Associations between alcohol and cigarette use and type 1 and 2 myocardial infarction among people with HIV.

OBJECTIVES: People with HIV have a higher risk of myocardial infarction (MI) than the general population, with a greater proportion of type 2 MI (T2MI) due to oxygen demand-supply mismatch compared with type 1 (T1MI) resulting from atherothrombotic plaque disruption. People living with HIV report a greater prevalence of cigarette and alcohol use than do the general population. Alcohol use and smoking as risk factors for MI by type are not well studied among people living with HIV. We examined longitudinal associations between smoking and alcohol use patterns and MI by type among people living with HIV. DESIGN AND METHODS: Using longitudinal data from the Centers for AIDS Research Network of Integrated Clinical Systems cohort, we conducted time-updated Cox proportional hazards models to determine the impact of smoking and alcohol consumption on adjudicated T1MI and T2MI. RESULTS: Among 13 506 people living with HIV, with a median 4 years of follow-up, we observed 177 T1MI and 141 T2MI. Current smoking was associated with a 60% increase in risk of both T1MI and T2MI. In addition, every cigarette smoked per day was associated with a 4% increase in risk of T1MI, with a suggestive, but not significant, 2% increase for T2MI. Cigarette use had a greater impact on T1MI for men than for women and on T2MI for women than for men. Increasing alcohol use was associated with a lower risk of T1MI but not T2MI. Frequency of heavy episodic alcohol use was not associated with MI. CONCLUSIONS: Our findings reinforce the prioritization of smoking reduction, even without cessation, and cessation among people living with HIV for MI prevention and highlight the different impacts on MI type by gender.

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

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

Tobacco smoking and binge alcohol use are associated with incident venous thromboembolism in an HIV cohort.

BACKGROUND: People with HIV (PWH) are at increased risk of cardiovascular comorbidities and substance use is a potential predisposing factor. We evaluated associations of tobacco smoking and alcohol use with venous thromboembolism (VTE) in PWH. METHODS: We assessed incident, centrally adjudicated VTE among 12 957 PWH within the Centers for AIDS Research Network of Integrated Clinical Systems (CNICS) cohort between January 2009 and December 2018. Using separate Cox proportional hazards models, we evaluated associations of time-updated alcohol and cigarette use with VTE, adjusting for demographic and clinical characteristics. Smoking was evaluated as pack-years and never, former, or current use with current cigarettes per day. Alcohol use was parameterized using categorical and continuous alcohol use score, frequency of use, and binge frequency. RESULTS: During a median of 3.6 years of follow-up, 213 PWH developed a VTE. One-third of PWH reported binge drinking and 40% reported currently smoking. In adjusted analyses, risk of VTE was increased among both current (HR: 1.44, 95% CI: 1.02-2.03) and former (HR: 1.44, 95% CI: 0.99-2.07) smokers compared to PWH who never smoked. Additionally, total pack-years among ever-smokers (HR: 1.10 per 5 pack-years; 95% CI: 1.03-1.18) was associated with incident VTE in a dose-dependent manner. Frequency of binge drinking was associated with incident VTE (HR: 1.30 per 7 days/month, 95% CI: 1.11-1.52); however, alcohol use frequency was not. Severity of alcohol use was not significantly associated with VTE. CONCLUSIONS: Current smoking and pack-year smoking history were dose-dependently associated with incident VTE among PWH in CNICS. Binge drinking was also associated with VTE. Interventions for smoking and binge drinking may decrease VTE risk among PWH.

Genetic architecture of cardiometabolic risks in people living with HIV.

