RESUMEN
BACKGROUND: As a result of the public health measures put in place during the COVID-19 pandemic in Canada, many health services, including those for the treatment of eating disorders, were provided at a distance. This study aims to describe the adaptations made in specialized pediatric eating disorder programs in Canada and the impact of these adaptations on health professionals' experience of providing care. METHODS: A mixed-methods design was used to survey healthcare professionals working in specialized pediatric eating disorder programs about adaptations to treatment made during the pandemic and the impact of these adaptations on their experience of providing care. Data were collected between October 2021 and March 2022 using a cross-sectional survey comprising 25 questions and via semi-structured interviews. Quantitative data were summarized using descriptive statistics and qualitative data were interpreted using qualitative content analysis. RESULTS: Eighteen healthcare professionals in Canada completed the online survey, of whom six also participated in the semi-structured interviews. The cross-sectional survey confirmed that, unlike in pre-pandemic times, the majority of participants provided medical care (15/18) and mental health care (17/18) at a distance during the pandemic, with most participants using telephone (17/18) and videoconferencing (17/18). Most (16/18) health professionals indicated that virtual care would continue to be used as a tool in pediatric ED treatment after the pandemic. Participants used a combination of virtual and in-person care, with most reporting weighing patients both in clinic (16/18) and virtually (15/18). Qualitative content analysis generated five themes: (1) responding to increased demand with insufficient resources; (2) adapting to changes in care due to the COVID-19 pandemic; (3) dealing with uncertainty and apprehension; (4) virtual care as an acceptable and useful clinical tool, and (5) optimal conditions and future expectations. Most interview participants (5/6) had globally positive views of virtual care. CONCLUSIONS: Providing virtual multidisciplinary treatment for children and adolescents with eating disorders seemed feasible and acceptable to professionals during the pandemic. Moving forward, focusing on health professionals' perspectives and providing appropriate training in virtual interventions is essential given their central role in successful implementation and continued use of virtual and hybrid care models.
RESUMEN
The overarching goal of this study was to examine the unique contribution of psychological, familial, and friendship factors in explaining anorexia nervosa (AN) symptom severity 1 year following diagnosis among a sample of adolescent girls. A second objective was to determine whether friendship factors mediated the association between psychological and/or familial factors and AN symptom severity. This study included 143 adolescent girls under the age of 18 diagnosed with AN (M = 14.84, SD = 1.31). Participants were recruited from specialized eating disorder treatment programs. At admission (T1), participants completed a set of self-report questionnaires measuring psychological, familial, and friendship factors. AN symptom severity was assessed 1 year later (T2). Results of hierarchical regression analysis revealed that greater general psychological maladjustment at T1 (b = .26; se = .03; p = .00) was associated with greater AN symptom severity at T2. Greater alienation from friends at T1 (b = 1.20, se = .53, p = .03) also predicted greater AN symptom severity at T2, above and beyond the influence of adolescent girls' general psychological maladjustment. Finally, the mediating role of alienation from friends in the association between general psychological maladjustment at T1 and AN symptom severity at T2 was also identified. AN is a multidimensional disorder with a prognosis that involves both psychological and social factors. The results stemming from the present study shed light on the role of peer as a mechanism through which general psychological maladjustment is linked to AN symptom severity 1 year following diagnosis.
RESUMEN
PURPOSE: Anorexia Nervosa (AN) is a serious and potentially lethal mental disorder characterised by a deliberate quest to reduce one's weight. It can have multiple physical and psychological consequences. The clinical presentation of AN can include gastrointestinal symptoms, however, the pathophysiology of these symptoms in the context of AN remains uncertain. It is hypothesised that patients with AN may have an increase in intestinal permeability, which could lead to an increase in faecal calprotectin (fCP), a marker of intestinal inflammation. No relation between AN and elevation of fCP has been previously described in literature. METHODS: Eight patients hospitalised for AN have a dosage of fCP. RESULTS: Calprotectine was found to be elevated in 50% of cases, with or without any underlying comorbid gastrointestinal disease. Only the duration of illness tended to be associated with the increase in fCP suggesting a greater alteration as a function related to the time of denutrition. CONCLUSION: Although these findings provide insights in the potential pathophysiology of gastrointestinal symptoms in AN, further studies that evaluate the factors associated with elevated fCP in patients with AN are needed.

