Diagnostic performance of ultrasound vs. ultrasound-guided FNAc in thyroid nodules: data from the ElaTION trial.Introduction: ElaTION is a large multi-centre pragmatic randomised controlled trial, performed in 18 secondary/tertiary hospitals across England, comparing elastography ultrasound-guided fine needle aspiration cytology (EUS-FNAC) with ultrasound-guided FNAC (US-FNAC) alone in the diagnostic assessment of thyroid nodules. Secondary trial outcomes, reported here, assessed the accuracy of ultrasound-alone (US) compared with US-guided FNAC to inform and update current practice guidelines. Methods: Adults with single or multiple thyroid nodules who had not undergone previous FNAC were eligible. Radiologists assessed all thyroid nodules using US alone, thereby enabling assessment of its accuracy (sensitivity and specificity) versus US-FNAC. Results: Of the 982 participants, a final definitive diagnosis was obtained in 688, who were included in the final analyses. The sensitivity of US-alone was the same as US-FNAC (0.91, [95% CI 0.85, 0.97] vs 0.87 [95%CI 0.80-0.95], p=0.37). US alone had statistically significant lower specificity than US-FNAC alone (0.48 vs 0.67 respectively, p<0.0001). The malignancy rate on histology in a nodule classified as benign on ultrasound (U2) was 9/263 (3.42%) and on cytology (Thy2) was 15/353 (4.25%), whereas the malignancy rate in a nodule that was benign on both (U2, Thy2) was 3/210 (1.43%). Malignancy risk for U3, U4, and U5 nodules was 68/304 (22.4%), 43/83 (51.8%), and 29/38 (76.3%) respectively (p<0.0001). Yet 80/982 (8%) patients were discharged despite having U3-U5 scans with Thy1 (non-diagnostic) FNAC and no definitive diagnosis.Malignancy risk was higher in smaller nodules: <10mm 23/60 (38.3%), 10-20mm 46/162 (28.4 %), and >20mm 80/466 (17.2%) (p<0.0001). Nodules with indeterminate cytology with atypical features (Thy3a) carried a similar malignancy risk to those with indeterminate cytology (Thy3/3f): 27/95 (28.4%) versus 42/113 (37.2%) respectively (p=0.18). Conclusion: Ultrasound alone appears to be an effective diagnostic modality in thyroid nodules, confirming the recommendations of recent guidelines and the BTA classification. However, findings also suggest caution regarding existing recommendations for conservative management of non-diagnostic (Thy1/Bethesda I) and atypical (Thy3a/Bethesda III) nodules. In those cases, ultrasound (U3-5) features may help identify high-risk subgroups for more proactive management.

Protocol for a feasibility and acceptability study for UK general population paediatric type 1 diabetes screening-the EarLy Surveillance for Autoimmune diabetes (ELSA) studyAim: The EarLy Surveillance for Autoimmune (ELSA) study aims to explore the feasibility and acceptability of UK paediatric general population screening for type 1 diabetes. Methods: We aim to screen 20,000 children aged 3-13 years for islet-specific autoantibodies through dried blood spot sample collection at home, hospital or community settings. Children with two or more autoantibodies are offered metabolic staging via oral glucose challenge testing. Feasibility assessments will compare recruitment modalities and uptake according to demographic factors (age, gender, ethnicity, level of deprivation and family history of diabetes) to determine optimal approaches for general population screening. The study is powered to identify 60 children (0.3%) with type 1 diabetes (stage 1-3). Parents are invited to qualitative interviews following ELSA completion (child screened negative or positive, single autoantibody or multiple, stage 1-3) to share their screening experience, strengths of the programme and any areas for improvement (acceptability assessments). Parents who decline screening or withdraw from participation are invited to interview to explore any concerns. Finally, we will interview professional stakeholders delivering the ELSA study to explore barriers and facilitators to implementation. Conclusion: Early detection of type 1 diabetes allows insulin treatment to be started sooner, avoids diagnosis as an emergency, gives families time to prepare and the opportunity to benefit from future prevention trials and treatments. ELSA will provide essential feasibility and acceptability assessments for UK general population screening to inform a future national screening programme for paediatric type 1 diabetes.

