Genome-wide analysis of gene expression has been widely applied to study the endometrium, although to our knowledge no systematic reviews have been performed. Here, we identified 74 studies that described transcriptomes from whole (unprocessed) endometrium samples and found that these fitted into three broad investigative categories; endometrium across the menstrual cycle, endometrium in pathology, and endometrium during hormone treatment. Notably, key participant information such as menstrual cycle length and body mass index was often not reported. Fertility status was frequently not defined and fertility-related pathologies, such as recurrent implantation failure (RIF) and recurrent pregnancy loss, were variably defined, while hormone treatments differed between almost every study. A range of 1307-3637 reported differentially expressed genes (DEG) were compared in 4-7 studies in five sub-categories; (i) secretory vs proliferative stage endometrium, (ii) mid-secretory vs early secretory stage endometrium, (iii) mid-secretory endometrium from ovarian stimulation-treated participants vs controls, (iv) mid-secretory endometrium from RIF patients vs controls, and (v) mid-secretory eutopic endometrium from endometriosis patients vs controls. Only the first two sub-categories yielded consistently reported DEG between ≥3 studies, albeit in small numbers (<40), and these were enriched in developmental process and immune response annotations. This systematic review, though not PROSPERO registered, reveals that limited demographic detail, variable fertility definitions and differing hormone treatments in endometrial transcriptomic studies hinders their comparison, and that the large majority of reported DEG do not advance the identification of underlying biological mechanisms. Future studies should apply network biology approaches and experimental validation to establish causal gene expression signatures.

Meta-Analysis
Baseline Severity as a Moderator of the Waiting List-Controlled Association of Cognitive Behavioral Therapy With Symptom Change in Social Anxiety Disorder: A Systematic Review and Individual Patient Data Meta-analysis.
IMPORTANCE
Social anxiety disorder (SAD) can be adequately treated with cognitive behavioral therapy (CBT). However, there is a large gap in knowledge on factors associated with prognosis, and it is unclear whether symptom severity predicts response to CBT for SAD.
OBJECTIVE
To examine baseline SAD symptom severity as a moderator of the association between CBT and symptom change in patients with SAD.
DATA SOURCES
For this systematic review and individual patient data meta-analysis (IPDMA), PubMed, PsycInfo, Embase, and the Cochrane Library were searched from January 1, 1990, to January 13, 2023. Primary search topics were social anxiety disorder, cognitive behavior therapy, and randomized controlled trial.
STUDY SELECTION
Inclusion criteria were randomized clinical trials comparing CBT with being on a waiting list and using the Liebowitz Social Anxiety Scale (LSAS) in adults with a primary clinical diagnosis of SAD.
DATA EXTRACTION AND SYNTHESIS
Authors of included studies were approached to provide individual-level data. Data were extracted by pairs of authors following the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline, and risk of bias was assessed using the Cochrane tool. An IPDMA was conducted using a 2-stage approach for the association of CBT with change in LSAS scores from baseline to posttreatment and for the interaction effect of baseline LSAS score by condition using random-effects models.
MAIN OUTCOMES AND MEASURES
The main outcome was the baseline to posttreatment change in symptom severity measured by the LSAS.
RESULTS
A total of 12 studies including 1246 patients with SAD (mean [SD] age, 35.3 [10.9] years; 738 [59.2%] female) were included in the meta-analysis. A waiting list-controlled association between CBT and pretreatment to posttreatment LSAS change was found (b = -20.3; 95% CI, -24.9 to -15.6; P < .001; Cohen d = -0.95; 95% CI, -1.16 to -0.73). Baseline LSAS scores moderated the differences between CBT and waiting list with respect to pretreatment to posttreatment symptom reductions (b = -0.22; 95% CI, -0.39 to -0.06; P = .009), indicating that individuals with severe symptoms had larger waiting list-controlled symptom reductions after CBT (Cohen d = -1.13 [95% CI, -1.39 to -0.88] for patients with very severe SAD; Cohen d = -0.54 [95% CI, -0.80 to -0.29] for patients with mild SAD).
CONCLUSIONS AND RELEVANCE
In this systematic review and IPDMA, higher baseline SAD symptom severity was associated with greater (absolute but not relative) symptom reductions after CBT in patients with SAD. The findings contribute to personalized care by suggesting that clinicians can confidently offer CBT to individuals with severe SAD symptoms.

