Transcranial direct current stimulation (tDCS) is a non-invasive method that improves learning and memory. In this study, the effect of tDCS on streptozotocin (STZ) induced amnesia in the presence or absence of SCH23390 (D1 dopamine receptor antagonist) and sulpiride (dopamine D2 receptor antagonist) has been investigated in male Wistar rats. ⋯ The study showed that D1 and D2 dopamine receptors are involved in the restoration effect of left frontal anodal- but not cathodal-tDCS in STZ-induced amnesia.

Hepatitis C virus (HCV) viremia is described as persistent HCV RNA among HCV exposed individuals. HCV viremic rate is defined as the proportion of anti-HCV positive and HCV RNA positive individuals to total anti-HCV positive individuals. Knowledge about HCV viremic rate increases understanding HCV epidemiology and provides the likelihood of HCV viremia infection in a given population. The aim of this study was to evaluate HCV viremic rate and demographic parameter correlations among HCV confirmed Iranian blood donors. ⋯ The results of this study show the likelihood of active HCV infection occurrence among HCV confirmed Iranian blood donors, as the majority are in the active phase of HCV infection. The viremic rate was associated with first time donation. More effective donor selection process and paying special attention to maintenance of non-infected first time donors as a resource of regular donations are needed to improve blood safety. Follow-up studies on viremic first time blood donors are recommended to clarify impact of factors on the occurrence of HCV viremia.

Mental health is one of the characteristic benchmarks of public health. This research aimed to evaluate mental health of survivors of the Bam earthquake which occurred in 2003 twelve years after the earthquake in fall of 2015. ⋯ The results of this study showed more than half of the Bam earthquake survivors are suspected to be suffering from mental disorders. Since natural disaster-related mental illness effects can last for many years, comprehensive screening programs at regular intervals are required. Mental health services should be available to the elderly and people at risk in order to ensure restoration of mental health after a catastrophe.

Gender identity disorder (GID) is associated with various adverse health outcomes as well as psychiatric problems. Quality of life (QOL) in patients after surgery is an important issue, as some cases report dissatisfaction and regret after surgery. The present study compared QOL in female-to-male (FTM) GID patients before and after gender reassignment surgery (GRS) in an Iranian population. In the present study, 42 natal female patients with Gender Disorder diagnosis, who were referred to the Fertility Research Center of Tehran University of Medical Sciences for GRS from December 2014 to December 2015, were prospectively recruited. ⋯ In conclusion, as the results of the present study highlight, FTM GD patients have a low QOL before surgery that is significantly improved after surgery.

We investigated the association of estimated glomerular filtration rate (eGFR) with Framingham risk score (FRS), and actual cardiovascular disease (CVD) in patients with type 2 diabetes (T2DM). We also assessed improvement in FRS for prediction of CVD after inclusion of eGFR and albuminuria. ⋯ Inclusion of eGFR and albuminuria in the FRS formula did not improve the predictive value of the model. We showed an inverse association between eGFR and FRS in early stages of diabetic kidney disease, which was lost in patients with CKD.