To establish the utility of neck circumference as a novel and simple risk marker for detection of metabolic syndrome and cardiometabolic risk factors in IndiansIntroduction: Waist circumference (WC) is used as a measure of metabolic syndrome (MeS); neck circumference (NC) can predict MeS. It is simpler to measure and may provide an indication of obstructive sleep apnea (OSA). Materials and methods: NC was measured. The mean NC was correlated with the markers of MeS and sleep apnea. Results: A total of 183 participants were recruited in the study. The average age was 48.13 ± 13.3 years in men and 48.09 ± 11.1 years in women. The mean body mass index (BMI) was 26.42 ± 4.69 kg/m2 in men and 28.25 ± 4.92 kg/m2 in women. The mean WC in men and women were 91.1 ± 12.92 cm and 90.86 ± 12.7 cm, respectively, while the NC was 38.4 ± 6.60 cm in men and 33.9 ± 2.40 cm in women. MeS was diagnosed in 17.6% of men and 12.7% of women. Sleep apnea was noted in 33.1% of males and 29.2% of females. There was a positive correlation between the NC and systolic blood pressure (SBP) (r = 0.316 in males), fasting blood glucose (FBG) (r = 0.522 in males and 0.263 in females), triglyceride (TG) (r = 0.172 in males; 0.320 in females), while high-density lipoprotein cholesterol (HDL-C) showed a negative correlation in males and females. There was a positive correlation of NC with sleep duration in both males and females (r = 0.346 in males and 0.344 in females). Those with a NC of <35 cm had a sleep score of 7, while those with a NC of >35 cm had a score of 15, showing poor sleep quality. Conclusion: NC was comparable to WC and waist-hip ratio (WHR) for cardiometabolic risk factors and also showed a good association with sleep apnea.

The impact of closed-loop automated insulin delivery systems on hypoglycaemia awareness in people living with type 1 diabetes: a systematic review and meta-analysisObjectives: Impaired awareness of hyperglycaemia (IAH) affects approximately 20-40% of people living with type 1 diabetes (T1D), predisposing them to severe hypoglycaemia. This systematic review evaluated the efficacy of closed-loop automated insulin delivery systems (CL-AID) in restoring IAH compared with standard diabetes care, including other diabetes technologies. Methods: Six electronic databases were searched for published and unpublished observational and randomised-control studies (RCTs) from inception to 29th of May 2024. The results of observational studies and RCTs were meta-analysed separately to calculate the effect of CL-AID on IAH in people living with T1D. Quality assessment of studies was performed using the Joanna-Briggs appraisal tool for cohort studies and the Risk of Bias (Rob-2) tool for RCTs. Results: Meta-analysis of four prospective observations studies (n = 583) demonstrated a statistically significant improvement in hypoglycaemia awareness upon transition to a hybrid closed-loop (HCL) system compared with standard diabetes care in people with T1D, Clarke score mean difference (MD) of -0.45 (-0.69 to -0.22, p = 0.0001). However, this was less than 1 point, which is the minimum clinically important difference (MCID) of Clarke score. Meta-analysis of three RCTs (n = 55) comparing standard diabetes care did not demonstrate any statistically significant effect on hypoglycaemia awareness, Clarke score MD of -0.69 (-1.89 to 0.50, p = 0.26). Conclusions: This systematic review demonstrated that transition from standard diabetes care to HCL has the potential to improve hypoglycaemia awareness in people with T1D and IAH, but this might not be of major clinical significance. Hence, psychoeducational interventions continue to be the cornerstone of IAH management. Novel therapeutic modalities, such as bi-hormonal automated delivery systems, need to be further explored to help restore hypoglycaemia awareness.

