    The indexed Iranian journals in ISI and PubMed at the end of 2012 with known impact factor (IF) were evaluated with regard to the number of articles published in 2010-2012, the number of citations by authors from inside and outside Iran, their IF as well as their ranking order among all other journals in their specialized categories. There were among 130 English journals, 21 indexed with known IF. The mean IF of these journals increased from 0.4 in 2010 to 0.68 in 2012. The number of citations per article by authors from outside Iran increased from 0.19 to 0.49 during the same time period.
    The rank of the majority of the indexed journals was in the lowest 20% of their category. Although some improvement has been observed in the quality and the number of citations of Iranian journals indexed in ISI during these two years, the quality of the manuscripts remains low. A reduction in the number of journals, a change of their structure as well as more financial resources for research is necessary for the improvement of the quality and better rank and status of Iranian science among an international audience.

    Glutamate dysregulation may be involved in the neuropathology of schizophrenia. Memantine, a drug approved by the FDA for the treatment of moderate to severe Alzheimer's disease, acts as a partial uncompetitive NMDA receptor antagonist. The aim of this study was to examine the efficacy of memantine as an adjunctive treatment to olanzapine in patients with schizophrenia.
    In this double-blind, placebo-controlled studies, patients with schizophrenia according to DSM-IV clinical criteria were selected. Patients were randomly assigned to receive either memantine (week 1:10 mg/day; weeks 2-6:20 mg/day) plus olanzapine (15-20 mg/day) or olanzapine plus placebo. At baseline, no statistically significant difference regarding the mean total PANSS scores between treatment groups was found. Results showed that memantine significantly improved the positive and negative PANSS score in patients maintained on olanzapine after six weeks compared to olanzapine alone (P

    Helicobacter Pylori infection is a common gastrointestinal infection that can cause pathological effects, increase oxidative stress and induce an inflammatory response in gastric mucosa. Inflammatory aspects may prompt the production of radical oxygen substance (ROS) which may damage cells and release 8-hydroxydyoxyguanosine (8-OHdG) to serum. In this study, we evaluate the prevalence of H. pylori virulence factors and the association between serum level of 8-OHdG, H. pylori infection, and its various virulence factors. The presence of H. pylori and prevalence of cagA, babA and oipA genes in samples were determined by rapid urease test (RUT), histopathological exam (HE) and polymerase chain reaction (PCR) and oxidative DNA damage situation were assessed by using serum level of 8-OHdG. There was not any direct relation between H.
    pylori negative and H. pylori oipA늗鲊枧 by 8-OHdG serum level (P>0.05). In all clinical observations, the presence of cagA and oipA genes was common. There was a statistical relationship between the presence of cagA, babA factors, and high serum level of 8-OHdG (P

    This study investigated efficacy and side effects of Morphine suppository for pain management after the first elective caesarean delivery in comparison to Diclofenac suppository. One hundred women aged 18-40 with term pregnancies undergoing elective caesarean section for the first time participated in this prospective project. Exclusion criteria included drug sensitivity, fetal malformations or defects, and complications during the cesarean operation. After same spinal anesthesia and same surgical techniques and in the recovery room patients consecutively received 100 mg diclofenac suppository or 10 mg morphine suppository. The pain severity was rated by “Numerical Rating Scale.” There was not the difference between two groups in terms of basal information. Pain score was significantly different between two groups in the first 12 hours (5.66 ±1.36 in morphine group and 3.63±0.96 in diclofenac group) but not in the second 12 hour period. Considering pain scores every two hours in first 12 hours and every 4 hours in second 12 hours, morphine group had higher scores in comparison to diclofenac group. Also, the morphine group required pethidine injection sooner than the other group. The time giving first pethidine injection was 3.28±2.16 hours after operation in morphine group and 5.24±4.07 hours after operation (P

