Serum Cingulin levels are increased in children with autism spectrum disorder.

Background: Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders in which the underlying pathogenesis and etiologic factors are not fully understood. The blood brain barrier (BBB) ​​plays a critical role in central nervous system defense by limiting access to circulating solutes, macromolecules, and cells that can negatively affect neuronal activity. The loss of BBB integrity is likely to be seen as a common pathologic finding for many psychiatric disorders such as schizophrenia, ASD, and mood disorders. In this study, we aimed to investigate whether serum Cingulin levels are associated with ASD. Subjects and Methods: A total of 40 treatment-naive children with ASD and 40 healthy controls were included in the present study. The Schedule for Affective Disorders and Schizophrenia for School-Aged Children, Present and Lifetime Version-DSM-5 (K-SADS-PL-DSM-5) has been used to screen healthy controls for psychiatric disorders by a psychiatrist after a physical examination by a paediatrician. The clinical severity of the ASD symptoms has been assessed by the Childhood Autism Rating Scale (CARS). Venous blood samples were collected and serum Cingulin levels were measured. Results: When the ASD and control groups were compared, CARS and Cingulin values of the patient group were statistically higher than the healthy group. There is a statistically positive correlation between CARS and Cingulin values. Discussion: To the best of our knowledge, this study is a first in the literature conducted about the serum Cingulin levels, which is a component of BBB, among patients with ASD. Our findings demonstrate that serum Cingulin levels are meaningfully higher in ASD group compared to the healthy control group. It has been also indicated that there has been a meaningful relationship between serum Cingulin levels and ASD symptom severity.

Galectin-3 levels in school aged children with autism spectrum disorder.

Objective: Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders with underlying pathogenesis and etiological factors not fully understood. We assumed that galectin-3, which is also linked with inflammatory responses, may be central to the ethiopathogenesis of ASD. Method: The current study consisted of 33 psychotropic medication-naive children with ASD and 32 control subjects. The Schedule for Affective Disorders and Schizophrenia for School-Aged Children, Present and Lifetime Version-DSM-5 (K-SADS-PL-DSM-5) was used to screen healthy controls for psychiatric disorders by a psychiatrist after a physical examination by a pediatrician. The clinical severity of the ASD symptoms has been assessed by the Childhood Autism Rating Scale (CARS). Venous blood samples were collected and serum galectin-3 levels were measured. Results: When the ASD and control groups are compared, the mean galectin-3 level is 417.77 (SD = 200.20) in the ASD group and 243.08 (SD = 64.65) in the control group, and there is a statistically significant difference between the groups (p < 0.001). When examining whether there is a correlation between galectin-3 levels and CARS total scores, no statistically significant correlation was found between them (r = 0.015, p = 0.933). Discussion: In this study, we examined whether serum galectin-3 levels have a relation with ASD in childhood or not. Our findings have indicated that the children with ASD have higher serum galectin-3 levels compared to the controls. However, no significant relationship has been found between serum galectin-3 levels and ASD symptom severity.

THE ASSOCIATION BETWEEN ALTMETRIC, PLUMX METRICS AND CITATION COUNT OF PUBLICATIONS: A CROSS-SECTIONAL STUDY AMONG TOP CHILD AND ADOLESCENT PSYCHIATRY JOURNALS.

BACKGROUND: Altmetric Attention Score (AAS) and PlumX Metrics are becoming important to evaluate the impact of the publication in addition to classical scientific rating method such as citation count and impact factor. These metrics collect data about publications' tweet count, Facebook interaction count and other social interactions. In this study, it is aimed to examine the association between AAS, PlumX Metrics and citation count of top child and adolescent psychiatry. METHODS: We identified the five journals and retrospectively analysed the publications published in 2019. All the original research articles, met analysis, and reviews were analysed. The articles were divided into two groups as original articles/research articles and meta-analysis/systematic review. We have hypothesized that there could be a positive correlation between AAS and PlumX Metrics data and citation count among these journals and there could be a difference between AAS, PlumX scores and citation count between original articles/research articles and meta-analysis/systematic review as their reading potential is different. RESULTS: We have found a significant positive correlation between citation count, AAS and PlumX Metrics. This association continued after controlling the journal impact factor. In linear regression analysis, type of publication, total count of tweets, and Mendeley reads predicted the citation count. CONCLUSION: In addition to the classical methods measuring the quality of the articles such as the total citation count and impact factor, the importance of AAS and PlumX Metrics has been increasing. It is important to share scientific publications on these platforms in order to increase the impact of the articles.

