Preconception care for women with diabetes can reduce the occurrence of adverse birth outcomes. We aimed to estimate the preconception care (PCC)-preventable health and cost burden of adverse birth outcomes associated with diagnosed and undiagnosed pregestational diabetes mellitus (PGDM) in the United States. Among women of reproductive age (15-44 years), we estimated age- and race/ethnicity-specific prevalence of diagnosed and undiagnosed diabetes. We applied age and race/ethnicity-specific pregnancy rates, estimates of the risk reduction from PCC for 3 adverse birth outcomes (preterm birth, major birth defects, and perinatal mortality), and lifetime medical and lost productivity costs for children with those outcomes. Using a probabilistic model, we estimated the reduction in adverse birth outcomes and costs associated with universal PCC compared with no PCC among women with PGDM. We did not assess maternal outcomes and associated costs. We estimated 2.2% of US births are to women with PGDM. Among women with diagnosed diabetes, universal PCC might avert 8397 (90% prediction interval [PI], 5252-11,449) preterm deliveries, 3725 (90% PI, 3259-4126) birth defects, and 1872 (90% PI, 1239-2415) perinatal deaths annually. Associated discounted lifetime costs averted for the affected cohort of children could be as high as $4.3 billion (90% PI, 3.4-5.1 billion) (2012 US dollars). PCC among women with undiagnosed diabetes could yield an additional $1.2 billion (90% PI, 951 million-1.4 billion) in averted cost. Results suggest a substantial health and cost burden associated with PGDM that could be prevented by universal PCC, which might offset the cost of providing such care. Published by Elsevier Inc.

Applying Aggregate Exposure Pathway and Adverse Outcome ...

EPA Pesticide Factsheets

Hazard assessment for nanomaterials often involves applying in vitro dose-response data to estimate potential health risks that arise from exposure to products that contain nanomaterials. However, much uncertainty is inherent in relating bioactivities observed in an in vitro system to the perturbations of biological mechanisms that lead to apical adverse health outcomes in living organisms. The Adverse Outcome Pathway (AOP) framework addresses this uncertainty by acting as a scaffold onto which in vitro toxicity testing and other data can be arranged to aid in the interpretation of these results in terms of biologically-relevant responses, as an AOP connects an upstream molecular initiating event (MIE) to a downstream adverse outcome. In addition to hazard assessment, risk estimation also requires reconciling in vitro concentrations sufficient to produce bioactivity with in vivo concentrations that can trigger a MIE at the relevant biological target. Such target site exposures (TSEs) can be estimated by integrating pharmacokinetic considerations with environmental and exposure factors. Environmental and exposure data have been historically scattered in various resources, such as monitoring data for air pollutants or exposure models for specific chemicals. The Aggregate Exposure Pathway (AEP) framework is introduced to organize existing knowledge concerning biologically, chemically, and physically plausible, as well as empirically supported, links between the i

Objective To analyze rates of significant adverse events and outcomes in women having a medical abortion at Planned Parenthood health centers in 2009 and 2010, and to identify changes in the rates of adverse events and outcomes between the 2 years. Methods In this database review we analyzed data from Planned Parenthood affiliates that provided medical abortion in 2009 and 2010, almost exclusively using an evidence-based buccal misoprostol regimen. We evaluated the incidence of six clinically significant adverse events (hospital admission, blood transfusion, emergency room treatment, intravenous antibiotics administration, infection, and death) and two significant outcomes (ongoing pregnancy and ectopic pregnancy diagnosed after medical abortion treatment was initiated). We calculated an overall rate as well as rates for each event and identified changes between the 2 years. Results Amongst 233,805 medical abortions provided in 2009 and 2010, significant adverse events or outcomes were reported in 1,530 cases (0.65%). There was no statistically significant difference in overall rates between years. The most common significant outcome was ongoing intrauterine pregnancy (0.50%); significant adverse events occurred in 0.16% of cases. One patient death occurred due to an undiagnosed ectopic pregnancy. Only rates for emergency room treatment and blood transfusion differed by year, and were slightly higher in 2010. Conclusion Review of this large dataset reinforces the safety of the evidence-based medical abortion regimen. PMID:23262942

Black men who have sex with men (BMSM) are a population at the intersection of two minority statuses-racial minority and sexual minority. Membership in either group, compared to white or heterosexual group membership, may increase one's risk of negative childhood and adult experiences. Baseline data from an HIV intervention efficacy trial (the Black Men Evolving Study) were used to explore the prevalence of adverse childhood experiences (ACEs) among 536 BMSM and associations between ACEs and adult mental and physical health outcomes. Overall, the prevalence of ACEs was high among this sample of BMSM with almost 90% experiencing at least one ACE. Findings revealed that ACE score was significantly associated with adult mental health (AOR = 1.21, 95% CI [1.12, 1.30]), but not with adult physical health. All ACEs were significantly associated with mental health, but only physical neglect and household substance abuse were significantly associated with physical health (AOR = 1.69, 95% CI [1.02, 2.74] and AOR = 1.57, 95% CI [1.03, 2.40], respectively). The findings support the need for interventions targeting improved adult health outcomes, particularly for minority groups, to consider the impact of early adversity on health and wellness.

The vitamin D binding protein (DBP) is the major plasma carrier for vitamin D and its metabolites, but it is also an actin scavenger, and is the precursor to the immunomodulatory protein, Gc-MAF. Two missense variants of the DBP gene - rs7041 encoding Asp432Glu and rs4588 encoding Thr436Lys - change the amino acid sequence and alter the protein function. They are common enough to generate population-wide constitutive differences in vitamin D status, based on assay of the serum metabolite, 25-hydroxyvitamin D (25OHD). Whether these variants also influence the role of vitamin D in an immunologic milieu is not known. However, the issue is relevant, given the immunomodulatory effects of DBP and the role of protracted innate immune-related inflammation in response to tissue injury or repeated infection. Indeed, DBP and vitamin D may jointly or independently contribute to a variety of adverse health outcomes unrelated to classical notions of their function in bone and mineral metabolism. This review summarizes the reports to date of associations between DBP variants, and various chronic and infectious diseases. The available information leads us to conclude that DBP variants are a significant and common genetic factor in some common disorders, and therefore, are worthy of closer attention. In view of the heightened interest in vitamin D as a public health target, well-designed studies that look simultaneously at vitamin D and its carrier in relation to genotypes and adverse health outcome should be encouraged.

Between 5% and 30% of children in high-income countries live with a substance misusing parent, the majority of which is below dependent levels. However, little is understood about the impact of nondependent parental substance misuse upon children. We searched the international literature using rigorous systematic methods to identify studies examining parental substance misuse and adverse outcomes in children. The inclusion criteria were cross-sectional, longitudinal, case-control, and cohort studies; of children aged 0-18 years whose parents are high-risk substance misusers; reporting on their health, psychological, substance use, educational, and social outcomes. We identified 36 papers (from 33 unique studies), most of which were assessed as being of medium to high methodological quality ( N= 28). Parental nondependent substance misuse was found to be associated with adversity in children, with strong evidence of an association with externalizing difficulties ( N = 7 papers, all finding an association) and substance use ( N = 23 papers, all finding an association) in adolescents and some evidence of adverse health outcomes in early childhood ( N = 6/8 papers finding an association). There is less evidence of an association between parental substance misuse and adverse educational and social outcomes. The body of evidence was largest for parental alcohol misuse, with research examining the impact of parental illicit drug use being limited. Methodological limitations restrict our ability to make causal inference. Nonetheless, the prevalence of adverse outcomes in children whose parents are nondependent substance misusers highlights the need for practitioners to intervene with this population before a parent has developed substance dependency.

The present study aims to determine the association of periodontal disease (identified early in pregnancy) and adverse pregnancy outcomes in a North Indian population.   A total of 340 primigravida women, aged 20-35 years with single live pregnancy were recruited at 14-20 weeks period of gestation from the antenatal clinic. These women had undergone periodontal examination at time of recruitment. The pregnancy outcomes were recorded. Out of 340 primigravida women, 147 (43.23%) women had gingivitis and 61 (17.94%) women had periodontitis. Periodontitis was found to be significantly associated with pre-eclampsia, intrauterine growth restriction, preterm delivery, and low birthweight with odds ratios (95% confidence interval) of 7.48 (2.72-22.42), 3.35 (1.20-9.55), 2.72 (1.30-5.68) and 3.03 (1.53-5.97), respectively. The study shows a significant association between periodontitis (but not with gingivitis) and adverse pregnancy outcomes. Maternal periodontitis is associated with an increased risk of pre-eclampsia, intrauterine growth restriction, preterm delivery and low birthweight infants. © 2012 The Authors.

Older head and neck cancer patients are at increased risk for adverse health outcomes, but little is known about which geriatric assessment associates with poor outcome. The aim is to study the association of functional or cognitive impairment, social environment and frailty with adverse health outcomes in patients with head and neck cancer. Four libraries were searched for studies reporting on an association of functional or cognitive impairment, social environment and frailty with adverse outcomes in head and neck cancer patients. Of 4158 identified citations, 31 articles were included. The mean age was ⩾60years in twelve studies (39%). Geriatric conditions were prevalent: between 40 and 50% of the included participants were functional impaired, around 50% had depressive symptoms, and around 40% did not have a partner. Functional impairment was assessed in 18 studies, two studies reported on a cognitive test, eight studies examined mood and social status was depicted by 14 studies. None of the included studies addressed frailty or objectively measured physical capacity such as hand grip strength, gait speed or balance tests. In 64% of the reported associations, a decline in functional or cognitive impairment, mood or social environment was associated with adverse outcomes. Functional and cognitive impairment, depressive symptoms and social isolation are highly prevalent in head and neck cancer patients and associate with high risk of adverse health outcomes. In the future, these measurements may guide decision-making and customize treatments, but more research is needed to further improve and firmly establish clinical usability.

Dental neglect and adverse birth outcomes: a validation and observational study.

Acharya, S; Pentapati, K C; Bhat, P V

2013-05-01

The objectives of this study were to validate the Indian translation of the Dental Neglect Scale (DNS) among a sample of parturient Indian women and to investigate dental neglect as a possible risk indicator in adverse birth outcomes. Three hundred and sixteen parturient women were administered the DNS and the Modified Dental Beliefs Scale (MDBS) and were also clinically examined for oral health status. Information regarding socio-economic status, weeks of gestation and birth weight was also collected. A gestation period of less than 37 weeks was considered as preterm and a birth weight of less than 2500 gm as 'low birth weight'. The Indian version of the DNS was found to be reliable (Cronbach's Alpha = 0.72) and valid for assessing dental neglect among the women. Factor analysis of the DNS revealed a two-factor structure accounting for 56% variance. Dental neglect was higher among those with poorer oral health status, lower socio-economic and educational status. Multinomial logistic regression showed high dental neglect and negative dental beliefs and not poor oral health, as significant risk indicators for occurrence of adverse birth outcomes. The finding of an association of adverse birth outcomes with dental neglect and beliefs, but not with poor oral health could be due to the influence of other more important general factors which had a direct bearing on birth outcomes. There is a need for further research to assess the role of behavioural factors like dental neglect as risk indicators for adverse birth outcomes. © 2012 John Wiley & Sons A/S.

The use of mobile phone applications (mHealth) to provide health education and behavioral prompts is 1 of the 12 common mHealth functions identified by the World Health Organization as innovations to strengthen health systems. Among low-income pregnant and parenting women, health education is widely recognized as a way to improve maternal and infant health outcomes, but the efficacy of written health education materials to change knowledge and behavior for this population is questionable. mHealth prompts, in contrast, is a promising alternative. A team of researchers in medicine/epidemiology, anthropology/midwifery, computer science/sensors, and community-based case management created and pilot tested a mHealth application (mHealth app) for African-American women at high risk for adverse birth outcomes. We tested the acceptability and feasibility of the interactive application among women during the reproductive stages of early and late pregnancy, postpartum, and interconception. Interview data from 14 women in the various reproductive stages revealed that most women found the mHealth messages helpful. Also, 62 Ob-Gyn physicians and nurses and 19 Family Medicine residents provided feedback. Women's responses to specific messages trended down over time. Women in the postpartum phase had the highest response rate to particular text messages, followed by those in the pregnancy phase. Responses dropped off dramatically during the interconception period. About 21% of women lost their phones. Unexpected findings were that all participants already had smartphones, women wanted messages about depression, and clinicians wanted the app to link to case management for individualized medical care. Logistical challenges to app management were limitations but are useful for consideration before scale-up.

Several earlier studies have shown the presence of more dust and allergens in carpets compared with non-carpeted floors. At the same time, adverse effects of carpeted floors on perceived indoor air quality as well as worsening of symptoms in individuals with asthma and allergies were reported. Avoiding extensive carpet use in offices, schools, kindergartens and bedrooms has therefore been recommended by several health authorities. More recently, carpet producers have argued that former assessments were obsolete and that modern rugs are unproblematic, even for those with asthma and allergies. To investigate whether the recommendation to be cautious with the use of carpets is still valid, or whether there are new data supporting that carpet flooring do not present a problem for indoor air quality and health, we have reviewed the literature on this matter. We have not found updated peer reviewed evidence that carpeted floor is unproblematic for the indoor environment. On the contrary, also more recent data support that carpets may act as a repository for pollutants which may become resuspended upon activity in the carpeted area. Also, the use of carpets is still linked to perception of reduced indoor air quality as well as adverse health effects as previously reported. To our knowledge, there are no publications that report on deposition of pollutants and adverse health outcomes associated with modern rugs. However, due to the three-dimensional structure of carpets, any carpet will to some extent act like a sink. Thus, continued caution should still be exercised when considering the use of wall-to-wall carpeted floors in schools, kindergartens and offices, as well as in children's bedrooms unless special needs indicate that carpets are preferable.

Background Adverse pregnancy outcomes are undesirable events occurring during pregnancy and childbirth in mother or child, such as Preterm Low Birth Weight (PLBW) and preeclampsia. There is growing evidence that periodontitis may be a risk factor for preterm birth even after adjusting for known risk factors. Aim 1. To determine the knowledge and attitude of pregnant females about oral health. 2. To evaluate the oral hygiene practices of pregnant females. 3. To evaluate their awareness regarding effect of oral health on adverse pregnancy outcomes. 4. To assess whether there was any significant difference from their non pregnant counter parts. 5. To evaluate whether their awareness towards dental treatment had increased after conceiving. Materials and Methods 200 pregnant and 200 non-pregnant women filled up a validated questionnaire which comprised of questions on personal data, oral hygiene knowledge, attitude, oral hygiene practices and their awareness regarding the correlation of oral health to adverse pregnancy outcomes. Statistical Analysis Analyses were conducted using SPSS for Windows (version 15.0; SPSS Inc., Chicago, IL, USA). Results The results indicate no statistically significant differences in the variables assessed in both the groups, indicating that no further knowledge had been imparted to the women after they conceived. 96% women of both groups (p>0.05) had received no knowledge from the gynaecologist regarding the impact of oral health on pregnancy outcomes. 93.9% of pregnant women, and 89.5% of non pregnant women (p>0.05) did not go for routine dental check-ups. Only 3% of pregnant women were aware of oral health having a correlation with adverse pregnancy outcomes. Conclusion In our study, pregnancy did little to change future attitudes to dental care. To provide better oral health care, more knowledge needs to be made available to the pregnant women and the medical community. PMID:26674176

This article presents an integrative review of the literature examining the relationship between racial discrimination and adverse birth outcomes. Searches for research studies published from 2009 to 2015 were conducted using PubMed, CINAHL, Scopus, PsycINFO, Web of Science, and Embase. Articles were assessed for potential inclusion using the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2009 framework. Fifteen studies met criteria for review. The majority of the studies found a significant relationship between racial discrimination and low birth weight, preterm birth, and small for gestational age. Each of the studies that examined more proximal variables related to birth outcomes such as entry into prenatal care, employment opportunities, neighborhood characteristics, or inflammatory markers found significant associations between the specific variables examined and racial discrimination. Participants in qualitative studies discussed experiences of institutional racism with regard to several components of prenatal care including access and quality of care. Racial discrimination is a significant risk factor for adverse birth outcomes. To best understand the mechanisms by which racial discrimination impacts birth outcomes, and to inform the development of effective interventions that eliminate its harmful effects on health, longitudinal research that incorporates comprehensive measures of racial discrimination is needed. Health care providers must fully acknowledge and address the psychosocial factors that impact health outcomes in minority racial/ethnic women. © 2016 by the American College of Nurse-Midwives.

Adverse health effects of non-medical cannabis use.

Hall, Wayne; Degenhardt, Louisa

2009-10-17

For over two decades, cannabis, commonly known as marijuana, has been the most widely used illicit drug by young people in high-income countries, and has recently become popular on a global scale. Epidemiological research during the past 10 years suggests that regular use of cannabis during adolescence and into adulthood can have adverse effects. Epidemiological, clinical, and laboratory studies have established an association between cannabis use and adverse outcomes. We focus on adverse health effects of greatest potential public health interest-that is, those that are most likely to occur and to affect a large number of cannabis users. The most probable adverse effects include a dependence syndrome, increased risk of motor vehicle crashes, impaired respiratory function, cardiovascular disease, and adverse effects of regular use on adolescent psychosocial development and mental health.

Kalmakis, Karen A; Chandler, Genevieve E

2015-08-01

Adverse childhood experiences (ACEs) have been associated with negative health outcomes, but the evidence has had limited application in primary care practice. The purpose of this study was to systematically review the research on associations between ACEs and adult health outcomes to inform nurse practitioners (NPs) in primary care practice. The databases PubMed, CINAHL, PsycINFO, and Social Abstracts were searched for articles published in English between 2008 and 2013 using the search term "adverse childhood experiences." Forty-two research articles were included in the synthesis. The evidence was synthesized and is reported following the preferred reporting items for systematic reviews and meta-analysis procedure (PRISMA). ACEs have been associated with health consequences including physical and psychological conditions, risk behaviors, developmental disruption, and increased healthcare utilization. Generalization of the results is limited by a majority of studies (41/42) measuring childhood adversity using self-report measures. NPs are encouraged to incorporate assessment of patients' childhood history in routine primary care and to consider the evidence that supports a relationship between ACEs and health. Although difficult, talking about patient's childhood experiences may positively influence health outcomes. ©2015 American Association of Nurse Practitioners.

Preadoption adversities and postadoption mediators of mental health and school outcomes among international, foster, and private adoptees in the United States.

Adopted children are a heterogeneous group, varying along numerous factors, including type of adoption (international, foster, private), length of exposure to preadoption adversities as indexed by age of adoption, history of preadoption maltreatment, and prenatal substance exposure. Yet, we know little about how these adversity factors are mediated by quality of postadoption parent-child relationships and/or the presence of special health care needs to produce specific child outcomes across different groups of U.S. adopted children. This study uses structural equation modeling to analyze cross-sectional data from the National Survey of Adoptive Parents to investigate differences in outcomes among three groups of U.S. adopted children: international, foster, and private. SEM results indicate that compared with privately adopted children, (a) children adopted from the foster care system were more likely to be identified with special health care needs, and (b) internationally adopted children showed on average poorer school performance as indexed by math and reading. Analyses yielded both direct and indirect paths between preadoption adversities and child outcomes, with the majority of associations mediated or partially mediated by quality of parent-child relationships and/or special health care needs status. The results of these analyses highlight the heterogeneity among different groups of adopted children within the United States and also underline the important mediating roles that the quality of parent-child relationship and children's special health care needs status have on adopted children's selected mental health and academic outcomes.

Quach, Jon; Nguyen, Cattram; O'Connor, Meredith; Wake, Melissa

We aimed to determine whether the accumulation of physical, psychosocial, and combined health adversities measured at age 8 to 9 years predicts worsening of academic scores cross-sectionally at 8 to 9 and longitudinally at 10 to 11 years. Design: Longitudinal data from Waves 3 and 4 in the Longitudinal Study of Australian Children (83% of 4983 retained). Exposures (8-9 years): Physical health adversities (yes/no; summed range, 0-5): overweight, special health care needs, chronic illness, PedsQL Physical, and global health. Psychosocial health adversities (yes/no; summed range, 0-4): parent- and teacher-reported behavior, PedsQL Psychosocial, sleep problems. Combined health adversities (range 0-9). Outcomes (8-9, and 10-11 years): National academic standardized test scores. Generalized estimating equations, accounting for multiple academic domains in each year and socioeconomic position and cognition. At 8 to 9 years, 23.9%, 9.9%, and 5.3% had 1, 2, or ≥3 physical health adversities, respectively, while 27.2%, 9.5%, and 4.9% had 1, 2, or ≥3 psychosocial health adversities. For each additional health adversity at 8 to 9 years, academic scores fell incrementally in year 3 and year 5 (both P < .001), with reductions of at least 0.4 SDs for ≥3 health adversities. Number was more important than type (physical, psychosocial) of adversity. The accumulation of health adversities predicts poorer academic achievement up to 2 years later. Interventions might need to address multiple domains to improve child academic outcomes and be delivered across the health-education interface. Copyright © 2017 Academic Pediatric Association.

Ameratunga, Rohan; Crooks, Christine; Simmons, Greg; Woon, See-Tarn

2016-01-01

Functional foods have become increasingly popular with consumers anxious to mitigate the effects of an unhealthy lifestyle or aging. In spite of attractive health claims, these products do not have legal or regulatory status in most countries and are regulated through their health claims. Regulation of functional foods by health claims does not address health risks and adverse effects of these products. In this essay regulatory aspects of functional foods are reviewed along with adverse effects published in the peer-reviewed literature. We detail why the lack of an internationally accepted definition of functional foods places consumers at risk of adverse outcomes. Our review will assist regulatory agencies, manufacturers and consumer groups to assess the benefits and reduce the risks associated with these products.

Household air pollution (HAP) from cooking with solid fuels has become a leading cause of death and disability in many developing countries including Bangladesh. We assess the association between HAP and risk of selected adverse birth and maternal health outcomes. Data for this study were extracted from Bangladesh Demographic and Health Survey conducted during 2007-2014. Selected adverse birth outcomes were acute respiratory infection (ARI) among children, stillbirth, low birth weight (LBW), under-five mortality, neonatal mortality and infant mortality. Maternal pregnancy complications and cesarean delivery were considered as the adverse maternal health outcomes. Place of cooking, use of solid fuel within the house boundary and in living room were the exposure variables. To examine the association between exposure and outcome variables, we used a series of multiple logistic regression models accounted for complex survey design. Around 90% of the respondents used solid fuel within the house boundary, 11% of them used solid fuel within the living room. Results of multiple regression indicated that cooking inside the house increased the risk of neonatal mortality (aOR,1.25; 95% CI, 1.02-1.52), infant mortality (aOR, 1.18; 95% CI, 1.00-1.40), ARI (aOR, 1.18; 95% CI, 1.08-1.33), LBW (aOR, 1.25; 95% CI, 1.10-1.43), and cesarean delivery (aOR,1.18; 95% CI, 1.01-1.29). Use of solid fuel, irrespective of cooking places, increased the risk of pregnancy complications (aOR, 1.36; 95% CI, 1.19-1.55). Compared to participants who reported cooking outside the house, the risk of ARI, LBW were significantly high among those who performed cooking within the house, irrespective of type of cooking fuel. Indoor cooking and use of solid fuel in household increase the risk of ARI, LBW, cesarean delivery, and pregnancy complication. These relationships need further investigation using more direct measures of smoke exposure and clinical measures of health outcomes. The use of clean fuels

Objective 1) Examine the relationship between previous adverse childhood experiences and somatic complaints and health problems in early adolescence, and 2) examine the role of the timing of adverse exposures. Design Prospective analysis of the Longitudinal Studies of Child Abuse and Neglect interview data when children were 4, 6, 8, 12 and 14 years old. Setting Children reported or at risk for maltreatment in the South, East, Midwest, Northwest, and Southwest United States LONGSCAN sites Participants 933 children. Main Exposures Eight categories of adversity (psychological maltreatment, physical abuse, sexual abuse, neglect, caregiver’s substance use/alcohol abuse, caregiver’s depressive symptoms, caregiver treated violently, and criminal behavior by household member) experienced during the first 6 years of life, the second six years of life, the most recent 2 years, and overall adversity Outcome Measures Child health problems including poor health, illness requiring a doctor, somatic complaints and any health problem at age 14. Results More than 90% of the youth had experienced an adverse childhood event by age 14. There was a graded relationship between adverse childhood exposures and any health problem, while 2 and ≥3 adverse exposures were associated with somatic complaints. Recent adversity uniquely predicted poor health, somatic complaints and any health problem. Conclusions Childhood adversities, particularly recent adversities, already impair the health of young adolescents. Increased efforts to prevent and mitigate these experiences may improve the health of adolescents and adults. PMID:23645114

Adverse experiences in childhood and adolescence, defined as subjectively perceived threats to the safety or security of the child's bodily integrity, family, or social structures, are known to be associated with cardiometabolic outcomes over the life course into adulthood. This American Heart Association scientific statement reviews the scientific literature on the influence of childhood adversity on cardiometabolic outcomes that constitute the greatest public health burden in the United States, including obesity, hypertension, type 2 diabetes mellitus, and cardiovascular disease. This statement also conceptually outlines pathways linking adversity to cardiometabolic health, identifies evidence gaps, and provides suggestions for future research to inform practice and policy. We note that, despite a lack of objective agreement on what subjectively qualifies as exposure to childhood adversity and a dearth of prospective studies, substantial evidence documents an association between childhood adversity and cardiometabolic outcomes across the life course. Future studies that focus on mechanisms, resiliency, and vulnerability factors would further strengthen the evidence and provide much-needed information on targets for effective interventions. Given that childhood adversities affect cardiometabolic health and multiple health domains across the life course, interventions that ameliorate these initial upstream exposures may be more appropriate than interventions remediating downstream cardiovascular disease risk factor effects later in life. © 2017 American Heart Association, Inc.

Tailoring health-related messages for young adults with adverse childhood experiences (ACEs).

The goal was to identify factors that might affect likelihood of seeking health-related interventions for young adults with adverse childhood experiences (ACEs). We tested whether ACEs were associated with (1) regulatory focus (tendency toward promoting good outcomes versus preventing bad outcomes), and (2) patient activation (the intention to take active charge of one's health). We further tested whether promotion and prevention and patient activation were associated with each other and with health. Students at a public university (N = 321) completed online questionnaires assessing ACEs, regulatory focus, patient activation, and health. Greater childhood adversity showed small but significant associations with being a less activated patient and being less focused on promoting good outcomes. In contrast, greater childhood adversity had a much stronger association with focusing on preventing negative outcomes. Students with a more significant mental health history were more likely to have been exposed to childhood adversity, to be less activated patients, and to focus more on prevention. Results suggest that using a prevention focus may be effective in health messages aimed to reach individuals with high levels of ACEs. Furthermore, individuals with high levels of ACEs may benefit from interventions aimed at increasing patient activation. Copyright © 2018 Elsevier Ltd. All rights reserved.

This study examined associations between adverse childhood family experiences and adult physical health using data from 52,250 US adults aged 18–64 from the 2009–2012 Behavioral Risk Factor Surveillance System (BRFSS). We found that experiencing childhood physical, verbal, or sexual abuse, witnessing parental domestic violence, experiencing parental divorce, and living with someone who was depressed, abused drugs or alcohol, or who had been incarcerated were associated with one or more of the following health outcomes: self-rated health, functional limitations, diabetes, and heart attack. Adult socioeconomic status and poor mental health and health behaviors significantly mediated several of these associations. The results of this study highlight the importance of family-based adverse childhood experiences on adult health outcomes and suggest that adult SES and stress-related coping behaviors may be crucial links between trauma in the childhood home and adult health.

Accelerating Adverse Outcome Pathway (AOP) development ...

EPA Pesticide Factsheets

The Adverse Outcome Pathway (AOP) framework is increasingly being adopted as a tool for organizing and summarizing the mechanistic information connecting molecular perturbations by environmental stressors with adverse outcomes relevant for ecological and human health outcomes. However, the conventional process for assembly of these AOPs is time and resource intensive, and has been a rate limiting step for AOP use and development. Therefore computational approaches to accelerate the process need to be developed. We previously developed a method for generating computationally predicted AOPs (cpAOPs) by association mining and integration of data from publicly available databases. In this work, a cpAOP network of ~21,000 associations was established between 105 phenotypes from TG-GATEs rat liver data from different time points (including microarray, pathological effects and clinical chemistry data), 994 REACTOME pathways, 688 High-throughput assays from ToxCast and 194 chemicals. A second network of 128,536 associations was generated by connecting 255 biological target genes from ToxCast to 4,980 diseases from CTD using either HT screening activity from ToxCast for 286 chemicals or CTD gene expression changes in response to 2,330 chemicals. Both networks were separately evaluated through manual extraction of disease-specific cpAOPs and comparison with expert curation of the relevant literature.

Untreated syphilis in pregnancy is associated with adverse clinical outcomes to the infant. The study aimed to estimate the public health burden resulting from adverse pregnancy outcomes due to syphilis infection among pregnant women not screened for syphilis in 43 countries in sub-Saharan Africa. Estimated country-specific incidence of syphilis was generated from annual number of live births, the proportion of women with at least 1 antenatal care (ANC) visit, the syphilis prevalence rate, and the proportion of women screened for syphilis during ANC.Adverse pregnancy outcome data (stillbirth, neonatal death, low birth weight, and congenital syphilis) were obtained from published sources. Disability-adjusted life-year (DALY) estimates were calculated using undiscounted local life expectancy, the neonatal standard loss function, and relevant disability weights. The model assessed the potential impact of raising ANC coverage to at least 95% and syphilis screening to at least 95% (World Health Organization targets). For all 43 sub-Saharan Africa countries, the estimated incidence of adverse pregnancy outcomes was 205,901 (95% confidence interval [CI], 113,256-383,051) per year, including stillbirth (88,376 [95% CI, 60,854-121,713]), neonatal death (34,959 [95% CI, 23,330-50,076]), low birth weight (22,483 [95% CI, 0-98,847]), and congenital syphilis (60,084 [95% CI, 29,073-112,414]), resulting in approximately 12.5 million DALYs. Countries with the greatest burden are (in DALYs, millions) Democratic Republic of the Congo (1.809), Nigeria (1.598), Ethiopia (1.466), and Tanzania (0.961). Attaining World Health Organization targets could reduce the burden by 8.5 million DALYs. Substantial infant mortality and morbidity results from maternal syphilis infection concentrated in countries with low access to ANC or low rates of syphilis screening.

Estimating the Potential Impact of Tobacco Control Policies on Adverse Maternal and Child Health Outcomes in the United States Using the SimSmoke Tobacco Control Policy Simulation Model.

Numerous studies document the causal relationship between prenatal smoking and adverse maternal and child health (MCH) outcomes. Studies also reveal the impact that tobacco control policies have on prenatal smoking. The purpose of this study is to estimate the effect of tobacco control policies on prenatal smoking prevalence and adverse MCH outcomes. The US SimSmoke simulation model was extended to consider adverse MCH outcomes. The model estimates prenatal smoking prevalence and, applying standard attribution methods, uses estimates of MCH prevalence and relative smoking risks to estimate smoking-attributable MCH outcomes over time. The model then estimates the effect of tobacco control policies on adverse birth outcomes averted. Different tobacco control policies have varying impacts on the number of smoking-attributable adverse MCH birth outcomes. Higher cigarette taxes and comprehensive marketing bans individually have the biggest impact with a 5% to 10% reduction across all outcomes for the period from 2015 to 2065. The policies with the lowest impact (2%-3% decrease) during this period are cessation treatment, health warnings, and complete smoke-free laws. Combinations of all policies with each tax level lead to 23% to 28% decreases across all outcomes. Our findings demonstrate the substantial impact of strong tobacco control policies for preventing adverse MCH outcomes, including long-term health implications for children exposed to low birth weight and preterm birth. These benefits are often overlooked in discussions of tobacco control. © The Author 2015. Published by Oxford University Press on behalf of the Society for Research on Nicotine and Tobacco.

Adverse outcome pathways are designed to provide a clear-cut mechanistic representation of critical toxicological effects that propagate over different layers of biological organization from the initial interaction of a chemical with a molecular target to an adverse outcome at the individual or population level. Adverse outcome pathways are currently gaining momentum, especially in view of their many potential applications as pragmatic tools in the fields of human toxicology, ecotoxicology and risk assessment. A number of guidance documents, issued by the Organization for Economic Cooperation and Development, as well as landmark papers, outlining best practices to develop, assess and use adverse outcome pathways, have been published in the last few years. The present paper provides a synopsis of the main principles related to the adverse outcome pathway framework for the toxicologist less familiar with this area, followed by two case studies relevant for human toxicology and ecotoxicology.

2004-01-01

Background and Aims: Despite recognition that occupational exposures may make a substantive contribution to the aetiology of COPD, little is known about the potential role of work related factors in COPD related health outcomes. Methods: Prospective cohort study using structured telephone interviews among a random sample of adults aged 55–75 reporting a COPD condition (emphysema, chronic bronchitis, or COPD). Using multivariate models adjusting for smoking and demographic factors, the separate and combined associations were estimated between occupational exposure to vapours, gas, dust, or fumes (VGDF) and leaving work due to lung disease (respiratory related work disability) with health outcomes and utilisation ascertained at one year follow up. Results: Of 234 subjects, 128 (55%) reported exposure to VGDF on their longest held jobs, 58 (25%) reported respiratory related work disability, and 38 (16%) subjects reported both. Combined exposure to VGDF and respiratory related work disability (rather than either factor alone) was associated with the greatest risk at follow up of frequent (everyday) restricted activity days attributed to a breathing or lung condition (OR 3.8; 95% CI 1.4 to 10.1), emergency department (ED) visit (OR 3.9; 95% CI 1.4 to 10.5), and hospitalisation (OR 7.6; 95% CI 1.8 to 32). Conclusions: Among persons with COPD, past occupational exposures and work disability attributed to lung disease, particularly in combination, appear to be risk factors for adverse health related outcomes.

EPA Pesticide Factsheets

The adverse outcome pathway (AOP) framework was developed to help organize and disseminate existing knowledge concerning the means through which specific perturbations of biological pathways can lead to adverse outcomes considered relevant to risk-based regulatory decision-making. Because many fundamental molecular and cellular pathways are conserved across taxa, data from assays that screen chemicals for their ability to interact with specific biomolecular targets can often be credibly applied to a broad range of species, even if the apical outcomes of those perturbations may differ. Information concerning the different trajectories of adversity that molecular initiating events may take in different taxa, life stages, and sexes of organisms can be captured in the form of an AOP network. As an example, AOPs documenting divergent consequences of thyroid peroxidase (TPO) and deiodinase (DIO) inhibition in mammals, amphibians, and fish have been developed. These AOPs provide the foundation for using data from common in vitro assays for TPO or DIO activity to inform both human health and ecological risk assessments. They also provide the foundation for an integrated approach to testing and assessment, where available information and biological understanding can be integrated in order to formulate plausible and testable hypotheses which can be used to target in vivo testing on the endpoints of greatest concern.

'Social capital' refers to social norms, relationships, networks and values that affect the functioning and development of society. Social capital influences health positively, but its role in the treatment outcomes of tuberculosis (TB) is not known. To study the role of social capital in determining adverse TB treatment outcomes. Of 516 patients registered under the Revised National Tuberculosis Control Programme in 2014 in Wardha Tuberculosis Unit, Wardha, India, we included 88 patients with adverse treatment outcomes as cases and 187 controls from among those without adverse outcomes. Multiple logistic regression was used to compare standardised Z-scores. A greater proportion of controls than cases belonged to higher quartiles of social capital and its domains than cases, and the mean standardised Z-score was also consistently higher among controls than cases. Respectively 47% and 15% of cases and controls were in the poorest quartile of social capital, whereas respectively 10% and 33% of cases and controls were in the richest quartile. Each unit increase in Z-score of overall social capital reduced the odds of adverse treatment outcomes by 63.1%. Appropriate interventions for building social capital for TB patients and linking them with the programme would improve programme performance.

Exposure to arsenic has a number of known detrimental health effects but impact on pregnancy outcomes is not as widely recognized. This narrative review examines existing epidemiological evidence investigating the association between arsenic exposure via drinking water and adverse pregnancy outcomes. We reviewed published epidemiological studies from around the world on impact of chronic arsenic exposure on spontaneous abortion, stillbirth, neonatal death, post neonatal death, low birth weight and preterm baby. Plausible mechanisms of arsenic toxicity causing adverse pregnancy outcomes were also determined through literature review. There is convincing evidence to support the association between high inorganic arsenic exposure (>50 ppb) and spontaneous abortion, stillbirth and low birth weight. Limitations of certain studies include study design, small sample size, recall constraints and exposure assessment. There needs to be further research investigating the dose metered impact of arsenic exposure on pregnancy outcomes. Further research on impact of low-moderate arsenic concentration exposure on pregnancy outcomes will allow for appropriate public health policy recommendations.

Objectives To investigate incidence and distribution of major adverse reproductive health problems related to various kinds of industries in Korea and to compare risks for major reproductive outcomes to assess maternal health in working and non-working women. Methods We requested claim data from the Korean National Health Insurance. We defined reference groups as (1) non-working women and (2) workers in the education field. Women working in each industry were compared with reference groups regarding rates of miscarriage, threatened abortion, preterm labor, and intrauterine growth restriction. Logistic regression was used for multivariate analysis, and age and income adjustment was performed. Results The percentages of all adverse obstetric outcomes were higher in working women than in non-working women. Working women had higher and statistically significant adjusted odds ratios (ORs) for miscarriage in 18 of the 21 industries. The age and income-adjusted OR for miscarriage for all working women was 1.26 (95% confidence interval, 1.23–1.28). Business facilities management and business support services, manufacturing, human health and social work activities, wholesale and retail trade, and professional, scientific, and technical activities were major industries with higher adjusted ORs for adverse obstetric outcomes. Conclusions We confirmed that compared to non-working women, working women have a higher risk for adverse pregnancy outcomes. Thus, adverse pregnancy outcomes such as threatened abortion, preterm labor, and intrauterine growth restriction may be associated with working status. This exploratory study identified several industries where in-depth studies are required in future to improve occupational safety in women of reproductive age. PMID:28850585

Maternal mortality is too rare in high income countries to be used as a marker of the quality of maternity care. Consequently severe maternal morbidity has been suggested as a better indicator. Using the maternal morbidity outcome indicator (MMOI) developed and validated for use in routinely collected population health data, we aimed to determine trends in severe adverse maternal outcomes during the birth admission and in particular to examine the contribution of postpartum haemorrhage (PPH). We applied the MMOI to the linked birth-hospital discharge records for all women who gave birth in New South Wales, Australia from 1999 to 2004 and determined rates of severe adverse maternal outcomes. We used frequency distributions and contingency table analyses to examine the association between adverse outcomes and maternal, pregnancy and birth characteristics, among all women and among only those with PPH. Using logistic regression, we modelled the effects of these characteristics on adverse maternal outcomes. The impact of adverse outcomes on duration of hospital admission was also examined. Of 500,603 women with linked birth and hospital records, 6242 (12.5 per 1,000) suffered an adverse outcome, including 22 who died. The rate of adverse maternal outcomes increased from 11.5 in 1999 to 13.8 per 1000 deliveries in 2004, an annual increase of 3.8% (95%CI 2.3-5.3%). This increase occurred almost entirely among women with a PPH. Changes in pregnancy and birth factors during the study period did not account for increases in adverse outcomes either overall, or among the subgroup of women with PPH. Among women with severe adverse outcomes there was a 12% decrease in hospital days over the study period, whereas women with no severe adverse outcome occupied 23% fewer hospital days in 2004 than in 1999. Severe adverse maternal outcomes associated with childbirth have increased in Australia and the increase was entirely among women who experienced a PPH. Reducing or stabilising

Gastroschisis: antenatal sonographic predictors of adverse neonatal outcome.

