Morales-Ramos, Juan A; Rojas, M Guadalupe

2015-10-01

Crowding conditions of larvae may have a significant impact on commercial production efficiency of some insects, such as Tenebrio molitor L. (Coleoptera: Tenebrionidae). Although larval densities are known to affect developmental time and growth in T. molitor, no reports were found on the effects of crowding on food utilization. The effect of larval density on food utilization efficiency of T. molitor larvae was studied by measuring efficiency of ingested food conversion (ECI), efficiency of digested food conversion (EDC), and mg of larval weight gain per gram of food consumed (LWGpFC) at increasing larval densities (12, 24, 36, 48, 50, 62, 74, and 96 larvae per dm(2)) over four consecutive 3-wk periods. Individual larval weight gain and food consumption were negatively impacted by larval density. Similarly, ECI, ECD, and LWGpFC were negatively impacted by larval density. Larval ageing, measured as four consecutive 3-wk periods, significantly and independently impacted ECI, ECD, and LWGpFC in a negative way. General linear model analysis showed that age had a higher impact than density on food utilization parameters of T. molitor larvae. Larval growth was determined to be responsible for the age effects, as measurements of larval mass density (in grams of larvae per dm(2)) had a significant impact on food utilization parameters across ages and density treatments (in number of larvae per dm(2)). The importance of mass versus numbers per unit of area as measurements of larval density and the implications of negative effects of density on food utilization for insect biomass production are discussed.

Zaleplon appears to be a prime candidate for assisting individuals in obtaining sleep in situations not conducive to rest (i.e., a short period during the day). However, should an early unexpected awakening and return to duty be required, the effect on performance is not known. Zaleplon (10 mg) would negatively affect human performance for some duration, compared with placebo, after a sudden awakening from a short period (1 h) of daytime sleep. There were 16 participants, 8 men and 8 women, who volunteered to participate in this study. The study was conducted using a counterbalanced, double-blind, repeated measures design. At 1 h prior to drug administration, and at each of 7 h postdrug, performance measures (cognition, memory, balance, and strength) and subjective symptom reports were recorded. Zaleplon had a statistically significant (p < 0.05) negative impact on balance through the first 2 h postdose when compared with placebo. In addition, symptoms related to "drowsiness" were statistically more prevalent under zaleplon than under placebo through the first 3 h postdrug. Of the eight measures of cognitive performance, six were significantly negatively impacted in the zaleplon condition through 2 h postdose when compared with placebo, with one remaining significantly degraded through 3 h postdose. Zaleplon also had a significantly negative impact on memory at 1 h and 4 h postdose. Zaleplon (10 mg), when used as a daytime sleep aid, causes drowsiness (and related symptoms) up to 3 h postdose, and may impact task performance, especially more complex tasks, for at least 2-3 h postdose.

Red imported fire ant impacts on wildlife: A decade of research

2004-01-01

The negative impacts of biological invasion are economically and ecologically significant and, while incompletely quantified, they are clearly substantial. Ants (family Formicidae) are an important, although often overlooked, component of many terrestrial ecosystems. Six species of ants are especially striking in their global ability to invade, and their impacts. This paper focuses on the impacts of the most destructive of those species, the red imported fire ant (Solenopsis invicta), and focuses on impacts on native vertebrates. Red imported fire ants often become the dominant ant species in infested areas outside of their native range due to their aggressive foraging behavior, high reproductive capability and lack of predators and/or other strong competitors. The evidence suggests that mammals, birds and herpetofauna are vulnerable to negative impacts from fire ants, and some species are more likely to experience negative population-level impacts than other species. Assessing the ecological impacts of fire ants on wild animal populations is logistically difficult, and very few studies have combined replicated experimental manipulation with adequate spatial (>10 ha) and temporal (>1 y) scale. Thus, most studies have been observational, opportunistic, small-scale or 'natural' experiments. However, significant research, including an increase in experimental and mechanistic investigations, has occurred during the past decade, and this has led to information that can lead to better management of potentially affected species.

Introduction and purpose Wearing orthodontic appliances may negatively affect a patient’s oral health-related quality of life (OHRQoL) physiologically, psychologically, and socially. Few studies have assessed the effect of palatal expanders on OHRQoL. The aim of this study was to evaluate the impact of palatal expanders on OHRQoL and to compare it with that of fixed orthodontic appliances. Materials and methods All adolescent and adult orthodontic patients who were undergoing treatment with fixed appliances or palatal expanders between July 2015 and January 2016 in King Abdulaziz University Orthodontc Dental Clinics, were recruited (n=399). The OHRQoL of each participant was assessed using the shortened Arabic version of the Oral Health Impact Profile-14 questionnaire. OHRQoL was compared between users of fixed appliances and users of palatal expanders; it was also compared after stratifying the patients by gender. Chi-squared and Fisher’s exact tests were used, as indicated. Results Palatal expanders had significantly greater negative effects on chewing ability (P≤0.01) and pronunciation (P=0.048). However, fixed orthodontic appliances had significantly greater negative impacts on mouth aching (P=0.003), difficulty in relaxing (P=0.01), irritability (P=0.001), and embarrassment (P≤0.01). Conclusion Palatal expanders had a significantly greater negative impact on some aspects of OHRQoL when compared with fixed orthodontic appliances in adolescents and young adults. PMID:28408807

Newman, Louise

2013-01-01

Asylum seekers represent a highly traumatized group with experiences of systematic oppression, loss, displacement, and exposure to violence. Around the world many are viewed with distrust and anxiety. The Australian response to asylum seekers is one that has used prolonged detention with significant negative impact on mental health. This has prompted much social debate and the involvement of clinicians and researchers in advocating for the human rights of asylum seekers. This article reviews the impact of mandatory prolonged detention on the mental health of asylum seekers and the significance of this for recovery and adaption. It concludes that the mandatory detention of high-risk and oppressed groups compounds trauma, with a potential long-term negative impact on mental health.

To investigate the impact of wearing a fixed orthodontic appliance on oral health-related quality of life (OHRQoL) among adolescents. A case-control study (1 ∶ 2) was carried out with a population-based randomized sample of 327 adolescents aged 11 to 14 years enrolled at public and private schools in the City of Brumadinho, southeast of Brazil. The case group (n  =  109) was made up of adolescents with a high negative impact on OHRQoL, and the control group (n  =  218) was made up of adolescents with a low negative impact. The outcome variable was the impact on OHRQoL measured by the Brazilian version of the Child Perceptions Questionnaire (CPQ 11-14) - Impact Short Form (ISF:16). The main independent variable was wearing fixed orthodontic appliances. Malocclusion and the type of school were identified as possible confounding variables. Bivariate and multiple conditional logistic regressions were employed in the statistical analysis. A multiple conditional logistic regression model demonstrated that adolescents wearing fixed orthodontic appliances had a 4.88-fold greater chance of presenting high negative impact on OHRQoL (95% CI: 2.93-8.13; P < .001) than those who did not wear fixed orthodontic appliances. A bivariate conditional logistic regression demonstrated that malocclusion was significantly associated with OHRQoL (P  =  .017), whereas no statistically significant association was found between the type of school and OHRQoL (P  =  .108). Adolescents who wore fixed orthodontic appliances had a greater chance of reporting a negative impact on OHRQoL than those who did not wear such appliances.

To examine the factors that impact career satisfaction for various surgical specialties. An acute shortage of surgeons is anticipated in the future. Career dissatisfaction can make this already difficult situation worse. It is important to understand and address factors that influence career satisfaction of surgeons to prolong tenure of existing surgeons and understand anticipated needs of future surgeons. The Center for Studying Health System Change 2008 Health Tracking Physician Survey data were used in this study. Regression analysis was done to examine the impact of various practice-related factors, compensation-related factors, practice location, extent of minority patient, and various demographics on career satisfaction of various surgical specialties (n = 762). Among practice related factors, although threat of malpractice had a significant negative impact on career satisfaction, ability to provide quality care to patients and time with patients had a significant positive impact on career satisfaction of surgical specialists. Among compensation related factors, income and financial incentives to expand services had a significant positive impact on career satisfaction. Among practice location factors, those who primarily worked in medical schools were significantly more satisfied with their careers than others. Among minority factors, those treating a large proportion of Hispanic patients were significantly less likely to be satisfied with their careers. Ability to provide quality care, time with patients, income, and financial incentives had a significant positive impact on career satisfaction. Similarly, threat of malpractice and high proportion of Hispanic patients had a negative impact on career satisfaction.

Low self-esteem has been identified as a maintaining factor in Cognitive Behavioural models of eating disorders and links have been identified between early memories, negative core beliefs and mental imagery. This study explored the impact of positive and negative self-imagery on aspects of the working self (implicit and explicit self-esteem, self-concept clarity and self-discrepancy) and affect. Participants with high levels of eating disorder cognitions completed measures of explicit self-esteem, self-concept clarity, self-discrepancy and affect prior to completing a positive or negative self-imagery retrieval task. Baseline measures were then repeated and a measure of implicit self-esteem completed. Positive self-imagery retrieval led to a significant increase in positive explicit self-esteem and a significant reduction in negative explicit self-esteem and actual-ideal self-discrepancies. Negative self-imagery retrieval led to a significant increase in negative explicit self-esteem and actual-ideal self-discrepancies and a significant reduction in positive explicit self-esteem. Levels of implicit self-esteem did not differ between the two groups post imagery manipulation. Retrieving a positive self-image also led to an improvement in state self-concept clarity; however, no effect was found for the negative self-imagery intervention. Holding a positive self-image in mind led to an increase in state positive affect and a reduction in state negative affect. The opposite was found for negative self-image retrieval. The study did not measure implicit self-esteem at baseline. Imagery techniques that involve the retrieval of a positive self-image may help to improve aspects of the working-self and affect in those with eating difficulties. Copyright © 2018 Elsevier Ltd.

The aim of the present study is to find the neural features of the impact of induced negative emotion on brand extension. Facing three sequential stimuli in triples consisted of negative emotion pictures (stimulus 1), beverage brand names (stimulus 2), and product names (stimulus 3) in other categories, 20 participants were asked to indicate the suitability of extending the brand in stimulus 2 to the product category in stimulus 3. The stimulus triples were divided into six conditions depending on the emotion (neutral and negative) and the extension product category in stimulus 3: beverage, clothing, and the household appliance. A negative component reflecting conflict, N2, was recorded for each condition on the subjects' scalp. The induced negative emotion elicited significantly larger amplitude of N2 than did the induced neutral emotion in the moderate extension type (extending to the clothing product), whereas no significant difference was observed in any of the other two extension types. The findings indicate that the induced negative emotion has a specific negative impact on moderate brand extension, and the amplitude of N2 can be viewed as a reference measure reflecting such effect.

Agricultural growth, the status of women, and fertility.

PubMed

Whittington, L A; Stapleton, D C

1995-08-01

This study tests the hypothesis that fertility is affected differently by economic growth depending upon the specific sector (agriculture, manufacturing, heavy industry, and services) where growth occurred. The hypothesis is that fertility responses are not identical across sectors. The sample includes 51 World Bank member countries in varying stages of development. The econometric model pertains to 1965-88 and the percentage change in the total fertility rate (TFR). During the study period the average TFR declined by over 22%, but the extent of change varied by country and included, for instance, countries such as Ethiopia that experienced fertility increases from 5.8 to 6.5. Hong Kong's TFR declined by 66% from 4.7 to 1.6. Analysis included measures of changes in gross domestic product (GDP) for each of the four sectors and change in real per capita exports in agricultural commodities, resources, and manufactured products. Changes in educational status and changes in infant mortality were also included in some models. There were mixed results for the impact of total GDP. Sectoral analysis shows a positive, small significant impact on TFR from changes in the GDP per capita in agriculture (domestic and export products), and a negative, small significant impact from manufacturing growth. Heavy industry and services produced insignificant impact. In the model with only domestic consumption, results show a stronger coefficient and continued significance for agricultural productivity, agricultural exports, and manufacturing changes per capita. Manufacturing exports produced a negative, insignificant impact. The null hypothesis is rejected only in models comparing aggregate GDP in agriculture and manufacturing industries plus control variables (excluding heavy industry and services). Only secondary education was a negative, significant determinant of fertility. Infant mortality was insignificant when sectoral growth and education were included in the model. The evidence supports the thesis that growth depending on the sector leads to fertility decline, and economic growth has a negative effect on fertility if employment opportunities for women are improved.

Aggression and violence in healthcare and its impact on nursing students: A narrative review of the literature.

PubMed

Hopkins, Martin; Fetherston, Catherine M; Morrison, Paul

2018-03-01

Aggression and violence is a significant social problem in many countries and an increasing problem in healthcare settings in which nurses are particularly vulnerable. The literature suggests that aggression and violence has a significant negative impact upon nurses and potentially upon nursing students and can result in these staff members experiencing stress as a direct result of these adverse events. The literature suggests that there is confusion over what constitutes aggression and violence in the workplace and therefore a true lack of understanding of the scale of the problem relating to nursing students. This review proposes that nursing students are indeed at significant risk of aggression and violence in the clinical setting which has the potential to significantly impact their role as a novice carer. Furthermore, aggression and violence can manifest negative stress responses in individuals, therefore, the potential for nursing students to cope with stressful situations shall be presented.

Terrill, Alexandra L; Molton, Ivan R

2018-03-09

Middle-age may be a challenging time for people with physical disabilities as life demands, secondary symptoms such as fatigue, and risk for depression increase, yet little is known about types, levels, and impact of life stressors in individuals aging with disability. Our aims were to describe aging- and disability-associated life stressors, explore gender differences, and evaluate effects of resilience on adjustment to these stressors. Longitudinal data analysis of self-report surveys completed by 541 middle-aged community-dwelling participants with long-term physical disability from baseline to 5-year follow-up. 97% of participants endorsed one or more stressful life events (M = 8.2, SD = 4.9), all of whom endorsed at least one life stressor with a negative impact. Reporting more life stressors and having lower resilience were significantly associated with developing more depressive symptoms. Interaction analyses indicated that women developed more depressive symptoms as negative impact increased than men. Findings suggest that middle-aged individuals with physical disability experience a range of life stressors, many with negative impact. Women are at higher risk of depressive symptoms than men. Resilience may buffer against negative impact of life stressors on development of depressive symptoms. Targeted intervention to increase resilience, especially in women, may decrease risk of depression in persons aging with disability. Implications for Rehabilitation Middle-age adults living with physical disability experience a number of aging- and disability-associated stressors that can have a negative impact and contribute to depression. Women aging with disability who experience more negative impact from life stressors may be more vulnerable to developing depression. Providing interventions that enhance resilience when faced with life stressors could prevent development of depression.

Potential negative effects of earthworm prey on damage to turfgrass by omnivorous mole crickets (Orthoptera: Gryllotalpidae).

PubMed

Xu, Yao; Held, David W; Hu, Xing Ping

2012-10-01

The severity of damage to host plants by omnivorous pests can vary according to the availability of plant and animal prey. Two omnivorous mole crickets, Scapteriscus vicinus Scudder and S. borellii Giglio-Tos, were used to determine if the availability of prey influences damage to hybrid bermudagrass by adult mole crickets. Experiments were conducted in arenas with either grass alone (control), grass plus one mole cricket, grass plus earthworms (Eisenia fetida Savigny), or grass with earthworms and a mole cricket. Root growth variables (e.g., volume, dry weight) after 4 wk and weekly measurements of top growth were compared among the treatments. Surprisingly, bermudagrass infested with either mole cricket species caused no significant reduction in root growth and a minimal reduction on top growth with S. vicinus compared with controls. Survival of earthworms with S. borellii was significantly lower than survival in the earthworm-only treatment suggesting predation. Survival of earthworms with S. vicinus, however, was not different from the earthworm-only treatment. The addition of earthworm prey with mole crickets did not significantly impact bermudagrass root or shoot growth relative to grass with only mole crickets. Despite no negative impacts from earthworms or mole crickets separately, earthworms plus mole crickets negatively impact several root parameters (e.g., length) suggesting an interaction between these two soil-dwelling invertebrates. Increased use of more target-selective insecticides in turfgrass may increase available prey. This work suggests that alternative prey, when present, may result in a negative impact on turfgrass roots from foraging omnivorous mole crickets.

Much recent work extending the field of job characteristics to include positive aspects of work makes the implicit assumption that the absence of negative work characteristics is equivalent to the presence of positive work characteristics. To consider the effect sizes seen at different ends of job characteristic dimensions and to compare the impact of the presence and absence of job characteristics in association with mental health and well-being outcomes. Data from 8755 workers were analysed to compare the impacts of the presence or absence of job characteristics (job demand, extrinsic effort and social support) in associations with both positive (job satisfaction) and negative (work-related stress) outcome measures. Comparable presence and absence impacts were apparent for extrinsic effort in association with work-related stress. However, in the association between job demand and work-related stress, the presence of high levels of job demand had a significantly greater impact than the absence of high levels of job demand; while in the association between social support and job satisfaction, the absence of high levels of social support had a significantly greater impact than the presence of high levels of social support. It is not always appropriate to assume that the absence of negative aspects of the work environment is equivalent to the presence of positive aspects.

Oral health problems have been increasingly recognized as important factors causing a negative impact on daily performance and quality of life. The purpose of this study was to assess the impact of tooth extraction with no replacement, untreated fractured anterior teeth, malocclusion, dental restorations, and orthodontic braces on the quality of life in Nigerian schoolchildren. A total of 197 9- to 17-year-old schoolchildren completed the Oral Health Impact Profile (OHIP) index/questionnaire. Students who had tooth extraction with no replacement and untreated fractured incisors had significantly higher mean OHIP scores for functional limitations, physical pain, psychological discomfort, physical, psychological, and social disabilities, and handicaps (P<.001) when compared to other groups and the control. The mean OHIP scores of students with features of malocclusion were significantly higher for functional limitations, psychological discomfort, and psychological disability compared to the control group (P<.001). Untreated dental problems had some negative impact on the quality of life on the 7 subscales of the OHIP.

The study examined the effect of adult children's disability on parents' physical health in later life and the extent to which parents' symptoms of alcoholism in mid-life moderates the link between children's disability and later life parental health. Analyses are based on data from the Wisconsin Longitudinal Study. The analytic sample included parents of children with developmental disabilities (n = 145) or mental health problems (n = 200) and 2,432 parents of unaffected children. The results showed that the negative health consequences in later life of having a child with a developmental disability were greater for those who showed more symptoms of alcoholism in mid-life. However, symptoms of alcoholism in mid-life did not significantly moderate the impact of an adult child's mental health problems on parents' later life physical health. The findings suggest a potential area where gerontological social workers could intervene, given the negative impact of symptoms of alcoholism on the health of aging parents of children with a disability who may be significantly more susceptible to the negative health impacts of alcohol compared to their younger counterparts.

Positive pleural lavage cytology (PLC) has been reported to have a negative prognostic impact in patients with surgically resected non-small cell lung cancer (NSCLC). However, positive PLC does not upgrade the stage according to the 7th edition of TNM classification for lung cancer. The objectives of this study were to evaluate the prognostic impact of positive PLC in patients with NSCLC and to clarify its contribution to TNM classification. Seven hundred fifty-four patients who underwent surgical resection of NSCLC from January 2007 through December 2013 were retrospectively studied. PLC was performed using 50ml of saline immediately after thoracotomy. Thirty-eight of the 754 patients were positive for PLC (5.1%). The overall survival (OS) of patients with positive PLC was significantly shorter than that of those with negative PLC (P=0.007, log-rank test). In multivariate analyses of OS, positive PLC was a significant independent prognostic factor (hazard ratio=2.21, 95% confidence interval: 1.21-4.04, P=0.009). The OS of patients with positive PLC was significantly shorter than that of those with negative PLC and pT1 (P<0.0001) or negative PLC and pT2 (P<0.0001) and almost overlapped with that of those with negative PLC and pT3 disease (P=0.601). Positive PLC is an independent prognostic factor in patients with resected NSCLC. Based on our analyses, we propose that patients with positive PLC be staged as pT3.

Relict species are an extremely important part of biodiversity and as such studies on the factors that allow their current persistence are required. The aim of this study was to assess the determinants of the distribution and range-wide population performance of the Tertiary relict tree Prunus lusitanica L. This threatened species is confined to Iberia, Northern Morocco and Macaronesia with a fragmented and scattered distribution. Using ecological niche modelling, we calculated the level of range filling across the range and tested its relationship with human impact. We then assessed the relative importance of climatic suitability as obtained through niche modelling, topographic factors and contemporary human impact on range-wide population performance. Results showed that the species occupies only 2.4% of the overall area predicted to be climatically suitable for its presence and the level of range filling varied across regions. A weak negative relationship among range filling and human impact was found. Overall climatic suitability was the strongest predictor of population performance. However, it showed high variability across regions: the effect was positive in Iberia whereas negative but not significant in Macaronesia and Morocco. Human impact showed a significant negative effect and finally topographic factors such as altitude had a minor negative effect. Our results highlight that both climate and human impact play a major role in the current limited range filling and performance of the species. Management plans to minimize anthropogenic disturbances together with reforestation measures are urgently needed in order to conserve this unique species.

Pregnant women often suffer from gastroesophageal reflux disease (GERD). GERD symptoms are known to influence the quality of life; however, there is a lack of data in pregnant women. The aim of this study was to establish the impact of GERD symptoms on health-related quality of life (HRQOL) during pregnancy. A prospective longitudinal cohort study to investigate the impact of GERD symptoms on the HRQOL was carried out in 510 pregnant women and 330 nonpregnant women as controls. Two validated questionnaires, the Reflux Disease Questionnaire and the Quality of Life in Reflux and Dyspepsia Questionnaire, were used. The study showed a significant negative impact on HRQOL in pregnant women with GERD symptoms. All five areas, emotional distress, sleep disturbance, vitality, food/drink problems, and physical/social functioning, were significantly reduced, but the most significant impact was on sleep (Quality of Life in Reflux and Dyspepsia Questionnaire score -35%). Overall, quality of life in women with GERD worsened throughout pregnancy. GERD is frequently seen in pregnant women and has a negative impact on HRQOL, especially in late pregnancy. Therefore, there is a need for adequate therapy of GERD in pregnant women and HRQOL could be an adequate monitoring tool in this population.

Gerontological educators are increasingly interested in reducing college students' negative, and promoting their positive, attitudes toward older adults. Over the course of a semester, students from six 4-year institutions viewed three life story videos (documentaries) of older adults and completed pre- and posttest surveys that assessed their positive (Allophilia Scale) and negative (Fraboni Scale of Ageism) attitudes. The authors assessed changes in attitudinal scales between treatment (with videos, n = 80) and control (no video, n = 40) groups. Change score analysis with 95% bias-corrected bootstrap confidence intervals estimated the effects of the documentaries on students' attitudes. The treatment group showed significant increases in kinship, engagement, and enthusiasm, and decreases in antilocution and avoidance (all ps <.05). There was no significant change in affect, comfort, or discrimination. This study demonstrated how video stories impact students' attitudes about older adults.

Background Personality disordered offenders (PDOs) are generally considered difficult to manage and to have a negative impact on staff working with them. Aims This study aimed to provide an overview of studies examining the impact on staff of working with PDOs, identify impact areas associated with working with PDOs, identify gaps in existing research,and direct future research efforts. Methods The authors conducted a systematic review of the English-language literature from 1964–2014 across 20 databases in the medical and social sciences. Results 27 papers were included in the review. Studies identified negative impacts upon staff including: negative attitudes, burnout, stress, negative counter-transferential experiences; two studies found positive impacts of job excitement and satisfaction, and the evidence related to perceived risk of violence from PDOs was equivocal. Studies demonstrated considerable heterogeneity and meta-analysis was not possible. The overall level of identified evidence was low: 23 studies (85%) were descriptive only, and only one adequately powered cohort study was found. Conclusions The review identified a significant amount of descriptive literature, but only one cohort study and no trials or previous systematic reviews of literatures. Clinicians and managers working with PDOs should be aware of the potential impacts identified, but there is an urgent need for further research focusing on the robust evaluation of interventions to minimise harm to staff working with offenders who suffer from personality disorder.

Evidence-based assessments are increasingly recognized as the best-practice approach to determine appropriate conservation interventions, but such assessments of the impact of human disturbance on wildlife are rare. Human disturbance comprises anthropogenic activities that are typically non-lethal, but may cause short- and/or longer-term stress and fitness responses in wildlife. Expanding human activity in the Antarctic region is of particular concern because it increases the scope and potential for increased human disturbance to wildlife in a region that is often thought of as relatively untouched by anthropogenic influences. Here, we use a meta-analytical approach to synthesise research on human disturbance to wildlife over the last three decades in the Antarctic and sub-Antarctic region. We combine data from 62 studies across 21 species on the behavioural, physiological and population responses of wildlife to pedestrian, vehicle and research disturbances. The overall effect size indicated a small, albeit statistically significant negative effect of disturbance (-0.39; 95% CI: -0.60 to -0.18). Negative effects were found for both physiological and population responses, but no evidence was found for a significant impact on wildlife behavioural responses. Negative effects were found across pedestrian, vehicle and research disturbances. Significant and high among-study heterogeneity was found in both disturbance and response sub-groups. Among species, it remains unclear to what extent different forms of disturbance translate into negative population responses. Most current guidelines to limit wildlife disturbance impacts in Antarctica recommend that approaches be tailored to animal behavioural cues, but our work demonstrates that behavioural changes do not necessarily reflect more cryptic, and more deleterious impacts, such as changes in physiology. In consequence, we recommend that pedestrian approach guidelines in the Antarctic region be revisited. Due to the high heterogeneity in effects, management guidelines for different sites and species will need to be developed on a case-by-case basis, ideally in conjunction with carefully designed experiments. Guidelines to reduce the impact of research activities per se require development to reduce the potential impacts of conducting research. We identify research questions that, if answered, will further improve the evidence base for guidelines to manage human disturbance in Antarctica. © 2015 Cambridge Philosophical Society.

Turnover among registered nurses (RNs) produces a negative impact on the health outcomes of any health care organization. It is also recognized universally as a problem in the nursing profession. Little is known about the turnover intentions and career orientations of RNs working in Calgary, Alberta, Canada. The aim of this study is to contribute to the knowledge of and to advance the discussion on the turnover of nursing professionals. The study population consisted of RNs employed in the five major hospitals in Calgary. There were 193 surveys returned, representing a response rate of 77.2%. The results show that age and education have a negative effect on turnover intention. Education was found to have a significant negative effect on career satisfaction but not on job satisfaction and organizational commitment. Length of service has a significant negative effect on turnover intention. Role ambiguity has significant highly negative effect on career satisfaction. Growth opportunity and supervisor support have a very significant positive effect on job satisfaction, career satisfaction, and organizational commitment. External career opportunities and organizational commitment do not seem to have a significant effect on turnover intention. Career satisfaction, on the other hand, had negative significant effects on turnover intention.

This study examined the impact of parental modeled behavior and permissibility of alcohol use in late high school on the alcohol use and experienced negative drinking consequences of college students. Two-hundred ninety college freshmen at a large university were assessed for perceptions of their parents’ permissibility of alcohol use, parents’ alcohol-related behavior, and own experienced negative consequences associated with alcohol use. Results indicate that parental permissibility of alcohol use is a consistent predictor of teen drinking behaviors, which was strongly associated with experienced negative consequences. Parental modeled use of alcohol was also found to be a risk factor, with significant differences being seen across the gender of the parents and teens. Discussion focuses on risk factors and avenues for prevention research. PMID:19398278

2016-12-01

In order to evaluate the impact of semi-intensive shrimp farming, comparisons between Control and Impact areas were made based on multiple lines of evidence using an asymmetrical design. Water and sediment samples were collected in four shrimp farms located in Todos os Santos Bay, Bahia, Brazil. Nutrients, trace elements and macrobenthic assemblages were evaluated using uni- and multivariate analyzes. Significant differences were observed between Impact and Control areas for the water column dataset (i.e., ancillary variables, SPM, dissolved nutrients and major and trace elements in SPM), whereas no significant differences were observed for the chemistry of sediments. Macrobenthic assemblages were negatively affected by shrimp farm activities. Impacted sites presented the lowest abundance, richness and different structure of macrofaunal benthic assemblages. Farms clearly produced negative impacts in the Todos os Santos Bay. This conclusion was only possible to be reached through the use of multiple lines of evidence. Chemistry and benthic assemblages data combined produced a better description of the quality and impacts of the evaluated environments. Different conclusions would have been reached if chemistry and ecology results were studied separately vs. together. Copyright © 2016 Elsevier Ltd. All rights reserved.

Publication bias may affect the validity of evidence based medical decisions. The aim of this study is to assess whether research outcomes affect the dissemination of clinical trial findings, in terms of rate, time to publication, and impact factor of journal publications. All drug-evaluating clinical trials submitted to and approved by a general hospital ethics committee between 1997 and 2004 were prospectively followed to analyze their fate and publication. Published articles were identified by searching Pubmed and other electronic databases. Clinical study final reports submitted to the ethics committee, final reports synopses available online and meeting abstracts were also considered as sources of study results. Study outcomes were classified as positive (when statistical significance favoring experimental drug was achieved), negative (when no statistical significance was achieved or it favored control drug) and descriptive (for non-controlled studies). Time to publication was defined as time from study closure to publication. A survival analysis was performed using a Cox regression model to analyze time to publication. Journal impact factors of identified publications were recorded. Publication rate was 48·4% (380/785). Study results were identified for 68·9% of all completed clinical trials (541/785). Publication rate was 84·9% (180/212) for studies with results classified as positive and 68·9% (128/186) for studies with results classified as negative (p<0·001). Median time to publication was 2·09 years (IC95 1·61-2·56) for studies with results classified as positive and 3·21 years (IC95 2·69-3·70) for studies with results classified as negative (hazard ratio 1·99 (IC95 1·55-2·55). No differences were found in publication impact factor between positive (median 6·308, interquartile range: 3·141-28·409) and negative result studies (median 8·266, interquartile range: 4·135-17·157). Clinical trials with positive outcomes have significantly higher rates and shorter times to publication than those with negative results. However, no differences have been found in terms of impact factor.

In 2006, El Paso County, a predominantly Hispanic urban area, was affected by a flood disaster; 1,500 homes were damaged. We assessed the health impacts of the disaster upon 475 individuals whose homes were flood-damaged using mail survey data and logistic regression. Substantial proportions of individuals had one or more physical (43 %) or mental (18 %) health problem in the four months following the floods; 28 % had one or more injury or acute effect related to post-flood cleanup. Adverse event experiences, older age, and lower socioeconomic status were significantly associated with negative post-flood health outcomes in all three logistic regression models. A lack of access to healthcare, non-US citizenship, and English proficiency were significant predictors of negative outcomes in both the physical and mental health models, while Hispanic ethnicity (physical), native-birth (mental), and more serious home damage (cleanup) were significant predictors in one model each. The disaster had disproportionate negative health impacts on those who were more exposed, poorer, older, and with constrained resource-access. While a lack of US citizenship and Hispanic ethnicity were associated with higher risks, being less acculturated (i.e., English-deficient, foreign-born) may have protected against health impacts.

Outsourcing labor is linked to negative impacts on occupational health and safety (OHS). In British Columbia, Canada, provincial health care service providers outsource support services such as cleaners and food service workers (CFSWs) to external contractors. This study investigates the impact of outsourcing on the occupational health safety of hospital CFSWs through a mixed methods approach. Worker's compensation data for hospital CFSWs were analyzed by negative binomial and multiple linear regressions supplemented by iterative thematic analysis of telephone interviews of the same job groups. Non-significant decreases in injury rates and days lost per injury were observed in outsourced CFSWs post outsourcing. Significant decreases (P < 0.05) were observed in average costs per injury for cleaners post outsourcing. Outsourced workers interviewed implied instances of underreporting workplace injuries. This mixed methods study describes the impact of outsourcing on OHS of healthcare workers in British Columbia. Results will be helpful for policy-makers and workplace regulators to assess program effectiveness for outsourced workers.

Climate change is expected to have major impacts on high alpine and arctic ecosystems in the future, but empirical data on the impact of long-term warming on lichen diversity and richness are sparse. This study report the effects of 18 years of ambient and experimental warming on lichens and vascular plant cover in two alpine plant communities, a dry heath with sparse canopy cover (54 %) and a mesic meadow with a more developed (67 %) canopy cover, in sub-arctic Sweden. The effects of long-term passive experimental warming using open top chambers (OTCs) on lichens and total vascular plant cover, and the impact of plant cover on lichen community parameters, were analysed. Between 1993 and 2013, mean annual temperature increased about 2 °C. Both site and experimental warming had a significant effect on cover, species richness, effective number of species evenness of lichens, and total plant canopy cover. Lichen cover increased in the heath under ambient conditions, and remained more stable under experimental warming. The negative effect on species richness and effective number of species was driven by a decrease in lichens under experimental warming in the meadow. Lichen cover, species richness, effective number of species evenness were negatively correlated with plant canopy cover. There was a significant negative impact on one species and a non-significant tendency of lower abundance of the most common species in response to experimental warming. The results from the long-term warming study imply that arctic and high alpine lichen communities are likely to be negatively affected by climate change and an increase in plant canopy cover. Both biotic and abiotic factors are thus important for future impacts of climate change on lichens. © The Author 2017. Published by Oxford University Press on behalf of the Annals of Botany Company.

Bricker-Katz, Geraldine; Lincoln, Michelle; McCabe, Patricia

2009-01-01

The International Classification of Functioning, Disability and Health (ICF) framework has a pragmatic focus on how impairment impacts the individual's activities and participation. Stuttering is known to impact communication in younger adults but this has not been established in older people who stutter. In this study, emotional reactions to stuttering were investigated in a group 55 years and older who self-reported stuttering since childhood. This was a cross-sectional descriptive design. Twelve participants who self-reported that they still stuttered and in whom stuttering was confirmed, and 14 controls completed the Fear of Negative Evaluation Scale (FNES), The Endler Multi-dimensional Anxiety Scales-Trait (EMAS-T) and The Australian Personal Wellbeing Index (PWA-I). Participants whose stuttering persisted also completed the Overall Assessment of Speakers Experience of Stuttering (OASES). The group who stuttered scored significantly higher on the FNES, with scores in the social phobia range. Responses on the OASES showed that stuttering continues to be a negative experience for this older group. Results for the EMAS-T and PWA-I were within the average range across both participant groups however significant differences existed between the groups in the social evaluative and physical danger domains of the EMAS-T, and the satisfaction with health domain of the PWA-I. Significant fear of negative evaluation, which is the key feature for social anxiety, was found in the group of older people who stuttered with a higher level of trait anxiety in social evaluative domains. The OASES showed that they also reacted to stuttering and communication in daily situations with moderate to severe impact scores which showed that stuttering impacted on speaking activities and by those negative experiences limited communication. Limited communication and restricted participation in the lives of older people have implications for healthy productive ageing and this is discussed.

The false-negative rate of sentinel node biopsy in patients with breast cancer: a meta-analysis

Background/Purpose In sentinel node surgery for breast cancer, procedural accuracy is assessed by calculating the false-negative rate. It is important to measure this since there are potential adverse outcomes from missing node metastases. We performed a meta-analysis of published data to assess which method has achieved the lowest false-negative rate. Methods We found 3588 articles concerning sentinel nodes and breast cancer published from 1993 through mid-2011; 183 articles met our inclusion criteria. The studies described in these 183 articles included a total of 9306 patients. We grouped the studies by injection material and injection location. The false-negative rates were analyzed according to these groupings and also by the year in which the articles were published. Results There was significant variation in the false-negative rate over time with a trend to higher rates over time. There was significant variation related to injection material. The use of blue dye alone was associated with the highest false-negative rate. Inclusion of a radioactive tracer along with blue dye resulted in a significantly lower false-negative rate. Although there were variations in the false-negative rate according to injection location, none were significant. This meta-analysis also indicates a significant change over time in the false-negative rate. Discussion/Conclusions The use of blue dye should be accompanied by a radioactive tracer to achieve a significantly lower false-negative rate. Location of injection did not have a significant impact on the false-negative rate. Given the limitations of acquiring appropriate data, the false-negative rate should not be used as a metric for training or quality control. PMID:22569745

Spiritual Well-being May Reduce the Negative Impacts of Cancer Symptoms on the Quality of Life and the Desire for Hastened Death in Terminally Ill Cancer Patients.

Spirituality is a central component of the well-being of terminally ill cancer patients. The aim of this study was to examine the mediating or moderating role of spiritual well-being in reducing the impact of cancer-related symptoms on quality of life and the desire for hastened death in terminally ill cancer patients. Eighty-five terminally ill cancer patients were assessed using the Taiwanese version of the M. D. Anderson Symptom Inventory, the Functional Assessment of Cancer Therapy-General, the Functional Assessment of Chronic Illness Therapy-Spiritual Well-being, the Beck Hopelessness Scale, and the Schedule of Attitudes Toward Hastened Death. Spiritual well-being was significantly negatively correlated with symptom severity (r = -0.46, P < .01). Symptom severity negatively correlated with quality of life (r = -0.54) and positively correlated with hopelessness (r = 0.51, P < .01) and the desire for hastened death (r = 0.61, P < .01). Spiritual well-being was a partial mediator and moderator between symptom severity and quality of life. Spiritual well-being was a partial mediator between symptom severity and the desire for hastened death. The meaning subscale of spiritual well-being was a more significant predictor of the desire for hastened death and quality of life than the faith subscale was. Spiritual well-being may reduce the negative impacts of cancer on quality of life and the desire for hastened death. Appropriate spiritual care may reduce the negative impact of severe cancer symptoms on quality of life and the desire for hastened death in terminally ill cancer patients.

This cohort study examined the impact of cancer on sexual function and intimate relationships in adolescents and young adults (AYAs). We also explored factors predicting an increased likelihood that cancer had negatively affected these outcomes. Participants (n = 465, ages 15-39) in the Adolescent and Young Adult Health Outcomes and Patient Experience (AYA HOPE) study completed two surveys approximately 1 and 2 years post-cancer diagnosis. We used multivariable logistic regression to determine factors negatively affected by perceptions of sexual function at 2 years post-diagnosis. Forty-nine percent of AYAs reported negative effects on sexual function at 1 year post-cancer diagnosis and 70% of those persisted in their negative perceptions 2 years after diagnosis. Those reporting a negative impact at 2 years were more likely to be 25 years or older (OR, 2.53; 95% CI, 1.44-4.42), currently not raising children (OR, 1.81; 95% CI, 1.06-3.08), experiencing fatigue (OR, 0.99; 95% CI, 0.975-0.998) and more likely to report that their diagnosis has had a negative effect on physical appearance (OR, 3.08; 95% CI, 1.97-4.81). Clinical factors and mental health were not significant predictors of negative effects on sexual function. Many AYAs diagnosed with cancer experience a persistent negative impact on sexual life up to 2 years following diagnosis. The findings underscore the need to develop routine protocols to assess sexual function in AYAs with cancer and to provide comprehensive management in the clinical setting.

Negative life events have impact on mental health and skin diseases among adults. Itch is a common, disabling skin symptom. The aim was to describe negative life events associated with current itch and to analyze the impact of number of negative life events on symptoms of itch, controlling for possible confounders. This school-based longitudinal survey was conducted among 15 and 18 years old high-school students in Oslo, Norway. From a baseline cohort of 3811 students, 2489 (65%) participants were followed-up after three years later. They completed questionnaires at baseline and follow-up. Current itch was measured with a validated instrument asking for symptoms on a four point Likert scale at follow-up. More girls than boys reported itch. There were no gender differences in number of negative life events. Death among close relative/friend was the most common negative life event among boys and girls. All negative life experiences before 15 years of age were statistically significantly associated with itch, but after 15 years only half of the negative life events were associated with itch. The bivariate association between number of negative life events and itch was statistically significant, and only when adjusting for mental distress at baseline there was a considerable drop in the Odds Ratio. There is a clear association between number of negative life events at baseline and itch at follow-up three years later among adolescents. It is therefore important to discuss possible adverse experiences with adolescents presenting with severe symptoms of itch. Copyright © 2011 Elsevier Inc. All rights reserved.

Patients' Perspectives of Oral Healthcare Providers' Communication: Considering the Impact of Message Source and Content.

PubMed

Fico, Ashley E; Lagoe, Carolyn

2018-08-01

This study explores patients' perceptions of positive and negative communication experiences with dentists and dental hygienists using a sample of 267 individuals who reported having a general dental provider. Patients' oral health literacy, dental mistrust, use of dental health services, anxiety, and provider satisfaction are examined on the basis of reported communication experiences in the dental context. When comparing participants who had or had not experienced positive communication with a dentist, individuals with positive experiences demonstrated significantly higher levels of oral health literacy and provider satisfaction, as well as lower levels of dental mistrust. Participants who had experienced negative communication with a dentist reported significantly higher levels of anxiety and dental mistrust, as well as greater likelihood of ever leaving a dental practice, as compared to those without negative communication experiences. By contrast, positive and negative communication experiences with hygienists had limited impact on patient outcomes. Information derived from this investigation can be used by dental providers to guide communicative actions with patients, as well as by scholars to enhance existing theoretical explanations of the function of communication in dentistry.

The study quantifies the impact of terrorism and political instability on firm equity premium in Pakistan using panel data for 306 non-financial firms for the period 2001 to 2014. Other variables included are law & order, government regime change and financial crisis of 2007/08. The estimated results reveal that terrorism has statistically significant negative impact on firm equity premium in Pakistan. This result is robust with alternative equation specifications. The result also remains same when terrorism variable is replaced with external and internal conflict variables. Law & order variable has significant positive effect on firm equity premium, which implies that equity premium increases with the improvement in law & order situation in the country. Equity premium also increases with government stability and when there is democratic system in the country. The result also reveals that global financial crisis of 2007/08 negatively influenced the firm equity premium. The study suggests some policy implications.

To examine the effects of electronic health information technology (HIT) on nursing home residents. The study evaluated the impact of implementing a comprehensive HIT system on resident clinical, functional, and quality of care outcome indicators as well as measures of resident awareness of and satisfaction with the technology. The study used a prospective, quasi-experimental design, directly assessing 761 nursing home residents in 10 urban and suburban nursing homes in the greater New York City area. No statistically significant impact of the introduction of HIT on residents was found on any outcomes, with the exception of a significant negative effect on behavioral symptoms. Residents' subjective assessment of the HIT intervention were generally positive. The absence of effects on most indicators is encouraging for the future development of HIT in nursing homes. The single negative finding suggests that further investigation is needed on possible impact on resident behavior. © The Author(s) 2012

Background. After 2 decades of focused efforts to eradicate polio, the impact of eradication activities on health systems continues to be controversial. This study evaluated the impact of polio eradication activities on routine immunization (RI) and primary healthcare (PHC). Methods. Quantitative analysis assessed the effects of polio eradication campaigns on RI and maternal healthcare coverage. A systematic qualitative analysis in 7 countries in South Asia and sub-Saharan Africa assessed impacts of polio eradication activities on key health system functions, using data from interviews, participant observation, and document review. Results. Our quantitative analysis did not find compelling evidence of widespread and significant effects of polio eradication campaigns, either positive or negative, on measures of RI and maternal healthcare. Our qualitative analysis revealed context-specific positive impacts of polio eradication activities in many of our case studies, particularly disease surveillance and cold chain strengthening. These impacts were dependent on the initiative of policy makers. Negative impacts, including service interruption and public dissatisfaction, were observed primarily in districts with many campaigns per year. Conclusions. Polio eradication activities can provide support for RI and PHC, but many opportunities to do so remain missed. Increased commitment to scaling up best practices could lead to significant positive impacts. PMID:24690667

Association Between Personality Traits and Oral Health-Related Quality of Life: A Cross-Sectional Study.

PubMed

Montero, Javier; Gómez-Polo, Cristina

The aim of this study was to investigate the oral health-related quality of life (OHRQoL) among subjects with typical, atypically positive, and atypically negative personality trait scores within the five basic dimensions of personality (neuroticism, extroversion, openness, agreeableness, and conscientiousness). A total of 235 subjects not seeking dental treatment were recruited from the families and acquaintances of dental students from the University of Salamanca. The 14-item Oral Health Impact Profile (OHIP-14) was used to capture the impact on their OHRQoL. The Neouroticism-Extroversion-Openness Personality Inventory Revised was applied to assess personality profiles. People were classified as having negatively atypical, typical, or positively atypical (PAP) personality, depending on whether the sum of the Z scores was < -1, between -1 and 1, or > 1, respectively. Pearson correlation, analysis of variance, and logistic regression test were used for the statistical analyses. The sample was comprised of highly educated adults (aged 18-80 years) with good oral health habits. PAP subjects suffered significantly more in the dimension of psychologic discomfort (0.6 ± 0.7) than did their counterparts (0.3 ± 0.6), but the global impact in OHRQoL was comparable. Personality was weakly correlated with OHIP-14. The perception of dental treatment needs was found to be the major predictor of the impact on OHRQoL, but the number of negatively atypical deviated personality traits and the agreeableness raw score also had an effect. The risk of perceiving an impact on OHRQoL is significantly higher in individuals perceiving treatment needs and increases proportionally to the number of negatively atypical personality traits.

Off-road vehicle use is arguably one of the most environmentally damaging human activities undertaken on sandy beaches worldwide. Existing studies focused on areas of high traffic volumes have demonstrated significantly lower abundance, diversity and species richness of fauna in zones where traffic is concentrated. The impact of lower traffic volumes is unknown. This study aimed to investigate the impacts of relatively low-level vehicle traffic on sandy beach fauna by sampling invertebrate communities at eight beaches located in south-western Australia. We found that even low-level vehicle traffic negatively impacts the physical beach environment, and consequently, the ability of many species to survive in this habitat in the face of this disturbance. Compaction, rutting and displacement of the sand matrix were observed over a large area, resulting in significant decreases in species diversity and density, and measurable shifts in community structure on beaches that experienced off-road vehicle traffic. Communities at impact sites did not display seasonal recovery as traffic was not significantly different between seasons. Given a choice between either reducing traffic volumes, or excluding ORV traffic from beaches, our results suggest that the latter would be more appropriate when the retention of ecological integrity is the objective.

Attention and material-specific memory in children with lateralized epilepsy.

PubMed

Engle, Jennifer A; Smith, Mary Lou

2010-01-01

Epilepsy is frequently associated with attention and memory problems. In adults, lateralization of seizure focus impacts the type of memory affected (left-sided lesions primarily impact verbal memory, while right-sided lesions primarily impact visual memory), but the relationship between seizure focus and the nature of the memory impairment is less clear in children. The current study examines the correlation between parent-reported attention problems and material-specific memory (verbal or visual-spatial) in 65 children (ages 6-16) with medically intractable lateralized epilepsy. There were no significant differences in attention and memory between those with left-lateralized epilepsy (n=25) and those with right-lateralized epilepsy (n=40). However, in the left-lateralized group attention problems were significantly negatively correlated only with delayed visual memory (r=-.450, p<.05), while the right-lateralized group demonstrated the opposite pattern (attention problems significantly negatively correlated with delayed verbal memory; r=-.331, p<.05). These findings suggest that lateralization of seizure focus may in fact impact children's memory in a material-specific manner, while problems with attention may impact memory more globally. Therefore, interventions designed to improve attention in children with epilepsy may have utility in improving certain aspects of memory, but further suggest that in children with lateralized epilepsy, material-specific memory deficits may not resolve with such interventions.

Objectives Published negative studies should have the same rigour of methodological quality as studies with positive findings. However, the methodological quality of negative versus positive studies is not known. The objective was to assess the reported methodological quality of positive versus negative studies published in Indian medical journals. Design A systematic review (SR) was performed of all comparative studies published in Indian medical journals with a clinical science focus and impact factor >1 between 2011 and 2013. The methodological quality of randomised controlled trials (RCTs) was assessed using the Cochrane risk of bias tool, and the Newcastle-Ottawa scale for observational studies. The results were considered positive if the primary outcome was statistically significant and negative otherwise. When the primary outcome was not specified, we used data on the first outcome reported in the history followed by the results section. Differences in various methodological quality domains between positive versus negative studies were assessed by Fisher's exact test. Results Seven journals with 259 comparative studies were included in this SR. 24% (63/259) were RCTs, 24% (63/259) cohort studies, and 49% (128/259) case–control studies. 53% (137/259) of studies explicitly reported the primary outcome. Five studies did not report sufficient data to enable us to determine if results were positive or negative. Statistical significance was determined by p value in 78.3% (199/254), CI in 2.8% (7/254), both p value and CI in 11.8% (30/254), and only descriptive in 6.3% (16/254) of studies. The overall methodological quality was poor and no statistically significant differences between reporting of methodological quality were detected between studies with positive versus negative findings. Conclusions There was no difference in the reported methodological quality of positive versus negative studies. However, the uneven reporting of positive versus negative studies (72% vs 28%) indicates a publication bias in Indian medical journals with an impact factor of >1. PMID:26109118

Perceived impact of cancer among adolescents and young adults: Relationship with health-related quality of life and distress.

Husson, O; Zebrack, B J

2017-09-01

To examine whether perceptions of the impact of cancer are related to health-related quality of life (HRQoL) and psychological distress among survivors of cancer in adolescence and young adulthood (AYA). One hundred seventy-three AYA cancer survivors (aged 18-35 and 15-29 years at time of diagnosis) completed a mailed survey assessing impact of cancer (IOC-AYA), HRQoL (SF-36), and distress (BSI-18). Hierarchical linear regression models analyzed the independent effects of perceived impacts of cancer on HRQoL and distress after controlling for clinical and sociodemographic characteristics. Multivariate analyses also examined the extent to which positive and negative perceptions attenuated the effects of control variables on HRQoL and distress. Being unemployed or not in school, and self-reported health problems were significantly associated with worse physical HRQoL. Mental HRQoL and psychological distress appeared as a function of reporting both positive and negative impacts of cancer; mental health outcomes were better in AYAs reporting more positive and less negative impact of cancer in their lives. Perceived impact of cancer, in both positive and negative ways, attenuated the effects of sociodemographic and clinical factors on mental HRQoL and psychological distress. Results suggest that mental HRQoL and psychological distress, but not physical HRQoL, are a function of survivors' perceptions of how cancer has affected them and continues to affect them in both positive and negative ways. Findings suggest that opportunities for AYA cancer survivors to reframe or better understand the context of cancer in their lives may result in improved mental health outcomes.

Sobral, Dilermando; Rosenbaum, Marcy; Figueiredo-Braga, Margarida

2015-07-08

This study evaluated how physicians and patients perceive the impact of computer use on clinical communication, and how a patient-centered orientation can influence this impact. The study followed a descriptive cross-sectional design and included 106 family physicians and 392 patients. An original questionnaire assessed computer use, participants' perspective of its impact, and patient centered strategies. Physicians reported spending 42% of consultation time in contact with the computer. A negative impact of computer in patient-physician communication regarding the consultation length, confidentiality, maintaining eye contact, active listening to the patient, and ability to understand the patient was reported by physicians, while patients reported a positive effect for all the items. Physicians considered that the usual computer placement in their consultation room was significantly unfavorable to patient-physician communication. Physicians perceive the impact of computer use on patient-physician communication as negative, while patients have a positive perception of computer use on patient-physician communication. Consultation support can represent a challenge to physicians who recognize its negative impact in patient centered orientation. Medical education programs aiming to enhance specific communication skills and to better integrate computer use in primary care settings are needed. Copyright © 2015 Elsevier Ireland Ltd.

Although negative symptoms are a barrier to recovery from schizophrenia, little is understood about the psychological processes that reinforce and sustain them. To explore this issue, this study used structural equation modeling to test whether the impact of social withdrawal and emotion recognition deficits upon negative symptoms is mediated by the richness or poverty of personal narratives. The participants were 99 adults with schizophrenia spectrum disorders. Social cognition was assessed using the Bell-Lysaker Emotional Recognition Task; social withdrawal, using the Quality of Life Scale; narrative coherence, using the Scale To Assess Narrative Development; and negative symptoms, using the Positive and Negative Syndrome Scale. The findings reveal that although social cognition deficits and social withdrawal are significantly associated with negative symptom severity, these relationships become nonsignificant when personal narrative integrity is examined as a mediating factor. These results indicate that the development of personal narratives may be directly linked to the severity of negative symptoms; this construct may be a useful target for future interventions.

'Sorry, I meant the patient's left side': impact of distraction on left-right discrimination.