Efficacy of continuous glucose monitoring in people living with diabetes and end stage kidney disease on dialysis: a systematic reviewBackground: Patients with diabetes on dialysis experience wide variations in glucose levels and an increased risk of hypoglycaemia. Due to the inaccuracies of HbA1c in dialysis patients, JBDS-IP and KDIGO recommend the use of continuous glucose monitoring (CGM). We conducted a systematic review to examine the current evidence for CGM use and its impact on clinical outcomes in patients with diabetes on dialysis. Methods: A search of MEDLINE(R) ALL, Ovid Emcare, Journals@Ovid Full Text and Embase databases were conducted. Clinical or observational trials in adults with Type 1(T1D) or Type 2 (T2D) diabetes on dialysis and CGM intervention reporting on glycaemic outcomes were included. Results: Of the 936 citations identified, 49 duplicates were removed. 887 citations were screened by title and abstract. 9 full texts were reviewed and a further 7 excluded due to duplications or failure to meet to selection criteria. Data was extracted for 2 studies, both prospective before-and-after interventional studies with no control group. Joubert et al. (2015) showed results for 15 participants with T1D. Mean CGM glucose level decreased from 8.37mmol/L at baseline to 7.7mmol/L at the end of the CGM period (p < 0.05) while HbA1c decreased from 6.9 to 6.5% (p < 0.05) during the same period. Mean CGM was lower on dialysis days (7.68mmol/L vs. 7.8mmol/L, p < 0.05). Képénékian et al. (2014) reported on data from 29 T2D patients. Following a 3 month CGM-adapted insulin regimen, HbA1c decreased from 8.4% at baseline to 7.6% (p < 0.01) by the end of study. Mean CGM values decreased from 9.9mmol/L to 8.9mmol/L (p = 0.05) and the frequency of glucose values > 10mmol/L decreased from 41 to 30% (p < 0.05), without a significant increase in hypoglycaemia frequency. Both studies were deemed to be of 'good' quality. Conclusion: Evidence demonstrating the benefits of CGM in patients with diabetes receiving dialysis is lacking. There is a need for well-designed randomised controlled trials to ascertain the benefits of this technology in this patient group.

Report from the HarmoSter study: impact of calibration on comparability of LC-MS/MS measurement of circulating cortisol, 17OH-progesterone and aldosteroneObjectives: Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is recommended for measuring circulating steroids. However, assays display technical heterogeneity. So far, reproducibility of corticosteroid LC-MS/MS measurements has received scant attention. The aim of the study was to compare LC-MS/MS measurements of cortisol, 17OH-progesterone and aldosterone from nine European centers and assess performance according to external quality assessment (EQA) materials and calibration. Methods: Seventy-eight patient samples, EQA materials and two commercial calibration sets were measured twice by laboratory-specific procedures. Results were obtained by in-house (CAL1) and external calibrations (CAL2 and CAL3). We evaluated intra and inter-laboratory imprecision, correlation and agreement in patient samples, and trueness, bias and commutability in EQA materials. Results: Using CAL1, intra-laboratory CVs ranged between 2.8-7.4%, 4.4-18.0% and 5.2-22.2%, for cortisol, 17OH-progesterone and aldosterone, respectively. Trueness and bias in EQA materials were mostly acceptable, however, inappropriate commutability and target value assignment were highlighted in some cases. CAL2 showed suboptimal accuracy. Median inter-laboratory CVs for cortisol, 17OH-progesterone and aldosterone were 4.9, 11.8 and 13.8% with CAL1 and 3.6, 10.3 and 8.6% with CAL3 (all p<0.001), respectively. Using CAL1, median bias vs. all laboratory-medians ranged from -6.6 to 6.9%, -17.2 to 7.8% and -12.0 to 16.8% for cortisol, 17OH-progesterone and aldosterone, respectively. Regression lines significantly deviated from the best fit for most laboratories. Using CAL3 improved cortisol and 17OH-progesterone between-method bias and correlation. Conclusions: Intra-laboratory imprecision and performance with EQA materials were variable. Inter-laboratory performance was mostly within specifications. Although residual variability persists, adopting common traceable calibrators and RMP-determined EQA materials is beneficial for standardization of LC-MS/MS steroid measurements.

