functional outcome in late adolescence/early adulthood of patients with autism spectrum disorder and its relationships with parental burnout and depression: A preliminary multi-center, cross-sectional study.

The aim of this study is to determine the functioning of adults with autism spectrum disorders (ASDs) diagnosed in childhood and depression and burnout levels among their parents. A total of 261 adults with ASDs and their parents were recruited for the study. Both parents completed the Beck Depression and Maslach Burnout Inventories and reported the functioning of their adult offspring with ASDs. Only 5.4 % of our sample reported "good" or "very good" outcomes. The most common psychiatric comorbidities were intellectual disabilities and attention-deficit/hyperactivity disorder. Maternal burnout and depression scores were significantly elevated compared to those of fathers. There is an undeniable urgent need for more research to identify the needs of adults and families suffering from ASD. Modifications for those with ASD may have to be made for support in workplaces, achieving driving licenses, using public transportation and attendance at tertiary education.

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.

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.

Evaluation of Anxiety Sensitivity, Anxiety, Depression, and Attention Deficit Hyperactivity Disorder in Patients with Tinnitus.

Context: There may be a connection between tinnitus, a common disease in society, and psychiatric disorders. When the literature is reviewed, it has been realized that more data are needed to elucidate this issue. Aims: The aim of this study is to compare the symptoms of anxiety sensitivity, anxiety, depression, and attention-deficit/hyperactivity disorder (ADHD) symptoms in patients with tinnitus with healthy individuals and to investigate the relationship between tinnitus and psychiatric disorder symptoms. Settings and design: This study was designed as a case-control study. Materials and methods: Fifty-one patients with tinnitus and 51 healthy controls were enrolled in this study. Clinical severity of the psychiatric variables were evaluated by Beck depression inventory, Beck anxiety inventory (BAI), anxiety sensitivity index-3, and adult ADHD self-report scale (ASRS) in patient and control groups. Statistical analysis used: Variables are presented as either a number, a percentage, a mean ± standard deviation, or frequency. Chi-squared, Student t tests, and logistic regression analysis were used to examine the relationship between variables. Results: Logistic regression analysis results indicated that a significant predictive power of BAI for the presence of tinnitus. Based on a backward-elimination regression analysis, ASRSs (inattention subscale scores) were considered to predict a higher tinnitus handicap inventory score. Conclusion: These findings provide additional evidence that anxiety and attention-deficit (inattentive) symptoms could contribute to the pathophysiology of tinnitus.

Serum Claudin-5, but not Zonulin, May Be Associated with Obsessive-Compulsive Disorder.

BACKGROUND: The aim of this research was to assess serum zonulin and claudin-5 concentrations to show whether or not their eventual changes in patients with obsessive-compulsive disorder (OCD) could have etiopathogenetic importance. There was no research in the literature assessing serum zonulin and claudin-5 levels in OCD to the best of our understanding. SUBJECTS AND METHODS: In this study, we assumed that there may be a deterioration in serum zonulin and claudin-5 levels in OCD patients and this may affect the severity of the disease. Thirty-six OCD patients and 35 healthy controls were included in this study. The patients were administered Hamilton Depression Rating Scale (HDRS) and Yale-Brown Obsession Compulsion Scale (Y-BOCS) to determine the severity of depression and OCD, respectively. Venous blood samples were collected, and serum zonulin and claudin-5 levels were measured. RESULTS: The mean serum claudin-5 level was significantly higher without a significant difference between age, sex, and body mass index, whereas serum zonulin level was not different from the control group in OCD patients. CONCLUSIONS: In conclusion, the current research indicates that claudin-5 is enhanced in OCD patients and this finding may contribute to the role of blood-brain barrier in the pathogenesis of OCD.

Serum Tumor Necrosis Factor-Like Weak Inducer of Apoptosis (TWEAK) Levels Are Decreased in Children with Attention-Deficit/Hyperactivity Disorder.

