We conducted a three-stage genetic study to identify susceptibility loci for type 2 diabetes (T2D) in east Asian populations. We followed our stage 1 meta-analysis of eight T2D genome-wide association studies (6,952 cases with T2D and 11,865 controls) with a stage 2 in silico replication analysis (5,843 cases and 4,574 controls) and a stage 3 de novo(More)
IMPORTANCE Controlling glycemia, blood pressure, and cholesterol is important for patients with diabetes. How best to achieve this goal is unknown. OBJECTIVE To compare Roux-en-Y gastric bypass with lifestyle and intensive medical management to achieve control of comorbid risk factors. DESIGN, SETTING, AND PARTICIPANTS A 12-month, 2-group unblinded(More)
To investigate the underlying mechanisms of T2D pathogenesis, we looked for diabetes susceptibility genes that increase the risk of type 2 diabetes (T2D) in a Han Chinese population. A two-stage genome-wide association (GWA) study was conducted, in which 995 patients and 894 controls were genotyped using the Illumina HumanHap550-Duo BeadChip for the first(More)
OBJECTIVE Genetic polymorphisms of the transcription factor 7-like 2 (TCF7L2) gene is one of the few validated genetic variants with large effects on the risk of type 2 diabetes in the populations of European ancestry. In this study, we aimed to explore the effect of the TCF7L2 polymorphisms in a Han Chinese population. RESEARCH DESIGN AND METHODS We(More)
OBJECTIVE Genetic variants in the fat mass and obesity-associated (FTO) gene have been linked with obesity and type 2 diabetes in European populations. We aimed to test the role of FTO genetic variants in obesity and type 2 diabetes in the Chinese population. RESEARCH DESIGN AND METHODS We genotyped 19 single-nucleotide polymorphisms (SNPs) spanning from(More)
Diabetes mellitus (DM) in adults is a global health problem, although its prevalence varies widely between different populations and the rate has generally increased worldwide. In Taiwan, the mortality rate from DM has almost doubled over the past 10 years. The prevalence of DM in Taiwan was established between 1985 and 1996 and the rates were between 4.9(More)
AIM To evaluate annual prevalence and incidence of Type 2 diabetes and to examine possible trends among adults in Taiwan. METHODS A retrospective nationwide longitudinal study using the Taiwan National Health Insurance Research Database collected during 1999-2004. Adult patients aged > or = 20 years old with prevalent and incident Type 2 diabetes were(More)
BACKGROUND Preclinical and observational studies raise the concern about the safety of insulin glargine in terms of cancer initiation and promotion. This study is designed to examine cancer incidence associated with use of insulin glargine vs. intermediate/long-acting human insulin (HI). METHODOLOGY A retrospective cohort study using the Taiwan National(More)
BACKGROUND Conventional treatments for patients with type 2 diabetes are often inadequate. We aimed to assess outcomes of diabetes control and treatment risks 2 years after adding Roux-en-Y gastric bypass to intensive lifestyle and medical management. METHODS We report 2-year outcomes of a 5-year randomised trial (the Diabetes Surgery Study) at four(More)
OBJECTIVES To determine the efficacies of 2 weight-reducing operations on diabetic control and the role of duodenum exclusion. DESIGN Double-blind randomized controlled trial. SETTING Department of Surgery of the Min-Sheng General Hospital, National Taiwan University. PATIENTS We studied 60 moderately obese patients (body mass index >25 and <35) aged(More)
