Sociotechnical feasibility of natural language processing-driven tools in clinical trial eligibility prescreening for Alzheimer's disease and related dementias

BACKGROUND

Alzheimer's disease and related dementias (ADRD) affect over 55 million globally. Current clinical trials suffer from low recruitment rates, a challenge potentially addressable via natural language processing (NLP) technologies for researchers to effectively identify eligible clinical trial participants.

OBJECTIVE

This study investigates the sociotechnical feasibility of NLP-driven tools for ADRD research prescreening and analyzes the tools' cognitive complexity's effect on usability to identify cognitive support strategies.

METHODS

A randomized experiment was conducted with 60 clinical research staff using three prescreening tools (Criteria2Query, Informatics for Integrating Biology and the Bedside [i2b2], and Leaf). Cognitive task analysis was employed to analyze the usability of each tool using the Health Information Technology Usability Evaluation Scale. Data analysis involved calculating descriptive statistics, interrater agreement via intraclass correlation coefficient, cognitive complexity, and Generalized Estimating Equations models.

RESULTS

Leaf scored highest for usability followed by Criteria2Query and i2b2. Cognitive complexity was found to be affected by age, computer literacy, and number of criteria, but was not significantly associated with usability.

DISCUSSION

Adopting NLP for ADRD prescreening demands careful task delegation, comprehensive training, precise translation of eligibility criteria, and increased research accessibility. The study highlights the relevance of these factors in enhancing NLP-driven tools' usability and efficacy in clinical research prescreening.

CONCLUSION

User-modifiable NLP-driven prescreening tools were favorably received, with system type, evaluation sequence, and user's computer literacy influencing usability more than cognitive complexity. The study emphasizes NLP's potential in improving recruitment for clinical trials, endorsing a mixed-methods approach for future system evaluation and enhancements.

Assessing Preferences for Long-Acting Injectable PrEP Among Young Adult Sexual Minority Men and Transgender Women

PURPOSE

Oral pre-exposure prophylaxis (PrEP) is effective in preventing HIV transmission. However, oral PrEP uptake is low, particularly among sexual and gender minority youth who are vulnerable to HIV infection. Alternative methods of PrEP delivery, such as long-acting injectable (LAI) PrEP may overcome barriers and be preferred. However, attitudes and preferences of younger sexual and gender minorities towards LAI PrEP have not been well studied. The purpose of this study is to describe preferences for initiating LAI PrEP among sexual and gender minority youth.

METHODS

We analyzed data collected as part of an HIV prevention randomized trial from January 2022 to February 2023, using multiple regression to identify factors associated with a preference for LAI PrEP.

RESULTS

The study sample (N=265) was 50% youth of color, mean age 25 years (SD=3.4, range=18-31), and primarily identified as gay (71%) and male (91%). 42% had heard of LAI PrEP and 31% preferred LAI PrEP over other prevention methods. In multiple regression analysis, LAI PrEP preference was associated with identifying as White, previous PrEP experience, and perceived LAI PrEP efficacy.

DISCUSSION

We conclude that gaps in awareness exist for LAI PrEP, however it may be preferred over other prevention methods especially in White youth, those with PrEP experience and higher perceptions of its efficacy. More education and outreach are needed to prevent extension of existing race/ethnicity disparities in use of oral daily PrEP to LAI PrEP.

WHAT'S NEW

Findings from this study suggest that awareness of LAI PrEP is low, however it may be preferred over other prevention methods especially in White youth, those with PrEP experience and higher perceptions of its efficacy.

Comparison of evaluation methods for improving the usability of a Spanish mHealth tool

OBJECTIVE

Mobile health (mHealth) technology is now widely used across health conditions and populations. The rigorous development of these tools has yielded improved health outcomes, yet the ideal approach for developing mHealth tools continues to evolve, indicating the need for rigorous usability evaluation methods. This study compares two usability evaluation methods - cognitive interviews and usability assessments employing a think-aloud approach - for adapting an evidence-based mHealth tool from English into Spanish.

METHODS

We conducted cognitive interviews and usability assessments using a think-aloud protocol to evaluate the usability of an HIV mHealth application among 40 Spanish-speaking adults with HIV in New York City, NY, and La Romana, Dominican Republic. The Health IT Usability Evaluation Model (Health-ITUEM) was used to guide the analysis of qualitative data collected from each method.

RESULTS

Participants (N = 40) averaged 43 years old (SD = 12.26; range 20-79), identified primarily Hispanic/Latino (92.5 %), and resided in La Romana (50 %) or New York City (50 %). Both usability evaluation methods yielded similar findings, highlighting learnability and information needs as crucial components of participant feedback for the mHealth application. Cognitive interviews captured participants' perspectives on the app's interface and design. On the other hand, results from usability assessments offered insights into participants' competency while interacting with the mHealth tool.

CONCLUSION

Findings from this study highlight the contributions and limitations of including cognitive interviews and task-based usability assessments using a think-aloud approach in mHealth usability testing. Future research should employ a multi-method approach, incorporating complementary usability evaluation methods and engaging participants in multiple assessments. Using complementary usability evaluation methods may provide a more comprehensive understanding of the usability and participant experience aspects of a mHealth tool compared to using a single usability evaluation method.

Usability testing of a mobile health application to support individuals with active tuberculosis: a mixed methods study

Poor adherence to tuberculosis (TB) treatment leads to further disease transmission, worsened outcomes, and the development of drug resistance. Digital adherence technologies may facilitate a more patient-centered approach for improving TB treatment outcomes than current strategies. The objective of this study was to evaluate and explore improving usability of the TB Treatment Support Tools (TB-TST) mobile application. We used an iterative convergent mixed-method design consisting of two quantitative surveys and a qualitative think-aloud interview. Testing was conducted in three testing cycles consisting of a total of 16 interviews and 26 surveys. Results were thematically analyzed and reported to the development team during weekly team meetings. Participants rated the TB-TSTs application as having high usability and the iterative approach resulted in several refinements to the application in response to participant feedback. These refinements were well received during qualitative interviews but did not result in a statistically significant improvement in usability testing scores between cycles. Using an iterative convergent mixed-method design was an effective method for refining our mHealth application. Data collected from think-aloud interviews, the MAUQ, and the Health-ITUES identified key areas of application design that needed refinement.

Examining who is conducting and leading National Institute of Health-funded research in U.S. schools of nursing

BACKGROUND

Nursing science is essential for generating a unique body of knowledge that is foundational to the academic discipline of nursing.

PURPOSE

The goal of this analysis is to detail the education and licensing of faculty and leadership in research-intensive schools of nursing and to present the current data on the National Institute of Health (NIH) funding patterns in schools of nursing.

METHODS

The faculty composition analysis focused on the 40 U.S. schools of nursing receiving the most NIH funding through faculty serving as PIs on grants awarded in 2023. For the NIH funding patterns analysis, data were extracted from the NIH RePORTER database.

DISCUSSION

Of the top 30 NIH-funded Schools of Nursing, all the Deans and Associate Deans of Academic Affairs are educated or licensed as nurses; whereas only 55% of Associate Deans of Research are educated or licensed as nurses. In 2022, nearly half of the top-ranked schools of nursing had less than half of their NIH funding awarded to faculty who are trained and licensed as nurses CONLUSION: The current trends in the research enterprise in schools of nursing implore us to assess if we are adequately training nurses to advance nursing science and more importantly to serve as leaders of nursing science.

Exploring the Interrelationships Between Physical Function, Functional Exercise Capacity, and Exercise Self-Efficacy in Persons Living with HIV

PURPOSE

To determine if there were differences between the subjective and objective assessments of physical activity while controlling for sociodemographic, anthropometric, and clinical characteristics.

SETTING/SAMPLE

A total of 810 participants across eight sites located in three countries.

MEASURES

Subjective instruments were the two subscales of Self-efficacy for Exercise Behaviors Scale: Making Time for Exercise and Resisting Relapse and Patient-Reported Outcomes Measurement Information System, which measured physical function. The objective measure of functional exercise capacity was the 6-minute Walk Test.

ANALYSIS

Both univariate and multivariant analyses were used.

RESULTS

Physical function was significantly associated with Making Time for Exercise (β = 1.76, p = .039) but not with Resisting Relapse (β = 1.16, p = .168). Age (β = -1.88, p = .001), being employed (β = 16.19, p < .001) and race (βs = 13.84-31.98, p < .001), hip-waist ratio (β = -2.18, p < .001), and comorbidities (β = 7.31, p < .001) were significant predictors of physical functioning. The model predicting physical function accounted for a large amount of variance (adjusted R2 = .938). The patterns of results predicting functional exercise capacity were similar. Making Time for Exercise self-efficacy scores significantly predicted functional exercise capacity (β = 0.14, p = .029), and Resisting Relapse scores again did not (β = -0.10, p = .120). Among the covariates, age (β = -0.16, p < .001), gender (β = -0.43, p < .001), education (β = 0.08, p = .026), and hip-waist ratio (β = 0.09, p = .034) were significant. This model did not account for much of the overall variance in the data (adjusted R2 = .081). We found a modest significant relationship between physical function and functional exercise capacity (r = 0.27).

