RESUMO
While paediatric care providers are often the first point of contact for children or youth experiencing mental health challenges, they may lack the resources (e.g., access to a multidisciplinary team) or training to adequately identify or manage such problems. This joint statement describes the key roles and competencies required to assess and address child and youth mental health problems, and the factors that optimize outcomes in this age group. Evidence-informed guidance on screening for and discussing mental health concerns with young people and families is provided. Preventive and therapeutic interventions with demonstrated efficacy in community care settings are discussed. This foundational statement also focuses on the changes to medical education, health systems, and health policy that are needed to improve clinical practice and advocacy efforts in Canada, including appropriate remuneration models, stepped-care approaches, targeted government funding, and professional training and education.
RESUMO
Les dispensateurs de soins pédiatriques sont souvent le premier point de contact des enfants et des adolescents aux prises avec des problèmes de santé mentale, mais ils ne possèdent pas nécessairement les ressources (p. ex., l'accès à une équipe multidisciplinaire) ni la formation nécessaires pour procéder à leur dépistage ou à leur prise en charge. Le présent document de principes conjoint décrit les principaux rôles et les principales compétences à maîtriser pour évaluer et traiter les problèmes de santé mentale chez les enfants et les adolescents, de même que les facteurs qui optimisent le plus possible l'évolution de la santé mentale dans ces groupes d'âge. Il contient des conseils fondés sur des données probantes à propos du dépistage des préoccupations en matière de santé mentale chez les jeunes et leur famille ainsi qu'à propos des échanges sur le sujet. Les interventions préventives et thérapeutiques dont l'efficacité est démontrée en milieu communautaire sont abordées. Le présent document de principes, qui est fondamental, traite également des changements à l'enseignement de la médecine ainsi qu'aux systèmes et aux politiques de santé qui s'imposent pour améliorer la pratique clinique et les efforts de revendications au Canada, y compris les modèles de rémunération appropriés, les approches des soins abordées étape par étape, le financement gouvernemental ciblé, l'enseignement et la formation professionnelle.
RESUMO
ISSUE ADDRESSED: With the emerging focus on designing health-literate organisations and health care systems, it is essential to understand the health literacy profiles of the medical workforce including medical students, as medical professionals play a key role in within these systems. Medical professionals contribute to good patient health outcomes through enabling access to appropriate health care, provision of quality health information and collaborative shared decision-making, which are fundamental health literacy competencies. The aim of this study is to identify health literacy strengths and weaknesses of medical students enrolled in an Australian Doctor of Medicine programme. METHODS: Students from all 4 years of an Australian Doctor of Medicine programme were invited to complete an anonymous, online survey in January 2021. Health literacy profiles were identified using the 9-domain, 44-item multi-dimensional Health Literacy Questionnaire, a validated tool which comprehensively evaluates health literacy strengths and weaknesses from diverse perspectives. Demographic characteristics and social attributes were also recorded. The results were compared with Australian Bureau of Statistics data. RESULTS: Eighty-six participants completed the survey. Most participants were female students (57%) who spoke English at home (88%) with tertiary-educated fathers (60%) and resided in locations associated with high socioeconomic status during adolescence (61%). Males scored significantly higher in three domains which explored health information access and appraisal, and ability to actively engage with health care providers. Students' scores were significantly lower than the Australian general population in Domain 6 (Ability to actively engage with health care providers) and Domain 7 (Navigating the health care system). CONCLUSIONS: Medical students' health literacy profiles indicate areas of weakness in their ability to engage with health care providers and to navigate the health system. Medical educators will need to create opportunities to address these weaknesses within medical curricula. Gender differences identified in self-rated ability to access and appraise health information requires further exploration. SO WHAT?: Further understanding of health literacy profiles of medical students may influence design of medical school curricula.
