Meta-Analysis Review
Research Review: Psychological and psychosocial interventions for children and adolescents with depression, anxiety, and post-traumatic stress disorder in low- and middle-income countries - a systematic review and meta-analysis.
BACKGROUND
The incidence of depression, anxiety, and post-traumatic stress disorder (PTSD) among children and adolescents residing in low- and middle-income countries (LMICs) poses a significant public health concern. However, there is variation in the evidence of effective psychological interventions. This meta-analysis aims to provide a complete overview of the current body of evidence in this rapidly evolving field.
METHODS
We conducted searches on PubMed, Embase.com, and EBSCO/APA PsycInfo databases up to June 23, 2022, identify randomized controlled trials (RCTs) investigating the effectiveness of psychological interventions in LMICs that targeted children and adolescents with elevated symptoms above a cut-off score for depression, anxiety, and PTSD, comparing a psychological or psychosocial intervention with other control conditions. We conducted random effects meta-analyses for depression, anxiety, and PTSD symptoms. Sensitivity analysis for outliers and high-risk studies, and analyses for the publication bias were carried out. Subgroup analyses investigated how the intervention type, intervention format, the facilitator, study design, and age group of the participant predicted effect sizes.
RESULTS
Thirty-one RCTs (6,123 participants) were included. We found a moderate effect of interventions on depression outcomes compared to the control conditions (g = 0.53; 95% CI: 0.06-0.99; NNT = 6.09) with a broad prediction interval (PI) (-1.8 to 2.86). We found a moderate to large effect for interventions on anxiety outcomes (g = 0.88; 95% CI: -0.03 to 1.79; NNT = 3.32) with a broad PI (-3.14 to 4.9). Additionally, a moderate effect was observed on PTSD outcomes (g = 0.54; 95% CI: 0.19-0.9; NNT = 5.86) with a broad PI (-0.64 to 1.72).
CONCLUSIONS
Psychological and psychosocial interventions aimed at addressing depression, anxiety, and PTSD among children and adolescents in LMICs have demonstrated promising results. However, future studies should consider the variation in evidence and incorporate long-term outcomes to better understand the effectiveness of these interventions.

Review
Appropriate screening tools are required to accurately detect complex post traumatic stress disorder (CPTSD). This systematic review aimed to assess and compare measurement tools. A literature search using key words 'complex post traumatic stress disorder', 'PTSD', and 'assessment' was undertaken on Embase and PsychINFO during February 2022 by two reviewers. Inclusion criteria included full text papers between 2002-2022 which evaluated CPTSD using assessment tools. Exclusion criteria included reviews, editorials, meta-analyses, or conference abstracts. Twenty-two papers met selection criteria. Thirteen studies used the International Trauma Questionnaire (ITQ). Two studies each evaluated CPTSD with the International Trauma Interview (ITI) or Symptoms of Trauma Scale (SOTS). The Developmental Trauma Inventory (DTI), Cameron Complex Trauma Interview (CCTI), Complex PTSD Item Set additional to the Clinician Administered PTSD Scale (COPISAC), Complex Trauma Questionnaire (ComplexTQ), and Scale 8 of the Minnesota Multiphasic Personality Inventory Scale (MMPI) were used by a single study each. The ITQ was the most thoroughly investigated, validated across different populations, and is a convenient questionnaire for screening within the clinical setting. Where self-report measures are inappropriate, the ITI, SOTS, and COPISAC are interview tools which detect CPTSD. However, they require further validation and should be used alongside clinical history and examination.

Review
We aimed to conduct the first systematic narrative review and quality appraisal of existing evidence on the psychological consequences of crime in older victims in the community and psychological interventions. We searched five databases to identify all peer-reviewed literature published in English on psychological impact and/or interventions for older crime victims and quality appraised these using the Mixed-Methods Appraisal Tool, following Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines (Prospero: CRD42019140137). Evidence from included studies were narratively synthesized, along with their strengths and limitations. We found 20 studies on psychological distress in older victims, four of which included interventions. From these, we identified 30 different impacts including symptoms of anxiety, depression, post-traumatic stress disorder, emotions including humiliation and self-blame, and behavioral changes. Only feasibility interventions have been published, although promising results were reported for cognitive-behavioral informed treatments for depression and anxiety. Studies were wide-ranging in aims, crimes included, and outcomes used. Recommendations for improving the evidence-base and to raise the profile of this neglected population have been provided.