BACKGROUND: Advances in antiretroviral therapies have greatly improved the survival of people living with human immunodeficiency virus (HIV) infection (PLWH); yet, PLWH have a higher risk of cardiovascular disease than those without HIV. While numerous genetic loci have been linked to cardiometabolic risk in the general population, genetic predictors of the excessive risk in PLWH are largely unknown. METHODS: We screened for common and HIV-specific genetic variants associated with variation in lipid levels in 6284 PLWH (3095 European Americans [EA] and 3189 African Americans [AA]), from the Centers for AIDS Research Network of Integrated Clinical Systems cohort. Genetic hits found exclusively in the PLWH cohort were tested for association with other traits. We then assessed the predictive value of a series of polygenic risk scores (PRS) recapitulating the genetic burden for lipid levels, type 2 diabetes (T2D), and myocardial infarction (MI) in EA and AA PLWH. RESULTS: We confirmed the impact of previously reported lipid-related susceptibility loci in PLWH. Furthermore, we identified PLWH-specific variants in genes involved in immune cell regulation and previously linked to HIV control, body composition, smoking, and alcohol consumption. Moreover, PLWH at the top of European-based PRS for T2D distribution demonstrated a > 2-fold increased risk of T2D compared to the remaining 95% in EA PLWH but to a much lesser degree in AA. Importantly, while PRS for MI was not predictive of MI risk in AA PLWH, multiethnic PRS significantly improved risk stratification for T2D and MI. CONCLUSIONS: Our findings suggest that genetic loci involved in the regulation of the immune system and predisposition to risky behaviors contribute to dyslipidemia in the presence of HIV infection. Moreover, we demonstrate the utility of the European-based and multiethnic PRS for stratification of PLWH at a high risk of cardiometabolic diseases who may benefit from preventive therapies.

Assessment of an adolescent-girl-focused nutritional educational intervention within a girls' empowerment programme: a cluster randomised evaluation in Zambia.

OBJECTIVE: Adolescent girls are at risk for both macro- and micronutrient deficiencies affecting growth, maternal and child health. This study assessed the impact of an adolescent-girl-tailored nutritional education curriculum on nutritional outcomes, including knowledge, dietary behaviour, anthropometry and anaemia. DESIGN: A cluster-randomised evaluation was conducted with two study arms: girls in mentor-led weekly girls' groups receiving sexual and reproductive health and life-skills training assigned to an age-appropriate nutritional curriculum and control girls in the weekly girls' groups without the nutritional education. The primary analysis was intent-to-treat (ITT) generalised least squares regression. Secondary analysis using two-stage, instrumental-variables estimation was also conducted. SETTING: The intervention and evaluation were conducted in urban and rural areas across four of ten provinces in Zambia. PARTICIPANTS: In total, 2660 girl adolescents aged 10-19 years were interviewed in 2013 (baseline) and annually through 2017. RESULTS: ITT results indicate that exposure to the nutritional educational programme did not meaningfully change outcomes for adolescents or their children. Intervention adolescents were no more likely to correctly identify healthy foods (P = 0·51) or proper infant-feeding practices (P = 0·92); were no less likely to be stunted (P = 0·30) or underweight (P = 0·87) and no less likely to be anaemic (P = 0·38). Outcomes for children of intervention participants were not improved, including being breastfed (P = 0·42), stunted (P = 0·21), wasted (P = 0·77) or anaemic (P = 0·51). CONCLUSIONS: Even a high-quality nutritional educational intervention tailored to adolescents within an empowerment programme does not assure improved nutritional outcomes; adolescent preferences, resource control and household dynamics require consideration in the context of nutritional educational programmes.

A Randomized Internet-Based Pilot Feasibility and Planning Study of Cherry Extract and Diet Modification in Gout.

OBJECTIVE: The aim of this study was to conduct a 9-month pilot Internet randomized controlled trial (RCT) of cherry extract and diet modification in gout to assess the feasibility of an Internet study and obtain effect estimates. METHODS: After providing online informed consent in response to Internet advertisements and social media or clinic flyers, 84 people with physician-confirmed gout were randomized to either cherry extract 3,600 mg/d (n = 41) or dietitian-assisted diet modification for gout (n = 43). All study outcomes were collected via Internet and phone calls. The primary objective was the feasibility of an Internet study, and secondary objectives were to obtain effect estimates for gout flares, functional ability assessed with the Health Assessment Questionnaire (HAQ), and adverse events (AEs) for future trials. RESULTS: Of the 84 people randomized, overall completion rates were more than 80% for most study procedures up to 6 months and similar for the 2 active comparators. Improvements were seen in gout flares and HAQ scores in cherry extract and diet modification groups at 9 months compared with baseline: gout flares per month, 0.22 versus 0.36 (p = 0.049) and 0.28 versus 0.31 (p = 0.76); proportion with any gout flare, 56% versus 98% (p < 0.0001) and 65% versus 98% (p = 0.0002); and mean ± standard deviation HAQ score, 0.28 ± 0.54 versus 0.55 ± 0.68 (p = 0.001) and 0.23 ± 0.40 versus 0.48 ± 0.61 (p = 0.06), respectively. Any AEs and gastrointestinal symptoms/AEs at 9 months in cherry extract and diet modification groups were 3% versus 0% and 28% versus 27%, respectively. CONCLUSIONS: An Internet gout RCT is feasible for nonpharmacological gout treatments. A hypothesis-testing, large Internet RCT of cherry extract versus placebo is needed.