CONCLUSIONS

Making Time for Exercise Self-efficacy was more significant than Resisting Relapse for both physical function and functional exercise capacity. Interventions to promote achievement of physical activity need to use multiple measurement strategies.

Examining racial differences in the network structure and properties of specific cognitive domains among older adults

Older adults oftentimes experience cognitive aging which leads to varying degrees of cognitive impairment. Previous studies have found that racial and ethnic disparities exist in the prevalence and severity of cognitive impairment among older adults. Yet, little is known on the relationship among specific cognitive domains and how this relationship differs between African American and White older adults. This is a secondary data analysis of Wave II (2010-2011) data from the National Social Life, Health, and Aging Project (NSHAP). A total of 2,471 older adults aged between 65 and 85 years old (African American n = 452, White n = 2019) were included. Network analysis was used to visualize and characterize the network structure and to examine network stability. Then, network comparison test was conducted to compare the network properties of the cognitive network structure between African American and White older adults. African American older adults had a lower cognitive function in all cognitive domains than White older adults. While there was no significant difference in global strength, there was a significant difference in the network structure and strength centrality measure between the two groups (p < 0.05). The invariance edge strength test found the language-visuospatial edge to be significantly stronger in African American older adults. Clinicians need to understand the different cognitive function across multiple cognitive domains between African American and White older adults and routinely offer targeted and timely cognitive assessment and management in this population.

Identifying Key Factors to PrEP Initiation and Persistence Among YMSM Through Focus Groups and Surveys in Two High-Priority Settings

Cisgender men are diagnosed with HIV at a rate four times greater than cisgender women, with 71% of infections attributed to male-male sexual contact. Despite expanding accessibility, pre-exposure prophylaxis (PrEP) for HIV prevention is initiated by only 30% of people with PrEP indications. Five focus groups with 42 young men who have sex with men from New York and Alabama were conducted to identify key factors to PrEP initiation and persistence. Thirty focus group participants completed a survey on demographics, PrEP choices and health care attitudes. Findings suggest provider competency significantly influences PrEP use due to stigmatization in medical settings. Participants noted benefits of PrEP including HIV protection and sexual empowerment, yet barriers like cost and side effects were prevalent. Our findings outline barriers and facilitators to PrEP use among young men who have sex with men in two high priority settings that will inform PrEP care updates in participating clinics.

Examining the Intersection of Ethnoracial Disparities and HIV Status in Substance Use Risks among U.S. Adults

Black/African American and Hispanic Americans experience significant HIV-related disparities. Substance use might be a contributing factor to these disparities, but there is limited research on this topic. This study investigated various substance use risks by HIV status and race/ethnicity (Black, Hispanic, White) among U.S. adults. We used data from the 2005-2019 National Survey on Drug Use and Health (N = 541,921). In each racial/ethnic group, the prevalence rates of past-year and past-month tobacco, alcohol, cannabis, and cocaine use, and past-year alcohol and illicit drug use disorders were estimated by HIV status. A series of logistic regressions with the interaction term of HIV x race/ethnicity were performed to examine race/ethnicity's moderating effect on the HIV-substance use associations, while controlling for sociodemographic factors and survey year. Moderation analysis showed that HIV status's association with the risks of past-year tobacco use (AOR = 1.67, 95% CI = 1.01-2.75), past-year cocaine use (AOR = 3.80, 95% CI = 1.91-7.57), past-month cocaine use (AOR = 5.34, 95% CI = 2.10-13.60), and past-year alcohol use disorder (AOR = 2.52, 95% CI = 1.29-4.92) differed significantly between Black and White adults. Between the Hispanic and White groups, HIV status's association with the risks of past-year alcohol use (AOR = 2.00, 95% CI = 1.09-3.69), past-year cocaine use (AOR = 2.40, 95% CI = 1.06-5.39), and past-month cocaine use (AOR = 3.69, 95% CI = 1.36-10.02) also differed significantly. It is well-established that individuals with HIV face an elevated risk of substance use. Our study added valuable insights by highlighting that this phenomenon is particularly more significant among Black and Hispanic adults for several substances when compared to White adults. Implications for practice are discussed.

A pilot test of an infographic-based health communication intervention to enhance patient education among Latino persons with HIV

OBJECTIVE

To pilot test an infographic-based health communication intervention that our team rigorously designed and explore whether its implementation leads to better health outcomes among Latino persons with HIV (PWH).

MATERIALS AND METHODS

Latino PWH (N = 30) living in New York City received the intervention during health education sessions at 3 study visits that occurred approximately 3 months apart. At each visit, participants completed baseline or follow-up assessments and laboratory data were extracted from patient charts. We assessed 6 outcomes (HIV-related knowledge, self-efficacy to manage HIV, adherence to antiretroviral therapy, CD4 count, viral load, and current and overall health status) selected according to a conceptual model that describes pathways through which communication influences health outcomes. We assessed changes in outcomes over time using quantile and generalized linear regression models controlling for the coronavirus disease 2019 (COVID-19) research pause and new patient status (new/established) at the time of enrollment.

RESULTS

Most participants were male (60%) and Spanish-speaking (60%); 40% of participants identified as Mixed Race/Mestizo, 13.3% as Black, 13.3% as White, and 33.3% as "other" race. Outcome measures generally improved after the second intervention exposure. Following the third intervention exposure (after the COVID-19 research pause), only the improvements in HIV-related knowledge and current health status were statistically significant.

DISCUSSION AND CONCLUSION

Our infographic-based health communication intervention may lead to better health outcomes among Latino PWH, but larger trials are needed to establish efficacy. From this work, we contribute suggestions for effective infographic use for patient-provider communication to enhance patient education in clinical settings.

Development and evaluation of visualizations of smoking data for integration into the Sense2Quit app for tobacco cessation

IMPORTANCE

Due to insufficient smoking cessation apps for persons living with HIV, our study focused on designing and testing the Sense2Quit app, a patient-facing mHealth tool which integrated visualizations of patient information, specifically smoking use.

OBJECTIVES

The purpose of this paper is to detail rigorous human-centered design methods to develop and refine visualizations of smoking data and the contents and user interface of the Sense2Quit app. The Sense2Quit app was created to support tobacco cessation and relapse prevention for people living with HIV.

MATERIALS AND METHODS

Twenty people living with HIV who are current or former smokers and 5 informaticians trained in human-computer interaction participated in 5 rounds of usability testing. Participants tested the Sense2Quit app with use cases and provided feedback and then completed a survey.

RESULTS

Visualization of smoking behaviors was refined through each round of usability testing. Further, additional features such as daily tips, games, and a homescreen were added to improve the usability of the app. A total of 66 changes were made to the Sense2Quit app based on end-user and expert recommendations.

DISCUSSION

While many themes overlapped between usability testing with end-users and heuristic evaluations, there were also discrepancies. End-users and experts approached the app evaluation from different perspectives which ultimately allowed us to fill knowledge gaps and make improvements to the app.

CONCLUSION

Findings from our study illustrate the best practices for usability testing for development and refinement of an mHealth-delivered consumer informatics tool for improving tobacco cessation yet further research is needed to fully evaluate how tools informed by target user needs improve health outcomes.

A randomized controlled trial of the dissemination of an mHealth intervention for improving health outcomes: the WiseApp for Spanish-speakers living with HIV study protocol

BACKGROUND

While there is no cure for HIV, adherence to antiretroviral therapy can extend the lifespan and improve the quality of life of people with HIV. Despite the global reduction of HIV infection rates in recent years, New York City and La Romana, Dominican Republic, continue to report high infection rates among Latino populations. Many people with HIV remain virally unsuppressed in these geographic hotspots, suggesting a need for additional interventions to overcome medication adherence barriers. Tailored and culturally appropriate mobile health (mHealth) technology can be an engaging way to improve adherence. The primary objective of this trial is to test the effectiveness of an mHealth tool to improve HIV medication adherence among Spanish-speaking people living in New York City and the Dominican Republic.

METHODS

The WiseApp study is a two-arm randomized controlled trial among 248 people with HIV across the New York and Dominican Republic sites over the course of 12 months. Participants are randomly assigned to either receive a CleverCap pill bottle that is linked to the WiseApp (intervention) or standard of care (control). All participants complete surveys at baseline, 3-month, 6-month, and 12-month follow-up visits and the study team obtains HIV-1 viral load and CD4 count results through blood draw at each study timepoint.

