Objectives: The research aimed to provide the most recent and comprehensive analysis and evidence update comparing outcomes in neonatal encephalopathy (NE) based on different glycemia levels.

Patients And Methods: A comprehensive search of Cochrane, PubMed, Embase, Web of Science, CNKI, and Wanfang databases was conducted until September 2023. The purpose was to identify research that examined the effects of hyperglycemia, hypoglycemia, and normoglycemia on NE outcomes. The hyperglycemic, normoglycemic and hypoglycemic group were compared. Outcomes measured were mortality, abnormal MRI, hearing or visual unfavorable outcomes, neurodevelopmental delay, cerebral palsy, and all unfavorable outcomes.

Results: Thirteen literatures comprising 2,427 participants (1,233 with normoglycemia, 835 with hyperglycemia, and 359 with hypoglycemia) were considered. Pooled analysis showed more overall adverse outcomes, higher mortality and worse hearing or visual outcomes in the hyperglycemic and hypoglycemic group compared to the normoglycemic group. There was no notable distinction found in abnormal MRI and cerebral palsy among all groups. The hypoglycemic group exhibited greater neurodevelopmental delay than normoglycemia.

Conclusions: Maintaining normal blood glucose levels in neonates with NE can help reduce the risk of adverse consequences such as hearing and visual impairment.

One way to treat diabetes mellitus type II is by using α-glucosidase inhibitor, that will slow down the postprandial glucose intake. Metabolomics analysis of Artabotrys sumatranus leaf extract was used in this research to predict the active compounds as α-glucosidase inhibitors from this extract. Both multivariate statistical analysis and machine learning approaches were used to improve the confidence of the predictions.

Background: Biological sex influences Alzheimer's disease (AD) development, particularly concerning brain insulin resistance (bIR) and early energy metabolism defects. Biliverdin reductase-A (BVR-A) plays a crucial role in insulin signaling, and its downregulation leads to bIR. However, the sex-related differences in AD neuropathology and underlying mechanisms remain unclear.

Background: A drug cocktail targeting different processes of aging was tested in an aging mouse model of Alzheimer's disease (AD) neuropathologic change as an intervention to improve behaviors corresponding to cognitive dysfunction in AD.

Method: A cocktail of acarbose/rapamycin/phenylbutyrate or a control treatment was administered (medicated vs. non-medicated chow) chronically to 22 months-old mice that received viral vector injections to induce amyloid and tau pathology in the hippocampus at 24 months of age.

Background: Brain insulin resistance (bIR) heavily impacts on the core pathological processes of aging and Alzheimer disease (AD) since insulin regulates brain metabolism and cognitive functions. A close link among bIR, oxidative stress (OS) and mitochondrial defects exists, that contributes to brain dysfunctions observed in AD. Intriguingly, several studies suggest that intranasal insulin treatment (INI) enhances cognitive performance and reduced AD neuropathology both in humans and murine models of AD.

Background: Sodium glucose transporter 2 inhibitor (SGLT2i) is the latest guideline-directed medical therapy for patients with heart failure, as it has demonstrated favorable cardiovascular outcomes in heart failure (HF) patients with or without diabetes. Furthermore, SGLT2i has effectively improved cognitive function in older adults with diabetes and HF. However, the effects of SGLT2i on cognitive function and brain mitochondrial function in rats with ischemic HF have never been investigated.
