SIGNIFICANCE: Obesity and type 2 diabetes mellitus are increasing globally. There is also increasing associated complications, such as non-alcoholic fatty liver disease (NAFLD) and vascular complications of diabetes. There is currently no licensed treatment for NAFLD and no recent treatments for diabetic complications. New approaches are required, particularly addressing mechanism-based risk factors for health decline and disease progression. Recent advances: Dicarbonyl stress is the abnormal accumulation of reactive dicarbonyl metabolites such as methylglyoxal leading to cell and tissue dysfunction...

There is a wide variety of commercial bread types and the present study identifies potential pitfalls in consumer evaluations of bread from a health perspective. The aim is to describe consumers' health-related perceptions of bread by exploring which health-related quality attributes consumers associate with bread and whether there are differences with regard to age, gender and education level. A postal and web-based sequential mixed-mode survey (n = 1134, 63% responded online and 37% by paper) with open-ended questions and an elicitation task with pictures of commercial breads were used...

Traumatic brain injury is the number one cause of death and disability among the pediatric population in the USA. The heterogeneity of the pediatric population is reflected by both the normal cerebral maturation and the age differences in the causes of TBI, which generate unique age-related pathophysiology responses and recovery profiles. This review will address the normal changes in cerebral glucose metabolism throughout developmental phases and how TBI alters glucose metabolism. Evidence has shown that TBI disrupts the biochemical processing of glucose to energy...

Clear health benefits are associated with intensive glucose control in type 1 diabetes mellitus (T1DM). However, maintaining near-normal glycemia remains an elusive goal for many patients, in large part owing to the risk of severe hypoglycemia. In fact, recurrent episodes of hypoglycemia lead to 'hypoglycemia-associated autonomic failure' (HAAF), characterized by defective counter-regulatory responses to hypoglycemia. Extensive studies to understand the mechanisms underlying HAAF have revealed multiple potential etiologies, suggesting various approaches to prevent the development of HAAF...

OBJECTIVE: The increasing importance of peers in adolescence and emerging adulthood has been widely acknowledged. However, longitudinal research linking the peer context to diabetes management and outcomes is scarce. The present longitudinal study in a large sample of youths with type 1 diabetes related both positive and negative peer variables to diabetes outcomes over a time interval of 1 year. RESEARCH DESIGN AND METHODS: Our sample consisted of 467 adolescents (14-17 years of age) and emerging adults (18-25 years of age) with type 1 diabetes who participated in a two-wave longitudinal study...

Metabolic syndrome is a major risk factor for the development of cardiovascular diseases and diabetes, among other conditions. Studies have shown that aging and metabolic syndrome share several metabolic alterations, and that aged individuals, in particular females, are at an increased risk of developing metabolic disorders. Although several studies have investigated the effects of hypercaloric diets in the development of obesity and metabolic syndrome in young animals, few studies have investigated these parameters in aged animals, especially in females...

OBJECTIVE: Nuclear factor interleukin-3 regulated (NFIL3) has been known as an important transcriptional regulator of the development and the differentiation of immune cells. Although expression of NFIL3 is regulated by nutritional cues in the liver, the role of NFIL3 in the glucose metabolism has not been extensively studied. Thus, we wanted to explore the potential role of NFIL3 in the control of hepatic glucose metabolism. MATERIALS/METHODS: Mouse primary hepatocytes were cultured to perform western blot analysis, Q-PCR and chromatin immunoprecipitation assay...

Critically ill patients show a metabolic response to injury that affects carbohydrate metabolism, causing hyperglycemia and an increase in glycemic variability that makes the critically ill patient susceptible to infection, resulting in morbidity and mortality increase. Also, severe hypoglycemia was detected as a consequence of intensive insulin treatment that provokes deleterious effects in their clinical evolution, so a correct monitoring of plasma glucose would contribute to reduce morbidity and mortality...

