Methods: a bibliometric study of the articles published in the journal Universidad Médica Pinareña during the period 2017-2020 was carried out. The universe studied consisted of 177 articles. The following variables were analyzed: year of publication, type of article, number of authors, country of origin of the main author, language in which the article was written, number of bibliographic references and their degree of updating. Descriptive statistics were used and the Price and annual collaboration indexes were calculated. Results: it was found that 88 (49,7 %) papers were original and 61 (34,5 %) belonged to the year 2020. A total of 614 authors published, with an average of 3,5 authors per article. It was observed that 58 (32,8 %) articles were signed by five authors, 168 (94,9 %) came from Cuba, and 175 (98,9 %) were written in Spanish. The annual collaboration index had an average value of 3,44. The average number of bibliographic references per article was 13,6 and the Price index was 0,67. Conclusions: the journal had satisfactory metric indicators. There was an increase in originality and adequate updating of its contents; however, there is a tendency to a decrease in the percentage of updating of bibliographic references.

A posteroanterior chest X-ray is indicated, showing a rounded radiopaque image of 3-4 cm in diameter in the left hilar and parahilar region, with well-defined edges. A biopsy of the lung lesion and lymph node was performed, confirming an epithelial bronchogenic tumor, squamous cell carcinoma type with lymph node metastasis. The patient maintains clinical stability and receives treatment with chemotherapy and multidisciplinary care.
