INTRODUCTION
Migration is often accompanied by interpersonal, material and abstract losses and can be associated with migratory grief. The correlates of migratory grief have not yet been sufficiently addressed in research. This review aims to systematically investigate the relationship between migratory grief and psychopathology, to map the current state of research on this highly relevant topic and to derive relevant implications for the target group.
METHOD
A systematic literature search of electronic databases (PubMed/Medline, PsycINFO, Web of Science) was conducted up until January 2023. Primary empirical quantitative and qualitative studies with migrants were included that assessed the association between migratory grief and psychopathology, using a specific instrument for migratory grief (quantitative) or named migratory grief as relevant topic (qualitative). Studies that only captured aspects of migratory grief, were not written in English, or were descriptive/non-peer-reviewed publications, were excluded. A quality assessment of all studies included was performed using the Mixed Methods Appraisal Tool. The results were synthesized using a narrative synthesis approach.
RESULTS
All studies (quan. = 4; qual. = 1) were cross-sectional and used convenience samples. The studies had a mean number of 83 participants with a total of N = 487 participants included in the current review. All included studies reported a significant relationship between migratory grief and psychological distress.
DISCUSSION
Despite the quality of the included studies being limited, our results show that there is a link between migratory grief and depression among refugees and migrants. However, there are only few studies in this currently and certainly also in the future relevant field of research, which is why further studies on factors influencing migratory grief as well as associations with other disorders would be desirable.

Meta-Analysis Review
Decision-making capacity (DMC) among psychiatric inpatients is a pivotal clinical concern. A review by Okai et al. (2007) suggested that most psychiatric inpatients have DMC for treatment, and its assessment is reliable. Nevertheless, the high heterogeneity and mixed results from other studies mean there is considerable uncertainty around this topic. This study aimed to update Okai's research by conducting a systematic review with meta-analysis to address heterogeneity. We performed a systematic search across four databases, yielding 5351 results. We extracted data from 20 eligible studies on adult psychiatric inpatients, covering DMC assessments from 2006 to May 2022. A meta-analysis was conducted on 11 papers, and a quality assessment was performed. The study protocol was registered on PROSPERO (ID: CRD42022330074). The proportion of patients with DMC for treatment varied widely based on treatment setting, the specific decision and assessment methods. Reliable capacity assessment was feasible. The Mini-Mental State Examination (MMSE), Global Assessment of Function (GAF), and Brief Psychiatric Rating Scale (BPRS) predicted clinical judgments of capacity. Schizophrenia and bipolar mania were linked to the highest incapacity rates, while depression and anxiety symptoms were associated with better capacity and insight. Unemployment was the only sociodemographic factor correlated with incapacity. Assessing mental capacity is replicable, with most psychiatric inpatients able to make treatment decisions. However, this capacity varies with admission stage, formal status (involuntary or voluntary), and information provided. The severity of psychopathology is linked to mental capacity, though detailed psychopathological data are limited.

Review
INTRODUCTION
Orthorexia nervosa (ON), characterized by a pathological preoccupation with "extreme dietary purity," is increasingly observed as a mental health condition among young adults and the general population. However, its diagnosis is not formally recognized and has remained contentious.
OBJECTIVE
In this systematic review, we attempt to overview previous reviews on ON, focusing on the methodological and conceptual issues with ON. This would serve both as a summary and a way to highlight gaps in earlier research.
METHODS
This systematic review took reference from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines, and using combinations of the search terms ("orthorexia" OR "orthorexia nervosa" OR "ON") AND ("review" OR "systematic review" OR "meta-analysis"), a literature search was performed on EMBASE, Medline and PsycINFO databases from inception up to October 31, 2023. Articles were included if (1) they were written or translated into English and (2) contained information pertaining to the diagnostic stability or validity of ON, or instruments used to measure ON symptoms and behaviors. Only review articles with a systematic literature search approach were included.
RESULTS
A total of 22 reviews were qualitatively reviewed. Several studies have reported variable prevalence of ON and highlighted the lack of thoroughly evaluated measures of ON with clear psychometric properties, with no reliable estimates. ORTO-15 and its variations such as ORTO-11, ORTO-12 are popularly used, although their use is discouraged. Existing instruments lack specificity for pathology and several disagreements on the conceptualization and hence diagnostic criteria of ON exist.
DISCUSSION
Previous reviews have consistently highlighted the highly variable (and contradictory) prevalence rates with different instruments to measure ON, lack of stable factor structure and psychometrics across ON measures, paucity of data on ON in clinical samples, and a need for a modern re-conceptualization of ON. The diagnosis of ON is challenging as it likely spans a spectrum from "normal" to "abnormal," and "functional" to "dysfunctional." "Non-pathological" orthorexia is not related to psychopathological constructs in the same way that ON is.