RESUMO
Importance: To our knowledge, this is the first pediatric surveillance study of children and adolescents with avoidant restrictive food intake disorder (ARFID). Objectives: To examine the incidence and age- and sex-specific differences in the clinical presentation of ARFID in children and adolescents in Canada. Design, Setting, and Participants: In this cross-sectional study, patients with ARFID were identified through the Canadian Paediatric Surveillance Program by surveying 2700 Canadian pediatricians monthly from January 1, 2016, to December 31, 2017. Main Outcomes and Measures: The incidence of ARFID in Canadian children (5-18 years of age) and age- and sex-specific clinical characteristics at presentation. Results: In total, 207 children and adolescents (mean [SD] age, 13.1 [3.2] years; 127 [61.4%] female) were included in this study. The incidence of ARFID in children 5 to 18 years of age was 2.02 (95% CI, 1.76-2.31) per 100 000 patients. Older children and adolescents were more likely to endorse eating too little (5-9 years of age: 76.7%; 95% CI, 58%-88.6; 10-14 years of age: 90.9%; 95% CI, 84.6%-94.8%; 15-18 years of age: 95.6%; 95% CI, 83.6%-98.9%; P = .02), have a loss of appetite (5-9 years of age: 53.3%; 95% CI, 35.4%-70.4%; 10-14 years of age: 74.2%; 95% CI, 66.0%-81.0%; 15-18 years of age: 80.0%; 95% CI, 65.5%-89.4%; P = .03), be medically compromised (mean body mass index z score: 10-14 vs 5-9 years of age: -1.31; 95% CI, -2.0 to -0.6; 15-18 vs 5-9 years of age: -1.35; 95% CI, -2.2 to -0.5; 15-18 vs 10-14 years of age: -0.04; 95% CI, -0.6 to 0.5; P < .001; mean percentage of treatment goal weight: 10-14 vs 5-9 years of age: -8.6; 95% CI, -14.3 to -2.9; 15-18 vs 5-9 years of age: -9.8; 95% CI, -16.3 to -3.3; 15-18 vs 10-14 years of age: -1.2; 95% CI, -5.8 to 3.4; P < .001; mean heart rate (beats per min): 10-14 vs 5-9 years of age: -10; 95% CI, -21.9 to 1.9; 15-18 vs 5-9 years of age: -19.7; 95% CI, -33.1 to -6.2; 15-18 vs 10-14 years of age: -9.7; 95% CI, -18.7 to -0.7; P = .002), have higher rates of anxiety (5-9 years of age: 26.7%; 95% CI, 13.7-45.4; 10-14 years of age: 52.3%; 95% CI, 43.7%-60.7%; 15-18 years of age: 53.3%; 95% CI, 38.6%-67.5%; P = .03) and depression (5-9 years of age: 0%; 10-14 years of age: 6.8%; 95% CI, 3.6%-12.7%; 15-18 years of age: 26.7%; 95% CI, 15.7%-41.6%; P < .001), and be more likely to be hospitalized (5-9 years of age: 13.3%; 95% CI, 5.0%-31.1%; 10-14 years of age: 41.7%; 95% CI, 33.5%-50.3%; 15-18 years of age: 55.6%; 95% CI, 40.7%-69.5%; P = .001). Younger children were more likely to endorse lack of interest in food (5-9 years of age: 56.7%; 95% CI, 38.4%-73.2%; 10-14 years of age: 75.0%; 95% CI, 66.8%-81.7%; 15-18 years of age: 57.8%; 95% CI, 42.8%-71.4%; P = .03), avoidance of certain foods (5-9 years of age: 90.0%; 95% CI, 72.6%-96.8%; 10-14 years of age: 69.7%; 95% CI, 61.3%-77.0%; 15-18 years of age: 62.2%; 95% CI, 47.2%-75.3%; P = .03), and refusal based on sensory characteristics (5-9 years of age: 66.7%; 95% CI, 47.9%-81.3%; 10-14 years of age: 38.6%; 95% CI, 30.7%-47.3%; 15-18 years of age: 22.2%; 95% CI, 12.3%-36.9%; P < .001). Eating but not enough was more common in girls (75.0%; 95% CI, 64.1%-83.4%) vs boys (68.5%; 95% CI, 59.8%-76.1; P = .04), and boys had a higher rate of refusal based on sensory characteristics (51.2%; 95% CI, 40.2%-62.2%) compared with girls (31.5%; 95% CI, 23.9%-40.2%; P = .007). Conclusions and Relevance: This study suggests that ARFID is a relatively common eating disorder and is associated with important age- and sex- specific clinical characteristics that may help in early recognition and timely treatment of the presenting symptoms.

Eating disorders are serious, potentially life-threatening illnesses afflicting individuals through the life span, with a particular impact on both the physical and psychological development of children and adolescents. Because care for children and adolescents with eating disorders can be complex and resources for the treatment of eating disorders are often limited, pediatricians may be called on to not only provide medical supervision for their patients with diagnosed eating disorders but also coordinate care and advocate for appropriate services. This clinical report includes a review of common eating disorders diagnosed in children and adolescents, outlines the medical evaluation of patients suspected of having an eating disorder, presents an overview of treatment strategies, and highlights opportunities for advocacy.

