s < .01). One-year post-injury, GOS-E and FIM scores were significantly lower among individuals in Class 3 and Class 4 than those in Class 1 ( P s < .01). SWLS scores were lower only among individuals in Class 3 ( P = .036) compared with Class 1; other comparisons relative to Class 1 were not significant. CONCLUSIONS: Meaningful profiles of TBI severity can be identified from acute injury characteristics and may suggest etiologies, like injury in motor vehicle accidents, and premorbid characteristics, including younger age, rural residence, and lower education, that heighten risk for worse injuries. Improving classification may help focus on those at elevated risk for severe injury and inform clinical management and prognosis.

RESUMEN

OBJECTIVES: Quality of life (QoL) is an important consideration for people living with HIV (PWH). We investigated the relationship between stress, psychological resources, and proactive behaviors, on QoL (conceptualized as life satisfaction, successful aging, and depressive symptoms) by testing the hypotheses: (1) greater life stress (stress and functional impairment) is associated with poorer QoL; (2) resources (mastery, resilience, and social support) are associated with better QoL, beyond the influence of stress; and (3) proactive behaviors (medication management and leisure activities) mediate the relationship between resources and QoL. METHODS: Secondary analyses were performed (N = 128 PWH). Participants' mean age was 52.3, 83.6% were male, and 53.9 identified as white. Multivariate regressions were performed within the context of path analyses. RESULTS: In series 1, greater stress was associated with poorer life satisfaction (p < 0.001), lower self-rated successful aging (p < 0.001), and greater depression (p < 0.001). Functional impairment was associated with lower successful aging (p = 0.017) and greater depression (p = 0.001). In series 2, which accounted for mastery, resilience, social support, as well as demographic covariates, mastery was associated with greater life satisfaction (p = 0.038). In series 3, stress, functional impairment, leisure activities, and ART management were added to the model and social support was associated with engagement in leisure activities (p < 0.001), which was associated with better successful aging (p = 0.006). Fit indices suggested adequate relative fit. In bootstrapped analyses of indirect effects, social support was indirectly associated with successful aging through leisure activities (p = 0.020). CONCLUSIONS: QoL, as captured by self-rated successful aging, is threatened by stress but positively influenced by social support and engaging in leisure activities. Findings support a model of proactive successful aging for PWH.

RESUMEN

Background: A substantial proportion of individuals with spinal cord injury (SCI) experience depression, which has been negatively associated with recovery and community participation after injury. Despite significant barriers to seeking and receiving in-person mental health care, little research has focused on the efficacy of telepsychology among individuals with SCI. Objectives: To describe the design and implementation of an ongoing single-center, randomized controlled, video-based cognitive behavioral therapy (CBT) intervention among individuals with SCI. Methods: Participants within 1 year of SCI will be randomized 1:1 to intervention or usual care in a 24-week study. Intervention participants will engage in 10 sessions of CBT over 12 weeks with a licensed clinical psychologist, using iPads via Apple FaceTime. Primary outcomes are depressive symptomatology, anxiety, and life satisfaction (as measured by the Patient Health Questionnaire-9, Generalized Anxiety Disorder-7 and Satisfaction with Life Scale, respectively) measured at three time points (baseline, 12 weeks, and 24 weeks). These and other measures are also assessed during monthly telephone surveys conducted between primary timepoints. Results: Recruitment is ongoing. Forty-six participants have been enrolled thus far. Conclusion: Telepsychology is a convenient, flexible, and effective alternative to traditional in-person services. We anticipate that intervention participants will experience improvements in depressive and anxiety symptoms and will have greater life satisfaction. Telepsychology interventions among individuals with SCI are tasked to maintain participant privacy, provide assistive technology and/or engage caregivers to minimize mobility limitations, and manage risk remotely. Challenges encountered include recruitment during the COVID-19 pandemic. Early intervention on symptoms of psychological morbidity using telepsychology may facilitate greater adaptation following SCI.