Patient-Centered Outcomes and Key Study Procedure Finalization in the Pilot Feasibility Gout Randomized Trial: Comparative Feasibility Study in GOUt, CHerry Extract Versus Diet Modification (Mini-GOUCH).

OBJECTIVE: The aim of this study was to report patient-centered outcomes and finalization of key study procedures from a 9-month pilot internet randomized controlled trial of cherry extract versus diet modification. METHODS: We randomized 84 people with physician-confirmed gout in an internet study to cherry extract (n = 41) or dietitian-assisted diet modification for gout (n = 43). All study outcomes were collected via internet and phone calls. We finalized key study procedures. We assessed acceptability and feasibility of the intervention and satisfaction with study website. RESULTS: Study participant satisfaction with the intervention was high. The intervention was perceived as easy, enjoyable, understandable, and helpful (scores 65-88 for all; higher = better). The amount of time spent for the study was acceptable. Participant satisfaction with website interaction and content was very high; 85% or more were moderately to extremely satisfied. Significantly lower total calories, total carbohydrate, and saturated fat intake were noted at 6 months in the diet modification versus cherry extract group; differences were insignificant at 9 months. Six of the 8 Health Assessment Questionnaire sections/domains improved significantly from baseline to 9 months in cherry extract versus 2 Health Assessment Questionnaire sections/domains in the diet modification group. Key study procedures were finalized for a future trial, including an internet diet assessment tool, gout flare assessment, provider confirmation of gout diagnosis, patient reporting of classification criteria, and centralized laboratory-assisted serum urate testing. CONCLUSIONS: High patient acceptability and feasibility of study/intervention and finalization of key study procedures indicate that hypothesis-testing internet gout trials of cherry extract and/or diet modification can be conducted in the future.

Physical Activity Intensity is Associated with Symptom Distress in the CNICS Cohort.

Symptom distress remains a challenging aspect of living with HIV. Physical activity is a promising symptom management strategy, but its effect on symptom distress has not been examined in a large, longitudinal HIV-infected cohort. We hypothesized that higher physical activity intensity would be associated with reduced symptom distress. We included 5370 people living with HIV (PLHIV) who completed patient-reported assessments of symptom distress, physical activity, alcohol and substance use, and HIV medication adherence between 2005 and 2016. The most frequent and burdensome symptoms were fatigue (reported by 56%), insomnia (50%), pain (46%), sadness (45%), and anxiety (45%), with women experiencing more symptoms and more burdensome symptoms than men. After adjusting for age, sex, race, time, HIV medication adherence, alcohol and substance use, site, and HIV RNA, greater physical activity intensity was associated with lower symptom intensity. Although individual symptoms may be a barrier to physical activity (e.g. pain), the consistent association between symptoms with physical activity suggests that more intense physical activity could mitigate symptoms experienced by PLHIV.

Metabolic Complications and Glucose Metabolism in HIV Infection: A Review of the Evidence.

HIV infection and antiretroviral therapy (ART) use are associated with perturbations in glucose and lipid metabolism. Increasing incidence of diabetes, cardiovascular disease, and obesity highlights the need for early identification and treatment of metabolic dysfunction. Newer ART regimens are less toxic for cellular function and metabolism but have failed to completely eliminate metabolic dysfunction with HIV infection. Additional factors, including viral-host interactions, diet, physical activity, non-ART medications, and aging may further contribute to metabolic disease risk in the HIV setting. We summarize the recent literature regarding the impact on metabolic function of HIV infection, ART, and pharmaceutical or lifestyle prescriptions.

