Childhood adversities have been associated with a number of medical and psychiatric outcomes. However, the reported effects that specific childhood adversities have on suicidality vary across studies. This was a cross-sectional, stratified, multistage area probability investigation of a general population in Brazil, designated the São Paulo Megacity Mental Health Survey. The World Mental Health Composite International Diagnostic Interview was applied in 5037 individuals ≥ 18 years of age, in order to assess 12 different adversities occurring during childhood and/or adolescence, as well as to look for associations between those adversities and subsequent suicidality in different age strata. Over half of the respondents reported at least one childhood adversity. Only physical abuse was consistently associated with suicide attempts in all subsequent life stages (OR = 2.1). Among adults 20-29 years of age, the likelihood of a suicide attempt was correlated with parental divorce, whereas suicidal ideation was associated with prior sexual abuse. Among adults over 30 years of age, physical illness and economic adversity emerged as relevant childhood adversities associated with suicide attempts, whereas sexual abuse, family violence, and economic adversity were associated with suicidal ideation. Childhood adversities, especially physical abuse, are likely associated with unfavorable consequences in subsequent years. For suicidality across a lifespan, the role of different childhood adversities must be examined independently.

Adverse childhood experiences, comprised of forms of maltreatment and certain dysfunctional household environments, can affect the development of a child in a variety of different ways. This multitude of developmental changes may subsequently produce compounding harmful effects on the child's life and increase acutely maladaptive outcomes, including adolescent suicidal behavior. This study uses data collected from 2007 to 2012 for 64,329 Florida Department of Juvenile Justice youth (21.67 % female, 42.88 % African American, and 15.37 % Hispanic) to examine the direct and indirect effects of adverse childhood experiences on suicide attempts. Using a generalized structural equation model, the effects of adverse childhood experience scores are estimated on suicidal behavior through pathways of certain aspects of a child's personality development (aggression and impulsivity), as well as adolescent problem behaviors (school difficulties and substance abuse). The results show that a large proportion of the relationship between childhood adversity and suicide is mediated by the aforementioned individual characteristics, specifically through the youth's maladaptive personality development. These results suggest that, if identified early enough, the developmental issues for these youth could potentially be addressed in order to thwart potential suicidal behavior.

The importance of adverse reactions in terms of donor safety recently has received significant attention, but their role in subsequent donation behavior has not been thoroughly investigated. Six REDS-II blood centers provided data for this analysis. Summary minor and major adverse reaction categories were created. The influence of adverse reactions on donation was examined in two ways: Kaplan-Meier curves were generated to determine the cumulative pattern of first return, and adjusted odds ratios (AORs) for demographic and other factors positively and negatively associated with return were estimated using multivariable logistic regression. Donors who had major reactions had longer times to return than donors with minor or no reactions. The AOR of returning for donors with major reactions was 0.32 (95% confidence interval [CI], 0.28-0.37) and with minor reactions 0.59 (95% CI, 0.56-0.62) when compared to donors who did not have reactions. Conversely, the most important factors positively associated with return were the number of donations in the previous year and increasing age. Subsequent return, whether a major, minor, or no reaction occurred, varied by blood center. Factors that are associated with the risk of having adverse reactions were not substantial influences on the return after adverse reactions. Having an adverse reaction leads to significantly lower odds of subsequent donation irrespective of previous donation history. Factors that have been associated with a greater risk of adverse reactions were not important positive or negative predictors of return after a reaction. © 2011 American Association of Blood Banks.

Results are reported from a study of the refrigerated shelf life of a number of irradiated foods. Data are included on shrimp, asparagus, snap beans, strawberries, sour cherries, blueberries, and lima beans. Surface irradiation did not retard ripening or cause significant organoleptic changes on hard ripe Elberta peaches, Kiefer or Bartlett pears, or Wealthy apples. The skin color of Double Red Delicious apples was adversely affected by refrigerated storage subsequent to irradiation. (C.H.)

Defining clinical deterioration.

2013-08-01

To review literature reporting adverse events and physiological instability in order to develop frameworks that describe and define clinical deterioration in hospitalised patients. Literature review of publications from 1960 to August 2012. Conception and refinement of models to describe clinical deterioration based on prevailing themes that developed chronologically in adverse event literature. We propose four frameworks or models that define clinical deterioration and discuss the utility of each. Early attempts used retrospective chart review and focussed on the end result of deterioration (adverse events) and iatrogenesis. Subsequent models were also retrospective, but used discrete complications (e.g. sepsis, cardiac arrest) to define deterioration, had a more clinical focus, and identified the concept of antecedent physiological instability. Current models for defining clinical deterioration are based on the presence of abnormalities in vital signs and other clinical observations and attempt to prospectively assist clinicians in predicting subsequent risk. However, use of deranged vital signs in isolation does not consider important patient-, disease-, or system-related factors that are known to adversely affect the outcome of hospitalised patients. These include pre-morbid function, frailty, extent and severity of co-morbidity, nature of presenting illness, delays in responding to deterioration and institution of treatment, and patient response to therapy. There is a need to develop multiple-variable models for deteriorating ward patients similar to those used in intensive care units. Such models may assist clinician education, prospective and real-time patient risk stratification, and guide quality improvement initiatives that prevent and improve response to clinical deterioration.

Exposure to Poverty and Productivity.

2017-01-01

We study whether exposure to poverty can induce affective states that decrease productivity. In a controlled laboratory setting, we find that subjects randomly assigned to a treatment, in which they view a video featuring individuals that live in extreme poverty, exhibit lower subsequent productivity compared to subjects assigned to a control treatment. Questionnaire responses, as well as facial recognition software, provide quantitative measures of the affective state evoked by the two treatments. Subjects exposed to images of poverty experience a more negative affective state than those in the control treatment. Further analysis shows that individuals in a more positive emotional state exhibit less of a treatment effect. Also, those who exhibit greater attentiveness upon viewing the poverty video are less productive. The results are consistent with the notion that exposure to poverty can induce a psychological state in individuals that adversely affects productivity.

The current study aims to determine whether elderly Holocaust survivors are affected differently from non-survivors by the adversity of aging and cancer. Holocaust survivors and non-survivors suffering from cancer, were assessed tapping PTSD, psychiatric symptomatology, psychosocial adjustment to illness and coping with the aftermath of the Holocaust. Findings indicate a significant difference between survivors and non-survivors in post-traumatic symptoms and their intensity, survivors endorsing significantly more PTSD symptoms. Survivors were classified into 3 sub-groups, namely "Victims," "Fighters," and "Those who made it". "Victims" reported the highest percentage of persons who met PTSD, psychiatric symptomatology and difficulty coping with the problems of old age. The diversity of responses points to heterogeneity of long-term adaptation and adjustment among Holocaust survivors and similar response to subsequent adversity.

Resilience as Regulation of Developmental and Family Processes

PubMed Central

MacPhee, David; Lunkenheimer, Erika; Riggs, Nathaniel

2015-01-01

Resilience can be defined as establishing equilibrium subsequent to disturbances to a system caused by significant adversity. When families experience adversity or transitions, multiple regulatory processes may be involved in establishing equilibrium, including adaptability, regulation of negative affect, and effective problem-solving skills. The authors’ resilience-as-regulation perspective integrates insights about the regulation of individual development with processes that regulate family systems. This middle-range theory of family resilience focuses on regulatory processes across levels that are involved in adaptation: whole-family systems such as routines and sense of coherence; coregulation of dyads involving emotion regulation, structuring, and reciprocal influences between social partners; and individual self-regulation. Insights about resilience-as-regulation are then applied to family-strengthening interventions that are designed to promote adaptation to adversity. Unresolved issues are discussed in relation to resilience-as-regulation in families, in particular how risk exposure is assessed, interrelations among family regulatory mechanisms, and how families scaffold the development of children’s resilience.

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 implications of partial and no recovery from delirium after hospital discharge are not clear. We sought to explore whether partial and no recovery from delirium among recently discharged patients predicted increased adverse events (emergency room visits, hospitalisations, death) during the subsequent 3 months. Prospective study of recovery from delirium in older hospital inpatients. The Confusion Assessment Method was used to diagnose delirium in hospital and determine recovery status after discharge (T0). Adverse events were determined during the 3 months T0. Survival analysis to the first adverse event and counting process modelling for one or more adverse events were used to examine associations between recovery status (ordinal variable, 0, 1 or 2 for full, partial or no recovery, respectively) and adverse events. Of 278 hospital inpatients with delirium, 172 were discharged before the assessment of recovery status (T0). Delirium recovery status at T0 was determined for 152: 25 had full recovery, 32 had partial recovery and 95 had no recovery. Forty-four patients had at least one adverse event during the subsequent 3 months. In multivariable analysis of one or more adverse events, poorer recovery status predicted increased adverse events; the hazard ratio (HR) (95% confidence interval, CI) was 1.72 (1.09, 2.71). The association of recovery status with adverse events was stronger among patients without dementia. Partial and no recovery from delirium after hospital discharge appear to predict increased adverse events during the subsequent 3 months These findings have potentially important implications for in-hospital and post-discharge management and policy.

We seek to describe the risk during 6 months and specific risk factors for recurrent falls, emergency department (ED) revisits, subsequent hospitalizations, and death within 6 months after a fall-related ED presentation. This was a secondary analysis of a retrospective cohort of elderly fall patients who presented to the ED from one urban teaching hospital. We included patients aged 65 years and older who had an ED fall visit in 2012. We examined the frequency and risk factors of adverse events (composite of recurrent falls, ED revisits, subsequent hospitalization, and death, selected a priori) at 6 months. Our study included 350 older adults. Adverse events steadily increased, from 7.7% at 7 days, 21.4% at 30 days, and 50.3% at 6 months. Within 6 months, 22.6% of patients had at least one recurrent fall, 42.6% revisited the ED, 31.1% had subsequent hospitalizations, and 2.6% died. In multivariable logistic regression analysis, psychological or sedative drug use predicted recurrent falls, ED revisits, subsequent hospitalizations, and adverse events. More than half of fall patients had an adverse event within 6 months of presenting to the ED after a fall. The risk during 6 months of these adverse events increased with psychological or sedative drug use. Larger future studies should confirm this association and investigate methods to minimize recurrent falls through management of such medications.

To elucidate whether repeated exposures to iodinated contrast media increase the risk of adverse reaction. We retrospectively reviewed 1,861 patients with hepatocellular carcinoma who visited authors' institution, a tertiary referral center, between 2004 and 2008. We analyzed cumulative probability of adverse reactions and risk factors. We categorized all symptoms into hypersensitivity reactions, physiologic reactions, and other reactions, according to the American College of Radiology guidelines, and evaluated each category as an event. We estimated the association between hazard for adverse reactions and the number of cumulative exposures to contrast media. We also evaluated subsequent contrast media injections and adverse reactions. There were 23,684 contrast media injections in 1,729 patients. One hundred and thirty-two patients were excluded because they were given no contrast media during the study period. Adverse reactions occurred in 196 (0.83%) patients. The cumulative incidence at 10(th), 20(th), and 30(th) examination was 7.9%, 15.2%, and 24.1%, respectively. Presence of renal impairment was found to be one of risk factors for adverse reactions. The estimated hazard of overall adverse reaction gradually decreased until around 10(th) exposure and rose with subsequent exposures. The estimated hazard of hypersensitivity showed V-shaped change with cumulative number of exposures. The estimated hazard of physiologic reaction had a tendency toward decreasing and that of other reaction had a tendency toward increasing. Second adverse reaction was more severe than the initial in only one among 130 patients receiving subsequent injections. Repeated exposures to iodinated contrast media increase the risk of adverse reaction.

Child Maltreatment and Children's Developmental Trajectories in Early- to Middle-Childhood

Associations between experiencing child maltreatment and adverse developmental outcomes are widely studied, yet conclusions regarding the extent to which effects are bidirectional, and whether they are likely causal, remain elusive. This study uses the Fragile Families and Child Well-Being study, a birth cohort of 4,898 children followed from birth through age 9. Hierarchical linear modeling and structural equation modeling are employed to estimate associations of maltreatment with cognitive and social-emotional well-being. Results suggest that effects of early childhood maltreatment emerge immediately, though developmental outcomes are also affected by newly occurring maltreatment over time. Additionally, findings indicate that children's early developmental scores predict their subsequent probability of experiencing maltreatment, though to a lesser extent than early maltreatment predicts subsequent developmental outcomes.

Impact of air pollutants on athletic performance

DOE Office of Scientific and Technical Information (OSTI.GOV)

Pierson, W.E.

Human controlled and observational studies both lead to the conclusion of air pollution adversely affecting athletic performance during training and competition. The dosage of various air pollutants during exercise is much higher due to the marked increase in ventilatory rate and concomitant nasal and oral breathing. This is particularly true for sulfur dioxide which is a highly water-soluble gas and is normally absorbed in the upper airway during nasal breathing. With heavy exercise, oral pharyngeal breathing is the predominant mode of breathing and much larger amounts of sulfur dioxide are delivered to the lower airway resulting in significant impact uponmore » the lower respiratory tract. More recently, several controlled human studies have shown that a combination of exercise and air pollutants such as ozone (O3) or sulfur dioxides (SO2) cause a significant increase in bronchoconstriction and air flow obstruction when compared to the same exposure at rest. In strenuous athletic competition such as the Olympic Games where small increments of time often determine the ultimate success of athletes, the impact of air pollutants and subsequent adverse ventilatory changes can affect athletic performance. 62 references.« less

Adversity in Preschool-Aged Children: Effects on Salivary Interleukin-1β

2016-01-01

Exposure to early life adversity is linked to impaired affective, cognitive, and behavioral functioning and increases risk for various psychiatric and medical conditions. Stress-induced increases in pro-inflammatory cytokines may be a biological mechanism of these effects. Few studies have examined cytokine levels in children experiencing early life adversity, and very little research has investigated cytokines or other markers of inflammation in saliva. In the present study, we examined salivary IL-1β and C-reactive protein (CRP) levels in relation to stress exposure in 40 children aged 3 to 5 years who were enrolled in a larger study of early life adversity. Childhood maltreatment status was assessed via review of child welfare records, and contextual stress exposure, traumatic life event history, and symptoms of psychopathology were assessed via caregiver interviews at a home visit. In a subsequent visit, salivary IL-1β and CRP were obtained before and after participation in four emotion-eliciting tasks. Number of past month contextual stressors, lifetime contextual stressors, and traumatic life events each demonstrated a significant main effect on IL-1β. Baseline IL-1β was positively associated with each of the significant main-effect adversities. Post-challenge IL-1β displayed positive associations with each adversity variable, but were not significant. CRP was not significantly associated with any of the adversity variables. Given evidence suggesting involvement of IL-1β in the neuropathology of psychiatric conditions, these results may have important implications for developmental outcomes. PMID:25997772

A document discusses a new, simplified method for cross-linking silica and other oxide aerogels, with a polymeric material to increase strength of such materials without adversely affecting porosity or low density. This innovation introduces the polymer precursor into the sol before gelation either as an agent, which co-reacts with the oxide gel, or as soluble polymer precursors, which do not interact with the oxide gel in any way. Subsequent exposure to heat, light, catalyst or other method of promoting polymerization causes cross-linking without any additional infiltration steps.

The influence of gravity on the process of development of animal systems

The development of animal systems is described in terms of a series of overlapping phases: pattern specification; differentiation; growth; and aging. The extent to which altered (micro) gravity (g) affects those phases is briefly reviewed for several animal systems. As a model, amphibian egg/early embryo is described. Recent data derived from clinostat protocols indicates that microgravity simulation alters early pattern specification (dorsal/ventral polarity) but does not adversely influence subsequent morphogenesis. Possible explanations for the absence of catastrophic microgravity effects on amphibian embryogenesis are discussed.

Background Former studies suggest that prior exposure to adverse experiences such as violence or sexual abuse increases vulnerability to posttraumatic stress reactions in victims of subsequent trauma. However, little is known about how such a history affects responses to terror in the general adolescent population. Objective To explore the role of prior exposure to adverse experiences as risk factors for posttraumatic stress reactions to the Oslo Terror events. Method We used data from 10,220 high school students in a large cross-sectional survey of adolescents in Norway that took place seven months after the Oslo Terror events. Prior exposure assessed was: direct exposure to violence, witnessing of violence, and unwanted sexual acts. We explored how these prior adversities interact with well-established risk factors such as proximity to the events, perceived life threat during the terror events, and gender. Results All types of prior exposure as well as the other risk factors were associated with terror-related posttraumatic stress reactions. The effects of prior adversities were, although small, independent of adolescents’ proximity to the terror events. Among prior adversities, only the effect of direct exposure to violence was moderated by perceived life threat. Exposure to prior adversities increased the risk of posttraumatic stress reactions equally for both genders, but proximity to the terror events and perceived life threat increased the risk more in females. Conclusions Terror events can have a more destabilizing impact on victims of prior adversities, independent of their level of exposure. The findings may be relevant to mental health workers and others providing post-trauma health care. PMID:24872862

Effects of applied voltages and dissolved oxygen on sustained power generation by microbial fuel cells.

2009-01-01

Oxygen intrusion into the anode chamber through proton exchange membrane can result in positive redox conditions in fed-batch, two chamber MFCs at the end of a cycle when the substrate is depleted. A slight increase in dissolved oxygen to 0.3 mg/L during MFC operation was not found to adversely affect power generation over subsequent cycles if sufficient substrate (acetate) was provided. Purging the anode chamber with air or pure oxygen for up to 10 days and 10 hrs also did not affect power generation, as power rapidly returned to previous levels when the chamber was sparged with nitrogen gas. When MFCs are connected in series, voltage reversal can occur resulting in a positive voltage applied to the anode biofilm. To investigate if this adversely affected the bacteria, voltages of 1, 2, 3, 4, and 9 V, were applied for 1 hr to the MFC before reconnecting it back to a fixed external load (1,000 Omega). A voltage of <2 V did not affect power generation. However, applying 3 V resulted in a 15 h lag phase before recovery, and 9 V produced a 60 h lag phase suggesting substantial damage to the bacteria that required re-growth of bacteria in the biofilm. These results indicate that charge reversal will be a more serious problem than oxygen intrusion into the anode chamber for sustained performance of MFCs.

Exposure to high levels of glucocorticoids (GCs) may adversely affect neuronal viability, particularly in the developing hippocampus, via increased function or sensitivity of N-methyl-D-aspartate (NMDA)-type glutamate receptors. Conversely, choline supplementation in the developing brain may reduce the severity of subsequent insult. The present studies aimed to examine the extent to which short-term exposure to high concentrations of corticosterone would produce neuronal injury mediated by NMDA receptor activity. These studies also assessed the ability of choline to prevent this form of injury via interactions with nicotinic acetylcholine receptors (nAChRs) expressing the alpha7 subunit. Organotypic hippocampal slice cultures derived from neonatal rat were pre-treated for 72 h with corticosterone (100 nM) alone or with choline (0.1-10 mM), prior to a brief (1 h) NMDA exposure (5 microM). NMDA exposure produced significant cellular damage, reflected as increased fluorescence of the non-vital marker propidium iodide, in the CA1 region. While exposure to corticosterone alone did not produce damage, pre-treatment of cultures with corticosterone markedly exacerbated NMDA-induced toxicity. Pre-treatment with choline (> or =1 mM) alone or in combination with corticosterone markedly reduced subsequent NMDA toxicity, effects blocked by co-exposure to methyllycaconitine (100 nM), an antagonist active at nAChRs expressing the alpha7 subunit. These data suggest that even short-term exposure to high concentrations of GCs may adversely affect neuronal viability and that choline supplementation protects the brain from NMDA receptor-mediated damage, including that associated with hypercortisolemia.

Health shocks adversely impact participation in the labour force in a working age population: a longitudinal analysis.

It is well understood that health affects labour force participation (LFP). However, much of the published research has been on older (retiring age) populations and using subjective health measures. This paper aims to assess the impact of an objective measure of 'health shock' (cancer registration or hospitalisation) on LFP in a working age population using longitudinal panel study data and fixed effect regression analyses. Seven waves of data from 2002-09 from the longitudinal Survey of Family, Income and Employment (SoFIE) were used, including working aged individuals who consented to have their survey information linked to health records (n=6,780). Fixed effect conditional logistic regression was used to model the impact of health shocks (hospitalisation or cancer registration) in the previous year on labour force participation at date of annual interview. Models were stratified by gender, age group (25-39 years, 40-54 years) and gender by age group. A health shock was associated with a significantly increased risk of subsequent non-participation in the labour force (odds ratio 1.54, 95%CI 1.30-1.82). Although interactions of age, sex and age by sex with health shock were not statistically significant, the association was largest in younger men and women. Using an objective measure of health, we have shown that a health shock adversely affects subsequent labour force participation. There are a number of policy and practice implications relating to support for working age people who have hospitalisations. © 2013 The Authors. ANZJPH © 2013 Public Health Association of Australia.

Growth and development in internationally adopted children: extent and timing of recovery after early adversity.

PubMed

Palacios, Jesús; Román, Maite; Camacho, Carlos

2011-03-01

Following initial adversity, internationally adopted children arrive with significant growth and developmental delays. Post-placement recovery has been widely documented, but little has been known about its extent and timing several years after placement and in children with diverse pre-adoptive experiences. A total of 289 children adopted from six countries into Spanish families were studied. Growth and psychological development were considered on arrival and after an average of over 3 years. Growth and developmental initial delays affected a substantial percentage of the children. Post-adoption recovery seemed quicker and more complete in weight and height than in head circumference and psychological development. Initial and later values were correlated, but growth-development relation on arrival subsequently lost significance. Most of the catch-up happened in the first three post-adoption years. Adoption offers an impressive opportunity for recovery after previous adversity, although continuity between past and present persists. The improvement is more marked in some areas than in others and more substantial in the first post-adoption years. © 2010 Blackwell Publishing Ltd.

Child maltreatment and children's developmental trajectories in early to middle childhood.

Font, Sarah A; Berger, Lawrence M

2015-01-01

Associations between experiencing child maltreatment and adverse developmental outcomes are widely studied, yet conclusions regarding the extent to which effects are bidirectional, and whether they are likely causal, remain elusive. This study uses the Fragile Families and Child Wellbeing Study, a birth cohort of 4,898 children followed from birth through age 9. Hierarchical linear modeling and structural equation modeling are employed to estimate associations of maltreatment with cognitive and social-emotional well-being. Results suggest that effects of early childhood maltreatment emerge immediately, though developmental outcomes are also affected by newly occurring maltreatment over time. Additionally, findings indicate that children's early developmental scores predict their subsequent probability of experiencing maltreatment, though to a lesser extent than early maltreatment predicts subsequent developmental outcomes. © 2014 The Authors.

2017-01-01

BACKGROUND: Infertility may indicate an underlying predisposition toward premature cardiovascular disease, yet little is known about potential long-term cardiovascular events following fertility therapy. We investigated whether failure of fertility therapy is associated with subsequent adverse cardiovascular events. METHODS: We performed a population-based cohort analysis of women who received gonadotropin-based fertility therapy between Apr. 1, 1993, and Mar. 31, 2011, distinguishing those who subsequently gave birth and those who did not. Using multivariable Poisson regression models, we estimated the relative rate ratio of adverse cardiovascular events associated with fertility therapy failure, accounting for age, year, baseline risk factors, health care history and number of fertility cycles. The primary outcome was subsequent treatment for nonfatal coronary ischemia, stroke, transient ischemic attack, heart failure or thromboembolism. RESULTS: Of 28 442 women who received fertility therapy, 9349 (32.9%) subsequently gave birth and 19 093 (67.1%) did not. The median number of fertility treatments was 3 (interquartile range 1–5). We identified 2686 cardiovascular events over a median 8.4 years of follow-up. The annual rate of cardiovascular events was 19% higher among women who did not give birth after fertility therapy than among those who did (1.08 v. 0.91 per 100 patient-years, p < 0.001), equivalent to a 21% relative increase in the annual rate (95% confidence interval 13%–30%). We observed no association between event rates and number of treatment cycles. INTERPRETATION: Fertility therapy failure was associated with an increased risk of long-term adverse cardiovascular events. These women merit surveillance for subsequent cardiovascular events.

In the developing world, large-scale projects in the extractive industry and natural resources sectors are often controversial and associated with long-term adverse health consequences to local communities. In many industrialised countries, health impact assessment (HIA) has been institutionalized for the mitigation of anticipated negative health effects while enhancing the benefits of projects, programmes and policies. However, in developing country settings, relatively few HIAs have been performed. Hence, more HIAs with a focus on low- and middle-income countries are needed to advance and refine tools and methods for impact assessment and subsequent mitigation measures. We present a promising HIA approach, developedmore » within the frame of a large gold-mining project in the Democratic Republic of the Congo. The articulation of environmental health areas, the spatial delineation of potentially affected communities and the use of a diversity of sources to obtain quality baseline health data are utilized for risk profiling. We demonstrate how these tools and data are fed into a risk analysis matrix, which facilitates ranking of potential health impacts for subsequent prioritization of mitigation strategies. The outcomes encapsulate a multitude of environmental and health determinants in a systematic manner, and will assist decision-makers in the development of mitigation measures that minimize potential adverse health effects and enhance positive ones.« less

Psychological sequelae of induced abortion.

PubMed

Romans-Clarkson, S E

1989-12-01

This article reviews the scientific literature on the psychological sequelae of induced abortion. The methodology and results of studies carried out over the last twenty-two years are examined critically. The unanimous consensus is that abortion does not cause deleterious psychological effects. Women most likely to show subsequent problems are those who were pressured into the operation against their own wishes, either by relatives or because their pregnancy had medical or foetal contraindications. Legislation which restricts abortion causes problems for women with unwanted pregnancies and their doctors. It is also unjust, as it adversely most affects lower socio-economic class women.

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.

Resiliency in the Face of Adversity: A Short Longitudinal Test of the Trait Hypothesis.

PubMed

Karaırmak, Özlem; Figley, Charles

2017-01-01

Resilience represents coping with adversity and is in line with a more positive paradigm for viewing responses to adversity. Most research has focused on resilience as coping-a state-based response to adversity. However, a competing hypothesis views resilience or resiliency as a trait that exists across time and types of adversity. We tested undergraduates enrolled in social work classes at a large southern university at two time periods during a single semester using measures of adversity, positive and negative affect, and trait-based resiliency. Consistent with the trait-based resiliency, and in contrast to state-based resilience, resiliency scores were not strongly correlated with adversity at both testing points but were with positive affect, and resiliency scores remained the same over time despite adversity variations. There was no gender or ethnic group difference in resilience scores. Black/African Americans reported significantly less negative affect and more positive affect than White/Caucasians.

Elevated aminopeptidase N affects sperm motility and early embryo development

PubMed Central

Ryu, Do-Yeal; Kwon, Woo-Sung

2017-01-01

Aminopeptidase N (APN) is a naturally occurring ectopeptidase present in mammalian semen. Previous studies have demonstrated that APN adversely affects male fertility through the alteration of sperm motility. This enzyme constitutes 0.5 to 1% of the seminal plasma proteins, which can be transferred from the prostasomes to sperms by a fusion process. In the present study, we investigated the molecular mechanism of action of APN and its role in regulating sperm functions and male fertility. In this in vitro study, epididymal mouse spermatozoa were incubated in a capacitating media (pH 7) containing 20 ng/mL of recombinant mouse APN for 90 min. Our results demonstrated that the supplementation of recombinant APN in sperm culture medium significantly increased APN activity, and subsequently altered motility, hyperactivated motility, rapid and medium swimming speeds, viability, and the acrosome reaction of mouse spermatozoa. These effects were potentially caused by increased toxicity in the spermatozoa. Further, altered APN activity in sperm culture medium affected early embryonic development. Interestingly, the effect of elevated APN activity in sperm culture medium was independent of protein tyrosine phosphorylation and protein kinase A activity. On the basis of these results, we concluded that APN plays a significant role in the regulation of several sperm functions and early embryonic development. In addition, increased APN activity could potentially lead to several adverse consequences related to male fertility. PMID:28859152

In this study, novel serological tests were used to detect tuberculosis (TB) in groups of farmed red deer (Cervus elaphus) varying in disease status or possible confounding factors. Groups of deer naturally or experimentally infected with Mycobacterium bovis and animals vaccinated against paratuberculosis were studied, as were uninfected animals and animals naturally or experimentally infected with Mycobacterium avium subsp. paratuberculosis. Sera were assayed using two rapid lateral-flow tests, Chembio's CervidTB STAT-PAK and DPP VetTB tests, and results were compared to those from tuberculin skin tests. Both serological tests had a high sensitivity, but specificity was adversely affected after animals had received a vaccine against paratuberculosis and were subsequently skin tested. The specificity of the DPP VetTB test was higher than that of the CervidTB STAT-PAK test, with natural infection with M. avium subsp. paratuberculosis adversely affecting the specificity of only the CervidTB STAT-PAK test. The sera from M. avium subsp. paratuberculosis-infected deer that produced false-positive reactions in the CervidTB STAT-PAK test were retested with a multiantigen print immunoassay (MAPIA), and some of these sera were shown to react with the MPB83 antigen. Combining the results from the serological tests and the skin tests showed only a slight increase in the sensitivity of detection of M. bovis-infected animals. It is concluded that both the CervidTB STAT-PAK and DPP VetTB tests offer rapid, convenient, and easy detection of bovine tuberculosis in deer, albeit with significant interference from paratuberculosis vaccination status and subsequent skin testing. The latter finding illustrates one of the limitations of currently available vaccines against paratuberculosis.

Fluoroquinolones and Tendinopathy: A Guide for Athletes and Sports Clinicians and a Systematic Review of the Literature

PubMed Central

Lewis, Trevor; Cook, Jill

2014-01-01

Context: Fluoroquinolone antibiotics have been used for several decades and are effective antimicrobials. Despite their usefulness as antibiotics, a growing body of evidence has accumulated in the peer-reviewed literature that shows fluoroquinolones can cause pathologic lesions in tendon tissue (tendinopathy). These adverse effects can occur within hours of commencing treatment and months after discontinuing the use of these drugs. In some cases, fluoroquinolone usage can lead to complete rupture of the tendon and substantial subsequent disability. Objective: To discuss the cause, pharmacology, symptoms, and epidemiology of fluoroquinolone-associated tendinopathy and to discuss the clinical implications with respect to athletes and their subsequent physiotherapy. Data Sources: We searched MEDLINE, Cumulative Index to Nursing and Allied Health (CINAHL), Allied and Complementary Medicine Database (AMED), and SPORTDiscus databases for available reports of fluoroquinolone-related tendinopathy (tendinitis, tendon pain, or rupture) published from 1966 to 2012. Search terms were fluoroquinolones or quinolones and tendinopathy, adverse effects, and tendon rupture. Included studies were written in or translated into English. Non—English–language and non-English translations of abstracts from reports were not included (n = 1). Study Selection: Eligible studies were any available reports of fluoroquinolone-related tendinopathy (tendinitis, tendon pain, or rupture). Both animal and human histologic studies were included. Any papers not focusing on the tendon-related side effects of fluoroquinolones were excluded (n = 71). Data Extraction: Data collected included any cases of fluoroquinolone-related tendinopathy, the particular tendon affected, type of fluoroquinolone, dosage, and concomitant risk factors. Any data outlining the adverse histologic effects of fluoroquinolones also were collected. Data Synthesis: A total of 175 papers, including 89 case reports and 8 literature reviews, were identified. Conclusions: Fluoroquinolone tendinopathy may not respond well to the current popular eccentric training regimes and may require an alternative, staged treatment approach. Clinicians, athletes, athletic trainers, and their medical support teams should be aware of the need to discuss and possibly discontinue these antibiotics if adverse effects arise. PMID:24762232

Application of a framework for extrapolating chemical effects ...

EPA Pesticide Factsheets

Cross-species extrapolation of toxicity data from limited surrogate test organisms to all wildlife with potential of chemical exposure remains a key challenge in ecological risk assessment. A number of factors affect extrapolation, including the chemical exposure, pharmacokinetics, life-stage, and pathway similarities/differences. Here we propose a framework using a tiered approach for species extrapolation that enables a transparent weight-of-evidence driven evaluation of pathway conservation (or lack thereof) in the context of adverse outcome pathways. Adverse outcome pathways describe the linkages from a molecular initiating event, defined as the chemical-biomolecule interaction, through subsequent key events leading to an adverse outcome of regulatory concern (e.g., mortality, reproductive dysfunction). Tier 1 of the extrapolation framework employs in silico evaluations of sequence and structural conservation of molecules (e.g., receptors, enzymes) associated with molecular initiating events or upstream key events. Such evaluations make use of available empirical and sequence data to assess taxonomic relevance. Tier 2 uses in vitro bioassays, such as enzyme inhibition/activation, competitive receptor binding, and transcriptional activation assays to explore functional conservation of pathways across taxa. Finally, Tier 3 provides a comparative analysis of in vivo responses between species utilizing well-established model organisms to assess departure from

Not afraid to blame: the neglected role of blame attribution in medical consumerism and some implications for health policy.

PubMed

Rosenthal, Marsha; Schlesinger, Mark

2002-01-01

A crucial aspect of medical consumerism has been overlooked in past research and policymaking: how consumers decide whom to "blame" for bad outcomes. This study explores how, in a system increasingly dominated by managed care, these attributions affect consumers' attitudes and behavior. Using data from the experiences of people with serious mental illness, hypotheses are tested regarding the origins and consequences of blaming for medical consumerism. Blame was allocated to health plans in a manner similar, but not identical, to the way in which blame was allocated to health care professionals. Both allocations are shaped by enrollment in managed care, with blame allocation affecting consumers' subsequent willingness to talk about adverse events. Policy implications include the need for more finely tuned grievance procedures and better consumer education about managed care practices.

Additively manufactured (AM) metal components often exhibit fine dendritic microstructures and elemental segregation due to the initial rapid solidification and subsequent melting and cooling during the build process, which without homogenization would adversely affect materials performance. In this letter, we report in situ observation of the homogenization kinetics of an AM nickel-based superalloy using synchrotron small angle X-ray scattering. The identified kinetic time scale is in good agreement with thermodynamic diffusion simulation predictions using microstructural dimensions acquired by ex situ scanning electron microscopy. These findings could serve as a recipe for predicting, observing, and validating homogenization treatments in AM materials.

A perpetual shortage of physical therapists qualified to provide home health care exists in Southern California. This paper presents one solution to the problem: the employment of a physical therapist assistant. The preparation, implementation, and evaluation of a program for employing a physical therapist assistant in a home health agency is presented and discussed. The use of the assistant increased the availability of physical therapy, and quality was not adversely affected. The assistant was accepted by staff and derived job satisfaction. We concluded that this assistant was a valuable adjunct to the home health team. Subsequently, The Visiting Nurse Association of Los Angeles employed two additional assistants in 1980.

Numerous definitions have been proposed for the diagnosis of myocardial infarction (MI) after coronary revascularization. The universal definition for MI designates post procedural biomarker thresholds for defining percutaneous coronary intervention (PCI)-related MI (type 4a) and coronary artery bypass grafting (CABG)-related MI (type 5) which are of uncertain prognostic importance. In addition, for both MI types cTn is recommended as the biomarker of choice, the prognostic significance of which is less well validated than CK-MB. Widespread adoption of a MI definition not clearly linked to subsequent adverse events such as mortality or heart failure may have serious consequences for the appropriate assessment of devices and therapies, may affect clinical care pathways, and may result in misinterpretation of physician competence. Rather than employing an MI definition sensitive for small degrees of myonecrosis (the occurrence of which, based on contemporary large-scale studies, are unlikely to have important clinical consequences), it is instead recommended that a threshold level of biomarker elevation which has been strongly linked to subsequent adverse events in clinical studies be used to define a "clinically relevant MI." The present document introduces a new definition for "clinically relevant MI" after coronary revascularization (PCI or CABG) which is applicable for use in clinical trials, patient care, and quality outcomes assessment.

70 years of radiation genetics: Fruit flies, mice and humans

1997-03-01

Radiation protection`s function is to protect society from the potential hazards that might occur through the human use of radiation, whether it be from energy production, medical uses or other sources of exposure. To do so, various scientific bodies are called upon to develop risk estimates which will provide society with adequate protection to the adverse effects of radiation, as best we can understand those adverse affects. Geneticists have the added burden, in that they must attempt to provide protection not only to the offspring of the present generation but also for all subsequent generations. While most of us havemore » difficulty in thinking of effects that might be manifest only one or two generations into the future, some have projected potential risks for 50 to 100 generations. Here the author reviews work on fruit flies and mice, and studies of human exposures, which has provided much of the foundational information upon which geneticists can derive conclusions with regard to radiation protection questions.« less

Environmental pollutants and lifestyle factors induce oxidative stress and poor prenatal development.

Developmental toxicity caused by exposure to a mixture of environmental pollutants has become a major health concern. Human-made chemicals, including xenoestrogens, pesticides and heavy metals, as well as unhealthy lifestyle behaviours, mainly tobacco smoking, alcohol consumption and medical drug abuse, are major factors that adversely influence prenatal development and increase susceptibility of offspring to diseases. There is evidence to suggest that the developmental toxicological mechanisms of chemicals and lifestyle factors involve the generation of reactive oxygen species (ROS) and cellular oxidative damage. Overproduction of ROS induces oxidative stress, a state where increased ROS generation overwhelms antioxidant protection and subsequently leads to oxidative damage of cellular macromolecules. Data on the involvement of oxidative stress in the mechanism of developmental toxicity following exposure to environmental pollutants are reviewed in an attempt to provide an updated basis for future studies on the toxic effect of such pollutants, particularly the notion of increased risk for developmental toxicity due to combined and cumulative exposure to various environmental pollutants. The aims of such studies are to better understand the mechanisms by which environmental pollutants adversely affect conceptus development and to elucidate the impact of cumulative exposures to multiple pollutants on post-natal development and health outcomes.

Direct but no transgenerational effects of decitabine and vorinostat on male fertility.

Establishment and maintenance of the correct epigenetic code is essential for a plethora of physiological pathways and disturbed epigenetic patterns can provoke severe consequences, e.g. tumour formation. In recent years, epigenetic drugs altering the epigenome of tumours actively have been developed for anti-cancer therapies. However, such drugs could potentially also affect other physiological pathways and systems in which intact epigenetic patterns are essential. Amongst those, male fertility is one of the most prominent. Consequently, we addressed possible direct effects of two epigenetic drugs, decitabine and vorinostat, on both, the male germ line and fertility. In addition, we checked for putative transgenerational epigenetic effects on the germ line of subsequent generations (F1-F3). Parental adult male C57Bl/6 mice were treated with either decitabine or vorinostat and analysed as well as three subsequent untreated generations derived from these males. Treatment directly affected several reproductive parameters as testis (decitabine & vorinostat) and epididymis weight, size of accessory sex glands (vorinostat), the height of the seminiferous epithelium and sperm concentration and morphology (decitabine). Furthermore, after decitabine administration, DNA methylation of a number of loci was altered in sperm. However, when analysing fertility of treated mice (fertilisation, litter size and sex ratio), no major effect of the selected epigenetic drugs on male fertility was detected. In subsequent generations (F1-F3 generations) only subtle changes on reproductive organs, sperm parameters and DNA methylation but no overall effect on fertility was observed. Consequently, in mice, decitabine and vorinostat neither affected male fertility per se nor caused marked transgenerational effects. We therefore suggest that both drugs do not induce major adverse effects-in terms of male fertility and transgenerational epigenetic inheritance-when used in anti-cancer-therapies.

The relationship between early adversity and numerous negative outcomes across the lifespan is evident in a wide range of societies and cultures (e.g., Pakulak, Stevens, & Neville, 2018). Among the most affected neural systems are those supporting attention, self-regulation, and stress regulation. As such, these systems represent targets for neurobiologically informed interventions addressing early adversity. In prior work with monolingual native English-speaking families, we showed that a two-generation intervention targeting these systems in families improves outcomes across multiple domains including child brain function for selective attention (for detail, see Neville et al., 2013). Here, we discuss the translation and cultural adaptation (CA) of this intervention in local and international contexts, which required systematic consideration of cultural differences that could affect program acceptability. First, we conducted a translation and CA of our program to serve Latino families in the United States using the Cultural Adaptation Process (CAP), a model that works closely with stakeholders in a systematic, iterative process. Second, to implement the adapted program in Medellín, Colombia, we conducted a subsequent adaptation for Colombian culture using the same CAP. Our experience underscores the importance of consideration of cultural differences and a systematic approach to adaptation before assessing the efficacy of neurobiologically informed interventions in different cultural contexts. © 2017 Wiley Periodicals, Inc.

Ankylosing Spondylitis and Pregnancy: A Literature Review.

2017-01-01

Ankylosing Spondylitis (AS) is the prototype of a group of systemic rheumatic diseases collectively referred to as Spondylarthitides (SpA). It has now become clear that AS is not as rare as previously thought and, although it has an early onset in life affecting patients in their reproductive years, it has not been proved to adversely affect fertility in females. The aim of this review is to summarize all the recent data on AS and pregnancy in terms of fertility, disease course and pregnancy outcome from a clinical perspective. A literature research was conducted based on the following medical databases: Pubmed/ Medline and the Cochrane Library. We searched for randomized controlled studies, casecontrol studies, cohort studies, patient and drug registers in relation to pregnancy and AS. The existing data do not support a causal relationship between AS and infertility. The state of pregnancy is not associated with reduced disease activity in patients with AS. Additionally, AS tends to adversely affect health-related quality of life during pregnancy, in comparison with normal population and patients with rheumatoid arthritis. As far as the obstetrical outcome is concerned, there is no consensus on the significant association between AS and specific pregnancy, delivery and fetal complications. Previous studies are highly heterogenous and mainly retrospective and thus, the existing data are controversial and inconclusive. Subsequent studies are required to enlighten our knowledge on the interaction between AS and pregnancy.

Mixing implants with differing metallic compositions has been avoided for fear of galvanic corrosion and subsequent failure of the implants and of bone healing. The purpose of this study was to evaluate upper-extremity fractures treated with open reduction and internal fixation with metallic implants that differed in metallic composition placed on the same bone. The authors studied the effects of using both stainless steel and titanium implants on fracture healing, implant failure, and other complications associated with this method of fixation. Their hypothesis was that combining these metals on the same bone would not cause clinically significant nonunions or undo clinical effects from galvanic corrosion. A retrospective review was performed of 17 patients with upper-extremity fractures fixed with metal implants of differing metallic compositions. The primary endpoint was fracture union. Eight clavicles, 2 proximal humeri, 3 distal humeri, 3 olecranons, and 1 glenoid fracture with an average follow-up 10 months were reviewed. All fractures healed. One patient experienced screw backout, which did not affect healing. This study implies that mixing implants with differing metallic compositions on the same bone for the treatment of fractures does not adversely affect bone healing. No evidence existed of corrosion or an increase in complications with this method of treatment. Contrary to prior belief, small modular hand stainless steel plates can be used to assist in reduction of smaller fracture fragments in combination with anatomic titanium plates to obtain anatomic reduction of the fracture without adversely affecting healing.

Although several studies have shown that life adversities play an important role in the etiology and maintenance of both depressive and anxiety disorders, little is known about the relative specificity of several types of life adversities to different forms of depressive and anxiety disorder and the concurrent role of neuroticism. Few studies have investigated whether clustering of life adversities or comorbidity of psychiatric disorders critically influence these relationships. Using data from the Netherlands Study of Depression and Anxiety (NESDA), we analyzed the association of childhood adversities and negative life experiences across the lifespan with lifetime DSM-IV-based diagnoses of depression or anxiety among 2288 participants with at least one affective disorder. Controlling for comorbidity and clustering of adversities the association of childhood adversity with affective disorders was greater than that of negative life events across the life span with affective disorders. Among childhood adversities, emotional neglect was specifically associated with depressive disorder, dysthymia, and social phobia. Persons with a history of emotional neglect and sexual abuse were more likely to develop more than one lifetime affective disorder. Neuroticism and current affective disorder did not affect the adversity-disorder relationships found. Using a retrospective study design, causal interpretations of the relationships found are not warranted. Emotional neglect seems to be differentially related to depression, dysthymia and social phobia. This knowledge may help to reduce underestimation of the impact of emotional abuse and lead to better recognition and treatment to prevent long-term disorders. Copyright 2010 Elsevier B.V.

Di-methyl phthalate (DMP), a typical endocrine disrupting chemical (EDC), is ubiquitously distributed in aquatic environments; yet studies regarding its impact on gametes and the resulting effects on embryogenesis in marine gastropods are relatively scarce. In this study, the influences of DMP on the gametes and subsequent developmental process of abalone (Haliotis diversicolor supertexta, a representative marine benthic gastropod) were assessed. Newborn abalone eggs and sperm were exposed separately to different DMP concentrations (1, 10 or 100 ppb) for 60 min. At the end-point of exposure, the DMP-treated eggs and sperm were collected for analysis of their ultra-structures, ATPase activities and total lipid levels, and the fertilized gametes (embryos) were collected to monitor related reproductive parameters (fertilization rate, abnormal development rate and hatching success rate). Treatment with DMP did not significantly alter the structure or total lipid content of eggs at any of the doses tested. Hatching failures and morphological abnormalities were only observed with the highest dose of DMP (100 ppb). However, DMP exposure did suppress sperm ATPase activities and affect the morphological character of their mitochondria. DMP-treated sperm exhibited dose-dependent decreases in fertilization efficiency, morphogenesis and hatchability. Relatively obvious toxicological effects were observed when both sperm and eggs were exposed to DMP. Furthermore, RT-PCR results indicate that treatment of gametes with DMP changed the expression patterns of physiologically-regulated genes (cyp3a, 17β-HSD-11 and 17β-HSD-12) in subsequent embryogenesis. Taken together, this study proofed that pre-fertilization exposure of abalone eggs, sperm or both to DMP adversely affects the fertilization process and subsequent embryogenesis. PMID:22028799

In addition to the very complex risks, hazards potentially lead to disasters in the oil and gas projects. These risks can certainly be anticipated with the application of risk management, but an unsystematic and ineffective implementation of risk management will still bring adverse impacts. According to the eleven risk management principles in ISO 31000:2009, the application of risk management must pay attention to all aspects, both internal and external factors. Thus, this paper aims to identify variables that could affect the disaster mitigation efforts of oil and gas projects. This research began with literature study to determine the problems of risk management in oil and gas projects, so the affecting variables as the study objectives can be specified subsequently based on the literature review as well. The variables that must be considered in the efforts of disaster risk mitigation of oil and gas project are the risk factors and sustainability aspect.