RESUMEN

STUDY DESIGN: Uncontrolled clinical pilot study. OBJECTIVES: To assess usage, perceived impact, and satisfaction with a telemedicine program among individuals with spinal cord injury (tele-SCI). SETTING: Community-based. METHODS: Participants (N = 83) were recruited from acute SCI inpatient rehabilitation and outpatient SCI care at a community hospital to participate in a 6-month tele-SCI intervention administered by SCI subspecialty board-certified physiatrists via iPad FaceTime. In addition to monthly follow up interview calls, psychosocial and Quality of Life (QoL) measures were collected at baseline and post-intervention. A program satisfaction survey was also collected post-intervention. RESULTS: Seventy-five percent of participants engaged in tele-SCI visits (Median [IQR]: 2.5 [2.0, 4.0]) for a total of 198 tele-SCI visits. Bladder and bowel concerns were the leading topics discussed during tele-SCI visits, followed by neurological, pain, and functional concerns. Tele-SCI users resided further away (Median miles [IQR] - 114[73-177] vs. 81[46-116], p = 0.023) and reported seeking more clinical advice (Median [IQR] - 1.5[0-4.0] vs. 0[0-1.0], p = 0.002) compared to non-tele-SCI users. All other clinical utilization, baseline characteristics, psychosocial measures, and QoL did not differ among those who used tele-SCI and those who did not. The satisfaction survey suggested satisfaction with the tele-SCI intervention (89%), study equipment (89%), staff responsiveness (100%), and improved motivation for self-monitoring of health (71%). CONCLUSION: Study findings suggest that tele-SCI is a feasible modality for providing general SCI care. Further research is required to examine longer-term efficacy of remotely-provided care among individuals living with SCI.

RESUMEN

OBJECTIVE: To provide a systematic review of published interventions for posttraumatic brain injury fatigue (PTBIF). METHODS: PubMed and OneSearch were systematically searched for PTBIF interventions published between January 1, 1989, and March 31, 2019. Search results were evaluated for inclusion based on an abstract and full-text review. Inclusion criteria were (1) an investigation of an intervention, (2) participant sample including individuals with traumatic brain injury (TBI), (3) report of fatigue outcome data among individuals with TBI, and (4) articles available in English, Spanish, French, German, Afrikaans, or Dutch. A risk of bias assessment was conducted on all included publications. RESULTS: The search resulted in 2343 publications, with 37 meeting inclusion criteria for this review. Categories of PTBIF interventions were pharmacological ( n = 13), psychological ( n = 9), exercise-based ( n = 4), complementary alternative medicine ( n = 5), electrotherapeutic ( n = 3), and multimodal ( n = 3). Only methylphenidate, modafinil, and cognitive behavioral therapy interventions included multiple cohorts. Pharmacological and psychological interventions represented the groups with the lowest risk of bias. CONCLUSIONS: This review includes 37 studies, with 21 studies published after 2014. Methylphenidate and melatonin were the only pharmacological agents found to reduce fatigue in randomized controlled trials. Creatine given to children prospectively at onset of injury reduced fatigue at follow-up. Walking and water aerobics were effective exercise interventions in isolated randomized controlled studies. One multimodal study of children after concussion was more effective at reducing fatigue and postconcussion symptoms than community standard of care. Other interventions had equivocal results. Overall, more work remains to understand and develop treatments for PTBIF.

RESUMEN

BACKGROUND: Prior to implementing a pre-exposure prophylaxis (PrEP) demonstration study, we sought to explore cisgender women's experiences with HIV prevention, PrEP knowledge and attitudes, and anticipated barriers and facilitators for PrEP uptake and adherence in Southern California. METHODS: Three focus groups were held with cisgender women of mixed HIV serostatus in San Diego and Los Angeles between November 2015 and January 2016. Women were recruited through local testing sites, community-based organizations, and social media. Focus groups were audio-recorded and transcripts were analyzed using thematic analysis. RESULTS: Twenty-two women participated in focus groups, with median age 44 (IQR 30-53) and 6 identifying as non-Hispanic Black, 7 non-Hispanic White, 8 Latina and 1 mixed race. Despite limited prior PrEP knowledge and no PrEP experience, participants expressed interest in taking PrEP. Anticipated benefits were freedom from worry about HIV and control over sexual health; however, these were tempered by concerns including the possibility of increased HIV risk behaviors and potential side effects. Cisgender women reported potential barriers to PrEP uptake and adherence barriers, like competing priorities and poor PrEP access. Conversely, PrEP facilitators included utilizing practical tools such as phone apps and pill boxes as well as receiving encouragement from loved ones and support from other cisgender women on PrEP, women living with HIV and their medical providers. CONCLUSIONS: Although PrEP awareness was low, participants recognized the importance of PrEP and ways to facilitate adherence. Exploring perspectives of cisgender women is integral to developing effective interventions to support PrEP uptake and adherence for women at elevated risk for HIV.