PubMed

McKinley, John; Dempster, Martin; Gormley, Gerard J

2015-04-01

Medical students can have difficulty in distinguishing left from right. Many infamous medical errors have occurred when a procedure has been performed on the wrong side, such as in the removal of the wrong kidney. Clinicians encounter many distractions during their work. There is limited information on how these affect performance. Using a neuropsychological paradigm, we aim to elucidate the impacts of different types of distraction on left-right (LR) discrimination ability. Medical students were recruited to a study with four arms: (i) control arm (no distraction); (ii) auditory distraction arm (continuous ambient ward noise); (iii) cognitive distraction arm (interruptions with clinical cognitive tasks), and (iv) auditory and cognitive distraction arm. Participants' LR discrimination ability was measured using the validated Bergen Left-Right Discrimination Test (BLRDT). Multivariate analysis of variance was used to analyse the impacts of the different forms of distraction on participants' performance on the BLRDT. Additional analyses looked at effects of demographics on performance and correlated participants' self-perceived LR discrimination ability and their actual performance. A total of 234 students were recruited. Cognitive distraction had a greater negative impact on BLRDT performance than auditory distraction. Combined auditory and cognitive distraction had a negative impact on performance, but only in the most difficult LR task was this negative impact found to be significantly greater than that of cognitive distraction alone. There was a significant medium-sized correlation between perceived LR discrimination ability and actual overall BLRDT performance. Distraction has a significant impact on performance and multifaceted approaches are required to reduce LR errors. Educationally, greater emphasis on the linking of theory and clinical application is required to support patient safety and human factor training in medical school curricula. Distraction has the potential to impair an individual's ability to make accurate LR decisions and students should be trained from undergraduate level to be mindful of this. © 2015 John Wiley & Sons Ltd.

Reimbursement decisions of the All Wales Medicines Strategy Group: influence of policy and clinical and economic factors.

Linley, Warren G; Hughes, Dyfrig A

2012-09-01

There have been several explorations of factors influencing the reimbursement decisions of the National Institute for Health and Clinical Excellence (NICE) but not of other UK-based health technology assessment (HTA) organizations. This study aimed to explore the factors influencing the recommendations of the All Wales Medicines Strategy Group (AWMSG) on the use of new medicines in Wales. Based on public data, logistic regression models were developed to evaluate the influence of cost effectiveness, the quality and quantity of clinical evidence, disease characteristics (including rarity), budget impact, and a range of other factors on the recommendations of AWMSG and its subcommittee, the New Medicines Group (NMG). Multivariate analyses of 47 AWMSG appraisals between 2007-9 correctly predicted 87% of decisions. The results are suggestive of a positive influence on recommendations of the presence of probabilistic sensitivity analyses (PSAs) but, counter-intuitively, a statistically significant negative influence of evidence from high-quality randomized controlled trials (RCTs) [odds ratio 0.059; 95% CI 0.005, 0.699]. This latter observation may be attributed to our strict definition of high quality, which excluded the use of surrogate endpoints. Putative explanatory variables, including cost effectiveness, budget impact, underlying disease characteristics and 'ultra'-orphan drug status were not statistically significant predictors of final AWMSG decisions based on our dataset. Univariate analyses indicate that medicines with negative recommendations had significantly higher incremental cost-effectiveness ratios than those with positive recommendations, consistent with the pursuit of economic efficiency. There is also evidence that AWMSG considers equity issues via an ultra-orphan drugs policy. Consideration of decision uncertainty via PSA appears to positively influence the reimbursement decisions of AWMSG. The significant negative impact of the presence of high-quality RCTs, and the lack of a significant positive impact of other expected factors, may reflect issues in the plausibility of supporting evidence for medicines that received negative recommendations. Furthermore, it serves to emphasize the difficulties in applying the usual hierarchies of evidence to the HTA process, and in particular to the appraisal of high-cost specialist medicines close to market launch.

It has been widely accepted that there is a close relationship between the land use type and water quality. There have been some researches on this relationship from the perspective of the spatial configuration of land use in recent years. This study aims to analyze the influence of various land use types on the water quality within the Chaohu Lake Basin based on the water quality monitoring data and RS data from 2000 to 2008, with the small watershed as the basic unit of analysis. The results indicated that there was significant negative correlation between forest land and grassland and the water pollution, and the built-up area had negative impacts on the water quality, while the influence of the cultivated land on the water quality was very complex. Besides, the impacts of the landscape diversity on the indicators of water quality within the watershed were also analyzed, the result of which indicated there was a significant negative relationship between them. The results can provide important scientific reference for the local land use optimization and water pollution control and guidance for the formulation of policies to coordinate the exploitation and protection of the water resource.

The National Institute for Health and Clinical Excellence (NICE) recommended the Oncotype DX ® Breast Recurrence Score ® (RS) assay as an option for informing adjuvant chemotherapy decisions in node-negative, oestrogen receptor (ER)+, human epidermal growth factor receptor 2 (HER2)-negative early breast cancer assessed to be at intermediate risk of recurrence based on clinicopathological factors. We evaluated the impact of RS testing on adjuvant chemotherapy decision-making in routine clinical practice in a UK Cancer Network. RS testing was performed in 201 females with newly diagnosed, ER+, HER2-negative, invasive breast cancer who underwent breast surgery with curative intent, were calculated to have a >3% overall survival benefit at 10 years from adjuvant chemotherapy based on PREDICT, and were considered for adjuvant chemotherapy. The impact of RS testing on adjuvant treatment decisions/associated cost was assessed. In all patients, the multi-disciplinary team recommended chemotherapy but the RS result allowed 127/201 patients (63.2%) to avoid unnecessary adjuvant chemotherapy. Amongst ER+, HER2-negative, node-negative patients (eligible for Oncotype DX testing in UK guidelines), 60.3% were spared chemotherapy. In node-positive patients, the assay reduced the use of chemotherapy by 69.2%. The use of RS testing to guide treatment in these 201 patients was associated with significant cost saving (when considering the cost of RS testing for all patients plus chemotherapy and its associated cost for 74 patients). Incorporating RS testing into routine clinical practice for selected node-negative and node-positive breast cancer patients significantly reduces the use of chemotherapy (p < 0.001) with its associated morbidity and costs.

Koïvogui, Akoï; Carbunar, Aurel; Imounga, Laure-Manuella; Laruade, Christelle; Laube, Sylvaine

Analyze the impact of educational level, negative beliefs and negative attitudes on the yellow fever vaccination coverage (YFVC). This analytical study involved a sample of 2763 people from 866 households. Educational status was described in six levels: No level (Respondent had never attended school), level-1 (respondent left before intermediate school), level-2 (Respondent attended intermediate school), level-3 (respondent attended high school), level-4 (Respondent attended university), Other level (When the level could not be determined). The Attitude towards vaccination was described in terms of person's availability to recommend vaccination to third. The relationships were analyzed by multivariate mixed logistic regression. Among the 2763 peoples, 2039 (73.8%) were vaccinated against yellow fever. People who left high school with or without the French baccalaureate were more likely to be vaccinated against YF than people without any diploma (OR = 1.4; p < 0.05). The probability of being vaccinated among people with negative attitudes was reduced by 40% (OR = 0.6; p < 0.05). Low level of education, negative beliefs and negative attitudes have significant impacts on YFVC. Negatives beliefs and attitudes result often from a major lack of information about the benefits of vaccination. This deficit is exacerbated in persons with low educational level.

In recent years, there have been many reports about a possible association between Stressful Life Events (SLE) and the onset of Graves' Disease (GD). Nevertheless, most papers have been criticised and no such association has yet been proven. To assess the possible associations between SLE and the onset of GD. Retrospective study of 62 subjects, divided into 2 groups of 31 each, GD (Gp1) and controls (Gp2). The patients in Gp1 had thyroid disease diagnosed within the last 12 months, with clinical and biochemical confirmation. In Gp2, psychopathological and endocrine disturbances had been ruled out. Each 2 group consisted of 9 males (29%) and 22 females (71%). The mean age was 38.48 + 10.9 in Gp1 and 41.1 + 11.8 in Gp2. SLE evaluation (number and impact) was reported for the 12 months preceding the onset of symptoms of thyroid disease. To assess SLE, we used the Life Experiences Survey-LES from Saranson, Johnson and Siegel (1978; 1985). Statistical analysis was done using Mann-Whitney and Kruskal-Wallis tests. Patients with GD had a significantly greater number of SLEs compared to Controls (p < .001). The number and impact of negative SLEs was significantly higher in Gp1 compared to Gp2 (p < .001). There were no significant differences between the groups in terms of the number and impact of both positive and neutral SLEs. The findings of this study support that SLEs may contribute to the precipitation of GD. We observed that patients with GD had significantly more negative events and experienced a greater negative impact from them prior to the onset of GD. The association of SLEs with GD is probably related to the association of stress with changes in the immune system, which can play an important role in the aetiology of thyrotoxicosis.

Impact of disaster-related mortality on gross domestic product in the WHO African Region

Background Disaster-related mortality is a growing public health concern in the African Region. These deaths are hypothesized to have a significantly negative effect on per capita gross domestic product (GDP). The objective of this study was to estimate the loss in GDP attributable to natural and technological disaster-related mortality in the WHO African Region. Methods The impact of disaster-related mortality on GDP was estimated using double-log econometric model and cross-sectional data on various Member States in the WHO African Region. The analysis was based on 45 of the 46 countries in the Region. The data was obtained from various UNDP and World Bank publications. Results The coefficients for capital (K), educational enrolment (EN), life expectancy (LE) and exports (X) had a positive sign; while imports (M) and disaster mortality (DS) were found to impact negatively on GDP. The above-mentioned explanatory variables were found to have a statistically significant effect on GDP at 5% level in a t-distribution test. Disaster mortality of a single person was found to reduce GDP by US$0.01828. Conclusions We have demonstrated that disaster-related mortality has a significant negative effect on GDP. Thus, as policy-makers strive to increase GDP through capital investment, export promotion and increased educational enrolment, they should always keep in mind that investments made in the strengthening of national capacity to mitigate the effects of national disasters expeditiously and effectively will yield significant economic returns.

This study investigated the relationships between tics, obsessive-compulsive symptoms (OCS), and impulsivity, and their effects on global functioning in Japanese patients with Tourette syndrome (TS), using the dimensional approach for OCS. Fifty-three TS patients were assessed using the Yale Global Tic Severity Scale, the Dimensional Yale-Brown Obsessive-Compulsive Scale, the Impulsivity Rating Scale, and the Global Assessment of Functioning Scale. Although tic severity scores were significantly and positively correlated with OCS severity scores, impulsivity severity scores were not significantly correlated with either. The global functioning score was significantly and negatively correlated with tic and OCS severity scores. Of the 6 dimensional OCS scores, only aggression scores had a significant negative correlation with global functioning scores. A stepwise multiple regression analysis showed that only OCS severity scores were significantly associated with global functioning scores. Despite a moderate correlation between tic severity and OCS severity, the impact of OCS on global functioning was greater than that of tics. Of the OCS dimensions, only aggression had a significant impact on global functioning. Our findings suggest that it is important to examine OCS using a dimensional approach when analyzing global functioning in TS patients. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

To evaluate current knowledge of the impact of non-medical switching on clinical and economic outcomes, resource utilization and medication-taking behavior. The literature was searched (Medline and Web of Science, January 2000-November 2015) to identify United States' studies evaluating ≥25 patients and measuring the impact of non-medical switching of drugs (switching to a chemically distinct but similar medication for reasons other than lack of clinical efficacy/response, side effects or poor adherence) on ≥1 clinical, economic, resource utilization or medication-taking behavior outcome. The direction of association between non-medical switching and outcomes was classified as negative or positive if a statistically significant worsening or improvement was reported, or neutral if no significant difference was observed. Twenty-nine studies contributed 96 outcomes (60.4% clinical; 21.9% resource utilization; 13.5% economic; 4.2% medication-taking behavior) within six disease categories (cardio-metabolic, immune-mediated, acid suppression, psychiatric, hormone replacement therapy and pain). The direction of association was more frequently negative (33.3%) or neutral (55.2%) than it was positive (11.5%). Stratified by outcome type, non-medical switching was negatively associated with clinical, economic, healthcare utilization and medication-taking behavior outcomes in 20.7%, 69.2%, 38.1% and 75.0% of cases, respectively; and positively in only 4.8%-17.2% of outcomes subgroups. Of 32 outcomes in patients demonstrating stable/well controlled disease, 68.8% and 31.3% had a negative and neutral direction of association. In patients without demonstrated disease stability, outcomes were negatively, neutrally and positively impacted by non-medical switching in 15.6%, 67.2% and 17.2% of 64 outcomes. Our inability to evaluate specific disease state categories and studies/outcomes received equal weight regardless of sample size or magnitude of effect. Non-medical switching was more often associated with negative or neutral effects than positive effects on an array of important outcomes. Among patients with stable/well controlled disease, non-medical switching was associated with mostly negative effects.

Impact of malocclusion on oral health related quality of life in young people

2013-01-01

Background The objectives for this study were to assess Oral Health Related Quality of Life (OHRQoL) in young people aged 15–25 who sought orthodontic treatment, and to measure the association between orthodontic treatment need (using the IOTN), sex, age and education level, and oral health related quality of life (OHRQoL). Methods Survey of a consecutive series of 323 young adults aged 15 to 25 years, attending orthodontic clinics at the Faculty of Dentistry, Universiti Teknologi MARA. Participants completed the Oral Health Impact Profile-14 (OHIP-14) and had a clinical examination including the Index of Orthodontic Treatment Need- Dental Health Component (IOTN-DHC). Data analyses included descriptive statistics, One-way ANOVA and bivariate and multivariate regression models. Results The mean overall score (± SD) for OHIP-14 in young people aged 15–25 was 22.6 ± 12.5. The psychological discomfort domain was the domain where highest impact was recorded with a mean (± SD) of 4.0 ± 1.9. The regression analyses showed a significant association of IOTN-DHC with overall OHIP-14 score (p < 0.05). Although females reported a slightly higher impact than males, this was not significant in both bivariate and multivariate analyses. Age group had a significant negative association with overall OHIP-14 score (p < 0.05). The 15–18 year old group showed the highest impact on their quality of life due to malocclusion. Participants with a university education report a significantly higher impact on OHRQoL as compared to participants with only secondary education. Conclusion Malocclusion has a significant negative impact on OHRQoL and its domains. This is greatest for the psychological discomfort domain. Younger people and those with a university education report higher levels of impact. There was no reported difference in impact between male and females. PMID:23443041

Negative life events of anxiety disordered children: bad fortune, vulnerability, or reporter bias?

2002-01-01

This article seeks to examine the nature of negative life events of anxiety-disordered children: to what extent are they unique, to what extent are they shared with siblings, and when they are shared, is the impact similar or different? Twenty-five anxiety-disordered children aged 8 to 13 years, referred to a child psychiatric clinic, were compared with matched non-clinical controls, and with their nearest in age nonreferred sibling aged 6 to 13 years on the number of parent-reported stressful life events. Anxiety-disordered children differ significantly from well controls in the number of negative life events reported by their parents over their lifetime, and the year preceding referral. Anxiety disordered children also differ significantly from their non-referred nearest in age sibling in the number of negative life events, both non-shared and shared. The difference in shared events is due to differences in appraisal by the parents of the impact of a shared event on the respective children. The often reported finding that children with anxiety disorders have experienced more negative life events than their healthy peers is partially due to objective differences in the occurrence of these events, but may also reflect heightened vulnerability or reporter bias.

Data on the impact of abnormal cervical smear results on health-related quality of life (HrQoL) are scarce. We aimed to (i) prospectively assess the HrQoL of women who were informed of an abnormal smear result; (ii) identify predictors of greater negative psychosocial impact of an abnormal result; and (iii) prospectively estimate the quality-adjusted life-years (QALYs) lost following an abnormal result. Between 08/2006 and 08/2008, 492 women with an abnormal result and 460 women with a normal result, frequency matched for age and clinic, were recruited across Canada. HrQoL was measured at recruitment and 4 and 12 weeks later with the EuroQol, Short Form-12, short Spielberg State-Trait Anxiety Inventory (STAI) and HPV Impact Profile. Three blocks of potential predictors of higher psychosocial impact were tested by hierarchical modeling: (i) socio-demographics; (ii) sexual activity; and (iii) smear result severity, communication, and understanding. Receiving an abnormal result significantly increased anxiety (STAI mean difference between both groups = 8.3). Initial anxiety decreased over time for the majority of women. However, 35% of women had clinically meaningful anxiety at 12 weeks (i.e. STAI scores ≥0.5 standard deviation of the controls). These women reported a lower socio-economic level, did not completely understand the information about their result and perceived themselves at higher risk of cancer. QALY lost following an abnormal result were between 0.007 and 0.009. Receiving an abnormal smear has a statistically significant and clinically meaningful negative impact on mental health. However, this negative impact subsides after 12 weeks for the majority of women. Copyright © 2011 John Wiley & Sons, Ltd.

Fibromyalgia is a chronic condition of unknown aetiology, characterised by widespread pain, sleep disturbances, and fatigue. In this paper we examined the relationship metacognitions and the impact of Fibromyalgia in a German sample, detailing the translation and validation of a self-report metacognitive instrument. The Metacognitions about Symptoms Control Scale (MaSCS) was translated into German using the back-forward translation process. A total of 348 patients (316 female and 26 male) with Fibromyalgia contributed data to the study to test the structure and psychometric properties of the MaSCS. Confirmatory factor analyses, informed by modification indices, resulted in a 16-item scale consisting of two factors pertaining to positive and negative metacognitions about symptoms control. Further analyses revealed that both factors had good internal consistency. Correlation analyses established convergent validity, indicating that both factors were significantly associated with: (1) established positive and negative metacognitions scales; and (2) with symptoms severity in Fibromyalgia. Regression analyses revealed that positive metacognitions about symptoms control significantly predicted impairment in physical functioning while negative metacognitions about symptoms control significantly predicted the overall Fibromyalgia impact value, when controlling for stress, anxiety, and depression and a general metacognitions. The findings support the potential relevance of metacognitions, and utility of the German version of MaSCS, in examining the role of metacognitions in Fibromyalgia and other chronic health conditions.

How to mitigate impacts of wind farms on bats? A review of potential conservation measures in the European context

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

Peste, Filipa, E-mail: filipapeste@gmail.com; Department of Biology, University of Aveiro; Paula, Anabela

Wind energy is growing worldwide as a source of power generation. Bat assemblages may be negatively affected by wind farms due to the fatality of a significant number of individuals after colliding with the moving turbines or experiencing barotrauma. The implementation of wind farms should follow standard procedures to prevent such negative impacts: avoid, reduce and offset, in what is known as the mitigation hierarchy. According to this approach avoiding impacts is the priority, followed by the minimisation of the identified impacts, and finally, when residual negative impacts still remain, those must be offset or at least compensated. This papermore » presents a review on conservation measures for bats and presents some guidelines within the compensation scenario, focusing on negative impacts that remain after avoidance and minimisation measures. The conservation strategies presented aim at the improvement of the ecological conditions for the bat assemblage as a whole. While developed under the European context, the proposed measures are potentially applicable elsewhere, taking into consideration the specificity of each region in terms of bat assemblages present, landscape features and policy context regarding nature and biodiversity conservation and management. An analysis of potential opportunities and constraints arising from the implementation of offset/compensation programmes and gaps in the current knowledge is also considered. - Highlights: • Wind energy impacts bat populations in ways not yet fully understood. • As the use of windfarms is growing worldwide greater impacts on bat populations are also expected. • Mitigation hierarchy provides a way to reduce impacts from new wind farm facilities. • Compensation measures may be used to reduce the residual effects on bat populations. • Identify bats ecological needs and compensate according to the existing surroundings.« less

The main purpose of this work is to analyze the impact of environmental degradation proxied by CO2 emissions per capita along with some other explanatory variables namely energy use, trade, and human capital on economic growth in selected higher CO2 emissions economies namely China, the USA, India, and Japan. For empirical analysis, annual data over the period spanning between 1971 and 2013 are used. After using relevant and suitable tests for checking data properties, the panel fully modified ordinary least squares (FMOLS) method is employed as an analytical technique for parameter estimation. The panel group FMOLS results reveal that almost all variables are statistically significant, whereby test rejects the null hypotheses of non cointegration, demonstrating that all variables play an important role in affecting the economic growth role across countries. Where two regressors namely CO2 emissions and energy use show significantly negative impacts on economic growth, for trade and human capital, they tend to show the significantly positive impact on economic growth. However, for the individual analysis across countries, the panel estimate suggests that CO2 emissions have a significant positive relationship with economic growth for China, Japan, and the USA, while it is found significantly negative in case of India. The empirical findings of the study suggest that appropriate and prudent policies are required in order to control pollution emerging from areas other than liquefied fuel consumption. The ultimate impact of shrinking pollution will help in supporting sustainable economic growth and maturation as well as largely improve society welfare.

Red imported fire ant impacts on upland arthropods in Southern Mississippi

Epperson, D.M.; Allen, Craig R.

2010-01-01

Red imported fire ants (Solenopsis invicta) have negative impacts on a broad array of invertebrate species. We investigated the impacts of fire ants on the upland arthropod community on 20???40 ha study sites in southern Mississippi. Study sites were sampled from 19972000 before, during, and after fire ant bait treatments to reduce fire ant populations. Fire ant abundance was assessed with bait transects on all sites, and fire ant population indices were estimated on a subset of study sites. Species richness and diversity of other ant species was also assessed from bait transects. Insect biomass and diversity was determined from light trap samples. Following treatments, fire ant abundance and population indices were significantly reduced, and ant species diversity and richness were greater on treated sites. Arthropod biomass, species diversity and species richness estimated from light trap samples were negatively correlated with fire ant abundance, but there were no observable treatment effects. Solenopsis invicta has the potential to negatively impact native arthropod communities resulting in a potential loss of both species and function.

Impact of targeting insulin-like growth factor signaling in head and neck cancers.

Limesand, Kirsten H; Chibly, Alejandro Martinez; Fribley, Andrew

2013-10-01

The IGF system has been shown to have either negative or negligible impact on clinical outcomes of tumor development depending on specific tumor sites or stages. This review focuses on the clinical impact of IGF signaling in head and neck cancer, the effects of IGF targeted therapies, and the multi-dimensional role of IRS 1/2 signaling as a potential mechanism in resistance to targeted therapies. Similar to other tumor sites, both negative and positive correlations between levels of IGF-1/IGF-1-R and clinical outcomes in head and neck cancer have been reported. In addition, utilization of IGF targeted therapies has not demonstrated significant clinical benefit; therefore the prognostic impact of the IGF system on head and neck cancer remains uncertain.

Williams, Allison M; Wang, Li; Kitchen, Peter

2014-01-01

Using data from Statistic Canada's General Social Survey Cycle 21 (GSS 2007), this study explores whether differences exist in the impacts of care-giving among three groups of caregivers providing informal care either in the caregiver's or recipient's home, or in other locations within the community: (i) those providing end-of-life (EOL) care (n = 471); (ii) those providing long-term care (more than 2 years) for someone with a chronic condition or long-term illness (n = 2722); and (iii) those providing short-term care (less than 2 years) for someone with a chronic condition or long-term illness (n = 2381). This study lays out the variation in sociodemographic characteristics across the three caregiver groups while also building on our understanding of the differential impacts of care-giving through an analysis of determinants. All three groups of caregivers shared a number of sociodemographic characteristics, including being female, married, employed and living in a Census Metropolitan Area (CMA). With respect to health, EOL caregivers were found to have significantly higher levels of ‘fair or poor’ self-assessed health than the other two groups. Overall, the findings suggest that EOL caregivers are negatively impacted by the often additional role of care-giving, more so than both short-term and long-term caregivers. EOL caregivers experienced a higher proportion of negative impacts on their social and activity patterns. Furthermore, EOL caregivers incurred greater financial costs than the other two types of informal caregivers. The impacts of EOL care-giving also negatively influence employment for caregivers when compared with the other caregiver groups. Consequently, EOL caregivers, overall, experienced greater negative impacts, including negative health outcomes, than did long-term or short-term caregivers. This provides the evidence for the assertion that EOL care-giving is the most intense type of care-giving, potentially causing the greatest caregiver burden; this is shown through the greater negative impacts experienced by the EOL caregivers when compared with the short-term and long-term caregivers.

Environmental assessment is the process that decision-makers rely on to predict, evaluate, and prevent biophysical, social, and economic impacts of potential project developments. The determination of significance in environmental assessment is central to environmental management in many nations. We reviewed ten recent environmental impact assessments from British Columbia, Canada and systematically reviewed and scored significance determination and the approaches used by assessors, the use of thresholds in significance determination, threshold exceedances, and the outcomes. Findings of significant impacts were exceedingly rare and practitioners used a combination of significance determination approaches, most commonly relying upon reasoned argumentation. Quantitative thresholds were rarely employed, with less than 10% of the valued components evaluated using thresholds. Even where quantitative thresholds for significance were exceeded, in every case practitioners used a variety of rationales to demote negative impacts to non-significance. These reasons include combinations of scale (temporal and spatial) of impacts, an already exceeded baseline, model uncertainty and/or substituting less stringent thresholds. Governments and agencies can better protect resources by requiring clear and defensible significance determinations, by making government-defined thresholds legally enforceable and accountable, and by requiring or encouraging significance determination through inclusive and collaborative approaches.

Thompson, Sam

2013-01-01

Objective. To explore the influences of discrete positive and negative emotions on cooperation in the context of a social dilemma game. Design. Two controlled studies were undertaken. In Study 1, 69 participants were randomly assigned to an essay emotion manipulation task designed to induce either guilt, joy or no strong emotion. In Study 2, 95 participants were randomly assigned to one of the same three tasks, and the impact of emotional condition on cooperation was explored using a repeated Prisoner’s Dilemma Game. Results. Study 1 established that the manipulation task was successful in inducing the specified emotions. The analysis from Study 2 revealed no significant main effects for emotions, in contrast to previous research. However, there was a significant effect for participants’ pre-existing tendency to cooperate (social value orientation; SVO). Conclusion. Methodological explanations for the result are explored, including the possible impact of trial-and-error strategies, different cooperation games and endogenous vs exogenous emotions. PMID:24432196

2016-01-01

Background and Objectives Illicit drug use, particularly of cannabis, is common among opiate-dependent individuals, and has the potential to impact treatment in a negative manner. Methods To examine this, patterns of cannabis use prior to and during methadone maintenance treatment (MMT) were examined to assess possible cannabis-related effects on MMT, particularly during methadone stabilization. Retrospective chart analysis was used to examine outpatient records of patients undergoing MMT (n=91), focusing specifically on past and present cannabis use and its association with opiate abstinence, methadone dose stabilization, and treatment compliance. Results Objective rates of cannabis use were high during methadone induction, dropping significantly following dose stabilization. History of cannabis use correlated with cannabis use during MMT, but did not negatively impact the methadone induction process. Pilot data also suggested that objective ratings of opiate withdrawal decrease in MMT patients using cannabis during stabilization. Conclusions and Scientific Significance The present findings may point to novel interventions to be employed during treatment for opiate dependence that specifically target cannabinoid-opioid system interactions.

2017-11-01

To examine the impact of a hybrid-flipped model utilising active learning techniques, the researchers inverted one section of an undergraduate fluid mechanics course, reduced seat time, and engaged in active learning sessions in the classroom. We compared this model to the traditional section on four performance measures. We employed a propensity score method entailing a two-stage regression analysis that considered eight covariates to address the potential bias of treatment selection. First, we estimated the probability score based on the eight covariates, and second, we used the inverse of the probability score as a regression weight on the performance of learners who did not select into the hybrid course. Results suggest that enrolment in the hybrid-flipped section had a marginally significant negative impact on the total course score and a significant negative impact on homework performance, possibly because of poor video usage by the hybrid-flipped learners. Suggested considerations are also discussed.

Background: Arts in medicine programs have significant impacts on patients and staff in long-term care environments, but the literature lacks evidence of effectiveness on hospital units with shorter average lengths of stay. Methods: The qualitative study used individual structured interviews to assess the impacts of arts programming on job satisfaction, stress, unit culture, support, quality of care, and patient outcomes on a short-term medical-surgical unit, and used a qualitative cross comparison grounded theory methodology to analyze data. Results: The study confirmed that arts programming can positively affect unit culture, nursing practice, and quality of care on short-stay medical-surgical units. Significant insights related to nursing practice and the art program were found, including that music can cause negative distraction for staff. Conclusions: While positive impacts of arts programming on the medical-surgical environment are clear, potential negative effects also need to be considered in the development of practice protocols for artists.

This study examines maternal perceptions of paediatric atopic dermatitis (AD) on family and determines risk factors including severity of AD, maternal physical and mental health (MH), quality of life of patients and sociodemographics which predict a negative family impact. A cross-sectional assessment using the Dermatitis Family Impact Questionnaire Scale to assess the impact of AD on family, Infant's Dermatitis Quality of Life Index (<5-yrs old) or Children's Dermatitis Life Quality Index (5-17 yrs old) was used to measure health-related quality of life (HRQOL) of paediatric patients with AD. A 12-item Short-Form Health Survey (SF-12) was used to assess physical and MH of their mothers. Risk factors of adverse family impact were assessed using multiple regression analysis. One hundred and four patients with AD and their mothers were studied. Their mean ages (+/-s.d.) were respectively 6.4 +/- 4.3 and 37.2 +/- 6.6 yrs. In multiple regression analysis, Severity Scoring of Atopic Dermatitis (SCORAD) appeared to be associated with negative family impact and the association remained significant after adjustment for bio-psycho-social factors and HRQOL of patients. The association remained insignificant after adjustment for physical and MH of the mothers. Our results show that the severity of paediatric AD leads to negative family impact through reduction of physical and MH of the mothers, and is independent of patients' HRQOL and sociodemographics. The current approach for managing paediatric AD in Asian society could include early multidisciplinary intervention, aiming at enhancing physical and MH of mothers while minimizing negative impact on family and social isolation. Further research will be welcomed as the results of this study mainly applied to Asian society which could be different to populations from other geographic areas.

Examined the impact of domestic violence, child abuse, and attachment style on adolescent mental health and relationship functioning. Data were collected on 111 adolescents, ages 14 to 16, and their mothers. Results indicate that both attachment and family violence experiences negatively impact mental health. In addition, family violence significantly predicted attachment style. Significant protective and vulnerability factors included maternal psychological functioning, maternal positive parenting, and perceived social support from friends. However, findings provided only limited support for the model of attachment as a mediator of the impact of family violence on adolescent relationships.

(1) determine which antipsychotic side effects (SE) schizophrenic patients consider the most distressing during treatment with typical antipsychotics, (2) measure the impact of actual and past SE on patients' attitude toward antipsychotics and (3) assess the influence of both on adherence. The 213 schizophrenics, treated with conventional antipsychotics, were recruited in two psychiatric hospitals in Hamburg. Subjects were assessed about type and severity of present and past side effects and their attitude and adherence to antipsychotic treatment. The 82 (39%) patients presented present SE while 131 (61%) did not. Sexual dysfunctions (P < 0.001), extrapyramidal (P < 0.05) and psychic side effects (P < 0.05) were rated as significantly subjectively more distressing than sedation or vegetative side effects. Patients presenting with present SE compared with patients without present SE had a significantly more negative general attitude toward antipsychotics (P < 0.05), were more doubtful about their efficacy (P < 0.01) and were less likely to encourage a relative to take such a medication in case of need (P < 0.001). A regression analysis indicated that nonadherence was mainly influenced by negative general and efficacy attitudes toward antipsychotics and the experience of past or present antipsychotic side effects. All antipsychotic side effects, present or past, can have a durable negative impact on patient's attitude toward antipsychotic treatment and adherence. Non-adherence is mainly determined, among other factors, by these negative attitudes, which are partly influenced by the experience of past or present antipsychotic-induced side effects.

Arm morbidity (AM) arising from breast cancer (BC) treatment can detrimentally impact quality of life; often limiting a survivor's ability to participate in valued activities. The present study explored (a) the developmental time course of AM [restricted range of motion (ROM), pain, and arm volume changes], negative affect, and perceived disability in the immediate years post-surgery, and (b) the mediating role of perceived disability on the relationship between AM and negative affect over time. In this 5-year longitudinal study, BC survivors from four Canadian oncology clinics (n = 431) completed five annual clinical assessments, where differences in ROM (shoulder abduction, external rotation) and arm volume between the affected and non-affected arm were measured. The profile of mood states (POMS), disability of arm, shoulder, hand, and McGill Pain Questionnaire-Short form were completed. Results from general linear modeling showed that AM, negative affect, and perceived disability were greatest 1-year post-surgery, declined, and with the exception of arm volume changes, were significantly lower 5 years later. Negative affect was significantly associated with restrictions in shoulder abduction and external rotation (average r = -0.15; p < 0.05) and present arm pain (average r = 0.28, p < 0.01) at most assessments. The mediating role of perceived disability on the relationship between AM and negative affect was statistically significant in a majority of assessments. Perceived disability is the underlying factor driving the relationship between AM and mood disturbance over time. Rehabilitative therapy to improve survivors' functional well-being might mitigate the negative impacts of AM on emotional health.

Informal Caregivers Assisting People with Multiple Sclerosis

Huang, Chunfeng

2011-01-01

The objective of this study was to identify characteristics of informal caregivers, caregiving, and people with multiple sclerosis (MS) receiving this assistance that are associated with the strength of the care-giver/care recipient relationship. Data were collected in a national survey of informal caregivers and analyzed using an ordered logistic regression model to identify factors associated with caregiver perceptions of the strength of the relationship with the person with MS. The overall health of the person with MS was significantly associated with caregiver perceptions that providing assistance strengthened the caregiver/care recipient relationship, with poor health having a negative impact on the relationship. A spousal relationship between the caregiver and the person with MS was associated with significantly lower perceptions of a strengthened relationship. Conversely, caregiver perceptions that MS symptoms interfered with the independence of the person with MS in daily life were associated with caregiver perceptions of a strengthened relationship. Longer duration of caregiving and more hours per week spent providing assistance also were associated with a stronger relationship. In contrast, we found a significant negative association between caregiver perceptions that assisting the person with MS was burdensome and the strength of the relationship. Similarly, higher levels of education among caregivers tended to have a significantly negative impact on the caregiver/care recipient relationship. Our findings highlight the importance of addressing the needs and concerns of spousal caregivers. Health professionals who treat informal caregivers, as well as those treating people with MS, should be sensitive to the impact caregiving has on caregivers, especially spouses providing assistance.

Evaluate the prognostic and predictive impact of HPV-associated p16-expression and assess the combined prognostic impact of p16 and smoking on altered fractionated radiotherapy (AFRT) for oropharyngeal cancer (OPC) within the frames of the update of the Meta-Analysis of Radiotherapy in Carcinomas of Head and neck (MARCH). Patients with OPC, known tumor p16-status and smoking history were identified from the MARCH update, resulting in a dataset of 815 patients from four randomized trials (RTOG9003, DAHANCA6&7, RTOG0129, ARTSCAN). Analysis was performed using a Cox model stratified by trial and adjusted on gender, age, T-stage, N-stage, type of radiotherapy fractionation, p16, smoking. Primary endpoint was progression-free survival (PFS). In total, 465 patients (57%) had p16-positive tumors and 350 (43%) p16-negative. Compared to p16-negative, p16-positive patients had significantly better PFS (HR = 0.42 [95% CI: 0.34-0.51], 28.9% absolute increase at 10 years) and OS (HR = 0.40 [0.32-0.49], 32.1% absolute increase at 10 years). No interaction between p16-status and fractionation schedule was detected. Smoking negatively impacted outcome; in the p16-positive subgroup, never smokers had significantly better PFS than former/current smokers (HR = 0.49 [0.33-0.75], 24.2% survival benefit at 10 years). No predictive impact of p16-status on response to AFRT could be detected but the strong prognostic impact of p16-status was confirmed and especially p16-positive never smoking patients have superior outcome after RT.

Assessing Impacts on Unplanned Hospitalisations of Care Quality and Access Using a Structural Equation Method: With a Case Study of Diabetes

PubMed Central

Congdon, Peter

2016-01-01

Background: Enhanced quality of care and improved access are central to effective primary care management of long term conditions. However, research evidence is inconclusive in establishing a link between quality of primary care, or access, and adverse outcomes, such as unplanned hospitalisation. Methods: This paper proposes a structural equation model for quality and access as latent variables affecting adverse outcomes, such as unplanned hospitalisations. In a case study application, quality of care (QOC) is defined in relation to diabetes, and the aim is to assess impacts of care quality and access on unplanned hospital admissions for diabetes, while allowing also for socio-economic deprivation, diabetes morbidity, and supply effects. The study involves 90 general practitioner (GP) practices in two London Clinical Commissioning Groups, using clinical quality of care indicators, and patient survey data on perceived access. Results: As a single predictor, quality of care has a significant negative impact on emergency admissions, and this significant effect remains when socio-economic deprivation and morbidity are allowed. In a full structural equation model including access, the probability that QOC negatively impacts on unplanned admissions exceeds 0.9. Furthermore, poor access is linked to deprivation, diminished QOC, and larger list sizes. Conclusions: Using a Bayesian inference methodology, the evidence from the analysis is weighted towards negative impacts of higher primary care quality and improved access on unplanned admissions. The methodology of the paper is potentially applicable to other long term conditions, and relevant when care quality and access cannot be measured directly and are better regarded as latent variables.

This paper examines the impact of variability in impact of air pollution on life satisfaction (LS). Previous studies have shown robust negative impact of air pollution on subjective well-being (SWB). However, empirical studies that consider variability in air pollution effects through comparative city study are limited. This study provides comparative evaluation of two major Chinese cities: Beijing and Shanghai. We apply a geo-statistical spatial interpolation technique on pollution data from monitoring sites to estimate the Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2), coarse particles with a diameter between 2.5 and 10 μm (PM10) and fine particles with a diameter of 2.5 μm or less (PM2.5) pollution exposure of respondents of a survey conducted in 2016. The results show that all pollutants have robust negative impacts on LS for Beijing residents, whereas only SO2 and NO2 have significant negative impacts on LS for Shanghai residents; Per unit impact of SO2 is greater in Shanghai, and that of NO2 is greater in Beijing. Beijing and Shanghai residents have almost same monetary valuation for SO2 reduction but Beijing residents place approximately 1.5 times valuation on NO2 reduction compared to Shanghai residents. Moreover, the LS of Beijing residents is sensitive to temporal changes in the pollution level, whereas Shanghai residents are unaffected by such changes.

Research demonstrates a negative impact of sleep disturbance on mood and affect; however, the biological mechanisms mediating these links are poorly understood. Amygdala reactivity to negative stimuli has emerged as one potential pathway. Here, we investigate the influence of self-reported sleep quality on associations between threat-related amygdala reactivity and measures of negative affect and perceived stress. Analyses on data from 299 participants (125 men, 50.5% white, mean [standard deviation] age = 19.6 [1.3] years) who completed the Duke Neurogenetics Study were conducted. Participants completed several self-report measures of negative affect and perceived stress. Threat-related (i.e., angry and fearful facial expressions) amygdala reactivity was assayed using blood oxygen level-dependent functional magnetic resonance imaging. Global sleep quality was assessed using the Pittsburgh Sleep Quality Index. Amygdala reactivity to fearful facial expressions predicted greater depressive symptoms and higher perceived stress in poor (β values = 0.18-1.86, p values < .05) but not good sleepers (β values = -0.13 to -0.01, p values > .05). In sex-specific analyses, men reporting poorer global sleep quality showed a significant association between amygdala reactivity and levels of depression and perceived stress (β values = 0.29-0.44, p values < .05). In contrast, no significant associations were observed in men reporting good global sleep quality or in women, irrespective of sleep quality. This study provides novel evidence that self-reported sleep quality moderates the relationships between amygdala reactivity, negative affect, and perceived stress, particularly among men.

Published negative studies should have the same rigour of methodological quality as studies with positive findings. However, the methodological quality of negative versus positive studies is not known. The objective was to assess the reported methodological quality of positive versus negative studies published in Indian medical journals. A systematic review (SR) was performed of all comparative studies published in Indian medical journals with a clinical science focus and impact factor >1 between 2011 and 2013. The methodological quality of randomised controlled trials (RCTs) was assessed using the Cochrane risk of bias tool, and the Newcastle-Ottawa scale for observational studies. The results were considered positive if the primary outcome was statistically significant and negative otherwise. When the primary outcome was not specified, we used data on the first outcome reported in the history followed by the results section. Differences in various methodological quality domains between positive versus negative studies were assessed by Fisher's exact test. Seven journals with 259 comparative studies were included in this SR. 24% (63/259) were RCTs, 24% (63/259) cohort studies, and 49% (128/259) case-control studies. 53% (137/259) of studies explicitly reported the primary outcome. Five studies did not report sufficient data to enable us to determine if results were positive or negative. Statistical significance was determined by p value in 78.3% (199/254), CI in 2.8% (7/254), both p value and CI in 11.8% (30/254), and only descriptive in 6.3% (16/254) of studies. The overall methodological quality was poor and no statistically significant differences between reporting of methodological quality were detected between studies with positive versus negative findings. There was no difference in the reported methodological quality of positive versus negative studies. However, the uneven reporting of positive versus negative studies (72% vs 28%) indicates a publication bias in Indian medical journals with an impact factor of >1.

2015-04-01

To examine the effect of comprehensive psychological training on the mental health of recruits and to provide basis for promoting mental health among recruits in Xinjiang. From September to December, 2013, a convenience sampling was used to select 613 recruits from Xinjiang. These recruits were assigned to the training group (n=306) and the control group (n=307). The Simplified Coping Style Questionnaire,the Questionnaire of Armymen's Emotion Regulation Types and the Chinese Military Personnel Social Support Scale were used to evaluate the levels of mental health at the baseline and at the end of comprehensive psychological training. After comprehensive psychological training, the negative coping style score of the training group were significantly lower than the control group (P=0.000), and there were difference in cognitive focus (P=0.000) and behavior restrain (P=0.005); also, there was significant difference in social support scale (P<0.05). The coping style showed positive correlation with emotion regulation and all factors (P<0.05). Social support and all factors was positively correlated with positive coping style (P<0.05) and negatively correlated with negative coping style (P<0.05). Social support and all factors showed positive correlation with affective appeal and self comfort (P<0.05) and negative correlation with congnitive focus and behavior restrain (P<0.05). As shown by stepwise regression analysis,the positive and negative coping styles had statistically significant impacts on cognitive focus, affective appeal, behavior restrain, and self comfort (all P<0.05). Comprehensive psychological training is useful in improving the mental health of recruits.

Forgotten family members: the importance of siblings in early psychosis.

Bowman, Siann; Alvarez-Jimenez, Mario; Wade, Darryl; McGorry, Patrick; Howie, Linsey

2014-08-01

This paper reviews the evidence on the significance of sibling inclusion in family interventions and support during early psychosis. This narrative review presents the current research related to the importance of family work during early psychosis, the needs and developmental significance of siblings during adolescence and early adulthood, the protective effects of sibling relationships, and the characteristics of early psychosis relevant to the sibling experience. It will also review the evidence of the sibling experience in chronic physical illness and disability, as well as long-term psychotic illness. Despite the evidence that working with families is important during early psychosis, siblings have been largely ignored. Siblings are an important reciprocal relationship of long duration. They play an important role in development during adolescence and early adulthood. These relationships may be an underutilized protective factor due to their inherent benefits and social support. Developmental theories imply that early psychosis could negatively impact the sibling relationship and their quality of life, effecting personality development and health outcomes. The evidence shows that adolescent physical illness or disability has a significantly negative impact on the sibling's quality of life and increases the risk for the onset of mental health issues. Long-term psychotic illness also results in negative experiences for siblings. Current evidence shows that siblings in early psychosis experience psychological distress and changes in functional performance. Further research using standard measures is required to understand the impact early psychosis has on the sibling relationship and their quality of life. © 2013 Wiley Publishing Asia Pty Ltd.

The Impact of an Integrated Electronic Health Record Adoption on Nursing Care Quality.

PubMed

Walker-Czyz, AnneMarie

2016-01-01

The purpose of this study was to measure the impact of an integrated electronic health record (EHR) innovation adoption on the quality of nursing care delivered, including hospital-acquired falls, hospital-acquired pressure ulcers, ventilator-associated pneumonia (VAP), central line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), and costs measured in nursing hours. The impact on quality, cost, and nurse satisfaction measured in turnover rates before, during, and after implementation of EHR tools was also investigated. Little is known about the adoption patterns of computerized documentation by nursing and the effects on the practice environment. A quantitative, retrospective analysis using interrupted time series model of a large data set was conducted in a 431-bed urban hospital, with 10 medical surgical units and 2 critical care units. The research was constructed using the Diffusion of Innovations (DOI) theory. Incorporating electronic, evidenced-based practice (EBP) tools into bedside nurse's workflow promotes decision making at the point of care that may improve quality with no negative impact on direct cost. The data revealed that total falls, CAUTI, and CLABSI rates were positively impacted after the implementation of an integrated EHR. Hospital-acquired pressure ulcer and VAP rates were negatively impacted at the implementation period followed by a significant positive rate reduction that surpassed the preimplementation period. Cost indicators, measured in hours per patient day and overtime, were negatively impacted during the implementation period followed by a return to baseline. Nurse turnover had a significant increase from the preimplementation to postimplementation period and failed to return to baseline. This study confirms that nurses have the ability to positively impact the quality of patient care through successful innovation adoption related to the use of EBP computerized documentation tools at the bedside. This study further clarified the practice environment of nurses during DOI.

How does difficulty communicating affect the social relationships of older adults? An exploration using data from a national survey.

Palmer, Andrew D; Newsom, Jason T; Rook, Karen S

2016-01-01

Healthy social relationships are important for maintaining mental and physical health in later life. Less social support, smaller social networks, and more negative social interactions have been linked to depression, poorer immune functioning, lower self-rated health, increased incidence of disease, and higher mortality. Overwhelming evidence suggests that communication disorders adversely affect social relationships. Much less is known about whether some or all aspects of social relationships are negatively affected by a communication disorder. The relative impact of a communication disorder on social relationships, as compared to other kinds of disability, is also poorly understood. Data were analyzed from a representative national sample of community-dwelling adults aged 65 and older living in the continental United States (n=742). Results from multiple regressions indicated that difficulty communicating was significantly associated with several parameters of social relationships even after controlling for age, gender, partnership status, health, functional limitations, and visual impairment. Communication difficulty was a significant predictor of smaller social network size, fewer positive social exchanges, less frequent participation in social activities, and higher levels of loneliness, but was not a significant predictor of negative social exchanges. These findings suggest that communication disorders may place older adults at increased risk for mental and physical health problems because of social isolation, reduced social participation, and higher rates of loneliness. In addition, it appears that communication disorders may have a greater impact on positive, rather than negative, aspects of social relationships. As a result of this activity, the following learning outcomes will be realized: Readers will be able to (1) describe changes in the social relationships of older adults that occur as part of normal aging, (2) identify the aspects of social relationships that were significantly impacted by a communication difficulty, and (3) discuss possible reasons for these findings including potential clinical implications.

The clinical outcomes and cost implications of a diagnostic shift from an EIA- to PCR-based assay for Clostridium difficile infection (CDI) have not been completely described in the literature. The impact of the PCR-based assay on the incidence and duration of CDI therapy was compared to the EIA assay for patients with a negative CDI diagnostic result. Secondary clinical and economic outcomes were also evaluated. Independent predictors of receipt of antibiotic therapy were assessed via logistic regression. 141 EIA and 140 PCR patients were included. Significantly more patients were started or continued on anti-CDI antibiotic therapy after a known negative assay result in the EIA group (26 patients vs. 8 patients, P = 0.002). Duration of antibiotic therapy after a known negative result was significantly shorter in the PCR group (1 vs. 4 days, P = 0.029) and a 23% reduction in the number of tests obtained per patient was observed (1.41 ± 0.86 vs. 1.82 ± 1.35, P = 0.007). The over fourfold difference in per-test cost of the EIA assay ($8.33 vs. $42.86, P < 0.0001) was offset by the overall medication costs required for the increased treatment in the EIA group ($546.60 vs. $188.96, P = 0.191). Utilization of the EIA-based CDI assay was associated with increased odds of CDI treatment after a negative test (aOR 4.71, 95% CI 1.93-11.46, P = 0.001). The transition from an EIA to PCR-based assay for diagnosing CDI resulted in a significant decrease in the number of patients treated and the duration of treatment in response to a negative test result. This significant decrease in treatment resulted in decreased costs offsetting the utilization of a more expensive molecular test for patients with a negative CDI diagnostic result.

Psychosocial predictors of affect in adult patients undergoing orthodontic treatment.

Peñacoba, Cecilia; González, M José; Santos, Noelia; Romero, Martín

2014-02-01

In this paper we propose to study the role of psychosocial variables in affect in adult patients undergoing orthodontic treatment, considering that affect is a key variable in treatment adherence. Seventy-four patients (average age 33,24 ± 10,56) with metal multibracket-fixed orthodontic treatment were included. Patients were assessed twice. The first stage, at the beginning of treatment, included assessment of dental impact (Psychosocial Impact of Dental Aesthetics Questionnaire), trait anxiety (State-Trait Anxiety Inventory), self-esteem (Rosenberg's self-esteem scale), and self-efficacy (General Self-efficacy Scale). In the second stage, 6 months later, positive and negative affect towards treatment was assessed using the Positive and Negative Affect Scale. Dental social impact differentiates between patients with high and low negative affect, while self-efficacy differentiates between patients with high and low positive affect. Trait anxiety and self-esteem differentiate between both types of affect (positive and negative). Trait anxiety and self-esteem (when trait anxiety weight is controlled) are significant predictor variables of affective balance. These results have important practical implications, because it seems essential to adopt a bio-psychosocial model incorporating assessment methods focusing on day-to-day changes in mood and well-being.

Stomaching rejection: Self-compassion and self-esteem moderate the impact of daily social rejection on restrictive eating behaviours among college women.

Beekman, Janine B; Stock, Michelle L; Howe, George W

2017-11-01

The present study examined whether having high self-esteem or a self-compassionate perspective help mitigate the impact of daily social rejection on negative affect and restrictive eating behaviours. Following a baseline survey assessing self-esteem and self-compassion, 121 college women completed online daily diaries for one week. Negative affect and restrictive eating behaviours. On days when women reported more rejection, they also reported higher restrictive eating behaviours and greater negative affect. Effects were moderated by self-esteem and self-compassion, such that the lower participants were in self-esteem or self-compassion, the stronger the positive relation between rejection and negative affect and restrictive eating. However, only the common humanity/isolation dimension of self-compassion significantly moderated daily effects of rejection when controlling for self-esteem. Mediated moderation results reveal different mechanisms by which self-esteem and self-compassion buffer against rejections' effects on affect and restrictive eating. Self-compassion and self-esteem influence the complex impact that social rejection has on affect and restrictive eating. More than other dimensions of self-compassion or self-esteem, remembering one's common humanity can result in a healthier response to social rejection.

Urban renewal, gentrification and health equity: a realist perspective.

Up to now, research has focused on the effects of urban renewal programs and their impacts on health. While some of this research points to potential negative health effects due to gentrification, evidence that addresses the complexity associated with this relation is much needed. This paper seeks to better understand when, why and how health inequities arise from urban renewal interventions resulting in gentrification. A realist review, a qualitative systematic review method, aimed to better explain the relation between context, mechanism and outcomes, was used. A literature search was done to identify theoretical models of how urban renewal programs can result in gentrification, which in turn could have negative impacts on health. A systematic approach was then used to identify peer-reviewed studies that provided evidence to support or refute the initial assumptions. Urban renewal programs that resulted in gentrification tended to have negative health effects primarily in residents that were low-income. Urban renewal policies that were inclusive of populations that are vulnerable, from the beginning were less likely to result in gentrification and more likely to positively impact health through physical and social improvements. Research has shown urban renewal policies have significant impacts on populations that are vulnerable and those that result in gentrification can result in negative health consequences for this population. A better understanding of this is needed to impact future policies and advocate for a community-participatory model that includes such populations in the early planning stages.

6th Yahya Cohen Lecture: visual experience during cataract surgery.

Au Eong, K G

2002-09-01

The visual sensations many patients experience during cataract surgery under local anaesthesia have received little attention until recently. This paper reviews the recent studies on this phenomenon, discusses its clinical significance and suggests novel approaches to reduce its negative impact on the surgery. Literature review. Many patients who have cataract surgery under retrobulbar, peribulbar or topical anaesthesia experience a variety of visual sensations in their operated eye during surgery. These visual sensations include perception of light, movements, flashes, one or more colours, surgical instruments, the surgeon's hand/fingers, the surgeon and changes in light brightness. Some patients experience transient no light perception, even if the operation is performed under topical anaesthesia. The clinical significance of this phenomenon lies in the fact that approximately 7.1% to 15.4% of patients find their visual experience frightening. This fear and anxiety may cause some patients to become uncooperative during surgery and trigger a sympathetic surge, causing such undesirable effects as hypertension, tachycardia, ischaemic strain on the heart, hyperventilation and acute panic attack. Several approaches to reduce the negative impact of patients' visual experience are suggested, including appropriate preoperative counselling and reducing the ability of patients to see during surgery. The findings that some patients find their intraoperative visual experience distressing have a major impact on the way ophthalmologists manage their cataract patients. To reduce its negative impact, surgeons should consider incorporating appropriate preoperative counselling on potential intraoperative visual experience when obtaining informed consent for surgery.