OBJECTIVE: Birth outcomes of women with anorexia nervosa are poorly understood. We hypothesized that hospitalization for anorexia nervosa before or during pregnancy is associated with an elevated risk of adverse maternal and infant birth outcomes. METHOD: We performed a retrospective cohort study of 2,134,945 pregnancies in Quebec, Canada, from 1989 to 2016. The main exposure measure was anorexia nervosa requiring hospital treatment before or during pregnancy. Outcome measures included stillbirth, preterm birth, low birth weight, small-for-gestational age birth, preeclampsia, gestational diabetes, cesarean delivery, and other pregnancy disorders. We computed risk ratios and 95% confidence intervals (CI) for the association between anorexia nervosa and birth outcomes adjusted for maternal characteristics. RESULTS: Compared with no hospitalization, anorexia nervosa hospitalization was associated with 1.99 times the risk of stillbirth (95% CI 1.20-3.30), 1.32 times the risk of preterm birth (95% CI 1.13-1.55), 1.69 times the risk of low birth weight (95% CI 1.44-1.99), and 1.52 times the risk of small-for-gestational age birth (95% CI 1.35-1.72). The associations with low birth weight and small-for-gestational age birth were more prominent in women hospitalized for anorexia nervosa during pregnancy or within 2 years of delivery. Hospitalization for anorexia nervosa was associated with certain maternal outcomes, including precipitate labor, acute liver failure, and admission to an intensive care unit. DISCUSSION: Hospitalization for anorexia nervosa before or during pregnancy is associated with adverse infant and maternal outcomes. Infants are primarily at risk of stillbirth, preterm birth, low birth weight, and small-for-gestational age birth.

PURPOSE: Anorexia nervosa (AN) is a complex medical condition affecting mainly adolescents and young adults. To monitor and prevent refeeding syndrome, current guidelines recommend daily laboratory testing in the first week of hospitalization and 2-3 times/week for the following 3 weeks. The aims of this study were to determine the proportion of abnormal results of the blood tests done during the first week of nutritional rehabilitation in adolescents with AN, the proportion of test having led to supplementation and the cost of all these tests. METHOD: A retrospective chart review of admissions for eating disorders between May 2014 and May 2015 in a tertiary Pediatric University Hospital center was performed. Patients were included if they were younger than 18 years, admitted for protocol-based refeeding and met criteria for AN (DSM 5). RESULTS: Among the 99 hospitalizations included in the study, the mean age was 14.6 years (± 1.7), with a female predominance (97%). The mean admission BMI was 15.3 ± 2 kg/m2 (Z-score - 2.6 ± 1.4). The mean length of hospitalization was 40.3 days ± 21.8. Of the 1289 laboratory tests performed, only 1.5% revealed abnormal values and 0.85% led to supplementation. No critical value was identified. The total cost for the tests performed was 148,926.80 CAD$, 1504$/admitted patient, instead of 3890$/admitted patient had we followed the recommendations. CONCLUSION: More precise criteria should be developed regarding the frequency of laboratory tests needed to monitor and prevent refeeding syndrome. At present, the recommendations could lead to unnecessary testing and expenses. LEVEL OF EVIDENCE: Level IV: Dramatic results in uncontrolled trials.

