Certain features of pregnancy are important risk factors for breast cancer, such as protection afforded by young age at first birth. Preeclampsia, a pregnancy complication, is associated with reduced maternal breast cancer risk. However, questions remain regarding causality, biological mechanisms and the relation of other hypertensive conditions to risk. We conducted a population-based case-control study of breast cancer cases (n=116,196) in parous women identified through linkage of birth and cancer registries in Denmark, Finland, Norway and Sweden (1967-2013), including up to 10 matched controls per case (n=1,147,192) sampled from the birth registries (complete data were not available on all variables)...

Preeclampsia and hyperemesis gravidarum are pregnancy complications associated with altered sex hormone levels. Previous studies suggest preeclampsia may be associated with a decreased risk of subsequent breast cancer and hyperemesis with an increased risk, but the evidence remains unclear. We used data from the Generations Study, a large prospective study of women in the United Kingdom, to estimate relative risks of breast cancer in relation to a history of preeclampsia and hyperemesis using Cox regression adjusting for known breast cancer risk factors...

BACKGROUND: Preeclampsia is frequently linked to reduced breast cancer risk. However, little is known regarding the underlying genetic association and the association between preeclampsia and mammographic density. METHODS: This study estimates the incidence rate ratios (IRRs) of breast cancer in patients with preeclampsia, when compared to women without preeclampsia, using Poisson regression models in two cohorts of pregnant women: a Swedish nationwide cohort (n = 1,337,934, 1973-2011) and the Karolinska Mammography Project for Risk Prediction of Breast Cancer (KARMA, n = 55,044, 1958-2015)...

Ischaemic stroke is rare in premenopausal women but risk increases with advancing age and doubles in the ten years following the menopause. Up to the age of 75 years men have a 25% higher risk of suffering a stroke compared with women. However, the increased life expectancy of women ultimately results in a higher overall incidence. Twice as many women die from stroke compare with breast cancer. Women with cerebrovascular disease are more likely to present with atypical symptoms than men. Altered mental status (including unresponsiveness, confusion and behavioural change) is the most common nonconventional symptom, and is reported by 23% of women compared with 15% of men...

PURPOSE: Hypertension in pregnancy has been associated with decreased future risk of breast cancer in many but not all studies. In the Marin Women's Study, pregnancy-induced hypertension was shown to interact with the T allele of a functional IGF1R gene variant, rs2016347, to result in lower breast density, as well as decreased breast cancer risk. Our objective was to explore these findings in a larger sample of women from the California Teachers Study (CTS). METHODS: The CTS cohort consists of over 130,000 female educators...

BACKGROUND: Pregnancy-related hypertensive disorders, including preeclampsia (PE) and pregnancy-induced hypertension (PIH), may influence the maternal risk of breast cancer. However, results of the cohort studies were inconsistent. METHODS: An updated meta-analysis of cohort studies was performed to evaluate the association between PE, PIH and maternal breast cancer incidence. Relevant studies were identified via searching of PubMed and Embase databases. A random effect model was applied to synthesize the results...

OBJECTIVES: One of every four pregnant women in Chile is obese. Gestational obesity is associated with maternal metabolic complications in pregnancy (e.g., gestational diabetes, preeclampsia), but to our knowledge, there is little evidence on relationships with future metabolic risk. The aim of this study was to evaluate the association between prepregnancy obesity (prepregnancy body mass index ≥30 kg/m2 ) or excessive gestational weight gain (GWG; according to the 2009 recommendations from the Institute of Medicine), and maternal metabolic complications 10 y postpartum in premenopausal Chilean women...

STUDY QUESTION: Can the diagnosis of common diseases before menopause influence age at natural menopause (ANM) onset? SUMMARY ANSWER: Polycystic ovary syndrome (PCOS) and depression were observed to delay menopause. WHAT IS KNOWN ALREADY: It has been observed that women who undergo early menopause experience a higher burden of health problems related to metabolic syndromes, heart disease and depression, but whether ANM can be influenced by common adult diseases has not been studied extensively...

MicroRNAs (miRNAs) are short non-coding RNAs that act as important regulators of gene expression as part of the epigenetic machinery. In addition to posttranscriptional gene silencing by miRNAs, the epigenetic mechanisms also include DNA methylation, histone modifications and their crosstalk. Epigenetic modifications were reported to play an important role in many disease onsets and progressions and can be used to explain several features of complex diseases, such as late onset and fluctuation of symptoms. However, miRNAs not only function as a part of epigenetic machinery, but are also epigenetically modified by DNA methylation and histone modification like any other protein-coding gene...

