Acquired Hypoaldosteronism may be caused by low circulating aldosterone levels (AD), resistance to mineralocorticoid action (MR), or a combination of both (CB). We describe the clinical/biochemical characteristics of these three types of hypoaldosteronism. Methods Retrospective review of a series of 177 patients with acquired hypoaldosteronism assessed by the Endocrinology Department of a tertiary teaching hospital from 2012 to 201...

Influence of Diabesity in the visceral adipose tissue miRNA expression profile.Background: The term diabesity arose in 2001 to refer to the coexistence of obesity (OB) and type 2 diabetes (T2D). It is estimated that 89% of adults diagnosed with T2D have a BMI greater than 25 kg/m2, and of them, 45% are obese. However, the mechanisms because why some obese patients develop T2D and other do not, are still unclear.Objective...

Background: the treatment of individuals with type 1 diabetes (T1D) has significantly evolved in recent years. Therefore, with the aim of achieving glycaemic targets to prevent or slow down the progression of the disease and its complications, hybrid closed-loop systems (AID) have been developed. These systems integrate three components: a continuous real-time glucose monitor, a control algorithm and an insulin pump. The objective of this study is to analyse the glycaemic and ...

Background: Complications of excess weight (CEW) clinics were commissioned by NHSE in 2021 to be leaders in the field of paediatric obesity using innovative models to deliver the highest quality patient care. Technological approaches offer a widely accessible tool which could potentially complement current clinical models of care. This study aims to explore children and young peoples (CYP) views on whether digital technology could/should be used to enhance CEW...

Polycystic ovary syndrome (PCOS) is an endocrine and metabolic disorder affecting women of reproductive age. The main features of PCOS are hyperandrogenism and reproductive and metabolic dysfunctions. We have previously shown that muscle contractions induced by either electrical stimulations or exercise act through partially similar signaling pathways in the muscle to induce glucose uptake in the acute response. Long-term electrical stimulations decrease circulating testostero...

Background: Women with polycystic ovary syndrome (PCOS) have lower health related quality of life (HRQL) and more symptoms of anxiety and depression than women without PCOS, where a higher BMI is positively correlated to both lower HRQL and more symptoms of anxiety and depression. Studies on women with PCOS and severe obesity regarding symptoms of anxiety and depression are lacking.Aims: To examine if women with severe obesity and PCOS have lower HRQL an...

Continuous administration of 400 μg/day of letrozole (LET), a non-steroidal inhibitor of P450 aromatase, with start pre-pubertally to female rats, induces hyperandrogenemia and reproductive abnormalities similar to those observed in women with polycystic ovary syndrome (PCOS). However, these rats do not develop metabolic abnormalities, despite high circulating testosterone. A possible explanation may be that the dose was too high and thus completely inhibited the estrogen...

Both low-frequency electro-acupuncture (EA) and manual acupuncture improve menstrual frequency and decrease circulating androgens in women with polycystic ovary syndrome (PCOS). We sought to determine whether low-frequency EA is more effective than manual stimulation in regulating disturbed estrous cyclicity in rats with PCOS induced by 5α-dihydrotestosterone (DHT). To identify the central mechanisms of the effects of stimulation, we assessed hypothalamic mRNA expression ...

Introduction: Neonatal events may contribute to the development of disorders such as type 2 diabetes and obesity at adult age. We have previously shown that neonatal testosterone (T) programming of female rats is followed by insulin resistance and changes in adipose tissue distribution with centralization of body fat. Therefore, the aim of this study was to examine the effects of neonatal injection of T, estradiol (E) or dihydrotestosterone (DHT) on insulin sensitivity and siz...

E R Simpson, Prince Henry's Institute, Clayton, Victoria, Australia. AbstractDr Evan Simpson is a native of Edinburgh, Scotland. He has had a long interest in the basic biology of estrogen biosynthesis, especially its relationship to breast cancer.His group was the first to clone and characterize the aromatase gene and to show the unique use of tissue-specific promoters to regulate tissue-specif...
