Persons living with human immunodeficiency virus (PLHIV) are at increased risk of atherosclerotic cardiovascular disease (ASCVD). In spite of this, uptake of evidence-based clinical interventions for ASCVD risk reduction in the HIV clinic setting is sub-optimal. EXTRA-CVD is a 12-month randomized clinical effectiveness trial that will assess the efficacy of a multi-component nurse-led intervention in reducing ASCVD risk among PLHIV. Three hundred high ASCVD risk PLHIV across three sites will be randomized 1:1 to usual care with generic prevention education or the study intervention. The study intervention will consist of four evidence-based components: (1) nurse-led care coordination, (2) nurse-managed medication protocols and adherence support (3) home BP monitoring, and (4) electronic health records support tools. The primary outcome will be change in systolic blood pressure and secondary outcome will be change in non-HDL cholesterol over the course of the intervention. Tertiary outcomes will include change in the proportion of participants in the following extended cascade categories: (1) appropriately diagnosed with hypertension and hyperlipidemia (2) appropriately managed; (3) at treatment goal (systolic blood pressure <130 mm Hg and non-HDL cholesterol < National Lipid Association targets). The EXTRA-CVD trial will provide evidence appraising the potential impact of nurse-led interventions in reducing ASCVD risk among PLHIV, an essential extension of the HIV care continuum beyond HIV viral suppression.

Objective To investigate whether an internet based, nurse led vascular risk factor management programme promoting self management on top of usual care is more effective than usual care alone in reducing vascular risk factors in patients with clinically manifest vascular disease.Design Prospective randomised controlled trial.Setting Multicentre trial in secondary and tertiary healthcare setting.Participants 330 patients with a recent clinical manifestation of atherosclerosis in the coronary, cerebral, or peripheral arteries and with at least two treatable risk factors not at goal.Intervention Personalised website with an overview and actual status of patients’ risk factors and mail communication via the website with a nurse practitioner for 12 months; the intervention combined self management support, monitoring of disease control, and drug treatment.Main outcome measures The primary endpoint was the relative change in Framingham heart risk score after 1 year. Secondary endpoints were absolute changes in the levels of risk factors and the differences between groups in the change in proportion of patients reaching treatment goals for each risk factor.Results Participants’ mean age was 59.9 (SD 8.4) years, and most patients (n=246; 75%) were male. After 1 year, the relative change in Framingham heart risk score of the intervention group compared with the usual care group was −14% (95% confidence interval −25% to −2%). At baseline, the Framingham heart risk score was higher in the intervention group than in the usual care group (16.1 (SD 10.6) v 14.0 (10.5)), so the outcome was adjusted for the separate variables of the Framingham heart risk score and for the baseline Framingham heart risk score. This produced a relative change of −12% (−22% to −3%) in Framingham heart risk score for the intervention group compared with the usual care group adjusted for the separate variables of the score and −8% (−18% to 2%) adjusted for the baseline score. Of the individual risk factors, a difference between groups was observed in low density lipoprotein cholesterol (−0.3, −0.5 to −0.1, mmol/L) and smoking (−7.7%, −14.9% to −0.4%). Some other risk factors tended to improve (body mass index, triglycerides, systolic blood pressure, renal function) or tended to worsen (glucose concentration, albuminuria).Conclusion An internet based, nurse led treatment programme on top of usual care for vascular risk factors had a small effect on lowering vascular risk and on lowering of some vascular risk factors in patients with vascular disease.Trial registration Clinical trials NCT00785031.