INTRODUCTION: There has been no study in the literature evaluating serum tumor necrosis factor-like weak inducer of apoptosis (TWEAK) levels in attention-deficit/hyperactivity disorder (ADHD). Therefore, we performed the present study to specifically measure serum TWEAK levels to see whether or not its eventual alterations might have an etiopathogenetic significance in children with ADHD. SUBJECTS AND METHODS: A total of 49 treatment-naive children with ADHD and 39 healthy controls were included in the present study. The severities of ADHD and conduct disorder symptoms were assessed via parent- and teacher-rated questionnaires. Venous blood samples were collected, and serum TWEAK levels were measured. RESULTS: Serum TWEAK levels of the ADHD group were significantly lower than the control group. CONCLUSIONS: This study shows that ADHD patients have decreased serum TWEAK levels, suggesting a possible involvement of TWEAK in the etiopathogenesis of ADHD.

Investigation of quality of life in obese adolescents: the effect of psychiatric symptoms of obese adolescent and/or mother on quality of life.

OBJECTIVES: The present study assessed the obese adolescents' health-related quality of life (HRQoL) based on both adolescent-reported and maternal-reported questionnaires to clarify adolescent-related psychiatric factors, maternal psychiatric factors, and body mass index (BMI) percentile variables that independently affect the quality of life (QoL). METHODS: A total of 190 adolescents (120 females and 70 males) were included in the study. The impact of clinical and psychiatric factors on the Pediatric Quality of Life Inventory-Child Version (PedsQL-C) scores was analyzed using hierarchical linear regression methods. RESULTS: The final models showed that only the Revised Child Anxiety and Depression Scale-Child Version major depressive disorder scores negatively predicted the physical, psychosocial, and total health scores of the PedsQL-C. The psychosocial scores of the PedsQL-P were negatively predicted by the Strengths and Difficulties Questionnaire emotional, and Conners' Parent Rating Scale-Revised-Short Form (CPRS-R-S) attention-deficit/hyperactivity disorder (ADHD) index scores. The PedsQL-P total scores were negatively predicted by the CPRS-R-S ADHD index scores. CONCLUSIONS: The findings of this study indicate that the adolescents' psychiatric symptoms and BMI percentile played a significant role in the PedsQL subscale functioning of obese adolescents compared to maternal psychiatric symptoms.

Investigation of the psychiatric factors that determine the fear of COVID-19 in healthcare workers and hospital staff in a university hospital in Turkey.

To examine the association of health and hospital workers' fears of coronavirus disease 2019 (COVID-19) with anxiety, anxiety sensitivity, depression, and sociodemographic variables during the COVID-19 pandemic. A total of 527 participants (237 men/289 women) were included, 222 of the participants were doctors, 99 nurses, 22 assistant health personnel, and 182 hospital personnel without health education. Participants filled in the sociodemographic data form, Beck Depression Inventory, Beck Anxiety Inventory, Anxiety Sensitivity Index-3, and Fear of COVID-19 Inventory. In linear regression analysis, independent predictors of the fear of COVID-19 were determined as Beck Anxiety Inventory (p < 0.001), Beck Depression Inventory (p = 0.001), and Anxiety Sensitivity Index-3 Physical subscale (p = 0.001). The fear of COVID-19 is associated with the physical subscale of anxiety, depression, and anxiety sensitivity.

Serum tumor necrosis factor-like weak inducer of apoptosis levels are elevated in schizophrenia

Objective: The purpose of this study was to assess serum Tumor necrosis factor-like weak inducer of apoptosis (TWEAK) concentrations to determine whether changes in patients with schizophrenia could have etiopathogenetic importance. Since very little research has addressed the connection between the inflammatory marker TWEAK and schizophrenia, we wanted to examine alterations of TWEAK and investigate the possible correlation between clinical symptomatology and serum concentrations. Methods: A total of 45 schizophrenia patients and 40 healthy controls were included in this study. The Positive Symptom Assessment scale and the Negative Symptom Assessment scale were administered to determine symptom severity. Venous blood samples were collected and serum TWEAK levels were measured. Results: Serum TWEAK levels were significantly higher in the schizophrenia group than the control group, independently of potential confounders, including sex, age, body mass index and smoking status. Conclusion: The results indicate that TWEAK is elevated in schizophrenia patients, which could deepen our understanding of the role of inflammation in the pathogenesis of schizophrenia.