Deconstructing fatalism: ethnographic perspectives on women's decision making about cancer prevention and treatment.

PubMed

Drew, Elaine M; Schoenberg, Nancy E

2011-06-01

Researchers have long held that fatalism (the belief in a lack of personal power or control over destiny or fate) constitutes a major barrier to participation in positive health behaviors and, subsequently, adversely affects health outcomes. In this article, we present two in-depth, ethnographic studies of rural women's health decisions surrounding cancer treatments to illustrate the complexity and contestability of the long-established fatalism construct. Narrative analyses suggest that for these women, numerous and complex factors--including inadequate access to health services, a legacy of self-reliance, insufficient privacy, combined with a culturally acceptable idiom of fatalism--foster the use of, but not necessarily a rigid conviction in, the notion of fatalism.

Environmental exposures to agrochemicals in the Sierra Nevada mountain range

The release of pesticides into the environment may impact human and environmental health. Despite the need for environmental exposure data, few studies quantify exposures in urban areas and even fewer determine exposures to wildlife in remote areas. Although it is expected that concentrations in remote regions will be low, recent studies suggest that even low concentrations may have deleterious effects on wildlife. Many pesticides are known to interfere with the endocrine systems of humans and wildlife, adversely affecting growth, development, and behavior. This chapter reviews the fate and transport of pesticides applied in the Central Valley of California and quantifies their subsequent deposition into the relatively pristine Sierra Nevada Mountain Range.

Peroxidase-catalyzed removal of phenols from a petroleum refinery wastewater.

Wagner, M; Nicell, J A

2001-01-01

The phenol content of a petroleum refinery wastewater was reduced below the discharge limit following treatment with horseradish peroxidase and H2O2. Approximately 58% of COD, 78% of BOD5, and 95% of toxicity were removed along with the phenols. As a result of treatment, phenols were transformed into less biodegradable compounds which could be removed by subsequent coagulation and precipitation. Optimization of the peroxide concentration led to 20% enzyme savings. The use of PEG and chitosan as protective additives resulted in 4 and 25-fold reductions in enzyme requirements, respectively. Phenol removal did not appear to be adversely affected by the presence of other hydrocarbons that are frequently present in refinery wastewaters.

Linking Adverse Childhood Effects and Attachment: A Theory of Etiology for Sexual Offending.

Grady, Melissa D; Levenson, Jill S; Bolder, Tess

2016-01-25

Sexual violence continues to be a significant public health problem affecting significant portions of the population. Unfortunately, an agreed upon theory of etiology remains elusive leading to challenges in developing effective prevention and treatment interventions. Recently, there is a growing body of literature examining the role of adverse childhood experiences (ACEs) in the development of sexually violent behavior. This research has begun to explore the rates of various types of child maltreatments and family dysfunction in individuals who have been convicted of a sexual crime. These empirical inquiries have been primarily descriptive in nature and have not yet provided a cohesive theoretical model as to why the presence of ACEs might contribute to sexually abusive behavior. This article suggests that attachment theory offers an explanatory link between early adversity and sexually abusive behavior in adulthood. We first summarize important attachment theory concepts, then integrate them with research in the area of developmental psychopathology and ACEs, and finally propose a model by which attachment can be used as an explanatory theory for subsequent sexualized coping and sexually abusive behaviors. Finally, this article explores the implications for practice, policy, and research using this explanatory theory as a framework for understanding sexual violence. © The Author(s) 2016.

Recent increases in fructose consumption have raised concerns regarding the potential adverse intergenerational effects, as maternal fructose intake may induce physiological dysfunction in offspring. However, no reports are available regarding the effect of excess maternal fructose on reproductive tissues such as the ovary. Notably, the maternal intrauterine environment has been demonstrated to affect ovarian development in the subsequent generation. Given the fructose is transferred to the fetus, excess fructose consumption may affect offspring ovarian development. As ovarian development and its function is maintained by 17β-estradiol, we therefore investigated whether excess maternal fructose intake influences offspring ovarian estradiol synthesis. Rats received a 20% fructose solution during gestation and lactation. After weaning, offspring ovaries were isolated. Offspring from fructose-fed dams showed reduced StAR and P450(17α) mRNA levels, along with decreased protein expression levels. Conversely, attenuated P450arom protein level was found in the absence of mRNA expression alteration. Consistent with these phenomena, decreased circulating levels of estradiol were observed. Furthermore, estrogen receptor α (ERα) protein levels were also down-regulated. In accordance, the mRNA for progesterone receptor, a transcriptional target of ERα, was decreased. These results suggest that maternal fructose might alter ovarian physiology in the subsequent generation. Copyright © 2018 Elsevier Inc. All rights reserved.

Consideration of a new definition of clinically relevant myocardial infarction after coronary revascularization: an expert consensus document from the Society for Cardiovascular Angiography and Interventions (SCAI).

Numerous definitions have been proposed for the diagnosis of myocardial infarction (MI) after coronary revascularization. The universal definition for MI designates post procedural biomarker thresholds for defining percutaneous coronary intervention (PCI)-related MI (type 4a) and coronary artery bypass grafting (CABG)-related MI (type 5), which are of uncertain prognostic importance. In addition, for both the MI types, cTn is recommended as the biomarker of choice, the prognostic significance of which is less well validated than CK-MB. Widespread adoption of a MI definition not clearly linked to subsequent adverse events such as mortality or heart failure may have serious consequences for the appropriate assessment of devices and therapies, may affect clinical care pathways, and may result in misinterpretation of physician competence. Rather than using an MI definition sensitive for small degrees of myonecrosis (the occurrence of which, based on contemporary large-scale studies, are unlikely to have important clinical consequences), it is instead recommended that a threshold level of biomarker elevation which has been strongly linked to subsequent adverse events in clinical studies be used to define a "clinically relevant MI." The present document introduces a new definition for "clinically relevant MI" after coronary revascularization (PCI or CABG), which is applicable for use in clinical trials, patient care, and quality outcomes assessment.

Laboratory toxicity studies demonstrate no adverse effects of Cry1Ab and Cry3Bb1 to larvae of Adalia bipunctata (Coleoptera: Coccinellidae): the importance of study design.

PubMed

Alvarez-Alfageme, Fernando; Bigler, Franz; Romeis, Jörg

2011-06-01

Scientific studies are frequently used to support policy decisions related to transgenic crops. Schmidt et al., Arch Environ Contam Toxicol 56:221-228 (2009) recently reported that Cry1Ab and Cry3Bb were toxic to larvae of Adalia bipunctata in direct feeding studies. This study was quoted, among others, to justify the ban of Bt maize (MON 810) in Germany. The study has subsequently been criticized because of methodological shortcomings that make it questionable whether the observed effects were due to direct toxicity of the two Cry proteins. We therefore conducted tritrophic studies assessing whether an effect of the two proteins on A. bipunctata could be detected under more realistic routes of exposure. Spider mites that had fed on Bt maize (events MON810 and MON88017) were used as carriers to expose young A. bipunctata larvae to high doses of biologically active Cry1Ab and Cry3Bb1. Ingestion of the two Cry proteins by A. bipunctata did not affect larval mortality, weight, or development time. These results were confirmed in a subsequent experiment in which A. bipunctata were directly fed with a sucrose solution containing dissolved purified proteins at concentrations approximately 10 times higher than measured in Bt maize-fed spider mites. Hence, our study does not provide any evidence that larvae of A. bipunctata are sensitive to Cry1Ab and Cry3Bb1 or that Bt maize expressing these proteins would adversely affect this predator. The results suggest that the apparent harmful effects of Cry1Ab and Cry3Bb1 reported by Schmidt et al., Arch Environ Contam Toxicol 56:221-228 (2009) were artifacts of poor study design and procedures. It is thus important that decision-makers evaluate the quality of individual scientific studies and do not view all as equally rigorous and relevant.

The high rate of the sudden infant death syndrome (SIDS) in American Indians in the Northern Plains (3.5/1000) may reflect the high incidence of cigarette smoking and alcohol consumption during pregnancy. Nicotine, a neurotoxic component of cigarettes, and alcohol adversely affect nicotinic receptor binding and subsequent cholinergic development in animals. We measured (3)H-nicotine receptor binding in 16 brainstem nuclei in American Indian SIDS (n = 27) and controls (n = 6). In five nuclei related to cardiorespiratory control, (3)H-nicotinic binding decreased with increasing number of drinks (P < 0.03). There were no differences in binding in SIDS compared with controls, except upon stratification of prenatal exposures. In three mesopontine nuclei critical for arousal there were reductions (P < 0.04) in binding in controls exposed to cigarette smoke compared with controls without exposure; there was no difference between SIDS cases with or without exposure. This study suggests that maternal smoking and alcohol affects (3)H-nicotinic binding in the infant brainstem irrespective of the cause of death. It also suggests that SIDS cases are unable to respond to maternal smoking with the "normal" reduction seen in controls. Future studies are needed to establish the role of adverse prenatal exposures in altered brainstem neurochemistry in SIDS.

Objective The Trans Pacific Partnership Agreement (TPP) is a recently concluded free trade agreement involving Australia and 11 other Pacific-rim nations, which has the potential for far-reaching impacts on public health. A health impact assessment (HIA) was carried out during the negotiations to determine the potential future public health impact in Australia and to provide recommendations to mitigate potential harms. This paper explores the findings and outcomes of the HIA, and how this approach can be used to provide evidence for public health advocacy. Design A modified version of the standard HIA process was followed. The HIA was led by technical experts in HIA, trade policy, and health policy, in collaboration with advocacy organisations concerned with the TPP and health. The HIA reviewed the provisions in leaked TPP text in order to determine their potential impact on future health policy. As part of this process, researchers developed policy scenarios in order to examine how TPP provisions may affect health policies and their subsequent impact to health for both the general and vulnerable populations. The four policy areas assessed were the cost of medicines, tobacco control, alcohol control and food labelling. Results In all areas assessed, the HIA found that proposed TPP provisions were likely to adversely affect health. These provisions are also likely to more adversely affect the health of vulnerable populations. Conclusions The HIA produced relevant evidence that was useful in advocacy efforts by stakeholders, and engaging the public through various media platforms. PMID:27044579

The aim of this study was to evaluate the rate of intraoperative and postoperative complications in a large series of patients affected by neuromuscular scoliosis. It was a monocentric retrospective study. In this study have been considered complications those events that significantly affected the course of treatment, such as getting the hospital stay longer, or requiring a subsequent surgical procedure, or corrupting the final result of the treatment. Of the 358 patients affected by neuromuscular scoliosis treated from January 1985 to December 2010, 185 that met the inclusion criteria were included in the study. There were recorded 66 complications in 55/185 patients. Of that 66 complications, 54 complications occurred in 46/120 patients with Luque's instrumentation, while only 12 complications occurred in 9/65 patients with hybrid instrumentation and this difference was statistically significant (p < 0.05); 11/126 patients with pelvic fixation and 5/59 without pelvic fixation, as well as 45/156 patients treated by posterior approach alone and 10/29 patient that underwent combined anterior-posterior approach suffered complications but both this did not result in a statistical significant difference (p > 0.05). The surgical treatment in neuromuscular scoliosis is burdened by a large number of complications. An accurate knowledge of possible complications is mandatory to prepare strategies due to prevent adverse events. A difference in definitions could completely change results in good or bad as well as in our same series the adverse events amounted at almost 30% of cases, but complications that due to complete failure would amount at 9.19% of patients.

Adverse effects of meglumine diatrizoate on renal function in the early post-transplant period.

Thirty-four renal transplant recipients received drip infusion urograms from 2-24 days post-transplantation. Twenty-two patients exhibited changes in renal function within 1-4 days of the urogram that were indistinguishable from allograft rejection: a tender, swollen kidney, elevation of serum creatinine, oliguria, decreased urine sodium concentration, weight gain, and hypertension. Two patients developed acute tubular necrosis and required hemodialysis, but renal function in the remaining 20 patients improved after therapy for "graft rejection" with i.v. methyprednisolone sodium succinnate. Kidneys from older-age donors that were functioning suboptimally and kidneys which exhibited subsequent clinical allograft rejection were more at risk for contrast media toxicity. This suggests that occult vascular lesions may have been present in the allograft which were exacerbated when exposed to the irritant vascular effects of contrast media, producing a mild, reversible toxic nephritis. However, several kidneys with normal function and several kidneys which never exhibited rejection activity were also adversely affected by exposure to contrast media. It appears these agents should be used cautiously, if at all, in the early post-transplant period.

Azolla filiculoides Nitrogenase Activity Decrease Induced by Inoculation with Chlamydomonas sp. †

Experiments were conducted to determine the influence of Chlamydomonas sp. on nitrogen fixation (C2H2 → C2H4) in Azolla filiculoides and on the nitrogen fixation and growth of free-living Anabaena azollae 2B organisms. Inoculation of azolla medium with Chlamydomonas sp. was associated with decreased nitrogenase activity in A. filiculoides and with increases in the density of a fungal population identified as Acremonium sp. Subsequent inoculation of azolla medium with this fungus was also accompanied by a significant decrease in nitrogenase activity of A. filiculoides. However, the extent of depression of nitrogenase activity was significantly higher when azolla medium was inoculated with Chlamydomonas sp. than when it was inoculated with Acremonium sp. Inoculation of nitrogen-free Stanier medium with either Acremonium sp. or Chlamydomonas sp. did not adversely affect the growth or nitrogenase activity of free-living A. azollae. Decreased nitrogenase activity in A. filiculoides is apparently related to the adverse influence of the green alga and the fungus on the macrosymbiont. The mechanisms that might be involved are discussed. PMID:16347211

Early-life programming of susceptibility to dysregulation of glucose metabolism and the development of Type 2 diabetes mellitus.

Holness, M J; Langdown, M L; Sugden, M C

2000-01-01

There is increasing epidemiological evidence in humans which associates low birthweight with later metabolic disorders, including insulin resistance and glucose intolerance. There is evidence that nutritional and hormonal factors (e.g. maternal protein restriction, exposure to excess maternal glucocorticoids) markedly influence intra-uterine growth and development. A picture is also emerging of the biochemical and physiological mechanisms that may underlie these effects. This review focuses on recent research directed towards understanding the molecular basis of the relationship between indices of poor early growth and the subsequent development of glucose intolerance and Type 2 diabetes mellitus using animal models that attempt to recreate the process of programming via an adverse intra-uterine or neonatal environment. Emphasis is on the chain of events and potential mechanisms by which adverse adaptations affect pancreatic-beta-cell insulin secretion and the sensitivity to insulin of key metabolic processes, including hepatic glucose production, skeletal-muscle glucose disposal and adipose-tissue lipolysis. Unravelling the molecular details involved in metabolic programming may provide new insights into the pathogenesis of impaired glucoregulation and Type 2 diabetes. PMID:10903125

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.

High-level sport can be analyzed using the complex system model, in which performance is constrained by many factors. Coaches' and athletes' perceptions of important positive and negative factors affecting performance were compared. Participants were 48 high-level international triathletes (n = 34) and their coaches (n = 14). They were personally interviewed via a questionnaire designed by four accredited experts, who selected groups of both positive and negative factors affecting performance. A list of factors was developed, in order of greater to lesser importance in the opinion of athletes and coaches, for subsequent analysis. Two ranked lists (positive and negative factors) indicated that athletes appear to rate personal environment factors (family, teammates, lack of support from relatives) higher, while the coaches tended to give more importance to technical and institutional aspects (institutional support, coach, medical support). There was complete agreement between coaches and triathletes about the top five positive factors. Negative factor agreement was somewhat lower (agreement on 3/5 factors). The most important positive factor for coaches and athletes was "dedication/engagement," while the most important factor adversely affecting performance was "injuries".

Negative (but not Positive) Parenting Interacts with Infant Negative Affect to Predict Infant Approach: Evidence of Diathesis-Stress.

Temperament by parenting interactions may reflect that individuals with greater risk are more likely to experience negative outcomes in adverse contexts (diathesis-stress) or that these individuals are more susceptible to contextual influences in a 'for better or for worse' pattern (differential susceptibility). Although such interactions have been identified for a variety of child outcomes, prior research has not examined approach characteristics - excitement and approach toward pleasurable activities - in the first year of life. Therefore, the current study investigated whether 6-month maternal reported infant negative affect - a phenotypic marker of risk/susceptibility - interacted with 8-month observed parenting behaviors (positive parenting, negative parenting) to predict 12-month infant behavioral approach. Based a sample of mothers and their infants ( N =150), results indicated that negative parenting was inversely associated with subsequent approach for infants with high, but not low, levels of early negative affect. Similar results did not occur regarding positive parenting. These findings better fit a diathesis-stress model rather than a differential susceptibility model. Implications and limitations of these findings are discussed.

A winter storm that crossed the continental United States in mid-February 1990 produced hazardous weather across a vast area of the nation. A wide range of severe weather was reported, including heavy snowfall; freezing rain and drizzle; thunderstorms with destructive winds, lightning, large hail, and tornadoes; prolonged heavy rain with subsequent flooding; frost damage to citrus orchards; and sustained destructive winds not associated with thunderstorms. Low-end preliminary estimates of impacts included 9 deaths, 27 injuries, and $120 million of property damage. At least 35 states and southeastern Canada were adversely affected. The storm occurred during the field operations of four independent atmospheric research projects that obtained special, detailed observations of it from the Rocky Mountains to the eastern great Lakes.

Effect of crude protein concentration and dietary electrolyte balance on litter quality, foot pad dermatitis, growth performance and processing yields in two medium heavy turkey hybrids.

1. An experiment was conducted to investigate the effect of crude protein (CP) concentration and dietary electrolyte balance (DEB) on growth performance, processing yields, litter quality and foot pad dermatitis (FPD) in male turkeys from two commercial hybrids. Soya bean meal was replaced by vegetable protein sources selected for lower K concentrations to lower DEB in order to improve litter quality and subsequent quality of foot pads. 2. Effects of CP on litter friability and wetness were not consistent during the production period. FPD in turkeys fed on diets with low CP was significantly lower than FPD in turkeys fed on diets with high CP until 84 d. Growth performance was adversely affected at low CP. Processing yields were not affected by CP. 3. Litter was significantly dryer in pens of turkeys fed on diets with low DEB than in pens of turkeys fed on diets with high DEB. FPD in turkeys fed on diets with low DEB was significantly lower than in turkeys fed on diets with high DEB. Growth performance and processing yields were adversely affected at low DEB. 4. FPD in turkey hybrid A was higher than in turkey hybrid B at 28 d of age. Thereafter, no differences in FPD between turkey hybrids were observed. Growth performance and processing yields were not affected by turkey hybrid. 5. Overall, a significant interaction effect of CP × DEB was observed for FCR: in turkeys fed on the high DEB treatment, FCR of turkeys fed on the high CP diets was lower than FCR of turkeys fed on the low CP (LCP) diets whereas on the low DEB treatment, FCR was not affected by CP treatment. 6. It was concluded that litter quality can be improved and FPD may be decreased in turkeys fed on diets containing lower CP and DEB levels.

Baseline Hemodynamics and Response to Contrast Media During Diagnostic Cardiac Catheterization Predict Adverse Events in Heart Failure Patients.

Contrast media administered during cardiac catheterization can affect hemodynamic variables. However, little is documented about the effects of contrast on hemodynamics in heart failure patients or the prognostic value of baseline and changes in hemodynamics for predicting subsequent adverse events. In this prospective study of 150 heart failure patients, we measured hemodynamics at baseline and after administration of iodixanol or iopamidol contrast. One-year Kaplan-Meier estimates of adverse event-free survival (death, heart failure hospitalization, and rehospitalization) were generated, grouping patients by baseline measures of pulmonary capillary wedge pressure (PCWP) and cardiac index (CI), and by changes in those measures after contrast administration. We used Cox proportional hazards modeling to assess sequentially adding baseline PCWP and change in CI to 5 validated risk models (Seattle Heart Failure Score, ESCAPE [Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness], CHARM [Candesartan in Heart Failure: Assessment of Reduction in Mortality and Morbidity], CORONA [Controlled Rosuvastatin Multinational Trial in Heart Failure], and MAGGIC [Meta-Analysis Global Group in Chronic Heart Failure]). Median contrast volume was 109 mL. Both contrast media caused similarly small but statistically significant changes in most hemodynamic variables. There were 39 adverse events (26.0%). Adverse event rates increased using the composite metric of baseline PCWP and change in CI (P<0.01); elevated baseline PCWP and decreased CI after contrast correlated with the poorest prognosis. Adding both baseline PCWP and change in CI to the 5 risk models universally improved their predictive value (P≤0.02). In heart failure patients, the administration of contrast causes small but significant changes in hemodynamics. Calculating baseline PCWP with change in CI after contrast predicts adverse events and increases the predictive value of existing models. Patients with elevated baseline PCWP and decreased CI after contrast merit greatest concern. © 2016 American Heart Association, Inc.

Disaster studies have documented that both post-traumatic stress disorder (PTSD) and depression develop during the first six months following disaster exposure for the majority of those afflicted. and Using data from 325 tsunami-affected families living in southern Sri Lanka, the current study investigates whether community social resources such as residents' perceived community participation in tsunami recovery efforts reduce mental health risks (PTSD and depressive symptoms) of tsunami-affected mothers. The analysis is based on structural equation modelling. and The findings of structural equation modelling supports the main hypothesis that residents' perceived community participation directly and indirectly (through collective family functioning and mental health service use) reduces mental health risks (both PTSD and depressive symptoms) of tsunami-affected mothers after controlling for pre-tsunami family adversities. In addition, the results show that residents' perceived community participation buffers the influence of trauma exposure on PTSD symptom levels of mothers. The identification of specific social and family processes that relate to mental health can be useful for post-disaster interventions and recovery programmes.

Gene–environment interplay in Drosophila melanogaster: Chronic food deprivation in early life affects adult exploratory and fitness traits

Early life adversity has known impacts on adult health and behavior, yet little is known about the gene–environment interactions (GEIs) that underlie these consequences. We used the fruit fly Drosophila melanogaster to show that chronic early nutritional adversity interacts with rover and sitter allelic variants of foraging (for) to affect adult exploratory behavior, a phenotype that is critical for foraging, and reproductive fitness. Chronic nutritional adversity during adulthood did not affect rover or sitter adult exploratory behavior; however, early nutritional adversity in the larval period increased sitter but not rover adult exploratory behavior. Increasing for gene expression in the mushroom bodies, an important center of integration in the fly brain, changed the amount of exploratory behavior exhibited by sitter adults when they did not experience early nutritional adversity but had no effect in sitters that experienced early nutritional adversity. Manipulation of the larval nutritional environment also affected adult reproductive output of sitters but not rovers, indicating GEIs on fitness itself. The natural for variants are an excellent model to examine how GEIs underlie the biological embedding of early experience. PMID:23045644

Do Holocaust survivors show increased vulnerability or resilience to post-Holocaust cumulative adversity?

PubMed

Shrira, Amit; Palgi, Yuval; Ben-Ezra, Menachem; Shmotkin, Dov

2010-06-01

Prior trauma can hinder coping with additional adversity or inoculate against the effect of recurrent adversity. The present study further addressed this issue by examining whether a subsample of Holocaust survivors and comparison groups, drawn from the Israeli component of the Survey of Health, Ageing, and Retirement in Europe, were differentially affected by post-Holocaust cumulative adversity. Post-Holocaust cumulative adversity had a stronger effect on the lifetime depression of Holocaust survivors than on that of comparisons. However, comparisons were more negatively affected by post-Holocaust cumulative adversity when examining markers of physical and cognitive functioning. Our findings suggest that previous trauma can both sensitize and immunize, as Holocaust survivors show general resilience intertwined with specific vulnerability when confronted with additional cumulative adversity.

Adversity during early development has been shown to have enduring negative physiological consequences. In turn, atypical physiological functioning has been associated with maladaptive processing of negative affect, including its regulation. The present study therefore explored whether exposure to adverse life events in childhood predicted maladaptive (less flexible) parasympathetic nervous system functioning during the processing of negative affect among adolescents with depression histories. An initially clinic-referred, pediatric sample (N=189) was assessed at two time points. At Time 1, when subjects were 10.17years old (SD=1.42), on average, and were depressed, parents reported on adverse life events the offspring experienced up to that point. At Time 2, when subjects were 17.18years old (SD=1.28), and were remitted from depression, parents again reported on adverse life events in their offspring's lives for the interim period. At time 2, subjects' parasympathetic nervous system functioning (quantified as respiratory sinus arrhythmia) also was assessed at rest, during sad mood induction, and during instructed mood repair. Extent of adverse life events experienced by T1 (but not events occurring between T1 and T2) predicted less flexible RSA functioning 7years later during the processing of negative affect. Adolescents with more extensive early life adversities exhibited less vagal withdrawal following negative mood induction and tended to show less physiological recovery following mood repair. Early adversities appear to be associated with less flexible physiological regulatory control during negative affect experience, when measured later in development. Stress-related autonomic dysfunction in vulnerable youths may contribute to the unfavorable clinical prognosis associated with juvenile-onset depression. Copyright © 2017 Elsevier B.V.

2014-05-01

Previously reported complications in medial opening wedge (MOW) high tibial osteotomy (HTO) vary considerably in both rate and severity. (1) To determine the rates of adverse events in MOW HTO classified into different grades of severity based on the treatments required and (2) to compare patient-reported outcomes between the different adverse event classifications. Case series; Level of evidence, 4. All patients receiving MOW HTO at a single medical center from 2005 to 2009 were included. Internal fixation was used in all cases, with either a nonlocking (Puddu) or locking (Tomofix) plate. Patients were evaluated at 2, 6, and 12 weeks; 6 and 12 months; and annually thereafter. Types of potential surgical and postoperative adverse events, categorized into 3 classes of severity based on the subsequent treatments, were defined a priori. Medical records and radiographs were then reviewed by an independent observer. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores were compared in subgroups of patients based on the categories of adverse events observed. A total of 323 consecutive procedures (242 males) were evaluated (age, mean ± standard deviation, 46 ± 9 years; body mass index, mean ± standard deviation, 30 ± 5 kg/m(2)). Adverse events requiring no additional treatment (class 1) were undisplaced lateral cortical breaches (20%), displaced (>2 mm) lateral hinge fracture (6%), delayed wound healing (6%), undisplaced lateral tibial plateau fracture (3%), hematoma (3%), and increased tibial slope ≥10° (1%). Adverse events requiring additional or extended nonoperative management (class 2) were delayed union (12%), cellulitis (10%), limited hardware failure (1 broken screw; 4%), postoperative stiffness (1%), deep vein thrombosis (1%), and complex regional pain syndrome (CRPS) type 1 (1%). Adverse events requiring additional or revision surgery and/or long-term medical care (class 3) were aseptic nonunion (3%), deep infection (2%), CRPS type 2 (1%), and severe hardware failure with loss of correction (1%). Additional surgery rate was 3%. Class 1 and 2 adverse events did not affect patient-reported outcomes at 6, 12, or 24 months postoperatively. Patients with class 3 adverse events had significantly lower total WOMAC scores at 6 months but not at 12 or 24 months postoperatively. The most common adverse event in MOW HTO requiring extended nonoperative treatment (class 2) is delayed union (12%). The rate of severe adverse events requiring additional surgery and/or long-term medical care (class 3) is low (7%).

Witnessing domestic violence during childhood is associated with psychopathic traits in adult male criminal offenders

PubMed Central

Dargis, Monika; Koenigs, Michael

2017-01-01

While there is growing evidence that suffering physical abuse during childhood is subsequently associated with psychopathic traits in both juvenile and adult offenders, there is considerably less research on whether exposure to domestic violence as a witness, rather than as a direct victim, influences the subsequent presentation of psychopathic traits in adulthood. Accordingly, the current study examined the relationship between witnessing domestic violence during childhood (i.e., witnessing, hearing, or intervening in abuse against a parent/sibling) and psychopathic traits in adulthood in a sample of n = 127 incarcerated male offenders. As predicted, witnessing domestic violence was significantly associated with overall level of psychopathy, with a particularly strong relationship to the interpersonal/affective features of psychopathy. Importantly, this relationship held when controlling for the experience of domestic violence as a direct victim. These results add to the growing body of literature linking adverse and traumatic events during childhood with psychopathic traits later in life, and suggest that domestic violence exposure may be one factor contributing to the manipulative, interpersonal style exhibited by individuals high in psychopathy.

Non-communicable diseases (NCDs) are a major cause of premature mortality. Recent studies show that predispositions for NCDs may arise from early-life exposure to low concentrations of environmental contaminants. This developmental origins of health and disease (DOHaD) paradigm suggests that programming of an embryo can be disrupted, changing the homeostatic set point of biological functions. Epigenetic alterations are a possible underlying mechanism. Here, we investigated the DOHaD paradigm by exposing zebrafish to subtoxic concentrations of the ubiquitous contaminant cadmium during embryogenesis, followed by growth under normal conditions. Prolonged behavioral responses to physical stress and altered antioxidative physiology were observed approximately ten weeks after termination of embryonal exposure, at concentrations that were 50-3200-fold below the direct embryotoxic concentration, and interpreted as altered developmental programming. Literature was explored for possible mechanistic pathways that link embryonic subtoxic cadmium to the observed apical phenotypes, more specifically, the probability of molecular mechanisms induced by cadmium exposure leading to altered DNA methylation and subsequently to the observed apical phenotypes. This was done using the adverse outcome pathway model framework, and assessing key event relationship plausibility by tailored Bradford-Hill analysis. Thus, cadmium interaction with thiols appeared to be the major contributor to late-life effects. Cadmium-thiol interactions may lead to depletion of the methyl donor S -adenosyl-methionine, resulting in methylome alterations, and may, additionally, result in oxidative stress, which may lead to DNA oxidation, and subsequently altered DNA methyltransferase activity. In this way, DNA methylation may be affected at a critical developmental stage, causing the observed apical phenotypes.

Patients with Parkinson disease (PD) commonly experience motor fluctuations and dyskinesias in response to oral dopaminergic medications. Affected patients may benefit from device-assisted therapy, such as medication infusion or deep brain stimulation surgery. This is the first Australian study of the long-term adherence to apomorphine infusion (AI) in patients with PD. To assess the adherence to AI in patients with PD in a single centre over a 10-year period and to find the reasons for discontinuation in patients who discontinued AI. This is an observational study of patients with PD treated with AI between 2004 and 2014. Outcome measures included changes in motor function and quality of life following AI, change in dose of other dopaminergic medications following AI, duration of infusion, adverse effects, reasons for cessation of AI and subsequent treatment after cessation. Mean duration of AI was 21.65 months. No patient achieved apomorphine monotherapy, and the mean reduction in the levodopa-equivalent dose of other dopaminergic medications after AI was 22.7%. The benefit of AI on motor function and quality of life was rated as 'much improved' or 'better' in 83% of patients. The most common reasons for discontinuation of AI were adverse effects and inadequate motor benefit. Most patients who discontinued AI were subsequently treated with another device-assisted therapy. AI is an effective therapy for severe motor response complications in PD, especially in the short and medium term. However, many patients cannot be maintained on AI in the longer term. © 2017 Royal Australasian College of Physicians.

Adverse drug event-related emergency department visits associated with complex chronic conditions.

Feinstein, James A; Feudtner, Chris; Kempe, Allison

2014-06-01

Outpatient adverse drug events (ADEs) can result in serious outcomes requiring emergency department (ED) visits and hospitalizations. The incidence and severity of ADEs in children with complex chronic conditions (CCCs), who often take multiple medications, is unknown. We sought to describe the characteristics of ADE-related ED visits, including association with CCC status; determine the implicated medications; and determine if CCC status increased the risk of ADE-related admission. Retrospective cohort study of ED visits by patients aged 0 to 18 years using a national sample. ADEs were identified by external cause of injury codes; cases with overdose, wrongful administration, self-harm, or diagnosis of malignancy were excluded. Multivariable logistic regression was used to test outcomes of having an ADE-related ED visit and of subsequent admission. All statistics accounted for the complex survey design. Of 144 million ED visits, 0.5% were associated with ADEs. Adjusting for age, gender, insurance type, day of week, and location of hospital, ADEs were associated with the presence of a CCC (odds ratio 4.76; 95% confidence interval: 4.45-5.10). The implicated medications differed significantly by CCC status. Adjusting for the same variables, ADEs were associated with subsequent inpatient admission (odds ratio 2.18; 95% confidence interval: 2.04-2.32) for all children; an interaction between ADE and CCC status was not significant. ED visits associated with ADEs were more likely to occur for children with CCCs, and the implicated drugs differed, but ADE-related admissions were not differentially affected by CCC status.

Changing social factors and their long-term implications for health.

PubMed

Wadsworthx, M E

1997-01-01

This paper presents findings and arguments to show the power of social factors to affect health at the individual and at the national level. Social factors most strongly and negatively associated with health, at both levels, are those that indicate disorganisation and disruption, perceived helplessness and lack of support, low educational attainment, and poverty. Adverse changes in these social factors and their negative effects on health have been observed in many studies. When such adverse changes affect the lives and health of children, and those who will become parents, they affect the present and long-term future health of individuals because of the processes of biological programming described in this and other papers presented here. Such adverse changes in social factors also adversely affect the social circumstances of childhood, which in turn have a negative impact on health. Because changing social factors affect biological programming and social capitalisation, awareness of the health damaging effects of recent social change provides information on the future health of the population.

Newly postulated neurodevelopmental risks of pediatric anesthesia: theories that could rock our world.

PubMed

Hays, Stephen Robert; Deshpande, Jayant K

2013-04-01

General anesthetics can induce apoptotic neurodegeneration and subsequent maladaptive behaviors in animals. Retrospective human studies suggest associations between early anesthetic exposure and subsequent adverse neurodevelopmental outcomes. The relevance of animal data to clinical practice is unclear and to our knowledge the causality underlying observed associations in humans is unknown. We reviewed newly postulated neurodevelopmental risks of pediatric anesthesia and discuss implications for the surgical care of children. We queried the MEDLINE®/PubMed® and EMBASE® databases for citations in English on pediatric anesthetic neurotoxicity with the focus on references from the last decade. Animal studies in rodents and primates demonstrate apoptotic neuropathology and subsequent maladaptive behaviors after exposure to all currently available general anesthetics with the possible exception of α2-adrenergic agonists. Similar adverse pathological and clinical effects occur after untreated pain. Anesthetic neurotoxicity in animals develops only after exposure above threshold doses and durations during a critical neurodevelopmental window of maximal synaptogenesis in the absence of concomitant painful stimuli. Anesthetic exposure outside this window or below threshold doses and durations shows no apparent neurotoxicity, while exposure in the context of concomitant painful stimuli is neuroprotective. Retrospective human studies suggest associations between early anesthetic exposure and subsequent adverse neurodevelopmental outcomes, particularly after multiple exposures. The causality underlying the associations is unknown. Ongoing investigations may clarify the risks associated with current practice. Surgical care of all patients mandates appropriate anesthesia. Neurotoxic doses and the duration of anesthetic exposure in animals may have little relevance to clinical practice, particularly surgical anesthesia for perioperative pain. The causality underlying the observed associations between early anesthetic exposure and subsequent adverse neurodevelopmental outcomes is unknown. Anesthetic exposure may be a marker of increased risk. Especially in young children, procedures requiring general anesthesia should be performed only as necessary and general anesthesia duration should be minimized. Alternatives to general anesthesia and the deferral of elective procedures beyond the first few years of life should be considered, as appropriate. Participation in ongoing efforts should be encouraged to generate further data. Copyright © 2013 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Interpregnancy interval following miscarriage and adverse pregnancy outcomes: systematic review and meta-analysis.

PubMed

Kangatharan, Chrishny; Labram, Saffi; Bhattacharya, Sohinee

2017-03-01

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 0.88, 1.02) were not affected by IPI. Similar findings were obtained in subgroup analyses when IPI of <6 months was compared with IPI of 6-12 months and >12 months. This is the first systematic review and meta-analysis providing clear evidence that an IPI of less than 6 months following miscarriage is not associated with adverse outcomes in the next pregnancy.

Is health impact assessment useful in the context of trade negotiations? A case study of the Trans Pacific Partnership Agreement.

Hirono, Katherine; Haigh, Fiona; Gleeson, Deborah; Harris, Patrick; Thow, Anne Marie; Friel, Sharon

2016-04-04

The Trans Pacific Partnership Agreement (TPP) is a recently concluded free trade agreement involving Australia and 11 other Pacific-rim nations, which has the potential for far-reaching impacts on public health. A health impact assessment (HIA) was carried out during the negotiations to determine the potential future public health impact in Australia and to provide recommendations to mitigate potential harms. This paper explores the findings and outcomes of the HIA, and how this approach can be used to provide evidence for public health advocacy. A modified version of the standard HIA process was followed. The HIA was led by technical experts in HIA, trade policy, and health policy, in collaboration with advocacy organisations concerned with the TPP and health. The HIA reviewed the provisions in leaked TPP text in order to determine their potential impact on future health policy. As part of this process, researchers developed policy scenarios in order to examine how TPP provisions may affect health policies and their subsequent impact to health for both the general and vulnerable populations. The four policy areas assessed were the cost of medicines, tobacco control, alcohol control and food labelling. In all areas assessed, the HIA found that proposed TPP provisions were likely to adversely affect health. These provisions are also likely to more adversely affect the health of vulnerable populations. The HIA produced relevant evidence that was useful in advocacy efforts by stakeholders, and engaging the public through various media platforms. Published by the BMJ Publishing Group Limited.

Breslau, Joshua; Lane, Michael; Sampson, Nancy; Kessler, Ronald C

2008-07-01

As part of a larger investigation of the adverse effects of mental disorders on role functioning, we examined the associations of early-onset mental disorders with subsequent educational attainment in a large nationally representative survey of the US adult population. Diagnoses and age of onset for each of 17 DSM-IV disorders were assessed through retrospective self-report with the fully structured WHO Composite International Diagnostic Instrument (CIDI). Survival analysis was used to examine the associations between early-onset DSM-IV/CIDI disorders and subsequent termination of schooling with controls for socio-demographic characteristics and childhood adversities (i.e. childhood traumatic events, childhood neglect, parental mental illness, family disruption, and low parental educational attainment). Mental disorders were found to be significantly associated with termination of schooling prior to completion of each of four educational milestones (primary school graduation, high school graduation, college entry, college graduation), with odds ratios in the range of 1.3-7.0. The proportion of school terminations attributable to mental disorders was largest for high school graduation (10.2%) but also meaningful for primary school graduation (3.8%), college entry (4.4%) and college graduation (2.6%). These results add to a growing body of evidence documenting a wide variety of adverse life course effects of mental disorders.

Approximately 1 in 20 unrelated donors are asked to make a second donation of hematopoietic progenitor cells, the majority for the same patient. Anthony Nolan undertook a study of subsequent hematopoietic progenitor cell donations made by its donors from 2005 to 2011, with the aims of predicting those donors more likely to be called for a second donation, assessing rates of serious adverse reactions and examining harvest yields. This was not a study of factors predictive of second allografts. During the study period 2591 donations were made, of which 120 (4.6%) were subsequent donations. The median time between donations was 179 days (range, 21–4016). Indications for a second allogeneic transplant included primary graft failure (11.7%), secondary graft failure (53.2%), relapse (30.6%) and others (1.8%). On multivariate analysis, bone marrow harvest at first donation was associated with subsequent donation requests (odds ratio 2.00, P=0.001). The rate of serious adverse reactions in donors making a subsequent donation appeared greater than the rate in those making a first donation (relative risk=3.29, P=0.005). Harvest yields per kilogram recipient body weight were equivalent between donations, although females appeared to have a lower yield at the subsequent donation. Knowledge of these factors will help unrelated donor registries to counsel their donors. PMID:23812935

An experimental investigation of a psychoeducational strategy designed to reduce men's endorsement of societal ideals of women's attractiveness.

PubMed

Yamamiya, Yuko; Thompson, J Kevin

2009-01-01

The current study evaluated whether a psychoeducational manipulation, focused on reducing an unrealistic view of women's attractiveness, might affect men's ratings of the attractiveness of females. The participants were 159 male undergraduate students who were randomly assigned to four conditions: psychoeducational message (beauty ideals; marketing strategies) and photo exposure (attractive females; household products). The results indicated that males pre-exposed to attractive female images subsequently evaluated average females as less attractive than those exposed to household products. However, a psychoeducational information condition designed to challenge "beauty ideals" did not reduce the adverse exposure effect and was comparable in effectiveness to the "marketing strategies" manipulation. The limitations of the findings are discussed and avenues for future research in this area offered.

It can cause symptoms due to visceral ischaemia, lower limb hypoperfusion, and distal embolisation. We present a case of a 61-year-old man with unresponsive hypertension, who was found to have an occluded right renal artery, and an extensive coral reef aorta with a marked pressure gradient across the lesion. Renal hypoperfusion secondary to aortic coral reef aorta was thought to be the cause for his hypertension. Endovascular placement of a balloon expandable uncovered stent resolved his hypertension within one month, with no adverse effects noted at subsequent follow-up. Endovascular treatment of coral reef aorta is technically possible and avoids a major vascular procedure. © The Author(s) 2014.

Proposed gravity-gradient dynamics experiments in lunar orbit using the RAE-B spacecraft

A series of seven gravity-gradient dynamics experiments is proposed utilizing the Radio Astronomy Explorer (RAE-B) spacecraft in lunar orbit. It is believed that none of the experiments will impair the spacecraft structure or adversely affect the continuation of the scientific mission of the satellite. The first experiment is designed to investigate the spacecraft dynamical behavior in the absence of libration damper action and inertia. It requires stable gravity-gradient capture of the spacecraft in lunar orbit with small amplitude attitude librations as a prerequisite. Four subsequent experiments involve partial retraction, ultimately followed by full redeployment, of one or two of the 230-meter booms forming the lunar-directed Vee-antenna. These boom length change operations will induce moderate amplitude angular librations of the spacecraft.

Impairment of Arterial Compliance in Cushing’s Syndrome

Maria Zedda, Angela; Mercuro, Giuseppe

2014-01-01

Abstract Arterial stiffness may be useful for stratifying cardiovascular risk in individuals suffering from a number of pathologies, such as hypertension, diabetes, obesity, dyslipidaemia and coronary artery disease. Cushing’s syndrome is underpinned by a complex metabolic syndrome, which is potentially implicated in the onset of blood vessel alterations and the increase in arterial wall stiffness. The aim of this paper was to perform a review about the most important studies conducted in order to evaluate the arterial distensibility profile of subjects affected by Cushing’s syndrome. Increased arterial stiffness may persist even after successful cure of this disease. It is therefore of fundamental importance to identify the presence of early vascular alterations in these patients, in order to commence their treatment and thus attempt to prevent the subsequent onset of adverse cardiovascular events.

A Cross-Cultural Longitudinal Examination of the Effect of Cumulative Adversity on the Mental and Physical Health of Older Adults

Self-oriented adversity refers to traumatic events that primarily inflict the self, whereas other-oriented adversity refers to events that affect the self by primarily targeting others. The present study aimed to examine whether cultural background moderates the effects of self-oriented and other-oriented adversity on mental and physical health of older adults. Using longitudinal data from the Israeli component of the Survey of Health and Retirement, we focused on 370 Jews and 239 Arabs who reported their exposure to various adversities across the lifespan, and completed questionnaires regarding mental and physical health. Results showed that the effect of self-oriented adversity on health did not differ among Jews and Arabs. However, other-oriented adversity showed a stronger effect on Arabs’ mental and physical health than on Jews’ health. Our findings suggest that the accumulation of adverse events that affect the self by primarily targeting others may have a stronger impact in collectivist cultures than in individualist cultures.

Earlier use of tobacco in adolescence is associated with numerous adverse outcomes later in life. Although a number of studies have linked individual differences in affective functioning to adolescent smoking, these have relied primarily on self-report measures, and the contribution of different dimensions of affect to the onset of tobacco use during this period remains unclear. The current study examined these issues in a sample of 180 adolescents recruited from an ongoing prospective, longitudinal study examining emotional development. At approximately age 12, participants completed a questionnaire measure of affective temperament and took part in a family interaction task that was coded observationally to provide measures of dysphoric, aggressive, and positive behaviors. At 2 subsequent assessments, which took place approximately 2.5 years and 4 years after the initial assessment, participants completed a questionnaire measure of substance use. In total, 70 participants initiated smoking between the ages of 12 and 17. An earlier onset of smoking was predicted by more aggressive and less positive observed behavior during the interaction task, as well as lower levels of self-reported temperamental Effortful Control. There were no associations between dysphoric behaviors, or temperamental measures of negative affectivity or surgency and the onset of smoking. The findings add to a small body of literature demonstrating that behavioral components of affect can prospectively predict substance use in adolescence and suggest that different dimensions of affect show unique relationships with early substance use.

