Intensive glycemic control (IGC) targeting HbA1c fails to show an unequivocal reduction of macrovascular complications in type 2 diabetes (T2D), however the underlining mechanisms remain elusive. Epigenetic changes are emerging as important mediators of cardiovascular damage and may play a role in this setting. This study investigates whether epigenetic regulation of the adaptor protein p66(Shc), a key driver of mitochondrial oxidative stress, contributes to persistent vascular dysfunction in T2D patients despite IGC...

AIMS: To explore whether a quantitative approach to identifying hospitalized patients with diabetes at risk of hypoglycaemia would be feasible through incorporation of routine biochemical, haematological and prescription data. METHODS: A retrospective cross-sectional analysis of all diabetic admissions (n=9584) from 1 January 2014 to 31 December 2014 was performed. Hypoglycaemia was defined as a blood glucose level of <4 mmol/l. The prediction model was constructed using multivariable logistic regression, populated by clinically important variables and routine laboratory data...

Oral hypoglycemic drugs for type 2 diabetes aim at preventing the metabolic effects of hyperglycemia and cardiovascular (CV) events. The evidence of the possible CV risk related to the prescription of some antidiabetic drugs prompted regulatory agencies to require safety studies. This review provides an updated analysis of CV safety profiles for antidiabetic drugs used for the treatment of patients with high CV risk.The most recent studies analyze different aspects of CV morbidity, such as ischemic events, heart failure and arrhythmia, and their interactions with hyperglycemia...

The purpose of the present study was to test if one bout of moderate exercise performed in either the fasted or the postprandial state affects glucose values measured over 22 hours. Twelve participants diagnosed with hyperglycemia not using antidiabetic medications underwent 3 test days in a randomized cross-over design encompassing one test day without exercise, one test day with 60 min of treadmill walking prior to breakfast, and one test day with an identical bout of exercise 30 min after the start of breakfast...

Photoperiod duration can be predicted from previous days but irradiance fluctuates in an unpredictable manner. To investigate how allocation to starch responds to changes in these two environmental variables, Arabidopsis Col-0 was grown in a 6-h and a 12-h photoperiod at three different irradiances. The absolute rate of starch accumulation increased when photoperiod duration was shortened and when irradiance was increased. The proportion of photosynthate allocated to starch increased strongly when photoperiod duration was decreased but only slightly when irradiance was decreased...

BACKGROUND AND PURPOSE: Spontaneous visual recovery is rare after cortical blindness. While visual rehabilitation may improve performance, no visual therapy has been widely adopted, as clinical outcomes are variable and rarely translate into improvements in activities of daily living (ADLs). We explored the potential value of a novel rehabilitation approach "cognitive therapeutic exercises" for cortical blindness. CASE DESCRIPTION: The subject of this case study was 48-year-old woman with cortical blindness and tetraplegia after cardiac arrest...

BACKGROUND: Weight gain is associated with deterioration in metabolic health, whereas weight loss improves insulin sensitivity. This study assesses the impact of long-term, successfully maintained weight loss and weight-loss relapse on measures of insulin sensitivity and identifies factors that explain variability in insulin sensitivity. METHODS: Women (20-45 years) were recruited into four groups: reduced-overweight/obese (RED, n=15); body mass index (BMI)-matched controls (stable low-weight, n=19), BMI⩽27 kg m(-2); relapsed-overweight/obese subjects (REL, n=11); and BMI-matched controls (obese stable weight, n=11), BMI⩾27 kg m(-2)...

BACKGROUND: Diabetes alert dogs (DADs) are growing in popularity as an alternative method of glucose monitoring for individuals with type 1 diabetes (T1D). Only a few empirical studies have assessed DAD accuracy, with inconsistent results. The present study examined DAD accuracy and variability in performance in real-world conditions using a convenience sample of owner-report diaries. METHOD: Eighteen DAD owners (44.4% female; 77.8% youth) with T1D completed diaries of DAD alerts during the first year after placement...

BACKGROUND: Continuous glucose monitoring (CGM) devices measure interstitial glucose concentrations (normally every 5 minutes), allowing observation of glucose variability (GV) patterns during the whole day. This information could be used to improve prescription of treatments and of insulin dosages for people suffering diabetes. Previous efforts have been focused on proposing indices of GV either in time or glucose domains, while the frequency domain has been explored only partially. The aim of this work is to explore the CGM signal in the frequency domain to understand if new indexes or features could be identified and contribute to a better characterization of glucose variability...

Objective To investigate the relationship between patient characteristics and morning glycemic variability. Methods We retrospectively evaluated 106 patients with type 2 diabetes who underwent continuous glucose monitoring during admission. The highest postprandial glucose level (within 3 hours after breakfast; 'highest level'), the time from the start of breakfast to the highest postprandial glucose level ('highest time'), the difference between the pre-breakfast and highest postprandial breakfast glucose level ('increase'), the area under the curve (AUC; ≥180 mg/dL) for the glycemic variability within 3 hours after breakfast ('morning AUC'), and the post-breakfast glucose gradient ('gradient') were calculated...

BACKGROUND AND OBJECTIVES: Ultra-long-acting insulin degludec (DEG) has a longer duration of action and less daily variability relative to other basal insulin (BI), and thus may benefit patients with type 1 diabetes mellitus (T1DM). We examined the impact of switching BI to DEG on glycemic control and insulin dose in T1DM. METHODS: T1DM patients (n = 22; six male; mean age: 64.5 ± 12.6 years) receiving basal-bolus insulin therapy were included. Initially, the BI dose was replaced with DEG in a 1:1 ratio; 80-100% of the total dose was replaced with DEG for multiple basal insulin injections...

Non-alcoholic fatty liver (NAFL) is an independent risk factor for the development of type 2 diabetes (T2DM). We examined metabolic perturbations in people with NAFL, patients with T2DM and people with normal intrahepatic lipid (IHL) (CON). A 2-step (10mU/m(2)/min, 40mU/m(2)/min) hyperinsulinemic-euglycemic clamp was performed in 11 NAFL, 13 T2DM and 11 CON, all matched for BMI and aerobic fitness. IHL was measured using proton magnetic resonance spectroscopy. Because of high IHL variability in T2DM patients, this group was separated into a high IHL (IHL≥5...
