Objective: To investigate the correlation between transcription factor 7-like 2 (TCF7L2) gene polymorphisms and gestational diabetes mellitus (GDM) risk in the central Chinese population.
Methods: This case-control study examined the association of seven gene single-nucleotide polymorphisms (SNPs) (rs11196218, rs4506565, rs7895340, rs7901695, rs11196205, rs12243326, and rs290487) with GDM risk in the central Chinese population (843 GDM and 877 controls). The clinical information and blood samples were collected by trained interviewers and nurses. Genotyping of SNPs was conducted on the Sequenom MassARRAY platform. Statistical analyses including -test, ANOVA, chi-square test, Fisher's exact test, and logistic regression were performed.
Results: Differences in age, pre-pregnant body mass index (BMI), and family history of type 2 diabetes mellitus (T2DM) between the case and control groups were significant ( < 0.05). Compared with the wild-type genotype, pregnant women with genotypes of rs4506565-AT ( = 1.89, 95%: 1.18-3.02), rs7895340 GA ( = 1.93, 95%: 1.06-3.54), rs7901695-TC ( = 1.79, 95%: 1.11-2.88), and rs11196205-GC ( = 2.15, 95%: 1.16-3.98) had a significantly higher risk of GDM, adjusted by age, pre-pregnant BMI, and family history of T2DM. Functional annotation showed that all these four SNPs fell in the functional elements of human pancreatic islets. Further cumulative effects analysis concluded that when participants carried all these four risk genotypes, the risk of GDM was 3.51 times ( = 3.51, 95%: 1.38-8.90) than that of those without any risk genotypes.
Conclusions: The findings of this study suggested that rs4506565, rs7895340, rs7901695, and rs11196205 were the genetic susceptibility SNPs of GDM in the central Chinese population. Further studies are needed to validate our findings and clarify the underlying mechanisms.

Background: Liraglutide is a glucagon-like peptide-1 (GLP-1) analogue licensed for the treatment of type 2 diabetes mellitus (T2DM). Preclinical evidence in transgenic models of Alzheimer's disease suggests that liraglutide exerts neuroprotective effects by reducing amyloid oligomers, normalising synaptic plasticity and cerebral glucose uptake, and increasing the proliferation of neuronal progenitor cells.
Method: This is a multi-centre, randomised, double-blind, placebo-controlled, phase IIb trial of liraglutide in participants with mild to moderate Alzheimer's dementia, conducted at several centres in the UK.

Background: Epidemiological studies report an elevated risk of neurodegenerative disorders, particularly Parkinson's disease (PD), in patients with type 2 diabetes mellitus (T2DM) that is mitigated in those prescribed incretin mimetics or dipeptidyl peptidase 4 inhibitors (DPP-4Is). Incretin mimetic repurposing appears promising in human PD and Alzheimer's disease (AD) clinical trials. DPP-4Is are yet to be evaluated in PD or AD human studies.

Background: Individuals with type 2 diabetes mellitus (T2DM) face an increased risk of dementia. Recent discoveries indicate that SGLT2 inhibitors, a newer class of anti-diabetic medication, exhibit beneficial metabolic effects beyond glucose control, offering a potential avenue for mitigating the risk of Alzheimer's disease (AD). However, limited evidence exists regarding whether the use of SGLT2 inhibitors effectively reduces the risk of AD.

Background: The progression of diabetes mellitus (DM) has been associated with changes in brain structure and function, often referred to as "diabetic encephalopathy," which is characterized by cognitive and neurochemical dysfunction, and identifiable structural changes in brain imaging. This study investigated the effect of Moringa leaf-supplemented diets (MLSD) on cognition, acetylcholinesterase (AChE), adenosine deaminase (ADA) and arginase activities, reactive oxygen species (ROS), total-thiol (T-SH), inflammatory cytokines (TNF-α, NF-κB, IL-6, and IL-10) levels, caspase-3 expression, and nuclear factor erythroid 2-related factor-2 (Nrf2) levels in the brain of DM rats treated with 25 mg/kg bwt acarbose (ACA).
Method: The normal control (NC) rats and diabetic rats were grouped as follows: NC rats, untreated DM rats, DM rats plus ACA, DM rats plus ACA and 2% MLSD, and DM rats plus ACA and 4% MLSD.
Background: It is more ideal to manage dementia patients in memory clinics but not all of them are referred to such clinics. Also, the characteristics of these patients are less studied and local published data is limited. In 2004, the Neuro-cognitive Clinic of Alice Ho Miu Ling Nethersole Hospital was established.