RESUMEN

OBJECTIVE: Neurocognitive performance among older persons, including those living with HIV (people living with HIV [PLWH]), exhibits significant heterogeneity, suggesting subpopulations with differing profiles of neurocognitive impairment (NCI). Metabolic factors are associated with NCI, but their relationships to cluster-derived NCI profiles are unknown. METHOD: Participants (144 PLWH and 102 HIV uninfected) aged 50+ years completed a neuropsychological battery assessing seven cognitive domains. Latent class analysis (LCA) identified NCI profiles separately by HIV serostatus and in a combined sample. Obtained classes were examined against the Montreal Cognitive Assessment (MoCA) and diagnoses of HIV-associated neurocognitive disorders (HAND). Multinomial regression identified metabolic predictors of classification. RESULTS: LCA identified three latent classes in each participant sample: Class1Multidomain NCI (high probability of impairment across multiple domains), Class 2Learning & Recall NCI (high probability of impairment in learning and recall), and Class 3NC Unimpaired (low probability of NCI across all domains). Severity of NCI implied by classes corresponded with MoCA scores and HAND diagnoses. In analyses on the combined sample, compared to HIV-uninfected individuals, PLWH were more likely to be in Class1Multidomain NCI. Among PLWH, those with dyslipidemia and hypertension had greater odds of classification in Class 1Multidomain NCI while those with central obesity had higher odds of classification in Class 2Learning & Recall NCI; metabolic syndrome approached significance as a differential predictor. Regardless of HIV status, individuals with diabetes were more likely to be in Class 1Multidomain NCI. CONCLUSIONS: Metabolic risk factors confer heightened risk of NCI in HIV infection. Interventions to reduce metabolic risk may improve neurocognitive outcomes among PLWH.

RESUMEN

OBJECTIVES: To examine predictors of profiles of cognitive functioning among individuals receiving acute inpatient spinal cord injury (SCI) rehabilitation, as well as associations between their cognitive functioning and psychological well-being (life satisfaction and depression) 6 months after the baseline assessment. DESIGN: Prospective observational study design, with 2 assessments approximately 6 months apart. SETTING: A rehabilitation unit at a level 1 trauma hospital during acute SCI hospitalization and outpatient setting after discharge. PARTICIPANTS: Individuals (N=89) with SCI. INTERVENTION: None. MAIN OUTCOME MEASURES: Cognitive functioning (assessed by the Repeatable Battery for the Assessment of Neuropsychological Status), life satisfaction (measured by the Life Satisfaction Index A), and depressive symptoms (measured by the Patient Health Questionnaire-9). RESULTS: Latent profile analysis identified 3 classes of individuals with similar patterns of cognitive functioning: class1 (average levels of cognitive performance across all assessed domains; n=48), class 2 (average cognitive performance, except in recall and memory; n=23), and class 3 (low cognitive functioning across multiple domains of cognition; n=18). Fewer years of education, history of smoking, history of substance use other than alcohol, and greater postconcussion symptoms were associated with higher odds of classification in class 3 (P<.05). Six months post baseline, individuals in class 3 reported significantly lower levels of life satisfaction than individuals in class 1 (χ2(1)=5.86; P=.045) and marginally higher depressive symptoms than individuals in class 2 (χ2(1)=5.48; P=.057). CONCLUSIONS: The impact of impaired cognition during acute rehabilitation may persist after discharge and influence the psychological well-being of individuals with SCI. Identifying individuals with cognitive dysfunction and attending to modifiable risk factors and may help ameliorate maladjustment after SCI.

