With due attention to increasing use of X-ray imaging techniques, raising the level of knowledge of employees in this regard can play an important role in reducing the frequency of genetic abnormalities and carcinogenesis caused by radiation in the community. The purpose of this study was to evaluate the level of awareness of nurses in intensive care units from radiation protection during portable radiography. In a descriptive cross-sectional study, 92 nurses working in intensive care units were evaluated. Data were collected by a two-part questionnaire including 4 questions about demographic information (age, sex, background and education) and 11 questions regarding radiation protection. Data were analyzed by SPSS software version 21 using t-test, ANOVA and Kruskal-Wallis tests. The significance level was less than 0.05 of participants, 38.9% had poor knowledge (score less than 5), 56.9% had moderate knowledge (score of 5 to 7) and 4.2% had good knowledge (score of 8 and more). The difference of mean score in male and female and between nurses with different educational levels was not significant (P=0.470 and 0.683, respectively). The mean score in personnel with different work history and age did not show significant difference (P=0.098 and 0.222, respectively). The level of knowledge from radiation protection was moderate and weak in our study. It seems that the provision of in-person training as well as educational brochures in shorter intervals have a good effect on personnel knowledge from radiation protection.

Traumatic brain injury (TBI) is a brain injury caused by physical external forces on the head that leads to changes in the brain tissue. Epidemiologic studies help to identify the key opportunities for decreasing burden of TBI, cost-effective prevention and treatment of TBI. This study was conducted to investigate the epidemiology and radiologic findings of patients with traumatic brain injures who referred to emergency department in Iran. In this retrospective descriptive-analytic study, the data of patients (n=267) with TBI admitted to Emergency Department of Shahid Mohammadi hospital of Hormozgan University of Medical Sciences were considered during 2017 year. The administrative dataset of Shahid Mohammadi hospital was used in the current study. Mean of age for patients was 29.87 years and 228 patients (85.00%) were men and 39 patients (15.00%) were women. The most trauma was associated to road accidents (n=203, 67%), 58 cases (21.70%) for falling from heights, 4 cases (1.54%) for struggle and 2 cases (0.7%) for water injury. The data showed that 35 patients (13.10%) were dead due to trauma and 232 patients (86.90%) survived. The results showed that epidural hematoma (EDH) (n=79) and subarachnoid hemorrhage (SAH) (n=71) had most incidence. The results showed a significant relation between age and trauma mechanism (P<0.05), so that 58 patients <18 years of age injured from road accidents, while 133 patients 18-60 years of age injured form road accidents. In conclusion, the most common causes of TBI in Bandar Abbas are accidents that must be reduced by traffic rules and transport safety.

Topological index is a type of molecular descriptor calculated based on the molecular graph of a chemical compound. Topological indices are used for developing the quantitative structure activity relationships (QSARs) in which the biological activity or other properties of the molecules are correlated with their chemical structure. Eccentric connectivity indices are the well-known topological indices in this regards. In this research study, we computed some eccentric connectivity indices of the V-Phenylenic nanotube VPHX[p;q], these are our results.
