International longitudinal registry of patients with atrial fibrillation and treated with rivaroxaban: RIVaroxaban Evaluation in Real life setting (RIVER)

Background Real-world data on non-vitamin K oral anticoagulants (NOACs) are essential in determining whether evidence from randomised controlled clinical trials translate into meaningful clinical benefits for patients in everyday practice. RIVER (RIVaroxaban Evaluation in Real life setting) is an ongoing international, prospective registry of patients with newly diagnosed non-valvular atrial fibrillation (NVAF) and at least one investigator-determined risk factor for stroke who received rivaroxaban as an initial treatment for the prevention of thromboembolic stroke. The aim of this paper is to describe the design of the RIVER registry and baseline characteristics of patients with newly diagnosed NVAF who received rivaroxaban as an initial treatment. Methods and results Between January 2014 and June 2017, RIVER investigators recruited 5072 patients at 309 centres in 17 countries. The aim was to enroll consecutive patients at sites where rivaroxaban was already routinely prescribed for stroke prevention. Each patient is being followed up prospectively for a minimum of 2-years. The registry will capture data on the rate and nature of all thromboembolic events (stroke / systemic embolism), bleeding complications, all-cause mortality and other major cardiovascular events as they occur. Data quality is assured through a combination of remote electronic monitoring and onsite monitoring (including source data verification in 10% of cases). Patients were mostly enrolled by cardiologists (n = 3776, 74.6%), by internal medicine specialists 14.2% (n = 718) and by primary care/general practice physicians 8.2% (n = 417). The mean (SD) age of the population was 69.5 (11.0) years, 44.3% were women. Mean (SD) CHADS2 score was 1.9 (1.2) and CHA2DS2-VASc scores was 3.2 (1.6). Almost all patients (98.5%) were prescribed with once daily dose of rivaroxaban, most commonly 20 mg (76.5%) and 15 mg (20.0%) as their initial treatment; 17.9% of patients received concomitant antiplatelet therapy. Most patients enrolled in RIVER met the recommended threshold for AC therapy (86.6% for 2012 ESC Guidelines, and 79.8% of patients according to 2016 ESC Guidelines). Conclusions The RIVER prospective registry will expand our knowledge of how rivaroxaban is prescribed in everyday practice and whether evidence from clinical trials can be translated to the broader cross-section of patients in the real world

Manejo de pragas.

Independentemente de seu propósito ? grãos, sementes, forragem ou cobertura do solo ?, a cultura da aveia é hospedeira de um grande número de insetos fitófagos. Da mesma forma, após a colheita, grãos e sementes desse cereal estão sujeitos à infestação de várias pragas durante o armazenamento.bitstream/item/227766/1/Lau-Cap7-2021.pd

Uma história sobre inimigos naturais.

Resumo: Controlar uma praga por meios biológicos requer conhecer o seu papel em redes tróficas e utilizar/manipular os organismos que compõem esta rede de forma a reduzir a sua população. Este artigo apresenta destaques históricos do controle biológico de pulgões em trigo no Brasil

Monitorar e manejar.

O ano de 2019 foi bastante favorável à ocorrência de pulgões e transmissão de vírus como o nanismo-amarelo na cultura do trigo. A importância destas epidemias tem levado a iniciativas para facilitar o monitoramento e a tomada de decisão de manejo desses afídeos. Esforços incluem o uso da Tecnologia de Informaçã
