Meta-Analysis
IMPORTANCE
A cancer diagnosis and treatment may result in highly traumatic periods with lasting psychological consequences for children, adolescent, and young adult patients with cancer (CYACs). Early identification and management may prevent long-term psychological morbidity and suicide.
OBJECTIVE
To analyze risk, severity, and risk factors for depression, anxiety, psychotic disorders, and suicide in CYACs and noncancer comparators.
DATA SOURCES
Literature search of PubMed, MEDLINE, Embase, PsycINFO, CINAHL, and PubMed Central from January 1, 2000, to November 18, 2022.
STUDY SELECTION
Full-length articles in peer-reviewed journals that measured and reported risk and/or severity of depression, anxiety, psychotic disorders, and suicide mortality in CYACs and a noncancer comparator group.
DATA EXTRACTION AND SYNTHESIS
Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines were followed with prospective PROSPERO registration.
MAIN OUTCOMES AND MEASURES
Risk ratios (RRs) were used for dichotomous outcomes, and standardized mean differences (SMDs) were used for continuous outcomes. SMDs were defined as follows: 0.2, small; 0.5, medium; and 0.8, large. Sources of heterogeneity and risk factors were investigated using sensitivity, subgroup, and meta-regression analyses.
RESULTS
From 7319 records, 52 studies were included. Meta-analyses revealed that CYACs were at increased lifetime risk of severe symptoms or a disorder of depression (RR, 1.57; 95% CI, 1.29-1.92), anxiety (RR, 1.29; 95% CI, 1.14-1.47), and psychotic disorders (RR, 1.56; 95% CI, 1.36-1.80) relative to both matched controls and their siblings. Overall suicide mortality was not significantly elevated (RR, 1.63; 95% CI, 0.78-3.40). The mean severity of depression was found to be elevated in CYACs receiving treatment (SMD, 0.44; 95% CI, 0.13-0.74) and long-term survivors (SMD, 0.18; 95% CI, 0.02-0.33). The mean severity of anxiety was found to be elevated only during treatment (SMD, 0.16; 95% CI, 0.03-0.20).
CONCLUSIONS AND RELEVANCE
Findings of this systematic review and meta-analysis suggest that CYACs may experience lasting psychological burden long into survivorship. Timely identification, preventive efforts, and psycho-oncological intervention for psychological comorbidity are recommended.

Review
STUDY QUESTION
What is the existing empirical literature on the psychosocial health and wellbeing of the parents and offspring born at an advanced parental age (APA), defined as 40 years onwards?
SUMMARY ANSWER
Although the studies show discrepancies in defining who is an APA parent and an imbalance in the empirical evidence for offspring, mothers, and fathers, there is a drive towards finding psychotic disorders and (neuro-)developmental disorders among the offspring; overall, the observed advantages and disadvantages are difficult to compare.
WHAT IS KNOWN ALREADY
In many societies, children are born to parents at advanced ages and there is rising attention in the literature towards the consequences of this trend.
STUDY DESIGN SIZE DURATION
The systematic search was conducted in six electronic databases (PubMed including Medline, Embase, Scopus, PsycInfo, CINAHL, and SocINDEX) and was limited to papers published between 2000 and 2021 and to English-language articles. Search terms used across all six electronic databases were: ('advanced parental age' OR 'advanced maternal age' OR 'advanced paternal age' OR 'advanced reproductive age' OR 'late parent*' OR 'late motherhood' OR 'late fatherhood') AND ('IVF' OR 'in vitro fertilization' OR 'in-vitro-fertilization' OR 'fertilization in vitro' OR 'ICSI' OR 'intracytoplasmic sperm injection' OR 'reproductive techn*' OR 'assisted reproductive technolog*' OR 'assisted reproduction' OR 'assisted conception' OR 'reproduction' OR 'conception' OR 'birth*' OR 'pregnan*') AND ('wellbeing' OR 'well-being' OR 'psycho-social' OR 'social' OR 'ethical' OR 'right to reproduce' OR 'justice' OR 'family functioning' OR 'parental competenc*' OR 'ageism' OR 'reproductive autonomy' OR 'outcome' OR 'risk*' OR 'benefit*').
PARTICIPANTS/MATERIALS SETTING METHODS
The included papers were empirical studies in English published between 2000 and 2021, where the study either examined the wellbeing and psychosocial health of parents and/or their children, or focused on parental competences of APA parents or on the functioning of families with APA parents. A quality assessment of the identified studies was performed with the QATSDD tool. Additionally, 20% of studies were double-checked at the data extraction and quality assessment stage to avoid bias. The variables sought were: the geographical location, the year of publication, the methodological approach, the definitions of APA used, what study group was at the centre of the research, what research topic was studied, and what advantages and disadvantages of APA were found.
MAIN RESULTS AND THE ROLE OF CHANCE
A total number of 5403 articles were identified, leading to 2543 articles being included for title and abstract screening after removal of duplicates. This resulted in 98 articles included for a full-text reading by four researchers. Ultimately, 69 studies were included in the final sample. The key results concerned four aspects relevant to the research goals. (i) The studies showed discrepancies in defining who is an APA parent. (ii) There was an imbalance in the empirical evidence produced for different participant groups (mothers, fathers, and offspring), with offspring being the most studied study subjects. (iii) The research topics studied underlined the increased risks of neuro-developmental and psychotic disorders among offspring. (iv) The observed advantages and disadvantages were varied and could not be compared, especially for the offspring of APA parents.
LIMITATIONS REASONS FOR CAUTION
Only English-language studies, published between 2000 and 2021, found in the above-mentioned databases were considered for this review.
WIDER IMPLICATIONS OF THE FINDINGS
More research is necessary to understand the risks and benefits of building a family at an APA for the offspring when they reach adulthood. Furthermore, studies that explore the perspective of older fathers and older parents from non-Western societies would be highly informative.

