Background and Aim Oppositional Defiant Disorder (ODD) with hyperactivity is one of the behavioral disorders in childhood and adolescence. The mobile health is an economical, available, and useful tool for training the mothers with ODD and hyperactive child. The research aimed to examine the effectiveness of parent training behavioral management program by mobile health to mothers to reduce oppositional and aggression symptoms in children with ODD and hyperactivity.
Methods and Materials The method of this research was a single case experiment by the A-B model. The participants of this study ranged from 7 to 12 years old children and their mothers in Tehran who referred to Rooyesh-e-Talaee Institute and diagnosed with ODD and hyperactivity in 2018. Four children and their mothers were selected with simple random sampling. The intervention implemented in ten 60- 90-minute sessions. For data analysis using the charts, improve percent, and RCI.
Ethical Considerations The Research Ethics Committee of Khatam University, Iran approved this study (Code: Kh.96.S.100.3123).
Results Children with ODD and hyperactivity showed improvement in comparison with baseline measures. The overall improvement in their defiant was 61.43% and in aggression was 55.33%, and the RCI was higher than 1.96 for all three children. The results showed that the two hypotheses were clinically significant.
Conclusion The mobile health training with its related apps was a useful, low cost, available, and suitable method for mothers with ODD and hyperactive children. It can also be complementary to counseling services for mothers with the ODD and hyperactive children. Besides, this technology can be helpful for the country's health system and sustainable health development.

Background and Aim: The deaths caused by traffic accidents are one of the three leading causes of death in Iran. Considering that all deaths from traffic accidents in the forensic organization are undergoing autopsy and also in the treatment centers under oral autopsies, the cause of death is determined, we determined that the cause of reported death from oral autopsy and medical autopsy Compare the law.
Methods & Materials: In this descriptive study, patients who were admitted to the forensic medical center during the year 1395 admitted to the Vali-e-Asr Hospital in Arak, were referred. The causes of death in Vali-asr Hospital were evaluated and compared with the outcome of the forensic oral hearing. 
Ethical Considerations: This study ethcally approved by the ethics committee of the Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1395.226).
Results: In this study, 109 patients (1.33%) died from a total of 8153 patients with traffic accidents referred to Valiasr hospital in Arak. Of these, 68.8% were male and 31.2% were women. The Mean±SD age of the patients died was 44.03±22.43 years. Also, 59.6% of the dead died during the first 24 hours of the accident. The most common cause of death, according to the results of oral autopsy, was “multiple injuries,” accounting for 49.5% of the patients in 45 patients.
Conclusion: Abundance of deaths among patients with road traffic accidents and they referred to Valiasr hospital, which was 1.33%. According to the existing standards and considering that the mortality rate in this center is less than 1.5%. It seems that the level of service delivery in this center is favorable.

Introduction: Patients with COVID-19 can have various and complex coagulation disorders that cause hypercoagulable conditions. Investigating the role of anticoagulants with different doses in the outcome of patients with COVID-19 seems to be needed. Therefore, the present study was conducted with the aim of predicting factors of severe disease, including the number of lymphocytes, LDH, and the recovery status of patients. 
Methods: A cross-sectional study was conducted in patients with COVID-19 hospitalized in Hazrat Rasool Akram (PBUH) Hospital. Study entry includes acute respiratory symptoms caused by COVID-19 disease (uncontrollable cough, dyspnea, prolonged medicine and blood saturation drop) along with lung involvement in chest spiral CT scan without injection, SARS RT-PCR–CO virus test was positive and transfer to intensive care unit (ICU) was indicated. Anticoagulant starting time, type and dose of anticoagulant received and duration of use were recorded. Two groups of prophylaxis dose, higher dose than prophylaxis (medium dose and therapeutic dose) were divided.
Results: Out of the total number of patients referred to Rasul Akram Hospital, 90 people (43 women (47.8%) and 47 men (52.22%)) participated in this study. The average hospitalization in the ICU was 13.50 ± 12.39 days and 17.18 ± 13.36 days in the hospital. Also, the duration of coagulant therapy was 17.13 ± 13.38 days. 53 patients (58.9%) received a prophylactic dose, 28 patients (31.1%) received a therapeutic dose, and 9 patients (10%) received a moderate dose of anticoagulant. Anticoagulant in 74 patients (82.2%) was unfractionated heparin (UFH) and in 16 cases (17.8%) low molecular weight heparin (LMWH). The changes of LDH, number of lymphocytes, dimer, fibrinogen, ferritin and FDP according to the dose of anticoagulant assessed in the three groups of prophylaxis, treatment and no statistically significant difference. The mean of ICU admission days according to different doses of anticoagulant did not show a statistically significant difference.
Conclusions: Finally, the findings obtained from the study showed that the use of different doses of anticoagulant does not cause a difference in the level of LDH, number of lymphocytes, ferritin and FDP at different measurement times. Also, the length of stay in the hospital and the time of hospitalization in the intensive care unit did not differ between the groups receiving prophylactic anticoagulant, medium dose and therapeutic dose.