The purpose of our study is to establish if the proportion of patients diagnosed with anorexia nervosa that have a history of excess weight has increased over a 10-year period and to study how different premorbid weight groups vary in terms of clinical characteristics. We performed a single-center, retrospective cohort study of all new patients presenting with anorexia nervosa, restrictive and binge/purge subtypes, in 2004 and 2014 at the Adolescent Medicine Clinic of Sainte-Justine University Health Centre (n = 172). The prevalence of excess premorbid weight was similar in both cohorts (32% in 2004 versus 29.5% in 2014). The historically overweight subgroup had a lower heart rate at intake (64.77 versus 69.75, p = 0.03). Patients with excess premorbid weight lost an average of 1 kg more per month than their historically thinner counterparts (2.6 kg versus 1.6 kg/month, p = 0.0011). The total decrease in BMI was much greater in patients with a history of excess weight (7 BMI points versus 3.8, p = 0.0001).Conclusion: Since overweight and obese patients present with significant weight suppression values, our study stresses the importance of screening for AN in all patients rather than in only the noticeably underweight. What is Known: ⢠More than one third of patients presenting with AN have a history of overweight or obesity, which is comparable to the general population. ⢠A delay between AN onset and diagnosis has been described in overweight adolescents. What is New: ⢠Historically overweight patients presenting with AN demonstrate increased speed of weight loss, greater drop in BMI, and lower heart rate at presentation. ⢠For patients with a history of excess weight considered as having recovered from AN, the average BMI at discharge was within normal limits.

The aim of this study was to better understand the relationship between parents' experience of caregiving and expressed emotion during the early stage of their child's eating disorder. Fifty mothers and 38 fathers of adolescents suffering from anorexia nervosa and hospitalized for the first time participated in this study. They completed the Experience of Caregiving Inventory, a measure of the negative and positive aspects of the caregiving experience, and the Family Questionnaire, which measured the different dimensions of expressed emotion, namely emotional over-involvement and critical comments. Results showed that caregiving experience is significantly and positively correlated to expressed emotion. Among the negative aspects of caregiving, sense of loss contributed most to emotional over-involvement, while difficult behaviours contributed most to critical comments. The results suggest that parents' perceptions of their child and child's future are strongly related to their tendency to be over-involved. The perception of disruptive behaviours in their child could be one of the principal triggers or exacerbating factors of parents' critical attitudes.

BACKGROUND: A better understanding of the individual difficulties reported by adolescents presenting with anorexia nervosa seems like an interesting avenue to refine our understanding of their psychological functioning. OBJECTIVE: This study aimed to: (1) describe the behavioral and affective profile of difficulties of inpatient adolescent girls presenting a restricting type of anorexia (ANR); and (2) investigate the presence of a relationship between behavioral and affective problems and severity of the disorder. METHODS: The sample consisted of 52 inpatient adolescent girls presenting an ANR. The youth self report assessed the behavioral and emotional profile of difficulties of participants while the Eating Disorder Risk Composite of the Eating Disorder Inventory measured the symptomatology of the disorder. A ratio between body mass index at admission and at the end of the treatment served as an indicator of weight gain. RESULTS: The sample presented an internalized profile of problems. Individual differences were found and three profiles of difficulties were present in the sample: normative, pure internalizing and mixed (clinical on the internalizing and externalizing clusters). CONCLUSION: This study provides information on the heterogeneity of this specific population otherwise quite similar and demonstrates how severity of the disorder can be associated with a wide range of other behavioral and affective difficulties. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

PURPOSE: Although primarily a mental health disorder, anorexia nervosa (AN) has many physical consequences. Among them, the consequences on kidney function are often underestimated. We evaluated renal function in adolescent AN inpatients and investigated the correlation between the GFR and intrinsic patient characteristics. METHODS: A single-center retrospective study was conducted on 51 patients hospitalized for the restrictive type of AN in 2013. Data were divided into: (1) medical history of AN; (2) growth parameters and vital signs upon admission; and (3) blood tests. The glomerular filtration rate (GFR) was calculated using the Cockroft-Gault, MAYO Clinical Quadratic (MCQ), Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), the Modification of Diet in Renal Disease (MDRD), and Schwartz equations. RESULTS: The calculated percentages of patients with a GFR below 90 mL/min/1.73 m2 according to the different equations were as follows: Cockroft-Gault, 45%; MDRD, 28%; CKD-EPI, 14%; MCQ, 12%, and Schwartz, 4%. There was a strong association between the body mass index (BMI) and the GFR according to all equations (p < 0.0001). The lowest heart rate was significantly associated with a reduced GFR according to the Cockroft-Gault equation (p = 0.03). The GFR values did not differ significantly after rehydration. CONCLUSION: Clinicians should evaluate AN patients for renal complications, especially when the BMI and heart rate are very low. Dehydration was not solely responsible for renal impairment. LEVEL OF EVIDENCE: Level III, single-center retrospective cohort study.

