Background: Digital health interventions have potential to contribute to better health outcomes, better healthcare and lower costs. However, evidence for their effectiveness is variable. The development and content of digital health interventions are often not described in enough detail to enable others to replicate the research or improve on previous interventions.

Background: Evidence on how to implement new interventions into complex healthcare environments is often poorly reported and indexed, reducing its potential to inform initiatives to improve healthcare services. Using the implementation of a digital intervention within routine National Health Service (NHS) practice, we provide an example of how to develop a theoretically based implementation plan and how to report it transparently. In doing so we also highlight some of the challenges to implementation in routine healthcare.

Background: Type 2 diabetes mellitus is one of the most common long-term conditions, and costs health services approximately 10% of their total budget. Active self-management by patients improves outcomes and reduces health service costs. While the existing evidence suggested that uptake of self-management education was low, the development of internet-based technology might improve the situation.

Background: The prevalence of type 2 diabetes is increasing globally, and health services in many countries are struggling with the morbidity, mortality, and costs associated with the complications of this long-term condition. Diabetes self-management education (DSME) and behavioral support can reduce the risks of developing diabetes-related complications and improve glycemic control. However, their uptake is low.

Objective: To determine the effectiveness of a web-based self-management programme for people with type 2 diabetes in improving glycaemic control and reducing diabetes-related distress.

Methods And Design: Individually randomised two-arm controlled trial.

Setting: 21 general practices in England.

Sitagliptin, a modern antidiabetic agent which is weight neutral and associated with low rate of hypoglycaemias, is being increasingly used in type 2 diabetes mellitus (DM). However, there is a paucity of data about its efficacy and safety in beta-thalassaemia major (β-TM). This retrospective case series of five patients (mean age of 45 years) is the first study evaluating the use of sitagliptin in patients with β-TM and DM.

Background: Type 2 Diabetes Mellitus (T2DM) is common, affecting nearly 400 million people worldwide. Achieving good health for people with T2DM requires active self-management; however, uptake of self-management education is poor, and there is an urgent need to find better, more acceptable, cost-effective methods of providing self-management support. Web-based self-management support has many potential benefits for patients and health services.

Purpose: Hyponatraemia is associated with significant morbidity and mortality. The objectives of this study were to evaluate the investigation and management of hyponatraemia and to assess the use of different therapeutic modalities and their effectiveness in routine practice.

Study Design: This multicentre, retrospective, observational study was conducted at three acute NHS Trusts in March 2013.

Objective: Structured patient education programs can reduce the risk of diabetes-related complications. However, people appear to have difficulties attending face-to-face education and alternatives are needed. This review looked at the impact of computer-based diabetes self-management interventions on health status, cardiovascular risk factors, and quality of life of adults with type 2 diabetes.

Low bone mass, a major cause of morbidity in patients with β-thalassemia major (β-TM), is multifactorial. There is lack of data about the current prevalence of low bone mass in patients with β-TM. The aims of this study are to examine the current prevalence of low bone mass in β-TM patients and the association between demographic characteristics, markers of iron overload, endocrinopathies, glycemic status and bone mineral density (BMD) as well as to study the 25-OH-vitamin D status of the patients and its relationship with BMD.

Diabetes is a significant complication of β-thalassemia major (β-TM) and most patients receive fragmented diabetes care. In 2005, we developed a unique Joint Diabetes Thalassaemia Clinic, based at the Department of Diabetes, Whittington Health, London, UK, where patients were reviewed jointly by a multidisciplinary team, including Consultant Diabetologist and Hematologist. Study of the Joint Diabetes Thalassaemia Clinic (2005-2009) showed improvement in glycemic control with fructosamine reduction from 344 umol/L to 319 umol/L over a 1-year period as well as improvement in lipid profiles.

Article Synopsis
  • Endocrinopathies, such as hypogonadism and diabetes mellitus, are commonly found in patients with β thalassemia major (TM) due to iron overload from repeated blood transfusions.
  • A study of 92 patients analyzed various factors, including iron load measurements and demographic data, to identify risk factors for these endocrinopathies.
  • Results indicated that lower myocardial T2* values and higher serum ferritin levels were significantly associated with the development of these conditions, with older age also being a contributing factor.

The purpose of this study was to test the extent that constructs from two theoretical models (self-regulatory theory and social cognitive theory) mediated change in outcomes following a self-management intervention. One hundred and twenty four individuals with type 2 diabetes who had participated in a randomised controlled trial of a diabetes self-management programme were analysed for the extent that illness beliefs and self-efficacy mediated change in self-management behaviours and illness specific quality of life. Exercise specific self-efficacy significantly mediated change in exercise at three months (B = .

Background: Diabetes is one of the commonest chronic medical conditions, affecting around 347 million adults worldwide. Structured patient education programmes reduce the risk of diabetes-related complications four-fold. Internet-based self-management programmes have been shown to be effective for a number of long-term conditions, but it is unclear what are the essential or effective components of such programmes.

Self-management has been described as the cornerstone of care for diabetes. Many self-management studies are limited by poor methodology and poor descriptions of the intervention. The current study developed a theoretically based self-management programme for patients with type 2 diabetes, which was evaluated via a randomized controlled trial.

Objective: To compare the effectiveness of a nurse-led hypertension clinic with conventional community care in general practice in the management of uncontrolled hypertension in patients with type 2 diabetes.

Research Design And Methods: We studied 120 men and women outpatient attendees (61% non-Caucasian) with type 2 diabetes and a seated blood pressure (BP) >or=140/80 mmHg. All patients were being treated for hypertension, and 71% had increased urinary albumin excretion (UAE).

Background And Purpose: Although neuropsychological symptoms and signs are common in thyroid disease, their organic substrate is unknown. We performed brain MR imaging in patients with hyperthyroidism or hypothyroidism before and after treatment and correlated the results with hormonal markers.

Methods: Eight patients with hyperthyroid disease and three with hypothyroid disease underwent imaging within 1-2 days of a thyroid hormone testing.