Most strategies used to help improve the patient experience of care and ease emergency department (ED) crowding and diversion require additional space and personnel resources, major process improvement interventions, or a combination of both. To compare the impact of ED expansion vs. patient flow improvement and the establishment of a rapid assessment unit (RAU) on the patient experience of care in a medium-size safety net ED. This paper describes a study of a single ED wherein the department first undertook a physical expansion (2006 Q2 to 2007 Q2) followed by a reorganization of patient flow and establishment of an RAU (2009 Q2) by the use of an interrupted time series analysis. In the time period after ED expansion, significant negative trends were observed: decreasing Press Ganey percentiles (-4.1 percentile per quarter), increasing door-to-provider time (+4.9 minutes per quarter), increasing duration of stay (+13.2 minutes per quarter), and increasing percent of patients leaving without being seen (+0.11 per quarter). After the RAU was established, significant immediate impacts were observed for door-to-provider time (-25.8 minutes) and total duration of stay (-66.8 minutes). The trends for these indicators further suggested the improvements continued to be significant over time. Furthermore, the negative trends for the Press Ganey outcomes observed after ED expansion were significantly reversed and in the positive direction after the RAU. Our results demonstrate that the impact of process improvement and rapid assessment implementation is far greater than the impact of renovation and facility expansion. Copyright © 2016 Elsevier Inc.

A secondary data analysis of 25,560 minutes of structured clinical observations from a longitudinal study examined the impact of time-varying background factors, social environment, and psychotropic medication use on behavioral symptoms of nursing home residents with Alzheimer's disease (AD). Data were collected at baseline (N = 177), 12 months (N = 138), and 24 months (N = 111). Mixed-effects regression modeling showed that at 24 months: (a) higher cognitive and physical function and having a private bedroom/bathroom had the most positive influence on resident positive behaviors; (b) use of antipsychotic medications and solitary activities had the most negative influence on resident positive behaviors; (c) higher cognitive function significantly decreased negative behaviors; and (d) care-related activities and total number of psychotropic medications significantly increased negative behaviors. The current study describes risk factors for behavioral disturbances and the impact of activities, social environment, and psychotropic medications on behavioral outcomes in nursing home residents with AD.

This research is the first nationally representative study to examine the relationship between actual state-level tobacco control spending in each of the 5 CDC’s Best Practices for Comprehensive Tobacco Control Program categories and cigarette sales. We employed several alternative two-way fixed-effects regression techniques to estimate the determinants of cigarette sales in the United States for the years 2008–2012. State spending on tobacco control was found to have a negative and significant impact on cigarette sales in all models that were estimated. Spending in the areas of cessation interventions, health communication interventions, and state and community interventions were found to have a negative impact on cigarette sales in all models that were estimated, whereas spending in the areas of surveillance and evaluation, and administration and management were found to have negative effects on cigarette sales in only some models. Our models predict that states that spend up to seven times their current levels could still see significant reductions in cigarette sales. The findings from this research could help inform further investments in state tobacco control programs. PMID:29652890

It is still unclear whether insight has a direct association with social functioning in schizophrenia, independent of its association with symptoms. This study aimed to investigate the relationship of insight and its dimensions with social functioning in schizophrenia. A total of 170 outpatients with schizophrenia were included in this study. All patients were evaluated with the Scale to Assess Unawareness of Mental Disorder (SUMD), Positive and Negative Syndrome Scale (PANSS) and Personal and Social Performance Scale (PSP). Patients with impaired insight and patients with unimpaired insight were compared for PSP score through independent samples t test. Pearson's correlation analysis was used to determine the correlations between study variables. Multiple stepwise linear regression analysis was used in order to determine the variables that predict social performance. The PSP score of patients with impaired insight was significantly lower than that of patients with unimpaired insight. There were significant correlations between insight dimensions and PSP score. PANSS negative scale score, awareness of achieved effects of medication and awareness of anhedonia/asociality were significant predictors of social performance. Insight has a significant impact on social functioning in schizophrenia, and some, but not all, insight dimensions have direct impact on social performance, independent of their association with symptoms. © The Author(s) 2014.

The mediating role of depression and negative partner responses in chronic low back pain and relationship satisfaction.

PubMed

Waxman, Samantha E; Tripp, Dean A; Flamenbaum, Ricardo

2008-05-01

Chronic low back pain (CLBP) is a prevalent pain condition associated with increased disability, lower quality of life, and poor relationship satisfaction. However, little research has examined the impact of the psychosocial environment in predicting relationship satisfaction among persons with CLBP. This study examined empirically supported psychosocial variables as potential mediators in the association between pain and relationship satisfaction. Patients with CLBP completed depression, partner support, pain, relationship satisfaction, pain catastrophizing, and pain-related fear measures (N = 54). Negative responses by a partner and depression were found to mediate the association between pain and relationship satisfaction, with negative responses emerging as the most important mediator. The current findings are consistent with a biopsychosocial framework of chronic pain and suggest that negative interpersonal interactions in patients with CLBP may be of central importance when considering psychosocial intervention. Theoretical and practical implications for treatment are discussed. This study suggests that psychosocial variables, specifically depression and perceived negative partner responses, have a significant impact on relationship satisfaction among individuals with CLBP. These findings highlight issues integral to the social adjustment of patients with CLBP.

The Management of Myelomeningocele Study was a multicenter, randomized controlled trial that compared prenatal repair with standard postnatal repair for fetal myelomeningocele. We sought to describe the long-term impact on the families of the women who participated and to evaluate how the timing of repair influenced the impact on families and parental stress. Randomized women completed the 24-item Impact on Family Scale and the 36-item Parenting Stress Index Short Form at 12 and 30 months after delivery. A revised 15-item Impact on Family Scale describing overall impact was also computed. Higher scores reflected more negative impacts or greater stress. In addition, we examined Family Support Scale and Family Resource Scale scores along with various neonatal outcomes. Repeated measures analysis was conducted for each scale and subscale. Of 183 women randomized, 171 women completed the Impact on Family Scale and 172 completed the Parenting Stress Index at both 12 and 30 months. The prenatal surgery group had significantly lower revised 15-item Impact on Family Scale scores as well as familial-social impact subscale scores compared to the postnatal surgery group (P = .02 and .004, respectively). There was no difference in total parental stress between the 2 groups (P = .89) or in any of the Parenting Stress Index Short Form subscales. In addition, walking independently at 30 months and family resources at 12 months were associated with both family impact and parental stress. The overall negative family impact of caring for a child with spina bifida, up to 30 months of age, was significantly lower in the prenatal surgery group compared to the postnatal surgery group. Ambulation status and family resources were predictive of impact on family and parental stress. Copyright © 2016 Elsevier Inc. All rights reserved.

Improving the effectiveness of performance feedback by considering personality traits and task demands

Peterson, Jordan B.

2018-01-01

Although performance feedback is widely employed as a means to improve motivation, the efficacy and reliability of performance feedback is often obscured by individual differences and situational variables. The joint role of these moderating variables remains unknown. Accordingly, we investigate how the motivational impact of feedback is moderated by personality and task-difficulty. Utilizing three samples (total N = 916), we explore how Big Five personality traits moderate the motivational impact of false positive and negative feedback on playful, neutral, and frustrating puzzle tasks, respectively. Conscientious and Neurotic individuals together appear particularly sensitive to task difficulty, becoming significantly more motivated by negative feedback on playful tasks and demotivated by negative feedback on frustrating tasks. Results are discussed in terms of Goal-Setting and Self Determination Theory. Implications for industry and education are considered. PMID:29787593

High Job Demands, Still Engaged and Not Burned Out? The Role of Job Crafting.

PubMed

Hakanen, Jari J; Seppälä, Piia; Peeters, Maria C W

2017-08-01

Traditionally, employee well-being has been considered as resulting from decent working conditions arranged by the organization. Much less is known about whether employees themselves can make self-initiated changes to their work, i.e., craft their jobs, in order to stay well, even in highly demanding work situations. The aim of this study was to use the job demands-resources (JD-R model) to investigate whether job crafting buffers the negative impacts of four types of job demands (workload, emotional dissonance, work contents, and physical demands) on burnout and work engagement. A questionnaire study was designed to examine the buffering role of job crafting among 470 Finnish dentists. All in all, 11 out of 16 possible interaction effects of job demands and job crafting on employee well-being were significant. Job crafting particularly buffered the negative effects of job demands on burnout (7/8 significant interactions) and to a somewhat lesser extent also on work engagement (4/8 significant interactions). Applying job crafting techniques appeared to be particularly effective in mitigating the negative effects of quantitative workload (4/4 significant interactions). By demonstrating that job crafting can also buffer the negative impacts of high job demands on employee well-being, this study contributed to the JD-R model as it suggests that job crafting may even be possible under high work demands, and not only in resourceful jobs, as most previous studies have indicated. In addition to the top-down initiatives for improving employee well-being, bottom-up approaches such as job crafting may also be efficient in preventing burnout and enhancing work engagement.

The changing relationship between the December North Atlantic Oscillation and the following February East Asian trough before and after the late 1980s

This study investigates the changing relationship between the December North Atlantic Oscillation (NAO) and the following February East Asian trough (EAT) throughout the past 60 years. We found that the relationship between the December NAO and the following February EAT is significantly enhanced after the late 1980s compared with the period before the late 1980s. The changing relationship mainly results from the enhanced relationship between the December NAO and the following February North Atlantic mid-latitudes' sea surface temperature (SST) anomalies (NAMA) during the same period. During the period after the late 1980s, the persistent positive (negative) NAO pattern from December to the following January contributes to a positive (negative) NAMA, which reaches its maximum magnitude in the following February and excites an anomalous wave train along the North Atlantic and northern Eurasia, and significantly impacts the EAT. During the period before the late 1980s, the positive (negative) NAO pattern during December cannot persist into the following January, and the related positive (negative) NAMA is insignificant during the following February, causing the response of the simultaneous EAT to be insignificant as well. Moreover, there exists a significant impact of the December NAO on the December-January NAMA after the late 1980s, while the December-January NAMA is relatively less affected by the December NAO before the late 1980s. As a result, the simultaneous response of the atmospheric circulation anomalies to the December-January NAMA are evident before the late 1980s, and the positive (negative) NAMA can excite an anomalous wave train along the North Atlantic and northern Eurasia and significantly deepen (shallow) the downstream EAT. By contrast, after involving a feature of atmosphere forcing of SST, the simultaneous feedback of the December-January NAMA on EAT is significantly decreased after the 1980s.

Objective Although much attention has been given to the effects of adverse childhood experiences on the development of personality disorders (PDs), we know far less about how recent life events influence the ongoing course of functioning. We examined the extent to which PD subjects differ in rates of life events and the extent to which life events impact psychosocial functioning. Method A total of 633 subjects were drawn from the Collaborative Longitudinal Personality Disorders Study (CLPS), a multi-site study of four personality disorders – schizotypal (STPD), borderline (BPD), avoidant (AVPD), obsessive-compulsive (OCPD) – and a comparison group of major depressive disorders (MDD) without PD. Results Borderline personality disorder subjects reported significantly more total negative life events than other PDs or subjects with MDD. Negative events, especially interpersonal events, predicted decreased psychosocial functioning over time. Conclusion Our findings indicate higher rates of negative events in subjects with more severe PDs and suggest that negative life events adversely impact multiple areas of psychosocial functioning.

A cross-sectional study of 183 female Bathudis, a tribal population of the Keonjhar District, Orissa, India, was undertaken to investigate age variations in anthropometric and body composition characteristics and nutritional status. The subjects were categorized into three age groups: < or =30 years, 31-50 years, >50 years. Height, weight, circumferences and skinfolds data were collected. Body mass index (BMI) and several body composition variables and indices were derived using standard equations. The results revealed that there existed significant negative age variations for most of the anthropometric and body composition variables and indices. Correlation studies of age with these variables and indices revealed significant negative correlations. Linear regression analyses revealed that for all variables, age had a significant negative impact. Studies on the nutritional status of these women revealed that with increasing age, there was an increase in the frequency of undernutrition. In conclusion, this study demonstrated that among Bathudi women, age was significantly negatively related with anthropometric and body composition variables and indices. Moreover, with increasing age, the level of undernutrition increased.

Medical schools may select students for their attitudes towards rural medical practice, yet the rural-urban disparity in availability of medical practitioners and services has not diminished in recent times despite government initiatives and increasing numbers being trained for a career in medicine. One medical school, with a focus on rural and remote medicine, aims to select students with positive perceptions for rural medical practice. A research project collected data on the perceptions of these medical students in the first week of their medical studies. Students completed a low stakes essay on the life and work of a rural doctor. Initially, this formed part of a literacy assessment to determine any students requiring remediation. All students were asked if they would consent to their essay being reviewed for a research project. Data was obtained from those students who consented and handed their essays in for review. The 103 student essays underwent thematic analysis and sentences were coded into three main themes of rural lifestyle, doctor role and rural practice. Second level themes were further elicited and results were quantified according to whether they were positive or negative. Positive themes included rural lifestyle, doctor role, views of doctor, impact on community, broader work and skills knowledge, and better relationships with community and patients. Negative themes included doctor's health, pressure on doctor, family problems, greater workload, privacy and confidentiality issues, cultural issues, isolation, limited resources and financial impacts. Quantitisation of this data was used to transform essay sentences into a numerical form which allowed statistical analysis and comparison of perceptions using Z tests. No significant differences on the number of positive and negative responses for rural lifestyle and rural practice were found. The rural doctor role had a significantly more positive than negative views. Significant differences were found for positive views of the rural doctor role and negative views of rural practice. Participants from a capital city background reported a significantly higher percentage of responses related to negative views of rural practice than their regional and rural counterparts. Students from capital city areas had significantly more negative views about the rural doctor role, especially related to workload, limited resources and isolation than students from rural and regional areas. Students entering medical school already have both positive and negative views about the life and work of a rural doctor. Those students from capital city areas have significantly more negative views despite being selected to enter a medical course with a rural focus based on their expressed rural perceptions. Further work is required to refine selection criteria and the year level experiences and learning opportunities which may positively influence student perceptions about rural medical practice to overcome early negative perceptions at the beginning of medical school.

Does nitrogen affect the interaction between a native hemiparasite and its native or introduced leguminous hosts?

Cirocco, Robert M; Facelli, José M; Watling, Jennifer R

Associations between plants and nitrogen (N)-fixing rhizobia intensify with decreasing N supply and come at a carbon cost to the host. However, what additional impact parasitic plants have on their leguminous hosts' carbon budget in terms of effects on host physiology and growth is unknown. Under glasshouse conditions, Ulex europaeus and Acacia paradoxa either uninfected or infected with the hemiparasite Cassytha pubescens were supplied (high nitrogen (HN)) or not (low nitrogen (LN)) with extra N. The photosynthetic performance and growth of the association were measured. Cassytha pubescens significantly reduced the maximum electron transport rates and total biomass of U. europaeus but not those of A. paradoxa, regardless of N. Infection significantly decreased the root biomass of A. paradoxa only at LN, while the significant negative effect of infection on roots of U. europaeus was less severe at LN. Infection had a significant negative impact on host nodule biomass. Ulex europaeus supported significantly greater parasite biomass (also per unit host biomass) than A. paradoxa, regardless of N. We concluded that rhizobia do not influence the effect of a native parasite on overall growth of leguminous hosts. Our results suggest that C. pubescens will have a strong impact on U. europaeus but not A. paradoxa, regardless of N in the field. © 2016 The Authors. New Phytologist © 2016 New Phytologist Trust.

Effects of nonindigenous tadpoles on native tadpoles in Florida: Evidence of competition

Smith, Kimberly G.

2005-01-01

The impacts of nonindigenous species on native ecosystems can be severe, sometimes leading to the extinction of native taxa. Interspecific competition is a potential mechanism of negative impact of invasive species, but few studies have conclusively demonstrated competition between native and nonindigenous taxa. In this study I used experimental manipulations to examine the competitive effects of the larvae of two widely introduced anurans, the cane toad, Bufo marinus, and the Cuban treefrog, Osteopilus septentrionalis, on the growth and development of the larvae of two native anurans (the southern toad, Bufo terrestris, and the green treefrog, Hyla cinerea). The presence of O. septentrionalis larvae consistently impacted growth and development of native larvae, resulting in reduced growth rates and delayed metamorphosis of both native species and smaller mass at metamorphosis of B. terrestris. Hyla cinerea larvae transformed at greater body masses when reared with the rapidly transforming nonindigenous species as a result of competitive release. The negative effects of O. septentrionalis on native larvae were generally significant whether native tadpoles were exposed to O. septentrionalis alone or in combination with B. marinus. In contrast, B. marinus tadpoles did not significantly impact the growth or development of either native species. Neither nonindigenous species significantly decreased the survivorship of native larvae, although a trend toward decreased survivorship was evident for H. cinerea. These results suggest that nonindigenous larval anurans may adversely impact native tadpole communities as a result of interspecific competition.

'It's off to work we go!' Person-environment fit and turnover intentions in managerial and administrative mining personnel.

Person-environment fit asserts that incompatibility between an employee and aspects of their work environment is more likely to lead to occupational stress. The aim of this study was to investigate the impact that varying levels of person-environment fit had on key criterion outcomes including work engagement, work-related wellbeing and turnover intentions in a unique sample of managerial and administrative mining personnel. An online self-report survey was distributed to an Australian mining organization by the company's Chief Executive Officer. Anonymous survey links were sent to staff, of which 118 participants responded. The survey consisted of previously validated measures. Hierarchical multiple regression analyses revealed significant relationships between abilities-demand fit, needs-supply fit and work engagement. Additionally, work-related wellbeing was significantly associated with increased person-organization fit and needs-supply fit. However, only needs-supply fit had a significant negative relationship with turnover intentions. Needs-supply fit significantly predicted all criterion variables. This study found that personal need fulfilment through work-related activities had the most significant impact on work-related wellbeing and work engagement. Personal need fulfilment through work also produced the most significant negative relationship with turnover intentions.

ABSTRACT Objective: To evaluate the impact of dental trauma and impaired esthetics on the quality of life (QoL) of preschool children and their relatives. Methods: Study conducted with 192 children aged 2 to 5 years in 11 preschools in Florianópolis, Santa Catarina, South of Brazil. Parents/caregivers completed a questionnaire on quality of life (Brazilian version of the Early Childhood Oral Health Impact Scales - B-ECOHIS), a socioeconomic survey, and then answered specific questions related to dental trauma. The subjects were examined by three accordant examiners (Kappa>0.7). Dental trauma was evaluated on the basis of indexes adopted by the World Health Organization, and esthetic impairment was then classified. Data were descriptively analyzed and put to bivariate analysis by chi-square and Fisher tests, with significance level at 5%. Results: The prevalence of dental trauma was 62.5% with 15.6% of esthetic impairment. Almost 12% of parents reported impact on the quality of life of their children. Dental trauma was not significantly associated with gender, age or QoL. Crown color change by trauma was associated with esthetic impairment. Also esthetic impairment had a negative impact on QoL (p<0.05) and was associated with oral limitations (p<0.05). Conclusions: Esthetic impairment had a negative impact on children’s quality of life, while dental trauma was not associated to it. PMID:28977132

Optimism and positive and negative feelings in parents of young children with developmental delay.

Parents' positive and negative feelings about their young children influence both parenting behaviour and child problem behaviour. Research has not previously examined factors that contribute to positive and negative feelings in parents of young children with developmental delay (DD). The present study sought to examine whether optimism, a known protective factor for parents of children with DD, was predictive of positive and negative feelings for these parents. Data were collected from 119 parents of preschool-aged children with developmental delay. Two separate hierarchical linear regression analyses were conducted to determine if optimism significantly predicted positive feelings and negative feelings and whether optimism moderated relations between parenting stress and parent feelings. Increased optimism was found to predict increased positive feelings and decreased negative feelings after controlling for child problem behaviour and parenting stress. In addition, optimism was found to moderate the relation between parenting stress and positive feelings. Results suggest that optimism may impact how parents perceive their children with DD. Future research should examine how positive and negative feelings impact positive parenting behaviour and the trajectory of problem behaviour specifically for children with DD. © 2017 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Healthy social relationships are important for maintaining mental and physical health in later life. Less social support, smaller social networks, and more negative social interactions have been linked to depression, poorer immune functioning, lower self-rated health, increased incidence of disease, and higher mortality. Overwhelming evidence suggests that communication disorders adversely affect social relationships. Much less is known about whether some or all aspects of social relationships are negatively affected by a communication disorder. The relative impact of a communication disorder on social relationships, as compared to other kinds of disability, is also poorly understood. Data were analyzed from a representative national sample of community-dwelling adults aged 65 and older living in the continental United States (n = 742). Results from multiple regressions indicated that difficulty communicating was significantly associated with several parameters of social relationships even after controlling for age, gender, partnership status, health, functional limitations, and visual impairment. Communication difficulty was a significant predictor of smaller social network size, fewer positive social exchanges, less frequent participation in social activities, and higher levels of loneliness, but was not a significant predictor of negative social exchanges. These findings suggest that communication disorders may place older adults at increased risk for mental and physical health problems because of social isolation, reduced social participation, and higher rates of loneliness. In addition, it appears that communication disorders may have a greater impact on positive, rather than negative, aspects of social relationships. PMID:27420152

High water availability increases the negative impact of a native hemiparasite on its non-native host

Environmental factors alter the impacts of parasitic plants on their hosts. However, there have been no controlled studies on how water availability modulates stem hemiparasites’ effects on hosts. A glasshouse experiment was conducted to investigate the association between the Australian native stem hemiparasite Cassytha pubescens and the introduced host Ulex europaeus under high (HW) and low (LW) water supply. Cassytha pubescens had a significant, negative effect on the total biomass of U. europaeus, which was more severe in HW than LW. Regardless of watering treatment, infection significantly decreased shoot and root biomass, nodule biomass, nodule biomass per unit root biomass, F v/F m, and nitrogen concentration of U. europaeus. Host spine sodium concentration significantly increased in response to infection in LW but not HW conditions. Host water potential was significantly higher in HW than in LW, which may have allowed the parasite to maintain higher stomatal conductances in HW. In support of this, the δ13C of the parasite was significantly lower in HW than in LW (and significantly higher than the host). C. pubescens also had significantly higher F v/F m and 66% higher biomass per unit host in the HW compared with the LW treatment. The data suggest that the enhanced performance of C. pubescens in HW resulted in higher parasite growth rates and thus a larger demand for resources from the host, leading to poorer host performance in HW compared with LW. C. pubescens should more negatively affect U. europaeus growth under wet conditions rather than under dry conditions in the field. PMID:26703920

Although there is some evidence to support an association between exposure to televised tobacco control campaigns and recall among youth, little research has been conducted among adults. In addition, no previous work has directly compared the impact of different types of emotive campaign content. The present study examined the impact of increased exposure to tobacco control advertising with different types of emotive content on rates and durations of self-reported recall. Data on recall of televised campaigns from 1,968 adult smokers residing in England through four waves of the International Tobacco Control (ITC) United Kingdom Survey from 2005 to 2009 were merged with estimates of per capita exposure to government-run televised tobacco control advertising (measured in GRPs, or Gross Rating Points), which were categorised as either "positive" or "negative" according to their emotional content. Increased overall campaign exposure was found to significantly increase probability of recall. For every additional 1,000 GRPs of per capita exposure to negative emotive campaigns in the six months prior to survey, there was a 41% increase in likelihood of recall (OR = 1.41, 95% CI: 1.24-1.61), while positive campaigns had no significant effect. Increased exposure to negative campaigns in both the 1-3 months and 4-6 month periods before survey was positively associated with recall. Increased per capita exposure to negative emotive campaigns had a greater effect on campaign recall than positive campaigns, and was positively associated with increased recall even when the exposure had occurred more than three months previously.

Purpose Racial disparity in breast cancer outcomes exists between African American and Caucasian women in the United States. We have evaluated the impact of genetically determined ancestry on disparity in efficacy and therapy-induced toxicity for breast cancer patients in the context of a randomized, phase III adjuvant trial. Patients and Methods This study compared outcomes between 386 patients of African ancestry (AA) and 2473 patients of European ancestry (EA) in a randomized, phase III breast cancer trial; ECOG-ACRIN-E5103. The primary efficacy endpoint, invasive disease free survival (DFS) and clinically significant toxicities were compared including: anthracycline-induced congestive heart failure (CHF), taxane-induced peripheral neuropathy (TIPN), and bevacizumab-induced hypertension. Results Overall, AAs had significantly inferior DFS (p=0.002; HR=1.5) compared with EAs. This was significant in the estrogen receptor-positive subgroup (p=0.03); with a similar, non-significant trend for those who had triple negative breast cancer (TNBC; p=0.12). AAs also had significantly more grade 3-4 TIPN (OR=2.9; p=2.4 ×10-11) and grade 3-4 bevacizumab-induced hypertension (OR=1.6; p=0.02), with a trend for more CHF (OR=1.8; p=0.08). AAs had significantly more dose reductions for paclitaxel (p=6.6 ×10-6). In AAs, dose reductions in paclitaxel had a significant negative impact on DFS (p=0.03); whereas in EAs, dose reductions did not impact outcome (p=0.35). Conclusion AAs had inferior DFS with more clinically important toxicities in ECOG-ACRIN-E5103. The altered risk to benefit ratio for adjuvant breast cancer chemotherapy should lead to additional research with the focus centered on the impact of genetic ancestry on both efficacy and toxicity. Strategies to minimize dose reductions for paclitaxel, especially due to TIPN, are warranted for this population. PMID:29333527

To assess the impact of socio-demographic and comorbidity factors, and quantified depressive symptoms on disability in inpatients. Observational cross-sectional study, including a number of 80 elderly (16 men, 64 women; mean age 72.48 years; standard deviation 9.95 years) admitted in the Geriatrics Clinic of "St. Luca" Hospital, Bucharest, between May-July, 2012. We used the Functional Independence Measure, Geriatric Depression Scale and an array of socio-demographic and poly-pathology parameters. Statistical analysis included Wilcoxon and Kruskal-Wallis tests for ordinal variables, linear bivariate correlations, general linear model analysis, ANOVA. FIM scores were negatively correlated with age (R=-0.301; 95%CI=-0.439 -0.163; p=0.007); GDS scores had a statistically significant negative correlation (R=-0.322; 95% CI=-0.324 -0.052; p=0.004) with FIM scores. A general linear model, including other variables (gender, age, provenance, matrimonial state, living conditions, education, respectively number of chronic illnesses) as factors, found living conditions (p=0.027) and the combination of matrimonial state and gender (p=0.004) to significantly influence FIM scores. ANOVA showed significant differences in FIM scores stratified by the number of chronic diseases (p=0.035). Our study objectified the negative impact of depression on functional status; interestingly, education had no influence on FIM scores; living conditions and a combination of matrimonial state and gender had an important impact: patients with living spouses showed better functional scores than divorced/widowers; the number of chronic diseases also affected the FIM scores: lower in patients with significant polypathology. These findings should be considered when designing geriatric rehabilitation programs, especially for home--including skilled--cares.

Food impaction and periodontal/peri-implant tissue conditions were evaluated in relation to the embrasure dimensions between implant-supported fixed dental prostheses (FDPs) and adjacent teeth. A total of 215 embrasures of 150 FDPs in 100 patients (55 males and 45 females, aged 27 to 83 years; mean age: 56 years) were included in the study. Clinical assessments of the periodontal/peri-implant mucosal conditions, radiographic assessments of embrasure dimensions, and overall patient satisfaction were used as explanatory variables for the food impaction and periodontal/peri-implant tissue conditions adjacent to implant-supported FDPs in the generalized estimating equation (GEE) analysis. Food impaction was reported in 96 (44.7%) of 215 embrasures between implant-supported FDPs and adjacent teeth. Food impaction was reported more frequently in the embrasures with proximal contact loss than in those with tight contact (P = 0.009). Overall patient satisfaction was influenced negatively by food impaction in the proximal embrasures (P = 0.01). Among embrasure dimensions, only the embrasure surface area (ESA) significantly influenced food impaction (P = 0.03). Significant influences of various embrasure dimensions on the periodontal/peri-implant mucosal conditions and bone level at the implant were found in the univariate and multivariate GEE analyses. Food impaction between implant-supported FDPs and adjacent teeth occurred more frequently when proximal contact was lost and ESA increased. Food impaction negatively affected overall patient satisfaction. Embrasure dimensions influenced the periodontal/peri-implant mucosal conditions and bone level at the implant.

To investigate the impact of emotional maltreatment on self-esteem among adolescents, and to see if gender makes a difference in this context. The cross-sectional study was conducted from January to April 2014, and comprised adolescents in the age range of 14 to 18 years who were selected using purposive sampling from various government and private schools and colleges of Sargodha, Punjab. The questionnaire on seven dimensions of emotional maltreatment at home and Rosenberg self-esteem scale were used. There were 400 subjects; 200(50%) boys and as many girls. The overall mean age was 16.14±1.36 years (range: 14-18 years). Correlation coefficient indicated significant negative relationship between emotional maltreatment and self-esteem (degrading r= -0.33, p<0.01; exploitation r= -0.30, p< 0.01; isolating r=-0.36, p<0.01; ignoring r= -0.32, p<0.01; rejecting r=-0.43, p< 0.01; and terrorizing r= -0.35, p<0.01) among students. Emotional maltreatment strongly predicted negative self-esteem (isolating?= -0.12, p<0.05; and rejecting ?= -0.30, p< 0.001) among adolescents. Findings indicated significant gender differences in degrading component of emotional maltreatment and self-esteem. Emotional maltreatment strongly predicted negative self-esteem among adolescents. Gender was a significant factor in the domain of degrading.

The development of open pit mining in the large coal basins of Russia and other countries increases their negative impact on the environment. Along with the damage of land and air pollution by dust and combustion gases of blasting, coal pits have a significant negative impact on water resources. Polluted quarry water worsens the ecological situation on a much larger area than covered by air pollution and land damage. This significantly worsens the conditions of people living in cities and towns located near the coal pits, and complicates the subsequent restoration of the environment, irreversibly destroying the nature. Therefore, the research of quarry wastewater purifying is becoming an important mater for scholars of technical colleges and universities in the regions with developing open-pit mining. This paper describes the method of determining the basic parameters of the artificial filtering arrays formed on coal pits of Kuzbass (Western Siberia, Russia), and gives recommendations on its application.

Natural disasters such as tsunami, hurricanes, and earthquakes may have a negative impact on cardiac health. The aim of our systematic review is to evaluate the impact of earthquakes on the incidence of acute coronary syndromes and cardiac mortality and to examine the impact of the time of earthquakes on the incidence of acute coronary syndromes. MEDLINE and Cochrane databases were searched for studies assessing the impact of earthquakes on acute coronary syndromes from inception until December 20, 2017. Reference lists of all included studies and relevant review studies were also searched. A total of 26 studies on 12 earthquake disasters were included in the systematic review. The existing data show a significant negative impact of the Great East Japan, Christchurch, Niigata-Chuetsu, Northridge, Great Hanshin-Awaji, Sichuan, Athens, Armenia, and Noto Peninsula earthquakes on the incidence of acute coronary syndromes. By contrast, studies on the Newcastle, Loma Prieta, and Thessaloniki earthquakes did not show a significant correlation with myocardial infarction and cardiac mortality. In conclusion, earthquakes may be associated with increased incidence of acute coronary syndromes and cardiovascular mortality. There are conflicting data about the impact of the timing of earthquakes on the occurrence of acute coronary syndromes. Preventive measures to promote the adjustment of healthcare systems to treat cardiovascular diseases after natural disasters should be immediately implemented particularly in high-risk regions.

Recently, epidemiologic studies of developmental neurotoxicology have been challenged to increase focus on co-exposure to multiple toxicants. Earlier reports, including our own work in Bangladesh, have demonstrated independent associations between neurobehavioral function and exposure to both arsenic (As) and manganese (Mn) in school-aged children. Our earlier studies, however, were not designed to examine possible interactive effects of exposure to both As and Mn. To allow investigation of possible synergistic impact of simultaneous exposures, we recruited a new sample of 299 8-11 year old children, stratified by design on As (above and below 10 μg/L) and Mn (above and below 500 μg/L) concentrations of household wells. When adjusted only for each other, both As and Mn in whole blood (BAs; BMn) were significantly negatively related to most WISC-IV subscale scores. With further adjustment for socio-demographic features and ferritin, BMn remained significantly associated with reduced Perceptual Reasoning and Working Memory scores; associations for BAs, and for other subscales, were expectably negative, significantly for Verbal Comprehension. Urinary As (per gram creatinine) was significantly negatively associated with Verbal Comprehension scores, even with adjustment for BMn and other contributors. Mn by As interactions were not significant in adjusted or unadjusted models (all p's>0.25). Findings are consistent with other reports documenting adverse impact of both As and Mn exposure on child developmental outcomes, although associations appear muted at these relatively low exposure levels.

HIV/AIDS has become a full-blown development crisis affecting all sectors of the economy in most developing countries. Its social and economic consequences are felt widely not only in health but in education, industry, agriculture as well as transport. The study attempted to estimate the changes in worker's output and attendance associated with advancing HIV infection, and direct costs incurred by a fiber products factory due to illness and death related to HIV/AIDS. The study is a retrospective cohort with accounting method of cost estimation. The study subjects were factory workers enrolled in a cohort study of HIV incidence and progression in Akaki, Ethiopia since February 1997. The mean incentive earnings were not significantly different between HIV positives and negatives at baseline (in 1997). However, in the following years (1998, 1999 and 2000) the incentive earnings of HIV positives were significantly lower than the incentive earnings of HIV negatives. Trend analysis showed that advancing HIV infection, as measured by drop in CD4 count and increasing viral load, is associated with reduction in productivity and increased sick leave days. The study has shown that there is a direct negative impact of HIV infection on the productivity of factory workers and recommends institution of ART centers and programs in work places to mitigate the socio economic impact of the pandemic.

Rheumatoid arthritis is a common disabling form of arthritis that frequently affects the hands and feet. With time, the majority of affected individuals will become disabled. Sixty-nine consecutively selected mild to moderately affected individuals with rheumatoid arthritis provided demographic data and agreed to complete the Short Musculoskeletal Function Assessment (SFMA) instrument. Focus group subjects selectively used minimally adaptive nonprescription footwear. Control subjects had similar disease expression, but did not alter their choice of footwear due to their disease. Adult patients with rheumatoid arthritis demonstrate a significant negative impact on their quality of life with mild or moderate disease expression, as evidenced by poor scores in all six domains of the SFMA. Subjects who used even mildly adaptive nonprescription footwear demonstrated a statistically significant negative impact in mobility (p < .044) and functional index (p < .052) domains as compared with the control population having similar overall disease expression. Focus subjects also demonstrated a trend to less favorable scores in the arm and hand domain. Mean scores of the daily activity, emotional status, and bother index domains fared worse than population norms, but there was no statistical difference between subjects using, or not using, adaptive footwear. Individuals affected with mild to moderate rheumatoid arthritis are disabled as compared with the general population. There is a severe negative impact on mobility and functional capacity when the disease process begins to affect their feet.

At present, a significant amount of energy spent for the work of mining machines and coal mining equipment on coal mines and open pits goes to the coal grinding in the process of its extraction in mining faces. Meanwhile, the increase of small fractions in mined coal does not only reduce the profitability of its production, but also causes a further negative impact on the environment and degrades labor conditions for miners. The countermeasure to the specified processes is possible with the help of coal mining equipment development. However, against the background of the technological decrease of coal mine equipment applied in Russia the negative impact on the environment is getting reinforced.

While most crisis intervention models adhere to a generalised theoretical framework, the lack of clarity around how these should be enacted has resulted in a proliferation of models, most of which have little to no empirical support. The primary aim of this research was to propose a suicide intervention model that would resolve the client's suicidal crisis by decreasing their suicidal ideation and improve their outlook through enhancing a range of protective factors. The secondary aim was to assess the impact of this model on negative and positive outlook. A quasi-experimental, pre-test post-test repeated measures design was employed. A questionnaire assessing self-esteem, depression, and positive and negative suicidal ideation was administered to the same participants pre- and post- therapy facilitating paired responses. Multiple analysis of variance and paired-samples t-tests were conducted to establish whether therapy using the PH-SIM had a significant effect on the clients' negative and positive outlook. Analyses revealed a statistically significant effect of therapy for depression, negative suicidal ideation, self-esteem, and positive suicidal ideation. Negative outlook was significantly lower after therapy and positive outlook significantly higher. The decreased negative outlook and increased positive outlook following therapy provide some support for the proposed model in fulfilling its role, though additional research is required to establish the precise role of the intervention model in achieving this.

2017-07-01

The effects of high pressure processing (HPP; 600MPa for 3min at 8°C) on the quality and shelf life of reduced sodium naturally-cured wieners was studied. HPP did not negatively impact processing characteristics and assisted in extending shelf life of all wiener treatments up to a 12week storage period. At week 8, HPP wieners received higher acceptability scores, indicating HPP can effectively extend the sensory quality of products, including sodium reduced formulations containing natural forms of nitrite. Substitution of 50% NaCl with modified KCl had negative effect on textural characteristics of conventionally cured wieners but not those processed with celery powder as a source of nitrite. Celery powder favorably affected hydration of textural properties of wieners, and consumer acceptability of juiciness and texture was higher compared to nitrite. Sodium reduction, independent of curing agent, negatively impacted flavor acceptability, while only nitrite containing reduced sodium wieners scored significantly lower than both regular salt wieners for texture, juiciness and saltiness.

2010-03-01

Mothers' cognitive appraisal of the family impact of childhood disability and their positive affect as a psychological coping resource, both key elements of the process model of stress and coping, were tested as explanatory variables of family adjustment. In a sample of Canadian families, 195 mothers of children with intellectual and developmental disability completed telephone interviews. In regression modelling, 35% of the variance in family adjustment was explained by mothers' positive cognitive appraisal of family impacts of childhood disability and by their positivity (ratio of positive to negative affect). After controlling for positivity, negative cognitive appraisal of family impacts of childhood disability was non-significant. Family adjustment to childhood disability is associated with elements of strength in mothers' psychological coping; namely, their ability to perceive positive family consequences of childhood disability and to maintain higher proportions of positive emotion in their daily activities. The findings of this study provide support for the broaden-and-build theory to explain the role of positivity in mothers' coping and adjustment to childhood disability.

It is widely recognized that emotions impact an individual's ability to perform in a given task. However, little is known about how emotion impacts the various aspects of cognitive -motor performance. We recorded event-related potentials (ERPs) and chronometric responses from twenty-six participants while they performed a cognitive-motor oddball task in regard to four categories of emotional stimuli (high-arousing positive-valence, low-arousing positive-valence, high-arousing negative-valence, and low-arousing negative-valence) as "deviant" stimuli. Six chronometric responses (reaction time, press time, return time, choice time, movement time, and total time) and three ERP components (P2, N2 and late positive potential) were measured. Results indicated that reaction time was significantly affected by the presentation of emotional stimuli. Also observed was a negative relationship between N2 amplitude and elements of performance featuring reaction time in the low-arousing positive-valence condition. This study provides further evidence that emotional stimuli influence cognitive-motor performance in a specific manner. Copyright © 2017 Elsevier B.V. All rights reserved.

2013-06-01

The study was conducted to extend research on the reluctance for emotional disclosure to Chinese patients with a variety of types of cancer. A quantitative survey was conducted among 400 cancer patients in China. Statistical analysis revealed that among four confirmed factors on reluctance for emotional disclosure to physicians, no perceived need scored highest, followed by unwillingness to bother, no practical use, and fear of negative impact. Patient distress was negatively associated with no perceived need and no practical use. Patients with low family support scored significantly lower in all factors except fear of negative impact. Education and income affected the factor of no perceived need. Those patients having limited family support and limited education indicated a higher need for emotional support from their physicians and were more likely to open up to them. Cultural traits should be integrated into supportive cancer care research.

Abstract To assess the self-esteem of pediatric patients on chemotherapy for acute lymphoblastic leukemia (ALL) and psychological status of their parents. The psychological status of 178 children receiving chemotherapy for ALL and their parents was assessed using parenting stress index (PSI) to determine the degree of stress the parents are exposed to using parent's and child's domains. Self-esteem Scale was used to determine the psychological status of patients. The study revealed significant low level of self-esteem in 84.83% of patients. Their parents had significant psychological stress. PSI was significantly associated with parents’ low sense of competence, negative attachment to their children, feeling of high restriction, high depression, poor relation to spouse, high social isolation variables of parent's domains. It was significantly associated with low distraction, negative parents’ reinforcement, low acceptability, and high demanding variables of child's domains. Long duration of disease was the most detrimental factor among demographic data of the patients. Chemotherapy for ALL has a significant impact on the psychological status of both patients and their parents with high prevalence of low self-esteem in children and high degree of stress in their parents.

Dams on a river are believed to have heterogeneous impacts to the upstream, local and downstream areas. Generally, irrigation dams will bring benefits to the downstream by facilitating more irrigation, while it will bring negative impacts to upstream due to inundation or no impact to local area as a combination result of population dislocation and economic benefits. This paper checked the impacts of large dams (above 100 meters) on the upstream, downstream and local area, using 2000-2008 county level data in China. Robust heterogeneous impacts of different categories of dams (mainly dams serving for irrigation, hydropower, or other purposes) were found on different areas, using IV regression approaches. Dams higher than 100 meters are significantly and heterogeneously impacting agricultural production, urban employment and rural per capita income. Its beneficial impact on agriculture production is significant for downstream especially in continuous drought years. But its impacts on social welfare indicators, such as primary school enrollment and hospital beds, are not heterogeneously different across regions.

Federal Law no. 219-FZ of July 21, 2014, "On the Amendments to the Federal Law On Environmental Protection and Certain Legislative Acts" of the Russian Federation established new principles of environmental policy aimed at significantly reducing the negative anthropogenic impact on the environment. Currently, active work is under way to harmonize the Russian environmental legislation with regard to the transition to a system of technological regulation of impacts using the best available technologies (BATs). A national regulatory system based on BATs can be developed only through the implementation of integrated measures that are adopted and regulated at different levels (from decisions of the government of the Russian Federation to normative documents). For this purpose, more than 50 sectoral information and technical reference books on BATs have been developed that include descriptions of BATs for particular types of activities and their technological indicators. Starting on January 1, 2019, an integrated environmental permit will be introduced for enterprises with the greatest negative impact on the environment (category I enterprises). In addition, these enterprises will have to implement automatic systems for continuous control and metering of contaminants emissions (ASCCMCEs) into the atmosphere. Therefore, the development and adoption of the preliminary national standard of the Russian Federation PNS 187-2017, which is to come into force on January 1, 2018, will significantly accelerate and facilitate the implementation of ASCCMCEs of thermal power plants (TPPs) in accordance with Federal Law no. 219-FZ. The main goal of implementing ASCCMCEs on TPPs is to consistently reduce the negative impact of thermal power plants on the environment.

Macroeconomics of Natural Disasters: Strengths and Weaknesses of Meta-Analysis Versus Review of Literature.

2015-06-01

We use the case of the macroeconomic impact of natural disasters to analyze strengths and weaknesses of meta-analysis in an emerging research field. Macroeconomists have published on this issue since 2002 (we identified 60 studies to date). The results of the studies are contradictory and therefore the need to synthesize the available research is evident. Meta-analysis is a useful method in this field. An important aim of our article is to show how one can use the identified methodological characteristics to better understand the robustness and importance of new findings. To provide a comparative perspective, we contrast our meta-analysis and its findings with the major influential research synthesis in the field: the IPCC's 2012 special report Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation. We show that the IPCC could have been more confident about the negative economic impact of disasters and more transparent on inclusion and qualification of studies, if it had been complemented by a meta-analysis. Our meta-analysis shows that, controlling for modeling strategies and data set, the impact of disasters is significantly negative. The evidence is strongest for direct costs studies where we see no difference between our larger sample and the studies included in the IPCC report. Direct cost studies and indirect cost studies differ significantly, both in terms of the confidence that can be attached to a negative impact of natural disasters and in terms of the sources of heterogeneity of the findings reported in the primary studies. © 2015 Society for Risk Analysis.

The costly burden of an inauthentic self: insecure self-esteem predisposes to emotional exhaustion by increasing reactivity to negative events.

A long research tradition has investigated the impact of stress on university students by assuming that individuals have a limited reservoir of resources, and that negative events and circumstances progressively drain resources thereby producing exhaustion. A recent research tradition, instead, has focused on the detrimental consequences of discrepant levels of implicit (ISE) and explicit (ESE) self-esteem on the development of stress-related symptoms. The present research attempted to merge the aforementioned approaches, with the aim of explaining significant predictors of stress. Within the framework of a Longitudinal Structural Equation Model, we followed a moderated-mediated approach. A sample of university students (N = 209; 66% females) completed a questionnaire battery including measures of ISE, ESE, perceptions of negative events, and emotional exhaustion. Participants were assessed once a week for eight consecutive weeks. ISE significantly moderated the relationship between ESE and negative events; in turn, the latter significantly predicted emotional exhaustion. Monte Carlo method for assessing mediation showed that negative events significantly mediated the relationship between incongruent self-esteem and emotional exhaustion. The detrimental role of incongruent self-esteem has been corroborated. Practical implications and suggestions for future research dealing with stress in a university setting were provided.

Poor problem-solving and low self-esteem are frequently cited as significant factors in the development and maintenance of anorexia nervosa. The current study examines the multi-dimensional elements of these measures and postulates a model whereby self-esteem mediates the relationship between social problems-solving and anorexic pathology and considers the implications of this pathway. Fifty-five inpatients with a diagnosis of anorexia nervosa and 50 non-clinical controls completed three standardised multi-dimensional questionnaires pertaining to social problem-solving, self-esteem and eating pathology. Significant differences were yielded between clinical and non-clinical samples on all measures. Within the clinical group, elements of social problem-solving most significant to anorexic pathology were positive problem orientation, negative problem orientation and avoidance. Components of self-esteem most significant to anorexic pathology were eating, weight and shape concern but not eating restraint. The mediational model was upheld with social problem-solving impacting on anorexic pathology through the existence of low self-esteem. Problem orientation, that is, the cognitive processes of social problem-solving appear to be more significant than problem-solving methods in individuals with anorexia nervosa. Negative perceptions of eating, weight and shape appear to impact on low self-esteem but level of restriction does not. Finally, results indicate that self-esteem is a significant factor in the development and execution of positive or negative social problem-solving in individuals with anorexia nervosa by mediating the relationship between those two variables.

BACKGROUND The Management of Myelomeningocele Study (MOMS) was a multicenter, randomized controlled trial that compared prenatal repair with standard postnatal repair for fetal myelomeningocele. OBJECTIVE We sought to describe the long-term impact on the families of the women who participated and to evaluate how the timing of repair influenced the impact on families and parental stress. STUDY DESIGN Randomized women completed the 24-item Impact on Family Scale (IFS) and the 36-item Parenting Stress Index Short Form (PSI-SF) at 12 and 30 months after delivery. A revised 15-item score of the IFS (RIFS) describing overall impact was also computed. Higher scores reflect more negative impacts or greater stress. In addition, we examined Family Support Scale (FSS) and Family Resource Scale (FRS) scores along with various neonatal outcomes. Repeated measures analysis was conducted for each scale and subscale. RESULTS Of 183 women randomized, 171 women completed the IFS and 172 completed the PSI at both 12 and 30 months. The prenatal surgery group had significantly lower RIFS scores as well as familial-social impact subscale scores compared to the postnatal surgery group (p=0.02 and 0.004, respectively). There was no difference in total parental stress between the two groups (p=0.89) or in any of the PSI-SF subscales. In addition, walking independently at 30 months and family resources at 12 months are associated with both family impact and parental stress. CONCLUSION The overall negative family impact of caring for a child with spina bifida, up to 30 months of age, was significantly lower in the prenatal surgery group compared to the postnatal surgery group. Ambulation status and family resources were predictive of impact on family and parental stress. PMID:27263997

To assess current procedures of processing positive blood cultures against national standards with an aim to evaluate its clinical impact and to determine the utility of currently available rapid identification and susceptibility tests in processing of blood cultures. Blood cultures from three secondary care hospitals, processed at a centralised laboratory, were prospectively audited. Data regarding processing times, communication with prescribers, changes to patient management and mortality within 30 days of a significant blood culture were collected in a preplanned pro forma for a 4-week period. Of 2206 blood cultures, 211 positive blood cultures flagged positive. Sixty-nine (3.1%) of all cultures were considered to be contaminated. Fifty per cent of blood cultures that flagged positive had a Gram stain reported within 2 hours. Two (0.99%) patients with a significant bacteraemia had escalation of antimicrobial treatment at the point of reporting the Gram stain that was subsequently deemed necessary once sensitivity results were known. Most common intervention was de-escalation of therapy for Gram-positive organisms at the point of availability of pathogen identification (25.6% in Gram positive vs 10% in Gram negative; p=0.012). For Gram-negative organisms, the most common intervention was de-escalation of therapy at the point of availability of sensitivity results (43% in Gram negatives vs 17.9% in Gram positive; p=0.0097). Overall mortality within 30 days of a positive blood culture was 10.9% (23/211). Antibiotic resistance may have contributed to mortality in four of these patients (three Gram negative and one Gram positive). Gram stain result had the least impact on antibiotic treatment interventions (escalation or de-escalation). Tests that improve identification time for Gram-positive pathogens and sensitivity time for Gram-negative pathogens had the greatest impact in making significant changes to antimicrobial treatment.

Although Rift Valley fever (RVF) has significant impacts on human health and livestock production, it can also induce significant (and often overlooked) economic losses among various stakeholders in the marketing chain. This work assesses and quantifies the multi-dimensional socio-economic impacts of the 2007 RVF outbreak in Kenya based on a rapid assessment of livestock value chains in the northeast part of the country and a national macroeconomic analysis. Although study results show negative impacts among producers in terms of food insecurity and reductions in income, we also found significant losses among other downstream actors in the value chain, including livestock traders, slaughterhouses, casual laborers, and butchers, as well as other, non-agricultural sectors. The study highlights the need for greater sensitivity and analyses that address the multitude of economic losses resulting from an animal disease to better inform policy and decision making during animal health emergencies.

This study aimed to evaluate the impact of comorbid attention deficit hyperkinetic disorder (ADHD) on Bipolar disorder (BD). Patients aged 13-40 years with diagnosis of BD with ADHD (N = 30) were compared to those with BD without ADHD (N = 69) for clinical course, functional outcome and quality of life. Those with BD + ADHD had significantly lower age of onset of BD (p < 0.001), a significantly higher number of total lifetime episodes (p = 0.002), higher number of lifetime manic episodes (p = 0.008), higher number of hospitalizations (p = 0.004) and higher prevalence of family history of BD as compared to those with BD without ADHD (p = 0.043). BD + ADHD group had poor response to conventional mood stabilizers and significantly higher prescriptions of atypical antipsychotics (p = 0.001) and higher rates of antidepressant-induced switch. Also, BD + ADHD group had significantly lower level of functioning in personal, occupational and social domains and reduced quality of life. In the BD + ADHD group, 40% patients had persistence of ADHD into adulthood. Comorbid current ADHD had more negative impact on the course and outcome of BD, when compared with those with ADHD in the past. Comorbid ADHD has negative impact on the course and outcome of BD.

The buffer value of groundwater when well yield is limited

Foster, T.; Brozović, N.; Speir, C.

2017-04-01

A large proportion of the total value of groundwater in conjunctive use systems is associated with the ability to smooth out shortfalls in surface water supply during droughts. Previous research has argued that aquifer depletion in these regions will impact farmers negatively by reducing the available stock of groundwater to buffer production in future periods, and also by increasing the costs of groundwater extraction. However, existing studies have not considered how depletion may impact the productivity of groundwater stocks in conjunctive use systems through reductions in well yields. In this work, we develop a hydro-economic modeling framework to quantify the effects of changes in well yields on the buffer value of groundwater, and apply this model to an illustrative case study of tomato production in California's Central Valley. Our findings demonstrate that farmers with low well yields are forced to forgo significant production and profits because instantaneous groundwater supply is insufficient to buffer surface water shortfalls in drought years. Negative economic impacts of low well yields are an increasing function of surface water variability, and are also greatest for farmers operating less efficient irrigation systems. These results indicate that impacts of well yield reductions on the productivity of groundwater are an important economic impact of aquifer depletion, and that failure to consider this feedback may lead to significant errors in estimates of the value of groundwater management in conjunctive use systems.

Objectives Our objective is to explore how vasculitis, affects patients’ friendships and social participation. Methods Vasculitis patients (n=221) completed an online questionnaire that asked if, and how, relationships with friends have changed since receiving a vasculitis diagnosis. Participants’ written responses were imported into Atlas.ti, and two independent researchers used both structured and unstructured coding to identify themes. After reaching 100% consensus on the themes present in each participant’s responses, the coders determined how themes were interrelated across participants. Results Over half of patients (52%) expressed that vasculitis negatively impacted their friendships and 25% noted a negative impact on their social participation. At limes, this negative impact was related to structural changes in patients’ social networks due to loss of friendships. Reduced social participation was also associated with friends’ inability to understand vasculitis and its effects, vasculitis-related fatigue, and lifestyle changes such as not being able to drink alcohol and avoiding infection-prone events. Additionally, patients withdrew from social engagements due to fatigue or because of physical symptoms and side effects. Conclusion The unique circumstances associated with a rare chronic illness like vasculitis can create significant barriers to friendships, including loss of these relationships. Interventions designed to help patients cope with the social impact of vasculitis are implicated, especially if they increase patients’ ability to engage in dialogue about their illness with their friends.