Objective To assess the cost-effectiveness of an internet-based, nurse-led vascular risk factor management programme in addition to usual care compared with usual care alone in patients with a clinical manifestation of a vascular disease. Design Cost-effectiveness analysis alongside a randomised controlled trial (the Internet-based vascular Risk factor Intervention and Self-management (IRIS) study). Setting Multicentre trial in a secondary and tertiary healthcare setting. Participants 330 patients with a recent clinical manifestation of atherosclerosis in the coronary, cerebral, or peripheral arteries and with ≥2 treatable vascular risk factors not at goal. Intervention The intervention consisted of a personalised website with an overview and actual status of patients’ vascular risk factors, and mail communication with a nurse practitioner via the website for 12 months. The intervention combined self-management support, monitoring of disease control and pharmacotherapy. Main outcome measures Societal costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness. Results Patients experienced equal health benefits, that is, 0.86 vs 0.85 QALY (intervention vs usual care) at 1 year. Adjusting for baseline differences, the incremental QALY difference was −0.014 (95% CI −0.034 to 0.007). The intervention was associated with lower total costs (€4859 vs €5078, difference €219, 95% CI −€2301 to €1825). The probability that the intervention is cost-effective at a threshold value of €20 000/QALY, is 65%. At mean annual cost of €220 per patient, the intervention is relatively cheap. Conclusions An internet-based, nurse-led intervention in addition to usual care to improve vascular risk factors in patients with a clinical manifestation of a vascular disease does not result in a QALY gain at 1 year, but has a small effect on vascular risk factors and is associated with lower costs. Trial registration number NCT00785031.

We have recently identified conventional B2 cells as atherogenic and B1a cells as atheroprotective in hypercholesterolemic ApoE(-/-) mice. Here, we examined the development of atherosclerosis in BAFF-R deficient ApoE(-/-) mice because B2 cells but not B1a cells are selectively depleted in BAFF-R deficient mice. We fed BAFF-R(-/-) ApoE(-/-) (BaffR.ApoE DKO) and BAFF-R(+/+)ApoE(-/-) (ApoE KO) mice a high fat diet (HFD) for 8-weeks. B2 cells were significantly reduced by 82%, 81%, 94%, 72% in blood, peritoneal fluid, spleen and peripheral lymph nodes respectively; while B1a cells and non-B lymphocytes were unaffected. Aortic atherosclerotic lesions assessed by oil red-O stained-lipid accumulation and CD68+ macrophage accumulation were decreased by 44% and 50% respectively. B cells were absent in atherosclerotic lesions of BaffR.ApoE DKO mice as were IgG1 and IgG2a immunoglobulins produced by B2 cells, despite low but measurable numbers of B2 cells and IgG1 and IgG2a immunoglobulin concentrations in plasma. Plasma IgM and IgM deposits in atherosclerotic lesions were also reduced. BAFF-R deficiency in ApoE(-/-) mice was also associated with a reduced expression of VCAM-1 and fewer macrophages, dendritic cells, CD4+ and CD8+ T cell infiltrates and PCNA+ cells in lesions. The expression of proinflammatory cytokines, TNF-α, IL1-β and proinflammatory chemokine MCP-1 was also reduced. Body weight and plasma cholesterols were unaffected in BaffR.ApoE DKO mice. Our data indicate that B2 cells are important contributors to the development of atherosclerosis and that targeting the BAFF-R to specifically reduce atherogenic B2 cell numbers while preserving atheroprotective B1a cell numbers may be a potential therapeutic strategy to reduce atherosclerosis by potently reducing arterial inflammation.

