This article reflects on the future of the Brazilian Unified Health System (SUS, acronym in Portuguese), based on the foresight exercises conducted by the Brasil Saúde Amanhã initiative of the Oswaldo Cruz Foundation. The text briefly reviews some paths followed by the SUS as referred to in the Federal Constitution of 1988. It highlights the movement towards the decentralization of care and the constraint of health financial resources that reduced policies of increasing public expenditures. It examines the public and private arrangements for financing and provision of services that have resulted in sectoral privatization, mainly from economic policies articulated with concession of fiscal benefits. It analyzes the changes in the public sector financing through successive constitutional amendments that resulted in the weakening of established social protection policies, particularly of the health sector. For the future, the text considers population aging and analyzes trends in the epidemiological profile, with consequent changes in the health care paradigm. The article concludes by pointing out the consequences of fiscal strangling in the organization of the healthcare system and the need to reverse legal provisions that hamper the fulfillment of the constitutional mandate for equity and universality.

Vascular stents and stem cells have been used in high-acuity cases for many decades, particularly in cardiology. Providing the physician with another avenue of treatment, they have had a reasonable amount of success. However, there has been very little research conducted on seeding vascular stents with stem cells when treating intracranial aneurysms.

Background And Aims: Current heart failure (HF) risk stratification strategies require comprehensive clinical evaluation. In this study, artificial intelligence (AI) applied to electrocardiogram (ECG) images was examined as a strategy to predict HF risk.
Methods: Across multinational cohorts in the Yale New Haven Health System (YNHHS), UK Biobank (UKB), and Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), individuals without baseline HF were followed for the first HF hospitalization.

Overgrazing is the primary human-induced cause of soil degradation in the Caatinga biome, intensely threatening lands vulnerable to desertification. Grazing exclusion, a simple and cost-effective practice, could restore soils' ecological functions. However, comprehensive insights into the effects of overgrazing and grazing exclusion on Caatinga soils' multifunctionality are lacking.

The genus Wittmackia has 44 species distributed in two centers of diversity: the Brazilian clade and the Caribbean clade. The Brazilian clade includes 29 species, with geographic distribution concentrated in the Northeast of Brazil. This study reports the morphology, ultrastructure, pollen viability and stigma receptivity by different microscopy techniques of 23 species of the genus Wittmackia endemic to Brazil and occurring in Atlantic Forest areas.
