Dynamic changes in the food-cue processing of obese adolescents: A controlled eye-tracking study from a dual-system perspective.

Adolescent obesity is a growing global health problem. Studies have demonstrated that exposure to food cues plays a role in both the development and the persistence of obesity. Understanding how visual attention changes dynamically in response to food cues may explain how they contribute to obesity. The primary aims were to evaluate attentional bias for food cues and conduct a time-course analysis of obese adolescents' food-cue processing. We also investigated the roles of inhibition, cognitive flexibility, and eating styles in their visual attention to food stimuli. A total of 60 age- and gender-matched 12-16-year-olds (n = 30, obese group; n = 30, control group; M = 13.9 years, SD = 1.26) were included in this study's sample. The participants viewed a series of high-calorie and low-calorie food images along with nonfood images in the free exploration paradigm during eye-tracking. Time-course analysis of the proportion of fixations on images of food and high-calorie foods determined that the attentional processing of the two groups differed, especially in later stages. The obese group had higher Stroop Interference and Trail Making Test-B scores than the control group, but these executive functions' scores did not affect their proportions of fixations on food and high-calorie food images over time. Higher Perceptual Reasoning Index scores led to a decrease in the proportions of fixations on high-calorie food images over time in the obese group, and this was particularly noticeable after about 4000 ms. This study found that time-course analysis of visual attention to food cues allows us to understand how it changes dynamically over larger time intervals. Future studies should provide knowledge about maintained attention for food cues and their relationship with top-down factors in obese adolescents.

Novel alterations of CC2D1A as a candidate gene in a Turkish sample of patients with autism spectrum disorder.

BACKGROUND: Autism spectrum disorder (ASD) is a neurodevelopmental disorder with large genetic background, but identification of pathogenic variants has proceeded slowly because hundreds of loci are involved in this complex disorder. CC2D1A gene firstly associated with the intellectual disability (ID) in a family with a large deletion. We aimed to contribute to the literature by sequencing this gene and by this way we report novel CC2D1A variations in patients with ASD. METHODS: Forty families who have a child with a diagnosis of ASD were enrolled to the study. DNA samples were obtained from each family member. Bidirectional CC2D1A gene sequencing was performed with CEQ Cycle Sequencing Kit, and the products were analyzed on the Beckman CEQ 8000. All of the genetic analysis was conducted in Erciyes University Genome and Stem Cell Center (GENKOK). RESULTS: According to the sequencing results, we defined new alterations in this gene with two SNPs in exon 15 and 19 (rs747172992 and rs1364074600) in our patients. We found a pathogenic variant in one patient. This variant was located in the acceptor region. Six of the variants were missense mutations. Additionally, six different benign variants were detected in 30 patients; however, they were not associated with ASD. Two patients carried multiple rare variants. CONCLUSION: In vitro and in vivo functional analysis with this gene will help to understand its contribution to ASD pathogenesis. Future studies may help to elucidate the underlying biological mechanisms of these variants leading to the autism phenotype.

How does adolescent motherhood affect mother-infant/toddler relationship and emotional availability.

BACKGROUND: The present study examined the different aspects of infant-mother relationships in adolescent mothers and compared them in adult mothers. METHODS: Children aged 18-40 months who were referred to our outpatient Infant Mental Health Department were analysed retrospectively. Sociodemographic data, Parent-Infant Relationship Global Assessment Scale (PIR-GAS) scores, and Emotional Availability (EA) Scales scores were analysed. Twenty-nine adolescent mothers being younger than 20 years at the beginning of pregnancy and thirty mothers who were aged at least 25 years were enrolled the same data as adult mother group. RESULTS: In the adolescent mothers group, the education years of the mothers, the ratio of mothers having professions were significantly lower (p < 0.001); the spousal age gap was significantly higher than among the adult mothers (p < 0.001). It was also found that an underinvolved relationship pattern was seen more frequently among the mother-infant dyads in the adolescent mothers' group than in the adult mothers group (p = 0.002). CONCLUSIONS: Although there were not found many problems in terms of the relationship of adolescent mothers with their infants/toddlers in the current study this may have been due to a small sample, we would like to emphasise that the problems should be detected and appropriate interventions should be made for adolescent mothers.Key pointsOur main aim for this study was assesment of the effect of adolescent motherhood in terms of infant\toddler-mother relationshipOur findings showed that lower education level and being unemployed were higher in adolescent mothers group.Higher age gap between spouses was found to be associated with adolescent motherhood. Underinvolved relationship was highly prevalent among adolescent mothersOur findings suggest that early motherhood is a risk factor for mother-infant\toddler-relationship and parenthood.Intervention and education programs during and after pregnancy for adolescent girls may help them to prepare for motherhood more consciously and form established relationships with their infants.

