Emotion regulation and executive functions in adolescents with skin picking disorder
No full textAim This study aimed to investigate emotion regulation difficulties and executive functions of adolescent outpatients with skin picking disorder (SPD). Method Ninety six adolescents with SPD and ninety healthy controls were included in the study. All patients were diagnosed with SPD as per the diagnostic criteria of DSM-5. A battery of tests were implemented to evaluate emotional regulation strategies (i.e. acceptance,), as well as associations between those strategies and executive functions, and clinical variables (anxiety, depressive symptoms, impulsivity and illness characteristics). Results The SPD group had significantly higher scores in inhibition (t = 2.982, p = 0.030), emotional control (t = 2.461, p = 0.016), and planning-organization (t = 2.139, p = 0.038) Multiple linear regression model explained a considerable amount of variance of executive functions in the patient group (Adjusted R-2=66.4%). In the patient group, age at illness-onset and the severity of inhibiton were significantly associated with the disruptions in emotional control functions (For age at illness-onset, beta= -0.45, t=-3.0, p = 0.012 and for BRIEF Inhibition scores, beta = 0.31, t = 2.8, p = 0.008). Conclusion The results of this study suggest that those with SPD have more emotion regulation problems and poorer executive function skills compared to those without SPD. Deficits in emotional control were associated with inhibition process and age-onset of the illness
The association between plasma thyroxine levels and neurocognitive impairment in early-onset schizophrenia and other psychosis spectrum disorders
No full textBackground/aim: Limited studies have delved into the association between thyroid hormones and neurocognition in schizophrenia. We aimed to evaluate the relationship between thyroid hormone levels and neurocognitive functions in patients with schizophrenia and other psychosis spectrum disorders (SSD). Method: A total of 135 patients with early-onset SSD were included in the study. The participants underwent a cognitive assessment. Blood samples were collected to measure serum levels of thyroid-stimulating hormone (TSH), free thyroxine (fT4), and free triiodothyronine (fT3). Subgroup analyses were conducted based on the severity of the psychosis. Findings: The results revealed a significant association between fT4 levels and various cognitive domains, including processing speed, verbal fluency, working memory, verbal learning, verbal memory, and visual memory. However, serum TSH and fT3 levels exhibited no significant association with neurocognitive impairment in adjusted linear regression models. Specifically, the correlation between fT4 levels and global cognition was more pronounced in patients with higher scores. Conclusions: Serum fT4 levels were associated with the performance across various cognitive domains in cases of early-onset psychotic disorders. This correlation was accentuated among patients with higher illness severity. Future studies could focus on the effects of specific pathways that can affect the course and progression of psychosis
Impact of the pandemic on the mental health of children and clinical practice in Turkey: a narrative review with recommendations
Full text linkSocial Information Processing and Executive Functions in Male Children and Adolescents with Internet Gaming Disorder
No full textIn recent years, in addition to its clinical importance, interest in the social-cognitive aspect of internet gaming disorder (IGD) has increased. This study aimed to investigate autistic traits, executive functions, and self-regulation abilities of patients with IGD. Eighty-seven male patients with IGD and eighty-three male healthy controls (HC) were included in the study. All patients were diagnosed with IGD as per the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders-5. Healthy controls without any comorbid psychiatric diagnosis were recruited from the community. The Brief Rating Inventory of Executive Function (BRIEF) and the Social Responsiveness Scale (SRS) were implemented to evaluate autistic traits, executive functions, and self-regulation skills. The Beck Depression Inventory (BDI), Screen for Child Anxiety and Related Disorders and Internet Gaming Disorder Scale-Short-Form were used to evaluate psychopathology. The effect size of the impairments in executive functions and self-regulation skills was large (Cohen's d = 1.0-2.0). IGD groups had higher levels of autistic traits compared to healthy controls (d = 1.0-1.4). The differences in BDI and BRIEF scores remained significant in logistic regression analysis. Age at illness-onset, total severity of anxiety, and autistic traits were found as significant correlates of deficits in executive functions among patients with IGD. The results of this study supported the higher autistic traits and poorer executive function skills of patients with IGD. Deficits in executive functions were associated with autistic traits and younger age-onset of the illness
Low Complement C1q/TNF-related Protein-13 Levels are Associated with Childhood Obesity But not Binge Eating Disorder
No full textOBJECTIVE: C1q/tumor necrosis factor-related proteins (CTRPs) are recently described members of the adipokine family. CTRP-13, a new member of this family, has been shown to increase insulin sensitivity and had an anorexigenic effect on food intake in experimental studies. The aim was to investigate serum CTRP-13 levels in children with obesity, and its relationship with other adipokines, metabolic parameters, or binge eating disorder (BED). METHODS: A cross-sectional study was conducted with 105 pubertal children attending a single center. Clinical (metabolic syndrome, BED) and biochemical (glucose, insulin, lipids, leptin, adiponectin, CTRP-13 levels) parameters were assessed. RESULTS: Sixty children with obesity [24 males (40%); median age 14.7 (13.0-16.4) years] and 45 healthy controls [15 males (33.3%); median age 15.2 (14.1-16.5) years] were included. Serum adiponectin and CTRP-13 levels were significantly lower in children with obesity than controls (7.1 vs 20.1 μg/mL, p<0.001; 64.7 vs 103.8 ng/mL, p<0.001, respectively). CTRP-13 levels correlated negatively with body mass index (Spearman rho=-0.230, p=0.018) and positively with high-density lipoprotein-cholesterol levels (Spearman rho=0.218, p=0.026). There was no significant difference in serum CTRP-13 concentrations in terms of the presence of metabolic syndrome or BED. CONCLUSION: Childhood obesity seems to be causing dysregulation in adipokine production and function, including the down-regulation of CTRP-13. The positive correlation between CTRP-13 and HDL-C levels suggested a possible effect of this adipokine on lipid metabolism. Thus CTRP-13 may be a novel biomarker for dyslipidemia in childhood obesity
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
