Brief summary: Current guidelines for congenital hypothyroidism recommend a starting dose of 10–15 μg/d of levothyroxine for optimal treatment (1). Over the last years, some studies suggested that overtreatment of patients during infancy by high levothyroxine doses might have negative effects on neurocognitive and behavioral development (2). The presented multicenter prospective randomized trial aimed at comparing the effect of higher (12.5–15.0 μg/d levoth...

AI is potentially life-threatening and requires lifelong glucocorticoid replacement therapy. Modified-release hydrocortisone preparations have bee...

Eur J Endocrinol. 2020; 183: 471–480. https://pubmed.ncbi.nlm.nih.gov/32738133/This cohort and nested case–control study analyzed the impact of growth hormone (GH) treatment on the risk of second neoplasm (SN) in a French cohort of 2852 childhood cancer survivors (CCS) treated before 1986. In total, 126 (64.3%) survivors who received GH had been treated for a brain tumor, 22 (11.2...

Nat Commun. 2020;11(1): 2673.https://pubmed.ncbi.nlm.nih.gov/32471973/The authors conducted an experimental study in male human volunteers to examine the effects of a neurokinin type 1 receptor (NK1R) antagonist on aldosterone secretion. The findings show the presence of Substance P (SP)-positive nerve fibres in the human adrenal cortex in the vicinity of aldosterone-producing cells and wit...

Although these recommendat...

Brief Summary: This study used chemogenetics and transgenic mouse models to show that glutamatergic neurotransmission in leptin responsive neurons in the premammillary nucleus is required for normal puberty and ovulation.Puberty and the acquisition of reproductive functions result from the reawakening of a complex neuroendocrine machinery eventually leading to the activation of GnRH secretion. Metabolic cues play a crucial role in regulating this system ...

Thus, homozygous loss-of-function mutations in the ACAN gene, encoding...

Brief Summary: This retrospective cohort study included 54 pre- or peri-pubertal boys affected by hematological cancer who underwent a testicular biopsy for fertility preservation at the time of diagnosis, before any gonadotoxic treatment. The presence of cancer cells in immature testicular tissue of young boys was assessed by histology, immunohistochemistry (IHC) and PCR at the time of cryopreservation, before treatment. Contamination by cancerous cells was found in 10/28 boy...

PMID: 35044839Brief Summary: This retrospective study showed that children and young adults (< 45 years) treated with radioactive iodine (RAI) for primary Differentiated Thyroid Cancer (DTC) have increased risks for leukemia and solid cancers, particularly beyond 20 years after treatment.<p class="abs...

To read the full abstract: J Nutr. 2020 Jun1;150(6):1405–1412.There is increasing evidence that dairy milk positively affects linear growth, weight and body composition in children, particularly in low- and middle-income countries (1)(2). This effect of milk on growth has been proposed to be mediated by IGF-I (2), (3). The aim of this double-blinded, controlled trial was to evaluate the effect of milk supplements on circulating IGF-I and to...
