Abstract
People with HIV (PWH) have an elevated risk for cardiovascular disease (CVD) compared with the general population. This study examined the feasibility, acceptability and preliminary efficacy of a tailored intervention aimed at increasing CVD risk perception and the adoption of heart-healthy behaviors in PWH. Forty adults were randomized to receive personalized feedback on CVD risk and discussion of risk reduction or health education. Participants were issued pedometers and seen for two treatment sessions. Participants were 60% male and had a mean age of 51.5 years. Ninety percent of participants completed all study sessions indicating good feasibility and acceptability. A medium effect size for the difference between treatment and control groups was found on both the Perceived Risk for Heart Disease (d = .38) and the Rapid Eating and Activity for Patients scales (d = .56) at 12 weeks. Atherosclerotic cardiovascular disease (ASCVD) risk score moderated the effect of treatment, such that at high (but not low) ASCVD risk, active intervention, compared to control, was associated with a greater increase in steps between baseline and both 8 (d = .38) and 12 weeks (d = .55). Findings provide preliminary evidence that tailored interventions delivered by nurses may be effective for primary prevention of CVD in PWH.

Abstract
Neutrophils are important components of the innate immune system that mediate pathogen defense by multiple processes including phagocytosis, release of proteolytic enzymes, production of reactive oxygen species, and neutrophil extracellular trap formation. Abnormalities of neutrophil count and function have been described in the setting of HIV infection, with the majority of antiretroviral agents (ARVs), excluding zidovudine, having been reported to correct neutropenia. Questions still remain, however, about their impact on neutrophil function, particularly the possibility of persistent neutrophil activation, which could predispose people living with HIV to chronic inflammatory disorders, even in the presence of virally-suppressive treatment. In this context, the effects of protease inhibitors and integrase strand transfer inhibitors, in particular, on neutrophil function remain poorly understood and deserve further study. Besides mediating hemostatic functions, platelets are increasingly recognized as critical role players in the immune response against infection. In the setting of HIV, these cells have been found to harbor the virus, even in the presence of antiretroviral therapy (ART) potentially promoting viral dissemination. While HIV-infected individuals often present with thrombocytopenia, they have also been reported to have increased platelet activation, as measured by an upregulation of expression of CD62P (P-selectin), CD40 ligand, glycoprotein IV, and RANTES. Despite ART-mediated viral suppression, HIV-infected individuals reportedly have sustained platelet activation and dysfunction. This, in turn, contributes to persistent immune activation and an inflammatory vascular environment, seemingly involving neutrophil-platelet-endothelium interactions that increase the risk for development of comorbidities such as cardiovascular disease (CVD) that has become the leading cause of morbidity and mortality in HIV-infected individuals on treatment, clearly underscoring the importance of unraveling the possible etiologic roles of ARVs. In this context, abacavir and ritonavir-boosted lopinavir and darunavir have all been linked to an increased risk of CVD. This narrative review is therefore focused primarily on the role of neutrophils and platelets in HIV transmission and disease, as well as on the effect of HIV and the most common ARVs on the numbers and functions of these cells, including neutrophil-platelet-endothelial interactions.

Abstract
Mental well-being can contribute to cigarette smoking and negatively impact disease progression among people living with HIV (PLWH). This study examined potential associations between cocaine use (COC), depression, and HIV status in predicting cigarette smoking; hypothesizing that depression would be highest in cocaine users and predict cigarette smoking. An exploratory analysis including stress was also examined as a potential predictor of cigarette use. More than half of the sample (65%) endorsed smoking at some point in the past, and 52% endorsed being current smokers at the time of the study. Smokers were most likely to be cocaine users (87.1%), cocaine using PLWH (74.3%), or PLWH (36.6%). Neither HIV status (χ2(1) = 1.5, p = .221), perceived stress (χ2(1) = 0.75 p = .386), nor depressive symptomatology (χ2(1) = 1.2, p = .274) were related to smoking. Non-cocaine users were approximately 95.4% less likely to smoke than cocaine users, controlling for all other variables. Overall, cocaine use was the greatest predictor of cigarette smoking and quantity of cigarettes smoked. Perceived stress and depression were not associated with cigarette smoking in the sample. Future interventions targeting cigarette use should include a cocaine-related component to encourage smoking cessation among this high-risk group.

