Comparison between continued inpatient treatment versus day patient treatment after short inpatient care in early onset anorexia nervosa (COTIDEA trial): a study protocol for a non-inferiority randomised controlled trial.

BACKGROUND: In children with early-onset anorexia nervosa (first symptoms before 13 years old, EO-AN), experts recommend initial outpatient treatment but in-patient treatment (IP) is frequently indicated due to acute medical instability or for those who have not improved with outpatient treatment. This IP can target either a partial weight restauration or a total weight normalization (return to the previous BMI growth trajectory). There are no evidence in the literature on which is the better therapeutic option in EOAN. But as long length of stay induce social isolation, with elevated costs, we wonder if a stepped-care model of daypatient treatment (DP) after short IP stabilisation may be a treatment option as effective as full-time IP to target weight normalization. We designed a two-arm randomised controlled trial testing the non-inferiority of a stepped-care model of DP after short IP stabilisation versus full-time IP. METHODS: Eighty-eight children aged 8 to 13 years suffering from EOAN with initial severe undernutrition will be randomly allocated to either IP treatment as usual or a stepped care DP model both targeting weight normalization. Assessments will be conducted at inclusion, somatic stabilization, weight normalization, 6 months and 12 months post randomisation. The primary outcome will be BMI at 12 months post-randomisation. Secondaries outcomes will included clinical (tanner stage), biological (prealbumin, leptin, total ghrelin and IGF1) and radiological (bone mineralization and maturation) outcomes, eating symptomatology and psychiatric assessments, motivation to change, treatment acceptability and quality of life assessments, cost-utility and cost-effectiveness analyses. DISCUSSION: COTIDEA will provide rigorous evaluation of treatment alternative to full-time inpatient treatment to allow a reduction of social iatrogenic link to hospital length of stay and associated costs. TRIAL REGISTRATION: Trial is registered on ClinicalTrials.gov (NCT04479683).

Inpatient target discharge weight for early-onset anorexia nervosa: Restoring premorbid BMI percentile to improve height prognosis.

OBJECTIVE: Early-onset anorexia nervosa (EO-AN) is characterized by restricted food intake leading to low body weight, emerging before 14 years old. Most patients reaching a target body mass index (BMI) around the 25th percentile at hospitalization discharge display an incomplete prospective height catch-up. A better understanding of height prognosis determinants is required. METHODS: In 74 children with an EO-AN, we collected height and weight premorbidly, at hospitalization, and at discharge, 6 months, 12 months, and at longer-term follow-up of 36 months. We defined a height prognosis parameter (HPP) as the difference between the height percentile at follow-up times and the premorbid height percentile. We explored the relationship between weight parameters and height catch-up at follow-up with linear regression analyses. RESULTS: A higher weight suppression (WS) - i.e., difference between premorbid and current BMI - at admission and discharge was associated with lower HPP - i.e., a greater loss of height - at 12 months and 36 months follow-up. Similarly, a higher premorbid BMI percentile was associated with a lower HPP at 12 and 36 months. CONCLUSION: Target discharge weight for EO-AN patients should be tailored and based on premorbid BMI trajectory to improve height prognosis.

MANAGEMENT OF ENDOCRINE DISEASE: Approach to the management of children and adolescents with Gender Dysphoria.

Over the past 20 years, the care for transgender adolescents has developed throughout many countries following the "Dutch Approach" initiated in the 90's in pioneer countries as the Netherlands, United States and Canada, with increasing numbers of children and adolescents seeking care in transgender clinics. This medical approach has considerable positive impacts on the psychological outcomes of these adolescents and several studies have been recently published underlining the relative safety of such treatments. This paper reviews the current standards of care for transgender children and adolescents with particular emphasis on disparities among countries and short to medium-term outcomes. Finally it highlights ethical considerations regarding categorization of gender dysphoria, timing of treatment initiation, infertility, and how to deal with the long-term consequences.

Gender dysphoria, originally called gender identity disorder, is characterized by the dissociation between one's expressed gender and the gender of rearing as assigned at birth, which generates significant clinical distress and social, academic, and other important forms of isolation. This state is also known as transgender or transsexualism and is recognized as a medical disease. Adults with gender dysphoria can benefit from psychological, medical, and surgical care. However, gender dysphoria rarely occurs in adulthood but rather emerges in childhood or adolescence, generating deep social and academic difficulties, especially at puberty. For the last 10years, the management of gender dysphoria in children and adolescents has developed in several countries, specifically in Europe, but remains under-recognized in France. Since 2013, several pediatric psychiatry and endocrinology departments have initiated a multidisciplinary evaluation and management approach for these patients. This article reviews the clinical criteria helping diagnose gender dysphoria and presents the different steps in the assessment and management of these patients in accordance with international guidelines.

[Brain imaging in early onset anorexia]. / Données d'imagerie cérébrale dans l'anorexie mentale à début précoce.

Structural and functional brain alterations in the structures involved in taste processing, emotions regulation and the reward system have been described in anorexia nervosa. The neurodevelopmental origin of this disorder has been recently discussed. In this article, brain-imaging data in early onset anorexia nervosa will be recalled and the relationship between clinical symptoms, normal brain maturation and brain imaging data in adolescents and adults will be discussed.