There is growing interest among consumers in foods for sustained energy management, and an increasing number of ingredients are emerging to address this demand. The SUSTRA™ 2434 slowly digestible carbohydrate is a blend of tapioca flour and corn starch, with the potential to provide balanced energy after a meal. The aim of the study was to characterize this starch's digestion profile in vitro (modified Englyst assay) and in vivo (intact and cecectomized rooster study), and to determine its effects on available energy, by measuring post-prandial glycemia in healthy adults (n = 14), in a randomized, double-blind, placebo-controlled, cross-over study, with two food forms: cold-pressed bar and pudding...

REVIEW
Todd Anthony Astorino, Matthew M Schubert
Increased whole-body fat oxidation (FOx) has been consistently demonstrated in response to moderate intensity continuous exercise training. Completion of high intensity interval training (HIIT) and its more intense form, sprint interval training (SIT), has also been reported to increase FOx in different populations. An explanation for this increase in FOx is primarily peripheral adaptations via improvements in mitochondrial content and function. However, studies examining changes in FOx are less common in response to HIIT or SIT than those determining increases in maximal oxygen uptake which is concerning, considering that FOx has been identified as a predictor of weight gain and glycemic control...

Diabetes mellitus induces a reduction in skeletal muscle mass and strength. Strength training is prescribed as part of treatment since it improves glycemic control and promotes increase of skeletal muscle mass. The mechanisms involved in overload-induced muscle hypertrophy elicited at the establishment of the type I diabetic state was investigated in Wistar rats. The purpose was to examine whether the overload-induced hypertrophy can counteract the hypotrophy associated to the diabetic state. The experiments were performed in oxidative (soleus) or glycolytic (EDL) muscles...

Dietary starch is required for a dry, extruded kibble; the most common diet type for domesticated felines in North America. However, the amount and source of dietary starch may affect digestibility and metabolism of other macronutrients. The objectives of this study were to evaluate the effects of 3 commercial cat diets on in vivo and in vitro energy and macronutrient digestibility, and to analyze the accuracy of the modified Atwater equation. Dietary treatments differed in their perceived glycemic response (PGR) based on ingredient composition and carbohydrate content (34...

Cardiovascular dysfunction and organ damage are hallmarks of sepsis and septic shock. Protein S-nitrosylation by nitric oxide has been described as an important modifier of protein function. We studied whether protein nitrosylation/denitrosylation would impact positively in hemodynamic parameters of septic rats. Polymicrobial sepsis was induced by cecal ligation and puncture. Female Wistar rats were treated with increasing doses of DTNB [5,5'-dithio-bis-(2-nitrobenzoic acid)] 30min before or 4 or 12h after sepsis induction...

OBJECTIVE: Ribosomal protein S6 Kinase-1 (S6K1) has been linked to resistance exercise-mediated improvements in glycemia. We hypothesized that S6K1 may also play a role in regulating glycemic control in response to endurance exercise training. METHODS: S6k1-knockout (S6K1KO) and WT mice on a 60 cal% high-fat diet were trained for 4 weeks on treadmills, metabolically phenotyped, and compared to sedentary controls. RESULTS: WT mice showed improved glucose tolerance after training...

Honey is a bee-derived supersaturated solution composed of complex contents mainly glucose, fructose, amino acids, vitamins, and minerals. Composition of honey may vary due to the difference in nectar, season, geography, and storage condition. Honey has been used since times immemorial in folk medicine and has recently been rediscovered as an excellent therapeutic agent. In the past, honey was used for a variety of ailments without knowing the scientific background and active ingredients of honey. Today, honey has been scientifically proven for its antioxidant, regulation of glycemic response, antitumor, antimicrobial, anti-inflammatory, and cardiovascular potentiating agent...

Insulin has a narrow therapeutic index, reflected in a small margin between a dose that achieves good glycemic control and one that causes hypoglycemia. Once injected, the clearance of exogenous insulin is agnostic to blood glucose, aggravating the potential to cause hypoglycemia. We sought to create a "smart" insulin, one that can alter insulin clearance and hence insulin action in response to blood glucose, mitigating risk for hypoglycemia. The approach added saccharide units to insulin, to create insulin analogs with affinity for both the insulin receptor (IR) and mannose receptor C-type 1 (MR), which functions to clear endogenous mannosylated proteins, a principle used to endow insulin analogs with glucose responsivity...
