To read the full abstract: J Clin Endocrinol Metab. 2020; 105(5): 1427–1434. PMID: 31853550.GDF15 is a stress-induced hormone that acts in the hindbrain to activate neural circuits involved in aversive responses and reducing food intake and body weight in animal models (1). In humans, GDF15 is widely expressed, with highest concentrations seen in placental trophoblasts, followed by kid...

8.18. Interaction between hypothalamic-pituitary-adrenal axis genetic variation and maternal behavior in the prediction of amygdala connectivity in children

E Pozzi , CA Bousman , JG Simmons , N Vijayakumar , O Schwartz , M Seal , MBH Yap , NB Allen , SL Whittle

To read the full abstract: Neuroimage. 2019; 197:493–501. PMID: 31077842.A large body of evidence suggests that the early environment can influence the health and wellbeing in children later in life. Variability in susceptibility to environmental stimuli might be mediated by interactions between genetic variations and the environment. The hypothalamic-pituitary adrenal (HPA) axis is th...

1.2. Cerebrospinal fluid vasopressin and symptom severity in children with autism

O Oztan , JP Garner , S Partap , EH Sherr , AY Hardan , C Farmer , A Thurm , SE Swedo , KJ Parker

To read the full abstract: Ann Neurol 2018;84:611–615This paper examined the concentrations of arginine vasopressin (AVP) and oxytocin (OXY) in the cerebrospinal fluid (CSF) of autistic children (n=36) compared to controls children without psychiatric disease who needed lumbar puncture for some medical reason (n=36). The authors hypothesized that if these neuropeptides are involved ...

3.11 DICER1 mutations are frequent in adolescent-onset papillary thyroid carcinoma

JD Wasserman , N Sabbaghian , S Fahiminiya , R Chami , O Mete , M Acker , MK Wu , A Shlien , L de Kock , WD Foulkes

To read the full abstract: J Clin Endocrinol Metab 2018;103:2009-2015Thyroid cancer in children and adolescents has a higher rate of regional and distant metastases, and recurrence rate than in adults. However, little is known about the molecular origin of thyroid carcinoma in children. DICER1 encodes for an endoribonuclease responsible for processing RNA into s...

To read the full abstract: J Endocr Soc 2017;1:1006-1011Besides its structural role in the extracellular matrix, aggrecan orchestrates a plethora of key mechanisms in endochondral ossification, such as embryonic morphogen distribution, regular indian hedgehog (IHH) / Sox9 expression and columnar chondrocyte orientation. Thus, homozygous loss-of-function mutations in the ACAN gene, encoding...

10.8 Association of insulin pump therapy vs insulin injection therapy with severe hypoglycemia, ketoacidosis, and glycemic control among children, adolescents, and young adults with T1DM

B Karges , A Schwandt , B Heidtmann , O Kordonouri , E Binder , U Schierloh , C Boettcher , T Kapellen , J Rosenbauer , RW Holl

To read the full abstract: JAMA. 2017;318:1358-1366Here, the authors compared the metabolic control in young patients with T1DM with insulin pump therapies versus multiple injection treatment modalities using the data from 30 579 patients younger than 20 years of age of 446 centers in a prospective population-based cohort study. While it is very clear that pump therapy, compared with injection ...

14.5 Environment dominates over host genetics in shaping human gut microbiota

D Rothschild , O Weissbrod , E Barkan , A Kurilshikov , T Korem , D Zeevi , PI Costea , A Godneva , IN Kalka , N Bar

To read the full abstract: Nature 2018;555:210Up to now, it was thought that genetics would play a major role in shaping the gut flora. However, this study, in a cohort of 1,046 healthy Israeli individuals with a well-defined clinical phenotype, suggests that only 2-8% of human microbiome variability is explained by genetics, as compared to 92-98% explained by environmental influences. This...

3.19. The synovial microenvironment suppresses chondrocyte hypertrophy and promotes articular chondrocyte differentiation

M Chau , Z Dou , M Baroncelli , EB Landman , A Bendre , M Kanekiyo , A Gkourogianni , K Barnes , L Ottosson , O Nilsson

In Brief: Growth plate and articular cartilage have similar structures composed of distinct chondrocyte layers but they differ substantially with respect to their function and fate. This study combines transplantation experiments with cell tracing in rat with in vitrostudies to identify a novel mechanism by which synoviocytes act directly on chondrocytes to suppress endochondral and promote articular cartilage at the joint surface.Commentary: Gr...

6.9. Leukocyte telomere length in children with congenital adrenal hyperplasia

C Raftopoulou , O Abawi , G Sommer , M Binou , G Paltoglou , CE Fluck , ELT van den Akker , E Charmandari

Brief summary: This prospective observational cohort study determined leukocyte telomere length (LTL) in 76 patients with genetically confirmed CAH (83% classic CAH). LTL was shorter in patients with classic vs nonclassic CAH, in overtreated than in optimally treated patients, and patients receiving prednisolone compared with hydrocortisone.Telomeres are tandem repeats of a noncoding hexameric nucleotide sequence (5′-TTAGGG-3′) located at the...