Review
In unresectable stage III non-small cell lung cancer (NSCLC), the standard of care for most fit patients is concurrent chemotherapy with normofractionated radiotherapy (NFRT), followed by durvalumab consolidation. Nevertheless, almost half of patients will present locoregional or metastatic intrathoracic relapse. Improving locoregional control thus remains an important objective. For this purpose, stereotactic body radiotherapy (SBRT) may be a relevant treatment modality. We performed a systematic review of the literature that evaluate the efficacy and safety of SBRT in this situation, either instead of or in addition to NFRT. Among 1788 unique reports, 18 met the inclusion criteria. They included 447 patients and were mainly prospective (n = 10, including 5 phase 2 trials). In none, maintenance durvalumab was administered. Most reported SBRT boost after NFRT (n = 8), or definitive tumor and nodal SBRT (n = 7). Median OS varied from 10 to 52 months, due to the heterogeneity of the included populations and according to treatment regimen. The rate of severe side effects was low, with <5 % grade 5 toxicity, and mainly observed when mediastinal SBRT was performed without dose constraints to the proximal bronchovascular tree. It was suggested that a biologically effective dose higher than 112.3 Gy may increase locoregional control. SBRT for selected stage III NSCLC bears potential to improve loco-regional tumor control, but at present, this should only be done in prospective clinical trials.

INTRODUCTION AND OBJECTIVE
Radiographic evaluation of the maturity of mandibular third molars is a common method used for age estimation of adolescents and young adults. The aim of this systematic review was to examine the scientific base for the relationship between a fully matured mandibular third molar based on Demirjian's method and chronological age, in order to assess whether an individual is above or below the age of 18 years.
METHODS
The literature search was conducted in six databases until February 2022 for studies reporting data evaluating the tooth maturity using Demirjian´s method (specifically stage H) within populations ranging from 8 to 30 years (chronological age). Two reviewers screened the titles and abstracts identified through the search strategy independently. All studies of potential relevance according to the inclusion criteria were obtained in full text, after which they were assessed for inclusion by two independent reviewers. Any disagreement was resolved by a discussion. Two reviewers independently evaluated the risk of bias using the assessment tool QUADAS-2 and extracted the data from the studies with low or moderate risk of bias. Logistic regression was used to estimate the relationship between chronological age and proportion of subjects with a fully matured mandibular third molar (Demirjian´s tooth stage H).
RESULTS
A total of 15 studies with low or moderate risk of bias were included in the review. The studies were conducted in 13 countries and the chronological age of the investigated participants ranged from 3 to 27 years and the number of participants ranged between 208 and 5,769. Ten of the studies presented the results as mean age per Demirjian´s tooth stage H, but only five studies showed the distribution of developmental stages according to validated age. The proportion of subjects with a mandibular tooth in Demirjian´s tooth stage H at 18 years ranged from 0% to 22% among males and 0 to 16% in females. Since the studies were too heterogenous to perform a meta-analysis or a meaningful narrative review, we decided to refrain from a GRADE assessment.
CONCLUSION
The identified literature does not provide scientific evidence for the relationship between Demirjian´s stage H of a mandibular third molar and chronologic age in order to assess if an individual is under or above the age of 18 years.