Review
Impulsivity is related to a host of mental and behavioral problems. It is a complex construct with many different manifestations, most of which are heritable. The genetic compositions of these impulsivity manifestations, however, remain unclear. A number of genome-wide association studies (GWAS) and post-GWAS analyses have tried to address this issue. We conducted a systematic review of all GWAS and post-GWAS analyses of impulsivity published up to December 2023. Available data suggest that single nucleotide polymorphisms (SNPs) in more than a dozen of genes (e.g., CADM2, CTNNA2, GPM6B) are associated with different measures of impulsivity at genome-wide significant levels. Post-GWAS analyses further show that different measures of impulsivity are subject to different degrees of genetic influence, share few genetic variants, and have divergent genetic overlap with basic personality traits such as extroversion and neuroticism, cognitive ability, psychiatric disorders, substance use, and obesity. These findings shed light on controversies in the conceptualization and measurement of impulsivity, while providing new insights on the underlying mechanisms that yoke impulsivity to psychopathology.

Despite being widely assumed, the worsening impact of unpredictability on pain perception remains unclear because of conflicting empirical evidence, and a lack of systematic integration of past research findings. To fill this gap, we conducted a systematic review and meta-analysis focusing on the effect of unpredictability on pain perception. We also conducted meta-regression analyses to examine the moderating effect of several moderators associated with pain and unpredictability: stimulus duration, calibrated stimulus pain intensity, pain intensity expectation, controllability, anticipation delay, state and trait negative affectivity, sex/gender and age of the participants, type of unpredictability (intensity, onset, duration, location), and method of pain induction (thermal, electrical, mechanical pressure, mechanical distention). We included 73 experimental studies with adult volunteers manipulating the (un)predictability of painful stimuli and measuring perceived pain intensity and pain unpleasantness in predictable and unpredictable contexts. Because there are insufficient studies with patients, we focused on healthy volunteers. Our results did not reveal any effect of unpredictability on pain perception. However, several significant moderators were found, ie, targeted stimulus pain intensity, expected pain intensity, and state negative affectivity. Trait negative affectivity and uncontrollability showed no significant effect, presumably because of the low number of included studies. Thus, further investigation is necessary to clearly determine their role in unpredictable pain perception.

Borderline personality disorder (BPD) is a serious public health problem. Dialectical Behavior Therapy (DBT) is a program that has provided encouraging results for its treatment. However, scientific evidence about its efficacy is scarce. Therefore, we aimed to describe the scientific production on the components of the DBT program and its therapeutic efficacy in the treatment of people with BPD. A systematic review with relevant keywords was conducted based on studies available in Scopus, Web of Science, and PubMed until June 2023, including studies in English, research on therapeutic intervention, studies with a randomized controlled trial (RCT) design that included people with the diagnosis of BPD. We found 18 RCTs, most of which supported the effectiveness of DBT for BPD. There were a total of 1,755 participants in these studies, most of whom were women. These studies looked for treating self-injurious behaviors, suicidal thoughts or ideations, number of visits to emergency services, and frequency of hospital admissions. Most studies revealed that both short-term DBT and standard DBT improved suicidality in BPD patients with small or moderate effect sizes, lasting up to 24 months after the treatment period. Furthermore, these studies showed that DBT can significantly improve general psychopathology and depressive symptoms in patients with BPD. Improvement of compliance, impulsivity, mood instability, as well as reduction in hospitalization rate are other findings observed in the trials following DBT. Although DBT shows efficacy in the treatment of BPD, heterogeneity in the methodologies employed is highlighted. Therefore, it is necessary to design studies from a homogeneous theoretical and methodological framework.

Review
Childhood Emotional Maltreatment (CEM) is a significant but under-studied risk factor for impaired mental health, with adolescents being particularly susceptible. This systematic review and meta-analysis, prospectively registered in PROSPERO as CRD42022383005, aims to synthesize the findings of studies investigating the association between CEM and adolescent psychopathology, making it the first attempt to the best of our knowledge. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines, a comprehensive search (PubMed, Scopus, PsycINFO, Science Direct, Embase, and ProQuest) yielded 12,224 studies, from which 72 were included in the qualitative synthesis. The meta-analysis was conducted on 76 effect sizes (ranging from 0.01 to 0.57) extracted from 56 studies. The assessment of publication bias utilized funnel plots, Egger's regression test, and the trim and fill method, if required. Additionally, a predictor analysis investigated the influence of study-level variables on the CEM-psychopathology association. Results revealed a significant positive correlation between CEM and adolescent psychopathology (Pooled association: 0.24-0.41) Furthermore, assessment of publication bias indicated no significant bias. The predictor analysis suggested minimal influence of study-level variables. The study underscores the urgent need to address CEM as a crucial risk factor for adolescent psychopathology. The significant positive correlation between CEM and psychopathological outcomes highlights the detrimental effects of CEM on adolescents. Awareness, prevention efforts, and targeted interventions are essential to mitigate these effects. Further studies with culturally diverse and larger sample sizes are required, with emphasis on methodological rigor, given that most of the identified studies showed a high risk of bias.