Comparison of Serum VEGF, IGF-1, and HIF-1α Levels in Children with Autism Spectrum Disorder and Healthy Controls.

The aim of this study was to determine whether serum VEGF, IGF-1, and HIF-1α levels differed between Autism Spectrum Disorder (ASD) patients and healthy controls. A total of 40 children with ASD and 40 healthy controls aged 4-12 years were included. Serum levels of VEGF, IGF-1, and HIF-1α were measured using commercial enzyme-linked immunosorbent assay kits. Serum IGF-1 levels were found to be statistically significantly higher in the ASD group than in the control group. Serum HIF-1α levels were borderline significantly lower in the ASD group. There was no statistically significant difference in serum VEGF levels between the two groups. IGF-1 and HIF-1α may play a potential role in the etiopathogenesis of ASD.

Serum zonulin and claudin-5 levels in patients with schizophrenia.

The aim of this research was to assess whether or not changes in the concentrations of serum zonulin and claudin-5 in patients with schizophrenia could have etiopathogenetic importance. In previous studies, the data regarding the relationship between intestinal and blood-brain barrier (BBB) permeability and the etiology of schizophrenia have been limited. In this study, we assumed that there may be a difference in serum zonulin and claudin-5 levels in patients with schizophrenia, which may affect the severity of the disease. Fifty schizophrenia patients and 50 healthy controls were included in this study. The patients were administered the Positive Symptoms Assessment Scale (SAPS) and Negative Symptoms Assessment Scale (SANS) to determine the severity of symptoms. Venous blood samples were collected, and the serum zonulin and claudin-5 levels were measured. The mean serum zonulin levels were significantly increased in patients with schizophrenia when compared to the control group. Serum claudin-5 levels were decreased in the schizophrenia patients when compared to the controls. The present study indicates that zonulin is increased and claudin-5 is decreased in patients with schizophrenia. These findings extend the existing knowledge on the dysregulation of intestinal permeability, especially zonulin, and BBB, especially claudin-5, and show that both proteins may be involved in the etiopathogenesis of schizophrenia.

Venous blood samples were collected and serum TWEAK levels were measured. RESULTS: Serum TWEAK levels were significantly higher in the schizophrenia group than the control group, independently of potential confounders, including sex, age, body mass index and smoking status. CONCLUSION: The results indicate that TWEAK is elevated in schizophrenia patients, which could deepen our understanding of the role of inflammation in the pathogenesis of schizophrenia.

Serum zonulin and claudin-5 levels in children with attention-deficit/hyperactivity disorder.

OBJECTIVE: This study aimed to investigate serum zonulin and claudin-5 levels of children and adolescents with attention-deficit/hyperactivity disorder (ADHD) and healthy controls by controlling the parameters such as age, sex and body mass index (BMI) percentile which are known to affect these parameters. METHOD: A total of 80 treatment-naive children and adolescents with ADHD and 40 healthy volunteer controls aged 8-12 years were enrolled in this study. The severities of ADHD symptoms were assessed via parent- and teacher-rated questionnaires. The severity of anxiety and depression symptoms of the children were assessed by the self-report inventories. Serum levels of zonulin and claudin-5 were measured using commercial enzyme-linked immunosorbent assay kits. RESULTS: The multivariate analysis of covariance (MANCOVA) revealed a significant main effect of groups in the serum zonulin and claudin-5 levels, an effect that was independent of age, sex and BMI percentile. Significant differences were found between the study groups in terms of serum log-claudin-5 levels. However, there was no significant difference between the study groups in terms of serum zonulin levels. CONCLUSION: These findings provide additional evidence for dysregulation of the blood-brain barrier, especially abnormalities in claudin-5 function, which may be involved in the aetiology of ADHD.Key pointsADHD is one of the most common neurodevelopmental disorders of childhood. Although ADHD is quite common, its aetiology has yet to be fully explained.In recent years, studies on the relationship between intestinal and blood-brain brain barrier permeability and psychiatric disorders have increased.In our study, serum claudin-5 levels were higher in the ADHD group compared to the control group, while serum zonulin levels did not differ between the groups.

Empathy, Alexithymia, and Theory of Mind in Borderline Personality Disorder.