RESUMEN

Despite advancements in antiretroviral therapy, mild cognitive deficits persist in nearly half of people with HIV (PWH). The profile of impairment in HIV is highly variable with deficits observed in a range of cognitive domains. Despite evidence of greater cognitive impairment among women with HIV (WWH) vs. men with HIV (MWH), it is unclear how MWH and WWH differ in the type of cognitive impairment and in risk factors associated with cognitive impairment profiles. In a large and well-characterized sample of PWH, we used machine learning to identify profiles of cognitive functioning and their associated factors overall and within sex. Participants included 1,666 PWH (201 WWH; 1,465 MMH) from the HIV Neurobehavioral Research Program who completed a neuropsychological test battery at their baseline visits. Using demographically-adjusted T-scores from 13 test outcomes assessing motor skills, executive functioning, attention/working memory, episodic learning and memory, verbal fluency, and processing speed, we used Kohonen self-organizing maps to identify patterns of high-dimensional data by mapping participants to similar nodes based on T-scores (MCLUST R package). Random forest models were used to determine how sociodemographic (e.g., age, education), clinical (e.g., depressive symptoms, substance use disorder), and biological (e.g., HIV disease characteristics) factors differentially related to membership within a cognitive profile. All analyses were repeated within sex. Three cognitive profiles were identified overall and within each sex. Overall and within MWH, there were unimpaired and global weakness profiles. The third profile in the total sample demonstrated relatively weak auditory attention whereas in MWH showed relative strengths in attention and processing speed. Conversely, there was no unimpaired profile among WWH. Rather, WWH demonstrated separate profiles reflecting weakness in motor skills, a relative weakness in learning and delayed recall, and global weaknesses with spared recognition memory. Despite different cognitive profiles by sex, the most discriminative factors were similar between men and women and included reading level (cognitive reserve), current and nadir CD4 count, plasma HIV viral load, duration of HIV disease, age, depressive symptoms, and race/ethnicity. Findings fill a knowledge gap concerning sex differences in cognitive impairment in PWH and inform personalized risk reduction and therapeutic strategies.

RESUMEN

BACKGROUND: African Americans are disproportionally affected by HIV and have poorer rates of antiretroviral therapy (ART) adherence compared to other racial or ethnic groups in the United States. Factors associated with poor HIV disease outcomes are commonly associated with sociostructural barriers that prevent engagement with and retention in HIV care. SMS text messaging interventions to promote ART adherence among predominantly non-Hispanic White persons with HIV (PWH) have been shown to be efficacious; however, limited research has been devoted to culturally tailoring interventions for underrepresented racial/ethnic groups. Considering African Americans show poorer engagement along the HIV care continuum, we developed an individualized and culturally tailored two-way SMS text messaging intervention to improve ART adherence and associated virologic suppression among African American PWH. OBJECTIVE: In this paper we describe the protocol of a culturally tailored individualized Texting for Adherence Building (iTAB) intervention in a 24- to 48-week, single-arm study. METHODS: We developed a culturally tailored iTAB intervention, which we are implementing in a 24- to 48-week, single-arm study. Participants were recruited from the Family Health Centers of San Diego (FHCSD), a federally qualified health center. Patient inclusion criteria were (1) receiving care at the FHCSD, (2) living with HIV, (3) self-identification as Black, African American, or of African ancestry, (4) English speaking, (5) age 18 or older, (6) currently on ART, and (7) able to provide informed consent. Study enrollment began in November 2017 and closed in July 2019. A total of 90 participants from the FHCSD enrolled in the iTAB intervention, and we anticipate completing data collection in July 2020. Participants were assisted in individualizing and customizing their SMS text message preferences at the baseline study visit. Self-assessment measures are collected at baseline, interim, and final study visits. Problems related to sending/receiving SMS text messages and barriers to ART adherence are assessed at each interim study visit. The FHCSD staff monitors and tracks participants' daily SMS text message responses to ART adherence reminders using a clinical dashboard. RESULTS: We hypothesize that the proportion of individuals achieving HIV virologic suppression (viral load <40 copies/mL) will be greater at the end of the intervention period compared to the proportion prior to study implementation. Additionally, we anticipate that rates of virologic suppression at the end of the intervention among participants receiving iTAB will be comparable to those among the general FHCSD non-African American population who did not receive iTAB. Finally, we anticipate a high response rate to iTAB SMS text messages as well as positive participant feedback at the end of the intervention with regard to the acceptability of, satisfaction with, and perceived efficacy of iTAB. CONCLUSIONS: The iTAB intervention is a novel individualized two-way SMS text messaging intervention that has been culturally tailored for use among African Americans with HIV. We anticipate that iTAB will demonstrate efficacy in future randomized control trials and will be supportive of medication adherence among other populations facing health disparities.