DISCUSSION

The use of mHealth technologies to improve medication adherence among people with HIV has been implemented in recent years. Although some studies have found improvement in adherence to antiretroviral therapy in the short term, there is limited information about how these interventions improve adherence among Spanish-speaking populations. Disproportionate rates of HIV infection among Latinos in New York City suggest an existing inequitable approach in reaching and treating this population. Due to a lack of mHealth studies with Latino populations, and apps tailored to Spanish-speakers, the WiseApp study will not only demonstrate the effectiveness of this particular mHealth app but will also contribute to the mHealth research community as a whole.

TRIAL REGISTRATION

This trial was registered with Clinicaltrials.gov (NCT05398185) on 5/31/2022.

An Examination of the Non-linear Relationship Between Cognition and Total Hemoglobin Among the Cognitively Normal Older Adults by Gender

Objectives: This exploratory study aimed to identify the potential non-linear relationship between hemoglobin (Hgb) and cognition among cognitively normal older adults and how this relationship differs in terms of gender in generalized additive models (GAM). Methods: This is a secondary data analysis using Wave II (2010-2011) data from the National Social Life, Health, and Aging Project. A generalized additive model was used to understand the non-linear relationship between Hgb and cognition, and to identify critical Hgb point related to cognition. Results: While both genders had a non-linear association between Hgb and cognition, the degree of non-linearity was more pronounced in male older adults with EDF value close to 2. The inflection point of 15.10 g/dL for male older adults and inflection point of 11.72 g/dL for female older adults were obtained. Conclusion: Further studies are needed to validate these results and develop precision medicine approaches to integrate these results into clinical practice.

The Social, Mental, and Physical Health Impacts of the COVID-19 Pandemic on People With HIV: Protocol of an Observational International Multisite Study

ABSTRACT

As the COVID-19 pandemic spread across the world, immunocompromised individuals such as people with HIV (PWH) may have faced a disproportionate impact on their health and HIV outcomes, both from COVID-19 and from the strategies enacted to contain it. Based on the SPIRIT guidelines, we describe the protocol for an international multisite observational study being conducted by The International Nursing Network for HIV Research, with the Coordinating Center based at the University of California, San Francisco (UCSF) School of Nursing. Site Principal Investigators implement a standardized protocol to recruit PWH to complete the study online or in-person. Questions address demographics; HIV continuum of care indicators; mental and social health; COVID-19 and vaccination knowledge, attitudes, behaviors, and fears; and overall outcomes. Results of this study will contribute to knowledge that can inform responses to future public health crises to minimize their impacts on vulnerable populations such as PWH.

Do Walk Step Reminders Improve Physical Activity in Persons Living With HIV in New York City?-Results From a Randomized Clinical Trial

ABSTRACT

Supervised physical activity can increase functional capacity in persons with HIV (PWH); however, aerobic interventions have shown little improvement in overall physical activity in PWH. In response, we sought to assess the effect of wearing a fitness tracker (FitBit) paired with walk step reminders delivered through an mHealth application to improve physical activity and decreasing body mass index among PWH in New York City. There was no significant difference in the frequency of walk steps between participants in the control group and intervention group from baseline to 6-month follow-up. These findings show that walk step reminders alone were inadequate for sustained improvement of physical activity. This study highlights the need to develop and test the comparative efficacy of physical activity interventions that are tailored to the unique needs and capabilities of PWH. Future interventions should incorporate fitness tracking with tailored interventions focused on the promotion of physical activity.Clinical Trials.Gov Registration number: NCT03205982.

Racial Differences in Older Adult's Mental Health and Cognitive Symptomatology: Identifying Subgroups Using Multiple-Group Latent Class Analysis

INTRODUCTION

Little is known on the potential racial differences in latent subgroup membership based on mental health and cognitive symptomatology among older adults.

METHODS

This is a secondary data analysis of Wave 2 data from the National Social Life, Health, and Aging Project (N = 1819). Symptoms were depression, anxiety, loneliness, happiness, and cognition. Multiple-group latent class analysis was conducted to identify latent subgroups based on mental health and cognitive symptoms and to compare these differences between race.

RESULTS

Class 1: "Severe Cognition & Mild-Moderate Mood Impaired," Class 2: "Moderate Cognition & Mood Impaired," and Class 3: "Mild Cognition Impaired & Healthy Mood" were identified. Black older adults were more likely to be in Class 1 while White older adults were more likely to be in Class 2 and Class 3.

DISCUSSION

Clinicians need to provide culturally-sensitive care when assessing and treating symptoms across different racial groups.

Pilot Testing of an mHealth App for Tobacco Cessation in People Living With HIV: Protocol for a Pilot Randomized Controlled Trial

BACKGROUND

An estimated 40% of people living with HIV smoke cigarettes. Although smoking rates in the United States have been declining in recent years, people living with HIV continue to smoke cigarettes at twice the rate of the general population. Mobile health (mHealth) technology is an effective tool for people living with a chronic illness, such as HIV, as currently 84% of households in the United States report that they have a smartphone. Although many studies have used mHealth interventions for smoking cessation, few studies have recruited people living with HIV who smoke.

OBJECTIVE

The objective of the pilot randomized controlled trial (RCT) is to examine the feasibility, acceptability, and preliminary efficacy of the Sense2Quit App as a tool for people living with HIV who are motivated to quit smoking.

METHODS

The Sense2Quit study is a 2-arm RCT for people living with HIV who smoke cigarettes (n=60). Participants are randomized to either the active intervention condition, which consists of an 8-week supply of nicotine replacement therapy, standard smoking cessation counseling, and access to the Sense2Quit mobile app and smartwatch, or the control condition, which consists of standard smoking cessation counseling and a referral to the New York State Smokers' Quitline. The Sense2Quit app is a mobile app connected through Bluetooth to a smartwatch that tracks smoking gestures and distinguishes them from other everyday hand movements. In the Sense2Quit app, participants can view their smoking trends, which are recorded through their use of the smartwatch, including how often or how much they smoke and the amount of money that they are spending on cigarettes, watch videos with quitting tips, information, and distractions, play games, set reminders, and communicate with a study team member.

RESULTS

Enrollment of study participants began in March 2023 and is expected to end in October 2023. All data collection is expected to be completed by the end of January 2024. This RCT will test the difference in outcomes between the control and intervention arms. The primary outcome will be the percentage of participants with biochemically verified 7-day point prevalence smoking or tobacco abstinence at their 12-week follow-up. Results from this pilot study will be disseminated to the research community following the completion of all data collection.

CONCLUSIONS

The Sense2Quit study leverages mHealth so that it can help smokers improve their efforts at smoking cessation. Our research has the potential to not only increase quitting rates among people living with HIV who may need a prolonged, tailored intervention but also inform further development of mHealth for people living with HIV. This mHealth study will contribute significant findings to the greater mHealth research community, providing evidence as to how mHealth should be developed and tested among the target population.

Understanding Physical Activity Determinants in an HIV Self-Management Intervention: Qualitative Analysis Guided by the Theory of Planned Behavior

BACKGROUND

People living with HIV have long life expectancy and are experiencing more comorbid conditions, being at an increased risk for developing cardiovascular disease (CVD) and diabetes, further exacerbated due to the HIV or inflammatory process. One effective intervention shown to decrease mortality and improve health outcomes related to CVD and diabetes in people living with HIV is increased regular physical activity. However, people living with HIV often fall short of the daily recommended physical activity levels. While studies show that mobile health (mHealth) can potentially help improve people's daily activity levels and reduce mortality rates due to comorbid conditions, these studies do not specifically focus on people living with HIV. As such, it is essential to understand how mHealth interventions, such as wearables, can improve the physical activity of people living with HIV.

OBJECTIVE

This study aimed to understand participants' experiences wearing a fitness tracker and an app to improve their physical activity.

METHODS

In total, 6 focus groups were conducted with participants who completed the control arm of a 6-month randomized controlled trial (ClinicalTrials.gov NCT03205982). The control arm received daily walk step reminders to walk at least 5000 steps per day and focused on the overall wellness of the individual. The analysis of the qualitative focus groups used inductive content analysis using the theory of planned behavior as a framework to guide and organize the analysis.

RESULTS

In total, 41 people living with HIV participated in the focus groups. The majority (n=26, 63%) of participants reported their race as Black or African American, and 32% (n=13) of them identified their ethnicity as Hispanic or Latino. In total, 9 major themes were identified and organized following the theory of planned behavior constructs. Overall, 2 major themes (positive attitude toward tracking steps and tracking steps is motivating) related to attitudes toward the behavior, 2 major themes (social support or motivation from the fitness tracker and app and encouragement from family and friends) related to participant's subjective norms, 1 theme (you can adjust your daily habits with time) related to perceived behavioral control, 2 themes (reach their step goal and have a healthier lifestyle) related to participant's intention, and 2 themes (continuing to walk actively and regularly wearing the fitness tracker) related to participant's changed behavior. Participants highlighted how the mHealth interface with the avatar and daily step tracking motivated them to both begin and continue to engage in physical activity by adjusting their daily routines.

