Duncan et al. reviewed the response to growth hormone stimulation testing after priming in peripubertal children. The concern is that there is little research documenting the response to growth hormone treatment in patients with sex hormone primed growth hormone stimulation testing and those unprimed. The controversy about priming or not can be summarized as follows: if one wants to know if the production of growth hormone during puberty will be adequate in terms of peak growth hormone responses then stimulation with priming should be done...

OBJECTIVE: Interpreting thyroid function tests can be challenging due to inherent variation, and the need for tests rises with age. While age-related changes in thyrotropin (TSH) levels are known, the biological variation in older adults remains unclear. DESIGN: We recruited nineteen 65-99-year-old (older adults) without thyroid disease for monthly blood sampling for 1 year. PATIENTS AND MEASUREMENTS: Serum was stored at -20C°, and TSH, total thyroxine (TT4) and total triiodothyronine (TT3) were analysed in random order in a single batch for each participant...

DESIGN: The androgen receptor (AR) mediates peripheral effects of testosterone. Previous data suggests an association between the number of CAG repeats in exon-1 of the AR gene and AR transcriptional activity. The aim of this analysis was to determine the association between the number of AR CAG repeats and all-cause mortality in men and the influence of testosterone level on the association. PATIENTS AND MEASUREMENTS: Follow-up data to 27 January 2018 were available for men aged 40-79 years recruited across six countries of the European Male Aging Study between 2003 and 2005...

OBJECTIVE: Serum Anti-Mullerian Hormone (AMH) concentrations have been proposed as a marker of spontaneous puberty and future fertility in Turner syndrome (TS). Gonadotropins during minipuberty may also provide a clue to ovarian function but there is insufficient data to inform utility in the routine clinical management of TS. Our objective was to describe the distribution of AMH in a cross-sectional cohort of patients in a TS specialty clinic, and correlate with spontaneous puberty and karyotype, as well as gonadotropins during the minipuberty of infancy in a smaller subset of patients aged 2-9 months...

BACKGROUND AND OBJECTIVE: The risk of aortic dissection (AoD) is increased in women with Turner syndrome (TS) but predicting those with this heightened risk is difficult. In response to this, we sought to create a pathway to monitor TS patients to improve efficiency and resource utilisation in our dedicated TS clinic, and to monitor more closely those women thought to be at increased risk of AoD. DESIGN AND PATIENTS: Our pathway was designed based on evidence derived from International Guidelines for the management of aortic disease in women with TS...

BACKGROUND: Most patients diagnosed with thyroid cancer have low-risk disease, but some have a higher risk for persistent or recurrent disease and even death from thyroid cancer. Few studies have evaluated potential anthropometric, lifestyle, or dietary risk factors for advanced or aggressive types of thyroid cancer. METHODS: Using data from a large US cohort study, we examined associations for high-risk thyroid cancer (HRTC) and, separately, low-risk thyroid cancer (LRTC) in relation to anthropometric factors, diet, smoking, and alcohol consumption...

OBJECTIVE: Data are inconclusive regarding pregnancy complications associated with maternal chronic hypoparathyroidism. Therefore, we aimed to compare pregnancy, delivery and neonatal outcomes in patients affected by chronic hypoparathyroidism to those without chronic hypoparathyroidism. DESIGN: A retrospective population-based study utilising data from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample (HCUP-NIS) database over 11 years from 2004 to 2014 inclusively...

Congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency accounts for 95% of all CAH cases and is one of the most common inborn metabolic conditions. The introduction of life-saving glucocorticoid replacement therapy 70 years ago has changed the perception of CAH from a paediatric disorder into a lifelong, chronic condition affecting patients of all age groups. Alongside health problems that can develop during the time of paediatric care, there is an emerging body of evidence suggesting an increased risk of developing co-morbidities during adult life in patients with CAH...

OBJECTIVE: Cushing's syndrome is characterized by hypercortisolaemia and is frequently accompanied by comorbidities such as type 2 diabetes, hypertension, osteoporosis, depression and schizophrenia. It is unclear whether moderate but lifelong hypercortisolaemia is causally associated with these diseases in the general population. We aimed to address this research gap using a Mendelian randomization approach. METHODS: We used three cortisol-associated genetic variants in the SERPINA6/SERPINA1 region as genetic instruments in a two-sample, inverse-variance-weighted Mendelian randomization analysis...

