Abstract
Background :Chronic obstructive pulmonary disease (COPD) is a third leading cause of death.
Methods : In this case control study, we prepared 5 cc bloods from the antecubital vein of 100 COPD patients and 40 healthy individuals as control group. Vascular endothelial growth factor (VEGF) expression protein level was measured by ELISA in both groups.
Results : We found that concentration of VEGF in blood serum of patients with COPD (189.9±16pg/ml) was significantly higher than the control group (16.4±3.48pg/ml) (p<0.001). While VEGF serum level in emphysematous patients wasn’t significantly different with control group (p=0.07). Furthermore VEGF serum level in COPD patients was proportionally increased with severity of disease (p<0.001). Besides all COPD patients, regardless of their smoking status, were experienced significantly higher levels of VEGF than healthy ones (p=0.001 z=4.3).
Conclusion : Our results suggest VEGF serum concentration as the sensitive index for severity and activity of COPD and its prognosis.

Abstract
Background: Households’ financial protection against health payments and expenditures and equity in utilization
of health care services are of the most important tasks of governments. This study aims to measuring equity
in household’s health care payments according to fairness in financial contribution (FFC) and Kakwani indices
in Tehran-Iran, 2013.
Methods: This cross-sectional study was conducted in 2014.The study sample size was estimated to be 2200
households. Households were selected using stratified-cluster sampling including typical families who reside in
the city of Tehran. The data were analyzed through Excel and Stata v.11 software. Recall period for the inpatient
care was 1 year and for outpatient 1 month.
Results: The indicator of FFC for households in health financing was estimated to be 0.68 and the trend of the
indicator was ascending by the rise in the ranking of households’ financial level. The Kakwani index was estimated
to be a negative number (-0.00125) which indicated the descending trend of health financing system. By
redistribution of incomes or the exempt of the poorest quintiles from health payments, Kakwani index was estimated
to be a positive number (0.090555) which indicated the ascending trend of health financing system.
Conclusion: According to this study, the equity indices in health care financing denote injustice and a descending
trend in the health care financing system. This finding clearly shows that deliberate policy making in health
financing by national health authorities and protecting low-income households against health expenditures are
required to improve the equity in health.

Abstract
Background: Chronic Stable Angina (CSA) does not respond to clinical interventions always. Therefore, enhanced external counter pulsation (EECP) has been approved by the Food and Administration Drug (FDA) as an effective technology. This study aimed to synthesize evidence on the economic evaluation of EECP in managing CSA through a systematic approach.
Methods: In this systematic review study, PubMed/Medline, Cochrane Library, Web of Sciences, Scopus, National Institute for Health Research Journals Library, and the University of York Centre for Review and Dissemination (CRD) were searched. The targeted population was people who suffered from CSA, and the main therapeutic intervention was EECP. The comparators were not limited to any particular ones. Outcomes were changes in the Canadian Cardiovascular Society grading of angina pectoris, quality of life, and any other investigated relevant outcomes in the retrieved studies. The quality of studies was assessed through Philips et al and Joanna Briggs Institute Critical Appraisal tools. We synthesized data through a narrative approach.
Results: We retrieved 7821 studies; among which 3 studies were included in the final phase. Two studies were systematic reviews and the Markov model economic evaluation. Another study was a partial economic evaluation.
Conclusion: All studies only considered direct costs. EECP is a cost-effective technology in managing CSA, however, the sensitivity analysis of the studies showed the cost-effectiveness ratio is varied considerably and further studies are needed to extrapolate its economic value.
