Objective: To evaluate deaths, hospitalizations, and persistence of symptoms in patients with COVID-19 after infection in an outpatient setting during the first COVID-19 wave in Brazil.

Methods: This prospective cohort was between April 2020 and February 2021. Hospitalized or non-hospitalized COVID-19 patients until five days after symptom onset were included.

Psychological stress and cardiovascular risk among women in Brazilian communities: a cross-sectional study.

Psychosocial evaluations are rarely conducted with community-dwelling individuals, especially those with higher risk of cardiovascular disease. This study aims to evaluate the perceptual stress and cardiovascular risk among women in a large cross-sectional study performed in Brazilian communities. Subjects aged over 18 years were included out of 500 public basic health units (BHU) in Brazil.

In-Hospital influenza vaccination to prevent cardiorespiratory events in the first 45 days after acute coronary syndrome: A prespecified analysis of the VIP-ACS trial.

Background: Influenza vaccination prevents major cardiovascular events in individuals presenting a recent acute coronary syndrome (ACS), however the early effect of an in-hospital double-dose vaccination strategy remains uncertain.

Methods: The VIP-ACS was a randomized, pragmatic, multicenter, open-label trial with a blinded-adjudication endpoint. Patients with ACS ≤ 7 days of hospitalization were randomized to an in-hospital double-dose quadrivalent inactivated influenza vaccine (double-dose) or a standard-dose influenza vaccine at 30 days post-randomization.

Cardiovascular Safety of Azithromycin in Patients Hospitalized With COVID-19: A Prespecified Pooled Analysis of the COALITION I and COALITION II Randomized Clinical Trials.

The cardiovascular safety from azithromycin in the treatment of several infectious diseases has been challenged. In this prespecified pooled analysis of 2 multicenter randomized clinical trials, we aimed to assess whether the use of azithromycin might lead to corrected QT (QTc) interval prolongation or clinically relevant ventricular arrhythmias. In the COALITION COVID Brazil I trial, 667 patients admitted with moderate COVID-19 were randomly allocated to hydroxychloroquine, hydroxychloroquine plus azithromycin, or standard of care.

Stent composition and immune response after long-term coronary angioplasty.

Background: There are limited data about the influence of stent composition on immune responses after percutaneous coronary intervention (PCI).

Objective: The aim was to compare the effects of PCI with conventional cobalt-chromium bare metal stent (BMS) and drug-eluting stent (DES) implantation on the modulation of humoral and cellular immune responses.

Methods: A randomised, single-centre, open pilot study involving patients with stable coronary artery disease eligible for PCI was performed.

Immunometabolic and Vascular Health Responses among High Endurance Trained Subjects.

In this study, we aimed to examine the impact of high endurance training on vascular health parameters and immune-endocrine responses against modified low-density lipoprotein (LDL) particles. This observational, cross-sectional study included high endurance-trained and healthy non-trained subjects. Vascular ultrasound was used to assess vascular health parameters based on carotid intima-media thickness and endothelial function (flow-mediated dilation).

Primary Prevention of Cardiovascular Disease at Community Clinics in the State of Sao Paulo, Brazil: Results from the Epidemiological Information Study of Communities.

Background: Primary prevention of cardiovascular disease (CVD) remains a major challenge, especially in communities of low- and middle-income countries with poor medical assistance influenced by distinct local, financial, infrastructural, and resource-related factors.

Objective: This a community-based study aimed to determine the proportion and prevalence of uncontrolled cardiovascular risk factors (CRF) in Brazilian communities.

Methods: The EPICO study was an observational, cross-sectional, and community clinic-based study.

Influenza vaccination strategy in acute coronary syndromes: the VIP-ACS trial.

Aims: To evaluate whether a strategy of double-dose influenza vaccination during hospitalization for an acute coronary syndrome (ACS) compared with standard-dose outpatient vaccination (as recommended by current guidelines) would further reduce the risk of major cardiopulmonary events.

Methods And Results: Vaccination against Influenza to Prevent cardiovascular events after Acute Coronary Syndromes (VIP-ACS) was a pragmatic, randomized, multicentre, active-comparator, open-label trial with blinded outcome adjudication comparing two strategies of influenza vaccination following an ACS: double-dose quadrivalent inactivated vaccine before hospital discharge vs. standard-dose quadrivalent inactivated vaccine administered in the outpatient setting 30 days after randomization.