Review
BACKGROUND
Prader-Willi syndrome (PWS) is a rare and complex neurodevelopmental disorder resulting from absent paternal expression of maternally imprinted genes at chromosomal locus 15q11-13. This absence of expression occurs as a consequence of a deletion on the chromosome 15 of paternal origin (ca. 70%), a chromosome 15 maternal uniparental disomy (mUPD; ca. 25%), or an imprinting centre defect (IC; ca. 1-3%). At birth, individuals with PWS are severely hypotonic and fail to thrive. Hyperphagia and characteristic physical and neuropsychiatric phenotypes become apparent during childhood. The risk for the development of a co-morbid psychotic illness increases during the teenage years, specifically in those with PWS due to the presence of an mUPD. The primary aim of this literature review is to inform clinical practice. To achieve this, we have undertaken a systematic analysis of the clinical research literature on prevalence, presentation, course, characteristics, diagnosis and treatment of psychotic illness in people with PWS. The secondary aim is to identify clinical aspects of psychotic illness in PWS in need of further investigation.
METHODS AND FINDINGS
A systematic literature review on psychosis in PWS was conducted on the databases Web of Knowledge, PubMed and Scopus, using the terms "((Prader-Willi syndrome) OR (Prader Willi Syndrome)) AND ((psychosis) OR (psychotic illness))". All articles written in English and reporting original human research were reviewed. In all but three of the 16 cohort studies in which the genetic types were known, the authors reported higher rates of psychosis in people with PWS resulting from an mUPD, compared to those with the deletion subtype of PWS. When psychosis was present the presentation was psychosis similar regardless of genetic type and was usually characterised by an acute onset of hallucinations and delusions accompanied by confusion, anxiety and motor symptoms.
CONCLUSIONS
The onset of confusion, an affective cyclical pattern with the presence of abnormal mental beliefs and experiences, usually of rapid onset is suggestive of the development of psychotic illness. Phenomenologically, this psychosis in people with PWS is atypical in comparison to schizophrenia and bipolar disorder in the general population. The relationship to psychosis in the general population and the optimum treatments remain uncertain.