CONCLUSIONS

Findings from this study illustrate how features of mHealth apps may motivate people living with HIV to start and continue sustained engagement in physical activities. This sustained increase in physical activity is crucial for reducing the risk of comorbid conditions such as diabetes or CVD.

A Review of Serious Gaming as an Intervention for HIV Prevention

PURPOSEOF REVIEW

Young people face the highest number of new HIV infections globally. With today's increasing access to smartphones, serious games have been viewed as an effective means of improving knowledge and behavioral outcomes. This systematic review describes current HIV prevention serious games and their relationship with HIV-related knowledge and behavioral outcomes.

RECENT FINDINGS

A search of HIV prevention serious games was conducted using PubMed, CINAL, IEEE, Web of Science, and Google Scholar. A total of 31 papers were identified, which consist of 20 studies and 11 protocols. Results for knowledge, attitudes, intentions, and behaviors were mixed. Two interventions reported improvement in PrEP usage and optimal dosing. Gaming appears to be a viable and engaging method to improve knowledge, attitudes, and behavioral outcomes to promote HIV prevention among diverse groups of adolescents and young adults globally. However, additional research is needed to understand how to implement this modality effectively.

Serum inflammation markers associated with altered brain white matter microstructure in people with HIV on antiretroviral treatment

BACKGROUND

Many studies have reported reduced brain white matter fractional anisotropy (FA) and increased mean diffusivity (MD) on diffusion tensor imaging (DTI) of people with HIV (PWH). Few, however, have linked individual blood inflammatory markers with white matter tract-specific FA and MD.

METHODS

PWH 50 years old or older from New York, NY, USA, were invited to a cross-sectional study. Demographic data, blood samples, and brain DTI were obtained. Least absolute shrinkage and selection operator (LASSO) regression was used to examine associations between biomarkers and white matter tract-specific FA and MD. All models included age, sex, race, ethnicity, diabetes, hypertension, smoking, and viral load as control variables.

RESULTS

Seventy-two cases were analyzed. Mean age was 60 ± 6 years, 47% were women, 21% were Hispanic, and 78% were black. All had asymptomatic HIV infection and were on antiretroviral therapy. Eighty-nine percent had CD4 count >200 cell/mm3 and 78% were virally suppressed. Vascular endothelial growth factor (VEGF) and macrophage inflammatory proteins (MIP) 1β and 1α were consistently associated with lower FA and higher MD across white matter tracts.

CONCLUSIONS

Elevated serum VEGF, MIP-1α, and MIP-1β were associated with altered white matter microstructure. These blood biomarkers may help predict HIV-associated white matter damage.

A community health worker and mobile health app intervention to improve adherence to HIV medication among persons with HIV: the CHAMPS study protocol

BACKGROUND

Persons with HIV (PWH) can now achieve a near-normal life expectancy due to antiretroviral therapy (ART). Despite widespread availability of ART in the United States (US), many of the country's approximate 1.1 million PWH are not achieving viral suppression due to poor ART adherence. Viral suppression rates are particularly low in Alabama (AL, 62%) and New York City (NYC, 67%). There is mixed evidence on the efficacy of community health workers (CHW) and mHealth interventions for improving ART adherence and viral suppression in PWH thus, we sought to combine these interventions and test the efficacy for improving health outcomes in PWH.

METHODS

The CHAMPS study is a two-arm randomized controlled trial among 300 PWH with suboptimal primary care appointment adherence (n = 150 in AL and 150 in NYC) over the course of 12 months. Participants are randomly assigned to CHAMPS (intervention) or a standard-of-care (control) arm. Participants in the intervention arm are given a CleverCap pill bottle that syncs to the WiseApp to track medication adherence, reminds users to take their medication at a set time, and enables communication with CHW. All participants complete baseline, 6-month, and 12-month follow-up visits where surveys are administered and, CD4 and HIV-1 viral load are obtained through blood draw.

DISCUSSION

Maintaining ART adherence has significant implications in HIV management and transmission. mHealth technologies have been shown to optimize the provision of health services, produce positive changes in health behavior, and significantly improve health outcomes. CHW interventions also provide personal support to PWH. The combination of these strategies may provide the necessary intensity to increase ART adherence and clinic attendance among PWH at highest risk for low engagement. Delivering care remotely enables CHW to contact, assess, and support numerous participants throughout the day, reducing burden on CHW and potentially improving intervention durability for PWH. The adoption of the WiseApp coupled with community health worker sessions in the CHAMPS study has the potential to improve HIV health outcomes, and will add to the growing knowledge of mHealth and CHW efforts to improve PWH medication adherence and viral suppression.

TRIAL REGISTRATION

Expert Feedback on the Adaptation and Translation of Spanish Version of WiseApp

HIV-related disparities also exist in developing countries, such as the Dominican Republic, where minority groups and/or those with low socioeconomic status experience higher disease burdens and worse health outcomes than those with higher socioeconomic status. We used a community-based approach to ensure the WiseApp intervention is culturally relevant and addresses the needs of our target population. Expert panelists made recommendations on how to simplify the language and features of the WiseApp to accommodate Spanish-speaking users who may have lower levels of education, or color or vision deficiencies.

A Cross-sectional Study of Perceived Stress and Racial Discrimination Among a National Sample of Young Men Who Have Sex With Men

ABSTRACT

Research regarding the impact of racism on stress among young men who have sex with men (YMSM) is sparse. Secondary data were assessed from a 2018-2020 national mHealth prevention trial for YMSM aged 13-18 years (N = 542). Linear regression models examined associations between perceived stress and interpersonal and vicarious racism, adjusting for covariates. Stratified models by race/ethnicity were included. A subanalysis (n = 288) examined associations between nine interpersonal racial discriminatory events and perceived stress. Over 50% of participants experienced racial discrimination. In the multivariable models, exposure to interpersonal (β = 1.43, p-value: .038) and vicarious (β = 1.77, p-value: .008) racism was associated with perceived stress because there were four interpersonal racial discriminatory events. Stratified analysis by race/ethnicity found significant associations between interpersonal and vicarious racism and perceived stress among some racial/ethnic groups. Racial discrimination was common among YMSM, making them susceptible to the possible effects of vicarious and interpersonal racism on stress.

Changes in high-risk sexual behavior, HIV and other STI testing, and PrEP use during the COVID-19 pandemic in a longitudinal cohort of adolescent men who have sex with men 13 to 18 years old in the United States

The COVID-19 pandemic has disrupted sexual health services among those most vulnerable to HIV acquisition, such as adolescent men who have sex with men (AMSM). We sought to characterize the changes in sexual-risk behaviors, HIV and other STI testing, and pre-exposure prophylaxis (PrEP) use among a longitudinal cohort of AMSM aged 13 to 18 years before and during the COVID-19 pandemic. We observed a significant decline in HIV testing and a marginal decrease in other STI testing since the pandemic began in March 2020. Outreach efforts and innovative remote delivery of sexual health services are needed to support access to healthcare services among AMSM as the pandemic persists.

Clinical research staff perceptions on a natural language processing-driven tool for eligibility prescreening: An iterative usability assessment

BACKGROUND

Participant recruitment is a barrier to successful clinical research. One strategy to improve recruitment is to conduct eligibility prescreening, a resource-intensive process where clinical research staff manually reviews electronic health records data to identify potentially eligible patients. Criteria2Query (C2Q) was developed to address this problem by capitalizing on natural language processing to generate queries to identify eligible participants from clinical databases semi-autonomously.

OBJECTIVE

We examined the clinical research staff's perceived usability of C2Q for clinical research eligibility prescreening.

METHODS

Twenty clinical research staff evaluated the usability of C2Q using a cognitive walkthrough with a think-aloud protocol and a Post-Study System Usability Questionnaire. On-screen activity and audio were recorded and transcribed. After every-five evaluators completed an evaluation, usability problems were rated by informatics experts and prioritized for system refinement. There were four iterations of system refinement based on the evaluation feedback. Guided by the Organizational Framework for Intuitive Human-computer Interaction, we performed a directed deductive content analysis of the verbatim transcriptions.

RESULTS

Evaluators aged from 24 to 46 years old (33.8; SD: 7.32) demonstrated high computer literacy (6.36; SD:0.17); female (75 %), White (35 %), and clinical research coordinators (45 %). C2Q demonstrated high usability during the final cycle (2.26 out of 7 [lower scores are better], SD: 0.74). The number of unique usability issues decreased after each refinement. Fourteen subthemes emerged from three themes: seeking user goals, performing well-learned tasks, and determining what to do next.

CONCLUSIONS

The cognitive walkthrough with a think-aloud protocol informed iterative system refinement and demonstrated the usability of C2Q by clinical research staff. Key recommendations for system development and implementation include improving system intuitiveness and overall user experience through comprehensive consideration of user needs and requirements for task completion.

