: Bisphenol A (BPA) is an industrial ubiquitous compound, frequently used to produce synthetic polymers and epoxy resins. BPA is a well-recognized endocrine disruptor and xenoestrogen compound. Evidence from epidemiological and experimental studies suggests that perinatal BPA exposure (gestation and/or lactation) increases the risk of developing various diseases, including the cardiovascular system. Developmental programming refers to environmental insults during the critical window of development that affect the structure and physiology of body systems, causing permanent changes in later stages. BPA influences the developmental programming of non-communicable diseases in the offspring. In the present review, we discuss the developmental programming of cardiovascular diseases related to perinatal exposure to BPA, supported by epidemiological and experimental evidence from published literature. The majority of the reported studies found a positive association between perinatal BPA exposure and adverse cardiovascular repercussions in the fetal, neonatal, and adulthood stages. The possible underlying mechanisms include epigenetic modifications of genes involved in cardiac muscle development, autonomic tone, collagenous and non-collagenous extracellular matrix, cardiac remodeling and calcium homeostasis, and mitochondrial energy metabolism. Epigenetics can modify the outcome of any disease. Hence, in the present review, we also discuss the role of epigenetics in preventing cardiovascular diseases following perinatal exposure to BPA. We also highlight how future treatment and drug delivery related to cardiovascular involvement could be based on epigenetic markers.

Compelling epidemiological studies suggest that birth weight is inversely associated with blood pressure. Experimental studies indicate a sex difference, with males being more susceptible to developmental insults than females. However, experimental studies suggest that ageing abolishes the sex difference, exacerbating cardiovascular risk in females.

The Relationship

AbstractPurposeEndocrine-related diseases and disorders are on the rise globally. Synthetically produced environmental chemicals (endocrine-disrupting chemicals (EDCs)) mimic hormones like oestrogen and alter signalling pathways. Endometriosis is an oestrogen-dependent condition, affecting 10–15% of women of the reproductive age, and has substantial impacts on the quality of life. The aetiology of endometriosis is believed to be multifactorial, ranging from genetic causes to immunologic dysfunction due to environmental exposure to EDCs. Hence, we undertook a systematic review and investigated the epidemiological evidence for an association between EDCs and the development of endometriosis. We also aimed to assess studies on the relationship between body concentration of EDCs and the severity of endometriosis.MethodFollowing PRISMA guidelines, a structured search of PubMed, Embase and Scopus was conducted (to July 2018). The included studies analysed the association between one or more EDCs and the prevalence of endometriosis. The types of EDCs, association and outcome, participant characteristics and confounding variables were extracted and analysed. Quality assessment was performed using standard criteria.ResultsIn total, 29 studies were included. Phthalate esters were positively associated with the prevalence of endometriosis. The majority (71%) of studies revealed a significant association between bisphenol A, organochlorinated environmental pollutants (dioxins, dioxin-like compounds, organochlorinated pesticides, polychlorinated biphenyls) and the prevalence of endometriosis. A positive association between copper, chromium and prevalence of endometriosis was demonstrated in one study only. Cadmium, lead and mercury were not associated with the prevalence of endometriosis. There were conflicting results for the association between nickel and endometriosis. The relationship of EDCs and severity of endometriosis was not established in the studies.ConclusionWe found some evidence to suggest an association between phthalate esters, bisphenol A, organochlorinated environmental pollutants and the prevalence of endometriosis. Disentangling these exposures from various other factors that affect endometriosis is complex, but an important topic for further research.

Abstract Increasing prevalence of metabolic syndrome (MetS) is causing significant health burden among the European population. Current knowledge supports the notion that endocrine disrupting chemicals (EDCs) interfere with human metabolism and hormonal balance, contributing to the conventionally recognized life-style related risk factors for MetS. In relation to the Human biomonitoring initiative (HBM4EU) five priority substances (Bisphenol A, Per- and polyfluoroalkyl substances (PFASs), Phthalates, Cadmium and Arsenic) and their association with adverse metabolic health effects were examined. A methodological framework for scoping reviews was followed to increase consistency and transparency throughout the process. A literature review was conducted to identify epidemiological studies focusing on the association between MetS or its individual components and the five HBM4EU priority substances. Human biomonitoring studies have been able to present evidence supporting EDC exposure and development of individual MetS components; however the strength of the association varies between the components and EDCs. Most of the identified literature examined Bisphenol A and Phthalate exposure, usually targeting obesity, anthropometrics or glucose metabolism. Evidence suggests a positive association between Bisphenol A and Phthalate exposure and obesity-related components. The substance group of PFASs indicated weakest association, as the results were inconsistent and were suggestive only for a positive association with development of dyslipidaemia. Current evidence on metabolic disturbances and EDCs are inconclusive and fragmented, hence establishing harmonized and standardized human biomonitoring procedures among the European population are needed. Rigorous and ongoing human biomonitoring in combination with health monitoring could provide comprehensive information on EDC exposure and association of metabolic disturbances. Key messages EDC exposure is ubiquitous within European population, hence more human biomonitoring in combination with health surveys is needed to strengthen knowledge on human’s metabolic health. MetS is an increasing global health concern, which requires novel approaches to tackle the challenge.