Extracellular vesicles (EVs) are released from almost all cells and tissues. They are able to transport substances (e.g. proteins, RNA or DNA) at higher concentrations than in their environment and may adhere in a receptor-controlled manner to specific cells or tissues in order to release their content into the respective target structure. Blood contains high concentrations of EVs mainly derived from platelets, and, at a smaller amount, from erythrocytes. The female and male reproductive tracts produce EVs which may be associated with fertility or infertility and are released into body fluids and mucosas of the urogenital organs...

Preeclampsia is one of the leading causes of maternal and perinatal mortality and morbidity and its pathogenesis is not fully understood. B-cell lymphoma 6 (BCL6), a key regulator of B-lymphocyte development, is altered in preeclamptic placentas. We show here that BCL6 is present in all 3 studied trophoblast cell lines and it is predominantly expressed in trophoblastic HTR-8/SVneo cells derived from a 1(st) trimester placenta, suggestive of its involvement in trophoblast expansion in the early stage of placental development...

BACKGROUND: Reproductive factors are well-known risk factors for premenopausal breast cancer (PBC). It is unknown whether these associations are modified by familial factors, including genetic and early environment factors. METHODS: Using Swedish health registries, we performed a nested case-control study with two control groups: sister controls and population controls. The study population included women with live singleton births between 1973 and 2010, who also had a full sister who gave birth during this period...

BACKGROUND: In parous women preeclampsia has been associated with reduced risk of developing breast cancer. Characteristics of births following preeclamptic pregnancies may help understand mechanisms involved in the breast cancer risk reduction inferred by preeclampsia. METHODS: We conducted a register-based cohort study of all Danish women giving birth during 1978-2010 (n = 778,701). The association between preeclampsia and breast cancer was evaluated overall and according to birth characteristics by means of incidence rate ratios (IRR) estimated in Poisson regression models...

The traditionally recognized role of vitamin D consists in the regulation of bone metabolism and calcium-phosphorus homeostasis but recently a lot of in vitro and in vivo studies recognized several "noncalcemic" effects of vitamin D metabolites. Accumulating evidence suggests that the metabolic pathways of this vitamin may play a key role in the developing of gynaecological/obstetric diseases. VDR-mediated signalling pathways and vitamin D levels seem to (deeply) affect the risk of several gynaecological diseases, such as polycystic ovary syndrome (PCOS), endometriosis, and ovarian and even breast cancer...

We review diagnostic and predictive roles of the angiogenic proteins placental growth factor, soluble fms-like tyrosine kinase 1, and soluble endoglin in preeclampsia, and their association with future cardiovascular disease, diabetes, and breast cancer. Specific patterns of these proteins represent preeclamptic prediction markers and combined with maternal and clinical characteristics, the predictive values increase. Women experiencing preeclampsia have increased risks of developing cardiovascular diseases and diabetes, and a decreased risk of breast cancer...

Cord blood insulin-like growth factor-1 (IGF-1) concentrations are lower in preeclamptic (PE) than normotensive (NT) pregnancies. PE offspring have increased risk of cardiovascular disease and decreased risk of some cancers including breast. We examined the effects of PE exposure in utero, infant feeding and childhood diet at 3-5 years on IGF-1 and breast development in 194 female offspring who were followed from birth until follow-ups at 10.8 and 12.9 years. Diet was not associated with serum IGF-1 levels at 10...

OBJECTIVE: The purpose of this study was to compare longitudinally sampled maternal angiogenic proteins between singleton and twin pregnancies. STUDY DESIGN: Placental growth factor (PlGF), soluble feline McDonough sarcoma (fms)-like tyrosine kinase (sFlt)-1, and soluble endoglin from healthy pregnant women were quantified at 10, 18, 26, and 35 weeks' gestation (n=91), and during the third trimester (31-39 weeks) and at delivery (33-41 weeks; n=41). Geometric means and 95% confidence intervals were calculated for gestational age-adjusted angiogenic protein concentrations and compared between matched twin and singleton pregnancies...

Women born from a preeclamptic (PE) pregnancy are associated with a lower risk of breast cancer. Prenatal and early-life exposures are hypothesized to influence breast cancer susceptibility through their effect on stem cells. We examined stem cell populations in umbilical cord blood from PE pregnancies and compared with those from pregnancies without this condition. We isolated mononuclear cells from 58 PE and 197 normotensive (non-PE) umbilical cord blood samples and examined the different stem cell populations...

Cardiovascular (CV) diseases are the primary cause of death of women. Since they kill 10 times more than breast cancer, preventive measures should be implemented. According to U.S. recommendations, a woman is either at "CV risk" or at "optimal health status" if she has no risk factors and a perfectly healthy lifestyle. Some risk factors are more deleterious to women (smoking, diabetes, stress, depression, atrial fibrillation); or specific to women (preeclampsia, gestational diabetes, contraception, menopause, headaches)...