Diabetes Connect: African American Women's Perceptions of the Community Health Worker Model for Diabetes Care.

Community health worker (CHW) interventions have potential to improve diabetes outcomes and reduce health disparities. However, few studies have explored patient perspectives of peer-delivered diabetes programs. The purpose of this qualitative study is to investigate possible benefits as well as risks of CHW-delivered peer support for diabetes from the perspectives of African American women living with type 2 diabetes in Jefferson County, Alabama. Four ninety-minute focus groups were conducted by a trained moderator with a written guide to facilitate discussion on the topic of CHWs and diabetes management. Participants were recruited from the diabetes education database at a safety-net hospital. Two independent reviewers performed content analysis to identify major themes using a combined deductive-inductive approach. There were 25 participants. Mean years with diabetes was 11.2 (range 6 months to 42 years). Participants were knowledgeable about methods for self-management but reported limited resources and stress as major barriers. Preferred CHW roles included liaison to the healthcare system and easily accessible information source. Participants preferred that the CHW be knowledgeable and have personal experience managing their own diabetes or assisting a family member with diabetes. Concerns regarding the CHW-model were possible breaches of confidentiality and privacy. The self-management strategies and barriers to management identified by participants were reflected in their preferred CHW roles and traits. These results suggest that African American women with diabetes in Alabama would support peer-led diabetes education that is community-based and socially and emotionally supportive.

Metabolic consequences of HIV: pathogenic insights.

With the advances in antiretroviral therapy (ART), HIV infection has been transformed into a chronic medical condition that can be effectively managed like diabetes or hypertension. For HIV care providers, the focus of care for many patients has shifted from prevention of opportunistic infection and AIDS-related conditions to age-related cardiometabolic comorbidities, including cardiovascular disease, diabetes, obesity, and frailty. Numerous reports have highlighted that these diseases are occurring at an earlier age among HIV-infected persons. However, there is an ongoing debate regarding the role of HIV infection, ART, and other factors that may underlie the accelerated occurrence of these diseases. Herein, we review the epidemiology of the US HIV epidemic with regards to several metabolic comorbidities and address mechanisms that likely contribute to the current nature of HIV disease.

Body mass index, depression, and condom use among HIV-infected men who have sex with men: a longitudinal moderation analysis.

Findings have been inconsistent regarding the association of obesity and sexual risk behaviors. The purpose of the current study was to assess the prospective nature of body mass index (BMI), depression, and their interaction in predicting condom use during anal intercourse among HIV-infected men who have sex with men (MSM). The sample (N = 490) was obtained from a large, HIV clinical cohort from four sites across the U.S. The following inclusion criteria were employed: identification as MSM and had completed at least one wave of patient-reported measures (e.g., depression, as measured by the PHQ-9) in the clinical cohort study. Longitudinal linear mixed-effects modeling revealed a significant BMI by depression interaction. Depressive symptoms were predictive of less frequent condom use for obese but not overweight men. Analogous results were found in regard to comparisons between normal weight and overweight men. Obesity, in the context of depression, is a risk factor for unprotected anal intercourse among HIV-infected MSM. Cognitive behavioral interventions to reduce HIV transmission risk behaviors among HIV-infected MSM should adopt an integrated perspective, combining sexual risk reduction with treatment for depression and body-related concerns.

Telehealth Behavioral Intervention for Chronic Disease Self-Management in Adults With Physical Disabilities (My Health, My Life, My Way): Protocol for Intervention Fidelity and Dashboard Design for a Randomized Controlled Trial.

