AIMS/HYPOTHESIS: Obesity and dysglycaemia are major risk factors for type 2 diabetes. We determined if obese people undergoing laparoscopic adjustable gastric banding (LAGB) had a reduced risk of progressing from impaired fasting glucose (IFG) to diabetes. METHODS: This was a retrospective cohort study of obese people with IFG who underwent LAGB. Weight and diabetes outcomes after a minimum ...

OBJECTIVE To assess blood pressure (BP) control, antihypertensive treatment, and prevalence of resistant hypertension (RH) in patients with type 1 diabetes stratified by stage of diabetic nephropathy. RESEARCH DESIGN AND METHODS This cross-sectional study included a nationally representative cohort of patients with type 1 diabetes (N = 3,678) from the Finnish Diabetic Nephropathy Study (FinnDia...

AIMS/HYPOTHESIS: Lipolytic breakdown of endogenous lipid pools in pancreatic beta cells contributes to glucose-stimulated insulin secretion (GSIS) and is thought to be mediated by acute activation of neutral lipases in the amplification pathway. Recently it has been shown in other cell types that endogenous lipid can be metabolised by autophagy, and this lipophagy is catalysed by lysosomal aci...

AIMS/HYPOTHESIS: The relationships between smoking and glycaemic variables have not been well explored. We compared HbA1c, fasting plasma glucose (FPG) and 2 h plasma glucose (2H-PG) in current, ex- and never-smokers. METHODS: This meta-analysis used individual data from 16,886 men and 18,539 women without known diabetes in 12 DETECT-2 consortium studies and in the French Data from an Epidem...

AIMS/HYPOTHESIS: While it is well known that diet-induced obesity causes insulin resistance, the precise mechanisms underpinning the initiation of insulin resistance are unclear. To determine factors that may cause insulin resistance, we have performed a detailed time-course study in mice fed a high-fat diet (HFD). METHODS: C57Bl/6 mice were fed chow or an HFD from 3 days to 16 weeks and gluco...

AIMS/HYPOTHESIS: The small, highly conserved vasoactive peptide urotensin II (UII) is upregulated in atherosclerosis. However, its effects in diabetes-associated atherosclerosis have not been assessed. METHODS: Endothelial cells were grown in normal- and high-glucose (5 and 25 mmol/l) media with and without UII (10(-8) mol/l) and/or the UII receptor antagonist, SB-657510 (10(-8) mol/l). Apoe k...

AIMS/HYPOTHESIS: This study aimed to investigate whether variation in long-term glycaemia in type 1 diabetes as measured by HbA1c variability is associated with the cumulative incidence and risk of retinopathy requiring laser treatment. METHODS: The effect of HbA1c variability was assessed in 2,019 Finnish Diabetic Nephropathy (FinnDiane) study patients. The patients were studied in two partia...

AIMS/HYPOTHESIS: Brown adipose tissue (BAT) activation increases energy consumption and may help in the treatment of obesity. Cold exposure is the main physiological stimulus for BAT thermogenesis and the sympathetic nervous system, which innervates BAT, is essential in this process. However, cold-induced BAT activation is impaired in obese humans. To explore the therapeutic potential of BAT, i...

OBJECTIVE: Atrial fibrillation (AF) is a condition where platelet hyperaggregability is commonly present. We examined potential physiological bases for platelet hyperaggregability in a cohort of patients with acute and chronic AF. In particular, we sought to identify the impact of inflammation [myeloperoxidase (MPO) and C-reactive protein (CRP)] and impaired nitric oxide (NO) signaling. MET...

OBJECTIVES: This study estimates type 2 diabetes (T2DM) incidence in Samoans aged 25-64 years from sequential, irregularly spaced, cross-sectional population prevalence surveys. METHODS: T2DM prevalence from eight population surveys conducted over 1978-2013 (n = 12,516) was adjusted for census region, sex, and 5-year age group to the nearest previous census. Annual T2DM incidence was cal...

BACKGROUND: Methyl-dependent regulation of transcription has expanded from a traditional focus on histones to encompass transcription factor modulation. While the Set7 lysine methyltransferase is associated with pro-inflammatory gene expression in vascular endothelial cells, genome-wide regulatory roles remain to be investigated. From initial characterization of Set7 as specific for methyl-l...

OBJECTIVE: This study aimed to examine the association between change in employment participation for a 12-month period and quality of life among individuals with colorectal cancer compared with general population controls. METHODS: This was a prospective, registry-based study that enrolled middle-aged (45-64 years) residents of Queensland, Australia, who were in the paid workforce, and ...

OBJECTIVES: Few studies have measured the physical activity levels of non-Hodgkin lymphoma (NHL) survivors, and no previous studies have measured sedentary behavior levels in this population. This study used accelerometers to measure the physical activity and sedentary time levels of NHL survivors and examined the demographic, behavioral, and medical correlates of these behaviors. METHODS: ...

OBJECTIVE: Evidence suggests that TV viewing is associated with body mass index (BMI) and metabolic syndrome (MetS) in adolescents. However, it is unclear whether dietary intake mediates these relationships. METHODS: A cross-sectional analysis was conducted in adolescents (12-19 years) participating in the 2003-2006 United States National Health and Nutrition Examination Survey. BMI z sc...

OBJECTIVE: The objective of this study was to examine the cross-sectional relationship between the expression of norepinephrine transporter (NET), the protein responsible for neuronal uptake-1, and indices of glycaemia and hyperinsulinaemia, in overweight and obese individuals. METHODS: Thirteen non-medicated, non-smoking subjects, aged 58 ± 1 years (mean ± standard error of the mean), b...

OBJECTIVE: Because sympathetic nervous system activity plays a detrimental role in metabolic and cardiovascular health, this study compared the effects of a centrally acting sympatholytic agent, the effects of a weight loss (WL) program using a low-calorie diet, and the effects of a combination of both. METHODS: Young (18-30 years) male subjects with overweight (BMI > 25 kg/m2 ) were all...

OBJECTIVE: To examine the change in use of hypnotics and/or sedatives after gastric bypass surgery or intensive lifestyle modification in adults with obesity. METHODS: Adults with obesity who underwent gastric bypass surgery or initiated intensive lifestyle modification between 2007 and 2012 were identified through the Scandinavian Obesity Surgery Registry and a Swedish commercial weight...

OBJECTIVE: Examine the mediating role of diet in the relationship between volume and duration of sedentary time with cardiometabolic health in adolescents. METHODS: Adolescents (12-19 years) participating in the 2003/04 and 2005/06 U.S. National Health and Nutrition Examination Survey (NHANES) were examined. Cardiometabolic health indicators were body mass index z-scores (zBMI) (n = 1,79...

OBJECTIVE: To analyze trends in the prevalence of overweight and obesity among Mongolian adults during the past decade as measured by body mass index (BMI) and waist circumference (WC). METHODS: Data from the repeated cross-sectional surveys on the prevalence of noncommunicable disease risk factors conducted in 2005, 2009, and 2013 in Mongolia were used. Linear regression was used to qua...

OBJECTIVE: Alterations in lipids in muscle and plasma have been documented in insulin-resistant people with obesity. Whether these lipid alterations are a reflection of insulin resistance or obesity remains unclear. METHODS: Nondiabetic sedentary individuals not treated with lipid-lowering medications were studied (n = 51). Subjects with body mass index (BMI) > 25 kg/m(2) (n = 28) were strat...