The purpose of this research was to determine the differences in empathy, alexithymia features, and theory of mind between healthy controls and patients with borderline personality disorder (BPD). Thirty-five patients with BPD and 35 healthy controls were included in the study. To measure the clinical variables, the Empathy Quotient (EQ), Reading the Mind in the Eyes Test (RMET), Toronto Alexithymia Scale (TAS-20), Barratt Impulsivity Scale-11 (BIS-11), and Beck Depression Inventory (BDI) were applied. We found that the BPD group had significantly worse total RMET and neutral RMET scores than the control group. There were no differences in the EQ scores between the BPD and control groups. The patients with BPD were more alexithymic than the controls, and alexithymia and depression scores predicted BPD status. Patients with BPD who have difficulty identifying their own emotions tend to display deficits in perceptions of facial emotions, which, in turn, may lead to misperceptions of social signals and thus contribute to excessive emotional intensity and tension in social situations. The study results reveal that alexithymia and depression are important variables in predicting BPD traits.

The Relationship between Second-to-Fourth Digit Ratios, Attention-Deficit/Hyperactivity Disorder Symptoms, Aggression, and Intelligence Levels in Boys with Attention-Deficit/Hyperactivity Disorder.

OBJECTIVE: Observations of sex differences have led some scientists to doubt whether the neuroendocrine system is involved in attentiondeficit/hyperactivity disorder (ADHD) etiology. One of the interesting study subjects in this context is prenatal steroid hormone exposure. The aim of the present study was to replicate and extend previous work by addressing two research questions: 1) Are second-tofourth digit (2D:4D) ratios lower in ADHD than in controls? 2) Is there a correlation between 2D:4D ratios and symptoms of ADHD, aggression and intelligence scores in boys with ADHD? METHODS: The study included 100 treatment-naive male children diagnosed with ADHD and 55 healthy male children. We measured the ratios of 2D:4D and administered a Wechsler Intelligence Scale for Children-Revised to assess IQ scores, as well as behavioral rating scales, in children with ADHD and comparison individuals. RESULTS: We observed lower 2D:4D ratios in the right hand in ADHD in comparison to the control group. The left-hand ratios of 2D:4D, however, did not differ between ADHD and control groups. There were negative correlations between the left-hand 2D:4D ratios and the hyperactivity scores. However, no significant correlation was detected between right-hand 2D:4D ratios and the psychological questionnaire scores. CONCLUSION: These results provide further evidence that fetal androgen exposure may contribute to the pathophysiology of ADHD, at least in boys.

Assessment of intraocular pressure, macular thickness, retinal nerve fiber layer, and ganglion cell layer thicknesses: ocular parameters and optical coherence tomography findings in attention-deficit/hyperactivity disorder

Objective: To compare intraocular pressure (IOP) and macular, retinal nerve fiber layer (RNFL), and ganglion cell layer (GCL) thicknesses in treatment-naive children with attention-deficit/hyperactivity disorder (ADHD), children with ADHD on regular methylphenidate (MPH) treatment for at least 3 months, and healthy controls. Methods: A total of 58 treatment-naive children with ADHD, 45 children with ADHD on regular MPH treatment, and 44 healthy controls were enrolled in this study. All participants underwent a comprehensive eye examination. Optical coherence tomography (OCT) was used to assess global RNFL thickness, central macular thickness, and GCL thickness in both eyes. Results: Separate univariate analysis of covariance (ANCOVA) on the outcome variables revealed a significant difference among the research groups with respect to IOP in the left eye. Post-hoc univariate analyses indicated that left IOP was significantly higher in children with ADHD under MPH treatment than among healthy controls. However, global RNFL thickness, central macular thickness, and GCL thickness of both eyes, as well as IOP in the right eye, were not significantly different across groups. Conclusion: Further longitudinal follow-up studies are needed to determine whether MPH treatment has any effect on IOP or OCT findings.

Serum galectin-3 levels are decreased in schizophrenia.