Background. Bisphenol A (BPA) is a common chemical used in the manufacture of polycarbonate plastics and epoxy resins, with >93% of US adults having detectable BPA levels in urine. Recent animal studies have suggested that BPA exposure may have a role in several mechanisms involved in the development of hypertension, including weight gain, insulin resistance, thyroid dysfunction, endothelial dysfunction, and oxidative stress. However, no previous human study has examined the association between markers of BPA exposure and hypertension.Methods. We examined urinary BPA levels in 1380 subjects from the National Health and Nutritional Examination Survey 2003-2004. Main outcome-of-interest was hypertension, defined as blood pressure-reducing medication use and/or blood pressures >140/90 mm of Hg (n=580).Results. We observed a positive association between increasing levels of urinary BPA and hypertension independent of confounding factors such as age, gender, race/ethnicity, smoking, body mass index (BMI), diabetes mellitus and total serum cholesterol levels. Compared to tertile 1 (referent), the multivariate-adjusted odds ratio (95% confidence interval) of hypertension associated with tertile 3 was 1.50 (1.12−2.00);P-trend = 0.007. The association was consistently present in subgroup analyses by race/ethnicity, smoking status, BMI, and diabetes mellitus.Conclusions. Urinary BPA levels are associated with hypertension, independent of traditional risk factors.

The Impact

Parasites can both influence and be affected by host population dynamics, and a growing number of case studies support a role for parasites in causing or amplifying host population cycles. In this study, we examined individual and population predictors of gastrointestinal parasitism on wild cyclic montane voles ( Microtus montanus (Peale, 1848)) to determine if evidence was consistent with theory implicating parasites in population cycles. We sampled three sites in central Colorado for the duration of a multiannual cycle and recorded the prevalence and intensity of directly transmitted Eimeria Schneider, 1875 and indirectly transmitted cestodes from a total of 267 voles. We found significant associations between host infection status, individual traits (sex, age, and reproductive status) and population variables (site, trapping period, and population density), including a positive association between host density and cestode prevalence, and a negative association between host density and Eimeria prevalence. Both cestode and Eimeria intensity correlated positively with host age, reproductive status, and population density, but neither parasite was associated with poorer host condition. Our findings suggest that parasites are common in this natural host, but determining their potential to influence montane vole cycles requires future experimental studies and long-term monitoring to determine the fitness consequences of infection and the impact of parasite removal on host dynamics.

Abstract Study question Is there an association between exposure to certain environmental toxins and the prevalence of uterine leiomyoma in women? Summary answer Some evidence was obtained to suggest an association between phthalate esters, bisphenol A, heavy metals, persistent organic pollutants and the prevalence of uterine fibroids. What is known already Environmental toxins are naturally occurring, or human made chemicals that can act as endocrine disrupting chemicals (EDCs) by binding and activating estrogen receptors in the body. Uterine fibroids, often called leiomyoma are non-cancerous growths occurring in the uterus. Though often asymptomatic, they can cause pain, infertility, pregnancy complications and are a leading cause for hysterectomy. The aetiology of leiomyoma is not fully understood but both estrogen and progesterone have been implicated in their growth. We aimed to investigate the epidemiological evidence for the association between EDCs and the prevalence of fibroids.  Study design, size, duration We undertook a systematic review and in keeping with PRISMA guidelines, a structured search of Medline, Embase, Scopus, and Web of Science was conducted (to October 2020). Case-control, cross-sectional, cohort and experimental studies were included.  Participants/materials, setting, methods The included studies analyzed the association between one or more toxins and the occurrence, or growth of leiomyoma in humans, including human cell lines. The types of toxins, patient characteristics, association and outcome, body concentration of toxin and confounding variables were extracted and analyzed. Quality assessment was performed using the Newcastle-Ottawa Scale. Main results and the role of chance In total, 34 studies were included. The majority (76%) of studies revealed a significant association between the exposure studied and the prevalence of uterine leiomyoma. In examining body burden in cases vs controls, phthalate esters showed an association with increased odds of uterine leiomyoma, except in one case where a negative association was observed. In vitro experimental studies examining the effect of alkyl-phenols such as bisphenol A (BPA), octylphenol (OP) and nonylphenol (NP) demonstrated that these environmental estrogens can act to promote the proliferation of leiomyoma cells through a number of mechanisms, typically including the estrogen receptor alpha (ERa) signalling pathway. There were conflicting results for the association between alkyl-phenols and fibroids in case-control studies. A positive association between cadmium was demonstrated in only two studies. There were conflicting results for the association between lead, mercury, arsenic and uterine fibroids. Several metabolites of organophosphate esters, alternative plasticizers, and persistent organic pollutants were associated with an increased risk of uterine fibroids.  Limitations, reasons for caution Separating these exposures from the multiple other factors that could affect the outcome of leiomyoma is challenging, but an important issue for future research.  Wider implications of the findings The link between some environmental toxins and uterine fibroids discussed is in agreement with previous literature. However, our review provides a more in depth analysis on specific dosage effects, odds ratios, and potential gene mechanisms of the exposures. This information could contribute to more accurate preventative measures. Trial registration number not applicable