OBJECTIVE: Polycystic ovary syndrome (PCOS) is a complex disorder with diverse metabolic implications. Diagnosis typically relies on oligo-amenorrhoea (OA), hyperandrogenism (HA), and polycystic ovarian morphology (PCOM). However, the role of polymenorrhoea in PCOS remains understudied. Additionally, limited information exists regarding metabolic disturbances in women with partial PCOS phenotypes that do not meet diagnostic criteria. This extensive database aims to provide substantial evidence on the metabolic implications of polymenorrhoea and partial PCOS phenotypes...

Monitoring of hormone replacement therapy represents a major challenge in the management of congenital adrenal hyperplasia (CAH). In the absence of clear guidance and standardised monitoring strategies, there is no consensus among clinicians regarding the relevance of various biochemical markers used in practice, leading to wide variability in their application and interpretation. In this review, we summarise the published evidence on biochemical monitoring of CAH. We discuss temporal variations of the most commonly measured biomarkers throughout the day, the interrelationship between different biomarkers, as well as their relationship with different glucocorticoid and mineralocorticoid treatment regimens and clinical outcomes...

To provide an overview of the I-CAH Registry. Following the successful roll-out of the I-DSD Registry in the 2000s, it was felt that there was a need for a registry for congenital adrenal hyperplasia (CAH) and this was launched in 2014 as a dedicated module within the original registry. In addition to supporting and promoting research, the I-CAH Registry acts as an international tool for benchmarking of clinical care and it does this through the collection of standardised data for specific projects. Surveillance of novel therapies in the field of CAH can also be achieved via global collaborations...

Patients with salt-wasting congenital adrenal hyperplasia (SW-CAH) usually show pronounced impairment of aldosterone secretion and, therefore, also require mineralocorticoid replacement. While a lot of research and discussion focusses on the glucocorticoid therapy in SW-CAH to replace the missing cortisol and to control adrenal androgen excess, very little research is dealing with mineralocorticoid replacement. However, recent data demonstrated an increased cardiovascular risk in adult CAH patients urging to reflect also on the current mineralocorticoid replacement therapy...

OBJECTIVE: Observational studies have shown that visceral adipose tissue (VAT) can increase the risk of nonalcoholic fatty liver disease (NAFLD). However, the causality of this association remains unclear. Therefore, this study aimed to explore the causal association between VAT and NAFLD. DESIGN: We obtained single-nucleotide polymorphisms strongly associated with VAT (n = 325,153) from large-scale genome-wide association studies. Summary-level data for NAFLD (2275 cases and 375,002 controls) was available from the FinnGen consortium...

BACKGROUND: Adult women with Turner syndrome (TS) have high rates of miscarriage, presumably due to the abnormal size and shape of the uterus. There is a paucity of data regarding the determinants of uterine volume (UtVol) in young girls with TS before the initiation of oestrogen replacement therapy (ERT). METHODS: We performed a cross-sectional study on premenarchal girls with TS, aged 5-15 years, pubertal stage B1-B3, not having received ERT (n = 73) and 50 age-matched healthy controls...

BACKGROUND: Routine clinical coding of clinical outcomes in outpatient consultations still lags behind the coding of episodes of inpatient care. Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT) offers an opportunity for standardised coding of key clinical information. Identifying the most commonly required SNOMED terms and grouping these into a reference set will aid future adoption in routine clinical care. OBJECTIVE: To create a common endocrinology reference set to standardise the coding for outcomes of outpatient endocrine consultations, using a semi-automated extraction of information from existing clinical correspondence...

OBJECTIVE: To explore the efficacy and safety of the 'Walk with you' application for titrating basal insulin (BI) doses in type-2 diabetes mellitus (T2DM) hospitalised patients. METHODS: This was a randomised, single-centre, open-label, controlled clinical trial to compare the changes in fasting blood glucose (FBG) and postprandial blood glucose (PBG), time to reach target FBG (FBG-TRT), incidence of hypoglycaemia events and FBG coefficient of variation in the application group (weight-based titration of BI dose regimen) and control group (typical adjustment regimen)...