Theoretically Guided Iterative Design of the Sense2Quit App for Tobacco Cessation in Persons Living with HIV

The use of mobile health (mHealth technology) can be an effective intervention when considering chronic illnesses. Qualitative research methods were used to identify specific content and features for a mobile app for smoking cessation amongst people living with HIV (PWH). We conducted five focus group sessions followed by two Design Sessions with PWH who were or are currently chronic cigarette smokers. The first five groups focused on the perceived barriers and facilitators to smoking cessation amongst PWH. The two Design Sessions leveraged the findings from the focus group sessions and were used to determine the optimal features and user interface of a mobile app to support smoking cessation amongst PWH. Thematic analysis was conducted using the Health Belief Model and Fogg's Functional Triad. Seven themes emerged from our focus group sessions: history of smoking, triggers, consequences of quitting smoking, motivation to quit, messages to help quit, quitting strategies, and mental health-related challenges. Functional details of the app were identified during the Design Sessions and used to build a functional prototype.

Efficacy of an mHealth self-management intervention for persons living with HIV: the WiseApp randomized clinical trial

IMPORTANCE

Progression of HIV disease, the transmission of the disease, and premature deaths among persons living with HIV (PLWH) have been attributed foremost to poor adherence to HIV medications. mHealth tools can be used to improve antiretroviral therapy (ART) adherence in PLWH and have the potential to improve therapeutic success.

OBJECTIVE

To determine the efficacy of WiseApp, a user-centered design mHealth intervention to improve ART adherence and viral suppression in PLWH.

DESIGN, SETTING, AND PARTICIPANTS

A randomized (1:1) controlled efficacy trial of the WiseApp intervention arm (n = 99) versus an attention control intervention arm (n = 101) among persons living with HIV who reported poor adherence to their treatment regimen and living in New York City.

INTERVENTIONS

The WiseApp intervention includes the following components: testimonials of lived experiences, push-notification reminders, medication trackers, health surveys, chat rooms, and a "To-Do" list outlining tasks for the day. Both study arms also received the CleverCap pill bottle, with only the intervention group linking the pill bottle to WiseApp.

RESULTS

We found a significant improvement in ART adherence in the intervention arm compared to the attention control arm from day 1 (69.7% vs 48.3%, OR = 2.5, 95% CI 1.4-3.5, P = .002) to day 59 (51.2% vs 37.2%, OR = 1.77, 95% CI 1.0-1.6, P = .05) of the study period. From day 60 to 120, the intervention arm had higher adherence rates, but the difference was not significant. In the secondary analyses, no difference in change from baseline to 3 or 6 months between the 2 arms was observed for all secondary outcomes.

CONCLUSIONS

The WiseApp intervention initially improved ART adherence but did not have a sustained effect on outcomes.

Do correlates of white matter features differ between older men and women living with human immunodeficiency virus?

OBJECTIVE

Given estrogen's role in human immunodeficiency virus (HIV) disease progression and the higher rates of neurocognitive decline in affected women, the purpose of this study was to assess whether the relationship of white matter features and reproductive hormone levels differed between men versus women (sex as a moderator), controlling for selected cardiometabolic risk factors, HIV-related health indicators, and demographics in an aging population of persons living with HIV (PLWH).

METHODS

Older PLWH (50 y and older; 44 women and 35 men; mean ± SD age, 59.8 ± 0.6 y; 55.7% women; 72.2% non-Hispanic Black) participated in a cross-sectional study involving a fasting blood draw and a demographic survey (visit 1) and a magnetic resonance imaging scan (visit 2) to determine white matter volume and white matter hyperintensity (WMH) volume. Associations between reproductive hormones (follicle-stimulating hormone [FSH], estradiol, testosterone, dehydroepiandrosterone sulfate [DHEA-S]) and white matter features were assessed in linear regression models. Covariates were age, body mass index, hypertension, diabetes, dyslipidemia, current smoking status, CD4 count, and cranial size.

RESULTS

For white matter volume, a sexually dimorphic interaction was seen for DHEA-S (B = 21.23; P = 0.012) and observed for FSH (B = -22.97, P = 0.08) with a trend for significance after controlling for risk factors. In women, higher white matter volume was associated with higher DHEA-S (B = 13.89, P = 0.017) and lower FSH (B = 23.58, P = 0.01). No hormone associations were shown in men for white matter volume. For WMH volume, no significant interaction effects between sex and reproductive hormones were identified. For WMH, sex did not predict associations with reproductive hormones after controlling for risk factors.

CONCLUSIONS

Although sexually dimorphic interactions of reproductive hormones and total white matter volume were demonstrated, our study findings do not support a role for sex-based differences in reproductive hormones as predictive correlates of WMH in a small sample of older PLWH.

Understanding changes in mental health symptoms from young-old to old-old adults by sex using multiple-group latent transition analysis

Older adults are classified into three homogeneous groups: young-old (age 65-74), old-old (age 75-84), and oldest-old (age 85 and over). Mental health symptoms are likely to change over time, especially when older adults transition from one age group to another. Yet, little is known on changes in mental health symptoms as they transition to another age group, and if these changes differ by sex. This is a secondary data analysis using the longitudinal data from the National Social Life, Health, and Aging Project. A total of 1183 young-old adults at wave 1 was included. Mental health symptoms were depression, anxiety, loneliness, perceived stress, and happiness. Multiple-group latent transition analysis was conducted to model the transition probabilities of latent classes and to compare these differences between sex. Descriptive and inferential statistics were conducted to obtain demographic characteristics and to test for differences. Three latent classes were identified based on severity: class 1-mild, class 2-moderate, and class 3-severe. Regardless of sex, young-old adults remained in the same class from waves 1 to 2. However, they moved to a less severe group when transitioning into the old-old from waves 2 to 3. Statistically significant differences were found in their demographic characteristics among the latent classes. Older adults, when transitioning from young-old to old-old, are likely to transition to latent classes with less severe mental health symptoms in both sex. Clinicians need to provide a comprehensive assessment to all older adults, regardless of the severity of their mental health symptoms, to promote well-being.

A feasibility study of the use of HIV self-tests in young men who have sex with men

Studies on HIV self-testing (HIV-ST) have been limited to adults (age 18+). The study assessed use of HIV-ST among a diverse group of young men who have sex with men (YMSM) in the United States (US) and assessed differences in uptake by demographic characteristics and requirements for parental consent. This study demonstrated feasibility of HIV-ST for YMSM as young as 14 years of age, which suggests potential for increasing HIV testing in this young age group and promoting health equity.

A Systematic Review of Self-Management Interventions Conducted Across Global Settings for Depressive Symptoms in Persons with HIV

Depressive symptoms can affect health outcomes in people living with HIV (PLWH) including adherence to treatment and disease prognosis. Self-management interventions targeting depressive symptoms have been effective in preventing these negative sequelae of depressive symptoms. The processes of self-management include learning skills related to living with the illness needs, accessing resources to manage the illness, and coping with the illness. A systematic literature review was conducted to appraise and synthesize the current evidence of self-management interventions targeting depressive symptoms in PLWH. Following the PRISMA guidelines, an electronic search of 4 databases was conducted. Original studies written in English that used a randomized controlled trial design to test the effect of self-management intervention on depressive symptoms were included. Studies were selected that were published on/before April 19, 2022, thus yielding 13 relevant articles. Risk of bias was assessed using the NIH Quality Assessment Tool for Controlled Intervention Studies and narrative synthesis was used to synthesize the results. 40 to 755 participants were included in the studies, with each using various measures to assess depressive symptoms pre-and post-intervention, and timepoints for assessing depressive symptoms post-intervention varied. While 12 studies showed a significant reduction in depressive symptoms post-intervention, only 4 studies that used individual coaching or technology showed lower depressive symptoms in intervention groups in comparison to the control groups. This review can be used to inform scale-up and dissemination of these interventions to improve depressive symptoms in PLWH.

Homonegative Victimization and Perceived Stress among Adolescent Sexual Minority Males: The Attenuating Role of Peer and Family Support

PURPOSE

Research suggests social support may protect sexual minorities from the harmful effects of victimization that undermine mental and sexual health wellness; however, this relationship has been underexplored among a diverse youth population. We examined the association between lifetime homonegative victimization, perceived stress in the last month, and resilience factors among a diverse sample of adolescent sexual minority males.

METHODS

Data were collected between June 2018 and April 2020 as part of the MyPEEPS Mobile study, a multi-site randomized controlled trial evaluating the effectiveness of a mobile behavioral HIV prevention intervention for adolescents living in the U.S. We analyzed baseline survey data from 542 sexual minority males, aged 13-18 years. We used bivariate analyses to examine relationships among variables and multivariable linear regression models to determine if resilience factors attenuated the association between homonegative victimization and perceived stress.

RESULTS

Perceived stress was positively associated with younger age, internalized homophobia, experiencing verbal victimization, threats of being outed, and threats of physical violence. Relying on online friends for support and having good family relations both attenuated the relationship between verbal victimization and perceived stress. However, neither of these resilience factors significantly weakened the associations between perceived stress, threats of physical violence, and being outed.

