Adolescent maturity and the brain: the promise and pitfalls of neuroscience research in adolescent health policy

Informed Consent in Decision-Making in Pediatric Practice

Informed consent should be seen as an essential part of health care practice; parental permission and childhood assent is an active process that engages patients, both adults and children, in their health care. Pediatric practice is unique in that developmental maturation allows, over time, for increasing inclusion of the child's and adolescent's opinion in medical decision-making in clinical practice and research. This technical report, which accompanies the policy statement "Informed Consent in Decision-Making in Pediatric Practice" was written to provide a broader background on the nature of informed consent, surrogate decision-making in pediatric practice, information on child and adolescent decision-making, and special issues in adolescent informed consent, assent, and refusal. It is anticipated that this information will help provide support for the recommendations included in the policy statement.

Power, Process, and Protection: Juveniles as Defendants in the Justice System

The juvenile court was created in 1899 in part to remedy the unfairness of trying youth in the adult criminal justice system, but its success at rectifying those problems is unclear. One concern is that the vast majority of youth who are adjudicated delinquent are adjudicated after waiving their right to trial and entering a guilty plea. Fairness and equity in the plea bargaining process are premised on the assumption that youth have the capacity to understand and elect between available options and will be given a meaningful opportunity to choose without coercion and deception. In legal terms, the Constitution will only sanction a plea when the defendant makes a knowing, voluntary, and intelligent waiver of her right to trial. In this chapter, we briefly describe the juvenile court process and explain the circumstances of a plea bargain, which constitutes both a waiver of Constitutional rights and an agreement to certain conditions. Then we evaluate the research and practice knowledge regarding the legal components of a valid waiver-that it must be knowing and voluntary. We consider how information, capacity, and circumstance contribute to a knowing waiver. Then we examine how procedural justice, paternalism, and coercion may affect a voluntary waiver. Throughout, we consider whether the people, policies, and practices meant to assess and safeguard that waiver decision fulfill their intended purpose.

Clustering of Risk Factors for Non-Communicable Diseases among Adolescents from Southern Brazil

INTRODUCTION

The aim of this study was to investigate the simultaneous presence of risk factors for non-communicable diseases and the association of these risk factors with demographic and economic factors among adolescents from southern Brazil.

METHODS

The study included 916 students (14-19 years old) enrolled in the 2014 school year at state schools in São José, Santa Catarina, Brazil. Risk factors related to lifestyle (i.e., physical inactivity, excessive alcohol consumption, smoking, sedentary behaviour and unhealthy diet), demographic variables (sex, age and skin colour) and economic variables (school shift and economic level) were assessed through a questionnaire. Simultaneous behaviours were assessed by the ratio between observed and expected prevalences of risk factors for non-communicable diseases. The clustering of risk factors was analysed by multinomial logistic regression. The clusters of risk factors that showed a higher prevalence were analysed by binary logistic regression.

RESULTS

The clustering of two, three, four, and five risk factors were found in 22.2%, 49.3%, 21.7% and 3.1% of adolescents, respectively. Subgroups that were more likely to have both behaviours of physical inactivity and unhealthy diet simultaneously were mostly composed of girls (OR = 3.03, 95% CI = 1.57-5.85) and those with lower socioeconomic status (OR = 1.83, 95% CI = 1.05-3.21); simultaneous physical inactivity, excessive alcohol consumption, sedentary behaviour and unhealthy diet were mainly observed among older adolescents (OR = 1.49, 95% CI = 1.05-2.12). Subgroups less likely to have both behaviours of sedentary behaviour and unhealthy diet were mostly composed of girls (OR = 0.58, 95% CI = 0.38-0.89); simultaneous physical inactivity, sedentary behaviour and unhealthy diet were mainly observed among older individuals (OR = 0.66, 95% CI = 0.49-0.87) and those of the night shift (OR = 0.59, 95% CI = 0.43-0.82).

CONCLUSION

Adolescents had a high prevalence of simultaneous risk factors for NCDs. Demographic (gender and age) and economic (school shift) variables were associated with the most prevalent simultaneous behaviours among adolescents.

Prenatal, perinatal, and adolescent exposure to marijuana: Relationships with aggressive behavior

This manuscript reviews research exploring the relationship between prenatal, perinatal, and adolescent exposure to marijuana and aggressive behavior, including physical aggression. Areas of inquiry include animal research, as well as human research, on prenatal exposure and on marijuana use during adolescence. Potential psychosocial and psychopharmacological mechanisms are identified, as well as relevant confounds. The prenatal marijuana exposure literature provides minimal support for a direct relationship with aggressive behavior in childhood. The adolescent use literature suggests a marginal (at best) association between acute intoxication and aggressive behavior, and an association between chronic use and aggressive behavior heavily influenced by demographic variables, rather than direct, psychopharmacological mechanisms. Cannabis withdrawal symptoms also may include aggression and anger, but there is little evidence to suggest that these effects are large or specific to withdrawal from marijuana compared to other substances. This review will offer recommendations for clinical care and public policy, as well as important questions for future research.

Associations Between Social Determinants of Health and Pregnancy Among Young People: A Systematic Review of Research Published During the Past 25 Years

OBJECTIVE

Major health disparities exist in pregnancy among young people. Although social determinant of health (SDH) approaches in interventions are promoted to reduce these disparities, little research exists that synthesizes empirical links between SDHs and pregnancy among young people. This systematic literature review utilized the Healthy People 2020 SDH framework to analyze and synthesize the empirical associations between SDHs and pregnancy among young people.

METHODS

We included studies that were published in the past 25 years from PubMed, PsycINFO®, and Academic Search" Premier databases. Twenty-two studies met all inclusion criteria and, following the Matrix Method, were assessed for methodological quality and empirical links between determinant areas and pregnancy.

RESULTS

Seventeen studies reported an empirical association between at least one SDH and pregnancy among young people. Areas most represented were poverty and family structure. No studies examined the relationship between pregnancies among young people and quality of housing, access to healthy foods, access to health-care services and primary care, health technology, social cohesion, perceptions of discrimination/equity, access to employment, employment status, school policies that support health promotion, safe school environments, or higher education enrollment.

CONCLUSION

This research indicates a need to expand the range of SDHs that are analyzed with pregnancy among young people and to focus interventions on areas that have been determined to have an empirical link with pregnancy.