Abstract
BACKGROUND People living with HIV (PLWH) experience a higher cardiovascular disease (CVD) risk. Yet, traditional algorithms are often used to estimate CVD risk. We evaluated the performance of 4 commonly used algorithms. SETTING The Netherlands. METHODS We used data from 16,070 PLWH aged ≥18 years, who were in care between 2000 and 2016, had no pre-existing CVD, had initiated first combination antiretroviral therapy >1 year ago, and had available data on CD4 count, smoking status, cholesterol, and blood pressure. Predictive performance of 4 algorithms [Data Collection on Adverse Effects of Anti-HIV Drugs Study (D:A:D); Systematic COronary Risk Evaluation adjusted for national data (SCORE-NL); Framingham CVD Risk Score (FRS); and American College of Cardiology and American Heart Association Pooled Cohort Equations (PCE)] was evaluated using a Kaplan-Meier approach. Model discrimination was assessed using Harrell's C-statistic. Calibration was assessed using observed-versus-expected ratios, calibration plots, and Greenwood-Nam-D'Agostino goodness-of-fit tests. RESULTS All algorithms showed acceptable discrimination (Harrell's C-statistic 0.73-0.79). On a population level, D:A:D, SCORE-NL, and PCE slightly underestimated, whereas FRS slightly overestimated CVD risk (observed-versus-expected ratios 1.35, 1.38, 1.14, and 0.92, respectively). D:A:D, FRS, and PCE best fitted our data but still yielded a statistically significant lack of fit (Greenwood-Nam-D'Agostino χ ranged from 24.57 to 34.22, P < 0.05). Underestimation of CVD risk was particularly observed in low-predicted CVD risk groups. CONCLUSIONS All algorithms perform reasonably well in PLWH, with SCORE-NL performing poorest. Prediction algorithms are useful for clinical practice, but clinicians should be aware of their limitations (ie, lack of fit and slight underestimation of CVD risk in low-risk groups).

Abstract
Evidence from epidemiological studies on the general population suggests that midlife cardiovascular disease (CVD) and/or metabolic syndrome (MetS) are associated with an increased risk of cognitive impairment and dementia later in life. In the modern combined antiretroviral therapy (cART) era, as in the general population, CVD and MetS were strongly and independently associated with poorer cognitive performances of sustained immunovirologically controlled persons living with human immunodeficiency viruses (PLHIVs). Those findings suggest that CV/metabolic comorbidities could be implicated in the pathogenesis of HIV-associated neurocognitive disorders (HAND) and might be more important than factors related to HIV infection or its treatment, markers of immunocompetence, or virus replication. The association between CVD/MetS and cognition decline is driven by still not well-understood mechanisms, but risk might well be the consequence of increased brain inflammation and vascular changes, notably cerebral small-vessel disease. In this review, we highlight the correspondences observed between the findings concerning CVD and MetS in the general population and virus-suppressed cART-treated PLHIVs to evaluate the real brain-aging processes. Indeed, incomplete HIV control mainly reflects HIV-induced brain damage described during the first decades of the pandemic. Given the growing support that CVD and MetS are associated with HAND, it is crucial to improve early detection and assure appropriate management of these conditions.

Abstract
Cardiovascular disease, venous thrombosis, and microvascular disease in people with HIV (PWH) is predicted to increase in an aging HIV-infected population. Endothelial damage and dysfunction is a risk factor for cardiovascular events in PWH and is characterized by impaired vascular relaxation and decreased nitric oxide availability. Vascular disease has been attributed to direct viral effects, opportunistic infections, chronic inflammation, effects of antiretroviral therapy, and underlying comorbid conditions, like hypertension and use of tobacco. Although biomarkers have been examined to predict and prognosticate thrombotic and cardiovascular disease in this population, more comprehensive validation of risk factors is necessary to ensure patients are managed appropriately. This review examines the pathogenesis of vascular disease in PWH and summarizes the biomarkers used to predict vascular disease in this population.