[Cognitive remediation therapy for children and adolescents with anorexia nervosa in France: an exploratory study]. / Évaluation d'un programme de remédiation cognitive au sein d'un groupe d'enfants et d'adolescents anorexiques français: étude exploratoire.

OBJECTIVE: Cognitive remediation therapy (CRT) seems to be increasingly interesting in the treatment of anorexia nervosa for adult patients. We attempted to apply this support to a group of young inpatients, initially to assess its feasibility and acceptability, and then to improve its content for therapeutic application and future research. METHODS: Ten 12- to 17-year-old inpatients with primary DSM-IV diagnosis of anorexia nervosa participated in a 10-week intervention program with a one-hour group session of CRT per week. All 10 patients were assessed before the intervention and those who completed the 10 sessions were assessed after. Assessment included a clinical examination by a psychiatrist, a battery of clinical inventories, and set-shifting tests. Moreover, each patient wrote a letter providing feedback on the intervention for subsequent analysis. RESULTS: Only two patients completed all 10 sessions, the other eight who were discharged from the hospital in the meantime could not attend the sessions for practical reasons. After the 10 sessions, an improvement in BMI and in measured levels of some psychopathological symptoms was observed in our two patients. Most neuropsychological task performances were improved after cognitive remediation. Feedback from the 10 patients was generally positive. CONCLUSION AND IMPLICATIONS FOR PRACTICE: This preliminary investigation suggests that cognitive remediation therapy is acceptable and feasible in this population. Replication of these findings requires a larger sample, improvement of the trial design, more sensitive measures, and another training format to avoid loss of so many participants.

Social cognition and the superior temporal sulcus: implications in autism.

The most common clinical sign of autism spectrum disorders (ASD) is social interaction impairment, which is associated with communication deficits and stereotyped behaviors. Based on brain-imaging results, our hypothesis is that abnormalities in the superior temporal sulcus (STS) are highly implicated in ASD. These abnormalities are characterized by decreased grey matter concentration, rest hypoperfusion and abnormal activation during social tasks. STS anatomofunctional anomalies occurring early across brain development could constitute the first step in the cascade of neural dysfunctions underlying autism. It is known that STS is highly implicated on social perception processing, from perception of biological movements, such as body movements or eye gaze, to more complex social cognition processes. Among the impairments that can be described in social perception processing, eye gaze perception is particularly relevant in autism. Gaze abnormalities can now be objectively measured using eye-tracking methodology. In the present work, we will review recent data on STS contributions to normal social cognition and its implication in autism, with particular focus on eye gaze perception.

[Brain imaging of infantile autism]. / Imagerie cérébrale dans l'autisme infantile.

Understanding of brain structural anomalies seen in children with autism has considerably progressed since the apparition of MRI and functional imaging. All the results are converging toward the description of anatomical and functional anomalies in the regions of the so-called "social brain". Statistical analyses show diminution of gray matter in the region of the superior temporal sulcus (STS). Functional studies with PET shows a diminution of brain blood flow at rest in the same region. Brain activation studies show absence of activation of the specialized region in processing human voice and hypoactivation of "social brain" regions in complex tasks of social cognition. At last, abnormal connectivity between the frontal and temporal regions has been showed. Those regions are implicated in processing sensorial inputs necessary for normal social life. All those anomalies could be responsible of the abnormal social behaviour pattern of children with autism.

Fertility awareness in women attending a fertility clinic.

Eighty women attending for consultation at a tertiary referral fertility unit over a 3-month period were surveyed for their knowledge of fertility awareness and how they used this information to enhance their chances of conception. It was hypothesized that less than 50% of the subjects had an adequate understanding of when the fertile time occurred in their menstrual cycle. A questionnaire was completed anonymously by each subject and these were scored in 3 categories for fertility awareness by 2 independent Natural Family Planning teachers. Scores ranged from 0 for women who had no concept of fertility awareness, to 6 for women who were highly aware. The results showed that 26% (N = 21) of subjects had a score of 4 or greater which was considered as having an adequate understanding. The hypothesis was accepted, giving reason for concern about the effectiveness of consumer education at all levels of fertility investigation.

PIP: Fertility awareness was assessed in a survey of 80 women presenting over a 3-month period to a tertiary referral unit at the National Women's Hospital in Auckland, New Zealand, for infertility investigation. It was hypothesized that less than 50% of menstruating women with a history of at least 2 years of infertility have an adequate understanding about the fertile time of their menstrual cycle. 60% of women had been trying to conceive for 2-3 years, 23% for 4-5 years, and 17% for more than 6 years. For 58% of clients, this was their first visit to a fertility clinic. 13% had attended a natural family planning (NFP) clinic previously. On the basis of questionnaire responses, participants were graded from 0 to 2 in each of the following 3 categories: 1) level of fertility symptom awareness (cervical mucus and ovulatory pain), 2) level of understanding of what these symptoms mean, and 3) level of use of this information to enhance conception. Only 21 women (26%) had a final score of 4 or greater--a predetermined cut-off considered indicative of adequate fertility awareness. The largest percentage of women (46%) had scores of 0-1. 80% of women with previous NFP instruction had adequate fertility awareness scores. These finding supported the study hypothesis of a generally poor level of fertility awareness among women presenting for treatment of infertility. Greater utilization of NFP clinics by general practitioners and specialists, as well as incorporation of NFP trained nurses into tertiary referral clinics, are recommended.
