Background: This study aimed to determine the psychometric properties of the Compulsive Exercise Test (CET) among an adult sample of patients with eating disorders.
Method: Three hundred and fifty six patients and 360 non-clinical control women completed the CET and the Eating Disorders Examination questionnaire (EDE-Q).
Results: A confirmatory factor analysis revealed that the clinical data showed a moderate fit to the previously published five factor model derived from a community sample (Taranis L, Touyz S, Meyer C, Eur Eat Disord Rev 19:256-268, 2011). The clinical group scored significantly higher than the non-clinical group on four of the five CET subscales, and logistic regression analysis revealed that the CET could successfully discriminate between the two groups. A Receiver Operating Curve analysis revealed that a cut-off score of 15 on the CET resulted in acceptable values of both sensitivity and specificity.
Conclusions: The CET appears to have a factor structure that is acceptable for use with an adult sample of patients with eating disorders. It can identify compulsive exercise among patients with eating disorders and a cut-off score of 15 is acceptable as indicating an appropriate cut-off point.

Lessons learned from 5 years of pegvaliase in US clinics: A case series.
Mol Genet Metab Rep

Hayward Genetics Center, Dept of Pediatrics, Tulane University Medical School, New Orleans, LA, USA.
Objective: To provide insights and strategies for pegvaliase management in challenging cases with phenylketonuria (PKU) based on the first 5 years of experience with pegvaliase in real-world clinical practice.
Methods: Twelve PKU experts gathered during a one-day, in-person meeting to discuss clinical cases illustrating important lessons from their experiences treating patients with pegvaliase in real-world clinical practice. Challenges with pegvaliase experienced prior to and during treatment and corresponding strategies to overcome them were discussed.

Background: Pica is an eating disorder in which a person feels the urge to eat non-nutritious, non-food substances. It can occur at any age; however, a higher prevalence is observed among children with mental health issues and pregnant women. Recently, additional attention has been given to the role of sensory sensitivity in eating disorders.

Introduction: Regulatory problems of eating, sleeping, and crying in infancy may index mental health vulnerability in older ages, and knowledge is needed to inform strategies to break the developmental trajectories of dysregulation in early childhood. In this study, we examined the prospective associations between infant regulatory problems at the age of 8-10 months identified by community health nurses (CHN) and mental disorders diagnosed in hospital settings in children aged 1-8 years.
Methods: From a cohort of all newborn children in 15 municipalities in the Capital Region of Copenhagen ( = 43,922) we included all children who were examined by CHNs at the scheduled home visit at the age of 8-10 months ( = 36,338).

This is a study of avoidant/restrictive food intake disorder (ARFID), other feeding disorders, and background factors, including seventy-two children (thirty-one girls, forty-one boys, aged 4-178 months) referred to a secondary/tertiary feeding service for eating difficulties and/or compromised growth. An in-depth review of their medical records was performed. Diagnostic criteria for ARFID were met in 26% of cases.

Objective: The aim of our study was to delineate the differences in demographics, comorbidities, and hospital outcomes by eating disorder types in adolescents and transitional-age youth (15-26 years), and measure the association with psychiatric comorbidities.
Methods: We conducted a cross-sectional study using the nationwide inpatient sample (2018-2019) and included 7,435 inpatients (age 12-24 years) with a primary diagnosis of eating disorders: anorexia nervosa (AN, 71.7%), bulimia nervosa (BN, 4.
