Background
Gestational diabetes mellitus (GDM) is a temporary form of diabetes during pregnancy, which influences the health of maternal-child in clinical practice. It is still urgent to develop new effective treatment for GDM. Naringenin is a bioactive ingredient with multiple activities including anti-diabetic. In current study, the effects of naringenin on GDM symptoms, insulin tolerance, inflammation, and productive outcomes were evaluated and the underlying mechanisms were explored.
Methods
We administrated naringenin to GDM mice and monitored the GDM symptoms, glucose and insulin tolerance, inflammation and productive outcomes. We established tumor necrosis factor alpha (TNF-α)-induced insulin resistance skeletal muscle cell model and evaluated the effects of naringenin on reactive oxygen species (ROS) production, glucose uptake and glucose transporter type 4 (GLUT4) membrane translocation.
Results
We found that naringenin ameliorated GDM symptoms, improved glucose and insulin tolerance, inhibited inflammation, and improved productive outcomes. It was further found that naringenin inhibited TNF-α-induced ROS production, enhanced GLUT4 membrane translocation, and glucose uptake, which were abolished by inhibition of AMP-activated protein kinase (AMPK).
Conclusion
Naringenin improves insulin sensitivity in gestational diabetes mellitus mice in an AMPK-dependent manner.
ObjectiveTo evaluate the accuracy of glycosylated hemoglobin A1c (HbA1c) for the diagnosis of postpartum abnormal glucose tolerance among women with gestational diabetes mellitus (GDM).MethodsAfter a systematic review of related studies, the sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and other measures about the accuracy of HbA1c in the diagnosis of postpartum abnormal glucose tolerance were pooled using random-effects models. The summary receiver operating characteristic (SROC) curve was used to summarize the overall test performance.ResultsSix studies met our inclusion criteria. The pooled results on SEN, SPE, PLR, NLR, and DOR were 0.36 (95% CI 0.23–0.52), 0.85 (95% CI 0.73–0.92), 2.4 (95% CI 1.6–3.6), 0.75 (95% CI 0.63–0.88) and 3 (95% CI 2–5). The area under the summary receiver operating characteristic (SROC) curve was 0.67 with a Q value of 0.63.ConclusionsMeasurement of HbA1c alone is not a sensitive test to detect abnormal glucose tolerance in women with prior GDM.
Background: Liraglutide has been shown to improve glucose tolerance and lose weight in individuals with type 2 diabetes. To date, no meta-analysis of liraglutide’s safety and efficacy in individuals without diabetes has been conducted.Objectives: The aim of this study is to carry out a meta-analysis to assess the efficacy and safety of liraglutide in the obese, non-diabetic individuals.Methods: A literature review was performed to identify all published randomised control trials (RCT) of liraglutide for the treatment of obesity in non-diabetic individuals. The search included the following databases: EMBASE, MEDLINE and the Cochrane Controlled Trials Register.Results: We included five publications involving a total of 4,754 patients that compared liraglutide with placebo and found that liraglutide to be an effective and safe treatment for weight loss in individuals without diabetes. Primary efficacy end points: mean weight loss (MD = -5.52, 95% CI = -5.93 to -5.11, p<0.00001); lost more than 5% of body weight (OR = 5.46, 95% CI=3.57 to 8.34, p<0.00001) and key secondary efficacy end points: SBP decreased (the MD = -2.56, 95% CI = -3.28 to -1.84, p<0.00001). Safety assessments included the proportion of individuals who were withdrawn due to AE (OR = 2.85, 95% CI= 0.84 to 9.62, p=0.009), and nausea indicated that liraglutide was well tolerated. Conclusion: This systematic review and meta-analysis indicates that liraglutide to be an effective and safe treatment for weight loss in the obese, non-diabetic individuals.Keywords: liraglutide, weight loss, meta-analysis.
The purpose of the study was to examine how behavioural inhibition was associated with shyness and social competence and how maternal parenting moderated the associations in urban Chinese children. Participants were 2-year-old toddlers (N = 286, 143 boys and 143 girls) and their mothers in P. R. China. Data on behavioural inhibition were collected from laboratory observations. Mothers completed measures of parenting and child shyness and competence. It was found that behavioural inhibition was positively associated with shyness and negatively associated with social competence for children with low maternal support, but not for children with high maternal support, suggesting that maternal support might serve as a protective factor that buffered against the maladaptive development of inhibited children. The results indicate the functional meaning of early childhood inhibition and the role of parenting in today's urban China.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
