Neuropsychiatric Symptoms, Omega-3, and Mercury Exposure in Freshwater Fish-Eaters
Bibliographic record
Abstract
Mercury is a neurotoxin, absorbed primarily through fish consumption. However, the nutritional benefit from omega-3 fatty acids (n-3 FA) may offset the deleterious effects of mercury. Increased n-3 FA have been associated with lower rates of mood disorders. The authors examined neuropsychiatric symptoms among 243 freshwater fish-eaters, with low serum n-3 FA (median = 0.11 mg/mL) and low mercury exposure (median in blood and hair = 2.22 and 0.54 microg/g). They assessed neuropsychiatric symptoms with the Brief Symptom Inventory. The results did not show the expected inverse association between serum n-3 FA and neuropsychiatric symptoms. For men who consumed more than 130 g of alcohol per week, the authors observed a positive association between serum n-3 FA and neuropsychiatric symptoms, possibly reflecting an alcohol-related release of n-3 FA from membranes into blood. They observed a positive relation between hair mercury and neuropsychiatric symptoms solely for women, suggesting that men may respond differently to mercury.

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.