2014-01-01

Adverse drug reactions (ADRs) to antiretroviral therapy (ART) are an important cause of hospitalization, treatment discontinuation, and regimen changes in both developed and developing countries. This study is the first to examine and understand ADRs in HIV-infected patients in Nicaragua. A retrospective descriptive study was conducted from May 2010 to March 2011, in a cohort of HIV-infected patients receiving ART at the largest public hospital in Managua, Nicaragua. Patients were identified based on ADRs reporting on a standardized antiretroviral pharmacotherapy form. Subsequently, chart reviews of these patients were performed in order to document the specific ADRs. Six hundred ninety-two patients on ART were included. The incidence of ADRs was 6.4% (95% confidence interval [CI] 4.5-8.2). Females demonstrated a higher incidence, that is, 10.2% (95% CI 5.3-15.1, P = .020). Patients treated with combinations of zidovudine (ZDV)/lamivudine (3TC) and emtricitabine (FTC)/tenofovir (TDF) had fewer ADRs (P < .01) than those using other combinations. Five patients were hospitalized or had a prolonged hospitalization secondary to ADRs, with no mortality attributed to ADR. The most common manifestations of ADRs were central nervous system (20 of 44), gastrointestinal (12 of 44), and dermatologic (8 of 44) reactions. Adverse drug reactions were classified as "likely ADRs" (25 of 44) and "possible ADRs" (19 of 44). No ADRs were preventable. Adverse drug reactions most frequently affected the central nervous system. No ADR was life threatening. The frequency of ADRs in this Nicaraguan patient population was less than that reported from other studies in resource-limited settings. © The Author(s) 2014.

Objective Vitamin D deficiency is a common problem in reproductive-aged women in the United States. The effect of vitamin D deficiency in pregnancy is unknown, but has been associated with adverse pregnancy outcomes. The objective of this study was to analyze the relationship between vitamin D deficiency in the first trimester and subsequent clinical outcomes. Study Design This is a retrospective cohort study. Plasma was collected in the first trimester from 310 nulliparous women with singleton gestations without significant medical problems. Competitive enzymatic vitamin D assays were performed on banked plasma specimens and pregnancy outcomes were collected after delivery. Logistic regression was performed on patients stratified by plasma vitamin D concentration and the following combined clinical outcomes: preeclampsia, preterm delivery, intrauterine growth restriction, gestational diabetes, and spontaneous abortion. Results Vitamin D concentrations were obtained from 235 patients (mean age 24.3 years, range 18-40 years). Seventy percent of our study population was vitamin D insufficient with a serum concentration less than 30 ng/mL (mean serum concentration 27.6 ng/mL, range 13-71.6 ng/mL). Logistic regression was performed adjusting for age, race, body mass index, tobacco use, and time of year. Adverse pregnancy outcomes included preeclampsia, growth restriction, preterm delivery, gestational diabetes, and spontaneous abortion. There was no association between vitamin D deficiency and composite adverse pregnancy outcomes with an adjusted odds ratio of 1.01 (p value 0.738, 95% confidence intervals 0.961-1.057). Conclusion Vitamin D deficiency did not associate with adverse pregnancy outcomes in this study population. However, the high percentage of affected individuals highlights the prevalence of vitamin D deficiency in young, reproductive-aged women. PMID:25898021

Sound evidence has linked the experience of adversity with depression. Less is known about this association over time. The aim of this study is to determine whether or not social adversity experienced by pregnant women is associated with their patterns of depressive symptoms over their reproductive life course. Data were obtained from a cohort of women collected at their first obstetrical clinic visit of an index pregnancy (time-point 1) and at a further six time-points to 27 years following the birth. Latent Class Growth Modelling was used to estimate trajectories of women's depressive symptoms over this time period. Logistic regression modelling determined the prospective association between measures of adversity in pregnancy and 27-year postpartum depression trajectories, controlling for potential confounders. Experiencing financial problems, housing problems, serious disagreements with partners and with others, and experiencing serious health problems in pregnancy were associated with membership of high and middle depression trajectories over the 27 years. Having someone close die or have a serious illness was associated with the high depression trajectory only. Younger maternal age and low family-income at first clinic visit were also associated with an increased risk of women's membership of both high and middle depression trajectories. Experiencing adversity during pregnancy predicts subsequent patterns of maternal depression over an extended period of women's reproductive life course. It is not clear whether women's experiences of adversity during pregnancy were causally associated with subsequent depression or whether there are other explanations of the observed association.

A prospective study of marine phytoplankton and reported ...

EPA Pesticide Factsheets

BACKGROUND: Blooms of marine phytoplankton may adversely affect human health. The potential public health impact of low-level exposures is not well established, and few prospective cohort studies of recreational exposures to marine phytoplankton have been conducted.OBJECTIVE: We evaluated the association between phytoplankton cell counts and subsequent illness among recreational beachgoers.METHODS:We recruited beachgoers at Boquer6n Beach, Puerto Rico, during the summer of 2009. We conducted interviews at three time points to assess baseline health, water activities, and subsequent illness. Daily water samples were quantitatively assayed for phytoplankton cell count. Logistic regression models, adjusted for age and sex, were used to assess the association between exposure to three categories of phytoplankton concentration and subsequent illness.RESULTS: During 26 study days, 15,726 individuals successfully completed all three interviews. Daily total phytoplankton cell counts ranged from 346 to 2,012 cells/ml (median, 712 cells/ml). The category with the highest (≥75th percentile) total phytoplankton cell count was associated with eye irritation [adjusted odds ratio (OR) = 1.30; 95% confidence interval (Cl): 1.01, 1.66], rash (OR = 1.27; 95% Cl: 1.02, 1.57), and earache (OR = 1.25; 95% Cl: 0.88, 1.77). In phytoplankton group-specific analyses, the category with the highest Cyanobacteria counts was associated with respiratory illness (OR = 1.37; 95% Cl: 1.12, 1

Childhood adversity is a risk factor for the development of depression and can also affect clinical course. We investigated this specifically in treatment-resistant depression (TRD). One hundred and thirty-seven patients with TRD previously admitted to an inpatient affective disorders unit were included. Clinical, demographic and childhood adversity (physical, sexual, emotional abuse; bullying victimization, traumatic events) data were obtained during admission. Associations between childhood adversity, depressive symptoms and clinical course were investigated. Most patients had experienced childhood adversity (62%), with traumatic events (35%) and bullying victimization (29%) most commonly reported. Childhood adversity was associated with poorer clinical course, including earlier age of onset, episode persistence and recurrence. Logistic regression analyses revealed childhood adversity predicted lifetime suicide attempts (OR 2.79; 95% CI 1.14, 6.84) and childhood physical abuse predicted lifetime psychosis (OR 3.42; 95% CI 1.00, 11.70). The cross-sectional design and retrospective measurement of childhood adversity are limitations of the study. Childhood adversity was common amongst these TRD patients and was associated with poor clinical course, psychosis and suicide attempts. Routine assessment of early adversity may help identify at risk individuals and inform clinical intervention. Copyright © 2013 Elsevier B.V. All rights reserved.

Non-communicable diseases (NCDs) are a major cause of premature mortality. Recent studies show that predispositions for NCDs may arise from early-life exposure to low concentrations of environmental contaminants. This developmental origins of health and disease (DOHaD) paradigm suggests that programming of an embryo can be disrupted, changing the homeostatic set point of biological functions. Epigenetic alterations are a possible underlying mechanism. Here, we investigated the DOHaD paradigm by exposing zebrafish to subtoxic concentrations of the ubiquitous contaminant cadmium during embryogenesis, followed by growth under normal conditions. Prolonged behavioral responses to physical stress and altered antioxidative physiology were observed approximately ten weeks after termination of embryonal exposure, at concentrations that were 50–3200-fold below the direct embryotoxic concentration, and interpreted as altered developmental programming. Literature was explored for possible mechanistic pathways that link embryonic subtoxic cadmium to the observed apical phenotypes, more specifically, the probability of molecular mechanisms induced by cadmium exposure leading to altered DNA methylation and subsequently to the observed apical phenotypes. This was done using the adverse outcome pathway model framework, and assessing key event relationship plausibility by tailored Bradford-Hill analysis. Thus, cadmium interaction with thiols appeared to be the major contributor to late-life effects. Cadmium-thiol interactions may lead to depletion of the methyl donor S-adenosyl-methionine, resulting in methylome alterations, and may, additionally, result in oxidative stress, which may lead to DNA oxidation, and subsequently altered DNA methyltransferase activity. In this way, DNA methylation may be affected at a critical developmental stage, causing the observed apical phenotypes. PMID:27827847

Xenon/remifentanil anesthesia protects against adverse effects of losartan on hemodynamic challenges induced by anesthesia and acute blood loss.

The authors aimed to test the hypothesis that xenon anesthesia limits adverse hypotensive effects of losartan during acute hemorrhage. In six conscious unsedated Beagle dogs, the systemic and pulmonary circulation were monitored invasively, and two subsequent 60-min hypotensive challenges were performed by (a) induction (propofol) and maintenance of anesthesia with isoflurane/remifentanil or xenon/remifentanil and by (b) subsequent hemorrhage (20 mL kg⁻¹ within 5 min) from a central vein. The same amount of blood was retransfused 1 h after hemorrhage. Experiments were performed with or without acute angiotensin II receptor subtype 1 blockade by i.v. losartan (100 μg·kg⁻¹·min⁻¹) starting 45 min before induction of anesthesia. Four experiments were performed in each individual dog. Xenon/remifentanil anesthesia provided higher baseline mean arterial blood pressure (85 ± 6 mmHg) than isoflurane/remifentanil anesthesia (67 ± 3 mmHg). In losartan-treated animals, isoflurane/remifentanil caused significant hypotension (42 ± 4 mmHg for isoflurane/remifentanil vs. 71 ± 6 mmHg for xenon/remifentanil). Independent of losartan, hemorrhage did not induce any further reduction of mean arterial blood pressure or cardiac output in either group. Spontaneous hemodynamic recovery was observed in all groups before retransfusion was started. Losartan did not alter the adrenaline, noradrenaline, and vasopressin response to acute hemorrhage. Losartan potentiates hypotension induced by isoflurane/remifentanil anesthesia but does not affect the hemodynamic stability during xenon/remifentanil anesthesia. Losartan does not deteriorate the hemodynamic adaptation to hemorrhage of 20 mL kg⁻¹ during xenon/remifentanil and isoflurane/remifentanil anesthesia. Therefore, xenon/remifentanil anesthesia protects against circulatory side effects of losartan pretreatment and thus may afford safer therapeutic use of losartan during acute hemorrhage.

Exposure to light at night (LAN) has increased dramatically in recent decades. Animal studies have shown that chronic dim LAN induced obesity and glucose intolerance. Furthermore, several studies in humans have demonstrated that chronic exposure to artificial LAN may have adverse health effects with an increased risk of metabolic disorders, including type 2 diabetes. It is well-known that acute exposure to LAN affects biological clock function, hormone secretion and the activity of the autonomic nervous system, but data on the effects of LAN on glucose homeostasis are lacking. This study aimed to investigate the acute effects of LAN on glucose metabolism. Male Wistar rats were subjected to i.v. glucose or insulin tolerance tests while exposed to 2 h of LAN in the early or late dark phase. In subsequent experiments, different light intensities and wavelengths were used. LAN exposure early in the dark phase at ZT15 caused increased glucose responses during the first 20 min after glucose infusion (p < 0.001), whereas LAN exposure at the end of the dark phase, at ZT21, caused increased insulin responses during the first 10 min (p < 0.01), indicating that LAN immediately induces glucose intolerance in rats. Subsequent experiments demonstrated that the effect of LAN was both intensity- and wavelength-dependent. White light of 50 and 150 lx induced greater glucose responses than 5 and 20 lx, whereas all intensities other than 5 lx reduced locomotor activity. Green light induced glucose intolerance, but red and blue light did not, suggesting the involvement of a specific retina-brain pathway. Together, these data show that exposure to LAN has acute adverse effects on glucose metabolism in a time-, intensity- and wavelength-dependent manner.

Racial and/or ethnic minorities carry the highest burden of many adverse health outcomes intergenerationally We propose a paradigm in which developmental programming exacerbates the effects of racial patterning of adverse environmental conditions, thereby contributing to health disparity persistence. Evidence that developmental programming induces a heightened response to adverse exposures ("second hits") encountered later in life is considered. We evaluated the evidence for the second hit phenomenon reported in animal and human studies from three domains (air, stress, nutrition). Original research including a gestational exposure and a childhood or adulthood second hit exposure was reviewed. Evidence from animal studies suggest that prenatal exposure to air pollutants is associated with an exaggerated reaction to postnatal air pollution exposure, which results in worse health outcomes. It also indicates offspring exposed to prenatal maternal stress produce an exaggerated response to subsequent stressors, including anxiety and hyper-responsiveness of the hypothalamic-pituitary-adrenal axis. Similarly, prenatal and postnatal Western-style diets induce synergistic effects on weight gain, metabolic dysfunction, and atherosclerotic risk. Cross-domain second hits (e.g., gestational air pollution followed by childhood stressor) were also considered. Suboptimal gestational environments induce exaggerated offspring responses to subsequent environmental and social exposures. These developmental programming effects may result in enhanced sensitivity of ongoing, racially patterned, adverse exposures in race/ethnic minorities, thereby exacerbating health disparities from one generation to the next. Empirical assessment of the hypothesized role of priming processes in the propagation of health disparities is needed. Future social epidemiology research must explicitly consider synergistic relationships among social environmental conditions to which gestating females are exposed and offspring exposures when assessing causes for persistent health disparities.

Lactic Acidosis with Chloramphenicol Treatment in a Child with Cystic Fibrosis.

Children with cystic fibrosis are commonly colonized with multi-resistant bacteria. In such patients, infectious exacerbation may require salvage therapy with uncommonly used antimicrobials, including chloramphenicol. Chloramphenicol is rarely used nowadays because of the associated severe adverse events. We describe the case of a 15-year-old female with terminal cystic fibrosis who required intravenous (IV) chloramphenicol treatment for a Burkholderia cepacia (B. cepacia) exacerbation. The child subsequently developed lactic acidosis and secondary respiratory compensation adding to her baseline respiratory distress. Based on the Naranjo scale, the probability of chloramphenicol being the cause of the hyperlactatemia and associated respiratory distress was rated as probable, as the adverse effects resolved upon discontinuation of the drug. Subsequent genotyping for mitochondrial polymorphism (G3010A) confirmed a possible susceptibility to lactic acidosis from mitochondrial RNA-inhibiting agents such as chloramphenicol. Hyperlactatemia is a rare but life threatening adverse effect that has been previously reported with chloramphenicol exposure, but is not generally thought of. Clinicians should be aware of this potentially life threatening, but reversible adverse event. Lactate should be monitored under chloramphenicol and it should be discontinued as soon as this complication is suspected, especially in patients with low respiratory reserve. © 2017 Journal of Population Therapeutics and Clinical Pharmacology.

Maternal exposure to di(2-ethylhexyl)phthalate (DEHP) promotes the transgenerational inheritance of adult-onset reproductive dysfunctions through the female germline in mice

DOE Office of Scientific and Technical Information (OSTI.GOV)

Pocar, Paola, E-mail: paola.pocar@unimi.it; Fianda

Endocrine disruptors (EDs) are compounds known to promote transgenerational inheritance of adult-onset disease in subsequent generations after maternal exposure during fetal gonadal development. This study was designed to establish whether gestational and lactational exposure to the plasticizer di(2-ethylhexyl)phthalate (DEHP) at environmental doses promotes transgenerational effects on reproductive health in female offspring, as adults, over three generations in the mouse. Gestating F0 mouse dams were exposed to 0, 0.05, 5 mg/kg/day DEHP in the diet from gestational day 0.5 until the end of lactation. The incidence of adult-onset disease in reproductive function was recorded in F1, F2 and F3 female offspring.more » In adult F1 females, DEHP exposure induced reproductive adverse effects with: i) altered ovarian follicular dynamics with reduced primordial follicular reserve and a larger growing pre-antral follicle population, suggesting accelerated follicular recruitment; ii) reduced oocyte quality and embryonic developmental competence; iii) dysregulation of the expression profile of a panel of selected ovarian and pre-implantation embryonic genes. F2 and F3 female offspring displayed the same altered reproductive morphological phenotype and gene expression profiles as F1, thus showing transgenerational transmission of reproductive adverse effects along the female lineage. These findings indicate that in mice exposure to DEHP at doses relevant to human exposure during gonadal sex determination significantly perturbs the reproductive indices of female adult offspring and subsequent generations. Evidence of transgenerational transmission has important implications for the reproductive health and fertility of animals and humans, significantly increasing the potential biohazards of this toxicant. - Highlights: • Maternal exposure to DEHP transgenerationally affects female reproductive health. • DEHP reduced ovarian follicular reserve up to the third generation. • DEHP reduced oocyte and blastocyst developmental competence up to F3. • DEHP altered expression levels for key genes in ovary and blastocysts up to F4. • DEHP's adverse effects were observed at doses relevant for human exposure.« less

A cross-cultural longitudinal examination of the effect of cumulative adversity on the mental and physical health of older adults.

PubMed

Palgi, Yuval; Shrira, Amit

2016-03-01

Self-oriented adversity refers to traumatic events that primarily inflict the self, whereas other-oriented adversity refers to events that affect the self by primarily targeting others. The present study aimed to examine whether cultural background moderates the effects of self-oriented and other-oriented adversity on mental and physical health of older adults. Using longitudinal data from the Israeli component of the Survey of Health and Retirement, we focused on 370 Jews and 239 Arabs who reported their exposure to various adversities across the life span, and completed questionnaires regarding mental and physical health. Results showed that the effect of self-oriented adversity on health did not differ among Jews and Arabs. However, other-oriented adversity showed a stronger effect on Arabs' mental and physical health than on Jews' health. Our findings suggest that the accumulation of adverse events that affect the self by primarily targeting others may have a stronger impact in collectivist cultures than in individualist cultures.

Witnessing domestic violence during childhood is associated with psychopathic traits in adult male criminal offenders.

Dargis, Monika; Koenigs, Michael

2017-04-01

While there is growing evidence that suffering physical abuse during childhood is subsequently associated with psychopathic traits in both juvenile and adult offenders, there is considerably less research on whether exposure to domestic violence as a witness, rather than as a direct victim, influences the subsequent presentation of psychopathic traits in adulthood. Accordingly, the current study examined the relationship between witnessing domestic violence during childhood (i.e., witnessing, hearing, or intervening in abuse against a parent/sibling) and psychopathic traits in adulthood in a sample of n = 127 incarcerated male offenders. As predicted, witnessing domestic violence was significantly associated with overall level of psychopathy, with a particularly strong relationship to the interpersonal/affective features of psychopathy. Importantly, this relationship held when controlling for the experience of domestic violence as a direct victim. These results add to the growing body of literature linking adverse and traumatic events during childhood with psychopathic traits later in life, and suggest that domestic violence exposure may be one factor contributing to the manipulative, interpersonal style exhibited by individuals high in psychopathy.

Space Launch System Scale Model Acoustic Test Ignition Overpressure Testing

NASA Technical Reports Server (NTRS)

Nance, Donald K.; Liever, Peter A.

2015-01-01

The overpressure phenomenon is a transient fluid dynamic event occurring during rocket propulsion system ignition. This phenomenon results from fluid compression of the accelerating plume gas, subsequent rarefaction, and subsequent propagation from the exhaust trench and duct holes. The high-amplitude unsteady fluid-dynamic perturbations can adversely affect the vehicle and surrounding structure. Commonly known as ignition overpressure (IOP), this is an important design-to environment for the Space Launch System (SLS) that NASA is currently developing. Subscale testing is useful in validating and verifying the IOP environment. This was one of the objectives of the Scale Model Acoustic Test (SMAT), conducted at Marshall Space Flight Center (MSFC). The test data quantifies the effectiveness of the SLS IOP suppression system and improves the analytical models used to predict the SLS IOP environments. The reduction and analysis of the data gathered during the SMAT IOP test series requires identification and characterization of multiple dynamic events and scaling of the event waveforms to provide the most accurate comparisons to determine the effectiveness of the IOP suppression systems. The identification and characterization of the overpressure events, the waveform scaling, the computation of the IOP suppression system knockdown factors, and preliminary comparisons to the analytical models are discussed.

2016-03-01

This study addresses how job seekers' experiences of rude and discourteous treatment--incivility--can adversely affect self-regulatory processes underlying job searching. Using the social-cognitive model (Zimmerman, 2000), we integrate social-cognitive theory with the goal orientation literature to examine how job search self-efficacy mediates the relationship between incivility and job search behaviors and how individual differences in learning goal orientation and avoid-performance goal orientation moderate that process. We conducted 3 studies with diverse methods and samples. Study 1 employed a mixed-method design to understand the nature of incivility within the job search context and highlight the role of attributions in linking incivility to subsequent job search motivation and behavior. We tested our hypotheses in Study 2 and 3 employing time-lagged research designs with unemployed job seekers and new labor market entrants. Across both Study 2 and 3 we found evidence that the negative effect of incivility on job search self-efficacy and subsequent job search behaviors are stronger for individuals low, rather than high, in avoid-performance goal orientation. Theoretical implications of our findings and practical recommendations for how to address the influence of incivility on job seeking are discussed. (c) 2016 APA, all rights reserved).

Objective Recent research demonstrating concurrent associations between mental disorders and peptic ulcers has renewed interest in links between psychological factors and ulcers. However, little is known about associations between temporally prior mental disorders and subsequent ulcer onset. Nor has the potentially confounding role of childhood adversities been explored. The objective of this study was to examine associations between a wide range of temporally prior DSM-IV mental disorders and subsequent onset of ulcer, without and with adjustment for mental disorder comorbidity and childhood adversities. Methods Face-to-face household surveys conducted in 19 countries (n=52,095; person years=2,096,486).The Composite International Diagnostic Interview retrospectively assessed lifetime prevalence and age at onset of 16 DSM-IV mental disorders. Peptic ulcer onset was assessed in the same interview by self-report of physician’s diagnosis and year of diagnosis. Survival analyses estimated associations between first onset of mental disorders and subsequent ulcer onset. Results After comorbidity and sociodemographic adjustment, depression, social phobia, specific phobia, post-traumatic stress disorder, intermittent explosive disorder, alcohol and drug abuse disorders were significantly associated with ulcer onset (ORs 1.3-1.6). Increasing number of lifetime mental disorders was associated with ulcer onset in a dose-response fashion. These associations were only slightly attenuated by adjustment for childhood adversities. Conclusions A wide range of mental disorders were linked with the self-report of subsequent peptic ulcer onset. These associations require confirmation in prospective designs, but are suggestive of a role for mental disorders in contributing to ulcer vulnerability, possibly through abnormalities in the physiological stress response associated with mental disorders.

Adverse prenatal environments can promote metabolic disease in offspring and subsequent generations. Animal models and epidemiological data implicate epigenetic inheritance but mechanisms remain unknown. In an intergenerational developmental programming model affecting F2 metabolism, we demonstrate that the in utero nutritional environment of F1 embryos alters the germline DNA methylome of F1 adult males in a locus-specific manner. Differentially methylated regions are hypomethylated and enriched in nucleosome-retaining regions. A substantial fraction is resistant to early embryo methylation reprogramming, potentially impacting F2 development. Importantly, differential methylation is not maintained in F2 tissues, yet locus-specific expression is perturbed. Thus, in utero nutritional exposures during critical windows of germ cell development can impact the male germline methylome, associated with metabolic disease in offspring. PMID:25011554

Self-expanding metal stents (SEMS) are the treatment of choice for advanced esophageal cancers. Literature is scarce on risk factors predictors for adverse events after SEMS placement. Assess risk factors for adverse events after SEMS placement in advanced esophageal cancer and evaluate survival after SEMS placement. Cross-sectional study of patients with advanced esophageal cancer referred for SEMS placement, during a period of 3 years. Ninety-seven patients with advanced esophageal cancer placed SEMS. Adverse events were more common when tumors were located at the level of the distal esophagus/cardia (47% vs 23%, P = 0.011, OR 3.1), with statistical significance being kept in the multivariate analysis (OR 3.1, P = 0.018). Time until adverse events was lower in the tumors located at the level of the distal esophagus/cardia (P = 0.036). Survival was higher in patients who placed SEMS with curative intent (327 days [126-528] vs. 119 days [91-147], P = 0.002) and in patients submitted subsequently to surgery compared with those who did just chemo/radiotherapy or who did not do further treatment (563 days [378-748] vs. 154 days [133-175] vs. 46 days [20-72], P < 0.001). Subsequent treatment kept statistical significance in the multivariate analysis (HR 3.4, P < 0.001). SEMS allow palliation of dysphagia in advanced esophageal cancer and are associated with an increased out-of-hospital survival, as long as there are conditions for further treatments. Tumors located at the level of the distal esophagus/cardia are associated with a greater number of adverse events, which also occur earlier. © 2016 International Society for Diseases of the Esophagus.

Adverse weather impacts on arable cropping systems

NASA Astrophysics Data System (ADS)

Gobin, Anne

2016-04-01

Damages due to extreme or adverse weather strongly depend on crop type, crop stage, soil conditions and management. The impact is largest during the sensitive periods of the farming calendar, and requires a modelling approach to capture the interactions between the crop, its environment and the occurrence of the meteorological event. The hypothesis is that extreme and adverse weather events can be quantified and subsequently incorporated in current crop models. Since crop development is driven by thermal time and photoperiod, a regional crop model was used to examine the likely frequency, magnitude and impacts of frost, drought, heat stress and waterlogging in relation to the cropping season and crop sensitive stages. Risk profiles and associated return levels were obtained by fitting generalized extreme value distributions to block maxima for air humidity, water balance and temperature variables. The risk profiles were subsequently confronted with yields and yield losses for the major arable crops in Belgium, notably winter wheat, winter barley, winter oilseed rape, sugar beet, potato and maize at the field (farm records) to regional scale (statistics). The average daily vapour pressure deficit (VPD) and reference evapotranspiration (ET0) during the growing season is significantly lower (p < 0.001) and has a higher variability before 1988 than after 1988. Distribution patterns of VPD and ET0 have relevant impacts on crop yields. The response to rising temperatures depends on the crop's capability to condition its microenvironment. Crops short of water close their stomata, lose their evaporative cooling potential and ultimately become susceptible to heat stress. Effects of heat stress therefore have to be combined with moisture availability such as the precipitation deficit or the soil water balance. Risks of combined heat and moisture deficit stress appear during the summer. These risks are subsequently related to crop damage. The methodology of defining meteorological risks and subsequently relating the risk to the cropping calendar will be demonstrated for major arable crops in Belgium. Physically based crop models assist in understanding the links between adverse weather events, sensitive crop stages and crop damage.

To document the impact on clinical practice in England of media attention around possible adverse effects of paroxetine. Analysis of national selective serotonin reuptake inhibitor (SSRI) prescribing trends and yellow-card adverse drug reaction reports, 2001-2004. From a steady state in 2001, paroxetine prescribing declined sharply from April 2002, coinciding with a USA regulatory action; the subsequent decline in paroxetine prescribing was 1.87% per month (95% confidence interval - 2.06, -1.68). Other SSRI prescribing increased by 1% per month until a major UK review of SSRIs in children in December 2003, after which prescribing plateaued. Media publicity was associated with short-term peaks in yellow-card reports related to paroxetine. Falls in paroxetine and other SSRI prescribing in the UK coincided, respectively, with regulatory communications from the USA and the UK, but associations may have noncausal or other explanations. Reports of adverse reactions to paroxetine appeared to increase after adverse media publicity about the drug.

Parenting begets parenting: A neurobiological perspective on early adversity and the transmission of parenting styles across generations.

PubMed

Lomanowska, A M; Boivin, M; Hertzman, C; Fleming, A S

2017-02-07

The developing brains of young children are highly sensitive to input from their social environment. Nurturing social experience during this time promotes the acquisition of social and cognitive skills and emotional competencies. However, many young children are confronted with obstacles to healthy development, including poverty, inappropriate care, and violence, and their enhanced sensitivity to the social environment means that they are highly susceptible to these adverse childhood experiences. One source of social adversity in early life can stem from parenting that is harsh, inconsistent, non-sensitive or hostile. Parenting is considered to be the cornerstone of early socio-emotional development and an adverse parenting style is associated with adjustment problems and a higher risk of developing mood and behavioral disorders. Importantly, there is a growing literature showing that an important predictor of parenting behavior is how parents, especially mothers, were parented themselves. In this review, we examine how adversity in early-life affects mothering behavior in later-life and how these effects may be perpetuated inter-generationally. Relying on studies in humans and animal models, we consider evidence for the intergenerational transmission of mothering styles. We then describe the psychological underpinnings of mothering, including responsiveness to young, executive function and affect, as well as the physiological mediators of mothering behavior, including hormones, brain regions and neurotransmitters, and we consider how development in these relevant domains may be affected by adversity experienced in early life. Finally, we explore how genes and early experience interact to predict mothering behavior, including the involvement of epigenetic mechanisms. Understanding how adverse parenting begets adverse parenting in the next generation is critical for designing interventions aimed at preventing this intergenerational cycle of early adversity.

Adverse childhood experience and asthma onset: a systematic review.

PubMed

Exley, Daniel; Norman, Alyson; Hyland, Michael

2015-06-01

Adverse childhood experiences such as abuse and neglect are associated with subsequent immune dysregulation. Some studies show an association between adverse childhood experiences and asthma onset, although significant disparity in results exists in the published literature. We aimed to review available studies employing a prospective design that investigates associations between adverse childhood experience and asthma. A search protocol was developed and studies were drawn from four electronic journal databases. Studies were selected in accordance with pre-set inclusion criteria and relevant data were extracted. 12 studies, assessing data from a total of 31 524 individuals, were identified that investigate the impact of a range of adverse childhood experiences on the likelihood of developing asthma. Evidence suggests that chronic stress exposure and maternal distress in pregnancy operate synergistically with known triggers such as traffic-related air pollution to increase asthma risk. Chronic stress in early life is associated with an increased risk of asthma onset. There is evidence that adverse childhood experience increases the impact of traffic-related air pollution and inconsistent evidence that adverse childhood experience has an independent effect on asthma onset.

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.

The alarming reality of medication error: a patient case and review of Pennsylvania and National data.

A 71-year-old female accidentally received thiothixene (Navane), an antipsychotic, instead of her anti-hypertensive medication amlodipine (Norvasc) for 3 months. She sustained physical and psychological harm including ambulatory dysfunction, tremors, mood swings, and personality changes. Despite the many opportunities for intervention, multiple health care providers overlooked her symptoms. Errors occurred at multiple care levels, including prescribing, initial pharmacy dispensation, hospitalization, and subsequent outpatient follow-up. This exemplifies the Swiss Cheese Model of how errors can occur within a system. Adverse drug events (ADEs) account for more than 3.5 million physician office visits and 1 million emergency department visits each year. It is believed that preventable medication errors impact more than 7 million patients and cost almost $21 billion annually across all care settings. About 30% of hospitalized patients have at least one discrepancy on discharge medication reconciliation. Medication errors and ADEs are an underreported burden that adversely affects patients, providers, and the economy. Medication reconciliation including an 'indication review' for each prescription is an important aspect of patient safety. The decreasing frequency of pill bottle reviews, suboptimal patient education, and poor communication between healthcare providers are factors that threaten patient safety. Medication error and ADEs cost billions of health care dollars and are detrimental to the provider-patient relationship.

Arthritis resulting from recurrent intra-articular bleeding in individuals with hemophilia can be severely debilitating due to joint pain and stiffness with subsequent loss of mobility and function. Very limited studies have investigated the potential benefits of joint mobilization for this condition. This case series is a preliminary investigation of safety, as well as immediate and short-term clinical benefits, associated with gentle knee and ankle joint mobilization in people with hemophilic arthropathy. A single intervention of joint mobilization was applied to the affected knees and/or ankles of 16 individuals with severe or moderate hemophilia within a public hospital setting. Adverse events, as well as immediate (pain-free passive joint range, Timed Up and Go Test with maximum pain numerical rating scale) and short-term (Lower Extremity Functional Scale) effects of the intervention were evaluated with a repeated measures ANOVA. There were no adverse events. An immediate significant increase was observed in pain-free passive ankle joint range of motion ( p  < 0.05) following the joint mobilization intervention. The findings of this case series suggest that gentle joint mobilization techniques may be safely considered as part of a multimodal management approach for hemophilic arthropathy.

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

Responding to information about children in adversity: ten years of a differential response model in Western Australia.

PubMed

Harries, Maria; Cant, Rosemary L; Bilson, Andy; Thorpe, David

2015-01-01

This article uses a comprehensive database about children in adversity collected over the 16-year period from 1990 to 2005 in the state of Western Australia. The focus of this interrogation is the effect of major changes in responses to information about children brought to the attention of the Western Australian statutory authority in a 10-year period during this 16 years. The initiative for these changes was termed New Directions, and its associated policy and practice changes were aimed at differentiating information expressing concerns about children and families from allegations of child maltreatment. They emphasized the provision of supportive and empowering services to families experiencing difficulties - a form of differential response to children in adversity. The article covers the period leading up to the policy and practice change and the 10 years during which these changes were implemented. It examines some effects of the new policy and comments on whether the changes resulted in missed opportunities to protect children from harm, which in turn, might have led to higher rates of re-reporting. The authors present an overall picture of the nature of the information accepted by the statutory authority and how the interpretation of that information might have affected subsequent outcomes for children. In doing so, it shows that the policy and consequential practice changes associated with a differential response mechanism had long lasting positive effects that, despite dire warnings, did not compromise the protection of the small group of children identified as requiring protective interventions.

Traditionally, adversity was defined as the accumulation of environmental events (allostatic load). Recently however, a mismatch between the early and the later (adult) environment (mismatch) has been hypothesized to be critical for disease development, a hypothesis that has not yet been tested explicitly in humans. We explored the impact of timing of life adversity (childhood and past year) on anxiety and depression levels (N = 833) and brain morphology (N = 129). Both remote (childhood) and proximal (recent) adversities were differentially mirrored in morphometric changes in areas critically involved in emotional processing (i.e. amygdala/hippocampus, dorsal anterior cingulate cortex, respectively). The effect of adversity on affect acted in an additive way with no evidence for interactions (mismatch). Structural equation modeling demonstrated a direct effect of adversity on morphometric estimates and anxiety/depression without evidence of brain morphology functioning as a mediator. Our results highlight that adversity manifests as pronounced changes in brain morphometric and affective temperament even though these seem to represent distinct mechanistic pathways. A major goal of future studies should be to define critical time periods for the impact of adversity and strategies for intervening to prevent or reverse the effects of adverse childhood life experiences. © The Author (2015).

To investigate whether first trimester maternal serum sex hormone-binding globulin (SHBG) concentrations are altered in women who subsequently develop preeclampsia or other pregnancy complications. Women undergoing first trimester combined ultrasound and biochemical screening for chromosomal anomalies. We searched the database and identified 32 pregnancies resulting in miscarriage, 64 pregnancies with preexisting or gestational diabetes mellitus, 107 with fetal growth restriction, 103 with preeclampsia, 64 with pregnancy-induced hypertension, and 26 with spontaneous preterm delivery. We also selected 400 controls from among the population of pregnancies that had a delivery of a normal baby with no pregnancy complications. Maternal serum SHBG concentrations were measured retrospectively using a competitive chemiluminescent immunoassay. The levels between those with normal outcome and those resulting in adverse outcome were compared. The median maternal serum SHBG concentration was not significantly different from controls, in those that subsequently developed preeclampsia (median MoM 1.05), non-proteinuric hypertension (median MoM 0.94) or preterm delivery (median MoM 1.15). The levels were significantly lower in those with diabetes (median MoM, 0.81 p=0.0005) and those pregnancies resulting in miscarriage (median MoM 0.80, p=0.008). First trimester maternal serum SHBG concentrations are no different from controls in women who subsequently develop preeclampsia, pregnancy-induced hypertension, fetal growth restriction, or preterm delivery. Levels are reduced in those who subsequently miscarry or in those presenting with diabetes.

Does heparin ablate the advantageous effects of cyclic adenosine mono-phosphate (cAMP) modulators during pre-in vitro maturation (IVM) and have a deleterious effect in standard oocyte IVM? Heparin interrupts energy metabolism and meiotic progression and adversely affects subsequent development of oocytes under conditions of elevated cAMP levels in cumulus-oocyte complexes (COCs) after pre-IVM treatment with forskolin. In animal IVM studies, artificial regulation of meiotic resumption by cAMP-elevating agents improves subsequent oocyte developmental competence. Heparin has no effect on spontaneous, FSH- or epidermal growth factor (EGF)-stimulated meiotic maturation. An in vitro cross-sectional study was conducted using immature mouse and human COCs. Depending on individual experimental design, COCs were treated during pre-IVM with or without heparin, in the presence or absence of forskolin and/or 3-isobutyl-1-methylxanthine (IBMX), and then COC function was assessed by various means. Forty-two women with polycystic ovaries (PCOs) or polycystic ovarian syndrome (PCOS) donated COCs after oocyte retrieval in a non-hCG-triggered IVM cycle. COCs were collected in pre-IVM treatments and then cultured for 40 h and meiotic progression was assessed. COCs from 21- to 24-day-old female CBA F1 mice were collected 46 h after stimulation with equine chorionic gonadotrophin. Following treatments, COCs were checked for meiotic progression. Effects on mouse oocyte metabolism were measured by assessing oocyte mitochondrial membrane potential using JC-1 staining and oocyte ATP content. Post-IVM mouse oocyte developmental competence was assessed by in vitro fertilization and embryo production. Blastocyst quality was evaluated by differential staining of inner cell mass (ICM) and trophectoderm (TE) layers. In the absence of heparin in pre-IVM culture, the addition of cAMP modulators did not affect human oocyte MII competence after 40 h. In standard IVM, heparin supplementation in pre-IVM did not affect MII competence; however, when heparin was combined with cAMP modulators, MII competence was significantly reduced from 65 to 15% (P < 0.05). In mouse experiments, heparin alone in pre-IVM significantly delayed germinal vesicle breakdown (GVBD) so that fewer GVBDs were observed at 0 and 1 h of IVM (P < 0.05), but not by 2 or 3 h of IVM. Combined treatment with IBMX and forskolin in the pre-IVM medium produced a large delay in GVBD such that no COCs exhibited GVBD in the first 1 h of IVM, and the addition of heparin in pre-IVM further significantly delayed the progression of GVBD (P < 0.05), in a dose-dependent manner (P < 0.01). Combined IBMX and forskolin treatment of mouse COCs during pre-IVM significantly increased mitochondrial membrane potential and ATP production in the oocyte at the end of pre-IVM (P < 0.05), and significantly improved fertilization, embryo development and quality (P < 0.05). However, heparin abolished the IBMX + forskolin-stimulated increase in mitochondrial membrane potential and ATP production (P < 0.05), and adversely affected embryonic cleavage, development rates and embryo quality (P < 0.05). This latter adverse combinational effect was negated when mouse COCs were collected in heparin and IBMX for 15 min, washed and then cultured for 45 min in IBMX and forskolin without heparin. Experiments in mice found that heparin ablation of the advantageous effects of cAMP modulators during pre-IVM was associated with altered oocyte metabolism, but the mechanism by which heparin affects metabolism remains unclear. This study has revealed a novel and unexpected interaction between heparin and cAMP modulators in pre-IVM in immature mouse and human oocytes, and established a means to collect oocytes using heparin while modulating oocyte cAMP to improve developmental potential.

Because subclinical hypothyroidism (thyroid-stimulating hormone [TSH] > 4.5 IU/mL) is associated with adverse pregnancy outcome, including early pregnancy loss, TSH is recommended to be titrated to ≤2.5 mIU/L in levothyroxine-treated women before pregnancy. The purpose of this study was to determine whether borderline-subclinical hypothyroidism (borderline-SCH; 2.5 < TSH ≤ 4.5 IU/mL) affects the outcome of subsequent pregnancies in women with unexplained recurrent pregnancy loss (uRPL). After workup for antinuclear antibody (ANA), anti-phospholipid syndrome, thrombophilia, uterine abnormalities, hormone disorders, and/or chromosomal abnormalities, 317 women with a history of uRPL were enrolled. The women were classified into two groups: borderline-SCH, and euthyroidism (0.3 ≤ TSH ≤ 2.5 IU/mL). All women had normal serum free thyroxine (T4) and did not receive levothyroxine before or during the subsequent pregnancy. There were no significant differences in age, number of previous pregnancy losses, number of live births, or body mass index between the borderline-SCH (n = 56) and the euthyroid (n = 261) groups, but the rate of ANA positivity differed significantly (53.6% vs 33.7%, respectively; P = 0.005). The subsequent pregnancy rate did not differ between the two groups (55.4%, 31/56 vs 51.3%, 134/261, respectively). The pregnancy loss rate (<22 weeks of gestation) tended to be higher in the borderline-SCH than the euthyroid group (29.0%, 9/31 vs 17.9%, 24/134), although not significantly so (P = 0.16). Although some subset of uRPL is though to be due to as-yet-unidentified cause(s), borderline-SCH is unlikely to be involved in uRPL. © 2017 Japan Society of Obstetrics and Gynecology.

Characterization of abdominal pain during methylnaltrexone treatment of opioid-induced constipation in advanced illness: a post hoc analysis of two clinical trials.

2011-11-01

Methylnaltrexone is a selective peripherally acting mu-opioid receptor antagonist that decreases the constipating effects of opioids without affecting centrally mediated analgesia. In two double-blind, placebo-controlled, Phase III studies of methylnaltrexone for opioid-induced constipation in patients with advanced illness, abdominal pain was the most common adverse event (AE) reported. This analysis sought to further characterize the Medical Dictionary for Regulatory Activities-defined abdominal pain AEs experienced in these studies. A post hoc analysis of verbatim descriptions was used to further assess AEs characterized as abdominal pain in both trials. Descriptive summary statistics were used to assess severity of abdominal pain, effect of abdominal pain on global pain scores, and other characteristics. Logistic regression analysis was used to determine the association of baseline characteristics with abdominal pain. Most verbatim descriptions of abdominal pain referred to "abdominal cramps" or "cramping." Abdominal pain AEs were mostly mild to moderate in severity and did not affect patients' global evaluation of pain. The incidence of abdominal pain AEs in methylnaltrexone-treated patients was greatest after the first dose and decreased with subsequent doses. No association between abdominal pain AEs and most baseline patient characteristics was noted. Abdominal pain AEs in methylnaltrexone-treated patients in clinical trials are usually described as "cramps" or "cramping," are mostly mild to moderate in severity, and decrease in incidence with subsequent dosing.

Does quinone or phenol enrichment of humic substances alter the primary compound from a non-algicidal to an algicidal preparation?

Dissolved organic matter (DOM) has been shown to affect phytoplankton species directly. These interactions largely depend on the origin and molecular size of DOM and are different in prokaryotes and eukaryotes. In a preceding study, however, two humic substance preparations did not adversely affect coccal green algae or cyanobacterial growth even at high concentrations of dissolved organic carbon (DOC). These results contradicted previous findings, showing a clear, negative response of different phototrophs to much lower DOC concentrations. To test whether or not at least defined building blocks of humic substances (HSs) are effective algicidal structures, we enriched two humic preparations with hydroquinone and p-benzoquinone, respectively, and exposed two different green algae, Pseudokirchneriella subcapitata and Monoraphidium braunii, and two cyanobacterial species, Synechocystis sp. and Microcystis aeruginosa, to the unmodified and enriched HSs. As response variables, growth rates in terms of biomass increase, chlorophyll-a content, and photosynthetic yield were measured. The highest concentration (4.17 mM DOC) of the modified HSs clearly inhibited growth; the cyanobacterial species were much more sensitive than the green algal species. However, realistic ecological concentrations did not adversely affect growth. Aerating the exposure solution for 24 h strongly reduced the inhibitory effect of the modified HSs. The algicidal effect was obviously caused by monomers and not by polymerised high molecular weight HSs themselves. Furthermore, the maximum quantum yield (Φ PSII max) was stimulated in the green algal species by low and medium DOC concentrations, but reduced in the cyanobacterial species upon exposure to higher HS concentrations. The quinone- and phenol-enriched HSs only showed algicidal activity at high concentrations of 4.17 mM DOC and lost their effects over time, presumably by oxidation and subsequent polymerisation. This study confirms that the applied humic substances themselves are not effective algicides even if enriched in effective structures. Copyright © 2012 Elsevier Ltd. All rights reserved.

Heat addition to a subsonic boundary layer: A preliminary analytical study

NASA Technical Reports Server (NTRS)

Macha, J. M.; Norton, D. J.

1971-01-01

A preliminary analytical study of the effects of heat addition to the subsonic boundary layer flow over a typical airfoil shape is presented. This phenomenon becomes of interest in the space shuttle mission since heat absorbed by the wing structure during re-entry will be rejected to the boundary layer during the subsequent low speed maneuvering and landing phase. A survey of existing literature and analytical solutions for both laminar and turbulent flow indicate that a heated surface generally destabilizes the boundary layer. Specifically, the boundary layer thickness is increased, the skin friction at the surface is decreased and the point of flow separation is moved forward. In addition, limited analytical results predict that the angle of attack at which a heated airfoil will stall is significantly less than the stall angle of an unheated wing. These effects could adversely affect the lift and drag, and thus the maneuvering capabilities of booster and orbiter shuttle vehicles.

Background Poor sleep contributes to adverse health outcomes making it important to understand sleep in medically vulnerable populations, including those with spinal cord injury (SCI). However, little attention has been paid to circumstances specific to SCI that may negatively impact sleep, or to consequences of poor sleep in this population. Objectives To examine the experience of sleep among individuals with SCI. Methodology Secondary analysis using thematic coding of qualitative data from an ethnographic study of community-dwelling adults with SCI. Results Sleep-related data were found in transcripts for 90% of the sample. Participants described diminished sleep duration and irregular sleep patterns. Several factors contributing to poor sleep were identified, including SCI-related circumstances and sleep environment. Participants also discussed how poor sleep affected occupational engagement. Conclusion This study highlights the extent of sleep disturbance experienced after SCI, the subsequent impact on occupational performance, and provides direction for clinical practice. PMID:28196449

In mammalian species, endometrial receptivity is driven by maternal factors independently of embryo signals. When pregnancy initiates, paracrine secretions of the preattachment embryo are essential both for maternal recognition and endometrium preparation for implantation and for coordinating development of embryonic and extraembryonic tissues of the conceptus. This review mainly focuses on domestic large animal species. We first illustrate the major steps of preattachment embryo development, including elongation in bovine, ovine, porcine, and equine species. We next highlight conceptus secretions that are involved in the communication between extraembryonic and embryonic tissues, as well as between the conceptus and the endometrium. Finally, we introduce experimental data demonstrating the intimate connection between conceptus secretions and endometrial activity and how adverse events perturbing this interplay may affect the progression of implantation that will subsequently impact pregnancy outcome, postnatal health, and expression of production traits in livestock offspring.