Option to attenuate atherosclerosis by depleting B2 cells is currently limited to anti-CD20 antibodies which deplete all B-cell subtypes. In the present study we evaluated the capacity of a monoclonal antibody to B cell activating factor-receptor (BAFFR) to selectively deplete atherogenic B2 cells to prevent both development and progression of atherosclerosis in the ApoE(-/-) mouse. To determine whether the BAFFR antibody prevents atherosclerosis development, we treated ApoE(-/-) mice with the antibody while feeding them a high fat diet (HFD) for 8 weeks. Mature CD93(-) CD19(+) B2 cells were reduced by treatment, spleen B-cell zones disrupted and spleen CD20 mRNA expression decreased while B1a cells and non-B cells were spared. Atherosclerosis was ameliorated in the hyperlipidemic mice and CD19(+) B cells, CD4(+) and CD8(+) T cells were reduced in atherosclerotic lesions. Expressions of proinflammatory cytokines, IL1β, TNFα, and IFNγ in the lesions were also reduced, while MCP1, MIF and VCAM-1 expressions were unaffected. Plasma immunoglobulins were reduced, but MDA-oxLDL specific antibodies were unaffected. To determine whether anti-BAFFR antibody ameliorates progression of atherosclerosis, we first fed ApoE(-/-) mice a HFD for 6 weeks, and then instigated anti-BAFFR antibody treatment for a further 6 week-HFD. CD93(-) CD19(+) B2 cells were selectively decreased and atherosclerotic lesions were reduced by this treatment. Anti-BAFFR monoclonal antibody selectively depletes mature B2 cells while sparing B1a cells, disrupts spleen B-cell zones and ameliorates atherosclerosis development and progression in hyperlipidemic ApoE(-/-) mice. Our findings have potential for clinical translation to manage atherosclerosis-based cardiovascular diseases.

Da Silva et al. showed that the triglyceride-glucose (TyG) index was positively associated with a higher prevalence of symptomatic coronary artery disease (CAD). TyG has been used in healthy individuals as a marker of insulin resistance. The use of this index as a marker of atherosclerosis in cardiovascular disease (CVD) patients might be influenced by diabetes and the hyperlipidemic state that led to CVD. Certain considerations might be necessary before we conclude that the TyG index can be used as a marker of atherosclerosis in CVD patients. These factors can highlight the role of fasting blood glucose and triglyceride levels that are used in the TyG formula. Comparing the fasting blood glucose and/or triglyceride levels with the TyG index in these patients to show how much value the TyG index can add to clinical practice seems to be necessary. Conclusions of such studies might be biased by these facts. Stratification by CAD disease category cannot help achieve an understanding of the role of TyG in CVD. Correlations do not imply causation, so the use of the TyG index as an index in CAD patients is questionable.

Background Atherosclerotic cardiovascular disease (ASCVD)—including ischemic heart disease (IHD), ischemic stroke (IS), and peripheral arterial disease (PAD)—is a leading cause of death and disability worldwide, creating a significant socioeconomic burden. In Brazil, ASCVD accounts for most cardiovascular-related hospitalizations and deaths; comprehensive national estimates of societal costs for IHD, IS, and PAD are still limited. This study aims to estimate the direct and indirect societal costs of IHD, IS, and PAD in Brazil from both public and private healthcare perspectives, and to project their economic burden for the 2025–2029 period. Methods Data were extracted from official national databases, including DATASUS (public sector), TISS (private sector), SIM (mortality), and InfoLogo (social security). Direct medical costs were derived from hospitalizations recorded between 2008 and 2023. Indirect costs included productivity losses due to absenteeism and premature mortality among individuals aged 14–64 years. Future costs were projected using the Exponential Smoothing with Error, Trend, and Seasonality (ETS) model. Results ASCVD is projected to cause over 600,000 hospitalizations annually in Brazil, generating direct medical costs exceeding BRL 5.9 billion in 2029. Indirect costs related to premature mortality and absenteeism will reach approximately BRL 4.5 billion annually. The total projected 5-year societal burden (2025–2029) amounts to BRL 59.4 billion, with IHD representing the largest share of both direct and indirect costs. Conclusions ASCVD imposes a substantial and growing economic burden on Brazilian society, driven primarily by direct healthcare expenditures and productivity losses from premature deaths. These findings highlight the need for strengthened prevention, early detection, and risk-factor management strategies to mitigate the clinical and economic impact of atherosclerotic disease in Brazil.

The present comment on Qiu’s work intends to emphasize two points: (1) Cardiovascular prevention must start early due to the progressive nature of atherosclerosis. (2) growing evidence that coaching performed by nurses leads to effective results. Nurses can intercept the young population who must be sensitized and educated about prevention.

