Core Viewpoint - The article discusses the challenges and recent findings in the treatment of type 3c diabetes, emphasizing the impact of pancreatic exocrine insufficiency (PEI) on treatment efficacy and the need for individualized treatment strategies [4][5][7][15]. Group 1: Overview of Type 3c Diabetes - Type 3c diabetes is a special type of diabetes caused by pancreatic diseases such as acute/chronic pancreatitis, pancreatic tumors, cystic fibrosis, and pancreatic surgery, with a prevalence of 5%-10% in Western populations [4]. - There is currently a lack of targeted treatment guidelines for type 3c diabetes, leading to reliance on standards for type 1 and type 2 diabetes, which may not be effective [5]. Group 2: Research Findings - A landmark study by the University of Exeter evaluated the efficacy and safety of oral hypoglycemic agents in 7,084 type 3c diabetes patients, comparing them with 97,000 type 2 diabetes patients [9]. - The study found that the presence of PEI significantly reduces the effectiveness of diabetes medications, with HbA1c levels decreasing by only 9.4 mmol/mol in PEI patients compared to 12.2 mmol/mol in non-PEI patients [10][11]. Group 3: Drug Efficacy and Risks - Five classes of oral hypoglycemic agents (metformin, sulfonylureas, DPP-4 inhibitors, pioglitazone, SGLT2 inhibitors) were found to be effective, but their efficacy is diminished in patients with PEI [7][12]. - The risk of discontinuation of treatment is doubled in PEI patients (OR=2.03), indicating a need for closer monitoring [13]. Group 4: Clinical Implications - For non-PEI type 3c diabetes patients, oral hypoglycemic agents are reliable and should be prioritized [14]. - For patients with PEI, there is a need to be cautious about reduced efficacy and higher discontinuation risks, suggesting potential adjustments in treatment plans [14]. - SGLT2 inhibitors may be more suitable for PEI patients needing weight loss, while sulfonylureas may help mitigate weight gain [14]. Group 5: Significance of the Research - The findings provide crucial insights for the precise treatment of type 3c diabetes, indicating that future guidelines may need to differentiate treatment strategies based on the presence of PEI [15].

Core Viewpoint - The latest research indicates that GLP-1 receptor agonists, used for treating type 2 diabetes, may be superior to metformin in preventing dementia, potentially influencing future treatment guidelines to prioritize drugs with both glycemic control and neuroprotective effects [2][4][6]. Group 1: Research Findings - The study analyzed anonymous electronic health records from 2004 to 2024, involving 87,229 patients each on GLP-1 receptor agonists and metformin, with an average age of 58 years, all having taken the medication for at least six months [4]. - Results showed that while both drug classes had similar effects on vascular dementia, GLP-1 receptor agonists had a lower overall dementia diagnosis rate: approximately 2.5% (2,130 individuals) in the GLP-1 group versus nearly 5% (4,215 individuals) in the metformin group, indicating a relative risk reduction of about 10% [4][6]. - Specifically, the risk of Alzheimer's disease was reduced by 12% and the risk of non-vascular dementia was reduced by 25% among GLP-1 users [4][6]. Group 2: Demographic Insights - The protective effects of GLP-1 receptor agonists were consistent across all age groups but were most pronounced in individuals over 60, women, and white patients [6]. - The mortality rate during the study was about 5% for GLP-1 users compared to nearly 9% for metformin users [6]. Group 3: Mechanisms of Action - The neuroprotective effects of these drugs may stem from various mechanisms, including reducing neuroinflammation, enhancing insulin sensitivity, and improving cerebral vascular function. GLP-1 receptor agonists can cross the blood-brain barrier, directly affecting the central nervous system, unlike metformin, whose effects are primarily systemic [6][8]. - The study emphasizes the complexity of vascular dementia's pathogenesis, which includes small vessel disease and white matter lesions, making treatment through metabolic or neurodegenerative pathways challenging [8]. Group 4: Implications for Treatment - The findings suggest that GLP-1 receptor agonists could become a first-line treatment option for type 2 diabetes, considering the significant societal, familial, and economic burdens associated with diabetes-related dementia [8][9]. - The research indicates a potential paradigm shift in diabetes treatment, focusing more on preventing cognitive complications [8][9]. Group 5: Additional Research - A separate study found that semaglutide could reduce the risk of Alzheimer's disease by 40-70% among older patients with type 2 diabetes and other comorbidities [12][18]. - The study utilized a large cohort of 1,094,761 new users of anti-diabetic medications, with semaglutide users showing significantly lower rates of Alzheimer's diagnosis compared to those on other diabetes medications [12][14]. Group 6: Limitations and Future Directions - The study acknowledges limitations, including its observational design, which may not account for overdiagnosis, underdiagnosis, or unmeasured confounding factors [22]. - Further research is needed to clarify the mechanisms by which semaglutide reduces the risk of Alzheimer's disease [21][22].

Group 4: Management Strategies - A scientific lifestyle management system is crucial for controlling diabetes indicators, emphasizing a diet low in glycemic index, saturated fat, and sodium, while high in dietary fiber [18]. - Exercise recommendations include daily activity for at least 30 minutes, five days a week, with heart rates maintained at a safe level [19]. - Medication should be individualized, with metformin as the first-line treatment, and regular assessments every three months to adjust treatment plans based on HbA1c results [19]. Group 5: Diagnosis Standards - Diabetes diagnosis requires strict laboratory testing standards, including fasting blood sugar levels and glucose tolerance tests [20]. - For asymptomatic individuals, a single abnormal test is insufficient for diagnosis; confirmation through repeat testing is necessary [20]. Group 6: Conclusion - Continuous monitoring and management of blood sugar and related indicators are essential to prevent complications associated with diabetes, ensuring a healthier life [21].
