Background and Objectives: Lower back pain is a common orthopedic illness that has a reasonable relationship to pronated foot. The aim of this study was to determine the effects of resistance training with Thera-Band on the electromyography frequency domain of trunk and lower limb muscles of patients with both low back pain and pronated feet during walking. Materials and Methods: This clinical trial study was carried out at the University of Mohaghegh Ardebil in 2018. At first 30 men with low back pain and pronated feet were selected by convenience sampling and then randomly divided into control (n=15) and experimental (n=15) groups. An electromyographic system was used to record the activity of trunk and lower limb muscles during walking. Two-way ANOVA was used for statistical analysis. Results: During the post-test phase compared with the pre-test phase in the experimental group, the median frequency of the tibialis anterior muscle (p=0.013) was lower during the loading response phase and the median frequency of the abdominal external oblique muscle (p=0.015) was larger during the loading response phase. In addition, during the post-test phase compared with the pre-test phase in the experimental group, the median frequency of the abdominal external oblique muscle (p=0.029) was higher during the push off phase. Also, during the loading response phase, the main effect of the group on the median frequency of biceps femoris (p=0.015) and erector spine (p=0.009) was statistically significant. Conclusion: Considering the high activity of the tibialis anterior muscle in the patients with low back pain with pronated feet compared to the healthy subjects, there was a significant reduction in the median frequency of the tibialis anterior muscle during post-test compared with the pre-test during the loading response phase that shows the positive effects of this exercise protocol.

Background and Objective: Indiscriminate use of antibiotics is one of the major health problems worldwide. Rapidly increasing incidence of antibiotic-resistant microbes warns healthcare authorities in the country to use drugs, reasonably. This study was carried out to assess the pattern of antibiotic usage in Razi teaching hospital in Ahvaz, southwest of Iran. Methods: This descriptive -analytical study was conducted on 17668 hospitalized patients in Razi teaching hospital Ahvaz, southwest of Iran during 2012. Proper or inappropriate antibiotic usage was judged based on existing national guidelines or guidelines referenced in textbooks. Results: 3119 of patients were received antibiotics which 20.4% of patients were being treated unnecessarily. 2482 (79.6%) of patients had indications for antibiotic therapy. Out of 2482 patients with indications for antibiotic therapy, 51.9%, 18.1 % and 6.5 % of patients were received incorrect antibiotic regiment, inadequate dose and unsuitable duration of therapy, respectively. The highest rate of unnecessary, inappropriate, incorrect duration and dosage of antibiotics were observed in internal, scorpion wards and the lowest was in infectious diseases and obstetrics wards (P<0.05). Conclusion: The pattern of antibiotic usage in Razi teaching hospital in Ahvaz was inappropriate. Unnecessary prescription, inappropriate antibiotic spectrum, inadequate dose and duration of antibiotics were inappropriate treatment strategy. [ABSTRACT FROM AUTHOR]

In previous researches, exploration of the theme of Ayyari and teachings of Javanmardi and branches of this socio-political rite has focused mostly on prose and sometimes poetic mystical texts due to elitist view of researchers, and centrality and special status of the Holy Quran and religious texts. Perhaps, elucidating and representing the close relation of Ayyari and Javanmardi to epic texts and showing didactic teachings of this moral society can be a new and impressive effort to reveal its primary and Iranian origin and also correct some existing incorrect considerations. By this background in mind, the present paper aims to introduce in two sections the theoretical foundations of research in four axes including: prose epic narratives, didactic literature, its nature and branches, historical background and ups and downs of Ayyari and Javanmardi. Then, by comparative and typological approach in two prose epics Samak-e Ayyar and Darabnameh, didactic-suggestive teachings of Ayyaran and Javanmardan are analyzed and described. Having an almost comprehensive view on previous studies in this field, the present article reveals some points not considered before.

ABSTRACTBACKGROUND AND OBJECTIVE: Cardiac arrhythmia is a potentially fatal complication of acute coronary syndromes. Researchers believe that the magnesium disturbance is an important factor causing the arrhythmias. This study aimed to investigate the relationship between serum magnesium levels and the incidence of cardiac arrhythmias in patients with acute coronary syndromes.METHODS: This observational study was performed as a cohort, 124 goal-oriented patients were evaluated (two groups of hypomagnesemia and normomagnesemia, 62 subjects in each group. Variables included patient demographics, primary diagnosis of acute coronary syndrome, magnesium levels, cardiac arrhythmia and its rate and origin. At first, serum magnesium levels were measured and then the patients were followed up for incidence of cardiac arrhythmias for 72 hours, and two groups were compared with each other. FINDINGS: In this study, 17 subjects (24.7%) in hypomagnesemia and 8 patients (12.9%) in normomagnesemia group had cardiac arrhythmia showing a statistically significant difference (p=0.044). However the magnesium level was not related to subgroup of arrhythmia and its rate, also magnesium level was not related to the type of acute coronary syndromes.CONCLUSION: According to the obtained results, it may be concluded that there is a significant association between serum magnesium level and cardiac arrhythmia among this patients.