Testosterone replacement therapy: effects on blood pressure in hypogonadal menPurpose: While testosterone therapy can improve the various pathologies associated with adult-onset testosterone deficiency (TD), Summary of Product Characteristics (SPC) of five testosterone preparations caution that treatment may be associated with hypertension. This paper evaluates the impact of testosterone undecanoate (TU) on blood pressure (BP) in men with adult-onset TD. Materials and methods: Of 737 men with adult-onset TD in an on-going, observational, prospective, cumulative registry, we studied changes in BP using non-parametric sign-rank tests at final assessment and fixed time points. We used multiple regression analysis to establish factors (baseline BP, age, change/baseline waist circumference [WC] and hematocrit [HCT] and follow-up) potentially associated with BP change in men on TU. Results: TU was associated with significant reductions in systolic, diastolic BP and pulse pressure, regardless of antihypertensive therapy (at baseline or during follow-up), larger reductions were seen with concurrent antihypertensive therapy. In men never on antihypertensive agents, median changes (interquartile range [IQR]) in systolic BP, diastolic BP and pulse pressure were -12.5 (-19.0, -8.0), -8.0 (-14.0, -3.0), and -6.0 (-10.0, -1.0) mmHg, respectively at final assessment, with only baseline BP values inversely associated with these changes (HCT and WC were not significantly associated). In men not on TU, systolic BP, diastolic BP, and pulse pressure significantly increased. In the TU treated men only 1 of the 152 men (not on antihypertensive agents at baseline) were started on antihypertensives during follow-up. In contrast 33 of the 202 men on antihypertensives (at baseline or follow-up) had the antihypertensive agent discontinued by the end of the follow-up. Conclusions: TU was associated with lowering of BP during follow-up irrespective of antihypertensive therapy, with greater reductions in men with higher baseline BP. In the context of SPC warnings, our long-term data provide reassurance on the effect of TU on BP.

Findings from a public engagement programme for school children aged 13-15 years about endocrinologyObjectives: To investigate the utility and effectiveness of a school outreach programme in areas of lower socioeconomic status to improve understanding of common endocrine topics and the medical profession. Methods: Two secondary school outreach sessions were conducted in July 2022. Students were invited to attend lectures delivered by medical professionals and engage in poster-making sessions using the knowledge they had gained throughout the day. Participants completed anonymised pre- and post-session surveys. Outcomes were identified using Kirkpatrick's training evaluation model. Self-reported perceptions and beliefs (Kirkpatrick's level 2a) were compared using chi-square tests. Thematic analysis of team-led poster presentations was performed. Results: Of the 254 participants included, the response rates of pre- and post-session questionnaires were 75.6% and 56.2%, respectively. The outreach day increased students' understanding of obesity and diabetes, polycystic ovary syndrome, and Health Technology. The most well-received activities from the outreach day were voted to be the poster challenge (43.4%) and poster presentation (14.7%). Following the session, there was a trend towards an increased understanding of medical careers and interest in pursuing a medical career, although these did not reach statistical significance. Conclusions: Outreach programmes could be a practical and effective approach to engaging prospective medical applicants from areas of lower socioeconomic status. Further studies are required to expand outreach programmes and investigate the efficacy of school engagement programmes.

Type 1 diabetes in care homes: a practical guide on managementThe primary purpose of the original NAPCHD project was to develop a national Strategic Document of Diabetes Care for Care Homes which has now been completed and well received as a worthwhile, sustainable, and effective guidance for delivering quality diabetes care in the UK. A Working Group of NAPCHD was established to produce a Position Statement on type 1 diabetes in care homes since this area was recommended as a topic to further develop. There are currently limited data on the prevalence and clinical outcomes associated with type 1 diabetes in care homes and management policies have been non-existent in the UK. Communication among all key stakeholders involved in direct care of residents with type 1 diabetes is generally fragmented and lacks coordination. This is compounded by a slowly growing utilisation of diabetes technology and the absence of a standard/agreed community-based model of interdisciplinary collaboration. The Rationale and Objectives were defined prior to commencing the work and a work plan with individual tasks was initially set out. After multiple correspondences and Team calls over a period of 9 months, the Group successfully generated a first draft in October 2023. This draft was then finalised the following month and circulated among stakeholders for feedback. Nine chapters have been provided including minimum standards of diabetes care, insulin regimens, avoiding hospitalisation and discharge planning. A scheme for a community-based model of care for type 1 diabetes has been included. Eight key messages were developed. In addition, an Appendix has been created which includes key assessments such as nutritional assessment, detection of frailty, sick day rules and foot risk stratification

