Background: Vitamin D deficiency (VDD) has been implicated in the pathophysiology of respiratory infections, including Coronavirus Disease 2019 (COVID-19). We assessed vitamin D levels of patients who died from COVID-19 during or following admission to Newcastle-upon-Tyne Hospitals.Methods: We performed a retrospective survey of electronic patient records for 2,355 patients admitted to our institution between 04/02/2020 and 19/01/2021, who had a positive...

The FGF signalling pathway regulates cell proliferation, differentiation, migration and cell specification in mutliple developing and adult tissues. It has also been implicated in tumor development and progression with a significant role in the cancer pathobiology of several malignant tumors including melanoma, breast, pancreas, head and neck and non-small lung cell cancer. FGF signalling plays a major role in the postnatal hypothalamic-pituitary (HP) axis, with dysregulation ...

Introduction: Central diabetes insipidus (DI) is a frequent complication of transfenoidal surgery for Cushing’s disease (CD). It can be transient or, more infrequently, permanent. The most common mechanism results from surgical neurohypophyseal damage rather than local mass effect from the pituitary adenoma.Case report: A 40 years old woman was referred to our Endocrinology outpatient clinic at the beginning of 2015 for new onset hypertension, signi...

Liver-expressed antimicrobial peptide 2 (LEAP-2) has been recently characterized as an endogenous GHSR1a antagonist. LEAP-2 is produced mainly in the liver, and it was described that an acute ghrelin administration blocks food intake, GH release and normalize glucose levels during chronic caloric restriction. For this reason, it could be considered as a key endocrine factor in the regulation of systemic energy metabolism. Nevertheless, the exact mechanism of action is still un...

Introduction: Almost all type 1 diabetes mellitus (T1DM) patients have autoantibodies (ab) at disease onset. These ab prevalence varies according to patients’ age, origin and disease duration.Aim: Determine diabetes mellitus ab prevalence in a paediatric and adult T1DM Portuguese according to their age on diagnosis, gender and diabetes duration.Methods: Retrospective review of T1DM ab (glutamic acid decarboxylase 65 autoantibo...

Introduction: Maturity-Onset Diabetes of the Young (MODY) is a rare cause of Diabetes Mellitus (<5%), resulting from autosomal dominant monogenic defects.NEUROD1 gene is expressed in pancreatic and neuronal cells, being associated with MODY type 6. Mutations in NEUROD1 gene are reported in 20 families worldwide to date. Heterozygous variant c.616C>A, p.(His206Asn) has never been described.Case Report: The authors report a c...

Background: The diagnosis of hypocortisolism is challenging in hemodialysis (HD) patients due to shared clinical features between renal failure and cortisol deficiency. We hypothesize that in a significant percentage of HD patients we miss cortisol deficiency.Methods: A prospective cohort of 56 end stage kidney disease patients on maintenance HD treatment (mean age 65.3±13.1, females 80 %) was studied. Low dose (1 mg) adrenocorticotropic hormone (AC...

Cushing’s syndrome (CS) is associated with a considerable risk of complications including thromboembolic events (TE). They occur mostly within the first 2–3 months postoperatively. When present before surgery, CS has high rates of perioperative mortality and morbidity. The benefit of steroidogenesis inhibitors after TE is not fully known. Furthermore, little guidance is available regarding TE assessment/management in CS. We report a case of a 34-year-old male admitte...

It is well-known that the increase of intraprostatic levels of 5α-dihydrotestosterone is related to the development of prostatic pathologies such as benign prostatic hyperplasia and prostate cancer. So finasteride and dutasteride-based therapies have been used to improve these diseases. These drugs are potent inhibitors of the enzyme 5α-reductase, which is found in the androgen-dependent tissues. This enzyme is responsible for converting testosterone into dihydrotest...

Introduction: Medical specialization model in Spain is carried out through specialized health training, through the residency program. Residents are a key element for the proper functioning of today’s National Health System. The aim of the study is to analyze, by an anonymous survey, the opinion of three aspects among final-year residents in Endocrinology and Nutrition (E&N): self-assessment of the knowledge acquired, working prospects, care and training consequences ...
