Buford L. Nichols receives an honorary doctoral degree in science from Universidad Francisco Marroquín. He addressed a speech and thanked UFM for the recognition and friendship given to him along many years. He speaks about his early contributions to the implementation of feeding protocols now widely used in Guatemalan national hospitals. Nichols explains his interest in the impact of diarrhea in infants with malnutrition, and how this became his principal motivation of his medical experience in Guatemala. He relates the collaboration done with Hospital Roosevelt and describes the work done by a special unit of investigation that centered its resources on these matters. Nichols talks about the promising doctors he worked with during the project, which still have an important role in the medical world; and finally, he illustrates Plan de Xelajú and testifies on how this program benefited not only Guatemalan hospitals but international ones as well.
