Review
Adolescence is a developmental period marked by changes in cognition, emotion, and social relations. For example, sensitivity to social feedback increases as peer relationships become more important yet less stable, leaving adolescents vulnerable to experiences of peer victimization and rejection. Given that prefrontal brain regions responsible for regulatory abilities continue to mature during adolescence, the brain is especially susceptible to environmental influences. As such, exposure to adverse peer experiences may undermine emotion regulation development. Thus, the present review sought to elucidate the association between adverse peer experiences and emotion regulation in adolescence (i.e. age 12-17 years). Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review of the literature assessing adverse peer experiences (victimization and rejection) and emotion regulation (including neurobiological, behavioral, cognitive levels of analysis) was conducted (N = 27). Results demonstrate that adverse peer experiences are negatively associated with emotion regulation processes, behaviorally and neurally. Although variability in definitions and measurement of constructs make nuanced comparisons between studies difficult, the present systematic review organizes this body of literature and discusses how promising theoretical perspectives, including the cognitive control of emotion model and social information processing theory, may help to explain this association. Finally, recommendations for future work to expand our understanding of these processes, and for intervention and prevention efforts (e.g., school-based violence prevention and socio-emotional learning programs, parenting practices) that may serve to ameliorate outcomes for youths facing adverse peer experiences and emotion dysregulation, are discussed.

Review
Cigarette smoking is often initiated during adolescence and an earlier age of onset is associated with worse health outcomes later in life. Paradoxically, the transition towards adulthood also marks the potential for recovery, as the majority of adolescents are able to quit smoking when adulthood emerges. This systematic review aimed to evaluate the evidence from both human and animal studies for the differential impact of adolescent versus adult repeated and long-term tobacco and nicotine exposure on cognitive and brain outcomes. The limited human studies and more extensive yet heterogeneous animal studies, provide preliminary evidence of heightened fear learning, anxiety-related behaviour, reward processing, nicotinic acetylcholinergic receptors expression, dopamine expression and serotonin functioning after adolescent compared to adult exposure. Effects of nicotine or tobacco use on impulsivity were comparable across age groups. These findings provide novel insights into the mechanisms underlying adolescents' vulnerability to tobacco and nicotine. Future research is needed to translate animal to human findings, with a focus on directly linking a broader spectrum of brain and behavioural outcomes.

Review
Bullying and psychoactive substance abuse are prevalent phenomena among adolescents and identified as health problems that may jeopardise the development of all those involved. This systematic review of the literature aims to identify the extent to which involvement in bullying and psychoactive substance use during adolescence are associated, as well as check for differences regarding the social roles of bullying. From the search for empirical articles published between January 2009 and December 2014 in seven electronic databases, 585 records were identified. After the criteria for inclusion and exclusion were applied, the remaining 40 studies were analyzed based on the design, characteristics of the sample and results of the relationship between bullying and psychoactive substance use. Most studies are quantitative and cross-sectional, and they showed mixed samples of boys and girls in the school environment, which was the place where the phenomena are studied by preference. The association between the perpetration of bullying and psychoactive substance use for adolescents of both sexes is revealed. In relation to victimization by bullying, it was not possible to determine the direction and characterization of the relationship with psychoactive substance use.

