Effect and its mechanism of Linagliptin on mild cognitive impairment in elderly type 2 diabetes mellitus patients
Bibliographic record
Abstract
Objective To investigate the effect and its underlying mechanism of Linagliptin on mild cognitive impairment(MCI)in elderly type 2 diabetes mellitus (T2DM) patients. Methods Montreal Cognitive Assessment(MoCA)scale was used to prospectively screen T2DM patients for MCI in our hospital from December 2016 to June 2017, and a total of 98 elderly T2DM patients with MCI were recruited.They were randomly divided into the linagliptin group(Linagliptin + metformin, n=50)and the non-linagliptin group(gliclazide + metformin, n=48). Serum fasting plasma glucose(FPG), glycosylated hemoglobin(HbAlc), blood lipids and amyloid β-protein 1-42(Aβ1-42)levels were determined, and MoCA score and homeostasis model assessment of insulin resistance(HOMA-IR)were calculated, and were compared between the two groups before and after 24 weeks of treatment. Results In the linagliptin group, serum FPG, HbA1c, HOMA-IR, Aβ1-42 levels were significantly decreased and MoCA score was increased after 24 weeks of treatment as compared with pre-treatment[(7.29±1.00)mmol/L vs.(9.16±1.60)mmol/L, (7.19±0.99)% vs.(9.36±1.07)%, (3.05±1.12) vs.(4.05±1.30), (0.463±0.093)g/L vs.(0.528±0.110)g/L, (24.48±1.18) vs.(23.22±1.37), all P 0.05]. It is worth to pay close attention to the key discovery of this paper that HOMA-IR and Aβ1-42 levels were significantly lower and MoCA score was significantly higher in the linagliptin group than in the non-linagliptin group after 24 weeks of treatment(all P<0.05). Conclusions Linagliptin as one of DPP-4 enzyme inhibitors can improve the cognitive function in elderly patients with T2DM, which might be relevant to reducing serum Aβ level and improving HOMA-IR.DPP-4 enzyme inhibitor may be a good option for treatment of mild cognitive dysfunction in T2DM patients in the future.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