CONCLUSION

Resilience factors, including peer and family support, may play an attenuating role in the relationship between homonegative victimization and perceived stress among adolescent sexual minority males.

Efficacy of MyPEEPS Mobile, an HIV Prevention Intervention Using Mobile Technology, on Reducing Sexual Risk Among Same-Sex Attracted Adolescent Males: A Randomized Clinical Trial

IMPORTANCE

HIV transmission rates in the United States have increased among men who have sex with men. However, there are no published randomized trials examining interventions to reduce sexual risk for HIV acquisition in males younger than 18 years.

OBJECTIVE

To determine the efficacy of MyPEEPS Mobile, a mobile-delivered HIV prevention intervention, to reduce sexual risk behavior in same-sex attracted young males.

DESIGN, SETTING, AND PARTICIPANTS

This was a national randomized clinical trial of the efficacy MyPEEPS Mobile vs a delayed intervention among males aged 13 to 18 years to prevent or reduce sexual risk for HIV acquisition. Study activities were completed through 4 study sites in Birmingham, Alabama; New York, New York; Seattle, Washington; and Chicago, Illinois. Study staff at each site met with participants in person or via video conferencing. Data were collected from June 1, 2018, to April 7, 2020, and analyzed from July to October 2021.

INTERVENTIONS

The MyPEEPS Mobile intervention contains 21 online psychoeducational and skill-building modules, which participants completed over a 3-month period. Participants randomized to the intervention group received access to MyPEEPS Mobile for the first 3 months, while those randomized to the delayed intervention group received access at their 9-month visit after data for the primary efficacy analysis had been collected.

MAIN OUTCOMES AND MEASURES

The self-reported primary outcome was change in the number of condomless anal sex acts between study conditions. Secondary outcomes were change in the number of sex partners, number of condomless anal sex partners, the number of sex acts while under the influence of substances, preexposure prophylactic uptake, nonoccupational postexposure prophylaxis use, and HIV and sexually transmitted infection testing.

RESULTS

In the analytic sample of 763 racially and ethnically diverse study participants, the mean (SD) age was 16.2 (1.4) years; 736 participants (97%) were male, 13 (2%) nonbinary; and 6 (1%) genderqueer; 158 (21%) were Black or African American, 311 (41%) were Hispanic or Latino, and 284 (37%) were White. Overall, 382 were randomized to the intervention group and 381 to the delayed intervention group. At 3-month follow-up, there was a significant reduction in the number of condomless anal sex acts in the intervention group compared with the delayed intervention group (incidence rate ratio [IRR], 0.56; 95% CI, 0.32-0.99); however, there was no significant difference between groups at 6 or 9 months. In subgroup analyses, the intervention effect was pronounced among Black non-Hispanic participants at 3-month follow-up (IRR, 0.19; 95% CI, 0.04-0.94) and 6-month follow-up (IRR, 0.15; 95% CI, 0.03-0.78) compared with the delayed intervention group. There were no significant differences in the change in the number of sex partners, number of condomless anal sex partners, the number of sex acts while under the influence of substances, preexposure prophylactic uptake, nonoccupational postexposure prophylaxis use, and HIV and sexually transmitted infection testing between the intervention and delayed intervention groups.

CONCLUSIONS AND RELEVANCE

In this study, the MyPEEPS Mobile intervention demonstrated a 44% overall reduction in condomless anal sex at 3-month follow-up compared with the delayed intervention group, but not at 6 or 9 months. To our knowledge, MyPEEPS Mobile is the first intervention to demonstrate evidence of short-term efficacy for reducing sexual risk among same-sex attracted young males.

Patient-centered mobile tuberculosis treatment support tools (TB-TSTs) to improve treatment adherence: A pilot randomized controlled trial exploring feasibility, acceptability and refinement needs

Background

Digital adherence technologies hold promise to improve patient-centered tuberculosis (TB) monitoring, yet few studies have incorporated direct adherence monitoring or assessed patients' experiences with these technologies. We explored acceptability, feasibility, and refinement needs of the TB Treatment Support Tools (TB-TSTs) intervention linking a mobile app, a urine drug metabolite test, and interactive communication with a treatment supporter.

Methods

This pilot study was a parallel-designed single-center randomized controlled trial with exit interviews. Newly diagnosed TB patients were randomized 1:1 using a treatment allocation button in the REDCap software preloaded with a random allocation sequence to usual care or usual care plus the TB-TSTs intervention from a respiratory medicine hospital in the province of Buenos Aires, Argentina and followed for 6-months. Due to the nature of the intervention, blinding to the group allocation could not be achieved for the recruiter or patients. The treatment outcome data extractor was blinded to the group allocation of the participants. Intervention participants used the app to report self-administering medication, potential side effects, submit photos of the urine test, and interact with a treatment supporter. Outcomes were feasibility, acceptability, and treatment outcomes.

Findings

Forty-two patients were enrolled and evenly assigned to each group. Intervention participants submitted 147·2±58 (mean, SD) medication self-administration and 144·5±55 side effect reports out of 180 and 47.5±38·4 photos of the urine test out of 77. Treatment success for usual care was 81% [17/21] and 95% [20/21] for the TB-TSTs intervention. Thirty-three themes were identified within the main categories of motivation, what worked, issues experienced, and recommendations. Participants (n=12) rated it as 'easy to use' (4.57/5), 'would highly recommend to others' (4·43/5) and reported that access to the treatment support was a critical component. Recommendations included adding an alarm, appointment reminders, and off-line functionality.

Interpretation

Findings suggest that the TB-TSTs intervention was feasible and acceptable and further refinement and testing is warranted.

A Smoking Cessation Mobile App for Persons Living With HIV: Preliminary Efficacy and Feasibility Study

BACKGROUND

The prevalence of smoking in the United States general population has gradually declined to the lowest rate ever recorded; however, this has not been true for persons with HIV.

OBJECTIVE

We conducted a pilot test to assess the feasibility and efficacy of the Lumme Quit Smoking mobile app and smartwatch combination with sensing capabilities to improve smoking cessation in persons with HIV.

METHODS

A total of 40 participants were enrolled in the study and randomly assigned 1:1 to the control arm, which received an 8-week supply of nicotine replacement therapy, a 30-minute smoking cessation counseling session, and weekly check-in calls with study staff, or to the intervention arm, which additionally received the Lumme Quit Smoking app and smartwatch.

RESULTS

Of the 40 participants enrolled, 37 completed the follow-up study assessments and 16 used the app every day during the 56-day period. During the 6-month recruitment and enrollment period, 122 people were screened for eligibility, with 67.2% (82/122) deemed ineligible. Smoking criteria and incompatible tech were the major reasons for ineligibility. There was no difference in the proportion of 7-day point prevalence abstinence by study arm and no significant decrease in exhaled carbon monoxide for the intervention and control arms separately. However, the average exhaled carbon monoxide decreased over time when analyzing both arms together (P=.02).

CONCLUSIONS

Results suggest excellent feasibility and acceptability of using a smoking sensor app among this smoking population. The knowledge gained from this research will enable the scientific community, clinicians, and community stakeholders to improve tobacco cessation outcomes for persons with HIV.

Predictors of Past-Year Health Care Utilization Among Young Men Who Have Sex with Men Using Andersen's Behavioral Model of Health Service Use

Purpose: This study examined factors associated with past-year health care utilization among young gay, bisexual, and other men who have sex with men (YMSM) using Andersen's behavioral model of health service use. Methods: From 2018 to 2020, 751 YMSM (aged 13-18) recruited online and offline for the MyPEEPS mHealth HIV prevention study completed an online survey. Hierarchical logistic regression models assessed associations between past-year health care utilization (i.e., routine checkup) and predisposing (parental education, race/ethnicity, age, and internalized homonegativity), enabling (health literacy, health care facility type, U.S. Census Divisions), and need factors (ever testing for HIV). Results: The sample included 31.8% Hispanic, 23.9% White, and 14.6% Black YMSM; median age was 16. Most (75%) reported past-year health care utilization, often from private doctor's offices (29.1%); 6% reported no regular source of care. In the final regression model, higher odds of past-year health care utilization were found for younger participants (age 13-14, adjusted odds ratio [AOR] = 1.91; 95% confidence interval [CI]: 1.07-3.43; age 15-16 AOR = 1.55; 95% CI: 1.04-2.30; reference: 17-18) and those with increasing health literacy (AOR = 1.71; 95% CI: 1.36-2.16). YMSM with lower parental education had lower odds of past-year health care utilization (AOR = 0.56; 95% CI: 0.38-0.84), as did those relying on urgent care facilities (AOR = 0.60; 95% CI: 0.41-0.87; reference: routine care facilities) and those who identified as Mixed/Other race (AOR = 0.50; 95% CI: 0.28-0.91; reference: White). Conclusions: Findings highlight opportunities to intervene in YMSM's health risk trajectory before age 17 to reduce drop-off in routine health care utilization. Interventions to improve routine health care utilization among YMSM may be strengthened by building resilience (e.g., health literacy) while removing barriers maintained through structural disadvantage, including equity in education. Clinical Trial Registration Number: NCT03167606.

