Association Between Venous Mesenteric Thrombosis and Plasminogen Activator Inhibitor-1 Mutation.

Plasminogen activator inhibitor-1 (PAI-1) is central to fibrinolysis regulation, and genetic variants such as the 4G/4G genotype predispose individuals to hypercoagulability. This case highlights a 46-year-old female patient presenting with acute mesenteric venous thrombosis, where genetic evaluation revealed homozygosity for the PAI-1 4G/4G polymorphism. Management with unfractionated heparin followed by a transition to direct oral anticoagulants led to clinical resolution.

Arbovirus exposure and subclinical myocardial dysfunction in an Indigenous population in Northeast Brazil: a cross-sectional study.

Background: Human activities, such as urbanization and climate change, have facilitated the spread of arbovirus-carrying vectors, disproportionately affecting vulnerable traditional Indigenous communities.

Objective: To explore the relationships between subclinical myocardial dysfunction, assessed by global longitudinal strain (GLS), and comprehensive arbovirus serology in an Indigenous population, while also describing the serological and epidemiological profile of dengue, chikungunya, and Zika viruses.

Methods: This ancillary study is part of the first phase (2016-2017) of the Project of Atherosclerosis among Indigenous Populations (PAI), a cross-sectional study involving participants from two Indigenous communities with different degrees of urbanization and a highly urbanized city in Northeast Brazil.

Morbidity and factors associated with frailty in post-COVID-19 elderly patients attended at a reference center.

Objective: To assess the morbidity profile and identify factors associated with frailty syndrome in post-COVID-19 elderly patients treated at the only Reference Center for Elderly Health Care in northern Minas Gerais.

Methods: This is a case series study, utilizing the Clinical-Functional Vulnerability Index-20 (CFVI-20) and Comprehensive Geriatric Assessment (CGA) to characterize and evaluate the health condition of the group. To define the variables associated with frailty, a multivariate analysis was conducted.

Outcomes of mechanical thrombectomy for medium vessel occlusion in acute ischemic stroke patients with ASPECTS 4-5 vs. 6-7: a retrospective, multicenter, and multinational study.

Introduction: Mechanical thrombectomy (MT) efficacy in medium vessel occlusion (MeVO) stroke, particularly in patients with low Alberta Stroke Program Early Computed Tomography Score (ASPECTS), remains less explored.

Methods: This retrospective study analyzed data from 443 AIS patients treated with MT for MeVO and low ASPECTS (4-7) at 37 centers across North America, Asia, and Europe, from September 2017 to July 2021. Patients were categorized into ASPECTS of 4-5 and 6-7.