Review
PURPOSE
Varicocele is one of the most common genital conditions referred to pediatric urologists. Most adolescents with varicocele are asymptomatic and their fertility future (and surgery benefit) is largely unknown. This review assesses varicocele evaluation, management and indications for repair, as well as types and success of varicocelectomy.
MATERIALS AND METHODS
A systematic literature review was performed on Embase™, PubMed® and Google Scholar™ for adolescent varicocele. Original research articles and relevant reviews were examined, and a synopsis of these data was generated for a comprehensive review of clinical adolescent varicocele management.
RESULTS
The prevalence of adolescent varicocele is similar to the adult population. While ultrasound is the most sensitive method for determining testicular volumes, orchidometer measurement may be adequate to gauge significant discordance. Significant hypotrophy of the affected testis with poor total testicular volume may indicate a testis at risk and warrant surgical repair. Similar findings have been noted with an associated high peak retrograde venous flow. Testicular hypotrophy often resolves following surgery but may also improve spontaneously if followed through adolescence. Continued scrotal pain despite adequate support or serial abnormal semen analysis in Tanner stage V boys is an indication for varicocelectomy. Artery and lymphatic sparing techniques (microscopic subinguinal or laparoscopic) are associated with the lowest risk of recurrence and complications.
CONCLUSIONS
Overtreatment and under treatment are medically and financially costly. Abnormal serial semen analysis with or without testicular hypotrophy is an indication for varicocele repair. If observation remains the treatment, followup with an adult urologist should be encouraged until paternity is achieved.

Stressors play a defining role in youth development and, in particular, in adolescent psychological and behavioral adaptation. However, the nature of stressors experienced during adolescence has not been reviewed or investigated comprehensively. To bridge this gap, this investigation conducted a systematic review of adolescent stressors reported in the literature (Study 1, N = 18 studies) and a content analysis of self-reported stressors (Study 2, N = 1,568 adolescents, Mean age = 15.5 years, 41.5% female adolescents). The results converged in the identification of negative stressors (i.e., health issues, parental conflicts, issues with parents, teachers, peers or friends, romantic issues, concerns about the future and school) and positive stressors (i.e., leisure time, finding oneself, school or other accomplishments, social acquisitions, receiving help, romance and friendship, birth and good time in the family), which are highly occurring and highly intense among adolescents. Overall, these findings can guide researchers and practitioners towards developing efficient stressors measures, integrative theories on adolescent stress and development, as well as effective interventions targeting specific stress processes in the domains of education, criminology and psychopathology.

Review
OBJECTIVE
In adolescents and young adults, depressive symptoms are highly prevalent and dynamic. For clinicians, it is difficult to determine whether a young person reporting depressive symptoms is at risk of developing ongoing mood difficulties or whether symptoms form part of a transient maturational process. Trajectory analyses of longitudinally assessed symptoms in large cohorts have the potential to untangle clinical heterogeneity by determining subgroups or classes of symptom course and their risk factors, by interrogating the impact of known or suspected risk factors on trajectory slope and intercept and by tracing the interrelation between depressive symptoms and other clinical outcomes over time.
METHOD
We conducted a systematic review of trajectory studies conducted in cohorts including people aged between 15 and 25 years.
RESULTS
We retrieved 47 relevant articles. These studies suggest that young people fall into common mood trajectory classes and that class membership and symptom course are mediated by biological and environmental risk factors. Furthermore, studies provide evidence that high and persistent depressive symptoms are associated with a range of concurrent health and behavioral outcomes.
CONCLUSION
Findings could assist in the formulation of novel concepts of depressive disorders in young people and inform preventive strategies and predictive models for clinical practice.

Meta-Analysis Review
BACKGROUND
Cyclic alternating pattern (CAP) is the electroencephalogram (EEG) pattern described as a marker of sleep instability and assessed by NREM transient episodes in sleep EEG. It has been associated with brain maturation. The aim of this review was to evaluate the normative data of CAP parameters according to the aging process in healthy subjects through a systematic review and meta-analysis.
METHODS
Two authors independently searched databases using PRISMA guidelines. Discrepancies were reconciled by a third reviewer. Subgroup analysis and tests for heterogeneity were conducted.
RESULTS
Of 286 studies, 10 submitted a total of 168 healthy individuals to CAP analysis. Scoring of CAP can begin at 3 months of life, when K-complexes, delta bursts, or spindles can be recognized. Rate of CAP increased with age, mainly during the first 2 years of life, then decreased in adolescence, and increased in the elderly. The A1 CAP subtype and CAP rate were high in school-aged children during slow-wave sleep (SWS). A1 CAP subtypes were significantly more numerous in adolescents compared with other groups, while the elderly showed the highest amounts of A2 and A3 CAP subtypes. Our meta-analysis registered the lowest CAP rate in infants younger than 2 years old and the highest in the elderly.
CONCLUSIONS
This review summarized the normative data of CAP in NREM sleep during the aging process. The CAP rate increased with age and sleep depth, especially during SWS. Parameters of CAP may reflect gender hormonal effects and neuroplasticity. More reports on CAP subtypes are needed for their reference values establishment.