Page, Rachael; Ferraro, Zachary Michael; Moretti, Felipe; Fung, Karen Fung Kee

2014-01-01

The aim of this review was to identify clinically significant ultrasound predictors of adverse neonatal outcome in fetal gastroschisis. A quasi-systematic review was conducted in PubMed and Ovid using the key terms "gastroschisis," "predictors," "outcome," and "ultrasound." A total of 18 papers were included. The most common sonographic predictors were intra-abdominal bowel dilatation (IABD), intrauterine growth restriction (IUGR), and bowel dilatation not otherwise specified (NOS). Three ultrasound markers were consistently found to be statistically insignificant with respect to predicting adverse outcome including abdominal circumference, stomach herniation and dilatation, and extra-abdominal bowel dilatation (EABD). Gastroschisis is associated with several comorbidities, yet there is much discrepancy in the literature regarding which specific ultrasound markers best predict adverse neonatal outcomes. Future research should include prospective trials with larger sample sizes and use well-defined and consistent definitions of the adverse outcomes investigated with consideration given to IABD.

The advent of adverse outcome pathways (AOPs) has provided a new lexicon for description of mechanistic toxicology, and a renewed enthusiasm for exploring modes of action resulting in adverse health and environmental effects. In addition, AOPs have been used successfully as a framework for the design and development of non-animal approaches to toxicity testing. Although the value of AOPs is widely recognised, there remain challenges and opportunities associated with their use in practise. The purpose of this article is to consider specifically how the future trajectory of AOPs may provide a basis for addressing some of those challenges and opportunities.

To examine whether childhood adversity is associated with depressive symptoms, suicide attempts, or psychiatric hospitalization. History of seven childhood adversities (physical neglect, verbal abuse, physical abuse, sexual abuse, parental death, parental incarceration, and child welfare system placement) was gathered through in-person interviews. Multivariate models examined associations between history of childhood adversities and moderate to severe depressive symptoms, lifetime history of suicide attempt, or lifetime history of psychiatric hospitalization. The study enrolled 350 homeless adults, aged 50 and older, in Oakland, California, using population-based sampling methods. Moderate to severe depressive symptoms were measured on a Center for Epidemiologic Studies-Depression Scale (≥22), self-reported lifetime history of suicide attempt, and self-reported lifetime history of psychiatric hospitalization. Participants with exposure to one childhood adversity had elevated odds of reporting moderate to severe depressive symptoms (adjusted odds ratio [AOR]: 2.0; 95% confidence interval [CI]: 1.1-3.7) and lifetime history of suicide attempt (AOR: 4.6; 95% CI: 1.0-21.6) when compared with those who had none; the odds of these two outcomes increased with exposure to additional childhood adversities. Participants with four or more childhood adversities had higher odds of having a lifetime history of psychiatric hospitalization (AOR: 7.1; 95% CI: 2.8-18.0); no increase with fewer adversities was found. Childhood adversities are associated with poor mental health outcomes among older homeless adults. Clinicians should collect information about childhood adversities among this high-risk population to inform risk assessment and treatment recommendations.

Objectives To examine the association between adverse childhood experiences (ACEs) and pregnancy outcomes; to explore mediators of this association including psychiatric illness and health habits. Methods Exposure to ACEs was determined by the Early Trauma Inventory Self Report Short Form; psychiatric diagnoses were generated by the Composite International Diagnostic Interview administered in a cohort of 2303 pregnant women. Linear regression and structural equation modeling bootstrapping approaches tested for multiple mediators. Results Each additional ACE decreased birth weight by 16.33 g and decreased gestational age by 0.063. Smoking was the strongest mediator of the effect on gestational age. Conclusions ACEs have an enduring effect on maternal reproductive health, as manifested by mothers’ delivery of offspring that were of reduced birth weight and shorter gestational age. PMID:26762511

Bacterial invasion in subgingival sites especially of gram-negative organisms are initiators for periodontal diseases. The periodontal pathogens with persistent inflammation lead to destruction of periodontium. In recent years, periodontal diseases have been associated with a number of systemic diseases such as rheumatoid arthritis, cardiovascular-disease, diabetes mellitus, chronic respiratory diseases and adverse pregnancy outcomes including pre-term low-birth weight (PLBW) and pre-eclampsia. The factors like low socio-economic status, mother's age, race, multiple births, tobacco and drug-abuse may be found to increase risk of adverse pregnancy outcome. However, the same are less correlated with PLBW cases. Even the invasion of both aerobic and anerobic may lead to inflammation of gastrointestinal tract and vagina hence contributing to PLBW. The biological mechanism involved between PLBW and Maternal periodontitis is the translocation of chemical mediators of inflammation. Pre-eclampsia is one of the commonest cause of both maternal and fetal morbidity as it is characterized by hypertension and hyperprotenuria. Improving periodontal health before or during pregnancy may prevent or reduce the occurrences of these adverse pregnancy outcomes and, therefore, reduce the maternal and perinatal morbidity and mortality. Hence, this article is an attempt to review the relationship between periodontal condition and altered pregnancy outcome.

Maternal obesity is a global epidemic affecting the developed and developing world. Human and animal studies indicate that maternal obesity programs development predisposing offspring to later-life chronic diseases. Several mechanisms act together to produce these adverse health problems. There is a need for effective interventions that prevent these outcomes and guide management in human pregnancy. We report here dietary and exercise intervention studies in both altricial and precocial species, rats and sheep, designed to prevent adverse offspring outcomes. Both interventions present exciting opportunities to at least in part prevent adverse metabolic and other outcomes in mother and offspring. PMID:24147928

We studied 1991 Gulf War (GW)-related environmental exposures and adverse birth outcomes in Iraqis. A random cross-sectional sample of 307 Iraqi families that immigrated to the United States responded to a structured interview covering socioeconomics, lifestyle, environmental exposures, and birth outcome. Data per each family was collected either from the man or the woman in the respective family. The respondents were divided into those that resided in Iraq during and following the GW (post-GW, n=185) and those that had left before (pre-GW, n=122). The primary outcome was lifetime prevalence of adverse birth outcomes, ie, congenital anomalies, stillbirth, low birth weight, and preterm delivery and its relationship to GW exposures. Mean number of adverse birth outcomes increased from 3.43 (SD=2.11) in the pre-GW to 4.63 (SD=2.63) in the post-GW group (P<.001). Mean chemical (Ch) and nonchemical (NCh) environmental exposure scores increased from pre-GW scores of 0.38 units (SD=1.76) and 0.43 (SD=1.86), respectively, to post-GW scores of 5.65 units (SD=6.23) and 7.26 (SD=5.67), P<.001 between groups for both exposures. There was a significant dose-response relationship between Ch environmental exposure (P=.001), but not NCh exposure, and number of adverse birth outcomes. Exposure to burning oil pits and mustard gas increased the risks for specific adverse birth outcomes by 2 to 4 times. Results indicate that Gulf War Ch, but not NCh exposures are related to adverse birth outcomes. Pregnancies in women with a history of war exposures might benefit from more intensive observation.

Research on the potential impact of air pollution on the human's health has increased rapidly in recent years. Several studies have suggested that exposure to air pollutants during period of pregnancy which is a crucial time point of mother-fetus development may have long-term and serious impact on adverse pregnancy outcomes. There is lack of review to evaluate the existed epidemiologic evidence on the associations between air pollutants and adverse pregnancy outcomes in China, so we conducted a review to explore the current epidemiological evidence on the effects of air pollutants to pregnancy outcomes and possible mechanisms during the pregnancy process. We used keywords to systematically search all the English and Chinese literatures on studies that were conducted in China. Exposure to air pollutants during pregnancy had shown there were harmful effects for different birth outcomes: preterm birth, low birth weight, stillbirth, birth defects, infertility, and macrosomia fetus. Results on the effects of air pollutants on adverse pregnancy outcomes are small and inconsistent because they vary in their design and methodology. The existed available evidence is compatible with either a small negative effect of air pollutants on pregnancy outcomes or with no effect; therefore, further studies are needed to confirm and quantify the possible associations and potential biologic mechanisms between air pollutants and pregnancy outcomes.

Childhood and adolescent adversity have been shown to predict later mental and physical health outcomes. Understanding which aspects and developmental timings of adversity are important, and the mechanisms by which they have their impact may help guide intervention approaches. A large subset of adolescents (N = 457; Female 68.9%) from the 10-year longitudinal Youth Emotion Project was examined to better understand the associations among childhood/adolescent adversity, substance use disorder, and later health quality. Adolescent (but not childhood) adversities were associated with poorer health in late adolescence/early adulthood, adolescent adversities were associated with subsequent onset of substance use disorder, and adolescent adversities continued to be associated with poorer health in late adolescence/early adulthood after accounting for the variance explained by substance use disorder onset. These associations were observed after statistically accounting for emotional disorders and socioeconomic status. Specific domains of adversity uniquely predicted substance use disorder and poorer health outcomes. In contrast with current recent research, our findings suggest the association between childhood/adolescent adversity and poorer health outcomes in late adolescence and emerging adulthood are not entirely accounted for by substance use disorder, suggesting efforts to curtail family-based adolescent adversity may have downstream health benefits.

Childhood Adversity, Religion, and Change in Adult Mental Health.

2018-02-01

Research indicates that childhood adversity is associated with poor mental health in adulthood. The purpose of this study is to examine whether the deleterious long-term effects of childhood adversity on adult mental health are reduced for individuals who are involved in religious practices. Using longitudinal data from a representative sample of American adults ( N = 1,635), I find that religious salience and spirituality buffer the noxious effects of childhood abuse on change in positive affect over time. By contrast, these stress-buffering properties of religion fail to emerge when negative affect serves as the outcome measure. These results underscore the importance of religion as a countervailing mechanism that blunts the negative impact of childhood abuse on adult mental health over time. I discuss the theoretical implications of these findings for views about religion, childhood adversity, and mental health.

To determine whether greater dispositional mindfulness is associated with better adult health across a range of exposures to adverse childhood experiences (ACEs). In 2012, a web-based survey of 2160 Pennsylvania Head Start staff was conducted. We assessed ACE score (count of eight categories of childhood adversity), dispositional mindfulness (Cognitive and Affective Mindfulness Scale-Revised), and the prevalence of three outcomes: multiple health conditions (≥ 3 of 7 conditions), poor health behavior (≥ 2 of 5 behaviors), and poor health-related quality of life (HRQOL) (≥ 2 of 5 indicators). Respondents were 97% females, and 23% reported ≥ 3 ACEs. The prevalences of multiple health conditions, poor health behavior, and poor HRQOL were 29%, 21%, and 13%, respectively. At each level of ACE exposure, health outcomes were better in those with greater mindfulness. For example, among persons reporting ≥ 3 ACEs, those in the highest quartile of mindfulness had a prevalence of multiple health conditions two-thirds that of those in the lowest quartile (adjusted prevalence ratio (95% confidence interval)=0.66 (0.51, 0.86)); for those reporting no ACEs, the ratio was 0.62 (0.41, 0.94). Across a range of exposures to ACEs, greater dispositional mindfulness was associated with fewer health conditions, better health behavior, and better HRQOL. Copyright © 2014 Elsevier Inc.

abnormal laboratory test results accumulate with age and can be common in people with few clinically detectable health deficits. A frailty index (FI) based entirely on common physiological and laboratory tests (FI-Lab) might offer pragmatic and scientific advantages compared with a clinical FI (FI-Clin). to compare the FI-Lab with the FI-Clin and to assess their individual and combined relationships with mortality and other adverse health outcomes. secondary analysis of the eight-centre, longitudinal European Male Ageing Study (EMAS) of community-dwelling men aged 40-79 at baseline. Follow-up assessment occurred 4.4 ± 0.3 (mean ± SD) years later. we constructed a 23-item FI using common laboratory tests, blood pressure and pulse (FI-Lab), compared it with a previously validated 39-item FI using self-report and performance-based measures (FI-Clin) and finally combined both FIs to create a 62-item FI-Combined. Outcomes were all-cause mortality, institutionalisation, doctor visits, medication use, self-reported health, falls and fractures. the mean FI-Lab score was 0.28 ± 0.11, the FI-Clin was 0.13 ± 0.11 and FI-Combined was 0.19 ± 0.09. Age-adjusted models demonstrated that each FI was associated with mortality [HR (CI) FI-Lab: 1.04 (1.03-1.06); FI-Clin: 1.05 (1.04-1.06); FI-Combined: 1.07 (1.06-1.09)], institutionalisation, doctor visits, medication use, self-reported health and falls. Combined in a model with FI-Clin, the FI-Lab remained independently associated with mortality, institutionalisation, doctor visits, medication use and self-reported health. the FI-Lab detected an increased risk of adverse health outcomes alone and in combination with a clinical FI; further evaluation of the feasibility of the FI-Lab as a frailty screening tool within hospital care settings is needed. © The Author 2016.

Developing and applying the adverse outcome pathway ...

EPA Pesticide Factsheets

To support a paradigm shift in regulatory toxicology testing and risk assessment, the Adverse Outcome Pathway (AOP) concept has recently been proposed. This concept is similar to that for Mode of Action (MOA), describing a sequence of measurable key events triggered by a molecular initiating event in which a stressor interacts with a biological target. The resulting cascade of key events includes molecular, cellular, structural and functional changes in biological systems, resulting in a measurable adverse outcome. Thereby, an AOP ideally provides information relevant to chemical structure-activity relationships as a basis to predict effects for structurally similar compounds. AOPs could potentially also form the basis for qualitative and quantitative predictive modeling of the human adverse outcome resulting from molecular initiating or other key events for which higher-throughput testing methods are available or can be developed.A variety of cellular and molecular processes are known to be critical to normal function of the central (CNS) and peripheral nervous systems (PNS). Because of the biological and functional complexity of the CNS and PNS, it has been challenging to establish causative links and quantitative relationships between key events that comprise the pathways leading from chemical exposure to an adverse outcome in the nervous system. Following introduction of principles of the description and assessment of MOA and AOPs, examples of adverse out

Urinary tract infections (UTIs) during pregnancy are among the commonest health problems world wide, specially in developing countries, including Egypt. It has several adverse outcomes not only on the mother but also on the fetus as well.. The aim of this study is to determine the incidence of UTIs during pregnancy, study the main risk factors associated with such infections and find the impact of these infections on some pregnancy outcomes namely the gestational age and birth weight. A follow-up study on 249 pregnant women attending the ante natal care clinic at Zagazig university hospital. They were recruited over a period from 1st of September to 30th of or November, 2005. The outcome could be recorded for 201 of them. Data were collected through a pretested questionnaire, repeated urine analyses and recording of outcome of pregnancy. The study revealed that the incidence of UTIs during pregnancy was 31.3%. The commonest organisms were Klebsiella and E-coli. Several socio-demographic characteristics were found significantly associated with UTIs, age being 30 years and more, illiterates and low educational level, low socio-economic level and those with unsatisfactory personal hygiene and those using underwear clothes other than cotton. Significant associations with UTIs were also found in multigravidae 4th and more, those having more than one child and those who previously suffered UTIs. The only predicting variable with UTIs was low socio-economic level. The study revealed that the probability of delivering premature infants and low birth weights was significantly higher among those who experienced UTIs during pregnancy. Multivariate analysis revealed that UTI was one of the main contributors to pre-mature deliveries. Urinary tract infections with pregnancy still constitute a big problem with high incidence. It has a great impact on pregnancy outcome mainly pre-mature labor. So, the study recommends health education about personal hygiene, repeated urine

We tested whether declining motor function accelerates with age in older African-Americans. Eleven motor performances were assessed annually in 513 older African-Americans. During follow-up of 5 years, linear mixed-effect models showed that motor function declined by about 0.03 units/year (Estimate, -0.026, p<0.001); about 4% more rapidly for each additional year of age at baseline. A proportional hazard model showed that both baseline motor function level and its rate of change were independent predictors of death and incident disability (all p's<0.001). These models showed that the additional annual amount of motor decline in 85 year old persons at baseline versus 65 year old persons was associated with a 1.5-fold higher rate of death and a 3-fold higher rate of developing Katz disability. The rate of declining motor function accelerates with increasing age and its rate of decline predicts adverse health outcomes in older African-Americans. Copyright © 2015 Elsevier Inc.

To assess the mechanisms accounting for the transfer of risk from one generation to the next, especially as they relate to maternal adverse childhood experiences and infant physical and emotional health outcomes. Participants were 501 community mother-infant dyads recruited shortly after the birth and followed up at 18 months. Mothers retrospectively reported on their adverse childhood experiences. The main outcome measures were parent-reported infant physical health and emotional problems. Potential mechanisms of intergenerational transmission included cumulative biomedical risk (eg, prenatal and perinatal complications) and postnatal psychosocial risk (eg, maternal depression, single parenthood, marital conflict). Four or more adverse childhood experiences were related to a 2- and 5-fold increased risk of experiencing any biomedical or psychosocial risk, respectively. There was a linear association between number of adverse childhood experiences and extent of biomedical and psychosocial risk. Path analysis revealed that the association between maternal adverse childhood experiences and infant physical health operated specifically through cumulative biomedical risk, while the relationship between adverse childhood experiences and infant emotional health operated specifically through cumulative psychosocial risk. This pattern was not explained by maternal childhood disadvantage or current neighborhood poverty. Maternal adverse childhood experiences confer vulnerability to prenatal, perinatal, and postnatal psychosocial health. The association between adverse childhood experiences and offspring physical and emotional health operates through discrete intermediary mechanisms. Copyright © 2017 Elsevier Inc.

2017-03-01

This study aimed at verifying the role of polypharmacy as an independent risk factor for adverse health outcomes in older emergency department (ED) patients. This was a large (n = 2057) sample of older ED patients (≥65 years) participating in an observational cohort study. Polypharmacy and excessive polypharmacy were defined as having 6-9 drug prescriptions and 10 or more drug prescriptions in the last 3 months, respectively. The total number of medication prescriptions was also available. Outcome measures were in-hospital mortality; 30-day ED return; ED revisit, hospital admission, and mortality at 6 months. Logistic and Cox regression models as well as receiver operating characteristic curves using the Youden index and the area under the curve were calculated. Polypharmacy and excessive polypharmacy were present in 624 (30.3 %) and 367 (17.8 %) subjects, respectively. The mean number of prescriptions in the last 3 months was 5.7 (range 0-25) drugs. Polypharmacy and, particularly, excessive polypharmacy were constantly and independently associated with worse outcomes. A cut-off of 6 had the highest value of the Youden Index in predicting the majority of the adverse outcomes considered. Polypharmacy and excessive polypharmacy are independent risk factors for adverse health outcomes after an ED visit. Further studies are needed to clarify whether drug related issues (such as non-compliance, inappropriate or suboptimal prescribing, adverse drug reactions, and drug-drug or drug-disease interactions) or underlying multimorbidity and disease severity, as well as clinical complexity and frailty, are responsible for the negative outcomes associated with polypharmacy.

Gynecologists’ knowledge and attitudes regarding oral health and periodontal disease leading to adverse pregnancy outcomes

Hashim, Raghad; Akbar, Madiha

2014-01-01

Objectives: A cross-sectional study was conducted to evaluate the knowledge and practiced behaviors of gynecologists regarding oral health care during pregnancy and the association of periodontal disease with adverse pregnancy outcomes. Materials and Methods: A questionnaire consisting of 16 questions was designed and pilot tested. One hundred and fifty gynecologists practicing in the private sector of United Arab Emirates (UAE) were approached to voluntarily participate and fill up the questionnaire during February–March 2014. Data retrieved were entered into Excel database and analyzed using SPSS. Results: Of the 150 gynecologists approached, 108 filled the questionnaire, yielding a response rate of 72%. The majority (95.4%) acknowledged a connection between oral health and pregnancy and 75.9% agreed that periodontal disease can affect the outcome of pregnancy. Moreover, most of the gynecologists (85.2%) advised their pregnant patients to visit the dentist during pregnancy. Almost three-quarter of the participants (73%) regarded dental radiographs to be unsafe during pregnancy and more than half (59.3%) considered administration of local anesthesia to be unsafe during pregnancy. Conclusion: The present study demonstrated that gynecologists have a relatively high degree of knowledge with respect to the relationship of periodontal disease to pregnancy outcome. However, there clearly exist misconceptions regarding the provision of dental treatment during pregnancy. To provide better oral health care, more knowledge needs to be made available to the pregnant women and the medical community, and misconceptions regarding the types of dental treatments during pregnancy should be clarified.

Poor mental health among low-income women in the U.S.: The roles of adverse childhood and adult experiences.

PubMed

Mersky, Joshua P; Janczewski, Colleen E; Nitkowski, Jenna C

2018-06-01

It is well established that exposure to a greater number of adverse childhood experiences (ACEs) increases the risk of poor physical and mental health outcomes. Given the predictive validity of ACE scores and other cumulative risk metrics, a similar measurement approach may advance the study of risk in adulthood. We examined the prevalence and interrelations of 10 adverse adult experiences, including household events such as intimate partner violence and extrafamilial events such as crime victimization. We also tested the relation between cumulative adult adversity and later mental health problems, and we examined whether adult adversity mediates the link between childhood adversity and mental health. Data were collected from 501 women in the Families and Children Thriving Study, a longitudinal investigation of low-income families that received home visiting services in Wisconsin. We conducted correlation analyses to assess interrelations among study measures along with multivariate analyses to test the effects of childhood and adult adversity on three outcomes: depression, anxiety, and posttraumatic stress disorder (PTSD). We then fit a structural equation model to test whether the effects of childhood adversity on mental health are mediated by adult adversity. Over 80% of participants endorsed at least one adverse adult experience. Adult adversities correlated with each other and with the mental health outcomes. Controlling for ACEs and model covariates, adult adversity scores were positively associated with depression, anxiety, and PTSD scores. Path analyses revealed that the ACE-mental health connection was mediated by adult adversity. Our findings indicate that mental health problems may be better understood by accounting for processes through which early adversity leads to later adversity. Pending replication, this line of research has the potential to improve the identification of populations that are at risk of poor health outcomes. Copyright © 2018

To determine whether there was an association between intra-hospital transfers and adverse outcomes. Transfers between clinical units and between beds on the same unit are routine aspects of an episode of care in acute hospitals. The rate of these transfers per episode has increased in response to high occupancy levels, a decline in bed numbers, and increased demand for hospital services. The impact of the number of transfers between both wards and beds on patient outcomes is not widely explored. Retrospective cross sectional design using hospital administrative data. Data were extracted from existing hospital administrative datasets for one large metropolitan hospital for the financial year 2008-09 in Australia (n = 14,133). Descriptive analyses and logistic regression models were developed for each of 3 selected patient outcomes. Nearly one-tenth of patients (9.2%) experienced a fall with injury, 3.8% of surgical patients a wound infection and 0.1% a complication from medication errors. For each bed or ward transfer, the odds of falls and wound infections increased. Medication errors were not associated with either bed or ward moves. Hospitals should minimise the number of bed and ward transfers per episode of care in order to reduce the likelihood of adverse patient outcomes. Current bed management policies and practices should be evaluated and further refined to address this need. Additional strategies include improving coordination and communication during and after transfer. Nurses must consider the potential cost of intrahospital transfers on patients, length of stay and bed availability. © 2017 John Wiley & Sons Ltd.

To assess incidence and risk factors of intimate partner violence (IPV) during pregnancy among a sample of women from Egypt and to evaluate its impact on maternal and fetal adverse health outcomes. After obtaining ethical approval, a total of 1,857 women aged 18 - 43 years completed the study and were investigated using an interview questionnaire. The questionnaire contains five main items: demographic characteristics of women, intimate partner characteristics, assessment of IPV during current pregnancy, and assessment of maternal as well as fetal/neonatal adverse outcomes. Women were also examined to detect signs of violence and identify injuries. Exposure to IPV during pregnancy was reported among 44.1% of the studied women. Emotional violence was the most common form. Women exposed to violence were of younger age, higher parity, and lower educational level. Their partners were older, less educated, and more likely to be addicted to drugs and alcohol. Women were also found to have significantly higher incidence of adverse pregnancy outcomes (miscarriage, preterm labor, and premature rupture of membrane), and fetal/neonatal adverse outcomes (fetal distress, fetal death, and low birth weight). A total of 297 cases had been exposed to physical violence (15.9%) vs 32.6% and 10% exposed to emotional and sexual violence, respectively. The most common form of physical violence was kicking. Violence during pregnancy is prevalent among Egyptian women. Exposure to violence was a significant risk factor for multiple adverse maternal and fetal health outcomes.

Psychoneuroimmunology in Pregnancy: Immune Pathways Linking Stress with Maternal Health, Adverse Birth Outcomes, and Fetal Development

PubMed Central

Christian, Lisa M.

2011-01-01

It is well-established that psychological stress promotes immune dysregulation in nonpregnant humans and animals. Stress promotes inflammation, impairs antibody responses to vaccination, slows wound healing, and suppresses cell-mediated immune function. Importantly, the immune system changes substantially to support healthy pregnancy, with attenuation of inflammatory responses and impairment of cell-mediated immunity. This adaptation is postulated to protect the fetus from rejection by the maternal immune system. Thus, stress-induced immune dysregulation during pregnancy has unique implications for both maternal and fetal health, particularly preterm birth. However, very limited research has examined stress-immune relationships in pregnancy. The application of psychoneuroimmunology research models to the perinatal period holds great promise for elucidating biological pathways by which stress may affect adverse pregnancy outcomes, maternal health, and fetal development.

Limited English proficiency is associated with disparities across diverse health outcomes. However, evidence regarding adverse birth outcomes across languages is limited, particularly among U.S. Asian and Pacific Islander populations. The study goal was to consider the relationship of maternal language to birth outcomes using statewide hospitalization data. Detailed discharge data from Hawaii childbirth hospitalizations from 2012 (n = 11,419) were compared by maternal language (English language or not) for adverse outcomes using descriptive and multivariable log-binomial regression models, controlling for race/ethnicity, age group, and payer. Ten percent of mothers spoke a language other than English; 93% of these spoke an Asian or Pacific Islander language. In multivariable models, compared to English speakers, non-English speakers had significantly higher risk (adjusted relative risk [ARR]: 2.02; 95% confidence interval [CI]: 1.34-3.04) of obstetric trauma in vaginal deliveries without instrumentation. Some significant variation was seen by language for other birth outcomes, including an increased rate of primary Caesarean sections and vaginal births after Caesarean, among non-English speakers. Non-English speakers had approximately two times higher risk of having an obstetric trauma during a vaginal birth when other factors, including race/ethnicity, were controlled. Non-English speakers also had higher rates of potentially high-risk deliveries.

Considering the highest rate of morbidity and mortality in diamniotic monochorionic twins, the authors evaluated and compared the adverse obstetric and perinatal outcome in twin pregnancies according to chorionicity. A retrospective study was conducted in all twin deliveries that occurred in the Obstetric Unit of Maternidade Bissaya-Barreto, for a period of tree years (from the 1st of January 1999 until the 31st of December 2001). From de 140 diamniotic twin pregnancies studied, we considered two groups according to the chorionicity: monochorionic and dichorionic. We compared multiple parameters as, epidemiologic data, adverse obstetric outcome, gestacional delivery age, type of delivery and the morbidity, the mortality and the follow-up of the newborn. The statistic tests used were the X2 and the t student. From the 140 twin pregnancies included in the study, 66% (92 cases) presented dichorionic placentation and 34% (48 cases) were monochorionic. In the group of monochorionic pregnancies, we observed highly difference related to pathology of amniotic fluid (14.5% vs 2.2%), discordant fetal growth (41.6% vs 22.8%) and rate of preterm delivery (66.6% vs 32.6%). Related to the newborn we verified that they had a lower average birth weight (1988g vs 2295g), a highly rate of weight discordancy (23% vs 15.3%), intraventricular haemorrhage (2.2% vs 0%) and IUGR (6.6% vs 1.6%), statistically significant in the monochorionic group. Also the perinatal mortality rate was significantly higher in the monochorionic pregnancies (93.7 per thousand vs 21.7 per thousand). The high rate of morbidity and mortality related to the monochorionic twin pregnancies, implies the need of a correct identification of the type of chorionicity and also a high standard of prenatal surveillance in prenatal specialised health centers.

Chronic arsenic exposure is a public health concern in many parts of the world, with elevated concentrations in groundwater posing a threat to millions of people. Arsenic is associated with various cancers and an array of chronic diseases; however, the relationship with adverse pregnancy outcomes and child mortality is less established. We evaluated associations between individual-level prenatal arsenic exposure with adverse pregnancy outcomes and child mortality in a pregnancy study among 498 women nested in a larger population-based cohort in rural Bangladesh. Creatinine-adjusted urinary total arsenic concentration, a comprehensive measure of exposure from water, food, and air sources, reflective of the prenatal period was available for participants. Self-reported pregnancy outcomes (livebirth, stillbirth, spontaneous/elective abortion) were ascertained. Generalized estimating equations, accounting for multiple pregnancies of participants, were used to estimate odds ratios and 95% confidence intervals in relation to adverse pregnancy outcomes. Vital status of livebirths was subsequently ascertained through November 2015. Cox proportional hazards models were used to estimate hazard ratios and 95% confidence intervals in relation to child mortality. We observed a significant association between prenatal arsenic exposure and the risk of stillbirth (greater than median; adjusted OR = 2.50; 95% CI = 1.04, 6.01). We also observed elevated risk of child mortality (greater than median; adjusted HR = 1.92; 95% CI = 0.78, 4.68) in relation to prenatal arsenic exposure. Prospective studies should continue to evaluate prenatal and early life health effects of arsenic exposure and arsenic remediation strategies for women of child-bearing age.

Agricultural pesticide use and adverse birth outcomes in the San Joaquin Valley of California.

Larsen, Ashley E; Gaines, Steven D; Deschênes, Olivier

2017-08-29

Virtually all agricultural communities worldwide are exposed to agricultural pesticides. Yet, the health consequences of such exposure are poorly understood, and the scientific literature remains ambiguous. Using individual birth and demographic characteristics for over 500 000 birth observations between 1997-2011 in the agriculturally dominated San Joaquin Valley, California, we statistically investigate if residential agricultural pesticide exposure during gestation, by trimester, and by toxicity influences birth weight, gestational length, or birth abnormalities. Overall, our analysis indicates that agricultural pesticide exposure increases adverse birth outcomes by 5-9%, but only among the population exposed to very high quantities of pesticides (e.g., top 5th percentile, i.e., ~4200 kg applied over gestation). Thus, policies and interventions targeting the extreme right tail of the pesticide distribution near human habitation could largely eliminate the adverse birth outcomes associated with agricultural pesticide exposure documented in this study.The health consequences of exposure to pesticides are uncertain and subject to much debate. Here, the effect of exposure during pregnancy is investigated in an agriculturally dominated residential area, showing that an increase in adverse birth outcomes is observed with very high levels of pesticide exposure.

Further evidence for periodontal disease as a risk indicator for adverse pregnancy outcomes.

Although there is increasing evidence to suggest an association between periodontal disease and adverse pregnancy outcomes, the issue remains controversial. This study tested the hypothesis that periodontal disease is a risk indicator for preterm delivery of low-birthweight infants. The study sample comprised 443 pregnant women with a mean (± standard deviation) age of 24.13 (±5.30) years. At first visit, maternal oral health status was assessed by the measurement of probing pocket depth and clinical attachment loss, and periodontal status was graded as absent, mild, moderate or severe. An association was sought between pregnancy outcomes and maternal periodontal status. While controlling for other factors, significant associations were found between pregnancy outcomes and maternal periodontal index scores. This study provides further evidence that periodontal disease is a risk indicator for adverse pregnancy outcomes. © 2016 FDI World Dental Federation.

This study aimed to measure the relative contribution of adverse experiences to adolescent behavioral health problems using administrative data. Specifically, we sought to understand the predictive value of adverse experiences on the presence of mental health and substance abuse problems for youth receiving publicly funded social and health services. Medicaid claims and other service records were analyzed for 125,123 youth age 12-17 and their biological parents. Measures from administrative records reflected presence of parental domestic violence, mental illness, substance abuse, criminal justice involvement, child abuse and/or neglect, homelessness, and death of a biological parent. Mental health and substance abuse status of adolescents were analyzed as functions of adverse experiences and other youth characteristics using logistic regression. In multivariate analyses, all predictors except parental domestic violence were statistically significant for substance abuse; parental death, parental mental illness, child abuse or neglect and homelessness were statistically significant for mental illness. Odds ratios for child abuse/neglect were particularly high in both models. The ability to identify risks during childhood using administrative data suggests the potential to target prevention and early intervention efforts for children with specific family risk factors who are at increased risk for developing behavioral health problems during adolescence. This study illustrates the utility of administrative data in understanding adverse experiences on children and the advantages and disadvantages of this approach. Copyright © 2015 Elsevier Ltd.

2014-03-01

To examine whether and when effects of cumulative adversity in the first 7 years of life are evident in relation to 3 childhood markers of risk for poor adult physical health. The study data are from an English birth cohort. Parental reports of 8 social risk factors were obtained during the child's first 7 years, and scores were created to reflect cumulative adversity at 4 developmental periods. At age 7 and 11 years, weight, height, and blood pressure (BP) were measured by clinic staff, and caregivers reported behavior problems. Linear regression was used to estimate associations of cumulative adversity with each outcome (n = 4361) and changes in these outcomes between 7 and 11 years (n = 3348). At age 7 years, mean adversity and chronic exposure to high adversity were associated with elevated body mass index (BMI) and internalizing and externalizing symptoms (P < .05), but not elevated BP. Adversity in all developmental periods was associated with elevated numbers of internalizing and externalizing symptoms (P < .0001), but associations were less robust for BMI. Adversity did not predict change in BMI or BP between age 7 and 11 years, however, it predicted increases in internalizing and externalizing symptoms (P < .0001). Cumulative adversity was associated with BMI and behavior problems at age 7 years, and our data indicate that timing and chronicity of exposure to adversity differentially influence diverse indicators of long-term health risk commonly measured in childhood. This research suggests the hypothesis that interventions to address adversity could reduce the development of multiple chronic disease risk factors and limit their effects on health.

Nigg, Joel

2015-01-01

Attention-deficit/hyperactivity disorder (ADHD) is defined by extreme levels of inattention–disorganization and/or hyperactivity–impulsivity. In DSM-IV, the diagnostic criteria required impairment in social, academic, or occupational functioning. With DSM-5 publication imminent in 2013, further evaluation of impairment in ADHD is timely. This article reviews the current state of knowledge on health-related impairments of ADHD, including smoking, drug abuse, accidental injury, sleep, obesity, hypertension, diabetes, and suicidal behavior. It concludes by suggesting the need for new avenues of research on mechanisms of association and the potential for ADHD to be an early warning sign for secondary prevention of some poor health outcomes.

Sleep loss, circadian desynchronization, and work overload occur to some extent for ground and flight crews, prior to and during spaceflight missions. Ground evidence indicates that such risk factors may lead to performance decrements and adverse health outcomes, which could potentially compromise mission objectives. Efforts are needed to identify the environmental and mission conditions that interfere with sleep and circadian alignment, as well as individual differences in vulnerability and resiliency to sleep loss and circadian desynchronization. Specifically, this report highlights a collection of new evidence to better characterize the risk and reveals new gaps in this risk.

2018-07-01

Adverse birth outcomes such as preterm birth and low birth weight are significant public health concerns and contribute to neonatal morbidity and mortality. Studies have increasingly been exploring the predictive effects of maternal posttraumatic stress disorder (PTSD) on adverse birth outcomes. However, the biological mechanisms by which maternal PTSD affects birth outcomes are not well understood. Allostatic load refers to the cumulative dysregulations of the multiple physiological systems as a response to multiple social-ecological levels of chronic stress. Allostatic load has been well documented in relation to both chronic stress and adverse health outcomes in non-pregnant populations. However, the mediating role of allostatic load is less understood when it comes to maternal PTSD and adverse birth outcomes. To propose a theoretical model that depicts how allostatic load could mediate the impact of maternal PTSD on birth outcomes. We followed the procedures for theory synthesis approach described by Walker and Avant (2011), including specifying focal concepts, identifying related factors and relationships, and constructing an integrated representation. We first present a theoretical overview of the allostatic load theory and the other 4 relevant theoretical models. Then we provide a brief narrative review of literature that empirically supports the propositions of the integrated model. Finally, we describe our theoretical model. The theoretical model synthesized has the potential to advance perinatal research by delineating multiple biomarkers to be used in future. After it is well validated, it could be utilized as the theoretical basis for health care professionals to identify high-risk women by evaluating their experiences of psychosocial and traumatic stress and to develop and evaluate service delivery and clinical interventions that might modify maternal perceptions or experiences of stress and eliminate their impacts on adverse birth outcomes.

Exposure to childhood adversity has an impact on adult mental health, increasing the risk for depression and suicide. Associations between Adverse Childhood Experiences (ACEs) and several adult mental and behavioral health outcomes are well documented in the literature, establishing the need for prevention. The current study analyzes the relationship between an expanded ACE score that includes being spanked as a child and adult mental health outcomes by examining each ACE separately to determine the contribution of each ACE. Data were drawn from Wave II of the CDC-Kaiser ACE Study, consisting of 7465 adult members of Kaiser Permanente in southern California. Dichotomous variables corresponding to each of the 11 ACE categories were created, with ACE score ranging from 0 to 11 corresponding to the total number of ACEs experienced. Multiple logistic regression modeling was used to examine the relationship between ACEs and adult mental health outcomes adjusting for sociodemographic covariates. Results indicated a graded dose-response relationship between the expanded ACE score and the likelihood of moderate to heavy drinking, drug use, depressed affect, and suicide attempts in adulthood. In the adjusted models, being spanked as a child was significantly associated with all self-reported mental health outcomes. Over 80% of the sample reported exposure to at least one ACE, signifying the potential to capture experiences not previously considered by traditional ACE indices. The findings highlight the importance of examining both cumulative ACE scores and individual ACEs on adult health outcomes to better understand key risk and protective factors for future prevention efforts.

The World Health Organization initiative to eliminate mother-to-child transmission of syphilis aims for ≥ 90% of pregnant women to be tested for syphilis and ≥ 90% to receive treatment by 2015. We calculated global and regional estimates of syphilis in pregnancy and associated adverse outcomes for 2008, as well as antenatal care (ANC) coverage for women with syphilis. Estimates were based upon a health service delivery model. National syphilis seropositivity data from 97 of 193 countries and ANC coverage from 147 countries were obtained from World Health Organization databases. Proportions of adverse outcomes and effectiveness of screening and treatment were from published literature. Regional estimates of ANC syphilis testing and treatment were examined through sensitivity analysis. In 2008, approximately 1.36 million (range: 1.16 to 1.56 million) pregnant women globally were estimated to have probable active syphilis; of these, 80% had attended ANC. Globally, 520,905 (best case: 425,847; worst case: 615,963) adverse outcomes were estimated to be caused by maternal syphilis, including approximately 212,327 (174,938; 249,716) stillbirths (>28 wk) or early fetal deaths (22 to 28 wk), 91,764 (76,141; 107,397) neonatal deaths, 65,267 (56,929; 73,605) preterm or low birth weight infants, and 151,547 (117,848; 185,245) infected newborns. Approximately 66% of adverse outcomes occurred in ANC attendees who were not tested or were not treated for syphilis. In 2008, based on the middle case scenario, clinical services likely averted 26% of all adverse outcomes. Limitations include missing syphilis seropositivity data for many countries in Europe, the Mediterranean, and North America, and use of estimates for the proportion of syphilis that was "probable active," and for testing and treatment coverage. Syphilis continues to affect large numbers of pregnant women, causing substantial perinatal morbidity and mortality that could be prevented by early testing and treatment

Authentic leadership and nurse-assessed adverse patient outcomes.