    Attention deficit hyperactivity disorder (ADHD) and Anxiety is the most common childhood psychiatric disorder. Based on studies, these disorders are more prevalent in some chronic disease. This study aimed at investigating the prevalence of ADHD and anxiety in children with malignancy and anxiety in their parents and comparing the results with those of the control group. One hundred, 3-15-year-old children with malignancy and 100 healthy children without malignancy or any chronic disease were included in this case-control study as case and control groups, respectively. Subjects were selected from children who were referred to the pediatric ward of Amir Kabir Hospital of Arak, Iran, in the form of simple probability and based on inclusion and exclusion criteria. ADHD and Anxiety were diagnosed by Conner's Parent Rating Scale-48 (CPRS-48) and Hamilton Anxiety Rating Scale (HARS) and were confirmed by psychologist consult. Data were analyzed by Student t-test in SPSS18. ADHD was observed in 23 cases (23%) with malignancy and 5 controls (5%) (P=0.001). In the case group, 57 children (57%) and 45 of their parents (45%) were suffering from anxiety while in the control group the figure was observed in 12 children (12%) and 11 of their parents (11%) (P=0.001). ADHD and anxiety are more common in children with malignancy as compared with children without malignancy and anxiety is also more common in their parents. Therefore, implementing interventions and psychiatric counseling are recommended for these children and their parents.

    The present study aimed to assess changes in resting and maximum heart rates as primary indicators of cardiac autonomic function in metabolic syndrome (MetS) patients and to determine their value for discriminating MetS from non-MetS. 468 participants were enrolled in this cross-sectional study and assessed according to the updated adult treatment panel III (ATP-III) definition of MetS. Resting and maximum heart rates were recorded following the Bruce protocol during an exercise. A receiver operating characteristic (ROC) curve was used to identify the best cutoff point for discriminating MetS from the non-MetS state. 194 participants (41.5%) were diagnosed as MetS. The mean resting heart rate (RHR) was not statistically different between the two groups (P=0.078). However, the mean maximum heart (MHR) rate was considerably higher in participants with MetS (142.37±14.84 beats per min) compared to the non-MetS group (134.62±21.63 beats per min) (P

    Retinal vein occlusion (RVO) is a common retinal vascular occlusive disorder and is associated with a variety of systemic risk factors. The aim of this study was to investigate whether the underlying diseases were evaluated and managed appropriately by ophthalmologists. We performed a study of 1344 patients with retinal vein occlusion (RVO). Patients were evaluated with a questionnaire including ten closed questions to determine whether ophthalmologists evaluated and informed their patients about the underlying systemic diseases. None of the patients’ homocysteine levels were measured. Only a small percentage of the patients were asked about the history of thrombotic diseases or family history of thrombotic diseases. We believe that most ophthalmologists are still not entirely convinced of their responsibility of managing the underlying predisposing factors of RVO. Ophthalmologists should either manage or engage other healthcare providers in the management of RVO to guarantee the patient the best care.

    The concept of blended learning in the field of nursing and medicine has been accepted. Blended learning has been extensively used thanks to the development of communication technologies and the availability of Internet services. Meanwhile, experiences-based research, by all accounts, can help the expansion of such a learning modality. Therefore, this study was designed to explain nursing doctoral students’ experiences of blended learning. To attain this goal, a descriptive phenomenology method was used to illustrate experiences as they are experienced by the participants in the study. With regard to the nature of the investigated phenomena and the existing methods for the inductive analysis, Colaizzi’s method of data analysis was used. The findings of the study led to the discovery of three main themes: "failure", "synergy" and "specific interaction". Each of the themes has been further divided into some sub-themes.

    The brucellosis with multi-organ involvement in a patient with a history of the composite aortic graft (Bentall procedure) and Hepatitis B infection is rare. A 35-year-old man presented to us with fever and loss of consciousness. Four years ago, he was IDU and underwent cardiac surgery because of endocarditis. Recently lumbar spondylodiscitis was diagnosed. The Wright (1/320) and Coombs Wright tests (1/640) were positive. After CNS imaging, lumbar puncture was done. The CSF pleocytosis was lymphocyte dominant. In cardiac echocardiography, large vegetation on prosthetic aortic valve leaflets was seen. The brain MRI was reported abnormal. Treatment of brucellosis started with Ceftriaxone, Doxycycline, Rifampin and Gentamycin. After 4 days, he became oriented, and fever was disappeared then we continued the treatment for 16 days. The patient discharged and followed by daily phone calls. As symptoms of abdominal pain and jaundice were presented on the fifth day, he re-admitted. The patient expired because of hepatorenal and cardiac insufficiency. Drug side effects, activation of Hepatitis B and embolism of cardiac vegetation to other organs were suspected causes of death. We do not suggest medical therapy without cardiac surgery in such cases. When combination therapy is necessary for brucellosis in an HBsAg-positive patient, hepatitis virus activity should be assess by HBV-DNA PCR and the dose of drugs with known hepatotoxic effects such as rifampin and co-trimoxazole should be adjust. Combination therapy with quinolones instead of hepatoxic drugs is one of our suggustions.
