Traumatic brain injury is a major cause of death and disability in adults. This study investigated the effect of oral administration of amantadine on the neurological outcomes of patients with diffuse axonal injury (DAI) in the intensive care unit (ICU). This double-blind clinical trial was conducted in the ICU of Imam Hospital in Urmia. Patients with DAI were intubated and received mechanical ventilation in the ICU. They were divided into 2 groups: patients receiving amantadine (A) and placebo (P). The acquired data were analyzed using SPSS, P < .05 significant level. Findings showed no significant difference between the 2 groups in age and sex. There was no significant difference between the mean Glasgow Coma Scale (GCS) at the time of admission and discharge, and the mean Glasgow Outcome Scale (GOS) of the patients in 2 groups. No significant difference was observed in the duration of mechanical ventilation, hospitalization, and mortality in both groups (P > .05) in ICU. However, there was a significant difference between the mean GCS at the time of admission and discharge and death. Also, significant differences existed between the mean GOS in discharged and deceased patients (P = .001). This study showed no significant difference between the mean GCS at the time of admission and discharge and the mean GOS of the discharged patients and the mortality rate in the 2 groups. However, there were clear statistical differences between these variables in discharged and deceased patients. It is recommended that further studies are conducted with a larger sample size.

Zika virus is an emerging public health threat. The large outbreak related to this infection was first reported in 2007 in Yap Island. This virus is associated with microcephaly, Guillain Barre syndrome and some of the presentations of Zika infection include fever, maculopapular rash, arthralgia, bilateral conjunctivas, headache, arthritis/arthralgia with edema of tiny joints of feet and hands, retro-orbital pain, myalgia, asthenia and vertigo. In most of the cases, the infection is asymptomatic and self-limited. One of the largest known outbreaks of the virus was reported in French Polynesia, south pacific in October 2013. At the beginning of 2016, more than 52 countries have had reported the active transmission of the Zika virus. In general, there are two transmission modes for the Zika infection: Vector-borne transmission and Non-vector-borne transmission. Some diagnostic tests for Zika infection are RT-PCR, ELISA, and PRNT. Up to now, there is no specific antiviral medicine for the treatment of Zika infection and also no vaccine is available for immunization. As far as we know, more than half of the world’s people live in areas where the Aedes mosquito lives. There is a probability occurrence of the Zika virus epidemic at any time and in any place without prior notice in today’s “global village”. Therefore, health systems in all the involved countries should implement better triage and early warning surveillance systems for morbid cases of Zika to prevent large epidemics and the spread of the virus among mosquitoes and finally to avoid its disastrous consequences.

This study aimed to examine the effect of test format on test performance by comparing Multiple Choice (MC) and Constructed Response (CR) vocabulary tests in an EFL setting. Also, this paper investigated the function of gender in MC and CR vocabulary measures. To this end, five 20-item stem-equivalent vocabulary tests (CR, and 3-, 4-, 5-, and 6-option MC) were administered to 243 (132 male and 111 female) pre-intermediate students. Results of the study revealed that MC tests were easier than CR. Results indicated a gender bias, in that, males scored better than females in all versions of MC tests while females outperformed males in CR. The findings implied that testers should consider the effect of test format while assessing vocabulary knowledge and use a combination of test formats (MC and CR) in vocabulary assessment to reduce gender bias and format effect.