Prefrontal Cortex Activation and Young Driver Behaviour: A fNIRS Study

Road traffic accidents consistently show a significant over-representation for young, novice and particularly male drivers. This research examines the prefrontal cortex activation of young drivers and the changes in activation associated with manipulations of mental workload and inhibitory control. It also considers the explanation that a lack of prefrontal cortex maturation is a contributing factor to the higher accident risk in this young driver population. The prefrontal cortex is associated with a number of factors including mental workload and inhibitory control, both of which are also related to road traffic accidents. This experiment used functional near infrared spectroscopy to measure prefrontal cortex activity during five simulated driving tasks: one following task and four overtaking tasks at varying traffic densities which aimed to dissociate workload and inhibitory control. Age, experience and gender were controlled for throughout the experiment. The results showed that younger drivers had reduced prefrontal cortex activity compared to older drivers. When both mental workload and inhibitory control increased prefrontal cortex activity also increased, however when inhibitory control alone increased there were no changes in activity. Along with an increase in activity during overtaking manoeuvres, these results suggest that prefrontal cortex activation is more indicative of workload in the current task. There were no differences in the number of overtakes completed by younger and older drivers but males overtook significantly more than females. We conclude that prefrontal cortex activity is associated with the mental workload required for overtaking. We additionally suggest that the reduced activation in younger drivers may be related to a lack of prefrontal maturation which could contribute to the increased crash risk seen in this population.

A systematic review of psychosocial interventions for children and young people with epilepsy

BACKGROUND

Despite recognition that psychosocial interventions can improve quality of life and mental health, there continues to be a lack of clarity and guidance around effective psychosocial interventions for children and young people with epilepsy. This review utilizes specific quality criteria to systematically identify and appraise the evidence for the effectiveness of psychosocial interventions for children and young people with epilepsy.

METHODS

A systematic search of six electronic databases was conducted using predefined eligibility criteria. The reference lists of previous review papers were also manually searched. Seventeen studies met the inclusion and exclusion criteria. A quality appraisal checklist, the 'Crowe Critical Appraisal Tool' (CCAT) (Crowe, 2013) [1] was applied to the included articles, and effect sizes were calculated when not provided in the papers.

RESULTS

Methodological quality of the majority of studies included was moderate, with only three studies rated as high quality. Meta-analysis was not conducted as the studies used heterogeneous methodologies and lacked consistency in outcome measures. Limited evidence was found for interventions improving epilepsy knowledge, quality of life, and psychological outcomes.

CONCLUSIONS

Psychosocial interventions may provide clinical benefit although further research is needed to clarify the most effective treatment components, delivery methods, and measurement of intervention outcomes. The existing evidence base for children and young people is limited by methodological issues such as the use of small samples, inadequate power, and a lack of controlled studies.

Relationships between risky sexual behaviour, dysexecutive problems, and mental health in the years following interdisciplinary TBI rehabilitation

Little is known about the long-term consequences of traumatic brain injury (TBI) regarding risky sexual behaviour. The objectives of the study were (1) to compare risky sexual behaviour in a sample of individuals with TBI having received interdisciplinary rehabilitation with that of healthy controls, and (2) to explore the relationships between risky sexual behaviour, executive functions, and mental health in individuals with TBI. The study group consisted of 42 individuals with TBI with a mean age of 37.9 years (SD = 9.7), 12.8 years of education (SD = 3.3), and 3.3 years post-injury (SD = 4.3). Healthy controls consisted of 47 participants, with a mean age of 37.6 years (SD = 10.7), and 13 years of education (SD = 3). Risky sexual behaviour was measured with the Sexual Risk Survey and executive function with the Dysexecutive Questionnaire. Mental health measures included the Generalised Anxiety Disorder Scale, and the Patient Health Questionnaire for depression. Compared to healthy controls, individuals with TBI reported more dysexecutive and mental health problems, without differences in risky sexual behaviour. In individuals with TBI, risky sexual behaviour was associated with behavioural, cognitive and emotional dysexecutive problems, but not with anxiety or depression. It was concluded that special attention should be given to individuals with TBI showing difficulties in executive functions given their association with risky sexual behaviour.

Transcranial Electrical Stimulation (tES) for the Treatment of Neuropsychiatric Disorders Across Lifespan

Abstract. Transcranial electrical stimulation (tES) is a safe, painless, and inexpensive noninvasive brain stimulation (NIBS) technique. tES has been shown to reduce symptoms in a variety of neuropsychiatric conditions such as depression, schizophrenia, anxiety, autism, and craving. There are many factors that can influence the effects of tES, such as current intensity, duration, baseline level of activity, gender, and age. Age is a critical variable, since the human brain undergoes several anatomic and functional changes across the lifespan. Therefore, tES-induced effects may not be the same across the lifespan. In this review we summarize the effects of tES, including tDCS, tACS, and tRNS, on clinical outcomes in several neuropsychiatric conditions, using a framework in which studies are organized according to the age of subjects. The use of tES in neuropsychiatric disorders has yielded promising results with mild, if any, adverse effects. Most of the published studies with tES have been conducted with tDCS in adult population. Future studies should focus on interventions guided by surrogate outcomes of neuroplasticity. A better understanding of neuroplasticity across the lifespan will help optimize current tES stimulation parameters, especially for use with children and elderly populations.

Drinking Over the Lifespan: Focus on College Ages

Many college students drink heavily and experience myriad associated negative consequences. This review suggests that a developmental perspective can facilitate a better understanding of college drinking. Specifically, using an emerging adulthood framework that considers the ongoing role of parents and neurodevelopmental processes can provide insight into why students drink. Most college students drink and tend to drink more and more heavily than their non-college-attending peers. These drinking patterns are affected by environmental and temporal characteristics specific to the college environment, including residential campus living, the academic week, and the academic year. Additional psychosocial factors are of particular relevance to the drinking behavior of college-age people, and include exaggerated peer norms, the development and use of protective behavioral strategies, and mental health considerations. Understanding the unique interaction of person and environment is key to designing prevention/intervention efforts.

Household Food Insecurity and Mental Health Problems Among Adolescents: What Do Parents Report?

OBJECTIVE

To investigate whether adolescents living in households with food insecurity have poorer parent-reported mental health (MH) than peers.