Wong, Carol A; Giallonardo, Lisa M

2013-07-01

Our purpose was to test a model examining relationships among authentic leadership, nurses' trust in their manager, areas of work life and nurse-assessed adverse patient outcomes. Although several work environment factors have been cited as critical to patient outcomes, studies linking nursing leadership styles with patient outcomes are limited suggesting the need for additional research to investigate the mechanisms by which leadership may influence patient outcomes. Secondary analysis of data collected in a cross-sectional survey of 280 (48% response rate) registered nurses working in acute care hospitals in Ontario was conducted using structural equation modelling. The final model fit the data acceptably (χ(2) = 1.30, df = 2, P = 0.52, IFI = 0.99, CFI = 1.00, RMSEA = 0.00). Authentic leadership was significantly associated with decreased adverse patient outcomes through trust in the manager and areas of work life. The findings suggest that nurses who see their managers as demonstrating high levels of authentic leadership report increased trust, greater congruence in the areas of work life and lower frequencies of adverse patient outcomes. Managers who emphasize transparency, balanced processing, self-awareness and high ethical standards in their interactions with nurses may contribute to safer work environments for patients and nurses. © 2013 John Wiley & Sons Ltd.

Nicotine exposure during pregnancy through cigarette smoking, nicotine replacement therapies or e-cigarette use continues to be a widespread public health problem, impacting both fetal and postnatal health. Yet, at this time, there remains limited data regarding the safety and efficacy in using these nicotine products during pregnancy. Notably, reports assessing the effect of nicotine exposure on postnatal health outcomes in humans, including reproductive health, are severely lacking. Our current understanding regarding the consequences of nicotine exposure during pregnancy is limited to a few animal studies, which do not comprehensively address the underlying cellular mechanisms involved. This paper aims to critically review the current knowledge from human and animal studies regarding the direct and indirect effects (e.g. obesity) of maternal nicotine exposure, regardless of its source, on reproductive outcomes in pregnancy and postnatal life. Furthermore, this review highlights several key cellular mechanisms involved in these adverse reproductive deficits including oxidative stress, inflammation, and endoplasmic reticulum (ER) stress. By understanding the interplay of the cellular mechanisms involved, further strategies could be developed to prevent the reproductive abnormalities resulting from exposure to nicotine in utero and influence informed clinical guidelines for pregnant women. © 2015 Society for Reproduction and Fertility.

Ongoing honey bee colony losses are of significant international concern because of the essential role these insects play in pollinating staple food crops. Chemical and non-chemical stressors both have been implicated as possible contributors to colony failure, however, the potential role of commonly-used neonicotinoid insecticides has emerged as particularly concerning. Neonicotinoids act on the nicotinic acetylcholine receptor (nAChR) to eliminate target pest insects, however, mounting evidence indicates that these chemicals may adversely affect beneficial pollinators, such as the honey bee, via impacts on learning and memory thereby affecting foraging success. However, the mechanisms linking activation of the nAChR to adverse effects on learning and memory are uncertain. Additionally, clear connections between observed impacts on individual bees and colony level effects are lacking. Therefore, the objective of this work was to develop adverse outcome pathways (AOPs) as a means to evaluate the biological plausibility and empirical evidence supporting (or refuting) the linkage between the nAChR and colony level impacts. Development of these AOPs has led to the identification of research gaps which, for example, may be of high priority in understanding how perturbation of pathways involved in neurotransmission can adversely affect honey bee health, causing colony instability and further failure. From this effort, an AOP network also was developed, laying the f

Unconventional oil and gas operations using hydraulic fracturing can contaminate surface and groundwater with endocrine-disrupting chemicals. We have previously shown that 23 of 24 commonly used hydraulic fracturing chemicals can activate or inhibit the estrogen, androgen, glucocorticoid, progesterone, and/or thyroid receptors in a human endometrial cancer cell reporter gene assay and that mixtures can behave synergistically, additively, or antagonistically on these receptors. In the current study, pregnant female C57Bl/6 dams were exposed to a mixture of 23 commonly used unconventional oil and gas chemicals at approximately 3, 30, 300, and 3000 μg/kg·d, flutamide at 50 mg/kg·d, or a 0.2% ethanol control vehicle via their drinking water from gestational day 11 through birth. This prenatal exposure to oil and gas operation chemicals suppressed pituitary hormone concentrations across experimental groups (prolactin, LH, FSH, and others), increased body weights, altered uterine and ovary weights, increased heart weights and collagen deposition, disrupted folliculogenesis, and other adverse health effects. This work suggests potential adverse developmental and reproductive health outcomes in humans and animals exposed to these oil and gas operation chemicals, with adverse outcomes observed even in the lowest dose group tested, equivalent to concentrations reported in drinking water sources. These endpoints suggest potential impacts on fertility, as previously observed in the male siblings, which require careful assessment in future studies.

There is little to no scientific data about the health benefits or risks to participating in hot yoga, in particular distinguishing it from the practice of non-hot yoga. This study aims to provide some preliminary evidence about the risks and benefits of participating in hot yoga. Future studies will be able to build off the findings herein. This study utilized online survey software (Qualtrics) and recruited participants through convenience sampling (n = 157) by targeting yoga websites and online forums. As there is currently no known questionnaire that has been developed to assess the risks and benefits of hot yoga participation, an exploratory measure was designed to gain more detailed responses from participants. Descriptive epidemiological analyses we re conducted. Participants of hot yoga had a number of pre-existing health conditions. Both benefits and adverse outcomes were reported. The most frequently reported health benefits of hot yoga in this sample included increased flexibility (63%), improved mood (58%), increased fitness (43%), and improved stamina (42%). Just over half of the participants reported some sort of adverse event during a hot yoga session (n = 82). The most commonly reported adverse events included dizziness (60%), feeling light headed (61%), nausea (35%), and dehydration (34%), amongst others. Further study on the risks and benefits of hot yoga participation is required.

Although colposcopy is the leading follow-up option for women with abnormal cervical cytology, little is known about its psychological consequences. We performed a systematic review to examine: (1) what, if any, are the adverse psychological outcomes following colposcopy and related procedures; (2) what are the predictors of adverse psychological outcomes post-colposcopy; and (3) what happens to these outcomes over time. Five electronic databases (PubMed, PsychINFO, CINAHL, Web of Science, Scopus) were searched for studies published in English between January 1986 and February 2014. Eligible studies assessed psychological wellbeing at one or more time-points post-colposcopy. Two reviewers independently screened titles and abstracts. Full texts of potentially eligible papers were reviewed. Data were abstracted from, and a quality appraisal performed of, eligible papers. Twenty-three papers reporting 16 studies were eligible. Colposcopy and related procedures can lead to adverse psychological outcomes, particularly anxiety. Ten studies investigated predictors of adverse psychological outcomes; management type and treatment had no impact on this. Seven studies investigated temporal trends in psychological outcomes post-colposcopy; findings were mixed, especially in relation to anxiety and distress. Studies were methodologically heterogeneous. Follow-up investigations and procedures for abnormal cervical cytology can cause adverse psychological outcomes among women. However, little is known about the predictors of these outcomes or how long they persist. There is a need for a more standardised approach to the examination of the psychological impact of colposcopy, especially longer-term outcomes. Follow-up investigations for abnormal cervical cytology can cause adverse psychological outcome among women. © 2015 Royal College of Obstetricians and Gynaecologists.

2016-10-01

Syphilis infection in pregnancy is known to cause a number of severe adverse pregnancy outcomes, including second-trimester miscarriage, stillbirth, very pre-term delivery and neonatal death, in addition to congenital syphilis. A retrospective review of women with positive syphilis serology and a pregnancy outcome between 2005 and 2012 in Leeds, UK, was performed. In all, 57 cases of positive syphilis serology in pregnancy were identified: 24 with untreated syphilis treated in the current pregnancy (Group 1); seven with reported but unconfirmed prior treatment who were retreated (Group 2); and 26 adequately treated prior to pregnancy (Group 3). The rate of severe adverse pregnancy outcomes in Group 1 at 21% was significantly higher than the 0% outcome of Group 3 (p = 0.02). The severe adverse pregnancy outcomes were two second-trimester miscarriages, two pre-term births at 25 and 28 weeks and one stillbirth at 32 weeks. There were no cases of term congenital syphilis or term neonatal death, but we observed high rates of other adverse pregnancy outcomes despite treatment during pregnancy. Rapid referral for treatment is needed before 18 weeks in order to minimise adverse pregnancy outcomes. © The Author(s) 2016.

The health care work environment and adverse health and safety consequences for nurses.

2010-01-01

Nurses' working conditions are inextricably linked to the quality of care that is provided to patients and patients' safety. These same working conditions are associated with health and safety outcomes for nurses and other health care providers. This chapter describes aspects of the nursing work environment that have been linked to hazards and adverse exposures for nurses, as well as the most common health and safety outcomes of nursing work. We include studies from 2000 to the present by nurse researchers, studies of nurses as subjects, and studies of workers under similar working conditions that could translate to nurses' work environment. We explore a number of work organization factors including shift work and extended work hours, safety climate and culture, teamwork, and communication. We also describe environmental hazards, including chemical hazards (e.g., waste anesthetics, hazardous drugs, cleaning compounds) and airborne and bloodborne pathogen exposure. Nurses' health and safety outcomes include physical (e.g., musculoskeletal disorders, gastrointestinal, slips, trips and falls, physical assault) and psychosocial outcomes (e.g., burnout, work-family conflict). Finally, we present recommendations for future research to further protect nurses and all health care workers from a range of hazardous working conditions.

This review addresses epidemiological, public health, and social policy implications of categorizing young children and their adult female caregivers in the United States as food secure when they live in households with "marginal food security," as indicated by the U.S. Household Food Security Survey Module. Existing literature shows that households in the US with marginal food security are more like food-insecure households than food-secure households. Similarities include socio-demographic characteristics, psychosocial profiles, and patterns of disease and health risk. Building on existing knowledge, we present new research on associations of marginal food security with health and developmental risks in young children (<48 mo) and health in their female caregivers. Marginal food security is positively associated with adverse health outcomes compared with food security, but the strength of the associations is weaker than that for food insecurity as usually defined in the US. Nonoverlapping CIs, when comparing odds of marginally food-secure children's fair/poor health and developmental risk and caregivers' depressive symptoms and fair/poor health with those in food-secure and -insecure families, indicate associations of marginal food security significantly and distinctly intermediate between those of food security and food insecurity. Evidence from reviewed research and the new research presented indicates that households with marginal food security should not be classified as food secure, as is the current practice, but should be reported in a separate discrete category. These findings highlight the potential underestimation of the prevalence of adverse health outcomes associated with exposure to lack of enough food for an active, healthy life in the US and indicate an even greater need for preventive action and policies to limit and reduce exposure among children and mothers.

To evaluate hemoglobin (Hb) levels in pregnant women from different geographical regions from Peru; to establish anemia and erythrocytocis rates and to establish the role of Hb on adverse perinatal outcomes using the Perinatal Information System (PIS) database of Peruvian Ministry of Health. Data were obtained from 379,816 births of 43 maternity care units between 2000 and 2010. Anemia and erythrocytocis rates were determined in each geographical region as well as rates of adverse perinatal outcomes. To analyze data the STATA program (versión 10.0,Texas, USA) was used. The results were considered significant at p<0.01. Mild anemia rate was higher in the coast (25.8%) and low forest (26.2%). Moderate/severe anemia rate in low forest was 2.6% and at the coast was 1.0%. In the highland, the highest rate of moderate/severe anemia was in the southern highlands (0.6%). The highest rate of erythrocytocis was found in the central highland (23.7%), 11.9% in the southern highland and 9.5% in the north highland. Severe anemia and erythrocytocis were associated with adverse perinatal outcomes. There are differences by Peruvian geographical region in anemia rates. In the central highlands were found the highest rates of erythrocytocis due to hypoxia effect in the high altitudes; however in the southern highlands, erythrocytocis was lower. Severe anemia and erythrocytosis were associated with increased adverse perinatal outcomes.

2013-01-01

Background The World Health Organization initiative to eliminate mother-to-child transmission of syphilis aims for ≥90% of pregnant women to be tested for syphilis and ≥90% to receive treatment by 2015. We calculated global and regional estimates of syphilis in pregnancy and associated adverse outcomes for 2008, as well as antenatal care (ANC) coverage for women with syphilis. Methods and Findings Estimates were based upon a health service delivery model. National syphilis seropositivity data from 97 of 193 countries and ANC coverage from 147 countries were obtained from World Health Organization databases. Proportions of adverse outcomes and effectiveness of screening and treatment were from published literature. Regional estimates of ANC syphilis testing and treatment were examined through sensitivity analysis. In 2008, approximately 1.36 million (range: 1.16 to 1.56 million) pregnant women globally were estimated to have probable active syphilis; of these, 80% had attended ANC. Globally, 520,905 (best case: 425,847; worst case: 615,963) adverse outcomes were estimated to be caused by maternal syphilis, including approximately 212,327 (174,938; 249,716) stillbirths (>28 wk) or early fetal deaths (22 to 28 wk), 91,764 (76,141; 107,397) neonatal deaths, 65,267 (56,929; 73,605) preterm or low birth weight infants, and 151,547 (117,848; 185,245) infected newborns. Approximately 66% of adverse outcomes occurred in ANC attendees who were not tested or were not treated for syphilis. In 2008, based on the middle case scenario, clinical services likely averted 26% of all adverse outcomes. Limitations include missing syphilis seropositivity data for many countries in Europe, the Mediterranean, and North America, and use of estimates for the proportion of syphilis that was “probable active,” and for testing and treatment coverage. Conclusions Syphilis continues to affect large numbers of pregnant women, causing substantial perinatal morbidity and mortality that

Objectives of this population-based study were: (1) to examine the relative contribution of childhood abuse and other adverse childhood experiences to poor adult health and increased health care utilization and (2) to examine the cumulative effects of adverse childhood experiences on adult health and health care utilization. Data from the Ontario Health Survey, a representative population sample (n=9,953) of respondents aged 15 years and older, were analyzed using logistic regression. Adverse childhood experiences examined were childhood physical and sexual abuse, parental marital conflict, poor parent-child relationship, low parental education and parental psychopathology. Most (72%) respondents reported at least one adverse childhood experience and a considerable proportion of respondents (37%) reported two or more of these experiences. In examining the bivariate models, childhood physical and sexual abuse had a stronger influence than other types of adverse childhood experiences. With the addition of other adverse childhood experiences in the model, the odds ratios for childhood abuse were attenuated but remained statistically significant for most health outcomes. This suggests that childhood abuse may have a unique adverse influence on the development of poor adult health. When an aggregate variable was created to explore the cumulative effects of adverse childhood experience, the odds were increased, with each additional experience, for reporting multiple health problems [odds ratio (OR): 1.22], poor self-rated health (OR: 1.18), pain (OR: 1.24), disability (OR: 1.24), general practitioner use (OR: 1.12), emergency room use (OR: 1.29) and health professional use (OR: 1.19). This study suggests that childhood abuse and other adverse childhood experiences are overlapping risk factors for long-term adult health problems and that the accumulation of these adverse experiences increases the risk of poor adult health. This study highlights the importance of the many

Established following a 1998 directive, the Department of Defense Birth and Infant Health Registry (Registry) team conducts surveillance of select reproductive health outcomes among military families. Data are compiled from the Military Health System Data Repository and Defense Manpower Data Center to define the Registry cohort and outcomes of interest. Outcomes are defined using ICD-9/ICD-10 and Current Procedural Terminology codes, and include: pregnancy outcomes (e.g., live births, losses), birth defects, preterm births, and male:female infant sex ratio. This report includes data from 2003-2014 on 1,304,406 infants among military families and 258,332 pregnancies among active duty women. Rates of common adverse infant and pregnancy outcomes were comparable to or lower than those in the general US population. These observations, along with prior Registry analyses, provide reassurance that military service is not independently associated with increased risks for select adverse reproductive health outcomes. The Registry's diverse research portfolio demonstrates its unique capabilities to answer a wide range of questions related to reproductive health. These data provide the military community with information to identify successes and areas for improvement in prevention and care.

Adverse Outcome Pathways: From Research to Regulation ...

EPA Pesticide Factsheets

An adverse outcome pathway (AOP) organizes existing knowledge on chemical mode of action, starting with a molecular initiating event such as receptor binding, continuing through key events, and ending with an adverse outcome such as reproductive impairment. AOPs can help identify knowledge gaps where more research is needed to understand the underlying mechanisms, aid in chemical hazard characterization, and guide the development of new testing approaches that use fewer or no animals. A September 2014 workshop co-sponsored by NICEATM and PCRM considered how the AOP concept could improve regulatory assessments of chemical toxicity. Scientists from 21 countries, representing industry, academia, regulatory agencies, and special interest groups, attended the workshop, titled Adverse Outcome Pathways: From Research to Regulation. Workshop plenary presentations were followed by breakout sessions that considered regulatory acceptance of AOPs and AOP-based tools, criteria for building confidence in an AOP for regulatory use, and requirements to build quantitative AOPs and AOP networks. Discussions during the closing session emphasized a need to increase transparent and inclusive collaboration, especially with disciplines outside of toxicology. Additionally, to increase impact, working groups should be established to systematically prioritize and develop AOPs. Multiple collaborative projects and follow-up activities resulted from the workshop. This manuscript provides a

The Obstetrics Adverse Outcomes Index was designed to measure the quality of perinatal care and includes 10 adverse events that may occur at or around the time of delivery. We hypothesized that adverse outcomes in the labor and delivery suite, including hypoxic ischemic encephalopathy, could be decreased with a combination of interventions, even among high-risk pregnancies. The objective of the study was to evaluate the impact of a labor and delivery care bundle on adverse obstetrics outcomes as measured by a modified Obstetrics Adverse Outcomes Index, Weighted Adverse Outcomes Index, and Severity Index. This is a retrospective cohort study including all women who delivered at our academic, tertiary care institution over a 3 year period of time, before and after the implementation of an intervention to decrease adverse outcomes. Outcome measures consisted of previously reported indices that were modified including the addition of hypoxic ischemic encephalopathy. The adverse outcomes index is a percentage of deliveries with 1 or more adverse events, the weighted adverse outcomes index is the sum of the points assigned to cases with adverse outcomes divided by the number of deliveries, and the severity index is the sum of the adverse outcome scores divided by the number of deliveries with an identified adverse outcome. A segmented regression analysis was utilized to evaluate the differences in the level and trend of each index before and after our intervention using calendar month as the unit of analysis. During the study period, 5826 deliveries met inclusion criteria. Comparing the pre- and postintervention periods, high-risk pregnancy was more common in the postintervention period (73.5% vs 79.4%, P < .001). Overall, there was a decrease in both the Modified Weighted Adverse Outcomes Index (P = .0497) and the Modified Severity Index (P = 0.01) comparing the pre- and postintervention periods; there was no difference in the Modified Adverse Outcomes Index (P = .43

2014-01-01

Cumulative adversity (CA) increases stress sensitivity and risk of adverse health outcomes. However, neural mechanisms underlying these associations in humans remain unclear. To understand neural responses underlying the link between CA and adverse health symptoms, the current study assessed brain activity during stress and neutral-relaxing states in 75 demographically matched, healthy individuals with high, mid, and low CA (25 in each group), and their health symptoms using the Cornell Medical Index. CA was significantly associated with greater adverse health symptoms (P=0.01) in all participants. Functional magnetic resonance imaging results indicated significant associations between CA scores and increased stress-induced activity in the lateral prefrontal cortex, insula, striatum, right amygdala, hippocampus, and temporal regions in all 75 participants (p<0.05, whole-brain corrected). In addition to these regions, the high vs low CA group comparison revealed decreased stress-induced activity in the medial orbitofrontal cortex (OFC) in the high CA group (p<0.01, whole-brain corrected). Specifically, hypoactive medial OFC and hyperactive right hippocampus responses to stress were each significantly associated with greater adverse health symptoms (p<0.01). Furthermore, an inverse correlation was found between activity in the medial OFC and right hippocampus (p=0.01). These results indicate that high CA sensitizes limbic–striatal responses to acute stress and also identifies an important role for stress-related medial OFC and hippocampus responses in the effects of CA on increasing vulnerability to adverse health consequences.

Prostate cancer outcomes in France: treatments, adverse effects and two-year mortality

PubMed Central

2014-01-01

Background This very large population-based study investigated outcomes after a diagnosis of prostate cancer (PCa) in terms of mortality rates, treatments and adverse effects. Methods Among the 11 million men aged 40 years and over covered by the general national health insurance scheme, those with newly managed PCa in 2009 were followed for two years based on data from the national health insurance information system (SNIIRAM). Patients were identified using hospitalisation diagnoses and specific refunds related to PCa and PCa treatments. Adverse effects of PCa treatments were identified by using hospital diagnoses, specific procedures and drug refunds. Results The age-standardised two-year all-cause mortality rate among the 43,460 men included in the study was 8.4%, twice that of all men aged 40 years and over. Among the 36,734 two-year survivors, 38% had undergone prostatectomy, 36% had been treated by hormone therapy, 29% by radiotherapy, 3% by brachytherapy and 20% were not treated. The frequency of treatment-related adverse effects varied according to age and type of treatment. Among men between 50 and 69 years of age treated by prostatectomy alone, 61% were treated for erectile dysfunction and 24% were treated for urinary disorders. The frequency of treatment for these disorders decreased during the second year compared to the first year (erectile dysfunction: 41% vs 53%, urinary disorders: 9% vs 20%). The frequencies of these treatments among men treated by external beam radiotherapy alone were 7% and 14%, respectively. Among men between 50 and 69 years with treated PCa, 46% received treatments for erectile dysfunction and 22% for urinary disorders. For controls without PCa but treated surgically for benign prostatic hyperplasia, these frequencies were 1.5% and 6.0%, respectively. Conclusions We report high survival rates two years after a diagnosis of PCa, but a high frequency of PCa treatment-related adverse effects. These frequencies remain

Stress and resource pathways connecting early socioeconomic adversity to young adults' physical health risk.

Although research has established the impact of early stress, including stressful life contexts, and early resources, such as educational attainment, on various adolescent health outcomes, previous research has not adequately investigated "integrative models" incorporating both stress and resource mediational pathways to explain how early socioeconomic adversity impacts physical health outcomes, particularly in early life stages. Data on early childhood/adolescent stress and socioeconomic resources as well as biomarkers indicating physical health status in young adulthood were collected from 11,798 respondents (54 % female) over a 13-year period from youth participating in the National Study of Adolescent Health (Add Health). Physical health risk in young adulthood was measured using a composite index of nine regulatory biomarkers of cardiovascular and metabolic systems. Heterogeneity in stress and socioeconomic resource pathways was assessed using latent class analysis to identify clusters, or classes, of stress and socioeconomic resource trajectories. The influence of early socioeconomic adversity on young adults' physical health risk, as measured by biomarkers, was estimated, and the role of stress and socioeconomic resource trajectory classes as linking mechanisms was assessed. There was evidence for the influence of early socioeconomic adversity on young adults' physical health risk directly and indirectly through stress and socioeconomic resource trajectory classes over the early life course. These findings suggest that health models should be broadened to incorporate both stress and resource experiences simultaneously. Furthermore, these findings have prevention and intervention implications, including the importance of early socioeconomic adversity and key intervention points for "turning" the trajectories of at-risk youth.

This study describes the prevalence of childhood traumatic events (CTEs) among adults with comorbid substance use disorders (SUDs) and mental health problems (MHPs) and assesses the relation between cumulative CTEs and adult health outcomes. Adults with SUDs/MHPs (N=402) were recruited from residential treatment programs and interviewed at treatment admission. Exposures to 9 types of adverse childhood experiences were summed and categorized into 6 ordinal levels of exposure. Descriptive analyses were conducted to assess the prevalence and range of exposure to CTEs in comparison with a sample from primary health care. Logistic regression analyses were conducted to examine the association between the cumulative exposure to CTEs and adverse health outcomes. Most of the sample reported exposure to CTEs, with higher exposure rates among the study sample compared with the primary health care sample. Greater exposure to CTEs significantly increased the odds of several adverse adult outcomes, including PTSD, alcohol dependence, injection drug use, tobacco use, sex work, medical problems, and poor quality of life. Study findings support the importance of early prevention and intervention and provision of trauma treatment for individuals with SUDs/MHPs.

2018-06-15

While increased rheumatic disease activity during pregnancy has been associated with adverse pregnancy outcomes, this activity is typically assessed by the physician. Little is known, however, about the association between patient-reported measures of disease activity and pregnancy outcomes. Univariate and multivariable regression models were used to assess the relationship between patient and physician-reported measures of disease activity and adverse pregnancy outcomes in 225 patients with lupus or rheumatoid arthritis (RA) enrolled in a prospective registry at a single academic center from 2008-2016. In women with RA, patient-reported disease activity is associated with preterm birth (OR 5.9 (1.5-23.9)), and gestational age (beta -1.5 weeks (-2.6, -0.4 weeks)). The physician assessment of disease activity also predicted preterm (OR 2.1 (1.2-3.5)), small for gestational age births (OR 1.8 (1.03-3.1), and gestational age in weeks (beta -0.6 weeks (-0.9, -0.02 weeks)). On the other hand, SLE patient-reported disease activity measures, including the HAQ, pain or global health measures, are not associated with adverse pregnancy outcomes. However, physician measures of SLE disease activity are associated with preterm birth (OR 2.9 (1.-6.3)), cesarean delivery (OR 2.3 (1.0-5.3)), and preeclampsia (OR 2.8 (1.3-6.3)). The results do not appear to be driven by lupus nephritis or antiphospholipid syndrome. For women with RA, patient-reported measures of disease activity may be useful adjuncts to physician-reported measures in identifying pregnancies at greater risk. In contrast, in SLE, no patient-reported measures were associated with adverse outcomes while physician measures of disease activity helped predict several adverse pregnancy outcomes.

To investigate the severe adverse pregnancy outcomes in pregnancies with placenta previa and prior cesarean delivery and its risk factors. This retrospective casecontrol study reviewed all pregnancies with placenta previa and prior cesarean delivery delivered by repeat cesarean section in our institution between January 2005 and June 2015,and investigated the incidence of severe adverse pregnancy outcome. A composite of severe adverse pregnancy outcomes (including transfusion of 10 units or more red blood cells,maternal ICU admission,unanticipated injuries,repeat operation,hysterectomy,and maternal death) and other maternal and neonatal outcomes were described. Univariate and multivariable logistic regression analysis were used to quantify the effects of risk factors on severe adverse pregnancy outcomes. There were 478 women with placenta previa and prior cesarean delivery in our hospital over the last decade. The average age of them was 32.5±4.8 years old,most women were beyond 30 years old,the average gravidity and parity were 4 and 1,131 cases (27.4%) had severe adverse pregnancy outcomes. Transfusion of 10 units or more red blood cells happened in 75 cases (15.7%,75/478); 44 cases (9.2%,44/478) necessitated maternal ICU admission; unanticipated bladder injury occurred in 11 cases,but non ureter or bowel injury happened; All 4 repeat operations were due to delayed hemorrhage after conservative management during cesarean delivery,and an emergent hysterectomy was performed for all of the 4 cases. Hysterectomy (107 cases,22.4%) was the most common severe adverse pregnancy outcome. Among all 311 morbidly adherent placenta cases finally confirmed by pathological or surgical findings or both,only 172 (55.3%) were suspected before delivery. Multivariable logistic regression analysis showed that the risk of severe adverse pregnancy outcomes was significantly increased by pernicious placenta previa (i.e. anterior placenta overlying the prior cesarean scar),suspicion of

Although cigarette smoking remains the most prevalent form of tobacco use in girls and in women of reproductive age globally, use of non-cigarette forms of tobacco is prevalent or gaining in popularity in many parts of the world, especially in low- and middle-income countries. Sparse but growing evidence suggests that the use of some non-cigarette tobacco products during pregnancy increases the risk of adverse pregnancy outcomes. In this paper we review the literature on the prevalence of non-cigarette tobacco product use in pregnant women and in women of reproductive age in high-, middle-, and low-income countries and the evidence that maternal use of these products during pregnancy has adverse health effects. In addition, we communicate findings from an international group of perinatal and tobacco experts that was convened to establish research priorities concerning the use of non-cigarette tobacco products during pregnancy. The working group concluded that attempts to develop a public health response to non-cigarette tobacco use in women are hindered by a lack of data on the epidemiology of use in many parts of the world and by our limited understanding of the type and magnitude of the health effects of these products. We highlight research gaps and provide recommendations for a global research agenda. PMID:20225987

We examine whether intersectionality theory—which formalizes the notion that adverse health outcomes owing to having a marginalized social status, identity, or characteristic, may be magnified for individuals with an additional marginalized social status, identity, or characteristic —can be applied using quantitative methods to describe the differential effects of poverty on alcohol consumption across sex and race/ethnicity. Using the National Epidemiologic Survey on Alcohol and Related Conditions, we analyze longitudinal data from Black, Hispanic, and White drinkers (n = 21,140) to assess multiplicative interactions between poverty, as defined by the U.S. Census Bureau, sex, and race/ethnicity, on adverse alcohol outcomes. Findings indicated that the effect of poverty on the past-year incidence of heavy episodic drinking was stronger among Black men and Black women in comparison to men and women of other racial/ethnic groups. Poverty reduction programs that are culturally informed may help reduce racial/ethnic disparities in the adverse outcomes of alcohol consumption. PMID:28349171

This review addresses epidemiological, public health, and social policy implications of categorizing young children and their adult female caregivers in the United States as food secure when they live in households with “marginal food security,” as indicated by the U.S. Household Food Security Survey Module. Existing literature shows that households in the US with marginal food security are more like food-insecure households than food-secure households. Similarities include socio-demographic characteristics, psychosocial profiles, and patterns of disease and health risk. Building on existing knowledge, we present new research on associations of marginal food security with health and developmental risks in young children (<48 mo) and health in their female caregivers. Marginal food security is positively associated with adverse health outcomes compared with food security, but the strength of the associations is weaker than that for food insecurity as usually defined in the US. Nonoverlapping CIs, when comparing odds of marginally food-secure children’s fair/poor health and developmental risk and caregivers’ depressive symptoms and fair/poor health with those in food-secure and -insecure families, indicate associations of marginal food security significantly and distinctly intermediate between those of food security and food insecurity. Evidence from reviewed research and the new research presented indicates that households with marginal food security should not be classified as food secure, as is the current practice, but should be reported in a separate discrete category. These findings highlight the potential underestimation of the prevalence of adverse health outcomes associated with exposure to lack of enough food for an active, healthy life in the US and indicate an even greater need for preventive action and policies to limit and reduce exposure among children and mothers.

Objective To determine whether UK obstetric trainees transitioning from directly to indirectly-supervised practice have a higher likelihood of adverse patient outcomes from operative deliveries compared to other indirectly supervised trainees and to examine whether performing more procedures under direct supervision is associated with fewer adverse outcomes in initial indirect practice. Methods We examined all deliveries (13,861) conducted by obstetricians at a single centre over 5 years (2008-2013). Mixed-effects logistic regression models were used to compare estimated blood loss, maternal trauma, umbilical arterial pH, delayed neonatal respiration, failed instrumental delivery, and critical incidents for trainees in their first indirectly-supervised year with trainees in all other years of indirect practice. Outcomes for trainees in their first indirectly-supervised 3 months were compared to their outcomes for the remainder of the year. Linear regression was used to examine the relationship between number of procedures performed under direct supervision and initial outcomes under indirect supervision. Results Trainees in their first indirectly-supervised year had a higher likelihood of >2 litres estimated blood loss at any delivery (OR 1.32;CI(1.01-1.64) p<0.05) and of failed instrumental delivery (OR 2.33;CI(1.37-3.29) p<0.05) compared with other indirectly-supervised trainees. Other measured outcomes showed no significant differences. Within the first three months of indirect supervision, the likelihood of operative vaginal deliveries with >1litre estimated blood loss (OR 2.54;CI(1.88-3.20) p<0.05) was higher compared to the remainder of the first year. Performing more deliveries under direct supervision prior to beginning indirectly-supervised training was associated with decreased risk of >1litre estimated blood loss (p<0.05). Conclusions Obstetric trainees in their first year of indirectly-supervised practice have a higher likelihood of immediate adverse

We examined methodological issues in studies of disaster-related effects on reproductive health outcomes and fertility among women of reproductive age and infants in the United States (US). We conducted a systematic literature review of 1,635 articles and reports published in peer-reviewed journals or by the government from January 1981 through December 2010. We classified the studies using three exposure types: (1) physical exposure to toxicants; (2) psychological trauma; and (3) general exposure to disaster. Fifteen articles met our inclusion criteria concerning research focus and design. Overall studies pertained to eight different disasters, with most (n = 6) focused on the World Trade Center attack. Only one study examined pregnancy loss, i.e., occurrence of spontaneous abortions post-disaster. Most studies focused on associations between disaster and adverse birth outcomes, but two studies pertained only to post-disaster fertility while another two examined it in addition to adverse birth outcomes. In most studies disaster-affected populations were assumed to have experienced psychological trauma, but exposure to trauma was measured in only four studies. Furthermore, effects of both physical exposure to toxicants and psychological trauma on disaster-affected populations were examined in only one study. Effects on birth outcomes were not consistently demonstrated, and study methodologies varied widely. Even so, these studies suggest an association between disasters and reproductive health and highlight the need for further studies to clarify associations. We postulate that post-disaster surveillance among pregnant women could improve our understanding of effects of disaster on the reproductive health of US pregnant women. PMID:22752348

Background The World Health Organization guidelines recommend cotrimoxazole prophylactic treatment (CPT) for all HIV-exposed infants from age 6 weeks to the cessation of breastfeeding and the exclusion of HIV infection. There are limited data about the effects of CPT among this population of infants. We examined the effects of CPT on adverse health outcomes among HIV-exposed infants during the first 36 weeks of life by using data from the Breastfeeding, Antiretrovirals, and Nutrition (BAN) study, a large clinical trial of antiretroviral drugs given to the mother or infant for prevention of HIV transmission during breastfeeding. Methods For the analysis, we assigned a status of CPT-exposed to infants who were participating in the study after the CPT program started. We estimated unadjusted and adjusted hazard ratios (HRs) for the effect of CPT status on time to incident malaria, severe illness or death, anemia, and weight-for-age Z score < −2.0. Participation in the study was limited to focus exclusively on HIV-exposed, uninfected infants. Results The HR for the effect of CPT on incident malaria was 0.35 (95% confidence interval [CI]: 0.21, 0.57) during the first 10 weeks of CPT exposure, and 0.93 (95% CI: 0.67, 1.29) for the remaining 20 weeks. CPT was not associated with the other outcomes examined. Conclusions CPT offered temporary protection against malaria among HIV-exposed, uninfected infants. However, CPT offered no protection against anemia, low weight for age, or the collapsed outcome of severe illness or death. PMID:22801093

Immigrants to Western countries increasingly originate from countries with pervasive gender inequalities, where women experience disproportionately high rates of threats to their well-being. Health and social services in countries of settlement encounter several adverse outcomes linked to gender bias among immigrant groups. Little is known about interventions implemented to address manifestations of gender bias among immigrant populations. A scoping review was undertaken to describe the literature on existing interventions and determine knowledge gaps. Nine academic and grey literature databases were searched for literature, with four reviewers screening the results. Of the 29 included reports, most targeted domestic violence amongst the Latino population in the United States, with few interventions focusing on other outcomes, populations, and settings. The majority reported achieving their objective, although 13 interventions were not evaluated. Future research and practice to address gender bias among immigrants may benefit from expanding on ethnic diversity, designing and reporting evaluations, addressing the context of gender inequities, tailoring to local community needs, and engaging community-based groups.

To examine the influence of nausea and vomiting of pregnancy (NVP) on pregnancy outcomes. Outcomes were compared for primigravidas with a current singleton gestation enrolled at <20 weeks' gestation in a maternity risk screening and education program (n = 81 486). Patient-reported maternal characteristics and pregnancy outcomes were compared for women with and without NVP and within the NVP group for those with and without poor weight gain. 6.4% of women reported NVP as a pregnancy complication. Women reporting NVP were more likely to be younger, obese, single and smoke. They had higher rates of preterm delivery, pregnancy-induced hypertension and low birth weight <2500 g. Almost one-quarter of women with NVP had lower than recommended weight gain. Poor weight gain was associated with a higher incidence of adverse outcomes. Obesity, tobacco use and poor pregnancy weight gain independently increased the odds of an adverse outcome. NVP and subsequent poor weight gain may be associated with adverse pregnancy outcomes.

Early life adversity reduces stress reactivity and enhances impulsive behavior: Implications for health behaviors

PubMed Central

Lovallo, William R.

2012-01-01

Altered reactivity to stress, either in the direction of exaggerated reactivity or diminished reactivity, may signal a dysregulation of systems intended to maintain homeostasis and a state of good health. Evidence has accumulated that diminished reactivity to psychosocial stress may signal poor health outcomes. One source of diminished cortisol and autonomic reactivity is the experience of adverse rearing during childhood and adolescence. The Oklahoma Family Health Patterns Project has examined a cohort of 426 healthy young adults with and without a family history of alcoholism. Regardless of family history, persons who had experienced high degrees of adversity prior to age 16 had a constellation of changes including reduced cortisol and heart rate reactivity, diminished cognitive capacity, and unstable regulation of affect, leading to behavioral impulsivity and antisocial tendencies. We present a model whereby this constellation of physiological, cognitive, and affective tendencies is consistent with altered central dopaminergic activity leading to changes in brain function that may foster impulsive and risky behaviors. These in turn may promote greater use of alcohol other drugs along with adopting poor health behaviors. This model provides a pathway from early life adversity to low stress reactivity that forms a basis for risky behaviors and poor health outcomes. PMID:23085387

Anaemia in pregnant women is a public health problem, especially in developing countries. The aim of this study was to assess the prevalence and related risk factors of anaemia during pregnancy in a large multicentre retrospective study (n = 44,002) and to determine the adverse pregnancy outcomes in women with or without anaemia. The study is a secondary data analysis of a retrospective study named "Gestational diabetes mellitus Prevalence Survey (GPS) study in China". Structured questionnaires were used to collect socio-demographic characteristics, haemoglobin levels and pregnancy outcomes from all the participants. Anaemia in pregnancy is defined as haemoglobin < 110 g/L. We used SPSS software to assess the predictors of anaemia and associated adverse pregnancy outcomes. The overall prevalence of anaemia was 23.5%. Maternal anaemia was significantly associated with maternal age ≥ 35 years (AOR = 1.386), family per capita monthly income< 1000 CNY (AOR = 1.671), rural residence (AOR = 1.308) and pre-pregnancy BMI < 18.5 kg/m 2 (AOR = 1.237). Adverse pregnancy outcomes, including GDM, polyhydramnios, preterm birth, low birth weight (< 2500 g), neonatal complications and NICU admission, increased significantly (P < 0.001) in those with anaemia than those without. The results indicated that anaemia continues to be a severe health problem among pregnant women in China. Anaemia is associated with adverse pregnancy outcomes. Pregnant women should receive routine antenatal care and be given selective iron supplementation when appropriate.