Objective Anorexia nervosa (AN) patients are at an increased risk of developing cardiac complications including bradyarrhythmias, systolic dysfunction, pericardial effusions, and sudden cardiac death. Although previous echocardiographic studies in AN patients have demonstrated a reduction in overall left ventricular (LV) mass, systolic dysfunction, and silent pericardial effusions, little is known about the role of cardiac magnetic resonance imaging (CMR) in assessing this patient population. The objective of this study was to assess cardiac indices and the presence of myocardial fibrosis in AN patients. Methods Between 2014 and 2015, a cross-sectional pilot study of 16 female patients who met the Diagnostic and Statistics Manual of Mental Disorders, fifth edition (DSM-5) criteria for AN was conducted at a single tertiary care center. Baseline characteristics including age, weight, food restriction behavior, over-exercise, self-induced vomiting, and laxative abuse were collected in the study population. Electrocardiography, transthoracic echocardiography (TTE), and CMR were performed. Results The mean age was 17 years (range: 13-22 years). There were no conduction abnormalities as the average PR interval was 152 ms (range: 130-190 ms) and QTc was 413 ms (range: 360-450 ms). Using TTE, the left ventricular ejection fraction (LVEF) was 54 ± 4% with a lower LV mass/body surface area (BSA) of 56 ± 7g/m2 in AN patients as compared to controls. Using CMR, both the mean LVEF of 52 ± 9% and LV mass/BSA of 45 ± 4g/m2 were lower in AN patients as compared to controls. Using CMR, both right ventricular ejection fraction (RVEF) of 50 ± 10% and a right ventricular (RV) mass/BSA of 18 ± 3g/m2 were smaller in AN patients as compared to controls. There was no evidence of late gadolinium enhancement (LGE) in the study population. Conclusions Young patients with AN have lower cardiac mass and volumes with no evidence of myocardial fibrosis.
RESUMO
Firearm injuries are a significant and preventable cause of death in Canadian youth. Adolescent and young adult males are disproportionately affected; however, firearm-related deaths occur in youth of all ages. Canada's rate of firearm ownership is lower than that of the USA, but high compared with other upper-income countries. The availability of firearms to youth is an important factor in adolescent suicide, unintentional firearm deaths, gang homicide and school shootings. Guns should not be kept in homes or environments where children and adolescents live or play. Screening for the presence of a firearm in the home is an essential part of the safety assessment of a depressed or suicidal youth, and removal of the firearm from the home must be recommended in this situation. Legislative measures to strictly control the acquisition, transport, ownership and storage of firearms, and to reduce smuggling of firearms, are also recommended.
RESUMO
The common but poorly understood condition known as bacterial vaginosis (BV) increases vulnerability to HIV infection and is associated with the absence of H(2)O(2)-producing Lactobacillus. Vaginal lactic acid bacteria (LAB) produce anti-HIV factors such as organic acids and hydrogen peroxide (H(2)O(2)), and may bind and inactivate HIV particles during scavenging of mannose. These factors define potential criteria for initial selection of candidate probiotics to block heterosexual transmission of HIV. Therefore, the primary goal of this study was to characterize acid production on mannose and H(2)O(2) production in vaginal isolates from Canadian adolescents (192 isolates, 16 individuals) and commercial sex workers in Nairobi, Kenya (576 isolates, 96 individuals). Selection of isolates from H(2)O(2)-detecting media suggested an idiosyncratic individual-level profile and extensive phenotypic diversity, including the identification of a subset of "double-strong" acid- and H(2)O(2)-producers with phenotypes similar to well-characterized probiotic strains. Molecular fingerprinting of all isolates by capillary electrophoresis of 16S-23S rRNA interspacer amplicons was coupled with chaperonin-60 universal target (cpn60 UT) sequencing in a subset, tentatively identifying 96% of isolates although only 19% were sequenced. Most isolates belonged to Lactobacillus, Streptococcus, Bifidobacterium or Gardnerella, with a total of 37 species in 15 genera, as well as 5 potentially novel organisms, identified in this study. This sensitivity was likely enhanced by phenotype-based selection on two chromogenic media formulations. Identification of double-strong isolates may provide a rational basis for selection and further characterization of vaginal probiotics, with potential application as part of HIV prevention initiatives in western Canada and East Africa.

