RESUMEN

Little is known about HIV medication concealment behaviors and the effect of medication concealment on antiretroviral therapy (ART) adherence among people with HIV (PWH). This study aims to (1) to describe medication concealment behaviors and factors associated with these behaviors, and (2) assess the association between medication concealment and suboptimal ART adherence. The Florida Cohort Study enrolled adult PWH from community-based clinics around the state from October 2020 to September 2022 (n = 416, 62% aged 50+, 56% male, 44% non-Hispanic Black, 18% Hispanic). Participants responded to questions about sociodemographics, stigma, ART adherence (≥ 85%), symptoms of depression, social networks and disclosure to their networks, and actions to conceal ART to avoid inadvertent disclosure of their HIV status. Analyses were conducted using multivariable logistic regressions models. The most common concealment behavior was hiding ART while having guests over (32%), followed by removing ART labels (26%), and putting ART into a different bottle (16%). Overall, 43% reported ≥ 1 behavior. In multivariable models, depressive symptoms, incomplete disclosure of HIV to close social networks, and not having a close social network were associated with ART concealment. After adjusting for risk factors for suboptimal ART adherence, endorsing hiding medication while having guests was associated with suboptimal ART adherence (aOR 2.87, 95% CI 1.15-7.55). Taking any action and other individual behaviors were not associated. ART concealment behaviors were common but did not consistently negatively influence adherence when accounting for other factors. PWH may want to receive ART medications in ways that ensure privacy and reduce the risk of inadvertent disclosure.

RESUMEN

Long-acting injectable (LAI) antiretroviral therapy (ART) is available to people with HIV (PWH), but it is unknown which PWH prefer this option. Using the Andersen Behavioral Model this study identifies characteristics of PWH with greater preference for LAI ART. Cross-sectional data from the Florida Cohort, which enrolled adult PWH from community-based clinics included information on predisposing (demographics), enabling (transportation, income), and need (ART adherence <90%) factors. ART preference was assessed via a single question (prefer pills, quarterly LAI, or no preference). Confounder-adjusted multinomial logistic regressions compared those who preferred pills to the other preference options, with covariates identified using directed acyclic graphs. Overall, 314 participants responded (40% non-Hispanic Black, 62% assigned male, 63% aged 50+). Most (63%) preferred the hypothetical LAI, 23% preferred pills, and 14% had no preference. PWH with access to a car (aRRR 1.97 95%CI 1.05-3.71), higher income (aRRR 2.55 95%CI 1.04-6.25), and suboptimal ART adherence (aRRR 7.41 95% CI 1.52-36.23) were more likely to prefer the LAI, while those who reported having no social network were less likely to prefer the LAI (aRRR 0.32 95% CI 0.11-0.88). Overall LAI interest was high, with greater preference associated with enabling and need factors.

RESUMEN

BACKGROUND: Imported cerebral malaria (CM) cases in non-endemic areas are often misdiagnosed, which delays treatment. Post-malaria neurological syndrome (PMNS) after recovery from severe malaria can also complicate diagnosis. CASE: We report an imported malaria case from West Africa with two sequential episodes with neurological syndromes within about a month. The first episode was diagnosed as CM with microscopy-positive Plasmodium falciparum infection. The second episode, occurring a month after the recovery from the first CM episode, was consistent with PMNS, since malaria parasites were not detected by microscopy in peripheral blood smears. However, this diagnosis was complicated by the detection of Plasmodium vivax in peripheral blood by PCR, suggesting a potential cause of the second episode by P. vivax. CONCLUSION: This study suggests that PMNS often occurs after severe falciparum malaria. Concurrent P. vivax infection with pathogenic biomass being predominantly extravascular further complicates accurate diagnosis.

RESUMEN

People living with HIV (PLWH) experience a higher rate of age-related comorbidities at younger ages. Understanding common comorbidities among PLWH and their relationship to one another could be significant in improving aging for PLWH. The goal of the present study is to identify the most common comorbidities among PLWH and the relationship between them using network analysis. We used abstracted electronic medical record (EMR) data of PLWH from the Florida Cohort study, a prospective cohort study conducted in eight cities in Florida, USA. We used International Classification of Diseases (10th revision, ICD-10) code to classify comorbidities and organ systems. Network analysis was conducted to determine the degree and betweenness centrality among comorbidities. We included 756 PLWH with an average age of 46.4 years (SD 11.3) in the analysis. Infectious diseases (A00-B99, 50.8%), mental and behavioural (F01-F99, 47.0%), endocrine, nutritional and metabolic (E00-E88, 45.2%), and circulatory (I00-I99, 39%) disorders were the most prevalent system comorbidities among PLWH. Hypertensive disorder (I10-I1635.8%), dyslipidaemia (E78, 25.7%) and major depressive disorder (F32-F33, 23.9%) were the most common non-infectious conditions affecting PLWH. Viral hepatitis (B15-B19, 17.1%) and syphilis (A15-A53, 12%) were the most common coinfections among PLWH. Hypertension, dyslipidaemia and major depressive disorder were the most central of the comorbidities among PLWH. Comorbidities among PLWH were most prevalent for chronic disease and mental illness. Targeting shared disease risk factors in addition to monitoring known pathological pathways may prevent comorbidities among PLWH.