Astrocytic glycogen metabolism in the healthy and diseased brain.

2018-05-11

The brain contains a fairly low amount of glycogen, mostly located in astrocytes, a fact that has prompted the suggestion that glycogen does not have a significant physiological role in the brain. However, glycogen metabolism in astrocytes is essential for several key physiological processes and is adversely affected in disease. For instance, diminished ability to break down glycogen impinges on learning, and epilepsy, Alzheimer's disease, and type 2 diabetes are all associated with abnormal astrocyte glycogen metabolism. Glycogen metabolism supports astrocytic K + and neurotransmitter glutamate uptake and subsequent glutamine synthesis-three fundamental steps in excitatory signaling at most brain synapses. Thus, there is abundant evidence for a key role of glycogen in brain function. Here, we summarize the physiological brain functions that depend on glycogen, discuss glycogen metabolism in disease, and investigate how glycogen breakdown is regulated at the cellular and molecular levels. © 2018 by The American Society for Biochemistry and Molecular Biology, Inc.

Resistin role in development of gestational diabetes mellitus.

Siddiqui, Khalid; George, Teena P

Diabetes is estimated to be one of the major causes of deaths in most countries due to its high prevalence rate, which was 8.8% in 2015. Hyperglycemia detected during pregnancy is known as gestational diabetes mellitus and it increases the potential risk of development of Type 2 diabetes in mothers with its varying prevalence rate of 1-14% in different populations. It also leads to the higher risk of developing abnormal glucose tolerance and obesity in their child at an early age. Recent studies show that potential mediators of insulin resistance such as adipokines - adiponectin, leptin and resistin are important for glucose and lipid metabolism. Adipokines are directly involved in the regulation of insulin secretion and insulin sensitivity in the liver, muscle and adipose tissue. It is also involved in inflammation, adipose tissue accumulation, adverse fat distribution and subsequently affects glucose metabolism. This review highlights the role of resistin (an adipokine) in the development of gestational diabetes mellitus.

The ability to isolate specific, viable cell populations from mixed ensembles with minimal manipulation and within intra-operative time would provide significant advantages for autologous, cell-based therapies in regenerative medicine. Current cell-enrichment technologies are either slow, lack specificity and/or require labelling. Thus a rapid, label-free separation technology that does not affect cell functionality, viability or phenotype is highly desirable. Here, we demonstrate separation of viable from non-viable human stromal cells using remote dielectrophoresis, in which an electric field is coupled into a microfluidic channel using shear-horizontal surface acoustic waves, producing an array of virtual electrodes within the channel. This allows high-throughput dielectrophoretic cell separation in high conductivity, physiological-like fluids, overcoming the limitations of conventional dielectrophoresis. We demonstrate viable/non-viable separation efficacy of >98% in pre-purified mesenchymal stromal cells, extracted from human dental pulp, with no adverse effects on cell viability, or on their subsequent osteogenic capabilities.

Anomalous High Rainfall and Soil Saturation as Combined Risk Indicator of Rift Valley Fever Outbreaks, South Africa, 2008-2011.

Rift Valley fever (RVF), a zoonotic vectorborne viral disease, causes loss of life among humans and livestock and an adverse effect on the economy of affected countries. Vaccination is the most effective way to protect livestock; however, during protracted interepidemic periods, farmers discontinue vaccination, which leads to loss of herd immunity and heavy losses of livestock when subsequent outbreaks occur. Retrospective analysis of the 2008-2011 RVF epidemics in South Africa revealed a pattern of continuous and widespread seasonal rainfall causing substantial soil saturation followed by explicit rainfall events that flooded dambos (seasonally flooded depressions), triggering outbreaks of disease. Incorporation of rainfall and soil saturation data into a prediction model for major outbreaks of RVF resulted in the correctly identified risk in nearly 90% of instances at least 1 month before outbreaks occurred; all indications are that irrigation is of major importance in the remaining 10% of outbreaks.

Body composition, muscle capacity, and physical function in older adults: an integrated conceptual model.

PubMed

2014-07-01

The aging process leads to adverse changes in body composition (increases in fat mass and decreases in skeletal muscle mass), declines in physical function (PF), and ultimately increased risk for disability and loss of independence. Specific components of body composition or muscle capacity (strength and power) may be useful in predicting PF; however, findings have been mixed regarding the most salient predictor of PF. The development of a conceptual model potentially aids in understanding the interrelated factors contributing to PF with the factors of interest being physical activity, body composition, and muscle capacity. This article also highlights sex differences in these domains. Finally, factors known to affect PF, such as sleep, depression, fatigue, and self-efficacy, are discussed. Development of a comprehensive conceptual model is needed to better characterize the most salient factors contributing to PF and to subsequently inform the development of interventions to reduce physical disability in older adults.

Adverse prenatal environments can promote metabolic disease in offspring and subsequent generations. Animal models and epidemiological data implicate epigenetic inheritance, but the mechanisms remain unknown. In an intergenerational developmental programming model affecting F2 mouse metabolism, we demonstrate that the in utero nutritional environment of F1 embryos alters the germline DNA methylome of F1 adult males in a locus-specific manner. Differentially methylated regions are hypomethylated and enriched in nucleosome-retaining regions. A substantial fraction is resistant to early embryo methylation reprogramming, which may have an impact on F2 development. Differential methylation is not maintained in F2 tissues, yet locus-specific expression is perturbed. Thus, in utero nutritional exposures during critical windows of germ cell development can impact the male germline methylome, associated with metabolic disease in offspring.

Behavioral profiles are strongly shaped by an individual's whole life experience. The accumulation of negative experiences over lifetime is thought to promote anxiety-like behavior in adulthood (“allostatic load hypothesis”). In contrast, the “mismatch hypothesis” of psychiatric disease suggests that high levels of anxiety-like behavior are the result of a discrepancy between early and late environment. The aim of the present study was to investigate how different life histories shape the expression of anxiety-like behavior and modulate fear memory. In addition, we aimed to clarify which of the two hypotheses can better explain the modulation of anxiety and fear. For this purpose, male mice grew up under either adverse or beneficial conditions during early phase of life. In adulthood they were further subdivided in groups that either matched or mismatched the condition experienced before, resulting in four different life histories. The main results were: (i) Early life benefit followed by late life adversity caused decreased levels of anxiety-like behavior. (ii) Accumulation of adversity throughout life history led to impaired fear extinction learning. Late life adversity as compared to late life benefit mainly affected extinction training, while early life adversity as compared to early life benefit interfered with extinction recall. Concerning anxiety-like behavior, the results do neither support the allostatic load nor the mismatch hypothesis, but rather indicate an anxiolytic effect of a mismatched early beneficial and later adverse life history. In contrast, fear memory was strongly affected by the accumulation of adverse experiences over the lifetime, therefore supporting allostatic load hypothesis. In summary, this study highlights that anxiety-like behavior and fear memory are differently affected by specific combinations of adverse or beneficial events experienced throughout life.

A rape seed pollen-based diet was developed and found to be suitable for use in a dietary exposure assay for Propylea japonica. Using the diet, we established and validated a dietary exposure assay by using the protease inhibitor E-64 as positive control. Dose-dependent responses were documented for all observed life-table parameters of P. japonica including survival, pupation and eclosion rates, development time and adult weight. Results suggested that the dietary assay can detect the effects of insecticidal compounds on the survival and development of P. japonica. Using the established dietary assay, we subsequently tested the toxicity of Cry1Ab, Cry1Ac and Cry1F proteins that are expressed by transgenic maize, cotton or rice plants to P. japonica larvae. The diet containing E-64 was included as a positive control. Survival and development of P. japonica larvae were not adversely affected when the diet contained purified Cry1Ab, Cry1Ac, or Cry1F at 500 µg/g diet representing a worst-case exposure scenario. In contrast, P. japonica larvae were adversely affected when the diet contained E-64. The bioactivity and stability of the Cry proteins in the diet and Cry protein uptake by the ladybird larvae were confirmed by bioassay with a Cry-sensitive insect species and by ELISA. The current study describes a suitable experimental system for assessing the potential effects of gut-active insecticidal compounds on ladybird beetle larvae. The experiments with the Cry proteins demonstrate that P. japonica larvae are not sensitive to Cry1Ab, Cry1Ac and Cry1F.

Andean bear (Tremarctos ornatus) alopecia syndrome (ABAS) commonly affects captive bears, particularly sexually mature females. ABAS is characterized by bilaterally symmetrical predominantly flank alopecia with or without profound pruritus and secondary bacterial and Malassezia infections. There is no effective treatment and severely affected bears have been euthanized. This paper describes the successful management of ABAS in three female Andean bears. Skin biopsies and cytology revealed a mixed dermal inflammatory infiltrate, alopecia, hyperkeratosis, and Malassezia dermatitis. Allergen specific serology was positive for environmental allergens in one case. Hematology, serum biochemistry, and thyroid and adrenal function were normal in all cases. There was no consistent response to novel diet trials, antifungals, antihistamines, allergen specific immunotherapy, or topical antimicrobials. There was a partial response to ciclosporin (Atopica® cat, Novartis Animal Health; 5 mg/kg po, sid) in one case and oral glucocorticoids in all cases (dexamethasone sodium phosphate, [Colvasone 0.2%, Norbrook], 0.15 mg/kg po, sid or prednisolone [Deltacortene, Bruno Farmaceutici, and Megasolone 20, Coophavet], 0.3-1.2 mg/kg po, sid), but treatment was withdrawn following adverse effects. Treatment with oclacitinib maleate (Apoquel®, Zoetis; 0.46-0.5 mg/kg po, bid) resulted in rapid and complete resolution of the pruritus with subsequent improvement in demeanor and fur regrowth. After 5 mo, the bears were almost fully furred and off all other medication. Treatment was tapered to the lowest dose that prevented relapse of the pruritus (0.23-0.4 mg/kg po, sid). No adverse effects have been noted. ABAS is usually an intractable condition, and, to our knowledge, oclacitinib is the first treatment shown to result in sustained clinical improvement. Further studies on the etiology of ABAS, and on efficacy and long-term safety of oclacitinib are needed.

Committee Opinion No. 681: Disclosure and Discussion of Adverse Events.

PubMed

2016-12-01

Adverse outcomes, preventable or otherwise, are a reality of medical care. Most importantly, adverse events affect patients, but they also affect health care practitioners. Disclosing information about adverse events has benefits for the patient and the physician and, ideally, strengthens the patient-physician relationship and promotes trust. Studies show that after an adverse outcome, patients expect and want timely and full disclosure of the event, an acknowledgment of responsibility, an understanding of what happened, expressions of sympathy, and a discussion of what is being done to prevent recurrence. Surveys have shown that patients are less likely to pursue litigation if they perceive that the event was honestly disclosed. Barriers to full disclosure are many and include fear of retribution for reporting an adverse event, lack of training, a culture of blame, and fear of lawsuits. To reduce these concerns, it is recommended that health care facilities establish a nonpunitive, blame-free culture that encourages staff to report adverse events and near misses (close calls) without fear of retaliation. Health care institutions should have written policies that address the management of adverse events. Having a responsive process to inform and aid the patient, loved ones, and practitioners is required. A commitment on the part of all health care practitioners and institutions to establish programs and develop the tools needed to help patients, families, health care practitioners, and staff members deal with adversity is essential.

Toward Understanding How Early-Life Stress Reprograms Cognitive and Emotional Brain Networks.

PubMed

Chen, Yuncai; Baram, Tallie Z

Vulnerability to emotional disorders including depression derives from interactions between genes and environment, especially during sensitive developmental periods. Adverse early-life experiences provoke the release and modify the expression of several stress mediators and neurotransmitters within specific brain regions. The interaction of these mediators with developing neurons and neuronal networks may lead to long-lasting structural and functional alterations associated with cognitive and emotional consequences. Although a vast body of work has linked quantitative and qualitative aspects of stress to adolescent and adult outcomes, a number of questions are unclear. What distinguishes 'normal' from pathologic or toxic stress? How are the effects of stress transformed into structural and functional changes in individual neurons and neuronal networks? Which ones are affected? We review these questions in the context of established and emerging studies. We introduce a novel concept regarding the origin of toxic early-life stress, stating that it may derive from specific patterns of environmental signals, especially those derived from the mother or caretaker. Fragmented and unpredictable patterns of maternal care behaviors induce a profound chronic stress. The aberrant patterns and rhythms of early-life sensory input might also directly and adversely influence the maturation of cognitive and emotional brain circuits, in analogy to visual and auditory brain systems. Thus, unpredictable, stress-provoking early-life experiences may influence adolescent cognitive and emotional outcomes by disrupting the maturation of the underlying brain networks. Comprehensive approaches and multiple levels of analysis are required to probe the protean consequences of early-life adversity on the developing brain. These involve integrated human and animal-model studies, and approaches ranging from in vivo imaging to novel neuroanatomical, molecular, epigenomic, and computational methodologies. Because early-life adversity is a powerful determinant of subsequent vulnerabilities to emotional and cognitive pathologies, understanding the underlying processes will have profound implications for the world's current and future children.

Knowledge about the effects of early life adversity on kin relationships in later years is sparse. The purpose of this study was to examine if childhood abuse and adversity negatively influences emotional closeness with family in mid- and later life. A second goal was to determine the role of psychosocial resources and personality traits in buffering the effects of early adversities. Gender and cohort differences were explored to see if men were differentially affected than women and whether middle-aged adults (35-49 years old) were differentially affected than older adults (50-74 years old) by the effects of childhood abuse and adversity. Using retrospective accounts of early family abuse and adversities of 1,266 middle aged adults and 1,219 older adults from a large population-based survey, the National Survey of Midlife Development in United States (MIDUS), separate multiple regression analyses were conducted for the two cohorts to examine the effects of childhood emotional and physical abuse and family adversities on perceived emotional closeness with family. Interaction effects between childhood abuse and adversity (e.g., being expelled from school, death of sibling, parental divorce, losing a home to a natural disaster) with psychosocial resources (perceived control and self acceptance), personality characteristics (extraversion and neuroticism), and gender were examined. Results of OLS regressions suggest emotional and physical abuse predicted family closeness in middle-aged adults. Conversely, only emotional abuse predicted family closeness in older adults. Moderation models revealed that high levels of self acceptance were associated with better maintenance of emotional closeness among middle-aged adults who were emotionally and physically abused as children. Older adults with lower extraversion who experienced emotional abuse or reported greater number of adversities in childhood were found to be at higher risk for lower emotional closeness with family. Early life adversities were more detrimental for women. Findings suggest that the aftermath of childhood abuse does not dissipate with time, but continues to influence family relationships in mid- and later life. Identifying the links between childhood adversities and adult relationships can help identify strategic points for intervention to reduce the long-term effects of accumulated adverse experiences over the life course.

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.

Automatic detection of adverse events to predict drug label changes using text and data mining techniques.

The aim of this study was to assess the impact of automatically detected adverse event signals from text and open-source data on the prediction of drug label changes. Open-source adverse effect data were collected from FAERS, Yellow Cards and SIDER databases. A shallow linguistic relation extraction system (JSRE) was applied for extraction of adverse effects from MEDLINE case reports. Statistical approach was applied on the extracted datasets for signal detection and subsequent prediction of label changes issued for 29 drugs by the UK Regulatory Authority in 2009. 76% of drug label changes were automatically predicted. Out of these, 6% of drug label changes were detected only by text mining. JSRE enabled precise identification of four adverse drug events from MEDLINE that were undetectable otherwise. Changes in drug labels can be predicted automatically using data and text mining techniques. Text mining technology is mature and well-placed to support the pharmacovigilance tasks.

Wide variation in cardiopulmonary resuscitation interruption intervals among commercially available automated external defibrillators may affect survival despite high defibrillation efficacy.

PubMed

Snyder, David; Morgan, Carl

2004-09-01

Recent studies have associated interruptions of cardiopulmonary resuscitation imposed by automated external defibrillators (AEDs) with poor resuscitation outcome. In particular, the "hands-off" interval between precordial compressions and subsequent defibrillation shock has been implicated. We sought to determine the range of variation among current-generation AEDs with respect to this characteristic. Seven AEDs from six manufacturers were characterized via stopwatch and arrhythmia simulator with respect to the imposed hands-off interval. All AEDs were equipped with new batteries, and measurements were repeated five times for each AED. A wide variation in the hands-off interval between precordial compressions and shock delivery was observed, ranging from 5.2 to 28.4 secs, with only one AED achieving an interruption of <10 secs. Laboratory and clinical data suggest that this range of variation could be responsible for a more than two-fold variation in patient resuscitation success, an effect that far exceeds any defibrillation efficacy differences that may hypothetically exist. In addition to defibrillation waveform and dose, researchers should consider the hands-off cardiopulmonary resuscitation interruption interval between cardiopulmonary resuscitation and subsequent defibrillation shock to be an important covariate of outcome in resuscitation studies. Defibrillator design should minimize this interval to avoid potential adverse consequences on patient survival.

Childhood cancer survivors often experience complications related to cancer and its treatment that may adversely affect quality of life and increase the risk of premature death. The purpose of this manuscript is to review how data derived from Childhood Cancer Survivor Study (CCSS) investigations have facilitated identification of childhood cancer survivor populations at high risk for specific organ toxicity and secondary carcinogenesis and how this has informed clinical screening practices. Articles previously published that used the resource of the CCSS to identify risk factors for specific organ toxicity and subsequent cancers were reviewed and results summarized. CCSS investigations have characterized specific groups to be at highest risk of morbidity related to endocrine and reproductive dysfunction, pulmonary toxicity, cerebrovascular injury, neurologic and neurosensory sequelae, and subsequent neoplasms. Factors influencing risk for specific outcomes related to the individual survivor (eg, sex, race/ethnicity, age at diagnosis, attained age), sociodemographic status (eg, education, household income, health insurance) and cancer history (eg, diagnosis, treatment, time from diagnosis) have been consistently identified. These CCSS investigations that clarify risk for treatment complications related to specific treatment modalities, cumulative dose exposures, and sociodemographic factors identify profiles of survivors at high risk for cancer-related morbidity who deserve heightened surveillance to optimize outcomes after treatment for childhood cancer.

Kessler, Jörg

2018-01-01

Objectives To determine risk factors for short and long umbilical cord, entanglement and knot. Explore their associated risks of adverse maternal and perinatal outcome, including risk of recurrence in a subsequent pregnancy. To provide population based gestational age and sex and parity specific reference ranges for cord length. Design Population based registry study. Setting Medical Birth Registry of Norway 1999–2013. Population All singleton births (gestational age>22weeks<45 weeks) (n = 856 300). Methods Descriptive statistics and odds ratios of risk factors for extreme cord length and adverse outcomes based on logistic regression adjusted for confounders. Main outcome measures Short or long cord (<10th or >90th percentile), cord knot and entanglement, adverse pregnancy outcomes including perinatal and intrauterine death. Results Increasing parity, maternal height and body mass index, and diabetes were associated with increased risk of a long cord. Large placental and birth weight, and fetal male sex were factors for a long cord, which again was associated with a doubled risk of intrauterine and perinatal death, and increased risk of adverse neonatal outcome. Anomalous cord insertion, female sex, and a small placenta were associated with a short cord, which was associated with increased risk of fetal malformations, placental complications, caesarean delivery, non-cephalic presentation, perinatal and intrauterine death. At term, cord knot was associated with a quadrupled risk of perinatal death. The combination of a cord knot and entanglement had a more than additive effect to the association to perinatal death. There was a more than doubled risk of recurrence of a long or short cord, knot and entanglement in a subsequent pregnancy of the same woman. Conclusion Cord length is influenced both by maternal and fetal factors, and there is increased risk of recurrence. Extreme cord length, entanglement and cord knot are associated with increased risk of adverse outcomes including perinatal death. We provide population based reference ranges for umbilical cord length. PMID:29584790

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.

Stress in 1st-year women teachers: the context of social support and coping.

The effects of adverse work environments were examined in the context of other risk/protective factors in this extension of a short-term longitudinal study involving 184 newly appointed women teachers. Regression analyses revealed that-adjusting for preemployment levels of the outcomes and negative affectivity-social support and adversity in the fall work environment were among the factors that affected spring depressive symptoms, self-esteem, job satisfaction, and motivation to teach. Support from nonwork sources was directly related to future improved symptom levels and self-esteem; supervisor and colleague support were directly related to future job satisfaction. Effects of occupational coping, professional efficacy, locus of control, and school factors (e.g., special vs. regular education) were largely nonsignificant. Structural equation analyses indicated that adverse working conditions began to seriously affect the women soon after they started teaching.

Is there evidence that recent consolidation in the health insurance industry has adversely affected premiums?

PubMed

Kopit, William G

2004-01-01

James Robinson suggests that recent consolidation in the insurance market has been a cause of higher health insurance prices (premiums). Although the recent consolidation among health insurers and rising premiums are indisputable, it is unlikely that consolidation has had any adverse effect on premiums nationwide, and Robinson provides no data that suggest otherwise. Specifically, he does not present data showing an increase in concentration in any relevant market during the past few years, let alone any resulting increase in premiums. Health insurance consolidation in certain local markets could adversely affect premiums, but it seems clear that it is not a major national antitrust issue.

Weight-of-evidence evaluation of an adverse outcome ...

EPA Pesticide Factsheets

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

Objective: We examined the relationship of childhood exposure to adversity and risk of substance-use disorder in two culturally distinct American Indian reservation communities, exploring both the role of early initiation of substance use in mediating this relationship and variation in risk across types of adversity exposure. Method: The American Indian Service Utilization, Psychiatric Epidemiology, Risk and Protective Factors Project provided data from 2,927 American Indians on the occurrence and age at onset of adversities, substance use, and substance-use-disorder symptoms. Results: The risk of substance-use disorder associated with early adversity was explained partially by early initiation of substance use. Three types of adversity (major childhood events, traumas, and witnessed violence) were associated with early onset of substance use and increased risk of substance-use disorder. Gender and tribe were also related to variation in both early substance use and substance-use disorder. Conclusions: Early exposure to adverse events was associated with early substance use and the subsequent development of substance-use disorders among American Indians. Public health initiatives targeting substance use and substance-use disorders in American Indian communities should include efforts to help children in these communities cope with adversities they encounter.

Review on intrauterine programming: Consequences in rodent models of mild diabetes and mild fat overfeeding are not mild.

Jawerbaum, A; White, V

2017-04-01

An adverse intrauterine programming occurs in diabetes and obesity as the consequence of an adverse maternal environment that affects the appropriate fetoplacental development and growth. Experimental models of diabetes and fat overfeeding have provided relevant tools to address putative mechanisms of the adverse intrauterine programming. The current knowledge far extends from the original thoughts of the resulting intrauterine programming of metabolic and cardiovascular diseases to a full range of alterations that affect multiple tissues, organs, and systems that will compromise the long-life health of the offspring. This review examines the postnatal effects of rodent models of mild diabetes and fat overfeeding, identifying the multiple organ derangements in the offspring resulting from mild maternal adverse conditions. In addition, the comparison of experimental models of severe diabetes and fat overfeeding and the crucial role of the placenta are discussed, providing an update of the actual scenario of the putative mechanisms and adverse consequences of maternal metabolic derangements.

2004-07-01

This study presents quantitative, sociological models designed to account for cross-national variation in infant mortality rates. We consider variables linked to four different theoretical perspectives: the economic modernization, social modernization, political modernization, and dependency perspectives. The study is based on a panel regression analysis of a sample of 59 developing countries. Our preliminary analysis based on additive models replicates prior studies to the extent that we find that indicators linked to economic and social modernization have beneficial effects on infant mortality. We also find support for hypotheses derived from the dependency perspective suggesting that multinational corporate penetration fosters higher levels of infant mortality. Subsequent analysis incorporating interaction effects suggest that the level of political democracy conditions the effects of dependency relationships based upon exports, investments from multinational corporations, and international lending institutions. Transnational economic linkages associated with exports, multinational corporations, and international lending institutions adversely affect infant mortality more strongly at lower levels of democracy than at higher levels of democracy: intranational, political factors interact with the international, economic forces to affect infant mortality. We conclude with some brief policy recommendations and suggestions for the direction of future research.

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.

From the Cradle to the Grave: The Effect of Adverse Caregiving Environments on Attachment and Relationships Throughout the Lifespan

PubMed Central

Doyle, Colleen; Cicchetti, Dante

2017-01-01

This paper reviews research examining the effects of adverse early caregiving on relationships throughout the lifespan. Central attachment constructs are summarized and integrated into a review of research on the long-term effects of institutional rearing and child maltreatment. Findings are interpreted within the organizational perspective on development, which conceptualizes attachment as a stage-salient task of infancy that influences the reorganization of adaptive/maladaptive functioning around subsequent stage-salient tasks. Children who experience adverse early caregiving are more likely to exhibit aberrant attachment behaviors, deficits in social-emotional competencies, and persisting difficulties in social functioning and relationship outcomes. Disorganized attachment behavior stemming from adverse early caregiving has been a major focus of this work. Intervention efforts that target mental representations related to attachment relationships can facilitate improved social functioning. Clinical implications of this work are discussed.

2002-12-01

This study assessed characteristics of psychiatric patients for whom financial considerations affected the provision of "optimal" treatment. Psychiatrists reported that for 33.8 percent of 1,228 patients from a national sample, financial considerations such as managed care limitations, the patient's personal finances, and limitations inherent in the public care system adversely affected the provision of optimal treatment. Patients were more likely to have their treatment adversely affected by financial considerations if they were more severely ill, had more than one behavioral health disorder or a psychosocial problem, or were receiving treatment under managed care arrangements. Patients for whom financial considerations affect the provision of optimal treatment represent a population for whom access to treatment may be particularly important.

Childhood adversity, social support, and telomere length among perinatal women.

Adverse perinatal health outcomes are heightened among women with psychosocial risk factors, including childhood adversity and a lack of social support. Biological aging could be one pathway by which such outcomes occur. However, data examining links between psychosocial factors and indicators of biological aging among perinatal women are limited. The current study examined the associations of childhood socioeconomic status (SES), childhood trauma, and current social support with telomere length in peripheral blood mononuclear cells (PBMCs) in a sample of 81 women assessed in early, mid, and late pregnancy as well as 7-11 weeks postpartum. Childhood SES was defined as perceived childhood social class and parental educational attainment. Measures included the Childhood Trauma Questionnaire, Center for Epidemiologic Studies-Depression Scale, Multidimensional Scale of Perceived Social Support, and average telomere length in PBMCs. Per a linear mixed model, telomere length did not change across pregnancy and postpartum visits; thus, subsequent analyses defined telomere length as the average across all available timepoints. ANCOVAs showed group differences by perceived childhood social class, maternal and paternal educational attainment, and current family social support, with lower values corresponding with shorter telomeres, after adjustment for possible confounds. No effects of childhood trauma or social support from significant others or friends on telomere length were observed. Findings demonstrate that while current SES was not related to telomeres, low childhood SES, independent of current SES, and low family social support were distinct risk factors for cellular aging in women. These data have relevance for understanding potential mechanisms by which early life deprivation of socioeconomic and relationship resources affect maternal health. In turn, this has potential significance for intergenerational transmission of telomere length. The predictive value of markers of biological versus chronological age on birth outcomes warrants investigation. Copyright © 2017 Elsevier Ltd. All rights reserved.

To examine patterns of childhood adversity, their long-term consequences and the combined effect of different childhood adversity patterns as predictors of subsequent psychopathology. Secondary analysis of data from the US National Epidemiologic Survey on alcohol and related conditions. Using latent class analysis to identify childhood adversity profiles; and using multinomial logistic regression to validate and further explore these profiles with a range of associated demographic and household characteristics. Finally, confirmatory factor analysis substantiated initial latent class analysis findings by investigating a range of mental health diagnoses. Latent class analysis generated a three-class model of childhood adversity in which 60 % of participants were allocated to a low adversity class; 14 % to a global adversities class (reporting exposures for all the derived latent classes); and 26 % to a domestic emotional and physical abuse class (exposed to a range of childhood adversities). Confirmatory Factor analysis defined an internalising-externalising spectrum to represent lifetime reporting patterns of mental health disorders. Using logistic regression, both adversity groups showed specific gender and race/ethnicity differences, related family discord and increased psychopathology. We identified underlying patterns in the exposure to childhood adversity and associated mental health. These findings are informative in their description of the configuration of adversities, rather than focusing solely on the cumulative aspect of experience. Amelioration of longer-term negative consequences requires early identification of psychopathology risk factors that can inform protective and preventive interventions. This study highlights the utility of screening for childhood adversities when individuals present with symptoms of psychiatric disorders.

Severe Acute Local Reactions to a Hyaluronic Acid-derived Dermal Filler

2010-01-01

Injectable fillers are normally well tolerated by patients with little or no adverse effects. The most common side effects include swelling, redness, bruising, and pain at the injection site. This report describes three cases in which patients injected with a hyaluronic acid-derived injectable filler that is premixed with lidocaine developed adverse reactions including persistent swelling, pain, and nodule formation. Two of the three patients' abscesses were cultured for aerobic and anaerobic bacteria and mycobacterium. All three cultures were negative. Abscess persistence in all cases necessitated physical removal and/or enzymatic degradation with hyaluronidase. The effects subsided only after the product had been removed. Two of these patients were subsequently treated with other hyaluronic acid-derived dermal fillers without adverse events. PMID:20725567

Adverse perinatal conditions and the inner ear.

PubMed

Newton, V

2001-12-01

Epidemiological studies in a number of Western countries have attributed 6-14% of sensorineural hearing impairment from birth or early childhood to problems relating to the birth process [1-4]. In spite of this association it is not always clear in individual instances whether adverse perinatal conditions identified subsequently have been causative of a hearing loss or not. It is possible that the hearing impairment was the consequence of an earlier intrauterine insult or is a coincidental finding. Infants carrying genetic mutations for hearing loss may coincidentally experience perinatal stress. It is therefore important to investigate the cause of a hearing loss discovered in infancy irrespective of the history of the infant having experienced adverse conditions surrounding the time of birth.

OBJECTIVES: Patients with cancer who are treated with chemotherapy report adverse events during their treatment, which can affect their quality of life and increase the likelihood that their treatment will not be completed. In this study, patients' perceptions of the physician-patient relationship and communication about cancer-related issues, particularly adverse events were examined. METHODS: We surveyed 508 patients with cancer concerning the occurrence of adverse events and their relationship and communication with their physicians regarding cancer, treatment, and adverse events. RESULTS: Most individuals surveyed (>90%) discussed diagnosis, treatment plan, goals, and schedule, and potential adverse events with their physicians before initiating chemotherapy; approximately 75% of these individuals understood these topics completely or very well. Physician-patient discussions of adverse events were common, with tiredness, nausea and vomiting, and loss of appetite discussed prior to chemotherapy in over 80% of communications. These events were also the most often experienced (ranging in 95% to 64% of the respondents) along with low white blood cell counts (WBCs), which were experienced in 67% of respondents. Approximately 75% of the individuals reported that their overall quality of life was affected by adverse events. CONCLUSIONS: These findings suggest that discussions alone do not provide patients with sufficient understanding of the events, nor do they appear to adequately equip patients to cope with them. Therefore, efforts to improve cancer care should focus on developing tools to improve patients' understanding of the toxicities of chemotherapy, as well as providing resources to reduce the effects of adverse events.

Raposa, Elizabeth B; Hammen, Constance L; Brennan, Patricia A

2015-01-01

Past research has highlighted the negative impact of early adverse experiences on childhood social functioning, including friendship selection, and later mental health. The current study explored the long-term effects of early adversity on young adults' close friends' psychological symptoms and the impact of these close friendships on later depressive symptoms. A prospective longitudinal design was used to examine 816 youth from a large community-based sample, who were followed from birth through age 25. Participants' mothers provided contemporaneous information about adversity exposure up to age 5, and participants completed questionnaires about their own depressive symptoms at age 20 and in their early 20s. Youth also nominated a best friend to complete questionnaires about his or her own psychopathology at age 20. Individuals who experienced more early adversity by age 5 had best friends with higher rates of psychopathology at age 20. Moreover, best friends' psychopathology predicted target youth depressive symptoms 2 to 5 years later. Results indicate that early adversity continues to affect social functioning throughout young adulthood and that best friendships marked by elevated psychopathology in turn negatively affect mental health. Findings have implications for clinical interventions designed to prevent the development of depressive symptoms in youth who have been exposed to early adversity.

Early adversity, in the form of abuse, neglect, socioeconomic status and other adverse experiences, is associated with poor physical and mental health outcomes. To understand the biologic mechanisms underlying these associations, studies have evaluated the relationship between early adversity and telomere length, a marker of cellular senescence. Such results have varied in regard to the size and significance of this relationship. Using meta-analytic techniques, we aimed to clarify the relationship between early adversity and telomere length while exploring factors affecting the association, including adversity type, timing and study design. A comprehensive search in July 2016 of PubMed/MEDLINE, PsycINFO and Web of Science identified 2462 studies. Multiple reviewers appraised studies for inclusion or exclusion using a priori criteria; 3.9% met inclusion criteria. Data were extracted into a structured form; the Newcastle-Ottawa Scale assessed study quality, validity and bias. Forty-one studies (N=30 773) met inclusion criteria. Early adversity and telomere length were significantly associated (Cohen's d effect size=-0.35; 95% CI, -0.46 to -0.24; P<0.0001). Sensitivity analyses revealed no outlier effects. Adversity type and timing significantly impacted the association with telomere length (P<0.0001 and P=0.0025, respectively). Subgroup and meta-regression analyses revealed that medication use, medical or psychiatric conditions, case-control vs longitudinal study design, methodological factors, age and smoking significantly affected the relationship. Comprehensive evaluations of adversity demonstrated more extensive telomere length changes. These results suggest that early adversity may have long-lasting physiological consequences contributing to disease risk and biological aging.

2015-10-01

Adverse drug reactions are a common problem affecting adults and children. The economic impact of the adverse drug reactions has been widely evaluated; however, studies of the impact on the quality of life of children with adverse drug reactions are scarce. The aim was to evaluate studies assessing the health-related quality of life of children with adverse drug reactions. We conducted a systematic review that included the following electronic databases: MEDLINE, EMBASE and the Cochrane Library (including the Cochrane Database of Systematic Reviews, the Database of Abstracts of Reviews of Effects, the Cochrane Controlled Trials Register and the Health Technology Assessment Databases). Nine studies were included. Four of the studies were conducted in children with epilepsy; the rest of them involved children with chronic viral hepatitis, Crohn's disease, paediatric cancer and multiple adverse drug reactions compared with healthy children. Based on their findings, authors of all studies concluded that adverse drug reactions had a negative impact on the quality of life of children. No meta-analysis was conducted given the heterogeneous nature of the studies. To date, there is no specific instrument that measures quality of life of children with adverse drug reactions, and the information available is poor and variable. In general, adverse drug reactions have a negative impact on the quality of life of affected children. For those interested in this area, more work needs to be done to improve tools that help to evaluate efficiently the health-related quality of life of children with adverse drug reactions and chronic diseases. © 2014 The British Pharmacological Society.

2012-09-01

This paper is a report of a study conducted to test three hypotheses derived from an integral conceptual model of frailty.   The integral model of frailty describes the pathway from life-course determinants to frailty to adverse outcomes. The model assumes that life-course determinants and the three domains of frailty (physical, psychological, social) affect adverse outcomes, the effect of disease(s) on adverse outcomes is mediated by frailty, and the effect of frailty on adverse outcomes depends on the life-course determinants. In June 2008 a questionnaire was sent to a sample of community-dwelling people, aged 75 years and older (n = 213). Life-course determinants and frailty were assessed using the Tilburg frailty indicator. Adverse outcomes were measured using the Groningen activity restriction scale, the WHOQOL-BREF and questions regarding healthcare utilization. The effect of seven self-reported chronic diseases was examined. Life-course determinants, chronic disease(s), and frailty together explain a moderate to large part of the variance of the seven continuous adverse outcomes (26-57%). All these predictors together explained a significant part of each of the five dichotomous adverse outcomes. The effect of chronic disease(s) on all 12 adverse outcomes was mediated at least partly by frailty. The effect of frailty domains on adverse outcomes did not depend on life-course determinants. Our finding that the adverse outcomes are differently and uniquely affected by the three domains of frailty (physical, psychological, social), and life-course determinants and disease(s), emphasizes the importance of an integral conceptual model of frailty. © 2011 Blackwell Publishing Ltd.

Effects of early-life adversity on immune function are mediated by prenatal environment: Role of prenatal alcohol exposure.

2017-11-01

The contribution of the early postnatal environment to the pervasive effects of prenatal alcohol exposure (PAE) is poorly understood. Moreover, PAE often carries increased risk of exposure to adversity/stress during early life. Dysregulation of immune function may play a role in how pre- and/or postnatal adversity/stress alters brain development. Here, we combine two animal models to examine whether PAE differentially increases vulnerability to immune dysregulation in response to early-life adversity. PAE and control litters were exposed to either limited bedding (postnatal day [PN] 8-12) to model early-life adversity or normal bedding, and maternal behavior and pup vocalizations were recorded. Peripheral (serum) and central (amygdala) immune (cytokines and C-reactive protein - CRP) responses of PAE animals to early-life adversity were evaluated at PN12. Insufficient bedding increased negative maternal behavior in both groups. Early-life adversity increased vocalization in all animals; however, PAE pups vocalized less than controls. Early-life adversity reduced serum TNF-α, KC/GRO, and IL-10 levels in control but not PAE animals. PAE increased serum CRP, and levels were even higher in pups exposed to adversity. Finally, PAE reduced KC/GRO and increased IL-10 levels in the amygdala. Our results indicate that PAE alters immune system development and both behavioral and immune responses to early-life adversity, which could have subsequent consequences for brain development and later life health.

Childhood Adversity and Pain Sensitization.

PubMed

You, Dokyoung Sophia; Meagher, Mary W

Childhood adversity is a vulnerability factor for chronic pain. However, the underlying pain mechanisms influenced by childhood adversity remain unknown. The aim of the current study was to evaluate the impact of childhood adversity on dynamic pain sensitivity in young adults. After screening for childhood adverse events and health status, healthy individuals reporting low (below median; n = 75) or high levels of adversity (the top 5%; n = 51) were invited for pain testing. Both groups underwent heat pain threshold and temporal summation of second pain (TSSP) testing after reporting depressive symptoms. TSSP refers to a progressive increase in pain intensity with repetition of identical noxious stimuli and is attributed to central sensitization. Changes in pain ratings over time (slope) were computed for TSSP sensitization and decay of subsequent aftersensations. The high-adversity group showed greater TSSP sensitization (meanslope, 0.75; SDpositive slope, 1.78), and a trend toward a slower decay (meanslope, -11.9; SD, 3.4), whereas the low-adversity group showed minimal sensitization (meanslope, 0.07; SDnear-zero slope, 1.77), F(1,123) = 5.84, p = .017 and faster decay (meanslope, -13.1; SD, 3.4), F(1,123) = 3.79, p = .054. This group difference remained significant even after adjusting for adult depressive symptoms (p = .033). No group difference was found in heat pain threshold (p = .85). Lastly, the high-adversity group showed blunted cardiac and skin conductance responses. These findings suggest that enhancement of central sensitization may provide a mechanism underlying the pain hypersensitivity and chronicity linked to childhood adversity.

Background. Renal hyperparathyroidism (RHPT) is a serious complication of long-term dialysis treatment. Two intervention methods can be administered to treat RHPT, namely percutaneous ethanol injection therapy (PEIT) and a parathyroidectomy (PTx). PEIT is associated with a significant adverse event, adhesion formation. This study was performed to investigate the effect of PEIT on subsequent PTx. Methods. A total of 80 subjects were included in the study. The patients had a diagnosis of RHPT for which surgery was indicated. They were divided according to whether they underwent PEIT (PEIT group) or not (non-PEIT group). The outcomes of PTx following PEIT were evaluated. Results. There were 19 patients in the PEIT group and 61 in the non-PEIT group. The operation time was significantly longer in the PEIT group but no significant differences in the amount of bleeding or frequency of recurrent nerve paralysis were observed. The intact PTH levels immediately following surgery were slightly higher in the PEIT group. The postoperative intact PTH levels were found to be significantly higher in those who received two or more courses of PEIT. The number of patients with an intact PTH level >60 pg/ml on postoperative Day 1 was significantly higher in the PEIT group. Conclusions. These findings suggested that PEIT prior to PTx can affect the subsequent surgical outcome due to associated adhesions and dissemination. For patients with a possibility of either a decreased efficacy or a lack of efficacy for PEIT, it is therefore important to consider PTx from the very beginning of the treatment. PMID:25983972

The dark side of transparency: How and when pay administration practices affect employee helping.

PubMed

Bamberger, Peter; Belogolovsky, Elena

2017-04-01

This study examines a long-standing contention of practitioners and scholars alike, namely that pay transparency may adversely affect employees' tendency to offer assistance to coworkers. Drawing from research on social comparison, information vividness, and envy, we develop and test a moderated-mediation model positing that transparency adversely affects the amount of help individuals afford to peers who, based on pay for performance, are paid more than them. Testing our hypotheses in the context of a multiround simulation-based laboratory experiment, we find that this adverse effect of pay transparency on helping is largely explained by transparency's positive association with episodic envy, but only when individual differences grounded in differential social value orientations, specifically those regarding individualism beliefs and prosocial motivation, are taken into consideration. Implications for theory and practice are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Early detection of and intervention in childhood adversity has powerful potential to improve the health and well-being of children. A systematic review was conducted to better understand the pediatric health outcomes associated with childhood adversity. PubMed, PsycArticles, and CINAHL were searched for relevant articles. Longitudinal studies examining various adverse childhood experiences and biological health outcomes occurring prior to age 20 were selected. Mental and behavioral health outcomes were excluded, as were physical health outcomes that were a direct result of adversity (i.e. abusive head trauma). Data were extracted and risk of bias was assessed by 2 independent reviewers. After identifying 15940 records, 35 studies were included in this review. Selected studies indicated that exposure to childhood adversity was associated with delays in cognitive development, asthma, infection, somatic complaints, and sleep disruption. Studies on household dysfunction reported an effect on weight during early childhood, and studies on maltreatment reported an effect on weight during adolescence. Maternal mental health issues were associated with elevated cortisol levels, and maltreatment was associated with blunted cortisol levels in childhood. Furthermore, exposure to childhood adversity was associated with alterations of immune and inflammatory response and stress-related accelerated telomere erosion. Childhood adversity affects brain development and multiple body systems, and the physiologic manifestations can be detectable in childhood. A history of childhood adversity should be considered in the differential diagnosis of developmental delay, asthma, recurrent infections requiring hospitalization, somatic complaints, and sleep disruption. The variability in children's response to adversity suggests complex underlying mechanisms and poses a challenge in the development of uniform diagnostic guidelines. More large longitudinal studies are needed to better understand how adversity, its timing and severity, and the presence of individual genetic, epigenetic, and protective factors affects children's health and development.

Adverse childhood experiences are significant risk factors for physical and mental illnesses in adulthood. Traumatic brain injury/concussion is a challenging condition where pre-injury factors may affect recovery. The association between childhood adversity and traumatic brain injury/concussion has not been previously reviewed. The research question addressed is: What is known from the existing literature about the association between adverse childhood experiences and traumatic brain injury/concussion in adults? All original studies of any type published in English since 2007 on adverse childhood experiences and traumatic brain injury/concussion outcomes were included. The literature search was conducted in multiple electronic databases. Arksey and O'Malley and Levac et al.'s scoping review frameworks were used. Two reviewers independently completed screening and data abstraction. The review yielded six observational studies. Included studies were limited to incarcerated or homeless samples, and individuals at high-risk of or with mental illnesses. Across studies, methods for childhood adversity and traumatic brain injury/concussion assessment were heterogeneous. A positive association between adverse childhood experiences and traumatic brain injury occurrence was identified. The review highlights the importance of screening and treatment of adverse childhood experiences. Future research should extend to the general population and implications on injury recovery. Implications for rehabilitation Exposure to adverse childhood experiences is associated with increased risk of traumatic brain injury. Specific types of adverse childhood experiences associated with risk of traumatic brain injury include childhood physical abuse, psychological abuse, household member incarceration, and household member drug abuse. Clinicians and researchers should inquire about adverse childhood experiences in all people with traumatic brain injury as pre-injury health conditions can affect recovery.

Psychological responses, coping and supporting needs of healthcare professionals as second victims.

To provide an overview of healthcare professionals' psychological responses, coping strategies and supporting needs in the aftermath of an adverse event, thus informing health policy implications and future research in this aspect. Trauma experienced by healthcare professionals as second victims potentially provokes intense emotional distress, detrimental professional outcomes and imposes harsh long-term effects. A systematic literature review was performed to synthesize the experiences and needs of second victims who are healthcare professionals being traumatized by an unanticipated adverse event, medical error or patient-related injury. CINAHL, Embase, PsycINFO, PubMed and Scopus databases were searched for relevant articles published in English from January 2000 to October 2015. Data extraction was performed for the 30 studies selected. Second victims experienced enduring intense negative psychological responses. They adopted multiple coping mechanisms and desired emotional and informational support. Second victims experience substantial psychological impact which can be mitigated with supportive environments. It is imperative that subsequent research consider the potential factors affecting second victims' emotional experience, efficacy of coping strategies in facilitating recovery and obtain a comprehensive understanding of second victims' experience. Nursing and health management's role in establishing organizational support structures is necessary to meet second victims' needs. This existing knowledge is significant to guide policy makers in developing a holistic and effective second victim support programme. © 2016 International Council of Nurses.

Are obstetric outcomes affected by female genital mutilation?

