Abstract
Introduction: Fire fighting is one of the most dangerous jobs, in which workers with bulky clothing, require high energy and aerobic capacity to carry out intensive activities, such as firefighting and rescue. The purpose of this study was to determine the maximum aerobic capacity and its related factors using treadmill test in firefighters of Zahedan.
Methods: In this descriptive-analytic cross-sectional study, 40 firefighting personnel of Zahedan were randomly selected and evaluated. The job satisfaction questionnaire was used and aerobic capacity was determined in a treadmill test. Spearman correlation coefficients, Mann-Whitney, and Kruskal-Wallis were used to analyze of the data.
Results: The average maximum oxygen consumed in firefighters was 38.08 ± 14.02 mL/kg/min. There was no significant correlation between age and maximum aerobic capacity yet there was a reversed relationship between the amount of oxygen uptake and work experience (r = -0.386, P 0.014), maximum heart rate (r = -0.846, P < 0.001), body mass index (r = -0.623, P < 0.001), and job satisfaction (r = -0. 322, P = 0.043).
Conclusions: The maximum aerobic capacity of the firefighters was higher than the reported values in many other occupational groups, yet it was lower compared with International Association of Fire Fighters recomendation. Therefore, increasing the maximum aerobic power of firefighters with a regular exercise program and pre-employment examinations is recommended to ensure that the physical work capacity is proportionate to the job.

Abstract
Introduction: Resistant and extensive resistant tuberculosis is one of the most important infectious diseases and the most important challenge in the treatment of tuberculosis. The aim of this study was to evaluate the direct treatment costs of patients with resistant and extensive resistant tuberculosis and the risk factors for developing resistance to the treatment of this disease.
Methods: This descriptive-analytical study estimated the treatment costs of resistant and extensive resistant tuberculosis in elderly patients referred to Masih Daneshvari Hospital during 2009-2010 and then the risk factors for resistance in these patients were investigated. For this purpose, 268 refractory tuberculosis patients were randomly selected. Data were analyzed using SPSS software version 17 using descriptive statistics and Pearson and Spearman tests and t-test.
Results: The mean age and length of stay of patients were 59.96±15.45 years and 43.17± 5.8 days, respectively. 97.01% of patients had a history of tuberculosis. The average cost of medicine, diagnostic services and hospital services was estimated at 594.81, 1387.31 and 10972.28 rail millions, respectively. The relationship between direct costs of treatment and age, length of hospital stay and occupation was statistically significant (P≤0.05) but its relationship with education level and gender was not significant (P˃0.05).
Conclusions: Considering that hospitalization and prolongation of hospitalization costs a lot of money, so it is suggested that following the correct treatment protocols and principles of DOTs, these costs can be reduced and on the other hand follow up patients with a history of disease to prevent the spread and recurrence. Recurrence of the disease seems necessary.
