Abstract
BACKGROUND: Persons with bipolar disorder are often overweight and cluster risk factors for cardiovascular disease. Some antibipolar agents adversely impact upon weight and the lipid milieu. Recent data suggest that valproic acid, a commonly prescribed mood stabilizer, may be associated with polycystic ovarian syndrome (PCOS). This adverse event has not been systematically studied in bipolar disorder. METHOD: Thirty-eight female subjects, aged 18-50 years, meeting DSM-IV criteria for bipolar I or II disorder, in any phase of illness were evaluated. Eighteen females received valproate (sodium valproate and valproic acid) and 20 females received lithium. Patients completed questions regarding their menstrual, reproductive and medical histories. During the follicular phase they were assessed for weight, body mass index (BMI kg/m2), and changes in the reproductive endocrine milieu that included morning estradiol, progesterone, follicle-stimulating hormone (FSH), luteinizing hormone (LH), sex-hormone binding globulin (SHBG), androstenedione, dehydroepiandrosterone-sulfate (DHEAS), testosterone, free testosterone, prolactin and thyroid-stimulating hormone (TSH). The blood was also analyzed for fasting metabolic parameters which included total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), insulin, glycosylated hemoglobin (HbA1C), insulin-like growth factor 1 (IGF-1), insulin-like growth factor binding-protein 1 (IGFBP-1), fasting blood glucose and morning leptin. RESULTS: Nine (50%) of the valproate-treated females had menstrual abnormalities versus three (15%) of the lithium-treated females (p < 0.05). Valproate-treated females had significantly higher levels of follicular phase androgen concentrations than lithium-treated females (p < 0.05). Nine (50%) of females who were overweight (BMI > or = 25 kg/m2) and with a history of menstrual irregularities also exhibited laboratory evidence of hyperandrogenism (p < 0.05). Persons receiving valproate exhibited significant increases in fasting biochemical parameters suggestive of an adverse metabolic syndrome (p < 0.05). Leptin levels were significantly elevated in the valproate-treated females (p < 0.05). CONCLUSIONS: In this pilot, open-label cross-sectional study, valproate-treated females exhibited higher rates of menstrual abnormalities and biochemical evidence of both hyperandrogenism and adverse metabolic parameters when compared with lithium-treated females. These preliminary data suggest that valproate may, in some predisposed females, adversely impact upon the reproductive endocrine milieu and result in aspects of the metabolic syndrome.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