A SIMBA CoMICs initiative to cocreating and disseminating evidence-based, peer-reviewed short videos on social media: mixed methods prospective studyBackground: Social media is a powerful platform for disseminating health information, yet it is often riddled with misinformation. Further, few guidelines exist for producing reliable, peer-reviewed content. This study describes a framework for creating and disseminating evidence-based videos on polycystic ovary syndrome (PCOS) and thyroid conditions to improve health literacy and tackle misinformation. Objective: The study aims to evaluate the creation, dissemination, and impact of evidence-based, peer-reviewed short videos on PCOS and thyroid disorders across social media. It also explores the experiences of content creators and assesses audience engagement. Methods: This mixed methods prospective study was conducted between December 2022 and May 2023 and comprised five phases: (1) script generation, (2) video creation, (3) cross-platform publication, (4) process evaluation, and (5) impact evaluation. The SIMBA-CoMICs (Simulation via Instant Messaging for Bedside Application-Combined Medical Information Cines) initiative provides a structured process where medical concepts are simplified and converted to visually engaging videos. The initiative recruited medical students interested in making visually appealing and scientifically accurate videos for social media. The students were then guided to create video scripts based on frequently searched PCOS- and thyroid-related topics. Once experts confirmed the accuracy of the scripts, the medical students produced the videos. The videos were checked by clinical experts and experts with lived experience to ensure clarity and engagement. The SIMBA-CoMICs team then guided the students in editing these videos to fit platform requirements before posting them on TikTok, Instagram, YouTube, and Twitter. Engagement metrics were tracked over 2 months. Content creators were interviewed, and thematic analysis was performed to explore their experiences. Results: The 20 videos received 718 likes, 120 shares, and 54,686 views across all platforms, with TikTok (19,458 views) and Twitter (19,678 views) being the most popular. Engagement increased significantly, with follower growth ranging from 5% on Twitter to 89% on TikTok. Thematic analysis of interviews with 8 out of 38 participants revealed 4 key themes: views on social media, advice for using social media, reasons for participating, and reflections on the project. Content creators highlighted the advantages of social media, such as large outreach (12 references), convenience (10 references), and accessibility to opportunities (7 references). Participants appreciated the nonrestrictive participation criteria, convenience (8 references), and the ability to record from home using prewritten scripts (6 references). Further recommendations to improve the content creation experience included awareness of audience demographics (9 references), sharing content on multiple platforms (5 references), and collaborating with organizations (3 references). Conclusions: This study demonstrates the effectiveness of the SIMBA CoMICs initiative in training medical students to create accurate medical information on PCOS and thyroid disorders for social media dissemination. The model offers a scalable solution to combat misinformation and improve health literacy.

Exogenous opioids and the human endocrine system: an endocrine society scientific statement.The use and misuse of opioids are a growing global problem. Although the effects of these drugs on the human endocrine system have been studied for decades, attention on their related clinical consequences, particularly on the hypothalamic-pituitary system and bone health, has intensified over recent years. This Statement appraises research data related to the impact of opioids on the gonadal and adrenal function. Whereas hypogonadism is well recognized as a side effect of opioids, the significance of their inhibitory actions on the hypothalamic-pituitary-adrenal system and the occurrence of clinically relevant adrenal insufficiency is not fully elucidated. The often-inconsistent results of studies investigating how opioids affect the secretion of GH, prolactin, arginine vasopressin, and oxytocin are assessed. The accumulating evidence of opioid actions on bone metabolism and their negative sequelae on bone mineral density and risk of fracture are also reviewed. In each section, available data on diagnostic and management approaches for opioid endocrine sequelae are described. This Statement highlights a plethora of gaps in research associated with the effects and clinical consequences of opioids on the endocrine system. It is anticipated that addressing these gaps will improve the care of people using or misusing opioids worldwide. The Statement is not intended to serve as a guideline or dictate treatment decisions.

Presentation and management of patients with adrenal masses: a large tertiary centre experience.Background: Adrenal masses are found in up to 5%-7% of adults. The 2016 European guidelines on the management of adrenal incidentalomas have standardised the workup of these patients, but evidence of their impact on clinical practice is lacking. Methods: Retrospective review of clinical presentation, radiological characteristics, and final diagnosis of a large cohort of patients with adrenal masses referred to a tertiary care centre 1998-2022. Sub-analysis compares outcomes before and after implementing the 2016 guidelines. Results: A total of 1397 patients (55.7% women; median age 60 years [interquartile range {IQR}, 49-70]) were included. Incidental discovery was the most frequent mode of presentation (63.7%) and 30.6% of patients had masses ≥ 4 cm (median 2.9 cm [IQR, 1.9-4.7]). Unenhanced computed tomography Hounsfield units (HU) were available for 763 patients; of these, 32.9% had heterogeneous masses or >20 HU. The most common diagnoses were adrenocortical adenoma (56.0%), phaeochromocytoma (12.7%), adrenocortical carcinoma (10.6%), and metastases (5.7%). At multivariable analysis, significant predictors of malignancy included >20 HU or heterogeneous density (odds ratio [OR] 28.40), androgen excess (OR 27.67), detection during cancer surveillance (OR 11.34), size ≥ 4 cm (OR 6.11), and male sex (OR 3.06). After implementing the 2016 guidelines, the number of adrenalectomies decreased (6.1% pre-2016 vs 4.5% post-2016) and the number of patients discharged increased (4.4% pre-2016 vs 25.3% post-2016) for benign non-functioning adrenal masses. Conclusion: Implementing the 2016 guidelines positively impacted clinical practice, reducing unnecessary surgeries and increasing the discharge rate for benign adrenal masses, thereby preserving healthcare resources and patient burden.

