OBJECTIVES To study vitamin B12 concentrations in patients with type 2 diabetes with and without metformin use and to identify risk factors and consequences of low vitamin B12 concentrations. RESEARCH DESIGN AND METHODS This study had a cross-sectional design. During eight weeks all patients with type 2 diabetes visiting the diabetic outpatient clinic of(More)
BACKGROUND The objective of this study was to determine whether the management of type 2 diabetes (DM2) can be transferred from an internist to a nurse specialised in diabetes (NSD). METHODS Ninety-three patients with DM2 referred by their general practitioner were randomised; 84 patients completed the study. The intervention group received care from an(More)
OBJECTIVE To identify published studies evaluating the effects of cinnamon on glycaemic control. DESIGN Literature search. METHOD The Medline database was searched using all possible combinations of the words and medical subject headings (MeSH) 'cinnamon', 'diabetes mellitus', 'HbA1C' and 'glucose'. All human or animal studies in which cinnamon was(More)
BACKGROUND Accurate blood pressure (BP) readings and correctly interpreting the obtained values are of great importance. However, there is considerable variation in the different BP measuring methods suggested in guidelines and used in hypertension trials. OBJECTIVE To compare the different methods used to measure BP; measuring once, the method used for a(More)
BACKGROUND To describe the relationship between glycaemic control, hyperglycaemic symptoms and quality of life (HRQOL) in type 2 diabetic patients. METHODS In a shared-care diabetes project HRQOL was assessed. A total of 1664 patients with type 2 diabetes were identified in 32 primary healthcare practices. Of these patients, 1149 were included. HRQOL was(More)
Since as early as the 50s of the last century, it has been known that chromium is essential for normal glucose metabolism. Too little chromium in the diet may lead to insulin resistance. However, there is still no standard against which chromium deficiency can be established. Nevertheless, chromium supplements are becoming increasingly popular. Various(More)
In the Netherlands, guidelines for the diagnosis of diabetes mellitus are confusing and differ from the international guidelines. Capillary blood-glucose testing using a blood-glucose device is allowed used as a diagnostic tool, although this test is imprecise. The Dutch laboratories measure blood-glucose concentrations by a more precise accurate method,(More)
Although blood pressure control has undoubtedly proven its benefits in reducing the high cardiovascular risk in patients with type 2 diabetes mellitus (T2DM), it still remains unclear whether intensive antihypertensive treatment in old age (> 75 years) is beneficial. Many of the current guidelines recommend a systolic blood pressure (SBP) < 140 mmHg or(More)
BACKGROUND Whether self-monitoring of blood glucose (SMBG) improves glycaemic control in patients with type 2 diabetes mellitus (T2DM) not using insulin is questionable. Our aim was to investigate the effects of SMBG in patients with T2DM who were in persistent moderate glycaemic control whilst not using insulin. METHODS Patients were eligible when(More)