PubMed

2018-03-01

Female genital mutilation (FGM) has been associated with adverse obstetric and neonatal outcomes, such as postpartum haemorrhage (PPH), perineal trauma, genital fistulae, obstructed labour and stillbirth. The prevalence of FGM has increased in the UK over the last decade. There are currently no studies available that have explored the obstetric impact of FGM in the UK. The aim of our study was to investigate the obstetric and neonatal outcomes of women with FGM when compared with the general population. We conducted a retrospective case-control study of consecutive pregnant women with FGM over a 5-year period between 1 January 2009 and 31 December 2013. Each woman with FGM was matched for age, ethnicity, parity and gestation with subsequent patients without FGM (control cohort) over the same 5-year period. Outcomes assessed were mode of delivery, duration of labour, estimated blood loss, analgaesia, perineal trauma and foetal outcomes. A total of 242 eligible women (121 FGM, 121 control) were identified for the study. There was a significant increase in the use of episiotomy in the FGM group (p = 0.009) and a significant increase in minor PPH in the control group during caesarean sections (p = 0.0001). There were no differences in all other obstetric and neonatal parameters. In our unit, FGM was not associated with an increased incidence of adverse obstetric and foetal morbidity or mortality.

Optical probes to identify tumor margins in vivo would greatly reduce the time, effort and complexity in the surgical removal of malignant tissue in head and neck cancers. Current approaches involve visual microscopy of stained tissue samples to determine cancer margins, which results in the excision of excess of tissue to assure complete removal of the cancer. Such surgical procedures and follow-on chemotherapy can adversely affect the patient's recovery and subsequent quality of life. In order to reduce the complexity of the process and minimize adverse effects on the patient, we investigate ex vivo tissue samples (stained and unstained) using digital holographic microscopy in conjunction with spectroscopic analyses (reflectance and transmission spectroscopy) in order to determine label-free, optically identifiable characteristic features that may ultimately be used for in vivo processing of cancerous tissues. The tissue samples studied were squamous cell carcinomas and associated controls from patients of varying age, gender and race. Holographic microscopic imaging scans across both cancerous and non-cancerous tissue samples yielded amplitude and phase reconstructions that were correlated with spectral signatures. Though the holographic reconstructions and measured spectra indicate variations even among the same class of tissue, preliminary results indicate the existence of some discriminating features. Further analyses are presently underway to further this work and extract additional information from the imaging and spectral data that may prove useful for in vivo surgical identification.

the change in lifestyle and nutrition has led to growing obesity; in Mexico there has been significant increase in its prevalence. The problem was thought limited to adult population, but it also affects children, adolescents and young adults. Obesity at an early stage of life, subsequently leads to obesity in adult life. Apparently few attempts with College students have being reported. relate the effect of anthropometry and physical condition with dietary habits, physical activity and smoking addiction in students of a public university of Mexico, in order to establish a diagnosis of their nutritional status. one hundred and seventy eight students, were measured obtaining: body weight, height, waist and hip circumference, body composition and blood pressure. A questionnaire to determine their physical activity was applied, a dietary assessment was also collected and socioeconomic status was established. Data were analyzed statistically by the method of least squares. individuals classified as over-weighted, with obesity class 1 and class 2, accounted for 48.87% of the total population; more overweight and obesity was found in men compared with women, affecting negatively the value of blood pressure. This deteriorating health was attributable to poor eating habits: skipping breakfast and consumption of fast food. Smoking was revealed as a major risk factor since it adversely affected nutritional status. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

DNA repair efficiency in germ cells and early mouse embryos and consequences for radiation-induced transgenerational genomic damage

DOE Office of Scientific and Technical Information (OSTI.GOV)

Marchetti, Francesco; Wyrobek, Andrew J.

Exposure to ionizing radiation and other environmental agents can affect the genomic integrity of germ cells and induce adverse health effects in the progeny. Efficient DNA repair during gametogenesis and the early embryonic cycles after fertilization is critical for preventing transmission of DNA damage to the progeny and relies on maternal factors stored in the egg before fertilization. The ability of the maternal repair machinery to repair DNA damage in both parental genomes in the fertilizing egg is especially crucial for the fertilizing male genome that has not experienced a DNA repair-competent cellular environment for several weeks prior to fertilization.more » During the DNA repair-deficient period of spermatogenesis, DNA lesions may accumulate in sperm and be carried into the egg where, if not properly repaired, could result in the formation of heritable chromosomal aberrations or mutations and associated birth defects. Studies with female mice deficient in specific DNA repair genes have shown that: (i) cell cycle checkpoints are activated in the fertilized egg by DNA damage carried by the sperm; and (ii) the maternal genotype plays a major role in determining the efficiency of repairing genomic lesions in the fertilizing sperm and directly affect the risk for abnormal reproductive outcomes. There is also growing evidence that implicates DNA damage carried by the fertilizing gamete as a mediator of postfertilization processes that contribute to genomic instability in subsequent generations. Transgenerational genomic instability most likely involves epigenetic mechanisms or error-prone DNA repair processes in the early embryo. Maternal and embryonic DNA repair processes during the early phases of mammalian embryonic development can have far reaching consequences for the genomic integrity and health of subsequent generations.« less

To evaluate the association between adverse childhood experiences - e.g. abuse, neglect, domestic violence and parental separation, substance use, mental illness or incarceration - and the health of young adults in eight eastern European countries. Between 2010 and 2013, adverse childhood experience surveys were undertaken in Albania, Latvia, Lithuania, Montenegro, Romania, the Russian Federation, The former Yugoslav Republic of Macedonia and Turkey. There were 10,696 respondents - 59.7% female - aged 18-25 years. Multivariate modelling was used to investigate the relationships between adverse childhood experiences and health-harming behaviours in early adulthood including substance use, physical inactivity and attempted suicide. Over half of the respondents reported at least one adverse childhood experience. Having one adverse childhood experience increased the probability of having other adverse childhood experiences. The number of adverse childhood experiences was positively correlated with subsequent reports of health-harming behaviours. Compared with those who reported no adverse experiences, respondents who reported at least four adverse childhood experiences were at significantly increased risk of many health-harming behaviours, with odds ratios varying from 1.68 (95% confidence interval, CI: 1.32-2.15) - for physical inactivity - to 48.53 (95% CI: 31.98-76.65) - for attempted suicide. Modelling indicated that prevention of adverse childhood experiences would substantially reduce the occurrence of many health-harming behaviours within the study population. Our results indicate that individuals who do not develop health-harming behaviours are more likely to have experienced safe, nurturing childhoods. Evidence-based programmes to improve parenting and support child development need large-scale deployment in eastern European.

Neighborhood cohesion and daily well-being: Results from a diary study

Neighborly cohesiveness has documented benefits for health. Furthermore, high perceived neighborhood cohesion offsets the adverse health effects of neighborhood socioeconomic adversity. One potential way neighborhood cohesion influences health is through daily stress processes. The current study uses participants (n = 2022, age 30–84 years) from The Midlife in the United States II and the National Study of Daily Experiences II, collected between 2004–2006, to examine this hypothesis using a within-person, daily diary design. We predicted that people who perceive high neighborhood cohesion are exposed to fewer daily stressors, such as interpersonal arguments, lower daily physical symptoms and negative affect, and higher daily positive affect. We also hypothesized that perceptions of neighborhood cohesion buffer declines in affective and physical well-being on days when daily stressors do occur. Results indicate that higher perceived neighborhood cohesion predicts fewer self-reported daily stressors, higher positive affect, lower negative affect, and fewer physical health symptoms. High perceived neighborhood cohesion also buffers the effects of daily stressors on negative affect, even after adjusting for other sources of social support. Results from the present study suggest interventions focusing on neighborhood cohesion may result in improved well-being and may minimize the adverse effect of daily stressors. PMID:24034965

The long-term consequence of experiencing mental health problems may lead to several adverse outcomes. The current study aims to validate previous identified trajectories of mental health problems from 1993 to 2006 in women by examining their implications on subsequent work and family-related outcomes in 2011. Employed women (n = 439) with children were drawn from the Tracking Opportunities and Problems-Study (TOPP), a community-based longitudinal study following Norwegian families across 18 years. Previous identified latent profiles of mental health trajectories (i.e., High; Moderate; Low-rising and Low levels of mental health problems over time) measured at six time points between 1993 and 2006 were examined as predictors of burnout (e.g., exhaustion and disengagement from work) and work-family conflict in 2011 in univariate and multivariate analyses of variance adjusted for potential confounders (age, job demands, and negative emotionality). We found that having consistently High and Moderate symptoms as well as Low-Rising symptoms from 1993 to 2006 predicted higher levels of exhaustion, disengagement from work and work-family conflict in 2011. Findings remained unchanged when adjusting for several potential confounders, but when adjusting for current mental health problems only levels of exhaustion were predicted by the mental health trajectories. The study expands upon previous studies on the field by using a longer time span and by focusing on employed women with children who experience different patterns of mental health trajectories. The long-term effect of these trajectories highlight and validate the importance of early identification and prevention in women experiencing adverse patterns of mental health problems with regards to subsequent work and family-related outcomes.

Deaths and severe adverse events associated with anesthesia-assisted rapid opioid detoxification--New York City, 2012.

PubMed

2013-09-27

During August-September 2012, the New York City Department of Health and Mental Hygiene (DOHMH) was notified by the New York City Poison Control Center regarding three patients who experienced serious adverse events after anesthesia-assisted rapid opiate detoxification (AAROD) at a local outpatient clinic. All three patients required hospitalization, and one subsequently died. DOHMH issued an order requiring that the clinic cease performing AAROD pending an investigation and searched for additional cases of AAROD-related serious adverse events at the clinic and elsewhere in New York City for the period September 2011 to September 2012. That search found no serious adverse events at clinics other than the one implicated. Of the 75 patients who underwent AAROD at the implicated clinic during January-September 2012, two died, and five others experienced serious adverse events requiring hospitalization. As a result of the findings, the New York State Department of Health, the New York Office of Alcoholism and Substance Abuse Services, and DOHMH jointly issued a Health Alert informing New York health-care providers of AAROD-associated serious adverse events and recommending that they avoid use of AAROD in favor of evidence-based options for opioid dependence treatment.

The effect of presentation level on memory performance.

A loss of speech intelligibility at high presentation levels is called rollover. It is a phenomenon that increases in prevalence as people age. Whether the adverse effect of high presentation levels extends to processes subsequent to speech intelligibility, such as memory, is unknown. The present study examined this question on the basis of the previous finding that older but not younger adults showed memory impairment when acoustically distorted words were presented at 50 dB SL compared with an undistorted baseline presented at 65 dB SPL. One question investigated in the present study was whether a presentation level of 50 dB SL put older listeners at the cusp of rollover and whether this subsequently impaired memory. Moreover, we wanted to know whether and at what level it was possible to induce a similar impairment in younger listeners. We used a paired-associate memory paradigm in which five word pairs per list were presented at a rate of 4 secs per word pair. After each list, the first word of one of the pairs was presented again and the listener was asked to recall the second word. Over the course of the experiment, all list positions were tested an equal number of times. The word pairs, which were acoustically distorted using a jittering algorithm, were presented at 40 dB SL to all younger and older participants and just below an uncomfortably loud level for younger listeners only. Intelligibility of the distorted words was equated across age groups for each presentation level. The effect of presentation level on memory performance was investigated and compared with data of a previous study that used the same design but presented the distorted and undistorted words at 50 dB SL to both age groups. A total of 58 younger and 24 older adults were tested in two experiments. The results showed that for older adults, memory performance for distorted words was decreased in all list positions at a presentation level of 50 dB SL compared with 40 dB SL and an undistorted 65 dB SPL baseline. This effect did not occur for younger listeners. However, when younger adults were tested at a very high presentation level, they showed the same memory decrease compared with the baseline as older adults showed for 50 dB SL. A high presentation level of distorted words can adversely affect memory even after intelligibility is equated for. Moreover, older listeners are affected at lower presentation levels. Hence, the choice of sound level, particularly for older listeners, is important and may affect their level of cognitive performance beyond its effects on intelligibility. Higher presentation levels may not always lead to better performance when the task involves recall of words previously heard.

Potential Adverse Effects of Violent Video Gaming: Interpersonal- Affective Traits Are Rather Impaired Than Disinhibition in Young Adults.

The increasing trend of mass shootings, which were associated with excessive use of violent video games, fueled the debate of possible effects violent video games may have on adolescents and young adults. The aim of this study was to investigate the possible link between violent video gaming effects and the disposition of adverse behavior traits such as interpersonal-affective deficits and disinhibition. Data of 167 young adults, collected by an online questionnaire battery, were analyzed for lifetime video game exposure differences (i.e., non-gamers, non-violent video gamers, stopped violent video game users, and ongoing violent video game users) as well as for recent exposure effects on adverse behavior traits (Levenson's Psychopathy Scale), while controlling for other potentially confounding lifestyle factors. While interpersonal-affective deficits were significantly higher in participants with ongoing violent video game exposure compared to non-gamers and non-violent video gamers, disinhibition was significantly higher in both - stopped and ongoing - violent video game exposure groups compared to non-gamers. Recent violent video game exposure was a stronger predictor for interpersonal-affective deficits, but was also significant for disinhibition. Considering that we observed small to medium effects in a sample of young adults with little to moderate use of violent video games highlights the importance of further investigating the potential adverse effects of violent video games on quality of social relationships.

Exposure to early adversity: Points of cross-species translation that can lead to improved understanding of depression.

PubMed

Andersen, Susan L

2015-05-01

The relationship between developmental exposure to adversity and affective disorders is reviewed. Adversity discussed herein includes physical and sexual abuse, neglect, or loss of a caregiver in humans. While these stressors can occur at any point during development, the unique temporal relationship to specific depressive symptoms was the focus of discussion. Further influences of stress exposure during sensitive periods can vary by gender and duration of abuse as well. Data from animal studies are presented to provide greater translational and causal understanding of how sensitive periods, different types of psychosocial stressors, and sex interact to produce depressive-like behaviors. Findings from maternal separation, isolation rearing, chronic variable stress, and peer-peer rearing paradigms clarify interpretation about how various depressive behaviors are influenced by age of exposure. Depressive behaviors are broken down into the following categories: mood and affect, anhedonia, energy, working memory, sleep-wake, appetite changes, suicide, and general malaise. Cross-species evidence from humans, nonhuman primates, rats, and mice within each of these categories is discussed. In conclusion, sensitive periods for affective-related behaviors (anxiety, mood, and controllability) occur earlier in life, while other aspects of depression are associated with adversity later during adolescence.

Very few studies have assessed whether socioeconomic and psychosocial adversity during childhood are associated with objective measures of aging later in life. We assessed associations of socioeconomic position (SEP) and total psychosocial adversity during childhood, with objectively measured cognitive and physical capability in women during midlife. Adverse childhood experiences were retrospectively reported at mean ages 28-30 years in women from the Avon Longitudinal Study of Parents And Children (N = 2,221). We investigated associations of childhood SEP and total psychosocial adversity, with composite measures of cognitive and physical capability at mean age 51 years. There was evidence that, compared with participants whose fathers had professional occupations, participants whose fathers had managerial/technical, skilled nonmanual, skilled manual, and partly or unskilled manual occupations had, on average, lower physical and cognitive capability. There was a clear trend for increasing magnitudes of association with lowering childhood SEP. There was also evidence that greater total psychosocial adversity in childhood was associated with lower physical capability. Total psychosocial adversity in childhood was not associated with cognitive capability. Lower SEP in childhood is detrimental to cognitive and physical capability in midlife, at least in part, independently of subsequent SEP in adulthood. Greater psychosocial adversity in childhood is associated with poorer physical capability, independently of social disadvantage in childhood. Our findings highlight the need for interventions to both identify and support children experiencing socioeconomic or psychosocial of adversity as early as possible.

Breadon, Jonith Y; Barnes, Chad A

2007-01-01

Photoepilation, utilizing lasers and noncoherent light sources, is designed to irradiate as much of the follicular unit as possible, with melanin as the target chromophore. Wavelength absorption should generate energy sufficient to heat and destroy the hair follicle, while preserving the surrounding tissue. When performing photoepilation on African-American skin (Fitzpatrick skin types IV-VI) a greater risk of potential epidermal adverse events, such as dyspigmentation, blistering, crusting, edema, and subsequent scarring, is possible. To reduce epidermal melanin absorption of energy longer wavelengths are considered safer for use on Fitzpatrick skin types IV to VI. This article reviews and compares the reported incidences of adverse events in African-American skin, utilizing lasers and noncoherent light sources for assisted hair removal.

The Protective Effects of Family Support on the Relationship between Official Intervention and General Delinquency across the Life Course.

PubMed

Dong, Beidi; Krohn, Marvin D

2017-03-01

Previous research on the labeling perspective has identified mediational processes and the long-term effects of official intervention in the life course. However, it is not yet clear what factors may moderate the relationship between labeling and subsequent offending. The current study integrates Cullen's (1994) social support theory to examine how family social support conditions the criminogenic, stigmatizing effects of official intervention on delinquency and whether such protective effects vary by developmental stage. Using longitudinal data from the Rochester Youth Development Study, we estimated negative binomial regression models to investigate the relationships between police arrest, family social support, and criminal offending during both adolescence and young adulthood. Police arrest is a significant predictor of self-reported delinquency in both the adolescent and adult models. Expressive family support exhibits main effects in the adolescent models; instrumental family support exhibits main effects at both developmental stages. Additionally, instrumental family support diminishes some of the predicted adverse effects of official intervention in adulthood. Perception of family support can be critical in reducing general delinquency as well as buffering against the adverse effects of official intervention on subsequent offending. Policies and programs that work with families subsequent to a criminal justice intervention should emphasize the importance of providing a supportive environment for those who are labeled.

The 3 fluoroquinolone (FQ) antibiotics - ciprofoxacin, levofoxacin, and moxifoxacin - are commonly administered to oncology patients. Although these oral antibiotics are approved by the US Food and Drug Administration (FDA) for treatment of urinary tract infections, acute bacterial sinusitis, or bacterial infection in patients with chronic obstructive pulmonary disease, they are commonly prescribed off-label to neutropenic cancer patients for the prevention and treatment of infections associated with febrile neutropenia. New serious FQ-associated safety concerns have been identified through novel collaborations between FQ-treated persons who have developed long-term neuropsychiatric (NP) toxicity, pharmacovigilance experts, and basic scientists. To conduct basic science and clinical investigations of a newly identified adverse drug reaction, termed FQ-associated disability. 5 groups of C57BL/6 mice receiving the antibiotic ciprofoxacin in 10-mg increments (10 mg/kg-50 mg/kg) and 1 group of control mice were evaluated. The Southern Network on Adverse Reactions (SONAR) and a social network of FQ-treated persons with long-term NP toxicity (the Floxed Network) conducted a web-based survey. The clinical toxicity manifestations reported by 94 respondents to the web-based survey of persons who had received 1 or more doses of an FQ prescribed for any indication (generally at FDA-approved dosages) and who subsequently experienced possible adverse drug reactions were compared with adverse event information included on the product label for levofoxacin and with FQ-associated adverse events reported to the FDA's MedWatch program. Mice treated with ciprofoxacin had lower grip strengths, reduced balance, and depressive behavior compared with the controls. For the survey, 93 of 94 respondents reported FQ-associated events including anxiety, depression, insomnia, panic attacks, clouded thinking, depersonalization, suicidal thoughts, psychosis, nightmares, and impaired memory beginning within days of FQ initiation or days to months of FQ discontinuation. The FDA Adverse Event Reporting System (FAERS) included 210,705 adverse events and 2,991 fatalities for FQs. Levofoxacin and ciprofoxacin toxicities were neurologic (30% and 26%, respectively), tendon damage (8% and 6%), and psychiatric (10% and 2%). In 2013, an FDA safety review reported that FQs affect mammalian topoisomerase II, especially in mitochondria. In 2013 and 2014, SONAR fled citizen petitions requesting black box revisions identifying neuropsychiatric toxicities and mitochrondrial toxicity as serious levofoxacin-associated adverse drug reactions. In 2015, FDA advisors recommended that FQ product labels be revised to include information about this newly identified disability syndrome termed "FQ-associated disability" (FQAD). Basic science studies evaluated NP toxicity for only 1 FQ, ciprofoxacin. Pharmacovigilance investigators, a social network, and basic scientists can collaborate on pharmacovigilance investigations. Revised product labels describing a new serious adverse drug reaction, levofoxacin-associated long-term disability, as recommended by an FDA advisory committee, are advised. ©2016 Frontline Medical Communications.

OBJECTIVE To characterize adverse reactions to oral administration of a combination of praziquantel and pyrantel embonate or pyrantel pamoate, with or without oxantel embonate, in captive cheetahs (Acinonyx jubatus). DESIGN Retrospective case series and case-control study. ANIMALS 16 captive cheetahs with signs of adverse reaction to oral administration of praziquantel and pyrantel, with or without oxantel embonate (affected group), and 27 cheetahs without such reactions (unaffected group), all from 3 independent facilities. PROCEDURES Medical records and postmortem findings for affected cheetahs were reviewed and compared with those of unaffected animals. Anthelmintic doses administered, age, and sex of cheetahs were compared between groups. RESULTS 3 reactions in affected cheetahs were fatal, whereas the remainder ranged from mild to severe. Postmortem examination failed to reveal any disease processes or conditions to explain the deaths. No differences in anthelmintic dose were identified between affected and unaffected cheetahs for all facilities combined, and no correlation existed between dose and reaction severity. No association with sex was detected, but affected cheetahs were significantly younger than unaffected cheetahs. This difference was not significant after controlling for facility. CONCLUSIONS AND CLINICAL RELEVANCE Cheetahs were concluded to have had an adverse reaction to the praziquantel-pyrantel combination because of temporal proximity of onset of clinical signs to dose administration, similarity of signs to those reported for toxicosis in other species for these drugs, and a lack of other disease process or environmental explanatory factors. A highly cautious approach to the use of this drug combination is recommended for cheetahs.

The adverse health effects of chronic cannabis use.

This paper summarizes the most probable of the adverse health effects of regular cannabis use sustained over years, as indicated by epidemiological studies that have established an association between cannabis use and adverse outcomes; ruled out reverse causation; and controlled for plausible alternative explanations. We have also focused on adverse outcomes for which there is good evidence of biological plausibility. The focus is on those adverse health effects of greatest potential public health significance--those that are most likely to occur and to affect a substantial proportion of regular cannabis users. These most probable adverse effects of regular use include a dependence syndrome, impaired respiratory function, cardiovascular disease, adverse effects on adolescent psychosocial development and mental health, and residual cognitive impairment.

Sickness absence has been shown to be a risk marker for severe future health outcomes, such as disability retirement and premature death. However, it is poorly understood how all-cause and diagnosis-specific sickness absence is reflected in subsequent physical and mental health functioning over time. The aim of this study was to examine the association of all-cause and diagnosis-specific sickness absence with subsequent changes in physical and mental health functioning among ageing municipal employees. Prospective survey and register data from the Finnish Helsinki Health Study and the Social Insurance Institution of Finland were used. Register based records for medically certified all-cause and diagnostic-specific sickness absence spells (>14 consecutive calendar days) in 2004-2007 were examined in relation to subsequent physical and mental health functioning measured by Short-Form 36 questionnaire in 2007 and 2012. In total, 3079 respondents who were continuously employed over the sickness absence follow-up were included in the analyses. Repeated-measures analysis was used to examine the associations. During the 3-year follow-up, 30% of the participants had at least one spell of medically certified sickness absence. All-cause sickness absence was associated with lower subsequent physical and mental health functioning in a stepwise manner: the more absence days, the poorer the subsequent physical and mental health functioning. These differences remained but narrowed slightly during the follow-up. Furthermore, the adverse association for physical health functioning was strongest among those with sickness absence due to diseases of musculoskeletal or respiratory systems, and on mental functioning among those with sickness absence due to mental disorders. Sickness absence showed a persistent adverse stepwise association with subsequent physical and mental health functioning. Evidence on health-related outcomes after long-term sickness absence may provide useful information for targeted interventions to promote health and workability.

Methods We present a case series of three patients who developed bilateral leg edema following initiation of quetiapine. Results One of these patients had a recurrence of edema with subsequent rechallenge. Another patient developed quetiapine-induced edema following a prior episode of olanzapine-induced edema. All the cases present a compelling temporal relationship between the drug challenge and the adverse event. Conclusions Prompt recognition and intervention with discontinuation of the offending agent is important for this potentially serious, seemingly idiosyncratic, vascular complication. PMID:19439156

Abstract Objective To evaluate the association between adverse childhood experiences – e.g. abuse, neglect, domestic violence and parental separation, substance use, mental illness or incarceration – and the health of young adults in eight eastern European countries. Methods Between 2010 and 2013, adverse childhood experience surveys were undertaken in Albania, Latvia, Lithuania, Montenegro, Romania, the Russian Federation, The former Yugoslav Republic of Macedonia and Turkey. There were 10 696 respondents – 59.7% female – aged 18–25 years. Multivariate modelling was used to investigate the relationships between adverse childhood experiences and health-harming behaviours in early adulthood including substance use, physical inactivity and attempted suicide. Findings Over half of the respondents reported at least one adverse childhood experience. Having one adverse childhood experience increased the probability of having other adverse childhood experiences. The number of adverse childhood experiences was positively correlated with subsequent reports of health-harming behaviours. Compared with those who reported no adverse experiences, respondents who reported at least four adverse childhood experiences were at significantly increased risk of many health-harming behaviours, with odds ratios varying from 1.68 (95% confidence interval, CI: 1.32–2.15) – for physical inactivity – to 48.53 (95% CI: 31.98–76.65) – for attempted suicide. Modelling indicated that prevention of adverse childhood experiences would substantially reduce the occurrence of many health-harming behaviours within the study population. Conclusion Our results indicate that individuals who do not develop health-harming behaviours are more likely to have experienced safe, nurturing childhoods. Evidence-based programmes to improve parenting and support child development need large-scale deployment in eastern European. PMID:25378755

The good and bad of being fair: effects of procedural and interpersonal justice behaviors on regulatory resources.

PubMed

Johnson, Russell E; Lanaj, Klodiana; Barnes, Christopher M

2014-07-01

The justice literature has paid considerable attention to the beneficial effects of fair behaviors for recipients of such behaviors. It is possible, however, that exhibiting fair behaviors may come at a cost for actors. In this article, we integrate ego depletion theory with organizational justice research in order to examine the consequences of justice behaviors for actors. We used an experience-sampling method in a sample of managerial employees to examine the relations of performing procedural justice and interpersonal justice behaviors with subsequent changes in actors' regulatory resources. Our results indicate that procedural justice behaviors are draining, whereas interpersonal justice behaviors are replenishing for actors. Depletion, in turn, adversely affected the performance of citizenship behavior, and depletion mediated relations of justice behavior with citizenship. Furthermore, 2 traits that impact self-regulatory skills--extraversion and neuroticism--moderated the replenishing effects of engaging in interpersonal justice behaviors. We conclude by discussing implications and avenues for future research.

Development of powder metallurgy Al alloys for high temperature aircraft structural applications, phase 2

NASA Technical Reports Server (NTRS)

Chellman, D. J.

1982-01-01

In this continuing study, the development of mechanically alloyed heat resistant aluminum alloys for aircraft were studied to develop higher strength targets and higher service temperatures. The use of higher alloy additions to MA Al-Fe-Co alloys, employment of prealloyed starting materials, and higher extrusion temperatures were investigated. While the MA Al-Fe-Co alloys exhibited good retention of strength and ductility properties at elevated temperatures and excellent stability of properties after 1000 hour exposure at elevated temperatures, a sensitivity of this system to low extrusion strain rates adversely affected the level of strength achieved. MA alloys in the Al-Li family showed excellent notched toughness and property stability after long time exposures at elevated temperatures. A loss of Li during processing and the higher extrusion temperature 482 K (900 F) resulted in low mechanical strengths. Subsequent hot and cold working of the MA Al-Li had only a mild influence on properties.

Short-term zidovudine monotherapy (ZDVm) remains an option for some pregnant HIV-positive women not requiring treatment for their own health but may affect treatment responses once antiretroviral therapy (ART) is subsequently started. Data were obtained by linking two UK studies: the UK Collaborative HIV Cohort (UK CHIC) study and the National Study of HIV in Pregnancy and Childhood (NSHPC). Treatment responses were assessed for 2028 women initiating ART at least one year after HIV-diagnosis. Outcomes were compared using logistic regression, proportional hazards regression or linear regression. In adjusted analyses, ART-naïve (n = 1937) and ZDVm-experienced (n = 91) women had similar increases in CD4 count and a similar proportion achieving virological suppression; both groups had a low risk of AIDS. In this setting, antenatal ZDVm exposure did not adversely impact on outcomes once ART was initiated for the woman's health.

We examined self-reported physical health during the first 2 years following the 2004 tsunami in Thailand. We assessed physical health with the revised Short Form Health Survey. We evaluated 6 types of tsunami exposure: personal injury, personal loss of home, personal loss of business, loss of family member, family member's injury, and family's loss of business. We examined the relationship between tsunami exposure and physical health with multivariate linear regression. One year post-tsunami, we interviewed 1931 participants (97.2% response rate), and followed up with 1855 participants 2 years after the tsunami (96.1% follow-up rate). Participants with personal injury or loss of business reported poorer physical health than those unaffected (P < .001), and greater health impacts were found for women and older individuals. Exposure to the tsunami disaster adversely affected physical health, and its impact may last for longer than 1 year, which is the typical time when most public and private relief programs withdraw.

Zinc was readily acquired by all HAP samples in the absence of added calcium, the amount adsorbed being proportional to the HAP surface area; about 9 mumol Zn/m2 was adsorbed at high zinc concentrations. As zinc was acquired, calcium was released, consistent with 1:1 Ca:Zn exchange. Soluble calcium reduced zinc uptake and similarly, calcium post-treatment released zinc. Pretreatment of HAP with 0.5 mM zinc reduced its subsequent ability to undergo seeded crystal growth, as did extracts of a toothpaste containing 0.5% zinc citrate, even in the presence of saliva. The reverse reaction, i.e. displacement of adsorbed zinc by salivary levels of calcium, however, indicates the mechanism by which zinc can reduce calculus formation in vivo by inhibiting plaque mineralisation without adversely affecting the anti-caries effects of fluoride.

The removal of CO2 and tar in fuel gas produced by biomass thermal conversion has aroused more attention due to their adverse effects on the subsequent fuel gas application. High quality fuel gas production from sawdust pyrolysis with CaO was studied in this paper. The results of pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) experiments indicate that the mass ratio of CaO to sawdust (Ca/S) remarkably affects the behavior of sawdust pyrolysis. On the basis of Py-GC/MS results, one system of a moving bed pyrolyzer coupled with a fluid bed combustor has been developed to produce high quality fuel gas. The lower heating value (LHV) of the fuel gas was above 16MJ/Nm(3) and the content of tar was under 50mg/Nm(3), which is suitable for gas turbine application to generate electricity and heat. Therefore, this technology may be a promising route to achieve high quality fuel gas for biomass utilization. Copyright © 2014 Elsevier Ltd. All rights reserved.

Owing to recent climate changes, dust storms are increasingly common, particularly in the Middle East region. Dust accumulation and subsequent mud formation on solid surfaces in humid environments typically have adverse effects on surface properties such as optical transmittance, surface texture, and microhardness. This is usually because the mud, which contains alkaline and ionic species, adheres strongly to the surface, often through chemical bonds, and is therefore difficult to remove. In this study, environmental dust and the after-effects of mud formed on a polycarbonate sheet, which is commonly used as a protective glass in photovoltaic cells. Ionic compounds (OH(-)) are shown to significantly affect the optical, mechanical, and textural characteristics of the polycarbonate surface, and to increase the adhesion work required to remove the dry mud from the polycarbonate surface upon drying. Such ability to modify characteristics of the polycarbonate surface could address the dust/mud-related limitations of superhydrophobic surfaces.

Whether water resource developers are utility operators, cities, industrialists of agriculturalists, their interests and those of affected landowners must accommodate each other. They must come together as men, and compromise their difficulties. Past disputes and their resolutions are guides to present and future flood-hazard settlement. Utah Lake and the Jordan River were once the setting for an equitable settlement of a flood hazard. In 1885, President John Taylor (President Taylor) of the Church of Jesus Christ of Latter-day Saints played a significant role in bringing about a compromise between downstream water users in Salt Lake County, Utah, and adversely affectedmore » upstream landowners in Provo and other parts of Utah County. Subsequent periodic flooding resulted in a second compromise agreement a century later. This paper considers the Utah Lake and Jordan River experiences. It examines the two compromises, how they came about, and their impact upon water resource management. In addition to their historical interest, these settlements provide useful guidance for negotiation and resolution of flood hazard disputes.« less

Male obesity and subfertility, is it really about increased adiposity?

PubMed Central

McPherson, Nicole O; Lane, Michelle

2015-01-01

The prevalence of overweight and obesity in reproductive-aged men is increasing worldwide, with >70% of men >18 years classified as overweight or obese in some western nations. Male obesity is associated with male subfertility, impairing sex hormones, reducing sperm counts, increasing oxidative sperm DNA damage and changing the epigenetic status of sperm. These changes to sperm function as a result of obesity, are further associated with impaired embryo development, reduced live birth rates and increased miscarriage rates in humans. Animal models have suggested that these adverse reproductive effects can be transmitted to the offspring; suggesting that men's health at conception may affect the health of their children. In addition to higher adiposity, male obesity is associated with comorbidities, including metabolic syndrome, hypercholesterolemia, hyperleptinemia and a pro-inflammatory state, all which have independently been linked with male subfertility. Taken together, these findings suggest that the effects of male obesity on fertility are likely multifactorial, with associated comorbidities also influencing sperm, pregnancy and subsequent child health.

Several solutions, ranging from increased technician duties to salary raises, automation, and increasing job satisfaction, have been presented in the literature as methods of assuaging the pharmacist shortage. Although a significant portion of pharmacy graduates from American pharmacy colleges are foreign nationals, no marketing strategies have been elucidated in the retention and recruitment of foreign nationals through labor certification. Labor certifications are generally approved by the Secretary of Labor if the following factors have been verified: 1) there are not sufficient United States workers who are able, willing, qualified, and available for employment; and 2) the employment of the foreign national will not adversely affect the wages and working conditions of U.S. workers similarly employed. When properly understood, the labor certification process is a test of the job market where foreigners, by virtue of their skills and qualifications, attain certification which subsequently leads to permanent residency (green card). The objective of this report is to elucidate the tedious yet effective method of retaining American-educated foreign nationals through labor certification.

Aggregate formation affects ultrasonic disruption of microalgal cells.

Ultrasonication is a cell disruption process of low energy efficiency. This study dosed K(+), Ca(2+) and Al(3+) to Chlorella vulgaris cultured in Bold's Basal Medium at 25°C and measured the degree of cell disruption under ultrasonication. Adding these metal ions yielded less negatively charged surfaces of cells, while with the latter two ions large and compact cell aggregates were formed. The degree of cell disruption followed: control=K(+)>Ca(2+)>Al(3+) samples. Surface charges of cells and microbubbles have minimal effects on the microbubble number in the proximity of the microalgal cells. Conversely, cell aggregates with large size and compact interior resist cell disruption under ultrasonication. Staining tests revealed high diffusional resistance of stains over the aggregate interior. Microbubbles may not be effective generated and collapsed inside the compact aggregates, hence leading to low cell disruption efficiencies. Effective coagulation/flocculation in cell harvesting may lead to adverse effect on subsequent cell disruption efficiency. Copyright © 2015 Elsevier Ltd. All rights reserved.

Pickles are popular in China and exhibits health-promoting effects. However, nitrite produced during fermentation adversely affects health due to formation of methemoglobin and conversion to carcinogenic nitrosamine. Fruiting bodies of the mushroom Boletus edulis were capable of inhibiting nitrite production during pickle fermentation. A 90-kDa nitrite reductase (NiR), demonstrating peptide sequence homology to fungal nitrite reductase, was isolated from B. edulis fruiting bodies. The optimum temperature and pH of the enzyme was 45 °C and 6.8, respectively. B. edulis NiR was capable of prolonging the lifespan of nitrite-intoxicated mice, indicating that it had the action of an antidote. The enzyme could also eliminate nitrite from blood after intragastric administration of sodium nitrite, and after packaging into capsule, this nitrite-eliminating activity could persist for at least 120 minutes thus avoiding immediate gastric degradation. B. edulis NiR represents the first nitrite reductase purified from mushrooms and may facilitate subsequent applications. PMID:26446494

Substance use disorders are credited with greater amounts of death and illness than all other preventable health problems. Billions of dollars are spent on efforts to control drug supplies and fund various treatment approaches, but relatively little resources have been directed towards investigating how environmental conditions can contribute to or detract from substance user's individual motivation to change behavior. Hurricane Katrina caused untold property damage and upheaval, in addition to the vast numbers of people whose lives it drastically affected. This article examines how surviving this ordeal, subsequent evacuation, and eventual resettlement in New Orleans or re-location to a different city (in this case, Houston) impacted individuals' motivation to change their substance use patterns and behaviors. This article's approach is grounded in the values of the social work profession and examines: 1) the role of life events in motivating change of substance using behaviors in the absence of formal treatment interventions; and 2) participant resilience in overcoming the adversities inherent to this disaster.

Sublethal Effects of Fenoxycarb on the Plutella xylostella (Lepidoptera: Plutellidae)

2015-01-01

The effects of fenoxycarb, a Juvenile hormone analogue, at sublethal concentrations were tested on some biological parameters of Plutella xylostella (L.) in two consecutive generations. The calculated LC10, LC25, and LC50 values of the insecticide were 21.58, 43.25, and 93.62 mg/liter on third-instar larvae, respectively. Fenoxycarb significantly reduced pupal weight and oviposition period in parent generation. In addition, the fecundity of treated groups (LC10 = 71.06, LC25 = 40.60 eggs per female) in parents was significantly lower than control (169.40 eggs per female). Although fenoxycarb could not affect gross reproductive rate and death rate, it decreased net reproductive rate, intrinsic rate of increase, finite rate of increase, and birth rate in offspring generation. Also, mean generation time and doubling time of treated insects was significantly longer than control at LC10 level. Therefore, the data from this study suggested that fenoxycarb could adversely cause population decline in the subsequent generation. PMID:26136495

Neurophysiological Influence of Musical Training on Speech Perception

Shahin, Antoine J.

2011-01-01

Does musical training affect our perception of speech? For example, does learning to play a musical instrument modify the neural circuitry for auditory processing in a way that improves one's ability to perceive speech more clearly in noisy environments? If so, can speech perception in individuals with hearing loss (HL), who struggle in noisy situations, benefit from musical training? While music and speech exhibit some specialization in neural processing, there is evidence suggesting that skills acquired through musical training for specific acoustical processes may transfer to, and thereby improve, speech perception. The neurophysiological mechanisms underlying the influence of musical training on speech processing and the extent of this influence remains a rich area to be explored. A prerequisite for such transfer is the facilitation of greater neurophysiological overlap between speech and music processing following musical training. This review first establishes a neurophysiological link between musical training and speech perception, and subsequently provides further hypotheses on the neurophysiological implications of musical training on speech perception in adverse acoustical environments and in individuals with HL.

Rift Valley fever (RVF), a zoonotic vectorborne viral disease, causes loss of life among humans and livestock and an adverse effect on the economy of affected countries. Vaccination is the most effective way to protect livestock; however, during protracted interepidemic periods, farmers discontinue vaccination, which leads to loss of herd immunity and heavy losses of livestock when subsequent outbreaks occur. Retrospective analysis of the 2008–2011 RVF epidemics in South Africa revealed a pattern of continuous and widespread seasonal rainfall causing substantial soil saturation followed by explicit rainfall events that flooded dambos (seasonally flooded depressions), triggering outbreaks of disease. Incorporation of rainfall and soil saturation data into a prediction model for major outbreaks of RVF resulted in the correctly identified risk in nearly 90% of instances at least 1 month before outbreaks occurred; all indications are that irrigation is of major importance in the remaining 10% of outbreaks.

In the past couple of years, there has been an outbreak of synthetic cannabinoid (SC) use in major cities in the United States. Patients can present with various symptoms affecting the central nervous and cardiovascular systems. The effects of endocannabinoid on contractility and Ca(2+) signaling have been shown through both cannabinoid receptors and a direct effect on ion channels. These effects result in abnormalities in ionotropy, chronotropy, and conduction. Here we report on two cases of SC abuse and abnormalities in the cardiovascular system. These cases raise concerns about the adverse effects of SCs and the possibility of QTc prolongation and subsequent complications when using antipsychotic medication in the presence of SC abuse. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Given the rise in SC use and the potential effect on the cardiovascular system, physicians need to be mindful of potential cardiac complications, such as QTc prolongation and torsade de pointe, especially when administering medications that have the potential to cause QTc prolongation.

Increasing drying time adversely affects attachment of tissue proteins and prion-associated amyloid to surgical stainless steel, and reduces the efficacy of commercial cleaning chemistries. This study tested the efficacy of commercial humidity retention bags to reduce biofouling on surgical stainless steel and to improve subsequent cleaning. Surgical stainless steel surfaces were contaminated with ME7-infected brain homogenates and left to dry for 15 to 1,440 min either in air, in dry polythene bags or within humidity retention bags. Residual contamination pre/post cleaning was analysed using Thioflavin T/SYPRO Ruby dual staining and microscope analysis. An increase in biofouling was observed with increased drying time in air or in sealed dry bags. Humidity retention bags kept both protein and prion-associated amyloid minimal across the drying times both pre- and post-cleaning. Therefore, humidity bags demonstrate a cheap, easy to implement solution to improve surgical instrument reprocessing and to potentially reduce associated hospital acquired infections.

Neurotoxicity is a common side effect of chemotherapy treatment, with unclear molecular mechanisms. Clinical studies suggest that the most frequent neurotoxic adverse events affect memory and learning, attention, concentration, processing speeds and executive function. Emerging preclinical research points toward direct cellular toxicity and induction of neuroinflammation as key drivers of neurotoxicity and subsequent cognitive impairment. Emerging data now show detectable levels of some chemotherapeutic agents within the CNS, indicating potential disruption of blood brain barrier integrity or transport mechanisms. Blood brain barrier disruption is a key aspect of many neurocognitive disorders, particularly those characterized by a proinflammatory state. Importantly, many proinflammatory mediators able to modulate the blood brain barrier are generated by tissues and organs that are targets for chemotherapy-associated toxicities. This review therefore aims to explore the hypothesis that peripherally derived inflammatory cytokines disrupt blood brain barrier permeability, thereby increasing direct access of chemotherapeutic agents into the CNS to facilitate neuroinflammation and central neurotoxicity. © 2016 UICC.

The population dynamics of Salmonella enterica var. Typhimurium MAE 110 gfp, Escherichia coli O157:H7 gfp, and Pseudomonas fluorescens 32 gfp were investigated in their introduction to cattle excrements and subsequent entering the soil, plants of cress ( Lepidium sativum L.), and migration through the gastroenteric tract of French snails ( Helix pomatia L.). The survival of these bacteria in the excrements and soil was investigated at cyclically changing (day-night, 25-15 °C) and constant (18 °C) temperatures. The cyclically changing temperature adversely affected the survival of E. coli O157:H7 gfp, and P. fluorescens but did not influence S. enterica var. Typhimurium. All the bacteria and, especially, the analogues of enteropathogens showed high survival in the cattle and snail excrements, soil, and on the plants under the gradual decrease in their population. On the cress plants grown in a mixture of cattle excrements and soil, an increase in the number of the introduced bacteria was observed.

The Food and Drug Administration (FDA) is responsible not only for approving drugs but also for monitoring their safety after they reach the market. The complete adverse event profile of a drug is not known at the time of approval because of the small sample size, short duration, and limited generalizability of pre-approval clinical trials. This report describes the FDA's postmarketing surveillance system, to which many clinicians submit reports of adverse drug events encountered while treating their patients. Despite its limitations, the spontaneous reporting system is an extremely valuable mechanism by which hazards with drugs that were not observed or recognized at the time of approval are identified. Physicians are strongly encouraged to submit reports of adverse outcomes with suspect drugs to the FDA, and their reports make a difference. The FDA is strengthening its postmarketing surveillance with access to new data sources that have the potential to further improve the identification, quantification, and subsequent management of drug risk.

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.

Structured vs. Unstructured: Factors Affecting Adverse Drug Reaction Documentation in an EMR Repository

2011-01-01

Adverse reactions to medications to which the patient was known to be intolerant are common. Electronic decision support can prevent them but only if history of adverse reactions to medications is recorded in structured format. We have conducted a retrospective study of 31,531 patients with adverse reactions to statins documented in the notes, as identified with natural language processing. The software identified statin adverse reactions with sensitivity of 86.5% and precision of 91.9%. Only 9020 of these patients had an adverse reaction to a statin recorded in structured format. In multivariable analysis the strongest predictor of structured documentation was utilization of EMR functionality that integrated the medication list with the structured medication adverse reaction repository (odds ratio 48.6, p < 0.0001). Integration of information flow between EMR modules can help improve documentation and potentially prevent adverse drug events. PMID:22195188

A medical intervention is a medical procedure or application intended to relieve or prevent illness or injury. Examples of medical interventions include vaccination and drug administration. After a medical intervention, adverse events (AEs) may occur which lie outside the intended consequences of the intervention. The representation and analysis of AEs are critical to the improvement of public health. The Ontology of Adverse Events (OAE), previously named Adverse Event Ontology (AEO), is a community-driven ontology developed to standardize and integrate data relating to AEs arising subsequent to medical interventions, as well as to support computer-assisted reasoning. OAE has over 3,000 terms with unique identifiers, including terms imported from existing ontologies and more than 1,800 OAE-specific terms. In OAE, the term 'adverse event' denotes a pathological bodily process in a patient that occurs after a medical intervention. Causal adverse events are defined by OAE as those events that are causal consequences of a medical intervention. OAE represents various adverse events based on patient anatomic regions and clinical outcomes, including symptoms, signs, and abnormal processes. OAE has been used in the analysis of several different sorts of vaccine and drug adverse event data. For example, using the data extracted from the Vaccine Adverse Event Reporting System (VAERS), OAE was used to analyse vaccine adverse events associated with the administrations of different types of influenza vaccines. OAE has also been used to represent and classify the vaccine adverse events cited in package inserts of FDA-licensed human vaccines in the USA. OAE is a biomedical ontology that logically defines and classifies various adverse events occurring after medical interventions. OAE has successfully been applied in several adverse event studies. The OAE ontological framework provides a platform for systematic representation and analysis of adverse events and of the factors (e.g., vaccinee age) important for determining their clinical outcomes.