The seafloor at an open ocean finfish aquaculture facility in the western Gulf of Maine, USA was monitored from 1999 to 2008 by sampling sites inside a predicted impact area modeled by oceanographic conditions and fecal and food settling characteristics, and nearby reference sites. Univariate and multivariate analyses of benthic community measures from box core samples indicated minimal or no significant differences between impact and reference areas. These findings resulted in development of an adaptive monitoring protocol involving initial low-cost methods that required more intensive and costly efforts only when negative impacts were initially indicated. The continued growth of marine aquaculture is dependent on further development of farming methods that minimize negative environmental impacts, as well as effective monitoring protocols. Adaptive monitoring protocols, such as the one described herein, coupled with mathematical modeling approaches, have the potential to provide effective protection of the environment while minimize monitoring effort and costs.

Mind-body medicine: stress and its impact on overall health and longevity.

2005-12-01

The belief that adverse life stressors and the emotional states that can lead to major negative impacts on an individual's body functions and hence health has been held since antiquity. Adverse health outcomes such as coronary heart disease, gastrointestinal distress, and cancer have been linked to unresolved lifestyle stresses that can be expressed as a negative impact on human survival and ultimately a decrease of the human life span. Psychological modulation of immune function is now a well-established phenomenon, with much of the relevant literature published within the last 50 years. Psychoneuroimmunology and psychoneuroendocrinology embrace the scientific evidence of research of the mind with that of endocrinology, neurology and immunology, whereby the brain and body communicate with each other in a multidirectional flow of information that consists of hormones, neurotransmitters/neuropeptides, and cytokines. Advances in mind-body medicine research together with healthy nutrition and lifestyle choices can have a significant impact on health maintenance and disease prevention and hence the prolongation of the human life span.

Menopause is an important life event that may have a negative influence on quality of life. Work ability, a concept widely used in occupational health, can predict both future impairment and duration of sickness absence. The aim of this study was to examine the impact of menopausal symptoms on work ability. This was a cross-sectional study that used a sample of healthy working Dutch women aged 44 to 60 years. Work ability was measured using the Work Ability Index, and menopausal symptoms were measured using the Greene Climacteric Scale. Stepwise multiple linear regression models were used to examine the relationship between menopausal symptoms and work ability. A total of 208 women were included in this study. There was a significant negative correlation between total Greene Climacteric Scale score and Work Ability Index score. Total Greene Climacteric Scale score predicted 33.8% of the total variance in the Work Ability Index score. Only the psychological and somatic subscales of the Greene Climacteric Scale were significant predictors in multiple linear regression analysis. Together, they accounted for 36.5% of total variance in Work Ability Index score. Menopausal symptoms are negatively associated with work ability and may increase the risk of sickness absence.

Aim: To assess the impact of vocational rehabilitation on psychopathology, social functioning and cognitive functioning in schizophrenia Materials and Methods: 34 patients with DSM IV diagnosis of chronic schizophrenia were compared 40 patients with same diagnosis but not attending vocational rehabilitation using PANSS, SCARF social functioning Index and MMSE. Results and Discussion: Basic psycho-socio-demographic data were comparable in both groups except more hospitalization in the no rehabilitation group. Comparison of social functioning, cognitive functioning and psychopathology showed significant improvement in rehabilitated patients. Cognitive functioning had positive correlation with occupational role in the rehabilitated group and negative correlation in the rehabilitated group. Social functioning had negative correlation with positive and negative symptoms, general psychopathology and total PANSS score and cognitive symptoms in patients without rehabilitation. Conclusion: The present concludes that there is a definite limitation in the domains of social functioning, cognitive functioning and psychopathology in chronic schizophrenia patients who had no rehabilitation. However vocational rehabilitation significantly improves these limitations, which in turn help these patients to integrate into the society so as to function efficiently in their roles as parents, home makers and social beings.

Adverse social circumstances during one's life course have been related to an increased risk of mortality. This article extends the literature by focusing on adversity at each phase of, and cumulatively at midlife in the Swedish population. Data on socioeconomic indicators from 1970, 1980 and 1990 were linked to death registrations from 2000 to 2009. Relative indices of inequalities were computed for socioeconomic indicators, in order to measure the cumulative impact of inequality on mortality. A significant cumulative effect of being in the worst-off socioeconomic groups was found. For men, almost all indicators had a significant independent impact on risk of death. Among women, significant independent impacts were found for education in 1990 and for socioeconomic index in the 2 census years of 1970 and 1980. Being disadvantaged during a longer period in midlife has a significant negative impact on health. Policies targeted to reduce health inequality should focus on every stage of the midlife course.

To estimate the impact of (particularly long-term) unemployment on the overall and mental health of the Spanish working-age population and to check whether the effects of unemployment on health have increased or been tempered as a consequence of the economic crisis. We apply a matching technique to cross-sectional microdata from the Spanish Health Survey for the years 2006 and 2011-2012 to estimate the average treatment effect of unemployment on self-assessed health (SAH) in the last year, mental problems in the last year and on the mental health risk in the short term. We also use a differences-in-differences estimation method between the two periods to check if the impact of unemployment on health depends on the economic context. Unemployment has a significant negative impact on both SAH and mental health. This impact is particularly high for the long-term unemployed. With respect to the impact on mental health, negative effects significantly worsen with the economic crisis. For the full model, the changes in effects of long-term unemployment on mental problems and mental health risk are, respectively, 0.35 (CI 0.19-0.50) and 0.20 (CI 0.07-0.34). Anxiety and stress about the future associated with unemployment could have a large impact on individuals' health. It may be necessary to prevent health deterioration in vulnerable groups such as the unemployed, and also to monitor specific health risks that arise in recessions, such as psychological problems.

Understanding less than nothing: children's neural response to negative numbers shifts across age and accuracy.

We examined the brain activity underlying the development of our understanding of negative numbers, which are amounts lacking direct physical counterparts. Children performed a paired comparison task with positive and negative numbers during an fMRI session. As previously shown in adults, both pre-instruction fifth-graders and post-instruction seventh-graders demonstrated typical behavioral and neural distance effects to negative numbers, where response times and parietal and frontal activity increased as comparison distance decreased. We then determined the factors impacting the distance effect in each age group. Behaviorally, the fifth-grader distance effect for negatives was significantly predicted only by positive comparison accuracy, indicating that children who were generally better at working with numbers were better at comparing negatives. In seventh-graders, negative number comparison accuracy significantly predicted their negative number distance effect, indicating that children who were better at working with negative numbers demonstrated a more typical distance effect. Across children, as age increased, the negative number distance effect increased in the bilateral IPS and decreased frontally, indicating a frontoparietal shift consistent with previous numerical development literature. In contrast, as negative comparison task accuracy increased, the parietal distance effect increased in the left IPS and decreased in the right, possibly indicating a change from an approximate understanding of negatives' values to a more exact, precise representation (particularly supported by the left IPS) with increasing expertise. These shifts separately indicate the effects of increasing maturity generally in numeric processing and specifically in negative number understanding.

The current study compared the predicted social and career impact of socially withdrawn and reticent behaviors among participants from Western and East Asian countries. Three hundred sixty-one college students from 5 Western countries and 455 students from 3 East Asian countries read hypothetical vignettes describing socially withdrawn and shy behaviors versus socially outgoing and confident behaviors. Participants then answered questions following each vignette indicating the extent to which they would expect the subject of the vignette to be socially liked and to succeed in their career. Participants also completed measures of their own social anxiety and quality of life. The results indicated significant vignette-by-country interactions in that the difference in perceived social and career impact between shy and outgoing vignettes was smaller among participants from East Asian countries than from Western countries. In addition, significant negative correlations were shown between personal level of shyness and experienced quality of life for participants from both groups of countries, but the size of this relationship was greater for participants from Western than East Asian countries. The results point to the more negative impact of withdrawn and socially reticent behaviors for people from Western countries relative to those from East Asia. Copyright © 2011.

The current study examined multilevel risk factors and developmental assets on longitudinal trajectories of aggressive behavior in a diverse sample of rural adolescents. Using ecological and social capital theories, we explored the impact of positive and negative proximal processes, social capital, and contextual characteristics (i.e., school and neighborhood) on adolescent aggression. Data came from the Rural Adaptation Project, which is a 5-year longitudinal panel study of more than 4,000 middle and high school students from 40 public schools in two rural, low income counties in North Carolina. A three-level HLM model (N = 4,056 at Wave 1, 4,251 at Wave 2, and 4,256 at Wave 3) was estimated to predict factors affecting the change trajectories of aggression. Results indicated that negative proximal processes in the form of parent-adolescent conflict, friend rejection, peer pressure, delinquent friends, and school hassles were significant predictors of aggression. In addition, social capital in the form of ethnic identity, religious orientation, and school satisfaction served as buffers against aggression. Negative proximal processes were more salient predictors than positive proximal processes. School and neighborhood characteristics had a minimal impact on aggression. Overall, rates of aggression did not change significantly over the 3-year study window. Findings highlight the need to intervene in order to decrease negative interactions in the peer and parent domains. © 2015 Wiley Periodicals, Inc.

High water availability increases the negative impact of a native hemiparasite on its non-native host.

Environmental factors alter the impacts of parasitic plants on their hosts. However, there have been no controlled studies on how water availability modulates stem hemiparasites' effects on hosts. A glasshouse experiment was conducted to investigate the association between the Australian native stem hemiparasite Cassytha pubescens and the introduced host Ulex europaeus under high (HW) and low (LW) water supply. Cassytha pubescens had a significant, negative effect on the total biomass of U. europaeus, which was more severe in HW than LW. Regardless of watering treatment, infection significantly decreased shoot and root biomass, nodule biomass, nodule biomass per unit root biomass, F v/F m, and nitrogen concentration of U. europaeus. Host spine sodium concentration significantly increased in response to infection in LW but not HW conditions. Host water potential was significantly higher in HW than in LW, which may have allowed the parasite to maintain higher stomatal conductances in HW. In support of this, the δ(13)C of the parasite was significantly lower in HW than in LW (and significantly higher than the host). C. pubescens also had significantly higher F v/F m and 66% higher biomass per unit host in the HW compared with the LW treatment. The data suggest that the enhanced performance of C. pubescens in HW resulted in higher parasite growth rates and thus a larger demand for resources from the host, leading to poorer host performance in HW compared with LW. C. pubescens should more negatively affect U. europaeus growth under wet conditions rather than under dry conditions in the field. © The Author 2015.

Impact of negation salience and cognitive resources on negation during attitude formation.

PubMed

Boucher, Kathryn L; Rydell, Robert J

2012-10-01

Because of the increased cognitive resources required to process negations, past research has shown that explicit attitude measures are more sensitive to negations than implicit attitude measures. The current work demonstrated that the differential impact of negations on implicit and explicit attitude measures was moderated by (a) the extent to which the negation was made salient and (b) the amount of cognitive resources available during attitude formation. When negations were less visually salient, explicit but not implicit attitude measures reflected the intended valence of the negations. When negations were more visually salient, both explicit and implicit attitude measures reflected the intended valence of the negations, but only when perceivers had ample cognitive resources during encoding. Competing models of negation processing, schema-plus-tag and fusion, were examined to determine how negation salience impacts the processing of negations.

Drivers of climate change impacts on bird communities.

2015-07-01

Climate change is reported to have caused widespread changes to species' populations and ecological communities. Warming has been associated with population declines in long-distance migrants and habitat specialists, and increases in southerly distributed species. However, the specific climatic drivers behind these changes remain undescribed. We analysed annual fluctuations in the abundance of 59 breeding bird species in England over 45 years to test the effect of monthly temperature and precipitation means upon population trends. Strong positive correlations between population growth and both winter and breeding season temperature were identified for resident and short-distance migrants. Lagged correlations between population growth and summer temperature and precipitation identified for the first time a widespread negative impact of hot, dry summer weather. Resident populations appeared to increase following wet autumns. Populations of long-distance migrants were negatively affected by May temperature, consistent with a potential negative effect of phenological mismatch upon breeding success. There was evidence for some nonlinear relationships between monthly weather variables and population growth. Habitat specialists and cold-associated species showed consistently more negative effects of higher temperatures than habitat generalists and southerly distributed species associated with warm temperatures. Results suggest that previously reported changes in community composition represent the accumulated effects of spring and summer warming. Long-term population trends were more significantly correlated with species' sensitivity to temperature than precipitation, suggesting that warming has had a greater impact on population trends than changes in precipitation. Months where there had been the greatest warming were the most influential drivers of long-term change. There was also evidence that species with the greatest sensitivity to extremes of precipitation have tended to decline. Our results provide novel insights about the impact of climate change on bird communities. Significant lagged effects highlight the potential for altered species' interactions to drive observed climate change impacts, although some community changes may have been driven by more immediate responses to warming. In England, resident and short-distance migrant populations have increased in response to climate change, but potentially at the expense of long-distance migrants, habitat specialists and cold-associated species. © 2015 The Authors.

2017-03-01

A qualitative exploratory inquiry was used to understand nurse managers' (NMs') perceptions of their role stressors, coping strategies, and self-health related outcomes as a result of frequent exposure to stressful situations in their role. Strong nursing leadership is required for desirable staff, patient, and organizational outcomes. A stressed NM will negatively influence staff nurse satisfaction and retention, patient outcomes, and organizational performance. Stress can affect NMs' mental and physical heath, leading to job dissatisfaction and turnover. A qualitative exploratory inquiry was conducted using semistructured interviews with 23 NMs and 1 focus group interview. Findings suggest that coping strategies may be inadequate, given the intensity and demands of the manager role, and could negatively impact NMs' long-term health. Senior nurse leaders can significantly impact the health and productivity of NMs by minimizing the adverse effects of role stress and foster a positive work environment.

High intelligence prevents the negative impact of anxiety on working memory.

PubMed

Chuderski, Adam

2015-01-01

Using a large sample and the confirmatory factor analysis, the study investigated the relationships between anxiety, working memory (WM) and (fluid) intelligence. The study showed that the negative impact of anxiety on WM functioning diminishes with increasing intelligence, and that anxiety can significantly affect WM only in people below average intelligence. This effect could not be fully explained by the sheer differences in WM capacity (WMC), suggesting the importance of higher-level cognition in coping with anxiety. Although intelligence moderated the impact of anxiety on WM, it was only weakly related to anxiety. In contrast to previous studies, anxiety explained the substantial amount of WMC variance (17.8%) in less intelligent participants, but none of the variance in more intelligent ones. These results can be explained in terms of either increased motivation of intelligent but anxious people to cope with a WM task, or their ability to compensate decrements in WM.

Data from farmer-managed fields have not been used previously to disentangle the impacts of daily minimum and maximum temperatures and solar radiation on rice yields in tropical/subtropical Asia. We used a multiple regression model to analyze data from 227 intensively managed irrigated rice farms in six important rice-producing countries. The farm-level detail, observed over multiple growing seasons, enabled us to construct farm-specific weather variables, control for unobserved factors that either were unique to each farm but did not vary over time or were common to all farms at a given site but varied by season and year, and obtain more precise estimates by including farm- and site-specific economic variables. Temperature and radiation had statistically significant impacts during both the vegetative and ripening phases of the rice plant. Higher minimum temperature reduced yield, whereas higher maximum temperature raised it; radiation impact varied by growth phase. Combined, these effects imply that yield at most sites would have grown more rapidly during the high-yielding season but less rapidly during the low-yielding season if observed temperature and radiation trends at the end of the 20th century had not occurred, with temperature trends being more influential. Looking ahead, they imply a net negative impact on yield from moderate warming in coming decades. Beyond that, the impact would likely become more negative, because prior research indicates that the impact of maximum temperature becomes negative at higher levels. Diurnal temperature variation must be considered when investigating the impacts of climate change on irrigated rice in Asia. PMID:20696908

Favorable public opinion and support for policies are essential to favor the sustainability of environmental interventions. This study examined public perceptions and support for active living policies associated with implementing a public bicycle share program (PBSP). Two cross-sectional population-based telephone surveys were conducted in 2009 and 2010 among 5011 adults in Montréal, Canada. Difference-in-differences analyses tested the impact of the PBSP on negative perceptions of the impact of the PBSP on the image of the city, road safety, ease of traveling, active transportation, health, and resistance to policies. People living closer to docking stations were less likely to have negative perceptions of the effect of the PBSP on the image of the city (OR = 0.5; 95% CI, 0.4-0.8) and to be resistant to policies (OR = 0.8; 95% CI, 0.6-1.0). The likelihood of perceiving negative effects on road safety increased across time (OR = 1.4; 95% CI, 1.2-1.8). Significant interactions were observed for perceptions of ease of traveling (OR = 0.5; 95% CI, 0.4-0.8), active transportation (OR = 0.6; 95% CI, 0.4-1.0), and health (OR = 0.6; 95% CI, 0.4-0.8): likelihood of negative perceptions decreased across time among people exposed. Findings indicate that negative perceptions were more likely to abate among those living closer to the PBSP.

Reductions in the eligibility requirements and generosity of disability benefits have been introduced in several Organisation for Economic Cooperation and Development (OECD) countries in recent years, on the assumption that this will increase work incentives for people with chronic illness and disabilities. This paper systematically reviews the evidence for this assumption in the context of well-developed welfare systems. Systematic review of all empirical studies from five OECD countries from 1970 to December 2009 investigating the effect of changes in eligibility requirements or level of disability benefits on employment of disabled people. Sixteen studies were identified. Only one of five studies found that relaxed eligibility was significantly associated with a decline in employment. The most robust study found no significant effect. On generosity, eight out of 11 studies reported that benefit levels had a significant negative association with employment. The most robust study demonstrated a small but significant negative association. There was no firm evidence that changes in benefit eligibility requirements affected employment. While there was some evidence indicating that benefit level was negatively associated with employment, there was insufficient evidence of a high enough quality to determine the extent of that effect. Policy makers and researchers need to address the lack of a robust empirical basis for assessing the employment impact of these welfare reforms as well as potentially wider poverty impacts.

This study examined the impact of organizational characteristics and financial performance measures of faith based organizations (FBOS) in Pennsylvania and Ohio on the decisions of the funding sources. Organizational characteristics of size, age, and type of service, and financial performance measures such as expense, liquidity, and solvency ratios were gathered from the data on IRS form 990 for 97 FBOS for the period of 1995 to 2004. The study found that the 1996 Charitable Choice provisions and the 2001 Office of Faith-Based and Community Initiatives have led to increased government funding for FBOS. The results showed that government funding of FBOS is affected positively by age of the FBO, and negatively by its size. For smaller FBOS, savings ratio had a negative relationship to government funding and a positive relationship to direct public support. For social service FBOS government funding was positively affected by age and negatively affected by size and debt ratio, while days-cash-on-hand had a negative impact on direct public support. All of the above relationships were statistically significant.

Traumatic dental injury (TDI) during childhood may negatively impact the quality of life of children. To describe the association of oral health-related quality of life (OHRQoL) and domains (oral symptons, functional limitation, emotional- and social-well-being) of children with individual and contextual variables. A cross-sectional study was performed using a representative sample of 1,201 schoolchildren, 8-10 years-old, from public and private schools of Belo Horizonte, Brazil. The CPQ8-10 was used to assess OHRQoL, dichotomized in low and high impact. Sociodemographic information was collected through questionnaires to parents. Children were examined at schools, using the Andreasen criteria. Individual variables were gender, age, number of residents in home, parents/caregivers' level of education, family income, and TDI (dichotomized into without trauma/mild trauma and severe trauma). Dental caries and malocclusion were considered co-variables. Contextual variables were the Social Vulnerability Index and type of school. Ethical approval and consent forms were obtained. Data were analyzed using SPSS for Windows 19.0 and HLM 6.06, including frequency distribution, chi-squared test and multilevel approach (p < 0.05). The prevalence of a negative impact on OHRQoL in children with severe trauma was 55.9%. The TDI negatively impacted emotional and social domains of OHRQoL. A multilevel analysis revealed a significant difference in OHRQoL according to the type of school and showed that 16% of the total variance was due to contextual characteristics (p < 0.001; ICC = 0.16). The negative impact on OHRQoL was higher in girls (p = 0.009), younger children (p = 0.023), with severe TDI (p = 0.014), those from public schools (p = 0.017) and whose parents had a lower education level (p = 0.001). Severe trauma impacts OHRQoL on emotional and social domains. Contextual dimensions add information to individual variability to explain higher impact, emphasizing socioeconomic inequalities.

Our study examines the impact of breast cancer-related lymphedema on women's work and career. Our research addresses a significant knowledge gap regarding the additional impact of lymphedema on breast cancer survivors. An online national survey was conducted with 361 women who either had breast cancer without lymphedema (Group 1, n = 209) or breast cancer with lymphedema (Group 2, n = 152). Participant recruitment was supported by the Breast Cancer Network Australia and the Australasian Lymphology Association. Both breast cancer and lymphedema had a significant negative influence on women's work and career. Respondents reported changes in employment resulting from stress and/or physical impairment, which affected attendance and work performance. The perceived negative impact of breast cancer on respondents' work and career was noticeably greater in Group 2 (63 %) than Group 1 (51 %) (p = 0.03). Of the participants who were in paid employment at some time (either at diagnosis of lymphedema or at the time of the survey (n = 103), 43 (42 %) indicated that lymphedema impacted their work performance. The impact of lymphedema on work was incremental with increased severity of lymphedema (range 22-75 %). The annual number of days off work for subclinical/mild lymphedema participants was 1.4 versus 8.1 days for moderate or severe participants (p = 0.003). This study identifies an additional detrimental effect of lymphedema on women's work and career over and above the initial impact of breast cancer and provides empirical evidence for future prospective studies and policy improvement.

The aims of the current study were to examine the indirect effect of the perceived impact of pregnancy on quality of life (QoL) through the severity of depressive symptoms among a sample of pregnant adolescents, and to explore whether adolescents' satisfaction with support from their mothers (SM) or partners (SP) was a buffer of this effect. Demographic and pregnancy-related data were collected for 395 pregnant adolescents age 12-19 and were controlled for testing the proposed indirect effect. SM and SP were tested as moderators of the links between perceived impact of pregnancy and depressive symptoms and between depressive symptoms and QoL. A computational tool for path analysis-based moderation and mediation analysis as well as their combination was used to test indirect and interaction effects (PROCESS). A significant indirect effect of the perceived impact of pregnancy on QoL through the severity of depressive symptoms was found (0.51, CI = 0.29/0.78). There was no significant direct effect of the perceived impact of pregnancy on QoL after controlling for the severity of depressive symptoms. SM and SP buffered the indirect effect by weakening the association between a negative perception of the impact of pregnancy and higher severity of depressive symptoms. Identifying adolescents with a negative perception of the impact of pregnancy, improving the quality of their relations with their mothers and partners, and promoting satisfactory support from these figures may be extremely important to prevent and treat depressive symptoms and, in so doing, improve adolescents' QoL during pregnancy.

Grapevine leafroll disease (GLD) is an economically important virus disease affecting wine grapes (Vitis vinifera L.), but little is known about its effect on wine chemistry and sensory composition of wines. In this study, impacts of GLD on fruit yield, berry quality and wine chemistry and sensory features were investigated in a red wine grape cultivar planted in a commercial vineyard. Own-rooted Merlot vines showing GLD symptoms and tested positive for Grapevine leafroll-associated virus 3 and adjacent non-symptomatic vines that tested negative for the virus were compared during three consecutive seasons. Number and total weight of clusters per vine were significantly less in symptomatic relative to non-symptomatic vines. In contrast to previous studies, a time-course analysis of juice from grapes harvested at different stages of berry development from symptomatic and non-symptomatic vines indicated more prominent negative impacts of GLD on total soluble solids (TSS) and berry skin anthocyanins than in juice pH and titratable acidity. Differences in TSS between grapes of symptomatic and non-symptomatic vines were more pronounced after the onset of véraison, with significantly lower concentrations of TSS in grapes from symptomatic vines throughout berry ripening until harvest. Wines made from grapes of GLD-affected vines had significantly lower alcohol, polymeric pigments, and anthocyanins compared to corresponding wines from grapes of non-symptomatic vines. Sensory descriptive analysis of 2010 wines indicated significant differences in color, aroma and astringency between wines made from grapes harvested from GLD-affected and unaffected vines. The impacts of GLD on yield and fruit and wine quality traits were variable between the seasons, with greater impacts observed during a cooler season, suggesting the influence of host plant × environment interactions on overall impacts of the disease.

Studies have documented a link between distracted driving and diminished safety; however, an association between distracted driving and traffic congestion has not been investigated in depth. The present study examined the behavior of teens and young adults operating a driving simulator while engaged in various distractions (i.e., cell phone, texting, and undistracted) and driving conditions (i.e., free flow, stable flow, and oversaturation). Seventy five participants 16 to 25 years of age (split into 2 groups: novice drivers and young adults) drove a STISIM simulator three times, each time with one of three randomly presented distractions. Each drive was designed to represent daytime scenery on a 4 lane divided roadway and included three equal roadway portions representing Levels of Service (LOS) A, C, and E as defined in the 2000 Highway Capacity Manual. Participants also completed questionnaires documenting demographics and driving history. Both safety and traffic flow related driving outcomes were considered. A Repeated Measures Multivariate Analysis of Variance was employed to analyze continuous outcome variables and a Generalized Estimate Equation (GEE) poisson model was used to analyze count variables. Results revealed that, in general more lane deviations and crashes occurred during texting. Distraction (in most cases, text messaging) had a significantly negative impact on traffic flow, such that participants exhibited greater fluctuation in speed, changed lanes significantly fewer times, and took longer to complete the scenario. In turn, more simulated vehicles passed the participant drivers while they were texting or talking on a cell phone than while undistracted. The results indicate that distracted driving, particularly texting, may lead to reduced safety and traffic flow, thus having a negative impact on traffic operations. No significant differences were detected between age groups, suggesting that all drivers, regardless of age, may drive in a manner that impacts safety and traffic flow negatively when distracted.

This study examines the impact of economic growth, corruption, health, and poverty on environmental degradation for three countries from ASEAN, namely Indonesia, Malaysia, and Thailand using annual data over the period of 1994-2014. The relationship between environmental degradation (pollution) by carbon dioxide (CO 2 ) emissions and economic growth is examined along with some other variables, namely health expenditure, poverty, agriculture value added growth, industrial value added growth, and corruption. The ordinary least squares (OLS) method is applied as an analytical technique for parameter estimation. The empirical results reveal that almost all variables are statistically significant at the 5% level of significance, whereby test rejects the null hypotheses of non-cointegration, indicating that all variables play an important role in affecting the environment across countries. Empirical results also indicate that economic growth has significant positive impact, while health expenditures show significantly negative impact on the environment. Corruption has significant positive effect on environment in the case of Malaysia; while in the case of Indonesia and Thailand, it has insignificant results. However, for the individual analysis across countries, the regression estimate suggests that economic growth has a significant positive relationship with environment for Indonesia, while it is found insignificantly negative and positive in the case of Malaysia and Thailand, respectively, during the period under the study. Empirical findings of the study suggest that policy-makers require to make technological-friendly environment sequentially to surmount unregulated pollution, steady population transfers from rural areas to urban areas are also important, and poverty alleviation and better health provision can also help to improve the environment.

The impact of frozen sections on final surgical margins in squamous cell carcinoma of the oral cavity and lips: a retrospective analysis over an 11 years period

PubMed Central

2011-01-01

Background Taking intraoperative frozen sections (FS) is a widely used procedure in oncologic surgery. However so far no evidence of an association of FS analysis and premalignant changes in the surgical margin exists. Therefore, the aim of this study was to evaluate the impact of FS on different categories of the final margins of squamous cell carcinoma (SCC) of the oral cavity and lips. Methods FS, pT-stage, grading, and tumor localization of 178 patients with SCC of the oral cavity and lips were compared by uni- and multivariate analysis in patients with positive, dysplastic and negative surgical margin status. Results Performed on 111 patients (62.4%), intraoperative FS did not have any statistically significant influence on final margin status, independent of whether it was positive (p = 0.40), dysplastic (p = 0.70), or negative (p = 0.70). Positive surgical margins in permanent sections were significantly associated with pT4-tumors (OR 5.61, p = 0.001). The chance for negative margins in permanent sections was significantly higher in tumors located in the tongue (OR 4.70, p = 0.01). Conclusions Our data suggests that intraoperative FS in SCC can be useful in selected cases. However it is not advisable as a routine approach. PMID:22208692

In 2005, competition was introduced in part of the hospital market in the Netherlands. Using a unique dataset of transactions and list prices between hospitals and insurers in the years 2005 and 2006, we estimate the influence of buyer and seller concentration on the negotiated prices. First, we use a traditional structure-conduct-performance model (SCP-model) along the lines of Melnick et al. (J Health Econ 11(3): 217-233, 1992) to estimate the effects of buyer and seller concentration on price-cost margins. Second, we model the interaction between hospitals and insurers in the context of a generalized bargaining model similar to Brooks et al. (J Health Econ 16: 417-434, 1997). In the SCP-model, we find that the market shares of hospitals (insurers) have a significantly positive (negative) impact on the hospital price-cost margin. In the bargaining model, we find a significant negative effect of insurer concentration, but no significant effect of hospital concentration. In both models, we find a significant impact of idiosyncratic effects on the market outcomes. This is consistent with the fact that the Dutch hospital sector is not yet in a long-run equilibrium.

The aim of the current study was to investigate the psychosocial impact of dental aesthetics among patients who received anterior implant-supported prostheses. The current study is a cross-sectional evaluation involving 115 individuals who had gone through treatment at the dental clinics of general hospitals. Participants completed the Chinese version of the psychosocial impact of dental aesthetics questionnaire (PIDAQ) before implantation and six months after crown restoration. Basic demographic information was recorded. Six months after implant crown restoration, participants were asked to self-assess their own oral aesthetics compared to before implantation. A total of 106 patients completed the study. PIDAQ scores correlated significantly with the self-assessment of the degree of oral aesthetics. Six months after crown restoration, the two factors (social impact and aesthetic attitude) decreased and the dental self-confidence score increased significantly compared to pre-implantation scores. Gender and education level significantly affected PIDAQ. Anterior implant-supported prostheses significantly affected the patients' psychosocial perception. Implantation of missing anterior teeth can significantly improve patients' negative psychosocial impact of dental aesthetics. Gender and education level are correlated with the degree of improvement. The PIDAQ can be used in assessing the psychosocial effects of implantation in missing anterior teeth.

There is research suggesting that binge eating may serve an affect regulation function. However, experimental evidence supporting this model in adults is sparse and studies have been mixed regarding whether negative affect impacts objective energy intake. This study examined the impact of a real-time interpersonal stressor on laboratory test meal intake between individuals endorsing recent objective binge eating (≥1x/week) and those denying disordered eating. Generalized linear modeling was used to compare individuals with recent binge eating (BE group; n = 52) to those denying recent eating pathology (HC group; n = 51) on test meal intake following a stressor (stressful condition) or neutral stimulus (non-stressful condition). Moderated mediation analyses were used to examine whether negative affect mediated the impact of condition on intake differently between BE and HC groups. The BE group did not have significantly higher energy intake than the HC group in the stressful verses non-stressful condition. However, the BE group was more likely to engage in extreme intake (i.e., over- or under-consumption) than the HC group in the stressful versus non-stressful condition (p = .02). Changes in negative affect did not significantly mediate the relationship between condition and intake extremes for the BE group. The results indicate that both over- and under-consumption are triggered by stress among individuals with recent binge eating. Continued research investigating both binge eating and restriction as a means of affect regulation in binge-eating samples is encouraged. PMID:27940313

A negative birth experience has been shown to have a significant impact on the well-being and future choices of mothers. The objective of this study was to assess the prevalence of, and identify the risk factors associated with a negative birth experience for women in Canada. The study was based on secondary data analysis of the Maternity Experiences Survey (MES), a Canadian population database administered to 6,421 Canadian women in 2006. The examined outcome - negative birth experience - was derived from mothers' self-report of overall labour and birth experience. Independent variables were maternal demographics, health characteristics, pregnancy-related characteristics, and birth characteristics. Multivariable logistic regression analysis was performed to determine the significant predictors of negative birth experience. Adjusted Odds Ratios (AOR) and 95 % Confidence Intervals (CI) are reported. Negative birth experience was reported among 9.3 % of women. The main significant predictors of a negative birth experience included older age (AOR 2.29, 95 % CI, 1.03-5.07), violence experienced in the past two years (AOR, 1.62, 95 % CI, 1.21-2.18), poor self-perceived health (adjusted OR, 1.95, 95 % CI, 1.36-2.80), prenatal classes attended (adjusted OR, 1.36, 95 % CI, 1.06-1.76), unintended pregnancy (adjusted OR, 1.30, 95 % CI, 1.03-1.63), caesarean birth (AOR, 1.65, 95 % CI, 1.32-2.06), and neonate admission to intensive care (AOR, 1.40, 95 % CI, 1.08-1.82). Significant predictors of a negative labour and birth experience were identified through this study, a first in the Canadian context. These findings suggest future research directions and provide a basis for the design and evaluation of maternal health policy and prevention programs.

Human papillomavirus (HPV) test was incorporated into the triage of lesser abnormal cervical cytologies: atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesion (LSIL). This study aimed to evaluate the impact of age on the efficacy of HPV testing in patients with lesser abnormal cervical cytologies. A total of 439 patients with ASCUS or LSIL were included. The association between age groups and the diagnostic performances of HPV test for high-grade cervical intraepithelial neoplasia (CIN2+) was evaluated. Median age was 44 years (range, 17 to 75 years). ASCUS was more frequently observed in older patients while LSIL was more common in younger patients (P=0.002). CIN2+ was found in 11.3% (32/284) of the ASCUS patients and 12.9% (20/155) of patients with LSIL. Older patients with ASCUS showed lower HPV infection rates (P=0.025), but not LSIL (P=0.114). However, the prevalence of CIN2+ was similar between the age groups with ASCUS or LSIL. In patients with ASCUS, the false negative rate of HPV test for CIN2+ was 6.2%. The false negative rate of the HPV test became higher with increasing of the age after the age of 50 (P=0.034). Our findings suggest that false negative rate of the HPV test for CIN2+ in ASCUS patients older than 50 years might become higher with increasing of the age. Negative HPV results in patients of the age >50 years with ASCUS should be carefully interpreted.

Complex abdominal wall reconstruction is beset by postoperative complications. A recent meta-analysis comparing the use of closed-incision negative-pressure therapy to standard dressings found a statistically significant reduction in surgical-site infection. The use of closed-incision negative-pressure therapy is gaining acceptance in this population; however, the economic impact of this innovative dressing remains unknown. In this study, a cost-utility analysis was performed assessing closed-incision negative-pressure therapy and standard dressings following closure of abdominal incisions in high-risk patients. Cost-utility methodology involved reviewing literature related to closed-incision negative-pressure therapy in abdominal wall surgery, obtaining utility estimates to calculate quality-adjusted life-year scores for successful surgery and surgery complicated by surgical-site infection, summing costs using Medicare Current Procedural Terminology codes, and creating a decision tree illuminating the most cost-effective dressing strategy. One-way sensitivity analysis was performed to assess the robustness of the results. The aforementioned meta-analysis comparing closed-incision negative-pressure therapy to standard dressings included a subset of five studies assessing abdominal wall surgery in 829 patients (260 closed-incision negative-pressure therapy and 569 standard dressings). Decision tree analysis revealed an estimated savings of $1546.52 and a gain of 0.0024 quality-adjusted life-year with closed-incision negative-pressure therapy compared with standard dressings; therefore, closed-incision negative-pressure therapy is a dominant treatment strategy. One-way sensitivity analysis revealed that closed-incision negative-pressure therapy is a cost-effective option when the surgical-site infection rate is greater than 16.39 percent. The use of closed-incision negative-pressure therapy is cost-saving following closure of abdominal incisions in high-risk patients.

This study investigates how personality traits in combination with frequency of and emotional reaction to negative comments about appearance while growing up are related to appearance evaluation and orientation among adult women. Nine hundred and seven participants from a representative sample of Norwegian women aged 22-55, answered questions measuring body image, personality (Big Five), and history of experiencing negative comments about appearance. Results indicated that only emotional reaction to negative comments about appearance significantly predicted both appearance evaluation and orientation, while frequency of negative comments did not. Being extrovert predicted more positive appearance evaluation and being more appearance oriented than being introvert. Scoring high on neuroticism was related to negative appearance evaluation and high appearance orientation. The findings demonstrate the importance of differentiating between the frequency and the emotional impact of teasing as well as including personality traits when studying body image.

Characterization and Identification of Productivity-Associated Rhizobacteria in Wheat

Habiger, Joshua

2012-01-01

The rhizosphere is populated by a numerous and diverse array of rhizobacteria, and many impact productivity in largely unknown ways. Here we characterize the rhizobacterial community in a wheat variety categorized according to shoot biomass using 16S rRNA pyrosequencing abundance data. Plants were grown in homogenized field soil under greenhouse conditions, and DNA was extracted and pyrosequenced, resulting in 29,007 quality sequences. Operational taxonomic units (OTUs) that were significantly associated with biomass productivity were identified using an exact test adjusted for the false-discovery rate. The productivity deviation expressed as a percentage of the total mean square for regression (PMSR) was determined for each OTU. Out of 719 OTUs, 42 showed significant positive associations and 39 showed significant negative associations (q value, ≤0.05). OTUs with the greatest net positive associations, by genus, were as follows: Duganella, OTU 43 and OTU 3; Janthinobacterium, OTU 278; Pseudomonas, OTU 588; and Cellvibrio, OTU 1847. Those with negative associations were as follows: Bacteria, OTU 273; Chryseobacterium, OTU 508; Proteobacteria, OTU 249; and Enterobacter, OTU 357. Shoot biomass productivity was strongly correlated with the balance between the overall abundances of positive- and negative-productivity-associated OTUs. High-productivity rhizospheres contained 9.2 significant positives for every negatively associated rhizobacterium, while low-productivity rhizospheres showed 2.3 significant negatives for every positively associated rhizobacterium. Overall rhizobacterial community diversity as measured by the Chao1, Shannon, and Simpson indexes was nonlinearly related to productivity, closely fitting a wavelike cubic equation. We conclude that shoot biomass productivity is strongly related to the ratio of positive- to negative-productivity-associated rhizobacteria in the rhizosphere. This study identifies significant OTUs composing the productive and unproductive rhizobacterial communities. PMID:22504815

To evaluate how soft lens power affects rigid gas-permeable (RGP) lens power and visual acuity (VA) in piggyback fittings for keratoconus. Sixteen keratoconus subjects (30 eyes) were included in the study. Piggyback contact lens fittings combining Senofilcon-A soft lenses of -6.00, -3.00, +3.00 and +6.00 D with Rose K2 RGP contact lenses were performed. Corneal topography was taken on the naked eye and over each soft contact lens before fitting RGP lenses. Mean central keratometry, over-refraction, RGP back optic zone radius (BOZR) and estimated final power as well as VA were recorded and analyzed. In comparison to the naked eye, the mean central keratometry flattened with both negative lens powers (p<0.05 in all cases), did not change with the +3.00 soft lens power (p=1.0); and steepened with the +6.00 soft lens power (p=0.02). Rigid gas-permeable over-refraction did not change significantly between different soft lens powers (all p>0.05). RGP's BOZR decreased significantly with both positive in comparison with both negative soft lens powers (all p<0.001), but no significant differences were found among negative- or positive-powers separately (both p>0.05). Estimated RGP's final power increased significantly with positive in comparison with negative lens powers (all p<0.001), but no significant differences were found among negative or positive lens powers separately (both p>0.05). Visual acuity did not change significantly between the different soft lens powers assessed (all p>0.05). The use of negative-powered soft lenses in piggyback fitting reduces RGP lens power without impacting VA in keratoconus subjects. Copyright © 2014 British Contact Lens Association.

This study quantified climatological and hydrological trends and relationships to presence and distribution of two native aquatic species in the Kansas River Basin over the past half-century. Trend analyses were applied to indicators of hydrologic alteration (IHAs) at 34 streamgages over a 50-year period (1962-2012). Results showed a significant negative trend in annual streamflow for 10 of 12 western streamgages (up to -7.65 mm/50 yr) and smaller negative trends for most other streamgages. Significant negative trends in western Basin streamflow were more widespread in summer (12 stations) than winter or spring (6 stations). The negative-trend magnitude and significance decreased from west to east for maximum-flow IHAs. Minimum- flow IHAs, however, significantly decreased at High Plains streamgages but significantly increased at Central Great Plains streamgages. Number of zero-flow days showed positive trends in the High Plains. Most streamgages showed negative trends in low- and high-flow pulse frequency and high-flow pulse duration, and positive trends in low-flow pulse duration. These results were consistent with increasing occurrence of drought. Shift in occurrence from present (1860-1950) to absent (2000-2012) was significantly related (p<0.10) to negative trends of 1-day maximum flows (both species) and indices associated with reduced spawning-season flows for Plains Minnow and shifting annual-flow timing and increased flow intermittency for Common Shiner. Both species were absent for all western Basin sites and had different responses to hydrological index trends at eastern Basin sites. These results demonstrate ecohydrological index changes impact distributions of native fish and suggest target factors for assessment or restoration activities.

Previous studies showed that negative self-stereotypes detrimentally affect the cognitive performance of marginalized group members; however, these findings were confined to short-term experiments. In the present study, we considered whether stereotypes predicted memory over time, which had not been previously examined. We also considered whether self-relevance increased the influence of stereotypes on memory over time. Multiple waves of memory performance were analyzed using individual growth models. The sample consisted of 395 participants in the Baltimore Longitudinal Study of Aging. Those with more negative age stereotypes demonstrated significantly worse memory performance over 38 years than those with less negative age stereotypes, after adjusting for relevant covariates. The decline in memory performance for those aged 60 and above was 30.2% greater for the more negative age stereotype group than for the less negative age stereotype group. Also, the impact of age stereotypes on memory was significantly greater among those for whom the age stereotypes were self-relevant. This study shows that the adverse influence of negative self-stereotypes on cognitive performance is not limited to a short-term laboratory effect. Rather, the findings demonstrate, for the first time, that stereotypes also predict memory performance over an extended period in the community.

Research Topic: The aim of this study was to determine the relative contribution of trait negative affect and individual psychological resilience in explaining the professional quality of life of nurses. Materials and Methods: One thousand, seven hundred and forty-three Australian nurses from the public, private, and aged care sectors completed an online Qualtrics survey. The survey collected demographic data as well as measures of depression, anxiety and stress, trait negative affect, resilience, and professional quality of life. Results: Significant positive relationships were observed between anxiety, depression and stress, trait negative affectivity, burnout, and secondary traumatic stress (compassion fatigue). Significant negative relationships were observed between each of the aforementioned variables and resilience and compassion satisfaction (CS). Results of mediated regression analysis indicated that resilience partially mediates the relationship between trait negative affect and CS. Conclusion: Results confirm the importance of both trait negative affect and resilience in explaining positive aspects of professional quality of life. Importantly, resilience was confirmed as a key variable impacting levels of CS and thus a potentially important variable to target in interventions aimed at improving nurse’s professional quality of life.

Bothriocephalus acheilognathi Yamaguti, 1934, a tapeworm known to be pathogenic to some fish species, has become established in the endangered humpback chub (Gila cypha Miller, 1964) in Grand Canyon, USA, following the tapeworm’s introduction into the Colorado River system. The potential impact of this tapeworm on humpback chub was studied by exposing the closely related bonytail chub (Gila elegans Baird and Girard, 1853) to the parasite under a range of conditions that included potential stressors of humpback chub in their natal waters, such as abrupt temperature change and a limited food base. Survival of infected fish under low food rations was considerably lower than that of control fish, and mortality of infected fish began 20 days earlier. Growth of infected fish was significantly reduced, and negative changes in health condition indices were found. No significant negative impacts were revealed from the synergistic effects between temperature shock and infection. Bothriocephalus acheilognathi does present a potential threat to humpback chub in Grand Canyon and should be considered, along with conventional concerns involving altered flow regimes and predation, when management decisions are made concerning conservation of this endangered species.

We used panel data from the Indonesian Family Life Survey to investigate the impact of health insurance programs on reducing out-of-pocket expenditures. We employed three linear panel data models, two of which accounted for endogeneity: pooled ordinary least squares (OLS), pooled two-stage least squares (2SLS) for instrumental variable (IV), and fixed effects (FE). The study revealed that two health insurance programs had a significantly negative impact on out-of-pocket expenditures by using IV estimates. In the IV model, Askeskin decreased out-of-pocket expenditures by 34% and Askes by 55% compared with non-Askeskin and non-Askes, respectively, while Jamsostek was found to bear a nonsignificant effect on out-of-pocket expenditures. In the FE model, only Askeskin had a significant negative effect with an 11% reduction on out-of-pocket expenditures. This study showed that two large existing health insurance programs in Indonesia, Askeskin and Askes, effectively reduced household out-of-pocket expenditures. The ability of programs to offer financial protection by reducing out-of-pocket expenditures is likely to be a direct function of their benefits package and co-payment policies.

Negative Gaussian curvature induces significant suppression of thermal conduction in carbon crystals.

Zhang, Zhongwei; Chen, Jie; Li, Baowen

2017-09-28

From the mathematic category of surface Gaussian curvature, carbon allotropes can be classified into three types: zero curvature, positive curvature, and negative curvature. By performing Green-Kubo equilibrium molecular dynamics simulations, we found that surface curvature has a significant impact on the phonon vibration and thermal conductivity (κ) of carbon crystals. When curving from zero curvature to negative or positive curvature structures, κ is reduced by several orders of magnitude. Interestingly, we found that κ of negatively curved carbon crystals exhibits a monotonic dependence on curvature. Through phonon mode analysis, we show that curvature induces remarkable phonon softening in phonon dispersion, which results in the reduction of phonon group velocity and flattening of phonon band structure. Furthermore, the curvature was found to induce phonon mode hybridization, leading to the suppression of phonon relaxation time. Our study provides physical insight into thermal transport in curvature materials, and will be valuable in the modulation of phonon activity through surface curvature.

The Stereotype-Matching Effect: Greater Influence on Functioning When Age Stereotypes Correspond to Outcomes

2009-01-01

Older individuals assimilate, and are targeted by, contradictory positive and negative age stereotypes. It was unknown whether the influence of stereotype valence is stronger when the stereotype content corresponds to the outcome domain. We randomly assigned older individuals to either positive-cognitive, negative-cognitive, positive-physical, or negative-physical subliminal-age-stereotype groups and assessed cognitive and physical outcomes. As predicted, when the age stereotypes corresponded to the outcome domains, their valence had a significantly greater impact on cognitive and physical performance. This suggests that if a match occurs, it is more likely to generate expectations that become self-fulfilling prophecies. PMID:19290757

The purpose of this study was to explore the continuing impact of growing up with an ill sibling on well siblings' late adolescent functioning. Forty late adolescents (M age = 18.78, SD = 0.83), who identified themselves as growing up with an ill sibling, completed a semistructured interview, demographic questionnaire, Personality Assessment Screener, and My Feelings and Concerns Sibling Questionnaire. Participants reported clinically significant problems on some PAS scales, and gender differences were found for acting out and alienation. Significant relationships were reported for communication and social withdrawal and alienation. Both positive and negative themes about the experience were elicited from the responses in the semistructured interview. This study provides evidence for some lingering negative effects of growing up with an ill sibling on well siblings' late adolescent functioning. Additionally, evidence for siblings' development of positive characteristics that may act as protective variables as they face the stressors of late adolescence was also highlighted. PMID:24959574

The impact of conflict on co-parenting outcomes of divorce education programs is not widely explored in the literature despite the prevalence of conflict in divorce. This study used outcome data from a sample of participants (N=272) who took the online Parents Forever™ course between 2012 and 2014. Participants were asked questions about positive and negative co-parenting behaviors as well their levels of conflict before and after the divorce or separation. There was on average a slight increase in conflict from post to follow-up (M=-0.397, SD=1.54). Simple linear regression analyses indicated that change in conflict explained a significant proportion of the variance in positive co-parenting scores, R 2 =0.07, F(1, 270)=19.98, p<0.001 and negative co-parenting scores, R 2 =0.08, F(1, 270)=23.78, p<0.001. Results suggest that conflict significantly impacts co-parenting behaviors targeted in the Parents Forever ™ course. Copyright © 2017 Elsevier Ltd. All rights reserved.

Goal orientation and self-efficacy in relation to memory in adulthood

Hastings, Erin C.; West, Robin L.

2011-01-01

The achievement goal framework (Dweck, 1986) has been well-established in children and college-students, but has rarely been examined empirically with older adults. The current study, including younger and older adults, examined the effects of memory self-efficacy, learning goals (focusing on skill mastery over time) and performance goals (focusing on performance outcome evaluations) on memory performance. Questionnaires measured memory self-efficacy and general orientation toward learning and performance goals; free and cued recall was assessed in a subsequent telephone interview. As expected, age was negatively related and education was positively related to memory self-efficacy, and memory self-efficacy was positively related to memory, in a structural equation model. Age was also negatively related to memory performance. Results supported the positive impact of learning goals and the negative impact of performance goals on memory self-efficacy. There was no significant direct effect of learning or performance goals on memory performance; their impact occurred via their effect on memory self-efficacy. The present study supports past research suggesting that learning goals are beneficial, and performance goals are maladaptive, for self-efficacy and learning, and validates the achievement goal framework in a sample including older adults.

Surgical correction of congenital cardiac malformations mostly implies the use of cardiopulmonary bypass (CPB). However, a possible negative impact of CPB on cerebral structures like the hippocampus cannot be neglected. Therefore, we investigated the effect of CPB on hippocampus CA1 and CA3 regions without or with the addition of epigallocatechin-3-gallate (EGCG) or minocycline. We studied 42 piglets and divided them into six experimental groups: control without or with EGCG or minocycline, CPB without or with EGCG or minocycline. The piglets underwent 90 minutes CPB and subsequently, a 120-minute recovery and reperfusion phase. Thereafter, histology of the hippocampus was performed and the adenosine triphosphate (ATP) content was measured. Histologic evaluation revealed that CPB produced a significant peri-cellular edema in both CA regions. Moreover, we found an increased number of cells stained with markers for hypoxia, apoptosis and nitrosative stress. Most of these alterations were significantly reduced to or near to control levels by application of EGCG or minocycline. ATP content was significantly reduced within the hippocampus after CPB. This reduction could not be antagonized by EGCG or minocycline. In conclusion, CPB had a significant negative impact on the integrity of hippocampal neural cells. This cellular damage could be significantly attenuated by addition of EGCG or minocycline. © 2015 International Society of Neuropathology.

Espejo, Emmanuel P.; Hammen, Constance; Brennan, Patricia A.

2012-01-01

The tendency to appraise naturally occurring life events (LEs) as having high negative impact may be a predisposing factor for the development of depression and anxiety disorders. In the current study, appraisals of the negative impact of recent LEs were examined in relationship to depressive and anxiety disorders in a sample of 653 adolescents who were administered diagnostic and life stress interviews at ages 15 and 20. Participants’ appraisals of the negative impact of LEs reported at age 15 were statistically adjusted using investigator-based ratings to control for objective differences across LEs. Higher appraisals of the negative impact of LEs were associated with both past and current depressive and anxiety disorders at age 15 and predicted subsequent first onsets of depressive and anxiety disorders occurring between ages 15 and 20. In addition, appraisals of the negative impact of LEs were particularly elevated among those experiencing both a depressive and anxiety disorder over the course of the study. The findings suggest that systematically elevated appraisals of the negative impact of LEs is a predisposing factor for depression and anxiety disorders and may represent a specific risk factor for co-morbid depression and anxiety in mid-adolescence and early adulthood.

What Influences Recommendations Issued by the Agency for Health Technology Assessment in Poland? A Glimpse Into Decision Makers' Preferences.

