The cardiovascular disease continuum begins with risk factors such as diabetes mellitus (DM), progresses to vasculopathy and myocardial dysfunction, and finally ends with cardiovascular death. Diabetes is associated with a 2- to 4-fold increased risk for heart failure (HF). Moreover, HF patients wit...h DM have a worse prognosis than those without DM. Diabetes can cause myocardial ischemia via micro- and macrovasculopathy and can directly exert deleterious effects on the myocardium. Hyperglycemia, hyperinsulinemia, and insulin resistance can cause alterations in vascular homeostasis. Then, reduced nitric oxide and increased reactive oxygen species levels favor inflammation leading to atherothrombotic progression and myocardial dysfunction. The classification, diagnosis, and treatment of HF for a patient with and without DM remain the same. Until now, drugs targeting neurohumoral and metabolic pathways improved mortality and morbidity in HF with reduced ejection fraction (HFrEF). Therefore, all HFrEF patients should receive guideline-directed medical therapy. By contrast, drugs modulating neurohumoral activity did not improve survival in HF with preserved ejection fraction (HFpEF) patients. Trials investigating whether sodium-glucose cotransporter-2 inhibitors are effective in HFpEF are on-going. This review will summarize the epidemiology, pathophysiology, and treatment of HF in diabetes.

Este documento de orientação para elaboração de um plano nacional de operacionalização e vacinação (NDVP) apresenta um esquema que auxilia os países a: desenvolver e atualizar o respectivo NDVP para a introdução de vacinas contra a COVID-19; elaborar estratégias para a operacionalizaçã...o e o monitoramento da(s) vacina(s) contra a COVID-19 no país; garantir que o plano e o financiamento relacionado estejam bem alinhados a outros planos nacionais de suporte à recuperação e resposta à COVID-19, e que a implementação esteja totalmente integrada nos mecanismos nacionais de governança.Este documento de orientação baseia-se em documentos de orientação já existentes sobre a introdução de novas vacinas, elaborados anteriormente pela OMS mediante consulta com especialistas no assunto, e é embasado por materiais recentes sobre vacinas contra a COVID-19, endossados pelo SAGE OMS

This document describes the ethical values that are most important to the nursing profession in Ontario. It also provides scenarios of ethical situations in which there is a conflict of values. Nurses are encouraged to use these scenarios for reflection and discussion. No solutions are offered becau...se there is no one solution that is best in all situations. The behavioural directives are intended to help nurses work through ethical situations and provide information about the College of Nurses of Ontario’s (CNO’s) expectations for ethical conduct. These are taken into account when CNO Committees assess nurses’ practices. Nurses need to consider behavioural directives carefully when making decisions about ethical care as this process will strengthen their practice.