Current management of chronic kidney disease in type-2 diabetes-A tiered approach: An overview of the joint Association of British Clinical Diabetologists and UK Kidney association (ABCD-UKKA) guidelines.A growing and significant number of people with diabetes develop chronic kidney disease (CKD). Diabetes-related CKD is a leading cause of end-stage kidney disease (ESKD) and people with diabetes and CKD have high morbidity and mortality, predominantly related to cardiovascular disease (CVD). Despite advances in care over the recent decades, most people with CKD and type 2 diabetes are likely to die of CVD before developing ESKD. Hyperglycaemia and hypertension are modifiable risk factors to prevent onset and progression of CKD and related CVD. People with type 2 diabetes often have dyslipidaemia and CKD per se is an independent risk factor for CVD, therefore people with CKD and type 2 diabetes require intensive lipid lowering to reduce burden of CVD. Recent clinical trials of people with type 2 diabetes and CKD have demonstrated a reduction in composite kidney end point events (significant decline in kidney function, need for kidney replacement therapy and kidney death) with sodium-glucose co-transporter-2 (SGLT-2) inhibitors, non-steroidal mineralocorticoid receptor antagonist finerenone and glucagon-like peptide 1 receptor agonists. The Association of British Clinical Diabetologists (ABCD) and UK Kidney Association (UKKA) Diabetic Kidney Disease Clinical Speciality Group have previously undertaken a narrative review and critical appraisal of the available evidence to inform clinical practice guidelines for the management of hyperglycaemia, hyperlipidaemia and hypertension in adults with type 2 diabetes and CKD. This 2024 abbreviated updated guidance summarises the recommendations and the implications for clinical practice for healthcare professionals who treat people with diabetes and CKD in primary, community and secondary care settings.

The impact of the COVID-19 pandemic on mobility trends and the associated rise in population-level physical inactivity: insights from international mobile phone and national survey data.Introduction: The COVID-19 pandemic has reduced physical activity (PA) levels. This is important as physical inactivity is linked to poor COVID-19 outcomes. This study aimed to assess the impact of COVID-19 pandemic restrictions on greenspace and residence mobility, walking levels and in turn how these translated to trends in (UK) PA levels. Methods: Google Mobility Reports, the Oxford COVID-19 Government Response Tracker and Apple Mobility geospatial datasets were interrogated for international data. Residence mobility represents home mobility, greenspace mobility includes parks, walking direction requests is proportion of walking directions; stringency index measures lockdown intensity. The Sports England Active Lives Survey dataset was assessed for complementary changes in English PA levels. Results: Using mobility data of 10 countries we observed that during lockdown there were reductions in greenspace mobility and walking directions alongside increased residence mobility; more pronounced changes were seen in countries with higher stringency indices. From a UK perspective, complementary English PA survey data demonstrated the impact of these mobility changes on the proportion and demographic characteristics of PA levels. The most vulnerable in society, the elderly (ages 75+) and Black and Asian minority ethnicity (BAME) individuals were more likely to become physically inactive. Conclusions: The COVID-19 pandemic reduced greenspace mobility and walking direction requests globally. Complementary assessment of English PA levels demonstrated a greater proportion of the population became inactive. Demographics (75+ and BAME) prone to worse COVID-19 outcomes became disproportionately inactive. UK Urban planning should prioritize greenspace development. This could improve city walkability and PA levels.