METHODS

We analyzed cross-sectional data from ∼8600 adolescents who participated in the 2007 (8th grade) wave of the Early Childhood Longitudinal Study-Kindergarten. Household food insecurity (HFI) was assessed by parental report on the 18-item US Household Food Security Scale. Total Difficulties score >13 on the parent-reported Strengths and Difficulties Questionnaire (SDQ) indicated problems with adolescent MH. SDQ subscale scores (Emotional, Conduct, Hyperactivity, Peer Problems) were also calculated. Associations between HFI and MH were explored in bivariate and multivariable analyses. Interactions of HFI and gender and HFI and receipt of free/reduced-price school lunch were analyzed with regard to problems with MH.

RESULTS

A total of 10.2% of adolescents lived with HFI; 11.2% had SDQ >13. Adolescents with HFI had higher rates of overall MH problems (28.7% vs 9.2%), emotional problems (21.6% vs 6.6%), conduct problems (26.5% vs 11.6%), hyperactivity (22.4% vs 11.3%), and peer problems (19.8% vs 8.6%) (all P < .01). After adjustment for confounders, the association between HFI and overall MH problems (odds ratio 2.3; 95% confidence interval 1.6-3.3) remained. Interactions of HFI and gender and HFI and free/reduced-price school lunch were not significant.

CONCLUSIONS

HFI was associated with increased risk of parent-reported MH problems among both male and female adolescents. Free/reduced-price school lunch did not significantly alter this relationship. Effective interventions to promote MH and reduce HFI among adolescents are necessary.

Evidence for a Role of Adolescent Endocannabinoid Signaling in Regulating HPA Axis Stress Responsivity and Emotional Behavior Development

Adolescence is a period characterized by many distinct physical, behavioral, and neural changes during the transition from child- to adulthood. In particular, adolescent neural changes often confer greater plasticity and flexibility, yet with this comes the potential for heightened vulnerability to external perturbations such as stress exposure or recreational drug use. There is substantial evidence to suggest that factors such as adolescent stress exposure have longer lasting and sometimes more deleterious effects on an organism than stress exposure during adulthood. Moreover, the adolescent neuroendocrine response to stress exposure is different from that of adults, suggesting that further maturation of the adolescent hypothalamic-pituitary-adrenal (HPA) axis is required. The endocannabinoid (eCB) system is a potential candidate underlying these age-dependent differences given that it is an important regulator of the adult HPA axis and neuronal development. Therefore, this review will focus on (1) the functionality of the adolescent HPA axis, (2) eCB regulation of the adult HPA axis, (3) dynamic changes in eCB signaling during the adolescent period, (4) the effects of adolescent stress exposure on the eCB system, and (5) modulation of HPA axis activity and emotional behavior by adolescent cannabinoid treatment. Collectively, the emerging picture suggests that the eCB system mediates interactions between HPA axis stress responsivity, emotionality, and maturational stage. These findings may be particularly relevant to our understanding of the development of affective disorders and the risks of adolescent cannabis consumption on emotional health and stress responsivity.

Transitioning Adolescents and Young Adults With Sickle Cell Disease From Pediatric to Adult Health Care: Provider Perspectives

The transition from pediatric to adult health care is often challenging for adolescents and young adults with sickle cell disease (SCD). Our study aimed to identify (1) measures of success for the transition to adult health care; and (2) barriers and facilitators to this process. We interviewed 13 SCD experts and asked them about their experiences caring for adolescents and young adults with SCD. Our interview guide was developed based on Social-Ecological Model of Adolescent and Young Adult Readiness to Transition framework, and interviews were coded using the constant comparative method. Our results showed that transition success was measured by health care utilization, quality of life, and continuation on a stable disease trajectory. We also found that barriers to transition include negative experiences in the emergency department, sociodemographic factors, and adolescent skills. Facilitators include a positive relationship with the provider, family support, and developmental maturity. Success in SCD transition is primarily determined by the patients' quality of relationships with their parents and providers and their developmental maturity and skills. Understanding these concepts will aid in the development of future evidence-based transition care models.

Cognitive and Performance Enhancing Medication Use to Improve Performance in Poker

Use of neuroenhancers has been studied in groups ranging from students to surgeons; however, use of cognitive and performance enhancing medications (CPEMs) to improve performance in poker has remained largely overlooked. To assess the use of CPEMs to improve poker performance, a survey of poker players was conducted. Participants were recruited via Internet poker forums; 198 completed the online survey. Approximately 28 % of respondents used prescription CPEMs, with the most commonly used including: amphetamine/dextroamphetamine (62 %), benzodiazepines (20 %), and methylphenidate (20 %). CPEMs were used in poker to focus (73 %), calm nerves (11 %), and stay awake (11 %). Caffeine (71 %), as well as conventionally counter-intuitive substances like marijuana (35 %) and alcohol (30 %) were also reported to enhance poker performance. Non-users of CPEMs were dissuaded from use due to not knowing where to get them (29 %), apprehension about trying them (26 %), and legal or ethical concerns (16 %). Respondents most frequently acquired CPEMs via friends/fellow poker players (52 %), or prescription from physician (38 %). Additionally, greater use of CPEMs was associated with living outside the United States (p = 0.042), prior use of prescription medications for improving non-poker related performance (p < 0.001), and amateur and semi-professional player status (p = 0.035). Unmonitored use of pharmacologically active agents and their methods of acquisition highlight safety concerns in this cohort of poker players, especially among non-professional players. The current state of guidance from national organizations on CPEM use in healthy individuals could impact prescribing patterns.

Neuroscience, moral development, criminal capacity, and the Child Justice Act: justice or injustice?

The Child Justice Act of 2008 has set the minimum age for criminal capacity at 10 years with a rebuttable presumption of criminal incapacity between the ages of 10 and 14 years. The legislation requires that expert evidence be led (by clinical psychologists or psychiatrists) in order to assist the court to determine whether accused children and adolescents between 10 and 14 years of age can be held criminally responsible. The Child Justice Act requires an examination of the cognitive, moral, emotional, psychological, and social development of the accused child/adolescent. This article critically examines the neuroscience literature on brain development, decision-making and moral development in children and adolescents as it relates to legal prescripts inherent in the Child Justice Act, in particular with regard to accused children and adolescents’ understanding of the wrongfulness of an act, and their ability to act in accordance with that understanding.