Meta-Analysis Review
BACKGROUND
Early-onset psychosis (EOP) refers to the development of a first episode of psychosis before 18 years of age. Individuals at clinical high risk for psychosis (CHR-P) include adolescents and young adults, although most evidence has focused on adults. Negative symptoms are important prognostic indicators in psychosis. However, research focusing on children and adolescents is limited.
AIMS
To provide meta-analytical evidence and a comprehensive review of the status and advances in the diagnosis, prognosis and treatment of negative symptoms in children and adolescents with EOP and at CHR-P.
METHOD
PRISMA/MOOSE-compliant systematic review (PROSPERO: CRD42022360925) from inception to 18 August 2022, in any language, to identify individual studies conducted in EOP/CHR-P children and adolescents (mean age <18 years) providing findings on negative symptoms. Findings were systematically appraised. Random-effects meta-analyses were performed on the prevalence of negative symptoms, carrying out sensitivity analyses, heterogeneity analyses, publication bias assessment and quality assessment using the Newcastle-Ottawa Scale.
RESULTS
Of 3289 articles, 133 were included ( = 6776 EOP, mean age 15.3 years (s.d. = 1.6), males = 56.1%; = 2138 CHR-P, mean age 16.1 years (s.d. = 1.0), males = 48.6%). There were negative symptoms in 60.8% (95% CI 46.4%-75.2%) of the children and adolescents with EOP and 79.6% (95% CI 66.3-92.9%) of those at CHR-P. Prevalence and severity of negative symptoms were associated with poor clinical, functional and intervention outcomes in both groups. Different interventions were piloted, with variable results requiring further replication.
CONCLUSIONS
Negative symptoms are common in children and adolescents at early stages of psychosis, particularly in those at CHR-P, and are associated with poor outcomes. Future intervention research is required so that evidence-based treatments will become available.

CONTEXT
Adolescence is a critical developmental stage in which increasing concerns about body image (BI) coincide with the consolidation of dietary habits (DHs). Multiple studies have sought robust associations between BI and DHs to prevent unhealthy behaviors.
OBJECTIVE
The aim of this systematic review was to examine the available literature on the association between BI perception (BIP) and/or satisfaction (BIS) and DHs in adolescents.
DATA SOURCES
A search was carried out of 5 electronic databases (PubMed, SciELO, Cochrane, Embase, and PsycInfo) using a combination of keywords (and synonyms) related to adolescence, BI, and diet.
DATA EXTRACTION
Data screening, extraction, and quality assessment were performed independently by 2 investigators using the PRISMA and AXIS guidelines.
DATA ANALYSIS
Of 2496 articles screened, 30 articles, published in English or Spanish, that evaluated the relationship between BI and DHs in adolescents aged between 10 years and 18 years, were included. A relationship between accurate BI perception in adolescents and healthy DHs was reported in 5 articles (16.2%). A relationship between overestimation of body weight in adolescents and healthy DHs was reported in 4 articles (13.3%). A relationship between underestimation of body weight and unhealthy DHs was reported in 8 articles (26.7%). In addition, 4 articles (13.3%) reported a relationship between BIS and healthy DHs. The desire to gain weight was associated with unhealthy DHs in 3 (10%) of the articles, while the desire to lose weight was related to healthy DHs in 3 (10%) of the articles and to unhealthy DHs in 3 (10%) other articles. There were also gender differences in the relationship between BIP or BIS and DHs.
CONCLUSION
Adolescents who underestimate their body weight tend to report less healthy DHs than body weight overestimators. Adolescents unsatisfied with their BI and with a drive for thinness frequently engage in DHs linked to losing weight.

Review
BACKGROUND AND AIMS
Mutations in FDXR gene, involved in mitochondrial pathway, cause a rare recessive neurological disorder with variable severity of phenotypes. The most common presentation includes optic and/or auditory neuropathy, variably associated to developmental delay or regression, global hypotonia, pyramidal, cerebellar signs, and seizures. The review of clinical findings in previously described cases from literature reveals also a significant incidence of sensorimotor peripheral polyneuropathy (22.72%) and ataxia (43.18%). To date, 44 patients with FDXR mutations have been reported. We describe here on two new patients, siblings, who presented with a quite different phenotype compared to previously described patients.
METHODS
Clinical, neurophysiological, and genetic features of two siblings and a systematic literature review focused on the clinical spectrum of the disease are described.
RESULTS
Both patients presented with an acute-sub-acute onset of peripheral neuropathy and only in later stages of the disease developed the typical features of FDXR-associated disease.
INTERPRETATION
The peculiar clinical presentation at onset and the evolution of the disease in our patients and in some cases revised from the literature shed lights on a new possible phenotype of FDXR-associated disease: a peripheral neuropathy which can mimic an acute inflammatory disease.

