ABSTRACT
This study aimed to compare evidence-based medicine (EBM) vs. conventional approaches to journal club sessions in teaching critical appraisal skills in reading papers by emergency medicine residents. This double cut off discontinuation regression quasi-experimental study was conducted among emergency medicine residents. EBM vs. the conventional approach were applied to teach critical appraisal skills for half of the residents as an experimental group and another half as a control group respectively. Both groups participated in one hour monthly journal club sessions for six months. Before and after the study, all participants were examined by two tests: the Fresno Test (FT) [to evaluate their knowledge about EBM] and the Critical Appraisal Skills Test (CAST) [to evaluate their competency with critical appraisal skills]. The allocation of the participants into the experimental or control groups was according to their CAST scores before the study. 50 emergency medicine residents participated. After the study, the scores of both groups in the FT and CAST significantly improved (p<0.01), and the promotion of scores of the FT and CAST in the experimental group were more than that of the conventional group (p<0.0001). The current study indicated that an evidence-based medicine approach in journal club sessions was comparatively more advantageous compared to the conventional approach in teaching critical appraisal skills for reading papers among the residents of emergency medicine.

The present study aimed to determine the relationship between the level of air pollutants and the rate of ischemic stroke (IS) admissions to hospitals. In this retrospective cross-sectional study, stroke admissions (January-March 2012 and 2013) to an emergency department and air pollution and meteorological data were gathered. The relationship between air pollutant levels and hospital admission rates were evaluated using the generalize additive model. In all 379 patients with IS were referred to the hospital (52.5% male; mean age 68.2+/-13.3 years). Both transient (p<0.001) and long-term (p<0.001) rises in CO level increases the risk of IS. Increased weekly (p<0.001) and monthly (p<0.001) average O3 levels amplifies this risk, while a transient increase in NO2 (p<0.001) and SO2 (p<0.001) levels has the same effect. Long-term changes in PM(10) (p<0.001) and PM(2.5) (p<0.001) also increase the risk of IS. The findings showed that the level of air pollutants directly correlates with the number of stroke admissions to the emergency department.

The aim of this study, we have compared the advantages of oral dydrogestrone with vaginal progesterone [cyelogest] for luteal support in intrauterine insemination [IUI] cycles. Progesterone supplementation is the first line treatment when luteal phase deficiency [LPD] can reasonably be assumed. This study was conduct to compare the effect of oral dydrogestrone with vaginal Cyelogest on luteal phase support in the IUI cycles. This prospective, randomized, double blind study was performed in a local infertility center from May 2013 to May 2014. It consisted of 150 infertile women younger than35years old undergoing ovarian stimulation for IUI cycles. They underwent ovarian stimulation with oral dydrogesterone [20 mg] as group A and vaginal cyelogest [400 mg] as group B in preparation for the IUI cycles. Clinical pregnancy and abortion rates, mid luteal progesterone [7 days after IUI] and patient satisfaction were compared between two groups, The mean serum progesterone levels was significantly higher in group A in comparison with group B [p=0.001]. Pregnancy rates in group A was not statistically different in comparison with group B [p =0.58]. Abortion rate in two groups was not statistically different [p =0.056] although rate of abortion was higher in group B in comparison with A group. Satisfaction rates were significantly higher in group A compared to group B [p<0.001]. We concluded that oral dydrogestrone is effective as vaginal progesterone for luteal-phase support in woman undergoing IUI cycles. Moreover, the mean serum progesterone levels and satisfaction rates in dydrogestrone group were higher than cyelogest group
