1. Pituitary and Neuroendocrinology

Wang Yafei , Hietamaki Johanna , Varimo Tero , Hero Matti , Miettinen Paivi J , Raivio Taneli

PrefaceIn this first chapter of the Yearbook, we present recent advances in the development/ontogeny of the pituitary, genetics of hypopituitarism, clinical and translational aspects, and lastly we describe two papers on the relationship between pituitary function and viral disease. We hope that our selection of papers is both educational and interesting to all readers....

1.3. Lineage analysis reveals an endodermal contribution to the vertebrate pituitary

P Fabian , KC Tseng , J Smeeton , JJ Lancman , PDS Dong , R Cerny , JG Crump

Science. 2020 Oct 23;370(6515):463-467. doi: 10.1126/science.aba4767. PMID: 33093109These researchers used lineage tracing, combined time-lapse imaging with single cell RNA sequencing in zebrafish, and identified that endoderm actually also contributes to the formation of adenohypophysis primordium and resultant pituitary.The pituitary gland is considered to be forme...

2.5. SUR1-mutant iPS cell-derived islets recapitulate the pathophysiology of congenital hyperinsulinism.

V Lithovius , J Saarimaki-Vire , D Balboa , H Ibrahim , H Montaser , T Barsby , T Otonkoski

Diabetologia. 2021 Mar;64(3):630-640. doi: 10.1007/s00125-020-05346-7. PMID: 33404684.The derivation of iPSCs and their subsequent conversion to islet like clusters from a patient with diffuse CHI due to a homozygous mutation in the ABCC8 provided these authors a unique opportunity to study the molecular basis of CHI and to develop potential novel treatment options by screening...

2.23. Maternal organophosphate flame-retardant exposure alters offspring energy and glucose homeostasis in a sexually dimorphic manner in mice

SN Walley , EA Krumm , A Yasrebi , J Kwiecinski , V Wright , C Baker , TA Roepke

J Appl Toxicol. 2021 Apr;41(4):572–586. doi: 10.1002/jat.4066. PMID: 329695In this study, pregnant dams were exposed to different types of organophosphate flame retardants (OPFRs) at a sensitive development period (from gestation to lactation). The offspring were fed either a high or a low-fat diet for 17 weeks and then underwent a battery of metabolic assessments. OPFR exposure did not alte...

3.9. Newborn screening TSH values less than 15 mIU/L are not associated with long-term hypothyroidism or cognitive impairment

R West , J Hong , JGB Derraik , D Webster , NL Heather , PL Hofman

J Clin Endocrinol Metab. 2020;105:dgaa415. doi: 10.1210/clinem/dgaa415.The optimal cut-off for neonatal screening has long been a matter of debate. The optimal balance between optimal detection of cases and increase of false positive patients is difficult to define. Also, in the most recent guidelines for congenital hypothyroidism (see previous paper in this chapter 3.7), no precise cut-off...

4.8. Longitudinal study on metabolic health in adults SGA during 5 years after GH with or without 2 years of GnRHa treatment

Goedegebuure Wesley J. , van der Steen Manouk , Kerkhof Gerthe F , Hokken-Koelega Anita CS

J Clin Endocrinol Metab, August 2020, 105(8):e2796–e2806. doi: 10.1210/clinem/dgaa287. PMID: 32436961The aim of this longitudinal study was to investigate the potential long-term adverse effects of combined GnRHa/GH treatment on metabolic and bone health in short SGA children. Reassuring data are found at 5 years after cessation of GH therapy.Children born small ...

6.14. Thrombosis Risk in Transgender Adolescents Receiving Gender-Affirming Hormone Therapy

ES Mullins , R Geer , M Metcalf , J Piccola , A Lane , LAE Conard , TLK Mullins

Pediatrics. 2021 Mar 22:e2020023549. doi: 10.1542/peds.2020-023549. PMID: 33753543.This retrospective, single center chart review study assessed the incidence of arterial or venous thrombosis during gender affirming hormone therapy (GAHT) in 611 transgender adolescents. The prevalence of thrombosis risk factors was also investigated. No increased risk of thrombosis was found over a short ...

9.15. Risk of adrenal insufficiency following intra-articular or periarticular corticosteroid injections among children with chronic arthritis

J Turmel-Roy , MA Bedard , M Millette , D Simonyan , JP Proulx-Gauthier , I Rousseau-Nepton

J Pediatr Endocrinol Metab. 2020; 33: 1257–1263. https://pubmed.ncbi.nlm.nih.gov/32845867/This retrospective study evaluated the prevalence of adrenal insufficiency after a single intra-articular corticosteroid injection (IACI) in 60 children with chronic arthritis. Adrenal insufficiency was diagnosed in 30% (18/60) and was associated with higher doses of injected corticosteroid. Media...

Pediatr Diabetes. 2020;21(8):1447–1456. doi: 10.1111/pedi.13122Family histories suggest strong degrees of inheritance of T1D in some children, especially in populations with an overall high risk of autoimmunity.This paper from the Finnish T1D Prediction and Prevention (DIPP) study looked at subjects carrying high HLA-conferred risk for T1D. A family history of T1D in...