Assessing the criminal capacity of children: a challenge to the capacity of mental health professionals

With increasing numbers of juveniles accused of serious crimes international concern is growing around the procedural consequences for affected individuals within the context of the law and criminal justice. Issues of culpability in children and adolescents are often raised, with much deliberation and insufficient agreement among legal and child development experts. Exactly when and to what extent juveniles can be held responsible for their action is a matter requiring careful consideration to avoid substantial erring in either direction. Although some international guiding standards and principles have been established, these are rather broad and unable to provide specific prescriptions. In addition, the assessment of criminal capacity in juveniles is a complex task, and one that is not wholly without reliability and validity problems. As in the case of South Africa and a few other countries, mental health specialists are often tasked with conducting developmental assessments to provide courts with expert evidence regarding criminal capacity. This paper examines the concept of criminal capacity in the context of the theory, controversies and challenges that affect this area of psychological focus.

Rethinking HIV prevention to prepare for oral PrEP implementation for young African women

INTRODUCTION

HIV incidence remains high among young women in sub-Saharan Africa in spite of scale-up of HIV testing, behavioural interventions, antiretroviral treatment and medical male circumcision. There is a critical need to critique past approaches and learn about the most effective implementation of evidence-based HIV prevention strategies, particularly emerging interventions such as pre-exposure prophylaxis (PrEP).

DISCUSSION

Women in sub-Saharan Africa are at increased risk of HIV during adolescence and into their 20s, in part due to contextual factors including gender norms and relationship dynamics, and limited access to reproductive and sexual health services. We reviewed behavioural, behavioural economic and biomedical approaches to HIV prevention for young African women, with a particular focus on the barriers, opportunities and implications for implementing PrEP in this group. Behavioural interventions have had limited impact in part due to not effectively addressing the context, broader sexual norms and expectations, and structural factors that increase risk and vulnerability. Of biomedical HIV prevention strategies that have been tested, daily oral PrEP has the greatest evidence for protection, although adherence was low in two placebo-controlled trials in young African women. Given high efficacy and effectiveness in other populations, demonstration projects of open-label PrEP in young African women are needed to determine the most effective delivery models and whether women at substantial risk are motivated and able to use oral PrEP with sufficient adherence to achieve HIV prevention benefits.

CONCLUSIONS

Social marketing, adherence support and behavioural economic interventions should be evaluated as part of PrEP demonstration projects among young African women in terms of their effectiveness in increasing demand and optimizing uptake and effective use of PrEP. Lessons learned through evaluations of implementation strategies for delivering oral PrEP, a first-generation biomedical HIV prevention product, will inform development of new and less user-dependent PrEP formulations and delivery of an expanding choice of prevention options in HIV prevention programmes for young African women.

"Learning how to deal with feelings differently": Psychotropic medications as vehicles of socialization in adolescence

Drawing from ethnographic research among clinicians working with adolescents at a hospital psychiatric emergency department and outpatient clinic, and with interviews with adolescent psychiatric patients and their parents, we examine how psychiatric medicines function as socializing agents. Although psychiatric medications are thought to exert their main effects through direct biological action on neural circuitry, in fact, their use mobilizes specific kinds of moral discourse and social positioning that may have profound effects on sense of self, personhood, and psychological development. Specifically, our data reveal how clinical discourse around medications aims to enlist adolescents in becoming responsible, emotionally intelligent selves through learning to manage their medications. Among doctors, adolescents and their families, talk about psychiatric medications intertwines narratives of 'growing up' and 'getting well'. Our analysis of case studies from the clinic thus demonstrates that while psychiatric medications are explicitly designed to influence behavior by acting directly on the brain, they also act to structure adolescents' selves and social worlds through indirect, rather than direct causal pathways to the brain.

HIV testing and linkage to services for youth

Introduction

HIV testing is the portal to serostatus knowledge that can empower linkage to care for HIV treatment and HIV prevention. However, young people's access to HIV testing is uneven worldwide. The objective of this paper is to review the context and concerns faced by youth around HIV testing in low- as well as high-income country settings.

Discussion

HIV testing is a critical entry point for primary and secondary prevention as well as care and treatment for young people including key populations of vulnerable youth. We provide a framework for thinking about the role of testing in the continuum of prevention and care for young people. Brief case study examples from Kenya and the US illustrate some of the common barriers and issues involved for young people.

Conclusions

Young people worldwide need more routine access to HIV testing services that effectively address the developmental, socio-political and other issues faced by young women and men.

Fetal exposure to maternal depressive symptoms is associated with cortical thickness in late childhood

BACKGROUND

Maternal depression is one of the most common prenatal complications. The consequences of fetal exposure to maternal depression are poorly understood. The aim of this study is to examine the association between fetal exposure to maternal depressive symptoms and cortical thickness in children 6-9 years old.

METHODS

A prospective, longitudinal study of maternal depressive symptoms at 19, 25, and 31 weeks' gestation was followed by acquisition of a structural magnetic resonance imaging scan in 81 children (age, 86.1 ± 9.9 months).

RESULTS

Significant (p < .01) cortical thinning in children primarily in the right frontal lobes was associated with exposure to prenatal maternal depression. The strongest association was at 25 weeks' gestation; exposure to maternal depression at 25 gestational weeks was associated with cortical thinning in 19% of the whole cortex and 24% of the frontal lobes, primarily in the right superior, medial orbital, and frontal pole regions of the prefrontal cortex (p < .01). The significant association between prenatal maternal depression and child externalizing behavior (p < .05) was mediated by cortical thinning in prefrontal areas of the right hemisphere.

CONCLUSIONS

The pattern of cortical thinning in children exposed to prenatal maternal depression is similar to patterns in depressed patients and in individuals with risk for depression. Exposure to prenatal depression coupled with subsequent cortical thinning was associated with presence of externalizing behavior in preadolescent children and may be prodromal markers of risk for dysphoria. Vulnerability to prenatal influences at 25 gestational weeks may result from the enormous growth and dramatic structural changes in the nervous system.

Efficacy and safety of pharmacological and psychological interventions for the treatment of psychosis and schizophrenia in children, adolescents and young adults: a systematic review and meta-analysis

BACKGROUND

Studies report contrasting results regarding the efficacy and safety of pharmacological, psychological, and combined interventions in psychosis and schizophrenia in children, adolescents and young adults.

METHODS

Systematic review and meta-analysis. Embase, Medline, PreMedline, PsycINFO, and CENTRAL were searched to July 2013 without restriction to publication status. Randomised trials comparing any pharmacological, psychological, or combined intervention for psychosis and schizophrenia in children, adolescents and young adults were included. Studies were assessed for bias, and GRADE criteria were used to describe the quality of the results.

