Objective: To determine the blood levels of two oxidative stress biomarkers among native women exposed to wood smoke living at high altitude (3,850 m a.s.l.). Malondialdehyde (MDA) levels and carboxyhemoglobin (COHb) percentage in venous blood, which is also a cellular hypoxia biomarker, were analyzed. Materials and methods: A descriptive case-series study conducted in 74 women between 14 and 55 years of age exposed to wood smoke and coming from the rural area of the Copacabana Municipality (La Paz, Bolivia) at 3,850 m a.s.l. Screening was carried out through a survey and a complete physical examination. MDA levels and COHb percentage in venous blood were determined, and the demographic variables and transcutaneous oxygen saturation were measured. A descriptive statistical analysis was performed and measures of central tendency were calculated using IBM SPSS Statistics Version 18. Result...

Objective: To characterize the cardiorespiratory function and the state of oxidative stress resulting from the exposure to wood smoke in women who live at high altitude (3,850 m a.s.l.). Materials and methods: An observational case-series study. The cardiorespiratory function was analyzed, and thebiomarkers of oxidative stress malondialdehyde (MDA) and carboxyhemoglobin (COHb) were quantified. Measures of central tendency and dispersion were determined. The statistical methods of association and correlation were implemented. Results: Sixty (60) patients were included in the research. Fifty percent (50.00 %) of the participants showed clinical evidence of heart disease and 25.00 % had clinical symptoms of respiratory disease. Forty-five percent (45.00 %) of the spirometries revealed normal values. Thirty-six point six seven percent (36.67 %) showed a decrease in the forced expiratoryvolum...