RESUMEN

CONTEXT: Digital video-based behavioral interventions are effective tools for improving HIV care and treatment outcomes. OBJECTIVE: To assess the costs of the Positive Health Check (PHC) intervention delivered in HIV primary care settings. DESIGN, SETTING, AND INTERVENTION: The PHC study was a randomized trial evaluating the effectiveness of a highly tailored, interactive video-counseling intervention delivered in 4 HIV care clinics in the United States in improving viral suppression and retention in care. Eligible patients were randomized to either the PHC intervention or the control arm. Control arm participants received standard of care (SOC), and intervention arm participants received SOC plus PHC. The intervention was delivered on computer tablets in the clinic waiting rooms. The PHC intervention improved viral suppression among male participants. A microcosting approach was used to assess the program costs, including labor hours, materials and supplies, equipment, and office overhead. PARTICIPANTS: Persons with HIV infection, receiving care in participating clinics. MAIN OUTCOME MEASURES: The primary outcome was the number of patients virally suppressed, defined as having fewer than 200 copies/mL by the end of their 12-month follow-up. RESULTS: A total of 397 (range across sites [range], 95-102) participants were enrolled in the PHC intervention arm, of whom 368 participants (range, 82-98) had viral load data at baseline and were included in the viral load analyses. Of those, 210 (range, 41-63) patients were virally suppressed at the end of their 12-month follow-up visit. The overall annual program cost was $402 274 (range, $65 581-$124 629). We estimated the average program cost per patient at $1013 (range, $649-$1259) and the cost per patient virally suppressed at $1916 (range, $1041-$3040). Recruitment and outreach costs accounted for 30% of PHC program costs. CONCLUSIONS: The costs of this interactive video-counseling intervention are comparable with other retention in care or reengagement interventions.

RESUMEN

The present study examines the HIV continuum of care outcomes among people living with HIV (PLWH) who have either recent (< 12-months) or distal (> 12-months) incarceration history compared to those without an incarceration history. A self-administered survey (as part of the Florida Cohort Study (n = 932)) was used to collect data on demographic information, linkage to care, retention in care, HIV medication adherence, viral suppression, and incarceration history. Those with recent incarceration history were least likely to report HIV medication adherence greater than or equal to 95% of the time (χ2 = 8.79; p = 0.0124), always take their medications as directed (χ2 = 15.29; p = 0.0005), and to have durable viral suppression (χ2 = 16.65; p = 0.0002) compared to those distally or never incarcerated. In multivariable analyses, those never and distally incarcerated had greater odds of care linkage ([vs recently incarcerated] AOR = 2.58; CI: 1.31, 5.07; p = 0.0063, AOR = 2.09; CI: 1.11, 3.95; p = 0.0228, respectively). Those never incarcerated had greater odds of taking ART as directed ([vs recently incarcerated] AOR = 2.53; CI: 1.23 - 5.19; p = 0.0116). PLWH with an incarceration history may need more on-going monitoring and follow-up HIV care than those without previous incarceration regardless of when incarceration occurred.