Low and high birthweight is known to increase the risk of acute and longer-term adverse outcomes, such as stillbirth, infant mortality, obesity, type 2 diabetes and cardiovascular diseases. Gestational dyslipidaemia is associated with a numbers of adverse birth outcomes, but evidence regarding birthweight is still inconsistent to reliably inform clinical practice and treatment recommendations. The aim of this study was to explore the relationship between maternal gestational dyslipidaemia and neonatal health outcomes, namely, birthweight, metabolic factors and inflammatory parameters. We searched systematically Embase, MEDLINE, PubMed, CINAHL Plus and Cochrane Library up to 1 August 2016 (with an updated search in MEDLINE at the end of July 2017) for longitudinal studies that assessed the association of maternal lipid levels during pregnancy with neonatal birthweight, or metabolic and inflammatory parameters up to 3 years old. Data from 46 publications including 31,402 pregnancies suggest that maternal high triglycerides and low high-density-lipoprotein cholesterol levels throughout pregnancy are associated with increased birthweight, higher risk of large for gestational age and macrosomia and lower risk of small-for-gestational age. The findings were consistent across the studied populations, but stronger associations were observed in women who were overweight or obese prior to pregnancy. This meta-analysis suggested that the potential under-recognized adverse effects of intrauterine exposure to maternal dyslipidaemia may warrant further investigation into the relationship between maternal dyslipidaemia and birthweight in large prospective cohorts or in randomized trials. © 2018 World Obesity Federation.

Research on predictors of adverse birth outcomes has focused on maternal characteristics. Much less is known about the role of paternal factors. Paternal education is an important socioeconomic marker that may predict birth outcomes over and above maternal socioeconomic indicators. Using data from the 2006 Canadian Birth-Census Cohort, we estimated the associations between paternal education and preterm birth, small-for-gestational-age (SGA) birth, stillbirth and infant mortality in Canada, controlling for maternal characteristics. Binomial regression was used to estimate risk ratios and risk differences for adverse birth outcomes associated with paternal education, after controlling for maternal education, age, marital status, parity, ethnicity and nativity. A total of 131 285 singleton births were included in the present study. Comparing the lowest to the highest paternal education category, adjusted risk ratios (95% CIs) were 1.22 (1.10 to 1.35) for preterm birth, 1.13 (1.03 to 1.23) for SGA birth, 1.92 (1.28 to 2.86) for stillbirth and 1.67 (1.01 to 2.75) for infant mortality. Consistent patterns of associations were observed for absolute risk differences. Our study suggests that low paternal education increases the risk of adverse birth outcomes, and especially of fetal and infant mortality, independently from maternal characteristics.

Although older adults with pre-dialysis chronic kidney disease (CKD) are at higher risk for falls, the prognostic significance of a serious fall injury prior to dialysis initiation has not been well described in the end-stage renal disease population. We examined the association between a serious fall injury in the year prior to starting hemodialysis and adverse health outcomes in the year following dialysis initiation using a retrospective cohort study of U.S. Medicare beneficiaries ≥ 67 years old who initiated dialysis in 2010-2012. Serious fall injuries were defined using diagnostic codes for falls plus an injury (fracture, joint dislocation, or head injury). Health outcomes, defined as time-to-event variables within the first year of dialysis, included four outcomes: a subsequent serious fall injury, hospital admission, post-acute skilled nursing facility (SNF) utilization, and mortality. Among this cohort of 81,653 initiating hemodialysis, 2,958 (3.6%) patients had a serious fall injury in the year prior to hemodialysis initiation. In the first year of dialysis, 7.6% had a subsequent serious fall injury, 67.6% a hospitalization, 30.7% a SNF claim and 26.1% died. Those with vs. without a serious fall injury in the year prior to hemodialysis initiation were at higher risk (hazard ratio, 95% confidence interval) for a subsequent serious fall injury (2.65, 2.41-2.91), hospitalization (1.11, 1.06-1.16), SNF claim (1.40, 1.30-1.50), and death (1.14, 1.06-1.22). For older adults initiating dialysis, a history of a serious fall injury may provide prognostic information to support decision-making and establish expectations for life after dialysis initiation.

Rheumatic fever and rheumatic heart disease remain important health problems in developing countries. Mitral stenosis (MS) is the most common form of rheumatic heart disease. The aim of this study was to investigate incidence and echocardiographic predictors of long-term adverse outcomes in patients with rheumatic mitral stenosis in sinus rhythm. We retrospectively reviewed medical records of patients diagnosed with isolated rheumatic MS of any severity at Siriraj Hospital between 1996 and 2013. Demographic data, echocardiographic data, and long-term adverse outcomes were collected. Long-term adverse outcomes included all-cause mortality, hospitalization due to heart failure, new-onset atrial fibrillation, and/or embolic stroke during follow-up. One hundred eighty five patients (aged 41.9 ± 13.2 years, 81.1% female) were included during the median follow-up period of 12.6 years (95% CI: 11.2-14.0). MS was classified as mild, moderate, and severe in 8.6%, 2 7.6%, and 63.8% of patients, respectively. Average mitral valve score was 8.25 ± 1.5. Most patients (61.6%) underwent percutaneous balloon mitral valvulotomy. Incidence of long-term adverse outcome was 43.2% (95% CI: 36.0-50.7%) and included mortality in two patients (1.1%, 95% CI: 0.13-3.9%), hospitalization due to heart failure in 20 patients (10.8%, 95% CI: 6.7-16.2%), new-onset atrial fibrillation in 71 patients (38.4%, 95% CI: 31.3-45.8%), and embolic stroke in 14 patients (7.6%, 95% CI: 4.2-12.4%). Echocardiographic parameters associated with long-term adverse outcomes were left atrial dimension greater than 50 mm (HR 2.61, 95% CI: 1.08-6.30; p = 0.03) and left ventricular end-systolic dimension less than 28 mm (HR 3.06, 95% CI: 1.25-7.49; p = 0.01). Long-term adverse outcomes are common in patients with rheumatic MS in sinus rhythm. Long-term adverse outcomes were found to correlate with left atrial dimension and left ventricular end-systolic dimension.

Intrauterine growth restriction accounts for a significant proportion of perinatal morbidity and mortality currently encountered in obstetric practice. The primary goal of antenatal care is the early recognition of such conditions to allow treatment and optimization of both maternal and fetal outcomes. Management of pregnancies complicated by intrauterine growth restriction remains one of the greatest challenges in obstetrics. Frequently, however, clinical evidence of underlying uteroplacental dysfunction may only emerge at a late stage in the disease process. With advanced disease the only therapeutic intervention is delivery of the fetus and placenta. The cerebroplacental ratio is gaining much interest as a useful tool in differentiating the at-risk fetus in both intrauterine growth restriction and the appropriate-for-gestational-age setting. The cerebroplacental ratio quantifies the redistribution of the cardiac output resulting in a brain-sparing effect. The Prospective Observational Trial to Optimize Pediatric Health in Intrauterine Growth Restriction group previously demonstrated that the presence of a brain-sparing effect is significantly associated with an adverse perinatal outcome in the intrauterine growth restriction cohort. The aim of the Prospective Observational Trial to Optimize Pediatric Health in Intrauterine Growth Restriction study was to evaluate the optimal management of fetuses with an estimated fetal weight <10th centile. The objective of this secondary analysis was to evaluate if normalizing cerebroplacental ratio predicts adverse perinatal outcome. In all, 1116 consecutive singleton pregnancies with intrauterine growth restriction completed the study protocol over 2 years at 7 centers, undergoing serial sonographic evaluation and multivessel Doppler measurement. Cerebroplacental ratio was calculated using the pulsatility and resistance indices of the middle cerebral and umbilical artery. Abnormal cerebroplacental ratio was defined as <1

Significant and persistent racial and income disparities in birth outcomes exist in the US. The analyses in this manuscript examine whether adverse birth outcome time trends and associations between area-level variables and adverse birth outcomes differ by urban-rural status. Alabama births records were merged with ZIP code-level census measures of race, poverty, and rurality. B-splines were used to determine long-term preterm birth (PTB) and low birth weight (LBW) trends by rurality. Logistic regression models were used to examine differences in the relationships between ZIP code-level percent poverty or percent African-American with either PTB or LBW. Interactions with rurality were examined. Population dense areas had higher adverse birth outcome rates compared to other regions. For LBW, the disparity between population dense and other regions increased during the 1991-2005 time period, and the magnitude of the disparity was maintained through 2010. Overall PTB and LBW rates have decreased since 2006, except within isolated rural regions. The addition of individual-level socioeconomic or race risk factors greatly attenuated these geographical disparities, but isolated rural regions maintained increased odds of adverse birth outcomes. ZIP code-level percent poverty and percent African American both had significant relationships with adverse birth outcomes. Poverty associations remained significant in the most population-dense regions when models were adjusted for individual-level risk factors. Population dense urban areas have heightened rates of adverse birth outcomes. High-poverty African American areas have higher odds of adverse birth outcomes in urban versus rural regions. These results suggest there are urban-specific social or environmental factors increasing risk for adverse birth outcomes in underserved communities. On the other hand, trends in PTBs and LBWs suggest interventions that have decreased adverse birth outcomes elsewhere may not be reaching

Overall PTB and LBW rates have decreased since 2006, except within isolated rural regions. The addition of individual-level socioeconomic or race risk factors greatly attenuated these geographical disparities, but isolated rural regions maintained increased odds of adverse birth outcomes. ZIP code-level percent poverty and percent African American both had significant relationships with adverse birth outcomes. Poverty associations remained significant in the most population-dense regions when models were adjusted for individual-level risk factors. Conclusions Population dense urban areas have heightened rates of adverse birth outcomes. High-poverty African American areas have higher odds of adverse birth outcomes in urban versus rural regions. These results suggest there are urban-specific social or environmental factors increasing risk for adverse birth outcomes in underserved communities. On the other hand, trends in PTBs and LBWs suggest interventions that have decreased adverse

Abstract Gestational diabetes mellitus (GDM) is a common disease in pregnancy causing maternal and fetal complications. To prevent these adverse outcomes, optimal screening and diagnostic criteria must be adequate, timely, and efficient. This study suggests a novel approach that is practical, efficient, and patient- and clinician-friendly in predicting adverse outcomes of GDM. The authors conducted a retrospective cohort study via medical record review of patients admitted between March 2001 and April 2013 at the Severance Hospital, Seoul, South Korea. Patients diagnosed by a conventional 2-step method were evaluated according to the presence of adverse outcomes (neonatal hypoglycemia, hyperbilirubinemia, and hyperinsulinemia; admission to the neonatal intensive care unit; large for gestational age; gestational insulin therapy; and gestational hypertension). Of 802 women who had an abnormal 50-g, 1-hour glucose challenge test, 306 were diagnosed with GDM and 496 did not have GDM (false-positive group). In the GDM group, 218 women (71.2%) had adverse outcomes. In contrast, 240 women (48.4%) in the false-positive group had adverse outcomes. Women with adverse outcomes had a significantly higher body mass index (BMI) at entry (P = 0.03) and fasting blood glucose (FBG) (P = 0.03). Our logistic regression model derived from 2 variables, BMI at entry and FBG, predicted GDM adverse outcome with an area under the curve of 0.642, accuracy of 61.3%, sensitivity of 57.2%, and specificity of 66.9% compared with the conventional 2-step method with an area under the curve of 0.610, accuracy of 59.1%, sensitivity of 47.6%, and specificity of 74.4%. Our model performed better in predicting GDM adverse outcomes than the conventional 2-step method using only BMI at entry and FBG. Moreover, our model represents a practical, inexpensive, efficient, reproducible, easy, and patient- and clinician-friendly approach. PMID:26735528

Unconventional oil and gas operations using hydraulic fracturing can contaminate surface and groundwater with endocrine-disrupting chemicals. We have previously shown that 23 of 24 commonly used hydraulic fracturing chemicals can activate or inhibit the estrogen, androgen, glucocorticoid, progesterone, and/or thyroid receptors in a human endometrial cancer cell reporter gene assay and that mixtures can behave synergistically, additively, or antagonistically on these receptors. In the current study, pregnant female C57Bl/6 dams were exposed to a mixture of 23 commonly used unconventional oil and gas chemicals at approximately 3, 30, 300, and 3000 μg/kg·d, flutamide at 50 mg/kg·d, or a 0.2% ethanol control vehicle via their drinking water from gestational day 11 through birth. This prenatal exposure to oil and gas operation chemicals suppressed pituitary hormone concentrations across experimental groups (prolactin, LH, FSH, and others), increased body weights, altered uterine and ovary weights, increased heart weights and collagen deposition, disrupted folliculogenesis, and other adverse health effects. This work suggests potential adverse developmental and reproductive health outcomes in humans and animals exposed to these oil and gas operation chemicals, with adverse outcomes observed even in the lowest dose group tested, equivalent to concentrations reported in drinking water sources. These endpoints suggest potential impacts on fertility, as previously observed in the male siblings, which require careful assessment in future studies. - See more at: http://press.endocrine.org/doi/10.1210/en.2016-1242#sthash.9kqfLvXg.dpuf

Adverse childhood experiences (ACEs; e.g. abuse, neglect, and parental loss) have been associated with increased risk for later-life disease and dysfunction using adults' retrospective self-reports of ACEs. Research should test whether associations between ACEs and health outcomes are the same for prospective and retrospective ACE measures. We estimated agreement between ACEs prospectively recorded throughout childhood (by Study staff at Study member ages 3, 5, 7, 9, 11, 13, and 15) and retrospectively recalled in adulthood (by Study members when they reached age 38), in the population-representative Dunedin cohort (N = 1,037). We related both retrospective and prospective ACE measures to physical, mental, cognitive, and social health at midlife measured through both objective (e.g. biomarkers and neuropsychological tests) and subjective (e.g. self-reported) means. Dunedin and U.S. Centers for Disease Control ACE distributions were similar. Retrospective and prospective measures of adversity showed moderate agreement (r = .47, p < .001; weighted Kappa = .31, 95% CI: .27-.35). Both associated with all midlife outcomes. As compared to prospective ACEs, retrospective ACEs showed stronger associations with life outcomes that were subjectively assessed, and weaker associations with life outcomes that were objectively assessed. Recalled ACEs and poor subjective outcomes were correlated regardless of whether prospectively recorded ACEs were evident. Individuals who recalled more ACEs than had been prospectively recorded were more neurotic than average, and individuals who recalled fewer ACEs than recorded were more agreeable. Prospective ACE records confirm associations between childhood adversity and negative life outcomes found previously using retrospective ACE reports. However, more agreeable and neurotic dispositions may, respectively, bias retrospective ACE measures toward underestimating the impact of adversity on objectively measured life outcomes and

Adverse childhood experiences and health anxiety in adulthood.

Childhood experiences are thought to predispose a person to the development of health anxiety later in life. However, there is a lack of research investigating the influence of specific adverse experiences (e.g., childhood abuse, household dysfunction) on this condition. The current study examined the cumulative influence of multiple types of childhood adversities on health anxiety in adulthood. Adults 18-59 years of age (N=264) completed a battery of measures to assess adverse childhood experiences, health anxiety, and associated constructs (i.e., negative affect and trait anxiety). Significant associations were observed between adverse childhood experiences, health anxiety, and associated constructs. Hierarchical multiple regression analysis indicted that adverse childhood experiences were predictive of health anxiety in adulthood; however, the unique contribution of these experience were no longer significant following the inclusion of the other variables of interest. Subsequently, mediation analyses indicated that both negative affect and trait anxiety independently mediated the relationship between adverse childhood experiences and health anxiety in adulthood. Increased exposure to adverse childhood experiences is associated with higher levels of health anxiety in adulthood; this relationship is mediated through negative affect and trait anxiety. Findings support the long-term negative impact of cumulative adverse childhood experiences and emphasize the importance of addressing negative affect and trait anxiety in efforts to prevent and treat health anxiety.

Adverse outcome pathways (AOPs) to enhance EDC ...

EPA Pesticide Factsheets

Screening and testing for endocrine active chemicals was mandated under 1996 amendments to the Safe Drinking Water Act and Food Quality Protection Act. Efficiencies can be gained in the endocrine disruptor screening program by using available biological and toxicological knowledge to facilitate greater use of high throughput screening data and other data sources to inform endocrine disruptor assessments. Likewise, existing knowledge, when properly organized, can help aid interpretation of test results. The adverse outcome pathway (AOP) framework, which organizes information concerning measureable changes that link initial biological interactions with a chemical to adverse effects that are meaningful to risk assessment and management, can aid this process. This presentation outlines the ways in which the AOP framework has already been employed to support EDSP and how it may further enhance endocrine disruptor assessments in the future.

Angiogenic factors are strongly associated with adverse maternal and fetal outcomes among women with preterm preeclampsia (PE) in developed countries. We evaluated the role of angiogenic factors and their relationship to adverse outcomes among Haitian women with PE. We measured plasma antiangiogenic soluble fms-like tyrosine kinase 1 (sFlt1) and proangiogenic placental growth factor (PlGF) levels in women with PE (n=35) compared to controls with no hypertensive disorders (NHD) (n=43) among subjects with singleton pregnancies that delivered at Hospital Albert Schweitzer (HAS) in Haiti. We divided the preeclamptic women into two groups, early onset (≤ 34 weeks) and late onset (>34 weeks) and examined relationships between sFlt1/PlGF ratios on admission and adverse outcomes (abruption, respiratory complications, stroke, renal insufficiency, eclampsia, maternal death, birth weight <2500 grams, or fetal/neonatal death) in women with PE subgroups as compared to NHD groups separated by week of admission. Data are presented as median (25th-75th centile), n (%), and proportions. Among patients with PE, most (24/35) were admitted at term. Adverse outcome rates in PE were much higher among the early onset group compared to the late onset group (100.0% vs. 54.2%, P=0.007). Plasma angiogenic factors were dramatically altered in both subtypes of PE. Angiogenic factors also correlated with adverse outcomes in both subtypes of PE. The median sFlt1/PlGF ratios for subjects with early onset PE with any adverse outcome vs. NHD <=34 weeks with no adverse outcome were 703.1 (146.6, 1614.9) and 9.6 (3.5, 58.6); P<0.001). Among late onset group the median sFlt1/PlGF ratio for women with any adverse outcome was 130.7 (56.1, 242.6) versus 22.4 (10.2, 58.7; P=0.005) in NHD >34 weeks with no adverse outcome. PE-related adverse outcomes are common in women in Haiti and are associated with profound angiogenic imbalance regardless of gestational age at presentation.

Objectives The utility value attributed to taking pills for prevention can have a major effect on the cost-effectiveness of interventions, but few published studies have systematically quantified this value. We sought to quantify the utility value of taking pills used for prevention of cardiovascular disease (CVD). Design Cross-sectional survey. Setting Central North Carolina. Participants 708 healthcare employees aged 18 years and older. Primary and secondary outcomes Utility values for taking 1 pill/day, assessed using time trade-off, modified standard gamble and willingness-to-pay methods. Results Mean age of respondents was 43 years (19–74). The majority of the respondents were female (83%) and Caucasian (80%). Most (80%) took at least 2 pills/day. Mean utility values for taking 1 pill/day using the time trade-off method were: 0.9972 (95% CI 0.9962 to 0.9980). Values derived from the standard gamble and willingness-to-pay methods were 0.9967 (0.9954 to 0.9979) and 0.9989 (95% CI 0.9986 to 0.9991), respectively. Utility values varied little across characteristics such as age, sex, race, education level or number of pills taken per day. Conclusions The utility value of taking pills daily in order to prevent an adverse CVD health outcome is approximately 0.997. PMID:25967985

Few studies have examined the impact of the built environment (BE) on health behaviours and health outcomes in middle income countries. This study examines associations between self-assessed characteristics of the home and neighbourhood environment and health-related behaviours and health outcomes in an elderly population in Brazil. In a community sample of 6963 community dwellers 60 years old and older living in the state of Rio Grande do Sul, Brazil, associations between self-reported BE conditions and health behaviours and health outcomes were assessed using a structured questionnaire. Multivariate analysis was conducted to investigate these associations while accounting for other relevant characteristics. We found significant positive associations between adverse BE conditions and pulmonary, urinary conditions, gastrointestinal, problems, headache and depression. There were mixed associations between adverse BE conditions and musculoskeletal and sensory conditions, inverse associations with metabolic disorders. and no associations with dermatologic problems and cancer. After accounting for health related behaviours, results suggest a modest association between adverse BE conditions and hypertension, with no significant associations with other indicators of cardiovascular conditions (heart problems, stroke, varicose veins). The findings in this study suggest links between adverse conditions in the BE and health related behaviours in the hypothesized direction. Associations with the health conditions examined here are mixed. We find the strongest evidence for effects of adverse BE conditions for pulmonary and infectious conditions. Significant associations between the adverse BE indicators and health outcomes persist after accounting for health related behaviours, suggesting that BE conditions are linked to health pathways above and beyond the health related behaviours assessed in this study.

Unintended pregnancy is associated with risk behaviors and increased morbidity or mortality for mothers and infants, but a woman's feelings about pregnancy may be more predictive of risk and health outcomes than her intentions. A sample of 1,044 black women who were at increased risk were enrolled at prenatal care clinics in the District of Columbia in 2001-2003. Bivariate and multivariate analyses assessed associations between pregnancy intentions or level of happiness about being pregnant and multiple psychosocial and behavioral risk factors, and identified correlates of happiness to be pregnant. Pregnancy intentions and happiness were strongly associated, but happiness was the better predictor of risk. Unhappy women had higher odds than happy women of smoking, being depressed, experiencing intimate partner violence, drinking and using illicit drugs (odds ratios, 1.7-2.6). The odds of being happy were reduced among women who had other children or a child younger than two, who were single or did not have a current partner, who had had more than one sexual partner in the past year and who reported that the baby's father did not want the pregnancy (0.3-0.6). In contrast, the odds of being happy were elevated among women who had better coping strategies (1.03), who had not used birth control at conception (1.6) and who had 1-2 household members, rather than five or more (2.1). Additional psychosocial screening for happiness about being pregnant and for partner characteristics, particularly the father's desire to have this child, may help improve prenatal care services and prevent adverse health outcomes.

The long tradition of high prevalence of consanguineous marriages in Omani society may have ramifications for reproductive behaviour and health of offspring. To examine the relevance of consanguinity to reproductive behaviour, adverse pregnancy outcome and offspring mortality in Oman. The data analysed came from the 2000 Oman National Health Survey. Selected indicators that are related to reproductive behaviour, adverse pregnancy outcome and offspring mortality were considered as explanatory variables. Various statistical methods and tests were used for data analysis. Consanguineous marriage was found to be associated with lower age at first birth, higher preference for larger family size, lower level of husband-wife communication about use of family planning methods and lower rate of contraceptive use. Although bivariate analysis showed elevated fertility and childhood mortality among the women with consanguineous marriage, after controlling for relevant socio-demographic factors in multivariate analysis, fertility, childhood mortality and foetal loss showed no significant association with consanguinity in Oman. Consanguinity plays an important role in determining some of the aspects of reproduction and health of newborns, but did not show any detrimental effects on fertility and offspring mortality. The high level of consanguinity and its relevance to reproduction in Oman need to be considered in its public health strategy in a culturally acceptable manner.

OBJECTIVE To estimate whether elevations of complement C3a early in pregnancy are predictive of the subsequent development of adverse pregnancy outcomes. METHODS A plasma sample was obtained from each enrolled pregnant woman before 20 weeks of gestation. The cohort (n=1,002) was evaluated for the development of adverse pregnancy outcomes defined as hypertensive diseases of pregnancy (gestational hypertension or preeclampsia), preterm birth (before 37 weeks of gestation), premature rupture of the membranes, pregnancy loss (during the embryonic and fetal period), intrauterine growth restriction, and the composite outcome of any adverse outcome. RESULTS One or more adverse pregnancy outcomes occurred in 211 (21%) of the cohort. The mean levels (ng/mL) of C3a in early pregnancy were significantly (P=<.001) higher among women with one or more adverse outcomes (858±435) compared with women with an uncomplicated pregnancy (741±407). Adjusted for parity and prepregnancy body mass index, women with levels of C3a in the upper quartile in early pregnancy were three times more likely to have an adverse outcome later in pregnancy compared with women in the lowest quartile (95% confidence interval, 1.8–4.8; P<.001). The link between early elevated C3a levels and adverse pregnancy outcomes was driven primarily by individual significant (P<.05) associations of C3a with hypertensive diseases of pregnancy, preterm birth, and premature rupture of the membranes. CONCLUSION Elevated C3a as early as the first trimester of pregnancy is an independent predictive factor for adverse pregnancy outcomes, suggesting that complement-related inflammatory events in pregnancy contribute to the subsequent development of poor outcomes at later stages of pregnancy.

Twenty-nine countries in Africa, Latin America, Asia and the Middle East. Women admitted for delivery in 359 health facilities during 2-4 months between 2010 and 2011. Multilevel logistic regression models were used to estimate the association between young maternal age and adverse pregnancy outcomes. Risk of adverse pregnancy outcomes among adolescent mothers. A total of 124 446 mothers aged ≤24 years and their infants were analysed. Compared with mothers aged 20-24 years, adolescent mothers aged 10-19 years had higher risks of eclampsia, puerperal endometritis, systemic infections, low birthweight, preterm delivery and severe neonatal conditions. The increased risk of intra-hospital early neonatal death among infants born to adolescent mothers was reduced and statistically insignificant after adjustment for gestational age and birthweight, in addition to maternal characteristics, mode of delivery and congenital malformation. The coverage of prophylactic uterotonics, prophylactic antibiotics for caesarean section and antenatal corticosteroids for preterm delivery at 26-34 weeks was significantly lower among adolescent mothers. Adolescent pregnancy was associated with higher risks of adverse pregnancy outcomes. Pregnancy prevention strategies and the improvement of healthcare interventions are crucial to reduce adverse pregnancy outcomes among adolescent women in low- and middle-income countries. © 2014 RCOG The World Health Organization retains copyright and all other rights in the manuscript of this article as submitted for publication.

Waste incineration and adverse birth and neonatal outcomes: a systematic review.

2014-08-01

Public concern about potential health risks associated with incineration has prompted studies to investigate the relationship between incineration and risk of cancer, and more recently, birth outcomes. We conducted a systematic review of epidemiologic studies evaluating the relationship between waste incineration and the risk of adverse birth and neonatal outcomes. Literature searches were performed within the MEDLINE database, through PubMed and Ovid interfaces, for the search terms; incineration, birth, reproduction, neonatal, congenital anomalies and all related terms. Here we discuss and critically evaluate the findings of these studies. A comprehensive literature search yielded fourteen studies, encompassing a range of outcomes (including congenital anomalies, birth weight, twinning, stillbirths, sex ratio and infant death), exposure assessment methods and study designs. For congenital anomalies most studies reported no association with proximity to or emissions from waste incinerators and "all anomalies", but weak associations for neural tube and heart defects and stronger associations with facial clefts and urinary tract defects. There is limited evidence for an association between incineration and twinning and no evidence of an association with birth weight, stillbirths or sex ratio, but this may reflect the sparsity of studies exploring these outcomes. The current evidence-base is inconclusive and often limited by problems of exposure assessment, possible residual confounding, lack of statistical power with variability in study design and outcomes. However, we identified a number of higher quality studies reporting significant positive relationships with broad groups of congenital anomalies, warranting further investigation. Future studies should address the identified limitations in order to help improve our understanding of any potential adverse birth outcomes associated with incineration, particularly focussing on broad groups of anomalies, to inform

Malnutrition is a frequent finding in pediatric health care settings in the form of undernutrition or excess body weight. Its increasing prevalence and impact on overall health status, which is reflected in the adverse outcomes, renders imperative the application of commonly accepted and evidence-based practices and tools by health care providers. Nutrition risk screening on admission and nutrition status evaluation are key points during clinical management of hospitalized pediatric patients, in order to prevent health deterioration that can lead to serious complications and growth consequences. In addition, anthropometric data based on commonly accepted universal growth standards can give accurate results for nutrition status. Both nutrition risk screening and nutrition status assessment are techniques that should be routinely implemented, based on commonly accepted growth standards and methodology, and linked to clinical outcomes. The aim of the present review was to address the issue of hospital malnutrition in pediatric settings in terms of prevalence, outline nutrition status evaluation and nutrition screening process using different criteria and available tools, and present its relationship with outcome measures. Key teaching points • Malnutrition-underweight or excess body weight-is a frequent imbalance in pediatric settings that affects physical growth and results in undesirable clinical outcomes. • Anthropometry interpretation through growth charts and nutrition screening are cornerstones for the assessment of malnutrition.To date no commonly accepted anthropometric criteria or nutrition screening tools are used in hospitalized pediatric patients. • Commonly accepted nutrition status and screening processes based on the World Health Organization's growth standards can contribute to the overall hospital nutrition care of pediatric patients.

The influence of the built environment on adverse birth outcomes.

Adverse birth outcomes are associated with neonatal morbidity and mortality, and higher risk for coronary heart disease, non-insulin-dependent diabetes and hypertension in adulthood. Although there has been considerable research investigating the association between maternal and environmental factors on adverse birth outcomes, one risk factor, not fully understood, is the influence of the built environment. A search of MEDLINE, Scopus, and Cochrane was conducted to find articles assessing the influence of the built environment on preterm birth (PTB), low birth weight (LBW), and small-for-gestational-age (SGA). In total, 41 studies met our inclusion criteria, and were organized into nine categories: Roadways, Greenness, Power Plants, Gas Stations/Wells, Waste Management, Power Lines, Neighborhood Conditions, Food Environment, and Industry. The most common built environmental variable was roads/traffic, encompassing 17/41 (41%) of the articles reviewed, of which 12/17 (71%) found a significant small to moderate association between high traffic exposure and adverse birth outcomes.

Objective To review all admissions (age > 13) to three surgical patient care centers at a single academic medical center between January 1, 1995, and December 6, 1999, for significant surgical adverse events. Summary Background Data Little data exist on the interrelationships between surgical adverse events, risk management, malpractice claims, and resulting indemnity payments to plaintiffs. The authors hypothesized that examination of this process would identify performance improvement opportunities overlooked by standard medical peer review; the risk of litigation would be constant across the three homogeneous patient care centers; and the risk management process would exceed the performance improvement process. Methods Data collected included patient demographics (age, gender, and employment status), hospital financials (hospital charges, costs, and financial class), and outcome. Outcome categories were medical (disability: <1 month, 1–6 months, permanent/death), legal (no legal action, settlement, summary judgment), financial (indemnity payments, legal fees, write-offs), and cause and effect analysis. Cause and effect analysis attempts to identify system failures contributing to adverse outcomes. This was determined by two independent analysts using the 17 Harvard criteria and subdividing these into subsystem causative factors. Results The study group consisted of 130 patients with surgical adverse events resulting in total liabilities of $8.2 million. The incidence of adverse events per 1,000 admissions across the three patient care centers was similar, but indemnity payments per 1,000 admissions varied (cardiothoracic = $30, women’s health = $90, trauma = $520). Patient demographics were not predictive of high-risk subgroups for adverse events or litigation. In terms of medical outcome, 51 patients had permanent disability or death, accounting for 98% of the indemnity payments. In terms of legal outcome, 103 patients received no indemnity payments, 15

Background Adverse childhood experiences (ACEs; e.g., abuse, neglect, parental loss, etc.) have been associated with increased risk for later-life disease and dysfunction using adults’ retrospective self-reports of ACEs. Research should test whether associations between ACEs and health outcomes are the same for prospective and retrospective ACE measures. Methods We estimated agreement between ACEs prospectively-recorded throughout childhood (by Study staff at Study member ages 3, 5, 7, 9, 11, 13, and 15) and retrospectively-recalled in adulthood (by Study members when they reached age 38), in the population-representative Dunedin cohort (N=1,037). We related both retrospective and prospective ACE measures to physical, mental, cognitive, and social health at midlife measured through both objective (e.g., biomarkers and neuropsychological tests) and subjective (e.g., self-reported) means. Results Dunedin and CDC ACE distributions were similar. Retrospective and prospective measures of adversity showed moderate agreement (r=.47, p<.001; weighted Kappa = .31, 95% CI: .27–.35). Both associated with all midlife outcomes. As compared to prospective ACEs, retrospective ACEs showed stronger associations with life outcomes that were subjectively assessed, and weaker associations with life outcomes that were objectively assessed. Recalled ACEs and poor subjective outcomes were correlated regardless of whether prospectively-recorded ACEs were evident. Individuals who recalled more ACEs than had been prospectively recorded were more neurotic than average, and individuals who recalled fewer ACEs than recorded were more agreeable. Conclusions Prospective ACE records confirm associations between childhood adversity and negative life outcomes found previously using retrospective ACE reports. However, more agreeable and neurotic dispositions may respectively bias retrospective ACE measures toward underestimating the impact of adversity on objectively-measured life outcomes and

Anemia is a leading cause of maternal deaths and adverse pregnancy outcomes in developing countries. We conducted a systematic review and meta-analysis to estimate the pooled prevalence of anemia, the association between maternal anemia and pregnancy outcomes, and the population-attributable fraction (PAF) of these outcomes that are due to anemia in low- and middle-income countries. PubMed, EMBASE, CINAHL, and the British Nursing Index were searched from inception to May 2015 to identify cohort studies of the association between maternal anemia and pregnancy outcomes. The anemic group was defined as having hemoglobin concentrations <10 or <11 g/dL or hematocrit values <33% or <34% depending on the study. A metaregression and stratified analysis were performed to assess the effects of study and participant characteristics on adverse pregnancy risk. The pooled prevalence of anemia in pregnant women by region and country-income category was calculated with the use of a random-effects meta-analysis. Of 8182 articles reviewed, 29 studies were included in the systematic review, and 26 studies were included in the meta-analysis. Overall, 42.7% (95% CI: 37.0%, 48.4%) of women experienced anemia during pregnancy in low- and middle-income countries. There were significantly higher risks of low birth weight (RR: 1.31; 95% CI: 1.13, 1.51), preterm birth (RR: 1.63; 95% CI: 1.33, 2.01), perinatal mortality (RR: 1.51; 95% CI: 1.30, 1.76), and neonatal mortality (RR: 2.72; 95% CI: 1.19, 6.25) in pregnant women with anemia. South Asian, African, and low-income countries had a higher pooled anemia prevalence than did other Asian and upper-middle-income countries. Overall, in low- and middle-income countries, 12% of low birth weight, 19% of preterm births, and 18% of perinatal mortality were attributable to maternal anemia. The proportion of adverse pregnancy outcomes attributable to anemia was higher in low-income countries and in the South Asian region. Maternal anemia remains a

Lack of trace elements during pregnancy is detrimental to maternal and fetal health. Our aim is to study the changes in trace element levels in Chinese pregnant women and their association with adverse pregnancy outcomes. 1568 cases of Chinese pregnant women in remote areas were collected for a prospective cohort study. Serum copper, zinc, calcium and iron levels were measured at pre-pregnancy, 1st trimester (7w-12w), 2nd trimester (24w-28w) and 3rd trimester (35w-40w). (1) Serum copper levels was significantly higher after pregnancy than before, calcium and iron levels decreased, but zinc levels did not change significantly. (2) Copper and zinc deficiency in pregnant women was not a common finding, but lack of iron and calcium was frequently encountered; iron deficiency was especially common in the 3rd trimester (42.27%). (3) Serum zinc and iron levels in patients who either had a miscarriage or a preterm delivery were significantly lower than in the control group (p < 0.05). In patients with premature rupture of membranes, serum zinc levels were significantly lower (p < 0.05). In patients with intrauterine growth restriction (IUGR), serum copper, zinc, calcium and iron were significantly lower (p < 0.05). Trace elements is closely associated with fetal growth and development during pregnancy. Deficiency can lead to adverse pregnancy outcomes. Therefore, we should have a reasonable diet, replenish trace elements, therefore reducing the occurrence of adverse pregnancy outcomes.

Identifying exposure disparities in air pollution epidemiology specific to adverse birth outcomes

NASA Astrophysics Data System (ADS)

Geer, Laura A.

2014-10-01

More than 147 million people in the US live in areas where pollutant levels are above regulatory limits and pose a risk to health. Most of the vast network of air pollutant monitors in the US are located in places with higher pollution levels and a higher density of pollutant sources (e.g., point sources from industrial pollution). Vulnerable populations are more likely to live closer to pollutant sources, and thus closer to pollutant monitors. These differential exposures have an impact on maternal and child health; maternal air pollutant exposures have been linked to adverse outcomes such as preterm birth and infant low birth weight. Several studies are highlighted that address methodological approaches in the study of air pollution and health disparities.

Adverse Childhood Experiences and Health in Adulthood in a Rural Population-Based Sample

Background Adverse childhood experiences (ACEs), including emotional abuse, substance abuse in the household, separation or divorce, physical abuse, violence between adults, mental illness in the household, sexual abuse, or incarceration of a household member, have the potential to profoundly impact health and well-being in adulthood. To assess whether previously reported relationships between ACEs and health outcomes withstand validation, we conducted a community-based ACE study with the unique capacity to link self-reported ACEs and other survey results to validated health data in an electronic medical record (EMR). Methods Information regarding ACEs and health outcomes was captured from 2013–2014 via a telephone survey of residents of the predominantly rural northern and central regions of Wisconsin and electronic abstraction of EMR data. ACE score was calculated by counting each exposure as one point. We examined the relationship between ACE score, type, and self-reported and validated health outcomes. Results A total of 800 participants completed the telephone survey. Overall, 62% reported at least one ACE and 15% reported experiencing four or more. All self-reported measures of poor health were associated with increased ACE score. EMR data were positively correlated with ACE score for increased body mass index and diagnoses of depression, anxiety, and asthma. In contrast, diagnoses of hypertension, hypercholesterolemia, myocardial infarction, and skin and other cancers were inversely related to ACE score. Emotional abuse was the most common ACE reported followed by substance abuse in the household. ACEs tended to cluster so that people who reported at least one ACE were likely to have experienced multiple ACEs. There was no clear correlation between abuse type (e.g., direct abuse vs. household dysfunction) and health outcomes. Conclusions In the first community-based study to link self-reported ACEs to comprehensive health measures documented in the medical

Older adults are often transferred from hospitals to skilled nursing facilities (SNFs) for post-acute care. Patients may be at risk for adverse outcomes after SNF discharges, but little research has focused on this period. Assessment of the feasibility of a transitional care intervention based on a combination of manual information transmission and health information technology to provide automated alert messages to primary care physicians and staff; pre-post analysis to assess potential impact. A multispecialty group practice. Adults aged 65 and older, discharged from SNFs to home; comparison group drawn from SNF discharges during the previous 1.5 years, matched on facility, patient age, and sex. For the pre-post analysis, we tracked rehospitalization within 30 days after discharge and adverse drug events within 45 days. The intervention was developed and implemented with manual transmission of information between 8 SNFs and the group practice followed by entry into the electronic health record. The process required a 5-day delay during which a large portion of the adverse events occurred. Over a 1-year period, automated alert messages were delivered to physicians and staff for the 313 eligible patients discharged from the 8 SNFs to home. We compared outcomes to those of individually matched discharges from the previous 1.5 years and found similar percentages with 30-day rehospitalizations (31% vs 30%, adjusted HR 1.06, 95% CI 0.80-1.4). Within the adverse drug event (ADE) study, 30% of the discharges during the intervention period and 30% of matched discharges had ADEs within 45 days. Older adults discharged from SNFs are at high risk of adverse outcomes immediately following discharge. Simply providing alerts to outpatient physicians, especially if delivered multiple days after discharge, is unlikely to have any impact on reducing these rates.

Adverse Outcome Pathways – Organizing Toxicological ...

