RESUMO
ABSTRACT In Cuba, newborn screening (NBS) for cystic fibrosis (CF) was introduced in January 2019. The results from the first three years of the CF NBS program are presented. An IRT/IRT protocol was followed using a cut-off value of 50 ng/mL. In this period 281,717 neonates were screened, 2,197 samples had increased IRT values, and a second sample was necessary (recall rate=0.78%). In 686 (0.24%) neonates, IRT was still elevated, and they were referred for clinical evaluation. Twenty-one children were confirmed by sweat test and molecular biology. Eighteen newborns presented variant F508del. A false negative case was reported. Demographic data of 32,764 neonates were collected. The average age of sampling was six days with results available at 11 days of life, but 1.7% of the samples were collected 20 days after birth. The mean IRT value was 12.7±11.7 ng/mL (ranging 0-283 ng/mL) with a calculated 98.5 percentile value of 42.4 ng/mL. On average, the samples were processed five days after collection and two days after they were received at the laboratory. Although CF NBS program in Cuba is just beginning, it can be predicted that CF will be one of the most frequent inherited-metabolic diseases in the Cuban population.

Mientras, para valorar la validez teórica de la estrategia pedagógica, se utilizó el Criterio de Expertos (Método Delphy). La factibilidad desde el punto de vista práctico se constató a partir del pre-experimento. Los resultados obtenidos reflejaron que la estrategia contribuyó al perfeccionamiento de la formación ética del profesor de levantamiento de pesas en la provincia de Pinar del Río.

It was used the expert criteria (Delphy method), The practical feasibility was confirmed through a pre-experiment. The outcomes reflect that the strategy contributed to the improvement of the ethic formation in the weightlifting professor at the province Pinar del Río, showing its theoretical validity.