RESUMEN: El presente estudio examina el cuidado continuo entre las personas que viven con VIH (PVVS) con antecedentes penales recientes (en los últimos 12 meses) o más (> 12 meses) en comparación con aquellos sin antecedentes penales. Se utilizaron datos del Estudio de Cohorte de la Florida (n = 932). Se utilizó una encuesta auto administrada para recopilar datos sobre variables demográficas, vínculo al cuidado, retención al cuidado, adherencia a medicamentos contra el VIH, supresión viral e historial de encarcelamiento. Aquellos con antecedentes penales recientes fueron menos probable de reportar adherencia a medicamentos contra el VIH, mayor o igual a, el 95% de las ocasiones (χ2 = 8.79; p = 0.0124), tomando siempre sus medicamentos según las instrucciones (χ2 = 15.29; p = 0.0005), y tener una supresión viral duradera (χ2 = 16.65; p = 0.0002) en comparación con los encarcelados en el pasado o nunca encarcelados. En los análisis multivariables, aquellos que nunca fueron encarcelados y aquellos que estuvieron encarcelados hace mucho tiempo atrás tuvieron mayor probabilidad de estar vinculados con el cuidado médico ([en contraste con aquellos recientemente encarcelados]AOR = 2.58; CI: 1.31, 5.07; p = 0.0063, AOR = 2.09; CI: 1.11, 3.95; p = 0.0228, respectivamente). Aquellos que nunca fueron encarcelados tuvieron mayor probabilidad de tomar la TAR según indicado ([en contraste con aquellos recientemente encarcelados] AOR = 2.53; CI: 1.23 ­ 5.19; p = 0.0116). PVVS con historial de encarcelamiento necesitan más monitoreo y cuidado de seguimiento continuo en comparación con aquellos sin encarcelaciones previas, independientemente de cuando ocurrió el encarcelamiento.

RESUMEN

In 2013, Florida had the highest rate of new HIV infections and only 56% of persons living with HIV (PLWH) were virally suppressed. In response, we initiated a new HIV cohort in Florida to better understand issues affecting HIV health outcomes. This manuscript will describe the procedures of the Florida Cohort; summarize information regarding enrollment, follow-up, and findings to date; and discuss challenges and lessons learned during the establishment of a multisite cohort of PLWH. Florida Cohort participants were enrolled from eight clinics and community-based organizations geographically diverse counties across Florida. Data were obtained from participant questionnaires, medical records, and state surveillance data. From 2014-2018, 932 PLWH (44% ≥50 years, 64% male, 55% black, 20% Latinx) were enrolled. At baseline, 83% were retained in care and 75% were virally suppressed. Research findings to date have focused on outcomes such as the HIV care continuum, HIV-related comorbidities, alcohol and drug use, and mHealth interventions interest. Strengths included the diversity of the sample and the linkage of participant surveys with existing surveillance data. However, the study had several challenges during planning and follow-up. The lessons learned from this study can be helpful when initiating a new longitudinal cohort study.

RESUMEN

Persons with HIV (PWH) are aging. The impact of aging on healthcare utilization is unknown. The objective of this study was to evaluate hospitalization rates and reasons stratified by age among PWH in longitudinal HIV care. Hospitalization data from 2014-2015 was obtained on all adults receiving HIV care at 14 diverse sites within the HIV Research Network in the United States. Modified clinical classification software from the Agency for Healthcare Research and Quality assigned primary ICD-9 codes into diagnostic categories. Analysis performed with multivariate negative binomial regression. Among 20,608 subjects during 2014-2015, all cause hospitalization rate was 201/1000PY. Non-AIDS defining infection (non-ADI) was the leading cause for admission (44.2/1000PY), followed by cardiovascular disease (CVD) (21.2/1000PY). In multivariate analysis of all-cause admissions, the incidence rate ratio (aIRR) increased with older age (age 18-29 reference): age 30-39 aIRR 1.09 (0.90,1.32), age 40-49 1.38 (1.16,1.63), age 50-59 1.58 (1.33,1.87), and age ≥ 60 2.14 (1.77,2.59). Hospitalization rates increased significantly with age for CVD, endocrine, renal, pulmonary, and oncology. All cause hospitalization rates increased with older age, especially among non-communicable diseases (NCDs), while non-ADIs remained the leading cause for hospitalization. HIV providers should be comfortable screening for and treating NCDs.

RESUMEN

BACKGROUND: People living with HIV (PLHIV) are more likely to suffer from pain compared to the general public. Pain often clusters with mental health symptoms and substance use. This study sought to evaluate mental health and substance use factors associated with any pain and severe pain intensities among PLHIV. METHODS: Data were derived from HIV+ adults (N = 733) recruited from community health centers across Florida who completed questionnaires regarding demographics, chronic pain, HIV clinical outcomes, mental health symptoms, and substance use information. Pain was assessed using the Brief Pain Inventory (BPI) short form. Multivariate logistic regression analysis was utilized to assess the relationship between selected covariates and pain. RESULTS: Approximately half (45.0%) of participants reported having any current pain while 16.1% reported severe pain. The odds of having any current pain were 2.49 (CI 95% 1.48, 4.18, p <  0.01) times greater among PLHIV reporting anxiety and 1.69 (CI 95% 1.11, 2.57, p = 0.01) times greater among PLHIV reporting PTSD compared to those without those factors. The odds of having severe pain were 2.03 (CI 95% 1.03, 4.01, p = 0.04) times greater among PLHIV reporting anxiety and 2.02 (CI 95% 1.26, 3.24, p <  0.01) times greater among female participants compared to PLHIV without those factors respectively. Factors including depression, alcohol consumption, and marijuana use were not statistically associated with any current pain nor with severe pain. CONCLUSION: The relationship between pain and mental health is complex. Thus, future research is needed to determine if pain treatments may reduce mental health symptoms or if treatments can be targeted to address both issues simultaneously.

