The long-term microvascular complications of diabetes are a significant cause of morbidity and predict mortality in diabetic patients. Multiple pathways have been implicated in the pathogenesis of each of these complications. Evolving evidence suggests that early intervention may have long-term benefits in preventing development and reversing these chronic complications.A major limitation in the approach to dealing with the microvascular complications is...

Objective: To define the prevalence of Diabetic Peripheral Neuropathy (DPN), painful diabetic neuropathy (PDN) and the at risk diabetic foot in 2 out of the 3 National Diabetes Centres in Qatar.Methods: 712 people with Type-1 & Type-2 diabetes recruited from Alwakra Hospital and Hamad General Hospital underwent assessment for DPN & PDN using the Neurothesiometer and the DN4 questionnaire, respectively.Results: The average a...

Introduction: IGF-I and its binding proteins may modulate cardiovascular risk. As part of our Manchester Mothers’ Cardiovascular study, we tested in pre-menopausal women the hypothesis that higher circulating IGF-I concentrations would be associated with lesser arterial stiffness and lower cardiac (LV) mass, while higher IGFBP1, reflecting less pre-hepatic insulin, would be positively related to small vessel function.Methods: About 193 women aged 32...

A male in his 40’s diagnosed with type 2 diabetes in 2011 (BMI:20.7kg/m2) was admitted with DKA (Dec 2018) after a period of poor glycaemic control on oral hypoglycaemic agents (Feb 2017: HbA1c-105mmol/mol, Nov 2018: HbA1c-115mmol/mol). There was dramatic improvement in glycaemic control after commencing him on subcutaneous insulin (April 2019: HbA1c-56mmol/mol). GAD65 antibodies were positive (24u/mL; normal<5u/mL) and a diagnosis of latent autoimmune diab...

Background: Male sexual dysfunction is common in obesity with complex underlying mechanisms. Testosterone replacement has often been initiated in clinical practice in the presence of sexual dysfunction and male obesity-associated secondary hypogonadism. The benefits to sexual functioning, however, are not well documented. The aims of the study were to investigate the relationship between sexual function and hypogonadism in severe obesity and to understand the impact of bariatr...

Background: Emerging evidence suggests that impaired high density lipoprotein (HDL) function is associated with cardiovascular disease (CVD). HDL is essential for removing excess circulating cholesterol by reverse cholesterol transport (RCT). Additionally HDL reduces inflammation and oxidative stress, especially through paraoxonase-1. Whereas HDL’s capacity to accept cholesterol from peripheral cells is key (i.e. cholesterol efflux capacity (CEC)), successful RCT depends ...

Background: Obesity is a major modifiable risk factor for cardiovascular disease. Bariatric surgery is considered to be the most effective treatment option for weight reduction in obese patients with and without type 2 diabetes.Aims: To evaluate changes in lipoproteins, insulin resistance, mediators of systemic and vascular inflammation and endothelial dysfunction following Roux-en-Y bariatric surgery in obese patients with a...