OBJECTIVE: To determine whether changes in serum galectin-3 (gal-3) concentrations in schizophrenia patients have etiopathogenetic importance. Since very little research has assessed the connection between galectins and schizophrenia, we wanted to examine alterations in the inflammatory marker gal-3 in schizophrenia and investigate possible correlations between clinical symptomatology and serum concentrations. METHODS: Forty-eight schizophrenia patients and 44 healthy controls were included in this study. The Scale for the Assessment of Positive Symptoms (SAPS) and the Scale for the Assessment of Negative Symptoms (SANS) were administered to determine symptom severity. Venous blood samples were collected, and serum gal-3 levels were measured. RESULTS: Mean serum gal-3 levels were significantly lower in schizophrenia patients, and there were no significant differences in age or sex with the control group. There was also a significant positive correlation between serum gal-3 concentrations and negative schizophrenia symptoms according to the SANS. CONCLUSION: The results indicate that gal-3 is decreased in schizophrenia patients, which could contribute to inflammation in the pathogenesis of schizophrenia.

Serum Galectin-3 Levels in Children with Attention-Deficit/Hyperactivity Disorder.

OBJECTIVE: Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder with underlying pathogenesis and etiological factors not fully understood. We assumed that galectin-3, which is also linked with inflammatory responses, may play an important role in the ethiopathogenesis of ADHD. In this study, we aimed to investigate whether serum galectin-3 levels are related to ADHD in childhood. METHODS: The current study consisted of 35 treatment-naive children with ADHD and 35 control subjects. The severities of ADHD and conduct disorder symptoms were assessed via parent- and teacher-rated questionnaires. The severity of anxiety and depression symptoms of the children were determined by the self-report scale. Venous blood samples were collected and serum galectin-3 levels were measured. RESULTS: The ADHD group had significantly higher serum Galectin-3 levels than the control group. To control confounding factors, including age, sex, and BMI percentile, one-way analysis of covariance (ANCOVA) test was also performed. Analyses revealed a significantly higher serum log- Galectin-3 levels in children with ADHD compared to controls. No association was found between the mean serum galectin-3 levels and sociodemographic characteristics and clinical test scores, except the oppositional defiant behavior scores. CONCLUSION: Our research supports the hypothesis that serum levels of galectin-3 might be related to ADHD.

Comparison of the Sleep Problems Among Adolescents Who Attempted Suicide and Healthy Adolescents.

The aim of this study was to compare sleep problems among adolescents who attempted suicide and healthy adolescents who never attempted suicide. Adolescents who attempted suicide (study group, n = 103) and healthy adolescents (control group, n = 59) completed a questionnaire prepared by researchers including demographic factors. In addition, the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) were administered to both groups. The median age was 16 years and 73% were girls, in both groups. The study group had lower rate of attending to school (88.3% vs. 100%; p = 0.001), academic achievement (45.7% vs. 83.1%; p = 0.001), higher rate of smoking (37.9% vs. 13.8%; p = 0.001), socializing problems (31.1% vs. 3.4%; p = 0.001), and appetite changes (57.3% vs. 39.7%; p = 0.032) than controls. The rate of those with PSQI scores 6 or higher was 53.4% in the attempted suicide group and 37.3% in the control group (p = 0.048). Adolescents, classified as sleepy according to the ESS, did not differ significantly between the groups (p = 0.214). Adolescents who attempted suicide had poor sleep quality. It is crucial to examine the kinds of sleep problems adolescents who have attempted suicide have experienced. Among adolescents attending outpatient clinics with poor sleep quality, PSQI can be a useful screening tool. Those with high scores should be evaluated for suicide risk.

Autistic Traits in Men With Substance Use Disorder.

There has been no study in the literature evaluating autistic traits (ATs) in men with substance use disorders (SUDs). Therefore, we performed the current study to evaluate whether there is a relation between the ATs among men with SUDs and normal controls. A total of 142 men with SUDs and 109 age and sex-matched healthy controls were included in the current study. Present attention deficit hyperactivity disorder (ADHD) symptoms of the participants were evaluated using the Adult ADHD Self-Report Scale. The autism spectrum quotient (AQ) was used to evaluate ATs. The current study found that higher AQ imagination and lower AQ attention to detail scores predicted SUDs after controlling for AQ subscales and present ADHD symptoms. This study shows that ATs may be engaged in the development of SUDs. To explore the connection between ATs and SUDs, more research is needed.