RESULTS

Twenty-seven trials including 3067 participants were identified. Meta-analyses were performed for 12 comparisons: symptoms, relapse, global state, psychosocial functioning, depression, weight and discontinuation. Low quality evidence demonstrated that antipsychotics have small beneficial effects on psychotic symptoms (SMD = -0.42, 95% CI -0.58 to -0.26), and a medium adverse effect on weight gain (WMD = 1.61, 95% CI 0.61 to 2.60) and discontinuation due to side effects (RR = 2.44, 95% CI, 1.12 to 5.31). There were no trials of psychological treatments in under-18 year olds. There was no evidence of an effect of psychological interventions on psychotic symptoms in an acute episode, or relapse rate, but low quality evidence of a large effect for family plus individual CBT on the number of days to relapse (WMD = 32.25, 95% CI -36.52 to -27.98).

CONCLUSIONS

For children, adolescents and young adults, the balance of risk and benefit of antipsychotics appears less favourable than in adults. Research is needed to establish the potential for psychological treatments, alone and in combination with antipsychotics, in this population.

Nothing good ever happens after midnight: observed exposure and alcohol use during weekend nights among young male drivers carrying passengers in a late licensing country

Similar to other countries, also in the Netherlands young male drivers (ages between 18 and 24 years) are overrepresented in crashes during weekend nights, thereby fatally injuring one or more of their passengers. This overrepresentation may be due to two contributing factors: (a) a higher exposure-to-risk because of dangerous trip condition, and (b) a higher tendency to take risks. Studies on these factors, mostly carried out in jurisdictions where youngsters are licensed at an earlier age than in Europe, suggest a strong -often negative- influence from peer-aged passengers. Given that in adolescence susceptibility to peer pressure reduces with age, these findings may not be applicable to late licensing countries, such as in Europe. In the Netherlands -a late licensing country- youngsters are licensed after the age of 18 years, followed by a 5 year probation period with a legal alcohol limit of 0.2g/L. Further, designated driver schemes are in place since 2001, alcohol limits are enforced by random breath testing schemes, and no passenger and night time restrictions are in force. Against this background, we examined the incidence of dangerous trip conditions and risk taking among young male drivers and compared those with a reference group with a low passenger fatality rate. To that end, data on trip conditions and risk behavior were obtained from a data base on 18,608 randomly selected drivers during weekend nights in 2010, between 22:00 and 06:00. This data base held information for each randomly selected on breath alcohol concentration (BAC), license status, driver characteristics (age and gender), number of passengers, time of night, and level of urbanization. Binary logistic regression analysis confirmed the overrepresentation of young male drivers in traffic, carrying more frequently passengers than the reference group, especially after midnight. Urbanization level was not a modifying factor, but 'time of night' was, with riskier conditions after midnight in terms of: (a) a higher young male driver presence, (b) young male drivers carrying more frequently multiple passengers and (c) a higher prevalence of illegal BACs. After midnight, no evidence was found for a protective effect of the presence of one passenger on alcohol use. Of the young male drivers, 5% were over the legal limit and 3 in 5 young males who were over the limit carried passengers. However, the indicative result that young male drivers with multiple passengers were less likely to have been drinking than solo drivers or drivers with just one passenger, is suggestive of a protective effect of multiple passengers. These results may guide preventive strategies, including police enforcement and designated driver programmes.

Quantifying the influence of safe road systems and legal licensing age on road mortality among young adolescents: steps towards system thinking

Based on existing literature, a system thinking approach was used to set up a conceptual model on the interrelationships among the components influencing adolescent road mortality, distinguishing between components at the individual level and at the system level. At the individual level the role of risk behaviour (sometimes deliberate and sometimes from inexperience or other non-deliberate causes) in adolescent road mortality is well documented. However, little is known about the extent to which the 'road system' itself may also have an impact on younger adolescents' road mortality. This, by providing a safe or unsafe road environment for all road users (System-induced exposure) and by allowing access to high-risk vehicles at a young or older age through the legal licensing age. This study seeks to explore these relationships by analysing the extent to which the road mortality of 10 to 17 year olds in various jurisdictions can be predicted from the System-induced Exposure (SiE) in a jurisdiction and from its legal licensing age to drive motor vehicles. SiE was operationalized as the number of road fatalities per 10(5) inhabitants/all ages together, but excluding the 10 to 17 year olds. Data on road fatalities during the years 2001 through 2008 were obtained from the OECD International Road Traffic Accident Database (IRTAD) and from the USA NHTSA's Fatality Analysis Reporting System (FARS) database for 29 early and 10 late licensing jurisdictions. Linear mixed models were fitted with annual 'Adolescent road mortality per capita' for 2001 through 2008 as the dependent variable, and time-dependent 'SiE' and time-independent 'Licensing system' as predictor variables. To control for different levels of motorisation, the time-dependent variable 'Annual per capita vehicle distance travelled' was used as a covariate. Licensing system of a jurisdiction was entered as a categorical predictor variable with late licensing countries as a baseline group. The study found support for the protective effects of SiE on adolescent safety. If SiE increased by one unit, the mortality rate of 10 to 17 year olds increased by 0.487 units. No support was found for a protective effect of late licensing for this age group. Thus, compared to young adolescents who are allowed to drive motor vehicles in early licensing jurisdictions, late licensing does not provide extra protection for pre-license adolescents. This finding is probably the result of the high risks associated with alternative transport modes, such as moped riding and bicycling. Also, the fact that the study only included risks to young adolescents themselves and did not include the risks they might pose to other road users and passengers may have contributed to this finding, because such risks are greater when driving a motor vehicle than riding a moped or a bicycle. Therefore, to advance our understanding of the impact of licensing systems, more study is needed into the benefits of early or late licensing, thereby considering these wider effects as well.

Studies were included in the review if: 1) participants were aged ≥ 10 to ≤ 18 years, 2) studies addressed a physical or mental health issue, 3) Facebook was identified as a recruitment tool, 4) recruitment details using Facebook were outlined in the methods section and considered in the discussion, or information was obtained by contacting the authors, 5) results revealed how many participants were recruited using Facebook, and 6) studies addressed how adolescent consent and/or parental consent was obtained.

