To compare the antiepileptic drug (AED) treatment patterns, seizure control, and folic acid supplementation between planned and unplanned pregnancy in women with epilepsy (WWE) and to investigate the effects of planned pregnancy on fetal outcomes. Methods: A prospectively collected database including WWE with pregnancy from Feb 2010 to Dec 2018 was retrospectively analyzed. Planned pregnancy was defined as WWE being regularly supervised by epileptologists from the time of intended pregnancy until delivery. Clinical characteristics and fetal outcomes were compared between the planned and unplanned pregnancy groups. Logistic regression was used to identify modifiable factors associated with adverse fetal outcomes. Results: A total of 188 planned pregnancies and 289 unplanned pregnancies were enrolled in our study. Among planned pregnancies, 66.0 % took AED monotherapy, and 32.4 % received polytherapy. Among unplanned pregnancies, 58.1 % didn't take AEDs, 28.0 % took monotherapy, and 12.8 % received polytherapy. The planned pregnancies had less generalized tonic-clonic seizures (P = 0.002) and higher proportion of being seizure-free (41.0 % vs. 22.8 %; P < 0.001). All planned pregnancies took folic acid while 39.8 % of unplanned pregnancies never took it (P < 0.001). The planned pregnancies had less rates of induced abortions (2.7 % vs. 13.5 %; P < 0.001), preterm births (3.3 % vs. 20.4 %; P < 0.001), and major congenital malformations (1.6 % vs. 7.5 %; P = 0.016). Pregnancy planning was independently associated with adverse fetal outcomes (adjusted OR, 0.14; 95 % CI, 0.08−0.27; P < 0.001). Conclusion:Planned pregnancy in WWE contributes to more optimized AED pattern, better seizure control, more appropriate folic acid supplementation, and less adverse fetal outcomes.

CHRNA4 may be a novel gene causing of PKD and GEFS+. Our study extends the genotypic-phenotypic spectrum of combined epileptic and dyskinetic syndromes, and provides a genetic linkage between PKD and GEFS+.

Gliomas are brain and spinal cord malignancies characterized by high malignancy, high recurrence and poor prognosis, the underlying mechanisms of which remain largely elusive. Here, we found that the Sry-related high mobility group box (Sox) family transcription factor, Sox9, was upregulated and correlated with poor prognosis of clinical gliomas. Sox9 promotes migration and invasion of glioma cells and in vivo development of xenograft tumors from inoculated glioma cells. Sox9 functions downstream of the transforming growth factor-β (TGF-β) pathway, in which TGF-β signaling prevent proteasomal degradation of the Sox9 protein in glioma cells. These findings provide novel insight into the wide interplay between TGF-β signaling and oncogenic transcription factors, and have implications for targeted therapy and prognostic assessment of gliomas.