Living in conditions of chronic adversity renders many women more vulnerable to experiencing gender-based violence (GBV). In addition to GBV's physical and social consequences, the psychological effects can be pervasive. Access to evidence-based psychological interventions that seek to support the mental health of women affected by such adversity is rare in low- and middle-income countries. The current study evaluates a brief evidence-informed psychological intervention developed by the World Health Organization for adults impacted by adversity (Problem Management Plus; PM+). A feasibility randomised control trial (RCT) was conducted to inform a fully powered trial. Community health workers delivered the intervention to 70 women residing in three peri-urban settings in Nairobi, Kenya. Women, among whom 80% were survivors of GBV (N = 56), were randomised to receive five sessions of either PM+ (n = 35) by community health workers or enhanced treatment as usual (ETAU; n = 35). PM+ was not associated with any adverse events. Although the study was not powered to identify effects and accordingly did not identify effects on the primary outcome measure of general psychological distress, women survivors of adversity, including GBV, who received PM+ displayed greater reductions in posttraumatic stress disorder symptoms following treatment than those receiving ETAU. This feasibility study suggests that PM+ delivered by lay health workers is an acceptable and safe intervention to reach women experiencing common mental disorders and be inclusive for those affected by GBV and can be studied in a RCT in this setting. The study sets the stage for a fully powered, definitive controlled trial to assess this potentially effective intervention.

Human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) and poor access to water are two primary global health issues. Poor access to water may significantly affect families infected with HIV and result in adverse social and health consequences. A qualitative study used semi-structured interviews to understand health and social outcomes of families after the implementation of water interventions in rural Kenya. One major sub-theme emerged during this research, which included the effects of water on an HIV-affected family. Prior to the water interventions, common adverse health effects from lack of nutrition, water, and poor hygiene were experienced. After receiving access to water, nutrition and hygiene were improved and additional time was gained and used to reinforce relationships and spread awareness about HIV/AIDS. This study provides need-based evidence for access to safe drinking water in order to decrease adverse health outcomes and improve the quality of life for HIV-affected individuals.

Spontaneous breathing trials (SBTs) are used to assess the readiness for discontinuation of mechanical ventilation. When airway resistance (R aw ) is elevated, the imposed work of breathing can lead to prolongation of mechanical ventilation. Biofilm and mucus build-up within the endotracheal tube (ETT) can increase R aw . Scraping the ETT can remove the biofilm build-up and decrease mechanical R aw . The primary aim of this study was to evaluate the impact of ETT scraping on R aw . The secondary aim was to determine whether decreasing R aw would impact subsequent SBT success. Intubated, mechanically ventilated subjects were enrolled if they failed an SBT and had an R aw of > 10 cm H 2 O/L/s. SBT failure was based on institutional guidelines, and R aw was calculated by subtracting the difference between the measured peak and plateau pressures using a square flow waveform with an inspiratory flow set at 60 L/min. The endOclear device was inserted into the ETT and withdrawn per manufacturer's guidelines. Scraping was repeated until the ETT was cleared. Change in R aw was compared pre- and post-ETT scraping using a paired t test. A Mann-Whitney U test evaluated the difference in percentage change in R aw between SBT groups. Twenty-nine subjects completed the study. The mean pre- and post-ETT scraping R aw values were 15.17 ± 3.83 and 12.05 ± 3.19 cm H 2 O/L/s, respectively ( P < .001). Subsequent SBT success was 48%; however, there was no difference in percentage change in R aw between subsequent passed SBT (18.61% [interquartile range 8.90-33.93%]) and failed SBT (23.88% [interquartile range 0.00-34.80%]), U = 78.5, z = -0.284, P = .78. No adverse events were noted with ETT scraping. This study demonstrated that ETT scraping can reduce R aw . The decrease in R aw post-ETT scraping did not affect subsequent SBT success.

Neural tube defects (NTDs) are associated with substantial mortality, morbidity, disability, and psychological and economic costs. Many are preventable with folic acid, and access to appropriate services for those affected can improve survival and quality of life. We used a compartmental model to estimate global and regional birth prevalence of NTDs (live births, stillbirths, and elective terminations of pregnancy) and subsequent under-5 mortality. Data were identified through web-based reviews of birth defect registry databases and systematic literature reviews. Meta-analyses were undertaken where appropriate. For 2015, our model estimated 260,100 (uncertainty interval (UI): 213,800-322,000) NTD-affected birth outcomes worldwide (prevalence 18.6 (15.3-23.0)/10,000 live births). Approximately 50% of cases were elective terminations of pregnancy for fetal anomalies (UI: 59,300 (47,900-74,500)) or stillbirths (57,800 (UI: 35,000-88,600)). Of NTD-affected live births, 117,900 (∼75%) (UI: 105,500-186,600) resulted in under-5 deaths. Our systematic review showed a paucity of high-quality data in the regions of the world with the highest burden. Despite knowledge about prevention, NTDs remain highly prevalent worldwide. Lack of surveillance and incomplete ascertainment of affected pregnancies make NTDs invisible to policy makers. Improved surveillance of all adverse outcomes is needed to improve the robustness of total NTD prevalence estimation, evaluate effectiveness of prevention through folic acid fortification, and improve outcomes through care and rehabilitation. © 2018 The Authors.

Daniels, K; Guppy, A

1997-04-01

Tests of the influence of affective psychological well-being on stressors, locus of control, and social support in a 1-month follow-up study of 210 male and 34 female British accountants is reported. There was a marginally significant association between the level of psychological symptoms and subsequent reports of intensity of quantitative workload stressors. A significant interaction between psychological symptoms and a measure of depression-enthusiasm was found to predict subsequent locus of control. The results indicate a differential pattern of associations between aspects of affective well-being and subsequent reports of social support. The results also indicate that initially more frequent stressors are associated with subsequently less intense stressors of the same type. The findings highlight the dynamic and reciprocal nature of the occupational stress process.

Hip fractures are one of the most common types of orthopaedic injury with high rates of morbidity. Currently, no study has compared risk factors and adverse events following the different types of hip fracture surgeries. The purpose of this paper is to investigate the major and minor adverse events and risk factors for complication development associated with five common surgeries for the treatment of hip fractures using the NSQIP database. Using the ACS-NSQIP database, complications for five forms of hip surgeries were selected and categorized into major and minor adverse events. Demographics and clinical variables were collected and an unadjusted bivariate logistic regression analyses was performed to determine significant risk factors for adverse events. Five multivariate regressions were run for each surgery as well as a combined regression analysis. A total of 9640 patients undergoing surgery for hip fracture were identified with an adverse events rate of 25.2% (n=2433). Open reduction and internal fixation of a femoral neck fracture had the greatest percentage of all major events (16.6%) and total adverse events (27.4%), whereas partial hip hemiarthroplasty had the greatest percentage of all minor events (11.6%). Mortality was the most common major adverse event (44.9-50.6%). For minor complications, urinary tract infections were the most common minor adverse event (52.7-62.6%). Significant risk factors for development of any adverse event included age, BMI, gender, race, active smoking status, history of COPD, history of CHF, ASA score, dyspnoea, and functional status, with various combinations of these factors significantly affecting complication development for the individual surgeries. Hip fractures are associated with significantly high numbers of adverse events. The type of surgery affects the type of complications developed and also has an effect on what risk factors significantly predict the development of a complication. Concerted efforts from orthopaedists should be made to identify higher risk patients and prevent the most common adverse events that occur postoperatively. Copyright © 2014 Elsevier Ltd.

We investigated whether time of birth, unit volume, and staff seniority affect neonatal outcome in neonates born at ≥34 +0 weeks of gestation. Population-based prospective cohort study. Ten public hospitals in the Austrian province of Styria. A total of 87 065 neonates delivered in the period 2004-2015. Based on short-term outcome data, generalised linear mixed models were used to calculate the risk for adverse and severely adverse neonatal outcomes according to time of birth, unit volume, and staff seniority. Neonatal composite adverse and severely adverse outcome measures. The odds ratio for severely adverse events during the night-time (22:01-07:29 hours) compared with the daytime (07:30-15:00 hours) was 1.35 (95% confidence interval, 95% CI 1.13-1.61). There were no significant differences in neonatal outcome comparing weekdays and weekends, and comparing office hours and shifts. Units with 500-1000 deliveries per year had the lowest risk for adverse events. Adverse and severely adverse neonatal outcomes were least common for midwife-guided deliveries, and became more frequent with the level of experience of the doctors attending the delivery. With increasing pregnancy risks, senior staff attending delivery and delivering in a tertiary centre reduce the odds ratio for adverse events. Different times of delivery were associated with increased adverse neonatal outcomes. The management of uncomplicated deliveries by less experienced staff showed no negative impact on perinatal outcome. In contrast, riskier pregnancies delivered by senior staff in a tertiary centre favour a better outcome. Achieving a better balance in the total number of labour ward staff during the day and the night appears to be a greater priority than increasing the continuous presence of senior obstetrical staff on the labour ward during the out-of-hours period. Deliveries during night time lead to a greater number of neonates experiencing severely adverse events. © 2017 Royal College of Obstetricians and Gynaecologists.

Potential Adverse Effects of Violent Video Gaming: Interpersonal- Affective Traits Are Rather Impaired Than Disinhibition in Young Adults

2018-01-01

The increasing trend of mass shootings, which were associated with excessive use of violent video games, fueled the debate of possible effects violent video games may have on adolescents and young adults. The aim of this study was to investigate the possible link between violent video gaming effects and the disposition of adverse behavior traits such as interpersonal-affective deficits and disinhibition. Data of 167 young adults, collected by an online questionnaire battery, were analyzed for lifetime video game exposure differences (i.e., non-gamers, non-violent video gamers, stopped violent video game users, and ongoing violent video game users) as well as for recent exposure effects on adverse behavior traits (Levenson’s Psychopathy Scale), while controlling for other potentially confounding lifestyle factors. While interpersonal-affective deficits were significantly higher in participants with ongoing violent video game exposure compared to non-gamers and non-violent video gamers, disinhibition was significantly higher in both – stopped and ongoing – violent video game exposure groups compared to non-gamers. Recent violent video game exposure was a stronger predictor for interpersonal-affective deficits, but was also significant for disinhibition. Considering that we observed small to medium effects in a sample of young adults with little to moderate use of violent video games highlights the importance of further investigating the potential adverse effects of violent video games on quality of social relationships.

Childhood adversity has long-lasting neuro-biological effects that can manifest as exaggerated stress responsivity to environmental challenge. These manifestations include a dysregulated hypothalamic-pituitary-adrenocortical (HPA) axis as well as increased levels of inflammatory mediators in response to stress. In this investigation, vagal parasympathetic activity was assessed for its capacity to moderate the relationship between childhood adversity and stress responsivity (cortisol and inflammation) during an acute laboratory challenge (Trier Social Stress Test-TSST). Thirty women recently diagnosed with breast cancer underwent the TSST during which their heart rate was recorded and saliva samples collected for measurement of cortisol and the proinflammatory cytokine, IL-6. Vagal activity during the TSST was calculated as the high-frequency (HF) component of heart rate variability (HRV). Vagal activity during the TSST moderated the effect of childhood adversity on both the cortisol and the IL-6 response. Women who had lower vagal stress-reactivity during the TSST and reported greater childhood adversity showed a larger rise in cortisol and IL-6 when compared to women with lower childhood adversity. The findings demonstrate that women with exposure to childhood adversity and low vagal stress-reactivity (reduced parasympathetic activity) exhibit an elevated stress response characterized by greater cortisol and proinflammatory cytokine release. Inflammatory burden and HPA dysregulation subsequent to stress may impair cancer control.

To determine the impact of earlier urethral interventions on the outcomes of anastomotic urethroplasty in post-traumatic stricture urethra. From October 1995 to March 2008, a total of 58 patients with post-traumatic posterior urethral stricture underwent anastomotic urethroplasty. Eighteen patients had earlier undergone urethral intervention in the form of urethrotomy (3), endoscopic realignment (7), or open urethroplasty (8). Success was defined as no obstructive urinary symptoms, maximum urine flow rate > or = 15 mL/s, normal urethral imaging and/or urethroscopy, and no need of any intervention in the follow-up period. Patients who met the above objective criteria after needing 1 urethrotomy following urethroplasty were defined to have satisfactory outcome and were included in satisfactory result rate along with patients who had a successful outcome. Results were analyzed using unpaired t test, chi-square test, binary logistic regression, Kaplan-Meier curves, and log rank test. Previous interventions in the form of endoscopic realignment or urethroplasty have significant adverse effect on the success rate of subsequent anastomotic urethroplasty for post-traumatic posterior urethral strictures (P <.05). Previous intervention in the form of visual internal urethrotomies (up to 2 times) did not affect the outcome of subsequent anastomotic urethroplasty. Length of stricture and age of patient did not predict the outcome in traumatic posterior urethral strictures in logistic regression analysis. Previous failed railroading or urethroplasty significantly decrease the success of subsequent anastomotic urethroplasty. Hence, a primary realignment or urethroplasty should be avoided in suboptimal conditions and the cases of post-traumatic urethral stricture should be referred to centers with such expertise. 2010 Elsevier Inc.

The life course perspective suggests a pathway may exist among maternal exposure to stressful life events prior to conception (PSLEs), infant birth weight and subsequent offspring health, whereby PSLEs are part of a 'chains-of-risk' that set children on a certain health pathway. No prior study has examined the link between PSLEs and offspring health in a nationally representative sample of US mothers and their children. We used longitudinal, nationally representative data to evaluate the relation between maternal exposure to PSLEs and subsequent measures of infant and toddler health, taking both maternal and obstetric characteristics into account. We examined 6900 mother-child dyads participating in 2 waves of the nationally representative Early Childhood Longitudinal Study-Birth Cohort (n=6900). Infant and toddler health outcomes assessed at 9 and 24 months included overall health status, special healthcare needs and severe health conditions. Adjusted path analyses examined associations between PSLEs, birth weight and child health outcomes. In adjusted analyses, PSLEs increased the risk for very low birth weight (VLBW, <1500 g), which, in turn, predicted poor health at both 9 and 24 months of age. Path analyses demonstrated that PSLEs had small indirect effects on children's subsequent health that operated through VLBW. Our analysis suggests a chains-of-risk model in which women's exposure to PSLEs increases the risk for giving birth to a VLBW infant, which, in turn, adversely affects infant and toddler health. Addressing women's preconception health may have important downstream benefits for their children, although more research is needed to replicate these findings.

The impact of nursing work environments on patient safety outcomes: the mediating role of burnout/engagement.

To test a theoretical model of professional nurse work environments linking conditions for professional nursing practice to burnout and, subsequently, patient safety outcomes. The 2004 Institute of Medicine report raised serious concerns about the impact of hospital restructuring on nursing work environments and patient safety outcomes. Few studies have used a theoretical framework to study the nature of the relationships between nursing work environments and patient safety outcomes. Hospital-based nurses in Canada (N = 8,597) completed measures of worklife (Practice Environment Scale of the Nursing Work Index), burnout (Maslach Burnout Inventory-Human Service Scale), and their report of frequency of adverse patient events. Structural equation modeling analysis supported an extension of Leiter and Laschinger's Nursing Worklife Model. Nursing leadership played a fundamental role in the quality of worklife regarding policy involvement, staffing levels, support for a nursing model of care (vs medical), and nurse/physician relationships. Staffing adequacy directly affected emotional exhaustion, and use of a nursing model of care had a direct effect on nurses' personal accomplishment. Both directly affected patient safety outcomes. The results suggest that patient safety outcomes are related to the quality of the nursing practice work environment and nursing leadership's role in changing the work environment to decrease nurse burnout.

What is the psychological impact of self-weighing? A meta-analysis.

Many people self-weigh and many interventions addressing weight-related problems such as obesity promote self-weighing. However, while self-weighing has been associated with weight loss, there is mixed evidence regarding the psychological impact of this behaviour. The present review aimed to quantify the relationship between self-weighing and: (i) affect (e.g., anxiety, depression); (ii) psychological functioning (e.g., self-esteem); (iii) body-related attitudes and (iv) disordered eating. A computerized search of scientific databases in September 2014 and subsequent ancestry and citation searches identified 29 independent tests of the relationship between self-weighing on psychological outcomes. Meta-analysis was used to quantify the size of the association across the tests. Results indicated that there was no association between self-weighing and affect, body-related attitudes or disordered eating. There was, however, a small-sized negative association between self-weighing and psychological functioning. The age of participants, obesity status, the extent of weight loss, duration of self-weighing and study design (RCT versus correlational) were found to influence at least some of the psychological outcomes of self-weighing. The findings suggest that, for the most part, self-weighing is not associated with adverse psychological outcomes. However, in some cases the association between self-weighing and psychological outcomes may be more negative than in others.

This study examines the interplay between individual and social-developmental factors in the development of positive functioning, substance use problems, and mental health problems. This interplay is nested within positive and negative developmental cascades that span childhood, adolescence, the transition to adulthood, and adulthood. Data are drawn from the Seattle Social Development Project, a gender-balanced, ethnically diverse community sample of 808 participants interviewed 12 times from ages 10 to 33. Path modeling showed short- and long-term cascading effects of positive social environments, family history of depression, and substance using social environments throughout development. Positive family social environments set a template for future partner social environment interaction and had positive influences on proximal individual functioning, both in the next developmental period and long term. Family history of depression adversely affected mental health functioning throughout adulthood. Family substance use began a cascade of substance-specific social environments across development, which was the pathway through which increasing severity of substance use problems flowed. The model also indicated that adolescent, but not adult, individual functioning influenced selection into positive social environments, and significant cross-domain effects were found in which substance using social environments affected subsequent mental health.

We conducted a qualitative study to expand our current understanding of the potential link between psychosocial working conditions and diabetes self-management at work. Thirty employed adults with diabetes mellitus living in Germany (n = 19 with type 1, n = 11 with type 2, 57% female, aged 24-64 years) were recruited. Using a topic guide, we carried out in-depth interviews in face-to-face contact or by telephone. Interviews were transcribed and content-analyzed using MaxQDA. Psychosocial working conditions perceived to detrimentally affect self-management activities included, amongst others, a high workload, poor job control, unhygienic working environments, the requirement to work under high or fluctuating temperature, perceived social norms at the workplace, and the attitude to prioritize work-related demands as opposed to diabetes-related demands. The types of self-management activities considered to be adversely affected related to glucose monitoring, insulin injections, dietary control, the ability to recognize hypoglycemia and health care use. Various types of occupational psychosocial factors may determine diabetes self-management practices at the workplace. Quantitative studies are needed to confirm our observations. Subsequently, interventions could be developed and evaluated to improve opportunities to adequately engage into diabetes self-management at work. Copyright © 2018 Elsevier B.V. All rights reserved.

2008-01-01

The objective of this study was to describe seven cases of unilateral bacterial infective coxarthritis from a total of 19 cases of bacterial infective arthritis (BIA), presenting over a two year period. We recorded the history, clinical signs, diagnostic process, treatment and clinical outcome in these cases. The data were obtained from medical records, review of the radiographs, and telephone follow-up with the owners. All of the dogs in this study had severe chronic osteoarthritis secondary to hip dysplasia, which caused periodic hind limb lameness. They were all admitted with severe acute hind-limb lameness. Pelvic radiographs were performed under general anaesthesia shortly after presentation, followed immediately by arthrocentesis of the affected joint. The synovial fluid was evaluated microscopically by direct smear and a sample was sent for culture and sensitivity. An attempt was not made to drain or lavage the affected joint during the course of treatment. The initial choice of antibiotics was empiric and subsequently modified, as required, based on the sensitivity results. Four of the dogs showed a rapid return to weight-bearing after the initiation of antibiotic treatment, and all of the patients returned to their pre-BIA level of function. Neither recurrent infections nor any adverse sequela requiring further intervention were reported by the owners on telephone follow-up.

Mild anemia during pregnancy upregulates placental vascularity development.

Stangret, A; Skoda, M; Wnuk, A; Pyzlak, M; Szukiewicz, D

2017-05-01

The connection between maternal hematological status and pregnancy outcome has been shown by many independent researchers. Attention was initially focused on the adverse effects of moderate and severe anemia. Interestingly, some studies revealed that mild anemia was associated with optimal fetal development and was not affecting pregnancy outcome. The explanation for this phenomenon became a target for scientists. Hemodilution, physiologic anemia and relative decrease in hemoglobin concentration are the changes observed during pregnancy but they do not explain the reasons for the positive influence of mild anemia on a fetomaternal unit. It is hypothesized that hemodilution facilitates placental perfusion because blood viscosity is reduced. Subsequently, it may lead to a decline in hemoglobin concentration. Anemia from its definition implies decreased oxygen carrying capacity of the blood and can result in hypoxemia and even hypoxia, which is a common factor inducing new blood vessels formation. Therefore, we raised the hypothesis that the lowered hemoglobin concentration during pregnancy may upregulate vascular growth factor receptors expression such as VEGFR-1 (Flt-1) and VEGFR-2 (FLK-1/KDR). Consecutively, increased fetoplacental vasculogenesis and angiogenesis provide further expansion of vascular network development, better placental perfusion and hence neither fetus nor the mother are affected.

Chronic histiocytic intervillositis (CHI) of the placenta although rare, has a high recurrence rate, is associated with serious adverse pregnancy outcomes and has no available treatment. This study aims to determine clinical, biochemical and radiological factors associated with CHI, to guide management of subsequent pregnancies. This retrospective observational study included consecutive cases with a histopathologic diagnosis of CHI after 18 weeks of gestation, between 2001 and 2014, and no controls. Clinical (maternal, fetal and delivery outcomes), biochemical (first- and second-trimester biomarkers for fetal aneuploidy and serum alkaline phosphatase) and radiological (second- and third-trimester fetal, placental and Doppler ultrasound) factors associated with a histopathological diagnosis of CHI were identified and results presented as percentages. Outcomes of subsequent pregnancies were described. Of 231 identified cases of 'intervillositis', 33 were confirmed to have CHI, of which only 4/33 (12.1%) had prior uncomplicated term deliveries. During pregnancy, 10/18 (55.5%) had abnormal first-trimester screening, 4/16 (25%) had abnormal second-trimester screening, 6/19 (31.6%) had at least one elevated alkaline phosphatase level, and 15/20 (75%) had at least one abnormal feature on mid-trimester placental ultrasound. In subsequent pregnancies that were closely followed with a combination of biochemical and radiologic tests, there were no cases of fetal loss, and lower incidence of fetal growth restriction and preterm birth. No clinical, biochemical or radiological finding is consistently associated with CHI and adverse outcomes thereof. Whether the incorporation of these tests in individualized care-plans could improve outcomes in subsequent pregnancies needs to be studied further. Copyright © 2018 Elsevier Ltd.

Abstract Objective To examine whether adverse perinatal experiences of children are associated with obsessive compulsive disorder (OCD) in youth. Methods Subjects were 130 children and adolescents with OCD recruited from a family genetic study of pediatric OCD and 49 matched controls from a contemporaneous family case-control study of attention-deficit/hyperactivity disorder (ADHD). Subjects were comprehensively assessed in multiple domains of function. A systematic history of pregnancy, delivery, and infancy complications was obtained. Results Compared to normal controls, children with OCD had mothers with significantly higher rates of illness during pregnancy requiring medical care (χ2 = 8.61, p = 0.003) and more birth difficulties (induced labor, forceps delivery, nuchal cord, or prolonged labor) (χ2 = 7.51, p = 0.006). Among the OCD-affected children, we found several significant associations between adverse perinatal experiences and earlier age at onset, increased OCD severity, and increased risk for comorbid ADHD, chronic tic disorder, anxiety disorder, and major depressive disorder. Conclusion Although exploratory, our analyses found that children with OCD had higher rates of several adverse perinatal experiences compared with controls. Among OCD-affected children, comorbid psychopathology was predicted by specific perinatal risk factors. Prospective studies of perinatal adverse events that minimize potential recall bias and type I errors are needed. PMID:18759647

Can aircraft noise less than or equal 115 to dBA adversely affect reproductive outcome in USAF women?

NASA Astrophysics Data System (ADS)

Brubaker, P. A.

1985-06-01

It has been suggested, mainly through animal studies, that exposure to high noise levels may be associated with lower birth weight, reduced gestational length and other adverse reproductive outcomes. Few studies have been done on humans to show this association. The Air Force employs pregnant women in areas where there is a high potential for exposure to high noise levels. This study proposes a method to determine if there is an association between high frequency noise levels or = 115 dBA and adverse reproductive outcomes through a review of records and self-administered questionnaires in a case-comparison design. Prevelance rates will be calculated and a multiple logistic regression analysis computed for the independent variables that can affect reproduction.

Use of ClinicalTrials.gov to estimate condition-specific nocebo effects and other factors affecting outcomes of analgesic trials.

ClinicalTrials.gov is a registry and results database of federally and privately supported clinical trials conducted worldwide. We sought to answer: what are the characteristics of pain trials; how frequently are these trials stopped and why; what is the magnitude of attrition due to lack of efficacy or adverse events; and whether the withdrawal rates depend on pain syndrome. To facilitate this and subsequent studies, we have developed a system called Sherlock that automatically downloads data from ClinicalTrials.gov into a relational database. We included pain interventional trials. To evaluate attrition, we restricted consideration to prospective randomized, parallel, double-blind, placebo-controlled trials. Of the 82,867 trials, 6% reported results and 5.6% terminated before the planned number of subjects was accrued. Of these early terminations, 38% were due to enrollment difficulties. In the placebo arms, 3.8% of participants withdrew due to lack of efficacy and 4.9% due to adverse events, with proportions differing among pain conditions. Compared with migraine trials, in fibromyalgia trials 5.1% more participants withdrew due to lack of efficacy (95% confidence interval [CI], 2.5-7.8%), and 6.4% more withdrew due to adverse events (95% CI, 4.3-8.6%). Nonsteroidal anti-inflammatory drugs were the treatment class with the lowest adverse events withdrawals. Recruitment challenges account for the largest proportion of noncompleted trials. Attrition rates differ across pain conditions. Migraine studies had the lowest withdrawal rate. Tools like Sherlock facilitate conducting research in the ClinicalTrials.gov registry. ClinicalTrials.gov registry enables researchers to get a snapshot of a specific field and observe changes over time in trial design, including numbers of subjects accrued, and it can inform clinical trial design. We learned that recruitment challenges account for the largest proportion of noncompleted trials, attrition rates differed across pain conditions, and migraine studies had the lowest withdrawal rate.

Stakeholder analysis allows analysts to identify how parties might be affected by government projects. This process involves identifying the likely impacts of a proposed action and stakeholder groups affected by that action. Additionally, the process involves assessing how these groups might be affected and suggesting measures to mitigate any adverse effects. Evidence suggests that the efficiency and effectiveness of government actions can be increased and adverse social impacts mitigated when officials understand how a proposed action might affect stakeholders. This report discusses how to conduct useful stakeholder analyses for government officials making decisions on energy-efficiency and renewable-energy technologies and theirmore » commercialization. It discusses methodological issues that may affect the validity and reliability of findings, including sampling, generalizability, validity, ``uncooperative`` stakeholder groups, using social indicators, and the effect of government regulations. The Appendix contains resource directories and a list of specialists in stakeholder analysis and involvement.« less

Examining acute bi-directional relationships between affect, physical feeling states, and physical activity in free-living situations using electronic ecological momentary assessment.

2017-06-01

Current knowledge about the relationship of physical activity with acute affective and physical feeling states is informed largely by lab-based studies, which have limited generalizability to the natural ecology. This study used ecological momentary assessment to assess subjective affective and physical feeling states in free-living settings across 4 days from 110 non-physically active adults (Age M = 40.4, SD = 9.7). Light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) were measured objectively by an accelerometer. Multilevel modeling was used to test the bi-directional associations between affective and physical feeling states and LPA/MVPA minutes. Higher positive affect, lower negative affect and fatigue were associated with more MVPA over the subsequent 15 min, while higher negative affect and energy were associated with more LPA over the subsequent 15 and 30 min. Additionally, more LPA and MVPA were associated with feeling more energetic over the subsequent 15 and 30 min, and more LPA was additionally associated with feeling more negative and less tired over the subsequent 15 and 30 min. Positive and negative affective states might serve as antecedents to but not consequences of MVPA in adults' daily lives. Changes in LPA may be predicted and followed by negative affective states. Physical feeling states appear to lead up to and follow changes in both LPA and MVPA.

Insulin pumps (for continuous subcutaneous insulin infusion [CSII]) are used widely in type 1 diabetes mellitus. Although there has been considerable study of outcomes, there are few recent data on CSII-associated adverse events and no data on family perceptions of adverse events and their confidence in dealing with them. We approached all families of children and adolescents ≤ 19 years of age on CSII attending the diabetes clinic over a 16-week clinic cycle. Participants completed a retrospective questionnaire examining issues over the previous 12 months. Data on pump adverse events as well as answers to questions pertaining to education and confidence were collected. Our survey received a response rate of 99%, with 235 of the 238 families approached participating. In the preceding 12 months, 104 of 230 (45%) had reported at least one pump-related adverse event (either mechanical or set-related), with an associated 52 of 229 (23%) resulting in pump replacement. This equated to a minimum incidence density of 53 adverse events/100 person-years. Additionally, 18 of 230 (8%) reported a hospital admission or emergency department attendance as a consequence. Pump malfunction and infusion set/site failures were the most common events reported, with one or more events in 58 of 104 (56%) and 47 of 104 (45%), respectively. Adverse events, excluding set/site failures, were associated with older age (13.1 ± 3.4 years vs. 11.9 ± 4 years; P = 0.02). This is the first study to look at family perceptions of adverse events while using modern CSII. It highlights a high self-reported rate of CSII-related adverse events, pump replacement, and subsequent presentation to the hospital. Potential areas for additional targeted education are identified. Further prospective study examining pump adverse event characteristics and incidence is warranted.

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.

The need for a comprehensive medication safety module in medical education.

PubMed

Chandy, Sujith John

2016-10-01

A rising number of medicines and minimal emphasis on rational prescribing in the medical curriculum may compromise medication safety. There is no focused module in the curriculum dealing with factors affecting safety such as quality, medicines management, rational use, and approach to adverse effects. Creating awareness of these issues would hopefully plant a seed of safe prescribing and encourage pharmacovigilance. A study was therefore done to determine the need for such a module. A quasi-experimental pre-post module study. Medical students ( n = 88) completing pharmacology term were recruited after informed consent. A questionnaire containing 20 questions on various themes was administered and scored. Subsequently a module was developed and relevant safety themes taught to the students. After one month, the questionnaire was re-administered. The pre module score was 9.52/20. Knowledge about the various themes, adverse effects, medication management, quality issues and rational use were similar though poor knowledge was evident in specific areas such as clinical trials, look alike-sound alike medicines (LASA) and medicine storage. The post module score was 12.24/20. The improvement of score was statistically significant suggesting the effectiveness of the module. The relatively poor knowledge and improvement with a specific educational module emphasizes the need of such a module within the medical curriculum to encourage safe use of medicines by Indian Medical Graduates (IMG). It is hoped that the policy makers in medical education will introduce such a module within the medical curriculum.

We examined whether radiotransmitters adversely affected the reproductive performance of Cassin's auklets (Ptychoramphus aleuticus) breeding on the California Channel Islands during 1999-2001. We attached external radiotransmitters to 1 partner in 108 Cassin's auklet pairs after nest initiation and used 131 unmarked, but handled, pairs as controls. Compared to alpha chicks raised by radiomarked pairs, alpha chicks raised by unmarked pairs had faster mass growth rates (1.95 ± 0.30 g d−1 vs. 3.37 ± 0.53 g d−1, respectively), faster wing growth rates (2.46 ± 0.10 mm d−1 vs. 2.85 ± 0.05 mm d−1), greater peak fledging masses (118.9 ± 3.5 g vs. 148.3 ± 2.4 g), and higher fledging success (61% vs. 90%). Fledging success was reduced more when we radiomarked the male (50% fledged) rather than the female partner (77% fledged). After fledging an alpha chick, unmarked pairs were more likely to initiate a second clutch (radiomarked: 7%; unmarked: 39%) but did not hatch a second egg (radiomarked: 4%; unmarked: 25%) or fledge a second (beta) chick (radiomarked: 4%; unmarked: 18%) significantly more often than radiomarked pairs. We resighted 12 radiomarked individuals nesting during a subsequent breeding season; each bird had shed its transmitter and healed the site of attachment. We suggest caution in using telemetry to evaluate the reproductive performance of alcids, but marking only females may minimize adverse effects.

A neurobiological perspective on attachment problems in sexual offenders and the role of selective serotonin re-uptake inhibitors in the treatment of such problems.

PubMed

Beech, Anthony R; Mitchell, Ian J

2005-02-01

This paper describes what is currently known about attachment from the development, social-cognitive and biological literatures and outlines the impact on organisms given adverse development experiences that can have an effect upon attachment formation in childhood across these three literatures. We then describe the effects that 'insecure' attachment styles arising in childhood can affect brain chemistry and brain function and subsequently adult social/romantic relationships. In the paper, we note that a number of sexual offenders report adverse childhood experiences and that they possess attachment styles that, taken together, make it likely that they will either seek out intimate attachments in ways where they will have sex with children, perhaps confusing sex with intimacy or in aggressive ways as particularly happens with men who sexually assault adult women. The last section of the paper describes chemical treatment for sexual offenders, focusing on the use of selective serotonin re-uptake inhibitors (SSRIs). We note evidence for the role of SSRIs in promoting more social/affiliative behaviors and speculate on the effects that SSRIs have in the treatment of sexual offenders by targeting areas of the social brain. Here, we would argue that it would be useful to carry out treatment where there is a combination of SSRI treatment (to promote more prosocial feelings and behaviors) in conjunction with therapy that typically addresses thoughts and behaviors, i.e., cognitive-behavioral therapy/schema-focused therapy.

Interim report: review of evidence of the health impact of famine in Ethiopia.

PubMed

Taye, A; Mariam, D Haile; Murray, V

2010-09-01

Historical accounts of famines in Ethiopia go as far back as the 9th century, however, evidence on its impact on health only started to emerge from the 15th century onwards. Unfortunately, famine has been endemic in Ethiopia in the last few decades. The 1973 famine is reported to have claimed over 300,000 lives. In 1985 approximately 10 million people were reported to be starving, with approximately 300,000 already dead and about 1000 dying daily. In the following years, droughts leading to food shortage have had local and national adverse health effects, in particular in 1999/2000. This paper describes the initial findings of a literature review of evidence on the health impact of droughts leading to famine in Ethiopia and highlights gaps in knowledge. The key finding, thus far, is the marked paucity of health impact data. This review also highlights the fact that adverse health impacts of famines are probably complex and long lasting. Interpretation of any health impact data is difficult as there are few baseline data to compare. Health effects also impact livelihoods. Livelihood disruption following famine does not just affect one generation but also subsequent generations. Surveillance systems are needed so that records of the health impacts of a drought that leads to famine can inform action. With climate change bringing increased likelihood of drought and famine in some parts of the world, the findings of this review could be beneficial not just for Ethiopia but also elsewhere.

Environmental impact assessment of mountain tourism in developing regions: A study in Ladakh, Indian Himalaya

Mountain tourism in developing countries is becoming a growing environmental concern due to extreme seasonality, lack of suitable infrastructures and planning, and interference with fragile ecosystems and protected areas. This paper presents a study devoted to assess the adverse environmental impacts of tourism, and in particular of trekking-related activities, in Ladakh, Indian Himalaya. The proposed approach is based on the use of Geographical Information System (GIS) modeling and remote sensing imageries to cope with the lack of data that affect the region. First, stressors associated with trekking, and environmental receptors potentially affected were identified. Subsequently, a baseline study on stressorsmore » (trail use, waste dumping, camping, pack animal grazing and off-road driving) and receptors (soil, water, wildlife, vegetation) was conducted through field work, data collection, and data processing supported by GIS. Finally, impacts were modeled by considering the intensity of the stressors, and the vulnerability and the value of the receptors. The results were spatially aggregated into watershed units, and combined to generate composite impact maps. The study concluded that the most affected watersheds are located in the central and southeastern part of Ladakh, along some of the most visited trails and within the Hemis and the Tsokar Tsomoriri National parks. The main objective of the study was to understand patterns of tourism-induced environmental degradation, so as to support mitigation interventions, as well as the development of suitable tourism policies.« less

Differences in reproductive toxicology between alopecia drugs: an analysis on adverse events among female and male cases

PubMed Central

Li, Qingfeng

2016-01-01

Alopecia is a dermatological condition with limited therapeutic options. Only two drugs, finasteride and minoxidil, are approved by FDA for alopecia treatment. However, little is known about the differences in adverse effects between these two drugs. We examined the clinical reports submitted to the FDA Adverse Event Reporting System (FAERS) from 2004 to 2014. For both female and males, finasteride was found to be more associated with reproductive toxicity as compared to minoxidil. Among male alopecia cases, finasteride was significantly more concurrent with several forms of sexual dysfunction. Among female alopecia cases, finasteride was significantly more concurrent with harm to fetus and disorder of uterus. In addition, drug-gene network analysis indicated that finasteride could profoundly disturb pathways related to sex hormone signaling and oocyte maturation. These findings could provide clues for subsequent toxicological research. Taken together, this analysis suggested that finasteride could be more liable to various reproductive adverse effects. Some of these adverse effects have yet to be warned in FDA-approved drug label. This information can help improve the treatment regimen of alopecia and post-marketing regulation of drug products.

2016-01-01

Early adverse experiences are well understood to affect development and well-being, placing individuals at risk for negative physical and mental health outcomes. A growing literature documents the effects of adversity on developing neurobiological systems. Fewer studies have examined stress neurobiology to understand how to mitigate the effects of early adversity. This review summarizes the research on three neurobiological systems relevant to interventions for populations experiencing high levels of early adversity: the hypothalamic-adrenal-pituitary axis, the prefrontal cortex regions involved in executive functioning, and the system involved in threat detection and response, particularly the amygdala. Also discussed is the emerging field of epigenetics and related interventions to mitigate early adversity. Further emphasized is the need for intervention research to integrate knowledge about the neurobiological effects of prenatal stressors (e.g., drug use, alcohol exposure) and early adversity. The review concludes with a discussion of the implications of this research topic for clinical psychology practice and public policy.

The Protective Effects of Family Support on the Relationship between Official Intervention and General Delinquency across the Life Course

Dong, Beidi; Krohn, Marvin D.

2016-01-01

Purpose Previous research on the labeling perspective has identified mediational processes and the long-term effects of official intervention in the life course. However, it is not yet clear what factors may moderate the relationship between labeling and subsequent offending. The current study integrates Cullen’s (1994) social support theory to examine how family social support conditions the criminogenic, stigmatizing effects of official intervention on delinquency and whether such protective effects vary by developmental stage. Methods Using longitudinal data from the Rochester Youth Development Study, we estimated negative binomial regression models to investigate the relationships between police arrest, family social support, and criminal offending during both adolescence and young adulthood. Results Police arrest is a significant predictor of self-reported delinquency in both the adolescent and adult models. Expressive family support exhibits main effects in the adolescent models; instrumental family support exhibits main effects at both developmental stages. Additionally, instrumental family support diminishes some of the predicted adverse effects of official intervention in adulthood. Conclusions Perception of family support can be critical in reducing general delinquency as well as buffering against the adverse effects of official intervention on subsequent offending. Policies and programs that work with families subsequent to a criminal justice intervention should emphasize the importance of providing a supportive environment for those who are labeled.

The system of countermeasures for the adverse effects of microgravity developed in the USSR supported the successful implementation of long-duration spaceflight (LDS) programs on the Salyut and Mir orbital stations and was subsequently adapted for flights on the International Space Station (ISS). From 2000 through 2010, crews completed 26 ISS flight increments ranging in duration from 140 to 216 d, with the participation of 27 Russian cosmonauts. These flights have made it possible to more precisely determine a crew-member's level of conditioning, better assess the advantages and disadvantages of training processes, and determine prospects for future developments.

2009-08-01

The NHS Redress Act 2006 (UK) is an example of a legislated compensation scheme for adverse health care incidents that aims to supplement the tort-based system of compensation, without going all the way to adopting a no-fault compensation system. It proposes an administrative method of providing speedier and more efficient and responsive remedies to adverse health care incidents than traditional legal proceedings. This article examines the detail of the United Kingdom policy arguments both prior to and since the passage of the legislation, as well as providing a detailed analysis of the original Bill, the parliamentary debates and the subsequent Act.

Divergence Palsy due to Divalproex and Oxcarbazepine.

PubMed

Bouffard, Marc Albert; Caplan, Louis R; Torun, Nurhan

This case series is the first to describe divergence palsy as an adverse effect of antiepileptic drug use. Diplopia is a common adverse effect of antiepileptic drugs, but no explanatory motility deficit has ever been reported. We present 2 patients, 1 on oxcarbazepine and 1 on divalproex, each with a normal examination result between spells and divergency palsy when symptomatic. Discontinuation of the antiepileptic medication led to resolution of the episodes in both cases. Rechallenge with the offending agent after washout in one patient resulted in recurrence of diplopia and divergence palsy, both resolving after subsequent withdrawal of the antiepileptic. Antiepileptic drugs may cause divergence palsy.

Adverse childhood experiences, including abuse, neglect and household instability, affect lifelong health and economic potential. The present study investigates how adverse childhood experiences are associated with food insecurity by exploring caregivers' perceptions of the impact of their childhood adversity on educational attainment, employment and mental health. Semi-structured audio-recorded in-person interviews that included (i) quantitative measures of maternal and child health, adverse childhood experiences (range: 0-10) and food security using the US Household Food Security Survey Module; and (ii) qualitative audio-recorded investigations of experiences with abuse, neglect, violence and hunger over participants' lifetimes. Households in Philadelphia, PA, USA. Thirty-one mothers of children <4 years old who reported low or very low household food security. Twenty-one caregivers (68 %) reported four or more adverse childhood experiences, and this severity was significantly associated with reports of very low food security (Fisher's exact P=0·021). Mothers reporting emotional and physical abuse were more likely to report very low food security (Fisher's exact P=0·032). Qualitatively, participants described the impact of childhood adverse experiences with emotional and physical abuse/neglect, and household substance abuse, on their emotional health, school performance and ability to maintain employment. In turn, these experiences negatively affected their ability to protect their children from food insecurity. The associations between mothers' adverse experiences in childhood and reports of current household food security should inspire researchers, advocates and policy makers to comprehensively address family hardship through greater attention to the emotional health of caregivers. Programmes meant to address nutritional deprivation and financial hardship should include trauma-informed approaches that integrate behavioural interventions.

The immediate and short-term consequences of adult HIV for affected children are well documented. Little research has examined the long-term implications of childhood adversity stemming from caregiver HIV infection. Through overviews provided by experts in the field, together with an iterative process of consultation and refinement, we have extracted insights from the broader field of child development of relevance to predicting the long-term consequences to children affected by HIV and AIDS. We focus on what is known about the impact of adversities similar to those experienced by HIV-affected children, and for which there is longitudinal evidence. Cautioning that findings are not directly transferable across children or contexts, we examine findings from the study of parental death, divorce, poor parental mental health, institutionalization, undernutrition, and exposure to violence. Regardless of the type of adversity, the majority of children manifest resilience and do not experience any long-term negative consequences. However, a significant minority do and these children experience not one, but multiple problems, which frequently endure over time in the absence of support and opportunities for recovery. As a result, they are highly likely to suffer numerous and enduring impacts. These insights suggest a new strategic approach to interventions for children affected by HIV and AIDS, one that effectively combines a universal lattice of protection with intensive intervention targeted to selected children and families.

Aim Response to stress can vary greatly between individuals. However, it remains unknown whether perceived impact of stress on health is associated with adverse health outcomes. We examined whether individuals who report that stress adversely affects their health are at increased risk of coronary heart disease (CHD) compared with those who report that stress has no adverse health impact. Methods and results Analyses are based on 7268 men and women (mean age: 49.5 years, interquartile range: 11 years) from the British Whitehall II cohort study. Over 18 years of follow-up, there were 352 coronary deaths or first non-fatal myocardial infarction (MI) events. After adjustment for sociodemographic characteristics, participants who reported at baseline that stress has affected their health ‘a lot or extremely’ had a 2.12 times higher (95% CI 1.52–2.98) risk of coronary death or incident non-fatal MI when compared with those who reported no effect of stress on their health. This association was attenuated but remained statistically significant after adjustment for biological, behavioural, and other psychological risk factors including perceived stress levels, and measures of social support; fully adjusted hazard ratio: 1.49 (95% CI 1.01–2.22). Conclusions In this prospective cohort study, the perception that stress affects health, different from perceived stress levels, was associated with an increased risk of coronary heart disease. Randomized controlled trials are needed to determine whether disease risk can be reduced by increasing clinical attention to those who complain that stress greatly affects their health.