BACKGROUND: Individuals with physical disabilities experience higher rates of chronic health conditions than individuals without physical disabilities. Self-management programs that use health coaching are effective at eliciting health behavior change in health outcomes such as goal setting, adherence, and health care use. Additionally, web-based resources such as telehealth-based technologies, including SMSS text messaging, web-based applications, and educational multimedia content, can complement health coaching to improve health-related behaviors and the use of health services. The complexity of studies using these resources requires a fidelity protocol to ensure that health behavior studies are administered properly. OBJECTIVE: The My Health, My Life, My Way fidelity protocol provides methods, strategies, and procedures of a multifaceted telehealth program for individuals with permanent physical disabilities and chronic health conditions. This health behavior study is a randomized controlled trial with four study arms: (1) scheduled coaching calls with gamified rewards, (2) no scheduled coaching calls with gamified rewards, (3) scheduled coaching calls with fixed rewards, and (4) no scheduled coaching calls with fixed rewards. To guide the fidelity protocol developed, we used the National Institutes of Health Behavior Change Consortium framework (NIH BCC). METHODS: The fidelity intervention protocol was developed by using the 5 primary domains provided by the NIH BCC: study design, provider training, treatment delivery, treatment receipt, and enactment of treatment skills. Following the NIH BCC guidelines and implementing social cognitive theory, this study is designed to ensure that all study arms receive equal treatment across conditions and groups. Health coaches and providers will be trained to deliver consistent health coaching, and thus participants will receive appropriate attention. Educational content will be developed to account for health literacy and comprehension of the material. Multiple fidelity intervention steps such as coaching call logs, regular content review, and participant progress monitoring will translate to participants using the skills learned in their daily lives. Different monitoring steps will be implemented to minimize differences among the 4 treatment groups. RESULTS: My Health, My Life, My Way has been approved by the institutional review board and will begin enrollment in January 2024 and end in December 2024, with results reported in early 2025. CONCLUSIONS: Intervention fidelity protocols are necessary to ensure that health behavior change studies can be implemented in larger real-world settings. The My Health, My Life, My Way fidelity protocol has used the guidelines by the NIH BCC to administer a telehealth intervention combined with health coaching for individuals with physical disabilities and chronic health conditions. This fidelity protocol can be used as a complementary resource for other researchers who conduct similar research using telehealth technologies and health coaching in real-world settings.

Association of Integrase Strand Transfer Inhibitor-Based Antiretroviral Therapy with Blood Pressure and Sustained Hypertension in People with HIV.

BACKGROUND: Integrase strand transfer inhibitors (INSTI) are a commonly used antiretroviral therapy (ART) class in people with human immunodeficiency virus (HIV) and associated with weight gain. We studied the association of INSTI-based ART with systolic and diastolic blood pressure (SBP and DBP). METHODS: We recruited 50 people taking INSTI-based ART and 40 people taking non-INSTI-based ART with HIV and hypertension from the University of Alabama at Birmingham HIV clinic. Office BP was measured unattended using an automated (AOBP) device. Awake, asleep and 24-hour BP were measured through ambulatory BP monitoring. Among participants with SBP ≥130 mmHg or DBP≥80 mmHg on AOBP, sustained hypertension was defined as awake SBP≥130 mmHg or DBP≥80 mmHg. RESULTS: Mean SBP and DBP was higher among participants taking INSTI-based versus non-INSTI-based ART (AOBP-SBP/DBP: 144.7/83.8 versus 135.3/79.3 mmHg; awake-SBP/DBP: 143.2/80.9 versus 133.4/76.3 mmHg; asleep-SBP/DBP: 133.3/72.9 versus 120.3/65.4 mmHg; 24-hour-SBP/DBP: 140.4/78.7 versus 130.0/73.7 mmHg). After multivariable adjustment, AOBP, awake, asleep and 24-hour SBP was 12.5 (95%CI 5.0-20.1), 9.8 (95%CI 3.6-16.0), 10.4 (95%CI 2.0-18.9), and 9.8 (95%CI 4.2-15.4) mmHg higher among those taking INSTI-based versus non-INSTI-based ART, respectively. AOBP, awake, asleep and 24-hour DBP was 7.5 (95%CI 0.3-14.6), 6.1 (95%CI 0.3-11.8), 7.5 (95%CI 1.4-13.6), and 6.1 (95%CI 0.9-11.3) mmHg higher among those taking INSTI-based versus non-INSTI-based ART after multivariable adjustment. All participants had SBP ≥130 mmHg or DBP≥80 mmHg on AOBP and 97.9% and 65.7% of participants taking INSTI-based and non-INSTI-based ART had sustained hypertension, respectively. CONCLUSION: INSTI-based ART was associated with higher SBP and DBP than non-INSTI-based ART.