Adolescence represents a critical period for brain and behavioural health and characterised by the onset of mood, psychotic and anxiety disorders. In rodents, neurogenesis is very active during adolescence, when is particularly vulnerable to stress. Whether stress-related neurogenesis changes influence adolescence onset of psychiatric symptoms remains largely unknown. A systematic review was conducted on studies investigating changes in hippocampal neurogenesis and neuroplasticity, hippocampal-dependent cognitive functions, and behaviour, occurring after adolescence stress exposure in mice both acutely (at post-natal days 21-65) and in adulthood. A total of 37 studies were identified in the literature. Seven studies showed reduced hippocampal cell proliferation, and out of those two reported increased depressive-like behaviours, in adolescent rodents exposed to stress. Three studies reported a reduction in the number of new-born neurons, which however were not associated with changes in cognition or behaviour. Sixteen studies showed acutely reduced hippocampal neuroplasticity, including pre- and post-synaptic plasticity markers, dendritic spine length and density, and long-term potentiation after stress exposure. Cognitive impairments and depressive-like behaviours were reported by 11 of the 16 studies. Among studies who looked at adolescence stress exposure effects into adulthood, seven showed that the negative effects of stress observed during adolescence on either cell proliferation or hippocampal neuroplasticity, cognitive deficits and depressive-like behaviour, had variable impact in adulthood. Treating adolescent mice with antidepressants, glutamate receptor inhibitors, glucocorticoid antagonists, or healthy diet enriched in omega-3 fatty acids and vitamin A, prevented or reversed those detrimental changes. Future research should investigate the translational value of these preclinical findings. Developing novel tools for measuring hippocampal neurogenesis in live humans, would allow assessing neurogenic changes following stress exposure, investigating relationships with psychiatric symptom onset, and identifying effects of therapeutic interventions.

Review
Mental health problems among children and adolescents are a significant global public health concern, with a prevalence of approximately 10-20%. Psychotropic medications, including stimulants, antipsychotics, antidepressants, and mood stabilizers, have been proven effective in treating various psychiatric disorders among children and adolescents. Despite the common use of these medications, they have various side effects and complications. This systematic review aimed to assess the trends and prevalence of psychotropic medication use among children and adolescents from 2013 to 2023. A comprehensive literature search was conducted in PubMed, Web of Science, Ovid, Scopus, and Cochrane databases using relevant keywords. Two independent researchers screened the studies for inclusion and exclusion criteria. Data were extracted using a Microsoft Excel spreadsheet (Microsoft Corporation, Redmond, WA), including information on study characteristics, participant demographics, psychiatric disorders, and psychotropic medications. The risk of bias assessment was performed using the ROBINS-I (Risk of Bias in Non-randomized Studies of Interventions) tool for non-randomized studies of interventions (NRSI) and Risk of Bias 2 (ROB2) for the randomized clinical trial. Data synthesis was conducted through a qualitative interpretation of the findings. A total of 52 papers were identified through the search, with 37 remaining after duplicate removal. After applying the inclusion and exclusion criteria, nine articles were considered suitable for the systematic review. A total of 9,034,109 patients suffered from several psychiatric diseases, such as autism, major depressive disorder, Down syndrome, attention-deficit/hyperactivity disorder, adjustment disorder, anxiety, bipolar disorder, conduct disorder, depression, personality disorder, psychotic disorder, tic disorder, pervasive developmental disorder, and disruptive behavior disorder. Stimulants showed a consistent prevalence rate over the years. Antidepressants, including selective serotonin reuptake inhibitors, have demonstrated variations over the years, with a substantial increase in 2015, followed by a decrease in subsequent years. In addition, antipsychotics, including atypical antipsychotics, have varied over the years; however, their use increased in 2023. Anticonvulsants and anxiolytics were also utilized, albeit at lower prevalence rates. This systematic review provides an overview of the trends and prevalence of psychotropic medication use among children and adolescents from 2013 to 2023. The prevalence of antipsychotic prescribing has shown fluctuations among different countries over the years, with a decline in recent years but a slight increase in 2023. Further research is warranted to explore the factors influencing these trends and to assess the long-term effectiveness and safety of psychotropic medications in children and adolescents.

