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...

2.1. Serum IGF-1 to IGFBP-3 molar ratio: a promising diagnostic tool for growth hormone deficiency in children

LM Haj-Ahmad , MM Mahmoud , NWG Sweis , I Bsisu , AM Alghrabli , AM Ibrahim , AA Zayed

Brief summary: This cross-sectional study provided evidence regarding the usefulness of serum IGF-1/IGFBP-3 ratio as a marker for the diagnosis of GHD in children.Diagnosis of growth hormone deficiency (GHD) is still challenging, due to the insufficient specificity of GH stimulation tests. Serum IGF-1, IGFBP-3, and their combination have been proposed as an alternative to GH stimulation tests. However, despite relatively high specificity, their validity ...

10.17. Non-invasive quantification of stem cell-derived islet graft size and composition

V Lithovius , S Lahdenpohja , H Ibrahim , J Saarimaki-Vire , L Uusitalo , H Montaser , al. et

Brief Summary: This experimental study used positron emission tomography (PET) as non-invasive method to monitor stem cells-islet grafts. [18F]exendin and [18F]FDOPA PET showed potential as non-invasive methods to assess stem cells-islet graft size and aspects of graft composition.Stem cell-derived islets (SC-islets) are used as an emerging cell replacement therapy for insulin-dependent diabetes (1). Non-invasive long-term monitorin...

To read the full abstract: J Clin Endocrinol Metab. 2020; 105(3): dgz145. PMID: 31665349.Prenatal treatment with glucocorticoids (GC) is used in several clinical indications. However, the long-term outcome on offspring metabolic, somatic and cognitive health has raised significant concern. In rodents, high glucocorticoid levels inhibit development of beta cells during fetal life and lead to...