RESUMEN

An elderly woman presented with a 3-month history of nonhealing, tender ulcers involving the right calf and both forearms. She denied any history of similar lesions or trauma. Two trials of oral antibiotics had led to no improvement. Her medical history was significant for rheumatoid arthritis treated with methotrexate, hydroxychloroquine, and prednisone. A review of clinical manifestations was otherwise negative for disease. Physical examination of the patient's right calf revealed two punched-out ulcers with central necrotic black eschars, underlying retiform purpuric pattern, and mild fibrinopurulent drainage (Figure 1). Similar lesions were present on her forearms (Figures 2 and 3). No other remarkable skin changes were noted. The differential diagnosis included polyarteritis nodosa, cutaneous necrosis secondary to antiphospholipid syndrome, cryoglobulinemic vasculitis, and an atypical presentation of pyoderma gangernosum.

RESUMEN

BACKGROUND: Before implementation of the Patient Protection and Affordable Care Act (ACA) in 2014, 100 000 persons living with human immunodeficiency virus (HIV) (PLWH) lacked healthcare coverage and relied on a safety net of Ryan White HIV/AIDS Program support, local charities, or uncompensated care (RWHAP/Uncomp) to cover visits to HIV providers. We compared HIV provider coverage before (2011-2013) versus after (first half of 2014) ACA implementation among a total of 28 374 PLWH followed up in 4 sites in Medicaid expansion states (California, Oregon, and Maryland), 4 in a state (New York) that expanded Medicaid in 2001, and 2 in nonexpansion states (Texas and Florida). METHODS: Multivariate multinomial logistic models were used to assess changes in RWHAP/Uncomp, Medicaid, and private insurance coverage, using Medicare as a referent. RESULTS: In expansion state sites, RWHAP/Uncomp coverage decreased (unadjusted, 28% before and 13% after ACA; adjusted relative risk ratio [ARRR], 0.44; 95% confidence interval [CI], .40-.48). Medicaid coverage increased (23% and 38%; ARRR, 1.82; 95% CI, 1.70-1.94), and private coverage was unchanged (21% and 19%; 0.96; .89-1.03). In New York sites, both RWHAP/Uncomp (20% and 19%) and Medicaid (50% and 50%) coverage were unchanged, while private coverage decreased (13% and 12%; ARRR, 0.86; 95% CI, .80-.92). In nonexpansion state sites, RWHAP/Uncomp (57% and 52%) and Medicaid (18% and 18%) coverage were unchanged, while private coverage increased (4% and 7%; ARRR, 1.79; 95% CI, 1.62-1.99). CONCLUSIONS: In expansion state sites, half of PLWH relying on RWHAP/Uncomp coverage shifted to Medicaid, while in New York and nonexpansion state sites, reliance on RWHAP/Uncomp remained constant. In the first half of 2014, the ACA did not eliminate the need for RWHAP safety net provider visit coverage.

RESUMEN

BACKGROUND: Elite controllers spontaneously suppress human immunodeficiency virus (HIV) viremia but also demonstrate chronic inflammation that may increase risk of comorbid conditions. We compared hospitalization rates and causes among elite controllers to those of immunologically intact persons with medically controlled HIV. METHODS: For adults in care at 11 sites from 2005 to 2011, person-years with CD4 T-cell counts ≥350 cells/mm(2) were categorized as medical control, elite control, low viremia, or high viremia. All-cause and diagnostic category-specific hospitalization rates were compared between groups using negative binomial regression. RESULTS: We identified 149 elite controllers (0.4%) among 34 354 persons in care. Unadjusted hospitalization rates among the medical control, elite control, low-viremia, and high-viremia groups were 10.5, 23.3, 12.6, and 16.9 per 100 person-years, respectively. After adjustment for demographic and clinical factors, elite control was associated with higher rates of all-cause (adjusted incidence rate ratio, 1.77 [95% confidence interval, 1.21-2.60]), cardiovascular (3.19 [1.50-6.79]) and psychiatric (3.98 [1.54-10.28]) hospitalization than was medical control. Non-AIDS-defining infections were the most common reason for admission overall (24.1% of hospitalizations) but were rare among elite controllers (2.7%), in whom cardiovascular hospitalizations were most common (31.1%). CONCLUSIONS: Elite controllers are hospitalized more frequently than persons with medically controlled HIV and cardiovascular hospitalizations are an important contributor.

