Abstract

fetched live from OpenAlex

Researchers have been actively looking to biomarker development as a way to improve diagnosis in conditions such as fetal alcohol syndrome (FAS) that have typically been difficult to identify at an early stage. Meconium testing is considered a potentially useful newborn screening method. Screening for alcohol (and other drug) use is unique from all other types of newborn screening in that there is a greater element of social risk for parents, particularly mothers (public exposure of substance use with potential for child welfare involvement). There are many factors related to the science and ethics of the meconium screening process to consider before implementing universal or targeted screening. As care providers who participate in the screening and counseling process and as advocates for infants and their families, neonatal nurses should be active participants in discussions surrounding the ethical and clinical appropriateness of meconium screening program development and expansion. The science behind meconium screening at present is not strong enough to warrant widespread implementation of screening; neonatal nurses are cautioned to approach screening carefully because of the critical social implications for mother and baby.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
