“Objective.— We evaluated the influence of physician-diagnosed migraine on blood pressure levels and the risk of hypertensive disorders of pregnancy in a clinic-based prospective

cohort study of 3373 healthy pregnant women. Background.— The relationship between migraine and blood pressure is controversial with results from several studies suggesting Nivolumab price positive associations, while others suggest null or inverse associations. To our knowledge, no previous study has investigated blood pressure profiles among pregnant migraineurs. Methods.— We abstracted blood pressure values and delivery information from medical records of women presenting to prenatal clinics in Washington State. Mean blood pressure differences for pregnant migraineurs and non-migraineurs were estimated in regression models, using generalized estimating equations. We calculated odds ratios and 95% confidence intervals (95% CIs) for gestational hypertension and preeclampsia in relation to migraine status. Results.— Mean first, second, and third trimester systolic blood pressures (SBP) were elevated among pregnant migraineurs as compared with non-migraineurs. Migraineurs had higher mean third trimester

SBP (4.08 mmHg) than non-migraineurs. GSK3 inhibitor Trimester-specific diastolic blood pressure (DBP) values were variably related with migraine status. Mean first (0.82 mmHg) and third (2.39 mmHg) trimester DBP were higher, and second trimester DBP values were lower (−0.24) among migraineurs as compared with non-migraineurs. Migraineurs had a 1.53-fold increased odds of preeclampsia (95% CI 1.09 to 2.16). Additionally, migraineurs who were overweight or obese had a 6.10-fold

increased odds of preeclampsia (95% CI 3.83 to 9.75) as compared with lean non-migraineurs. Conclusions.— Pregnant migraineurs had elevated blood pressures, particularly SBP measured in the third trimester, and a higher risk of preeclampsia than pregnant women without migraine. Observed associations were medchemexpress more pronounced among overweight or obese migraineurs. Our findings add to the accumulating evidence of adverse pregnancy outcomes among migraineurs. “
“During the 14th International Headache Congress the results of several innovative studies that contribute to our understanding of headache pathophysiology and treatment were presented. Here we summarize work expected to contribute substantially to understanding headache mechanisms, while an accompanying manuscript summarizes presentations regarding the treatment of headache.
