Background: In 2020, the average glycaemic index of Type 1 diabetes (T1D) in Southeast Asia (SEA) countries were reported to be at around 83mmol/mol. In many low-middle-income countries (LMICs) in SEA, insufficient infrastructure, lack of universal health coverage and professional knowledge are factors that affect T1D outcomes that adversely affect mortality and morbidity. Action4diabetes (A4D) currently provides comprehensive partnership programmes with defin...

Exome sequencing reveals a high proportion of causal and candidate gene variants in a large early-onset Primary Ovarian Insufficiency cohort

M McGlacken-Byrne Sinead , P Suntharalingham Jenifer , Ishida Miho , Buonocore Federica , Del Valle Ignacio , Cameron-Pimblett Antoinette , Genomics UCL , T Dattani Mehul , S Conway Gerard , C Achermann John

Background: The presentation of early-onset Primary Ovarian Insufficiency (EO-POI), most often with primary amenorrhea, is at one end of a spectrum spanning 40 years. The aetiology of POI is frequently unclear but next generation sequencing of varied age groups has identified several associated genetic variants. Whether girls with EO-POI are more likely to have a genetic aetiology than those with later presentations remains unknown.<stro...

Global recall of a growth hormone jet delivered device: experiences with children forced to switch from a needle free system to a growth hormone device with needle.

P. van Eck Judith , S. Renes Judith , J.C. Sas Theo , L.T. van den Akker Erica , C.M. van der Kaay Daniëlle

Introduction: Growth hormone (GH) treatment is essential for growth in children with GH deficiency. Also short children born small for gestational age (SGA), and children with syndromes like Turner Syndrome (TS), Noonan Syndrome (NS) and Silver Russel Syndrome (SRS) can benefit from GH treatment. For children with needle anxiety GH delivered by a jet device can be a solution for the daily subcutaneous treatment for many years. In 2021, a global recall of the o...

LGR4-Wnt β-Catenin Signalling Directs GnRH Network Development, with Defects Leading to Self-Limited Delayed Puberty

Mancini Alessandra , Howard Sasha R. , Cabrera Claudia P. , Barnes Michael R. , David Alessia , Wehkalampi Karoliina , Vassart Gilbert , Cariboni Anna , Garcia Marie Isabelle , Guasti Leonardo , Dunkel Leo

Background: The initiation of puberty is dependent upon an augmentation of gonadotropin-releasing hormone (GnRH) secretion from the hypothalamus. Development of the GnRH neuroendocrine network in embryonic life depends on coordinated migration of neurons from the vomeronasal organ in the nose to the forebrain. We have previously demonstrated that dysregulation in GnRH neuronal migration leads to delayed pubertal onset. Late puberty affects up to 2% of the ...

Introduction: The human fecal microbiota is known to shift in composition during adolescence, but whether fecal microbiota is associated with timing of sexual maturation is unknown. In mice, the change in the composition of fecal microbiota during puberty appears to be sex-specific and associate with changes in testosterone. We investigated the association between intestinal microbiota and pubertal timing in adolescents.Subjects ...

Differences Between Short- and Long-term Outcomes of Laparoscopic Sleeve Gastrectomy in Adolescence

Ybarra Marina , Rocha Franco Ruth , Santos Tiago Jerônimo dos , Rachid Ludmilla , Bezerra Marilia P. C. , Cominato Louise , Damiani Durval , Prieto Velhote Manoel Carlos

Background: Laparoscopic sleeve gastrectomy (LSG) has been established as a safe and effective bariatric procedure during adolescence, but its long-term results remain uncertain. Our aim was to report and compare the short- and long-term outcomes of LSG in adolescents.Methods: We performed a retrospective analysis of patients submitted to LSG between 2010 and 2013 in our Institution. Baseline, short-term (1 year) and lon...

RNPC3 Mutations Associate Prolactin Deficiency and Ovarian Insufficiency, Expanding the Phenotype Beyond Isolated Growth Hormone Deficiency Type V (MIM#618860)

Martos-Moreno Gabriel Á. , Travieso-Suárez Lourdes , Pozo Jesús , Chowen Julie , Pérez-Jurado Luis A. , Argente Jesús

Background: The first three children reported to have biallelic mutations in RNPC3 presented with growth hormone (GH) deficiency and pituitary hypoplasia (MIM#618860). RNPC3 codes for a minor spliceosome protein required for U11/U12 small nuclear ribonucleoprotein formation and splicing of U12-type introns. The underlying mechanism causing GH deficiency in these patients is not fully understood. Moreover, whether the association of further ho...

References for Testicular Volume Measured by Ultrasound and for Pubic Hair in 6-16 Year-Old Norwegian Boys

Oehme Ninnie B. , Roelants Mathieu , Bruserud Ingvild S. , Madsen André , Eide Geir Egil , Bjerknes Robert , Rosendahl Karen , Júlíusson Pétur B.

Objective: Recent studies have suggested earlier onset of pubertal development in boys. As assessment with orchidometer tends to overestimate true testicular volume (TV), and measurements based on ultrasound (US) have been proposed as a more reliable method, we present US based references in 6-16 year-old Norwegian boys. Our results are compared with data from Europe and the United States (U.S.) in order to establish evidence for an ongoing secular trend in ma...

Novel Pubertal References for Girls Using Ultrasound to Stage Breast Development. The Bergen Growth Study 2

Background: Using ultrasound to examine the glandular breast tissue is a promising method for staging pubertal breast development. However, breast ultrasound for this purpose has not been explored in a large sample of healthy girls in different developmental stages, and normative data have been unavailable.Objective: To present novel pubertal references for breast ultrasound stages, Tanner breast (B) and pubic hair (PH) ...

Endocrine Profiling and Association with Ultrasound Measured Testicular Volume and Biometrics in a Cohort of Norwegian Boys

Madsen André , Oehme Ninnie , Bruserud Ingvild , Roelants Mathieu , Sagen Jørn , Mellgren Gunnar , Júlíusson Pétur

Introduction: Male puberty is initiated by endocrine signaling in the hypothalamic-pituitary axis whereby follicle-stimulating hormone (FSH) and luteinizing hormone (LH) enable testicular maturation and synthesis of testosterone. Recent publications have eluded to overnutrition and obesity as relevant factors that may accelerate the timing of puberty. Attainment of testicular volume (TV) 4 ml measured by Prader orchidometer remains the definition of male puber...