PubMed

Niewada, Maciej; Polkowska, Małgorzata; Jakubczyk, Michał; Golicki, Dominik

This study aimed to evaluate the factors that are associated with positive (supporting public funding) and negative recommendations of the Agency for Health Technology Assessment in Poland. Two independent analysts reviewed all the recommendations publicly available online before October 7, 2011. For each recommendation, predefined decision rationales, that is, clinical efficacy, safety, cost-effectiveness, and formal aspects, were sought, either advocating or discouraging the public financing. In the analysis, we used descriptive statistics and a logistic regression model so as to identify the association between predefined criteria and the recommendation being positive. We identified 344 recommendations-218 positive (62.8%) and 126 negative (37.2%). Negative recommendations were better justified and also the comments were less ambiguous in accordance with the recommendation (except for clinical efficacy). In general, the specified criteria supported the decision (either positive or negative) in 209 (60.8%), 107 (31.1%), 124 (36.0%), 96 (27.9%), and 61 (17.7%) recommendations, respectively, and ran contrary to the actual decision in the remaining ones. Threshold values for either cost-effectiveness or budget impact distinguishing positive from negative recommendations could not be specified. The following parameters reached statistical significance in logistic regression: clinical efficacy (both explicitly positive and explicitly negative evaluations impacted in opposite directions), lack of impact on hard end points, unfavorable safety profile, cost-effectiveness results, and formal shortcomings (all reduced the probability of a positive recommendation). Decision making of the Agency for Health Technology Assessment in Poland is multicriterial, and its results cannot be easily decomposed into simple associations or easily predicted. Still, efficacy and safety seem to contribute most to final recommendations. Copyright © 2013, International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Published by Elsevier Inc.

Child oral health-related quality of life (COHRQoL) has been assessed in developed areas; however, it remains unstudied in mainland China. Studies on COHRQoL would benefit a large number of children in China suffering from oral health problems such as dental caries. This study explored the relationship between COHRQoL and early childhood caries, adjusted by socioeconomic factors, in 3- to 4-year-old children in a region of southern China. In this study, 1062 children aged 3-4 years were recruited by cluster sampling and their oral health statuses were examined by a trained dentist. The Chinese version of the Early Childhood Oral Health Impact Scale (ECOHIS) and questions about the children's socioeconomic conditions were completed by the children's parents. A negative binomial regression analysis was used to assess the prevalence of early childhood caries among the children and its influence on COHRQoL. The total ECOHIS scores of the returned scale sets ranged from 0 to 31, and their average scores was 3.1±5.1. The negative binomial analysis showed that the dmfs indices were significantly associated with the ECOHIS score and subscale scores (P<0.05). The multivariate adjusted model showed that a higher dmft index was associated with greater negative impact on COHRQoL (RR = 1.10; 95% CI = 1.07, 1.13; P < 0.05). However, demographic and socioeconomic factors were not associated with COHRQoL (P>0.05). The severity of early childhood caries has a negative impact on the oral health-related quality of life of preschool children and their parents.

This study examined the effects of virtual contact with nature on positive and negative affect, and investigated the psychological process of perceived restorativeness as a mediator of this relationship. A sample of 220 Australians aged between 18 and 75 years (M = 49.07, SD = 14.34, female = 72%) participated in the study. Participants were randomly allocated to one of the three experimental conditions experienced through video presentations: (1) ‘wild’ nature, (2) ‘urban’ nature, and (3) non-nature control. They then completed measures of perceived restorativeness as well as positive and negative affect. Compared to the non-nature control condition, the experience of wild nature resulted in significantly higher levels of positive affect and lower levels of negative affect. The experience of urban nature resulted in significantly lower levels of negative affect only compared to the non-nature control video. Experience of wild and urban nature resulted in greater perceptions of restorativeness as compared to the non-nature control video. Restorativeness was a significant underlying psychological mediating path through which nature experience exerted its influence on affect. These results have the potential to inform nature-based green care interventions for mental health as well as for urban planning to maximize beneficial effects of natural environments. PMID:28708074

Social-cognitive deficits have a significant impact on the community and vocational functioning of persons with schizophrenia. This study aimed to explore the relationship between social-cognitive abilities and vocational functioning in a Chinese population. We recruited 30 outpatients with schizophrenia to participate. We administered the Chinese Social Cognition and Screening Questionnaire (C-SCSQ) to assess Theory of Mind (ToM), attributional bias, and neurocognition; the Facial Expression Identification Test (FEIT) to assess emotion perception (EP) ability, and the Chinese Work Personality Profile (CWPP) to assess work performance in a simulated work setting. ToM showed a significant negative correlation with attributional bias. The neurocognitive measure displayed a significant positive correlation with ToM and EP. The structural equation model was a good fit to the data (CFI=0.91, RMSEA=0.12), and showed that social-cognitive abilities had a significant impact (-0.41) on work performance. Of the four social-cognitive domains, ToM and paranoid attributional style (PAS) contributed significantly to variations in work performance. These results support the theory that social-cognitive abilities have an impact on work performance. ToM has a positive impact whereas PAS has an adverse effect. Persons with schizophrenia present specific deficits in their social-cognitive abilities, which have significant impact on their work performance and employability.

The occurrence of depression in younger adults is related to the combination of long-standing factors such as personality traits (neuroticism) and more acute factors such as the subjective impact of stressful life events. Whether an increase in physical illnesses changes these associations in old age depression remains a matter of debate. We compared 79 outpatients with major depression and 102 never-depressed controls; subjects included both young (mean age: 35 years) and older (mean age: 70 years) adults. Assessments included the Social Readjustment Rating Scale, NEO Personality Inventory and Cumulative Illness Rating Scale. Logistic regression models analyzed the association between depression and subjective impact of stressful life events while controlling for neuroticism and physical illness. Patients and controls experienced the same number of stressful life events in the past 12 months. However, in contrast to the controls, patients associated the events with a subjective negative emotional impact. Negative stress impact and levels of neuroticism, but not physical illness, significantly predicted depression in young age. In old age, negative stress impact was weakly associated with depression. In this age group, depressive illness was also determined by physical illness burden and neuroticism. Our data suggest that the subjective impact of life stressors, although rated as of the same magnitude, plays a less important role in accounting for depression in older age compared to young age. They also indicate an increasing weight of physical illness burden in the prediction of depression occurrence in old age. © 2013 The Authors.

Background Studies on the relative impact of body mass index in women in childbearing age and gestational weight gain on neonatal outcomes are scarce in the Middle East. Objectives The primary objective of this research was to assess the impact of maternal body mass index (BMI) and gestational weight gain (GWG) on neonatal outcomes. The effect of maternal age and folic acid supplementation before and during pregnancy was also examined. Subjects and methods This is a retrospective cross sectional observational study of 1000 full term deliveries of women enrolled thru the National Collaborative Perinatal Neonatal Network, in Lebanon. Maternal characteristics such as age, BMI and GWG and neonatal outcomes such as weight, height, head circumference and Apgar score were the primary studied variables in this study. Total maternal weight gain were compared to the guidelines depicted by the Institute of Medicine (IOM). Results The negative outcomes of newborns such as lean body weight and macrosomia were significantly present in women who gained respectively below or above the IOM’s cut-off points. Pregestational body mass index influenced significantly the infants’ birth weight, in both the underweight and obese categories. Birth height, head circumference and Apgar score were not influenced by pregestational body mass index or gestational weight gain. No significant associations were found between maternal age and pregestational body mass index and gestational weight gain. Conclusion Studies evaluating the impact of weight before and during pregnancy on neonatal outcomes and anthropometrics measurements are lacking in the Middle East. Our results highlight the importance of nutritional counseling in order to shed the extra weights before conceiving and monitor weight gain to avoid the negative impact on feto-maternal health.

Career scholars have called for a broader definition of career success by inviting greater exploration of its antecedents. While success in various jobs has been predicted by intelligence and in other studies by competencies, especially in management, long term impact of having intelligence and using competencies has not been examined. Even in collegiate outcome studies, few have examined the longer term impact on graduates' careers or lives. This study assesses the impact of demonstrated emotional, social, and cognitive intelligence competencies assessed at graduation and g measured through GMAT at entry from an MBA program on career and life satisfaction, and career success assessed 5 to 19 years after graduation. Using behavioral measures of competencies (i.e., as assessed by others), we found that emotional intelligence competencies predict career satisfaction and success. Adaptability had a positive impact, but influence had the opposite effect on these career measures and life satisfaction. Life satisfaction was negatively affected by achievement orientation and positively affected by teamwork. Current salary, length of marriage, and being younger at time of graduation positively affect all three measures of life and career satisfaction and career success. GMAT (as a measure of g) predicted life satisfaction and career success to a slight but significant degree in the final model analyzed. Meanwhile, being female and number of children positively affected life satisfaction but cognitive intelligence competencies negatively affected it, and in particular demonstrated systems thinking was negative.

To test the hypothesis that malocclusion and its impact on quality of life has no effect on 8- to 10-year-old Brazilian schoolchildren as measured by an oral health-related quality of life (OHRQoL) instrument. A cross-sectional study was carried out with a population-based sample of 1204 8- to 10-year-old children attending elementary schools in Belo Horizonte, Brazil. Dental examinations were carried out by two calibrated examiners. OHRQoL was assessed using the Brazilian version of the Child Perceptions Questionnaire. The Dental Aesthetic Index was used for the clinical assessment of malocclusion. Dental caries and socioeconomic factors were used as controlling variables. Bivariate analysis involved the chi-square test and the Fisher exact test. A Poisson regression model was employed for the multivariate analysis (P < .05). Anterior segment spacing and anterior mandibular overjet were significantly associated with impact on OHRQoL (P < .05). Schoolchildren with malocclusion were 1.30-fold (95% CI: 1.15-1.46; P < 0.001) more likely to experience a negative impact on OHRQoL than those without malocclusion. Children belonging to families with an income less than or equal to two times the minimum wage were 1.59-fold (95% CI: 1.35-1.88; P < 0.001) more likely to experience a negative impact on OHRQoL than those belonging to families with the highest income. Schoolchildren with malocclusion from lower-income families experience a greater negative impact on OHRQoL.

The impact of depression on social economic decision making.

Although the role of emotion in social economic decision making has been increasingly recognized, the impact of mood disorders, such as depression, on such decisions has been surprisingly neglected. To address this gap, 15 depressed and 23 nondepressed individuals completed a well-known economic task, in which they had to accept or reject monetary offers from other players. Although depressed individuals reported a more negative emotional reaction to unfair offers, they accepted significantly more of these offers than did controls. A positive relationship was observed in the depressed group, but not in controls, between acceptance rates of unfair offers and resting cardiac vagal control, a physiological index of emotion regulation capacity. The discrepancy between depressed individuals' increased emotional reactions to unfair offers and their decisions to accept more of these offers contrasts with recent findings that negative mood in nondepressed individuals can lead to lower acceptance rates. This suggests distinct biasing processes in depression, which may be related to higher reliance on regulating negative emotion.

Patients', doctors', and pharmacists' attitudes toward direct-to-consumer advertising (DTCA) for medication and their perceptions of its impact on patient self-reported behavior in terms of request for, and consumption of, advertised medication were investigated. Data were obtained in New Zealand, 1 of only 2 countries that allow mass-media DTCA for prescription medication, and in Belgium, which does not. Attitudes were relatively negative in both countries, but significantly more positive in New Zealand than in Belgium. The impact of DTCA (both in a positive and a negative sense) on self-reported patient behavior and patient interaction with doctors and pharmacists was limited in both countries. Although -- as already established in previous work -- the informativeness and reliability of DTCA can be much improved, and the attitude of medical professionals toward DTCA is negative in both countries, from the point of view of medical professionals and patients, DTCA does not harm the self-reported relationship between doctors, pharmacists, and patients.

Military spouses often have concerns regarding the impact of their communication on soldiers during deployment. However, literature is mixed regarding how communication between soldiers and spouses may impact soldiers’ self-reported work functioning during deployment, suggesting the need to evaluate moderating factors. In the current study, three relationship factors (marital satisfaction, conflictual communication, and proportion of conversation focused on problems) were tested as moderators of communication frequency and negative marriage-to-work spillover for soldiers. Whereas the three relationship factors were independently related to negative spillover, none significantly moderated the relationship between communication frequency and spillover. The overall pattern of results suggests that (a) lower marital satisfaction, a focus on problems during communication, and conflictual communication are each strongly linked to spillover for deployed soldiers, and (b) military couples may be self-restricting deployment communication frequency when experiencing less marital satisfaction and higher rates of negative communication. Implications for communication during deployment are discussed. PMID:26236093

For Video Games, Bad News Is Good News: News Reporting of Violent Video Game Studies.

Copenhaver, Allen; Mitrofan, Oana; Ferguson, Christopher J

2017-12-01

News coverage of video game violence studies has been critiqued for focusing mainly on studies supporting negative effects and failing to report studies that did not find evidence for such effects. These concerns were tested in a sample of 68 published studies using child and adolescent samples. Contrary to our hypotheses, study effect size was not a predictor of either newspaper coverage or publication in journals with a high-impact factor. However, a relationship between poorer study quality and newspaper coverage approached significance. High-impact journals were not found to publish studies with higher quality. Poorer quality studies, which tended to highlight negative findings, also received more citations in scholarly sources. Our findings suggest that negative effects of violent video games exposure in children and adolescents, rather than large effect size or high methodological quality, increase the likelihood of a study being cited in other academic publications and subsequently receiving news media coverage.

Background Chronic pancreatitis (CP) has a profound independent effect on quality of life (QOL). Our aim was to identify factors that impact the QOL in CP patients. Methods We used data on 1,024 CP patients enrolled in the three NAPS2 studies. Information on demographics, risk factors, co-morbidities, disease phenotype and treatments was obtained from responses to structured questionnaires. Physical (PCS) and mental (MCS) component summary scores generated using responses to the Short Form-12 (SF-12) survey were used to assess QOL at enrollment. Multivariable linear regression models determined independent predictors of QOL. Results Mean PCS and MCS scores were 36.7±11.7 and 42.4±12.2, respectively. Significant (p<0.05) negative impact on PCS scores in multivariable analyses was noted due to constant mild-moderate pain with episodes of severe pain or constant severe pain (10 points), constant mild-moderate pain (5.2), pain-related disability/unemployment (5.1), current smoking (2.9 points) and medical co-morbidities. Significant (p<0.05) negative impact on MCS scores was related to constant pain irrespective of severity (6.8-6.9 points), current smoking (3.9 points) and pain-related disability/unemployment (2.4 points). In women, disability/unemployment resulted in an additional reduction 3.7 point reduction in MCS score. Final multivariable models explained 27% and 18% of the variance in PCS and MCS scores, respectively. Etiology, disease duration, pancreatic morphology, diabetes, exocrine insufficiency and prior endotherapy/pancreatic surgery had no significant independent effect on QOL. Conclusion Constant pain, pain-related disability/unemployment, current smoking, and concurrent co-morbidities significantly affect the QOL in CP. Further research is needed to identify factors impacting QOL not explained by our analyses. PMID:28244497

HIV symptoms are associated with a poorer quality of life (QOL) among persons living with HIV/AIDS (PLWHA). Yet, there is little understanding of emotional factors that impact the relation between HIV symptom severity and QOL. The present study examined the main and interactive effects of emotion dysregulation and HIV symptom severity on multiple indices of QOL, including physical (impact of physical problems related to HIV), psychological (frequency of negative feelings), independence (necessity of medical treatment to function in daily life), social (feelings of acceptance), environmental (satisfaction with living conditions and medical care), and spiritual (fear of the future and death) among a sample of 74 PLWHA. Participants (72.9% male; mean age = 48.24, SD = 7.85) were recruited from AIDS Service Organizations in the United States. Results indicated that higher HIV symptom severity is significantly associated with lower physical and independence QOL, whereas higher emotion dysregulation is significantly associated with lower scores on all measured aspects of QOL. Additionally, results indicated that the interaction of emotion dysregulation and HIV symptom severity was significantly associated with both physical and environmental QOL. The form of the observed significant interactions indicated that HIV symptom severity was related to poorer QOL among those with lower (versus higher) emotion dysregulation. The present findings indicate that emotion dysregulation is related to QOL among PLWHA and may interact with HIV symptom severity to negatively impact certain aspects of QOL. Given the profound impact that HIV has on QOL, this finding is important in understanding these relations mechanistically, and may be important in the development of novel psychological treatment strategies.

Physical and mental component summary (PCS and MCS, respectively) scores generated using responses to the Short Form-12 (SF-12) survey were used to assess QOL at enrollment. Multivariable linear regression models determined independent predictors of QOL. Mean PCS and MCS scores were 36.7±11.7 and 42.4±12.2, respectively. Significant (P<0.05) negative impact on PCS scores in multivariable analyses was noted owing to constant mild-moderate pain with episodes of severe pain or constant severe pain (10 points), constant mild-moderate pain (5.2), pain-related disability/unemployment (5.1), current smoking (2.9 points), and medical co-morbidities. Significant (P<0.05) negative impact on MCS scores was related to constant pain irrespective of severity (6.8-6.9 points), current smoking (3.9 points), and pain-related disability/unemployment (2.4 points). In women, disability/unemployment resulted in an additional 3.7 point reduction in MCS score. Final multivariable models explained 27% and 18% of the variance in PCS and MCS scores, respectively. Etiology, disease duration, pancreatic morphology, diabetes, exocrine insufficiency, and prior endotherapy/pancreatic surgery had no significant independent effect on QOL. Constant pain, pain-related disability/unemployment, current smoking, and concurrent co-morbidities significantly affect the QOL in CP. Further research is needed to identify factors impacting QOL not explained by our analyses.

A decade of North American hospital restructuring in the 1990s resulted in the layoff of thousands of nurses, leading to documented negative consequences for both nurses and patients. Nurses who remained employed experienced significant negative physical and emotional health, decreased job satisfaction, and decreased opportunity to provide quality care. To develop a theoretical model of the impact of hospital restructuring on nurses and determine the extent to which emotionally intelligent nursing leadership mitigated any of these impacts. The sample was drawn from all registered nurses in acute care hospitals in Alberta, Canada, accessed through their professional licensing body (N = 6,526 nurses; 53% response rate). Thirteen leadership competencies (founded on emotional intelligence) were used to create 7 data sets reflecting different leadership styles: 4 resonant, 2 dissonant, and 1 mixed. The theoretical model was then estimated 7 times using structural equation modeling and the seven data sets. Nurses working for resonant leaders reported significantly less emotional exhaustion and psychosomatic symptoms, better emotional health, greater workgroup collaboration and teamwork with physicians, more satisfaction with supervision and their jobs, and fewer unmet patient care needs than did nurses working for dissonant leaders. Resonant leadership styles mitigated the impact of hospital restructuring on nurses, while dissonant leadership intensified this impact. These findings have implications for future hospital restructuring, accountabilities of hospital leaders, the achievement of positive patient outcomes, the development of practice environments, the emotional health and well-being of nurses, and ultimately patient care outcomes.

Unlike major depression, the psychosocial impact of dysthymia has received far less research attention. This study attempted to assess the psychosocial consequences of dysthymia. The sample consisted of 30 married patients with DSM-IV dysthymic disorder and a matched control group of 30 married patients with recurrent major depressive disorder (RDD), diagnosed using structured interviews. Apart from ratings of severity of depression, assessments of psychosocial impact included quality of life (QOL), disability, perceived social support and marital adjustment. Psychosocial parameters were evaluated using vernacular versions of well-validated scales previously used in similar populations. Matched normal/medically ill controls were derived from Indian studies which had assessed the same parameters using the same instruments. Patients with dysthymia were significantly impaired on measures of QOL, disability, social support and marital adjustment compared to normal/medically ill controls. On the other hand, the two groups of dysthymia and RDD were comparable on these measures apart from significantly lower social support among patients with dysthymia. Duration of illness and severity of depression emerged as the most important correlates, particularly of impaired QOL and disability levels. Small hospital-based sample, normal/medically ill controls derived from other studies and cross-sectional assessments were the major limitations. Dysthymia had considerable adverse psychosocial impact in terms of QOL, functioning (disability), social support and marital adjustment. Severity and chronicity appeared to be important mediators of this negative psychosocial impact. Increased awareness, improved recognition and adequate treatment might help negate some of the untoward social consequences of this condition.

Surviving childhood cancer has multiple implications on both physical and psychological domains of the individual. However, its study and possible effects on health-related quality of life (HRQoL) outcomes of adolescent survivors has been understudied. The objective of this study was twofold; to assess positive and negative cancer-related consequences (psychosocial and physical) in a sample of adolescent cancer survivors and to explore their relationship with HRQoL outcomes. Forty-one participants answered two questions about positive and negative consequences in the aftermath of cancer and filled in the KIDSCREEN-52 self-reported version. Data were analysed using mixed methods approach. Overall, 87.8% of the studied sample identified positive consequences and 63.4% negative consequences in survivorship. Four positive categories and five negative categories with regard to cancer-related consequences were found. Changed perspectives in life narratives seem to be the positive consequence more related to HRQoL (physical well-being, mood & emotions, autonomy, social support & peers), followed by useful life experience (physical well-being, autonomy, social support & peers). Psychological impact was the most referred negative consequence with a significant detrimental effect on social support and peers HRQoL dimension. Even if the majority of survivors reported benefit finding in the aftermath of cancer, concomitant positive and negative consequences have been found. However, findings only reveal a significant relationship between positive narratives and HRQoL, and negative consequences do not seem to have a significant influence on overall HRQoL in survivorship. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

In 2003 the ACGME implemented mandatory work-hour limitations to address concerns about the negative effects of sleep deprivation on resident wellbeing and patient safety. The night-float system (NFS) is an attempt to promote a balance between optimal patient care and well-rested residents. The aim of this study was to assess and compare the perceptions of surgical and non-surgical residents with regard to the impact of the NFS on their education, their well-being, and aspects related to patient care. After the approval from the Institutional Review Board was received, residents (241) from the UPR School of Medicine residency programs were invited to participate. Those residents who chose to take part in the study (149) completed a questionnaire with demographic questions and items related to individual perceptions of the impact of the NFS. The questionnaires, collected from April 2010 through September 2010, were categorized as having come from a surgical or nonsurgical resident. Data were analyzed. The response rate was almost sixty-two percent (61.8%). Of the residents who answered the questionnaire, 63% were in non-surgical programs, 51% were female, and 58% were single. Seventy-three percent of the residents had participated in an NFS. Sixty-two percent disagreed that their participation in the NFS improved their sense of well-being. Seventy-six percent agreed that their participation improved the continuity of care for the emergency room patients under their responsibility. A higher percentage of the non-surgical residents than surgical residents agreed that during their participation in the NFS, their relationships with their spouses/significant others and children (if applicable), sleep patterns and hours, peer support, and work/ rest balance were impacted negatively. This group of residents presented significant differences between the non-surgical and the surgical groups in areas related to well-being, which the majority agreed was negatively impacted during their participation in the NFS.

Small and Medium Enterprises (SMEs) in Malaysia have gained a prominent role as the significant contributor to the economic growth. However, the world nowadays is heading towards economic downturn. The stability of macroeconomic variables promotes profitability of SMEs which propels them to a stage where they can access financing for sustaining growth. Therefore, it is apparent that the behaviour of the macroeconomic variables plays a major part in determining the nation’s backbone in surviving the economic downturn. The objective of this study is to evaluate the impact of macroeconomic variables on the profitability of SMEs in Malaysia using multiple regression analysis. The findings revealed that the exchange rate has a small positive impact on SME GDP growth rate (10.81%), the interest rate has a strong positive impact (60.74%), while the inflation rate has a strong negative impact (-53.89%). Therefore, it can be concluded that the interest rate and inflation rate have significant impacts on the profitability of SMEs in Malaysia.

Adults with congenital heart disease seem to be more distressed than their healthy counterparts, which might render them even more susceptible to developing detrimental health outcomes. Previous research has confirmed the relationship between the perceived impact of stress on health and self-rated health. However, it remains unknown whether sense of coherence, a person's capacity to cope with stressors, moderates this relationship. This cross-sectional study aims to explore: the relationship between demographic and clinical characteristics, sense of coherence, and the perceived impact of stress on health; the relationship between the perceived impact of stress on health and self-rated health; and the moderating effect of sense of coherence in a sample of adults with congenital heart disease. Patients were recruited from the database of congenital and structural cardiology of a university hospital. The analytic sample included 255 patients (median age 35 years; 50% men). Data were obtained using self-report questionnaires and through medical record view. Univariate analyses and multiple regression analysis were conducted. The perceived impact of stress on health was negatively associated with sense of coherence (P<0.01), but there was no significant association with demographic or clinical characteristics. The perceived impact of stress on health and self-rated health were negatively associated (P<0.001), but sense of coherence did not moderate this relationship. Our findings support the need for further research on the perceived impact of stress on health. Such insights can be valuable for developing interventions aimed at reducing the negative health consequences of stress in patients with congenital heart disease. © The European Society of Cardiology 2015.

Research about self-harm in adolescence is important given the high incidence in youth, and strong links to suicide and other poor outcomes. Clarifying the impact of involvement in school-based self-harm studies on young adolescents is an ethical priority given heightened risk at this developmental stage. Here, 594 school-based students aged mainly 13-14 years completed a survey on self-harm at baseline and again 12-weeks later. Change in mood following completion of each survey, ratings and thoughts about participation, and responses to a mood-mitigation activity were analysed using a multi-method approach. Baseline participation had no overall impact on mood. However, boys and girls reacted differently to the survey depending on self-harm status. Having a history of self-harm had a negative impact on mood for girls, but a positive impact on mood for boys. In addition, participants rated the survey in mainly positive/neutral terms, and cited benefits including personal insight and altruism. At follow-up, there was a negative impact on mood following participation, but no significant effect of gender or self-harm status. Ratings at follow-up were mainly positive/neutral. Those who had self-harmed reported more positive and fewer negative ratings than at baseline: the opposite pattern of response was found for those who had not self-harmed. Mood-mitigation activities were endorsed. Self-harm research with youth is feasible in school-settings. Most young people are happy to take part and cite important benefits. However, the impact of participation in research appears to vary according to gender, self-harm risk and method/time of assessment. The impact of repeated assessment requires clarification. Simple mood-elevation techniques may usefully help to mitigate distress.

Ruminative (abstract verbal) processing during recall of aversive autobiographical memories may serve to dampen their short-term affective impact. Experimental studies indeed demonstrate that verbal processing of non-autobiographical material and positive autobiographical memories evokes weaker affective responses than imagery-based processing. In the current study, we hypothesized that abstract verbal or concrete verbal processing of an aversive autobiographical memory would result in weaker affective responses than imagery-based processing. The affective impact of abstract verbal versus concrete verbal versus imagery-based processing during recall of an aversive autobiographical memory was investigated in a non-clinical sample ( n  = 99) using both an observational and an experimental design. Observationally, it was examined whether spontaneous use of processing modes (both state and trait measures) was associated with impact of aversive autobiographical memory recall on negative and positive affect. Experimentally, the causal relation between processing modes and affective impact was investigated by manipulating the processing mode during retrieval of the same aversive autobiographical memory. Main findings were that higher levels of trait (but not state) measures of both ruminative and imagery-based processing and depressive symptomatology were positively correlated with higher levels of negative affective impact in the observational part of the study. In the experimental part, no main effect of processing modes on affective impact of autobiographical memories was found. However, a significant moderating effect of depressive symptomatology was found. Only for individuals with low levels of depressive symptomatology, concrete verbal (but not abstract verbal) processing of the aversive autobiographical memory did result in weaker affective responses, compared to imagery-based processing. These results cast doubt on the hypothesis that ruminative processing of aversive autobiographical memories serves to avoid the negative emotions evoked by such memories. Furthermore, findings suggest that depressive symptomatology is associated with the spontaneous use and the affective impact of processing modes during recall of aversive autobiographical memories. Clinical studies are needed that examine the role of processing modes during aversive autobiographical memory recall in depression, including the potential effectiveness of targeting processing modes in therapy.

Benefits of belonging: experimental manipulation of social inclusion to enhance psychological and physiological health parameters.

Acute changes in social belonging are important triggers for alterations in health and well-being, yet research has emphasised the negative effects of 'exclusion' at the expense of evaluating the potentially positive effects of 'inclusion'. This study examined the impact of acute belonging on physiological and psychological outcomes. A healthy population (N = 138) were randomly allocated to 'included' or 'excluded' conditions. Condition-dependent differences in pre/during-task heart rate and pre/post-task self-reports of negative/positive mood, and social self-esteem, were assessed. Included participants showed decreased heart rate and negative mood, and increased social self-esteem. No inclusion-related change in positive mood was shown. An increase in heart rate was observed in excluded participants though no changes in negative/positive mood or social self-esteem were shown. Shifts in social self-esteem acted as a mechanism through which inclusion/exclusion impacted upon negative and positive mood alterations. Results remained significant in presence of covariates (sex, global self-esteem, rumination and social anxiety). Findings suggest that acting to enhance belonging through 'inclusion' resulted in adaptive physiological and psychological outcomes. Neutral and potentially protective responses were observed in the immediate aftermath of 'exclusion'. Self-esteem served as one route through which these effects were transmitted.

Microplastics Affect Energy Balance and Gametogenesis in the Pearl Oyster Pinctada margaritifera.

Plastic pollution in the environment is increasing at global scale. Microplastics (MP) are derived from degradation of larger plastic items or directly produced in microparticles form (< 5 mm). Plastics, widely used in structures and equipment of pearl farming, are a source of pollution to the detriment of the lagoon ecosystem. To evaluate the impact of MP on the physiology of Pinctada margaritifera, a species of ecological and commercial interests, adult oysters were exposed to polystyrene microbeads (micro-PS of 6 and 10 μm) for 2 months. Three concentrations, 0.25, 2.5, and 25 μg L -1 , and a control were tested. Ingestion and respiration rate and assimilation efficiency were monitored on a metabolic measurement system to determine the individual energy balance (Scope For Growth, SFG). Effects on reproduction were also assessed. The assimilation efficiency decreased significantly according to micro-PS concentration. The SFG was significantly impacted by a dose-dependent decrease from 0.25 μg L -1 ( p < 0.0001), and a negative SFG was measured in oysters exposed to 25 μg L -1 . Gonads may have provided the missing energy to maintain animals' metabolism through the production of metabolites derived from germ cells phagocytosis. This study shows that micro-PS significantly impact the assimilation efficiency and more broadly the energy balance of P. margaritifera, with negative repercussions on reproduction.

Negative inferential style and deficits in emotional clarity have been identified as vulnerability factors for depression in adolescence, particularly when individuals experience high levels of life stress. However, previous research has not integrated these characteristics when evaluating vulnerability to depression. In the present study, a racially diverse community sample of 256 early adolescents (ages 12 and 13) completed a baseline visit and a follow-up visit 9 months later. Inferential style, emotional clarity, and depressive symptoms were assessed at baseline, and intervening life events and depressive symptoms were assessed at follow-up. Hierarchical linear regressions indicated that there was a significant three-way interaction between adolescents' weakest-link negative inferential style, emotional clarity, and intervening life stress predicting depressive symptoms at follow-up, controlling for initial depressive symptoms. Adolescents with low emotional clarity and high negative inferential styles experienced the greatest increases in depressive symptoms following life stress. Emotional clarity buffered against the impact of life stress on depressive symptoms among adolescents with negative inferential styles. Similarly, negative inferential styles exacerbated the impact of life stress on depressive symptoms among adolescents with low emotional clarity. These results provide evidence of the utility of integrating inferential style and emotional clarity as constructs of vulnerability in combination with life stress in the identification of adolescents at risk for depression. They also suggest the enhancement of emotional clarity as a potential intervention technique to protect against the effects of negative inferential styles and life stress on depression in early adolescence.

Community engagement is crucial to ongoing development and testing of sorely needed new biomedical HIV prevention technologies. Yet, negative trial results raise significant challenges for community engagement in HIV prevention trials, including the early termination of the Cellulose Sulfate microbicide trial and two Phase IIb HIV vaccine trials (STEP and Phambili). The present study aimed to explore the perspectives and experiences of civil society organization (CSO) representatives regarding negative HIV prevention trial results and perceived implications for future trials. We conducted in-depth interviews with 14 respondents from a broad range of South African and international CSOs, and analyzed data using thematic analysis. CSO representatives reported disappointment in response to negative trial results, but acknowledged such outcomes as inherent to clinical research. Respondents indicated that in theory negative trial results seem likely to impact on willingness to participate in future trials, but that in practice people in South Africa have continued to volunteer. Negative trial results were described as having contributed to improving ethical standards, and to a re-evaluation of the scientific agenda. Such negative results were identified as potentially impacting on funding for trials and engagement activities. Our findings indicate that trial closures may be used constructively to support opportunities for reflection and renewed vigilance in strategies for stakeholder engagement, communicating trial outcomes, and building research literacy among communities; however, these strategies require sustained resources for community engagement and capacity-building.

An Assessment of the Regional and National Socio-Economic Impacts of the 2007 Rift Valley Fever Outbreak in Kenya

2010-01-01

Although Rift Valley fever (RVF) has significant impacts on human health and livestock production, it can also induce significant (and often overlooked) economic losses among various stakeholders in the marketing chain. This work assesses and quantifies the multi-dimensional socio-economic impacts of the 2007 RVF outbreak in Kenya based on a rapid assessment of livestock value chains in the northeast part of the country and a national macroeconomic analysis. Although study results show negative impacts among producers in terms of food insecurity and reductions in income, we also found significant losses among other downstream actors in the value chain, including livestock traders, slaughterhouses, casual laborers, and butchers, as well as other, non-agricultural sectors. The study highlights the need for greater sensitivity and analyses that address the multitude of economic losses resulting from an animal disease to better inform policy and decision making during animal health emergencies.

Prolonged conflict and economic instability challenge the existing support networks in families and society places significant stress on both adults and adolescents. Exploring individual, family and social factors that increase the likelihood of or protect adolescents from negative outcomes are important to the development of evidence-based prevention and response programing in global settings. Examine the relationship between parent mental health and experience/perpetration of intimate partner violence (IPV) and adolescent behaviors, stigma, and school attendance. The relationship is further examined for differences by gender. Secondary analysis of data from an ongoing comparative effectiveness trial of a productive asset transfer program in eastern Democratic Republic of Congo (DRC). Three hundred and eighty-eight adolescent and parent dyads were included in the analysis. The analysis demonstrated that parent mental health and IPV can have a negative impact their children's well-being and the impact is different for boys and girls, likely linked to gender roles and responsibilities in the home and community. Social relationships of adolescents, as reported through experienced stigma, were negatively impacted for both boys and girls. Parent report of symptoms of PTSD and depression had a stronger negative effect on girls' outcomes, including experienced stigma, externalizing behaviors, and missed days of school than boys. For adolescent boys, their parent's report of IPV victimization/perpetration was associated with more negative behaviors at the 8-month follow-up assessment. The findings reinforce the critical importance of interventions that engage parents and their children in activities that advance health and improve relationships within the family.

Spanking, corporal punishment and negative long-term outcomes: a meta-analytic review of longitudinal studies.

Ferguson, Christopher J

2013-02-01

Social scientists continue to debate the impact of spanking and corporal punishment (CP) on negative child outcomes including externalizing and internalizing behavior problems and cognitive performance. Previous meta-analytic reviews have mixed long- and short-term studies and relied on bivariate r, which may inflate effect sizes. The current meta-analysis focused on longitudinal studies, and compared effects using bivariate r and better controlled partial r coefficients controlling for time-1 outcome variables. Consistent with previous findings, results based on bivariate r found small but non-trivial long-term relationships between spanking/CP use and negative outcomes. Spanking and CP correlated .14 and .18 respectively with externalizing problems, .12 and .21 with internalizing problems and -.09 and -.18 with cognitive performance. However, when better controlled partial r coefficients (pr) were examined, results were statistically significant but trivial (at or below pr = .10) for externalizing (.07 for spanking, .08 for CP) and internalizing behaviors (.10 for spanking, insufficient studies for CP) and near the threshold of trivial for cognitive performance (-.11 for CP, insufficient studies for spanking). It is concluded that the impact of spanking and CP on the negative outcomes evaluated here (externalizing, internalizing behaviors and low cognitive performance) are minimal. It is advised that psychologists take a more nuanced approach in discussing the effects of spanking/CP with the general public, consistent with the size as well as the significance of their longitudinal associations with adverse outcomes.

Background: This meta-analysis was conducted to evaluate whether HTR1A gene polymorphisms impact the efficacy of antipsychotic drugs in patients with schizophrenia. Methods: Candidate gene studies that were published in English up to August 6, 2015 were identified by a literature search of PubMed, Web of Science, and Google scholar. Data were pooled from individual clinical trials considering overall symptoms, positive symptoms and negative symptoms, and standard mean differences were calculated by applying a random-effects model. Results: The present meta-analysis included a total of 1281 patients from 10 studies. Three polymorphisms of HTR1A (rs6295, rs878567, and rs1423691) were selected for the analysis. In the pooled data from all studies, none of these HTR1A polymorphisms correlated significantly with either overall symptoms or positive symptoms. However, C allele carriers of the rs6295 polymorphism showed a significantly greater negative symptoms improvement than G allele carriers (P=.04, standardized mean difference =-0.14, 95％CI = 0.01 to 0.28). Conclusions: The results of our present analysis indicate that the HTR1A rs6295 polymorphism may impact negative symptoms improvement but not on either overall symptoms or positive symptoms improvement. However, this meta-analysis was based on a small number of studies and patients, and the effect size on negative symptoms was small. Given this limitation, the results should be confirmed by further investigations. PMID:26568455

This study aimed to investigate the prognostic significance of DSG3 and its association with response to neoadjuvant concurrent chemoradiotherapy (CCRT) in rectal cancer. Data mining of a publicly available dataset was performed to find genes associated with CCRT response. Immunohistochemistry was applied to evaluate DSG3 expression. The relationships between DSG3 expression and various clinicopathological parameters and survival were analyzed. The DSG3 gene was significantly associated with CCRT response. The expression of DSG3 negatively correlated with poorer tumor regression (p < 0.001) and had an independent negative impact on disease-specific survival (p = 0.011), local recurrence-free survival (p = 0.031) and metastasis-free survival (p = 0.029). DSG3 was a key prognostic factor and predictor for CCRT response in rectal cancer patients.

While there are many published studies on HIV and functional limitations, there are few in the context of early abuse and its impact on functionality and Quality of Life (QoL) in HIV. The present study focused on HIV in the context of childhood trauma and its impact on functionality and Quality of Life (QoL) by evaluating 85 HIV-positive (48 with childhood trauma and 37 without) and 52 HIV-negative (21 with childhood trauma and 31 without) South African women infected with Clade C HIV. QoL was assessed using the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), the Patient's Assessment of Own Functioning Inventory (PAOFI), the Activities of Daily Living (ADL) scale and the Sheehan Disability Scale (SDS). Furthermore, participants were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D) and the Childhood Trauma Questionnaire (CTQ). Subjects had a mean age of 30.1 years. After controlling for age, level of education and CES-D scores, analysis of covariance (ANCOVA) demonstrated significant individual effects of HIV status and childhood trauma on self-reported QoL. No significant interactional effects were evident. Functional limitation was, however, negatively correlated with CD4 lymphocyte count. In assessing QoL in HIV-infected women, we were able to demonstrate the impact of childhood trauma on functional limitations in HIV.

Introduction. Triple negative breast cancer (TNBC) is biologically aggressive and is associated with a worse prognosis. To understand the impact of race/ethnicity on outcome for patients with TNBC, confounding factors such as socioeconomic status (SES) need to be controlled. We examined the impact of race/ethnicity on a cohort of patients of low SES who have TNBC. Methods. 786 patients with Stage 0–III breast cancer were evaluated. Of these, 202 patients had TNBC (26%). Primary endpoints were cancer recurrence and death. ZIP code-based income tract and institutional financial data were used to assess SES. Data were analyzed using Kaplan-Meier survival analysis, log-rank tests, Cox Proportional hazard regression, chi square test, and t-tests. A P value ≤0.05 was considered statistically significant. Results. Of the 468 African-Americans (60%) in the database, 138 had TNBC; 64 of 318 Caucasians had TNBC. 80% of patients had an annual income of ≤$20,000. The 5-year overall survival was 77% for African-American women versus 72% for Caucasian women (P = 0.95). On multivariate analysis, race/ethnicity had an impact on disease-free survival (P = 0.027) but not on overall survival (P = 0.98). Conclusion. In a predominantly indigent population, race/ethnicity had no impact on overall survival for patients with triple negative breast cancer. PMID:22645687

Animal studies have demonstrated the interactive effects of prenatal stress exposure and postnatal rearing style on offspring capacity to manage stress. However, little is known about how parenting quality impacts the association between maternal prenatal anxiety and stress reactivity in human infants. This prospective study examined the impact of prenatal anxiety disorder and maternal caregiving sensitivity on infants' responses to a standardised interactive stressor (still-face procedure). Eighty-four women completed a clinical interview during pregnancy to assess anxiety symptoms meeting DSM-IV diagnostic criteria. At infant age 7 months, maternal sensitivity to infant distress and infant negative affect were observed and coded during the still-face procedure. Maternal postnatal (concurrent) anxiety and depression were also assessed at this time. Results indicated a negative association between maternal sensitivity to infant distress and infant negative affect responses to the still-face procedure. An unexpected finding was a positive association between parity and infant reactivity. The main effect for sensitivity was qualified by a significant interaction, p<.05, suggesting that the impact of sensitivity was particularly marked among infants of women who experienced an anxiety disorder during pregnancy. This finding is consistent with a cumulative risk model suggesting that maternal prenatal anxiety and quality of maternal care act in concert to shape infant outcomes. Copyright © 2010 Elsevier Inc.

The aim of this study is to examine the impact of air pollutants, including mono-nitrogen oxides (NOx), nitrous oxide (N 2 O), sulfur dioxide (SO 2 ), carbon dioxide emissions (CO 2 ), and greenhouse gas (GHG) emissions on ecological footprint, habitat area, food supply, and biodiversity in a panel of thirty-four developed and developing countries, over the period of 1995-2014. The results reveal that NOx and SO 2 emissions both have a negative relationship with ecological footprints, while N 2 O emission and real GDP per capita have a direct relationship with ecological footprints. NOx has a positive relationship with forest area, per capita food supply and biological diversity while CO 2 emission and GHG emission have a negative impact on food production. N 2 O has a positive impact on forest area and biodiversity, while SO 2 emissions have a negative relationship with them. SO 2 emission has a direct relationship with per capita food production, while GDP per capita significantly affected per capita food production and food supply variability across countries. The overall results reveal that SO 2 , CO 2 , and GHG emissions affected potential habitat area, while SO 2 and GHG emissions affected the biodiversity index. Trade liberalization policies considerably affected the potential habitat area and biological diversity in a panel of countries. Copyright © 2017 Elsevier Inc. All rights reserved.

Impact of Sexual Coercion on Romantic Experiences of Adolescents and Young Adults

2014-01-01

Little is known about the effect of sexual coercion on romantic relationship quality and dating experiences. The current study aimed to address this dearth in the literature and test the hypothesis that sexual coercion has a negative impact on victims’ subsequent romantic experiences. Using a sample of 94 youth (44 males and 50 females), the current study addressed the impact of sexual coercion on romantic relationship quality and dating experiences. Tracking youth for 8.5 years (M age at Wave 1 = 15.10 years, SD = .49), the current study used piecewise growth curve modeling to account for shifts in the intercept and slope of romantic experiences following sexual coercion. Negative interactions immediately increased following coercion and continued to have an accelerated rate of growth (i.e., a slope change). Jealousy in romantic relationships increased in slope. Serious dating decelerated following the coercive incident. Results were largely consistent across gender and severity of the coercive incident. Contrary to hypotheses, relational support, relationship satisfaction, and casual dating did not significantly change following sexual coercion. Consistent with hypotheses, sexual coercion had a negative impact on romantic experiences. These findings have clinical implications for both prevention and intervention around sexual violence. In addition, the consistency of findings across gender and severity suggests that increased focus should be directed toward both male sexual coercion and less severe sexual coercion. PMID:24519107

Aims We aimed to evaluate the prognostic value of routine use of PCR amplification of immunoglobulin gene rearrangements in bone marrow (BM) staging in patients with follicular lymphoma (FL). Methods Clonal rearrangements were assessed by immunoglobulin heavy and light-chain gene rearrangement analysis in BM aspirates from 96 patients diagnosed with FL and related to morphological detection of BM involvement in biopsies. In 71 patients, results were also compared with concurrent flow cytometry analysis. Results BM involvement was detected by PCR in 34.4% (33/96) of patients. The presence of clonal rearrangements by PCR was associated with advanced clinical stage (I–III vs IV; p<0.001), high FL International Prognostic Index (FLIPI) score (0–1, 2 vs ≥3; p=0.003), and detection of BM involvement by morphology and flow cytometry analysis (p<0.001 for both). PCR-positive patients had a significantly poorer survival than PCR-negative patients (p=0.001, log-rank test). Thirteen patients positive by PCR but without morphologically detectable BM involvement, had significantly poorer survival than patients with negative morphology and negative PCR result (p=0.002). The poor survival associated with BM involvement by PCR was independent of the FLIPI score (p=0.007, Cox regression). BM involvement by morphology or flow cytometry did not show a significant impact on survival. Conclusions Our results showed that routine use of PCR-based clonality analysis significantly improved the prognostic impact of BM staging in patients with FL. BM involvement by PCR was also an independent adverse prognostic factor. PMID:25233852

Personality dimension negative emotionality is known to be associated with academic achievement. The present study focuses on the influence of negative emotionality (neuroticism) on the medical students’ academic achievements. The main objective of this study was to ascertain the negative emotionality scores among the first year Malaysian medical students studying in Malaysia and India, further to find out the association between negative emotionality and their academic achievements. The current study sample includes 60 first year Malaysian medical students from Universiti Sultan Zainal Abidin, Malaysia, and USM-KLE IMP, Belgaum, India. They were selected by convenient sampling technique. The Medico-Psychological questionnaire was used to find out the negative emotionality scores among the students and these scores were compared with academic scores. The data were analyzed using SPSS- 20. Thus, the study result goes with the prediction that there is a significant correlation between academic achievement and negative emotionality. We concluded that negative emotionality has a negative impact on medical student’s academic achievement regardless of the fact whether they study in their own country or overseas. PMID:27354836

Studies quantifying relationships between floods and diarrheal diseases have mainly been conducted in low-latitude regions. It's therefore increasingly important to examine these relationships in midlatitude regions, where they may have significant public health implications. This study aimed to examine the association between floods and bacillary dysentery in the city of Dalian, China. A generalized additive mixed model was applied to examine the association between floods and bacillary dysentery. The relative risk (RR) of flood impact on bacillary dysentery was estimated. A total of 18,976 cases of bacillary dysentery were reported in Dalian during the study period. Two weeks' lagged effect was detected from the impact of floods on bacillary dysentery. The RR of flood impact on bacillary dysentery was 1.17 (95% CI: 1.03-1.33). Floods have significantly increased the risk of bacillary dysentery in Dalian. More studies should focus on the association between floods and infectious diseases in different regions. Our findings have significant implications for managing the negative health impact of floods in the midlatitude region of China. (Disaster Med Public Health Preparedness. 2017;11:190-195).

The impact of husband physical aggression and alcohol use on marital functioning: does alcohol "excuse" the violence?

PubMed

Testa, M; Leonard, K E

2001-10-01

Alcohol has been posited to serve as an "excuse" for deviant behavior, including domestic violence. A recent study suggested that wives hold husbands less responsible for their aggressive behavior when husbands are problem drinkers. To replicate and extend this study, the independent and interactive effects of husband physical aggression and husband alcohol use on wives' marital satisfaction and thoughts of divorce were examined among newlywed couples (n = 387). Husband physical aggression had a significant negative effect on marital satisfaction and a significant positive effect on divorce ideation regardless of the measure of husband alcohol use employed. Alcohol dependence had a negative effect on satisfaction; however, in no case was there an interaction between alcohol and aggression. Results fail to replicate an earlier study supporting an excuse function of alcohol and suggest that alcohol does not mitigate the negative effects of domestic violence on marital functioning.

The effect of targeting tolerance of children's negative emotions among anxious parents of children with anxiety disorders: A pilot randomised controlled trial.

Following cognitive behavioural therapy for child anxiety a significant minority of children fail to lose their diagnosis status. One potential barrier is high parental anxiety. We designed a pilot RCT to test claims that parental intolerance of the child's negative emotions may impact treatment outcomes. Parents of 60 children with an anxiety disorder, who were themselves highly anxious, received either brief parent-delivered treatment for child anxiety or the same treatment with strategies specifically targeting parental tolerance of their child's negative emotions. Consistent with predictions, parental tolerance of the child's negative emotions significantly improved from pre- to post-treatment. However, there was no evidence to inform the direction of this association as improvements were substantial in both groups. Moreover, while there were significant improvements in child anxiety in both conditions, there was little evidence that this was associated with the improvement in parental tolerance. Nevertheless, findings provide important clinical insight, including that parent-led treatments are appropriate even when the parent is highly anxious and that it may not be necessary to adjust interventions for many families.

The impact of assumed knowledge entry standards on undergraduate mathematics teaching in Australia

NASA Astrophysics Data System (ADS)

King, Deborah; Cattlin, Joann

2015-10-01

Over the last two decades, many Australian universities have relaxed their selection requirements for mathematics-dependent degrees, shifting from hard prerequisites to assumed knowledge standards which provide students with an indication of the prior learning that is expected. This has been regarded by some as a positive move, since students who may be returning to study, or who are changing career paths but do not have particular prerequisite study, now have more flexible pathways. However, there is mounting evidence to indicate that there are also significant negative impacts associated with assumed knowledge approaches, with large numbers of students enrolling in degrees without the stated assumed knowledge. For students, there are negative impacts on pass rates and retention rates and limitations to pathways within particular degrees. For institutions, the necessity to offer additional mathematics subjects at a lower level than normal and more support services for under-prepared students impacts on workloads and resources. In this paper, we discuss early research from the First Year in Maths project, which begins to shed light on the realities of a system that may in fact be too flexible.

Distinct mechanisms for the impact of distraction and interruption on working memory in aging

PubMed Central

Clapp, Wesley C; Gazzaley, Adam

2010-01-01

Interference is known to negatively impact the ability to maintain information in working memory (WM), an effect that is exacerbated with aging. Here, we explore how distinct sources of interference, i.e., distraction (stimuli to-be-ignored) and interruption (stimuli requiring attention), differentially influence WM in younger and older adults. EEG was recorded while participants engaged in three versions of a delayed-recognition task: no interference, a distracting stimulus, and an interrupting stimulus presented during WM maintenance. Behaviorally, both types of interference negatively impacted WM accuracy in older adults significantly more than younger adults (with a larger deficit for interruptions). N170 latency measures revealed that the degree of processing both distractors and interruptors predicted WM accuracy in both populations. However, while WM impairments could be explained by excessive attention to distractors by older adults (a suppression deficit), impairment induced by interruption were not clearly mediated by age-related increases in attention to interruptors. These results suggest that distinct underlying mechanisms mediate the impact of different types of external interference on WM in normal aging. PMID:20144492

During an environmental impact study of an accidental oil spill in the Campeche Sound in October 2007, we examined the helminth parasites of the benthic flatfish Cyclopsetta chittendeni as well as the concentrations of hydrocarbons and heavy metals in the sediment. The aim of this study was to determine the potential effects of these contaminants on the helminth communities of the flatfish. A total of 427 hosts were examined, and 16,895 helminths, representing 17 species, were obtained from two surveys (March and July, 2008). Statistically significant negative associations were observed between the hydrocarbons and helminth parasite abundances using multivariate methods. The results suggest that in October 2007, the oil spill had a strong negative effect on these helminth communities. However, after five months, the impacted stations were re-populated by both the flatfish and helminths. The most likely explanation for this rapid recovery is the rescue effect from non-impacted habitats to impacted stations. Copyright © 2015 Elsevier Inc. All rights reserved.

Positive and negative psychological impact after secondary exposure to politically motivated violence among body handlers and rehabilitation workers.

2008-12-01

The positive and negative psychological impact of secondary exposure to politically motivated violence was examined among body handlers and hospital rehabilitation workers, 2 groups that differed in their proximity and immediacy to violent events. Survivors of politically motivated violence served as a comparison group. Body handlers experienced high levels of positive psychological impact and traumatic stress symptoms. Levels of positive psychological impact among on-scene body handlers were higher than those experienced by rehabilitation workers. Traumatic stress symptoms predicted positive psychological impact among body handlers. These findings indicate that proximity to stressors is associated with higher levels of positive and negative psychological impact. Physical proximity is a major contributory factor to both positive and negative psychological effects of secondary exposure to trauma.

Personality disorder and treatment outcome in alcohol use disorder.

PubMed

Newton-Howes, Giles; Foulds, James

2018-01-01

As personality disorder impacts the outcome of most major mental disorders, it would be consistent for it to impact negatively on the outcome of alcohol use disorders (AUDs). This update is to provide an up-to-date overview of the recent literature examining the impact of personality disorder and personality traits on the treatment outcome of AUDs. Comorbidity between personality disorder and AUD is significant and approaches 50%. Patients with AUD and comorbid personality disorder are substantially less likely to remain in treatment, drink more per drinking day and drink more frequently. If retained in treatment, comorbidity does not, however, lead to poorer outcomes. Relapse to drinking is more common in patient with high novelty seeking and lower reward dependence and persistence. Reporting from most studies is of moderate-to-poor quality and a single high-quality study may alter these findings. Landmark alcohol studies are notably quiet on the impact of personality on AUD treatment outcome. Both personality disorder and higher novelty seeking impact negatively on the treatment outcome of AUD. As personality disorder is common in this group, clinicians engaged in AUD treatment should screen for personality disturbance, either disorder or high novelty seeking.

