Objective: Findings about inflammatory processes in schizophrenia are increasing day by day. Inflammatory processes in schizophrenia are associated with both its etiology and clinical symptoms. Serum high-sensitivity C-reactive protein (hsCRP) is also one of these inflammatory processes. Particularly, it is thought to be closely related to clinical findings of patients with schizophrenia. Methods: In this study, the relationship between clinical findings of hsCRP levels of patients with drug-naïve first-episode psychosis (FEP) and patients with schizophrenia in acute exacerbation phase is investigated. Clinical findings, psychometric properties (the Scale for the Assessment of Positive Symptoms, the Scale for the Assessment of Negative Symptoms, Brief Psychiatric Rating Scale), and hsCRP levels of patients were compared. Results: Forty-eight patients with FEP, 74 patients with schizophrenia in acute exacerbation phase and 54 healthy controlled volunteers are included in the study. The most substantial finding in the study is that there is a positive correlation between hsCRP levels and severity of positive symptoms of both patient groups, with FEP and with schizophrenia. The second most substantial finding is there is no significant difference between patients with FEP and schizophrenia, in terms of hsCRP. Conclusion: The relationship between hsCRP and positive symptom severity in two groups of patients supports the inflammatory hypothesis in the etiopathogenesis of schizophrenia. This finding is supportive of close relation between inflammatory processes and clinical findings of patient with schizophrenia.

Objective: Myostatin is a growth factor which is investigated regarding musculoskeletal system. Albeit its effect on muscle mass is known, it is considered likely having other unknown effects as well, particularly on central nervous system. With this study, it is aimed to find out that what type of effect electroconvulsive therapy (ECT) does on myostatin in patients with treatment resistant depression. Methods: Twenty-nine patients with treatment resistant major depression and thirty healthy volunteers were included in the study. Pre- and post-ECT levels of myostatine were compared; also this results were compared to healthy controls. Results: For 29 patients with treatment-resistant major depression, the pre-treatment mean myostatin level was 0.95±0.32 ng/ml and post-therapy myostatin level was 11.05±6.97 ng/ml. As a result of this study, it is found that ECT affects serum myostatin levels to a significant degree (t=4.17, p<0.05). It is also found that there was a significant relation between serum myostatin levels and depression scores (r=0.392, p<0.05). Conclusion: With the present study and similar ones, it can be understood that how ECT achieves its effectiveness biologically.

Objective This study aims to evaluate whether smartphone addiction (SA) is associated with social media use and alexithymia levels in university students.Methods A group of 935 students aged between 18 and 45 years (509 females and 426 males) was recruited from different universities in Istanbul. SAs, alexithymia and social media use were assessed using the Smartphone Addiction Scale Short Version (SAS-SV), Toronto Alexithymia Scale-20 (TAS-20), and ad-hoc questions regarding social media use.Results The mean age of participants was 21.89±3.27 years and 509 of participants were female (54.4%). 455 (48.6%) participants were placed in the “SA” and 198 (21.2%) in the “alexithymia” categories. The study found a high level of positive correlation (p<0.001) between both subscale and total TAS-20 scores and SAS-SV scores. Gender (OR=1.496, 95% CI 1.117–2.002, p=0.007) and number of social media by participants (OR=1.221, 95% CI 1.134–1.315, p<0.001) and TAS (OR=1.074, 95% CI 1.059–1.090, p<0.001) were found to be an independent predictors for SA.Conclusion The study revealed a positive correlation between alexithymia and smartphone use severity, and alexithymia was a significant predictor of SA. Future studies focusing on the causal aspect of this relationship will be useful in planning strategies for treatment.