RESUMEN

INTRODUCTION: As the frequency and intensity of natural disasters increases, disaster preparedness is necessary for individuals with disabilities, including those with spinal cord injury (SCI). However, despite vulnerability to poorer outcomes, disaster preparedness for individuals with SCI is inadequate. Telemedicine has been effectively used to mitigate the impact of natural disasters. In this case study, we describe the provision of clinical care, via telemedicine, to an individual with SCI who was affected by the California Valley Fire in 2015. CASE PRESENTATION: The individual described was an adult who sustained a SCI. Before discharge from acute inpatient rehabilitation, they enrolled in a research study, through which they received outpatient SCI-specific care via telemedicine (teleSCI). The participant attended several teleSCI visits prior to the start of the Valley Fire. In the midst and immediate aftermath of prolonged wildfire, and despite experiencing significant personal loss as a result of the fire, the participant continued to receive teleSCI services. TeleSCI was used to address emergent and extant medical concerns and to facilitate replacement of medical supplies and equipment destroyed by fire. DISCUSSION: TeleSCI was used to provide continuity of care and was responsive to the needs of an individual with SCI severely affected by wildfire. Emergency preparedness that meets the needs of persons with disabilities is critical during times of crisis. Telemedicine may be an effective tool that can be applied to meet the medical needs of individuals with SCI and to mitigate the impact of disasters.

RESUMEN

African Americans are disproportionately affected by HIV and socio-structural barriers that impact antiretroviral (ART) adherence. Two-way text-messaging interventions have shown promise in supporting adherence in US studies of mostly White people living with HIV (PLWH). However, culturally-appropriate tailoring is necessary to maximize intervention effectiveness among other racial/ethnic groups. Thus, to refine an existing text-messaging intervention, we examined barriers and facilitators to ART adherence among African Americans and perspectives on features to integrate into the extant intervention. Three focus groups, two with African American PLWH (n = 5 and n = 7) and one with providers of care (n = 11) were conducted; transcripts of audio-recordings were thematically analyzed. Adherence supports operated at individual, interpersonal, and structural/environmental levels (e.g., using reminders and pill organizers, wanting to protect partners from HIV, and positive interactions with providers). Adherence barriers also operated at multiple ecological levels (e.g., poor mental health, fear of disclosure of HIV status, and unstable housing). Participant-suggested features for refinement included: i) matching content to participants' comfort with receiving messages referencing HIV or medication-taking, ii) culturally-tailoring content for African Americans, iii) tracking adherence, and iv) encouraging adherence interactions between patients and providers. Feedback from both patients and providers is foundational to designing effective ART interventions among African American PLWH.

RESUMEN

BACKGROUND: Methamphetamine use poses a barrier to antiretroviral therapy (ART) adherence. Black and Hispanic men who have sex with men living with HIV (PLWH) shoulder much of the health burden resulting from the methamphetamine and HIV syndemic. Smartphones are nearly ubiquitous in the USA and may be promising vehicles for delivering interventions for ART adherence and drug use cessation. However, the acceptability of using applications to collect sensitive information and deliver feedback in this population has not been adequately explored. OBJECTIVE: This study examined minority PLWH's appraisals of the risks of participating in smartphone-based research to promote ART adherence in the context of methamphetamine use and explored their views on appropriate steps to mitigate perceived risks of participation. METHODS: Three focus groups were conducted among Black and Hispanic PLWH who use methamphetamine. Of the 13 participants, 5 had previously participated in a smartphone-based observational study of ART adherence and substance use. Discussants provided feedback on smartphone-based research, including receiving probes for HIV medication adherence, mood, and substance use as well as feedback on passive location-tracking for personalized messages. Transcribed audio-recordings were thematically coded and analyzed using the qualitative software MAXQDA. RESULTS: Participants expressed confidentiality concerns related to potential unintentional disclosure of their HIV status and methamphetamine use and to possible legal consequences. They additionally expressed concerns around the invasiveness of daily assessments and the potential of methamphetamine use questions to trigger cravings. To mitigate these concerns, they suggested maintaining participant privacy by indirectly asking sensitive questions, focusing on positive behaviors (e.g., number of days sober), allowing user-initiated reporting of location to tailor messages, and ensuring adequate data protections. In addition to financial compensation, participants cited altruism (specifically, continuing a tradition of volunteerism in HIV research) as a motivator for potentially engaging in such research. CONCLUSIONS: Minority PLWH have concerns regarding the use of smartphones for ART adherence and methamphetamine sobriety intervention research. However, minority PLWH are likely to participate if studies include appropriate protections against risks to confidentiality and experimental harm and are designed to offer future benefit to themselves and other PLWH.