Working status and seasonal meteorological conditions predict physical activity levels in people living with HIV

Little is known about how demographic, employment and meteorological factors impact physical activity. We conducted an analysis to explore these associations from participants (N = 447) from six cities in the United States and matched their activity data with abstracted local meteorological data from National Oceanic and Atmospheric Administration (NOAA) weather reports. Participants were purposively recruited in 3-month blocks, from December 2015 to October 2017, to reflect physical activity engagement across the seasons. We calculated total physical activity (minutes/week) based on 7-day physical activity recall. Mild correlations were observed between meteorological factors and correlated with lower physical activity. Participants were least active in autumn (Median = 220 min/week) and most active in spring (Median = 375 min/week). In addition to level of education and total hours of work, maximum temperature, relative humidity, heating degree day, precipitation and sunset time together explained 17.6% of variance in total physical activity. Programs assisting in employment for PLHIV and those that promote indoor physical activity during more strenuous seasons are needed. Additional research to better understand the selection, preferences, and impact of indoor environments on physical activity is warranted.

Combining human and machine intelligence for clinical trial eligibility querying

OBJECTIVE

To combine machine efficiency and human intelligence for converting complex clinical trial eligibility criteria text into cohort queries.

MATERIALS AND METHODS

Criteria2Query (C2Q) 2.0 was developed to enable real-time user intervention for criteria selection and simplification, parsing error correction, and concept mapping. The accuracy, precision, recall, and F1 score of enhanced modules for negation scope detection, temporal and value normalization were evaluated using a previously curated gold standard, the annotated eligibility criteria of 1010 COVID-19 clinical trials. The usability and usefulness were evaluated by 10 research coordinators in a task-oriented usability evaluation using 5 Alzheimer's disease trials. Data were collected by user interaction logging, a demographic questionnaire, the Health Information Technology Usability Evaluation Scale (Health-ITUES), and a feature-specific questionnaire.

RESULTS

The accuracies of negation scope detection, temporal and value normalization were 0.924, 0.916, and 0.966, respectively. C2Q 2.0 achieved a moderate usability score (3.84 out of 5) and a high learnability score (4.54 out of 5). On average, 9.9 modifications were made for a clinical study. Experienced researchers made more modifications than novice researchers. The most frequent modification was deletion (5.35 per study). Furthermore, the evaluators favored cohort queries resulting from modifications (score 4.1 out of 5) and the user engagement features (score 4.3 out of 5).

DISCUSSION AND CONCLUSION

Features to engage domain experts and to overcome the limitations in automated machine output are shown to be useful and user-friendly. We concluded that human-computer collaboration is key to improving the adoption and user-friendliness of natural language processing.

Uncontrolled HIV and inflammation is associated with intracranial saccular aneurysm presence

OBJECTIVE

To study biomarkers of inflammation in cerebrovascular disease, exploring modifiable and non-modifiable biochemical and clinical risk factors associated with the presence of intracranial saccular aneurysms (ISAs) in an HIV-positive cohort.

DESIGN

A cross-sectional community-based study was used to study blood biomarkers of inflammation as predictors of cerebrovascular disease, specifically the presence of ISAs in persons with HIV. Potential biochemical and clinical predictors of ISA presence were identified.

METHODS

Time of flight magnetic resonance angiography and magnetic resonance imaging data identified the presence of ISAs in an HIV-positive cohort. Quantitative assays for neuroinflammatory biomarkers were performed on plasma blood samples. Lasso regression models were used to identify neuroinflammatory biomarkers and clinical risk factors associated with ISAs.

RESULTS

Eight of 72 participants had radiographically identified ISAs. ISAs were more common in non-Hispanic black participants (18.5% vs. 0% presence in nonblack patients). Participants with well controlled HIV (defined as CD4+ count >200 cells/ml and undetectable viral load at time of magnetic resonance imaging) had lower odds of ISAs (odds ratio: 0.19, 95% confidence interval 0.05-0.79) independent of age, sex, ethnicity and vascular risk factors. Macrophage inflammatory protein-1 p, an HIV- suppressive factor detected in participant blood samples, was inversely associated with aneurysm presence.

CONCLUSION

Well controlled HIV is associated with fewer ISAs. The identification of non-modifiable and modifiable risk factors contributing to ISA formation may provide valuable insight to impact clinical practice and inform the pathophysiology underlying ISA formation.

Are State-Level HIV Testing Policies for Minors Associated With HIV Testing Behavior and Awareness of Home-Based HIV Testing in Young Men Who Have Sex With Men?

PURPOSE

The objective of this study was to determine whether state-level policies that restrict minors' access to confidential HIV testing without parental consent may suppress HIV testing in young men who have sex with men (YMSM) in the United States.

METHODS

Secondary data from a national HIV prevention trial among YMSM aged 13-17 years (N= 612) were analyzed to evaluate the association between living in a state with restrictive HIV testing policies for minors and HIV testing behavior, awareness of home-based HIV testing, and confidential interactions with a physician. Multilevel logistic regression models were adjusted for age, parents' education level, race, ethnicity, sexual orientation, being sexually experienced, and health literacy of medical forms and controlled for clustering by state. Age-stratified models by state-level age of consent for HIV testing and a subanalysis (including only sexually experienced participants) were also conducted.

RESULTS

Residing in a state with restrictive HIV testing policies was associated with the lack of awareness of home-based HIV testing (adjusted odds ratio [aOR]: 3.06; 95% confidence intervals [CI]: 1.49, 6.28). No significant associations were found for HIV testing behavior (aOR: 1.81; 95% CI: 0.85, 3.84), speaking privately with a physician (aOR: 1.00; 95% CI: 0.56, 1.79), or discussing confidentiality with a physician (aOR: 0.95; 95% CI: 0.52, 1.71) and HIV testing policies for minors. These results were consistent in both the age-stratified models and subanalysis.

DISCUSSION

HIV testing proportions among YMSM did not differ by state-level minor consent laws. However, YMSM living in states with restrictive policies on HIV testing for minors were less likely to be aware of home-based HIV testing.

Protocol for a pilot randomized controlled trial of a mobile health exercise intervention for older patients with myeloid neoplasms (GO-EXCAP 2)

INTRODUCTION

We have shown the Exercise for Cancer Patients (EXCAP©®) exercise program improved physical function and symptoms and reduced inflammatory markers in patients with cancer. However, adherence to exercise was lower in older adults compared to their younger counterparts. We then leveraged a mobile app to deliver EXCAP©® and adapted the intervention [Geriatric-Oncology (GO)-EXCAP] for older patients with myeloid neoplasms. In this pilot randomized trial, the primary goal is to determine effect sizes. We propose to assess the preliminary efficacy of GO-EXCAP compared to a behavioral placebo control on physical function, patient-reported outcomes (fatigue, mood, and quality of life), and inflammatory markers in 100 patients aged ≥60 years with myeloid neoplasms receiving outpatient chemotherapy.

METHODS

GO-EXCAP consists of the EXCAP©® exercise prescription (daily home-based progressive aerobic walking and resistance exercises with rated perceived exercise of 5-8), EXCAP©® kit (i.e., activity tracker, resistance bands, print manual, bag), a mobile app, and an in-person or virtual session with the exercise physiologist to deliver exercise prescription. The intervention will last for three cycles of chemotherapy (approximately 12 weeks). The primary outcome measure will be physical function (Short Physical Performance Battery). Secondary outcome measures include fatigue (Brief Fatigue Inventory), mood (Center for Epidemiologic Studies Depression Scale), and quality of life (Functional Assessment of Cancer Therapy-Leukemia). Exploratory outcome measures include inflammatory markers.

DISCUSSION

Older adults with myeloid neoplasms receiving outpatient chemotherapy serve as an ideal model for studying an individually tailored mobile health exercise intervention in vulnerable older patients receiving cancer treatments to prevent physical function decline and improve symptoms.

Smoking Cessation System for Preemptive Smoking Detection

Smoking cessation is a significant challenge for many people addicted to cigarettes and tobacco. Mobile health-related research into smoking cessation is primarily focused on mobile phone data collection either using self-reporting or sensor monitoring techniques. In the past 5 years with the increased popularity of smartwatch devices, research has been conducted to predict smoking movements associated with smoking behaviors based on accelerometer data analyzed from the internal sensors in a user's smartwatch. Previous smoking detection methods focused on classifying current user smoking behavior. For many users who are trying to quit smoking, this form of detection may be insufficient as the user has already relapsed. In this paper, we present a smoking cessation system utilizing a smartwatch and finger sensor that is capable of detecting pre-smoking activities to discourage users from future smoking behavior. Pre-smoking activities include grabbing a pack of cigarettes or lighting a cigarette and these activities are often immediately succeeded by smoking. Therefore, through accurate detection of pre-smoking activities, we can alert the user before they have relapsed. Our smoking cessation system combines data from a smartwatch for gross accelerometer and gyroscope information and a wearable finger sensor for detailed finger bend-angle information. We compare the results of a smartwatch-only system with a combined smartwatch and finger sensor system to illustrate the accuracy of each system. The combined smartwatch and finger sensor system performed at an 80.6% accuracy for the classification of pre-smoking activities compared to 47.0% accuracy of the smartwatch-only system.