Meta-Analysis
Systematic Review and Meta-analysis of Exercise Interventions for Psychotic Disorders: The Impact of Exercise Intensity, Mindfulness Components, and Other Moderators on Symptoms, Functioning, and Cardiometabolic Health.
BACKGROUND AND HYPOTHESIS
Exercise therapy has been shown to be an effective complementary treatment for patients with psychotic disorders. However, the specific impacts of different training modalities remain poorly understood. This article aims to quantitatively review the moderating influence of different exercise modalities, hypothesizing that higher exercise intensity as well as utilization of mindfulness-based exercise (MBE) components, will improve intervention outcomes.
STUDY DESIGN
PubMed, Web of Science, and PsycINFO were searched from 2010 to March 2022 for randomized controlled trials investigating exercise interventions in patients with psychotic disorders (preregistration: https://doi.org/10.17605/OSF.IO/J8QNS). Outcomes considered were positive/negative symptoms, Positive and Negative Syndrome Scale (PANSS) General Psychopathology/Total scores, depressive symptoms, psychosocial functioning, quality of life, cardiorespiratory fitness, and body mass index. Separate meta-analyses, including moderator analyses, were performed to evaluate the moderating influence of different training modalities.
STUDY RESULTS
Of 6653 studies, 40 (n = 2111 patients) were included in the meta-analysis. The effects of moderate-intensity exercise exceed low-intensity approaches for PANSS Total scores (P = .02) and depressive symptoms (P = .04). The presence of MBE components was associated with improvements in positive symptoms (P = .04) and PANSS General Psychopathology subscores (P = .04) but also with higher error and between-study heterogeneity. Our analysis also shows improved intervention effects on depression in younger patients (P = .012) and improved psychosocial functioning scores following more frequent sessions (P < .01).
CONCLUSIONS
A minimum of moderate intensity should be considered. More frequent training sessions per week also seem to be beneficial. While adding mindfulness elements is promising, it increases heterogeneity and requires caution in terms of generalization.

Review
Many instruments have been developed to examine and quantify symptoms of psychopathology. The main objective of this systematic review was to examine the instrument choice employed to measure mental ill-health in professionals working in the veterinary industry and reporting of psychometric testing of these instruments by researchers. 78 papers were reviewed. A total of 73 different instruments used to measure 19 symptoms of mental ill-health were identified. Quality assessment of included papers indicated 9 were low, 63 were moderate, and 6 were high quality. Reliability testing was conducted and reported in 36 papers and validity testing was reported in 23 papers. There is considerable heterogeneity in instrument choice measuring symptoms of mental ill-health in this population and inconsistency in conducting and reporting psychometric testing of instruments across studies. Adopting commonly employed instruments that yield high quality data in psychometric testing of instruments would be beneficial at advancing understanding in this field.

Meta-Analysis Review
People with schizophrenia die prematurely, yet regional differences are unclear. PRISMA 2020-compliant systematic review/random-effects meta-analysis of cohort studies assessing mortality relative risk (RR) versus any control group, and moderators, in people with ICD/DSM-defined schizophrenia, comparing countries and continents. We conducted subgroup, meta-regression analyses, and quality assessment. The primary outcome was all-cause mortality. Secondary outcomes were suicide-, /natural-cause- and other-cause-related mortality. We included 135 studies from Europe (n = 70), North-America (n = 29), Asia (n = 33), Oceania (n = 2), Africa (n = 1). In incident plus prevalent schizophrenia, differences across continents emerged for all-cause mortality (highest in Africa, RR=5.98, 95 %C.I.=4.09-8.74, k = 1, lowest in North-America, RR=2.14, 95 %C.I.=1.92-2.38, k = 16), suicide (highest in Oceania, RR=13.5, 95 %C.I.=10.08-18.07, k = 1, lowest in North-America, RR=4.4, 95 %C.I.=4.07-4.76, k = 6), but not for natural-cause mortality. Europe had the largest association between antipsychotics and lower all-cause mortality/suicide (Asia had the smallest or no significant association, respectively), without differences for natural-cause mortality. Higher country socio-demographic index significantly moderated larger suicide-related and smaller natural-cause-related mortality risk in incident schizophrenia, with reversed associations in prevalent schizophrenia. Antipsychotics had a larger/smaller protective association in incident/prevalent schizophrenia regarding all-cause mortality, and smaller protective association for suicide-related mortality in prevalent schizophrenia. Additional regional differences emerged in incident schizophrenia, across countries, and secondary outcomes. Significant regional differences emerged for all-cause, cause-specific and suicide-related mortality. Natural-cause death was homogeneously increased globally. Moderators differed across countries. Global initiatives are needed to improve physical health in people with schizophrenia, local studies to identify actionable moderators.