Review
BACKGROUND
The consequences for children born with birth defects and developmental disabilities encompassed by foetal alcohol spectrum disorder (FASD) are profound, affecting all areas of social, behavioural and cognitive functioning. Given the strong evidence for a core deficit in executive functioning, underpinned by impaired self-regulation skills, there has been a growing focus on the development of interventions that enhance or support the development of executive functions (EFs).
OBJECTIVES
The primary objective of this review is to synthesise the evidence for structured psychological interventions that explicitly aim to improve EF in children. The review also sought to ascertain if the effectiveness of interventions were influenced by characteristics of the intervention, participants or type of EF targeted by the intervention.
SEARCH METHODS
Sixteen databases, 18 grey literature search locations and 9 trial registries were systematically searched to locate eligible studies (up to December 2020). These searches were supplemented with reference harvesting, forward citation searching, hand searches of topic-relevant journals and contact with experts.
SELECTION CRITERIA
Studies were included in the review if they reported on an impact evaluation of a psychological intervention aiming to improve EF in children 3-16 years who either had confirmed prenatal alcohol exposure or a formal diagnosis falling under the umbrella term of FASDs. Eligible study designs included randomised controlled trials (RCTs) and quasi-experimental designs with either no treatment, wait list control or an alternative treatment as a comparison condition. Single-group pre-post designs were also included.
DATA COLLECTION AND ANALYSIS
Standard methodological procedures expected by the Campbell Collaboration were used at all stages of this review. Standardised mean differences (SMDs) were used to estimate intervention effects, which were combined with random effects meta-analysis (data permitting). Risk of bias was assessed using the Cochrane Risk of Bias Tool (RoB2) and Cochrane Risk of Bias in Non-Randomised Studies-Interventions tool (ROBINS-I).
MAIN RESULTS
The systematic search identified 3820 unique records. After title/abstract and full-text screening, 11 eligible studies (reported in 21 eligible documents) were deemed eligible, with a combined 253 participants. Of the 11 studies, 6 were RCTs, 1 was a quasi-experiment and 4 were single-group pre-post intervention designs. All studies were rated as having an overall high or serious risk of bias, with some variation across domains for RCTs. For RCT and quasi-experimental studies, the overall effect of EF interventions on direct and indirect measures of EF generally favoured the experimental condition, but was not statistically significant. There was no difference between intervention and comparison groups on direct measures of auditory attention ( = 3; SMD = 0.06, 95% confidence interval [CI] = -1.06, 1.18), visual attention ( = 2; SMD = 0.90, 95% CI = -1.41, 3.21), cognitive flexibility ( = 2; SMD = 0.23, 95% CI = -0.40, 0.86), attentional inhibition ( = 2; SMD = 0.04, 95% CI = -0.58, 0.65), response inhibition ( = 3; SMD = 0.47, 95% CI = -0.04, 0.99), or verbal working memory ( = 1; = 0.6827; 95% CI = -0.0196, 1.385). Significant heterogeneity was found across studies on measures of auditory attention and visual attention, but not for measures of cognitive flexibility, attentional inhibition or response inhibition. Available data prohibited further exploration of heterogeneity. There was no statistical difference between intervention and comparison groups on indirect measures of global executive functioning ( = 2; SMD = 0.21, 95% CI = -0.40, 0.82), behavioural regulation ( = 2; SMD = 0.18, 95% CI = -0.43, 0.79), or emotional control ( = 3; SMD = 0.01, 95% CI = -0.33, 0.36). Effect sizes were positive and not significant for meta-cognition ( = 1; SMD = 0.23, 95% CI = -0.72, 1.19), shifting ( = 2; SMD = 0.04, 95% CI = -0.35, 0.43), initiation ( = 1; SMD = 0.04, 95% CI = -0.40, 0.49), monitoring ( = 1; SMD = 0.25, 95% CI = -0.20, 0.70) and organisation of materials ( = 1; SMD = 0.25, 95% CI = -0.19, 0.70). Effect sizes were negative and not statistically different for effortful control ( = 1; SMD = -0.53, 95% CI = -1.50, 0.45), inhibition ( = 2; SMD = -0.08, 95% CI = -0.47, 0.31), working memory ( = 1; SMD = 0.00, 95% CI = -0.45, 0.44), and planning and organisation ( = 1; SMD = -0.10, 95% CI = -0.55, 0.34). No statistically significant heterogeneity was found for any of the syntheses of indirect measures of EF. Based on pre-post single-group designs, there was evidence for small to medium sized improvements in EF based on direct measures (cognitive flexibility, verbal working memory and visual working memory) and indirect measures (behavioural regulation, shifting, inhibition and meta-cognition). However, these results must be interpreted with caution due to high risk of bias.
AUTHORS' CONCLUSIONS
This review found limited and uncertain evidence for the effectiveness of interventions for improving executive functioning in children with FASD across 8 direct and 13 indirect measures of EF. The findings are limited by the small number of high-quality studies that could be synthesised by meta-analysis and the very small sample sizes for the included studies.