Clinicopathological studies are important in determining the brain lesions underlying dementia. Although almost 60% of individuals with dementia live in developing countries, few clinicopathological studies focus on these individuals. We investigated the frequency of neurodegenerative and vascular-related neuropathological lesions in 1,092 Brazilian admixed older adults, their correlation with cognitive and neuropsychiatric symptoms, and the accuracy of dementia subtype diagnosis. In this cross-sectional study, we describe clinical and neuropathological variables related to cognitive impairment in 1,092 participants (mean age = 74 y, 49% male, 69% white, and mean education = 4 y). Cognitive function was investigated using the Clinical Dementia Rating (CDR) and the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE); neuropsychiatric symptoms were evaluated using the Neuropsychiatric Inventory (NPI). Associations between neuropathological lesions and cognitive impairment were investigated using ordinal logistic regression. We developed a neuropathological comorbidity (NPC) score and compared it to CDR, IQCODE, and NPI scores. We also described and compared the frequency of neuropathological diagnosis to clinical diagnosis of dementia subtype. Forty-four percent of the sample met criteria for neuropathological diagnosis. Among these participants, 50% had neuropathological diagnoses of Alzheimer disease (AD), and 35% of vascular dementia (VaD). Neurofibrillary tangles (NFTs), hippocampal sclerosis, lacunar infarcts, hyaline atherosclerosis, siderocalcinosis, and Lewy body disease were independently associated with cognitive impairment. Higher NPC scores were associated with worse scores in the CDR sum of boxes (β = 1.33, 95% CI 1.20-1.46), IQCODE (β = 0.14, 95% CI 0.13-0.16), and NPI (β = 1.74, 95% CI = 1.33-2.16). Compared to neuropathological diagnoses, clinical diagnosis had high sensitivity to AD and high specificity to dementia with Lewy body/Parkinson dementia. The major limitation of our study is the lack of clinical follow-up of participants during life. NFT deposition, vascular lesions, and high NPC scorewere associated with cognitive impairment in a unique Brazilian sample with low education. Our results confirm the high prevalence of neuropathological diagnosis in older adults and the mismatch between clinical and neuropathological diagnoses.

Background Intermittent claudication (IC) is a classic symptom of peripheral arterial disease, and strongly associated with coronary heart disease and cerebrovascular disease. Treatment of IC and secondary prevention of vascular events include best medical treatment (BMT), changes in lifestyle, most importantly smoking cessation and increased physical exercise, and in appropriate cases surgery. A person-centred and health promotion approach might facilitate breaking barriers to lifestyle changes and increasing adherence to secondary prevention therapy. The FASTIC study aims to evaluate a nurse-led, person-centred, health-promoting follow-up programme compared with standard follow-up by a vascular surgeon after surgical treatment for IC. Methods The FASTIC-study is a multicentre randomised controlled clinical trial. Patients will be recruited from two hospitals in Stockholm, Sweden after surgical treatment of IC through open and/or endovascular revascularisation and will be randomly assigned into two groups. The intervention group is offered a nurse-led, person-centred, health-promoting programme, which includes two telephone calls and three visits to a vascular nurse the first year after surgical treatment. The control group is offered standard care, which consists of a visit to a vascular surgeon 4–8 weeks after surgery and a visit to the outpatient clinic 1 year after surgical treatment. The primary outcome is adherence to BMT 1 year after surgical treatment and will be measured using The Swedish Prescribed Drug Registry. Clinical assessments, biomarkers, and questionnaires will be used to evaluate several secondary outcomes, such as predicted 10-year risk of cardiovascular and cerebrovascular events, health-related quality of life, and patients’ perceptions of care quality. Discussion The FASTIC study will provide important information about interventions aimed at improving adherence to medication, which is an unexplored field among patients with IC. The study will also contribute to knowledge on how to implement person-centred care in a clinical context. Trial registration ClinicalTrials.gov NCT03283358 , registration date 06/13/2016.
