Curve matching to predict future growth in patients receiving recombinant human growth hormone: an interpretable and explainable method using big data

van Dommelen Paula , Arnaud Lilian , Koledova Ekaterina

Background: Prediction models demonstrate potential in predicting growth in patients receiving recombinant human growth hormone (r-hGH) for growth disorders. However, considerable information from patients is needed to calculate a predicted growth curve. The curve matching technique only requires height data. This technique identifies growth curves that are similar (matched) among real-world patients within a database. The growth curves of these ‘matched...

Real-World Data From Electronic Monitoring of Adherence to Growth Hormone Treatment in Children with Growth Disorders: A Descriptive Analysis

Koledova Ekaterina , Tornincasa Vincenzo , van Dommelen Paula

Poor adherence to long-term growth hormone (GH) treatment can lead to suboptimal clinical outcomes. The easypod™ connect eHealth platform enables healthcare professionals to obtain an accurate picture of real-world adherence by allowing patients to transmit adherence data to a database. Our aims were to assess adherence to r-hGH (Saizen, Merck KGaA, Darmstadt, Germany) treatment with the easypod connect platform in children from treatment start to 48 months and to investi...

Follow-up to Adulthood of Two 46,XY Siblings with 5-alpha Reductase Deficiency and Different Sex of Rearing

Chiniara Lyne , Sandberg David , Van Vliet Guy

Background: 46,XY patients with 5α-reductase deficiency (5-ARD), reared from birth as girls, are reported to self-reassign as boys subsequent to a masculinizing puberty; whether this holds true in cases of early orchidectomy is less well documented.Objective and hypotheses: Prepubertal orchidectomy reduces the likelihood of gender self-reassignment.Method: Presentation, management and outcome of two siblings with 5-ARD with na...

Characteristics of a Population of Obese Children and Adolescents: Suggesting a New Paradigm

Van Meter Quentin , Welstead Bethany , Low Joey

Background: Obese children come from families where either one or both parents are obese, suggesting obesity is the result of exposure to detrimental environment.Objective and hypotheses: We propose that inherited insulin resistance is the core which promotes development of obesity and that allergic airway obstruction stalls development of obesity, while peptic gastritis promotes over-eating by confounding portion control.Method: W...

Impact of the COVID-19 pandemic and related lockdown measures on lifestyle behaviours and quality of life in children and adolescents with severe obesity

Welling MS , Abawi O , van den Eynde E , van Rossum EFC , Halberstadt J , Brandsma AE , Kleinendorst L , van den Akker ELT , van der Voorn B ,

Introduction: Lockdown measures following the COVID-19 pandemic are shown to have greatly affected lifestyle behaviours and health-related quality of life (HRQoL) of children. The impact on children with severe obesity has not yet been described. Aim of this study was to investigate the impact of COVID-19 lockdown on eating behaviours, physical activity (PA), screen time, and HRQoL of children (including adolescents) with severe obesity....

Pathogenic variants in GHSR cause short stature and growth hormone neurosecretory dysfunction; results from a large case series

Introduction: Ghrelin binds to its receptor GHSR1A, encoded by GHSR, on somatotrophs of the pituitary. Growth hormone (GH) secretion is enhanced by ghrelin binding as well as the receptor’s constitutive activity. Results from in vitro experiments, knock-out mice, and GWAS suggest that heterozygous loss-of-function of GHSR may be associated with short stature, but observations in case studies are equivocal. We aimed to better ch...

Pten knockout in osteoprogenitor cells leads to loss of adipose tissue

Kolbig Florentien , Lorenz Judith , Roth Lisa , Lindhorst Andreas , Thor Doreen , Le Duc Diana , Gericke Martin , Kiess Wieland , Klöting Nora , Krause Kerstin , Garten Antje

Background and Aim: Pediatric patients with germline mutations in the phosphatase and tensin homolog (Pten) gene frequently develop aberrant adipose tissue growth called lipomas. In severe cases, recurrent lipoma formation can have adverse effects on organ function and quality of life. Due to the lack of understanding the basis of lipoma development, no systemic treatment options are available. We therefore aimed to characterize an already described lipoma bea...

Conditional PTEN knockout in mouse osteoprogenitor cells impacts bone structure and turnover

Lorenz Judith , Kirstein Anna , Nebe Michѐle , Richter Sandy , LeDuc Diana , Kiess Wieland , Klöting-Blüher Nora , Baschant Ulrike , Garten Antje

Background: Bone development and remodeling are controlled by the phosphoinositid-3-kinase (PI3K) signaling pathway. We investigated the effects of downregulation of phosphatase and tensin homolog (Pten), a negative regulator of PI3K signaling, in osteoprogenitor cells.Methods: Femura, tibiae and bone marrow stromal cells (BMSCs) from mice with Cre-inducible Pten knockdown in cells expressing the transcription factor Ost...

Aims: Do-It-Yourself Artificial Pancreas Systems (DIYAPS) represent a unique patient-initiated treatment in which commercially available and approved medical devices such as continuous glucose monitoring systems (CGMs) and insulin pumps are connected by an off-label algorithm, and are remotely controlled by open-source algorithms to automate insulin delivery. While these systems are co-created by the DIYAPS community, and access is open to everyone, users have...

Neonatal Overfeeding Alters Hepatic Insulin Sensitivity During Lactation and Leads to Long-term Insulin Resistance and Fatty Liver in Mice: Key Role of Mogat1

Ramon-Krauel Marta , Pentinat Thais , Cebria Judith , Vila Maria , Perez-Wienese Ricky , Kalko Susana , Tietge Uwe , Plosch Torsten , Diaz Ruben , Jimenez-Chillaron Josep

Background: Excessive energy intake and rapid weight gain early in life are associated with obesity, type 2 diabetes, hepatic steatosis and other features of the metabolic syndrome. The monoacylglycerol acyltransferase (MGAT) is an enzyme involved in an alternative pathway for triglyceride (TAG) synthesis and storage. It has been recently proposed to have potential implications in the pathogenesis of hepatic insulin resistance (IR).Objective: To understa...
