Abstract

Industrial activities and motor vehicle exhaust gases significantly contribute to air pollution; the longer the exposure to pollutants, the higher the pollutant levels in the blood. Online motorcycle taxi drivers in industrial areas have a high risk of being exposed to pollutants. This study aims to determine the risk factors that affect erythrocyte levels in online motorcycle taxi drivers in the industrial area of ​​Semarang City. The method used is analytic observational with a cross-sectional approach. Of 55 respondents, 41 had normal erythrocyte levels, and 14 had above-normal erythrocyte levels (polycythemia). Chi-square test results on smoking status, educational status, working length, and knowledge did not show a significant relationship (p <0.05) on erythrocyte levels in online motorcycle taxi drivers in industrial areas, Semarang City. The conclusion of this study, there is no significant relationship between smoking status, educational status, length of time working, and knowledge of the erythrocyte levels of online motorcycle taxi drivers in the Tanjung Emas industrial area, Semarang City.

Abstract

Treatment monitoring is crucial for preventing drug resistance, using both clinical and laboratory approaches. One parameter receiving increasing attention is the monocyte-to-lymphocyte ratio (MLR), which reflects the body's immune response to infection. Several studies have shown an increase in MLR in active TB patients, but its role as a predictive indicator of pulmonary TB treatment outcomes has not been fully studied. This study aimed to evaluate the value of MLR in predicting treatment success in pulmonary tuberculosis (TB) patients. This was a descriptive study with a cross-sectional design, using a population of smear-positive pulmonary tuberculosis patients undergoing treatment. A total of 40 newly diagnosed TB cases were randomly selected. Three ml of patient blood was collected in EDTA vacuum tubes and hematological parameters were analyzed. Blood was then drawn from the same patients after 1 month of antituberculosis treatment, and hematological parameters were analyzed. Pre- and post-treatment parameters were compared and analyzed using appropriate statistics. The results showed that patients diagnosed with pulmonary TB did not experience significant changes in monocyte-to-lymphocyte ratio (MLR) values ​​before and after treatment.
