Review
Psychotic symptoms, including hallucinations, delusions, and disorganized thinking and behaviors, are the hallmarks of schizophrenia; but may also present in the context of other psychiatric and medical conditions. Many children and adolescents describe psychotic-like experiences, which can be associated with other types of psychopathology and past experiences (e.g., trauma, substance use, and suicidality). However, most youth reporting such experiences do not have, nor will ever develop, schizophrenia or another psychotic disorder. Accurate assessment is critical because these different presentations have different diagnostic and treatment implications. For this review, we focus primarily on the diagnosis and treatment of early onset schizophrenia. In addition, we review the development of community-based first-episode psychosis programming, and the importance of early intervention and coordinated care.

Review
BACKGROUND
Academic pressure is a potential contributor to adolescent mental health problems, but international evidence on this association has never been synthesised.
METHODS
We conducted the first systematic review of the association between academic pressure and adolescent depression, anxiety, self-harm, suicidality, suicide attempts and suicide. We searched MEDLINE, PsycINFO, ERIC and Web of Science (core collection) up to November 24, 2022, for studies of school-going children or adolescents, which measured academic pressure or timing within the school year as the exposure and depression, anxiety, self-harm, or suicidal ideation, attempts or suicide as outcomes. Risk of bias was assessed using the Mixed Methods Appraisal Tool. We used narrative synthesis to summarise the evidence. The review was prospectively registered with PROSPERO (CRD42021232702).
RESULTS
We included 52 studies. Most studies assessed mixed anxiety and depressive symptoms (n = 20) or depressive symptoms (n = 19). Forty-eight studies found evidence of a positive association between academic pressure or timing within the school year and at least one mental health outcome.
LIMITATIONS
Most studies were cross-sectional (n = 39), adjusted for a narrow range of confounders or had other limitations which limited the strength of causal inferences.
CONCLUSIONS
We found evidence that academic pressure is a potential candidate for public health interventions which could prevent adolescent mental health problems. Large population-based cohort studies are needed to investigate whether academic pressure is a causal risk factor that should be targeted in school- and policy-based interventions.

The association between non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol ratio (NHHR) and suicidal ideation in adults: a population-based study in the United States.
BACKGROUND
The ratio of non-high-density lipoprotein cholesterol (non-HDL-C) to high-density lipoprotein cholesterol (HDL-C) (NHHR) serves as a reliable lipid indicator associated with atherogenic characteristics. Studies have indicated a potential connection between suicidality and lipid metabolism. This research aims to investigate any possible association between the NHHR and the emergence of suicidal ideation within the confines of the study.
METHODS
This study examined the association between NHHR levels and suicidal ideation using data from the National Health and Nutrition Examination Survey (NHANES), conducted in the United States spanning 2005 and 2016. Calculation of the NHHR corresponds to the proportion of HDL-C to Non-HDL-C. The Patient Health Questionnaire-9's ninth question was implemented for assessing suicidal ideation. Using subgroup analysis, smooth curve fitting, and multivariate logistic regression analysis, the research was conducted.
RESULTS
Encompassing a cohort of 29,288 participants, the analysis identified that 3.82% of individuals reported suicidal ideation. After using multivariable logistic regression and thorough adjustments, elevated NHHR levels were significantly and positively associated with a heightened likelihood of suicidal ideation, according to the findings (odds ratio [OR] = 1.06; 95% confidence interval [CI]: 1.02-1.11; P = 0.0048). Despite extensive adjustment for various confounding factors, this relationship remained consistent. An inverted U-shaped curve was utilized to illustrate the link between NHHR and suicidal ideation among nonsmokers; the curve's inflection point was situated at 7.80. Subgroup analysis and interaction tests (all P for interaction > 0.05) demonstrated that there was no significant influence of the following variables on this positive relationship: age, sex, race, body mass index, education level, married status, hypertension, diabetes, and smoking status.
CONCLUSION
Significantly higher NHHR levels were associated with an elevated likelihood of suicidal ideation. Based on these results, it is probable that NHHR may serve as a predictive indicator of suicidal ideation, emphasizing its potential utility in risk assessment and preventive strategies.