Review
High rates of nonresponse to evidence-based treatment for posttraumatic stress disorder (PTSD) have fueled the search for improved intervention. Evidence suggests that improvements in dispositional mindfulness (i.e., tendency to attend to the present with nonjudgment and nonreactivity) may help reduce PTSD symptoms. While some research suggests that transdiagnostic mindfulness-based interventions particularly target avoidance symptoms, the association between dispositional mindfulness and avoidance has yet to be systematically examined. To address this gap, we examined peer-reviewed studies that reported quantitative associations between avoidance and dispositional mindfulness among trauma-exposed adults, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2009 guidelines. Sixteen studies were identified for final review from PsycINFO and PubMed databases. Results suggest that mindfulness has a weak relationship with effortful avoidance. This weak relationship may be obscured in studies where effortful avoidance is measured among other symptoms (e.g., anhedonia). Mindfulness appeared to have stronger associations with symptoms of hyperarousal and negative alterations in cognition and mood. An important clinical implication is that high effortful avoidance may manifest among patients who report strong mindfulness skills. It may be helpful for clinicians to carefully assess how mindfulness is being used to cope.

Review
There is a dearth of evidence indicating the effectiveness of psychological interventions targeting depression and/or posttraumatic stress disorder (PTSD) for Black women in the United States (US) exposed to intimate partner violence (IPV). We searched PubMed, MEDLINE, PsycINFO, EBSCOhost, Social Sciences, Social Sciences Full Text, Social Work Abstracts, and Cochrane databases between September 2021 and October 2022, for original studies of randomized control trials (RCTs) reporting depression and/or PTSD interventions delivered to US Black women with histories of IPV. Of the 1,276 articles, 46 were eligible and 8 RCTs were ultimately included in the review; interventions for depression (four interventions, = 1,518) and PTSD (four interventions, = 477). Among Depression and PTSD interventions (one intervention, = 208), Beck's Depression Inventory II indicated = 35.2, = 12.6 versus = 29.5, = 13.1, <.01, and Davidson Trauma Scale indicated = 79.4, = 31.5 versus = 72.1, = 33.5, <.01, at pre- and post-intervention respectively. Also, some interventions reported severity of depression = 13.9 ( = 5.4) versus = 7.9 ( = 5.7) < 0.01, and PTSD ( = 8.08 vs. = 14.13, (1,117) = 9.93, < .01) at pre- and post-intervention respectively. Publication bias was moderate and varied between 12 and 17 via the Downs and Black Checklist for Methodological Rigor for RCTs. Psychological interventions targeting depression and/or PTSD for Black women with histories of IPV reflect moderate improvement. Interventions that account for cultural nuances specific to Black women are fundamental for improving outcomes for survivors presenting with depression and/or PTSD.

Review
INTRODUCTION
Posttraumatic stress disorder (PTSD) is characterized by alterations in emotional and cognitive processing. The current neurobiological model of PTSD posits that amygdala and prefrontal cortex functioning impairment underpins symptoms, such as altered emotional and cognitive processing. Additionally, these structures are key components of emotional and attention regulation.
AIM
This review sought to evaluate studies comparing PTSD group to non-PTSD controls performance in affective attention tasks during neuroimaging.
RESULTS
PTSD group behavioral performance when responding to affective stimuli differed from controls only in stroop-based tasks. However, neuroimaging techniques were able to identify brain activation differences even when behavioral differences were not present. Amygdala hyperactivation in PTSD patients was confirmed in most cases, but cortical networks results were not as consistent. More than a general reduction in activity, PTSD group data points out to impaired recruitment of ventral cortical structures and increased reliance on dorsal cortical structures during task performance.
CONCLUSION
Stroop-based tasks seem to be better at identifying differences in behavioral performance of PTSD individuals. PTSD individuals seems to present an altered brain activation pattern in affective attention tasks when compared to controls, where PTSD individuals seem to present enhanced amygdala activation and rely more on dorsal anterior cingulate cortex and posterior insula activation during tasks. The PROSPERO ID for this study is CRD42022355471.

