Background: The post-acute cardiovascular manifestations of COVID-19, known as long COVID, have yet to be comprehensively characterized. There is also an increased risk of heart failure in individuals without cardiovascular disease before SARS-CoV-2 infection. The literature lacks information regarding the characteristics of patients with long COVID who developed advanced heart failure refractory to guideline-directed medical therapy.
Methods: We describe the characteristics of patients with long COVID (LC) who were listed for heart transplantation. The study population comprised 45 patients listed for heart transplantation, divided into 2 groups: patients with etiologies other than LC (n = 41) and patients with LC (n = 4) between January 2020 and March 2022. The endpoint of this study was the description of the characteristics of each group.
Results: The average duration of hospitalization after the acute infectious episode with SARS-CoV-2 was 150 ± 113 days, and all patients were hospitalized in New York Heart Association class IV. All LC patients were oligosymptomatic in the initial infection, did not require hospitalization in the acute phase, had a lower ejection fraction, used more intra-aortic balloon pumps, had lower pulmonary vascular resistance, and fewer comorbidities compared with other etiologies, suggesting a clinical feature compatible with low cardiac output rather than congestion.
Conclusions: This study is an early investigation of patients listed for heart transplantation due to a complex syndrome of COVID-19. These preliminary findings warrant further large-scale investigation.

The persistence or emergence of long-term symptoms following resolution of primary SARS-CoV-2 infection is referred to as long COVID or post-acute sequelae of COVID-19 (PASC). PASC predominantly affects the cardiovascular, neurological, respiratory, gastrointestinal, reproductive, and immune systems. Among these, the central nervous system (CNS) is significantly impacted, leading to a spectrum of symptoms, including fatigue, headaches, brain fog, cognitive impairment, anosmia, hypogeusia, neuropsychiatric symptoms, and peripheral neuropathy (neuro-PASC).

Introduction: During the COVID-19 pandemic, major events with immune-modulating effects at population-level included COVID-19 infection, lockdowns, and mass vaccinations campaigns. As immune responses influence many immune-mediated diseases, population scale immunological changes may have broad consequences.
Methods: We investigated the impact of lockdowns, COVID-19 infection and vaccinations on immune responses in the 2000HIV study including 1895 asymptomatic virally-suppressed people living with HIV recruited between October 2019 and October 2021.

Background: There are few studies in the literature evaluating post-COVID mortality in Brazil, along medium and long term, especially in those who presented severe clinical disease.
Objective: This study aims to investigate the factors associated with post-COVID mortality of severe acute respiratory syndrome (SARS) cases from 2020 to 2023 in Brazil, along medium and long term.
Methods: Retrospective cohort study using notification data of SARS classified as COVID-19 from the Brazilian National Information System, "Sistema de Vigilância Epidemiológica (SIVEP)," during the period 2020 to 2023.