Bacterial vaginosis (BV) is an important risk factor in reproductive health outcomes, such as pre-term birth and sexually transmitted infections including HIV. However, its etiology, diagnosis and treatment remain poorly defined. We evaluated flow cytometry as a tool to quantify total bacterial cells in vaginal specimens self-collected longitudinally by adolescents. BV was diagnosed by Gram-stain (criteria of Hay and Ison). Average flow cytometric counts of bacterial cell-units (BCU) was log(10) 8.04 per gram sample and was found to correlate with sample weight (p<0.0001). BV was frequently observed in this group, with 22 of 32 participants (69%) diagnosed with BV for at least one timepoint. Surprisingly, increased BCU was associated with normal Hay-Ison score (p=0.0003), even when adjusting for sample weight (p=0.02). Since presence and quantity of Lactobacillus defines normal vaginal microbiology (ie. absence of BV), this result indicates a possible bias towards dominance of Lactobacillus cells in measurements of "total" BCU. Increased BCU per gram was associated in multivariate analysis with longer self-reported time since last menstruation (p=0.004) and last sexual intercourse (p=0.007). Sperm was detected in 3 samples provided by those reporting sexual intercourse in the previous 24 h. Light-scattering profiles of bacteria and vaginal cells in samples collected over time from an individual were often identical and distinct from other individuals. To our knowledge, this is the first description of flow cytometry for analysis of commensal bacteria in vaginal specimens. Further development may help to illuminate the complex dynamics of vaginal microbial communities underlying BV.

INTRODUCTION: Apparent changes in adolescent sexual behaviours have led to debate in recent years. A survey on adolescent sexuality was designed to determine mainstream Canadian adolescents' current knowledge and sources of sexual health information, to identify their needs, and to understand the perceptions and the role of parents in sexual health education. METHODOLOGY: In October 2005, on-line interviews were conducted by Ipsos Reid (Ipsos Canada) with 1171 Canadian teenagers (14 to 17 years of age) and 1139 mothers of teenagers. RESULTS: Twenty-seven per cent of teens were sexually active at a mean age of 15 years, with an average of 2.5 lifetime partners, and had been in their current relationship for longer than eight months. The last time that they had had sex, 76% had used a condom. Teens and mothers overestimated the percentages of teens sexually active at any age. Most valuable sources of information were school, parents, friends and doctors. Sixty-nine per cent of teens could not find the information that they were looking for, and 62% reported obstacles in getting information. Teens lacked knowledge about sexually transmitted infections and their consequences. Seventy-five per cent of mothers believed that their teenagers' friends were significant role models when it came to sexuality, and 50% mentioned entertainment celebrities at par with them. However, 45% of teenagers regarded their parents as their role models, far ahead of friends (32%) and entertainment celebrities (15%). Despite saying that they had positive relationships with their mothers, 38% of teens had not discussed sexuality with them. Most teens trusted the information given by health professionals (94%) and believed that it was their role to provide sexual health information. CONCLUSIONS: Most adolescents are responsible when it comes to sexuality, but there are still areas of concern. Adolescents identify barriers to getting information and lack knowledge about sexually transmitted infections. Parents should feel more comfortable when it comes to discussing sexuality, especially the more value-based issues. Health care professionals and teachers have a role to play, and should ensure that teens are getting correct information. It is important to have diverse sources of information. All teens are not ready at the same time to receive the information; thus, it should be repeated. Governments, health, education and public health authorities have an essential role to play to make sexual health information accurate, accessible, inclusive and salient to the reality of Canadian adolescents.
RESUMO
PURPOSE: To examine whether African-American inner-city adolescents are independently motivated by a fear of victimization or by delinquency to carry a knife or gun. METHODS: A household sample of 130 female and 93 male African-American adolescents, aged 13-19 years old, were queried about their fear of victimization, history of delinquency, and intention to carry a knife or a gun in the next 3 months. RESULTS: A high intention to carry a knife was reported by 27% of the males and 35% of the females. A high intention to carry a gun was reported by 25% of the males and 9% of the females. The intention to carry a knife was independently associated with a history of delinquency in females (odds ratio [OR] = 3.0; 95% confidence interval [CI] = 1.4-6.2) and males (OR = 4.7; 95% CI = 1.7-13.3). It was not associated with a fear of victimization. The intention to carry a gun was independently associated with fear of victimization in females (OR = 4.5; 95% CI = 1.1-17.7) and males (OR = 3.3; 95% CI = 1.1-9.9). It was also independently associated with a history of delinquency in females (OR = 4.1; 95% CI = 1.1-16.3) and males (OR = 11.7; 95% CI = 3.1-44.7). CONCLUSIONS: Delinquency may play a role in motivating inner-city African-American adolescents to carry a knife, whereas both delinquency and fear of victimization may influence adolescents' motivation to carry a gun.
