The Role of Dietary Patterns and Nutritional Supplements in the Management of Mental Disorders in Children and Adolescents: An Umbrella Review of Meta-Analyses: Le rôle des habitudes alimentaires et des suppléments nutritionnels dans la prise en charge des troubles mentaux chez les enfants et les adolescents : une méta-revue de méta-analyses.

OBJECTIVE: In recent years, the relationship between nutrition and mental health has gained considerable interest. We identified, synthesized, and appraised all meta--analyses of randomized controlled trials (RCTs) and observational studies reporting on the efficacy of dietary patterns and nutrient supplements in the prevention and treatment of mental disorders in children and adolescents. METHODS: Systematic research in MEDLINE, PsycINFO, Scopus, and Cochrane Database of Systematic Reviews was completed on 8 January 2024. RESULTS: Our research found 24 meta-analyses: 14 on RCTs, 8 on observational studies, and 2 combining both. Emerging evidence suggests that omega-3, in particular eicosapentaenoic acid, and Vitamin D may have adjunctive benefits in the treatment of attention deficit hyperactivity disorder (ADHD), while no evidence was found for autism spectrum disorder (ASD). Observational data also indicated that prenatal folic acid supplementation (>400 µg daily) was associated with a reduced risk of ASD in offspring. In terms of dietary habits, several meta-analyses of observational data revealed that healthy dietary patterns (rich in fruits, vegetables, and fibre, low in saturated fats) during the prenatal period, childhood, and adolescence were linked to a significantly reduced risk of internalizing disorders and externalizing disorders. Conversely, unhealthy dietary habits (high in sugars, saturated animal fats, and industrial foods, low in fruits, vegetables, and fibre) are associated with an elevated risk of these mental health issues. However, the number of available studies on dietary interventions for the treatment of depression, ASD, and ADHD was limited, and the results obtained were either nonsignificant or contradictory. CONCLUSION: Our findings emphasize the need to establish clear causal relationships between dietary habits and the risk of mental illness in children and adolescents. Moreover, further investigation of the benefits observed with some nutrient supplements (such as omega-3 and vitamin D for ADHD) through larger-scale RCTs is imperative to establish more robust conclusions.

We investigated the link between nutrition and mental health in children and adolescents through a meta-review of 24 relevant meta-analyses. Emerging evidence suggests potential benefits of Omega-3 and Vitamin D in treating ADHD, while no evidence supports their effectiveness in ASD. Observational data also indicate that prenatal folic acid supplementation may lower ASD risk. Healthy dietary patterns reduce the risk of internalizing and externalizing disorders, whereas unhealthy habits elevate the risk. Limited studies on dietary interventions for depression, ASD, and ADHD provide inconclusive results. In summary, our results emphasize the need to clearly understand the cause-and-effect relationships between dietary habits and mental health risks in young individuals. Larger-scale randomized controlled trials are essential for confirming the observed benefits of nutrient supplements such as omega-3 and vitamin D in treating ADHD and for forming more reliable conclusions.

The Mental Health of First Nations Children in Manitoba: A Population-Based Retrospective Cohort Study Using Linked Administrative Data: La santé mentale des enfants des Premières Nations au Manitoba : une étude de cohorte rétrospective dans la population, à l'aide de données administratives liées.

OBJECTIVE: First Nations children face a greater risk of experiencing mental disorders than other children from the general population because of family and societal factors, yet there is little research examining their mental health. This study compares diagnosed mental disorders and suicidal behaviours of First Nations children living on-reserve and off-reserve to all other children living in Manitoba. METHOD: The research team, which included First Nations and non-First Nations researchers, utilized population-based administrative data that linked de-identified individual-level records from the 2016 First Nations Research File to health and social information for children living in Manitoba. Adjusted rates and rate ratios of mental disorders and suicide behaviours were calculated using a generalized linear modelling approach to compare First Nations children (n = 40,574) and all other children (n = 197,109) and comparing First Nations children living on- and off-reserve. RESULTS: Compared with all other children, First Nations children had a higher prevalence of schizophrenia (adjusted rate ratio (aRR): 4.42, 95% confidence interval (CI), 3.36 to 5.82), attention-deficit hyperactivity disorder (ADHD; aRR: 1.21, 95% CI, 1.09 to 1.33), substance use disorders (aRR: 5.19; 95% CI, 4.25 to 6.33), hospitalizations for suicide attempts (aRR: 6.96; 95% CI, 4.36 to 11.13) and suicide deaths (aRR: 10.63; 95% CI, 7.08 to 15.95). The prevalence of ADHD and mood/anxiety disorders was significantly higher for First Nations children living off-reserve compared with on-reserve; in contrast, hospitalization rates for suicide attempts were twice as high on-reserve than off-reserve. When the comparison cohort was restricted to only other children in low-income areas, a higher prevalence of almost all disorders remained for First Nations children. CONCLUSION: Large disparities were found in mental health indicators between First Nations children and other children in Manitoba, demonstrating that considerable work is required to improve the mental well-being of First Nations children. Equitable access to culturally safe services is urgently needed and these services should be self-determined, planned, and implemented by First Nations people.

