Summary: Schizophrenia is a neurodevelopmental disorder influenced by genetic and environmental factors. Understanding the genetic liability contributing to schizophrenia could lead to improved therapy and new treatment methods. Research focuses on genetic variants, such as copy number variations (CNVs) or single-nucleotide variants (SNVs). Certain CNVs, such as those associated with 22q11.2 microdeletion syndrome or 1q21.1 microduplication/microdeletion syndrome, increase the risk of developing schizophrenia. This article provides a unifying framework linking these CNVs and associated genetic disorders to schizophrenia and its various neural and behavioral abnormalities.

Summary: Fetal cervical teratoma is a rare congenital tumor that affects the survival of the patients. This article reports a case of this disease, in which histology and genetic sequencing techniques were used to analyze the tumor and identified a copy number variation related to chromosome 14q24.1-q24.3. Ultrasound and MRI can be used as reliable diagnostic tools, and surgical intervention with placental support can improve the chances of newborn survival.

Summary: This study found that cognitive deficits in patients with schizophrenia are associated with genetic variations in the inflammatory response, particularly the functional polymorphisms of the IL10 gene. Recent-onset patients performed better in cognitive tests. These results suggest that the role of cytokines in schizophrenia should be further investigated from the perspective of pro-/anti-inflammatory imbalance.

Summary: By analyzing the genomic architecture of a family enriched for psychosis, rare variants in the MACF1 gene associated with the disorder were identified, along with rare copy-number variants affecting relevant genes. These findings suggest a potential role of rare variants in contributing to schizophrenia and schizoaffective disorder, shedding new light on the genetic mechanisms of these conditions.

Summary: Early-Onset Schizophrenia is a rare mental disorder occurring before the age of 18, often accompanied by other neurodevelopmental symptoms and comorbidities. Research indicates that genetic variants associated with this disorder may involve the Wnt, cadherin, and cholecystokinin receptor signaling pathways.

Summary: In this study, rare potentially damaging single nucleotide variations (pdSNV) were found to be more common than potentially damaging copy number variations (pdCNV) in ASD patients. The combined yield of potentially damaging variations was substantial at 27%, indicating the importance of high-throughput sequencing in routine clinical workup for ASD.

Summary: This study investigated Epileptic encephalopathies (EEs) using Whole Exome Sequencing (WES) and found that combining the detection of disease-causing SNVs/Indels and CNVs can increase the diagnostic rate. Genetic causes were successfully identified in 46.6% of infants, with the majority of disease-causing variants inherited in a de novo pattern.

Summary: Top-down studies have identified patterns of neuroimaging alterations with extreme polygenic architecture, indicating shared genomic variants and neuroimaging patterns across diagnostic categories. In contrast, bottom-up studies have shown equally large effect sizes of high-risk neuropsychiatric mutations for neuroimaging and behavioral traits, highlighting the surprising discordant effect sizes and the necessity to decompose the heterogeneity hindering case-control studies in idiopathic conditions.

Summary: This report presents the findings from a survey on the impact of COVID-19 on child and adolescent psychiatry services in Europe. While service delivery was significantly affected at the beginning of the pandemic, the second survey showed a minor impact on care delivery. However, there was a dramatic increase in the perceived impact on the mental health and psychopathology of children and adolescents. Suicidal crises, anxiety disorders, eating disorders, and major depressive episodes were particularly affected. There was a substantial increase in referrals or requests for assessments, and CAP department heads expressed concerns about the long-term consequences of the crisis.

It also describes a European multicenter study that aims to identify predictive factors of outcome after parent-child psychotherapy. The study will assess child symptoms, parental anxiety/depression, and parent-child relationship through pre-and post-therapy questionnaires, and use multivariate linear regression analysis to identify predictive factors among various variables.

Summary: Children and youth treated with antipsychotic drugs may experience adverse drug reactions and poor treatment response, which could be related to genetic variations in drug metabolism. The most frequent adverse reactions observed were weight gain and metabolic syndrome, followed by lack of therapeutic effect and neurological issues. Studies on the pharmacogenetic profiles associated with these drugs have yielded conflicting results, but some cases have shown significant clinical improvement through genotyping. Further research, especially on the key enzyme CYP1A2, is needed to improve the risk-benefit assessment of prescribing olanzapine, clozapine, and/or loxapine for children and youth.

Summary: This study examines the specificity of the care pathway for young trauma victims at the Nice Pediatric Psychotrauma Center (NPPC). Findings show a high rate of PTSD and comorbidities, mainly sleep disorders and mood and anxiety disorders, in children and adolescents impacted by the terrorist attack. The study highlights the importance of early interventions and long-term care to prevent chronic PTSD in adulthood.

Summary: This study aims to improve the understanding of the pathophysiology of traumatic reactivation caused by the court trial of the 2016 terrorist attack in Nice, France, by assessing sleep disturbances and somatic symptoms. It is a monocentric longitudinal study conducted at the Nice Pediatric Psychotrauma Center, aiming to include 100 adolescents aged 12 to 17 who were directly or indirectly exposed to the attack. Assessments were conducted monthly starting one month before the trial.