Review
OBJECTIVE
Depression screening among children and adolescents is controversial. In 2009, the United States Preventive Services Task Force first recommended routine depression screening for adolescents, and this recommendation was reiterated in 2016. However, no randomized controlled trials (RCTs) of screening were identified in the original 2009 systematic review or in an updated review through February 2015. The objective of this systematic review was to provide a current evaluation to determine whether there is evidence from RCTs that depression screening in childhood and adolescence improves depression outcomes.
METHOD
Data sources included the MEDLINE, MEDLINE In-Process, EMBASE, PsycINFO, Cochrane CENTRAL and LILACS databases searched February 2, 2017. Eligible studies had to be RCTs that compared depression outcomes between children or adolescents aged 6 to 18 years who underwent depression screening and those who did not.
RESULTS
Of 552 unique title/abstracts, none received full-text review. No RCTs that investigated the effects of screening on depression outcomes in children or adolescents were identified.
CONCLUSIONS
There is no direct RCT evidence that supports depression screening among children and adolescents. Groups that consider recommending screening should carefully consider potential harms, as well as the use of scarce health resources, that would occur with the implementation of screening programs.

Meta-Analysis Review
There is a consistent link between perfectionism and eating disorders, however no meta-analysis to date has synthesized this literature in children and adolescents. We hypothesized that there would be significant, small pooled correlations between perfectionism dimensions and eating disorder symptoms in children and adolescents. Published, peer-reviewed articles with standardised measures of perfectionism and eating disorder symptoms were included. Articles were excluded if the age range was over 18 years. Overall, 39 studies were included (N = 13,954 participants, M age = 13.7 years). Total perfectionism (r = 0.25), perfectionistic strivings (r = 0.21), and perfectionistic concerns (r = 0.31) had significant positive associations with eating disorder symptoms. Most studies were rated as fair or good quality. Limitations included high heterogeneity, insufficient studies to investigate age as a moderator, the inclusion of only English articles, and predominately cross-sectional studies which precluded causal inference. Higher perfectionism was associated with greater eating disorder symptoms in children and adolescents. Future research should focus on longitudinal studies of eating disorder symptoms in children and adolescents.

Meta-Analysis Review
Sedentary behaviors are highly prevalent in youth and may be associated with markers of physical and mental health. This systematic review and meta-analysis aimed to quantify the age-related change in sedentary behavior during childhood and adolescence. Ten electronic databases were searched. Inclusion criteria specified longitudinal observational studies or control group from an intervention; participants aged ≥5 and ≤18 years; a quantitative estimate of the duration of SB; and English language, peer-reviewed publication. Meta-analyses summarized weighted mean differences (WMD) in device-assessed sedentary time and questionnaire-assessed screen-behaviors over 1-, 2-, 3-, or more than 4-year follow-up. Effect modification was explored using meta-regression. Eighty-five studies met inclusion criteria. Device-assessed sedentary time increased by (WMD 95% confidence interval [CI]) 27.9 (23.2, 32.7), 61.0 (50.7, 71.4), 63.7 (53.3, 74.0), and 140.7 (105.1, 176.4) min/day over 1-, 2-, 3-, and more than 4-year follow-up. We observed no effect modification by gender, baseline age, study location, attrition, or quality. Questionnaire-assessed time spent playing video games, computer use, and a composite measure of sedentary behavior increased over follow-up duration. Evidence is consistent in showing an age-related increase in various forms of sedentary behavior; evidence pertaining to variability across socio-demographic subgroups and contemporary sedentary behaviors are avenues for future research.