This study examined the impact of early lifetime adversity (ELA) on affect regulation and personality in persons with family history (FH+) and without (FH-) a family history of alcoholism. We examined the impact of early life adversity in healthy young adults, 18-30 years of age enrolled in a long-term study on risk for alcohol and other substance abuse. ELA was assessed by a composite score of low socioeconomic status and personal experience of physical or sexual abuse and/or separation from parents before age 16, resulting in a score of 0, 1-2, or >3 adverse events. Unstable affect regulation and personality variables were obtained via self-report measures. Higher ELA scores were seen in FH+ (χ(2)=109.2, p<0.0001) and in women (χ(2)=17.82, p=0.0019). Although higher ELA predicted less emotional stability and more behavioral undercontrol, further analysis including both FH and ELA showed that FH+ persons are prone to poor affect regulation, negative moods, and have risky drinking and drug abuse tendencies independent of ELA level. ELA predicts reduced stress reactivity and poorer cognitive control over impulsive behaviors as shown elsewhere. The present work shows that FH+ have poor mood regulation and antisocial characteristics. The greater prevalence of ELA in FH+ persons indicates that life experience and FH+ work in tandem to result in risky patterns of alcohol and drug experimentation to elevate risk for alcoholism. Further studies of genetic and environmental contributions to alcoholism are called for. Published by Elsevier Ireland Ltd.

Optimising mechanical properties of hot forged nickel superalloy 625 components

Hot forging and subsequent heat treatment were resulting in substandard mechanical properties of nickel superalloy, Alloy 625, components. The low strength was found to be due to inadequate deformation during forging, excessive grain growth and precipitation of carbides during subsequent heat treatment. Experimentation in a drop forging company and heat treatment facility led to the establishment of optimal parameters to minimise grain size and mitigate the adverse effects of carbide precipitation, leading to successful fulfilment of mechanical property specifications. This was achieved by reducing the number of operations, maximising the extent of deformation by changing the slug dimensions and its orientation in the die, and minimising the time of exposure to elevated temperatures in both the forging and subsequent heat treatment processes to avoid grain growth.

Stressful life experiences in adolescence and cardiometabolic risk factors in young adulthood.

2015-04-01

An increasing number of studies have provided evidence for the persistent influence of childhood/adolescent socioeconomic adversities on subsequent health outcomes. However, less is known about the distinct and additive influences of these early socioeconomic adversities and adolescents' own stressful life experiences on health outcomes in young adulthood. We used data from 11,030 adolescents who participated in the National Longitudinal Study of Adolescent Health at Waves 1, 3, and 4 and provided biomarker data at Wave 4. Three early socioeconomic adversities (community socioeconomic adversity, family economic hardship, and low parental education) were evaluated. Adolescents' stressful transition to young adulthood was captured by six specific precocious life events as follows: early sex, early marriage or cohabitation, early leaving home, early pregnancy, early employment, and truncated education. A summary measure of cardiovascular and metabolic disease risk was assessed using nine biomarkers. Univariate, bivariate, and multivariate regression analyses were employed. Early socioeconomic adversities and stressful life transition events were uniquely associated with elevated levels of cardiometabolic (CM) biomarkers and cumulative CM disease risk. For all of the biomarkers, young adults in high-adversity/stress groups were more likely to be in the high CM disease risk groups (>75th percentile) than in the low-adversity/stress groups. These findings provide support for the influence of multiple early socioeconomic adversities and adolescents' stressful life transitions on their CM disease risk as young adults. Increased efforts to prevent and mitigate these experiences may improve disease risks across a number of biomarkers. Copyright © 2015 Society for Adolescent Health and Medicine.

Antidepressant-Induced Female Sexual Dysfunction.

PubMed

Lorenz, Tierney; Rullo, Jordan; Faubion, Stephanie

2016-09-01

Because 1 in 6 women in the United States takes antidepressants and a substantial proportion of patients report some disturbance of sexual function while taking these medications, it is a near certainty that the practicing clinician will need to know how to assess and manage antidepressant-related female sexual dysfunction. Adverse sexual effects can be complex because there are several potentially overlapping etiologies, including sexual dysfunction associated with the underlying mood disorder. As such, careful assessment of sexual function at the premedication visit followed by monitoring at subsequent visits is critical. Treatment of adverse sexual effects can be pharmacological (dose reduction, drug discontinuation or switching, augmentation, or using medications with lower adverse effect profiles), behavioral (exercising before sexual activity, scheduling sexual activity, vibratory stimulation, psychotherapy), complementary and integrative (acupuncture, nutraceuticals), or some combination of these modalities.

The study objective was to examine childhood adversity in association with intra-individual changes and inter-individual differences in subclinical psychosis in a representative community cohort over a 30-year period of observation. We analyzed two psychosis syndromes derived from the SCL-90-R - schizotypal signs and schizophrenia nuclear symptoms - in 335 participants. Participants were repeatedly assessed between 1978 (around age 20) and 2008 (around age 50). We focused specifically on inter-individual differences and intra-individual changes over time by applying structural equation modeling, generalized linear models, and generalized estimating equations. Several weak inter-individual differences revealed that increased schizotypal signs are related to various childhood adversities, such as being repeatedly involved in fights and parents having severe conflicts among themselves. We also found a significant positive association between schizotypal signs and the total number of adversities a subject experienced. This pointed toward a modest dose-response relationship. The intra-individual change in schizotypal signs over time was rather weak, although some adjustment did occur. In contrast, inter-individual schizophrenia nuclear symptoms were mainly unrelated to childhood adversity. However, some striking intra-individual changes in distress were noted over time, especially those linked with severe punishment and the total adversity score. In conclusion, we have confirmed previous positive findings about the association between childhood adversity and subsequent subclinical psychosis symptoms: An increase in adversity is weakly related to an increase of the psychosis symptom load. However, depending on the kind of adversity experienced the psychosis symptom load decreases gradually in adult life. Copyright © 2014 Elsevier B.V. All rights reserved.

The joint contribution of maternal history of early adversity and adulthood depression to socioeconomic status and potential relevance for offspring development.

We examined the interactive effects of maternal childhood adversity and later adulthood depression on subsequent socioeconomic status (SES). Our community sample ranged from 230 to 243 mothers (across measures) drawn from a prospective, longitudinal cohort study. Maternal childhood adversity scores were derived using an integrated measure derived from the Childhood Trauma Questionnaire (CTQ) and the Parental Bonding Index (PBI). Maternal depression was measured in the prenatal period with the Center for Epidemiologic Studies Depression Scale (CES-D). SES measures included maternal highest level of education and family income as obtained prenatally. The analyses yielded significant interaction effects between maternal childhood adversity and prenatal depression that predicted income, prenatally. Women who reported higher levels of childhood adversity combined with higher levels of self-reported depressive symptoms were significantly more likely to live in low SES environments. Results also showed that level of education was predicted by childhood adversity independent of maternal symptoms of depression. The results suggest that SES is influenced by a life course pathway that begins in childhood and includes adversity-related mental health outcomes. Since child health and development is influenced by both maternal mental health and SES, this pathway may also contribute to the intergenerational transmission of the risk for psychopathology in the offspring. The results also emphasize the importance of studying potential precursors of low SES, a well-documented environmental risk factor for poor developmental outcomes in the offspring. Copyright © 2016.

The objective of this study was to evaluate whether modifiable cardiovascular risk conditions and lifestyle factors were temporally associated with an increased risk for ischemic heart disease and overall mortality in a cohort of hematopoietic cell transplantation (HCT) survivors. HCT recipients who had survived for ≥1 year, were ≥20 years old, and had undergone transplantation between 1970 and 2010 at a transplant referral center were surveyed in 2010-2011 about cardiovascular health and lifestyle factors (n = 3833). Respondents (n = 2360 [61.6%]) were followed to 2016 for incident ischemic heart disease and overall mortality. Among the 2360 transplant survivors (median age at the baseline survey, 55.9 years; median time since transplantation, 10.8 years), 162 (6.9%) reported ischemic heart disease at the baseline survey. Among those without ischemic heart disease at the baseline survey (n = 2198), the 5-year cumulative incidence of subsequent ischemic heart disease was 4.3%. Obesity, dyslipidemia, diabetes, and physical inactivity at baseline were associated with an increased risk for subsequent ischemic heart disease (hazard ratio [HRs] ≥ 1.8). Greater physical activity and fruit/vegetable intake at baseline were associated with subsequent lower overall mortality (HRs ≤ 0.7). When jointly considered, each additional cardiovascular risk condition and each adverse lifestyle factor were independently associated with subsequent ischemic heart disease (HR for risk conditions, 1.4; 95% confidence interval [CI], 1.0-1.9; HR for lifestyle factors, 1.9; 95% CI, 1.2-2.9), and adverse lifestyle factors remained associated with overall mortality (HR, 1.8; 95% CI, 1.5-2.3). These results support strong efforts to promote healthy lifestyle behaviors and to treat cardiovascular risk factors aggressively in HCT survivors. This may reduce future ischemic heart disease and overall mortality in this high-risk population. Cancer 2018;124:1507-15. © 2018 American Cancer Society. © 2018 American Cancer Society.

Adverse effects of gluten ingestion and advantages of gluten withdrawal in nonceliac autoimmune disease.

PubMed

Lerner, Aaron; Shoenfeld, Yehuda; Matthias, Torsten

2017-12-01

In light of the coincident surge in overall gluten intake and the incidence of autoimmune diseases, the possible biological adverse effects of gluten were explored. PubMed, MEDLINE, and the Cochrane Library databases were screened for reports published between 1964 and 2016 regarding the adverse effects of gluten as well as the effects of a gluten-free diet on autoimmune diseases. In vitro and in vivo studies describing gluten intake in animal models or cell lines and gluten-free diets in human autoimmune diseases were reviewed. Multiple detrimental aspects of gluten affect human health, including gluten-dependent digestive and extradigestive manifestations mediated by potentially immunological or toxic reactions that induce gastrointestinal inadequacy. Gluten affects the microbiome and increases intestinal permeability. It boosts oxidative stress and affects epigenetic behavior. It is also immunogenic, cytotoxic, and proinflammatory. Gluten intake increases apoptosis and decreases cell viability and differentiation. In certain nonceliac autoimmune diseases, gluten-free diets may help curtail the adverse effects of gluten. Additional in vivo studies are needed to unravel the puzzle of gluten effects in humans and to explore the potential beneficial effects of gluten-free diets in autoimmune diseases. © The Author(s) 2017.

The Lifetime Effect of Residential School Attendance on Indigenous Health Status

PubMed Central

2014-01-01

Objectives. I examined the health impact of lifetime Indian Residential school (IRS) attendance and the mediating influences of socioeconomic status and community adversity on health outcomes in a national sample of Aboriginal peoples in Canada. Methods. In an analysis of data on 13 881 Inuit, Métis, and off-reserve First Nations or North American Indian adults responding to the postcensus 2006 Aboriginal Peoples Survey administered October 2006 to March 2007, I tested the direct effect of IRS attendance on health and indirect effects through socioeconomic and community factors using logistic regression procedures. Results. Negative health status was significantly more likely with IRS attendance than nonattendance. The direct effect of IRS attendance remained significant although it attenuated substantially when adjusting for demographic characteristics, socioeconomic status, and community-level adversities. Community adversity and socioeconomic factors, primarily income, employment status, and educational attainment mediated the effect of IRS on health. Conclusions. Residential school attendance is a significant health determinant in the Indigenous population and is adversely associated with subsequent health status both directly and through the effects of attendance on socioeconomic and community-level risks.

A review of preserved and preservative-free prostaglandin analogues for the treatment of open-angle glaucoma and ocular hypertension.

PubMed

Hommer, A

2010-06-01

Glaucoma affects an increasing number of people worldwide and is the second leading cause of blindness. The aim of antiglaucoma therapy is to maintain a patient's visual function and quality of life. Prostaglandin analogues are first-line topical antiglaucoma therapy. They are effective at lowering intraocular pressure (IOP) and are generally well tolerated, with fewer systemic adverse events compared with the other classes. However, the use of prostaglandin analogues can be associated with ocular adverse effects, such as stinging/burning sensation, dry eyes, iris and periocular hyperpigmentation, and eye lash growth, which can affect patient compliance. Preservatives used in antiglaucoma preparations can have dose-dependent toxic effects, which contribute to adverse effects. The development of preservative-free preparations may reduce such adverse effects and therefore improve patient compliance. Tafluprost is a prostaglandin analogue in a preservative-free formulation that was recently approved for the reduction of elevated IOP in open-angle glaucoma and ocular hypertension.

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

The therapeutic equivalence of generic and brand antiepileptic drugs, based on studies performed on healthy volunteers, has been questioned. We compare, in a routine clinical setting, brand versus generic levetiracetam (LEV) bioequivalence in patients with epilepsy and also the clinical efficacy and tolerability of the substitution. A prospective, open-label, non-randomized, steady-state, multiple-dose, bioequivalence study was conducted in 12 patients with epilepsy (5 females), with a mean age of 38.4±16.2 years. Patients treated with the brand LEV (Keppra; UCB Pharma) were closely followed for a four-week period and subsequently switched to a generic LEV (Pharmaten) and followed for another four-week period. Blood samples were collected at the end of each 4-week period, during a dose interval for each formulation, for LEV concentration measurements by liquid chromatography mass spectrometry. Steady-state area under the curve (AUC) and peak plasma concentration (Cmax) data were subjected to conventional average bioequivalence analysis. Secondary clinical outcomes, including seizure frequency and adverse events, were recorded. Patients had epilepsy for a mean period of 14.1±10.6years and the mean daily LEV dose was 2583.3±763.7mg. The mean AUC±SD and Cmax±SD was 288.4±86.3(mg/L)h and 37.8±10.4mg/L respectively for brand LEV and 319.2±104.7(mg/L)h and 41.6±12.3mg/L respectively for the generic LEV. Statistic analysis showed no statistical significant difference in bioequivalence. Also, no change in seizures frequency and/or adverse events was recorded. In our clinical setting, generic LEV was determined to be bioequivalent to brand LEV. Furthermore, seizures frequency or/and adverse events were not affected upon switching from brand to generic LEV.

Background Bleeding following hospital discharge from percutaneous coronary intervention (PCI) is associated with increased risk of subsequent myocardial infarction (MI) and death, however the timing of adverse events following these bleeding events is poorly understood. Defining this relationship may help clinicians identify critical periods when patients are at highest risk. Methods and Results All patients undergoing PCI from 2004–2007 who survived to hospital discharge without a bleeding event were identified from the HMO Research Network-Stent Registry. Post-discharge rates and timing of bleeding-related hospitalizations, MI and death were defined. We then assessed the association between post-discharge bleeding-related hospitalizations with death and MI using Cox proportional hazards models. Among 8,137 post-PCI patients surviving to hospital discharge without in-hospital bleeding, 391 (4.8%) suffered bleeding-related hospitalization after discharge, with the highest incidence of bleeding-related hospitalizations occurring within 30 days of discharge (n=79, 20.2%). Post-discharge bleeding-related hospitalization after PCI was associated with subsequent death or MI (hazard ratio [HR] 3.09; 95% confidence interval [CI] 2.41–3.96), with the highest risk for death or MI occurring in the first 60 days after bleeding-related hospitalization (HR 7.16, CI 3.93–13.05). Conclusions Approximately 1 in 20 post-PCI patients are readmitted for bleeding, with the highest incidence occurring within 30 days of discharge. Patients suffering post-discharge bleeding are at increased risk for subsequent death or MI, with the highest risk occurring within the first 60 days following a bleeding-related hospitalization. These findings suggest a critical period after bleeding events when patients are most vulnerable for further adverse events. PMID:27301394

Weight of evidence evaluation of a network of adverse ...

EPA Pesticide Factsheets

Ongoing honey bee colony losses are of significant international concern because of the essential role these insects play in pollinating many high nutrient crops, such as fruits, vegetables, and nuts. Both chemical and non-chemical stressors have been implicated as possible contributors to colony failure, however, the potential role(s) of commonly-used neonicotinoid insecticides has emerged as particularly concerning. Neonicotinoids act on the nicotinic acetylcholine receptors (nAChRs) in the central nervous system to eliminate target pest insects. However, mounting evidence indicates that these neonicotinoids also may adversely affect beneficial pollinators, such as the honey bee, via impairments on learning and memory, and ultimately foraging success. The specific 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. The objective of this review was to develop adverse outcome pathways (AOPs) as a means to evaluate the biological plausibility and empirical evidence supporting (or refuting) the linkage between activation of the physiological target site, the nAChR, and colony level consequences. Development of 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 norm

Chronic lymphocytic leukemia (CLL) is a B-cell leukemia mainly affecting older adults. Historically, CLL has been regarded as an incurable disease, and treatment has been confined to cytotoxic chemotherapy regimens. However, prognosis for patients treated with these agents remained poor, prompting the development of new, targeted agents. The introduction of rituximab, a CD20-targeted monoclonal antibody, revolutionized the treatment for this disease. Rituximab in combination with fludarabine improved response rates and length of progression-free survival. The success of rituximab in this setting has prompted the development of many more investigational agents for CLL, including other antibody agents. However, as with any medication, the potential benefit achieved with CLL therapies is mitigated by the safety risk for the patient. These agents have been associated with adverse events such as immunosuppression, reactivation of cytomegalovirus, and infusion-related reactions that can occur with antibody administration. Adverse events can greatly affect the patient’s quality of life and ability to tolerate therapy. Management of adverse events is a critical component of the overall treatment strategy for CLL, particularly in elderly patients. In this clinical roundtable monograph, 3 expert physicians discuss the latest clinical studies evaluating the treatment of CLL, focusing on the adverse events associated with each agent and the potential interventions that can be used to manage their occurrence.

To determine if simulated, age-related changes in color vision can adversely affect one's ability to properly take medication as simulated by bead selection. Randomized controlled study. University site. University students 18 to 26 years of age without eye disorders that would affect color vision. Yellow-lens glasses to represent age-related color vision changes. The number of correct beads selected and rating of task difficulty. The secondary outcomes were participants' responses based on which colors and color pairs were most difficult to discern and strategies they might have used to select beads. The control group had no difficulties in selecting the appropriate beads, while the experimental group had significantly more mistakes, particularly with colors in the blue-violet spectrum. Average scores for the total number correct for the control and experimental groups were 36 (100%) and 27 (74.4%), P < 0.001, respectively, out of a possible 36 correct. Declines in color vision with age can adversely affect an individual's abilities to appropriately select medications. For patients taking several medications, declines in color vision should be considered when counseling older persons on strategies for compliance. Although more studies are still needed to further generalize these findings to the geriatric population, this study has shown color vision can adversely affect medication compliance.

This study examined negative and positive affect in relation to restrictive eating episodes (i.e., meals/snacks perceived as restrictive) and whether restrictive eating was associated with likelihood of subsequent eating disorder behaviors (i.e., additional restrictive eating, binge eating, vomiting, laxative use, weighing, exercising, meal skipping, drinking fluids to curb appetite, body checking). Women with anorexia nervosa (N = 118) completed a 2-week ecological momentary assessment protocol. For both restrictive and nonrestrictive eating, negative affect significantly increased from prebehavior to the time of the behavior but remained stable thereafter, while positive affect remained stable from prebehavior to the time of the behavior but decreased significantly thereafter. Across time, negative affect was significantly lower and positive affect was significantly greater in restrictive than nonrestrictive episodes. Engagement in restrictive eating was associated with an increased likelihood of subsequent restrictive eating, laxative use, and body checking, but not other behaviors. Engagement in nonrestrictive eating was associated with a decreased likelihood of subsequent restrictive eating, binge eating, vomiting, laxative use, weighing, meal skipping, drinking fluids to curb appetite, and body checking. Despite similar patterns of affect across eating episodes over time, results suggest affect may be involved in the maintenance of restrictive eating in anorexia nervosa since restrictive episodes were associated with lower negative and greater positive affect across time compared to nonrestrictive episodes. Further, while restrictive episodes increased the likelihood of only three subsequent eating disorder behaviors, nonrestrictive episodes were protective since they decreased likelihood of all but one behavior. © 2015 Wiley Periodicals, Inc.

To retrospectively determine whether extrinsic warming of the low-osmolality contrast material iopamidol to 37°C prior to intravenous administration at computed tomography (CT) affects extravasation and allergic-like reaction rates. The need to obtain informed patient consent was waived for this HIPAA-compliant and institutional review board-approved analysis. All adverse events related to the intravenous administration of iopamidol during CT examinations occurring 200 days before (period 1) and 200 days after (period 2) the cessation of extrinsic contrast material warming (37°C) for intravenous injections of less than 6 mL/sec at Duke University Medical Center (Durham, NC) were retrospectively reviewed. Adverse event rates were compared by using χ2 statistics. There were 12,682 injections during period 1 (10,831 injections of iopamidol 300 and 1851 injections of iopamidol 370) and 12,138 injections (10, 064 injections of iopamidol 300 and 2074 injections of iopamidol 370) during period 2. Adverse event rates for iopamidol 300 were not affected by extrinsic warming (extravasation rates: 0.30% [32 of 10,831] in period 1 vs 0.23% [23 of 10,064] in period 2, P=.64; allergic-like reaction rates: 0.39% [42 of 10,831] in period 1 vs 0.46% [46 of 10,064] in period 2, P=.74; overall adverse events: 0.68% [74 of 10,831] in period 1 vs 0.69% [69 of 10,064] in period 2, P=.99). Discontinuation of extrinsic warming was associated with significantly increased extravasation and overall adverse event rates for iopamidol 370 (extravasation rates: 0.27% [five of 1851] vs 0.87% [18 of 2074], P=.05; allergic-like reaction rates: 0.16% [three of 1851] vs 0.39% [eight of 2074], P=.42; overall adverse events: 0.43% [eight of 1851] vs 1.25% [26 of 2074], P=.02). Extrinsic warming (to 37°C) does not appear to affect adverse event rates for intravenous injections of iopamidol 300 of less than 6 mL/sec but is associated with a significant reduction in extravasation and overall adverse event rates for the more viscous iopamidol 370. © RSNA, 2011

Toddler Emotion Regulation with Mothers and Fathers: Temporal Associations Between Negative Affect and Behavioral Strategies

2010-01-01

The present study investigated temporal associations between putative emotion regulation strategies and negative affect in 20-month-old toddlers. Toddlers’ parent-focused, self-distraction, and toy-focused strategies, as well as negative affect, were rated on a second-by-second basis during laboratory parent-toddler interactions. Longitudinal mixed-effects models were conducted to determine the degree to which behavioral strategy use predicts subsequent negative affect and negative affect predicts subsequent strategy use. Results with mother-toddler and father-toddler dyads indicated that parent-focused strategies with an unresponsive parent were followed by increases in negative affect, whereas toy-focused strategies were followed by decreases in negative affect. Results also indicated that toddler negative affect serves to regulate behavioral strategy use within both parent contexts. PMID:21552335

Reclaimed tidal land soil (RTLS) often contains high levels of soluble salts and exchangeable Na that can adversely affect plant growth. The current study examined the effect of biochar on the physicochemical properties of RTLS and subsequently the influence on plant growth performance. Rice hull derived biochar (BC) was applied to RTLS at three different rates (1%, 2%, and 5% (w/w)) and maize (Zea mays L.) subsequently cultivated for 6weeks. While maize was cultivated, 0.1% NaCl solution was supplied from the bottom of the pots to simulate the natural RTLS conditions. Biochar induced changes in soil properties were evaluated by the water stable aggregate (WSA) percentage, exchangeable sodium percentage (ESP), soil organic carbon contents, cation exchange capacity, and exchangeable cations. Plant response was measured by growth rate, nutrient contents, and antioxidant enzyme activity of ascorbate peroxidase (APX) and glutathione reductase (GR). Application of rice hull derived biochar increased the soil organic carbon content and the percentage of WSA by 36-69%, while decreasing the ESP. The highest dry weight maize yield was observed from soil which received 5% BC (w/w), which was attributed to increased stability of water-stable aggregates and elevated levels of phosphate in BC incorporated soils. Moreover, increased potassium, sourced from the BC, induced mitigation of Na uptake by maize and consequently, reduced the impact of salt stress as evidenced by overall declines in the antioxidant activities of APX and GR.

Background Urinary incontinence is involuntary leakage of urine and can affect people of all ages. Incidence rises as people age, often because of reduced mobility or conditions affecting the nervous system, such as dementia and stroke. Urinary incontinence can be a distressing condition and can harm a person's physical, financial, social, and emotional well-being. People with urinary incontinence are susceptible to skin irritation, pressure sores, and urinary tract infections. Urinary incontinence is also associated with an increased risk of falls in older adults. This health technology assessment examined the effectiveness of, budget impact of, and patient values and preferences about electronic monitoring systems to assess urinary incontinence for residents of long-term care homes or geriatric hospital inpatients with complex conditions. Methods A clinical evidence review of the published clinical literature was conducted to June 9, 2017. Critical appraisal of the clinical evidence included assessment of risk of bias and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria to reflect the certainty of the evidence. We calculated the funding required for an electronic urinary incontinence monitoring system in the first year of implementation (when facilities would buy the systems) and in subsequent years. We interviewed six people with urinary incontinence and two caregivers, who described ways urinary incontinence affected daily life. Results We included one observational study in the clinical review. Most of the 31 participants in the observational study were female (78%) and required high levels of care, primarily because of cognitive impairment. The quality of evidence for all outcomes was very low owing to potential risk of bias and indirectness. We are consequently uncertain about how electronic monitoring systems affect management of urinary incontinence. For patients living in long-term care homes who are eligible for the technology, we estimated that an electronic monitoring system to assess urinary incontinence would cost $6.4 million in the first year of implementation and $1.6 million in subsequent years. Patients said urinary incontinence reduced their independence and social life and adversely affected their quality of life. Incontinence made them embarrassed and reduced their self-esteem. Several respondents mentioned how expensive supplies to manage incontinence were. Conclusions The effectiveness of using the electronic monitoring system to assess urinary incontinence is uncertain because of the very low quality of the evidence. Introducing electronic monitoring systems would result in incremental costs, and there would be savings only if the systems substantially reduced incontinence. PMID:29844845

Well-Being and Safety among Inpatient Psychiatric Staff: The Impact of Conflict, Assault, and Stress Reactivity

Kelly, Erin L.; Fenwick, Karissa; Brekke, John S.; Novaco, Raymond W.

2015-01-01

Psychiatric staff are faced with multiple forms of hostility, aggression, and assault at work, collectively referred to as workplace violence, which typically is activated by patients but can also come from coworkers and supervisors. Whether workplace violence adversely affects staff well-being may be related not only to its presence, but also to an individual’s stress reactivity. At a large public psychiatric hospital, an online survey was completed by 323 clinical care staff, of whom 69.5% had experienced physical assault in the previous 12 months. Staff well-being (depression, anger, and physical health) and staff safety concerns were adversely affected by conflicts with other staff members and by individual reactivity to social conflict and to assault. To improve staff well-being, in addition to safety protocols, interventions should target staff relationships, personal health maintenance practices, and individual coping skills for dealing with adverse workplace experiences.

Maternal obesity is a global epidemic affecting both developed and developing countries. Human and animal studies indicate that maternal obesity adversely programs the development of offspring, predisposing them to chronic diseases later in life. Several mechanisms act together to produce these adverse health effects. There is a consequent need for effective interventions that can be used in the management of human pregnancy to prevent these outcomes. The present review analyzes the dietary and exercise intervention studies performed to date in both altricial and precocial animals, rats and sheep, with the aim of preventing adverse offspring outcomes. The results of these interventions present exciting opportunities to prevent, at least in part, adverse metabolic and other outcomes in obese mothers and their offspring. © 2013 International Life Sciences Institute.

Which daily experiences can foster well-being at work? A diary study on the interplay between flow experiences, affective commitment, and self-control demands.

PubMed

Rivkin, Wladislaw; Diestel, Stefan; Schmidt, Klaus-Helmut

2018-01-01

Previous research has provided strong evidence for affective commitment as a direct predictor of employees' psychological well-being and as a resource that buffers the adverse effects of self-control demands as a stressor. However, the mechanisms that underlie the beneficial effects of affective commitment have not been examined yet. Drawing on the self-determination theory, we propose day-specific flow experiences as the mechanism that underlies the beneficial effects of affective commitment, because flow experiences as peaks of intrinsic motivation constitute manifestations of autonomous regulation. In a diary study covering 10 working days with N = 90 employees, we examine day-specific flow experiences as a mediator of the beneficial effects of interindividual affective commitment and a buffering moderator of the adverse day-specific effects of self-control demands on indicators of well-being (ego depletion, need for recovery, work engagement, and subjective vitality). Our results provide strong support for our predictions that day-specific flow experiences a) mediate the beneficial effects of affective commitment on employees' day-specific well-being and b) moderate (buffer) the adverse day-specific effects of self-control demands on well-being. That is, on days with high levels of flow experiences, employees were better able to cope with self-control demands whereas self-control demands translated into impaired well-being when employees experienced lower levels of day-specific flow experiences. We then discuss our findings and suggest practical implications. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Ozone reaction with interior building materials: Influence of diurnal ozone variation, temperature and humidity

Elevated tropospheric ozone concentrations are associated with increased morbidity and mortality. Indoor ozone chemistry affects human exposure to ozone and reaction products that also may adversely affect health and comfort. Reactive uptake of ozone has been characterized for many building materials; however, scant information is available on how diurnal variation of ambient ozone influences ozone reaction with indoor surfaces. The primary objective of this study is to investigate ozone-surface reactions in response to a diurnally varying ozone exposure for three common building materials: ceiling tile, painted drywall, and carpet tile. A secondary objective is to examine the effects of air temperature and humidity. A third goal is to explore how conditioning of materials in an occupied office building might influence subsequent ozone-surface reactions. Experiments were performed at bench-scale with inlet ozone concentrations varied to simulate daytime (ozone elevated) and nighttime (ozone-free in these experiments) periods. To simulate office conditions, experiments were conducted at two temperatures (22 °C and 28 °C) and three relative humidity values (25%, 50%, 75%). Effects of indoor surface exposures were examined by placing material samples in an occupied office and repeating bench-scale characterization after exposure periods of 1 and 2 months. Deposition velocities were observed to be highest during the initial hour of ozone exposure with slow decrease in the subsequent hours of simulated daytime conditions. Daily-average ozone reaction probabilities for fresh materials are in the respective ranges of (1.7-2.7) × 10-5, (2.8-4.7) × 10-5, and (3.0-4.5) × 10-5 for ceiling tile, painted drywall, and carpet tile. The reaction probability decreases by 7%-47% across the three test materials after two 8-h periods of ozone exposure. Measurements with the samples from an occupied office reveal that deposition velocity can decrease or increase with time. Influence of temperature and humidity on ozone-surface reactivity was not strong.

Closer supervision of residents' clinical activities has been promoted to improve patient safety, but may additionally affect resident participation in patient care and learning. The objective of this study was to determine the effects of closer supervision on patient care, resident participation, and the development of resident ability to care independently for critically ill patients during simulated scenarios. This quantitative study represents a component of a larger mixed-methods study. Residents were randomized to one of three levels of supervision, defined by the physical proximity of the supervisor (distant, immediately available, and direct). Each resident completed a simulation scenario under the supervision of a critical care fellow, immediately followed by a modified scenario of similar content without supervision. The simulation center of a tertiary, university-affiliated academic center in a large urban city. Fifty-three residents completing a critical care rotation and 24 critical care fellows were recruited between April 2009 and June 2010. None. During the supervised scenarios, lower team performance checklist scores were obtained for distant supervision compared with immediately available and direct supervision (mean [SD], direct: 72% [12%] vs immediately available: 77% [10%] vs distant: 61% [11%]; p = 0.0013). The percentage of checklist items completed by the residents themselves was significantly lower during direct supervision (median [interquartile range], direct: 40% [21%] vs immediately available: 58% [16%] vs distant: 55% [11%]; p = 0.005). During unsupervised scenarios, no significant differences were found on the outcome measures. Care delivered in the presence of senior supervising physicians was more comprehensive than care delivered without access to a bedside supervisor, but was associated with lower resident participation. However, subsequent resident performance during unsupervised scenarios was not adversely affected. Direct supervision of residents leads to improved care process and does not diminish the subsequent ability of residents to function independently.

Do night naps impact driving performance and daytime recovery sleep?

Short, nighttime naps are used as a fatigue countermeasure in night shift work, and may offer protective benefits on the morning commute. However, there is a concern that nighttime napping may impact upon the quality of daytime sleep. The aim of the current project was to investigate the influence of short nighttime naps (<30min) on simulated driving performance and subsequent daytime recovery sleep. Thirty-one healthy subjects (aged 21-35 y; 18 females) participated in a 3-day laboratory study. After a 9-h baseline sleep opportunity (22:00h-07:00h), subjects were kept awake the following night with random assignment to: a 10-min nap ending at 04:00h plus a 10-min nap at 07:00h; a 30-min nap ending at 04:00h; or a no-nap control. A 40-min driving simulator task was administered at 07:00h and 18:30h post-recovery sleep. All conditions had a 6-h daytime recovery sleep opportunity (10:00h-16:00h) the next day. All sleep periods were recorded polysomnographically. Compared to control, the napping conditions did not significantly impact upon simulated driving lane variability, percentage of time in a safe zone, or time to first crash on morning or evening drives (p>0.05). Short nighttime naps did not significantly affect daytime recovery total sleep time (p>0.05). Slow wave sleep (SWS) obtained during the 30-min nighttime nap resulted in a significant reduction in SWS during subsequent daytime recovery sleep (p<0.05), such that the total amount of SWS in 24-h was preserved. Therefore, short naps did not protect against performance decrements during a simulated morning commute, but they also did not adversely affect daytime recovery sleep following a night shift. Further investigation is needed to examine the optimal timing, length or combination of naps for reducing performance decrements on the morning commute, whilst still preserving daytime sleep quality.

The environmental and health consequences of climate change, which disproportionately affect low-income countries and poor people in high-income countries, profoundly affect human rights and social justice. Environmental consequences include increased temperature, excess precipitation in some areas and droughts in others, extreme weather events, and increased sea level. These consequences adversely affect agricultural production, access to safe water, and worker productivity, and, by inundating land or making land uninhabitable and uncultivatable, will force many people to become environmental refugees. Adverse health effects caused by climate change include heat-related disorders, vector-borne diseases, foodborne and waterborne diseases, respiratory and allergic disorders, malnutrition, collective violence, and mental health problems. These environmental and health consequences threaten civil and political rights and economic, social, and cultural rights, including rights to life, access to safe food and water, health, security, shelter, and culture. On a national or local level, those people who are most vulnerable to the adverse environmental and health consequences of climate change include poor people, members of minority groups, women, children, older people, people with chronic diseases and disabilities, those residing in areas with a high prevalence of climate-related diseases, and workers exposed to extreme heat or increased weather variability. On a global level, there is much inequity, with low-income countries, which produce the least greenhouse gases (GHGs), being more adversely affected by climate change than high-income countries, which produce substantially higher amounts of GHGs yet are less immediately affected. In addition, low-income countries have far less capability to adapt to climate change than high-income countries. Adaptation and mitigation measures to address climate change needed to protect human society must also be planned to protect human rights, promote social justice, and avoid creating new problems or exacerbating existing problems for vulnerable populations.

Childhood adversity increases the risk for cardiovascular disease (CVD) in adulthood. Previously proposed mechanisms suggest that the association is mediated by stress reactivity-known to be higher in women-and is aggravated by adult stress, but this has not yet been confirmed. Therefore, we investigated sex differences to better understand possible pathways from childhood adversity to CVD. The National Population Health Survey, a 15-year cohort study of Canadians aged 18-49 years at baseline was used. Logistic regression with interaction terms for sex and stressful life events was used to assess the risk of CVD after childhood adversity. In secondary analyses, we assessed mediation effects of depression, smoking, alcohol, exercise, and diet using the product of coefficient approach. Mediated moderation was subsequently used to explain sex-moderated effects. There was a strong association between childhood adversity and CVD (odds ratio [OR], 2.14; 95% confidence interval [CI], 1.56-2.94) for 3+ childhood adversities. The association was stronger with increasing stressful events, and female patients with 3+ stressful events exhibited the highest risk of CVD (OR, 4.40; 95% CI, 1.98-9.75). No association was found in men. Depression, smoking, and poor diet partially mediated the relationship between childhood adversity and CVD (14%, 9%, and 9%, respectively), but differences in these behaviours did not fully explain the sex-specific differences in the mediated moderation analysis. The effect of childhood adverse events on CVD is heightened among women, particularly women with stressful adulthoods, and this difference is not mediated by depression, smoking, or poor diet. These findings have important implications for understanding sex differences in CVD risk. Copyright © 2017 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.

Contrast media are used widely to improve medical imaging. Like all other pharmaceuticals, these agents are not completely devoid of risk, and continuous monitoring of adverse reactions with these agents is important. Spontaneous reporting is the simplest method for understanding the safety profile of pharmaceutical products after their approval. Our objective was to identify the pattern and characteristics of adverse reactions attributed to contrast media in the Indian population reported to the National Coordination Centre for the Pharmacovigilance Programme of India (NCC-PvPI). Individual case safety reports (ICSRs) attributed to contrast media submitted spontaneously to the NCC-PvPI were extracted from the database for July 2010 to September 2013. We analysed these reports for information related to reporter's professional category, patient's age and sex, reporter's diagnosis of the reaction, seriousness of the reaction, type of contrast media exposure, system organ class (SOC) affected (as described in World Health Organization Adverse Reaction Terminology [WHO-ART]) and outcome. Of the total 59,915 ICSRs in the database, 415 (0.7%) were suspected adverse reactions to contrast media; 44 reports were serious, including three fatal cases. The most affected SOCs were skin and appendage disorders, body as a whole-general disorders, gastrointestinal system disorders and respiratory system disorders. Hypersensitivity reactions were reported in the majority of ICSRs. The contrast media with the highest number of reports were iohexol (40.7%), iomeprol (17.8%), iopamidol (12%) and diatrizoate (12%). Most of the reactions to contrast media were allergic-like, and no previously unrecognised adverse reactions were observed in the Indian population. Further data and increased awareness among healthcare professionals is required to signal and prevent the consequences of adverse reactions attributed to contrast media.

Conflicting evidence exists on the efficacy and safety of bivalirudin administered as part of percutaneous coronary intervention (PCI) in patients with an acute coronary syndrome. We randomly assigned 7213 patients with an acute coronary syndrome for whom PCI was anticipated to receive either bivalirudin or unfractionated heparin. Patients in the bivalirudin group were subsequently randomly assigned to receive or not to receive a post-PCI bivalirudin infusion. Primary outcomes for the comparison between bivalirudin and heparin were the occurrence of major adverse cardiovascular events (a composite of death, myocardial infarction, or stroke) and net adverse clinical events (a composite of major bleeding or a major adverse cardiovascular event). The primary outcome for the comparison of a post-PCI bivalirudin infusion with no post-PCI infusion was a composite of urgent target-vessel revascularization, definite stent thrombosis, or net adverse clinical events. The rate of major adverse cardiovascular events was not significantly lower with bivalirudin than with heparin (10.3% and 10.9%, respectively; relative risk, 0.94; 95% confidence interval [CI], 0.81 to 1.09; P=0.44), nor was the rate of net adverse clinical events (11.2% and 12.4%, respectively; relative risk, 0.89; 95% CI, 0.78 to 1.03; P=0.12). Post-PCI bivalirudin infusion, as compared with no infusion, did not significantly decrease the rate of urgent target-vessel revascularization, definite stent thrombosis, or net adverse clinical events (11.0% and 11.9%, respectively; relative risk, 0.91; 95% CI, 0.74 to 1.11; P=0.34). In patients with an acute coronary syndrome, the rates of major adverse cardiovascular events and net adverse clinical events were not significantly lower with bivalirudin than with unfractionated heparin. The rate of the composite of urgent target-vessel revascularization, definite stent thrombosis, or net adverse clinical events was not significantly lower with a post-PCI bivalirudin infusion than with no post-PCI infusion.

2009-05-01

The adverse effects of water repellent soils on vadose zone hydrology are being increasingly identified worldwide in both rural and urban landscapes. Among the affected landscapes are agricultural fields, forests, effluent application sites, golf greens, wetlands, and wildfire sites. In spite of cross-discipline research efforts put forth in recent years, understanding of fundamental parameters controlling soil water behaviour in these systems is lacking. This is due, in part, to inherent complexities of water repellent soil systems and logistical shortcomings of methods commonly used by researchers in-situ and in the lab. As a result, modeling flow in these systems has further proven to be a difficult task. The objectives of our study were 1) to systematically measure and quantify water infiltration and distribution in dynamic water repellent systems and 2) to identify fundamental hydraulic behaviours that lead to the expression of changes in soil water repellency. To achieve this, we combined techniques to elucidate soil- water interactions at a post-wildfire site. Field tests and subsequent lab work reveal essential hydrological information on fire-affected water repellent soils at variable scales and under different burn conditions. Through the use of traditional and newer techniques, our work shows unique and previously unreported behaviour of soil water in these systems. We also address limitations of current field methods used to study repellency and associated infiltration behaviours.

Adverse early life experiences can potentially increase risk for drug abuse later in life. However, little research has been conducted studying the effects of maternal separation (MS), an experimental model for early life stress, on the rewarding effects of nicotine. Cognitive function may be affected by MS. So, we also investigated whether nicotine administration affect spatial learning and memory in MS adolescent female rats. Rat pups were subjected to daily MS for 15min (MS15) or 180min (MS180) during the first 2 weeks of life or reared under normal animal facility rearing (AFR) conditions. The place preference test was performed with nicotine (0.6mg/kg,s.c.) or vehicle over a period of 6 conditioning trials during adolescence. Spatial learning and memory performance was evaluated by using Morris water maze (MWM). In our study, adolescent female rats exposed to MS180 shown a significantly greater preference for a nicotine-paired compartment during the testing phase than the MS15 group. Nicotine altered the MS-induced spatial learning defects in the MS180 group. These findings suggest that MS may increase sensitivity to the rewarding effects of nicotine and also it is possible to suggest that nicotine administration may influence learning dysfunction induced by MS in adolescent female rats.

Window and Overlap Processing Effects on Power Estimates from Spectra

NASA Astrophysics Data System (ADS)

Trethewey, M. W.

2000-03-01

Fast Fourier transform (FFT) spectral processing is based on the assumption of stationary ergodic data. In engineering practice, the assumption is often violated and non-stationary data processed. Data windows are commonly used to reduce leakage by decreasing the signal amplitudes near the boundaries of the discrete samples. With certain combinations of non-stationary signals and windows, the temporal weighting may attenuate important signal characteristics to adversely affect any subsequent processing. In other words, the window artificially reduces a significant section of the time signal. Consequently, spectra and overall power estimated from the affected samples are unreliable. FFT processing can be particularly problematic when the signal consists of randomly occurring transients superimposed on a more continuous signal. Overlap processing is commonly used in this situation to improve the estimates. However, the results again depend on the temporal character of the signal in relation to the window weighting. A worst-case scenario, a short-duration half sine pulse, is used to illustrate the relationship between overlap percentage and resulting power estimates. The power estimates are shown to depend on the temporal behaviour of the square of overlapped window segments. An analysis shows that power estimates may be obtained to within 0.27 dB for the following windows and overlap combinations: rectangular (0% overlap), Hanning (62.5% overlap), Hamming (60.35% overlap) and flat-top (82.25% overlap).

Surface water, often used for irrigation purposes, may sometimes be contaminated with blooming cyanobacteria and thereby may contain their potent and harmful toxins. Cyanotoxins adversely affect many terrestrial plants, and accumulate in plant tissues that are subsequently ingested by humans. Studies were undertaken to (1) examine the bioaccumulation of microcystins (MCs) in leaves and fruits of pepper Capsicum annuum and (2) examine the potential effects of MCs on antioxidant capacity of these organs. Plants were irrigated with water containing MCs for a period of 3 mo. Data showed that MCs did not accumulate in leaves; however, in fruits the presence of the MC-LR (0.118 ng/mg dry weight) and dmMC-LR (0.077 ng/mg dry weight) was detected. The concentrations of MC-LR in fruit approached the acceptable guideline values and tolerable daily intake for this toxin. Lipid peroxidation levels and flavonoids content were significantly enhanced in both organs of treated plants, while total phenolic concentrations were not markedly variable between control and treated plants. Significant decrease in 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging capacity was noted for both organs. The levels of superoxide anion in fruits and hydroxyl radical in leaves were markedly reduced. Data suggest that exposure to MCs significantly reduced antioxidant capacity of experimental plants, indicating that MCs affected antioxidant systems in C. annuum.

Krasin, Matthew J., E-mail: matthew.krasin@stjude.org; Wiese, Kristin M.; Spunt, Sheri L.

Purpose: To investigate the relationship between jaw function, patient and treatment variables, and radiation dosimetry of the mandibular muscles and joints in children and young adults receiving radiation for soft-tissue and bone sarcomas. Methods and Materials: Twenty-four pediatric and young adult patients with head-and-neck sarcomas were treated on an institutional review board-approved prospective study of focal radiation therapy for local tumor control. Serial jaw depression measurements were related to radiation dosimetry delivered to the medial and lateral pterygoid muscles, masseter muscles, and temporomandibular joints to generate mathematical models of jaw function. Results: Baseline jaw depression was only influenced by themore » degree of surgical resection. In the first 12 weeks from initiation of radiation, surgical procedures greater than a biopsy, administration of cyclophosphamide containing chemotherapy regimes, and large gross tumor volumes adversely affected jaw depression. Increasing dose to the pterygoid and masseter muscles above 40 Gy predicted loss of jaw function over the full course of follow-up. Conclusions: Clinical and treatment factors are related to initial and subsequent jaw dysfunction. Understanding these complex interactions and the affect of specific radiation doses may help reduce the risk for jaw dysfunction in future children and young adults undergoing radiation therapy for the management of soft-tissue and bone sarcomas.« less

Brood comb as a humidity buffer in honeybee nests

Adverse environmental conditions can be evaded, tolerated or modified in order for an organism to survive. During their development, some insect larvae spin cocoons which, in addition to protecting their occupants against predators, modify microclimatic conditions, thus facilitating thermoregulation or reducing evaporative water loss. Silk cocoons are spun by honeybee ( Apis mellifera) larvae and subsequently incorporated into the cell walls of the wax combs in which they develop. The accumulation of this hygroscopic silk in the thousands of cells used for brood rearing may significantly affect nest homeostasis by buffering humidity fluctuations. This study investigates the extent to which the comb may influence homeostasis by quantifying the hygroscopic capacity of the cocoons spun by honeybee larvae. When comb containing cocoons was placed at high humidity, it absorbed 11% of its own mass in water within 4 days. Newly drawn comb composed of hydrophobic wax and devoid of cocoons absorbed only 3% of its own mass. Therefore, the accumulation of cocoons in the comb may increase brood survivorship by maintaining a high and stable humidity in the cells.

