Twenty-six research assignments (papers) were presented, 11 free topics between lectures and case presentations and 15 posters; some of the presentations are related to work results, others with experience during missions and other topics at the end. Also present was a representative of the Ministry of Education, Doctor in Education Sciences and Professor Jorge Tamayo Collado, who works in Cuba as a researcher at the Central Institute of Pedagogical Sciences of the MINED, and that he is working in Saint Lucia on the implementation of the Program "Yes I can" and the Ambassador of Cuba, Alejandro Simancas. It was a fruitful day of knowledge exchanges, where the work, experience and results of each and every member of the Cuban Medical Brigade in Saint Lucia were presented. During the conclusions, Dr. José Luis López González, Chief of the Medical Brigade, stated that the challenge for the next Conference is greater, as they will try to improve the quality even more and develop the works in the English language. He recalled the words of our Commander-in-Chief 59 years ago, on January 15, 1960, The future of our Homeland must necessarily be a future of men of science, and added that like each and every one of his thoughts, this activity today takes on transcendental importance, for the times in which we live: "…because we live in these times when the role of thought is exceptional, because only thought can guide people in the times of great transformations and in the moments when great enterprises like this are being undertaken; taking our people forward".