Cognitive Function Characterization Using Electronic Health Records Notes

Cognitive impairment is a defining feature of neurological disorders such as Alzheimer's disease (AD), one of the leading causes of disability and mortality in the elderly population. Assessing cognitive impairment is important for diagnostic, clinical management, and research purposes. The Folstein Mini-Mental State Examination (MMSE) is the most common screening measure of cognitive function, yet this score is not consistently available in the electronic health records. We conducted a pilot study to extract frequently used concepts characterizing cognitive function from the clinical notes of AD patients in an Aging and Dementia clinical practice. Then we developed a model to infer the severity of cognitive impairment and created a subspecialized taxonomy for concepts associated with MMSE scores. We evaluated the taxonomy and the severity prediction model and presented example use cases of this model.

A systematic review of engagement in care and health care utilization among older adults living with HIV and non-communicable diseases

It is critical to understand health care engagement and utilization among older persons living with HIV (OPWH) who may have greater burden for non-communicable diseases. Following the PRISMA guidelines, a systematic review using 5 electronic databases was conducted to appraise and synthesize the current literature on the relationship of non-communicable diseases on engagement in care and health care utilization among OPWH. Original studies published in English between 2009 and 2019 were included, yielding 16 relevant articles. Overall, having co-morbid non-communicable diseases was associated with a decreased likelihood of initiating and adhering to ART. Being on ART and viral suppression were associated with better engagement in non-communicable disease care. Findings also suggest that an increasing number of co-morbidities is associated with higher health care utilization and financial burden. This review underscores the need for preventing and managing co-morbidities to enhance engagement in HIV care and that health care practitioners need to ensure that OPWH are engaged in care for both HIV and their co-morbid conditions by providing coordinated and integrated care.

Abstract WMP21: Blood Biomarkers Of Endothelial And Macrocytic Activation Are Associated With Brain White Matter Microstructure In People Living With Hiv On Antiretroviral Treatment

Objective: To identify associations between specific serum inflammatory markers and structural white matter integrity as measured on brain diffusion tensor imaging (DTI) in middle-aged people living with HIV (PLWH).

Methods: PLWH over 50 years of age residing in New York, NY participated in a cross-sectional study between January and July 2019. Demographic and magnetic resonance imaging data, along with blood samples, were collected. Least absolute shrinkage and selection operator (LASSO) regression was used to identify the most relevant variables associated with brain white matter fractional anisotropy (FA) and mean diffusivity (MD), among seventeen serum inflammatory markers, and control variables (listed in Table 1).

Results: A total of 85 PLWH were included in the analysis. Mean age (SD) was 60 (6) years, 48% were men and 78% non-Hispanic black. All were taking antiretroviral therapy at enrollment. Among them, 75% had CD4 count ≥200 cell/mm 3 and viral load <400 copies/mL near the time of their MRI scans. We observed that, as the penalty factor (λ) increased in the LASSO regression, vascular endothelial growth factor (VEGF) (β=-0.052), monocyte chemoattractant protein 1 (MCP-1) (β=-0.001) and macrophage inflammatory proteins 1α (MIP-1α) (β=-0.007) and 1β (MIP-1β) (β=-0.074) remained in the LASSO model for FA. Similarly, VEGF (β=1.01x10 -4 ), MIP-1α (β=3.67x10 -6 ) and MIP-1β (β=7.12x10 -5 ) remained in the LASSO model for MD (Table 1).

Conclusion: Prior research has linked VEGF to HIV-associated encephalopathy and MCP-1 to HIV-associated dementia, while both MIP-1α and MIP-1β have been associated with asymptomatic HIV infection. Our findings therefore may offer a mechanistic framework for those associations, indicating that chronic inflammation in the context of HIV infection may alter brain white matter microstructure. Such alterations may contribute to the development of HIV-associated central nervous system disorders.

Establishing a usability cut-point for the Health Information Technology Usability Evaluation Scale (Health-ITUES)

OBJECTIVE

The Health Information Technology Usability Evaluation Scale (Health-ITUES) is a validated and reliable instrument to evaluate usability of information technology (IT) tools. In this study, we aimed to establish the optimal cut-point of the Health-ITUES to identify usability of IT tools.

METHODS

Adult participants were recruited to a trial evaluating a mobile app for self-managing HIV. Participants completed the Health-ITUES at the 3- and 6-month follow-up. Health-ITUES is a 20-item questionnaire that assesses four subscales: impact, perceived usefulness, perceived ease of use, and user control. The total score ranged from 1 to 5 and a higher score indicates greater usability. App use was defined as the proportion of activities completed by participants in both study arms. The selection of an optimal cut-point involved a series of multiple linear regression models with 500 bootstrap replications to examine the relationship between the Health-ITUES total score and app use, controlling for potential covariates.

RESULTS

We included 158 participants; mean age was 49.7 years (SD 10.3), 71% were African American/Black, and 72% were non-Hispanic. Mean Health-ITUES total scores at 3 and 6 months were 4.39 (SD 0.75) and 4.43 (SD 0.75), respectively. App use completedby participants from baseline to the 3-month follow-up visits was 0.61 (SD 0.36, range 0-1.72) and from 3-month to the 6-month follow-up visits was 0.51 (SD 0.37). Participants who reported greater Health-ITUES total score completed more activities [β = 0.18, 95% Confidence Interval (CI) 0.10-0.27]. The optimal cut-point of 4.32 (95% CI: 4.25-4.56) yielded the lowest p-value to identify usability of IT tools.

CONCLUSIONS

In this study of adults with HIV, we identified an optimal cut-point of 4.32 on the Health-ITUES total score to define usability. Further studies are needed to validate this cut-point.

Validity and Reliability of the Korean Version of the Health Information Technology Usability Evaluation Scale: Psychometric Evaluation

Background

Rigorous development of mobile technologies requires the use of validated instruments to evaluate the usability of these tools, which has become more relevant with the expansion of these technologies. Although various usability evaluation tools have been developed, there are relatively few simple evaluation instruments that have been validated across diseases and languages in mobile health (mHealth) information technology for use in multiple diseases.

Objective

The purpose of this study is to validate the Korean version of the Health Information Technology Usability Evaluation Scale (Korean Health-ITUES) and assess its applicability for different health conditions.

Methods

To develop the Korean Health-ITUES, we used a validation process involving the following 3 steps: (1) customization of the Health-ITUES for menstrual symptoms, (2) translation of the Health-ITUES from English into Korean, and (3) examination of the reliability and validity of the instrument. The translation process adhered to the World Health Organization (WHO) guidelines for translation and back-translation, expert review, and reconciliation.

Results

The Korean Health-ITUES showed reliable internal consistency with Cronbach α=.951; meanwhile, factor loadings of the 20 items in the 4 subscales ranged from 0.416 to 0.892.

Conclusions

The Health-ITUES demonstrated reliability and validity for its use in assessing mHealth apps’ usability in young Korean women with menstrual discomfort. Given the strong psychometric properties of this tool in Korean and English and across 2 different health conditions, the Health-ITUES is a valid and reliable instrument for assessing the usability of mHealth apps. The Health-ITUES is also a valid instrument for evaluating mHealth technologies, which are widely used by patients to self-manage their health and by providers to improve health care delivery.

"If They Give Their Mind to HIV, They Don't Last as Long": An Explanatory Model of HIV Infection in a Limited-Resource Setting Informs Person-Centered Care

Explanatory models describe individuals’ perceptions of their illness experiences, which can guide culturally relevant care. We constructed an explanatory model of the experience of living with human immunodeficiency virus (HIV) in the Dominican Republic. Following qualitative descriptive methodology, we conducted interviews in Spanish using a semi-structured interview guide developed using Kleinman’s explanatory model framework. Two bilingual researchers coded interview transcripts following conventional content analysis. We used deductive codes from Kleinman’s framework and inductive codes external to the framework to construct the codebook. We arranged codes by shared meaning into categories and constructed themes that reflected shared findings from inductive categories and deductive codes. Twenty-six persons living with HIV participated. They provided rich descriptions of their experiences represented by four cross-cutting themes, which informed the explanatory model. By incorporating this in-depth understanding of patients’ illness experiences into care delivery, nurses can cultivate culturally meaningful and trusting patient-centered partnerships that improve health.
