Apoptosis and necroptosis are the primary modes of eukaryotic cell death, with apoptosis being non-inflammatory while necroptosis is highly inflammatory. We previously demonstrated that, once activated, necroptosis is enhanced by hyperglycemia in several cell types. Here, we determine if hyperglycemia affects apoptosis similarly. We show that hyperglycemia does not enhance extrinsic apoptosis but potentiates a shift to RIP1-dependent necroptosis. This is due to increased levels and activity of RIP1, RIP3, and MLKL, as well as decreased levels and activity of executioner caspases under hyperglycemic conditions following stimulation of apoptosis...

Hyperglycemia in pregnancy may lead to adverse maternal, fetal and neonatal outcomes. Tight glycemic control is prudent in order to reduce pregnancy complications. For many years, the gold standard pharmacological therapy during pregnancy was human insulin. Recently, insulin analogues were also introduced to clinical use in pregnancy. This brief review aims to summarize the information on the efficacy and safety of insulin analogue therapy during gestation. The strengths and pitfalls of insulin analogue administration during gestation, compared with human insulin, are presented...

Mangiferin functions as a perfect anti-oxidative compound in the diabetic heart, however, the exact mechanism remains to be elucidated. Here, we show the cardioprotective effect of mangiferin under high glucose-induced cardiotoxic condition mainly contributed to enhanced autophagy via suppressing mTORC1 downstream signal transduction. Primary neonatal rat cardiomyocytes were cultured to detect myocytes injury, autophagy, and related signal transduction under different doses of glucose and mangiferin treatment...

Diabetes is a frequent condition in pregnancy and achieving adequate glycemic control is of paramount importance. Insulin treatment is the gold standard, oral agents are more attractive, but their safety and efficiency should be a prerequisite for their use. We have more information regarding treatment of women with gestational diabetes mellitus where glyburide can induce a picture of fetal hyperinsulinism (higher birthweight and more neonatal hypoglycemia) whereas metformin requires supplemental insulin in a larger proportion of women but achieves satisfactory perinatal outcomes with the exception of preterm birth...

Concurrent with the rise in obesity, global rates of diabetes are increasing at alarming rates in both developed and developing nations. As these conditions become more prevalent among women of reproductive age, rates of hyperglycemia in pregnancy (HIP) are also increasing. HIP is associated with many immediate perinatal complications which affect both maternal and fetal/neonatal health, as well as with more long term complications. Long term complications include an increase in chronic non-communicable diseases in both mother and offspring, therefore affecting future generations...

Neonatal hyperglycemia is common in extremely low birth weight (ELBW) infants because of physiologic stress, exogenous glucose infusion, and postnatal corticosteroid therapy for hypotension, adrenal insufficiency, and pulmonary immaturity. The use of long-acting insulin glargine has been described in the treatment of transient neonatal diabetes in the premature infant, but in these reports is a lack of regard to its use in the treatment of iatrogenic neonatal hyperglycemia. We present the case of an ELBW infant with significant hyperglycemia that was refractory to usual treatment but demonstrated a favorable response to long-acting subcutaneous insulin glargine...

BACKGROUND AND OBJECTIVE: Gestational diabetes (GDM) occurs more often in women from certain ethnic groups and is also associated with fetal macrosomia. In this study, we investigated the ability of a gestational diabetes screening test (GDS), the 2hour 75gram-Oral Glucose Tolerance Test (OGTT), and glycated hemoglobin (HbA1c) in predicting postpartum dysglycemia and fetal macrosomia in women of Caucasian, Filipino, Chinese and South-Asian descent. METHODS: 848 women diagnosed with carbohydrate intolerance in pregnancy who completed a 2hour 75g- OGTT within 6 months postpartum, were included in the study...

The diagnosis and treatment of gestational diabetes mellitus (GDM) have been in a state of flux since the World Health Organization accepted and endorsed the International Diabetes and Pregnancy Study Group's diagnostic pathway and criteria in 2013. These new diagnostic criteria identify an increasing number of women at risk of hyperglycemia in pregnancy (HGiP). Maternal hyperglycemia represents a significant risk to the mother and fetus, in both the short and long term. Controversially, metformin use for the treatment of GDM is increasing in Australia...

BACKGROUND: Treatment of hyperglycemia in women with gestational diabetes mellitus (GDM) is associated with improved maternal and neonatal outcomes and requires intensive clinical input. This is currently achieved by hospital clinic attendance every 2 to 4 weeks with limited opportunity for intervention between these visits. OBJECTIVE: We conducted a randomized controlled trial to determine whether the use of a mobile phone-based real-time blood glucose management system to manage women with GDM remotely was as effective in controlling blood glucose as standard care through clinic attendance...

AIMS: To develop a risk "engine" or calculator, integrating the risks of hyperglycemia, maternal BMI and other basic demographic data commonly available at the time of the pregnancy oral glucose tolerance test (OGTT), to predict an individual's absolute risk of specific adverse pregnancy outcomes. METHODS: Data from the Brisbane HAPO cohort was analysed using logistic regression to determine the relationship between four clinical outcomes (primary CS, birth injury, large-for-gestational age, excess neonatal adiposity) with different combinations of OGTT results and maternal demographics (age, height, BMI, parity)...

BACKGROUND: Injury severity induces a proportionate acute metabolic stress response, associated with increased risk of hyperglycemia. We hypothesized that excess caloric delivery (overfeeding) during high stress states would increase hyperglycemia and disrupt response homeostasis. METHODS: Gestational age, daily weight, total daily caloric intake, serum C-reactive protein (CRP), prealbumin, and blood glucose concentrations in all acutely-injured premature NICU infants requiring TPN over the past 3years were reviewed...

Hyperglycemia (blood glucose concentration >150 mg/dL) is common in extremely low gestational age newborns (ELGANs; birth at <28 week gestation). Hyperglycemia increases the risk of brain injury in the neonatal period. The long-term effects are not well understood. In adult rats, hyperglycemia alters hippocampal energy metabolism. The effects of hyperglycemia on the developing hippocampus were studied in rat pups. In Experiment 1, recurrent hyperglycemia of graded severity (moderate hyperglycemia (moderate-HG), mean blood glucose 214...

INTRODUCTION: Diabetes is a well-known risk factor in pregnancy. Because maternal diabetes involves oxidative stress that is also induced by chronic hypoxia and can alter vascular function, we sought to determine the effects of chronic maternal hyperglycemia on the fetoplacental vasculature in rats and to compare it with the effects of chronic hypoxia. METHODS: Diabetes was induced in female rats by a streptozotocin injection at a neonatal age. When these animals reached adulthood, their hyperglycemia was confirmed and they were inseminated...

Diabetes mellitus is associated with sensory abnormalities, including exacerbated responses to painful (hyperalgesia) or non-painful (allodynia) stimuli. These abnormalities are symptoms of diabetic peripheral neuropathy (DPN), which is the most common complication that affects approximately 50% of diabetic patients. Yet, the underlying mechanisms linking hyperglycemia and symptoms of DPN remain poorly understood. The transient receptor potential vanilloid 1 (TRPV1) channel plays a central role in such sensory abnormalities and shows elevated expression levels in animal models of diabetes...