Meta-Analysis Review
BACKGROUND
Despite a surge in research on self-injury in the last decade, a summary of research findings about the development of Non-Suicidal Self-Injury (NSSI) over time in community youth samples is not yet present in the scientific literature. This study aims to summarize the empirical literature on this topic, examining both the occurrence (Study 1) and frequency (Study 2) of NSSI over time, and for this reason, a Systematic Review and Bayesian Meta-Analysis were conducted.
METHODS
Following the PRISMA guidelines, the longitudinal studies included in the systematic review consisted of 41 papers (Study 1 = 16; Study 2 = 25). Only studies with available data were included in the meta-analysis (Study 1 = 12; Study 2 = 11).
RESULTS
First, the findings highlight limits related to methodological aspects, the design of the studies, and the availability of data. Meta-analytic results shows that across development, the frequency (i.e., not the occurrence) of NSSI increases for the group of younger adolescents, remains stable in the group of middle adolescents, and it decreases for older adolescents.
LIMITATIONS
This study highlights some limitations that can be summarized in three different macro categories: the first refers to methodological aspects (e.g., the lifetime prevalence of NSSI), the second to the design of the studies (e.g., not homogeneous cohort; short-term covered), and the third to the availability of data.
CONCLUSIONS
The current meta-analysis tries to shed light on the longitudinal research on NSSI behavior and how this behavior develops in terms of both occurrence and frequency, providing practical and methodological indications for future research.

Trichotillomania is characterized by chronic pulling out of one's hair. Given the negative sequelae of trichotillomania, we examined rates of suicidal ideation and suicide attempts. Of the 219 adults (mean age = 29.5 years; 88% female) recruited, 40 (18.3%) reported lifetime suicidal ideation, and 5 (2.3%) reported a lifetime suicide attempt. Those with histories of suicidal ideation were significantly more likely to have major depressive disorder. Our findings suggest that suicidal ideation and attempts are common in trichotillomania and support the idea that comorbid depression should be considered a risk factor for suicidality.

Meta-Analysis Review
Biomarkers that can differentiate between psychiatric disorders with and without suicidal behavior history from each other and from healthy volunteers may explain part of the pathogenesis of suicidal behavior. We conducted the hitherto largest meta-analysis comparing immune biomarkers between subjects with and without suicide attempt history or death by suicide. The study protocol was registered with PROSPERO, CRD42020212841. Standardized mean differences (SMD) were pooled with random-effects models. Heterogeneity between studies was assessed with the I-statistic and publication bias was evaluated by the Egger test and funnel plots. Data were based on 36 studies including 2679 persons with suicidal behaviors and 6839 comparison subjects, and four immune-related biomarkers (CRP, IL-6, TNF-α and IL-1β). Suicidal behavior was associated with higher CRP blood levels compared with: healthy controls (SMD [95%CI] = 1.42[0.85-1.98]); patients with depression alone (SMD [95%CI] = 1.23[0.20-2.26]); and patients with any psychiatric disorders (SMD [95%CI] = 0.39[0.22-0.55]). IL-6 blood level was higher in patients with suicidal behaviors compared with healthy controls (SMD [95%CI] = 1.13[0.45-1.82]) and when compared with psychiatric patients without suicidal behaviors (SMD [95%CI] = 0.22 [0.11-0.33]). Meta-regression and subgroup analyses revealed that increased CRP in suicidal behavior is primarily driven by recent suicidal behavior. These results implicate the immune system and inflammatory response in suicidal behavior independent of a relationship to major psychiatric disorders, and that these biological measures are predominantly state-dependent markers. Future studies are needed to determine the cause-and-effect relationship of these immune system biomarkers with suicidal behavior, and their potential predictive properties.