Meta-Analysis Review
INTRODUCTION
A failure of maxillary incisor eruption is commonly attributed to the presence of a supernumerary tooth. This systematic review aimed to assess the percentage of impacted maxillary incisors that successfully erupt after surgical removal of supernumerary teeth with or without other interventions.
METHODS
Systematic literature searches without restrictions were undertaken in 8 databases for studies reporting any intervention aimed at facilitating incisor eruption, including surgical removal of the supernumerary alone or in conjunction with additional interventions published up to September 2022. After duplicate study selection, data extraction, and risk of bias assessment according to the risk of bias in nonrandomized studies of interventions and Newcastle-Ottawa scale, random-effects meta-analyses of aggregate data were conducted.
RESULTS
Fifteen studies (14 retrospective and 1 prospective) were included with 1058 participants (68.9% male; mean age, 9.1 years). The pooled eruption prevalence for removal of the supernumerary tooth with space creation or removal of the supernumerary tooth with orthodontic traction was significantly higher at 82.4% (95% confidence interval [CI], 65.5-93.2) and 96.9% (95% CI, 83.8-99.9) respectively, compared with removal of an associated supernumerary only (57.6%; 95% CI, 47.8-67.0). The odds of successful eruption of an impacted maxillary incisor after removal of a supernumerary were more favorable if the obstruction was removed in the deciduous dentition (odds ratio [OR], 0.42; 95% CI, 0.20-0.90; P = 0.02); if the supernumeraries were conical (OR, 2.91; 95% CI, 1.98-4.28; P <0.001); if the incisor was in the correct position (OR, 2.19; 95% CI, 1.14-4.20; P = 0.02), at the level of the gingival third (OR 0.07; 95% CI, <0.01-0.97; P = 0.04) and had incomplete root formation (OR, 9.02; 95% CI, 2.04-39.78; P = 0.004). Delaying removal of the supernumerary tooth 12 months after the expected eruption time of the maxillary incisor (OR, 0.33; 95% CI, 0.10-1.03; P = 0.05) and waiting >6 months for spontaneous eruption after removal of the obstacle (OR, 0.13; 95% CI, 0.03-0.50; P = 0.003) was associated with worse odds for eruption.
CONCLUSIONS
Limited evidence indicated that the adjunctive use of orthodontic measures and removal of supernumerary teeth might be associated with greater odds of successfull impacted incisor eruption than removal of the supernumerary tooth alone. Certain characteristics related to supernumerary type and the position or developmental stage of the incisor may also influence successful eruption after removal of the supernumerary. However, these findings should be viewed with caution as our certainty is very low to low because of bias and heterogeneity. Further well-conducted and reported studies are required. The results of this systematic review have been used to inform and justify the iMAC Trial.

Review
Indigenous families tend to move house more often, especially families with young children. However, little is known about the impact of high mobility on children's well-being and development. The aim of this systematic review was to examine the relationship between residential mobility and children's health, developmental, and educational outcomes for Australian, Canadian, and New Zealand Indigenous children (0-12 years). Four databases were investigated with pre-determined inclusion and exclusion criteria. The search identified 243 articles after independent screening by two authors. Eight studies assessing four child health outcomes were included, six quantitative and two qualitative. Child health outcomes were classified into four broad categories-physical health, social and emotional behavior, learning and development, and developmental risk. The review identified limited evidence; possible links were identified between high mobility and emotional and behavioral difficulties for younger children. One study identified evidence of a linear relationship between the number of houses a child has lived in since birth and developmental risk. Further research is needed to fully understand the impact of high residential mobility for Indigenous children at different developmental stages. Prioritizing the involvement, collaboration, and empowerment of Indigenous communities and leadership is critical for future research.