The relationship between intact parathyroid hormone and 25-hydroxyvitamin D in United Kingdom resident south Asians and Whites: a comparative, cross-sectional observational study.Ethnic differences in intact parathyroid hormone (iPTH) at similar total 25 hydroxyvitamin D [25(OH)D] concentrations have been reported between US resident Whites, Blacks, and Hispanics, but this has not been studied between South Asians and Whites. We, therefore, compared the iPTH relationship to 25(OH)D in UK resident South Asians and Whites. A comparative, cross-sectional observational study in which demographic and laboratory data on South Asian and White residents of Wolverhampton, UK were analyzed. Log-log models measured the association between 25(OH)D and the interaction term of ethnicity and iPTH. Seven hundred and seventy-two patients consisting of 315 white subjects (208 women) and 457 South Asian subjects (331 women) were studied. Compared to South Asians, White subjects were older, had higher serum concentrations of 25(OH)D, creatinine (lower eGFR), adjusted calcium and magnesium, but similar concentrations of iPTH and phosphate. In an adjusted model, variables significantly associated with 25(OH)D included age, creatinine, adjusted calcium and ethnicity; but not iPTH and the interaction term of ethnicity and iPTH (beta coefficient -0.071, 95% CI -0.209, 0.067, p=0.32). In our study cohort, iPTH was not, per se, influenced by 25 (OH)D. We found no ethnic differences in the association between iPTH and 25(OH)D between South Asians and White UK residents.

Presentation and characteristics of children with screen-detected type 1 diabetes: learnings from the ELSA general population pediatric screening studyIntroduction: We describe the identification and management of general population screen-detected type 1 diabetes (T1D) and share learnings for best practice. Research design and methods: Children diagnosed with T1D through a general population screening initiative, the EarLy Surveillance for Autoimmune diabetes (ELSA) study, were reviewed and described.Parents provided written, informed consent for inclusion in the case series. Results: 14 children with insulin requiring (stage 3) T1D are described. These cases offer unique insights into the features of screen-detected T1D. T1D is identified sooner through screening programs, characterized by absent/short symptom duration, median presenting glycated hemoglobin 6.6% (49 mmol/mol) and insulin requirements<0.5 units/kg/day. ELSA identified four children at stage 3 and another 4 progressed within 4 months of ELSA completion, including two single seropositive children. Six children developed stage 3 T1D prior to ELSA completion, including two children (14%, n=2/14) with diabetic ketoacidosis prior to confirmed antibody status. Conclusions: There are three main learnings from this case series. First, T1D identified through screening is at an earlier stage of its natural history and requires personalized insulin regimens with lower total daily insulin doses. Second, single autoantibody seropositivity can rapidly progress to stage 3. Finally, insulin requirement can manifest at any stage of the T1D screening pathway, and therefore early education around symptom recognition is essential for families participating in screening programs.

The effects of somatostatin analogues on glycaemia in the treatment of neuroendocrine tumoursLong-acting somatostatin analogues (SSAs) are the most commonly used drugs in the management of neuroendocrine tumours (NETs) because of their ability to control symptoms and prolong survival. SSA use is associated with changes in glucose metabolism. However, the impacts on glycaemic control and body mass index (BMI) caused by SSAs in NETs are largely unknown. In the present study, we evaluated the effects of SSA treatment on BMI and glycated haemoglobin (HbA1c) in our cohort of patients with NETs. We also assessed changes in glycaemic control and BMI before and after SSA treatment. In addition, we assessed the incidence of new diabetes or whether there was worsening of glycaemic control for patients with pre-existing diabetes. The study comprised a retrospective study of 279 patients with NETs who were treated with SSAs between January 2014 and January 2019. Glycaemic control was assessed by measuring changes in Hba1c. A number needed to harm analysis was used to look at new cases of diabetes within the study population. Treatment with SSAs was associated with a mean increase in HbA1c of 3.35 ± 6.30 mmol mol-1 despite a mean decrease in BMI of -1.04 ± 2.79 kg m-2 . There were 19 new cases of type 2 diabetes mellitus (T2DM) in the population of 209 with a number needed to harm of 12.5. Of the 34 patients with pre-existing T2DM, five had worsening of their mean HbA1c. Treatment with SSAs for NETs is associated with an increase in HbA1c, despite a reduction in BMI and, importantly, a risk of developing T2DM with a number needed to harm of 12.5. This project was registered with the National Health Service Clinical Audit and Registries. It has a CARMS number - 17666.