[The place and function of the gender of child psychiatric carers]. / Place et fonction du genre des soignants en pédopsychiatrie.

In a child psychiatry unit, where it is said that men are reassuring and women are mothering, the group experience of carers on the function of their gender in child care was explored. Gender is relevant to institutional care, but creates a divide. Representations focus on fear, sexuality, violence and fragility. Caregivers, ambivalent about neutralising gender, suffer from representations of what it does to children and to the institution.

[IPA exercise at extreme ages of life, differences or similarities?] / Exercice IPA aux âges extrêmes de la vie, différences ou similitudes ?

Advanced practice nursing is intended for children, adolescents, adults and the elderly. In the field of mental health, this population-based approach allows advanced practice nurses to apply all of their skills for individualized and adapted care. Whether these professionals work in child and adolescent psychiatry or in psychiatry for the elderly, their practices have many similarities.

[Pharmacoresistance to psychotropic drugs in children and adolescents: Pharmacogenetic anomalies of cytochrome P450 2D6]. / La pharmacorésistance aux psychotropes chez l'enfant et l'adolescent : recherche d'anomalies pharmacogénétiques du cytochrome P450 2D6.

OBJECTIVES: Some patients in child and adolescent psychiatry present resistance to psychotropic drugs, often resulting in polytherapy, an increased risk of adverse events, and more frequent and longer hospitalisation. Psychotropic drugs are mainly metabolised in the liver, in particular by the CYP2D6 subunit of cytochrome P450. Anomalies such as a duplication of the CYP2D6 gene related to an ultra-rapid metaboliser phenotype has been described to be linked to clinical efficacy. However, little research has been done in child and adolescent psychiatry. METHODS: A multi-centric cross-sectional study in the southeast of France explored the relation between pharmaco-resistance to psychotropic drugs and the prevalence of duplications or polymorphisms of CYP2D6 associated with an ultra-rapid phenotype in children and adolescents with severe mental health disease. RESULTS: Twenty-two patients have been included. The presence of an ultra-rapid phenotype concerns one patient in our study. A second patient presents a slow metaboliser phenotype. CONCLUSIONS: This study allows a clinical characterisation of the population of pediatric drug-resistant patients whose severity and the impact of their pathology are major and require long-term care associated with repeated hospitalisations, multiple drug prescriptions and numerous side effects. However, a link between drug resistance to psychotropic drugs and CYP2D6 UFM abnormalities could not be confirmed. An additional pharmacogenetic analysis by a panel of genes applied in the metabolism, transport and action of psychotropic drugs should be considered to answer questions about the resistance and independent effects of CYP2D6.

[Pervasive refusal syndrome in children]. / Le syndrome de refus global de l'enfant.

Pervasive refusal syndrome is a rare clinical disorder affecting children and teenagers. It is characterised by social withdrawal and opposition which significantly affects how patients function and their treatment. The twenty or so cases reported in literature help to specify the main diagnostic and therapeutic elements. Early recognition of pervasive refusal syndrome is essential in order to treat these young patients as effectively as possible.

ALL OUR SONS: THE DEVELOPMENTAL NEUROBIOLOGY AND NEUROENDOCRINOLOGY OF BOYS AT RISK.