Few studies have examined how the perceived quality of multiple interpersonal relationships is related to eating disorder (ED) symptom severity in adolescents and how psychological variables might influence these associations. The aim of this study is to determine whether the perceived level of trust, communication, and alienation in the relationship with one's mother, father, and peers are predictive of ED severity in adolescent females and to test the mediating effects of low self-esteem and negative mood on these associations. Adolescent females aged 12 to 18 (N = 186) with a diagnosis of Anorexia Nervosa (Restrictive; AN-R or Binge/Purge; AN-B/P) completed self-report measures evaluating the perceived quality of interpersonal relationships, ED symptom severity, low self-esteem, and negative mood. Multiple regressions revealed that the level of perceived alienation in the relationship with one's mother and peers was positively associated with ED symptom severity. Low self-esteem and negative mood acted as mediators of these associations. Considering that a high level of perceived alienation in the relationship with one's mother and peers appears to be associated with more severe ED symptoms through its impact on self-esteem and mood, improvements in the quality of these interactions are likely to be an effective target of intervention among adolescents.

Background: This study aimed to document recovery trajectories among adolescents with anorexia nervosa (AN) based on three markers of remission, namely changes in body weight, food restriction, and excessive exercise, and to identify predictors of these trajectories. Methods: One hundred twenty-six adolescent girls (14.7 ± 1.3 years) were recruited during initial assessment visits at specialized eating disorder (ED) programs in five University Health Centers across the province of Quebec, Canada. z-BMI and AN symptom severity (food restriction and excessive exercise) were assessed at initial assessment visits and subsequently reassessed at each quarterly follow-up over a 12-month period to identify recovery trajectories. Results: Considering the three markers of remission, three distinct trajectories emerged: Group 1, rapid responders; Group 2, gradual responders; and Group 3, unstable responders. At initial visits, a difference between groups was found regarding the type of treatment (p = 0.01) and weight suppression (p = 0.02). Group 1 had a higher number of youths hospitalized than Group 2 and Group 3, and a greater weight suppression than Group 3. Furthermore, individuals with atypical AN were more likely to belong to Group 2 than to Group 1 and Group 3 (p < 0.0001). Conclusions: This study contributes to a better understanding of the heterogeneity of recovery trajectories in adolescent girls with AN.
RESUMEN
Cutaneous malignant melanoma has increased more than three-fold in the past 35 years. Because damage is cumulative, exposure to ultraviolet radiation early in life elevates a risk that is increased further as individuals use artificial sources of ultraviolet radiation. The full impact and scope of damage caused by year-round indoor tanning may take years to appreciate given the long latency period for most skin cancers. Teenagers are frequent visitors to tanning parlours, with girls being more frequent and sustained users. The tanning industry disputes the World Health Organization's and the International Agency for Research on Cancer's classification of their product as a Class 1 physical carcinogen. Tanning parlours have sought to establish and maintain a client-base among teenagers. Consequently, the Canadian Paediatric Society is joining other prominent health organizations in support of a ban on the use of commercial tanning facilities by Canadian children and youth younger than 18 years of age.
RESUMEN
Inadequate nutritional rehabilitation of severely malnourished adolescents with Anorexia Nervosa (AN) increases the risk of medical complications. There is no consensus on best practices for inpatient nutritional rehabilitation and medical stabilization for severe AN. This study aimed to elaborate an admission protocol for adolescents with severe AN based on a comprehensive narrative review of current evidence. A Pubmed search was conducted in July 2017 and updated in August 2020, using the keywords severe AN or eating disorders (ED), management guidelines and adolescent. Relevant references cited in these guidelines were retrieved. A secondary search was conducted using AN or ED and refeeding protocol, refeeding syndrome (RS), hypophosphatemia, hypoglycemia, cardiac monitoring or cardiac complications. Evidence obtained was used to develop the admission protocol. Selective blood tests were proposed during the first three days of nutritional rehabilitation. Higher initial caloric intake is supported by evidence. Continuous nasogastric tube feeding was proposed for patients with a BMI < 12 kg/m2. We monitor hypoglycemia for 72 h. Continuous cardiac monitoring for bradycardia <30 BPM and systematic phosphate supplementation should be considered. Developing protocols is necessary to improve standardization of care. We provide an example of an inpatient admission protocol for adolescents with severe AN.