The perceived impact of cancer on quality of life for post-treatment survivors of childhood cancer.

PubMed

Zebrack, Brad J; Landier, Wendy

2011-12-01

To examine whether childhood cancer survivors' perceptions of the impact of cancer are related to quality of life (QOL) and psychological distress. 621 survivors (aged 18-39 years) completed a mailed survey assessing distress and QOL. Hierarchical linear regression models analyzed the independent effects of perceived impacts of cancer on distress and QOL and the extent to which positive and negative perceptions attenuated the effects of covariates on outcomes. After accounting for perceptions of cancer's impact on their lives, employment/occupation status, marital/relationship status, and health problems were observed to be significant predictors of QOL and distress. Psychological distress and the mental health component of QOL appeared to be less influenced by sociodemographic status and health problems and more a function of how survivors perceive cancer as impacting their lives. Results suggest that distress and QOL are partially a function of survivors' perceptions of how cancer has affected them and continues to affect them in both positive and negative ways. Future research is needed to examine combinations of pharmacological, psychological and/or social interventions that are likely to result in better outcomes in this population.

Enzootic bovine leukosis (EBL) is an economically important disease of dairy cattle caused by bovine leukemia virus (BLV). The economic impacts of the infection have been debated in the literature. The present study was conducted to determine the lifetime effects of BLV infection on longevity and milk production of dairy cows in Canada. The data were aggregated from a combination of two data sets: 1) BLV serum-ELISA test results from Canada-wide surveys of production limiting diseases, which took place between 1998 and 2003 in 8 provinces, and 2) longitudinal production data for all cows in the former study, extracted from the Canadian dairy herd improvement database. All participant cows had been culled or died by the onset of this study. A historical cohort study was designed, including cows which tested positive to BLV-antibodies in their first lactation (positive cohort, n=1858) and cows which tested negative in their second or later lactations (negative cohort, n=2194). To assess the impacts of infection with BLV on longevity (the number of lifetime lactations), a discrete-time survival analysis was carried out. The effect of BLV on the lifetime milk production (the sum of all life 305-day milk production) was evaluated using a multilevel linear regression model. Overall, 4052 cows from 348 herds met the eligibility criteria and were enrolled in the study. In the longevity model, the interaction term between time (lactation number) and BLV-status was highly significant. Cows which were positive to BLV had consistently greater probabilities of being culled (or dying) than the test-negative cows. In the milk production model, the interaction term between BLV-status and longevity of the cows was highly significant; indicating that lifetime BLV effects on the total milk production was dependent on the lactation in which the study cows were culled/died. Infected cows with 2 and 3 lactations showed significantly lower life milk productions [-2554kg (-3609 to -1500) and -1171kg (-2051 to -292), respectively] compared with their negative counterparts with 2 and 3 lactations. As the cows lived longer (>3 lactations), the differences in life milk production between the two cohorts were no longer significant. Overall, it was predicted that the test-positive cows produced substantially lower milk compared to the test-negative cows throughout their study lifespans. With the high prevalence of BLV in Canadian dairy cows and its detrimental economic impacts, pursuing broad-based control programs in Canada should be evaluated. Copyright © 2016 Elsevier B.V.

Hooking up is a normative behavior among college students that is associated with a range of positive and negative consequences. While previous research has primarily focused on women's negative experiences of hooking up, the current study explored the relationships among hooking up behaviors, psychological distress, and a broad range of negative effects of hooking up in both male and female college students. Using a multisite sample of college students, we developed the 14-item Negative Impact of Hookups Inventory (NIHI) to assess negative health outcomes, emotional responses, and social consequences associated with hooking up. Unprotected sex and having more hookup partners were associated with greater negative experiences of hooking up. Contrary to expectations, there were no gender differences in the total number of negative hookup effects, although men reported more frequent hookups. In addition, negative impacts of hooking up were positively associated with psychological distress regardless of gender. The NIHI may offer a useful tool to assess the negative impacts of hooking up. Understanding students' hookup experiences is an important step toward developing targeted health interventions related to hooking up behavior in young adult populations.

Despite the growing body of evidence that suggests dyslexia persists through the life span, there is a dearth of research that explores the complicating factor of dyslexia in late adulthood. Based upon stress and coping theory, this study examined whether perceived family support protects the impact of negative emotional experience with dyslexia on self-esteem. Adults aged 21 years and older with diagnosed or self-reported dyslexia were participants in a web-based survey. A total of 224 individuals completed the survey. These findings are from the 50 participants who reported to be 60 years or older. Completed measures include their perception of family support, emotional experience with dyslexia, self-esteem, and demographic variables. Preliminary analysis revealed that negative emotional experience with dyslexia negatively impacts self-esteem. Hierarchical moderated regression analysis demonstrated that positive perceived family support significantly buffers, mitigates, and protects the effects of negative emotional experiences with dyslexia on self-esteem in individuals with dyslexia in late adulthood. In this study, family support promoted self-esteem because as a protective dynamic, it helped older adults cope with the emotional distress associated with dyslexia. Implications of these findings are discussed.

1977-01-01

Interaction between the solar sail and the natural plasma environment were examined for deleterious impacts upon the operation of the sail and its associated payload. Electrostatic charging of the sail in the solar wind and in near earth environment were examined. Deployment problems were studied. An analysis of electromechanical oscillations coupling the sail to the natural plasma was performed. As a result of these studies, it was concluded that none of these effects will have a significant negative impact upon the sail operation. The natural environment will be significantly perturbed and this will preclude measurements of electric and magnetic fields from an attached payload.

Understanding the Role of Self-Judgment in the Association between Body Dissatisfaction and Quality of Life on Normal-Weight and Overweight Portuguese Women.

Literature has demonstrated the negative impact of body image dissatisfaction on women's quality of life. Nonetheless, it has been suggested that the relationship between body dissatisfaction and women's well-being is not linear, and that the processes that mediate this association remain unclear. This study aims to clarify the mediator role of self-judgment in the association between negative body image and psychological quality of life, in two groups: normal-weight and overweight women. This cross-sectional study comprised 200 normal-weight and 92 overweight female college students, aged between 18 and 24 years old, that completed self-report instruments of body dissatisfaction, self-judgment, and quality of life. Results showed that women who presented harsher self-judgment about their perceived failures tended to present lower levels in all quality of life domains. Also, results from mediation analyses indicated the relationship between body dissatisfaction and psychological quality of life was significantly mediated by the mechanisms of self-judgment in the two BMI groups (95% CI [-2.41 to -0.04]; 95% CI [-6.35 to -.89]). This mediational model accounted for 28.3% and 40.7% of psychological quality of life in the normal-weight and overweight groups, respectively. These results suggest that a lower ability to deal with one's failures or inadequacies (e.g., negative evaluation of body image) in a kind and accepting manner may significantly increase the negative impact of body dissatisfaction on one's psychological quality of life. In this way, it seems that, the focus of interventions should go beyond body dissatisfaction and also target the development of adaptive attitudes (opposed to self-critical attitudes) to deal with negative body-related experiences.

The health-related quality of life (HRQoL) is a matter of concern in elderly people with chronic diseases. The objective of this study was to investigate the impact of obesity, hypertension and diabetes on HRQoL among elderly. A population based cross sectional study was conducted with 750 representative sample of elderly people aged 60-90 years in Babol, the northern Iran. The demographic data and the measurement of blood pressure and other anthropometric measures were collected. The validated short form (SF-36) questionnaire was used to assess the HRQoL. A multiple linear regression model was applied to assess the impact of obesity, abdominal obesity, hypertension and diabetes on QoL. The mean age (SD) of participants was 68.0±7.6 and 67.7±7.9 years for men and women respectively. Diabetes exerted the most negative effect on QoL score (adjusted coefficient=-9.2, 95% CI: -11.7, -6.5 points) followed by abdominal obesity and hypertension. Whereas a combination of three conditions was associated with a greater significant reduction in QoL scores in both sexes(adjusted coefficient=-14.5, 95% CI: -19.0, -9.9 points). However, the negative influence of obesity and hypertension on QoL was significant only in women. Most components of the QoL is affected by diabetes, obesity and hypertension particularly in women. Diabetes alone or in combination with other conditions has a negative influence in both sexes with greater effect in women. These findings justify further professional support to compensate the negative influences chronic conditions on health-related QoL especially for older obese diabetic women.

2011-01-01

Stone removal can improve renal function by eradicating obstruction and, in certain cases, an underlying infection. Stone-removing procedures, however, may negatively impact functional integrity. Many things may impact the latter, including the procedures used, the methods of assessing function, the time when these assessments are made, the occurrence of complications, the baseline condition of the kidney, and patient-related factors. In the majority of cases, little significant functional impairment occurs. However, there are gaps in our knowledge of this subject, including the cumulative effects of multiple procedures violating the renal parenchyma and long-term functional outcomes. PMID:21935339

Formation of negative hydrogen ion: polarization electron capture and nonthermal shielding.

PubMed

Ki, Dae-Han; Jung, Young-Dae

2012-09-07

The influence of the nonthermal shielding on the formation of the negative hydrogen ion (H(-)) by the polarization electron capture are investigated in partially ionized generalized Lorentzian plasmas. The Bohr-Lindhard method has been applied to obtain the negative hydrogen formation radius and cross section as functions of the collision energy, de Broglie wave length, Debye length, impact parameter, and spectral index of the plasma. The result shows that the nonthermal character of the plasma enhances the formation radius of the negative hydrogen, especially, for small Debye radii. It is found that the nonthermal effect increases the formation cross section of the negative hydrogen. It is also found that the maximum position of the formation cross section approaches to the collision center with an increase of the spectral index. In addition, it is found that the formation cross section significantly decreases with an increase of the Debye length, especially, for small spectral indices.

The present study examined the unique impact of perceived negativity in multiple social relationships on endocrine and inflammatory responses to a laboratory stressor. Via hierarchical cluster analysis, those who reported negative social exchanges across relationships with a romantic partner, family, and their closest friend had higher mean IL-6 across time and a greater increase in TNF-α from 15 min to 75 min post stress. Those who reported negative social exchanges across relationships with roommates, family, and their closest friend showed greater IL-6 responses to stress. Differences in mean IL-6 were accounted for by either depressed mood or hostility, whereas differences in the cytokine stress responses remained significant after controlling for those factors. Overall, this research provides preliminary evidence to suggest that having multiple negative relationships may exacerbate acute inflammatory responses to a laboratory stressor independent of hostility and depressed mood.

Wong, Hung

2006-01-01

Based on a sample survey, this paper, analyzes the impact of human capital, social capital and social exclusion on the opportunity of Hong Kong families with youth members to leave poverty. Educational attainment of the youth members and adult family members, as well as the quantity and quality of social networks were found to have significant positive impacts, while social exclusion from the labor market of the adult members was found to have significant negative impact on their opportunity to leave poverty. Among all factors, quality of social network is the most influential. The author suggests that in order to help families out of poverty and enable positive development of youth members, poverty alleviation policies or programs should be targeted to help the youth in poor families to build up a quality social network.

Change management of mergers: the impact on NHS staff and their psychological contracts.

PubMed

Cortvriend, Penny

2004-08-01

The NHS has experienced a significant amount of organisational change and restructuring, which has included numerous mergers and de-mergers, since the Labour party came to power in the UK in 1997. However, to date there has been little in the way of evaluation of such changes, particularly the impact of organisational restructuring on the staff involved. This paper examines the human aspect of a merger, and subsequent de-merger, within a primary care trust (PCT) in the North of England, using a focus group methodology. The findings demonstrate that leadership and management styles have a significant impact on staff experiencing such changes. In addition, the psychological contract can be damaged due to the impact of several factors, inducing exit or intention to leave. Employees experienced a constant cycle of change with little time for stabilisation or adjustment, leading to negativity and lowered motivation at times.

2010-09-01

Over the past 50 years, significant improvements in cardiac surgical care have been achieved. Nevertheless, surgical errors that significantly impact patient safety continue to occur. In order to further improve surgical outcomes, patient safety programs must focus on rectifying work system factors in the operating room (OR) that negatively impact the delivery of reliable surgical care. The goal of this paper is to provide an integrative review of specific work system factors in the OR that may directly impact surgical care processes, as well as the subsequent recommendations that have been put forth to improve surgical outcomes and patient safety. The important role that surgeons can play in facilitating work system changes in the OR is also discussed. The paper concludes with a discussion of the challenges involved in assessing the impact that interventions have on improving surgical care. Opportunities for future research are also highlighted throughout the paper. 2010 Elsevier Ltd. All rights reserved.

2017-03-01

There is research suggesting that binge eating may serve an affect regulation function. However, experimental evidence supporting this model in adults is sparse and studies have been mixed regarding whether negative affect impacts objective energy intake. This study examined the impact of a real-time interpersonal stressor on laboratory test meal intake between individuals endorsing recent objective binge eating (≥1×/week) and those denying disordered eating. Generalized linear modeling was used to compare individuals with recent binge eating (BE group; n = 52) to those denying recent eating pathology (HC group; n = 51) on test meal intake following a stressor (stressful condition) or neutral stimulus (non-stressful condition). Moderated mediation analyses were used to examine whether negative affect mediated the impact of condition on intake differently between BE and HC groups. The BE group did not have significantly higher energy intake than the HC group in the stressful verses non-stressful condition. However, the BE group was more likely to engage in extreme intake (i.e., over- or under-consumption) than the HC group in the stressful versus non-stressful condition (p = 0.02). Changes in negative affect did not significantly mediate the relationship between condition and intake extremes for the BE group. The results indicate that both over- and under-consumption are triggered by stress among individuals with recent binge eating. Continued research investigating both binge eating and restriction as a means of affect regulation in binge-eating samples is encouraged. Copyright © 2016 Elsevier Ltd. All rights reserved.

Fungal endosymbionts in plants may influence interactions among plants, herbivores and their parasitoids through the production of secondary metabolites. We used a lepidopteran pest and its generalist parasitoid to test the effect of endophyte-infected plants on a third trophic level. Endophytic fungi, Aspergillus flavus and Aspergillus niger, isolated from Acacia arabica, were used to infect cauliflower plants. We found that the presence of the endophyte in the plants significantly extended the development period of Spodoptera litura (Fab.) larvae. Feeding of the host on endophyte-infected plants further adversely affected the development and performance of its parasitoid, Bracon hebetor (Say). A negative impact was also recorded for longevity and fecundity of endophyte-naive parasitoid females due to the parasitization of host larvae fed on endophyte-infected plants. The presence of endophytes in the diet of the host larvae significantly prolonged the development of the parasitoid. A strong detrimental effect was also recorded for larval survival and emergence of parasitoid adults. The longevity and parasitism rate of female wasps were reduced significantly due to the ingestion of endophyte-infected cauliflower plants by S. litura larvae. Overall, we found that both endophytic fungi had a negative impact on the parasitoid.

A direct negative link between human health and urban pollution levels generated by increased internal levels of oxyradicals is well established. The impact of urban environment on the physiology of wild birds is however, poorly investigated. Here we compare oxidative damage (i.e., lipid peroxidation, measured as TBARS) and different antioxidant enzymes (glutathione reductase (GR), glutathione-S-transferase (GST), and catalase (CAT)) in lungs of urban and rural great tits, Parus major. In addition, we investigated enzymatic (i.e., CAT) and non-enzymatic (i.e., carotenoids) antioxidant levels in liver tissue. There was no significant difference in lipid peroxidation in lungs between the environments. Among the antioxidant enzymes measured in lungs, only CAT showed a tendency towards increased activity in the urban environment. In contrast, CAT in livers was highly non-significant. However, there was a significantly higher concentration of dietary carotenoids (i.e., lutein (Lut) and zeaxanthin (Zx)) in urban males, along with a sex-specific difference in composition (Lut:Zx ratio) between the environments. Taken together, these results suggest that great tit lungs and livers do not seem to be negatively affected, regarding oxidative stress, by living in an urban environment.

Psychological and organizational impact of bullying over and above negative affectivity: a survey of two nursing contexts.

Limited research exists on the impact of bullying across psychological and/or organizationally orientated outcomes for nurses working within different nursing contexts. Research that has explored these outcomes has not considered the potential confounding effects of negative affectivity (NA). This study's aim was to examine the extent hospital and aged care nurses are impacted by bullying on these outcomes, while considering NA. A total of 267 hospital nurses/midwives and 168 aged care nurses from an Australian healthcare organization responded to a survey. The results revealed hospital nurses/midwives who experienced bullying reported higher levels of psychological distress, as well as lower commitment and job satisfaction levels. Aged care nurses who experienced bullying reported lower levels of well-being and commitment. NA was a significant covariate for most analyses. Thus, nurses across these contexts are affected by bullying in relation to psychological and organizational-orientated outcomes over and above the effects of NA, particularly for commitment. © 2013 Wiley Publishing Asia Pty Ltd.

Biodiversity conservation and armed conflict: a warfare ecology perspective.

PubMed

Hanson, Thor

2018-04-23

The activities involved in preparing for, executing, and recovering from armed conflict are globally pervasive and consequential, with significant impacts on natural systems. Effects on biodiversity are predominantly negative, produced by direct and indirect battlefield impacts, as well as the general breakdown of social, economic, and governance systems during wartime. Certain conservation opportunities do occur, however, particularly on lands set aside for training exercises, buffer zones, and peace parks. Here, the relationship between armed conflict and biodiversity is reviewed using the temporal framework of warfare ecology, which defines warfare as an ongoing process of three overlapping stages: preparations, war (armed conflict), and postwar activities. Several themes emerge from recent studies, including a heightened awareness of biodiversity conservation on military lands, the potential for scientific and conservation engagement to mitigate negative biodiversity impacts in war zones, and the importance of the postwar period for incorporating biodiversity priorities into reconstruction and recovery efforts. Research limitations and knowledge gaps are also discussed. © 2018 New York Academy of Sciences.

Investigations of workplace bullying in health care settings have tended to focus on nurses or other clinical staff. However, the organizational and power structures enabling bullying in health care are present for all employees, including administrative staff. : The purpose of this study was to specifically focus on health care administration staff and examine the prevalence and consequences of workplace bullying in this occupational group. A cross-sectional study was conducted based on questionnaire data from health care administration staff who work across facilities within a medium to large health care organization in Australia. The questionnaire included measures of bullying, negative affectivity (NA), job satisfaction, organizational commitment, well-being, and psychological distress. The three hypotheses of the study were that (a) workplace bullying will be linked to negative employee outcomes, (b) individual differences on demographic factors will have an impact on these outcomes, and (c) individual differences in NA will be a significant covariate in the analyses. The hypotheses were tested using t tests and analyses of covariances. A total of 150 health care administration staff completed the questionnaire (76% response rate). Significant main effects were found for workplace bullying, with lower organizational commitment and well-being with the effect on commitment remaining over and above NA. Main effects were found for age on job satisfaction and for employment type on psychological distress. A significant interaction between bullying and employment type for psychological distress was also observed. Negative affectivity was a significant covariate for all analyses of covariance. The applications of these results include the need to consider the occupations receiving attention in health care to include administration employees, that bullying is present across health care occupations, and that some employees, particularly part-time staff, may need to be managed slightly differently to the full-time workforce.

Although extensive research has been conducted on both smoking and low exercise capacity alone, few studies have examined the joint impact or interaction of these two risk factors. We examined the joint and interactive effects of smoking and self-reported exercise capacity on subsequent clinical events (heart failure, myocardial infarction [MI], stroke, and cardiovascular-related mortality) among women with suspected myocardial ischemia. At baseline (1996-1999), 789 women completed angiographic testing of coronary artery disease (CAD) severity and provided self-report information about their smoking history and exercise capacity as well as demographic and other risk factor data. Incidence of clinical events among the women was tracked for a median of 5.9 years; this analysis was conducted in 2008. In an adjusted survival analysis, women with a positive smoking history and self-reported low exercise capacity had the greatest risk of experiencing a clinical event (HR = 7.7, 95% CI 2.3, 25.5), followed by women with a positive smoking history and self-reported high exercise capacity (HR = 6.9, 95% CI 2.0, 24.6) and those with a negative smoking history and self-reported low exercise capacity (HR = 4.9, 95% CI 1.5, 15.8), relative to women with a negative smoking history and self-reported high exercise capacity. Additional analyses revealed a significant interaction between smoking history and exercise capacity, such that (1) women with a positive smoking history did not experience an additional significantly greater risk due to low exercise capacity, unlike those with a negative smoking history, and (2) all women experienced a significantly greater risk due to a positive smoking history regardless of their exercise capacity. Among women with suspected myocardial ischemia, the combined protective health effects of self-reported high exercise capacity and a negative smoking history remained significant after controlling for preexisting CAD severity and other established risk factors. These findings highlight the importance of studying behavioral risk factors in combination.

The prevalence of atopic disease (AD) in adults has significantly increased in industrialized countries. Psychological traits and lack of skills to cope with stress could be maintaining factors of AD. The first aim of the present study was to compare sense of coherence (SOC), depression, and anger among adult patients with AD, adults with remission from AD, and adults without AD. The second aim was to explore whether depression and anger have significant impacts on SOC. A cross-sectional survey was carried out from May to September of 2007. In total, 43 adult patients with AD, 32 adults with remission from AD, and 63 adults without AD participated. A one-way analysis of variance showed that adult patients with AD have significantly higher levels of depression than adults with remission from AD and adults without AD. Furthermore, structural equation modeling indicated a significant impact of depression on SOC across the three groups, along with a significant impact of anger suppression on depression, particularly in adult patients with AD. The findings of this study suggest that psychological traits have a negative impact on skills for coping with stress, and that this relationship might be a contributory factor for maintenance of AD.

Is importing second-hand products (SHPs) good for Cambodia? To answer this question, one must seriously consider environmental and social effects. The main objective of this study is to identify and assess the economic, social, and environmental impacts of imported SHPs to determine whether or not Cambodia benefits. Imported second-hand computers (SHPCs) and second-hand tires (SHTs) were selected as cases for the study. The study used a scaling checklist to identify significant impacts of these two imported items. Significant impacts were ranked and rated into a single value (score) for integration. Integrated impact assessment showed that imported SHPCs create a verymore » small positive impact (+ 0.1 of + 5) and imported SHTs generate a large negative impact (- 2.83 of - 5). These scores are mainly the result of environmental impact, predominantly waste issues. Thus, current imports of SHPCs and SHTs do not really benefit Cambodia, but instead cause serious environmental problems from their waste issues. The import serves as a channel to transfer waste into developing countries.« less

The socio-economic impact of critical illnesses on patients and their families in Europe has yet to be determined. The aim of this exploratory study was to estimate changes in family circumstances, social and economic stability, care requirements and access to health services for patients during their first 12 months after ICU discharge. Multi-center questionnaire-based study of survivors of critical illness at 6 and 12 months after ICU discharge. Data for 293 consenting patients who spent greater than 48 hours in one of 22 UK ICUs were obtained at 6 and 12 months post-ICU discharge. There was little evidence of a change in accommodation or relationship status between pre-admission and 12 months following discharge from an ICU. A negative impact on family income was reported by 33% of all patients at 6 months and 28% at 12 months. There was nearly a 50% reduction in the number of patients who reported employment as their sole source of income at 12 months (19% to 11%) compared with pre-admission. One quarter of patients reported themselves in need of care assistance at 6 months and 22% at 12 months. The majority of care was provided by family members (80% and 78%, respectively), for half of whom there was a negative impact on employment. Amongst all patients receiving care, 26% reported requiring greater than 50 hours a week. Following discharge, 79% of patients reported attending their primary care physician and 44% had seen a community nurse. Mobility problems nearly doubled between pre-admission and 6 months (32% to 64%). Furthermore, 73% reported moderate or severe pain at 12 months and 44% remained significantly anxious or depressed. Survivors of critical illness in the UK face a negative impact on employment and commonly have a care requirement after discharge from hospital. This has a corresponding negative impact on family income. The majority of the care required is provided by family members. This effect was apparent by 6 months and had not materially improved by 12 months. This exploratory study has identified the potential for a significant socio-economic burden following critical illness.

Effects of Ocean Acidification on Temperate Coastal Marine Ecosystems and Fisheries in the Northeast Pacific

As the oceans absorb anthropogenic CO2 they become more acidic, a problem termed ocean acidification (OA). Since this increase in CO2 is occurring rapidly, OA may have profound implications for marine ecosystems. In the temperate northeast Pacific, fisheries play key economic and cultural roles and provide significant employment, especially in rural areas. In British Columbia (BC), sport (recreational) fishing generates more income than commercial fishing (including the expanding aquaculture industry). Salmon (fished recreationally and farmed) and Pacific Halibut are responsible for the majority of fishery-related income. This region naturally has relatively acidic (low pH) waters due to ocean circulation, and so may be particularly vulnerable to OA. We have analyzed available data to provide a current description of the marine ecosystem, focusing on vertical distributions of commercially harvested groups in BC in the context of local carbon and pH conditions. We then evaluated the potential impact of OA on this temperate marine system using currently available studies. Our results highlight significant knowledge gaps. Above trophic levels 2–3 (where most local fishery-income is generated), little is known about the direct impact of OA, and more importantly about the combined impact of multi-stressors, like temperature, that are also changing as our climate changes. There is evidence that OA may have indirect negative impacts on finfish through changes at lower trophic levels and in habitats. In particular, OA may lead to increased fish-killing algal blooms that can affect the lucrative salmon aquaculture industry. On the other hand, some species of locally farmed shellfish have been well-studied and exhibit significant negative direct impacts associated with OA, especially at the larval stage. We summarize the direct and indirect impacts of OA on all groups of marine organisms in this region and provide conclusions, ordered by immediacy and certainty. PMID:25671596

Objectives. Previous studies showed that negative self-stereotypes detrimentally affect the cognitive performance of marginalized group members; however, these findings were confined to short-term experiments. In the present study, we considered whether stereotypes predicted memory over time, which had not been previously examined. We also considered whether self-relevance increased the influence of stereotypes on memory over time. Method. Multiple waves of memory performance were analyzed using individual growth models. The sample consisted of 395 participants in the Baltimore Longitudinal Study of Aging. Results. Those with more negative age stereotypes demonstrated significantly worse memory performance over 38 years than those with less negative age stereotypes, after adjusting for relevant covariates. The decline in memory performance for those aged 60 and above was 30.2% greater for the more negative age stereotype group than for the less negative age stereotype group. Also, the impact of age stereotypes on memory was significantly greater among those for whom the age stereotypes were self-relevant. Discussion. This study shows that the adverse influence of negative self-stereotypes on cognitive performance is not limited to a short-term laboratory effect. Rather, the findings demonstrate, for the first time, that stereotypes also predict memory performance over an extended period in the community. PMID:22056832

Different patterns of puberty effect in neural oscillation to negative stimuli: sex differences.

2014-12-01

The present study investigated the impact of puberty on sex differences in neural sensitivity to negative stimuli. Event-related oscillation technique was used. Because girls are more vulnerable to affective disturbances than boys during adolescence, it was hypothesized that puberty exerts different influences on neural sensitivity to negative stimuli in boys and girls. EEGs were recorded for highly negative (HN), mildly negative (MN) and neutral pictures, when boys and girls distinct in pubertal status performed a non-emotional distracting task. No emotion effect and its interaction with sex and puberty were observed in response latencies. However, puberty influenced the gamma-band oscillation effect for negative stimuli differently for boys and girls: Pre-pubertal boys showed a significant emotion effect for HN stimuli, whose size was decreased in pubertal boys. By contrast, there was a significant emotion effect for HN stimuli in pubertal girls but not in pre-pubertal girls. On the other hand, the size of the emotion effect for HN stimuli was similar for pre-pubertal boys and girls; while this effect was significantly more pronounced in pubertal girls compared to pubertal boys. Additionally, the size of the emotion effect in gamma oscillations decreased as a function of pubertal development during both HN and MN stimulation in boys. For girls, the emotion effect in gamma oscillations increased with pubertal development during HN stimulation. Thus, puberty is associated with reduced neural sensitivity in boys but increased sensitivity in girls, in reaction to negative stimuli. The implications of these results for the psychopathology during adolescence were discussed.

Duration of active psychosis and first-episode psychosis negative symptoms.

2017-02-01

Duration of untreated psychosis (DUP) has been associated with negative symptoms in several studies; however, longitudinal findings have been inconsistent. No previous study has accounted for active psychosis after presentation, although this could impact on outcomes in a manner similar to DUP. We measured Scale for the Assessment of Positive Symptoms at frequent intervals during the 12 months after initial presentation to determine the active psychosis duration for 230 individuals with first-episode psychosis. This duration was added to DUP prior to presentation to create a new variable, duration of active psychosis (DAP). Negative symptoms were divided into expressivity and motivation/pleasure domains as measured by Scale for the Assessment of Negative Symptoms (SANS). The relationship of DUP and DAP with negative symptoms at 24-month follow up was determined and confounders controlled for using regression analysis. When DUP and DAP were compared as binary variables with long and short groups, 25.2% of individuals had differing category membership. DAP had a significant uncorrected association with both expressivity domain and motivation/pleasure domains at 24 months; however, relationship with DUP was not significant. DAP remained a significant predictor of 24-month expressivity domain after controlling for potential confounders. Active psychosis after presentation is substantial, which is a limitation of DUP studies if active psychosis is considered as the key factor within DUP. DAP is a better predictor of negative symptoms than DUP at 2-year follow up, which suggests this concept requires further research. © 2015 Wiley Publishing Asia Pty Ltd.

Vitiligo is a disorder of the melanocytes that results in a dynamic spectrum of skin depigmentation. Its etiology is complex and multifactorial, with data supporting several different hypotheses. Given its prominent phenotype, vitiligo has a significant negative impact on quality of life. Coupled with the chronic and incurable nature of the disease, this presents a formidable treatment challenge. Several treatment modalities have been instituted over the years, with varying efficacy. This chapter focuses on the use of ultraviolet light in vitiligo as an established therapeutic option.

Therapists who work with trauma clients are impacted both positively and negatively. However, most studies have tended to focus on the negative impact of the work, the quantitative evidence has been inconsistent, and the research has primarily been conducted outside the United Kingdom. This study aimed to assess the prevalence of, and identify predictor variables for, compassion satisfaction, burnout, and secondary traumatic stress in a group of UK therapists (N=253) working with adult trauma clients. An online questionnaire was developed which used The Professional Quality of Life Scale (Version 5) to assess compassion satisfaction, burnout, and secondary traumatic stress and collect demographics and other pertinent information. Whilst the majority of therapists scored within the average range for compassion satisfaction and burnout, 70% of scores indicated that therapists were at high risk of secondary traumatic stress. Maturity, time spent engaging in research and development activities, a higher perceived supportiveness of management, and supervision predicted higher potential for compassion satisfaction. Youth and a lower perceived supportiveness of management predicted higher risk of burnout. A higher risk of secondary traumatic stress was predicted in therapists engaging in more individual supervision and self-care activities, as well as those who had a personal trauma history. UK therapists working with trauma clients are at high risk of being negatively impacted by their work, obtaining scores which suggest a risk of developing secondary traumatic stress. Of particular note was that exposure to trauma stories did not significantly predict secondary traumatic stress scores as suggested by theory. However, the negative impact of working with trauma clients was balanced by the potential for a positive outcome from trauma work as a majority indicated an average potential for compassion satisfaction.

Non-disclosure criminal prosecutions among gay, bisexual and other men who have sex with men (MSM) are increasing, even though transmission risk is low when effective antiretroviral treatment (ART) is used. Reduced HIV testing may reduce the impact of HIV "test and treat" strategies. We aimed to quantify the potential impact of non-disclosure prosecutions on HIV testing and transmission among MSM. MSM attending an HIV and primary care clinic in Toronto completed an audio computer-assisted self-interview questionnaire. HIV-negative participants were asked concern over non-disclosure prosecution altered their likelihood of HIV testing. Responses were characterized using cross-tabulations and bivariate logistic regressions. Flow charts modelled how changes in HIV testing behaviour impacted HIV transmission rates controlling for ART use, condom use and HIV status disclosure. 150 HIV-negative MSM were recruited September 2010 to June 2012. 7% (9/124) were less or much less likely to be tested for HIV due to concern over future prosecution. Bivariate regression showed no obvious socio/sexual demographic characteristics associated with decreased willingness of HIV testing to due concern about prosecution. Subsequent models estimated that this 7% reduction in testing could cause an 18.5% increase in community HIV transmission, 73% of which was driven by the failure of HIV-positive but undiagnosed MSM to access care and reduce HIV transmission risk by using ART. Fear of prosecution over HIV non-disclosure was reported to reduce HIV testing willingness by a minority of HIV-negative MSM in Toronto; however, this reduction has the potential to significantly increase HIV transmission at the community level which has important public health implications.

Objectives: Existing treatments for schizophrenia can improve positive symptoms, but it is unclear if they have any impact on negative symptoms. This meta-analysis was conducted to assess the efficacy of available treatments for negative symptoms in schizophrenia. Methods: All randomized-controlled trials of interventions for negative symptoms in schizophrenia until December 2013 were retrieved; 168 unique and independent placebo-controlled trials were used. Negative symptom scores at baseline and follow-up, duration of illness, doses of medication, type of interventions, and sample demographics were extracted. Heterogeneity was addressed with the I 2 and Q statistic. Standardized mean difference in values of the Negative Symptom Rating Scale used in each study was calculated as the main outcome measure. Results: 6503 patients in the treatment arm and 5815 patients in the placebo arm were included. No evidence of publication biases found. Most treatments reduced negative symptoms at follow-up relative to placebo: second-generation antipsychotics: −0.579 (−0.755 to −0.404); antidepressants: −0.349 (−0.551 to −0.146); combinations of pharmacological agents: −0.518 (−0.757 to −0.279); glutamatergic medications: −0.289 (−0.478 to −0.1); psychological interventions: −0.396 (−0.563 to −0.229). No significant effect was found for first-generation antipsychotics: −0.531 (−1.104 to 0.041) and brain stimulation: −0.228 (−0.775 to 0.319). Effects of most treatments were not clinically meaningful as measured on Clinical Global Impression Severity Scale. Conclusions and Relevance: Although some statistically significant effects on negative symptoms were evident, none reached the threshold for clinically significant improvement. PMID:25528757

The health and well-being benefits of access to green space are well documented. Research suggests positive findings regardless of social group, however barriers exist that limit access to green space, including proximity, geography and differing social conditions. Current public health policy aims to broaden the range of environmental public health interventions through effective partnership working, providing opportunities to work across agencies to promote the use of green space. Health Impact Assessment (HIA) is a combination of methods and procedures to assess the potential health and well-being impacts of policies, developments and projects. It provides a means by which negative impacts can be mitigated and positive impacts can be enhanced, and has potential application for assessing green space use. This paper describes the application of a HIA approach to a multi-agency project (Stepping Stones to Nature--SS2N) in the UK designed to improve local green spaces and facilitate green space use in areas classified as having high levels of deprivation. The findings suggest that the SS2N project had the potential to provide significant positive benefits in the areas of physical activity, mental and social well-being. Specific findings for one locality identified a range of actions that could be taken to enhance benefits, and mitigate negative factors such as anti-social behaviour. The HIA approach proved to be a valuable process through which impacts of a community development/public health project could be enhanced and negative impacts prevented at an early stage; it illustrates how a HIA approach could enhance multi-agency working to promote health and well-being in communities.

More than looking good: impact on quality of life moderates the relationship between functional body image and physical activity in men with SCI.

Cross-sectional. To examine the relationship between body image and leisure time physical activity (LTPA) among men with spinal cord injury (SCI). Specifically, to examine the moderating function of the perceived impact of body image on quality of life (QOL). Ontario, Canada. Men with SCI (N=50, 50% paraplegic) reported, (a) their functional and appearance body image (Adult Body Satisfaction Questionnaire), (b) their perceived impact of body image on QOL and (c) LTPA performed over the previous 3 days. Body image was in the 'normal' range compared with the general population. Linear regression analysis found a significant LTPA x body image impact on QOL interaction beta=0.39, P<0.05. Post hoc analysis showed that among individuals who reported a negative effect of body image on QOL, those who engaged in LTPA were less satisfied with their physical function than those who did not. For those who did not perceive their body image to negatively impact their QOL, there was generally no difference in functional body image between those who engaged in LTPA and those who did not. Appearance body image is not related to LTPA for men with SCI. It has been suggested that body dissatisfaction may motivate some individuals to engage in LTPA. However, for men living with SCI, functional body image may be associated with LTPA only when a negative effect on QOL is perceived. Future research should consider the moderating function of the perceived impact of body image on QOL when examining the relationship between LTPA and body image among men living with SCI.

Attention deficit hyperactivity disorder (ADHD) is a prevalent developmental disorder that seriously and negatively impacts a child's health-related quality of life (HRQOL). However, no meta-analysis has been conducted to examine the magnitude of impact, domains affected and factors moderating the impact. This review included nine studies that compared HRQOL of children or adolescents with ADHD with those with typical development using both child self-reports and parent proxy-reports. Seven among nine studies were meta-analytically synthesized to examine the degree of impact of ADHD on children and adolescents, parent-child discrepancy, and the moderators. The results indicate that ADHD impact a child's or adolescent's HRQOL negatively with a moderate effect in physical and a severe effect in psychosocial (i.e., emotional, social, and school) domains. Parental ratings of overall HRQOL in children or adolescents with ADHD were not significantly different from child's ratings when compared with typically developing children and adolescents. Age was negatively associated with all domains of HRQOL in children and adolescents with ADHD both by parent- and child-ratings, and the strongest effect was found in parental ratings of child's emotional HRQOL, with a moderate correlation. This meta-analysis suggests that HRQOL may be assessed in children and adolescents with ADHD both by parent proxy- and child self-reports, and that interventions may be planned accordingly. Future meta-analysis may explore how measures of HRQOL and other factors including child, parental, familiar and school characteristics influence the impact of ADHD and the parent-child agreement in children and adolescents.

Early therapeutic decision-making is crucial in patients with higher-risk MDS. We evaluated the impact of clinical parameters and mutational profiles in 134 consecutive patients treated with azacitidine using a combined cohort from Karolinska University Hospital (n=89) and from King's College Hospital, London (n=45). While neither clinical parameters nor mutations had a significant impact on response rate, both karyotype and mutational profile were strongly associated with survival from the start of treatment. IPSS high-risk cytogenetics negatively impacted overall survival (median 20 vs 10 months; p<0.001), whereas mutations in histone modulators (ASXL1, EZH2) were associated with prolonged survival (22 vs 12 months, p=0.01). This positive association was present in both cohorts and remained highly significant in the multivariate cox model. Importantly, patients with mutations in histone modulators lacking high-risk cytogenetics showed a survival of 29 months compared to only 10 months in patients with the opposite pattern. While TP53 was negatively associated with survival, neither RUNX1-mutations nor the number of mutations appeared to influence survival in this cohort. We propose a model combining histone modulator mutational screening with cytogenetics in the clinical decision-making process for higher-risk MDS patients eligible for treatment with azacitidine.

The effects of antithrombotic drugs on random and free flap survival have been investigated in the past, but the experimental and clinical results are not in agreement. A perforator-based critical ischaemia model was used to evaluate the effects of different perioperatively administered pharmaceutical agents on tissue ischaemia and to assess the potential additional haemorheological or vasodilative effects of antithrombotics on flap microcirculation. Combined laser Doppler flowmetry and remission spectroscopy revealed an increase in certain microcirculation parameters in most groups in comparison with saline controls, and these changes correlated with flap survival. Clopidogrel and hirudin significantly improved the amount of viable flap tissue in comparison with controls, while unfractioned heparin had a negative effect on flap survival. Low molecular weight heparin, aspirin, pentoxifylline, and hydroxyethyl starch had no impact on the amount of viable flap tissue. A higher complication rate was observed in all experimental groups, but only clopidogrel had a negative impact on the flap viability. Our results add to the body of evidence supporting the conclusion that perioperative antithrombotic treatment improves flap survival. Clopidogrel and hirudin are effective pharmacological agents that significantly increased the viability of perforator-based skin flaps in rats, but at a higher risk of postoperative bleeding.

A possible connection between thermal comfort and health

Stoops, John L.

It is a well-established fact that cardiovascular health requires periodic exercise during which the human body often experiences significant physical discomfort. It is not obvious to the exerciser that the short-term pain and discomfort has a long-term positive health impact. Many cultures have well-established practices that involve exposing the body to periodic thermal discomfort. Scandinavian saunas and American Indian sweat lodges are two examples. Both are believed to promote health and well-being. Vacations often intentionally include significant thermal discomfort as part of the experience (e.g., sunbathing, and downhill skiing). So people often intentionally make themselves thermally uncomfortable yet the entiremore » foundation of providing the thermal environment in our buildings is done to minimize the percentage of people thermally dissatisfied. We must provide an environment that does not negatively impact short-term health and we need to consider productivity but are our current thermal comfort standards too narrowly defined and do these standards actually contribute to longer-term negative health impacts? This paper examines the possibility that the human body thermoregulatory system has a corollary relationship to the cardiovascular system. It explores the possibility that we have an inherent need to exercise our thermoregulatory system. Potential, physiological, sociological and energy ramifications of these possibilities are discussed.« less

Response of a tropical tree to non-timber forest products harvest and reduction in habitat size

Non-timber forest products (NTFPs) are widely harvested by local people for their livelihood. Harvest often takes place in human disturbed ecosystems. However, our understanding of NTFPs harvesting impacts in fragmented habitats is limited. We assessed the impacts of fruit harvest, and reduction in habitat size on the population structures of Pentadesma butyracea Sabine (Clusiaceae) across two contrasting ecological regions (dry vs. moist) in Benin. In each region, we selected three populations for each of the three fruit harvesting intensities (low, medium and high). Harvesting intensities were estimated as the proportion of fruits harvested per population. Pentadesma butyracea is found in gallery forests along rivers and streams. We used the width of gallery forests as a measure of habitat size. We found negative effects of fruit harvest on seedling and adult density but no significant effect on population size class distribution in both ecological regions. The lack of significant effect of fruit harvest on population structure may be explained by the ability of P. butyracea to compensate for the negative effect of fruit harvesting by increasing clonal reproduction. Our results suggest that using tree density and population structure to assess the ecological impacts of harvesting clonal plants should be done with caution. PMID:28850624

Emotional stimuli generally command more brain processing resources than non-emotional stimuli, but the magnitude of this effect is subject to voluntary control. Cognitive reappraisal represents one type of emotion regulation that can be voluntarily employed to modulate responses to emotional stimuli. Here, the late positive potential (LPP), a specific event-related brain potential (ERP) component, was measured in response to neutral, positive and negative images while participants performed an evaluative categorization task. One experimental group adopted a "negative frame" in which images were categorized as negative or not. The other adopted a "positive frame" in which the exact same images were categorized as positive or not. Behavioral performance confirmed compliance with random group assignment, and peak LPP amplitude to negative images was affected by group membership: brain responses to negative images were significantly reduced in the "positive frame" group. This suggests that adopting a more positive appraisal frame can modulate brain activity elicited by negative stimuli in the environment.

Background Negative symptoms of schizophrenia have a severe impact on functional outcomes and treatment options are limited. Arts therapies are currently recommended but more evidence is required. Aims To assess body psychotherapy as a treatment for negative symptoms compared with an active control (trial registration: ISRCTN84216587). Method Schizophrenia out-patients were randomised into a 20-session body psychotherapy or Pilates group. The primary outcome was negative symptoms at end of treatment. Secondary outcomes included psychopathology, functional, social and treatment satisfaction outcomes at treatment end and 6-months later. Results In total, 275 participants were randomised. The adjusted difference in negative symptoms was 0.03 (95% CI −1.11 to 1.17), indicating no benefit from body psychotherapy. Small improvements in expressive deficits and movement disorder symptoms were detected in favour of body psychotherapy. No other outcomes were significantly different. Conclusions Body psychotherapy does not have a clinically relevant beneficial effect in the treatment of patients with negative symptoms of schizophrenia. PMID:27151073

Introduction: We tested the hypothesis that REM sleep contributes to core features of cognitive dysfunction of anxious depression including negative self-appraisals, biased memory processing and unpleasant dream content. Methods: After a habituation night in a sleep lab, a convenience sample of 35 healthy college students and 20 depressed/anxious students were awakened 10 minutes into a REM sleep episode and then 10 minutes into a NREM sleep episode. Awakenings were counterbalanced to control circadian effects. After each awakening participants reported a dream and then completed memory recall, mood and self-appraisal tasks. Results: Self-appraisals of depressed/anxious participants were significantly less positive and significantly more negative after awakenings from REM sleep vs NREM sleep. Appraisal of the REM sleep dream self was negative for depressed/anxious subjects only. Recall of negative memories was significantly more frequent after REM vs NREM sleep awakenings for both depress/anxious and healthy participants. REM sleep dreams were associated with greater frequencies of negative emotion, greater aggression and victimization rates than dreams in NREM sleep for depressed/anxious participants. Limitations: Depressed/anxious participants were classified as such on the basis of mood scales rather than clinical interview. All participants were drawn from a volunteer college student population and thus our results may not be applicable to some elderly clinical populations. Conclusions: REM appears to facilitate cognitive distortions of anxious depression. PMID:19631989

Background. Icodextrin is a glucose polymer derived by hydrolysis of cornstarch. The different biocompatibility profile of icodextrin-containing peritoneal dialysis (PD) solutions may have a positive influence on peritoneal host defence. Furthermore, cases of sterile peritonitis potentially associated with icodextrin have been reported. Methods. The primary objective of this multicentre, longitudinal, observational, non-interventional, prospective cohort study, which included 722 PD patients, was to evaluate the incidence of overall peritonitis in patients treated with icodextrin-containing PD solutions (Extraneal™) used during one long-dwell exchange/day compared with those treated with non-icodextrin-containing PD solutions. The secondary objective was to determine if culture-negative peritonitis rates differed between patients treated with icodextrin from two independent manufacturers. All peritonitis episodes were assessed by a Steering Committee in a blind manner. Results. There was no significant difference between icodextrin-treated and control patients in the adjusted overall, culture-positive or culture-negative peritonitis rates. When stratified by the icodextrin supplier, there was no significant difference in the adjusted rate of culture-negative peritonitis episodes between groups. Conclusion. Subjects receiving icodextrin as part of their PD regimen experienced neither a higher rate of culture-negative peritonitis nor a lower rate of infectious peritonitis compared with non-icodextrin users. There was no significant influence of the icodextrin raw material supplier on peritonitis rates. PMID:18556747

Impact of the FTSE4Good Index on firm price: an event study.

Martin Curran, M; Moran, Dominic

2007-03-01

This paper examines whether corporate financial performance is affected by public endorsement of environmental and social performance. Event study methodology, which relies on the notion of market efficiency, is used to examine the relationship between positive and negative announcements and changes in share prices or daily returns. Inclusion in and deletion from the FTSE4Good UK Index is used as a proxy measure for good (poor) corporate social responsibility. The abnormal or unexpected daily returns associated with an event are calculated and their significance tested. The results show a trend towards positive and negative announcements having the expected effects on daily returns. But these movements are not significant and the data do not suggest that a firm's presence on the index brings it any significant financial return for signalling its corporate social responsibility.

Relations between benthic community structure and metals concentrations in aquatic macroinvertebrates: Clark Fork River, Montana

USGS Publications Warehouse

1995-01-01

We sampled macroinvertebrate communities at six sites on the upper Clark Fork River, Montana, to determine relations between macroinvertebrate community structure and metals in invertebrates and the best benthic community metrics to use for ranking sites based on the relative severity of the effects of metals. Concentrations (μg/g) of six metals in invertebrates were determined: Al (range = 591–4193), As (2.7–34.1), Cd (0.13–8.38), Cu (26–1382), Pb (0.54–67.1), and Zn (212–1665). Concentrations of As, Cd, Cu, Pb, and total metals were significantly correlated with at least one benthic metric. Copper (r = 0.88–0.94) and total metals (r = 0.90–0.97) provided the most highly significant correlations. Based on longitudinal site comparisons of metals in invertebrates, benthic community structure, and differences between proportionally scaled ranks, five benthic metrics provided the best indicators of relative impact: taxa richness, Ephemeroptera-Plecoptera-Trichoptera (EPT) richness, chironomid richness, percentage of the most dominant taxon, and density. The two sites with the highest accumulations of invertebrate metals also demonstrated the greatest relative degree of impact based on these parameters. The most meaningful combinations of metrics indicate that the benthic community at the most upstream site is being severely impacted by metals. Two sites demonstrated little or no negative impact, and three sites demonstrated low or moderate levels of negative impacts, which may be due to a combination of metals and other factors such as organic enrichment. We recommend that benthic community structure and metals in invertebrates collected from riffle habitats be used to determine relative impacts in metals-contaminated river systems, owing to their close relation to metal availability and transfer to higher trophic levels.

Background: The association between the CpG island methylator phenotype (CIMP) and clinical outcomes in metastatic colorectal cancer remains unclear. We investigated the prognostic impact of CIMP in patients with metastatic colorectal cancer treated with systemic chemotherapy. Methods: Eight CIMP-specific promoters (CACNA1G, IGF2, NEUROG1, RUNX3, SOCS1, CDKN2A, CRABP1, and MLH1) were examined. The CIMP status was determined by the number of methylated promoters as high (⩾5), low (1–4), and negative (0). Results: A total of 153 patients were included (men/women, 103/50; median age, 61 years; range, 22–80 years). The CIMP status was negative/low/high in 77/ 69/7 patients, respectively. Overall survival (OS) was significantly different among the three CIMP groups, with median values of 35.7, 22.2, and 9.77 months for the negative, low, and high groups, respectively (P<0.001). For patients treated with fluoropyrimidine and oxaliplatin first-line chemotherapy (N=128), OS and progression-free survival (PFS) were significantly different among the three CIMP groups; the median OS was 37.9, 23.8, and 6.77 months for the negative, low, and high groups, respectively (P<0.001), while the median PFS was 9.97, 7.87, and 1.83 months, respectively (P=0.002). Response rates were marginally different among the three CIMP groups (53.4% vs 45.1% vs 16.7%, respectively; P=0.107). For patients treated with fluoropyrimidine and irinotecan second-line chemotherapy (N=86), only OS showed a difference according to the CIMP status, with median values of 20.4, 13.4, and 2.90 months for the negative, low, and high groups, respectively (P<0.001). Conclusions: The CIMP status is a negative prognostic factor for patients with metastatic colorectal cancer treated with chemotherapy. PMID:27310704

The association between the CpG island methylator phenotype (CIMP) and clinical outcomes in metastatic colorectal cancer remains unclear. We investigated the prognostic impact of CIMP in patients with metastatic colorectal cancer treated with systemic chemotherapy. Eight CIMP-specific promoters (CACNA1G, IGF2, NEUROG1, RUNX3, SOCS1, CDKN2A, CRABP1, and MLH1) were examined. The CIMP status was determined by the number of methylated promoters as high (⩾5), low (1-4), and negative (0). A total of 153 patients were included (men/women, 103/50; median age, 61 years; range, 22-80 years). The CIMP status was negative/low/high in 77/ 69/7 patients, respectively. Overall survival (OS) was significantly different among the three CIMP groups, with median values of 35.7, 22.2, and 9.77 months for the negative, low, and high groups, respectively (P<0.001).

Background: The impact of first episode psychosis (FEP) upon parents’ experience of caregiving has been well-documented. However, the determinants and nature of this remain poorly understood in siblings. It is hypothesized that siblings of young people with FEP are also impacted by caregiving and burden. This study aimed to characterize the experience of caregiving for siblings of young people with FEP. Method: Survey methodology was used to explore the experience of 157 siblings in the first 18 months of their brother or sister’s treatment for FEP. Participants reported on their appraisal of the negative and positive aspects of caregiving as measured by the Experience of Caregiving Inventory (ECI). Descriptive statistics were used to establish the results for the total sample as well as for gender and birth order differences. A series of multivariate regression analyses were conducted to determine the relationships between illness characteristics and siblings’ experience of caregiving. Results: Older brothers reported the lowest scores for negative experiences in caregiving and younger sisters reported the highest. Negative experiences in caregiving resulted in less warmth within the sibling relationship and impacted negatively upon quality of life. When the young person with FEP had attempted suicide and/or been physically violent, siblings experienced more caregiver burden. Multivariate analysis showed that female gender was a significant factor in explaining the impact of illness related variables on the experience of caregiving. Conclusion: Suicide attempts and a history of violence resulted in higher caregiving burden for siblings regardless of whether they lived with the young person experiencing FEP or not. Female siblings are at higher risk of negative experiences from caregiving resulting in a reduced quality of life and a changed sibling relationship. Suicide attempts and violence are indicators for intensive case management to improve outcomes for the individual with FEP which may in turn reduce the burden experienced by the sibling. Clinicians can use these findings to identify siblings, assertively intervene and provide increased psychological support, psychoeducation and practical problem solving to reduce the burden. The caregiving role that they already play for their ill brother or sister should be recognized. PMID:28588522

Cordiner, M. A.; Charnley, S. B.

