“BACKGROUND: Previous hemorrhage, deep venous drainage, and deep location are established risk factors for arteriovenous malformation (AVM) hemorrhage. Although pregnancy is an assumed risk factor, there is a relative paucity of data to support this neurosurgical tenet.
OBJECTIVE: To elucidate the hemorrhage rate of AVMs during
pregnancy.
METHODS: We reviewed the records of 54 women with an angiographic diagnosis of an AVM at our institution. Annual hemorrhage rates were calculated as the ratio of the number of bleeds to total number of patient-years of follow-up. Patient-years of follow-up were tallied assuming lesion presence from birth until AVM obliteration. The Cox proportional hazards model for hemorrhage with pregnancy as the time-dependent variable was used to calculate the hazard ratio.
RESULTS: Five hemorrhages in 4 patients occurred over GKT137831 purchase 62 pregnancies, yielding a hemorrhage rate of 8.1% per pregnancy or 10.8% per year. Over the remaining 2461.3 patient-years of follow-up, only 28
hemorrhages occurred, yielding an annual hemorrhage rate of 1.1%. The hazard ratio for hemorrhage during pregnancy was 7.91 (P = 2.23 x 10(-4)), increasing to 18.12 (P = 7.31 x 10(-5)) when limiting the analysis to patient follow-up up to age 40.
CONCLUSION: Because of the increased risk of hemorrhage from AVMs during pregnancy, we recommend intervention in women who desire to bear children, particularly if the AVM has bled. If the AVM is discovered during pregnancy, we recommend early intervention if it has ruptured; if it is unruptured, we recommend comprehensive counseling,
weighing risks of intervention against continuation of pregnancy without intervention.”
“For the greater part of human history, political behaviors, values, preferences, and institutions have been viewed as socially determined. Discoveries during the 1970s that identified genetic influences on political orientations see more remained unaddressed. However, over the past decade, an unprecedented amount of scholarship utilizing genetic models to expand the understanding of political traits has emerged. Here, we review the ‘genetics of politics’, focusing on the topics that have received the most attention: attitudes, ideologies, and pro-social political traits, including voting behavior and participation. The emergence of this research has sparked a broad paradigm shift in the study of political behaviors toward the inclusion of biological influences and recognition of the mutual co-dependence between genes and environment in forming political behaviors.”
“Background: Arterial stiffness (AS) is associated, and a predictor of, outcome in patients with cardiovascular and renal disease.
Aim: In this study, we estimated glomerular filtration rate (eGFR) and measured indices of AS in patients with suspected coronary artery disease (CAD), and assessed their predictive value on outcome.
Design: Prospective cohort study.
