Few weight management interventions target young children with obesity from low-income minority families. To conduct a nonrandomized, pragmatic, pilot study of an adapted, evidence-based, weight management program (Kids N Fitness [KNF]) customized for children ages 3-7 years (Kids N Fitness Jr. [KNF-JR]) on changes in adiposity, nutrition, and physical activity behaviors.

This study examines how baseline demographics, psychosocial characteristics, and intervention delivery predict engagement among adolescents with overweight and obesity seeking treatment. Data originates from a multisite randomized control trial evaluating the efficacy of an app-based weight loss intervention, compared with standard in-clinic model in adolescents with overweight and obesity. Participants were randomized to one of the three arms: (1) AppCoach, (2) AppAlone, or (3) Control.

Background: Time limited eating (TLE) has been shown to be effective for weight loss and improvement of glycemic control in adults with obesity and type 2 diabetes (T2D), but has not been well studied in adolescents. TLE may be a more feasible, flexible and effective dietary intervention for adolescents because it removes the need for intensive counting of calories or macronutrients, and emphasizes eating during a specified time period.

Objectives: The aim of this study is to assess the feasibility of a TLE approach in adolescents with obesity using a continuous glucose monitor (CGM) to promote adherence to the intervention.

Background: Optic nerve hypoplasia (ONH), a leading cause of pediatric blindness, is associated with brain malformations and hypopituitarism in the constellation known as septo-optic dysplasia. Neuroimaging is used to anticipate hypopituitarism, but with unconfirmed reliability. We report prospective findings on the association of hypopituitarism with brain malformations.

Purpose: As part of a long-term, prospective study of prenatal and clinical risk factors for optic nerve hypoplasia (ONH) at Children's Hospital Los Angeles, pattern ERGs (PERGs) were evaluated for prognostic value using an automated objective and robust analytical method.

Methods: Participants were 33 children with ophthalmoscopically diagnosed ONH [disc diameter-to-disc macula ratio (DD/DM) less than 0.35 in one or both eyes on fundus photographs].

Background: Hypopituitarism and obesity are causes of major lifelong morbidity in patients with optic nerve hypoplasia (ONH). Growth hormone deficiency (GHD) affects the majority of children with ONH, though the degree of deficiency and variability of early growth patterns range from early severe retardation to normal initial growth. The utility of early GH replacement for improving anthropometric, body composition, and lipid outcomes in patients with ONH and GHD, especially those with normal initial height velocity, is unknown.

Purpose: Pattern electroretinograms (PERGs) have inherently low signal-to-noise ratios and can be difficult to detect when degraded by pathology or noise. We compare an objective system for automated PERG analysis with expert human interpretation in children with optic nerve hypoplasia (ONH) with PERGs ranging from clear to undetectable.

Methods: PERGs were recorded uniocularly with chloral hydrate sedation in children with ONH (aged 3.

This report describes gelastic seizures in patients with optic nerve hypoplasia and hypothalamic dysfunction without hypothalamic hamartoma. All participants (n = 4) from the optic nerve hypoplasia registry study at Children's Hospital Los Angeles presenting with gelastic seizures were included. The clinical and pathology characteristics include hypothalamic dysgenesis and dysfunction, but no hamartomas.

Purpose: To evaluate the effectiveness of stem cell therapy in improving visual acuity or optic nerve function in children with optic nerve hypoplasia (ONH).

Methods: Subjects with ONH aged 7-17 years who voluntarily elected to undergo stem cell therapy in China were matched with controls on age, visual acuity, and communication level. Visual acuity, optic nerve size, and sensitivity to light were assessed before stem cell therapy and twice after.

Aim: This study examined the utility of standard autism diagnostic measures in nine children (aged 5-9y) with severe vision impairment and a range of social and language functioning.

Method: The Autism Diagnostic Observation Schedule (ADOS) and the Autism Diagnostic Interview, Revised (ADI-R) were systematically modified and used to assess symptoms of autism in children with vision less than or equal to 20/800, the majority of whom had optic nerve hypoplasia. The results of the assessments, including analysis of symptom patterns, were compared with expert autism diagnoses.

Purpose: To assess in children with optic nerve hypoplasia (ONH) whether newborn screening (NBS) thyroid-stimulating hormone (TSH) measurements can detect central hypothyroidism and whether newborn TSH or subsequent thyroidal status is associated with visual function.

Methods: From a registry of children with ONH at Children's Hospital Los Angeles, post-natal thyroidal status was retrospectively compared with NBS TSH levels in the subset of subjects born in California. The subset of subjects with outcome data at age 5 years was assessed for relationship of vision to NBS TSH levels and ultimate thyroidal status.

Background/aims: The majority of children with optic nerve hypoplasia (ONH) develop hypopituitarism and many also become obese. These associated conditions are a major cause of morbidity and are possibly due to hypothalamic dysfunction. Because mild hyperprolactinemia often occurs in subjects with disorders of the hypothalamus, we examined whether hyperprolactinemia was present in children with ONH during the first 3 years of life and whether it was a marker for hypopituitarism and/or obesity.

Background: Optic nerve hypoplasia (ONH) with/or without septo-optic dysplasia (SOD) is a known concomitant of congenital growth hormone deficiency (CGHD).

Methods: Demographic and longitudinal data from KIGS, the Pfizer International Growth Database, were compared between 395 subjects with ONH/SOD and CGHD and 158 controls with CGHD without midline pathology.

Results: ONH/SOD subjects had higher birth length/weight, and mid-parental height SDS.

Background: Children with optic nerve hypoplasia (ONH) are at high risk for early-onset congenital central hypothyroidism (CH); however, reports of evolving, late-onset CH are rare and poorly documented.

Aim: To examine the clinical and biochemical data of children with ONH who developed CH after documented normal thyroid function tests at an earlier age.

Patients And Methods: Children who developed late-onset CH were selected for review from an observational study (n = 214) that examined clinical risk factors for endocrinological abnormalities in children with ONH.

The purpose of the study is to characterise retinal function using light-adapted electroretinograms (ERGs) in a series of young children with ONH, congenital dysplasia of retinal ganglion cells. ERGs were recorded with chloral hydrate sedation in 27 children with ONH (18 with bilateral and 9 with unilateral ONH, age 4-35 months) and an adult reference population (n = 12). Stimuli included ISCEV standard flash, oscillatory potentials (OPs) and standard flicker as well as a light-adapted luminance-response series (photopic hill).

Background: Developmental delay has been reported to occur with optic nerve hypoplasia, a leading cause of pediatric blindness, but has not been systematically examined for its prevalence and correlation with associated pathologies of optic nerve hypoplasia.

Objective: The purpose of this study was to determine the developmental outcomes of children with optic nerve hypoplasia and the correlation of development with neuroradiographic, endocrinologic, and ophthalmic findings.

Methods: We conducted a prospective analysis of 73 subjects diagnosed with optic nerve hypoplasia at <36 months of age for developmental outcomes at 5 years of age.