The prevalence of childhood psychopathology in Turkey: a cross-sectional multicenter nationwide study (EPICPAT-T).

AIM: The aim of this study was to determine the prevalence of childhood psychopathologies in Turkey. METHOD: A nation-wide, randomly selected, representative population of 5830 children (6-13 years-old) enrolled as a 2nd,3rd or 4th grade student in 30 cities were evaluated for presence of a psychiatric or mental disorder by a Sociodemographic Form, Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL), and DSM-IV-Based Screening Scale for Disruptive Behavior Disorders in Children and Adolescents scales. Impairment criterion was assessed via a 3 point-Likert scale by the parent and the teacher independently. RESULTS: Overall prevalence of any psychopathology was 37.6% without impairment criterion, and 17.1% with impairment criterion. Attention-deficit hyperactivity disorder was the most frequent diagnosis, followed by anxiety (19.5% and 16.7% without impairment, 12.4% and 5.3% with impairment, respectively). Lower education level and presence of a physical or psychiatric problem of the parents were independent predictors of any psychopathology of the offspring. CONCLUSION: This is the largest and most comprehensive epidemiological study to determine the prevalence of psychopathologies in children and adolescents in Turkey. Our results partly higher than, and partly comparable to previous national and international studies. It also contributes to the literature by determining the independent predictors of psychopathologies in this age group.

Increased vitamin D receptor gene expression and rs11568820 and rs4516035 promoter polymorphisms in autistic disorder.

Although there are a large number of sequence variants of different genes and copy number variations at various loci identified in autistic disorder (AD) patients, the pathogenesis of AD has not been elucidated completely. Recently, in AD patients, a large number of expression array and transcriptome studies have shown an increase in the expression of genes especially related to innate immune response. Antimicrobial effects of vitamin D and VDR are exerted through Toll-Like-Receptors (TLR) which have an important role in the innate immune response, are expressed by antigen presenting cells and recognize foreign microorganisms. In this study, age and gender matched 30 patients diagnosed with AD and 30 healthy controls were included in the study. Comparatively whole blood VDR gene expression and rs11568820 and rs4516035 SNP profile of the promoter region of the VDR gene were investigated by real time PCR. Whole blood VDR gene expression was significantly higher in the AD group compared to control subjects (p < 0.0001). There were no significant differences among allele and genotype distribution of rs11568820 and rs4516035 polymorphisms between AD patients and controls. The increase of VDR gene expression in patients with AD may be in accordance with an increase in the innate immune response in patients with AD. Furthermore, this study will stimulate new studies in order to clarify the relationship among AD, vitamin D, VDR, and innate immunity.

A Case of Child Physical Abuse With a Rolling Pin Insertion, Resulting in Bladder and Rectal Perforation.

Visceral injuries are not uncommon in nonaccidental trauma and often require emergent operative intervention. However, sometimes it can be difficult to assess the extent of injury. In this report, we present a case of child physical abuse resulting in bladder and rectal perforations, which was initially referred to our hospital as acute abdomen with intraperitoneal free fluid on ultrasonography. An exploratory laparotomy revealed the perforations and surgical repair was performed. The patient was evaluated by the Hospital Child Protective team and it was revealed that bladder and rectum perforations were due to insertion of rolling pin into the rectum by the stepmother. The child was discharged home uneventfully with a temporary colostomy. We believe that this is the first reported case in the English literature of inflicted perforation of the rectum and bladder through insertion of a rolling pin.