STUDY APPRAISALS AND SYNTHESIS METHODS

Titles, abstracts, and keywords were scanned and duplicates removed by 2 reviewers. Full text was evaluated for inclusion criteria, and 2 reviewers independently extracted data.

RESULTS

The search resulted in 587 publications, of which 25 full-text papers were analyzed. Six studies met all the criteria for inclusion in the review. Three recruitment methods using Facebook was identified: 1) paid Facebook advertising, 2) use of the Facebook search tool, and 3) creation and use of a Facebook Page.

CONCLUSIONS

Eligible studies described the use of paid Facebook advertising and Facebook as a search tool as methods to successfully recruit adolescent participants. Online and verbal consent was obtained from participants recruited from Facebook.

Young adults as users of adult healthcare: experiences of young adults with complex or life-limiting conditions

Awareness is growing that young adults may have distinctive experiences of adult healthcare and that their needs may differ from those of other adult users. In addition, the role of adult health teams in supporting positive transitions from paediatrics is increasingly under discussion. This paper contributes to these debates. It reports a qualitative study of the experiences of young adults - all with complex chronic health conditions - as users of adult health services. Key findings from the study are reported, including an exploration of factors that help to explain interviewees' experiences. Study findings are discussed in the context of existing evidence from young adults in adult healthcare settings and theories of 'young adulthood'. Implications for training and practice are considered, and priorities for future research are identified.

Adolescent and young adult health in the United States in the past decade: little improvement and young adults remain worse off than adolescents

Adolescence and young adulthood are unique developmental periods that present opportunities and challenges for improving health. Health at this age can affect health throughout the lifespan. This review has two aims: (1) to examine trends in key indicators in outcomes, behaviors, and health care over the past decade for U.S. adolescents and young adults; and (2) to compare U.S. adolescents and young adults on these indicators. The review also assesses sociodemographic differences in trends and current indicators. Guided by our aims, previous reviews, and national priorities, the present review identified 21 sources of nationally representative data to examine trends in 53 areas and comparisons of adolescents and young adults in 42 areas. Most health and health care indicators have changed little over the past decade. Encouraging exceptions were found for adolescents and young adults in unintentional injury, assault, and tobacco use, and, for adolescents, in sexual/reproductive health. Trends in violence and chronic disease and related behaviors were mixed. Review of current indicators demonstrates that young adulthood continues to entail greater risk and worse outcomes than adolescence. Young adults fared worse on about two-thirds of the indicators examined. Differences among sociodemographic subgroups persisted for both trends and current indicators.

Can we test for hereditary cancer at 18 years when we start surveillance at 25? Patient reported outcomes

DNA-testing for BRCA1/2 or Lynch syndrome is possible from the age of 18 years, although surveillance usually starts at 25. Some patients regret their decision of testing before age 25. This retrospective study evaluates whether the testing age should be above 25 years to prevent adverse effects such as regret or decisional conflict, by determining the percentage and characteristics of patients reporting these problems. 111 of 219 patients (51%) tested for BRCA1/2 mutations or Lynch syndrome between 18 and 25 years from July 1996 to February 2011, returned self-report surveys. Primary measures were regret, decisional conflict and family influence. Secondary measures included quality of life (QoL), coping style, impact of genetic testing, and risk perception. Median age was 27 [21-40] years, with 86% female. 73% was tested for BRCA1/2, 27% for Lynch syndrome. Only 3% reported regret, however 39% had moderate (32%) to severe (7%) decisional conflict. Regression analysis revealed that decisional conflict was associated with more monitoring/neutral coping style (p < 0.03) or paternal/no family mutation (p < 0.02); there were no differences in QoL, impact or risk perception. 42% were mutation carriers, showing equal decisional conflict to non-carriers. 68% would recommend testing <25 years; 77% desired surveillance <25 years if a mutation carrier. Almost no patient tested for hereditary cancer between 18 and 25 years regretted this decision. A third reported retrospective decisional conflict, especially those actively seeking information when faced with a threat and/or those with a paternal or unknown inheritance. These patients may benefit from decisional support and personalized information.

Brain images, babies, and bathwater: critiquing critiques of functional neuroimaging

Since the mid-1980s, psychologists and neuroscientists have used brain imaging to test hypotheses about human thought processes and their neural instantiation. In just three decades, functional neuroimaging has been transformed from a crude clinical tool to a widely used research method for understanding the human brain and mind. Such rapidly achieved success is bound to evoke skepticism. A degree of skepticism toward new methods and ideas is both inevitable and useful in any field. It is especially valuable in a science as young as cognitive neuroscience and its even younger siblings, social and affective neuroscience. Healthy skepticism encourages us to check our assumptions, recognize the limitations of our methods, and proceed thoughtfully. Skepticism itself, however, also must be examined. In this article, I review the most commonly voiced criticisms of functional neuroimaging. In the spirit of healthy skepticism, I will critically examine these criticisms themselves. Each contains at least a kernel of truth, although I will argue that in some cases the kernel has been over extended in ways that are inaccurate or misleading.

Adolescent and young adult medicine is a special and specific area of medical practice

Adolescent and young adult medicine is a concept that has gained traction in the last decade or so. The medical literature has come primarily from oncology. Advances in neuroscience that document continuing brain development into the third decade, and research that shows risk behaviours associated with adolescence both remain and may increase in the third decade, have been two of the drivers in the conversation around linking these two age groups together as a medical practice group. A third driver of importance is transition care in chronic illness, where older adolescents and young adults continue to have difficulties making effective linkages with adult care. The case for specific training in adolescent and young adult medicine, including the developmental concepts behind it, the benefits of the delineation and the particular challenges in the Australian health-care system, are discussed. On balance, there is a strong case for managing the health issues of adolescents and young adults together. This scenario does not fit easily with the age demarcations that are in place in acute care facilities. However, this is less the case in community services and can work in focused private practice. Such a situation suggests that both paediatric and adult physicians might be interested in adolescent and young adult medicine training and practice.