RESUMEN

The effectiveness of pre-exposure prophylaxis (PrEP) against HIV acquisition depends on treatment adherence; however, within-person associations between levels of PrEP adherence and engagement in condomless sex have not been well studied. In the context of a demonstration project, 372 men who have sex with men received once-daily PrEP and completed six study visits over 48 weeks. Two-part growth mixture modeling was used to examine the longitudinal trajectory of condomless anal intercourse (CAI) and self-reports of PrEP adherence, controlling for relevant covariates. Over time, greater PrEP adherence was contemporaneously associated with both a higher likelihood of engaging in any CAI and with a greater number of CAI acts. Substance use was also associated with a higher likelihood of engaging in CAI. Contemporaneous associations between self-reported PrEP adherence and CAI suggest that adherence behaviors may be motivated by the desire to mitigate risk of HIV infection; however, exact directionality is unknown.


RESUMEN: La eficacia de la profilaxis Pre-exposición (PrEP) contra la adquisición del VIH depende de la adherencia al tratamiento; sin embargo, las asociaciones dentro de la persona entre los niveles de adherencia a PrEP y la participación en el sexo sin condón no han sido bien estudiadas. En un proyecto de demostración, 372 hombres que tienen relaciones sexuales con hombres recibieron PrEP diariamente y completaron seis visitas de estudio durante 48 semanas. El modelado de mezclas de crecimiento en dos partes se utilizó para examinar la trayectoria longitudinal de las relaciones sexuales anales sin condonación (CAI) y los autoinformes de adherencia a PrEP, controlando las covariables pertinentes. Con el tiempo, una mayor adherencia a PrEP se asoció a la misma vez con una mayor probabilidad de participar en cualquier CAI y tambien con un mayor número de CAI. El consumo de sustancias también se asoció con una mayor probabilidad de participar en CAI. Las asociaciones contemporáneas entre la adherencia a PrEP autoinformada y CAI sugieren que los comportamientos de adherencia pueden estar motivados por el deseo de mitigar el riesgo de infección por el VIH; sin embargo, se desconoce la direccionalidad exacta.

RESUMEN

BACKGROUND: Higher cumulative burden of depression among people with HIV (PWH) is associated with poorer health outcomes; however, longitudinal relationships with neurocognition are unclear. This study examined hypotheses that among PWH, (1) higher cumulative burden of depression would relate to steeper declines in neurocognition, and (2) visit-to-visit depression severity would relate to fluctuations in neurocognition within persons. SETTING: Data were collected at a university-based research center from 2002 to 2016. METHODS: Participants included 448 PWH followed longitudinally. All participants had >1 visit (M = 4.97; SD = 3.53) capturing depression severity (Beck Depression Inventory-II) and neurocognition (comprehensive test battery). Cumulative burden of depression was calculated using an established method that derives weighted depression severity scores by time between visits and total time on study. Participants were categorized into low (67%), medium (15%), and high (18%) depression burden. Multilevel modeling examined between- and within-person associations between cumulative depression burden and neurocognition over time. RESULTS: The high depression burden group demonstrated steeper global neurocognitive decline compared with the low depression burden group (b = -0.100, P = 0.001); this was driven by declines in executive functioning, delayed recall, and verbal fluency. Within-person results showed that compared with visits when participants reported minimal depressive symptoms, their neurocognition was worse when they reported mild (b = -0.12, P = 0.04) or moderate-to-severe (b = -0.15, P = 0.03) symptoms; this was driven by worsened motor skills and processing speed. CONCLUSIONS: High cumulative burden of depression is associated with worsening neurocognition among PWH, which may relate to poor HIV-related treatment outcomes. Intensive interventions among severely depressed PWH may benefit physical, mental, and cognitive health.