EPA Pesticide Factsheets

The number of chemicals for which environmental regulatory decisions are required far exceeds the current capacity for toxicity testing. High throughput screening (HTS) commonly used for drug discovery has the potential to increase this capacity. The adverse outcome pathway (AOP) concept has emerged as a natural framework for connecting high throughput toxicity testing (HTT) results to potential impacts on humans and wildlife populations. An AOP consists of two main components that describe the biological mechanisms driving toxicity. Key events represent biological processes essential for causing the adverse outcome that are also measurable experimentally. Key event relationships capture the biological processes connecting the key events. Evidence documented for each KER based on measurements of the KEs can provide the confidence needed for extrapolating HTT from early key events to overt toxicity represented by later key events based on the AOP. The IPCS mode of action (MOA) framework incorporates information required for making a chemical-specific toxicity determination. Given the close relationship between the AOP and MOA frameworks, it is possible to assemble an MOA by incorporating HTT results, chemical properties including absorption, distribution, metabolism, and excretion (ADME), and an AOP describing the biological basis of toxicity thereby streamlining the process. While current applications focus on the assessment of risk for environmental chemicals,

To assess factors associated with timing of hepatoportoenterostomy (HPE) and adverse perioperative outcomes in patients with biliary atresia in the US. We examined hospitalizations in infants aged <1 year using the National Inpatient Sample database for 2000-2011. We identified cases using the International Classification of Diseases, Ninth Revision, Clinical Modification codes for biliary atresia and HPE. Multivariable logistic regression models were used to examine association between select factors and age at HPE, as well as adverse perioperative outcomes. Our analysis of 1243 biliary atresia hospitalizations showed that only 37.7% of patients had HPE in the first 60 days of life. Patients who underwent HPE after 60 days of age were uninsured, were more likely to be black (aOR, 4.22; 95% CI, 1.49-11.95), less likely to be admitted at a teaching hospital (aOR, 0.27; 95% CI 0.10-0.79), and less likely to have a concomitant congenital malformation (aOR, 0.49; 95% CI 0.25-0.98). Patients with delayed age at HPE incurred significantly higher hospital costs ($57 914 vs $34 074; P = .026). Delayed age at HPE and weekend admission were independently associated with increased odds of adverse perioperative outcome (aOR, 1.09; 95% CI, 1.01-3.02 and 3.98; 95% CI, 1.67-9.46, respectively). Current outcomes in patients with biliary atresia in the United States are suboptimal and result in higher costs. The specific factors associated with delayed care are further evidence that universal health care and screening are needed for all infants, along with systematic referral of potential patients with biliary atresia to specialized health centers.

Conceptual model for assessing criteria air pollutants in a multipollutant context: A modified adverse outcome pathway approach.

PubMed

Buckley, Barbara; Farraj, Aimen

2015-09-01

Air pollution consists of a complex mixture of particulate and gaseous components. Individual criteria and other hazardous air pollutants have been linked to adverse respiratory and cardiovascular health outcomes. However, assessing risk of air pollutant mixtures is difficult since components are present in different combinations and concentrations in ambient air. Recent mechanistic studies have limited utility because of the inability to link measured changes to adverse outcomes that are relevant to risk assessment. New approaches are needed to address this challenge. The purpose of this manuscript is to describe a conceptual model, based on the adverse outcome pathway approach, which connects initiating events at the cellular and molecular level to population-wide impacts. This may facilitate hazard assessment of air pollution mixtures. In the case reports presented here, airway hyperresponsiveness and endothelial dysfunction are measurable endpoints that serve to integrate the effects of individual criteria air pollutants found in inhaled mixtures. This approach incorporates information from experimental and observational studies into a sequential series of higher order effects. The proposed model has the potential to facilitate multipollutant risk assessment by providing a framework that can be used to converge the effects of air pollutants in light of common underlying mechanisms. This approach may provide a ready-to-use tool to facilitate evaluation of health effects resulting from exposure to air pollution mixtures. Published by Elsevier Ireland Ltd.

The aim of this study is to evaluate the efficacy of an ultrasonographic measurement of placental thickness and the correlation of a thick placenta with adverse perinatal outcome. Placental thickness was measured in single gravidas, 16 to 40 weeks of gestation, between 2005 and 2009. Placentas were considered to be thick if their measured thickness were above the 95th percentile for gestational age. The incidence of thick placentas was 4.3% (138/3,183). Perinatal morbidity and neonatal conditions were worse in cases with thick placenta rather than without thick placenta. Ultrasonographic measurement of placental thickness is a simple method to estimate placental size. Thick placenta may be a useful predictor of adverse pregnancy outcomes.

Periodontal disease has been linked with a number of conditions, such as cardiovascular disease, stroke, diabetes and adverse pregnancy outcomes, all likely through systemic inflammatory pathways. It is common in women of reproductive age and gum conditions tend to worsen during pregnancy. Some evidence from observational studies suggests that periodontal intervention may reduce adverse pregnancy outcomes. There is need for a comprehensive Cochrane review of randomised trials to assess the effect of periodontal treatment on perinatal and maternal health. To assess the effects of treating periodontal disease in pregnant women in order to prevent or reduce perinatal and maternal morbidity and mortality. Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 6 October 2016), Cochrane Pregnancy and Childbirth's Trials Register (to 7 October 2016), the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 9) in the Cochrane Library, MEDLINE Ovid (1946 to 6 October 2016), Embase Ovid (1980 to 6 October 2016), and LILACS BIREME Virtual Health Library (Latin American and Caribbean Health Science Information database; 1982 to 6 October 2016). ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials on 6 October 2016. We placed no restrictions on the language or date of publication when searching the electronic databases. We included all randomised controlled trials (RCTs) investigating the effects of periodontal treatment in preventing or reducing perinatal and maternal morbidity and mortality. We excluded studies where obstetric outcomes were not reported. Two review authors independently screened titles and abstracts and extracted data using a prepiloted data extraction form. Missing data were obtained by contacting authors and risk of bias was assessed using Cochrane's 'Risk of bias' tool. Where appropriate

Anaemia during pregnancy is an important public health problem. We investigated whether the association between maternal anaemia during pregnancy and adverse perinatal outcomes differed between nulliparous and multiparous women. A retrospective population-based cohort study was conducted using data on all singleton births (n = 290 662) recorded in the Finnish Medical Birth Register during 2006-10. Maternal anaemia was defined as a maternal haemoglobin level of <100 g/L). Adverse perinatal outcomes that were examined included preterm delivery (<37 weeks), small-for-gestational age (SGA, <2 standard deviation), admission to neonatal intensive care, stillbirth, early neonatal death, and major congenital anomalies. An association between anaemia and adverse outcomes was assessed by logistic regression analysis. The prevalence of anaemia during pregnancy was 2.5% among nulliparous women and 2.3% among multiparous women. Among nulliparous women, anaemia was not associated with adverse perinatal outcomes. Among multiparous women, anaemia was associated with preterm delivery (adjusted odds ratio [aOR] 1.32, [95% CI 1.14, 1.53]), SGA (aOR 1.27, [95% CI 1.04, 1.55]), and admission to neonatal intensive care (aOR 1.23, [95% CI 1.10, 1.38]); there was a trend towards increased odds of major congenital anomalies (aOR 1.15, [95% CI 0.99, 1.34]). These data underscore that maternal anaemia is associated with several adverse perinatal outcomes. This association was, however, confined to multiparous women. Future research should explore in detail the timing of anaemia in these associations. © 2014 John Wiley & Sons Ltd.

Many patients discontinue statin treatment, often after having a possible adverse reaction. The risks and benefits of continued statin therapy after an adverse reaction are not known. To examine the relationship between continuation of statin therapy (any prescription within 12 months after an adverse reaction) and clinical outcomes. Retrospective cohort study. Primary care practices affiliated with 2 academic medical centers. Patients with a presumed adverse reaction to a statin between 2000 and 2011. Information on adverse reactions to statins was obtained from structured electronic medical record data or natural-language processing of narrative provider notes. The primary composite outcome was time to a cardiovascular event (myocardial infarction or stroke) or death. Most (81%) of the adverse reactions to statins were identified from the text of electronic provider notes. Among 28 266 study patients, 19 989 (70.7%) continued receiving statin prescriptions after the adverse reaction. Four years after the presumed adverse event, the cumulative incidence of the composite primary outcome was 12.2% for patients with continued statin prescriptions, compared with 13.9% for those without them (difference, 1.7% [95% CI, 0.8% to 2.7%]; P < 0.001). In a secondary analysis of 7604 patients for whom a different statin was prescribed after the adverse reaction, 2014 (26.5%) had a documented adverse reaction to the second statin, but 1696 (84.2%) of those patients continued receiving statin prescriptions. The risk for recurrent adverse reactions to statins could not be established for the entire sample. It was also not possible to determine whether patients actually took the statins. Continued statin prescriptions after an adverse reaction were associated with a lower incidence of death and cardiovascular events.

A short interpregnancy interval (IPI) following a delivery is believed to be associated with adverse outcomes in the next pregnancy. The optimum IPI following miscarriage is controversial. Based on a single large-scale study in Latin and South America, the World Health Organization recommends delaying pregnancy for 6 months after a miscarriage to achieve optimal outcomes in the next pregnancy. Our aim was to determine if a short IPI (<6 months) following miscarriage is associated with adverse outcomes in the next pregnancy. Studies were retrieved from MEDLINE, Embase and Pubmed, with no time and language restrictions. The search strategy used a combination of Medical Subject Headings terms for miscarriage, IPI and adverse outcomes. Bibliographies of the retrieved articles were also searched by hand. All studies including women with at least one miscarriage, comparing subsequent adverse pregnancy outcomes for IPIs of less than and more than 6 months were included. Two independent reviewers screened titles and abstracts for inclusion. Characteristics of the studies were extracted and quality assessed using Critical Appraisal Skills Programme criteria. A systematic review and meta-analysis were conducted to compare short (<6 months) versus long (>6 months) IPI following miscarriage in terms of risk of further miscarriage, preterm birth, stillbirth, pre-eclampsia and low birthweight babies in the subsequent pregnancy. Review Manager 5.3 was used for conducting meta-analyses. Sixteen studies including 1 043 840 women were included in the systematic review and data from 10 of these were included in one or more meta-analyses (977 972 women). With an IPI of less than 6 months, the overall risk of further miscarriage (Risk ratio (RR) 0.82 95% CI 0.78, 0.86) and preterm delivery (RR 0.79 95% CI 0.75, 0.83) were significantly reduced. The pooled risks of stillbirth (RR 0.88 95% CI 0.76, 1.02); low birthweight (RR 1.05 95% CI 0.48, 2.29) and pre-eclampsia (RR 0.95 95% CI 0

Cardiovascular disease and type 2 diabetes are examples of chronic diseases that impose significant morbidity and mortality in the general population worldwide. Most chronic diseases are associated with underlying preventable risk factors, such as elevated blood pressure, high blood glucose or glucose intolerance, high lipid levels, physical inactivity, excessive sedentary behaviours, and overweight/obesity. The occurrence of intermediate outcomes during childhood increases the risk of disease in adulthood. Sugar-sweetened beverages are known to be significant sources of additional caloric intake, and given recent attention to their contribution in the development of chronic diseases, a systematic review is warranted. We will assess whether the consumption of sugar-sweetened beverages in children is associated with adverse health outcomes and what the potential moderating factors are. Of interest are studies addressing sugar-sweetened beverage consumption, taking a broad perspective. Both direct consumption studies as well as those evaluating interventions that influence consumption (e.g. school policy, educational) will be relevant. Non-specific or multi-faceted behavioural, educational, or policy interventions may also be included subject to the level of evidence that exists for the other interventions/exposures. Comparisons of interest and endpoints of interest are pre-specified. We will include randomized controlled trials, controlled clinical trials, interrupted time series studies, controlled before-after studies, prospective and retrospective comparative cohort studies, case-control studies, and nested case-control designs. The MEDLINE®, Embase, The Cochrane Library, CINAHL, ERIC, and PsycINFO® databases and grey literature sources will be searched. The processes for selecting studies, abstracting data, and resolving conflicts are described. We will assess risk of bias using design-specific tools. To determine sets of confounding variables that should be

In this study, we evaluated the association between prenatal depression symptoms adverse birth outcomes in African-American women. We conducted a retrospective cohort study of 261 pregnant African-American women who were screened with the Edinburgh Postnatal Depression Scale (EPDS) at their initial prenatal visit. Medical records were reviewed to assess pregnancy and neonatal outcomes, specifically preeclampsia, preterm birth, intrauterine growth retardation, and low birth weight. Using multivariable logistic regression models, an EPDS score ≥10 was associated with increased risk for preeclampsia, preterm birth, and low birth weight. An EPDS score ≥10 was associated with increased risk for intrauterine growth retardation, but after controlling for behavioral risk factors, this association was no longer significant. Patients who screen positive for depression symptoms during pregnancy are at increased risk for multiple adverse birth outcomes. In a positive, patient-rated depression screening at the initial obstetrics visit, depression is associated with increased risk for multiple adverse birth outcomes. Given the retrospective study design and small sample size, these findings should be confirmed in a prospective cohort study.

The aim of this paper was to systematically review the evidence for the association between television viewing and diet in children ages 2-6. Data sources included PubMed, PsycINFO, EMBASE, ERIC, SportDISCUS, Sociological Abstracts, Web of Science and hand searches of reference lists of relevant articles. Twelve studies were reviewed in which the relationship between television viewing and diet was assessed in children between the ages of 2 and 6. All but one study reported significant relationship between television viewing time and adverse dietary outcomes. Parent-reported television viewing time was used to assay child television viewing in all included studies. Food frequency survey was the most frequent method of dietary assessment, and parent served as proxies for children in all studies. Lower fruit and/or vegetable intake was the most frequently reported dietary outcome, followed by increased energy intake with increased television viewing. The majority of studies reported adverse dietary outcomes with as little as 1 h of daily television exposure. While these results are consistent with recommendations from child health advocates to limit television viewing in young children, they also suggest that further efforts to limit television viewing in young children may be needed to aid in obesity prevention. © 2012 The Authors. obesity reviews © 2012 International Association for the Study of Obesity.

The maternal microbiome is recognized as a key determinant of a range of important maternal and child health outcomes, and together with perinatal factors influences the infant microbiome. This manuscript provides a summary review of research investigating: (1) the role of the maternal microbiome in pregnancy outcomes known to adversely influence neonatal and infant health, including preterm birth, cardiometabolic complications of pregnancy such as preeclampsia and gestational diabetes, and excessive gestational weight gain; (2) factors with an established link to adverse pregnancy outcomes that are known to influence the composition of the maternal microbiome; and (3) strategies for promoting a healthy maternal microbiome, recognizing that much more research is needed in this area.

Studies investigating associations between ambient air pollution and fetal growth and gestational duration have reported inconclusive findings. The study goal was to use the Environmental Public Health Tracking Network to describe the association between exposure to particulate matter (PM2.5) and ozone and term low birth weight (TLBW) in New York State. Birth data for the years 2001-2006 were linked to Census data and hierarchical Bayesian modeled air pollution data. Daily 8-hour maximums for ozone and daily average PM2.5 estimates were averaged by trimester and exposure quartiles. The Environmental Public Health Tracking Academic Center for Excellence at Rutgers University partnered with New York and several other states to create a statistical program that uses logistic regression to determine the association between air pollution exposure and TLBW. There were no consistent dose-response relationships between the pollutants and TLBW. Ozone exposure was associated with a higher risk of TLBW only in the first trimester, but these results were not statistically significant. Exposure to the third quartile of ozone for the full gestational period had negative associations with TLBW (odds ratio = 0.86; 95% confidence interval, 0.81-0.92). Collaboration within the Environmental Public Health Tracking Network to share methods and data for research proved feasible and efficient in assessing the relationship of air pollutants to adverse birth outcomes. This study finds little evidence to support positive associations between exposure to ozone or PM2.5 and TLBW in New York State.

Assessing the interrelatedness of multiple types of adverse childhood experiences and odds for poor health in South Carolina adults.

Adverse childhood experiences (ACEs) have been linked to negative health outcomes in adulthood, but little research has been done on the effect of ACEs on the health and well-being of adults in South Carolina (SC). This study analyzed a sample of 9744 respondents who participated in the 2014 South Carolina Behavioral Risk Factor Surveillance System (BRFSS) to examine the relationship among childhood experiences of physical, sexual, and emotional abuse, as well as witnessing household violence, on mental and physical health outcomes in adulthood among SC residents. Twenty-two percent of survey respondents reported poor general health (22.1%), and a smaller proportion reported high frequent mental distress in the past month (13.1%). Each category of childhood experiences was associated with an increase in the risk of poor general health. Individuals reporting three or more types of experiences were more likely to report poor health (aOR 2.89; 95% CI 2.86-2.92) than adults without such experiences. Respondents reporting three or more types of childhood adverse experiences were more likely to report frequent mental distress (aOR 3.29; 95% CI 3.26-3.33) compared to adults who did not report three or more types of adversity. Findings from the SC BRFSS highlight a connection between ACEs and negative health outcomes later in life. Given that results of this study also demonstrated that increased exposure to ACEs was associated with greater odds of negative health in adulthood, preventing adverse events such as experiencing abuse or witnessing domestic violence in childhood will have significant effects on later adult health.

Correlates of adverse childhood events among adults with schizophrenia spectrum disorders.

PubMed

Rosenberg, Stanley D; Lu, Weili; Mueser, Kim T; Jankowski, Mary Kay; Cournos, Francine

2007-02-01

Multiple studies have found that childhood adversity is related to a range of poor mental health, substance abuse, poor physical health, and poor social functioning outcomes in the general population of adults. However, despite the high rates of childhood adversity in schizophrenia, the clinical correlates of these events have not been systematically evaluated. This study evaluated the relationship between adverse experiences in childhood and functional, clinical, and health outcomes among adults with schizophrenia. The authors surveyed 569 adults with schizophrenia regarding adverse childhood events (including physical abuse, sexual abuse, parental mental illnesses, loss of a parent, parental separation or divorce, witnessing domestic violence, and foster or kinship care). The relationships between cumulative exposure to these events and psychiatric, physical, and functional outcomes were evaluated. Increased exposure to adverse childhood events was strongly related to psychiatric problems (suicidal thinking, hospitalizations, distress, and posttraumatic stress disorder), substance abuse, physical health problems (HIV infection), medical service utilization (physician visits), and poor social functioning (homelessness or criminal justice involvement). The findings extend the results of research in the general population by suggesting that childhood adversity contributes to worse mental health, substance abuse, worse physical health, and poor functional outcomes in schizophrenia.

Risk of Adverse Health Outcomes and Decrements in Performance Due to In-flight Medical Conditions

NASA Technical Reports Server (NTRS)

2017-01-01

The drive to undertake long-duration space exploration missions at greater distances from Earth gives rise to many challenges concerning human performance under extreme conditions. At NASA, the Human Research Program (HRP) has been established to investigate the specific risks to astronaut health and performance presented by space exploration, in addition to developing necessary countermeasures and technology to reduce risk and facilitate safer, more productive missions in space (NASA Human Research Program 2009). The HRP is divided into five subsections, covering behavioral health, space radiation, habitability, and other areas of interest. Within this structure is the ExMC Element, whose research contributes to the overall development of new technologies to overcome the challenges of expanding human exploration and habitation of space. The risk statement provided by the HRP to the ExMC Element states: "Given that medical conditions/events will occur during human spaceflight missions, there is a possibility of adverse health outcomes and decrements in performance in mission and for long term health" (NASA Human Research Program 2016). Within this risk context, the Exploration Medical Capabilities (ExMC) Element is specifically concerned with establishing evidenced-based methods of monitoring and maintaining astronaut health. Essential to completing this task is the advancement in techniques that identify, prevent, and treat any health threats that may occur during space missions. The ultimate goal of the ExMC Element is to develop and demonstrate a pathway for medical system integration into vehicle and mission design to mitigate the risk of medical issues. Integral to this effort is inclusion of an evidence-based medical and data handling system appropriate for long-duration, exploration-class missions. This requires a clear Concept of Operations, quantitative risk metrics or other tools to address changing risk throughout a mission, and system scoping and system

Exposure to childhood adversity may explain why only a minority of combatants exposed to trauma develop psychological problems. To examine the association between self-reported childhood vulnerability and later health outcomes in a large randomly selected male military cohort. Data are derived from the first stage of a cohort study comparing Iraq veterans and non-deployed UK military personnel. We describe data collected by questionnaire from males in the regular UK armed forces (n=7937). Pre-enlistment vulnerability is associated with being single, of lower rank, having low educational attainment and serving in the Army. Pre-enlistment vulnerability is associated with a variety of negative health outcomes. Two main factors emerge as important predictors of ill health: a 'family relationships' factor reflecting the home environment and an 'externalising behaviour' factor reflecting behavioural disturbance. Pre-enlistment vulnerability is an important individual risk factor for ill health in military men. Awareness of such factors is important in understanding post-combat psychiatric disorder.

Clinical outcomes and adverse effect monitoring in allergic rhinitis.

The subjective recording in diary cards of symptoms of itch, sneeze, nose running, and blockage, with the use of a rating scale to indicate the level of severity, is usual for clinical trials in allergic rhinitis. The primary outcome measure is usually a composite score that enables a single total symptoms score endpoint. It is appreciated, however, that rhinitis has a greater effect on the individual than is reflected purely by the recording of anterior nasal symptoms. Nasal obstruction is troublesome and may lead to sleep disturbance in addition to impaired daytime concentration and daytime sleepiness. These impairments affect school and work performance. Individuals with rhinitis find it socially embarrassing to be seen sneezing, sniffing, or blowing their nose. To capture these and other aspects of the disease-specific health-related quality of life, questionnaires such as the Rhinoconjunctivitis Quality of Life Questionnaire have been developed and validated for clinical trial use. The adoption of health-related quality of life questionnaires into clinical trials broadens the information obtained regarding the effect of the therapeutic intervention and helps focus on issues relevant to the individual patient. It must be appreciated that it is not only the disease that may adversely affect health-related quality of life; administered therapy, although intended to be beneficial, may also cause health impairment. Adverse-event monitoring is thus essential in clinical trials. The first-generation H 1 -histamines, because of their effect on central H 1 -receptors, are classically associated with central nervous system (CNS) effects such as sedation. Although this is not always perceived by the patient, it is clearly evident with objective performance testing, and positron emission tomography scanning has directly demonstrated the central H 1 -receptor occupancy. The second-generation H 1 -antihistamines have reduced central H 1 -receptor occupancy and considerably

Neighborhood adversity, child health, and the role for community development.

Jutte, Douglas P; Miller, Jennifer L; Erickson, David J

2015-03-01

Despite medical advances, childhood health and well-being have not been broadly achieved due to rising chronic diseases and conditions related to child poverty. Family and neighborhood living conditions can have lasting consequences for health, with community adversity affecting health outcomes in significant part through stress response and increased allostatic load. Exposure to this "toxic stress" influences gene expression and brain development with direct and indirect negative consequences for health. Ensuring healthy child development requires improving conditions in distressed, high-poverty neighborhoods by reducing children's exposure to neighborhood stressors and supporting good family and caregiver functioning. The community development industry invests more than $200 billion annually in low-income neighborhoods, with the goal of improving living conditions for residents. The most impactful investments have transformed neighborhoods by integrating across sectors to address both the built environment and the social and service environment. By addressing many facets of the social determinants of health at once, these efforts suggest substantial results for children, but health outcomes generally have not been considered or evaluated. Increased partnership between the health sector and community development can bring health outcomes explicitly into focus for community development investments, help optimize intervention strategies for health, and provide natural experiments to build the evidence base for holistic interventions for disadvantaged children. The problems and potential solutions are beyond the scope of practicing pediatricians, but the community development sector stands ready to engage in shared efforts to improve the health and development of our most at-risk children.

This study examined whether self-focused and other-focused resiliency help explain how early family adversity relates to perceived stress, subjective health, and health behaviors in college women. Female students (N = 795) participated between October 2009 and May 2010. Participants completed self-report measures of early family adversity, self-focused (self-esteem, personal growth initiative) and other-focused (perceived social support, gratitude) resiliency, stress, subjective health, and health behaviors. Using structural equation modeling, self-focused resiliency associated with less stress, better subjective health, more sleep, less smoking, and less weekend alcohol consumption. Other-focused resiliency associated with more exercise, greater stress, and more weekend alcohol consumption. Early family adversity was indirectly related to all health outcomes, except smoking, via self-focused and other-focused resiliency. Self-focused and other-focused resiliency represent plausible mechanisms through which early family adversity relates to stress and health in college women. This highlights areas for future research in disease prevention and management.

To evaluate the association between pregnancy loss history and adverse pregnancy outcomes. Pregnancy history was captured during a computer-assisted personal interview for 21,277 women surveyed in the National Survey of Family Growth (1995-2013). History of pregnancy loss (<20 weeks) at first parity was categorized in three ways: number of losses, maximum gestational age of loss(es), and recency of last pregnancy loss. We estimated risk ratios for a composite measure of selected adverse pregnancy outcomes (preterm, stillbirth, or low birthweight) at first parity and in any future pregnancy, separately, using predicted margins from adjusted logistic regression models. At first parity, compared with having no loss, having 3+ previous pregnancy losses (adjusted risk ratio (aRR) = 1.66 [95% CI = 1.13, 2.43]), a maximum gestational age of loss(es) at ≥10 weeks (aRR = 1.28 [1.04, 1.56]) or having experienced a loss 24+ months ago (aRR = 1.36 [1.10, 1.68]) were associated with increased risks of adverse pregnancy outcomes. For future pregnancies, only having a history of 3+ previous pregnancy losses at first parity was associated with increased risks (aRR = 1.97 [1.08, 3.60]). Number, gestational age, and recency of pregnancy loss at first parity were associated with adverse pregnancy outcomes in U.S. women. Published by Elsevier Inc.

Immigration from Ethiopia to Israel started about 30 years ago. We aimed to compare birth outcomes between Israeli women of Ethiopian origin and Israeli-born, non-Ethiopian women. We hypothesized a higher frequency of adverse birth outcomes among Ethiopian women and a trend of improvement among those who were raised in Israel since early childhood. This is a descriptive study, comparing birth outcomes of Ethiopian (n = 1,319) and non-Ethiopian women (n = 27,307) who gave birth in a medical center in Central Israel in 2002 to 2009. Ethiopian women were further categorized by age at immigration. Logistic regressions were constructed to compare the incidence of adverse birth outcomes between Ethiopian and non-Ethiopian women, controlling for potential confounders. Ethiopian women had about twice the incidence of very and extremely preterm births, compared with non-Ethiopians. Ethiopian women had twice the odds for neonates who were either small for gestational age or had low 5-minute Apgar scores. Ethiopian women had about threefold increased risk of stillbirths (OR 2.9 [95% CI 1.87-4.49]). No trend of improvement was noted for women who were raised in Israel from early childhood. Ethiopian women are at increased risk of adverse birth outcomes. Future research is needed to investigate the underlying causes for the increased risks and lack of improvement among those who were raised in Israel that will lead to effective interventions. © 2015 Wiley Periodicals, Inc.

Quantitative Adverse Outcome Pathways and Their ...

EPA Pesticide Factsheets

A quantitative adverse outcome pathway (qAOP) consists of one or more biologically based, computational models describing key event relationships linking a molecular initiating event (MIE) to an adverse outcome. A qAOP provides quantitative, dose–response, and time-course predictions that can support regulatory decision-making. Herein we describe several facets of qAOPs, including (a) motivation for development, (b) technical considerations, (c) evaluation of confidence, and (d) potential applications. The qAOP used as an illustrative example for these points describes the linkage between inhibition of cytochrome P450 19A aromatase (the MIE) and population-level decreases in the fathead minnow (FHM; Pimephales promelas). The qAOP consists of three linked computational models for the following: (a) the hypothalamic-pitutitary-gonadal axis in female FHMs, where aromatase inhibition decreases the conversion of testosterone to 17β-estradiol (E2), thereby reducing E2-dependent vitellogenin (VTG; egg yolk protein precursor) synthesis, (b) VTG-dependent egg development and spawning (fecundity), and (c) fecundity-dependent population trajectory. While development of the example qAOP was based on experiments with FHMs exposed to the aromatase inhibitor fadrozole, we also show how a toxic equivalence (TEQ) calculation allows use of the qAOP to predict effects of another, untested aromatase inhibitor, iprodione. While qAOP development can be resource-intensive, the quan

Identification of risk factors for adverse obstetrical outcomes after appendectomy and cholecystectomy during pregnancy is necessary for evidence-based risk reduction and adequate patient counseling. To identify risk factors for adverse obstetrical outcomes after appendectomy and cholecystectomy during pregnancy and stratify the risk of such outcomes. A cohort study was conducted using the Nationwide Inpatient Sample, a nationally representative sample of patients discharged from community hospitals in the United States, from January 1, 2003, to December 31, 2012. Multivariable analysis of risk factors for adverse obstetric outcomes was performed for 19 926 women undergoing appendectomy or cholecystectomy during pregnancy and a scoring system for such risk factors was developed. Data analysis was conducted from January 1, 2015, to July 31, 2016. A composite measure including 7 adverse obstetrical outcomes throughout pregnancy and occurring before hospital discharge. Of the 19 926 women (mean [SD] age, 26 [6] years) in the study, 1018 adverse obstetrical events were recorded in 953 pregnant women (4.8%). The 3 most frequent adverse events were preterm delivery (360 [35.4%]), preterm labor without preterm delivery (269 [26.4%]), and miscarriage (262 [25.7%]). The risk factors associated most strongly with an adverse obstetrical outcome included cervical incompetence (adjusted odds ratio, 24.29; 95% CI, 7.48-78.81), preterm labor during current pregnancy (adjusted odds ratio, 18.34; 95% CI, 4.95-67.96), vaginitis or vulvovaginitis (adjusted odds ratio, 5.17; 95% CI, 2.19-12.23), and sepsis (adjusted odds ratio, 3.39; 95% CI, 2.08-5.51). A scoring system based on statistically significant variables classified the study sample into 3 risk groups corresponding to predicted probabilities of adverse obstetrical outcomes of 2.5% (≤4 points), 8.2% (5-8 points), and 21.8% (≥9 points). Approximately 5% of women experience adverse obstetrical outcomes after appendectomy

Mechanisms Underlying the Association Between Early-Life Adversity and Physical Health: Charting a Course for the Future.

PubMed

Bush, Nicole R; Lane, Richard D; McLaughlin, Katie A

Early-life adversities (ELA) are associated with subsequent pervasive alterations across a wide range of neurobiological systems and psychosocial factors that contribute to accelerated onset of health problems and diseases. In this article, we provide an integrated perspective on recent developments in research on ELA, based on the articles published in this Special Issue of Psychosomatic Medicine. We focus on the following: 1) the distinction between specific versus general aspects of ELA with regard to the nature of exposure (e.g., physical and sexual abuse, emotional abuse or neglect, relative socioeconomic deprivation), biological and behavioral correlates of ELA, and differences across diseases; 2) the importance of timing in the critical phases of exposure to ELA; and 3) adaptive versus dysfunctional responses to ELA and their consequences for biological and behavioral risk factors for adverse health outcomes. This article concludes with outlining important new targets for research in this area, including the neurobiology of affect as a mechanism linking ELA to adverse health outcomes, and the need for large-scale longitudinal investigations of multisystem processes relevant to ELA in diverse samples, starting prenatally, continuing to late adolescence, and with long-term follow-up assessments that enable evaluation of incident disease outcomes.

Cellulitis in obese patients is associated with increased rates of treatment failure compared to those with normal body mass index (BMI); however, patients have not been extensively studied in the outpatient environment or stratified based on range of obesity and associated risk factors. This study looked at antibiotic dosing and treatment failure in the obese population from the primary care perspective and accounts for BMI range, weight, comorbid diabetes, and tobacco use. This study was a retrospective chart review of 637 adult primary care patients designed to evaluate rates of treatment failure of outpatient cellulitis among patients of varying BMI. Treatment failure was defined as (a) hospital admission for intravenous antibiotics, (b) prolonged antibiotic course, or (c) requiring a different antibiotic after initial course. Adverse outcomes were not statistically significant between normal BMI and those with BMI ≥40 kg/m(2). A subset of patients with a BMI ≥50 kg/m(2) was noted to have approximately twice the rate of adverse outcomes as the normal BMI group. While controlling for age, gender, race, diagnosis of diabetes mellitus, and tobacco use, a BMI of ≥50 kg/m(2) and a weight ≥120 kg was associated with adverse outcomes with an odds ratio of 2.440 (95% CI, 1.260-4.724; P = .008) and 2.246 (95% CI, 1.154-4.369; P = .017), respectively. Patients with cellulitis weighing >120kg or with a BMI ≥50 kg/m(2) were at greatest risk for treatment failure in the outpatient setting, even when controlling for comorbid diabetes and tobacco use. As morbid obesity continues to become more prevalent, it becomes imperative that primary care physicians have better antibiotic dosing guidelines to account for the physiologic effects of obesity to minimize the risk of increased morbidity, health care costs, and antibiotic resistance. © The Author(s) 2015.

Maternal psychological distress during pregnancy does not increase the risk for adverse birth outcomes.

Maternal psychological distress during pregnancy is a potential risk factor for various birth complications. This study aimed to explore psychological factors associated with adverse birth outcomes. Symptoms of psychological distress, individual characteristics, and medical complications were assessed at two time points antenatally in 285 women from Australia and New Zealand; birth outcomes were assessed postpartum, between January 2014 and September 2015. Hierarchical multiple regression analyses were conducted to examine the relation of psychological distress to adverse birth outcomes. Medical complications during pregnancy, such as serious infections, placental problems and preeclampsia, and antenatal cannabis use, were the factors most strongly associated with adverse birth outcomes, accounting for 22 percent of the total variance (p < .001). Symptoms of depression and/or anxiety, low social support, and low sense of coherence were not associated with birth complications. In unadjusted analyses, self-reported diagnosis of anxiety disorder during pregnancy and an orientation toward a Regulator mothering style were associated with adverse birth outcomes; however, after controlling for medical complications, these were no longer associated. Our study results indicate that antenatal depressive and/or anxiety symptoms were not independently associated with adverse birth outcomes, a reassuring finding for women who are already psychologically vulnerable during pregnancy.

Childhood adversity is associated with a range of mental disorders, functional impairment and higher health care costs in adulthood. In this study we evaluated if childhood adversity was predictive of adverse clinical and functional outcomes and health care costs in a sample of patients at ultra-high risk (UHR) for developing a psychosis. Structural Equation Modeling was used to examine the effect of childhood adversity on depression, anxiety, transition to psychosis and overall functioning at 4-year follow-up. In addition, we evaluated economic costs of childhood adversity in terms of health care use and productivity loss. Data pertain to 105 UHR participants of the Dutch Early Detection and Intervention Evaluation (EDIE-NL). Physical abuse was associated with higher depression rates (b=0.381, p=0.012) and lower social functional outcome (b=-0.219, p=0.017) at 4-year follow-up. In addition, emotional neglect was negatively associated with social functioning (b=-0.313, p=0.018). We did not find evidence that childhood adversity was associated with transition to psychosis, but the experience of childhood adversity was associated with excess health care costs at follow-up. The data indicate long-term negative effects of childhood adversity on depression, social functioning and health care costs at follow-up in a sample of UHR patients.

Adverse Pregnancy Outcomes after Abnormal First Trimester Screening for Aneuploidy

Goetzl, Laura

2010-01-01

Women with abnormal first trimester screening but with a normal karyotype are at risk for adverse pregnancy outcomes. A nuchal translucency >3.5mm is associated with an increased risk of subsequent pregnancy loss, fetal infection, fetal heart abnormalities and other structural abnormalities. Abnormal first trimester analytes are also associated with adverse pregnancy outcomes but the predictive value is less impressive. As a single marker, PAPP-A <1st%ile has a good predictive value for subsequent fetal growth restriction. Women with PAPP-A<5th%ile should undergo subsequent risk assessment with routine MSAFP screening with the possible addition of uterine artery PI assessment in the midtrimester. PMID:20638576

The health outcomes of human offspring conceived by assisted reproductive technologies (ART).

Chen, M; Heilbronn, L K

2017-08-01

Concerns have been raised about the health and development of children conceived by assisted reproductive technologies (ART) since 1978. Controversially, ART has been linked with adverse obstetric and perinatal outcomes, an increased risk of birth defects, cancers, and growth and development disorders. Emerging evidence suggests that ART treatment may also predispose individuals to an increased risk of chronic ageing related diseases such as obesity, type 2 diabetes and cardiovascular disease. This review will summarize the available evidence on the short-term and long-term health outcomes of ART singletons, as multiple pregnancies after multiple embryos transfer, are associated with low birth weight and preterm delivery, which can separately increase risk of adverse postnatal outcomes, and impact long-term health. We will also examine the potential factors that may contribute to these health risks, and discuss underlying mechanisms, including epigenetic changes that may occur during the preimplantation period and reprogram development in utero, and adult health, later in life.

Objective Hypospadias is usually treated in childhood. Therefore, the natural history of untreated mild hypospadias is unknown. We hypothesized that men with untreated hypospadias, especially mild, do not have adverse outcomes. Materials Facebook was used to advertise an electronic survey to men older than 18 years. Men with untreated hypospadias identified themselves and indicated the severity of hypospadias with a series of questions. Outcomes included: Sexual Health Inventory for Men (SHIM), penile curvature and difficulty with intercourse, International Prostate Symptom Score (IPSS), Penile Perception Score (PPS), psychosexual milestones, paternity, infertility, sitting to urinate, and the CDC HRQOL-4 module. Results 736 men completed self-anatomy questions and 52 (7.1%) self-identified with untreated hypospadias. Untreated hypospadias participants reported worse SHIM (p < 0.001) and IPSS scores (p = 0.05), more ventral penile curvature (p = 0.003) and resulting difficulty with intercourse (p < 0.001), worse satisfaction with meatus (p = 0.011) and penile curvature (p = 0.048), and more sitting to urinate (p = 0.07). When stratified by mild and severe hypospadias, severe hypospadias was associated with more adverse outcomes than mild hypospadias. Conclusion Men with untreated hypospadias reported worse outcomes compared with non-hypospadiac men. Mild untreated hypospadias had fewer adverse outcomes than severe hypospadias. Research is needed to determine if treatment of childhood hypospadias improves outcomes in adults, especially for mild hypospadias. PMID:24613143

Although absolute counts of U.S. service men who experience sexual trauma are comparable to service women, little is known about the impact of sexual trauma on men. The association of recent sexual trauma (last 3 years) with health and occupational outcomes was investigated using longitudinal data (2004-2013) from the Millennium Cohort Study. Of 37,711 service men, 391 (1.0%) reported recent sexual harassment and 76 (0.2%) sexual assault. In multivariable models, sexual harassment or assault, respectively, was associated with poorer mental health: AOR = 1.60, 95% CI [1.22, 2.12], AOR = 4.39, 95% CI [2.40, 8.05]; posttraumatic stress disorder: AOR = 2.50, 95% CI [1.87, 3.33], AOR = 6.63, 95% CI [3.65, 12.06]; depression: AOR = 2.37, 95% CI [1.69, 3.33], AOR = 5.60, 95% CI [2.83, 11.09]; and multiple physical symptoms: AOR = 2.22, 95% CI [1.69, 2.92]; AOR = 3.57, 95% CI [1.98, 6.42], after adjustment for relevant covariates. Sexual harassment was also associated with poorer physical health: AOR = 1.68, 95% CI [1.27, 2.22]. Men who reported sexual trauma were more likely to have left military service: AOR = 1.60, 95% CI [1.14, 2.24], and be disabled/unemployed postservice: AOR = 1.76, 95% CI [1.02, 3.02]. Results suggest that sexual trauma was significantly associated with adverse health and functionality extending to postmilitary life. Findings support the need for developing better prevention strategies and services to reduce the burden of sexual trauma on service men.