IMPORTANCE
The suicide mortality rate per 100 000 population (SMRP) consistently decreased before the COVID-19 pandemic outbreak in Japan and then unexpectedly increased during the pandemic. However, the underlying mechanisms remain poorly understood.
OBJECTIVE
To identify trends in and factors associated with suicidal mortality and motives among students in Japan from 2007 to 2022.
DESIGN, SETTING, AND PARTICIPANTS
In this cross-sectional study, data on SMRPs among Japanese middle-school, high-school, and university students were obtained from the government suicide database Suicide Statistics of the National Police Agency.
MAIN OUTCOMES AND MEASURES
Age-dependent and temporal fluctuations in annual SMRPs, disaggregated by suicidal motive (7 categories and 52 subcategories), sex, and school, were analyzed using linear mixed-effect and joinpoint regression models, respectively.
RESULTS
Total suicide numbers from 2007 to 2022 were as follows: 760 male middle-school students, 635 female middle-school students, 2376 male high-school students, 1566 female high-school students, 5179 male university students, and 1880 female university students. The mean (SD) student populations from 2007 to 2022 were as follows: 1 752 737 (81 334) male middle-school students, 1 675 572 (78 824) female middle-school students, 1 648 274 (67 520) male high-school students, 1 614 828 (60 032) female high-school students, 1 652 689 (32 724) male university students, and 1 229 142 (57 484) female university students. Among male students, the leading motives were school-related factors (underachievement and worrying about the future), followed by family-related and health-related motives. Among female students, school-related and family-related motives decreased, but health-related motives showed an age-dependent increase. The SMRPs of middle-school male students and female students were almost equal (mean [SD], 2.7 [1.0] vs 2.4 [1.4]), but the age-dependent increase in SMRPs among male students was pronounced (mean [SD], high-school vs university male students, 9.1 [2.4] vs 19.6 [3.0]; high-school vs university female students, 6.1 [2.4] vs 9.6 [1.8]). However, the incidence of suicide among high-school students associated with health-related motives was greater in female students. The majority of suicides associated with major impactable suicidal motives (school-related, health-related, and family-related motives) began increasing before the pandemic. Changes in SMRP associated with interpersonal relationships, such as conflict with classmates or parents, were not significant, but the rates increased greatly during the pandemic.
CONCLUSIONS AND RELEVANCE
School-related, health-related, and family-related problems were major motives, whereas the impacts of health-related and family-related motives increased and decreased with age, respectively. Notably, most SMRPs associated with major impactable motives (underachievement, conflict with a parent or classmate, and mental illnesses) had already begun increasing in the late 2010s, indicating that recent increasing SMRPs among school-aged individuals were associated with pandemic-related factors and other factors affecting this generation before the pandemic. It may be inappropriate to uniformly apply research findings based on school-aged individuals to school-based suicide prevention programs for students in middle school, high school, and university.

Suicide is a leading cause of death worldwide, and childhood trauma has been found to be an important risk factor. However, the mechanisms linking trauma to suicide risk remain unclear. The current registered report sought to (1) investigate whether childhood trauma and its subtypes were related to suicide risk in adulthood and (2) explore the potential mechanisms associating childhood trauma with suicide and well-being, especially executive functioning, impulsivity, and stress. A cross-sectional survey of 457 individuals who reported experiencing suicide ideation in the past 12 months. Childhood trauma and its subtypes were associated with an increased risk of reporting recent suicide thoughts, COVID-19-related suicide attempts, and recent suicide attempts. There were also significant indirect effects of childhood trauma on recent suicide ideation and well-being through executive functioning and impulsivity. These findings show that childhood trauma is associated with suicide risk in adulthood and suggest that poorer executive functioning and higher levels of impulsivity contribute to this increased risk. These results have implications for the development of future interventions to reduce suicide vulnerability.

Review
Suicide is a serious global public health problem, with a worrying recent increase in suicide rates in both adolescent and adult populations. However, it is essential to recognize that suicide is preventable. A myriad of factors contributes to an individual's vulnerability to suicide. These factors include various potential causes, from psychiatric disorders to genetic and epigenetic alterations. These changes can induce dysfunctions in crucial systems such as the serotonergic, cannabinoid, and hypothalamic-pituitary-adrenal axes. In addition, early life experiences of abuse can profoundly impact an individual's ability to cope with stress, ultimately leading to changes in the inflammatory system, which is a significant risk factor for suicidal behavior. Thus, it is clear that suicidal behavior may result from a confluence of multiple factors. This review examines the primary risk factors associated with suicidal behavior, including psychiatric disorders, early life adversities, and epigenetic modifications. Our goal is to elucidate the molecular changes at the genetic, epigenetic, and molecular levels in the brains of individuals who have taken their own lives and in the plasma and peripheral mononuclear cells of suicide attempters and how these changes may serve as predisposing factors for suicidal tendencies.

BACKGROUND
Amidst growing evidence of the intricate link between physical and mental health, this study aims to dissect the relationship between the waist-to-weight index (WWI) and suicidal ideation within a representative sample of the US population, proposing WWI as a novel metric for suicide risk assessment.
METHODS
The study engaged a sample of 9500 participants in a cross-sectional design. It employed multivariate logistic and linear regression analyses to probe the association between WWI and suicidal ideation. It further examined potential nonlinear dynamics using a weighted generalized additive model alongside stratified analyses to test the relationship's consistency across diverse demographic and health variables.
RESULTS
Our analysis revealed a significant positive correlation between increased WWI and heightened suicidal ideation, characterized by a nonlinear relationship that persisted in the adjusted model. Subgroup analysis sustained the association's uniformity across varied population segments.
CONCLUSIONS
The study elucidates WWI's effectiveness as a predictive tool for suicidal ideation, underscoring its relevance in mental health evaluations. By highlighting the predictive value of WWI, our findings advocate for the integration of body composition considerations into mental health risk assessments, thereby broadening the scope of suicide prevention strategies.
