Background: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia, and its presentation differs according to age and sex. Recent studies have revealed differences in AF among various demographic groups, including the Latin American population.
Objectives: To better understand potential disparities in AF prevalence and treatment strategies in the Brazilian population through data from a large multicentric prospective registry.
Methods: The Rede D'Or AF registry is a multicenter prospective observational study including patients aged ≥ 18 years with AF who were seen in the emergency department of 32 tertiary hospitals in Brazil. Patients were characterized according to sex and other baseline characteristics and were classified according to previous anticoagulant use. The lack of anticoagulant use in patients with previous indications was analyzed. Statistical significance was set at 5%.
Results: The study data were from a total of 1955 patients enrolled. Male sex was more prevalent, and men were younger than the women. Due to an increased prevalence of previous AF episode and a higher CHA2DS2-VASc score, more women had indications for anticoagulant therapy; however, a significant proportion was not receiving this treatment. From 29 in-hospital deaths, 15 patients had previous indication for anticoagulation, but only 3 were using anticoagulants.
Conclusion: This study revealed sex-related differences in the Brazilian population of patients with AF that are consistent with trends in high-income countries. The promotion of better implementation of anticoagulant and antithrombotic therapies to reduce the risk of death and thromboembolic events among women with AF in Brazil is crucial.

Rapid control of hemorrhage is vital in first-aid and surgery. As representative of emergency hemostatic materials, inorganic porous materials achieve rapid hemostasis through concentrating protein coagulation factors by water adsorption to accelerate the coagulation reaction process, however their efficacy is often limited by the insufficient contact of material with blood and the lack of blood clot strength. Herein, we report an ultrafast dispersing and in situ gelation sponge (SG/DB) based on anchoring interface effect for hemorrhage control using freeze drying method after mixing fish scale gel (SG) and tert-butyl alcohol (TBA) pre-crystallized diatom biosilica (DB).

Dietary polysaccharides, recognised as significant natural bioactive compounds, have demonstrated promising potential for the prevention and treatment of cardiovascular disease (CVD). This review provides an overview of the biological properties and classification of polysaccharides, with particular emphasis on their extraction and purification methods. The paper then explores the diverse mechanisms by which polysaccharides exert their effects in CVD, including their antioxidant activity, protection against ischemia-reperfusion injury, anti-apoptotic properties, protection against diabetic cardiomyopathy, anticoagulant and antithrombotic effects, prevention of ventricular remodeling, and protection against vascular injury.

This study discusses disseminated intravascular coagulation (DIC) associated with solid cancers and various vascular abnormalities, both of which generally exhibit chronic DIC patterns. Solid cancers are among the most significant underlying diseases that induce DIC. However, the severity, bleeding tendency, and progression of DIC vary considerably depending on the type and stage of the cancer, making generalization difficult.

A thrombus straddling a patent foramen ovale (TSPFO) is a rare condition that presents significant health risks, including stroke or myocardial infarction, and can be life-threatening if not promptly addressed. We report the case of a 42-year-old female with morbid obesity who presented with sudden shortness of breath due to a bilateral pulmonary embolism. Imaging revealed a thrombus extending from the right atrium to the left atrium through the patent foramen ovale (PFO).

Background: Cardiac surgery patients are at increased risk for venous thromboembolism (VTE). Prevention is the most critical strategy to reduce VTE-associated morbidity and death. However, there is a lack of data on the optimal approach to VTE prophylaxis in this population of high-risk patients.
