We have organized uninterruptedly annually since 2008 the symposium "Nephrology a Day in One Day", which until 2019 was held in person in the city of Medellín, and in 2020 for the first time and due to the pandemic we held it virtually, with the assistance of 1,900 physicians, including nephrologists, internists, endocrinologists, cardiologists, general practitioners, family physicians, physicians from kidney and cardiovascular risk programs, and auditors, from all over Colombia and 13 countries. All this effort is published on our website, including memoirs written in the first years of the event and later in audio and video.