Risk, adaptation and the functional teenage brain

Over the last decade, the propensity for young people to take risks has been a particular focus of neuroscientific inquiries into human development. Taking population-level data about teenagers' involvement in drinking, smoking, dangerous driving and unprotected sex as indicative, a consensus has developed about the association between risk-taking and the temporal misalignment in the development of reward-seeking and executive regions of the brain. There are epistemological difficulties in this theory. Risk, the brain, and adolescence are different kinds of objects, and bringing them into the same frame for analysis is not unproblematic. In particular, risk is inextricably contextual and value-driven. The assessment of adolescent behaviour and decision-making as 'sub-optimal', and the implication that the developmental schedule of the teenage brain is dysfunctional, is also reassessed in terms of evolutionary development of the individual, the family and the human community. The paper proposes a view of adolescent development as adaptive, and a focus on young people's capacities in the profile of the needs of the community as a whole.

Immigrant background and medicine use for aches: national representative study of adolescents

Objectives

The aims of the study were to examine the association between immigrant background and medicine use for headache and stomach-ache among adolescents, and whether symptoms of headache and stomach-ache could explain the differences in medicine use.

Methods

We used data from the Danish contribution to the WHO-affiliated international cross-sectional survey Health Behaviour in School-aged Children (HBSC) in 2006. Among boys, a total of 4170 ethnic Danes, 244 descendants of immigrants, and 224 immigrants participated. Among girls, 4310 ethnic Danes, 264 descendants of immigrants, and 232 immigrants were included. The associations between migrant background and medicine use for headache and stomach-ache by means of multilevel multivariate logistic regression analyses adjusted for age group, symptoms and the clustering effect of school and stratified by sex due to interactions.

Results

Among boys, the risk of medicine use for stomach-ache was higher for immigrants (odds ratio (OR), 1.54; 95% confidence intervals (CI), 0.99-2.44)) and descendants (OR, 1.97 (1.33-2.94)) compared to ethnic Danes. Similar associations were found for use of medicine for stomach-ache for immigrant girls (OR, 1.55 (1.12-2.15) and use of medicine for headache among boys (immigrants (OR, 1.36 (1.02-1.97 and descendants (1.48 (1.12-1.97)). Symptoms of aches were all independently associated with medicine use. After adjusting for these factors the association between immigrant background and medicine use attenuated slightly.

Conclusion

Among adolescents in Denmark, the risk of medicine use for headache and stomach-ache was higher for immigrants and descendants as compared to ethnic Danes, with the exception of medicine use for headache among girls.

Examining the link between adolescent brain development and risk taking from a social-developmental perspective

The adolescent age period is often characterized as a health paradox because it is a time of extensive increases in physical and mental capabilities, yet overall mortality/morbidity rates increase significantly from childhood to adolescence, often due to preventable causes such as risk taking. Asynchrony in developmental time courses between the affective/approach and cognitive control brain systems, as well as the ongoing maturation of neural connectivity are thought to lead to increased vulnerability for risk taking in adolescence. A critical analysis of the frequency of risk taking behaviors, as well as mortality and morbidity rates across the lifespan, however, challenges the hypothesis that the peak of risk taking occurs in middle adolescence when the asynchrony between the different developmental time courses of the affective/approach and cognitive control systems is the largest. In fact, the highest levels of risk taking behaviors, such as alcohol and drug use, often occur among emerging adults (e.g., university/college students), and highlight the role of the social context in predicting risk taking behavior. Moreover, risk taking is not always unregulated or impulsive. Future research should broaden the scope of risk taking to include risks that are relevant to older adults, such as risky financial investing, gambling, and marital infidelity. In addition, a lifespan perspective, with a focus on how associations between neural systems and behavior are moderated by context and trait-level characteristics, and which includes diverse samples (e.g., divorced individuals), will help to address some important limitations in the adolescent brain development and risk taking literature.

Look Again: Effects of Brain Images and Mind–Brain Dualism on Lay Evaluations of Research

Brain scans have frequently been credited with uniquely seductive and persuasive qualities, leading to claims that fMRI research receives a disproportionate share of public attention and funding. It has been suggested that functional brain images are fascinating because they contradict dualist beliefs regarding the relationship between the body and the mind. Although previous research has indicated that brain images can increase judgments of an article's scientific reasoning, the hypotheses that brain scans make research appear more interesting, surprising, or worthy of funding have not been tested. Neither has the relation between the allure of brain imaging and dualism. In the following three studies, laypersons rated both fictional research descriptions and real science news articles accompanied by brain scans, bar charts, or photographs. Across 988 participants, we found little evidence of neuroimaging's seductive allure or of its relation to self-professed dualistic beliefs. These results, taken together with other recent null findings, suggest that brain images are less powerful than has been argued.

Guidelines for the ethical use of neuroimages in medical testimony: report of a multidisciplinary consensus conference

SUMMARY

With rapid advances in neuroimaging technology, there is growing concern over potential misuse of neuroradiologic imaging data in legal matters. On December 7 and 8, 2012, a multidisciplinary consensus conference, Use and Abuse of Neuroimaging in the Courtroom, was held at Emory University in Atlanta, Georgia. Through this interactive forum, a highly select group of experts-including neuroradiologists, neurologists, forensic psychiatrists, neuropsychologists, neuroscientists, legal scholars, imaging statisticians, judges, practicing attorneys, and neuroethicists-discussed the complex issues involved in the use of neuroimaging data entered into legal evidence and for associated expert testimony. The specific contexts of criminal cases, child abuse, and head trauma were especially considered. The purpose of the conference was to inform the development of guidelines on expert testimony for the American Society of Neuroradiology and to provide principles for courts on the ethical use of neuroimaging data as evidence. This report summarizes the conference and resulting recommendations.

Pedestrian injuries due to mobile phone use in public places

Research shows that pedestrians, similar to drivers, experience reduced situation awareness, distracted attention and unsafe behavior when talking or texting on their mobile phones. The present study centered on injuries related to mobile phone use among pedestrians. It used data from the US Consumer Product Safety Commission on injuries in hospital emergency rooms from 2004 through 2010. It found that mobile-phone related injuries among pedestrians increased relative to total pedestrian injuries, and paralleled the increase in injuries for drivers, and in 2010 exceeded those for drivers. Pedestrian injuries related to mobile-phone use were higher for males and for people under 31 years old. Using a mobile phone while walking puts pedestrians at risk of accident, injury or death.

Study protocol: longitudinal study of the transition of young people with complex health needs from child to adult health services

BACKGROUND

Young people with complex health needs have impairments that can limit their ability to carry out day-to-day activities. As well as coping with other developmental transitions, these young people must negotiate the transfer of their clinical care from child to adult services. The process of transition may not be smooth and both health and social outcomes may suffer.Increasingly, policy-makers have recognised the need to ensure a smoother transition between children's and adult services, with processes that are holistic, individualised, and person-centred; however, there is little outcome data to support proposed models of care. This study aims to identify the features of transitional care that are potentially effective and efficient for young people with complex health needs making their transition.

