Objective: A reliable form of androgen substitution therapy in terms of favorable kinetics and tolerance as well as effective restoration of androgenicity is paramount in hypogonadal men. A new feasible modality is the intramuscular injection of the long-acting ester testosterone undecanoate (TU).Design: Analysis of safety data accumulated during 101 treatment-years in 66 hypogonadal men receiving altogether 510 injections of 1000 mg TU in 10–14-we...

A 30 year old woman presented at 15 weeks gestation with resistant hypertension (that had been diagnosed prior to pregnancy) and hypokalaemia (2.8 mmol/l). Subsequent tests, whilst on Nifedipine, showed a markedly raised aldosterone/renin ratio of 267 (n<25) [Aldosterone 720 ng/L;Renin 3 mu/L] (Aldosterone reference range: Supine:20–190 ng/L, Ambulant 30–340 ng/L; Renin reference range: Supine 2–30 mu/L, Ambulant 3–40 mu/L).<p class="a...

Introduction: Obesity, a chronic disease, is recognised as a major public health problem. In 2023, the National Institute for Health and Care Excellence (NICE) recommended semaglutide, a weekly glucagon-like peptide-1 (GLP-1) agonist, as a pharmacological option for weight management. This case series aims to evaluate the real-world effectiveness and safety profile of semaglutide therapy for weight loss.Methods: Retrospe...

Introduction: The prevalence of obesity, a chronic disease with significant morbidity, has rapidly increased in recent decades. Semaglutide, an injectable glucagon-like peptide-1 agonist, has gained global popularity after its approval for weight management in 2021. All studies have reported marked variability in semaglutide response, with a small proportion of patients (10-16%) showing inadequate response. Data about the predictors of poor response to semaglutide for weight l...

A 73-year-old independent female presented with reduced consciousness following a tonic-clonic seizure. Investigations revealed acute hyponatraemia, with a serum sodium of 103 mmol/l. Cortisol reserve and thyroid function was normal and the biochemical diagnosis was consistent with SiADH. A CT brain scan was normal. Hypertonic saline was commenced with empirical anti-viral and antibiotic therapy. Lumbar puncture revealed a slightly elevated CSF protein and her EEG showed non-s...

Hypercalcemia in hyperthyroidism is usually asymptomatic, and related to a concurrent primary hyperparathyroidism. In this report, we describe a case of symptomatic hypercalcemia secondary to Graves’ disease alone.Case report: A 24-year-old Filipino female presented to the emergency department with generalized weakness, vomiting and abdominal pain. No other symptoms were noted. She was otherwise previously healthy. Family history was unremarkable. D...

Introduction: The production of an oocyte competent of fertilisation and normal embryonic development is controlled by a series of highly organised signals and intracellular events which are known to be affected by physiological glucocorticoids. The actions of these adrenal steroids are modulated by 11β-hydroxysteroid dehydrogenase (11β-HSD) enzymes and we have recently reported that 11β-HSD activity in porcine oocytes increases 20-fold during meiotic maturation...

Type 2 diabetes (T2D) affects 1 in 15 people in the U.K, ischaemic damage is predominant and caused by hypoxia. The physiological response to hypoxia is an increase in the transcription factor hypoxia inducible factor (HIF)-1α, which results in reduced oxygen consuming. Previously we have demonstrated that the diabetic heart fails to respond to hypoxia and the aim of this work was to determine if a similar effect was seen in the kidney. HEK293T cells were incubated for 8h...

AZP-3601, a long-acting PTH/PTHrP(1-36) analog, is a candidate new treatment option for hypoparathyroidism (HP). As compared to conventional PTH(1-34), AZP-3601 binds with higher affinity to the R0 conformation of the PTH-1 receptor, resulting in prolonged signaling and sustained elevations in blood calcium (Ca++) in vivo, despite a very short circulating half-life. We assessed whether repeated injection of AZP-3601 into TPTX rats at doses aimed to normalize serum C...