Association of Reactive-Proactive Aggression and Anxiety Sensitivity with Internalizing and Externalizing Symptoms in Children with Attention-Deficit/Hyperactivity Disorder.

This study evaluates the associations among the symptoms of anxiety, depression, and disruptive behavioral disorders (DBD) in the context of their relationships with reactive-proactive aggression and anxiety sensitivity in children with attention-deficit/hyperactivity disorder (ADHD). The sample consisted of 342 treatment-naive children with ADHD. The severity of ADHD and DBD symptoms were assessed via parent- and teacher-rated inventories. Anxiety sensitivity, reactive-proactive aggression and severity of anxiety and depression symptoms of children were evaluated by self-report inventories. According to structural equation modeling, depression and anxiety scores had a relation with the DBD scores through reactive-proactive aggression. Results also showed a negative relation of the total scores of anxiety sensitivity on DBD scores, while conduct disorder scores had a positive relation with anxiety scores. This study suggests that examining the relations of reactive-proactive aggression and anxiety sensitivity with internalizing and externalizing disorders could be useful for understanding the link among these disorders in ADHD.

The relationship between aggression, empathy skills and serum oxytocin levels in male children and adolescents with attention deficit and hyperactivity disorder.

Although attention deficit and hyperactivity disorder (ADHD) are recognized as neurodevelopmental disorders characterized by impairment in executive functions, impairments in social functioning are often accompanied by ADHD. Oxytocin (OT) has been investigated in a number of psychiatric disorders owing to its effects on social interactions. The aim of this study was to determine the relationship between aggression, empathy and OT levels in children with ADHD. Forty male patients with ADHD, ranging in age from 7 to 18 years, and 40 healthy age-matched and sex-matched individuals were included in this study. The patients and healthy controls filled in the Buss-Perry Aggression Questionnaire and Bryant's Empathy Index for Children and Adolescents; the Reading the Mind in the Eyes test was then completed. Blood samples were collected for OT at the beginning of the study. Lower serum OT levels were observed in patients with ADHD compared with the healthy controls. Moreover, there was a negative correlation between serum OT level and aggression scores and a positive correlation between the serum OT level and empathy scores in patients with ADHD. We conclude that OT may play a role in aggression and empathy skills, affecting the social life of those with ADHD.

The roles of CC2D1A and HTR1A gene expressions in autism spectrum disorders.

Classical autism belongs to a group of heterogeneous disorders known as autism spectrum disorders (ASD). Autism is defined as a neurodevelopmental disorder, characterized by repetitive stereotypic behaviors or restricted interests, social withdrawal, and communication deficits. Numerous susceptibility genes and chromosomal abnormalities have been reported in association with autism but the etiology of this disorder is unknown in many cases. CC2D1A gene has been linked to mental retardation (MR) in a family with a large deletion before. Intellectual disability (ID) is a common feature of autistic cases. Therefore we aimed to investigate the expressions of CC2D1A and HTR1A genes with the diagnosis of autism in Turkey. Forty-four autistic patients (35 boys, 9 girls) and 27 controls were enrolled and obtained whole blood samples to isolate RNA samples from each participant. CC2D1A and HTR1A gene expressions were assessed by quantitative Real-Time PCR (qRT-PCR) in Genome and Stem Cell Center, Erciyes University. Both expressions of CC2D1A and HTR1A genes studied on ASD cases and controls were significantly different (p < 0.001). The expression of HTR1A was undetectable in the ASD samples. Comparison of ID and CC2D1A gene expression was also found statistically significant (p = 0.028). CC2D1A gene expression may be used as a candidate gene for ASD cases with ID. Further studies are needed to investigate the potential roles of these CC2D1A and HTR1A genes in their related pathways in ASD.

The Activity of Adenosine Deaminase and Dipeptidyl Peptidase IV in Children With Attention Deficit Hyperactivity Disorder.