To determine the effects of erectile dysfunction and to explore the impact of treatment with sildenafil (Viagra). An exploratory qualitative study with semistructured interviews. Men's health clinic in NHS hospital. 40 men who had had erectile dysfunction and had attended the clinic during the year before interview. Impact of erectile dysfunction on men, their expectations of sildenafil, and impact of treatment on men and their relationships. Issues explored with exploratory qualitative approach. Erectile dysfunction caused serious distress to all those men who experienced it, with marked effects on their self esteem and their relationships. Sildenafil, when it worked, caused a great improvement in wellbeing. The expectations raised by media hyperbole with the launch of sildenafil had an adverse effect on the morale of those who found it did not work. When, according to the patient, treatment did not work, the distress was severe and for many confirmed their lack of self worth. Further study is needed to explore the feelings of men affected by erectile dysfunction and their perception of treatment. Health professionals should be aware of the extreme distress erectile dysfunction can cause.

Adhesion barriers at cesarean delivery: advertising compared with the evidence.

PubMed

Albright, Catherine M; Rouse, Dwight J

2011-07-01

Cesarean delivery, the most common surgery performed in the United States, is complicated by adhesion formation in 24-73% of cases. Because adhesions have potential sequelae, different synthetic adhesion barriers are currently heavily marketed as a means of reducing adhesion formation resultant from cesarean delivery. However, their use for this purpose has been studied in only two small, nonblinded and nonrandomized trials, both of which were underpowered and subject to bias. Neither demonstrated improvement in meaningful clinical outcomes. In the only cost-effectiveness analysis of adhesion barriers to date, the use of synthetic adhesion barriers was cost-effective only when the subsequent rate of small bowel obstruction was at least 2.4%, a rate far higher than that associated with cesarean delivery. In fact, intra-abdominal adhesions from prior cesarean delivery rarely cause maternal harm and have not been demonstrated to adversely affect perinatal outcome. Based on our review of the available literature, we think the use of adhesion barriers at the time of cesarean delivery would be ill-advised at the present time.

The present study involves the estimation of ring tensile properties of Indian Pressurised Heavy Water Reactor (IPHWR) fuel cladding made of Zircaloy-4, subjected to experiments under a simulated loss-of-coolant-accident (LOCA) condition. Isothermal steam oxidation experiments were conducted on clad tube specimens at temperatures ranging from 900 to 1200 °C at an interval of 50 °C for different soaking periods with subsequent quenching in water at ambient temperature. The specimens, which survived quenching, were then subjected to ambient temperature ring tension test (RTT). The microstructure was correlated with the mechanical properties. The yield strength (YS) and ultimate tensile strength (UTS) increased initially with rise in oxidation temperature and time duration but then decreased with further increase in oxidation. Ductility is adversely affected with rising oxidation temperature and longer holding time. A higher fraction of load bearing phase and lower oxygen content in it ensures higher residual ductility. Cladding shows almost zero ductility behavior in RIT when load bearing phase fraction is less than 0.72 and its average oxygen concentration is greater than 0.58 wt%.

Bubble Transport through Micropillar Arrays

Lee, Kenneth; Savas, Omer

2012-11-01

In current energy research, artificial photosynthetic devices are being designed to split water and harvest hydrogen gas using energy from the sun. In one such design, hydrogen gas bubbles evolve on the catalytic surfaces of arrayed micropillars. If these bubbles are not promptly removed from the surface, they can adversely affect gas evolution rates, water flow rates, sunlight capture, and heat management of the system. Therefore, an efficient method of collecting the evolved gas bubbles is crucial. Preliminary flow visualization has been conducted of bubbles advecting through dense arrays of pillars. Bubbles moving through square and hexagonal arrays are tracked, and the results are qualitatively described. Initial attempts to correlate bubble motion with relevant lengthscales and forces are also presented. These observations suggest how bubble transport within such pillar arrays can be managed, as well as guide subsequent experiments that investigate bubble evolution and collection. This material is based upon work performed by the Joint Center for Artificial Photosynthesis, a DOE Energy Innovation Hub, supported through the Office of Science of the U.S. Department of Energy under Award Number DE-SC0004993.

Pneumocystis jiroveci pneumonia in patients receiving dasatinib treatment.

2014-08-01

Dasatinib may cause various adverse effects such as myelosuppression and pleural effusion. It is well known that dasatinib may affect cellular immunity, which leads to the subsequent risk of a myriad of infections and viral reactivations, especially cytomegalovirus. Pneumocystis jiroveci pneumonia (PJP) is an opportunistic infection that typically occurs in immunocompromised hosts. Although pneumonia is not uncommon among dasatinib-treated patients, dasatinib-associated PJP has been reported only once in the literature, without a description of the clinical details. We report herein two cases of PJP in patients receiving treatment containing dasatinib. One patient developed PJP at 7 months following dasatinib in combination with chemotherapy for the treatment of acute lymphoblastic leukemia. The other patient developed pleural effusion and PJP at 2 years following dasatinib treatment for chronic myeloid leukemia. Both patients recovered well after management with sulfamethoxazole/trimethoprim. Our experience illustrates that PJP is a potentially important complication of dasatinib-based treatment. Raising clinical awareness is important as prompt diagnosis and timely management are the cornerstones of successful treatment. Copyright © 2014 The Authors. Published by Elsevier Ltd..

Lisiecki, Marek; Paszkowski, Maciej; Woźniak, Sławomir

2017-12-01

Uterine fibroids (also known as leiomyomas or myomas) are the most common benign tumors affecting reproductive organs in women. They are monoclonal tumors of the uterine smooth muscle, which spring from myometrium. It is estimated that they occur in 50-60% of the female population and rise to 70% by the age of 50. While mostly asymptomatic, myomas can be connected with several conditions, including abnormal bleeding with subsequent anemia, pelvic masses, pelvic pain, bulk symptoms, unfavorable impact on fertility and obstetric complications. Factors, which predispose the emergence of fibroids are: hormones, Afro-American ethnicity, age, obesity, adverse pregnancy outcome history, early menarche, genetic factors, alcohol, caffeine or eating too much red meat. On the other hand, there are factors, which can decrease this risk: pregnancy, early menopause and tobacco smoking. There are several mechanisms of fertility impairment in females with fibroids: alternations in uterus function (flawed blood supply, increased contractility), changes in the normal uterus anatomy, local hormonal changes induced by fibroids. In this review the connection between fibroids and infertility is analyzed.

Exposure to endocrine-disrupting chemicals may adversely affect animals, particularly during development. Tris(1,3-dichloroisopropyl) phosphate (TDCIPP) is an organophosphate with anti-androgen function in vitro that is present in indoor dust at relatively high concentrations. In male rats, androgens are necessary for the development of reproductive organs, as well as the endocrine and central nervous systems. However, we currently do not know the exact effects of TDCIPP exposure through suckling on subsequent reproductive behavior in males. Here, we show that TDCIPP exposure (25-250 mg kg -1 via oral administration over 28 consecutive days post-birth) suppressed male sexual behavior and reduced testes size. These changes were dose-dependent and appeared first in adults rather than in juveniles. These results demonstrate that TDCIPP exposure led to normal body growth and appearance in juveniles, but disrupted the endocrine system and physiology in adults. Therefore, assays should be performed using adult animals to ensure accuracy, and to confirm the influence of chemical substances given during early mammalian life.

Background Strong epidemiologic evidence correlates tobacco use with a variety of serious adverse health effects, but the biological mechanisms that produce these effects remain elusive. Results We analyzed gene transcription data to identify expression spectra related to tobacco use in circulating leukocytes of 67 Caucasian male subjects. Levels of cotinine, a nicotine metabolite, were used as a surrogate marker for tobacco exposure. Significance Analysis of Microarray and Gene Set Analysis identified 109 genes in 16 gene sets whose transcription levels were differentially regulated by nicotine exposure. We subsequently analyzed this gene set by hyperclustering, a technique that allows the data to be clustered by both expression ratio and gene annotation (e.g. Gene Ontologies). Conclusion Our results demonstrate that tobacco use affects transcription of groups of genes that are involved in proliferation and apoptosis in circulating leukocytes. These transcriptional effects include a repertoire of transcriptional changes likely to increase the incidence of neoplasia through an altered expression of genes associated with transcription and signaling, interferon responses and repression of apoptotic pathways.

Land plants are sessile organisms that cannot escape the adverse climatic conditions of a given environment. Hence, adaptation is one of the solutions to surviving in a challenging environment. This study was aimed at detecting adaptive loci in barley landraces that are affected by selection. To that end, a diverse population of barley landraces was analyzed using the genotyping by sequencing approach. Climatic data for altitude, rainfall and temperature were collected from 61 weather sites near the origin of selected landraces across Ethiopia. Population structure analysis revealed three groups whereas spatial analysis accounted significant similarities at shorter geographic distances (< 40 Km) among barley landraces. Partitioning the variance between climate variables and geographic distances indicated that climate variables accounted for most of the explainable genetic variation. Markers by climatic variables association analysis resulted in altogether 18 and 62 putative adaptive loci using Bayenv and latent factor mixed model (LFMM), respectively. Subsequent analysis of the associated SNPs revealed putative candidate genes for plant adaptation. This study highlights the presence of putative adaptive loci among barley landraces representing original gene pool of the farming communities. PMID:26483825

The potential of ethylene oxide (EtO) residues in exposed plastic tissue culture dishes to adversely affect bovine oocyte maturation, fertilization and subsequent embryonic development was monitored. In experiment 1, the effects of aeration time and aeration combined with washing of EtO-gassed culture dishes on the extent of residual toxicity were investigated. There was no cleavage in any treatment in which oocytes were matured and fertilized in dishes exposed to EtO. EtO residues caused functional degeneration of oocytes even when culture dishes were aerated for more than 12 days post EtO-exposure and repeatedly washed. In experiment 2, the residual toxicity of EtO gas on in vitro maturation (IVM), in vitro fertilization (IVF) and in vitro culture (IVC) were evaluated. Cleavage rate significantly decreased and post-cleavage development was retarded in ova maintained in dishes treated with EtO either during IVM or IVF. EtO residues may be more detrimental to spermatozoa than to oocytes which may have been the primary cause of fertilization failure during IVF.

Sublethal Effects of Fenoxycarb on the Plutella xylostella (Lepidoptera: Plutellidae).

The effects of fenoxycarb, a Juvenile hormone analogue, at sublethal concentrations were tested on some biological parameters of Plutella xylostella (L.) in two consecutive generations. The calculated LC10, LC25, and LC50 values of the insecticide were 21.58, 43.25, and 93.62 mg/liter on third-instar larvae, respectively. Fenoxycarb significantly reduced pupal weight and oviposition period in parent generation. In addition, the fecundity of treated groups (LC10 = 71.06, LC25 = 40.60 eggs per female) in parents was significantly lower than control (169.40 eggs per female). Although fenoxycarb could not affect gross reproductive rate and death rate, it decreased net reproductive rate, intrinsic rate of increase, finite rate of increase, and birth rate in offspring generation. Also, mean generation time and doubling time of treated insects was significantly longer than control at LC10 level. Therefore, the data from this study suggested that fenoxycarb could adversely cause population decline in the subsequent generation. © The Author 2015.

LED Device Illuminates New Path to Healing

NASA Technical Reports Server (NTRS)

2008-01-01

Among NASA s research goals is increased understanding of factors affecting plant growth, including the effects of microgravity. Impeding such studies, traditional light sources used to grow plants on Earth are difficult to adapt to space flight, as they require considerable amounts of power and produce relatively large amounts of heat. As such, an optimized experimental system requires much less energy and reduces temperature variance without negatively affecting plant growth results. Ronald W. Ignatius, founder and chairman of the board at Quantum Devices Inc. (QDI), of Barneveld, Wisconsin, proposed using light-emitting diodes (LEDs) as the photon source for plant growth experiments in space. This proposition was made at a meeting held by the Wisconsin Center for Space Automation and Robotics, a NASA-sponsored research center that facilitates the commercialization of robotics, automation, and other advanced technologies. The Wisconsin group teamed with QDI to determine whether an LED system could provide the necessary wavelengths and intensities for photosynthesis, and the resultant system proved successful. The center then produced the Astroculture3, a plant growth chamber that successfully incorporated this LED light source, which has now flown on several space shuttle missions. NASA subsequently identified another need that could be addressed with the use of LEDs: astronaut health. A central concern in astronaut health is maintaining healthy growth of cells, including preventing bone and muscle loss and boosting the body s ability to heal wounds all adversely affected by prolonged weightlessness. Thus, having determined that LEDs can be used to grow plants in space, NASA decided to investigate whether LEDs might be used for photobiomodulation therapy (PBMT).

Multiple cross-sectional studies have linked adverse childhood events and adult adversities to current smoking, lifetime smoking, and former smoking. To date, however, there have been no direct observational studies assessing the influence of adversities on smoking relapse. We prospectively followed 123 participants, 86 of whom were habitual smokers, from pre-quit ad libitum smoking to four weeks post-quit. Thirty-seven non-smokers were also tested in parallel as a comparison group. Subjects provided biological samples for confirmation of abstinence status and self-report history of adversities such as abuse, neglect, family dysfunction, incarceration, and child-parent separation. They also completed mood and smoking withdrawal symptom measures. The results indicated that within non-smokers and smokers who relapsed within the first month of a quit attempt, but not abstainers, females had significantly higher adversity scores than males. Cigarette craving, which was independent from depressive affect, increased for low adversity participants, but not those with no adversity nor high adversity. These results demonstrate that sex and relapse status interact to predict adversity and that craving for nicotine may be an important additional mediator of relapse. These results add further support to the previous cross-sectional evidence of an adversity and smoking relationship. Further studies to clarify how adversity complicates smoking cessation and impacts smoking behaviors are warranted. Copyright © 2016 Elsevier Ltd. All rights reserved.

Management options are limited for the treatment of Graves' disease, and there is controversy regarding optimal treatment. We describe the demographic and biochemical characteristics of children with Graves' disease and the outcomes of its management. This is a retrospective study reviewing medical records from 2001 to 2011 at a tertiary-care paediatric hospital. Diagnostic criteria included elevated free T4 and total T3, suppressed TSH, and either positive thyroid-stimulating immunoglobulin or thyroid receptor antibodies or clinical signs suggestive of Graves' disease, for example exophthalmos. Patients were treated with antithyroid drugs (ATD), radioactive iodine, or thyroidectomy. The main outcome measures were remission after medical therapy for at least 6 months and subsequent relapse. A total of 291 children met diagnostic criteria. A total of 62 were male (21%); 117 (40%) were Hispanic, 90 (31%) Caucasian, and 59 (20%) African American. Mean age (±standard deviation) at diagnosis was 12·3 ± 3·8 (range 3-18·5) years. At diagnosis, 268 patients were started on an antithyroid drug and 23 underwent thyroid ablation or thyroidectomy. Fifty-seven (21%) children achieved remission and 16 (28%) of these patients relapsed, almost all within 16 months. Gender and ethnicity did not affect rates of remission or relapse. Of 251 patients treated with methimazole, 53 (21%) had an adverse reaction, including rash, arthralgias, elevated transaminases, or neutropenia. Most children with Graves' disease treated with ATD do not experience remission, but most remissions do not end in relapse. Adverse reactions to methimazole are common but generally mild. © 2016 John Wiley & Sons Ltd.

The assault and subsequent collapse of the World Trade Center towers in New York City on September 11, 2001 (9/11), released more than a million tons of debris and dust into the surrounding area, engulfing rescue workers as they rushed to aid those who worked in the towers, and the thousands of nearby civilians and children who were forced to flee. In December 2015, almost 15 years after the attack, and 5 years after first enactment, Congress reauthorized the James Zadroga 9/11 Health and Compensation Act, a law designed to respond to the adverse health effects of the disaster. This reauthorization affords an opportunity to review human inhalation exposure science in relation to the World Trade Center collapse. In this Special Article, we compile observations regarding the collective medical response to the environmental health disaster with a focus on efforts to address the adverse health effects experienced by nearby community members including local residents and workers. We also analyze approaches to understanding the potential for health risk, characterization of hazardous materials, identification of populations at risk, and shortfalls in the medical response on behalf of the local community. Our overarching goal is to communicate lessons learned from the World Trade Center experience that may be applicable to communities affected by future environmental health disasters. The World Trade Center story demonstrates that communities lacking advocacy and preexisting health infrastructures are uniquely vulnerable to health disasters. Medical and public health personnel need to compensate for these vulnerabilities to mitigate long-term illness and suffering.

Environmental chemicals are known to disrupt the endocrine system in humans and to have adverse effects on several organs including the developing brain. Recent studies indicate that exposure to environmental chemicals during gestation can interfere with neuronal differentiation, subsequently affecting normal brain development in newborns. Xenoestrogen, bisphenol A (BPA), which is widely used in plastic products, is one such chemical. Adverse effects of exposure to BPA during pre- and postnatal periods include the disruption of brain function. However, the effect of BPA on neural differentiation remains unclear. In this study, we explored the effects of BPA or bisphenol F (BPF), an alternative compound for BPA, on neural differentiation using ReNcell, a human fetus-derived neural progenitor cell line. Maintenance in growth factor-free medium initiated the differentiation of ReNcell to neuronal cells including neurons, astrocytes, and oligodendrocytes. We exposed the cells to BPA or BPF for 3 days from the period of initiation and performed real-time PCR for neural markers such as β III-tubulin and glial fibrillary acidic protein (GFAP), and Olig2. The β III-tubulin mRNA level decreased in response to BPA, but not BPF, exposure. We also observed that the number of β III-tubulin-positive cells in the BPA-exposed group was less than that of the control group. On the other hand, there were no changes in the MAP2 mRNA level. These results indicate that BPA disrupts neural differentiation in human-derived neural progenitor cells, potentially disrupting brain development.

Chronic stress in humans can result in multiple adverse psychiatric and neurobiological outcomes, including memory deficits. These adverse outcomes can be more severe if each episode of stress is very traumatic. When compared to acute or short term stress relatively little is known about the effects of chronic traumatic stress on memory and molecular changes in hippocampus, a brain area involved in memory processing. Here we studied the effects of chronic traumatic stress in mice by exposing them to adult Long Evan rats for 28 consecutive days and subsequently analyzing behavioral outcomes and the changes in the hippocampus. Results show that stressed mice developed memory deficits when assayed with radial arm maze tasks. However, chronic traumatic stress did not induce anxiety, locomotor hyperactivity or anhedonia. In the hippocampus of stressed mice interleukin-1β protein expression was increased along with decreased corticotropin releasing hormone (CRH) gene expression. Furthermore, there was a reduction in acetylcholine levels in the hippocampus of stressed mice. There were no changes in brain derived neurotrophic factor (BDNF) or nerve growth factor (NGF) levels in the hippocampus of stressed mice. Gene expression of immediate early genes (Zif268, Arc, C-Fos) as well as glucocorticoid and mineralocorticoid receptors were also not affected by chronic stress. These data demonstrate that chronic traumatic stress followed by a recovery period might lead to development of resilience resulting in the development of selected, most vulnerable behavioral alterations and molecular changes in the hippocampus.

Inhibitor of lysyl oxidase improves cardiac function and the collagen/MMP profile in response to volume overload.

El Hajj, Elia C; El Hajj, Milad C; Ninh, Van K; Gardner, Jason D

2018-05-18

The cardiac extracellular matrix is a complex architectural network that serves many functions including providing structural and biochemical support to surrounding cells, and regulating intercellular signaling pathways. Cardiac function is directly affected by extracellular matrix (ECM) composition, and alterations of the ECM contribute to progression of heart failure. Initially, collagen deposition is an adaptive response that aims to preserve tissue integrity and maintain normal ventricular function. However, the synergistic effects of the pro-inflammatory and pro-fibrotic responses induce a vicious cycle which causes excess activation of myofibroblasts, significantly increasing collagen deposition and accumulation in the matrix. Further, excess synthesis and activation of the enzyme lysyl oxidase (LOX) during disease increases collagen cross-linking, which significantly increases collagen resistance to degradation by matrix metalloproteinases (MMPs). In this study, the aortocaval fistula model of volume overload (VO) was used to determine whether LOX inhibition could prevent adverse changes in the ECM and subsequent cardiac dysfunction. The major findings from this study are that LOX inhibition: (a) prevented VO-induced increases in LV wall stress, (b) partially attenuated VO-induced ventricular hypertrophy, (c) completely blocked the increases in fibrotic proteins, including collagens, MMPs, and their tissue inhibitors (TIMPs), and (d) prevented the VO-induced decline in cardiac function. It remains unclear whether a direct interaction between LOX and MMPs exists; however our studies suggest a potential link between the two since LOX inhibition completely attenuated the VO-induced increases in MMPs. Overall, our studies demonstrate key cardioprotective effects of LOX inhibition against adverse cardiac remodeling due to chronic VO.

To determine the prevalence and type of the clinical safety problems contained in the complaints made by patients and users in Primary Care. An observational, descriptive, cross-sectional study was conducted by analysing both the complaint forms and the responses given to them in the period of one year. At least 4.6% of all claims analysed in this study contained clinical safety problems. The family physician is the professional who received the majority of the complaints (53.6%), and the main reason was the problems related to diagnosis (43%), mainly the delay in diagnosis. Other variables analysed were the severity of adverse events experienced by patients (in 68% of cases the patient suffered some harm), the subsequent impact on patient care, which was affected in 39% of cases (7% of cases even requiring hospital admission), and the level of preventability of adverse events (96% avoidable) described in the claims. Finally the type of response issued to each complaint was analysed, being purely bureaucratic in 64% of all cases. Complaints are a valuable source of information about the deficiencies identified by patients and healthcare users. There is considerable scope for improvement in the analysis and management of claims in general, and those containing clinical safety issues in particular. To date, in our area, there is a lack of appropriate procedures for processing these claims. Likewise, we believe that other pathways or channels should be opened to enable communication by patients and healthcare users. Copyright © 2015 SECA. Published by Elsevier Espana.

The aim of the study was to explore the association of dementia with in-hospital death in acutely ill medical patients. Thirty-four internal medicine and 4 geriatric wards in Italy participated in the Registro Politerapie SIMI-REPOSI-study during 2008. One thousand three hundred and thirty two in-patients aged 65 years or older were enrolled. Logistic regression models were used to evaluate the association of dementia with in-hospital death. Socio-demographic characteristics, morbidity (single diseases and the Charlson Index), number of drugs, and adverse clinical events during hospitalization were considered as potential confounders. One hundred and seventeen participants were diagnosed as being affected by dementia. Patients with dementia were more likely to be women, older, to have cerebrovascular diseases, pneumonia, and a higher number of adverse clinical events during hospitalization. The percentage of patients affected by dementia who died during hospitalization was higher than that of patients without dementia (9.4 versus 4.9%). After multiadjustment, the diagnosis of dementia was associated with in-hospital death (OR = 2.1; 95% CI = 1.0-4.5). Having dementia and at least one adverse clinical event during hospitalization showed an additive effect on in-hospital mortality (OR = 20.7; 95% CI = 6.9-61.9). Acutely ill elderly patients affected by dementia are more likely to die shortly after hospital admission. Having dementia and adverse clinical events during hospital stay increases the risk of death. Copyright © 2010 John Wiley & Sons, Ltd.

Negative affect and a tendency to "jump to conclusions" (JTC) are associated with paranoia. So far, only negative affect has been examined as a precursor of subsequent paranoia in daily life using experience sampling (ESM). We addressed this research gap and used ESM to test whether JTC fluctuates in daily life, whether it predicts subsequent paranoia, and whether it mediates the effect of negative affect on paranoia. Thirty-five participants with schizophrenia spectrum disorders repeatedly self-reported negative affect, JTC, and paranoia via online questionnaires on two consecutive days. We measured JTC with a paradigm consisting of ambiguous written scenarios. Multilevel linear models were conducted. Most participants showed JTC consistently on two days rather than only on one day. When time was used as a predictor of JTC, significant slope variance indicated that for a subgroup of participants JTC fluctuated over time. For 48% of participants, these fluctuations equaled changes of approximately ±1 point on the four-point JTC scale within one day. There was no mediation. However, negative affect and JTC both significantly predicted subsequent paranoia. The ESM assessment period was short and encompassed few assessments (8 in total). Our findings indicate that JTC is both stable (regarding its mere occurrence) and fluctuating simultaneously (regarding its magnitude). Although JTC was not a mediator linking negative affect and paranoia, it did predict paranoia. Further ESM studies on JTC are needed to confirm our findings in longer assessment periods and with other JTC paradigms. Copyright © 2016 Elsevier Ltd. All rights reserved.

Corrosion in grid-scale energy storage devices adversely affects service lifetime and thus has a significant economic impact on their deployment. In this work, we investigate the corrosion of steel and stainless steels (SSs) as positive current collectors in the Li||Sb-Pb liquid metal battery. The erosion and formation of new phases on low-carbon steel, SS301, and SS430 were evaluated both in static conditions and under cell operating conditions. The cell performance is not adversely affected by the dissolution of iron or chromium but rather nickel. Furthermore, the in situ formation of a Fe-Cr-Sb layer helps mitigate the recession of SS430.

Diagnosis of potential stressors adversely affecting benthic ...

EPA Pesticide Factsheets

Greenwich Bay is an urbanized embayment of Narragansett Bay potentially impacted by multiple stressors. The present study identified the important stressors affecting Greenwich Bay benthic fauna. First, existing data and information were used to confirm that the waterbody was impaired. Second, the presence of source, stressor, and effect were established. Then linkages between source, stressor, and effect were developed. This allows identification of probable stressors adversely affecting the waterbody. Three pollutant categories were assessed: chemicals, nutrients, and suspended sediments. This weight of evidence approach indicated that Greenwich Bay was primarily impacted by eutrophication-related stressors. The sediments of Greenwich Bay were carbon enriched and low dissolved oxygen concentrations were commonly seen, especially in the western portions of Greenwich Bay. The benthic community was depauperate, as would be expected under oxygen stress. Although our analysis indicated that contaminant loads in Greenwich Bay were at concentrations where adverse effects might be expected, no toxicity was observed, as a result of high levels of organic carbon in these sediments reducing contaminant bioavailability. Our analysis also indicated that suspended sediment impacts were likely nonexistent for much of the Bay. This analysis demonstrates that the diagnostic procedure was useful to organize and assess the potential stressors impacting the ecological well-being

Do the frequencies of adverse events increase, decrease, or stay the same with long-term use of statins?

Statins are widely used for their cholesterol-lowering properties and proven reduction of cardiovascular disease risk. Many patients take statins as long-term treatment for a variety of conditions without a clear-cut understanding of how treatment duration affects the frequency of adverse effects. We aimed to evaluate whether the frequencies of documented adverse events increase, decrease, or remain unchanged with long-term statin use. We reviewed the established literature to define the currently known adverse effects of statin therapy, including myopathy, central nervous system effects, and the appearance of diabetes, and the frequency of these events with long-term medication use. The frequency of adverse effects associated with long-term statin therapy appears to be low. Many patients who develop side effects from statin therapy do so relatively soon after initiation of therapy, so the frequency of side effects from statin therapy when expressed as a percentage of current users decreases over time. Nevertheless, patients may develop side effects such as muscle pain and weakness years after starting statin therapy; however, the absolute number of patients affected by statin myopathy increases with treatment duration. Also, clinical trials of statin therapy rarely exceed 5 years, so it is impossible to determine with certainty the frequency of long-term side effects with these drugs.

It remains unclear whether brain structural abnormalities observed before the onset of psychosis are specific to schizophrenia or are common to all psychotic disorders. This study aimed to measure regional gray matter volume prior to the onset of schizophreniform and of affective psychoses. We investigated 102 subjects at ultrahigh risk (UHR) of developing psychosis recruited from the Personal Assessment and Crisis Evaluation Clinic in Melbourne, Australia. Twenty-eight of these subjects developed psychosis subsequent to scanning: 19 schizophrenia, 7 affective psychoses, and 2 other psychoses. We examined regional gray matter volume using 1.5 mm thick, coronal, 1.5 Tesla magnetic resonance imaging and voxel-based morphometry methods of image analysis. Subjects were scanned at presentation and were followed up clinically for a minimum of 12 months, to detect later transition to psychosis. We found that both groups of subjects who subsequently developed psychosis (schizophrenia and affective psychosis) showed reductions in the frontal cortex relative to UHR subjects who did not develop psychosis. The subgroup that subsequently developed schizophrenia also showed smaller volumes in the parietal cortex and, at trend level, in the temporal cortex, whereas those who developed an affective psychosis had significantly smaller subgenual cingulate volumes. These preliminary findings suggest that volumetric abnormalities in UHR individuals developing schizophrenia vs affective psychoses comprise a combination of features that predate both disorders and others that may be specific to the nature of the subsequent disorder.

Adverse childhood experiences (ACEs) impact health across the life course. The purpose of this study was to identify caregiver ACEs, current adversity, and resilience in families seeking care in pediatric acute care settings. Study aims included identifying demographic characteristics, current adversities, and resilience measures associated with caregiver ACEs ≥4. A cross-sectional survey study design was used and a convenience sample (n = 470) recruited at emergency and urgent care settings of a large Midwest pediatric hospital system. Measures were self-reported. The original 10-item ACEs questionnaire measured caregiver past adversity. Current adversity was measured using the 10-item IHELP. The six-item Brief Resiliency Scale measured resilience, and WHO-5 Well-Being Index was used to measure depressive affect. Compared to participants with ACEs score of 0-3 participants with ACEs ≥4 were more likely to have multiple current adversities, increased risk of depression, and lower resilience. Caregivers using pediatric acute care settings carry a high burden of ACEs and current adversities. Caregiver ACEs are associated with current child experiences of adversity. Caregivers socioeconomic status and education level may not be an accurate indicator of a family's risks or needs. Pediatric acute care settings offer opportunities to access, intervene, and prevent childhood adversity. © 2016 Wiley Periodicals, Inc.

We evaluate the safety and feasibility of a critical care pathway protocol in which patients with acute chest pain who are low risk for coronary artery disease and short-term adverse cardiac outcomes receive outpatient stress testing within 72 hours of an emergency department (ED) visit. We performed an observational study of an ED-based chest pain critical pathway in an urban, community hospital in 979 consecutive patients. Patients enrolled in the protocol were observed in the ED before receiving 72-hour outpatient stress testing. The pathway was primarily analyzed for rates of death or myocardial infarction in the 6 months after ED discharge and outpatient stress testing. Secondary outcome measures included need for coronary intervention at initial stress testing and within 6 months after discharge, subsequent ED visits for chest pain, and subsequent hospitalization. Of 871 stress-tested patients aged 40 years or older, who had low risk for coronary artery disease and short-term adverse cardiac events, and had 6-month follow-up, 18 (2%) required coronary intervention, 1 (0.1%) had a myocardial infarction within 1 month, 2 (0.2%) had a myocardial infarction within 6 months, 6 (0.7%) had normal stress test results after discharge but required cardiac catheterization within 6 months, and 5 (0.6%) returned to the ED within 6 months for ongoing chest pain. Hospital admission rates decreased significantly from 31.2% to 26.1% after initiation of the protocol (P<.001). For patients with chest pain and low risk for short-term cardiac events, outpatient stress testing is feasible, safe, and associated with decreased hospital admission rates. With an evidence-based protocol, physicians efficiently identify patients at low risk for clinically significant coronary artery disease and short-term adverse cardiac outcomes.

Mobile phone interventions have been advocated for tuberculosis care, but little is known about access of target populations to mobile phones. We studied mobile phone access amongst patients with tuberculosis, focusing on vulnerable patients and patients who later had adverse treatment outcomes. In a prospective cohort study in Callao, Peru, we recruited and interviewed 2,584 patients with tuberculosis between 2007-2013 and followed them until 2016 for adverse treatment outcomes using national treatment registers. Subsequently, we recruited a further 622 patients between 2016-2017. Data were analysed using logistic regression and by calculating relative risks (RR). Between 2007-2013, the proportion of the general population of Peru without mobile phone access averaged 7.8% but for patients with tuberculosis was 18% (p<0.001). Patients without access were more likely to hold a lower socioeconomic position, suffer from food insecurity and be older than 50 years (all p<0.01). Compared to patients with mobile phone access, patients without access at recruitment were more likely to subsequently have incomplete treatment (20% versus 13%, RR=1.5; p=0.001) or an adverse treatment outcome (29% versus 23% RR=1.3; p=0.006). Between 2016 and 2017, the proportion of patients without access dropped to 8.9% overall, but remained the same (18%) as in 2012 among the poorest third. Access to mobile phones among patients with tuberculosis is insufficient, and rarest in patients who are poorer and later have adverse treatment outcomes. Thus, mobile phone interventions to improve tuberculosis care may be least accessed by the priority populations for whom they are intended. Such interventions should ensure access to mobile phones to enhance equity. This article is protected by copyright. All rights reserved. This article is protected by copyright. All rights reserved.

Restrictive covenants in physician contracts: an American Society of Colon and Rectal Surgeons' Survey.

2011-04-01

A restrictive covenant (RC) may be a cause for concern among any physician entering into a contractual agreement. This survey of graduates of colorectal surgery residency training programs aimed to determine whether this was an important issue among the members of this group. An electronic survey generated by the Young Surgeons' Committee of the American Society of Colon and Rectal Surgeons (ASCRS) regarding employment contracts was sent to all graduates of colorectal surgery residency training programs from the preceding 10-year period. The survey included 5 questions (including an open-ended question for those who experienced an adverse effect when a RC was enforced), followed by queries designed to generate demographic data. This was an anonymous survey with an option to enter the name of the respondent. There were a total of 157 responses to the survey of 630 sent (25%). Of the 132 respondents to the survey who had signed a contract, 67 respondents (53%) had signed a contract that contained a RC, and 24 of these 67 respondents (35%) subsequently changed employment. The RC was enforced for 15 of these 24 respondents (63%) resulting in an adverse effect for 8 of the 15 (53%). The age range of those adversely effected was 32 to 41 years (mean, 36.3 y), all but 1 had been in private practice (86%) from 1 to 6 years (mean, 2.9 y). Most were men (71%) and all were married. The majority of survey respondents signed an employment agreement that contained a RC. Overall, 35% of the respondents subsequently changed employment and the RC was enforced in most cases (63%), often with an adverse effect on career and life (53%). ASCRS members should consider the potentially devastating consequences of signing a contract that contains a RC, especially if they would be averse to changing geographic location should they face a change in employment.

Selective exposure to information: how different modes of decision making affect subsequent confirmatory information processing.

PubMed

Fischer, Peter; Fischer, Julia; Weisweiler, Silke; Frey, Dieter

2010-12-01

We investigated whether different modes of decision making (deliberate, intuitive, distracted) affect subsequent confirmatory processing of decision-consistent and inconsistent information. Participants showed higher levels of confirmatory information processing when they made a deliberate or an intuitive decision versus a decision under distraction (Studies 1 and 2). As soon as participants have a cognitive (i.e., deliberate cognitive analysis) or affective (i.e., intuitive and gut feeling) reason for their decision, the subjective confidence in the validity of their decision increases, which results in increased levels of confirmatory information processing (Study 2). In contrast, when participants are distracted during decision making, they are less certain about the validity of their decision and thus are subsequently more balanced in the processing of decision-relevant information.

Status of adolescent pelvic inflammatory disease management in the United States.

PubMed

Trent, Maria

2013-10-01

Pelvic inflammatory disease (PID) is a common and serious reproductive health disorder and disease rates remain unacceptably high among adolescent girls and young adult women in the United States. Despite data demonstrating that women experience major adverse health outcomes after PID, national recommendations for management of adolescents have become increasingly less cautious in an era of cost-containment. In this review, we take an alternative look at published data on adolescents with PID to frame the next steps for optimizing management for this vulnerable population. Several findings emerge from review of the literature. First, there is limited evidence to guide the best practice strategies for adolescents with PID due to low enrolment of early and middle adolescents in national trials. Second, adolescents and adult women in the United States receive suboptimal treatment regimens per Centers for Disease Control and Prevention (CDC) standards. Third, available evidence suggests that adolescents are at an increased risk for poor adherence to CDC recommendations for self-care, reacquisition of sexually transmitted infections (STIs) and PID, and subsequent adverse reproductive health outcomes. Efforts to develop and integrate adolescent-focused, evidence-based strategies for PID management and prevention of subsequent STIs and recurrent PID are warranted.

This study used experience sampling methodology to examine (i) associations of a range of childhood adversities with psychosis symptom domains in daily life; (ii) whether associations of abuse and neglect with symptoms are consistent across self-report and interview methods of trauma assessment; and (iii) the role of different adversities in moderating affective, psychotic-like, and paranoid reactivity to situational and social stressors. Method A total of 206 nonclinical young adults were administered self-report and interview measures to assess childhood abuse, neglect, bullying, losses, and general traumatic events. Participants received personal digital assistants that signaled them randomly eight times daily for one week to complete questionnaires about current experiences, including symptoms, affect, and stress. Results Self-reported and interview-based abuse and neglect were associated with psychotic-like and paranoid symptoms, whereas only self-reported neglect was associated with negative-like symptoms. Bullying was associated with psychotic-like symptoms. Losses and general traumatic events were not directly associated with any of the symptom domains. All the childhood adversities were associated with stress reactivity in daily life. Interpersonal adversities (abuse, neglect, bullying, and losses) moderated psychotic-like and/or paranoid reactivity to situational and social stressors, whereas general traumatic events moderated psychotic-like reactivity to situational stress. Also, different interpersonal adversities exacerbated psychotic-like and/or paranoid symptoms in response to distinct social stressors. Discussion The present study provides a unique examination of how childhood adversities impact the expression of spectrum symptoms in the real world and lends support to the notion that stress reactivity is a mechanism implicated in the experience of reality distortion in individuals exposed to childhood trauma. Investigating the interplay between childhood experience and current context is relevant for uncovering potential pathways to the extended psychosis phenotype. PMID:27082442

Understanding the link between adverse childhood experiences (ACEs) and sexual victimization (SV) in adulthood may provide important information about the level of risk for adult SV and sexual re-victimization among childhood sexual abuse (CSA) survivors. In the present paper, we explore the relationship between ACEs, including CSA, and SV in adulthood. Data from the CDC-Kaiser ACE Study were used to examine the effect of experiences of early adversity on adult SV. Adult HMO members (n=7,272) undergoing a routine health exam provided detailed information about ACEs that occurred at age 18 or younger and their experiences of SV in adulthood. Analyses revealed that as ACE score increased, so did risk of experiencing SV in adulthood. Each of the ACE variables was significantly associated with adult SV, with CSA being the strongest predictor of adult SV. In addition, for those who reported CSA, there was a cumulative increase in adult SV risk with each additional ACE experienced. As such, early adversity is a risk factor for adult SV. In particular, CSA is a significant risk factor for sexual re-victimization in adulthood, and additional early adversities experienced by CSA survivors may heighten adult SV risk above and beyond the risk associated with CSA alone. Given the interconnectedness among various experiences of early adversity, adult SV prevention actions must consider how other violence-related and non-violence-related traumatic experiences may exacerbate the risk conferred by CSA on subsequent victimization.

Young children in foster care are exposed to high levels of stress. These experiences place foster children at risk for poor social, academic, and mental heath outcomes. The role of adverse events in stimulating neurobiological stress responses presumably plays a role in shaping neural systems that contribute to these problems. Systematic and developmentally well-timed interventions might have the potential to change developmental trajectories and promote resilience. Moreover, understanding how specific dimensions of early adversity affect underlying stress response systems and how alterations in these systems are related to later psychosocial outcomes might facilitate more precise and targeted interventions. Data are drawn from two ongoing randomized trials involving foster infants/toddlers and preschoolers. Consistent with prior animal models of early adversity, these studies have shown that early adversity-particularly neglect, younger age at first foster placement, and higher number of placements-is associated with altered hypothalamic-pituitary-adrenal (HPA) axis function. The interventions under investigation have produced evidence that it is possible to impact many areas that have been negatively affected by early stress, including HPA axis activity, behavior, and attachment to caregivers.

The authors sought to determine if the availability of an after-hours on-call emergency physician by telephone for consultation to the staff at a county jail would safely reduce ambulance emergency department (ED) transport of inmates in the community. The authors conducted a prospective comparison study during the first ten months of an emergency physician on-call program for the county jail in which prospective data were collected on all consultations, including reason for call and disposition (ambulance, deputy, or no ED transport of inmate). They compared this time with a similar period a year before the program in terms of total ambulance transports from the jail. They also reviewed all hospital and jail medical records to assess for any adverse consequences within one month, or subsequent ambulance transport within 24 hours as a result of inmate care after the consultation call. Total after-hours ambulance transports from the jail decreased significantly from 30.3 transports/month (95% confidence interval [CI], 21.0-39.6) to 9.1 transports/month (95% CI, 4.1-14.0) (p < 0.05). The most common reasons for consultation calls were chest pain (16%), trauma (15%), and abnormal laboratory or radiology results (14%). Of all calls, only 30% resulted in ambulance transport to the ED. On review of records, no adverse outcome or subsequent ambulance transport was identified. The initiation of an on-call emergency physician program for after-hours consultation to jail nursing and law enforcement staff safely reduced ambulance transports from a county jail with no adverse outcomes identified.

Objective To compare effects of adverse childhood experiences and adverse adult experiences on recovery from serious mental illnesses. Methods As part of a mixed-methods study of recovery from serious mental illnesses, we interviewed and administered questionnaires to 177 members of a not-for-profit health plan over a two-year period. Participants had a diagnosis of bipolar disorder, affective psychosis, schizophrenia or schizoaffective disorder. Data for analyses came from standardized self-reported measures; outcomes included recovery, functioning, quality of life, and psychiatric symptoms. Adverse events in childhood and adulthood were evaluated as predictors. Results Child and adult exposures to adverse experiences were high, at 91% and 82% respectively. Cumulative lifetime exposure to adverse experiences (childhood plus adult experiences) was 94%. In linear regression analyses, adverse adult experiences were more important predictors of outcomes than adverse childhood experiences. Adult experiences were associated with lower recovery scores, quality of life, mental and physical functioning, social functioning, and greater psychiatric symptoms. Emotional neglect in adulthood was associated with lower recovery scores. Conclusions and Implications for Practice Early and repeated exposure to adverse events was common in this sample of people with serious mental illnesses. Adverse adult experiences were stronger predictors of worse functioning and lower recovery levels than were childhood experiences. Focusing clinical attention on adult experiences of adverse or traumatic events may result in greater benefit than focusing on childhood experiences alone. PMID:26053533

The aim of this study was to describe the tolerability of high-dose baclofen taken by patients with alcohol disorders during their first year of treatment. The medical records of all patients prescribed baclofen by one general practitioner were examined and all patients who could be contacted were retrospectively interviewed about adverse effects. Of the 146 eligible patients, 116 (79%) could be interviewed. Ninety (78%) reported at least one adverse effect (mean number per patient: 2.8 ± 2.7). The mean dosage of baclofen at the onset of the first adverse effect was 83 ± 57 mg/day. The most frequent group of adverse effects involved disruption of the wake-sleep cycle and affected 73 patients (63%). Persistent adverse effects occurred in 62 patients (53%). Eight patients (7%) had adverse effects that led them to stop taking baclofen. Their dosages were <90 mg/day at that time. Alertness disorders and depression were the adverse effects that most frequently led to stopping baclofen. Bouts of somnolence and hypomanic episodes were the most potentially dangerous adverse effects. Women reported significantly more adverse effects than men. High-dose baclofen exposes patients with alcohol disorders to many adverse effects. Generally persistent, some adverse effects appear at low doses and may be dangerous. © The Author 2015.

Ruminative Self-Focus and Negative Affect

PubMed Central

Moberly, Nicholas J.; Watkins, Edward R.

The authors conducted an experience sampling study to investigate the relationship between momentary ruminative self-focus and negative affect. Ninety-three adults recorded these variables at quasi-random intervals 8 times daily for 1 week. Scores on questionnaire measures of dispositional rumination were associated with mean levels of momentary ruminative self-focus over the experience sampling week. Concurrently, momentary ruminative self-focus was positively associated with negative affect. Cross-lagged analyses revealed that whereas ruminative self-focus predicted negative affect at a subsequent occasion, negative affect also predicted ruminative self-focus at a subsequent occasion. Decomposition of the dispositional rumination measure suggested that brooding, but not reflective pondering, was associated with higher mean levels of negative affect. Though broadly consistent with Nolen-Hoeksema's (1991) response styles theory, these results suggest that a reciprocal relationship exists between ruminative self-focus and negative affect.

Birth outcomes may influence subsequent susceptibility to chronic diseases. With the increased number of women who continue to work during pregnancy, occupational stress has been hypothesized to be a potential contributor to adverse reproductive health outcomes. The Job Demand and Control model has been primarily used in investigating associations between work-related stress and outcomes such as preterm delivery, low birth weight, and spontaneous abortion. A literature review of occupational factors that have been associated with adverse reproductive outcomes was conducted. In studies assessing preterm delivery and low birth weight, some evidence has suggested a modest association with work-related stress but has not been conclusive. In the literature on psychosocial characteristics of work and spontaneous abortion, job strain alone was often not associated with adverse outcomes. However the presence of other risk factors resulted in a synergistic effect which strengthened the odds of an adverse outcome. Future studies should use a prospective design with a large study sample, in which work-related stress exposure data are collected before or in the early stages of the pregnancy. In addition, future research should measure psychosocial characteristics of work both objectively and subjectively.
