Introduction: Biomarkers are biological or biochemical substances which emerge as a response of the organism on certain types of tumors and which reflect the stage or degree of them. Objective: To determine the association of tumoral markers with the chronic respiratory events. Methods: A descriptive and cross-sectional study of 306 patients diagnosed with chonic respiratory diseases and assisted at the Pneumology community outpàtients from Santiago de Cuba province was carried out from January, 2014 to December, 2018. Results: Male sex and ages between 60 o 69 years as well as interstitial diseases, chronic bronchitis and the chronic obstructive pulmonary disease predominated in the series. Likewise, radiological studies were also important for detecting neoplasic processes, mainly with the use of the axial computerized tomography. On the other side, markers presenting altered values were the CYFRA 21.1 y el CA 72.4, so that its association with the chronic respiratory processes. Conclusions: Tumoral biomarkers are an usefull tool in the follow-up of patients with malignant neoplasies, but also they show altered values in the presence of different chronic respiratory diseases, which doesn´t mean there is a malignant process.

A descriptive and cross-sectional study of 199 patients diagnosed with lung cancer, assisted in the Pneumology Service of "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital was carried out in Santiago de Cuba, from January, 2014 to December, 2017, aimed at determining the association of tumoral markers with the neoplastic process. In the series there was a prevalence of the male sex and patients aged 50 to 69, as well as the IIIB and IV stages of the disease. In a same way it was more frequent the localization in the right lung and the histologic type non small cells lung cancer, from which adenocarcinoma was more representative. On the other hand, CYFRA 21.1 and CA 72.4 were the two markers associated with lung tumoral processes and were confirmed as such. [ABSTRACT FROM AUTHOR]

Introduction: Metabolic syndrome represents a constellation of lipid risk factors and non lipid leading to the onset of cardiovascular disease, stroke, diabetes mellitus with implications on morbidity and mortality of these patients. Objective: To evaluate the behavior of metabolic syndrome in a group of randomly selected patients. Method: A descriptive study aimed at understanding the behavior of the metabolic syndrome in 129 patients attending the outpatient area of the Central Clinical Laboratory, General Hospital Dr. "Juan Bruno Zayas Alfonso" the city of Santiago de Cuba in the province of the same name in the period from January to June 2010. Results: A high percentage of the population studied was associated with the presence of cardiovascular risk factors with low HDL-C values in both male and female, 82.9% and 89.5% respectively, higher triglyceride, 81.6 % in females and 74.3% in males and over 50% of patients of both sexes expressed high levels of blood pressure both systolic and diastolic. There was a higher prevalence of metabolic syndrome in men with 63.6% of all male patients, in relation to women who also showed a high percentage (51.4%) in their prevalence. Conclusions: The association of risk factors that predominated in patients with metabolic syndrome was hypertriglyceridemia, hypertension and low HDL cholesterol. These results indicate that interventions should be undertaken and programs to encourage healthier lifestyle changes and preventive treatments that prevent the development of complications.