RESUMEN

In the 20th century, the concept of terrestrial life's unity was solidified, and the 21st century saw the emergence and establishment of astrovirology. To date, life originating beyond Earth has not been identified. The singular instance where NASA investigated potential microfossils in Martian ejecta found on Earth has since been refuted. This report suggests that a more comprehensive discussion and analysis of life's biosignatures and communication methods are essential. Such approaches are crucial not only to avoid overlooking the possible existence of extra-terrestrial intelligence (ETI) but also to prevent potential human infections that could arise from extra-terrestrial contact. In addition terrestrial infections by microorganism that originally derived from Earth and were returned, require investigation due to potential mutations and subsequent increased pathogenicity.

RESUMEN

Microbial organisms have been implicated in several mass extinction events throughout Earth's planetary history. Concurrently, it can be reasoned from recent viral pandemics that viruses likely exacerbated the decline of life during these periods of mass extinction. The fields of exovirology and exobiology have evolved significantly since the 20th century, with early investigations into the varied atmospheric compositions of exoplanets revealing complex interactions between metallic and non-metallic elements. This diversity in exoplanetary and stellar environments suggests that life could manifest in forms previously unanticipated by earlier, more simplistic models of the 20th century. Non-linear theories of complexity, catastrophe, and chaos (CCC) will be important in understanding the dynamics and evolution of viruses.

RESUMEN

BACKGROUND: Apathy is prevalent among people with HIV (PWH) and is associated with poor clinical outcomes. Cannabis use and Cannabis Use Disorder (CUD) are also disproportionately prevalent among PWH. CUD and younger onset of cannabis use may be linked to apathy in the general population; however, patterns of use most strongly associated with apathy have not been firmly established, and it is unclear whether cannabis use is linked to apathy in PWH. METHODS: We examined associations in 311 adult PWH between Apathy Evaluation Scale-Self (AES-S) scores and CUD history (current/past/no CUD/no cannabis use) and between AES-S scores and age of CUD onset (adolescent-onset/adult-onset). We also examined robustness of associations to adjustment for depressive symptoms (which may overlap with apathy symptoms) and alcohol use. RESULTS: Current CUD was associated with greater AES-S scores relative to cannabis users with no CUD history (ß = 2.13, 95 % CI = 0.37-3.90, p = 0.018). Adolescent-onset CUD was not associated with greater apathy relative to adult-onset CUD (ß = 0.56, 95 % CI = -2.57 - 3.68, p = 0.7). Associations became nonsignificant after adjustment for depressive symptoms, but not after adjustment for alcohol use. Alcohol use was correlated with apathy (r = 0.19, 95 % CI: 0.076-0.29, p = 0.001). CONCLUSIONS: Cannabis Use Disorder and at-risk alcohol use are associated with apathy among PWH; this finding highlights the need for substance use disorder prevention and treatment among PWH.

RESUMEN

World Health Organization (WHO) Risk Group-4 (RG-4) pathogens are among the most dangerous of the emergent and re-emergent viruses. International health agencies, working in concert, bridge the gaps in health care for populations at risk for RG-4 viral pathogen exposure. RG-4 virus research incorporates Biodefense Program and Biosafety Laboratory (BSL)-4 technologies. RG-4 viruses include Arena-viridae, Filo-viridae, Flavi-viridae, Herpes-viridae, Nairo-viridae, Paramyxo-viridae, and Pox-viridae.

RESUMEN

Filoviruses, categorized as World Health Organization (WHO) Risk Group 4 (RG-4) pathogens, represent significant global health risks due to their extraordinary virulence. The Filoviridae family encompasses Ebola strains such as Sudan, Zaire, Bundibugyo, Tai Forest (formerly known as Ivory Coast), Reston, and Bombali, in addition to the closely related Marburg and Ravn virus strains. Filoviruses originated from a common ancestor about 10,000 years ago and displayed remarkable consistency in genetic heterogeneity until the 20th century. However, they overcame a genetic bottleneck by mid-century. Paradoxically, this resulted in the emergence of boosted virulent strains from the 1970's onward. Filovirus research is included in the NIAID Biodefense Program and utilizes the highest level specialized protective laboratories, Biosafety Laboratory (BSL)-4. The spread of Filoviruses as well as other RG-4 pathogens within Africa poses a significant health threat increasingly both in Africa and out of Africa.