2012-01-01

The presence of negative ions (anions) in cometary comae is known from Giotto mass spectrometry of IP/Halley. The anions O(-), OH(-), C(-), CH(-) and CN(-) have been detected, as well as unidentified anions with masses 22-65 and 85-110 amu [I]. Organic molecular anions such as C4H(-) and C6H(-) are known to have a significant impact on the charge balance of interstellar clouds and circumstellar envelopes and have been shown to act as catalysts for the gas phase synthesis of larger hydrocarbon molecules in the ISM, but their importance in cometary comae has not yet been fully explored. We present details of our new models for the chemistry of cometary comae that include atomic and molecular anions. We calculate the impact of these anions on the charge balance and examine their importance for cometary coma chemistry.

2012-01-01

Objective Negative inferential style and deficits in emotional clarity have been identified as vulnerability factors for depression in adolescence, particularly when individuals experience high levels of life stress. However, previous research has not integrated these characteristics when evaluating vulnerability to depression. Method In the present study, a racially-diverse community sample of 256 early adolescents (ages 12 and 13) completed a baseline visit and a follow-up visit nine months later. Inferential style, emotional clarity, and depressive symptoms were assessed at baseline, and intervening life events and depressive symptoms were assessed at follow-up. Results Hierarchical linear regressions indicated that there was a significant three-way interaction between adolescents’ weakest-link negative inferential style, emotional clarity, and intervening life stress predicting depressive symptoms at follow-up, controlling for initial depressive symptoms. Adolescents with low emotional clarity and high negative inferential styles experienced the greatest increases in depressive symptoms following life stress. Emotional clarity buffered against the impact of life stress on depressive symptoms among adolescents with negative inferential styles. Similarly, negative inferential styles exacerbated the impact of life stress on depressive symptoms among adolescents with low emotional clarity. Conclusions These results provide evidence of the utility of integrating inferential style and emotional clarity as constructs of vulnerability in combination with life stress in the identification of adolescents at risk for depression. They also suggest the enhancement of emotional clarity as a potential intervention technique to protect against the effects of negative inferential styles and life stress on depression in early adolescence.

Environmental stress, oxytocin receptor gene (OXTR) polymorphism, and mental health following collective stress.

PubMed

Lucas-Thompson, Rachel G; Holman, E Alison

2013-04-01

We examined whether the oxytocin receptor gene (OXTR) single nucleotide polymorphism (SNP) rs53576 genotype buffers the combined impact of negative social environments (e.g., interpersonal conflict/constraint) and economic stress on post-traumatic stress (PTS) symptoms and impaired daily functioning following collective stress (September 11th terrorist attacks). Saliva was collected by mail and used to genotype 704 respondents. Participants completed Web-based assessments of pre-9/11 mental health, acute stress 9-23 days after 9/11, the quality of social environments 1 year post-9/11, economic stress 18 months post-9/11, and PTS symptoms and impaired functioning 2 and 3 years post-9/11. Interactions between negative social environments and economic stress were examined separately based on OXTR rs53576 genotype (GG vs. any A allele). For individuals with an A allele, a negative social environment significantly increased PTS symptoms without regard to the level of economic stress experienced. However, for respondents with a GG genotype, negative social environments predicted elevated PTS symptoms only for those also experiencing high economic stress. Gender moderated associations between negative social environments, economic stress, and impaired functioning. The functioning of females was most affected by negative social environments regardless of genotype and economic stress, whereas the functioning of males was differentially susceptible to economic stress depending on OXTR genotype and negative social environments. These findings suggest that it is important to consider the combined impact of gender and ongoing stress in different domains as moderators of genetic vulnerability following collective stress.

Perceived Discrimination and Health: A Meta-Analytic Review

PubMed Central

Pascoe, Elizabeth A.; Richman, Laura Smart

2009-01-01

Perceived discrimination has been studied with regard to its impact on several types of health effects. This meta-analysis provides a comprehensive account of the relationships between multiple forms of perceived discrimination and both mental and physical health outcomes. In addition, this meta-analysis examines potential mechanisms by which perceiving discrimination may affect health, including through psychological and physiological stress responses and health behaviors. Analysis of 134 samples suggests that when weighting each study’s contribution by sample size, perceived discrimination has a significant negative effect on both mental and physical health. Perceived discrimination also produces significantly heightened stress responses and is related to participation in unhealthy and nonparticipation in healthy behaviors. These findings suggest potential pathways linking perceived discrimination to negative health outcomes. PMID:19586161

Recent research has suggested significant negative effects of the Global Financial Crisis (GFC) on mental health and wellbeing. In this article, the authors suggest that the developmental period of late adolescence may be at particular risk of economic downturns. Harmonizing 4 longitudinal cohorts of Australian youth (N = 38,017), we estimate the impact of the GFC on 1 general and 11 domain specific measures of wellbeing at age 19 and 22. Significant differences in wellbeing in most life domains were found, suggesting that wellbeing is susceptible to economic shocks. Given that the GFC in Australia was relatively mild, the finding of clear negative effects across 2 ages is of international concern. (c) 2016 APA, all rights reserved).

The objective of this population-based cross-sectional study was to estimate rural-urban disparity in the oral health-related quality of life (OHRQoL) of the Quebec adult population. A 2-stage sampling design was used to collect data from the 1788 parents/caregivers of schoolchildren living in the 8 regions of the province of Quebec in Canada. Andersen's behavioural model for health services utilization was used as a conceptual framework. Place of residency was defined according to the Statistics Canada Census Metropolitan Area and Census Agglomeration Influenced Zone classification. The outcome of interest was OHRQoL measured using the Oral Health Impact Profile (OHIP)-14 validated questionnaire. Data weighting was applied, and the prevalence, extent and severity of negative oral health impacts were calculated. Statistical analyses included descriptive statistics, bivariate analyses and binary logistic regression. The prevalence of poor oral health-related quality life (OHRQoL) was statistically higher in rural areas than in urban zones (P = .02). Rural residents reported a significantly higher prevalence of negative daily-life impacts in pain, psychological discomfort and social disability OHIP domains (P < .05). Additionally, the rural population showed a greater number of negative oral health impacts (P = .03). There was no significant rural-urban difference in the severity of poor oral health. Logistic regression indicated that the prevalence of poor OHRQoL was significantly related to place of residency (OR = 1.6; 95% CI = 1.1-2.5; P = .022), perceived oral health (OR = 9.4; 95% CI = 5.7-15.5; P < .001), dental treatment needs factors (perceived need for dental treatment, pain, dental care seeking) (OR = 8.7; 95% CI = 4.8-15.6; P < .001) and education (OR = 2.7; 95% CI = 1.8-3.9; P < .001). The results of this study suggest a potential difference in OHRQoL of Quebec rural and urban populations, and a need to develop strategies to promote oral health outcomes, specifically for rural residents. Further studies are needed to confirm these results. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Acute otitis media (AOM) affects both child and parental quality of life (QoL). Data on QoL associated with AOM in Malaysia is sparse, and the burden of indirect costs have not been previously reported. To determine the effect of pediatric AOM on child and parental QoL in Malaysia and its economic impact (indirect costs). We utilized a set of QoL questionnaires (PAR-AOM-QOL, OM-6, and EQ-5D) combined with questions addressing work/productivity loss and financial costs associated with caring for a child during his or her illness in an observational, multicenter, prospective study. One hundred and ten AOM patients aged ≤5 years were included in the analysis. The majority of respondents were the patient's mother. Parental QoL was negatively affected for both emotional and daily disturbance scales, but the level of disturbance was low. Using OM-6, the greatest negative impact was on the child's QoL, followed by caregiver concerns, physical suffering, and emotional distress. Using EQ-5D, a moderately positive relationship between parents' emotional disturbance and daily disturbance, and a weak, negative correlation between parental emotional disturbance and parental health status was found. Parents with paid employment took an average of 21 h from work to care for their child, at an average cost of 321.8 Malaysian ringgit (US$97) in addition to their contribution to direct medical costs. Productivity losses whilst at work, uncompensated wage losses, and leisure time losses are also reported. This study found that AOM is associated with some negative impact on parental QoL and significant economic impact at both patient and societal levels. The findings provide useful data on healthcare resource utilization and disease burden of AOM in Malaysia.

PubMed

Davis, Seth; Ferrar, Saskia; Sadikaj, Gentiana; Binik, Yitzchak; Carrier, Serge

2017-04-03

Peyronie's disease (PD) has a negative impact on men's sexual functioning and quality of life, but little is known about why some men cope better than others and what the effects of PD are on their relationships. The aims of the present study were to describe negative affect, pain, and relationship and sexual satisfaction in men with PD, and to explore their psychosocial correlates. Participants were 110 men diagnosed with PD. All men completed questionnaires. The main outcome measures were as follows: Global Measure of Sexual Satisfaction, Dyadic Adjustment Scale, McGill Pain Questionnaire, and Negative Affect Scale. The predictor variables were the following: Experience of Shame Scale, Body Esteem Scale, Body Image Self-Consciousness Scale, Index of Male Genital Image, a modified Pain Catastrophizing Scale, and a modified Multidimensional Pain Inventory. Although men with PD had mean sexual/relationship satisfaction and negative affect scores indicating mild impairment, there was a wide range of variation, with 42% to 52% scoring in the clinical range. Catastrophizing was significantly associated with reduced sexual satisfaction and increased negative affect and pain. Shame was also associated with increased negative affect. The significant associations of relationship satisfaction were partner responses and shame. Given the lack of curative treatment in PD, understanding why some men cope better than others may guide therapy. Shame, catastrophizing, and partner responses may be important therapeutic targets.

Indirect effect of financial strain on daily cortisol output through daily negative to positive affect index in the Coronary Artery Risk Development in Young Adults Study.

PubMed

Puterman, Eli; Haritatos, Jana; Adler, Nancy E; Sidney, Steve; Schwartz, Joseph E; Epel, Elissa S

2013-12-01

Daily affect is important to health and has been linked to cortisol. The combination of high negative affect and low positive affect may have a bigger impact on increasing HPA axis activity than either positive or negative affect alone. Financial strain may both dampen positive affect as well as increase negative affect, and thus provides an excellent context for understanding the associations between daily affect and cortisol. Using random effects mixed modeling with maximum likelihood estimation, we examined the relationship between self-reported financial strain and estimated mean daily cortisol level (latent cortisol variable), based on six salivary cortisol assessments throughout the day, and whether this relationship was mediated by greater daily negative to positive affect index measured concurrently in a sample of 776 Coronary Artery Risk Development in Young Adults (CARDIA) Study participants. The analysis revealed that while no total direct effect existed for financial strain on cortisol, there was a significant indirect effect of high negative affect to low positive affect, linking financial strain to elevated cortisol. In this sample, the effects of financial strain on cortisol through either positive affect or negative affect alone were not significant. A combined affect index may be a more sensitive and powerful measure than either negative or positive affect alone, tapping the burden of chronic financial strain, and its effects on biology.

Effects of induced rumination on body dissatisfaction: Is there any difference between men and women?

PubMed

Rivière, Julie; Rousseau, Amélie; Douilliez, Céline

2018-05-19

Rumination is a factor in the development and maintenance of body dissatisfaction. However, no study has yet investigated the impact of the type of rumination on body image. The first aim of this study was to examine whether the induction of analytic-abstract vs. concrete-experiential rumination affects body dissatisfaction following an induction of negative body image. The second objective was to examine gender differences in these effects. Following induction of negative body image, 102 university undergraduates were randomly assigned to one of three experimental conditions-distraction, concrete rumination or abstract rumination. As expected, there were significant main effects of gender and condition, and a significant interaction between gender and condition on change in body dissatisfaction. In women abstract rumination predicted the highest increase in body dissatisfaction, whereas concrete rumination predicted the highest increase in body dissatisfaction in men. Given that our sample consisted of undergraduate students, our findings cannot be generalized to clinical sample suffering from eating disorder. The different types of rumination seem to impact differentially body dissatisfaction in men and women. Copyright © 2018 Elsevier Ltd. All rights reserved.

The accumulation of plant pigments in mung bean ( Vigna radiata L.) seedlings was measured after clinorotation (2 rpm for 2-4 days), and compared to a stationary control. The pigments measured included chlorophyll and carotenoid in primary leaves, and the anthocyanin in seedlings. While significant changes in chlorophyll and carotenoid accumulation were not observed during the initial 2 to 4 days of cultivation, by day 4 the seedlings grown on the clinostat had lower levels of anthocyanin, compared to those in the control seedlings. To further detail the cause for the observed reduction in anthocyanin accumulation under altered gravity conditions, seedlings were grown in the presence of silver nitrate, a known ethylene inhibitor, for 4 days, since it is known ethylene has a negative impact on anthocyanin accumulation. Silver nitrate promoted anthocyanin accumulation in the clinostat seedlings, and as a result there was no significant difference between the control and clinostat seedlings in anthocyanin accumulation. The results suggest that slow clinorotation negatively impacts anthocyanin pigmentation in mung bean seedlings, with endogenous ethylene suspected to be involved in this.

The invasive Asian shore crab, Hemigrapsus sanguineus, has recently been observed occupying salt marshes, a novel environment for this crab species. As it invades this new habitat, it is likely to interact with a number of important salt marsh species. To understand the potential effects of H. sanguineus on this ecosystem, interactions between this invasive crab and important salt marsh ecosystem engineers were examined. Laboratory experiments demonstrated competition for burrows between H. sanguineus and the native fiddler crab, Uca pugilator. Results indicate that H. sanguineus is able to displace an established fiddler crab from its burrow. Feeding experiments revealed that the presence of H. sanguineus has a significantly negative impact on the number as well as the biomass of ribbed mussels (Geukensia demissa) consumed by the green crab, Carcinus maenas, although this only occurred at high predator densities. In addition, when both crabs foraged together, there was a significant shift in the size of mussels consumed. These interactions suggests that H. sanguineus may have long-term impacts and wide-ranging negative effects on the saltmarsh ecosystem. PMID:25071995

The zinc finger proteins Mig1 and Mig2 play important roles in glucose repression of Saccharomyces cerevisiae. To investigate whether the alleviation of glucose effect would result in an increase in aerobic succinate production, MIG1 and/or MIG2 were disrupted in a succinate dehydrogenase (SDH)-negative S. cerevisiae strain. Moreover, their impacts on physiology of the SDH-negative S. cerevisiae strain were studied under fully aerobic conditions when glucose was the sole carbon source. Our results showed that the succinate production for the SDH-negative S. cerevisiae was very low even under fully aerobic conditions. Furthermore, deletion of MIG1 and/or MIG2 did not result in an increase in succinate production in the SDH-negative S. cerevisiae strain. However, the synthesis of acetate was significantly affected by MIG1 deletion or in combination with MIG2 deletion. The acetate production for the mig1/mig2 double mutant BS2M was reduced by 69.72% compared to the parent strain B2S. In addition, the amount of ethanol produced by BS2M was slightly decreased. With the mig2 mutant BSM2, the concentrations of pyruvate and glycerol were increased by 26.23% and 15.28%, respectively, compared to the parent strain B2S.

The impact of the accumulated experience of the capsule endoscopy (CE) reader on the accuracy of this test is discussed. To determine whether the negative predictive value of CE findings changes along the learning curve. We reviewed the first 900 CE read by 3 gastroenterologists experienced in endoscopy over 8 years. These 900 CE were divided into 3 groups (300 CE each): group 1 consisted of the sum of the first 100 CE read by each of the 3 endoscopists; group 2, the sum of the second 100 and groups 3, the sum of the third 100. Patients with normal CE were monitored for at least 28 months to estimate the negative predictive value. A total of 54 (18%) CE in group 1, 58 (19.3%) in group 2 and 47 (15.6%) in group 3 were normal, although only 34 patients in group 1, 38 in group 2 and 36 in group 3 with normal CE completed follow up and were eventually studied. The negative predictive value was 88.2% in group 1, 89.5% in group 2 and 97% in group 3 (P>.05). The negative predictive value tended to increase, but remained high and did not change significantly after the first 100 when readers are experienced in conventional endoscopy and have preliminary specific training.

Rosenstein, Alan H; O'Daniel, Michelle

2006-07-01

There is a growing concern about the role of human factor issues and their effect on patient safety and clinical outcomes of care. Problems with disruptive behaviors negatively affect communication flow and team dynamics, which can lead to adverse events and poor quality outcomes. A 25-question survey tool was used to assess the status and significance of disruptive behaviors around perioperative services in a large metropolitan academic medical center. Results were analyzed and compared with those from a national databank to identify areas of concern and opportunities for improvement. Disruptive behaviors were a common occurrence in the perioperative setting. These types of behaviors were most prevalent in attending surgeons. Disruptive behaviors increased levels of stress and frustration, which impaired concentration, impeded communication flow, and adversely affected staff relationships and team collaboration. These events were perceived to increase the likelihood of medical errors and adverse events and to compromise patient safety and quality of care. Disruptive behaviors in the perioperative arena have a significant impact on team dynamics and communication flow, which can have a negative impact on patient care. Organizations need to recognize the prevalence and significance of disruptive behaviors and develop policies and processes to address the issue. Key areas of focus include recognition and awareness, organizational and cultural commitment, implementation of appropriate codes of behavior policies and procedures, and provision of education and training programs to discuss contributing factors and tools to build effective communication and team collaboration skills.

Strabismus and discrimination in children: are children with strabismus invited to fewer birthday parties?

To determine the social acceptance of children with strabismus by their peers and to determine the age at which the negative impact of strabismus on psychosocial interactions emerges. Photographs of six children were digitally altered in order to create pictures of identical twins except for the position of the eyes (orthotropic, exotropic and exotropic) and the colour of the shirt. One hundred and eighteen children aged 3-12 years were asked to select, for each of the six twin pairs, one of the twins to invite to their birthday party. The grouping of the pictures and the composition of the twin pairs were determined by Latin squares. Children younger than 6 years old did not make any significant distinctions between orthotropic children and children with strabismus. Respondents aged 6 years or older invited children with a squint to their birthday parties significantly less often than orthotropic children. The authors found no impact (p>0.1) of gender, of the colour of the shirt or of the type of strabismus, but did find a highly significant impact of age on the number of invited children with strabismus. Children aged 6 years or older with a visible squint seem to be less likely to be accepted by their peers. Because this negative attitude towards strabismus appears to emerge at approximately the age of 6 years, corrective surgery for strabismus without prospects for binocular vision should be performed before this age.

Arsenic (As) gets accumulated in plants via phosphorous transporters and water channels and interferes with nutrient and water uptake, adversely affecting growth and productivity. Although, Si and AM have been reported to combat arsenic stress, their comparative and interactive roles in ameliorating As V and As III toxicities have not been reported. Study evaluated effects of Si and Rhizophagus irregularis on growth, As uptake and yield under arsenate and arsenite stress in two pigeonpea genotypes (metal tolerant-Pusa 2002 and metal sensitive-Pusa 991). Higher As accumulation and translocation was observed in As III treated roots of Pusa 991 than those of Pusa 2002 when compared with As V. Roots were more negatively affected than shoots which led to a significant decline in nutrient uptake, leaf chlorophylls, and yield, with As III inducing more negative effects. Pusa 2002 established more effective mycorrhizal symbiosis and had higher biomass than Pusa 991. Si was more effective in inducing shoot biomass while AM inoculation significantly improved root biomass. AM enhanced Si uptake in roots and leaves in a genotype dependent manner. Combined application of Si and AM were highly beneficial in improving leaf water status, chlorophyll pigments, biomass, and productivity. Complete amelioration of negative impacts of both concentrations of As V and lower concentration of As III were recorded under +Si +AM in Pusa 2002. Results highlighted great potential of Si in improving growth and productivity of pigeonpea through R. irregularis under As V and As III stresses.

Brain drain? An examination of stereotype threat effects during training on knowledge acquisition and organizational effectiveness.

PubMed

Grand, James A

2017-02-01

Stereotype threat describes a situation in which individuals are faced with the risk of upholding a negative stereotype about their subgroup based on their actions. Empirical work in this area has primarily examined the impact of negative stereotypes on performance for threatened individuals. However, this body of research seldom acknowledges that performance is a function of learning-which may also be impaired by pervasive group stereotypes. This study presents evidence from a 3-day self-guided training program demonstrating that stereotype threat impairs acquisition of cognitive learning outcomes for females facing a negative group stereotype. Using hierarchical Bayesian modeling, results revealed that stereotyped females demonstrated poorer declarative knowledge acquisition, spent less time reflecting on learning activities, and developed less efficiently organized knowledge structures compared with females in a control condition. Findings from a Bayesian mediation model also suggested that despite stereotyped individuals "working harder" to perform well, their underachievement was largely attributable to failures in learning to "work smarter." Building upon these empirical results, a computational model and computer simulation is also presented to demonstrate the practical significance of stereotype-induced impairments to learning on the development of an organization's human capital resources and capabilities. The simulation results show that even the presence of small effects of stereotype threat during learning/training have the potential to exert a significant negative impact on an organization's performance potential. Implications for future research and practice examining stereotype threat during learning are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

In general, U.S. college students have low perceived susceptibility of acquiring HIV infection while 15–25 percent of youth have had negative perceptions towards HIV positive individuals. Factors associated with HIV stigma among college students were examined in a convenience sample of 200 students. Descriptive and inferential statistics were utilized to summarize the data. Only four percent of participants responded correctly to HIV transmission knowledge items. HIV transmission knowledge scores were significantly higher for participants who were single with partner and those who resided outside university residential dorms (p < 0.05). There was a significant negative correlation between composite HIV knowledge scores and stigma scores r = −0.18 (p < 0.05). After adjusting for confounders, a marginal significant negative linear relationship emerged (β = −0.09, p = 0.06) between HIV knowledge and stigma. HIV prevention education among college students needs to be addressed with nuance to minimize HIV knowledge gaps, stigma and student risk perception that impacts HIV prevention and stigma against those living with HIV.

Failure to comply with work ethics by employees working in Health Information Technology (HIT) Departments and their negative attitudes about organizational justice may have an adverse impact on patient satisfaction, quality of care, collecting health statistics, reimbursement, and management and planning at all levels of health care; it can also lead to unbearable damages to the health information system in the country. As so far there has been no research on HIT managers to assess the moral and ethical aspects of works and their relationship with organizational alienation and justice, this study aimed to evaluate the relationship between work ethics and organizational justice and alienation among the HIT managers. This study was performed in affiliated hospitals of Semnan University of medical sciences in Semnan, Iran, in 2015. In this study, a census method was used. The data collection tool was a researcher made questionnaire. There was a negative and significant relationship between work ethic and organizational alienation (B= - 0.217, P<0.001), and there was also a positive and significant relationship between work ethic and organizational justice (B= 0.580, P<0.001). There were negative and significant relationships among between education level and work ethic (B= - 0.215, P=0.034) and organizational justice (B=- 0.147, P=0.047). The results of this study showed that the managers' attitude toward justice and equality in the organization can affect their organizational commitment and loyalty and thus have a significant impact on the work ethics in the work environment. On the other hand, with increasing the education level of the managers, they will have higher expectation of the justice in the organization, and they feel that the justice is not observed in the organization.

The degree to which evidence-based program outcomes are affected by modifications is a significant concern in the implementation of interventions. The ongoing national implementation of an evidence-based HIV prevention program targeting grade six students in The Bahamas [Focus on Youth in The Caribbean (FOYC)] offers an opportunity to explore factors associated with teachers’ modification of FOYC lessons and to examine the impact of types and degrees of modifications on student outcomes. Data were collected in 2012 from 155 teachers and 3646 students in 77 government elementary schools. Results indicate that teachers taught 16 of 30 core activities, 24.5 of 46 total activities and 4.7 of 8 sessions. Over one-half of the teachers made modifications to FOYC core activities; one-fourth of the teachers modified 25% or more core activities that they taught (heavily modified FOYC). Omitting core activities was the most common content modification, followed by lengthening FOYC lessons with reading, writing assignments or role-play games, shortening core activities or adding educational videos. Mixed-effects modeling revealed that omitting core activities had negative impacts on all four student outcomes. Shortening core activities and adding videos into lessons had negative impacts on HIV/AIDS knowledge and/or intention to use condom protection. Heavy modifications (>1/4 core activities) were associated with diminished program effectiveness. Heavy modifications and omitting or shortening core activities were negatively related to teachers’ level of implementation. We conclude that poorer student outcomes were associated with heavy modifications. PMID:26297497

Irrigation offsets wheat yield reductions from warming temperatures

Tack, Jesse; Barkley, Andrew; Hendricks, Nathan

Temperature increases due to climate change are expected to cause substantial reductions in global wheat yields. However, uncertainty remains regarding the potential role for irrigation as an adaptation strategy to offset heat impacts. Here we utilize over 7000 observations spanning eleven Kansas field-trial locations, 180 varieties, and 29 years to show that irrigation significantly reduces the negative impact of warming temperatures on winter wheat yields. Dryland wheat yields are estimated to decrease about eight percent for every one-degree Celsius increase in temperature, yet irrigation completely offsets this negative impact in our sample. As in previous studies, we find that important interactions exist between heat stress and precipitation for dryland production. Here, uniquely, we observe both dryland and irrigated trials side-by-side at the same locations and find that precipitation does not provide the same reduction in heat stress as irrigation. This is likely to be because the timing, intensity, and volume of water applications influence wheat yields, so the ability to irrigate—rather than relying on rainfall alone—has a stronger influence on heat stress. We find evidence of extensive differences of water-deficit stress impacts across varieties. This provides some evidence of the potential for adapting to hotter and drier climate conditions using optimal variety selection. Overall, our results highlight the critical role of water management for future global food security. Water scarcity not only reduces crop yields through water-deficit stress, but also amplifies the negative effects of warming temperatures.

Currently, increasing attention is being paid to issues related to environmental protection, waste management, as well as to the development of polymers with useful properties. The research presented here involved preparation of hydrogels based on Beetosan® - a chitosan derived from the multi-stage processing of dead bees. Moreover, hydrogels were additionally modified with natural substances - i.e. bee pollen and extract of Salvia officinalis (sage) that are well known for the presence of many compounds with beneficial properties from a medical point of view. Materials have been first obtained by photopolymerization. Then, their surface morphology, wettability and cytotoxicity to selected cell lines have been determined. It can be stated that such combination of Beetosan® hydrogel matrix and the mentioned additives resulted in a preparation of polymers characterized by negative impact on cancer cells. Impact of hydrogels with sage is slightly more intense due to the presence of substances such as ursalic or rosmaric acid that are characterized to have anticancer activity. Such negative impact has not been observed in case of studies using fibroblasts. Furthermore, addition of natural substances into hydrogels resulted in a more homogeneous surface and in the decrease of wettability angle of the tested polymers. It can be concluded that the use of natural-derived reagents and synthesis of polymers using these reagents (as a result of environmentally friendly photopolymerization) yields materials with interesting properties for medical purposes, with particular emphasis on antitumor activity, and without significant negative impact on fibroblasts.

2012-02-01

The negative impact of demersal fishing gears on the marine environment may be mitigated by utilizing less damaging fishing gears. Within this context three queen scallop fishing gears were tested for their catch efficiencies and their environmental impact on benthos: a traditional 'Newhaven' dredge, a new dredge design with a rubber lip instead of the traditional teeth as its main new design feature and an otter trawl. Both, the new dredge and the otter trawl showed high catches and relatively low by-catches. Catches made with the traditional dredge were lower and contained larger amounts of non-target species. Both dredges primarily caught invertebrate species, while by-catches of the otter trawl were dominated by demersal fish. The impact of these gears on the benthic biota demonstrated that while no effects were detected for the otter trawl both dredges showed similar negative effects. Clear negative effects were evident for the brittlestar Ophiura ophiura while positive trends for the common starfish Asterias rubens and the hermit crab Pagurus bernhardus indicated scavenging effects. Due to its higher catch efficiency the new dredge caused less damage per unit catch compared to the traditional dredge, yet compared to the otter trawl it appears less environmentally friendly. However, the new dredge may be an alternative to the otter trawls for fisheries where the by-catch of demersal fish has been identified as a significant problem. Copyright © 2011 Elsevier Ltd.

Malignant bile duct obstruction is a common problem among cancer patients with hepatic or lymphatic metastases. Endoscopic retrograde cholangiography (ERC) with the placement of a stent is the method of choice to improve biliary flow. Only little data exist concerning the outcome of patients with malignant biliary obstruction in relationship to microbial isolates from bile. Bile samples were taken during the ERC procedure in tumor patients with biliary obstruction. Clinical data including laboratory values, tumor-specific treatment and outcome data were prospectively collected. 206 ERC interventions in 163 patients were recorded. In 43 % of the patients, systemic treatment was (re-) initiated after successful biliary drainage. A variety of bacteria and fungi was detected in the bile samples. One-year survival was significantly worse in patients from whom multiresistant pathogens were isolated than in patients, in whom other species were detected. Increased levels of inflammatory markers were associated with a poor one-year survival. The negative impact of these two factors was confirmed in multivariate analysis. In patients with pancreatic cancer, univariate analysis showed a negative impact on one-year survival in case of detection of Candida species in the bile. Multivariate analysis confirmed the negative prognostic impact of Candida in the bile in pancreatic cancer patients. Outcome in tumor patients with malignant bile obstruction is associated with the type of microbial biliary colonization. The proof of multiresistant pathogens or Candida, as well as the level of inflammation markers, have an impact on the prognosis of the underlying tumor disease.

2016-11-01

This study explores the relationship between the perceived impact of cancer among long-term breast cancer survivors, sociodemographic and clinical variables, and mental and physical health-related quality of life outcomes in Austria. One hundred and fifty-two long-term survivors of breast cancer (on average 13 years after initial diagnosis) completed three mailed surveys, including the Short Form-36 (SF-36), the Impact of Cancer (version 2) to assess the perceived positive and negative aspects of cancer survivorship, and a general sociodemographic and clinical questionnaire. Linear regression models were constructed to determine the effects of the perceived positive and negative impact of cancer on mental and physical health-related quality of life. Respondents reported a physical health status that centered on population norms for Austria, but scored lower on mental health status. After controlling for age, chemotherapy, exercise, and BMI, the positive impact of cancer was associated with improved physical functioning (p = 0.0014) and the negative impact of cancer was associated with poorer physical functioning (p < 0.0001). After controlling for age, marital status, the belief in emotional distress as a cause of cancer, and high stress levels, the negative impact of cancer was associated with poorer mental functioning (p < 0.0001). Higher perceived positive impact of cancer was not associated with improved mental functioning. Long-term survivors of breast cancer in Austria perceive both positive and negative impacts of breast cancer. These perceptions, in particular the negative impact of cancer, appear to influence, or are potentially influenced by, physical and mental health-related quality of life.

To compare the quality and funding source of studies concluding a negative economic impact of smoke-free policies in the hospitality industry to studies concluding no such negative impact. Researchers sought all studies produced before 31 August 2002. Articles published in scientific journals were located with Medline, Science Citation Index, Social Sciences Citation Index, Current Contents, PsychInfo, Econlit, and Healthstar. Unpublished studies were located from tobacco company websites and through internet searches. 97 studies that made statements about economic impact were included. 93% of the studies located met the selection criteria as determined by consensus between multiple reviewers. Findings and characteristics of studies (apart from funding source) were classified independently by two researchers. A third assessor blind to both the objective of the present study and to funding source also classified each study. In studies concluding a negative impact, the odds of using a subjective outcome measure was 4.0 times (95% confidence interval (CI) 1.4 to 9.6; p = 0.007) and the odds of not being peer reviewed was 20 times (95% CI 2.6 to 166.7; p = 0.004) that of studies concluding no such negative impact. All of the studies concluding a negative impact were supported by the tobacco industry. 94% of the tobacco industry supported studies concluded a negative economic impact compared to none of the non-industry supported studies. All of the best designed studies report no impact or a positive impact of smoke-free restaurant and bar laws on sales or employment. Policymakers can act to protect workers and patrons from the toxins in secondhand smoke confident in rejecting industry claims that there will be an adverse economic impact.

Negative affect, interpersonal perception, and binge eating behavior: An experience sampling study.

Etiological and maintenance models for disordered eating highlight the salience of negative affect and interpersonal dysfunction. This study employed a 14-day experience sampling procedure to assess the impact of negative affect and interpersonal perceptions on binge eating behavior. Young adult women (N = 40) with recurrent binge eating and significant clinical impairment recorded their mood, interpersonal behavior, and eating behaviors at six stratified semirandom intervals daily through the use of personal digital assistants. Although momentary negative affect was associated with binge eating behavior, average levels of negative affect over the experience sampling period were not, and interpersonal problems moderated the relationship between negative affect and binge eating. Interpersonal problems also intensified the association between momentary interpersonal perceptions and binge eating behavior. Lagged analyses indicated that previous levels of negative affect and interpersonal style also influence binge eating. The study findings suggest there may be important differences in how dispositional versus momentary experiences of negative affect are associated with binge eating. Results also highlight the importance of interpersonal problems for understanding relationships among negative affect, interpersonal perception, and binge eating behavior. These results offer several possibilities for attending to affective and interpersonal functioning in clinical practice. © 2015 Wiley Periodicals, Inc.

Abstract Negative impacts of tobacco result from human consumption and from tobacco-growing activities, most of which now occur in low- and middle-income countries. Malawi is the world’s largest producer of burley tobacco and its population is affected by the negative consequences of both tobacco consumption and production. In countries like Malawi, tobacco control refers to control of the tobacco supply chain, rather than control of consumption. We review the impact of tobacco cultivation, using Malawi as an example, to illustrate the economic, environmental, health and social issues faced by low- and middle-income countries that still produce significant tobacco crops. We place these issues in the context of the sustainable development goals (SDGs), particularly 3a which calls on all governments to strengthen the implementation of the World Health Organization Framework Convention on Tobacco Control. Other goals address the negative effects that tobacco cultivation has on development. The SDGs offer an opportunity for low- and middle-income countries that are dependent on tobacco production and that are not yet parties to the Convention, to reconsider joining the FCTC.

Three-dimensional kinematic data of bat and ball were recorded for 239 individual shots performed by twenty batsmen ranging from club to international standard. The impact location of the ball on the bat face was determined and assessed against the resultant instantaneous post-impact ball speed and measures of post-impact bat torsion and ball direction. Significant negative linear relationships were found between post-impact ball speed and the absolute distance of impact from the midline medio-laterally and sweetspot longitudinally. Significant cubic relationships were found between the distance of impact from the midline of the bat medio-laterally and both a measure of bat torsion and the post-impact ball direction. A "sweet region" on the bat face was identified whereby impacts within 2 cm of the sweetspot in the medio-lateral direction, and 4.5 cm in the longitudinal direction, caused reductions in ball speed of less than 6% from the optimal value, and deviations in ball direction of less than 10° from the intended target. This study provides a greater understanding of the margin for error afforded to batsmen, allowing researchers to assess shot success in more detail, and highlights the importance of players generating consistently central impact locations when hitting for optimal performance.

The objective of this paper is to examine the dynamic impact of urbanization, economic growth, energy consumption, and trade openness on CO 2 emissions in Nigeria based on autoregressive distributed lags (ARDL) approach for the period of 1971-2011. The result shows that variables were cointegrated as null hypothesis was rejected at 1 % level of significance. The coefficients of long-run result reveal that urbanization does not have any significant impact on CO 2 emissions in Nigeria, economic growth, and energy consumption has a positive and significant impact on CO 2 emissions. However, trade openness has negative and significant impact on CO 2 emissions. Consumption of energy is among the main determinant of CO 2 emissions which is directly linked to the level of income. Despite the high level of urbanization in the country, consumption of energy still remains low due to lower income of the majority populace and this might be among the reasons why urbanization does not influence emissions of CO 2 in the country. Initiating more open economy policies will be welcoming in the Nigerian economy as the openness leads to the reduction of pollutants from the environment particularly CO 2 emissions which is the major gases that deteriorate physical environment.

The impact of cognitive factors on academic achievement is well documented. However, little is known about the mediating and moderating effects of non-cognitive, motivational and situational factors on academic achievement among nursing students. The aim of this study is to explore the direct and/or indirect effects of academic self-concept on academic achievement, and examine whether intrinsic motivation moderates the negative effect of test anxiety on academic achievement. This descriptive-correlational study was carried out on a convenience sample of 170 undergraduate nursing students, in an academic college in northern Israel. Academic motivation, academic self-concept and test anxiety scales were used as measuring instruments. Bootstrapping with resampling strategies was used for testing multiple mediators' model and examining the moderator effect. A higher self-concept was found to be directly related to greater academic achievement. Test anxiety and intrinsic motivation were found to be significant mediators in the relationship between self-concept and academic achievement. In addition, intrinsic motivation significantly moderated the negative effect of test anxiety on academic achievement. The results suggested that institutions should pay more attention to the enhancement of motivational factors (e.g., self-concept and motivation) and alleviate the negative impact of situational factors (e.g., test anxiety) when offering psycho-educational interventions designed to improve nursing students' academic achievements.

Anticoagulation therapy is a life-enhancing therapy for patients who are at risk for embolic events secondary to atrial fibrillation, valve replacement, and other comorbidities. Clinicians are motivated to decrease the amount of time that patients are either under- or over-anticoagulated, common conditions that decrease patient safety at either extreme. The primary purpose of this descriptive study was to examine the relationship between personal life event factors as measured by Norbeck's Life Events Questionnaire, core demographics such as age and income, and anticoagulation regulation. Although many factors affect anticoagulation therapy, the precise impact of life events, positive or negative, is unknown. The salient findings of this study (n = 202) showed a small, though statistically significant, inverse relationship (r = -0.184, P < .01) between negative life events and decreased time within therapeutic international normalized ratio. Total Life Event scores showed a statistically significant inverse relationship (r = -0.159, P < .05) to international normalized ratio time within therapeutic level. Lower income was inversely associated with higher negative Life Event scores (r = -0.192, P < .01). The findings demonstrate the need for strategies that address the potential impact of life events in conjunction with coexisting screening measures used in anticoagulation clinics. Implications for this study are limited by lack of methodology documenting concurrent social support factors and limitations of the research tool to reflect life event issues specific to outpatient seniors.

To evaluate DNA fragmentation in morphologically normal sperm recovered from the same sample used for intracytoplasmic sperm injection (ICSI) and to correlate DNA damage with embryo quality and pregnancy outcome. Prospective study. Academic center. 36 infertile men participating in the ICSI program. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-fluorescein nick end labeling (TUNEL) assay and morphologic assessment by phase contrast. Simultaneous assessment of sperm morphology and DNA fragmentation by TUNEL assay was performed in the same cell, then the percentage of normal sperm with fragmented DNA (normal SFD) was correlated with embryo quality and pregnancy outcomes. A highly statistically significant negative correlation was found between the percentage of normal SFD and embryo quality. This association was confirmed for the transferred embryos and for the total embryo cohort. The receiver operating characteristics curve analysis demonstrated that the percentage of normal SFD and embryo quality were statistically significant predictors of pregnancy. When the percentage of normal SFD was

Forest fragmentation dramatically alters species persistence and distribution and affects many ecological interactions among species. Recent studies suggest that mutualisms, such as pollination and seed dispersal, are more sensitive to the negative effects of forest fragmentation than antagonisms, such as predation or herbivory. We applied meta-analytical techniques to evaluate this hypothesis and quantified the relative contributions of different components of the fragmentation process (decreases in fragment size, edge effects, increased isolation, and habitat degradation) to the overall effect. The effects of fragmentation on mutualisms were primarily driven by habitat degradation, edge effects, and fragment isolation, and, as predicted, they were consistently more negative on mutualisms than on antagonisms. For the most studied interaction type, seed dispersal, only certain components of fragmentation had significant (edge effects) or marginally significant (fragment size) effects. Seed size modulated the effect of fragmentation: species with large seeds showed stronger negative impacts of fragmentation via reduced dispersal rates. Our results reveal that different components of the habitat fragmentation process have varying impacts on key mutualisms. We also conclude that antagonistic interactions have been understudied in fragmented landscapes, most of the research has concentrated on particular types of mutualistic interactions such as seed dispersal, and that available studies of interspecific interactions have a strong geographical bias (arising mostly from studies carried out in Brazil, Chile, and the United States). © 2014 Society for Conservation Biology.

A computer-controlled touchscreen apparatus (hereafter referred to as "touchscreen") in the orangutan exhibit at Zoo Atlanta provides enrichment to the animals and allows cognitive research to take place on exhibit. This study investigated the impact of the touchscreen on orangutan behavior and visibility, as well as its impact on zoo visitors. Despite previous research suggesting that providing a single computer system may negatively affect orangutan behavior, there was not a significant increase in aggression, stereotypic, or distress-related behaviors following the activation of the on-exhibit touchscreen. We also investigated the possibility that zoo visitors may be negatively affected by technology because it deviates from naturalism. However, we did not find a change in stay time or overall experience rating when the computer was turned on. This research was the first to assess visitor attitudes toward technology at the zoo, and we found that visitors report highly positive attitudes about technology for both animals and visitors. If subjects visited the exhibit when the computer was turned on, they more strongly agreed that orangutans benefit from interacting with computerized enrichment. This study is the first investigation of an on-exhibit touchscreen in group-housed apes; our findings of no negative effects on the animals or zoo visitors and positive attitudes toward technology suggest a significant value of this practice. © 2011 Wiley Periodicals, Inc.

This study examined several dimensions of early father–daughter relationship as predictors of marital satisfaction among 494 respondents. Descriptive comparative approach was used in result analysis. The Father Presence Questionnaire and Marital Satisfaction Questionnaire were used, in addition to a number of demographic variables. Results showed that only physical relationship with the father, and perceptions of father’s influence, had a positive significant impact on wives’ marital satisfaction. Of all domains, only positive feelings about the father had a negative impact on the husband’s marital satisfaction. Most demographic variables had statistically significant effect on marital satisfaction. Sociocultural implications for marital satisfaction for wives and husbands are discussed. PMID:27114719

Obesity & osteoarthritis

King, Lauren K.; March, Lyn; Anandacoomarasamy, Ananthila

2013-01-01

The most significant impact of obesity on the musculoskeletal system is associated with osteoarthritis (OA), a disabling degenerative joint disorder characterized by pain, decreased mobility and negative impact on quality of life. OA pathogenesis relates to both excessive joint loading and altered biomechanical patterns together with hormonal and cytokine dysregulation. Obesity is associated with the incidence and progression of OA of both weight-bearing and non weight-bearing joints, to rate of joint replacements as well as operative complications. Weight loss in OA can impart clinically significant improvements in pain and delay progression of joint structural damage. Further work is required to determine the relative contributions of mechanical and metabolic factors in the pathogenesis of OA. PMID:24056594

The preliminary investigation at shoreline along Taihu lake with different degrees of eutrophication status found no significant relationship between the microcystin-LR concentrations and the freshwater snail Bellamya aeruginosa fecundity or the abundance of wild freshwater snails. To further confirm the impact of eutrophication on the reproductive ability of snails, ecological mesocosm experiments were employed at four sites in Taihu lake during the algal blooming period, and no significant relationship was also found between MC-LR concentrations and snail fecundity. These results implied that eutrophication does not negatively or positive affect snail fecundity in Taihu Lake, a typical eutrophication lake in China. Copyright © 2018 Elsevier B.V.

The diagnosis of periodontal disease is commonly based on objective evaluations of the patient's medical/dental history as well as clinical and radiographic examinations. However, periodontal disease should also be evaluated subjectively through measures that quantify its impact on oral health-related quality of life. The aim of this study was to evaluate the impact of periodontal disease on quality of life among adolescents, adults and older adults. A systematic search of the literature was performed for scientific articles published up to July 2015 using electronic databases and a manual search. Two independent reviewers performed the selection of the studies, extracted the data and assessed the methodological quality. Thirty-four cross-sectional studies involving any age group, except children, and the use of questionnaires for the assessment of the impact of periodontal disease on quality of life were included. Twenty-five studies demonstrated that periodontal disease was associated with a negative impact on quality of life, with severe periodontitis exerting the most significant impact by compromising aspects related to function and esthetics. Unlike periodontitis, gingivitis was associated with pain as well as difficulties performing oral hygiene and wearing dentures. Gingivitis was also negatively correlated with comfort. The results indicate that periodontal disease may exert an impact on quality of life of individuals, with greater severity of the disease related to greater impact. Longitudinal studies with representative samples are needed to ensure validity of the findings. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

A Study of the Impact of Thirteen Celebrity Suicides on Subsequent Suicide Rates in South Korea from 2005 to 2009

2013-01-01

A number of ecological studies have found a pattern of increasing suicide rates after suicides of several Asian entertainment celebrities. However, the finding may be subject to positive outcome bias where cases with no perceived impact may be routinely excluded. In this study, we deploy interrupted time-series analysis using ARIMA transfer function models to investigate systematically the impact of thirteen celebrity suicides on subsequent suicide rates in South Korea. We find that three out of eleven cases were found to be followed by a significant increase in suicide rate, while controlling for seasonality, secular trends, and unemployment rates. Such significant increases could last for nine weeks. Non-significance cases may be attributable to the small amount of media coverage, the “displacement” effect of preceding case, and the negative connotation of celebrity deaths. We therefore conclude that whether or not the impacts were detected may be largely conditioned by various contextual factors. Current evidence based on ecological studies is insufficient to draw a firm conclusion. Further studies using multiple approaches should be developed. PMID:23342026

This study involved the examination of the relationship between childhood trauma and both psychotic symptoms and suicidality in patients with schizophrenia after controlling for the possible confounding factors, such as clinical features, depression, and sleep quality. The Childhood Trauma Questionnaire-Short Form, Positive and Negative Syndrome Scale (PANSS), Calgary Depression Scale for Schizophrenia (CDSS), Pittsburgh Sleep Quality Index (PSQI), and the suicidality subscale of Mini-International Neuropsychiatric Interview (MINI) were administered to 199 patients with schizophrenia. We used sequential multiple stepwise regression analyses in which positive symptoms, negative symptoms, overall psychopathology, total symptoms of schizophrenia, and suicidality were dependent variables. Depressive symptomatology and childhood physical abuse significantly contributed to positive, negative, general psychopathology, and global schizophrenia symptomatology. Interestingly, general psychopathology scores were negatively associated with childhood physical neglect. Also, subjective sleep quality significantly contributed to positive schizophrenia symptoms. Although prior suicide attempts and depression were significant antecedents of suicidal ideation, no association between suicidality and both childhood trauma and sleep was found. Childhood physical abuse could have an impact on psychopathology in schizophrenia. In addition to childhood trauma, depression, sleep disturbances, and clinical features should be considered and inquired about in the course of clinical care of schizophrenia patients.

Cooperation degradation can be seen as one of the main causes of human errors. Poor cooperation could arise from aberrant mental processes, such as mental overload, that negatively affect the user's performance. Using different levels of difficulty in a cooperative task, we combined behavioural, subjective and neurophysiological data with the aim to i) quantify the mental workload under which the crew was operating, ii) evaluate the degree of their cooperation, and iii) assess the impact of the workload demands on the cooperation levels. The combination of such data showed that high workload demand impacted significantly on the performance, workload perception, and degree of cooperation.

2017-10-01

Landfill is one of the most common, widely used waste management technique in Malaysia. The ever increasing of solid waste has made the role of landfill become prominent despite the negative impacts that caused by the landfill is unavoidable. The public and government regulations are getting more aware with the negative impacts that could be brought by the landfill towards the community. It led to the cultural shift to integrate the concept of sustainability into the planning of siting a landfill in an urban area. However, current urban planning tends to emphasize more on the environmental aspect instead of social and economic aspects. This is due to the existing planning guidelines and stakeholder’s understandings are more on the environmental aspect. This led to the needs of incorporating the concept of sustainability into the urban planning. Thus, this paper focuses on the industry stakeholders view on the negative impacts that will cause by the landfill towards the urban planning. The industry stakeholders are those who are related to the decision-making in the selection of a landfill site in the government department. The scope of the study is within the country of Malaysia. This study was conducted through the semi-structured interviews with a total of fifteen industry stakeholders to obtain their perspective on the issues of impacts of siting a landfill in the urban area. The data obtained was analysed using the software, QSR NVivo version 10. Results indicate that landfill bought significant sustainability-related impacts towards landfill siting in urban planning. The negative impacts stated by the respondents are categorized under all three sustainable aspects such as environmental, social and economic. Among the results are such as the pollution, such as the generation of leachate, the objection in siting a landfill site against by the public, and the negotiating and getting money contribution from local authorities. The results produced can be served as a guideline for the industry stakeholders to have a holistic overview of the impacts that could lead by the landfill in siting into the urban area in terms of sustainability aspects. Moreover, it serves as a platform for the developing a holistic guideline for urban planning in the consideration of sustainability aspect of the selection for a landfill site.

Workplace bullying is an occupational hazard for trainee doctors. However, little is known about their experiences of cyberbullying at work. This study examines the impact of cyberbullying among trainee doctors, and how attributions of blame for cyberbullying influence individual and work-related outcomes. Doctors at over 6 months into training were asked to complete an online survey that included measures of cyberbullying, blame attribution, negative emotion, job satisfaction, interactional justice and mental strain. A total of 158 trainee doctors (104 women, 54 men) completed the survey. Overall, 73 (46.2%) respondents had experienced at least one act of cyberbullying. Cyberbullying adversely impacted on job satisfaction (β = - 0.19; p < 0.05) and mental strain (β = 0.22; p < 0.001), although attributions of blame for the cyberbullying influenced its impact and the path of mediation. Negative emotion mediated the relationship between self-blame for a cyber-bullying act and mental strain, whereas interactional injustice mediated the association between blaming the perpetrator and job dissatisfaction. Acts of cyberbullying had been experienced by nearly half of the sample during their training and were found to significantly relate to ill health and job dissatisfaction. The deleterious impact of cyberbullying can be addressed through both workplace policies, and training for trainee doctors and experienced medical professionals. © 2015 John Wiley & Sons Ltd.

Coaching to vision versus coaching to improvement needs: a preliminary investigation on the differential impacts of fostering positive and negative emotion during real time executive coaching sessions

2015-01-01

Drawing on intentional change theory (ICT; Boyatzis, 2006), this study examined the differential impact of inducing coaching recipients’ vision/positive emotion versus improvement needs/negative emotion during real time executive coaching sessions. A core aim of the study was to empirically test two central ICT propositions on the effects of using the coached person’s Positive Emotional Attractor (vision/PEA) versus Negative Emotional Attractor (improvement needs/NEA) as the anchoring framework of a onetime, one-on-one coaching session on appraisal of 360° feedback and discussion of possible change goals. Eighteen coaching recipients were randomly assigned to two coaching conditions, the coaching to vision/PEA condition and the coaching to improvement needs/NEA condition. Two main hypotheses were tested. Hypothesis1 predicted that participants in the vision/PEA condition would show higher levels of expressed positive emotion during appraisal of 360° feedback results and discussion of change goals than recipients in the improvement needs/NEA condition. Hypothesis2 predicted that vision/PEA participants would show lower levels of stress immediately after the coaching session than improvement needs/NEA participants. Findings showed that coaching to vision/the PEA fostered significantly lower levels of expressed negative emotion and anger during appraisal of 360° feedback results as compared to coaching to improvements needs/the NEA. Vision-focused coaching also fostered significantly greater exploration of personal passions and future desires, and more positive engagement during 360° feedback appraisal. No significant differences between the two conditions were found in emotional processing during discussion of change goals or levels of stress immediately after the coaching session. Current findings suggest that vision/PEA arousal versus improvement needs/NEA arousal impact the coaching process in quite different ways; that the coach’s initial framing of the session predominantly in the PEA (or, alternatively, predominantly in the NEA) fosters emotional processing that is driven by this initial framing; and that both the PEA (and associated positive emotions) and NEA (and associated negative emotions) play an important and recurrent role in shaping the change process. Further study on these outcomes will enable researchers to shed more light on the differential impact of the PEA versus NEA on intentional change, and how to leverage the benefits of both emotional attractors. Findings also suggest that coaches can benefit from better understanding the importance of tapping intrinsic motivation and personal passions through coaching to vision/the PEA. Coaches additionally may benefit from better understanding how to leverage the long-term advantages, and restorative benefits, of positive emotions during coaching engagements. The findings also highlight coaches’ need to appreciate the impact of timing effects on coaching intentional change, and how coaches can play a critical role in calibrating the pace and focus of work on intentional change. Early arousal of the coachee’s PEA, accompanied by recurrent PEA–NEA induction, may help coachees be/become more creative, optimistic, and resilient during a given change process. Overall, primary focus on vision/PEA and secondary focus on improvement needs/NEA may better equip coaches and coaching recipients to work together on building robust learning, development, and change.