In 2009, a paper was published suggesting that watersheds provide a geospatial platform for establishing linkages between aquatic contaminants, the health of the environment, and human health. This article is a follow-up to that original article. From an environmental perspective, watersheds segregate landscapes into geospatial units that may be relevant to human health outcomes. From an epidemiologic perspective, the watershed concept places anthropogenic health data into a geospatial framework that has environmental relevance. Research discussed in this article includes information gathered from the literature, as well as recent data collected and analyzed by this research group. It is our contention that the use of watersheds to stratify geospatial information may be both environmentally and epidemiologically valuable. PMID:29398918

Importance Identification of risk factors for adverse obstetrical outcomes after appendectomy and cholecystectomy during pregnancy is necessary for evidence-based risk reduction and adequate patient counseling. Objectives To identify risk factors for adverse obstetrical outcomes after appendectomy and cholecystectomy during pregnancy and stratify the risk of such outcomes. Design, Setting, and Participants A cohort study was conducted using the Nationwide Inpatient Sample, a nationally representative sample of patients discharged from community hospitals in the United States, from January 1, 2003, to December 31, 2012. Multivariable analysis of risk factors for adverse obstetric outcomes was performed for 19 926 women undergoing appendectomy or cholecystectomy during pregnancy and a scoring system for such risk factors was developed. Data analysis was conducted from January 1, 2015, to July 31, 2016. Main Outcomes and Measures A composite measure including 7 adverse obstetrical outcomes throughout pregnancy and occurring before hospital discharge. Results Of the 19 926 women (mean [SD] age, 26 [6] years) in the study, 1018 adverse obstetrical events were recorded in 953 pregnant women (4.8%). The 3 most frequent adverse events were preterm delivery (360 [35.4%]), preterm labor without preterm delivery (269 [26.4%]), and miscarriage (262 [25.7%]). The risk factors associated most strongly with an adverse obstetrical outcome included cervical incompetence (adjusted odds ratio, 24.29; 95% CI, 7.48-78.81), preterm labor during current pregnancy (adjusted odds ratio, 18.34; 95% CI, 4.95-67.96), vaginitis or vulvovaginitis (adjusted odds ratio, 5.17; 95% CI, 2.19-12.23), and sepsis (adjusted odds ratio, 3.39; 95% CI, 2.08-5.51). A scoring system based on statistically significant variables classified the study sample into 3 risk groups corresponding to predicted probabilities of adverse obstetrical outcomes of 2.5% (≤4 points), 8.2% (5-8 points), and 21.8% (≥9

Examine whether health information technology (HIT) at nonhospital facilities (NHFs) improves health outcomes and decreases resource use at hospitals within the same heath care network, and whether the impact of HIT varies as providers gain experience using the technologies. Administrative claims data on 491,832 births in Pennsylvania during 1998-2004 from the Pennsylvania Health Care Cost Containment Council and HIT applications data from the Dorenfest Institute. Fixed-effects regression analysis of the impact of HIT at NHFs on adverse birth outcomes and resource use. Greater use of clinical HIT applications by NHFs is associated with reduced incidence of obstetric trauma and preventable complications, as well as longer lengths of stay. In addition, the beneficial effects of HIT increase the longer that technologies have been in use. However, we find no consistent evidence on whether or how nonclinical HIT in NHFs affects either resource use or health outcomes. Clinical HIT applications at NHFs may reduce the likelihood of adverse birth outcomes, particularly after physicians and staff gain experience using the technologies. © Health Research and Educational Trust.

Background Several studies have linked marijuana use with a variety of health outcomes among young adults. Information about marijuana’s long-term health effects is critically needed. Methods Data are from a ten-year study of 1,253 young adults originally recruited as first-year college students and assessed annually thereafter. Six trajectories of marijuana use during college (Non-Use, Low-Stable, Early-Decline, College-Peak, Late-Increase, Chronic) were previously derived using latent variable growth mixture modeling. Nine health outcomes assessed in Year 10 (modal age 27) were regressed on a group membership variable for the six group trajectories, holding constant demographics, baseline health status, and alcohol and tobacco trajectory group membership. Results Marijuana trajectory groups differed significantly on seven of the nine outcomes (functional impairment due to injury, illness, or emotional problems; psychological distress; subjective well-being; and mental and physical health service utilization; all ps<.001), but not on general health rating or body mass index. Non-Users fared better than the Late-Increase and Chronic groups on most physical and mental health outcomes. The declining groups (Early-Decline, College-Peak) fared better than the Chronic group on mental health outcomes. The Late-Increase group fared significantly worse than the stable groups (Non-Use, Low-Stable, Chronic) on both physical and mental health outcomes. Conclusions Even occasional or time-limited marijuana use might have adverse effects on physical and mental health, perhaps enduring after several years of moderation or abstinence. Reducing marijuana use frequency might mitigate such effects. Individuals who escalate their marijuana use in their early twenties might be at especially high risk for adverse outcomes.

It is well documented that childhood abuse, neglect and household dysfunction are disproportionately present in the backgrounds of homeless adults, and that these experiences adversely impact child development and a wide range of adult outcomes. However, few studies have examined the cumulative impact of adverse childhood experiences on homeless adults with mental illness. This study examines adverse events in childhood as predictors of duration of homelessness, psychiatric and substance use disorders, and physical health in a sample of homeless adults with mental illness. This study was conducted using baseline data from a randomized controlled trial in Vancouver, British Columbia for participants who completed the Adverse Childhood Experiences (ACE) scale at 18 months follow-up (n=364). Primary outcomes included current mental disorders; substance use including type, frequency and severity; physical health; duration of homelessness; and vocational functioning. In multivariable regression models, ACE total score independently predicted a range of mental health, physical health, and substance use problems, and marginally predicted duration of homelessness. Adverse childhood experiences are overrepresented among homeless adults with complex comorbidities and chronic homelessness. Our findings are consistent with a growing body of literature indicating that childhood traumas are potent risk factors for a number of adult health and psychiatric problems, particularly substance use problems. Results are discussed in the context of cumulative adversity and self-trauma theory. This trial has been registered with the International Standard Randomized Control Trial Number Register and assigned ISRCTN42520374.

To characterize the relationship between HbA 1c variability and adverse health outcomes among US military veterans with Type 2 diabetes. This retrospective cohort study used Veterans Affairs and Medicare claims for veterans with Type 2 diabetes taking metformin who initiated a second diabetes medication (n = 50 861). The main exposure of interest was HbA 1c variability during a 3-year baseline period. HbA 1c variability, categorized into quartiles, was defined as standard deviation, coefficient of variation and adjusted standard deviation, which accounted for the number and mean number of days between HbA 1c tests. Cox proportional hazard models predicted mortality, hospitalization for ambulatory care-sensitive conditions, and myocardial infarction or stroke and were controlled for mean HbA 1c levels and the direction of change in HbA 1c levels during the baseline period. Over a mean 3.3 years of follow-up, all HbA 1c variability measures significantly predicted each outcome. Using the adjusted standard deviation measure for HbA 1c variability, the hazard ratios for the third and fourth quartile predicting mortality were 1.14 (95% CI 1.04, 1.25) and 1.42 (95% CI 1.28, 1.58), for myocardial infarction and stroke they were 1.25 (95% CI 1.10, 1.41) and 1.23 (95% CI 1.07, 1.42) and for ambulatory-care sensitive condition hospitalization they were 1.10 (95% CI 1.03, 1.18) and 1.11 (95% CI 1.03, 1.20). Higher baseline HbA 1c levels independently predicted the likelihood of each outcome. In veterans with Type 2 diabetes, greater HbA 1c variability was associated with an increased risk of adverse long-term outcomes, independently of HbA 1c levels and direction of change. Limiting HbA 1c fluctuations over time may reduce complications. © 2016 Diabetes UK.

THE ADVERSE OUTCOME PATHWAY (AOP) FRAMEWORK ...

EPA Pesticide Factsheets

An Adverse Outcome Pathway (AOP) represents the organization of current and newly acquired knowledge of biological pathways. These pathways contain a series of nodes (Key Events, KEs) that when sufficiently altered influence the next node on the pathway, beginning from an Molecular Initiating Event (MIE), through intermediate KEs, ending in an Adverse Outcome (AO) which may be used as a basis for decision making. A KE is a measurable biological change, and is linked with other KEs via Key Event Relationships (KERs). A given KE may be involved in several AOPs, leading to a plausible network of biological changes that are involved in an organism’s response to an external stressor. When describing an AOP, five guiding principles have been proposed [1]: 1) an AOP is not specific to a single external stressor, 2) AOPs are modular, with KEs and KERs that can be used in several AOPs, 3) a single AOP is the unit of development, 4) most biological responses will be the result of networks of AOPs, and 5) AOPs will be modified as more biological knowledge becomes available. The collaborative development of AOPs is recommended to be performed using the AOP-Wiki (https://aopwiki.org), which is an effort between the European Commission – DG Joint Research Centre (JRC) and U.S. Environmental Protection Agency (EPA). The Wiki is one part of a larger OECD-sponsored AOP Knowledgebase effort, which is a repository for all AOPs developed as part of the Organization for Economic

PUTATIVE ADVERSE OUTCOME PATHWAY FOR INHIBITON ...

EPA Pesticide Factsheets

The adverse outcome pathway (AOP) provides a framework for organizing knowledge to define links between a molecular initiating event (MIE) and an adverse outcome (AO) occurring at a higher level of biological organization, such as the individual or population. The AOP framework proceeds from a general (e.g., not chemical specific) molecular mode of action, designated as a MIE, through stepwise changes in biological status, defined as key events (KEs), to a final AO that can be used in risk assessment. Because aromatase-inhibiting pharmaceuticals are widely used to treat breast cancer patients, we explored the unintended consequences that might occur in fish exposed to these chemicals through wastewater discharge into the aquatic environment. Unlike mammals, fish have two isoforms of aromatase, one that predominates in the ovary (cyp19a1a) and a second (cyp19a1b) that prevails in the brain. Aromatase activity in fish brain can be 100 to 1000 times that in mammals and is associated with reproduction. We have developed a putative AOP for inhibition of brain aromatase in fish leading to reproductive dysfunction based on review of relevant literature and reproductive experiments with the marine fish cunner (Tautogolabrus adspersus) exposed to aromatase-inhibiting pharmaceuticals in the laboratory. The first KE in this AOP is a decrease in brain aromatase activity due to exposure to an aromatase inhibitor. KEs then progress through subsequent steps including decreas

The steeling effect suggests that early-life adversity can have a beneficial impact later in life. However, little is known about its underlying mechanisms and long-term outcomes . The study aimed to examine the role of early-life adversity (ELA) on successful aging, and whether this relationship can be explained by mental and physical health. Socio-demographics, early-life adversity (ELA), individual quality of life (iQoL), and mental and physical health of 270 individuals (M age = 66.82 years, 71.5% female) were assessed. Polynomial regressions and mediation analyses were conducted. Significant inverse U-shaped associations were found between ELA and iQoL (β = -.59, p = .005) and between ELA and mental health (β = -.64, p = .002), but not between ELA and physical health. Furthermore, mental health significantly mediated the relationship between ELA and iQoL (b = -.84, BCa CI [-1.66, -.27]). Highest level of individual quality of life (i.e. successful aging) was related to a moderate amount of ELA. Additionally, mental health significantly mediated this relationship. These findings suggest that some amount of ELA could be beneficial for successful aging. Resource-focused interventions are needed to improve health and promote successful aging for an underdetected, at-risk subgroup with low early-life adversity.

Objective The purpose of this study is to determine the frequency of adverse perinatal outcome in women with hyperemesis gravidarum and identify prognostic factors. Study design This is a case-control study in which outcomes of first pregnancies were compared between 254 women with hyperemesis gravidarum treated with intravenous fluids and 308 controls. Prognostic factors were identified by comparing the clinical profile of patients with hyperemesis gravidarum with a normal and an adverse pregnancy outcome. Binary responses were analyzed using either a Chi-square or Fisher exact test and continuous responses were analyzed using a t-test. Results Women with hyperemesis gravidarum have over a 4-fold increased risk of poor outcome including preterm birth and lower birth weight (p < 0.0001). Among maternal characteristics, only gestational hypertension had an influence on outcome (p < 0.0001). Treatment as an outpatient and/or by alternative medicine (acupuncture/acupressure/Bowen massage) was associated with a positive outcome (p < 0.0089). Poor outcomes were associated with early start of symptoms (p < 0.019), and treatment with methylprednisolone (p < 0.0217), promethazine (p < 0.0386), and other antihistamines [diphenhy- dramine (Benadryl), dimenhydrinate (Gravol), doxylamine (Unisom), hydroxyzine (Vistaril/Atarax), doxylamine and pyridoxine (Diclectin/Bendectin)] (p < 0.0151) independent of effectiveness. Among these medications, only the other antihistamines were prescribed independent of severity: they were effective in less than 20% of cases and were taken by almost 50% of patients with an adverse outcome. Conclusion Poor outcomes are significantly greater in women with HG and are associated with gestational hypertension, early symptoms, and antihistamine use. Given these results, there is an urgent need to address the safety and effectiveness of medications containing antihistamines in women with severe nausea of pregnancy. PMID:23751910

Oil and natural gas operations have been shown to contaminate surface and ground water with endocrine-disrupting chemicals. In the current study, we fill several gaps in our understanding of the potential environmental impacts related to this process. We measured the endocrine-disrupting activities of 24 chemicals used and/or produced by oil and gas operations for five nuclear receptors using a reporter gene assay in human endometrial cancer cells. We also quantified the concentration of 16 of these chemicals in oil and gas wastewater samples. Finally, we assessed reproductive and developmental outcomes in male C57BL/6J mice after the prenatal exposure to a mixture of these chemicals. We found that 23 commonly used oil and natural gas operation chemicals can activate or inhibit the estrogen, androgen, glucocorticoid, progesterone, and/or thyroid receptors, and mixtures of these chemicals can behave synergistically, additively, or antagonistically in vitro. Prenatal exposure to a mixture of 23 oil and gas operation chemicals at 3, 30, and 300 μg/kg · d caused decreased sperm counts and increased testes, body, heart, and thymus weights and increased serum testosterone in male mice, suggesting multiple organ system impacts. Our results suggest possible adverse developmental and reproductive health outcomes in humans and animals exposed to potential environmentally relevant levels of oil and gas operation chemicals.

Do sugar-sweetened beverages cause adverse health outcomes in children? A systematic review protocol

PubMed Central

2014-01-01

Background Cardiovascular disease and type 2 diabetes are examples of chronic diseases that impose significant morbidity and mortality in the general population worldwide. Most chronic diseases are associated with underlying preventable risk factors, such as elevated blood pressure, high blood glucose or glucose intolerance, high lipid levels, physical inactivity, excessive sedentary behaviours, and overweight/obesity. The occurrence of intermediate outcomes during childhood increases the risk of disease in adulthood. Sugar-sweetened beverages are known to be significant sources of additional caloric intake, and given recent attention to their contribution in the development of chronic diseases, a systematic review is warranted. We will assess whether the consumption of sugar-sweetened beverages in children is associated with adverse health outcomes and what the potential moderating factors are. Methods/Design Of interest are studies addressing sugar-sweetened beverage consumption, taking a broad perspective. Both direct consumption studies as well as those evaluating interventions that influence consumption (e.g. school policy, educational) will be relevant. Non-specific or multi-faceted behavioural, educational, or policy interventions may also be included subject to the level of evidence that exists for the other interventions/exposures. Comparisons of interest and endpoints of interest are pre-specified. We will include randomized controlled trials, controlled clinical trials, interrupted time series studies, controlled before-after studies, prospective and retrospective comparative cohort studies, case–control studies, and nested case–control designs. The MEDLINE®, Embase, The Cochrane Library, CINAHL, ERIC, and PsycINFO® databases and grey literature sources will be searched. The processes for selecting studies, abstracting data, and resolving conflicts are described. We will assess risk of bias using design-specific tools. To determine sets of

Intimate partner violence (IPV) affects an estimated 1.5 million U.S. women annually. IPV impacts maternal and neonatal health with higher rates of depression and low birth weight (LBW). Less studied is experiencing IPV and delivering a small for gestational age (SGA) baby. SGA neonates are at increased risk of developmental and behavioral problems. The negative sequelae persist into adulthood with increased rates of diabetes mellitus and coronary heart disease. In a sample of 239 pregnant women experiencing IPV, in urban and rural settings, we examined cross-sectional associations of severity of IPV and neonatal outcomes (i.e., birth weight and gestational age). Severity of IPV was measured by the Conflict Tactics Scale 2 and neonatal outcomes were collected at the time of delivery. Outcomes were collected on 194 neonates; 14.9% (n=29) were classified as LBW, 19.1% (n=37) classified as SGA, and 9.8% (n=19) as LBW and SGA. Women reporting higher severity of IPV during pregnancy had a greater likelihood of delivering an SGA neonate (odds ratio [OR] 4.81; 95% confidence interval [95% CI] 1.86-12.47), and LBW neonate (OR 4.20; 95% CI 1.46-12.10). In a sample of pregnant women experiencing perinatal IPV, women experiencing greater severities of IPV were more likely to deliver a neonate with an adverse outcome. Early recognition and intervention of IPV is essential to reduce disparities in birth outcomes and long-term health outcomes for these neonates.

Adverse Health Consequences of Performance-Enhancing Drugs: An Endocrine Society Scientific Statement

2014-01-01

Despite the high prevalence of performance-enhancing drug (PED) use, media attention has focused almost entirely on PED use by elite athletes to illicitly gain a competitive advantage in sports, and not on the health risks of PEDs. There is a widespread misperception that PED use is safe or that adverse effects are manageable. In reality, the vast majority of PED users are not athletes but rather nonathlete weightlifters, and the adverse health effects of PED use are greatly underappreciated. This scientific statement synthesizes available information on the medical consequences of PED use, identifies gaps in knowledge, and aims to focus the attention of the medical community and policymakers on PED use as an important public health problem. PED users frequently consume highly supraphysiologic doses of PEDs, combine them with other PEDs and/or other classical drugs of abuse, and display additional associated risk factors. PED use has been linked to an increased risk of death and a wide variety of cardiovascular, psychiatric, metabolic, endocrine, neurologic, infectious, hepatic, renal, and musculoskeletal disorders. Because randomized trials cannot ethically duplicate the large doses of PEDs and the many factors associated with PED use, we need observational studies to collect valid outcome data on the health risks associated with PEDs. In addition, we need studies regarding the prevalence of PED use, the mechanisms by which PEDs exert their adverse health effects, and the interactive effects of PEDs with sports injuries and other high-risk behaviors. We also need randomized trials to assess therapeutic interventions for treating the adverse effects of PEDs, such as the anabolic-androgen steroid withdrawal syndrome. Finally, we need to raise public awareness of the serious health consequences of PEDs. PMID:24423981

The aim of this study was to determine whether prenatal variables can predict adverse neonatal outcomes in fetuses with abdominal wall defects. A retrospective cohort study that used ultrasound and neonatal records for all cases of gastroschisis and omphalocele seen over a 16-year period. Cases with adverse neonatal outcomes were compared with noncases for multiple candidate predictive factors. Univariable and multivariable statistical methods were used to develop the prediction models, and effectiveness was evaluated using the area under the receiver operating characteristic curve. Of 80 fetuses with gastroschisis, 29 (36%) had the composite adverse outcome, compared with 15 of 33 (47%) live neonates with omphalocele. Intrauterine growth restriction was the only significant variable in gastroschisis, whereas exteriorized liver was the only predictor in omphalocele. The areas under the curve for the prediction models with gastroschisis and omphalocele are 0.67 and 0.74, respectively. Intrauterine growth restriction and exteriorization of the liver are significant predictors of adverse neonatal outcome with gastroschisis and omphalocele.

To determine whether intertwin discordant abdominal circumference, femur length, head circumference, and estimated fetal weight sonographic measurements in early second-trimester monochorionic diamniotic twins predict adverse obstetric and neonatal outcomes. We conducted a multicenter retrospective cohort study involving 9 regional perinatal centers in the United States. We examined the records of all monochorionic diamniotic twin pregnancies with two live fetuses at the 16- to 18-week sonographic examination who had serial follow-up sonography until delivery. The intertwin discordance in abdominal circumference, femur length, head circumference, and estimated fetal weight was calculated as the difference between the two fetuses, expressed as a percentage of the larger using the 16- to 18-week sonographic measurements. An adverse composite obstetric outcome was defined as the occurrence of 1 or more of the following in either fetus: intrauterine growth restriction, twin-twin transfusion syndrome, intrauterine fetal death, abnormal growth discordance (≥20% difference), and very preterm birth at or before 28 weeks. An adverse composite neonatal outcome was defined as the occurrence of 1 or more of the following: respiratory distress syndrome, any stage of intraventricular hemorrhage, 5-minute Apgar score less than 7, necrotizing enterocolitis, culture-proven early-onset sepsis, and neonatal death. Receiver operating characteristic and logistic regression-with-generalized estimating equation analyses were constructed. Among the 177 monochorionic diamniotic twin pregnancies analyzed, intertwin abdominal circumference and estimated fetal weight discordances were only predictive of adverse composite obstetric outcomes (areas under the curve, 79% and 80%, respectively). Receiver operating characteristic curves showed that intertwin discordances in abdominal circumference, femur length, head circumference, and estimated fetal weight were not acceptable predictors of twin

Objective Examine whether health information technology (HIT) at nonhospital facilities (NHFs) improves health outcomes and decreases resource use at hospitals within the same heath care network, and whether the impact of HIT varies as providers gain experience using the technologies. Data Sources Administrative claims data on 491,832 births in Pennsylvania during 1998–2004 from the Pennsylvania Health Care Cost Containment Council and HIT applications data from the Dorenfest Institute. Study Design Fixed-effects regression analysis of the impact of HIT at NHFs on adverse birth outcomes and resource use. Principal Findings Greater use of clinical HIT applications by NHFs is associated with reduced incidence of obstetric trauma and preventable complications, as well as longer lengths of stay. In addition, the beneficial effects of HIT increase the longer that technologies have been in use. However, we find no consistent evidence on whether or how nonclinical HIT in NHFs affects either resource use or health outcomes. Conclusions Clinical HIT applications at NHFs may reduce the likelihood of adverse birth outcomes, particularly after physicians and staff gain experience using the technologies. PMID:22742682

Hypospadias is usually treated in childhood. Therefore, the natural history of untreated mild hypospadias is unknown. We hypothesized that men with untreated hypospadias, especially mild, do not have adverse outcomes. Facebook was used to advertise an electronic survey to men older than 18 years. Men with untreated hypospadias identified themselves and indicated the severity of hypospadias with a series of questions. Outcomes included: Sexual Health Inventory for Men (SHIM), penile curvature and difficulty with intercourse, International Prostate Symptom Score (IPSS), Penile Perception Score (PPS), psychosexual milestones, paternity, infertility, sitting to urinate, and the CDC HRQOL-4 module. 736 men completed self-anatomy questions and 52 (7.1%) self-identified with untreated hypospadias. Untreated hypospadias participants reported worse SHIM (p < 0.001) and IPSS scores (p = 0.05), more ventral penile curvature (p = 0.003) and resulting difficulty with intercourse (p < 0.001), worse satisfaction with meatus (p = 0.011) and penile curvature (p = 0.048), and more sitting to urinate (p = 0.07). When stratified by mild and severe hypospadias, severe hypospadias was associated with more adverse outcomes than mild hypospadias. Men with untreated hypospadias reported worse outcomes compared with non-hypospadiac men. Mild untreated hypospadias had fewer adverse outcomes than severe hypospadias. Research is needed to determine if treatment of childhood hypospadias improves outcomes in adults, especially for mild hypospadias. Copyright © 2014 Journal of Pediatric Urology Company.

While association between endometriosis and infertility is well established, there are few studies about the impact of endometriosis on adverse pregnancy outcomes. The aim of this study was to determine the effect of endometriosis on obstetric outcomes and whether the severity of the disease had an influence on these. We performed a retrospective study to investigate the obstetric outcomes of a population of 1204 subfertile women, including 258 with endometriosis, who obtained, thanks to assisted reproduction technology, a singleton pregnancy evolving beyond embryonic stage. Two analyzes were performed. The first compared women with endometriosis to women with other causes of infertility. The second observed adverse pregnancy outcomes according to AFS-R stages of endometriosis. The overall rate of live birth children was 95.8%. In case of endometriosis, there was a significant increase of the incidence of preterm delivery, especially before 32 weeks amenorrhea (6.2% vs 3.1% in the group "without endometriosis", P = 0.03), antenatal bleeding (5.3% vs 2.2%, P = 0.01) and placenta previa (4.9% vs 0.9%, P < 0.0001). The incidence of gestational diabetes was significantly decreased (0.4% vs 2.7%, P = 0.04). There was no correlation between endometriosis and cesarean section or preeclampsia, or between the AFS-R stage and adverse pregnancy outcomes. Endometriosis is a factor of obstetrical risk, independently of the infertility it causes. The AFS-R score does not seem to be representative of obstetric outcomes beyond first trimester of pregnancy for women with endometriosis. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

The Adverse Outcome Pathway (AOP) concept has recently been proposed to support a paradigm shift in regulatory toxicology testing and risk assessment. This concept is similar to the Mode of Action (MOA), in that it describes a sequence of measurable key events triggered by a molecular initiating event in which a stressor interacts with a biological target. The resulting cascade of key events includes molecular, cellular, structural and functional changes in biological systems, resulting in a measurable adverse outcome. Thereby, an AOP ideally provides information relevant to chemical structure-activity relationships as a basis for predicting effects of structurally similar compounds. AOPs could potentially also form the basis for qualitative and quantitative predictive modeling of the human adverse outcome resulting from molecular initiating or other key events for which higher-throughput testing methods are available or can be developed. A variety of cellular and molecular processes are known to be critical for normal function of the central (CNS) and peripheral nervous systems (PNS). Because of the biological and functional complexity of the CNS and PNS, it has been challenging to establish causative links and quantitative relationships between key events that comprise the pathways leading from chemical exposure to an adverse outcome in the nervous system. Following introduction of the principles of MOA and AOPs, examples of potential or putative adverse outcome pathways specific for developmental or adult neurotoxicity are summarized and aspects of their assessment considered. Their possible application in developing mechanistically informed Integrated Approaches to Testing and Assessment (IATA) is also discussed. PMID:27212452

We aimed to report the first 54 cases of pregnant women infected by Zika virus (ZIKV) and their virologic and clinical outcomes, as well as their newborns' outcomes, in 2016, after the emergence of ZIKV in dengue-endemic areas of São Paulo, Brazil. This descriptive study was performed from February to October 2016 on 54 quantitative real-time PCR ZIKV-positive pregnant women identified by the public health authority of São José do Rio Preto, São Paulo, Brazil. The women were followed and had clinical and epidemiologic data collected before and after birth. Adverse outcomes in newborns were analysed and reported. Urine or blood samples from newborns were collected to identify ZIKV infection by reverse transcription PCR (RT-PCR). A total of 216 acute Zika-suspected pregnant women were identified, and 54 had the diagnosis confirmed by RT-PCR. None of the 54 women miscarried. Among the 54 newborns, 15 exhibited adverse outcomes at birth. The highest number of ZIKV infections occurred during the second and third trimesters. No cases of microcephaly were reported, though a broad clinical spectrum of outcomes, including lenticulostriate vasculopathy, subependymal cysts, and auditory and ophthalmologic disorders, were identified. ZIKV RNA was detected in 18 of 51 newborns tested and in eight of 15 newborns with adverse outcomes. Although other studies have associated many newborn outcomes to ZIKV infection during pregnancy, these same adverse outcomes were rare or nonexistent in this study. The clinical presentation the newborns we studied was mild compared to other reports, suggesting that there is significant heterogeneity in congenital Zika infection.

2018-04-20

A facultative post market monitoring of potential health impacts of genetically modified (GM) feedstuffs on livestock consuming these feeds after pre-market risk assessment is under ongoing consideration. Within the IPAFEED database, scientific studies on health effects beyond performance in livestock and the results of a systematic search for evidence of outcome effects due to GM feed are consolidated. These outcomes were reviewed and checked for consistency in order to identify plausible syndromes suitable for conducting surveillance. The 24 selected studies showed no consistent changes in any health parameter. There were no repeated studies in any species by GM crop type and animal species. As such, there is insufficient evidence to inform the design of surveillance systems for detecting known adverse effects. Animal health surveillance systems have been proposed for the post market monitoring of potential adverse effects in animals. Such systems were evaluated for their applicability to the detection of hypothetical adverse effects and their strengths and weaknesses to detect syndromes of concern are presented. For known adverse effects, applied controlled post-market studies may yield conclusive and high-quality evidence. For detecting unknown adverse effects, the use of existing surveillance systems may still be of interest. A simulation tool developed within the project can be adapted and applied to existing surveillance systems to explore their applicability to the detection of potential adverse effects of GM feed.

The scope of this article was to investigate whether intercessory prayer (IP) influences the adverse outcomes of pregnancies. A double-blind, randomized clinical trial was conducted with 564 pregnant women attending a prenatal public health care service. The women were randomly assigned to an IP group or to a control group (n = 289 per group). They were simultaneously and randomly assigned to practice prayer off-site or not. The following parameters were evaluated: Apgar scores, type of delivery and birth weight. The mean age of the women was 25.1 years of age (± 7.4), and the average gestational age was 23.4 weeks (± 8.1). The average number of years of schooling for the women was 8.1 years (± 3.1). The women in the IP and control groups presented a similar number of adverse medical events with non-significant p. No significant differences were detected in the frequency of adverse outcomes in pregnant women who practiced IP and those in the control group.

Skilled migration and health outcomes in developing countries.

PubMed

Uprety, Dambar

2018-04-30

Many studies have found that health outcomes decline when health professionals leave the country, but do such results remain consistent in gender- and income-disaggregated skilled migration? To help uncover explanations for such a pro-migration nature of health outcomes, the present study revisits this topic but allows for associations of skilled migration with mortality and life expectancy to differ between male and female, and between low- and high-income countries. Using a panel of 133 developing countries as source and 20 OECD countries as destination from 1980 to 2010 allowing the coefficient on emigration across different education levels to differ, the study finds the negative effect of high-skilled emigration on health outcomes. Such effect is more pronounced for high-skilled female migration than those for male and for low-income countries than for middle-and high-income countries. Results also show that such adverse effect is larger for African countries than non-African ones. However, the low-skilled migration appears to be insignificant to affect health outcomes in developing countries. Thus, skilled migration is detrimental to longevity in developing countries but unskilled migration is not.

Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism and subfertility, but the effects on mental health and child neurodevelopment are unclear. To determine if (1) there is an association between PCOS and psychiatric outcomes and (2) whether rates of autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) are higher in children of mothers with PCOS. Data were extracted from the Clinical Practice Research Datalink. Patients with PCOS were matched to two control sets (1:1) by age, body mass index, and primary care practice. Control set 2 was additionally matched on prior mental health status. Primary outcomes were the incidence of depression, anxiety, and bipolar disorder. Secondary outcomes were the prevalence of ADHD or ASD in the children. Eligible patients (16,986) were identified; 16,938 and 16,355 were matched to control sets 1 and 2, respectively. Compared with control set 1, baseline prevalence was 23.1% vs 19.3% for depression, 11.5% vs 9.3% for anxiety, and 3.2% vs 1.5% for bipolar disorder (P < 0.001). The hazard ratio for time to each endpoint was 1.26 (95% confidence interval 1.19 to 1.32), 1.20 (1.11 to 1.29), and 1.21 (1.03 to 1.42) for set 1 and 1.38 (1.30 to 1.45), 1.39 (1.29 to 1.51), and 1.44 (1.21 to 1.71) for set 2. The odds ratios for ASD and ADHD in children were 1.54 (1.12 to 2.11) and 1.64 (1.16 to 2.33) for set 1 and 1.76 (1.27 to 2.46) and 1.34 (0.96 to 1.89) for set 2. PCOS is associated with psychiatric morbidity and increased risk of ADHD and ASD in their children. Screening for mental health disorders should be considered during assessment.

[Adverse birth outcomes of maternal smoking during pregnancy and genetic polymorphisms: exploiting gene-environment interaction].

It has been recognized that metabolic enzymes mediating genetic susceptibility to environmental chemicals such as polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans and polychlorinated biphenyls might be related to adverse human health. Recent studies, including the Hokkaido Study of Environmental and Children's Health, have shown that metabolic enzymes mediating genetic susceptibility to environmental chemicals including tobacco smoke might be related to adverse birth outcomes. Certain maternal genetic polymorphisms in the polycyclic aromatic hydrocarbons (PAHs)-metabolizing enzymes have been shown to enhance the association between maternal smoking and infant birth weight in both Caucasians and Japanese. For maternal genetic polymorphisms encoding the N-nitrosamine-metabolizing enzymes, we found that infant birth weight, birth length and birth head circumference were significantly smaller among infants of smokers than among those of nonsmokers and quitters. The adverse effects of maternal smoking on infant birth size may be modified by maternal genetic polymorphisms. Further study is required to clarify the potential association between genetic polymorphisms and cognitive function in childhood, becauae it has been reported that a small birth length or a small head circumference at birth might affect neurobehavioral development during early childhood. It is necessary to elucidate additive impacts of genetic factors on adverse effects of various chemicals commonly encountered in our daily lives, follow up the development of children, and carry out longitudinal observation.

Illicit drug use and adverse birth outcomes: is it drugs or context?

PubMed

Schempf, Ashley H; Strobino, Donna M

Prenatal drug use is commonly associated with adverse birth outcomes, yet no studies have controlled for a comprehensive set of associated social, psychosocial, behavioral, and biomedical risk factors. We examined the degree to which adverse birth outcomes associated with drug use are due to the drugs versus surrounding factors. Data are from a clinical sample of low-income women who delivered at Johns Hopkins Hospital between 1995 and 1996 (n = 808). Use of marijuana, cocaine, and opiates was determined by self-report, medical record, and urine toxicology screens at delivery. Information on various social, psychosocial, behavioral, and biomedical risk factors was gathered from a postpartum interview or the medical record. Multivariable regression models of birth outcomes (continuous birth weight and low birth weight ([LBW] < 2,500 g)) were used to assess the effect of drug use independent of associated factors. In unadjusted results, all types of drug use were related to birth weight decrements and increased odds of LBW. However, only the effect of cocaine on continuous birth weight remained significant after adjusting for all associated factors (-142 g, p = 0.05). No drug was significantly related to LBW in fully adjusted models. About 70% of the unadjusted effect of cocaine use on continuous birth weight was explained by surrounding psychosocial and behavioral factors, particularly smoking and stress. Most of the unadjusted effects of opiate use were explained by smoking and lack of early prenatal care. Thus, prevention efforts that aim to improve newborn health must also address the surrounding context in which drug use frequently occurs.

Research has revealed that a lack of insight is associated with poorer clinical outcomes in schizophrenia; however, the predictive value of insight on adverse clinical outcomes among bipolar patients is quite understudied. The aim of this prospective study was to examine the impact of insight on adverse clinical outcomes among the patients with bipolar I disorder over a 2-year period. Sixty-five remitted bipolar I disorder patients received follow-up assessments at 3, 6, 9, 12, 18, and 24 months to detect the adverse clinical outcomes defined by the incidence of bipolar-related psychiatric hospitalization, emergency room visits, violent or suicidal behavior. The Schedule of Assessment of Insight was used to provide a baseline insight score. Cox regression analysis was used to examine the predictive value of insight on the adverse clinical outcomes. Impaired insight into treatment and a greater number of previous hospitalizations significantly increased the risk of adverse clinical outcomes with bipolar disorder in the 2-year period. However, insight into recognition of the illness and re-labeling of psychotic phenomena did not have any significant effect on adverse clinical outcomes. Bipolar patients' insight into treatment is an independent predictor of adverse clinical outcomes. Improving insight into treatment might be a promising target for a better outcome.

2015-11-01

The aims of this study were to examine whether the association between childhood adversities and educational attainment in young adulthood can be explained by mental health problems in adolescence and whether associations and pathways differ for boys and girls. Data were used of 2,230 participants from the Tracking Adolescents' Individual Lives Survey, a Dutch prospective cohort study with a 9-year follow-up. Childhood adversities were measured at age 11 years, mental health problems (i.e., externalizing, internalizing and attention problems with Youth Self-Report) at age 16 years, and educational attainment at age 19 years. Structural equation modeling was performed to analyze the data, overall and stratified by gender. Only among boys, childhood adversities were associated with low educational attainment in young adulthood. Externalizing problems in adolescence explained 5% of the association between childhood adversities and educational attainment. Furthermore, for both boys and girls, externalizing problems in adolescence had a direct effect on educational attainment in young adulthood. Among boys, childhood adversities are associated with poorer educational outcomes of young adults. A part of this association runs via adolescent externalizing problems. The results suggest that boys, compared with girls, are less capable to cope with childhood adversities. Monitoring of exposed boys to childhood adversities is of utmost importance.

In this study, we aimed to determine the provincial population-based seroprevalence in pregnant women and to further explore the association of maternal CMV infection status and adverse pregnancy/neonatal/growth outcomes in Jiangsu, China. In this case-control study, the sera from 527 pregnant women with adverse pregnancy/neonatal outcomes and 496 mothers of healthy infants in Jiangsu Province, collected at gestation age of 15-20 weeks, were tested for anti-CMV IgG, IgM and IgG avidity. Adverse pregnancy/neonatal outcomes were identified based on pregnancy/neonatal outcomes. The overall seroprevalence of anti-CMV IgG was 98.7%, with 99.4% and 98.0% in the case and control groups, respectively (P = 0.039). The prevalence of anti-CMV IgG+/IgM+, was higher in the case group than that in the control group (3.8% vs. 1.6%, P = 0.033). Anti-CMV IgG avidity assay showed that none in the control group were primarily infected, but five (0.9%) in the case group underwent primary infection (P = 0.084); all five infants of these women presented severe adverse neonatal/growth outcomes. Exact logistic regression analysis showed that anti-CMV IgG+/IgM+ was associated with adverse pregnancy/neonatal/growth outcomes (aOR = 2.44, 95% CI 1.01-6.48, P = 0.047). Maternal low education level and prior abnormal pregnancies also were risk factors for adverse pregnancy/neonatal outcomes. In populations with very high prevalence of latent CMV infection, active maternal CMV infection during pregnancy might be a risk factor for adverse pregnancy/neonatal outcomes.

Reflection on Lessons Learned: An Analysis of the Adverse Outcomes Observed During the Hurricane Rita Evacuation.

Baker, Karen

2018-02-01

In September 2005, nearly 3.7 million people evacuated the Texas coastline in advance of Hurricane Rita's landfall, making the event the largest emergency evacuation in US history. The Rita evacuation underscored the importance of planning for domestic mass-evacuation events, as the evacuation itself led to over 100 of the at least 119 deaths attributed to the storm. In the days preceding Rita's landfall, several cascading, interrelated circumstances precipitated such adverse outcomes. This article explores the series of events leading up to the evacuation's poor outcomes, the response following Rita to amend evacuation plans, and how Texas successfully implemented these changes during later storms to achieve better outcomes.