Why are boys at risk? To address this question, I use the perspective of regulation theory to offer a model of the deeper psychoneurobiological mechanisms that underlie the vulnerability of the developing male. The central thesis of this work dictates that significant gender differences are seen between male and female social and emotional functions in the earliest stages of development, and that these result from not only differences in sex hormones and social experiences but also in rates of male and female brain maturation, specifically in the early developing right brain. I present interdisciplinary research which indicates that the stress-regulating circuits of the male brain mature more slowly than those of the female in the prenatal, perinatal, and postnatal critical periods, and that this differential structural maturation is reflected in normal gender differences in right-brain attachment functions. Due to this maturational delay, developing males also are more vulnerable over a longer period of time to stressors in the social environment (attachment trauma) and toxins in the physical environment (endocrine disruptors) that negatively impact right-brain development. In terms of differences in gender-related psychopathology, I describe the early developmental neuroendocrinological and neurobiological mechanisms that are involved in the increased vulnerability of males to autism, early onset schizophrenia, attention deficit hyperactivity disorder, and conduct disorders as well as the epigenetic mechanisms that can account for the recent widespread increase of these disorders in U.S. culture. I also offer a clinical formulation of early assessments of boys at risk, discuss the impact of early childcare on male psychopathogenesis, and end with a neurobiological model of optimal adult male socioemotional functions.

ANXIETY AND ATTACHMENT TO THE MOTHER IN PRESCHOOLERS RECEIVING PSYCHIATRIC CARE: THE FATHER-CHILD ACTIVATION RELATIONSHIP AS A PROTECTIVE FACTOR.

This 49-family study is the first to explore the father-child relationship in a clinical population of preschoolers (at a tertiary care child psychiatry clinic) and to examine its relation to child anxiety and attachment to the mother. A moderation model of the father-child activation relationship on the relation between attachment to the mother and child anxiety was tested and discussed. Analyses confirmed the expected independence between mother-child attachment and father-child activation as well as the association between mother-child attachment and anxiety. The highest levels of anxiety were found in insecure children, and more specifically, in insecure-ambivalent children and insecure disorganized-controlling children of the caregiving subtype. Hypotheses regarding the relation between anxiety and activation were only partially confirmed. Finally, the activation relationship with the father was shown to have a moderating effect on the relation between attachment to the mother and child anxiety; activation by the father may be considered either a protective or a risk factor. Results for this clinical population of young children are discussed in the light of attachment theory and activation relationship theory. The study's findings have the potential to contribute to the development of preventative, diagnostic, and intervention programs that take both parental figures into account.

Methylphenidate-risperidone combination in child psychiatry: A retrospective analysis of 44 cases.

INTRODUCTION: Psychotimulant-antipyschotic combinations are frequently used in child psychiatry, but have been rarely described in the literature. METHOD AND PATIENTS: We propose here a retrospective study of 44 children who received the combination methylphenidate (MPH)-risperidone (RIS). The sample is composed of children who received either MPH (n=28) or RIS (n=16) as primary treatment. A vast majority of the children had a comorbid attention deficit hyperactivity disorder (ADHD) diagnosis. RESULTS: For over 60% of patients, regardless of their initial monotherapy, bitherapy decreased the symptoms of ADHD and conduct disorder, sleep disorders and anxiety. Concerning the safety of the bitherapy, a compensation effect on weight gain and appetite was respectively observed in 70% and 50% of patients. Even though iatrogenic tachycardia can be encountered with both drugs, it has never been reported when they are associated and we have reported a total of 3 cases in our study. We have also observed a case of dyskinesia resolved with the discontinuation of the treatment. DISCUSSION/CONCLUSION: MPH-RIS bitherapy appears to be particularly effective in ADHD with conduct disorder symptoms. Although tolerance may limit its use, the benefit/risk ratio seems favourable for a number of children.

[Not Available]. / Le traitement pharmacologique de l'insomnie en pédopsychiatrie.

Sleep disturbances are frequent in children and adolescents with psychiatric disorders nevertheless there are few drugs available to treat them. Only certain antihistaminic H1 have the marketing authorization for treatment of childhood insomnia. Very few studies have been made in children about the hypnotics that are most widely used in adult patients: zopiclone, zolpidem and the hypnotic benzodiazepines. However, melatonin has recently become the most studied hypnotic drug in children since the marketing of a sustained-released form gave it the status of a drug and improved its pharmacokinetic properties. In child psychiatry, pharmacological treatment of insomnia should be considered in patients with attention deficit hyperactivity disorder in which sleep disturbances can be aggravated by psycho stimulant treatment, in autism spectrum disorders, and in the anxiety/depression.