Review
OBJECTIVE
Interpersonal Psychotherapy (IPT) is an evidence-based therapy. There have been increasing demand and training opportunities of IPT in China. Reviewing current evidence on its use in Chinese patients can help us understand the applicability of IPT in China and identify knowledge gaps to encourage and better future research in this field.
METHOD
We did a comprehensive search of three major electronic databases: PubMed (English), Chinese National Knowledge Infrastructure (CNKI) and WanFang Data (Chinese). We examined overall study design, outcome measures, data analyses and other parameters. We only selected articles of Randomized Clinical Trials (RCT) for this review. All study findings were grouped and summarized per psychiatric diagnoses. The meta-analysis and forest plots were performed whereas studies could be combined.
RESULTS
After a full text review of 132 articles, 40 were selected for the final review. Comparing with control groups, evidences supported the efficacy of IPT in Chinese patients with Major Depressive Disorder (MDD), Postpartum depression, Generalized Anxiety Disorder (GAD), Social Anxiety Disorder, Post Stress Traumatic Disorder (PTSD), and Post-psychotic Depression. It was also beneficial to college students and Chinese first-time mothers. Meta-analysis using a random-effects model consistently yielded significant score differences between the IPT and control groups ( < 0.0001) on MDD.
CONCLUSION
This systematic review has identified the current best evidence for IPT efficacy in Chinese population. The findings support IPT as an effective treatment in Chinese with certain psychiatric conditions, consistent with those from many other studies throughout the world.

BACKGROUND
People who experience incarceration are characterised by poor health profiles. Clarification of the disease burden in the prison population can inform service and policy development. We aimed to synthesise and assess the evidence regarding the epidemiology of mental and physical health conditions among people in prisons worldwide.
METHODS
In this umbrella review, five bibliographic databases (Web of Science, PubMed, PsycINFO, Embase, and Global Health) were systematically searched from inception to identify meta-analyses published up to Oct 31, 2023, which examined the prevalence or incidence of mental and physical health conditions in general prison populations. We excluded meta-analyses that examined health conditions in selected or clinical prison populations. Prevalence data were extracted from published reports and study authors were contacted for additional information. Estimates were synthesised and stratified by sex, age, and country income level. The robustness of the findings was assessed in terms of heterogeneity, excess significance bias, small-study effects, and review quality. The study protocol was pre-registered with PROSPERO, CRD42023404827.
FINDINGS
Our search of the literature yielded 1909 records eligible for screening. 1736 articles were excluded and 173 full-text reports were examined for eligibility. 144 articles were then excluded due to not meeting inclusion criteria, which resulted in 29 meta-analyses eligible for inclusion. 12 of these were further excluded because they examined the same health condition. We included data from 17 meta-analyses published between 2002 and 2023. In adult men and women combined, the 6-month prevalence was 11·4% (95% CI 9·9-12·8) for major depression, 9·8% (6·8-13·2) for post-traumatic stress disorder, and 3·7% (3·2-4·1) for psychotic illness. On arrival to prison, 23·8% (95% CI 21·0-26·7) of people met diagnostic criteria for alcohol use disorder and 38·9% (31·5-46·2) for drug use disorder. Half of those with major depression or psychotic illness had a comorbid substance use disorder. Infectious diseases were also common; 17·7% (95% CI 15·0-20·7) of people were antibody-positive for hepatitis C virus, with lower estimates (ranging between 2·6% and 5·2%) found for hepatitis B virus, HIV, and tuberculosis. Meta-regression analyses indicated significant differences in prevalence by sex and country income level, albeit not consistent across health conditions. The burden of non-communicable chronic diseases was only examined in adults aged 50 years and older. Overall, the quality of the evidence was limited by high heterogeneity and small-study effects.
INTERPRETATION
People in prisons have a specific pattern of morbidity that represents an opportunity for public health to address. In particular, integrating prison health within the national public health system, adequately resourcing primary care and mental health services, and improving linkage with post-release health services could affect public health and safety. Population-based longitudinal studies are needed to clarify the extent to which incarceration affects health.