BACKGROUND: Anorexia Nervosa (AN) is a highly prevalent disease in adolescents and young adults (AYAs). The quality of initial inpatient medical management in a patient with severe malnutrition due to AN is crucial to prevent further medical instability. This review aims to inventory evidence regarding initial refeeding and management of AYAs with AN in an inpatient setting, in order to avoid medical complications. METHODS: A systematic review will be conducted using PubMed, MEDLINE, All EBM Reviews, Embase, PsycINFO, Cochrane Database and CINAHL. The search strategy consists of terms related to anorexia, hospitalization and Pediatrics. Randomized controlled trials, case-control studies, cross-sectional and cohort studies will be included. Participants will include adolescents and adults 18-24 years old diagnosed with AN and meeting criteria for severe disease. The primary outcome will be any of the following complications: hypophosphatemia, refeeding syndrome, hypoglycemia, cardiac arrythmia, hepatic cytolysis or death. Data will be extracted and the risk of bias will be assessed by one author and reviewed by a second author. Results will be presented in a systematic narrative synthesis format. The quality of evidence for all outcomes will be evaluated using the GRADE methodology. DISCUSSION: This systematic review will examine current evidence on initial inpatient refeeding and help to document effectiveness of initial inpatient management in AYAs with severe AN in avoiding further medical complications. TRIAL REGISTRATION: This study is registered on PROSPERO under the reference number CRD42019123608 .
RESUMEN
Importance: The COVID-19 pandemic has had considerable mental health consequences for children and adolescents, including the exacerbation of previously diagnosed eating disorders. Whether the pandemic is a factor associated with the concomitant increase in new-onset anorexia nervosa or atypical anorexia nervosa remains unknown. Objective: To assess the incidence and severity of newly diagnosed anorexia nervosa or atypical anorexia nervosa in a national sample of youth before and during the first wave of the COVID-19 pandemic. Design, Setting, and Participants: This repeated cross-sectional study analyzed new eating disorder assessments that were conducted at 6 pediatric tertiary-care hospitals in Canada between January 1, 2015, and November 30, 2020. Patients aged 9 to 18 years with a new anorexia nervosa or atypical anorexia nervosa diagnosis at the index assessment were included. Exposures: COVID-19-associated public health confinement measures during the first wave of the pandemic (March 1 to November 30, 2020). Main Outcomes and Measures: Primary outcomes were the incidence and hospitalization rates within 7 days of de novo anorexia nervosa or atypical anorexia nervosa diagnosis. Event rate trends during the first wave were compared with trends in the 5-year prepandemic period (January 1, 2015, to February 28, 2020) using an interrupted time series with linear regression models. Demographic and clinical variables were compared using a χ2 test for categorical data and t tests for continuous data. Results: Overall, 1883 children and adolescents with newly diagnosed anorexia nervosa or atypical anorexia nervosa (median [IQR] age, 15.9 [13.8-16.9] years; 1713 female patients [91.0%]) were included. Prepandemic anorexia nervosa or atypical anorexia nervosa diagnoses were stable over time (mean [SD], 24.5 [1.6] cases per month; ß coefficient, 0.043; P = .33). New diagnoses increased during the first wave of the pandemic to a mean (SD) of 40.6 (20.1) cases per month with a steep upward trend (ß coefficient, 5.97; P < .001). Similarly, hospitalizations for newly diagnosed patients increased from a mean (SD) of 7.5 (2.8) to 20.0 (9.8) cases per month, with a significant increase in linear trend (ß coefficient, -0.008 vs 3.23; P < .001). These trends were more pronounced in Canadian provinces with higher rates of COVID-19 infections. Markers of disease severity were worse among patients who were diagnosed during the first wave rather than before the pandemic, including more rapid progression (mean [SD], 7.0 [4.2] months vs 9.8 [7.4] months; P < .001), greater mean (SD) weight loss (19.2% [9.4%] vs 17.5% [9.6%]; P = .01), and more profound bradycardia (mean [SD] heart rate, 57 [15.8] beats per minute vs 63 [15.9] beats per minute; P < .001). Conclusions and Relevance: This cross-sectional study found a higher number of new diagnoses of and hospitalizations for anorexia nervosa or atypical anorexia nervosa in children and adolescents during the first wave of the COVID-19 pandemic in Canada. Research is needed to better understand the drivers and prognosis for these patients and to prepare for their mental health needs in the event of future pandemics or prolonged social isolation.