Abstract
BACKGROUND Cardiovascular disease (CVD) is an emerging cause of morbidity and mortality among HIV-positive patients receiving successful combination antiretroviral therapy, but their CVD risk has been rarely investigated in Asia-Pacific region. We aimed to assess the CVD risk of HIV-positive Taiwanese outpatients. METHODS We did cross-sectional questionnaire interviews to collect information of HIV-positive Taiwanese patients aged 40-79 at the HIV clinics of a medical center from 1 March to 31 August, 2017. The Framingham Risk Score (FRS), Atherosclerotic Cardiovascular Disease (ASCVD) risk score and Data-Collection on Adverse effects of Anti-HIV Drugs (D:A:D) risk score were used to estimate their CVD risk. RESULTS Of the screened 1251 patients, 1006 (80.4%) with complete data to assess their CVD risk were included for analyses. The prevalence of patients aged 40-75 and with a high CVD risk was 30.6% by FRS, 3.7% by D:A:D (R) risk score, and 22.2% by ASCVD risk score. In multiple logistic regression, older age, current smoking, higher systolic blood pressure, and higher triglyceride and fasting glucose levels were independently associated with the ASCVD risk score ≥7.5%. If current smokers aged 55-59 had stopped smoking, the proportions of them with a 10-year CVD risk of ≥10% by FRS and ≥7.5% by ASCVD risk score would have decreased by 35.3% and 20.0%, respectively. CONCLUSIONS Higher CVD risk estimates among HIV-positive Taiwanese aged 40-75 were associated with an older age, current smoking, higher systolic blood pressure, hypertriglyceridemia, and hyperglycemia. Smoking cessation could potentially lead to significant decreases of CVD risk.

Abstract
With the advent of antiretroviral therapy (ART), HIV-infected individuals are now living longer and healthier lives. However, ART does not completely restore health and treated individuals are experiencing increased rates of noncommunicable diseases such as dyslipidemia, insulin resistance, type 2 diabetes, cardiovascular disease, and nonalcoholic fatty liver disease. While it is well known that persistent immune activation and inflammation contribute to the development of these comorbid diseases, the mechanisms underlying this chronic activation remain incompletely understood. In this review, we will discuss emerging evidence that suggests that alterations in cellular metabolism may play a central role in driving this immune dysfunction in HIV patients on ART.

Abstract
HIV infection is a risk factor for cardiovascular disease (CVD). This risk is accentuated by certain combination antiretroviral therapies (cARTs), independent of their effects on lipid metabolism and insulin sensitivity. We sought to define potential mechanisms for this association through systematic review of clinical and preclinical studies of CVD in the setting of HIV/cART from the English language literature from 1989 to March 2018. We used PubMed, Web of Knowledge and Google Scholar, and conference abstracts for the years 2015-March 2018. We uncovered three themes: (1) a critical role for the HIV protease inhibitor (PI) ritonavir and certain other PI-based regimens. (2) The importance of platelet activation. Virtually all PIs, and one nucleoside reverse transcriptase inhibitor, abacavir, activate platelets, but a role for this phenomenon in clinical CVD risk may require additional postactivation processes, including: release of platelet transforming growth factor-β1; induction of oxidative stress with production of reactive oxygen species from vascular cells; suppression of extracellular matrix autophagy; and/or sustained proinflammatory signalling, leading to cardiac fibrosis and dysfunction. Cardiac fibrosis may underlie an apparent shift in the character of HIV-linked CVD over the past decade from primarily left ventricular systolic to diastolic dysfunction, possibly driven by cART. (3) Recognition of the need for novel interventions. Switching from cART regimens based on PIs to contemporary antiretroviral agents such as the integrase strand transfer inhibitors, which have not been linked to clinical CVD, may not mitigate CVD risk assumed under prior cART. In conclusion, attention to the effects of specific antiretroviral drugs on platelet activation and related profibrotic signalling pathways should help: guide selection of appropriate anti-HIV therapy; assist in evaluation of CVD risk related to novel antiretrovirals; and direct appropriate interventions.
