There is limited evidence on the effect of potassium (K+) supplementation on endothelial function. Three studies suggest a beneficial effect in healthy volunteers and mild hypertensives. However potassium increases aldosterone due to a direct effect on the adrenal gland and there is evidence that aldosterone excess is detrimental to cardiovascular health. We therefore aimed to determine the effect of potassium supplementation on endothelial function in patients with >10% c...

Background: Many young people have inadequate follow up because they lose contact with adult care following transfer from paediatrics. There is a need to adapt communication interventions to help young people to determine and enact their preferred involvement in consultations with health professionals.Objective: To develop interventions to support communication with young people in endocrine care and to assess the feasibility of implementation in routine...

Introduction: Although menstrual irregularity, including oligomenorrhea (OM), is associated with insulin resistance and hyperandrogenism, the relationship between the severity of menstrual infrequency and clinical phenotypes in young women with OM is unclear. We evaluated whether a longer menstrual cycle length is associated with less favorable metabolic features in young women.Methods/design: A total of 1296 young women (aged 15–39 years old) with ...

Background: The GH-IGF system plays an important role in strength gain. Some studies suggest that Zinc, Magnesium and Pyridoxine (ZMA) supplementation could increase GH/IGF and testosterone levels in young subjects. This hypothetical increase could lead to significant changes in body composition. ZMA is a very popular supplement, easily found in specialty stores, and it is presumed to increase GH, IGF-I and testosterone levels. However, studies are divergent regarding its effi...

Clinicians know that adolescence is a very difficult time to support young people in managing their diabetes. Studies, including the DCCT, consistently show that the average HbA1c of this age group is significantly higher than in any other age group. This talk aims to explore the possible reasons for this consistent finding and highlight how normal adolescent development can explain much of this variation. By understanding the young peoples’ needs, management plans can be...

Long bone fractures are quite common in teenagers during rapid growth, due to the lag between longitudinal growth and cortical consolidation and trabecular structure. Vertebral fractures are uncommon in young people, and should always raise concern. A low trauma fracture is defined as a fall from standing height or less, but it is important to take a good history of the mechanism of fracture, and any previous fractures. Family history is important too....

Aims: HDL have many diverse functions. The goal of this study was to determine the differential effect of HDL cholesterol (HDL-C) and apolipoprotein A-I (apoA-I) on the development of type 2 diabetes (T2D). In addition, this study determined the association between the ratio of HDL-C to apoA-I (HA) and incident T2D.Methods: A total of 27 988 subjects with impaired fasting glucose (IFG) (18 266 men and 9722 women) aged 21 to 91 years (mean age 43.5 years)...

Background: Radioiodine (RI) treatment of benign thyroid disease in young people has received a lot of attention recently with authorities in the US highlighting an encouraging short and medium term safety record. In this audit we surveyed treatment centres in the UK to assess the trend in RI administration in patients aged 21 years and under.Methods: Over sixty Medical Physics Departments, dispersed to represent a suitable geographical coverage pattern ...

Animal and observational studies suggest that the IGF axis is involved in the pathogenesis of ischemic stroke; moreover, endogenous IGF-I could influence the evolution of ischemic stroke in humans and thereby contribute to an improved clinical and functional outcome. To assess and correlate the IGF-I axis with biochemical parameters in young patients experiencing ischemic stroke (32 aged 15–45 years,19F, BMI: 25.5±3.4 kg/m2), we evaluated IGF-I, IGFBP-3, A...

Introduction: Cyclooxygenase-2 (COX-2), an inducible enzyme in prostaglandin synthesis, plays a major role in the pathogenesis of sporadic colorectal carcinoma (CRC). COX-2 inhibitors reduce the mortality from sporadic CRC. Acromegaly is associated with an increased risk of CRC, with a preponderance of right sided disease, but COX-2 protein is reduced or absent in acromegalic normal and malignant colonic mucosa. The mechanisms responsible for this are unknown.Aims: (i) To ...