AIM: Serum creatinine level is the most used test to evaluate renal function in patients with anorexia nervosa (AN). We investigated which formula of glomerular filtration rate (GFR) based on simple blood sample had the best correlation with the gold standard in malnourished adolescent patients with AN. METHODS: A prospective study was conducted on 34 adolescents hospitalized for the restrictive type of AN between 2014 and 2017. The GFR was measured by isotopic technique and calculated using the Cockroft-Gault, Schwartz equations and 3 other formula. RESULTS: For the 34 AN patients, mean BMI -2.7 zscore, the mean measured GFR was 107+/-26 mL/min/1.73 m2. Among them, 35% (12/34) had a GFR under 90 mL/min/1.73 m2. The calculated GFR with Cockroft-Gault formula had the best correlation with the measured GFR (R2 = 0.852), whatever the creatinine level. No correlation was found between creatinine level and measured GFR. CONCLUSION: Kidney dysfunction is common in malnourished AN adolescents, so clinicians should always evaluate AN patients for renal impairments. Creatinine level is a poor indicator of renal function in this population. The most accurate formula to test GFR with a simple blood test is the Cockroft-Gault formula.

STUDY OBJECTIVE: Estrogens are suspected to have a negative effect on pulmonary function in women with cystic fibrosis (CF). The aim of our study was to investigate, in a CF adolescent population, the effect of hormonal contraception (HC) on lung function by assessing the forced expiratory volume in 1 second (FEV1), the number of exacerbations of pulmonary condition, and antibiotic use. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We conducted a cohort retrospective chart review of girls from age 13 to 18 years old who were followed in the CF clinic of a university hospital center. Wilcoxon rank sum test with continuity correction, 2-sample t test, conditional test of Poisson rates, and χ2 test were conducted to identify differences in results between adolescents with or without use of HC for the following outcomes: FEV1, use of antibiotics by nebulizer, and hospital admission for exacerbations of pulmonary condition. RESULTS: Among 127 adolescents, 64/127 (50.4%) took HC; 12/127 (9%) continuously had been taking HC over 3 years. For girls taking HC for more than 3 years, FEV1 at 18 years old was significantly higher than for girls who had never taken HC (85.17% vs 71.05%; P = .043). However, there was no difference in the number of hospital admissions for exacerbation of pulmonary condition between these 2 groups (P = .057). There was no difference between HC vs non-HC users in the percent of patients taking antibiotics by nebulizer over the 6 years of follow-up. CONCLUSION: Our study suggests that in adolescents with CF, HC has no deleterious effects on the FEV1. Further prospective studies could be done to confirm these results.

Health care professionals must be alert to the high prevalence of low adherence to treatment during adolescence. Low adherence increases morbidity and medical complications, contributes to poorer quality of life and an overuse of the health care system. Many different factors have an impact on adherence. However, critical factors to consider in teens are their developmental stage and challenges, emotional issues and family dysfunction. Direct and indirect methods have been described to assess adherence. Eliciting an adherence history is the most useful way for clinicians to evaluate adherence, and could be the beginning of a constructive dialogue with the adolescent. Interventions to improve adherence are multiple - managing mental health issues appropriately, building a strong relationship, customizing the treatment regimen if possible, empowering the adolescent to deal with adherence issues, providing information, ensuring family and peer support, and motivational enhancement therapy. Evaluation of adherence at regular intervals should be an important aspect of health care for adolescents.