RESUMEN

Background: Patients with inborn errors of immunity (IEI) have increased risk of developing cancers secondary to impaired anti-tumor immunity. Treatment of patients with IEI and cancer is challenging as chemotherapy can exacerbate infectious susceptibility. However, the literature on optimal cancer treatment in the setting of IEI is sparse. Objectives: We present a patient with specific antibody deficiency with normal immunoglobins (SADNI), immune dysregulation (ID), and stage III ovarian carcinoma as an example of the need to modify conventional treatment in the context of malignancy, IEI, and ongoing infections. Methods: This is a retrospective chart review of the patient's clinical manifestations, laboratory evaluation and treatment course. Results: Our patient is a female with SADNI and ID diagnosed with stage III ovarian carcinoma at 60 years of age. Her ID accounted for antinuclear antibody positive (ANA+) mixed connective tissue diseases, polyarthralgia, autoimmune neutropenia, asthma, autoimmune thyroiditis, and Celiac disease. Due to the lack of precedent in the literature, her treatment was modified with continuous input from infectious disease, allergy/immunology and oncology specialist using a multidisciplinary approach.The patient completed debulking surgery and 6 cycles of chemotherapy. The dosing for immunoglobulin replacement therapy was increased for prophylaxis. Chemotherapy doses were lowered for all cycles preemptively for IEI. The therapy included carboplatin, paclitaxel, bevacizumab, and pegfilgrastim. The patient completed six-months of maintenance medication involving bevacizumab.Her treatment course was complicated by Mycobacterium avium-complex (MAC) infection, elevated bilirubin and liver enzymes attributed to excessive immunoglobulin replacement therapy, and urinary tract infection (UTI) and incontinence.Cancer genetic analysis revealed no targetable markers and primary immunodeficiency gene panel of 407 genes by Invitae was unrevealing. Lab tests revealed no evidence of Epstein-Barr Virus (EBV) infection. Post-chemotherapy imaging revealed no evidence of cancer for 1 year and 4 months, but the disease relapsed subsequently. The patient's lung scarring requires vigilance. Conclusions: Our patient with ovarian cancer and IEI required modified treatment and prevention of complications. In cases of IEI, optimal chemotherapy should be titrated to minimize immunosuppression yet treat cancer aggressively while decreasing the risk of infection with prophylactic antibiotics and prolonged post-treatment surveillance, including pulmonary evaluation.

RESUMEN

BACKGROUND: Marijuana use is common in persons with HIV, but there is limited evidence of its relationship with potential health benefits or harms. OBJECTIVE: The Marijuana Associated Planning and Long-term Effects (MAPLE) study was designed to evaluate the impact of marijuana use on HIV-related health outcomes, cognitive function, and systemic inflammation. METHODS: The MAPLE study is a longitudinal cohort study of participants living with HIV who were recruited from 3 locations in Florida and were either current marijuana users or never regular marijuana users. At enrollment, participants completed questionnaires that included detailed marijuana use assessments, underwent interviewer-administered neurocognitive assessments, and provided blood and urine samples. Ongoing follow-ups included brief telephone assessments (every 3 months), detailed questionnaires (annually), repeated blood and urine samples (2 years), and linkage to medical records and statewide HIV surveillance data. Supplemental measures related to intracellular RNA, COVID-19, Alzheimer disease, and the gut microbiome were added after study initiation. RESULTS: The MAPLE study completed enrollment of 333 persons between 2018 and 2021. The majority of participants in the sample were ≥50 years of age (200/333, 60.1%), male (181/333, 54.4%), cisgender men (173/329, 52.6%), non-Hispanic Black (221/333, 66.4%), and self-reported marijuana users (260/333, 78.1%). Participant follow-up was completed in 2022, with annual updates to HIV surveillance data through at least 2027. CONCLUSIONS: The MAPLE study is the largest cohort specifically designed to understand the use of marijuana and its effects on HIV-related outcomes. The study population has significant diversity across age, sex, gender, and race. The data will help clinicians and public health officials to better understand patterns of marijuana use associated with both positive and negative health outcomes, and may inform recommendations for future clinical trials related to medical marijuana and HIV.
