Oxidative stress abnormalities have been proposed to explain the pathogenesis of schizophrenia. The present study examined neopterin and oxidative stress abnormalities in schizophrenia patients before and after treatment. Serum neopterin, total anti-oxidants, nitrites and thiols in antipsychotic-naive schizophrenia patients (n = 45) were assessed at baseline before treatment in comparison with healthy controls (n = 43). The schizophrenia patients on treatment were followed up for 3 months and these parameters were reassessed (n = 32). In comparison to healthy controls, schizophrenia patients had significantly higher levels of neopterin and nitrites and significantly lower levels of anti-oxidants before treatment. During follow-up assessments in schizophrenia patients after treatment with antipsychotics, there was a significant decrease in the neopterin levels and significant increase in anti-oxidant levels. Our study observations support increased oxidative stress in schizophrenia that improves with antipsychotic treatment. (C) 2009 Elsevier Ltd. All rights reserved.

Summary: Larger thalamic volume has been found in children with obsessive-compulsive disorder (OCD) and particular subregions may drive these differences. In adults, smaller volumes were observed across all subregions and the whole thalamic volume, mostly driven by medicated patients and associated with symptom severity.

Summary: This study examined the relationship between retinal vascular measures and brain white matter lesions in schizophrenia for the first time. The results showed that retinal vascular tortuosity and fractal dimension were associated with changes in cerebral white matter and may serve as proxy markers for cerebral microvasculature in schizophrenia. These findings could have important clinical implications for screening schizophrenia patients for risk of adverse cerebrovascular events.

Summary: This study aimed to translate neuroimaging findings in neuropsychiatric research to worldwide populations by using a harmonized MRI data acquisition and quality assessment method. The results showed that there was less variation within sites than between sites in terms of image quality measures (IQMs) and outcome measures. IQMs had less of an impact on outcome measures after preprocessing. Continuous monitoring of IQMs per site is valuable to detect potential artifacts and outliers.

Transcranial Alternating Current Stimulation (tACS) and Its Role in Schizophrenia: A Scoping Review

Summary: Transcranial alternating current stimulation (tACS) may alleviate associated symptoms in schizophrenia by modulating neuronal oscillations through sinusoidal alternating current. Preliminary research has shown promising results in the utility of tACS for schizophrenia, particularly in the areas of cognitive deficits and positive symptoms. However, more rigorous randomized controlled trials are needed to substantiate these early findings.

Summary: This study found that there were no differences in age and gender between patients with major depressive disorder (MDD) and healthy controls. The plasma levels of C1q, Factor B, and Factor H were significantly elevated in MDD patients compared to healthy controls. However, these complement proteins were not found to correlate with the clinical profile of MDD patients. These findings suggest that the alternative complement pathway plays an important role in immuno-inflammation in MDD.

Summary: Interoception refers to the perception of signals from inside the body, playing a significant role in various bodily systems. It is closely related to the autonomic nervous system and has gained attention in neuropsychiatric research. Different facets of interoception and their assessments have been proposed, and its dysregulation is implicated in psychiatric disorders. This review aims to provide a comprehensive understanding of interoception, its disturbances, and its impact on psychiatric disorders.

Summary: Antipsychotics are crucial for treating schizophrenia spectrum disorders. Previous research suggests that these medications may lead to weight gain and dyslipidemia, while also improving psychiatric symptoms. This study explores the relationship between glucose parameters and changes in psychopathology, finding that increased glucose and insulin levels after treatment are associated with clinical improvement.

Summary: This study investigates the association between cognitive reappraisal and panic disorder (PD), and finds that PD patients have weakened functional connectivity between the prefrontal cortex (PFC) and the amygdala, which is associated with the severity of PD symptoms. Additionally, cognitive reappraisal is negatively correlated with PD severity, and the PFC-amygdala functional connectivity plays a mediating role in this association.

Summary: Depression and anxiety are prevalent mental disorders among adolescents. The study utilized network analysis to examine the symptom dimension of depression and anxiety in different age groups of adolescents. The results indicated that different age groups have different key symptoms and bridging symptoms, highlighting the importance of targeting specific symptoms at different stages of adolescence in treatment to alleviate the comorbidity of anxiety and depression.

Summary: Major depressive disorder is a prevalent condition worldwide, but the proportion of patients receiving treatment has not increased. Biomarkers related to drug-treatment responses can be used to monitor the effectiveness of medication. Serum protein levels were compared among patients with depression who received medication, those who did not, and a control group. Eight biomarkers were identified, which can be used to monitor the effectiveness of drug treatment.