Pregnant women and their developing fetuses are vulnerable to multiple environmental insults, including exposure to aflatoxin, a mycotoxin that may contaminate as much as 25% of the world food supply. We reviewed and integrated findings from studies of aflatoxin exposure during pregnancy and evaluated potential links to adverse pregnancy outcomes. We identified 27 studies (10 human cross-sectional studies and 17 animal studies) assessing the relationship between aflatoxin exposure and adverse birth outcomes or anemia. Findings suggest that aflatoxin exposure during pregnancy may impair fetal growth. Only one human study investigated aflatoxin exposure and prematurity, and no studies investigated its relationship with pregnancy loss, but animal studies suggest aflatoxin exposure may increase risk for prematurity and pregnancy loss. The fetus could be affected by maternal aflatoxin exposure through direct toxicity as well as indirect toxicity, via maternal systemic inflammation, impaired placental growth, or elevation of placental cytokines. The cytotoxic and systemic effects of aflatoxin could plausibly mediate maternal anemia, intrauterine growth restriction, fetal loss, and preterm birth. Given the widespread exposure to this toxin in developing countries, longitudinal studies in pregnant women are needed to provide stronger evidence for the role of aflatoxin in adverse pregnancy outcomes, and to explore biological mechanisms. Potential pathways for intervention to reduce aflatoxin exposure are urgently needed, and this might reduce the global burden of stillbirth, preterm birth, and low birthweight. PMID:28500823

The fetus could be affected by maternal aflatoxin exposure through direct toxicity as well as indirect toxicity, via maternal systemic inflammation, impaired placental growth, or elevation of placental cytokines. The cytotoxic and systemic effects of aflatoxin could plausibly mediate maternal anemia, intrauterine growth restriction, fetal loss, and preterm birth. Given the widespread exposure to this toxin in developing countries, longitudinal studies in pregnant women are needed to provide stronger evidence for the role of aflatoxin in adverse pregnancy outcomes, and to explore biological mechanisms. Potential pathways for intervention to reduce aflatoxin exposure are urgently needed, and this might reduce the global burden of stillbirth, preterm birth, and low birthweight.

Background: Existence or non-existence of adverse selection in insurance market is one of the important cases that have always been considered by insurers. Adverse selection is one of the consequences of asymmetric information. Theory of adverse selection states that high-risk individuals demand the insurance service more than low risk individuals do. Methods: The presence of adverse selection in Iran’s supplementary health insurance market is tested in this paper. The study group consists of 420 practitioner individuals aged 20 to 59. We estimate two logistic regression models in order to determine the effect of individual’s characteristics on decision to purchase health insurance coverage and loss occurrence. Using the correlation between claim occurrence and decision to purchase health insurance, the adverse selection problem in Iranian supplementary health insurance market is examined. Results: Individuals with higher level of education and income level purchase less supplementary health insurance and make fewer claims than others make and there is positive correlation between claim occurrence and decision to purchase supplementary health insurance. Conclusion: Our findings prove the evidence of the presence of adverse selection in Iranian supplementary health insurance market. PMID:23113209

OBJECTIVE To determine whether prior spontaneous (SAB) or induced (IAB) abortions, or the inter-pregnancy interval are associated with subsequent adverse pregnancy outcomes in nulliparous women. METHODS We performed a secondary analysis of data collected from nulliparous women enrolled in a completed trial of vitamins C and E or placebo for preeclampsia prevention. Adjusted odds ratios for maternal and fetal outcomes were determined for nulliparous women with prior SABs and IABs as compared to primigravid participants. RESULTS Compared with primigravidas, women with one prior SAB were at increased risk for perinatal death (OR 1.5; 95% CI 1.1–2.3) in subsequent pregnancies. Two or more SABs were associated with an increased risk for spontaneous preterm birth (OR 2.6, 95% CI 1.7–4.0), preterm PROM (OR 2.9, 95% CI 1.6–5.3) and perinatal death (OR 2.8, 95% CI 1.5–5.3). Women with one previous IAB had higher rates of spontaneous preterm birth (OR 1.4, 95% CI 1.0–1.9) and preterm PROM (OR 2.0, 95% CI 1.4–3.0). An inter-pregnancy interval less than 6 months after SAB was not associated with adverse outcomes. CONCLUSION Nulliparous women with a history of SAB or IAB, especially multiple SABs, are at increased risk for adverse pregnancy outcomes. PMID:24347257

EPA Pesticide Factsheets

The Adverse Outcome Pathway provides a construct for assembling mechanistic information at different levels of biological organization in a form designed to support regulatory decision making. In particular, it frames the link between molecular and cellular events that can be measured in high throughput toxicity testing and the organism or population-level events that are commonly relevant in defining risk. Recognizing the importance of this emerging framework, the Organisation for Economic Co-operation and Development (OECD) launched a program to support the development, documentation and consideration of AOPs by the international community in 2012 (http://www.oecd.org/chemicalsafety/testing/adverse-outcome-pathways-molecular-screening-and-toxicogenomics.htm). In 2014, a handbook (https://aopkb.org/common/AOP_Handbook.pdf) was developed to guide users in the documentation and evaluation of AOPs and their entry into an official knowledgebase. The handbook draws on longstanding experience in consideration of mechanistic data (e.g., mode of action analysis) to inform risk assessment. To further assist users, a training program was developed by members of the OECD Extended Advisory Group to teach users the basic principles of AOP development and the best practices as outlined in the OECD AOP handbook. Training sessions began in early 2015, and this course will provide training for interested SOT scientists. Following this course, all participants will be familiar w

Background and Objective. Placenta previa (PP) is a potential risk factor for obstetric hemorrhage, which is a major cause of fetomaternal morbidity and mortality in developing countries. This study aimed to determine frequency, risk factors, and adverse fetomaternal outcomes of placenta previa in Northern Tanzania. Methodology. A retrospective cohort study was conducted using maternally-linked data from Kilimanjaro Christian Medical Centre birth registry spanning 2000 to 2015. All women who gave birth to singleton infants were studied. Adjusted odds ratios (ORs) with 95% confidence intervals for risk factors and adverse fetomaternal outcomes associated with PP were estimated in multivariable logistic regression models. Result. A total of 47,686 singleton deliveries were analyzed. Of these, the frequency of PP was 0.6%. Notable significant risk factors for PP included gynecological diseases, alcohol consumption during pregnancy, malpresentation, and gravidity ≥5. Adverse maternal outcomes were postpartum haemorrhage, antepartum haemorrhage, and Caesarean delivery. PP increased odds of fetal Malpresentation and early neonatal death. Conclusion. The prevalence of PP was comparable to that found in past research. Multiple independent risk factors were identified. PP was found to have associations with several adverse fetomaternal outcomes. Early identification of women at risk of PP may help clinicians prevent such complications. PMID:28321338

Health care providers often experience traumatic events and adversity that can have negative emotional impacts on the profession and on patients. These impacts are typically multifaceted and can result from many different events, such as unanticipated outcomes, licensing board complaints, claims, and litigation. Because health care providers are exposed to diverse situations, they require adequate and timely support, imperative for provider resilience and patient safety. This study evaluated the success of an institution's second victim health care support program and best practices in responding to these traumatic experiences effectively. Twenty faculty and medical residents who utilized the support program at a large hospital system located in Central Texas from 2001 to 2012 participated in 1 of 6 focus groups. Qualitative data were collected from these groups to describe program requirements for the adequate delivery of health care adversity support and necessary program improvements. Responses were first transcribed verbatim. Each research team member analyzed data using a thematic framework approach. This approach helped to characterize traumatic experiences and to design a support system. The results revealed that (1) provider experiences are traumatic, (2) it is necessary to communicate an adverse event in a confidential and timely manner, preferably with a peer, (3) preemptive education regarding risk management and the legal process is helpful, and (4) there is a need for further support of the specific experience of a board complaint. Focus group data indicated the complexity of the emotional impact of traumatic experiences. Specific program components are needed to create best practices for providers affected by health care adversity, including support when providers face board complaints. The program's unique combination of support and education allowed us to expand upon leading national health care adversity programs. © 2016 American Society for

The relationship between adverse childhood exposures and poor health, illness, and somatic complaints at age 12 was examined. LONGSCAN (Consortium for Longitudinal Studies of Child Abuse and Neglect) tracks a group of children with variable risk for maltreatment. Of the participating child-caregiver dyads, 805 completed an interview when the child was age 4 or age 6, as well as interviews at age 8 and 12. The relationships between 8 categories of childhood adversity (psychological maltreatment, physical abuse, sexual abuse, child neglect, caregiver's substance/alcohol use, caregiver's depressive symptoms, caregiver's being treated violently, and criminal behavior in the household) and child health at age 12 were analyzed. The impact of adversity in the first 6 years of life and adversity in the second 6 years of life on child health were compared. Only 10% of the children had experienced no adversity, while more than 20% had experienced 5 or more types of childhood adversity. At age 12, 37% of the children sampled had some health complaint. Exposure to 5 or more adversities, particularly exposure in the second 6 years of life, was significantly associated with increased risks of any health complaint (odds ratio [OR] 2.24, 95% confidence interval [95% CI] 1.02-4.96), an illness requiring a doctor (OR 3.69, 95% CI 1.02-15.1), and caregivers' reports of child's somatic complaints (OR 3.37, 95% CI 1.14-1.0). There was no association between adverse exposures and self-rated poor health or self-rated somatic complaints. A comprehensive assessment of children's health should include a careful history of their past exposure to adverse conditions and maltreatment. Interventions aimed at reducing these exposures may result in better child health.

Brain injury can be identified as early as day two of life in asphyxiated newborns treated with hypothermia, when using diffusion magnetic resonance imaging (MRI). However, it remains unclear whether these diffusion changes can predict future neurodevelopment. This study aimed to determine whether abnormal early diffusion changes in newborns treated with hypothermia are associated with adverse neurodevelopmental outcome at age two years. Asphyxiated newborns treated with hypothermia were enrolled prospectively. They underwent magnetic resonance imaging (MRI) at specific time points over the first month of life, including diffusion-weighted imaging and diffusion-tensor imaging. Apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values were measured in different regions of interest. Adverse neurodevelopmental outcome was defined as cerebral palsy, global developmental delay, and/or seizure disorder around age two years. ADC and FA values were compared between the newborns developing or not developing adverse outcome. Twenty-nine asphyxiated newborns treated with hypothermia were included. Among the newborns developing adverse outcome, ADC values were significantly decreased on days two to three of life and increased around day ten of life in the thalamus, posterior limb of the internal capsule, and the lentiform nucleus. FA values decreased in the same regions around day 30 of life. These newborns also had increased ADC around day ten of life and around day 30 of life, and decreased FA around day 30 of life in the anterior and posterior white matter. Diffusion changes that were evident as early as day two of life, when the asphyxiated newborns were still treated with hypothermia, were associated with later abnormal neurodevelopmental outcome.

The association between cumulative adversity and mental health: considering dose and primary focus of adversity.

PubMed

Keinan, Giora; Shrira, Amit; Shmotkin, Dov

2012-09-01

The study addressed the dose-response model in the association of cumulative adversity with mental health. Data of 1,725 participants aged 50+ were drawn from the Israeli component of the Survey of Health, Ageing, and Retirement in Europe. Measures included an inventory of potentially traumatic events, distress (lifetime depression, depressive symptoms), and well-being (quality of life, optimism/hope). The maximal effect of cumulative trauma emerged in the contrast between 0-2 and 3+ events, where the higher number of events related to higher distress but also to higher well-being. While self-oriented adversity revealed no, or negative, association with well-being, other-oriented adversity revealed a positive association. The study suggests an experiential dose of cumulative adversity leading to a co-activation of distress and well-being. The source of this co-activation seems to be other-oriented adversity.

Purpose: To evaluate factors associated with adverse cosmesis outcome in breast cancer patients randomized to accelerated partial breast irradiation (APBI) using 3-dimensional conformal radiation therapy or whole-breast irradiation in the RAPID (Randomized Trial of Accelerated Partial Breast Irradiation) trial. Methods and Materials: Subjects were trial participants with nurse-assessed global cosmetic scores at baseline and at 3 years. Adverse cosmesis was defined as a score of fair or poor. Cosmetic deterioration was defined as any adverse change in score from baseline to 3 years. The analysis is based on data from the previously reported interim analysis. Logistic regression models were used to assessmore » the association of risk factors for these outcomes among all patients and those treated with APBI only. Results: Clinicopathologic characteristics were similar between subjects randomized to APBI (n=569) or whole-breast irradiation (n=539). For all subjects, factors associated with adverse cosmesis at 3 years were older age, central/inner tumor location, breast infection, smoking, seroma volume, breast volume, and use of APBI; factors associated with cosmetic deterioration were smoking, seroma volume, and use of APBI (P<.05). For APBI subjects, tumor location, smoking, age, and seroma volume were associated with adverse cosmesis (P<.05), and smoking was associated with cosmetic deterioration (P=.02). An independent association between the V95/whole-breast volume ratio and adverse cosmesis (P=.28) or cosmetic deterioration (P=.07) was not detected. On further exploration a V95/whole-breast volume ratio <0.15 was associated with a lower risk of cosmetic deterioration (p=.04), but this accounted for only 11% of patients. Conclusion: In the RAPID trial, a number of patient tumor and treatment-related factors, including the use of APBI, were associated with adverse cosmesis and cosmetic deterioration. For patients treated with APBI alone, the high

 The objective of this study was to describe the relationship between early pregnancy body mass index (BMI) and maternal, perinatal, and neonatal outcomes in rural India and Pakistan.  In a prospective, population-based pregnancy registry implemented in communities in Thatta, Pakistan and Nagpur and Belagavi, India, we obtained women's BMI prior to 12 weeks' gestation (categorized as underweight, normal, overweight, and obese following World Health Organization criteria). Outcomes were assessed 42 days postpartum.  The proportion of women with an adverse maternal outcome increased with increasing maternal BMI. Less than one-third of nonoverweight/nonobese women, 47.2% of overweight women, and 56.0% of obese women experienced an adverse maternal outcome. After controlling for site, maternal age and parity, risks of hypertensive disease/severe preeclampsia/eclampsia, cesarean/assisted delivery, and antibiotic use were higher among women with higher BMIs. Overweight women also had significantly higher risk of perinatal and early neonatal mortality compared with underweight/normal BMI women. Overweight women had a significantly higher perinatal mortality rate.  High BMI in early pregnancy was associated with increased risk of adverse maternal, perinatal, and neonatal outcomes in rural India and Pakistan. These findings present an opportunity to inform efforts for women to optimize weight prior to conception to improve pregnancy outcomes.

Objectives. We explored the association of sexual orientation with poor adult health outcomes before and after adjustment for exposure to adverse childhood experiences (ACEs). Methods. Data were from the 2012 North Carolina, 2011 Washington, and 2011 and 2012 Wisconsin Behavioral Risk Factor Surveillance System (BRFSS) surveys regarding health risks, perceived poor health, and chronic conditions by sexual orientation and 8 categories of ACEs. There were 711 lesbian, gay, and bisexual (LGB) respondents and 29 690 heterosexual respondents. Results. LGB individuals had a higher prevalence of all ACEs than heterosexuals, with odds ratios ranging from 1.4 to 3.1. After adjustment for cumulative exposure to ACEs, sexual orientation was no longer associated with poor physical health, current smoking, and binge drinking. Associations with poor mental health, activity limitation, HIV risk behaviors, current asthma, depression, and disability remained, but were attenuated. Conclusions. The higher prevalence of ACEs among LGB individuals may account for some of their excess risk for poor adult health outcomes. PMID:26691127

Adverse effects of public health interventions: a conceptual framework.

Public health interventions may have a range of adverse effects. However, there is limited guidance as to how evaluations should address the possibility of adverse effects. This discussion paper briefly presents a framework for thinking about the potential harms of public health interventions, focusing on the following categories: direct harms; psychological harms; equity harms; group and social harms; and opportunity harms. We conclude that the possibility of adverse effects needs to be taken into account by those implementing and evaluating interventions, and requires a broad perspective on the potential impacts of public health strategies.

Complications related to preterm birth (PTB) and low birth weight (LBW) are leading causes of infant morbidity and mortality. Prenatal depression is a hypothesized psychosocial risk factor for both birth outcomes. The purpose of this systematic review was to examine evidence published between 1977 and 2013 on prenatal depression and risks of these primary adverse birth outcomes. A systematic search of the PUBMED and PsycINFO databases was conducted to identify studies testing the associations between prenatal depressive symptoms, or diagnoses of depression, and risk of PTB or LBW. We systematically selected 50 published reports on PTB and length of gestation, and 33 reports on LBW and BW. Results were reviewed by two independent reviewers and we evaluated the quality of the evidence with an established systematic review method, the Newcastle Ottawa Scale. We then undertook a narrative synthesis of the results following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Less than a quarter of 50 published reports found that prenatal depression was significantly associated with PTB or gestational age. In contrast, slightly more than half of the 33 reports found that prenatal depression was associated with LBW or BW. When weighing methodological features, we determined that the effects of prenatal depression on LBW are more consistent than effects on length of gestation or PTB. Although the evidence may not be strong enough to support routine depression screening for risk of adverse outcomes, screening to enable detection and timely treatment to reduce risk of postpartum depression is warranted. Further rigorous research on prenatal depression and adverse birth outcomes is needed. PMID:25452215

Purpose: Although the likelihood of radiation-related adverse events influences treatment decisions regarding radiation therapy after prostatectomy for eligible patients, the data available to inform decisions are limited. This study was designed to evaluate the genitourinary, gastrointestinal, and sexual adverse events associated with postprostatectomy radiation therapy and to assess the influence of radiation timing on the risk of adverse events. Methods: The Regione Emilia-Romagna Italian Longitudinal Health Care Utilization Database was queried to identify a cohort of men who received radical prostatectomy for prostate cancer during 2003 to 2009, including patients who received postprostatectomy radiation therapy. Patients with prior radiation therapymore » were excluded. Outcome measures were genitourinary, gastrointestinal, and sexual adverse events after prostatectomy. Rates of adverse events were compared between the cohorts who did and did not receive postoperative radiation therapy. Multivariable Cox proportional hazards models were developed for each class of adverse events, including models with radiation therapy as a time-varying covariate. Results: A total of 9876 men were included in the analyses: 2176 (22%) who received radiation therapy and 7700 (78%) treated with prostatectomy alone. In multivariable Cox proportional hazards models, the additional exposure to radiation therapy after prostatectomy was associated with increased rates of gastrointestinal (rate ratio [RR] 1.81; 95% confidence interval [CI] 1.44-2.27; P<.001) and urinary nonincontinence events (RR 1.83; 95% CI 1.83-2.80; P<.001) but not urinary incontinence events or erectile dysfunction. The addition of the time from prostatectomy to radiation therapy interaction term was not significant for any of the adverse event outcomes (P>.1 for all outcomes). Conclusion: Radiation therapy after prostatectomy is associated with an increase in gastrointestinal and genitourinary adverse events

Childhood Adversities and Adult Cardiometabolic Health: Does the Quantity, Timing, and Type of Adversity Matter?

2015-01-01

Objective Adverse events in childhood can indelibly influence adult health. While evidence for this association has mounted, a fundamental set of questions about how to operationalize adverse events has been understudied. Method We used data from the National Survey of Midlife Development in the United States to examine how quantity, timing, and types of adverse events in childhood are associated with adult cardiometabolic health. Results The best-fitting specification of quantity of events was a linear measure reflecting a dose–response relationship. Timing of event mattered less than repeated exposure to events. Regarding the type of event, academic interruptions and sexual/physical abuse were most important. Adverse childhood events elevated the risk of diabetes and obesity similarly for men and women but had a greater impact on women’s risk of heart disease. Discussion Findings demonstrate the insights that can be gleaned about the early-life origins of adult health by examining operationalization of childhood exposures. PMID:25903978

Ionotropic GABA receptor antagonism-induced adverse outcome pathways for potential neurotoxicity biomarkers.

PubMed

Gong, Ping; Hong, Huixiao; Perkins, Edward J

2015-01-01

Antagonism of ionotropic GABA receptors (iGABARs) can occur at three distinct types of receptor binding sites causing chemically induced epileptic seizures. Here we review three adverse outcome pathways, each characterized by a specific molecular initiating event where an antagonist competitively binds to active sites, negatively modulates allosteric sites or noncompetitively blocks ion channel on the iGABAR. This leads to decreased chloride conductance, followed by depolarization of affected neurons, epilepsy-related death and ultimately decreased population. Supporting evidence for causal linkages from the molecular to population levels is presented and differential sensitivity to iGABAR antagonists in different GABA receptors and organisms discussed. Adverse outcome pathways are poised to become important tools for linking mechanism-based biomarkers to regulated outcomes in next-generation risk assessment.

The aim of the article is to determine whether prior spontaneous abortion (SAB) or induced abortion (IAB), or the interpregnancy interval are associated with subsequent adverse pregnancy outcomes in nulliparous women. We performed a secondary analysis of data collected from nulliparous women enrolled in a completed trial of vitamins C and E or placebo for preeclampsia prevention. Adjusted odds ratios (ORs) for maternal and fetal outcomes were determined for nulliparous women with prior SABs and IABs as compared with primigravid participants. Compared with primigravidas, women with one prior SAB were at increased risk for perinatal death (adj. OR, 1.5; 95% CI, 1.1-2.3) in subsequent pregnancies. Two or more SABs were associated with an increased risk for spontaneous preterm birth (PTB) (adj. OR, 2.6, 95% CI, 1.7-4.0), preterm premature rupture of membranes (PROM) (adj. OR, 2.9; 95% CI, 1.6-5.3), and perinatal death (adj. OR, 2.8; 95% CI, 1.5-5.3). Women with one previous IAB had higher rates of spontaneous PTB (adj. OR, 1.4; 95% CI, 1.0-1.9) and preterm PROM (OR, 2.0; 95% CI, 1.4-3.0). An interpregnancy interval less than 6 months after SAB was not associated with adverse outcomes. Nulliparous women with a history of SAB or IAB, especially multiple SABs, are at increased risk for adverse pregnancy outcomes. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

To assess and compare multiple measurements of socioeconomic position (SEP) in order to determine the relationship with adverse perinatal outcomes across various contexts. A birth registry, the Nova Scotia Atlee Perinatal Database, was confidentially linked to income tax and related information for the year in which delivery occurred. Multiple logistic regression was used to examine odds ratios between multiple indicators of SEP and multiple adverse perinatal outcomes in 117734 singleton births between 1988 and 2003. Models for after tax family income were also adjusted for neighborhood deprivation to gauge the relative magnitude of effects related to SEP at both levels. Effects of SEP were stratified by single- versus multiple-parent family composition, and by urban versus rural location of residence. The risk of small for gestational age and spontaneous preterm birth was higher across all the indicators of lower SEP, while risk for large for gestational age was lower across indicators of lower SEP. Higher risk of postneonatal death was demonstrated for several measures of lower SEP. Higher material deprivation in the neighborhood of residence was associated with increased risk for perinatal death, small for gestational age birth, and iatrogenic and spontaneous preterm birth. Family composition and urbanicity were shown to modify the association between income and some perinatal outcomes. This study highlights the importance of understanding the definitions of SEP and the mechanisms that lead to the association between income and poor perinatal outcomes, and broadening the types of SEP measures used in some cases.

The adverse effects of International Monetary Fund programs on the health and education workforce.

Decades of underinvestment in public sectors and in teachers and health workers have adversely affected the health and educational outcomes of women. This is partly explained by a general lack of resources. However, the amount a country can spend on social sectors, including teachers and health workers, is also determined by its macroeconomic framework, which is set in agreement with the International Monetary Fund. There is now ample evidence of how IMF-imposed wage ceilings have constrained the ability of governments to hire adequate numbers of trained professionals and increase investment in social sectors. Though the IMF has recently removed wage ceilings from its basket of conditions, little change has taken place to ensure that women are better supported by macroeconomic policies or, at the least, are less adversely affected. Thus far, the IMF's neoliberal policies have either ignored gender concerns or instrumentalized equity, health, and education to support economic development. Unless macroeconomic policies are more flexible and deliberately take into account the different needs of women and men, social outcomes will continue to be poor and inequitable. Governments must pursue alternative, feminist policies that put the goals of social equity at the center of macroeconomic policy. These policies can facilitate increased investment in education and health care, which are vital measures for achieving gender equality and providing both women and men with the skills and training needed to soften the impact of the current economic crisis.

Gestational diabetes mellitus (GDM) is a common disease in pregnancy causing maternal and fetal complications. To prevent these adverse outcomes, optimal screening and diagnostic criteria must be adequate, timely, and efficient. This study suggests a novel approach that is practical, efficient, and patient- and clinician-friendly in predicting adverse outcomes of GDM. The authors conducted a retrospective cohort study via medical record review of patients admitted between March 2001 and April 2013 at the Severance Hospital, Seoul, South Korea. Patients diagnosed by a conventional 2-step method were evaluated according to the presence of adverse outcomes (neonatal hypoglycemia, hyperbilirubinemia, and hyperinsulinemia; admission to the neonatal intensive care unit; large for gestational age; gestational insulin therapy; and gestational hypertension). Of 802 women who had an abnormal 50-g, 1-hour glucose challenge test, 306 were diagnosed with GDM and 496 did not have GDM (false-positive group). In the GDM group, 218 women (71.2%) had adverse outcomes. In contrast, 240 women (48.4%) in the false-positive group had adverse outcomes. Women with adverse outcomes had a significantly higher body mass index (BMI) at entry (P = 0.03) and fasting blood glucose (FBG) (P = 0.03). Our logistic regression model derived from 2 variables, BMI at entry and FBG, predicted GDM adverse outcome with an area under the curve of 0.642, accuracy of 61.3%, sensitivity of 57.2%, and specificity of 66.9% compared with the conventional 2-step method with an area under the curve of 0.610, accuracy of 59.1%, sensitivity of 47.6%, and specificity of 74.4%. Our model performed better in predicting GDM adverse outcomes than the conventional 2-step method using only BMI at entry and FBG. Moreover, our model represents a practical, inexpensive, efficient, reproducible, easy, and patient- and clinician-friendly approach.

Epidemiologists and medical researchers often employ an allostatic load model that focuses on environmental and lifestyle factors, together with biological vulnerabilities, to explain the deterioration of human physiological systems and chronic degenerative disease. Although this perspective has informed medicine and public health, it is agnostic toward the functional significance of pathophysiology and health deterioration. Drawing on Life History (LH) theory, the current paper reviews the literature on disadvantaged families to serve as a conceptual model of stress-health relationships in which the allocation of reproductive effort is instantiated in the LH strategies of individuals and reflects the bioenergetic and material resource tradeoffs . We propose that researchers interested in health disparities reframe chronic degenerative diseases as outcomes resulting from strategic calibration of physiological systems to best adapt, survive, and reproduce in response to demands of specific developmental contexts. These effects of adversity on later-age degenerative disease are mediated, in part, by socioemotional and cognitive mechanisms expressed in different life history strategies.

Few studies have assessed the associations between residential proximity to power plants and adverse birth outcomes including preterm delivery (PTD), very preterm delivery (VPTD), and term low birth weight (LBW). We geocoded 423,719 singleton Florida births born from 2004 to 2005 and all active power plants and determined residential proximity to the nearest power plant for each birth. Prenatal exposure to particulate matter less than 2.5 µm in diameter for women living near different types of power plants was also determined by using National Environmental Public Health Tracking Network data. Logistic regression models were used to test the hypothesized associations. Women who lived closer to coal and solid waste power plants were exposed to higher levels of particulate matter less than 2.5 µm in diameter compared with other types. We observed a 1.8% (95% confidence interval (CI): 1.3, 2.3) increased odds for PTD, 2.2% (95% CI: 1.0, 3.4) for VPTD, and 1.1% (95% CI: 0.2, 2.0) for term LBW for each 5 km closer to any power plant. When stratifying by different fuel type, we found that only solid waste had an association with term LBW, whereas oil, gas, and solid waste all had an association with PTD and VPTD. Results were consistent when exposure was categorized by number of power plants. Our study found evidence of increasing odds of adverse birth outcomes among infants born to pregnant women living closer to power plants. More research is warranted to better understand the causal relationship. PMID:26121989

To study the factors associated with an adverse pregnancy outcome in women with systemic lupus erythematosus (SLE). SLE women from LUMINA of Hispanic, African American and Caucasian ethnicity were studied. Adverse pregnancy outcome was a miscarriage or abortion (<20 weeks), a stillbirth (> or = 20) and/or a moderate to severe preterm-baby (<34 weeks); good outcome was either a mild preterm-baby (> or = 34 weeks) or a full-term baby [C-section or vaginal delivery (38-42 weeks)]. Pregnancies occurring after SLE diagnosis (TD) were included; pregnancy outcome was the unit of analyses. The relationship between selected variables and pregnancy outcomes was examined by univariable and multivariable analyses. Adverse outcomes occurred in 63.7% of 102 pregnancies. In the univariable analyses, Texan Hispanic and African American ethnicities, fewer years of education, higher number of ACR criteria, renal involvement, glucocorticoid exposure and the maximum dose of glucocorticoids used prior to the pregnancy outcome were associated with an adverse pregnancy outcome. Renal involvement was independently associated with an adverse pregnancy outcome [Odds ratio (OR)=5.219 (95% Confidence Interval (CI) 1.416-19.239, p=0.0131] as were the maximum dose of glucocorticoids used prior to the pregnancy outcome (OR=1.028; CI:1.002-1.054; p=0.0315) and fewer years of education (OR=1.204; CI:1.006-1.472; p=0.0437). Ethnicity was not retained in the multivariable model. Renal involvement, the maximum dose of glucocorticoids used prior to pregnancy and fewer years of education were associated with adverse pregnancy outcomes. These data have implications for the management of women with lupus planning to become pregnant.

Advancing the Adverse Outcome Pathway Framework - an ...

The ability of scientists to conduct whole organism toxicity tests to understand chemical safety has been significantly outpaced by the rapid synthesis of new chemicals. Therefore, to increase efficiencies in chemical risk assessment, scientists are turning to mechanistic-based studies, making greater use of in vitro and in silico methods, to screen for potential environmental and human health hazards. A framework that has gained traction for capturing available knowledge describing the linkage between mechanistic data and apical toxicity endpoints, required for regulatory assessments, is the adverse outcome pathway (AOP). A number of international activities have focused on AOP development and plausible applications to regulatory decision-making. These interactions have prompted dialog between research scientists and regulatory communities to consider how best to use the AOP framework in risk assessment. While expert-facilitated discussions have been instrumental in moving the science of AOPs forward, it was recognized that a survey of the broader scientific community would aid in identifying shortcomings and guiding future initiatives for the AOP framework. To that end, a ?‘Horizon Scanning’ exercise was conducted to solicit questions from the global scientific and regulatory communities concerning the challenges or limitations that must be addressed to realize the full potential of the AOP framework in research and regulatory decision making.

Previous analyses utilizing birth certificate data have shown environmental factors such as racial residential segregation may contribute to disparities in adverse pregnancy outcomes. However, birth certificate data are ill equipped to reliably differentiate among small for gestational age, spontaneous preterm birth, and medically indicated preterm birth. We sought to utilize data from electronic medical records to determine whether residential segregation among Black women is associated with an increased risk of adverse pregnancy outcomes. The study population was composed of 4770 non-Hispanic Black women who delivered during the years 2009 through 2013 at a single urban medical center. Addresses were geocoded at the level of census tract, and this tract was used to determine the degree of residential segregation for an individual's neighborhood. Residential segregation was measured using the Gi* statistic, a z-score that measures the extent to which the neighborhood racial composition deviates from the composition of the larger surrounding area. The Gi* statistic z-scores were categorized as follows: low (z < 0), medium (z = 0-1.96), and high (z > 1.96). Adverse pregnancy outcomes included overall preterm birth, spontaneous preterm birth, medically indicated preterm birth, and small for gestational age. Hierarchical logistic regression models accounting for clustering by census tract and repeated births among mothers were used to estimate odds ratios of adverse pregnancy outcomes associated with segregation. In high segregation areas, the prevalence of overall preterm birth was significantly higher than that in low segregation areas (15.5% vs 10.7%, respectively; P < .001). Likewise, the prevalence of spontaneous preterm birth and medically indicated preterm birth were higher in high (9.5% and 6.0%) vs low (6.2% and 4.6%) segregation neighborhoods (P < .001 and P = .046, respectively).

In total, 50 different exposure metrics were available for the analyses. The exposure of primary interest was the mean of the entire pregnancy period for each mother. For the health analyses, controls were randomly selected from the source population. PTB controls were matched on conception year. Term LBW, preeclampsia, and GDM were analyzed using generalized additive mixed models with inclusion of a random effect per hospital. PTB analyses were conducted using conditional logistic regression, with no adjustment for hospital. The main results— adjusted for race and education as categorical variables and adjusted for maternal age and median household income at the census-block level—were derived from single-pollutant models. In its independent review of the study, the HEI Health Review Committee concluded that Wu and colleagues had conducted a comprehensive nested case–control study of air pollution and adverse birth and pregnancy outcomes. The very large data set and the extensive exposure assessment were strengths of the study. The study documented associations between increases in various air pollution metrics and increased risks of PTB, whereas the evidence was weaker overall for term LBW; in addition, decreases in many air pollution metrics were associated with an increased risk of preeclampsia and GDM, an unexpected result. The investigators suggested that underreporting in the registry data, especially in lower-SES groups, might have caused the many negative associations found for preeclampsia and GDM. In addition, poor geocoding was listed as a potential explanation, affecting in particular

Background: Trends in male reproductive health have been reported for increased rates of testicular germ cell tumors, low semen quality, cryptorchidism, and hypospadias, which have been associated with prenatal environmental chemical exposure based on human and animal studies. Objective: In the present study we aimed to identify significant correlations between environmental chemicals, molecular targets, and adverse outcomes across a broad chemical landscape with emphasis on developmental toxicity of the male reproductive system. Methods: We used U.S. EPA’s animal study database (ToxRefDB) and a comprehensive literature analysis to identify 774 chemicals that have been evaluated for adverse effects on male reproductive parameters, and then used U.S. EPA’s in vitro high-throughput screening (HTS) database (ToxCastDB) to profile their bioactivity across approximately 800 molecular and cellular features. Results: A phenotypic hierarchy of testicular atrophy, sperm effects, tumors, and malformations, a composite resembling the human testicular dysgenesis syndrome (TDS) hypothesis, was observed in 281 chemicals. A subset of 54 chemicals with male developmental consequences had in vitro bioactivity on molecular targets that could be condensed into 156 gene annotations in a bipartite network. Conclusion: Computational modeling of available in vivo and in vitro data for chemicals that produce adverse effects on male reproductive end points revealed a phenotypic hierarchy across animal studies consistent with the human TDS hypothesis. We confirmed the known role of estrogen and androgen signaling pathways in rodent TDS, and importantly, broadened the list of molecular targets to include retinoic acid signaling, vascular remodeling proteins, G-protein coupled receptors (GPCRs), and cytochrome P450s.

The authors sought to determine whether pregnancies in adolescents following an abortion of pregnancy is associated with an elevated risk for adverse perinatal outcomes. In a cohort study of all adolescent (younger than 18 years) deliveries over a 4-year period at 1 institution, we compared nulliparous women with a history of a prior abortion (cases) to those without a spontaneous loss or abortion of pregnancy (referent) for adverse perinatal outcomes, including preterm birth and fetal growth restriction. Of the 654 included nulliparous adolescent deliveries, 102 (16%) had an abortion before the index pregnancy. Compared with the referent group, adolescents with a history of a abortion were older (17.8 ± 0.8 vs 16.7 ± 1.2 years, P = .0001), enrolled earlier for prenatal care (14.4 ± 5.6 vs 17.2 ± 7.6 weeks, P = .0004), along with a higher incidence of African American race (95% vs 88%, P = .05). The groups did not differ with respect to other maternal demographics. Perinatal outcomes, including spontaneous preterm birth, abnormal placentation, birth weight, and gestational age at delivery, did not differ between the 2 groups. Compared with adolescent women who had just delivered and did not have a prior abortion, women who had just delivered and had a previous abortion were more likely to be older at the age of their first pregnancy and more likely to initiate early prenatal care. Thus, having a prior abortion may improve the health of a pregnancy though adverse outcomes do not differ between the 2 groups.

To investigate the association between learning climate and adverse perinatal and maternal outcomes in obstetrics-gynecology departments. The authors analyzed 23,629 births and 103 learning climate evaluations from 16 nontertiary obstetrics-gynecology departments in the Netherlands in 2013. Multilevel logistic regressions were used to calculate the odds of adverse perinatal and maternal outcomes, by learning climate score tertile, adjusting for maternal and department characteristics. Adverse perinatal outcomes included fetal or early neonatal mortality, five-minute Apgar score < 7, or neonatal intensive care unit admission for ≥ 24 hours. Adverse maternal outcomes included postpartum hemorrhage and/or transfusion, death, uterine rupture, or third- or fourth-degree perineal laceration. Bias analyses were conducted to quantify the sensitivity of the results to uncontrolled confounding and selection bias. Learning climate scores were significantly associated with increased odds of adverse perinatal outcomes (aOR 2.06, 95% CI 1.14-3.72). Compared with the lowest tertile, departments in the middle tertile had 46% greater odds of adverse perinatal outcomes (aOR 1.46, 95% CI 1.09-1.94); departments in the highest tertile had 69% greater odds (aOR 1.69, 95% CI 1.24-2.30). Learning climate was not associated with adverse maternal outcomes (middle vs. lowest tertile: OR 1.04, 95% CI 0.93-1.16; highest vs. lowest tertile: OR 0.98, 95% CI 0.88-1.10). Learning climate was associated with significantly increased odds of adverse perinatal, but not maternal, outcomes. Research in similar clinical contexts is needed to replicate these findings and explore potential mechanisms behind these associations.

An adverse outcome pathway (AOP) description linking inhibition of aromatase (cytochrome P450 [cyp] 19) to reproductive dysfunction was reviewed for scientific and technical quality and endorsed by the OECD. An intended application of the AOP framework is to support the use of mechanistic or pathway-based data to infer or predict chemical hazards and apical adverse outcomes. As part of this work, ToxCast high throughput screening data were used to identify a chemicals’ ability to inhibit aromatase activity in vitro. Twenty-four hour in vivo exposures, focused on effects on production and circulating concentrations of 17β-estradiol (E2), key events in the AOP, were conducted to verify in vivo activity. Based on these results, imazalil was selected as a case study chemical to test an AOP-based hazard prediction. A computational model of the fish hypothalamic-pituitary-gonadal-liver axis and a statistically-based model of oocyte growth dynamics were used to predict impacts of different concentrations of imazalil on multiple key events along the AOP, assuming continuous exposure for 21 d. Results of the model simulations were used to select test concentrations and design a fathead minnow reproduction study in which fish were exposed to 20, 60, or 200 µg imazalil/L for durations of 2.5, 10, or 21d. Within 60 h of exposure, female fathead minnows showed significant reductions in ex vivo production of E2, circulating E2 concentrations, and significant increases in

Practical approaches to adverse outcome pathway (AOP) ...

EPA Pesticide Factsheets

Adverse Outcome Pathways (AOPs) describe toxicant effects as a sequential chain of causally linked events beginning with a molecular perturbation and culminating in an adverse outcome at an individual or population level. Strategies for developing AOPs are still evolving and depend largely on the intended use or motivation for development. Four ecological AOP case studies, which were developed for different purposes, are described herein. In each situation, creation of the AOP began in a manner determined by the initial motivation for its creation, and expanded either to include additional components of the pathway, or to address the domains of applicability in terms of chemical initiators, susceptible species, life stages, etc. From these case studies, some general strategies can be gleaned which a developer may find useful for supporting an existing AOP or creating a new one. Several web-based tools which can aid in AOP assembly, as well as evaluation of weight of evidence for scientific robustness of AOP components are highlighted. The need for AOP development and greater population of AOPs in the online knowledgebase has been widely recognized (e.g., OECD Project 1.29, Knapen et al 2015, Escher et al 2016; Groh et al 2015), but currently there are few AOP developers. To promote broader development of AOPs, and the inclusion of potential developers across various types of institutes and fields of study, this manuscript outlines strategies for initiating

The Sloane Project is the largest prospective audit of ductal carcinoma in situ (DCIS) worldwide, with over 12,000 patients registered between 2003 and 2012, accounting for 50% of screen-detected DCIS diagnosed in the United Kingdom (UK) over the period of accrual. Complete multidisciplinary data from 8313 patients with screen-detected DCIS were analysed for surgical outcome in relation to key radiological and pathological parameters for the cohort and also by hospital of treatment. Adverse surgical outcomes were defined as either failed breast conservation surgery (BCS) or mastectomy for small lesions (<20mm) (MFSL). Inter-hospital variation was analysed by grouping hospitals into high, medium and low frequency subgroups for these two adverse outcomes. Patients with failed BCS or MFSL together accounted for 49% of all mastectomies. Of 6633 patients embarking on BCS, 799 (12.0%) required mastectomy. MFSL accounted for 510 (21%) of 2479 mastectomy patients. Failed BCS was associated with significant radiological under-estimation of disease extent and MFSL significant radiological over-estimation of disease extent. There was considerable and significant inter-hospital variation in failed BCS (range 3-32%) and MFSL (0-60%) of a hospital's BCS/mastectomy workload respectively. Conversely, there were no differences between the key radiological and pathological parameters in high, medium and low frequency adverse-outcome hospitals. This evidence suggests significant practice variation, not patient factors, is responsible for these adverse surgical outcomes in screen-detected DCIS. The Sloane Project provides an evidence base for future practice benchmarking. Copyright © 2014 Elsevier Ltd. All rights reserved.