Brief Report: Relationship Between Adiposity and Biomarkers of Aging and Frailty Among Adults Aging With HIV.

BACKGROUND: This study examined the relationships among adiposity, handgrip, physical function, inflammation (ie, senescence-associated secretory phenotype chemokines as biomarkers of aging and frailty), and sex hormones in aging people with HIV. METHODS: This cross-sectional exploratory study included 150 people with HIV aged ≥40 years (67.3% of participants were male). Our measures included (1) body mass index and waist circumference as measures of adiposity; (2) handgrip as a measure of muscle strength; (3) short physical performance battery as a measure of physical function; (4) interleukin-6, tumor necrosis factor alpha receptor II, high sensitivity C-reactive protein, C-X-C motif chemokine 10, and C-X3-C motif chemokine ligand 1 also known as fractalkine as senescence-associated secretory phenotype chemokines; and (5) free testosterone, estradiol, sex hormone-binding globulin, and dehydroepiandrosterone as sex hormones. Quantile regression analyses were used to identify relationships among inflammatory markers and hormones with age, adiposity, handgrip, and physical function. RESULTS: Overall, 74% (n = 111) of participants were classified as overweight or obese and 53.3% (n = 80) presented with abdominal obesity. After controlling for age and sex, body mass index was positively associated with estradiol (ß = 0.043, P < 0.01), and waist circumference was positively associated with high sensitivity C-reactive protein (ß = 2.151, P < 0.01). After controlling for sex, age was positively associated with C-X-C motif chemokine 10 (ß = 0.024, P = 0.03) and tumor necrosis factor alpha receptor II (ß = 2.205, P = 0.01). After controlling for age and sex, short physical performance battery was negatively associated with dehydroepiandrosterone (ß = -0.004, P = 0.01); no statistically significant associations were observed for handgrip. CONCLUSION: Adiposity levels and aging were associated with inflammation (ie, C-X-C motif chemokine 10, tumor necrosis factor alpha receptor II, and high sensitivity C-reactive protein) among people with HIV aged 40 years and older.

Weight loss associated with semaglutide treatment among people with HIV.

OBJECTIVE: There is limited real-world evidence about the effectiveness of semaglutide for weight loss among people with HIV (PWH). We aimed to investigate weight change in a US cohort of PWH who initiated semaglutide treatment. DESIGN: Observational study using the Centers for AIDS Research Network of Integrated Clinical Systems (CNICS) cohort. METHODS: We identified adult PWH who initiated semaglutide between 2018 and 2022 and with at least two weight measurements. The primary outcome was within-person bodyweight change in kilograms at 1 year. The secondary outcome was within-person Hemoglobin A1c percentage (HbA1c) change. Both outcomes were estimated using multivariable linear mixed model. RESULTS: In total, 222 new users of semaglutide met inclusion criteria. Mean follow-up was 1.1 years. Approximately 75% of new semaglutide users were men, and at baseline, mean age was 53 years [standard deviation (SD): 10], average weight was 108 kg (SD: 23), mean BMI was 35.5 kg/m 2 , mean HbA1c was 7.7% and 77% had clinically recognized diabetes. At baseline, 97% were on ART and 89% were virally suppressed (viral load < 50 copies/ml). In the adjusted mixed model analysis, treatment with semaglutide was associated with an average weight loss of 6.47 kg at 1 year (95% CI -7.67 to -5.18) and with a reduction in HbA1c of 1.07% at 1 year (95% CI -1.64 to -0.50) among the 157 PWH with a postindex HbA1c value. CONCLUSION: Semaglutide was associated with significant weight loss and HbA1c reduction among PWH, comparable to results of previous studies from the general population.

Differences in internalized HIV stigma across subpopulations of people with HIV in care across the United States.