Increased serum levels of tumour necrosis factor-like weak inducer of apoptosis in children with autism spectrum disorder.

Introduction: A previous study has evaluated the association between serum tumour necrosis factor-like weak apoptosis inducer (TWEAK) levels and autism spectrum disorder (ASD). In line with this investigation, the present study aimed to measure serum TWEAK levels to determine whether their eventual alteration might have etiopathogenetic significance in children with ASD. Methods: A total of 40 treatment-naive children with ASD and 40 healthy children as controls were included in the present study. The Schedule for Affective Disorders and Schizophrenia for School-Aged Children-Present and Lifetime Version, DSM-5 was used by a psychiatrist to screen the healthy controls for psychiatric disorders after a physical examination by a paediatrician. The clinical severity of the ASD symptoms was assessed by the Childhood Autism Rating Scale. Venous blood samples were collected, and serum TWEAK levels were measured. Results: This study included 80 children in total, with 40 (50.0%) in the patient group and 40 (50.0%) in the healthy control group. Thirty four (85.0%) of the participants in the patient group, and 31 (77.5%) in the healthy control group, were male, and the remainder were female. The distribution of the gender ratio was statistically similar between groups (p = 0.568). The volunteers were between 36 and 59 months old. The average age in the patient group was 46.0 ± 6.5, while that in the healthy control group was 45.2 ± 6.7. The ages were also statistically similar between groups (p = 0.615). The TWEAK values of the patient group were found to be statistically higher than those of the healthy control group (p < 0.001). Discussion: This study examined whether serum TWEAK levels were related to ASD in childhood. Our findings indicate that children with ASD have higher TWEAK levels when compared to other children. The findings further indicate that serum TWEAK levels could be related to ASD etiopathogenesis independent of ASD symptom severity.

The association between autistic traits and serum testosterone, oxytocin, and androstenedione levels in prepubertal male drug naive children with attention-deficit/hyperactivity disorder.

BACKGROUND: Children with attention-deficit/hyperactivity disorder (ADHD) might have similar problems as in autism spectrum disorder (ASD) and show impairment in social behaviour. Also, there is a relationship between social relationship skills and ToM (theory of mind) skills of children with ADHD. Besides, ASD is associated with prenatal exposure to high levels of androgens, and oxytocin plays a role in the modulation of emotions, coping with stress, and social behaviour like ASD. In this study, the relationship between autistic traits and serum oxytocin, testosterone, and androstenedione levels in prepubertal male drug naive children with ADHD has been investigated. METHOD: Eighty-three prepubertal children, who were diagnosed with ADHD between the ages of 6-10 years old, are included in the study. For the study, intelligence levels were evaluated by using WISC-4, and autistic traits were measured by using both social responsiveness scale and theory of mind tests. In addition, serum oxytocin, testosterone, and androstenedione levels were measured by using ELISA. RESULTS: It has been found that serum testosterone levels of patients with lower autistic traits are significantly lower than those with moderate and severe autistic traits, while the serum oxytocin levels are significantly higher. Also, patients with severe autistic traits have had significantly higher serum androstenedione levels than those with lower and moderate autistic traits. CONCLUSION: This study suggests that patients who have higher autistic traits have elevated testosterone and androstenedione levels and lower serum oxytocin levels. Further studies are needed to clarify this relationship.

Serum Apelin-13 Levels Are Decreased Among Adolescents Diagnosed with Major Depressive Disorder.

BACKGROUND: Apelin-13 have potential effect on mood because of high expression in the hypothalamus. In this study, we aimed to investigate the serum apelin-13 levels among adolescents with major depressive disorder. SUBJECT AND METHODS: A total of 42 patients between the ages of 12 and 18 with a primary diagnosis of major depressive disorder have been included. Depression scores of both groups were measured by the Children's Depression Inventory. Serum apelin-13 concentrations were measured by a commercially available kit based on enzyme-linked immunosorbent assay (ELISA) method. RESULTS: The mean serum apelin-13 levels in the patients with MDD was 173.08±106.33 pg/ml, whereas it was 251.75±167.82 pg/ml in healthy controls. The difference between groups in terms of mean serum apelin-13 levels was statistically significant (p=0.018, Cohen's d=-0.571). CONCLUSION: This is the first study to examine the serum apelin-13 levels in adolescents diagnosed with major depressive disorder. Lower serum apelin-13 levels were found in depressed adolescents.

