Inflammation and Gut Barrier Function-Related Genes and Colorectal Cancer Risk in Western European Populations.

Gut barrier dysfunction and related inflammation are known to be associated with the development and progression of colorectal cancer (CRC). We investigated associations of 292 single-nucleotide polymorphisms (SNPs) from 27 genes related to endotoxins/lipopolysaccharide (LPS) sensing and tolerance, mucin synthesis, inflammation, and Crohn's disease with colon and rectal cancer risks. Incident CRC cases (N=1,374; colon=871, rectum=503) were matched 1:1 to controls nested within the European Prospective Investigation into Cancer and Nutrition cohort.

Association of inflammation-related exposures and ovarian cancer survival in a multi-site cohort study of Black women.

Background: An association was observed between an inflammation-related risk score (IRRS) and worse overall survival (OS) among a cohort of mostly White women with invasive epithelial ovarian cancer (EOC). Herein, we evaluated the association between the IRRS and OS among Black women with EOC, a population with higher frequencies of pro-inflammatory exposures and worse survival.

Methods: The analysis included 592 Black women diagnosed with EOC from the African American Cancer Epidemiology Study (AACES).

Differential risks of changes in seizure frequency with transitions between hormonal and non-hormonal contraception in women with epilepsy: A prospective cohort study.

This prospective, observational, cohort study of 101 women with epilepsy (WWE) assesses the seizure safety of systemic hormonal contraception (HC) versus non-HC (NHC). It reports risks of changes in seizure frequency associated with transition from NHC to HC relative to HC to NHC for (1) proportions of WWE with ≥50% increase and decrease in seizure frequency, (2) changes in seizure frequency, (3) changes in seizure severity, and 4) changes in AED regimen during the study. In comparing NHC to HC versus HC to NHC, NHC to HC had greater risk of ≥50% increase in seizure frequency: RR = 1.

Vitamin D-Related Genes, Blood Vitamin D Levels and Colorectal Cancer Risk in Western European Populations.

Higher circulating 25-hydroxyvitamin D levels (25(OH)D) have been found to be associated with lower risk for colorectal cancer (CRC) in prospective studies. Whether this association is modified by genetic variation in genes related to vitamin D metabolism and action has not been well studied in humans. We investigated 1307 functional and tagging single-nucleotide polymorphisms (SNPs; individually, and by gene/pathway) in 86 vitamin D-related genes in 1420 incident CRC cases matched to controls from the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort.

Infertility, impaired fecundity, and live birth/pregnancy ratio in women with epilepsy in the USA: Findings of the Epilepsy Birth Control Registry.

Objective: To determine the current risks of infertility and impaired fecundity as well as the live birth/pregnancy ratio among women with epilepsy (WWE) in the USA and whether antiepileptic drug (AED) use is a factor.

Methods: These retrospective survey data come from the 2010-2014 Epilepsy Birth Control Registry (EBCR) Web-based survey of 1000 WWE in the USA, aged 18-47 years, who provided demographic, epilepsy, AED, reproductive, and contraceptive data. We report risks of infertility and impaired fecundity, live birth/pregnancy ratio, and whether outcomes differ by AED use or category versus No AED.

Prevalence of highly effective contraception use by women with epilepsy.

Objective: To determine (1) the proportion of women with epilepsy (WWE) at risk of unintended pregnancy who use highly effective contraception, (2) demographic predictors, and (3) folic acid (FA) use.

Methods: These cross-sectional data come from 311 US WWE, 18-47 years, who participated in the Epilepsy Birth Control Registry (EBCR) web-based survey in 2017. They provided demographic, epilepsy, antiepileptic drug (AED), contraceptive, and FA data.

Does the age of seizure onset relate to menarche and does it matter?

Purpose: To determine whether there is a relationship between the age of seizure onset and the age of menarche.

Methods: 1144 women with epilepsy (WWE) in the community, ages 18-47 years, provided web-based survey data. We compared the frequencies of the individual differences between their ages of seizure onset and menarche to each other and chance.

Effects of supplemental calcium and vitamin D on tight-junction proteins and mucin-12 expression in the normal rectal mucosa of colorectal adenoma patients.

The physical gut barrier, comprised of a thick mucus layer and the epithelium, plays an important role in defense against microbes and foreign antigens. Calcium and vitamin D may be involved in maintaining the integrity of the intestinal mucosal barrier, the dysfunction of which may lead to endotoxemia and inflammation, and contribute to colorectal carcinogenesis. We investigated supplemental calcium (1200 mg, daily) and/or vitamin D (1000 IU daily) effects on intestinal barrier function-related biomarkers in a subset of 105 participants from a large colorectal adenoma recurrence chemoprevention clinical trial.

Association of Unintended Pregnancy With Spontaneous Fetal Loss in Women With Epilepsy: Findings of the Epilepsy Birth Control Registry.

Importance: If unintended pregnancy is common among women with epilepsy and is associated with increased risk of spontaneous fetal loss (SFL), it is important to develop guidelines for safe and effective contraception for this community.

Objective: To assess whether planned pregnancy is a determinant of SFL in women with epilepsy.

Design, Setting, And Participants: The Epilepsy Birth Control Registry conducted this web-based, retrospective survey between 2010 and 2014.

Effects of Supplemental Calcium and Vitamin D on Expression of Toll-Like Receptors and Phospho-IKKα/β in the Normal Rectal Mucosa of Colorectal Adenoma Patients.

Chronic inflammation in the colorectum, a significant contributor to colorectal carcinogenesis, can be triggered by the activation of proinflammatory signaling pathways such as those initiated by Toll-like receptors (TLR) and nuclear factor κB (NF-κB). Although experimental evidence supports calcium and vitamin D potentially modifying these proinflammatory pathways in the colorectum, human data in these regards are scarce. We investigated supplemental calcium (1,200 mg daily) and/or vitamin D (1,000 IU daily) effects on inflammatory signaling pathway-related biomarkers in a subset of 105 participants from a colorectal adenoma recurrence chemoprevention clinical trial.

Folic acid use by women with epilepsy: Findings of the Epilepsy Birth Control Registry.

Purpose: To determine the prevalence and predictors of folic acid (FA) use by women with epilepsy (WWE) at risk of unintended pregnancy.

Methods: These retrospective data come from the Epilepsy Birth Control Registry (EBCR) web-based survey of 1144 WWE in the community, 18-47years, who provided demographic, epilepsy, AED, contraception, pregnancy, healthcare visits and FA data. We report prevalence and predictors of FA use in relation to risk of pregnancy (not at risk, at risk, seeking pregnancy, pregnant), demographics, seizure types and AED and contraception categories.

Reasons for discontinuation of reversible contraceptive methods by women with epilepsy.

Objective: To report the reasons for discontinuation of contraceptive methods by women with epilepsy (WWE).