OBJECTIVE: In this study, to investigate the place of T cell-mediated immunity in the etiology of ADHD, for which we do not have enough information; we aimed to investigate the activity of DPP IV and ADA, which are T cell-related enzymes, and the relationship of these enzymes with ADHD symptoms in children with ADHD. METHODS: Twenty-seven children aged 6 to 12 years with a diagnosis of attention deficit hyperactivity disorder and 27 children aged 6 to 12 years without any psychiatric disease were included in the study. RESULTS: While serum ADA and DPP-IV activity were found to be statistically significantly higher in the group with ADHD. There was no statistically significant correlation between serum ADA and DPP-IV activities and CTRS-R-L and CPRS-R-L in both groups. CONCLUSION: We think that T cell mediated inflammation may play a role in the etiology of ADHD due to changes in ADA and DPP-IV levels in children.

Pupillary dilation response to the auditory food words in adolescents with obesity without binge eating disorder.

Childhood obesity is a growing global public health problem. Studies suggest that environmental cues contribute to developing and maintaining obesity. We aimed to evaluate pupillary changes to auditory food words vs. nonfood words and to conduct a dynamic temporal analysis of pupil size changes in adolescents with obesity without binge eating disorder by comparing healthy-weight adolescents. In this study, a total of 63 adolescents aged 12-18 years (n = 32, obesity group (OG); n = 31, control group (CG)) were included. In an auditory paradigm, participants were presented with a series of high and low-calorie food and nonfood words. A binocular remote eye-tracking device was used to measure pupil diameter. Generalized additive mixed models (GAMMs) were used for dynamic temporal analysis of pupillometry data. The results of GAMM analysis indicated that CG had larger pupil dilation than the OG while listening to auditory food words. CG had larger pupil dilation in food words than in nonfood words. However, the OG had a similar pupillary response in food and nonfood words. Pupil dilation response to higher-calorie foods was extended over the later stages of the time period (after 2000 ms) in the OG. In summary, our findings indicated that individuals with obesity had lower pupil dilation to auditory food words compared to normal-weight peers. Adolescents with obesity had prolonged pupillary dilation in higher calories of food words. The individual psychological factors affecting the dynamic changes of pupil responses to food cues in adolescents with obesity should be examined in further studies.

Interactions between autistics and healthy children and their parents in emotional availability: a comparative study.

In this study, we assessed the interactions of mothers and fathers with their children diagnosed with autism spectrum disorder (ASD) in terms of emotional availability (EA) and compared them with the interactions of healthy controls. Children, aged 13-60 months and applied to the Infant Mental Health Unit between January 2019 and March 2021 and their parents without any clinical diagnosis, were included. The EA levels of mothers and fathers of the autistic group, which included 30 boys and 13 girls, and those of the control group, which included 10 boys and 10 girls, were compared. According to the results obtained, it was determined that the EA levels of mothers and fathers of healthy controls were not different; however, the mothers were more sensitive and better in structuring the content of play compared with the fathers in the ASD group. It was noted that the fathers of children with ASD were more hostile than the mothers. EA should be taken as a criterion to determine the intensity and content of treatment, particularly in ASD. Additionally, increased awareness of fathers in EA may provide better results in the intervention process.

Investigation of Liver X Receptor Gene Variants and Oxysterol Dysregulation in Autism Spectrum Disorder.

The NR1H2 gene produces the Liver X Receptor Beta (LXRB) protein, which is crucial for brain cholesterol metabolism and neuronal development. However, its involvement in autism spectrum disorder (ASD) remains largely unexplored, aside from animal studies. This study is the first to explore the potential link between autism and rs2695121/rs17373080 single nucleotide polymorphisms (SNPs) in the regulatory regions of NR1H2, known for their association with neuropsychiatric functions. Additionally, we assessed levels of oxysterols (24-Hydroxycholesterol, 25-Hydroxycholesterol, 27-Hydroxycholesterol), crucial ligands of LXR, and lipid profiles. Our cohort comprised 107 children with ASD and 103 healthy children aged 2-18 years. Clinical assessment tools included the Childhood Autism Rating Scale, Autistic Behavior Checklist, and Repetitive Behavior Scale-Revised. Genotyping for SNPs was conducted using PCR-RFLP. Lipid profiles were analyzed with Beckman Coulter kits, while oxysterol levels were determined through liquid chromatography-tandem mass spectrometry. Significantly higher total cholesterol (p = 0.003), LDL (p = 0.008), and triglyceride (p < 0.001) levels were observed in the ASD group. 27-Hydroxycholesterol levels were markedly lower in the ASD group (p ≤ 0.001). ROC analysis indicated the potential of 27-Hydroxycholesterol to discriminate ASD diagnosis. The SNP genotype and allele frequencies were similar in both groups (p > 0.05). Our findings suggest that disturbances in oxysterol metabolism, previously linked to neurodegeneration, may constitute a risk factor for ASD and contribute to its heterogeneous phenotype.