Phytosterol consumption and markers of subclinical atherosclerosis: Cross-sectional results from ELSA-Brasil.

Background And Aims: Phytosterol (PS) consumption is associated with lower total and LDL-cholesterol (LDL-c) concentrations, but its impact on cardiovascular risk is unclear. This study assessed the effect of usual intake of PS on markers of subclinical atherosclerosis in the Longitudinal Study of Adult Health (ELSA-Brasil).

Methods And Results: This cross-sectional study included 2560 participants of ELSA-Brasil, aged 48 (43-54) years, with available food frequency questionnaires (FFQ), coronary artery calcium (CAC) scores, carotid intima media thickness (cIMT), and carotid-femoral pulse wave velocity (cf-PWV), at baseline.

HIV-Infected Naïve Patients Exhibit Endothelial Dysfunction Concomitant with Decreased Natural Antibodies Against Defined Apolipoprotein B Autoantigens.

Backgorund: Traditional and HIV-defined risk factors may be associated with an increase in cardiovascular events. Recent studies have suggested that the humoral immune response to modified LDL may be associated with the process of atherosclerosis.

Objectives: To evaluate the presence of anti-oxLDL and apolipoprotein B-derived peptides in the blood, and their association with the endothelial function in HIV-infection.

Beneficial effects of green banana biomass consumption in patients with pre-diabetes and type 2 diabetes: a randomised controlled trial.

Diabetes mellitus is a global epidemic, characterised as a heterogeneous group of metabolic disorders associated with high risk of CVD. Green banana biomass, which is composed of resistant starches (RS) and cannot be hydrolysed by amylases, delays gastric emptying and modulates insulin sensitivity, thus contributing to improve metabolic disorders. The aim of the present study was to investigate the effects of consumption of RS from green banana biomass on body composition, fasting plasma glucose, glycated Hb (HbA1c) and homeostasis model assessment of insulin resistance in subjects with pre-diabetes or type 2 diabetes on top of treatment.

Effects of High-Intensity Training of Professional Runners on Myocardial Hypertrophy and Subclinical Atherosclerosis.

To evaluate the effects of long-term exposure to high-intensity training among professional runners on cardiac hypertrophy and subclinical atherosclerosis. Prospective study included runners of both sexes (n = 52) and age and gender matched controls (n = 57), without classical cardiovascular risk factors. Ventricular hypertrophy was quantified by echocardiography by linear method and carotid intima-media thickness (cIMT) by 2-D images obtained by ultrasonography.

Non-linear Optical Responses of Low-Density Lipoprotein are Associated with Intima-Media Thickness of Carotid Artery in Athletes.

We investigated the association between the degree of oxidative modification of LDL particles by non-linear optical response of LDL (Z-scan technique) and the presence of subclinical atherosclerosis in different segments of the carotid artery. We recruited high-intensity athlete runners (n = 44) and controls (n = 51) to participate in the study. The carotid intima-media thickness (cIMT), interleukin 10 (IL-10), TNF-alpha, and the non-linear optical responses of LDL particle (Z-scan) were assessed.

Antihypertensive therapy increases natural immunity response in hypertensive patients.

Aims: The aim of this work was to evaluate the effects of treatment of hypertension on the autoantibodies to apolipoprotein B-derived peptides (anti-ApoB-D peptide Abs) response, inflammation markers and vascular function.

Main Methods: Eighty-eight patients with hypertension (stage 1 or 2) were recruited and advised to receive perindopril (4mg), hydrochlorothiazide (25mg), or indapamide (1.5mg) for 12weeks in a blinded fashion.

Obesity modulates the immune response to oxidized LDL in hypertensive patients.

Obesity and hypertension have been recognized as inflammatory diseases capable of activating the immune system, thus contributing to an increased cardiovascular risk. However, the link between adaptive immunity, obesity, and hypertension is poorly understood. We investigated the relationship of the body mass index (BMI) on the inflammatory, vascular, and immune responses in patients with hypertension naïve of anti-hypertensive treatment.