Review
AIM OF THE STUDY
First, to provide a synthesis and analysis of available scientific literature regarding the level of work stress and burnout among emergency physicians. Second, to identify the effect of the specific work situation-related factors.
METHODS
A systematic search was performed in NCBI PubMed and Embase. Comparative primary studies, both systematic review and cross-sectional, quantifying burnout in emergency physicians were included. Only studies published between 2011 and 2022 were retained. Synonym sets were compiled for the search key for 'burnout & stress', 'emergency', 'physician' and 'burnout & posttraumatic stress disorder'.
RESULTS
Thirty-five papers were retained for further research. Emergency physicians scored significantly higher for all dimensions of burnout compared to other healthcare professions. Significant correlations for burnout were found with work characteristic and organizational factors. Critical incidents and aggression were identified as the most important acute work characteristics and organizational factors impacting emergency physician's mental wellbeing including the development of posttraumatic stress disorder. Moreover, personal factors such as age, personality, and coping strategies also play an important role in the development of burnout as well as work-related trauma.
CONCLUSION
Available studies show that emergency physicians report higher scores of emotional exhaustion and depersonalization when compared to other healthcare professionals. Work characteristics contribute to this, but work-related traumatic incidents and aggression are important determinants. Personal characteristics such as age, personality type D, previous experiences and coping strategies seem to be determining factors likewise. Emergency physicians showed a high risk for developing burnout and work stress-related problems.

Review
Ketamine is an effective antidepressant, but there is substantial variability in patient response and the precise mechanism of action is unclear. Neuroimaging can provide predictive and mechanistic insights, but findings are limited by small sample sizes. This systematic review covers neuroimaging studies investigating baseline (pre-treatment) and longitudinal (post-treatment) biomarkers of responses to ketamine. All modalities were included. We performed searches of five electronic databases (from inception to April 26, 2022). 69 studies were included (with 1751 participants). There was substantial methodological heterogeneity and no well replicated biomarker. However, we found convergence across some significant results, particularly in longitudinal biomarkers. Response to ketamine was associated with post-treatment increases in gamma power in frontoparietal regions in electrophysiological studies, post-treatment increases in functional connectivity within the prefrontal cortex, and post-treatment increases in the functional activation of the striatum. Although a well replicated neuroimaging biomarker of ketamine response was not identified, there are biomarkers that warrant further investigation.

Meta-Analysis Review
Post-traumatic stress disorder (PTSD) is a debilitating condition which has been related to problems in emotional regulation, memory and cognitive control. Psychotherapy has a non-response rate of around 50% and understanding the neurobiological working mechanisms might help improve treatment. To integrate findings from multiple smaller studies, we performed the first meta-analysis of changes in brain activation with a specific focus on emotional processing after psychotherapy in PTSD patients. We performed a meta-analysis of brain activation changes after treatment during emotional processing for PTSD with seed-based d mapping using a pre-registered protocol (PROSPERO CRD42020211039). We analyzed twelve studies with 191 PTSD patients after screening 3700 studies. We performed systematic quality assessment both for the therapeutic interventions and neuroimaging methods. Analyses were done in the full sample and in a subset of studies that reported whole-brain results. We found decreased activation after psychotherapy in the left amygdala, (para)hippocampus, medial temporal lobe, inferior frontal gyrus, ventrolateral prefrontal cortex, right pallidum, anterior cingulate cortex, bilateral putamen, and insula. Decreased activation in the left amygdala and left ventrolateral PFC was also found in eight studies that reported whole-brain findings. Results did not survive correction for multiple comparisons. There is tentative support for decreased activation in the fear and cognitive control networks during emotional processing after psychotherapy for PTSD. Future studies would benefit from adopting a larger sample size, using designs that control for confounding variables, and investigating heterogeneity in symptom profiles and treatment response.

Review
Firefighters are repeatedly exposed to work-related potential traumatic events and have an increased risk of developing post-traumatic stress disorder (PTSD). However, the mechanisms implicated in this relationship are not clear. The aim of this study was to analyse the risk and protective factors related to the development of PTSD in firefighters. According to PRISMA, a systematic review of scientific literature was conducted in Web of Science, PsycINFO, Scopus, PubMed and the Cochrane Central Register of Controlled Trials. Quality in Prognosis Studies (QUIPS) was used as the methodological quality indicator of the selected articles (PROSPERO reference CRD42020213009). Prognostic studies involving active firefighters with presence of post-traumatic symptomatology, presenting original findings, and written in Spanish or English were included. A total of 1768 potentially eligible articles were identified. According to the inclusion criteria, 87 articles were selected to evaluate the full text. Finally, 19 articles were included, comprising 12,298 active firefighters. There is high heterogeneity in the variables evaluated in the different studies. Taking the data for which this review has found more evidence (moderate support), operational stress, job duration, burnout, expressive suppression and rumination could be risk factors of PTSD, and belongingness and dispositional mindfulness could be protective factors. Other variables with weak support (e.g. resilience) were analysed. This review analyses the available literature, highlighting its scarcity for future research on the subject. Due to repeated trauma exposure, it is important to continue investigations and bear these variables in mind for the prevention of PTSD in firefighters.
