Article Abstract
Background: Alexithymia is common in patients with type 2 diabetes mellitus (T2DM). Although the estimated prevalence of alexithymia in patients with T2DM is widely reported, these results have not been synthesized.
Aim: To systematically assess the prevalence and characteristics of alexithymia in patients with T2DM.
Methods: We searched for relevant publications in PubMed, Embase, Web of Science, China Knowledge Resource Integrated Database, Wanfang Database, Chinese Biomedical Database, and Weipu Database. The prevalence of alexithymia, the mean scores, and standard deviations of the total scale of the 20-item Toronto Alexithymia Scale (TAS-20) were pooled using random effects meta-analysis in Stata 13.0, with studies stratified by study location in this meta-analysis.
Results: This meta-analysis included thirteen articles. Pooled prevalence of alexithymia (TAS-20 total scores ≥61) were 43.0% (95%CI 35.0-51.0%), and the prevalence of alexithymia was higher in China (45.0%, 95%CI 36.0-54.0%) compared with non-China (41.0%, 95%CI 29.0-54.0%). The pooled mean score for the TAS-20 total scale was 57.70 (95% CI 55.25-60.15). Leave-one-out analysis showed that none of the studies significantly impacted the overall pooled results.
Conclusions: This meta-analysis indicated a high prevalence of alexithymia in patients with T2DM. Thus, clinicians need to be aware of and assess appropriately for alexithymia in patients with T2DM.
Introduction: The number of insular gyri is elevated in patients with schizophrenia. Thus, it has potential as a marker of early neurodevelopmental abnormalities. However, currently it remains unclear whether patients with other neuropsychiatric disorders, such as affective disorders, also have this gross brain anatomical feature.

Introduction: Knowledge of the symptomatological structure of mental disorders is relevant for their understanding and classification. In the absence of previous Latin American research on the simultaneous structural exploration of various types of psychiatric symptomatologies, the objective of this study is to examine the structure of anxious and mood-related symptoms, resulting syndromes, and their correlations.
Method: Several instruments for the evaluation of anxious, depressive, and manic symptoms were administered to 305 psychiatric outpatients.
Sex differences in schizophrenia have been noted across domains such as alexithymia and cognitive function; however, how they interact remains unclear. This study aimed to explore sex differences in the relationship between alexithymia and cognitive function in patients with chronic schizophrenia. A total of 695 patients (464 males and 231 females) who met the DSM-IV diagnostic criteria for schizophrenia were recruited in this cross-sectional study.