The validity and reliability of preschool age psychiatric assessment (PAPA) in Turkish population.

INTRODUCTION: The Preschool Age Psychiatric Assessment (PAPA) was developed in response to the need for a standard and reliable tool for assessing preschool-age psychiatric disorders. The aim of this study was to translate PAPA into the Turkish language and evaluate the validity and reliability. METHODS: The researchers translated the original PAPA to Turkish, and the Turkish version of PAPA was translated back into its original language by professional translators. After the psychiatric assessment of the 300 patients by child psychiatrist, the PAPA interview was implemented with the parents. The sociodemographic data form and the PAPA short forms were filled out by the clinician conducting the interview. The Child Behavior Checklist for Ages 1.5-5 (CBCL/1½-5) was completed by parents. RESULTS: The rate of detecting true positives and true negatives in all subscales when comparing PAPA with CBCL in children under 60 months ranged from 65% to 88%. The AUC values were above 50%, ranging from 0.56 to 0.72, indicating that PAPA performed reasonably well in detecting true positives and true negatives compared to CBCL. According to DC: 0-5, it was found that the adjustment was good for total psychopathologies, separation anxiety disorder, social anxiety disorder, and depression (κ = 0.67-0.79), and excellent for GAD and PTSD (κ = 0.81-1.00) CONCLUSION: The validity and reliability obtained from this study are valuable in our country for the objective identification of preschool children showing problematic symptom levels and for distinguishing them from children showing typical characteristics.

A life-threatening presentation of child physical abuse: jejunal perforation.

Intra-abdominal injuries from impacts are the second most common cause of death in battered children. However, it may be difficult to distinguish between accidental abdominal injury and abuse, especially in the absence of other clinical findings. Published reports are also limited about the diagnosis of abuse in children with intra-abdominal injury. We report a case with jejunal perforation, multiple soft tissue injuries, and occipital fracture secondary to child abuse who was initially admitted to our hospital with complaint of fever, cough, and vomiting. An exploratory laparotomy revealed perforation of the jejunum, and an end-to-end anastomosis was performed. The patient was evaluated by the hospital's child protective team to implement appropriate diagnostic and child-protective interventions, and the child was discharged home in 10 days.

Parent-child interaction, parental attachment styles and parental alexithymia levels of children with ASD.

AIM: Given the recent findings regarding the increased evidence for the presence of the alexithymia in parents of children with autism spectrum disorder (ASD), the construct of alexithymia in parents of children with ASD and its effect on adult romantic attachment style of parents, family functioning and parent-child relationship were investigated. METHODS: The sample included children diagnosed as having ASD, developmental delay (DD), and 27 typically developing children aged 1-5 years and their parents. The Crowell procedure, an observational and structured assessment was performed, and the quality of the parent-child relationship was assessed using the Parent-Infant Relationship-Global Assessment Scale (PIR-GAS) based on DC: 0-5. The Toronto Alexithymia Scale-20, Experiences in Close Relationships Revised, and the Family Assessment Device were administered to the parents. RESULTS: PIR-GAS scores were lower in the ASD group compared with the scores of the other groups. Family functioning rated by fathers of children with DD was lower than in the other groups. However, there was no significant difference between the groups in terms of alexithymia levels, and parent's own attachment styles in romantic relationships. CONCLUSIONS: ASD was found to be an independent predictor for disordered relationship between children and their parents. Appropriate family interventions focusing on enhancing social interaction and emotional development may be beneficial in the treatment of ASD.