BACKGROUND: Few studies have examined which subgroups of people with HIV (PWH) carry the greatest burden of internalized HIV stigma (IHS), which may be important to care provision and interventions. METHODS: PWH in the CFAR Network of Integrated Clinical Systems (CNICS) longitudinal, US-based, multisite, clinical care cohort completed tablet-based assessments during clinic visits including a four-item, Likert scale (low 1-5 high), IHS instrument. Associations between sociodemographic characteristics and IHS scores were assessed in adjusted linear regression models. RESULTS: Twelve thousand six hundred and fifty-six PWH completed the IHS assessment at least once from February 2016 to November 2022, providing 28 559 IHS assessments. At baseline IHS assessment, the mean age was 49 years, 41% reported White, 38% Black/African American, and 16% Latine race/ethnicity, and 80% were cisgender men. The mean IHS score was 2.04, with all subgroups represented among those endorsing IHS. In regression analyses, younger PWH and those in care fewer years had higher IHS scores. In addition, cisgender women vs. cisgender men, PWH residing in the West vs. the Southeast, and those with sexual identities other than gay/lesbian had higher IHS scores. Compared with White-identifying PWH, those who identified with Black/African American or Latine race/ethnicity had lower IHS scores. Age stratification revealed patterns related to age category, including specific age-related differences by gender, geographic region and race/ethnicity. DISCUSSION: IHS is prevalent among PWH, with differential burden by subgroups of PWH. These findings highlight the benefits of routine screening for IHS and suggest the need for targeting/tailoring interventions to reduce IHS among PWH.

Venous Thromboembolism Among People With HIV: Design, Implementation, and Findings of a Centralized Adjudication System in Clinical Care Sites Across the United States.

BACKGROUND: People with HIV (PWH) are at increased risk for venous thromboembolism (VTE). We conducted this study to characterize VTE including provoking factors among PWH in the current treatment era. METHODS: We included PWH with VTE between 2010 and 2020 at 6 sites in the CFAR Network of Integrated Clinical Systems cohort. We ascertained for possible VTE using diagnosis, VTE-related imaging, and VTE-related procedure codes, followed by centralized adjudication of primary data by expert physician reviewers. We evaluated sensitivity and positive predictive value of VTE ascertainment approaches. VTEs were classified by type and anatomic location. Reviewers identified provoking factors such as hospitalizations, infections, and other potential predisposing factors such as smoking. RESULTS: We identified 557 PWH with adjudicated VTE: 239 (43%) had pulmonary embolism with or without deep venous thrombosis, and 318 (57%) had deep venous thrombosis alone. Ascertainment with clinical diagnoses alone missed 6% of VTEs identified with multiple ascertainment approaches. DVTs not associated with intravenous lines were most often in the proximal lower extremities. Among PWH with VTE, common provoking factors included recent hospitalization (n = 134, 42%), infection (n = 133, 42%), and immobilization/bed rest (n = 78, 25%). Only 57 (10%) PWH had no provoking factor identified. Smoking (46%), HIV viremia (27%), and injection drug use (22%) were also common. CONCLUSIONS: We conducted a robust adjudication process that demonstrated the benefits of multiple ascertainment approaches followed by adjudication. Provoked VTEs were more common than unprovoked events. Nontraditional and modifiable potential predisposing factors such as viremia and smoking were common.

Evaluating the Sick Quitting Hypothesis for Frailty Status and Reducing Alcohol Use Among People With HIV in a Longitudinal Clinical Cohort Study.

ABSTRACT: "Sick quitting," a phenomenon describing reductions in alcohol consumption following poor health, may explain observations that alcohol appears protective for frailty risk. We examined associations between frailty and reductions in drinking frequency among people with HIV (PWH). At six Centers for AIDS Research Network of Integrated Clinical Systems (CNICS) sites between January 2012 and August 2021, we assessed whether frailty, measured through validated modified frailty phenotype, precedes reductions in drinking frequency. We associated time-updated frailty with quitting and reducing frequency of any drinking and heavy episodic drinking (HED), adjusted for demographic and clinical characteristics in Cox models. Among 5,654 PWH reporting drinking, 60% reported >monthly drinking and 18% reported ≥monthly HED. Over an average of 5.4 years, frail PWH had greater probabilities of quitting (HR: 1.56, 95% confidence interval [95% CI] [1.13-2.15]) and reducing (HR: 1.35, 95% CI [1.13-1.62]) drinking frequency, as well as reducing HED frequency (HR: 1.58, 95% CI [1.20-2.09]) versus robust PWH. Sick quitting likely confounds the association between alcohol use and frailty risk, requiring investigation for control.
