Vitamina D (25-OH-D) e memória de curto prazo em participantes de um ambulatório da memória
Bibliographic record
Abstract
Dementias are a public health problem in developing countries, evidence shows that dementias are preventable provide timely interventions in modifiable risk factors are done. Vitamin D is associated to many cognitive skills and is considered as a protective factor or even treatment of cognitive decline. Objective: To evaluate the association between blood levels of vitamin D (25-OH) and short-term memory represented by the memory section of the Montreal Cognitive Assessment test (Brazilian version) controlled by sociodemographic and health variables. Methods: Cross sectional study based on patients files with 50 years old or more, analysed trough. Poisson regression in a memory clinic from February 2015 to May 2017. Results: We studied 210 individuals with a mean age of 70.8±8.6 years old, mean vitamin D blood levels of 26.5± 9.5 ng/dL. The mean score in the MoCA test was 17.0±7.5 points and the mean memory score (0-5 points) was 1.3±1.0. In the final multivariate model, there was a positive independent association between short-term memory and vitamin D blood levels, schooling, age, female gender and hypertension. Conclusion: These findings indicate that 25-OH vitamin D blood levels are associate to short term memory and may be a prognostic or screening tool for cognitive decline and dementia.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
