Level of serum thioredoxin and correlation with neurocognitive functions in patients with schizophrenia using clozapine and other atypical antipsychotics
Thioredoxin is a serum antioxidant that has been investigated in the etiology of schizophrenia. The aim of this study is investigating the relationship between serum thioredoxin levels and cognitive functions in acute psychotic episode and remission state patients with schizophrenia; and examining whether there were differences between patients using clozapine and other atypical antipsychotics; including risperidone, olanzapine and amisulpride. This research was performed in schizophrenia patients hospitalized with acute psychotic episode (n=57), reevaluated patients after the initiation of treatment (mean 16 weeks) (n=46), and healthy controls (n=41). Positive and Negative Syndrome Scale, Clinic Global Impressions Scale, Neuropsychologic test battery to assess cognitive performance, and serum thioredoxin levels measured by ELISA were used in this research. Serum thioredoxin levels were highest in acute psychotic episode, lower in the remission state and the lowest in healthy controls. Significant correlation has been established between serum thioredoxin levels and Trail Making Test-A performance in remission state patients. In conclusion, serum thioredoxin levels were increased in acute psychotic episode and decreased in remission state, and its relationship with attention is worth to consider in schizophrenia patients
Evaluation of Depression, Anxiety, and Sexual Function in Rectal Cancer Patients Before and After Neoadjuvant Chemoradiotherapy
ObjectiveThe association of treatment-related side effects and tumor characteristics with sexual function, depression, and anxiety were investigated in patients with locally advanced rectum cancer (LARC) receiving neoadjuvant chemoradiotherapy (CRT).Material and MethodsThirty-two patients who received neoadjuvant CRT with LARC were included. The Arizona Sexual Experiences (ASEX) Scale was used to determine the sexual function status whereas the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI) were used to evaluate the depression and anxiety status of the patient, respectively. The patients were asked to fill these scales before and at least 4 weeks after the neoadjuvant CRT. T-test and Mann-Whitney U test were used for the comparison of values.ResultsMedian age was 52.5 years (range: 33-76). Twenty-six patients were male, and 6 patients were female. At presentation, the tumor was located mostly in lower third rectum (72%), and 69% of the patients had T3 tumors. There was a statistically significant deterioration in the sexual functions of the patients (p < 0.001), a statistically significant decrease in their anxiety level after CRT (p: 0.037). Depression level was changed from mild to minimal during this process (p: 0.17). A significant deterioration in the ASEX scale was observed especially in patients with grade 2 and above gastrointestinal side effects (p: 0.01).ConclusionThis prospective study showed that the patient's anxiety and depression levels had decreased during the treatment process probably due to the decrease in the patient's symptoms. However, deterioration of the sexual function status which might be correlated to increased gastrointestinal side effects during CRT has been observed. So, clinical and psychiatric support including therapies for sexual dysfunctions is needed for LARC patients during and after the neoadjuvant CRT