This study assessed the long-term health impact of environmental exposures associated with open pit burning in deployed US service members. Two hundred individuals deployed to Balad, Iraq, and Bagram, Afghanistan, with known exposure to open pits, were matched to 200 non-deployed service members. Both cohorts were observed for adverse health outcomes after returning from deployment. Slight increased risks were observed for respiratory diseases in the Bagram cohort (adj RR: 1.259), and for cardiovascular disease in the Balad cohort (adj RR: 1.072), but the findings were not significant. The combined deployed cohort showed lower risks for adverse health outcomes, suggesting a healthy deployer effect. In conclusion, this study did not find significantly increased risks for selected health outcomes after burn pit exposure during deployment among two deployed cohorts compared with a non-deployed cohort.

, malnutrition, pressure sore risk, and self-rated health. None of these risk factors significantly increased the risk of adverse outcome (LR+ range = 0.78 to 2.84). The absence of dependency reduces the risk of 1-year mortality (LR- = 0.27) and nursing home placement (LR- = 0.27). Five constructs of frailty were evaluated, but none increased or decreased the risk of adverse outcome. Three instruments were evaluated in the meta-analysis: Identification of Seniors at Risk, Triage Risk Screening Tool, and Variables Indicative of Placement Risk. None of these instruments significantly increased (LR+ range for various outcomes = 0.98 to 1.40) or decreased (LR- range = 0.53 to 1.11) the risk of adverse outcomes. The test threshold for 3-month functional decline based on the most accurate instrument was 42%, and the treatment threshold was 61%. Risk stratification of geriatric adults following ED care is limited by the lack of pragmatic, accurate, and reliable instruments. Although absence of dependency reduces the risk of 1-year mortality, no individual risk factor, frailty construct, or risk assessment instrument accurately predicts risk of adverse outcomes in older ED patients. Existing instruments designed to risk stratify older ED patients do not accurately distinguish high- or low-risk subsets. Clinicians, educators, and policy-makers should not use these instruments as valid predictors of post-ED adverse outcomes. Future research to derive and validate feasible ED instruments to distinguish vulnerable elders should employ published decision instrument methods and examine the contributions of alternative variables, such as health literacy and dementia, which often remain clinically occult. © 2014 by the Society for Academic Emergency Medicine.

Childhood adversity negatively impacts the biological development of children and has been linked to poor health outcomes across the life course. The purpose of this literature review is to explore and evaluate the effectiveness of interventions that have addressed an array of biological markers and physical health outcomes in children and adolescents affected by adversity. PubMed, CINAHL, PsychInfo, Sociological Abstracts databases and additional sources (Cochrane, WHO, NIH trial registries) were searched for English language studies published between January 2007 and September 2017. Articles with a childhood adversity exposure, biological health outcome, and evaluation of intervention using a randomized controlled trial study design were selected. The resulting 40 intervention studies addressed cortisol outcomes (n = 20) and a range of neurological, epigenetic, immune, and other outcomes (n = 22). Across institutional, foster care, and community settings, intervention programs demonstrated success overall for improving or normalizing morning and diurnal cortisol levels, and ameliorating the impacts of adversity on brain development, epigenetic regulation, and additional outcomes in children. Factors such as earlier timing of intervention, high quality and nurturant parenting traits, and greater intervention engagement played a role in intervention success. This study underlines progress and promise in addressing the health impacts of adversity in children. Ongoing research efforts should collect baseline data, improve retention, replicate studies in additional samples and settings, and evaluate additional variables, resilience factors, mediators, and long-term implications of results. Clinicians should integrate lessons from the intervention sciences for preventing and treating the health effects of adversity in children and adolescents. Copyright © 2018 The Authors.

In The Netherlands, health professionals have created a doctor-driven standardised system to report and analyse adverse outcomes (AO). The aim is to improve healthcare by learning from past experiences. The key elements of this system are (1) an unequivocal definition of an adverse outcome, (2) appropriate contextual information and (3) a three-dimensional hierarchical classification system. First, to assess whether routine doctor-driven AO reporting is feasible. Second, to investigate how doctors can learn from AO reporting and analysis to improve the quality of care. Feasibility was assessed by how well doctors reported AO in the surgical department of a Dutch university hospital over a period of 9 years. AO incidence was analysed per patient subgroup and over time, in a time-trend analysis of three equal 3-year periods. AO were analysed case by case and statistically, to learn lessons from past events. In 19,907 surgical admissions, 9189 AOs were reported: one or more AO in 18.2% of admissions. On average, 55 lessons were learnt each year (in 4.3% of AO). More AO were reported in P3 than P1 (OR 1.39 (1.23-1.57)). Although minor AO increased, fatal AO decreased over time (OR 0.59 (0.45-0.77)). Doctor-driven AO reporting is shown to be feasible. Lessons can be learnt from case-by-case analyses of individual AO, as well as by statistical analysis of AO groups and subgroups (illustrated by time-trend analysis), thus contributing to the improvement of the quality of care. Moreover, by standardising AO reporting, data can be compared across departments or hospitals, to generate (confidential) mirror information for professionals cooperating in a peer-review setting.

Normal amniotic fluid predicts normal placental function, fetal growth and fetal well-being. To determine adverse pregnancy outcomes in borderline amniotic fluid index (AFI). Pregnant women (37-40 wks) with diagnosis of borderline AFI between December 2012 and August 2014 were identified. Antepartum, intrapartum and neonatal data were collected and compared with those of pregnant women with normal AFI. An AFI less than 8 and more than 5 cm was defined for borderline AFI. Pregnancy outcomes included Cesarean section for non-reassuring fetal heart rate, meconium stained amniotic fluid, 5-min Apgar score <7, low birth weight, umbilical cord blood pH at term and NICU admission. Gestational age at delivery in pregnancies with borderline AFI was significantly lower than normal AFI. Cesarean section rate for non-reassuring fetal heart rate in women of borderline AFI was significantly higher and there was an increased incidence of birth weight less than 10 th percentile for gestation age in borderline AFI group. Incidence of low Apgar score and low umbilical artery pH in pregnancies with borderline AFI was significantly higher than women with normal AFI. There were no significant difference in the rate of NICU admission and meconium staining in both groups. There are significant differences for adverse pregnancy outcomes , such as Cesarean section due to non-reassuring fetal heart rate, birth weight less than 10 th percentile for gestation age, low 5 min Apgar score and low umbilical artery pH between pregnancies with borderline and normal AFI.

Abstract Objective To perform a systematic review and meta-analysis of reported estimates of adverse pregnancy outcomes among untreated women with syphilis and women without syphilis. Methods PubMed, EMBASE and Cochrane Libraries were searched for literature assessing adverse pregnancy outcomes among untreated women with seroreactivity for Treponema pallidum infection and non-seroreactive women. Adverse pregnancy outcomes were fetal loss or stillbirth, neonatal death, prematurity or low birth weight, clinical evidence of syphilis and infant death. Random-effects meta-analyses were used to calculate pooled estimates of adverse pregnancy outcomes and, where appropriate, heterogeneity was explored in group-specific analyses. Findings Of the 3258 citations identified, only six, all case-control studies, were included in the analysis. Pooled estimates showed that among untreated pregnant women with syphilis, fetal loss and stillbirth were 21% more frequent, neonatal deaths were 9.3% more frequent and prematurity or low birth weight were 5.8% more frequent than among women without syphilis. Of the infants of mothers with untreated syphilis, 15% had clinical evidence of congenital syphilis. The single study that estimated infant death showed a 10% higher frequency among infants of mothers with syphilis. Substantial heterogeneity was found across studies in the estimates of all adverse outcomes for both women with syphilis (66.5% [95% confidence interval, CI: 58.0–74.1]; I2 = 91.8%; P < 0.001) and women without syphilis (14.3% [95% CI: 11.8–17.2]; I2 = 95.9%; P < 0.001). Conclusion Untreated maternal syphilis is associated with adverse pregnancy outcomes. These findings can inform policy decisions on resource allocation for the detection of syphilis and its timely treatment in pregnant women. PMID:23476094

Low levels of maternal serum pregnancy associated plasma protein-A (PAPP-A) have been linked to chromosome anomalies such as trisomy 21, 13 and 18, triploidy and sex chromosome aneuploidy. Low levels of PAPP-A have also been implicated in spontaneous miscarriage. The purpose of this study was to evaluate whether low levels of first trimester PAPP-A are predictive of other adverse pregnancy outcomes. The study included patients with singleton pregnancies who underwent combined first trimester screening using nuchal translucency (NT) and maternal serum free beta-human chorionic gonadotrophin (free beta-hCG) and PAPP-A at 10-13 weeks' gestation. Patients with chromosome aberrations or fetal anomalies were excluded. Serum marker levels were expressed as gestational age-specific multiples of the median (MoMs). The incidences of various adverse pregnancy outcomes (spontaneous preterm labor, fetal growth restriction (FGR), proteinuric and non-proteinuric pregnancy induced hypertension (PIH), intrauterine fetal demise, oligohydramnios, spontaneous miscarriage and placental abruption) were evaluated, according to maternal PAPP-A MoM levels. Of the 1622 patients in the study, pregnancy complications were observed in 184 (11.3%). Patients with PAPP-A < or =0.25 MoM had significantly higher rates of FGR (RR = 3.12), proteinuric PIH (RR = 6.09), spontaneous miscarriage (RR = 8.76). No statistically significant differences were noted for other adverse outcomes evaluated Women with PAPP-A < or =0.50 MoM also had significantly higher rates of FGR (RR = 3.30) and spontaneous miscarriage (RR = 3.78). We conclude that decreased levels of first trimester maternal serum PAPP-A are predictive not only of chromosome anomalies but also of adverse pregnancy outcome.

Objective  To investigate the clinical and sonographic parameters associated with adverse fetal outcomes in patients with congenital parvovirus B19 infection managed by intrauterine transfusion. Methods  This was a single-center retrospective study conducted from January 2005 to December 2016 that assessed patients with singleton pregnancies with fetal parvovirus infection confirmed by a polymerase chain reaction of the amniotic fluid or fetal blood samples who underwent at least one intrauterine transfusion. The maternal characteristics, sonographic findings and parameters related to intrauterine transfusion were compared between the two groups (recovery/non-recovery), who were categorized based on fetal response after in-utero transfusions. Progression to fetal death or delivery without fetal recovery after the transfusions was considered non-recovery and categorized as an adverse outcome. Results  The final analysis included ten singleton pregnancies: seven of which were categorized into the recovery group and three of which into the non-recovery group. The baseline characteristics were similar between the groups. All fetuses were hydropic at the time of diagnosis. No significant differences related to sonographic or intrauterine transfusion parameters were identified between the groups; however, the non-recovery group tended to have an increased number of sonographic markers and lower fetal hemoglobin and platelet levels before the transfusion. Conclusion  We were unable to firmly establish the clinical or sonographic parameters associated with adverse fetal outcomes in patients with parvovirus infection managed with intrauterine transfusions; however, edema, placental thickening and oligohydramnios may indicate greater fetal compromise and, subsequently, adverse outcomes. However, further studies are necessary, mainly due to the small number of cases analyzed in the present study. Thieme Revinter Publicações Ltda Rio de Janeiro, Brazil.

Adverse events (AEs) among hospitalized patients occur frequently and result in significant sequelae. Federal policy is incentivizing health information technology (HIT) use, although research demonstrating safety benefits from HIT is mixed. Our objective was to evaluate the potential effects of HIT on reducing 21 different inpatient AEs. Identifying AEs most likely to be reduced by HIT can inform the design of future studies evaluating its effectiveness. We conducted a modified Delphi panel of national experts in HIT and safety. We conducted a focused literature review to inform the experts. Using a novel framework, experts rated each AE as 'definitely reduced by health IT,' 'possibly reduced by health IT' and 'not likely to be reduced by health IT'. From our panel discussion, experts identified six AEs as 'definitely reduced by health IT': (1) adverse drug events (ADEs) associated with digoxin; (2) ADE associated with IV heparin; (3) ADE associated with hypoglycaemic agents; (4) ADE associated with low molecular weight heparin and factor Xa inhibitor; (5) contrast nephropathy associated with catheter angiography; and (6) ADE hospital-acquired antibiotic-associated Clostridium difficile. Understanding the effects of HIT on patient outcomes will be essential to ensuring that the significant federal investment results in anticipated improvements. This study serves as an important early step in helping with the design of future work evaluating level of HIT infrastructure and rates of inpatient AEs. © 2014 John Wiley & Sons, Ltd.

Magnitude of income-related disparities in adverse perinatal outcomes

PubMed Central

2014-01-01

Background To assess and compare multiple measurements of socioeconomic position (SEP) in order to determine the relationship with adverse perinatal outcomes across various contexts. Methods A birth registry, the Nova Scotia Atlee Perinatal Database, was confidentially linked to income tax and related information for the year in which delivery occurred. Multiple logistic regression was used to examine odds ratios between multiple indicators of SEP and multiple adverse perinatal outcomes in 117734 singleton births between 1988 and 2003. Models for after tax family income were also adjusted for neighborhood deprivation to gauge the relative magnitude of effects related to SEP at both levels. Effects of SEP were stratified by single- versus multiple-parent family composition, and by urban versus rural location of residence. Results The risk of small for gestational age and spontaneous preterm birth was higher across all the indicators of lower SEP, while risk for large for gestational age was lower across indicators of lower SEP. Higher risk of postneonatal death was demonstrated for several measures of lower SEP. Higher material deprivation in the neighborhood of residence was associated with increased risk for perinatal death, small for gestational age birth, and iatrogenic and spontaneous preterm birth. Family composition and urbanicity were shown to modify the association between income and some perinatal outcomes. Conclusions This study highlights the importance of understanding the definitions of SEP and the mechanisms that lead to the association between income and poor perinatal outcomes, and broadening the types of SEP measures used in some cases.

Objective To derive and validate a risk score for an adverse clinical outcome in adults with meningitis and a negative cerebrospinal fluid (CSF) Gram stain. Patients and Methods We conducted a retrospective study of 567 adults from Houston, Texas, with meningitis evaluated between January 1, 2005, and January 1, 2010. The patients were divided into derivation (N=292) and validation (N=275) cohorts. An adverse clinical outcome was defined as a Glasgow Outcome Scale score of 4 or less. Results Of the 567 patients, 62 (11%) had an adverse clinical outcome. A predictive model was created using 3 baseline variables that were independently associated with an adverse clinical outcome (P<.05): age greater than 60 years, abnormal findings on neurologic examination (altered mental status, focal neurologic deficits, or seizures), and CSF glucose level of less than 2.4975 mmol/L (to convert CSF glucose to mmol/L, multiply by 0.05551). The model classified patients into 2 categories of risk for an adverse clinical outcome—derivation sample: low risk, 0.6% and high risk, 32.8%; P<.001; and validation sample: low risk, 0.5% and high risk, 21.1%; P<.001. Conclusion Adults with meningitis and a negative CSF Gram stain can be accurately stratified for the risk of an adverse clinical outcome using clinical variables available at presentation.

To determine whether Part D coverage gap entry is associated with risk of death or hospitalization for cardiovascular outcomes. Prospective cohort study. Beneficiaries entered the study upon reaching the coverage gap spending threshold and were observed until an outcome reaching the threshold for catastrophic coverage occurred or year's end. Nine thousand four hundred thirty-six exposed individuals (those who were responsible for drug costs in the gap) were compared with 9,436 unexposed individuals (those who received financial assistance) based on propensity score (PS) or high-dimensional propensity score (hdPS). Medicare Part D drug insurance. Three hundred three thousand nine hundred seventy-eight Medicare beneficiaries aged 65 and older in 2006 and 2007 with linked prescription and medical claims who enrolled in stand-alone Part D or retiree drug plans and reached the gap spending threshold. Rates of death and hospitalization for any of five cardiovascular outcomes, including acute coronary syndrome with revascularization (ACS), after reaching the coverage gap spending threshold were compared using Cox proportional hazards models. In PS-matched analyses, exposed beneficiaries had higher, albeit not significantly so, hazard of death (hazard ratio (HR) = 1.25, 95% confidence interval (CI) = 0.98-1.59) and ACS (HR = 1.16, 95% CI = 0.83-1.62) than unexposed beneficiaries. hdPS-matched analyses minimized residual confounding and confirmed results (death: HR = 0.99, 95% CI = 0.78-1.24; ACS: HR = 1.07, 95% CI = 0.81-1.41). Exposed beneficiaries were no more or less likely to experience other outcomes than were those who were unexposed. During the short-term coverage gap period, having no financial assistance to pay for drugs was not associated with greater risk of death or hospitalization for cardiovascular causes, although long-term health consequences remain unclear. © 2012, Copyright the Authors Journal compilation © 2012, The American Geriatrics Society.

2017-08-11

The objective of this study was to systematically review the published literature for risk factors associated with adverse outcomes in older adults sustaining blunt chest trauma. EMBASE and MEDLINE were searched from inception until March 2017 for prognostic factors associated with adverse outcomes in older adults sustaining blunt chest trauma using a pre-specified search strategy. References were independently screened for inclusion by two reviewers. Study quality was assessed using the Quality in Prognostic Studies tool. Where appropriate, descriptive statistics were used to evaluate study characteristics and predictors of adverse outcomes. Thirteen cohort studies representing 79,313 patients satisfied our selection criteria. Overall, 26 prognostic factors were examined across studies and were reported for morbidity (8 studies), length of stay (7 studies), mortality (6 studies), and loss of independence (1 study). No studies examined patient quality of life or emergency department recidivism. Prognostic factors associated with morbidity and mortality included age, number of rib fractures, and injury severity score. Although age and rib fractures were found to be associated with adverse outcomes in more than 3 studies, meta-analysis was not performed due to heterogeneity amongst included studies in how these variables were measured. While blunt chest wall trauma in older adults is relatively common, the literature on prognostic factors for adverse outcomes in this patient population remains inadequate due to a paucity of high quality studies and lack of consistent reporting standards.

Researchers in Vietnam reported a high percentage of pregnant women attending ANC at least once, but an insufficient utilization of ANC services remains. The evidence demonstrating how the utilization of these services affect pregnancy outcome is not documented in Vietnam. We investigated the association between the misuse of ANC services and pregnancy outcome, and assessed other determinants associated with ANC services utilization. We conducted a prospective community-based study in Trang Bom district, Dong Nai, during 12 consecutive months. Data were collected using a structured questionnaire and medical records. Women were followed up to delivery. Misuse of ANC services, related factors and its association with adverse events were assessed using logistic regression. Out of 3301 pregnant women, 91% initiated an ANC visit within first trimester, 95% attended at least three ANC visits, but a low percentage of pregnant women underwent blood and urine tests at least once (20% and 39%, respectively). Factors significantly associated with a higher risk of adverse outcomes were lack of blood test and urine test, parity ≥ 3, ANC visits < 3, history of an adverse outcome, and having a clinical condition. Blood and urine tests were less frequently used by young women, women from ethnic minorities, women using only private facilities for ANC attendance, and women with a low number of ANC visits. Despite a high percentage of early entry into ANC and of at least three ANC visits, misuse of ANC services still exists and contributes to adverse outcomes. There is a need to increase the awareness of women on the benefits of ANC services by educating young women as well as women with several children. Health workers should be encouraged to propose suitable ANC services to pregnant women.

The utility value attributed to taking pills for prevention can have a major effect on the cost-effectiveness of interventions, but few published studies have systematically quantified this value. We sought to quantify the utility value of taking pills used for prevention of cardiovascular disease (CVD). Cross-sectional survey. Central North Carolina. 708 healthcare employees aged 18 years and older. Utility values for taking 1 pill/day, assessed using time trade-off, modified standard gamble and willingness-to-pay methods. Mean age of respondents was 43 years (19-74). The majority of the respondents were female (83%) and Caucasian (80%). Most (80%) took at least 2 pills/day. Mean utility values for taking 1 pill/day using the time trade-off method were: 0.9972 (95% CI 0.9962 to 0.9980). Values derived from the standard gamble and willingness-to-pay methods were 0.9967 (0.9954 to 0.9979) and 0.9989 (95% CI 0.9986 to 0.9991), respectively. Utility values varied little across characteristics such as age, sex, race, education level or number of pills taken per day. The utility value of taking pills daily in order to prevent an adverse CVD health outcome is approximately 0.997. Published by the BMJ Publishing Group Limited.

Abstract Outcomes after surgeries involving physicians as patients have not been researched. This study compares postoperative adverse events between physicians as surgical patients and nonhealth professional controls. Using reimbursement claims data from Taiwan's National Health Insurance Program, we conducted a matched retrospective cohort study of 7973 physicians as surgical patients and 7973 propensity score–matched nonphysician controls receiving in-hospital major surgeries between 2004 and 2010. We compared postoperative major complications, length of hospital stay, intensive care unit (ICU), medical expenditure, and 30-day mortality. Compared with nonphysician controls, physicians as surgical patients had lower adjusted odds ratios (ORs) with 95% confidence intervals (CIs) of postoperative deep wound infection (OR 0.63, 95% CI 0.40–0.99; P < 0.05), prolonged length of stay (OR 0.68, 95% CI 0.62–0.75; P < 0.0001), ICU admission (OR 0.74, 95% CI 0.66–0.83; P < 0.0001), and increased medical expenditure (OR 0.80, 95% CI 0.73–0.88; P < 0.0001). Physicians as surgical patients were not associated with 30-day in-hospital mortality after surgery. Physicians working at medical centers (P < 0.05 for all), dentists (P < 0.05 for all), and those with fewer coexisting medical conditions (P < 0.05 for all) had lower risks for postoperative prolonged length of stay, ICU admission, and increased medical expenditure. Although our study's findings suggest that physicians as surgical patients have better outcomes after surgery, future clinical prospective studies are needed for validation. PMID:27684836

Chemical regulation is challenged by the large number of chemicals requiring assessment for potential human health and environmental impacts. Current approaches are too resource intensive in terms of time, money and animal use to evaluate all chemicals under development or already on the market. The need for timely and robust decision making demands that regulatory toxicity testing becomes more cost-effective and efficient. One way to realize this goal is by being more strategic in directing testing resources; focusing on chemicals of highest concern, limiting testing to the most probable hazards, or targeting the most vulnerable species. Hypothesis driven Integrated Approaches to Testing and Assessment (IATA) have been proposed as practical solutions to such strategic testing. In parallel, the development of the Adverse Outcome Pathway (AOP) framework, which provides information on the causal links between a molecular initiating event (MIE), intermediate key events (KEs) and an adverse outcome (AO) of regulatory concern, offers the biological context to facilitate development of IATA for regulatory decision making. This manuscript summarizes discussions at the Workshop entitled "Advancing AOPs for Integrated Toxicology and Regulatory Applications" with particular focus on the role AOPs play in informing the development of IATA for different regulatory purposes.

We describe adverse pregnancy outcomes, including congenital anomalies, fetal, neonatal, and infant mortality among a Missouri population of low-income, rural mothers who participated in two randomized smoking cessation trials. In the Baby BEEP (BB) trial, 695 rural women were recruited from 21 WIC clinics with 650 women's pregnancy outcomes known (93.5% retention rate). Following the BB trial, 298 women who had a live infant after November 2004 were recruited again into and completed the Baby Beep for Kids (BBK) trial. Simple statistics describing the population and perinatal and postneonatal mortality rates were calculated. Of the adverse pregnancy outcomes (n = 79), 29% were spontaneous abortions of less than 20 weeks' gestation, 23% were premature births, and 49% were identified birth defects. The perinatal mortality rate was 15.9 per 1000 births (BB study) compared with 8.6 per 1000 births (state of Missouri) and 8.5 per 1000 births (United States). The postneonatal infant mortality rate was 13.4 per 1000 live births (BBK) compared with 2.1 per 1000 live births (United States). The health disparity in this population of impoverished, rural, pregnant women who smoke, particularly in regard to perinatal and infant deaths, warrants attention.

2002-01-01

The implementation of the Balanced Budget Act (BBA) of 1997 resulted in substantial decreases in the amount of Medicare home health use. Use among home health users decreased by two-fifths from fiscal year (FY) 1997, just before the passage of the BBA to FY 1999, the first full year after the implementation of the home health interim payment system. This article examines whether these dramatic reductions in use resulted in increased incidence of potential adverse outcomes, i.e., increases in hospitalizations, skilled nursing home facility admissions, emergency room (ER) use, or death among home health users.

Industrial wind turbines and adverse health effects.

PubMed

Jeffery, Roy D; Krogh, Carmen M E; Horner, Brett

2014-01-01

Some people living in the environs of industrial wind turbines (IWTs) report experiencing adverse health and socioeconomic effects. This review considers the hypothesis that annoyance from audible IWTs is the cause of these adverse health effects. We searched PubMed and Google Scholar for articles published since 2000 that included the terms "wind turbine health," "wind turbine infrasound," "wind turbine annoyance," "noise annoyance" or "low frequency noise" in the title or abstract. Industrial wind turbines produce sound that is perceived to be more annoying than other sources of sound. Reported effects from exposure to IWTs are consistent with well-known stress effects from persistent unwanted sound. If placed too close to residents, IWTs can negatively affect the physical, mental and social well-being of people. There is sufficient evidence to support the conclusion that noise from audible IWTs is a potential cause of health effects. Inaudible low-frequency noise and infrasound from IWTs cannot be ruled out as plausible causes of health effects.

The adverse outcome pathway concept: a pragmatic tool in toxicology.

PubMed

Vinken, Mathieu

2013-10-04

Adverse outcome pathways (AOPs) are novel tools in toxicology and human risk assessment with broad potential. AOPs are designed to provide a clear-cut mechanistic representation of critical toxicological effects that span over different layers of biological organization. AOPs share a common structure consisting of a molecular initiating event, a series of intermediate steps and key events, and an adverse outcome. Development of AOPs ideally complies with OECD guidelines. This also holds true for AOP evaluation, which includes consideration of the Bradford Hill criteria for weight-of-evidence assessment and meeting a set of key questions defined by the OECD. Elaborate AOP frameworks have yet been proposed for chemical-induced skin sensitization, cholestasis, liver fibrosis and liver steatosis. These newly postulated AOPs can serve a number of ubiquitous purposes, including the establishment of (quantitative) structure-activity relationships, the development of novel in vitro toxicity screening tests and the elaboration of prioritization strategies.

Background: With improved survival, more bone sarcoma survivors are approaching middle age making it crucial to investigate the late effects of their cancer and its treatment. We investigated the long-term risks of adverse outcomes among 5-year bone sarcoma survivors within the British Childhood Cancer Survivor Study. Methods: Cause-specific mortality and risk of subsequent primary neoplasms (SPNs) were investigated for 664 bone sarcoma survivors. Use of health services, health and marital status, alcohol and smoking habits, and educational qualifications were investigated for survivors who completed a questionnaire. Results: Survivors were seven times more likely to experience all-cause mortality than expected, and there were substantial differences in risk depending on tumour type. Beyond 25 years follow-up the risk of dying from all-causes was comparable to the general population. This is in contrast to dying before 25 years where the risk was 12.7-fold that expected. Survivors were also four times more likely to develop a SPN than expected, where the excess was restricted to 5–24 years post diagnosis. Increased health-care usage and poor health status were also found. Nonetheless, for some psychosocial outcomes survivors were better off than expected. Conclusions: Up to 25 years after 5-year survival, bone sarcoma survivors are at substantial risk of death and SPNs, but this is greatly reduced thereafter. As 95% of all excess deaths before 25 years follow-up were due to recurrences and SPNs, increased monitoring of survivors could prevent mortality. Furthermore, bone and breast SPNs should be a particular concern. Since there are variations in the magnitude of excess risk depending on the specific adverse outcome under investigation and whether the survivors were initially diagnosed with osteosarcoma or Ewing sarcoma, risks need to be assessed in relation to these factors. These findings should provide useful evidence for risk stratification and updating

Background Even when tuberculosis (TB) treatment is free, hidden costs incurred by patients and their households (TB-affected households) may worsen poverty and health. Extreme TB-associated costs have been termed “catastrophic” but are poorly defined. We studied TB-affected households' hidden costs and their association with adverse TB outcome to create a clinically relevant definition of catastrophic costs. Methods and Findings From 26 October 2002 to 30 November 2009, TB patients (n = 876, 11% with multi-drug-resistant [MDR] TB) and healthy controls (n = 487) were recruited to a prospective cohort study in shantytowns in Lima, Peru. Patients were interviewed prior to and every 2–4 wk throughout treatment, recording direct (household expenses) and indirect (lost income) TB-related costs. Costs were expressed as a proportion of the household's annual income. In poorer households, costs were lower but constituted a higher proportion of the household's annual income: 27% (95% CI = 20%–43%) in the least-poor houses versus 48% (95% CI = 36%–50%) in the poorest. Adverse TB outcome was defined as death, treatment abandonment or treatment failure during therapy, or recurrence within 2 y. 23% (166/725) of patients with a defined treatment outcome had an adverse outcome. Total costs ≥20% of household annual income was defined as catastrophic because this threshold was most strongly associated with adverse TB outcome. Catastrophic costs were incurred by 345 households (39%). Having MDR TB was associated with a higher likelihood of incurring catastrophic costs (54% [95% CI = 43%–61%] versus 38% [95% CI = 34%–41%], p<0.003). Adverse outcome was independently associated with MDR TB (odds ratio [OR] = 8.4 [95% CI = 4.7–15], p<0.001), previous TB (OR = 2.1 [95% CI = 1.3–3.5], p = 0.005), days too unwell to work pre-treatment (OR = 1.01 [95% CI = 1.00–1.01], p = 0.02), and catastrophic costs (OR = 1

Even when tuberculosis (TB) treatment is free, hidden costs incurred by patients and their households (TB-affected households) may worsen poverty and health. Extreme TB-associated costs have been termed "catastrophic" but are poorly defined. We studied TB-affected households' hidden costs and their association with adverse TB outcome to create a clinically relevant definition of catastrophic costs. From 26 October 2002 to 30 November 2009, TB patients (n = 876, 11% with multi-drug-resistant [MDR] TB) and healthy controls (n = 487) were recruited to a prospective cohort study in shantytowns in Lima, Peru. Patients were interviewed prior to and every 2-4 wk throughout treatment, recording direct (household expenses) and indirect (lost income) TB-related costs. Costs were expressed as a proportion of the household's annual income. In poorer households, costs were lower but constituted a higher proportion of the household's annual income: 27% (95% CI = 20%-43%) in the least-poor houses versus 48% (95% CI = 36%-50%) in the poorest. Adverse TB outcome was defined as death, treatment abandonment or treatment failure during therapy, or recurrence within 2 y. 23% (166/725) of patients with a defined treatment outcome had an adverse outcome. Total costs ≥20% of household annual income was defined as catastrophic because this threshold was most strongly associated with adverse TB outcome. Catastrophic costs were incurred by 345 households (39%). Having MDR TB was associated with a higher likelihood of incurring catastrophic costs (54% [95% CI = 43%-61%] versus 38% [95% CI = 34%-41%], p<0.003). Adverse outcome was independently associated with MDR TB (odds ratio [OR] = 8.4 [95% CI = 4.7-15], p<0.001), previous TB (OR = 2.1 [95% CI = 1.3-3.5], p = 0.005), days too unwell to work pre-treatment (OR = 1.01 [95% CI = 1.00-1.01], p = 0.02), and catastrophic costs (OR = 1.7 [95% CI = 1.1-2.6], p = 0.01).

Poor mental health in junior clinicians is prevalent and may lead to poor productivity and significant medical errors. We aimed to provide contemporary data on the mental health of surgical trainees and identify risk factors relating to poorer mental health outcomes. A detailed questionnaire was developed comprising questions based on the 36-item short-form health survey (SF-36) and Physical Activity Questionnaire. Each of the questionnaires has proven validity and reliability in the clinical context. Ethics approval was obtained from the Royal Australasian College of Surgeons. The questionnaire was aimed at surgical registrars. We used Physical Activity Questionnaire, SF-36 scores and linear regression to evaluate the effect of putative predictors on mental health. A total of 83 responses were collected during the study period, of which 49 (59%) were from men and 34 (41%) were from women. The mean Mental Component Summary (MCS) score for both sexes was significantly lower than the population mean at ages 25-34 (p < 0.001). Poor satisfaction with one's work culture and a feeling of a lack of support at work were extremely strong predictors of a lower MCS score (p < 0.001). Hours of overtime worked, particularly unpaid overtime, were also strong predictors of a poorer score. Australian surgical trainees reported lower MCS scores from the SF-36 questionnaire compared to the general population. Increasing working hours, unpaid overtime, poor job security, and job satisfaction were associated with poorer scores among trainees. Interventions providing improved working conditions need to be considered by professional training bodies and employers. Copyright © 2018 Association of Program Directors in Surgery.

To examine associations between adverse childhood experiences (ACEs) in early childhood and teacher-reported academic and behavioral problems in kindergarten. We conducted a secondary analysis of data from the Fragile Families and Child Wellbeing Study, a national urban birth cohort. Subjects with primary caregiver-reported information on ACE exposures ascertained at 5 years and teacher-reported outcomes at the end of the child's kindergarten year were included. Outcomes included teacher ratings of academic skills, emergent literacy skills, and behavior. We included 8 ACE exposures on the basis of the original Centers for Disease Control and Prevention Kaiser study and created an ACE score by summing individual adversities. We examined the associations between teacher-reported academic and behavioral outcomes and ACE scores by using logistic regression. In the study sample, 1007 children were included. Fifty-five percent had experienced 1 ACE and 12% had experienced ≥ 3. Adjusting for potential confounders, experiencing ≥ 3 ACEs was associated with below-average language and literacy skills (adjusted odds ratio [AORs]: 1.8; 95% confidence interval [CI]: 1.1-2.9) and math skills (AOR: 1.8, 95% CI: 1.1-2.9), poor emergent literacy skills, attention problems (AOR: 3.5, 95% CI: 1.8-6.5), social problems (AOR: 2.7, 95% CI: 1.4-5.0), and aggression (AOR: 2.3, 95% CI: 1.2-4.6). In this study of urban children, experiencing ACEs in early childhood was associated with below-average, teacher-reported academic and literacy skills and behavior problems in kindergarten. These findings underscore the importance of integrated approaches that promote optimal development among vulnerable children. Copyright © 2016 by the American Academy of Pediatrics.

Childhood adversity is highly prevalent and associated with risk for poor health outcomes in childhood and throughout the life course. Empirical literature on resilience over the past 40 years has identified protective factors for traumatized children that improve health outcomes. Despite these empirical investigations of resilience, there is limited integration of these findings into proactive strategies to mitigate the impact of adverse childhood experiences. We review the state of resilience research, with a focus on recent work, as it pertains to protecting children from the health impacts of early adversity. We identify and document evidence for 5 modifiable resilience factors to improve children's long- and short-term health outcomes, including fostering positive appraisal styles in children and bolstering executive function, improving parenting, supporting maternal mental health, teaching parents the importance of good self-care skills and consistent household routines, and offering anticipatory guidance about the impact of trauma on children. We conclude with 10 recommendations for pediatric practitioners to leverage the identified modifiable resilience factors to help children withstand, adapt to, and recover from adversity. Taken together, these recommendations constitute a blueprint for a trauma-informed medical home. Building resilience in pediatric patients offers an opportunity to improve the health and well-being of the next generation, enhance national productivity, and reduce spending on health care for chronic diseases.

BACKGROUND The aim was to evaluate the impact of early pregnancy events and complications as predictors of adverse obstetric outcome. METHODS We conducted a literature review on the impact of first trimester complications in previous and index pregnancies using Medline and Cochrane databases covering the period 1980-2008. RESULTS Clinically relevant associations of adverse outcome in the subsequent pregnancy with an odds ratio (OR) > 2.0 after complications in a previous pregnancy are the risk of perinatal death after a single previous miscarriage, the risk of very preterm delivery (VPTD) after two or more miscarriages, the risk of placenta praevia, premature preterm rupture of membranes, VPTD and low birthweight (LBW) after recurrent miscarriage and the risk of VPTD after two or more termination of pregnancy. Clinically relevant associations of adverse obstetric outcome in the ongoing pregnancy with an OR > 2.0 after complications in the index pregnancy are the risk of LBW and very low birthweight (VLBW) after a threatened miscarriage, the risk of pregnancy-induced hypertension, pre-eclampsia, placental abruption, preterm delivery (PTD), small for gestational age and low 5-min Apgar score after detection of an intrauterine haematoma, the risk of VPTD and intrauterine growth restriction after a crown-rump length discrepancy, the risk of VPTD, LBW and VLBW after a vanishing twin phenomenon and the risk of PTD, LBW and low 5-min Apgar score in a pregnancy complicated by severe hyperemesis gravidarum. CONCLUSIONS Data from our literature review indicate, by finding significant associations, that specific early pregnancy events and complications are predictors for subsequent adverse obstetric and perinatal outcome. Though, some of these associations are based on limited or small uncontrolled studies. Larger population-based controlled studies are needed to confirm these findings. Nevertheless, identification of these risks will improve obstetric care.

Sexually transmitted infections (STIs) in pregnancy such as Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) may lead to adverse infant outcomes. Individual urine specimens from HIV-infected pregnant women diagnosed with HIV during labor were collected at the time of infant birth and tested by polymerase chain reaction for CT and NG. Infant HIV infection was determined at 3 months with morbidity/mortality assessed through 6 months. Of 1373 maternal urine samples, 277 (20.2%) were positive for CT and/or NG; 249 (18.1%) for CT, 63 (4.6%) for NG and 35 (2.5%) for both CT and NG. HIV infection was diagnosed in 117 (8.5%) infants. Highest rates of adverse outcomes (sepsis, pneumonia, congenital syphilis, septic arthritis, conjunctivitis, low birth weight, preterm delivery and death) were noted in infants of women with CT and NG (23/35, 65.7%) compared with NG (16/28, 57.1%), CT (84/214, 39.3%) and no STI (405/1096, 37%, P = 0.001). Death (11.4% vs. 3%, P = 0.02), low birth weight (42.9% vs. 16.9%, P = 0.001) and preterm delivery (28.6% vs. 10.2%, P = 0.008) were higher among infants of CT and NG-coinfected women. Infants who had any adverse outcome and were born to women with CT and/or NG were 3.5 times more likely to be HIV infected after controlling for maternal syphilis (odds ratio: 3.5, 95% confidence interval: 1.4-8.3). By adjusted multivariate logistic regression, infants born to mothers with any CT and/or NG were 1.35 times more likely to have an adverse outcome (odds ratio, 1.35; 95% confidence interval, 1.03-1.76). STIs in HIV-infected pregnant women are associated with adverse outcomes in HIV-exposed infected and uninfected infants.