[Reliability and Validity of the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version, DSM-5 November 2016-Turkish Adaptation (K-SADS-PL-DSM-5-T)]. / Okul Çagi Çocuklari için Duygulanim Bozukluklari ve Sizofreni Görüsme Çizelgesi–Simdi ve Yasam Boyu Sekli–DSM–5 Kasim 2016 –Türkçe Uyarlamasinin (ÇDSG–SY–DSM–5–T) Geçerlik ve Güvenirligi.

OBJECTIVE: The aim of this study was to evaluate the reliability and validity of the Schedule for Affective Disorders and Schizophrenia for School-Age ChildrenPresent and Lifetime Version, DSM-5 November 2016 -Turkish Adaptation (K-SADS-PL-DSM-5-T).  METHOD: A total of 150 children and adolescents between 6 and 17 years of age were assessed with K-SADS-PL-DSM-5-T. The degree of agreement between the DSM-5 criteria diagnoses and the K-SADS-PL-DSM-5-T diagnoses were considered as the measure of consensus validity. In addition, concurrent validity was examined by analyzing the correlation between the diagnoses on K-SADS-PL-DSM-5-T and relevant scales. Interrater reliabilities were assessed on randomly selected 20 participants. Likewise, randomly selected 20 other participants were interviewed with K-SADS-PL-DSM-5-T three weeks after the first interview to evaluate test-retest reliability.  RESULTS: The consistency of diagnoses was almost perfect for eating disorders, selective mutism and autism spectrum disorder (κ=0.92-1.0), substantial for elimination disorders, obsessive-compulsive disorder, oppositional defiant disorder, generalized anxiety disorder, social anxiety disorder, depressive disorders, disruptive mood dysregulation disorder and attention deficit hyperactivity disorder (κ=0.67-0.80). Interrater reliability was perfect for selective mutism (κ=1.0), substantial for oppositional defiant disorder, disruptive mood dysregulation disorder, attention deficit hyperactivity disorder, depressive disorders and social anxiety disorder (κ=0.63-0.73). Test-retest reliability was almost perfect for autism spectrum disorder (κ=0.82), substantial for attention deficit hyperactivity disorder, oppositional defiant disorder, disruptive mood dysregulation disorder, depressive disorders and generalized anxiety disorder (κ=0.62-0.78).  CONCLUSION: The results of this study show that the K-SADS-PL-DSM-5-T is an effective instrument for diagnosing major childhood psychiatric disorders including selective mutism, disruptive mood dysregulation disorder and autism spectrum disorder which have recently been added to the schedule.

[Motor Proficiency in Children with Attention Deficit Hyperactivity Disorder: Associations with Cognitive Skills and Symptom Severity]. / Dikkat Eksikligi Hiperaktivite Bozuklugu Olan Çocuklarda Motor Yeterlilik: Bilissel Beceriler ve Belirti Siddeti ile Iliskisi.

OBJECTIVES: Of children with Attention Deficit Hyperactivity Disorder (ADHD), 45-70% have motor skill problems, which can adversely affect social competence, peer relations, and academic skills. The aim of this study is to assess motor skills in school-aged children with ADHD, and to elucidate if there are any relationships between ADHD symptoms and cognitive function. METHOD: Included in this study were 58 children (38 ADHD, 20 controls) between 8-11 years of age. Children were diagnosed with ADHD via the Schedule for Affective Disorders and Schizophrenia for School-Aged Children Present and Lifetime Version. The parents were asked to fill out the Conner's' Parent Rating Scale - Revised Short Turkish Form to determine the symptom domains and the symptom severity. The Wechsler Children's Intelligence Scale-IV was used to assess cognitive skills, and the Bruininks -Oseretsky Motor Proficiency Test was used to assess motor skills. RESULTS: Children with ADHD had impaired performance in many motor skill areas compared to the controls. Impairments in fine motor skills were correlated with problems in attention, working memory, and processing speed. In the ADHD group, age was not correlated with motor skills enhancement. CONCLUSION: The multistage clinical evaluation of ADHD should include screening for problems in motor skills. If deficiencies are found, the child should be clinically evaluated for motor proficiency and, if necessary, should be referred for appropriate objective assessment and intervention programs.