Ubiquinone Levels as a Marker of Antioxidant System in Children with Attention Deficit Hyperactivity Disorder.

The aims of this study are to compare serum ubiquinone levels in children with attention deficit hyperactivity disorder (ADHD) with healthy controls and to investigate the correlation between ubiquinone levels of children with ADHD and their ADHD symptoms. Twenty-seven children who are 6-12 years old age with attention deficit hyperactivity disorder having clinically normal intelligence and 23 children with clinically normal intelligence and no psychiatric disorder of similar age and sex who referred to Ankara University School of Medicine Department of Child and Adolescent Psychiatry were included in this study. All children were diagnosed by same researcher using the Semi-Structured Clinical Interview for DSM-IV Scale for Affective Disorders and Schizophrenia Interview for School Children-Now and for the Life-Long Version (K-SADS-PL). Parents and teachers of the children completed the Conners Parent Rating Scale Revised Long Form (CPRS-LF) and Conners Teacher Rating Scale Revised Long Form (CTRS-LF). There were no statistically significant differences regarding the age, gender, and sociodemographic data of the groups. Serum ubiquinone levels of the ADHD group were significantly lower than the control group. We did not find any correlation between ubiquinone levels and clinical values. Since ubiquinone levels are lower in children with ADHD compared with controls, we suggest that decreased antioxidant levels may play a role in ADHD pathogenesis by disrupting oxidative balance.

BDNF gene expression association with suicide and psychiatric disorders in children and adolescents: (Relationship between BDNF gene expression and suicide).

OBJECTIVE: In the current study, it was aimed to investigate the relationship between BDNF gene expression and childhood suicide attempt, childhood traumatic experiences, and problem-solving skills in children and adolescents. METHODS: The suicide group consisted of 100 children and adolescents aged 11-18 years who were referred to our outpatient department due to suicide attempt. For further comparisons, 100 children and adolescents who have no any psychiatric diagnosis were referred to our same outpatient department were selected. A sociodemographic data form, the Schedule for Affective Disorders and Schizophrenia for School-Age Children- Present and Lifetime version (K-SADS-PL), the Suicide Intent Scale (SIS), Problem Solving Inventory (PSI), and the Childhood Trauma Questionnaire (CTQ) were used for both groups. Total RNA was isolated from whole blood samples and BDNF gene expression levels were measured using quantitative real time-polymerase chain reaction (QRT-PCR). RESULTS: The total and subscale scores of the PSI and CTQ were found to be significantly higher in the suicide group than in the control group. There was no significant difference between the groups in terms of BDNF gene expression levels. However, gene expression of BDNF was found significantly increased in patients who have any psychiatric disorder compared with the others. CONCLUSION: Our results indicate that BDNF gene expression could be more associated with psychiatric disorders rather than suicide attempt in children and adolescents.

A heritable profile of six miRNAs in autistic patients and mouse models.

Autism spectrum disorder (ASD) is a group of developmental pathologies that impair social communication and cause repetitive behaviors. The suggested roles of noncoding RNAs in pathology led us to perform a comparative analysis of the microRNAs expressed in the serum of human ASD patients. The analysis of a cohort of 45 children with ASD revealed that six microRNAs (miR-19a-3p, miR-361-5p, miR-3613-3p, miR-150-5p, miR-126-3p, and miR-499a-5p) were expressed at low to very low levels compared to those in healthy controls. A similar but less pronounced decrease was registered in the clinically unaffected parents of the sick children and in their siblings but never in any genetically unrelated control. Results consistent with these observations were obtained in the blood, hypothalamus and sperm of two of the established mouse models of ASD: valproic acid-treated animals and Cc2d1a+/- heterozygotes. In both instances, the same characteristic miRNA profile was evidenced in the affected individuals and inherited together with disease symptoms in the progeny of crosses with healthy animals. The consistent association of these genetic regulatory changes with the disease provides a starting point for evaluating the changes in the activity of the target genes and, thus, the underlying mechanism(s). From the applied societal and medical perspectives, once properly confirmed in large cohorts, these observations provide tools for the very early identification of affected children and progenitors.