METHODS/DESIGN

Longitudinal cohort study. 450 young people aged 14 years to 18 years 11 months (with autism spectrum disorder and an additional mental health problem, cerebral palsy or diabetes) will be followed through their transition from child to adult services and will contribute data at baseline, 12, 24 and 36 months. We will collect data on: health and wellbeing outcomes (participation, quality of life, satisfaction with services, generic health status (EQ-5D-Y) and condition specific measure of disease control or management); exposure to proposed beneficial features of services (such as having a key worker, appropriate involvement of parents); socio-economic characteristics of the sample; use of condition-related health and personal social services; preferences for the characteristics of transitional care.We will us regression techniques to explore how outcomes vary by exposure to service features and by characteristics of the young people. These data will populate a decision-analytic model comparing the costs and benefits of potential alternative ways of organising transition services.In order to better understand mechanisms and aid interpretation, we will undertake qualitative work with 15 young people, including interviews, non-participant observation and diary collection.

DISCUSSION

This study will evaluate the effect of service components of transitional care, rather than evaluation of specific models that may be unsustainable or not generalisable. It has been developed in response to numerous national and international calls for such evaluation.

Puberty and adolescent sexuality

This article is part of a Special Issue "Puberty and Adolescence". Sexuality emerges as a major developmental element of puberty and the adolescent years that follow. However, connecting the sexuality that emerges with puberty and elements of adult sexuality is difficult because much adolescent sexuality research addresses the transition to partnered sexual behaviors (primarily coitus) and consequences such as unplanned pregnancy and sexually transmitted infections. This review proposes a framework of an expanded understanding of puberty and adolescent sexuality from the perspective of four hallmarks of adult sexuality: sexual desire; sexual arousal; sexual behaviors; and, sexual function. This approach thus addresses important gaps in understanding of the ontogeny of sex and the continuum of sexuality development from adolescence through the adult lifespan.

Risk-taking and social exclusion in adolescence: neural mechanisms underlying peer influences on decision-making

Social exclusion and risk-taking are both common experiences of concern in adolescence, yet little is known about how the two may be related at behavioral or neural levels. In this fMRI study, adolescents (N=27, 14 male, 14-17years-old) completed a series of tasks in the scanner assessing risky decision-making before and after an episode of social exclusion. In this particular context, exclusion was associated with greater behavioral risk-taking among adolescents with low self-reported resistance to peer influence (RPI). When making risky decisions after social exclusion, adolescents who had lower RPI exhibited higher levels of activity in the right temporoparietal junction (rTPJ), and this response in rTPJ was a significant mediator of the relationship between RPI and greater risk-taking after social exclusion. Lower RPI was also associated with lower levels of activity in lPFC during crashes following social exclusion, but unlike rTPJ this response in lPFC was not a significant mediator of the relationship between RPI and greater risk-taking after social exclusion. The results suggest that mentalizing and/or attentional mechanisms have a unique direct effect on adolescents' vulnerability to peer influence on risk-taking.

The enigmatic persistence of anorexia nervosa

OBJECTIVE

In this review, based on recent advances in cognitive neuroscience, the author presents a formulation in which the marked persistence of anorexia nervosa can be usefully understood as a well-ingrained maladaptive habit.

METHOD

The author reviewed the relevant literature on the development and course of anorexia nervosa and interpreted critical features in light of developments in cognitive neuroscience.

RESULTS

Anorexia nervosa is a well characterized disorder with remarkable persistence both across history and among affected individuals. Food restriction, the salient behavioral feature of the disorder, often begins innocently but gradually takes on a life of its own. Over time, it becomes highly entrenched and resistant to change through either psychological or pharmacological treatment. Cognitive neuroscience has described two related but distinct processes that underlie the acquisition of new patterns of behavior, namely, action-outcome and stimulus-response learning. It is likely that both processes are engaged in the development of anorexia nervosa and that stimulus-response learning (that is, habit formation) is critical to the persistence of the dieting behavior.

CONCLUSIONS

The formulation of the dieting behavior characteristic of anorexia nervosa as a well-entrenched habit provides a basis for understanding the striking persistence of this disorder. This model helps explain the resistance of anorexia nervosa to interventions that have established efficacy in related disorders and implies that addressing the dieting behavior is critical, especially early in the course of the illness, before it has become ingrained.

Adolescents' and young adults' transition experiences when transferring from paediatric to adult care: a qualitative metasynthesis

OBJECTIVES

The objective of this study was to synthesize qualitative studies of how adolescents and young adults with chronic diseases experience the transition from paediatric to adult hospital care.

DESIGN

The review is designed as a qualitative metasynthesis and is following Sandelowski and Barroso's guidelines for synthesizing qualitative research.

DATA SOURCES

Literature searches were conducted in the databases PubMed, Ovid, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), ISI Web of Science, and Nordic and German databases covering the period from 1999 to November 2010. In addition, forward citation snowball searching was conducted in the databases Ovid, CINAHL, ISI Web of Science, Scopus and Google Scholar.

REVIEW METHODS

Of the 1143 records screened, 18 studies were included. Inclusion criteria were qualitative studies in English, German or Nordic languages on adolescents' and young adults' transition experiences when transferring from paediatric to adult care. There was no age limit, provided the focus was on the actual transfer process and participants had a chronic somatic disease. The studies were appraised as suitable for inclusion using a published appraisal tool. Data were analyzed into metasummaries and a metasynthesis according to established guidelines for synthesis of qualitative research.

RESULTS

Four themes illustrating experiences of loss of familiar surroundings and relationships combined with insecurity and a feeling of being unprepared for what was ahead were identified: facing changes in significant relationships, moving from a familiar to an unknown ward culture, being prepared for transfer and achieving responsibility.

CONCLUSIONS

Young adults' transition experiences seem to be comparable across diagnoses. Feelings of not belonging and of being redundant during the transfer process are striking. Health care professionals' appreciation of young adults' need to be acknowledged and valued as competent collaborators in their own transfer is crucial, and may protect them from additional health problems during a vulnerable phase. Further research including participants across various cultures and health care systems is needed.
