Abstract

fetched live from OpenAlex

Alzheimer’s Disease (AD) poses a serious health concern especially for the aging population above the years of 65. An estimated 6 million Americans are diagnosed with Alzheimer’s Disease, and there are at least 50 million Alzheimer’s patients in the world. AD affects the daily life of these patients, yet there is no permanent cure. Current treatments involve cholinesterase inhibitors and NMDA-receptor agonists to help alleviate the symptoms. GLP-1 is a peptide often used in the treatment of diabetes. Since there are shared pathological features between diabetes and AD, such as insulin dysfunction and glucose metabolism dysregulation, GLP-1 may be a viable study for AD treatment. To perform a meta-analysis to investigate whether GLP-1 has a beneficiary effect on biological markers and cognitive outcome in AD patients. We searched the following electronic databases: EMBASE, MEDLINE, phycINFO, CINAHL, PubMed, Cochrane CENTRAL, and ClinicalTrials.gov. We only utilized Randomized Control Trials (RCTs) and clinical trials. We also searched with the following Medical Search Headings: Alzheimer’s Disease, Alzheimer, Alzheimer’s, and GLP-1. We included 2 randomized, double-blind, and placebo controlled clinical trials into our meta-analysis. We extracted the baseline and outcomes from the clinical trials and evaluated its risks of bias. Biological markers were measured by amyloid beta (Aß) accumulation, and cognitive outcomes were measured by the Wechsler Memory Scale - Fourth Edition (WMS-IV) and Mini Mental State Exam (MMSE). For one study, the WMS-IV was used to measure cognitive outcome. The other study measured cognitive outcome with the MMSE. Biological markers were measured by Aß accumulation in one study and with [11C]PIB tracer in another. There was no significant difference between the placebo and experimental group after the treatment period.

Teacher imitation

Not 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.
