Poor Tolerability of a Transdermal Nicotine Treatment in Parkinson's Disease
Bibliographic record
Abstract
Studies assessing the effect of transdermal nicotine in Parkinson's disease (PD) have generated mixed results regarding its efficacy to treat motor and cognitive deficits. These studies generally reported good tolerability in nonsmoking PD patients. The authors report the tolerability data of an open trial with transdermal nicotine in PD. Twenty-two therapeutically well-controlled nonsmoking PD patients received a transdermal nicotine treatment over 25 days according to the following fixed titration schedule: 7 mg for the first 11 days, 14 mg for the next 11 days, and 21 mg for the last 3 days. Fourteen PD patients (64%) had side effects such as nausea, vomiting, and dizziness, and 10 of them withdrew from the study. Factors such as age, body mass index, disease duration, and motor disability were not related to this intolerance. Transdermal nicotine can produce unpleasant adverse effects in patients with PD. Given that similar doses of nicotine were better tolerated in previous studies, the authors suspect the pharmacokinetic profile of the transdermal delivery system to be a determining factor in the effect of nicotine treatment in PD.

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.