2013-07-01

Tourette syndrome (TS) is a neuropsychiatric developmental disorder characterized by the presence of multiple motor tics and one or more vocal tics. Although TS is primarily biological in origin, stress-diatheses interactions most probably play a role in the course of the illness. The precise influence of the environment on this basically biological disorder is difficult to ascertain, particularly when TS is complicated by comorbidities. Among the many questions that remain unresolved are the differential impact of positive and negative events and specific subtypes of events, and the importance of major crucial events relative to minor daily ones to tic severity. To examine the relationships between life events, tic severity and comorbid disorders in Tourette Syndrome (TS), including OCD, ADHD, anxiety, depression and rage attacks. Life events were classified by quantity, quality (positive or negative) and classification types of events (family, friends etc.). Sixty patients aged 7-17 years with Tourette syndrome or a chronic tic disorder were recruited from Psychological Medicine Clinic in Schneider Children's Medical Center of Israel. Yale Global Tic Severity Scale; Children's Yale Brown Obsessive Compulsive Scale; Life Experiences Survey; Brief Adolescent Life Events Scale; Screen for Child Anxiety Related Emotional Disorders; Child Depression Inventory/Beck Depression Inventory; ADHD Rating Scale IV; Overt Aggression Scale. Regarding tics and minor life events, there was a weak but significant correlation between severity of motor tics and the quantity of negative events. No significant correlation was found between tic severity and quantity of positive events. Analysis of the BALES categories yielded a significant direct correlation between severity of vocal tics and quantity of negative events involving friends. Regarding comorbidities and minor life events, highly significant correlations were found with depression and anxiety. Regarding tics and major life events, significant correlation was found between the quantity of major life events and the severity of motor tics, but not vocal tics. Regarding comorbidities and major life events, significant correlation was found between the severity of compulsions, ADHD, and aggression and the subjects' personal evaluation of the effect of negative major life events on their lives. Minor life events appear to be correlated with tic severity and comorbidities in children and adolescents with Tourette syndrome. The lack of an association between major life events and tic severity further emphasizes the salient impact of minor life events that occur in temporal proximity to the assessment of tic severity. Clinically, the results match our impression from patient narratives wherein they "blamed" the exacerbations in tics on social interactions. The high correlation between negative life events and depression, anxiety and compulsions symptoms, were reported also in previous studies. In conclusion, These findings may have clinical implications for planning supportive psychotherapy or cognitive behavioral therapy for this patient population. Copyright © 2013 Elsevier Inc.

Intense tourism and human activities have resulted in habitat destruction in sandy beach ecosystems with negative impacts on the associated communities. To investigate whether urbanized beaches affect surf zone fish communities, fish and their benthic macrofaunal prey were collected during periods of low and high human pressure at two beaches on the Southeastern Brazilian coast. A BACI experimental design (Before-After-Control-Impact) was adapted for comparisons of tourism impact on fish community composition and structure in urbanized, intermediate and non-urbanized sectors of each beach. At the end of the summer season, we observed a significant reduction in fish richness, abundance, and diversity in the high tourist pressure areas. The negative association between visitors' abundance and the macrofaunal density suggests that urbanized beaches are avoided by surf zone fish due to higher human pressure and the reduction of food availability. Our results indicate that surf zone fish should be included in environmental impact studies in sandy beaches, including commercial species, e.g., the bluefish Pomatomus saltatrix. The comparative results from the less urbanized areas suggest that environmental zoning and visitation limits should be used as effective management and preservation strategies on beaches with high conservation potential.

In Europe, Bt-corn resistant against the European Corn Borer has until now been the only genetically modified plant to be grown commercially. With the advent of the Western Corn Rootworm Bt-corn varieties with resistance against Coleoptera will become important. The cultivation of Bt-plants may have negative impacts on non-target organisms, i.e. all species not explicitly targeted by a given Bt-crop. One prominent non-target group in corn are the herbivorous plant bugs (Heteroptera: Miridae). They are common, abundant and exposed to the Cry-protein. We therefore assessed the potential impact of the cultivation of the Cry3Bb1-expressing Bt-corn variety MON88017 and three conventional varieties on this group. Trigonotylus caelestialium (Kirkaldy) was the most abundant plant bug at the experimental field. There was no evidence for a negative impact of MON88017 on this species, despite its considerable exposure to Cry3Bb1 demonstrated with ELISA. The conventional corn varieties, however, had a consistent and significant influence on the field densities of this species over all three growing seasons.

Climate change would cause negative impacts on future agricultural production and food security. Adaptive measures should be taken to mitigate the adverse effects. The objectives of this study were to simulate the potential effects of climate change on maize yields in Heilongjiang Province and to evaluate two selected typical household-level autonomous adaptive measures (cultivar changes and planting time adjustments) for mitigating the risks of climate change based on the CERES-Maize model. The results showed that flowering duration and maturity duration of maize would be shortened in the future climate and thus maize yield would reduce by 11-46% during 2011-2099 relative to 1981-2010. Increased CO2 concentration would not benefit maize production significantly. However, substituting local cultivars with later-maturing ones and delaying the planting date could increase yields as the climate changes. The results provide insight regarding the likely impacts of climate change on maize yields and the efficacy of selected adaptive measures by presenting evidence-based implications and mitigation strategies for the potential negative impacts of future climate change. © 2014 Society of Chemical Industry.

We examined the psychological impact of the 2003 outbreak of severe acute respiratory syndrome (SARS) on hospital employees in Beijing, China. In 2006, randomly selected employees (n = 549) of a hospital in Beijing were surveyed concerning their exposure to the 2003 SARS outbreak, and the ways in which the outbreak had affected their mental health. About 10% of the respondents had experienced high levels of posttraumatic stress (PTS) symptoms since the SARS outbreak. Respondents who had been quarantined, or worked in high-risk locations such as SARS wards, or had friends or close relatives who contracted SARS, were 2 to 3 times more likely to have high PTS symptom levels, than those without these exposures. Respondents' perceptions of SARS-related risks were significantly positively associated with PTS symptom levels and partially mediated the effects of exposure. Altruistic acceptance of work-related risks was negatively related to PTS levels. The psychological impact of stressful events related to an infectious disease outbreak may be mediated by peoples' perceptions of those events; altruism may help to protect some health care workers against these negative impacts.

Many researches showed that climate change has significant impact on agricultural sector, which threats the food security especially in developing countries. It has been observed also that the climate change increases the intensity of extreme events. This research investigated the impact climate to the agricultural productivity in East Java, as one of the main rice producers in Indonesia. Standard regression as well as panel regression models have been performed in order to find the best model which is able to describe the climate change impact. The analysis found that the fixed effect model of panel regression outperforms the others showing that climate change had negatively impacted the rice productivity in East Java. The effect in Malang and Pasuruan were almost the same, while the impact in Sumenep was the least one compared to other districts.

The impact of televised tobacco control advertising content on campaign recall: Evidence from the International Tobacco Control (ITC) United Kingdom Survey

PubMed Central

2014-01-01

Background Although there is some evidence to support an association between exposure to televised tobacco control campaigns and recall among youth, little research has been conducted among adults. In addition, no previous work has directly compared the impact of different types of emotive campaign content. The present study examined the impact of increased exposure to tobacco control advertising with different types of emotive content on rates and durations of self-reported recall. Methods Data on recall of televised campaigns from 1,968 adult smokers residing in England through four waves of the International Tobacco Control (ITC) United Kingdom Survey from 2005 to 2009 were merged with estimates of per capita exposure to government-run televised tobacco control advertising (measured in GRPs, or Gross Rating Points), which were categorised as either “positive” or “negative” according to their emotional content. Results Increased overall campaign exposure was found to significantly increase probability of recall. For every additional 1,000 GRPs of per capita exposure to negative emotive campaigns in the six months prior to survey, there was a 41% increase in likelihood of recall (OR = 1.41, 95% CI: 1.24–1.61), while positive campaigns had no significant effect. Increased exposure to negative campaigns in both the 1–3 months and 4–6 month periods before survey was positively associated with recall. Conclusions Increased per capita exposure to negative emotive campaigns had a greater effect on campaign recall than positive campaigns, and was positively associated with increased recall even when the exposure had occurred more than three months previously.

Invasive ecosystem engineers (IEE) are potentially one of the most influential types of biological invaders. They are expected to have extensive ecological impacts by altering the physical-chemical structure of ecosystems, thereby changing the rules of existence for a broad range of resident biota. To test the generality of this expectation, we used a global systematic review and meta-analysis to examine IEE effects on the abundance of individual species and communities, biodiversity (using several indices) and ecosystem functions, focusing on marine and estuarine environments. We found that IEE had a significant effect (positive and negative) in most studies testing impacts on individual species, but the overall (cumulative) effect size was small and negative. Many individual studies showed strong IEE effects on community abundance and diversity, but the direction of effects was variable, leading to statistically non-significant overall effects in most categories. In contrast, there was a strong overall effect on most ecosystem functions we examined. IEE negatively affected metabolic functions and primary production, but positively affected nutrient flux, sedimentation and decomposition. We use the results to develop a conceptual model by highlighting pathways whereby IEE impact communities and ecosystem functions, and identify several sources of research bias in the IEE-related invasion literature. Only a few of the studies simultaneously quantified IEE effects on community/diversity and ecosystem functions. Therefore, understanding how IEE may alter biodiversity-ecosystem function relationships should be a primary focus of future studies of invasion biology. Moreover, the clear effects of IEE on ecosystem functions detected in our study suggest that scientists and environmental managers ought to examine how the effects of IEE might be manifested in the services that marine ecosystems provide to humans. © 2017 John Wiley & Sons Ltd.

The aim of our study was to evaluate factors affecting cystic fibrosis (CF) patients' health-related quality of life (HRQoL) and to assess the level of agreement on HRQol between children and their parents. Fifty-nine patients (mean age: 14.03 ± 4.81 years) from 5 Hungarian CF centres completed the survey. HRQoL was measured using The Cystic Fibrosis Questionnaire-Revised (CFQ-R). Parents were asked to fill out a questionnaire about their smoking habits, educational level and history of chronic illness. Disease severity was assessed using the physician-reported Shwachman-Kulczycki (SK) score system. Spirometry, Body Mass Index (BMI) percentile (pc), hospitalisation and Pseudomonas aeruginosa (PA) infection were examined as physiologic parameters of CF, and the impact of these factors on HRQoL was assessed. A multivariate regression analysis was performed to identify the most important factors affecting HRQoL. The level of significance was set to 0.05. Passive smoking and parental educational level and chronic diseases status did not have a significant impact on the patients' HRQoL (p > 0.05). Significantly lower SK scores and spirometry values were found in low BMI pc patients (p < 0.001), in hospitalised (p < 0.01) and in PA-infected patients (p < 0.01), than in the adequate-weight, non-hospitalised and PA culture-negative subgroup. Lower CFQ-R scores were detected in hospitalised patients than in non-hospitalised patients in their Physical functioning domain. PA-infected patients had HRQoL scores that were significantly worse in the Body image (p < 0.01) and Respiratory symptoms (p < 0.05) domains than the PA culture-negative patients. Patients with a low BMI pc (<25th BMI pc) had significantly lower scores in the Eating, Body image and Treatment burden domains, than the adequate-weight patients (>25th BMI pc) (p < 0.01). A strong child-parent agreement was found in the Physical functioning domain (r = 0.77, p < 0.01). Passive smoking, parental educational level and chronic diseases of parents do not affect the HRQoL of CF patients. In contrast, hospitalisation, PA infection and malnutrition have a significant and negative impact on patients' HRQoL and the clinical severity of the disease. Parents and children were consistent in their scoring of symptoms and behaviours that were observable.

This research investigated the role of Islamic appraisals, trauma-related appraisals, and religious coping in Muslim trauma survivors. We report 2 studies of Muslim trauma survivors with and without posttraumatic stress disorder (PTSD) living in the United Kingdom (Study 1) and a sample of Muslim trauma survivors living in Northern Iraq (Study 2). In both studies participants completed the Posttraumatic Stress Diagnostic Scale, Brief Religious Coping Scale, Islamic Appraisal Questionnaire, and Posttraumatic Cognitions Inventory in Arabic. First, it was found that negative religious coping differentiated between trauma survivors with and without PTSD (Study 1) and was significantly correlated with PTSD symptoms (Study 2). Second, negative Islamic appraisals were significantly associated with greater PTSD symptoms whereas positive Islamic appraisals were significantly associated with fewer PTSD symptoms (Study 2). Third, negative trauma-related appraisals correlated significantly with, and uniquely predicted, PTSD symptoms (Study 2). Finally, trauma-related appraisals were found to mediate the relationship between negative Islamic appraisals and negative religious coping and PTSD symptoms. These findings suggest that the theoretical emphasis on trauma-related cognitions may also be applicable to our understanding of PTSD in Muslim trauma survivors. However, for this population, trauma-related appraisals and subsequent coping strategies may be influenced by Islamic beliefs and values. Clinically, our findings suggest that addressing PTSD symptoms in Muslim trauma survivors may require clinicians to consider the impact of trauma on the survivor's religious appraisals and relationship with God.

Objective Based on conceptual models of addiction and affect regulation, this study examined the mechanisms linking current major depressive syndrome (MDS) and anxiety syndrome (AS) to postpartum smoking relapse. Method Data were collected in a randomized clinical trial from 251 women who quit smoking during pregnancy. Simple and multiple mediation models of the relations of MDS and AS with postpartum relapse were examined using linear regression, continuation ratio logit models, and a Bootstrapping procedure to test the indirect effects. Results Both MDS and AS significantly predicted postpartum smoking relapse. After adjusting for MDS, AS significantly predicted relapse. However, after adjusting for AS, MDS no longer predicted relapse. Situationally-based self-efficacy, expectancies of controlling negative affect by means other than smoking, and various dimensions of primary and secondary tobacco dependence individually mediated the effect of both MDS and AS on relapse. In multiple mediation models, self-efficacy in negative/affective situations significantly mediated the effect of MDS and AS on relapse. Conclusion The findings underscore the negative impact of depression and anxiety on postpartum smoking relapse, and suggest that the effects of MDS on postpartum relapse may be largely explained by comorbid AS. The current investigation provided mixed support for affect regulation models of addiction. Cognitive and tobacco dependence-related aspects of negative and positive reinforcement significantly mediated the relationship of depression and anxiety with relapse, while affect and stress did not. The findings emphasize the unique role of low agency with respect to abstaining from smoking in negative affective situations as a key predictor of postpartum smoking relapse. PMID:22390410

Preparing for what might happen: An episodic specificity induction impacts the generation of alternative future events.

Jing, Helen G; Madore, Kevin P; Schacter, Daniel L

2017-12-01

A critical adaptive feature of future thinking involves the ability to generate alternative versions of possible future events. However, little is known about the nature of the processes that support this ability. Here we examined whether an episodic specificity induction - brief training in recollecting details of a recent experience that selectively impacts tasks that draw on episodic retrieval - (1) boosts alternative event generation and (2) changes one's initial perceptions of negative future events. In Experiment 1, an episodic specificity induction significantly increased the number of alternative positive outcomes that participants generated to a series of standardized negative events, compared with a control induction not focused on episodic specificity. We also observed larger decreases in the perceived plausibility and negativity of the original events in the specificity condition, where participants generated more alternative outcomes, relative to the control condition. In Experiment 2, we replicated and extended these findings using a series of personalized negative events. Our findings support the idea that episodic memory processes are involved in generating alternative outcomes to anticipated future events, and that boosting the number of alternative outcomes is related to subsequent changes in the perceived plausibility and valence of the original events, which may have implications for psychological well-being.

The mainstay of treatment in adenoid cystic carcinoma (ACC) of the head and neck is surgical resection with negative margins. The purpose of this study was to define the margin status that associates with survival outcomes of ACC of the head and neck. We conducted univariate and multivariate analyses of international data. Data of 507 patients with ACC of the head and neck were analyzed; negative margins defined as ≥5 mm were detected in 253 patients (50%). On multivariate analysis, the hazard ratios (HRs) of positive margin status were 2.68 (95% confidence interval [CI], 1.2-6.2; p = .04) and 2.63 (95% CI, 1.1-6.3; p = .03) for overall survival (OS) and disease-specific survival (DSS), respectively. Close margins had no significant impact on outcome, with HRs of 1.1 (95% CI, 0.4-3.0; p = .12) and 1.07 (95% CI, 0.3-3.4; p = .23) for OS and DSS, respectively, relative with negative margins. In head and neck ACC, positive margins are associated with the worst outcome. Negative or close margins are associated with improved outcome, regardless of the distance from the tumor. © 2017 Wiley Periodicals, Inc.

The Relationship Between Experiences of Lateral Violence and Career Choice Satisfaction Among Nursing Students.

PubMed

Furst, Cari

This article explores associate degree nursing students' experiences with lateral violence and its impact on career choice satisfaction. Lateral violence has been linked to decreased professional identity, increased errors, and poor self-esteem, leading to a negative culture and attrition. A nonexperimental, quantitative, cross-sectional, correlational design was used; 13.4 percent of respondents (n = 32) met the criteria for intermittent bullying. Analysis confirmed a significant negative correlation between experiences of lateral/vertical violence and career choice satisfaction (r = - .140, p < .05) even after controlling for affect and support. Improved efforts are needed to prevent lateral violence.

We examined the association between telomere length and prenatal tobacco exposure (PTE) in 104 children aged 4 to 14 years. Salivary telomere length (STL) was determined from salivary DNA using quantitative polymerase chain reaction. Of the children, 18% had maternal reported PTE. Mean STL was significantly lower among children with PTE (6.4 vs 7.5, P < .05). Findings extend the literature demonstrating the negative long-term effects of PTE to include a cellular marker of aging linked to multiple negative health outcomes. PMID:23927510

Using data from the Baltimore Police Stress and Domestic Violence study, the authors examined how exposure to stressful events on the job affects law enforcement employees' physical aggression toward domestic partners, evaluating the role of negative emotions and authoritarian spillover in mediating the impact of such task-related stress. The authors consulted general strain theory and angry aggression theory to explain domestic violence in police families. Significant positive effects on physical aggression toward an intimate partner were found for variables measuring authoritarian spillover and negative emotions. However, these effects were different for different gender and racial groups.

A growing body of literature has shown that being victimized online is associated with poor mental health. Little is known about the factors that protect youth from the negative outcomes that may result from these victimization experiences, particularly those related to race. Using a risk and resilience framework, this study examined the protective function of ethnic identity and self-esteem among African Americans who experience online racial discrimination. For the sample of 125 adolescents, hierarchical regression results revealed that higher levels of ethnic identity and self-esteem significantly moderated the negative impact of online racial discrimination on anxiety levels. These findings show that ethnic identity and self-esteem can buffer the negative mental health outcomes associated with online racial discrimination, at least with respect to adolescents' anxiety. Findings from the current study have significant implications for adolescent adjustment given the increased time youth spend doing online activities.

Mental health authorities must know the public's attitude to community psychiatry when planning community mental health services. However, previous studies have only investigated the impact of demographic variables on the attitude to community psychiatry. To assess the influence of psychological and sociological parameters on the public opinion of community psychiatry in Switzerland. Linear regression analyses of the results of a public opinion survey on a representative population sample in Switzerland (n = 1737). Most respondents have positive attitudes to community psychiatry. In the regression analysis (R2 adjusted = 21.2%), negative emotions towards mentally ill people as depicted in the vignette, great social distance, a positive attitude to restrictions, negative stereotypes, high rigidity and no participation in community activities significantly influenced negative attitudes to community psychiatry. Additionally, other parameters, e.g. contact with mentally ill people and the nationality of the interviewee, have a significant influence. In planning psychiatric community services, general individual traits and emotive issues should be considered because they influence the response towards community psychiatry facilities in the host community.

Transition into daylight savings time (DST) has studied negative impacts on health, but little is known regarding impact on fertility. This retrospective cohort study evaluates DST impact on pregnancy and pregnancy loss rates in 1,654 autologous in vitro fertilization cycles (2009 to 2012). Study groups were identified based on the relationship of DST to embryo transfer. Pregnancy rates were similar in Spring and Fall (41.4%, 42.2%). Pregnancy loss rates were also comparable between Spring and Fall (15.5%, 17.1%), but rates of loss were significantly higher in Spring when DST occurred after embryo transfer (24.3%). Loss was marked in patients with a history of prior spontaneous pregnancy loss (60.5%).

Impact of Fecal Incontinence and Its Treatment on Quality of Life in Women

Fecal incontinence (FI) is a physically and psychosocially debilitating disorder which negatively impacts quality of life (QOL). It bears a significant burden not only on patients but also on their families, caretakers, as well as society as a whole. Even though it is considered a somewhat common condition, especially as women age, the prevalence is often underestimated due to patients’ reluctance to report symptoms or seek care. The evaluation and treatment of FI can be also hindered by lack of understanding of the current management options among healthcare providers and how they impact on QOL. This article provides a comprehensive review on the impact of FI and its treatment on QOL in women. PMID:25776296

Physicians work considerably longer hours and are less satisfied with work-life balance than U.S. workers in other fields. There is, however, minimal data on physicians' parental satisfaction. To evaluate differences in parental satisfaction among physicians and workers in other fields, we surveyed U.S. physicians as well as a probability-based sample of the general U.S. working population between August 2014-October 2014. Parental satisfaction and the perceived impact of career on relationships with children were evaluated. Among 6880 responding physicians (cooperation rate 19.2 %), 5582 (81.1 %) had children. Overall, physicians were satisfied in their relationships with their children, with 4782 (85.9 %) indicating that they were either very satisfied [n = 2738; (49.2 %)] or satisfied [n = 2044 (36.7 %)]. In contrast, less than half believed their career had made either a major [n = 1212; (21.8 %)] or minor positive [n = 1260; (22.7 %)] impact on their relationship with their children, with a slightly larger proportion indicating a major (n = 2071 [37.2 %]) or minor (n = 501 [9 %]) negative impact. Women physicians were less likely to believe their career had made a positive impact as were younger physicians. Hours worked/week inversely correlated with the belief that career had made a positive impact on relationships with children. Both men (OR: 2.75; p < 0.0001) and women (OR: 4.33; p < 0.0001) physicians were significantly more likely to report that their career had a negative impact on relationships with their children than the sex-matched U.S. working population. U.S. physicians report generally high satisfaction in their relationships with their children. Despite their high satisfaction, physicians have a more negative perception of the impact of their career on relationships with their children than U.S. workers in general.

Impact of climate change on crop yield and role of model for achieving food security.

PubMed

Kumar, Manoj

2016-08-01

In recent times, several studies around the globe indicate that climatic changes are likely to impact the food production and poses serious challenge to food security. In the face of climate change, agricultural systems need to adapt measures for not only increasing food supply catering to the growing population worldwide with changing dietary patterns but also to negate the negative environmental impacts on the earth. Crop simulation models are the primary tools available to assess the potential consequences of climate change on crop production and informative adaptive strategies in agriculture risk management. In consideration with the important issue, this is an attempt to provide a review on the relationship between climate change impacts and crop production. It also emphasizes the role of crop simulation models in achieving food security. Significant progress has been made in understanding the potential consequences of environment-related temperature and precipitation effect on agricultural production during the last half century. Increased CO2 fertilization has enhanced the potential impacts of climate change, but its feasibility is still in doubt and debates among researchers. To assess the potential consequences of climate change on agriculture, different crop simulation models have been developed, to provide informative strategies to avoid risks and understand the physical and biological processes. Furthermore, they can help in crop improvement programmes by identifying appropriate future crop management practises and recognizing the traits having the greatest impact on yield. Nonetheless, climate change assessment through model is subjected to a range of uncertainties. The prediction uncertainty can be reduced by using multimodel, incorporating crop modelling with plant physiology, biochemistry and gene-based modelling. For devloping new model, there is a need to generate and compile high-quality field data for model testing. Therefore, assessment of agricultural productivity to sustain food security for generations is essential to maintain a collective knowledge and resources for preventing negative impact as well as managing crop practises.

Major depressive disorder (MDD) is a mental disorder that results from complex interplay between multiple and partially overlapping sets of susceptibility genes and environmental factors. The brain derived neurotrophic factor (BDNF) and Protein kinase C gamma type (PRKCG) are logical candidate genes in MDD. Among diverse environmental factors, negative life events have been suggested to exert a crucial impact on brain development. In the present study, we hypothesized that interactions between genetic variants in BDNF and PRKCG and negative life events may play an important role in the development of MDD. We recruited a total of 406 patients with MDD and 391 age- and gender-matched control subjects. Gene-environment interactions were analyzed using generalized multifactor dimensionality reduction (GMDR). Under a dominant model, we observed a significant three-way interaction among BDNF rs6265, PRKCG rs3745406, and negative life events. The gene-environment combination of PRKCG rs3745406 C allele, BDNF rs6265 G allele and high level of negative life events (C-G-HN) was significantly associated with MDD (OR, 5.97; 95% CI, 2.71-13.15). To our knowledge, this is the first report of evidence that the BDNF-PRKCG interaction may modify the relationship between negative life events and MDD in the Chinese population.

Life cycle assessment was conducted to evaluate the energy efficiency and environmental impacts of a bioethanol production system that uses sweet sorghum stem on saline-alkali land as feedstock. The system comprises a plant cultivation unit, a feedstock transport unit, and a bioethanol conversion unit, with 1000L of bioethanol as a functional unit. The net energy ratio is 3.84, and the net energy gain is 17.21MJ/L. Agrochemical production consumes 76.58% of the life cycle fossil energy. The category with the most significant impact on the environment is eutrophication, followed by acidification, fresh water aquatic ecotoxicity, human toxicity, and global warming. Allocation method, waste recycling approach, and soil salinity significantly influence the results. Using vinasse to produce pellet fuel for steam generation significantly improves energy efficiency and decreases negative environmental impacts. Promoting reasonable management practices to alleviate saline stress and increasing agrochemical utilization efficiency can further improve environmental sustainability.

Physical and mental health consequences of Katrina on Vietnamese immigrants in New Orleans: a pre- and post-disaster assessment.

PubMed

Vu, Lung; Vanlandingham, Mark J

2012-06-01

We assessed the health impacts of a natural disaster upon a major immigrant community by comparing pre- and post-event measures for identical individuals. We collected standard health measures for a population-based sample of working-age Vietnamese-Americans living in New Orleans in 2005, just weeks before Katrina occurred. Near the first- and second-year anniversaries of the event, we located and re-assessed more than two-thirds of this original pre-Katrina cohort. We found statistically significant declines in health status for seven of the eight standard SF-36 subscales and for both the physical and mental health component summaries at the first anniversary of the disaster. By the second anniversary, recovery of the health dimensions assessed by these measures was substantial and significant. Most of the SF-36 mental and physical health subscales returned to their original pre-Katrina levels. Being in middle-age, being engaged in professional or self-employed occupations, being unmarried, being less acculturated, and having extensive post-Katrina property damage have statistically significant negative effects on post-Katrina health status, and several of these factors continued to impede recovery by the second anniversary. Hurricane Katrina had significant negative impacts on the mental and physical health of Vietnamese New Orleanians. Several factors present clear opportunities for targeted interventions.

Emotional rigidity is described in clinical literature as a significant barrier to recovery; however, few there are few empirical measures of the construct. The current study had two aims: Study 1 aimed to identify latent factors that may bear on the construct of emotional rigidity while Study 2 assessed the potential impact of the latent factor(s) on anxiety remission rates and well-being. This study utilized data from 2472 adult inpatients (1176 females and 1296 males) with severe psychopathology. Study 1 utilized exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to identify latent factors of emotional rigidity. Study 2 utilized hierarchical logistic regression analyses to assess the relationships among emotional rigidity factors and anxiety remission and well-being recovery at discharge. Study 1 yielded a two-factor solution identified in EFA was confirmed with CFA. Factor 1 consisted of neuroticism, experiential avoidance, non-acceptance of emotions, impaired goal-directed behavior, impulse control difficulties and limited access to emotion regulation strategies when experiencing negative emotions. Factor 2 consisted of lack of emotional awareness and lack of emotional clarity when experiencing negative emotions. Results of Study 2 indicated higher scores on Factor 1 was associated with lower remission rates from anxiety and poorer well-being upon discharge. Factor 2 was not predictive of outcome. Emotional rigidity appears to be a latent construct that negatively impacts remission rates from anxiety. Limitations of the present study include its retrospective design, and inefficient methods of assessing emotional rigidity. Copyright © 2018. Published by Elsevier B.V.

Objective Stigma associated with mental illness continues to be a significant barrier to help seeking, leading to negative attitudes about mental health treatment and deterring individuals who need services from seeking care. This study examined the impact of public stigma (negative attitudes held by the public) and internalized stigma (negative attitudes held by stigmatized individuals about themselves) on racial differences in treatment seeking attitudes and behaviors among older adults with depression. Method Random digit dialing was utilized to identify a representative sample of 248 African American and White adults older adults (over the age of 60) with depression (symptoms assessed via the Patient Health Questionnaire-9). Telephone based surveys were conducted to assess their treatment seeking attitudes and behaviors, and the factors that impacted these behaviors. Results Depressed older adult participants endorsed a high level of public stigma and were not likely to be currently engaged in, nor did they intend to seek mental health treatment. Results also suggested that African American older adults were more likely to internalize stigma and endorsed less positive attitudes toward seeking mental health treatment than their White counterparts. Multiple regression analysis indicated that internalized stigma partially mediated the relationship between race and attitudes toward treatment. Conclusion Stigma associated with having a mental illness has a negative influence on attitudes and intentions toward seeking mental health services among older adults with depression, particularly African American elders. Interventions to target internalized stigma are needed to help engage this population in psychosocial mental health treatments. PMID:20220602

To explore pharmacists' perceived responsibility to assist Part D patients in the community in managing their out-of-pocket (OOP) costs as well as pharmacists' overall experience with Medicare Part D. Cross-sectional analysis. Maine, New Jersey, New York, Massachusetts, Maryland, and Pennsylvania. 272 pharmacists. 37-question online survey. Perceived responsibility to assist Part D patients in managing their OOP costs and pharmacists' overall experience with Medicare Part D. Of the 4,888 online surveys, 1,108 were assumed to have reached the intended recipients, of which 272 responded (adjusted response rate 25.0%). Fifty-seven percent, 43.3%, and 41.9% of pharmacists reported that it was not their responsibility to address Part D patients' copayment/cost issue, prior authorization issues, or dispense preferred formulary medications, respectively. However, 43.2% reported that their most time-consuming task in reference to Part D were addressing formulary and copayment issues. In reference to overall experience with Part D, 42.9% reported that the impact on pharmacy's workflow was negative or very negative. A significant difference was observed between pharmacists' practice settings, the state in which they practiced, and reporting of negative impact of Part D on workflow (χ² = 4.9, P = 0.028; χ² = 6.16, P = 0.013, respectively). Most community pharmacists reported that it was not their responsibility to address patients' OOP costs issues, though a majority reported that the most time-consuming task in reference to Part D was addressing formulary and copayment issues. Almost half of the pharmacists also reported that the impact of Part D on workflow was negative.

Ants have a negative rather than a positive effect on extrafloral nectaried Crotalaria pallida performance

Pereira, Marcela Fernandes; Trigo, José Roberto

2013-08-01

Crotalaria pallida (Fabaceae) is a pantropical plant with extrafloral nectaries (EFNs) near the reproductive structures. EFN-visiting ants attack and remove arctiid moth Utetheisa ornatrix larvae, the main pre-dispersal seed predator, but the impact of ants on C. pallida fitness is unknown. To assess this impact, we controlled ant presence on plants and evaluated the reproductive output of C. pallida with and without ants. Predatory wasps also visit EFNs, prey upon U. ornatrix larvae, and may be driven out by ants during EFN feeding. Does this agonistic interaction affect the multitrophic interaction outcome? We found it difficult to evaluate the effect of both visitors because cages excluding wasps affect plant growth and do not allow U. ornatrix oviposition. Therefore, we verified whether ant presence inhibited wasp EFN visitation and predicted that (1) if ants confer a benefit for C. pallida, any negative effect of ants on wasps would be negligible for the plant because ants would be the best guardians, and (2) if ants are poor guardians, they would negatively affect wasps and negatively impact the fitness of C. pallida. Surprisingly, we found that the number of seeds/pods significantly increased, ca. 4.7 times, after ant removal. Additionally, we unexpectedly verified that controls showed a higher percentage of herbivore bored pods than ant-excluded plants. We found that wasps spent less time visiting EFNs patrolled by ants (ca. 299 s less). These results support our second prediction and suggest that the outcome of multitrophic interactions may vary with natural enemy actors.

Follicle stimulating hormone receptor (FSHR) and luteinizing hormone receptor (LHCGR) were demonstrated to impact upon survival of patients suffering from epithelial ovarian cancer (EOC). Though structure wise the G-protein coupled estrogen receptor (GPER/GPR30) is related to FSHR/LHCGR, its prognostic impact in EOC remains controversial. We recently found that FSHR negative patients represent a specific EOC subgroup that may behave differently in respect to both treatment response and prognosis. Hence, the current study aimed to analyze how GPER may interact with the FSHR/LHCGR system in EOC and whether the prognostic significance of GPER in EOC cases (n=151) may be dependent on the FSHR/LHCGR immunophenotype of the tumor. Ovarian cancer cell lines were used to study how FSH and LH regulate GPER and whether GPER activation differentially affects in vitro cell proliferation in presence/absence of activated FSHR/LHCGR. In EOC tissue, GPER correlated with FSHR/LHCGR and was related to prolonged overall survival only in FSHR/LHCGR negative patients. Although GPER was found to be specifically induced by LH/FSH, GPER agonists (4-Hydroxy-Tamoxifen, G1) reduced EOC cell proliferation only in case of LH/FSH unstimulated pathways. To the same direction, only patients characterized as LHCGR/FSHR negative seem to gain from GPER in terms of survival. Our combined tissue and in vitro results support thus the hypothesis that GPER activation could be of therapeutic benefit in LHCGR/FSHR negative EOC patients. Further studies are needed to evaluate the impact of GPER activation on a clinical scheme.

Preterm birth is a stressful event for families. In particular, the unexpectedly early delivery may cause negative feelings in mothers and fathers. The aim of this study was to examine the relationship between preterm birth, parental stress and negative feelings, and the environmental setting of NICU. 21 mothers (age = 36.00 ± 6.85) and 19 fathers (age = 34.92 ± 4.58) of preterm infants (GA = 30.96 ± 2.97) and 20 mothers (age = 40.08 ± 4.76) and 20 fathers (age = 40.32 ± 6.77) of full-term infants (GA = 39.19 ± 1.42) were involved. All parents filled out the Parental Stressor Scale: Neonatal Intensive Care Unit, the Impact of Event Scale Revised, Profile of Mood States, the Multidimensional Scale of Perceived Social Support and the Post-Partum Bonding Questionnaire. Our data showed differences in emotional reactions between preterm and full-term parents. Results also revealed significant differences between mothers and fathers’ responses to preterm birth in terms of stress, negative feelings, and perceptions of social support. A correlation between negative conditions at birth (e.g., birth weight and Neonatal Intensive Care Unit stay) and higher scores in some scales of Impact of Event Scale Revised, Profile of Mood States and Post-Partum Bonding Questionnaire were found. Neonatal Intensive Care Unit may be a stressful place both for mothers and fathers. It might be useful to plan, as soon as possible, interventions to help parents through the experience of the premature birth of their child and to begin an immediately adaptive mode of care.

Annual costs paid by families for intravenous infusion of home parenteral nutrition (HPN) health insurance premiums, deductibles, co-payments for health services, and the wide range of out-of-pocket home health care expenses are significant. The costs of managing complex chronic care at home cannot be completely understood until all out-of-pocket costs have been defined, described, and tabulated. Non-reimbursed and out-of-pocket costs paid by families over years for complex chronic care negatively impact the financial stability of families. National health care reform must take into account the long-term financial burdens of families caring for those with complex home care. Any changes that may increase the out-of-pocket costs or health insurance costs to these families can also have a negative long-term impact on society when greater numbers of patients declare bankruptcy or qualify for medical disability.

Primary care in an era of hospital bed reduction: what can we infer from QOF and PBC?

PubMed

Checkland, Kath; Harrison, Stephen

2010-12-01

The Quality and Outcomes Framework (QOF) has been efficiently and effectively incorporated into practice routines. One possible negative effect of this has been a move towards a more biomedical form of practice.There has been patchy but real engagement with practice-based commissioning (PBC), with significant moves in some areas towards GPs acting collectively to improve services across the health economy, including engaging in performance management of each others' practice.Together, responses to QOF and PBC suggest that GPs may be willing and able to act both individually and collectively to try to mitigate the negative impacts of future spending reductions. General practice will be under a great deal of pressure in the next few years. Understanding the impact of past policy changes is essential if we are to ensure that the core values of general practice are maintained.

Racism, Racial Resilience, and African American Youth Development: Person-Centered Analysis as a Tool to Promote Equity and Justice.

Racism constitutes a significant risk to the healthy development of African American youth. Fortunately, however, not all youth who experience racism evidence negative developmental outcomes. In this chapter, we examine person-centered analysis (PCA)-a quantitative technique that investigates how variables combine across individuals-as a useful tool for elucidating racial and ethnic protective processes that mitigate the negative impact of racism. We review recent studies employing PCA in examinations of racial identity, racial socialization, and other race-related experiences, as well as how these constructs correlate with and impact African American youth development. We also consider challenges and limitations of PCA and conclude with a discussion of future research and how PCA might be used to promote equity and justice for African American and other racial and ethnic minority youth who experience racism. © 2016 Elsevier Inc.

The problems with China's regional industrial overcapacity are often influenced by local governments. This study constructs a framework that includes the resource and environmental costs to analyze overcapacity using the non-radial direction distance function and the price method to measure industrial capacity utilization and market segmentation in 29 provinces in China from 2002 to 2014. The empirical analysis of the spatial panel econometric model shows that (1) the industrial capacity utilization in China's provinces has a ladder-type distribution with a gradual decrease from east to west and there is a severe overcapacity in the traditional heavy industry areas; (2) local government intervention has serious negative effects on regional industry utilization and factor market segmentation more significantly inhibits the utilization rate of regional industry than commodity market segmentation; (3) economic openness improves the utilization rate of industrial capacity while the internet penetration rate and regional environmental management investment have no significant impact; and(4) a higher degree of openness and active private economic development have a positive spatial spillover effect, while there is a significant negative spatial spillover effect from local government intervention and industrial structure sophistication. This paper includes the impact of resources and the environment in overcapacity evaluations, which should guide sustainable development in emerging economies.

An Overview of Soils and Human Health - Research Trends and Future Needs

Brevik, Eric C.; Burgess, Lynn C.; Steffan, Joshua J.; Cerdà, Artemi

2017-04-01

Soils have significant impact on human health, whether those influences are positive or negative, direct or indirect. Soils are a significant source of nutrients in our food supply and medications such as antibiotics. However, nutrient imbalances and the presence of human pathogens in the soil biological community can cause negative impacts on health. There are also many locations where various elements or chemical compounds are found in soils at toxic levels, due to either natural conditions or anthropogenic activities. The soils of urban environments have received increased attention in the last few years, and they too pose a number of human health questions and challenges. Concepts such as soil security may provide a framework within which soils and human health issues can be investigated using interdisciplinary and transdisciplinary approaches, as it will take the contributions of experts in a number of different scientific, medical, and social science fields to fully address soils and human health issues. While much progress was made in understanding links between soils and human health over the last century, there is still much we do not know and the interactions between soils and human health are extremely complex. Therefore, there is still significant need for research in this important area.

Genetic assessment of a summer chum salmon metapopulation in recovery

2014-01-01

Programs to rebuild imperiled wild fish populations often include hatchery-born fish derived from wild populations to supplement natural spawner abundance. These programs require monitoring to determine their demographic, biological, and genetic effects. In 1990s in Washington State, the Summer Chum Salmon Conservation Initiative developed a recovery program for the threatened Hood Canal summer chum salmon Evolutionarily Significant Unit (ESU) (the metapopulation) that used in-river spawners (wild fish) for each respective supplementation broodstock in six tributaries. Returning spawners (wild-born and hatchery-born) composed subsequent broodstocks, and tributary-specific supplementation was limited to three generations. We assessed impacts of the programs on neutral genetic diversity in this metapopulation using 16 microsatellite loci and a thirty-year dataset spanning before and after supplementation, roughly eight generations. Following supplementation, differentiation among subpopulations decreased (but not significantly) and isolation by distance patterns remained unchanged. There was no decline in genetic diversity in wild-born fish, but hatchery-born fish sampled in the same spawning areas had significantly lower genetic diversity and unequal family representation. Despite potential for negative effects from supplementation programs, few were detected in wild-born fish. We hypothesize that chum salmon natural history makes them less vulnerable to negative impacts from hatchery supplementation. PMID:24567747

2015-01-01

Tourism accounts for 9% of global GDP and comprises 1.1 billion tourist arrivals per annum. Visits to wildlife tourist attractions (WTAs) may account for 20-40% of global tourism, but no studies have audited the diversity of WTAs and their impacts on the conservation status and welfare of subject animals. We scored these impacts for 24 types of WTA, visited by 3.6-6 million tourists per year, and compared our scores to tourists' feedback on TripAdvisor. Six WTA types (impacting 1,500-13,000 individual animals) had net positive conservation/welfare impacts, but 14 (120,000-340,000 individuals) had negative conservation impacts and 18 (230,000-550,000 individuals) had negative welfare impacts. Despite these figures only 7.8% of all tourist feedback on these WTAs was negative due to conservation/welfare concerns. We demonstrate that WTAs have substantial negative effects that are unrecognised by the majority of tourists, suggesting an urgent need for tourist education and regulation of WTAs worldwide.

The relationship between academic achievement and the subjective well-being of elementary school children has received increasing attention. However, previous research on the relationship between these variables has yielded inconsistent conclusions – possibly due to the presence of potential moderating variables. This study investigated the relationship between the academic achievement and the emotional well-being (positive and negative affect) of elementary school children in China and the moderating effect of parent–school communication on this relationship. A total of 419 elementary school students and their parents participated. The elementary students’ positive and negative affect, their academic achievement on both midterm and final examinations of the most recent semester, and the frequency of parent–school communication were assessed. Academic achievement of elementary students was positively correlated with positive affect and negatively correlated with negative affect. Parent–school communication significantly moderated this relationship. Regardless of positive or negative affect, the correlation was only significant in the high parent–school communication group (one standard deviation higher than the mean) and in the mean group, whereas in the low parent–school communication group, no association was observed. These results indicate that parental engagement with school impacts both the academic achievements and subjective well-being of children in China. PMID:27445915

A lack of insight into illness and negative attitudes towards medication are common among individuals with schizophrenia and impact clinical outcomes. This study aimed to examine the relationships between attitudes towards medication and cognitive function in schizophrenia patients. Thirty-five male forensic inpatients who were suffering from chronic schizophrenia participated in the study. A drug attitude inventory was used to evaluate the attitudes of the patients towards medication. Neuropsychological function was assessed with a comprehensive battery of tests. Patients with positive attitudes towards medication performed significantly better than those with negative attitudes on tests of verbal working memory (digit span forwards and backwards), inhibition and set shifting (Penn Inhibition test), delayed object memory and overall mental status (Mini Mental State Examination). There were no differences in age, education, hospitalizations or clinical symptoms between the groups. Our findings support an association between negative attitudes towards medication and poor cognitive performance, particularly of working memory.

Negative Bystander Behavior in Bullying Dynamics: Assessing the Impact of Social Capital Deprivation and Anti-social Capital.

PubMed

Evans, Caroline B R; Smokowski, Paul R

2017-02-01

Bystanders witness bullying, but are not directly involved as a bully or victim; however, they often engage in negative bystander behavior. This study examines how social capital deprivation and anti-social capital are associated with the likelihood of engaging in negative bystander behavior in a sample (N = 5752) of racially/ethnically diverse rural youth. Data were collected using an online, youth self-report; the current study uses cross sectional data. Following multiple imputation, a binary logistic regression with robust standard errors was run. Results partially supported the hypothesis and indicated that social capital deprivation in the form of peer pressure and verbal victimization and anti-social capital in the form of delinquent friends, bullying perpetration, verbal perpetration, and physical perpetration were significantly associated with an increased likelihood of engaging in negative bystander behavior. Findings highlight the importance of establishing sources of positive social support for disenfranchised youth.

Strain, Negative Emotions, and Level of Criminality Among Chinese Incarcerated Women.

Sun, Ivan Y; Luo, Haishan; Wu, Yuning; Lin, Wen-Hsu

2016-05-01

General strain theory (GST) has been one of the most frequently tested criminological theories. According to GST, strain tends to generate negative emotions, which create pressures for corrective action, such as crime and delinquency. Although GST has received strong empirical support, one under-addressed issue is the lack of diversity in sampling population in assessing the generalizability of the theory. Using survey data collected from 335 incarcerated women in four Chinese prisons, this study examined the impact of strain and negative emotions on the level of female criminality. The strain variable, physical abuse, and discrimination, exerted a positive effect on female inmates' levels of criminality, whereas negative emotions were not significantly related to female criminality.

Using two modes of intervention delivery, the present study compared the effects of a cognitive defusion strategy with a thought distraction strategy on the emotional discomfort and believability of negative self-referential thoughts. One mode of intervention delivery consisted of a clinical rationale and training (i.e., Partial condition). The other mode contained a condition-specific experiential exercise with the negative self-referential thought in addition to the clinical rationale and training (i.e., Full condition). Nonclinical undergraduates were randomly assigned to one of five protocols: Partial-Defusion, Full-Defusion, Partial-Distraction, Full-Distraction, and a distraction-based experimental control task. The Full-Defusion condition reduced the emotional discomfort and believability of negative self-referential thoughts significantly more than other comparison conditions. The positive results of the Full-Defusion condition were also found among participants with elevated depressive symptoms.

The large-scale impacts of the Arctic Oscillation (AO) and the East Atlantic/West Russia (EA/WR) teleconnection on the East Asian winter climate anomalies are compared for the past 34 winters focusing on 1) interannual monthly to seasonal temperature variability, 2) East Asian winter monsoon (EAWM), and 3) the Siberian high (SH) and cold surge. Regression analysis reveals warming by AO and EA/WR over mid-latitude East Asia during their positive phase and vice versa. The EA/WR impact is found to be comparable to the AO impact in affecting the East Asian temperature and monsoon. For example, warm (cold) months over mid-latitude East Asia during the positive (negative) AO are clearly seen when the AO and EA/WR are in the same phase. Near zero correlation is found between temperature and the AO phase when both teleconnections are in an opposite phase. The well-known negative relationship between SH and the AO phase is observed significantly more often when the AO is in the same phase with the EA/WR. Also, the indices of EAWM, cold surge, and SH are found to be more highly negative-correlated with the EA/WR rather than with the AO. The advective temperature change and associated circulation demonstrate that the anomalous large-scale field including the SH over the mid-latitude Asian inland is better represented by the EA/WR, influencing the East Asian winter climates. These results suggest that the impact of EA/WR should be considered more important than previously thought for a better understanding of East Asian winter temperature and monsoon variability.

While supportive breeding programmes strive to minimize negative genetic impacts to populations, case studies have found evidence for reduced fitness of artificially produced individuals when they reproduce in the wild. Pedigrees of two complete generations were tracked with molecular markers to investigate differences in reproductive success (RS) of wild and hatchery-reared Chinook salmon spawning in the natural environment to address questions regarding the demographic and genetic impacts of supplementation to a natural population. Results show a demographic boost to the population from supplementation. On average, fish taken into the hatchery produced 4.7 times more adult offspring, and 1.3 times more adult grand-offspring than naturally reproducing fish. Of the wild and hatchery fish that successfully reproduced, we found no significant differences in RS between any comparisons, but hatchery-reared males typically had lower RS values than wild males. Mean relative reproductive success (RRS) for hatchery F1 females and males was 1.11 (P = 0.84) and 0.89 (P = 0.56), respectively. RRS of hatchery-reared fish (H) that mated in the wild with either hatchery or wild-origin (W) fish was generally equivalent to W × W matings. Mean RRS of H × W and H × H matings was 1.07 (P = 0.92) and 0.94 (P = 0.95), respectively. We conclude that fish chosen for hatchery rearing did not have a detectable negative impact on the fitness of wild fish by mating with them for a single generation. Results suggest that supplementation following similar management practices (e.g. 100% local, wild-origin brood stock) can successfully boost population size with minimal impacts on the fitness of salmon in the wild.

The genesis of schizophrenia is multifactorial, including biological and environmental risk factors. We tested for an interactive effect between early-onset schizophrenia (EOS) and social class of origins (socioeconomic status (SES)). Data were further analyzed for a possible connection to type of schizophrenic symptoms. Sampling/Methods: Data for the study are taken from the medical records of 642 patients from a large state hospital in the northeastern United States. Clinical assessments were divided into positive and negative symptomatology through application of the Scale for the Assessment of Negative Symptoms (SANS), the Scale for the Assessment of Positive Symptoms (SAPS) and the Positive and Negative Syndrome Scale (PANSS). Detailed information about age of onset and SES of origin was obtained through Social Service Assessment interviews. We uncovered a significant impact of EOS among the poor that elevates risk for negative symptomatology. Poor SES alone does not increase the likelihood of EOS, but it magnifies the deleterious effect of EOS on negative symptoms. Future research on these variables may inform the relative contribution of each.

Cognitive behavioural models of eating disorders highlight low self-esteem as a maintaining factor. This study explored the impact of positive and negative self-imagery on aspects of the working self (implicit and explicit self-esteem and self-concept clarity) in individuals with high body dissatisfaction (an important aspect of eating disorders). The impact of these images on state body satisfaction and affect was also explored. A group of participants with high body dissatisfaction completed measures of explicit self-esteem, self-concept clarity, state body satisfaction and affect prior to completing a negative (n = 33) or positive (n = 33) self-imagery retrieval task. Following this they completed the baseline measures and a measure of implicit self-esteem. Holding a negative self-image in mind had a negative effect on explicit self-esteem, whilst holding a positive self-image had a beneficial effect. There were no effects of imagery on implicit self-esteem. Holding a negative image in mind led to a significant reduction in self-concept clarity; however, positive self-imagery did not affect self-concept clarity. Holding a negative self-image in mind led to a decrease in body satisfaction and state affect. The opposite was found for the positive self-imagery group. Implicit self-esteem was not measured at baseline. Imagery techniques which promote positive self-images may help improve aspects of the working self, body satisfaction and affect in individuals with high levels of body dissatisfaction. As such, these imagery techniques warrant further investigation in a clinical population. Copyright © 2014 Elsevier Ltd. All rights reserved.

Sentinel lymph node biopsy is widely accepted as standard care in melanoma despite lack of pertinent randomized trials results. A possible pitfall of this procedure is the inaccurate identification of the sentinel lymph node leading to biopsy and analysis of a nonsentinel node. Such a technical failure may yield a different prognosis. The purpose of this study is to analyze the incidence of false negativity and its impact on clinical outcome and to try to understand its causes. The Melanoma Data Base at National Cancer Institute of Naples was analyzed comparing results between false-negative and tumor-positive sentinel node patients focusing on overall survival and prognostic factors influencing the clinical outcome. One hundred fifty-one cases were diagnosed to be tumor-positive after sentinel lymph node biopsy and were subjected to complete lymph node dissection. Thirty-four (18.4%)patients with tumor-negative sentinel node subsequently developed lymph node metastases in the basin site of the sentinel procedure. With a median follow-up of 42.8 months the 5-year overall survival was 48.4% and 66.3% for false-negative and tumor-positive group respectively with significant statistical differences (P < .03). The sensitivity of sentinel lymph node biopsy was 81.6%, and a regional nodal basin recurrence after negative-sentinel node biopsy means a worse prognosis, compared with patients submitted to complete lymph node dissection after a positive sentinel biopsy. The evidence of higher number of tumor-positive nodes after delayed lymphadenectomy in false-negative group compared with tumor-positive sentinel node cases, confirmed the importance of an early staging of lymph nodal involvement. Further data will better clarify the role of prognostic factors to identify cases with a more aggressive biological behavior of the disease.

The aim of the study was to determine the occupational activity of epileptic patients. Particular attention was paid to employment of people with epilepsy, the way the workplace is informed about the disease, impact of education on employment opportunities and the relationship between clinical type of epilepsy and professional activity. Patients were recruited from the neurological outpatient clinic in Warszawa and asked to fill in a customized questionnaire, containing questions on their socio-demographic, clinical and employment status. The study included 197 adult patients with epilepsy (64 professionally active and 133 inactive). As many as 47.7% of respondents declared that the disease impeded their employment, and 77.2% admitted that the occurrence of seizure at work had negatively affected their comfort. As many as 42.2% professionally active respondents had revealed the disease at work. There was a statistically significant difference between individuals with primarily generalized seizures and those with partial and secondarily generalized seizures (30.61% vs. 2.63%, p<0.05). Education had also a significant positive impact on employment (47.06% employed with university degree vs. 9.76% with primary education, p<0.05). No significant correlations between duration of the disease or number of the epileptic seizures, independent of their type and revealing the disease in the workplace, were observed (p>0.05). Neither current work status had impact on opinions about difficulties in finding a job (p>0.05). Epilepsy is a great obstacle to finding and maintaining employment. Less than 1/2 of patients inform the workplace about their illness, mainly due to previous negative experiences. Since education significantly enables the employment, programs aimed at promoting vocational activation of patients should facilitate access to learning.
