AKT-glycogen synthase kinase 3beta (GSK3beta) signaling is a target of lithium and has been implicated in the pathogenesis of mood disorders and schizophrenia. AKT1 protein level is decreased in the peripheral lymphocytes and brains of schizophrenic patients. The SNP2/3/4 TCG haplotype of AKT1 was associated with schizophrenia in patients with Northern European origin. In the present study, we genotyped five single nucleotide polymorphisms (SNP1-5) of AKT1 gene according to the original study in Iranians comprising of 321 schizophrenic patients and 383 controls, all residing in Mashhad city, Northeastern Iran. Haplotype analysis showed that the frequency of a five-SNP haplotype (AGCAG) was significantly higher in schizophrenic patients (0.068) than that of controls (0.034) (P = 0.03 after Bonferroni correction, OR = 2.04, CI = 1.2-3.4). In stratified analysis by schizophrenia subtypes, the frequency of the same haplotype was significantly higher in disorganized subtype (n = 78, frequency of haplotype=0.081) when compared with normal controls (P = 0.04 after Bonferroni correction, OR = 2.59, CI = 1.3-5.2). Our findings did not confirm the association of AKT1 SNP2/3/4 TCG haplotype with the risk of schizophrenia as reported in the original study but showed the evidence of association with a different haplotype, AKT1 five-SNP AGCAG haplotype, with the risk of schizophrenia in Iranian population.

Background:Thalassemia is an inherited blood disease. It is a serious public health problem throughout the Mediterranean region, the Middle East and the Indian subcontinent, as well as in Southeast Asia.Objectives:Thalassemia is an inherited blood disease. It is a serious public health problem. In this study we assessed psychological aspects in Iranian children and adolescents with thalassemia major.Patients and Methods:In this case-control study sixty healthy subjects aged 7-18 years and Sixty Patients with confirmed diagnosis of major thalassemia were enrolled. After obtaining informed consent from parents of all participating thalassemia patients and healthycontrols, we assessed psychological aspects and quality of life by Pediatric Quality of LifeTM (PedsQL™), Strengths and Difficulties Questionnaires (SDQ), State and Trait Anxiety, Children's Depression Inventory (CDI). Results:The results of this study indicate that there are significant changes in depression, anxiety, QOL and behavioral screening between children with thalassemia major compared with healthy subjects by means of both parents and children reports. According to the results, children with thalassemia major have more psychological problems than healthy ones. Patients with thalassemia have a lower QOL than their peers (P = 0.001), the rate of depression is higher in this group (P = 0.015), Also behavioral problems in these children are more than healthy subjects (P = 0.009).Conclusions:We recommend appropriate treatment and counseling procedures in addition to specific treatment of thalassemia. According to the results we suggest to establish pediatric psychiatric clinics beside thalassemic clinics to cure psychological aspects of the disease.

Background: The relationship between depression and increased oxidative stress is well known. DNA damage by oxidation factors is an important cause of the aging process in psychiatric disorders. Aims: Owing to the scarcity of human studies and high inconsistencies in studies of the effects of antidepressants on DNA damage, the current study was undertaken to investigate the effects of depression and its treatment on DNA damage. Methods: In a 15-week open-label study of citalopram ( n = 25) and sertraline ( n = 20), levels of DNA damage were measured by comet assay, proinflammatory (Interlukin-6 (IL-6)) and oxidative DNA damage (8-hydroxy-2’-deoxyguanosine (8-OHdG)) markers by ELISA, and gene expression of base excision repair enzymes (8-oxoguanine glycosylase (OGG1) and poly (ADP)-ribose polymerase-1 (PARP1)) by quantitative real-time polymerase chain reaction in healthy control patients ( n = 14), with depression at the baseline and the same patients after week 15. Results: DNA damage, 8-OHdG, IL-6 and expression of PARP1 were elevated in patients with depression compared with the healthy controls ( p < 0.001). Selective serotonin reuptake inhibitor (SSRI) therapy could significantly reduce the depression score ( p < 0.01), DNA damage ( p < 0.001), as well as 8-OHdG and IL-6 ( p < 0.0001). Nevertheless, the expression of PARP1 and OGG1 showed no significant changes after treatment. Conclusions: This is the first study on the effect of SSRIs on the DNA damage and some of the repair enzymes in depression. Based on the results, depression can cause increased DNA damage. This damage is followed by activation of compensatory mechanisms whereby the expression of DNA damage repair enzymes is elevated. Finally, the treatment of psychiatric disorder by antidepressants can lower the level of oxidative DNA damage.

BackgroundEmpathy is one of the essential components of physician-patient relationship that has a significant effect on treatment outcomes.ObjectiveThe aim of this study was to assess the empathy score among medical students in Mashhad, Iran.MethodsIn this cross-sectional study in 2015, 624 medical students at Mashhad University of Medical Science (Iran) completed the Jefferson Scale of Physician Empathy (JSPE). Data were analyzed by SPSS ver. 16, using independent-samples t-test, Chi-square, MANOVA, Spearman correlation, and Confirmatory factor analysis.ResultsOf the 38.4% males and 65% females who participated in this study, the mean score of JSPE in the sample was 103.67 (±15.34) which was higher in women than in men. Also, the mean scores for each of the three factors of the scale were calculated. The total empathy score, compassionate care, and taking perspectives among different age groups were significant (p=0.000). Furthermore, students having high interest in their field were more empathic (p=0.008). Empathy of interns in relation to three areas of basic sciences (the first year, the second year and the first half of the third year), physiopathology (the second half of the third year, and the fourth year), and clinical trainings (the fifth year, and the first half of the sixth year), experienced significant reduction (p≤0.001).ConclusionsThis study showed that empathy was higher in women in their first medical year and who were of younger age. The overall rate of empathy in the basic sciences period was more than that in the clinical period. Therefore, the initial exposure to clinical education, especially patient education and empathy, has a very prominent effect on the ability of medical students.