Meta-Analysis
OBJECTIVE
While genetic and cohort studies suggest immune and reduction/oxidation (redox) alterations occur in psychosis, less is known about potential alterations in children and adolescents.
METHODS
We conducted a systematic review to identify immune and redox biomarker studies in children and adolescents (mean age ≤ 18 years old) across the psychosis spectrum: from psychotic like experiences, which are common in children, to threshold psychotic disorders like schizophrenia. We conducted meta-analyses when at least three studies measured the same biomarker.
RESULTS
The systematic review includes 38 pediatric psychosis studies. The meta-analyses found that youth with threshold psychotic disorders had higher neutrophil/lymphocyte ratio (Hedge's g = 0.40, 95 % CI 0.17 - 0.64), tumor necrosis factor (Hedge's g = 0.38, 95 % CI 0.06 - 0.69), C-reactive protein (Hedge's g = 0.38, 95 % CI 0.05 - 0.70), interleukin-6 (Hedge's g = 0.35; 95 % CI 0.11 - 0.64), and total white blood cell count (Hedge's g = 0.29, 95 % CI 0.12 - 0.46) compared to youth without psychosis. Other immune and oxidative stress meta-analytic findings were very heterogeneous.
CONCLUSION
Results from several studies are consistent with the hypothesis that signals often classified as "proinflammatory" are elevated in threshold pediatric psychotic disorders. Data are less clear for immune markers in subthreshold psychosis and redox markers across the subthreshold and threshold psychosis spectrum. Immune and redox biomarker intervention studies are lacking, and research investigating interventions targeting the immune system in threshold pediatric psychosis is especially warranted.

Review
Attention deficit hyperactivity disorder (ADHD) is a fairly common psychiatric disorder among children. It has substantial consequences in terms of quality of life for those experiencing it and their families. In managing ADHD symptoms medication plays an essential role, including stimulants such as methylphenidate being a key component. Nevertheless, concerns have been raised about possible adverse reactions connected to these drugs. Thus, in this systematic review, an extensive analysis was conducted aiming at understanding any negative repercussions specifically from prolonged exposure to these medications among patients diagnosed with ADHD. The methodology entailed adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. While capturing relevant data through a meticulous search in various databases, filtered according to preset inclusion and exclusion criteria, 13 studies were considered for analysis. Conclusions indicate that the administration of stimulant medications can potentially translate into a small rise in blood pressure along with increased heart rate particularly when amphetamines are taken. However, no reports of notable serious cardiovascular events have emerged. In the domain of neuropsychiatry, it appears that long-term usage of methylphenidate generally bears no serious consequences, even though a hike in risk levels related to the occurrence of psychotic episodes was detected among those treated with amphetamines. Several gastrointestinal side effects including decreased appetite and stomach pain were reported, however, findings regarding ocular abnormalities or growth-related effects stood inconclusive. Therefore, based on this data the consensus is that stimulant medications do generate manageable and mild negative outcomes within the ADHD population. It is vital however to highlight the need for careful observation and further scientific inquiry to achieve a better grasp on both immediate as well as long-term implications involved.

INTRODUCTION
The endocannabinoid (eCB) system disruption has been suggested to underpin the development of psychosis, fueling the search for novel, better-tolerated antipsychotic agents that target the eCB system. Among these, palmitoylethanolamide (PEA), an N-acylethanolamine (AE) with neuroprotective, anti-inflammatory, and analgesic properties, has drawn attention for its antipsychotic potential.
METHODS
This Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020-compliant systematic review aimed at reappraising all clinical and preclinical studies investigating the biobehavioral role of PEA in psychosis.
RESULTS
Overall, 13 studies were eligible for data extraction (11 human, 2 animal). Observational studies investigating PEA tone in psychosis patients converged on the evidence for increased PEA plasma (6 human) and central nervous system (CNS; 1 human) levels, as a potential early compensatory response to illness and its severity, that seems to be lost in the longer-term (CNS; 1 human), opening to the possibility of exogenously supplementing it to sustain control of the disorder. Consistently, PEA oral supplementation reduced negative psychotic and manic symptoms among psychosis patients, with no serious adverse events (3 human). No PEA changes emerged in either preclinical psychosis model (2 animal) studied.
DISCUSSION
Evidence supports PEA signaling as a potential psychosis biomarker, also indicating a therapeutic role of its supplementation in the disorder.
